Abstract
A bowling pin includes a bar secured on top of a core for forming a neck portion of the bowling pin, and a reinforcing rod engaged in the core and the bare for reinforcing the core and the bar. The bar may include a projection engaged into the core for solidly securing the bar to the core. The reinforcing rod may include an outer thread for threading to the core. One or more outer panels may be engaged around the core and around a portion of the bar for solidly securing the bar to the core. An outer cloth layer may be engaged around the outer panels for reinforcing the outer panels.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to a bowling pin, and more particularly to a bowling pin including a reinforcing structure.




2. Description of the Prior Art




Typical bowling pins are required to be stricken by the bowling balls, and are thus required to be made of stronger wood materials, such as the wood materials of the maple trees. As shown in

FIG. 4

, illustrated is a typical bowling pin made of such as the maple wood material. The bowling pin is directly machined or manufactured from a maple wood log material, by such as the lathing machines. However, a large portion of the maple wood material should be cut off before the bowling pin may be formed or produced. In addition, the neck portion of the bowling pin will become the weakest portion that may be easily broken. Furthermore, it has become more and more difficult to obtain the maple wood materials.




The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional bowling pins.




SUMMARY OF THE INVENTION




The primary objective of the present invention is to provide a bowling pin including a reinforcing structure for increasing the striking resistive effect to the bowling pin and for increasing the working life to the bowling pin.




The other objective of the present invention is to provide a bowling pin made of less wood material and made of less maple wood material.




In accordance with one aspect of the invention, there is provided a bowling pin comprising a core, a bar secured on top of the core for forming a neck portion of the bowling pin, and a reinforcing rod engaged in the core and the bare for reinforcing the core and the bar.




The core includes a recess formed therein, the bar includes a projection extended therefrom and engaged into the recess of the core for solidly securing the bar to the core.




The core includes a screw hole formed therein, the reinforcing rod includes an outer thread for threading to the screw hole of the core and for solidly securing the reinforcing rod and the bar to the core.




One or more outer panels may further be provided and engaged around the core, and preferably engaged around a portion of the bar for solidly securing the bar to the core.




An outer cloth layer or such as the woven or non-woven cloth material may further be provided and engaged around the outer panels for reinforcing the outer panels.




Further objectives and advantages of the present invention will become apparent from a careful reading of a detailed description provided hereinbelow, with appropriate reference to accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




Referring to the drawings, and initially to

FIGS. 1 and 2

, a bowling pin in accordance with the present invention comprises a core


10


including a recess


11


formed in the upper portion thereof, and including a hole, such as a screw hole


12


formed in the upper portion thereof and communicating with the recess


11


thereof. It is preferable that the recess


11


is formed across the upper portion of the core


10


and has two open ends. A bar


14


includes a projection


16


extended downward therefrom and engaged into the recess


11


of the core


10


. The projection


16


of the bar


14


may be secured to the core


10


with such as a force-fitted engagement, an adhesive material, or by fasteners, or the like, for solidly securing the bar


14


to the core


10


and for preventing the bar


14


from being easily broken relative to the core


10


.




A reinforcing rod


17


has one end, such as the upper end engaged in the bar


14


, and has the other end, such as the lower end engaged in the core


10


. The rod


17


may include an outer thread


18


formed in the lower portion thereof for threading with the inner thread or the screw hole


12


of the core


10


, and for further solidly securing the bar


14


to the core


10


. The rod


17


may be made of stronger wood materials, metal materials, fiber reinforcing materials, or the like, for increasing the bending strength of the neck portion of the bowling pin. The bar


14


will be machined into the neck portion of the bowling pin and is preferably made of maple wood material has has a better anti-striking effect. The core


10


may be made of the other materials, or wood materials, or made of the waste wood materials, for environment protection purposes.




A number of outer panels


19


are further provided and engaged onto the outer peripheral portion of the core


10


, and preferably engaged onto a portion of the outer peripheral portion of the bar


14


, best shown in FIG.


3


. The outer panels


19


are preferably made of thin layer wood material, and include different height, for allowing the outer panels


19


to be engaged onto or secured onto the outer peripheral portion of the core


10


and the bar


14


, by such as the adhesive materials, in a shape close to an elliptical shape. The outer panels


19


will then be machined into the elliptical lower portion of the bowling pin. The outer panels


19


may also be made of the other materials, or wood materials, or made of the waste wood materials, for environment protection purposes.




A woven or non-woven outer cover layer


20


may further be provided and engaged around the lower portion of the bowling pin or around the outer panels


19


. The outer panels


19


may be made of wood materials and may thus include a weak anti-striking strength. primarily due to the wood veins of the wood materials. The outer cover layer


20


of woven or non-woven cloth materials may be secured onto the outer peripheral portion of the outer panels


19


with resins or with the other adhesive materials, for forming a smooth outer peripheral surface and for reinforcing the outer panels


19


.




It is to be noted that the core


10


and the reinforcing rod


17


and the outer panels


19


are not required to be made of maple wood material and may be made of the other wood materials or the other materials, such as the plastic materials, the composite materials, or the like. The bar


14


is preferably made of maple materials, but may also be made of the other wood materials or the other materials, such as the plastic materials, the composite materials, or the like. The rod


17


may reinforcing the bar


14


or the neck portion of the bowling pin, for preventing the neck portion of the bowling pin from being easily broken. The engagement of the outer cover layer


20


onto the outer panels


19


may further reinforcing the outer panels


19


and may increasing the anti-striking strength to the bowling pin.




It is further to be noted that the thin layer outer wood panels


19


may be made or formed to an area or to a shape closer to the final shape of the bowling pin to be formed, such that less wood material will be cut off, and such that less wood material is required for forming the bowling pins.




Accordingly, the bowling pin in accordance with the present invention includes a reinforcing structure for increasing the striking resistive effect to the bowling pin and for increasing the working life to the bowling pin.




Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made by way of example only and that numerous changes in the detailed construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
