Description

The inventive utility model is intended to facilitate the movement of disabled wheelchairs and citizens with prams along the flights of stairs.

There are ramps that are installed in places of existing development, where it is impossible to install stationary ramps and elevators with a horizontal platform due to the small width of the flights of stairs and the large angles of inclination of the stairs.

There is a known ramp for moving wheelchairs and prams along staircases, containing two guides rigidly connected to each other in the transverse direction with the possibility of changing the distance between them (patent for utility model of the Russian Federation No. 42421 IPC A61G 5/06). Moreover, one of the guides is pivotally attached to the racks of the stationary railing with the possibility of rotation and fixation relative to them inoperative.

The disadvantage of this ramp is the impossibility of its independent use by wheelchair users due to the need to exert great physical effort while folding the ramp.

A well-known ramp designed for the unimpeded movement of people with limited mobility (patent pa utility model of the Russian Federation No. 76044 IPC E04F 11/00, A61G 5/06). This technical solution contains two guides interconnected by brackets with the ability to change the distance between them, railings, racks, consoles, rigidly attached to one of their guides.

The disadvantages of this design are:

- failure to comply with safety requirements, as the user during operation of the ramp can stumble on the bracket;

- large overall dimensions when folded, i.e. a folded ramp blocks part of the flight of stairs;

- insufficiently high operational reliability associated with the use of a torsion beam;

Known ramp designed to move goods and wheeled vehicles on different levels of the plane, including stairs (patent for utility model of the Russian Federation No. 68298, IPC A61G 5/06). This ramp contains two runners of profiled material, parallel connected between each other by transverse ties, a hinge assembly of one of the runners to the supporting surface.

The disadvantage of this design is the failure to comply with safety requirements, because the user during operation of the ramp can stumble on the bracket.

There is a ramp for the movement of groups of people with disabilities and citizens with prams in places where there are restrictions on the installation of a stationary ramp (patent for invention of the Russian Federation No. 2379440, IPC E04F 11/00, 2008). This ramp contains two guides interconnected with the possibility of changing the distance between them, two racks, bearing railing, beam and cross members. In the idle state, the guides are shifted to the beam.

The disadvantages of this ramp are:

- insufficiently high operational reliability associated with the use of a torsion beam;

- the impossibility of its independent use by wheelchair users;

- the ability to install only in places not equipped with fixed rails;

- failure to comply with safety requirements, as the user during operation of the ramp can stumble on the cross member.

This known device is taken as a prototype.

The technical result that can be obtained by implementing the claimed utility model is: reducing the required physical effort during folding / unfolding the ramp makes it accessible for use by mothers with prams and wheelchair users, increasing the operational reliability of the ramp, and the possibility of installing the ramp on flights of stairs, both equipped and not equipped with fixed handrails, the possibility of adjusting the gauge of the ramp in the unfolded m condition, adjusting it to the current size of the baby or wheelchair.

The specified technical result is achieved due to the fact that the sliding ramp contains two sliding rails, at least two transverse rails, characterized in that the transverse rails are located on the steps of the stairs, and the sliding rails are connected to the respective carriages of the transverse rails by means of supports.

In addition, the supports contain elastic elements.

In addition, the carriage is configured to connect to the drive element.

In figure 1. depicts a variant of the ramp sliding in the unfolded state.

Item Name:

1 - sliding guide

2 - sliding guide

3 - transverse guide

4 - carriage

5 - support

6 - carriage

7 - railing

Figure 1 shows a sliding ramp containing two sliding rails 1 and 2, parallel to each other, two transverse rails 3 located on the steps of the stairs. In each transverse guide 3 there is a carriage 4, which is connected to the sliding guide 1 by means of supports 5. Also, in each transverse guide 3 there is a carriage 6 of the sliding guide 2. When the ramp is folded, the sliding guides 1 and 2 are, for example, on the side of stairs under the railing 6. The transverse guides 3 can be attached to the stairs, wall or railings, the choice of mounting method is determined based on the convenience of installation on a particular staircase. The railing can have a structure that completely or partially hides the sliding rails 1 and 2 underneath when folded.

The device operates as follows.

When folded, the sliding guides 1 and 2 of the ramp are located next to each other on the side of the stairs under the railing. The carriages 4 and 5 are in their extreme position near the transverse guide 3, which is closest to the railing of the end face.

To bring the ramp into working position, the sliding guides 1 and 2 are moved along the transverse guides 3 due to the movement of the carriages 4 and 5. The position of the sliding guide 2 is adjusted depending on the gauge of the wheelchair or baby carriage being moved along them.

After using the device, the sliding guides 1 and 2 are shifted to the wall, freeing the flight of stairs.

When the carriage is configured to be connected to the drive element, the drive element automatically extends the carriage together with the sliding guides to the working position and shifts them back to the wall, freeing up the flight of stairs after using the ramp.

When using elastic elements in the construction of supports in an unloaded condition, the sliding guides 1 and 2 are slightly raised relative to the steps. Moving along the transverse guides, they do not touch the elements of the flight of stairs. Under the weight of the stroller, the elastic elements of the supports bend, thereby lowering the sliding guides onto the steps.
