6 passes through an elongated hole 60 drilled in the support plate 59 in the horizontal direction (in the vertical direction in FIG. 12), and the bolt 58 passes through the bent portion 61 of the support plate 59, and then bolts into the double nut 62, 62. Therefore, double nuts 62,6
When the movable plate 57 and the shaft 56 integral therewith are moved along the elongated hole 60 by the adjustment in step 2, the sprocket wheel 55 is moved and the tension of the chain 54 is adjusted.

As shown in FIGS. 4, 5, and 9, a shaft 63 is also rotatably supported at the lower part of the back side of the door 6 in parallel with the intermediate shaft 36. As shown in FIGS. axis 6
A sprocket wheel 64 having approximately the same diameter as the sprocket wheel 39 is fixedly mounted in the center of the sprocket wheel 3, and an endless chain 65 is hung between the sprocket wheels 39 and 64. A sprocket wheel 66 for tension adjustment is pressed against the chain 65, as also shown in FIG. The support structure of the sprocket wheel 66 is as follows:
Since the structure is similar to the support structure of the sprocket wheel 55 already explained with reference to FIG.
Identical constituent members are given the same reference numerals as those in FIG. 12, and detailed description thereof will be omitted. As shown in FIGS. 4, 9, 15 and 16, eccentric cams 67 are provided at both ends of the shaft 63 at positions facing the receiving groove members 21 of the overhanging member 20.
67 is fixed. These cams 67, 67
is fixed to the overhanging member 20 and is located in a through hole 71 of a driven member 70 passing through an elongated hole 69 bored in the receiving groove member 21, as shown in FIG. , the proximal part of the cam 67 is connected to the driven member 7.
By contacting one edge of the through hole 71 of 0, the overhanging member 20 is in a state of being retracted into the receiving groove member 21 by the urging force based on the elasticity of the spring 24. In addition,
Eccentric cams 68, 68 similar to the eccentric cam 67 are fixed to both ends of the shaft 52 (see FIG. 4). These eccentric cams 68, 68 are also located in the through hole of the driven member configured similarly to the driven member 70, and normally the proximal portions of the cams 68, 68 abut one edge of the through hole of the driven member. This allows the overhanging member 20 to retreat based on the elasticity of the spring 24.

In FIG. 4, an endless chain 7 is attached to the sprocket foil 29 on the handle shaft 25 and the sprocket foils 19, 19 on the traveling wheel shafts 18, 18.
2 are hung in a triangular shape. A tension adjusting sprocket wheel 73 provided between the wheels 7 is pressed against the chain 72.
It is assumed that the support structure for the sprocket wheel 73 is constructed in the same manner as that described with reference to FIGS. 12 and 14.

In FIG. 4, from the upper end of the back of the door 6,
The roller 7 is inserted through the two window holes drilled in the back of the door 6.
A part of the circumferential surface of 4 and 74 protrudes. roller 7

It is rotatably supported in a horizontal plane by a rod 75, and the rod 75 is held slidably in the longitudinal direction by an inverted U-shaped holder 76 fixed to the door body. The rod 75 is provided with a flange 77, and a repulsion spring 78 is interposed between the flange 77 and the holder 76, so that the rod 75 is biased in the direction of sliding to the left in FIG. A biasing force is given. Sliding due to this biasing force is restricted by the flange 77 coming into contact with the holding body 76. However, as shown in FIG. 6, the roller 74 protruding from the back of the door is
The rod 75 is in pressure contact with a guide protrusion 79 made of the same material as that of the rod 75, and is in a state of being slightly biased to the right against the elasticity of the spring 78.

Also, two rollers 80 and 8 can be seen from the lower end of the back surface of the door 6 through two window holes bored in the back surface of the door 6.
A part of the circumferential surface of 0 protrudes. The details of the support structure for the roller 80 are shown in FIGS. 7 and 10, and the support structure includes a rod 81, a holder 82, a flange 83, and a spring 84, similar to the support structure for the roller 74. The roller 80 comprises:
Based on the elasticity of the spring 84, the wall body is pressed against a guide protrusion 85 provided on the side.

