the detailed description set forth below in connection with the appended drawings is intended as a description of presently - preferred embodiments of the invention and is not intended to represent the only forms in which the present invention may be constructed or utilized . the description sets forth the functions and the sequence of steps for constructing and operating the invention in connection with the illustrated embodiments . it is to be understood , however , that the same or equivalent functions and sequences may be accomplished by different embodiments that are also intended to be encompassed within the spirit and scope of the invention . the fall protection guardrail described herein includes a novel support bracket 2 that attaches to framing 4 and holds a pole 6 that has a top end 5 and a bottom end 7 . as shown in a preferred embodiment depicted in fig1 and 2 , the support bracket 2 may comprise two components , an attachment member 8 and a pole support 10 . the attachment member 8 may be constructed of an attachment face 12 , with a first surface 14 and a second surface 16 , and four sides . the attachment face 12 may be rectangular and substantially planar , and its surface may define at least one attachment hole 56 . on one or more sides of the attachment face 12 , reinforcing members 18 a - d are coupled with the attachment face 12 . the reinforcing members 18 a - d may be planar rectangles such as flat bar stock , typically arranged perpendicular to the attachment face 12 . the reinforcing members 18 may also be other shapes ( not shown ) such as an l - shape ( angle iron ), square or rectangular tubing , channel bar , i - beam , t - bar , or any other suitable shape , and may be arranged in any suitable configuration on the attachment face 12 . in a preferred embodiment the attachment face 12 is approximately 10 inches ( 25 . 4 cm )× 6 inches ( 15 . 24 cm ), although other dimensions may be used . in a preferred embodiment , the attachment member 8 may be comprised of a single sheet of steel , with cut out corners , wherein the sides are folded up on the first side of the attachment face 12 to form the reinforcing members 18 a - d , and their corners are fastened together , typically by welding , but any suitable attachment method may be used . the resulting open “ box ” may have three sides 18 a - c or four sides 18 a - d . alternatively , the reinforcing members 18 a - d can comprise separate bar stock or other shapes described above , welded or otherwise coupled with the attachment face 12 , again with three or four sides . in either case , the attachment member may comprise a top reinforcing member 18 a , a bottom reinforcing member 18 c opposite and parallel to the top reinforcing member 18 a , and a side reinforcing member adjacent 18 b , perpendicular , and attached to the top and bottom reinforcing members 18 a , 18 c to form the open box configuration , wherein the side reinforcing member 18 b is opposite the pole support 10 . in some embodiments , the pole support 10 may make up the fourth reinforcing member to complete the open box configuration . in other embodiments , a second side reinforcing member 18 d may be attached to the attachment member 8 opposite the first side reinforcing member 18 b and adjacent and perpendicular to the top and bottom reinforcing members 18 a , 18 c . the pole support 10 may be attached to the second side reinforcing member 18 d . in a preferred embodiment , the pole support 10 may be constructed of square tubing , although other shapes of tubing may be used so long as the tubing comprises at least one wall 11 defining a first cavity 13 . as used herein , the term “ square tubing ” shall include any rectangular tubing with equal or unequal side dimensions . square tubing may be advantageous to keep the pole 6 in a certain orientation without use of a pin , and also has greater bending strength than round tubing for a given thickness when the moment is in line with the sides of the tubing . square tubing may also be easier to attach to the square sides of the attachment member 8 “ box .” square tubing also has an advantage if a safety pin is used , described below . nevertheless , other shapes of tubing may be used for the pole support 10 . however , non - cylindrical shaped tubing is preferred to prevent unwanted rotation of the pole 6 within the pole support 10 . in a preferred embodiment , the pole support 10 is comprised of square tubing defining a first cavity 13 having a first cavity dimension of approximately 1 . 25 inches ( 3 . 175 cm ) by 1 . 25 inches and an outer pole support dimension of approximately 1 . 5 inches ( 3 . 81 cm ) by 1 . 