Detailed Description

In order that the above objects, features and advantages of the present invention can be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.

In the description of the present invention, the term "at least one" means one or more than one unless explicitly defined otherwise. The terms "first," "second," "third," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

The specific embodiment of the invention is as follows:

example 1:

as shown in fig. 4, the present invention provides a multifunctional seat including: base 1 and symmetry set up the supporting seat 2 in base 1 both sides, and both rotate to be connected.

Before the multifunctional chair of the present invention is introduced, another sitting-standing chair is introduced, as shown in fig. 1-3, as another implementation manner of the sitting-standing chair, that is, a sitting-standing chair with three sitting surfaces, a main support 101 as a main body of the sitting surface and connecting to a chassis or a base, and side supports 102 symmetrically disposed at the left and right sides of the main support 101, wherein the main support 101 is always in a flat-laying posture, the side supports 102 rotate relative to the main support 101, and the sitting-standing chair has a sitting posture state and a standing posture state through different positions reached by the side supports 102 after rotating; the main support 101 is clamped between the two side supports 102, and in a sitting posture, the main support 101 and the two side supports 102 together form a flat sitting surface for supporting a user to sit flat.

This embodiment differs from the chair shown in figures 1-3 above in that the main support is omitted from the middle, and instead a base is arranged directly below the side supports for support, as will be described in more detail below:

as shown in fig. 4 and 6, the base 1 is configured to support the supporting base 2, a seat supporting assembly is disposed below the base 1, the seat supporting assembly in this embodiment includes a lifting air rod 33 and a five-star foot 34, the lifting air rod 33 is connected between the five-star foot 34 and the base 1, and the base 1 can be lifted by the lifting air rod 33.

The support seat 2 is a plate-shaped body, the support seat 2 has a seat inner side 3 close to the base 1 and a seat outer side 4 far away from the base 1 along the width direction, the seat outer side 4 is the outer edge of the support seat 2, and is a broad term referring to the outer edge area of the support seat 2, and generally refers to a part capable of supporting a human body to sit in a standing posture state.

The whole base 1 is positioned below the supporting seat 2; visually, in the whole seat, the two are slightly overlapped, but the base 1 is positioned below the supporting seat 2; from the overall arrangement, the base 1 is arranged below the supporting seat 2, and the lifting air rod 33 is required to be connected below the base 1.

The chair has a sitting posture state and a standing posture state; in a sitting posture: the supporting seat 2 is in a flat-laying posture to form a seat surface for a user to sit flatly, and the seat surface can be a plane or a curved surface conforming to human engineering; when the sitting posture state is converted into the standing posture state, the supporting seats 2 on the two sides are respectively turned upwards to be in the vertical posture, the vertical posture does not necessarily limit the supporting seats 2 to be kept strictly vertical to the horizontal plane, more means that the outer sides 4 of the supporting seats 2 can be at higher heights after the supporting seats 2 are turned upwards, the base 1 can be kept fixed in the upward turning process, and the supporting seats 2 can meet the height using requirements of most people in the standing posture state at the moment; when the supporting seat 2 is in the upright posture and cannot meet the sitting requirement of a human body in the standing posture, for example, a user is too high or short, the height of the base 1 can be controlled by the lifting air rod 33, so that the requirement of the user can be met.

As shown in fig. 7, the base 1 includes a hollow body 601, the body 601 is a strip-shaped plate-shaped body arranged along the seat depth direction, the middle part of the body 601 is bent downwards and forms an inverted arch integrally; the two ends of the body 601 extend upward to form a rotation supporting portion 604, and the seat front side 602 and the seat rear side 603 of the supporting seat 2 are rotatably connected with the adjacent rotation supporting portions 604.

