Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double cell honeycomb bonding structure suitable for window covers and the like. In particular, the invention is
Double-cell honeycomb combined structure in which a plurality of horizontal double-cell honeycomb structures formed by folding continuous lengths of refractable material into an 8-shaped cross-sectional shape are vertically stacked and joined together to form three rows of cells Regarding

[0002]

2. Description of the Related Art There are various conventional examples of a honeycomb structure made of a foldable material. For example, U.S. Pat. Nos. 4,450,027 and 4,603 to Corsen.
Nos. 072 and 4,631,108 disclose honeycomb structures in which a tubular body is formed by folding a continuous length of foldable material as individual cells by partially overlapping diametrically opposite edges. Also, U.S. Pat. No. 4,677,012 to Anderson discloses a honeycomb formed from a continuous length of foldable material secured to a separate plate material by folding the longitudinal ends over one edge of the material. The structure is disclosed. Also in this patent, the cells are formed one by one and the plate material is separately required. Also, U.S. Pat. No. 4,631,217 to Anderson discloses a honeycomb structure formed from a Z-folded continuous length foldable material. In this patent, the front surface of each cell is constructed of one material and the back surface is constructed of another material, with each material extending from one cell to another. In any case, each cell is made of two halves of two materials.

[0003]

The above-mentioned conventional example has a problem that the productivity is low and the quality control of the product is relatively difficult. For this reason, in U.S. patent application Ser. No. 08 / 346,045 filed Nov. 29, 1994 (assigned to the applicant), a double cell honeycomb structure made of a continuous length of refractable material and folded into a vertical 8-shape. In, the plurality of double cell honeycomb structures are stacked and bonded to each other to form a window cover having one cell row. It is usually necessary to have a plurality of cell rows in order to improve the optical / thermal insulation characteristics and the dimensional durability.

In US Pat. No. 4,307,768, an energy saving insulation window shade is an energy saving insulation consisting of a plurality of parallel hollow channels formed by a plurality of initially parallel layers and joined along the edge of the shade. I am proposing a window shade. This sunshade has a problem in that the joining line is exposed and always has a dull appearance, which is clearly undesirable for use as a window cover.

DESCRIPTION OF THE PREFERRED EMBODIMENTS First, a window cover 1 will be described with reference to FIG. 1 of the accompanying drawings. The window cover 1 includes a plurality of honeycomb structures 2 which are arranged in parallel in parallel with each other to form cells in three rows.
(Described later), upper rail 3, lower rail 4 and tension cord 5
Consists of.

As shown in FIG. 2, in the first embodiment according to the present invention, one unit of the double-cell honeycomb structure 2 has a continuous length of a bendable material (fibrous material such as paper, spun fiber, etc.). Material). This material is vertically folded so that it has a horizontal 8-shaped cross-section, that is, each hexagonal cell is doubled and that the inflections are invariably equidistant. That is, in this embodiment, 14 refracting portions 11, 12, 13, 14, 15, 16, 17, 1 are provided.
There are 8, 19, 20, 21, 22, 23, 24, and the same length portion between adjacent refraction portions 11, ... 24 is 12
I can do it. These form two cells 25 and 26 which are horizontally parallel and symmetrical to each other. First bend 11
And both ends 2 of the refractable material outside the last bend 24
7 bends in the opposite direction to each other and two cells 2
It is joined to a horizontal intermediate (connecting) portion 28 between 5 and 26.

A plurality of horizontal double cell honeycomb structures 2
3 has its left cell 25 aligned above another similar left cell 25, while the upper right cell 26 is shown in FIG.
Are stacked vertically and glued to each other to align cells 25 and 26 on top of another similar right cell 26.
Form a cell row of. At the same time, the central cell 29 is formed by two adjacent double cell honeycomb structures. The central cell 29 has two tilted bending portions (sides) connected to the horizontal middle portion 28 of one structure at the bottom and two tilted bending portions (sides) connected to the corresponding horizontal middle portion 28 of the other structure at the top. It is defined by the bent portion (side). Thus, the central cell 29 is formed between the left and right cells 25 and 26. In this way, a three-row honeycomb bonded structure including the cells 25, 26, and 29 is completed.

FIG. 4 shows a second embodiment of the present invention. This second embodiment is substantially similar to the first embodiment described above. However, the difference is that the two inner inclined refraction portions (sides) of each of the two cells 25 and 26 are slightly shorter than the two outer inclined refraction portions (sides). By doing so, when the honeycomb combined structure is extended to the longest as shown in the figure, that is, when the two inner inclined refraction portions (sides) of the two cells 25 and 26 are straight, the two outer sides are formed. The inclined refraction part (side) of the refraction part line 1 remains inclined and refracted.
4 and 21 are permanently secured.

FIG. 5 shows a third embodiment of the present invention. In the third embodiment, instead of the horizontal intermediate portion 28, one of the inner inclined refraction portions (sides) of one cell 25 and one of the inner inclined refraction portions (sides) of the other cell 26 facing each other are provided. It is replaced with a connecting portion 28 'to be connected. This connecting portion becomes an oblique straight line. A continuous length birefringent end 27 of refractable material is joined to the angled connecting portion 28 '.

FIG. 6 shows a fourth embodiment of the present invention. This fourth embodiment is substantially similar to the third embodiment above. However, the terminating portion 27 is different in that it is refracted inward as opposed to the refraction outside the terminating portion 27 shown in FIG. The terminations 2 of the first and second embodiments shown in FIGS. 2, 3 and 4.
It is also possible to refract 7 inward.

As used herein, the term "honeycomb" is to be interpreted broadly to mean ordinary bonded cells and may be polygonal shapes such as hexagons or rectangles, or variations thereof.
