Description

TECHNICAL FIELD The present invention relates to a door stopper, and more particularly to a door stopper suitable for a hinged door made of metal (mainly made of a magnetic material such as iron) whose door itself tends to be heavy.

Various types of so-called door stoppers have been proposed to keep the hinged door open, but most of them have a wedge-shaped stopper arranged on the underside of the opened door. For this reason, there is a possibility that the door stopper may come off by catching your foot, or you may stumble and fall.

In view of such circumstances, Patent Literature 1 proposes a door stopper having a structure that does not protrude toward the opening side of the door, that is, toward the passageway. Specifically, it consists of a mounting portion that is fixed to the door stop and a rising portion that faces the opposite side of the door to the aisle side, and a magnet that attracts the metal door is attached to the rising portion. ing.

With such a door stopper, the door stopper does not protrude toward the aisle of the opened door, and it is possible to avoid catching and stumbling. In addition, since the door itself does not need to be processed, there is no risk of impairing its beauty.

Utility Model Registration No. 3207462

However, the door stopper disclosed in Patent Document 1 needs to be fixed to the doorstop in advance, and if it is installed, the doorstop loses its raison d'etre. Further, depending on the weight or surface properties of the door, there is a possibility that sufficient adsorption force cannot be obtained and the open state of the door cannot be maintained. Furthermore, there is also the problem that it cannot be applied to anything other than iron doors.

Therefore, the present invention provides a door stopper that can avoid causing stumbling, can be applied to heavy doors and doors other than iron, and can eliminate the need for prior fixing to the door stop. intended to

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of a door stopper of the present invention will be described in detail with reference to the drawings. First, the structure of the door stopper according to the present embodiment will be described with reference to FIGS. 1 to 3. FIG. 1 is a perspective view of the door stopper according to the embodiment, FIG. 2 is a plan view of the same, and FIG. 3 is a front view of the same.

[composition]
The door stopper 10 according to the present embodiment is basically composed of a first portion (hereinafter referred to as base portion 12) and a second portion (hereinafter referred to as door pressing portion 14). The base portion 12 is a plate-like member that is horizontally arranged in use, and has an engagement groove 12a (first engagement groove) for a door stop 32 attached to the hinged door 30 . The engagement groove 12a may have any specific form as long as the door stop 32 can be inserted thereinto. In the form shown in FIGS. 1 to 3, a notch having a width larger than the diameter of the support 32a of the doorstop 32 is formed, and the tip of the notch is formed in a semicircular shape. By forming the engagement groove 12a in this manner, it is possible to improve the engagement with the columnar support 32a.

The door pressing portion 14 is a plate-like member that is vertically provided at one end of the base portion 12 . An adsorption member 16 (first adsorption member) that enables adsorption to the door 30 is attached to the plate surface of the door pressing portion 14 . In this embodiment, it is assumed that the door 30 is made of metal (for example, metal made of a magnetic material such as iron), and that the attracting member 16 is a magnet. In the door stopper 10 according to the present embodiment, the suction member 16 is attached to the side surface on which the base portion 12 protrudes, that is, the side surface facing the door 30 to be attached. With such a configuration, the adsorption member 16 comes into direct contact with the door 30 . Therefore, even if the attracting member 16 is not a magnet but an elastic material having adhesiveness such as a low-voltage insulating adhesive sticker (trade name: Fisco International Inc.), the attracting force to the door 30 can be obtained. Further, when the attracting member 16 is a magnet, even if the member constituting the door pressing portion 14 is a member other than a magnetic material, a strong attracting force can be obtained with respect to the door 30 made of a magnetic material. can be done.

In the door stopper 10 having such a configuration, a thickness margin d (first thickness) larger than the thickness of the door 30 to be attached is provided between the engaging groove 12a in the base portion 12 and the attracting member 16 of the door holding portion 14. ) are provided. In addition to the thickness of the door 30, the thickness of the cushioning member 32b provided on the doorstop 32 and the like are taken into consideration for the distance of the thickness margin d.

In the embodiment shown in FIGS. 1 to 3, both the base portion 12 and the door holding portion 14 are rectangular in shape, and the base portion 12 has an engaging groove 12a and the door holding portion 14 has an attracting member 16. However, the shape of both the base portion 12 and the door pressing portion 14 is not limited to a rectangle.

