Abstract

PURPOSE: To reduce labor, noises and an impulse at the time of opening and closing by installing a sprocket and a torsion coil spring to a shaft opening and closing a shutter door and working repulsive power while being resisted to its own weight of a shutter. CONSTITUTION: A shutter 5 slidably mounted along guide grooves extending over the rear plate side through a ceiling from an opening section without being wound is opened and closed by balancing weight by a shaft 18. That is, when the shutter 5 is stopped at an intermediate place, hanging length on the opening section side of the shutter 5 and hanging length on the rear plate side approximately coincide, and weight on both hanging sides is balanced, and the shutter is stopped. When the shutter 5 is opened, the repulsive power of a torsion coil sring 20 is maximized upwards at the place of closing, and the shutter 5 can be opened only by applying small force to the shutter 5. When the shutter 5 is closed, the repulsive power of the spring 20 is maximized downwards, and the shutter 5 can be closed by small force. Accordingly, noises and an impulse sound as well as labor can be reduced.

[0004]

However, the conventional shutter storage requires a very large force for the operator to lift it up due to its own weight when the shutter storage is first opened. In addition, when the opening operation ends, a large impact sound may be generated due to the inertial force of the shutter door. This is also the case when trying to perform the closing operation, and countermeasures have been desired.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a shutter storage which reduces the labor of an operator when opening and closing a shutter door and also reduces noise and shock when opening and closing. .

[0006]

In order to solve the above-mentioned problems, the invention according to claim 1 uses the shutter door slidably provided from the front opening of the main body through the top plate to the rear plate side. In the shutter storage for opening and closing the opening, a repulsion unit for selectively generating an upward repulsive force and a downward repulsive force with respect to the sliding direction of the shutter door is provided.

According to a second aspect of the present invention, in the shutter storage according to the first aspect, the shutter door is located between the front shutter door and the rear shutter door via an intermediate open position where the weights of the shutter door and the rear shutter door are balanced. The weight is distributed so as to slide from the front opening of the main body through the top plate to the rear plate side, and the repulsion means does not generate a repulsive force in either the up or down direction at the intermediate open position. .

According to a third aspect of the present invention, in the shutter storage according to the first or second aspect, the repulsion means applies the repulsion force by a twisting force generated by sliding of the shutter door. Is characterized in that.

[0013]

In the shutter storage according to claim 1,
Since the repulsion means that selectively generates the repulsive force in the upward direction and the repulsive force in the downward direction with respect to the sliding direction of the shutter door is provided, for example, when the shutter door is opened, the weight of the shutter door is counteracted. The repulsive force in the upward direction can be utilized, and on the contrary, when the shutter door is closed, the repulsive force in the downward direction can be utilized against the dead weight of the shutter door. The repulsive force in the upward or downward direction can prevent the generation of noise and shock when opening and closing. That is, it is possible to reduce the labor of the operator when opening and closing the shutter door and to reduce the noise and impact when opening and closing.

According to another aspect of the present invention, there is provided a shutter storage cabinet, wherein the shutter door is located at a front position, and the shutter door is located at a front position. The weight is distributed so as to slide toward the rear plate through the repulsion means, and since the repulsion means does not generate a repulsive force in either the up or down direction at the intermediate open position, the shutter is released below the intermediate open position. When the bottom edge of the door is located, an upward repulsive force is generated against the dead weight of the shutter door, and when the bottom edge of the shutter door is located above the intermediate open position, it opposes the dead weight of the shutter door. Then, a repulsive force in the downward direction is generated, so that an operator holding the lower end of the shutter door can perform the opening / closing operation with a constant force.

According to the third aspect of the present invention, in the shutter storage, the repulsion means is an elastic means that gives the repulsion force by the twisting force generated by the sliding of the shutter door, so that there is no particular complicated mechanism. , While reducing the labor of the operator when opening and closing the shutter door,
Noise and impact during opening and closing can be reduced.

In the shutter storage according to claim 4, the repulsion means is a coil spring, and by incorporating it into the shutter storage with a simple mechanism, the labor of the operator in opening and closing the shutter door is reduced. It is possible to reduce noise and impact when opening and closing.

According to another aspect of the present invention, there is provided a shutter storage in which the shutter door is formed by continuously binding a plurality of shutter plates, and the shutter plates are provided with a continuous binding groove so that the shutter plates can rotate relative to each other at both ends in the sliding direction. Since a sprocket having a sprocket groove with which the continuous binding groove engages is provided on the main body, and the repulsion means has a linkage mechanism that generates a repulsive force as the sprocket rotates, the shutter door slides. The rotational force of the sprocket that accompanies the movement can be reliably and easily transmitted to the repulsion means, and thus the upward or downward repulsion force can be reliably and easily obtained.