5 inches , although other dimensioned tubing may be used . the attachment member 8 may then be coupled with the pole support 10 . the pole support 10 may be coupled with the attachment member 8 by welding or other suitable methods . in a preferred embodiment , the attachment member 8 is a three - sided “ box ,” and the pole support 10 is a piece of square tubing with a side dimension that is the same width as the reinforcing members 18 a - c , wherein the square tubing may be welded or otherwise coupled with the attachment member 8 so that the square tubing becomes the fourth side of the “ box ” and acts as a reinforcing member 18 d . as shown in fig1 and 2 , in a preferred embodiment the attachment member 8 is a rectangle with unequal sides , where one of the long sides is coupled with the pole support 10 . although the pole support 10 is shown as being the same length as the long side of the attachment member 8 , the pole support 10 could be longer or shorter . as shown in fig1 and 2 , in a preferred embodiment a positioning member 20 is attached to the second surface 16 of the attachment face 12 . the purpose of the positioning member 20 is to act as a stop to accurately position a first portion of the second surface 16 of the attachment face 12 of the attachment member 8 that is distal to the pole support 10 against a building framing member 4 , as shown in fig3 . preferably , the first portion of the second surface 16 of the attachment face 12 touching the framing member 4 ( referred to as the “ attachment surface ” 22 ) is approximately equal to the width of the framing member 4 , although it may be wider or narrower . for example , for a building made with 2 × 4 framing members 4 ( which are nominally 1 . 5 inches × 3 . 5 inches ( 3 . 81 cm × 8 . 89 cm )), the attachment surface 22 would be 3 . 5 inches wide . for a building with framing members 4 that are larger , the attachment surface 22 could be sized to match , or be kept at the same 3 . 5 inch size , or made larger or smaller . although the positioning member 20 is shown as a piece of angle iron in fig1 - 3 , it may be any suitable structure that makes the attachment surface 22 the appropriate dimension , whether it be one or more “ ears ” cut into the attachment face 12 and bent up to act as a stop , or some other type of bar stock , round stock , or any suitable shaped protrusion . the attachment surface 22 may be equipped with attachment holes 56 to accommodate fasteners 42 , described below . in some embodiments , the attachment face 12 may have attachment holes 56 on both sides of the positioning member 20 . this allows the attachment member 8 to be attached to a framing member with the first surface 14 facing the framing members 4 . this may be suitable when framing members 4 are made with large 2 × 6 or 2 × 8 beams , and the like . stronger screws or fastening devices may be used to secure the attachment member 8 in this manner . as shown in fig3 , a pole 6 may be adapted to fit into the pole support 10 and equipped with a pole stop 24 in between the top end 5 and the bottom end 7 , but preferably near its bottom end 7 . thus , the bottom end 7 defines a pole support insert 9 . the pole stop 24 insures that the pole support insert 9 is suitably inserted into the pole support 10 , but insures the pole 6 cannot slip further into the pole support 10 than necessary . the pole stop 24 may be constructed of bar stock or square tubing that is the same dimension as the pole support 10 , and welded or suitably fastened to the pole 6 at the desired location . in a preferred embodiment , the pole 6 is comprised of square tubing that has an inner dimension of approximately 1 . 0 inches ( 2 . 54 cm ) by 1 inch , and an outer dimension of approximately 1 . 25 inches ( 3 . 175 cm ) by 1 . 25 inch . as shown in fig3 , both the pole support 10 and the pole 6 may be equipped with corresponding pole locking pin holes 26 , 27 , through which a pole locking pin 28 may be inserted to prevent the pole 6 from accidentally falling or lifting out of the pole support 10 . the pin holes 26 , 27 may be spaced apart in regular increments , such as two inch increments so that the proper height of the pole 6 can be selected , for example to accommodate 10 - inch , 12 - inch , 14 - inch floor joists , and the like . the pole locking pin 28 may be a standard spring and ball detent pin , such as those sold under the kwik - lok ® brand , with or without a release button , or any other suitable locking pin , including but not limited to heavy duty cotter pins , pintle pins , industrial safety and snap pins , or other suitable retaining pins . the pole locking pin 28 may be attached to either the pole 6 , the support bracket 2 or the pole support 10 by a wire cable or other suitable retaining device , so that that a pole locking pin 28 is always within reach . as shown in fig4 , in a preferred embodiment the upper portion of the pole 6 is comprised of a lower rail support 30 and an upper rail support 32 . the rail supports 30 , 32 may be constructed of bar stock welded into the desired configuration . in a preferred embodiment , the rail support is comprised of an l - shaped piece of bar stock that is coupled with the pole 6 near the top end and a diagonal element 38 coupled with the l - shaped piece of bar stock . the l - shaped piece of bar stock comprises a horizontal element 34 and vertical element 36 connected at a corner 35 . the diagonal element 38 is coupled to the corner 35 of the “ l ” and also coupled with the pole 6 at a position distal to the pole &# 39 ; s 6 top end to act as a support