Description

Fixing device

Technical Field

The invention relates to a fastening device for fastening a rinsing component to be inserted into a cutout of a carrier plate, which rinsing component is arranged with a retaining edge on the carrier plate, comprising a retaining body, a fastening section for engaging the carrier plate from below, and a threaded element by means of which the fastening section can be moved relative to the retaining body for clamping relative to the carrier plate, the retaining body having a connecting section for fastening to the rinsing component.

Background

Such a fastening device serves to fasten a rinsing element, for example a kitchen sink, to the carrier plate. The carrier plate, for example a wooden or plastic or stone plate, has a corresponding cutout which corresponds to the geometry of the rinsing element to be inserted, but is slightly smaller, so that the rinsing element can rest with a circumferential edge on this cutout edge of the carrier arm. For this purpose, the flushing member has, in addition to the actual, sunken sink section, an edge section which forms a retaining edge, wherein the flushing member can have not only a sunken sink region but also a flat or slightly obliquely running water trap or drip region or a second sink region or the like which can be connected to the sink region. The flushing member can be made of metal or plastic, and the design variants are diverse in terms of geometry and material.

In order to fix the inserted rinsing element on the carrier plate, a plurality of fixing devices of this type can be used. Each fastening device has a retaining body, on which a connecting section is arranged in a laterally projecting manner, which connecting section, for example, is inserted into a corresponding recess on the flushing component and is clamped there during assembly, or which connecting section is fastened to the flushing component by means of a thread, for example, in an expansion sleeve there. Furthermore, a fastening section is provided which projects almost to the side opposite the connecting section and engages the carrier plate from below in the assembled position, i.e. rests against the underside of the plate. The fastening section, which is usually a metallic clamping arm or the like, is penetrated in the recess by a threaded element, i.e. a fastening screw, which is screwed into a corresponding internally threaded section on the retaining body. By screwing in, the fastening section which bears against the screw head is moved in the direction of the retaining body and is fastened relative to the underside of the carrier plate.

The carrier plates that can be used have different thicknesses, typically 20mm, 30mm and 40mm thick. Depending on the plate thickness, it is necessary to use bolts and metal clamping arms of different lengths, since the retaining body is fixed to the flushing component and is finally bridged over the remaining bearing plate thickness by the screw length or the clamping arms. For example, a 30mm or 40mm thick plate can be fixed with a fixing device, and in order to fix on a plate that is only 20mm thick, another fixing device with shorter screws or different clamping arms should be used. Although a certain balance can be achieved by screwing the threaded element into the internal thread to a different extent, when the screwing-in is too small, strength problems arise in the screw connection, so that the fixing is inadequate, or the screw and the clamping arm protrude too far, so that it stands on the underlying device, for example a dishwasher, or the device cannot be pushed in, so that it is not possible to lengthen the screwed-in part.

Disclosure of Invention

It is therefore an object of the present invention to provide a relatively improved fastening device.

In order to solve this problem, according to the invention, in a fastening device of the type mentioned at the outset, the holding body comprises a first body part having a connecting section and a second body part having a fastening section and a screw element, wherein the two body parts can be connected to one another in a form-fitting manner in different positions.

In the fixing device according to the invention, the retaining body is of two parts and comprises a first and a second body part. The first body part has a connecting section by means of which the first body part is fixed to the flushing member. The second component, on the other hand, has a fastening section which engages the carrier plate from below and a threaded element for axially tensioning the fastening section. Now, according to the invention, the two body parts can be positively connected in different positions, but can be detachably connected to one another, i.e. the two parts can be fixed in different relative positions to one another. This allows the length or height of the holding body consisting of the two body parts to be variable and to be adapted to the given situation, i.e. the thickness of the carrier plate. Since the threaded element is arranged on the second body part together with the fastening section, a tensioning of the fastening section relative to the second body part is finally achieved, so that, despite the different bearing plate thicknesses, a similar state is finally always obtained in all fastening variants, i.e. irrespective of the plate thickness, the threaded fastening/screw fastening is always almost identical or at least similar. No very different degrees of screwing in etc. are required. Since the body parts are fixed to one another in precisely the respective different positions, the differences in the thickness of the carrier plate are compensated for by correspondingly changing the length or height of the retaining body.

The possibility for different carrier plate thicknesses is thereby given by the separate fixing means, since the fixing means can have an integrated height or thickness compensation to a certain extent by the body parts being fixable to one another in different relative positions. Furthermore, it is ensured that, since the actual screwing operation is carried out exclusively within the second body part, the clamping operation is always carried out analogously irrespective of the thickness of the carrier plate, i.e. a similar fastening state results.

