The invention relates to punch bag support assemblies. As used herein, the term punch bag covers other training devices which are intended to be struck by the user, an example being a torso pad.
Traditionally, punch bags used for the training of athletes, including boxers, have comprised a stationary bag suspended by a strap and mounted on a spring or between two straps with inherent elasticity. The punch bag returns to a position in front of the boxer after he has hit it. Such a comparatively stationary punch bag does not provide a realistic workout. In practice, a real opponent would move about much more in relation to the subject boxer. U.S. Pat. No. 5,048,822 discloses a punch bag support assembly including a track from which the punch bag may be suspended, a drive for moving the punch bag along the track, and control apparatus for controlling the speed and direction of movement along the track. GB2434112 discloses a punch bag support assembly which includes a linear mechanism which supports the punch bag and allows its linear movement along a given length of track. First and second rotary mechanisms enable rotation about first and second axes respectively.
EP2437860 discloses a punch bag support assembly having a base, a first movable disc rotatably connected to the base and a second movable disc rotatably connected to the first movable disc. This arrangement is claimed to give rise to an unpredictable movement pattern for a punch bag mounted on the support assembly.
According to the present invention, there is provided a
punch bag support assembly comprising:
Preferably, the or each urging means is a spring.
Preferably, the assembly is provided with at least one damper. The or each damper may be, for instance, an adjustable spring.
Preferably, a damper is provided at the pivotal connection between the mounting unit and the first elongate arm and/or at the pivotal connection between the first elongate arm and the second elongate arm.
Preferably, at least one connection comprises a bearing assembly.
Preferably, the mounting means comprises a spring.
Preferably, the mounting unit comprises a plate provided with means whereby the assembly may be attached to a suitable support structure.
Preferably, the assembly comprises means for locking the two arms together.
Alternatively or additionally, the mounting unit preferably comprises mean whereby a punch bag may be suspended directly from the mounting unit.
Preferably, the or each arm is a hollow, rectangular cross-section element.
Preferably, the arms are slightly curved.
Preferably, bearings are provided between the mounting unit and the first arm and between the first arm and the second arm.
Preferably, the bearings are located within bearing housings within each of which is mounted a spring arrangement provided with means for causing the movement of the punch bag to become jerky.
The present invention also provides a method of providing punch bag training comprising providing a punch bag support assembly according to any of the preceding claims, attaching a punch bag to said punch bag support assembly whereby striking the punch bag will cause it to follow a complex path of movement due to the connections between the mounting unit and the first elongate arm and between the first elongate arm and the second elongate arm.
The accompanying drawings are as follows:
Embodiments of the present invention will now be described, by way of examples only, with reference to the accompanying drawings.
Referring to
The punch bag may be suspended from the apparatus 1 by a fixed connection or by one that provides twist and snagging reduction by the use of a swivel hook holder. Accordingly, the assembly may be operated in an entirely stationery mode, in a swivel mode and in a manner allowing relative pivotal movement between the arms, that is to say, encompassing at least three functions provided by a single assembly.

In an alternative embodiment shown in
Referring in more detail to
An adjustable nylon damper screw 113 extends into bearing housing 109, the end of which is received by a damper screw receiver located within housing 109. Damper screw 113 is capable of being screwed into a chosen degree of engagement with bolt 105 to effect a desired degree of damping of the rotation of bearing housing 109 about bolt 105.
Extending horizontally from bearing housing 109 is a hollow primary arm 117 which is rectangular in cross section and which is provided at its end remote from housing 109 with a bearing housing 121 which includes upper and lower bearing components 125 and 127 and a bolt 123 extending axially through these components. Connected to bearing housing 121, at a position below that of primary arm 117, is a secondary arm 129 which extends horizontally in a plane below that of primary arm 117.
Provided within bearing housing 121 is a spring arrangement such as that illustrated as 163 in
Secondary arm 129 has, extending vertically therethrough at a mid-position therealong, a locking screw hole 132 within which a locking screw 131 is located. Locking screw 131 may be turned so that its shank extends through screw hole 132 into engagement with a locking screw receptor 119 located on the underside of primary arm 119 in order to prevent relative rotational movement between the primary and secondary arms 117 and 129.
The end of secondary arm 129 is provided with a cap end 135.
Extending downwardly from that end of secondary arm 129 remote from bearing housing 121 is a directional spring (not shown) to which is attached a bolt hook 133 whereby a punch bag or the like may be attached to the support assembly.
The damper screws may be made of any suitable material including metal and plastics. Rod or bolt 105 may be welded to fixing plate 101 and grub screws used to secure the assembly in place.
The spring 153 in the middle of tube 151 results in the motion of the torso pad being highly random. This, together the effect of the spring arrangement 163 (
Referring to
The other end of primary arm 201 is pivotally attached to a secondary arm 213 by housing components 215 and 217 which together house a shaft 219 a spring 221, a bearing 210 and a bearing retaining plate 223. Spring 221 is a flat stainless steel coil spring having radially directed ends which engage in respective slots in shaft 219 and housing 217. Extending through arm 213 about two thirds of the way along the arm from its pivotally attached end is locking bolt arrangement 225 which allows the two arms 201 and 203 to be locked together, if desired. Arrangement 225 includes a knob 227, a locking bolt 229, a locking bolt 231 and a spring 233.
At the free end 235 of secondary arm 213 there is located an attachment port bushing 237, allowing attachment of a punch bag or the like, and an end cap 239.
It will be appreciated that the invention can be embodied in different ways. For instance, the secondary arm may be provided with two further holes for the spring loaded pad to be moved closer to the centre of the jointed connection to the primary arm. This will close down the distance to the target pad and also close down the overall rotational difference of the pad. In effect, this brings the sparring distance closer to the centre of the fighting distance in relation to the pad. Overall, this simulates a fighter fighting on the counter at long distance as well as a fighter getting in close.
An extra damping thumb screw can be added to the secondary arm so as to complement the secondary arm distance change with the two extra hole fixing points for a fighter that likes to fight close in. This will result in different speeds of both arms at different adjustments from length to speed as each arm would be unique in rotation from primary to secondary.
In these ways the behaviour of the product is much more unpredictable. The product can be custom made to a different class of sparring while retaining its unique randomised action.
