Description

[Detailed description of the invention] (Field of industrial application) This invention is a roll-up windproof tent that is hung from the ceiling and selectively prevents wind from entering by rolling up and unrolling. This relates to the membrane structure of.

(Prior Art) This type of roll-up windproof tent has been widely used in recent years at work sites, cargo handling workplaces, various outdoor event venues, and the like. The tent should be lowered so that work can be carried out in a state that prevents wind from entering the tent, and when putting trucks or rental items inside the tent, the tent should be The membrane body constituting the system is rolled up one after another and stored on the ceiling or the like.

By the way, when this membrane is rolled up, there is no problem if the membrane is folded properly, but in the past, the folding is not done properly. There are various reasons for this, but mainly because this type of roll-up windproof tent is used to prevent wind from entering, the membrane has a relatively large area, and this This is because the membrane itself is made of relatively thick fabric for wind protection or strength, so it will not fold properly in its natural state. Additionally, if some external force is applied to this membrane while it is being rolled up, such as when a wind blows, the membrane will deform in response to this force since it is simply suspended. Even when it is twisted, the membrane cannot be folded properly.

Therefore, a ``curtain opening/closing device'' has been proposed in Japanese Utility Model Application Publication No. 178988/1988, which allows the membrane to always be folded in a fixed direction when the membrane is folded up. However, the "curtain opening/closing device" disclosed in this publication alone cannot complete this type of roll-up windproof tent.

In other words, this type of windproof tent is literally meant to protect against the wind, and the membrane that makes up the tent is subject to the force of the wind. Therefore, it goes without saying that this type of windproof tent must have a structure that prevents the wind from passing through, but when wind force is applied to the membrane, this force causes the membrane to It must not be exposed to such direct wind force that it may be damaged.
In this regard, the "curtain" shown in the above-mentioned publication only has a weight member at the lower end of the curtain fabric, so when the curtain fabric is exposed to strong winds, it will sway and the "curtain" It is considered that the product does not function adequately as a.

(Problems to be solved by the invention) This invention has been made in view of the above-mentioned circumstances, and the problem to be solved by the invention is that even if the structure is simple, The object of the present invention is to propose a membrane structure that can be easily and neatly folded, and that can also make the unfolded membrane a flexible structure and protect it from the force of the wind.

(Means for solving the problem) In order to solve the above problems, the method taken by the present invention is to fold the membrane suspended from the ceiling by winding up the wire connected to the lower end of the membrane. In the windproof tent, the membrane body is unfolded by unwinding the wire to form a wind shielding surface, and the horizontal rods are arranged on one side of the membrane body at a predetermined interval from each other. A guide ring for guiding the wire is attached to the horizontal rod, a weight rod is attached parallel to the horizontal rod to the other side of the membrane that forms the fold, and a weight rod is attached to the lower end of the membrane. A weight rod having a plurality of guide members fixed to its lower side is connected to the weight rod, and a support rope is attached to the guide member through a hook that is selectively locked to a locking device located on the ground side. It has a membrane structure.

(Operation of the invention) Next, the operation of the membrane structure according to the invention configured as described above will be explained.

First, this membrane structure exerts its effect only when the membrane body 12 of the windproof tent 10 is folded, and its effect is exerted on the lower side of the membrane body 12 as shown in FIG. This is done sequentially from In addition, the membrane body 12 is lowered by its own weight and the weight of the horizontal rods 11 and weight rods 18 attached to it, and the membrane body 12 is lowered by winding up the wire 14 connected to its lower end one after another. This is because the body 12 is pulled in from below.

In the middle of winding up the membrane 12, as described above, the part of the membrane 12 to which the various rods 11 are fixed is pulled toward the wire 14, while the fold 17 of the membrane 12 is folded under the weight of the weight rod 18 attached here. Since the membrane body 12 is pulled downward from the front side by the membrane body 12, the folds 17 of the membrane body 12 and the portions where the transverse rods 11 are fixed are alternately located inside and outside. By this,
The membrane body 12 is folded in an orderly manner.

In addition, in the windproof tent 10 as described above, each hook 25 supported by each support rope 24 is locked to the horizontal rod 26a of each locking device 26 located below. It will be completed. As a result, the lower end of the membrane body 12 is connected to the base 27, but this connection state is not fixed at all, but has a certain degree of freedom.

That is, the support rope 24 is slightly longer than the weight rod 22, and each hook 25 can slide in the lateral direction with respect to the support rope 24, so that wind pressure is not applied to the membrane 12. In this case, the lower end of the membrane body 12 can move somewhat relative to the base 27. As a result, when the force of the wind applied to the windproof tent 10 is weak, the membrane body 12
hangs vertically downward due to the weight of the windproof tent 10 itself and the weight rods 22; on the other hand, if the wind force is stronger than this, the membrane 12 will fall within the allowable range of the support ropes 24 and hooks 25. The membrane body 12 is supported by each of the locking tools 26 of the base 27 while appropriately escaping the wind that the membrane body 12 receives.

Therefore, the expanded membrane body 12 connects the connecting rods 21,
Since it is indirectly supported by each hook 25 of the base 27 via the support rope 24, the guide member 23, and the hook 25, even if this membrane body 12 receives wind pressure, the force due to this is directly applied to the membrane body 12. Never. Furthermore, since each support rope 24 has a predetermined degree of freedom with respect to the guide member 23, and the hook 25 has a predetermined degree of freedom with respect to the support rope 24, even if the membrane body 12 swings due to wind pressure, The force caused by the shaking is not applied directly to the membrane body 12. In other words, no matter what the situation is, no force is directly applied to the membrane body 12;
Therefore, the membrane body 12 will not be damaged.

