Definitions

  • the invention relates to reflecting devices and particularly to an emergency reflecting device.
  • warning devices be provided that can be positioned on the roadway substantially in advance of a disabled vehicle to warn oncoming motorists.
  • Such devices have generally taken the form of burning flares and retro-reflective reflectors.
  • the most commonly used type of advance warning device was a system comprising a flat horizontal base meeting the roadway surface, and an upright housing perpendicular to the base, having located within it four reflex reflectors of approximately 3 inches in diameter, one reflector above the other,and each of these having a mating reflector opposingly disposed to provide reflectivity for motorists approaching disabled vehicles from either the front or the rear.
  • Recent federal legislation in the United States and Canada provides for an advance warning device comprising an equilateral triangle, having three sides of approximately two to 3 inches in width, and approximately 17m 22 inches in length.
  • the width of the individual legs is divided into two segments, one comprising red reflective material, and the other comprising orange fluorescent material; these jointly serving to provide for an internal triangle of orange fluorescent material, and a larger outer triangle of red reflective material.
  • the purpose for so dividing each of the triangles legs is to provide a reflective component for night time use, and a fluorescent component for daytime use.
  • the red reflective component is designed to utilize either spherical beads or cubed prism retroreflective elements
  • the orange fluorescent section is designed to convert ultra-violet radiant energy from the sun into a segment of the visible spectrum to delineate the device for daytime use.
  • the standards for the red reflective section and the orange fluorescent section are in all aspects, except for photometric quality, set forth in the applicable sections of the Society of Automotive Engineers standards.'The warning device must be so designed that it is capable of returning, at an observation angle of 0.2 and an entrance -angle of 80 candlepower per foot-candle incident upon the device I to be measured at 100 feet. At an observation angle of 1.5,'and a 0 entrance angle, the unit must yield 0.8 candlepower per incident foot-candle.
  • An object of this invention is to provide such a base and support combination in unison with a triangular Waming flare.
  • a further object of the invention is to provision for a convenient storage in a motor vehicle, considering fully the possibility that an automobile could sustain very severe frontal or rearend damage in a collision, and at that time a flare would be required. It is impractical to consider storage of these devices in the trunk area, since jamming or distortion of the sheet metal of the body could preclude access to the device.
  • Previous systems have generally comprised a collapsed structure far too large to conveniently store under automobile seats; especially in the case of compact and subcompact vehicles.
  • a further object of this invention is to provide a structure whereby storage beneath the seat is completely practical.
  • the invention describes a foldable emergency reflecting device comprising three members having reflective and fluorescent media thereon. Each member comprises two arms extending at an acute angle with respect to an apex. The ends of the arms are pivotally interconnected such that the members can be extended to form an emergency reflective triangle. One of the connections is releasable so that the device can be folded to form a compact triangle for storage comprising only one quarter of the area of the open triangle. Conventional means for manufacturing this type of device' yields a unit which will only collapse to approximately one half of its extended area.
  • the device also comprises a foldable base.
  • FIG. 1 is a perspective view of the device embodying the invention in expanded or unfolded condition.
  • FIG. 2 is a perspective view of the same in folded condition.
  • F IG. 3 is a fragmentary sectional view on an enlarged scale taken along the line 3-3 in FIG. 1.
  • FIG. 4 is a fragmentary sectional view on an enlarged scale taken along the line 4--4 in FIG. 1.
  • FIG. 5 is a fragmentary sectional view on an enlarged scale taken along the line 5-5 in FIG. .1.
  • FIGS. 6-8 are views showing the manner in which the device is folded to a compact condition for storage.
  • Each of the reflective members includes arms extending at an angle with respect to an apex, being 60 degrees.
  • the member 10 includes arms 15, 16 the member 11 includes arms 17, 18 and the member 12 includes arms 19, 20.
  • One arm 16 of member 10 is pivoted about an axis transverse to the plane of the arms to arm 17 of member 11 by a headed pivot pin 21 (FIG. 5) with a resilient washer 22 interposed between the arm 16 and the arm 17.
  • the other arm 18 of member 11 is pivoted to the arm 19 of member 12 by a headed pivot pin 23.
  • the other arm 20 of member 12 is interconnected with arm 15 of member 10 by a releasable connection formed by a pin 24 on arm 15 that extends into a metal cup 25 held on arm 20 by a pin 26.
  • the cup 25 has a resilient spring 27 therein which resiliently surrounds and grips a tapered surface 28 on the pin 24 so that the arm is releasably engaged in the arm but may be readily released without the use of tools.
  • a base is provided for the reflecting device and includes flat legs 30, 31, 32, 33 which are pivoted to one another by a pin 34.
  • Pin 34 holds a bracket 35 that is U-shaped and receives the end of the arm 18 of member 11.
  • the legs 30-33 can be folded into overlying relationship as shown in FIGS. 2, 7 and 8. Since the legs are in different planes, legs 30, 31 have downwardly extending projections 36, 37 which engage the ground and hold the device in level position when the legs are unfolded.
  • Each of the members 10, 11, 12 is provided with laterally extending integral projections 38 adjacent the apex thereof.
  • the projections 38 of the members 1 l, 12 extend into openings 39, 40 in the legs 31, 30, respectively when the device is in expanded position to provide rigidity to the triangle that is formed.
  • connection between the arms 15, 20 is broken by moving the arms 15, 20 laterally or transversely with respect to one another and then the member 12 is folded, as shown in broken lines in FIG. 6, until the leg 20 overlaps the leg 17. The member 10 is then folded downwardly until the arm 16 overlaps the arm 19 and the arm 15 overlaps the arm 18.
  • the legs can be folded into overlying relationship as shown in FIGS. 7 and 8.
  • the resultant structure is compact and easily stored but may be readily expanded to be used for emergency purposes. It is noted that the end of arm 19 is rounded to prevent interference with the leg 30 during folding.
  • a foldable emergency reflecting device comprising three members having reflective media thereon,
  • each member comprising a pair of arms rigidly connected to one another and extending at an acute angle to one another
  • each said means interconnecting said respective arms comprises a transverse pivot.
  • said reflective media comprises retro-reflective elements and fluorescent material.
  • each said member is made of substantially flat uniformly thick material having a width greater than its thickness.
  • leg which overlies the other legs includes a downwardly extending projection adapted to engage the ground when said legs are in extended position.
  • said legs comprise four legs pivotally interconnected by a single pivot, the axis of the pivot being transverse to the general plane of said members,
  • bracket being fixed to said second-mentioned member adjacent the pivot of the other leg 'of the second member to the one leg of said third member.
  • each member comprising a pair of arms rigidly connected to one another and extending at an acute angle to one another
  • transverse pivot means interconnecting the end of the arm of one of said members with the end of the arm of a second member
  • transverse pivot means interconnecting the end of the arm of the second member to one arm of the third member
  • said base comprising a plurality of laterally extending legs
  • said legs comprise four legs pivotally interconnected by a single pivot, the axis of the pivot being transverse to the general plane of said members,
  • bracket being fixed to said second-mentioned member adjacent the pivot of the other leg of the second member to the one leg of said third member
