The invention relates to handle which can be fastened to a main body.
Handles are used for a plurality of different purposes. For example, a door/flap of a machine tool can be provided with a handle, by means of which a person can open the door/flap. In this connection, a handle is desirable which has a simple design and can simultaneously be mounted with little effort and, after fastening it to a main body, is secured in rigid and stable fashion.
A handle according to one exemplary aspect can be fastened to a main body by means of screws and comprises a main profiled part having at least 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 (which can also be referred to as a groove stone) can be 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 can generate 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.
In particular, a handle is exemplarily proposed which has a main profiled part with two receiving portions at the end, wherein the receiving portions preferably extend so as to be inclined towards one another, and at least two slot nuts which each have respective threaded holes for receiving the screws, wherein each of the slot nuts is designed or formed so as to be inserted in a respective receiving portion and wherein an at least part of the outer profile cross-section of the slot nuts is adapted to the respective inner profile cross-sections of the receiving portions.
Exemplarily, the handle is rigidly securable to the main body by inserting each of the slot nuts in a respective receiving portion and by fastening it in the respective threaded hole when a respective screw, which passes through the main body, is screwed in, such that the main profiled part is clamped between the rigidly secured slot nuts, wherein, where applicable, tensile stresses are exerted in the direction of the surface of the main body on the main profiled part at least while the screws are screwed in.
Due to the use of slot nuts having threaded holes, the design of the handle can be simple and the assembly of the handle to the main body can be simple.
When the handle is mounted, the slot nuts are advantageously aligned opposite to the receiving portions in such a way that the tensile stresses have components which act in directions that are opposite to one another and run in parallel to a surface of the main body. In this way, it is possible to improve the inherent rigidity of the handle and the stability of the attachment to the main body.
The main profiled part can have a first end portion and a second end portion, wherein at least one slot nut is mounted to be slidable in the first end portion and wherein at least one slot nut is mounted to be slidable in the second end portion. Therefore, the slot nuts can be inserted in, or removed from, the main profiled part in a simple way.
The main profiled part can have a first bend and a second bend. The first end portion can here be located in an area of the first bend and the second end portion can be located in an area of the second bend. As a result, the handle can be produced in a particularly simple way since the entire main profiled part can hence be made in one piece.
At least one slot nut can have a trapezoidal cross-section, and a corresponding receiving portion, which receives the slot nut so as to be slidable, can also have a trapezoidal cross-section which corresponds to the trapezoidal cross-section of the slot nut. Particularly good clamping of the slot nut in the main profiled part is ensured by the trapezoidal cross-section.
This is in particular the case when 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 (preferably perpendicularly 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 to the third side, in each case enclose an angle of more than 0 and/or less than 90°. The threaded hole can here run fully through the slot nut from the first side to the second side or up to a threaded end in the slot nut interior.
The handle can advantageously be designed as follows: In the region of a first end, the main profiled part can have a first hollow body-like portion (part of the first bend) and in the region of the second end a second hollow body-like portion (part of the second bend), wherein a first side region (surface region) of the first hollow body-like portion, said first side region facing a surface of the main body, and the surface form an angle of more than 90° and a second side region (surface region) of the second hollow body-like portion, said second side region facing the surface, and the surface form an angle of less than 90°.
The first slot nut can be mounted to be slidable in the first hollow body-like portion, and the second slot nut can be mounted to be slidable in the second hollow body-like portion. A first screw can be connected to the first slot nut by means of a threaded hole in the first slot nut, into which the first screw can be screwed, in order to fasten the first slot nut on the surface, and a second screw can be connected to the second slot nut by means of a threaded hole in the second slot nut, into which the second screw can be screwed, in order to fasten the second slot nut on the surface.
When the first screw is connected to the first slot nut, a force is exerted on the first slot nut and presses the first slot nut in the direction of the surface against the first side region, and when the second screw is connected to the second slot nut, a force is exerted on the second slot nut and presses the second slot nut in the direction of the surface against the second side region.
A side (“bottom side”) of the first slot nut/second slot nut, said side facing the surface of the main body, can be aligned parallel to the surface when the first slot nut/second slot nut is connected to the first screw/second screw.
The bottom side of the first slot nut/second slot nut can be flush with the first end/second end of the main profiled part when the first slot nut/second slot nut is connected to the first screw/second screw. It is thus possible to increase the surface area by means of which the main profiled part rests on the surface of the main body, as a result of which dents on the surface of the main body can be avoided.
