Cleaning system for those used as public transport Vehicles .

The invention relates to cleaning systems for vehicles used as public transport «,

The invention aims to coordinate the operation of various commercially available machines whose components have previously been changed slightly _v such that due to improvements and developments concerning the construction of which their usability in particular for the interior and exterior cleaning of passenger transportation means such as trains , Subways, buses, motor vehicles, plug-in tools, land and the like, several advantages can be achieved at the same time that have not been achieved in the previous mode of use.

For the cleaning of vehicles of the aforementioned type, especially of trains and underground railways, specialist

A large number of forces are needed to achieve the perfect Take a long time to carry out their cleaning work. The exterior cleaning of vehicles for basic cleaning has so far been carried out in a tunnel-shaped car wash or with hand cleaning with the help of at least two people who carry out their work in the following manner. One spreads over the Vehicle body a suitable cleaning agent, which he applies from a bucket using a brush, while the other washes the outside surface with water and a brush.

So far, the following work has been carried out to clean the inside of these vehicles;

- The interior is swept out using a broom.

- The textile materials are vacuumed using an electrical device.

- The walls, windows, ceiling parts and seats are cleaned by hand wiping with a damp cloth,

- The linoleum floors are wiped over by hand. The seats are also cleaned by hand.

This way of reaching agreement, which has hitherto been the result of its peculiarity vehicles used as public transport have not been further developed or mechanized, brings great difficulties for cleaning companies entrusted with such work, of which the following are the most striking:

1. The high cost of manual work.

909823/0739

2. The poor quality of the work, as the rags or cloths, brushes and cleaning rags remove 50% of the dirt and the remaining 50 % remain distributed on other vehicle surfaces.

3. Due to the high number of employees, the cleaning company responsible Beinigungsarbeiten have intercept ever-increasing · social charges, which has a direct effect on the price, making the execution of Eeinigungs work by mandating expensive is _e

4 «, There is also a risk of complete shutdown in the case of public services as a result of a strike by the cleaning workers *

These difficulties are with the system according to the invention largely overcome or at least severely restricted, since with the help of the invention The cleaning system has the following advantages, among others let achieve?

1. The cost of manual labor can be reduced to 30 % .

2. The prices to be demanded by the client for the leveling work does not increase so much and level off to a normal level.

3. Leave the costs saved in manual labor are distributed among the staff remaining in the employment relationship, so that one has a high wage level receives.

4 "The work can be carried out with a quality of 100 % , because the dirt removed from the vehicle with the help of powerful suction pumps, which are three times more powerful than the electric suction pumps used in industry today, are collected in containers, which are then emptied at specific points.

5 «In the event of work disputes, such as strikes and the like, a single person can clean 25 vehicles that are swept out by vacuuming and where the toilets are cleaned using a water jet blower * Although this is the case Cleaning of the vehicle is not complete, it can at least be used in almost normal condition, so that the vehicles used as public transport do not need to be shut down.

6. The hazards and environmental pollution occurring with the cleaning system according to the invention are almost negligible, since the mechanization of the cleaning method no electrical energy and no machines that cause environmental pollution are used.

The cleaning system provided according to the invention works with compressed air as the driving force for carrying out the cleaning work on passenger trains, buses, airplanes, urban Vehicles, motor vehicles in general, real estate and the like. Depending on the application this compressed air can be supplied from a centrally located station or from moving stations, and these Compressed air is converted using the Venturi effect, which creates a suction effect through which

909823 / 073S

the various cleaning jobs are beneficial have it carried out "

The compressed air generating unit can be operated with gas, electricity, Gas oil, petroleum and the like are fed. This generating unit can be arranged centrally or movably on a cleaning platform. The airflow generated should be between 1600 l / min when using a single unit and 30,000 l / min * when using of three special forces lie.

If a stationary generation station for compressed air is required becomes »what, for example, in certain railway systems or platforms, bus stations and the like The compressed air can be advantageous via a galvanized pipeline system or even via a rubber hose system are distributed, in which case connection points with supply connections are intended * to which the various used in the cleaning system according to the invention Devices can be connected «

One parallel to the aforementioned line arrangement running line arrangement is in most applications an advantage, which is intended to enable a supply of leg restraints and aids, which are explained in more detail below. Centrally located supply connections are also provided here, which ensure that access to the system and the special units is possible in such a way that each Place in the vehicle or in the train wagon can be reached.

If these supply stations are not appropriate or unnecessary, the invention also creates a cleaning system, in which a mobile station for generating compressed air is provided, which is of course self-propelled may or may not be drivable.

909823/0739

At the ends of the ones used to convey the compressed air lines are arranged pneumatic suction pumps or compressed air suction pumps, which are under pressure Air is transformed using the Venturi effect to generate a suction effect, with an appropriate suction strength is between 2100 and 3100 mm water column *

In this context it should be pointed out that by linking the effects of air compression and the Venturi effect, suction strengths can be achieved that were previously not achieved with conventional transportable suction pumps will.

Suction nozzles, which are designed differently depending on the surface to be cleaned, are connected to these compressed air suction pumps via corresponding lines. For example, nozzles with 15 to 25 cm for vacuuming the textile materials of the seats and 25 to 4-5 cm for vacuuming the carpeting of the vehicle are expediently used. For vacuuming hard floors, the nozzles have advantageously Abmessungen.von 25 to 45 cmc for sucking windows, wood paneling _t planar parts and metal parts, artificial leather, leather and the like, the dimensions of the suction nozzles expediently 15 to 25 cm. The angle of all these suction nozzles can be adapted to the work to be carried out, so that an adjustment to the surfaces to be processed is almost perfectly possible and handling by the operator is made easier.

Movable compact display units

When there is a wide range of materials to be cleaned, such as aircraft, buses and Property is available, it is advisable to have a mobile, compact cleaning unit with the following construction

909823/0739

groups to use:

- A Land Rover *, a jeep or similar vehicle, that offers space for three people, and on which the machines necessary to carry out the cleaning work and aggregates indicated below.

- A portable gas oil compressor that is used by the vehicle is pulled and a minimum output of 2.5 nr / min. Has.

~ A machine system with ancillary equipment that does the following comprises: a suction nozzle utilizing the Venturi effect with a suction effect of at least 3100 mm water column; Cleaning machines for the floor, seat surfaces, wall surfaces, ceiling surfaces and exterior wall surfaces; a Set of suction nozzles for dust and liquid; flexible hose lines and rubber hose lines, spray guns for pressurized water, a mixing unit, spray nozzles and a collecting container for coarse waste.

Such a tilting unit is as close as possible the vehicle to be cleaned or the property to be cleaned and the compressor starts immediately set. The additional devices and auxiliary equipment are set up and with the help of rapid insertion connections connected. When the work unit is ready for use, cleaning is carried out in the following way and manner made.

The movable leaning unit can be set up within minutes be put into operation, and immediately after the installation and the execution of the cleaning work can it be moved to other places where

909823/0739

it is needed, as is the case, for example, with aircraft and real estate. On urban buses, for which parking spaces are only available in limited numbers, a movable cleaning unit can be installed in a nearby zone so that several buses can be cleaned without the cleaning unit needs to be moved.
