Description

[Detailed explanation of the invention] Purpose of the invention (industrial application field) This invention is a system in which a fixed shoji and a movable shoji are closed on the frame body in a state where they are lined up on the same plane, and the movable shoji is jumped parallel to the fixed shoji. This sash is of the type that is opened by sliding it in the direction in which it overlaps with a fixed sash, and it relates to a device that maintains a movable sash adapted to this sash in a protruding state.

(Prior Art) This type of sash is disclosed, for example, in Japanese Patent Application Laid-Open No. 57-209377, and its configuration is such that a door roller running on a rail and a movable shoji are connected via a link. When the movable shoji is to be jumped out, by turning the handle provided on the movable shoji, the link is rotated around the pivot point with the door roller by the actuating rod that reciprocates in a straight line in conjunction with the handle. The movable shoji is moved in parallel, and after jumping out, the movable shoji is slid open along the rail.

(Problems to be Solved by the Invention) By the way, in the configuration according to the above-mentioned publication, if the handle is erroneously rotated to return to its original state while the movable shoji is being slid open after it has been raised,
The operating rod moves back and the links rotate, so while the movable shoji slides open and close, it begins to move so that it closes on the same plane as the fixed shoji, and collides with the fixed shoji, so after the movable shoji has jumped out, the operating rod It was necessary to keep the movement of the robot fixed, and there was a problem with the locking method.

This invention is an attempt to solve the above-mentioned problems, and provides a movable shoji protrusion holding device for a movable sliding sash that has a simple structure and is capable of reliably locking and maintaining the movable shoji in its protruding state. There is a particular thing.

Structure of the invention (means for solving problems) The movable sliding sash holding device for the movable sliding sash according to this invention has a lock lever that swings up and down on the movable sash at its intermediate part, and A block is provided with a hook at its tip that elastically engages with the locking part of the operating rod in the movable shoji, and the vertical frame of the frame has an inclined surface to release the hook of the lock lever from the locking part. A piece is provided between the closed position and the pop-up position of the movable shoji.

(Operation) Until the movable shoji jumps from the closed state on the same plane as the fixed shoji, the operating rod is unlocked and the handle can be rotated, but when the movable shoji jumps out and slides slightly open. At the same time, the lock lever is disengaged from the block piece, and the hook portion engages with the locking portion of the operating rod, thereby stopping the movement of the operating rod.

(Example) As shown in FIGS. 4 and 5, the pop-out sliding sash according to the present invention has a fixed shoji 2 on the right side inside the frame 1.
The movable shoji 3 are arranged on the same plane on the left side, and by turning the handle 4 provided on the shoji, the movable shoji 3 is moved in parallel toward the indoor side to a position where it does not interfere with the fixed shoji 2 and jumps out. After that, it has a function of sliding open along the rail 5 on the indoor side in the direction overlapping with the fixed shoji 2. Furthermore, the fixed shoji 2 is not simply fitted, but is usually fixed to the frame 1 with locks 6, but by removing the locks 6, it can be slid along the outdoor rail 7. Furthermore, the means for jumping out the movable shoji 3 is shown in FIG. 6, which connects the door roller 8 running on the indoor rail 5 and the lower surface of the movable shoji 3 with a link 9, and has two notches at the tip of the link 9. Notch recess 10,1
1 is provided, and on the other hand, an operating rod 12 is provided in the lower stile of the movable shoji 3, and the operating rod 12 moves linearly and reciprocally according to the rotation of the handle 4.
A pair of rolls 13 and 14 that fit into the operating rod 12
are provided one after the other in the direction of movement of the operating rod 1.
2 moves forward in the direction of the arrow 15, the preceding roll 13 fits into the recess 10 and the link 9
to try to rotate the door roller 8 toward the outdoor side with respect to the movable shoji 3 by pushing, but since the movement of the door roller 8 on the outdoor side is blocked by the indoor side rail 5, the reaction force causes the door roller 8 of the link 9 to rotate. The pivot point moves toward the indoor side, and the movable shoji 3 is pushed out toward the indoor side as shown by the two-dot chain line. When the operating rod 12 is moved back, the movable shoji 3 is moved back to its original position.

Next, the movable shoji projecting holding device according to this invention will be explained. As shown in FIGS. 1 to 3, a lock lever 17 is attached to a block 16 fixed to the corner of the lower frame of the movable shoji 3 at an intermediate portion thereof. is pivoted so as to swing up and down, and the lock lever 17 is configured such that a spring 18 urges the tip of the movable shoji 3 toward the center upward. On the other hand, a block piece 19 having an inclined surface that becomes lower in the direction in which the movable shoji 3 slides open is fixed to the vertical frame of the frame 1 between the closed position and the protruded position of the movable shoji 3. There is. Further, a hook portion 20 bent upward is provided at the tip of the lock lever 17 near the center of the shoji 3, and a hook portion 20 is provided on the operating rod 12 opposite thereto, so that when the rod 12 moves forward and the movable shoji 3 springs out, the hook portion 20 is bent upward. A locking portion 21 consisting of a hole facing the portion 20 is provided, and when the lock lever 17 is disengaged from the block piece 19, the hook portion 20 is fitted into the locking portion 21 by the elastic force of the spring 18, and is activated. This prevents the rod 12 from moving. The action of releasing this blocking state is performed by the block piece 19, and the block piece 19 of the lock lever 17
An inclined surface 22 which is placed on the block piece 19 and is similar to the slope of the block piece 19 is provided at the end facing the block piece 19, and when this inclined surface 22 is placed on the block piece 19, the hook part 20 can be Lowering locking part 21
It's becoming easier to escape.

(Effect of the invention) The movable shoji pop-out holding device of the pop-out sliding sash according to this invention has a lock lever equipped with an inclined surface and a hook portion pivoted to the movable shoji so as to be able to swing up and down, and the lock lever is attached to the frame body. A block piece is provided to release the lock, and when the movable shoji pops out, the lock is still open, and when the movable shoji slides open slightly, the lock lever comes off the block piece, and the lock lever is released by the elastic force. The hook portion rises and engages with the locking portion of the opposing operating rod to lock the door.During the sliding opening/closing of the movable shoji, the movement of the operating rod is fixed by the lock lever, and the movable shoji This also prevents the movable shoji from moving back toward the same plane as the fixed shoji, thus ensuring that the movable shoji can move along the rail without contacting the fixed shoji. It slides open and close. In addition, the lock lever is released by the contact between the block piece with the inclined surface and the end of the lock lever which is pivoted at the middle part, so when the movable shoji is slid to close, the sliding movement causes the end of the lock lever to be released. The locking state is released when the sliding door is placed on the block piece, and the movable shoji can be moved back without any trouble.
