[Detailed description of the invention] This invention is a door that opens and closes by sliding but can also be opened and closed by swinging if necessary, and when the door that was opened by swinging is closed again, This invention relates to a door opening/closing device that sets a steady rest in conjunction with the closing operation.

The applicant has already proposed a door that can be opened and closed both by sliding and by swinging, as shown in FIGS. 1 to 3. this is,
A hanging frame 4 is suspended from an upper rail 2 of a blind 1 via pulleys 3, 3, and a door 5 is further suspended from this hanging frame 4. By the forward and reverse rotation of the drive device 6, the left and right doors 5, 5 are rotated through the belts 7, 7 and pulleys 8, 8, as shown in FIG.
Open and close by sliding along.

Here, when a larger opening than the door 5 is required, such as when bringing in large luggage or when an abnormal situation such as a fire occurs, the third door
As shown in the figure, when the door 5 is pushed outward, the door 5
The engaging parts 14, 14 with the suspension frame 4 are disengaged and swing around the swing fulcrum parts 10, 10, and the sliding door 9 is also pushed out by the swing of the door 5, and the upper and lower swing fulcrum parts 11, Swing around 11, 12, 12. Even if doors 5 and 5 remain open, pillars 1 on both sides
Slide to position 3, 13, giving you twice the normal width.

However, in such a door that can be opened and closed by both sliding and swinging,
When a door that has been opened by swinging is returned to its sliding state, a steady rest is automatically installed to ensure that the sliding door opens and closes smoothly and does not rattle due to wind pressure, etc. It is necessary to make it stand out.

The present invention has been developed to achieve the above-mentioned purpose, and consists of a drive cam that is linked to the swinging opening and closing operations of the door, and a steady rest that moves forward and backward from the door, connected by a connecting means such as a wire. It is.
With this structure, the steady rest is automatically set when the door is closed, and the structure is simple and operates reliably.

Hereinafter, one embodiment of the present invention will be described based on the drawings from FIG. 4 onwards.

In Figures 4 to 8, 4 is a hanging frame, 15
16 is the upper stile of the door 5, 17 is the lower stile of the door 5, and 18 is the plate glass of the door 5.

An L-shaped latch fitting 19 is fixed to the lower surface of one end of the hanging frame 4 with a gap therebetween, and an F-shaped engagement plate 20 is fixed to the inside of the upper frame 16 facing the latch fitting 19. A ball 23 is urged upwardly by a spring 22 from below into the insertion groove 21 of the engagement plate 20, and these latch fittings 19 and the engagement plate 20
The engaging portion 14 is constituted by the above. At the tip of the latch fitting 19, as shown in FIG. 4a,
An integrally protruding contact member 24 is provided.

A drive cam 25 is provided at the upper end of the stile 15. As shown in FIG. 9, this drive cam 25 has a main body 26 that is rotatable around a vertical shaft 27, and a claw piece 29 is provided at the tip of the drive cam 25 so as to be rotatable by a pin 28. The claw piece 29 is constantly attracted by the spring 30. When the claw piece 29 comes into contact with the contact member 24 from the left side in the figure,
Only the claw piece 29 rotates against the spring 30 and the main body 26 does not rotate, and when the claw piece 29 contacts the contact member 24 from the right side in the figure, it stops at the stopper 31 of the main body 26. It is designed so that it can be rotated together with the main body 26. A distal end portion 34 of a dogleg-shaped cam 33 provided at the upper end of the stile 15 is engaged with the base end portion 32 of the drive cam 25 . This cam 33 is rotatably provided by a horizontal shaft 35 of the stile 15, and a wire 36 serving as a connecting means is connected to the other end of this cam 33. The other end of the wire 36 is connected to a ratchet 38 provided within the stile 15 and constituting a steady rest holding means 37. This ratchet 38 is rotatably provided on a horizontal shaft 39 in the frame 15, and the wire 36 is attached to the ratchet 38.
A spring 40 is provided at a position having a phase difference of approximately 180 degrees from the connecting portion, and is further connected with wires 41 and 42 as connecting means. There is. The lower end of one of the wires 41 is fixed to a shaft-shaped steady rest 43, and the other wire 42 is connected to an unlocking body 59, which will be described later. This steady rest 43 is the catch seat 4
A coil spring 47 is interposed between a spring receiver 46 which penetrates between 4 and 45 from below and is fixed to this steady rest 43 and the upper receiving seat 44 to constantly urge the steady rest 43 downward. There is. Further, a door wheel 49 is provided at the lower end of the steady rest 43 and is loosely fitted into the groove-shaped lower rail 48, and when the door wheel 49 is sucked upward and stops on the lower surface of the lower seat 45,
It is designed to approximately coincide with the lower surface of the lower stile 17.

