BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gate that prevents the drop bar from being lifted up when the gate body is closed and allows the height of the drop bar to be adjusted freely. .

[0002]

2. Description of the Related Art An example of a conventional gate is shown in FIGS. 8 to 12, in which 1 and 2 are left and right gate posts standing on the ground 15, and 3 and 4 are horizontally opened and closed in a double-door type. It is a gate main body attached to the left and right gate posts 1 and 2 via hinges 5 and 6 so as to be capable.

A vertically oriented guide cylinder 7 is attached to the lower part of the vertical member 3a of the gate main body 3 facing the vertical member 4a of the gate main body 3 so as to be positioned inside the gate. 8 is fitted and inserted. Thus, the guide tube 7 is provided with a guide groove 7a extending in the vertical direction, and the knob 8a projecting outward from the drop rod 8 in the radial direction penetrates the guide groove 7a of the guide tube 7. And a guide groove 7b, one end of which is connected to the guide groove 7a, is provided in the circumferential direction at a required position in the vertical direction of the guide cylinder 7, and the drop rod 8 By inserting the knob 8a into the guide groove 7b, the drop bar 8 can be made to stand by at a required position in the height direction.

At a required position of the vertical member 4a of the main gate body 4 facing the main gate body 3, for example, the vertical member 4a is horizontally penetrated from the inside of the gate to the outside of the gate, and the grips 9 and 10 are attached to both ends of the operating member. 11 is rotatably attached, and an engaging member 12 is projected outward in the radial direction of the operating member 11 at a portion located inside the gate of the operating member 11, and the operating member 11 is operated to operate the engaging member 11. Reference numeral 12 is adapted to engage with a hook 13 attached to a required position of the vertical member 3a of the gate body 3.

In the figure, 14 is a door stop and 16 is a drop bar 8.
Is a hole drilled in the ground 15 so that the lower part of the is inserted.

If the gate bodies 3 and 4 are closed,
The drop bar 8 drops as the knob 8a descends along the guide groove 7a, and the lower end is fitted into the hole 16 provided in the ground 15 as shown in FIGS.
Engages the hook 13 in the horizontal direction.

When passing through the gate, the grip 9 or 10 is gripped and the operating member 11 is rotated to disengage the engaging member 12 from the hook 13 and pull the grip 9 or push the grip 10 to hinge the gate main body 4. The gate main body 4 is opened by horizontally rotating about 6. Further, after passing through the gate, the grip 10 is pulled or the grip 9 is pushed, the gate body 4 is rotated and closed until it comes into contact with the door stop 14, and the operation member 11 is rotated via the grip 9 or 10. By doing so, the engaging member 12 is hooked 13
Engage with.

When opening the gate main body 3 in addition to the gate main body 4, the drop bar 8 is lifted along the guide groove 7a by holding the knob 8a, the lower end thereof is disengaged from the hole 16, and the knob 8a is set in the guide groove 7b. The along guide tube 7 is rotated in the circumferential direction. As a result, the drop bar 8 also rotates in the circumferential direction of the guide cylinder 7, and the knob 8a fits into and engages with the guide groove 7b of the guide cylinder 7.
The drop bar 8 does not fall even if the finger is removed from the knob 8a, and the lower end thereof is located above the ground 15. Therefore, in this case, both the gate main bodies 3 and 4 can be opened.

[0009]

However, in the above-mentioned gate, i) Even when the gate main bodies 3 and 4 are closed, the drop rod 8 can be lifted by being pinched with fingers, and thus the drop rod can be raised. When 8 is raised and the lower end is disengaged from the hole 16, even if the engaging member 12 is engaged with the hook 13, the gate bodies 3 and 4 may open naturally, which is not preferable for crime prevention. Ii) When the ground 15 is inclined in the opening direction of the gate main bodies 3 and 4 as shown in FIG. 10, the knob 8a is engaged with the lower guide groove 7b of the guide cylinder 7 so that the drop bar 8 is engaged. Even if the door is raised, the lower end of the dropping bar 8 may come into contact with the ground 15 when the gate body 3 is opened. In this case, the knob 8a
There is a problem that the dropping bar 8 has to be raised up so as to engage with the upper guide groove 7b, and the operation is troublesome.

