A double sliding door type gate according to an embodiment of the present invention will be described with reference to the drawings.
First, the overall schematic configuration will be described with reference to FIG.
Two double sliding door type gates 1 are installed, and the entrance is closed when both are extended to the maximum.
As shown in FIG. 2, in the double sliding door type gate 1, a base anchor 3 is provided with a hanging gatepost 5, and a main door 7 is rotatably supported on the hanging gatepost 5. As shown in FIG. The main door 7 has two door bodies 9, 9 erected parallel to each other with an interval therebetween, and roller covers 11, 11 respectively cover the upper and lower ends thereof. Connecting portions 13, 13, .
There is a gap between the lower surface of the door body 9 of the parent door 7 and the ground where it is installed, and the parent door 7 is supported by the hanging gate post 5 in a cantilevered protruding manner.

The gap between the two door bodies 9, 9 of the parent door 7 serves as a storage space for the door body 15 of the sliding door (hereinafter referred to as "sliding door door body 15"), and the door body 15 is pulled out from this storage space. Then, the double sliding door type gate 1 extends.
Even when the sliding door door body 15 is extended to the maximum, the hanging gatepost 5 side of the sliding door door body 15 overlaps with the door bodies 9, 9 of the parent door 7. - 特許庁In this overlapped portion 17 (FIG. 11), guide rollers (not shown) are rotatably protruded on both sides in the moving direction of the upper end and the lower end. A roller slides on the inner surface of the roller cover 11 on the main door 7 side. A stopper roller (not shown) protrudes from the lower surface of the overlapped portion 17, and when it abuts against a contact portion (not shown) on the parent door 7 side, further extension is prevented.

This double sliding door type gate 1 is provided with an adjuster mechanism 19 .
As shown in the perspective views of FIGS. 3 and 4, the plate surface of a rectangular base plate 21 is fixed to the lower surfaces of the two door members 9, 9 of the parent door 7 across the gap between them. A pair of opposed edge portions of the base plate 21 are along the outer door surfaces of the door bodies 9, 9 and do not protrude outward.
A rectangular stopper insertion hole 23 is formed in the base plate 21 in a similar manner. The stopper insertion hole 23 opens the gap in the vertical direction, and the lower surface of the sliding door body 15 is exposed to the ground.

The base plate 21 has a pair of bearings 25, 25 protruding downward. The bearings 25, 25 face the lower surfaces of the doors 9, 9, respectively, with the base plate 21 interposed therebetween, and are integrated by welding at overlapping positions in the direction perpendicular to the door surface of the door 9. As shown in FIG.
The bearing 25 is constructed by arranging two bearing plates 27, 27 parallel to each other, and the upper end plate thickness surfaces of the plates are integrated by welding. Both side edges of the bearing plate 27 are parallel on the upper side, but are rounded in an arc shape on the lower side. The plate surfaces of the bearing plates 27, 27 are arranged parallel to the plate surfaces of the door bodies 9, 9, and the respective insertion holes are opened in a direction orthogonal to the plate surfaces of the door bodies 9, 9.

Using the pair of bearings 25, 25, the mounting portion 29 is rotatably supported. The attachment portion 29 is configured by combining plate members. The side portions 33, 33 are vertically welded to the opposite short side edges of the rectangular bottom portion 31 and stand up. The side portion 33 is also substantially rectangular, and one short side edge of the side portion 33 is welded together. The upper short side edge 35 is pivoted directly under the door 9, and the corner 37 closest to the underside of the door 9 is rounded. In addition, the side opposite to the corner 37 is extended, and the short side edge 35 is lengthened accordingly. An insertion hole similar to the insertion hole of the bearing plate 27 is formed in the vicinity of the short side edge 35 .
A rear portion 39 is integrated with the side portions 33, 33 and the bottom portion 31 by welding on the rear side and reinforced. In addition, the rear portion 39 is located below the extension portion of the side portion 33 and does not interfere with the extension portion.

