Abstract

The invention is concerned with four-dimensional ball. It is a tetrahedron made up of four regular triangles and the rim of regular triangle is symmetrical arcs sticking out, and is filled as a protruding ball. The four surfaces have numerical value to print mark and picture and it is fit for playing indoors and outdoors, especially in park or beach and lakefront. When tap some part of the ball with suitability power and angle, it will move in air with different speed and angle. It is fit for all kinds of people to improve the correspond movement ability and quickly response ability by dealing with the speed and angle, and form acute feeling of apace and time by forecasting and judging the changing trend of movement space. It is easy for carrying and needs small place, is fit for deeply exploitation for commonweal and business with some playing patterns, such as standard testing, value pile, point tend and sports match.

Description

Four-dimensional ball

(1) technical field

The sports goods class in motion, leisure field.

(2) background technology

But the aerial indefinite floating power-assisted of common balloon is gone up to the air and the free falling characteristic.Positive cubical spatial symmetry in four sides and multiaspect thereof are rotated overstable characteristic.Vollyball, basketball, handball, water polo etc. mainly are the amusement or the sports characteristic of the ball sports item of direct contact with hand not by instrument.

(3) summary of the invention

1. general description

The original four-dimensional ball in native country can be regarded the positive tetrahedron that is made of four triangulars as, its equilateral triangle edge is the distortion of camber line symmetrically and a kind of outdoor activity near-spherical positive tetrahedron of forming to evagination, handles relay and bounces the continuous operation that can do friction speed, angle and rotation aloft.

2. technical problem that will solve and outward appearance and somatotype

Each face evagination of this positive tetrahedron is curved surface shape symmetrically, and any one side is adjacent with other three, the seamless spliced successively adhesion in its edge, disposable or repeatedly filling form the positive four sides of evagination near-spherical cube (Fig. 1).Its each limit is the long 24-48cm of rib, with rib to be 1/6 arc (Fig. 2) of radius circle.The positive four sides of standard cube rib is long to be 36cm, this moment camber line segment length 37.68cm, each face area equates to be 912cm ², the gross area is 3648cm ²(Fig. 3).Four facades should be given numerical symbol respectively, and can print mark of correlation, also can select the color background pattern for use.Can be divided into light-duty, heavy and excessive type between the two.Light-duty volume is bigger, and the hang time is longer, and angled rotation is more slow, and it is slower that equal strength is bounced the speed of service, otherwise heavy type then.

3. the technical scheme and the main material that solve its technical problem and adopted

Recommend to use the three-dimensional expansion setting-out of computer printing, the specification precision is higher; Can adopt that the high frequency plastic cement mode of welding is spliced, craft or machinery sewing splicing, the moulding of injection moulding mode etc., less with assurance geometric distortion; Outer surface mark and pattern are taked the painted durable wear of serigraphy.Make material and can adopt 1. rubber, 2. composite coating industrial plastics such as PVC and the toughness reinforcing polymerization PVC of super firm hot carbon, PEVA, PU, PE, 3. leather or artificial leather, 4. other textiles such as Oxford waterproof cloth.Positive four sides cube uniform layer thickness 0.25 is to 2.5mm, and quality is 25 to 250 grams, and one side central authorities can stay filling to use valve road junction (Fig. 1-3) therein.Manufactured goods have certain elasticity, and nontoxic nothing is smelt, water proof and dust proof, flame-proof heat-resistant, freeze proof shock resistance against corrosion.

4. the function of four-dimensional ball and beneficial effect

Thing of the present invention is light portable, and the activity floor space is little, can develop criterion test, numerical integration, count and walk quickly and keep away and multiple a series of activities mode such as athletic competition, has the health care that easypro body exhibition arm, brain tonic are pleased the heart.Intersect change hand bounce action can be initiatively or passivity bend and stretch four limbs and backbone, improve the particularly coordinated movement of various economic factors ability of head, neck, eye, hand of parts of body, by selection strain to operating four-dimensional ball speed and angle, temper quick-reaction capability, raising is to the prediction and the determined level of moving object spatial position change trend, to form sharp space-time sense gradually.

(4) description of drawings

Four any one sides of face of globoid are adjacent successively with other three faces, can be defined respectively.When being horizontal positioned complete face cover to sight line other two for the A face, overlook two proximal surfaces being covered by the A face to expose this moment, A face counterclockwise proximal surface is the B face, and the proximal surface of A face clockwise direction is the C face, then draws for D with A, B, three bottom surface adjacent of C respectively.Pairing A, B, C three hand-deliver remittance summits are the D point directly over definition and the D face simultaneously, the in addition three hand-deliver meeting points corresponding with the B face are the B point, the in addition C point of three hand-deliver meeting points corresponding with the C face, the in addition three hand-deliver meeting points corresponding with the D face are the D point, each four-dimensional ball has A, B, four points of C, D.The camber line that defines A, the adjacent connection of B face simultaneously is AB edge (line, an arc), the camber line of A, the adjacent connection of C face is AC edge (line, an arc), the camber line of A, the adjacent connection of D face is AD edge (line, an arc), the camber line of B, the adjacent connection of C face is that the camber line of BC edge (line, arc), B, the adjacent connection of D face is BD edge (line, an arc), the camber line of C, the adjacent connection of D face is CD edge (line, an arc), and each four-dimensional ball has six edge (line, arc).
