Description

document GB 2,181,098 discloses a mobility impaired lifting and transport device according to the preamble of claim 1.

The invention relates to a Gehbehinderten - lifting and transport device (hereinafter called GHT ) with a deep horizontal strut, to which at the front end a right and left pivot arm is attached. At their Schwenkarmenden the stub axles for the puncture-proof rubber wheels are placed, which are steered via a steering lever and tie rods. The footrest can be pushed into the end of the horizontal girder and secured with a mounting bolt. The use of the footrest is not mandatory.

At the other end of the Horizontaltragholm is connected by a mounting bolt and connecting plates with a vertical lifting column on which by means of an upstream lifting spindle - driven by a hand crank - a lifting can be adjusted in height.

A seat unit consisting of a seat carrier cross and a padded seat shell is attached to the lift carriage in such a way that the seat unit can be rotated about the horizontal axis. The seat shell itself can also be rotated about the vertical axis. Since the seat unit can be disconnected from the actual GHT and placed in the passenger seat, the entrainment of a handicapped person in a normal passenger car (PW) is made possible without having to make any change to the PW. The load-bearing elements of the GHT can be disassembled in a few simple steps and stored in the trunk or between the car seats.

Using a gallows as an accessory, a disabled person can be picked up by a wheelchair or bed, without much effort by the carer or attendant, and transferred to the GHT .

The proposed GHT is designed in the masses and the structure so that it can be used indoors, on roads and paths.

In contrast to the conventional wheelchairs, support points are provided at the GHT . At these points can be attached two carrying handles and a two-part support bar. This allows easy overcoming of obstacles such as short stairs or level differences. With the use of these aids, which are always supplied with in the footrest, it is possible in many cases to let GHT and its users travel in coaches of the train and not in the mail van.

To operate the GHT's it requires an assistant. The GHT can therefore not replace a normal wheelchair that the patient can move himself. Unless you use the additional wheels - accessories, which can be mounted under the seat unit.

Similar transport equipment, wheelchairs, etc., which are intended not only for indoor use but also for use on roads and paths, have, with exceptions, no Sitzhub-, Sitzneige- and Sitzdreheinrichtung on. If devices with lifting and turning devices are offered, they are either self-propelled or mounted on chassis. Some use the device seat as a car seat at the same time, which requires previous modifications to the vehicle. Furthermore, in many devices, the footrests are connected to the seat and thus complicate the introduction of a patient in today's compactly built vehicles considerably. Another problem is the ever-decreasing ground clearance of the PW's.

The object of the invention is therefore to form a GHT so that it

• Individuals who make a handicapped person more independent at home by being able to carry that person with the GHT in their own normal PW, securely girded, or in many cases by train,
• can be borrowed and used by nursing organizations for private use,
• the often dangerous transport of a handicapped person on the wheelchair in large-capacity vehicles, which are not equipped for wheelchair transport unnecessary,
• enables universal safe use with the simplest operation,
• if not needed, disassemble with little effort and stowed in / on smallest space,
• offers help and work relief to the carers or escorts,
• provides a lift, a seat pivot and a seat tilt device,
• with the help of a suitably equipped "gallows", an assistant allows to pick up a patient from a bed, chair or wheelchair, seated on the GHT seat, drive to the PW with the patient and place in a PW on a seat .
• ensures unrestricted use not only indoors (normal door widths) but also on roads and paths,
• can go under low ground freedoms of PW's,
• the possibility offers when loading a patient into the vehicle carefully "bring in" his head and legs,
• not impeded by seat-mounted footrests, the invitation process,
• can also be finely controlled under the vehicle and thus allows a subtle placement of the patient on the car seat,
• takes into account the different car types and door opening angles,
• during normal travel with the GHT the patient (front of the patient forward) by the angling of the seat provides a comfortable, safe for his senses ride,
• has a safety support that ensures safe transport while driving,
• can be adapted to differing requirements and / or circumstances without much effort
• can be equipped with a comfort seat and or a tilt table,

The object is achieved by the features of claim 1 and explained with reference to the accompanying figures: (All figures without seat - drawn upholstery)

