Description

[Detailed description of the invention] (Field of industrial application) This invention has a plurality of movable partition panels that are movably suspended along rails laid on the ceiling. The side edges of the panels are brought into contact with each other, and the upper and lower edges are semi-automatically fixed to the ceiling and floor by arranging them, and when removing each panel, the fixing of the panels is released in sequence starting from the last panel. This invention relates to a fixing device for a movable partition panel that can be stored in a proper location.

(Conventional technology) Movable partition panel (hereinafter simply referred to as panel)
For example, as a fixing device for
Various methods have been proposed, as disclosed in Japanese Patent Publication No. 54-43960.

(Problem to be solved by the present invention) However, in the conventional device, the outer end of the horizontal lever protruding from the side of the panel is raised and lowered, or the tip of the handle is inserted from the side and rotated. Since each panel has to be fixed or unfixed, the operation is time-consuming and troublesome when there are a large number of panels.

In addition, when using a handle, it was necessary to store the removed handle so that it would not be lost.

(Means for Solving the Problem) The present invention provides pressure contact rods that can be raised and lowered by a motor that can be rotated in both forward and reverse directions at the upper and lower ends of a plurality of movable partition panels suspended from rails, and that are connected to the wall surface. A pair of feeding and receiving electrodes are provided on the side end surfaces of each panel, which contact each other when they come into contact to supply power to each motor, and between the receiving electrode and the motor are the upper and lower limits of the pressure contact rod that moves up and down. A normally closed limit switch that regulates the power supply, and a normally closed micro switch that is operated by the side end face of the adjacent panel on the opposite end of the panel from the wall, and a motor power switch on the wall. The above-mentioned problem is solved by providing a switch for changing the direction of rotation of the motor.

(Function) In the device of the present invention, when the power switch is closed, the changeover switch is set as the fixed side, and the side edges of the panel and the wall surface are brought into contact with each other, and the side edges of the panels are arranged in order, each corresponding electrode will come into contact. In addition, since the micro switch for detecting adjacent panels on the end panel is always closed, the motor in the panel is energized, and after the upper and lower pressure contact rods are in pressure contact with the ceiling and floor, respectively, via the reducer, the upper limit is reached. A limit switch automatically stops the motor and secures this panel.

A panel that is fixed at one end will not loosen due to the frictional resistance of the speed reducer even if the power supply to the motor is cut off.

In addition, for each panel fixed as described above, if you close the power switch and set the changeover switch to the release side, each member will operate in the opposite direction to when it was fixed, and the fixation will be released in order starting from the end panel. .

(Example) Fig. 1 schematically shows a partition to which the present invention is applied, in which 1 is an intermediate panel, 2 is an end panel, 3 is a wall, and 4 is a column attached to the wall. , 5 is a control section embedded in the wall body 3.

A protruding strip 6 and a groove 7 are formed on the left side of both panels 1 and 2, and on the right side of both panels 1 and 2 and the column body 4, respectively. Three pairs of receiving electrodes 8 and feeding electrodes 9 are attached.

A normally closed adjacent panel detection micro switch 10 operated by opposing protrusions 6 is attached to the groove 7 of the panel 1.

As shown in FIGS. 2 to 4, the intermediate panel 1
The guide groove 11 formed on the upper end surface has a guide groove 11
A pressing rod 12 of equal length is fitted, and a lifting rod 13 facing downward is fixed to the center thereof.

The lower part of the elevating rod 13 is fitted into the upper part of the elevating tube 14, and has a vertically elongated hole 15 bored in the lower part of the elevating rod 13.
is engaged with a pin 16 provided through the upper part of the elevating cylinder 14.

The lifting rod 13 has a flange 17 provided on its upper part.
It is biased upward by a coiled compression spring 18 wound between the upper ends of the elevating tube 14.

The elevator cylinder 14 is equipped with a decelerator 19 provided within the panel 1.
It is raised and lowered by a motor 20 that can rotate in both directions.

At the center of the elevator tube 14, there is a drive plate 2 facing both sides.
1 is fixed, and a normally closed upper limit switch 22 and lower limit switch 23, which are operated by a drive plate 21, are installed above and below it, respectively.

The above is the configuration of the upper half of the intermediate panel 1, but the lower half is also configured vertically and horizontally symmetrically with the above, and the end panel 2 has a configuration in which the feeding electrode 9 is omitted from the intermediate panel 1.

Figure 5 shows the electrical wiring of this device.
4 and 25 are a power switch and a motor 2, respectively.
The switch 26 is a power source for changing the direction of rotation of the 0, and the figure shows that the wall 3 and the panels 1 and 2 are separated, and the pressure rod 12 enters the guide groove 11.
The panels 1 and 2 are shown in a freely movable state and the power switch 24 is open.

In this state, move each panel 1,
When the concave grooves 7 of the wall body 3 and the protrusions 6 of the panel 1 are brought into contact with each other, the corresponding feeding electrodes 9 and receiving electrodes 8 are brought into contact.

Also, since the micro switch 10 is closed, if the power switch 24 is closed, each panel 1,
The motor 20 of No. 2 starts, and both the upper and lower pressure contact rods 12
The panels project from the guide groove 11 towards the ceiling 27 and the floor 28, and are pressed against each other by the bias of the spring 18. Then, the drive plate 21 opens the limit switch 22, stops the motor 20, and each panel 1 Fixed.

Close the power switch 24 in advance, and then close the wall 3.
The panel 1 can be fixed in the same manner as described above even if the concave grooves 7 of the panel 1 are brought into contact with the protrusions 6 of the panel 1.

Similarly, panel 2 can be continuously fixed to panel 1 by moving the panel 1 and bringing the side end surfaces into contact with each other, and at this time, panel 1
The micro switch 10 opens.

Each panel 1, 2 fixed in this way is
Even when the power switch 24 is opened, the frictional resistance of the speed reducer 19 prevents the fixation from loosening and moving.

Each fixed panel 1, 2 has a power switch 2
4 and switch the selector switch 25 to the release side, the lower limit switch 2 of all panels 1 and 2
3 is closed, the end panel 2 where the micro switch is closed will cause the motor 20 to reverse and
The pressure rod 12 enters the guide groove 11, and then the drive plate 21 opens the lower limit switch 23 to stop the motor 20 and release each panel 2.

When the panel 2 is moved, the micro switch 10 of the next panel 1 is closed, and this panel 1 is also released in the same manner as described above.

All panels 1 and 2 fixed in this way are
By operating the switches 24 and 25 once, the panels 2 at the end can be sequentially released.

Note that there is no practical problem even if the terminal panel 2 is also provided with the feed electrode 9 and the micro switch 10 and has the same configuration as the intermediate panel 1.

(Effects of the present invention) According to the device of the present invention, when partitioning a room with a large number of panels or when removing the panels, one
After operating the switch twice, it is sufficient to simply move the panel, making the operation extremely simple and the work can be done in a short time.

Moreover, when partitioning a room, unlike conventional devices, the panels in the middle were incorrectly butted against each other incompletely, and each panel was fixed with a gap left.
There is no possibility of having to redo the fixing operation for each subsequent panel.
