Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a moving partition panel device suspended so as to move along a guide rail laid on a ceiling, and more particularly to a moving partition panel device that reduces noise during movement.

[0002]

[Prior Art]

 FIG. 3 is a schematic view of a conventional moving partition panel, in which a guide rail (102) having a hollow rectangular tubular cross section with a longitudinal groove at the center of the lower surface is laid on the ceiling (101), and the partition panel ( Hereinafter, the wheels (104) of the runners attached to both ends of the upper edge of the (103) (103) are rolled onto the inner surface of the lower side of the guide rail (102) to move the panel (103) to the guide rail (102). It is made to move along.

In the conventional moving partition device, since the wheels (104) and the guide rails (102) are both made of steel or metal such as aluminum, when moving the panel (102). In addition, the wheels (104) make rolling contact with the guide rails (102) and generate noise. In residential buildings such as condominiums, this noise can be a nuisance to residents on the upper floors and adjacent rooms, causing trouble for residents, so it is necessary to reduce noise.

Conventionally, in order to reduce noise, a wheel made of an elastic material such as rubber or plastic is used instead of the metal wheel (104), or a guide rail (102) on which the wheel (104) rolls. The inner surface of) is covered with a plastic sheet, or the entire guide rail (102) is formed as a plastic molded product.

Further, as shown in FIG. 4, a guide rail (102) is attached to a structural member (105) mounted on a ceiling (101) via cushioning materials (106) (107) such as anti-vibration rubber. It is also installed to block the vibration of the guide rail (102) from being transmitted to the building.

[0006]

[Problems to be solved by the device]

 The method of using rubber or plastics as the material of the wheel (104) has a high effect of preventing noise, but since the strength is lower than that of a metal wheel, when the panel (103) is heavy. There is a problem that it is deformed and it becomes impossible to move smoothly, or it is worn relatively early and its durability is low.

The means for covering the inner surface of the guide rail (102) with a plastic sheet is laborious and expensive to process, and has a problem in durability, and the entire guide rail (102) is covered with a plastic sheet. Again, the means of making is less suitable than a metal guide rail and is unsuitable if the panel (103) is heavy.

That is, although the wheels (104) and the guide rails (102) are made of rubber or plastics, they are suitable for lightweight partitioning devices such as curtains and relatively small sliding doors, but they are made of large metal. There is a problem in durability when suspending and moving the panel because of insufficient strength.

The means for mounting the guide rail (102) via the cushioning materials (106) and (107) has a small elastic coefficient as the cushioning materials (106) and (107) in order to obtain a sufficient vibration isolation effect. It is necessary to use the one that has a large amount of deflection with respect to the load. In this case, when the weight of the panel (103) is applied, the position of the guide rail (102) is lowered, and there is a problem that a step is formed at the joint between the adjacent guide rails.

That is, when the movement distance of the panel (103) is long and it is not enough with only one guide rail, and when a plurality of guide rails (102) are connected in the length direction, as shown in FIG. When the panel (103) moves to the vicinity of the joint, the guide rail (102) on the side where the weight is applied becomes lower than the adjacent guide rail, and a step is formed at the joint.

When such a step is generated, the runner's wheel (104) is caught and cannot pass, or even if it can pass, a large shock or impact noise is generated, and smooth movement is impossible. There is a problem. Therefore, in order to always hold the adjacent guide rails at the same level, it is necessary to provide a means such as attaching a connecting tool to the joint portion, which is a troublesome assembling process.

An object of the present invention is to provide a moving partition panel device which does not have these inconveniences and which reduces noise during movement.

[0013]

[Means for Solving the Problems]

 The present invention for achieving the above object is configured as follows.

[0014] In a moving partition panel device in which a guide rail laid on the ceiling supports a wheel of a runner mounted on the upper edge of the panel, and the panel is hung so that the panel can move along the guide rail, The moving partition panel device, wherein the lower end of the hanging shaft is attached to the upper edge of the panel via an elastic cushioning material.

A vertical through hole is provided at the upper edge of the hollow panel, and a suspension shaft having a widened flange at the lower end inserted into the panel is loosely fitted in the through hole to allow It is desirable to sandwich an elastic cushioning material between the inner surface and the flange.

The elastic cushioning material may be a cylindrical rubber or urethane block having a through hole at the center through which the suspension shaft passes.

The elastic cushioning material may be a metal spring.

[0018]

[Action]

 The vibration generated by rolling of the runner wheels is usually transmitted to the panel via the suspension shaft and amplified by the resonance action, which increases the noise level. Noise is reduced by interposing an elastic cushioning material in the engaging portion between the suspension shaft and the panel to prevent the noise from being amplified.

