Description

The invention relates to a mounting arrangement which comprises a longitudinal beam and a mounting element which is detachably attached to the longitudinal beam without tools. Such an arrangement or assembly can advantageously be used as a basis for the construction of shelves, tables and other load-bearing arrangements by attaching further fastening or supporting elements, such as a support column, to the mounting element.

The object of the invention is to create a structurally simple and yet load-bearing connection between a longitudinal member and a mounting element held thereon, whereby both elements should be able to be connected to one another in a positive and non-positive manner without the use of tools, i.e. by hand, in order to achieve maximum assembly precision and ensure force absorption capacity.

This object is achieved by a mounting arrangement with a longitudinal beam with a mounting element according to claim 1 which is detachably attached to it without tools.

The longitudinal beam has two support elements extending in a longitudinal direction, which are arranged opposite one another at a distance from one another and form a receiving space between them for receiving the mounting element. The longitudinal beam is expediently designed to be mirror-symmetrical with respect to a longitudinal center plane of the longitudinal beam. The support elements are preferably designed in mirror images with respect to the longitudinal center plane.

A connecting element running transversely to the longitudinal direction is arranged in an end region of the longitudinal beam or in end regions of the support elements. In a fastening state, a first side of the mounting element is arranged adjacent to a first support element and a second side of the mounting element, which is opposite the first side, is arranged adjacent to a second support element, wherein a front region of the mounting element is arranged adjacent to the connecting element and a rear region of the mounting element is arranged facing away from the end regions of the support elements.

In the rear region of the mounting element, a first locking means for positively fixing the rear region of the mounting element on the longitudinal beam is arranged, and in the front region of the mounting element, a second locking means for positively fixing the front region of the mounting element on the longitudinal beam is arranged.

One of the locking means or both or the connecting element forms a longitudinal stop for the mounting element, wherein the first and second locking means are designed so that they can be activated by inserting the mounting element into the receiving space and moving the mounting element in a mounting direction, relative to the longitudinal beam in the direction of the connecting element , can be brought into mutual engagement up to the stop and into a locking position corresponding to the fastening state, in which the mounting element is held in a form-fitting manner on the longitudinal beam and can only be detached from the longitudinal beam by moving against the mounting direction.

According to the invention, a clamping means is arranged on the longitudinal beam for applying a clamping force acting on the mounting element in the assembly direction, the clamping means being in a release position in which no clamping force acts on the mounting element and this can be inserted into or detached from the longitudinal beam, or into a Clamping position, in which the mounting element rests against the longitudinal stop and is positively and non-positively fixed in the locking position on the longitudinal member, can be brought, the clamping means having a clamping element that can be inserted into the longitudinal member without tools and clamped against the mounting element.

The construction according to the invention ensures a positive and non-positive fastening of the mounting element in a predetermined fastening or locking position on the longitudinal beam, whereby both the insertion process of the mounting element and the tensioning or locking process of the mounting element on the longitudinal support can be carried out by hand alone without the aid of a tool . Of course, dismantling in the reverse order is also possible without tools.

The first locking means preferably comprises a first locking element arranged on each support element and a second locking element arranged on each side of the mounting element, with a first locking element being in engagement with a second locking element in the fastening state.

It can be provided that each first locking element is formed by a slot-like recess in the respective support element, which extends at least partially or with a directional component in the longitudinal direction, and each second locking element is formed by a projection arranged on the mounting element and projecting transversely to the longitudinal direction , or conversely, each first locking element is formed by a projection and each second locking element is formed by a recess arranged in the mounting element.

Furthermore, it can be provided that the second locking means comprises a third locking element arranged on each support element and a fourth locking element arranged on each side of the mounting element, with a third locking element being in engagement with a fourth locking element in the fastening state. In this case, every third locking element can be formed by a slot-like recess in the respective support element, which extends at least partially or with a directional component in the longitudinal direction, and every fourth locking element can be formed by a projection arranged on the mounting element and projecting transversely to the longitudinal direction, or vice versa every third locking element can be formed by a projection and every fourth locking element can be formed by a recess arranged in the mounting element.

The recesses can be L-shaped with a first insertion section that runs perpendicularly or obliquely to the longitudinal direction and an adjoining locking section that runs obliquely to or in the longitudinal direction.

The projections can be formed by protruding sheet metal sections or cylindrical bolt heads.

Each support element can comprise a support wall running in the longitudinal direction, for example made of sheet metal, on which the first and possibly the third locking elements are arranged.

