DETAILED DESCRIPTION

(5) Referring to FIG. 1, there are shown two parallel, rigid, members 1 and 2 (which may or may not be mounted to a rigid free-standing structure, or to a ceiling), upon which run trolleys 3 and 4, respectively. In this embodiment the members 1 and 2 are made of metal, but it is understood that other materials may be used. The members may be tubular to engage with a pulley wheel, however other profiles are envisaged which match a pulley wheel profile.

(6) The trolleys 3 and 4 are free to move linearly along, and rotate about the axes of, the members 1 and 2. The members 1 and 2 may or may not be sleeved in another material for any purpose, including that of reducing resistance to either or both of the linear and rotational motions of the trolleys 3 and 4, or for the purpose of reducing noise as the trolleys 3 and 4 move.

(7) The trolleys 3 and 4 attach to either end of a further rigid, tubular member 5 of substantially similar characteristics to members 1 and 2 through motive mechanisms, such as hooks 8 and 9 not illustrated in detail, but which have the capacity for rotational motion with respect to the trolleys 3 and 4. The attachment of the member 5 to the trolleys 3 and 4 is such that trolleys 3 and 4 are capable of some degree of independent motion on their respective members. In this embodiment, the mechanisms 8 and 9 interlink with U-shaped hooks 10 and 11, which attach to either end of the member 5 in a manner not shown. This permits the member 5 to swing in a plane perpendicular to its extent. A further trolley 6 of substantially similar characteristics to trolleys 3 and 4 is free to move linearly and rotationally on the member 5. The linear motion of trolleys 3 and 4 along the members 1 and 2, respectively, enables the member 5 to travel linearly. The capacity of trolleys 3 and 4 for independent motion (enabled by the non-rigidity of the attachment mechanisms 8 and 9) means that the member 5 is capable of rotation in a plane parallel with the floor.

(8) In this embodiment the trolleys 3,4,6 have face plates of the type 12 on both ends of the body. Any device (not shown) may be secured to the face plate 12 in any manner to cause the trolley 3,4,6 to rebound when it reaches the end of its respective member 1,2,5. This device could take the form, for example, of a spring, piston, or rubber buffer.

(9) In this embodiment the attachment 7 on trolley 6 provides a mounting system for attaching any training implement to the trolley 6, in such a way that the training implement may rotate about an axis perpendicular to the floor. This is shown in greater detail in FIG. 2.

(10) Referring to FIG. 3, illustrating a trolley of the kind 3,4,6, a metal housing 13 contains one or more pulley wheel(s) 14, with the radius of curvature of the profile of the pulley wheels being larger than or matching that of the cross-section of the supporting members 1, 2 and 5 respectively. The pulley wheel(s) 14 is constructed of a material with sufficiently low coefficient of friction that it may rotate in about the member upon which it sits with minimal impedance. In this embodiment the housing 13 is machined steel, but it is understood that other materials and construction techniques may be used. The pulley wheel(s) 14 rotate about an axle 15, which is secured to the housing 13 in a manner not detailed, but could include both ends of the axle being threaded and bolted on the outside of the housing 13. The free rotation of the pulley wheel(s) 14 is achieved in a manner not shown and/or by the use of a rotary bearing attaching the axle 15 to the pulley wheel(s) 14. This permits the trolleys 3, 4 and 6 to move smoothly along the members 1, 2 and 5, respectively. In this embodiment, the pulley wheel(s) 14 are maintained in a position central to the housing 13 by the use of spring washers 16 and 17, though it is understood that other means may be used. The housing 13 may contain at least one further pulley wheel 18 mounted to the housing 13 such that a member 1,2,5 may fit between the pulley wheels 14 and 18. The pulley wheel(s) 18 are mounted to the housing 13 by means of an axle 19. In this embodiment the axle 19 is mounted using the same mechanism as does axle 15, and the pulley wheel 18 is maintained centrally in the housing 13 by the same mechanism (not shown) as is pulley wheel(s) 14, though it is understood that different approaches not illustrated may be used. Zero or more eyelets 20 may be attached to the housing 13 of any trolley 3,4,6 in a manner not shown for any purpose including the attachment of zero or more elasticated cables (not shown in FIG. 1) which may be secured at the other end in any manner, including externally. In this embodiment, a single eyelet 20 is secured to the top of the housing 13.

(11) In this embodiment, the trolleys 3,4,6 are alike, however it is understood that they may differ in any respect, for instance the pulley wheel(s) may have profiles of different curvatures to account for the members 1,2,5 having different diameters.

(12) FIG. 4 shows a further example of the exercise system. In this example, the exercise system shown in FIG. 1 has been adapted. The training implement attached to the attachment 7 is an exercise device 42. A resilient restraining member 44 is attached at a first end to the trolley 6 and at a second end to a fixed point 46 relative to the first rigid member 1 and second rigid member 2. The resilient restraining member 44 may be a bungee cord attached to a ceiling, or any other resilient restraining member as described herein.
