1 FIELD OF INVENTION
. .
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.
SUMMARY OF INVENTION
According to one aspect of the invention, a bicycle rack is
provided comprising parallel spaced apart uprights, horizontal tubes

1 communicat;ng between the uprights and connected thereto, the improve-
ment comprising a kit of components for mechanically assembling a
bicycle rack comprising a plurality of substantially U-shaped tubes of
equal length whereby at least two opposite and aligned substantially U-
shaped tubes of equal length connect to form a closed loop providinguprights positioned transversely to at least two parallel spaced apart
horizontal tubes of equal length communicating between and connected to
the uprights, thereby providing a base for the bicycle rack.
According to another aspect of the invention, one end of each
horizontal and each substantially U-shaped tube is of an exterior dia-
meter (male end) substantially equal to the interior diameter of the
opposite end (female end), and carries a plurality of spaced apertures
through the diameter of the tube suitable for receiving a bolt there-
through.
According to another aspect of the invention, the kit for
mechanically assembling the bicycle rack comprises a plurality of
substantially U-shaped tubes of equal length, each having one end swaged
to provide an exterior diameter substantially equal to the interior
diameter of the other end whereby two substantially U-shaped tubes of
equal length one directed towards the other having one swaged end of
each of the substantially U-shaped tubes opposite and aligned with
another receptive end of the opposite substantially U-shaped tube, the
pair of substantially U-shaped tubes telescoping frictionally together
to form a closed loop are provided comprising an upright loop carrying a
plurality of spaced apertures therethrough suitable to receive at least
two carriage bolts communicating with aligned apertures of at least two
parallel spaced apart horizontal tubes of equal length; the at least
two parallel spaced apart horizontal tubes each providing a male end and
an opposite female end thereby being frictionally telescopical with
respect to abutting horizontal tubes, each horizontal tube carrying a
q~2

According to a further preferred embodiment of the invention,
the kit of components For mechanically assembling the bicycle rack
comprising a plurality of substantially U-shaped tubes of equal length
and horizontal tubes of equal length is preferably constructed from
cold rolled low carbon steel of commercial quality comprising substantially
a range of suitable tubular dimensions from one inch diameter of either
16 gauge or 1~ gauge to 3/4 inch diameter of either 16 gauge or 18 gauge.
The substantially U-shaped tubes, each substantially 29~2 inches in
length, at a point substantially equidistant their ends are bent 180
degrees comprising two 90 degree turns, each turn about a radius of
curvature of 3 inches. The substantially U-shaped tube preferably
carries two opposite and aligned apertures, each one spaced 5~2 inches
from the ends of the substantially U-shaped tube and a third aperture
spaced equidistant the ends of the substantially U-shaped tube and
intermediate the substantially semi-circular bend in the tube, preferably
the third aperture permitting a third horizontal tube to communicate
between and connect to upright loops. The horizontal tubes preferably
each substantially 29 inches or 40~2 inches in length depending upon
whether an assembled section of the bicycle rack is to receive and
support 2 or 3 bicycles respectively. Preferably, a plurality of
substantially closely spaced apertures carried by the horizontal tubes
are spaced 2~2 inches apart and a plurality of such pairs of substantially
closely spaced apertures are more broadly spaced 11 inches apart.
Preferably the swaged portion of one end of each substantially U-shaped
tube or each horizontal tube, extends 3 inches from the end thereof,
thereby providing a stable connection and a limit to the extent to which
tubes are telescopical (frictionally) with respect to one another.

closely spaced apart to receive therebetween a bicycle wheel oriented
along its plane, to carry a plurality of such pairs of substantially
closely spaced upright loops substantially broadly spaced to permit the
bicycle rack to support more than one bicycle, and, the plurality of
apertures carried by the substantially U-shaped tubes forming the
upright loops spaced to position the at least two parallel spaced apart
horizontal tubes sufFiciently apart such that the at least two parallel
spaced apart horizontal tubes normally support the circumference of a
standard sized bicycle wheel at two points.
According to another aspect of the invention, preferably the
apertures carried by the horizontal tubes and substantially U-shaped
tubes are punched through the tubes thereby forming an elliptical
depression in the wall of the tube defined by an annular lip comprising
the wall of the tube sufficient that when the apertures of transversely
positioned tubes are aligned a greater tangential surface area is provided
to form a more stable joint spread over a wider area.
According to a preferred embodiment of the invention a third

Wi-th reference to Figure 5, the upright loops 19 are each
comprised of identical substantially U-shaped tubes 27, 27'. U-shaped
tube 27 has one end swaged 29 to provide an exterior diameter 31 sub-
stantially equal to the interior diameter 33 of the receptive end 35 oftube 27. U-shaped tubes 27, 27' are directed one 27 toward the other
27'5 whereby swaged end 29 is aligned with receptive end 35' and recep-
tive end 35 is aligned with swaged end 29'; U-shaped tubes 27, 27'
thereby telescoping frictionally together to form upright loop 19. U-
shaped tube 27 carries two opposite and aligned apertures 21 equallyspaced from the ends 29, 35, thereof to communicate with apertures 39
carried by hori~ontal tube 15. Identical U-shaped tube 27' carries two
opposite and aligned apertures 21' equally spaced from the ends 29', 35'
thereof to communicate with aperture 39 carried by horizontal tube 13
(not shown in Figure 5). It will be appreciated that either top or
bottom apertures 21, 21' may communicate with horizontal tubes 15, 13.
Identical U-shaped tubes 27~ 27' carry apertures 37, 37' spaced inter-
mediate the substantially semi-circular bend 41, 41' in tubes 27, 27'.
