Description

[0001] The invention relates to trivets for hot cookware with a base body.

[0002] Trivets for placing hot pots and pans are known in numerous designs and are typically made of materials such as cork, silicone, metal, or glass. Despite the variety of materials, these trivets share a fundamental problem: they always have only one fixed, unchangeable shape and size. This means they are only suitable for certain diameters or geometries and are often insufficient for larger cookware. In practical use, it becomes clear that many trivets are too small for large or heavy pots, pans, or roasters, so the vessels only partially rest on the trivet or their hot bases protrude beyond its edge. This leads to instability, inadequate weight distribution, and an increased risk of tipping or slipping.Furthermore, the worktop or table surface can be directly subjected to thermal stress or damage by protruding, hot areas.

[0003] Adapting to different pot sizes or shapes is not possible with existing trivets, as their dimensions are completely predetermined by their design. A small trivet is functionally inadequate in many situations, while a large trivet, although more practical, takes up a disproportionate amount of storage space and is unwieldy in everyday use. A flexible system that can adapt to different vessel sizes and usage situations is not currently known. Overall, existing solutions therefore do not offer a sufficient way to provide a variably adaptable, safe, and large-area surface for a wide variety of hot vessels.

[0004] Against this background, the technical challenge is to provide a trivet that is not limited to a single fixed shape or size, but can be variably adapted to different pot and pan diameters. The trivet should offer a sufficiently large, stable, and secure surface to fully accommodate both small and large or heavy cookware, reliably preventing hot parts from slipping or protruding. At the same time, the trivet should allow for space-saving storage, be easy to handle, and adapt flexibly to different usage and kitchen situations.

[0005] The problem is solved by means of a coaster according to claim 1, in particular its characterizing features, in which the base body is formed of two support plates which are arranged to one another by means of at least one fastening means and are held removable from one another by means of a connecting element.

[0006] The use of two support plates, held together by a fastener, allows for a stable yet easily detachable connection. The connecting element allows the plates to be moved and, if necessary, pulled apart. This enables compact storage and flexible size adjustment of the trivet to fit various containers. The circular shape ensures even contact with round cooking pots.

[0007] The design allows the individual support plates, when pushed together, to form a round, corner, star, trapezoid, heart, cuboid, and / or oval shape. This makes the trivet adaptable to various pot shapes, aesthetically pleasing, and particularly suitable for use at different events.

[0008] The idea is that at least one magnet is located at the center of the circular base, holding the support plates together in a closed circular shape. A centrally positioned magnet ensures uniform attraction between both support plates, resulting in a stable and symmetrical closed circular form. This increases the mechanical strength when closed and improves the aesthetic appearance.

[0009] Furthermore, the fastening device is intended to be a magnet or a hinge.

[0010] Furthermore, it is planned that the connecting element will be a rail element.

[0011] A key advantage is the use of two magnets for the detachable connection of the carrier plates. Using two magnets distributes the holding force across two points, increasing stability and preventing the plates from twisting against each other. Furthermore, the connection can be released more easily and precisely.

[0012] Furthermore, the rail element is designed to form an outer boundary of at least one support plate. If the rail element simultaneously functions as an outer boundary, the number of components is reduced, and the component serves a dual function as a guide element. This increases the simplicity of the design and operational reliability when moving the plates.

[0013] Furthermore, it is advantageous that the rail element is designed in such a way that the coaster can be hung up using the rail element when collapsed. The ability to hang the coaster in its compact state allows for particularly space-saving storage – for example, on hook rails in the kitchen. This significantly increases its practical everyday use.

[0014] Furthermore, the design incorporates two support plates, each with a top and bottom surface. The symmetrical construction with two usable sides allows for reversible use and reduces wear. The user can use the coaster on either side without having to pay attention to specific orientations.

[0015] It is also conceivable that the upper surface is ribbed to achieve an anti-slip effect and / or the lower surface is smooth. The ribbing creates an anti-slip effect, thus securing the placed cookware more effectively. The smooth underside ensures gentle contact with furniture and also facilitates cleaning.

[0016] A particular advantage is that both surfaces of the support plates can be used for holding cookware. This double-sided usability allows for more flexible use of the trivet, regardless of its orientation. Even if one side shows signs of wear, its functionality remains fully intact.