In view of the above situation, the present invention prevents the drop rod 8 from being raised when the gate main bodies 3 and 4 are closed, and also raises the height when the drop rod 8 is raised. The purpose of this is to adjust the position at a fine pitch.

DISCLOSURE OF THE INVENTION The present invention provides a box body in which one of the left and right gate bodies that can be opened in a double door is opened so that when the two gate bodies are closed, the surface facing the other gate body is opened. Along with the mounting of the box, a plurality of protrusions having a rectangular vertical cross-section projecting toward the opening are provided on the back surface of the box facing the opening at required intervals, and the box penetrates the bottom surface of the box. At the top of the drop bar that was installed to extend into the body, the thickness of the side facing the back of the box was rectangular and the height of the recess between the upper and lower protrusions formed on the back of the box. A slide block smaller than the size is slidably mounted in a direction parallel to the direction from the opening of the box to the back side, and the slide block is urged toward the back side of the box through the hole formed in the slide block. It contains an elastic body.

[0012]

[Operation] When the left and right gate bodies are closed, the slide block slides even if an operator tries to lift the drop bar between the lower edge of the gate body bottom edge and the ground with fingers. It is not possible to lift the drop bar because it engages with the projection at the top of the box back recess in which the block is fitted. Therefore, if the lower end of the drop bar is fitted in the hole provided in the ground, the drop bar cannot be removed from the hole while the left and right gate bodies are closed, and It does not open naturally, which is advantageous for crime prevention.

Further, when the gate main body provided with the drop bar is opened, even if the ground is inclined in the rising direction in the opening direction of the gate main body, the position of the lower end of the drop bar can be adjusted according to the inclination. Is easy.

A horizontal hole 23c is formed, and the spring 24 can be housed in the horizontal hole 23c in a compressed state as shown in FIG. Further, as shown in FIG. 3, protrusions 23d formed in a slightly concave arc shape in plan view are provided on the front and rear surfaces of the front end side of the slide block 23.

As shown in FIG. 5, the round head screw 22 has a male screw portion 22a which is screwed into a female screw portion formed at the upper end of the drop rod 21, a body portion 22b having a diameter larger than that of the male screw portion 22a, and a body portion. It is formed by a head portion 22c having a diameter larger than that of 22b. The length L1 of the body portion 22b of the round head screw 22 is such that when the slide block 23 is dropped and attached to the upper end of the rod 21, the body portion 22b is inserted into the long hole 23a of the slide block 23 and the male screw portion 22a is dropped. Even if the slide block 23 is screwed onto the upper end of the slide block 23, the slide block 23 can move in the radial direction with respect to the body portion 22b.
It is formed to be slightly larger than the thickness H1 of the portion other than the 3d forming portion.

The thickness H1 of the slide block 23 is formed to be slightly smaller than the interval H2 of the recesses 20h provided on the back surface 20b of the box body 20, and the rear end of the slide block 23 is fitted in the recess 20h. Each protrusion 20c or step 20
d, 20e can be engaged. The outer width W1 of the slide block 23 in the direction orthogonal to the long axis direction of the long hole 23a is slightly smaller than the inner width W2 of the box body 20. Further, the box body 20 of the slide block 23
Depth length D from the opening 20a side to the back 20b side end
1 is formed to have substantially the same depth depth D2 from the opening 20a side of the box body 20 to the inside of the back surface 20b.

When the drop bar 21 is set in the box body 20 and the slide block 23 is fitted in the box body 20, the slide block 23 is opened in the box body 20a.
To the rear surface 20b, the housing 20 can slide in a direction parallel to the rear surface 20b.

As shown in FIG. 6, when the gate main bodies 3 and 4 are closed, the engaging member 12 engages with the hook 13,
The drop bar 21 descends and its lower end has a hole 1 formed in the ground 15.
It fits in 6. In this case, the slide block 23 is, for example, as shown by the phantom line in FIG.
It is fitted in the lower recess of the recesses 20h provided in b. In this case, the spring 24 is housed in the horizontal hole 23c of the slide block 23, one end of the spring 24 is in contact with the outer periphery of the body 22b of the round head screw 22 and the other end is in contact with the inner part of the horizontal hole 23c. Therefore, the slide block 23 is always urged toward the rear surface 20b, and therefore the rear end of the slide block 23 does not come out of the recess 20h.

