MOUNTING DEVICE

Description

[0001] The invention relates to an assembly device for mounting furnishings. In particular, the invention relates to an assembly device for mounting sanitary and kitchen furnishings such as washbasins and undermount sinks.

[0002] Installing undermount sinks and washbasins has traditionally required a significant amount of manpower and physical effort. Typical undermount sinks and washbasins weigh up to 30 kg, which must be carried by at least one installer during installation, while another installer secures the sink or washbasin.

[0003] Document US3247588A discloses a mounting device with a support element that can be held on a threaded rod and is pivotable and arranged off-center to the threaded rod.

[0004] The invention is based on the objective of creating an assembly device and an assembly system with the assembly device that reduces the effort required for assembling furnishings and enables safe assembly.

[0005] According to the invention, the problem is solved by an assembly device according to claim 1.

[0006] The mounting device according to the invention particularly facilitates lifting and holding the furnishings to be mounted in their mounting position. The reduced radial extension of the support element in the first position allows the support element to be guided from above through a drain opening of the furnishing to be mounted, through which wastewater will subsequently flow into a connected wastewater pipe during use of the furnishing. The support element can then be moved into the second position, in which it no longer needs to be guided through the drain opening. As soon as the support element rests against the furnishing from below, lifting the support element, particularly together with the longitudinal element, lifts the furnishing and guides it into the mounting position.

[0007] To facilitate lifting, the support element can be positioned above the furniture item before lifting, with the longitudinal element extending through the entire item, particularly in the vertical direction. The support element allows the mounting device and the furniture item to be braced against a fixed element at the desired mounting position, such as that of the building in which the furniture item is to be installed. The furniture item can then be lifted onto the support element by shifting the support element relative to the longitudinal element in the longitudinal direction. This allows the furniture item to be held in place by a single lifter without requiring any physical effort.

[0008] The longitudinal element has a cross-section that is at least substantially uniform along its longitudinal direction. In particular, the longitudinal element has a cross-section that is at least substantially rotationally symmetrical with respect to its longitudinal center axis. The longitudinal direction is parallel to the longitudinal center axis. The longitudinal element has a length of at least 40 cm, preferably at least 50 cm, and most preferably exactly 52 cm, and a diameter of at most 30 mm, preferably at most 20 mm, and most preferably exactly 16 mm.

[0009] The support element is arranged on the longitudinal element such that a force acting on the support element in the second position from the direction of the support element is transferred to the longitudinal element. Preferably, the force prevents the support element from moving into the first position on its own and / or necessarily holds it in the second position. Preferably, the support element rests directly against the longitudinal element in at least one of the positions and / or is attached to the longitudinal element by means of an auxiliary device. The support element and / or the longitudinal element are preferably at least substantially dimensionally stable and / or made of a metal.

[0010] The support element projects radially from the longitudinal element with respect to the longitudinal center axis. Preferably, the longitudinal element extends through a continuous recess in the support element. According to the invention, the distance between the support element and the support element is smaller in the first position than in the second position when the support element remains stationary relative to the longitudinal element.

[0011] According to the invention, the support element is pivotably mounted on the longitudinal element about a pivot axis. For this purpose, the longitudinal element and / or the support element preferably has a bore perpendicular to the longitudinal center axis, through or into which a bearing element, in particular a screw, a pin, or a stud, extends. Such a mounting of the support element on the longitudinal element is structurally simple to implement and thus increases the reliability of the assembly device.

[0012] The support element is preferably pivotable by at least 45°, more preferably by at least 60°, and further preferably by at least 70° relative to the longitudinal element about the support element pivot axis. In particular, it is pivotable from the second position to the first position and / or back by the aforementioned angle. This allows the radial extent of the support element relative to the longitudinal center axis to be varied over a particularly wide range, thus enabling the mounting device to be used safely for furnishings with drain openings of varying sizes.

[0013] According to the invention, the support element has a center of gravity that is spaced apart from the pivot axis of the support element and from the longitudinal center axis. This applies particularly at least in the second position. This ensures that the support element automatically aligns itself in the first position when the longitudinal element is oriented at least substantially vertically, and can therefore be easily guided through drain openings. The support element can then be easily moved into the second position, in particular by moving the longitudinal element radially within the drain opening. In this direction, a side of the support element that is pivoted upwards in the first position projects from the longitudinal element and is then moved upwards, causing this side to rest against the fixture. With a further upward movement of the longitudinal element, the support element is then moved from the fixture into the second position.

