referring now to fig1 to 3 , we see several views of the preferred embodiment of a sports training device 10 as described hereinabove . as shown , the device comprises at least one and , preferrably , two perpendicularly suspended pendular members 12 which are mounted onto the outermost extremity frame means 14 and adapted to follow an oscillatory path when set in motion . as shown schematically in fig3 frame means itself 14 is basically in the form of an inverted , skewed , three - sided pyramid which is adapted to be attached to a wall 15 . the angular relationships shown are illustrated by way of example and are not considered to be critical . similarly the materials of construction are not critical , the only limitation being that they be strong enough to support the structure and light enough to allow easy adjustment . there are numerous low cost steel and aluminum alloys which meet these requirements and any of them can be used . the inverted triangular base of the frame pyramid is formed by the cooperation of a pair of outwardly disposed , upper struts 16 with a horizontal upper mounting brace strut 18 set along wall 15 and to which their inner ends are attached . struts 16 join together at junction point 20 to form the apex of the base triangle . defining the sides of the pyramid are a pair of angled side struts 22 which are also disposed along but not attached to wall 15 and diagonal front strut 24 which is inwardly directed from base apex 20 , all of which join together at the inverted peak 26 of the pyramid . parallel to brace strut 18 attached to the side struts 22 at an intermediate point approximately two thirds of the distance between the pyramid base and peak 26 is a lower horizontal mounting brace 28 . as shown most clearly in fig3 mounting braces 18 and 28 both fit into vertical wall mount means 30 which are bolted or otherwise attached to wall 15 and which is in the form of a complimentary pair of inwardly opening parallel , vertical , z - shaped channels 31 , said openings forming a pair of vertical gaps 32 into which the ends of these braces fit . as shown in fig4 the ends of the braces are covered with a polyethylene or other slideable bearing surface material 33 which allows frame means 14 to be moved freely up and down within the vertical gaps 32 in channel structure 31 . locking of frame means 14 within mounting means 30 is handled with adjustment means 34 which is shown in more detail in fig5 . as shown , this is provided at inverted peak point 26 where the two side struts 22 and front strut 28 join together to form the pyramid structure of frame 14 . adjustment means 34 comprises a pressure pad 36 threadably mounted with stud 38 through a more or less centrally positioned hole 39 in mounting plate 40 and having a handle 42 on outermost end of stud 38 . mounting plate 40 is physically attached to frame means 14 so that when pressure pad 36 is caused to press against wall 15 by the clockwise rotation of handle 42 , it is forced to move relatively away from said wall causing mounting plate 40 and therefore frame 14 to rotate slightly outwardly . this rotation acts to cause lower support brace 28 to move outwardly and upper support brace 18 to move inwardly so that they will bear against the front and rear surfaces of the gaps 32 in channels 31 . the bearing pressure developed by this rotation of the braces provides enough frictional resistance to slidingly lock frame 14 firmly in place within mount means 30 at any vertical position where it is set . counterclockwise rotation of handle 42 reverses the process so that said bearing pressure is relieved . when this is done , frame 14 can then be slid up and down within mount means 30 to be repositioned at another location . the active portion of the subject invention is attached to frame means 14 at base apex point 20 , the outermost point of frame 14 . as described hereinabove and as shown in fig1 and 2 , swinging pendulum means 44 , having in the preferred embodiment two angularly adjustable pendular members 12 hangs unobstructedly and pivotally therefrom . each of members 12 is , in the preferred embodiment , made from a circular tube . this is primarily for the purpose of preventing possible injury to the user by eliminating any sharp edges which might come in contact with the user &# 39 ; s body , particularly the head . the potential for injury is further reduced by placing over the lower , outer end of each member 12 a resilient pad 46 . for purposes of illustration , the assembly is vertically adjusted so that the user &# 39 ; s eyes will be at the point marked with an &# 34 ; x &# 34 ; in fig1 . when this is done , his head will be within the line of travel of the end pads 46 and the exercise will depend as much on visual acuity as on physical dexterity . the particular pendular swinging motion which is established is set up by the cooperation of an upper pivot means 48 , which is attached to base apex 20 of frame means 14 with a lower pivot means 49 to which both pendular members 12 are attached . referring now to fig6 and 7 , we see a side and end view of upper pivot means 48 . as shown , it comprises a horizontally disposed base mounting plate 50 which is attached by being welded or bolted to frame means 14 at apex point 20 . fitted onto base plate 50 are a pair of downwardly disposed , spaced apart parallel yoke members 52 perpendicular to the axis of symetry of said frame and having threadable ends 53 and being held onto base plate 50 by adjustment nuts 54 which are , as shown , placed above and below plate 50 on ends 53 to permit adjustable alignment thereof . machined into the bottommost portion of the inner side , of each of yoke members 52 is curved depression 56 into which