The present disclosure relates to a shaped component, to a method for connecting of at least one sheet metal component to a shaped component, and to a system of a sheet metal construction at least comprising a first sheet metal component and at least one shaped component.
The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
Shaped components intended for connecting of sheet metal components, in particular of cable ducts, are generally known from the prior art. Document DE 20 106 642 U1, for example, describes an apparatus for connecting of trough-shaped shaped components which are designed as having a U-shaped cross section and whose leg near the base of the U-shape features inward-extending ribbing progressing in the longitudinal direction of the shaped component. The connectors herein are designed as flat plates which feature a solid longitudinal ribbing in the vicinity of a longitudinal border. These connectors are connected by screws to two shaped components joined end to end.
Document WO 00/04295 A1 describes a connection for sheet metal parts positioned perpendicular to each other. By twisting a tab protruding past one edge of the sheet metal part, the sheet featuring the tab is tensioned with a sheet metal part arranged perpendicular thereto and featuring a corresponding opening.
The disadvantage of the connections of sheet metal parts known from the prior art is that a screw connection requires a significant effort for its installation. Furthermore, due to the additional parts required in this regard, the screw connections are cost-intensive, especially in regard to larger projects.
This section provides a general summary of the disclosure and is not a comprehensive disclosure of its full scope or all of its features.
In one form of the present disclosure a shaped component includes a main metal sheet and at least one torsion tab. The torsion tab features or includes a torsion region and a tab head, and an extension of the torsion region perpendicular to a center longitudinal axis of the torsion tab is smaller or less than an extension of the tab head perpendicular to the center longitudinal axis of the torsion tab. Also, the tab head comprises a clamping region and the torsion tab protrudes from a main metal sheet plane.
In another form of the present disclosure, a method for connecting at least one first sheet metal part with a shaped component includes guiding at least one first torsion tab of the shaped component through a first recess of a first sheet metal part, twisting the first torsion tab by about 10° to about 170° about its central longitudinal axis, and a tab head of the torsion tab cooperates with the first sheet metal part such that the tab head tensions the first sheet metal part with a main metal sheet of the shaped component. As used herein, the term “tensions” refers to holding or clamping together at least two parts together.
In still another form of the present disclosure, a system of a sheet construction includes a first sheet metal part and at least one shaped component with at least one torsion tab of the at least one shaped component extending through at least one recess of the first sheet metal part. The at least one torsion tab is twisted by about 10° to about 170° about its center longitudinal axis such that a tab head of the at least one torsion tab cooperates with the first sheet metal part such that a main metal sheet of the shaped component is tensioned or held into contact with the first sheet metal part.
Now whereas the term “about” is used in conjunction with the present disclosure when referring to values or value ranges, then this is intended to mean a tolerance range which the skilled person in this field will deem as common and usual, in particular a tolerance range of ±20%, preferably ±10%, more preferably ±5% is meant.
A shaped component comprising a main metal sheet and at least one torsion tab is provided, wherein the at least one torsion tab has a torsion region and a tab head. An extension of the torsion region perpendicular to a center longitudinal axis of the torsion tab is smaller or less than an extension of the tab head perpendicular to the center longitudinal axis of the torsion tab, and the tab head comprises a clamping region.
In some variations of the present disclosure, the shaped component is made from sheet metal. Non limiting examples of materials for making the shaped component include steel, stainless steel, aluminum, tin plate, copper and brass, among others. In other variations, the shaped component comprises a synthetic material, in particular a thermoplastic material and/or an intrinsically conducting plastic. In at least one variation the shaped component is at least partially coated with a plastic material. In some variations the shaped component is designed at least partly of plastic material. It should be understood that the term “sheet material” as used herein refers to any and all large-area materials being essentially flat, especially independently of the material of the large-area sheet.
In an additional form of the present disclosure the shaped component features at least one electric circuit path. In particular, the at least one electric circuit path is arranged such that at least it can be used to establish an electrically conducting connection with at least one sheet metal component. In an additional configuration the present disclosure provides that the shaped component, and preferably a material of the shaped component, is inherently electrically conducting. In an additional configuration the present disclosure provides that at least one surface is designed or configured as being at least partly electrically conducting. By means of an electrical conductivity of the shaped component, an electrically conducting connection can be established between at least one sheet metal component and the shaped component or between two shaped components. In particular, a compensation of potential can be created between sheet metal component and shaped component by an electrical connection. In an additional configuration the present disclosure provides that the shaped component features electrical properties corresponding to DIN EN 61537:2007 Standard, for example in connection with at least one additional shaped component and/or at least one sheet metal component. A compensation of potential and/or at least a connection to ground can be established by the shaped component. In an additional form the present disclosure provides that via the torsion tabs, a compensation of potential can be established, for example with the ground or between at least one sheet metal component and the shaped component or between two shaped components.
