Description

  The present invention relates to a curtain, and more particularly to a curtain used mainly for business purposes.

Curtains are often used as simple doors that can be opened and closed in large warehouses, garages, factories, and other buildings. For example, a curtain is used as an openable / closable partition for partitioning the room from the outside, and as an openable / closable partition for partitioning the room into a plurality.
Such a curtain is generally a large-scale one made using a film material or the like used for a tent. The vertical and horizontal lengths usually exceed 10 m depending on the case.

The required dimensions of the curtain vary depending on the site where it is used. The dimensions in this case are a vertical dimension and a horizontal dimension.
The curtain is generally constituted by connecting a plurality of curtain bodies, which are rectangular film materials cut out from a long film material roll, in the width direction. Since it is easy to adjust how many curtain bodies are connected in the width direction, adjustment of the horizontal dimension of the curtain is simple.

On the other hand, it is difficult to adjust the vertical dimension of the curtain. The vertical dimension of the curtain is adjusted by placing the lower end of the curtain on the ground (in this application, the term “ground” is used not only on the outdoor ground surface (regardless of whether or not pavement or the like is leveled)), but also on the indoor ground surface. Or used to mean including floors.) It is performed for the purpose of adjusting to the last minute. If there is a gap between the bottom edge of the curtain and the ground, the wind will blow into it, causing damage to the structure with the curtain (this is often the case if the structure is outdoors) May occur). In addition, in a state where the lower end of the curtain is dragged on the ground, the curtain is quickly damaged. In addition to the above-mentioned problems, it is important to match the lower end of the curtain to the edge of the ground from the viewpoint of appearance.
Adjustment of the length of the curtain in the vertical direction can be realized, for example, by adjusting the length of each curtain body connected in the width direction in the vertical direction. However, it is technically feasible but difficult to adopt in practice. From the viewpoint of the curtain supplier, it is preferable to standardize the curtain length in terms of cost competitiveness, so it should be custom-made to change the length of the curtain body as necessary. Technology is difficult for manufacturers to make curtains. In the curtain technology field, commoditization is progressing remarkably, so maintaining price competitiveness is an extremely important issue for manufacturers.

Also, the curtain may be reused multiple times. For example, when recycling is performed, the curtain is reused. In addition, the curtain is not only sold out, but may be rented. However, even when the curtain is rented, the curtain is reused.
In such a case, the required vertical dimension of the curtain differs depending on the site where the curtain is used. In such a case, the importance of the technique for adjusting the vertical dimension of the curtain becomes more and more important.

As described above, adjustment of the horizontal dimension of the curtain is easy, but adjustment of the vertical dimension of the curtain is not easy.
From such a point of view, there are some manufacturers that provide only curtains with vertical dimensions that have been standardized in advance. However, there are, of course, consumers who demand curtains having a preferred vertical dimension, and providing only standardized vertical curtains cannot meet the demands of such consumers.
In view of such a point, the present applicant has proposed a new curtain in Japanese Patent Application Laid-Open No. 2015-207. Such a curtain follows a basic structure of a curtain or a conventional manufacturing method in which a plurality of standard longitudinal curtain bodies are connected in the width direction. The lower curtain body that is movable in the vertical direction is connected to each curtain body.

The technology disclosed in the above-mentioned patent application can adjust the vertical dimension of each curtain body by moving the lower curtain body connected to each curtain body up and down, thereby adjusting the vertical dimension of the curtain. It is possible to do that. In addition, this technology follows the basic structure of a curtain or the conventional manufacturing method of connecting a plurality of standard vertical curtain bodies in the width direction. Can be suppressed.
In addition, this curtain can adjust the length of the lower curtain body attached to each curtain body to a different height, thereby changing the curtain length depending on the position in the width direction. There is also an advantage that it can be applied to a curtain to be arranged.
However, such a curtain requires that a lower curtain body be connected under each curtain body, and such a connection is made by connecting the lower curtain body connected to each curtain body to the curtain body to which the curtain body is connected. On the other hand, since it is necessary to be able to move in the vertical direction, a new part for making such a connection is required, and the effect of cost reduction may be limited.
In addition, some customers may wish to further reduce the cost instead of the function of changing the curtain length depending on the position in the width direction. Therefore, the curtain as described above may be over-spec. is there.

  It is an object of the present invention to provide a technique for matching the lower end of the curtain to the edge of the ground, which can be used at low cost and can be used for reuse of the curtain.

