JP6120332B2 - Locking device for wooden sliding door - Google Patents

Description

  The present invention relates to a lock device that also serves as a pull handle that prevents a sliding door such as a glass shoji from being opened unexpectedly. A wooden sliding door is used as a doorway, indoor doorway, window, veranda doorway or gate. Sliding doors include single sliding doors and sliding doors.

Conventional sliding door lock devices, as represented by Crescent, are often attached to the door butt side (single sliding door) or the summoning side (sliding door) with respect to the door stop that is the part that opens and closes the sliding door. (Patent Document 1). Further, there is also proposed a locking device that also serves as a pulling handle that can be opened and closed when the lever is operated at the same time as holding the pulling handle on the door-stop side, and when the lever is operated, the latch is released. ).

  Furthermore, in a locking device incorporated in an open / close door such as a refrigerator or an automobile, the movement of the operation unit such as a handle for opening / closing operation is related to the operation of the lock device, and the lock is released when the operation unit is pulled, and the sliding door is opened as it is. There is something that can be done. For example, the “opening / closing door latch mechanism” of Patent Document 3 can operate the lever members (vertical portion 4 and horizontal portion 5) at the same time that the handle of the opening / closing door is gripped, and can be opened as it is. When the door is closed, the latch (the U-shaped groove 9 and the locking knitting 10) automatically functions. Such a structure is also a structure that can be seen in a handle of a pull-out cabinet having a latch lever on the back side (Patent Document 3).

  The above-mentioned prior art does not disclose a locking device that also serves as a pulling sliding door such as a broken glass shoji. The handle and lever of Patent Document 2 are operated at the same time, and the locked state is released by the latch mechanism. However, the handle is formed by digging into the surface of the sliding door or by providing a through hole, The lever is engaged. Such a structure is difficult to adopt for a fence with a narrow sliding surface. Further, the latch-locked and unlocked structure as shown in the cited document 3 is known as the basic structure for unlocking using the handle, but technical matters that can be adopted for the fence of the sliding door. There is no disclosure.

Also, for example, in the case of Kashigumi glass shoji, the shoji can not be opened and closed from the outdoor side if the summing part is locked with a crescent operated from the indoor side, but the crescent lock is small and the hand is cut out from the glass. Inserting and unlocking the crescent lock makes it easy to open and close. In addition, crescent locks and the like can only be expected to have a locking effect, and because there are no pulling handles on the sliding doors, when the door is closed, a finger is caught between the door-to-door fence and the opening frame of the building. Accidents cannot be prevented.
It is an object of the present invention to provide a locking device for a sliding door that can be opened and closed, locked, and unlocked in a stable manner and reliably at the door-stop side, and that can be opened and closed safely. Let it be an issue.

The locking device for the sliding door is constructed as follows. A pair of sliding doors is built on a sliding door frame attached to an opening of a building and opens and closes the opening.
The locking device includes a substrate, a puller, and a locking device. The puller is for opening and closing the door.
The pull handle includes a grip portion, an upper arm portion, and a lower arm portion. The puller is attached by fixing the heel side base portion of the arm portion to the substrate. At this time, an interval through which the back of the hand can pass is provided between the substrate and the grip portion.

The locking device is composed of a rotating plate and a receiving tool.
The rotating plate has a height that falls within a range of the height of the puller and can be rotated by the substrate and the hinge structure. The pivot axis of the hinge is arranged in the vertical direction.
Further, the rotating plate has an operating portion on the grip portion side of the handle and an engaging portion on the opposite side with respect to the rotating shaft of the hinge. The engaging portion is provided with an engaging claw. The rotating plate is always urged in a direction in which the operating portion is separated from the grip portion of the pulling handle by a spring provided in the hinge structure. Furthermore, the operation part is provided with an insertion hole through which the back of the hand can pass.

The receptacle includes a receptacle and a receptacle provided in the receptacle. The receiving opening is opened on the side of the receiving member facing the vertical side of the sliding door .
And the said board | substrate is fixed to the inner side finding surface of the door contact side vertical fence of a braided sliding door. As a result, the pulling plate and the rotating plate of the locking device are fixed to the door-holding vertical shaft.
The receiving device of the locking device is fixed to the inner surface of the vertical frame. The door stop side vertical frame is a vertical frame of the stile and the opposite side attached to the lock device of the sliding door frame Tatekomu the stiles set sliding doors. That is, the receiver is attached at a position facing the engaging claw on the rotating plate of the lock device.

  Therefore, when the braided sliding door is closed, the engaging portion of the rotating plate enters the inside from the receiving port of the receiving tool and is engaged with the receiving portion on the door-contact side. Thereby, it will be in a locked state. This operation is performed by the rotation of the rotating plate around the hinge axis of the hinge mechanism and the biasing of the spring, and the operating portion of the rotating plate is located away from the grip portion of the pulling hand.

