Multipurpose foldable A-type support with double coupling

The present invention relates to a multi-purpose foldable A-type support that can be folded and stored and in which each component is double-coupled through fitting.

Recently, the importance of the work-life balance, which balances work and vacation, is increasing, and accordingly, more and more people enjoy traveling and camping for relaxation.

Among them, each component of a support or table capable of stably supporting a heavy object must be firmly coupled in order to stably perform its role, but in this case, it is bulky and has a disadvantage in that mobility is poor.

For this reason, Korean Utility Model Registration No. 20-0475341 discloses a table that implements a function in which two top plates are overlapped and a leg member is folded together. Discloses a camping table that includes a function to do.

However, the above methods are foldable or deformable, so they are convenient, but the coupling between each component is not solid. The downside is that it is difficult to transform.

For this reason, there is a demand for a table or support that can be freely folded and stored, and which can be freely deformed by configuring each configuration with a fitting rather than a screw, pin, screw surface, etc.

In order to solve the above problems, it is possible to fold and store when not in use, and when in use, each component is combined with a fitting coupling to provide a multi-purpose foldable A-type support that is conveniently coupled without a pin or screw surface. .

Another object is to provide a foldable A-type support that can be used for table purposes by adding a top plate to the top of the support.

It relates to a multi-purpose foldable A-type support that is double coupled by the center hole and the curved surface of the support.

In the above embodiment, a first groove extending in a horizontal direction of the case and a second groove having one end communicating with the first groove and the other end extending in a vertical direction of the case are formed inside the case. The first groove and the second groove may provide a path for the connecting shaft to move inside the case.

In the above embodiment, the leg part further includes a leg fixture extending a predetermined length, one end of the leg fixture is rotationally coupled to any one leg selected from among the leg parts, and the leg fixture The other end may be fitted and fixed to the other one of the legs.

In the above embodiment, when the angle between the leg fixture and the leg that is rotated with the leg fixture is defined as a, and the angle between the leg fixture and the leg fitted and fixed to the leg fixture is defined as b, the a is 90 ° ≤ a ≤ 110 °, b may satisfy 70 ° ≤ b ≤ 90 °.

In the above embodiment, at least one coupling screw formed on the top plate covering the upper portion of the multipurpose foldable A-type support and the upper portion of the case, and fitted with the coupling screw may be further included.

The multi-purpose foldable A-type support that is double-coupled according to the present invention is fitted and coupled to each component during assembly, and can conveniently and stably support heavy objects by double-coupled.

Through this, it is possible to secure the efficiency of space by transporting and storing the support in a folded state, and when in use, the support can be used stably by doubly combining the support.

In addition, a groove may be formed at the other end of the leg fixing table 45 so that it can be fitted and fixed to the leg. It can be fitted and fixed with the other leg through the groove.

For example, when the leg portion exists as a first leg and a second leg, the leg fixing base 45 is rotationally coupled to the first leg through the fixing pin 47 and the second leg through the groove. can be fitted into.

At this time, when the angle between the leg fixture 45 and the leg rotated with the leg fixture is defined as a, and the angle between the leg fixture and the leg fitted and fixed to the leg fixture is defined as b, the a is 90 ≤ a ≤ 110, the b may be fixed at an angle of 70 ≤ b ≤ 90.

In other words, the angle between the first leg coupled through the fixing pin 47 and the leg fixture 45 may be 90 to 110°, and the second leg coupled through the groove of the leg fixture 45 The angle between the leg and the leg fixing table 45 may be provided at 70 to 90°.

If the angle between the first leg and the leg support 45 is less than 90° or exceeds 110°, the leg support 45 is not stable and fixed, fixing the distance between the first leg and the second leg. cannot fulfill the role of

In addition, when the angle between the second leg and the leg support 45 is less than 70° or exceeds 90°, the leg support 45 automatically separates from the second leg due to gravity.

More preferably, it is most preferable that the first leg and the leg support 45 are fixed perpendicularly to each other, and the angle between the second leg and the leg support 45 is 75 ° to 80 °.

The configuration of the multi-purpose foldable A-type support 100 that is double coupled according to an embodiment of the present invention has been described above. In the present invention, the coupling of the fixing jaw 31 and the central groove 21 and the coupling of the leg 41 and the curved surface 25 may be coupled in a double manner.

Through this, it is possible to distribute the stress that can be concentrated on one coupling part, and by stably distributing the stress, the support can stably support a heavier weight.

In addition, the present invention can be easily disassembled and assembled by adopting a fitting coupling rather than a screw, pin, or screw surface for the main coupling of the center bar 10, the support portion 20, the case 30, and the leg portion 40. It can be used conveniently by omitting the work of inserting a pin or turning the screw surface. Through this, user convenience can be improved.
