Abstract

The profile connector (5) for the connecting of a profile (3a) to at least one other component (3b) has a tensioning element (18) by which clamping elements (17,19) are movable relative to one another along their slide faces, through which the two clamping surfaces of the clamping elements are displaceable relative to one another by an alignment component perpendicular to the clamping faces. The tensioning element acts upon an abutment (20) through which the component can be connected to the profile. An independent claim is included for a profile assembly with a profile and another component connected to the profile by the aforesaid connector.

Description

The The present invention relates to a profile connector for connection a profile with at least one other component. In particular The invention relates to a profile connector, which is by means of two by means of a clamping element displaceable clamping elements jammed on the profile, and by means of which the profile can be drawn towards the component. Further The invention relates to a profile arrangement with a profile and another, with the profile through the profile connector according to the invention connected component.

Specially trained profiles are often used for the construction of machine frames, work tables, cabinet frames and the like. Such a profile, which is only an example, is known under the name Bosch Rexroth aluminum strut profile. It is an elongated square strut with longitudinal grooves formed on the side surfaces of the strut. These struts can be provided in standardized sizes or simply cut to a desired size. In order to build a frame using the struts, for example, the struts must be connected to one another, preferably in a detachable manner. Two struts can either be connected at their end faces, thereby forming an elongated strut, or the struts can be connected to one another at an angle to one another, ie the end face of one strut adjoins the side face of the other strut. In the most common case, the struts are arranged at right angles to each other. A connector for such profiles is in DE 41 42 273 A1 shown.

In order to connect two struts together, hammer screws are commonly used. These are inserted in an end region of the first strut in their longitudinal groove and engage with their hammer-shaped head in a transverse groove formed in the strut, the transverse groove being introduced in the profile transversely to the longitudinal groove. At the other end, the hammer screw engages in a threaded slot nut. This engages behind the undercut longitudinal profile of the second profile. By tightening the screw, the two profiles can be moved towards each other and finally fixed against each other. From the DE 34 38 773 C2 an example of a profile connector formed in a similar manner is known.

In the US 4,641,983 Another profile connector is disclosed. A T-shaped end piece of an elongated connecting element engages behind the longitudinal groove of a first profile strut, the connecting element protruding transversely from the side surface of the profile strut. The connecting element is inserted from the end face into a longitudinal groove of a second profile strut to be connected to this first profile strut. A conical recess is machined into the side of the connecting element. In a region where the conical recess of the connecting element inserted into the longitudinal groove of the second strut is located, a likewise conical clamping screw is arranged laterally in a threaded opening in the second profile strut. The axes of the clamping screw and the recess are slightly offset in parallel. When the tensioning screw is screwed into the conical recess, which is complementary to it, the oblique lateral flanks of the tensioning screw and the recess come into contact. By further tightening the clamping screw, the connecting element is pulled axially away from the end face of the second strut, and in this way the two profile struts are fixed to one another.

Another profile connector is from the German utility model DE 200 15 795 U1 known. A head piece designed as a hammer head is welded or screwed to a connector main part. The head piece engages behind the longitudinal groove of a first profile strut. The main part is inserted longitudinally into the longitudinal groove of a second profile strut and fixed to the second profile strut by means of a pointed screw extending transversely through the main part. In this case, holes are made in an end region of the second profile strut near the end face, into which the conical tip of the screw can be moved, as a result of which the cone can move the main part together with the hammer head in the longitudinal direction and thus the first can be braced against the second profile.

through the one listed above Profile connectors can two profile struts arranged at right angles to each other drawn and fixed against each other. However, this must at least on one of the profile struts in an area near the front this profile strut further recesses are made. So must, for example, in the examples of profile arrangements described above either a transverse groove for milled the head of the hammer screw or the clamping screw receiving lateral thread opening be introduced. This means that before connecting two Profile struts at least on one of the struts machining steps carried out Need to become. In addition to the labor and cost involved, this leads to Removing material from a strut also turns into a mechanical one weakening the strut.

