Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a telescopic tent structure having a small number of members, a simple structure, and a compact outer dimension.
[0002]
[Prior art]
Conventionally, a bellows-type warehouse tent structure is known as a tent structure that can be freely expanded and contracted. As shown in FIG. 10, the bellows-type warehouse tent structure includes end frames 50 and 51 in which two frame members are assembled as trusses with a lateral connecting member and a diagonal member, and these ends. The intermediate frames 52, 52... Arranged in the middle of the part frames 50, 51 are connected by X-shaped horizontal connecting members 53, 53 (hereinafter referred to as X bar members), and the outer surfaces thereof are covered with a film material. Of structure. As shown in FIG. 11, the X bar member 53 has lower ends of both diagonal members fixed together, and the upper end is slidable in the height direction of the frame. One end frame 50 (51 ) And intermediate frames 52, 52... Are moved to the other end frame 51 (50) side, whereby the X bar member 53 is folded, and the tent structure is configured to be extendable or retractable.
[0003]
[Problems to be solved by the invention]
However, when the intended use is to protect items etc. that are stored or left outdoors, or to prevent the spread of strange odors such as those with strange odors, the above-mentioned bellows type warehouse tent structure has a large size. It is too inconvenient to handle.
[0004]
That is, in the case of a telescopic tent roof structure using the conventional X bar member 53, the frame height must be determined in consideration of the slide length of the X bar member 53. The size cannot be reduced, and the X bar members 53, 53... Have a width that can be folded. Therefore, the volume ratio at the time of folding (volume ratio with respect to the entire deployment) can be usually only about 40%. There were problems such as lack of storage and portability.
[0005]
Further, in addition to the frame groups 50 to 52 as the main frame members, the X bar members 53, 53... Connecting them are required, so that the number of members increases, and as shown in FIG. There is a problem that the X-bar member 53 must be slidable on the wall frame portion of .about.52, and the structure becomes complicated and much labor is required.
[0006]
Accordingly, the main problems of the present invention are that the number of members is small, the structure is simple, the outer dimensions can be made compact, the dimensions at the time of contraction can be made smaller, and the storability and portability are excellent. The object is to provide a telescopic tent structure.
[0007]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention provides a tent structure composed of a telescopic frame structure that can be assembled using an arch chord material as a frame member, and a sheet-like membrane material that is stretched over the telescopic frame structure. Because
The telescoping frame structure has the two arch chord members as a set, intersects the arch chord members on both sides of the arch chord member, and supports the cross point by a shaft member so that it can be opened and closed in an X shape. The arch chord material unit is arranged in the longitudinal direction, and the arch chord material units are connected to each other so as to be rotatable around the horizontal axis between adjacent arch chord material units. It can be extended and contracted by a structure in which the lower ends are connected so as to be rotatable around a horizontal axis .
The sheet-like film material is joined along the arch chord material on one side of the two arch chord materials on the one side of the tent structure center line in the joining relationship with each arch chord material unit, The other side of the arch chord material is stretched by joining along the other arch chord material on the other side of the center line .
[0008]
As a method of stretching the sheet-like membrane material that does not hinder the expansion and contraction of the telescopic frame structure , two arch chord members on one side of the tent structure center line in the connection relationship with the arch chord member units Of the two arch chords, and the other arch chord is joined by joining along the other arch chord. The structure is adopted. The advantage of this method is that the sheet-like membrane material is more integrated with the framework structure, so that it can be folded neatly and handled easily.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is an overall perspective view of a telescopic tent structure 1 according to the present invention, FIG. 2 is a plan view, and FIG. 3 is a cross-sectional view.
[0010]
As shown in FIG. 1, the telescopic tent structure 1 includes a framework structure 3 that is constructed to be stretchable by using semi-arc-shaped arch chords 2, 2,. This is a tent structure having a substantially vault shape, which is constituted by the stretched sheet-like film material 4. The main uses are for protection of materials stored outdoors, storage of fertilizers, compost, etc., protection and temporary storage of agricultural crops, etc.
[0011]
[Frame structure]
The assembly of the frame structure 3 is performed by crossing the arch chords 2 and 2 on both sides of the arch chords 2 and 2 as a set, and the crossing point is pivoted by the shaft member 6. Assembling a plurality of arch chord material units 5, 5. More specifically, as shown in FIG. 3, a pair of two arch chords 2 and 2 are overlapped while being slightly shifted in the horizontal direction so that the arch chords 2 and 2 on both sides intersect each other. Next, a plurality of arch chord material units 5, 5,. Assemble 8 bodies.
