But if a new kitchen range of a different, especially smaller, size needs to be replaced for reasons such as malfunction, the new kitchen range may not match the original mounting holes.

Disclosure of Invention

It is an object of embodiments of the present application to provide an auxiliary device for auxiliary mounting of a hob, such that the hob can be firmly mounted to an improperly sized mounting hole by means of the auxiliary device.

According to a first aspect of the present application, embodiments of the present application provide an auxiliary device for auxiliary mounting of a hob, said auxiliary device comprising an auxiliary unit comprising:

a clamping portion configured to clamp an upper and lower mesa region of a cooktop adjacent to a mounting hole for mounting the cooktop;

and an expansion part configured to expand inward with respect to an inner sidewall of the mounting hole at least in a state where the auxiliary unit is clamped to the hob by the clamping part, so as to hold the hob.

Thus, the auxiliary unit is fixed to the hob by the clamping part, and the hob can be supported on the expansion part of the auxiliary unit. In this way, the cooktop can be mounted to mounting holes that would otherwise be unsuitable. The term "holding part" is understood here to mean, in particular, a holding part which is fixed relative to the hob on the basis of an upper and a lower hob region holding the hob. By "inwardly extending relative to the inner side wall of the mounting hole" is understood, in particular, that the inner side wall lying at the boundary of the mounting hole extends towards the inside of the mounting hole, or that, in the operating state, the expansion fills the recess formed by the mounting hole, at least as seen in projection in the vertical direction.

According to an alternative embodiment of the present application, the clamping portion comprises a first portion corresponding to the lower mesa region, a second portion corresponding to the upper mesa region, and a third portion connected between the first portion and the second portion.

According to an alternative embodiment of the present application, the auxiliary device comprises at least two auxiliary units independent of each other. A more stable support is provided by the plurality of auxiliary units.

According to an alternative embodiment of the present application, the clamping portion is substantially U-shaped in cross section. Thereby simplifying the shaping of the grip.

The clamping part can be more firmly fixed on the cooking bench through the screws.

According to an alternative embodiment of the present application, the second portion at least partially forms the expansion. This results in a simple structure of the auxiliary unit.

According to an alternative embodiment of the present application, the first threaded holes comprise at least two first threaded holes adapted to form different pitches to corresponding inner side walls of the mounting hole; and/or the second threaded holes comprise at least two second threaded holes adapted to form different spacings to corresponding inner side walls of the mounting hole. Therefore, the device can adapt to mounting holes with different sizes.

According to an alternative embodiment of the application, the first threaded holes comprise at least two sets of first threaded holes spaced apart from each other in the longitudinal direction of the auxiliary unit, each set of first threaded holes being provided with at least one first screw; and/or the second threaded holes comprise at least two sets of second threaded holes spaced apart from each other in the longitudinal direction of the auxiliary unit, each set of second threaded holes being provided with at least one second screw. Thereby allowing the clamping portion to be more firmly fixed to the cooktop by clamping at least two points.

According to an alternative embodiment of the present application, each set of first threaded holes comprises at least two rows of first threaded holes, the arrangement lines of which are oriented perpendicular to the corresponding inner side walls of the mounting holes and are spaced apart from each other in a direction parallel to the inner side walls, respectively, in a state in which the auxiliary unit is clamped to the cooktop by the clamping part, and which are staggered with each other in a direction perpendicular to the inner side walls; and/or each group of second screw holes comprises at least two rows of second screw holes, the arrangement lines of the at least two rows of second screw holes are respectively oriented perpendicular to the corresponding inner side wall of the mounting hole and are spaced apart from each other in a direction parallel to the inner side wall in a state that the auxiliary unit is clamped to the cooking bench by the clamping part, and the at least two rows of second screw holes are staggered with each other in a direction perpendicular to the inner side wall. Thereby enabling a more accurate selection of the optimal clamping position.

According to an alternative embodiment of the application, the first part is configured to be elastically pivotable relative to the third part for clamping in the lower table top area; and/or the second portion is configured to be resiliently pivotable relative to the third portion to clamp against the upper deck area. Thereby simplifying the structure of the clamping portion and simplifying the clamping operation.

According to an alternative embodiment of the application, the auxiliary unit is provided with an orientation mechanism adapted to orient the third portion parallel to the corresponding inner side wall of the mounting hole.

