The leg pipe bodies are formed by being drawn to form a curved shape by bending at a relevant angle, and their height displacement varies according to the angle of being engaged with the engagement holes of the hub members. Accordingly, the angle can be more diversely controlled to meet the user environment thanks to the engagement angle of the leg pipe bodies engaged with the engagement holes of the hub members. In addition, the difficulties can be addressed such as the smaller volume of the hub members for the engagement holes for controlling the angle and the insertion of the pipe bodies into other holes by being taken completely out from the existing holes for controlling the angle.

Description

Frames for folding outdoor items

The present invention relates to a frame of a folding outdoor article, and more particularly, by combining a plurality of tubular bodies connected to each other by an elastic cord to a hub member, the hub member in the frame of the folding outdoor article forming a folding bed, chair, table, etc. It relates to a frame of a foldable outdoor article that allows the height and inclination of the foldable article to be displaced by varying the joining angle of the bridge body toward the ground while being coupled to the joint hole of the foldable article.

In general, in the case of a folding outdoor article (furniture) including a conventional folding chair, a folding table, etc. have been developed and used in various forms.

As an example of such a folding outdoor article, "portable chair" of Korean Patent Registration No. 10-1176740 and "folding furniture" of US Patent No. 5,709,428 have been disclosed.

In the conventional folding outdoor article, the supporting members on both sides are fixed to each other with a horizontal frame, and the supporting members on both sides are configured with frames in up, down, front, and rear directions, respectively, but the lower positions of these frames serve as legs. The lower frame is installed and the upper frame that is installed to fix the seat is installed at the upper position, and the upper frame located at the upper part of these frames is configured to be foldable by combining the seat for sitting. have

In common with these prior art, a plurality of upper and lower frames, which are coupled to each other in a separable manner with the support members on both sides, are composed of a cylindrical pipe shape and are simply structured to be coupled to each other with the support member together with an elastic cord. , especially when the user sits on the seat and a load or external force is applied to these frames, or when the frame and the supporting member are not properly combined in the right position in the process of combining them, especially when the lower frame and the floor are in contact with each other. Because the position is maintained unstable, the posture of the seated user is also unstable, which not only causes inconvenience in use, but also causes a safety accident due to the chair falling over.

And although the prior art says that it is convenient to store or transport the article by folding it after use, in actual use, the height of the foldable article cannot be adjusted, so once assembled, it must be used just like the existing fixed article. There is a downside to

In addition, even in the case of a seat plate or bed sheet in the form of a seat installed on the upper part of these frames, the width cannot be variably used narrowly or widely, and once assembled, it has to be used as it is, just like the existing fixed article. There is a problem in that you have to take the inconvenience because there is no way to pull them tight together or to adjust them.

In order to solve this problem, Korean Patent Registration No. 10-1917731 (November 6, 2018) has proposed "a device for displacing an elastic cord frame of a foldable article".
