Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a moving partition for movably suspending a large moving panel from a ceiling surface so as to enhance sound insulation and sealing of the moving panel. About corner closers.

2. Description of the Related Art In a moving partition, a corner closer has been proposed to improve the sound insulation and the airtightness of a moving panel (for example, Japanese Utility Model Laid-Open No. 54-154546).

This is a movable member that is arranged to move forward and backward along the peripheral end face of the moving panel, and is bent along the corners of the peripheral end face of the moving panel, and both ends are slidably inserted into adjacent movable members. The main body is the closer body. A tight material with a fin-shaped cross section is inserted outwardly on the movable member,
Another tight material of the same shape is attached to the outer surface of the closer body. The closer body advances diagonally outward from the corner of the moving panel by advancing each movable member to the outside of the moving panel. At this time, the tight members attached to the moving member and the closer body are It can adhere to the surrounding floor, wall and ceiling. Therefore, the entire circumference of the moving panel, including its corners, can be continuously sealed through the tight material, and high sound insulation and airtightness can be achieved.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention According to such a conventional technique, since the movable member and the tight member attached to the closer body are formed to have a fin-shaped cross section, the mechanical strength thereof is small, and the tight member can be applied to the floor surface or the like. Since they cannot be firmly adhered to each other, there is a problem that the performance is insufficient in terms of sound insulation and hermeticity when used for a large moving panel. Further, when the closer body is driven through the adjacent movable member, the closer body may not move smoothly, which causes an unpleasant squeak noise or a problem that the closer body is deformed. When the closer body comes into contact with a movable member through a large contact area, friction resistance increases and it becomes difficult to slide, and it is difficult to take measures such as applying lubricating oil from the viewpoint of giving importance to appearance. This is because there is a situation.

Therefore, in view of the problems of the prior art, an object of the present invention is to specify the shape of a tight material attached to a movable member and the shape of a closer body, and to project a guide rib that guides the closer body at a specific position of the movable member. By doing so, it is an object of the present invention to provide a corner closer of a moving partition that can improve sound insulation and airtightness and smooth the movement of the closer body.

Means for Solving the Problems A structure of the present invention for achieving the above object is a movable member which is made of an extruded shape member and is arranged so as to be movable back and forth along a peripheral end surface of a movable panel, and each leg portion of the movable member. A pair of tight members with an M-shaped cross-section that are mounted outward at the tip of the groove and bend along the corners of the peripheral end surface of the moving panel, and both ends are slidable to the adjacent movable members. It consists of a closer body to be inserted and a packing material attached to the outer surface of the closer body, the closer body is formed in an inward groove-shaped cross section, and the movable member is formed on the inner surface of each leg portion and the upper surface of each dovetail groove. The gist of the invention is to provide a guide rib that guides the closer body.

Action According to the structure of the invention, since the tight member attached to the movable member has an M-shaped cross section, the tight member has a large strength, and by advancing the movable member, the tight member adheres sufficiently strongly to the corresponding floor surface or the like. In addition, since the left and right legs and the central hanging part can independently form a triple shield structure, it is possible to easily achieve extremely high sound insulation and airtightness as a whole. .

On the other hand, the closer body is brought into contact with the movable member through the minimum contact area by being guided by the guide ribs protruding from the inner surface of each leg of the movable member and the upper surface of the dovetail groove for mounting the tight material. Therefore, it is possible to always operate smoothly without taking any special lubrication means.

Example Hereinafter, an example will be described with reference to the drawings.

The movable partition corner closer mainly includes movable members S, S ... Arranged on the peripheral end surface of the movable panel P and closer bodies 11, 11, ... Mounted on the corners of the movable panel P (see FIG. 1). , FIG. 2).

The moving panel P and the floor surface F, the ceiling surface C, the wall surfaces W, W (hereinafter, simply referred to as the floor surface F, etc.) have substantially the same gaps d, d ... Making it easy. The upper, lower, left and right peripheral end surfaces of the moving panel P are
Grooves P2, P2 ... For accommodating the movable members S, S ... Are formed (FIG. 3 but the groove P2 on the floor F side is shown in FIG. 3).

The movable member S is an extruded shape member having a channel-shaped cross section that opens toward the outside of the moving panel P. The movable member S is the top surface
Legs S1 and S1 are vertically provided on both sides of S2, and a dovetail groove C3 is formed at the tip of each leg S1, and the inner surface of the middle portion of each leg S1 and the upper surface of each dovetail groove C3 are Guide ribs S1a and S3a are formed in a protruding manner. Further, a pair of tight members S4 and S4 having an M-shaped cross section are mounted outward in the dovetail grooves S3 and S3. Both ends of each movable member S are formed on end faces Sa and Sa of 45 degrees (Fig. 1), and the distance between the end faces Sa and Sa, that is, the length L of the movable member S, corresponds to the corresponding moving panel. It is almost equal to the length of each side of P (Fig. 2). The movable members S, S ...
The driving devices K, K support the movable panel P so that it can move in parallel in the outer peripheral direction of the movable panel P.

Each drive device K includes a worm gear mechanism K1 that is rotated from the surface of the moving panel P, and feed screw mechanisms K2 and K2 that rotate in the forward and reverse directions in the arrow R direction in FIG. 2 by the worm gear mechanism K1.
, And driving members K3, K3, which connect the distal end portion to the movable members S, S ... by screwing the base end portion to the feed screw mechanisms K2, K2. With the rotation of the screw mechanism K2, it moves back and forth in the longitudinal direction. However, the feed screw mechanism K2 screwed with the horizontal drive member K3 converts the central axis of rotation by 90 degrees with respect to the other feed screw mechanisms K2 and K2 via the bevel gear mechanism K4. The drive members K3, K3 ...
The movable members S, S ... That are connected to the first end seal the gaps d through the tight members S4, S4 in the forward limit (third part).

In the above description, the gaps d, d, ... Between the moving panel P and the floor surface F, etc. are assumed to be substantially the same, but even when they are different, for example, the driving members K3, K3 of the driving device K are used. This can be easily dealt with by interposing a compression spring in the middle part of. Since the compression spring can adjust the difference in the movement stroke of the movable members S, S ..., The movable members S, S ... Are securely brought into close contact with the floor surface F or the like even for different gaps d, d. Because you can. Also at this time, each closer body 11 can automatically follow the movement of the adjacent movable members S, S, and can completely seal the gap D between them. Further, the different gaps d, d ... Adjust the feed amount of the feed screw mechanisms K2, K2 ...
This can be easily dealt with by changing the moving stroke of the.

EFFECTS OF THE INVENTION As described above, according to the present invention, the tight material mounted on each movable member is formed in an M-shaped cross section, so that the tight material has a large strength and is sufficiently strong against the floor surface and the like. Since it is possible to obtain a triple-layered shielding structure by closely adhering to each other, it is possible to easily realize high sound insulation and airtightness of the moving panel, and also to form the closer body in an inward groove-shaped cross section, By providing a guide rib that guides the closer body at a specific position inside the movable member, the closer body can contact and slide with respect to the movable member through a minimum contact area, so that it is exceptional. There is an excellent effect that a smooth movement can always be realized without applying a lubricating means.

Since the tight member is attached to the movable member through the dovetail groove, the attaching work is extremely easy and the number of assembling steps can be minimized.
