fig1 is an isometric drawing of a safety device 10 according to this invention . the safety device 10 comprises a rigid standard 12 extending from a mount 14 . fig1 shows the standard 12 resembling a pennant 16 , although the standard 12 may have any shape . the mount 14 preferably includes a permanent magnet 18 , and the permanent magnet 18 allows the mount 14 to be attached to any magnetizable surface ( such as a vehicle 20 ). the standard 12 preferably has a highly - visible surface color 22 ( such as bright orange , bright yellow , etc . ), and the standard 12 alerts a person to be aware while in the vicinity of the standard 12 . when the mount 14 is magnetically attached to the vehicle 20 , the standard 12 alerts an approaching motorist , or pedestrian , to be aware while in the vicinity of the vehicle 20 . fig2 and 3 are schematics showing additional details of the safety device 10 shown in fig1 . fig2 is an orthographic view of the safety device 10 , while fig3 is a partial , enlarged view of a portion of the safety device 10 . although the mount 14 resembles a generally “ c ”- shaped bracket 24 , the mount 14 may have any shape to suit the application . the bracket 24 has at least one support member 26 extending from a body 28 . an upper support member 30 and a lower support member 32 , for example , cantilever from the body 28 . the upper support member 30 has an elongate shape defining an upper longitudinal axis l u — l u ( shown as reference numeral 34 ). the upper support member 30 has a hole , or an aperture 36 , approximate a distal end 38 . the aperture 36 is preferably aligned along the upper longitudinal axis l u — l u . the lower support member 32 , likewise , has an aperture 40 approximate a distal end 42 , and the aperture 40 is preferably aligned along a lower longitudinal axis l l — l l ( shown as reference numeral 44 ). the standard 12 has an upper pin 46 and a lower pin 48 at a common end 50 of the standard 12 . the upper pin 46 and the lower pin 48 are preferably aligned along a pivot axis l p — l p ( shown as reference numeral 52 ). the upper pin 46 inserts up into the aperture 36 in the upper support member 30 , while the lower pin 48 inserts down into the aperture 40 in the lower support member 32 . the upper pin 46 and the lower pin 48 each rotate within their respective apertures 36 , 40 , thus acting as trunnions to allow the standard 12 to pivot about the pivot axis l p — l p . as fig3 best shows , the lower support member 32 includes at least one channel . a first channel 54 , for example , is approximately perpendicularly oriented to the longitudinal axis l l — l l and radially extends from an outer edge 56 of the aperture 40 to an outer edge 58 of the distal end 42 . a second channel 60 is approximately oriented along the longitudinal axis l l — l l and radially extends from the outer edge 56 of the aperture 40 to the outer edge 58 of the distal end 42 . a third channel 62 is oriented between the first channel 54 and the second channel 60 , and the third channel 62 radially extends from the outer edge 56 of the aperture 40 to the outer edge 58 of the distal end 42 . because the first channel 54 is approximately perpendicularly oriented ( e . g ., 90 °) to the longitudinal axis l l — l l , and because the second channel 60 is approximately oriented along the longitudinal axis l l — l l ( e . g ., 0 °), the third channel 62 is preferably oriented between about zero degrees ( 0 °) and about ninety degrees ( 90 °), more preferably between about fifteen degrees ( 15 °) and about seventy five degrees ( 75 °), and most preferably between about thirty degrees ( 30 °) and about sixty degrees ( 60 °). the standard reposes within either channel . each channel 54 , 60 , and 62 has a width sized to accept a thickness 64 of an end portion 66 of the standard 12 . each channel 54 , 60 , and 62 also has a depth sufficient to retain the end portion 66 within the channel . as the standard 12 pivots about the pivot axis l p — l p ( shown as reference numeral 52 ), the end portion 66 of the standard 12 falls into either channel 54 , 60 , or 62 . each channel 54 , 60 , or 62 thus retains the standard 12 in one of three positions : the first channel 54 retains the standard 12 in a position approximately perpendicular to the lower support member 32 , the second channel 60 retains the standard 12 in a position approximately along the lower support member 32 , and the third channel 62 retains the standard 