BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to a punching aid, and more particularly to a punching aid for home use.




2. Description of the Prior Art




Various kinds of punching aids or striking devices have been developed. U.S. Pat. No. 2,085,161 to Kraus, U.S. Pat. No. 2,913,245 to Landis, U.S. Pat. No. 4,486,016 to Rubin, U.S. Pat. No. 4,662,630 to Dignard et al., U.S. Pat. No. 5,330,403 to Kuo U.S. Pat. No. 5,415,552 to Harmon et al., U.S. Pat. No. 5,921,895 to Lynch et al., all disclose a typical punching aid or striking device having a bag coupled to a support with one or more flexible or helical spring or metal members. The spring or metal support members may not be easily bent during punching operations.




U.S. Pat. No. 5,624,358 to Hestilow discloses a further punching device including a column extended upward from a pedestal and formed integral as an integral one piece unit. The column is solidly secured to or extended from the pedestal and is made of plastic material that are not flexible, such that the column may not be easily bent while punching. In addition, the punching device occupies a great volume which is adverse for transportation and carrying purposes.




None of the prior striking devices or punching aids suggest to provide a flexible rubber pillar coupled between the base and the pad.




The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional punching or boxing aids.




SUMMARY OF THE INVENTION




The primary objective of the present invention is to provide a punching aid including a flexible rubber pillar for facilitating the punching or boxing exercises and including a detachable structure for allowing the punching aid to be disassembled and packaged to a compact configuration.




In accordance with one aspect of the invention, there is provided a punching aid comprising a base, a column provided above the base, a pad attached onto the column, a flexible rubber pillar, and means for securing the flexible rubber pillar between the base and the column to provide a flexibility to the column relative to the base. The pillar is made of rubber material for providing an excellent resilience to the column and the pad relative to the base.




The flexible rubber pillar includes a first end, the securing means includes a first coupler provided on the first end of the flexible rubber pillar, a second coupler provided on the base, and means for locking the second coupler and the first coupler together.




The first coupler includes a protrusion engaged into the first end of the flexible rubber pillar, and includes a disc secured on the protrusion and engaged in the first end of the flexible rubber pillar.




The flexible rubber pillar includes an upper peripheral recess and a lower peripheral recess formed therein and includes a middle portion having a peripheral bulge formed thereon. The peripheral recesses of the flexible rubber pillar are curved. The peripheral bulge of the flexible rubber pillar is convex.




The flexible rubber pillar includes at least one peripheral rib formed between the peripheral bulge and the upper peripheral recess of the flexible rubber pillar, and includes at least one peripheral rib formed between the peripheral bulge and the lower peripheral recess of the flexible rubber pillar and includes at least one longitudinal rib formed thereon for increasing a strength of the flexible rubber pillar.




A shielding or covering sleeve device is further provided and attached onto the flexible rubber pillar for shielding the flexible rubber pillar and for preventing the users and the children from being hurt by the flexible rubber pillar.

The above described structure has been described in the co-pending U.S. pat. application Ser. No. 09/432,065, filed on Oct. 27, 1999, and the co-pending U.S. patent application Ser. No. 09/479,178, filed on Jan. 5, 2000, which are taken as the references for the present invention.




The most important characteristic for the punching aid is that the flexible pillar


40


is made of rubber or synthetic materials and has the upper and the lower portions coupled to the column


20


and the base


10


respectively. None of the arts may provide a flexible rubber pillar


40


directly coupled to the base


10


and the column


20


. Although the flexible pillar


40


is shown to be coupled to the base


10


and the column


20


with the engagement between the stud and the coupler, the flexible rubber pillar


40


may also be directly coupled to the base and the column with fasteners without the studs and the couplers. The typical spring members may not be easily coupled between the base and the column. The column


20


and the pad


30


and/or the flexible pillar


40


may be detached or disengaged from the base


10


such that the column of the punching aid may be greatly decreased for facilitating the storing and the transportation thereof.




For increasing the flexibility of the pillar


40


, the flexible rubber pillar


40


includes an upper portion having a peripheral curved recess


41


formed therein, and includes a lower portion having a peripheral curved or concave recess


41


formed therein, and includes a middle portion having a convex or an outwardly curved peripheral bulge


80


formed thereon, for forming a wavy shape and for increasing the flexibility of the pillar


40


. The pillar


40


further includes one or more peripheral ribs


48


formed thereon, preferably formed between the peripheral recesses


41


and the peripheral bulge


80


, and includes one or more longitudinal ribs


49


formed thereon and intersecting with the ribs


48


in order to form a spider-rib structure and in order to increase the strength of the flexible pillar


40


.




As shown in

FIG. 5

, one of the couplers


420


secured to the flexible pillar


40


may be a stud-shaped coupler


420


similar to that (


14


,


21


) of the base


10


and the column


20


. The column


20


or the base


10


may include a socket


100


similar to the couplers


42


as shown in

FIGS. 1-3

and having a hole


19


formed therein for receiving the stud-shaped coupler


420


which may also be secured to the socket


100


with a projection-lock slot engagement and/or a locking pin. The socket or the stud


21


of the column


20


may be directly secured to the stud or the socket


15


of the base


10


without the flexible pillar


40


for decreasing the height of the punching aid and for being easily stricken by the children.




As best shown in

FIG. 3

, a flexible or protective sleeve


70


, such as a bellows type sleeve, is further provided and engaged onto the flexible pillar


40


for shielding and protecting the flexible pillar


40


, particularly for shielding the peripheral ribs


48


and the longitudinal ribs


49


of the flexible pillar


40


. The protective sleeve


70


may include the upper and the lower portions secured to the couplers


42


with the fastener pins


50


, for example.




Accordingly, the punching aid in accordance with the present invention includes a flexible rubber pillar for facilitating the punching or boxing exercises, and includes a detachable structure for allowing the punching aid to be disassembled and packaged to a compact configuration.