In order to solve the above-mentioned problems, the present inventor proposes the following curtain structure set. The curtain structure set is a set of parts for making a curtain structure. When the curtain structure set is assembled, it becomes a curtain structure.
The present invention is a rod-like body that is used by standing vertically with respect to the ground at a predetermined interval, and is used by being two rod-like bodies that are both rod-like bodies and extending substantially horizontally between the two pillars. A curtain structure set having a curtain rail and a curtain made of a film material having a rectangular shape and attached to the curtain rail so that the upper side of the curtain rail is movable along the curtain rail.
And the length of the two pillars in this curtain structure set is longer than the vertical dimension of the curtain, and the curtain rail is in a specific range that is a predetermined range of the two pillars, The height from the ground is variable, and both ends can be fixed to the two pillars.
The specific range in the present invention is defined as follows.
The distance from the lower end of the two columns to the upper end of the specific range in the two columns is equal to or greater than the length of the vertical dimension of the curtain.
In addition, an anchor that supports the column in a state of floating from the ground can be attached to the lower ends of the two columns as needed, and the specific range of the two columns is within the specific range. The distance from the lower ends of the two pillars to the lower end is a distance obtained by combining the distance and the maximum distance at which the lower end of the pillar is expected to float from the ground by the anchor. The length is the same as or smaller than the length of the vertical dimension.

The curtain structure body according to the curtain structure set does not change the vertical dimension of the curtain by using another film material such as the lower curtain body described in the prior art. Further, the vertical dimension of the curtain in this curtain structure set is not changed by appropriately selecting the length in the vertical direction, even if the curtain body described in the prior art is included therein. Instead, in the curtain structure in this curtain structure set, the lower end of the curtain can be adjusted to the ground by moving up and down the curtain rail itself hanging the curtain.
By the way, in the curtain structure, if the two pillars are always placed on the ground as they are, the curtain is positioned with a certain distance from the lower end of the pillar according to the vertical dimension of the curtain. If the rail can be attached to the pillar, the lower end of the curtain whose vertical dimension is standardized and whose upper side is attached to the curtain rail can be adjusted to the level of the ground.
However, things are not so easy. This is because an anchor may be disposed at the foot of a column in a site where a curtain structure is used. The anchor mainly plays the role of a weight to increase the stability of the pillar used in the state where it stands upright on the ground, but the lower end of the pillar is floating from the ground when attached to the anchor. . Therefore, if the fixing position of the curtain rail with respect to the column is not variable, a gap is left between the lower end of the curtain and the ground when the anchor is used. In addition, anchors are not always used, and there are various types of anchors, so the distance from the lower end of the pillar to the ground when using them varies. If the vertical dimension of the curtain can be corrected afterwards, such as by using other film materials such as the lower curtain body, or at the site where the curtain structure is laid, the above problems originating from the anchor However, in the case of the curtain structure set of the present application, some device is required to avoid the problem. The idea is that the curtain rail can be attached to the column by changing the vertical position relative to the column within a specific range of the column.
As described above, the distance from the lower ends of the two columns to the upper end of the specific range of the columns is equal to or greater than the length of the vertical dimension of the curtain. In addition, the distance from the lower end of the column to the lower end of the specific range of the column is the distance between the distance and the maximum distance at which the lower end of the column is expected to float from the ground by the anchor. The length is the same as or smaller than the length of the vertical dimension.
When the pillar is arranged on the ground without an anchor, the curtain rail may be attached to the pillar at a position separated from the lower end of the pillar by the vertical dimension of the curtain in order to align the lower end of the curtain with the ground margin. Since the distance from the lower ends of the two columns to the upper end of the specific range in the column is equal to or greater than the length of the vertical dimension of the curtain, according to the curtain structure set according to the present invention, the curtain at the above position It is possible to attach the rail to the pillar. In addition, when the pillar is upright with respect to the ground via the anchor, the bottom edge of the curtain is lifted from the ground by the anchor from the bottom of the pillar, from the vertical dimension of the curtain, in order to align the bottom edge of the curtain with the bottom of the ground. The curtain rail may be attached to the pillar at a position separated by the length reduced in height. The distance from the lower end of the column to the lower end of the specific range of the column is the distance between the distance and the maximum distance at which the lower end of the column is expected to be lifted off the ground by the anchor. Therefore, according to the curtain structure set according to the present invention, no matter what the anchor is (in other words, the lower end of the pillar is grounded by the anchor). It is possible to attach the curtain rail to the column in the above-mentioned position, no matter how much it is lifted from.
That is, the curtain structure made by the curtain structure set of the present invention can match the lower end of the curtain to the edge of the ground. In addition, since such a curtain structure can standardize the vertical dimension of the curtain, it is difficult to increase the cost. Further, when an anchor is not used, it is possible to cope with the case where it is used, and even when various anchors are used, it is possible to reuse the portion excluding the anchor.

