Abstract
A handle can be fastened to a main body by way of screws and includes a main profiled part having two receiving portions and at least two slot nuts, which each have a threaded hole for receiving one of the screws. One slot nut each is inserted in a receiving portion and can be clamped in the receiving portion when a screw, which passes through the main body, is screwed into the threaded hole. The clamping of the slot nuts generates tensile stresses which pull the main profiled part in the direction of the surface of the main body and thus secure the main profiled part to the main body.
Claims14
A handle for attachment to a main body by means of screws, comprising:
- a main profiled part having two end portions, each end portion having a respective receiving portion at the respective end portion of the main profiled part, wherein the receiving portions extend so as to be inclined to one another;
- and
- two slot nuts, which have respective threaded holes for receiving the screws, wherein each of the slot nuts is made to be slidably inserted in the respective receiving portion, and wherein at least part of the outer profile cross-section of the slot nuts corresponds in shape to and mates with respective inner profile cross-sections of the receiving portions;
- wherein the handle can be rigidly fixed to the main body when each of the slot nuts is slidably inserted in the respective receiving portion and is rigidly fixed to the main body by the respective screw, which passes through the main body, being screwed into the respective threaded hole of the respective slot nut, such that tensile stresses are generated in the direction of a surface of the main body and the main profiled part is clamped between the rigidly fixed slot nuts,
- wherein
- the receiving portions extend so as to be inclined opposite and away from one another and each receiving portion extending so as to be inclined with respect to an insertion direction of the respective screw, and
- the tensile stresses have components which act in directions which are opposite to one another and extend in parallel to the surface of the main body.

A handle for attachment to a main body by means of screws, comprising:
- a main profiled part having two end portions, each end portion having a respective receiving portion at the respective end portion of the main profiled part, wherein the receiving portions extend so as to be inclined to one another;
- and
- two slot nuts, which have respective threaded holes for receiving the screws, wherein each of the slot nuts is made to be slidably inserted in the respective receiving portion, and wherein at least part of the outer profile cross-section of the slot nuts corresponds in shape to and mates with respective inner profile cross-sections of the receiving portions;
- wherein the handle can be rigidly fixed to the main body when each of the slot nuts is slidably inserted in the respective receiving portion and is rigidly fixed to the main body by the respective screw, which passes through the main body, being screwed into the respective threaded hole of the respective slot nut, such that tensile stresses are generated in the direction of a surface of the main body and the main profiled part is clamped between the rigidly fixed slot nuts,
- wherein
- at least one of the slot nuts has a trapezoidal longitudinal section, and a corresponding receiving portion which receives the slot nut in slidable fashion, also has a trapezoidal longitudinal section which corresponds to the trapezoidal longitudinal section of the slot nut.
