Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a locking device for a sash, and in particular for a sliding window where the shoji is flush with each other when closed, by operating the locking handle of one shoji. This relates to a locking structure that causes the locking and unlocking operations of the other shoji together with that shoji.

[Prior Art] Conventionally, the applicant has developed a sash in which the shoji is moved from the running position when the window is opened to the ventilation position, and then moved in parallel from there to the position when the window is closed and locked to close the window flush. Patent Application No. 57-49053 (Japanese Patent Application No.
58-168779), Utility Application No. 58-52031 (Sho 59-
No. 158670).

[Problems to be solved by the invention] Conventionally, such shoji screens have been designed to be locked by attaching a tightening handle to each one, so the number of tightening handles is large, which not only makes operation complicated, but also makes the appearance unsightly. I don't do it.

[Means for Solving the Problems] The present invention improves the problems of the conventional method, and is a sliding window in which the shoji are lined up flush when the window is closed, and after moving to the indoor side, they slide in the left and right direction. A tightening rod is provided near the upper and lower ends of the connecting frame of the movable shoji in parallel to the connecting frame, and a pair of connecting rods that are perpendicular to each side of the tightening rod and whose sliding directions are opposite in the horizontal direction are attached to the tightening handle. The rear end of the tightening rod is connected to a slider that slides in conjunction with the locking and unlocking operations of the tightening handle attached to the stile, and the tip of the tightening rod is Arranged so as to fit into the fitting hole of the clamping receiver provided in the frame, and
This sash locking device is characterized in that one of the pair of connecting rods is in a position where it can push out the slider of an adjacent shoji with its tip.
As an example of its implementation, a concave groove is provided at the tip of one of the connecting rods in the above device, and an engagement arm with the connecting rod is pivotally attached to the slider at the corresponding position.
An operation transmission mechanism is provided in which a detachment guide rod that urges a predetermined rotation of an engagement arm is fixed to a predetermined position of a shoji screen, and a slider is loosely inserted into a sliding path of a side wall.

[Example] Examples will be described below with reference to the drawings.

FIG. 1 is an interior view of a sliding window in which shoji 1 and 2 are lined up flush according to the present invention. A locking handle 4 is provided on the connecting frame 3 of one of the shoji 2, and locking and unlocking are performed by rotating the locking handle 4. Also, to open the window, grasp the handle 4 and pull the shoji 2 toward the inside of the window as shown in Figure 2, and then open and close the shoji 1 and 2 by sliding them as shown in Figure 3. .

FIG. 4 shows the locking structure applied to the sliding window, FIG. 5 is a top view thereof, and FIG. 6 is an enlarged perspective view of the locking device.

In FIG. 4, the locking device 5 is attached near the upper and lower ends of the stile 3 of the shoji 2 that moves parallel to the indoor side and then moves left and right.

Its shape will be explained with reference to the enlarged detailed view of FIG.

A locking rod 6 that is parallel to the connecting frame 3 and can freely slide vertically, and a pair of connecting rods 7 and 8 that are perpendicular to this and whose sliding directions are opposite in the horizontal direction are connected to a dogleg-shaped link 9,
10, each is attached to the shaft. Connecting rod 7,
8 is held between a mounting board 11 and guide groove plates 12 and 13. Mounting board 1 through which the tightening rod 6 penetrates
A hole 14 is opened at position 1. Further, the mounting board 11 is provided with screw holes 15 at appropriate locations for mounting the locking device on the shoji 2. A slider 16 is pivoted to the lower end of the tightening rod 6, which converts the rotation of the tightening handle 4 for locking and unlocking into linear motion and transmits this motion. A slider 19 is pivotally attached to the tip of the connecting rod 8 for transmitting linear motion to tightening rods 18 built into the upper and lower ends of the rigid rod 17.

Tighten rods 21 at the upper and lower ends of the rigid frame 20 of the shoji 1.
It has a built-in and is connected to slider 2.

At the corresponding frame position of each tightening rod 6, 18, 21, a tightening receiver 24 having a fitting hole 23 into which the tip of the tightening rod enters and is clamped is attached. That is, the positions are the upper and lower frame positions of the door frame 3 and the upper and lower left and right jambs.

In this configuration, when the tightening handle 4 is rotated 180 degrees in the locking direction, the slider 16 moves linearly in the direction of the arrow shown in FIG. 4 due to the rack and pinion type movement conversion mechanism. Then, the tightening rod 6 of the locking device 5 passes through the hole 14 of the mounting board 11 and enters and engages with the fitting hole 23 of the tightening receiver 24 of the frame. That is, the top and bottom of the stile 3 of the shoji 2 are firmly connected to the frame.

Linear movement of tightening rod 6, dog-shaped link 9,
10 to change the direction and move the connecting rods 7, 8 in the horizontal direction. The connecting rod 8 connects the tightening rod 18 via the slider 19 to the tightening receiver 2 of the frame.
4 into the fitting hole 23. On the other hand, the connecting rod 7 passes through the notch hole of the corresponding shoji 1 to the slider 22.
Press to create a linear motion as shown by the arrow in Figure 4.
The tightening rod 21 is inserted into the fitting hole 23 of the tightening receiver 24 of the rigid frame.
to rush into.

Note that when the tightening handle 4 is rotated 180 degrees in the unlocking direction, the reverse operation described above occurs, and each tightening rod 6,
18, 21 are disengaged from the tension receiver 24, and the shoji 1, 2 can be moved.

Here, in order to separate the tightening rod 21 of the shoji 1 from the tightening receiver 24, it is necessary to move the slider 22 linearly in the direction opposite to the arrow shown in FIG. Therefore, a spring body may be attached to the slider 22 to cause it to retreat, or the retreating movement of the connecting rod 7 of the tightening rod 6 may be transmitted to the slider 22.

This structure is shown in perspective view in FIG. That is, a concave groove 26 in which the engagement arm 25 can be engaged is provided at the tip of the connecting rod 7, and when the lock is locked, the engagement arm 25 is rotated by being guided by the side wall 27 of the sliding path, as shown in FIG. By making it into an engaged state, when the connecting rod 7 is moved back by an unlocking operation, the slider 22 is also pulled and moved back. Therefore, the connection between the tightening rod 21 and the tightening receiver 24 is released. When the connecting rod 7 retreats by a predetermined amount, the engagement arm 25 collides with the detachment guide rod 28, as shown in FIG. Then, guided by this, the engagement arm 2
5 rotates and separates from the groove 24, and the connection between the slider 20 and the connecting rod 7 is broken.

The connecting rod 7 is further retreated to a predetermined unlocking position. In this way, the engagement arm 25 is pivotally attached to the slider 22 at the position corresponding to the upper and lower tightening rods 6 of the joining frame of the shoji 1, and an operation transmission mechanism is provided in which the detachment guide rod 28 is attached to the shoji 1. The sliding window can be unlocked by one rotation of the handle 4.

[Effects of the invention] This invention requires only one rotation of the tightening handle.
Locked at the top and bottom and left and right jambs of the stile,
In addition, since it is unlocked, it is easy to operate, and 1.
Since only one tightening handle is required, the window has a clean appearance. Furthermore, since each part of the shoji is locked, the wind pressure load can be dispersed and supported.
The rigidity of each member of the shoji can be reduced, making it economical, and in addition, each shoji can be firmly connected to the frame without rattling, resulting in a sash with excellent airtight and watertight performance.
