1a may be made to face the connecting rod 180b and engage with the ball 180a. In this case, in order to prevent the ball chain 180 from deflecting, a substantially semicircular guide 182 may be formed extending in the longitudinal direction.

42 and 43a and 43b show a ninth embodiment of the slider lock, in which the guide piece 184 of the slide plate 183 is slidably fitted into the guide groove 182 of the slider 61, and the slide plate 183 is made vertically movable until it hits the vertical stoppers 185 and 186 attached to the top and bottom of the slider 61, and a rod-shaped locking body 188 is loosely fitted into the hole 187 of the slide plate 183, and its tip is It fits tightly into the hole 189 of the slider 61 and is biased by the spring 190 in the direction of fitting into the engagement recess 191, so that the base conical surface 188a of the locking body 188 is inserted into the funnel-shaped hole 187 of the slide plate 183. The handle 70 is attached to a long groove 192 formed on both sides of the slide plate 183 so as to be in close contact with the surface 187a, and to be slidable up and down.

In this way, as shown in FIG. 43a, the locking body 188 is urged by the spring 190 in the direction of fitting into the engagement recess 191, and the base conical surface 188a is brought into close contact with the funnel-shaped surface 187a. While pressing and holding the slide plate 183 against the slider 61, the locking body 18
8 fits into the engagement recess 191 and the slider 61
can be held so that it does not move up and down.

Furthermore, when the handle 70 is held and pulled downward, the slide plate 183 moves downward as shown in FIG.
Since the locking body 188 is pulled and moved against the spring 190 by the wedge action between the base conical surface 188a and the locking body 188, the locking body 188 comes out of the engagement recess 191, so that the slider 61 can be moved downward. When the handle 70 is pulled upward, the locking body 188 is separated from the engagement recess 191 in the same manner as described above, so that the slider 61 can be moved upward by the handle 70.

Note that the hole 187 of the slide plate 183 may be formed with a slope that slopes upward and downward, and the locking body 188 may be formed with a similar slope. It can also be made to be stretched.

44 to 47 show a tenth embodiment of the slider lock, in which a corrugated locking recess 200 is provided, and the slider 61 has a pair of mounting blocks 201,
201 and its pair of mounting blocks 201, 201
A recess 202 is formed in between, and the base of the locking body 203 is fixed below the bottom of the recess 202 with a pin 204 so that the arcuate tip 205 protrudes from the hole 206 of the slider 61 into the locking recess 200. It is attached so as to be swingable, and the arc-shaped tip 205 is engaged with the locking recess 200 by swinging and biasing in the protrusion direction by the leaf spring 207.

As shown in FIG. 47, the plate spring 207 has a tongue piece 207b formed by punching out a part of a base plate 207a.The base plate 207a is provided in the recess 202 of the slider 61 and the locking body 203 A cam 209 is pressed against the tongue piece 207b, and the tongue piece 207b is left free, and the cam 209 supported by the shaft 208 between the pair of mounting blocks 201 is brought into contact with the tongue piece 207b.
8 is connected to a handle 70.

Because of this, when the handle 70 is set vertically and the tongue piece 207b is strongly pressed with the cam 209, the leaf spring 20
7 becomes large and the arc-shaped tip 205 of the locking body 203 strongly engages with the locking recess 200, so that
The holding force of the slider 61 becomes stronger, and the slider 61 can be held so that it does not move due to the blind's own weight, and when the handle 70 is rotated, the cam 209 moves against the tongue piece 2.
07b and the pushing force becomes weaker, the spring force of the leaf spring 227 becomes weaker, and the force with which the arcuate tip 205 of the locking body 203 engages with the locking recess 200 becomes weaker. As the holding force of the slider 61 becomes weaker, the slider 61 moves upward by the weight of the blind, and also moves downward by pulling down the handle 70 with a light force. At this time, the locking recess 2
00 has a wave shape, and since the arc-shaped tip 205 of the locking body 203 is engaged, the locking body 203 moves over the locking recess 200 smoothly.

Effects of the invention: The blind can be opened and closed by moving the slider by operating the handle that protrudes from the groove.
In addition to simplifying the operation of opening and closing the blinds, the grooves along which the window stile or frame slider runs can be made smaller, so the stile or frame does not become particularly large, which has a large cost effect and improves the window performance. It has excellent practical effects that can improve the design of the product.
