Description

Technical Field

[0001] The utility model belongs to the technical field of combined tables and chairs, and relates to a combined table and chair based on an integrally rotating tabletop. Background Art

[0002] In the existing table and chair combination structure, the connection between the table top and the table legs is relatively fixed, resulting in the table top being unable to be adjusted and moved relative to the table legs. Although in the prior art, a turntable is also provided on the top of the table top to achieve rotation, it is only the turntable that rotates alone, rather than the entire table top rotating relative to the table legs. Since the table top and the table legs cannot rotate relative to each other, this causes the existing table structure to be inflexible in two usage situations: a person sits around the table top and a seat needs to be stored between the table legs. That is, there will always be a situation where the legs of the person are blocked by the table legs or the seat cannot be tightly stored between the table legs.

[0003] Therefore, in view of the above-mentioned defects of the existing combined table and chair structure, the utility model discloses a combined table and chair based on an integrally rotating tabletop. Utility Model Content

[0004] The purpose of the utility model is to provide a combined table and chair based on an integrally rotating table top, which can flexibly rotate the table top structure of the table body as a whole, and then adjust the position of the edge of the table top structure relative to the placement space between the table legs. In view of the situation where people sit around, the table legs can be avoided from interfering with the human body, and the comfort of the human body sitting around the table top can be ensured; in view of the situation where seats are stored, the seats can be completely stored between the table legs and the seats and the table top can be ensured to form a compact structure to save space.

[0005] The utility model is realized by the following technical solutions:

[0007] The desktop assembly of the table body can rotate between a first position and a second position relative to the table legs. The first position refers to the position where the seat is stored in the placement space between the table legs, that is, by rotating the desktop assembly, the edges of the desktop assembly are rotated to a position perpendicular to the neutral plane of any table leg, that is, the corner position of the desktop assembly is ensured to be rotated to the placement space between adjacent table legs, and then the seat can be assembled into the placement space. At this time, the chair body is located inside the placement space, and the contour of the chair back is closely fitted with the edge contour of the desktop assembly, thereby effectively reducing the space occupied by the table body and the seat after combination, and making the table body and the seat more beautiful after combination.

[0008] The second position refers to the position where the human body sits around the desktop assembly. In order to ensure the comfort of the human body and avoid the legs of the human body being obstructed by the table legs, the desktop assembly is rotated at this time so that the edge of the desktop assembly is rotated to the placement space between the table legs. At this time, the human body sits on the mount in a posture facing the edge of the desktop assembly and can extend the legs into the placement space between the table legs to avoid the legs being obstructed by the table legs, thereby improving the riding comfort of the human body.

[0009] In order to better implement the utility model, further, it also includes a desktop bracket, the bottom of the desktop bracket is evenly spaced along the circumferential direction with at least three groups of table legs, and the top of the desktop bracket is rotatably provided with a desktop assembly.

[0012] In order to better realize the utility model, further, the elastic rotation limit device includes a pull rod, a spring, and a limit pin. The pull rod is slidably arranged on the bottom surface of the desktop bracket along the vertical direction. The outside of the pull rod is provided with a spring that contacts the bottom surface of the desktop assembly. A limit pin is provided at the top of the pull rod corresponding to the limit hole.

[0013] In order to better implement the utility model, further, the central angle formed between the adjacent limiting holes at the bottom of the desktop assembly and the angle between the two adjacent sets of table legs meet:

[0014] α = θ / 2;

[0015] Where: α represents the central angle formed between adjacent limiting holes; θ represents the angle between two adjacent sets of table legs;

[0016] The outline shape of the tabletop assembly is a polygon, and the number of the table legs is equal to the number of edges of the polygon.

[0017] In order to better realize the utility model, further, the outline of the desktop assembly is set to a regular quadrilateral, the number of the table legs is four groups; the angle between adjacent table legs is 90°, and the central angle formed between adjacent limiting holes at the bottom of the desktop assembly is 45°.

[0018] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0019] The utility model can flexibly rotate the desktop assembly as a whole according to two usage situations of splitting the seats and storing the seats when people sit around the table legs, by rotatably setting the desktop assembly on the top of the table legs. The desktop assembly is supported by the table legs, and the desktop assembly can be flexibly rotated as a whole according to two usage situations of splitting the seats and storing the seats in combination, thereby adjusting the position relationship of the edges of the desktop assembly relative to the placement space between adjacent table legs, so as to ensure that the legs of people can be extended into the placement space when people sit around the table legs, so as to avoid the legs of people being blocked by the table legs; or the edges of the desktop assembly are adjusted to be perpendicular to the neutral plane of the table legs, so as to ensure that the seats can be tightly stored between the table legs; at the same time, in the process of rotating the desktop assembly, the rotation interval angle of the desktop assembly is limited by the elastic rotation limit device, so as to assist the desktop assembly to quickly rotate into place, making the rotation and use of the desktop assembly more convenient.

