At this time, a click feeling is generated at the start end and the end of the operation of the operation lever 18 by the action of the click spring 26 as a torsion coil spring elastically mounted in the case 9.

On the other hand, as shown in FIG. 2, an elongated plate-like trigger 27 is rotatably supported at the center thereof by a guide pin 14 below the case 9, and one end of the trigger 27 (the upper end in FIG. 2). ) Is urged outward (to the right) by the elastic force of a trigger spring 28 as a torsion coil spring elastically mounted below the case 9.

As shown in FIG. 2, a locking projection 29 is formed at the lower end of the first hook.
Numeral 9 faces the other end (lower end) of the trigger 27 when the window shown in FIG.

As shown in FIG. 2, an upper pulling mechanism 6 is provided near the upper locking roller 2 in correspondence with the lower pulling mechanism 7 having the above-described structure.

The upper pulling mechanism 6 is composed of the second kama 32 itself forming the pulling blade 15 having the same configuration as the above-mentioned pulling blade. The second kama 32 and the first kama 13 are integrally formed by a connecting rod 31. Are combined.

As shown in FIG. 1, the connecting rod 31 is fitted into an unnumbered guide groove formed on the inner surface 5 of the window frame, and is guided so as to be vertically movable.

The position of the locking edge 16 in the upper and lower pulling mechanisms 6 and 7 is determined by the position of the locking roller of the sliding door 1 in the closed position when the pulling blade 15 is raised as shown by a chain line in FIG. 2 is set.

When the window is open, that is, when the sliding door is separated from the window frame, the locking rollers 2, 2 in FIG. It is far to the right.

At this time, one end (upper end) of the trigger 27 is urged outward by the resilience of the trigger spring 28 and is at the angular position shown by the solid line. Therefore, when the knob 22 is pushed down to activate the lock device, The locking projection 29 of the first brace 13 abuts on the other end of the trigger 27.

Therefore, the operating lever 18 cannot be further depressed, and the upper and lower pulling mechanisms 6, 7
Since the pulling blades 15 and 15 do not rise, it is possible to prevent the locking roller 2 from colliding with the pulling blade 15 when the window is closed.

When the window is closed, as shown in FIG. 2, the locking rollers 2, 2 provided on the free side edge of the shoji move over the upper end of the pulling blade 15 and move to the vicinity of the closed position shown by the chain line. .

Normally, a packing material (not shown) is inserted between the sash and the window frame to maintain airtightness, so that the locking roller 2 is located slightly to the right of the position shown by the chain line in FIG. .

At this time, one end of the trigger 27 is pushed by the lower engaging roller 2 and moves inward (not shown), and the other end of the trigger moves outward to engage the first hook. The locking device deviates from the movement trajectory of the stop projection 29, so that the locking device can be operated.

In this state, when the operation lever 18 is rotated counterclockwise in FIG. 2 by operating the knob 22 from the indoor side, the connection is established via the first stick 13 and the connection rod 31 as described above. The second comb 32 rises integrally.

Then, the inclined edge 17 of each pulling blade 15 first comes into contact with the corresponding locking roller 2, and the locking roller 1 and the locking roller 1 against the elasticity of the packing material by the wedge action generated therebetween. The integral shoji 1 is drawn to the window frame. Thereafter, the engaging edge 16 of the pulling blade rises while slidingly contacting the engaging roller 2 or rotating the engaging roller, and then ascends to a position shown by a chain line in FIG. 2 and stops.

In this locked state, the reaction force which the locking edge 17 receives from the locking roller 2 acts vertically on the locking edge.
Since there is no component force to pull the blade downward in response to an external force that attempts to open the sash, the sash can be stably locked to the window frame.

When the window is opened, the knob 22 at the end may be returned to the original position. In this case, as shown by a solid line in FIG. You can open the shoji.

[0044]

As is apparent from the above description, the present invention combines a pulling blade having an inclined edge and a locking edge connected to a kama, and firstly attaches to the locking roller of the shoji at the inclined edge. Because of the engagement, the sash can be drawn to the window frame by the wedge action generated between them.

Further, since the shoji is pressed against the packing material of the window frame and locked by the pulling function, the shoji is sandwiched between the packing material and the locking edge so that it does not rattle.

Further, a trigger controlled by the locking roller at the time of closing the window is provided so that the camera does not move unless the window is closed, so that the collision between the drawing blade and the locking roller at the time of closing the window is prevented. be able to.

In addition, the length of the locking edge and the amount of movement of the stirrer can be freely set, so that the relative position of the locking roller with respect to the window frame changes greatly depending on the degree of opening of the sliding door, such as a vertical sliding window. When the present invention is applied to a window, by increasing the amount of movement of the stoma, the locking roller can be securely pulled into engagement with the blade and locked without completely closing the window. To play.