In the shutter storage according to the sixth aspect of the present invention, the constricted portion is provided on the rotary shaft of the sprocket, and the constricted portion is sandwiched by the split groove for preventing the slip-out. Therefore, the entire structure can be disassembled. It is also suitable for maintenance.

In the shutter storage according to the seventh aspect, since the pair of repulsion means are provided symmetrically with respect to the width direction of the shutter door, the repulsive force can be evenly distributed to the left and right.

It is fixed to 1, 22.

In the retainer 28, the split groove 39 holds the constricted portion 40 of the rotary shaft 25, thereby preventing the rotary wheel 21 and the sprocket 16 from coming off. It should be noted that this removal prevention relationship is relative, and when the left and right retainers 28 are removed, the rotary shaft 25 itself is released from the stop by the stop plate 23 via the rotary wheel 21, and moves to either the left or right. It will come off from the rotation hole 27. That is, the structure using the retaining member 28 allows the entire structure to be disassembled, which is also suitable for maintenance.

FIG. 6 is a perspective view in which the structures of the sprockets 16 and 24 are clarified. Sprocket 16, 24

FIG. 5 illustrates the left side portion of the main body 1 from the front, but the right side portion is also provided with a similar symmetrical structure.

As can be understood from the description of FIGS. 4 and 5, the rotary wheel 21 does not rotate with the rotation of the sprockets 16 and 24, but only the rotary wheel 22 integrated with the sprocket 24 rotates. . As a result, the rotating wheel 2
The coil springs 20 fixed to the coils 1 and 22 are deformed in the twisting direction in association with the rotation of the sprockets 16 and 24.
As a result, a repulsive force is generated in the coil spring 20 in the rotation direction. That is, the rotary wheels 21 and 22 constitute a linkage mechanism for generating a repulsive force in the coil spring 20 as the sprockets 16 and 24 rotate, and the coil spring 20 is one of the characteristic parts of the present invention. Make up.

The coil spring 20 can selectively generate an upward repulsive force and a downward repulsive force with respect to the sliding direction of the shutter door 5. Here, the shutter door 5 extends from the front opening 2 of the main body 1 through the top plate 3 to the rear plate 4 side via an intermediate open position where the weights of the front portion and the rear portion are balanced. The weight of the shutter door 5 can be distributed so as to slide. That is, the coil spring 20 does not generate a repulsive force in either the up or down direction at the intermediate open position. This intermediate open position is generally a position where the lengths of the shutter doors 5 hanging down in the front and rear of the main body 1 are substantially the same.

With this configuration, for example, when the shutter door 5 is closed, the repulsive force of the coil spring 20 is maximum in the upward direction, and an excessive amount of labor is not required to lift the shutter door 5 upward. . Lift this up,
Even if the repulsive force becomes small for a while, the shutter door 5 can be operated with a constant force without any trouble because the weight of the shutter door 5 is reduced. Also, after the repulsive force disappears at the intermediate open position,
This time, the repulsive force in the downward direction increases, so there is no large impact or noise when the opening work is completed. On the contrary, in the state where the shutter door 5 is opened, the repulsive force of the coil spring 20 is the maximum in the downward direction, and an excessive amount of labor is not required to press the shutter door 5 downward. Even if the repulsive force becomes small for a while by pressing it down, the shutter door 5 can be operated with a constant force without trouble because the weight of the shutter door 5 is reduced. Further, after the repulsive force disappears at the intermediate open position, the repulsive force in the upward direction increases this time, so that a large impact and noise are not generated when the opening work is completed.

Although the illustrated embodiment has been described above, the present invention is not limited to the above embodiment, and various changes can be made to the shape of each component.

For example, although the coil spring 20 is used as a simple repulsion means for generating elastic force, the means for generating elastic force is not limited to this.

Further, although the shutter door 5 is constructed by connecting a plurality of shutter plates 13 in a row, the shutter door 5 is not limited to this, and if a repulsive force is generated in the repulsion means by a predetermined means. The object of the present invention can be achieved.

Further, in the above embodiment, the repulsion means using the coil spring 20 is provided symmetrically, but this is a measure for evenly distributing the repulsion force to the left and right, and it is also possible to achieve the purpose with only one. You may be able to
