Description

The invention relates to a connection arrangement for the positive and non-positive connection of a first carrier profile which is elongated along a longitudinal direction and which, viewed in a transverse direction perpendicular to the longitudinal direction, has opposite side wall regions and a transverse wall region connecting these, which enclose an inner cavity, and a second carrier profile which is elongated along the longitudinal direction and has an end section which is inserted into the cavity in a form-fitting manner in the longitudinal direction and which has opposite side wall regions in the transverse direction, wherein a first contact surface is formed within the first carrier profile in the region of the cavity and a second contact surface is formed on the second carrier profile, wherein the contact surfaces are opposite one another and abut one another when viewed in a clamping direction perpendicular to the longitudinal and transverse directions.

Such a connection arrangement can be used on its own or can be expanded to include other components, in particular to form racks, frames, shelves, tables or other support arrangements. Screws or bolts are usually used to connect the two support profiles.

The object of the invention is to improve such a connecting arrangement so that it can be assembled and disassembled again only by hand, without tools.

To achieve this object, the invention provides that a first opening is formed in each side wall region of the first carrier profile, which has an inner surface extending along an inner circumference of the opening, wherein the first openings are arranged opposite one another in the transverse direction and a part of each inner surface which is remote from the first contact surface as viewed in the clamping direction forms a first clamping surface, wherein a second opening is formed in each side wall region of the second carrier profile, which has an inner surface extending along an inner circumference of the opening, wherein the second openings are arranged opposite one another in the transverse direction and a part of each inner surface which is closest to the second contact surface as viewed in the clamping direction forms a second clamping surface, wherein a clamping element is inserted into the first and second openings, which has first and second fastening surfaces on an outer circumference and is provided with a hand lever for manual actuation, wherein in a release position of the clamping element the contact surfaces are not pressed against one another, wherein the clamping element is rotated about a rotation axis running in the transverse direction in a clamping position can be brought in which the first fastening surface is in contact with the first clamping surface and the second fastening surface is in contact with the second clamping surface and the first contact surface is pressed against the second contact surface with a clamping force to form a positive and non-positive connection of the support profiles.

In the release position of the clamping element, the first fastening surface can be at a distance from the first clamping surface and/or the second fastening surface can be at a distance from the second clamping surface and/or the first contact surface can be at a distance from the second fastening surface when viewed in the clamping direction. Alternatively, all or some of the surfaces mentioned can rest loosely against one another without a clamping force being exerted.

In the clamping position, a force flow of the clamping force runs from the first clamping surface of the first carrier profile to the first fastening surface of the clamping element adjacent thereto, through the clamping element to its second fastening surface and to the second clamping surface of the second carrier profile adjacent thereto, through the second carrier profile to its second contact surface, to the first contact surface of the first carrier profile adjacent thereto, and through this again to its first clamping surface, so that the force flow has a closed course.

In the clamping position, the second fastening surface of the clamping element is in contact with the second support element in the region of a second clamping surface of the second support element. Depending on the cross-sectional shape of the second longitudinal support, this second clamping surface can be a uniform surface or different surfaces, whereby two clamping surfaces together can form the second clamping surface. If the second longitudinal support, for example, has a U-shaped cross section, the clamping element can, depending on the orientation of the cross section, either rest against free ends of the side walls of the longitudinal support that form the side wall regions and together form the second clamping surface, or from the outside against a base wall that transversely connects the side walls and forms the transverse wall region, which then forms the second clamping surface. In these cases, the base wall or the side walls of the second longitudinal support are pressed against the first longitudinal support in the assembled or clamped state.

If the first longitudinal beam has a U-shaped or rectangular cross-section, an inner side of its bottom wall can form the first contact surface. If the second longitudinal beam has a U-shaped or rectangular cross-section, an outer side of its bottom wall can form the second contact surface if the orientation of the U-shape is the same for both beam profiles. If the longitudinal beams with their U-shapes are oriented in opposite directions, an outer or underside of the side walls of the second beam profile can form the second contact surface.

It can be provided that the first and/or the second carrier profile has a top wall region opposite the transverse wall region, so that the first carrier profile has a cross-sectional shape that runs closed over a circumference and can be, for example, rectangular or round in cross-section, while the second carrier profile can be, for example, U-shaped, rectangular, round or H-shaped in cross-section. In such a case, the second clamping surface can be formed, for example, by a region of the top wall, provided that this can be distinguished from the base wall. In a design with two U-shaped carrier profiles, the open side of the second carrier profile can lie in the region of the open side of the first carrier profile or in the region of its transverse wall region or base wall. With a round cross-sectional shape of the carrier profiles, sections of the wall clearly form the side wall regions and sections connecting these form the transverse wall region, whereby side and transverse wall regions can partially merge into one another.

