Abstract

A quick release apparatus for a bicycle tire or tube is provided, which reduces time and effort spent in changing the tire or tube. A main wheel frame and a sub wheel frame are provided. These two frames with rim respectively can be assembled to construct a complete wheel frame set. When said main wheel frame connects with the sub wheel frame, it provides a complete rim with two walls for containing the tube. When said main wheel frame leaves said sub wheel frame, it generates a gap between these two frames for removing the tube easily.

First claim

What is claimed is:

1. A rim quick release apparatus for bicycle tire or tube changing, comprising:
a wheel frame set which comprises:
a main wheel frame comprising a main rim;
said main rim comprising a rim well having two edges, a first rim flange vertically connecting with one edge of the rim well, another edge of the rim well having a first connecting surface;
said main wheel frame further comprising a hub pipe, a flange is circumferentially set on a surface of the hub pipe along a direction perpendicular to the axis thereof, the surface of the hub pipe is thereby divided into two sections by said flange, said flange attached with multiple spokes which extend for connecting to the rim well;
a sub wheel frame comprising a sub rim, said sub rim connects to the main rim by assembling said sub wheel frame with the main wheel frame;
said sub rim comprises a second rim flange having a second connecting surface;
said sub wheel frame further comprising a ring having multiple spokes extending to connect with said second rim flange.

2. The rim quick release apparatus for bicycle tire or tube changing of claim 1 , wherein the wheel frame set further having two assembling forms, said wheel frame set is assembled by inserting a section of said hub pipe into said ring of the sub wheel frame, a position of the ring is arranged on the section of said hub pipe;
under an attached form of the wheel frame set, said flange of the main wheel frame attaches to the ring of the sub wheel frame, said first connecting surface is thereby connected to said second connecting surface, combining the main rim and the sub rim to form a container; and
under a released form of the wheel frame set, said flange no longer attaches to said ring and said first connecting surface no longer attaches to the second connecting surface, separating the wheel frame set to generate a gap between said first connecting surface and said second connecting surface, wherein multiple matching slots constrain said spokes of the sub wheel frame in a pre-set range.

3. The rim quick release apparatus for bicycle tire or tube changing of claim 2 , further comprising:
an inner spring set between the flange of the main wheel frame and the ring of the sub wheel frame;
a sleeve tube having a cap, said sleeve tube mounts on said section of the hub pipe and connects to said ring of the sub wheel frame, an opening is provided on the cap as an access to an inside hollow of said hub pipe;
a quick release hub axle which has two ends, a first end is inserted into said hub pipe from the section opposite to the one being inserted into said ring of the sub wheel frame, and penetrates through the hub pipe and the sleeve tube, a bar cap is set on said first end of the quick release hub axle and a blocking ring is set on said first end, an outer spring sets between the bar cap and the blocking ring, a quick release lever is set on a second end of said quick release hub axle;
a bicycle fork set which contains two forks, one fork connects to the quick release hub axle on the section between said quick release lever and said hub pipe, another fork connects to the quick release hub axle on the section between said blocking ring and said outer spring;
locking of the quick release lever compresses both the outer spring and the inner spring, said wheel frame set is thereby under the attached form; and
releasing of the quick release lever releases both of the inner spring and the outer spring, said wheel frame set changes to released form.