[0014] Preferably, the support element extends in a first direction perpendicular to the longitudinal center axis at least one and a half times, preferably at least twice, and particularly preferably at least two and a half times, and optimally three times, as far as the support element extends in a second direction perpendicular to both the longitudinal center axis and the first direction. In particular, the pivot axis of the support element extends in the second direction. Such an elongated design of the support element makes it particularly easy to achieve the effect of changing how far the support element projects from the longitudinal center axis in the different positions.

[0015] Preferably, the support element extends from the support element pivot axis in the first direction at least substantially as far as it extends in the opposite direction to the first direction from the support element pivot axis. InIn the second direction, the support element extends in particular by a maximum of 7 cm, preferably by a maximum of 6 cm, and most preferably by a maximum of 5 cm, in order to be easily guided through various drainage openings. For the sake of sufficient stability, the thickness of the support element is preferably 10 mm.

[0016] Preferably, the support element surrounds the longitudinal element on two opposite sides. In particular, when considering the mounting device in the longitudinal direction, the pivot axis of the support element first intersects a portion of the support element, then the longitudinal element, and subsequently another portion of the support element, disregarding any bearing element that may be present. This enables a more reliable force transmission from the support element to the longitudinal element. Preferably, the support element completely surrounds the longitudinal element or its longitudinal center axis. In particular, the support element has a continuous recess through which the longitudinal element extends. This recess is preferably perpendicular to the pivot axis of the support element in the second position, or elongated in the first direction. In this respect, the recess is preferably an elongated slot.This allows the support element to pivot with a simple structural design and a small distance between the support element and the longitudinal element in the area of ​​the support element pivot axis.

[0017] The support element preferably has a contact surface for contact with the furniture to be mounted. At least in the second position, the contact surface is at least partially oriented towards the support element. Preferably, the contact surface is made of a flexible material. This material is, in particular, part of the support element. This material is, in particular, an elastomer or a textile such as felt, which is applied as a layer to a particularly rigid and / or harder body of the support element. This prevents scratching of the underside of the furniture, against which the support element rests during installation, without compromising the stability of the support element.

[0018] Preferably, the contact surface is curved, at least in sections. In particular, the contact surface has a first contact surface section extending at right angles to the longitudinal center axis in the second position and being at least partially flat, and / or a second contact surface section extending at an angle of less than 90° to the longitudinal center axis or parallel to it in the second position and being at least partially flat. In particular, the aforementioned contact surface sections are connected to one another by means of an intermediate section that appears curved when viewing the support element in the direction of the support element's pivot axis. This allows the aforementioned contact surface sections to transition smoothly and seamlessly into one another. In particular, the first contact surface section is angled relative to the second contact surface section by at least the angle by which the support element can pivot from the second position to the first position.This ensures that the furnishing is not scratched even when the supporting element, as described above, is placed against the furnishing from below in its first position and is passively moved into the second position by the furnishing and by pulling up the longitudinal element, as described above.

[0019] Preferably, the pivot axis of the support element is arranged between the center of gravity of the support element and the second contact surface section. In particular, the support element has only one second contact surface section and no contact surface section adjoining the first contact surface section on the opposite side. The flexible material extends, in particular, exclusively in a flat manner on the side or half of the support element facing away from the second contact surface section. This design allows the desired positioning of the center of gravity to be achieved by means of the sectionally curved, i.e., rounded, contact surface, without having to arrange the pivot axis of the support element off-center between the two opposing longitudinal ends of the support element.

[0020] Preferably, an adjusting device is arranged between the longitudinal element and the support element. The adjusting device allows the support element to be adjusted relative to the longitudinal element, in particular at least among other things, preferably exclusively, moved. According to the invention, the support element can be moved in the longitudinal direction relative to the longitudinal element. To avoid friction, the adjusting device is preferably designed such that the movement is not accompanied by a rotation of the support element and / or the adjusting device relative to the longitudinal element. The adjusting device is arranged between the longitudinal element and the support element insofar as it is designed to generate a force acting between the longitudinal element and the support element. In particular, the adjusting device need not be arranged entirely between the longitudinal element and the support element in a spatial sense.

