Description

The The invention relates to grinding devices for surface treatment of bodies of foamed plastics or compressed fiber materials for insulation and insulation.

Through the publication DE 299 00 147 U1 is a grinding device, in particular for grinding styrofoam-like materials known. The grinding surface has a substantially smooth-formed region, in which no punched holes or punched edges are formed. This should be a grinding movement in the simplest possible way feasible. Abraded material accumulates in the areas. In addition to the storage effect and a rolling effect should be effected. Nevertheless, abraded material remains between the grinding device and the surface to be machined, so that after a certain removal no or only a limited abrasive effect is present.

Of the The protection claimed in claim 1 is based on the object Material of bodies made of foamed plastics or pressed fibers for insulation and insulation easy to remove flat.

These Task is with the features listed in the protection claim 1 solved.

The Grinding devices for surface treatment of bodies made of foamed plastics or pressed fibers for insulation and insulation characterized in particular that material is easily removable from the bodies.

To are a first plate of a metal with teeth forming Passages and a second plate with openings for abrasion of the body one above the other arranged that the teeth face outward and the second plate on the opposite of the teeth Surface of the first plate is located as well as the breakthroughs the passages and the openings corresponding are arranged to each other. Furthermore, the second plate has a handle or a fastener. By means of the passages are advantageously formed collar, which at the same time the Teeth are for removing material from the body. For this purpose, the first plate consists of a metal sheet, in particular a steel sheet. The passages are simply punched introduced, with the protruding ridge at the same time the collar represents. With appropriate training of the tool are at Punching simultaneously formed the teeth.

The second plate on the first plate serves stability the entire grinding device and at the same time for easy attachment handle or fastener. Furthermore, has the the second plate openings corresponding to the openings the passages, so that over it worn material of the body gets outside. This will be the Abrasion largely not by material between and in the Passages hampered. The grinding device is timed longer compared to a grinding device without openings to use. At the same time can over a Consistent removal rates are achieved over a longer period of time.

advantageous Embodiments of the invention are in the claims 2 to 8 indicated.

To the development of the protection claim 2 consist of the first plate from a sheet metal and the second plate from a plastic. Farther Both the first plate and the second plate have a polygonal one Floor space. In conjunction with a handle is with it an easy-to-use hand tool realized.

To the development of the protection claim 3 consist of the first plate from a sheet metal and the second plate from a plastic. The first plate and the second plate each have a circular Have base, so that the plates are a plate. Furthermore, the second plate has a shaft as a fastening means on. By means of the shaft, the grinding device is advantageously stretched in a corresponding counterpart, the counterpart is coupled to a motor. This is a mechanical removal the body is easily possible.

The second plate is conveniently according to the embodiment of the protection claim 4 connected by means of folding connections with the first plate.

The Collar of the passages of the metal sheet are after the training of the protection claim 5 triangular teeth. In order to a safe removal is ensured.

On the second plate is after the development of the protection claim 6 a hood for receiving worn through the openings abrasion. The hood serves as a collection container for worn Material that can be easily disposed of after processing is.

The Hood consists after the development of the protection claim 7 of a elastic material. Furthermore, the hood for emptying the Abrasion releasably with the shaft and / or at least one connected to the plates. Thus, the hood can be emptied just targeted become.

The Hood exists after the development of the protection claim 8 advantageously made of a plastic or a textile.

One Embodiment of the invention is in the drawings each shown in principle and will be closer in the following described.

It demonstrate:

1 a grinding device for the surface treatment of bodies made of foamed plastics or compressed fiber materials for insulation and insulation with a handle,

2 a grinding device with a fastening means,

3 the first plate with passages and the second plate with openings in a sectional view and

4 a connection of the first plate and the second plate.

A grinding device for the surface treatment of bodies made of foamed plastics or compressed fibers for insulation and insulation consists essentially of a first plate 1 with teeth 6 forming passages 5 , a second plate 2 with openings 7 and a handle 3 or a fastener 4 ,

The 1 shows a grinding device for the surface treatment of bodies made of foamed plastics or compressed fibers for insulation and insulation with a handle 3 in a schematic representation.

The 2 shows a grinding device with a fastening means in a schematic representation.

The first plate 1 from a metal with teeth 6 forming passages 5 and a second plate 2 with openings 7 for abrasion of the body are arranged one above the other. This is shown by the teeth 6 to the outside and the second plate 2 is on the teeth 6 opposite surface of the first plate 1 , Furthermore, the breakthroughs of the passages 5 and the openings 7 arranged corresponding to each other.

The 3 shows the first plate 1 with passages 5 and the second plate 2 with openings 7 in a schematic sectional view.

To do this, there is the first record 1 from a metal sheet, in particular a steel sheet, and the second plate 2 from a plastic.

The second plate 2 is by means of rabbet joints with the first plate 1 connected.

The 4 shows a connection of the first plate 1 and the second plate 2 by means of fold connections.

The collars of the passages 5 of the metal sheet are triangular teeth 6 ,

In a first embodiment, the first plate 1 and the second plate 2 each base in rectangular shape. The second plate 2 has a handle (illustration in the 1 )

In a second embodiment, the first plate 1 and the second plate 2 each a circular base, so that the plates are a plate. The second plate 2 has a shaft 8th as a fastener on representation in the 2 ).

In further embodiments, in addition to the second embodiment is located on the second plate 2 a hood for receiving through the openings of the passages 5 and the openings arranged corresponding thereto 7 got abrasion. The hood is made of an elastic material and is releasably connected to the shaft and / or at least one of the plates for emptying the abrasion. For this purpose, the hood made of a plastic or a textile.
