Abstract

A therpaeutic bed with the functions of going up and down and chair is operated by hand switch, the back cushion is pushed up by motor driven hydraulic cylinder, the whole bed can also rise by th pushing force of motor driven hydraulic cylinder, the foot part cushion can lower down to right angle position by motor driven hydraulic cylinder to make the bed form a chair.

Description

Have elevating mechanism and have the bed of chair-function

The present invention relates to a kind of nursing bed, for making people with disability's life in bed more comfortable, become the chair shape downwards by the back foot that makes progress, the posture that can be seated is taken food on chair, and owing to have elevating mechanism, can the lower position state easily about.Owing to when nursing lifting unit is risen, the nursing staff can carry out operation at any height and position, thereby has alleviated labor intensity.Slightly risen in the back, foot lifts on slightly than level and can cosily have a rest.

Though existing nursing bed also has the bed of chair-type, do not have elevating mechanism and have the bed of chair-function, do not have that foot is dropped to meet at right angles the position with horizontal level again can be than the bed of lifting two kinds of functions on the horizontal level yet.

The object of the present invention is to provide the life in bed of a kind of people with disability of making and user more comfortable, and can alleviate the nursing bed of medical worker and nursing staff's labor intensity.

The invention provides a kind of bed that has elevating mechanism and have chair-function, it is characterized in that, comprise three driving devices that the electric hydaulic cylinder constitutes that drive lifting unit, back and foot by being respectively applied for, the hand switch of operating, the mat that couples together by back, buttocks and foot, and lifting unit framework; Knee-action is made in the action of the action of this elevating mechanism and the action at back and foot respectively, makes to lift the foot position on the back and drop to from horizontal level then that to descend most point be square position; At foot and the height of regulating bed before the floor contacts by elevating mechanism; When foot dropped to square position, bed promptly became the chair form; This moment, buttocks tilted to the back direction.When using as bed, its foot can be than lifting on the horizontal level.

Adopt above structure, owing to lift very for a short time and can be parked in the optional position with foot lifting noise on the height adjustment, back of bed, user is easy to use, comfortable, and the nursing staff can carry out high efficiency nursing in position, can prevent nursing staff and nurse personnel's lumbago, reduce labor intensity.

The accompanying drawing simple declaration:

Fig. 1 is an axonometric chart of the present invention;

Fig. 2 is the side view of foot of the present invention elevating mechanism;

Fig. 3 is the side view of foot of the present invention elevating mechanism;

Fig. 4 is the side view of foot of the present invention elevating mechanism;

Fig. 5 is the side view of foot of the present invention elevating mechanism;

Fig. 6 is the side view of the elevating mechanism of bed of the present invention;

Fig. 7 is the side view of the elevating mechanism of bed of the present invention;

Fig. 8 is the side view of back of the present invention elevating mechanism;

Fig. 9 is the side view of back of the present invention elevating mechanism.

The bed system that the present invention has elevating mechanism and has a chair-function is by being respectively applied for the driving device that three electric

hydaulic cylinders

3,4,5 of driving lifting unit, back and foot constitute, the hand switch of operating 2, the mat that couples together by back 8, buttocks 28 and

foot

29, and 10,15 formations of lifting unit framework.

As Fig. 8, shown in Figure 9, rise for making back mat 8, make 4 actions of electric hydaulic cylinder and the articulated elements 26 that is installed on the back lifters 7 by bar 25 pullings rises back lifters 7 in the operation by hand switch 2 after the energising.Thereby back mat 8 also rises.Because it is rotating being installed in the pulley 9 of back mat 8, so back mat 8 is bit by bit upwards sliding, buttocks mat 28 is that fulcrum tilts to back 8 directions with 27 then.The position of user can forwards not move.During decline then in contrast.Hand switch 2 one is decontroled and promptly is parked on this position.

As Fig. 2, shown in Figure 3, descend for making foot's mat 29, the operation by hand switch 2 makes 5 actions of electric hydaulic cylinder and is installed in foot's lifters 18 of bar 19 front ends by pulling, and making articulated elements 20 interlock foot mats 29 be fulcrum decline with 27 then.

As shown in Figure 4, because foot's lifters 18 drops to the upright position, so foot's mat 29 also can drop to the upright position.But, the upper frame 10 of bed is risen in order to drop to the upright position.Under the situation that upper frame 10 is risen, pick off carries out sensing at certain position, and foot's mat 29 purgative being prohibited drop to this below position.

Figure 5 shows that the operation by hand switch 2 is risen the foot's mat 29 that drops to the upright position.Foot's mat 29 rises and can rise to higher than horizontal level (Fig. 2).

Hand switch 2 one is decontroled and promptly is parked on this position.During decline then in contrast.

As Fig. 6, shown in Figure 7, to rise for making upper frame 10, the operation by hand switch 2 makes 3 actions of electric hydaulic cylinder, bar 21 roof pressure articulated elements 22, thus arm 17 is risen; In addition by articulated elements 24 and arm 16 being risen with transmission bar 23 interlocks and roof pressure that articulated elements 22 laterally is connected, and since arm 13,14 rise because of the rising of

arm

16,17 also interlock, so upper frame 10 risings.

During decline then in contrast.Hand switch 2 one is decontroled and promptly is parked on this position.

Because nursing bed of the present invention both can be the chair state, can adjust the whole height of bed again arbitrarily, so be applicable to old man's nursing unit and general family.

Claims

1. bed that has elevating mechanism and have chair-function, it constitutes, and knee-action is made in the action of the action of elevating mechanism and the action at back and foot respectively, makes to lift the foot position on the back and drop to from horizontal level then that to descend most point be square position; At foot and the height of regulating bed before the floor contacts by elevating mechanism; Bed becomes the chair form when foot drops to square position; This moment, buttocks tilted to the back direction; When using as bed than lifting on the horizontal level.
