Definitions
- the invention relates to construction technology and concerns a minihoist.
- US 2 535 221 discloses a lift comprising a hydraulic cylinder attached to a special kind of an articulated jack.
- the jack is used for moving a platform between a lower and an upper level.
- the structure is quite complicated and requires a relatively big room below the floor plane.
- US 5 461 736 discloses a portable step stool for handicapped patients.
- the stool comprises an upper base which can be raised by means of a manually operated hydraulic jack.
- the stool is provided with wheels for moving the stool on the floor.
- the invention comprises a hoisting device which is flush with the floor, and a lift plane which is moved by the hoisting device.
- the lift plane can be lowered as low as possible in its lower position, so the ramp to the plane can be as short possible, or sometimes no ramp is even needed.
- the distance of the lift plane from the floor in its lower position is preferably about 2 cm at the most.
- the hoist can be hydraulically or electrically driven, for example.
- One advantage of a hydraulic hoist is that the portion which is flush with the floor is generally relatively small.
- the hydraulic hoist can also easily be made suitable for outdoor use.
- Another object of the invention is a handle attached to a wall which can be used as a support by a person who is moved by the hoist.
- the minihoist comprises lift member 1 placed in front of a threshold on a floor.
- Lift member 1 comprises vertical hydraulic cylinder 1a and piston 1b.
- Piston 1b comprises upper arm 1c.
- Cylinder 1a is submerged in the floor so that only its upper end is above the floor level.
- the upper end of cylinder 1a is provided with a flange-like fastening part 2 by which the cylinder is attached to the floor.
- channels required by hydraulic and control cables are made in the floor.
- the hydraulic machinery is placed in a suitable location, apart from the hoist. The same machinery can be used to drive several hoists. Control of the hoist can be implemented, for example, pneumatically or by low-voltage electricity. If the hoist is used outdoors, for example, on a balcony; naturally, a proper cold resistant hydraulic oil is used.
- Hydraulic cylinder 1a according to Fig. 3 comprises one piston 1b.
- Cylinder 1a according to Fig. 4 comprises two nested telescopic pistons 1b, of which the innermost one can be lifted above the outer piston.
- the solution according to Fig. 4 provides higher lift height by cylinder 1a of the same length.
- Supporting part 3 is attached to the upper end of the innermost piston rod 1c.
- the upper surface of supporting part 3 is provided with lift plane 4.
- the front edge of supporting part 3 comprises ramp 5 which is attached to the supporting part to be pivoted on hinge 6 in the vertical direction.
- the sides of supporting part 3 comprise side shields 7 attached to the floor.
- Supporting handle 8 is attached to a wall at a suitable height on the side of the opening edge of door 9.
- Handle 8 protrudes vertically from the wall.
- Handle 8 comprises a ring attached to the wall and a rod extending straight down from its lowermost point, the lower end of the rod being bent against the wall.
- a person can grip the handle firmly with either hand, When desired, one can also push his or her arm through the ring.
- the hoist is particularly intended to be used so that the person places him or herself on it sideways. In this case, it is as easy as possible to get support from the handle and move through the door.
- Lift plane 4 comprises operating switches 10 of the hoist which are operated by foot. When one of the switches is pressed, the lift plane ascends and when the other one is pressed, it descends. The switches are placed side by side on the edge on the side of supporting handle 8 of lift plane 4. In this way, the user naturally finds the best possible position on the lift plane.
- Supporting member 3 is as low as possible. Therefore, the distance of lift plane 4 from the floor is preferably about 2 cm at the most in its lower position. In this case, the length of ramp 5 is about 16 cm, for example.
- a suitable length for hoisting a standing person and a suitable length of lift plane 4 (perpendicular to the wall) is, for example, about 30 to 35 cm.
- the length of a plane suitable for hoisting a wheelchair for example, is 70 to 100 cm. It is easy to move onto low lift plane 4 which is in its lower position, and away from it. Low-gradient ramp 5 makes moving even easier.
- Operating switches 10 can be used to cause lift member 1 to move the lift plane to the desired direction in the vertical direction.
- the sufficient maximum lift height in normal apartments is generally about 20 cm which can be accomplished by the above-described telescopic, hydraulic cylinder which is flush with the floor.
- a lift height of about 10 to 15 cm is easily achieved by a simple cylinder.
- the operating switches can be placed at a suitable height on the wall when desired.
- side shields 7 are rounded so that they do not hurt the user if he or she falls.
- the location of hinges between lift plane 4 and ramp 5 and the gaps between side shields 7 and the lift plane and the ramp are constructed so that fingers or toes cannot get caught between them and that they will not pinch the skin.
- a suitable distance of side shields 7 from lift plane 4 and ramp 5 is about 5 mm.
- the gap between lift plane 4 and ramp 5 is covered by the back part of the hinge.
- the minihoist makes it possible for disabled persons to safely move from one plane to another. During the transfer, the person can hold handle 8.
- the hoist is small in size and it can be accommodated easily in the rooms of normal apartments. Because of its small size, the hoist hardly disturbs other activities.
- the vehicle When moving by a vehicle, such as a rollator or a wheelchair, the vehicle can be left on lift plane 4 and the user can move forward with the aid of rails 10 and other supports that are properly installed. In this way, it is not necessary to the take the vehicle to a wash-room where there often is very little room to move. In this case, the wash-room must be provided with suitable supports which make it possible for the person to move.

In this way, it is not necessary to the take the vehicle to a wash-room where there often is very little room to move. In this case, the wash-room must be provided with suitable supports which make it possible for the person to move.
- minihoist One special use of the minihoist is the fronts of the doors of wash-rooms built of prefabricated structures. Typically in apartments there is a step of about 80 to 140 mm at the door of such a wash-room. Other objects include balconies, porches, and the fairly small differences in levels typical for detached houses built on a slope.
- Lift plane 4 and ramp 5 can be coated with suitable material which prevents slipping.
- the materials and colours of the hoist and the handle can be selected according to the interior decoration.
- the structure of the hoist is fairly simple and it is easy to put in place.
