Abstract
Abstract A vehicular headlight position adjusting assembly (100) is provided. Assembly (100) includes a two-part housing (2, 4) within which meshingly engaged gears (22, 32) are rotationally supported in a manner providing an angular relationship between their respective rotational axis. Gears (22, 32) are rotated by an input drive member (16) extending from housing (2, 4). Gear (32) is threadingly engaged with an adjustment member (20) having an end operatively engaged with a movable frame (46) upon which the headlight is mounted and having an elongate flat (26) that slidingly engages a projection (24) of gear (22) operative to prevent adjustment member (20) from rotating such that rotation of drive member (16) in opposite directions causes adjustment member (20) to traverse without rotation in opposite directions to adjust the headlight position.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
226 words
A vehicular headlight position adjusting assembly comprising: intermeshed drive and driven gears having their respective rotational axis angularly displaced from each other, an elongate drive member drivingly connected to the drive gear and operable upon rotation to cause both the drive gear and the driven gear to rotate about their respective rotational axis an elongate adjusting member threadingly engaged with the driven gear and having an end thereof adapted to engage a movable frame upon which the headlight is mounted, a housing comprising first and second housing members releasably joined together and adapted to protectively enclose the drive and driven gears and having respective openings therein enabling the drive and adjusting members to extend therefrom, means for securing the housing to a fixed frame on the vehicle so as to enable the adjusting member to move the movable frame in response to rotation of the drive member, and means within the housing members for preventing the adjusting member from rotating whilst enabling the adjusting member to traverse in opposite axial directions in response to rotation of the drive member in opposite rotational directions, said means comprising an elongate flat on the adjusting member that is slidingly engaged with a projection from the drive gear operable to prevent the adjusting member from rotating whilst enabling the adjusting member flat to slide in opposite axial directions relative thereto.
Claim 2
Dependent Claim
226 words
A vehicular headlight position adjusting assembly comprising: intermeshed drive and driven gears having their respective rotational axis angularly displaced from each other, an elongate drive member drivingly connected to the drive gear and operable upon rotation to cause both the drive gear and the driven gear to rotate about their respective rotational axis an elongate adjusting member threadingly engaged with the driven gear and having an end thereof adapted to engage a movable frame upon which the headlight is mounted, a housing comprising first and second housing members releasably joined together and adapted to protectively enclose the drive and driven gears and having respective openings therein enabling the drive and adjusting members to extend therefrom, means for securing the housing to a fixed frame on the vehicle so as to enable the adjusting member to move the movable frame in response to rotation of the drive member, and means within the housing members for preventing the adjusting member from rotating whilst enabling the adjusting member to traverse in opposite axial directions in response to rotation of the drive member in opposite rotational directions, said means comprising an elongate flat on the adjusting member that is slidingly engaged with a projection from the drive gear operable to prevent the adjusting member from rotating whilst enabling the adjusting member flat to slide in opposite axial directions relative thereto.
Claim 3
Dependent Claim
158 words
The assembly of claim 1 wherein the means for securing the housing to a fixed frame comprises: a projection extending from the housing adapted to extend through an opening in the fixed frame when the housing is abutted thereagainst, a transverse groove in the projection positioned to lay adjacent the opposite side of the frame opening through which the housing projection is inserted, at least one axial extending groove in the projection that is exposed on the opposite side of the frame opening into which the projection is received and is oriented substantially orthogonal to the transverse groove, and a clip having an open-ended slot therein having an edge adapted to engage the projection transverse groove and prevent the projection from moving axially within the frame opening and having at least one resilient arm extending from the clip to a free-end thereof adapted to engage the orthogonal groove and thereby prevent the projection from rotating relative the frame.
Claim 4
Dependent Claim
44 words
The assembly of claim 1 wherein the housing members are releasably joined together by means of a hinged engagement therebetween operable to enable one of the housing members to pivot away from the other housing member for a distance sufficient to provide access therewithin.
