DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

According to a preferred embodiment of the present invention, the folding type article 100 including a chair, a bed, a tent, and the like is connected to the elastic string frame 3 by the connection assembly member 1 and the elastic string 2, The elastic string 2 is connected to one end of the elastic string 2 so as to form a leg or a support frame of the elastic string 2, A coupling assembly member (1) constituting a plurality of coupling grooves (10) so as to be capable of being selectively displaced and coupled; One side of which is connected to the connection assembly member 1 or is provided so as to be able to pass by and the other side of which is connected to the elastic string frame 3 so that the elastic string frame 3 is elastically operated (2); And an elastic string frame (3) coupled to one side of the elastic string (2) and configured to be elastically fitted or detachable to the connection assembly member (1) A frame displacement device is provided.

At this time, the foldable article 100 represents various folding products such as a chair, a bed, and a tent which are folded.

Next, the connection assembly member 1 can be manufactured by various methods such as molding using a synthetic resin, metal casting using a die casting or a mold, and a plurality of coupling grooves (not shown) for fitting the elastic string frame 3 10 through the coupling holes 12 smaller than the coupling grooves 10 so as to be able to engage or pass the elastic ropes 2 through the inner bottom. The plurality of engaging grooves 10 are formed with an opening 14 smaller than the diameter of the engaging groove 10 so that the elastic string 2 is inserted into any one of the engaging grooves 10 The foldable article 100 is constructed to be movable through the openings 14. The foldable article 100 may have various configurations depending on the number of the elastic string frames 3 required and the installation position thereof, A separate stationary frame 5 is also provided with a portion for fixed installation.

The elastic string 2 may utilize various types of strings such as a rubber string or a spring having excellent elasticity and the elastic string frame 3 may be elastically fitted to the coupling groove 10 of the connection assembly member 1 When the elastic string frame 3 is separated from the coupling groove 10 and the elastic string frame 3 is to be folded, the elastic string 2 itself is flexible and freely foldable. The elastic string frame 3 is not completely separated from the connection assembly member 1 but is constructed so that the operation can be performed while maintaining the mutually connected state.

Next, the elastic string frame 3 is manufactured by using a hollow metal pipe or a synthetic resin pipe having excellent rigidity. The elastic string frame 3 is made of a synthetic resin pipe, (30) are fixedly coupled to each other. At this time, when the foldable article 100 is constructed as a foldable chair, the foldable article 100 may be adopted as a role part that is positioned below the connection and assembly member 1 except for the central fixed frame 5, , And can be used as a role part which is positioned on the upper part of the connection and assembling member 1 and is combined with the seat and the thus combined seat is supported and fixed. When the folding type bed 100 is constructed as the foldable type article 100, the elastic string frames 3 are assembled upwardly to the connecting assembly member 1 fixed to both sides of the fixed frame 5, Role can be performed simultaneously.

Next, the stationary frame 5 is a frame which is positioned at the center when the foldable article 100 is constructed as a foldable chair, and is a frame fixed to the various connection and assembly members 1. The foldable article 100 is foldable, In the case of constructing a bed, the fixing frame 5 between the connection assembly members 1 located on both sides thereof represents a fixedly installed frame.

Reference numeral 6 denotes a chair seat, and reference numeral 7 denotes a bed sheet to be joined together with the supporting bar 70. [

Thus, the present invention, which is configured as described above, is operated as follows.

First, when the elastic string frame 3 is applied to the legs from the lower part of the folding chair 100 as the folding type article 100, the engagement groove 10 is formed at the most forward position among the plurality of engagement grooves 10 formed in the connection assembly member 1, When the elastic string frame 3 is engaged with the elastic string frame 10, the leg height of the elastic string frame 3 is at the highest position, and among the plurality of engagement grooves 10 formed in the connection assembly member 1, The leg height of the elastic string frame 3 is at the lowest position when the elastic string frame 3 is engaged with the coupling groove 10 located at the position of the seat 1. However, It is possible to have the advantage of being able to use the balance with stability while maintaining the posture.

Next, when the elastic string frame 3 is applied to the structure for supporting the chair seat 6 at the top of the folding chair as the foldable article 100, the plurality of engagement grooves 10 formed in the connection assembly member 1, When the elastic string frame 3 is engaged with the coupling groove 10 located at the innermost position of the elastic string frame 3, the width of the elastic string frame 3 is at the narrowest position, It is possible to maintain a comfortable feeling as a form of wrapping the user's body in a low state although the chair seat 6 is not stretched tightly when the chair seat 6 is joined to the connecting member 1, When the elastic string frame 3 is coupled to the coupling groove 10 located at the outermost position of the groove 10, the width of the elastic string frame 3 is enlarged so that the chair seat 6 is unfolded to a high state While the elasticity is maintained, It is able to have the features that are available for use.

Next, when the foldable article 100 is used for the purpose of adjusting the height of the leg while supporting the bed sheet 7 at the upper part of the foldable bed, among the plurality of engagement grooves 10 formed in the connection assembly member 1 When the elastic string frame 3 is engaged with the coupling groove 10 located at the innermost position, the width of the elastic string frame 3 is at the narrowest position in the both elastic string frames 3, When the supporting bar 70 is engaged and the bed sheet 7 is unfolded, the bed sheet 7 is not stretched very tightly, but the user can use the bed sheet 7 while maintaining a comfortable feeling in a state where the height of the leg is relatively high, When the elastic string frame 3 is coupled to the coupling groove 10 located at the outermost position among the plurality of the coupling grooves 10 formed in the assembly member 1, the width of both elastic string frames 3 is widened, (7) is unfolded tightly But able to use the elasticity in a state that a little more to have at a relatively low height of the legs the user is able to have the features that are available for use.

As described above, according to the present invention, in the elastic string frame 3 used in the foldable article 100 including the chair and the bed, the installation position and the installation angle of the elastic string frame 3 can be changed It is possible to adjust the height of the folding type article 100 by adjusting the width of the folding type article 100 or to use various folding articles 100 such as a chair and a bed, ) Can be conveniently used for general purposes.
