Description

[0031] The invention is now further explained with reference to an embodiment, which is diagrammatically depicted in the drawings.

[0032] FIG. 1 shows the top of the support strip I according to the invention with the elevated support surfaces 12 and the profile 13.

[0033] FIG. 2 shows the bottom with the mirror-inverted profile 13′.

[0034] FIG. 3 shows four support strips 1 that are stacked on top of one another for elevation or storage.

[0035] FIG. 4 shows the trapezoidal cross-section 11 with the mirror-inverted profiles 13 and 13′.

[0036] FIGS. 5a-5d show another embodiment of a support strip according to the invention.

[0037] The support strip 1 has a rectangular shape and a trapezoidal cross-section 11. The support strip 1 is cast of silicone, in one piece without joints and crevices, which ensures slip resistance, temperature resistance, chemical resistance, and food safety. Dirt does not gain a foothold, and it is easy to clean by hand.

[0038] The damping behavior can be varied by stacking the support strip 1.

[0039] On the top of the support strip 1, there are two elevated support surfaces 12, with a raised profile 13 in each case.

[0040] The profile 13 is designed in the form of projections that are concentric, open on the side edges, or circular or spiral in shape.

[0041] The bottom of the support strip 1 is provided with a mirror-inverted profile 13′. This profile 13′ is designed in the form of grooves that are concentric, open on the side edges, or circular or spiral in shape. During stacking of multiple support strips 1, the mirror-inverted profiles 13, 13′ engage in one another. This results in a stable stacking during elevation of the cutting board by stacking the support strips on top of one another as well as in a variation of the damping behavior.

[0042] In the case of two applied support strips 1, the two elevated support surfaces 12 provide four support surfaces on which a curved cutting board, with a downward curvature, can also be applied and used. The cutting board does not lie around wet for hours but rather is ventilated.

[0043] The profiles 13 on the top and the mirror-inverted profiles 13′ on the bottom improve the adhesion in the case of wet conditions and make possible stable stacking.

[0044] A material thickness of at least five millimeters produces sufficient clearance height for quick and easy lifting of the cutting board.

[0045] The Shore hardness of the silicone further ensures sufficient stiffness for secure placement in the washer.

[0046] Because of the trapezoidal cross-section 11 and the Shore hardness of the silicone, the support strip 1 is stiff enough to use the support strip 1 even for wiping processes. To this end, the support strip 1 is picked up lengthwise at the top edge between thumb and forefinger and, e.g., scraps/wetness are removed from the table. In addition, hard blows/noises on the support material are damped by the support strip 1.

[0047] FIG. 3 shows a diagrammatic depiction of a system that consists of four support strips 1, 1′, 1″, 1′″ that are stacked on top of one another. The profiles on the bottoms in this case engage respectively in the profiles on the tops of the subjacent support strips, so that the four support strips are snugly connected. The support strips 1, 1′, 1″, 1′″ can be distinguished in their damping and in their thickness so that a user can select a desired working height and the desired damping property (hard, medium, soft) by selecting the stacked support strips.

[0048] FIG. 4 shows a cross-section through a support strip I with a trapezoidal cross-section 11. The profile 13 on the top is mirror-inverted to the profile 13′ on the bottom, so that the projections on the top can be brought into a snug connection with corresponding grooves on the bottom. The longitudinal side 14 forms an angle of approximately 70° on the bottom.

[0049] In addition, in the depicted embodiment, both the longitudinal edges in the area of the top and the longitudinal edges in the area of the bottom have curved edges, by which the occurrence of fractures or cracks on the edges, which would facilitate the settling of germs, is avoided.

[0050] FIGS. 5a-5d show another embodiment of the support strip according to the invention. FIG. 5a shows a view of the bottom, FIG. 5b shows a view of the side, FIG. 5c shows a view of the top, and FIG. 5d shows a sectional view. The raised profile and the recessed profile are designed as mirror-inverted spirals in this embodiment.
