Definitions
- This invention relates to exercise apparatus. It relates particularly to an exercise apparatus that is suited to being used in the home rather that a commercial fitness centre. Many users of exercise apparatus do of course have a multiple exercise unit in their home but these units are large and bulky and usually have to be situated in a special room, a bedroom or garage since they do not fit in well alongside conventional furniture pieces. There is therefore a requirement to provide exercise apparatus that would not look out of place in an ordinary home or office environment
- the present invention was devised to provide an exercise apparatus that would be able to exercise and tone as many muscle groups of the body as possible and thus to provide a complete training workout.
- Conventional machines which perform this function are usually tall in height and thus they do not have a compact shape that would blend well with conventional home or office future pieces.
- the invention attempts to provide a compact construction of multifunction exercise apparatus.
- an exercise apparatus having a seat portion and a backrest in the configuration of a chair, which in a first passive mode conceals the presence of a plurality of exercise elements which together form an exercise apparatus, and in a second exercise mode reveals one or more of said exercise elements for a user, the position of the seat portion being altered and locked in a position with respect to a base portion and support surface on which the apparatus stands when the apparatus is moved between its first passive mode and the second exercise mode.
- the seat portion may be raised and tilted to a position parallel to the support surface when the chair is altered from the first mode to said second exercise mode.
- the chair may include supporting frame elements which are interconnected operably to allow movement of the seat portion between said modes. At least two frame elements may interlock to provide a locking mechanism to secure the chair in said second exercise mode, the locking mechanism being releasable by a rotation of one of said frame elements.
- the exercise elements may be connected to a single resistance source which is adjustable to vary the resistance to movement encountered by a user at the exercise elements.
- the resistance source may comprise a set of freely mounted weights.
- the free weights may be movable along flexible guides which collapse from a taut condition when the chair is moved from its exercise mode to the passive mode.
- the resistance source may be selected from one or more resistance means such as springs, tension bands including rubber ropes, hydraulic or pneumatic cylinders, a set of free weights, electromagnetic resistance means, or dynamic friction mechanisms.
- the resistance source may be disposed centrally at a rear side of the backrest.
- the backrest may include a pair of opposed side panels which are capable of being opened to allow access to a pair of exercise elements adapted to operate together against a single resistance source.
- the exercise elements may include a ‘butterfly’ mechanism having a pair of butterfly arms each of which is rotatable about a secured pivot at elbow or arm support level against the resistance to movement provided by said resistance source.
- Each butterfly arm may include a constant resistance means effective to ensure the resistance to movement of the butterfly arms is substantially retained throughout the stroke.
- the connecting elements may be attached to resistance elements for use as a chest press exercise means.
- the backrest may include a centrally disposed support beam having attachment means for a ‘high pull’ exercise element having a resistance to movement provided by the said single resistance source.
- the seat portion may have an exposed front edge to which there is hingedly attached an exercise element movable against a resistance source, the exercise element being so shaped as to provide exercise regimes for two or more separate muscle groups.
- the hingedly attached exercise element may have an arc element piece or other elements attached to provide a downward force resisting upward movement.
- the exercise element may be securable in a fixed extended position and to which there is attachable a cycle crank mechanism having a pair of pedals connected via a rotatable shank, resistance to rotation of the pedals being provided by an adjustable friction sleeve.

A multifunction exercise apparatus having a seat portion (47) and a backrest (48) in the configuration of a chair, which in a first passive mode conceals the presence of a plurality of exercise elements which together form an exercise apparatus, and in a second exercise mode reveals one or more of said exercise elements for a user, the position of the seat portion (47) being altered and locked in a position with respect to a base portion and support surface on which the apparatus stands when the apparatus is moved between its first passive mode and the second exercise mode. This provides a comfortable chair construction that will fit in well with conventional home or office furniture when the apparatus is not required to be used for an exercise session.
