FIG. 1 shows a telescopic gate according to the present invention, wherein a telescopic gate 1 is disposed between a suspension column 2 and a door stop column 3, and a telescopic gate is provided as shown in FIG. Main pillar 2 and door stop pillar 3
The gate 1 is opened and closed by expanding and contracting the gate 1, and as shown in FIG. 3 and FIGS. 3 (a) and 3 (b), the hanging frame 4 provided at one end of the gate 1 is opened. It is connected so that it can be opened and closed by turning (rotating in the horizontal direction) around the suspension column 2.

In the gate 1, a plurality of vertical bars 6 are disposed between the hanging frame 4 and the door stop frame 5 at both ends, and these frames and the vertical bars 6 are formed in an elongated frame shape. A plurality of links 7 arranged in a pantograph shape are arranged in the opening, and the intersections of the links 7 having different directions are connected by a rotating shaft 8, and the rotating shafts 8 correspond to the upper and lower rows every other row. 3 (a) and 3 (b), the both ends thereof are slidably inserted into a guide groove 9 formed along the longitudinal direction of the hanging frame 4, the door stop frame (not shown), and the vertical bar 6 as shown in FIGS. It is engaged. However, the center rotating shaft 8a is composed of a hanging frame 4, a door frame 5, and a vertical rail 6.
And is configured not to slide. Thereby, the gate 1 expands and contracts while the rotating shaft 8 except the fixed shaft 8a slides vertically along the hanging frame 4, the door stop frame 5, and the guide groove 9 of the vertical bar 6.

Next, as shown in FIGS. 3A and 4, the site side in the entry / exit direction of the hanging frame 4 disposed on the hanging column 2 side of the gate 1 is the same as the hanging column 2. Is connected to the same side via a hinge fitting 10. Therefore, the gate 1 can be rotated in the horizontal direction about the rotation axis 11 of the hinge fitting 10, and the rotation allows the opening between the columns 2 and 3 to be wider.

The gate 1 is configured to be held in a closed state by a rotation stopper 12 and a receiving member 13.

That is, the rotation stopper 12 is slidable along a guide groove 9a formed in the longitudinal direction of the hanging frame 4 and is provided with a slider 14 protruding laterally from the hanging frame 4. It is composed of a stop piece 15 and an engagement piece 16 projecting at a right angle from the base of the locking piece 15, and is disposed on the road side (the opposite side of the hinge fitting 10) in the direction of entry and exit of the hanging frame 4. A concave portion 17 is formed at the base of the lower edge 15a of the locking piece 15, as shown in FIG. Lower edge 15a of locking piece 15
Is inclined upward through the recess 17. An oval operation hole 18 is formed at the center of the locking piece 15. The locking piece 15 is formed so as to protrude toward the hanging column 2.

Reference numeral 20 denotes a stopper for stopping the rotation stopper 12 at a predetermined position. The stopper 20 is fixed to the guide groove 9a and has an upper end engaged with the engagement piece 16. Therefore, the rotation stopper 12 can slide up and down along the guide groove 9a above the position where the rotation stopper 12 engages with and stops at the stopper 20.

On the other hand, a rectangular plate-shaped receiving member 13 is fixed to the hanging column 2. A part of the receiving fitting 13 protrudes in and out. The receiving bracket 13 is disposed at a position corresponding to the inclined lower edge 15 a of the rotation stopper 12.

Reference numeral 21 denotes a back plate for fixing the receiving bracket 13 to the hanging column 2. The back plate 21 is substantially rectangular, and the inclined lower edge 15 of the rotation stopper 12 in the guide groove 9 b of the hanging frame 2.
It is arranged at a position corresponding to a.

The door stile 5 of the gate 1 and the intermediate vertical rail 6
A pair of left and right casters 22 is attached to the lower part of the. The door stop frame 5 is provided with a lock 24 interlocking with the handle 23, and the door stop post 3 is provided with a rod-shaped lock receiver 25 for locking the lock 24.

Next, the mode of use of the gate 1 having the above structure will be described. When closing the opening between the door stop post 3 and the hanging post 2, the gate 1 is extended and the handle 23 is turned. What is necessary is just to lock the lock 24 with the lock receiver 25 of the door stop pillar 3. To open the opening, the handle 23 is unlocked 24, and the gate 1 may be contracted to the hanging column 2. Further, when a large opening is to be obtained, a finger is inserted into the hole 18 of the locking piece 15 of the rotation stopper 12, and the rotation stopper 12 is slid upward to release the engagement with the receiving bracket 13, and the contracted gate 3 may be rotated in the horizontal direction via the hinge fitting 10 as shown in FIG. Thereafter, when the gate 1 is rotated in the opposite closing direction from the state of FIG. 3 (b) as shown in FIG. 3 (a), as shown in FIGS. 5 (a), 5 (b) and 5 (c), In the vicinity of the moving end, the inclined lower edge 15a of the locking piece 15 of the rotation stopper 12 engages with the receiving member 13, so that the rotation stopper 12 is pushed upward and slides, and is received by the rotating end of the gate 1. When the metal fitting 13 passes over the lower edge 15a, it slides downward and is locked in the concave portion 17. Therefore, the rotation stopper 12 is automatically locked by the receiving bracket 13 and cannot be rotated.

As described above, when the gate 1 is rotated in the horizontal direction, the rotation stopper 12 may be slid with one hand when rotating in the opening direction, and may be slid with one hand when rotating in the opening direction. The rotation stopper 12 is automatically slid and locked to the receiving bracket 13. Therefore, the operation becomes very simple. Moreover, since the structure is simple, it can be realized at low cost.

The rotation stopper 12 and the receiving member 13
May be configured to be attached to the hanging column 2 and the hanging frame 4, respectively, instead of being attached to the hanging frame 4 and the hanging column 2 as described above. In this case, it goes without saying that the rotation stopper 12 protrudes toward the hanging frame 4.

[0019]

According to the first aspect of the present invention, a rotation stopper is slidably mounted on the road in the direction of entry and exit of the hanging frame so as to be vertically slidable, while the rotation stopper projects toward the hanging pillar. The lower edge of the rotation stopper is inclined downward through the recessed portion, and a receiving bracket is provided on the road side of the suspension column at a position corresponding to the inclined lower edge of the rotation stopper. When the gate is rotated horizontally and closed, the inclined portion of the lower edge of the rotation stopper is engaged with the receiving member and slides upward, so that it is locked in the recess. When rotating the gate horizontally, the rotation stopper only needs to be slid with one hand to rotate in the opening direction, and the rotation stopper engages with the receiving bracket when rotating in the closing direction. Then automatically slide up after It is engaged in the recess of the receiving bracket. Therefore, the operation becomes very simple. Moreover, since the structure is simple, it can be realized at low cost.

The same effect can be obtained by the invention according to claim 2.
