Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a door stop for abutting an end of a door when opening and closing the door.

[Conventional technology]

This type of door stop is provided with rubber or elastic plastic as shown in Japanese Utility Model Laid-Open No. 58-126376 and Japanese Patent Laid-Open No. 64-10181, and is fixedly installed on the floor surface at the open end position of the door. The shock of opening is cushioned by the rubber or plastic bumper.

[Problems to be solved by the device]

In the conventional door stop as described above, since the part for attaching the door stop to the floor is larger than the outer diameter of the bumper part,
When the lower end of the door and the floor surface are close to each other, the attachment part may come into contact with the vicinity of the lower end of the door before the door and the bumper come into contact with each other, which may damage the door. .

Also, because the shapes of the components that make up the door stop differ between when installing on a wooden floor and when installing on a concrete floor, separate products must be prepared for each floor surface, especially for concrete floors. It was necessary to install an anchor bolt separately from the one used.

Further, since the bumper portion made of an elastic material that comes into contact with the door door is fitted and fixed to the main body portion of the door stop, there is a risk that it may come loose during use.

An object of the present invention is to provide a new door stop that solves the above problems in the conventional art.

[Means for Solving the Problems]

The door stop according to the present invention for achieving the above object has an elastic bumper in which a bolt head is embedded and a bolt shaft is projected downward, and a through hole through which the bolt shaft is inserted. A main body supporting the elastic bumper, a female screw hole penetrating through which the bolt shaft is screwed, which is arranged in a lower portion of the main body, and a plurality of countersink holes formed inside the outer periphery of the main body around the female screw hole. The outer diameter of the main body and the mounting seat is substantially the same as the outer diameter of the elastic bumper.

[Action]

Since the main body and the mounting seat do not project outward from the outer diameter of the elastic bumper, the mounting seat does not come into contact with the door door and is not damaged.

The elastic bumper, the main body, and the mounting seat form a separate door stop, which can be rearranged according to the application.

For example, a main body having a latch is prepared, and the bolt shaft of the elastic bumper is inserted into the through hole of the main body.

When the floor surface is made of wood, the mounting seat may be screwed and fixed to the floor surface, and then a bolt shaft may be screwed into the mounting seat for assembly.

Also, if the floor surface is made of concrete, use a long bolt shaft, attach the mounting seat in advance, and then screw the bolt shaft protruding from the lower surface of the mounting seat to the anchor plug. Alternatively, it suffices to remove the mounting seat, project the bolt shaft below the main body, and screw it to the anchor plug on the floor.

Since the bolt head is embedded in the elastic bumper, it will not fall off during use.

〔Example〕

FIG. 1 shows an embodiment of a door stop according to the present invention, FIG. 1 is the same perspective view for explaining the use state, FIG. 2 is the same exploded perspective view,
FIG. 3 is a cross-sectional view showing a mounting state on a wooden floor surface, and FIG. 4 is an enlarged side view of a main part showing an engaging state with a latch receiving hook.

The door stop 1 includes an elastic bumper 2 formed by projecting a bolt shaft 5, a main body 3 for inserting the bolt shaft 5 into a through hole 6 to support the elastic bumper 2 on an upper portion, and a bolt shaft 5 screwed to the bolt shaft 5 at a lower portion of the main body. It is combined with the mounting seat 4.

More specifically, the elastic bumper 2 has a desired outer shape made of elastic rubber and has a bolt head 10 of the bolt shaft 5 embedded therein.

In this case, the bolt head 10 and the bolt shaft 5 having the optimum dimensions can be selected and used from among the standard commercially available bolts.

The bolt head 10 is integrally formed by inserting when the elastic bumper 2 is molded, and the bolt shaft 5 is projected from the center of the lower surface 11 of the elastic bumper 2. A protrusion 12 projects from the periphery of the bolt shaft 5. Reference numeral 13 in the drawing denotes a peripheral wall of the protrusion 12.