[0021] The adjusting device preferably comprises at least one actuating element that can be driven manually, electrically, pneumatically, and / or hydraulically. The actuating element is preferably arranged axially offset from the support element with respect to the longitudinal center axis on the longitudinal element. The actuating element preferably has an internal adjusting thread that meshes with an external thread, preferably metric and preferably self-locking. The longitudinal element preferably has an external thread. Alternatively, the longitudinal element preferably has no thread. In this case, its cross-sectional area, which is preferably uniform along its length, is preferably not point-symmetric. Preferably, the adjusting device or the actuating element is stationary, integrally formed with the support element, or separate from it. A surface of the support element facing the load-bearing element is preferably point-symmetric or elongated.

[0022] The longitudinal element is designed as a threaded rod, particularly at least in the section over which the support element and / or the adjusting element can move, and preferably over its entire length. The adjusting element is in particular in the form of a nut or a threaded sleeve with a hexagonal outer contour in a cross-section perpendicular to the longitudinal center axis. Preferably, the longitudinal element has a metric 16 mm thread, and the adjusting element can be turned using a wrench with a 24 mm wrench size. Alternatively or additionally, the adjusting element preferably has at least one lever extending outwards from the longitudinal axis. Most preferably, the adjusting element is designed as a wing nut with at least two opposing wings or levers.

[0023] The adjusting device is preferably designed for a releasable positive-locking or friction-locking fixation, in particular clamping, of the longitudinal element. For this purpose, the adjusting device particularly preferably has at least two contact elements that, during operation, bear against the longitudinal element for fixing. For friction-locking fixation, a longitudinally extending surface of the longitudinal element is particularly smooth. For positive-locking fixation, the longitudinal element has, in particular, longitudinally offset features such as teeth. This method of fixing effectively prevents the disadvantages of rotation.

[0024] The adjusting device preferably comprises an adjusting device housing, which in particular includes a first handle. Furthermore, the adjusting device preferably has a first actuating handle mounted on the adjusting device housing so as to be movable, in particular pivotable about a handle pivot axis that is preferably angled or skew to the longitudinal center axis. The adjusting device is preferably designed such that, during operation, movement of the first actuating handle relative to the adjusting device housing causes the support element to be displaced relative to the longitudinal element. Furthermore, the adjusting device is preferably designed such that a subsequent opposite movement or release of the first actuating handle relative to the adjusting device housing during operation does not result in any relative movement between the longitudinal element and the support element or the adjusting device.In this way, the longitudinal element can be gradually moved over a greater distance by means of an alternating movement of the first operating handle, without it unintentionally moving back. The adjusting device is preferably designed in the manner of a clamping clamp, a one-handed clamp, or a glue clamp.

[0025] The adjusting device preferably has an additional operating handle designed such that its movement relative to the adjusting device housing allows the support element to be displaced relative to the longitudinal element in the opposite direction. This allows the longitudinal element to be extended again after being moved over a greater distance (so) and prepared for the next use of the assembly device.

[0026] The first operating handle and / or the subsequent operating handle are connected to a return element, in particular a spring. This returns the operating handle to a starting position from which it can be operated.

[0027] Preferably, the support element extends from the longitudinal center axis in a radial direction that is at least twice as long, preferably at least three times as long, and particularly preferably at least five times as long as the radial extension of the longitudinal element. In particular, the support element surrounds the longitudinal element tangentially and is preferably rotationally symmetrical with respect to the longitudinal center axis. This design ensures reliable support under varying assembly conditions.

[0028] The support element is preferably at least partially, and in particular entirely, made of a plastic, preferably a thermoplastic, and most preferably polyethylene. This makes the support element particularly friction-resistant and ensures minimal wear even during relative movement to elements adjacent to the support element, especially the actuating element.

[0029] In an advantageous embodiment of the invention, the mounting device includes an adjusting element that serves to form a stop for the support element in the first position. The adjusting element is, in particular, spaced further away from the support element than the support element and is arranged on the longitudinal element. The pivot axis of the support element is preferably arranged along the longitudinal direction between the adjusting element and the support element. The adjusting element preferably allows the angle by which the support element is pivoted relative to the second position in the first position to be set, thereby adjusting the pivoting of the support element required for assembly to an optimal degree.

