Punching bag support apparatus

A punching bag support apparatus is provided comprising a mounting plate, a pivot shaft, an elongated rail rotably attached to the pivot shaft, and a trolley frame slidably riding on and supported by the rail, thereby enabling a punching bag supported on the trolley frame to be moved rotationally about the central vertical axis of the support apparatus as well as able to be linearly moved through the central vertical axis of the support apparatus.

BACKGROUND OF INVENTION 
This invention relates generally to the art of support apparatuses, and 
more particularly to the art of a support apparatus for a punching bag. 
Various support devices exist within the prior art. It has been desirable 
to provide such support apparatuses which are capable of supporting a 
punching bag so that a person can practice on the punching bag by himself 
or with the aid of a trainer. It is even more desirable, however, to 
provide a punching bag support apparatus which is moveable in order to 
provide a person using the bag with a more realistic workout. U.S. Pat. 
No. 4,911,428 discloses a support for a punching bag comprising a 
horizontally disposed beam supported from an overhead support for rotation 
about a vertical axis with a punching bag supported at one end of the beam 
and an adjustable caster wheel at the other end of the beam for rolling 
engagement with the overhead support, thereby enabling the punching bag to 
move in a circle about the rotational axis of the beam, either clockwise 
or counterclockwise. While this prior art apparatus functions well for its 
intended purpose, room for improvement exists. 
SUMMARY OF THE INVENTION 
It is thus an object of this invention to provide a novel punching bag 
support apparatus. 
It is a further object of this invention to provide such a novel punching 
bag support apparatus which enables a punching bag supported thereon to be 
rotationally moveable about a central vertical axis of the support 
apparatus. 
It is still a further object of this invention to provide such a novel 
punching bag support apparatus which enables a punching bag supported 
thereon to be linearly moveable through a central vertical axis of the 
support apparatus. 
These as well as other objects are accomplished by a punching bag support 
apparatus comprising a mounting plate, a pivot shaft extending from the 
mounting plate, an elongated rail rotably attached to an end of the pivot 
shaft, a trolley frame slidably riding on and supported by the elongated 
rail, and means for supporting a punching bag included on the trolley 
frame.