Next, the main body 3 can be formed into a cylindrical shape having a size shorter than the bolt shaft 5, and can be formed to have a smaller diameter than the outer diameter of the elastic bumper 2. A through hole 6 is provided in the main body 3 at the center in the axial direction, and a ring-shaped detent portion 14 projects from the upper end opening. The inner periphery of the rotation stopping portion 14 has a recess 15 and an inner peripheral wall 1 thereof.
And 6 are provided. Further, the outer periphery of the rotation stopping portion 14 is formed into a thin neck portion 17, and a latch 18 is provided in a hole 18 of the neck portion 17.
Both ends 20 of 9 are rotatably engaged. A buffer portion 21 having elasticity is wound around an intermediate portion of the latch 19. The buffer section 21 can be configured by winding a buffer tube. Reference numeral 22 in the drawing denotes a contact surface with the mounting seat 4.

Further, the maximum diameter of the mounting seat 4 is formed to be substantially the same as the outer diameter of the elastic bumper 2, a female screw hole 24 is provided at the center with the upper surface as a contact surface 23, and a countersink 25 ... It is formed.

By disposing the countersink 25 close to the periphery of the female screw hole 24, the outer diameter of the mounting seat 4 can be reduced.

In this case, the countersink 25 is arranged so as to be hidden by the lower surface contact surface 22 of the main body 3 when the main body 3 is placed on the mounting seat 4 by being moved inward from the outer periphery of the main body 3.

When mounting on the wooden floor 30 based on the above configuration,
Set the mounting seat 4 to a predetermined position on the wooden floor surface 30, and set the countersink 2
The set screw 26 is attached to the wooden floor surface 30 by screwing from 5. Next, when the bolt shaft 5 of the elastic bumper 2 is inserted into the through hole 6 of the main body 3, the protrusion 12 is inserted into the recess 15 and positioned in a state. In such a state, the bolt shaft 5 projects from the lower surface contact surface 22 of the main body 3.

Therefore, if the bolt shaft 5 is screwed into the female screw hole 24 of the mounting seat 4 and tightened, the bolt shaft 5 is assembled. In this case, the elastic bumper 2
In addition, the lower surface 11 is tightened around the entire circumference by the rotation preventing portion 14 of the main body 3, and the protrusion 12 and the peripheral wall 13 are recessed 15
Since the inner peripheral wall 16 and the inner peripheral wall 16 are fitted and in close contact with each other, they are assembled in a completely detented state and will not loosen due to the impact of the door.

In such an assembled state, the latch 19 is inserted into the receiving groove 33 of the latch receiving hook 32 fixed to the door 31 as shown in FIG.
Can be hung over.

On the other hand, when mounting on the concrete floor surface 34, as shown in FIG. 5, the elastic bumper 2 is inserted into the main body 3 and screwed to the mounting seat 4 in advance. In this case, the bolt shaft 5 is a combination of long things that protrude from the lower surface of the mounting seat 4.

Alternatively, the mounting seat 4 may be removed and the bolt shaft 5 may be projected from the lower surface of the main body 3.

In this state, it can be screwed and attached to the anchor plug 35 of the concrete floor surface 34.

The elastic bumper 2 and the main body 3 shown in the above embodiments
The mounting seat 4 is merely an example, and the design is not limited to the above shape, and various shapes can be changed.

[Effect of device]

As described above, in the door stop of the present invention, the main body and the mounting seat are separated from each other, and a countersink for receiving a set screw necessary for mounting on a wooden floor is formed around the female screw hole of the mounting seat. Since it is arranged inside the outer circumference, the outer diameter of the mounting seat can be made small.

In this way, by making the maximum diameter of the outer peripheral part of the main body and the mounting seat approximately the same as the outer diameter of the elastic bumper, even when the lower end of the door is close to the floor, parts other than the elastic bumper such as the mounting seat Can prevent damage to the door without contacting the door.

In addition, since the bolt shaft also serves as an anchor bolt when it is mounted on a concrete floor surface, it is not necessary to separately prepare the anchor bolt, and the mounting is easy.

Moreover, since the bolt head is embedded in the elastic bumper, the elastic bumper does not fall off from the bolt head during use due to the impact of the door.

Further, as the bolt shaft, commercially available standard products of various lengths can be used as they are, so that the manufacturing process of the door stop can be simplified and the manufacturing cost can be reduced.

Further, since the door stop is divided from the elastic bumper, the main body and the mounting seat, it is possible to meet various uses by exchanging each part.