According to an alternative embodiment of the application, the orientation means comprise an abutment surface provided at the clamping portion perpendicular to the third portion for abutment against another inner side wall of the mounting hole adjacent to the inner side wall corresponding to the third portion. It is thereby ensured by a simple construction that the third portion of the clamping portion is parallel to the corresponding inner side wall of the hob.

According to an alternative embodiment of the present application, the orientation means comprise a first orientation surface adapted to abut against the third portion and a second orientation surface adapted to abut against the corresponding inner side wall, the first orientation surface being parallel to the second orientation surface; the orientation mechanism comprises an adjustment structure by which the spacing between the first orientation surface and the second orientation surface can be adjusted. This ensures that the third portion of the holding part is spaced apart from the inner side wall by a desired distance, with the third portion being parallel to the corresponding inner side wall of the hob.

According to an alternative embodiment of the present application, the adjustment structure comprises a parallelogram structure, four sides of which are pivotally connected to each other, and a locking part adapted to selectively lock or unlock the relative pivotability between adjacent sides of the parallelogram, the first and second orientation surfaces being provided on opposite sides of the parallelogram structure.

Detailed Description

In order to make the technical problems, technical solutions and advantageous technical effects to be solved by the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and a plurality of exemplary embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the present application.

Fig. 1 schematically shows an example of a hob 4 in a perspective view. The cooking bench 4 is provided with mounting holes 40 for mounting a cooking appliance 7, in particular a gas cooker. The mounting hole 40 is generally square and has four inner side walls 43. The size of the mounting holes 40 is generally matched to the size of the cooktop 7 that it was originally intended to fit into. But if, for reasons such as malfunctions, it is required to replace with a new hob 7 of a different, in particular smaller, size, the new hob 7 may not match the original mounting holes 40.

In order to solve this problem, the present application proposes an auxiliary device for auxiliary installation of the hob 7.

Fig. 2 schematically shows in a partial view one example of a mounting hole 40 of a hob 7 mounted to a hob 4 by means of an auxiliary unit 1 of the auxiliary device of the present application.

As shown in fig. 2, the auxiliary unit 1 includes:

a clamping part 2, the clamping part 2 being configured to clamp an upper table top area 42 and a lower table top area 41 of the hob 4 adjacent to the mounting holes 40 for mounting the hob 7;

the expansion part 3, the expansion part 3 is configured to expand inward with respect to the inner sidewall 43 of the mounting hole 40 at least in a state where the auxiliary unit 1 is clamped to the hob 4 by the clamping part 2, to hold the hob 7.

Thereby, the auxiliary unit 1 is fixed to the hob 4 by means of the clamping part 2, whereas the hob 7, in particular the flange of the bottom shell of the hob 7, can be supported on the expansion part 3 of the auxiliary unit 1. In this way, the cooktop 7 can be mounted to mounting holes 40 that would otherwise be unsuitable.

Fig. 3 schematically shows an example of the auxiliary unit 1 of fig. 2 in a perspective view.

According to an exemplary embodiment, as shown in fig. 2 and 3, the clamping part 2 comprises a first portion 21 corresponding to a lower mesa region 41, a second portion 22 corresponding to an upper mesa region 42, and a third portion 23 connected between the first portion 21 and the second portion 22.

According to an exemplary embodiment, as shown in fig. 2 and 3, the clamping portion 2 is substantially U-shaped in cross section. Thus, three portions of the clip portion 2 can be easily formed from the plate material by bending the plate material.

According to an exemplary embodiment, as shown in fig. 2 and 3, the second portion 22 forms at least partially the expansion 3. This results in a simple structure of the auxiliary unit 1. It is also conceivable, as shown in fig. 4, that the expansion 3 also comprises an expansion area 30 which does not belong to the clamping part 2. The expansion region 30 extends, for example, from the third portion 23 of the clamping part 2 in a direction away from the second portion 22.

According to an exemplary embodiment, as shown in fig. 2 and 3, the first portion 21 has a first threaded hole 210, for which first threaded hole 210 a corresponding first screw 211 is provided, which first screw 211 can be brought against the lower mesa region 41 by screwing the first screw 211 relative to the first threaded hole 210. The clamping part 2 can be more firmly fixed to the hob 4 by means of screws.

