Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sliding door that opens and closes the doorway by running in a direction parallel to the surface of the doorway formed in a wall.

For example, the sliding door that should be installed at the entrance to the vault is made firmly and it is difficult to push it manually. Therefore, a rotating operation handle is installed on the door, and the rotational force of this handle is transferred to a power transmission mechanism. A system has been put into practical use in which the door is moved by transmitting the signal to the running wheels via the .

Such doors are usually provided with a bolt that locks the door to the wall to prevent the door from moving spontaneously and to prevent thieves from entering the room. In addition, some doors have a tightening mechanism that forcefully presses the door against the wall in order to make the strong and heavy door completely adhere to the entrance/exit. However, when a lock and a tightening mechanism are provided in a door with a rotating handle as described above, there is a possibility that the handle is rotated in an attempt to move the door with the bolt and tightening mechanism protruding from the door. There was a risk that the bolt and the tightening mechanism protruding from the door would collide with the edge of the doorway, damaging the bolt.

The purpose of the present invention is to prevent the bolt and the tightening mechanism from protruding from the door when the door is in a movable state, thereby protecting the bolt and the tightening mechanism, and To provide a sliding door in which a bar operating mechanism, a tightening mechanism, and a door running mechanism do not operate unless they are in a predetermined order.

In FIGS. 5, 15, 16, and 17, a shaft 70 is located above the cam plate 35 of the intermediate shaft 29.
The lever 71 is rotatably supported in a vertical plane. A tension spring 72 is interposed between one end of the lever 71 and a suitable stationary part,
A biasing force is applied to the lever 71 in the clockwise rotation direction in FIG. One end of a driven rod 73 is pivotally connected to one arm of the lever 71 and hangs down.
One end of a brake rod 74 is pivotally attached to and hangs down from the other arm of the brake rod 73, and a driven roller 77 rotatably provided at the lower end of the brake rod 73 is driven by the rotation biasing force of the lever 71 to move the cam plate. It is pressed against the cam edge of 35. As shown in FIG. 17, the cam plate 35 is mostly composed of a circular arc portion with the center of the shaft 29 as the center of the circular arc, and a mesial cam edge 75 and this cam edge are located in the middle of this circular arc portion. A notch 76 is formed in the antipodal position of the portion 75. The driven rod 73 and the brake rod 74 are always maintained in a vertical position by appropriate guide members. and the mesial cam edge 75 of the cam plate 35.
This cam edge 75 faces upward and the driven cam 77
When the lever 71 is in pressure contact, the lever 71 rotates due to the force, the lower end of the brake rod 74 comes out of the brake wheel 31, and the cam plate 35 rotates, causing the arcuate cam edge to follow. When the roller 77 rides on the lever 71, the lever 71 is rotated against the biasing force, and the lower end of the brake rod 74 engages between the teeth of the brake wheel 31.

5, FIG. 18, FIG. 19, and FIG. 20, a lever 78 is supported below the cam plate 35 so as to be rotatable in a vertical plane about a shaft 79. A tension spring 81 is applied between one arm 80 of the lever 78 and a suitable stationary part, thereby applying a biasing force to the lever 78 in the left-handed direction in FIG. 19. The other arm 82 of the lever 78 has
One end of a detection rod 83 for detecting that the door 7 closes the entrance/exit 4 is pivotally mounted. Rod 83
passes through a protrusion 16 formed on one side of the door 7, and when the lever 78 is rotated by force, the tip of the rod 83 protrudes from the surface of the protrusion 16. . A flange-like stopper 84 is integrally formed on the rod 83, and when the stopper 84 comes into contact with the inner surface of the protrusion 16, the lever 7
The rotation limit due to the biasing force of 8, therefore the rod 83
The limits of sliding are now defined. When the lever 78 is rotated by force, the end of one arm 80 of the lever 78 can engage with the notch 76 of the cam 35, and the door 7 closes the entrance/exit 4. , Therefore, the protrusion 16 is the wall 2
When the detection rod 83 is fitted into the groove 17 of
is pushed by the wall 2 to rotate the lever 78 against the urging force, and the end of one arm 80 of the lever 78 comes out of the notch 76 of the cam plate 35.

Next, the operation of the above embodiment will be explained. First, when you want to move the door 7 to open or close the entrance/exit 4, pull out the rotary operation handle 9 toward you.
The handle shaft 18 integrated with the handle 9 is biased to the right in FIG.
into the spline shaft hole of the sprocket wheel 22. At this time, the pressure on one arm 27 of the lever 25 by the spline portion 19 of the shaft 18 is released, and the lever 25 rotates based on the biasing force, and the one arm 27 of the lever 25 is rotated based on the biasing force.
comes out from between the teeth of sprocket ring 22,
The sprocket wheel 22 becomes rotatable. Therefore,
When the handle 9 is manually rotated, this rotational force is transmitted to the wheels 8, 8 via the sprocket wheel 22, the chain 32, and the sprocket wheels 15, 15, and the wheels 8, 8 are rotationally driven, and the door 7 is rotated on the rail 6.
The vehicle opens and closes the entrance/exit 4 by running in any direction left or right along the road. Note that when the door 6 travels, the guide rollers 12 at the upper end roll while being pressed against the inner surface of the guide groove 13, thereby preventing the door from falling over.