The specific range in the two pillars is the range described above.
However, the specific range may extend to the lower ends of the two pillars. Further, the specific range may extend to the upper ends of the two pillars.
The installation position of the curtain rail in the specific range may be a continuous floor or a continuous floor, but may be at predetermined intervals regardless of whether it is constant or not. In general, if the height position of the curtain rail can be adjusted in steps of several centimeters, it is sufficient for practical use.
Any method of fixing the rail to the curtain rail may be used, but if the curtain structure set is reused, the fixing is not irreversible such as welding, but can be released by screwing or the like. It is preferable.

Although not limited to this, the curtain structure set includes a land beam that is a rod-like body, which is passed substantially horizontally between the two pillars, and the position where the land beam is passed is The lower end of the curtain may be positioned immediately above the height of the curtain rail when the lower end of the curtain is aligned with the lower end of the column.
As described above, the curtain structure made by the curtain structure set has a curtain rail. The rigidity of the curtain structure can be increased by providing a reinforcing structure such as a truss structure including a truss beam above the curtain rail, for example, between the curtain rail and the roof aggregate located above the curtain rail. . However, as described above, since the curtain rail in the present invention moves in the vertical direction, it is difficult to provide a reinforcing structure between the curtain rail and the roof aggregate.
On the other hand, if there is a land beam that does not move up and down with respect to the two pillars on the curtain rail, a reinforcing structure can be provided between the land beam and the roof aggregate. In addition, the land beam is present at the position of the curtain rail when the curtain bottom is aligned with the bottom of the pillar, that is, the position directly above the highest height when the curtain rail is attached to the pillar. If it exists, the height of the curtain structure made by the curtain structure set can be made compact.
Although not limited to this, the curtain structure set may include a covering material that is a film material that covers the space above the land beam between the two pillars in use.
As a result, the portion above the land beam in the space between the two pillars of the curtain structure made by the curtain structure set is filled with the covering material. The space before and after the pillar of the book can be partitioned.
The above-described covering material covers not only the portion above the land beam in the space between the two pillars of the curtain structure but also the portion further above the two pillars or other portions. It may be anything. For example, the covering is between the two pillars in use, in addition to the space above the land beam, between the two pillars in use, and below the land beam The film material may cover at least the height range corresponding to the maximum distance where the lower end of the pillar is expected to be lifted from the ground by the anchor. As described above, when the anchor is used, the curtain rail is attached to the column at a position closer to the lower end of the column than when the anchor is not used. In that case, if the curtain structure set includes a land beam, a gap is generated between the curtain rail whose mounting position moves downward and the land beam. If the covering material is as described above, the covering material can be used to cover the space between the curtain rail and the land beam generated when the anchor is used. When the covering material is such, between the two pillars of the covering material in use and below the portion covering the space above the land beam, You may provide the means fixed in the wound state. According to this, the covering material below the land beam can be unwound and used only when necessary.

Although not limited to this, the curtain structure set of the present application includes anchors that are attached to the lower ends of the two pillars and support the pillars in a state of floating from the ground. It may be provided with a lower membrane material which is a membrane material between the pillars, on the curtain rail and covering the space below the land beam.
If the anchor is included in the curtain structure set, the size and shape of the space created between the curtain rail and the land beam when the anchor is used can be understood without making the curtain structure. ing. If the space is included in the curtain structure set as a lower membrane material, the lower membrane material can be used to cover the space between the curtain rail and the land beam.

As described above, the curtain in the present application is a rectangular film material.
Although not limited to this, the curtain in the present application may be formed by connecting a plurality of curtain bodies, which are vertically long rectangular film members, in the width direction. That is, the curtain included in the curtain structure set according to the present invention can be manufactured by the manufacturing method described in the related art.
In this case, a rod-shaped body for increasing the longitudinal rigidity of the curtain body may be disposed between the adjacent curtain bodies. As a result, the lower end of the curtain can be prevented from rising.
Although not limited to this, the horizontal dimension of the curtain may be substantially coincident with the interval between the two pillars.
Further, the curtain may be formed by stretching a film material in a frame having a rectangular shape. In this case, the horizontal width of the frame is shorter than the interval between the two pillars, for example, 1/2 or less. By doing so, the frame can be used as if it were a door. There may be a plurality of frames over which the film material is stretched. In that case, the total width of the plurality of frames is shorter than the interval between the two pillars, and can be, for example, ½ or less.

