Description

[Detailed description of the invention] This invention is a blade opening/closing device for vertical blinds that allows the blades of the blind to be opened and closed smoothly and to reduce the burden on the stored runner case. This relates to a spacing plate.

In this type of device that has been commonly used in the past, a runner case with a spacing plate between the rotating body and the blades is disposed inside the picture frame attached to the top of the blind vane, and the space inside the picture frame is The opening/closing angle of the hanging blind blades is adjusted by the rotation of the rotating body through the pole chain, the guide shaft, and the screw shaft, and the opening/closing action of the blind blades is performed by sliding the spacing plate. It is.

As shown in Fig. 1, the conventional spacing plate has one end bent upward to form a locking tongue a to the runner case, and the other end bent downward to form a locking tongue piece a. When assembled, a locking protrusion C is formed and serves as a retaining part to the runner case.
This engaging part is fixed to the insertion hole of the runner case, and the locking tongue piece a of another spacing plate whose one end is fixed to the runner case is inserted into the insertion hole of this fixing part. are placed within the image frame as appropriate.

When the blind vanes are opened, the spacing retaining plate runs and its locking tongue a is locked to the fixed part of the adjacent runner case to maintain the spacing between the blind vanes. When closing the blade, the runner case is pulled and the spacing plate runs in the opposite direction to open and close the vane.

However, in the conventional spacing plate as described above, the locking portion to the runner case is formed as a locking tongue piece a with one end bent. Since this locking piece a becomes a hindrance, it is necessary to insert the spacer plate with one end not bent into the runner case, and then bend one end to form the locking tongue piece a.

Therefore, the work of attaching the spacer to the runner case becomes extremely troublesome, and the work of molding the spacing plate is also time-consuming and inefficient.

In addition, when the blind vanes are closed, the locking tongues a of the many spacing plates overlap, but since the locking tongues a are thick, the overlapping portion becomes thick and interferes with its function. In addition, the weight of this part places a heavy burden on the leading runner case, resulting in problems with its durability.

Therefore, in order to eliminate the above-mentioned drawbacks, this invention has a hole for inserting the spacing plate into the runner case, and an engaging pawl and a locking protrusion that engage with the runner case at one end of the spacing plate. and a guide for closing the blind vanes is provided near the guide so that one end of the runner case and the spacing plate are engaged, and a guide for opening the blind vanes is provided at the other end of the spacing plate. By providing a guide and forming protrusions for locking onto other runner cases near the guide, the work of attaching the spacing plate to the runner case is made simple and easy, and the opening/closing action of the blind vanes is made smooth. This invention was developed for the purpose of providing a spacing plate for a vertical blind blade opening/closing device that allows the blades to be opened and closed.

Now, one embodiment of the spacing plate in the vertical blind blade opening/closing device according to this invention will be described in detail with reference to the drawings. Reference numeral 1 denotes a spacing plate, one end of which is curved to open the blind blade 2. A guide 3 is formed, and a protrusion 5 for engaging the runner case 4 is formed upward near the guide 3, and the other end is bent to provide a protrusion 5 for engaging the runner case 4. A pair of claws 6 and a locking protrusion 5' are formed downward, and a guide 7 for opening and closing the blind vane 2 is formed in a chevron shape near these.

The reason why the locking protrusions 5 and 5' project in opposite directions is to ensure smooth movement of the spacing plate 1, especially when the blind tool plate 2 is closed.

On the other hand, the runner case 4 is provided with an insertion hole 17 through which the spacing plate 1 is inserted, and is configured to engage with one end of the spacing plate 1. 9 and a second rotating body 11 having vertical grooves 10 that mesh with the horizontal grooves 8 of the first rotating body 9.

Then, within the box frame 12, the pole chain 14 is inserted through a sprocket or the like into a hole 13 made in the center of the first rotating body 9.
By inserting the guide shaft 15 meshed with the guide shaft 15 and rotating it, the opening/closing angle of the blind vane 2 suspended via the hook 16 is adjusted.

Thus, the spacing plate 1 is inserted into the insertion hole 17 provided in the runner case 4, the engaging claw 6 is engaged with the outer wall of the runner case 4, the locking protrusion 5' is engaged with the inner wall of the runner case 4, and the runner Fix it to case 4.

At this time, since one end of the spacing plate 1 is not formed as a bent locking tongue piece as in the conventional case, the locking protrusion 5 and opening guide 3 are formed and then attached to the runner case 4. It can be inserted into the insertion hole 17 of , and the installation work is extremely simple and easy.

Thus, a desired number of spacing holding plates 1 are attached to each runner case 4, and a lid 18 is fitted thereon, and a screw shaft 20 is inserted into a guide hole 19 formed in the runner case 4.
The other pole chain 14 is inserted through the pole chain 14 and connected to the screw shaft 20.
By rotating the screw shaft 20, the blind vane 2 is moved laterally.

In this case, when opening the blind vanes 2, the spacing plate 1 runs and its locking protrusion 5 is locked to the adjacent runner case 4 to maintain the interval between the blind vanes 2, that is, the interval. Only the length of the holding plate 1 is kept constant, and at this time, the traveling guide 3 is held by the lid body 18 due to its curved portion.
It slides into contact with the inner wall of the door and runs smoothly when it is opened.

Furthermore, when closing the blind vanes 2, the spacing plate 1 runs in the opposite direction, but the chevron-shaped closing guide 7 guides the other spacing plates 1 to run smoothly. It is something to do.

In addition, the locking protrusion 5 portion is connected to the insertion hole 1 of the runner case 4.
Since it is thick enough to be inserted into the blind blade 7, even when the blind vane 2 is closed, the overlapping part will not become thicker than necessary.

Since this invention was exploited as described above, it is possible to attach the spacing plate to the runner case much more quickly and easily compared to the conventional spacing plate.
This is a very significant effect for this type of device, as it facilitates the opening and closing operations of the blind vanes and reduces the burden on the runner case.
