JPS5840959Y2 - Mounting support for external air shielding curtains - Google Patents

Description

[Detailed description of the invention] This invention is an outside air shield that is installed between a curtain that is installed at the entrance of a refrigerated warehouse, etc., and blocks the inflow and outflow of air from inside and outside, and a support rod from which this curtain hangs. This invention relates to a mounting support for curtains.

Conventionally, at entrances and exits of warehouses and the like where forklifts frequently come and go, heavy opening/closing doors have been left open, allowing dust, rain, snow, insects, etc. to enter.

Therefore, it was almost impossible to install air-conditioning and heating equipment that needed to be isolated from the outside world, and it was also impossible to isolate outside noise.

In view of this, for example, air curtains have been developed that are easy to move around and have a high degree of isolation from the outside world, but they have the disadvantage of being expensive to run and not being sufficiently effective in strong winds. was there.

In the past, hanging curtains similar to the present invention have been developed, but they all have a crude structure in which a band-shaped member such as vinyl is enclosed with a long flat bar or angle. It was inconvenient to replace the strip member, and since the flat bar or angle and the strip member were fixedly attached, the parts were subject to severe fatigue and were easily damaged.

There is also an improvement on the universal door disclosed in Japanese Utility Model Application No. 49-130641, but in this case, the central part of the band member is made thinner and both edges are formed into ribs, which makes it difficult to mold. Since the core metal is embedded in the rib, many manufacturing steps are required, and there is a regret that it cannot be provided at a low price.

Further, the support has an annular portion, the annular portion is inserted into the support tube, and the lower part of the annular portion extends downward to form two legs, and the sheet of the strip member is inserted between the legs. The shaped parts are clamped and tightened with bolts.

Therefore, when installing this flexible door, it was necessary to insert the required number of supports from the end of the long support tube in advance, or if the strip member became dirty or damaged, the supports Since it cannot be easily separated from the support tube, there is a drawback that it takes time to replace it.

As a result of intensive research considering the drawbacks of the existing curtains mentioned above, the inventor first developed a hanging type curtain (approx.
-106627).

A mounting support for hanging and mounting this curtain on a support rod is composed of a pair of mounting members 1 having the same shape, as shown in FIG.

That is, the mounting member 1 is a support rod 2 stretched over the mounting base 7.
It consists of a semi-cylindrical body 3 that surrounds about half the outer circumference of the semi-cylindrical body 3, and a clamping plate 4 that extends downward from one side edge of this semi-cylindrical body 3,
The mounting members 1 are made to face each other to constitute a mounting support.

Therefore, the pair of semi-cylindrical bodies 3 press and hold the support rod 2, and the pair of clamping plates 4 press and hold the overlapping portion of the curtain material 5, respectively.

The crimping is carried out using the through holes formed in the clamping plates and the perforations in the curtain material 5 (
This is done by means of a bolt 6 which is inserted into the hole (not shown).

In the figure, 8 is a fixing tool for attaching the support rod 2 to the mounting base 7, and 9 is a locking piece.

However, in the mounting support according to the above invention, the support rod 2
The attachment part to the semi-cylindrical body 3 is the support rod 2.
It cannot be locked in.

That is, since the mounting support is supported by the support rod 2 only after the pair of mounting members 1 are butted against each other, the support rod 2 of the mounting support is
The installation of the curtain material 5 must be carried out by at least two workers from both sides of the curtain.

Therefore, the conventional mounting support has a problem of extremely poor workability.

The present invention focuses on the problems of the above-mentioned invention, and aims to provide a mounting support for an outside air shielding curtain that is easy to install.

In order to achieve this purpose, the mounting support according to the present invention consists of a support body and a crimping piece, and the support body is a cylindrical body with a slit slightly narrower than the diameter of the support rod, and the slit extends to the side edge. and a clamping plate facing the curtain, and the crimp piece is composed of a curved plate covering the slit and a clamping plate extending from one side edge of the curved plate and similar to the clamping plate of the main body. , so that only the support body can be attached to the support rod.

Embodiments of the mounting support for an outside air shielding curtain according to the present invention will be described in detail below with reference to the drawings.

FIG. 2 shows a mounting support according to this embodiment.

As shown in this figure, the mounting support 10 includes a support main body 1
2, and a crimp piece 14 that pairs with the support body 12.

The support main body 12 has a cylindrical body 16, and this cylindrical body 16
has a size that can be fitted onto the outer periphery of a support rod for hanging a curtain, which will be described later.

A slit 18 opening in the longitudinal direction is formed in the cylindrical body 16.

The opening width of this slit 18 is slightly narrower than the diameter of the support rod to be attached, and is adjusted so that the support rod can be inserted into the cylindrical body 16 and will not come off after insertion.

Therefore, the cross-sectional shape of the cylindrical body 16 is larger than the circular arc of the cylindrical body 16, and is preferably formed in a substantially positive circular arc shape.

Further, a clamping plate 20 is provided extending downwardly over one side edge of the slit 18 of the cylindrical body 16.

This clamping plate 20 is a rectangular plate piece, and the surface on the slit 18 side faces one surface of the curtain to be attached.

Furthermore, the lower edge of the sandwiching plate 20 is bent outward to form a flared portion 22 .

On the other hand, the crimp piece 14 paired with the support main body 12 is provided with a curved plate 24 that can cover the slit 18 formed in the cylindrical body 16 of the main body 12.

This curved board 24 is curved with the same curvature as the cylindrical body 16, and when assembled to the support main body 12, the cylindrical body 1
6 and can surround the support rod.

The clamping plate 2 of the main body 12 is attached to one side edge of the curved plate 24.
A rectangular clamping plate 26 similar to that shown in FIG.

This clamping plate 26 is also provided with a flared portion 28 bent outward.

The mounting support 10 consisting of the support main body 12 and the crimping piece 14 is supported on a support rod, and a curtain is attached to it.
2.26 It is crimped and supported between the clamping plates 20 and 26 by tightening the bolt 32 and nut 34 that are inserted into the through hole 30 bored in the other side.

For this, the curtains are provided with perforations.

FIG. 3 shows a case where a curtain is attached using such an attachment support 10.

As shown in this figure, the mounting support 10 is attached to a support rod 38 that is suspended horizontally on a mounting base 40 such as a doorway doorway through a bracket 36, and a rectangular curtain material 40 made of transparent vinyl or the like is attached adjacent to the support rod 38. The overlapping portion where the side edges are overlapped is held between the clamping plates 20 and 26, and the bolt 32 is
The curtain is formed by inserting the

A locking ring 39 is interposed between each mounting support 10 to prevent the mounting support 10 from shifting to the left or right.

According to the mounting support 10 configured in this way, in advance,
When the support main body 12 is attached to the support rod 38, the main body 12 will not come off the support rod 38 because the slit 18 is narrower than the diameter of the support rod 38.

Therefore, after mounting the main body 12, the overlapping portion of the curtain material 40 is applied to the clamping plate 20 of the support main body 12, and the bolt 32 is inserted and tightened using the crimp piece 14, and the work is completed.

Since this series of installation work can be fully performed by one person with a working tool, the workability is extremely improved.

Further, in particular, since the curved portion 24 of the crimp piece 14 covers the opening formed by the slit 18, it is possible to reliably prevent the crimp piece 14 from falling off from the support rod 38.

As described above, the mounting support according to the present invention has the effect of extremely high workability.
