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.

First claim

The invention claimed is:

1. 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.

2. The handle according to claim 1 , wherein
the two end portions of the main profiled part include a first end portion and a second end portion, wherein the first and second end portions extend so as to be inclined towards one another,
wherein one of the slot nuts is mounted to be slidable in the first end portion of the main profiled portion and wherein the other one of the slot nuts is mounted to be slidable in the second end portion of the main profiled part.

3. The handle according to claim 2 , wherein
the main profiled part has a first bend and a second bend and the first end portion is located in a region of the first bend and the second end portion is located in a region of the second bend.

4. 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.

5. The handle according to claim 4 , wherein
the threaded hole extends through the at least one slot nut from a first side of the trapezoid to a second side of the trapezoid, said second side being opposite to the first side, such that the direction of the threaded hole and a third side and a fourth side of the trapezoid, said fourth side being opposite thereto, in each case enclose an angle of more than 0.

6. The handle according to claim 5 , wherein
the direction of the threaded hole and the third side and the fourth side of the trapezoid, said fourth side being opposite thereto, in each case enclose an angle of less than 90 degrees.

7. The handle according to claim 5 , wherein
the direction of the threaded hole is substantially aligned at a perpendicular angle to the first side of the trapezoid.

8. The handle according to claim 5 , wherein
in the fastened state the slot nuts are secured by means of the screws screwed into the threaded holes so as to face the main body by means of the first side of the trapezoid shape of the slot nuts, such that longitudinal directions of the trapezoid shape of the slot nuts are inclined towards one another and the main profiled part is clamped between the slot nuts by means of the third and fourth sides of the trapezoid shape of the two slot nuts.

9. 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 three sides of a longitudinal section of one of the receiving portions have a first trapezoid shape, wherein a first side of the first trapezoid shape corresponds to an opening of the main profiled part at the end and the at least three sides of the first trapezoid shape furthermore comprise a third side and a fourth side of the first trapezoid, said fourth side being opposite thereto, and the third and fourth sides of the first trapezoid shape correspond to wall portions of the receiving portion.

10. The handle according to claim 9 , wherein
the slot nut can be inserted in the corresponding receiving portion through the opening of the main profiled part at the end and is mounted to be slidable in the corresponding receiving portion in the direction of the parallel extending second and third sides of the first and/or second trapezoid form.

11. The handle according to claim 9 , wherein
the direction of the threaded hole is aligned substantially at a perpendicular angle to the first side of the first and/or second trapezoid; and
the direction of the threaded hole and the third side and the fourth side of the first and/or second trapezoid, said fourth side being opposite thereto, in each case enclose an angle of more than 0 and/or less than 90 degrees.

12. 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 porti
