Description

[Detailed Description of the Invention] The present invention relates to a door device, in which a mounting leg 9 is protruded from the back side of an elastic plate-like body 7, and a wooden scrap 3 having a substantially T-shaped horizontal cross section is provided.
A door 2 is formed with a curved surface 13 on the back side of the wood scraps 3, and is installed in the door frame 1 so as to be horizontally rotatable.
A fitting groove 10 is provided on the movable side end surface of the fitting groove 10.
The wood scraps 3 are attached to the side end surface of the door 2 by fitting the mounting legs 9 of the wood scraps 3 into the door frame 1 of the wood scraps 3.
This relates to a door device in which the end of the door stop 4 attached to the inner surface is made to protrude outward from the end surface of the door 2.

An object of the present invention is to provide a door device that can improve airtightness by bringing the door frame and wood scraps into close contact when the door is closed.

The present invention will be explained in detail below using examples.

The door 2 is mounted on a hinge 6 so as to be horizontally rotatable within the door frame 1, and a door stop 4 is mounted vertically on the inner surface of the door frame 1 on the movable side (handle 5 side) of the door 2.

Reference numeral 3 is a wood scrap made of an elastic material such as rubber, and has a T-shaped horizontal cross section with a mounting leg 9 having a fitting protrusion 8 protruding from the back side of a plate-like main body 7.

The wood scraps 3 are attached to the entire vertical length of the door 2 as shown in FIG. 3 by fitting the mounting legs 9 into the fitting grooves 10 provided on the movable side end surface of the door 2.

At this time, the end of the wood scraps 3 on the door stop 4 side is made to protrude from the side end surface of the door 2 over the entire vertical length to form a protrusion 11.

A tapered surface 1 is formed on the front side of the wood scraps 3 so that the wall thickness a on the protrusion 11 side is smaller than the wall thickness on the opposite side as shown in FIG.
2 is in shape, and there is also a curved surface 1 on the back side of the wood scraps 3.
3 is a formality.

Therefore, in the door device as described above, when the door 2 is closed, the protrusion 1 of the wood scraps 3 is removed as shown from a to b in Fig. 4.
1 protrudes from the door stop 4, and the protruding part 11 is pressed by the door stop 4, causing the wood scraps 3 to deform as shown in FIG. This makes elastic contact with the door 2, and airtightness is achieved when the door 2 is closed.

Here, since the protruding portion 11 of the wood scraps 3 is made thin and has a curved surface 13 on the inner surface of the wood scraps 3, the wood scraps 3 protrude outward due to the pressure from the door stop 4. This tends to cause bending deformation.

In addition, the wood scraps 3 may be provided not only at the movable side end of the door 2 but also on the end face of the pivot side end.If the wood scraps 3 are provided on both sides of the door 2 in this way, the door 2 can be closed. This further improves the airtightness of the opening.

Also, if the left and right width of the door 2 is larger than the inner width of the door frame 1, adjust the width of the door 2 during installation by cutting the end face of the door 2 as shown in Figure 3 a to b. Even if the end face of the door 2 is cut in this way, the cut surface can be covered up by attaching the wood scraps 3.

As described above, the present invention forms wood scraps with a substantially T-shaped horizontal cross section by protruding mounting legs from the back side of an elastic plate-like main body, and also forms a curved surface on the back side of the wood scraps. This wood scrap was attached to the side edge of the door, and the end of the wood scrap on the door stop side attached to the inner surface of the door frame was made to protrude outward from the side edge of the door, so when the door was closed, The protrusion that protrudes from the side end face of the door toward the door stop hits the door stop, and the wood scraps are elastically deformed on the curved surface of the back side so that they protrude toward the front side, and as a result, the wood scraps become attached to the door. By making elastic contact with the inner surface of the frame from a direction perpendicular to that surface, it is possible to improve the airtightness of the door when the door is closed without causing the wood scraps to rub against the inner surface of the door frame. The scraps are restored and do not come into contact with the inner surface of the door frame, so there is no problem in opening and closing the door.

Additionally, the shock of closing the door can be cushioned with wood scraps.

Claims (1)

[Scope of utility model registration request] Mounting legs protrude from the back side of the elastic plate-like body to form wood scraps with a horizontal cross section that is approximately T-shaped, and a curved surface is formed on the back side of the wood scraps, allowing for horizontal rotation within the door frame. A fitting groove is provided on the side end surface of the movable side of the door attached to the door, and the mounting leg of the wood scraps is fitted into this fitting groove to attach the wood scraps to the side edge surface of the door. A door device in which the end of the door stop attached to the inner surface of the door frame projects outward from the side end surface of the door.
