Description

  The present invention relates to a shielding device.

  As a conventional shielding device, there is one disclosed in JP 2010-77709 A (Patent Document 1). In the shielding device disclosed in the same document, a curtain is formed by resin coating any one of fabric, nonwoven fabric, paper, and a synthetic resin sheet material, and linear folding lines are respectively formed on the bellows-like folded portion of the curtain. Engrave. Then, the number of intermediate runners fixed to the upper middle part of the curtain is set to 1 to 4 per 1 m of the curtain length, the two curtains are arranged in parallel, and a plurality of connecting plates are provided between the curtains. It is a double curtain type accordion door.

  According to this, the folding pieces of the curtain can be brought into close contact with each other by folding and folding can be performed thinner than before, so that the front opening of the door opening can be widely used. Also, by reducing the number of intermediate runners to 1 to 4 per 1 m of curtain length, the curtains can be folded thinly without causing the runners to contact each other when the curtains are folded. There is an effect that convenience at the time of passing through the opening is further increased.

JP 2010-77709 A

  However, when two curtains are arranged in parallel as in the conventional shielding device, the curtains need to be connected by a connecting plate. For this reason, in the conventional shielding apparatus, there existed a subject that productivity was bad and led to a cost increase.

  Therefore, the present invention has been made in view of such a problem, and the object of the present invention is to achieve excellent productivity and cost reduction in a shielding device in which two shielding materials are arranged in parallel. It is in.

  In order to solve the above-described problems, according to the present invention, one rail provided with a plurality of suspension means, a first shielding material that is suspended by the suspension means, and opens and closes along the rail, and a second And the first shielding material and the second shielding material are open / close directions of the first shielding material and the second shielding material (extension of the first shielding material and the second shielding material). And the plurality of suspension means include a first suspension means for suspending the first shielding material and a second suspension means for suspending the second shielding material. The shielding apparatus characterized by including these is provided.

  According to such a configuration, the two front and rear shielding materials are simply suspended by one rail, that is, the suspending means on the same straight line, and there is no need to connect the front and rear shielding materials. In this way, the shielding device has excellent productivity and cost reduction. Further, since an air layer is formed between the two front and rear shielding materials, the heat insulation performance is enhanced. Moreover, since the front and rear shielding materials can be arbitrarily selected and combined, the degree of freedom as interior is improved.

  The present invention can be applied in various ways. The following application examples can be combined as appropriate. For example, the first suspension means and the second suspension means may be alternately arranged on the rail. According to such a configuration, since the two front and rear shielding materials are suspended at a constant interval, the state of the heel of the two front and rear shielding materials when unfolded and folded is constant, and the design property is improved. Rise. The first suspension means and the second suspension means are alternately arranged when the first suspension means and the second suspension means are viewed from one to the other in the longitudinal direction of the rail. Means alternating. That is, in addition to the case where there are every other first suspension means and second suspension means on the rail, there are spare suspension means other than the first suspension means and the second suspension means on the rail. May be.

  Further, both the end of the first shielding member and the end of the second shielding member may be suspended from the same suspension means disposed at the end of the rail. According to such a configuration, the first shielding material and the second shielding material can be disposed at both ends of the shielding device, so that the heat insulation performance is improved.

  The first shielding material and the second shielding material may be pleated screens. If a pleat screen is used as the shielding material, an air layer is formed between the front and rear pleat screens like a honeycomb screen, and the heat insulation performance is enhanced. In addition, by connecting the vicinity of the upper end of the crease projecting on the side facing the rail side of each pleat screen to each runner, the front and rear screens can be opened and closed along the rail without interference, and when deployed, front and rear The peaks and valleys of the screens are arranged to coincide with each other, and a predetermined interval is formed between the front and back screens.

  The first shielding material and the second shielding material may be curtains. Even if a curtain is used as the shielding material, the same effect as described above can be obtained. Moreover, the design characteristic peculiar to a curtain is acquired.

  According to the present invention, in a shielding device in which two shielding members are arranged in parallel, the productivity is excellent and the cost can be reduced. Other effects of the present invention will also be described in a mode for carrying out the invention described later.

The position of the valley 130b-2 of the second screen 130-2 substantially corresponds to the position of the first runner 112.

