Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a simple lock that is attached to a sliding door of an opening in a building and locks the sliding door.

<Prior Art> Generally, a pair of sliding doors is used that is slidably attached to an opening in a building and has a fitting frame that overlaps from front to back when the opening is closed.

When the sliding doors are locked, it is desirable to prevent wind and rain from entering. For this purpose, it is necessary that the rear end surface of the front fitting frame and the front end surface of the rear fitting frame are brought into close contact.

A simple lock for such a sliding door is one in which a male screw body or a hook body rotatably held in the front fitting frame is screwed or engaged with a female screw body or locked body fixed to the rear fitting frame. Conventionally, there are things that can be matched.

<Problems that the invention aims to solve> When locking or unlocking with conventional simple locks, it is necessary to move the male screw body or hook body back and forth from the rear end of the front fitting frame, and then rotate the lock. The operation required two movements: a forward and backward movement, and a rotational movement, and was cumbersome.

In view of the above, it is an object of the present invention to provide a simple lock that can lock a sliding door with a single action and can bring the rear end surface of the front fitting frame into close contact with the front end surface of the rear fitting frame.

<Means for Solving the Problems> The technical measures taken by the present invention to solve the problems of the prior art are characterized by the use of a pair of layers that are overlapped in the inside-outside direction and opened and closed by movement in the sliding direction. Among the sliding doors 13, 13, one fitting frame 1

The operating body 3 and the first operating body 1 are interlocked and connected by being inserted in a bridge-like manner. here 6
A spring 3 is wound around the support shaft 29 and engages the first operating body 1 and the rotation regulating piece 31 . This biases the upper end of the first operating body 1 in a direction to swing rearward about the support shaft 29, thereby preventing the operating body 3 from falling naturally.

When the locking body 14 is attached to the holder 6 described above, the small diameter step portion 17 of the locking body 14 is inserted into and engaged with the recess 58 of the first actuating body 1, so that the locking body 14 is attached to the first actuating body 1. Therefore, it is said to be in the state of moving furthest forward. At this time, the pulling portion 22 is attached to the mounting base 19.
The free ends of the T-shaped attracting portions 22 are oriented upward and downward. Further, the flat part 18 of the locking body 14 engages with the rotation regulating tongue piece 53, and the locking body 1

The guide shaft 60 of the first operating body 1 is located at the lowermost end of the second portion 47b of the guide hole 47.

11 and 12 show a state in which the operating body 3 is slid downward from the above state. When the operating body 3 is slid downward, the guide shaft 60 moves relatively upward within the second portion 47b of the guide hole 47 and reaches the lower end of the first portion 47a. Then, since the second portion 47b is inclined diagonally rearward and downward, the first actuating body 1 through which the guide shaft 60 is inserted
The lower end swings backwards around the support shaft. Then, since the small diameter stepped portion 17 of the locking body 14 is inserted and engaged between the recesses 58 at the lower end of the first actuating body 1, the locking body 14 is moved backward by the swinging of the first actuating body 1. do. This backward movement distance is a predetermined dimension determined by the longitudinal distance between the first portion 47a and the lower end of the second portion 42b of the guide hole 47. By this backward movement of a predetermined dimension, the pulling part 22 of the locking body 14 is moved toward the rear end surface of the board 20, that is, the front fitting frame 11.
It will be in a state where it protrudes by a predetermined distance from the rear end surface 11'.
In this state, the flat portion 18 of the locking body 14 also moves backward, and the engagement with the rotation regulating tongue piece 53 is released. Here, the lower end of the second operating body 2 comes into contact with the teeth 8 of the locking body 14, but the locking body 14 is not rotated.

Figures 13 and 14 are similar to Figures 11 and 12.
A state in which the operating body 3 is further slid downward from the state shown in the figure is shown. By sliding the operating body 3 downward, the guide shaft 60 moves toward the first portion 47 of the guide hole 47.
a relatively upwardly to reach the recess 48 at the upper end. In this case, since the first portion 47a is along the sliding direction of the operating body 3, the first operating body 1 does not swing. Further, since the guide shaft 60 engages with the recess 48 due to the elastic force of the spring 63, the operating body 3 does not slide even if the sliding door 13 is vibrated. Then, when the operating body 3 slides downward, the lower end of the second operating body 2 and the engagement window 51 engage with the teeth 8 of the locking body 14 to rotate the locking body 14 approximately 90 degrees. Due to this rotation of the locking body 14, the free end of the pulling portion 22 is turned sideways.

Then, when you slide the operating body 3 upward,
By the movement opposite to the above, the pulling portion 22 is retracted from the rear end surface 11' of the front fitting frame 11 again.

Next, the indoor lock operating tool 4 shown in FIGS. 30 to 32 will be explained. In the indoor lock operating tool 4, reference numeral 64 denotes a rectangular mounting plate that is mounted to the front end surface of the front fitting frame 11 with mounting screws 65, 65, and the through holes 66, 66 of the mounting screws 65, 65 and the knob guide hole 67 are connected to each other. It is installed through.

Reference numeral 68 denotes a plate-shaped operating body, which is integrally formed with an operating knob 69 on the front surface and an interlocking protrusion 70 on the rear surface.

