BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gate lock used for a gate of various facilities such as houses.

[0002]

2. Description of the Related Art Generally, a conventional gate lock is composed of an arm that moves up and down by operating a handle of the door, an arm receiver for receiving the arm, a thumb turn for locking and unlocking with a finger, and the like.

[0003]

By the way, in the above-mentioned conventional gate lock, the arm member returns to the horizontal position when the hand is released. Therefore, when the door is closed, the lever is operated to raise the arm once. After passing through the arm receiver, it was necessary to lower it again and tighten it dry. For this reason, there is a drawback in that the arm member cannot be closed by simply closing the opened door, and the door cannot be closed when both hands are blocked by luggage or the like.

SUMMARY OF THE INVENTION An object of the present invention is to provide a gate lock which has been made in view of the above-mentioned drawbacks and which does not require a lever to be operated to move an arm up and down when the door is closed.

[0005]

The gate lock according to the present invention is:
A lever member for opening and closing the door, and the arm member is rotated is connected to the lever member receives the arm member at a predetermined position, the gates tablet comprising a receiving member that abolish lock the door, the arms A coil spring and an arm pin support the member so that it can be tilted with respect to the rotation surface, and the arm pin falls when it is rotated upward by a predetermined angle.
The arm is tilted with respect to the turning surface and is raised
It is characterized by having an engaging hole for holding a material .

[0006]

As described above, according to the gate lock of the present invention, when the door is closed, the lever can be manually operated to close the arm member without moving up and down.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to the accompanying drawings. The gate lock 10 includes a lever member 11 for opening and closing a door, an arm member 12 that is connected to the lever member 11 and is rotated, a receiving member 13 that receives the arm member 12 at a predetermined position, and a rotation of the arm member 12. An arm shaft 17 that includes a lock mechanism 14 that prevents movement, and that pivotally supports the arm member 12 by a coil spring 15 and an arm pin 16 so as to be tiltable with respect to a rotating surface, and the arm pin 1.
It has an engagement hole 18 which is depressed when 6 rotates by a predetermined angle. Here, the arm member 12 is formed in a substantially L shape in which the tip 12a is bent in a hook shape, and is supported by the arm shaft 17 at the base end so as to be tiltable by a pin 19. An arm pin 16 is fixed to the arm member 12.
The receiving member 13 is formed in a U-shaped cross section and has a hole 13
A and 13b are fixed to the door with screws or the like. Arm axis 1
As shown in FIGS. 9 to 11, the reference numeral 7 is composed of a substantially prismatic tip portion 20 that supports the arm member 12, a flange portion 21 and a base end portion 22 into which the spindle shaft is inserted. Tip 20
The pin hole 20a into which the pin 19 is inserted is formed in the. Further, the collar portion 21 has an inclined surface 21a with the axis of the pin hole 20a as a boundary, and the coil spring 1
5, a blind hole 23 for inserting 5 and a through hole 24 for inserting the arm pin 16 are formed.

The lock mechanism 14 is composed of a thumb turn 25, a cam plate 26 slid by the thumb turn, a lock plate 28 having a recess 28a into and from which an operating portion 26a provided at the tip of the cam plate 26 is inserted and removed. Has been done. Cam plate 26
Has an actuating portion 26a at the tip and an elongated hole 26b at the center, and the pin of the thumb turn 25 is loosely fitted in a recess 26c provided in a part of the elongated hole 26b. Sam Turn 25
It has a knob 25a, a circular flange 25b, and a pin 25c for sliding the cam plate 26. Also, the lever member 11
Is inserted into the recess of the arm shaft 17 via a spindle shaft (not shown).

Next, a method of using the gate lock configured as described above will be described. First, when opening the door,
As shown in FIGS. 8 and 19, the lever member 11 is twisted so that it is slightly tilted from the horizontal. Then, the arm member 12 rises from the engaged state shown in FIG. 1 by a predetermined angle as shown in FIGS. 5 and 6, is disengaged from the receiving member 13, and the door can be opened.
When the arm member 12 rises by a predetermined angle, the arm member 12
The arm pin 16 erected on the bottom of the arm falls into the engaging hole 18.
At this time, since the arm member is always biased by the coil spring 15 in the direction of arrow A in FIG. 4, the arm pin 16 easily falls into the engagement hole 18. Arm pin 16
When is dropped into the engaging hole 18, the arm member 12 rises by this predetermined angle and maintains a state of being inclined with respect to the rotating surface.

Next, the case of closing the door will be described. When the arm member 12 is raised by a predetermined angle and comes into contact with the other door, the arm pin 16 is pushed out in the direction of the arrow B in FIG. When the arm pin 16 slips out of the engagement hole 18, the arm pin 12 engages with the receiving member 13 of the mating door due to the weight of the arm member 12 or a spring force (not shown), and the empty tightening is completed. When locking the door, thumb turn 25
To operate. When the thumb turn 25 is operated, as shown in FIGS. 7 and 8, the cam plate 26 engaged with the pin 25c rises,
It fits into the recess 28a of the lock plate 28. When the lock plate 28 is locked, the arm shaft 17 and the arm member 12 engaged with the lock plate 28 are fixed and locked.

When the thumb-turn 25 is unlocked, if the thumb-turn 25 is rotated in the opposite direction, the actuating portion 26 of the cam plate 26 is unlocked.
a is disengaged from the lock plate 28, and the arm shaft 17 and the arm member 12 can freely rotate. The present invention is not limited to the above embodiments, and various design changes can be made based on the technical idea of the present invention.

[0012]

As described above, according to the gate lock of the present invention, the lever member for opening and closing the door, the arm member connected to the lever member and rotated, and the arm member are predetermined. receiving at the location, the gates tablet comprising a receiving that abolish lock the door member, by the arm members coil spring and the arm pin, an arm shaft for tiltably axially supported against rotation plane, the arm pin is a predetermined angle inclined with respect to write-rotation surface falls upon pivotally raised and elevated position
Since there is an engaging hole that holds the arm member in place, it is not necessary to operate the lever to move the arm member up and down when closing the door, simply close the door and make the arm member contact the receiving member.
Simply, the arm member automatically engages with the receiving member .
Therefore, the time and effort of opening and closing the door are greatly reduced, and even if the luggage is held in both hands, it can be easily opened and closed.