The first fastening surface can extend continuously across a width of the first carrier profile, from a first opening to the opposite first opening, in the transverse direction. Alternatively, it can be provided that a first fastening surface is formed at each end of the clamping element, in each case in a region of a first opening in the first carrier profile, which together form the first fastening surface.

In one variant, it can be provided that the second clamping surface or the second clamping surfaces is or are formed in a base region of a clamping slot of the second carrier profile running in the clamping direction. This forms an arrangement in which the clamping element is to be inserted transversely to the longitudinal direction into the clamping slot of the second carrier profile.

In a further variant, it can be provided that in the clamping position of the clamping element, the second fastening surface is in contact with an outer side of a bottom wall of the second carrier profile facing away from the transverse wall region of the first carrier profile.

In one embodiment, it can be provided that the second carrier element has two side wall regions opposite one another, wherein in each side wall region of the second carrier profile a second opening is arranged which has an inner surface extending over an inner circumference, wherein the second openings are arranged opposite one another in the transverse direction and a region of the inner surface facing the transverse wall region of the first carrier profile, viewed in the clamping direction, each forms a second clamping surface, wherein a first and second opening arranged immediately adjacent to one another are positioned such that they partially overlap when viewed in the transverse direction, wherein the clamping element extends through all the openings and in the clamping position the second fastening surface of the clamping element is in contact with the second clamping surface.

In another embodiment, it can be provided that the first openings in the region of the first clamping surfaces are formed in the manner of an undercut and each have an opening, so that the clamping element can be inserted through the openings transversely to the longitudinal direction into the first openings and can be brought into the region of the first clamping surfaces.

It can be provided that the first and, if present, the second perforations are designed as round openings in the side wall areas, in particular as circular bores or punched out areas.

The clamping element can have an elongated, transverse lever shaft with a non-circular cross-sectional shape. The lever shaft can carry the first and second fastening surfaces on its outer circumference and can be rotatable about a transverse axis of rotation between the release and clamping positions.

The lever shaft can have a circular cross-sectional shape provided with flattened portions lying opposite one another, in particular arranged parallel to one another, wherein the circumferential regions lying between the flattened portions form the first and second fastening surfaces.

If the first openings adjacent to the first clamping surfaces are designed as undercuts and have an opening, it can be provided that the clamping element has an elongated lever shaft running in the transverse direction, on the outer circumference of which the second fastening surface is designed to interact with the second carrier profile, wherein a clamping projection is arranged on the lever shaft in the region of the first openings, which clamping projection is designed radially eccentrically with respect to a longitudinal axis of the lever shaft and forms the first fastening surface.

The clamping element can be formed from two separately formed partial clamping elements, wherein each partial clamping element interacts with a first clamping surface and an immediately adjacent second clamping surface.

1 to 5 explain a first embodiment of the invention, wherein the connection arrangement shown here comprises three elements, namely a first carrier profile 10, a second carrier profile 40 and a clamping lever 60 forming a clamping element. The first carrier profile 10 in this embodiment has a closed rectangular cross-sectional profile, with parallel side walls 10a, which form side wall regions, and a bottom wall 10b, which forms a transverse wall region of the first carrier profile 10. An inner side of the bottom wall 10b forms a first contact surface 11. Furthermore, the first carrier profile 10 has a cover wall 10c, which can be designed identically to the bottom wall 10b due to the symmetry of the profile. The entire carrier profile extends elongated in a longitudinal direction 12, wherein the walls of the first support profile 10 enclose a cavity 14.

The side wall regions or side walls 10a are each provided with a first opening 16, wherein the first openings 16 are opposite one another in a transverse direction 18, perpendicular to the longitudinal direction 12.

The first openings 16 each have an inner surface 19 extending over their inner circumference, wherein a part of this inner surface 19, which is located away from the first support surface 11 or the bottom wall 10b, forms a first clamping surface 20.

In this exemplary embodiment, the first openings 16 and thus also the inner surface 10 do not run along a closed circumferential path, but the first openings 16 have an opening 22 pointing in the longitudinal direction 12 and away from the transverse wall region or the bottom wall 10b, which serves, in a manner to be explained below, to enable the clamping lever 60 to be inserted.