Reference numeral 71 denotes a holding plate through which a guide hole 72 for the connecting protrusion 70 is provided. Then, attach the operating body 68 to the mounting plate 6.
4 and fixed to the mounting plate 64 with screws 73, 73, and the knob 69 and the connecting protrusion 70 are made to protrude from the respective guide holes 67, 72.

The connecting protrusion 70 is inserted into the connecting hole 46 of the operating body 3. This results in
By moving the operating knob 69 up and down, the operating body 3 can be slid up and down.

Next, the locked object 1 shown in FIGS. 33 to 35
5 will be explained. The locked body 15 has a rectangular plate shape and has a rectangular opening 33 in the center thereof. Further, 74 is a through hole for the outdoor lock operating tool.
Then, the locked body 15 is arranged so that the opening 33 is located at a position corresponding to the longitudinal movement axis of the locked body 14.
is a screw 34 along the front end surface 12 of the rear fitting frame 12,
34. Here, the rear part of the opening 33 of the rear fitting frame 12 is hollowed out and a recess 35 is formed.
It is said that Thereby, the pulling portion 22 can be freely inserted into and removed from the opening 33 by protruding and retracting from the rear end surface 11' of the front fitting frame 11.

As shown in FIGS. 39 and 40, the rear end surface 15' of the locked body 15 has left and right openings 3.
Cam surfaces 40, 40 are formed along the three peripheral edges. The cam surface 40 is bulged in a chevron shape from the rear end surface 15' of the locked body 15, and has a flat central portion. Thereby, when the attracting portion 22 rotates within the opening 33, it is guided above the center of the cam surfaces 40, 40.
In this case, since the protruding dimension of the pulling portion 22 from the rear end surface 11' of the front fitting frame 11 is regulated to a predetermined dimension, the locked object 15 will be relatively drawn toward the locking object 14 side. . Pulling part 22
The protrusion dimension from the rear end surface 11' of the front fitting frame 11 is,
The rear end surface 11' of the front fitting frame 11 and the rear fitting frame 1 are made to have a predetermined dimension corresponding to the bulging size from the rear end surface 15' of the locked body 15 at the center of the cam surface 40.
2 front end surface 12' can be brought into close contact with each other.

Next, the outdoor lock operating tool 5 shown in FIGS. 36 to 38 will be explained. The operating tool 5 is embedded in the rear fitting frame 12 with screws 76, 76, and 77 is a mounting flange that is inserted into the screw insertion hole 7.
8 and 78, and 79 is a cylindrical portion in which a well-known cylinder lock is housed. A square connecting rod 81 projects from the front end and rotates when a duplicate key is inserted and rotated through the keyhole 80 on the rear end surface. The connecting square rod 81 is connected to the feeding gear 3 of the operating body 3.
9 is fitted into the connecting square hole 42 through which it is relatively unrotatable. Thereby, when the square rod 81 is rotated using a duplicate key from outside, the feeding gear 39 is rotated. Then, the tooth portion 3 of the feed gear 39
9a engages with the engagement windows 49 of the operating body 3, allowing the operating body 3 to be slid up and down.

To lock using the simple lock 9 with the above configuration,
The operating body 3 is moved downward via the outdoor lock operating tool 5 or the indoor lock operating tool 4. Then, the first actuating body 1 causes the attracting portion 22 to move as shown in FIGS. 3 and 40.
As shown in the figure, it protrudes from the rear end surface 11' of the front fitting frame 11 and is inserted into the opening 33. When the operating body 3 further descends, the opening 33 is opened by the second operating body 2.
As the pulling part 22 rotates within the interior, the rear end surface 11' of the front fitting frame 11 and the front end surface 12' of the rear fitting frame 12 come into close contact with each other as described above.
It will be in the state shown in the figure. Furthermore, in this state, the sliding doors 13, 13 are restricted from sliding in the left-right direction due to the engagement between the pulling portion 22 and the locked object 15 via the cam surface 40, thereby locking the sliding doors 13, 13.

Thereby, the sliding doors 13, 13 can be locked, and the rear end surfaces 11' of the front fitting frames 11 and the front end surfaces 12' of the rear fitting frames 12 of the sliding doors 13, 13 can be brought into close contact.

Next, in order to unlock the door, if the operating body 3 is moved upward via the outdoor lock operating tool 5 or the indoor lock operating tool 4, the lock is unlocked by the above-mentioned reverse operation.

In the above embodiment, the simple lock 9 is shown attached to the sliding door of the entrance, but it may also be attached to the sliding door indoors, and the sliding door is not limited to one that slides left and right, but can also be used up and down. It may also be something that slides. In that case, the outdoor lock operation tool does not require a duplicate key with a cylinder lock inside.

Furthermore, in the above embodiment, the operation body 3 is slid by a vertical movement operation from the indoor side and by a rotation operation from the outdoor side. The operating body 3 may be slid by operation.

<Effect of the invention> According to the invention, the swing link 1 is moved by vertically sliding the vertical plate 43 provided on one of the fitting frames 11.
Since the locking body 14 is moved in and out and rotated via the rotating body 16, the simple lock can be locked and unlocked by simply sliding the vertical plate 43.

In addition, the cam surfaces 40, 40 provided on the engagement body 15
Since the locking mechanism presses both ends of the hook portion 22, the two fitting frames 11, 12 can be tightly brought into contact with each other when the door is locked, and the intrusion of wind and rain from between the fitting frames 11, 12 can be prevented.
