Description

A connecting piece applied to the expanded function of a folding chair

The present invention relates to a connecting piece applied to the expansion function of a folding chair. In detail, it is a connecting piece for connecting a rocker and a support leg of the seat, so that a simple seat is expanded into a connecting piece with the function of a rocking chair.

According to this, the existing rocking chair is often displayed in ordinary households. The rocking chair includes a base and a swinging bracket. The swinging bracket is fixed under the base and is provided with two opposite curved rods. The two curved rods Leaning against the ground, and by the height difference between the two curved rods and the ground and the shaking of manpower, the rocking chair can swing back and forth on the floor, which is different from the riding experience of a general fixed seat.

However, the seat body and the swing bracket of the existing rocking chair are fixed to each other, so the existing rocking chair is bulky. Therefore, the existing rocking chair requires a lot of space in the transportation tool during transportation, which causes poor transportation efficiency. When the rocking chair is placed in It is also difficult to store indoors due to its large size.

Please refer to the Republic of China Patent Certificate No. M549017, which is the "multifunctional rocking chair structure" previously applied by the inventor. It includes a seat and two rockers. The seat system has four supporting legs and two rocker systems. Each is an arc-shaped rod body, and the two rockers are pivoted on the inner arc surface of each of the two sleeve rods that are sleeved on the supporting legs. The joints of the four supporting legs and the sleeve rods each form a protrusion. The upper and inner sides are hollowed out. The sleeve rod is formed with an abutting edge below the inner side surface, and the sleeve rod is formed with a horizontal groove that can be buckled into the protrusion; in this way, it can be used as a general seat In addition, it can be changed into a rocking chair for passengers to swing comfortably, and different riding applications can be achieved without the need to purchase two seats, which not only can effectively reduce the purchase cost, but also save the space for storing seats.

However, the above creation still has shortcomings in the structure of the fixed base support foot and the rocker, because the design must be inserted in a slightly slanted manner during assembly, and then be fastened after being aligned. Not only the assembly is not intuitive enough, but some microstructure tolerances must be reserved in this way. However, the reserved tolerances are likely to cause the shortcomings of shaking and abnormal noise when using the rocking chair.

In view of this, based on years of experience in the development of related industries, the creators have in-depth discussions on the problems faced by existing creations and actively seek solutions. After long-term research and development, they finally succeeded in creating a The multifunctional rocking chair structure is a seat structure with a detachable rocker at the bottom. The user can replace it with a rocking chair or a normal seat according to the sitting posture requirements.

The invention relates to a connecting piece applied to the expansion function of a folding chair, which is a connecting piece for connecting a rocker and a support leg of the seat, so that a simple seat is expanded into a connecting piece with the function of a rocking chair.

In order to achieve the aforementioned creative purpose, the present invention "a connecting piece applied to the expanded function of a folding chair", the connecting piece includes a first connecting portion and a second connecting portion, and the first connecting portion has a first component, And at both ends of the first part, there is a second part and a third part that extend in the same direction. A fitting notch for the rocker is defined between the second part and the third part, and the first part Each of the two parts and the third part is formed with a lock hole, the second joint part is arranged on the first part, and an assembly port for the support legs of the seat is formed above the second joint part;

In this way, by inserting the rocker into the fitting notch, the connecting piece can be combined with the rocker by locking the screw in the key hole, and then inserting the support foot of the seat into the assembly opening, then the seat can be placed under the seat Additional rocker structure makes it used as a rocking chair.

The aforementioned connecting member includes a stabilizer fastener, the stabilizer fastener includes two extension plates pivoted to the outside of the second member and the third member, the stabilizer fastener has a pivot so that it can be placed in The arc-shaped fitting on one side of the seat support foot is formed with a buckle for the protruding insertion of the supporting foot.

The aforementioned first component is formed with a through hole, the second joining part is a plastic cone with a narrow upper and a wide bottom, and the assembly opening is formed above the second joining part, and the tapered part of the second joining part is The plug is placed in the perforation, showing that the wide part is in the notch and the narrow part is through The first joint shape is shown.

It can be seen from the foregoing creation content that the present invention "a connector applied to the expansion of folding chairs" is capable of expanding a general seat into a rocking chair in addition to basic seating functions to enhance leisure applications; in addition, the present invention is more capable The following advantages;

1. The present invention is to provide the seat support leg to be directly inserted into the rocker through the assembly port, which can effectively improve the convenience and stability of the assembly.

2. The first coupling part of the connecting piece of the present invention is combined with the rocker in a screw-locked pivoting manner, so the corresponding angle of the assembly opening and the seat support foot can be adjusted at will to facilitate the combination of the seat and the rocker.

3. The second joint part of the present invention is made of elastic plastic, so it can effectively improve the stability when it is inserted and combined with the supporting leg, and can buffer the shaking of the structure when the rocking chair swings back and forth, avoiding collisions It can be said that the present invention is a very practical and progressive creation, which is worthy of being promoted by the industry and made public.
