[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An operating body control device for controlling the operating speed or the start of operation of an operating body according to the present invention will now be described with reference to an operating body control device 1 of a first embodiment shown in FIG. An example of the operating body control device 2 has a common basic configuration. The main circuit A includes a cylinder 3 having a required inner diameter. The main circuit A communicates with both ends of the cylinder 3 and the flow passage can be expanded and contracted in the middle. And a sub-circuit B composed of a pipe 4 having a control part C, and a piston rod 6 inserted from one other end is connected to a piston valve 5 fitted into the cylinder 3 of the main circuit A. The difference is that the operating body control device 1 of the first embodiment shown in FIG. 1 opens the piston valve 5 when the piston rod 6 is pulled, and communicates with the inside of the cylinder 3. When the piston rod 6 is pushed, the piston valve 5 is closed and the inside of the cylinder 3 is cut off. The working body control device 2 of the second embodiment shown in FIG. 5 is closed to shut off the inside of the cylinder 3, and on the contrary, when the piston rod 6 is pulled, the piston valve 5 is opened to communicate with the inside of the cylinder 3.

Next, the operating body control device 1 of the first embodiment shown in FIG. 1 will be described. One end 3a of the cylinder 3 of the main circuit A is closed by a cover plate 7, and the other end 3b of the cylinder 3 is A piston inserted through the bearing cover plate 9 into a piston valve 5 inserted into the cylinder 3 is closed by a bearing cover plate 9 in which a bearing hole 8 through which the piston rod 6 is slidably and slidably inserted is inserted. When the inner end of the rod 6 is connected and the piston rod 6 is pulled from outside the cylinder 3 and moves, the piston valve 5
The piston valve main body 5a integrally connected to the piston rod 6 moves to separate from the airtight connection surface 5b1 of the piston valve movable body 5b, and the piston valve movable body 5b is formed by the through hole 10 penetrating through the piston valve movable body 5b. The piston valve movable body 5b is supported by the lock screw portion 11 at the tip of the piston rod 6 without pushing out the gas in the cylinder 3 in the moving direction. When the piston rod 6 moves by receiving the pushing force from the outside in the opposite direction, the piston rod body 5a comes into contact with the airtight connecting surface 5b1 of the piston valve movable body 5b at which the piston rod 6 stops. The piston valve body 5a closes the through hole 10 and pushes out the cylinder 3 in the pushing direction. It is provided so as to move extruding direction side of the gas. Since the cylinder 3 of the main circuit A is in communication with the pipe 4 of the sub-circuit B, the amount of gas pushed out to the sub-circuit B is regulated by the control unit C. The moving speed of the piston rod 6 connected thereto can be controlled.

The control section C moves the screw valve 12a forward and backward by a screw screw 12 with a handle, expands and contracts the gap between the screw valve 12a and the corresponding casing 12b, and changes the flow sectional area.

With regard to the operating body control device 2 of the second embodiment shown in FIG. 2, when the piston rod 6 is pushed,
The piston valve main body 5a moves integrally with the piston rod 6 with respect to the piston valve movable body 5b, separates from the airtight connection surface 5b1 of the piston valve movable body 5b, and the piston valve main body 5a opens the through hole 10. On the contrary, when the piston rod 6 is pulled and comes into contact with the airtight connection surface 5b1 of the piston valve movable body 5b, the piston valve body 5a
Closes the through hole 10.

Next, FIG. 5 shows an example in which the operating body control device 1 of the first embodiment is applied to a self-closing sliding door 13.
Referring to FIG. 6, the self-closing sliding door 13 is provided such that the suspension rollers 14, 14 provided on the upper part are suspended on the inclined rail 15, and are automatically closed by gravity. The cylinder 3 is mounted on the upper part of the self-closing sliding door 13, and the outer end of the piston rod 6 is mounted on the vertical opening frame 16.

Therefore, when the self-closing sliding door 13 is opened manually against the action of gravity, the outer end of the piston rod 6 is fixed to the opening vertical frame 16 as described above. Since the cylinder 3 moves in the opening direction of the arrow in FIG. 1, the piston valve movable body 5b also moves, and the through-hole 10 closed away from the piston valve body 5a is closed.
To release. When the piston valve 5b moves further, the piston valve movable body 5b hits the lock screw portion 11 and is stopped and stopped, and the state where the through hole 10 is opened is maintained. Therefore, since the gas flow in the cylinder 3 is free, the cylinder 3 can move without being subjected to resistance by the piston valve 5, and the self-closing sliding door 13 can be easily opened manually.

