Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a soundproof bracket for sealing the upper and lower gaps of a movable partition wall for soundproofing.

[Conventional technology]

In this type of soundproof structure, for example,
As shown in the publication, a long sealing member (same meaning as a soundproof bracket) is attached to the lower end of the door (same meaning as a movable partition wall, the same shall apply hereinafter) along the door frontage direction. - The same applies hereinafter) is provided so that it can be moved up and down, and a protruding member is provided so that one end protrudes from the side edge of the door, and when the door is closed, the protruding member is retracted into contact with the door frame or the side edge of the adjacent door to seal the door. A structure in which a member is moved is known.

Furthermore, as shown in Japanese Utility Model Application Publication No. 63-5190, for example, a horizontal rod is provided in the door body so as to be movable in the direction of the frontage of the door, and a vertical rod is provided so as to be movable up and down by the movement of the horizontal rod. There is a known structure in which a long sealing member is attached to the lower end of the cylinder, and the sealing member is moved up and down by an external handle connected to a horizontal rod.

[Problem to be solved by the invention]

By the way, in the former case, the mounting structure is complicated, and one end of the protruding member protrudes from the side edge of the door when the door is opened, so that the appearance is unsightly and unnatural.
In addition, the danger to the human body due to protrusion could not be denied.

In addition, the latter type of door is operated by a handle or handle as a general door element, which eliminates the appearance of discomfort, but since the operating mechanism other than the handle is installed inside the door body, the movable partition wall However, this was limited to those with a laminated structure, leading to an increase in manufacturing costs.

Furthermore, even if the handle is applied to a type in which the upper and lower sealing members are operated simultaneously, the structure cannot be avoided from becoming larger and more complicated. Additionally, it was extremely difficult to add to existing doors, resulting in a lack of usability.

Therefore, this invention has a structure that is easy to install on a movable partition wall, can be easily applied to a type of simultaneous upper and lower operation using one operation part (A), and is highly usable and does not look inferior. The purpose is to provide a soundproof bracket for a partition wall that prevents shadows from forming.

[Means to solve the problem]

In order to achieve the above object, the present invention has a structure in which the bracket attached to at least one of the upper and lower end surfaces of the movable partition wall can be operated from one end side of the bracket, thereby making it possible to attach the bracket to the movable partition wall using a 4M structure. It is intended to be simple, and its features include a fixing bracket with a U-shaped cross section that is fixed to at least one of the upper and lower end faces, and a spring member inside this fixing bracket that is biased outward. Equipped with a movable bracket with a U-shaped cross section,
The approximate center of the movable bracket and the fixed bracket are connected to the side of the link machine, and this link mechanism is provided with an operating link for contracting the link mechanism with its operating end extending toward one end of the bracket in the longitudinal direction. It is in the fact that it is being given.

[Function] According to the present invention, for example, an operation case equipped with an operation handle is embedded and fixed in one example of the left and right ends of a movable partition wall, and operation ronds are provided along the left and right end surfaces of the movable partition wall, so that the operation rond The mounting structure may be such that the operation case and the operation end of the operation link are connected. This simplifies the structure and facilitates attachment to the movable partition wall. By connecting the upper and lower operating brackets to the operating case, the upper and lower movable brackets can be operated simultaneously with one operating member.

When the operation handle is rotated from the soundproof state in which the gap is closed by the movable bracket, the operation link is rotated in the vertical direction and the link FITN is contracted. At the same time, the movable bracket is moved toward the fixed bracket against the biasing force of the spring member, thereby canceling the soundproof state.

Since the link mechanism is connected to approximately the center shaft of the movable bracket, the movable bracket can be moved without deviation. Further, when the operating handle is rotated from the soundproofing state, the movable bracket projects outward by the biasing force of the spring member, the gap is closed, and the soundproofing state is achieved.

〔Example〕

1 to 7 show an embodiment of the present invention.

This shows an example of application to a foldable movable partition wall. As shown in FIG. 1, a movable partition wall 68 is connected with a hinge 10 between the upper rail 2 and the lower rail 4, making it foldable. It is provided. The movable partition walls 6, 8 are suspended at their upper ends by upper runners 12.12, and supported at their lower ends by lower runners 14.14 located on the same axis as the upper runner 12. Soundproof brackets 20 are provided on the upper and lower end surfaces of each of the movable partition walls 6 and 8, respectively, to close the gap G between the movable partition walls 6 and 8. Each soundproofing bracket 20 is configured such that soundproofing and release operations can be performed simultaneously on the upper and lower sides via an operating rod 24 in an operating case 22 embedded and fixed in one of the left and right ends of each movable partition wall 6, 8. The operation using the operation case 22 is performed using the movable partition wall 6.
This is done by rotating the operating handle 25 facing outward on both sides.