[0030] The adjusting element is mounted so that it is displaceable relative to the longitudinal element, at least partially parallel to the longitudinal center axis. In particular, the adjusting element has an internal adjusting thread that meshes with the external thread of the longitudinal element. This allows the position of the adjusting element to be changed easily and prevents it from being affected by axial forces.

[0031] Preferably, the adjusting element has two adjoining adjusting element sections along its longitudinal center axis. A cross-sectional area of ​​a first adjusting element section, perpendicular to the longitudinal center axis, preferably has a greater width than a cross-sectional area of ​​a second adjusting element section, also perpendicular to the longitudinal center axis. The width of the second adjusting element section corresponds, in particular, at least substantially to the width of the elongated recess of the support element and / or is at least partially inserted into the recess. This design of the adjusting element allows, on the one hand, the swivel angle of the support element to be limited and, on the other hand, prevents unintentional rotation of the adjusting element while the support element is in the first position.

[0032] The problem is further solved by an assembly system. The assembly system comprises an assembly device according to the invention and a holding device. The holding device comprises a holding element extending longitudinally in a longitudinal direction. The holding element has at least one support surface for the support element and at least one holding recess for receiving the longitudinal element. In particular, the holding element has several holding recesses spaced apart from one another in the longitudinal direction of the holding element. The at least one holding recess is, with respect to the longitudinal direction of the holding element, in particular arranged at least substantially or exactly centrally between two ends of the holding element. In the case of several holding recesses, these are preferably of the same type. When using the assembly system, the longitudinal direction of the holding element and the longitudinal direction must be arranged perpendicular to each other.

[0033] The retaining element is, in particular, a flat and / or metallic element whose length is preferably many times greater than its width. The length measured in the longitudinal direction of the retaining element is preferably at least 50 cm, more preferably at least 60 cm, and more preferably exactly 70 cm. Preferably, the thickness is 10 mm and the width is 80 mm. Preferably, the retaining element is a flat bar. This makes the mounting system particularly suitable for installing undermount sinks. For this purpose, the retaining element is positioned on a worktop recess in a worktop, below which the undermount sink is to be fixed, such that the retaining element extends transversely across the worktop recess and its ends rest on the worktop.The longitudinal element is then inserted into the holding recess, the support element is placed on the support surface, and the undermount sink is then lifted as a fixture, as described above, for example by manually turning the adjusting element above the support element.

[0034] The mounting device and the holding device preferably form the mounting system insofar as they are to be used together, but are movable relative to each other and / or detachable from each other. Alternatively, the mounting device and the holding device preferably form a mounting system that is at least not easily separable. Preferably, the longitudinal center axis, in particular the longitudinal element, is arranged in a fixed position relative to the holding element, and optionally the support element and / or the adjusting element is formed integrally with the holding element.

[0035] The retaining element preferably comprises, or is formed from, a hollow profile, particularly one made of aluminum. A hollow profile is any profile that is not a solid profile. The hollow profile utilizes the hollow chamber effect, which results in increased bending stiffness per unit area of ​​material. Preferably, the hollow profile is closed in cross-section, meaning it encloses a cavity. The cross-sectional area of ​​the hollow profile is preferably mirror-symmetrical. This allows for maximum stability. Furthermore, the use of aluminum enables a low weight.

[0036] The retaining element preferably has a cross-sectional extension in a first direction and a second direction perpendicular to it. The retaining recess extends continuously in the first direction. The extension of the retaining element in the first direction is particularly preferably at least as large as the extension of the retaining element in the second direction. This means that, in the application, the retaining element has a height greater than its width. This further increases the relevant bending stiffness per unit area.

[0037] The retaining recess, viewed from above, is preferably at least substantially U- or C-shaped and open to one side of the retaining element. The retaining recess is preferably at least substantially rectangular and / or channel-shaped and extends from one longitudinal side of the retaining element with a limited extent in a direction corresponding to its width. This design of the retaining recess allows the mounting device to be easily detached from the holding fixture and variably repositioned.