From the EP 0 653 568 A2 a connecting element is known by means of which two objects are clamped together that can. For this purpose, the two objects on their opposite sides must each have a T-shaped profile rail projecting away from these sides. The two rails are brought into contact with one another, and the connecting element engages around the two rails laterally. The connecting element consists of two wedge-shaped individual parts, a connecting screw running longitudinally through an oval recess in the first wedge-shaped part and engaging a thread in the second wedge-shaped part. The connecting screw runs parallel to the direction of extension of the profile rails. If the connecting screw is tightened, the two wedge-shaped parts, along the contact surface of the two parts, which run obliquely to the direction of extension of the profile rails, offset one another transversely to the direction of extension of the screw and thus clamp the two T-profiles against one another with their areas encompassing the T-profiles.

Also with this connector further precautions on the two parts to be connected be made. For example, must be connected to the T-profiles to be arranged on each side of the two parts be provided. For example, two elongated profile struts should be perpendicular to each other would have to be connected on the face the one profile strut after it has been sawn to the desired length, the T-profile welded on or fixed in any other way.

It is therefore an object of the present invention, a profile connector provide, by means of which one profile can easily be combined with another Component can be connected without further processing steps necessary on the profile are. In particular, there should be no machining steps to be necessary. A profile arrangement is also to be provided be in which a profile by means of a profile connector with a can be connected to the component without the profile Material processing steps must be carried out.

The profile connector according to the invention has two clamping elements, a clamping element and an abutment. The profile connector is designed to stand against each other opposing surfaces of the profile - below referred to as holding surfaces - jam to be able to. These individual components of the profile connector are described below explained become.

The two clamping elements each have a sliding surface and one of the sliding surface opposite clamping surface on. The two clamping elements are along a direction of displacement relocatable relative to each other. In accordance with the application, i.e. if the profile connector is arranged on the profile to this with the other component to connect, the direction of displacement is essentially parallel to at least one of the holding surfaces. If the holding surfaces for example as part of an undercut longitudinal groove Profile, the direction of displacement is essentially correct according to the application with the direction of extension of the longitudinal groove.

The Clamping elements are used in accordance with each with their sliding surfaces arranged adjacent to each other. In other words, they touch sliding surfaces of the two clamping elements according to use at least in some areas.

At least one of the clamping elements has a wedge area along one the direction of displacement varying thickness distance between the sliding surface and clamping surface on. Expressed differently, changed the thickness of the preferably elongated clamping element starting from a thickness at one end of the clamping element an opposite end of the Clamping element. In the simplest case, at least one of the clamping elements is than elongated Wedge executed, i.e. the sliding surface and the clamping surface this clamping element are each flat and close one Angle with each other. However, clamping elements are also conceivable which have an uneven sliding or clamping surface.

through the clamping element are the clamping elements along the sliding surfaces and especially along the direction of displacement relative to each other displaced. This means that the tensioning element at least one of the clamping elements can exert a force which causes this to move Clamping element opposite the other clamping element. Since the thickness is at least one of the clamping elements varies along the direction of displacement, introduces Relocating the clamping elements relative to each other so that the two clamping surfaces with a directional component perpendicular to the clamping surfaces relative shift to each other.

In other words, the tensioning element can exert a force parallel to a tensioning direction, which generally coincides with the main direction of extension of the tensioning element, on the clamping elements. This force generally does not act exactly along the sliding surfaces, but at an angle to the sliding surfaces. Since the clamping elements can only move against each other along the sliding surfaces, they are thus also offset in a direction transverse to the clamping direction. This offset corresponds to moving the two clamping surfaces away from each other. In this way, the two clamping surfaces jam against the holding surfaces of the profile, for example spread apart.

The Profile connector also has an abutment on which the Clamping element attacks and through which the further component can be drawn to the profile. The abutment can be part of the other component or be held on it. For example can the abutment as a nut, which is held on the other component is formed as an integral thread in the further component or also as part of another arranged in the further component profile connector according to the invention be trained.

