Description

1 103323

The present invention relates to a device for lifting persons with disabilities, comprising a position 5 for attachment to the floor, ceiling or wall, on which a position is mounted, which is at least a substantially sliding sled in which the restraint is mounted for placement. around the extremities of the movement impaired, and lifting means comprising block systems arranged between the belts and the sled, and for lifting and lowering the belts to the desired height, the position comprising a vertical first body part and an at least substantially horizontal second body part which interferes with the vertical the body part which is stored to be pivoted about its longitudinal axis, and the device 15 has displacement means connected to the sledge by which the sledge can be displaced along said second body part along a path.

Known devices for lifting disabled persons are usually called "apertures" and they require that the person should be able to pull himself up in the position with the help of his own hands. A known device of this type comprises a roof-mounted rail along which the sledge can run. In this device, the hoists are an electrical device located between the sledge and the belts. The disadvantage of this known device is that the sledge can run only in the fixed direction defined by the mounting rail. This clearly implies a restriction on the possibility of transporting the disabled person and normally means that auxiliary personnel are needed. In addition, the device is expensive to manufacture. Further, the device can only be attached to the ceiling, which requires a certain pouring strength and some material of the roof. In modern houses, the roofs are not always such that they can function as brackets. One disadvantage, of course, is that the device needs a power supply which can be difficult and expensive to provide. This is especially true since the device should typically be able to be used in wet spaces, such as in bathrooms with bathtubs and toilets.

DE 239 215 discloses a lifting device for transporting a lying patient.

US 4,125,908 discloses a lifting device for persons with reduced mobility in a sitting position. The lifting device comprises a motorized winch that can run along a horizontal latch intended to be attached to the ceiling. The device 10 prevents moving the disabled person into only one piano. Because of this, the device fails to solve the commonly known problem of moving a disabled person between a wheelchair, toilet and bathtub or shower regardless of how the toilet is located in the relationship to the bathtub or shower and without the need for auxiliary staff.

US 3,557,300 discloses a lifting device with a horizontally displaceable sledge and a block system for use in connection with lifting cranes. The sled is displaced by a winch. A crane with a winch for horizontal displacement of a crane wagon is also felt from SE 416 393. Block systems for lifting cranes are felt e.g. from DE 28 45 874.

From US 4,571,758, a motorized device with a horizontal beam and a sledge mounted thereon is felt for moving persons with reduced mobility in a sitting position. 25 Horizontal displacement of the sledge requires that the disabled person raise his hand over his head, grasp the horizontal beam and move along it.

The present device solves said problem and gives the use of a new lifting device which is simple in its construction and use. For this purpose, the device is characterized in that the displacements comprise a first manually operable, mounted in the sled for pulling in by the disabled person and arranged to run via a first deflection member mounted on the stand. Preferably, the first linking member is mounted at a height level which at least substantially corresponds to the height level of the second body member. In this way, the sled becomes easily slidable with little force and the deflection part is not in the way when using the scaffold.

Preferred embodiments of the invention are provided in the appended claims 2-6.

The main advantages of the device according to the invention are that it allows for versatile transport of the disabled person without auxiliary personnel. The device is easy to assemble and simple to its design. No power supply is needed. Advantageously, the device is suitable for retrofitting in existing premises, the hotel being an important area of use. The cost of changing a standard hotel room into a hotel room suitable for wheelchairs is, thanks to the invention, situated. Examples of other areas of use are campsites, hospitals, restaurants, ships and other means of transport.

The invention will be described in the following by two advantageous embodiments with reference to the accompanying drawing in which Figure 1 shows a first embodiment of the device seen from above mounted between a toilet and a bathtub, Figure 2 shows the device according to Figure 1 seen from the side, Fig. 3 shows a second embodiment of the device seen from the side; Fig. 4 shows a third embodiment of the device; Fig. 5 shows a cross-section of the vertical body part of the device. Figures 6 and 7 show an alternative way of attaching the stand to a corner of a room. and Figure 8 shows a way of attaching the device to a wall.

