Title

"Exercise Device"

Technical Field

[0001] The invention relates to an exercise device for use in training and in the building and/or improving of general body strength, particularly upper body strength. It also relates to methods of using the exercise device. The device is especially useful in multidisciplinary and compound training.

[0002] Throughout the specification, unless the context requires otherwise, the word "comprise" or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated integer or group of integers but not the exclusion of any other integer or group of integers.

Background Art

[0003] The following discussion of the background art is intended to facilitate an understanding of the present invention only. It should be appreciated that the discussion is not an acknowledgement or admission that any of the material referred to was part of the common general knowledge as at the priority date of the application.

[0004] Exercise devices for improving general fitness and in particular upper body fitness are well known in the art and cover a wide range of devices. These can include multicomponent weightlifting devices typically employing counter-balanced weights and pulley mechanisms as used in fitness centres.

[0005] Simpler devices such as weight training devices are also commonly used in the fitness industry. Devices such as barbells, dumbbells, weight balls (such as medicine balls, slam balls etc) may all be used in a variety of ways for an individual to exercise specific muscles or muscle groups and improve upper body strength.

[0006] Many of the weight devices are fixed weighted, particularly barbells, dumbbells and weight training balls, meaning they are one weight only, although able to be varied, and typically for a particular exercise regime.

[0007] Alternative devices include more cardio-based exercise devices such as battling ropes. Battling ropes can be provided as single or two rope combinations and are of sufficient innate weight that when used result in predominantly cardio based exercise, although other benefits such as upper body strength are also improved. These ropes can be affixed to a wall or floor or can be held by a second person. The idea is to cause the ropes to move in an undulating fashion, the method improving both upper and lower body strength and improving cardio-vascular fitness.

[0008] However, the aforementioned devices, especially battling ropes, have numerous disadvantages including, the need for ample room to use them as they require a large area to train, the need for fixing points to affix them at one end, they are hard to manoeuvre, are very noisy, require supervision, and are costly.

[0009] It is an aim of the present invention to provide an improved exercise device that achieves the positive outcomes of improved body power, strength and fitness, preferably improved cardio-vascular health and at the same time overcoming some of the disadvantages of existing exercise devices.

Description of Best Mode and Embodiments

[0093] The following description is made with reference to a best mode for carrying out the invention and several specific embodiments of the best mode, as well as another mode and specific embodiments thereof. It should be noted that in the description of different embodiments the same reference numerals are used to denote the same or similar features.

[0094] As noted above there are numerous types of exercise devices and in this context battling ropes may be the most analogous device to which use of the batons of the present disclosure can be compared and contrasted.

[0095] Figure 1 illustrates a standard use of battling ropes 1 by a person 3. These ropes 1 can be either free standing, that is they are not attached to anything, and can lie directly on the ground; or can be held by another person at the non-use end and due to their weight undulate with use. This can have disadvantages in that whilst these types of ropes are traditionally very heavy, they can in fact move during use and require a substantial amount of room to be used. Even where the ropes are secured to a floor or wall mounting they pose a hazard to other persons. They are also very noisy in use and are cumbersome to work with and store.

[0096] In contrast the exercise device of the invention as described in the following embodiments can be used without the aforementioned disadvantages.

[0097] The best mode and preferred embodiment of the invention is shown in Figure 2 being used to perform similar exercises to those used with the battling ropes 1 shown in Figure 1. In this instance the user 3 is using a pair of exercise devices 10 in accordance with a first embodiment to undertake the same or a similar exercise as illustrated in Figure 1. The use of one or more of the exercise devices alleviates the need for cumbersome ropes and overcomes the issues of space requirements and being a hazard to others. Further the baton form of each exercise device 10 of the present embodiment allows for a far greater diversity of exercise regimes.

[0098] In the drawings, three types of batons are shown that are based upon the principles of the best mode and preferred embodiment of the invention:

(i) Figures 3 to 11 show a baton formed with a detachable weight assembly comprising different weight combinations of four 100 gram weights;

(ii) Figures 12 to 17 show a baton formed with a fixed weight assembly for housing higher weights comprising different weight combinations of three 300 gram weights; and

(iii) Figures 18 to 21 show a baton formed with a fixed weight assembly for housing lower weights comprising different weight combinations of four 100 gram weights.

