Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a scratch prevention device for a panel shutter.

[Prior Art] First, the panel shutter will be briefly described with reference to FIGS. 4 to 6. The upper ends of both sides of each panel 1 are attached to an opening / closing chain 2 via pins, and the chain 2 is driven by a motor 3. It is wound around the hoisting and lowering sprocket 8. still,
In the figure, 4 and 6 are sprockets, 5 and 7 are chains, and 10 is a brightening window.

When the shutter is opened, when the hoisting and lowering sprocket 8 in FIG. 6 is driven clockwise by the motor 3, the open / close chain 2 is hoisted and the respective panels 1 are also hoisted. In the panel 1 which has passed over the hoisting and lowering sprocket 8, rollers (not shown) provided on the upper ends of both side surfaces of the panel come into contact with the tilt guide 9, and the panel 1 moves along the tilt guide 9 and the tilt guide 9 It is stored in a posture suspended from the.

When closing the shutter, the hoisting and lowering sprocket 8 is driven in the counterclockwise direction so that the opening / closing chain 2 is drawn out, descends following the movement of the opening / closing chain 2, and the shutter is closed.

[Problems to be Solved by the Invention] In the panel shutter described above, when the panel 1 is stored, it moves along the inclined guide 9 as shown in FIG. Since the upper end of the panel 1 is supported and suspended, the panels may slide against each other when the panels are stored, and scratches may occur on the panel surface.

Since such a scratch damages the appearance of the panel shutter and affects the life of the product, it must be prevented as much as possible.

In view of the above situation, the present invention is intended to prevent the panels from directly contacting each other when the panels are stored and to prevent the panels from sliding on each other and causing scratches on the surface.

[Means for Solving the Problems] According to the present invention, a plurality of panels are connected by a chain, and the chains are hoisted and lowered to open and close. To store the panels, rollers provided on the upper ends of both side surfaces of the panel are used as inclined guides. In a panel shutter in which the tilt guide guides the panel to the storage position and the tilt guide hangs the panel, the panel shutter hangs between the upper panel lower end surface and the lower panel upper end surface. A string-like flexible cushioning material is provided, and the cushioning material is pulled out from the lower panel upper end surface by the separation between the upper panel lower end surface and the lower panel upper end surface, and the cushioning material moves the panel in the plate thickness direction. It is characterized in that it has a length sufficient to allow polymerization.

[Operation] When the panels are stored, the cushioning material is interposed between the panels, and the panels do not come into direct contact with each other, so that the generation of scratches is prevented and the noise caused by the collision between the panels is also suppressed. To be done.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a perspective view of a state in which the panel 1 is hung by the opening / closing chain 8 at the time of hoisting and lowering, and is bent to a required position on the lower end surface of the panel 1 or to a required position in the width direction. The free and stretchable string-like cushioning material 11 is hooked at its upper end and hung down, and the string-like cushioning material 11 is inserted into the upper end surface of the lower panel 1, and the lower end is the lower surface of the lower panel 1. To reach. A weight 12 is fixed to the lower end of the string-shaped cushioning material 11 with the string-shaped cushioning material 11 inserted therethrough.

 Next, the operation of the embodiment will be described with reference to FIG.

FIG. 2 shows the storage state of the panel 1. When the upper and lower panels 1 and 1 are separated from each other and the lower end surface of the upper panel and the upper end surface of the lower panel are separated from each other, the string-like cushioning material 11 is pulled out from the lower panel and drooped from the inclined guide 9 in a stored state. In this case, since the panels are sequentially overlapped in the horizontal direction, the string-shaped cushioning material 11 insertion portion provided between the upper end surface and the lower end surface of the adjacent panels is pulled out and the panel 1 is inserted.
And the back surface of the panel 1 adjacent thereto. Therefore, the panels 1 and 1 are not in direct contact with each other, and it is possible to prevent the panels from sliding on each other and causing scratches on the panel surface. Furthermore, the string-shaped cushioning material when stored
Since 11 is interposed between the panels, noise due to the collision between the panels can be suppressed.

In addition, when closing the shutter, the panel 1 is moved from the stored state.
When the panel is extended, the panels 1 are vertically aligned, and the upper panel lower end surface and the lower panel upper end surface approach each other, but at that time, the weight 12 moves the lower end of the string-like cushioning material 11 downward. Since it is pulled, the excess string-like cushioning material 11 is stored inside the lower panel 1 and does not overflow.

As described above, the string-like cushioning material 11 does not hinder the opening / closing operation of the shutter in any way, and effectively prevents the panels from sliding on each other in the stored state.

FIG. 3 shows another embodiment of the present invention, in which a strap-shaped buffer 13 bent in a bellows shape is provided between the lower end surface of the upper panel and the upper end surface of the lower panel. The strip-shaped buffer 13 is expandable and has a restoring force to the bent state.

Also in this embodiment, in the retracted state, as in the case shown in FIG. 2, the band-shaped cushioning body 13 is interposed between the panels to prevent the panels from sliding with each other, and when the panel 1 is vertically aligned, Due to the restoring force of the belt-shaped cushioning body 13 itself, the panel 1 is shortened.
Is housed between the lower end surface of the and the upper end surface of the lower panel 1.

It should be noted that the present invention is not limited to the above-described embodiment, and the shape and material of the cushioning material, such as the string-like cushioning material 11 described above being one continuous string, does not depart from the gist of the invention. It goes without saying that various changes can be made in the range.

[Advantages of the Invention] As described above, according to the present invention, since the cushioning material can be interposed between the panels when the panels are stored, it is possible to prevent the occurrence of scratches due to the sliding of the panels and to store them. It is possible to exert an excellent effect that it is possible to prevent generation of noise due to collision between panels at times.
