Description

Technical Field

[0001] The present application relates to the technical field of sofas, and in particular to a multi-person interactive rocking sofa. Background Art

[0002] With the improvement of living standards, the advantages of sofas that are only soft enough and comfortable to sit on are no longer satisfactory. In this regard, the State Intellectual Property Office of China announced a utility model patent with announcement number CN2834310Y on November 8, 2006, which discloses a rocking sofa that is not only comfortable to sit on but also can rock forward and backward.

[0003] With the further development of society, some people feel that the sofa can not meet their needs if it can only move forward and backward. The State Intellectual Property Office of China announced a utility model patent with the announcement number CN201899173U on July 20, 2011, which discloses a rocking sofa similar to a tumbler, which can rock in all directions.

[0004] However, the above sofas all have the following problems: they are limited to single-person use, cannot be used by multiple people, and the swing amplitude cannot be adjusted. Utility Model Content

[0005] The purpose of the present application is to provide a multi-person interactive rocking sofa, in order to solve the problem that the rocking sofa can only be used by one person and the rocking amplitude cannot be adjusted.

[0006] The present application provides a multi-person interactive rocking sofa, which adopts the following technical solution: a multi-person interactive rocking sofa, comprising a chassis, a support frame, and a seat frame, wherein the support frame is fixedly connected to the chassis, the seat frame is hinged to a side of the support frame away from the chassis, an adjustment mechanism for adjusting the swing amplitude of the seat frame is provided between the seat frame and the chassis, one end of the adjustment mechanism is hinged to the seat frame, and the other end of the adjustment mechanism is hinged to the chassis.

[0007] This technical solution realizes the rotation of the seat frame around the hinge of the seat frame and the support frame through the hinge of the seat frame and the support frame, thereby realizing the swing of the multi-person interactive rocking sofa. Since the multi-person interactive rocking sofa is not fixed on the ground, the larger chassis is used to keep the sofa stable and not overturned, ensuring the safety of users using the multi-person interactive rocking sofa. The support frame is used to support the weight of the seat frame and the user. The seat frame is used to realize the rocking function of the multi-person interactive rocking sofa similar to a seesaw. The decorative parts are used to wrap the support frame and the seat frame to make the appearance more beautiful, making the multi-person interactive rocking sofa more like a sofa rather than a seesaw. The adjustment mechanism is used to adjust the swing degree of the seat frame, so that the sofa takes into account safety and fun during use. The absence of armrests facilitates the placement of the sofa and the user's straddling or sitting sideways, which is more convenient for users to use. Since the multi-person interactive rocking sofa is extremely sensitive to weight, it is not easy for the seat frame to remain stationary, which is not convenient for people to lie down or sit for a long time, thereby improving the utilization efficiency of the multi-person interactive rocking sofa.

[0008] Furthermore, the adjustment mechanism includes a coil spring and an adjustment bolt, one end of the coil spring is hinged to the end of the adjustment bolt close to the chassis, and the adjustment bolt is threadedly connected to the seat frame. By moving the adjustment bolt along the length direction, the stretched length of the coil spring is adjusted, thereby adjusting the tension of the coil spring on the seat frame, so that the adjustment mechanism can adjust the swing range of the seat frame. The coil spring has a longer service life.

[0009] Furthermore, the adjustment mechanism also includes a first buffer mechanism for buffering the swing speed of the seat frame, one end of the first buffer mechanism is hinged to the seat frame, and the other end of the first buffer mechanism is hinged to the chassis. The buffer mechanism is used to buffer the swing speed of the seat frame to make people sit more comfortably.

[0010] Furthermore, the first buffer mechanism includes an elastic body, which is formed by at least two rotating bodies with different diameters connected in series. The shape of the elastic body is a plurality of rotating bodies with different diameters connected in series, and the rotating body with a smaller diameter is compressed first, and then compressed step by step according to the diameter of the rotating body. In this way, during use, people will not feel the buffering of the elastic body, and people will feel more comfortable.

[0011] Furthermore, the first buffer mechanism also includes a limiter, one end of which is hinged to the chassis, the other end of which is hinged to the seat frame, and the elastic body is sleeved on the outside of the movable end of the limiter. The limiter can limit the swing range of the seat frame. The gas spring can linearly adjust the elastic force, and the buffering effect is better. The gas spring and the elastic body are compressed at the same time. Before the gas spring reaches the compression limit, the elastic body is first compressed to the limit to protect the gas spring from collision inside the cylinder body; the gas spring also has a locking function. When the gas spring is locked, the gas spring cannot be compressed, and the gas spring will support the seat frame. At this time, the seat frame loses its swinging function and becomes a normal sofa.

[0012] Furthermore, a second buffer mechanism for buffering the swing speed of the seat frame is provided between the seat frame and the support frame. The second buffer mechanism is a redundant mechanism for buffering the swing speed of the seat frame, and has a better buffering effect. The multi-person interactive swinging sofa has a longer service life.

[0013] Furthermore, the second buffer mechanism is a gas spring, one end of which is hinged to the seat frame, and the other end of which is hinged to the support frame. The gas spring can linearly adjust the elastic force, and has a better buffering effect.

[0014] Furthermore, the support frame includes a connecting frame, a truss and four supporting columns, one end of each supporting column is fixed to the chassis, the other end of each supporting column is fixed to the truss, the connecting frame is fixed on the truss, and the connecting frame is hinged to the seat frame. The truss structure can disperse the pressure, making the support frame more solid and having a longer service life.

