ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a hinge for connecting two separate apparatuses, and more particularly to a hinge that not only has simple combination process and secured structure but also does not require any assistant tool.
2. Description of the Prior Art
Hinge is used to connect two separate apparatus that share a common axis, and is widespread used in modern industry and daily life. Possible applications comprise door hinge, journal box hinge, gear ox cover hinge and so on.
Conventional structure of hinge, as shown in
FIG. 1
, is essentially formed by torsional spring
10
that one end of torsional spring
10
locates on apparatus
12
and another end of torsional spring
10
locates on apparatus
14
, where apparatus
12
and apparatus
14
shares common axis
16
and shapes of both apparatuses
12
/
14
are unrestricted.
In general, when hinge is formed and opened, then apparatus
12
and apparatus
14
are pre-transfigured with a specific angle and torsional spring
10
is compressed. Where obstruction
18
is formed on axis
16
to prevent apparatus
12
and apparatus
14
are separated by elastic force of compressed torsional spring
10
. Furthermore, when hinge is closed torsional spring
10
is further compressed, then opposite direction torque that induced by further compressed torsional spring
10
will pull hinge back to initial state when external force is vanished.
Obviously, conventional structure of hinge is simple and useful. No matter how, combination process of conventional structure of hinge is strenuous for torsional spring
10
must be pre-transfigured to the specific angle before two ends of torsional spring
10
are located on apparatus
12
and apparatus
14
. Beside, owing to the fact that apparatus
12
, apparatus
14
, axis
16
, and obstruction
18
should be assembled in a specific configuration with the specific angle before they are connected to each other. It is obvious that assistant tools are required to fix position of each component part and compress spring
10
.
According to previous discussion, it is obvious that structure and combination process of conventional hinge are not perfect, and then it is desired to develop an improved structure of hinge that not only provides simple combination process and secured structure but also saves the requirement of assistant tools.
SUMMARY OF THE INVENTION
The main objective of the present invention is to mitigate and/or obviate these previously described disadvantages in the manner set forth in the following description of these preferred embodiments.
A primary object of the present invention is to present a hinge that reduce combination cost by saving the requirement of assistant tools.
Another objective of the present invention is to provide a hinge that simplifies combination process of hinge.
A further objective of the invention is to afford a hinge with a securely structure.
These component parts of the provided hinge comprise a first pair of structures, a second pair of structures and a torsional spring.
Moreover, these component parts of the provided invention have following characteristics:
(1) First pair of structures is fixed on one apparatus, and second pair of structures is fixed on another apparatus.
(2) One pair of structures locates inside another pair of structures.
(3) One bulge locates on one structure of first pair of structures, the bulge is adjacent to second pair of structures.
(4) One concave portion locates on edge of another structure of first pair of structures.
(5) One hook locates on a specific structure of second pair of structures, the specific structure is adjacent to the structure with concave portion.
(6) One end of the torsional spring locates on one apparatus or first pair of structures, another end of the torsional springs locates on another apparatus or second pair of structures.
The combination process of the provided invention can briefly illustrated by following descriptions.
First, torsional spring is coupled with two apparatuses when torsional spring is not transfigured. until first pair of structures is securely coupled with second pair of structures by the hook directly hooking edge of the concave portion.
Further objectives and advantages of the present invention will become apparent as the following description proceeds and the features of novelty which is characterized in these claims annexed to and forming a part of the invention.