For example, an electrical conductance is provided between two metal-sheet components and the shaped component, or between two shaped components, which exhibits an impedance of less than or equal to 50 ma across a connection point, wherein an alternating current of 25 A±1 A is applied at a frequency of 50 Hz to 60 Hz from a voltage source, with a bias voltage of not more than 12 V, across the connection point of the two sheet metal components and the shaped component or between two shaped components, wherein a voltage drop is measured between two points which are located 50 mm distant from each side of the connection point. The connection point is in particular the overlap region of the shaped component with the sheet metal components or the two shaped components.
In some variations, the shaped component comprises a main metal sheet and the at least two torsion tabs, wherein the torsion tabs are formed from the main metal sheet, for example punched out, milled or sawn from the main metal sheet. In one configuration the torsion tabs are connected to the main metal sheet as a single piece. Within the meaning of the present disclosure, the term “main metal sheet” means a component or a section of a component which acts as the base for an additional component, but also a component or a section of a component from which an additional component is extracted and in particular is materially connected thereto. In one configuration the main metal sheet is a wall, an extension, or a bottom of a shaped component.
Within the meaning of the present disclosure, a “single piece” means that the parts are molded and/or produced essentially from one workpiece, i.e., two parts are essentially materially connected and/or formed from a single piece of material.
In one configuration the present disclosure provides that the at least one torsion tab is materially connected to the main metal sheet, that is, it is designed as a single piece. In particular, the at least one torsion tab is detached from, preferably punched out from a base material of the main metal sheet. It some variations the torsion tab is at least partly and/or at least simply bent.
The term “essentially” denotes a tolerance range which relates to financial and technical considerations for the skilled person, such that the corresponding feature can still be recognized and/or implemented as such.
In one configuration the present disclosure provides that the at least one torsion tab has a geometry which allows a twisting of the torsion tab, for example a twisting about a center longitudinal axis thereof. In another configuration the torsion region of the torsion tab is connected to the main metal sheet. In at least one variation an extension of the torsion region perpendicular to the center longitudinal axis amounts or is equal to about one-half, for example about ¼ or about ⅛ of an extension of the tab head perpendicular to the center longitudinal axis. In some variations, the present disclosure provides that the extensions perpendicular to the center longitudinal axis are also perpendicular to the material thickness of the torsion tab.
In some variations of the present disclosure the shaped component is manufactured from one part, or rather from one workpiece. The workpiece can be a sheet, for example a metallic sheet. In an additional configuration the present disclosure provides that the workpiece is stamped, for example at least in part to form the shaped component. In at least one variation, an outer contour of the shaped component is formed essentially by stamping. In another form, the shaped component has embossing. In one configuration the present disclosure provides that the torsion tab is punched out. In one configuration the torsion tab is materially locked to the main metal sheet. In particular, the torsion tab with the torsion region is disposed on the main metal sheet. In an additional form, the stamping of the torsion tab takes place such that the torsion tab with the torsion region is disposed on the main metal sheet.
In one configuration the present disclosure provides that the torsion tab is bent outward or is canted away from the plane of the main metal sheet.
In an additional configuration the present disclosure provides that the center longitudinal axis of the torsion tab relative to a plane of the main metal sheet has an angle of about 30° up to about 150°, for example about 80° up to about 100°, for example about 90°. According to the present disclosure the torsion tabs extend from the plane of the main metal sheet. The advantage of the torsion tab being bent outward from the plane of the main metal sheet is that this tab can be easily inserted into a corresponding recess, without the torsion tab having to be bent into an appropriate position, for example with the assistance of a tool.
Within the meaning of the present disclosure, the “plane of the main metal sheet” is understood to mean a plane which is parallel to the essentially planar main metal sheet or to an essentially planar main metal sheet section. The plane of the main metal sheet is an essentially planar surface, or an essentially planar surface section of the main metal sheet.
In an additional form the present disclosure provides that the shaped component features two, for example four torsion tabs. In one configuration the two torsion tabs, e.g., their tab heads in an untwisted state, are arranged essentially parallel to each other. In an additional configuration the present disclosure provides that the two torsion tabs, e.g., their tab heads in the untwisted state, are arranged essentially not parallel to each other. In such a configuration the present disclosure provides that at least two torsion tabs, e.g., their tab heads in the untwisted state, can be arranged at an angle to each other of about 30° up to about 60°, for example about 45°. A non-parallel arrangement of the torsion tabs to each other has the advantage that a defined positioning of the shaped component is possible, for example, on a sheet metal component, especially when no positioners is provided.
