[Industrial applications]

 The present invention relates to a gate lock device in which a free end side gate is rotatably connected to an end of a gate post side gate.

[0002]

[Prior Art]

 FIG. 1 is a plan view showing a gate (commonly known as a double gate) in which a free-end side gate is rotatably connected to an end of the gate-post side gate together with a single gate.

Reference numerals 11 and 12 are left and right gate posts, and 13 is a single gate door that is rotatably connected to one of the gate posts 11 by a hinge 14. Reference numeral 15 is a gatepost side gate that is also rotatably connected to the other gatepost 12 by a hinge 16, and 17 is a free end side that is rotatably connected to the gatepost side gate 15 by a hinge 18. It is a gate, and the gate 15 on the pillar side and the gate 17 on the free end side form a double gate. In such a double gate, at least a first lock 19 is attached below a hinge (shaft) 18 connecting the gate-side gate 15 and the free-end side gate 17. A second drop lock 20 similar to the first drop lock 19 is also attached to the lower part of the free end side gate 17 or the single gate 13.

By the way, in the conventional drop lock 19, as shown in FIGS. 2 and 3, a drop bar holder 191 is fixed to the lower part of the inner side surface of the gate post 15 or the free end gate 17, and the drop bar is held. The drop bar 192 is inserted into the holes of the insertion parts 1911 and 1912 provided on the upper and lower sides of the tool so that the drop bar 192 can be raised and lowered. When locking the gate after closing the gate, rotate the knob / stopper 193 with your finger to align the knob / stopper with the notch in the upper insertion portion 1911 and then remove the knob / stopper 193. When dropping it by its own weight or pushing it down by hand to operate it so that the lower end of the drop bar 192 is dropped into the hole of the receiving tool 21 provided on the road surface, and when unlocking before opening the gate, , Similarly, by grasping the knob / stopper 193 with a finger and lifting the drop bar 192, the lower end portion of the drop bar 192 is lifted from the metal fitting 21, and the knob / stopper is passed upward through the cutout portion of the upper insertion portion 1911. The knob / stopper 193 is operated so as to rotate to a required angle so as to be locked by the upper insertion portion 1911.

[Technical issues to be solved]

 As described above, the conventional drop lock is troublesome because it is necessary to bend the body and turn the drop bar by hand each time the gate is opened and closed. It was very inconvenient especially when carrying baggage and during rainfall.

[0006] The present invention has been made in view of the above points, and provides an operation-free lock device for a gate, which automatically moves a drop bar up and down in conjunction with opening and closing of the gate. The purpose is to do so.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, a gate lock device according to the present invention is provided with a drop bar holder provided with a spiral guide hole having a rotation angle of 180 ° or less, which communicates with the inside and outside of the cylinder. Align the axis of the part with the pivot of the double gate and attach it to the gate-post side gate, insert the drop rod into the drop rod holder so that it can move up and down, and insert the operating pin provided on the drop rod from the guide hole. It can be raised and lowered so as to project outward, and the operating pin can be lowered toward the lower part of the guide hole by the weight of the drop bar or by a downward biasing member, and the drop bar serves as a receiving metal at the deployment angle of the gate. It is characterized in that it is lowered and locked, and when the gate is rotated in the folding direction, the operating pin is raised in the guide hole and the drop bar is raised to be unlocked.

[0008]

[Action]

 When the double gate is unfolded, that is, when it turns in the direction to close the gate, the operating pin becomes free, so the drop bar descends inside the tube and the operating pin turns along the guide hole. While descending to the bottom of the guide hole. Therefore, the lower end of the drop bar enters the receiving bracket of the road surface, and the operating pin approaches the inner surface of the free-end side gate while facing it.

When the double gate is folded, that is, when the double gate is rotated in the direction of opening the gate, the operating pin is pressed against the inner surface of the free end side gate and slides upward, and along the guide hole. Ascends, and at the same time, the drop bar comes off the bracket.

[0010]

【Example】

 Next, an embodiment of the present invention will be described with reference to FIGS.

Reference numerals 1 and 2 are a gate-post side gate and a free-end side gate, respectively, which form a double gate. Of course, these gates 1 and 2 are rotatably connected by a hinge 8.

In the present invention, the drop bar holder 3 is attached to the lower portion of the inner side surface of the gate 1 on the gate side by screwing 4 or other method. The drop bar holder 3 integrally includes a fixed portion 31 having an L-shaped cross section fixed to a gate and a tubular portion 32 formed at one end of the fixed portion separated from the gate. The center line of the tubular portion 32 is aligned with the axis 9 of the hinge 8. Further, the cylindrical portion 32 is formed with a guide hole 33 spirally connected from the upper portion to the lower portion around the outer peripheral surface on the side opposite to the gate-post side gate 1 at a rotation angle of approximately 180 ° or less. The guide hole 33 communicates the inside and the outside of the tubular portion 32. The rotation angle is a projection angle from the upper end to the lower end of the guide hole 33 on the horizontal plane, and when the free end side gate 2 is opened and closed, the rotation angle is about the axis of the hinge 8 relative to the gate post side gate 1. It is almost equal to the rotated angle.

The drop bar 5 is vertically movably inserted into the cylindrical portion 32 of the drop bar support. Further, one end portion of the operating pin 6 which is vertically pierced through the guide hole 33 is joined to the drop rod. The operating pin 6 is projected from the tubular portion 32 to the outside with a required length. When no external force is applied to this actuating pin, the drop rod 5 and its actuating pin 6 themselves drop the drop rod 5 inside the tubular part 32 and the stopper 5a provided at the upper end of the rod stops on the upper surface of the tubular part. The operating pin 6 can also be lowered to the lower end portion of the guide hole 33.

Even when the frictional resistance between the inner peripheral surface of the tubular portion 32 and the outer peripheral surface of the drop bar 5 or the frictional resistance between the operating pin and the guide hole increases due to, for example, rust or dust, the drop bar Also, in order to allow the operating pin to descend smoothly, an urging means such as a coil spring that always urges the drop bar downward may be provided.

With the above structure, after rotating the double gates 1 and 2 in the open position in the closing direction and rotating the gate-post side gate 1 to the closed position, the free end side gate is further expanded and rotated in the closing direction. Then, the actuating pin 6 located at the upper end of the guide hole 33 is released, so that the actuating pin 6 descends along the guide hole 33 according to the rotation angle of the gate, and thus the drop bar 5 also. The tube portion 32 is lowered. When the free end side gate 2 is completely closed, the lower end of the drop bar enters the drop hole 7a of the receiving metal fitting 7 located below, so that the drop lock is locked. Further, the operating pin 6 obliquely opposes and approaches the inner surface of the free end side gate 2 in the closed position.

On the other hand, when the free end side gate 1 is folded, that is, when the gate 1 is rotated in the direction of opening the gate, the inner surface of the gate 2 contacts the actuating pin 6 and moves it inside. Since it is pushed, the operating pin 6 is raised while being rotated along the guide hole 33. Therefore, when the drop bar 5 is lifted and the gate 2 is rotated to the required angle, the lower end of the drop bar 5 comes out of the drop hole 7a of the receiving fitting 7, so that the double gates 1 and 2 are completely opened. be able to.

[0017]

[Effect of the device]

 As described above, according to the drop lock of the present invention, when the free-end side gate is rotated in the closing direction after the gate-post side gate is rotated to the closed position, the drop bar descends in conjunction with this. As it fits into the metal fitting, the lock is automatically locked. Also, when the free end side gate is rotated in the opening direction, the drop bar ascends in conjunction with this and the drop lock is automatically unlocked. Therefore, no manual operation is required, and the lock is very convenient.