(Example of the invention) Next, the membrane structure according to the invention will be described in detail according to the example shown in the drawings.

FIG. 1 shows a partially cutaway rear view of a windproof tent 10 in an unfolded state that employs a membrane structure according to the present invention. In this windproof tent 10, a plurality of horizontal rods 11 are arranged parallel to each other, and a membrane body 12 is stretched over the front surface of each horizontal rod 11. Above this membrane body 12, a support stand 13 is fixed in a horizontal state via a bracket 13a fixed to the ceiling (not shown), and on this support stand 13 are mounted a plurality of supports driven by a drive motor M. A winder 15 for winding up the wire 14 is arranged. Further, each wire 14 is sequentially inserted through each guide ring 16 attached to the back side of each horizontal rod 11, and its lower end is fixed to the lowermost end side of the membrane body 12. In addition, the code|symbol 14a in the figure has shown the rope for fall prevention.

As a result, in the windproof tent 10,
The film body 12 completely unwinds each wire 14 to be in the unfolded state as shown in FIG. At this time, the entire membrane body 12 is folded and stored together on the support stand 13 side.

Further, in the membrane body 12 of the windproof tent 10, a fold line 17 is formed approximately in the middle of each horizontal rod 11, and a weight rod 18 having a predetermined weight is placed slightly below the surface side of the fold line 17. are fixed so as to be parallel to each horizontal rod 11. Actual fixation is achieved by forming a part of the membrane 12 into a bag shape and inserting the weight rod 18 into the bag. By doing this, when the membrane body 12 located between the horizontal bars 11 is wound up by each wire 14, it is fixed via each horizontal bar 11 located on the back side. The part of the membrane 12 is pulled toward the wire 14, and on the other hand, the fold 17 of the membrane 12 is pulled away from the front side of the membrane 12 by the weight of the weight rod 18 attached here. It is being pulled downward.

Further, on the lower side of the windproof tent 10, the horizontal rod 11 located at the lowest end is used as a connecting rod 21. The connecting rod 21 integrally supports the lower end of the membrane 12 by winding a rope that is continuously inserted through the lower end of the membrane 12 around the connecting rod 21. Further, a weight rod 22 is horizontally connected to the connecting rod 21 via a plurality of connecting arms 21a. By increasing the weight of the weight rod 22, it pulls the deployed membrane 12 downward, and even if wind pressure is applied to the membrane 12, the membrane 12 does not easily sway. It is intended to do so.

A plurality of guide members 23 are fixed to the lower side of the weight rod 22 in the lateral direction of the weight rod 22, and a support rope 24 is attached to each of these guide members 23 with a degree of slack as shown in FIG. are connected. That is, especially in this embodiment, the support rope 24 has a length slightly longer than the weight rod 22, and is slidably inserted into each guide member 23 located between the weight rods 22. are fixed to each guide member 23 located at the end of the weight rod 22.

Therefore, in the embodiment shown in FIG.
A hook 25 (described later) is attached to the end of the weight rod 22.
Although an example is shown in which the hook 25 is inserted through the weight rod 22, this hook 25 can also be inserted and supported at the middle part of the weight rod 22, so that the hook 25 can be supported at any position on the weight rod 22. It is possible. That is, each guide member 23 has a partially annular shape, and the support rope 24 can be connected to it or supported in a slidable manner as desired. Of course, the support rope 24 that supports this guide member 23
As shown in FIG. 1, a pair of guide members 23 are fixed only at the ends of the weight rods 22.
It may also be implemented by connecting the support rope 24 to the support rope 24.

Further, a hook 25 is inserted through the support rope 24, so that the hook 2 is slidably supported with respect to the support rope 24. This hook 25 has a locking tool 26 located below it.
The locking device 26 can be selectively locked to the locking tool 26, and locking to the locking tool 26 is performed manually. The locking tool 26 is buried in a base 27 located directly below the windproof tent 10 so that its upper surface does not protrude from the base 27, and the hook 25 is
It is equipped with a horizontal rod 26a for locking.

(Effects of the invention) According to the membrane structure according to the present invention configured as described above, the part of the membrane 12 to which each horizontal rod 11 is fixed is drawn toward the wire 14, while the fold 1 of the membrane 12
7 is pulled downward from the front side of the membrane body 12 by the weight of the weight rod 18 attached here.
By alternately positioning the folds 17 of the membrane 12 and the portions to which the horizontal bars 11 are fixed inside and outside, the membrane 12 can be neatly folded for each horizontal bar 11 and fold 17. In addition, as described above, each horizontal rod 1
The part of the membrane 12 where the membrane 1 is fixed is always pulled toward the wire 14 during the folding process, while the fold 17 of the membrane 12 is pulled downward from the front side of the membrane 12 by the weight of the weight rod 18 attached here. Since it is pulled, even if an external force is applied to the membrane 12 by wind or the like, the membrane 12 can be reliably folded without disrupting the order.

Further, when the membrane body 12 is unfolded, the membrane body 12 can be unfolded in an orderly manner from above the folded state due to the weight of the weight rod 18 without being disturbed. In this case, since not only the weight of the weight rod 18 but also the weight of the weight rod 22 is added, the unfolding operation can be performed more smoothly without causing disturbance to the membrane body 12.

Further, according to this membrane structure, the unfolded membrane 12 is supported by the support rope 24 attached to its lower end.
Since each hook 25 inserted through the membrane body 1 is locked to a locking tool 26 on the ground side, the membrane body 1 exposed to the wind is
2 does not sway significantly, and the windproof effect can be reliably achieved. Since each hook 25 is movable with respect to the support rope 24, the membrane 12 swings within a predetermined range when the membrane 12 receives a large wind force. It can be protected without being damaged.
