Abstract

The utility model relates to a tri-ball which is a three-dimensional sphere formed by that three circular slices are mutually vertically intersected, and a reinforcing rib is arranged on the periphery of each circular slice. The utility model has the advantages of light weight and enlarged contact area between the sphere and air, and when moving as sports goods, the air resistance of the utility model is large, so the speed of the tri-ball is low without causing injury accidents. The utility model can be flapped by a racket and can be thrown like earthbags and softballs, and when used as an advertisement carrier, the utility model is provided with more than eighteen equal vision-area surfaces facing in all directions. Letters and patterns on the utility model can be seen form any direction, and the information carrying quantity of the unit time-space advertisement carrier can be enhanced.

Description

Tri-ball

The utility model relates to a kind of physical culture, culture and amusement article, particularly is a kind of Tri-ball.

The sand hill, the softball that are used for physical training, the speed of service is very fast when throwing.The thrower just dare not be with big strength during close together, and its reason one is to be afraid of that firmly too big excessive velocities the other side connects incessantly, and two are afraid of to beat the other side hindering the other side on one's body.So, the thrower just can not give full play to strength when pitching, has weakened the exercise effect.How can make throwing sand hill, softball person when throwing exercise, give full play to throwing strength, can make the receiver catch ball very like a cork again? when shot is thrown in exercise, we normally utilize the weight of shot to make resistance, shot is heavy more, the resistance that overcomes when throwing exercise is big more, and the exercise that muscle obtains is strong more.This is no doubt fine, but shot focuses on very much in the exercise and will take care constantly, preventing to beat the accident that damages on health, and can only practise on the ground throwing at earth.In addition, being easy to notice that present advertising carrier is normally unidirectional, is three-dimensional at most.This type of advertising carrier has tunnel vision, and space availability ratio is low.How to improve advertising carrier in the information publication amount that guarantees to improve under the impregnable prerequisite of advertising results unit space-time?

The utility model just is based on the problems referred to above and produces, and purpose is: a kind of lightweight sports entertainment article that reduces injury accident is provided.

Described Tri-ball constitutes a three-dimensional sphere by three mutual square crossings of disk, applies on the periphery of disk and is equipped with reinforcement.Have four wedge mouths of at right angles arranging mutually 11 on the periphery of disk 1; Have two wedge mouths 21 on the straight line that coexists on disk 2 peripheries, have a wedge groove 22 with this wedge mouth vertical direction; Have an orthogonal cross wedge groove 31 on the disk 3.Two the wedge mouth sums of every disk on same straight line add the wedge groove or add the length of cross wedge groove and the equal diameters of disk.The width of wedge mouth, wedge groove equates with the disk wall thickness or is slightly larger than wall thickness.

Described Tri-ball light weight has also increased the contact area of spheroid and air, and air drag is big during motion, so speed is slower, can not damage accident; Can pat with racket, can resemble and throw sand hill, the softball; Be used as shot and carry out spoke and help when training, shot is thrown 8 meters, and Tri-ball equally also can only be thrown 8 meters, therefore can throw in exercise on the timber floor or on the cement flooring.Described Tri-ball has the above vision area of 18 faces to equate, towards from all directions, stand in any direction and can see character pattern on the Tri-ball body, therefore also be suitable for doing very much advertisement information carrier and use, to improve the information publication amount of unit space-time advertising carrier.

Fig. 1 is the utility model structural representation.1,2,3 is three disks among the figure, and 4 is the reinforcement on the disk periphery.

Exploded view when Fig. 2 is used as advertisement information carrier for the utility model.1 is that disk 1,11 is for opening four wedge mouths of at right angles arranging mutually on the disk 1 among the figure; 2 is that disk 2,21 is two the wedge mouths on the straight line that coexists of opening on disk 2 peripheries, and 22 by being opened the wedge groove with this wedge mouth vertical direction; 3 is that

disk

3,31 is by being opened orthogonal cross wedge groove on the disk 3.

Described Tri-ball as advertising carrier can add material making such as cloth with art paper, clamping plate, metallic plate or steel wire.Earlier above-mentioned material is made the circle of three equal diameters, stamped out wedge mouth, wedge groove, then disk 1 is passed from the wedge groove 22 of disk 2, disk 1 is inlayed by wedge mouth 11 and wedge groove 22 with disk 2 closed with mould; At last the cross wedge groove of disk 3 on it and disk 1,2 are inlayed mutually and closed and constitute described Tri-ball.Spheroid is changeable, all can publish advertising message on each face that forms.

As the described Tri-ball of amusement and physical culture, can with toughness better, materials such as the lighter plastics of weight or rubber make, the reinforcement on the disk periphery is advisable with steel wire, can one-shot forming in mould.

Claims

1. a Tri-ball is characterized in that, described Tri-ball constitutes a three-dimensional sphere by three mutual square crossings of disk, applies on the periphery of disk and is equipped with reinforcement.

2. Tri-ball as claimed in claim 1 is characterized in that: have four wedge mouths of at right angles arranging mutually 11 on the periphery of described Tri-ball disk 1; Have two wedge mouths 21 on the straight line that coexists on disk 2 peripheries, have a wedge groove 22 with this wedge mouth vertical direction; Have an orthogonal cross wedge groove 31 on the disk 3; Two the wedge mouth sums of every disk on same straight line add the wedge groove or add the length of cross wedge groove and the equal diameters of disk; The width of wedge mouth, wedge groove equates with the disk wall thickness or is slightly larger than wall thickness.
