DE202005017861U1 - Electrically driven rotary brush for cleaning surfaces, includes brush units that are rotated by electric motors connected by cables, and plug-on suction unit - Google Patents

Abstract

The rotary brush includes brush units that are rotated by one or more electric motors connected by cables, and a plug-on suction unit. The rotary brush also includes a circuit breaker and a stepless switch, and can be connected to a sweeping machine to enable the user to use the rotary brush in upright position.

Description

The The invention relates to a hand-operated sweeper with interchangeable To brush, which are electrically driven and rotating over the surface move, weeding of wild growth and weeds as well as for cleaning of fortified and unpaved surfaces and joints.

thought is also the use as Jäthilfe in the garden.

State of technology

Out various known reasons it is necessary, paved and unpaved surfaces, joints and the like to cleanse and weät, since these more or less pollute or, for example, by wild growth, especially ingrown Grass, moss, dandelions or something similar.

This especially for paved or unpaved roadsides, sidewalks or gutters to or with gravel or similar paved areas like e.g. Playgrounds or gravel sports fields.

One another reason for Keeping it clean is the danger of slipping for pedestrians to keep pests away maintain or, for example, have a well-kept environment

The following Publications were researched to the state of the art:

DE 1708658

"Motor vehicle for cleaning roads and parks and the like"
Here, it is proposed that to keep streets and parks clean a motor vehicle with wheels is used which easily recharges leaves and other lying on the ground good or waste, the groupage moves quickly to a Müllabladeort or the like.

DE 2613326 C2

Here becomes an execution described for cleaning sidewalks, streets, squares and the like, the surfaces of chewing gum with the help of hot Pressurized water freed.

GM 7717329

Describes a cleaning machine for cleaning flat surfaces with additional Suction tube with blower to absorb dust, debris, etc.

DE 19627715 A1

Describes an electric joint cleaner in which a rotating standing brush the cleaning takes over. The brush is powered by an electric motor powered by the grid.

DE 29623256 U1

Describes a device for removing fouling from joints of paved Floor surfaces, Here is the rotating brush from the wheels or the wheel axle of the device powered by hand over the floor area depressed becomes.

Other known embodiments, generally described are, for example:
A kind of knife or the like, which is used as a joint scraper and is attached to a short handle. One moves in bent position over the surfaces and has after a short time back pain or similar. This method is very exhausting and usually also not so efficient, because the growth with stronger roots can only be removed badly.

Of the Gas burner is gladly touted as the new racer. Unfortunately packs the burner the evil not at the root, but burns the wild growth, in particular Grass, mosses, dandelions or similar superficial off and the roots remain mostly undamaged and grow after a short time Time again. Furthermore, there is also the danger that by the open flame an uncontrolled fire can be kindled.

Known are also chemical agents used to eradicate wild growth become. Here are additions or the like mixed with water and with a watering can or the like. about the entire surface distributed. With this solution the environment can be polluted and carries a risk, in particular for children, Animals.

Task and solution

Of the present invention is based on the object with low Force and upright and unpaved Surfaces, joints and the like to cleanse and weät, since these more or less pollute or, for example, by wild growth, especially ingrown Grass, moss, dandelions or similar zuwuchern.

Also is the use as a Jäthilfe thought in the garden.

The rotating brushes are driven by one or more electric motors, the choice be powered by a battery with electricity or connected by a cable to the mains.

Of the User can during the activity is predominantly gentle posture occupy, so an upright posture and thus in particular the Move, Protect arms and knees.

Of the User leads the electric powered sweeper practical way with his hands his body. The rotating brushes allow a simple controlled processing of the surfaces to be cleaned and Put.

With the invention mentioned here is a receiving body for the brush with a simple and practical construction, which meets both the commercial requirements and provisions met and to use in the private sector of everyone without effort.

Of the Drive of rotating brushes is done by one or more electric motors, which are infinitely variable are to the speed of the brushes the texture of the surfaces adapt.

Farther are the brushes easily replaceable, so depending on the nature of the processed surface to brush can be used.

The Sweeper can also be equipped with only one rotating brush be advantageous, but at least two arranged brushes, which are also advantageous opposite can be arranged.

In order to an upright posture can be taken during use is extended the sweeper with a handle, the upper end in such a way is designed that one hand or both hands can grip.

Also the on-off switch is close to the hand and / or the infinitely variable Switch for adjusting the speed of the brush or brush.

Farther there is a power plug on the sweeper and / or a receiving body for one commercial rechargeable and acceptable battery, as well as e.g. in drilling machines is used.

Becomes If the sweeper moved to a different location, it could done with the help of one or more support wheels. For that will be tilted the sweeper and loaded the support wheels. The brushes have In this case, no contact with the ground.