Description
- This invention relates to exercise apparatus. It relates particularly to an exercise apparatus that is suited to being used in the home rather that a commercial fitness centre. Many users of exercise apparatus do of course have a multiple exercise unit in their home but these units are large and bulky and usually have to be situated in a special room, a bedroom or garage since they do not fit in well alongside conventional furniture pieces. There is therefore a requirement to provide exercise apparatus that would not look out of place in an ordinary home or office environment
- There have been earlier attempts to provide an exercise apparatus that was formed in the shape of a chair and one of these is disclosed in patent number U.S. Pat. No. 5,470,298. The patented apparatus provides means for carrying out a limited range of exercises which are directed to leg and arm movements. The apparatus does not require a long setting up procedure and thus it is convenient to be used at intervals during the day or else to remain as a functional item of furniture.
- The present invention was devised to provide an exercise apparatus that would be able to exercise and tone as many muscle groups of the body as possible and thus to provide a complete training workout. Conventional machines which perform this function are usually tall in height and thus they do not have a compact shape that would blend well with conventional home or office future pieces. The invention attempts to provide a compact construction of multifunction exercise apparatus.
- According to the invention, there is provided an exercise apparatus having a seat portion and a backrest in the configuration of a chair, which in a first passive mode conceals the presence of a plurality of exercise elements which together form an exercise apparatus, and in a second exercise mode reveals one or more of said exercise elements for a user, the position of the seat portion being altered and locked in a position with respect to a base portion and support surface on which the apparatus stands when the apparatus is moved between its first passive mode and the second exercise mode.
- The seat portion may be raised and tilted to a position parallel to the support surface when the chair is altered from the first mode to said second exercise mode. The chair may include supporting frame elements which are interconnected operably to allow movement of the seat portion between said modes. At least two frame elements may interlock to provide a locking mechanism to secure the chair in said second exercise mode, the locking mechanism being releasable by a rotation of one of said frame elements. The exercise elements may be connected to a single resistance source which is adjustable to vary the resistance to movement encountered by a user at the exercise elements. The resistance source may comprise a set of freely mounted weights. The free weights may be movable along flexible guides which collapse from a taut condition when the chair is moved from its exercise mode to the passive mode.
- The resistance source may be selected from one or more resistance means such as springs, tension bands including rubber ropes, hydraulic or pneumatic cylinders, a set of free weights, electromagnetic resistance means, or dynamic friction mechanisms. The resistance source may be disposed centrally at a rear side of the backrest.
- The backrest may include a pair of opposed side panels which are capable of being opened to allow access to a pair of exercise elements adapted to operate together against a single resistance source.
- The exercise elements may include a ‘butterfly’ mechanism having a pair of butterfly arms each of which is rotatable about a secured pivot at elbow or arm support level against the resistance to movement provided by said resistance source. Each butterfly arm may include a constant resistance means effective to ensure the resistance to movement of the butterfly arms is substantially retained throughout the stroke. The connecting elements may be attached to resistance elements for use as a chest press exercise means.
- The backrest may include a centrally disposed support beam having attachment means for a ‘high pull’ exercise element having a resistance to movement provided by the said single resistance source. The seat portion may have an exposed front edge to which there is hingedly attached an exercise element movable against a resistance source, the exercise element being so shaped as to provide exercise regimes for two or more separate muscle groups. The hingedly attached exercise element may have an arc element piece or other elements attached to provide a downward force resisting upward movement. The exercise element may be securable in a fixed extended position and to which there is attachable a cycle crank mechanism having a pair of pedals connected via a rotatable shank, resistance to rotation of the pedals being provided by an adjustable friction sleeve.

