Description

The present invention relates to a kit of construction profile, profile connector and different support arms.

Construction profiles and connectors are used for the production of simple work equipment, but also for the creation of more complex items such as machine tables, workshop equipment or for creating in their spatial form again and again changed constructed objects such as exhibition stands.

Construction profiles, connectors and support arms are also used for the production of objects in the field of organization, storage, hobby, for example for the construction of shelves, wardrobes, bases, ladders, trellises, dog crates or bicycle trailers. Here it is desirable to be able to attach as many different support arms to the construction profiles in order to allow a variety of constructions. The brackets serve as a shelf, coat hooks, towel rails, hinge brackets, mounting options for information boards and so on.

Construction profiles as construction elements are often used multiple times, especially in trade fair construction. They are connected with rigid or hinged connectors. Construction profiles are rod-shaped products whose cross-sectional geometry does not change or does not change significantly over their entire length. They usually have a surface profiling in the form of more or less undercut longitudinal grooves, wherein known construction profiles can also have a plurality of parallel longitudinal grooves per construction profile side. The undercut longitudinal grooves are used to receive sliding blocks of profile connectors, with other construction profiles are braced against these nuts, so that it comes to a frictional connection of the profiles. In general, the construction profiles have an outwardly closed internal cavity, which also extends in the longitudinal direction of the construction profile, usually concentric about its longitudinal axis, and which serves to receive in it or threaded objects. This cavity is also called a core hole. Such construction profiles are usually made of extruded aluminum. Such known construction profiles are for example in the DE 10 2004 043 964 A1 or the DE 93 13 596 U1 described.

These documents also describe profile connectors for two profiles oriented at right angles to each other. One of these connectors consists of two, arranged in the first construction profile groove stones, each having on its, the second construction profile side facing, provided with a threaded hole recess. They are oriented to each other so that these recesses are connected to a fixed to the second construction profile bar. The strip has four through holes, two of which are used for fastening by means of screws in the cavities of the second profile. The other two through holes are penetrated by screws, which each engage in a threaded bore of the sliding blocks and which are guided in each case a longitudinal groove of the first construction profile.

These known construction profiles and connectors have a number of disadvantages. The known connector, for example, complicated and cumbersome to assemble. A disadvantage of the known construction profile is that it can be difficult to connect with other than other construction profiles, which also only stand up easily on the first construction profile. In particular, support arms can be attached to these construction profiles usually only with their damage safely.

From the EP 0 118 411 A2 is a construction profile with connector known. The known construction profile has an internal cavity from which extend eight symmetrically distributed radially outward-facing and free-ending arms defining grooves between them. The arms further have ribs, with the opposing ribs of two arms lying on a common plane and a plurality of ribs defining multiple planes.

As documents of the prior art are further the DE 10 2007 030 925 A1 , the FR 2 545 163 A1 and the US 6,185,887 B1 known.

Object of the present invention is therefore to provide a kit of a construction profile, a profile connector and different support arms, which avoids these disadvantages. According to the invention, a multiplicity of different objects can be produced from this system, wherein these objects always have a defined and safe construction.

This object is achieved in the kit according to the invention by the features of claim 1. In the construction profile according to the invention, the groove slot is limited by two webs facing away from each other, which are stair-like designed such that in each case one step of a web with a step of the other web is on a plane, wherein at least two spaced apart stair steps are provided, whose planes are arranged parallel to each other. With great advantage, the construction profile according to the invention by the facing away from each other, lying on a plane stairs hereby a further, the groove channel useful complementary, bearing surface for attachment of objects. For the introduction of force is with great advantage a much larger area or thickness of material available, the support surface advantageously also prevents the rotation of the objects. Characterized in that the planes are arranged parallel to each other, different wide objects can be securely attached to the construction profile, so that different sized support arms can be used without the aid of exactly vertical alignment would be necessary. Characterized in that the steps are formed by the actual surface of the construction profile reset, lateral guidance of support arms, but above all a non-visible contact surface, so that no further damage to the construction profile remains when re-mounting or changing the support arm. The more stairs are provided, the more diverse the width of securely attachable objects can be selected.

In an embodiment of the construction profile according to the invention it is provided that the inner cavity is cylindrical and has an inner diameter which allows to receive a threaded rod, in particular an M8 threaded rod with sliding tolerance or to screw an M10 threaded rod. The cylindrical inner cavity, also called the core hole, is thus designed according to the invention so that a threaded rod can be received in it, whereby two construction profiles can be loosely or firmly connected in their longitudinal direction.