The supporting walls can be connected by a floor element, for example a sheet metal crossbar, to form a profile with a U-shaped cross section.

Each support element can be designed as a support profile running in the longitudinal direction, for example an L-, U- or closed box-shaped sheet metal profile, the mutually facing sides of which form the support walls. The support elements or support profiles can be attached at their end regions to a cross member forming the connecting element. The cross member is expediently designed as a sheet metal profile and preferably has recesses for pluggable fastening of the support elements, which in turn are provided in their end regions with suitable projections for insertion into the recesses. This pluggable attachment is done without tools.

It is expediently provided that the supporting walls are arranged parallel to one another.

As an alternative to a cross member, it can be provided that the support elements are connected to one another by an end wall that delimits the receiving space, runs transversely to the longitudinal direction and forms the connecting element.

The longitudinal stop can be formed by the cross member, by the end wall or by the projections and by end regions of the locking sections of the recesses.

It can be provided that the second locking means is formed by the cross member, which has an opening for positively receiving the front region of the mounting element.

In a variant, it can be provided that the first locking means comprises a first intermediate piece, which positively engages around the rear region of the mounting element and has a second locking element arranged on each side of the intermediate piece, which interacts with a first locking element arranged on the support elements.

Furthermore, it can be provided that the second locking means comprises a second intermediate piece, which positively engages around the front region of the mounting element and has a third locking element arranged on each side of the intermediate piece, which interacts with a fourth locking element arranged on the support elements. The first and/or second intermediate piece can be bent from sheet metal, wherein the second and/or fourth locking element can be a protruding sheet metal section.

It is preferably provided that the cross member extends in both directions transversely to the longitudinal direction beyond the support elements. In a practical application, the cross member can be used, for example, to support a table top.

The mounting element can be designed for releasably, in particular tool-free, fastening of a support column arranged perpendicular to the longitudinal direction, it being preferably provided that the support column extends perpendicular to a mounting plane defined by cross and longitudinal beams. In practice, the support column can form a table base, for example.

At least one protective element can be provided on the mounting element in order to protect one to prevent direct contact of the clamping device with a surface of the mounting element. Two protective elements can be provided in the area of the first locking element, each of which is held by bolts that carry the bolt heads. If the bolt is designed as a locking bolt, the protective element can be designed in one piece with an associated bolt.

In a variant, it can be provided that the clamping means comprises a thread-adjustable clamping member, which can be placed against the mounting element by turning it manually and thus tensions the mounting element non-positively against the longitudinal stop.

In another variant, it is provided that the clamping means comprises a clamping lever which is pivotally mounted on the support elements and has a first lever arm for manual actuation and a second lever arm for abutting against the mounting element in order to tension the mounting element against the longitudinal stop. The tensioning lever can be mounted in opposite bearing openings of the support elements and can expediently be inserted into the bearing openings after inserting the mounting element into the receiving space.

If the first and second locking elements are formed by a respective recess in the support elements, it can be provided that the bearing openings are formed as parts of the recesses that form the first and second locking elements.

The tensioning lever can advantageously have a releasable locking element which, in the tensioning state, cooperates with at least one of the support elements in order to prevent unintentional loosening of the tensioning lever. For this purpose, a spring-loaded locking pin which is movable transversely to the longitudinal direction can be mounted in the first lever arm of the tensioning lever, which is expediently arranged transversely to the longitudinal direction, and which engages in a corresponding opening in one of the support elements in the clamping state.

Further advantages and features of the invention result from the following description of a total of five variants, with these taking into account the specific design of the longitudinal beam (supporting elements as flat supporting walls or as box-shaped profiles, with or without bottom wall), of the connecting element (cross beam, end wall or second intermediate piece), the first locking means (bolt heads on the mounting element or separately formed first intermediate piece) and the second locking means (opening in the cross member, bolt heads on the mounting element or separately formed second intermediate piece).

First is on 1 until 6 Reference is made, in which a first embodiment of the invention is explained, as well as 7 until 13 , in which essential parts of the arrangement are enlarged and shown in more detail.

In the 1 until 13 The arrangement shown initially comprises two support elements 102, 104 forming a longitudinal beam 100, which are pluggably connected to a cross member 106. In this embodiment, the support elements 102, 104 are designed as box-shaped profile elements with a closed cross section, which extend in a longitudinal direction 108 and are arranged opposite one another at a predetermined distance from one another.