[0038] Alternatively, the retaining recess is completely surrounded by the retaining element, in particular the hollow profile, in a top view of the support surface. The retaining recess is preferably designed as an elongated hole. This achieves a particularly secure support for the support element. In this case, the support element preferably has a contact surface that rests against the retaining element during operation and is elongated in the same direction as the elongated hole. This is preferably the longitudinal direction of the retaining element.

[0039] Preferably, the retaining element has at least three retaining recesses spaced apart along its longitudinal direction. A first, particularly central, retaining recess is positioned between a second and a third, and is located closer to the second recess than to the third. A plurality of retaining recesses allows the mounting system to accommodate undermount sinks, particularly double sinks, whose drain openings are positioned differently relative to the countertop cutout, without requiring any changes to the retaining element's position relative to the countertop cutout or any increase in its length.Due to the different distances of the second and third mounting recesses from the first, the mounting system is not only perfectly adapted to three different types of undermount sinks, but to at least five, since the mounting element can also be reversed and thus used in a mirrored position.

[0040] The retaining element preferably has a contact surface opposite the support surface, which is at least partially formed by a flexible material, preferably an elastomer or textile layer, and particularly preferably a felt layer. The material is, in particular, part of the retaining element. The material prevents the retaining element from scratching the worktop.

[0041] Preferably, the longitudinal direction of the holding element is horizontally oriented. Preferably, the holding device comprises a support device arranged on the holding element, with at least one first support element extending at least partially vertically and at least one, preferably at least three, rollers for moving the holding device on a floor. This forms the assembly system into a floor-movable assembly cart. The holding device or the holding element and the support device are preferably fixed in position relative to each other.

[0042] This mounting system design simplifies the installation of washbasins on walls. As previously described, the washbasins can be lifted using the mounting device and the holding device, with the holding device resting directly on the floor via the support device. The mounting system, along with the washbasin, can then be moved towards the wall, and the washbasin, with its horizontally extending openings, slid onto threaded studs that protrude from the wall in the conventional manner.

[0043] The rollers of the support device span a surface on the floor, which is intersected, in particular, by the longitudinal center axis. Preferably, the retaining recesses are located within this surface when viewed vertically. In particular, the support device comprises at least four rollers that span a rectangle. The retaining element is, in at least one configuration of the support device, spaced at least 50 cm away from the rollers, and at least a portion of this space is pivotable, in particular, about a vertical pivot axis.

[0044] The support device preferably comprises at least two support elements, each supporting one side of the retaining element. Alternatively, the support device comprises only one support element, with which the retaining element forms a cantilever, thus making the mounting system more space-saving. Particularly in the case of two support elements, the mounting system preferably has at least one support element extending substantially parallel to the retaining element and positioned between the retaining element and the surface spanned by the rollers. The support element serves to rest the washbasin to be mounted before the mounting device is inserted into the drain opening of the washbasin. The extension of the support element in the longitudinal direction of the retaining element and / or the distance between the support elements is variable, in particular, to allow the mounting system to be adapted to different washbasins and given installation spaces.

[0045] Preferably, the holding device is designed such that the distance between the holding element and the rollers is variably adjustable. In particular, the support device is manually or automatically height-adjustable. This allows for adaptation to different conditions and washbasins. If the distance between the holding element and the rollers is adjustable, height adjustability of the longitudinal element relative to the holding element is not strictly necessary. Therefore, in an alternative preferred embodiment of the invention, the longitudinal element is fixed in position relative to the holding element and, together with the holding element, is height-adjustable for insertion of the support element through the drain opening of the fixture to be installed.

[0046] Preferably, the mounting system allows the item to be clamped between the support element and the holding element. This ensures that the item is fixed in position during installation.

[0047] As an alternative to the mounting system described above, a mounting system can be designed consisting of two individual trestles, which are already used elsewhere in the field of kitchen and sanitary fitting installation, a mounting device, and a holding device. The unloaded trestles are to be positioned at a distance from each other sufficient to allow the fitting to be placed between them. In particular, the fitting is placed on a support element, which in turn rests on the trestles or their crossbars. The support element encloses, in particular, a portion of the trestles, preferably the crossbar, at least partially, preferably in a U-shape, and / or is of variable length. The holding element is to be placed on the trestles above the fitting. The trestles each have, in particular, at least three, and in particular four, casters, which are preferably lockable.