The connector already mentioned DE 41 42 273 A1 already shows essential features of the above. However, the clamping elements of this connector each have a sliding surface, which enclose a relatively large angle of the order of 15 ° with the clamping surface of the respective clamping element, which leads to a relatively short sliding surface compared to the clamping surface. The head of the tensioning element, e.g. B. the clamping screw, is therefore arranged at a considerable distance from the sliding surface and as a result of this geometry between the contact of the head with the clamping element and the sliding surface spaced therefrom there are considerable moment forces which lead to an uneven force distribution along the clamping surface against the profile. In extreme cases, this can lead to damage to the profile, particularly in the case of "soft" profiles. In order to avoid such force peaks, in one embodiment DE 41 42 273 A1 a stop is provided, which prevents excessive sliding of the clamping elements relative to one another and is thus intended to prevent voltage peaks. At the same time, this stop also clearly limits the maximum holding force of the clamping element.

It is therefore an object of the present invention, a connector to provide, which does not require a stop to limit the force and thus allows the maximum clamping force of the profile connector.

According to the invention Task solved by that at least one of the clamping elements is formed with a sliding surface is that with the clamping surface the clamping element an angle of less than 10 ° and preferably between 1 °, 2 ° or 4 ° and 10 °.

By this significantly reduced angle compared to the state of the Technology becomes the sliding surface much longer, what the formation of tilting moments and thus of surface pressure peaks avoids. In addition, it is preferred to use the abutment for the tensioning element and in particular the head of the clamping screw essentially directly in Connection to the end of the sliding surface of the corresponding clamping element to be provided so that the distance between the sliding surface used and shortened this abutment is and therefore additional the formation of additional clamping forces is reduced is. Moreover let yourself in this way a very compact and relatively short clamping element compared to the transferable Establish holding force. With such a construction Clamping force above the clamping surface essentially constant so that a maximum holding force is transmitted can be.

Provided the sliding surface and the clamping surface both are flat, this angle is determined as the angle whose two levels. In the case of uneven sliding or clamping surfaces the angle as the average angle from in the direction of displacement the respective area created tangents.

This Angle between the sliding surface and the clamping surface represents a measure of the leverage ratio between the force exerted by the clamping element on the clamping elements and that of the clamping surfaces of the clamping elements on opposite holding surfaces of the profile exercised Force.

According to one embodiment are the clamping surfaces of the two clamping elements arranged substantially parallel to each other. This means that the thickness distance between the sliding surface and clamping surface with both clamping elements at least in areas where touch the clamping elements with their sliding surfaces, changes along the direction of displacement.

The Thickness variation of the clamping elements is complementary to each other. Expressed differently, is the sum of the thickness spacing of the first clamping element and the Thickness spacing of the second clamping element is constant if you look at different Measures points along the direction of displacement.

In the example of the simple, wedge-shaped configuration of the clamping elements, this means that both clamping elements have essentially the same angle between the clamping surface and the sliding surface and the wedges are arranged opposite one another. This also has the consequence that the clamping surfaces, when the clamping elements are displaced relative to one another along the sliding surface, are displaced transversely to one another and can thus press flat against the two, for example parallel, holding surfaces formed on the profile. In other words, displacement of the clamping elements along the direction of displacement also causes a displacement of the clamping surfaces in the direction of a surface normal of the respective clamping surfaces.

According to one embodiment the clamping element is elongated formed and essentially in a plane parallel to one the clamping surfaces provided. This means that the tensioning element has a main direction of extension which is arranged substantially parallel to at least one of the clamping surfaces is. In use, i.e. when the profile is connected to the other component to be, the clamping element is designed such that it further component essentially in the longitudinal direction of the clamping element clamps against the profile.

The Clamping element met thus two functions: It causes the clamping elements to be moved along the sliding surface, whereby these with their clamping surfaces against the two holding surfaces of the Can jam profiles. At the same time, the clamping element pulls the other component over the arranged on this abutment towards the profile.

According to one another embodiment is at least one of the clamping elements with a recess along the Displacement direction provided, the clamping element in the recess can extend. The recess can be completely outlined Be designed recess or in the form of a superficial Longitudinal recess the direction of displacement provided in the area of the sliding surface his.

It can also be provided that a recess in both clamping elements is formed and the clamping element along the direction of displacement first through the recess of one and then the other clamping element extends. The recesses are in this case along the Direction of displacement arranged one behind the other.

alternative could do that the recesses in the two clamping elements are also parallel complete, i.e. a recess in the first clamping element and a recess longitudinally in the second clamping element each the entire length of the Complement the clamping elements to an overall recess, through which the tensioning element extends can extend.

