Abstract
Abstract This invention relates to a safety device, and in particular, to a reflector structure of high visibility for use in connection with vehicles such as motorcycles, bicycles, etc., the structure comprising a hollow cylinder whose outer surface is covered with a highly reflective sheeting material or highly reflective paint, and a means for easily clamping the cylinder to the vehicle. The device is provided with means for allowing the reflector to be used as a stationary light reflecting signal when the vehicle operator encounters trouble on the road.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
127 words
A safety reflector device for use in conjunction with moving vehicles, comprising a hollow cylinder, means for reflecting light of a frequency to which the eye is most sensitive under high intensity ambient light conditions, a second means for reflecting light of a frequency to which the eye is most sensitive to under low intensity light conditions, the two reflecting means being fastened respectively to the cylinder in alternate fields on the outer surface of the said cylinder in a checkerboard pattern and clamping means for fastening the said reflector device to a vehicle, one of said reflecting means reflects only white light of a frequency of 5,000 Angstrom units, and said second means for reflecting light reflects only light of a frequency of 5,500 Angstrom units.
Claim 2
Dependent Claim
127 words
A safety reflector device for use in conjunction with moving vehicles, comprising a hollow cylinder, means for reflecting light of a frequency to which the eye is most sensitive under high intensity ambient light conditions, a second means for reflecting light of a frequency to which the eye is most sensitive to under low intensity light conditions, the two reflecting means being fastened respectively to the cylinder in alternate fields on the outer surface of the said cylinder in a checkerboard pattern and clamping means for fastening the said reflector device to a vehicle, one of said reflecting means reflects only white light of a frequency of 5,000 Angstrom units, and said second means for reflecting light reflects only light of a frequency of 5,500 Angstrom units.
Claim 3
Dependent Claim
28 words
In a safety reflector as in claim 1 in which the diameter of the said cylinder is 2 inches minimum and its length a minimum of 9 inches.
Claim 4
Dependent Claim
58 words
In a safety reflector device as in claim 1 a cap for closing one end of the said cylinder, the said cap being in disc form and provided with means for holding the said disc to the end of the said cylinder and means for limiting the travel of the said disc into the end of the cylinder.
Claim 5
Dependent Claim
32 words
In a safety reflector as in claim 3 in which the said disc is provided with a spike extending outwardly and normal to one of the flat faces of the said disc.
Claim 6
Dependent Claim
53 words
In a safety reflector as in claim 4 in which the said disc is provided with means to allow a portion of the disc to be inseRted a predetermined distance into one end of the said cylinder with either one of its two faces disposed outward of the end of the said cylinder.
Claim 7
Dependent Claim
72 words
In a safety reflector as in claim 5 in which the said disc is constructed with a flange at the center of its circular periphery in which the outer dimension of the flange is equal to the outer dimension of the cylinder and in which the outer diameter of the remaining portion of the disc is of a dimension to provide a holding fit with the inside diameter of the said cylinder.
Claim 8
Dependent Claim
40 words
In a safety reflector as in claim 6 in which the reflecting material has a reflection factor of at least 95 percent and has a color which lies in the range of frequencies between 5,000 and 5, 500 Angstrom units.
