Description

[Detailed explanation of the idea] The present invention relates to an improvement in the suspension structure of a moving wall.

In the conventional models of this type (Special Publication No. 48-21247, Special Publication No. 57-431), the movable wall is suspended from the ceiling at two places on the left and right by suspension wheels, and the suspension wheels are rotatable by suspension shafts. There is one in which an upper truck and a lower truck are connected to each other, and the lower truck is freely movable within a guide rail provided along the left and right direction at the upper end of a moving wall. These are convenient for storing the movable wall at a predetermined location indoors, but when running on straight rail sections or rail branch sections,
The hanging wheel rolls too much in the left and right directions of the moving wall, making the direction uncertain, which impedes the smooth running of the wall.
The drawback was that movement was unstable.

It is an object of the present invention to provide a movable wall suspension structure that eliminates the above-mentioned drawbacks and makes it possible to restrict the movement of a suspended vehicle relative to a wall by a simple operation if necessary.

In view of the above object, the configuration of the present invention is such that the movable wall is suspended from the ceiling rail at two locations on the left and right through suspension wheels, and each of the two suspension wheels is connected to an upper truck, a lower truck, and the like so as to be rotatable. and a connecting rod that makes the lower carts of the two hanging cars immobile relative to each other; an engaging piece protruding from the lower truck of the hanging car; a hook provided on the movable wall side within a recess of the movable wall in which the lower truck is accommodated and which can be freely engaged with and detached from the engaging piece; and a hook operation section for engaging and disengaging the.

An embodiment of the present invention will be described below based on the drawings.

In FIGS. 1 to 3, a ceiling rail 1 having a rip-groove cross-section and a steel shape is provided with its opening facing downward, and a movable wall 2 is attached to the rail on the left and right sides.
It is suspended via a suspension wheel 3 at a certain point. The movable wall 2 has recesses 21 on its upper surface near its left and right ends, and I-shaped beam-shaped guide rails 22 are fixed with screws to the bottoms of these recesses.

The suspension wheel 3 consists of an upper truck 31, a lower truck 32, and a suspension shaft 33 rotatably connected to both.
The upper truck 31 has a large number of spherical rollers 31b arranged on the lower surface of a disc-shaped main body 31a so as to be rotatable in all directions. On the other hand, in the lower truck 32, a main body 32a having a grooved steel cross section has its opening facing downward and its length direction along the length direction of the recess 21.
is housed within. The two left and right lower truck bodies 32a, 32a are connected by a connecting rod 9, so that a constant distance is always maintained and they cannot be displaced relative to each other. Furthermore, short cylindrical rolls 32b having rotation axes perpendicular to the wall are installed at four locations in the lengthwise direction of each lower truck main body 32a, facing each other inside both flange portions of the main body 32a. The roll 32b is
The movable wall 2 is suspended and moved while its upper surface rolls on the lower surface of the upper flange of the guide rail 22.

Therefore, the lower truck main body 32a of one of the two suspended wheels has an engaging piece 34 at one end (right side in FIG. 3) in the length direction thereof toward one side perpendicular to the length direction. It is installed protrudingly. Further, a contact piece 4 is provided on one end side of the recess 11 to abut against the main body 32a of the lower truck 32 to regulate its position when the lower truck 32 moves toward the one end side.

The locking portion 5 can be hooked onto the engagement piece 34. That is, the locking portion 5 is pivoted at its intermediate portion by a pin 52, and a hook 51 whose one end can be hooked to the engagement piece 34 is hooked at the other end by a leaf spring 53. It gets repelled in that direction.
The hook 51 is operated via a hook operation section 6 consisting of an arm 61 protruding from the upper surface of the hook, a threaded rod 62 screwed into the arm 61 at right angles, and a wire 63 connected to the threaded rod 62. The movable wall 1 is made swingable via a guide pulley 7 by a tensioning device 8, such as a French drop, provided at one end of the movable wall 1.

Next, the mode of use will be explained. As is well known, the movable wall 2 is a cross-shaped, T-shaped, or L-shaped wall installed on the ceiling.
It is possible to freely run along the rail 1 which is branched into a letter shape. However, when passing through a branch point, the hanging wheel 3 moves freely in the length direction of the wall, so there is a large degree of freedom of movement, so the direction of movement is not constant. Therefore, in order to fix the hanging wheel 3 to the wall 1, the tensioner 8 is operated to activate the hook operation part 6 to loosen the wire 63, and the hook 51 is pulled by the spring 53.
It is rotated counterclockwise in FIG. 3 by the elastic force of , and is locked by the engagement piece 34.

Next, when the wall 1 approaches the target position, the hook 51 is disengaged. To do this, by pulling the wire 63 by reversely operating the pulling tool 8,
The hook 51 is rotated clockwise against the elastic force of the leaf spring 53.

Here, in order to bring the suspension wheel 3 to either end of the movable wall recess 11, the frictional resistance between the upper truck 31 and the ceiling rail 1 must be made slightly smaller than the frictional resistance between the lower truck 32 and the guide rail 22. You can set it to a large value.

The tensioning tool 8 may be any other device than the one described above, as long as it can be operated with a single touch.

The length of the connecting rod 9 may be adjustable, such as a turnbuckle.

Since the present invention is constructed as described above, during the movement of the movable wall, the hanging wheel is prevented from rolling against the moving wall as necessary, and the hanging wheel does not wobble during travel, making it possible to run smoothly. In addition, because the distance between the two hanging wheels is always kept constant, it is extremely easy to store many movable walls stacked in the corner of a room orthogonally to the two parallel rails. .