for the “ l .” in particular , the diagonal element 38 has a first end 37 and a second end 39 opposite the first end 37 , the first end 37 of the diagonal element 38 coupled to the corner 35 of the l - shaped piece of bar stock and the second end 39 of the diagonal element 38 attached to the pole 6 at a position below the horizontal element 34 to act as a support for the l - shaped piece of bar stock . the rail supports 30 , 32 may be constructed in any configuration or manner to provide sufficient support for the rails 44 . the rails 44 are elongated structures , each rail having a length l , a width w , and a thickness t , wherein the length l is greater than the width w , and the width w is greater than or equal to the thickness t . in a preferred embodiment , the vertical element 36 of the “ l ” of the rail support is at least as tall as the width w of the rail 44 . the vertical element 36 of the “ l ” of the upper rail support 32 would typically terminate at or near the same height as the pole 6 . for example , when using 2 × 4 lumber as rails 44 , the vertical element 36 of the “ l ” of the rail support would be at least 3 . 5 ″ tall . in a preferred embodiment , the horizontal element 34 of the “ l ” of the rail support may have a length that is approximately twice the thickness t of the rail 44 to accommodate two rails 44 , as shown in fig6 - 9 . for example , when using 2 × 4 lumber as rails 44 , the horizontal element 34 of the “ l ” of the rail support would be at least 3 . 0 inches ( 7 . 62 cm ) wide on the interior , to accommodate two rails 44 , each having a thickness t of 1 . 5 inches with a bit of excess space to allow some play . as shown in fig4 , a framed wall 40 is typically constructed on the ground or other horizontal surface . when the wall framing is complete but still lying horizontally , the attachment surface 22 of the support bracket 2 may be placed against a framing member 4 , and attached to the framing member 4 by screws , nails , or other fasteners 42 driven through the attachment holes 56 into the framing member 4 . as shown in fig1 and 2 , the topmost reinforcing member may also have one or more attachment holes 56 , and a fastener 42 may be driven through the hole ( s ) and into the top plate 42 of the wall framing 40 . the fasteners 42 should be of sufficient strength to hold the support bracket 2 to the framing member 4 when the guardrail system is assembled and under the specified minimum load . in a typical configuration , the support bracket 2 is fastened to the framed wall 40 such that the pole support 10 is located on the outside of the wall . at some point , preferably before the framed wall 40 is raised to the vertical position , the pole 6 is placed into the pole support 10 . a pole locking pin 28 may be inserted into the pole locking pin holes 26 , 27 as shown in fig5 . then the wall is raised to the vertical position and secured to other framing , and the guardrail supports are already in position . once the floor ( not shown ) is attached to the top of the framed wall 40 , the rails 44 can be placed into the rail supports 30 , 32 . in a preferred embodiment , the vertical element 36 of the “ l ” of each rail support would be taller than the width w of the rail 44 to accommodate a rail locking pin 46 to function as the retention device . as shown in fig6 , in such a configuration , the pole 6 and the vertical element 36 of the “ l ” of the rail support would define corresponding rail locking pin holes 48 , which are typically located slightly higher than the largest dimension of the rail . after the rails 44 are placed into the rail supports 30 , 32 , the rail locking pins 46 are inserted into the rail locking pin holes 48 , 49 to retain the rails 44 in the rail supports 30 , 32 , as shown in fig6 . in alternative embodiments , the rails 44 may be retained in the rail supports 30 , 32 by other structures that serve as the retention device . in fig7 - 9 , one such alternative embodiment is shown , which comprises a vertical element 36 of the “ l ” of the rail support that is the same height or slightly shorter than the larger dimension of the rail , and a retention clamp 50 as the retention device , which may be an “ l ” shaped element coupled with the pole 6 by a hinge 52 or other suitable attachment method or apparatus . the vertical element 36 of the “ l ” of the rail support and the retention clamp 50 may have corresponding retention holes 54 , 55 and a nail , screw , or other fastener 42 may be driven through the retention holes 54 , 55 and into one or both rails 44 to secure the rails 44 in the rail support , as shown in fig7 - 9 . alternatively , the retention clamp 50 may be omitted and a fastener 42 may be driven through a retention hole in the vertical element 36 of the “ l ” of the rail support , or through a retention hole in the pole 6 , or both , into one or both of the rails 44 . in yet another embodiment , the retention device may be a retention lip 31 that is at the top of the vertical element 36 and extends towards the pole 6 . the retention lip 31 could be any structure that extends towards pole 6 , such