HINGE STRUCTURE

Abstract

A hinge structure includes two leaves with locking holes and a pivot adapted to be in connection with the two leaves, where each leaf is made of polymer composite carbon fiber and pivot is a pivoting piece made of aromatic polyamide curtain fabric, where the pivoting piece is sandwiched between the two leaves and bonded together therewith by means of thermosetting molding to form a sheet body. The present invention is silent without needing maintenance, labor-saving in door opening and closing, long in hinge life, light-weighted in weight, thin in thickness and good in strength.

Claims

1. A hinge structure, comprising two leaves with locking holes and a pivot adapted to be in connection with said two leaves, wherein each said leaf is made of polymer composite carbon fiber and pivot is a pivoting piece made of aromatic polyamide curtain fabric, wherein said pivoting piece is sandwiched between said two leaves and bonded together therewith by means of thermosetting molding to form a sheet body.

2. The structure according to claim 1, wherein each said leaf is made of polymer composite carbon fiber by means of warp and weft weaving to form a layer structure, and said pivoting piece is sandwiched and connected fixedly between said two layers.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0010] FIG. 1 is a schematically perspective view of a conventional hinge;

[0011] FIG. 2 is a schematically perspective view of a hinge structure according to the present invention; and

[0012] FIG. 3 is a partly enlarged view of FIG. 2.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Referring to FIGS. 2 and 3, a hinge structure of the present invention includes two leaves 1 respectively having locking holes 11 and a pivot in connection with the two leaves 1, where the leaf 1 is made of polymer composite fiber, and pivot is a pivoting piece 2 made of aromatic polyamide curtain fabric, and sandwiched between the two leaves 1 and combined therewith by means of thermosetting molding.

[0014] Each leaf 1 is made of polymer composite carbon fiber by means of warp and weft weaving to form a layer structure, and the pivoting piece 2 is sandwiched and fixed between the two layers.

[0015] The connection function of the leaves 1 of the hinge can be satisfied because polymer composite carbon fiber has a light weight and high strength. In addition, the pivoting piece 2 formed of aromatic polyamide curtain fabric also has a light weight, flexibility and good toughness, capable of realizing the pivot function, thereby achieving the surface joining effect.

[0016] The hinge structure according to the present invention has the following advantages compared with conventional hinge structures:

[0017] 1. the leaf 1 of the hinge is light-weighted and strong because it made of obviously light-weighted polymer composite carbon fiber (compared with metal). In addition, the hinge is silent upon surface joining without needing maintenance (the addition of lubricant), labor-saving upon door opening and closing, and long in life.

[0018] 2. the hinge so-made completely is a sheet body, small in volume, light in weight, thin in thickness, suitable for the joining of objects with a small gap between them, and flexible and convenient for application because the pivoting piece 2 made of aromatic polyamide curtain fabric is used to be in connection with the leaves 1.