When the door 7 is moved in this manner and the entrance 4 is closed by the door 7, the detection rod 83 protruding from the protrusion 16 of the door 7 is pushed against the wall 2 and the lever 78 resists the force. Then, in Fig. 19, it rotates to the right,
The end of one arm 80 of the lever 78 slips out from between the teeth of the brake wheel 35 on the intermediate shaft 29, making the intermediate shaft 29 rotatable. Then, the handle 9 is pushed in to slide and bias the handle shaft 18 to the left in FIG.
1 into the spline shaft hole. At this time,
One arm 27 of the lever 25 is pushed by the shaft 18 and rotated against the biasing force, and the other arm 26 of the lever 25 engages between the teeth of the sprocket wheel 22, and the sprocket wheel 22 and the sprocket wheel connected thereto are rotated. Ranaru Chain 3
2. Lock sprocket wheels 15, 15 and wheels 8, 8 inoperatively, and then lock door 7 inoperably. In this state, when the handle 9 is rotated in a predetermined direction, this rotational force is transferred to the worm 2.
1. It is transmitted to the intermediate shaft 29 via the worm wheel 30, and is further transmitted from the intermediate shaft 29 to the upper shaft 37 via the sprocket wheel 36, chain 39, and sprocket wheel 38, as well as the sprocket wheel 91 and chain 50. , are transmitted to the lower shaft 48 via the sprocket wheel 49, and each shaft 29, 3
7 and 48 are rotated in a predetermined direction. axis 37
21, the fastening fittings 42, 42 at both ends rotate from the state shown by the chain line 42A to the state shown by the solid line in FIG. When the door 7 is engaged with the wall, the door 7 is tightened against the wall. This kind of tightening work is
Tightening fittings 52, 52 based on the rotation of the lower shaft 48
The same thing can be done by rotating the . Then, in parallel with the above-mentioned tightening operation being performed, the intermediate shaft 29 is rotationally driven, and as a result, the cam plate 35 is rotationally driven, and immediately after the above-mentioned tightening operation is started, as shown in FIG. The driven roller 77 is pushed up by the lift of the cam from the mesial cam edge 75 of the cam plate to the arcuate centrifugal cam edge, and the lever 71 shown in FIG. It is rotated against the force, and the tip of the brake rod 74 engages between teeth on the periphery of the brake wheel 31 that is integral with the sprocket wheel 22, thereby also locking the sprocket wheel 22 so that it cannot rotate. Ru. This brake lever 74 and brake wheel 3
1, the lever 25 is engaged with the teeth of the sprocket wheel 22 by pulling out the handle 9 and engaging the spline portion 19 of the handle shaft 18 with the spline shaft hole of the sprocket wheel 22. Since the door 7 is maintained even in the released state, the door 7 is still locked so that it cannot be moved. That is, the tightening fitting 4
The door 7 cannot be moved while the door 7 is held in the tightened position with respect to the wall body by the door 2, 52, thereby avoiding damage to the tightening device.

Next, rotate the bolt operation lever 53 to release the ninth
When the slide plates 56, 58, 59 and rod 62 shown in the figure are slid to the left in the figure, the bell crank 60 in FIG. The door 7 protrudes from the wall and fits into a hole (not shown) formed in the wall, thereby locking the door 7 so that it cannot be moved. Further, as the rod 62 slides, its tip engages with the notch 90 of the regulating plate 34 as shown in FIGS. 9 and 10, thereby locking the intermediate shaft 29 non-rotatably. Therefore, in this state, the intermediate shaft 29 based on the rotational operation of the handle 9
The rotational drive of the clamping fittings 42, 52 becomes impossible.
The tightened state will be maintained as it is. When the door 7 is locked by the bolt 61 as described above, the bolt 64 of the cylinder lock 11 faces the notch 65 of the sliding plate 59, so that the cylinder is locked as shown in FIG. When the bolt 64 is protruded from the lock body 63 by the locking operation, the bolt 6
4 fits into the notch 65, and locks the sliding plate 59, the sliding plates 58, 58 integrated therewith, and the rod 62 immovably, and the locked state of the door 7 by the bolt 61 is maintained.

Furthermore, when the locking operation of another cylinder lock 10 causes the bolt 67 to protrude from the main body 66, the bolt 67
A brake wheel 3 whose tip end is integral with the sprocket wheel 22
This also locks the door 7 against movement.