as a bent portion of the vertical element 36 , a separate welded element , or any suitable structure . as shown in fig1 , to secure a pair of rails in this embodiment , a first rail 44 is placed against the vertical element 36 , beneath the retention lip 31 , and a second rail 44 is placed between the first rail 44 and the pole 6 , and at least one fastener 42 is driven through both the first and second rails 44 , which lock them together . then the retention lip 31 , which is of sufficient length to engage the top of the first rail 44 , prevents these locked - together rails 44 from lifting out of the rail support 30 , 32 . to prevent the rails 44 from moving laterally within the rail support 30 , 32 , one or more fasteners 42 with a protruding head could be driven through the rails 44 on one side or both sides of the vertical element 36 or the pole 6 , wherein the protruding head would engage the vertical element 36 or the pole 6 to prevent significant lateral movement of the rails 44 . alternatively , the pole 6 and / or the vertical element 36 could have one or more holes 55 through which a single fastener 42 could be driven into the rails 44 to prevent both lateral and vertical movement of the rails . this latter embodiment could be used with or without the retention lip 31 . in some embodiments , the support bracket 2 could be used to support a pole 6 that holds scaffolding 47 . the support bracket 2 and pole 6 would have to be sized to accommodate the additional load of the scaffolding 47 and the worker ( s ) using the scaffolding 47 , as well as the live loads from those worker ( s ). a longer support bracket 2 may be used to spread the load over a greater length of the framing member 4 . alternatively , several smaller support brackets 2 may be used to support a single pole 6 . in some embodiments , the pole support 10 may be positioned farther away from the building than the guardrail supports described above , to accommodate the width of the scaffolding walking surface . the pole 6 may be long enough to insert into the entire length of such extended support bracket ( s ) 2 , although a shorter or longer length could be used . in a preferred embodiment , the scaffolding may be supported by scaffolding supports , a similar structure as the rail supports 30 , 32 attached to the pole 6 , but wider and shallower to accommodate the scaffolding walking surface , which may typically be 12 to 18 inches ( 30 . 5 to 45 . 74 cm ) wide . the scaffolding surface may be secured in a similar manner as the rails 44 of the above described guardrail system , with locking pins . alternatively , the scaffolding walking surfaces could be mounted on the scaffolding supports in a similar manner as existing scaffolding systems , with the scaffolding supports adapted to such mounting . the end of a scaffolding walking surface may be supported by a scaffolding end support , which can be on two separate poles 6 close together , each with an end support , or a single pole 6 with two end supports . the scaffolding support may be further adapted to attach to the building . a guardrail system as described above could be integrated into the pole 6 , with the pole 6 having rail supports 30 , 32 extending above the scaffolding walking surface . such guardrail system would typically be used to prevent falls from the scaffolding , and thus would be positioned on the outside of the scaffolding . alternatively , the scaffolding support pole could be a separate structure from the rail support pole . a scaffolding support pole could be placed into a support bracket , which bracket may have additional structure to attach to horizontal framing members to provide additional support . the scaffolding support pole may be substantially vertical and relatively close to the building , then have a cantilevered scaffolding support bracket incorporated into it that extends away from the building to hold the scaffolding walking surface . at the outer edge of the cantilevered scaffolding support bracket , another support bracket could be incorporated to hold a pole to support a guardrail system as described above . in the preferred embodiment , a support bracket 2 and pole 6 may be used with our without a scaffolding frame 60 . without the scaffolding frame 60 , the guardrail system works as described above . with the scaffolding frame 60 , the scaffolding frame 60 would be attached to the support bracket 2 and the pole 6 would be attached to the scaffolding frame 60 so that the support bracket 2 supports the pole 6 via the scaffolding frame 60 . as shown in fig1 , in the preferred embodiment , the scaffolding frame 60 comprises a vertical support bar 62 having a lower end 64 and an upper end 66 opposite the lower end 64 , a horizontal support 70 bar having a proximal end 72 and a distal end 74 opposite the proximal end 72 , and a diagonal support bar 80 having a first end 82 and a second end 84 opposite the first end 82 . the proximal end 72 of the horizontal support bar 70 is attached to the upper end 66 of the vertical support bar 62 . the first end 82 of the diagonal support bar 80 is attached to the