Abstract
Abstract A headlamp assembly includes a rectangular lamp unit having a pair of flanges which project from opposite sides of the unit respectively. The flanges lie on an imaginary line parallel with the horizontal axis of the lamp unit, and has engaged therewith respective screws. The screws are engaged at one end with the flanges for angular movement relative to the flanges, and are engaged at their opposite ends with respective nuts which are affixed to a support member. The arrangement is such that rotation of one of the screws in a direction to move its respective flange towards the support member while rotating the other screw through the same angular distance but in a direction to move its respective flange away from the support member, so as to adjust the attitude of the lamp unit with respect to the support member about a vertical axis passing through the midpoint of said imaginary line.

Claim 1
Independent Claim
205 words
A headlamp assembly including a rectangular lamp unit having a pair of flanges which project from opposite sides of the unit respectively and which lie on an imaginary line parallel with the horizontal axis of the lamp unit, a support member, a pair of screws engaged at one end with said flanges respectively for angular movement thereto, the screws being axially fixed relative to the flanges, and being engaged with respective nuts fixed to said support member, and a pair of guides carried by the support member extending outwardly therefrom and coacting with said pair of flanges on opposite sides of the lamp unit, rotation of one of the screws in a direction to move its respective flange towards the support member while rotating the other screw through the same angular distance but in a direction to move its respective flange away from the support member serving to adjust the attitude of the lamp unit with respect to the support member about a vertical axis passing through the midpoint of said imaginary line, and said guide means serving to guide said flanges for movement at right angles to said support member during said adjustment of the attitude of the lamp unit about said vertical axis.
Claim 2
Dependent Claim
205 words
A headlamp assembly including a rectangular lamp unit having a pair of flanges which project from opposite sides of the unit respectively and which lie on an imaginary line parallel with the horizontal axis of the lamp unit, a support member, a pair of screws engaged at one end with said flanges respectively for angular movement thereto, the screws being axially fixed relative to the flanges, and being engaged with respective nuts fixed to said support member, and a pair of guides carried by the support member extending outwardly therefrom and coacting with said pair of flanges on opposite sides of the lamp unit, rotation of one of the screws in a direction to move its respective flange towards the support member while rotating the other screw through the same angular distance but in a direction to move its respective flange away from the support member serving to adjust the attitude of the lamp unit with respect to the support member about a vertical axis passing through the midpoint of said imaginary line, and said guide means serving to guide said flanges for movement at right angles to said support member during said adjustment of the attitude of the lamp unit about said vertical axis.
Claim 3
Dependent Claim
78 words
An assembly as claimed in claim 1 further including a third flange which projects from the upper edge of the lamp unit and a third screw axially fixed relative to the third flange and being engaged with a respective nut fixed to the support member the arrangement being such that rotation of said third screw relative to said third flange serves to adjust the attitude of the lamp unit relative to the support member about said imaginary line.
Claim 4
Dependent Claim
28 words
An assembly as claimed in claim 1 including resilient means acting between the lamp unit and the support member to urge the lamp unit towards the support member.
Claim 5
Dependent Claim
17 words
An assembly as claimed in claim 1 wherein said guide members are moulded in synthetic resin material.
Claim 6
Dependent Claim
23 words
An assembly as claimed in claim 1 wherein each of said guide members is engaged as a snap fit with the support member.
