Definitions
- the invention relates to a tool for smoothing surfaces with a substantially flat working surface formed by a base and a handle arranged on the side of this base facing away from this working surface.
- Such tools are used for smoothing surfaces of all kinds, e.g. used as grinding and polishing tools, as rasps, but also for rubbing coating materials such as mortar, putty, etc.
- the invention is to design the handle of such a tool so that the fingers of the user's hand can rest as comfortably as possible on the side of the tool base intended for this, so that the risk of cramping the fingers even with long-term uninterrupted use of the tool is reliably prevented.
- the invention is based on the knowledge that thanks to this design and arrangement of the handle all fingers of the hand of the user can remain stretched while using the tool, so that the risk of cramping the fingers is largely eliminated from the outset.
- the projection has, according to a preferred embodiment of the invention, concavely rounded flanks and / or end faces, in order to offer the thumb and the index finger favorably designed contact surfaces.
- the projection is expediently arranged along a side edge of a base which is raised in relation to the plate-shaped base and arranged centrally on the upper side of this base, on the flank of which is adjacent to the projection Thumb and the other fingers of the hand can be placed on the top of this base adjoining the projection.
- the fingers that can be placed on the top of this base can thus comfortably exert pressure on the tool together with the thumb and forefinger, namely in the stretched state.
- the upper side of the base which serves as a support for the fingers of the hand, projects beyond the lower part of the base with an edge strip on its three projection-free side edges.
- the tool can be made from any material, but it has proven to be advisable to make the tool in one piece, from a flexible, preferably elastically flexible, material, e.g. a plastic, such as polyurethane.
- a flexible, preferably elastically flexible, material e.g. a plastic, such as polyurethane.
- a plastic such as polyurethane.
- Such a tool is particularly suitable for adapting various surface designs of the workpieces or components to be machined, with the additional fact that thanks to the design of the handle according to the invention with all fingers of the user, i.e. practically with the whole hand, a desirable deformation and adaptation of the resilient tool has been brought about can be.
- the tool shown in the single drawing figure for example, and explained below, has an approximately rectangular and plate-shaped base 1 with an essentially flat working surface 2, on which, if necessary, in a manner known per se and for the present Inessential manner, for example by adhesion, gluing or by means of fastening elements mechanically, a grinding or polishing material 3 can be fastened.
- the handle On the side facing away from the work surface 2 (upper side) of the base 1, the handle is arranged, which essentially extends as an eccentric, that is to say along a side edge, extending, elongated, between the thumb 4 and the index finger 5 of a hand is formed with concave flanks 6 and end faces 7 designed projection 8.
- This projection 8 is provided along a side edge of a base 9 which is raised relative to the base 1 and is arranged centrally on the upper side of this base 1, on the flank 6 of which together with the projection 8 the thumb 4 and on its adjoining this projection 8 Top 10, the remaining fingers 5, 11, 12 and 13 of the hand of the tool user can be placed.
- the projection protrudes from the base 9 starting at an acute angle ⁇ , preferably approximately 45 ° upwards and outwards from the base 1, so that the thumb 4 - corresponding to the formation of the human hand - on the flank 6 in can lie at a lower level than the other fingers 5, 11, 12 and 13.
- the top 10 of the base 9, which serves as a support for these remaining fingers, projects beyond the three protrusion-free side edges of the lower part of the base 9 with an edge 14 which improves the grip of the base 9 for these remaining fingers 5, 11, 12 and 13 serves.
- the upper side 10 of the base 9 rises upwards against the protrusion 8 protruding from this upper side 10 at an angle ⁇ of approximately 5 to 10 °. This design also improves the handling of the tool by taking into account the normal position of the human hand.