[0099] In each of the three types of batons, an exercise device 10 generally comprises a weighted baton 20, a distal weighted end 25, a proximal support end and an arm band connector 100.

[0100] The proximal support end 30 that is near to a person using the exercise device 10 has an arm supporting portion 40 and handle portion 45. The handle portion 45 is intermediate of the baton 20 and is axially aligned with: (i) the arm supporting portion 40 at a proximal end 45a of the handle portion; and (ii) the distal weighted end 50 at a distal end 45b of the handle portion.

[0101] At the distal weighted end 25 there is located a proximal bar portion 26, a connector 28 and a distal weight assembly 50. The proximal bar portion 26 is contiguous and axially aligned with the handle portion 45. The connector 28 is fixedly secured to the distal end 26a of the proximal bar portion 26. In one embodiment it is fixedly secured to the distal weight assembly 50; and in another embodiment it is releasably secured to the distal weight assembly 50.

[0102] The connector 28 has an axial sleeve 28a to secure the distal end 26a of the proximal bar portion 26 and an axial outer socket 35 to interconnect with the distal weight assembly 50. The distal end 26a of the proximal bar portion 26 has an axial spigot 32a to fit within the axial sleeve 28a forming a spigot-in-socket connection between the two.

[0103] The distal weight assembly 50 comprises an end closure 44 and one or more weights in the form of weight discs 42. The axial outer socket 35 interconnects with the weight assembly 50 to fixedly locate the weight or weights with the proximal bar portion 26.

[0104] Different embodiments of the weight assembly 50 and connector 28 will be described later according to the different types of batons.

[0105] At the proximal support end 30, the arm supporting portion 40 has a proximal end closure 41 for fitting over an opposing axial spigot 32b and a securing portion 43 disposed for attachment to the arm band connector 100 by means of a webbing strap 110. The webbing strap 110 works as part of the arm band connector 100 in conjunction with the arm supporting portion 40 to fixedly bind the baton to an arm 4 of a user 3 of the exercise device 10 as shown in Figures 2 and 11. The handle portion 45 is especially disposed for gripping by the hand, fingers 5 and thumb 6 of the user 3.

[0106] The arm supporting portion 40 is of sufficient longitudinal extent and is enlarged relative to the handle portion 45 to provide support to the arm 4 and adjacent wrist 7 of the user 3. The handle portion 45 is contiguous with the arm supporting portion 40 and has a tapered intermediate portion 47, or in an alternative embodiment a stepped portion, to gradually reduce the peripheral surface of the baton from the arm supporting portion 40 to the handle portion 45. This allows the arm, wrist and hand to follow the contour of the arm supporting portion 40 and the handle portion 45 in locking engagement therewith to resist angular movement between the arm and wrist of the user, which further supports the wrist 7 of the user 3 in position, mitigating the stress imposed on the wrist by holding the baton 20.

[0107] In this arrangement, the hand of a user 3 of the exercise device 10 may comfortably grip the baton 20 with the wrist 7 maintained in a locked position relative to the arm 4 to reduce stress on the wrist whilst moving the baton.

[0108] The securing portion 43 comprises a recess 48 within the arm supporting portion 40 incorporating a glide buckle 49. The buckle 49 is of a tri-glide buckle type having a pair of slots 49A and a bar 49B through which the webbing 120 of the webbing strap 110 is fed.

[0109] The arm band connector 100 comprises the webbing strap 110 and a forearm and wrist brace 130 moulded to conform to the general shape of a user's outer forearm adjoining the wrist. The webbing 120 that forms part of the webbing strap 110 has a fastener 140 provided at its terminal ends to positively engage and bind the brace 130 to the outer forearm 4 and wrist of the user 3.

[0110] The fastener 140 in the present embodiment is of the snap lock time and includes hook and loop fasteners of the Velcro TM type for tightening and adjustment.