When the gate main bodies 3 and 4 are opened, for example, the grip 9 is operated to remove the engaging member 12 from the hook 13 and the grip 9 is pulled to open the gate main body 4 around the hinge 6. When the gate main body 4 is opened, the surface of the vertical member 3a of the gate main body 3 facing the vertical member 4a of the gate main body 4 is opened, and the slide block 23 is exposed. Therefore,
When the protrusion 23d of the slide block 23 is pinched from above and below with the fingers and the slide block 23 is pulled toward the opening 20a side of the box body 20, the slide block 23 overcomes the resistance of the spring 24 and moves toward the opening 20a side of the box body 20. It moves while sliding on the inner part of 20, and the box body 2 of the slide block 23.
The rear end on the back surface 20b side of 0 is separated from the recess 20h.

The rear end of the slide block 23 is a recess 20h.
When the slide block 23 is detached from, the slide block 23 is moved upward while holding the slide block 23 with a finger. Then, the drop bar 21 also rises together with the slide block 23, and the lower end of the drop bar 21 separates from the hole 16. Therefore,
When the finger is released from the slide block 23, the slide block 23 is moved by the force of the spring 24 to the rear surface 20 of the box body 20.
It is moved to the b side, and the rear end fits into one of the upper recesses 20h. In the case of FIGS. 1 and 2, the rear end of the slide block 23 is fitted in the uppermost recess 20h.

When the drop bar 21 is raised, the slide block 23 is guided by the inner side surface of the box body 20 to move up, and the drop bar 21 is guided to the inner peripheral portion of the hole 20g.
1 can be raised smoothly.

If the rear end of the slide block 23 is fitted into the recess 20h of the rear surface 20b of the box body 20 with the lower end of the drop bar 21 separated from the hole 16, the lower surface of the rear end of the slide block 23 becomes the slide block 23. The rear end of the protrusion engages with the upper surface of the protrusion 20c below the recessed portion 20h,
Since the drop bar 21 is supported by the slide block 23 and the lower end of the drop bar 21 is kept separated from the hole 16, the gate body 3 can be opened around the hinge 5.

When the gate main bodies 3 and 4 are closed and the lower end of the drop bar 21 is fitted in the hole 16 of the ground 15, the slide block 23 faces the vertical member 3a of the gate main body 3. Since it is hidden by the vertical member 4a of the gate body 4, the slide block 23 cannot be operated,
Therefore, the drop bar 21 cannot be raised via the slide block 23.

Further, since a part of the drop bar 21 is exposed between the lower end edge of the gate main body 4 and the ground 15, even if an attempt is made to pinch this exposed part with a finger and raise the drop bar 21. ,
The upper surface of the rear end of the slide block 23 is the slide block 2
When the rear end 3 of the door 3 is engaged with the lower surface of the projection 20c above the recess 20h in which it is fitted, and therefore the gate bodies 3 and 4 are closed, the drop bar 21 cannot be raised.

As described above, in this embodiment,
When the gate bodies 3 and 4 are closed, the drop bar 21 is inserted into the hole 16
Since it cannot be disengaged from the door, the closed gate bodies 3 and 4 do not open naturally, which is advantageous for crime prevention.

Further, even if the ground 15 is inclined, the rising position of the drop bar 21 can be adjusted at fine intervals by the tilt of the ground 15, so that it is not always necessary to raise the drop bar 21 to the uppermost position. Is easy.

When closing the gate main bodies 3 and 4, first, while the gate main body 3 is closed, the slide block 23 is guided downward to the box body 20 while the slide block 23 is pulled toward the opening 20a by a finger. It slides, the drop bar 21 is lowered through the slide block 23, and its lower end is placed on the ground 1.
5, the gate body 4 is closed, and the operating member 11 is operated to engage the engaging member 12 with the hook 13.

The present invention is not limited to the above-mentioned embodiments, and it goes without saying that various modifications can be made without departing from the gist of the present invention.

[0033]

According to the gate of the present invention, since the drop bar cannot be lifted when the gate body is closed, the closed gate body does not open naturally, which is advantageous in crime prevention. Also, the amount of raising the drop bar when opening the gate can be adjusted according to the level of the ground, so even if the ground is inclined, it is possible to easily perform various excellent effects. Can play.