According to an exemplary embodiment, as shown in fig. 3, the first threaded holes 210 include at least two first threaded holes 210, the at least two first threaded holes 210 being adapted to form different spacings to the corresponding inner side walls 43 of the mounting hole 40. Thereby accommodating different sized mounting holes 40.

According to an exemplary embodiment, as shown in fig. 3, the first threaded holes 210 comprise at least two sets of first threaded holes 210 spaced apart from each other in the longitudinal direction 5 of the auxiliary unit 1, each set of first threaded holes 210 being provided with at least one first screw 211. Thereby allowing the clamping part 2 to be more firmly fixed to the hob 4 by clamping at least two points. In fig. 3, two sets 212 of first threaded holes 210 are outlined in dashed boxes. These two groups 212 are located, in particular, on both sides of the intermediate plane 8 of the auxiliary unit 1 perpendicular to the longitudinal direction 5 and are sufficiently far apart in the longitudinal direction 5. The distance between the two groups 212 in the longitudinal direction 5 (the distance between the centers) is in particular more than one third, in particular more than one half, of the longitudinal length of the clamping part 2. Each set 212 may include at least one first threaded bore 210.

According to an exemplary embodiment, as shown in fig. 3, each set of first screw holes 210 includes at least two rows of first screw holes 210, arrangement lines 213 of the at least two rows of first screw holes 210 are oriented perpendicular to corresponding inner side walls 43 of the mounting holes 40 and spaced apart from each other in a direction parallel to the inner side walls 43, respectively, in a state in which the auxiliary unit 1 is clamped to the hob 4 by the clamping part 2, and the at least two rows of first screw holes 210 are staggered with each other in a direction perpendicular to the inner side walls 43. Thereby enabling a more accurate selection of the optimal clamping position. In fig. 3, two alignment lines 213 of two rows of first screw holes 210 of one group are exemplarily shown in two solid lines.

In addition to or instead of providing threaded holes in the first portion 21 of the clamping part 2, it is also conceivable to provide threaded holes in the second portion 22 of the clamping part 2. A corresponding second screw is likewise provided for the second threaded hole, which can be brought to bear against the upper mesa region 42 by screwing the second screw relative to the second threaded hole.

Similar to the first threaded bore 210, the second threaded bore may include at least two second threaded bores adapted to form different spacings to the corresponding inner side walls 43 of the mounting bore 40. The second threaded holes may comprise at least two sets of second threaded holes spaced apart from each other in the longitudinal direction 5 of the auxiliary unit 1, each set of second threaded holes being provided with at least one second screw. Each set of second screw holes may include at least two rows of second screw holes, the arrangement lines 213 of which are oriented perpendicular to the corresponding inner side walls 43 of the mounting holes 40 and spaced apart from each other in a direction parallel to the inner side walls 43, respectively, and which are staggered from each other in a direction perpendicular to the inner side walls 43 in a state in which the auxiliary unit 1 is clamped to the hob 4 by the clamping part 2.

It is also conceivable, contrary to the above, to provide fixedly on the first portion 21 and/or the second portion 22 of the clamping part 2 a threaded post which corresponds to the lower table-top area 41 and/or the upper table-top area 42, respectively, and to provide on the threaded post a sleeve which can be screwed relatively, which can be brought into abutment against the lower table-top area 41 and/or the upper table-top area 42, respectively, by screwing the sleeve.

Fig. 5 schematically shows an example of the mounting of the hob 7 to the mounting holes 40 by means of the auxiliary unit 1 in a bottom view.

According to an exemplary embodiment, as shown in fig. 5, the auxiliary device comprises at least two auxiliary units 1 independent of each other. In fig. 5, six auxiliary units 1 are exemplarily shown, but only two of the auxiliary units 1 are labeled. These auxiliary units 1 are symmetrically clamped on the cooktop 4, whereby the cooktop 7 can be firmly mounted. Obviously, the number of auxiliary units 1 and the clamping positions on the hob 4 can also be chosen differently from fig. 5. In the extreme case it is also possible that the auxiliary device comprises only one auxiliary unit 1.

In the embodiment of fig. 2 to 5, the clamping part 2 or the auxiliary unit 1 can be rigid, since it can already be adjusted by means of screws. Alternatively thereto, it is conceivable that the first portion 21 is configured to be elastically pivotable with respect to the third portion 23 to clamp in the lower table area 41; and/or the second portion 22 is configured to resiliently pivot relative to the third portion 23 to clamp the upper mesa region 42.

