Description

[Detailed description of the invention] This invention is installed on a sliding type safe door installed at the entrance of a safe, and can automatically brake the safe door in the open and closed positions. The present invention relates to a braking device for a sliding safe door that allows the braking device to be easily released when the door is moved.

The configuration of the present invention will be explained in detail below with reference to illustrated embodiments.

A through hole 2 leading from the outside of the safe to the inside of the safe is bored in the approximate center of the door body 1, and an operating rod 3 is slidably inserted into the through hole 2 at the outer end of the operating rod 3. A compression spring 5 is wound between the push button 6 of the operation rod 3 and the door body 1, and a guide plate 7 is attached to the inner end of the refrigerator with a locking member 22 having a diameter larger than that of the operation rod 3. A press roller 4 is rotatably provided on the locking member 22.

The frame body 8 in which the door body 1 is housed is hung on the left and right sides of the upper part to form a U-shaped cross section, and a brake hole 10 is bored through which the brake lever protrudes at the door opening and closing positions of the door body 1. A brake plate 9 is provided, and an inverted trapezoidal push plate 11 having a slope 23 toward the door body 1 is fixed to the brake plate 9 and the brake plate 9 on the side of the door closing stop position of the door body 1.

A rotating rod 12 is rotatably attached to the door body 1 by a shaft 24, and a push shaft 1 is attached to one end of the rotating rod 12.
3 is slidably supported on the door body 1 by a support plate 33, biased upward by a spring body 32, and rotatably provided by a shaft 25, and a roller 14 is rotatably provided at the upper end of the shaft 13. A wire 15 is connected to the other end of the rotating rod 12, and a spring body 16 is connected to the end of the wire 15.

The U-shaped ratchet 17 holds the locking member 22 and is pivoted to the mounting plate 34 of the door body 1 through a shaft 26, and the spring body 1 is attached to one side of the ratchet 17.
6 are joined together, and a spring body 18 is stretched between the other piece and the mounting plate 34 of the door body 1.

An L-shaped brake lever support plate 28 having a round hole is fixed to the approximate center of the door body 1.
The brake rod 27 is inserted into the round hole 8 so as to be slidable up and down, the retaining ring 29 is fitted approximately in the center of the brake rod 27, and a spring is inserted between the bent portion of the brake rod support plate 28 and the retaining ring. A concave locking member 30 is fixed to the upper end of the brake rod 27, a roller 20 is rotatably provided in the recess of the locking member 30, and the presser roller is attached to the lower end of the brake rod 27. A contact member 19 having a slope 31 pressed by the contact member 19 is provided.

Next, the operation of the braking device for the sliding door of the present invention will be explained with respect to the illustrated embodiment according to the above-described configuration of the present invention.

First, the operation from the closed door state to the open door state will be explained. When the door body 1 is closed, the roller 14 provided at one end of the rotating rod 12 comes into contact with the push plate 11, and the rotating rod 12 rotates clockwise, causing the wire 15 and the spring body 16 to The ratchet 17 is biased counterclockwise.

At this time, when the push button 6 is pushed into the inside of the refrigerator, the operating rod 3
is slid inward against the spring body 5, and at the same time the presser roller 4 is pivoted on the tip of the operating rod 3.
presses the slope 31 of the contact member 19, and the brake rod 27 is separated from the brake hole 10 of the brake plate 9. Also, the lower piece of the ratchet 17 is the locking member 2 of the operating rod 3.
2 to maintain the pressed state of the operating rod 3,
Furthermore, the door body 1 can be opened by maintaining the depressed state of the brake rod 27 by the operation rod 3.

When the door body 1 is moved in the door opening direction and the roller 14 is separated from the push plate 11 and released from the pressing force, the rotation rod 1
2 is rotated counterclockwise by the biasing force of the spring body 32, and at the same time, the latch 17 is rotated clockwise by the biasing force of the spring body 18. The engagement with the lever 3 is released, the operating lever 3 is slid to the outside of the refrigerator by the biasing force of the spring body 5, the push button 6 is made to protrude, and the brake lever 27 is also pushed down by the roller 4 pivoted on the operating lever 3. The roller 20 provided at the upper end of the brake rod 27 is released due to the biasing force of the spring body 21.
is brought into contact with the brake plate 9, and when the door body 1 is moved to the door opening stop position, the brake rod 27 is brought into contact with the spring body 21.
The urging force causes the brake plate 9 to protrude from the brake hole 10 at the door opening stop position, thereby braking the door body 1.

Next, the operation from the open state to the closed state will be explained.

When the push button 6 is pushed into the inside of the refrigerator, the operating rod 3 is slid toward the inside of the refrigerator against the spring body 5, and the presser roller 4 pivoted on the tip of the operating rod 3 moves against the contact member 19.
The brake lever 27 is released from the brake hole 10 of the brake plate 9 by pressing the slope 31 of the brake lever.

At this time, the ratchet 17 is biased clockwise by the biasing force of the spring body 18, and the upper piece of the ratchet 17 engages with the locking member 22 of the operating lever 3 to maintain the pushed state of the operating lever 3. , and further maintains the depressed state of the brake rod 27 to open the door body 1.
It becomes possible to close the door.

When the door body 1 is moved in the door closing direction and the roller 14 pivoted on the rotating rod 12 is brought into contact with the push plate 11, the rotating rod 12 is rotated clockwise,
The ratchet 17 is rotated counterclockwise by the wire 15 and the spring body 16 connected to the rotating rod 12, and the engagement with the locking member 22 of the operating rod 3 is released, and the operating rod 3 is released from the spring body. It is slid to the outside of the refrigerator by the urging force of 5.

At this time, the presser roller 4 pivoted to the inner end of the operating rod 3 is separated from the contact member 19 provided at the lower end of the brake rod 27, and the brake rod 27 is pushed upward by the urging force of the spring body 21. The roller 20 is brought into contact with the brake plate 9, and when the door body 1 is further moved to the closed stop position, the roller 20 is brought into contact with the brake plate 9.
The door body 1 is completely braked by protruding from a brake hole 10 formed in the hole.

As detailed above, the sliding door braking device according to the present invention can easily open and close the door by simply pressing the push button, and the braking device automatically operates when the door opening and closing operations are completed to secure the door body. The purpose of the present invention is to provide a braking device for a sliding door which has a simple structure and is very easy to operate, and which satisfactorily achieves the intended purpose.
