The motion principle of the present embodiment is：Motor push rod:50, which slide drive lifting pedestal motion guiding left and right sides, is joined
It is dynamic.During initial position, lifting frame 67 is in contact with welded connections 68（Figure 11）, motor push rod 50 toward recovery, so as to drive with
The connected welded connections 68 of motor push rod 50 rotates, and the drive of welded connections 68 is enclosed on adjustable connecting piece 69 therein and transported
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
Motion, the rear installed part 6 being fixed on old man's chair frame installing plate 4 and old man's chair frame installing plate 4 while is moved；Old man's chair
Mounting bracket 8, the 3rd raising connector 13, the old-man chair foot lever 3 of leg bridgeware 15 and the 3rd enter frame installing plate 4 drives simultaneously after
Row motion, rear mounting bracket 8 drive backrest conversion connector 9 to rotate, and leg bridgeware 15 drives the He of the 4th old-man chair foot lever 16
Old-man chair connecting rod 7 is moved, and thus drives the motion of leg.In this case, by Action of Gravity Field, 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 the front and rear conversion remains stationary of connector 12；In motor
Push rod 50 constantly toward reclaim during, old man's chair frame installing plate 4 is moved rearwards, 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 the 3rd raising connector 13
Extending apparatus is achieved that the process of the state from Fig. 1 to Fig. 2.
Motor push rod 50 continues to drive the second raising connector 11 to rotate toward recovery, the 3rd raising connector 13 afterwards, 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 spacing 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, so
Old-man chair mechanical extending device is achieved that the process of the motion state from Fig. 2 to Fig. 3.Conversely, travelled forward in motor push rod 50
Until lifting frame 67 contacts with welded connections 68 in the 6th phase section 51（See Figure 11）During, 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 Figure 11 original state, when motor push rod 50 moves forward, lifting pedestal passes through the 12nd rotating shaft 37
Lifting square frame 66 and the motion upwards around the shaft of lifting linking member 36 being connected to the 15th rotating shaft 40 on chassis 65, make by the tenth
Three rotating shafts 38 and the 14th rotating shaft 39 are lifted with the lifting frame 67 that lifting square frame 66 and lifting linking member 36 are connected, and are fixed on lifting
The left and right sides of geo-stationary is kept together to be lifted 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 recovery, old-man chair mechanical extending device is just slowly decreased until lifting square frame 66
On spacing pad 57 contacted with chassis 65 in the 7th phase section 64, old-man chair mechanical extending device returns to initial sitting posture.
