Description

[Detailed Description of the Invention] The present invention relates to a curtain connecting device for making sheet shutters and the like used as doors in industrial structures such as garages, hangars, warehouses, factories, etc.

Conventionally, in order to create a single large-area flat surface using these sheet-like curtains, the width of the original fabric was generally 1200 mm.
Since it is in the shape of a band of about 1800 mm, this raw fabric is used by welding, gluing, sewing, or joining with bolts, screws, etc.

However, in the case of welding, adhesion, sewing, etc., the former cannot be attached or detached, and also lacks strength and durability when bolts, screws, etc. are used.

In view of the above-mentioned points, the present invention aims to solve this drawback by providing a connecting device that is detachable and has no problem in strength and durability.

An embodiment of the sheet-like curtain connecting device according to the present invention will be described in detail below with reference to FIGS. 1 and 2.

Reference numeral 1 denotes a connecting member consisting of a pair of molded materials 1a and lb. This connecting member 1 can be divided, and the molded materials 1a and lb
When combined, grooves 3 and 4 are formed in the longitudinal direction at both ends to accommodate the thickness of the sheet-like curtain 2.

In addition, each of the shapes 1a and lb has horizontal receiving pieces 5, 5 extending inwardly at intervals on the side surfaces, and furthermore, these receiving pieces 5,
5 is provided with retaining protrusions 6, 6 for engaging when assembled, and the shapes 1a and 1b are assembled facing oppositely so that the engaging protrusions 6, 6 face each other when assembled. .

The sheet-like curtain 2 has an enlarged part 2' by enlarging both end edges with rods 7, and the enlarged part 2' of the sheet-like curtain 2 is formed by combining the shapes 1a and lb. The connecting member 1 is inserted into the inner side of the connecting member 1 through the grooves 3 and 4 formed at the time, and then the shapes 1a and 1b are slightly shifted while engaging and locking the engaging protrusions 6, 6. A rod 9 such as a round tube that fits the gap 8 between the receiving pieces 5, 5 is inserted into the gap 8 to prevent splitting and sequentially connect the curtain body 2 to create a wide area suitable for a sheet shutter, etc. They are connected so as to form a flat surface.

Also, the curtain 2 between the connecting members 1 and 1 (i.e. between the edges of the curtain 2)
Attach one or more bag-shaped insertion bags 10 to the case, insert the core material 11 into the insertion bags 10, and extend the both ends from the curtain body so that the case 12 is placed on the top, as shown in FIG. Fit the rails 13.1 into the provided left and right guide rails 13.13.
3.

Figures 3 to 6 show sheet shutters connected together to form a sheet shutter A, which is applied to this sheet shutter A. Bearing pieces 14 and 14 are provided in the case 12 provided at the top, and this bearing A shaft 16 on which a winding drum 15.15 is arranged is horizontally supported on the piece 14.14, and this shaft 16 is also connected to the opening/closing machine 1.
Connect to 7.

The winding drum 15.15 is connected to the bottom part 18 provided on the lower end side of the sheet shutter A by a belt or wire rope 19, suspends the sheet shutter A, and operates the opening/closing device 16 to move the sheet shutter A along the guide rail 13. Core material 1
1 is raised, and the hanging sheet shutter A is pulled up and folded as shown in FIG.

20 is a guide car.

As described above, the present invention combines a pair of shapes 1a, lb in opposite directions and engages the engaging protrusions 6, 6 of receiving pieces 5, 5 stretched from the sides of the shapes 1a, lb. , receiving piece 5,
A rod 9 is inserted into the gap 8 of the main body 1 to lock the shape and prevent the shape from splitting. Since the main body 1 is assembled by positioning the enlarged part 2' provided at the end of the curtain body 2 through the opening 2 in the main body 1, the curtain body 2 can be completely joined without coming off. When removed, the main body 1 is divided and the curtain body 2 is detachable, so the curtain bodies can be easily and securely connected, and even if a part of the curtain body is damaged, that part of the curtain body can be removed. 2 can be easily replaced by dividing the connecting member, which is convenient.

Since the shapes of the connecting member 1 can be reversed, the mold can be made in one part, which is convenient, and mass production is possible.

Furthermore, since they can be connected on-site, they can be transported in parts and can be connected without damaging the curtain body.