In order to fix the two body parts in a simple manner in different positions in a form-fitting manner with respect to one another, the two body parts can be inserted into one another in different positions, preferably in a form-fitting manner. This enables a corresponding geometry of the bodies arranged by insertion to be achieved in a simple manner. For this purpose, the first body part can have at least one recess into which the second body part can be inserted in different positions. It is conceivable here to provide only one recess, which is configured to provide a different, defined plug-in position for the second body part. However, it is also conceivable to provide a plurality of individual plug-in positions (for example in the form of plug-in holes or plug-in grooves) on the first body part, which define the respective positions.

A particularly advantageous development of the invention with individual recesses on the first body part provides that the recesses are delimited by inner walls lying opposite one another, wherein a plurality of first projections which project into the recesses and are spaced apart from one another and are formed between the grooves are provided on each inner wall, and the second body part is delimited by outer walls lying opposite one another, wherein at least one second projection projects on each outer wall, wherein the second projections can be pushed into the grooves between the first projections. In other words, a corresponding groove arrangement is formed on the first and second body parts, which achieves that both body parts can be pushed into the groove with a corresponding projection. Accordingly, corresponding teeth are provided on the inner and outer walls, which teeth can be pushed into each other. At least two grooves are provided on the inner wall, but it is of course also possible to provide a plurality of grooves if desired, and at least two projections on the outer wall. Since the two grooves are positioned offset from one another on the first body part, a correspondingly different height positioning is achieved by the two second projections provided on the second body part being pushed into one groove pair or the other. There are of course also more possibilities for variation if a plurality of corresponding grooves are provided on the first body part.

Expediently, a plurality of second projections are provided on each outer wall, that is to say a plurality of joining planes are always present, so that the fixing of the body parts to one another is more robust. For example, it is conceivable to provide three or four grooves on the inner and outer wall, respectively, which grooves are spaced apart from one another by a few millimeters, respectively, so that a correspondingly thin grid is provided, which allows an exact adjustment. The recess in the first body part preferably extends over the entire height or length of the first body part, so that the second body part projecting from the first body part can ultimately be positioned arbitrarily.

According to a first variant of the invention, it can be provided that the threaded element has an external thread which engages in an internal thread formed in the bore of the fastening section, wherein the threaded element can be rotated in the second body part but is received in a positionally fixed manner in the second body part, and the fastening section is moved along the threaded element when the threaded element is screwed. The threaded element, which is arranged in an axially positionally fixed manner on the second body part but is mounted so as to be rotatable relative to the body part, forms a spindle to the extent that the fastening section of the nut is displaceable on the spindle. For this purpose, the threaded element, which is preferably designed as a metal bolt, has an external thread which engages into an internal thread in the bore of the fastening section. If the threaded element is screwed, the external thread is screwed into the internal thread, wherein the fixing section, as a result of being axially displaceable, is displaced along the axially immovable threaded element and is therefore tensioned relative to the carrier plate.

According to a second inventive variant, an internal thread section can be provided on the second body part, into which a threaded element coupled to the fastening section can be screwed. As described, the screw fastening is carried out only in the second body part, for which purpose, in this variant, a corresponding internal thread section is provided, into which a screw or a bolt is screwed. The fastening section is coupled to a screw or a bolt, for which purpose the fastening section has a corresponding hole or opening through which the threaded element passes, wherein the fastening section bears against the threaded element and is thereby entrained when screwed in.

Preferably, for forming the internal thread section, a sleeve-like member is used, which is inserted into a recess provided on the body part. The sleeve-like member is provided with an internally threaded hole into which a screw is screwed. The sleeve-like component is fixed in the recess and is therefore inserted into the recess in a positionally fixed manner, so that the component is axially supported when screwed in and the fixing section can thus be axially tensioned. For this purpose, the sleeve-like component has, for example, at one end, a respective lateral widening which engages into the respective lateral recess widening, so that the widening lies on a shoulder of the recess widening.

As described, not only the threaded element according to the first inventive variant, but also the sleeve-like member according to the second inventive variant is axially fixed, i.e. cannot move axially in the second body part. For axially fixing the respective component, the recess preferably has a recess enlargement, into which the threaded element or the sleeve-like component engages with an end-side enlargement. By means of this form-fitting engagement, the threaded element or the sleeve-like component is axially fixed in a simple manner in the recess, which can be fixed by simple pressing or snapping in. The threaded elements or sleeve-like members can be received with the other end in a recess in the second body part so as to be movably fixed to each other and nevertheless accessible for rotation by a tool.

