Description

[Detailed description of the invention] This invention relates to a device for supporting the horizontal slats of a blind.The purpose of the present invention is to provide a lateral slat supporting device that can raise and lower the blind smoothly and reliably. It is a unique ingenuity.

That is, to summarize the present proposal, a hanging metal fitting in which each end of a plurality of vertically connected connecting bodies is pivotally connected to each other by a shaft pin,
The shaft pins of the two opposing hanging fittings are pivoted and connected to the side ends of the horizontal slats with their axes facing parallel to each other, and the connecting body is connected to the upper arm body. The lower arm body is bendably connected to the lower arm body by a connecting pin that slides in a vertical hole bored in the lower part of the upper arm body or the upper part of the lower arm body, and the lower arm body has a connecting pin in the lower part of the upper arm body. It has a protrusion that protrudes in the direction in which the body bends and protrudes, and is located above the longitudinal hole, the lower surface of the protrusion is formed as an upward slope, and the upper part of the lower arm body includes: The present invention is characterized in that it includes a guide portion that slides in contact with the lower surface of the protrusion.

Hereinafter, the present invention will be explained based on the illustrated embodiment.
As shown in the figures to FIG.
Each hanging fitting is a plurality of connecting bodies a, l), c... arranged in a vertical line.
・The ends of each are connected together by a shaft pin 2, and
Each of the connected bodies a, l), c, . . . is formed as the same structure.

This connecting body a consists of an upper arm body 3, a lower arm body 4, and a connecting pin 5. The upper arm body 3 formed in a long plate shape has a vertically elongated hole 7 bored in its lower part. A protrusion 6 is formed on the edge above 7, and when the connecting body a is folded, the connecting portion of the upper arm body 3 and the lower arm body 4 protrudes from this protrusion 6 as described later. The protrusion 6 is provided to protrude in the direction of the refraction protrusion, and the lower surface A of the protrusion 6 is formed as an upward slope.

The lower arm body 4 has long plates 9, 9 facing each other at a constant interval,
It consists of an inclined side piece 13.13 that projects on the same side as the projection 6 at the tip of each long plate 9°9, and a connecting piece 1 that connects the upper ends of both inclined side pieces 13.13. The lower arm body 4 is formed by bending a single plate, and the connecting piece 1 serves as a guide portion 10 that comes into contact with the lower surface of the protrusion at the lower part of the upper arm body.

Then, the lower part of the upper arm body 3 is inserted between the upper ends of the opposing long plates 9, 9 of the lower arm body 4, and both ends of the connecting pin 5 sliding in the long hole 7 are inserted between the long plates 9, 9. The upper arm body 3 and the lower arm body 4 are connected in a bendable manner.

The hanging fittings A face each other at a constant interval, and it is preferable that this interval is maintained at the length of the bent connecting body a so that the opposing connecting bodies do not collide with each other.

Further, the shaft pins 2, 2 of the opposing hanging fittings A, A are opposed to each other with their axes parallel to each other, and the rain fittings A
, A are all oriented in the same direction.

The hanging fittings A facing each other in this way, the opposing shaft pins 2 of A,
The side end of the horizontal blade plate 12 is pivotally attached to the side blade plate 2, and the horizontal blade plate 12 is connected to the opposing shaft pins 2, 2 via a mounting piece 30 attached to the side end.

In this way, the plurality of horizontal blades 12 are pivotally connected to the vertically connected opposing shaft pins 2, 2, and are suspended and supported.

Note that the notch 8 formed at the lower edge of the upper arm body 3 is the fourth
As shown in the figure, this is for storing the protrusion 6 of the connecting body that is connected to the lower end of the connecting body a when the connecting body a is folded.

Further, as shown in FIG. 5, the guide rollers 15 protruding from each shaft pin 2 of one of the hanging fittings A are integrally attached to a short blind frame 16 attached to the side of the horizontal blade plate 12. It slides in the formed groove 17 to not only allow the blind to open and close smoothly, but also to prevent the blind from swinging or shaking due to wind and rain.

When the blind raising/lowering paper 14 fixed to the lower end of the hanging bracket A is raised, the connecting pin 5 moves upward in the elongated hole 7 together with the lower arm 3, and the guide body 1
0 slides obliquely upward on the lower surface A of the protrusion, the connecting portion of the upper arm 3 and the lower arm 4 protrudes in the direction in which the protrusion 6 protrudes, and the connecting body A is folded.

Further, in this embodiment, since the connecting body a has the notch 8 that accommodates the protrusion 6, the hanging metal fitting A can be folded without adding bulk.

As shown in FIG. 5, the blind is attached to the outdoor side of the sash, and this is because it is used as a blind that also functions as a shutter or shutter.

The short frame 16 attached to the outdoor side of the building is
A separately formed tip frame 19 is attached to the outdoor side of the base frame 18 that is fixed to the building frame.
The base end frame 19 is a hollow extrusion-molded member, and the base end frame 19 has a locking piece 20 protruding toward the outdoor side on the blind-side indoor exterior surface of the base end frame 19. A locking groove 21 having an opening facing the opposite side of the blind is provided on the outdoor surface of the blind.

The tip frame 19, which is extruded into a hollow shape, has the groove 17 in the part facing the blind, and the interior surface of the tip frame 19 has an overlapping piece 22 that abuts the locking piece 20. The distal end frame 19 and the proximal end frame 18 have a hook piece 23 that is locked in the locking groove 21, and the hook piece 23 is locked in the locking groove 21, and the short frame 16 is The locking piece 20 and the overlapping piece 22 are connected by screwing from the blind side.

Now, when installing the blind, please make sure that the tip frame 19
is removed from the base end frame 18, and the blind is placed and fixed on the upper end of the base end frame 18 from the front side on the outdoor side.Then, the guide roller 15 is fitted into the groove 17, and the front end frame 19 is removed from the base end frame 18. It is only necessary to attach the blind to the end frame 18, and when removing the blind, there is no need to remove the entire formwork 16 from the building frame; simply remove the tip frame 19 from the base frame 18, and the blind can be easily removed. Can be removed.

As described above, the present invention allows the connecting body to be folded and expanded smoothly and reliably, so that the blind can be raised and lowered smoothly.

The present invention is not limited to the above-mentioned embodiment, but also includes a case in which a long hole into which the connecting pin slides is provided in the upper part of the lower arm body instead of providing it in the upper arm body. Both of the opposing connecting bodies are bent and folded in the same direction, but the present invention is not limited to this, and the above-mentioned protrusions are turned to opposite sides and the hanging fittings are faced, so that the connecting bodies are folded in opposite directions. It can also be bent and folded.