For a pluggable, positive connection to the cross member 106, the support elements 102, 104 each have two T-shaped projections 110 with receiving slots 112 in their end regions 102a, 104a that point to or are adjacent to the cross member 106. The cross member 106 is in turn provided with corresponding recesses 114, into which the projections 110 can be inserted by moving relative to the cross member in an assembly direction 109, in the longitudinal direction 108 towards the cross member, and then moving transversely to the longitudinal direction, as 8th and 9 show in detail. A width of the receiving slots 112, seen in the longitudinal direction 108, corresponds to the local wall thickness of the cross member 106 in the area of the recesses 114, which is preferably a metal or steel sheet. Alternatively, plastic profiles are possible for forming the support elements and/or the cross member.

After inserting the support elements 102, 104 into the cross member 106 in the assembly direction 109 according to 8th and a movement of the support elements transversely to the longitudinal direction 108 9 These are fixed in a form-fitting manner on the cross member 106. In this position, the support elements 102, 104 form the longitudinal support 100 and the cross support forms the connecting element, with a receiving space 118 for receiving a mounting element 120 being formed between the support elements. In the exemplary embodiment shown, the mounting element 120 is connected to a support column 122, which in the assembled state is arranged perpendicular to the plane 124 defined by the longitudinal and cross members. When the mounting arrangement is used as a table, the support column 122 forms part of a first table base, and at ends of the support elements 102, 104, not shown, opposite the cross support 106, a further cross support with a second table base is arranged in a corresponding manner, a table top being held on the cross supports can be. How beyond that 10 and the other representations suggestive As can be seen, the support column 122 preferably comprises a plurality of telescopic elements 126, 126 ', 126'', so that the table formed with it is height-adjustable.

The mounting element 120 has a front region 130, which in the assembled state faces the cross member 106 or is partially enclosed by a receiving opening 146 of the cross member 106, and a rear region 132, which is surrounded by the cross member or the end regions 102a, 104a of the support elements is directed away.

As in 2 is shown, threaded openings 134 are provided in the rear area 132 of the mounting element 120, into which screw bolts 136 with cylindrical bolt heads 138 are screwed. The screw bolts 136 fix protective caps 140 on the mounting element 120, the purpose of which is explained below. Alternatively, instead of screw bolts, locking bolts can be provided, which can be inserted into corresponding holes. In such a design, the protective caps can be formed in one piece with the locking pins.

Threaded openings 134 are also provided in the front area 130 of the mounting element 120, which are used in other embodiments to accommodate screw bolts, or bores to accommodate socket bolts, as mentioned above.

The mounting element 120 prepared in this way is according to 3 inserted into the receiving space 118, the bolt heads 138 engaging in L-shaped recesses 142 of the support elements 102, 104. The support elements 102, 104 are designed and arranged in mirror images with respect to a longitudinal center plane 144, so that the recesses 142 lie exactly opposite one another. The mutually facing walls of the support elements 102, 104, in which the recesses 142 are formed, form support walls 102b, 104b of the longitudinal beam 100.

Each L-shaped recess 142 forms a first locking element, and each associated bolt head 138 forms a second locking element, with both locking elements forming a first locking means arranged in the rear region 132 of the mounting element 120.

A second locking means is arranged in the front region of the mounting element 120 and is formed by the front region 130 itself and by the receiving opening 146 of the connecting element or cross member 106 that receives it. The receiving opening 146 receives the front region 130 of the mounting element 120 in a form-fitting manner or encloses it in a form-fitting manner when the mounting element 120 is inserted into the receiving space 118 ( 3 ) and is shifted in the assembly direction 109 ( 4 ).

The first locking means or the second locking means or both or the cross member 106, which forms the connecting element in this embodiment, form a stop for the mounting element 120 with respect to its displacement in the mounting direction 109.

The L-shaped recess 142, which is formed in each support element 102, 104, has an insertion section 142a which runs perpendicular to the longitudinal direction and which enables the mounting element or the bolt heads 138 to be inserted vertically from above into the receiving space 118. The insertion section 142a is adjoined in the mounting direction 109 by a locking section 142b, which runs in the longitudinal or mounting direction 108, 109 and enables the mounting element to be displaced in the mounting direction 109.

A front end 142c of the recess 142, viewed in the assembly direction, can act as a stop for the bolt heads 138 or the mounting element 120.

In a state largely displaced in the assembly direction, the mounting element 120 is in a locking position corresponding to a fastening state, in which both the first locking means positively fixes the rear region of the mounting element to the longitudinal member and the second locking means positively locks the front region 130 of the mounting element 120 to the Cross member 106 or the connecting element is fixed. The mounting element is thus held in a form-fitting manner on the longitudinal beam and on the connecting element or cross beam and can only be released from it by moving against the mounting direction.