[0111] Moreover, the webbing 120 is adapted to feed through the buckle 49 and the terminal ends of the strap are fastened to positively secure and bind the support end of the baton to the inner forearm wrist of the user by tightening the fastener against the brace 130 on the outer forearm 4 and wrist 7 of a user 3, clamping the forearm and wrist in a holding position for the fingers 5 and thumb 6 of the user to grasp the handle portion 45 of the baton 20.

[0112] Thus, the securing portion 43 is disposed proximate to the intermediate portion 47 at an optimal distance therefrom to locate the pivot point of the wrist of the user at a position so that the arm, wrist and hand follow the contour of the intermediate portion. This allows the webbing to bind the same together when the fingers grip the handle portion to prevent angular movement therebetween during rapid reciprocating hand movement of the user.

[0113] In the present embodiment, as shown in Figures 3 and 6 to 11, the distal weight assembly 50 is detachable and comprises a capsule 48 containing the weight or weights therein in the form of weight-discs 42. The capsule 48 is formed in two halves 48a and 48b and is closed at a distal end 48c and open at a proximal end 48d to fit different combinations of weight-discs 42 therein.

[0114] The capsule 48 has fitted thereto at its open end 48d a plug end 34 having a hollow stem 52 projecting outwardly to be received within the axial outer socket of the connector 38 and a circumferential flange 55 for fitting over the proximal end 48d of the capsule 48. The circumferential flange 55 has a plurality of transverse apertures 55a and the outer surface has a corresponding series of clips 56, so that plug end 34 may be positively clipped into position to close the two halves of the capsule together.

[0115] The end closure 44 is then overmolded, bonding to the capsule 48 and the circumferential flange 55 of the plug end 34, encapsulating the capsule 48 and weight or weights therein.

[0116] The capsule 48 is formed with a plurality of slots 46 for accommodating one or more-disc weights 42 therein as shown in Figures 8E to 8H.

[0117] The hollow stem 52 of the plug end 34 is of complementary shape to the axial outer socket 35 of the connector to fit and be positively and lockingly engaged therein.

[0118] In this arrangement, the plug end 34 has an inner radial flange 52a and is formed to define an aperture 52b that in combination constitute one component of a bayonet fitting and the axial outer socket 35 is formed to define the other component of the bayonet fitting.

[0119] The axial outer socket 35 is formed with an inner boss 56, a protruding stem 54 of complementary cross sectional shape to the aperture 52b, a sliding plate 59 and a biasing spring 60 to outwardly bias the sliding plate 59 axially along the stem 54 so that when the two components of the bayonet fitting are brought into mating axially forced engagement with each other one can be rotated relative to the other and axially locked together. In this manner, the weight assembly 50 is interconnected to the proximal bar portion 26 to form an integral baton with a weighted end.

[0120] In other embodiments, the plug end and axial outer socket can be of a variety of different types of engagement means selected from a group of detachable couplings consisting of snap-lock, male/female locking, spring-loaded locking, thread and screw and push-press mechanisms to achieve the desired detachable and locking engagement.

[0121] In one embodiment the weight assembly 50 can be made of the same material as the baton 20 or in an alternative embodiment as a metal weight or even a combination of metal and elastomeric / plastic combination.

[0122] In the present embodiment, the detachable weight 50 is selected as one from a group of weights of corresponding design but of differing numbers to provide for differently weighted weight assemblies that can be individually substituted for each other to fit to the same proximal bar portion. These differing weights are in the range from around 25 to 500 grams per weight. In one embodiment, the lower range is from 25 to 100 grams, which are suitable for use by children. In other embodiments, the weights are provided as 100 gram or 300 gram weights, which are more appropriate for use by adult users and can be combined in combinations of 1 to 4 to provide different net weights.

[0123] In the present embodiment the weight assemblies 50 are provided as colour coded weights for ease of identification and use.

[0124] In alternative embodiments of the best mode, the second and third types of baton with a fixed weight assembly 50', 50" for housing higher weights and moderate weights, are described with reference to Figures 12 to 17 and Figures 18 to 21 respectively.

