Description

  The present invention relates to a connection structure of a tent frame of a simple assembly type and a tent curtain material covering the tent frame, which is easy to assemble and disassemble, which is used for temporary assembly at indoor or outdoor gatherings, events, events, etc. Regarding the tent used.

  Generally, when constructing a temporary tent used for gatherings, events, events, etc., a plurality of long transverse members and pillars are connected by a joint 4 to form a tent frame, and the tent frame is formed. Tent curtain materials such as cloth sheets and vinyl sheets were stretched.

  Conventionally, in a temporary tent, although not shown, a string or rope is passed through an eyelet metal fitting provided at an end of the tent curtain material, and the string or rope is wound around a horizontal member of a tent frame and fixed. As a result, the tent curtain material has been stretched over the tent frame.

  By the way, in a tent in which a tent curtain is stretched on a tent frame with a string or a rope, a plurality of strings or ropes must be wound around a horizontal member of the tent frame and fixed during construction. There is a problem that a complicated operation is required, and a complicated operation is also required when removing the tent curtain material.

  On the other hand, as tents capable of connecting a tent frame and a tent curtain material without using a cord or a rope, those having structures described in Patent Documents 1 to 4, for example, are known.

  That is, in the tents described in Patent Documents 1 and 2, as shown in FIG. 10A, an insertion groove 21 is formed in a frame material 20 or the like forming a tent frame, and a tent curtain material 22 is formed in the insertion groove 21. By inserting the bulging portion 23 provided at the end of the tent, the tent curtain 22 is stretched over the tent frame.

  Further, as shown in FIG. 10B, the tents described in Patent Literatures 3 and 4 are sheet-stretched on a square pipe member 24 forming a tent frame by rail mounting members 25 (comprising bolts 25a and nuts 25b). By attaching a retaining rail 29 provided on the ear of a long sheet 28 (tent material for a tent) to a guide groove 27 formed in the sheet stretching rail 26. The seat 28 (tent curtain material) is stretched over the tent frame.

However, in the tents described in Patent Documents 1 to 4, the bulging portion 23 of the tent curtain material 22 and the retaining portion 29 of the long sheet 28 are both formed in a long shape, and the bulging portion is formed. 23 and the retaining portion 29 are provided with solid ropes, so that the bulging portion 23 of the tent curtain material 22 and the retaining portion 29 of the long sheet 28 are used for the end of the frame material 20 and the sheet stretching. It must be inserted into the insertion groove 21 and the guide groove 27 sequentially from the end of the rail 26, and the frictional resistance between the bulging portion 23 and the insertion groove 21 and the frictional resistance between the retaining portion 29 and the guide groove 27 are reduced. It becomes considerably large and it becomes difficult to insert the bulging portion 23 and the retaining portion 29 into the insertion groove 21 and the guide groove 27, and it takes time to stretch the tent curtain material 22 and the long sheet 28 into the tent frame. There is a problem.
In particular, the above problem becomes more remarkable as the length of the frame member 20, the sheet stretching rail 26, the bulging portion 23 of the tent curtain member 22, and the retaining portion 29 of the long sheet 28 become longer. become.
