Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door structure for preventing an impact sound when a door is closed.

[0002]

2. Description of the Related Art When a door is opened and closed, particularly when a hinged door is closed, a loud impact sound is generated when the door is closed vigorously. Various measures are currently being devised to prevent this. For example, a so-called shock absorber using a fluid (oil) (hereinafter referred to as a door check)
And the use of elastic pads such as rubber. The former uses a flow resistance of a viscous fluid (oil) to cushion the impact, and exhibits a certain effect. However, it is not only expensive in price but also has inherent problems. The latter is widely used because it is inexpensive and easy to handle. However, the buffer effect cannot be said to be sufficient due to dimensional restrictions.

[0003]

The door check has a relatively large shape due to its structure, is expensive, and has to be complicated in that the flow clearance of the viscous fluid must be adjusted according to the difference in temperature. There is. That is, if this adjustment is not appropriate, if it is too weak, it will not be possible to absorb the impact, and if it is too strong, resistance will be caused to close the door, and the door closing speed will be extremely slow. Also, since viscous fluid (oil) is used for the device,
In particular, when used as a door in a room, there is a problem that the surroundings may be contaminated by leakage or the like. In addition, although the latter is advantageous in that it is inexpensive and easy to handle and is used relatively frequently, there is a dislike that sufficient buffering is not performed due to the mounting space problem.

The noise generated when the door is closed is substantially caused by an impact contact between a door and a surface of a door stop member at a stop which is used to determine a closing position of a door provided on a pillar or a gate. . Therefore, noise cannot be eliminated as long as the door stops. Further, the door stop is provided for fitting the catch of the locking portion provided on the handle knob for locking the door to the closed position with the female fitting hole. Therefore, as long as the door is locked in this manner, the door stop cannot be eliminated and the noise cannot be eliminated. In many homes, there are many cases in which no noise damping device is provided, and it is not an exaggeration to say that the doors are completely unprotected on a daily basis. The present invention proposes, in order to improve the above situation, a door structure which is inexpensive and which can be easily handled by an amateur and which avoids noise.

[0005]

SUMMARY OF THE INVENTION According to the present invention, there is provided a locking member position of a shock absorber having at least one spring shock absorbing member provided in contact with a door to be closed relative to a door to be closed and provided in a turning radial direction of the door. A lock member made of a permanent magnet or iron piece provided at a position facing the permanent magnet or iron piece provided on the door, the locking lock portion is omitted from the door handle, and a pillar or upper crosspiece is provided. The present invention solves the problem by a door structure in which a door stop member for abutting a door to be provided in (1) is omitted, and the position of the locking member is a tip portion of a spring buffer member and / or a spring buffer. The door structure is characterized by being on the main body member surface adjacent to the member position.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Japanese Patent Application No. Hei 8-
No. 118130 "Door shock absorber" is an example of a door shock absorber invented for this purpose, and although it is correspondingly adapted for damping the door closing energy, as described above, Such a shock absorber alone does not solve the fundamental problem of door noise.

Therefore, it is necessary to have a door structure which eliminates a door stop which is a cause of noise, and for this purpose, a door structure provided with a substitute for the function given to the door stop is required. is necessary. The function given to the door stop is, as described above, the relative position between the lock of the locking lock portion provided on the handle knob for locking the door in the closed position and the female fitting hole provided on the pillar. Exists to make a realistic fit. The setting of the position at the time of closing is provided in a door shock absorber for buffering energy at the time of closing. Of course, the door shock absorber is fixed at a predetermined position on a pillar or upper cross bar.

That is, the setting and fixing of the position of the door when the door is closed can be performed by the distal end portion of the spring buffer member of the door buffer device or /
And a magnet or iron piece provided at the position of the locking member on the body member surface adjacent to the position of the spring buffer member. The iron piece or the magnet piece is fixed to the surface of the door facing the magnet piece or the iron piece. Of course, if the relative position of the door itself is made of a magnetic material, the piece provided in the door shock absorber will be a magnet piece.