[0125] In these alternative embodiments, the end closure 44', 44" of the weight assembly 50', 50' is overmolded to fixedly interconnect directly with the axial outer socket 35', 35" of the connector 28', 28" to define a recess therein to fixedly retain the weight or weights within the recess. These weights are again in the form of weight-discs 42', 42", but instead of being disposed in a capsule, are accommodated within the axial outer socket 35', 35" of the connector 28', 28", directly.

[0126] In these embodiments, different variations of the weight assembly 50', 50" are provided with different combinations of weights. The end closure 44', 44" is formed with an axial spigot portion 44a, 44b or 44c of commensurate axial extent to impress against the outer face 42a of the outer weight, infilling any void otherwise created by omitting one or more weights within the recess.

[0127] To accommodate higher weights and moderate weights the two types of batons 20', 20" with fixed weight assemblies 50', 50" differ in that the embodiment of the second type of baton 20' for housing higher weights of, for example, 300 grams each, has a connector 28' that is flared to accommodate larger diameter weight discs. Thus, the axial outer socket 35' is of a larger diameter than the diameter of the proximal bar portion 26', whereby the inner end of the axial outer socket 35' defines an inner step 35a to engage and support the peripheral edge of the inner face 42b' of the inner weight disc in fixed position.

[0128] In the case of the embodiment of the third type of baton 20" for housing moderate weights of, for example, 100 grams each, the connector 28" is not flared and thus the axial outer socket 35" is of commensurate diameter to the external diameter of the proximal bar portion 26". Consequently, there is of lesser radial extent to provide a smaller inner step 35a".

[0129] This is best illustrated in Figures 20B to 20D, whereby in this embodiment, the connector 28" is formed with a central protrusion 57 within the axial outer socket defining a supporting face 57a juxtaposed to the inner face 42b of the inner weight to fixedly support the weight or weights within the recess, in conjunction with the smaller inner step 35".

[0130] In each of the preceding embodiments, the baton is formed of an inner cellular core 16 comprising a pair of inner longitudinal core halves 16a and 16b. These core halves 16 form the core of the proximal support end 30 and the proximal bar portion 26 of the distal weighted end 25 as an integral member.

[0131] The cellular core 16 comprises a lattice of cavities 22 of varying volume in a honeycomb type structure to reduce the weight of the baton whilst maintaining its strength and to define a scaffolding 48 to rigidify the proximal support end 30.

[0132] The scaffolding 48 is formed by a series of cavities 22 within the inner cellular core 16 having a lower density disposed within the proximal support end 30 of the core relative to the proximal bar portion 26 of the core. Moreover, the scaffolding 48 is defined by an inner longitudinal extending portion of solid material and an annular portion of smaller volume cavities within the proximal support end relative to the proximal bar portion 26 having larger volume cavities 22 disposed within it.

[0133] As shown in Figure 15, the core halves 16 are of complementary shape, the upper half 16a being provided with a series of transversely projecting locating pins 18a along the central axis thereof and the lower half 16b being provided with a series of corresponding axial grooves 18b to receive the same when brought together in interlocking engagement.

[0134] Further, the upper core half 16a is formed with a peripheral tongue 52b and the lower core half 16b is formed with a peripheral groove, to similarly mate when brought together in interlocking engagement.

[0135] As best shown in Figures 12 to 14 of the second type of baton, the core halves 16a and 16b are brought into interlocking engagement using the locating pins 18a and axial grooves 18b aligning the cell structure to form the transverse cavities as shown in Figure 14.

[0136] The structure is then fixed by fitting the axial sleeve 28a of the connector 28 and the proximal end closure 41 over the axial spigot 32a and opposing axial spigot of the core halves 16 respectively.

[0137] An overlay encasement is then compression molded, binding the inner cellular core halves 16 and the proximal end closure 41 and connector 28 together to form an integrated proximal support end 30 and proximal bar portion 26 to connect to the distal weight assembly 50.

[0138] By virtue of this construction incorporating the scaffolding, the distal weighted end 25 is flexible relative to the arm supporting portion 40 and the handle portion 45 to establish a resistant force to the arms when torque is applied from rapid reciprocating hand movement. Consequently, the flexing of the distal weighted end occurs about a pivot point 58 disposed proximate to the distal end b of the handle portion 45.

