DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door stop which is fixed to an inner surface of an opening frame.

[0002]

2. Description of the Related Art A door stop 11 is provided on an opening frame member 15 such as a door frame to regulate a closing position of the door when the door is closed. Generally, the door stop 11 has a substantially U-shaped door stop main body 12 as shown in FIGS.
A fitting piece 13z, 13z which is continuous with the fitting part 13z is formed of a facing fitting part 13, and a packing 14 which is in contact with a door is fixed to a side surface of the main body part 12.

The door stop 11 is fitted with a door stop 11 having a fitting portion 13 having a resilient force in the width direction into a fitting groove 16 provided on the inner surface of the opening frame member 15 in three longitudinal directions.
The fitting side face 13A of the door stop 11 is pressed and pressed against the side of the fitting groove 16 of the opening frame member 15, and is held and fixed to the opening frame member 15. The door stop 11 fixed to the opening frame member 15 in this manner abuts on the door via the packing 14 to reduce noise and impact generated at the time of closing, and regulates the closing position of the door.

Next, the door stop 11 to the opening frame material 15 is actually
Looking at the mounting method, the fitting groove bottom surface 1 of the opening frame material 15
After applying the adhesive on 6B, fit the door stop 11
The frictional force obtained by the fitting side surface portion 13A of the door stop 11 pressing the fitting groove side surface 16A of the opening frame member 15, and the bonding obtained by directly bonding the fitting groove bottom surface 16B and the fitting bottom surface portion 13B. Although it was attempted to improve the mutual adhesion force by the force, when the fitting portion 13 was fitted into the fitting groove 16, the fitting portion 13 side was deformed inward, so that as shown in FIG. Since the bottom surface portion 13B floats from the bottom surface 16B of the fitting groove and the gap X is formed and the adhesive does not function well, the door stop 11 comes off from the opening frame material 15.

[0005]

In order to solve the above-mentioned problems, the present inventor has proposed a door stop main body 2 having a packing 4 and installed on the inner surface of an opening frame member 5 and exposed to the outside. A door stop having a fitting portion 3 to be fitted into the fitting groove 6 of the frame member 5 has a substantially gate-shaped cross-sectional shape, and a soft packing 4 is provided on one side thereof with one end fixed thereto. The main body 2 and a fitting side surface 3A which is bent in an L shape inward from both side ends of the door stop main body 2 and has a plurality of protrusions 7A on the outer surface, and the tip thereof is further bent inward to go to the center. Bottom part 3 inclined downward according to
B, the fitting pieces 3z, 3z formed with the joint 3C bent upward from the tip of the fitting bottom surface 3B are provided so that they face each other and the joints 3C contact in parallel. Invented is a door stop 1 including a fitting portion 3 formed.

[0006]

The present invention is characterized in that the fitting bottom portion 3B of one door is tapered downward so that the fitting groove 6 of the opening frame is formed.
When the door stop 1 is fitted into the door frame 1, the fitting bottom portion 3B of the door stop 1 is brought into close contact with the fitting groove bottom surface 6B of the opening frame member 5 so that the bonding function can be sufficiently exhibited. Also, a projection 7B is formed on the fitting bottom surface 3B to increase the bonding surface with the fitting groove bottom surface 6B.

Hereinafter, description will be made with reference to the drawings. FIG. 1 is a cross-sectional view of one embodiment of a door stop 1 according to the present invention. 3z, 3
z, that is, the fitting portion 3. An elastic packing 4 having one end fixed to the side surface of the door stop main body 2 and the other end not fixed is provided at a portion of the side surface of the door stop main body 2 where the door comes into contact.

The door stop body 2 and the fitting portion 3 are made of synthetic resin, metal or the like, and are manufactured by extrusion molding and bending. A decorative material such as a decorative paper or a decorative synthetic resin sheet may be adhered to the entire front surface of the door stop main body 2 in accordance with the color of the door or the door frame, and the cosmetic may be arbitrarily applied. The door stop main body 2 may be formed to have a substantially gate-shaped cross section, and the corners of the outer surface may be curved.

Reference numeral 4 denotes a packing made of a soft synthetic resin having elasticity, synthetic rubber, metal, or the like, one end of which is fixed to an upper portion of the side surface of the door stop main body 2, and the other end of which is a door stop main body 2. The lower part of the side is spaced apart. The packing 4 has a function of abutting on a closed door to reduce the impact force and noise generated when the door is closed.

The fitting portion 3 is a so-called foot portion, and has a substantially L-shaped fitting side portion 3A continuous from the door stop main body 2 having a substantially gate-shaped cross section. The joining portion 3C of the fitting piece 3z, which is formed by a fitting bottom portion 3B that is bent to bend and a substantially O-shaped joining portion 3C that is bent upward from the tip of the fitting bottom portion 3B, is parallel to each other. The fitting portion 3 is fitted into a fitting groove 6 provided on the inner surface of the opening frame member 5 so as to be in contact with each other, and one door stop is fixed. The fitting portion 3 has elasticity in the width direction, and presses the fitting side surface 3A against the side of the fitting groove 6 of the opening frame member 5 to hold and fix the door stop 1 to the opening frame member 5.

A plurality of projections 7A extending in the longitudinal direction are provided on both fitting side surfaces 3A. The projection 7A resiliently contacts the side face 6A of the fitting groove, and also opposes a force that tends to come off by a frictional force caused by attaching the projection 7A.

The fitting bottom 3B is tapered downward from the side to the center. Further, a plurality of projections 7B are formed on the fitting bottom surface 3B, and the projections 7B on the bottom surface are also continuous in the longitudinal direction like the projections 7A on the side surfaces.

As described above, the fitting bottom portion 3B is formed in a tapered shape inclined downward, as shown in FIG.
When the fitting portion 3 is fitted into the fitting groove 6, the fitting portion 3 is deformed inward, and the fitting bottom portion 3B is lifted up to be level with and close to the fitting groove bottom surface 6B to form a gap X. Instead, the adhesive applied to the fitting groove bottom surface 6B functions. In addition, the protrusions 7B provided on the fitting bottom surface 3B increase the bonding area so that bonding can be performed effectively.

The joint 3C is opposed to the joint 3C of the other fitting piece 3z so as to be in parallel contact with the joint 3C. The thickness of the joint 3C is set to be smaller than that of the other parts, and when the fitting 3 is deformed during fitting. In addition, a deformation is regulated by contacting the other joint 3C. Although the embodiment shown in the drawings has been described above, the shapes of the door stop main body and the packing are not limited to the embodiment, and it goes without saying that the shape can be changed at any time.

[0015]

[Effect] When the door stop 1 is set in the opening frame, an adhesive is applied to the bottom of the fitting groove 6 provided on the inner surface of the opening frame member 5 and the door stop 1 is fitted, and the fitting bottom portion 3B is tapered. And the fitting portion 3 is deformed inward, so that the fitting bottom portion 3B is horizontal with the bottom surface of the fitting groove 6 and is in close contact with the bottom surface of the fitting groove 6 and one fitting bottom portion 3B. Since there is no gap between them, the function of the adhesive can be sufficiently exhibited.

Further, since the projection 7B is formed on the bottom surface portion 3B of one fitting base per door, the bonding area at the bottom surface portion 3B can be increased, and more reliable bonding can be performed. Adhesion with 3 is improved, and it is possible to prevent the door stop 1 from coming off from the opening frame member 5 and falling off.