[0038] like Figure 2 , Figure 3 As shown, the combined table and chair includes a table body A and four seats B. Four sets of table legs 2 are evenly spaced along the circumferential direction at the bottom of the tabletop assembly 4, thereby forming four placement spaces 3 at the bottom of the tabletop assembly 2, and the four seats B are just combined into the four placement spaces 3, completing the combination of the table body A and the seats B. After the table body A and the seats B are combined, the chair body 6 of the seat B is accommodated into the placement space 3, and at the same time, the contour of the backrest 7 close to the side of the table body A is just closely fitted with the edge contour of the tabletop assembly 4 from the top view, thereby ensuring that the table body A and the seats B are closely combined, reducing the space occupied by the table and chair combination in the combined state, and also making the table and chair combination more concise and beautiful.

[0039] like Figure 1 , Figure 8 As shown, the table top assembly 4 is in the first position, that is, the edge of the table top assembly 4 is perpendicular to the neutral plane of the table leg 2, and the outline of the body 6 of the seat B in the top view is smaller than or equal to the outline of the placement space 3, ensuring that the body 6 can be completely accommodated inside the placement space 3 in the assembled state.

[0040] like Figure 3 , Fig. 9 As shown, the desktop assembly 4 rotates to the second position, that is, the edge of the desktop assembly 4 corresponds to the placement space 3 between the two table legs 2. At this time, a human body can sit on the seat 2 in a posture facing the edge of the desktop assembly 4, so that the legs of the human body can be extended into the interior of the placement space 3, thereby improving the riding comfort of the human body.

[0041] The other parts of this embodiment are the same as those of Embodiment 1, and thus will not be described in detail.

[0045] Further, such as Figure 5-Figure 7 As shown, an elastic rotation limiter 5 is provided between the desktop bracket 1 and the desktop assembly 4, and the elastic rotation limiter 5 is used to limit the rotation angle of the desktop assembly 4. The elastic rotation limiter 5 is used to limit the rotation interval angle of the desktop assembly 4 between the first position and the second position each time. When the desktop assembly 4 rotates to the first position or the second position, the elastic rotation limiter 5 locks the desktop assembly 4, so that the desktop assembly 4 is fixed without unlocking and external force, thereby ensuring the stability of the desktop assembly 4. When the desktop assembly 4 needs to be rotated, the elastic rotation limiter 5 is unlocked, and the desktop assembly 4 can be rotated at this time to achieve convenient switching of the desktop assembly 4 between the first position and the second position.

[0046] The other parts of this embodiment are the same as those of Embodiment 1, and thus will not be described in detail.

The bottom of the desktop 42 is provided with a connection pin, a connection buckle, etc. corresponding to the connection hole, the connection slot, etc., so that the desktop 42 can be easily installed on the top of the rotating frame 41.

[0053] Further, such as Fig.10 and Fig.11 As shown, the elastic rotation limiting device 5 includes a pull rod 51, a spring 52, and a limiting pin 53. The pull rod 51 is slidably arranged on the bottom surface of the desktop bracket 1 in the vertical direction. The outside of the pull rod 51 is provided with a spring 52 that contacts the bottom surface of the desktop assembly 4. The top end of the pull rod 51 is provided with a limiting pin 53 corresponding to the limiting hole.

[0054] When the desktop assembly 4 rotates to the position where the limiting hole on the ground corresponds to the limiting head 53, the limiting head 53 is inserted into the limiting hole and engaged with the limiting hole under the action of the spring 52, thereby limiting the desktop assembly 4 from continuing to rotate, that is, limiting the rotation interval angle of the desktop assembly 4 each time. When the desktop assembly 4 needs to be further rotated, the pull rod 51 is pulled downward, the spring 52 is compressed, the limiting head 53 is disengaged from the limiting hole, and the desktop assembly 4 can continue to rotate by applying a rotational external force to the desktop assembly 4.

[0055] The other parts of this embodiment are the same as those of Embodiment 1 or 2, and thus will not be described in detail.
