Abstract

The broom has a sloping scraper (4) fastened to the top of the broom head (2). The head can be turned over to allow it to be used to remove e.g. ice or cement deposits from the ground.

Description

The The invention relates to a broom in which at one end of a handle a brush holder attached is that a brush wearing.

Such Brooms are to be cleaned to remove dirt particles surfaces used.

To the To solve Contaminations that are firmly connected to the surface to be cleaned (ice during Snow shoving, separation of permanently dried cement or gypsum pieces Formwork in construction) one additionally Scraper.

from that There is the disadvantage that for the person responsible for cleaning the area to be cleaned either one Broom or scraper must have in hand. Both tools are not in a device united. this leads to to that when cleaning big surfaces (e.g., construction sites, streets, etc.) a high running and thus time / cost is the, Tools at the right time at the required location To have a hand. Since a scraper is only partially needed, it usually stays at the last used point of the surface to be cleaned and then later be retrieved from this point again.

The to be solved by the invention The task is to overcome these disadvantages.

This takes place in that on the brush holder a Scraper is mounted in such a way that it can be turned by turning the handle can be brought into working position.

you So with just a "broom" as a broom, as well as - after easy turn of the handle by 180 ° - use as a scraper.

The The invention further relates to various advantageous developments.

embodiments The invention will be described below with reference to the accompanying drawings. They show:

1 a schematic representation of a first embodiment;

2 and 3 the representation of the use of the embodiment according to 1 in the first working position (sweeping position) and the second working position (scraping position);

4 a schematic representation of a second embodiment in sweeping position;

5 a schematic representation of the embodiment according to 4 in a scraping position;

6 a third embodiment;

6a the scraper of the embodiment according to 6 ;

7 a fourth embodiment;

7a the scraper of the embodiment according to 7 ,

The embodiment according to 1 has a handle 1 on, at the lower end of a brush holder 2 is arranged, in which bristles - usually bundles - are introduced, which is a brush 3 form. At the same (lower) end of the handle 1 there is also a scraper 4 which is formed by a folded sheet metal. The first part surface 4 ' is on the brush holder 2 on the upper side surface 2 ' is arranged, that of the surface, at which the brush 3 is disposed opposite. The subarea 4 '' stands from the partial surface 4 ' with an angle of 90-130 °, so from the side surface 2 '' with an angle of 0-40 °, starting from that between the side surface 2 '' of the brush holder and the partial surface 4 '' a wedge-shaped diverging spread is given. The subarea 4 ' the scraper is with the upper side surface 2 ' of the brush holder 2 screwed. It is under modification of 1 also possible, the scraper with a partial surface on the side surface 2 '' then attach and then edge so that a further partial surface opposite to an extension of the side surface 2 '' forms an angle of 0-40 °.

2 and 3 now show this scraper in perspective in Kehrhaltung ( 2 ) and in Schabehaltung ( 3 ). The direction in which swept (KR), and the direction in which scraped, are denoted by KR and SR. The scraping arises from the sweeping, thereby giving the handle 1 rotated by 180 °, relative to its longitudinal axis.

This type of handling is extremely convenient, for example, when cleaning road surfaces at construction sites, in field trips, cleaning scaffolding boards from cleaning debris, scraping chewing gum on flooring, scraping weeds growing through the flooring, when performing snow and ice clearing. In all these cases you have to scrape off stuck dirt on the lower surface. This is done with the scraper. If they are then scraped off, ie detached from the surface to be cleaned, they can be swept up with the broom. There is hardly any additional weight on a conventional broom. Furthermore, without limitation, the sweeping function is a easy handling guaranteed. Since you have realized both the scraper and the broom in a tool or cleaning device, running paths are unnecessary to get the other device if you need it. This leads to shorter cleaning times and accordingly to a cost saving for cleaning personnel and thus to an increase in efficiency during cleaning, since the scraper is always available immediately.

Already the embodiment according to 1 in which the scraper on the brush holder 2 can be attached by two or three screws, makes it clear that the scraper can also be interchangeable as a replaceable module ("change module").

How out 2 can be seen, is the width of the scraper 4 equal to the width of the brush holder. This also allows you to sweep and / or scrape directly on a curb.

The angle of the subarea 4 '' the scraper on which the scraping edge 5 is provided, from the ground should be in sweeping from the ground about 40-60% of the bristle length to ensure that the scraper does not interfere with sweeping (see. 2 ).

The angle of the scraping plate relative to the bottom when brooming in scrape position is ( 3 ) is about 30-40 °. If particularly bulky obstacles are to be scraped off, such as adherent ice or permanently dried plaster in formwork, it may be appropriate to move the scraper almost parallel to the area to be cleaned. This corresponds to an angle of only slightly more than 0 °. In working position, the angle W (see 3 ) relative to the surface to be cleaned 0-40 °.

The scraper can be made of metal (preferably for outdoor applications), but also of plastic in household applications. It should preferably be ensured that rounding of all corners to prevent unforeseen damage during handling are provided. The thickness of the sheet in the area of the scraping edge 5 the scraper 4 should be 1.0-2.0 mm.

The scraper 4 Can either as a separate part between handle 1 and brush holder 2 be attached, or combined as a part with the handle.

Another embodiment is in 4 and 5 shown. This is the scraper 4 folded twice and that at the edges 21 . 22 , ie there are three partial surfaces 4 ' . 4 '' . 4 ''' so that the subarea 4 ''' holding the scraping edge 5 has, practically parallel to the brush 3 runs. So you can with a very acute angle of almost 0 ° or just over 0 ° scrape a stuck dirt or piece of ice from a surface to be cleaned, without that you would have to stoop strong.

The 6 and 7 show the training of the invention in conjunction with Handfegern, where the handle 11 in the brush holder 12 linear, that is, the extension of the former forms.

The scraper 14 has over most of its length in both cases a U-profile, which is produced by bending the sheet or - when manufactured from plastic - by a corresponding injection process. The two legs of the U-shape are designed so that they fit on the side surfaces of the brush holder. The attachment can thus be supported by a clamping action.

Due to the linear connection of brush holder and scraper is achieved that the scraping edge 5 always parallel to the plane of the handle.

In a design of the scraper as U-profile up to the front end of the scraping edge 5 ( 6 ), the scraper can be used simultaneously as a scoop for smaller parts ( 6a ), this in the embodiment according to 7 . 7a not the case.

When designing the brush holder 2 made of plastic can advantageously provide that the scraper is integral with the brush holder.
