Password; Cleaning and polishing mats with holding device for polishing machines

Description;

It is known among the bur & tent plates of floor polishing machines for the processing of floors and similar surfaces to lay round, disc-shaped or ring-shaped mats made of suitable material such as cotton or wool felt, synthetic felt, with or without impregnation, Steel wool in braided or needled form, textile fabric, lamb's file, etc. are made to produce the desired Achieve cleaning and polishing effects. These mats are usually mentioned by the bristles of the brush plate Polishing machines detected and thereby set in rotating motion ', whereby the desired cleaning or Polishing effect is achieved.

The disadvantage of this previously known and mentioned type of mat and working method that

1.) when lifting the floor polisher off the floor, for example When transported over door sills and stairs, the mentioned mats can easily come off the bristles and must be carefully centered again under the brush plate; ·

2.) Tass these mats even when working yourself, especially at Unevenness in the floor or when bumping into obstacles, shifting eccentrically under the brush plates, as a result the running of the machine becomes restless and the mats

:. ' shredded or thrown out.

The present invention overcomes these drawbacks as follows:

The brush plates mentioned are usually x) in accordance with the figure I with letter a) or bolt-like spring clips b) attached to the work plate c) of the polishing machine, with usually two such fasteners are sufficient; in the case of large workers over approx. 20 cm 0 are also occasionally still several such fasteners in use. These fasteners are often bored hollow or can be made with a centric bore without great effort.

Said disc-shaped round mats d) receive one or more slots e), the length of which the distance and the Position of the above fastening elements a) or b) correspond. Furthermore, on the side facing away from the floor a round disc f) at least 3 mm thick made of suitable elastic, inexpensive material such as foam, steel wool felt, Wood wool felt, paper felt, etc. - attached concentrically,

At the ends of the slots e) this disc f), the outer diameter of which corresponds to the inner diameter of the bristle ring g) of the brush plate x), has a small hole h). A bracket i) made of steel or metal wire or similar suitable elastic material serves as the fastening element, the two legs k) of which are bent in such a way that they reach through the round mat d) with disk f) into the holes of the fastening elements, similar to electrical plugs a) or b) match. The ends of the two legs k) are resilient, be it by slitting, bending or similar measures known per se, so that the bracket i) is held in a friction-locked manner in the bores mentioned in the fastening elements a) or b). The length of the two legs k) is matched so that the center piece of the bracket i) comes to lie in the slot e) of the mat d) in the assembled state, i.e. does not touch the floor when working. The finished, disc-shaped round mats d) + f) are secured in this way by the bracket i) against unintentional loosening or falling, are centered by the disc f) on the inner edge of the bristle ring e) and can still be easily and effortlessly pulled out as desired of the bracket i) can be removed or changed. Protection claims; These extend on disc-shaped round cleaning and polishing mats with holding devices, intended for use under the rotating brush plates of floor polishing machines, characterized in that 1.) The cleaning and polishing mats consist of two concentric superimposed interconnected rounds Disks are made, the lower, larger one being designed as a working disk and having at least one slot, the length of which corresponds to the distance between the holding elements on the work plate of the polishing machine; 2.) the above-mentioned smaller disc serves as a centering disc and is at least 3 mm thick, has an outside diameter that is equal to the inside diameter of the bristle ring of the. Brush plate, also has at least two holes, each at the end of the in claim 1) said slot are arrangedj 3.) the holding device made of at least one made of elastically resilient material such as steel or metal wire or the like Material: manufactured bracket is made, the two legs of which are bent approximately at right angles and such a distance have from each other that this corresponds to the distance between the holding elements on the work plate of the floor polishing machine, finer at the ends of these two legs there are elastically resilient members which .in the cavity of the - 3 - Sheet - 3 - . 38mo * -U vs. Engage retaining elements of the brush plate and in it are frictionally recorded; 4.) the length of the legs mentioned in claim 3) Holding device is dimensioned so that its back in the assembled state in the in claim 1) mentioned The slot of the working disk is embedded and does not touch the surface to be machined; 5.) the larger, lower working disk mentioned in claim 1) made of cotton felt, wool felt, plastic felt, textile G-ewebe, - lambskin or similar suitable Material with or without impregnation, as well as steel wool in braided or needled or otherwise matted shape can be formed; 6.) the above-mentioned centering disc mentioned in claim 1) and 2) may or may also consist of the same material as the working disk mentioned in claims 1) and 5) made of other suitable material such as foam, wood felt, Steel wool felt, paper felt, etc. Haslaeh i.K., July 2nd, 1968 ERNSTHAISS 'iron- υ.
