Abstract

Abstract Two headlight frames are mounted on the vehicle body front to be tilted about their lower peripheries and are usually preloaded by a spring assembly to be limitedly tilted. A manually operable lever accessible to an operator is movable to and is held in the selected one of multiple operating positions. The manual operating effort applied to the lever is transferred through a linkage including cables or rods and pivotal levers to the headlight frame to maintain it in a certain tilted position corresponding to the selected position of the manually operable lever.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 299 words
Headlight tilting control device of a motor vehicle comprising, in combination: two headlight frames arranged on the opposite lateral ends of the vehicle body front portion, each said frame having one end pivotally mounted on a fixed part of the vehicle body and the other end constantly loaded by spring means to maintain said headlight frame in a predetermined tilted position; tilt adjusting means for providing tilting movement of said headlight frames against the load of said spring means; manually operating means located on a fixed part of the vehicle body accessible to an operator comprising a manually moveable lever pivotally mounted on a fixed part of the vehicle body, a positioning plate having a plurality of grooves in any of which said manually moveable lever is received and held in position upon pivotal movement of said lever; and intermediate linkage means linked between said tilt adjusting means and said manually operating means for transferring the manually operating effort applied to a positioning plate having a plurality of grooves in any of which said manually moveable lever is received and held in position upon pivotal movement of the manually moveable lever, said intermediate linkage means comprising a linkage frame located intermediate of said two headlight frames and extending substantially in parallel with the headlight frames, a moveable plate mounted on said linkage frame to be moveable relative thereto, two oppositely directed L-shaped levers pivotally carried on said linkage frame, each said L-shaped lever having one end connected with said moveable plate and an opposite end, two connecting cables each interconnecting said opposite end of the angled arm and said opposite end of the L-shaped lever, and a drive transferring cable having one end connected with said moveable plate and the other end length-adjustably connected with said manually moveable lever.
Claim 2
Dependent Claim 299 words
Headlight tilting control device of a motor vehicle comprising, in combination: two headlight frames arranged on the opposite lateral ends of the vehicle body front portion, each said frame having one end pivotally mounted on a fixed part of the vehicle body and the other end constantly loaded by spring means to maintain said headlight frame in a predetermined tilted position; tilt adjusting means for providing tilting movement of said headlight frames against the load of said spring means; manually operating means located on a fixed part of the vehicle body accessible to an operator comprising a manually moveable lever pivotally mounted on a fixed part of the vehicle body, a positioning plate having a plurality of grooves in any of which said manually moveable lever is received and held in position upon pivotal movement of said lever; and intermediate linkage means linked between said tilt adjusting means and said manually operating means for transferring the manually operating effort applied to a positioning plate having a plurality of grooves in any of which said manually moveable lever is received and held in position upon pivotal movement of the manually moveable lever, said intermediate linkage means comprising a linkage frame located intermediate of said two headlight frames and extending substantially in parallel with the headlight frames, a moveable plate mounted on said linkage frame to be moveable relative thereto, two oppositely directed L-shaped levers pivotally carried on said linkage frame, each said L-shaped lever having one end connected with said moveable plate and an opposite end, two connecting cables each interconnecting said opposite end of the angled arm and said opposite end of the L-shaped lever, and a drive transferring cable having one end connected with said moveable plate and the other end length-adjustably connected with said manually moveable lever.
Claim 3
Dependent Claim 294 words
Headlight tilting control device of a motor vehicle comprising, in combination: two headlight frames arranged on the opposite lateral ends of the vehicle body front portion, each said frame having one end pivotally mounted on a fixed part of the vehicle body and the other end constantly loaded by spring means to maintain said headlight frame in a predetermined tilted position; tilt adjusting means for providing tilting movement of said headlight frames against the load of said spring means; manually operating means located on a fixed part of the vehicle body accessible to an operator, comprising a manually moveable lever pivotally mounted on a fixed part of the vehicle body, a positioning plate having a plurality of grooves in any of which said manually moveable lever is received and held in position upon pivotal movement of the manually moveable lever, and intermediate linkage means linked between said tilt adjusting means and said manually operating means for transferring the manually operating effort applied to said manually operating means to said tilt adjusting means, comprising a linkage frame located intermediate of said two headlight frames and extending substantially in parallel with the headlight frames, a vertical lever pivotally carried on said linkage frame about a pivot axis, an upwardly bent connecting rod interconnecting said opposite end of one of said angled arms and an upper portion of said vertical lever at a certain distance from the pivot axis, a downwardly bent connecting rod connecting said opposite end of the other angled arm and a lower portion of said vertical lever at a distance equal to said certain distance from the pivot axis, and a drive transferring cable having one end length-adjustably connected with said vertical lever and the other end connected with said manually moveable lever.
Claim 4
Dependent Claim 294 words
Headlight tilting control device of a motor vehicle comprising, in combination: two headlight frames arranged on the opposite lateral ends of the vehicle body front portion, each said frame having one end pivotally mounted on a fixed part of the vehicle body and the other end constantly loaded by spring means to maintain said headlight frame in a predetermined tilted position; tilt adjusting means for providing tilting movement of said headlight frames against the load of said spring means; manually operating means located on a fixed part of the vehicle body accessible to an operator, comprising a manually moveable lever pivotally mounted on a fixed part of the vehicle body, a positioning plate having a plurality of grooves in any of which said manually moveable lever is received and held in position upon pivotal movement of the manually moveable lever, and intermediate linkage means linked between said tilt adjusting means and said manually operating means for transferring the manually operating effort applied to said manually operating means to said tilt adjusting means, comprising a linkage frame located intermediate of said two headlight frames and extending substantially in parallel with the headlight frames, a vertical lever pivotally carried on said linkage frame about a pivot axis, an upwardly bent connecting rod interconnecting said opposite end of one of said angled arms and an upper portion of said vertical lever at a certain distance from the pivot axis, a downwardly bent connecting rod connecting said opposite end of the other angled arm and a lower portion of said vertical lever at a distance equal to said certain distance from the pivot axis, and a drive transferring cable having one end length-adjustably connected with said vertical lever and the other end connected with said manually moveable lever.