The threaded hole in the first slot nut/second slot nut can be aligned perpendicularly to the bottom side of the first slot nut/second slot nut. Furthermore, the threaded hole can be aligned perpendicularly to the surface of the main body when the first slot nut/second slot nut is connected to the first screw/second screw.
A bush can be provided for each screw and penetrates, and is attached to, the main body, wherein each screw can be inserted in the appropriate bush and wherein the screw can be inserted by means of an end facing the main profiled part in the threaded hole of the appropriate slot nut and has a stop at an end facing away from the main profiled part, said stop striking a bush end facing away from the main profiled part when the screw is inserted in the bush. In this embodiment, the bottom side of the first slot nut/second slot nut can rest on a bush end facing the main profiled part when the first slot nut/second slot nut is connected to the first screw/second screw. Since the main profiled part/the first slot nut/second slot nut do thus not necessarily have to rest on the main body, dents on the surface of the main body can be avoided, where applicable.
The first hollow body-like portion/second hollow body-like portion and the first slot nut/second slot nut can be designed in such a way that the first slot nut/second slot nut can slide in the first hollow body-like portion/second hollow body-like portion in a direction which is inclined with respect to the surface but when connected to the first fastening element/second fastening element is pulled in a direction which intersects the first side region (surface region)/second side region (surface region). As a result, the first slot nut/second slot nut is pressed against the first side region/second side region, which is necessary to generate the tensile stresses.
The cross-sectional profile of the basic profile can be designed in the central region in a way that differs from that of the bends, e.g. such that the slot nuts cannot slip through the central region of the main profiled part. Therefore, the assembly of the handle can be simplified.
According to a useful embodiment, the main profiled part has a first end portion which includes one of the receiving portions and a second end portion which includes the other receiving portion, wherein the end portions extend so as to be inclined towards one another, and wherein, prior to the fastening by means of the screws, one of the slot nuts is mounted to be slidable in the first end portion of the main profiled part after the insertion and wherein, prior to the fastening by means of the screws, the other one of the slot nuts is mounted to be slidable in the second end portion of the main profiled part after the insertion.
Here, it is also preferred that at least three sides of a longitudinal cross-section (in particular in a plane perpendicular to the profile cross-section and/or perpendicular to the surface of the main body) of one of the receiving portions has 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 also have a third side and a fourth side of the first trapezoid, said fourth side being opposite to the third side, and the third and fourth sides of the first trapezoid shape correspond to wall portions of the receiving portion.
At least three sides of a longitudinal cross-section (in particular in a plane perpendicular to the profile cross-section and/or perpendicular to the surface of the main body) of one of the slot nuts preferably have a second trapezoid shape, wherein a first side of the second trapezoid shape has a threaded hole and the threaded hole runs from the first side of the second trapezoid to a second side of the slot nut, said second side being opposite to the first side, and the at least three sides of the second trapezoid shape furthermore comprise a third side and a fourth side of the second trapezoid, said fourth side being opposite thereto.
The slot nut can preferably 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 after the insertion in the direction of the parallel extending second and third sides of the first and/or second trapezoid shape.
The direction of the threaded hole is preferably 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 preferably 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 (alpha) of more than 0 and/or less than 90 degrees.
When fastened, the slot nuts are preferably secured by means of the screws screwed into the threaded holes via the first side of the trapezoid shape of the slot nuts so as to face the main body, 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.
According to a further, particularly useful embodiment, a first one of the slot nuts can be inserted in a first one of the receiving portions at the end, such that the first slot nut is slidable in the first receiving portion in a first direction of the receiving portion (and more preferably only slidable in the first direction, i.e. cannot be rotated and/or is blocked in positive fashion in other directions transversely to the first direction). Furthermore, a second one of the slot nuts can also preferably be inserted in a second one of the receiving portions at the end, such that the second slot nut is slidable in the second receiving portion in a second direction of the receiving portion (and more preferably is only slidable in the second direction, i.e. cannot be rotated and/or is blocked in positive fashion in other directions transversely to the second direction).
The first direction and the second direction are preferably inclined towards one another. This blocks the handle or the main profiled part in the fastened state, which is rigid and clamped between the slot nuts by positive engagement, as soon as both slot nuts which are received in the receiving portions are secured to the main body by means of the screws.
The first direction and the second direction preferably enclose an angle (on the side of the main body) of substantially between 30 and 120 degrees, more preferably an angle between 50 and 100 degrees.
Exemplary aspects of the invention are explained in more detail below in an exemplary embodiment with reference to the drawings.
In the figures, identical or matching areas, components or component assemblies are designated by the same reference signs.
