DESCRIPTION OF EMBODIMENTS

It should be noted in the following description that like or the same reference numerals in different embodiments denote the same or similar features.
FIGS. 1 to 7 show an exercise device 10 according to a preferred embodiment of the present invention. The exercise device 10 comprises a hollow body 12 having a handle 20 and a valve assembly 30.
The body 12 comprises a tubular mid-portion 14 with substantially hemispherical first and second end portions 15 and 16 which together define an internal cavity 18 within the body 12. The body 12 is made from a flexible fluid impervious wall material. The cavity 18 can be substantially emptied to configure the body 12 into a collapsed substantially flat configuration (substantially shown in FIG. 3), and the cavity 18 can be substantially filled to configure the body 12 into a (filled) expanded configuration (as shown in FIGS. 1, 2 and 7). The body 12 is at most about 30 cm in length and 20 cm in width/diameter when in the expanded configuration. In the preferred embodiment, the body 12 is 26 cm in length and 16 cm in width in the expanded configuration.
The body 12 is made from polyurethane, polyvinyl chloride (PVC) or chlorosulfonated polyethylene (CSPE) synthetic rubber (CSM) such as that sold under the trade marks HYPALON, TOSOH-CSM and EXTOS.
The valve assembly 30 comprises an internally threaded tube 17 and a valve housing 35. The tube 17 is mounted to an aperture 19 formed in the first end portion 15. The valve housing 35 comprises an externally threaded hollow first section 31 and a generally flat second section 32. The second section 32 includes a central recess 33 within which a one way filling valve 36 is mounted. The central recess 33 also includes an internal thread or bayonet mount tabs which are engaged by a closing cap 38 for covering the valve cavity 33 and the protecting the filling valve 36.
When the valve housing 35 is attached to the tube 17 as shown in FIGS. 1 and 2, the second section 32 is substantially flush with the external surface of the first end portion 15. The filling valve 36 functions as a one way valve which means air can be pumped into the cavity 18 but does not allow air to escape from the cavity 18 except when desired. A valve adaptor (not shown) is used which attaches to the threads or mount tabs of the central recess 33. The valve adaptor is attached to a hose nozzle of an air pump (not shown), which can be a manual or an electric air pump. Thus, the cavity 18 can be filled with air into the expanded configuration of the body 12.
Additionally or alternatively, the cavity 18 can be partially or fully filled with liquid such as water. In this case, a liquid valve adaptor can be used which attaches to the cavity 33. Such an adaptor allows liquid to be inserted into the cavity 18 as desired via the valve 36 without having to remove the valve housing 35. Alternatively, the valve housing 35 can be removed from the tube 17 by unthreading using a valve wrench 40. Water can then be poured into the cavity 18 as desired, until it is full or only partially full. The remaining space in the cavity 18 is then filled with air by reattaching the valve housing 35 to the body 12. Further alternatively, the cavity 18 can be partially or fully filled with a solid product such as sand if a heavy weight is desired.
The handle 20 is fixedly attached to a side wall of the mid-portion 14. The handle 20 comprises a grip 21 and first and second mounting means 25 a and 25 b attached to ends thereof. The grip 21 comprises a curved rubberised tube dimensioned for gripping with a user's hand and fingers and adapted to avoid slippage. The grip 21 comprises end straps 22 a and 22 b which attach to the respective mounting means 25 a and 25 b.
As shown in FIGS. 4 to 6, each mounting means 25 comprises a first pad 26 and a second larger pad 27. The first pad 26 is attached to a lower surface of a respective end strap 22, and a lower surface of the first pad 26 is attached to the mid-portion 14. The second (larger) pad 27 is the positioned over a respective end strap 22 and first pad 26, and attached thereto. Edges of the second pad 27 extending beyond the edges of the first pad 26 are attached to the mid-portion 14. The first and second pads 26 and 27 are attached to the mid-portion 14 and to each other via suitable means, such as cold glue or other suitable adhesive. This ensures that the mounting means 25 are fixedly attached to the body 12 to securely attach the grip 21 thereto.
