Description

[Detailed description of the invention] The present invention relates to a latch device for a cylinder lock in which the latch slides, and has been improved so that the latch can be easily set in the correct positional relationship with the cylinder lock without being limited by its size. It is.

The conventional latch sliding type cylinder lock device is
A sliding part is provided at the tip of the outer cylinder of the cylinder lock, and the latch is slidably attached directly to this sliding part, so the width of the latch may vary depending on the original structure of the cylinder lock and standard dimensions. The size of the latch is largely regulated, and the flexibility of being able to use a latch of any size is lacking.
In addition, due to the structure that is attached directly to the cylinder lock,
The problem is that the installation work is troublesome and requires skill.

Therefore, the present invention uses a frame to attach the latch, and by slidably inserting the latch into the frame, the latch can be positioned by itself.
The latch device is configured so that the correct engagement relationship between the operating pin on the cylinder lock side and the latch can be maintained immediately by inserting and supporting the cylinder lock into the front plate connected to the frame body, which improves the above-mentioned conventional device. This completely solves the problem.

That is, the latch device for a cylinder lock, which is a feature of the present invention, will be explained with reference to the embodiment shown in the attached drawings. A frame body 5 having a front plate 4 is formed, and sliding holes 8 and 9 having different lengths are formed on a pair of opposing plate surface portions 6 and 7 on either the upper, lower, left or right sides of the frame body 5, respectively. A latch 11 is slidably inserted into both the sliding holes 8 and 9 toward the shorter sliding hole 9 than the longer sliding hole 8. The part 13 can be freely locked onto the edge of the shorter sliding hole 9, while the frame 5 is attached to the back surface of the attached part 1.
The cylinder lock 21 is inserted into the mounting holes 2 and 3 to support the front plate 4 of the cylinder lock 21, and the operating pin 24 rotatably attached to the tip of the cylinder lock 21 is supported. Above latch 11
In the illustrated case, upper and lower plate surfaces are used as a pair of opposing plate surfaces 6 and 7; Of course, a surface portion may also be used.

In the above configuration, the mounting hole 2 and the mounting hole 3 have recesses 2 into which the positioning protrusions 23 protruding from the outer cylinder 22 of the cylinder lock 21 are fitted.
a and 3a are provided, respectively, so that the mounting position of the cylinder lock 21 can be determined. The front plate 4 is formed in a size that covers the open front part 5a of the frame body 5, and is connected to the frame body 5 with a gap formed between it and the front part 5a in which a bifurcated stopper piece 14 can be attached. ing. This stopper piece 14 is made of a spring plate, and is fitted into the outer cylinder 22 of the cylinder lock 21 on the back side of the front plate 4, and its strong spring force causes the cylinder lock 21 and the attached part 1 to be connected to the front plate. 4. Strongly connect the three parties. Cylinder lock 21
Both leg rods 14a of the stopper piece 14 are mounted on the outer cylinder 22 of the
A groove 22a into which the holder is fitted is provided.

Next, the operating configuration of the operating pin 24 attached to the cylinder lock 21 side will be explained.

A part of this operating configuration is conventionally known, but a slight gap is formed at the distal end of an inner cylinder (not shown) rotatably provided in the outer cylinder 22 of the cylinder lock 21, and the operating disc is 25 is fixed by means of rivets 26, and a rotary plate 27 is rotatably mounted between the actuating disk 25 and the end surface of the inner cylinder. A pressing protrusion 25a is provided on the periphery of the operating disc 25, with a part thereof protruding, and on the other hand, the above-mentioned operating part is provided on the rotating plate 27 at a portion far away from the center of rotation of the rotating plate 27. A pin 24 is provided protrudingly, and
An engaging protrusion 28 is provided on the movement path of the protrusion 25a. Further, two locking portions 27a, 2 are provided on the circumference of the rotating plate 27 with an appropriate gap.
7b, and these locking portions 27a, 27b are alternately engaged with a stopper (pin) 29 protruding from the tip of the outer cylinder 22 of the cylinder lock 1 by rotating the rotating plate 27 in the forward and reverse directions. The mechanism is such that the rotation angle is regulated.

That is, when a key (not shown) is inserted into the keyhole 21a of the cylinder lock 21 and the inner cylinder is rotated, the actuating disk 25 rotates and the rotating plate 27 is pressed by one end of the pressing protrusion 25a. The engagement protrusion 28 is pressed (see FIG. 2B), and this pressing action causes the rotation plate 27 to
is rotated until one of the locking portions 27a hits the stopper 29 (see FIG. 2C), and
When the actuating disk 25 rotates in the opposite direction at this rotation stop position, the rotating plate 2
The engaging protrusion 28 of No. 7 is pushed in the opposite direction from the front, and this pressing action causes the rotating plate 27 to engage the other locking portion 27.
b will rotate until it hits the stopper 29 (see Figure 2 A). Therefore, the rotation of the rotating plate 27 in the forward and reverse directions causes the operating pin 24 to rotate in the forward and reverse directions by a predetermined angle, thereby allowing the latch 11 to slide up and down in the drawing.

The present invention is as described above, in which the latch is inserted into the sliding holes provided oppositely to each other in the frame, and the stepped portion formed in the latch allows the latch to be inserted into the shorter side of the frame. When the cylinder lock is temporarily locked on the edge of the sliding hole and attached to the frame through the mounting hole provided on the front plate, the operating pin on the cylinder lock side can immediately engage the engagement groove provided on the latch. Since this structure has been adopted, the positioning of the latch can be determined correctly when it is inserted into the frame, and it can easily engage with the actuating pin, and it goes without saying that special skill is not required for the installation work. This makes it possible to use a latch of any size depending on the part to which it is attached, without being restricted by the standard dimensions of cylinder locks. In addition, since the latch mounting body is formed as a frame with a front plate that is joined to the part to be mounted, it can be assembled without the need for other mounting hardware such as screws, greatly reducing the number of parts. Coupled with the advantage that it can be applied to various doors and drawers, such as being able to reduce costs, its practical value is extremely great.
