Description

[Detailed Description of the Invention] The present invention relates to a door stop device used for doors of fittings, furniture, etc.

It is already known that magnets are used as this type of door stop device, and the door stop device that uses magnets has a contact between the door stop body fixed to the floor etc. and the receiver fixed to the door. It is known that the contact surfaces are formed into arcuate surfaces that match each other to prevent misalignment and strengthen against impact. However, this conventional device is only effective for magnetic types, and cannot be applied if the door is already equipped with a stop device.
It was impossible to use it as a general doorstop device.

Therefore, the present invention was made with attention to this point, and the purpose is to provide a doorstop device that can be easily applied not only when using magnets but also as a general doorstop. In a doorstop device formed of a magnetic force absorbing material and consisting of a doorstop main body and a receiver having arcuate surfaces that match and contact each other, there is a permanent magnet on the arcuate surface of the doorstop main body. The door stop device is characterized in that it is provided with a magnet auxiliary plate, and that the receiver is removably provided with an abutting member on a fixed body via a cushioning material.

Next, an example of implementation of the present invention will be described with reference to the drawings. In the figure, reference numeral 1 denotes a door stop main body. This door stop main body 1 has a substantially cylindrical shape with an annular flange at the lower end, and is fixed to a floor etc. by passing screws 2 through the annular flange, and the annular flange is attached to a cover 3. It is covered with a twist. Further, the top surface of the door stop main body 1 has a spherical shape with a center point shifted from the central axis, and a bulge 4 is partially formed on the top surface. A permanent magnet 5 is provided over the portion 4, and magnet auxiliary plates 6, 6a are provided on both edges of the permanent magnet 5 to enhance the attraction force.

On the other hand, numeral 7 in the figure is a receiver that is attached to the door, and this receiver 7 is a fixed body 9 having an annular flange portion 8.
This annular flange portion 8 has a screw 10.
The annular flange portion 8 is covered with a cover 12 having a through hole 11 in the center.

The door stop main body 1 is inserted into the through hole 11 of the cover 12 through a buffer rubber 13 having a through hole in the center.
A concave surface 14 having approximately the same curvature as the top surface of the fixed body is formed, and a contact body 15 having a hole in the center that communicates with the through hole of the buffer rubber 13 is inserted through the hole with a screw 16, and the fixed body It is removably fitted into a hole provided at 9, and 17 is a push nut for receiving the screw 16.

Since the abutting body 15 and the buffer rubber 13 are screwed together via screws 16, the cushioning material 13 can be removed as necessary when installing the abutting body 15 to the door.
only can be attached to the fixed body 9. Further, even after the door stop device is once attached to the door, it is possible to replace only the abutting body 15 or the abutting body 15 and the cushioning rubber 13. In this case, the fixed body 9 can be removed from the door by first removing the cover 12 and turning the screw 10. Next, by turning the screw 16 and removing it from the push-nut 17, the contact body 15 (and the buffer rubber 1
3) can be removed from the fixed body 9. Then, in order to reinstall it, first, only the contact body 15,
Alternatively, the abutting body 15 and the buffer rubber 13 are screwed together with the fixed body 9, and a push nut 17 is attached from the back side, and the screw 16 is used to prevent it from coming off. push nut 1
7 has a hole having approximately the same diameter as the screw 16, and is press-fitted into the screw 16 so that the hole 7 is inserted into the screw 16 and is prevented from coming off. Next, after attaching the fixed body 9 to the door with screws 10, the cover 12 is attached.

Note that the cushioning rubber 13 is packed in the contact body 15 almost densely, but the bottom surface of the cushion rubber 13 is filled with the contact body 15
It is curved to the side, and a gap is formed with the surface of the fixed body 9, so that it can be pressed and expanded toward the fixed body 9 when it comes into contact with the door stop main body 1.

According to the door stop device according to the present invention configured as described above, since the abutting body is freely removable, suction force is no longer required, such as when the door is equipped with a door closer with a stop device. Even in this case, it can be used as a general doorstop device with only the cushioning material, and there is no need to separately prepare multiple types of products. In addition, the cushioning rubber is curved, so that the screws that attach the abutting body and the cushioning rubber can slide in the axial direction.When the fixed body comes into contact, the elasticity of the cushioning rubber itself, the expansion of the cushioning rubber, and the sliding of the mounting screw are combined. This provides an excellent cushioning effect.

Claims (1)

[Scope of utility model registration request] In a doorstop device consisting of a doorstop body and a doorstop receiver that have arcuate surfaces that match and abut each other, the doorstop receiver is attached to a fixed body that is fixed to a door, etc., and a buffer that curves toward the contact body and the doorstop body. The material is removably attached to the material, and a gap is provided between the fixed body and the cushioning material.
Furthermore, the abutting body and the cushioning material are attached to the fixed body by a locking member that is slidably supported in the axial direction by a push nut, and when the curved cushioning material comes into contact with the door stop body, it is pressed and expanded toward the fixed body. A door stop device characterized in that it is configured such that the contact body can be removed and used as necessary.