In an additional configuration the present disclosure provides that the torsion tabs extend from the main metal sheet plane from the same side or from opposing sides of the main metal sheet. This can be used for connecting of components arranged in parallel. For example, in one configuration the present disclosure provides that on a first side of the main metal sheet a first metal-sheet component is mounted, and on a second side of the main metal sheet a second sheet metal component is mounted, so that the sheet metal components are attached to each other at a spacing of the material thickness of the main metal sheet in the region of the main metal sheet.
In another configuration, the shaped component is used to connect two sheet metal components together edge to edge. In this regard a first torsion tab is inserted into a recess of a first sheet metal component and a second torsion tab is inserted into an additional recess of a second sheet metal component. The torsion tabs are subsequently twisted, that is, they are twisted wherein a torsion is applied essentially in the torsion region and the twisting of the torsion tabs produces a positive-locking connection. In an additional configuration the present disclosure provides that the clamping region of the tab head upon twisting thereof acts on the sheet metal component such that the shaped component and/or the main metal sheet of the shaped component is clamped to the sheet metal components.
In another form of the present disclosure, clamping of the shaped component and the main metal sheet provides a secure electrically conducting connection. For example clamping provides a compensation of potential between the shaped component and the sheet metal component. In an additional form the present disclosure provides that an electrically conducting connection of the main metal sheet and/or of the torsion tab to the sheet metal component is provided which provides a reliable contact, especially due to the clamping.
The tab head features a clamping region. In particular, the tab head is divided into a clamping region and a grip area. In one configuration the tab head features a grip area which is designed such that it can be easily grasped with a tool opening of an additional, or another—perhaps also alternatively shaped—component, with an electrician's tongs and/or pliers.
In an additional configuration the tab head comprises essentially only one clamping region. The clamping region in one configuration is designed such that cheeks of the clamping region point essentially toward the main metal sheet, essentially or partially in an install situation of the shaped component indicated according to the present disclosure. In particular, in one configuration the present disclosure provides that the clamping region in the direction of the center longitudinal axis away from the torsion region features an increasingly greater extension perpendicular to a center longitudinal axis. In an additional configuration the present disclosure provides that at least one cheek, preferably at least in one section of the clamping region, has an angle to the plane of the main metal sheet of about 5° up to about 80°, for example about 7° up to about 60°, about 10° up to about 35°, or about 12° up to about 28°. In an additional form the present disclosure provides that at least one cheek, for example at least in one section of the clamping region, has an angle to the center longitudinal axis of the torsion tab from about 20° up to about 85°, for example about 30° up to about 83°, or about 62° up to about 78°, wherein the apex of the angle is allocated to the torsion region and the angle opens from the tab head in the direction of the main metal sheet. The torsion can be applied in any particular direction.
In some configurations, the torsion tab has a torsion region and a tab head. The tab head features an extension which is significantly broader or greater than an extension of the torsion region. In one form the tab head additionally also features a clamping region which broadens, for example consistently or continuously, proceeding from the torsion region in the direction of the center longitudinal axis and away from the torsion region. In at least one configuration, the cheeks of the clamping region are designed as being arranged straight in a longitudinal section in a top view. In one form, the cheeks feature an angle to the main metal sheet plane which amounts to about 10° up to about 30°. In another configuration the torsion region comprises a foot region which is in particular an angled and/or a curved section, wherein the foot region is materially connected or is connected as a single piece to the main metal sheet. Also, the foot region comprises a section which is arranged in the main metal sheet plane. In some configurations the present disclosure provides that a spring force, or a spring constant, of the torsion region, especially before and/or after a twisting thereof, is adjustable by a length of the foot region which is located in the main metal sheet plane. For example, slits in the main metal sheet are provided for the torsion region, e.g., for the foot region. In an additional configuration the foot region in the direction of the material-locking connection with the main metal sheet has a trapezoidal design. In particular, one base of the trapezoidal shape of the material-locking connection is assigned to the main metal sheet. In at least one configuration, the foot region, for example the portion of the foot region which is arranged in the main metal sheet plane, has a rectangular design.
In some variations the torsion region is that section of the torsion tab which is at least partly deformed by the twisting of the torsion tab about the center longitudinal axis. Depending on the torsion on the torsion tab, a deformation can also occur in the tab head, for example in the clamping region and/or in the region of the clamping region adjoining the torsion region. In one form the clamping region is designed such that after the torsion (e.g., twisting) of the torsion tab, the torsion tab has a distance (e.g., a maximum distance), at least in one partial region, which corresponds to an expected sheet thickness ‘b’ of the sheet metal component which is connectable to the shaped component. Accordingly, and due to the cheek of the clamping region arranged at an angle to the main metal sheet plane, different sheet metal components with different sheet thicknesses b can be connected to the shaped component.