[0049] Where appropriate, functionally equivalent parts should be provided with identical reference numerals.

[0050] The Figs. 1 and 2 Figure 1 shows a first assembly device 2 according to the invention from two perspectives rotated 90° relative to each other. The assembly device 2 comprises a longitudinal element 8 extending lengthwise in a longitudinal direction A. The assembly device also comprises two support elements 10 arranged on the longitudinal element 8. The support element 10 is pivotably mounted on the longitudinal element 8 about a support element pivot axis 22. The support element 10 is shown from a first position (see Figure 1). Fig. 1 and5 ) into a second position (see Figs. 6 to 9 The longitudinal element 8 is transferable, wherein the support element 10 extends substantially perpendicularly to a longitudinal center axis 12 in the second position, whereas in the first position it extends at an angle of approximately 20° to the longitudinal center axis 12. A support element 14 is arranged on the longitudinal element 8 at a distance in the longitudinal direction A from the support element 10. The support element 14 is mounted so as to be displaceable relative to the longitudinal element 8 in the longitudinal direction 12. The longitudinal element 8 is designed as a threaded rod with an external thread 16. The support element 14 is designed as a round disc with a central recess through which the longitudinal element 8 extends. The radius of the support element 14 is more than three times the radius of the longitudinal element 8. The support element 14 is made of polyethylene.

[0051] Adjoining the support element 14, the mounting device 2 has an adjusting element 18 which has a recess with an internal adjusting thread that meshes with the external thread 16 of the longitudinal element 8. The adjusting element 18 forms a metric hexagon on the outside, so that the support element 14 can be moved in the longitudinal direction A by turning the adjusting element 18 using a standard wrench.

[0052] The support element 10 has a center of gravity S, which is spaced away from both the support element pivot axis 22 and the longitudinal center axis 12 (see Fig. 1 ), whereby the supporting element 10, in the absence of external forces and an arrangement of the longitudinal element 8 according to Fig. 1 automatically arranges itself in the first position. The support element 10 is elongated. InIn the second position, its extension in a first direction B perpendicular to the support element pivot axis 22 is at least twice as large as its extension in a second direction C parallel to the support element pivot axis 22 (see Fig. 10 The support element 10 has an elongated recess 24 extending in the first direction B. The recess 24 is an elongated hole that is penetrated by the longitudinal element 8.

[0053] The support element has a contact surface 26 on its upper side, which temporarily rests against the fixture 4 when the mounting device 2 is used. The contact surface 26 is fully covered by a felt layer. In its second position, the contact surface 26 has a flat first contact surface section 26a extending perpendicular to the longitudinal center axis 12 and a flat second contact surface section 26b extending parallel to the longitudinal center axis 12. Between the first contact surface section 26a and the second contact surface section 26b, the contact surface 26 has a curved surface section that creates a smooth transition between the contact surface sections 26a and 26b.

[0054] The mounting device 2 further comprises an adjusting element 28 for forming a stop for the support element 10 in the first position. The adjusting element 28 is arranged on the longitudinal element 8 at a greater distance from the support element 14 than the support element 10. The adjusting element 28 has an internal adjusting thread that meshes with the external thread 16 of the longitudinal element 8, by means of which the position of the adjusting element 28 along the longitudinal axis 12 can be varied. The adjusting element 28 has two adjoining adjusting element sections 28a, 28b. A cross-sectional area of ​​a first adjusting element section 28a, perpendicular to the longitudinal center axis 12, has a greater width than a cross-sectional area of ​​a second adjusting element section 28b, also perpendicular to the longitudinal center axis 12. In the first position of the support element 10, the second adjusting element section 28b is partially inserted, particularly in its recess 24.

[0055] The Fig. 6 and7 Figure 1 shows a first assembly system 30 according to the invention, comprising the assembly device 2 described above and a holding device 32, which here consists of a holding element 34. The structure of the holding element 34 is defined by the Figs. 3 and 4 The retaining element 34 extends elongated in a longitudinal direction D and has a width that is significantly less than its length but significantly greater than its thickness. The retaining element 34 has a support surface 36 and an opposing contact surface 44. Furthermore, the retaining element 34 has three retaining recesses 38, 40, 42, which are spaced apart from each other in the longitudinal direction D. A central first retaining recess 40 is spaced closer to a second retaining recess 38 than to a third retaining recess 42. The recesses are arranged according to Fig. 4 Each is U-shaped.