A padded seat shell (1) ( Fig.1 basic unit) is guided on a seat carrier cross (18) by means of seat guides (20) on a support ring and centered in the center by the seat pivot point (32). A padding protection (16) protects the car upholstery from damage. By seat or hand positioning (19) (depending on the version), the seat pan (1) can be rotated or positioned horizontally. The entire seat unit is coupled with the male seat coupling (33) to the lifting carriage (4) in the female seat coupling (34). The coupled seat unit can be rotated with the handwheel (40) and spindle (62 Fig.4) about the axis of the seat support tube (38), or the seat unit can be tilted (Figure 5)

The lifting carriage is adjusted in height on the lifting column (3) by the lifting spindle (14), by means of the lifting spindle hand crank (22) and guided with the lateral lifting slide guides (31). The required power is absorbed by the load rollers (29). The lifting column (3) via the connecting straps (10) on which the castors (9) are fixed, supported on the horizontal spar (11) and connected to it. At the other end of the horizontal beam (11) with the steering wheel (44) steered puncture-proof rubber wheels (12) are arranged. With the brake (9a), the device can be braked or blocked.

In order to drive with the patient to the car or on the road ( fig. 2 device in driving position), the seat unit is bent and secured with a retractable safety support (15). As an additional part, the footrest (13) in the front of the horizontal spar (11) eigeschoben and fixed with a mounting bolt. With the mounting of the support rod (5), the eyebolt (6) and / or the carrying handles (Fig4, 65) there is the possibility to carry the GHT together with the patient over obstacles or stairs. The support rod (5), the eye bolt (6) and the carrying handles (65) can be supplied with and fixed in the footrest (13) when not in use. (See Fig.4)

To invite a patient to a vehicle ( Fig. 6, the seat shell is drawn transparently!), It can be placed in the driving or loading position on the GHT . In the driving position (FIG. 2), one drives to the vehicle and first brings the seat unit into the horizontal position on site. Second, the footrest (13) is placed horizontally if mounted, so that the car body can be driven under the Einschiebevorgang. Next, turn the seat pan (1) with the patient into the insertion position - aligned with the car seat. As a result, the legs of the patient from the footrest (13) must be lifted and let hang freely until then parallel to the open car door, taking into account a Distance for assistance between car door and GHT , moved closer to the vehicle. Now the device - push arm right (2) is pivoted down, the rubber wheels (12) with the steering wheel (44) in the same escape to the edge of the car seat tilted and the legs of the patient (from the intermediate space: car door - GHT from accessible) into the vehicle lifted. After the seat unit has been lowered to the correct height, slightly above the car seat, it is possible to start pushing in the seat unit together with the patient. By tilting the rubber wheels (12), the GHT can be moved laterally (crab) and the whole critical process can be done very subtle and accurate to the millimeter. In the course of the insertion process, the GHT can be moved in any direction and thanks to the seat reclining option, the seat shell (1) of the car seat inclination can be adjusted. After the seat unit has reached the correct position above the car seat, the lifting carriage (4) with the seat unit is lowered onto the car seat with the lifting spindle hand crank (22), the seat unit is decoupled and the patient is belted. The rest of the GHT will now as Figure 8 shows, disassembled, collapsed and stowed the items in the vehicle. When removing the patient, the process takes place in the reverse order.

To relocate severely disabled patients from a wheelchair, bed, etc. on the GHT , a gallows (75) (Figure 7) is placed on the lifting carriage (4), screwed to the prepared attachment point (79) and by straps or towels on the GHT lifted. Lifting carriage (4), lifting spindle (14) and boom - lifting spindle (77) are used as a lifting device. To ensure stability in this type of use, the rubber wheels (12) are to be swiveled forward and fixed in this position. (Accessories Fig.4 Pos.67).

With a tilting table (Fig.9, 80), bedridden persons can be catered for in bed, writing or reading etc. The table size can be chosen individually. If the tilting table (80) is not needed, it can be stowed like a serving tray.

As additional accessories can be mounted additional wheels, with or without motor drive, with which the patient can move himself. (Fig.10, item 81)
