## Background
FIELD OF THE INVENTION
This instant invention relates generally to retractable security cable instrumentalities and, in particular, to a retractable security cable device particularly for use with bicycles.
BACKGROUND OF THE INVENTION
Due to changes in economics, air quality, long-term pollution effects on the environment and the public's awareness of a need to conserve energy and protect the environment, the number of individuals that use bicycles as their principal mode of transportation has increased in recent years. Because of the nature of the weight and size of bicycles, this vehicle is prone to theft. For example, even if a bicycle is secured such that the wheel will not rotate, it is generally light weight enough that it can be carried away, rendering the removal of the security device at a remote site relatively easy to the thief. Thus, the need for an efficient, effective means to secure a bicycle while it is not in use has led to the development of many different types of bicycle security systems or devices.
For example, the patent to Kloke (U.S. Pat. No. 5,065,603, issued Nov. 19, 1991) teaches a tubular lock and method for mounting same. Kloke teaches a cable captured within a tubular housing externally adhered, via double sided tape, to the exterior of the frame of the bicycle, wherein the cable is manually pulled out and pushed back into the housing. The adhered tubular housing can be easily removed from the bicycle.
The patent to Hoffman (U.S. Pat. No. 6,505,846 issued Jan. 14, 2003) teaches a bicycle cable locking system. A double length cable is stowed in a frame tube of a bicycle and automatically surrounds the head of the bicycle frame. The spring, however, which provides the cable with its retraction means is not replaceable. That is, once the spring or cable snaps or breaks, there is no way to repair or replace them, thereby rendering the locking system inoperable. Hoffman further teaches retrofits which share the problem of having no way to repair or replace a broken spring and further suffers from the problem of being easily removed from the bicycle.
For the foregoing reasons, there is a need for a device which provides an effective and efficient means by which to secure a bicycle while it is not in use such that the bicycle is not merely carried away (even if its rotation means, i.e., wheels, are hindered).
In addition, a need exists for a security device for bicycles wherein the cables or parts which comprise the bicycle locking system or device cannot merely be mutilated on site, such that the security device is easily removed and the bicycle stolen.
Moreover, a need exists for a locking system or security device for a bicycle which is not rendered permanently inoperable upon component breakage and/or failure.
None of the known prior art overcomes the above deficiencies.
BRIEF SUMMARY OF THE INVENTION
This invention is distinguished over the known prior art in a multiplicity of ways. For one thing, an embodiment of the invention provides a repairable retractable security cable device or system which solves the problem of becoming rendered permanently inoperable upon component breakage and/or failure.

Additionally, openings 40, 140 are sized to allow the second cable stop 68 and the second cable end 64 of the cable 60 to freely pass therethrough and are preferably formed integrally in first frame members 32, 132 proximate rear portions 34, 134 and distal to openings 42, 142 respectively. Likewise, openings 42, 142 are preferably formed integrally in the first frame members 32, 132 proximate front portions 36, 136 and distal to openings 40, 140 respectively. Openings 42, 142 are preferably reinforced around their edges to form a beveled-edge protective wall about the periphery of the openings or bores to provide a good frictional surface upon which the cable 60 slides easily, without damaging the paint or scratching the metal of the bicycle frame 11. Preferably, the opening is concave at a location where the cable 60 rides or rubes thereon.
Referring to FIG. 3, one embodiment of the invention provides a lock and cable mounting device 80 attached to the bicycle and in one embodiment, attached to, for example, the handlebar 50 of the bicycle 15 as shown in FIG. 3. The lock and cable mounting device 80 is, in one embodiment, comprised of a tongue coupling member 82 and a groove coupling member 182.
Referring to FIG. 4, the tongue coupling member 82 of the lock and cable mounting device 80 is comprised of a T-shaped tongue member 84 disposed on a top 102 of a clamping means 104. The T-shaped tongue member 84 upwardly extends from a preferably substantially planar top 102 of the clamping means 104 and is comprised of base branch 86 substantially perpendicularly extending from the top of the clamping means at a median location and a top branch 88 substantially perpendicularly extending from base branch 86 and substantially parallel to the top 102 of the clamping means 104 such that a pair of channels 90 and 92 are defined on either side of the base branch 86 and have walls defined by the top 102 of the clamping means, the sides 94, 96 of the base branch 86 and bottoms 98, 100 of the top branch 88.
Referring to FIG. 5, the clamping means 104 includes a generally rectangular body which downwardly depends from and is preferably integrally formed with the T-shaped tongue member 84 and includes top 108, a rounded front end 106, a back end 108, an opening 110 for the handlebar 50 to pass therethrough, a slot 112 passing through the back end 108 of the clamping means and through a sidewall of the opening 110 such that the slot 112 is defined by two side walls 114, 116 which may be compressed toward one another to lessen the size of the opening 110. Thus, the tongue coupling member 82 can be clamped onto handlebar 50 via a threaded fastener 118 passing through a threaded bore 120 disposed in the sidewalls 114, 116 for drawing the sides together for clamping the clamping means 104 and thus the T-shaped tongue member 84 to the handlebar 50 of the bicycle.

In a further aspect of the invention, a device or instrumentality is provided as characterized above which prevents pinching and lash back of the cables where the cable enters an outlet in a bicycle frame while the device is in a stowed position, but while the bicycle is being ridden.
In a further aspect of the invention, a device or instrumentality is provided as characterized above which provides a good frictional surface on the outlets formed in the bicycle frame so that the through passage of the security cable does not damage the frame or the paint.
In a further aspect of the invention, a device or instrumentality is provided as characterized above which provides a cable having a first cable length, extending from a first cable outlet of a frame member and terminating to a first end, wherein the first cable length is greater than the length of a spring that is attached to a second end of the cable and housed within an open ended housing such that the spring can be pulled out of its housing a maximum length equal to the first cable length which allows easy removal of the spring.
These aspects, among other things, demonstrate industrial applicability of this invention.
