Tire lever

Abstract

To provide a tire lever that can be efficiently accommodated with no gap in a cylindrical accommodation container having a certain curvature.SOLUTION: A tire lever has a shape having a curvature in one or both of a front surface 1 and a back surface 2, the curvature being equal to a curvature of a cylindrical accommodation container. By connecting the tire levers by a connection mechanism 6 provided on a side surface 5 and accommodating them, efficient accommodation with no gap can be achieved.SELECTED DRAWING: Figure 1

Description

Technical Field

[0001] The present invention relates to a tire lever used for detaching a bicycle tire.

Background Art

[0002] A tire lever used for detaching a bicycle tire is widely used as a known technique. In addition, a product provided with a connecting mechanism on both the front and back sides of the main body and connecting a plurality of tire levers in consideration of storage and portability is also a known technique and is widely used.

Summary of the Invention

Problems to be Solved by the Invention

[0003] The present invention aims to solve the inconvenience during carrying, which is a problem in known tire levers. A tire lever provided with a connecting mechanism can be carried without losing a plurality of tire levers and greatly contributes to improving the convenience of users. However, there is a problem when storing the connected tire levers themselves. Especially in a sports bicycle with limited storage space, when storing a rectangular parallelepiped-shaped tire lever in a generally used cylindrical storage container, the poor space efficiency is a major problem.

[0004] An object of the present invention is to provide a tire lever having excellent storage performance and being easy to carry.

Means for Solving the Problems

[0005] The tire lever according to the present invention has a curved shape with a certain curvature provided on the main body and has a shape that can be stored without gaps along the inner wall of a generally used cylindrical storage container. Further, a connecting mechanism for tire levers is provided on the side surface of the main body, and a plurality of tire levers are connected to have a shape that can be stored without gaps along the inner wall of the cylindrical storage container.

Effects of the Invention

[0006] In the present invention, it is possible to store the tire lever in a cylindrical storage container without any gaps, and the limited storage space can be utilized without waste.

[0007] In addition, due to the connection mechanism provided on the main body, a plurality of tire levers do not dissipate within the storage container, so the convenience during retrieval is enhanced.

Embodiments for Carrying Out the Invention

[0009] FIG. 1 shows an embodiment of the tire lever according to the present invention. In FIG. 1, the tire lever is provided with a curvature along the inner wall of the cylindrical storage container on one or both sides of its front surface 1 and back surface 2, and it can be stored without any gaps along the inner wall of the cylindrical storage container.

[0010] FIGS. 2 and 3 show the X-X cross-sectional views in FIG. 1. As shown in FIG. 2, the curvature may be provided on only one side, or as shown in FIG. 3, it may be provided on both sides.

[0011] The curvature provided on one or both sides of the main body desirably conforms to the diameter of the cylindrical storage container generally used in sports bicycles, and including manufacturing errors, it is 74 mm ± 5 mm or 90 mm ± 5 mm in diameter.

[0012] The convex surface of the curvature provided on either one side or both sides of the main body may face either the front or the back side of the tire lever. When the curvature is provided on both sides, both sides may be convex.

[0013] The upper part of the main body has an operating portion 3 that is inserted into the gap between the tire and the rim when removing the tire, and the lower part of the main body has a fixing portion 4 that is fixed to the spokes of the wheel. It can be used for removing the tire in the same way as a general tire lever, and the fixing portion 4 can also be omitted for simplicity.

[0014] A connecting mechanism 6 is provided on the side surface 5 of the main body. The connecting mechanism is formed by any one or a combination of a mechanical fitting shown in the figure, the magnetic force between magnets, or the magnetic force between a magnet and a yoke.

[0015] As shown in FIG. 5, the connecting mechanism may be provided not only on the side surface of the main body but also on the front surface or the back surface of the main body, or both. In this case, as shown in FIG. 6, it is desirable that no unevenness that hinders storage is formed on both sides by the connecting mechanism during connection.

[0016] The material of the tire lever according to the present invention is made of any one of plastic, metal, ceramics, wood, and bamboo, or a composite material of two or more thereof, and has sufficient strength and toughness necessary for removing the tire.
