Reference numeral 20 in the figure denotes a push button for releasing the reverse rotation stop. However, in the conventional structure including the above structure, since both the pressure contact bodies 11 and 12 can be moved by the same distance, the size of the gap that can be closed by the pressure contact bodies 11 and 12 is not the same. There is a restriction that it must not be.

[Object of the Invention]

The present invention has been made in view of the above points, and an object thereof is to reliably shut off these gaps even if the dimensions of the gaps on the ceiling side and the floor side are different. An object is to provide a movable partition press-contacting device.

DISCLOSURE OF THE INVENTION

Thus, the present invention provides a movable partition pressure contact device in which the pressure contact bodies that are vertically slidable are respectively arranged above and below the partition panel, and each pressure contact body is spring-biased in the protruding direction from the panel. A wire, the other end of which is connected to the other pressure contact member, a movable pulley on which the wire is hung, and a moving mechanism which moves the movable pulley to apply tension to the wire. Characterized by being provided, by moving the movable pulley and applying tension to the wire, both pressure contact bodies that are spring-biased in the protruding direction from the panel are drawn together into the panel. In this case, since one end of the wire is connected to one pressure contact body and the other end is connected to the other pressure contact body, even if the sizes of the gaps in which both pressure contact bodies are closed are different, The amount of movement of the pressure body on the hearing side is made automatically larger than the amount of movement of the other pressure member. The present invention will be described in detail below with reference to the illustrated embodiments.
The figure shows the basic form of the present invention, in which the upper and lower ends of the panel 1 are slidably arranged in the upper and lower portions, respectively, and the springs are arranged together.
Connect each end of one wire 13 to the pressure contact bodies 11 and 12 that are biased in the protruding direction from the panel 1 by 15, 15 and connect both pressure contact bodies 11 and 12 with the wire 13. A movable pulley 2 which is movable in the width direction of the panel 1 is hung in the middle of the wire 13, and the movable pulley 2 is moved so that the upper and lower pressure contact bodies 11 and 12 are simultaneously moved in opposite directions. ing. In the figure, 22 is each pressure contact body 11,12.
Is a pair of idle pulleys arranged near the movable pulley 2, and a pair of idle pulleys 21 are arranged near the movable pulley 2.
2 is fixed to panel 1. An example of the moving mechanism 3 for moving the movable pulley 2 is shown in FIGS. 2 and 3. The moving mechanism 3 embedded in the side end surface of the panel 1 rotatably supports the above-described pair of idle pulleys 21, 21 by the shafts 35, 35, and the frame 30 fixed to the panel 1 and the frame 30.
A pair of levers rotatably supported together by a shaft 36
The movable pulley 2 is composed of 31,32 and a toggle link 4 which is constructed by connecting two links 41, 42 with a shaft 43 and whose one end is supported by the shaft 36. A shaft 33 that is inserted into the other end of the shaft 33 and is slidable in a long hole 34 formed in the frame 30.
Supported by. Reference numeral 37 in the figure denotes a drop-out prevention pin provided on the toggle link 4 and the frame 30 to prevent the wire 13 from coming off from the movable pulley 2 and the idle pulleys 21, 21. When both of the press contact members 11 and 12 are protruding from the panel 1 and press contact with the ceiling surface and the floor surface, respectively, the movable pulley 2 is at the position shown by the solid line in FIG. 2 and the toggle link 4 is bent. It is in a broken state. Also, both levers 31,3
2 is a position along the side end surface of the panel 1. To release this pressure contact state, the lever 31 may be pulled out and rotated. With the rotation of the lever 31, the toggle link 4 is such that the link 41 is pushed by the lever 31 and rotates about the shaft 36.
The shaft 33 arranged at the movable end of the toggle link 4 has a long hole 34.
Move along. In other words, the movable pulley 2 moves,
Both press-contact bodies 11 and 12 are moved in the direction of being drawn into the panel 1 through the wire 13. The shaft 43 connecting the two links 41 and 42 of the toggle link 4 is the shaft 36 and the shaft 33.
A stopper provided on the frame 30 beyond the line connecting
When the link 42 comes into contact with 38, the toggle link 4 is held in the state shown by the chain line in FIG. 2 even if the lever 31 is returned. Both the pressure contact bodies 11 and 12 are held in a state of being drawn into the panel 1. Even if the sizes of the gaps on the ceiling side and the floor side where both the pressure contact bodies 11 and 12 are closed are different, in the process of pulling in the both pressure contact bodies 11 and 12, the pressure contact body 11 having the larger gap when viewed from the movable pulley 2. The wire 13 on the 12 and 12 side is sent to the pressure contact bodies 12 and 11 with the smaller clearance, and both the pressure contact bodies 11 and 12 are pulled into the panel 1 to release the pressure contact. It Further, even if only one of the pressure contact bodies 11 and 12 is pulled in first, the other pressure contact body 12 and 11 is finally completely retracted. The lever 32 may be rotated in order to return the toggle link 4 holding the state indicated by the chain line in the figure to the position indicated by the solid line again for pressure contact, since the dead point is exceeded. When the lever 32 is rotated so as to be pulled out, the engaging pin 39 provided on the lever 32 forcibly rotates the link 41 of the toggle link 4 in the reverse direction until the dead point is exceeded. For this purpose, the movable pulley 2 and the toggle link 4 are springs.
It returns with the projecting motion of both pressure contact bodies 11, 12 by 15, 15. Incidentally, the stopper 38 also comes into contact with the lever 32, and therefore the allowable rotation angle of the lever 32 is small, but if the dead angle of the toggle link 4 is exceeded, as described above, The subsequent returning operation is performed by the force of the springs 15, 15 applied to the movable pulley 2 via the wire 13. As the moving mechanism 3, here is shown the one using the toggle link 4 which can easily hold the state in which both the pressure contact bodies 11 and 12 are pulled in and can be simply operated. The structure is not limited to the moving mechanism 3 as long as the movable pulley 2 having the wire 13 connecting both ends to the pressure contact bodies 11 and 12 can be moved to apply tension to the wire 13. .