Within the meaning of the present disclosure, a “cheek” of the clamping region is a surface extending over the material thickness of the tab head, for example extending perpendicular to an area extension of the torsion tab. In some variations the cheek extends between the torsion region and a region of the tab head which features essentially no enlarged extension in the direction of the longitudinal axis of the torsion tab away from the torsion region. In particular, the cheek of the clamping region can be the region of the tab head which acts (e.g., applies force) on a sheet metal component when the torsion tab is twisted. In one configuration the cheeks of the clamping region are designed such that they can apply a force onto a sheet metal component. In one additional configuration the present disclosure provides that the clamping region features cheeks which extend linearly in a longitudinal section. In one additional configuration the present disclosure provides that the cheeks are designed or configured as bent in a longitudinal section. In at least one variation, the clamping region features a material thickness that corresponds to the material thickness of the main metal sheet.
In at least one configuration the present disclosure provides that the tab head can be twisted. In some configurations the present disclosure provides that the torsion region can be twisted by twisting of the tab head. In at least one configuration the present disclosure provides that the clamping region can be twisted, at least in part, by twisting of the tab head.
Within the meaning of the present disclosure, a “torsion” means a twisting of a body or of a section of a body, which acts due to the effect of torque on this body or section of a body.
In some configurations the present disclosure provides that the torsion region and the tab head have essentially the same material thickness. In at least one configuration the present disclosure provides that the torsion region has a length in the direction of the center longitudinal axis of about 2 mm to about 15 mm, for example about 2 mm up to about 10 mm, about 2 mm up to about 6 mm, about 5 mm, among others. In some configurations the present disclosure provides that the torsion region has a length in the direction of the center longitudinal axis from about 0.5 times up to about 2 times the material thickness of the main metal sheet, for example about 0.5 times up to about 1.5 times the material thickness of the main metal sheet, about 0.5 times up to about one times the material thickness of the main metal sheet, about 0.5 times up to about three-quarters of the material thickness of the main metal sheet, about one-half the material thickness of the main metal sheet, among others.
Within the meaning of the present disclosure, the “material thickness” is understood to mean the thickness of the shaped component or of the sheet metal component at a particular location. In some variations the material thickness is essentially the same at each location of the shaped component. In at least one configuration the present disclosure provides that the material thickness at twisted and/or bent locations of the shaped component differs from the material thickness of a not bent or untwisted main metal sheet.
In one form the present disclosure provides that the torsion region is designed such that when under torsion it is shortened in the direction of the center longitudinal axis. In particular, the present disclosure provides that during an assembly of a sheet metal component with a greater material thickness, a torsion occurs about a smaller angle than for a sheet metal component with a smaller material thickness. Accordingly, the torsion tab in a sheet metal component with a greater material thickness is twisted less severely than for a sheet metal component with lesser material thickness in order to clamp the sheet metal component with the main metal sheet with an essentially equal force.
In some configurations the present disclosure provides that the torsion tab can be twisted with a torque of about 0.3 Nm up to about 5 Nm, for example about 0.5 Nm up to about 3 Nm, about 1.5 Nm up to about 2 Nm, among others, at about 45°. In some variations the tab head of the torsion tab can be twisted by about 45° with a torque of about 0.3 Nm up to about 5 Nm, for example about 0.5 Nm up to about 3 Nm, about 1.5 Nm up to about 2 Nm, among others.
In at least one configuration the present disclosure provides that the main metal sheet features at least one screw hole. The at least one screw hole in one variation is a solid opening having no threads. In another variation the at least one screw hole does have threads. In some configurations the present disclosure provides that the screw hole is assigned to one torsion tab. In particular, the screw hole is arranged in the vicinity of the torsion tab. In an additional configuration the present disclosure provides that the screw hole, in particular a section or point of the perimeter of the screw hole located nearest to the torsion tab, has a distance from the torsion tab, in particular from the torsion region, that is less than the radius of the screw hole. In some variations the present disclosure provides that a distance from a midpoint of the screw hole to the torsion tab is less than 1.5 times the diameter of the screw hole. Also, the screw hole is assigned to the torsion region of the torsion tab. In at least one variation the present disclosure provides that the distance of a midpoint of the screw hole to the untwisted torsion tab amounts or is equal to about one-half of a hex-head wrench width which correlates with a nominal diameter of the screw hole.
Within the meaning of the present disclosure the wrench width means the distance of two essentially parallel surfaces, in particular of a tool for transmission of torque, by positive locking. In at least one variation the wrench width is the nominal width of an Allen wrench for hex-head screws or nuts. The ratio of the rated diameter of the screw hole to the wrench width is defined in particular in the standard DIN EN 24014 in connection with the standard DIN EN 24017 dated February 1992. For example, at a rated diameter of the screw hole of 3 mm, a rated wrench width of 5.5 mm is provided; at a rated diameter of the screw hole of 5 mm, a rated wrench width of 8 mm is provided; at a rated diameter of the screw hole of 6 mm a rated wrench width of 10 mm is provided; and at a rated diameter of the screw hole of 8 mm, a wrench width of 13 mm is provided. In particular, the torsion tab is disposed with respect to the screw hole such that it acts as a torsion guard for a hex head screw or a nut.
