ABSTRACT:
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
U.S. Pat. No. 4,486,016 to Rubin discloses a typical punching bag support including a flexible support rod having a lower portion engaged into a base support and detachably secured to the base support with fasteners. The support rod may not be easily bent during punching operations.
U.S. Pat. No. 5,330,403 to Kuo discloses another punching device including a support rod having a lower portion squeezed and engaged into a base support, and a spring engaged on the squeezed portion of the support rod for forming a flexible punching device. The spring may not be coupled between the support rod and the base without the squeezed portion of the support rod, and the squeezed portion of the support rod may be easily broken while or after punching.
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 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.
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 structure for facilitating the punching or boxing exercises.
The other objective of the present invention is to provide a punching aid 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 device, and means for securing the flexible device between the base and the column to provide a flexibility to the column relative to the base.
The flexible device includes a lower portion and an upper portion, the securing means includes means for fastening the lower portion of the flexible device to the base and means for fastening the upper portion of the flexible device to the column. The pad may be adjusted relative to the column according to the sizes of the users.
The flexible device includes a first end, the securing means includes a first coupler provided on the first end of the flexible device, a second coupler provided on the base, and means for locking the second coupler and the first coupler together. The second coupler is a stud extended from the base and having a groove formed therein, the first coupler includes a hole formed therein for receiving the stud of the base. The locking means includes a projection extended inward of the hole of the first coupler and engaged into the groove of the stud. The stud further includes a lock slot formed therein and communicating with the groove of the stud for receiving the projection of the first coupler.
The locking means includes a fastener engaged through the second coupler and the first coupler to secure the second coupler and the first coupler together. The first coupler includes a protrusion extended therefrom and engaged into the first end of the flexible device. The first coupler includes a disc secured on the protrusion and engaged in the first end of the flexible device. The disc includes at least one opening formed therein for receiving a material for forming the flexible device.
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.
