Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> This invention relates to a winding shutter.

<Prior art> Horizontally slatted plates are flexibly connected one after another to form a partition door, and when the door is opened, the winding shutter is wound around the take-up shaft. . Therefore, when wound on the peripheral surface of the winding shaft, the number of slat plates increases as the outer layer increases in winding diameter.
Further, the relational position between the slat plate of each winding layer and the slat plate of the outer winding layer is indefinite.

<Problems to be solved by the invention> It is preferable that a pattern or a picture is drawn on the shutter when the shutter is lowered in a store or the like. However, each time the shutter is rolled up, the pattern or picture is subject to shock and friction due to the inner and outer slat plate connections. for that reason,
Measures have been taken such as making the slat plate thin, making the connection part free of corners, and using paint that is not easily damaged. Also, the slat plate is made of transparent material,
There are some that allow the inside of the store to be seen through from the outside when the shutter is lowered, but when used, the surface of the slat plate is also scratched by friction and the transparency is deteriorated.

The inventor of the present invention has taken up the problem not to take such measures, but to fundamentally eliminate the impact and friction on the slat plate surface when the shutter is wound.

<Means for Solving the Problems> In the winding shutter of the present invention, laterally long slat plates are connected one after another by the same-shaped connecting member to flexibly extend and retract to form a partition door, which is wound around the winding shaft when opened. In the winding shutter, when the shutter is wound around the winding shaft, only the slat plate connecting member that is the innermost layer is equipped with a step that is thick enough to float the connected slat plate from the winding shaft peripheral surface. That is, the slat plate connecting member of each winding layer is placed on each radiation that equally divides the circumferential surface of the winding shaft in the circumferential direction, and the number of slat plates in each winding layer from the innermost layer to the outermost layer is the same as the circumferential direction. The fixed number is the same as the fraction, and the connecting members are made thicker than the slat plates so that the slat plates at each position and layer can float in parallel with each other. The features.

<Operation> In this invention, a series of slat plates constituting the shutter are gradually increased in length in the winding direction from the one close to the winding shaft. Specifically, when wound on the winding shaft peripheral surface, the number of slat plates in each winding layer from the innermost layer to the outermost layer becomes equal, and at each position on the winding shaft peripheral surface,
The slat plates of each winding layer should overlap in parallel. It is easy to see by drawing it, but radiation that equally divides the angle of 360 ° around the winding shaft is drawn, and a slat plate connecting member stacked on the outer circumference of the winding shaft is drawn on each radiation. If you draw each slat plate that connects those connecting members, you can find the length of the slat plate in each layer in the winding direction.
The dimensions are the same, but the connection type does not matter.

<Embodiment> FIG. 1 is an explanatory view of an embodiment of the present invention, in which the slat plate is 1, the connecting member is 2, the winding shaft is 3, and the length of one slat plate in the winding direction is a or b. I have to.

In FIG. 4, one slat plate 1, one connecting member 2, and a slide ring 4 fitted on the protruding shafts 2a at both ends of the connecting member 2 are separately shown. It goes without saying that the pulley 4 enters the shutter rail (not shown).

Round bar parts 1c on both edges of the slat plate 1 of FIG.
When the slat plate 1 is fitted in the round grooves 2b on both sides of the connecting member 2, the slat plate 1 can be rotated by the amount that the opening surface of the round groove 2b is open.
As a result, it is possible to hang it straight as shown in FIG. 1 or to roll it by winding it around the winding shaft 3.

However, the connecting member 2 does not necessarily mediate such a long rod-like member, but may be an interlocking type in which the winding portion of one edge of the slat plate 1 has the insertion portion of the other edge, or a flexible engagement. Even the armor type connected by a ring does not prevent the application of this invention.

FIG. 3 shows a state in which the slat plate 1 of FIG. 4 is attached to both sides of the connecting member 2, and the outlet of the circular groove 2b of the connecting member 2 is crushed so that the slat plate 1 does not move left and right.

A feature of the present invention is that the shutter connecting member 2 wound around the winding shaft 3 overlaps on each position where the circumferential surface of the winding shaft 3 is equally divided in the circumferential direction as shown in FIG. FIG. 2 is an enlarged view showing a state in which 1 overlaps with each other in parallel. Only the innermost layer connecting member 2 directly mounted on the peripheral surface of the winding shaft 3 is
Although the steps 5 are attached at various places in the longitudinal direction, all the other connecting members 2 have the same shape. The shape of the connecting member 2 is preferably a cross section suitable for overlapping one after another.

FIG. 2 together with FIG. 5 show a method for obtaining the length in the winding direction of each slat plate 1 by drawing.

In this embodiment, since six slat plates 1 make one round around the winding shaft at the time of winding, first, as shown in FIG. 5, radiation is obtained by dividing the cross section of the winding shaft 3 into six equal parts. Draw the shutter attachment point A easily at the intersection with the peripheral surface. This attachment point A
Starting from, draw a regular hexagon with corners on the radiation. When the winding shaft 3 has a circular peripheral surface, it is a regular hexagon that does not touch the circle. Each side suggests the position and length of the slat plate. That is, a regular connecting member 2 is drawn at each corner of the regular hexagon as shown in FIG. 2, and the slat plate 1 between them is also drawn. In this example, the diameter of the winding shaft is 150 mm, and the dimension C of the connecting member 2 in FIGS. 2 and 4 is constant at 15 mm, and the length a or b of the slat plate 1 in the winding direction is from 64 mm of the lowermost layer to 80 mm. , 94, 108, 122 mm and increased layer by layer.

In FIG. 5, the connecting member 2 is depicted as a triangle in a very simple manner, but slat plates connecting them are shown as 1a, 1a ', 1b, 1
Explain b '.

Six innermost slat plates 1a are included, and five of them have the same size, but the sixth 1a 'transferred to the second layer is slightly longer than the others. Similarly, the five slat plates 1b of the second layer have the same size, and the sixth slat plate 1b 'is slightly longer. It is necessary to pay attention to this point and calculate the plate size from the drawing. The sixth sheets of each winding layer are parallel to each other.

Although one embodiment has been described above, the present invention can be variously changed and applied without changing the gist of the invention, depending on the working conditions and the ingenuity of the designer. Even if the slat plate has a curved surface, the connecting member can be used. Even if the hinge material is not used, it is sufficient to draw and design so that the connecting members are stacked and the slat plate surfaces float in parallel.

<Advantages of the Invention> The winding shutter of this invention does not apply the winding impact or friction to the slat plate as in the conventional case, only the connection members are placed on each other during winding. Therefore, the slat plate is easier to manufacture because it can use a wider one without being as fine as the conventional one, but the biggest advantage is to make the surface of the slat plate a beautiful mirror finish, pattern,
This means that there is no risk of damage even if the picture is drawn with soft paint.