One slot nut 6 each is inserted in a receiving portion 5 and can be clamped in the receiving portion 5 when a screw 3, which passes through the main body 2, is screwed into the threaded hole 7. The clamping of the slot nuts 6 generates tensile stresses Z which pull the main profiled part 4 in the direction of the surface 8 of the main body 2 and thus secure the main profiled part to the main body 2.
A simple design of the handle 1 and a simple assembly of the handle 1 on the main body 2 are possible by the use of slot nuts 6 having threaded holes 7.
When the handle 1 is mounted, the slot nuts 6 are advantageously aligned with respect to the receiving portions 5 in such a way that the tensile stresses include components Z1, Z2, which act in directions which are opposite to one another and extend parallel to the surface 8 of the main body 2. In this way, the inherent rigidity of the handle 1 and the stability of the attachment to the main body 2 can be improved and the handle can be rigidly clamped between the slot nuts 6.
As shown in
The main profiled part 4 has a first bend 11 and a second bend 12. The first end portion 9 is here located in a region of the first bend 11 and the second end portion 10 in a region of the second bend 12. As a result, the handle 1 can be produced in a particularly simple way since the entire main profiled part 4 can thus be produced in one piece.
In a side view of the handle 1, i.e. in the viewing direction of
A corresponding receiving portion 5, which receives the slot nut 6 so as to be slidable, has in a side view, i.e. in the viewing direction of
A particularly good clamping effect of the slot nut 6 is ensured in the main profiled part 4 by the cross-section which has a trapezoidal shape at least on three sides. This is the case in particular when the threaded hole 7 extends through the slot nut 6 from a first side 13 of the trapezoid to a second side 14 of the trapezoid, said second side being opposite to the first side, such that the direction of the threaded hole 7 and a third side 15 and a fourth side 16 of the trapezoid, said fourth side being opposite thereto, in each case enclose an angle alpha>0 (and preferably also less than 90°) (i.e. does not run parallel to the third side 15 and the fourth side 16).
As shown in
In the fastened state according to
Since the upper slot nut 6 in
In the exemplary embodiment according to
The first slot nut 6 is mounted to be slidable in the first hollow body-like portion 21, and the second slot nut 6 is mounted to be slidable in the second hollow body-like portion 22. A first screw 3 can be connected to the first slot nut 6 by means of a threaded hole 7 in the first slot nut 6 into which the first screw 3 can be screwed, in order to fasten the first slot nut 6 on the surface 8, and a second screw 3 can be connected to the second slot nut 6 by means of a threaded hole 7 in the second slot nut 6, into which the second screw 3 can be screwed, in order to fasten the second slot nut 6 on the surface 8. When the first screw 3 is connected to the first slot nut 6, a force Z is exerted on the first slot nut 6 and presses the first slot nut 6 against the first side region 19 in the direction to the surface 8, and when the second screw 3 is connected to the second slot nut 6, a force Z is exerted on the second slot nut 6 and presses the second slot nut 6 against the second side region 20 in the direction of the surface 8.
In
As is disclosed in
As shown in
In this exemplary embodiment, the bottom side 13 of the first slot nut/second slot nut 6 can rest on an end 28 of the bush 23, which faces the handle body, when the first slot nut/second slot nut 6 is connected to the first screw/second screw 3. Therefore, the main profiled part 4 does not have to rest directly on the surface 8 of the main body 2, as a result of which the surface 8 can be made from a sensitive material without being damaged when the handle 1 is fastened. For example, as shown in
The first hollow body-like portion 21/second hollow body-like portion 22 and the first slot nut/second slot nut 6 can be designed in such a way that the first slot nut/second slot nut 6 can slide in the first hollow body-like portion 21/second hollow body-like portion 22 in a direction R1/T2, which is inclined with respect to the surface 8, but when it is connected to the first screw/second screw 3, it is pulled in a direction R3 which intersects the first side region 19/second side region 20.
The cross-section of the main profiled part 4 in a central region 30 can be different from the region of the bends 11, 12, such that the slot nuts 6 cannot slip through the central region 30 of the main profiled part 4. Therefore, the assembly of the handle 1 can be simplified since the first slot nut/second slot nut 6 cannot travel from the hollow body-like portions 22/23 to the central region 30.
Although the profile of the slot nut 6 according to
Finally,
In summary, it is possible to provide by means of the invention a handle which can easily be produced, which has a simple design with only some few individual parts and can simultaneously be mounted with little effort and, after the attachment, is secured rigidly and in stable fashion to a main body.
