Abstract
Abstract The device comprises a photometric head fixed on a movable stand. Held to the photometric head is a system for orienting the device with respect to the longitudinal axis of the transport vehicle. The orienting system has two reflecting faces and is made as a polyhedral optically transparent prism, or as two mirrors, one of the faces of the prism or one of the mirror being provided with a rectangular graticule, one cluster of lines thereof being arranged along the optical axis of the photometric head. While in operation, the device is positioned opposite the transport vehicle, whereupon a portion of the vehicle is selected, that is arranged either lengthwise or crosswise the longitudinal axis of the vehicle, and the image of the portion is brought in alignment with one of the lines of the rectangular graticule of the orienting system.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
268 words
A method of diagnosing the head lamps of transport vehicles, the method comprising the steps of: positioning a photometric head in front of the transport vehicle against the head lamps thereof; orienting the optical axis of the photometric head to be aligned with the axis of the head lamps and to be set in parallel with the longitudinal axis of the transport vehicles; providing at least two reflecting faces for orienting the optical axis of the photometric head, one of the two reflecting faces being formed with a rectangular graticule, the rectangular graticule being oriented on the photometric head so that the longitudinal cluster of lines of the rectangular graticule is disposed parallel to the vertical plane passing through the optical axis of the photometric head, the other cluster of lines of the rectangular graticule transversing the directions of the optical axis of the photometric head, the other one of two reflecting faces receiving the image of a selected portion of the transport vehicle and reflecting the image onto the other face formed with the rectangular graticule, the selected portion of the transport vehicle having an edge which is perpendicular to the longitudinal axis of the transport vehicle; turning the photometric head until the image of the selected portion of the transport vehicle reflected onto the face formed with the rectangular graticule becomes aligned with the transverse cluster of lines of the rectangular graticule so that the optical axis of the photometric head is set with the longitudinal axis of the transport vehicle; switching on the head lamp; and observing and checking the setting of the head lamp.
Claim 2
Independent Claim
268 words
A method of diagnosing the head lamps of transport vehicles, the method comprising the steps of: positioning a photometric head in front of the transport vehicle against the head lamps thereof; orienting the optical axis of the photometric head to be aligned with the axis of the head lamps and to be set in parallel with the longitudinal axis of the transport vehicles; providing at least two reflecting faces for orienting the optical axis of the photometric head, one of the two reflecting faces being formed with a rectangular graticule, the rectangular graticule being oriented on the photometric head so that the longitudinal cluster of lines of the rectangular graticule is disposed parallel to the vertical plane passing through the optical axis of the photometric head, the other cluster of lines of the rectangular graticule transversing the directions of the optical axis of the photometric head, the other one of two reflecting faces receiving the image of a selected portion of the transport vehicle and reflecting the image onto the other face formed with the rectangular graticule, the selected portion of the transport vehicle having an edge which is perpendicular to the longitudinal axis of the transport vehicle; turning the photometric head until the image of the selected portion of the transport vehicle reflected onto the face formed with the rectangular graticule becomes aligned with the transverse cluster of lines of the rectangular graticule so that the optical axis of the photometric head is set with the longitudinal axis of the transport vehicle; switching on the head lamp; and observing and checking the setting of the head lamp.
Claim 3
Independent Claim
273 words
A device for diagnosing the head lamps of a transport vehicle, said device comprising: a photometric head being positioned in front of the transport vehicle against the head lamps thereof; means for orienting the optical axis of said photometric head to be aligned with the axis of the head lamps and to be set in parallel with the longitudinal axis of said transport vehicle, said orienting means having at least two reflecting faces, one of said at least two reflecting faces being formed with a rectangular graticule, said rectangular graticule being oriented on said photometric head so that the longitudinal cluster of lines of said rectangular graticule is disposed parallel to the vertical plane passing through said optical axis of said photometric head, the other cluster of lines of said rectangular transversing the direction of the optical axis of said photometric head, the other one of said at least two reflecting faces being adapted to receive the image of a selected portion of said transport vehicle and to reflect said image onto the other face formed with the rectangular graticule, said selected portion of said transport vehicle having an edge which is perpendicular to the longitudinal axis of said transport vehicle; said photometic head being turned until the image of said selected portion of said transport vehicles reflected onto the face formed with the rectangular graticule becomes aligned with the transverse cluster of lines of said rectangular graticule so that the optical axis of said photometric head is set parallel with the longitudinal axis of the transport vehicle; the head lamps being switched on; and the head lamp setting being observed and checked.
Claim 4
Independent Claim
273 words
A device for diagnosing the head lamps of a transport vehicle, said device comprising: a photometric head being positioned in front of the transport vehicle against the head lamps thereof; means for orienting the optical axis of said photometric head to be aligned with the axis of the head lamps and to be set in parallel with the longitudinal axis of said transport vehicle, said orienting means having at least two reflecting faces, one of said at least two reflecting faces being formed with a rectangular graticule, said rectangular graticule being oriented on said photometric head so that the longitudinal cluster of lines of said rectangular graticule is disposed parallel to the vertical plane passing through said optical axis of said photometric head, the other cluster of lines of said rectangular transversing the direction of the optical axis of said photometric head, the other one of said at least two reflecting faces being adapted to receive the image of a selected portion of said transport vehicle and to reflect said image onto the other face formed with the rectangular graticule, said selected portion of said transport vehicle having an edge which is perpendicular to the longitudinal axis of said transport vehicle; said photometic head being turned until the image of said selected portion of said transport vehicles reflected onto the face formed with the rectangular graticule becomes aligned with the transverse cluster of lines of said rectangular graticule so that the optical axis of said photometric head is set parallel with the longitudinal axis of the transport vehicle; the head lamps being switched on; and the head lamp setting being observed and checked.
Claim 5
Dependent Claim
98 words
A device for diagnosing the head lamps of transport vehicles as claimed in claim 2, wherein said reflecting faces are formed as the faces of a polyhedral optically transparent prism, said prism having an axis of rotation parallel to said optical axis of said photometric head one of said faces being disposed with said rectangular graticule so that the longitudinal clusteR of lines of said rectangular graticule is parallel with the axis of rotation of said prism and the transverse cluster of lines of said rectangular graticule which is perpendicular to the axis of rotation of said prism.