For example the clamping element can have a circular cross section, and in the sliding surfaces of the clamping elements can each provided substantially semicircular recesses his. Since the clamping elements are arranged adjacent to one another with their sliding surface are, the two semicircular recesses together a circular Recess through which the tensioning element can extend.

According to one embodiment of the present invention have the tensioning element and the abutment one screw thread each. The screw threads are included designed such that the clamping element cooperate with the abutment can. It can be both the clamping element with an external thread be provided, which can be screwed into an internal thread of the abutment is, as vice versa, the clamping element with an internal thread can be provided in which the external thread of an abutment is screwed in.

The Abutment can be a separate screw or nut, for example be designed as a hammer nut or sliding block. In this case can the abutment in an undercut longitudinal groove as a further component acting profile are inserted, together with the two clamping elements arranged in the first profile clamping element can be screwed into the abutment, whereby the two Have profiles braced against each other.

on the other hand the abutment can also be designed integrally with the other component, i.e. that in the other component a corresponding screw thread is arranged with which the clamping element can cooperate.

Around to enable the clamping element to be clamped without tools, can also be used as a quick release fastener (similar to a quick release hub a bicycle) can be provided, in which by means of a suitable designed lever the distance between the lever and the abutment changed by flipping the lever can be.

According to one another embodiment at least one of the clamping elements one out of its clamping surface outstanding lead. This means, the clamping surface is not completely flat, but has an or, for example several points, edges or ridges, which are in the holding surface of the Profiles against which the clamping element is pressed in accordance with the application can press into it.

While in the case of flat clamping surfaces only frictional forces between the clamping surfaces of the profile connector and the holding surfaces of the profile prevent the clamping elements from slipping, a projection protruding from the clamping surface can result in the corresponding clamping element interlocking with the surface against which it is pressed. In this way, a sliding of the clamping surface along the surface can be more effective be prevented.

Of Furthermore, the outstanding lead can cause that Clamping element pushes a little into the structure of the profile. Thereby For example, an electrical contact between the profile and the Profilver binder are manufactured or improved. This applies in particular in the case of aluminum profiles, the surface of which an electrically insulating aluminum oxide is covered. The lead the clamping surface can penetrate this alumina and make electrical contact to the aluminum underneath. In this way can about the profile connector an electrical connection between the profile and the other component can be reached. Using the example of a machine frame this can be important e.g. to ground the entire rack.

In one embodiment are the two clamping elements of a profile connector by means of a connecting means with the sliding surfaces connected adjacent. This can be achieved, for example be that between the sliding surfaces of the two clamping elements there is an adhesive layer which detachably connects the two sliding surfaces to one another combines. In another embodiment, the two clamping elements for example, be spanned by a rubber or an adhesive tape. The connecting means prevents the profile connector disassembles into its individual parts before assembly on the profile. The Profile connector is thus easier to handle, since it as a unit handled and brought to its destination in the profile can. Only when the two clamping elements through the clamping element are moved against each other, that is released by the connecting means effected connection of the two clamping elements, and the sliding surfaces can freely be moved against each other.

According to one Another aspect of the present invention is a profile arrangement provided with a profile and another component, wherein the profile through a profile connector, as described above was connected to the other component. The profile points a first surface and one of the first surface across from lying, second surface on. Against these two surfaces of the profile - before already as holding areas designated - jam the two opposite clamping surfaces of the clamping elements of the Profile connector, which is relative to each other by means of the clamping element are relocatable. The abutment of the clamping element is on the other component provided.

The two holding surfaces are preferably arranged parallel to one another, but can also make an angle to each other that is preferably small is enough to have a good power transmission the clamping elements normal to the holding surfaces to ensure this. Between the two holding surfaces there is a room in which the profile connectors are arranged can. The holding surfaces have to also not be plan, but can also have, for example, a semicircular contour, the clamping surfaces of the Clamping elements preferably have a complementary geometry to yourself if possible flat against the two holding surfaces to be able to press.

The Width of the profile connector when not installed, i.e. the Distance between the two clamping surfaces of the profile connector, should preferably be minor be less than the distance between the two holding surfaces. at The assembly of the profile connector will be the two clamping elements now shifted against each other, and their clamping surfaces offset in this way to the outside, whereby the profile connector against the two holding surfaces of the Profile spread.

