Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a foldable tent.

[0002]

2. Description of the Related Art Recently, tents of the type that supports the roof curtain with columns called canopies or tarps are mainly folding frame type tents, and those that can be installed and stored as easily as possible with one touch. Is a hot selling item. As a typical example of such a foldable tent,
As disclosed in Japanese Patent Publication No. 8-508799.

This conventional tent has four legs (posts).
It has a structure consisting of a scissors-shaped peripheral truss means having ends attached to it and central scissors-shaped central truss means provided so as to connect the facing middles of the peripheral truss means on the four sides, so-called magic hand. It can be easily folded and expanded like this.

[0004]

In the above-mentioned prior art, the point at which the roof curtain is supported by the five points of the central apexes of the peripheral truss means of four sides and the central apex formed by the central truss means connecting these sides. Since it is a support structure, it has the improvement point that the roof curtain slacks and water easily collects when it rains.

Further, a truss means having a total of 6 sides of 4 sides connecting between the legs and 2 sides connecting the centers of these 4 sides is required, and there is a possibility that the trusses are entangled with each other during installation / storage work.
There are many parts and the appearance is complicated.

The present invention is intended to solve such problems, and provides a tent that is simpler and easier to fold, while reviewing the support structure for the roof curtain.

[0007]

A tent according to the present invention comprises three or more strut units, and a truss unit hung between the strut units so as to form a side portion of a plane figure formed with these strut units as corners. A roof support unit hung from each of the pillar units to an apex located at a central portion of a plane figure formed by using the pillar unit as a corner, and each truss unit hinges two rod-shaped members at intermediate positions with respect to each other. X connected to each other and at least one of the rod-shaped members is provided with a hinge shaft at a position deviated from the center X
A structure in which at least four frames are connected, and the upper side of the free ends of the X frames located at both ends are pivotally supported on the strut unit and the lower side is slidably supported along the strut unit. In addition, the roof support unit is a purlin frame whose base end is pivotally supported by the strut unit and spans to the apex, and the base end is slidably supported along the strut unit and the tip is the purlin frame. It is characterized by having a structure consisting of a cane frame hinge-connected in the middle of the.

In this tent structure, with respect to the X frame of the truss unit, two bar-shaped members are not hinge-connected to each other in the middle, but at least one bar-shaped member is offset-connected with the hinge axis at a position deviated from the center. Since at least four such X frames are connected to form one truss unit, the truss unit can be curved in an arch shape when the tent is expanded. This makes it possible to increase the head clearance and improve the habitability.

In such a tent of the present invention, installation and storage are performed by a simple operation of sliding or closing the lower side of the free end of the truss unit and the base end of the cane frame and closing or expanding the column units. You can work. Moreover, as the roof support unit, since the purlin frame from the pillar unit to the top of the center of the tent is included,
Since the roof curtain is supported by "lines", the roof curtain is less likely to sag than the conventional point support structure. In particular, the highest part of the arched truss unit can be located higher than the upper end of the pillar unit. In this case, when the roof curtain is stretched, the space between the purlin frames A ridge line supported by the truss unit highest portion and the apex portion is formed in the valley portion. According to this support structure, the ridgeline is formed in the valley portion where water easily collects, so that the water pool can be almost eliminated.

Further, since the roof support unit serving as a purlin may be rod-shaped, it has a simpler structure than the conventional truss type, has a small number of parts, and is not easily broken. Moreover, when the support unit is expanded and installed, the truss unit becomes a beam connecting the sides between the supports and the roof support unit becomes a beam connecting the diagonal lines between the supports, so the support structure between the supports is extremely difficult. Is getting stronger.

If the purlin frame of the roof support unit is of a center-folding type and the pillar unit is of a telescopic type in which a large-diameter pipe and a small-diameter pipe are slidably connected, it can be stored very compactly. Is.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a perspective view of the folding tent 1 of this embodiment in a state where the support unit 10 is expanded. There are four pillar units 10 in this example, and therefore, the planar figure formed when the pillar units 10 are expanded is a quadrilateral having four pillar units 10 at the corners (see FIG. 4). Four truss units 20 are bridged as beams on the sides between the pillar units 10. Further, a roof support unit 30 is bridged between the apex portion T located at the central portion of the quadrangle and each pillar unit 10 to form a diagonal line of the quadrangle.

