Abstract
Description
[0001] The invention relates to a dice with interchangeable sides, in particular a modular dice for use in, for example, board games, role-playing games or educational games.
[0002] Standard dice have six non-interchangeable sides and are therefore only suitable to a limited extent for different game scenarios or didactic content, as adaptation is only possible by replacing the entire die.
[0003] Dice with interchangeable faces are known from the prior art, where the faces are typically attached using mechanical connectors, such as plug-in connections. Such fastening solutions require additional space within the cube, resulting in larger overall dimensions. This negatively impacts handling and ergonomics, and in particular makes it more difficult to throw multiple dice simultaneously.
[0004] Furthermore, existing designs have drawbacks when it comes to replacing the cube faces themselves. In particular, the plug-in connections often require considerable force to release. Cube systems constructed from individual tiles also necessitate the assembly of several separate components, requiring a central section to be combined with multiple small tiles; this also applies to versions with magnetic tiles. Due to the small size of these tiles, their handling is limited, reducing ease of assembly and resulting in an overall unpleasant and sometimes frustrating building experience.
[0005] The invention therefore addresses the problem of providing a dice in which the sides can be easily and intuitively replaced without increased force or assembly effort, yet which can be assembled into a stable cube and ensures comfortable handling for the user.
[0006] This problem is solved by the features listed in the claims.
[0007] According to claim 6, the game cube consists of six independent, identical side parts that can be combined without additional auxiliary components. According to claim 1, the side parts are designed such that each side part, in conjunction with five other side parts, forms a stable cube.
[0008] Due to the magnets arranged on the inner surfaces 2, 3, 4 and 5 according to claim 1, the side pieces align themselves automatically when assembled and hold adjacent side pieces securely together, so that the cube formed from six side pieces remains stable when rolled. At the same time, the magnetic connection allows the side pieces to be easily separated again if necessary.
[0009] As described in claim 4, joining the side parts causes a protrusion 6 of an inner side to engage positively in a recess 7 of an adjacent inner side, thereby further increasing the stability of the assembled cube and preventing unwanted slippage of the side parts.
[0010] The features listed in claim 2 make the outer surface 1 of the respective side part suitable for receiving symbols, numbers, colors or other representations in order to enable different game scenarios or learning content.
[0011] Due to the features described in claim 5, the composite cube has a rounding 8 on its edges, which improves the feel and the rolling behavior of the cube.
[0012] The invention allows the cube faces to be changed easily, quickly, and without increased assembly effort. At the same time, it creates a stable, easy-to-handle game cube that is flexible for various applications and allows for user-friendly, intuitive assembly.
[0013] An example implementation will be shown using the Fig. 1 to 3 explained. Fig. Figures 1a to 1d show a side panel in orthogonal views. Fig. Figure 2 shows the side panel in an isometric view. Fig. Figure 3 shows the game cube, composed of six side parts, in an isometric view, with symbols arranged on the outer surfaces 1 as an example.
