In the lifting pedestal of the embodiment of the present invention, lifting box 66 is connected by the 12nd shaft 37 with chassis 65, is risen Drop frame 67 is connected by the 14th shaft 39 with lifting box 66, and lifting linking member 36 passes through the 13rd shaft the 38, the 15th respectively Shaft 40 is connected with lifting frame 67, chassis 65;Welded connections 68 is connected by the 16th shaft 41 with lifting frame 67, is adjusted The square tube of connector 69 is inserted in the square tube of welded connections 68, is achieved in the function of adjustment width.
Left and right sides component is consolidated by the 7th mounting hole 42, the 8th mounting hole 43, the 9th mounting hole 44, the tenth mounting hole 45 It is scheduled on lifting pedestal, 18 one end of bolt connection piece is connected by the 17th shaft 46 with adjustable connecting piece 69, and the other end leads to It crosses first rotating shaft 22 with left and right sides component to be connected, realizes that lifting pedestal drives the function of left and right sides movement;Old-man chair mechanical device Comprising electric device, electric device is rotatablely connected by the tenth eighth-turn axis 48 with welded connections 68, and electric device passes through the tenth Nine shafts 49 are mounted on chassis 65, and electric device includes motor 47, motor push rod 50.
The motion principle of the present embodiment is:Motor push rod:50, which slide drive lifting pedestal movement guiding left and right sides, is joined It is dynamic.During initial position, lifting frame 67 is in contact (Figure 11) with welded connections 68, motor push rod 50 toward recycling, so as to driving and The connected welded connections 68 of motor push rod 50 rotates, and the drive of welded connections 68 is sleeved on adjustable connecting piece 69 therein and transports Dynamic, adjustable connecting piece 69 drives the old man's chair frame installing plate 4 being fixedly linked with preceding installed part 5 further through bolt connection piece 18 Movement, the rear installed part 6 being fixed on old man's chair frame installing plate 4 move simultaneously with old man's chair frame installing plate 4;Old man's chair Frame installing plate 4 simultaneously drive after mounting bracket 8, third raising connector 13, leg bridgeware 15 and third old-man chair foot lever 3 into Row movement, rear mounting bracket 8 drive backrest conversion connector 9 to rotate, and leg bridgeware 15 drives 16 He of the 4th old-man chair foot lever Old-man chair connecting rod 7 moves, and thus drives the movement of leg.In this case, by gravity, the first raising connector 14 with Second limiting bush 54 is tangent in the first phase section 53, and the second raising connector 11 is with old man's armrest of seat installing plate 10 in the 5th phase Section 63 is tangent, the first raising connector 14, the second raising connector 11 and front and rear conversion 12 remains stationary of connector;In motor Push rod 50 constantly toward recycle during, old man's chair frame installing plate 4 moves backward, and leg is stretched forward, to be exercised to first When the first phase section 53 is tangent, leg is fully deployed, such old-man chair machinery for limiting bush 52 and third raising connector 13 Extending apparatus is achieved that the process of the state from Fig. 1 to Fig. 2.
Motor push rod 50 continues toward recycling later, and third raising connector 13 drives the second raising connector 11 to rotate, leg Portion's bridgeware 15 drives the first raising connector 14 to rotate, and front and rear conversion connector 12 is by the first raising connector 14 and second Connector 11 is risen to drive simultaneously, originally with the second limiting bush 54 in the first tangent raising connector 14 of the second phase section 55 and The second raising connector 11 tangent in the 5th phase section 63 is lifted up leaving limiting with old man's armrest of seat installing plate 10, until When the second raising connector 11 and old man's armrest of seat installing plate 10 tangent at third phase section 56, backrest is toppled over completely, in this way Old-man chair mechanical extending device is achieved that the process of the motion state from Fig. 2 to Fig. 3.Conversely, it travels forward in motor push rod 50 During lifting frame 67 contacts (see Figure 11) with welded connections 68 in the 6th phase section 51, old-man chair mechanical stretching dress Putting successively realizes the process that leg is collapsed from Fig. 2 to Fig. 1 again from Fig. 3 to Fig. 2.
Under the original state of Figure 11, when motor push rod 50 moves forward, lifting pedestal passes through the 12nd shaft 37 The lifting box 66 and lifting linking member 36 being connected on chassis 65 with the 15th shaft 40 move upwards around the shaft, make by the tenth Three shafts 38 and the 14th shaft 39 are lifted with the lifting frame 67 that lifting box 66 and lifting linking member 36 are connected, and are fixed on lifting Opposing stationary left and right sides is kept to be lifted together on frame 67, such old-man chair mechanical extending device is achieved that from Fig. 1 to Fig. 4 The process of state.Conversely, when motor push rod 50 is toward recycling, old-man chair mechanical extending device is just slowly decreased until lifting box 66 On plastics limiting pad 57 contacted with chassis 65 in the 7th phase section 64, old-man chair mechanical extending device returns to initial sitting posture.
The present embodiment redesigns component the Nomenclature Composition and Structure of Complexes, extra intermediate connection is eliminated, by left and right sides Component is connected directly with lifting pedestal, simplifies mounting means, improves efficiency, has been obviously improved safety and comfortable Property.
Embodiment adds backrest limitings to design, and ensure that the backrest of old-man chair sofa sitting posture state and raising process is steady It is qualitative, safety and comfort.
The present embodiment is designed using flanging, and general zerowall sofas yoke is directly assembled with sofa yoke, without dividing Into multiple assemblies, installation effectiveness is high.
Standard of the present invention is convenient, safety and firmness, the simple deformation or equivalent transformation of every present invention, it is considered that fall into Protection scope of the present invention.
