Abstract

The utility model relates to means for mass entertainment and can be used in probabilistic games using dice, lotto, for drawing lots in sports competitions, etc.

The proposed useful model of a magnetic dice is designed to obtain a random value of the result of a “throw”, previously applied to the surface of the body (“drum”).

The housing (or housings, if there are several of them) is fixed on an axis, between two posts. The posts are fixed at the base and have an arrow protrusion at the top. Also, permanent magnets are installed inside each housing and in the base under the housing. On the outer edges of each case there is a marking of the values of the “throw” result, protected from abrasion by a transparent membrane.

The player spins the “drum” (makes a “throw” of the dice) and waits a few seconds until, under the influence of friction forces and magnetic fields, the “drum” stops and the protrusion-arrow indicates the result.

Description

The utility model relates to means for mass entertainment and can be used in probabilistic games using dice, lotto, for drawing lots in sports competitions, etc.

The proposed useful model of a magnetic dice is designed to obtain a random value of the result of a “throw”, previously applied to the surface of the case.

It is worth noting that the term BODY, in this description, abstract and formula of the utility model, denotes a volumetric body as part of the structure of a magnetic dice, located on the axis between the posts, containing one or more bearings, permanent magnets, and images of the values of the result of the “throw” on surfaces. The surface of the body, in addition to the outer edge (or edges, if there are several), also has at least two side edges. It is also worth noting that the outer edge (or edges) of the body is the edge located between the two side edges of the body, and is located in direct line of sight in relation to the players. Among all the structural elements, it is the body that is driven by the player.

The procedure of rotating the body of a magnetic dice around the axis on which it is located (in order to obtain a result), for better understanding and brevity, is called "throwing" the dice. Also, the term body, for better understanding, has been replaced in places in the text with the word “drum”.

The known magnetic dice is a single structure containing a base, stands with a protrusion-arrow holding the axis on which the body or bodies are placed, if there are several of them, as well as permanent magnets located in each body, base and/or in other structural elements .

The principle of operation of both the existing versions of the magnetic dice and the proposed utility model is that the player spins the body of the “drum” (makes a “throw” of the dice) and waits a few seconds until, under the influence of friction forces, as well as magnetic fields The “drum” will stop and the arrow protrusion will indicate the result.

There is a well-known dice, described in the video presentation “I made strange DICE!”, posted on the website of the master Veniamin “Lefty” dated March 3, 2021:

The disadvantage of the prototype magnetic dice is that the marking of the values of the result of the “throw” is inextricably linked with the entire product, and it is the marking area that contacts the player’s finger or palm, first of all being subject to rubbing, until it is impossible to determine the result. In this case, the side edges of the body are not marked with the values of the “throw” result.

A magnetic dice is known, described in an application for a utility model, registration No. 2023116620 dated June 23, 2023.

The disadvantage of a magnetic dice is that in one of the options, the marking of the values of the result of the “throw” is inextricably linked with the entire product, and in another option, replaceable or permanent inserts are used, and in all options, it is the marking area that is in contact with the finger or the palm of the player, first of all being subjected to mashing, until it is impossible to determine the result. In this case, the side edges of the body are not marked with the values of the “throw” result.

The technical problem that the proposed utility model is aimed at achieving is to eliminate the design disadvantage of magnetic dice, in which the area for marking the values of the “throw” result is erased and the operating time of the product is reduced.

The proposed utility model is illustrated by the following drawings:

In fig. 1 shows a general view of a variant of the proposed magnetic dice with two hexagonal bodies and protective membranes. There is a symbolic marking on the side edge of the case closest to the stand.

In fig. 2 shows an isometric view of the section along A-A of Fig. 4.

In fig. 3 is a frontal view of FIG. 1.

In fig. 4 is a left view of FIG. 3.

In fig. 5 shows the extension element “B” of Fig. 6, showing a special groove, a protective membrane (1) and a protected surface with markings (8).

In fig. 6 shows a cross-section along B-B of Fig. 3.

Where: 1 – protective membrane; 2 – stand; 3 – body of the body; 4 – axis;

5 – bearing; 6 – permanent magnet; 7 – base;

8 – insert or surface of the body with markings.

The technical result is achieved by the fact that on top of the “throw” result values located on the outer edge of each case, protective membranes made of transparent, elastic, abrasion-resistant, non-magnetic material (polyethylene terephthalate, polycarbonate, acrylic, etc.) are installed in special grooves. and also, on the side edge of the body closest to the rack, the values of the “throw” result are marked with a numerical or alphabetic or symbolic marking or color marking or a combination of the listed options.

These design improvements prevent the marking of the “throw” result values from abrading, significantly extending the life of the product. At the same time, the use of various types of markings applied to the side edge of the case closest to the rack significantly increases the variability of the “throw” result, expanding the scope of application of the product.

In addition, the image of the value of the “throw” result, applied to the side edge of the case closest to the rack, can be made with raised markings, as well as in Braille, which will increase the information content, including for people with disabilities.

The manufacture and assembly of the proposed magnetic dice is carried out as follows. First, based on the future area of application, the number of bodies, the number of faces on the bodies, the type of marking and the type of result values are determined. After the number of housings and their dimensions have become known, the inter-hull gap is selected and the axle length is calculated by adding the width of each housing and the inter-hull gap, and also taking into account the length of the ends of the axle entering the racks, if necessary. The height of the housings and the length of the axis determine the dimensions of the racks and base. Then select the material from which the listed structural elements will be made. The following non-magnetic materials can be used: wood, plywood, plastic, cured epoxy resin, etc., as well as combinations thereof. After this, the base, housings, axles and struts are manufactured using hard machining, stamping, casting, 3D printing, or other methods.

Next, the product is assembled. Each housing contains a bearing (for example, a steel rolling bearing) and permanent magnets (for example, ferrite or neodymium). The magnets are then installed in the base and/or other structural elements. After this, the housings are distributed on the axis. The axle is fixed in the racks, and the racks are attached to the base. After this, on the outer edge of each case, in special grooves, over the values of the “throw” result, protective membranes are installed from a transparent, elastic, abrasion-resistant, non-magnetic material (for example, polyethylene terephthalate, polycarbonate, acrylic, etc.).

Initially flat protective membranes are held in special grooves due to elastic deformation (bending), and, as the surface wears out (loss of transparency), without the use of tools or special skills, they are easily replaced with new ones. In addition to the main function, the protective membrane, due to elastic deformation, is capable of pressing and keeping thin inserts marked with the value of the “throw” result, such as paper inserts, from accidentally flying out.