Next, the operation of the present invention will be explained. First, entrance 4
When moving the door 6 to open or close it, pull out the rotary operating handle 9 toward you, bias the handle shaft 25 that is integrated with the handle 9 to the right in FIG. into the spline portion of the sprocket foil 29. At this time, the pressure on one arm 35 of the lever 32 by the spline portion 26 of the shaft 25 is released, the lever 32 rotates based on the urging force, and the one arm 33 of the lever comes out from between the teeth of the sprocket wheel 29, so that the sprocket The foil 29 becomes rotatable.
Therefore, when the handle 9 is manually rotated,
This rotational force is transmitted to the wheels 7, 7 via the sprocket wheel 29, the chain 72, and the sprocket wheels 19, 19, and the wheels 7, 7 are rotationally driven to move the door 6 along the rail 5 in any left or right direction. The vehicle then runs to open and close the entrance/exit 4. Note that when the door 6 travels, the upper and lower rollers 74 and 80 move along the guide ridges 79 and 80.
85 and the upper guide rollers 14, 14 roll while being pressed against the inner surface of the guide rail 15, which prevents the door from rattling and falling. .

When the door 6 is moved in this manner and the entrance/exit 4 is closed by the door 6, the handle 9 is pushed in to bias the handle shaft 25 to the left in FIG. 2
After fitting into the spline portion 8, the handle 9 is rotated. At this time, one arm 35 of the lever 32 is pushed by the shaft 25 and rotates against the biasing force, and the one arm 33 of the lever 32 engages between the teeth of the sprocket foil 29, causing the sprocket foil to rotate. 29 is prevented from rotating, and as a result, the chain 72, the sprocket wheels 19, 19, and the wheels 7, 7 are also prevented from rotating, and the door 6 is prevented from running freely. When the handle 9 is rotated as described above, this rotational force is transferred from the worm wheel 37 to the intermediate shaft 36.
and the sprocket foil 38,
It is transmitted to the shaft 52 via the chain 54 and sprocket wheel 53, and further transmitted to the shaft 63 via the sprocket wheel 39, chain 65 and sprocket wheel 64. In this way, when the intermediate shaft 36 rotates, the clamping fittings 4 at both ends thereof
2 and 42 rotate together, and the metal fitting 42 changes from a position in which it is retracted into the space 43 as shown by a chain line 42A in FIG. 18 to a position in which it protrudes from the space 43 as shown in a solid line. The hook portion of the metal fitting 42 engages with the tightening shaft 46 in the space 45 next to the wall, and the door 6 is drawn to the wall, so that the door 6 is brought into close contact with the wall. Further, by rotationally driving the shaft 52 and the shaft 63, the eccentric cams 68 at both ends of the shaft 52 and the eccentric cams 67 at both ends of the shaft 63 rotate. Due to the rotation of these cams 68 and 67, the cam 6 is shown in FIG.
7, the distal edge of the cam 67 is connected to the through hole 7 of the driven member 70 integral with the overhang member 20.
1 to push the overhang member 20 outward from the receiving groove member 21. The extruded overhanging member 20 is
As shown in FIGS. 2 and 17, the door 6 is fitted into the left and right edges and the upper edge of the doorway 4, and is locked so that the door 6 cannot be moved.

Furthermore, when the combination locks 10 and 11 are operated with the door 6 locked so that it cannot run as described above, the bolts 50 and 51 protrude from the combination lock bodies 48 and 49, as shown in FIG. The brake wheels 40 and 41 are engaged between teeth on their peripheries. As a result, each shaft 36, 52, 63 is locked so that it cannot rotate, and the result is the same as if the door 6 was locked.

Next, when trying to open the entrance/exit 4, first unlock the combination locks 10, 11 and then press the bolts 50, 5.
1 from between the teeth of the brake wheels 40, 41, and then rotate the handle 9 in the opposite direction to the above case with the spline portion 26 of the handle shaft 25 fitted to the spline portion of the worm 28. Each axis 3
6, 52, and 63 in the opposite direction, and the eccentric cam 6
8 and 67 toward the original position to retract the overhanging member 20 into the receiving groove member 21, and at the same time, rotate the fastening fitting 42 toward the original position to remove the fastening fitting 42. The hook portion is separated from the tightening shaft 46. After that, pull the handle 9 toward you and attach the spline portion 26 of the handle shaft 25 to the sprocket foil 2.
If the door 6 is fitted into the spline portion 9 and the handle 9 is rotated in this state, the door 6 will run along the rail 5 and open the entrance/exit 4 as described above.

As described above, according to the present invention, it is possible to perform the door traveling operation and the door locking operation with one rotary operation handle, so that the door traveling operation and door locking operation, the door unlocking operation, and the door locking operation can be performed. Since the intermediate shaft for operating the lock mechanism is restrained by the lock so that it cannot rotate, the structure of the locking device can be simplified.