DETAILED DESCRIPTION 
In accordance with this invention, it has been found that a novel punching 
bag support apparatus can be provided. It has also been found that such a 
novel punching bag support apparatus can be provided which enables a 
punching bag supported thereon to be rotationally moveable about a central 
vertical axis of the support apparatus. It has further been found that 
such a novel punching bag support apparatus can be provided which enables 
a punching bag supported thereon to be linearly moveable through a central 
vertical axis of the support apparatus. 
Various other advantages and features will become apparent from a reading 
of the following description given with reference to the various figures 
of drawings. 
FIG. 1 of the drawings is a perspective view of the punching bag support 
apparatus 10. As illustrated, punching bag support apparatus 10 comprises 
a mounting plate 12 which has a pivot shaft 14 extending therefrom. A 
collar 32, used in the preferred embodiment, surrounds the pivot shaft 14 
(seen in FIG. 2) which extends from the mounting plate 12. Collar 32 
secures elongated rail 18 to the pivot shaft 14 such that elongated rail 
18 is rotationally moveable about pivot shaft 14, which is the central 
vertical axis of punching bag support apparatus 10. 
Elongated rail 18 is in a horizontal position generally parallel to 
mounting plate 12. A trolley frame 20 slidably rides on and is supported 
by elongated rail 18. Trolley frame 20 also includes means for supporting 
22 a punching bag 24. Also seen in FIG. 1 are tension rods 26 which 
include turnbuckles 28. Tension rods 26 extend from the top of collar 32 
near mounting plate 12 to anchors 30 formed on the ends of elongated rail 
18 in order to provide stability to elongated rail 18 when punching bag 24 
is moved across elongated rail 18. Trolley frame 20 therefore allows 
punching bag 24 to be linearly moveable along elongated rail 18 through 
the central vertical axis of punching bag support apparatus 10. 
FIG. 2 is a fragmentary perspective view of the punching bag support 
apparatus 10. Mounting plate 12 is shown as being attached to a ceiling 
13. Pivot shaft 14 extends generally from the center of mounting plate 12, 
and elongated rail 18 is rotably attached to pivot shaft 14 by a collar 32 
in the preferred embodiment. In this preferred embodiment, bearings 34 are 
positioned between collar 32 and pivot shaft 14 in order that collar 32 
can rotate around pivot shaft 14. Collar 32 surrounds pivot shaft 14 and 
attaches to elongated rail 18 to secure elongated rail 18 to pivot shaft 
14. By this attachment of elongated rail 18 to pivot shaft 14, elongated 
rail 18 is rotationally moveable, either clockwise or counterclockwise, 
about pivot shaft 14 which is the central vertical axis of punching bag 
support apparatus 10. 
FIG. 2 also illustrates tension rods 36 which extend from anchors 30 on the 
ends of elongated rail 18 to near the top of collar 32. Tension rods 36 
provide stability to elongated rail 18 when a punching bag 24 is moved 
along elongated rail 18. Turnbuckles 40 are used with tension rods 36 in 
the preferred embodiment for adjustment of tension rods 36. 
Trolley frame 20 rides on and is supported by elongated rail 18 so that 
trolley frame 20 can slide linearly along elongated rail 18. Rollers 42 
are illustrated in phantom to enable trolley frame 20 to slidably ride 
upon elongated rail 18. Trolley frame 20 also includes means for 
supporting a punching bag which may include a compression spring such as 
spring 44 to provide greater stability to punching bag 24. An adjustable 
braking means 46 for controlling trolley frame 20 is also seen in partial 
phantom in FIG. 2. Adjustable braking means 46 comprises a knob 48 which 
can be adjusted to force roller 50 against elongated rail 18. In this 
manner, the linear movement of trolley frame 20 along elongated rail 18 
can be controlled and adjusted as desired. 
Also illustrated in FIG. 2 is an adjustable rotational breaking means 51 to 
control the rotation of elongated rail 18 around pivot shaft 14. 
Adjustable rotational braking means 51 comprises a pad 53 which is pressed 
upward against elongated rail 18 and surrounds pivot shaft 14. Ring 52 
matingly engages the bottom of pivot shaft 14 and can be adjusted to apply 
more or less pressure to force pad 53 against elongated rail 18. Screw 54 
can be used for greater precision in adjusting rotational braking means 
51. In the preferred embodiment adjustable rotational braking means 51, 
through adjustment of ring 52 and screw 54, is used to control the 
rotation of elongated rail 18 and collar 32 about pivot shaft 14. 
FIG. 3 is a cross section view along line 3--3 of FIG. 2 illustrating the 
preferred structure of punching bag support apparatus 10. In the preferred 
embodiment, elongated rail 18 has an inverted generally U-shaped cross 
section with outwardly directed flanges 19 formed on the edges thereof. 
Trolley frame 20 is illustrated as including two pairs of rollers 42 which 
ride against the top side of elongated rail 18 and enable trolley frame 20 
to slidably ride along flanges 19 and against elongated rail 19 while 
being supported by elongated rail 18. FIG. 3 also illustrates adjustable 
braking means 46 which can be used to control the movement of trolley 
frame 20 along elongated rail 18. Adjustable braking means 46 comprises a 
knob 48 which can be adjusted to force roller 50 against flange 19 of 
elongated rail 18. Trolley frame 20 also includes means for supporting 
punching bag 24, such means including chain 56 and spring 44. 
As illustrated in FIG. 3, trolley frame 20 supporting punching bag 24 
therefore slidably rides along elongated rail 18 and can be linearly moved 
along the length of elongated rail 18 as desired. During a boxing workout, 
a trainer can push punching bag 24 along the length of elongated rail 18 
towards a boxer. As illustrated in FIGS. 1 and 2 of the drawings, it is 
also seen that punching bag 24 can be moved clockwise or counterclockwise 
about pivot shaft 14. The combination of these two movements, the 
clockwise or counterclockwise movement and the linear movement along 
elongated rail 18, enables a trainer to more realistically work with a 
boxer and even allows a boxer wishing to work out by himself to have a 
more realistic and responsive workout with punching bag 24. 
It is thus seen that the present invention provides a novel punching bag 
support apparatus. It is also seen that the present invention provides 
such a novel punching bag support apparatus which enables a punching bag 
supported thereon to be rotationally moveable about a central vertical 
axis of the support apparatus. It is still further seen that such a novel 
punching bag support apparatus is provided which enables a punching bag 
supported thereon to be linearly moveable through a central vertical axis 
of the support apparatus. Many variations are apparent to those of skill 
in the art, and such variations are embodied within the spirit and scope 
of the present invention as measured by the following appended claims.
