Abstract

A bicycle axle assembly where the axle body serves as storage for a removable quick release lever. The quick release lever will preferably comprise of two ends, the first comprising a bayonet coupling for attaching said lever for operation, and a second end for storage, comprising an elastic element. The storage facility with the wheel axle will preferably comprise of a main axle body with two ends, a first end which is threaded on its exterior and a second end shaped as a collar and threaded on its interior. The detachable handle/lever will preferably be held in place in the axle by engaging with an internal bayonet fitment.

Description

Quick Release Cycle Axle Bicycle technology has advanced a pace in the last few years, particularly in the area of wheels and their mounting on and releasing from the bicycle forks or frame.
The prior art figure shows a state of the art axle with quick mounting and releasing mechanism. Essentially this consists of the axle with a screw thread at one end to screw a securing nut onto and at the other end a quick release cam lever to hold the wheel in the fork.
To fasten the wheel, the axle is pushed into the fork and the nut tightened finger tight. When the nut is judged tight enough then the quick release cam lever is flicked over to increase the pressure and move the lever into a position flat against the cycle frame.
However, with the forks being the widest part of the bike, the lever often protrudes by an undesirable distance from the fork leg or frame and is often susceptible of being caught or damaged by immovable objects.
This is particularly prevalent on mountain bikes which have to endure a fair amount of hard wear and tear.
The inventor sat down to create a quick mounting wheel axle without those problems. He hit upon the idea to make the quick release lever removable after the wheel is fixed into the fork.
To avoid the age old problem of the clamping lever getting mislaid or lost, a means was needed to be found for keeping the lever with the bike but out of the way of knocks and bumps. The best way to store the lever on the bike was found to be inside the corresponding wheel axle.
Thus, the clamping lever has a bayonet type fitting on one end and handle on the other. For mounting the wheel the lever is introduced into the axle and fixed by means of the bayonet fitting with the lever end sticking out from the bike frame.
The inventive axle has an external thread on one end which screws into one fork leg. The opposite end of the axle shows a widened collar formed onto it, which has an internal thread to receive the bayonet type fitting end nut. The end nut holds a spring inside the collar which acts as the flexible resistance to the bayonet type end of the quick release lever.
To assemble the wheel in the frame, the quick release lever is pushed into the collared end of the axle and turned through 90 degrees to locate it.
The axle is then guided through the left hand fork leg and the quick release lever is turned to screw the assembly into the right hand fork leg to tighten the wheel in the forks. Naturally, the assembly could also be designed to be left handed rather than right handed.
When all slack is taken up and the wheel is securely held in the forks, the quick release lever is removed from the axle, reversed and reintroduced into the axle for safe keeping by pushing it into the bayonet profile of the axle and turning through 90 degrees. An 0-ring seal prevents any rattling between the lever and the inside surface of the axle.
Detailed description of the invention.
The invention will now be described with reference to the drawings.
Figs 1 to 4 show perspectives views of the invention from storage (fig1) to assembled for use (fig 4).
Fig 5 shows a perspective view of the axle on its own and Fig 6 shows the collared end exploded.
Fig 7 shows a perspective view of the quick release lever and Fig 8 shows the same in exploded view.
Fig 9 shows an end view of the axle (1) together with a cross-section of that axle and the lever ready for clamping action Fig 10 shows an end view of the same axle (1) together with a cross-section view of the axle and the lever in its storage position.
The axle, shown in figure 6, comprises a main axle body (1) with an end (6) on which an external thread is formed. The other end comprises a widened section or collar which is threaded on its inside.
A spacer ring (3) and a spring (2) are held inside the collar by an end nut (4) which starts life as an end cap. This end nut (4) screws into the collar and together with the spring trapped inside forms the socket part of a bayonet type fitting.
It has an opening (5) which is formed from a round hole overlaid with a slot, the ends of which slot extend beyond the diameter of the round hole, thus forming a "flared" hole, the flared part extending beyond the internal diameter of the main axle body (1).
On the inside of the "flared" hole a larger round hole of the same diameter as the outer ends of the flared part forms an undercut in the end nut (4). Said spacer (3) has an internal diameter identical to the internal diameter of the axle barrel (1) and serves to hold the spring (2) in place.
The second 'male' part of the bayonet type fitting is provided by the quick release lever. This lever assembly comprises 4 parts as shown in Fig 8. Those are a main handle part (7), a 'male' bayonet type engaging part (10), a pivot pin (8) and an 0-ring (11).
The engaging part (10) is shaped as a complimentary shape to the hole in the end nut (4) to enable part (10) to interact with nut (4). Said engaging part (10) shows a protrusion (9) on its end which has flattened sides parallel to the flares in hole (5).
Assembled for use the part (10) engages the opening in nut (4) and turned through 90 degrees. The spring (2) ensures a positive mechanical engagement with the nut (4). The handle part (7) is then bent through 90 degrees by means of the pivot pin (8).
The screw thread on the axle end (6) screws into an internal screw thread within the right hand leg of the fork.
The quick release lever is then used to turn the axle into the thread at its opposite end (6). When tightened down, the quick release lever is removed (by a 90 degrees turn), reversed and simply pushed into the axle (1) and turning through 90 degrees for storage as indicated in figures 1, 2 and 10.
The then leading end of the quick release lever shows an 0-ring (11) which prevents any rattling noise between the lever and the inside surface of the axle (1) during normal usage of the bicycle.

Claims (10)

  1. CLAIMS1. A bicycle axle assembly comprising a detachable quick release lever which is stored before and after use in a safe place on the bicycle.
  2. 2. A bicycle axle assembly according to claim 1 wherein said safe place is inside said axle.