Is, as provided according to the invention in the construction profile, formed the web of an undercut longitudinal groove connected by a transition region with the web of another undercut longitudinal groove, and the transition region has a radius, the result is a profile without sharp edges visible from the outside, which the Reduces the risk of injury and especially in constructions with public contact, such as exhibition stands, is of particular advantage. At the same time, a rounded surface can be damaged much more severely than an edge, so that the construction profile according to the invention has an illustrative surface even when used repeatedly.

It is furthermore provided that the undercut longitudinal groove of the construction profile formed with steps is provided only on one side or on two adjacent or on two opposite or on three sides or on all sides of the construction profile. By virtue of this feature of n, n-1, n-2, etc. undercut longitudinal grooves per construction profile, with n = number of sides of the construction profile, two advantages can be achieved with advantage: on the one hand, an otherwise necessary covering of an unnecessary undercut longitudinal groove is dispensed with, On the other hand, there is a continuous surface on the side without undercut longitudinal groove, which is advantageous for example when mounting in corners or on walls, since the construction profile according to the invention then rests over its entire contact surface and thus secure fastened. Of course, the invention also covers such construction profiles, in which on each side at least one inventively designed undercut longitudinal groove is provided.

In an embodiment of the invention, it is provided that the first corresponding step pair of the construction profile has a width of 12.5 mm and the second has a width of 16.5 mm. This allows with great advantage the use of other profiles of the Applicant, which are precisely adapted to this unusual and non-standard measure, so that the construction profile of the invention can be connected to a variety of mounting hooks, sheets, tubes, etc., which in turn formed interconnected again could be. For example, a holding profile according to the DE 10 2007 030 925 A1 attachable, resulting in an additional possibility of attachment of the constructed of the inventive construction profiles object on ceilings, walls or floors.

If the construction profile according to the invention is designed as a triangular, quadrangular, pentagonal or regular polygon, then it can be adapted with particular advantage to many fields of use and enable the most varied geometries, for example honeycomb structures or pentagonal or triangular structures. This allows with advantage the most diverse constructions, for which no special angles or aids are necessary, but rather always the safe and protected from visible damage invention is used.

Are the wall of the inner cavity and the undercut longitudinal groove of the construction profile connected together, so there is a particularly stable construction profile.

Assign the undercut longitudinal grooves of the construction profile on its, the groove slot opposite sides of a groove slot centrally disposed V-groove, so can be done with great advantage, a mounting without great effort always centered, because the V-groove facilitates the positioning and guidance of a drill or the like.

The profile connector according to the invention has two mutually connected, mutually perpendicular sides and a side connecting the free ends of the two sides together, in which each side has an integrally molded profiled that designed to engage in the undercut longitudinal groove of the construction profile according to the invention and with sliding tolerance on the formed inner shape adapted, wherein the profile web has a staircase, which is formed in its step width and height corresponding to that of the construction profile according to the invention. The full-sided Anformung a profile web with Nutsteinquerschnitt causes in conjunction with the resting on the Treppierung the construction profile of the profile ridge a secure non-positive grip, at the same time an edge-free transition of the two profiles. Although disadvantageous in principle, such a profile connector according to the invention leads to a constructively safer and visually appealing connection of two construction profiles than known connectors. The disadvantage arises from the need to introduce profile connector according to the invention before the connection of the construction profiles in exact number in the groove channel, whereas it is possible in the known connectors, simply introduce any number of groove stones and only to use the required. That is, in known connectors a subsequent change of the originally provided construction is much easier than in the invention.

If the connecting side is designed with a radius, then there is a risk of injury-free transition, the loads moreover sufficiently more than sufficient.

According to the invention, the profiled web has on each side at least one recess in the part of the profiled web formed as a sliding block, or the connecting side has at least one passage bore corresponding to the recess. This results in a readily accessible from outside a construction profile according to the invention and yet stable clamping mechanism. This is formed by a provided in the through hole, or this penetrating screw and provided in the recess, against rotation trained mother, which is adjustable by means of the screw in position for the stepping of the profile connector and through which the clamping force is introduced into the construction profile ,

Does the profile web in the connection region of the two sides arranged at right angles to each other no groove profile, so two construction profiles can be connected to each other almost without spacing.

According to the invention, a support arm for attachment to a construction profile according to the invention to the invention, which has a molded profile web formed to engage in the undercut of the longitudinal groove of the construction profile according to the invention and formed with a sliding tolerance adapted to the inner shape, wherein the profile web has a staircase, the is formed in its step width and height corresponding to that of the construction profile according to the invention.