The connection arrangement further comprises a second carrier profile 40, the cross-sectional area of which is designed such that it can be inserted in a form-fitting manner in the longitudinal direction 12 into the cavity 14 of the first carrier profile 10. In the exemplary embodiment shown, the second carrier profile 40 is rectangular in cross-section, with two parallel side walls 42 that form side wall regions, a base wall 44 and a cover wall 46 that extend elongatedly in the longitudinal direction 12. An outer surface of the base wall 44 forms a second contact surface 45, which, when the carrier profiles are inserted into one another, is opposite or rests against the first contact surface 11 in a clamping direction 24 that runs perpendicular to the longitudinal and transverse directions 12, 18.

The second support profile 40 is provided with several slot-like recesses 48 which are open at the ends and form second openings and are arranged at predetermined mutual distances. Each recess 48 extends through the top wall 46 and part of the side walls 42 and has an inner surface 48a, the area of which lying closest to the bottom wall 44 forms a second clamping surface 50 which is cylindrical in shape in this embodiment.

2 shows how the second carrier profile 40 is inserted with an end section into the cavity 14 of the first carrier profile 10, wherein one of the slot-shaped recesses 48 is located in the region of the opening 22 adjacent to the first openings 16.

The clamping lever 60 can now be inserted into the slot-shaped recess 48 and the opening 22, as shown in 3 is shown. In this embodiment, the clamping lever 60 has a cylindrical lever shaft 62, which is oriented with its axial direction in the transverse direction 18, and a hand lever 64 fixed to it. The lever shaft 62 has a diameter that corresponds to a width of the slot-shaped recess 48 in the second carrier profile 40. The second clamping surfaces 50 correspond in terms of their radius of curvature to the diameter of the lever shaft 62, so that a flat contact of the lever shaft on the second clamping surfaces 50 is ensured.

The clamping lever 60 further comprises two clamping projections 66, which are arranged on the lever shaft 62 at each end and thus in the region of a side wall 10a of the first carrier profile 10 when the clamping lever is inserted, so that the clamping projections 66 can come into engagement with the first clamping surfaces 20 of the first carrier profile 10.

First fastening surfaces 68 are formed on the clamping projections 66 on the clamping lever 60, which are opposite the first clamping surfaces 20 when the clamping lever is inserted, and second fastening surfaces 70, which are formed by parts of the outer peripheral surface of the lever shaft 62 and are opposite the second clamping surfaces 50 of the second support profile 40 when the clamping lever 60 is inserted.

3 and 4 explain the insertion and the inserted state of the clamping lever 60, in particular 4 show the interaction of the clamping projections 66 with the first clamping surfaces 20 of the first openings 16 of the first support profile 10.

In particular 5 shows, in this embodiment the hand lever 64 including the clamping projections 66 is cut out of a region of the first carrier profile 10, so that maximum material utilization and savings are possible.

When transferring the connection arrangement from one to 4 shown release position into a 5 In the clamping position shown, after inserting the clamping lever 60 through the opening 22 in the first carrier profile 10, the second carrier profile 40 is initially displaced relative to the first carrier profile 10 in the longitudinal direction 12 so that the clamping projections 66 of the clamping lever reach the first openings 16. The positioning of the first Fastening surfaces 68, the second fastening surfaces 70, the first clamping surfaces 20 and the second clamping surfaces 50 is selected so that when the clamping lever 60 is transferred from the 4 shown release position into the 5 In the clamping position shown, the carrier profiles are displaced relative to one another in the clamping direction 24 or at least firmly applied against one another and a clamping force is generated between the first clamping surfaces 20 and the first fastening surfaces 68, between the second fastening surfaces 70 and the second clamping surfaces 50 and between the first contact surface 11 and the second contact surface 45 of the carrier profiles 10 and 40, wherein the contact surfaces are pressed against one another, ie the outside of the bottom wall 44 of the second carrier profile 40 is pressed against the inside of the bottom wall 10b of the first carrier profile 10.

6 to 11 explain a second embodiment of the invention, in which the first and second support profiles 110, 140 have a rectangular cross-section as in the first embodiment and are designed as rectangular profiles running in the longitudinal direction 112.

