Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a door stop for a floor.

[Conventional technology]

When opening the door, there is a door stop that restricts further opening of the door at the maximum allowable opening position of the door to prevent the door from being opened more than necessary and the part of the door or the knob from colliding with the pillar or wall. It is fixed on the floor.

[Problems to be Solved by the Invention] A conventional door stop is fixed at a predetermined position on the floor with at least two screws. For this reason, it takes a lot of time to fix the screw, and the head of the screw is exposed on the outer surface of the door stop, impairing the external appearance design, and the screw may loosen due to long-term use and the door stop may become loose.

The present invention can be fixed with one dish screw, and the design is improved by not exposing the head of the dish screw.
It is an object to provide a door stop that can prevent loosening of dish screws.

[Means for Solving the Problems]

In order to achieve the above object, the door stop of the present invention includes a door stop body in which a mounting piece having a screw hole is integrally formed on one side and a pin is provided on a bottom surface, and a portion of the screw hole. The gist of the present invention is that it comprises a cushioning body that covers the entire top surface of the mounting piece and is fitted into the door stop body.

[Action]

In the door stop of the present invention, the pin protruding from the bottom of the door stop body is fitted into the hole drilled in the floor, and fixed with one dish screw, and then the head of the dish screw is covered. Since the shock absorber is fitted to the door stop main body, it can be firmly fixed with one dish screw without exposing the head of the dish screw, improving workability and design at the site, and the shock absorber As a result, the movement of the head of the dish screw is restricted so that the dish screw does not loosen even if it is used for many years.

〔Example〕

Hereinafter, the door stop of the present invention will be described based on the illustrated embodiment.

In the figure, reference numeral 1 is a main body for a door, which is formed by using a desired metal or synthetic resin such as aluminum alloy, copper, brass, stainless steel, etc., and if necessary, subjecting the outer surface to a surface treatment such as plating. As shown in the drawing, the door-contact main body 1 has an oval or elliptical cross-section, and the top surfaces at both ends are rounded, and the outer surface thereof has no corners. , This size is suitable as a door stop when screwed to the floor, for example, height 30mm
The size is appropriately set within a range of up to 80 mm, a width of 15 mm to 35 mm, and a length of 20 mm to 60 mm, but is not limited to this size.

Further, one side surface of the door-contact main body 1 is cut out in a substantially vertical direction except for a mounting piece 2 integrally formed in a lower portion of the door-contact main body 1, and a recess 3 is formed in a central portion while leaving an outer periphery of the vertical surface. A screw hole 4 is formed on the top surface of the mounting piece 2 which is formed and is bent at a substantially right angle to the vertical surface and is continuously provided.

Further, pins 5 are planted on the bottom surface of the door-stop body 1 with the screw holes 4 at a required interval. The pin 5 is fitted and fixed to the bottom of the main body 1 to a certain length so that the pin 5 protrudes from the bottom surface 6 of the main body by a length necessary for door stop fixing, and the tip of the pin 5 is sharpened if necessary. First. Reference numeral 7 in the figure is a cavity formed in the door-stop body 1 by opening from the bottom surface thereof, and is provided to reduce the weight of the door-stop body without impairing its strength.

Reference numeral 8 denotes a cushioning body having a required elastic coefficient, which is made of rubber, synthetic resin or the like, and the shape and size of the cushioning body 8 correspond to the shape of the cutout portion of the main body 1 of the door stop. When the 8 is fitted, the buffer body 8 comes into contact with the screw hole 4 of the main body 1.
In addition to covering the entire upper surface of the mounting piece 2 including the portion, the door contact is formed by the door contact main body 1 and the cushioning member 8 so that the outer surface thereof has no irregularities or corners. In addition, a fitting protrusion 9 that is fitted in the recess 3 of the door stop body 1 is integrally formed on one side surface of the buffer body 8, and the double-sided adhesive tape 10 is attached to the fitting protrusion. At the time of fitting to the door stop main body, an adhesive is applied to bond the inner surface of the recess 3 and the fitting projection 9 to each other.

Reference numeral 11 in the drawing denotes a countersunk screw, which is inserted into the screw hole 4 of the mounting piece 2 to fix the door-contact main body 1 to the floor surface.

In the door stop constructed as described above, first, a hole for fitting the pin 5 is punched at a predetermined position where the door stop is installed on the floor surface, and the pin 5 is fitted into this hole. As a result, the door stop is roughly positioned, and then the direction of the door stop is adjusted, that is, the shock absorber 8 is located on the door side to be opened, and then the screw hole 4 is inserted.
Screw the plate screw 11 into the. At this time, the head of the countersunk screw 11 is fitted into the screw hole 4 and does not project to the top surface of the mounting piece 2.

Next, the double-sided adhesive tape 10 is adhered to the fitting protrusion 9 of the buffer body 8, but after applying an adhesive, the fitting protrusion 9 is fitted and adhered in the recess 3 to be integrated. As a result, the head of the countersunk screw 11 is covered with this cushioning body 8, its movement is restricted, and the notch portion of the door-contact main body 1 is also filled with this cushioning body 8.

[Effect of device]

According to the present invention, the door stopper can be firmly fixed with one dish screw without exposing the head of the dish screw, and the workability and design on the site are improved, and the head of the dish screw is buffered. The movement is restricted and the plate screw does not loosen even after long-term use.