In an additional configuration the present disclosure provides that an opening is formed by bending of the at least one torsion tab outward from the main metal sheet plane. In one form the present disclosure provides that the opening is designed as a screw hole. In particular, the opening is essentially round. In one configuration the opening features approximately a diameter that corresponds to a nominal diameter of a screw hole. In an additional form the present disclosure provides that the distance of a midpoint of the opening to the untwisted torsion tab amounts to about one-half of a hex-head wrench width which correlates with a nominal diameter of the opening. Furthermore, in one configuration the statements provided above regarding the at least one screw hole can be applied analogously to the opening.
In some configurations the present disclosure provides that the shaped component comprises at least one positioner. In at least one configuration the positioner is an elevation from the main metal sheet. In some configurations, the positioner extends from the main metal sheet. The present disclosure provides that the positioner extends beyond the main metal sheet by about 5% up to about 150%, for example about 20% up to about 120%, and about 80% up to about 100%, among others, of the material thickness of the main metal sheet perpendicular to the main metal sheet plane. In some configurations the present disclosure provides that the positioner is a part detached from, for example is punched out from the main metal sheet. In at least one configuration the positioning means is connected to the main metal sheet, for example by material-locking. In some configurations the positioner is connected to the main metal sheet as a single piece. In particular, the positioner is detached from the main metal sheet and is twice bent around (double bending), wherein an essentially planar surface is arranged essentially parallel to the main metal sheet plane. In at least one configuration the present disclosure provides that an essentially planar surface adjoins the doubled edging. In some configurations the at least one positioner is detached from the main metal sheet and is connected to the main metal sheet by a single bend.
In some configurations the present disclosure provides that the positioner features an extension that is designed as parallel to the main metal sheet plane. For example, the positioner features an extension from the main metal sheet progressing essentially parallel to the main metal sheet plane, in particular for a double bending. In other configurations the positioning means features an essentially angled extension progressing from the main metal sheet to the main metal sheet plane, in particular for a single bending.
In one configuration the present disclosure provides that the positioner features a surface which extends in the direction of the extension, wherein the surface of the positioner is parallel to a surface of the main metal sheet. In some configurations the present disclosure provides that the main metal sheet features a material thickness d which is essentially identical to the material thickness p of the positioner. Furthermore, the torsion tab in one form features a material thickness t which is essentially identical to the material thickness d of the main metal sheet.
In one form of the present disclosure, at least two, for example four, positioners are provided. In at least one configuration the present disclosure provides that the at least two positioning means are arranged as mirror-symmetrical to each other. Preferably the at least two positioners are arranged with respect to each other such that the angled sides, or rather the sides that are material-locked with the main metal sheet, point to of face each other. In some configurations the present disclosure provides that the at least two positioners are arranged with respect to each other such that the sides positioned opposite the angled sides point to or face each other.
In one variant of the shaped component the torsion tabs and also the positioners are located in the main metal sheet plane. In particular, the torsion tabs, the positioners, the screw holes and/or a material attenuation are detached from, and in particular are punched out from the main metal sheet in one work step. For example, a bending and/or edging of the torsion tabs and of positioners does not occur. A design of this kind reduces in particular the warehousing costs and shipping costs, since a molded part (e.g., a shaped component) punched out in this manner requires significantly less storage space. The positioners and/or the torsion tabs can each be bent out and mounted as needed at the installation site. That is, in some configurations a plurality of main metal sheets are punched such that the torsion tabs, the positioners, the screw holes and/or a material attenuation are formed from each main metal sheet, but bending and/or edging of the torsion tabs and of positioners does not occur. The plurality of punched main metal sheets are stored and/or shipped in this configuration and upon arriving at an installation site bending and/or edging of torsion tabs and positioners occurs as and when needed.