The force of the magnet piece necessary for fixing the door is about 300 to 2000 gauss in terms of the number of magnetic fluxes, and the urging force of the spring of the door shock absorber is about 0.05 to 0.1 kg / mm.
The amount of deflection of the spring is preferably about 5 to 20 mm. If the locking member is located at the tip of the spring cushioning member of the door cushioning device, the closing position of the door is returned to the initial position of the spring, so that the force of the magnet piece is as small as possible.
It is preferable to be about 0 Gauss, and it is preferable that the amount of deflection of the spring is as small as about 5 to 10 mm.

However, when the position of the locking member is on the surface of the main body member adjacent to the position of the spring buffer member of the door buffer, the closing position of the door is biased by the spring and the force of the magnet piece is biased by the spring. It is necessary to be larger, and it is preferable to be about 1.1 to 1.3 times the urging force F of the spring. In this case, the amount of deflection of the spring can be large, and is 10 to 20 m.
m is preferable. Further, it is desirable to provide a slight buffer portion between the magnet piece and the main body member by air or a spring.

The shock absorber for the door is screwed or glued to the post or the upper cross bar relative to the door. Also, by omitting the door stop, there is a gap between the door and the pillar, and the upper rung (Mume),
If sound leakage or gap-like wind is a problem, an elastic seal member may be provided to close between the door and the pillar or the upper crossbar (meat). The details will be described below with reference to the drawings.

FIG. 1 is a schematic view showing a door structure according to the present invention. FIG. 4 is a schematic view showing a conventional typical door structure.
FIG. 1 is an external view of one embodiment of a spring damper which is a component of the present invention, and FIG. 3 is an exploded explanatory view showing one embodiment of the spring damper. The drawings show one embodiment, and the structure, dimensions, and the like are not limited thereto as long as they are in accordance with the gist of the present invention.

1 and 4, reference numeral 1 denotes a door, 2
Is a pillar or vertical frame, 3 is an upper cross bar (commonly called a mud), 4 is a door stop, 5 is a handle, 51 is a handle knob, 52 is a locking lock, and 53 is a female fitting corresponding to the locking lock. 2 and 3, reference numeral 10 denotes a spring damper, 11 denotes a shock absorber main body, 12 denotes a piston, 13 denotes a magnet piece or iron piece attached to the tip of the piston, and 14 denotes a magnet piece or iron piece attached to the shock absorber main body. , 15
Denotes a buffer spring 1, and 16 denotes a buffer spring 2.

As is apparent from FIG. 1, the door structure according to the present invention has a door stop of 4 in the conventional door structure.
The locking lock portion 52 of the door handle and the female metal fitting 53 corresponding to the locking lock portion are omitted. Instead, the door side magnet piece or iron piece 30 provided at a position relative to the spring shock absorber 10 and the door spring shock absorber.
Is fixed.

The total urging force of at least one or a plurality of springs of the spring shock absorber 10 is such that the spring coefficient k is 0.05 to
0.10 kg / mm, and the spring deflection h is given by about 5 to 20 mm. The closing energy of the door is preferably absorbed parabolically over the stroke. The door 1 is closed by a magnetic force between the magnet piece and the iron piece between the door 1 and the spring buffer. The magnetic force is given by a permanent magnet that generates a magnetic flux of about 500 to 1000 Gauss. The permanent magnet is used as the magnet piece 30 on the door side, and the polarity is switched to the magnet piece on the spring damper 10 side. By switching, it is also possible to operate to automatically open the door that is closed due to the repulsion of the polarity. This switching signal can be performed by a remote operation signal such as an ultrasonic wave.

Since the door 1 is closed by the magnet piece, the lock portion 52 provided on the handle portion of the conventional door and the female metal fitting 53 corresponding to the lock portion can be omitted. The handle can be replaced with a simple handle, such as an artistic handle or a simple dent.
Further, the door stop can be eliminated by this omission, so that the price of the door structure is reduced.

As described above, the omission of the door stop causes a gap between the door and the pillar or the upper cross bar, so that sound leakage from the gap or a gap-like wind may cause a problem. An elastic seal member 7 may be provided at the end of the door so as to cover between the column and the upper cross bar. The elastic seal member 7 can be formed of a sheet such as rubber or vinyl chloride, or a spacer made of cork or sponge material.

[0018]

As described above, the present invention is a door structure for preventing noise when the door is closed, and is less expensive than a conventional door structure. Although the present invention has been described with reference to a Western hinge type door, the present invention can also be applied to a Japanese style slide type door, bran, shoji, and the like.