(Spacer code 140)
The spacer code 140 allows the runners 110 to be arranged at equal intervals when the pleat screen 130 is deployed, and the preceding runner 110 pulls the subsequent runner 110 when the pleat screen 130 is deployed. It is. As shown in FIG. 1B, the spacer cord 140 is a cord-like member that extends over almost the entire length of the rail 120, and the runners 110 are connected at equal intervals. When the pleat screen 130 is folded, the spacer cord 140 hangs down between the adjacent runners 110, and when the pleated screen 130 is unfolded, the spacer cord 140 is configured to stretch between the adjacent runners 110.

  The configuration of the shielding device 100 according to the present embodiment has been described above. Next, operation | movement of the shielding apparatus 100 of this embodiment is demonstrated, referring FIG. FIG. 3 is a view for explaining the operation of the shielding device 100, FIG. 3 (a) is a view showing a state when the screen is folded, and FIG. 3 (b) is a part of the screen pulled out.

Further, since an air layer is formed between the first and second screens 130-1 and 130-2, the heat insulating performance is improved. Furthermore, since the front and back first and second screens 130-1 and 130-2 can be arbitrarily selected and combined, the degree of freedom as an interior is improved.

  In addition, since the first runner 112 and the second runner 114 are alternately arranged on the rail 120, the two front and rear first and second screens 130-1 and 130-2 are suspended at a constant interval. For this reason, the state of the wrinkles of the first and second screens 130-1 and 130-2 before and after unfolding and folding is made constant, and the design is improved.

  In addition, since a pleated screen is used as the shielding material, an air layer is formed between the front and back first and second screens 130-1 and 130-2 like a honeycomb screen, so that the heat insulation performance is improved. In addition, the first runner 112 is connected to the first runner 112 in the vicinity of the upper end (the crest 130a-1 and the trough 130b-2) of the fold projecting to the side facing the rail 120 of each of the first and second screens 130-1 and 130-2. By connecting to the second runner 114, the front and rear first and second screens 130-1 and 130-2 can be opened and closed along the rail 120 without interference. At the time of deployment, the peaks and valleys of the first and second screens 130-1 and 130-2 on the front and rear sides are arranged to coincide with each other, and a predetermined interval is formed between the first and second screens 130-1 and 130-2 on the front and rear sides.

For this reason, since the 1st screen 230-1 and the 2nd screen 230-2 can be arrange | positioned at the both ends of the shielding apparatus 200, the heat insulation performance of the shielding apparatus 200 increases.

(Third embodiment)
Next, a shielding apparatus 300 according to the third embodiment will be described mainly with reference to FIG. FIG. 5 is a plan view of the shielding device 300 according to the third embodiment as viewed from above. The present embodiment is different from the first embodiment in that the pleat screen 130 of the first embodiment is a curtain 330, and the other points are the same as in the first embodiment. In the present embodiment, a description will be given centering on differences from the first embodiment. Constituent elements having substantially the same functional configuration are denoted by the same reference numerals, and redundant description is omitted.

  As shown in FIG. 5, the shielding apparatus 300 according to the present embodiment uses a curtain 330 instead of the pleated screen 130 according to the first embodiment. The curtain 330 includes a first screen 330-1 and a second screen 330-2 formed of curtain fabric. The first screen 330-1 corresponds to the first screen 130-1 of the first embodiment and is connected to the first runner 312. The second screen 330-2 corresponds to the second screen 130-2 of the first embodiment and is connected to the second runner 314.

Further, although the spacer cord is a cord-like member extending over almost the entire length of the rail, the present invention is not limited to this example. For example, the spacer cord may be a spacer link that connects adjacent suspension means at a predetermined interval.

  The embodiments and application examples described above can be arbitrarily combined. For example, in the second embodiment, in a state where the second screen 230-2 is unfolded, the valley portion 230b-2 of the pleats at both ends protrudes to the outdoor side from the valley portion 230b-2 of the other portion. However, by shortening the pleat pitches at both ends, the amount by which the valley portions 230b-2 of the pleats at both ends protrude more outdoors than the valley portions 230b-2 of the other portions may be the same. In the third embodiment, the first screen 330-1 and the second screen 330-2 are connected to the first runner 312 and the second runner 314 in the same manner as in the first embodiment. You may connect similarly to 2 embodiment. That is, you may make it connect the both ends of the 2nd screen 330-2 of 3rd Embodiment to the 1st runner 312 of both ends.