In some configurations the present disclosure provides that the main metal sheet between at least two torsion tabs comprises a material attenuation. In some variations the material attenuation is designed as a line, for example as a straight line. In at least one configuration the material attenuation features a plurality of recesses in the main metal sheet, which can be arranged in a straight line. In at least one configuration the present disclosure provides that the material attenuation is a single- or multiple-rolled and/or embossed region. For example, the material attenuation is arranged on an axis of symmetry of the main metal sheet. Also, bending of the main metal sheet along the material attenuation with a hand tool for example, or an edging of the main metal sheet along the material attenuation by use of a hand tool, for instance, is simplified. For example, if the shaped component is designed as a connector, then it can function as a corner connector in that the main metal sheet is edged preferably along the material attenuation. In some configurations the material attenuation is designed as a ribbing extending across the entire main metal sheet. In at least one configuration the present disclosure provides that the material attenuation is provided as a line-up of at least two, for example at least three, or at least four recesses extending all the way through the main metal sheet. In one form the recesses are rectangular, and in another configuration the recesses are round. In some configurations the present disclosure provides that the material attenuation features at least one, for example at least two, at least three, or at least four recesses, which are designed as not extending all the way through the main metal sheet. In at least one configuration the present disclosure provides that the material attenuation comprises a recess extending from a first edge of the main metal sheet to an opposing edge of the main metal sheet and which does not go all the way through. In some variations the material attenuation comprises a notch. In some configurations the present disclosure provides that the recess features a tapered cross section in the direction of the material thickness of the main metal sheet. For example, the cross section of the recess can be wedge-shaped. In at least one configuration the present disclosure provides that the material attenuation forms a deformation line. Along the deformation line a bending can be executed with a smaller torque than bending along a line across the main metal sheet that does not exhibit any material attenuation. Also, a deformation or bending of the main metal sheet can be implemented along the deformation line, for example, by using pliers to apply a torque on opposing sides of the material attenuation so that the main metal sheet will bend.
In one form of the present disclosure the shaped component is designed as a connecting element. In particular, the connecting element features a main metal sheet. In some configurations the main metal sheet comprises a surface that is arranged in a main metal sheet plane and two, four, or preferably six torsion tabs protrude from the main metal sheet. In at least one configuration positioners and screw holes are each associated with the torsion tabs. For example, one positioner and one screw hole each are allocated to each torsion tab. In at least one configuration the present disclosure provides that only one, only two, or only three torsion tabs are allocated to one positioner. In the alternative, the present disclosure provides that only every second or every third torsion tab is allocated to one positioner. In some configurations the present disclosure provides that one or a plurality of positioners are arranged on the main metal sheet, independently of one or of a plurality of torsion tabs. In at least one configuration, the torsion tabs extend essentially perpendicular to the main metal sheet plane and in the same direction from the surface of the main metal sheet. The positioners are elevated from the main metal sheet plane. Both the torsion tabs and also the positioners in one configuration are detached from or are punched out from the material of the main metal sheet. By bending the torsion tabs out from the main metal sheet plane, openings are produced which are allocated to the torsion tabs. For example, the present disclosure provides that the main metal sheet features a number of rectangular material attenuations which are arranged in a line, in particular a straight line. The material attenuations in one form separate one, two, three, or more than three torsion tabs or pairs of torsion tabs. In some configurations, the material attenuations are structured such that a slight bending along the deformation line created by the material attenuations is easily provided, for example, with a hand tool. In at least one configuration the present disclosure provides that the main metal sheet features four torsion tabs, and one screw hole and one positioner and/or the opening are allocated to each torsion tab. In some configurations the torsion tabs, the positioners and/or the screw holes are allocated to one corner of the main metal sheet.
In at least one configuration the torsion tabs are arranged upon the base pate such that every two torsion tabs are arranged mirror-symmetrical to each other, and the deformation line formed by the material attenuation forms the axis of symmetry. In some configurations the present disclosure provides that the openings from which the torsion tabs are bent out, are each arranged in the same direction relative to the torsion tabs. Furthermore, in at least one configuration the positioners are each allocated to the openings. For example, the configuration of the positioners is such that every two positioners are arranged along an axis of symmetry reflected on the main metal sheet. For example, the positioners feature tilting directed toward each other on one side of the deformation line. The tilting pertains to the sections of the positioners which are bent around such that the positioners extend from the base plane out over the main metal sheet. In some configurations, the tilting is of the section of the positioner which is connected to the main metal sheet material.
In some configurations the shaped component comprises four torsion tabs which protrude from a main metal sheet plane. The four torsion tabs are allocated preferably to the corners of the main metal sheet. In at least one configuration, every two torsion tabs are arranged centrally roughly between an axis of symmetry of the main metal sheet and an outer edge of the main metal sheet.
In some configurations, the shaped component features four torsion tabs and one material attenuation, which features a plurality of recesses in the main metal sheet, are arranged in a straight line, and on an axis of symmetry of the main metal sheet.
In at least one configuration, the present disclosure provides that the shaped component features four torsion tabs and four positioners. For example, the four positioners can each be associated with the four torsion tabs. Furthermore, in some configurations, the present disclosure provides that two positioners are associated with each one outer edge. In at least one configuration, the present disclosure provides that at least two positioners are associated with one corner of the main metal sheet. For example, four torsion tabs, four positioners and one material attenuation are provided.
In some configurations, the present disclosure provides that the shaped component features four torsion tabs and four screw holes. For example, the four screw holes are each associated with the four torsion tabs. Furthermore, in at least one configuration, the present disclosure provides that two screw holes are associated with each one outer edge. In one form, the present disclosure provides that at least two screw holes are associated with one corner of the main metal sheet. For example, four torsion tabs, four screw holes and one material attenuation are provided.
