Description

Pole assembly of tent frame

The present invention relates to a pole assembly of a tent frame, and more particularly to a pole assembly of a tent frame such that a portion of the joint connecting the poles to each other can be inserted into at least one pole.

Representative types of tent structures can be divided into dome type and cabin type. Such a tent structure is usually formed by a frame made of a joint connecting a plurality of poles and poles to each other, and a connecting means connecting the tents and poles.

Poles generally serve to maintain the shape of a prefabricated tent, and poles of various shapes and materials are used depending on the purpose of the tent. The pole may also be used as a support for installing temporary structures other than tents. The connection means may be composed of a loop or a hook connecting the tent with a pocket or pole formed in the tent so that the pole is inserted according to the purpose of the tent.

1 is an exploded perspective view showing a part of a pole assembly of a conventional tent frame.

2 is a longitudinal cross-sectional view taken in a state where a conventional pole assembly is connected.

The conventional pole assembly 1 consists of an upper pole 3, a lower pole 5 and a joint 7 connecting the upper pole 3 and the lower pole 5 as shown in FIGS. 1 and 2. .

In the above configuration, the upper pole 3 is a straight pole inserted into the pocket of the tent, and the lower pole 5 consists of a bent pole larger than the diameter of the upper pole 3. The upper pole (3) is made of FRP (Fiber Reinforced Plastics) material and the wall thickness of the pipe-type pole, the lower pole (5) is made of aluminum material, the thickness of the wall-type pipe pole.

As such, the upper pole 3 and the lower pole 5 are different in diameter from each other, and in particular, the lower pole 5 is made of an aluminum material having a large diameter. The reason is that the lower part of the tent is more affected than the upper part of the tent when a person is active inside the tent, and also to stably support the upper tent.

On the other hand, the joint (7) is bent in a gentle mountain shape, the bent portion is formed with a hole (8) into which a string, a ring, etc. can be fitted to fix the tent. In addition, both sides of the joint 7 include an insertion hole 7a into which the upper pole 3 and the lower pole 5 are inserted, and a locking step 7b formed on the inner circumferential surface of the insertion hole 7a. The joint 7 is molded by molding as a plastic material.

The pole assembly of a conventional tent frame made of such a configuration has the following problems.

First, the upper pole and the lower pole are respectively inserted into the insertion hole of the joint, so that when the external force is applied through the upper pole and the lower pole, the bending portion of the joint is broken or the upper pole is caused by the force to bend the upper pole and the lower pole. This break or cracks may occur in the joint portion into which the upper and lower poles are inserted and lose their function.

Second, because the pole assembly of the tent frame must be assembled in a state separated from each other, if the assembly is inexperienced, the assembly work is delayed, there is a high risk of loss because it must be stored in a separated state.

Third, the joint hole diameter of the joint should be at least equal to the diameter of the lower pole so that the outer circumferential surfaces of the upper pole and the lower pole are inserted into the insertion hole of the joint, so that the cross-sectional area of the joint is larger than the length of the upper pole and the lower pole inserted. As the length becomes longer, it becomes bulky and heavy, which increases the manufacturing cost due to the increase in material cost, thereby reducing the price competitiveness.

It is an object of the present invention to provide a pole assembly of a tent frame in which a part of a joint is inserted into an interior of at least one pole.

The present invention for achieving the above object is a joint 17 consisting of a receiving portion (17a) formed inside and the insertion portion (17b) formed on the outside; A first pawl 13 having an insertion portion 13a formed to be inserted into the receiving portion 17a of the joint 17; A pole assembly of a tent frame including a second pawl 15 having a receiving portion 15b formed therein to receive the insertion portion 17b of the joint 17.

In the above-described configuration, a locking jaw 17c is formed at one side of the receiving portion 17a of the joint 17, and a protruding jaw 17d is formed at one side of the insertion portion 17b of the joint 17. Is done.

In addition, the receiving portion 17a of the joint 17 is formed to have a predetermined length so as to overlap each other when the first pole 13 and the second pole 15 are connected.

On the other hand, when either one of the first pole 13 or the second pole (1) is a bent pole it is preferable that the ring 16 is formed in the bent portion of the bent pole.

In addition, the first pole 13, the second pole 15 and the joint 17 may be connected by an elastic line 19 installed therein to prevent loss of the pole assembly.