Next, when the opening operation force of the self-closing sliding door 13 is lost, the self-closing sliding door 13 immediately moves in the closing direction since the closing action is exerted by the gravity action. The cylinder 3 moves together with the self-closing sliding door 13, moves the piston valve movable body 5b, and contacts the airtight connection surface 5b1 of the piston valve body 5a.
Since the through hole 10 of b is closed and gas does not flow,
The gas in the cylinder between the piston valve 5 and the cover plate 7 is pushed out through the control section C, and the cylinder 3
Is fed between the bearing cover plate 9 and the piston valve body 5a, so that the self-closing operation is adjusted to a constant speed. Therefore, if the self-closing sliding door 13 is, for example, a fire door for an emergency evacuation passage such as a tunnel, it can be opened at a stretch when it is opened, but when it is closed, it slowly closes. You can evacuate one after another.

Next, a description will be given of an application example in which the operating body control device 2 of the second embodiment is applied to a self-closing revolving door 18 pivotally supported by a hinge 17 with reference to FIGS. One end of an interlocking rod 20 is pivotally supported on a supporting shaft 19 erected at an appropriate position from a hinge 17 on the upper edge thereof, and the opposite end of the interlocking rod 20 is connected to the tip of the piston rod 6 pulled out of the operating body control device 2. An extension spring 23 is interposed between the interlocking shaft 21 and the left vertical frame 22 to which the hinge 17 is attached, and an operating body control is performed via the interlocking rod 20 by the extension action of the extension spring 23. The device 2 is actuated so as to always self-close at a constant slow speed.

That is, the self-closing revolving door 18 is in the closed state.
When the is opened, the interlocking rod 20 pivots with one end connected to the support shaft 19 and the other end to the interlocking shaft 21 in accordance with the rotation angle, and the interlocking rod 20 compresses the expansion spring 23 to press and move the piston rod 6. I do. In the compression movement of the piston rod 6, since the piston valve 5 is opened, there is no resistance to the movement of the piston valve 5, so that the self-closing revolving door 18 can be opened smoothly. Next, when the operating force for opening the self-closing revolving door 18 disappears, the compressed expansion spring 23
To transmit the expanding force to the interlocking rod 20 and push the piston rod 6, so that the piston valve 5 is connected to the connecting airtight surface 5b1 of the piston valve movable body 5b, and the through-hole 10 is formed. It closes and moves the gas in the cylinder 3 through the control part C, so that it can be adjusted slowly, and the self-closing revolving door 18 slowly moves.
Can be activated to close.

Next, the delay operation device 24 of the first embodiment for controlling the start of operation using the operation device control device 1 of the first embodiment will be described with reference to FIGS. 9, 10 and 11. An automatic closing type sliding door 27 which is entirely suspended by contacting rollers 26, 26 with the inclined rail 25 is provided, an opening handle 28 is provided on the automatic closing type sliding door 27, and a rotating portion 28a thereof is provided.
Connecting lever 29a which is driven by connecting roller 29a1 to
The self-closing sliding door 27 is provided with a driven operation rod 29 having an operation section 29 b and a balancer section 29 c by a support shaft 30.

The operating body control device 1 is mounted vertically behind the automatic closing type sliding door 27, and a linking portion 31 is mounted at a suitable intermediate position between the end of the piston rod 6 protruding from one end of the cylinder 3 and this linking. The operating portion tip 29b1 of the driven operating rod 29 faces the portion 31 and the opening handle 2
The operation unit 29b is rotated in accordance with the opening operation of the operation unit 8, and the linking unit 31 is linked and moved by the operation unit tip 29b1, so that the piston rod 6 is pulled up from the cylinder 3.

Since the gravitational actuator 32 is slidably fitted between the linkage 31 and the tip of the piston rod 6, the gravitational actuator 32 is connected to the linkage 31 from above, and As the piston 31 moves, it moves upward together with the piston rod 6 and pushes back the engaging claw 33 before reaching the upper limit position of the operating portion tip 29b1, and the operating portion tip 29b1 opens and the handle 28 returns to the initial position. When it returns to the position, it descends by the action of gravity and engages with the engaging claw 33, and its raised position is held.

