Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sealing device for sealing gaps that are created above and below a movable partition panel when it is installed.

Various types of sealing devices have been proposed in the past for the top and bottom of panels that are movably suspended along rails installed on the ceiling, but all of them are difficult to operate, and it is very difficult to put in and take out the sealing material when installing the panel. It was a difficult task.

The purpose of the present invention is to eliminate the above-mentioned drawbacks of conventional sealing devices, and to provide a sealing device that allows the sealing material to be taken in and out with a single touch with a light force, and that can reliably seal the gap between the ceiling rail and the floor surface. It is.

The feature of the sealing device for a movable partition according to the present invention is that an upper sealing material for sealing the gap at the top of the panel and a lower sealing material for sealing the gap at the bottom of the panel are placed inside the panel at the top and bottom of the panel. An operating rod is disposed vertically slidably between the retracted position and the sealed position protruding from the panel, and moves the sealing members to the sealed position and the retracted position at the same time. a first elastic member that is attached and operable from an end face of the panel and biases one of the upper sealant and the lower sealant toward a protruding position; and a first elastic member biasing the other toward a retracted position. A second elastic member is provided, and the biasing force of the second elastic member is made slightly larger than the biasing force of the first elastic member.

That is, in the present invention, the first elastic member and the second elastic member act in opposite directions and cancel out their effects, so that the biasing force of the second elastic member is caused by the biasing force of the first elastic member. The sealing material is retracted into the panel because it is made slightly larger than the biasing force, but when sealing, a light force equivalent to the difference in the biasing forces of these elastic members is applied to the operating rod. The sealant is thus in the sealing position.

The illustrated embodiment will be described below. In the figure,
Fig. 1 shows the state when the panel is moved, and Fig. 2 shows the state when the panel is installed and the gaps above and below it are sealed.

In the figure, 1 is a movable partition panel, 2 is a hanging wheel, and 3 is a rail. At the top and bottom of the panel 1, an upper sealant 4 for sealing the gap at the top of the panel and a lower sealant 5 for sealing the gap at the bottom of the panel are placed in the retracted position (the position shown in Figure 1) into the panel. )
and a sealed position protruding from the panel (the position shown in FIG. 2) so as to be slidable in the vertical direction.

In the illustrated embodiment, the seals 4, 5 are slidably supported on the side frames 6, 6 of the panel. The upper sealing member 4 is provided with downwardly extending sliding rods 7, 7, and a transverse member 8 is fixed between the sliding rods 7, 7. The sliding rods 7, 7 are slidably housed in guide rods 9, 9 having a substantially square cross section.

On the other hand, the lower sealing material 5 has a sliding rod 1 extending upward.
0 and 10 are provided, and a horizontal member 11 is fixed between the sliding rods 10 and 10.

The above-mentioned sliding rods 10, 10 are guide rods 1 having an approximately square cross section.
2 and 12 so as to be slidable.

In order to simultaneously move the upper and lower sealants 4 and 5 to the sealing position (Fig. 2) and the retracted position (Fig. 1),
An operating rod 13 is pivotally mounted in the panel by a pivot 14, which in the illustrated embodiment can be operated from the end face of the panel by connecting a suitable tool to the operating rod 13. . The operation 13 and the upper sealing member 4 are connected by a wire 15, and the operating rod 13 and the lower sealing member 5 are connected via a toggle link 16. The wire rod 15 may be a rigid body, but may also be a wire or the like.

A first elastic member that always biases one of the upper sealant 4 and the lower sealant 5 toward the protruding position, and a second elastic member that always biases the other sealant toward the retracted position are provided. It will be done. In the illustrated embodiment, the first elastic member is composed of springs 17, 17 which act to constantly push the sliding rods 7, 7 upward, and which act to always project the upper sealing member 4 towards the sealing position. . The second elastic member also comprises a spring 19 acting on an actuating rod 18 extending upward from a transverse member 11 connected to the lower sealing member 5. The operating rod 18 is guided so as to be vertically slidable in a guide hole provided in the horizontal frame 20 of the guide rods 12, 12, and is constantly pushed upward by the elastic force of the spring 19 to constantly pull in the lower sealing member 5. Push up into position.

The biasing force of the second elastic member, that is, the spring 19, is slightly larger than the biasing force of the first elastic member, that is, the springs 17, 17, so that the upper and lower sealing members 4, 5 are always shown in FIG. It is held in the retracted position.

In the above sealing device, the springs 17 and 1
Since the biasing force of spring 19 is configured to act as a rotational force in the opposite direction to the operating rod 13, and the biasing force of spring 19 is set to be larger than the biasing force of springs 17, 17, normally, No special locking means are required, the sealing material is held within the panel and can be operated with a light force corresponding to the difference in the biasing forces of the springs 17 and 19 when sealing the upper and lower gaps. However, when the sealing material is projected by the operating rod, the toggle link 16 passes beyond its dead center and is locked in that position. However, if a flexible material such as wire is used as the above-mentioned wire, the springs 17, 17 will also act as adjusters to absorb the slope of the ceiling surface, etc.
There is no need to separately provide a spring or the like as in the conventional case. Further, as in the conventional case, if the sliding rods 10, 10 and the lower sealing member 5 are integrated via an elastic body such as a spring, the inclination of the floor surface can be absorbed.

As described above, the movable partition sealing device according to the present invention can move the sealing material in and out with extremely light force, and can reliably seal the gap between the ceiling rail and the floor.
