Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a lock in which a sickle lock is retracted.

[Conventional technology]

In a lock with a sickle lock that appears and retracts, a key inserted into the cylinder lock from outside is used to grasp the cylinder from indoors, and the sickle lock is rotated in and out by raising and lowering a slider.

[Problem that the invention attempts to solve]

When unlocking the door from inside the room, you have to go to the front door each time to operate the door, so there is a problem in that you cannot quickly unlock the door when you are working in the kitchen or from a long distance, for example.

[Means for solving problems]

In order to solve the above problems, this invention provides a rocking piece in the lock box whose tip faces the front plate and moves up and down in conjunction with the retraction and protrusion of the sickle lock. An upper through-hole and a lower through-hole are provided at the upper position where the rocking piece stops rising and the lower position where the swinging piece stops descending, respectively, and the above-mentioned upper through-hole and lower through-hole are provided in the vertical stile on the front side of the door frame. An upper through-hole and a lower through-hole are provided that match the window, and one end of the arc-shaped piece penetrates the upper through-hole and the lower through-hole so as to push up the swinging piece as the vertical stile rotates in the normal direction, and as it rotates in the reverse direction. A rotating body is provided that penetrates the lower through-hole and the lower through-hole so that the remaining end of the arc-shaped piece pushes up the swinging piece, and furthermore, the rotating body is driven forward and backward by remote control within the vertical stile, and A driving device is provided for returning and rotating the arcuate piece so that both ends thereof do not protrude from the upper and lower through holes.

[Effect]

When the rotary body is rotated in the forward direction while the drive device is operated by remote control, one end of the arc-shaped piece penetrates the upper through hole and the upper through window and pushes down the rocking piece.
The sickle lock sticks out and locks the door.

Also, when the rotating body is reversed while the drive device is operating, the remaining end of the arc-shaped piece penetrates the lower through-hole and the lower through-hole and pushes up the swinging piece, so the sickle lock retracts and unlocks. .

〔Example〕

In the figure, A is a type of lock in which the sickle lock 1 is made to appear and disappear by operation.

The lock A above is the lock box 2 installed at the tip of door a.
and a through hole 4 provided in the front plate 3 of this lock box 2.
The end of the lock box 2 is rotatably attached via a pin 5 whose both ends are supported on both sides of the lock box 2, and as the lock box 2 rotates clockwise in FIG. A sickle lock 1 that is inserted into the lock box 2, a tilting plate 7 whose lower part is rotatably attached via a pin 6 to the lower part of the lock box 2, and this tilting plate 7.
A long hole 9 is provided at the distal end of the sickle lock 1 so that the protruding shaft 8 protruding from the upper side surface penetrates and engages with the lock box 2.
A rotating plate 11 is rotatably attached to the upper part of the interior via a pin 10, and the tip of this rotating plate 11 and the tilting plate 7
It consists of a pin 12 and a long hole 13 provided to engage with the upper part of the slider 15, and when the slider 15 is slid up and down by a pick 14 that projects into the handle a' from the inside, the slider 15 projects from the back side of the slider 15. pin 16 and a long hole 17 provided at the end of the rotating plate 11.
The sickle lock 1 is rotated in and out by engagement with the cylinder lock 18, and from the outside, the key inserted into the cylinder lock 18 is rotated to slide the slider 15 through the engaged pinion 19 and the rack 20, and the sickle lock 1 is rotated in and out. It's designed to move.

Furthermore, a swinging piece 21 that projects toward the front plate 3 is provided in the middle of the tilting plate 7 .

Further, an upper through window 22 and a lower through window 23 are provided on the upper and lower sides of the front plate 3 sandwiching the swinging piece 21 .

In addition, in the vertical stile B located on the side of the door a, there is a through window 24 that matches the through hole 4 and into which the sickle lock 1 is fitted and locked.
An upper through hole 25 that matches the upper through window 22 and a lower through hole 26 that matches the lower through window 23 are provided, respectively.

Inside the vertical stile B, one end of the arc-shaped piece 27 penetrates the upper through-hole 25 and the upper through-hole 22 so as to push down the swinging piece 21 as the rotation is normal (clockwise in FIG. 1), and as the rotation is reversed, the arc-shaped piece 27 A rotating body 28 is provided so that the remaining end of the rotating body 27 pushes up the swinging piece 21 (as shown in FIG. 3) and penetrates through the lower through hole 26 and the lower through window 23.

The rotating body 28 is rotatably supported by a piece 29 projecting from the center between both ends of the arc-shaped piece 27 via a pin 30 .

Further, the rotating body 28 is provided with a drive device 31 that is remotely operated in a kitchen or the like to rotate the rotary body 28 back so that both ends do not protrude from the upper through hole 25 and the lower through hole 26 after being driven in the forward and reverse directions. .

In the illustrated case, the above drive device 31 is provided with drainoids 32 and 33 that operate by energization in the vertical stile B, and the slide iron cores 34 of the solenoids 32 and 33 and the piece 29 are connected via a rod 35. Although the rotating body 28 is rotated to return by the return of the iron core 34 by the spring, it may be driven by other methods.

〔effect〕

As mentioned above, according to the lock related to this invention,
By rotating the rotating body by remote control in a place away from the entrance, such as the kitchen, the sickle lock can be rotated in and out by pushing down or pushing up the swinging piece via the arc-shaped piece.

Therefore, you can lock and unlock the door without having to go to the front door each time.

In addition, both ends of the arc-shaped piece of the rotating body are prevented from protruding from the upper and lower through holes due to the return rotation after the operation of the rotating body, so collision with the door edge can be avoided. .