In at least one configuration, the present disclosure provides that the shaped component features four torsion tabs and four screw holes and four positioners. For example, the four screw holes and the four positioners are each associated with the four torsion tabs. Furthermore, in some configurations, the present disclosure provides that two screw holes and two positioners are associated with each one outer edge.

Furthermore, in at least one configuration the present disclosure provides that a torsion tab of an additional shaped component, arranged for example in the recess, can be twisted, by using and rotating of the alternative shaped component acting as tool.
In some configurations the present disclosure provides that a rotation of the alternative shaped component acting as tool, by an angle of about 30° up to about 50°, for example about 45°, causes a sufficient torsion of the torsion tab to connect and to clamp the shaped component to the sheet metal component in a positive-locking manner.

In still another form of the present disclosure, a method for connecting at least one first sheet metal component to a shaped component as described above is provided. At least one first torsion tab of the shaped component is guided through a first recess of the first sheet metal component, wherein the first torsion tab is twisted by about 10° up to about 170° around a center longitudinal axis of the torsion tab. A tab head of the torsion tab, for example a clamping region of the tab head, cooperates with the first sheet metal component such that the tab head, for example its clamping region, clamps the first sheet metal component with the main metal sheet of the shaped component. In some configurations the present disclosure provides that the recess is installed in the first sheet metal component before connecting of the shaped component to the sheet metal component. In at least one configuration the recess is installed in the sheet metal component which makes it possible to guide the torsion tab through the recess, wherein an extraction after the twisting of the tab head by about 10° up to about 170° around a center longitudinal axis of the torsion tab is inhibited or not possible.
In some configurations the torsion tab is twisted by an angle of about 30° up to about 120°, by about 40° up to about 100°, or by about 45°, among others. In at least one configuration the torsion tab is twisted such that a clamping region cooperates with the sheet metal component. In some configurations the present disclosure provides that the clamping region applies a force onto the sheet metal component during and/or after the torsion or twisting, respectively, of the tab head. In at least one configuration the present disclosure provides that the force corresponds to a spring force which is proportional to a spring constant of the torsion region, especially after the twisting.
In some configurations the present disclosure provides that at least one second torsion tab of the shaped component is guided through a second recess of a second sheet metal component, wherein the second torsion tab is twisted by about 10° to about 170° about its center longitudinal axis, wherein the tab head of the second torsion tab cooperates with the second sheet metal component such that the tab head clamps the second sheet metal component to the main metal sheet of the shaped component. Accordingly, two sheet metal components can be connected to one another in this way using the shaped component. In at least one configuration, two sheet metal components can be joined edge to edge by the shaped component. In some configurations the present disclosure provides that when providing at least two torsion tabs, the torsion tabs extend from the plane of the main metal sheet toward opposing sides of the main metal sheet so that two sheet metal components can be connected parallel to each other, wherein the shaped component is arranged between the sheet metal components. In some configurations the present disclosure provides that by using the shaped component, two sheet metal components can be connected together, in that at least one torsion tab is guided through a recess in a first sheet metal component and simultaneously through a recess in a second sheet metal component and then is twisted around the center longitudinal axis. In this manner, for example, overlapping connections of sheet metal components can be implemented by the shaped component.
In at least one configuration the present disclosure provides that a positioner of the shaped component is inserted into at least one positioning opening of a sheet metal component.

In some configurations the present disclosure provides that the shaped component is bent along a material attenuation, for example before the connecting of two sheet metal components. In at least one configuration the present disclosure provides that the shaped component is bent along a material attenuation, after the connecting of the two sheet metal components. In some configurations, a sheet metal component is used as a lever in order to bend the shaped component along the material attenuation.
In at least one configuration, the shaped component additionally or alternatively can be connected to the sheet metal components by a screw. In this regard a screw is inserted or screwed through the screw hole and the metal-sheet component and secured in place for example by using a nut. In some configurations, the present disclosure provides that a hex-head screw and/or a nut having an associated screw hole of the shaped component is held in a rotation-locked manner by a non-twisted torsion tab. The screw connection is established through the screw hole in such a manner that one flank of the nut or one flank of the head of the hex-head screw, respectively, essentially rests against, or at least partly rests against, the torsion tab. In at least one configuration the present disclosure provides that a free play is provided between the torsion tab and one flank of the hex-head screw or the nut, that additionally is structured such that the hex-head screw or the nut, respectively, can rotate by no more than about 0.5° up to about 10°, for example no more than by about 1° up to about 5°.