The engaging claw 33 has its base end rotatably supported on a support shaft 35 provided on a support 34, and has an arc-shaped long hole 36 centered on the support shaft 35 with a required width formed in the upper part. A support shaft 37 fixed to the support 34 is fitted, and when the gravity type actuator 32 passes by the side of the engagement claw 33, it turns to allow the passage, and after passing, it moves up and down by gravity. It is provided so that it automatically returns into the passage, and the arc-shaped long hole 36 hits the support shaft 37 to prevent further rotation and stops at a required position.

The support 34 is provided with the automatic closing type sliding door 2.
7, while being rotatably supported about a support shaft 38 fixed on the support shaft 7, and opening an arc-shaped long hole 39 around the support shaft 38;
A support shaft 40 fixed on the self-closing sliding door 27 is fitted into the arc-shaped long hole 39, and the support shaft 38 is engaged with the engagement claw 33.
A balancer 42 is suspended by providing a support shaft 41 on the opposite side to the above. The weight of the balancer 42 is made larger than that of the gravity-type actuator 32 so that the gravity-type actuator 32 engaged with the engagement claw 33 can be supported. At the tip of the piston rod 6, a pressing actuator 43 is provided integrally.

A ratchet gear 44 is integrally provided on the side of the roller 26 disposed behind the self-closing type sliding door 27, and a ratchet 45 is made to face the ratchet gear 44, and a base end of the ratchet 45 is supported by a support shaft 46. At the same time, a balancer portion 47 is integrally provided on the opposite side with respect to the support shaft 46, and an interlocking rod 48 is connected and suspended from the tip of the ratchet 45 to balance the whole, and the ratchet 45 always has the ratchet gear 4
A spring 49 is attached to the tip end of the ratchet 45 so as to
And the collision linking portion 50 formed by bending the lower end of the interlocking rod 48 is made to face the descending passage of the gravity type actuator 32.

Since the delay operation device 24 is constructed as described above, when the opening handle 28 is pulled, the rollers 26, 26
When the ratchet gear 44 rotates in the opening direction, the ratchet gear 44 simultaneously rotates. However, in the rotating direction, the ratchet 45 is pushed out, so that the ratchet 45 does not engage and can freely rotate. Therefore, it can rotate on the inclined rail 25 to move smoothly and open. Then, when the hand is separated from the opening handle 28, the automatic closing type sliding door 27 is operated by gravity.
When the user attempts to move in the closing direction, the ratchet 45 engages with the ratchet gear 44 by its urging force and prevents its rotation, so that the stop, that is, the automatic closing type sliding door 27 is kept open. .

Pulling the opening handle 28 and automatically closing the sliding door 27
When the opening is opened, the driven operating rod 29 is rotated in accordance with the operation of the opening handle 28, and the distal end 29b1 of the operating portion is connected to the link portion 3.
1 is pushed up to pull up the piston rod 6 from the cylinder 3. Since the piston rod 6 opens the piston valve 5 as described above, the piston rod 6 can be easily pulled up without receiving resistance. Then, the gravitational type operator 32 supported by the linking portion 31 is raised together with the piston rod 6, and the gravitational type operator 32 pushes away the ratchet 45 and passes laterally.

The ratchet 45 returns part of the ratchet 45 back into the passage of the gravity type actuator 32 due to its gravitational action. Since the tip 29b1 rotates to the original position,
The piston rod 6, the piston valve 5, the pressing actuator 43 at the upper end, etc., descend into the cylinder 3 by the total weight, and the downward movement is caused by the piston valve 5 being closed for the above-mentioned reason. Since the gas in the cylinder 3 is returned to the cylinder 3 again through the control section C, the descending movement speed can be controlled.

When the pressing actuator 42 at the upper end comes into contact with the gravitational actuator 32 due to the lowering of the piston rod 6, gravity including the piston rod 6 is applied, so that the support force of the engaging claw 33 of the balancer 42 is exceeded. , The support 34 is rotated about the support shaft 38 together with the engaging claw 33 to pass through the gravity type actuator 32. The gravity type actuator 32 having passed through the engagement claw 33 is free and descends at a stretch with the piston rod 6 as a guide, collides with the collision linking unit 50, releases the stored energy, lowers the ratchet 45, and lowers the ratchet gear. 44 is opened. Then, the roller 26 with the ratchet gear rotates freely, and the self-closing sliding door 27, which has been latched up to that time, is caused to self-close by the inclined rail 25. Therefore, the automatic closing type sliding door 27 can be automatically closed after a predetermined time.