How 5 and 11 further show, according to the invention and for the precise, non-positive locking of the mounting element on the longitudinal member, a clamping device is provided, which comprises a clamping element in the form of a clamping lever 150. The tensioning device or the tensioning lever serves to apply a tensioning force acting on the assembly element 120 in the assembly direction and, according to the invention, comprises a tensioning element which can be inserted into the longitudinal beam 100 without tools and can be clamped against the assembly element 120. The clamping element or the clamping lever 150 is U-shaped in the illustrated embodiment and has two first lever arms 152 for manual actuation and two second lever arms 154 for abutting against the mounting element 120 on. At the transition between the first and second lever arms, screw bolts with bolt heads 156 are screwed in, the bolt heads 156 being inserted into the recesses 142 and being accommodated in bearing openings 158, which are formed as part of the recesses 142 in this embodiment. Alternatively, separate bearing openings can be provided in the support elements 102, 104 for storing the clamping lever 150.

A connecting piece 160 connects the first lever arms 152 and is used for manual actuation of the clamping lever 150, a releasable locking device 162 being arranged in the connecting piece 160, which has a locking element 164 spring-loaded in the transverse direction for engagement with locking recesses 168 provided for this purpose in the support elements. The locking element 164 can be released from engagement with the locking recesses 168 by a protruding actuation lug 166. This prevents the clamping lever from being released unintentionally.

12 shows the mounting element 120 in a fastening state or the locking position with respect to the longitudinal and cross members with the tensioning lever inserted into the recesses 142, the second lever arms 154 of the tensioning lever 150 not yet being in engagement with the mounting element 120. The protective caps 140 on the mounting element 120 can also be seen here 2 and 10 , which are made of plastic, for example, and protect the surface of the mounting element from damage by the clamping lever and at the same time reduce the friction between the clamping lever and the mounting element and enable smooth operation.

When the clamping lever 150 is pivoted down, in which the connecting piece 160 is located between the support elements, the mounting element 120 is clamped in a non-positive manner against the stop and in relation to the support elements and the connecting element and is thus fixed to them in a non-positive and positive manner.

14 until 18 explain a second embodiment of the invention, in which, in contrast to the first embodiment, the support elements 202, 204 are fixed to one another by means of an end wall 206, instead of being plugged into a cross member and fixed to it.

14 shows two support elements 202, 204, which form a longitudinal beam 200 and are firmly connected to one another at a predetermined mutual distance at their end regions 202a, 204a on an end wall 206 running transversely to the longitudinal direction 208.

In the mutually facing support walls 202b, 204b of the support elements 202, 204, two recesses 242 are arranged at a mutual longitudinal distance, instead of just one recess as in the first embodiment. In addition, a separate bearing opening 258 is provided for the tensioning lever 250.

How 15 shows, two screw bolts 236 (alternatively: locking bolts, as mentioned in the first embodiment) with bolt heads 238 are provided on each side of the mounting element 220, which engage in a total of four recesses 242. As a result, a first locking means comprising a recess and a bolt head on each side is formed in the rear region 232 of the mounting element and a second locking means comprising a recess and a bolt head on each side is formed in the front region 230 of the mounting element.

How 16 shows, when inserted into the receiving space 218 with the bolt heads 238, the mounting element 220 first comes into engagement with the insertion sections 242a of the recesses 242 and then by moving in the mounting direction 209 with the locking sections 242b, until against a stop, which is either through the end wall 206 or through Ends 242c of the locking sections 242b are formed.

The design of the tensioning lever 250 and the bracing of the mounting element 220 corresponds to the first embodiment, with the slight difference that, as stated, the bearing openings 258 for the bolt heads 256 of the tensioning lever are not part of the recesses 242, but as separate recesses in the support elements 202, 204 are trained.

19 until 22 explain a third embodiment of the invention. The arrangement of support elements 302, 304 to form a longitudinal beam 300 by inserting their end regions 302a, 304a into a cross beam 306 corresponds to the first embodiment. In contrast to this, in this case the mounting element 320 does not have any screw bolts with bolt heads, but rather is in its rear area 20 locked in a form-fitting manner on the support elements 302, 304 by an intermediate piece 340. For this purpose, the mounting element 320 is first inserted into the receiving space 318 and, by moving it in the mounting direction 309, its front region 330 is inserted into a receiving opening 346 of the cross member 306, so that the front region 330 is received in a form-fitting manner in the cross member 306. The second locking means is thus formed, as in the first embodiment, by the cross member 306 and the front region 330 of the mounting element 320.