Each side surface portion 33 of the mounting portion 29 is inserted into the gap between the two bearing plates 27, 27 of the bearing 25, and fastened with bolts and nuts 41 in a state in which the respective insertion holes communicate with each other. That is, the mounting portion 29 is rotatably supported. Since the round corner 37 of the side surface 33 faces the lower surface of the base plate 21 with a slight gap when the mounting portion 29 is rotated, the mounting portion 29 can be rotated even when the fulcrum of rotation is near the lower surface of the base plate 21. It has become.

As shown in FIGS. 3 and 5, when folded toward the base plate 21, the back surface 39 faces downward. Since the support position by the mounting portion 29 is near the edge of the base plate 21, the mounting portion 29 is accommodated within the base plate 21 in the folded position.
Since it is rotatably suspended like a swing, when it is freely rotatable, the bottom portion 31 is in a hanging posture facing the ground as shown in FIG. When viewed in a side view, the mounting portion 29 changes from the folded posture shown in FIG. 5 to the suspended posture shown in FIG.

FIG. 4 is a drawing in which the base plate 21 is omitted from FIG. As shown in FIGS. 4 and 8, the bottom portion 31 of the mounting portion 29 is formed with two spaced insertion holes through which the leg shafts 43, 43 are inserted. Inside the mounting portion 29, a nut 44 fixed to the bottom portion 31 is screwed and fixed to the male screw on the leg shaft 43 side. The leg shaft 43 extends from the bottom surface portion 31 in a direction perpendicular to its plate surface, and a ground pad 45 is provided at its tip. A leg portion 47 is composed of the leg shaft 43 and the ground pad 45 . The leg portion 47 stands in a landing posture when the mounting portion 29 is in a hanging posture, and the grounding pad 45 can be grounded on the ground.

Further, as shown in FIG. 7, abutting portion 49 for restricting movement of the sliding door body 15 is attached to the attaching portion 29 . The fixed arm portion 51 is made of a flat plate material and is formed in the shape of the letter "". A rubber abutting portion 49 is attached to the tip of the remaining inclined portion 55 . The vertical portion 53 is welded to the bottom portion 31 and the rear portion 39 in the middle so that the side portions 33, 33 and the plate surfaces are aligned parallel to each other, and the inclined portion 55 is formed outside the side portions 33, 33. It extends far out in the direction.
When the mounting portion 29 is in the hanging posture, the abutting portion 49 at its upper end is below the base plate 21 . On the other hand, when it rotates to the folding position, it enters from the stopper insertion hole 23 of the base plate 21 toward the sliding door body 15 side.

A stopper piece 57 is fixed to the lower surface of the sliding door body 15 as the side that is abutted against the abutting portion 49 . The stopper piece 57 is formed by vertically bending a rectangular plate material to have an L-shaped cross section. One piece is fixed to the lower surface, and the stopper piece 57 projects vertically downward. The plate surface of the stopper piece 57 faces the moving direction of the sliding door body 15 .
When the mounting portion 29 changes from the hanging posture to the folding posture, the abutting portion 49 approaches the sliding door door body 15 side by rotation and abuts against the stopper piece 57 in an abutting state. When the sliding door door body 15 moves in the closing direction, the stopper piece 57 moves in the direction of contact with the abutting portion 49 . Therefore, when the mounting portion 29 is in the folded posture, the sliding door body 15 cannot move in the closing direction.
On the other hand, when the mounting portion 29 is in the hanging posture, the abutting portion 49 is disengaged from the abutting position, so that the sliding door body 15 can move in the closing direction.

When the double sliding door type gate 1 is opened, the sliding door body 15 is fixed in the housed state, and the abutting part 49 is locked in the abutting state against the stopper piece 57 so as not to be pulled out. Locking means are provided.
As shown in FIGS. 6 and 8, a pivot bracket 59 is attached to the lower portion of the outward facing door surface of one of the door members 9, 9 of the parent door 7. Both ends of the support shaft 61 are fixed to the shaft support brackets 59 . This support shaft 61 is perpendicular to the door surface. The shaft support bracket 59 is open in the vertical direction and in the direction in which the sliding door body 15 is pulled out, and an elongated plate-like rocking arm 63 is inserted therethrough.

