DETAILED DESCRIPTION
[0038] FIG. 1 shows a preferred configuration of the proposed power tool 1. The power tool 1 illustrated in FIG. 1 has a front, circumferential handle, and a rear handle. The handles enclose a main body of the power tool 1, which is surrounded by a housing 11. Furthermore, the power tool 1 has a tool 2 (shown solely schematically), wherein the protective hood of the tool 2 is representatively denoted by reference sign 112 in FIG. 1. The power tool 1 illustrated in FIG. 1 is a cut-off grinder which is preferably configured to introduce cuts into hard materials, such as concrete and steel. The tool 2 of such a cutoff grinder 1 is conventionally disk-shaped and is referred to as a cutting disk.
[0039] The front circumferential handle and the rear circumferential handle of the power tool 1 preferably define the spatial directions front and rear, and also front side and rear side. For the purposes of the invention, it is preferred that the main body of the power tool 1 has a front side which is arranged in the region of the front circumferential handle of the power tool 1. This front side of the main body of the power tool 1 is preferably arranged in such a manner that it faces the tool 2 of the power tool 1. In the lower region of said main body of the power tool 1 there is the preassembled assembly 10 which comprises in particular a guard plate 3 and standing feet 4 (see, e.g., FIG. 3). The preassembly of the assembly 10 consists in that the standing feet 4 are pushed onto tabs 5 of the guard plate 3 such that they are held by the guard plate 3. For this purpose, the standing feet 4 can have slots 8 (see, e.g, FIG. 4) which are configured in such a manner that they can receive the lateral tabs 5 of the guard plate 3. The preassembled assembly 10 consisting of guard plate 3 and standing feet 4 can be fastened to the power tool 1 in a particularly simple and uncomplicated manner. The standing feet 4 are produced from an elastic material, such as rubber, or comprise such an elastic material. Owing to the elasticity of the material of the standing feet 4, the power tool 1 which is provided with the assembly 10 has a secure and stable standing position and can be placed in a particularly slip-proof manner on a substrate.
[0040] The guard plate 3 has an L shape with a front portion 6 and a lower portion 7, wherein the front portion 6 and the lower portion 7 of the guard plate 3 enclose an angle which is substantially a right angle with each other. This angle may be for example 85 degrees, 90 degrees or 93 degrees. For the purposes of the invention, it is preferred that, in the mounted state, the front portion 6 of the guard plate 3 is arranged on the front side of the main body of the power tool 1, while, in the mounted state, the lower portion 7 of the guard plate 3 is arranged on a bottom side of the power tool 1.
[0041] FIG. 2 shows a preferred configuration of the bottom side of the proposed power tool 1. In particular the lower portion 7 of the guard plate 3 can be seen, wherein it is in particular this lower portion 7 of the guard plate 3 on which the tabs 5 are arranged for fastening the standing feet 4. This is illustrated in particular also in FIG. 3. It is moreover shown in FIG. 2 that the guard plate 3 can be fastened to the power tool 1 or to the housing 11 thereof with two fastening screws. The tool 2 of the power tool 1 or the protective hood 112 thereof can be seen in the left, lower region of FIG. 2.
[0042] FIG. 3 shows a preferred configuration of the guard plate 3 with standing feet 4 (at the bottom) and without standing feet 4 (at the top). The upper part of FIG. 3 shows the guide plate 3 with its componentsfront portion 6, lower portion 7 and the tabs 5, which are preferably located on the lower portion 7 of the guard plate 3, specifically preferably on the sides of the lower portion 7. In particular, the upper part of FIG. 3 shows the guard plate 3 with the lateral tabs 5 for fastening the standing feet 4. The lower part of FIG. 3 shows the assembly 10 fully preassembled, wherein the standing feet 4 are already fastened to the tabs 5 of the guard plate 3 here. The standing feet 4 can have slots 8 with which the standing feet 4 can be pushed over the tabs 5 of the lower portion 7 of the guard plate 3. FIG. 3 therefore shows the preassembling of the standing feet 4 by pushing the standing feet 4 onto the tabs 5 of the guard plate 3. The preassembled assembly 10 is thereby obtained. The guard plate has beads 12 for increasing the flexural rigidity of the guard plate and a circular arc surface 13 usable as a rolling surface.
[0043] FIG. 4 shows a preferred configuration of the standing feet 4 with their slots 8 into which the tabs 5 of the guard plate 3 can be inserted.
[0044] FIG. 5 shows a preferred configuration of the assembly 10 in the mounted state on the power tool 1. The guard plate 3, or the front portion 6 and the lower portion 7 of the guard plate 3, and the standing feet 4 can be seen. In particular, FIG. 5 provides a view of a preferred configuration of the bottom side of the proposed power tool 1.
[0045] FIG. 6 shows a preferred configuration of the mating contour 9 on the housing 11 of the power tool 1. The mating contour 9 is preferably present on the bottom side of the power tool 1. For the purposes of the invention, it is preferred that the mating contour 9 is raised and is configured for fastening the guard plate 3 of the power tool 1. For the purposes of the invention, it is very particularly preferred that the mating contour 9 is formed by a circumferential raised wall on the housing 11 of the power tool 1. This wall advantageously ensures that the standing foot 4 is guided laterally in the housing 11.
[0046] FIG. 7 shows a preferred configuration of the standing feet 4 with which a particularly secure and stable standing position of the power tool 1 can be achieved. Furthermore, the slip resistance of the power tool 1 can be substantially improved by the standing feet 4. A significant advantage of the invention consists in that the mounting of the standing feet 4 on the power tool 1 can be considerably simplified and made more rapid by the standing feet 4 being preassembled on the guard plate 3, wherein the preassembling of standing feet 4 and guard plate 3 makes it possible to obtain the proposed assembly 10. The left side of FIG. 7 shows more detail of the mating contour 9.
[0047] FIG. 8 shows a preferred configuration of the assembly 10 in the state not mounted on the power tool 1. The assembly 10 which is illustrated in FIG. 8 is preassembled in the sense that the standing feet 4 are mounted on the lateral tabs 5 of the guard plate 3. However, the assembly 10 obtained in this manner is not mounted on the power tool 1, and therefore the corresponding state is referred to as not mounted.