In one embodiment The profile arrangement includes both the profile and the other component each as an elongated Profiles formed with an undercut longitudinal groove, the first and second holding surfaces of the profile through surfaces the undercut longitudinal groove are formed. Here, under an undercut longitudinal groove, there is a groove understood that a smaller on the side surface of the profile Has width than in a further within the profile Area. The width should be such that the clamping element of the profile connector due to the narrowed area near the surface can reach through and into a nut arranged behind it in the groove, for example, a hammer nut or a sliding block can. This nut has a width that allows the mother to in the wider area of the undercut longitudinal groove from the front of the Profiles to be inserted here, which however prevents the nut slide out through the narrowed area of the undercut longitudinal groove can. The mother can thus as well as the clamping element attached to it Profile connector can be freely moved along the longitudinal groove, however, cannot be pulled out of the longitudinal groove transversely to the surface of the profile become.

It it should be noted that the clamping surfaces of the clamping elements in this way can be arranged that they are either against one another, facing each other surfaces the undercut longitudinal groove or against the floor surface and the opposite of this lying, through the transition from the widened to the narrower part of the undercut longitudinal groove jam formed surface can.

In one embodiment The profile arrangement includes both the profile and the other component again as elongated Profile formed with an undercut longitudinal groove, wherein in in this case the abutment as a further profile connector according to the invention is formed, which in the longitudinal groove of the second profile is jammed. In other words, it is both in the first as well as in the second profile a profile connector within the respective longitudinal groove, wherein both profile connectors spread against the holding surfaces of the respective longitudinal groove can be. Extends between the clamping elements of the two profile connectors either a single clamping element, which simultaneously the two clamping elements of both pairs of clamping elements against each other moves and thus jammed in the respective profile. However, it can also two in terms of effectiveness separate clamping elements for the two profile connectors can be provided, which via a additional Connecting element are interconnected.

The mentioned embodiment is particularly advantageous in the case in which the longitudinal directions of the two elongated profiles to be connected to one another is not perpendicular stand on each other, so that a pull on the abutment through the Clamping element for moving the abutment along the Profile groove of the second longitudinal profile to lead can. This shifting cannot occur if the abutment even as itself in the longitudinal groove jamming profile connector is formed.

According to one embodiment the profile arrangement, it is preferred that the longitudinal directions of the the first and the second profile are at an angle to one another, especially that the two elongated Profiles are arranged at right angles to each other.

After all, should in one embodiment of the Profile arrangement, the clamping elements and the other component in such a way be designed so that one of the clamping elements while it moved relative to the other clamping element by the clamping element is supported on the second profile. The clamping element can thereby open one of the clamping elements the other to be moved, the other clamping element, thereby that it is supported on the second profile, is not moved and thus the first clamping element with its sliding surface over the sliding surface of the second clamping element.

For example can be a support a clamping element on the as a profile with an undercut longitudinal groove trained, further component can be achieved in that the Clamping element a larger width than the narrowed part of the undercut longitudinal groove. This can the clamping element when moving from the clamping element to the second Profile is pushed, support on the side surface of the second profile.

The support one clamping element against the other component need not necessarily achieved by direct contact of the clamping element to the component become. The one necessary for support Strength can also be over intermediate elements, such as spacers or washers, transferred become.

The Invention will now be explained in more detail with reference to embodiments. Same or features with the same effect are each given the same reference numerals designated.

In the 1 . 2 and 3 is an embodiment of a profile arrangement according to the invention presented in different perspective cross-sectional views. For easier identification of the different perspectives and for unambiguous identification of different directions, corresponding coordinate systems were given in the three figures.

The profile arrangement 1 includes a first profile 3a and a second profile 3b , The two profiles 3a . 3b are through a profile connector 5 held together. In the following, the reference symbols with the additional abbreviation "a" refer to the first profile 3a features to be assigned, "b" denotes the second profile 3b assignable characteristics.

The two profiles 3a . 3b are designed as square profile struts. The profile struts are each mirror-symmetrical about the respective planes of symmetry S1a, S2a, S1b, S2b and are usually only shown in the figures for reasons of space up to the corresponding plane of symmetry. Several identical features of a profile occurring at different symmetry positions are identified by the same reference symbols.