The inventor of the present application also proposes a curtain structure made using the above-described curtain structure set as an aspect of the present invention. Even with such a curtain structure, it is possible to obtain the same effects as those obtained by the curtain structure set.
An example of the curtain structure is a curtain structure configured by using any one of the curtain structure sets described above, and the curtain has its ground so that its lower side is substantially along the ground. It is the curtain structure attached to the said curtain rail adjusted height from.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an overview of a tent constructed using various parts including the curtain structure set in this embodiment.
A tent is roughly composed of a membrane material and an aggregate that supports it. The tent includes a wall 100 and a roof 200. Three of the walls 100 are literally walls that cannot be opened, and one of the walls 100 is a curtain structure 100A that can open a curtain 300 described later. In FIG. 1, the front surface of the tent is the curtain structure 100 </ b> A, and the components constituting the curtain structure set are the curtain structure set.

The tent includes a pillar 110 as an aggregate. The tent is rectangular in plan view, and is provided with pillars 110 at four corners when viewed in plan. But the pillar 110 may be provided in the place other than that of a tent. The pillar 110 is built substantially perpendicular to the ground.
The column 110 forms a part of the above-described aggregate, and is required to have enough strength to support the load of the membrane material. As long as this is possible, the pillar 110 may be a rod-shaped body of a basket. The pillar 110 is made of metal or wood.
The portion of the wall 100 between the tent pillars 110 is covered with a wall film material 101 which is a film material. The method for fixing the column 110 and the wall film material 101 may be in accordance with a known or well-known technique.
A roof aggregate 210 that outlines the roof 200 is provided on the portion of the roof 200 above the tent pillar 110. The roof aggregate 210 may be a well-known or publicly known material, but can be formed of a metal square pipe similar to the pillar 110, for example.
A portion surrounded by the roof aggregate 210 of the roof 200 is covered with a roof membrane material 201 which is a membrane material. The method for fixing the roof aggregate 210 and the roof membrane material 201 may be in accordance with known or well-known techniques.

But the pillar 110 in the part located in the right and left of the curtain structure 100A is comprised as follows.
Although not restricted to this, the pillar 110 in the part located in the left and right of the curtain structure 100A is made of metal and is constituted by a square pipe. The cross-sectional shape of the pillar 110 that is a square pipe is not limited to this, but is a rectangle. In this embodiment, the cross-sectional shape is not limited to this, but is a square.
The length of the pillar 110 is longer than the vertical dimension of the curtain 300. Since the standardized vertical dimension of the curtain 300 in this embodiment is 400 cm, the length of the pillar 110 is higher than that. The length of the column 110 needs to be longer than the vertical dimension of the curtain 300 + the maximum height of an anchor to be described later. In this embodiment, although not limited to this, the length of the column 110 is set to 480 cm in consideration of a further allowance while considering that the planned maximum height of the anchor is 60 cm.
Although not restricted to this, the 1st fixed board 111 which is a metal plate-like body is provided in the predetermined height of those pillars 110. FIG. The first fixing plate 111 is for fixing a later-described land beam to the column 110.
The first fixing plate 111 is substantially rectangular, and is fixed to the column 110 by an appropriate fixing method such as screwing or welding. The first fixing plate 111 is fixed to the front and rear surfaces of the column 110 in FIG.
As shown in FIG. 2, the lateral length of the first fixing plate 111 is larger than the lateral width of the front and rear surfaces of the pillar 110, and the first fixing plate 111 is fixed to the pillar 110 in the state of being fixed to the first The inner side of the plate 111 protrudes toward the other pillar 110 side. The heights of the four first fixing plates 111 attached to the front and rear of the two pillars 110 located at the left and right portions of the curtain structure 100A are the same.
A portion of the first fixing plate 111 that protrudes from the column 110 to which the first fixing plate 111 is fixed to the other column 110 is provided with a hole (not shown).
The land beam 120 is fixed to the pillar 110 at both ends by using such a first fixing plate 111. The land beam 120 is a rod-like body passed between the pillars 110. The length of the land beam 120 corresponds to the distance between the two columns 110 provided with the first fixing plate 111. Although not restricted to this, the land beam 120 of this embodiment is metal, and is comprised with the square pipe. The cross-sectional shape of the land beam 120, which is a square pipe, is not limited to this, but is a rectangle. In this embodiment, the cross-sectional shape is a square, although not limited thereto. In addition, a hole (not shown) is drilled at a corresponding position on two opposing surfaces in the vicinity of both ends of the land beam 120.
The land beam 120 is first fixed in a state where both ends thereof are respectively inserted between the two first fixing plates 111 provided before and after the two pillars 110 provided with the first fixing plate 111. By screwing nuts (not shown) into the tips of the bolts 121 through which the holes provided at the ends of the plate 111 and the land beam 120 are collectively penetrated, both ends thereof are fixed to the pillars 110. .
The land beam 120 only needs to be fixed substantially horizontally to the pillars 110 located on the left and right sides of the curtain structure 100A. Of course, the method is not limited to that described above.
Although not limited to this, in this embodiment, a truss structure formed by assembling the truss beams 220 is provided between the land beams 120 and the roof aggregate 210. Due to the presence of the truss structure, the rigidity of the curtain structure 100A of the tent is improved.

