Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a device for tensioning a stretched sheet in a sheet-stretched house formed by stretching a sheet by supporting both side edges of the sheet with side-by-side guide rails.

[0002]

[Prior art]

 In a seated house, there may be problems such as the sheets being blown by strong winds or rainwater accumulating on the sheets. Therefore, in the past, measures were taken to reduce the distance between the bones over which the sheet is stretched, or to stretch the sheet strongly from the beginning.

[0003]

[Problems to be solved by the invention]

 However, if the distance between the bones over which the sheets are spread is reduced, the number of structural materials increases, the cost increases, and the number of sheets increases, so that it takes much time to open and close. In addition, if the sheet is strongly stretched from the beginning, the friction between the side edges of the sheet and the guide rails increases, which causes a problem that opening and closing of the sheet becomes difficult.

[0004] The present invention has been made to solve such a problem, and the sheet can be easily opened and closed without increasing the number of structural materials and the number of sheets. The purpose of the present invention is to provide a sheet tensioning device for a sheet-stretched house that can easily tension a stretched sheet in order to prevent the water from being swirled or rainwater from collecting on the sheet.

[0005]

[Means for Solving the Problems]

 The seat tensioning device of the seating house according to the present invention comprises two house-shaped tensioning sheet support members (5) arranged in parallel at an intermediate position between adjacent guide rails (3). A belt-like bag (4p) is attached to a portion of the sheet (4) corresponding to the center line between the support members, and a tension belt (7) is inserted into the belt-like bag of this sheet, and both ends of the tension belt are provided. A tensioning tool (8) is provided to draw and tension the lower part of the house.

In the seat tensioning device according to the present invention, the guide rail (3) supports both side edges of the sheet (4), stretches the sheet into a roof shape, and then inserts the sheet into the belt-like bag (4P) of the sheet. When the both ends of the belt (7) are strongly pulled toward the lower fixing portions of the house with the tensioning device (8) and tensioned, the tensioning belt supports the roof-tensioned sheet with two tension sheets. When the sheet is pulled down strongly between the members, the sheet has a V-shaped valley shape, and the other flat portions of the sheet are also tight.

[0007]

[Embodiment of the invention]

 Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 and 2 show an embodiment of a seat tensioning device for a seating house according to the present invention. 1A and 1B show a sheet-stretched house, wherein FIG. 1A is an overhead view showing a situation where a stretched sheet is being tensioned, and FIG. 1B is a view showing the vicinity of a tensioning device. 2 shows a cross section of the sheet, (A) is a view showing a state before being stretched and stretched, (B) is a view showing a state after being stretched, and (C) is an enlarged view of a state after being stretched.

In the figure, 2 is a main structural material of a house, 3 is a guide rail, 4 is a sheet, 4p is a band-like bag, 5 is a tension sheet support material, 6 is a purlin material, 7 is a tension belt, and 8 is a tension device ( Turnbuckle).

As shown in FIG. 1, the main structural member 2 having a house (roof) shape is the most important structural member that determines the shape and strength of the house, and includes a ridge 21, a purlin 6, and a lower fixing portion. 23 and so on. The guide rail 3 is attached to the main structural member 2, and has a round groove 3s as shown in FIG. The sheet 4 has an enlarged portion 4b formed by winding a non-twisted cord on both side edges thereof. By inserting the enlarged portion 4b into the round groove 3s of the guide rail 3 and sliding it, the adjacent guide rails are formed. Sheet 3 is extended between 3 to form a house.

The tension sheet supporting members 5 have the same roof-type shape as the main structural member 2, and are provided in parallel at two positions in the middle of the adjacent main structural members 2. It is attached to the material 6 and the lower fixing part 23. Since the tensioned sheet supporting member 5 comes into contact with the sheet 4, it is preferable to use a tubular material so as not to damage the sheet 4. The interval between the two tension sheet support members 5 is such that when the tension belt is pulled down by a tension member (turnbuckle) 8 described below and tightened, the sheet 4 is pulled down between the two tension sheet support members 5 and V The sheet 4 is determined to be tensed by being depressed in a valley shape.

As shown in FIG. 2, a belt-like bag 4 p is attached to the inner surface of the sheet 4 which is located at the center line of the two tension sheet support members 5, 5. It is inserted into the band-shaped bag 4p.

As shown in FIG. 1B, a triangular ring 78 is attached to the end of the tension belt 7, and a tensioner (turn buckle) 8 is provided between the triangular ring 78 and the lower fixing portion 23. The tension belt 7 can be pulled down strongly when worn.

Next, the operation of the seat tensioning device of the seating house according to the invention shown in the drawing will be described. After the entire framework of the house is completed, the enlarged portions 4b on both side edges of the sheet 4 are inserted into the round grooves 3s of the guide rail 3, and both ends of the sheet are pulled so that the inside of the round groove 3s of the guide rail 3 is inserted. The sheet 4 is extended by sliding the enlarged portion 4b. Note that both end edges of the sheet 4 are attached to the lower fixing portion 23.

Next, as shown in FIG. 1B, a tensioning tool (turnbuckle) 8 is applied between the triangular ring 78 at the end of the tensioning belt 7 and the lower fixing portion 23, and the turnbuckle 8 is turned. Pull the tension belt 7 down. Then, since the seat 4 is stretched in a house shape or a roof shape, that is, a mountain shape, the tension belt 7 tightened by the turnbuckle 8 pulls down the stretched sheet 4, and as shown in FIG. Is dented in a V-shaped valley between the tensioned sheet support members 5, so that the entire sheet 4 is taut.

If a plurality of eyes 82 and eye rings for hooking a tensioner (turnbuckle) 8 on the lower fixing portion 23 are installed at a plurality of places having different heights, the length of the tension belt 7 is extended by use. It is possible to cope at times. In addition, a rigging tackle or the like used in a sailing boat may be used as the tensioning tool 8.

[0016]

[Effect of the invention]

 As described above, the sheet tensioning device of the sheet-tensioned house according to the present invention is configured such that the tension belt 8 is used to pull down and tighten the tension belt 7 so that the sheet 4 is recessed in a V-shaped valley between the tension sheet support members 5. The entire seat 4 can be tense and taut. This prevents rainwater from flowing down the V-shaped valley and accumulating on the sheet without being forced by the strong wind, eliminating problems such as breakage of the sheet and the useful life of the sheet. Becomes longer.