[0139] The baton 20 is made of a resiliently flexible polymeric material, and is compression molded. Compression molding creates a chemical bond between the polymeric material and the metal components of the baton. It also allows for the creation of uneven wall surfaces, which may not be able to be attained using injection molding techniques.

[0140] One such polymeric material is an ethylene propylene diene monomer rubber such as EPDM with a Shore rating of 65 +/- 5. Alternative materials include blended thermoplastic polymers including combinations such as nylon

+ polyurethane +/- Seblex (7848 which is a low flow, oil extended thermoplastic styrene rubber modified polypropylene).

[0141] As already noted the additional weights can also be made from these same materials or suitable metals or a composite metal/ elastomeric arrangement.

The baton 20 is provided in a variety of lengths and weights which are designed for use by different users. As examples a standard length for use by men and women would be, but not limited to, 480 mm and for children 300 mm. The lengths are not limited to the previously mentioned lengths and can extend from about 300 mm to about 900 mm. The latter length being particularly suitable for use by professional athletes or for use in specific exercise regimes such as martial arts (samurai exercises). Equally, the baton 20 is provided in a range of diameters again adapted for various exercise routines and users. Example diameter ranges are from 25 mm to 60 mm.

[0142] The second mode of the invention is described with reference to a specific embodiment shown in Figures 22 to 27B. The second mode is substantially similar to the first mode except an alternative arrangement of the arm supporting portion, securing portion and arm band connector are provided allowing for attachment of the arm band connector to a user and then selective connection and release to the weighted baton. Also an alternative form of weight is provided.

[0143] Notwithstanding these differences, the exercise device can be used in an identical manner to the exercising device of the first mode, as shown in Figure 22.

[0144] As shown in Figures 23 and 24 the baton of the exercise device 10' of the present embodiment is shown in exploded form to illustrate the construction and securement of the arm supporting portion 40' and attachment of the weight 50'to a rod portion 20' of the baton in detail.

[0145] In the present embodiment, the weight 50' similarly comprises a body section 50A' and engagement attachment 50B' that is designed to releasably engage with a receiving portion 35' of the rod 20'. The engagement attachment B' is formed with an extension pin 51A', to be located centrally within a corresponding socket 51B' formed in the receiving portion 35' at the distal end 25' of the rod 20', as indicated in the direction shown by the arrow.

[0146] The receiving portion 35' and extension pin 51A' can be provided as any one of a selection of securable co-operating means such as a screw and thread arrangement, where the engagement attachment 50B' is threaded and engages with a complementary threaded receiving portion 35', a spring-loaded lock system, push-press engagement mechanism or as a male and female connecting arrangement.

[0147] In a particular embodiment, the receiving portion 35' is located within a pre formed cavity in the distal end of the rod 20' that is made during the manufacturing process such as a moulding process, and the receiving portion is secured therein. The engagement attachment 50B' is similarly located and affixed to a pre-formed cavity that is made during the moulding or assembly of the weight 50'.

[0148] As shown more clearly in Figure 24, the arm supporting portion 40' comprises two semi-circular halves 65 and 65A that when assembled are fixedly secured to the proximal end of the rod 20'. In this embodiment, the semi-circular halves 65 and 65A form an extension to the rod 20' to form the arm supporting portion 40'.

[0149] The arm supporting portion 40' attaches to the rod 20' via a fixing arrangement 70 having semi-circular (arcuate) ridges or the like located on the inner surfaces of the semi-circular halves 65 and 65A that engage with corresponding grooves 75 located on the outer surfaces of the rod 20'fifth.

[0150] The securing portion 43' of the present embodiment comprises a recess 48' within the arm supporting portion 40'defining a longitudinal slot 90 extending axially along a portion of the arm supporting portion periphery and an expanded opening A at one end of the slot. This permits access of a terminal head 81 and shank 81A of a connector pin 80 into and out of the longitudinal slot 90, the connector pin forming part of the arm band connector 100', which will be described in more detail later.

