BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pillar structure for an assembled tent.

[0002]

2. Description of the Related Art Conventionally, tents used in athletic meetings, gatherings, etc. have been constructed with roof-shaped columns, tent sheets that cover the roof of the columns, ropes that prevent the columns from falling, and ropes that are driven into the soil. It is composed of a stock that locks one end. The tent columns are made up of many pipes such as column pipes, ridge pipes, girder pipes, beam pipes, and gas pipes. Firstly, they are lightweight and easy to carry, and secondly, they are easy to assemble and store. Thirdly, it is required to have the required strength. For this reason, the actual break 56-62
As shown in Japanese Patent No. 33, etc., it is known that each pipe is divided into short pieces, which are connected to each other when assembling a tent.

[0003]

However, in the above-mentioned conventional strut structure of the tent, the ridge pipe and the gas pipe are directly connected, and the girder pipe, the beam pipe, the gas pipe and the pillar pipe are directly connected. , The joint of these pipes, that is, the joint strength between the roof corner and the eaves corner is weak, and when a large force is applied from above or from the side,
There was a problem that the entire tent was twisted and distorted or tilted, or the joint was damaged.

Therefore, the present invention has been made in view of the above-mentioned conventional problems, and its purpose is to provide excellent portability, assembling workability, and storability, and to provide a roof corner portion. The bond strength at the corner of the eaves is great,
Another object of the present invention is to provide a strut structure for a tent, which can prevent the joint from being twisted and damaged.

[0005]

In order to achieve the above object, the present invention provides a strut structure for a tent, which is constructed by detachably connecting a ridge pipe, a girder pipe, a beam pipe, a gas pipe, a pillar pipe, and the like. The pillar pipe is an outer pipe,
An inner pipe that is telescopically inserted into an outer pipe, and at least the ridge pipe, girder pipe, and beam pipe are each composed of a plurality of divided pipes that are divided in the longitudinal direction, and a joint portion of these divided pipes. Is a sleeve whose one end is crimped and fixed to the joint of one of the split pipes, a stopper pin which is normally projected to the outside by a gush-in incorporated inside the other end of this sleeve, and the joint of the other split pipe. A ridge corner block, which is formed with a fitting hole into which the stopper pin is fitted, and where the ridge pipe and the gas pipe are joined, is provided with the ridge corner block. The eaves corner block to which these pipes are joined is provided at the joint part of the pipe and the pillar pipe, and the ridge corner block is a gas pipe It is composed of a cylinder part for a palm pipe to which one end fits, and a joint pipe for a ridge pipe to which one end of the ridge pipe fits, and is incorporated inside the palm pipe on the circumferential surface of the cylinder part for the palm pipe. A fitting hole into which the stopper pin projecting to the outside is fitted is formed by the spring, and a stopper pin projecting to the outside by the spring and fitted into the fitting hole of the ridge pipe is formed inside the joint pipe for the ridge pipe. The eaves corner block is installed, the other end of the gas pipe, the one end of the beam pipe and the upper end of the pillar pipe are fitted into the gas pipe pipe cylindrical portion,
A cylindrical portion for a beam pipe and a cylindrical portion for a pillar pipe, and a joint pipe for a girder pipe to which one end of the girder pipe fits, the cylindrical portion for a gas pipe, the cylindrical portion for a beam pipe, and the cylindrical pipe for a column pipe. Fitting holes into which the stopper pins projected to the outside are fitted are formed on the peripheral surface of the portion by fitting in the respective pipes, and inside the joint pipe for eaves pipe is outwardly opened by a spring. A stopper pin that projects and fits into the fitting hole of the girder pipe is incorporated.

[0006]

In the present invention, the ridge pipe, girder pipe, and beam pipe are divided into short pieces to facilitate transportation and storage. Similarly, the pillar pipes can also be expanded and contracted to facilitate transportation and storage. The ridge corner block and the eaves corner block increase the joint strength of the pipes at the roof corner and the eaves corner.
