Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a tent structure that opens and closes like an accordion, and is always comfortable to use as a venue for sports and other events by being fully open during fine weather and closed during bad weather. The present invention relates to a novel tent structure that can be used for various purposes and that can emphasize the fashionability, appeal, and symbolism unique to flexible tent structures.

(Prior Art) As a conventional tent structure that can be opened and closed, an accordion-shaped tent structure is known. As shown in the front view in Fig. 14 and the side view in Fig. 15, this tent structure has a cross-sectional structure made of a steel frame 21, and a large number of these steel frames are stacked on two parallel rails 22, 22' on the left and right sides. , are connected by an X-shaped link 23, and a sheet-like body is attached to the frame.

(Problems to be Solved by the Invention) However, such tent structures have the following drawbacks, and are never used for fancy events such as sports, but are mainly used for storage. This is the reality.

() When the steel frame is large, especially in width, it is expensive because the frame needs to have a sturdy structure.

() Has poor fashionability due to its common shape.

() Many wrinkles remain on the tent surface, which is unsightly,
Parts of the tent are severely deteriorated due to sunlight, dirt, etc.

(Means for Solving the Problems) Therefore, it is an object of the present invention to provide a tent structure with excellent fashionability that can be used in spectacular event venues such as sports. That is, in the present invention, two rails, upper and lower, each having a large number of rotatable sliding bodies attached thereto, are provided in parallel on both sides, and a rope is fixed to the sliding bodies attached to the pair of upper rails, so that a rope can be secured between the rails. A number of upper ropes are suspended, the ropes are fixed to sliding bodies attached to the pair of lower rails, a number of lower ropes are suspended between the rails, and an upper rope is suspended between the upper rope and the lower rope. A saw blade-shaped tent is formed by stretching a sheet-like body so that the central part of the rope is concave and the central part of the lower rope is convex, and the sliding body to which the rope is fixed is rotated. This is an opening and closing type tent structure characterized in that the tent is configured to open and close in an accordion shape.

(Function) The tent structure of the present invention forms a saw-blade-shaped tent by stretching two ropes between the upper rope and the lower rope in a tensioned state, so a small frame can be used. Moreover, there are no wrinkles in the tent, and the unique curvaceous beauty of the tent can be expressed. Furthermore, by moving the sliding body to which the rope is fixed, the tent can be opened and closed in an accordion-like manner as appropriate.

(Example) Next, an example of the tent structure of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of the tent structure, and ′ are upper rails installed parallel to each other for tensioning and sliding the upper rope; and ′ are upper rails for tensioning and sliding the lower rope in pairs. It shows the lower rails installed parallel to each other for sliding. A sheet-like body is stretched between the upper rope and the lower rope so that the upper rope is curved downward in a concave shape at the center, and conversely, the lower rope has a convex shape at the center. The sheet-like body is connected by stretching these ropes one by one from bottom → top → bottom → top, and the upper rope lifts the sheet-like body, while the lower rope pushes down the sheet-like body, so that the sheet surface The upper rope line forms the mountain peak line, the lower rope line forms the valley line, and the whole forms a sawtooth tent. The above upper rope and lower rope are respectively an upper rail, ' and a sliding body (not shown) that rotates inside the lower rail, '.
is fixed. As this sliding body, for example, an electric motor directly connected to a reducer is provided and driven in synchronization with the rail part, and the rope is moved onto the rail while keeping the upper rope and the lower rope in a mutually parallel state by the related synchronized drive of the electric motor directly connected to the reducer. It is possible to have a structure that allows parallel movement. In addition, as shown in Fig. 4, which is a cross-sectional view of the rail, a hanging ring for fixing the rope is protruded from a slit-like opening provided in the rectangular cylindrical rail between a pair of ropes moving within the rail, and a large number of sliding bodies are installed. The slider may be accommodated in a rail, and the first slider among these sliders may be fixed to a rotatable endless chain band as shown in FIG. The endless chain band mentioned above is rotated by a motor.
Moreover, this chain belt passes through the pipe adjacent to the rail and inside the rail, as shown in FIG.

The tent structure of the present invention can be moved from the pitched state as shown in the side view in FIG. 2 to the tent structure compactly stored in the right corner as shown in FIG. 3 by driving the sliding body to open the upper house. Can be done.

This storage method not only allows storage on one side as shown in Fig. 3, but also allows the storage to be divided into two parts in the center and separated into left and right corners for storage.

The sheet material that makes up the tent can be made of sheet materials used for so-called tents, such as woven fabrics made of synthetic fibers or natural fibers, woven fabrics coated with plastic, plastic sheets, or thin metal plates such as stainless steel or aluminum. can.

The upper and lower ropes for tensioning the sheet-like body can be selected from synthetic fiber ropes, natural fiber ropes, wire ropes, etc. depending on the shape and size of the tent structure. When emphasizing fashionability, it is preferable for the rope to be as thin as possible. For this reason, wire ropes are usually used.

The tent structure of the present invention is usually used with the sides open as shown in Fig. 1 when the inside of the upper house is made open. In order to have a It is also possible to attach a sheet-like member to the side surface portion indicated by diagonal lines to cover a part of the side surface, or to seal the side surface indicated by diagonal lines as shown in FIG. In this case, as shown in the front view of FIG. 8, a completely sealed tent structure can be obtained by attaching a sheet-like body to the lower opening shown by diagonal lines. Furthermore, as shown in Figure 9, sheet-like materials are placed on the sides, and mesh plastic nets are used in the areas shown in Figure 9 to maintain breathability while mitigating direct blows from rain, snow, and wind. You can also. In this case, the eighth
It is preferable to attach a breathable plastic net to the lower opening shown in the figure.

Furthermore, as shown in FIG. 10, a single-flow type structure can also be used. Such tent structures can be used, for example, in swimming pools with bleachers. In this case, this side is completely open so that it can be easily seen from the audience seats.
This is an example of saving money by setting up a roof only in the pool area to protect it from the rain, as there are not always spectators like in swimming competitions, but if the cost allows, you can also include the seats for the spectators. It is also possible to make the entire structure single-flow type.

FIG. 12 is a view taken along the line A-A in FIG. 12; In the figure, the upper rope rail ′ and the lower rope rail ′ are installed in parallel as concentric circles cut out, and the upper and lower ropes are
Or indicating a shelter such as a flexible tent. In this structure, the opening and closing of the tent forming the upper house is carried out in the tent structure shown in Figure 1, except that electric motors and controllers are installed so that the opposing wire ropes slide at a certain angle and are folded and stored. It's the same as the body.

In FIGS. 10 to 13, the same reference numerals are used in the same places as in FIG. 1, and the explanation thereof will be omitted.

(Effects of the Invention) As described above, the tent structure of the present invention, which opens and closes like an accordion, has a sheet-like body stretched between the ropes, so the strength of the frame constituting the shed is greater than that of the conventional tent structure. It can be reduced and provided at low cost. In addition, since the sheet-like body is stretched, it has the unique curvaceous beauty of a tent, and by applying colorful colors to the sheet-like body, it can express gorgeousness, and is especially suitable for tent structures at sports and other event venues. It is useful as
