Abstract

PURPOSE:To attain easy installation of a door stopper without allowing loosening of the stopper body, by integrally forming a hollow cylindrical member containing a retainer that holds a compressible spring to a fitting protrusion, and a skirt member fitting over the outer periphery of a fitting pedestal, and by installing a buffer member on the upper part of the stopper body. CONSTITUTION:A fitting pedestal 1 is provided with a fitting protrusion 6 at its center and plinths 7 that are stretching out to both sides of the fitting protrusion 6. Through holes 8 for wood screw fitting are bored on the plinths 7. A column-shaped retainer 2 to hold a compressible spring 4 is jointed at its end with a spindle to the fitting protrusion 6. A skirt member 12 that fits over the outer periphery of the fitting pedestal 1, and a hollow cylindrical member 13 that contains the retainer 2 are integrally formed, and a flange member 14 is provided inside to form a seat to accept the compressible spring 4. A groove is formed at the upper end of the fitting protrusion 6, and the bottom end of the retainer 2 is turnably connected with a pin 11 to the groove. At installing a door stopper, the hollow cylindrical member is detached from the fitting pedestal 1 against the force of the spring 4 and turned sideways around the pin 11, and wood screws 16 are screwed in the through holes 8.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to doorstops. More specifically, the invention relates to a doorstop for holding a door in a pressed state when the door is opened in a building or vehicle. The present invention also relates to a door stop that is easy to install.

[Conventional technology]

A conventional door stop will be explained based on FIGS. 4 and 5.

The door stop (50) shown in FIG. 4 is of a type that is installed horizontally on a vertical wall (W), and has a relatively elongated main body (51). The main body (51) is a hollow cylindrical body, and a female thread (53) is cut on the inner periphery of the base end thereof.

A screw (55) is screwed into the vertical wall (W) into the female threaded portion (53) through a through hole of the male threaded body (54). A rubber shock absorber (5) is attached to the tip of the main body (51).
2) is fixed, and its buffer body (52) is marked with an arrow (
D) A door moving from the direction can be collided with.

The door stop (60) shown in FIG. 5 is of a type that can be mounted upright on the floor (F), and has a relatively thick and short main body (81). The basic configuration is the door stop (5
Same as 0), female thread part (63), male thread body (64),
It is equipped with screws (85). A large-diameter buffer (B2) is fixed to the top of the main body (61), and the buffer (6
The door moving from the direction of arrow (D) will collide with the side of 2).

[Problem to be solved by the invention]

In the conventional door stop (50), (B0), the main body (51), (
61) and the male threaded bodies (54), (64) are screwed together, so there is a problem that they loosen little by little each time the door collides. Therefore, if the door is used for a long period of time, the main bodies (51) and (81) may come off and damage the door.

The present invention has been made in view of the ridged situation, and an object of the present invention is to provide a door stop whose main body does not become loose.

A further object of the present invention is to provide a door stop that can be easily installed.

[Means to solve the problem]

The door stop of the invention has a fitting protrusion on the mount (a mounting base with a fitting protrusion in the center and a screw insertion hole drilled in the sides protruding on both sides of the fitting protrusion). A column-shaped retainer for holding a compression spring with one end pivoted (
c) A skirt part that fits around the outer periphery of the mounting base and a hollow cylinder part that can accommodate the retainer are continuously formed,
A main body is provided with a flange portion which receives a compression spring and abuts the top surface of the fitting protrusion inside the skirt portion and the hollow cylindrical portion in a continuous position. It consists of a spring, (e) a buffer fixed to the upper end of the main body.

[For production]

In the present invention, the main body and the mounting base are not screwed together, but are fitted together, and are further crimped by a compression spring, so that they will not come loose due to a collision with the door.

Further, in the present invention, since one end of the retainer is rotatably attached to the mounting base, the main body can be tilted with respect to the mounting base. When the main body is tilted, there is more space above the mounting base, making it easier to insert and screw in screws into the screw insertion holes.

[Example] Next, the present invention will be explained in detail.

Fig. 1 is a sectional view of the main parts of a door stop according to an embodiment of the present invention, Fig. 2 is a side view of the mounting base shown in Fig. 1, and Fig. 3 is an explanatory diagram showing the door stop installation work. be.

The door stop shown in Figures 1 and 2 includes a mounting base (1), a retainer (2), a main body (3), a compression spring (4), and a shock absorber (
5).

The mounting base (1) has a fitting protrusion (6) that protrudes high in the center and a base (7'J) below it, and the base (7) has screw insertion holes (8) from 3 to There are 4 holes perforated.
7) is formed with a screw hole in the center for screwing the anchor bolt from below. A groove (9) is formed at the upper end of the fitting protrusion (6), and the retainer (2's base end is rotatably supported by pin a1) within this groove (9).

The retainer (2) is a rod-shaped member with a spring seat formed at its upper end.

The main body (3) consists of a skirt part (12) and a hollow cylinder part. The skirt portion 02) has a shape that tightly fits around the outer periphery of the mounting base (1). The hollow cylinder part (12) is a cylinder having an internal cavity that accommodates the retainer (2), and the hollow cylinder part and the skirt part side are formed continuously.The skirt part (12) and the hollow cylinder part (2) are formed continuously. A flange portion 04) is formed inside the continuous portion. This flange part ■ functions as a spring seat to receive the compression spring (4), and when the skirt part 02) is fitted to the mounting base (1), the fitting protrusion (
6) comes into contact with the top surface of. A buffer body (5) is fixed to the upper end of the hollow cylindrical portion (2) to absorb the impact of the door.

The compression spring (4) is interposed between the spring seat of the retainer (2) and the flange (3) of the main body (3).

When installing the door stop of the present invention on the floor or wall, as shown in Fig. 3, pull the main body (3) away from the mounting base (1) against the elastic force of the spring (4) and press the pin 01). It is best to roll it over with the center at the center. In this way, the mounting base (1
) Since the upper space becomes wider, insert a screw O into the insertion hole (8).
Inserting Q makes it easier to screw in with a screwdriver surface, etc.

In the present invention, when the door collides with the shock absorber (5) during use, the impact is transmitted from the main body (3) to the mounting base (1), but the connection between the main body (3) and the mounting base (1) is through screws. Since it is not a stopper, the main body (3) will not loosen and come off. Further, since the main body (3) and the mounting base (1) are tightly fitted and pressed together by the spring (4), there is no possibility of shaft wobbling in the main body (3).

Further, in the present invention, since the mounting interval between the screws OQ on the mounting base (1) can be widened, the mounting strength is high and it is easy to withstand the impact of the door.

〔Effect of the invention〕

In the present invention, the screws on the main body do not loosen and come off during use, so it can be used safely for a long period of time, and the door will not be damaged. Also, the installation work of the door stop is easy.