FIG. 1 , the exercise apparatus has the general appearance of an ordinary chair until it is required to be modified by a user to form the multifunction exercise unit. The apparatus is provided with achair seat 47, aback support 48 and arm rests 51. The arm rests can be fixed, pivoted or removable. -
FIG. 2 shows the basic structural components of the chair including a back frame upright element 41,lower support element 45,top element 62 and first pulley 6. An extendedtop element 33 carries asecond pulley 34. - A seat structure comprises a seat frame 40 (
FIG. 3 ) attached to the back frame upright element 41 and which carries apivot housing 15 for supporting butterfly arms. Theseat frame 40 has an extension element arranged for enabling the length of the seat to be increased when the apparatus is arranged in the exercise mode. - A lower base support element 42 (
FIG. 3 ) which is attached by ahinge 46 to thelower support element 45 also is provided with afront support element 43. Anadjustable height element 36 is attached between the lowerbase support element 42 and theseat frame 40. - The extended top element 33 (
FIG. 3 ) is raised and secured in a position above the back of the chair and having thesecond pulley 34 is attached to the top extremity. - A butterfly arm element consists of a pivot housing 15 (
FIG. 7 ) carrying a butterfly pivot rod 65 (FIG. 9 ) and fixed to theseat frame 40. Thebutterfly pivot rod 65 is connected to the butterfly arm 10 (FIG. 9 ) having a separate cable spacer arm 11 pivoted to it. The vertical piece of the butterfly arm is a hollow section and this houses an adjustable butterfly handgrip 66. Thebutterfly arm 10 is also connected to the cable spacer arm 11 by means of a connecting link 9 which serves to pull the cable spacer arm rotating on a vertical axis. The cable spacer arm 11 has twovertical anchor rods 14 where the cable 16 (FIG. 9 ) passes through. Thecable 16 passes through acable stop 12 and with a simple fixing this is held in position along thecable 16. When the butterfly module is used, force is exerted against forearm pads 13 (FIG. 8 ) that in turn rotate the cable spacer 11 via the connecting link 9. The cable spacer arm 11 allows the force exerted on thebutterfly arm 10 to be kept relatively constant, as thearm 10 rotates allowing thecable 16 to be kept at a constant radius from the pivot point. As the arm 11 rotates it pullscable stop 12 and pulls thecable 16, which is connected to a floatingpulley 17. The floatingpulley 17 is connected tocable 35, it transmits the force to the weight stack by the connection 7 and cable 8 (FIG. 10 ). - The pectoral bar 25 (
FIG. 7 ) or handgrip 81 can be attached to ahook 26 on thecable 16 which passes through theanchor rods 14. When thepectoral bar 25 or handgrip 81 is pushed forward, the force exerted is transmitted to the weight stack by means ofcable 16, floatingpulley 17 tocable 35.Cable 35 is joined to the connection 7 coupled to cable 8 which is connected to a weight stack pick-up rod 3 and the force is thus transmitted to the weight stack. - A stomach exercise effect is achieved by pushing the
pectoral bar 25 forward against the bar with the user's chest. Thepectoral bar 25 and handgrip 81 can then be disconnected when not in use. - A leg extension element is provided by a front extension element 22 (
FIG. 4 ) andmember 23 with an elbow joint along its length and hinged at its upper extremity to theseat extension element 28. This hinge allows thefront extension element 22 to swing freely when the apparatus is in exercise mode. Attached to thefront extension element 22 is a cable spacer piece 24 (FIG. 7 ) which rotates as thefront extension elements 22 rotate. Afront cross bar 29 is attached to the front extension member 23 (FIG. 4 ). The front cross bar 29 (FIG. 5 ) has a protective material cushioning the user's ankles when in use. Thefront cross bar 29 can be extended or retracted according to the leg length of the apparatus user by means of a thumb screw 39. When theextension elements FIG. 4 ) is attached to the elbow of thefront extension element 22 which serves to pull it in a downward direction. - A biceps curl exercise is achieved by lifting the