12 in an intermediate position . these three channels 54 , 60 , and 62 allow the standard 12 to be oriented to improve visibility of the standard 12 . if a user desires to change the orientation of the standard 12 , the upper support member 30 and the lower support member 32 are spaced such that the standard 12 may be lifted out of the channel ( either 54 , 60 , or 62 ) and pivoted to another channel . when the standard 12 is lifted from the channel ( either 54 , 60 or 62 ), the lower pin 48 preferably has a length sufficient to retain the lower pin 48 within the aperture 40 in the lower support member 32 . when the standard 12 drops into either channel ( 54 , 60 , or 62 ), the upper pin 46 , likewise , preferably has a length sufficient to retain the upper pin 46 in the aperture 36 in the upper support member 30 . the standard 12 may thus be lifted from engagement with one channel ( 54 , 60 , or 62 ) and pivoted to engage another channel . not only do the channels 54 , 60 , and 62 orient the standard 12 , but the channels also reduce damage . although the channels have a depth sufficient to retain the end portion 66 , the channels also provide a folding feature during impact . if a passing motorist impacts the standard 12 , the force of the impact snaps the end portion 66 from the channel . the standard 12 is thus able to pivot about the pivot axis l p — l p ( shown as reference numeral 52 ). as the standard 12 pivots , impact energy is absorbed and damage is reduced . fig4 is a schematic showing additional details of the mount 14 shown in fig1 . fig4 is a partial , exploded view of the mount 14 and the permanent magnet 18 . the body 28 has a channel 68 sized to accept the permanent magnet 18 . the channel 68 is preferably sized such that the permanent magnet 18 frictionally engages , or “ press fits ” into , the channel 68 . the channel 68 , for example , may include one or more protruding posts 70 spaced along the channel 68 . each post 70 outwardly protrudes from a bottom surface 72 of the channel 68 . each post 70 inserts into and through a corresponding hole 74 in the permanent magnet 18 . as fig4 a best shows , each post 70 has a cone - shaped top portion 76 , a left finger halve 82 , and a right finger halve 84 . an open slot 86 separates the left finger halve 82 from the right finger halve 84 . because the conical top portion 76 has a major diameter greater than the corresponding hole 74 , the finger halves 82 and 84 squeeze together as the cone - shaped top portion 76 inserts into and through the hole 74 . when the cone - shaped top portion 76 emerges through the hole 74 , the finger halves 82 and 84 expand and the conical top portion 76 retains the permanent magnet 18 in the channel 68 . the channel 68 alternatively or additionally may include a inwardly protruding lip or flange along at least one side of the channel 68 . the permanent magnet 18 would insert into an open end of the channel 68 and slide along the channel 68 . the flange helps retain the permanent magnet 18 in the channel 68 . the channel 68 is preferably sized such that the permanent magnet 18 frictionally slides along the channel 68 . the permanent magnet 18 , however , may alternative or additionally be secured to the mount 14 using any other securement . tabs , tangs , adhesives , threaded fasteners , welds , and / or any other means of securing the permanent magnet 18 are suitable . once the standard 12 is deployed , the standard 12 alerts others . if , for example , the standard 12 has a highly - visible surface color ( shown as reference numeral 22 in fig1 ), the standard 12 alerts a person to be aware while in the vicinity of the standard 12 . when the mount 14 is magnetically attached to the vehicle ( shown as reference numeral 20 in fig1 ), the standard 12 alerts an approaching motorist , or pedestrian , to be aware while in the vicinity of the vehicle . the standard 12 , however , could alternatively be produced with a logo or trademark to signify support or loyalty for a group , such as a sporting team . the standard 12 could be imprinted with a photograph , picture , icon , logo , trademark , cartoon character , scene , word , phrase , or number ( s ). the standard 12 could then be marketed to sporting / cultural / artistic fans or participants . fig5 is a schematic showing an alternative embodiment of this invention . fig5 shows an extensible safety device 88 . this safety device 88 comprises a rigid standard 90 extending