Use of the exercise device 10 will now be described. In the empty unassembled configuration, the exercise device 10 is soft, light, small in size and easily transported. To use, the exercise device 10 is filled as desired with only air, only water, sand or any mixture thereof, using the filling attachment nozzles which can be done in about one minute.
The exercise device 10 can then be used in conjunction with any exercise, such as lifting, walking, jogging, lunges, jumping, skipping, running, or it can be used in exercises similar to those used with medicine balls and kettle bells. The exercise device 10 can also be used in conjunction with many other exercise items like Swiss Balls. Because of the soft wall structure of the exercise device 10, it can be swung around with possible injury from impacts with the body being reduced compared to steel weights and kettlebells.
The assembled exercise device 10 is user friendly as it is soft and comfortable to use, and minimises potential injury and safety issues. In a partially liquid filled state (10% to 80% water filled and the rest air filled), the water will slosh within the cavity 18 and this unstableness requires the user to stabilise the exercise device 10 using his core and stabilising muscles, thus providing an advantage not provided by other exercise devices. The exercise device 10 allows a user to emulate sport functional exercises such as cricket bowling, tennis swing or golf swing. The exercise device 10 can also be used in the water for aqua exercises for rehabilitation or elderly exercises. When used in a stable format (full of water or solid material such as sand), the exercise device 10 is then used as a true weighted training device.
The exercise device 10 thus provides a number of advantages. Typically, only specialised water equipment can be used for training in the water. However, the exercise device 10 can also be used for exercising in the water. The exercise device 10 is user friendly and can be used in a huge number of different exercises. The exercise device 10 is light and packs flat when empty which makes it handy to take and use on holidays, which is generally not possible with conventional weights. The exercise device 10 can be made into any shape, colour and can include a pattern or advertising thereon. It can be used in aqua training aid for the elderly and injury rehabilitation. The exercise device 10 can be used in a stable or unstable form, which provides a distinct advantage over conventional weights. It can also be used for sports specific exercises and movements. The exercise device 10 is very strong & durable and can be thrown to the ground. This is handy for example in Boot Camp style group classes where participants can perform lifting exercises with the exercise device 10 and drop it to the ground before doing a sprint. The risk of injury to the participant and damage to the ground is minimised compared to conventional weights. Resistance, Kettlebell, compound, isolation, functional, cardiovascular and power training exercises are thus all possible with the exercise device 10.
The exercise device folds substantially flat and is very light when empty. This allows a personal trainer for example to easily transport ten or more of such exercise device 10 in a bag in the collapsed state, and then assemble the exercise device 10 prior to a group class for use by participants using an air pump and a water tap on site. The exercise device 10 can then be collapsed again after a group class. In contrast, such number of conventional steel weights generally cannot be conveniently carried. Another advantage of the present exercise device is that the weight thereof can be varied as desired.
It is apparent that modifications can be made with the exercise device 10 described. For example, the cavity 18 can be formed with multiple chambers which may be separately inflated or filled with different materials. For example, one half of the exercise device 10 can be filled with water and the other half filled with air. This provides different exercise dynamics to the exercise device 10. In other possibilities, the chambers can extend the length of the exercise device 10. Also, the chambers for liquids can be formed in a helical manner within the cavity 18, which can add to the unstableness of the direction of liquid sloshing within the cavity 18.
In relation to the handle, the handle can be made to have a rigid attachment to the exercise device body, rather than the flexible end strap attachment shown in the exercise device 10. Also, the grip can be configured into a glove shaped attachment such that the user grips the body 12. The exercise device body can also be provided with more than one handle, for example two handles on opposing sides. The handles can alternatively be provided at one end portion or both end portions.
A ring or other connection means can also be attached to one or both end portions. The ring can be used to attach two or more exercise devices to each other via a connecting strap. Also, when filled with water or solid material such as sand, a user can wear a harness which is attached to the exercise device such that the user would then drag the exercise device whilst doing walking, jogging, sprints, etc.
The cover cap 38 can also include a soft cover to avoid any injury to users.
