Abstract

The invention discloses a deformable sofa bed. The deformable sofa bed comprises a pedestal; the pedestal is composed of a fixed pedestal and a movable pedestal; the fixed pedestal is composed of a supporting frame; the movable pedestal is composed of a supporting platform; the side surfaces of the supporting platform are surrounded by the supporting frame; adjacent surfaces of the supporting frame with the supporting platform are connected with slide rails; the slide rails are arranged in parallel with a moving direction of the movable pedestal; armrests are fixed on the left side and the right side of the pedestal; a backrest is connected with the back side of the pedestal via hinge connection; the backrest is divided into two layers, a front backrest and a back backrest; the left-right width of the front backrest is equal to that of the back backrest; the front backrest is connected with the back backrest via hinge connection; the surface of the supporting platform is provided with a cushion; the left side and the right side of the cushion are pressed firmly against the armrests on the two sides; and the back side of the cushion is pressed firmly against the backrest. The deformable sofa bed is light, is small in size, and is simple in structure; transformation between a seat state and a bed state is realized easily; complex operation is not needed; the parts are relatively light; and deformation is easy to realize.

Example Embodiment

[0014] Combine Figure 1 to Figure 4 To illustrate the specific embodiment of the present invention, a deformable sofa bed includes a base, the base is composed of a fixed base 1 and a mobile base 2, the fixed base 1 is formed with a support frame 3, and the mobile base 2 is formed with a support 4, The supporting frame 3 surrounds the side surface of the supporting table 4, and a sliding rail 5 is connected between the supporting frame 3 and the adjacent surface of the supporting table 4. The sliding rails 5 are arranged in parallel along the moving direction of the moving base. The left and right sides of the base are fixed with handrails 6 A backrest is hinged on the rear side. The backrest is double-layered, which is divided into a front backrest 7 and a rear backrest 8. The front backrest 7 and the rear backrest 8 have the same width in the left-right direction and are hingedly connected. The upper surface of the support platform 4 is laid There is a seat cushion 9, the left and right sides of the seat cushion 9 are in close contact with the armrests 6 on both sides, and the rear side of the seat cushion 9 is in close contact with the backrest.
[0015] More than one Velcro 10 is fixed on the back of the cushion 9, the veneer is a hook surface, and the surface of the support 4 is covered with fluffy cloth.
[0016] The width of the seat cushion 9 in the left-right direction is the same as the width of the front back 7 or the rear back 8.
[0017] The seat cushion 9, the front backrest 7 and the rear backrest 8 have the same thickness.
[0018] The deformation process is as follows: first remove the seat cushion 9, then pull out the mobile base 2, and then turn the front backrest 7 upwards by 180°, so that the front backrest 7 and the rear backrest 8 are on the same plane, and then the front backrest 7 Fold the backrest 8 forward by 90° and lay it on the base, and finally lay the cushion 9 on the mobile base 2 to complete the deformation.
