Description

Structural assembly of a reclining office chair with a slight angle

The present invention mainly belongs to the structure of an office chair, and more specifically, particularly refers to a structural assembly of a reclining office chair with a slight angle.

It is known that the reclining structure of chairs is designed for a large reclining angle, which cannot meet the needs of some customers who only need a slight reclining angle.

In view of this, the creator of this case conducted an in-depth discussion on the aforementioned deficiencies based on his many years of research and development experience in related fields, and actively sought solutions based on the aforementioned needs. After a long period of hard research and multiple tests, this creation was finally completed.

The present invention mainly belongs to the structure of an office chair, and more specifically, particularly refers to a structural assembly of a reclining office chair with a slight angle.

To achieve the above-mentioned purpose, the present invention is a structural assembly 1 for a user 4 to sit on a reclining office chair with a slight angle. The structural assembly 1 is arranged on a structural assembly 1 connecting a seat cushion 2 and a chair back 3, and comprises:

The seat cushion connecting seat 10, a set of springs 11, a seat back connecting seat 12, and a connecting shaft 13 are composed.

The structural assembly 1 of the present invention can connect one end of the cushion connecting seat 10 to the cushion 2, and two accommodating spaces 100 are arranged above the cushion connecting seat 10. The accommodating spaces 100 can be arranged with springs 11, and the cushion connecting seat 10 can be connected to the backrest connecting seat 12 through the connecting shaft 13 above the cushion connecting seat 10 where the spring 11 is installed, so as to form the structural assembly 1 of the present invention.

Through the structural assembly 1 of the present invention, the seat 2 connected to the seat connecting seat 10 and the seat back 3 connected to the seat back connecting seat 12 can be used by a user 4 sitting on the upper side to lie on his back at a slight angle.

Therefore, in summary, the advantages of the present invention are:

1. From the above preferred embodiments, it can be seen that the present invention uses a structural assembly 1, which is arranged on the structural assembly 1 connecting the seat cushion 2 and the chair back 3 to create a position for the user 4 to lie back at a slight angle between the seat cushion 2 and the chair back 3 through the structural assembly 1 when sitting.

In order to provide a more detailed understanding of the purpose, function, features and structure of the present invention, preferred embodiments are described below with reference to the accompanying drawings.

First, please refer to Figures 1 and 2, which are respectively: Figure 1 is a three-dimensional diagram of a preferred embodiment of the present invention, and Figure 2 is a partial enlarged front view of a preferred embodiment of the present invention when lying supine.

As shown in FIG. 1 and FIG. 2 , a structural assembly 1 of a new type of office chair with a slight reclining angle for a user 4 is shown. The structural assembly 1 is arranged on a structural assembly 1 connecting a seat cushion 2 and a chair back 3 .

Please refer to Figures 3 and 4, which are respectively: Figure 3 is a three-dimensional exploded view of the new structural assembly, and Figure 4 is a three-dimensional sectional view of the new structural assembly before lying on its back.

As shown in FIG. 3 and FIG. 4 , the structural assembly 1 of the present invention comprises: a cushion connecting seat 10, a set of springs 11, a seat back connecting seat 12, and a connecting shaft 13.

The seat cushion connecting seat 10 and the chair back connecting seat 12 can be made of plastic, polypropylene, polyamide, polyvinyl chloride, polyurethane, iron, steel, chromium, stainless steel, aluminum, or wood.

The spring 11 can be composed of a compression spring, a disc spring, or a gas spring.

The connecting shaft 13 can be made of iron, steel, chromium, stainless steel, aluminum, or alloy steel.

Please continue to refer to Figures 2, 3, and 4, which are respectively: Figure 2 is a partial enlarged front view of the preferred embodiment of the present invention before lying on one's back, Figure 3 is a three-dimensional exploded view of the present invention's structural assembly, and Figure 4 is a three-dimensional sectional view of the present invention's structural assembly before lying on one's back.

As shown in Figures 2, 3, and 4, and according to the above description, the structural assembly 1 of the present invention can connect one end of the above-mentioned seat cushion connecting seat 10 to the seat cushion 2, and two accommodating spaces 100 are set above the seat cushion connecting seat 10. The above-mentioned accommodating spaces 100 can be set with springs 11, and the seat cushion connecting seat 10 can be connected to the seat back connecting seat 12 through the above-mentioned connecting shaft 13 above the seat cushion connecting seat 10 where the spring 11 is installed, so as to form the structural assembly 1 of the present invention.

Please refer to Figures 5 and 6, which are respectively: Figure 5 is a partial enlarged front view of the novel preferred embodiment after lying on the back, and Figure 6 is a three-dimensional sectional view of the novel structural assembly after lying on the back.

As shown in FIG. 5 and FIG. 6, they are partial enlarged front views of a preferred embodiment of the present invention after lying on one's back. Through the structural assembly 1 of the present invention, the seat 2 connected to the seat connecting seat 10 and the chair back 3 connected to the chair back connecting seat 12 can be used by a user 4 sitting on the upper side to make the structural assembly 1 lie on one's back at a slight angle.

The following are the relevant diagrams for reference of user 4 riding this creation:

Please continue to refer to Figures 2 and 5 in conjunction with Figures 4 and 6. Figure 2 is a partial enlarged view of the front view of the preferred embodiment of the present invention when lying on one's back, and Figure 5 is a partial enlarged view of the front view of the preferred embodiment of the present invention when lying on one's back.

As shown in FIG. 2 and FIG. 4 , the user 4 is sitting on the seat 2 and has not yet reclined. At this time, the structural assembly 1 connecting the seat 2 and the chair back 3 does not have any reclining stroke due to the absence of external force.

5 and 6, the user 4 sits on the seat 2 and starts to lie back. Due to the external force of the user 4, the structural assembly 1 connecting the seat 2 and the chair back 3 generates a slight reclining stroke through the limit structure generated by the seat connecting seat 10 and the chair back connecting seat 12 inside the structural assembly 1 of the present invention and the spring 11 provided inside the structural assembly 1.

In summary, the advantages of this new type are:

1. From the above preferred embodiments, it can be seen that the new invention uses a structural assembly 1, which is arranged on the structural assembly 1 connecting the seat cushion 2 and the chair back 3 to create a position for the user 4 to lie back at a slight angle between the seat cushion 2 and the chair back 3 when sitting.

Therefore, this new model has excellent progress and practicality among similar products. At the same time, after searching domestic and foreign technical data and literature on this type of structure, it is indeed found that there is no identical or similar structure existing before the application of this case. Therefore, this case should have met the patent requirements of "creativity", "suitability for industrial application" and "progress", and the application is filed in accordance with the law.

However, the above-mentioned are only the preferred embodiments of the present invention. Any other equivalent structural changes made by applying the present invention specification and the scope of patent application should be included in the scope of patent application of the present invention.