front cross bar 29 which acts as a handgrip bar for this exercise. As the handgrip is pulled upwards, the force exerted is transmitted to cable 8 which passes under thecable spacer piece 24 keeping it at a constant radius from thehinge 27. The cable spacer piece allows a constant force to be felt by the apparatus user as the extension elements are raised. The force on cable 8 is then transmitted to the weight stack pick-up rod 3 which in turn lifts the weight stack. - A rowing exercise is achieved by pulling the
front cross bar 29 away from the chair structure while the apparatus user is seated on the floor. As thecross bar 29 is pulled away from the chair, force is exerted to cable 8 which is then transmitted to the weight stack pick-up rod 3 which in turn lifts the weight stack. - The weight stack 1 (
FIG. 10 ) is of a conventional construction comprising a stack of rectangular weights slide-mounted on to a pair ofvertical guides 4. Each weight is provided with a central horizontal hole registering with a respective hole in the weight stack pick-up rod 3. The central pick-up rod 3 has a lift cable 8 attached and this passes over the first pulley 6. The amount of weight to be lifted is selected by engaging alock pin 2 through the appropriate hole in the weight stack and then into the pick-up rod 3. Thus when the cable is adequately tensioned the selected number of weights in the stack will be lifted. - The cable function depicted in
FIG. 10 comprises five cables namely, cable 8, connected to the weight stack pick-up rod 3 passing over the first pulley 6, down under thepulley 18 topulley 21 onto the leg extension module and being connected tofront extension member 23.Cable 35 is joined to cable 8 by a connection 7 which can be simply a ring connected to cable 8.Cable 35 is joined to connection 7 then passes down under pulleys 19 and 20 and is connected to a floating pulley coupling 17 (FIG. 10 ).Cable 16 passes through the floatingpulley 17 overpulley 5 and has ahook 26 at each of the extremities of thecable 16. Thehook 26 is attached to each end of thepectoral bar 25, or hand grips 81 (FIG. 7 ) by means of a ring fastening. When thepectoral bar 25 or handgrip 81 is pushed forward, force is transmitted fromcable 16 tocable 35 via floatingpulley 17 which is connected to cable 8 via connection 7. The force is then transmitted to the weight stack pick-up rod 3 where the appropriate number of weights is lifted.Cable 16 has acable stop 12 secured along each side of its length (FIG. 10 ) which is secured ontovertical anchor rods 14 fixed to the cable spacer arm 11. When theforearm pad 13 is rotated in a forward direction, it rotates the cable spacer arm via connecting link 9 and transmits the force to the weight stack as described above.Cable 31 is also connected to the weight stack pick-up rod 3 (FIG. 10 ) and toconnection 36. When the extendedtop element 33 is attached to the upper support bearing beam asecond cable 31 a is joined tocable 31 via aconnection 36 and then travels over thesecond pulley 34 and to a hook or connection on thehigh pull bar 32. When the high pull bar is pulled downwards force is transmitted viacable 31 a and throughcable 31 to theweight stack 1 as described. - The basic upholstery arrangement of the exercise apparatus includes a padded side panel 49 (
FIG. 3 ) which is fixed to the back frame upright element 41 withside panels 50 that are made to be hinged, rotated or removable to give access to the butterfly elements. The back support 48 (FIG. 3 ) is secured to the back frame element and the seat frame element and is padded or suitably upholstered. Thechair seat 47 is a normal firm padded seat which can slide forward with the extended seat element The arm rests 51 of the chair can be hinged or removed when the apparatus is required for use in the exercise mode. When the butterfly mechanism has been stowed away, the side panels 50 (FIG. 3 ) can be placed in position and the exercise apparatus becomes converted to a chair. -
FIG. 11 shows an alternative embodiment of the exercise apparatus where, when not required for training purposes, the apparatus can have the appearance and use of a conventional comfortable armchair. - The exercise apparatus comprises a strong-ridged base frame 153 (
