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.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1
is a perspective view of a bowling pin in accordance with the present invention;
FIG. 2
is an exploded view of the bowling pin;
FIG. 3
is a cross sectional view illustrating the formation or the manufacturing of the bowling pin; and
FIG. 4
is a perspective view showing the typical bowling pin.
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.
