Description

[0001]
BACKGROUND OF THE INVENTION
The present invention belongs to a technical field such as a temporary tent or a temporary house used as a temporary pool house, an agricultural house, an industrial simple warehouse, or the like.
[0002]
[Prior art]
Conventionally, this type of house has a structure in which a sheet material is covered with a framework using a lightweight steel frame such as a metal pipe, and many of them are configured so that the house can be expanded and contracted according to the purpose of use and the situation. . And as this expansion / contraction method, for example, a plurality of frames are connected by a wire, and when the frame is run, the whole frame expands and contracts, or a plurality of frames are connected by a crossbar, There is an accordion type that allows the entire house to expand and contract when the frame is run.
[0003]
[Problems to be solved by the invention]
However, the conventional telescopic house described above has several drawbacks. This will be described below using an accordion-type telescopic house as an example. First, since the frames (spans) facing each other are connected by a cross bar, only a pair of frames forming one span cannot be expanded or contracted. For this reason, even when only a part of the spans are expanded and contracted, all the frames must be run, which requires a great deal of labor. Second, the crossbar is freely rotated while being connected to each frame, and since the force for supporting the frame is weak, the entire frame is easily twisted.
[0004]
Thirdly, since each span defined in the house expands and contracts in an interlocking manner, the sheet material can be stretched only when all the spans of the entire house are extended. For this reason, there is a drawback that the sheet material flutters in the wind or rain accumulates as a result of the sheet material loosening as a whole in the middle of elongation. Further, when the house is contracted, the sheet material of the span is slackened inside the house and is damaged by being sandwiched between the folded cross bars. For this reason, a protective member for preventing biting of the sheet material is provided, or a method of increasing the number of frames and reducing the span between the spans in order to reduce the amount of loosening of the sheet material has been adopted. Has a problem that the structure of the frame is complicated and the price is high.
[0005]
The present invention has been made in view of the above-mentioned drawbacks of the prior art, and can expand and contract only any span among a plurality of spans, so that there is a degree of freedom in use, high rigidity against torsion, and expansion and contraction. It is an object of the present invention to provide a telescopic seat house that can be easily operated.
[0006]

Each side frame member 13 of the subframe 11 is advanced and retracted between the pair of main frames 5 and 5 by a side frame advancing and retracting mechanism 24 comprising four rotating arm members 25, 25,. Connect as possible. At this time, the pair of main frames 5 and 5 that define the span A come close to each other, and the roof-type lifting frame material 12 is in a lowered state, and each side frame material 13 is in an inwardly advanced state. The seat 31 is attached to the frame 1 assembled in this way, and is engaged with each main frame 5.
[0019]
Thereafter, when the main frames 5 and 5 are separated from each other, the side frame members 13 retreat outward, and the roof-type lifting frame member 12 rises. When each side frame member 13 is fixed to the guide rail 2 side by the locking device 28, each rotating arm member 25 is also extended linearly and positioned between the pair of main frames 5, 5, so that one span A is defined. The Finally, the roof-type lifting frame member 12 is pushed up and connected to the side frame member 13 by the frame connecting hardware 14, so that the seat 31 is expanded for each span A with the center of the span A protruding in a mountain shape.

When the side frame member 13 is pushed inward from the guide rail 2 from this state, the rotating arm member 25 rotates and the one main frame 5 in the movable state moves to the other main frame 5 in the fixed state. . Then, the purlin frames 21 and 21 and the reinforcement frames 23, 23,... Supporting the roof type lifting frame member 12 in a substantially horizontal state rotate downward, and the roof type lifting frame member 12 descends. Thus, the span A can be reduced by bringing the pair of main frames 5 and 5 into close contact with each other and folding the loosened sheet 31 between the pair of main frames 5 and 5.
[0021]
Thus, according to the present embodiment, the skeleton 1 can be expanded and contracted for each span A only by pushing one of the main frames 5 defining one span A. In either case of expansion or reduction, only an arbitrary span A can be expanded or contracted without expanding or contracting another span A.

Next, FIGS. 7 and 8 show a second embodiment. In addition, the same code | symbol is attached | subjected to the component same as the component of 1st Embodiment mentioned above, and the description is abbreviate | omitted. In the figure, reference numeral 41 denotes a frame lifting mechanism. 42 and 42 are a pair of purlin frames constituting the frame raising / lowering mechanism, and each purlin frame 42 is interposed between the main frame 5 and the sub frame 11 via hinges 22 and 22 as in the first embodiment. It is erected.
[0023]
Reference numerals 43 and 44 denote a pair of fixed pulleys constituting the frame elevating mechanism 41. The one fixed pulley 43 is provided on the top portion 6A of one main frame 5 that defines one span A, and the other fixed pulleys.