A further problem in the known fastening device is that the screw head of the fastening screw, under which the fastening section is supported, protrudes a few millimeters below the carrier plate, which is achieved in that the fastening section protrudes almost horizontally from the fastening screw. Such an excess can lead to problems when the flushing member, i.e. the carrier plate, is to be pushed, for example, into the region in which the fastening device is located (for example, into the dishwasher), since it interferes with the screw head when pushed in from below.

In this case, to assist in this, a suitable development of the invention provides that the fastening section projects laterally from the second body part and merges via a fold into a section which engages the operating plate from below. The actual connection region of the fastening section to the threaded element is therefore not located in the plane of the underside of the carrier plate, but rather is located almost in the second body part. In other words, the screw element does not project beyond the second body part, as little as the corresponding region of the fastening section that is fastened to the second body part. The fastening section extends by a fold in the direction of the free end of the second body part and then merges into the actual section of the lower contact plate. In the assembled position, the section of the fastening section which is arranged directly below the work plate is thus the furthest downwardly projecting part, wherein this section is sufficiently close to the underside so that no problems arise when pushing in a dishwasher or the like. That is, the fixing device according to the present invention is also low and there is no difficulty in installing the built-in device.

In particular, the fastening section is preferably formed as a double bend, i.e. it has a first leg arranged on the threaded element and projecting laterally from the body, a second leg bent almost 90 ° and extending parallel to the body, and a third leg which merges into the section joining from below.

For inserting the flushing member, it is particularly advantageous if the securing section can be rotated by at least 90 ° relative to the second body part. During assembly, one or more fastening devices with corresponding connecting sections are first inserted into the component-side recess, i.e. fastened to the flushing component. Now, if the fastening section projects rigidly to the side, insertion into the plate cutout can only be achieved with great difficulty or even not, since the fastening section can interfere with the carrier plate. To assist in this case, the or each fastening section can be rotated by at least 90 ° relative to the body. That is, the securing section is rotated into an insertion position in which it does not protrude laterally, so that the irrigation member can be inserted. When the retaining edge of the flushing member is located on the carrier plate, the respective securing section is then swung out, so that the section engaging from below is located below the carrier plate and can be fastened.

For this purpose, two stops are expediently provided on the main body part, which limit the pivoting movement, so that a defined positioning of the fastening section is achieved. The second body part can have a ramp, which abuts against the stop and on which the fastening section slides during pivoting. In this connection, the securing section can be rotated into the retaining position either automatically when screwing the threaded elements coupled by the threaded connection, or alternatively, this can also be done in a guided manner by manual pivoting.

Preferably, the two body parts themselves are made of plastic, which enables simple manufacture at very low cost.

Conversely, the fixing section, the threaded element or the sleeve-like member is made of metal.

In addition to the fastening device itself, the invention also relates to an assembly comprising a work plate, a flushing member and a plurality of fastening devices of the type described above which are fastened to the flushing member by means of a connecting section and which fasten the flushing member to the work plate by means of the fastening section. The flushing member may be any flushing member made of metal or plastic or composite material or the like, and likewise the working plate may be constructed of different materials and with different plate thicknesses.

Detailed Description

Fig. 1 shows a fastening device 1 according to the invention, which is suitable for fastening a rinsing element to be inserted into a cutout of a carrier plate, which rinsing element is arranged on the carrier plate with a retaining edge. The fixing device 1 has a holding body 2 which comprises a first body part 3 and a second body part 4, which are preferably made of plastic. The two

body parts

3, 4, which will be explained below, can be fixed to each other in different positions.

An elongate connecting section 5 with corresponding latching projections 6, which are inserted into and latched in corresponding recesses fixed on the flushing member, as will be explained below, is provided, i.e. molded, on the first body part 3.

On the one hand, a fastening section 7 in the form of a hook claw is provided on the second body part 4, which fastening section engages on the underside from below the carrier plate into which the rinsing member is inserted and serves to clamp the rinsing member relative to the carrier plate. Furthermore, a threaded element 8 is provided on the second body part 4, which acts on the fastening section 7, i.e. the fastening section is supported on the threaded element 8, so that the fastening section can be moved in the axial direction relative to the second body part 4.

The two

body parts

3, 4 can be connected to each other in a form-fitting manner in different positions. To achieve this, the first body part 3 has a corresponding recess 9 extending over the height or length of the body part 3, the second body part 4 being inserted into the recess 9. Each inner wall 10 of the first body part 3, which laterally delimits the recess 9 opposite to one another, has a plurality of projections 11 which project into the recess 9, the projections 11 defining respective slots 12 between them. The protrusion 11 and the groove 12 are elongated.