In some configurations, use of a screw connection which is associated with the screw hole, provides for the shaped component to be connected to a sheet metal component which does not have any recess for the torsion tab. Also a screw connection which is associated with the screw hole provides for the shaped component to be connected to a metal-sheet component which does not have any recess for the positioner. For example, a hole is drilled into the sheet metal component which can be aligned with the screw hole of the shaped component. This configuration is advantageous for using the shaped component with sheet metal components which are not adapted to the shaped component, or for example, shortened sheet metal components which do not have any recesses, or do not have suitable recesses for the torsion tabs.
In still yet another form of the present disclosure, a system of a sheet construction is provide and comprises at least one first sheet metal component and at least one shaped component as described above. At least one torsion tab of the shaped component extends at least through at least one first recess of a first sheet metal component, and is twisted by about 10° up to about 170°, by about 30° up to about 120°, by about 40° up to about 100°, or by about 45°, such that a tab head, for example a clamping region of a tab head, of the at least one torsion tab cooperates with the first sheet metal part such that the main metal sheet of the shaped component is clamped to the first sheet metal part.

In at least one configuration, the present disclosure provides that the recess of the first and/or of the second sheet metal component features a first extension which is greater than an extension of the tab head perpendicular to a center longitudinal axis of the torsion tab and perpendicular to the material thickness of the torsion tab. Furthermore, the recess additionally features a second extension which is greater than a material thickness of the torsion tab and is less than an extension of the tab head perpendicular to a center longitudinal axis of the torsion tab and perpendicular to the direction of the material thickness of the torsion tab, wherein the first extension is essentially perpendicular to the second extension. In this manner the torsion tab can be inserted through the recess and after the torsion of the torsion tab, it is seated in a positive locking manner in the recess around the center longitudinal axis, for example in a positive-locking manner in the direction of the center longitudinal axis.
In some configurations, the present disclosure provides that a material thickness of a sheet metal component is roughly as great as a length of a torsion region in the direction of a center longitudinal axis of the torsion tab. In at least one configuration, the present disclosure provides that a material thickness of a sheet metal component is greater than a length of a torsion region in the direction of a center longitudinal axis of the torsion tab. The torsion region, for example the torsion region in connection with the clamping region of the tab head, is designed such that by twisting of the tab head or by twisting of the torsion tab the clamping region of the tab head will act upon the sheet metal component. In this regard the present disclosure provides that the torsion region is shorter in the direction on the longitudinal axis of the tab head than the material thickness of the sheet metal component. In some configurations the torsion region in the direction of the longitudinal axis of the tab head is at least 20% shorter, at least 50% shorter, or at least 75% shorter than the material thickness of the sheet metal component. In at least one configuration the present disclosure provides that the torsion region has a length in the direction of the center longitudinal axis from up to about one-fourth of the material thickness of the sheet metal component, for example up to about 1.5 times the material thickness of the sheet metal component, up to about one times the material thickness of the sheet metal component, up to about three-quarters of the material thickness of the sheet metal component, or up to about one-half the material thickness of the sheet metal component. The clamping region is configured such that this region is essentially adapted to the opening width of the recess of the sheet metal component. For example, in at least one configuration the present disclosure provides that the torsion region, for example the torsion region in connection with the clamping region, has a length of about 50% up to about 95%, or about 75% up to about 80%, of the material thickness of the sheet metal component, and the clamping region is extended such that in a rotation of about 45° it acts on the sheet metal component such that a force of about 0.1 N up to about 5 N, or about 0.1 N up to about 2 N, is transferred from the clamping region to the sheet metal component.
The clamping of the shaped component with the sheet metal component can provide a reliable electrically conducting connection. Furthermore the clamping of the shaped component with the sheet metal component can provide that the at least one positioner is safely disposed in the at least one positioning opening of the sheet metal component, and any slippage of the positioner from the positioning opening is inhibited or prevented. In this manner a defined positive-locking of the shaped component with the sheet metal component is provided and/or assured. It should be understood that the positive-locking of the shaped component to the sheet metal component is more defined, due to the positioner, than a positive-locking provided solely by the torsion tab.

For example, the shaped component is connected to the sheet metal component as a single piece. In at least one configuration the present disclosure provides that the sheet metal component comprises at least one torsion tab.

At least one first torsion tab extends, for example, through the first recess of the first sheet metal component, and at least one second torsion tab extends, for example through the second recess of the second sheet metal component. The sheet metal components are joined together edge to edge. The torsion tabs are twisted about the particular longitudinal axis to obtain a positive-locking and frictional connection of the shaped component to the sheet metal components. The clamping regions of the torsion tabs act on the sheet metal components.
In some configurations, the present disclosure provides that at least one sheet metal component is a cable guide component, selected from a group comprising a cable guide, a cable channel, a cable trough and/or a cable trough covering.
In at least one configuration the shaped component is designed in such that it can connect two cable guide components together.