The device of Figures 1 and 2 comprises a position 1 which is fixed by means of a mounting part 2 by means of bolts 3 in the floor. The mounting member 2 has a mounting plate 4 and an upwardly extending cylindrical hollow part 5. A hollow part 5 is arranged in the hollow part 5 with a small clearance lower part of the vertical body part 6. The mounting part 2 is a bearing for the body part 6 which is also cylindrical. . The storage is easy to implement and it is sturdy. Suitable height for the head section 5 is 20 - 70 cm, preferably 30 - 60 cm, since this height provides good support for the other stand. If the device is not used regularly, which may be relevant e.g. in a hotel 15 which has room for both disabled and non-handicapped beds, it is easy to remove it from the mounting part 2. Hereby it is desirable that the hollow part 5 does not have great height, as it could be unnecessary in the road.

The stand comprises a horizontal body part 7 with a web 23 for a sledge 8. The body part has an elongated profile so that it is higher than it is wide, see figure 5 which shows a cross-section of the body part 7. In this way f one is of great rigidity in the body part 7. The body part 7, because of the rotational ability of the body part 6, can be freely displaced in the direction of the arrows, see figure 1. The sled 8, which preferably rolls inside the body part 7 on wheels, can be displaced between the end positions drawn with dashed line through to pull in ropes 9 and 10, see Figure 2. The ropes 9, 10, which are attached to the sledge 8, run over deflection parts in the form of rollers 11, 12. The roll 12 is fixed to the end of the body part 7 and the roll 11 is attached to the other end of the body part 7, since it is possible to utilize the entire length of the body part 7 for the sliding track 23. It is of course possible to alternatively attach the roller 11 to the upper end of the body part 6 or at some place in the area were the body parts 6, 7 joins or likes to practice is available for goods. If the roller is fastened down in position 1, a great deal of force is required to pull in line 9 to move the sledge 8 with the suspended load, which would be an unfavorable solution. When you pull down in Iinan 9, the sledge 8 is moved to the left, and when you pull in Iinan 10 the apron-sledge to the right. It is clear that at both ends of the body part 7 there must be some form of latch which restricts the movement of the slide 8.

Also, to make the ends of the ropes 9, 10 easily accessible, the ropes are arranged to pass through a loop 22 of the sledge 23.

Below the sledge 8 is one with brakes, eg sliding brakes, provided lifting block 13 and more, e.g. six, block wheels. As sledge 8 and lifting block, it is advantageous to use such sledges and lifting blocks as are known in the seal gel industry. The lifting block may consist of two vertically arranged blocks with the required number of block wheels of which the lower block has a latch reading which reads the lower block at the desired height after being released in the line joining the blocks. From the lower part of the lift block 13 hang the device's straps 14, which are intended to be fastened around the extremities of the disabled person. The straps can be made up of a single strap loop with a length of 120 - 200 cm and a width of 50 mm. By pulling the lifting block's ropes 15, the height position of the straps 14 is adjusted above the floor to the desired level to get into the straps. The ropes 15 are readily accessible to the disabled person, as they hang straight below the lift block 13. To make the ropes 9 and 10 extremely easily accessible without having to intervene anywhere, they can be arranged to run through loops 16 of the straps 14. different types can be used: instead of two lines, a system with only one line can be used.

From Figure 2, it can be seen that the body part 6 consists of two telescopically slidable tubes 6a, 6b which 6 103323 have a number of heels 17 which can be aligned in pairs to pass through a pin 18 to read the large part 7 at the desired height level above the floor. The body part 7 can be adjusted to be located between 100 and 200 cm above the floor.

5 Even greater height may be conceivable in some spaces and other applications where there is sufficient space.

Reference numeral 24 denotes a shaft by means of which the disabled can cause oscillation of the horizontal body part 7 relative to the vertical body part 6. The shaft 24 has at its end a hollow 25 which playfully surrounds the body part 6. By lifting the shaft 24 in in a substantially horizontal position, it can freely rotate around the body part 6. If, on the other hand, the end of the shaft 24 is pressed downwards, friction between the hollow 25 and the body part 6. increases by means of this friction, the anti-movement can create a force which causes the road-oriented body part 7 to rotate about it. vertical body part 6.