[0019]

【Example】

 FIG. 1 is a vertical side view of an embodiment of the present invention, and FIG. 2 is a partially cutaway front view of the same embodiment.

The guide rail (2) laid on the ceiling (1) is made of metal such as steel or aluminum, has a hollow rectangular cross section, and has a longitudinal groove formed in the center of the lower surface. .. The inner surfaces on both sides of the groove form rail surfaces (3) on which the wheels (8) of the runner (7) roll.

The panel (4) is formed in the shape of a box having a hollow structure, through holes (5) are provided near both ends of the upper edge thereof, and the suspension shafts (6) are inserted therein. The through hole (5) has a larger diameter than the outer diameter of the suspension shaft (6), and the suspension shaft (6) can be loosely fitted so as not to contact the edge of the through hole (5).

The upper end of the suspension shaft (6) is inserted into the guide rail (2) through the groove on the lower side of the guide rail (2), and the runner (7) is attached to the suspension shaft (6). When the guide rail (2) is installed in a straight line over the entire length, the suspension shaft (6) and the runner (7) may be fixed, but the guide rail (2) has a curved portion. In some cases, the runner (7) is pivotally mounted so that it can rotate about the axis of the suspension shaft (6).

A pair of front and rear metal wheels (8) are rotatably supported at the left and right ends of the runner (7). Each wheel (8) rolls on the rail surface (3) of the guide rail (2).

On the other hand, a threaded portion (9) is provided at the lower end of the suspension shaft (6) extending from the through hole (5) at the upper edge of the panel (4) into the panel (4), and the nut ( The washer (11) and the flange (12) can be fitted on the upper side by screwing the (10).

A cushioning material (13) made of an elastic material is sandwiched between the flange (12) and the inner surface of the upper edge of the panel (4) to reduce the weight of the panel (4) and the cushioning material (13). Through the wheel (8) of the runner (7). As the cushioning material (13) in the embodiment, a vibration damping rubber formed in a cylindrical shape having a through hole through which the suspension shaft (6) is inserted is applied in the center. If necessary, a cylindrical elastic body that intervenes between the through hole (5) and the suspension shaft (6) is provided as a part of the cushioning material (13) at the upper end of the cushioning material (13). You may install in series.

When the panel (4) constructed as described above is moved along the guide rail (2), the wheels (8) of the runner (7) and the rail surface (3) of the guide rail (2) are both made of metal. Since it is manufactured, the vibration due to the rolling of this portion is generated as in the conventional example of FIG.

Since the panel (4) is formed in the shape of a hollow box, the suspension shaft (6) and the panel (4) are directly connected by a rigid structure like a conventional moving partition panel. Then, the vibration transmitted from the suspension shaft (6) is amplified by the resonance action of the panel (4), and a large level of noise is generated.

However, in the present invention, the suspension shaft (6) and the panel (4) are not directly connected to each other, and the cushioning material (13) made of an elastic material is interposed between the suspension shaft (6) and the panel (4). The vibration transmitted from (8) to the suspension shaft (6) via the runner (7) is absorbed and blocked by the cushioning material (13) and is not transmitted to the panel (4).

The inner diameter of the through hole (5) at the upper edge of the panel (4) is made larger than the outer diameter of the suspension shaft (6), and the suspension shaft (6) and the panel (4) are formed in this portion. It prevents the vibration from being transmitted due to the contact with.

Therefore, since the vibration generated by the rolling of the wheel (8) is not transmitted to the panel (4), it is possible to prevent the generation of a large level of noise due to the resonance action of the panel (4). , The noise level is significantly reduced compared to the conventional moving partition device.

In the illustrated embodiment, a cylindrical vibration-proof rubber is used as the cushioning material (13), but other elastic bodies such as a metal coil spring or leaf spring may be used. ..

Although the above embodiment has been illustrated and described as a manual type in which the panel (4) is manually moved, the present invention is an automatic traveling type moving partition panel device having a drive device in the runner (7). It is also possible to apply.

[0033]

[Effect of the device]

 The present invention has the following effects. (a) The suspension shaft hanging from the runner and the panel are attached via a cushioning material made of an elastic material, and the vibration when the wheels of the runner roll on the guide rail is blocked. It is possible to prevent a large level of noise generated by being amplified by the resonance effect of the panel.

(B) The wheels and guide rails can be made of durable metal, and the noise when the panel is moved can be reduced.

(C) The same runner and guide rail as the conventional moving partition device can be used as they are.

(D) Since the guide rail can be fixed to the ceiling without interposing a cushioning elastic body, a step does not occur at the joint due to the weight of the panel, and smooth movement can be ensured. it can.
