[Prior art]

 Generally, tents are equipped with tarpaulins and multiple tent posts to allow the user to stay on camping or in the field temporarily. After assembling a number of tent posts together to form a certain shape, a tent is constructed by putting a waterproof cloth on them.

[0003] The tent support is a framework for forming an inner space of the tent, and is usually formed in a cylindrical pipe shape. As shown in FIG. 4, a rubber band or elastic string 20 having excellent elasticity is provided in the inner space of the tent post 10. Specifically, at one end of the tent post 40, a contracted tube portion 41 whose outer diameter is smaller than the inner diameter of the other portion of the tent post 40 is formed. On the other hand, an expanded tube portion 32 into which the contracted tube portion 41 can be inserted is formed at the other end of the other tent post 30 to be connected. The contracted tube portion 41 is inserted into the expanded tube portion 32 of another tent post 30, and the tent posts 30, 40 are connected to each other.

When the tent posts 30, 40 are aligned in a line, the tent posts 30, 40 are pulled from each other by the elastic force of the elastic cord 20, so that the tent posts 30, 40 are easily connected to each other. be able to.

In such a connection structure of the tent strut, since the expanded tube portion 32 and the contracted tube portion 41 have a smaller thickness than other portions, there is a high possibility that the tube is bent and damaged. FIG. 6 is a cross-sectional view of a connected state of a conventional tension support. As shown in FIG. 6, a reinforcing rod 43 having an outer shape corresponding to the internal shape of the start portion 44 is provided inside the start portion 44 of the contracted tube portion 41 to reinforce the expanded tube portion 32 and the contracted tube portion 41. The installation structure has been developed. The reinforcing rod 43 reinforces the start portion 44 of the contracted tube portion 41 to prevent the start portion 44 of the contracted tube portion 41 from being damaged when connecting the tent support.

On the other hand, a ring-shaped stopper 33 can be attached to the expanded portion 32 of the other tent post 30 to be connected in order to restrict the entrance of the contracted tube portion 41 of the inserted tent post 40. .

However, as shown in FIG. 6, in the connection structure of the tent columns, when the tent columns 30, 40 aligned in a line are pulled together by the elastic force of the elastic cord 20, the contraction of the tent columns 40 is performed. The section 41 and the expanded section 32 of the tent post 30 collide with each other. Usually, the tent post is made of aluminum material and has a small thickness, which causes a problem that the end is easily damaged due to the collision of the end.

[0008]

 In order to achieve the above object, the tent post according to the present invention has a constricted portion of a predetermined length which is inserted into the inside of the tent post at one end, and is provided outside the start portion of the constricted portion. Is characterized by having a stopper for limiting the insertion length of the contraction tube.

[0010] Preferably, the stopper is formed in a ring shape having a hole formed in the center.

Further, the tent post according to the present invention includes a finishing member that, when connecting the tent post, performs a cushioning action against an end of another tent post connected to the contracted tube portion. It is provided at the end of the part.

[0012] The finishing member includes an outer surface of the streamline type convex portion and an insertion portion inserted into the contracted tube portion of the tent post, and has a small central portion through which an elastic cord passing through the inside of the tent post penetrates. It is preferable to configure so as to form a through hole.

[0013] Inside the start portion of the contracted tube portion of the tent post according to the present invention, a reinforcing rod having an outer shape corresponding to the internal shape of the start portion and located inside the start portion and reinforcing the start portion is provided. Can also be installed.

In addition, the connecting structure of the tent post according to the present invention has a stopper for restricting the insertion length of the contracted tube outside the start portion of the contracted tube having a predetermined length at one end of the tent post. The tubing is inserted into another tent post to be connected, and the tent posts on both sides are connected to each other.

[0015]

[Embodiment of the invention]

 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a perspective view of a connecting portion of an embodiment of a tent support according to the present invention, and FIG. 2 is a cross-sectional view of the connected tent support. As shown in the figure, at one end of the tent post 60, a contracted tube portion 61 having a smaller outer diameter than other portions of the tent post is provided at a predetermined length. In the embodiment shown in the figure, an expanded portion is not formed at the end of the tent post 50 to be connected, but an expanded portion having an inner diameter larger than the outer diameter of the contracted portion 61 may be formed.

In the present invention, a ring-shaped stopper 70 is mounted on the outside of the contracted tube portion 61 of the tent post 60. When the constricted portion 61 is inserted into the end of another tent post 50, the end of the other tent post 50 can be fitted to the start portion 62 of the constricted portion 61, but the other tent If the end of the strut 50 is firmly fitted to the start portion 62 of the constricted tube portion 61, not only the outside of the start portion 62 may be damaged, but also it may be difficult to separate the connected tent struts 50, 60 from each other. There is. In the present invention, when the contracted tube portion 61 is inserted into the end portion of the other tent post 50 for a predetermined length or more, the end portion of the other tent post 50 comes into contact with the stopper 70. The tent will not be able to be inserted more than a predetermined distance into the column 50. Therefore, it is possible to prevent the end portions of the other tent posts 50 from being firmly fitted to the start portions 62 of the contracted tube portions 61 and making it difficult to separate the tent posts 50 and 60. The inner shape of the stopper 70 matches the outer shape of the contracted tube portion 61 and the start portion 62 of the contracted tube portion 61. FIG. 5a shows the stopper 70, and FIG. 5b shows its cross section.

