Strap holder for mobile devices

Abstract

This invention provides a strap holder for mobile devices that suppresses stress concentration around metal components, wear and fraying of the base material edges, and tearing due to repeated loading, thereby improving durability and usability. [Solution] A strap holder for a mobile device comprises a base material 1 that is sandwiched in a mobile device case and a metal member 2 for connecting a strap, wherein a cylindrical reinforcing member 3 is placed at the contact portion of the metal member 2 with the base material, and a heat-shrinkable tube 4 is placed on at least a part of the base material 1. Conventional structures had the problem that the base material was prone to deterioration due to repeated putting in and taking out of pockets and repeated pulling of the strap during daily use.

Description

Technical Field

[0001] The present invention relates to a strap holder for a mobile terminal that is used by being attached to a mobile terminal case.

Background Art

[0002] Conventional strap holders generally have a structure in which a metal member is attached to a base material such as non-woven fabric.

[0003] However, in the conventional structure, stress concentration around the metal member, wear at the end of the base material, fluffing due to long-term use, and tearing due to repeated loads may occur.

[0004] Also, in daily use, there is a problem that the deterioration of the base material tends to progress due to putting in and taking out of the pocket and repeated pulling of the strap.

Summary of the Invention

Problems to be Solved by the Invention

[0005] An object of the present invention is to suppress wear during long-term use, fluffing at the end of the base material, tearing due to repeated loads, stress concentration around the metal member, etc., and to improve durability and usability in daily use.

[0006] Another problem is to reduce the sense of discomfort during mobile terminal operation by reinforcing the base material while maintaining flexibility.

Means for Solving the Problems

[0007] The strap holder for a mobile terminal of the present invention includes a base material 1 sandwiched between a mobile terminal case and a metal member 2 for connecting a strap.

[0008] A cylindrical reinforcing member 3 is disposed at the base material contact portion of the metal member 2.

[0009] The cylindrical reinforcing member 3 suppresses direct contact between the metal member 2 and the base material 1, and alleviates stress concentration that occurs around the metal member 2.

[0010] Furthermore, a heat-shrinkable tube 4 is placed on at least a portion of the base material 1 to suppress wear, fraying, and tearing of the base material edges due to repeated loading. [Effects of the Invention]

[0011] According to this invention, by arranging the cylindrical reinforcing member 3 at the contact portion of the metal member 2 with the base material, direct contact between the metal member 2 and the base material 1 is suppressed.

[0012] This reduces stress concentration around the metal member 2, thereby suppressing wear, fraying, and cracking of the base material 1.

[0013] Furthermore, by placing the heat-shrinkable tube 4 on at least a portion of the base material 1, the edges of the base material are protected, thereby improving durability during long-term use.

[0014] Furthermore, by reinforcing the device while maintaining its flexibility, it is possible to reduce discomfort when operating a mobile device. [Brief explanation of the drawing]

[0016] The embodiments of this invention will be described below with reference to the drawings.

[0017] The strap holder for a mobile terminal of the present invention includes a base material 1 sandwiched between mobile terminal cases and a metal member 2 for connecting a strap.

[0018] A cylindrical reinforcing member 3 is disposed at the base material contact portion of the metal member 2.

[0019] Thereby, direct contact between the metal member 2 and the base material 1 can be suppressed, and stress concentration generated around the metal member 2 can be alleviated.

[0020] Further, a heat shrinkable tube 4 is disposed on at least a part of the base material 1.

[0021] Thereby, wear, fraying, and tearing due to repeated loads at the end of the base material 1 can be suppressed.

[0022] Furthermore, by performing reinforcement while maintaining the flexibility of the base material 1, it is possible to reduce the discomfort during mobile terminal operation.

[0023] As the base material 1, non-woven fabric, woven fabric, resin sheet, etc. can be used.

[0024] As the cylindrical reinforcing member 3, a resin tube, a metal pipe, etc. can be used.

[0025] [[]]As the heat shrinkable tube 4, a polyolefin-based heat shrinkable tube, etc. can be used.