[0151] The longitudinal slot 90 is closed towards the proximal support end 30' and open towards the distal weighted end 25' forming a continuous passage into the expanded opening 90A. The expanded opening 90A is shaped substantially in the form of a circle or oval to permit ingress and egress of the terminal head 81.

[0152] The longitudinal slot 90 is disposed within a housing assembly 85 formed with a slotted opening 85A surmounting the longitudinal slot to define a cavity within the recess 43'. In this arrangement, the housing assembly 85 is disposed externally of the locus of the periphery surface.

[0153] The slotted opening 85A is aligned with the longitudinal slot 90 and opens into the expanded opening 90A to define the passage and receive the shank 81A of the connector pin 80 with the terminal head 81 disposed within the cavity to allow movement within and along the longitudinal slot.

[0154] The recess 43' receives terminal head of the connector pin 80 that is held in place by the housing assembly 85 that extends substantially along the length of a longitudinal slot 90 formed within the upper body 65A or directly in the surface of the rod 20'. The housing assembly 85 surmounts the upper surface of the rod 20' over the slot 90, and is secured to the upper housing 65A or the rod 20'.

[0155] The housing assembly 85 includes the slotted opening 85A on its upper surface and has at its proximal end a buffer stop where the slotted opening 85A extends from the buffer stop substantially the length of the housing assembly to an end opening located at the distal end of the housing assembly. The end opening lies adjacent an expanded opening 90A which is itself formed at the distal end of the longitudinal slot 90 and preferably within the body of the rod 20', which allows the connector pin 80 to be removed from the securing portion 43'. This arrangement allows the terminal head of the connector pin 80 to slide along the longitudinal slot whilst being guided by the slotted opening 85A and moved along the longitudinal slot 90 so it can be removed with minimal effort from expanded opening 90A, as an egress point.

[0156] The connector pin 80 slides along and is held in place by the slotted opening A.

[0157] In an alternative embodiment the longitudinal slot 90 through which connector pin 80 travels can be formed integrally with the rod 20' during manufacture.

[0158] The rod 20' is provided as a resiliently flexible rod and is capable of moving in a partially undulating form (wave like) and within a limited range of movement. The range of movement / flexibility is within a range of 1 degree to 45 degrees as measured from the vertical axis of the rod 20 and from at or near the distal end of the baton.

[0159] As shown in Figure 25 the arm band connector 100'comprises a detachable wrist and arm support band 100A and a carriage assembly 100B tethered thereto for connecting to the securing portion 43' of the baton.

[0160] Moreover, the wrist and arm support band 100A comprises a band of material form a wrist strap 120' that securely wraps around the wrist 7 of the user 3. The band of material is resiliently expandable and is secured by a fastener (not shown) selected from the group consisting of elasticised straps, straps having a releasable belt and bucket assembly, straps having hook and eye securing means (Velcro), and straps having snap / lock fastening means.

[0161] The carriage assembly 100B comprises a connector plate 105 and the connector pin 80. The shank 81A of the connector pin 80 projects outwardly from a connector side of the connector plate 105 and has a diameter marginally less than the transverse extent of the slotted opening 85A. The terminal head 81 of the connector pin 80 is disposed at the distal end of the shank 81A and has a transverse extent greater than the transverse extent of the longitudinal slot 90 and marginally less than the transverse extent of the recess 43' disposed on the underside of the slotted opening 85A.

[0162] The expanded opening is shaped substantially in the form of a circle or oval of marginally greater transverse extent than the terminal head 81 to permit the ingress and egress of the terminal head into the opening and the longitudinal slot 90.

[0163] The terminal head 81 can be retainably engaged within the longitudinal slot by entering the expanded opening 90A and slide along the slot with the shank 81A reposed within the slotted opening 85A. In this manner the underside of the head 81 is positively retained by the underside of the slotted opening 85A and the shank 81A is capable of moving marginally along and rotatably within the slotted opening.

[0164]The carriage assembly 110B further comprises a tether 110' fixedly connected at one end thereto and at the other end to the wrist and arm band support 100A thereby tethering the carriage assembly to the wrist and arm band support.