The end portion of the contracted tube portion 61 of the tent post 60 of the present invention is provided with a finishing member 90. As shown in FIG. 2, the finishing member 90 is composed of an outer surface 92 of a streamline type convex portion and an insertion portion 93 inserted into the constricted tube portion 61 of the tent post 60. A small through-hole 91 through which the elastic cord 20 penetrating the inside is formed. The material of the finishing member 90 is not particularly limited, but is preferably made of a soft material. The through hole 91 is limited to a size that allows the elastic cord 20 to penetrate. FIG. 3 is a cross-sectional view showing a connection state of the tent posts 50 and 60 of the present invention provided with a finishing member 90 of another shape. FIG. 4 is a cross-sectional view showing a connection state of the tent posts 50 and 60 of the present invention provided with a finishing member 90 of another shape. In the embodiment shown in FIG. 4, the tent post 50 connected to the tent post 60 has an expanded portion whose inner diameter is larger than the outer diameter of the contracted portion 61 of the tent post 60.

The elastic cords 20 are penetrated inside the tent posts 50, 60. When the tent posts 50, 60 are arranged in a line, the elasticity of the elastic cords 20 pulls the tent posts 50, 60 together. However, when the tent posts 50 and 60 are pulled from each other, there is a possibility that the ends of the tent posts 50 and 60 may collide with each other. The finishing member 90 provided at the end of the contracted tube portion 61 of the tent post 60 provides a buffering action when the ends of the tent posts 50 and 60 collide with each other. Accordingly, it is possible to prevent the ends of the tent posts 50 and 60 from directly colliding with each other and the ends of the tent posts are damaged.

Since the outer surface 92 of the finishing member 90 has a convex curve, when the end of the tent post 50 collides with the outer surface 92 of the finishing member 90, the tent post 60 of the tent post 60 follows the curve of the outer surface 92. The contracted tube portion 61 is smoothly inserted into the end of the tent post 50. Therefore, when the tent posts 50 and 60 are connected, the generation of noise due to the collision of the ends is also prevented.

Since the size of the through hole 91 is limited to a size that allows the elastic cord 20 to penetrate, when the tent posts 50 and 60 are connected, the position of the elastic cord 20 holds the center. As a result, the connected tent posts 50, 60 are easily aligned in a line.

As shown in FIGS. 2 and 3, in the case of the tent support according to the present invention, a reinforcing rod 80 for reinforcing the start portion 62 may be provided inside the start portion 62 of the contracted tube portion 61. it can. The reinforcing rod 80 has a ring shape with a predetermined thickness, and has an outer shape corresponding to the inner shape of the start portion 62 of the contraction portion 61. The reinforcing rod 80 is fitted inside the tent post 60 and is located at the start portion 62 of the constricted portion 61.

The tent posts 50 and 60 according to the present invention are connected to each other by the following structure. First, the stopper 70 is attached to the outside of the contracted tube portion 61 of the tent post 60. A reinforcing rod 80 is inserted and fixed inside the contracted tube portion 61. A finishing member 90 is provided at an end of the contracted tube portion 61 of the tent support 60.

When the tent posts 50, 60 are aligned in a straight line, the tent posts 50, 60 are pulled from each other by the elastic force of the elastic cord 20. When the end of the tent post 50 contacts the finishing member 90, the contracted tube portion 61 of the tent post 60 is smoothly inserted into the end of the tent post 50 along the streamlined outer surface 92 of the finishing member 90. The contracted tube portion 61 is inserted to a predetermined length, the end of the tent post 50 is stopped while contacting the stopper 70, and the connection between the tent posts 50 and 60 is completed.

[0024]

[Effect of the invention]

 As described above, according to the present invention, the finishing member 90 provided at the end of the contracted tube portion 61 of the tent post 60 performs a buffering action when the ends of the tent posts 50, 60 collide with each other. Therefore, it is possible to prevent the ends of the tent posts 50 and 60 from directly colliding with each other and breaking the damage of the ends of the tent posts.

Since the outer surface 92 of the finishing member 90 has a convex curve, when the end of the tent post 50 collides with the outer surface 92 of the finishing member 90, the tent post 60 moves along the curve of the outer surface 92. Is smoothly inserted into the end of the tent post 50. Therefore, when the tent posts 50 and 60 are connected, the generation of noise due to the collision of the ends can also be prevented.

A reinforcing rod 80 is provided inside the start portion 62 of the contracted tube portion 61 of the tent post 60 to reinforce the start portion 62. Therefore, even if an external force is applied and stress is concentrated on the start portion 62, the start portion 62 is prevented from being damaged by the reinforcing action of the reinforcing rod 80. Therefore, a strong connection between the tent posts 50 and 60 can be ensured.

Since the strength of the starting portion 62 is increased by the reinforcing action of the reinforcing rod 80, the length of the contracted tube portion 61 inserted into the end of the tent post can be reduced as compared with the conventional tent post. As a result, the weight of the tent post can be reduced.

In particular, since the stopper 70 is provided outside the constricted portion 61 to limit the insertion length of the constricted portion 61, the end of the tent post 50 is further extended to the start portion 62 of the constricted portion 61. Since the fitting is prevented, the connected tent posts can be easily separated, and the start portion 62 can be prevented from being damaged.

Although the tent support according to the present invention has been described above, the present invention is not limited to the tent support but can be applied to a cane or the like.