[Action/Effect]
The door stopper 10 configured as described above is applied to a hinged door having a door stop 32 as shown in FIG. 5(A). More specifically, it is desirable to apply the door 30 made of a heavy magnetic material such as iron. First, the door 30 is opened as shown in FIG. 5(B). Next, as shown in FIG. 5C, the door stop 32 is fitted into the engaging groove 12a of the base portion 12. Then, as shown in FIG. At this time, the door pressing portion 14 is arranged so as to contact the outer side surface of the door 30, that is, the side surface located on the passage side (the side surface opposite to the side surface facing the door stop 32).

When the door stopper 10 is arranged in this manner, the door pressing portion 14 is attracted to the door 30 by the action of the attracting member 16 (for example, magnetic force when the attracting member 16 is a magnet and the door 30 is made of iron). Positioning is done. Therefore, even if there is a gap between the door 30 and the floor as shown in FIG. 3, the arrangement can be maintained. Here, if the adsorption force of the adsorption member 16 to the door 30 cannot be obtained, the door stopper may be tilted in an unstable state as shown in FIG.

A thickness margin d is provided between the attracting member 16 and the engagement groove 12a in consideration of the thickness of the door 30 and the thickness of the cushioning member 32b of the door stop 32. As shown in FIG. Therefore, the base portion 12 can fit the door stop 32 into the engagement groove 12 a with the door 30 interposed between the door pressing portion 14 and the door stop 32 .

By applying the door stopper 10 according to the embodiment in this way, even if the door 30 is heavy, the door 30 can be kept open without the door stopper 10 coming off. In addition, since the engagement with the door stop 32 can be achieved simply by inserting the post 32a of the door stop 32 through the opening of the engagement groove 12a provided on the side of the base portion 12, the door stopper 10 can be removed when not in use. can be done. Further, on the side surface of the door 30 on the side of the passage, there are arranged only the door pressing portion 14 which is a plate-like member and the adsorption member 16 which is similarly formed in a plate-like or film-like shape. Therefore, even when the door stopper 10 is used, the door 30 hardly protrudes toward the passage. Therefore, there is no possibility that the door stopper 10 will drop off due to hooking or fall due to tripping.

Furthermore, since the door stopper 10 according to the embodiment is configured to prevent the door 30 from closing by arranging the door pressing portion 14 on the passage side of the door 30, the adsorption force of the adsorption member 16 is at least as high as that of the door stopper 10. It is sufficient if it is a degree that can achieve the positioning. Therefore, depending on the selection of the attracting member 16, the present invention can be applied not only to a heavy door made of a magnetic material such as iron but also to a door made of a material other than a magnetic material.

Further, since the door stopper 10 according to the embodiment is positioned by attracting the door holding portion 14 to the lower end portion of the door 30 , the base portion 12 can be engaged with the high position of the door stop 32 . Therefore, there is no need to lengthen the door pressing portion 14 more than necessary or to change the length of the door pressing portion 14 according to the gap between the door 30 and the floor.

[Modification]
As described above, the door stopper 10 according to the embodiment can change the length of the base portion 12 (especially the length of the thickness allowance d) depending on the thickness of the door 30 . Therefore, as shown in FIG. 6, when the thickness of the door 30 to be applied is thin, it is desirable to shorten the length of the thickness allowance d. This is because the open state of the door 30 can be maximized by appropriately determining the length of the thickness margin d.

Further, in the above-described embodiment, the adsorption member 16 is arranged inside the door pressing portion 14, that is, on the side where the base portion 12 protrudes. You can do it. Adhering the adsorption member 16 to the outside of the door pressing portion 14 allows the door pressing portion 14 to be interposed between the adsorption member 16 and the door 30 . Therefore, it is possible to prevent the adsorption member 16 from being peeled off due to the adsorption force of the adsorption member 16 when the door pressing portion 14 is moved away from the door 30 .

In the above-described embodiment, the engagement groove 12a is provided in the base portion 12 as the first portion, and the adsorption member 16 is provided in the door pressing portion 14 as the second portion. The engagement groove 14a (second engagement groove) may be provided on the second member side, and the adsorption member 18 (second adsorption member) may be provided on the first member side. Further, in such a configuration, it is preferable to change the lengths of the thickness margin d and the thickness margin d1. With such a configuration, the functions of the first portion (base portion 12) and the second portion (door holding portion 14) are exchanged, so that one door stopper 10 can handle doors 30 of at least two thicknesses. This is because it becomes possible to

In the drawings, the engaging grooves 12a and 14a both have a straight structure, but they may be hooked on the door stop 32 by widening the width of the tip end side, for example.
