Best mode of Carrying out the Invention

A toy in accordance with the present invention as shown in Figure 2 has two plates 1 and 2 which are arranged on the same axis 3 and string- biased by a spring 4. The outer surface of the plates has arcs 5, reinforcing ribs 6, stepping openings 7 and a central projection 8 with the openings 9 and 10. The inner surface of the plate 2 has a ring-shaped passage 11 with stepping openings 12 and depressions 13 for fixation of a relative turning of the plates.

The inner surface of the arcs 5 have a transverse slots 14 or transverse projections 15 as shown in Figure 17, 18, 33, 36. Common sides of the arcs 5 and the inner surface of the plates 1 and 2 have radii 16 or chamfers as shown in Figures 2, 17 and 18.

The inner surface of the plate 1 , instead of the ring-shaped passage 11 has a ring-shaped projection 17, and instead of the depression 13 has spherical projections 18 shown in Figures 15, 16, 33. The height of the ring-shaped projection 17 is greater than that of the spherical projection 18. The axis 3 has a head 19 at one end , and at the other end has a collar 20 formed with an inclination from a small diameter at the base of the axis 3 to the greater diameter at the center of the axis. The axis 3 has at least one transverse slot 21 . The slot 21 imports to the axis 3 springy or elastic property and is necessary for a fast assembly of the plate of the toy which makes the toy assembly less expensive and reduces its costs, as can be seen from Figures 2, 13. The central assembly of the toy as shown in Figures 2 and 3, has, in addition to the axis 3, a spring 22, two washers 23 and two plugs 24 with formations 25. The formations 25 provide optimal conditions for pressing of the plugs 24 in the opening 9 and pressing them out. The spring 22 is located between the head 19 on the axis 3 and the washer 23 on the outer surface of one of the plates 1 or 2, The other washer 23 is located on the outer surface of the other plate 2 or 1 and the collar 20 of the axis 19. The inserts 26 with marks of color 27, symbols or reliefs are located in the opening 7 and the outer surface of the plates 1 and 2. The arcs 5 of the plates 1 and 2 are separated by slots 28. Logical elements 29 as shown in Figures 1 , 2, 3, 4, 5 are located in the slots 28.

The radii 16 provided on the arcs 15 are important since they influence the displacement of the plates 1 and 2. When there is no radii, the probability of stopping of the plates 1 and 2 during turning is increased. This can be explained by the fact that the logical element 29 during jiggles and free play, being located on the plates 1 and 2 have a possibility of abutting against the surfaces of the arcs 5 and to stop the neighboring plate 2 or 1. If instead of the sides the radius 16 is formed, the stopping is prevented since the logical elements 29 will slide along the radii 16.

The logical element 29 can be formed as a part of the cylinder, for example %, 1/4, 1/6th etc. Collars 30 are provided at both sides of the logical element as shown in Figures 39B, 40A, 40B, 41 which are formed independently from the outer shape of the logical element as a part of the cylinder. The front surfaces of the logical element are provided from both sides with a radius 31 shown in Figures 40A, 40B, 41 , 42. The radii 31 can be replaced by chamfers. The surfaces of the collars 30 at the base are rounded from both sides, since they have radii 32 shown in Figure 40A, 40B, 41 , 42, The radii 32 can be replaced with chamfers.

The surfaces which are formed by section of the cylinder, or (main surfaces of the logical element) are rounded from both sides by radii 33, and are rounded by radii 34 shown in Figures 39A-40C, 41 -43. Both the radii 31 and 32 and the radii 33 and 34 can be replaced with the chamfers as shown in Figure 17 (hidden lines for radius 34 for example), However, the use of the radii instead of the chamfers is advantageous, since this makes the displacement of the logical elements in the toy smoother without jumps and stops.

