Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a door stopper capable of keeping a revolving door open.

[Conventional technology]

If you want to keep a pivoting door open during the summer, conventionally, you would insert a wedge-shaped wooden board into the gap between the bottom of the pivoting door and the floor. , keeping the door open.

[The problem that the idea aims to solve]

However, in the conventional method, the distance between the bottom surface of the door and the floor varies depending on the rotating door, so the size of the wedge-shaped wooden board in side view is adjusted according to this distance. The problem was that the same size wooden board could not be used for all doors. In addition, on wooden boards,
Since the frictional force with the floor surface is small, there is a problem in that it is difficult to keep the door open against the rotational force of the door.

The present invention has developed a door stopper that can easily adjust the height of the door stopper according to the distance between the bottom surface of the rotating door and the floor, and that can also reliably keep the door open. is intended to provide.

[Means to solve the problem]

In order to achieve such an object, the door stopper of the present invention is a wedge-shaped plate body when viewed from the side, and has protrusions and recesses for fitting on the upper and lower surfaces so that a plurality of plates can be stacked vertically. Further, the lower surface is made horizontal, the upper surface is an acutely inclined surface, a convex portion is provided at the upper end of the slope, and a concave portion that can fit into the convex portion is provided on the lower surface so that a plurality of pieces can be stacked in the vertical direction. It is preferable to have one provided. Further, for the effects described later, it is preferable to use a device provided with anti-slip ridges on the upper and lower surfaces, or a device made of soft synthetic resin.

[Effect]

Depending on the distance between the bottom surface of the rotary door and the floor surface, the wedge-shaped tip of the door stopper of the present invention is formed by vertically stacking two or more door stoppers by fitting the fitting convex part and the concave part. The door can be kept open by inserting it into the gap between the bottom surface of the door and the floor from the direction opposite to the rotation direction of the door while the door is open. If the gap between the bottom surface of the door and the floor is small, a single door stopper can be used.

〔Example〕

The details of the invention will be further explained by means of illustrated embodiments. The drawings show an example of an embodiment of the present invention, and FIG. 1 is a perspective view of a door stopper;
Figure 2 is a top view, Figure 3 is a bottom view,
FIG. 4 is a sectional view taken along the line A-A in FIG. 2.

The door stopper A is a wedge-shaped plate made of soft synthetic resin such as polypropylene resin, and as shown in FIG. 1, the lower surface 1 is horizontal and the upper surface 2 is an acutely inclined surface 3. The door stopper A in the figure has a horizontal portion 4 at the upper end of the inclined surface 3.
The door stopper A has a recess on the bottom surface of a size that can fit the protrusion 5, so that a plurality of door stoppers A can be stacked vertically. As shown in Fig. 2, the inclined surface 3 of the door stopper A has a plurality of anti-slip ridges 7 arranged substantially parallel to the bottom edge 8. Furthermore, as shown in Fig. 3, the bottom surface 1 of the door stopper A also has a plurality of anti-slip ridges 7' arranged alternately in pairs, one at a time, substantially parallel to the bottom edge 8. Here, the anti-slip ridges 7,
7' is not limited to the illustrated example.
Any known shape and arrangement may be adopted as appropriate.

Next, as shown in FIG.
By fitting the protrusion 5 provided on the upper surface 2 and the recess 6 provided on the lower surface 1 of the door stopper A, two pieces are stacked in the vertical direction, and the height of the door stopper A, that is, the inclination angle of the inclined surface 3, is It can be adjusted according to the distance between the bottom of the rotating door and the floor. Similarly, by stacking a plurality of door stoppers A, the height of the door stopper A, that is, the angle of inclination of the inclined surface 3 can be increased.

Note that the door stopper A is not limited to the above-mentioned door stopper A, and a door stopper having a recess 6 for fitting on the upper surface 2 and a protrusion for fitting 5 on the lower surface 1 may be adopted as appropriate so that a plurality of door stoppers can be stacked in the vertical direction. can do.

As shown in FIG. 6, with the rotating door B open, the lower end 8 of the door stopper A is pressed against the lower surface of the door B in the opposite direction to the rotating direction of the door B, which is indicated by the arrow in the figure. By inserting the door B into the gap between the door B and the floor C, the door B can be kept open. In addition, when the distance between the gap between the lower surface of the door B and the floor surface C is large, by fitting the convex portion 5 provided on the upper surface 2 of the stopper A and the recessed portion 6 provided on the lower surface 1 of the stopper A, The door B is opened by stacking a plurality of door stoppers in the vertical direction and increasing the height of the door stopper A, that is, the angle of inclination of the inclined surface 3, by inserting it into the gap between the bottom surface of the door B and the floor surface C. can be kept in good condition.

According to the door stopper A of the embodiment of the present invention, the convex portion 5 on the upper surface 2 and the recessed portion 6 on the lower surface 1 are fitted, and two or more door stoppers A are stacked in the vertical direction, so that the rotary type Door stopper A is adjusted according to the distance of the gap between the bottom surface of door B and floor surface C.
The height, that is, the angle of inclination of the inclined surface 3 can be easily adjusted. In addition, the door stopper A is made of soft synthetic resin such as polypropylene resin, and is provided with anti-slip protrusions 7 and 7' on the inclined surface 3 and the lower surface 1, so that the lower surface of the door B and the floor surface C are By increasing the frictional force of the door B, the door B can be reliably kept open against the rotational force of the door B. Moreover, since the door stopper A is integrally molded from soft synthetic resin, it has a much better appearance than a conventional wooden board.

[Effect of idea]

Since the present invention is configured as described above,
This produces the following effects.

(1) In the door stopper of the present invention, by stacking a plurality of door stoppers vertically by fitting the fitting convex part and the concave part, the door stopper can be adjusted according to the distance between the bottom surface of the rotating door and the floor surface. The height of the door stopper, that is, the angle of inclination of the inclined surface can be easily adjusted.

(2) Anti-slip protrusions are provided on the top and bottom surfaces, which increases the frictional force between the bottom surface of the door and the floor, making it possible to keep the door open against the rotational force of the door. .

(3) If a soft synthetic resin is used as the material for the door stopper, the frictional force between the bottom surface of the door and the floor surface can be further increased.
