Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a wedge-shaped door stopper that is disposed between a lower edge of a hinged door, particularly a hinged door having a gradual closure, and a floor to hold the hinged door in an open state.

[0002]

[Prior art]

 Conventionally, a wedge-shaped door stopper has been used as a means for keeping a door, particularly a door with a gradual closure (hereinafter simply referred to as a “door”) in an open state when performing ventilation, cleaning, loading / unloading, etc. ing. The wedge-shaped door stopper 51 has an inclined surface 52a on the upper surface with which the sliding door lower edge 54a abuts as shown in FIGS. 7 and 8, and the frictional force generated between the lower surface of the wedge-shaped door stopper 51 and the floor 55 causes The door 54 is used to prevent the door 54 from closing, and is mainly made of synthetic resin or synthetic rubber having a large friction coefficient and easy elastic deformation.

[0003]

[Problems to be solved by the invention]

 The wedge-shaped door stopper 51 can be used if it has a height equal to or greater than the distance h between the door lower edge 54a and the floor 55, but depending on the contact position between the inclined surface 52a and the door 54 as shown in FIG. The following problems arise. When the hinged door 54 comes into contact with the inclined surface 52a at the lower portion 52m in the inclined direction of the wedge-shaped door stopper 51, an uneven load is generated on the lower surface of the wedge-shaped door stopper 51, and the frictional force with the floor 55 is reduced. The hinged door 54 moves easily. When the hinged door 54 comes into contact with the inclined surface 52a at the upper portion 52n in the inclined direction of the wedge-shaped door stopper 51, the frictional force between the lower surface of the wedge-shaped door stopper 51 and the floor 55 is reduced, and the wedge-shaped door stopper 51 is reduced. The wedge-shaped door stopper 51 easily rolls around the two-sided joint 52k between the lower surface and the back surface of the door stopper 51 due to the bending moment received from the hinged door 54. Therefore, especially when there are many occasions of use in different places such as a cleaning business, wedge-shaped door stoppers of various sizes suitable for each swing door are required, which has caused problems in cost and management. In the case of, as shown in FIG. 10, when the same type of wedge-shaped door stoppers 51, 51 are used one above the other, the hinged door 54 can be brought into contact at an appropriate position on the inclined surface 52a. If the inclination angle r is large, the horizontal force that the inclined surface 52a receives from the hinged door 54 increases, so that the upper wedge-shaped door stopper 51 is easily displaced, so that not only the hinged door 54 cannot be stably held, but also for installation work. Requires extra time and effort.

The present invention has been made in view of such a situation. By making it possible to select an inclination angle according to the installation state of a hinged door, it is possible to prepare a plurality of wedge-shaped door stoppers even when used in different places. An object of the present invention is to provide a wide-range wedge-shaped door stopper that can hold each hinged door at an appropriate position on an inclined surface.

[0005]

[Means for Solving the Problems]

 The inventor of the present invention has made intensive studies to solve the above-mentioned problems. As a result, if two wedge-shaped stopper members are connected so as to be relatively rotatable in the vicinity of the two-face joint between the lower surface and the back surface of each wedge-shaped stopper member, the following problem is obtained. We found that two or more types of inclination angles could be selected with each wedge-shaped door stopper, and completed the present invention.

That is, according to the present invention, two wedge-shaped stopper members having an inclined surface provided with a non-slip surface on the upper surface, and these two wedge-shaped stopper members are provided in the vicinity of a two-surface joint between the lower surface and the back surface of each wedge-shaped stopper member. A connecting member for connecting the two wedge-shaped stopper members, wherein the lower surfaces of the two wedge-shaped stopper members are in contact with the installation surfaces and one of the wedge-shaped stopper members is used. (2) A wedge-shaped door stopper characterized in that both wedge-shaped stopper members are configured to be relatively rotatable via the connecting member in order to change the posture between the two use postures. In such a wedge-shaped door stopper, since the distance between the lower edge of the door and the floor is large, when the door stopper is used in the first use posture, the lower edge of the door is inclined at an upper portion in the inclination direction of the one wedge-shaped stopper member. When the door comes into contact with the surface, the door can be brought into contact with an appropriate position of the upper stopper member by changing to the second use posture. In the second use posture, the frictional force with the installation surface, that is, the floor, is increased by the inclined surface provided with the anti-slip, which is located on the bottom surface, and the connecting member for connecting both stopper members is further provided. As a result, the relative movement of the two stopper members is restricted, so that a stable posture is maintained.

Here, an engaging portion projecting outward is provided on the lower surface of one wedge-shaped stopper member of the two wedge-shaped stopper members, and the two wedge-shaped stopper members are engaged with the engaging portion on the lower surface of the other wedge-shaped stopper member. It is preferable in terms of stability of the second use posture that an engaged portion for fixing the stopper member in the second use posture is provided.

In addition, it is preferable from the viewpoint of manufacture that a thin plate-shaped member is used as the connecting member, and the thin member and the two wedge-shaped stopper members are integrally formed of synthetic resin or synthetic rubber.

Further, it is preferable that both wedge-shaped stopper members are hollow-formed so as to have a space inside. By providing the space in this manner, the elastic deformation of both stopper members is facilitated, the biting force on the hinged door is increased, the hinged door can be more firmly fixed, and the material cost can be reduced.