The first locking means is formed by the rear region 332 of the mounting element, the intermediate piece 340 which receives it in a form-fitting manner, and by projections 341 of the intermediate piece 340 which interact with recesses 342 in the support elements 302, 304.

How 20 shows, the projections 341 first engage in insertion sections 342a of the recesses 342 and then reach locking sections 342b by displacing the intermediate piece 340 together with the mounting element 320 in the mounting direction 309. This means that the rear area 332 of the mounting element is also held in a form-fitting manner on the longitudinal beam 300.

According to 21 The configuration of the clamping lever 350 essentially corresponds to the first and second embodiments, and the process of inserting it into the recess 342 corresponds to the first embodiment. The bearing openings 358 are formed as part of the recesses 342, although a separate design as in the second embodiment would also be possible here.

The fully assembled, positively and non-positively received position of the mounting element 320 and locked on the longitudinal and cross members according to 22 with the clamping lever 350 folded corresponds to the first embodiment, with the difference that the second lever arms 354 of the clamping lever do not press directly against the mounting element 320, but against the intermediate piece 340, which in turn is pressed against the mounting element 320.

23 until 27 explain a fourth embodiment of the invention, in which initially the longitudinal beam 400 is not formed by two separate support elements, but rather in one piece by a support profile with a U-shaped cross section. In other words, the support elements 402, 404 in this embodiment consist of a respective support wall 402b, 404b, which are connected to one another by a base element 411 to form a U-profile. The longitudinal beam 400 is expediently designed as a sheet metal profile. How 23 shows, the support elements 402, 404 have projections 410 at their end regions 402a, 404a, similar to the support elements 102, 104 of the first embodiment. The cross member 406, which forms the connecting element in this embodiment, has matching recesses 414, so that the projections 410 can be inserted into the cross member 406 by slightly compressing the U-profile transversely to the longitudinal direction 408 and then shifting in the assembly direction 409, whereby the After the support walls have been spring apart, projections 410 engage in a form-fitting manner in the recesses 414.

How 24 until 27 show, corresponds to the insertion of the mounting element 420 into the longitudinal beam 400, the positive gripping of a front region 430 of the mounting element through a receiving opening 446 of the cross member 406, the insertion of an intermediate piece 440 with bolt heads 438 in recesses 442 of the longitudinal beam 400 and the insertion and locking of a Clamping lever 450 essentially of the third embodiment.

28 until 32 finally explain a fifth embodiment of the invention, which differs from the previous embodiments in that the longitudinal beam 500 in the form of two support elements 502, 504 does not yet have a cross member or any other connecting element before the mounting element 520 is inserted. Similar to the third and fourth embodiments, there is a positive connection between the mounting element 520 and the support elements 502, 504 through intermediate pieces 540a, 540b, whereby, in contrast to the previous embodiments, there are not just one but two intermediate pieces.

A first intermediate piece 540a positively engages over a rear region 532 of the mounting element 520, and a second intermediate piece 540b positively engages over a front region 530 of the mounting element. Each intermediate piece is provided with projections 541 pointing transversely to the longitudinal direction 508 for engagement in and positive interaction with corresponding recesses 542 in the support elements 502, 504. Similar to the previous embodiments, the recesses 542 are L-shaped with an insertion section 542a running perpendicular to the longitudinal direction and a locking section 542b running in the longitudinal or mounting direction. In contrast to the other embodiments, here two pairs of projections 541 are provided on each side of each intermediate piece, and two matching pairs of recesses 542 arranged adjacent to one another, spaced apart in the longitudinal direction, are formed in each support element.

Each projection 541 forms a receiving slot 542d for receiving a section of the supporting wall 502b, 504b of the respective supporting element 502, 504, a width of the receiving slot corresponding to the local wall thickness of the respective supporting wall, so that after insertion of the mounting element with both intermediate pieces transverse to the longitudinal direction ( 30 , left illustration) and then moving in assembly direction 509 ( 30 , right illustration) the intermediate pieces 540a, b are positively connected to the support elements 502, 504.

In this embodiment, the front intermediate piece 540b forms a connecting element of the support elements.

The insertion of a clamping lever 550 and the tensioned, positive and non-positive connection between the mounting element and the longitudinal beam or the support elements 31 , 32 corresponds to the previous embodiments.