When attempting to open the doorway 4 by moving the door 7 from the state where the doorway 4 is closed in this manner, the procedure described below is performed. That is,
First, the cylinder lock 11 is unlocked to disengage the lock 64 from the notch 65 of the sliding plate 59, and the lock operation lever 53 is rotated in the opposite direction to the above case to lock each integrated slide. Moving plates 56, 58, 59 and rod 62
is slid to the right in Fig. 9, and the rod 6
2 is separated from the notch 90 of the regulating plate 34, and the bell crank 60 is rotated to the right in FIG. 8 to retract the bolt 61 into the door 7 and release the fitting between the wall and the bolt. In this way, the cylinder lock 11 is unlocked,
In addition, when the lock 61 and the wall are disengaged by operating the lock operation lever 53, the intermediate shaft 29 is in a rotatable state, so the handle 9 is pushed in and the spline portion 19 of the shaft 18 is rotated. The handle 9 is fitted into the spline shaft hole of the worm 21.
Rotate in the opposite direction to the above case. The rotational force of the handle 9 is transmitted to the intermediate shaft 29 and the upper and lower shafts 37 and 48 via the power transmission mechanism described above, and
7 and 48 rotate in the opposite direction, the fastening of the door 7 against the wall is released, and the metal fittings 42 and 52 are retracted into the door 7. When the metal fittings 42 and 52 have finished retracting into the door 7, the driven roller 77 falls down on the mesial cam edge 75 of the cam plate 35 on the intermediate shaft 29, and the lever 71 rotates by its habit. Brake rod 74
The tip of the brake wheel slips out from between the teeth of the brake wheel 31, which is integrated with the sprocket wheel. However, at this point, the tip of the bolt 67 of the cylinder lock 10 is still engaged between the teeth of the brake wheel 31 and the door 7 is locked so that it cannot be moved. , the cylinder lock 10 is unlocked in advance or the cylinder lock 10 is unlocked at this point, and the tip of the bolt 67 is allowed to slip out from between the teeth of the brake wheel 31. Then, pull out the handle 9 and slide the shaft 18 to the right in FIG.
9 from the spline shaft hole of the worm 21 and the spline portion 19 from the sprocket wheel 2.
Fit into the spline shaft hole of No.2. When the shaft 18 is slid and biased as described above, the lever 25 is rotated by the force, and the engagement between the one arm 26 of the lever 25 and the teeth of the sprocket wheel 22 is released, and the sprocket wheel 22 is now rotated. It becomes possible to rotate. When the handle 9 is rotated in a predetermined direction, the rotational force of the handle 9 is transmitted to the traveling wheels 8, 8 via the power transmission mechanism described above, and the rotation of the wheels 8, 8 causes the door 7 to close the doorway 4. Move in the direction of opening. When the protrusion 16 of the door 7 separates even slightly from the groove 17 of the wall 2, the pressure on the detection rod 83 by the wall is released, and the lever 78 rotates based on the elasticity of the spring 81, and the detection rod 83 protrudes from the protrusion 16 of the door 7, and the lever 78
Based on the above rotation, the end of one arm 80 of the lever engages with the notch 76 of the cam plate 35, thereby preventing the intermediate shaft 29 from rotating. That is, this means that unless the entrance/exit 4 is completely closed by the door 7, the intermediate shaft 2
9 is prevented from rotating, and therefore, it is impossible for the fastening fittings 42, 52 to protrude from the door 7 unless the entrance 4 is completely closed by the door 7. Therefore, the metal fittings 42, 52
The door 7 moves with the door 7 protruding from the door 7, and the metal fitting 4
This prevents damage to the parts 2 and 52. When the door 7 is running and the entrance 4 is open, the handle 9 is pushed in and the lever 25 is rotated against the urging force so that the arm 26 of the lever 25 is engaged between the teeth of the sprocket wheel 22. , or lock the cylinder lock 10 and engage the tip of the bolt 67 between the teeth of the brake wheel 31 to lock the sprocket wheel 2.
From the viewpoint of safety, it is preferable to lock the door 2 so that it cannot rotate so that the door 7 does not move accidentally.

In addition, when the fastening fittings 42 and 52 are retracted into the door 7 as described above, that is, when the door 7 can move, the notch 90 of the regulating plate 34 is moved away from the position facing the tip of the rod 62. Since the rod 62 cannot be moved due to misalignment, the lock operation lever 5 cannot be moved.
3 cannot be operated, and the bolt 61 cannot be made to protrude from the door. In other words, the bolt 61 cannot protrude from the door body when the door 7 is in a state where it can move, so the door does not run with the bolt protruding.
Breakage of the bolt can be prevented.

According to the present invention, there is provided a braking member that allows rotation of the intermediate shaft for operating the tightening mechanism only when the opening/closing detection member detects that the door closes the entrance/exit; A regulating member moves by rotating the door in a direction that tightens the door against the wall and restricts the movement of the power transmission mechanism for driving the door, and a bolt operating mechanism operates by fitting the bolt into the wall to provide the above-mentioned A locking mechanism that locks the intermediate shaft so that it cannot rotate is installed, so when opening the doorway, it will only operate in the predetermined order of unlocking, releasing the bolt, and moving the door, and when closing the doorway, , it will not operate unless the door travels, the tightening mechanism is activated, and the bolt operating mechanism is activated, and when the doorway is open, the tightening mechanism and the bolt operating mechanism are activated by the detection operation of the opening/closing detection member. Therefore, it is impossible to run the door in the closing direction with the bolt and the tightening member protruding from the door, and thus the bolt operating mechanism and the tightening mechanism can be protected. .
