(74) In use, the first bar member 300 can be rotated relative to a vertical axis. The first bar member 300 can also be horizontally and vertically moved.

(75) As the first bar member 300 is moved vertically with respect to the longitudinal axes of the vertical members, the first bar member mounting portions 330 slide vertically along the respective mounting rail portions 240 of the vertical members 200.

(76) As the first bar member 300 is moved horizontally in a direction parallel to the longitudinal axes of the paired base assemblies 100, the respective vertical member mounting portions 130 slide horizontally along the respective movable horizontal member rails 112.

(77) As the first bar member 300 is moved horizontally in a direction perpendicular to the longitudinal axes of the paired base assemblies 100, the respective movable horizontal members 110 slide horizontally along the respective stationary horizontal member rails 122.

(78) As the first bar member 300 is rotated about a vertical axis, for one or more of the paired base assemblies 100 the respective vertical member mounting portion 130 slides horizontally in a first direction along the respective movable horizontal member rails 112; and the respective movable horizontal member 110 slides horizontally in a second direction substantially perpendicular to the first direction along the respective stationary horizontal member rails 122.

(82) As the first bar member 300 is rotated about a vertical axis, the mounting rail engaging channel blocks 551 of the upper bar assembly 500 rotate about the respective mounting rail portions 240 of the vertical members 200.

(83) In embodiments (as pictured in FIGS. 6 and 7) wherein the first bar member 300 comprises a hammer 350, and one or more of the first bar member mounting assemblies 330 comprise a hook member 332; switch 333 in first form 333-I; and an actuator in the form of a linear solenoid (not shown), rotation of the first bar member about its longitudinal axis in a first direction causes hammer 350 to actuate switch 333-I in a first manner by depressing switch 333-I.

(84) Additionally, when switch 333-I is depressed by hammer 350, rotation of the first bar member about its longitudinal axis in a second direction opposed to the first direction causes hammer 350 to actuate switch 333-I in a second manner by releasing switch 333-I

(85) In use, upon actuation of the switch 333-I in the first or second manner, the actuator in the form of linear solenoid moves with respect to hook member 332 whereby the aperture engaging end 332A moves with respect to the web portion 230 of vertical member 200.

(86) As pictured, actuation of switch 333-I in the first manner by depressing switch 333-I moves the linear solenoid with respect to hook member 332 whereby hook member 332 moves towards the web portion 230 of vertical member 200, and is capable of engaging with any one of the plurality of apertures 231.

(87) As pictured, actuation of switch 333-I in the second manner by releasing switch 333-I moves the linear solenoid with respect to hook member 332 whereby the hook member 332 moves away from web portion 230 of vertical member 200, and can disengage with apertures of web portion 230.

(88) However, it will be appreciated that the particular arrangement of actuation of switch 333-I by hammer 350 in relation to engagement of hook member 332 with apertures 231 can be varied as desired.

(89) In embodiments (as pictured in FIG. 8) wherein the first bar member comprises actuating cable 370, movement of actuating cable 370 with respect to the bar member user engaging portion 310 can actuate switch 333 which is in a second form 333-II.

(90) As pictured, in use, when cable 370 is released from bar member user engaging portion 310, switch 333-II is actuated in a first manner, and the linear solenoid moves with respect to hook member 332 such that hook member 332 moves towards the web portion 230 of vertical member 200, and is capable of engaging with any one of the plurality of apertures 231.

(91) As pictured, in use, when cable 370 is held against bar member user engaging portion 310, switch 333-II is actuated in a second manner, and the linear solenoid moves with respect to hook member 332 such that hook member 332 moves away from web portion 230 of vertical member 200, and can disengage with an apertures 231 of web portion 230.

(92) However, it will be appreciated that the particular arrangement of actuation of switch 333-II by cable 370 in relation to engagement of hook member 332 with apertures 231 can be varied as desired.

(93) In some embodiments wherein main load receiving assembly vertical member engaging portion 410 of load receiving assembly 400 comprises locking mechanism 4100 (as pictured in FIG. 9), actuation of switch 333 moves the actuator of locking mechanism 4100 in the form of linear solenoid 4130.

(94) However, it will be appreciated that in other embodiments, movement of linear solenoid 4130 of locking mechanism 4100 may be signalled in another suitable manner. For example, actuation of another switch (not shown) instead of or as well as switch 333 may be required to move linear solenoid 4130 of locking mechanism 4100.

(95) As depicted in FIG. 9, movement of linear solenoid 4130 relative to load receiving assembly locking mechanism engagement member 4110 moves load receiving assembly locking mechanism engagement member 4110 moves relative to portion 230 of vertical member 200. It will be appreciated that locking mechanism engagement member can thereby engage or disengage with apertures 231 of web portion 230 of vertical member 200, substantially as described hereinabove in regard to hook member 332 of first bar member mounting portion 320.

(96) In some embodiments, actuation of switch 333 in a first manner to configure hook member 332 to engage with web portion 230 also configures load receiving assembly locking mechanism engagement member 4110 to engage with web portion 230.

(97) In some embodiments, actuation of switch 333 in a second manner to configure hook member 332 to disengage with web portion 230 also configures load receiving assembly locking mechanism engagement member 4110 to disengage with web portion 230.

(98) However, as hereinabove described, in some embodiments movement of linear solenoid 4130 of locking mechanism 4100 is signalled in another suitable manner. It will be appreciated that, in these embodiments, signalling of the actuator in another suitable manner, e.g. by actuation of another switch (not shown) instead of or as well as switch 333, may be required to configure load receiving assembly locking mechanism engagement member 4110 to engage and/or disengage with web portion 230.

