Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a foldable tent including a beam member that operates in a scissor shape with respect to a column member via a connecting member.
[0002]
[Prior art]
A tent that folds a beam material into a scissor shape has, for example, four column members 12 and four beam members 13 that connect the column members 12 to each other as shown in FIG. An end joint 14 is attached to the top of the column 12 standing on the ground surface, and a slide joint 15 that can move in the vertical direction is mounted below the end joint 14. 14 and the slide joint 15 support one end of the diagonal member 16 of the beam member 13 so as to be rotatable.
[0003]
A hinge joint portion 17 is provided at the center of the beam member 13 to connect the left and right diagonal members 16 by pin connection. A roof link member 18 is attached from the hinge joint portion 17 toward the center of the tent, and they are assembled. A central column 19 for supporting a central portion of a awning (not shown) is disposed at the center. The awning is attached to the frame structure from above.
[0004]
The beam members 13 and the roof link member 18 are all connected by pins, and are configured to be foldable while operating synchronously in a scissor shape. If it is separated from each other, the entire skeleton is expanded. Further, when the column member 12 is brought close to each other during storage, the entire frame can be contracted.
[0005]
[Problems to be solved by the invention]
However, when the folding structure tent is stored with the awning attached to the frame structure, it is particularly easy to sandwich the awning fabric at the intersection of the beam members 13. In the conventional foldable tent beam 13, a rectangular pipe or plate having a rectangular cross section is generally used as the diagonal 16, so that the fabric of the awning is easily sandwiched between the corners of the diagonal 16 and the corners are sharp. Could be damaged.
[0006]
In addition, the conventional connecting member that fastens the end of the diagonal member 16 with a bolt and nut is two parallel support plates or one support plate, but is supported by the bolt tightening condition. In many cases, play occurs between the plate and the diagonal member, and the function as the beam member 13 is unstable.
[0007]
The present invention solves the above-mentioned problem, and even when the tent is stored with the tent attached, it is difficult to insert the fabric of the awning into the portion of the beam material that intersects the scissors. The purpose is to provide a ceremony tent. Another object of the present invention is to provide a foldable tent that can support the beam material stably with little play between the beam material and the connecting member, and that is strong and does not rattle.
[0008]
[Means for Solving the Problems]
To solve the above problem, foldable tent of this invention is a foldable tent having a beam member which operates through a connecting member to a pillar material erected on the ground in scissor-like, the beam member is axially An oblique member having an octagonal cross section that houses a filling member having a cut portion at an end thereof, and a pin that is connected while holding a gap so that intersecting oblique members are separated from each other , It has an external support plate that is in contact with both sides of the rotating diagonal end and a central support plate that penetrates into the notch, and rotates the diagonal end that houses these three support plates and the filling member. It has the fastening member fastened possible, It is characterized by the above-mentioned.
[0009]
When folded, the diagonals rotate with each other in the overlapping direction around the pin, so there may be a tent that hangs down between the overlapping diagonals, but the gap is kept so that the diagonals do not adhere to each other at the intersection. On the other hand, since the corners of the diagonal member are octagonal in cross section, the distance between them increases and it becomes difficult to sandwich the awning. In addition, there is no risk of the fabric being damaged because of the spread even if it is sandwiched.
[0010]
As the filling member, a molded material made of synthetic resin or various metals is used.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a front view showing a connecting portion between a column member and a beam member, and FIG. 2 is an enlarged sectional view showing a II-II section of FIG. The beam member 2 that connects the column members 1 of the tent connects the two diagonal members 3 and 3 with a pin 4 in a scissor shape. An end joint 5 is attached to the top of the column 1 and a slide joint 6 is loosely inserted below the end joint 5. The crossing angle of the diagonal member 3 can be changed by moving the slide joint 6 up and down.
[0012]
As shown in FIG. 2, the beam member 2 uses an oblique member 3 having an octagonal cross section, and a disc 7 is interposed in a portion where the pin 4 is inserted, so that the intersecting oblique members 3 and 3 are separated from each other. In this way, they are connected while maintaining a gap between them.
[0013]
Next, details of the diagonal member end portion and the diagonal member / column member connecting portion will be described with reference to FIGS. FIG. 3 is a perspective view showing a use state of a slide joint which is one of diagonal member / column member connecting portions, and FIG. 4 is a plan view thereof. The slide joint 6 projects two external support plates 8 and 8 and a central support plate 9 disposed in the inside in two directions orthogonal to the frame portion 7 through which the column material 1 is inserted. An end portion of the diagonal member 3 is provided with a cut portion 3b that can receive and reinforce the central support plate 9 while accommodating and reinforcing the filling member 3a. The end portions of the diagonal member are fastened using the bolts and nuts 10 passing through the external support plates 8 and 8, the central support plate 9, the diagonal member 3 and the filling member 3a.
[0014]
In addition, although the said description is about a slide joint, three support plates are similarly provided also about an edge part joint.
[0015]
【The invention's effect】
As described above, the folding tent of the present invention has an octagonal cross section of the diagonal member, and the interval between the intersecting diagonal members is widened and it is difficult to sandwich the awning. In addition, there is no risk of the fabric being damaged because it spreads even if it is sandwiched. Also with accommodating the filling member having a cut portion obliquely member end, the connecting member provided with three support plates, play is reduced between the coupling member and the diagonal member, stably the beam members It can be supported and is strong and less likely to cause rattling.