[0015] Furthermore, the adjustment mechanism and the first buffer mechanism are located between the connecting frame and the chassis, and are located on the inner side of the four support columns, and the second buffer mechanism is located on the outer side of the four support columns; the length direction of the chassis is the same as the swing direction of the seat frame; the chassis has a double-layer structure design, and the bottom layer of the chassis is partially hollowed out. The coil spring, limiter, and gas spring are close to the center of rotation, so that the bottom is in a state of being nearly suspended, which enhances the appearance. The length direction of the chassis is the same as the swing direction of the seat frame. When swinging, the center of gravity is always located in the chassis to prevent the multi-person interactive swinging sofa from overturning. The chassis has a double-layer structure design, and the bottom layer is partially hollowed out, which is lighter and convenient for the installation and transportation of the multi-person interactive swinging sofa. The friction between the chassis and the ground is greater. When in use, the multi-person interactive swinging sofa will not move due to swinging.

[0016] Furthermore, there are two adjustment mechanisms, one adjustment mechanism is located on one of the two opposite sides of the hinge between the support frame and the seat frame, and the other adjustment mechanism is located on the other side of the hinge between the support frame and the seat frame; there are four first buffer mechanisms, two first buffer mechanisms are located on one of the two opposite sides of the hinge between the support frame and the seat frame, and the other two first buffer mechanisms are located on the other side of the hinge between the support frame and the seat frame; there are two second buffer mechanisms, one second buffer mechanism is located on one of the two opposite sides of the hinge between the support frame and the seat frame, and the other second buffer mechanism is located on the other side of the hinge between the support frame and the seat frame; one adjustment mechanism is located in the middle of the two first buffer mechanisms located on the same side. The adjustment mechanism, the first buffer mechanism, and the second buffer mechanism are symmetrically arranged about the hinge between the support frame and the seat frame, and the first buffer mechanism is symmetrically arranged about the adjustment mechanism, the adjustment mechanism has a better adjustment effect on the swing amplitude of the seat frame, the first buffer mechanism and the second buffer mechanism have a better buffering effect, and the use and installation are more convenient and more beautiful.

[0017] In summary, the present application includes at least one of the following beneficial technical effects:

[0018] 1. It can be used by multiple people, which makes it more interesting. 2. The adjustment mechanism can adjust the swing degree of the seat frame, which is safer. 3. The buffer mechanism is redundantly set, which has better buffering effect and longer service life. 4. The structure is simple, and the bottom layer of the chassis is partially hollowed out to reduce the weight. 5. It is more beautiful overall. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The embodiment of the present application discloses a multi-person interactive rocking sofa.

[0028] Reference Figure 1 ,

[0029] The implementation principle of a multi-person interactive rocking sofa in the present application embodiment is as follows:

[0030] like Figure 1 As shown, a multi-person interactive rocking sofa includes a chassis 1 located at the bottom, the upper side of the chassis 1 is fixed to the lower ends of four support columns 23, the upper ends of the support columns 23 are fixed with trusses 22, the trusses 22 are fixedly connected to a connecting frame 21, and the front and rear ends of the connecting frame 21 are respectively hinged to the front and rear sides of the seat frame 3.

[0031] like Figure 1 As shown, the seat frame 3 is composed of two layers of rectangular frames 31 with different lengths in the left-right direction and the same width in the front-to-back direction. The length of the rectangular frame 31 is greater than the width to accommodate more users sitting on the multi-person interactive rocking sofa. The length of the upper rectangular frame 31 is greater than the lower rectangular frame 31, and the corresponding vertices of the two layers of rectangular frames 31 are fixedly connected by a first rectangular tube 32. The upper rectangular frame 31 is connected to two second rectangular tubes 33 extending in the front-to-back direction, and the second rectangular tubes 33 are located on both sides of the connecting frame. An adjustment mechanism 4 is connected between the second rectangular tube 33 and the chassis 1. The adjustment mechanism 4 includes an adjustment bolt 42 and a coil spring 41.

[0032] like Figure 2 and Figure 3 As shown, an adjusting bolt 41 is screwed at the midpoint of the second rectangular tube 33, the upper end of the coil spring 41 is hinged to the bottom of the adjusting bolt 41, and the lower end of the coil spring 41 is hinged to the upper side of the chassis 1. The first buffer mechanism 43 is respectively provided on the front and rear sides of the coil spring 41, and the first buffer mechanism 43 includes a limiter 432, which is a gas spring, the bottom of the gas spring is hinged to the chassis 1, and the movable end of the movable rod of the gas spring is hinged to the second rectangular tube 33. The movable rod of the gas spring is sleeved with an elastic body 431, and the elastic body 431 is composed of three rotating bodies 4311 connected in series from bottom to top, and the diameters of the two rotating bodies 4311 at the bottom are smaller than the diameters of the two rotating bodies 4311 at the top, and the diameters of the two rotating bodies 4311 at the bottom are the same.

[0033] like Figure 1 and Figure 4 As shown, the connecting frame 21 is a rectangular parallelepiped frame structure. The length direction of the connecting frame 21 is perpendicular to the length direction of the rectangular frame 31.

[0034] like Figure 1 and Figure 4 As shown, the bottom of the truss 22 is an octagon, and the two opposite sides of the truss 22 coincide with the two shorter edges below the connecting frame 21. Of the remaining four vertices of the octagon, the two vertices on the left are connected to the longer left edge of the connecting frame 21 by the third rectangular tube 221, and the two points on the right are connected to the longer right edge of the connecting frame 21 by the third rectangular tube 221. The third rectangular tube 221 is also a part of the truss 22. The whole formed by the truss 22 and the support column 23 is similar to a truss bridge, which is used to disperse the pressure of the seat frame 3 on the connecting frame 21 and prevent the connecting frame 21 from bending and deforming.
