Description

Technical field

[0001] The present disclosure relates to a mounting device for mounting a cover profile on a profile bar according to claim 1 and a method for mounting a cover profile on a profile bar according to claim 10.

[0002] The applicant's catalog "Mechanical Basic Elements 14.0" with material number 3 842 540 391 (2019-07) discloses in chapter "2-2" strut profiles or profile bars extending with a rectangular cross-section. At least one of the rectangular sides has a groove with an undercut. The groove is designed to accommodate fasteners in variable positions on the profile bar. These fasteners allow the profile bars to be connected to form trusses, and external assemblies or attachments can be mounted to them. The profile bars, available in standardized widths, can be used for a wide range of applications, such as machine bases, linear guide frames, linear transfer systems, and the like.

[0003] The same catalog, chapter "2-84 (page 100) Cover profiles," details the groove covers. These have standardized widths and shapes that are matched to the grooves of the standardized profile bars. The cover profiles serve, for example, to protect the groove from dirt or to cover and protect cables routed in the groove.

[0004] Installing the cover profile in the groove proves to be a complex process. First, an end section of the cover profile must be inserted at a suitable point in the groove so that corresponding connecting sections of the cover profile engage behind the undercut. Then, the cover profile must be pressed in bit by bit along the desired length. This can lead to the cover profile becoming jammed or damaged, or it may be inserted incompletely in sections and not sit flush. If unnoticed, this can cause a malfunction.

[0005] In contrast, the invention aims to provide an assembly device that simplifies assembly and thus makes it more reliable. A further objective is to provide an assembly method that simplifies assembly and thus makes it more reliable.

[0006] The first problem is solved by an assembly device with the features of claim 1, the second problem is solved by a method with the features of claim 10. Preferred embodiments of the inventions are described in the respective dependent claims.

[0007] A mounting device according to the disclosure is designed and configured for mounting a cover profile onto a profile bar. The profile bar, onto which the cover profile can be mounted by means of the mounting device, has a rectangular outer cross-section with four rectangular sides. Along the profile bar, at least one groove, in particular an undercut and / or T-shaped groove, extends on at least one of its rectangular sides and is provided for receiving the cover profile. According to the disclosure, the mounting device has a base body on which at least two rollers are rotatably mounted with respect to their respective associated axes of rotation. Each roller has a cylindrical outer shape, in particular a cylindrical shape, with respect to its axis of rotation. Each roller is associated with an axle body, which is attached to the base body at one end section.With its opposite end section, the axle body projects into the associated roller to form the rotary bearing for the roller. The axes of rotation are aligned parallel, with the rollers arranged on the same side of the base body in the direction of the axes of rotation and positioned in pairs opposite each other in a direction transverse to the axes of rotation. To enable and / or simplify handling of the assembly device, the base body has a handle on the side facing away from the rollers, in particular with a knurled or ridged surface that facilitates a secure grip.

[0008] This creates an assembly direction that allows the mounting of the cover profile on the profile bar to proceed as disclosed: - Providing the assembly device, - Inserting a section of the cover profile into the groove, - Attaching the mounting device to the profile bar so that the profile bar is arranged between pairs of opposing rollers, with one selected roller being located in the area of ​​the already inserted section of the cover profile, and - Moving the mounting device along the profile bar so that the selected roller presses the cover profile into the assigned groove, in particular inserting it.

[0009] This allows the cover profile to be mounted along the profile bar by simply sliding the disclosed mounting device along the profile bar. Compared to a conventional mounting device based on sequentially pressing the cover profile in sections, the disclosed mounting device thus provides a simplified and more reliable assembly process.

[0010] According to a preferred embodiment, the base body is designed as a flat plate of constant thickness, with the axes of rotation oriented perpendicular to the plate. The plate thus designed can be easily brought into contact with one of the rectangular sides with good tactile feedback, which simplifies the positioning and movement of the mounting device.

[0011] According to a further development, the assembly device has a third roller, or rather three rollers, and the axes of rotation of the three rollers are arranged at the vertices of an imaginary triangle with two sides, in particular sides that are perpendicular to each other. In other words, the three axes of rotation form a triangle, in particular a right-angled one.

[0012] This results in several, in particular three, possible arrangements of the mounting device on the profile bar. One in which the profile bar intersects only one of the imaginary legs of the triangle. Another in which the profile bar intersects only the other imaginary leg of the triangle. A third in which the profile bar intersects both imaginary legs of the triangle.