A touch part 50 as an opening operation part is provided facing the ratchet 38 and located on the indoor side in the middle of the stile 15. The upper end of the arm 51, which is integral with the touch portion 50, is rotatably provided around a horizontal shaft 52 within the frame 15 as a fulcrum.
This arm 51 also has a return spring 5 at its tip.
3, and the ratchet claw 54, which is integral with the arm 51, is in constant contact with the outer periphery of the ratchet 38. In addition, on the outer periphery of the ratchet 38,
A notch 55 that engages and disengages from the ratchet pawl 54 is formed.

Next, in the frame 15 there is a so-called Gremon tablet 5.
6 is provided. This Gremont lock 56 has an internal slider that moves up and down using a knob 57 on the indoor side and a key 58 on the outdoor side, and an unlocking body 59 connected to the slider and protruding above the lock 56 and a lower lock pin. 60
is raised and lowered. That is, when the lower lock pin 60 protrudes from below the lock 56, the bearing 6
1 and provided in the lower rail 48.
It is inserted into 2. Also, this lower lock pin 60
A wire 63 as a connecting means is connected upward, and a link 65 that rotates around a shaft 64 is connected to the upper end of the wire 63 as shown in FIG. A rod 67 urged downward by a leaf spring 66 is connected. This Rod 6
7 protrudes from a hole in a bearing 68 at the upper end of the stile 15, and its tip faces the lower end of an upper lock pin 70 provided in the suspension frame 4 and urged downward by a spring 69. is inserted into a hole in a lock plate 71 fixedly provided on the upper part of the hanging frame 4. A power switch 72 is provided on the top of the lock plate 71 to turn off the power to the automatic door when the door is locked.

In the above configuration, the driving cam 25, the steady rest holding means 37, the steady rest 43, the locking means consisting of the upper and lower locking pins 60, 70, etc., the opening operation section 50, the Gremon lock 56, the wires 36, 41 as the connecting means, 42, 63, etc. are made into a unit and are housed and attached within the frame 15 of the door 5.

Next, the operation of the opening/closing device according to the present invention will be explained. 4a, b, and c show the door 5 being opened by swinging. In this state,
The latch fitting 19 and the engagement plate 20 are not engaged.
Furthermore, the touch part 50 serving as the opening operation part is also pressed, and the ratchet pawl 54 is disengaged from the notch 55 of the ratchet 38.
8 is attracted by the spring 40 and rotates to the right as shown in FIG. 4b. Therefore, the wire 36 is attracted downward, and the wires 41 and 42 are attracted upward. As the wire 36 is sucked downward, the cam 33 is sucked and rotates to the left around the shaft 35, and the drive cam 2 engaged with the cam 33 is rotated to the left about the shaft 35.
5 is rotated to the right in the figure as shown in FIG. 4a. Since the wire 41 is attracted upward, the steady rest 43 at the lower end is also raised against the spring 47. At this time, since the wire 42 is also drawn upward at the same time, the unlocking body 59 of the lock 56
Therefore, the lower lock pin 60 interlocked with this unlocking body 59 also rises. When the lower lock pin 60 rises, the wire 63 becomes slack, so the rod 67 is lowered by the spring 66, and the upper lock pin 70 provided above the rod 67 is lowered by the spring 69.

Here, in order to return to sliding opening/closing, open the door 5.
When the pivoting fulcrum part 10 is used as a fulcrum and is pulled toward the hanging frame 4 by swinging, the state shown in FIG. 5 is obtained. Then, the engagement plate 20 of the engagement portion 14 and the latch fitting 19 engage with each other as shown by the chain line in FIG.
The driving cam 25 is rotated to the left in the drawing by contacting the claw piece 29 of No. 5. Claw piece 29 of this drive cam 25
The tip 34 of the cam 33 rotates to the right as shown in FIG. 5a until the cam 33 is removed from the contact member 24. Then, the wire 36 is pulled upward, and the ratchet 38 rotates to the left in the figure against the force of the spring 40. This rotation of the ratchet 38 in the left direction causes slack in the wire 41, so that the steady rest 43 is fixed to the spring 47.
descends by At this time, the lowering of the steady rest 43 and the groove of the lower rail 48 do not coincide in timing, and even if the door roller 49 contacts the floor, the steady rest 43
Since it is urged downward by the spring 47, it fits into the groove of the lower rail 48 at a position that corresponds to the groove. Also,
As the ratchet 38 rotates to the left in the figure, the notch 55 slightly exceeds the position of the ratchet pawl 54, creating a gap d. and drive cam 25
When the claw piece 29 comes off the contact member 24, the ratchet 38 tries to return to its original position by the spring 40 and rotates to the right, but when it returns by the gap d, it is stopped by the ratchet claw 54 and cannot return any further. There isn't. However, the drive cam 25 and cam 33 are connected to the ratchet 38.
With the return movement of the gap d, it returns to its original position as shown in Figures 6a and b. Incidentally, although the wire 42 connected to the unlocking body 59 also loosens, the lower locking pin 60 remains raised because no other force acts to lower the unlocking body 59, and therefore the upper locking pin 70
remains lowered, and both lock pins 60 and 70
The locking means consisting of is not locked.