As shown in FIG. 2, each strut unit 10 is of a telescopic type in which a large-diameter pipe 11 and a small-diameter pipe 12 slidable in the large-diameter pipe 11 are combined, and the height is appropriately adjusted. It can be adjusted and stored compactly. Although the illustrated example is a two-stage telescopic type, if the number of stages is increased, it becomes possible to store the device compactly.

Each truss unit 20 forming a side between the columns and acting as a beam has the same structure, and an X frame 23 in which a first rod-shaped member 21 and a second rod-shaped member 22 are hinge-connected in the middle is used. Has a structure in which four are connected. Of the free ends 24 and 25 of the X frame 23 located at both ends of the connected body, the upper free end 24 is pivotally supported on the upper end of the column unit 10, while the lower free end 25 is the column unit. It is slidable along 10 and is pivotally supported. That is, the lower free end 25 is pivotally supported by the slider 13, which is a component that slides through the column unit 10. As a result, the pillar unit 1
When the slider 13 is slid downward with the action of closing 0, the X frame 23, that is, the truss unit 20 is naturally folded like a magic hand,
It can be stored compactly.
The slider 13 may be provided with mooring means such as elastic pins and pin holes so that the slider 13 can be moored at the top dead center and the bottom dead center.

As shown in detail in FIG. 2B, the first rod-shaped member 21 and the second rod-shaped member 22 forming each X frame 23 of the truss unit 20 have different hinge shaft positions. is there. That is, both rod-shaped members 21, 22
Although the total length d is the same, comparing the length d1 from one end of the first rod-shaped member 21 to the hinge shaft with the length d2 from one end of the second rod-shaped member 22 to the hinge shaft,
The length of d2 is shorter. That is, at least the hinge shaft of the second rod-shaped member 22 has an offset design that is off-center. By configuring the second rod-shaped member 22 to be the free end 24 that is pivotally supported on the upper end of the strut unit 10, the truss unit 20 has an arched shape in which the central portion becomes higher than both ends when expanded. Therefore, a large overhead clearance can be secured. In addition, in this example, the hinge shaft of the first rod-shaped member 21 is also formed at a position slightly decentered (not d1 = d / 2) so that the four X frames 23 are connected without any problem. is there.

The truss unit 20 having such four sides
In addition to the diagonal lines between the columns, the roof support unit 30 of this example, which plays the role of a purlin, has a tip supported by the apex T and a base supported by the upper end of the strut unit 10. It is composed of a frame 31 and a cane frame 32 whose tip is axially supported in the middle of the purlin frame 31. The base end of the cane frame 32 is pivotally supported by the slider 13 so as to slide with the free end 25 of the truss unit 20. Note that a slider for the cane frame 32 may be provided separately from the slider 13 for the free end 25, but it is better to operate together with it. In addition, the purlin frame 31 has a middle bent portion 33 provided in the central portion.
It can be bent in half.

The purlin frame 31 and the cane frame 3
Due to the combination of the two, the roof support unit 30 as shown in FIG. 3, when the slider 13 is slid downward together with the operation of closing the pillar unit 10,
As a result of being pulled by 2, the purlin frame 31 is bent at the middle folding portion 33, so that it can be stored compactly by a simple operation.

FIG. 4 shows a plan view of the above-mentioned tent 1 expanded and the roof curtain R stretched, as seen from above. As shown in the figure, the truss unit 20 is arranged on the side portion between the pillar units 10 forming the corners of the quadrangle, and the roof support unit 30 is arranged on the diagonal line portion between the pillar units 10. It can be seen that the support for 10 is very strong.

The purlin frame 31 of the roof support unit 30 is linearly arranged so as to form a diagonal line.
As a result, the roof curtain R is linearly supported, so that the roof curtain R is unlikely to loosen. Further, the ridge lines Ra formed by the support of the apex portion T and the highest portion of the truss frame 20 are formed in the valley line portions between the ridge lines Rb formed by the support of the purlin frame 31, respectively, and very rainwater It can be seen that the form is such that it does not easily accumulate.
