  The present invention relates to a booth that is used to keep only a limited necessary part in a clean atmosphere or a constant temperature atmosphere in order to perform various experiments and various operations that require a clean atmosphere and a constant temperature atmosphere such as assembly of electronic components. Is.

  Conventionally, as shown in FIGS. 6 to 9, the booth 50 includes four columns 52, a beam 51 connecting the upper portions of the columns 52, and a square or rectangular top plate 53 placed on the beam 51. The top plate 53 is provided with a suction fan F and a filter (not shown), and when used, a curtain 54 made of a synthetic resin sheet material for closing the opening between the columns 52 is attached. The booth space is maintained in a clean atmosphere by filtering the air in the external space sucked from the suction fan F into a purified air through a filter and blowing it out into the booth 50 as a downward flow (for example, Patent Documents). 1).

  When assembling the booth 50, as shown in FIG. 7A, first, two sets of U-shaped temporary assemblies 55 in which two columns 52 and 52 are connected by beams 51 are assembled, and these are erected. As shown in FIG. 7 (b), the columns 52 and 52 facing each other are connected by a beam 51.

Thereafter, the top plate 53 is placed on the top surface of the beam 51 and the auxiliary beams 51a and 51b divided into a lattice shape, and the curtain 54 is attached.
In this case, the top plate 53 is formed in a size divided into a lattice shape by the beam 51 and the auxiliary beams 51a and 51b, and as shown in FIGS. It is made to fix to the auxiliary beams 51a and 51b.
The curtain 54 is attached by sandwiching the upper end portion of the curtain 54 between the curtain retainer 54a and the beam 51, and fixing the curtain retainer 54a to the beam 51 with a fastener such as a screw, bolt, or nut.

  By the way, the conventional booth 50 has a problem that a curtain presser 54a and fasteners such as bolts and nuts are required for mounting the curtain 54, and the number of parts increases, and the assembly work becomes complicated and time is required.

In order to cope with this problem, as shown in FIG. 10, a method of attaching the curtain 54 to the beam 51 via a surface fastener 54b has been proposed.
However, in the case of the curtain 54 mounting structure using the hook-and-loop fastener 54b, dust is likely to adhere to the hook-and-loop fastener 54b, and dust is easily generated when the hook-and-loop fastener 54b is attached and detached, and air flows through the hook-and-loop fastener 54b. However, there was a problem that the sealing performance of the booth space was lowered.

  In view of the problems of the conventional booth, the present invention eliminates the need for fasteners such as screws, bolts and nuts, and hook-and-loop fasteners when installing the curtain, and can easily perform the curtain installation work in a short time. The purpose is to provide a booth.

  In order to achieve the above object, a booth according to the present invention is a booth comprising a column, a beam connecting the upper portions of the column, and a curtain for closing an opening between the columns. A curtain locking member made of an elastically deformable material is inserted into a loop portion formed by forming a groove and folding back the end portion of the curtain, and the curtain locking member is inserted together with the loop portion at the end portion of the curtain. It is characterized by being fitted into a groove.

The booth according to the present invention has a dovetail groove extending over the entire length of the column and the beam, and a curtain locking member made of an elastically deformable material is inserted into a loop formed by folding the end of the curtain. By attaching the stop member to the dovetail groove together with the loop portion at the end of the curtain, fasteners such as screws, bolts and nuts, and hook-and-loop fasteners are not required when installing the curtain. Work can be done easily and in a short time.
In addition, the curtain locking member is inserted into a loop portion formed by folding the end portion of the curtain and is not exposed to the outside, so that it is difficult for dust to adhere and prevent dust generation. Therefore, it is possible to improve the sealability of the booth space.

  Hereinafter, embodiments of a booth of the present invention will be described with reference to the drawings.

1 to 5 show an embodiment of the booth of the present invention.
Like the conventional booth, this booth 1 has four columns 2, a beam 3 that is connected to the upper portion of the column 2 via a bracket 6, and a square on which the lower end of the beam side is placed on the beam 3. Alternatively, it is composed of a rectangular top plate 5, and a suction fan F and a filter (not shown) are provided on the top plate 5, and when used, a synthetic resin sheet that closes the opening between the columns 2. The booth space is maintained in a clean atmosphere by attaching the curtain 4 made of a material, filtering the air in the external space sucked from the suction fan F through a filter to be purified air, and blowing it out into the booth 1 as a downward flow. Is.

  In addition to the colorless and transparent sheet material, the synthetic resin sheet material used for the curtain 4 is yellow when blocking ultraviolet rays, black when blocking light, and insect control depending on the use of the booth 1 Various sheet materials such as orange can be used.

The support column 2 and the beam 3 form a dovetail groove 10 (a groove having a shape in which the opening 10a is narrowed by forming an inward flange 11 along the groove) for attaching the curtain 4 over the entire length thereof. I have to.
In the present embodiment, as shown in FIGS. 2 to 3, the columns 2 and the beams 3 use aluminum molds having the same cross-sectional shape.
Accordingly, the struts 2 and the beams 3 can be obtained simply by cutting the aluminum mold having the same cross-sectional shape into a desired length, and the number of parts can be greatly reduced.

