Dynamic adjustable crankshaft drives the first sliding block 5-6 and the second sliding block 5-7 to slide up and down.Since the first articulated shaft and the second articulated shaft are set
It sets in the two sides of the first shaft part axis, therefore the glide direction of the first sliding block 5-6 and the second sliding block 5-7 on the contrary, realize in turn
One sliding block 5-6's and the second sliding block 5-7 staggeredly slides.
As shown in Fig. 1,2 and 6, leg lifting mechanism 7 includes that gaiter band 7-5 and third cut with scissors board group.It includes head and the tail that third, which cuts with scissors board group,
Successively it is hinged to the 9th hinge plate 7-1, the tenth hinge plate 7-2, the 11st hinge plate 7-3 and the 12nd hinge plate 7-4 group of parallelogram
At.The 9th hinge plate 7-1 and chair body 1 being vertically arranged are fixed.12nd hinge plate 7-11 is located at the downside of the tenth hinge plate 7-2.Tenth
Two gaiter band 7-5 are fixed on one hinge plate 7-3.Gaiter is fixed with hook surface velcro, the fixed hairiness of the other end with one end of 7-5
Face velcro.The shank of user is lived with 7-5 ring with gaiter and connects velcro, the shank of user and the 11st can be cut with scissors
Plate 7-3 is fixed together.Plate 7-3's cut with scissors in 9th hinge plate 7-1, the articulated shaft of the tenth hinge plate 7-2 and the tenth hinge plate 7-2, the 11st
The spacing of articulated shaft is equal to 400mm.The spacing of 400mm is similar to the length of National People's Congress's leg.Third is enabled to cut with scissors board group maximum journey
The simulation human body of degree lifts the movement of leg when sitting up straight.Due to the 9th hinge plate 7-1, the tenth hinge plate 7-2, the 11st hinge plate 7-3 and the
12 hinge plate 7-4 constitute parallelogram.Therefore the 11st hinge plate 7-3 moment and the 9th hinge plate 7-1 are horizontal, that is, keep vertical shape
State.
There are two leg lifting mechanism 7 is total；The middle part of 12nd hinge plate 7-4 and two fourth link 5-8 in two leg lifting mechanisms 7
That end far from adjustable crankshaft is respectively articulated with.The adjustable crankshaft of rotation drives the 12nd hinge plate 7-4 in two leg lifting mechanisms 7 reciprocal
Rotation.Since the two sides of the first shaft part axis are arranged in third articulated shaft and the 4th articulated shaft, therefore the tenth in two leg lifting mechanisms 7
The rotation direction of two hinge plate 7-4 on the contrary, realize the effect that user's two legs alternately lift in turn.Two piece of the 12nd hinge plate 7-
4 using horizontality as lower pole.
As shown in Figure 1,2 and 3, arm drawing mechanism 6 includes rope 6-1, first pulley 6-2, second pulley 6-3, support
Column 6-4, handle 6-5 and adjusting electric pushrod 6-6.Two first pulley 6-2 of coaxial arrangement are supported on the top of riser.
Top of the bottom end of two support column 6-4 with backboard 3 is fixed.Two second pulley 6-3 of coaxial arrangement are supported on respectively
The top of two support column 6-4.Two shells for adjusting electric pushrod 6-6 and the first sliding block 5-6, the second sliding block 5-7 are solid respectively
It is fixed；The push-off pin of two adjusting electric pushrod 6-6 is arranged upward, and fixes respectively with one end of two rope 6-1.Two ropes
The other end of rope 6-1 is fixed respectively with two handle 6-5.Two rope 6-1 bypass two first pulley 6-2 respectively, and respectively
Around two second pulley 6-3.The the first sliding block 5-6 staggeredly slided and the second sliding block 5-7 can pull two rope 6-1 to interlock
Movement, so that the crisscross motion of two handle 6-5, realizes that user is held in two on two handle 6-5 on hand respectively
Interlock down extensional motion.
One of handle 6-5 is moved in the state of highest point, and the 12nd hinge plate of the same side is located at handle 6-5
7-4 is in a horizontal state.
The working principle of the utility model, which is divided into sitting idly to temper principle, aiding upright principle and stand, tempers principle.
Sitting idly, it is specific as follows to temper principle:
User takes seating pad 2, and cuts with scissors the gaiter on plate 7-3 with two piece the 11st and pinion user's respectively with 7-5
Both legs.User with the hands holds two handle 6-5 respectively.Motor 5-1 starting, drives adjustable crank rotation.Adjustable crankshaft
It rotates while the first sliding block 5-6 and the second sliding block 5-7 being driven to reciprocatingly slide, drive two piece of the 12nd hinge plate 7-4 reciprocating rotation.By
In the glide direction of the first sliding block 5-6 and the second sliding block 5-7 on the contrary, therefore user is held in two on two handle 6-5 respectively
Lower staggeredly extensional motion on hand.Due to third connecting rod 5-5 and fourth link 5-8 rotation direction on the contrary, therefore the two legs of user
It lifts alternatively up and down.While one of handle 6-5 is moved upwards, the 12nd hinge plate of the same side is located at handle 6-5
7-4 is downwardly turned over.Avoid exercise in hand with foot the case where, substantially increase the effect of exercise.
Aiding upright principle is specific as follows:
User takes seating pad 2, and guarantees that both legs are not pinioned by gaiter band 7-5.Standing electric pushrod 4-1 is retracted,
The spacing of sliding panel 4-2 and fixed plate 4-3 increases, and sliding panel 4-2 upward sliding, squab plate tilts upward fortune with fixed plate 4-3
It is dynamic.In the process of movement, the moment keeps vertical state to squab plate.And squab plate drives seating pad 2 to overturn, squab plate and cushion
2 angulations of plate are gradually increased.After squab plate and 2 angulations of seating pad reach 180 °, standing electric pushrod 4-1 stops retracting, this
When, on same perpendicular, user is completed from the movement for sitting on station for squab plate and seating pad 2.Due to supporting second pulley
The support column 6-4 of 6-3 is fixed in squab plate, therefore two second pulley 6-3 are moved with the movement of squab plate.User stands
During, the relative position of two second pulley 6-3 and user's both hands do not change.
Standing, it is specific as follows to temper principle:
After user is got up by aiding upright, two handle 6-5 are with the hands held respectively.Motor 5-1 starting, drives adjustable
Crank rotation.The rotation of adjustable crankshaft drives the first sliding block 5-6 and the second sliding block 5-7 to reciprocatingly slide simultaneously.Due to the first sliding block
The glide direction of 5-6 and the second sliding block 5-7 on the contrary, realize two hands that user is held in respectively on two handle 6-5 in turn
Interlock extensional motion up and down.Since both legs are not pinioned by gaiter band 7-5, therefore the movement of leg lifting mechanism 7 does not generate user
It influences.
