Lightweight metal clogs

Abstract

To achieve both lightness and strength / durability in geta (wooden clogs). [Solution] This invention relates to lightweight and high-strength geta (Japanese clogs) made of metal. By utilizing the formability of metal and bending it in a specific direction that efficiently transmits the stress applied during walking to the entire tooth portion, excellent strength is achieved. Furthermore, by adopting a structure in which the sides and bottom of the tooth portion are integrated, excellent durability is achieved. Efficient processing reduces material waste, achieving both lightness and high strength simultaneously, and reducing manufacturing costs. The invention is also included in the scope of the invention even if the base is made of other materials such as wood. The design allows for flexible adaptation to design and application, as the number and arrangement of teeth can be freely set from one to multiple.

Description

Technical Field

[0001] The present invention relates to sandals, and particularly to sandals that use a metal material to reduce manufacturing costs while maintaining light weight and sufficient strength.

Background Art

[0002] Conventional sandals are mainly made of wood, which is lightweight but cannot exhibit sufficient strength and durability against the stress applied during walking, and there is a problem that they need to be frequently replaced.

[0003] Also, there are sandals made of metal, but there is a problem that their weight increases and excessive burden is imposed on the feet during long-term use.

[0004] Furthermore, since the processing methods of metal materials are limited, the freedom of design and molding is low, and the manufacturing cost tends to be high.

[0007] The present invention utilizes the formability of metal materials and performs bending processing in a specific direction to achieve light weight while having excellent strength and durability against the stress applied during walking, and at the same time realizes cost reduction in manufacturing by optimizing the material usage efficiency.

[0008] By adopting a structure in which the side surface and the bottom surface of the tooth part are integrated, it is lightweight while having high strength and durability. Furthermore, with this structure, it is possible to provide a product that can withstand long-term use.

[0009] By using bending processing of sheet metal, the material is efficiently used, realizing cost reduction in manufacturing and improvement in the degree of freedom in forming. In addition, due to the structure in which the side surface and the bottom surface of the tooth part are integrated, the number and arrangement of teeth can be freely set from one to multiple, enabling flexible response according to design and application.

[0010] The present invention can flexibly respond to the materials and shapes of the tooth part and the base part, and is applicable to various uses. [Effects of the Invention]

[0011] According to the present invention, there is provided a metal geta in which the side surface and the bottom surface of the tooth part are integrated, and by performing bending processing in a specific direction, excellent strength against the stress applied during walking is realized.

[0012] With this structure, excellent durability is exhibited against external pressure and impact.

[0013] Furthermore, reducing weight and optimizing material usage efficiency can also lead to lower manufacturing costs.

[0014] Furthermore, the high degree of freedom in molding allows for flexible adaptation to a variety of applications and designs.

[0015] Because they are lightweight, they can reduce the strain on your feet during long hours of standing or everyday walking. [Examples]

[0016] The geta (wooden clogs) shown in Figure 2 are formed by bending stainless steel teeth (1), with a thickness of approximately 1 mm. Although there are two teeth, the invention is technically within the scope of the present invention even if other metal materials, thicknesses, or the number of teeth differ. Furthermore, although the base (2) is made of metal, other materials can also be used. [Modes for carrying out the invention]

[0017] In this invention, "specific orientation" refers to an angle close to 90 degrees between the side surface of the tooth and the direction of movement during walking, and generally includes a range of 90 degrees ± 10 degrees. This angle allows stress applied during walking to be efficiently transmitted to the entire tooth, resulting in enhanced strength in the planar direction.

[0018] While it is conceivable to add an auxiliary device between the tooth and the base, this is not mandatory. Since the scope of this invention applies with or without the use of an auxiliary device, specific details regarding auxiliary devices are omitted.

[0019] In this invention, rubber feet can be attached to the bottom surface, thereby improving slip resistance and vibration absorption during walking. However, the main feature of this invention lies in the processing technology of the metal parts, and the attachment of rubber feet is merely a supplementary element. The presence or absence of rubber feet can be freely selected depending on the application and design.

[0020] Although the "thong" is not shown in the drawings of this invention, it has been omitted to simplify the understanding of the invention, and the presence of the thong is taken into consideration in the embodiments. The scope of this invention applies regardless of the presence or absence of the thong.

[0021] Furthermore, screw holes and welding points for fixing the base and teeth are not shown in the drawings; this is an omission to simplify the understanding of the invention. The scope of the present invention applies regardless of the presence or absence of these fixing means. The base and teeth can be joined by common methods such as screws, welding, nails, and adhesives. [Brief explanation of the drawing]

Claims

1. A geta (Japanese clog) having a tooth portion and a base portion, wherein the tooth portion is formed by bending iron, stainless steel, aluminum, or an alloy thereof in a specific direction to efficiently transmit the stress applied during walking to the entire tooth portion and maintain strength, thereby simultaneously achieving weight reduction, improved strength, improved durability, and reduced manufacturing costs through optimized material usage efficiency.

2. The geta (wooden clog) according to claim 1, characterized in that the thickness of the teeth is in the range of 0.5 mm to 8 mm, thereby achieving both strength and flexibility.