The two wedge-shaped stopper members each have an opening that opens downward, and a plurality of ribs extending from one side wall to the other side wall and ribs orthogonal thereto are provided inside the two wedge-shaped stopper members. It is preferable to provide it substantially coincident with the lower surface of the member. By providing the opening as described above, the two wedge-shaped stopper members can be easily elastically deformed, and a plurality of ribs are provided so that the lower edges thereof substantially coincide with the lower surface of the wedge-shaped stopper member. Even if the members are not excessively deformed and the side walls of the upper and lower wedge-shaped stopper members are displaced from each other in the width direction due to elastic deformation when used in the second use posture, the side walls are not deformed. Since the end faces abut against the lower edges of the ribs and do not fall into the openings, a stable holding state can be maintained.

It is preferable that a plurality of ridges extending in the width direction of the inclined surface are provided at equal intervals throughout the longitudinal direction of the inclined surface as slip stoppers provided on the inclined surface. According to this, when supporting the hinged door on the inclined surface provided with the ridge, the ridge bites the lower edge of the hinged door, and the hinged door is firmly fixed, and the frictional force with the floor in the second use posture is also reduced. Increase.

An upper plate portion 2b configured in a slanted posture, a rear plate portion 2c that is obliquely lowered from the rear end of the upper plate portion 2b, and a pair of side plate portions 2d that hang down directly from both ends of the upper plate portion 2b; 2d, and openings 2e are formed below as shown in FIG. As the non-slip provided on the inclined surface 2a, a plurality of ridges 6... Extending in the width direction of the inclined surface 2a are formed at equal intervals throughout the longitudinal direction of the inclined surface 2a. Here, it is effective to form the ridges 6 at an angle to the width direction of the inclined surface or to form the ridges 6 in a curved shape, and it is also effective to form a large number of truncated cone-shaped protrusions. Is also effective.

The wedge-shaped stopper members 2 and 2 and the connecting member 3 are integrally formed of synthetic resin or synthetic rubber. Since the wedge-shaped stopper members 2, 2 have the openings 2e,..., Ie, the spaces 2f,... And the hinged door 4 can be fixed more strongly.

Inside each of the wedge-shaped stopper members 2, a plurality of first ribs (three in the figure) 7 extending between the inner surfaces of the side plate parts 2d, 2d and these first ribs (three in the figure) The second ribs 8 connecting the central portions of the pieces 7... Are provided such that the lower edges of the ribs substantially coincide with the lower surfaces of the wedge-shaped stopper members 2. As a result, the wedge-shaped stopper members 2 made of synthetic resin or synthetic rubber can be elastically deformed while the shape retaining force can be increased. In this case, as shown in FIG. 5, even if the end surfaces of the side walls are displaced from each other in the width direction, the end surfaces of the side walls may come into contact with the lower edges 7 'of the first ribs and fall into the openings 2e. Because it is not, a stable posture can be maintained.

The connecting member 3 is a plate-shaped thin member made of synthetic resin or synthetic rubber integrally formed with the two wedge-shaped stopper members 2, 2, and the two wedge-shaped stopper members 2, 2 are connected via the connecting member 3. 2 is configured to be relatively rotatable. Therefore, the wedge-shaped stopper members 2 and 2 come into contact with the floor 5 as shown in FIG. 1, and the wedge-shaped stopper member 2 holds the hinged door 4 from the first use posture. The bottom surfaces of the stopper members 2 are joined to each other so that the two wedge-shaped stopper members 2 can easily change the posture to the second use posture in which the opening door 4 is held. By making the posture changeable in this way, the wedge-shaped door stopper 1 can abut on the hinged door 4 at an appropriate position on the inclined surface 2a. The connecting member 3 can easily separate the two wedge-shaped stopper members 2 and 2 or cut them off with a cutter or the like, and each wedge-shaped stopper member 2 can be used alone as a wedge-shaped door stopper. . For example, the connecting member shown in FIG. 6 is also effective. This is provided integrally with one wedge-shaped stopper member 2 and provided with an engaging portion 11 which is detachably engaged with the other wedge-shaped stopper member 2. Each wedge-shaped stopper member 2 is provided only when necessary, for example, when a hinged door is narrowly installed. Can be used alone. In this embodiment, the two wedge-shaped stopper members have the same shape and the same size. However, the present invention is not limited to this. For example, the inclination angles of the two wedge-shaped stopper members are different, so that the first wedge-shaped stopper member can be used in the first use posture. A total of three types of inclination angles can be selected by combining the two types and the second use posture, and the lower edge of the hinged door can be brought into contact with a more appropriate range of the inclined surface, further expanding the applicable range for the hinged door. Can be.

As shown in FIG. 3, one of the two wedge-shaped stopper members 2, 2 has a protruding portion projecting outward from the inner surface of the upper plate 2 b near the tip of the wedge-shaped stopper member 2. In the other wedge-shaped stopper member 2, concave portions 10, 10 for engaging with the convex portions 9, 9 to fix the stopper members 2, 2 in the second use posture are formed. Has formed. Therefore, each wedge-shaped stopper member 2 in the second use posture hardly moves relatively due to the engagement of the connecting member and the irregularities, and can maintain a stable posture. However, in the present invention, the projections 9 and 9 and the depressions 10 and 10 may not be provided.