The rocking arm 63 has a locking groove 65 formed in the middle edge in the longitudinal direction. A fulcrum concave portion 67 is formed on the edge in the longitudinal direction opposite to the formation side of the locking groove 65, and an engaging concave portion 69 recessed in an arc shape is formed on the lower side thereof.
With the fulcrum recessed portion 67 of the swing arm 63 fitted onto the support shaft 61 , the connecting portion 73 of the double torsion spring 71 is locked in the locking groove 65 , and the coil portions 75 , 75 on both sides are connected to the support shaft 61 . It is wound, and both end sides are fixed to pivot brackets 59 . By the double torsion spring 71, the swing arm 63 is supported swingably in a seesaw shape with the support shaft 61 as a swing fulcrum, and the biasing direction of the spring is clockwise in the side view of FIG. ing. The engaging recess 69 is located below the door body 9 of the main door 7 in the swinging range.

A lock shaft 77 protrudes outward in the orthogonal direction from the outer surface of the side surface portion 33 of the mounting portion 29 . Since this lock shaft 77 is interlocked with the mounting portion 29, it moves on an arc track. Since the swinging orbit of the swinging arm 63 intersects with this arcuate orbit, when the lock shaft 77 is lifted toward the engaging recess 69 by foot motion or manually, it hits the edge of the swinging arm 63 and the swinging arm 63 is biased. When it is swung in the opposite direction and pulled up further, it enters into the engagement recess 69 and engages. Since the force is applied in the direction of maintaining the engagement, if the foot or hand is released at this point, the engagement state is maintained and the mounting portion 29 is locked in the folded position as shown in FIG.
Then, when the upper side of the swing arm 63 is pushed down to swing counterclockwise from the engaged state, the engaged state is released and the lock shaft 77 is disengaged from the engagement recess 69 . Accordingly, the mounting portion 29 is freely rotatable and takes a hanging posture under its own weight.

The adjuster mechanism 19 is configured as described above, and is provided on the free end side of the main door 7, that is, at the position where it is supported when the sliding door body 15 is pulled out and cantilevered.
The operation of the adjuster mechanism 19 for lightening the opening and closing work of the double sliding door type gate 1 will be described with reference to FIG.
In the open state shown in FIG. 2, that is, in the state in which the sliding door body 15 is retracted, it is locked. When this is released, the mounting portion 29 rotates in the direction indicated by the arrow due to its own weight, and the leg portion 47 is pulled out. landing posture. However, at this time, the ground pad 45 is floating from the ground (GL). The abutment portion 49 abuts against the stopper piece 57 when locked, but when the lock is released, the abutment portion 49 rotates and descends, so that the sliding door body 15 can be pulled out.

As shown in FIG. 10, when the sliding door body 15 is pulled out, the load on the parent door 7 positioned above the adjuster mechanism 19 increases and the door sagging. Then, as shown in FIG. 11, in the fully pulled out state, the ground pad 45 is placed on the ground (GL), and the support base obtains a reaction force for supporting the load from the ground (GL). can reduce the load. Therefore, the operation of returning the sliding door body 15 in the opening direction, that is, in the storing direction can be performed easily.

The leg portion 47 is grounded on the ground (GL) through the grounding pad 45, so that the ground (GL) can cope with some unevenness and inclination.
Further, when the sliding door body 15 is returned to the storage direction, the grounding pad 45 rises from the ground (GL) on the way, so that the mounting portion 29 can be lightly rotated. Therefore, it can be easily returned to the locked state.
Further, when the double sliding door type gate 1 is opened, the adjuster mechanism 19 can be sufficiently separated from the ground (GL) in the folded state, and the sliding door body 15 can be prevented from jumping out. Therefore, the advantage of the rotary type in which the main door 7 is cantilevered on the gatepost can be utilized as it is. That is, by providing one adjuster mechanism 19, it is possible to alternatively realize a state that is advantageous when opening the double sliding door type gate 1 and a state that is advantageous when rotating.

Although the embodiment of the present invention has been described in detail above, the specific configuration is not limited to this embodiment. Even if there is a change in design in the above, it is included in the invention.
