Description

Connecting Structure of Tent Pole}

The present invention relates to the connection structure of the tent poles, and more particularly to the connection structure of the tent poles to overcome the fragility of the connection portion between the poles and poles forming the frame of the tent to maintain a solid coupling state.

In general, the tent is composed of a waterproof cloth and a plurality of poles so that the user can temporarily live in camping or outdoors to assemble these poles to form a tent of a certain type.

The tent pole is a frame for opening a tent to form a space therein, which is usually made in the form of a cylindrical pipe, and the elastic space is provided in the inner space of the pole, and connects a plurality of poles, A locking tip or a general tip is attached to the end of the pawl to be engaged.

That is, as shown in the accompanying drawings, Figure 1, one side of the pole (2) inserts only a portion of the connecting rod (4) having a certain length, the position, fixed to be in close contact with the inner surface using a separate adhesive or press during insertion The exposed portion of the connecting rod 4 is inserted into the other pole 6 so as to be connected to each other. By the way, when the strength to the connection portion is to be adjusted to reach a certain level, the outer diameter of the connecting rod (4) in the structural structure of the pole (2) can not be increased in the end to set the thickness of the connecting rod (4) to the most suitable The strength is derived and produced.

Therefore, the number of poles as described above, if the poles 2 to form a short length for one pole in the poles of the same overall length in order to downsize the length of the tent pole 1 for the user to easily carry Since the entire length of the connecting rod 4 to be attached and fixed according to the need arises, a problem occurs that results in an increase in the weight of the entire tent pole 1 due to the increased pole and the connecting rod.

On the other hand, if the strength between the pole and the connecting rod is not maintained, that is, the strength of the connecting rod 4 becomes relatively weaker than that of the poles 2 and 6, as shown in FIG. The phenomenon in which the connecting rod 4 inserted into the poles 2 and 6 is bent and broken occurs, while the strength of the poles 2 and 6 is increased by the connecting rod 4 as shown in FIG. 3. When the strength is weaker than that of the poles (2) and (6), one of the bends and breakage occurs.

In addition, when using an adhesive or a separate position fixing press to position and fix the connecting rod 4 on the inner surface of the pole 2, the former may exclude the case that the connecting rod 4 is separated due to poor adhesion. The latter causes another problem, such as breaking the connection part of the poles 2 and 6 when the pressing pressure of the press is changed.

Meanwhile, in order to solve the problems of weight and fragility of the pole connecting rod as described above, as shown in FIG. A method of inserting and fixing 10) into the interior of the pole 12 to be combined has been proposed, in which case the user has to reduce the length of the tent pole 1 so that the user can carry it easily. In the case of forming a short length for each node of the, as shown in Figure 1 according to the number of poles, separately attached, fixed connecting rods 4 are removed, the length of the shaft tube portion 10 is connected to each other overlapping Is reduced by half compared to the length of the connecting rod 4, and as a result, the weight is reduced relative to the connecting rod 4 can be made lightweight. However, in order to increase the strength in order to maintain the strength of the shaft portion 10 at an appropriate strength as described above, it is difficult to variably control the thickness as in the connecting table 4, and thus the inertia of the shaft portion 10 portion. Moment is smaller than the moment of inertia of the pole 8, the shaft tube portion 10 is always broken first.

The present invention is devised to solve the conventional problems as described above, it is designed to provide a tent pole connection structure that can withstand the external force applied at the connection portion of the pole and the pole to prevent the damage of the pole in advance. There is a purpose.

The present invention for achieving the above object is a common tent pole, the expansion and condensed pawls are coupled to each other, the stopper is inserted, fixed inside the expansion pipe formed on one side of each pole, the shaft formed on the other side Inside the part is characterized in that the reinforcing rod inserted, fixed.

The stopper is formed in a ring shape, the reinforcing rod is formed in a circular portion on the front, and a conical portion having an inclined surface on the back, characterized in that formed.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 6 is a cross-sectional view of the combination of the present invention, Figure 7 is a perspective view of the stopper is inserted into the pole of the present invention, Figure 8 is a perspective view of the reinforcement is inserted into the pole of the present invention.

As shown in the present invention, in the conventional tent poles, the expansion and condensed poles 20 are coupled to each other, and the stopper 30 is inserted into the expansion part 21 formed at one side of each pole 20. It is a structure in which the reinforcing table 40 is inserted and fixed inside the shaft pipe part 22 formed at the other side.

Here, the stopper 30 is formed in a ring shape while the hole 31 is formed in the center position, the reinforcing rod 40 also forms a circular portion 42 on the front side of the hole 41 is formed in the center thereof, The rear surface has a structure formed integrally with the conical portion 44 having an inclined surface 43.

In the figure, reference numeral 20 'is a pole corresponding to the pole 20 according to the present invention, and has the same structure as the pole 20.

The present invention configured as described above first inserts and fixes the stopper 30 and the reinforcing table 40 in the expansion pipe portion 21 and the shaft pipe portion 22 of the pole 20. In this state, when one end of another pole 20 'having the same structure is inserted as shown in FIG. 6, the stopper 30 and the pole 20' that are inserted and fixed inside the other pole 20 'are fixed. Ends of the shaft tube portion 22 of the pole 20 corresponding to the stop and come into contact with each other to form a coupling between the poles.

Here, when an external force acts on the coupling portion between the pawls 20, that is, the shaft tube portion 22 and the expansion tube portion 21 of the other pole 20, the reinforcing rod 40 is positioned at the position of the shaft tube portion 22. There is a built-in to prevent the pole from breaking.

In addition, compared to the related art, the length of the shaft pipe portion 22 inserted into the expansion pipe portion 21 of the correspondingly coupled pole 20 'can be used to shorten the weight of the same number of polo tents. Can be achieved.

Thus, the present invention does not use all of the problems of the conventional tent pole, that is, the entire length of the connecting rod for connecting the pole and the pole, and about half of the shaft portion is used, so that the weight of the pole can be achieved. It is a very useful design that has the effect of being able to overcome the weakness of the connection part between poles through a reinforcement, so that it can maintain a strong pole.