[0165] In one embodiment the connector plate 105 connects to the shank 81A by a releasable mechanism. This can be via a simple snap/lock mechanism or alternatively a nut and bolt. A simple releasable screw mechanism where the shank 81A has on its upper portion a threaded section over which the wrist strap 120' can be placed and secured in place with a nut 82. In one embodiment the entire bolt assembly is conveniently able to be removed for replacement purposes and cleaning. In a further preferred embodiment, the tether 110 can be fixedly attached to the shank by means such as a press rivet.

[0166] In a further embodiment, the connector plate 110' includes a slot (not shown) through which the arm band connector 100'can be connected via a looped webbing arrangement. The webbing is fixedly attached, such as by stitching, to the wrist strap 120' or by being looped through a slot and stitched back onto itself. The webbing can be made of a variety of materials such as neoprene or other suitable resiliently elastomeric material. The connector plate 110' can be made from similar webbing material or in some instances a light-weight metal alloy, a mild steel, or aluminium.

[0167] The wrist strap 120' securely encircles the wrist of a user 3 in order to avoid excess movement of the wrist strap. The wrist strap 120' is expandable so it can be used by a variety of users.

[0168] Turning to Figure 26 there is shown a cut away side view of baton. In this embodiment the slot 90 is integral with the body of the rod 20' and again can be formed during the moulding process. The upper edges of the slot 90 are contiguous with the outer surface of the rod 20'.

[0169] In this embodiment the connector pin 80 is held in place by the housing assembly 85 that is located substantially over and parallel with the top of the cavity , but also allows removal of the connector pin through the expanded opening 90A and through the end opening of the slotted opening 85A.

[0170] The housing assembly 85 is permanently affixed to the rod 20', but can be provided as a releasable version being secured to the rod by a screw / rivet 86.

[0171] The terminal head 81 of the connector pin 80 can be rounded, hexagonal, square, a square head with bevelled edges, or other shapes, where the head shape allows the bolt to be able to rotate within the longitudinal slot 90.

[0172] Similarly, the screw head has a flattened surface thereby allowing the connector pin 80 to easily slide / travel along the longitudinal slot 90 and be removed at the expanded opening 90A.

[0173] The connector plate 110' can be secured to the shank 81A by a releasable screw arrangement or by a press rivet. At the other end of the tether 110' it can be attached to the wrist strap 120' by direct stitching or a releasable buckle assembly or other means known to those in the art.

[0174] Turning to Figures 27A and 27B there are shown cut away sections of the baton 10' and in particular the arm supporting portion 40'. The connector pin 80 is inserted into the longitudinal slot 90 via the expanded opening 90A in the direction shown by the arrow in Figure 17A and can also be removed via the open section of the expanded opening 90A. The connector pin 90 is adapted to travel along the longitudinal slot 90, being held in place by the housing assembly 85. The extent of the travel is limited by the buffer stop provided by the closed proximal end of the longitudinal slot 90.

[0175] When the baton is not in use the user can simply release / drop the baton and the entire assembly 10 can hang freely.

[0176] In one embodiment, the handle portion adjacent to the arm supporting portion 40' is provided with a hand gripping section (not shown) thereby allowing the user to grip the baton. This gripping section can be in the form of a rubber or plasticised grip zone, having a raised or indented surface for improved grip or a moulded hand section in which the hand of a user can easily fit or engage with and thus allow the user's fingers 5 to partially encase a portion of the rod 20'.

[0177] The third embodiment of the invention is substantially similar to the proceeding embodiment, except that the longitudinal slot and the expanded opening are disposed within a housing assembly formed with a slotted opening surmounting the longitudinal slot and the expanded opening to define a cavity within the recess, so that the housing assembly is contained within the locus of the periphery surface of the arm supporting portion.

[0178] Furthermore, the recess of the securing portion within the arm supporting portion incorporates a releasable locking assembly to lock the terminal ahead within the slotted opening.

[0179] While various embodiments have been described with reference to specific example embodiments, it will be evident that various modifications and changes may be made to these embodiments without departing from the broader scope of the technology.