[0056] The Figs. 5 to 7The application of the first mounting system according to the invention is illustrated. First, the mounting device with the support element is guided from above through a drain opening 5 of an undermount sink 4 to be installed. The undermount sink 4 rests below a worktop recess 64 of a worktop 62 on two schematically depicted, exemplary support elements 60. After the support element 10 has been completely guided through the drain opening 5, it is moved from the first position into the position shown in Fig. 6The second position shown is pivoted. For this, the support element 10 slides with its contact surface along an underside of the undermount sink 4, whereby the undermount sink 4 initially makes contact with the second contact surface section 26b and slides along the contact surface 26 until it reaches the first contact surface section 26a. Meanwhile, the retaining element is positioned centrally above the worktop cutout 64 and rests with its contact surface 44 on the edges of the worktop 62. Since the drain opening 5 is to remain centrally located below the worktop cutout 64, the longitudinal element 8 is guided into the first retaining recess and the support element 14 is placed on the support surface 16 of the retaining element 34.To then lift the undermount sink 4, the adjusting element 18 is to be turned using a wrench and thereby the longitudinal element 8 with the support element 10 and the undermount sink 4 resting on it is moved relative to the support element 14, to the retaining element 34 and to the worktop 62 into the position shown. Fig. 7 to raise the indicated position.

[0057] The Fig. 8 and 9 Figure 1 shows another assembly system according to the invention with a different holding device 32. The holding device 32 shown here has, in addition to the holding element 34, a support device 46 with two substantially vertically extending support elements 48 and four rollers 50 for moving the holding device 32 on a base 52. The [unclear text] Fig. 8 and 9The mounting system 30 shown is used for mounting washbasins, particularly in bathrooms. The holding device 32 is to be positioned above the washbasin 6 to be mounted, and the washbasin 6 is to be lifted relative to the holding device 32 using the mounting device 2 (see above). The washbasin 6 is then to be slid onto mounting pins 56 projecting from a wall 54, and the mounting pins 56 are to be guided through recesses 58 in the washbasin 6.

[0058] Fig. 10 shows an alternative mounting device 2, whose adjusting element 28, actuating element 18 and support element 14 are the same as in the mounting device 2 according to the Figs. 1 and 2 are formed. The supporting element 10 is indeed like the one in the Figs. 1 and 2 The supporting element 10 shown is mounted, but has a further bore 25 in addition to the recess 24, in particular opposite the contact surface section 26b.

[0059] Fig. 11Figure 1 shows cutaway crossbars 66 of two different trestles, forming an alternative mounting system 30 (not shown in its entirety). A support element 68, extending mainly transversely, is arranged on the crossbars 66 for placing the furniture item 4, 6 (not shown) to be mounted. From the given perspective, the support element 68 surrounds the crossbars 66 in a U-shape and is variable in length to ensure reliable placement of the furniture item even with different distances between the trestles.

[0060] The Figs. 12 and 13Figure 1 shows another assembly system 30. This system includes an adjusting device designed to clamp the longitudinal element 8, which has a rectangular cross-section, as part of the assembly device 2. The adjusting device comprises an adjusting device housing 70, which is formed integrally with the support element 14. The adjusting device has a fixed handle 72 and a first actuating handle 74 pivotably arranged on the adjusting device housing 70. The adjusting device is designed such that pivoting the first actuating handle 74 relative to the adjusting device housing 70 causes a displacement of the support element 14 relative to the longitudinal element 8 in its longitudinal direction A. Furthermore, the adjusting device is designed such that, when the first actuating handle 74 pivots back or comes to a standstill, at least a displacement against the longitudinal direction A is prevented.This applies as long as a second actuating handle 76 of the positioning device is not actuated. Actuating this handle allows either displacement of the support element 14 relative to the longitudinal element 8 against the longitudinal direction A or free displacement.

[0061] The retaining element 34 is formed from a hollow aluminum profile. The height of the retaining element 34 corresponds to its width. The retaining element 34 has a concealed, elongated retaining recess through which the longitudinal element 8 extends, on which the support element 10 is pivotably mounted.
