Abstract

The present invention provides a rod-shaped tube that can be replaced by simply removing one side of a tire from a wheel when a bicycle fork or motorcycle rear wheel is punctured. A bicycle fork cut in the middle or a tube in which a tube for a motorcycle is closed in a bag shape, and a rod-like tube 1 having a convex line or a white line 2 over the entire circumference in the longitudinal direction, A fin that is hooked to the air inlet so that it does not come off during construction was attached to the opposite side of one end with the air inlet hole.

Description

  The present invention is a tire tube in which the tube is cut in the middle and the both ends of the tube are closed in a bag shape, the end connection method of the tire tube, the ease of attachment, and the tube breakage prevention measures after puncture It is about.

  Conventionally, both ends of a rod-shaped tube are fixed with a magic tape, or simply attached with both ends attached.

Problems that the device tries to solve

There were the following problems.
When replacing the rear wheel tube of an automobile or motorcycle, it is necessary to remove all of the chain, brake equipment, etc., and it takes a lot of time and labor, and when the tube made into a rod shape is fitted into the wheel, the tube twists to the wheel It was difficult to fit and the tube ends were not securely connected or fixed. If you fork puncture, when you push the punctured bicycle or motorcycle by hand and take it to the repair shop, one end of the tube overlaps with the other end of the tube due to friction between the tire and the tube, and the tube is damaged. It was.
The present invention has been made to solve these problems.

Means for solving the problem

First, in order to make it easy to attach the tube to the wheel, a white line is put in the longitudinal direction of the tube to prevent the tube from twisting into the wheel.
The opposite side of the fixed end close to the air inlet is hooked on the air inlet as shown in FIG. 1 so as not to be separated from each other. A long fin is attached to the opposite side of one end with an air inlet, and when a punctured bicycle fork or motorcycle is pushed, one end of the tube slides on the lower side of the other tube without complicated overlap. .

Effect of device

  When the tube was fitted to the wheel, it was able to be fitted in a certain direction without twisting, and one of the tubes was hooked on the air inlet, so the fixation was secure. When the fork was punctured, one end of the tube overlapped in a complicated manner, preventing it from entering the tube at the other end.

  It is a front view which shows the white line and convex line which were attached | subjected to the perimeter of the tube.   It is a front view which shows the rubber fin attached in order to hook on an air inlet.   It is sectional drawing which shows the concave bump attached to the opposite side to the convex bump attached to the end of a tube.   FIG. 4 is a front view of a drawing in which one end of the air inlet not provided with the metal fitting is punctured, and when it is pushed and moved, the tire and the tube are frictionally overlapped and bent into the direction with the metal fitting.

When the white line 2 is inserted in the side surface of the tube 1 in the longitudinal direction over the entire circumference and the wheel and tire tube are assembled, the white line is set in one direction to prevent twisting of the tube.
The color of the white line attached to the tube may be any number, and paint or another material may be attached to the tube.

A fin 3 having a round hole 4 to be hooked on the air inlet side of the tube 1 is attached to the other end 4 of the tube to ensure mutual fixation.
The fin 3 is preferably made of the same material as that of the tube or a material that can be stretched and contracted with a material that can be easily attached to the tube.

When punctured, the stretched tube enters under the side with the air inlet and does not overlap in a complicated manner. (See Figure 4)
The length of the fin is desired to be at least about 15 cm, and it is preferable that the fin is welded to the back of the rubber plug 6 for fixing one end of the rod-shaped tube.

  When using the present invention, lift the bicycle or motorcycle rear wheel on a stand, etc., first remove the tire from the wheel over the entire circumference with a lever, etc., pull out the old tube from the wheel and cut it with scissors etc. . Next, as opposed to removing the new tube, first insert the tube with the air inlet from the inside into the hole of the wheel, and insert it between the wheel and the tire so as not to twist while looking at the white line of the tube, and finally Insert the finned end tube into the air inlet, complete the method by fitting the tire of the disengaged method into the wheel and injecting air into it, and attach a convex bump to one end of the rod-shaped tube and the other end It is a devise for installation with fins that have holes to be drawn there, and when the air is turned in, the tube will rotate naturally.

Claims (4)

  Bicycle and motorcycle tubes cut in the middle and tubes with both ends closed in a bag shape are provided with a convex line or a white line over the entire circumference in the longitudinal direction to prevent twisting during construction. Stick-shaped tube.   A rod-shaped tube attached to the other end with a fin-like object that is hooked to the air inlet so that the tube does not come off during construction.   2. A rod-shaped tube with a plate-like fin as shown in FIG. 2 attached to one end of the tube and a fin with a hole to be hooked to one end of the opposite closed tube.   When the tube is punctured, a rod-like tube with a long fin is attached so that the tube without the air inlet smoothly enters the lower side of the other end.