[0017] The plan is for the support panels to be made of wood. Wood as a material offers good thermal insulation, is durable, environmentally friendly, and visually appealing. It also reduces the risk of scratches on sensitive surfaces.

[0018] It is conceivable that the connecting element is made of stainless steel. Stainless steel offers high strength, corrosion resistance, and an elegant appearance. It ensures stable rail guidance even with frequent use and exposure to moisture.

[0019] Ultimately, the connecting element is intended to be held to the underside of one of the support plates by means of a flat rivet. A flat rivet allows for a secure and flush attachment of the rail element to the support plate. The flat design prevents the coaster from wobbling and increases user comfort.

[0020] Further advantages of the invention will become apparent from the following drawings: Fig. 1: A perspective view of the assembled coaster in its closed state, Fig. 2: A perspective view of the coaster in its open state with the support plates spaced apart, Fig. 3: an exploded view of the coaster, Fig. 4: A top view of the coaster in the closed state with the section line AA marked, Fig. 5: A view from below of the coaster in its closed state, Fig. 6: A section view according to section line n AA from Fig. 4 of the coaster in the closed position, Fig. 7: A top view of the coaster in the open state, Fig. 8: Underside view of the opened support plates of the coaster.

[0021] Fig. Figure 1 shows the coaster in a perspective view in its closed state, which is referred to below as reference numeral 10. The coaster 10 has a base body G, which consists of two semicircular support plates 11 and 12 that together form a circular shape. In this position, the support plates 11 and 12 are held together by fasteners M, for example, magnetic fasteners, preferably at least one first central magnet 15. A connecting element V in the form of a rail element 20 is provided between the two support plates, which allows linear guidance of the support plates 11 and 12 relative to each other. In this embodiment, the upper surfaces 13 of the support plates 11 and 12 are grooved to provide an anti-slip function. In this closed configuration, the coaster can be stored in a space-saving manner or hung up, for example, using the rail element 20.

[0022] In Fig. Figure 2 shows the coaster 10 in its open state. The support plates 11 and 12 have been shifted in opposite directions along the rail element 20, so that a gap between them becomes visible.

[0023] Fig. Figure 3 shows an exploded view of the components of the coaster 10. The two support plates 11 and 12 can be seen, each with a bore B for receiving the magnets 15. The rail element 20 is provided as a guide element between the support plates 11, 12 and is preferably attached to the lower surface of the support plate 11 by means of a flat button rivet 21.

[0024] In Fig. Figure 4 shows a top view of the coaster 10 in the closed position. The two support plates 11 and 12 are fully joined. The section line AA is drawn and serves as a reference for the sectional view according to Fig. 6.

[0025] Fig. Figure 5 shows the underside of the coaster 10 in the closed position. The rail element 20 is clearly visible attached to the lower surface 14 and simultaneously forms an outer guide over which the support plates 11, 12 can be moved relative to each other when open.

[0026] Fig. Figure 6 shows a cross-section along line AA. Fig. 4. In this illustration, the two support plates 11 and 12 can be seen with their respective upper surfaces 13 and their lower surfaces 14.

[0027] Between the support plates 11, 12 is the first central magnet 15, which, in conjunction with the second magnet 16, holds the two support plates 11, 12 in the closed position against each other. The rail element 20 is attached to the lower surface 14 of the support plate 11 by means of a flat button rivet 21.

[0028] In Fig. Figure 7 shows a top view of the opened base 10. The two support plates 11, 12 are pulled apart along the rail element 20.

[0029] Fig. Figure 8 shows a bottom view of the opened coaster 10. The position and length of the rail element 20 are clearly visible. This extends along the lower surfaces 14 of both support plates 11, 12 and enables linear guidance when pulling them apart.

[0030] The following explains how the coaster 10 works. In practical use, the coaster 10 is initially stored in its compact, closed form – for example, suspended from the rail element 20 or in a drawer.

[0031] To use the trivet, grasp it and manually pull the two support plates 11, 12 apart along the rail element 20, provided the hot cookware is larger than the diameter of the collapsed trivet 10. This movement opens the round base G, releasing the magnets 15, 16 from their holding function. In the open position, a larger, segmented surface is created, suitable for securely holding pots or pans of varying sizes. After use, the trivet 10 can be returned to its compact round shape by simply sliding the support plates 11, 12 together, with the magnets 15, 16 securely centering and holding the support plates 11, 12 in position.
