Example 1, as shown in reference to figures 1 to 3,
the elastic sofa 100 provided in this embodiment, as shown in fig. 1, includes a sofa body 110 and an elastic mechanism 120, wherein the elastic mechanism 120 is disposed at the bottom of the sofa body 110 for maintaining the elasticity of the sofa body 110.
The elastic mechanism 120, as shown in fig. 2 and 3, includes a fixed frame 121, a supporting frame 122, a first movable arm 123, a second movable arm 124, a connecting rod 125, and an elastic contraction rod 126. The fixing frame 121 is fixedly disposed on the sidewall of the sofa body 110. The fixing frame 121 is a frame structure, and includes a first beam 121a, a second beam 121b, a vertical beam 121c, and a bottom plate 121 d. The first cross member 121a and the second cross member 121b are parallel to each other, and the vertical member 121c is vertically disposed between the first cross member 121a and the second cross member 121 b. In the present embodiment, two vertical beams 121c are provided near the ends of the first and second lateral beams 121a and 121b, respectively. The bottom plate 121d is perpendicular to the plane of the first cross member 121a and the vertical member 121 c.
The supporting frame 122 is fixedly connected to a side of the fixing frame 121 far away from the ground, in this embodiment, the supporting frame 122 is fixedly connected to the first beam 121a of the fixing frame 121. The supporting frame 122 is rectangular, and the plane of the supporting frame 122 is perpendicular to the plane of the fixing frame 121.
The first movable arm 123 is hinged to one end of the supporting frame 122 away from the fixed frame 121, and the first movable arm 123 can move up and down relative to the plane where the supporting frame 122 is located by taking the hinged end as a center. And the second movable arm 124 is hinged to one side of the fixed frame 121 close to the ground, that is, the second movable arm 124 is hinged to the second cross beam 121b, and a second elastic piece 124a is arranged at the bottom of the second movable arm 124. That is, the second elastic element 124a is disposed between the second movable arm 124 and the bottom plate 121 d. The second movable arm 124 can move up and down about the hinged end with respect to a horizontal plane. The projection of the second movable arm 124 on the horizontal plane is an isosceles triangle. The vertical distance between the vertex of the first movable arm 123 and the vertex of the second movable arm 124 and the plane of the fixed frame 121 are equal.
The connecting rod 125 is disposed between the first movable arm 123 and the second movable arm 124, and the connecting positions of the connecting rod 125 and the first movable arm 123 and the second movable arm 124 are the farthest ends of the first movable arm 123 and the second movable arm 124 from the fixed frame 121. The connecting rod 125 is vertically disposed between the first movable arm 123 and the second movable arm 124. The length of the connecting rod 125 is smaller than the vertical distance between the supporting frame 122 and the second movable arm 124. When the projection of the second movable arm 124 on the horizontal plane is an isosceles triangle, the connecting rod 125 and the elastic contraction rod 126 are connected to the top corner of the second movable arm 124. Under the condition that the connecting rod 125 is not stressed, the second movable arm 124 is not in contact with the sofa body 110 and is in a suspended state. When the connecting rod 125 is pressed downward, the first movable arm 123 and the second movable arm 124 are moved downward.
The elastic contraction rod 126 is obliquely arranged between the support frame 122 and the second movable arm 124, an included angle between the elastic contraction rod 126 and a horizontal plane is 45-75 degrees, and in the embodiment, an included angle between the elastic contraction rod 126 and the horizontal plane is about 60 degrees. The elastic contraction rod 126 comprises a first rod 126a, a hollow sleeve 126b, a second rod 126c, a limiting ring 126d and a first elastic piece 126e, one end of the first rod 126a is hinged to one side, away from the fixed frame 121, of the second movable arm 124, the other end of the first rod 126a is fixedly connected to the hollow sleeve 126b, one end of the second rod 126c is embedded in the hollow sleeve 126b in a sliding mode, the other end of the second rod 126c is hinged to one side, away from the fixed frame 121, of the support frame 122, the limiting ring 126d is arranged at one end of the hollow sleeve 126b, and the first elastic piece 126e is sleeved on the hollow sleeve 126b and the second rod 126c and one end of the first elastic piece is in contact with the limiting ring 126 d.
When the connecting rod 125 is not under load, i.e. the sofa is not bearing load, the first elastic member 126e is located between the limiting ring 126d and the supporting frame 122, and is in a compressed state. When the connecting rod 125 is pressed downward, the end of the second movable arm 124 is driven to move downward, and the second elastic member 124a is compressed, and at the same time, the first rod 126a and the hollow sleeve 126b are driven to move in a direction away from the first elastic member 126e, so that the second rod 126c slides relative to the hollow sleeve 126b, and the distance between the limiting ring 126d and the supporting frame 122 is changed, so that the first elastic member 126e is in an extended state. When the pressure on the connecting rod 125 is removed, the second elastic member 124a recovers its shape, and the end of the second movable arm 124 is forced to move upward, so that the distance between the limiting ring 126d and the supporting frame 122 is shortened, and the first elastic member 126e is pressed to be in a compressed state.
In this embodiment, in order to improve the comfort of the bouncy sofa 100, an arc plate 130 is disposed above the bouncy mechanism 120, and the arc plate 130 contacts with one end of the link 125 away from the ground. The arcuate plate 130 compresses the link 125 as the sofa is loaded.
When a person sits and lies on the sofa, the elastic sofa 100 will press the connecting rod 125, so that the connecting rod 125 drives the first movable arm 123 and the second movable arm 124 to move downwards, press the second elastic element 124a, and simultaneously stretch the elastic contraction rod 126 to make it in an extended state; when a person leaves the sofa, the connecting rod 125 drives the first movable arm 123 and the second movable arm 124 to move upward under the restoring force of the second elastic member 124a, so that the sofa is deformed again. The vertical distance between the supporting frame 122 and the second movable arm 124 is changed when the elastic sofa 100 bears the load, and the first elastic piece 126e and the second elastic piece 124a are matched with each other, so that the problem of sofa collapse and deformation after long-term use is avoided.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
