Description

Door stopper {door stopper}

The present invention relates to a stopper for a door to prevent the automatic closing by fixing the open door to an arbitrary position, more specifically, it is operated in a one-touch manner, easy to operate and robust, and does not easily deform or break, The door stopper can smoothly perform the door fixing function regardless of the state, can be applied to the door without the door closer, and the maintenance is convenient.

In general, the door stopper is installed in the lower part of the door in which the door closer is installed, and is opened to fix the position after the door is opened so that the door is not closed by frictional force.

1 is a perspective view of a door stopper according to the prior art. As shown in the related art, the hinge plate 104 is formed on the body plate 102 that is fastened and mounted by using a screw (not shown) on the lower door 101 and the bracket 102a formed on the body plate 102. It is made of a support portion 106 that is fixed to be rotatably installed, the end of the support portion 106 is equipped with a rubber (106a) serves to prevent slipping.

In the conventional door stopper having such a structure, the door is opened in an arbitrary position, and the support part 106 is opened using the toe so that the rubber 106a of the support part 106 comes into contact with the bottom surface to open the door. Fix it. To release the fixed state, the door is pushed backward to release the friction between the support part 106 and the floor, and the toe is inserted between the lower part of the door 101 and the support part 106, and the support part 106 is rolled up. .

However, the body plate 102 is strongly fixed to the hinge 104 so that it is not rotated and unfolded by gravity, and when the body plate 102 is to be folded using the toe, it is inconvenient to operate and damage to the upper surface of the shoe may occur. Due to this inconvenience, the user can bend the waist and use the hand for manipulation, which is an unsanitary problem. In addition, there is a problem that is easily broken by the impact of the rotational movement of the support unit 106 when operating using the toe.

In addition, when assembling the support part 106 to the lower part of the door using a screw (not shown), an assembly error may occur and the door may not be fixed. When the bottom surface is uneven, depending on the open position of the door, The door may not be fixed, and as a result of long use, the rubber 106a may be worn, or frictional force may be reduced due to deformation or dust due to impact on use.

Once mounted on the door, if the gap between the support part 106 and the floor is inappropriate or the fixing function is poor due to wear, etc., there is no adjusting device to compensate for this, so the body plate 102 is removed and reattached or new. There is a maintenance problem, such as a replacement.

The door stopper according to the prior art performs the door fixing function by the friction force generated between the support portion 106 and the bottom surface in response to the force acting in the closing direction of the door closer, but the friction force in the door without the door closer Because of this weak fixing function is incomplete there is a disadvantage that can not use the conventional door stopper.

The object of the present invention devised to solve the problems as described above, it is operated in one-touch manner, easy to operate and robust, does not easily deform or break, and can smoothly perform the door fixing function regardless of the state of the floor surface. In addition, the present invention can be applied to doors without door closers and provides a stopper for doors that is easy to maintain.
