Abstract

The utility model relates to a cradle-typed automatically turning over health bed which is composed of a mobile bed body, a power driving system, a position timing controller and a bed frame, wherein, the bed surface is naturally bent and sagged into an arch shape, and the power driving system is composed of a speed reduction motor, a crank and a connecting rod. The utility model has the advantages of simple structure, convenient manufacture and comfortable use. The utility model can be used as a cradle as well as can be used for turning the patients who can not move left and right and laying the patients who can not move with the back or the face toward beds at fixed time.

Description

Cradle-type stands up health care bed automatically

This utility model relates to a kind of health care bed, particularly cradle-type and stands up health care bed automatically.

The health care bed that can stand up automatically all adopts the plane formula bed board at present, and as the patented technology that Chinese patent application number is 90220675.3, it is that the lifting of one-sided bed board is tilted that bed person stands up what lean on.The polylith bed board cooperates lifting to tilt, drive mechanism and control system complex structure, the centrage (being the centre joint of both sides mobile bed plate) that lies in bed is located if bed person is just facing upward, it is stood up is difficult to, moreover because the angle that the both sides mobile bed plate forms when action can make bed person feel not easypro.

The purpose of this utility model be to provide a kind of simple in structure comfortable reliably, can integrate cradle and the health care bed of standing up function automatically.

The purpose of this utility model is achieved in that and adopts the sagging arc bed surface of natural torsion, two long limits of bed surface are separately fixed at forms a pulldown bed body on the bed surface framework of both sides, there is back shaft at the major axis centrage two ends of pulldown bed body, form hinge with the fulcrum roller on the bedstead, and employing crank, endplay device, with the crank is driving link, the pulldown bed body is a rocking bar, with the complete cycle revolving force of decelerator output become the pulldown bed body about swing up and down reciprocatingly, form potential energy, bed person is rolled drivenly stand up, continuously swing, be cradle function, add that positioning timing control just can realize standing up automatically function.

This utility model be adopt one can natural sag bent the arc bed surface, so only need one to overlap actuating unit and timing navigation system, and adopted crank and rocker mechanism, make simple in structure, easy to make, and bed person can be exempted because of mobile bed plate not the relaxing that the angle caused brings of tilting.

Concrete structure of the present utility model is provided by following examples and accompanying drawing.

Fig. 1 is the longitudinal sectional drawing that stands up health care bed according to the cradle-type that the utility model proposes automatically.

Fig. 2 is the automatic turnover bed transverse cross-sectional view of cradle-type that the utility model proposes.

With reference to Fig. 1 Fig. 2, a natural torsion sags into arcual bed surface (2) two long limits and is fixed on the both sides edge of bed (8) of bed surface framework (3), constitutes a pulldown bed body (13), and respectively there is a back shaft (12) at its major axis centrage two ends.The available soft fiber material of arc bed surface (2) is made, and also available hard cuff link material is manufactured, and its developed width (promptly

Length) be advisable with π/3 * bedside (being the air line distance between BC), its simple obtaining value method can calculate by the sagging distance of arc bed surface (2) natural torsion, general span is between the 1/10-1/7 of bedside.

This health care bed also comprises a cover power-driven system (15).Wherein, crank (5) is fixed on the power output shaft of decelerator (6), with as driving link, does the complete cycle rotation, and the other end of crank (5) and connecting rod (4) constitute hinge, and the A point of the other end of connecting rod (4) and pulldown bed (13) bottom constitutes hinge.

This health care bed also comprises bedstead (14).Fixing decelerator (6) on its bottom bar (11), back shaft (12) hinge at the fulcrum roller (1) of the top head of a bed (10) midpoint and pulldown bed body (13) two ends, thereby it is active body that crank (5), connecting rod (4), pulldown bed body (13), bedstead (14) and decelerator (6) are constituted with crank (5), is the crank and rocker mechanism of rocking bar with pulldown bed body (13).Pulldown bed body (13) is an initial point with back shaft (12) under the push-and-pull action of connecting rod (4), about swing up and down, its pendulum angle is best between level ± 25 °, maximum is no more than ± 45 °, it is cradle function that pulldown bed body (13) swing incessantly.

This health care bed also comprises the positioning timing control system (9) that is fixed on the head of a bed (10) and bed surface framework (3) bottom.Its control bit is equipped with that stand up in the left side, stand up on the right side, three kinds of dorsal positions, and the action of every kind of position can arbitrarily be adjusted blanking time as required.When needs stood up automatically, opening control (9), pulldown bed body (13) regularly positioned swing just according to the blanking time of setting, to realize standing up function.Turn off control system (9), pulldown bed body (13) just enters the cradle state.

Claims

1, can be used as cradle, and the cradle-type that bed person is stood up automatically stands up health care bed automatically, wherein, bed surface (2) two long limits are fixed on two edge of beds (8) of bed surface framework (3), constitute pulldown bed body (13); Wherein, an end of crank (5) is fixed on the power output shaft of decelerator (6), and the other end and connecting rod (4) are hinge, constitutes power-driven system (15); Wherein, fixing decelerator (6) on bedstead (14) bottom bar (11), the fulcrum roller (1) of the top head of a bed (10) midpoint is a hinge with the back shaft (12) at pulldown bed body (13) two ends; The A point place of pulldown bed body (13) and the connecting rod (4) in the power-driven system (15) are hinge; Wherein, positioning timing control system (9) is fixed on the bottom of the head of a bed (10) and bed surface framework (3); It is characterized in that: the pulldown bed body (13) of this health care bed is to sag into arcual bed surface (2) by a natural torsion to link to each other with edge of bed framework (3) and form, its major axis centrage two ends respectively have a back shaft (12) and the fulcrum roller (1) of bed (10) top midpoint to form hinge, under the push-and-pull action of connecting rod (4), be lower swing under the initial point with back shaft (12); When opening positioning timing control system (9), whole pulldown bed body (3) regularly positions swing just according to the blanking time of setting, to realize standing up automatically function, when closing positioning timing control system (9), bed surface (2) is swing incessantly just, realizes cradle function.
