ABSTRACT:

CROSS-REFERENCE TO RELATED APPLICATION
This application claims priority of Korea patent Application No. 2000-70383, filed on Nov. 24, 2000.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a door hinge of vehicles, and more particularly to a door hinge cum door checker of vehicles adapted to serve as door checker eliminating the necessity of installing a separate door checker.
2. Description of the Prior Art
In general, a door
110
of a vehicle is attached to a body
120
at an upper part and at a lower part via door hinges
130
for opening and closing, and is installed at a midsection with a door checker
140
to enable to keep the door
110
to stay at an opened state at a predetermined position, as illustrated in FIG.
1
.
As illustrated in
FIG. 2
, a body member
131
and a door member
132
are coupled via a hinge pin
133
where, the body member
131
and flange
132
a
of the door member
132
are formed with coupling holes
131
a
and
132
b
through which the body
120
and the door
110
are installed via each bolt.
The door checker
140
includes a hinge bracket
141
mounted at the body
120
, a checker bar
142
hinged to the hinge bracket
141
and a checker body
143
mounted at the door
110
for accommodating the other part of the checker bar
142
lest it should be loosened, where the checker bar
142
is formed with a groove
142
b,
as illustrated in FIG.
3
.
When the door
110
is rotated about the hinge pin
133
, the checker body
143
is moved to the left and to the right on the checker bar
142
, where a roller (not shown) in the checker body
143
is moved when the door
110
is opened from a position near an approximate area
142
a
of the hinge bracket
141
while the door is closed, thereby positioning itself at the groove
142
b.
The roller is pushed toward the checker bar
142
by support means (by way of example, a spring) mounted inside the checker body
143
, such that the door
110
where external force is not applied maintains the opened state at a position thereof when accommodated at the groove
142
b.
The door hinge
130
and the door checker
140
, each mounted in between the body
120
and the door
110
, are rotated, closed and opened in a state where the door
110
is installed at the body
120
, and serve to perform a function of maintaining the door
110
to be at the opened state at a predetermined position.
However, there is a problem in that, even though the door hinge
130
and the door checker
140
are all mounted between the body
120
and the door
110
, and are actuated by the same cause of opening/closing operation by the door
110
, the number of assembling process is increased due to their being separated items, and assembling cost thereof is also raised.
SUMMARY OF THE INVNETION
The present invention is disclosed to solve the aforementioned problems and it is an object of the present invention to provide a door hinge cum door checker of vehicles adapted to enable to perform two functions of door checker and door hinge by one part thereby reducing the number of parts and assembling processes and decreasing costs thereof.
In accordance with the object of the present invention, there is provided a door hinge cum door checker of vehicles, wherein the door hinge cum door checker comprises:
a fixation arm having a round body formed at a mounting plate formed with a mounting hole for mounting to a body while the round body is formed at a tip end thereof with a stopper, a hinge pin formed through the round body and the hinge pin formed with a first groove and a second groove;
a rotary arm having an upper arm and a lower arm, each inserted into the hinge pin and each having a steel roller received by the first and second groove of the hinge pin in response to rotating state of a door, and a coupling plate for coupling the upper arm and the lower arm, where mounting holes are formed at the upper/lower arms and at the coupling plate for mounting to the door, while the upper/lower arms are formed at a connecting body thereof with a hitching jaw at which the stopper of the fixation arm is hitched; and
a cap for respectively covering the upper arm and the lower arm of the rotary arm.