Both the first profile strut 3a as well as the second profile strut 3b has undercut longitudinal grooves on each of its four sides 7a . 7b on. The longitudinal grooves 7a . 7b have a T-shaped cross section, ie a width of the longitudinal groove 7a . 7b in a plane parallel to the corresponding side surface of the profile strut is in a constriction area 9a . 9b less near the side surface of the profile strut than in a deeper expansion area 11a . 11b , Due to the T-shaped design of the longitudinal groove 7a . 7b has each of these longitudinal grooves 7a . 7b an upper surface 13a . 13b and a lower surface opposite this 15a . 15b on.

In a longitudinal groove 7a the first profile strut 3a is the profile connector 5 arranged. The profile connector 5 includes an upper clamping element 17 and a lower clamping element 19 as well as an elongated clamping screw 18 trained clamping element, the clamping screw 18 in a as a hammer nut 20 trained abutment engages.

On the basis of each of the 4A . 4B and 5A . 5B Cross-sectional views shown should now be the upper and lower clamping element 17 . 19 be described in more detail. The upper clamping element 17 has a clamping surface 21 and an opposite sliding surface 23 on. The clamping surface 21 is uneven, ie it has protrusions 25 on, whereas the sliding surface 23 is just trained. One level of the clamping surface 21 , out of which the ledges 25 extend, and a plane of the sliding surface 23 enclose an angle of approximately 6 °. In other words, the sliding surface runs 23 at an angle to the clamping surface 21 ,

In the sliding surface 23 is a recess 27 incorporated. The recess 27 has a width and a semicircular contour that that of the clamping screw 18 corresponds and extends in the longitudinal direction through the upper clamping element 17 ,

Even the lower clamping element 19 has a clamping surface 29 and a sliding surface 31 on. These two areas 29 . 31 are each flat and also form an angle of about 6 °. In the sliding surface 31 of the lower clamping element 19 is also a part-circular recess 33 incorporated.

The recesses 27 . 33 in the sliding surfaces 23 . 31 of the two clamping elements 17 . 19 extend in the longitudinal direction of the clamping elements 17 . 19 , ie they extend when the clamping elements in the undercut longitudinal groove 7a of the profile 3a are inserted in the longitudinal direction of the longitudinal groove 7a ,

The two clamping elements are used 17 . 19 with their sliding surfaces 23 . 21 arranged adjacent to each other. In that the sliding surface 23 and the clamping surface 21 of the upper clamping element 17 include the same angle as those 31 . 29 of the lower clamping element 19 , causes the clamping surfaces 21 . 29 when the two clamping elements 17 . 19 with their sliding surfaces 23 . 31 face each other, are arranged parallel to each other. Even if the clamping elements 17 . 19 along its longitudinal direction (in 1 For example, the Y direction) are shifted against each other, the two clamping surfaces remain 21 . 29 parallel to each other, but their distance from each other changes.

According to use extends through the recesses 27 . 33 of the two clamping elements 17 . 19 the clamping screw 18 , The dimensions of the recesses 27 . 33 the dimensions of the clamping screw 18 customized.

The tension screw 18 is at one end with a screw head 35 provided, which in the in 1 shown embodiment is designed as a hexagon socket screw head. The screw 18 is longer than the longitudinal extent of the two clamping elements 17 . 19 and engages with an external thread 37 into an internal thread (not shown represents) the hammer nut 20 on.

The hammer nut 20 is designed such that it is in the longitudinal groove 7b of the second profile 3b inserted and freely along this longitudinal groove 7b , (ie in 1 in the X direction). The hammer nut 20 has such a geometry that it is in the longitudinal groove 7b against their top surface 15b can support, ie it is wider than the constriction area 9b this longitudinal groove 7b ,

The following is a possible assembly and the mode of operation of the profile connector designed according to the invention 5 the one in the 1 to 3 shown profile arrangement 1 described.