distal end 74 of the horizontal support bar 70 , and the lower end 64 of the vertical support bar 62 is attached to the diagonal support bar 80 near the second end 84 . therefore , the vertical support bar 62 , the horizontal support bar 70 , and the diagonal support bar 80 generally define a triangular configuration . in the preferred embodiment , the proximal end 72 of the horizontal support bar 70 extends past the vertical support bar 62 , thereby terminating at a free terminal end 76 . attached to the horizontal support bar 70 in between the vertical support bar 62 and the free terminal end 76 of the horizontal support bar 70 may be another pole support insert 90 . the pole support insert 90 extends downwardly and perpendicularly from the horizontal support bar 70 and parallel to the vertical support bar 62 . the pole support insert 90 of the scaffolding frame 60 is substantially similar to the pole support insert 9 of the pole 6 so that either of the two can be inserted into the pole support 10 of the support bracket 2 . in the preferred embodiment , the second end 84 of the diagonal support bar 80 extends past the lower end 64 of the vertical support bar 62 . the second end 84 of the diagonal support bar 80 may comprise a bottom bracket 100 . in the preferred embodiment , the bottom bracket 100 comprises a first arm 102 and a second arm 104 opposite and parallel to the first arm 102 , the first and second arms 102 , 104 attached to the second end 84 of the diagonal support bar 80 with the first and second arms 102 , 104 defining a gap therebetween . the distance between the first and second arms 102 , 104 is sufficiently wide to receive the stud of the framing . each of the first and second arms 102 , 104 may define attachment holes 106 permitting the first and second arms 102 , 104 to be fastened to a stud inserted therebetween . in some embodiments , the first arm 102 and the second arm 104 each may comprise flanged endings 110 , 112 as shown in fig1 a . the flanged endings 110 , 112 may be substantially perpendicular to their respective first and second arms 102 , 104 and extend in opposite directions relative to each other . the flanged ends 110 , 112 may be sufficiently parallel to each other so as to be able to rest flush against a flat surface . the flanged ends 110 , 112 may also define attachment holes 114 . this configuration allows the second end 84 of the diagonal support bar 80 to attach to an appropriately sized stud if the stud fits in between the first and second arms 102 , 104 , or to attach to a particularly wide frame portion by fastening the flanged ends 110 , 112 flush against the frame . in an alternative embodiment , the bottom bracket 100 may have angled flanges 110 , 112 as shown in fig1 - 11 , adapted to fit corner framing members . in addition , as those in the art will appreciate , various pieces could be attached to the bottom bracket 100 shown in either fig1 or fig1 , to accommodate a variety of angles and shapes to fasten to various framing members . in some embodiments , as shown in fig1 b , the bottom bracket 100 may be a t - bar having a flat base 117 and a perpendicular brace 115 . the perpendicular brace 115 may have holes 114 . the flat base 117 may be pressed flat against the front of the frame with the perpendicular brace 115 against the side of the frame . the perpendicular brace 115 can be fastened to the frame with a screw or some other fastener . in another embodiment , the perpendicular brace 115 can be located in another position along the face of the flat base 117 to be adapted to fit a particular side of a framing member . for example , the perpendicular brace 115 could located on the edge of the face of the flat base 117 . for corner scaffolding , the length of the horizontal support bar 70 may have to be longer to accommodate the scaffolding 47 because the scaffolding frame 60 for a corner is at a 45 degree angle to the scaffolding frames 60 that are mounted 90 degrees relative to the walls of the building . a second pole support 120 may be attached to the distal end 74 of the horizontal support bar 70 and / or the first end 82 of the diagonal support bar 80 , perpendicular to the horizontal support bar 70 . the second pole support 120 defines a second cavity 122 having a second cavity dimension . thus , with the scaffolding frame 60 installed on the first pole support 10 of the support bracket 2 , the pole 6 can be installed on the second pole support 120 of the scaffolding frame 60 . as shown in fig1 , in the preferred embodiment , in which the pole 6 can be interchangeably inserted into the first pole support 10 ( or corner bracket 130 ) or the second pole support 120 , the pole support insert 9 of the pole 6 located below the pole stop 24 may comprise a stepped taper 17 to decrease an outer dimension of the pole support insert 9 in a stepwise manner moving towards the bottom end 7 of the pole 6 , thereby defining a larger region 19 of the pole support insert 9 having a first dimension above the step 17 and a smaller region 21 of the pole support insert 9 having a second dimension below the step 17 . the first