[Prior art and problems to be solved by the invention]

  These days, holidays often include outdoor travel, barbecues, and outdoor sports. It often happens that a table or chair is needed at that time. In that application The foldable design is used in consideration of convenience and portability. Figure 10 and 11 are diagrams showing the design of a conventional folding table (1). Ba -(11) is fixed to the pin joint pedestal (12) at the upper end. Pin joint base (1 2) The movable sleeve located outside the bar (11) in the lower position is It is possible to move along 1). Expand the folding table (1) to move The sleeve (13) is linked by the folding bar (14) and the pin joint pedestal (12) Then, it goes up from the lower end of the bar (11) to the middle part of the bar (11). This allows you to All mechanisms are fully deployed. In this case, the lower end of the bar (11) is fixed However, the position of the center of gravity of the pin joint pedestal (12) is also applied. to this Therefore, the following drawbacks occur.

[0003]   First, there is no support for fixing the legs of the folding table (1), so the weight of the table My heart becomes unstable. Then, things placed on such a table become unstable It is very inconvenient to fall down.

[0004]   Second, the conventional folding table (1), whose center of gravity is unstable, is lightweight considering portability. Since it is made of various materials, it is easily disassembled when shocked and placed on it. The things I used to spill with me. User is in a bad mood due to poor usability It's no wonder it becomes.

[0005]   In order to solve these problems, the present inventor has made many years of making table chairs. The experience of manufacturing and design led to the present invention after trial and error trial production.

[0006]   The present invention does not wobble during deployment and use, and can be easily disassembled even if it strikes. Not intended to provide a stable table and chair leg stretch structure.

[0007]

[Means for Solving the Problems]

  In order to achieve this object, the elastic structure of the legs of the table and chair according to claim 1. Consists of one column, one upper bar sleeve and one sleeve Through the through hole in the upper end of the sleeve to allow operation The end is plugged in, the stanchion is inserted into the upper bar sleeve and its upper end Align the through hole on the upper bar sleeve with the through hole provided on the Is fixed, and the upper end of the column is projected from the upper end of the upper bar sleeve. One end of the folding bar is fixed to the outside of the upper bar sleeve and the other end is fixed. It is fixed to the bottom of the sleeve and when folded, the movement of the struts Being restricted to leaves, the sleeve should be aligned with the movement of the stanchions. When moving down and unfolding, the sleeve moves up and the strut moves It slides downward along the inside of the through hole in conjunction with.   The elastic structure of the legs of the table and the chair according to claim 2 is the table according to claim 1. In a retractable structure of the bull and chair legs, the pillar is attached to the upper end of the sleeve at the lower end. And the struts limit the upper bar sleeve when folding, The sleeve is moved downward so as to match the movement of the column.   The elastic structure of the legs of the table and the chair according to claim 3 is the table according to claim 1. In a bull and chair leg telescopic structure, the upper bar sleeve is above the column. Fixed to the end face, the top of the strut is adjacent along the upper edge of the upper bar sleeve. Is what you are doing.   The elastic structure of the legs of the table and the chair according to claim 4 is the table according to claim 1. In the retractable structure of the bull and the legs of the chair, the lower end of the column is the lower sleeve bar. The upper end is inserted into the upper sleeve and is folded when folded. The upper sleeve moves upward without expanding from the restraint of the strut and expands. At this time, the top end of the support column fits into the upper end of the upper sleeve.

[Embodiment of device]

  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Of course, The following embodiments merely show the preferred embodiments of the present invention, and the technical scope of the present invention is as follows. The present invention is not limited to the following examples, and the following examples are the same as the present invention. Various improvements and modifications are possible without departing from the spirit of the invention.

[0009]   As shown in FIGS. 1 to 4, the present invention mainly includes one support (21) and one support (21). It consists of two upper bar sleeves (22) and one sleeve (23). Therefore, the operation can be performed in the through hole (231) provided at the upper end of the sleeve (23). The lower end of the column (21) is inserted so that Also, the column (22) is an upper bar. -A through hole (21) inserted in the sleeve (22) and provided at the upper end of the column (21) 1) Align the through hole (221) in the upper bar sleeve (22) with It is fixed with a nut (24). In this case, the upper end of the column (21) is the upper barthree. It is fixed so that it protrudes from the top of the knob. One end of the folding bar (3) is the upper berth It is fixed to the outside of the leave (22) and the other end is fixed to the bottom of the sleeve (23). As shown in FIG. 5, when folded, the movement of the post (21) is such that the upper bar sleeve (2 2), so the sleeve (23) should match the movement of the column (21). And move down. Further, when unfolding, the sleeve (23) moves upward. The pillar (21) is slid downward along the through hole (231) in conjunction with this. To The center of gravity of the mechanism rests on the lower edge of the sleeve (23). With the above structure, The following merits are obtained.

[0010]   First, since the sleeve (23) is arranged at the lower end of the elastic structure (2), When unfolding the tatami table, the sleeve (23) and the upper bar sleeve (22 ) Stabilizes the entire structure due to the restraint force between them, and there is a concern that something will spill when placed on it. Disappears.

[0011]   Second, the center of gravity of the structure according to the present invention is very stable, so carelessly folding the table The table is easily dismantled or placed on top of it even if it hits a bull No more worrying about spilling easily.

[0012]   In another preferred embodiment (1) of the present invention shown in FIG. 6, the sleeve (23) is A column (21) is inserted into the upper end from the lower end. When folding, the column (21) The movement of the upper bar sleeve (22) limits the sleeve (23) to the strut ( 21) Move downward so as to match the operation of. Furthermore, when deploying, The sleeve (23) moves upward along the column (21).

[0013]   In another preferred embodiment (2) of the present invention shown in FIG. 7, the upper bar sleeve ( 22) is fixed to the upper end surface of the column (21), and the top of the column (21) is the upper berth. Adjacent along the upper edge of the leaves (22).

[0014]   In another preferred embodiment (three) of the present invention shown in FIG. 8, the lower end of the column (52) Is connected and fixed to the lower sleeve bar (53), the upper end is the upper sleeve (51) Inserted inside. In this case, when folding the upper sleeve (51), Move upward without leaving the restraint of 2). Furthermore, when deploying, ) Fits on top of upper sleeve (51).

[0015]   Yet another preferred embodiment of the present invention is a folding chair (4) shown in FIG. ). The original known (prior art) folding structure (5) of the folding chair is As shown in FIG. 12, the lower end of the column (52) is connected to the lower sleeve bar (53). It is tied and fixed and the upper end is inserted into the upper sleeve (51). In this case, the exhibition When open, the top ends of the struts (52) project from the top end of the upper sleeve (51). Furthermore, when folding, the upper sleeve (51) should be separated from the restraint of the support column (52). Without moving, and slide down along the stanchions (52) when unfolding To do. The above structure is developed from the preferred embodiment (3) of the present invention.

[0016]   It should be noted that it is clear from the description of the above-mentioned embodiment, but just in case so as not to cause doubt. To explain, the present invention is a stretchable structure applicable to either foot of a table or chair. The present invention is applied only to one foot of a table or chair. In this case, the applicable stretchable structure of the foot is included in the technical scope of the present invention.
