Patent Application
20150208808
The present utility model relates to a leisure chair, in particular to a moon chair with a simple connecting seat structure.
A moon chair is a leisure chair which is specially designed according to ergonomics for the sake of health of human. This chair is very comfortable, the area of the seat thereof is very large, the entire body of the human can be enclosed when the human sits on the chair, a feeling of being hugged by the chair is obtained and the chair is very comfortable and warm. In order to facilitate the use, generally the moon chair is designed to be in a foldable structure; since the moon chair generally uses a circular rest frame as a backrest and armrest rods, movement of more than two degrees of freedom is produced by the rest frame and the supporting legs during folding, i.e., connecting seats between the rest frame and the supporting legs can realize rotatable connection of at least two different degrees of freedom, so that the connecting parts of this kind are caused to be comparatively complex. Taking a moon chair structure disclosed by the specification of Chinese utility model patent CN202496762U as an example, the connecting seat thereof is formed by assembling two parts, the structure of the parts is complex and the production cost is comparatively high. In addition, the more component parts of the connecting seat are, the more easily fatigue failure is caused and service life is influenced.
The present utility model relates to an improvement to a connecting seat of a moon chair and the purpose of the present utility model is to provide a moon chair with a simpler connecting seat structure.
In order to realize the above-mentioned purpose, the present utility model adopts the following technical solution:
A moon chair comprises front supporting legs, rear supporting legs and a rest frame which is connected onto the front supporting legs and the rear supporting legs, wherein the rest frame is of the shape of a circular ring which is obliquely erected when the rest frame is unfolded, the front supporting legs are connected with the rest frame through first connecting seats, the rear supporting legs are connected with the rest frame through second connecting seats, each of the first connecting seats and the second connecting seats comprises an integral bent metal sheet, the two ends of the metal sheet are respectively provided with pin holes for arranging connecting pins in a penetrating manner, the metal sheets on the first connecting seats are respectively and movably connected with the front supporting legs and the rest frame through the connecting pins, and the metal sheets on the second connecting seats are respectively and movably connected with the rear supporting legs and the rest frame through the connecting pins.
After the above-mentioned solution is adopted, since the major component of the connecting seat is the integral bent metal sheet, the structure is simple and the metal sheet can be molded directly by adopting stamping; and since the manufacturing cost of a stamping mold is lower, compared with other complex connecting seat structures, the production cost can be obviously reduced. After the metal sheet is bent, the rotatable connection of two different degrees of freedom of the connecting seat can be very easily realized through connecting pins at the two ends of the metal sheet, and the production and assembling are comparatively convenient.
As an improvement to the present utility model, one end of the metal sheet on the first connecting seat is bent to a U-shape to cover the corresponding front supporting leg. The purpose of the improvement is to increase the contact area between the metal sheet and the front supporting leg, so as to enable the torque transfer between the first connecting seats and the front supporting legs to be more stable and avoid the situation that the connecting positions of connecting pins easily get loose due to the reason that the torque is transferred only through the connecting pins.
Similarly, one end of the metal sheet on the second connecting seat can also be bent to a U-shape to cover the corresponding rear supporting leg.
As a further improvement to the present utility model, the number of the front supporting legs and the number of the rear supporting legs are respectively two, and the part, between the two front supporting legs, of the rest frame is of a disconnected structure. This improvement can prevent the knee joints of legs from being pressed against by the rest frame and increase the sitting comfort when a user sits on or leans against the moon chair.
As a preference, the metal sheet is an iron sheet or a stainless steel sheet. The iron sheet or the stainless steel sheet has certain strength, is not easily deformed and is easy to stamp.
In the figures, front supporting leg-1, rear supporting leg-2, rest frame-3, first connecting seat-4, second connecting seat-5, metal sheet-6, 7, connecting pin-8, 9, 10, 11.
The present utility model is further described below in combination with the drawings and the specific embodiments.

As shown in
The present utility model is described above in details in combination with the drawings. However, the embodiments of the present utility model are not limited to the above-mentioned embodiments. One skilled in the art can make various modifications to the present utility model according to the prior art, for example, replacing the connecting pin in the present utility model with screws. However, all of those modifications also belong to the protection scope of the present utility model.
