Further, it is possible to provide a vertical blind slat suspending device that allows a plate-like slat to be easily attached to and detached from a hook of a runner.

  Hereinafter, an embodiment embodying the present invention will be described with reference to the drawings. In the vertical blind shown in FIG. 1, a large number of runners 2 are supported so as to be movable in a hanger rail 1, and slats 4 are suspended and supported on a suspension shaft 3 of the runner 2. Then, when the runner 2 moves in the hanger rail 1 by the operation of the operating device, the slat 4 is transferred along the hanger rail 1, and each slat 4 rotates in the same phase as the suspension shaft 3 rotates. Is done.

The slat 4 is formed of a wooden plate material, and is suspended and supported by a hook 2 a provided at the lower end portion of the suspension shaft 3. The configuration of the suspension device will be described below.
As shown in FIG. 2, a rectangular cutout 5 is formed at the center in the width direction at the upper end of the slat 4, and a mounting hole 6 is formed below the cutout 5.

  A hanger plate 7 formed by bending a metal plate is attached to the cut portion 5. That is, a through hole 8 is formed in the lower part of the hanger plate 7, and a nut member 9 is fitted into the mounting hole 6 from one side surface of the slat 4. The hanger plate 7 is fixed to the slat 4 by screwing screws 10 inserted into the through holes 8 of the hanger plate 7 from the other side of the slat 4 into the nut member 9.

  As shown in FIGS. 3 and 4, both sides of the upper end portion of the hanger plate 7 are bent in the horizontal direction, and the tip end portion thereof is bent into a cylindrical shape to form a pair of bearing portions 11 a and 11 b. . A groove portion 12 is formed inside each of the bearing portions 11a and 11b, and an oblique side (first rotation restricting portion) 13 directed upward is formed on a side edge of the bearing portions 11a and 11b constituting the groove portion 12. Is formed.

  Further, at the inner ends of the bearing portions 11a and 11b, on the opposite side of the hypotenuse 13 with respect to the centers of the bearing portions 11a and 11b, there are projecting portions (second rotation restricting portions) 14 protruding in an arc shape. Is formed.

  A latch 15 formed by bending a metal wire having a circular cross section is supported on the bearing portions 11a and 11b. The latch 15 is bent in a crank shape, and both end portions thereof are inserted into the bearing portions 11a and 11b. Therefore, the latching tool 15 is supported so as to be rotatable between the bearing portions 11a and 11b.

  As shown in FIG. 4, the latching tool 15 is held in an oblique direction in a state in which the vicinity of both ends abuts against the hypotenuse 13 due to its own weight. Further, when the latching tool 15 is rotated in the direction of the arrow A from the state shown in FIG. 4, the vicinity of both ends of the latching tool 15 abuts on the protrusion 14, so that the vertical direction is almost the range. It can be rotated.

In the state where the latching tool 15 is rotated in the vertical direction, the height of the upper end portion of the latching tool 15 is formed to be substantially equal to the upper edge of the slat 4.
When a strong rotational force in the direction of arrow A is applied to the latch 15 from the state in which the latch 15 is pivoted to the vertical direction, the latch 15 can move over the protrusion 14 and rotate. .

Next, an operation for suspending and supporting the slat 4 provided with the suspending device as described above on the hook 2a of the runner 2 will be described.
When attaching the slat 4 to the runner 2, as shown in FIG. 5, it lifts so that the upper end part of the slat 4 may approach the hook 2a. At this time, the latching tool 15 is held in a state of extending obliquely upward from the bearing portions 11a and 11b.

  Then, as shown in FIG. 6, when the hook 2a is positioned in the latch 15 and the slat 4 is lowered while sliding in the direction of the arrow B in FIG. As shown in FIG. 7, the slat 4 is hooked on the hook 2a and supported by the hook 2a.

  On the other hand, when removing the slat 4 from the hook 2a, if the slat 4 is lifted upward from the state shown in FIG. 7, the latching tool 15 is rotated obliquely by its own weight as shown in FIG. At this time, the latch 15 is not rotated to the opposite side by the action of the protrusion 14 of the hanger plate 7.

In this state, when the slat 4 is lowered so that the hook 2a is pulled out from the hook 15, the slat 4 is detached from the hook 2a as shown in FIG.
Further, when the slat 4 is lifted from the state shown in FIG. 7, even if a large force in the direction of arrow C acts on the latch 15 by mistake, the latch 15 can move over the protrusion 14 and rotate. Damage to the hook 15 or the hook 2a is prevented.

In the vertical blind slat suspending device configured as described above, the following operational effects can be obtained.
(1) The slat 4 is supported in a suspended manner from the hook 2a via a hook 15 and the hook 15 is formed of a wire having a circular cross section. Therefore, even when the slat 4 swings along its traveling direction, the hook 15 can be easily rotated in the hook 2a. Therefore, even when the slat 4 swings, the hook 2a or the latch 15 is not damaged.
(2) To attach the slat 4 to the hook 2a, the slat 4 is lifted upward, the hook 2a is inserted into the hook 15 and the slat 4 is lowered in this state to hook the hook 15 on the hook 2a. Just do it. Further, when removing the slat 4 from the hook 2a, the slat 4 may be lowered after lifting the slat 4 upward and removing the latch 15 from the hook 2a. Therefore, the attaching / detaching operation of the slat 4 with respect to the runner 2 can be easily performed.
(3) When the slat 4 is attached to or detached from the runner 2, it is not necessary to tilt the slat 4 in an oblique direction. Therefore, even if the slat 4 is plate-shaped, the slat 4 can be easily attached and detached without interfering with adjacent slats and window surfaces.
(4) Due to the protrusions 14 provided on the hanger plate 7, the latch 15 is inclined in only one direction when the slat 4 is attached or detached. Therefore, the attaching / detaching operation of the slat 4 can be performed smoothly.
(5) The protrusion 14 has an arcuate shape that allows the hook 15 to get over when a rotational force of a predetermined value or more acts. Therefore, even if an unnecessary rotational force acts on the latch 15, damage to the latch 15 or the hook 2 a can be prevented.
(6) The hanger plate 7 is attached to the cut portion 5 at the upper end of the slat 4, and the height of the upper end of the latch 15 attached to the hanger plate 7 is substantially coincident with the upper edge of the slat 4. did. Therefore, the gap between the upper edge of the slat 4 and the hanger rail 1 can be reduced, and light leakage from this gap can be reduced.