Referring to fig. 2, when clamping the auxiliary unit 1 to the cooktop 4, it is desirable that the third portion 23 of the clamping portion 2 of the auxiliary unit 1 is parallel to the corresponding inner side wall 43 of the cooktop 4. For this purpose, the auxiliary unit 1 may be provided with an orientation mechanism 6 (see fig. 6 to 9), the orientation mechanism 6 being adapted to orient the third portion 23 parallel to the corresponding inner side wall 43 of the mounting hole 40.

Fig. 6 schematically shows another example of the auxiliary unit 1 in a perspective view. In this embodiment, the auxiliary unit 1 has an orientation mechanism 6.

According to an exemplary embodiment, as shown in fig. 6, the orientation means 6 comprise an abutment surface 60 provided on the clamping portion 2 perpendicular to the third portion 23, the abutment surface 60 being intended to abut against another inner side wall 43 of the mounting hole 40 adjacent to the inner side wall 43 corresponding to the third portion 23. It is thereby ensured by a simple construction that the third portion 23 of the clamping part 2 is parallel to the corresponding inner side wall 43 of the hob 4. In this case, the auxiliary unit 1 shown in fig. 6 can be mounted, in particular, in the upper right corner of the mounting opening 40 shown in fig. 1, while the contact surface 60 contacts the inner side wall 43, which is marked with reference number 43.

According to an exemplary embodiment, referring to fig. 2 and 7 to 9, the orientation means 6 comprise a first orientation surface 61 adapted to abut against the third portion 23 and a second orientation surface 62 adapted to abut against the corresponding inner side wall 43, the first orientation surface 61 being parallel to the second orientation surface 62; the orientation mechanism 6 comprises an adjustment structure 63, by means of which adjustment structure 63 the distance between the first orientation surface 61 and the second orientation surface 62 can be adjusted. This ensures that the third portion 23 of the holding part 2 is spaced apart from the inner side walls 43 by a desired distance, with the third portion 23 being parallel to the corresponding inner side walls 43 of the hob 4.

Fig. 7 schematically shows a second example of the orientation mechanism 6.

According to an exemplary embodiment, as shown in fig. 7, the adjustment structure 63 comprises a parallelogram structure 65 and a locking part 66, the four sides of the parallelogram structure 65 being pivotally interconnected with respect to each other, the locking part 66 being adapted to selectively lock or unlock the relative pivotability between adjacent sides of the parallelogram, the first orientation surface 61 and the second orientation surface 62 being provided on opposite sides of the parallelogram structure 65. By means of the parallelogram 65, the first orientation surface 61 and the second orientation surface 62 are always parallel to each other, but the distance between them is changed when the angle α between the two sides is changed. After being adjusted to the proper spacing, it can be locked by the locking portion 66. When clamping the auxiliary unit 1 on the hob 4, the locked orientation mechanism 6 is placed between the third portion 23 of the auxiliary unit 1 and the corresponding inner side wall 43 of the mounting hole 40. After the clamping is completed, for example after the screw has been tightened, the locking portion 66 can be released again, so that the orientation mechanism 6 can be removed again.

Fig. 8 schematically shows a third example of the orientation mechanism 6.

Fig. 9 schematically shows a fourth example of the orientation mechanism 6.

According to an exemplary embodiment, adjustment structure 63 includes a telescoping portion 64, telescoping portion 64 including a base 641 and a telescoping member 642 telescoping relative to base 641. Telescoping member 642 may be threadably coupled to base 641 as shown in FIG. 8. Alternatively, the expansion element 642 may be fixed to the base 641 by a locking pin 643 as shown in fig. 9. Here, the base 64 has, for example, a through hole 644 into which the bayonet 643 is inserted, and the expansion element 642 has a groove 645 into which the bayonet is inserted. The first orientation surface 61 and the second orientation surface 62 may then be provided to the base 641 and the expansion element 642, respectively. The distance between the first and second orientation surfaces 61, 62 can thereby be conveniently adjusted to a desired distance, ensuring that the desired distance is met between the third portion 23 of the clamping portion 2 and the corresponding inner side wall 43 of the mounting hole 40. After the clamping is completed, the orientation mechanism 6 can likewise be released from between the third portion 23 of the clamping portion 2 and the inner side wall 43 of the mounting hole 40 by adjustment and removed.
