Registered Utility Model No. 3123771 (see paragraph numbers 0008 to 0009, FIG. 1 and FIG. 7)

  According to the door stopper of Patent Document 1, the opened door can be received by the door-stop main body, and the door knob can be prevented from colliding with the wall surface. Further, by using the wedge body, the door can be fixedly held at an arbitrary open position, and the used wedge body can be stored by being inserted into a storage hole provided in a leg portion of the holder. However, since the door stopper is configured in a three-piece structure with the door-to-door main body and the holder and the wedge body, the overall structure is complicated and the cost is high even though the required function is simple.

  Further, according to the door stopper of Patent Document 1, since the wedge body is freely put in and out of the storage hole, the wedge body can be used when a pedestrian hits the holder or a floor cleaner collides with the holder. Jumps out of the holder and separates, making it easy to lose. Further, since the wedge body is accommodated in the storage hole provided in the holder, the wedge body cannot be enlarged beyond the size of the holder, and there is a problem in practical usability. For example, it cannot cope with a case where the gap between the lower surface of the door panel and the floor surface changes in size. Since the stopper body and the holder are fixed to the floor surface, the door stopper becomes conspicuous when the door is closed, and the atmosphere of the surrounding space where the door stopper is installed is likely to be impaired. There is also a problem in that the wedge body does not function at all when the door-to-door body and the holder cooperate to regulate the opening limit of the door.

The object of the present invention is a two-piece structure composed of a stopper body and a wedge body that can be attached to and detached from the body. The overall structure is simplified compared to a conventional three-piece door stopper, and the manufacturing cost is further reduced. It is to provide a door stopper that requires less.
Although the object of the present invention is detachable with respect to the stopper body, it cannot be separated unless the user has a clear intention when the wedge body is mounted on the stopper body. The object is to provide a door stopper that can reliably prevent separation and loss.
The purpose of the present invention is to improve the usability in practical use by forming the wedge body approximately the same size as the stopper main body, and in the state where it is mounted on the stopper main body, it is possible to cooperatively receive the impact impact of the door. It is to provide a door stopper.
The object of the present invention is a two-piece structure composed entirely of a stopper body and a wedge body. The simple design makes the appearance simple and clean, and it can be installed without a sense of incongruity. It is to provide a door stopper.

  As shown in FIG. 1, one of the door stoppers according to the present invention includes a stopper body 1 fixed to a floor, a wall, and a door surface wall, and a wedge body 2 detachably attached to the stopper body 1.