The initial state is the two individual profiles 3a and 3b as well as a pre-assembled profile connector 5 , The pre-assembled profile connector 5 includes the two clamping elements 17 . 19 , the tension screw 18 and the hammer nut 20 , The two clamping elements are in the pre-assembled state 17 . 19 with each other with opposing sliding surfaces 23 . 31 connected. This connection can be made, for example, by a between the sliding surfaces 23 . 31 applied adhesive layer can be effected. The two clamping elements 17 . 19 are only so far overlapping that the distance between the clamping surface 21 of the first clamping element 17 and the clamping surface 29 of the second clamping element 19 is less than the distance between the top surface 13a and the bottom surface 15a the undercut longitudinal groove 7a of the first profile 3a , In the pre-assembled state, the clamping screw extends 18 through the recesses 27 . 33 in the sliding surfaces 23 . 31 of the two clamping elements 17 . 19 , On the thread 37 the clamping screw 18 is the hammer nut 20 slightly screwed on.

In this pre-assembled state, the profile connector 5 on the second profile 3b arranged by the hammer nut 20 from one end 39b of the profile 3b forth in the undercut longitudinal groove 7b is introduced. So is the hammer nut 20 in the undercut longitudinal groove 7b held such that they are along the longitudinal groove 7b can be moved, but not transversely to the longitudinal groove 7b (ie in 1 in the Y direction) from the longitudinal groove 7b can move out. The profile connector 5 is perpendicular to the side surface in this configuration 41b of the profile 3b off and can be in a position along the longitudinal groove 7b be pushed in the first profile 3a with its face 3a on the second profile 3b to be attached.

Next is the second profile 3b protruding part of the profile connector 5 from the front 39a forth in the longitudinal groove 7a of the first connector 3a introduced. The two profiles 3a . 3b are moved towards each other until the front side 39a of the first profile 3a adjacent to the side surface 41b of the second profile 3b located.

Next is the turnbuckle 18 tightened by means of a suitable key, namely in the present embodiment a hexagon Allen key, ie with its thread 37 into the corresponding thread of the hammer nut 20 screwed. Once the turnbuckle 18 doing it with her screw head 35 with a side surface of the upper clamping element 17 comes into contact, causes the clamping screw to be tightened further 18 that the upper clamping element 17 together with the lower clamping element connected to it via the adhesive layer 19 towards the second profile 3b is moved to. As soon as the lower clamping element 19 attached to the second profile 3b comes, ie on its side surface 41b supports, the clamping element 19 do not move further in this direction. to let. Supporting the lower clamping element 19 on the second profile 3b can be achieved in that the lower clamping element 19 has a width (in the Z direction) which is greater than the width of the undercut longitudinal groove 7b of the profile 3b in their narrowing area 9a ,

Because the lower clamping element 19 can no longer be moved, the tensioning screw is tightened further 18 that the provisional connection caused by the adhesive layer between the two clamping elements 17 . 19 solved, ie the adhesive layer between the two clamping elements is broken, and the upper clamping element 17 then along the sliding surfaces 23 via the second clamping element 19 pushes. Due to the slanted sliding surfaces 23 . 31 of the clamping elements 17 . 19 the distance between the clamping surfaces 21 . 29 of the two clamping elements 17 . 19 increased. In this way, the clamping elements 17 . 19 by tightening the clamping screw 18 against the upper and lower surface 15a . 13a the longitudinal groove 7a of the profile 3a braced. The increasing friction between the clamping surfaces 21 . 29 and the surfaces 13a . 15a of the profile 3a causes the profile connector 5 within the longitudinal groove 7a is fixed.

The angle between the clamping surfaces 21 . 29 and the sliding surfaces 23 . 31 is preferably chosen such that the expansion of the clamping elements 17 . 19 in the longitudinal groove 7a is self-locking. This means that the static friction between the two sliding surfaces 23 . 31 of the clamping elements 17 . 19 in its expanded state is sufficiently high to withstand the loosening clamping screw 18 a slipping apart and thus a despreading of the clamping elements 17 . 19 to prevent.

Tightening the clamping screw 18 also causes pulling in the in the longitudinal groove 7b of the second profile 3b held hammer nut 20 , The second profile 3b thus becomes the face 39a of the first profile 3a attracted.

