Description

[Detailed description of the invention] 【Technical field】

The present invention relates to a press-contacting device that enhances the sound insulation effect by press-contacting press-contact bodies provided above and below a panel to a ceiling surface and a floor surface in a movable partition.

[Background technology]

As shown in FIG. 4 and FIG. Pressing body 11.1 that can freely slide up and down arranged in
2 are urged upward and downward by springs 15, respectively,
As shown in FIG. 5, pressure contact bodies 11 and 12 protruding from the upper and lower surfaces of the panel 1 are pressed against the ceiling surface (rail 10) and the floor surface. To release the pressure contact when moving the panel 1, the pressure contact bodies 11 and 12 are respectively drawn into the panel 1 against the bias of the spring 15. Here, in order to be able to pull the pressure contact bodies 11 and 12 arranged above and below the panel 1 into the panel 1 in a single operation, for example, as shown in FIG. A pair of racks 18 and 18 connected to the press-contact bodies 11 and 12 via wires 13 and the like are engaged with a pinion 17 equipped with a reverse rotation prevention function to release the reverse rotation prevention function. Pressure contact body 11,
12 is projected, and by rotating the pinion 17 with the lever 16, both the side pressure contact bodies 11 and 12 are drawn into the panel 1. In the figure, 20 is a push button for releasing the reverse stop. However, in conventional structures including the above structure, the side pressure contact bodies 11 and 12 can only be moved the same distance apart, so the dimensions of the gaps that end up being closed by the pressure contact bodies 11 and 12 are the same. There is a restriction that it must be.

[Purpose of the invention]

The present invention has been made in view of these points, and its purpose is to ensure that even if the dimensions of the gap on the ceiling side and the gap on the floor side are different, the gaps can be reliably blocked. The purpose of the present invention is to provide a pressure welding device for movable partitions.

[Disclosure of the invention]

