    background
    The present invention relates to a device for protecting edges. In particular, the invention relates to a device for protecting vertical edges of concrete walls or horizontal parapets.
    State of the art
    The protection of wall edges can already be important in wall construction, as shown for example in EP 1 221 513 A1. This document shows an edge protection profile that serves as a plaster profile. The edge protection profile consists of a metal sheet, which is folded along its longitudinal center axis, so that the two side parts which adjoin the tip formed by the folding first run parallel to one another and then are folded again, so that the ends of the side parts opposite the tip form an angle of enclose approximately 90 ° to each other. The ends of the side parts are attached to an unplastered wall edge. If a plaster is applied to the wall, the plaster is applied up to the height of the top. The edge protection profile remains in the plaster and continues to serve as edge protection, so that on the one hand the plaster has sufficient hold in the edge area and on the other hand it can be avoided that plaster crumbles off the edge if an impact is applied to the edge or if the edge is accidentally touched by an object .
    It is also known from US 20120047811 A1 to attach mudguards to garage doors, in particular to avoid that a seal attached to the edge of the garage door is damaged by contaminants or by biting by rodents. The edge protection profile is attached to the side walls of the garage door using adhesive strips.
    These two edge protection profiles have in common that they are permanently attached to the edge to be protected in order to protect the edge for its entire service life from bumps, weather conditions or from biting.
    There is therefore a need for an edge protection profile which can be temporarily attached to a vertically running edge, for example to temporarily protect the edge from damage during construction or renovation work. If an edge, especially a concrete edge, is damaged, repairing the damage can be costly.
    Object of the invention
    It is an object of the invention to develop a device by means of which an edge can be temporarily protected from damage.

    The object of the invention is achieved by a device according to claim 1. Advantageous exemplary embodiments of the device are the subject of claims 2 to 10.
    When the term "for example" is used in the following description, this term refers to exemplary embodiments and / or embodiments, which is not necessarily to be understood as a more preferred application of the teaching of the invention. Similarly, the terms “preferred”, “preferred” are to be understood by referring to an example from a set of exemplary embodiments and / or embodiments, which is not necessarily to be understood as a preferred application of the teaching of the invention. Accordingly, the terms “for example”, “preferably” or “preferred” can refer to a plurality of exemplary embodiments and / or exemplary embodiments.
    The following detailed description contains various embodiments for the device according to the invention. The description of a particular device is only to be regarded as an example. In the description and the claims, the terms “contain”, “comprise”, “exhibit” are interpreted as “contain, but not limited to”.
    The inventive device for protecting edges comprises a first edge protection profile and / or a second edge protection profile, wherein the first edge protection profile is intended to rest on a first edge and / or the second edge protection profile is intended to rest on a second edge. The first and / or second edge protection profile can be held in a defined position on the first and / or second edge by means of a clip. Such edges can, in particular, run vertically, for example include edges of walls, in particular exposed concrete walls. The edges can also run in the horizontal direction or have an angle of inclination with respect to the horizontal direction that is greater than 0 degrees and less than 90 degrees. The edges can be flat or curved. A curved course can occur, for example, with archways. In particular, a first edge and a second edge are provided. The first edge can run parallel to the second edge. The first and second edges can delimit an end face of a wall. According to one exemplary embodiment, the first edge is formed by a first side surface of the wall and the end surface. According to one exemplary embodiment, the second edge is formed by a second side surface of the wall and the end surface. The first edge protection profile and / or the second edge protection profile and the clip are components of an edge protection system which makes it possible to temporarily protect existing edges against damage, for example while carrying out conversion work, renovations, cleaning work or the like.

B. Caprolactam available. Examples of such polyamides are PA 4 (made up of 4-aminobutyric acid), PA 6 (made up of 6-aminohexanoic acid). For example, PA 11 is a polyundecanolactam and PA 12 is a polydodecanolactam. In the case of polyamides which, as in this case, are composed of only one monomer, the number after the abbreviation PA indicates the number of carbon atoms in the monomer.
    Polyamides can optionally be prepared with an elastomer as a modifier. Suitable copolymamides are, for example, block copolymers of the above-mentioned polyamides with polyolefins, olefin copolymers, ionomers or chemically bonded or grafted elastomers; or with polyethers, for example with polyethylene glycol, polypropylene glycol or polytetramethylene glycol; as well as polyamides or copolyamides, modified with EPDM or ABS; and polyamides condensed during processing (RIM polyamide systems).