The device shown in Figures 1 and 2 allows the disabled person to move on his own 20 from his wheelchair 19 into the straps 14 of the device, to lift himself by means of the ropes 15 to the desired height sitting in the straps, to move sideways through pulling the ropes 9, 10 and moving to the desired location, which may be anywhere on the semicircular surface described by the body portion 7 as it is caused to pivot. In this case, the disabled can e.g. get from the toilet 20 to the bath 21 and from the bath directly to the wheelchair 19. The manpower needed to get up and operate in the device is not greater than that required for the movement-hindered head to be able to cope on its own hand in normal toilet and bathroom boards. The danger of slipping is also eliminated, since the person moves in the air without having to take support from the ground. The appropriate length for the body part is 90 - 150 cm. Said length allows a sledge 23 with a length of 80 - 130 cm.

In Fig. 3 another embodiment of the device according to the invention is shown. In Figure 3, analogous reference numerals have been used as in Figures 1 and 2 for corresponding parts. The device of Figure 3 differs from the device of Figure 2 in that the roller 11 and the line 9 are missing. Instead, the body portion 6 at a small angle α in relation to the horizontal plane. Vinkein causes the sledge 8 'automatically on the base of the gravitational force to move towards the body part 6'. This displacement can be prevented by reading with line 10 '. When you want the sledge 8 'towards the free end of the body part 7' you pull in the line 10 '.

Figure 4 shows a simple further embodiment of the device according to the invention. The same reference numerals have been used in the figure as in the embodiments in Figures 2 and 3 for corresponding parts. The embodiment shown in Figure 4 has a bearing 26 '' near the junction between the vertical body part 6 '' and the horizontal body part 7 ''. The bearing 26 '' is a sliding bearing, preferably in plastic, e.g. polyamide. The bearing provides for both radial and axial storage of the horizontal body portion 7 ''. The radial bearing is realized by a flange portion 27 '' in the bearing 26 '' against which the flange portion bears a corresponding flange portion 28 '' of the body portion 7 * 1. The flange portion 28 '' is of metal. The vertical body part 6 '' consists of an adjusting tube which is folded into the floor. The device has no actual height adjustment, but the adjusting tube 6 '' is cut to the appropriate length before installation. Reference numeral 29 '' shows a support in the body part 6 '', which prevents the shaft from falling down.

Figures 6 and 7 show an angularly bent mounting portion 4 '' 'which is secured to a corner of a room by means of tight screws. The mounting member 4 '' 'has a hollow 5' '' which is for receiving the vertical body member 6 '' ''. The lower end of the body part 6 '' rests freely against the floor, see Figure 7 which shows a view seen in arrow A in Figure 6 direction. The vertical body part 6 '' '' and the rest of the device correspond to that shown in Figure 4.

Figure 8 shows a mounting part 4'1 'which allows mounting of the device against a wall. The embodiment shown in Figure 8 can advantageously be used in applications where the floor space is limited. However, the embodiment shown in Figure 8 requires a very solid wall.

The device according to the invention is advantageously manufactured from adjustable tubes, the construction being sturdy and inexpensive. The device is dimensioned to pour a load of 520 kg hanging in the belts 14 at 1500 mm distance from the vertical body part. In this case, the device is calculated to have a safety factor of four for a person of 130 kg.

The invention has been described above by means of two embodiments and it should be noted that the invention can vary in many ways within the scope of the appended claims. In this case, it is conceivable that the stand is fixed to the ceiling instead of to the floor. Floor-mounting is better suited to always being realized. Instead of lines 9, 10, 10 ', chains, wires or the like can be used. The belts 14 may vary in their design. The deflection members need not be rollers 11, 12, 12 'but may be sliding surfaces over which the lines can. run. The length of the vertical and horizontal straight parts can be thought to be so short that the device is suitable for mounting in a small car, the device serving to assist the disabled person in the car and out again.
