Abstract

The utility model discloses a labor-saving changeable bed-chair for sitting and lying, which relates to sofas, beds or devices which can facilitate patients. A panel of the utility model can be divided into an upper plate, a middle plate and a lower plate, and the upper plate, the middle plate and the lower plate are connected by hinges. A rotary shaft which supports a base is arranged at a certain position (near the barycenter of a human body) between the middle point of the upper plate and the hinges, and the middle and lower plates are movably supported by the base or the upper plate. When users draw abdomen, the upper plate rotates around the rotary shaft and the positions of the middle and lower plates are changed accordingly. Since the barycenter moves little, the force needed by the change of postures is small and the users can change the sitting and lying postures with the strength of their own. At this time, the distance between the middle plate and the ground is reduced, which is convenient for getting on and down a bed and the utility model has the advantage of simple structure.

Description

The shift bed chair that crouches is sat in a kind of labour-saving
The shift bed chair that crouches is sat in a kind of labour-saving, relates to sofa, bed or makes things convenient for patient's equipment, particularly has the sick bed of skilled nursing facility and is applicable to weakling's chair.
Existing get up sit see hospital ward in a large number.It is made up of rocking bar, leading screw and a series of lever, the rotating shaft of the head of a bed, rotates around the rotating shaft of its termination with the backboard that drives bed surface to allow the user change seat prone position attitude.This bed, comparatively require great effort, and for ease of medical treatment, it is higher that bed surface is liftoff, falls down easily when the user gets in and out of bed user's lifting above the waist certain altitude by other people operation.Described multi-purpose bed as Chinese patent CN1146329A, CN2155845Y, CN2272278Y, CN2182612Y, CN2155845Y, CN2248554Y, all on existing hand-rail type sick bed basis, set up motor, hydraulic pressure and other reduction gearing mechanism, to realize that patient can control button voluntarily and change seat prone position attitude.Described sofa of Chinese patent CN99211575.2 etc. and for example.Their complex structures, reliability is low, the influence that is had a power failure easily, and user's bunk bed is still felt inconvenience.
The utility model is at above-mentioned each routine defective and disadvantage, disclose a kind of simple in structure, required driving force is less, only depend on user's oneself strength and other people the simple bed chair that helps just can change easily seat prone position attitude, the distance on this chair user buttocks and ground is little during than prone position when sitting posture, is convenient to about the user.
The shift bed chair that crouches is sat in labour-saving of the present utility model, form by panel and base, wherein panel is divided into three of upper plates, middle plate, lower plate, respectively by hinge in last, in down hinge link form as a whole, it is characterized in that: base has two pairs of fulcrums of primary and secondary at least, main fulcrum supports upper plate with rotating shaft mode, this rotating shaft is fixed on the mid point of upper plate to a certain position between the last middle hinge, middle plate can be supported by the inferior fulcrum on the base by the rocking bar of band rotating shaft, and lower plate can be by the rocking bar of being with rotating shaft by the push rod support of another time fulcrum of base or upper plate below.
The shift bed chair that crouches is sat in aforesaid labour-saving, and it is characterized in that: lower plate can be supported by another time fulcrum on the base by the mode of slide block chute.
The shift bed chair that crouches is sat in aforesaid labour-saving, form by panel and base, wherein panel is divided into three of upper plates, middle plate, lower plate, respectively by hinge in last, in down hinge link form as a whole, it is characterized in that: base has two pairs of fulcrums of primary and secondary at least, main fulcrum supports upper plate with rotating shaft mode, this rotating shaft is fixed on the mid point of upper plate to a certain position between the last middle hinge, middle plate can be supported by the inferior fulcrum on the base by the mode of slide block chute, and lower plate can be supported by the push rod of another time fulcrum of base or upper plate below by the rocking bar of band rotating shaft.
The shift bed chair that crouches is sat in aforesaid labour-saving, and it is characterized in that: lower plate can be supported by another time fulcrum on the base by the mode of slide block chute.
The shift bed chair that crouches is sat in aforesaid labour-saving, it is characterized in that: the distance of main fulcrum and last middle hinge axes is between 10~40 centimetres
The shift bed chair that crouches is sat in aforesaid labour-saving, it is characterized in that: panel and other movable member that links with it also can be provided with positioning and locking device.
This chair mainly is made of panel and base, panel can be divided into upper plate, middle plate, three of lower plates, bear user's head back of the body waist respectively, thigh, the weight of shank, three by hinge in last, in down hinge link form as a whole, it is characterized in that: base has the master at least, inferior two pairs of fulcrums, main fulcrum supports upper plate with rotating shaft mode, this rotating shaft is fixed on the mid point of upper plate to a certain position between the last middle hinge, this position is positioned near the person's of couching centre of body weight, difference according to user's height or center of gravity position, the distance of the axis of hinge is between 10~40cm in last, the fixing a pair of rotating shaft of going up in middle plate bottom, inferior fulcrum is fixed a pair of lower rotary shaft, and two countershafts are connected by a pair of rocking bar, plate can rotate around last rotating shaft in making, and middle plate and rocking bar together can be around the i.e. time fulcrum rotations of lower rotary shaft; Plate during inferior fulcrum can also support in the mode of slide block chute, when upper plate during around the rotation of main pivot shaft, the fixing slide block (chute) in middle plate bottom can slide during being fixed in base upper hopper chute (slide block), with the plan-position of definite middle plate correspondence.Upper plate is fixed with a pair of push rod that stretches out downwards near hinge one end in last, the terminal end with a pair of movable rocking bar of push rod links with rotating shaft mode, the other end of rocking bar links with the mode of rotating shaft and a certain fixing point of lower plate below, to determine the position at the corresponding place of lower plate; Lower plate also can be fixed a pair of slide block (chute), and they can slide to determine the correspondence position of lower plate in a pair of chute (slide block) on being fixed in base.The positioning and locking device that panel and other movable member that links with it also can be set up clamps or loosens, and plays the effect of location when the internal crucible chair is adjusted to desired location.The clamping and the relaxation state that are fixed on these positioning and locking devices on the base can be controlled by operating grip.
The utility model is because the fulcrum that will support the upper plate of the main weight of human body is arranged near the gravity center of human body, though the angle variation of human body is bigger when sitting the conversion of prone position attitude, center of gravity is constant substantially, and required work done is less, and driving force is also less; And the main backrest of user, stern, leg are exerted all one's strength, and the force is bigger from the distance of main pivot shaft, thereby required power more reduces.The movable member of this programme has only that several structure is very simple to lever, rotating shaft or slide block (chute) except that bed panel, the friction loss of system has also seldom more embodied the labour-saving characteristics.When transferring sitting posture to, middle plate is holded up and is descended to some extent with upper plate, and user's buttocks descends thereupon, is convenient to bunk bed, reduces the possibility of falling down.