Accordingly, the present invention provides a pressure welding device for a movable partition in which pressure welding bodies that are vertically slidable are disposed above and below a partition panel, and each pressure welding body is biased by a spring in the direction of protrusion from the panel. A wire whose other end is connected to one press-fitting body, a movable pulley on which the middle of the wire is hung, and a moving mechanism that moves the movable pulley to apply tension to the wire. By moving the movable pulley and applying tension to the wire, the side pressure contact body, which is spring-biased in the direction of protrusion from the panel, is pulled into the panel. In this case, because one end of the wire is connected to one insulation displacement body and the other end is connected to the other insulation displacement body, even if the dimensions of the gaps closed by the side insulation displacement bodies are different, the gap is The amount of movement of the pressing member on the larger side automatically becomes larger than the amount of movement of the other pressing member. The present invention will be described in detail below based on the illustrated embodiments.
The figure shows the basic form of the present invention, in which press-contact bodies are disposed at the upper and lower ends of a panel 1 so as to be able to slide up and down, respectively, and are both biased in the direction of protrusion from the panel 1 by springs 15, 15. 11 and 12, connect each end of one wire 13 to connect the side pressure contact bodies 11 and 12 with the wire 13, and in the middle of this wire 13 there is a movable wire that is movable in the width direction of the panel 1. By engaging the pulley 2 and moving the movable boolean 2, the upper and lower side pressure contact bodies 1 are
1.12 are moved in opposite directions at the same time. In the figure, reference numeral 22 indicates an idle pulley disposed near each pressure contact body 11, 12, and reference numeral 21 indicates a pair of idle boobies 9- disposed near the movable pulley 2, and the idle pulley 21 to which these wires 13 are hung. .22 is panel 1
is fixed. Mobile machine IfI for moving the above movable boo 1 and 2
An example of I3 is shown in FIGS. 2 and 3. This moving mechanism 3 embedded in the side end surface of the panel 1 rotatably supports the pair of idle pulleys 21, 21 mentioned above by shafts 35, 35, and also includes a frame 30 fixed to the panel 1, and a frame 30 fixed to the panel 1. 30, a pair of levers 31, 32 rotatably supported by a shaft 36, and two links 41, 42 connected by a shaft 43, -
The movable boot I-no 2 is inserted into the other end of the toggle link 4, and slides inside the elongated hole 34 formed in the frame 30. It is supported by a movable pongee 33. In the figure, reference numeral 37 denotes a drop-off prevention pin provided on the toggle link 4 and the V7 frame 30 in order to prevent the wire 13 from coming off from the movable boot 9-2 and the idler pulley 21.21. Therefore, when both the side pressure contact bodies 11 and 12 protrude from the panel 1 and are in pressure contact with the ceiling surface and the floor surface, respectively, the movable pulley 2 is in the position shown by the solid line in Figure tjIJ2,
The trouble ring 24 is in a bent state. Also, both levers 31, 321! It is located along the side edge surface of the panel 1. To release this pressed state, the lever 31 may be pulled out and rotated. As the lever 31 rotates, the toggle link 4 causes the link 41 to move to the lever 31.
This causes the shaft 33 disposed at the movable end of the toggle link 4 to move along the elongated hole 34. In other words, the movable pulley 2 moves and the surface pressure contact members 11 and 1 are connected via the wire 13.
2 in the direction of drawing it into the panel 1, and the pongee 43 connecting the two links 41 and 42 of the toggle link 4 crosses the line connecting the shafts 36 and 33,
Once the link 42 comes into contact with the stopper 38 provided on the frame 30, the toggle link 4 is held in the state shown by the chain line in FIG. 2 even if the lever 31 is returned to its original position. The surface pressure contact members 11 and 12 are both held in a state drawn into the panel 1. Even if the dimensions of the gap between the ceiling side and the cost price where the surface pressure contact bodies 11 and 12 close are different, in the drawing process of the surface pressure contact bodies 11 and 12, the pressure contact body 11. This simply causes the wire 13 on the 12 side to be sent to the pressure welding body 12.11, which has a smaller gap size, and the surface pressure welding bodies 11.12 are both pulled into the panel 1 and the pressure welding is released. . Moreover, even if only one of the pressure contact bodies 11.12 is drawn in first, the other pressure contact body 12.11 will also be completely drawn in eventually. In order to return the toggle link 4, which has been held in the state shown by the chain line in the figure because it has passed the dead center, to the position shown by the solid line again and perform pressure contact, the lever 32 may be rotated. Lever 3
If you pull out the lever 32 and rotate it, the lever 32
The engaging pin 39 provided in the toggle link 4 forcibly rotates the link 41 in the opposite direction until it passes the dead center. For this purpose, the movable pulley 2 and the toggle link 4 return as the springs 15 and 15 cause the surface pressure contact bodies 11 and 12 to project. Note that the stopper 38 also comes into contact with the lever 32, and for this reason, the permissible rotation angle of the lever 32 is small, but if the toggle link 4 is moved beyond its dead center, as described above, The subsequent return operation is performed by the force of the spring 15.15 applied to the movable pulley 2 via the wire 13. Here, as the moving mechanism 3, a toggle link 4 is shown which makes it easy to maintain the surface pressure contact bodies 11 and 12 in the retracted state and also makes the operation itself simple. The structure is not limited to the above-mentioned moving mechanism 3, as long as it has a structure that can apply tension to the wire 13 by moving the movable pulley 2 on which the wire 13, which is connected at both ends to the pressure-welding bodies 11 and 12, is hung. .

【Effect of the invention】

As described above, in the present invention, a wire is provided whose one end is connected to one press-fitting body and the other end is connected to the other press-fitting body, and a movable pulley on which the middle of this wire is hung is moved. By applying tension to the wire, the surface pressure welding bodies, which are spring-biased in the direction of protrusion from the panel, are pulled into the panel, so the dimensions of the gaps that each surface pressure welding body closes are different. Even if
It should be possible to press-fit and release the press-fit without any problems, and the wire that will be passed through the panel is connected to a press-fitting body with at least one side exposed to the outside, and a movable pulley is used inside the panel. It is easy to wire and adjust the length of the wire because it only needs to be hung on the wire and there is no need to connect it to other parts.
