Description

Wheelchair Lift

The utility model relates to truck transport, in particular to passenger inclined lifts, and can be used in hospitals, residential buildings, museums, sports facilities, shops and other facilities for transporting wheelchairs and people with reduced mobility by flight of stairs.

Known elevator for the disabled, containing a cargo platform with a vertical bearing wall and a hinged roof; an adka mounted on rails in the form of rails, two of which are fixedly mounted on the stairway wall and spaced in height, the hinged platform is equipped with a console with a roller resting in working position on the third rail. The elevator is equipped with a manual drive of the loading platform, which includes a gearbox and a drum with a cable. The drive is mounted on a vertical load-bearing wall of the loading platform and is equipped with a removable handle with a protrusion corresponding to the profile of the gearbox output shaft socket (see ed. St. USSR No. 1634618, class B 66 V 9/08, 1991). This lift is inconvenient in operation, since a manual drive is used and all maintenance of the lift is carried out directly by a disabled person.

Closest to the claimed invention by the set of essential features is a lift for the disabled, comprising, containing a cargo platform, made with a vertical load-bearing wall, a folding platform, two upper limit handrails made folding and lower hinged limiting thresholds and installed using the upper and lower suspensions on guides in the form of two tubular rails fixed on the wall and spaced apart in height.

To the application for a utility model

a device for moving the loading platform and a control panel for moving the platform, (see RF patent No. 2116238, publ. 07.27.1997). The disadvantages of the known technical solutions are not sufficiently high manufacturability and manufacture of the elevator, safety and ease of use.

The objective of the utility model is to increase the manufacturability and manufacture of the lift, safety, ease of use, and reduce its cost.

The stated technical problem is solved in that in the well-known elevator for the disabled, containing a cargo platform made with a vertical load-bearing wall, a folding platform, two upper limit handrails made folding, and lower restrictive sills and installed using the upper and lower suspensions on rails in the form two tubular rails mounted on the wall and spaced apart in height, a device for moving a cargo platform and a control panel for moving the platform, cargo platform the frame is equipped with drives for lifting the lower limiting thresholds, each of the drives being made in the form of a linkage mechanism including a first second and third link, a sleeve fixed in the axis of rotation of the platform, which in turn is fixed on a folding platform, additional link passing through the sleeve with the possibility of return - translational and rotational movement and a two-arm lever, one of the shoulders of the latter being pivotally connected through the first link to one of the upper restrictive handrails, the second shoulder is pivotally connected through the second link with one of the ends of the additional link, the other end of the additional link is pivotally connected through the third link to the nut, the platform movement control panel is located on the folding platform of the latter, each upper limit handrail is equipped with an electric limit switch.

electrically connected to the device for moving the cargo platform and placed with the possibility of disconnecting the device for moving the platform with the upper limit handrail raised. The two-arm lever can be made in the form of a rotary axis, and the shoulders are spaced along the rotary axis.

The axis of rotation of the platform can be made in the form of a loop. Additional traction can be performed in the form of a plunger.

In FIG. 1 shows a general view of a lift installed in a building. In FIG. 2 shows a lift with a raised handrail, FIG. 3 shows a lift in an isometric view, and FIG. 4 shows a kinematic diagram of a drive of a lower limiter nut of a lift.

The elevator for the disabled includes a loading platform 1, made with a vertical load-bearing wall 2, a folding platform 3, two upper limiting handrails 4, made folding, and lower folding limiting sills 5 and installed using the upper and lower suspensions on rails in the form of two fixed on the wall and spaced apart by the height of the tubular rails 6 and 7 (Fig. 1), a device for moving the cargo platform 1 and the panel 8 for controlling the movement of the platform (Fig.Z). The cargo platform 1 is equipped with drives for lifting the lower limit sills 5. Each of the drives is made in the form of a lever mechanism, including the first 9, second 10 and third 11 rods, a sleeve 12, mounted in the axis of rotation 13 of the platform 1, which in turn is mounted on the folding platform 3, additional rod 14 passing in the sleeve 12 with the possibility of reciprocating and rotational movement and two shoulders lever 15. One of the shoulders 16 of the two shoulders of the lever is pivotally connected through the first rod 9 with one of the upper restrictive handrails 4, the second its shoulder 17 is pivotally connected through the second link 10 to one of the ends of the additional link 14. The other end of the additional link 14 is pivotally connected through the third link 11 to the nut 5. The panel 8 for controlling the movement of the load platform 1 is located on the folding platform 3 of the latter. Each upper limit 4 is equipped with an electric limit switch electrically connected to the device for moving the cargo platform and placed with the ability to turn off the device for moving the platform with the upper limit handrail raised. The two-arm lever can be made in the form of an axis of rotation 18, and the shoulders 16 and 17 are spaced along the axis of rotation 18 (figure 4). The device for moving the loading platform includes an electric motor drive located on the upper landing.

The lift is maintained by specially trained personnel and works as follows.

For transportation of a disabled person, for example, from the lower landing to the upper cargo platform 1 goes down the rails 6 and 7 and stops. Then the sills 5 are lowered to the lower landing and the disabled person in the carriage drives into the folding platform 3 of the loading platform 1. After the carriage has arrived, the sills are lifted into the transport position by drives, each of which is made in the form of a lever mechanism. When you press the lift button on the control panel, an electric motor is turned on, which rotates the drive sprocket connected to the cable transmission. The force from the upper branch of the cable transmission is transmitted to the loading platform, and it begins to move along rails 6 and 7 along the flights of stairs. During the movement of the loading platform 1, the disabled person holds onto the handrail 4, which increases the safety of the ascent. To improve safety, it is also directed that each upper restrictive handrail 4 is equipped with an end electric switch electrically connected to a device for moving the cargo platform and placed with the possibility of disconnecting the device for moving the platform 1

when the upper handrail is raised, 4. The disabled person is transported from the upper landing to the lower one in the same way. The claimed utility model can be manufactured industrially using modern materials and technologies.