from a mount 92 . the standard 90 , however , comprises at least a first section 94 moving in relation to a second section 96 . the first section 94 moves to extend a length l ( shown as reference numeral 98 ) of the standard 90 . the standard 90 may even comprise more sections moving in relation to the first 94 and second 96 sections to further extend the length l of the standard 90 . the term “ moving ” means at least one of the sections 94 and 96 slide , pull , translate , extend , screw , spin , thread , push , and / or raise to increase the length l of the standard 90 . fig5 , for example , shows the section 94 sliding to increase the length l of the standard 90 . the first section 94 is a rigid panel 100 that slides along a track 102 . the track 102 outwardly extends from a top 104 and a bottom 106 of the second section 94 , the second section also being shown as a panel 108 . the track 102 has a track channel 110 extending along at least a portion of the bottom 106 of the second panel 108 . the track channel 110 preferably has a width slightly larger than a thickness of the first panel 100 , thus allowing a bottom edge 112 of the first panel 100 to insert into , and slide along , the track channel 110 . the extensible standard 90 may have as many sections , in any length , to suit the application . the panels 100 and 108 , for example , may each have a length of about twelve inches ( 12 in .) and a height of eight inches ( 8 in . ), thus providing almost twenty four inches ( 24 in .) of length l . the panels may have smaller dimensions or larger dimensions to suit the application . the standard 90 may also have more or less than the two panels shown . fig5 also shows additional details of the safety device 88 . while the standard 90 is rigid , the standard 90 may be constructed of any polymer material and / or metal material that permits the extensible feature of the invention . the standard 90 preferably has a highly - visible surface color 114 , and the standard 90 may include reflective material 116 to enhance visibility of the standard 90 . the standard 90 may extend from the mount 92 , and the mount 92 may include a permanent magnet ( not shown ). the standard 90 may be supported by at least one support member 118 extending from the mount 92 to the standard 90 . the at least one support member 118 may have a swivel feature ( not shown ) at either end of the support member 118 . this swiveling feature allows the support member 118 to swivel at the mount 92 and / or the standard 90 , thus permitting the standard 90 to be oriented for visibility . fig6 is a schematic showing yet another alternative embodiment of this invention . fig6 shows a telescopic safety device 120 to enhance visibility . this safety device 120 comprises a rigid standard 122 extending from the mount 92 . here the standard 122 has an inner section 124 and an outer section 126 . the outer section 126 has a tubular cross - section 128 , and the inner section 124 is sized such that the inner section 124 slides within the outer section 126 . although only one inner 124 and outer 126 section is shown , the telescoping standard 122 may have successive pairs of inner and outer sections . the successive pairs of inner and outer sections are sized such that an inner section of one pair is also the outer section of an adjoining pair ( e . g ., similar to a telescopic antenna ). while the standard 122 is rigid , the standard 122 may be constructed of any polymer material and / or metal material that permits the extensible feature of the invention . the standard 122 preferably has the highly - visible surface color ( such as that shown as reference numeral 22 in fig1 ), and the standard 122 may include reflective material to enhance visibility of the standard 122 . the standard 122 may extend from the mount 92 , and the mount 92 may include a permanent magnet . the mount 92 may include the swivel feature allowing the standard 122 to be oriented for visibility . fig6 shows the telescopic standard 122 having an oval tubular cross - section , however , any tubular cross - section is suitable for this invention . while the present invention has been described with respect to various features , aspects , and embodiments , those skilled and unskilled in the art will recognize the invention is not so limited . other variations , modifications , and alternative embodiments may be made without departing from the spirit and scope of the present invention .