Next, when closing and locking the door 5, if you lock it with the key 58 or the knob 57,
As shown in c, the lower lock pin 60 is lowered. At this time, since the wire 42 is slack, the unlocking body 59 also descends. When the lower lock pin 60 descends, it fits into the lock hole 62 of the lower rail 48,
At the same time, the wire 63 is pulled down against the spring 66, and the link 65 rotates to the left in the figure to connect the rod 6.
7 rises against the spring 66, and then the rod 67
The upper lock pin 70 is pushed up against the spring 69 and is locked by fitting into the hole of the lock plate 71, and the power switch 72 is turned off. At this time, the wire 42 connected to the unlocking body 59 has no slack, but it is not related to the operation of the steady rest 43.

Next, in an emergency, when the touch part 50 serving as the opening operation part is pushed against the spring 53 as shown in FIG. The notch 55 and the ratchet pawl 54 are disengaged, and the ratchet 38 is rotated to the right in the figure by the spring 40. Since the wire 36 is pulled down by the rotation of the ratchet 38, this wire 36
There will be no slack. Since the wires 41 and 42 are simultaneously pulled up, the steady rest 43 connected to one of the wires 41 rises against the spring 47 and escapes from the lower rail 48. As the unlocking body 59 connected to the other wire 42 rises, the lower lock pin 60, which is interlocked with the unlocking body 59 via a slider inside the lock, also rises and comes out of the lock hole 62, and
Since the wire 63 connected to the lower lock pin 60 becomes slack, the spring 66 tightens the rod 67.
As the link 65 descends, the link 65 rotates to the right in the figure, and the upper lock pin 70 also descends due to the force of the spring 69 and comes out of the hole in the lock plate 71.
Power switch 72 is turned on. When the door 5 is strongly pushed outside in this state, the door 5 is disengaged from the engagement part 14 and swings around the swing fulcrum part 10, resulting in the state shown in FIG. 4.

In the above embodiment, the touch part 50 as an opening operation part is formed of a rectangular touch plate and is attached to the stile 15, but the present invention is not limited to this. It may also be formed by a horizontal rod-shaped touch stick. Alternatively, it may be shaped like a small push button, usually covered with a thin transparent plate, and then broken and pushed in case of an emergency. Further, although the opening operation unit 50 is designed to work by pushing with the hand, it can also work by pulling, turning, pulling up, pulling down, etc., or by kicking, stepping on, or hitting with the body. You can do it like this.

Since the present invention is configured as described above, when the door that has been opened by swinging is closed again, the steady rest is automatically set via the connecting means in conjunction with the closing operation, and therefore, the steady rest is automatically set via the connecting means. The sliding door opens and closes smoothly, and the door does not rattle due to wind pressure or the like.

For doors that can be opened and closed by both swinging and sliding, when the steady rest is fitted to the lower rail, the drive cam will rotate in one direction and in the other. Since the steady rest and the drive cam must not always operate together, they may need to operate in conjunction with each other or independently of each other.

In the present invention, by using a wire as a connecting means, the above object can be achieved by pulling or loosening the wire.

Furthermore, since wires were used as the connection means,
It can pass through the inside of the door stile or through small gaps outside the stile, is simple in configuration, and operates reliably.

In addition, since the steady rest is always biased outward by a spring, when the door that has been opened by swinging is set to the open/closed state by sliding, even if the timing of engagement with the lower rail is slightly off, the spring will keep the steady rest pressed outward. The extruded steady rest is in contact with the floor surface, and when the door is swung in the swing direction, it smoothly engages with the lower rail. Furthermore, since the steady rest is biased outwardly by a spring, it can also be operated by something that only exerts a pulling force, such as a wire.

Furthermore, the drive cam is composed of a drive cam body and a claw piece, and the claw piece rotates together with the main body when the door swings to close, and only the claw piece rotates when the door swings to open. Therefore, when the door swings to close the door, the drive cam rotates and the steady rest protrudes, but when the door swings to open the door, it does not affect the rotation of the drive cam. Even if an attempt is made to push the door in the swing direction by hand or by wind pressure, the steady rest will prevent the door from opening unnecessarily. Also,
Its structure is simple, it operates reliably, and it has the advantage of not breaking down.