the downwardly disposed center portion of curved axle 58 is set . slideably mounted onto axle 58 between said yoke members is the upper end 59 of vertically disposed main pivot member 60 on to which lower pivot means 49 is attached . set within end 59 is ball - bearing unit 62 through which axle 58 passes , which allows pivot member 60 to readily slide back and forth on said axle in and out relative to frame 14 . one reason for the sliding motion is to allow the automatic repositioning of pivot member 60 in the event that it is dislodged from its normal position , as for example , by reason of the obstruction of the free swing of pendulum means 44 through disturbances such as any impacts with the user that may occur with the end portions of pendular members 12 . in this manner , considerable , lateral forgiveness is provided so that impact with the user by the padded end portions 46 would not cause injury to the user and allow easy repositioning of the unit in its basic , normal operating position . as will herein be explained below , this sliding motion also permit the establishment of complex pendular movement patterns to provide a more rigorous exercise scheme for this user . it will be noted , as shown in fig7 that curved axle 58 is not welded or otherwise firmly fixed to yoke members 52 . this allows the easy removal of the pivot and pendulum assemblies from the yoke members to allow changing the period of pendulum oscillation by substituting alternate assemblies containing pendular members which could be shorter , longer , heavier or lighter than those currently attached . at the lower end 61 of main pivot member 60 is lower pivot point 49 . this is to adjust the angular relationship of pendular members 12 and is shown in detail in fig8 . machined into lower end 61 is a more or less symetrical cross - shaped slot 64 . a pivot pin 66 is provided which is threaded at one end for engagement by wing nut 68 , so that upon assembly , pin 66 will extend through mating apertures 70 and 71 which are defined in anchor plates 72 and 73 said anchor plates being positioned on the upper ends of each of the two pendular members 12 . as shown in fig8 pivot pin 66 also extends through the vertical portion of cross - shaped slot 64 and is sized with respect to the it so that when loosened , pivot pin 66 may travel relatively vertically within the slot as shown by the double - ended arrow &# 34 ; a &# 34 ; in fig8 . angular positioning of pendular members 12 is accomplished by a set of tracking pins 74 , one of which protrudes from the opposing surfaces of anchor plates 72 and 73 . these are set to move laterally within the horizontal portion of cross - shaped slot 64 shown by double - ended arrow &# 34 ; b &# 34 ;. accordingly , when the angular relationship of pendular members 12 with respect to each other is to be altered , wing nut 68 is merely loosened and pin 66 moved upwardly or downwardly within the vertical portion of slot 64 . this causes tracking pins 74 to move sideways within the horizontal portion of slot 64 relatively toward and away from each other , depending upon whether the adjustment to be made is to be less or more angular . the geometric configuration of these parts will accordingly ensure that the main pivot member 60 , bisects whatever angle found between the two pendular members 12 is established to set up a completely symetrical apparatus . thus , relatively easy adjustment of all the main aspects of this apparatus to meet the particular exercise needs of any user is possible . with this understanding of how the subject invention is constructed , let us now turn to a consideration of how it operates . after the relative vertical position and angular reposition and angular relationship of the two pendular members 12 has been adjusted , as hereinabove described , and the user has set training device 10 to the position desired , he then merely grasps one of pendular members 12 and pulls it toward him to start pendulum means 34 swinging from side to side . if a purely lateral force , that is there is no forwardly directed component of motion is provided the pendulum will simply swing back and forth in an oscillatory plainar motion with main pivot member remaining at the lowermost point on axle 58 most of the time . the amplitude and period decay characteristics of this motion will be set by the pendular length and mass according to well - established principles of physics and the frictional losses in bearing member 62 . as each one of the padded ends 46 passes by the user , he must first see it and then dance , bob and weave , duck , or in some other way avoid it so that he will not be struck thus , accomplishing the stated objective of improving the user &# 39 ; s peripheral vision , footwork and upper body agility . if , in starting the pendular members moving , the user imparts forward as well as a sidewise , lateral thrust , the pivot member 60 will be caused to move back and forth on axle 58 as well as from side to side . when this is done the ends of the pendular members 12 begin to describe more complex and irregular patterns , such as a figure 8 , thus , considerably increasing the difficulty of the exercise and providing a greater potential benefit to the user . thus it can be seen that the objectives stated above , have been met in a simple easy - to - use sports training device . it is to be understood that the foregoing suggested apparatus as exemplified by the figures , is intended to be illustrative of a preferred embodiment of the subject invention and that many options will readily occur to those skilled in the art without departure from the spirit or the scope of principals of the subject invention as defined in the attached claims .
