Abstract

PURPOSE:To uniformize a bending stress in a cleat part as well as to avoid any stress concentration by forming a specific flat surface on a tread part of the cleat part attached to a shoe body, while making up a sectional form of the cleat part into such a form as to consist of a specific curve or the like. CONSTITUTION:In the central part of a shoe body 2, there is provided with a fitting part 3 to which a cleat part is attached. In addition, in this fitting part 3, there is provided with an incline 6. Likewise, a tread part 5 is formed at the tip side of the cleat part 1, and a holding fitting 7 is attached to an installed outer circumferential surface 1a. In the above constitution, a flat surface having a mean surface pressure not more than 10kg/cm<2> and a specified width D is formed on the tread part 5. When the width and height at the root in the cleat part 1 are set to B and to H, respectively, (H/B) is set to 0.5-2.0. In addition, when optional points in width B and height H are set to (b) and (h), respectively, the cleat part 1 is formed in such a form as to consist of a curve, b=(h/H)<1/2>XB or the like.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The second invention relates to an elastic track shoe that is attached to the belly band of a tractor and is capable of running on paved roads. The present invention relates to an elastic track shoe in which uniform bending stress is generated in any part of the rubber cleat portion, and stress concentration can be avoided.

[Conventional technology]

Conventionally, when transporting using a tractor etc. equipped with a metal belly band,
When running on a paved road, it damages the paved surface and generates noise, so shoes with a belly band covered with an elastic material such as rubber, or track shoes with a ground contact surface made of rubber, etc. are used. Special Publication No. 62-20069, Special Publication No. 6
2-22835).

However, conventional track shoes have a cleat section made of an elastic material such as rubber attached to the surface of the metal shoe body, so when driving on a road surface, the rubber section is easily affected by unevenness of the road surface, etc. In addition to being subjected to impact forces, there were problems such as severe wear and damage, poor durability, and problems such as the cleat part peeling off from the shoe body and falling off.

[Problem that the invention seeks to solve]

Therefore, in order to solve the above problem, the applicant of the present application proposed in Japanese Patent Application No. 1-186033 that the cleat portion l is connected to the fitting portion 3 of the shoe body 2, as shown in FIGS. 6 and 7. An elastic trunk shoe is proposed in which a holding fitting 4 that is detachably engaged with a fitting part 3 of a shoe body 2 is provided on the outer circumferential surface of the shoe body.

Claims (1)

[Scope of Claims] An elastic track shoe comprising a metal shoe body with a fitting part and a rubber cleat part having a rubber cleat tread part and attached to the fitting part of the shoe body. , an average direct pressure of 10 kgf/
If a plane with a width (D) of not more than cm^2 is provided, and the width of the base of the rubber cleat is (B) and the height (H), then (H/B) is 0.5 to 2. 0, and if arbitrary points of the width (B) and height (H) of the base of the rubber cleat are (b) and (h), respectively, then b=√(h/H)×B 1. An elastic track shoe characterized by having a rubber cleat portion having a shape consisting of a curve, a curve outside the curve, and two or more straight lines.