In this embodiment, the second clamping surfaces 150 are not formed by slot-shaped recesses as in the first embodiment, but by holes 148 that are aligned with one another in the transverse direction 118, with parts of inner surfaces 148a of the holes 148 that are located next to a bottom wall 144 of the second support profile 140 forming the second clamping surfaces 150. The holes 148 form second openings in the second support profile 140.

The first support profile 110 is provided with first openings 116 in the form of bores opposite one another in the transverse direction 118, which have inner surfaces 119, the regions of which pointing away from a bottom wall 110b of the first support profile 110 form first clamping surfaces 120.

As in the first embodiment, the tension lever 160 comprises a lever shaft 162 and a hand lever 164. The lever shaft 162 is cylindrical with two flats lying parallel to one another, the cylindrical surfaces remaining between the flats forming a first fastening surface 168 and a second fastening surface 170.

The hand lever 164 is shaped such that it grips the first support profile 110 in a form-fitting manner when in the clamping state.

The first openings 116 are positioned in the first carrier profile 110 so that in the assembled state of the connection arrangement ( 7 ), in which the first and second contact surfaces 111, 145 are still arranged with play or at a small mutual distance, in any case still without clamping force, are aligned with the second openings in the second support profile 140, which form the second openings, and are arranged partially overlapping one another when viewed in the transverse direction 118.

10 and 11 explain the arrangement in the release position, where 11 a cross section through the connection arrangement along the lever shaft 162 ( 10 ) shows. In order to generate a force flow of a clamping force from the first carrier profile via the clamping lever to the second carrier profile in the clamping position of the clamping lever 160, the first clamping surfaces 120 come into contact with the first fastening surfaces 168 of the clamping lever and the second fastening surfaces 170 of the clamping lever come into contact with the second clamping surfaces 150 of the second carrier profile 140. As in 11 As shown, in the release position there may still be a distance or play between the first clamping surfaces 120 and the lever shaft 162 on the one hand and the lever shaft 162 and the second clamping surfaces 150 on the other hand, and/or a distance between the contact surfaces 111, 145. Thus, the lever shaft 162 or the clamping lever 160 can be easily inserted into the openings 116 and 148 in its release position, as shown in 7 , 8th is shown.

When the clamping lever 160 is turned a quarter turn into the clamping position according to 12 or. 13 the first fastening surfaces 168 come into contact with the first clamping surfaces 120, the second fastening surfaces 170 come into contact with the second clamping surfaces 150 and the first contact surface comes into contact with the second contact surface, which in section 13 As a result, a force flow is generated between the first clamping surfaces 120 and the first fastening surfaces 168, the second fastening surfaces 170 and the second clamping surfaces 150 and between the contact surfaces, which clamps the support profiles against one another, so that the bottom wall 144 of the second support profile is pressed against the bottom wall 110b of the first support profile, thereby achieving a play-free, positive and non-positive connection between the support profiles.

14 to 21 explain a third embodiment of the invention, which differs from the second embodiment only in that the support profiles are open profiles with a U-shaped cross section. 14 shows the profiles in a state not yet connected and 15 together, with two openings 216, 248 adjacent, whereby they are in Seen transversely, they partially or largely overlap so that the clamping lever 260 can be inserted, which 16 shows. 17 shows the arrangement with the clamping lever rotated by 90° in the clamping position.

19 shows a cross-sectional view of the arrangement in the release position through the lever shaft 262 of the clamping lever 260, according to 18 , whereby there is still play in the area of the first clamping surfaces 220 and the clamping shaft 262 on the one hand and in the area of the second clamping surfaces 250 and the clamping shaft 262 on the other hand. The first and second contact surfaces 211, 245 lie loosely against one another without any mutual clearance.

21 shows a cross-sectional view of the arrangement in clamping position, according to 20 , similar 19 , with the clamping lever 260 rotated by 90°. The first and second fastening surfaces 268, 270, which are formed by the flats of the otherwise cylindrical clamping shaft 262, rest against the first and second clamping surfaces 220 and 250 under a clamping force. The first and second contact surfaces also rest firmly against one another or are pressed against one another under the clamping force.

22 to 29 explain a fourth embodiment of the invention, which differs from the third embodiment only in that instead of a single, uniform clamping lever, this is split and thus two partial clamping levers 360a, 360b are provided. Each partial clamping lever comprises a lever shaft 362 and a hand lever 364 for manual actuation. This embodiment can be advantageous if the installation of a continuous lever shaft is difficult or not possible, or in order to divide the clamping process into two partial processes.
