Abstract

A hitting set that is applicable to bats includes a bat body and a hitting sleeve. The bat body is divided into a handle portion and a hitting portion. The hitting sleeve can be slipped on over the hitting portion. Through the slip-on setting between the hitting sleeve and the hitting portion, micro-gaps are formed between the hitting sleeve and the hitting portion. The invention can be used by setting forth the hitting sleeve to wrap around on the hitting portion. Through the micro-gaps naturally formed between the hitting sleeve and the hitting portion, the impact force generated while the invention hitting a ball can be further absorbed, avoid the force of impact affecting the feel of a batter's grip when hitting a ball, and prevent the force of impact from causing injury to batter's wrist.

Description

    BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • The invention relates to a hitting sleeve that can be slipped on over any types of bat, more specifically, a hitting sleeve using a dual-layer concept that the impact force is absorbed by the first layer of the hitting sleeve so that the batter can have the feel of an excellent shot while hitting the ball and is not subject to the impact force while hitting the ball
  • 2. Description of Related Art
  • Baseball has a long history. Although the hard baseball is the mainstream of the world, nevertheless, taking into account factors of the site, safety, price and availability, most children learn to play the soft baseball first. However, no matter using a soft baseball or hard baseball, when strike of a bat against a ball occurs, it generates a certain impact force. If there is not sufficient protective measures or warm-up exercise prior to engaging the sport, certain sports injury to the body may happen and be hard to prevent.
  • Therefore, how to reduce the impact force to the batter during strike and, at the same time, to sustain the feel of the shot while hitting the ball become an important goal that many sports goods manufacturers set for their research and development of products.
    • SUMMARY OF THE INVENTION
  • Based on the aforementioned subjective, the hitting set that is applicable to bats of the invention comprises a bat body and a hitting sleeve wherein the bat body is divided into a handle portion and a hitting portion and the hitting sleeve is slipped on over the hitting portion. Through the slip-on setting between the hitting sleeve and the hitting portion, micro-gaps are formed between the hitting sleeve and the hitting portion.
  • Moreover, the inner wall of the hitting sleeve can install a plurality of small protruding points to force creating micro-gaps between the hitting sleeve and the hitting portion. These gaps can also be filled with materials that can provide vibration absorption effect, such as colloid and elastomer, to further absorb the impact force.
  • Furthermore, the bat body and the hitting sleeve are preferably made of composite materials, metal materials, plastic materials or wood materials whereas the composite materials are preferably carbon fiber, boron nanofiber, Kevlar, and fiberglass; the metal materials are preferably aluminum alloy, magnesium alloy, titanium alloy, and stainless steel; the wood materials are preferably birch, maple, and bamboo.
  • The key features of the invention are due to the fact that the hitting sleeve is secured over the hitting portion in a wrapping manner so that some gaps may exist in between and these gaps do not affect the tightness of the slip-on setting between the hitting sleeve and the hitting portion. The remaining impact force, which occurs when the bat and the hitting sleeve hit the ball, to be directly transmitted to the bat body and to cause injury to the player's hand can be prevented by these gaps wherein the filled colloid, elastomer and vibration absorption materials (or no materials being added) can help to further absorb the impact force.
  • The above and other objects, features and advantages of the invention will become apparent from the following detailed description taken with the accompanying drawings.
    • BRIEF DESCRIPTION OF THE DRAWINGS
  • FIG. 1 is a perspective schematic diagram of the invention;
  • FIG. 2 is a perspective exploded diagram of the invention;
  • FIG. 3 is a detailed view of the area in circle A in FIG. 1;
  • FIG. 4 is a schematic diagram of a first preferred embodiment of the invention;
  • FIG. 5 is a schematic diagram of a second preferred embodiment of the invention; and