Reference numerals 45 and 46 denote a pair of interlocking wires stretched between the roof type lifting frame material 12 and the side frame material 13 of the subframe 11. Both of the pair of interlocking wires 45 and 46 have one ends 45A and 46A attached to the upper end side of the one side frame member 13, and the other ends 45B and 46B to the lower end side of the other curved portion 12C of the roof type lifting frame member 12. It is attached. A middle portion 45C of one interlocking wire 45 is wound around the one fixed pulley 43 provided on one main frame 5, and a middle portion 46C of the other interlocking wire 46 is provided on another main frame 5. It is wound around another fixed pulley 44.
[0024]
Reference numerals 47 and 48 denote another pair of interlocking wires. The pair of interlocking wires 47, 48 both have one end 47 A, 48 A attached to the lower end side of the one-side curved portion 12 C of the roof type lifting frame member 12 and the other end 47 B, 48 B connected to the upper end of the other side frame member 13. It is attached to the side. A middle portion 47C of one interlocking wire 47 is wound around a fixed pulley 43 provided on one main frame 5, and a middle portion 48C of another interlocking wire 48 is a constant pulley provided on another main frame 5. 44 is wound. Thus, the pair of interlocking wires 45, 46 and the other pair of interlocking wires 47, 48 are stretched between the roof type lifting frame member 12 and the side frame member 13 via the fixed pulleys 43, 44. It is. The present embodiment has the above-described configuration, and unlike the first embodiment, the muscle chi frame 23 is not provided.
[0025]
In the embodiment having the above-described configuration, when the span A of 1 is reduced, the subframe 11 is separated into the roof-type lifting frame material 12 and the side frame material 13, and the same as in the case of the first embodiment. When the side frame member 13 is pushed inward in the lateral direction, the movable main frame 5 is moved on the guide rails 2 and 2 to the fixed main frame 5 side by the frame advance / retreat mechanism 24. Further, when the side frame member 13 moves inward in the horizontal direction, the interlocking wires 45, 46, 47, 48 are loosened, and the roof type lifting frame member 12 is lowered.
[0026]
Further, when extending the contracted span A, the main frame 5 is pushed along the guide rail 2 or the side frame member 13 is pushed laterally outward. As a result, the interlocking wires 45, 46, 47, 48 are pulled to raise the roof-type lifting frame material 12. By connecting the roof-type lifting frame material 12 and the side frame material 13, the frame 1 Span A is in an extended state.
[0027]
According to the said structure, since the muscle chi frame 23 can be made unnecessary, the structure of the frame 1 can be simplified and the roof type raising / lowering frame material 12 side can be reduced in weight. Further, since the roof type lifting frame material 12 is raised and lowered by the fixed pulleys 43 and 44 and the interlocking wires 45, 46, 47, and 48, the expansion and contraction operation can be smoothly performed as compared with the first embodiment. it can.
[0028]
【The invention's effect】
Since the present invention is configured as described in detail above, the following effects can be obtained.
(1) Since the framework can expand and contract not only all of a plurality of spans, but also only a part of the spans, it can be expanded and contracted appropriately as needed for use, and less labor is required.
[0029]
(2) When expanding / contracting the frame, all the spans can be expanded / contracted instead of expanding / retracting at a time. Excellent in properties.
[0030]
(3) Since the position of the main frame and the sub frame that define the span that is not reduced can be kept constant and the form of the frame can be maintained, the rigidity against torsion and the like is high. Therefore, the main frame can smoothly travel during the expansion and contraction work, and the workability is excellent. In addition, a device for preventing torsion is unnecessary, the structure of the skeleton can be simplified, and the manufacturing cost can be reduced.
[0031]
(4) The film material is stretched for each span, and even if some spans are reduced, other span film materials are maintained in the stretched state, so that the strength against wind and rain can be maintained. . Further, since the film material of the reduced span is folded between the main frames, the film material is not crushed or fluttered by the wind.
[0032]
(5) Since the frame elevating mechanism and the side frame advancing and retracting mechanism are interlocked by simply pushing the main frame that defines the span, the expansion and contraction of the seat house can be performed easily and efficiently. .