  The space surrounded by the pillar 110 on the land beam 120 is not limited to this, but is covered with a covering material 500 that is the same film material as other film materials. The covering material 500 is arranged on the front side of the truss beam 220 in this embodiment. The configuration of the covering material 500 will be described in detail later.

A curtain rail 130 is attached substantially horizontally below the land beams 120 of the two pillars 110 in the left and right portions of the curtain structure 100A.
The curtain rail 130 suspends a curtain to be described later from above, and guides the curtain in the horizontal direction. The curtain rail 130 is a rod-shaped body. In this embodiment, the curtain rail 130 is made of metal and is constituted by a square pipe. The cross-sectional shape of the curtain rail 130, which is a square pipe, is not limited to this, but is a rectangle. In this embodiment, the cross-sectional shape is not limited to this, but is a square. In addition, a hole (not shown) is formed at a corresponding position on the two opposing surfaces in the vicinity of both ends of the curtain rail 130.
The curtain rail 130 can be attached to both ends of the curtain rail 130 so that the position of the curtain rail 130 in the vertical direction can be changed. A mechanism for allowing the curtain rail 130 to be attached to the pillar 110 with its height position being variable is, for example, as follows.

As shown in FIG. 2 (A), holes 112 are formed in front and rear of the pillars 110 in the left and right portions of the curtain structure 100A. A plurality of holes 112 are formed in the height direction of the pillar 110. The holes 112 before and after the pillar 110 correspond to the positions, shapes, and sizes thereof. Further, the holes 112 provided in the two pillars 110 are all in the same position, and have the same shape and size. Although not limited to this, the hole 112 is circular. Further, although not limited to this, the distances between the holes 112 adjacent to each other in the vertical direction of each hole 112 are all equal.
The curtain rail 130 is fixed to the pillar 110 at both ends using the holes 112 described above. In this embodiment, for this purpose, a T-shaped second fixing plate 140 is used. The second fixing plate 140 includes a rectangular base plate 141 and a rectangular protruding plate 142 protruding from the middle of the base plate 141. Although not shown in the drawings, both ends of the base plate 141 are formed with circular holes in this embodiment. The distance between the two holes provided at both ends of the base plate 141 is the same as the distance between the adjacent holes in the upper and lower sides of the multiple holes 112 provided in the column 110. In addition, although not shown in the drawings, the protruding plate 142 is formed with a circular hole in this embodiment.
The curtain rail 130 is attached to the pillar 110 at both ends via the second fixing plate 140. One second fixing plate 140 is attached before and after each pillar 110. The height from the ground of the 2nd fixing plate 140 attached to each pillar 110 is made to correspond. For fixing the second fixing plate 140 to the pillar 110, a hole 112 provided in the pillar 110 is used. A thread groove is cut in the inner peripheral surface of the hole 112. By screwing the front end of the second fixing plate 140 along the front side of the column 110 from the front side of the second fixing plate 140 into the hole 112, the bolt is penetrated from the front side of the base plate 141. The second fixing plate 140 can be attached to the front side of the column 110. Similarly, the hole formed at the top and bottom of the base plate 141 of the second fixing plate 140 along the rear side of the column 110 and the tip of the bolt 144 penetrating from the rear side of the second fixing plate 140 into the hole 112. The second fixing plate 140 can be attached to the rear side of the pillar 110 by screwing.
When one second fixing plate 140 is attached to the pillar 110, two holes adjacent in the vertical direction among the holes 112 provided in the pillar 110 are used. By selecting which two holes 112 are used to fix the second fixing plate 140 to the column 110, it is possible to change at which height of the column 110 the second fixing plate 140 is attached. However, the height of the four second fixing plates 140 attached to the two pillars 110 from the ground is the same in this embodiment.
The curtain rail 130 is inserted in both ends between the protruding plates 142 of the two second fixing plates 140 provided in front of and behind the two pillars 110 provided with the second fixing plate 140, respectively. The nuts (not shown) are screwed onto the front ends of the bolts 143 through which the holes provided at the end portions of the front and rear two projecting plates 142 and the curtain rail 130 are passed, so that both ends thereof are connected to the pillars 110. It becomes a fixed state. In this manner, the curtain rail 130 can be attached to the two pillars 110 at both ends while being substantially horizontal and with the height position with respect to the two pillars 110 adjusted.
Note that the hole 112 described above is not necessarily provided directly to the pillar 110. For example, the auxiliary material 110X having a substantially U-shaped cross section as shown in the front view of FIG. 2B and the horizontal sectional view of FIG. 2C is welded to the surfaces of the two columns 110 facing each other. It is also possible to adopt a configuration in which the hole 112 is provided in the auxiliary agent 110X by fixing by the method. By adopting such a configuration, it is not necessary to make a hole 112 in the pillar 110, so that the strength of the pillar 110 is not reduced.