  • FIG. 6 is a comparison table of materials of the invention.
    •  DETAILED DESCRIPTION OF THE INVENTION
  • Referring to FIG. 1, FIG. 2 and FIG. 3, according to the figures, the hitting set that is applicable to bats of the invention comprises a bat body 1 and a hitting sleeve 2, wherein the bat body 1 is divided into a handle portion 11 and a hitting portion 12, and the hitting sleeve 2 is slipped on over the hitting portion 12. Through the slip-on setting between the hitting sleeve 2 and the hitting portion 12, micro-gaps 3 are formed between the hitting sleeve 2 and the hitting portion 12.
  • Moreover, the inner wall of the hitting sleeve 2 can install a plurality of small protruding points 4 to force creating micro-gaps 3 between the hitting sleeve 2 and the hitting portion 12. These gaps 3 can also be filled with materials that can provide vibration absorption effect, such as colloid and elastomer, (or no materials being added) to further absorb the impact force.
  • Furthermore, the bat body 1 is preferably made of composite materials, metal materials, plastic materials or wood materials.
  • Furthermore, the hitting sleeve 2 is preferably made of composite materials, metal materials, plastic materials or wood materials.
  • Next, the hitting sleeve 2 disclosed in the invention is made of composite materials, metal materials, plastic materials or wood materials to guarantee the strength, coefficient of rebound, the hand feel while striking a ball. In addition, the hitting sleeve 2 and the hitting portion 12 are bound to each other through in a wrapping manner. Therefore, there are many micro-gaps 3 being created between the hitting sleeve 2 and the hitting portion 12. Or, the inner wall of the hitting sleeve 2 is installed with a plurality of small protruding points 4 to force creating micro-gaps 3 between the hitting sleeve 2 and the hitting portion 12 (the size of the gap 3 can be adjusted by the density or size of the protruding points). These gaps 3 do not affect the tightness of the slip-on setting between the hitting sleeve 2 and the hitting portion 12.
  • Accordingly, the invention not only can apply the slip-on setting to prevent the impact force, generated when the ball hits the hitting sleeve 2, from effectively being transmitted but also includes the gaps 3 that provide the effect of reducing the impact force being transmitted to the handle portion 11. Therefore, the player will not be interfered by the vibration and the sport injury, which the impact force may cause, to the player can be prevented. Besides, these gaps 3 can be filled with colloid, elastomer and vibration absorption materials to further absorb the impact force (or no materials are added).
  • Referring to FIG. 4 and FIG. 5, according to the figures, when strike of the bat body 1 against a ball 3 occurs, it generates a certain impact force. Using the hitting sleeve 2, the impact of vibration can be absorbed effectively (as shown in FIG. 5). In addition, the hitting sleeve 2 and the bat body 1 are bound to each other through in a wrapping manner. Therefore, the hitting sleeve can be secured to different bats based on batter's needs under different circumstances (for example, a heavier hitting sleeve 2 can be bound to a bat for the use of a long hit).
  • Referring to FIG. 6 along with FIG. 5, in FIG. 6, there is a comparison table of materials 4 of the invention. The bat body 1 and the hitting sleeve 2 described in the invention can be made of the same material or different materials accordingly. For example, a bat body 1 made of wood material is wrapped with a hitting sleeve 2 made of composite materials to give the batter a better feel of the strike. Besides, the hitting sleeve 2 can absorb vibration effectively. Using softer composite materials (such as carbon fiber, boron nanofiber, etc.), the stagnant duration of the ball in contact of the hitting sleeve 2 can be prolonged, as a result, giving the batter sufficient time to control the ball direction upon striking the ball, wherein the composite materials are preferably carbon fiber, boron nanofiber, Kevlar, fiberglass; the metal materials are preferably aluminum alloy, magnesium alloy, titanium alloy, stainless steel; the wood materials are preferably birch, maple, bamboo.
  • While the invention has been described in terms of preferred embodiments, those skilled in the art will recognize that the invention can be practiced with modifications within the spirit and scope of the appended claims.