  When you want to open the opening of the building, hold the pulling door of the sliding door together with the operation part of the rotating plate and pull it in the opening direction. In this operation, the action of grasping the grip portion of the pulling hand simultaneously rotates the operation portion of the rotating plate toward the grip portion, and releases the engaging portion of the rotating plate from the receiving portion. That is, the act of grasping the grip portion of the pulling hand to open the cocoon sliding door simultaneously becomes an unlocking operation, and the cocoon sliding door can be performed by one operation.

  In the structure of the locking device described above, the operation portion of the rotating plate in the locking device is always urged in the direction away from the grip portion of the handle by the urging force of the spring. If the door is inadvertently closed, the locking device is automatically locked as it is, and the person who goes outside is locked out and can return to the indoors again. In order to avoid such a closed state, a closing avoidance mechanism may be provided.

Since the act of grasping the grip portion of the puller is an unlocking operation at the same time, the sliding doors provided in the building opening can be opened simply by grasping and pulling the puller.
When closing the opening of the building, hold the pull handle and close the sliding sliding door. After the rotating plate rotates against the bias of the spring when the engaging part engages with the receiving part, Engage by returning and automatically lock.
Since the use of the hand pulling the opening and closing of the stile set sliding door, there is no worry on both sides of the finger between the door per side stile and the sliding door frame of the door per side vertical frame when closing.
Since the puller and the locking device are located in the same place, it is necessary to cut out the glass from the outside and operate it relatively large, and it takes time until the operation becomes possible. High nature.

The puller 16 is attached by fixing the flange side base portions 25a and 26a of the upper and lower arm portions 25 and 26 to the flat plate portion 18 of the substrate 15 by screwing or the like using the horizontally long holes 21a and 22a. At this time, an interval s1 through which the back of the hand can pass is provided between the substrate 15 and the grip portion 24 (FIG. 3). In FIG. 2, reference numerals 27 a and 27 b denote reinforcing members that are screwed between the lower surface of the base portion of the upper arm portion 25 and the substrate 15 and the upper surface of the base portion of the lower arm portion 26 and the substrate 15.

The locking device 17 includes a rotating plate 28 and a receiving tool 29 (FIG. 2).
The rotating plate 28 has a height that falls within the range of the height of the puller 16 and is assembled so as to be rotatable by the substrate 15 and the hinge structure 30. The rotating plate 28 is formed by pressing a single stainless steel plate, and includes a substantially rectangular operating portion 31 and an engaging portion 32 that protrudes from the center of the right side to the right and has a trapezoidal shape. The operation portion 31 is provided with an insertion hole 33 through which the back of the hand can pass, and an engagement claw 34 bent outward is provided on the right side of the engagement portion 32. Upper and lower rotation side stays 35a and 35b bent integrally to the indoor side are integrally provided at a location near the operation unit 31. The vertical dimension of the engaging claw 34 is smaller than the vertical dimension of a receiving port (described later) of the receiving tool 29.

  The hinge structure 30 includes the rotation-side stays 35a and 35b and the hinge base 36 (FIG. 2), the upper and lower hinge shafts 37a and 37b, and the upper and lower urging springs 38a and 38b of the engagement portion 32 of the rotation plate 28. It consists of. The hinge stand 36 is a vertically long rectangular plate that fits between the rotation side stays 35a and 35b, and is provided with support side stays 39a and 39b protruding upward and downward.

  The rotation-side stays 35a, 35b and the support-side stays 39a, 39b are overlapped on the upper and lower sides, and an urging spring 38a is disposed between the upper rotation-side stay 35a and the support-side stay 39a to rotate around the hinge shaft 37a. Similarly, the biasing spring 38b is disposed between the lower rotation side stay 35b and the support side stay 39b so that the rotation is possible with the hinge shaft 37b. Thereby, the hinge structure 30 which uses the common axis of the hinge shafts 37a and 37b as the rotation shaft 40 is configured.

That is, the rotating plate 28 is formed with the operating portion 31 on the grip portion 24 side of the pulling handle 16 and the engaging portion 32 on the right vertical shaft 7 side with the rotating shaft 40 of the hinge structure 30 as a boundary. The operating portion 31 side is always urged away from the grip portion 24 by the springs 38a and 38b. The rotation of the rotating plate 28 by the biasing springs 38a and 38b is restricted by a stopper piece 20 provided at the center of the substrate 15, and the rotating plate 28 stops at a fixed position until it is operated.
The receiving member 29 is a short rectangular tube-shaped member, and the side facing the right vertical gutter 7 is opened to form a receiving port 41. Inside the receiving port 41, there is a receiving portion 42 that winds the finding surface side wall of each cylinder inward and then rises at an angle toward the outdoor side.
In the locking device 14, the component 14 a displays the entire heel side member of the locking device 7, and the component 14 b displays the holder 29 of the locking device.
