Description

Combination assembly for enhancing assembling and a furniture apparatus for body support having the same

The present invention relates to a coupling assembly having improved assembly and a body support furniture device having the same, and more particularly, an insert and an accommodation cap are installed in each of the frames of the body support furniture device so that they can be coupled by a simple insertion method. Since it is configured so that it can be combined without the use of a separate fastening tool, it is possible to maximize assembling, workability and convenience. And it relates to a coupling assembly having an improved assembly property capable of increasing transport efficiency and reducing costs, and a furniture device for body support having the same.

In recent years, as the industry has developed and advanced, furniture and household items have been diversified, and in particular, various body support furniture devices such as chairs, sofas, vehicle seats, and beds are widely used to support a seated body part to reduce body fatigue. is being used

Such a furniture device for body support is typically composed of a main frame, a plurality of accessory frames coupled to the main frame, and accessories installed to surround the outside of the frame, such as armrests and back mattresses, as a framework. At this time, as a method of coupling the frames, a method using a coupling means such as welding or a bolt and a nut is mainly used, and accordingly, a worker or a user combines the frames using a separate coupling tool such as a dryer or a welding machine when assembling. , this coupling method has a disadvantage in that the operation is cumbersome and complicated because a separate coupling means and a coupling tool are used, and thus the efficiency and convenience of the operation are significantly lowered.

In particular, in the case of a frame (or accessory) that supports the body among the accessories of the furniture device for body support, when the frame (or accessory) has a predetermined elastic force and elastic force in the direction pressed by the body, muscle fatigue, seating comfort, and contact feeling are improved. However, in the conventional coupling method, since the frame is coupled to another frame in a fixed state by means of a coupling means, no elasticity or resilient force is given to the frame itself, and thus the seating and contact feeling are deteriorated.

For example, among the accessories of the sofa, the backrest or armrest supports the back or arm of the body, so a certain amount of elasticity and elasticity are required for the frame of the accessory, but the frame of the accessory (backrest or armrest) is different from other frames When combined through bolt fastening or welding, no elasticity and resilient force are given to the frame of the backrest or armrest, so seating and contact feeling are significantly reduced, and assembly is cumbersome and complicated, resulting in poor work efficiency and convenience.

In order to solve this problem, research is being conducted to increase cushioning and cushioning by installing cushions, cushions, mattresses, springs, etc., in accessories on which the body is seated, such as backrests and armrests, but the frame itself does not yet have elasticity. Research on the coupling structure and method to improve assembly while allowing it to be provided is insufficient.