A relief 35 formed by a number of marks or lines can be provided by the outer surfaces of the logical element as shown in Figures 39A, 40A, 40B, 40C, 40D , 41 , 42, 43. They can be used both for the logical ordered location of the elements between themselves during playing with the toy, for example to arrange the elements in the order I, II, III, Ml, and for playing by touching for example by blind users. The collars 30 or at least one collar from at least one side of the logical element, have fixators of positional elements formed as projections 36 or depressions 37 shown in Figures 33B, 41 , 43. The logical element can have a front slot formed as a rectangle 38 shown as Figure 42. The base of the slot 38 which is located below the upper point of the collar can serve as a fixator of location of the logical element as shown in Figure 42. The base of the slot 38 can be provided with at least one setting opening 39 shown in Figure 42. The front slot 38 can be formed as any shaped slot, open and not closed, at the apex of the logical element.

The front slot 38 makes possible to use the inserts 40 shown in Figure 42 which are provided for broadening of functional and playing possibilities of the logical element. The inserts 40 as shown in Figure 42 and 44 have setting projections 41 which make possible pressing of the inserts into the openings 39 located at the base of the slot 38 as shown in Figure 42. The inserts 40 can be provided with massaging projections 42 for action on narrow points of fingers during displacement of the logical elements as shown in Figures 42, 44. The inserts and the logical elements can be provided with a release 35, drawings 43 or numbers 44 as shown in Figures 24, 25, 26, 27. They diversify the toy, develop logical thinking, spacial imagination, sensitivity of fingers, etc.

As explained above, the toy uses two plates, namely the plate 1 which is a male plate with a ring-shaped projection 17 and a spherical projection 18 shown in Figure 31 -33, and a plate 2 which is a female plate with a ring- shaped passage 11 , setting openings 12 and depressions 13 as shown in Figures 34-36. It is possible to use in the toy two plates 2 which are female plates, but with the inserts 45 as shown in Figures 30A, 30B. This makes possible to reduce the cost of the toy due to reduction of the number of molds. In order to maintain the functional properties of the toy, one of the plates 2 which is a female plate must be converted into the plate 1 which is a male plate. For this purpose, an insert 45 is used which has the shape of a ring-shaped passage 11 and depressions 13 of the plate 2 which is a female plate) with spherical projections 46 and setting projections 47 shown in Figures 38A-38C. The insert 45 is pressed into the setting openings 12 by the setting projections 47. The plate 2 which is a female plate together with the pressed-in insert 45 is converted into an exact copy of the plate 1 which is a male plate, as shown in Figures 29, 30A, 30B. The plates 1 and 2 can be formed as disks shown in Figures 1 -12, 23, 24, 26, 27, 29, 30A-37, and also as a square shown in Figure 25 or a triangle shown in Figure 28. The shape of the plate in this common case can be formed as any polygon. The reinforcing ribs 6 on the outer surfaces of the plates 1 and 2 impart them additional rigidity as shown in Figure 1 . They are desirable but not absolutely necessary.

The depression 13 interacting correspondingly with the spherical projections 18 on the inner surfaces of the plates 1 and 2 must be located at the most rigid spot of the plate, for example between the axis 3 of the toy and the groups of the toy logical elements 29 at a distance close to the axis 3 of the toy as shown in Figure 36. This provides for a more accurate and clear fixation of a relative displacement of the plates 1 and 2, since the location of the fixing elements at the closed distance to the axis excludes a possible non-parallel location and non-plane location of the plates 1 and 2, which increases with the distance of the axis of turning of the plates. In addition, the force of compression of the spring 4 in the plates of fixation of location of the plates 1 and 2 is controlled to a maximum degree by the spring 4 and does not depend from the sizes of the plates 1 and 2. Analogously, the ring-shaped passage 11 and the ring-shaped projection 17 or insert 45 must be arranged at a distance close to the axis 3 as shown in Figure 15, 33. The plates 1 and 2 will turn coaxially, without eccentricity due to the interaction of the ring-shaped projection 17 of the insert 45 with the ring-shaped passage 11 , which also influences the accuracy of turning of fixation of the plates 1 and 2 among themselves as shown in Figure 10. The height of the ring-shaped projection 17 must be more than the height of the spherical projections 18 in orderto provide a constant engagement of the ring-shaped projection 17 with the ring-shaped passage 11 , which is necessary for coaxial turning of the plates 1 and 2.

The inserts 26 with the marks of color (symbols, reliefs) 27 identify both the location of the groups of the toy logical elements 29, and the mutual location of the plates 1 and 2. The inserts 26 with the marks 27 are formed permanent, non-removable and immovable. They are pressed-in or glued in the openings 7 shown in Figures 1 and 2.

However, for a substantial increase of attractiveness of the toy and its therapeutic properties, the plates 1 and 2 can be provided with setting openings 48 shown in Figure 48 for mounting of a movable turning inserts 49 and 50 shown in Figures 23-28, and also removable massaging attachments 51 and 52 with massaging projections 42 and setting projections 41 can be provided as shown in Figure 44.

A removable turning insert 49 is formed as a disk with ribs 53 for separation of the marks 27 and for convenience of turning. The insert 49 has a cylindrical lowering 54 with radially located grooves 55 for fixation of its turning, shown in Figures 46A-48, 50. The insert 50 is formed analogously to insert 49, however it has a central opening 56 which is necessary for a free passage of the centrai projection 8 of the toy shown in Figures 49A-50. The inserts 49 and 50 are located in the attachment 57 shown in Figure 46A. The attachment 47 is formed as a disk with setting projections 58, a throughgoing opening 59, a cylindrical lowering 60, a spherical formation 61 , two slots 62 and an undercut 63. The opening 59 is necessary for a free passage of the ribs 53 and marks 27 of the inserts 49 and 50. The inserts 49 and 50 are located in the attachments 57 and are jointly pressed in the setting openings 48 by the setting projections 58. A gap is provided between the lowerings 54 and 60. However, the turning insert 49 or 50 is pressed to the surface of the plate 1 or 2 by a spherical formation 51 shown in Figures 46B, 48, which has ability to spring due to the location of the slots 62 as shown in Figures 46A, 46B. The inserts 49 and

50 can be easily pressed out from the openings 48 and removed due to the undercuts 63 in the attachment 57 as shown in Figures 46B, 48. Instead of them, in the same openings 48, or other openings 48, massaging attachments

51 and 52 can be installed. They are removable, they have a setting projections 41 for easy pressing-in and an undercut 63, shown in Figures 44, 45 to simplify the removal.

The massaging attachment 51 and 52 are located in the places which are most convenient for massaging with fingers and provide maximum therapeutic effect during playing with the toy. For example the attachments 52 are preferably located at the base of the group of the toy logical elements 29, so that after turning of any of the elements 29, the fingers of a user can support against the massaging projections 42. The massaging attachments 51 are preferably located at the edge of the plates, so that a user can conveniently turn the plates and support with the fingers against the massaging projections as shown in Figures 23-25. Marks 27 shown in Figure 24 can be formed inside the massaging attachments 51. They simultaneously convert the attachments 51 into identifying elements for identification of location of the groups of the toy logical elements 29 on the plates 1 and 2, and also for identifying the mutual location of the plates 1 and 2. The massaging projections 42 can be simultaneously formed with the plates 1 and 2 so as to locate them along the outer parameter of the plates 1 and 2 continuously and discretely, for example only at the base of the groups of the logical element 29. The discrete location of the massaging projections 42, provides a possibility of selection for a user: it can be supported with the fingers against the massaging projections 42 during turning of the disks or not as shown in Figures 26, 27. The massaging projections 42 can be replaced with massaging reliefs 64 formed as simple attractive symbols as shown in Figure 28. These reliefs can be formed for identification of the mutual location of the plates 1 and 2 and designed together with them or separately from them. In other words they can be removable and located on the inserts, analogously to the massaging inserts 45. ln order to increase the springy properties of the arcs 5, they can be formed with the slots 65 shown in Figure 18 . The slots increase the accuracy of fixation of the toy logical elements 29 on the arcs 5 due to the additional spring-biasing of the arcs 5 and compensation of the tolerances of the size of toy logical elements 29.

The operation of the toy is performed in the following manner;

In the initial position the plates 1 and 2 are oriented so that the marks of color 27, reliefs 35, drawings 43 or numbers 44 provided on them coincide from both sides of the plates 1 and 2 as shown in Figures 3 and 5. In other words the plates 1 and 2 are located in order. Near the marks of the colors 27, (or relieves 35, drawings 43, numbers 44), groups of cylinders with toy logical elements 29 are located, which are also arranged in an order. In particular, the cylinder with the logical elements 29 of red color R is located between the marks 27 R, R of red color; the cylinder with the logical elements of green color G is located between the marks 27 G, G of green color; the cylinder with the logical elements 29 of yellow color Y is located between the marks 27 Y, Y of yellow color; the cylinder with the logical elements 29 of blue color B is located between the marks 27 B, B of blue color. In addition, within a group of cylinders with toy logical elements 29, the toy elements 29 which touch each other are also located in order by the relieves 35, drawing 43 and numbers 44. For example, the toy logical elements 29 can be located in an order with a sequence of reliefs I, II, III, INI, as shown in Figures 1 , 3, 5, 24, 28 in a sequence of drawings and symbols 43 as shown in Figures 23, 25, or numbers 44 as shown in Figures 26, 27.

The order of location of the toy logical elements 29 on the plates 1 and 2 in the initial position can be given both during assembly of the toy in a factory and also before the beginning of playing by a user. For this purpose, the toy can have both permanent immovable inserts 26 shown in Figured 1 -1 1 , and also removable turning inserts 49 and 50 shown in Figures 23 and 28.

During turning of the plate 1 relative to the plate 2 or visa versa as shown in Figures 10, 22, the spherical projections 18 of the plate 1 are disengaged from the depressions 13 of the plate 2 as shown in Figures 15 and 16. The plate 1 is lifted above the plate 2, but the ring-shaped projection 17 remains engaged with the ring-shaped passage 11 , since the height of the ring- shaped projection 17 is greater than the height of the spherical projection 18. The provision of the permanent engagement makes possible a concentric turning of one plate 1 relative to the other plate 2. The spring 4 provides a constant spring-biasing of the plate 1 and 2 and toy logical element 29. Together with the piate 1 , a half of the toy logical element 29 is displaced as well as shown in Figures 10, 20. They slip with their surfaces along the inner surface of the neighboring plate and along the surfaces located on the neighboring plate of the toy logical element 29. The relative turning of the plates 1 and 2 continues until engagement of the spherical projections of the plate 1 with the depressions 13 of the plate 2. The angle of turning of one plate relative to one another can be a multiple of 360°/K where K is a number of groups of cylinders with the toy logical elements 29 on the plates 1 and 2 and having a common axis of turning. For example, if the toy has four groups of cylinders with toy logical elements 29 as shown in Figures 1 , 23, 25, then a minimal angle of the turning of the plates is equal to 360 4 or 90°. If the toy has three groups of cylinders with toy logical elements 29 as shown in Figures.24, 28, the minimal angle of turning of the plates is equal to 36073 or 120°, If the toy has eight groups of cylinders with toy logical elements 29 as shown in Figure 26, the minimal angle of turning of the plates is equal to 36078 or 45°.

A special case is a toy shown in Figure 27, since on the plates 1 and 2 there are 16 groups as cylinders with toy logical elements 29, and the cylinders are located on the plates in pairs, radially and with offset therebetween by an angle L°. In this case the angle of turning of the plates 1 and 2 can be equal to 3607K + L°, 3607K, 3607K - L°, L°, where K is a number of pairs of groups of the cylinders of the toy elements 29, L° is an angle between two groups of cylinders of toy logical elements 29 in a pair. The displacement of the plates 1 and 2 leads to the turning of a half of group of cylinders with toy logical elements 29 about a central axis of turning of the plates 1 and 2 or a conditional axis Z shown in Figures 10 and 20. In such an intermediate position, the toy logical elements 29 can not rotate since their surfaces are located on the surfaces of the plates 1 and 2. After the final turning or additional turning of the plates 1 and 2 by an angle which is a multiple of 3607Kthe spherical projections 18 of the plate 1 again engage with the depressions 13 of the plate 2. The plates 1 and 2 are easily stopped therebetween by the projections 18 and depressions 13, Halves of cylinders of the groups of toy logical elements 29 coincide, and there is again a possibility of turning around conditional common axes of the cylinders X and Y as shown in Figures 19 and 21.

The new position of the plates 1 and 2 is characterized by the fact that the toy is already disoriented, since the marks of color 27, drawings 43, or numbers 44 from both sides of the plates 1 and 2 do not coincide. In addition, the integrity of the groups of cylinders of the toy logical element 29 is distorted, since within each group of the cylinders, the toy logical elements 29 of different colors will be located and not as the same color as in the initial position.

The next step is turning of the game logical elements 29 within each group by angle ° which is a multiple of the angle of opening of the toy logical element 29. In other words, if the toy is composed of toy logical elements 29 formed as one half of a cylinder, then the angle of turning of the toy logical elements M° will be a multiple of 36072 or 180°; if the toy is composed of toy logical elements 29 formed as one quarter of a cylinder, the angle of turning of the toy logical elements M° will be a multiple of 36074 or 90°; if the toy is composed of toy logical elements 29 formed as 1/6th of a cylinder, then the angle of turning of the toy logical element M° will be multiple of 36076 or 60° as shown in Figure 39A-43, etc. During turning of the toy logical elements 29 above the conditional axis X and Y as shown in Figure 19 located on the collars 30 of the toy logical elements 29, the fixators formed as projections 36 and depressions 37 and 38 are disengaged from the slots 14 and the projection 15 on the arcs 5 of the plates 1 and 2 as shown in Figures 16, 17. The plates 1 and 2 depart as shown in Figure 16 and at the same time remain biased by the spring 4 shown in Figures 12, 13. In the moment of turning of the toy logical elements 29, the plates 1 and 2 can not turn since the inner contacting or mated surfaces of the plates 1 and 2 do not coincide with all surfaces of the toy logical elements 29 or in other words they are not aligned. After turning of the toy logical elements 29 by angle M°, the projections 36 or depressions 37 and 38 engage with the slots 14 and projections 15 on the arcs 5 on the plates 1 and 2 shown in Figure 16, 17. The plates 1 and 2 are pressed under the action of the spring 14. The planes of the toy logical elements 29 are aligned with the inner mated surfaces of the plates 1 and 2. The position of the toy logical elements 29 is again fixed by the projections 36 and slots 14 or depressions 37 and 38 and the projections 15 as shown in Figures 14, 17, 18.

The new position of the toy is characterized by the fact that the plates 1 and 2, as well as the toy logical elements 29 have a possibility of turning; however, their mutual location in correspondence with the marks 27, relieves 35, drawings 43, numbers 44 is distorted,

The objective of a user is by a successive alternative turning of the plates 1 and 2 and toy logical elements 29, to restore the initial mutual position of all parts of the toy, or in other words of the plates 1 and 2, the toy logical elements 29, the marks 27, the relieves 35, the drawings 43, the numbers 44. Or the objective is to create a new predetermined color pattern, a new sum of numbers, a new word, a new relief, etc.

The massaging inserts 40, and the attachments 51 and 52 impart to the toy new therapeutic properties, since they provide massaging of user's fingers during the process of turning of the parts of the toy.

The removable turnable inserts 49 and 50 with the attachment 57 operate in the following manner. In the initial position the toy is assembled as shown in Figure 23. The drawings 43 on the toy logical elements 29 and their colors correspond to the drawings 43 and the colors 27 Y, R, G, B of the insert 50 and the attachment 57. The user turns the insert 50 by the ribs 53 by the angle which is a multiple of 3607K, wherein K is a number of groups of cylinders of the toy logical elements 29, in this case K equals 4. During turning of the insert 50, the groove 55 is displaced, the spherical formation 61 which spring biases the insert 50 is lifted due to the slots 62 as shown in Figure 46A, 46B. The position of the insert 50 is no longer fixed. When the spherical formation 61 engages in a next groove 55, the position of the insert 50 is again fixed as shown in Figure 48. As a result of turning of the insert 50, the mutual position of the plates 1 and 2 is distorted since the marks of color 27 for the plates 1 and 2 no longer coincide from both sides, In addition, the colors on the toy logical elements 29 do not correspond to the colors 27 of the insert 50. A user must successively turn the plates 1 and 2 and the toy logical elements 29 so as to restore the initial position, without changing the position of the insert 50.