Tightening the tension screw 18 therefore has two effects: On the one hand, the clamping elements 17 . 19 moves against each other and can thus move within the longitudinal groove 7a of the first profile 3a spread. On the other hand, the second profile becomes the same 3b about the hammer nut arranged in it 20 with its side surface 41b towards the front 39a of the first profile 3a pulled and fixed against it.

As an additional effect, they press on the clamping surface 21 arranged extensions 25 when spreading the two clamping elements 17 . 19 into the top surface 13a the longitudinal groove 7a of the first profile 3a , This increases the friction between the clamping element 17 and the surface 13a , At the same time, in the case of an aluminum profile, a superficial aluminum oxide layer can pass through the extensions 25 are penetrated, whereby a possibly desired electrical contact between the profile connector 5 and the first profile 3a can be manufactured. In an alternative embodiment, the hammer nut can also 20 be equipped with similar extensions (not shown) so that these extensions fit into the corresponding surface 15b the longitudinal groove 7b of the second profile 3b press and make an electrical contact there. In this way, the profile connector 5 an electrical connection between the first profile 3a and the second profile 3b be guaranteed.

6 shows an embodiment of a profile arrangement, which is similar to that in 1 embodiment shown. However, the two profiles are in this case 3a . 3b not perpendicular to each other. This has the consequence that as an abutment for the clamping screw 18 a special mother 20 ' must be used whose tapped hole is at the same angle to one on the top surface 15b the longitudinal groove 7b adjacent face 43b mother 20 ' has, like the angle between the side surface 41b of the second profile 3b and the longitudinal direction of the first profile 3a , In a mother trained in this way 20 ' can the clamping screw 18 of the profile connector 5 intervene and the second profile 3b with its side surface 41b towards the face 39a of the first profile 3a pull.

In 7 is a further embodiment of a profile arrangement according to the invention 1 shown in the two with profile grooves 7a . 7b provided profiles 3a . 3b along their end faces 39a . 39b are connected. In the embodiment shown, the two profiles close 3a . 3b an obtuse angle. This embodiment described below can, however, also be used in the case of profiles which are aligned with one another and are to be connected at the end.

In the two on the face of the two profiles 3a . 3b adjacent profile grooves 7a . 7b is a profile connector designed according to the invention 5a . 5b arranged. The two profile connectors 5a . 5b each have an upper clamping element 17a . 17b , a lower clamping element 19a . 19b and a common angled turnbuckle 18 ' ,

The tension screw 18 ' has two legs, the angle of which is the angle between the two profiles to be connected to one another 3a . 3b essentially corresponds. The tension screw points on both of its legs 18 ' one thread each. The two legs each run through recesses 27 . 33 in the clamping elements 17a . 17b . 19a . 19b , At their two opposite ends are on the turnbuckle 18 ' nuts each 61a . 61b screwed.

The clamping elements 17a . 19a . 17b . 19b jam against the longitudinal grooves 7a . 7b of profiles 3a . 3b , which is when tightening the nuts 61a . 61b developing clamping force and the resulting static friction between the lower clamping elements 19a . 19b and the corresponding walls of the longitudinal grooves 7a . 7b can prevent the respective lower clamping elements 19a . 19b along the longitudinal grooves 7a . 7b move.

According to a further embodiment, the lower clamping element 19a . 19b a ledge (similar to the ledges 25 ) at an end of the clamping element that is close to the opposite profile 19a . 19b be arranged, which is in the profile groove when jamming the clamping elements 7a . 7b jammed and thereby slipping of the profile connector 5 prevented.

Alternatively, between the two lower clamping elements 19a . 19b a correspondingly angled spacer element (not shown) can be provided, which prevents these clamping elements from slipping 19a . 19b to prevent each other.

In a further alternative, the two lower clamping elements move 19a . 19b when tightening the nuts 61a . 61b until they are in the area of the end faces 39a . 39b of profiles 3a . 3b come into contact with each other, thereby further slipping can be prevented.

In the in 7 shown embodiment acts in each case a pair of clamping elements 17a . 19a . 17b . 19b together with the common clamping screw running through it 18 ' and the mother screwed onto it 61a . 61b as an abutment for the one in the other profile 3a . 3b arranged profile connector part.

8th shows a further embodiment of a profile arrangement according to the invention 1 , In this case, a first profile 3a on another component 53 fixed.
