Abstract

(57) [Summary] [Purpose] To reverse the rotation direction of the handle and the stopper plate so that the stopper plate can be stably held in the locked position by its own weight. [Structure] A support shaft 11 of a handle and a support shaft 6 of a stopper plate 5 are provided separately from each other in the vertical direction of the door, and the rotation of the handle is transmitted to the stopper plate 5 via a cam plate 19 to rotate the direction of rotation. Reverse.

Description

[Detailed description of the device]

 [Purpose of device]

[0001]

[Industrial applications]

 The present invention relates to a door lock handle that rotates a stopper plate by rotating a handle attached to a door.

[0002]

[Prior art]

 For example, a door provided on the front surface of the distribution box so as to be openable and closable is provided with a handle and a stopper which is pivotally driven by the rotation of the handle and whose tip is engaged with and disengaged from the frame of the distribution box. The base end of this stopper plate is conventionally fixed to the support shaft of the handle. Therefore, the turning direction of the handle and stopper plate was the same direction.

[0003]

[Problems to be solved by the device]

 According to the conventional door lock handle configured as described above, the handle is normally held in the state of being lowered in the vertical direction about the support shaft, and the stopper plate is horizontal and locked to the frame of the box. Then, by rotating the handle, the stopper plate is rotated downward to release the engagement with the frame body. For this reason, when the weight of the stopper plate is heavy, the force is always applied in the direction to release the lock, and the stopper plate may rotate under its own weight without releasing the handle, and the lock may be released. was there.

In order to solve this problem, the stopper plate may be rotated upward when releasing the locking, but for this purpose, the handle must be rotated to the outer peripheral side of the door. , The handle projects outside the box. Therefore, in the case of a double door, there is a problem that it is difficult to open the door due to interference between the handles. In addition, in order to prevent the interference of the handle, the handle must be installed at a position away from the peripheral edge of the door, which causes a problem in appearance.

The present invention has been made in view of the above points, and provides a door lock handle capable of preventing the stopper plate from rotating when the door is closed and securely locking the door by the stopper plate. The purpose is to [Device configuration]

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a door lock handle having a handle rotatably supported by a door, and a latch which is driven to rotate in association with the rotation of the handle. The support shaft of the handle and the support shaft of the stopper are rotatably attached to the door in the vertical direction, and the pair of support shafts are slidably engaged with each other. A cam plate having a hole and second and third elongated holes formed at right angles to both sides of the first elongated hole is provided, and the tip of the arm fixed to the support shaft of the handle is provided. Pins that engage with the second and third elongated holes formed in the cam plate are planted at the base end side of the stopper plate and the stopper plate, respectively, and the turning directions of the handle and the stopper plate are reversed. It was done like this.

[0007]

[Action]

 According to the above structure, the cam plate is slidably guided by the respective support shafts of the handle and the stopper plate through the first elongated hole and moves up and down. By rotating the handle, the cam plate rises through the third elongated hole by the pin implanted in the arm. As a result, the pin implanted on the proximal end side of the stopper plate rises through the second elongated hole, and the stopper plate rotates in the direction opposite to the handle to unlock the door.

According to this structure, the stopper plate is always in the locking position of the door due to its own weight, and the door can be prevented from opening due to external force.

[0009]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

1 to 5 show an embodiment of the present invention. In FIG. 2, a positioning plate 2 is fixed to the door 1 by four screws (not shown). The positioning plate 2 is formed of an oblong plate as shown in FIGS. 3 and 4, and four mounting holes 3 are provided on the center line. A cylindrical stopper plate 4 is vertically welded and fixed to the upper part of the positioning plate 2. A support shaft 6 of a first stopper plate 5 is rotatably supported on the seat 4, and a first stopper plate 5 is attached to the tip of the support shaft 6 as shown in FIGS. 1 and 2. It is fixed by a bolt 9 through a hole washer 7 and a square washer 8.

On the other hand, the positioning plate 2 is formed with a hole 12 through which a support shaft 11 of the handle 10 passes, and the support shaft 11 is rotatably supported by the positioning plate 2 via a seat 13. A second stopper plate 14 as an arm is fixed to the tip of the support shaft 11 by a bolt 17 via a washer 15 and a square hole washer 16. The second stopper 14 is formed in a substantially T shape, and mounting holes 18 to which locking rods (not shown) are connected are formed near both ends of the bottom side.

A cam plate 19 as shown in FIG. 5 is provided in parallel with the positioning plate 2, and a first elongated hole 20 is formed in the longitudinal direction at the center of the cam plate 19. Further, on the cam plate 19, a second elongated hole 21 is formed on the upper side and a third elongated hole 22 is formed on the lower side on both sides of the first elongated hole 20 in a direction perpendicular to the first elongated hole 20. ing. A washer 7 mounted on the support shaft 6 of the first stopper 5 and a washer 15 mounted on the support shaft 11 of the handle 10 are slidably engaged with the first elongated hole 20, respectively. ing.

A first pin 23 is planted in the vicinity of the base end on the opposite side to the locking end of the first stopper 5 and a first pin 23 is provided in the vicinity of the top of the second stopper 14. Two pins 24 are planted. The pins 23 and 24 are slidably engaged with a second long hole 21 and a third long hole 22 formed in the cam plate 19, respectively.

Next, the operation of this embodiment will be described with reference to FIG. When the handle 10 is rotated in the arrow A direction, the second stopper plate 14 fixed to the support shaft 11 also rotates in the arrow A direction. As a result, the locking rod (not shown) connected to the mounting hole 18 moves up and down to release the lock with the frame of the box (not shown). When the second stopper 14 rotates in the direction of the arrow A and reaches the position shown by the chain double-dashed line, the cam plate 19 is pushed down via the second pin 24 and the first pin 23 to the first position. The stopper 5 of 1 rotates in the direction of arrow B. As a result, the locking end of the first clasp 5 moves to the position shown by the chain double-dashed line, and the locking with the frame body (not shown) is released.

According to this embodiment, since the turning direction of the handle 10 and the turning direction of the first stopper plate 5 are opposite to each other, the handle 10 is turned in the direction of arrow A which is separated from the peripheral edge of the door 1. By doing so, it is possible to raise the first stopper plate 5 and release the lock. Therefore, when the closed state of the door 1 is maintained by the first stopper plate 5, the first stopper plate 5 can be lowered and hold its position by its own weight, and the door 1 can be prevented from being released. it can.

In the above embodiment, the case where the door 1 is locked by the first stopper 5 and the second stopper 14 has been described, but the lifting and lowering of the locking rod by the second stopper 14 is omitted. I don't mind. In this case, the second stopper 14 simply serves as an arm as a driving means for moving the cam plate 19 up and down.

[0017]

[Effect of device]

 As described above, according to the present invention, since the handle and the stopper plate are rotated in the opposite directions, the stopper plate is stably placed in the locking position without protruding the handle to the outside of the door. Can be held.