FIG. 22 ) and a strong-ridgedseat frame 154. The base frame and seat frame are secured together by rotatingextension arms 155 and 172 (FIG. 16 ) and held in the raised position by lockingarms 156. The locking mechanism consists of asquare section bar 167 placed across the base frame 153 (FIG. 16 ) which rotates by means of a pull arm 169 or a handle 192 (FIG. 16 ). The locking arm has a square section cut out which locks onto thebar 167 when lifted up to exercise mode. A spring 157 (FIG. 16 ) forces the lockingarms 156 back onto thesquare section bar 167 securing the seat in an exercise mode. Thesquare section bar 167 has anextension piece 168 attached at either side of the bar where the locking bar is positioned, and when thesquare bar 167 is rotated it forces the locking arm free from the square bar allowing theseat frame 154 to be lowered onto thebase frame 153 and base side structures. To raise the seat frame it is simply lifted up from the back, and it is automatically held in position by the lockingarms 156 as they lock into position. The rear rotating extension arms are longer than the front rotating extension arm allowing the back of the seat frame to rise higher than the front of the frame. - The
rear extension arms 155 have a mechanism such as a spring, gas strut, rubber band or hydraulic lift 176 (FIG. 17 ) attached to the lower end and to theside base frame 158 in order to counterbalance the weight of the seat thus making it easier to lift - There are two
side base structures 158 and twoside structures 159 as shown inFIG. 17 . Theside base structures 158 are fixed to the base frame 153 (FIG. 17 ) and theside seat structures 159 are secured to theseat frame 154. Attached to theside base structures 158 at the lower edge is a pulley wheel bar 175 (FIG. 12 ), with twopulley wheels 120, 121 (FIG. 20 ) attached to its centre position. Also attached at the lower edge of theside base structures 158 is a weightstack support frame 174 withpulley wheels 118, 119 (FIG. 20 ) attached centrally. There are heavy-duty wheel castors 193 (FIG. 12 ) also secured to the lower edge of the side base structure, which allows the chair to be easily moved. Theside seat structures 159 are of an L-shape, and a vertical back 160 (FIG. 19 ) is attached to its vertical edge stabilizing the structure. Attached to the top of the L-shaped side seat structure is an upper load bearing support frame 162 (FIG. 18 ) which is also secured to thevertical back 160. The upperload bearing frame 162 consists of a rectangular frame with a pulley wheel 106 (FIG. 18 ) between the frame at its centre position and parallel to the side seat structure. The rear member of the upper load bearing support frame is a load-bearing beam having a hole in its central position. There are two flexible weight guides secured at the top extremity to the load-bearing beam by means of the clamps 163 (FIG. 18 ). The lower extremity of the flexible weight guide is secured to the weight stack support frame, which is fixed to the base side structure. When the chair is lifted and locked into the exercise mode, the flexible guides become tight and taut allowing the weights to slide freely up and down their length. - A high pull extension piece 133 (
FIG. 18 ) is secured to the centre of a load bearing beam which forms the back of the load bearing frame 142 (FIG. 18 ). The high pull extension piece consists of a rod or bar secured at its lower extremity into the hole of the load bearing beam and having a pulley wheel 134 (FIG. 20 ) attached to the top extremity. - A butterfly arm mechanism comprises a pivot housing 115 (
FIG. 18 ) having a friction insert, housing the butterfly pivot rod 165 (FIG. 19 ) and fixed to the side of the L-shapedseat structure 159. Thepivot rod 165 is connected to the butterfly arm 110 (FIG. 19 ) having a separate cable spacer arm 111 (FIG. 18 ) pivoted to it. The vertical piece of the butterfly arm is a hollow section and houses anadjustable butterfly handgrip 166. Thebutterfly arm 110 is also connected to thecable spacer arm 111, by means of a connectinglink 109 which pulls the cable spacer arm rotating on a vertical axis aboutpivot point 165 a in a circular motion. Thearm 111 has twovertical anchor rods 114 where the cable 116 (FIG. 18 ) passes through. Thecable 116 passes through acable stop 112 which with a simple fixing is held in position along thecable 116. When the butterfly module is used, force is exerted against forearm pads 113 (FIG. 20 ) that in turn rotatescable spacer 111 via the connectinglink 109. Thecable spacer 111 allows the force exerted onbutterfly arm 110 to be relatively constant, as thearm 110 rotates allowing thecable 116 to be kept at a constant radius frompivot point 165 a. As thearm 111 rotates it pullscable stop 112 and pullscable 16, which is connected to a floatingpulley 17. The floating pulley 117 connected tocable 135, transmits the force to the weight stack byconnection 107 and cable 108 (FIG. 20 ). - A