FIGS. 8 to 10 show an exercise device 10 a according to a second preferred embodiment of the present invention. The exercise device 10 a is similar to the exercise device 10 above and also comprises a hollow body 12 a and a valve assembly 30 a. The body 12 a also comprises a tubular mid-portion 14 a with substantially hemispherical first and second end portions 15 a and 16 a. The body 12 a in this embodiment is still about 16 cm in width/diameter when in the expanded configuration.
The main differences between the exercise device 10 a and the exercise device 10 above are that the exercise device 10 a is longer at about 75 cm in length, includes a solid weight within its cavity 18 and includes four handles 20 as further described below.
The cavity 18 comprises at least one supplementary weight (not shown) therein, such as a four or five kilo lead or steel weight fixedly attached to an internal wall of the cavity 18. The supplementary weight(s) can be positioned anywhere along the longitudinal length of the body 12 a but is preferably positioned at a centre portion thereof. It is however possible to have the supplementary weight(s) disposed off centre to the longitudinal length of the body 12 a to provide different exercise dynamics. It is also possible to have two or more of such weights either side by side or spaced along the longitudinal length of the body 12 a.
The supplementary weight(s) can also be of any desired shape and can be positioned anywhere along the inner circumference of the cavity 18. In the preferred embodiment, the supplementary weight has a round circumference which fits with the inner circumference of the cavity 18. It is however possible to have the supplementary weight(s) disposed off centre to the central longitudinal axis 24 a of the body 12 a to provide different exercise dynamics. The supplementary weight(s) can also be longitudinally extended in shape and two or more of such weights can be spaced relative to the central longitudinal axis 24 a of the body 12 a.
The remainder of the cavity 18 not occupied by the supplementary weight(s) can be fully filled or partially filled with other material, such as sand, air, water, or any combination thereof. The cavity 18 can be divided into chambers which individually receives the materials as desired.
The exercise device 10 comprises four handles, a first pair 23 a being handles 20 a and 20 b, and a second pair being handles 20 c and 20 d. The handles 20 a and 20 b of the first pair 23 a are arranged adjacent the respective first and second end portions 15 a and 16 a, with their grips 21 a and 21 b generally parallel to each other and transverse to the central longitudinal axis 24 a of the body 12 a. The first pair 23 a of handles thus allows a user to have a wide grip on the exercise device 10 a. The handles 20 c and 20 d of the second pair 23 b are arranged inwardly of the first pair 23 a with their grips 21 c and 21 d generally aligned with each other and parallel to the central longitudinal axis 24 a of the body 12 a. The second pair 23 b of handles thus allows a user to have a narrower straight grip on the exercise device 10 a.
The exercise device 10 a thus provides a vast array of exercises with a heavier weight as well as two handed dynamic exercises.
FIG. 11 shows the exercise device of FIGS. 1 to 7 with a modified handle 20 e. The handle 20 e is fixedly attached to a side wall of the mid-portion 14. In this embodiment, the effective length of the grip 21 between the first and second mounting means 25 a and 25 b is adjustable. The handle 20 e comprises the first and second mounting means 25 a and 25 b and the grip 21 comprises an elongated strap 21. The second mounting means 25 b includes a ring 29 attached thereto. The strap 21 has a first end portion 28 a attached to the mounting means 25 a, the strap 21 is then looped through the ring 29 and a second end portion of the strap 28 b is adjustably attached back to the first end portion 28 a via hook and loop means (VELCRO™), buttons or other suitable attachment which allows the effective length of the strap 21 between the first and second mounting means 25 a and 25 b to be adjustable.
FIG. 12 shows the exercise device of FIGS. 8 to 10 with two modified handles 20 e. The handles 20 e are the same position as the handles 21 c and 21 d described above.
The adjustable handle 20 e allows a user to use such handles 20 e as foot straps, in that the user can insert their respective foot between the mid-portion 14 and the handles 20 e, tighten the grip 21 onto their foot, and perform exercises as desired.