When the second fixing plate 140 is attached to the pillar 110 using the two holes 112 from the top among the many holes 112 provided in the pillar 110, the curtain rail attached to the second fixing plate 140 130 is positioned directly below the land beam 120.
When the second fixing plate 140 is attached to the pillar 110 using the two lower holes 112, there is a gap between the curtain rail 130 attached to the second fixing plate 140 and the land beam 120. Has come to occur.
The holes 112 provided in the pillar 110 may be provided at equal intervals up to the lower end of the pillar 110, but this need not be the case. This point will be described later.
The holes 112 provided in the pillar 110 may be provided up to the upper side of the first fixed plate 111, but if the tent has the land beam 120, they are practically not used. Of course, in the case where the hole 112 is provided only in a certain range of the pillar 110, the pillar 110 will often have to be manufactured as a dedicated product. It may be on the market. Of course, it is possible to use the column 110 in which the hole 112 is provided over the entire length as the column 110 of this embodiment because the use of such a commercially available column 110 is advantageous in terms of cost. .

A curtain 300 is suspended under the curtain rail 130. The curtain 300 is made of a film material. Although there is no restriction | limiting in particular in the film | membrane material which comprises the curtain 300, The general film | membrane material for tents can be used. In addition, although the film material is used for the tent of this embodiment as described above, the film material used for the wall 100 or the roof 200 of the tent and the film material used for the curtain 300 may be the same. It is not necessary.
The curtain 300 is rectangular. The vertical dimension which is the length of the curtain 300 in the vertical direction is standardized. The curtain 300 is configured by connecting a plurality of rectangular curtain bodies 310 that are cut out from a long roll of film material and extend in the vertical direction in the width direction. The vertical dimension of each curtain body 310 is the above-described standardized dimension, and the vertical dimension of each curtain body 310 is constant depending on the width of the original roll.
Although the horizontal dimension of the curtain 300 is not limited to this, it substantially corresponds to the interval between the two pillars 110 in the left and right portions of the curtain structure 100A. In addition, the vertical dimension of the curtain 300 is not limited to this, but by using the two holes 112 from the top among the many holes 112 provided in the pillar 110, the curtain 300 is directly below the land beam 120. The lower end of the curtain 300 suspended from the curtain rail 130 that has been positioned so as to be positioned is adjusted so as to be positioned at the very bottom of the ground. However, since the vertical dimension of the curtain 300 is standardized, it should be said that such adjustment is performed on the pillar 110 and the curtain rail 130 rather than on the curtain 300. Let's go.
A rod-shaped body 320 is fixed to the edges of the curtain bodies 310 adjacent to each other. The configuration of the rod-shaped body 320 and the method of fixing the rod-shaped body 320 to the curtain body 310 may be in accordance with known or well-known techniques. The rod-shaped body 320 is for increasing the vertical rigidity of the curtain 300. The rod-shaped body 320 can be formed in a pipe shape, for example, so that the weight of the curtain 300 can be reduced.
A large number of suspension members 133 are attached to the curtain rail 130. The suspension member 133 is attached to the curtain rail 130 so as to be movable in the length direction of the curtain rail 130 and has a function of hanging the curtain 300. Since the suspension member 133 is known or well known, a known or well-known configuration may be employed.
In this embodiment, the suspension member 133 is an annular body whose cross section is made slightly larger than the curtain rail 130, and penetrates the vicinity of the upper end of the curtain body 310. The suspension member 133 is penetrated by the curtain rail 130 and is guided along the curtain rail 130 so as to be movable along the curtain rail 130. Although not limited to this, in this embodiment, two suspension members 133 are attached to each curtain body 310. The hanging member 133 may be connected not to the vicinity of the upper end of the curtain body 310 but to the upper end of the rod-shaped body 320.

  In the tent described above, no anchor is used. In such a tent, by appropriately positioning the height of the curtain rail 130 with respect to the pillar 110, it is possible to make the lower end or the lower side of the curtain 300 follow the margin of the ground.