dimension of the pole support insert 9 may be greater than the second dimension of the pole support insert 9 of the pole 6 . the first cavity 13 dimension is substantially the same as the second dimension of the pole support insert 9 , but smaller than the first dimension of the pole support insert 9 such that the larger region 19 of the pole support insert 9 cannot enter into the first cavity 13 of the first pole support 10 or the third cavity 142 of corner bracket 130 . the second cavity 122 dimension is substantially the same as the first dimension of the pole support insert 9 , and larger than the second dimension of the pole support insert 9 such that the larger region 19 of the pole support insert 9 and the smaller region 21 of the pole support insert 9 can pass through the second cavity 122 until the second pole support 120 abuts against the pole stop 24 . the reason for the varying dimensions is to accommodate the required heights for rail heights . for example , fall protection guardrails typically have a top rail at 42 inches above the flooring and a mid - rail 21 inches above the flooring , whether that flooring is for a building or scaffolding . if a first pole support 10 ( or corner bracket 130 discussed below ) is mounted on a framing member below the floor joist or rim board , the pole 6 has to be long enough to accommodate that distance so that the rails 44 are at the required height above the floor . thus , the smaller region 21 of the pole support insert 9 fits into the first cavity 13 of the first pole support 10 or the third cavity 142 of corner bracket 130 ( discussed below ), and stops when the larger region 19 of the pole support insert 9 abuts against the top of the first or third cavities 13 , 142 . in contrast , when the pole 6 is used for scaffolding , the horizontal support 70 defines the floor of the scaffolding 47 , so there is no need to compensate for floor joist height . thus the larger region 19 of the pole support insert 9 passes through the second cavity 122 until the top of the second pole support 120 abuts against the pole stop 24 , which puts the rail supports 30 , 32 at the proper heights for the scaffolding 47 . the guardrail system may further comprise a corner bracket 130 that can be substituted for the support bracket 2 when the guardrail is being installed at a corner of the framing 4 . in the preferred embodiment , the corner bracket 130 may comprise a third pole support 132 and an angled attachment 134 member having a first plate 136 operatively connected to a second plate 138 at substantially a right angle . the third pole support 132 may be connected to the angled attachment member 134 where the first plate 136 meets the second plate 138 . the first and second plates 136 , 138 each comprise a plurality of attachment holes 140 to fasten the corner bracket 130 to a corner of the framing , wherein the third pole support 132 comprises a third cavity 142 having a third cavity dimension that is substantially equal to the first cavity dimension of the first pole support 10 . therefore , in use , a support bracket 2 ( or a corner bracket 130 if at a corner of the framing ) may be fastened to a lower floor framing 4 lying horizontally on a ground , the lower floor framing 4 comprising a plurality of studs and a top plate . a pole support insert 9 or 90 may be inserted into the first pole support 10 , wherein the pole support insert 9 or 90 is operatively connected to a pole 6 such that when the pole support insert 9 or 90 is inserted into the first pole support 10 , a top end 5 of the pole 6 is at a desired height to create a guardrail that meets or exceeds government standards for temporary guardrail systems , wherein the pole 6 comprises at least one rail support 30 , 32 . the pole support insert 9 or 90 may be secured in the first pole support 10 . the lower floor framing 9 can then be erected placing the rail support 30 , 32 at the proper position . rails 49 may be installed into the at least one rail support 30 , 32 , whereby the guardrail is properly positioned on an upper floor area to protect construction workers working on the upper floor from falling . in addition , a support bracket 2 or a corner bracket 130 could be installed at any point in the construction process , and guardrails and / or scaffolding placed as needed . in some embodiments , in which a scaffolding is desired , the pole support insert 90 of a scaffolding frame 60 may be inserted into the first pole support 10 , the scaffolding frame comprising a second pole support 120 . the pole 6 is then inserted into the second pole support 120 to operatively connect to the pole support insert 90 . the foregoing description of the preferred embodiment of the invention has been presented for the purposes of illustration and description . it is not intended to be exhaustive or to limit the invention to the precise form disclosed . many modifications and variations are possible in light of the above teaching . it is intended that the scope of the invention not be limited by this detailed description , but by the claims and the equivalents to the claims appended hereto .