The above-mentioned rotational connection is realized by: the seat front side 602 and the seat rear side 603 of the support seat 2 are formed with a connection part 605 connected with the rotation support part 604, and the connection part 605 and the rotation support part 604 are arranged in the front-back direction: the support seat 2 is clamped between the two rotary supporting parts 604 and is close to the front and rear end connecting parts 605 at the position of the inner side 3 of the seat; the connecting portions 605 are recessed along the seat depth direction, and the recesses formed on the support seat 2 by the two connecting portions 605 just allow the rotation supporting portion 604 to enter, and are rotatably connected at the recessed portions of the connecting portions 605 through a rotating shaft 7.

Of course, there are other ways to realize the rotary connection between the supporting base 2 and the base 1, such as the connecting portion 605 of the supporting base 2 jointly clamps the two rotary supporting portions 604 between the two connecting portions 605; or, the connection portions 605 and the rotation supporting portions 604 are disposed up and down, and the connection portions 605 of the supporting seat 2 are disposed above the rotation supporting portions 604 adjacent to each other and supported by the rotation supporting portions 604, but are not specifically described in this embodiment; in this embodiment, the implementation described in the previous paragraph is taken.

After the two supporting seats 2 are installed on the base 1, a linear slit 606 penetrating through the front and the back of the supporting seats 2 is formed between the inner sides 3 of the two supporting seats 2, and the width of the slit 606 is configured to ensure that the two supporting seats 2 are not interfered when being turned upwards; considering both the aesthetic property and the stability in the sitting posture, the width of the slit 606 is always not larger than the width between the rotary shafts 7 on the two supporting seats 2.

It should be noted that when the width of the slit 606 is zero, i.e. the inner sides 3 of the two supporting seats 2 in the sitting posture are attached, an elastic separation mechanism can be arranged; as shown in fig. 18, the elastic separation mechanism includes a separation spring 607, a sliding groove 608 is formed on the rotation support portion 604, the rotating shaft 7 is disposed in the sliding groove 608 and is in sliding fit with the sliding groove 608, a spring seat 609 for fixing the separation spring 607 extends from one end of the sliding groove 608 along the direction of the sliding groove 608, and the other end of the separation spring 607 is fixedly connected to the rotating shaft 7; when the sitting posture and standing posture states need to be switched, the supporting seat 2 which is attached together is separated and then turned over, and the supporting seat is returned after turning over is finished, and switching is finished; in the process, the process of separating and resetting the supporting seat 2 through the elastic separating mechanism has guidance, so that the process is smooth and can be simply adjusted to a proper position.

The elastic separation mechanism can be arranged for two supporting seats 2 or only one supporting seat 2.

The above paragraphs describe the core idea of the invention, and the purpose of seat-to-seat conversion is achieved by the upward turning of the supporting seat 2; in practical use, in order to improve the comfort of use and the sitting posture of a human body in a standing posture state, the support seat 2 is optimally designed, specifically, as shown in fig. 4-7, a standing posture support part 10 extends downwards from the seat outer side 4, the standing posture support part 10 is a bent plate which is in a tab shape and is provided with a curved surface, and the support seat 2 and the standing posture support part 10 are integrally formed; when the supporting seat 2 is turned upwards and fixed, the two standing position supporting parts 10 are close together, meanwhile, the standing position supporting parts 10 are converted from a drooping state into a roughly horizontal state which is beneficial to supporting a human body, and at the moment, the two standing position supporting parts 10 form a saddle with a narrower width compared with a sitting position surface in a sitting position state, so that a user can sit on the saddle.

The above paragraphs illustrate the design points of the present invention, and in practical use, the supporting seat 2 needs to be limited in the sitting and standing positions, and the limiting manner can be various, and the following examples are as follows:

as shown in fig. 7 and 8, a lock mechanism including a stopper 53 and a lock member 54 is provided in the seat.

In order to enable the seat to be used in the sitting and standing states, the sitting and standing states need to be locked by a locking mechanism, and the seat can be unlocked when the sitting and standing states need to be converted; the locking mechanism of the seat is specifically described as follows:
