Description
- The present invention relates to a rotary exercise apparatus which a user enters and with which a user rotates for carrying out muscle training and enhancing the sense of equilibrium.
- As a rotary exercise apparatus which a user enters and with which a user rotates for carrying out muscle training and enhancing the sense of equilibrium, those suggested in the
patent references 1 to 4 are known, for instance. Each of the rotary exercise apparatuses suggested in thepatent references 1 to 3 is comprised of a gimbal comprised of three rings and supported on the ground. A user entering the rotary exercise apparatuses can rotate in any direction merely by moving his/her weight. - The rotary exercise apparatus suggested in the
patent reference 4 includes grips disposed at an upper area in a spherical frame comprised of vertical and horizontal frames, and feet fixture disposed at a lower area both in a spherical frame comprised of vertical and horizontal frames. A plurality of hard balls is rotatably mounted over an outer surface of the frame defining a sphere. The spherical frame is rotatably mounted on a pedestal having a semispherical recessed surface corresponding to a semispherical outer surface of the spherical frame. - Patent reference 1: U.S. Pat. No. 4,799,667
Patent reference 2: Japanese Patent Application Publication No. 62-64377
Patent reference 3: Japanese Patent Application Publication No. 57-203947
Patent reference 4: Japanese Utility Model Application Publication No. 52-11455 - In the rotary exercise apparatuses suggested in the
patent references 1 to 3, a user puts his/her body within an innermost ring for rotation exercise. In rotation exercise, the three rings rotate relative to one another in the vicinity of one another. Accordingly, if a user's limbs mistakenly protruded out of an innermost ring, the limbs would be dangerously in the orbit path of other rings. In the rotary exercise apparatus suggested in thepatent reference 4, since the spherical frame and the semispherical recessed surface are quite close to each other with almost no space between them, it would be dangerous if a user's limbs mistakenly protruded out of the spherical frame. - In view of the above-mentioned problems, it is an object of the present invention to provide a rotary exercise apparatus which is capable of keeping a user safe, even if the user's limbs mistakenly protruded out of a frame.
- The rotary exercise apparatus in accordance with the present invention includes a contour frame defining a regular polyhedron, balls each rotatably supported at a position outside of each of the vertices of the contour frame defining a regular polyhedron, and a pedestal having a semispherical surface inscribing the balls of the contour frame therein, and rotatably supporting the contour frame therein. In the rotary exercise apparatus in accordance with the present invention, when the contour frame defining a regular polyhedron is rotating within the semispherical surface of the pedestal, a certain space is formed between each of planes of the contour frame and the semispherical surface. Thus, even if a user's limbs protrude while exercising, out of planes of the contour frame, it would be possible to keep a user safe.
- Preferably the polyhedron is a regular icosahedron or a regular dodecahedron. A regular polyhedron includes a regular tetrahedron, a regular hexahedron, a regular octahedron, a regular dodecahedron and a regular icosahedron. Since a regular tetrahedron, hexahedron and octahedron has 4, 8 and 6 vertices, respectively, a number of vertices making contact with the semispherical surface is too small to allow the contour frame to rotate in the semispherical surface, resulting in difficulty in smooth rotation. In contrast, since a regular dodecahedron and icosahedron has 20 and 12 vertices, respectively, it is possible to sufficiently disperse loads acting on the balls disposed at the vertices, ensuring smooth rotation in the semispherical surface.
- Preferably the rotary exercise apparatus in accordance with the present invention includes a feet fixture for fixating feet of a user at a position inside of a frame of the contour frame defining a regular icosahedron or a regular dodecahedron, and a hands fixture for fixating hands of the user at a position inside of a frame disposed in facing relation to the frame at which the feet fixture is arranged. In a frame defining a regular icosahedron or dodecahedron, since a pair of frames facing each other is parallel to each other, it is possible to readily mount a feet fixture and a hands fixture at the pair of frames, ensuring that a user entering the contour frame can fix his/her hands and feet, by stretching his/her hands and feet.
- Preferably the rotary exercise apparatus in accordance with the present invention includes a protection ring for restricting an area in which a body of the user moves, the protection ring being arranged within a plane perpendicular to a plane including the frame at which the feet fixture is arranged and the frame at which the hands fixture is arranged, a belt wound around a body of the user within the protection ring, and a rope for connecting the protection ring to the belt. The belt wound around a body of a user within the protection ring is connected to the protection ring through the rope. This ensures that since hands, feet and body of a user are caused to stay in the protection ring in a plane including a frame at which the feet fixture is arranged and a frame at which the hands fixture is arranged, even if a user fainted or lost consciousness while exercising, it would be possible to prevent the user from protruding out of the contour frame.
- (1) Since the rotary exercise apparatus may include a contour frame defining a regular polyhedron, balls each rotatably supported at a position outside each vertices of the contour frame defining a regular polyhedron, and a pedestal having a semispherical surface inscribing the balls of the contour frame therein, and rotatably supporting the contour frame therein, a certain space is formed between each of the planes of the contour frame and the semispherical surface. Thus, even if the limbs of a user protruded outside the planes of the contour frame while exercising, it would be possible to keep a user safe.
- (2) By designing the polyhedron to be a regular icosahedron or a regular dodecahedron, it is possible to sufficiently disperse loads acting on the balls disposed at the vertices, ensuring smooth rotation in the semispherical surface.
- (3) Since the rotary exercise apparatus may include a feet fixture for fixating the feet of a user at a position inside of a frame of the contour frame defining a regular icosahedron or a regular dodecahedron, and a hands fixture for fixating the hands of the user at a position inside of a frame disposed in facing relation to the frame at which the feet fixture is arranged, it is possible to readily mount a feet fixture and a hands fixture at the frames, ensuring that a user entering the contour frame can fix his/her hands and feet, by stretching his/her hands and feet.
- (4) Since the rotary exercise apparatus may include a protection ring for restricting an area in which a body of the user moves, the protection ring being arranged within a plane perpendicular to a plane including the frame at which the feet fixture is arranged and the frame at which the hands fixture is arranged, a belt wound around the body of the user within the protection ring, and a rope for connecting the protection ring to the belt, it is ensured that since hands, feet and body of a user are caused to stay in the protection ring in a plane including a frame at which the feet fixture is arranged and a frame at which the hands fixture is arranged, even if a user fainted or fell unconscious while exercising, it would be possible to prevent the user from protruding out of the contour frame.

Theprotection ring 8 is supported in thecontour frame 2 by means ofsupport pipes 8 a. Thebelt 9 is comprised of, for instance, a hook-and-loop fastener for fitting to and fixing a body of the user P. Theprotection ring 8 and thebelt 9 are connected throughconnection ropes 9 a such that thebelt 9 can move only within theprotection ring 8. - In use of the rotary exercise apparatus having the above-mentioned structure, the user P enters the
main body 1 of the rotary exercise apparatus through an opening of thecontour frame 2, and then, fixes his/her feet to thefeet fixtures 6 and puts thewrist bands 7 c around his/her wrists, and then, grasps thegrips 7 a. Thereafter, moving his/her center of gravity by twisting or shaking his/her body, themain body 1 of the rotary exercise apparatus rotate on thesemispherical surface 4 of thepedestal 5. Thus, the user P can carry out muscle training and enhance the sense of equilibrium. - Since the rotary exercise apparatus in accordance with the present embodiment is comprised of the
contour frame 2 defining a regular icosahedron, theballs 3 each rotatably supported at a position outside of each of vertices of thecontour frame 2 defining a regular icosahedron, and thepedestal 5 having thesemispherical surface 4 inscribing theballs 3 of thecontour frame 2 therein, there are formed spaces between peripheral planes of the contour frames 2 and thesemispherical surface 4. Accordingly, even if the limbs of the user P protruded out of the peripheral planes of thecontour frame 2 to some degree while exercising, it would be possible to keep the user P safe. - Furthermore, it is possible to separate the
connectors 3 a and thepipes 2 a from each other while the rotary exercise apparatus in accordance with the present embodiment is not in use or is being carried, the rotary exercise apparatus is more suitable in storage and carriage than the conventional rotary exercise apparatuses. - The
contour frame 2 in the rotary exercise apparatus in accordance with the present embodiment is in the form of a regular icosahedron, and has twelve (12) vertices supported by. theballs 3. Accordingly, if thesemispherical surface 4 of thepedestal 5 defines an intrinsic semispherical surface, that is, one of halves obtained by dividing a ball into two pieces with a plane passing a center of the ball, a half of the vertices, that is, the six vertices always make contact with thesemispherical surface 4, ensuring to the possibility of sufficiently dispersing loads acting on theballs 3 supported at the vertices. Thesemispherical surface 4 illustrated inFIGS. 1 and 2 defines a smaller one among halves of a ball obtained when the ball is divided into two pieces with a plane passing out of a center of the ball, even in which case, the three vertices make contact with thesemispherical surface 4, ensuring that themain body 1 of the rotary exercise apparatus is able to smoothly rotate within thesemispherical surface 4. - Furthermore, the rotary exercise apparatus in accordance with the present embodiment may be designed to include
fixture 11 as illustrated inFIGS. 8A and 8B in order to prevent themain body 1 of the rotary exercise apparatus from rotating when the user enters or leaves the contour frame.FIG. 8A illustrates how thefixture 11 operates when the rotary exercise apparatus is in use, andFIG. 8B illustrates how thefixture 11 operates when the user enters or leaves the rotary exercise apparatus. As illustrated inFIGS. 8A and 8B , thefixture 11 is comprised of, for instance,arms 12 supported at thefoot plate 6 a such that thearms 12 can raise and lower, andrubbers 13 mounted at distal ends of thearms 12 for preventing slip. When the user enters or leaves the rotary exercise apparatus, as illustrated inFIG. 8B , thearms 12 are lowered to compress therubbers 13 onto thesemispherical surface 4 of thepedestal 5, resulting in that thecontour frame 2 is kept not moved. When the rotary exercise apparatus is in use, as illustrated inFIG. 8A , thearms 12 are raised to thereby release therubbers 13 from thesemispherical surface 4, resulting in that thecontour frame 2 can rotate. - In place of the
contour frame 2, there may be employed acontour frame 10 defining a regular dodecahedron which is one of polyhedrons, as illustrated inFIG. 9 . Thecontour frame 10 is comprised of thirtypipes 10 a each connecting each of twenty vertices of the regular dodecahedron to three vertices therearound, andconnectors 10 b similar in structure to theconnectors 3 a. Thecontour frame 10 has twelve peripheral planes which are in the form of a regular pentagon. Thecontour frame 10 includesballs 3 each rotatably supported at a position outside of each of the twenty vertices of the regular polyhedron, similarly to thecontour frame 2. Though not illustrated, thecontour frame 10 includes thefeet fixtures 6 and thehands fixtures 7, similarly to thecontour frame 2. - Since the
contour frame 10 defining a regular dodecahedron has twenty vertices which are greater in number than the twelve vertices of thecontour frame 2 defining a regular icosahedron, it is possible to cause threeballs 3 to always make contact with thesemispherical surface 4, even if thesemispherical surface 4 is formed smaller, ensuring that it is possible to form thepedestal 5 smaller in size. Thus, it is possible to lessen an area in which the field of view of the user is shut out by the pedestal while the user P entering the contour frame is rotating with his/her head directing downwardly, ensuring that a sense of oppression caused by the field of view of the user being shut out can be lessened. - The
contour frame 2 defining a regular icosahedron has high intensity, because the peripheral planes define a regular triangle which is dynamically most stable. Furthermore, since thecontour frame 2 defining a regular icosahedron has a small number of vertices, specifically, twelve vertices, it is possible to arrange a small number of theballs 3. Since the rotatably supportedballs 3 increase fabrication costs and cause the rotary exercise apparatus to be heavy in weight, it is possible to reduce fabrication costs of the rotary exercise apparatus by reducing a number of theballs 3. - Furthermore, since the rotary exercise apparatus in accordance with the present embodiment may be designed to include the
feet fixtures 6 for fixating the feet of the user at a position inside of thepipe contour frame 2 defining a regular icosahedron or a regular dodecahedron, and thehands fixtures 7 for fixating the hands of the user at a position inside of thepipe pipe - In the rotary exercise apparatus in accordance with the present embodiment, if the contour frames 2 and 10 had a common outer diameter (a diameter measured from a center to the balls 3), it would be possible to use a
common pedestal 5, ensuring that the user P can select any one of them by his/her preference. - Furthermore, since the rotary exercise apparatus in accordance with the present embodiment may be designed to include the
protection ring 8 for restricting an area in which a body of the user P moves, the protection ring being arranged within a plane perpendicular to a plane including both thepipe 2 a at which thefeet fixtures 6 are arranged and thepipe 2 a at which thehands fixtures 7 are arranged, thebelt 9 wound around a body of the user P within theprotection ring 8, and therope 9 a for connecting theprotection ring 8 and thebelt 9 to each other, it is ensured that since hands, feet and body of the user P are caused to stay in theprotection ring 8 in a plane including thepipe 2 a at which thefeet fixtures 6 are arranged and thepipe 2 a at which thehands fixtures 7 are arranged, even if the user P fainted or fell unconscious during exercise, preventing the user from protruding out of thecontour frame 2. - The rotary exercise apparatus in accordance with the present invention is useful as an exercise apparatus which a user enters and with which a user rotates for carrying out muscle training and enhancing the sense of equilibrium.