Next, the case where an anchor is arranged under the pillar 110 in the tent described above will be described.
The anchor 400 placed under the pillar 110 is, for example, H steel as shown in FIG. The anchor 400 made of H steel extends in the depth direction of FIG.
The column 110 is fixed to the upper surface of the anchor 400. For example, a known or well-known clamp 410 is fixed at an appropriate position on the upper surface of the anchor 400. By tightening the lower end of the pillar 110 inserted into the clamp 410, the lower end of each pillar 110 is fixed to the anchor 400.
All of the tent pillars 110 are placed on the anchor 400, including the two pillars 110 in the left and right portions of the curtain structure 100A. As a result, the entire tent is raised by the height of the anchor 400 as compared with the tent shown in FIG. Moreover, since there are various anchors 400, the height at which the tent is raised by the anchor 400 varies depending on the case.

As described above, the anchor 400 extends in the depth direction of FIG. 3, and its length extends to the full depth of the tent in FIG. 4. In addition, an anchor 400 extending left and right in FIG. 4 is also arranged below the wall 100 on the back side of the tent. Thereby, the lower part of the tent is in a state surrounded by the anchor 400 except for the curtain structure 100A. That is, even if the anchor 400 is disposed, there is no gap under the wall 100 except for the curtain structure 100A.
It is not always necessary to fill the gap below the wall 100 with the anchor 400. It is easy to close the gap using an appropriate film material or plate.
In the tent of this embodiment, the gap below the curtain structure 100A is closed as will be described later by a device applied to the curtain structure 100A. However, such a device is necessary in the curtain structure 100A. This is because the curtain 300 is a movable member. Therefore, the gap below the wall 100 having no movable member may be appropriately closed.

  FIG. 4 is a front view of the tent curtain structure 100A in a state where the anchor 400 is entirely raised. Since the tent is not laid in this way, this is only a reference diagram. However, if the tent is laid using the anchor 400 without any contrivance, in this way, under the curtain structure 100A, in other words, A gap corresponding to the height of the anchor 400 is generated under the curtain 300.

In the tent of this embodiment, the above-described gap generated under the curtain 300 when the anchor 400 is used is eliminated as follows. Of course, the tent shown in FIG. 5 described below need not be made after the tent shown in FIG. 4 is made once.
As described above, the pillar 110 has a large number of holes 112. When the second fixing plate 140 is attached to the pillar 110 using the two holes 112 from the top of the holes 112, the curtain rail 130 is located directly below the land beam 120 as shown in FIG. Located in.
On the other hand, among the holes 112 bored in the column 110, the hole 112 positioned below the uppermost hole 112 by a height corresponding to the height of the anchor 400 and the hole 112 directly below the hole 112 are used. When the second fixing plate 140 is attached to the pillar 110, the curtain rail 130 is moved downward by a height corresponding to the height of the anchor 400, and both ends thereof are attached to the pillar 110 (FIG. 5). ). In this state, the lower end of the curtain rail 130 also moves downward by a height corresponding to the height of the anchor 400.
In this way, by lowering the curtain rail 130 by an amount corresponding to the height of the anchor 400, the lower end of the curtain 300 can be placed along the edge of the ground. The distance that the curtain rail 130 should be lowered increases as the height of the anchor 400 increases.
The positions of the lower ends of the plurality of holes 112 are the tallest anchors that are expected to be the positions of the lower ends of the curtain 300 when the second fixing plate 140 is attached to the column 110 using the two lowermost holes 112. In the case of using 400, it is provided at a position just along the ground. The range where the hole 112 was provided among the pillars 110 is a specific range in the present invention. The lower end of the specific range is as follows, that is, the distance from the lower ends of the two columns 110 to the lower end of the specific range in the two columns 110 is the distance and the lower end of the column 110 by the anchor 400. The distance combined with the maximum distance planned to be lifted off the ground (that is, the height of the tallest anchor 400 scheduled) is equal to or smaller than the length of the vertical dimension of the curtain 300. Has been determined to be.
As described above, the hole 112 may extend to the lower end of the column 110. In this case, theoretically, even if the height of the anchor 400 reaches the uppermost hole 112, the lower end of the curtain 300 can be moved along the edge of the ground.