Next, a delay actuating device 51 according to a second embodiment for controlling the start of the actuation using the actuating body control device 1 according to the first embodiment will be described with reference to FIGS. 12, 13 and 14. Then, first, in the operating body control device 1, the control C section of the sub-circuit B configured for the main circuit A connects the flow rate control valve section 52, and dials the dial 52a in the display direction (the minus direction is the final stop). (Close at the point, open in the + direction, fully open at the final point) to adjust the amount of liquid flowing to the required amount. A mechanical opening / closing valve portion 53 is connected to the middle of the pipe 4 of the sub circuit B, and an opening / closing lever 53a is provided.
With this operation, the operator 53b appears and disappears, and the internal on-off valve (not shown) is opened and closed (fully opened or closed).

In the embodiment, the flow control valve section 52 and the mechanical opening / closing valve section 53 are arranged, for example, in the self-closing sliding door 13 shown in FIG. Further, as shown in FIG. 13, a rotation adjuster 54 is attached to the self-closing sliding door 13, and an operation cam 54b and a linkage gear 54c are provided on a rotation shaft 54a thereof. The mechanical opening / closing valve 53 is connected to the opening / closing lever 53a of the mechanical opening / closing valve 53, and the mechanical cam 54b is operated to operate the mechanical opening / closing valve 53.

A support shaft 55 is disposed adjacent to the rotation adjuster 54, and an operation lever 56a provided integrally with the support shaft 55 is provided on the support shaft 55.
And the drive gear 56b are rotatably provided.

A support shaft 58 is provided on a support portion 57 fixed to a frame or wall for supporting the self-closing sliding door 13, and the support shaft 58 is provided.
A stopper 60 that is rotatably supported on one side and is rotatable on one side, and that stops rotation by a detent 59 on the other side is provided.

The operation cam 54b is formed to have a large required width on the base end side, and is provided with an opening operation portion 54b1. When the opening / closing lever 53a rides on the opening operation portion 54b1, the mechanical opening / closing valve portion 53 is opened. It is provided as follows.

As shown in FIG. 13, when the self-closing sliding door 13 is moved to the open side (arrow side), the operation lever 56a
Of the operating lever 56
is rotated about the support shaft 55, and the rotation is transmitted from the driving gear 56b to the linkage gear 54c to rotate the rotation adjuster 54c.
Is rotated, and the operation cam 54b is rotated half a turn. Then, when the operation cam 54b rotates, the mechanical opening / closing valve 5 moves from the opening operation section 54b1 on the proximal end side.
3 is closed. Further, when the self-closing sliding door 13 is further moved to the opening side and the tip of the operating lever 56a is disengaged from the stopper 60, the operating lever 56a becomes free and opens the rotating shaft 54a. According to the function of the internal structure of the rotation adjuster 54, the operation cam 54b is returned by performing return rotation at a required speed.

The self-closing sliding door 13 may be further moved to the open side to open the self-closing sliding door 13 widely, and in this case, the stopper is used to restore the opening stop time of the self-closing sliding door 13. The self-closing sliding door 1

A support shaft 58a is provided on the support shaft 7a. The support shaft 58a is rotatably supported on the support shaft 58a.
May be deployed and stopped.

The self-closing sliding door 13 maintains the open state,
Although the evacuation route is secured, when the tip of the operation lever 56a is disengaged from the stopper 60, the rotating shaft 54a is opened, and the rotating shaft 54a returns at a required speed according to the function of the internal structure of the rotation adjuster 54 to rotate. After returning the operation cam 54b,
The opening lever 53a of the mechanical opening / closing valve section 53 rides on the opening operation section 54b1 of the operation cam 54b, and again,
The mechanical opening / closing valve 53 is opened. Therefore, the self-closing sliding door 13 is automatically closed at a constant speed.

When the operation lever 56a rises and collides with the stopper 60a and the stopper 60 when the self-closing sliding door 13 returns, the stopper 60a and the stopper 60 are rotatable in the closing movement direction. Therefore, it can rotate freely in the moving direction and pass freely.
Therefore, at the time of emergency evacuation, for example, the self-closing sliding door 13 is opened manually to maintain the open state for about 30 seconds to one and a half minutes, and then returns at a speed of 80 cm for one minute.
3 is to close the open passage formed by the valve 3.