pectoral bar 125 orhandgrip 181 can be attached to ahook 126 on thecable 116 which passes throughanchor 114. When thepectoral bar 125 orhandgrip 181 is pushed forward, the force exerted is transmitted to the weight stack viacable 116, coupling the floating pulley 117 tocable 135.Cable 135 is connected tocables rod 103 and the force is thereby transmitted to the weight stack. - A stomach exercise is achieved by pushing the
pectoral bar 125 forward against the bar with the chest. Thepectoral bar 125 andhandgrip 181 can then be disconnected when not in use. - A leg extension mechanism as depicted in
FIG. 13 comprises twoparallel extension arms 122 and a hollow tubularfront extension arm 123 connected inside the two arms by anelbow pivot 140. The top of thearms 122 is attached to thefront member 128 of theseat frame 154 by means of ahinge 127. This hinge allows the two arms to swing freely when in exercise mode. Attached toextension arms 122 is a cable spacer piece 124 (FIG. 20 ) which rotates as thearms 122 rotate. Atee piece 129 slides inside the extension arm 123 (FIG. 13 ). The front cross bar is provided with a protective material cover for cushioning the user's ankles when the apparatus is in use. Thetee piece 129 can be extended or retracted according to the leg length of the apparatus user by adjustment of athumb screw 139. The feet of the exercise apparatus user may be hooked under thefront cross bar 129 and raised and lowered against the resistance of the weight stack viacable 108. When theextension arms instep foot bar 130 pivoting on swivel arms 173 (FIG. 13 ) is placed under the cross bar and this provision serves to keep the tee piece in a constant position on the user's ankle. - For a biceps curl exercise, the
instep foot bar 130 is lifted and this component then also acts as a handgrip bar for this exercise. As the handgrip is pulled upwards the force exerted is transmitted tocable 108 which passes under thecable spacer arm 124 keeping it at a constant radius from thehinge 127. The cable spacer piece allows a constant force to be felt by the apparatus user as the extension arms are raised. The force oncable 108 is then transmitted to the weight stack pick uprod 103 which in turn lifts the weight stack. - A rowing exercise is achieved by pulling the
instep bar 130 away from the chair while the apparatus user is seated on the floor. As theinstep bar 130 is pulled away from the chair, force is applied tocable 108 which is then transmitted to the weight stack pick uprod 103 which in turn lifts the weight stack - A bicycle attachment can be connected to the leg extension module as shown in
FIG. 14 . Thebar 150 is of a square section material usually metal having a connection lug 149 attached. This connection lug slots into the square hollowsection extension arm 123. Thebar 150 is held in position on the twoarms 122 by a bolt with a hand turn knob 147 passing through thebar 150 and tightened with cross plates 147 a onto thearms 122. The pedal arm is a Z-shape with rod 151 being held onto a slidingtube 181 by aclamp turn bolt 148. The rod has twostandard bicycle pedals 152 attached on either side of the rotatable crankshaft. The crankshaft formed by the rod 151 passes through afriction sleeve 180 and as theturn bolt 148 is tightened the friction on the crankshaft will increase thus causing the apparatus user to apply a greater physical force to turn thepedals 152. Thetube 181 slides alongbar 150 to allow the apparatus user to adjust the position of the pedals to suit the individual leg length. Thetube 181 is kept in position alongbar 150 by a turn bolt 178 (FIG. 15 ). -

Each weight having a central horizontal hole registering with a respective hole in the pick-uprod 103. The central pick-up rod has alift cable 108 attached which passes over apulley wheel 106. The amount of weight to be lifted is selected by engaging alock pin 102 through the appropriate hole in the weight stack and into the pick-uprod 103. Thus when the cable is adequately tensioned the selected number of weights in the stack will be lifted. - The cable function depicted in
