Drawings
Fig. 1 is a schematic view of a functional sofa structure with extendable legs near the wall according to the present embodiment;
fig. 2 is a schematic view of the functional sofa structure with extendable legs near the wall according to the embodiment in an extended state;
fig. 3 is a schematic view of the extensible functional sofa with zero-wall legs according to the present embodiment in a folded state.
Detailed Description
The extendable leg functional sofa structure of the zero-side wall will be further described with reference to fig. 1 to 3.
The utility model provides a function sofa mechanism that shank that zero is leaned on wall can extend which characterized by: comprises an underframe 1, a supporting plate 3, a rocker component and a stretching component.
Specifically, the rocker assembly comprises a front rocker 21 and a rear rocker 22, and the lower end of the front rocker 21 and the lower end of the rear rocker 22 are respectively hinged to the front side and the rear side of the underframe 1. The front position of the supporting plate 3 is hinged with the upper end of the front rocker 21 through a connecting plate 31, and the rear position of the supporting plate 3 is hinged with the upper end of the rear rocker 22; in this embodiment, the support plate 3 is used for mounting the seat assembly in the functional sofa. The extension assembly comprises a first link 41, a second link 42, a third link 43, a fourth link 44, a fifth link 46, a sixth link 47, a drive rod 45 and a foot pull 48; as shown in fig. 1, the rear end of the first link 41 is hinged to the front end of the support plate 3, the front end of the first link 41 is hinged to the rear end of the second link 42, the front end of the second link 42 is hinged to the front end of the foot rest, the rear end of the third link 43 is hinged to the rear end of the support plate 3, the front end of the third link 43 is hinged to the rear end of the fourth link 44, the front end of the fourth link 44 is hinged to the rear end of the foot rest, the front end of the drive rod 45 is hinged to the front end of the third link 43, the rear end of the drive rod 45 is hinged to the lower end of the fifth link 46, the middle of the fifth link 46 is hinged to the support plate 3, the upper end of the fifth link 46 is hinged to the rear end of the sixth link 47, and the front end of the sixth link 47 is hinged to the middle of the front rocker 21.
Based on the above structure, the electric push rod is installed on the chassis 1, and the push rod of the electric push rod is connected with the driving rod 45 through a motor pipe, so that when the electric push rod extends, the driving rod 45 pushes the first connecting rod 41, the second connecting rod 42, the third connecting rod 43 and the fourth connecting rod 44 forwards, so that the extending assembly achieves the extending effect; when the extension assembly extends, the assembly structure between the sixth connecting rod 47 and the front rocker 21, the fifth connecting rod 46 and the support plate 3 can drive the support plate 3 to move forwards, so that the back of the functional sofa is placed against the wall and cannot interfere with the normal extension function of the functional sofa, the functional sofa can be conveniently placed, and the space after the functional sofa is placed is saved.
The first link 41 has a first pin 51 for supporting the fourth link 44, and the second link 42 has a second pin 5252 for supporting the fourth link 44. When the spreader assembly is in the deployed state, the upper side of the fourth link 44 abuts against the first pin 51 to keep the entire spreader assembly deployed stable; the underside of the fourth link 44 abuts the second pin 52 when the spreader assembly is in the retracted state to provide stability to the spreader assembly when collapsed.
The second pin rod 52 is hinged with a leg drag rod 6, and the leg drag rod 6 is simultaneously hinged with the fourth connecting rod 44. The leg rest 6 can be used to support the legs of the user when the extension assembly is in the extended position to improve the comfort of the user lying.
The first pin rod 51 and the second pin rod 52 are sleeved with sleeves, and the sleeves can rotate relative to the first pin rod 51 and the second pin rod 52. During the folding and unfolding processes, the fourth link 44 will be in friction movement against the first pin 51 or the second pin 52, so the sleeve can reduce the friction between the fourth link 44 and the first pin 51 and the second pin 52.
The supporting plate 3 is provided with an outward-turning mounting part 32, the mounting part 32 is used for assembling the supporting plate 3 and other parts in the functional sofa, and meanwhile, the mounting part 32 and the supporting plate 3 are of an integrated structure, so that the structure is simplified, and the structural stability can be improved.
In the present embodiment, the hinge joints between the components are realized by pins.
