Abstract
Abstract To permit the use of light-weight material in the construction of a bicycle carrier, without connecting rivets, an article carrying surface is formed of a grid structure having longitudinal bars and cross rods, in which the bars and cross rods are connected together by means of a molded plastic connecting element forming a single injection molding, molded in place around the bars and the terminal ends of the cross rods, the bars and cross rods preferably being deformed from a smooth shape (circular, square, or the like) to improve holding action of the injection molding. The injection molding may be serrated, or knurled at the top surface, and formed integrally with protective plastic coverings for the bars and cross rods respectively.

Claim 1
Independent Claim
96 words
Cycle luggage carrier construction having a grid structure defining an article carrying surface, said grid structure being formed by rod-like grid elements comprising longitudinal bar elements (3) and cross rod elements (4), characterized by molded plastic connecting elements (5) connecting and joining together the cross rod elements and respective longitudinal bar elements (3), forming a single injection molding molded, in place, around said bar elements (3) and the terminal ends of the cross rod elements (4); and wherein the molded plastic connecting elements (5) are formed with article carrying surfaces on at least one side thereof.
Claim 2
Dependent Claim
96 words
Cycle luggage carrier construction having a grid structure defining an article carrying surface, said grid structure being formed by rod-like grid elements comprising longitudinal bar elements (3) and cross rod elements (4), characterized by molded plastic connecting elements (5) connecting and joining together the cross rod elements and respective longitudinal bar elements (3), forming a single injection molding molded, in place, around said bar elements (3) and the terminal ends of the cross rod elements (4); and wherein the molded plastic connecting elements (5) are formed with article carrying surfaces on at least one side thereof.
Claim 3
Dependent Claim
27 words
Construction according to claim 1, wherein the plastic connecting element (5) is formed with a serrated, or knurled surface at the side forming the article carrying surface.
Claim 4
Dependent Claim
20 words
Construction according to claim 1, wherein the plastic connecting element (5) is extended longitudinally along the longitudinal bar elements (3).
Claim 5
Dependent Claim
18 words
Construction according to claim 1, wherein the connecting element (5) is extended longitudinally along the cross rods (4).
Claim 6
Dependent Claim
33 words
Construction according to claim 1, wherein adjacent plastic connecting elements on said grid structure are extended along the respective rod element and joined together to form a plastic covering for the respective element.
Claim 7
Dependent Claim
30 words
Construction according to claim 1, wherein at least one of said plastic connecting elements (5) is formed with a connecting eye (12) to permit connection of a holding strap thereto.
Claim 8
Dependent Claim
42 words
Construction according to claim 1, wherein at least one of said grid elements (3, 4) is formed with a deformation (13, 14, 15, 16) in the region beneath a molded plastic connecting element (5), said connecting element being molded around said deformation.
Claim 9
Dependent Claim
19 words
Construction accordIng to claim 7, wherein the deformation comprises a zone of enlarged transverse dimension of the rod element.
Claim 10
Dependent Claim
75 words
Construction according to claim 1, further comprising attachment struts (8, 9) for said carrier hinged to said bars (3) and adapted for connection essentially centrally of the wheel of a cycle, characterized in that the attachment struts comprise two spaced support portions (9) and an integral connecting portion (8), and molded plastic hinge connections (10) are provided, molded around the terminal ends of the bars (3) and the integral connecting portion (8) of the struts.
