Description
Technical Field
The utility model relates to an anti-shake structure of a sofa; in particular to the field of posture fixing measures of folding seats or deformable functional sofas.
Background
Functional sofas, also known as deformable sofas; for the sofa, the user can meet the requirements of different use scenes by adjusting different sitting postures. The use scene through functional sofa distinguishes, generally divide into, the position of sitting: the backrest linkage mechanism and the leg stretching mechanism are in a furled state, and the sofa is in a state of a common sofa, so that the requirement of a user for sitting or half lying is met, and particularly, the backrest linkage mechanism is in a nearly vertical state at the moment. TV position in the sitting position, the leg extension mechanism is deployed so that it provides sufficient support to the user's legs while the back linkage remains stationary or topples slightly. Lying posture: in the state of the TV posture, the backrest linkage mechanism is inclined, and other mechanisms of the sofa, particularly the leg extension mechanism and the seat frame supporting mechanism of the sofa, are translated towards the opposite direction of the back linkage mechanism through the suspension translation mechanism, so that the inclined backrest linkage mechanism cannot be directly moved backwards, and the aim of zero leaning against the wall is achieved, and at the moment, the backrest linkage mechanism of the sofa is nearly in a horizontal state. Therefore, in the process of changing any posture of the sofa, the backrest linkage mechanism and the leg stretching mechanism always participate in the deformation process and make a large posture change.
The functional sofa at least has three postures of sitting posture, TV posture and lying posture, and the adjustment of the sofa posture is formed by the linkage of the mechanisms which are mutually related, in the process, the backrest linkage mechanism is used as the main supporting force of the back of a user, and particularly, the backrest linkage mechanism supports at least 1/3 weight of the user in the states of sitting posture, TV posture and the like; the leg extension mechanism supports the user's legs in a variety of positions. Therefore, the force for adjusting any action of the user is applied to the backrest linkage mechanism and the leg stretching mechanism, and if the measures are lacked, the backrest linkage mechanism and the leg stretching mechanism can shake along with the change of the posture of the user under the action of the force, so that the use comfort of the sofa is reduced.
In the prior art, the anti-shake after the posture of the sofa is changed is mainly carried out by adopting the modes of bushing limiting, propping against a connecting rod and the like. For example, as shown in fig. 1, patent No. 2013200403766, a multi-point limiting device for movable seats, discloses a measure for limiting and leaning against a link rod by inserting a bushing at a designed position, so that the sofa has a better anti-shake capability in a folded state (as shown in fig. 1).
However, the above structure also has some problems:
firstly, the lining is mostly made of nylon or engineering plastics, and due to long-term repeated stress, the materials have the problems of deformation, abrasion, cracking and the like after long-term use, so that after long-term use, the structure loses the anti-shaking function, and the backrest mechanism gradually generates frame amount and finally shakes.
Secondly, in the production process, holes need to be formed in the rest of the rods and the plates of the sofa and the bushings need to be installed in the holes, the rods and the plates of the functional sofa are complex to assemble, the process of installing the bushings undoubtedly increases the assembly difficulty of the functional sofa and reduces the production efficiency, the whole production cost is increased, and even the problems of assembly errors and the like can be caused. Once the sofa is assembled, the bushings inserted into the sofa frame and panels are also difficult to replace, which in turn invisibly increases the maintenance costs for the functional sofa at a later time.
The above-mentioned problems limit the role of the backrest mechanism in the functional sofa, and also limit the further development of the functional sofa. Therefore, the conventional anti-shaking structure of the sofa has various inconveniences and problems as described above.
