2. Description of the Related Art This type of telescopic partition is used for, for example, a surface grid, a gate, and the like.
A simultaneous expansion and contraction mechanism is provided which is capable of simultaneously expanding and contracting by arranging a link between the plurality of crosses via a fixed shaft which is rotatable on the cross and a movable shaft which is slidable in the longitudinal direction of the cross. In order to maintain the extended state (closed state) of the telescopic partition, the end bar is fixed between the end bar (for example, a door stop bar) and a fixing frame (for example, a column) that receives the end bar. For example, a lock device that can be released, such as a sickle lock or a locking device using a pin and a hook, is installed.

Secondly, the locking device has a simple structure so that the operation is reliable and easy to use. Fourth, it is an object of the present invention to provide a preferred form of a surface grid formed by an elastic partitioning body. The fourth object of the present invention is to make the surface grid excellent in security and capable of performing an emergency operation easily and reliably.

The turning radius toward the longitudinal direction is set so as to intersect the glass panel surface of the window sash B.

In this embodiment, the lock device 11 locks the single movable shaft 6 by setting the lock device 11 to one of the simultaneous telescopic link mechanisms 3 of the upper and lower two-stage simultaneous telescopic link mechanism 3. The lock device 11 includes a fixed base 12 fixed to the bar 2 and a protruding portion of the fixed base 12 protruding toward one side in the longitudinal direction of the bar 2 to move the movable shaft 6. And the above X linked by this
A lever holder 13 having a U-shaped cross section having a length exceeding the dimension of the rotatable connecting portion of the U-shaped link 4 and a lever holder 13 having a rear opening and a tip end position of the lever holder 13 in the protruding direction is rotatable. By supporting the end portion at the end and having a length longer than the interval between the telescopic partition 1 and the window sash B,
A lever handle 14 whose turning radius intersects with the glass surface of the window sash B;
Reference numeral 4 denotes an L-shaped side surface orthogonal to the lever handle 14 so as to protrude rearward at one end in the longitudinal direction of the shaft support side end through the through hole or the long hole 16 of the lever holder 13. It is made of metal with a stopper 15,
As a result, the lever handle 1 is attached to the lever holder 13.
4, the lever handle 14 is made parallel to the bar 2 and the stopper 15 is flipped up to open the path of the movable shaft 6 and make the movable shaft 6 slidable. On the other hand, the lever handle 14 is pulled out from the lever holder 13, and the lever handle 14 is turned by 180 ° so as to be parallel to the beam 2 so that the lever handle 14 is in series with the lever holder 13. By projecting from the lever holder 13 to the back side thereof, the stopper 15 is protruded into the path of the movable shaft 6 to prevent its sliding and lock the movable shaft 6.

At this time, in the present embodiment, the lever handle 14

Therefore, in the case of the surface grating A of this embodiment, the lever handle 1 of the lock device 11 is set when or after the surface grating is installed.
4 is suspended, the stopper 15 protrudes into the path of the locking movable shaft 6 to prevent the movable shaft 6 from sliding, thereby locking the movable shaft 6 so that it cannot slide, and the locking device 11 is installed. At the crossbar 2, the simultaneous telescopic link mechanism 3 is restrained in the extended state to prevent the telescopic movement, especially the opening of the telescopic partitioning body 1 due to the contraction.
The window sash B hinders the rotation of the window sash and causes a release obstacle, so that the lock device 11 cannot be released and the security of the screen grid A is secured. In an emergency, the window sash B is opened by removing the crescent from the indoor side. By doing so, the obstacle for releasing the lock device 11 is eliminated, and the stopper 15 is movable by operating the lock device 11 by rotating the lever handle 14 to the lever holder 13 side by 180 ° while lifting the lever handle 14 from the indoor side. The movable shaft 6 is slidable by releasing from the path of the shaft 6 and opening the path, thereby releasing the constraint of the simultaneous telescopic link mechanism 3 so that it can be contracted and fixed. The telescopic partitioning body 1 can be folded and opened toward the one end end side fixed by 10 to allow escape from the room to the outside, and also, for example, from the outdoor side By breaking the glass panel of the sash B, also operates the locking device 11, to permit entry rescue from the outdoor side of the firefighter or the like, can be any suitable surface lattice for emergency escape.

The bar is provided with a single telescopic link mechanism that can be extended and contracted independently, such as by a single bar link that is rotatably fixed via fixed shafts at both ends. The movable shaft of the link mechanism is locked so as not to slide, and the relationship between the crosspiece and the telescopic mechanism is arranged such that the front and rear crosspieces sandwich the telescopic mechanism. When using, the stopper should be made to protrude into the path of the movable shaft through a through hole provided in the back side bar. When the simultaneous telescopic link mechanism is an X-shaped link as described above, In a stretched state, for example, a curved X-shaped link or a wave-shaped X-shaped link for improving the appearance of the expandable partitioning body, for example, by forming a circular shape, etc. By using an L-shaped slider slidably installed in the longitudinal direction, a stopper at the tip of the slider is supported to support the movable shaft, so that the movable shaft is locked so as not to slide. A slider lock at a fixed position is provided to prevent and prevent the stopper from coming into contact with the movable shaft. The lever hand is configured to be released, for example, to be used for a telescoping partition which is required to open and close both inside and outside such as a gate. When using an operation lock device, it shall also be provided with a handle lock. Similarly, the operation shall be performed by two operations of the operation of the handle lock and the rotation of the lever handle. Use a rectangular frame, U-shaped frame, etc. with a guide rail frame for fixing the building frame. When using the above-mentioned square frame, expand and contract inside the frame. By mounting the partitioning body and surrounding it with a frame, the mounting of the telescopic partitioning body can be performed in a non-fixed, bidirectionally expandable and contractable manner. The horizontal rail of the present invention can be expanded and contracted by a telescopic mechanism. Instead of the above-mentioned one for expanding and contracting in the left and right directions, it is the same one for expanding and contracting in the vertical direction. Lever handle operation In order to unlock the movable shaft by pulling the lever handle out of the lever holder and rotating it, the lever is received and fitted to hold the lever handle. Used to lock the movable shaft of the lower-side simultaneous telescopic link mechanism of the two upper and lower stages.