[0012]
Next, the arch chord material units 5 are arranged in a column direction, and the apex portions of the arch chord materials 2 and 2 are connected to each other between the adjacent arch chord material units 5 and 5 so as to be rotatable around a horizontal axis. The lower ends of the chords 2 and 2 are connected to be rotatable about a horizontal axis.
[0013]
For example, as shown in FIG. 5, the top connecting structure of the arch chord members 2 and 2 fixes a flange 10 formed with a through hole by welding or the like, and superimposes the flanges 10 and 10. By inserting the shaft member 11 penetrating through the ten through holes, the shaft is connected so as to be rotatable around the horizontal axis with the connecting portion as a center point.
[0014]
On the other hand, the connecting portion structure between the lower ends of the arch chords 2 and 2 is such that the lower ends of the arch chords 2 and 2 are overlapped in the width direction of the tent and the lower ends of these arch chords 2 and 2 are horizontally oriented. By inserting the penetrating shaft member 12, it is connected so as to be rotatable about a horizontal axis.
[0015]
Furthermore, both end faces bring in the end arch chord material 7 having the same shape, and connect the top portions of the arch chord materials 2 and 7 so as to be rotatable around the horizontal axis. The adjacent arch chord material unit 5 is connected to the lower end of the arch chord material unit 5 by the auxiliary arch chord material 8 so as to be rotatable.
[0016]
The frame structure 3 is stretched as shown in FIG. 6 when used, and protects materials stored outdoors from wind and rain, and stores odors such as fertilizer and compost so that they do not diffuse outside. When not in use, as shown in FIG. 7, it is shrunk and stored in a warehouse or the like.
[0017]
The feature of the frame structure according to the present invention is that the arch chords 2 and 2 which are the frame members have a structure which also serves as the conventional X-bar member 53 (see FIG. 10). Therefore, since the X bar member 53 is not required, the number of members can be reduced correspondingly, and the structure can be simplified. Also, the dimensions during storage can be reduced, and the storage and portability are excellent. Furthermore, since it is not necessary to secure the sliding allowance of the X-bar member 53 on the wall portion of the conventional frame member, there are advantages such that the outer dimensions can be made compact.
[0018]
[Stretch structure of membrane material]
In the case of a conventional telescopic structure using an X-bar member, the end frames 50 and 51 and the intermediate frames 52, 52... Are arranged in parallel, so that they can be expanded and contracted even when the membrane material is joined to the frame group. . However, in the skeleton structure of the tent structure according to the present invention, the arch chord members 2, 2... Are not arranged in parallel, and when the membrane material is joined to each arch chord member 2, 2,. 3 will not be able to expand and contract.
[0019]
Accordingly, in the tent structure 1, two methods are proposed as a method of stretching the sheet-like film material 4 that does not inhibit the expansion and contraction of the frame structure 3. First, the first method is shown in FIG. In the drawing, a portion joined along the framework is indicated by a solid line, and a portion not joined is indicated by a dotted line.
[0020]
FIG. 8B illustrates the joining structure of the arch chord material unit 5 taken out as a single unit. In this membrane material stretching method, the sheet membrane material 4 is divided into two pieces on one side of the tent structure center line L as a boundary. The arch chords 2 and 2 are joined along one arch chord, and on the other side of the center line L, the two arch chords 2 and 2 are along the other arch chord. Are joined together. As shown in the overall plan view of FIG. 8 (A), the joining line is just a joining shape in which connecting lines 13, 13.. Since the joining lines 13, 13... Are parallel, the stretched sheet-like membrane material 4 is stored while being folded without hindering expansion and contraction of the frame structure 3.
[0021]
Next, as shown in FIG. 9, the second method is to connect the connection points (shaft member 6 site) on both sides of the arch chord material 2, the connection points (shaft member 11 site) on the top of the arch chord material, and the arch chord. In this method, each connection point of the lower end portion of the material (the shaft member 12 site) is stretched as a locking portion. Since the sheet-like film material 4 is stretched with the connection point portion of the arch chord materials 2, 2... As the support point, the parallel relationship between the film material support points is maintained. The film material 4 does not hinder expansion and contraction of the frame structure 3 and is stored while being folded.
