Abstract
Apparatus to add weight to an athletic ball striking bat, having a taper along the bat length, comprising in combination a oleeve sized to extend about the bat at the taper location, the sleeve having associated retention means to engage the bat at a zone along said taper to resist lengthwise removal of the sleeve off the bat during bat swinging, a weight or weights carried by the sleeve.
Description
- This application is a continuation-in-part of Ser. No. 10/262,734 filed Oct. 1, 2002.
- This invention relates generally to swinging of ball strikers as, for example, baseball bats. More specifically, it it related to the field of practice or warm-up swinging of such strikers or bats having weight added to them.
- When athletes who handle ball strikers warm-up, or train, they commonly use two strikers, and swing them in unison a few times to loosen muscles. Holding and swinging two strikers is awkward, uncomfortable, and does not achieve the right feel, needed as by gripping and swinging only one striker but one striker does not achieve additional weight as can be provided by two strikers. There is need to overcome this dilemma, in a simple, effective and efficient manner, as is now provided by the present invention. In a similar manner, there is need to provide improvements as respects devices for adding weight to ball strikers such as baseball bats, for example.
- There is also need for a weight holding device that can be easily attached to and removed from a bat and which positively and safely retains the added weight to the bat.
- It is a major object of the invention to provide a simple and effective device or apparatus that meets the above need. Basically, the device is adapted for use in a ball striker or bat having a taper or tapered surface, along its length, and includes:
- a) a sleeve sized to extend about the bat at the taper location;
- b) the sleeve having associated retention means to operatively engage the bat in a zone along said taper to resist lengthwise removal of the sleeve off the bat during bat swinging,
- c) a weight or weights carried by the sleeve.
- As will be seen, the weight or weights are typically carried at a location or locations proximate to the ball striking zone; and the retention means is spaced from the weight or weights, and has an arcuate interior surface to arcuately engage the bat at arcuately spaced locations.
- It is a further object to enable bat reception through the sleeve, so that the bat handle projects from the sleeve, the engaged zone of the bat typically located between the handle and weight or weights. The latter may be located in a pocket or pockets formed by or attached to the sleeve.