As described above, when the curtain rail 130 is lowered in correspondence with the use of the anchor 400, a gap is generated between the curtain rail 130 and the land beam 120. Occurs.
This is done as follows.
FIG. 6A shows a side view of a portion of the curtain structure 100A of the tent in this embodiment. However, FIG. 6A is a side view in a state where the anchor 400 is not used.
The covering material 500 covers the front side of the pillar 110. And the lower end is drawn in to the back side of curtain structure 100A through a slight gap between land beam 120 and curtain rail 130. The other part of the covering material 500 is fixed by, for example, being tied to the pillar 110 or the roof aggregate 210 using a string attached to the back side of the covering material 500, for example.
On the other hand, the lower part of the covering material 500 is in a state of being wound on the back side of the curtain structure 100A in a state of being wound in a roll shape. The roll-shaped covering material 500 is bound to the land beam 120 by a string 510 attached to the back side of the covering material 500 near the land beam 120. Thereby, the roll-shaped part mentioned later of the coating | covering material 500 keeps the state which is not unrolled. Another cord 520 is attached to the tip of the roll-shaped covering material 500.
FIG. 6B shows a state in which a gap is generated between the curtain rail 130 and the land beam 120 by lowering the curtain rail 130. When a gap is generated between the curtain rail 130 and the land beam 120, the string 510 is unwound and a lower portion of the covering material 500 wound in a roll shape is connected between the curtain rail 130 and the land beam 120. It draws out from the gap between them to the front side of the curtain structure 100A. And the clearance gap between the curtain rail 130 and the land beam 120 is covered by the lower part of the drawn covering material 500. The length of the wound covering 500 is equivalent to the height of the tallest anchor 400 planned. Therefore, it is possible to surely cover the gap between the curtain rail 130 and the land beam 120 by the lower portion of the covering material 500 wound in a roll shape. In this state, the lower end of the covering material 500 is tied to the curtain rail 130 by another string 520. Thereby, the lower end of the covering material 500 is fixed to the curtain rail 130.
Note that the strings 510 and 520 are not necessarily fixed to the covering material 500, and can be fixed to the covering material 500 later. In order to fix the string at an appropriate position of the covering material 500 or to allow the string to pass therethrough, a plurality of holes may be formed at appropriate positions of the covering material 500. However, it is obvious that the method of fixing the covering material 500 to the land beam 120 or the curtain rail 130 is not limited to the above.
Further, a rectangular lower covering material 550, which is a film material different from the covering material 500, is prepared, and the lower covering material 550 covers the gap between the curtain rail 130 and the land beam 120. Good (FIG. 6C). In this case, for example, the lower end of the covering material 500 and the upper end of the lower covering material 550 can be fixed to the land beam 120 with a string 530, and the lower end of the lower covering material 550 can be fixed to the curtain rail 130 with a string 540. is there.

  As shown in FIG. 5, this tent can follow the lower end of the curtain 300 to the edge of the ground even when the anchor 400 is used.

The tent can change the height of the curtain rail 130 with respect to the pillar 110, so that the curtain 300 can be used with or without the anchor 400, even when the height of the anchor 400 is changed. It is possible to make the lower end of the state along the edge of the ground.
Moreover, even when the tent once used is disassembled and reused, the height of the curtain rail 130 relative to the pillar 110 can be changed, which is convenient when the tent is reused.

<Modification>
A front view of a tent curtain structure 100A according to a modification is shown in FIG.
This tent basically has the same configuration as that of the tent shown in the above-described embodiment shown in FIG. As the configuration of this tent, all the portions other than the curtain structure 100A can adopt the same configuration as the tent of the above-described embodiment.
A difference between the curtain structure 100A of the tent and the curtain structure 100A of the above-described embodiment is the configuration of the curtain 300. The curtain 300 described above has a horizontal dimension that substantially coincides with the interval between the pillars 110 standing on the left and right of the curtain structure 100A. However, the horizontal dimension of the curtain structure 100A in this embodiment is two pillars. The lateral dimension is much smaller than the interval of 110, more precisely, less than ¼ of the interval between the two pillars 110. And there are two curtains 300.
Further, the curtain 300 in this modified example includes a frame-shaped frame member 370 in which, for example, thin metal plates are assembled into a rectangle, and the same film material as that in the above-described embodiment is included in the frame member 370. The frame film material 380 is stretched over.
The curtain 300 in the modified example can also move left and right while being guided by the curtain rail 130 along the length direction of the curtain rail 130 by the suspension member 133. As a result, the curtain 300 can be opened between the two curtains 300 by moving the curtain 300 on the left side in FIG. 7 further to the left side and the curtain 300 on the right side in FIG. 7 further to the right side. ing. The curtain 300 in this embodiment functions as a door rather than a so-called curtain.
7 is a wall film material 391 in the space between the left curtain 300 and the left pillar 110, and the wall film material 392 is in the space between the right curtain 300 and the right pillar 110 in FIG. It is stretched out.

The tent of this modified example is also changed to the height of the anchor 400 by moving the curtain rail 130 up and down in both cases where the anchor 400 is not used and when the anchor 400 is used and when the anchor 400 is used. Even in the case where there is, the lower end of the curtain 300 can be moved along the edge of the ground.
In that case, it is necessary to adjust the lengths of the wall film materials 391 and 392. For example, other anchors are placed in the portions, the gaps are filled with other film materials, or FIG. As described with reference to), the wall film materials 391 and 392 can be appropriately handled by leaving the lower ends of the wall film materials 391 and 392, for example.
