Abstract
Abstract A headlight mounting and adjustment mechanism particularly suited for use in a motor vehicle for adjusting the direction in which the headlight is aimed includes a headlight assembly elastically yieldably supported by a headlight support at one location. A dual adjustment device is provided for effecting the up-and-down or vertical adjustment and also the left-to-right or horizontal adjustment of the headlight assembly. The dual adjustment device includes a sliding block supported for sliding movement between front and rear positions by a guide wall structure fixedly attached to the headlight support, and the sliding block has a bearing projection operatively and rotatably coupled to the headlight assembly, a horizontal adjusting bolt member threadingly extended through the slide block and received by the headlight support, and a vertical adjusting bolt member having one end coupled to the headlight assembly and the other end threadingly engaged with the sliding block or the headlight support so that by turning the vertical adjusting bolt member the up-and-down adjustment of the headlight assembly is achieved.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
250 words
A headlight mounting and adjustment mechanism comprising: a headlight assembly for housing an electric light which when energized emits a beam of light in a direction; a headlight support fixedly positioned with respect to said headlight assembly; a first connecting means operatively associated with a first portion of said headlight assembly and said headlight support for pivotally connecting said headlight assembly to said headlight support; a sliding block supported for movement toward and away from said headlight support and between first and second positions; a guide means fixedly connected to said headlight support for slidably supporting said sliding block during movement between said first and second positions; a second connecting means operatively associated with a second portion of said headlight assembly and said sliding block for rotatably mounting said headlight assembly on said sliding block and for rotatably supporting said headlight assembly relative to said sliding block about an axis extending between the pivotal connection of said headlight assembly to said headlight support and the rotatable mount of said headlight assembly to said sliding block; a first adjusting member operatively associated with said sliding block and said headlight support for sliding said sliding block for pivoting said headlight assembly about the pivotal connection of said headlight assembly to said headlight support; and a second adjusting member operatively associated with a third portion of said headlight assembly and said sliding block for varying the distance between said third portion and said sliding block for rotating said headlight assembly about said axis.
Claim 2
Dependent Claim
250 words
A headlight mounting and adjustment mechanism comprising: a headlight assembly for housing an electric light which when energized emits a beam of light in a direction; a headlight support fixedly positioned with respect to said headlight assembly; a first connecting means operatively associated with a first portion of said headlight assembly and said headlight support for pivotally connecting said headlight assembly to said headlight support; a sliding block supported for movement toward and away from said headlight support and between first and second positions; a guide means fixedly connected to said headlight support for slidably supporting said sliding block during movement between said first and second positions; a second connecting means operatively associated with a second portion of said headlight assembly and said sliding block for rotatably mounting said headlight assembly on said sliding block and for rotatably supporting said headlight assembly relative to said sliding block about an axis extending between the pivotal connection of said headlight assembly to said headlight support and the rotatable mount of said headlight assembly to said sliding block; a first adjusting member operatively associated with said sliding block and said headlight support for sliding said sliding block for pivoting said headlight assembly about the pivotal connection of said headlight assembly to said headlight support; and a second adjusting member operatively associated with a third portion of said headlight assembly and said sliding block for varying the distance between said third portion and said sliding block for rotating said headlight assembly about said axis.
Claim 3
Dependent Claim
69 words
A headlight mounting and adjustment mechanism as claimed in claim 1, wherein: said first adjusting member is threadably engaged with said sliding block; said first portion is located along a first peripheral edge of said headlight assembly; said second portion and said third portion are located along a second peripheral edge of said headlight assembly; and the first and second peripheral edges are opposite edges of said headlight assembly.
Claim 4
Dependent Claim
63 words
A headlight mounting and adjustment mechanism as claimed in claim 1, wherein said first connecting means comprises: a first mounting stay attached to said first portion; a resilient bearing block made of elastic material and rigidly mounted on said headlight support; and a connecting member threadably engaged with said resilient bearing block and rotatably and axially non-movably connected to said first mounting stay.
Claim 5
Dependent Claim
162 words
A headlight mounting and adjustment mechanism as claimed in claim 1, wherein: said second connecting means comprises a second mounting stay attached to said second portion and said third portion, a first tongue connected to said second mounting stay and rotatably mounted on said sliding block and extending in one direction substantially parallel to the direction of a beam of light from said headlight assembly, and a second tongue connected to said second mounting stay and extending in a direction substantially perpendicular to said one direction; and said second adjusting member is rotatably and substantially axially non-movably connected to said second tongue for, when rotated in a first direction, moving said second tongue and said third portion toward said sliding block and rotating said headlight assembly relative to said sliding block and for, when rotated in a second direction, moving said second tongue and said third portion away from said sliding block and rotating said headlight assembly relative to said sliding block.
Claim 6
Dependent Claim
46 words
A headlight mounting and adjustment mechanism as claimed in claim 4, wherein: said sliding block has a bearing projection axially extending in a direction substantially perpendicular to the longitudinal axis of said first adjusting member; and said first tongue is rotatably mounted on said bearing projection.
Claim 7
Dependent Claim
38 words
A headlight mounting and adjustment mechanism as claimed in claim 1, 2, 3 or 4, wherein: said guide means is an open-ended member having a box-like shape; and said sliding block is movably housed within said guide means.
Claim 8
Dependent Claim
180 words
A headlight mounting and adjustment mechanism as claimed in claim 3, wherein: said second connecting means comprises a second mounting stay attached to said second portion and said third portion, a first tongue connected to said second mounting stay and rotatably mounted on said sliding block and extending in one direction parallel to the direction of a beam of light from said headlight assembly, and a second tongue connected to said second mounting stay and extending in a direction substantially perpendicular to said one direction; said resilient bearing block biases said third portion and said second tongue away from said sliding block; and said second adjusting member is rotatably connected to said second tongue for, when rotated in a first direction, moving said second tongue and said third portion toward said sliding block and rotating said headlight assembly relative to said sliding block and for, when rotated in a second direction, resulting in movement of said second tongue and said third portion away from said sliding block and resulting in rotation of said headlight assembly relative to said sliding block.