The operation of the insert 49 and 50 in Figures 25, 26, 27 is analogously to the one described above. The marks of colors 27, the drawings 43, the numbers 44 around the inserts 49 and 50 determine the position of the toy logical elements 29 with the same marks of color 27, drawings 43, numbers 44 on the plates 1 and 2 from both sides. The turning of at least one of the inserts 49 or 50 by an angle to its next fixation converts the toy into a disoriented position since on the toy logical elements 29 of the marks of color 27, drawings 43 or the numbers 44 do not correspond to the position of the same marks, drawings or numbers on the inserts.

The insert 49 and 50, as well as the massaging attachments 51 and 52, can be easily pressed out from the plates 1 and 2 of the toy when it is not needed or complicated. For this purpose on the attachments 51 , 52 and 57 there are undercuts 63.

The logical toy of the invention includes a logical game element in accordance can be formed as a part of a cylinder, for example Vέ, 114, 1 /6, etc. At both sides of the element, it is provided with projections 1 , as shown for example in Figures 51 A, 51 B, 51 C, 52A, 52B, etc. Regardless of the shape of the logical game element, the projections 1 are formed as a part of a body of revolution, or in other words as a part of a cylinder or a part of a sphere.

Front surfaces of the logical game element which is formed as a part of a cylinder or a gear are provided at both^' sides with radii 2 as shown in Figures 51 A, 51 C, 51 F, 57A, 58A, 58C, 59A, 59C, 60C. The radii 2 can be replaced with chamfers (which are shown in hidden lines on the Figures 51 C). The surfaces of the projections 1 near a base are also rounded from two sides. In other words, they are provided with a radii 3 as shown in Figures 51 A, 51 B, 51 C, 51 F, 52B, 53B, 58C, 59C, 60C. The radii 3 can be also replaced by chamfers (which are shown in hidden lines on the Figure 51 C). The surfaces which are formed by intersection by a cylinder or a gear with planes into several parts (main surfaces of the logical game element), are rounded from two sides by radii 4, as shown for example in Figures 51 A, 51 B, 52A, 52B, 53A, 53B, 53D, 58B, 59B, 60B. They are rounded between themselves with radii 5 as shown for example in Figures 52A, 52B, 52D, 53B, 53D, 59B, 60A, 60B.

Both the radii 2 and 3 as well as the radii 4 and 5 can be replaced by chamfers. However, the use of the radii instead of the chamfers is preferable, since it makes the displacement of the logical game elements in the games smoother, without jumps and blocking.

The outer surface of the logical game element can be provided with a relief 6 formed as a predetermined number of marks and lines, such as for example in Figures 51 A, 51 B, 52C, 52D, 52E, 52G, 52K, 52M. They can be used both for providing a logical order of elements in the process of a game, for example to arrange the elements in accordance with the order I, II, III, INI, and also for playing by deaf people with touching of the elements.

The projections 1 , or at least one of the projections, or in other words from at least one from side of the logical game element, fixing members for fixing a position of the element are provided. The fixing members are formed as steps 7, as recesses 8, or as double steps 9 as shown in Figures 51 B, 51 E, 52B, 53D, 53F. The logical game elements can be also provided with a front slot formed as a dovetail 10, as shown for example in Figures 51 G, 52A, as a rectangle 1 1 as shown for example in Figures 51 L, 51 M, 51 N or can be provided with flat 12 on an apex as shown for example in Figures 510, 51 P, The base of the slots 10 and 1 1 or the flat 12 which is located below the upper point of the projection can also serve for fixing a position of the logical game element, as shown for example in Figures 51 H, 51 N.