FIG. 13 shows another embodiment of the modified handle 20 f which allows for the effective length of the grip 21 between the first and second mounting means 25 a and 25 b to be adjustable. The grip 21 in this embodiment comprises a first portion 21 a attached to the first mounting means 25 a and a second portion 21 b attached to the second mounting means 25 b. The first portion 21 a has a lower section 61 and an upper section 62. In use, the second portion 21 b is sandwiched between the lower and upper sections 61 and 62 and attached to each other via hook and loop means (VELCRO™). By adjusting the position of the second portion 21 b relative to the first portion 21 a, the effective length of the strap 21 between the first and second mounting means 25 a and 25 b is adjustable
In other embodiments, the first and second portions 21 a and 21 b can be connectable to each other via suitable buckles such as side release buckles used in bags and camping equipment. The respective length of the first and second portions 21 a and 21 b will then be made adjustable prior to these portions being connected to each other via the buckle, which thus allows the effective length of the strap 21 to be adjustable.
In other possible modifications, the body can be of any desired dimensions and can have a diameter of 25 cm to 32 cm and a length 1 m to 1.2 m. The number of handles 20 may vary from 2 to 8, or adjustable handles 20 e or 20 f which can vary in number from 2 to 6. Such devices allow for many different exercises.
FIGS. 14 and 15 show an exercise device 10 b in accordance with another embodiment of the present invention. The exercise device 10 b is similar to the exercise device 10 a above and also comprises a hollow body 12 b and a valve assembly 30. The body 12 a also comprises a tubular mid-portion 14 a with substantially hemispherical first and second end portions 15 a and 16 a.
The body 12 b in this embodiment has a maximum width/diameter of 30 cm when in the expanded configuration and a maximum length of 120 cm. The cavity 18 can also comprises at least one supplementary weight (not shown) therein if desired,
The exercise device 10 b comprises six handles, being handles 20 a to 20 c on one side and handles 20 d to 20 f on an opposite side thereof. The handles 20 on each respective side are disposed with their grips 21 generally aligned with each other and parallel to the central longitudinal axis 24 a of the body 12 b.
The handles 20 a and 20 d, 20 c and 20 f are arranged adjacent the respective first and second end portions 15 a and 16 a. The handles 20 b and 20 e are arranged at the mid-portion 14 a.
The handles 20 can have a fixed length or be variable length handles and the device 10 b can have any desired combination of such handles. The exercise device 10 b, due to its size and handle configuration again provides different exercises to the other exercise devices above.
FIGS. 16 to 18 show the exercise device 10 b with device floor retainers 80 for use of the exercise device 10 b as an exercise bench.
Referring to FIGS. 19 and 20, each device floor retainer 80 comprises two wedge portions 82 joined at their narrow edge portions 84. Each floor retainer 80 thus forms a generally concave upper portion 86 and a flat lower portion 88.
Referring back to FIGS. 16 to 18, the floor retainers 80 are positioned in a spaced manner with the lower portions 88 engaging the floor or table 100. The exercise device 10 b is then disposed over the concave upper portions 86 such that the exercise device 10 b is retained laterally by the wedge portions 82.
The exercise device 10 b can then be used as a resistance training bench and core balance device. A user can lay on the body 12 between the handles 20. Also, by using the different handles 20, the exercise device 10 b can be used as an unstable resistance training device.
FIG. 20 shows the collapsed exercise device of FIG. 14 and folded device floor retainers of FIG. 19. This allows the device to be transported or stored easily unlike conventional exercise benches.
In another embodiment, the retainers 80 can be formed with elevated platforms for raising the exercise device 10 b off the ground. The elevated platforms can also have differing heights for orienting the exercise device 10 b at an inclined angle.
Further, with air out of the exercise device 10 b and having water or sand within its cavity 18, the exercise device 10 b can be used like a Sand Bag. FIG. 21 is an end perspective view of the exercise device 10 b showing an attachment and/or ring 90 for attaching the exercise device 10 b to an exercise harness.
In another possible embodiment of the exercise device 10, the handle can only have one mounting means with the other end being a free end.
The present invention also provides a set of exercise devices comprising at least one of each of the exercise devices 10 and 10 a, and preferably with the exercise device 10 b, and preferably with the floor retainers 80.
