Abstract

An improved bat structure has at least a PU casting hi-rebound annular hollow member in the space interiorly of the inner wall of the hitting area of the bat and is clung to the inner wall of the hitting area. The annular hollow member can have the function of eliminating the vibration induced by collision between a ball and the bat when in hitting. And an instantaneous rebound force generated by the PU annular hollow member can also increase hitting power; furthermore, because of the fast restoration characteristic of the PU material in impacting, the deformation of the bat caused by long-term use will be reduced to help extend life-span of the bat.

Description

    BACKGROUND OF THE INVENTION
  • 1. Field of the Invention [0001]
  • The present invention is related to an improved bat structure; and especially to such an improved bat structure of which the space interiorly of the inner wall of the hitting area is placed therein PU casting hi-rebound annular hollow members, in order to eliminate the vibration induced by the reaction force during hitting, and to increase the hitting force by generating instantaneous rebound by the highly resilient PU, the bat structure therefore could help the players act well in hitting baseballs, softballs and the like. [0002]
  • 2. Description of the Prior Art [0003]
  • A bat to the baseball (softball) games, in addition to the skills of the players, is a key for getting scores; excellent shows can possibly be developed when there are good skills and good bats. [0004]
  • Conventional bats include wooden and aluminum bats etc. A wooden bat is solid and therefore is lacking of vibration absorbency and rebound capability, and is subjected to breaking by overlarge contact force therewith. [0005]
  • An aluminum bat is uneasy to be broken as compared with the wooden bat; it still has the probability to be improved for getting better hitting power though. [0006]
  • A gradual improving mode is to add special material in a bat to increase the performance of the bat. For example, solid cork can be added in the interior of the hitting area of the bat, as shown in FIG. 1; however, bouncing capability thereof is not good although it is capable to absorb the vibrations. Thus, there has been a way to make a hollow annular member of carbon fiber material and place it inside of the inner wall of the hitting area of a bat or by foaming of solid PU in the entire hollow interior of the bat. However, adding the foamed solid PU can have the absorbing capability but have no bouncing capability; and on the contrary, carbon fiber material can have the absorbing capability but can also absorb the bouncing force; thereby, the function can be developed from them is limited. [0007]
  • Accordingly, bats made of various materials still have their own defects; the added interior material for the bats can increase parts of their functions, these are very limited though. In view that the conventional bats still need improvement in their batting effect, the inventor of the present invention provides a novel bat structure after study and improvement. [0008]
  • SUMMARY OF THE INVENTION
  • The primary object of the present invention is to provide an improved bat structure of which the interior space is placed therein at least a PU casting hi-rebound annular hollow member. By virtue that PU has the characteristics of good resilience, high durability and uneasiness of deformation, it can provide rebound force generated by absorbing the vibration from impact induced by contact of the ball and the bat to increase hitting power; and after impacting, it can restore its original state. This can even reinforce the bat to make it uneasy to deform. [0009]
  • To get the above stated objects, the improved bat structure of the present invention is comprised of a main body of a bat and at least a PU casting hi-rebound annular hollow member. The main improved characteristic of the present invention is that at least a PU casting hi-rebound annular hollow member is provided in the space interiorly of the inner wall of the hitting area (depending on the length of the hitting area) and clung to the inner wall of the hitting area. The PU casting hi-rebound annular hollow member in the space interiorly of the inner wall of the hitting area can eliminate the vibration induced by collision between a ball and the bat. And the rebound force generated by the instantaneous restoration characteristic of the PU annular hollow member can increase hitting power; the life of the bat can thus be augmented too, and the bat is uneasy to deform after multiple times of hitting. [0010]
  • The present invention will be apparent after reading the detailed description of the preferred embodiment thereof in reference to the accompanying drawings.[0011]
  • BRIEF DESCRIPTION OF THE DRAWINGS
  • FIG. 1 is a perspective view of a conventional bat with corks therein; [0012]
  • FIG. 2 is a perspective view of the present invention; [0013]
  • FIG. 3 is an anatomic perspective view of the present invention; [0014]
  • FIG. 4 is a sectional view of the present invention.[0015]
  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • Referring firstly to FIGS. [0016] 2-4, the improved bat structure of the present invention is comprised of a main body 10 of a bat and at least a PU casting hi-rebound annular hollow member 20, wherein the main body 10 of the bat is further comprised of a hitting area 11, a top cover 12, a handle 13 and a bottom knob 14. A ratchet shaped portion 121 of the top cover 12 can be engaged with in a sealed state with a ratchet shaped portion 101 on the front end of the hitting area 11.
  • The main improved characteristic of the present invention is that, at least a PU casting hi-rebound annular hollow member [0017] 20 is provided in the space interiorly of the inner wall of the hitting area 11 (depending on the length of the hitting area 11) and is clung to therein. In the present embodiment, There are three PU casting hi-rebound annular hollow members 20 provided in the hitting area 11, a gap 15 is provided between every neighboring PU annular hollow members 20. The ratchet shaped portion 121 of the top cover 12 can be engaged with the ratchet shaped portion 101 on the front end of the hitting area 11. With the above stated features of the structure of the bat, the vibration induced by collision of a ball with the bat can be eliminated, and the PU material can restore its original shape very fast; this can provide additional hitting force by rebound of the bat. In comparison with a conventional bat thereby, the present invention is provided with both the vibration absorbing and rebound capacities to thereby provide players a bat structure with better effects.
  • In conclusion, the present invention can achieve the expected objects, and thereby can provide an improved structure of bat with improved effects; it really has industrial value. [0018]
  • My invention may assume numerous forms and is to be construed as including all modifications and variations falling within the scope of the appended claims. [0019]