(99) In embodiments (as pictured in FIG. 1) wherein the first bar member 300 comprises one or more hooks 360 and the vertical members 200 comprise a plurality of spaced vertical catches 220B, in use the hooks 360 of the first bar member 300 may be engaged with any one of the pairs of spaced vertical catches 220B by rotation of the first bar member 300 about its longitudinal axis.

(100) In use, the load receiving assemblies 400 can be moved horizontally and vertically.

(101) As the one or more load receiving assemblies is moved vertically, the respective pairs of load engaging assembly channel blocks 412 slide along the respective pairs of vertical member mounting rails 250.

(102) As the one or more load receiving assemblies are moved horizontally in a direction parallel to the longitudinal axes of the paired base assemblies 100, the respective vertical member mounting portions 130 slide horizontally along the respective movable horizontal member rails 112.

(103) As the one or more load receiving assemblies are moved horizontally in a direction perpendicular to the longitudinal axes of the paired base assemblies 100, the respective movable horizontal members 110 slide horizontally along the respective stationary horizontal member rails 122.

(104) The first bar member 300 can be operatively engaged with one or more of the load receiving assemblies 400. For operative engagement, the connecting member engaging portion 334 of the first bar member mounting portion 330, and a connecting member engaging portion (not shown) of the respective load receiving assembly 400, are engaged with a connecting member (not shown) e.g. a cable or rope.

(105) When connected, the first bar member 300 and the one or more load receiving assemblies 400 can be used in a counterbalance arrangement.

(106) In one embodiment wherein a user engages with the user engaging portion 310 of the bar member 300, a force exerted downwardly by the one or more load receiving assemblies 400, e.g. by mounting one or more weights onto the load receiving bar member 431, reduces the force required from a user to move the first bar member 300 upwardly.

(107) In another embodiment wherein a user engages with one or more of the load receiving assembly user engaging portions 440, a force exerted downwardly by the first bar member 300, e.g. by mounting one or more weights onto the load receiving portions 320, reduces the force required from a user to move the one or more load receiving assemblies 400 upwardly.

(108) In another embodiment wherein a user engages with one or more of the user engaging portions 540 of the upper bar assembly 500, and the user's body weight exerts a downward force on the first bar member 300, a force exerted downwardly by the one or more load receiving assemblies 400 exerts an upward force on the on the first bar member 300, and thereby reduces the force required from a user to move the user's body upwards towards the user engaging portions 540.

(109) In use, the position of one or both of the paired user engaging portions 540 relative to the longitudinal axes of the upper bar 510 and the lower bar 520 can be adjusted by sliding the user engaging portions along the upper bar 510.

(110) Upon application of a downward force by a user, the paired user engaging portions 540 are stably supported by the lower bar 520.

(111) In use, the locking assemblies (not shown) of the respective stationary horizontal members 120 of the base assemblies 100 can be engaged to constrain horizontal movement of the first bar member 300 and/or one or more of the load receiving assemblies 400 in a direction perpendicular to the longitudinal axes of the paired base assemblies 100. When said locking assemblies are engaged, the exercise apparatus may be used like a dual action Smith machine.

(112) In use, the locking assemblies 133 of the vertical member mounting assemblies 130 of the base assemblies 100 can be engaged to constrain horizontal movement of first bar member 300 and/or one or more of the load receiving assemblies 400 in a direction parallel to the longitudinal axes of the paired base assemblies 100. When said locking assemblies are engaged, the exercise apparatus may be used like a normal Smith machine.

(113) Advantageously, the exercise apparatus 10 allows a user to rotate the first bar member about a vertical axis, in addition to allowing a user to move the first bar member horizontally and vertically. This provides a user with additional freedom of movement for exercises, e.g. bench presses, squats, and lunge exercises. The exercise apparatus 10 therefore provides freedom of movement similar to that provided by a free barbell, but also provides the additional safety of a bar member that is mounted to guides, i.e. the paired vertical members 200.

(114) Another advantage of the exercise apparatus 10 is that it is highly adaptable and configurable, facilitating a wide range of exercises. By way of non-limiting example, the first bar member 300 can be used to perform bench presses, squats, and lunges; one or more of the load receiving assemblies can be used to perform press-up or pull-down exercises; and the upper bar assembly user engaging portions 540 can be used to perform pull-up or chin-up exercises.

(115) Another advantage of the exercise apparatus 10 is that it facilitates partial assistance for various exercises performed by a user. As hereinbefore described, operative engagement between the first bar member 300 and the load receiving assemblies 400 can be used to offset the force required to perform various exercises facilitated by the exercise apparatus 10. This may be particularly beneficial to allow a more inexperienced user to perform exercises using the exercise apparatus 10.

(116) Yet another advantage of the exercise apparatus 10 is that it can be locked to constrain various movements of the first bar member and/or load receiving assemblies. Where desired by a user, this allows the exercise apparatus 10 to be used as a dual action Smith machine, or a normal Smith machine, as hereinbefore described.

(117) Additionally, embodiments wherein the first bar mounting assemblies 330 comprise a locking device as pictured in FIGS. 6 and 7, and or the load receiving assemblies 400 comprise a locking device as pictured in FIG. 9 can be particularly advantageous. Notably, such locking devices can allow for first bar member 300 and/or load receiving assemblies 400 to be constrained from movement by a user during easily use, by actuation of switch 333.

(118) This can be particularly advantageous from a safety perspective. It can also potentially obviate the need for an assistant or spotter during use of exercise apparatus 1.