As shown in FIGS. 2 to 5, each soundproof bracket 20 includes a long fixed bracket 26 with a U-shaped cross section fixed to the upper and lower end surfaces of the movable partition walls 6 and 8;
It is basically connected to a long movable bracket 28 which has a U-shaped cross section and is provided inside the housing 6. Identification bracket 2
Support shafts 30 are erected at intervals in the longitudinal direction on the bottom surface of the movable bracket 6, and correspondingly, a ventilation hole 32 for inserting the support shafts 30 is formed on the bottom surface of the movable plaque notebook 28. There is. Prior to mounting the movable bracket 28, a spring member 34 is fitted onto the support shaft 30, thereby urging the movable bracket 28 outward. Further, the movable bracket 28 is detachably stopped after being attached to the support shaft 30.

The fixed bracket sole 1 26 and the movable bracket 2 are connected by a link machine 36. The link mechanism 36 is composed of a short link 38 and a long operation link 40 as an operation member for contracting the link mechanism 36. The short link 38 is rotatably supported by a pin 44 on a mounting piece 42 fixed to the bottom surface of the movable bracket 28 substantially in the center, and the other end is a long mounting piece fixed to the bottom surface of the fixed bracket 26. It is rotatably supported on one end side of 46 by a pin 48. On the other hand, the operation link 40 connects one end to the link 3
8 is rotatably supported by a pin 50.50 on the other end side of the mounting piece 46 at a position approximately equivalent to the mounting end for the movable bracket 26 of the link 38, and the plaque is moved by an appropriate dimension from the mounting end of the link 38 for the fixed bracket 26. It is connected to the link 38 at a position close to the second toe 28 by a pin 52 in a cross state. The connecting hole 38a, which can be formed on either side, and the connecting hole of the link 38 on the movable bracket 28 side are elongated in order to absorb displacements during contraction and expansion.

The other end of the operation link 40 extends to one end in the longitudinal direction of the bracket, and has an insertion hole 40a midway through which the support shaft 30 is inserted.

The operating end 40b serving as the free end of the operating link 40 includes:
A contact surface 40 on which the operating rod 24 comes into contact is formed with a large engaging recess 40c on which the operating rod 24 is held.

and the connection position (pin 52) with the operation link 40 and the pin 5
0 and the pin 52 is appropriately determined in consideration of the stroke amount of the operating rod 24, the elasticity of the spring member 34, the operability of the operating case 22 based on the rotational moment of the operating link 40, etc. It is. When the operating force is removed by moving the operating rod 24 in the direction of the arrow M from the soundproof release position OP, the movable bracket 2B is projected outward by the biasing force of the spring member 34, and its upper end touches the stepped portion 2a of the rail 24. ，
4a to close the gap G in an airtight state. Since the movable bracket 28 has a U-shaped cross section, the movable partition wall 6
Even if there is a deviation in the positional dimensions in the front and back directions, airtightness can be achieved because either the front or rear edge of the U-shape is in contact with the rail.

Mounting portions 54 and 54 are formed at the upper and lower ends of the opposite end of the fixing bracket 26 from the operating side, respectively, for mounting the upper runner 12 and the lower runner l4 from the outside. The upper runner l2 is comprised of, for example, a wheeled runner main body 56 having a helical shaft 56a on the lower surface, and a runner support portion 58 that is integrated with and competes with the helical shaft 56a. The runner support portion 58 is formed with a set screw portion 60 for securing the runner after installation. The set screw portion 60 can include a set screw 62 and a screw insertion hole 64 formed in the lower part of the runner support portion 58 in the longitudinal direction.

The mounting part 54 can be composed of, for example, a mounting part main body 66 fixed to the end of the nationally specified bracket 2G, and a threaded part 68 screwed into the set screw part 60. Mounting part main body 66
A strike bar piece 70 for positioning the upper runner 12 is connected to the deep end of the runner. The mounting portion main body 66 preferably has a shape that can accommodate the runner support portion 58 without wobbling, and has a groove width equivalent to the width of the narrow width portion 58a to correspond to the runner support portion 58 having a convex cross section, for example. It can be formed into a substantially C-shaped channel material having a cavity large enough to closely accommodate the wide portion 58b. After mounting, the runner support member 58 is attached to the protrusion 6 of the mounting portion main body 66.
6a prevents it from coming off in the height direction. Threaded part 68
For example, a nant that is screwed onto the set screw 62 can be used, and in this case, a through hole 70a through which the set screw 62 is inserted may be formed in the stopover piece 70 and the set screw 62 may be inserted therethrough. On the other hand, a notch 72 with a width slightly larger than the narrow width part 58a of the runner support part 58 is formed at a corresponding position of the movable bracket 28, thereby allowing the upper runner l2 to be mounted and moved. Therefore, the upper runner 12 or the lower runner 14 can be easily attached from the outside of the fixed bracket 26 by sliding the runner support part 58 onto the mounting part main body 66 and screwing the setscrew 62 into the threaded part 68. It can be attached and detached. Further, the cutout portion 72 prevents the upper runner 12 or the lower runner I4 from interfering with the movement of the movable bracket 28 into and out. Note that the mounting portion main body 66 may have a shape in which the runner support portion 5 is fitted from the upper surface side of the fixed bracket 26, and the threaded portion 68
