Claim 1
Independent Claim
208 words
A lamp assembly comprising a lamp unit, a support member, and means securing the lamp unit to the support member, said means affording adjustment of the orientation of the lamp unit relative to the support member and including a first screw-threaded part carried by the support member, a second screw-threaded part in screw-threaded engagement with the first part and rotatable relative thereto, a flange secured to the lamp unit and having therein a slot open at one edge of the flange, the flange extending generally perpendicularly to the axis of said second screw-threaded part, a coupling member extending through said slot and having respective surfaces engaging opposite faces of the flange so as to prevent movement of the coupling member relative to the flange in a direction perpendicular to the flange, means resisting movement of the coupling member along the length of the slot in the flange, a part-spherical recess in a portion of the coupling member presented to the support member, and a part-spherical end portion on the second screw-threaded part, the part-spherical end portion being received as a snap-fit in the recess of the coupling member and the part-spherical end portion and the recess defining a ball-and-socket connection between the support member and the lamp unit.
Claim 2
Dependent Claim
208 words
A lamp assembly comprising a lamp unit, a support member, and means securing the lamp unit to the support member, said means affording adjustment of the orientation of the lamp unit relative to the support member and including a first screw-threaded part carried by the support member, a second screw-threaded part in screw-threaded engagement with the first part and rotatable relative thereto, a flange secured to the lamp unit and having therein a slot open at one edge of the flange, the flange extending generally perpendicularly to the axis of said second screw-threaded part, a coupling member extending through said slot and having respective surfaces engaging opposite faces of the flange so as to prevent movement of the coupling member relative to the flange in a direction perpendicular to the flange, means resisting movement of the coupling member along the length of the slot in the flange, a part-spherical recess in a portion of the coupling member presented to the support member, and a part-spherical end portion on the second screw-threaded part, the part-spherical end portion being received as a snap-fit in the recess of the coupling member and the part-spherical end portion and the recess defining a ball-and-socket connection between the support member and the lamp unit.
Claim 3
Dependent Claim
100 words
A lamp assembly as claimed in claim 1, wherein a pair of opposite edges of the flange are bent to extend at right angles to the plane of the flange, so as to define a channel presented away from the support member, the surface of the coupling member which engages the face of the flange remote from the support member being a surface of a head of the coupling member which is received in said channel, the head of the coupling member and the wall of the channel serving to resist rotation of the coupling member relative to the flange.
Claim 4
Dependent Claim
108 words
A lamp assembly as claimed in claim 1, wherein said means resisting movement of the coupling member along the length of the slot includes a projecting portion on the wall of the slot between the open and closed ends of the slot whereby the width of the slot intermediate its closed end and its open end is reduced, the coupling member having a portion between said surfaces which is engaged as a snap-fit in the region of the slot adjacent the closed end of the slot by urging the coupling member along the length of the slot, in use, beyond said region of the slot of reduced width.
Claim 5
Dependent Claim
41 words
A lamp assembly as claimed in claim 1, wherein the flange is positioned so that the region of the flange containing the slot lies nearer to the support member than the point of interconnection between the flange and the lamp unit.
Claim 6
Dependent Claim
88 words
A lamp assembly as claimed in claim 1, wherein a pair of the said securing means are provided for adjustably securing the lamp unit to the support member, and a pivot assembly also pivotally secures the lamp unit to the support member, the arrangement of the pair of securing means and the pivot asseMbly being such that adjustment of either of the securing means causes movement of the lamp unit relative to the support member about an axis passing through the other securing means and the pivot assembly.
Claim 7
Dependent Claim
16 words
A lamp assembly as claimed in claim 5, wherein the pivot assembly includes a ball-and-socket connection.
