Description
. .
This invention relates to a kit of components for mechanically assembling a bicycle support rack, and structures therefor.
BACKGROUND OF INVENTION
Racks -For supporting bicycles (bicycle racks) constructed of metal and used throughout the world are commonly of an upstanding shape comprising two vertical parallel spaced apart support members to receive an upstanding bicycle wheel intermediate the two vertical support members and a base therefor. Usually, the support members comprise loops which form a plane of suppor-t corresponding to the plane of a bicycle wheel.
The vertical, parallel spaced apart loops are supported usually by horizontally extending members suf-Ficiently arranged to form a stable base. Usually the vertical loops and base are comprised of components which are welded together.
In other embodiments, two parallel spaced apart support members are oriented on any axis sufficient to receive and support -therebetween a suitable member of a bicycle frame.
While existing bicycle racks have been suitable for commercial or public applications, the fact tha-t they are welded together or com prised of relatively heavy components has not permitted them to be suitable for pr-ivate residential purposes. No one has provided a kit for mechanically asse~bling a lightweight yet sturdy bicycle rack suitable for private residential purposes, constructed of a minimum number of components which are inexpensively produced and easily assembled.
Further and other objects of the invention will be realized by those skilled in the art from the -following summary of the invention and detailed description of embodiments thereof.

Swaged ends 30 of 29 inch bicycle rack section 49 may fric-tionally telescope into receptive ends 32 of 40~2 inches bicycle rack section 51 to provide a bicycle rack sufficient to receive and support 5 bicycles. Where bicycle rack sections 49, 51 are not connected, end caps 53 are provided to fit over ends of tubes 13, 15, 17.
With reference to Figure 2, in one preferred embodiment of the invention, there is shown an end view of the bicycle rack 11 in Figure 1, whereby the horizontal tubes 13, 15, 17 support the circumference of a bicycle wheel 55 at three points.
With reference to Figure 8, there is shown an end view of a 7~22 1 bicycle rack 11 supported from a wall 57 by a lateral bracket 59, and bolt 61.