[0013] According to a further development, the assembly device has a fourth roller, or rather four rollers, and the axes of rotation of the four rollers are arranged at the corners of an imaginary quadrilateral with at least two mutually perpendicular sides. In other words, the axes of rotation form a quadrilateral that has at least one right angle.

[0014] The fourth roller allows the mounting device to be used diagonally. In other words, the fourth roller provides the mounting device with several clear distances, measured between two rollers on one side and an opposing roller on the other.

[0015] According to further training, the sides that are at right angles to each other are of different lengths.

[0016] Preferably, the lengths of the rectangular sides are matched to the respective width of different profile bars or to the differently wide rectangular sides of the profile bar.

[0017] Preferably, the clear distances between the rollers resulting from the lengths and diameters of the rollers are adapted to a respective width of different profile bars or to differently wide rectangular sides of the profile bar.

[0018] In cases where the clear distances between the right-angled sides differ, cover profiles can be mounted on at least two profile bars of different widths or on two differently sized sides of the same profile bar using a single mounting device. In these cases, the profile bar must be positioned parallel to one of the right-angled sides.

[0019] Additionally, a profile bar with a third width can be attached by placing it parallel to a diagonal of the quadrilateral and intersecting the right-angled sides.

[0020] In a particularly preferred embodiment of the assembly device, four axes of rotation with four rollers are provided. Three of the axes of rotation form an imaginary right-angled triangle, the first leg of which has a first length and the second leg of which has a second length. The fourth axis of rotation is arranged beyond the hypotenuse of the imaginary right-angled triangle, and its height above the hypotenuse has a third length.

[0021] Preferably, the three clear distances, or the first, second and third clear distances, are chosen such that the first clear distance corresponds to a first width of the profile bar, the second clear distance to a second width of the profile bar or another profile bar, and the third clear distance to a third width of the profile bar or another profile bar.

[0022] The different widths are particularly preferred - or rather the first, second and third widths - 60mm, 45mm and 30mm.

[0023] To facilitate movement, according to a further development, the rollers are either plainly or roller-bearing mounted on the associated axle body. The plain bearing is preferred due to the simpler design requirements.

[0024] Preferably, the axle bodies are screwed to the base body; the same preferably applies to the handle. Alternatively, other joining methods or fasteners such as riveting, welding, and the like are of course possible. Alternatively, the base body can be manufactured in one piece, for example by injection molding or additive manufacturing.

[0025] In a preferred embodiment, the clear distance between opposing rollers is greater, in particular minimally greater, than the width of the profile bar or the side length of the rectangular outer cross-section of the profile bar, in particular of the largest profile bar provided, so that there is clearance which simplifies the attachment of the mounting device.

[0026] According to a preferred further development, the clearance is 0.1mm to 0.5mm, particularly preferably 0.2mm to 0.4mm, most particularly preferably 0.3mm.

[0027] Within this game, it is possible to attach and move the mounting device like a two-pronged fork on the profile.

[0028] A method according to the disclosure serves to mount a cover profile onto a profile bar having a rectangular outer cross-section with four rectangular sides. At least one groove, in particular an undercut and / or T-shaped groove, extends along the profile bar on at least one of its rectangular sides to receive the cover profile. According to the disclosure, the method comprises the following steps, which are preferably carried out in the specified order: - Providing an assembly device that is designed according to at least one aspect of the preceding description; - Inserting a section of the cover profile into the groove; - Attaching the mounting device to the profile bar so that the profile bar is arranged between opposing rollers, with one selected roller being located in the area of ​​the already inserted section of the cover profile; and - Moving the mounting device along the profile bar so that the selected roller presses or inserts the cover profile into the assigned groove.

[0029] To increase the indentation force, especially when the clearance between the profile bar and the opposing rollers is greater than defined above, the procedure may optionally include a step: - Rotating the mounting device or applying a torque to the mounting device during movement, so that the selected roller presses against the already inserted section of the cover profile and the section yet to be inserted; wherein the torque resulting from the rotation is supported by the roller located on the opposite side of the profile bar.

[0030] The twisting action makes it possible, in particular, to attach a mounting device designed for a larger profile bar to a smaller profile bar and to mount the cover profile.
