NO137810B - LIFTING AND TRANSPORTATION APPLIANCE FOR MOVABLE DISABILITIES - Google Patents

Description

The present invention relates to a lifting and transport device for the mobility-impaired which comprises a driving

bare stand, one placed on the stand first pillar and one on

this height-adjustable second pillar supporting a saddle-shaped seat.

In the case of lifting and transport devices of the kind mentioned at the outset, efforts have been made to place the seat

in rather large avs/teeth from the other column with the help of one or more arms. As a result of this large distance between the seat and the column, it is necessary to dimension the arm or arms so that these can transmit large forces. A large distance between seat and column also means that the stand's wheels must have a large distance between them so that the lifting and transport device does not tip over when driving. The mentioned arms also limit the possibilities of using the lifting and transport device in a way other than as a wheelchair for the disabled.

The purpose of the present invention is to eliminate these disadvantages and to provide a lifting and transport device of the type mentioned at the outset, which

pretends that you partly get rid of rough arms for the seat's placement, partly you can dimension the undercarriage significantly smaller than before without therefore risking that the apparatus will have poorer stability, partly you can convert the apparatus from a wheelchair to a walker in a simple and efficient way. This is achieved according to the invention in that the second column has a holder which is arranged partly to hold the seat in a normal position where the front edge of the seat has a small distance from the column, and partly to hold the seat in a folded position, as a wider part of it the saddle-shaped seat is located farthest from the column when the seat

is set in the normal position and furthest up when the seat is up-

field, in which position a substantially flat upper side of the seat is closest to the pillar.

The invention will be explained below

in more detail with reference to the drawing, there

fig. 1 illustrates a first embodiment of

the device according to the invention, seen from the side,

fig. 2 illustrates the same apparatus, seen from above,

fig. 3 shows a second embodiment seen from the side

since, and

fig. 4 shows the embodiment according to fig. 3 sets

from above.

The lifting and transport device according to fig. 1

and 2 includes a relatively low undercarriage 1, e.g.

in the form of a framework of pipes. In the embodiment shown

shape, the undercarriage 1 is largely rectangular and open on one short side and at the corners equipped with pivotably mounted wheels 2. On the opposite short side of the undercarriage, in-

fixed a vertical first column 3, in relation to which is displaceably arranged a 'second column 4, on which a seating surface 5 is fixed via an arm 6, which can be limited pivotably stored on the column 4, e.g. by means of a hinge not shown here or a hook device 7, whereby the seat can easily be swung up or squatted off. Two armrests 8 are arranged above the second pillar 4 and the pillar 4 can be adjusted in height in a manner known per se by means of a steering wheel 9

via a movement screw/nut device arranged inside the column, not shown here. The steering wheel 9 can be equipped with a swing-up handle 10 for quick adjustments.

frame 1 there is a foot support in the form of a plate 11.

When the above-described device according to' fig.

1 and 2 are to be used to move a seated, mobility-impaired patient, the seating surface 5 is first set to a suitable height after which the seating surface is pushed under the patient's seat, between the patient's legs. With the help of the steering wheel 9, the column 4 and thus the sitting surface 5 can then be raised, so that the patient's weight is transferred to the sitting surface and the patient can be moved from the piece of furniture unimpeded, e.g. a bed, from which the transport will take place. As the underframe 1 is made very low, it can be pushed in unhindered under even relatively low seating furniture and, of course, without hindrance pushed in under e.g. a bed. By choosing a storage point for the column 3, mostly at the center of one short side of the undercarriage, a favorable, safe weight distribution is achieved. Between the 8 free ends of the arms, a removable backrest, not shown here, from one or both ends, e.g. in the form of a belt (salgjord) etc. be arranged. Furthermore, the lifting and transport device according to fig. 1 and 2 be provided with suitable handles, not shown here, for driving the chair. Using the one in fig. 3 and 4, the device shown makes it possible - to drive forward as close to a toilet seat, bathtub, tub etc. that a patient who is on the seat of the lifting and transport device can easily be lowered down or otherwise transferred to the toilet seat or another seating device by a shower cabinet, a bathtub, tub etc. It is further achieved that the patient can be transferred from the side onto the seat and that reversal can easily take place with the help of easily accessible handles.

For these purposes, the lifting and transport device according to fig. 3 and 4 provided with a rollable undercarriage, which, in contrast to the one just described, consists of a front part 12, which carries the first column 3 as well as two of the wheels 2. The other two wheels or rollers 2 are arranged at the free end of each its arm 13a, 13b, which is pivotally connected to the front undercarriage part 12 via vertical shafts 14. With the help of locking devices not shown, the arms 13a, 13b are normally held in the position shown with solid lines, in which the arms are mutually parallel, but by releasing the arrester the arms can be swung out to that in fig. with dashed lines shown position. Through this, e.g. the advantage that the lifting and transport device can be easily maneuvered up to a toilet seat etc., which is wider than the normal distance between the two wheel arms 13a, 13b. In the embodiment shown, the columns 3 and 4 constitute the piston or cylinder in a pressure medium-actuated lifting device. A pump arm 15 is used to move the columns, which is conveniently accessible to the patient.

To make it easier for the patient to get on and off from the side, the armrests are individually Torskivbare. For this purpose, at the upper end of the column 4, there are arranged two spaced apart sleeves 16 for the same displaceable and lockable tubes 17a, 17b, which make up the armrests. The two tubes 17a, 17b have handles 18a, 18b at their two ends for the movement of the lifting and transport device in different directions. On the pipes 17a, 17b, fasteners 19 can also be placed if necessary

■support straps 20 et seq., which prevent patients who have difficulty controlling their movements from falling forwards or backwards. These mounts are also adjustable to achieve the most appropriate position for the same. Between the sleeves 16 or the tubes 17, a table 21- can be placed in front of the patient, the table preferably being displaceable, pivotable or removably fixed between the two tubes 17- At one end of the chassis, a foot plate 22 is attached either in a similar way as for the table 21 or the can be permanently connected to the undercarriage.