At least one setting opening 13 can be provided on the base 11 or 12 as shown in Figures 51 L, 510. Generally, the front slot 10 can be formed as any shape, which is open or in other words not closed, near an apex of the logical game element. The provision of the front slot 10, 11 or the flat 12 makes possible to use inserts 14, 15, 16 which are provided for expanding of functional and gaming possibilities of the logical game element.

The insert 14 can tightly engage into the front slot 10 and be retained in it, since the slot 10 is formed as a dovetail as shown for example in Figures 54A, 54B, 54C. The inserts 15 and 16 have setting projections 17 so as to provide a possibility of pressing of the inserts into the opening 13, located at the base of the slot 1 1 or on the flat 12 as shown in Figures 55A, 55B, 55C, 56A, 56 B, 56C. Massage projections 18 can be formed on the inserts 14, 15 for action on nervous centers of fingers during displacement of the logical game elements as shown in Figures 54A, 54B, 54C, 55A, 55B, 55C. Also, various reliefs and images 19 can be applied on the logical game elements, such as shown in Figures 57A, 57B, 57C, so as to provide different games, develop a logical thinking, a spacial imagination, sensitivity of fingers, etc.

Instead of the reliefs 6, the surface of the logical game element can be provided with teeth 20 which form the elements as a part of a gear (Vz, 1/4, 1/6, etc). However, the radii 2, 3, 4, 5 and also the fixing members 7, 8, 9 remain in this elements, as shown in Figures 58A-16C. The teeth 20 make possible an interaction between the logical game elements by engaging the logical game elements with one another. It improves the attractiveness of the games, expands the possibilities of forming new attractive logical and mechanical games and toys. The logical game element can be formed as V≥, 114, 1 /8 of a sphere 21 , The surface of the sphere can be provided with at least one fixing member 8 for fixing the position of the element as shown in Figures 61 A, 61 B, 61 D, 61 F. 64B.

The steps 22 on the surface of the sphere 21 increase the convenience and attractiveness of the game since the step 22 is an additional guide for rotation of the spherical logical game element. It is also an additional support for fingers during rotation of the element, It can be also used as an additional spot for an image 19, a mark or a relief, as shown in Figures 62B, 63A, 64A. The radii 3, 4, 5 still remain on the logical game element, while the radius 2 is absent since this sphere is used instead of the cylinder, Also, this element still has the fixing member 8 on the surface of the sphere as shown in Figures 62A-64B.

The image 19 can be applied on the surface of the sphere 21. The logical game element formed as a sphere has 6° of freedom, so that the possibility of forming new attractive logical games is expanded,

The use of fixing members and the radii is common for all logical game elements, regardless of their shape, type, the presence of slots and inserts. This makes possible to increase the convenience of the existing and future logical games. The provision of the slots, inserts, teeth, steps, images, relieves increases the attractiveness of the new games, expands a range or assortment of the new games, toys and puzzles.

The main feature of the present invention is that the radii or chamfers are provided on the sides which are located in planes to be contacted with one another or to slide over one another during assembly of an object composed of at least two logical game elements or disassembly of the same. This is illustrated in Figures 65 and 66. Figure 65 shows two elements illustrated in Figure 51 A and brought in contact with one another so that they can slide over one another. The surfaces of the elements 1 A which are in contact with one another and slide over one another are provided with the radii or chamfers 4. The same is true for the elements in Figure 64A assembled as shown in Figure 66. The surfaces which face one another and are in contact with one another and slide over one another are provided with the chamfers 4. This feature is not disclosed in the art and can not be derived from it.

It will be understood that each of the elements described above, or two or more together, may also find a useful application in other types of constructions differing from the types described above.

While the invention has been illustrated and described as embodied in logical toy, it is not intended to be limited to the details shown, since various modifications and structural changes may be made without departing in any way from the spirit of the present invention.

Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can, by applying current knowledge, readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention.

What is claimed as new and desired to be protected by Letters Patent is set forth in the appended claims.
