Patent EA-003504-B1 (EA)
Title: Elongate member with interconnected rotatable portions
IPC: F21V21/36
Filed: 2000-10-04
Abstract: 1. An elongate member for locating an article remote from a base position, characterized in that the elongate member comprises an inner elongate portion, the inner elongate portion extending, in use, from the base position, an outer elongate portion, the outer elongate portion being arranged to receive the article, and interconnecting means, the interconnecting means being arranged to connect the inner elongate portion to the outer elongate portion and to permit relative rotation of the inner and outer portions about an axis of rotation, the axis of rotation being disposed at an acute angle relative to a longitudinal axis of the inner elongate portion. 2. An elongate member according to Claim 1, characterized in that the outer elongate portion is arranged to move between a first position whereby the outer elongate portion is substantially parallel to the inner elongate portion and a second portion whereby the outer elongate portion is substantially perpendicular to the inner elongate portion. 3 An elongate member according to Claim 1 or Claim 2, characterized in that the acute angle is between 30 degree and 60 degree . 4. An elongate member according to any one of the preceding claims, characterized in that the interconnecting means includes a first plate member fixedly attached to the inner elongate member at an end remote from the base position, and a second plate member fixedly attached to the outer elongate member of an end remote from the article wherein, in use, the first plate member is located adjacent the second plate member. 5. An elongate member according to Claim 4, characterized in that the first plate member has an upper surface and the second plate member has a lower surface, the upper surface of the first plate member being adjacent the lower surface of the second plate member in use, and the axis of rotation being perpendicular to the upper surface of the first plate member. 6. An elongate member according to Claim 4 or Claim 5, characterized in that the interconnecting means includes a fixing means, the fixing means being arranged to releasably engage the first plate member and the second plate member such that, in use, when the first and second plate members are engaged by the fixing means relative rotation of the first and second elongate members is restricted. 7. An elongate member according to Claim 6, characterized in that the fixing means includes a third plate member, the third plate member including a centrally disposed aperture and being arranged to locate, in use, about the outer elongate portion and adjacent the second plate member, wherein adjustable connection means is arranged to connect the first plate member and the third plate member such that tightening of the adjustable connection means engages the fixing means. 8. An elongate member according to any one of Claims 4 to 7, characterized in that the first plate member has at least one aperture, and the second plate member has at least one aperture, and wherein the aperture of the first plate member is adjacent to the aperture of the second plate member when the first elongate portion and the second elongate portion are arranged in a particular position, and wherein the interconnecting means includes a pin member arranged, in use, to locate within the aperture of the first plate and the aperture of the second plate and thus restrict relative rotation of the inner elongate member and the outer elongate member. 9. An elongate member according to Claim 8, characterized in that the second plate member has a first aperture and a second aperture and wherein rotation of the outer elongate member relative to the inner elongate member causes an aperture of the first plate member initially adjacent the first aperture of the second plate member to be subsequently adjacent the second aperture of the second plate member. 10. An elongate member according to any one of the preceding Claims, characterized in that the interconnecting means includes a cylindrical portion arranged to be coaxial with the axis of rotation, and wherein the cylindrical portion extends from one of the inner and outer elongate portions and wherein the other of the inner and outer portions includes an aperture arranged to receive the cylindrical portion. 11. An elongate member according to any one of the preceding Claims, characterized in that the article includes a light source. 12. An elongate member according to any one of the preceding claims characterized in that the inner elongate portion is arranged to be mounted to a surface at the base position.