On the other hand, as shown in FIG. 4, the curtain 4 is configured such that the end of the curtain 4 is folded to form a loop portion 4a.
Then, a curtain locking member 7 made of an elastically deformable material is inserted into the loop portion 4a, and this curtain locking member 7 is formed on the support column 2 and the beam 3 together with the loop portion 4a at the end of the curtain 4. The dovetail groove 10 is fitted.
The loop portion 4a is not particularly limited as long as the loop portion 4a can be formed so as to have a space in which the curtain locking member 7 can be inserted. For example, FIGS. As shown, the end portion of the curtain 4 can be folded back and the folded end portion 4b can be heat-sealed.

  The curtain locking member 7 is elastically deformed when passing through the opening 10a of the dovetail groove 10, passes through the opening 10a, and returns to the initial shape when reaching the dovetail interior 10b. The shape, material, etc. are not particularly limited. For example, as shown in FIG. 4, a locking body in which flexible portions 73, 73 are formed symmetrically at the tip of a fixing portion 72 extending from a base 71. 70 and an elastic body 74 made of sponge packing or rubber packing as shown in FIG. 5C can be used.

  If the bracket 6 for connecting the column 2 and the beam 3 has a structure including an attachment hole 6b for attaching the column 2 on the side surface and an attachment hole 6d for attaching the beam 3 on the upper surface, its shape, The material or the like is not particularly limited. For example, as shown in FIG. 2, the side plate 6 a having a triangular shape in front view in which a plurality of mounting holes 6 b are drilled at the contact position of the support column 2 and the beam 3 are in contact with each other. It can be comprised from the molded object which provided integrally the upper surface 6c of the front view L shape which drilled the several attachment hole 6d in the location.

When assembling the booth 1, as shown in FIGS. 2 to 3, as shown in FIGS. 2 to 3, the support 2 is brought into contact with the side plates 6 a and 6 a of the bracket 6, and the ant for attaching the bracket 6 formed inside the support 2. A nut 12 is inserted and arranged at a position facing the mounting hole 6b formed in the side plate 6a of the bracket 6 in the dovetail inside 10b 'of the groove 10' (the shape is the same as that of the dovetail groove 10 for attaching the curtain 4). It is installed and fixed from the inside by a fastener 13 such as a bolt.
Similarly, a nut 12 is inserted and disposed at a position facing the mounting hole 6d formed in the upper surface 6c of the bracket 6 in the dovetail interior 10b ′ of the dovetail groove 10 for mounting the bracket 6 of the beam 3, and bolts are installed from the inside. It fixes with the fasteners 13, such as.

The above operation is performed on the brackets 6 at the four corners, and then the top plate 5 is placed on the top plate receiving portion 3 a formed inside the beam 3.
When the top plate 5 is stabilized by its own weight, it is not necessary to use a fixing means. However, a nut is inserted and disposed in a dovetail formed in the top plate receiving portion 3a and fixed when the bracket 6 is fixed. It can also be fixed in the same manner as the method.

Next, when the curtain 4 is attached to the column 2 and the beam 3, a curtain locking member 7 (70, 74) made of an elastically deformable material is inserted into a loop portion 4a formed by folding the end of the curtain 4. The curtain locking member 7 is pushed into the dovetail groove 10 formed over the entire length of the column 2 and the beam 3 to which the curtain 4 is attached, together with the loop portion 4a at the end of the curtain 4, as shown in FIG. Thus, the curtain 4 is fitted so as not to be detached from the dovetail groove 10 while being elastically deformed.
As a result, when the curtain 4 is attached, fasteners such as screws, bolts and nuts, and hook-and-loop fasteners are not required, and the attachment work of the curtain 4 can be performed easily and in a short time.
Further, since the curtain locking member 7 is inserted into a loop portion 4a formed by folding the end of the curtain 4 and is not exposed to the outside, dust is less likely to adhere and dust generation can be prevented, and the end of the curtain 4 can be prevented. Since it closely adheres to the support column 2 and the beam 3, the sealability of the booth space can be improved.

  When the curtain 4 is removed from the column 2 and the beam 3, the curtain locking member 7 is elastically deformed by strongly pulling the loop portion 4a of the curtain 4 to release the fitting state with the dovetail groove 10. 4 can be detached from the dovetail groove 10 together with the curtain locking member 7 inserted into the loop portion 4 a of the curtain 4.

  As mentioned above, although the booth of this invention was demonstrated based on the Example, this invention is not limited to the structure described in the said Example, For example, the support | pillar 2 and the beam 3 are restricted to the mold material made from aluminum. However, the configuration can be appropriately changed within a range not departing from the gist, such as made of synthetic resin.

  The booth of the present invention has the characteristic that when installing the curtain, fasteners such as screws, bolts and nuts, and hook-and-loop fasteners are unnecessary, and the curtain can be easily installed in a short time.