The second body part 4 has outwardly projecting projections 14 on its mutually opposite outer walls 13, which projections likewise define corresponding grooves 15 therebetween. The projections 14 and the slots 15 are also elongated.

As shown in fig. 1, corresponding tooth profiles are thus formed on the inner wall 10 and the outer wall 13. The tooth profiles can now be inserted into one another in a form-fitting manner, wherein, because the projections and the grooves are at the same distance from one another, the second body part 4 can be inserted into the first body part 3 in different positions, so that in this way the overall height of the retaining body 2 can be varied in a simple manner. Due to the correspondingly form-fitting engagement, a secure fixing of the two body parts to one another is ensured.

In the exemplary embodiment shown, the fastening section 7 is of Z-shaped design, i.e., is multiply bent. The fastening section has a first side 16, with which the fastening section is supported below a head 17 of the threaded element 8. A second side 18 extends from the first side 16 (the first side 16 extends laterally from the second body part 4), the second side 18 extending substantially parallel to the second body part 4. The second body part merges via a fold into a third side 19, which in the mounted position is located below the carrier plate and is clamped with the end-side claw section 20 below the carrier plate.

In order to achieve a tensioning and thus an axial movement of the fastening section 7 relative to the second body part 4 and thus also relative to the first body part 3 and thus finally relative to the flushing component, a sleeve-like component 21 is provided, which is received in a recess 22 of the second body part and engages with an end-side widening 23 into a recess widening 24 and is fixed axially in a form-fitting manner therein. The sleeve-like component 21 has an internally threaded bore, not shown in detail, into which the threaded element 8, which is embodied here as a socket head cap screw and has a corresponding engagement opening 25 for a tool, is screwed with a corresponding thread section. During the screwing-in operation, the fastening section 7 is forced along and moves axially to some extent into the second body part 4, since the fastening section 7 is supported with the lateral edge 16 below the screw head 17. If the connecting section 5 is fixed and the fixing section 7 is located with the side 19 below the carrier plate, then this side 19 must now be brought against the underside of the plate and thus tensioned.

Fig. 2 and 3 show a second embodiment of the fastening device 1 according to the invention. In terms of construction, it corresponds to the fastening device according to fig. 1, and therefore the same reference numerals are used for the same components. The fastening device is likewise suitable for fastening a rinsing element to be inserted into a cutout of the carrier plate, which rinsing element is arranged on the carrier plate with the retaining edge. The design of the holding body 2 corresponds exactly to the embodiment of fig. 1, so that reference is essentially made to the embodiments here. Only the screw element 8 and its mechanical connection to the fastening section 7 are different here.

The fastening device 1 has a holding body 2, the holding body 2 being composed of a first body part 3 and a second body part 4 which are fastened to one another, wherein the first body part and the second body part are preferably made of plastic. For fastening to the flushing component, a connecting section 5 with a clamping projection 6 is also provided here by way of example, wherein, as already explained, forms other than clamping fastening, for example by means of screws or the like, are also conceivable.

In this case, the two

body parts

3, 4 can also be fixed to one another in different positions, for which purpose, just as in the embodiment according to fig. 1, tooth sections which can be pushed into one another are provided on the two body parts. For this purpose, a recess 9 is provided on the first body part 3, into which recess 9 the second body part is pushed, which has a projection 11 and a groove 12 provided on the inner wall 10 projecting into the recess, and a projection 14 and a groove 15 provided on the outer wall 13 on the second body part 4. The insertion together in different positions to vary the body height is therefore also achieved here by means of the grid.

As in the first exemplary embodiment, the fastening section 7 is also bent in a Z-shape, the fastening section 7 having a first side 16, a second side 18 extending parallel to the second body part, and a third side 19 having a claw section 20. Here, too, the fastening section 7 passes through the recess 22, so that the fastening section can be moved longitudinally in the recess 22.

Here, the one-piece threaded element 8, which is received in the recess 22 of the second body part 4 and is axially fixed with its end-side widening 23 in the recess widening 24, but is rotatable about its longitudinal axis, is also used for tensioning the fastening device 1. However, in this alternative, the coupling of the securing section 7 with the threaded element 8 and thus the movement thereof is different.

The threaded element 8 is embodied as a screw having an engagement opening 25 for a tool, here for example for the upper side of a hexagon socket wrench, and having an external thread 37 on its outer side. The fastening section 7 has a bore provided with an internal thread 38, wherein the threaded element 8 passes through the bore and thus screws the internal thread onto the external thread. Since the screw element 8 is axially fixed in position and can only be rotated, the fastening section is moved axially by the screw connection when screwing the screw element 8, wherein the fastening section is guided laterally in the recess 22. Thus, depending on the direction of rotation, the securing section 7 moves along the threaded element 8 in one direction or the other. In a simple manner, the tensioning is thereby achieved with only two elements, namely the threaded element 8 and the fastening section 7 and the constructed threaded coupling.