FIG. 20 comprises mainly five cables which arecable 108, connected to the pick-uprod 103 passing over thepulley wheel 106 down under thepulley wheel 118, topulley wheel 121 onto the leg extension module and connected tofront extension tube 123.Cable 135 is connected tocable 108 by acoupling 107, which can be a simple ring fastened tocable 108 where thecable 135 is fastened.Cable 135 is connected tocoupling 107, then passes down underpulleys FIG. 20 ).Cable 116 passes through the floating pulley 117 overpulley 5 and has ahook 126 at each of the extremities of thecable 116. Thehook 126 is attached to each end thepectoral bar 125 or hand grips 181 (FIG. 18 ) by means of a ring fastening. When thepectoral bar 125, or hand grips 181 is pushed forward, force is transmitted fromcable 116 tocable 135 via floating pulley 117 which is connected tocable 108 viaconnection 107. The force is then transmitted to pick uprod 103 where the appropriate number of weights is lifted.Cable 116 has acable stop 112 secured along each side of its length (FIG. 20 ) which hooks ontovertical anchor rods 114 fixed to thecable spacer arm 111. When thebutterfly press pad 113 is rotated in a forward direction, it rotates the cable spacer arm via connectinglink 109 and transmits the force to the weight stack as described above.Cable 131 is also connected to pick up rod 103 (FIG. 20 ) and toconnection 136. When the highpull extension piece 133 is attached to the upper support bearing beam asecond cable 131 a is connected tocable 131 via acoupling 136 and then travels overpulley wheel 134 and to a hook or connection on thehigh pull bar 132. When the high pull bar is pulled downwards, force is transmitted viacable 131 a and viacable 131 to theweight stack 1 as described. - The basic upholstery of the exercise apparatus armchair is a padded
side panel 182, 183 (FIG. 21 ) fixed to theside base structure 158 and to the side seat structure 169 and covered with an upholstery material. The back support 160 (FIG. 21 ) is secured to the vertical edge of theseat side structure 159 and anupholstered panel 186 attached thereto forming the padded back of the exercise chair. The side flaps 190 conceal theback panel 159 a and thebutterfly arms 110. The side flaps are flexibly hinged at the lower edge to the outside arm of the chair, and held in position by the upholstery material on theback panel 186. The seat of the chair is a normal firmconventional cushion 185 placed onto theseat frame 154. The top portion of the backrest 187 (FIG. 21 ) consists of an upholstered top panel secured to the load bearing frame with an opening at its centre for the high pull extension piece. A specially shaped cushion 188 is placed over the arms of the chair to conceal the butterfly rod housing. A fixing piece 191 is secured to thefront member 128 of the seat frame 154 (FIG. 12 ) to which the front upholstered panel or material 189 is fastened concealing the leg extension mechanism. Theback panel 159 a (FIG. 18 ), the top upholstered panel 187, the padded backpanel 186, and side arms 183 (FIG. 21 ) form a recess at the rear of thebackrest 160 where all of the butterfly mechanism can be stowed away. When the butterfly mechanism is thus stowed, the side flaps 190 (FIG. 21 ) can be placed in position and the exercise apparatus has been converted again to an armchair configuration. The exercise apparatus of the invention has been found to provide a practical construction of machine that may be built at a reasonable cost. The invention provides an armchair that does not look out of place in a living room or office but which can be transformed into an exercise machine within seconds. The seat of the chair lifts up and it is locked in position for performing multiple exercises, and thus exercising most of the body muscle groups in a normal workout. Each exercise routine operates independently and the apparatus enables many routines to be performed that are normally undertaken only on a much larger machine. When the apparatus is not in use, it is simply lowered down and it returns to the appearance of a comfortable armchair. - The foregoing description of embodiments of the invention has been given by way of example only and a number of modifications may be made without departing from the scope of the invention as defined in the appended claims. For instance, the vertical guides which serve to retain the weights of the
weight stack 1 in alignment with one another, could be replaced by end or corner guides which are located adjacent to the outer edges of the weights
