JP4796116B2 - Cut C-shaped tube - Google Patents

Description

  The present invention separates a tube that fills the air in the tire of the wheel into one and the other in the vertical direction from the center of the ring, and closes the separated one and the other into a substantially C-shaped tube. The present invention relates to a substantially C-shaped tube with a cut that can be easily mounted and removed inside a tire without disassembling the wheel axle portion.

Technical background

  Generally, when repairing a puncture of a wheel, take out a part of the annular tube from the inside of the tire of the wheel attached to the axle, put air into the tube, and place the tube into a container with a wide mouth filled with water. I picked them one after another and found a damaged part with a hole and repaired it.

  When exchanging the tube, the wheel axle was disassembled, and after the tube was exchanged, there was an operation to assemble and restore adjustment.

Problems to be solved by the invention

  With a conventional ring-integrated tube, the tube cannot be separated from the wheel axle when repairing punctures. Remove a portion of the tube from inside the wheel tire and place the tube in a water-filled container one after another. There was a problem that it was difficult to pick up, find a damaged part with a hole, and repair it.

  In the conventional annular tube, when the tube is replaced, there is a problem that the axle portion, the brake portion, the chain portion, and the like of the wheel are disassembled, and it takes time and cost to recover after the tube replacement.

  Since the conventional tube integrated with the ring cannot be completely separated from the tire, it is necessary to inspect the inside of the tire for nail or the like that causes damage to the tube in the tire portion, which makes it difficult to inspect.

Means for solving the problem

Therefore, the present invention cuts the annular tube (4) in the vertical direction from the annular center into one and the other, and fits one end to the inner peripheral portion of the cut in the cut (13). A convex lid (5) with a fixed outer peripheral portion is provided and closed, and a valve (6) is provided in the annular central direction on the outer peripheral surface close to the tip of the convex lid (5). The other cut end (14) is provided with a lid (7) leaving the tube in the vicinity of the cut end, and a concave tube (8) is formed between the lid (7) portion and the cut end portion. And a substantially C-shaped tube provided with a hole (9) having a substantially central inner peripheral surface portion of the concave-shaped tube (8) penetrating in an annular central direction. (8) The convex lid (5) is fitted inside, the valve (6) is fitted in the hole (9), and the substantially C-shaped tube is joined in an annular shape. Subjecting the substantially with slit C-shaped tube and said.
Moreover, in the said substantially C-shaped tube joined to the said cyclic | annular form, the joining part joined to the cyclic | annular form of this tube is sometimes omitted, and it is possible to become the substantially C-shaped tube of the original shape.
In addition, the convex lid (5) has a cylindrical outer peripheral portion that fits one end into the inner peripheral portion of the cut end (13) of the annular tube, and has one end portion of the cylinder. It is conceivable to have a configuration that closes.

The invention's effect

    The substantially C-shaped tube with a cut of the present invention does not need to disassemble the wheel axle part, the brake part, the chain part, etc. at the time of puncture repair. Can be separated and separated. Then, the user can freely move to another work place, find a damaged part with a hole, and easily repair. Furthermore, there is no work and cost for reassembling the tube after it is installed.

The best mode for carrying out the present invention will be described below with reference to the drawings. 1 to 7, in the present invention, the annular tube (4) that fills the air in the tire (3) of the wheel (1) is annularly separated from the annular center in one direction and the other in the vertical direction. Make a cut in the tube.
Then, one cut end (13) of the cut is fixed to the inner peripheral portion of the cut, and the outer peripheral portion fitted with one end is fixed, and the convex lid (5) is protruded from the one cut end (13) portion. Provide and close. And the valve | bulb (6) is provided in the outer peripheral surface close | similar to the front-end | tip part of this convex-shaped cover (5) in the center direction of an annular tube.
Furthermore, the other cut end (14) is provided with a lid (7) leaving the tube in the vicinity of the cut end portion, and using the tube left between the cut portions from the lid (7) portion, a concave tube ( 8) Form and close, and form a substantially C-shaped tube provided with a hole (9) penetrating the inner peripheral surface portion of the substantially center of the concave tube (8) in the annular central direction.
Then, the convex lid (5) is fitted into the concave tube (8), and the valve (6) is fitted into the hole (9), so that the substantially C-shaped tube is annular. A substantially C-shaped tube with a cut is provided.

Next, with reference to FIG. 8 and FIG. 9 thru | or FIG. 10, the effect | action and effect of the substantially C-shaped tube with a cut by this Embodiment are demonstrated. First, FIG. 8 shows an occasional form at one end (13) and the other end (14) of the cut portion, which does not disassemble the axle (12) portion of the wheel (1). 9 has an action that can be mounted in a state of a substantially C-shaped tube inside the tire (3). FIG. 9 shows a convex lid ( 5) shows a form in which the valve (6) is fitted in the hole (9) and joined to the annular tube. This can be joined in an annular form from the occasional state shown in FIG. 8 to the one cut (13) and the other cut (14) of the cut portion.
FIG. 10 shows a form in which the substantially C-shaped tube with a cut according to the present invention is mounted inside the tire (3) of the wheel (1). This is because the valve (6) fitted in the hole (9) portion of the joined annular tube is further connected to the rim hole (10) from the outer side of the rim (2) in the tire (3). The rim (2) part is fixed by sandwiching the rim (2) part from the inner peripheral side of the rim (2) outside the tire (3) to the valve (6) part via a valve stop nut (11). This has the effect | action which fixes the joint part of a tube to a rim | limb (2) part.

According to such a substantially C-shaped tube with a cut according to the present invention, the joint portion joined to the annular shape of the tube without disassembling the axle portion of the wheel at the time of puncture repair, sometimes the original shape The substantially C-shaped tube can be easily separated from the tire (3), and there is an effect that the work of disassembling and restoring the axle portion, the brake portion, the chain portion and the like of the wheel becomes unnecessary. Further, the tube can be completely separated from the tire, and there is an effect that it is easy to inspect whether or not a nail or the like causing damage inside the tire is stuck.

  It is AA sectional drawing of FIG. 3 which shows embodiment of the cut substantially C-shaped tube by this invention.   FIG. 3 is a front view in which a substantially C-shaped tube with a cut according to the present invention is mounted inside a tire (3) of a wheel (1).   It is the EE arrow line view of FIG.   It is BB sectional drawing of FIG.   FIG. 5 is an enlarged partial reference view taken along arrow D in FIG. 4.   It is an enlarged partial reference view which shows the form which sometimes made the joining part which joined the substantially C-shaped tube of FIG.   FIG. 2 is an enlarged partial reference diagram of a portion between CC in FIG. 1. This is a form in which the substantially C-shaped tube is annularly joined from one to the other, and the joint portion obtained by annularly joining the substantially C-shaped tube shown in FIG. FIG.   It is a reference perspective view which shows the form at the time of making the joining part joined to the annular | circular shape of this tube of the substantially C-shaped tube with a cut into one and the other.   It is the reference perspective view which shows the form at the time of joining the joint part which was sometimes made to the one and the other shown in FIG. 8 to the annular tube.   It is a reference perspective view which shows the form at the time of mounting | wearing with the substantially C-shaped tube with a cut | disconnection inside the tire of a wheel (1).
