Description

a frame chair

technical field

The embodiments of the present invention relate to the field of furniture, in particular to a frame chair.

Background technique

Several of the most representative armchairs in ancient China, such as the four-head official hat chair, the male official hat chair and the rose chair, are all products of functionalism, which are the most in line with the modern ecological design concept and Original design with ergonomic principles. Their basic structure is an ultra-stable composite frame system consisting of a seat frame plus a quadruped and crossbar system, coupled with an exquisite and durable mortise and tenon structure system, making this armchair a model of modern functionalist design.

In daily life, frame chairs are relatively commonly used furniture. There are many styles of frame chairs, including basic components such as frames, support frames, seating surfaces, and backrests.

However, the existing frame chairs are relatively traditional, have a complex structure, cannot reach the best angle conforming to the principles of ergonomic design, and have insufficient comfort in use.

Optionally, the side brackets are square brackets.

Optionally, the sitting surface is composed of more than two slats.

Optionally, the abutting surface is composed of more than two slats.

Compared with prior art, the beneficial effect of the present invention is:

The independent design of the side frame, seat surface and backrest completely breaks away from the blended composite structure model in the design of ancient Chinese armchairs. The side frame, seat surface and backrest form complete and independent furniture components. There is a fixed connection between them, and the angle between the planes between the seat surface and the back surface is an obtuse angle. The frame chair with the above-mentioned structure has a simple structure and conforms to the principle of ergonomic design.

Detailed ways

The embodiment of the present invention provides a frame chair, which is used to solve the technical problems of the existing frame chairs with complex structure and unacceptable ergonomic design.

In order to make the purpose, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the following The described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Embodiment one

Referring to Fig. 1 to Fig. 5, an embodiment of a frame chair provided by an embodiment of the present invention includes:

The basic parts of the frame chair of this embodiment are two independent side brackets 1, the seat surface 2 and the back surface 3. The frame chair of this embodiment adopts the combination structure mode of the above parts. The frame chair of the embodiment of the present invention mainly For life, leisure and other occasions.

As shown in Figure 1, the side bracket 1 is two independent brackets, the side bracket 1 is a square, the seat surface 2 and the back surface 3 are respectively located between the two side brackets 1, the seat surface 2 is inclined downward relative to the horizontal plane, and the back surface 3 is inclined backward relative to the vertical plane, and the angle between the plane where the seating surface 2 and the resting surface 3 are located is an obtuse angle. In this embodiment, the angle at which the seat surface 2 inclines downward relative to the horizontal plane is 6°, and the angle at which the rest surface 3 inclines backward relative to the vertical plane is 20°.

It can be understood that the side bracket 1 is not only an armrest, but also a bracket on which the seat surface 2 and the back surface 3 rely.

As shown in Figures 1 and 2, the support frame 4 is two vertical support frames, which are respectively fixed in the middle of the two side supports 1 and directly embedded in the upper and lower frame slats of the side support 1. The support frame 4 is not only centered , and simultaneously undertake the structurally stable support of the side bracket 1 and the bearing of the components of the seat surface 2 and the seat surface 3.

It should be noted that the outside of the support frame 4 veneer can be engraved with bas-relief patterns such as grass dragon patterns and plum, orchid, bamboo and chrysanthemum patterns, so that the frame chair is beautiful while having practical functions.

As shown in Figure 1, one end of the seat surface 2 is fixedly connected to the vertical side of the side bracket 1, the other end of the seat surface 2 is fixedly connected to the support frame 4, one end of the seat surface 3 is fixedly connected to the side frame 1, and the other end of the seat surface 3 is connected to the support frame 4. Frame 4 is fixedly connected.

As shown in FIG. 3 , the bolt holes 8 are located on the side bracket 1 and the support frame 4 respectively, and the fixed connection between the seat surface 2 and the rest surface 3 and the side bracket 1 and the support frame 4 is a bolt connection. It should be noted that, in this embodiment, the number of bolt holes 8 is 8 to ensure the stability of the product structure.