Due to the screw connection, the fastening section 7 is also automatically moved from a position pivoted out to the side (shown in fig. 4 below) into a fastening position defined by the stop during the screwing-on process, wherein the fastening section is guided along the inclined surface 39 on the second body part 4 (see fig. 2).

Fig. 4 shows a principle view of fastening the fastening device 1 according to the invention, in the same way as the embodiment shown here only in part on the underside 26 of the flushing member 27. Furthermore, the flushing member has a trough-shaped recess 28. The recess 28 is formed on a projection 30 having a bevel 29. The connecting section 5 is inserted into the recess 28 with a form fit, i.e. with a clamping fit.

The rear side 31 of the first body part 3, which is likewise beveled, rests on the bevel 29, i.e. is supported in a planar manner on the bevel 29.

It can be seen that in the arrangement shown in fig. 4, in which the second body part 4 is fixed in a different position than in fig. 1 on the first body part 3, the second body part projects significantly more, so that the entire body part 2 is therefore longer, i.e. higher, than in the embodiment according to fig. 1 or 2.

Fig. 4 shows the fixation device 1 in the inserted position, i.e. when the rinsing member 27 is inserted into the cutout of the carrier plate. For this purpose, the fixing section 7 is arranged so as to be pivotable relative to the retaining body 2, so that the fixing section is pivotable about the threaded element. The fastening section is in this case in the insertion position and in this insertion position is pivoted out laterally by approximately 90 °. This is achieved in that a corresponding recess 32 is provided on the second body part 4, so that the fastening section 7 can be swiveled into the recess 32 when the threaded element 8 has not yet been screwed on. After the flushing member 27 has been inserted into the cutout of the carrier plate, the fastening section 7 is pivoted out, which in the embodiment according to fig. 2 can also be carried out automatically when the screw element 8 is screwed down, so that the fastening section is brought into the extended position shown in fig. 1 or 2, so that when the screw element 8 is screwed in, the fastening section 7 is pushed into the second body part 4 in this position almost, i.e. the fastening section is moved within the recess 22 formed in the second body part 4, until the fastening section is in the final clamped position. Preferably, the swing-out movement is again limited by a stop, which is achieved in a simple manner by the walls of the second body part 4 that define the recess 22.

Fig. 5 to 7 show different application examples of the fastening device 1 according to the invention, with which the rinsing element 27 is fastened to the carrier plate 33 by means of the fastening device 1. The carrier plate 33 has a corresponding cutout 34, into which cutout 34 the rinsing member 27 is inserted. The rinsing element 27 overlaps the edge of the carrier plate 33, i.e. is supported there, with the retaining edge 35.

It can be seen that the fastening device 1 is fastened with the connecting section 5 in the recess 28 on the sink side. The fastening section 7 is swung out and engages the underside 36 of the carrier plate 33 from below, i.e. is clamped against the underside. It can be seen that at this time the thin plate thickness of 20mm, the second body part 4 is inserted relatively far into the first body part 3, so that the overall height of the retaining body 2 is relatively low. The Z-shape of the fastening section 7 can also be seen very well, the actual connection area of the fastening section to the threaded element 8 being located almost in the interior of the second body part 4.

Fig. 6 shows a similar assembly, wherein the carrier plate 33 here has a thickness of 30mm, for example. It can be seen that the second body part 4 is here arranged to protrude more from the first body part 3, that is to say that the corresponding tooth is inserted into another position. The fixing section 7 again engages the underside 36 of the carrier plate from below. For the tensioning, however, the fastening section does not have to be screwed into the second body part to the same extent as in the exemplary embodiment according to fig. 5, since the second body part 4 is received relatively deeply in the first body part 3 due to the fine grid of the tooth sections.

Finally, fig. 7 shows an arrangement with a carrier plate 33 with a thickness of 40 mm. It can be seen here that the second body part 4 projects distally from the first body part 3, in an arrangement similar to that in fig. 2. The fastening section 7 again engages the underside 36 of the carrier plate from below, wherein the fastening is also ensured.

As fig. 5 to 7 show, the fastening device 1 is only formed at the edge of the carrier plate 33 below the underside 36, i.e. the fastening device 1 only does not project significantly beyond the underside 36. This enables a simple movement of, for example, a dishwasher from below into the region without interfering with the fastening device 1.
