Definitions
- This invention relates to adjustable furniture, for example to chairs or beds or the like in which the position of one weight or load carrying part of the furniture can be moved relative to another.
- the adjustment may be motorized or alternatively may be achieved manually.
- Adjustable chairs are well known in which the angle of the seat back can be changed in order to provide a recline position and/or in which a movable foot rest is provided. Chairs of this type are available in which adjustment is achieved manually or in a motorized fashion. Some motorized chairs have the ability to incline the seat of the chair to assist the user in moving from a seated position to a standing position. Adjustable beds are also known in which a head and upper back supporting region of the bed can be moved to adjust the inclination thereof.
- the movable parts of such items of furniture are supported upon relatively complex, typically steel, support arrangements, often including a series of linkages movable to allow the movable part of the piece of furniture to travel through its desired range of movement.
- support arrangements are often costly and heavy, making transportation, handling and use awkward, and place severe restrictions on the designs of furniture which are available.
- an adjustable furniture comprising a first furniture component, a second furniture component movable, in use relative to the first furniture component and supported by a guide arrangement comprising a guide associated with one of the first and second components and at least one follower associated with the other of the first and second components and movable along the guide.
- adjustable furniture comprising a first furniture component, a second furniture component movable, in use, relative, to the first furniture component and supported by a guide arrangement comprising a guide associated with one of the first and second components and at least one follower associated with the other of the first and second components and movable along the guide.
- At least two followers are provided, the followers being in a fixed relationship to one another.
- the guide conveniently comprises an elongate slot or groove in which the follower(s) are located.
- the follower(s) conveniently comprise rollers.
- the guide could, alternatively, comprise a guide rail or the like secured to the said one of the first and second components.
- the guide for example in the form of an elongate slot, or groove, may be of arcuate form, having a fixed radius of curvature, to guide the first and second components for relative pivoting-like movement about a pivot axis located at the centre of curvature of the guide.
- the guide may be of, for example, part elliptical form or be of a more complex shape.
- the first and second components may comprise one or more of the base of the chair, the seat pad, the seat back, the foot rest or other supporting part of the chair.
- the components may comprise parts thereof which are relatively movable and which, in use, are adapted to bear at least part of the weight of the user of the furniture.
- an article of furniture comprising an outer support, and inner support guided for movement relative to the outer support, and back support guided for movement relative to both the inner support and the outer support.
- the inner, outer and back supports may be guided for movement using any of the arrangements described hereinbefore.
- the inner support may comprise, for example, a seat pad support.
- the arrangement is such that the seat pad support and back support move simultaneously between an upright configuration and a reclined configuration. In the reclined configuration, the back support does not project significantly further rearward of the furniture than when in its upright configuration.
- the furniture is thus of “zero-wall” form.
- the furniture may be manually driven between its upright and reclined configurations, or alternatively may be motorized.
- a footrest for example of the type described hereinbefore, may be provided, the footrest being movably mounted to the inner support. It may be manually movable or alternatively may be motorized. Preferably a single motor is used to drive the furniture between its upright and reclined configurations and to drive the footrest. For example, from an upright configuration, an initial part of the motor operation may drive the footrest, a final part of the operation driving the furniture to its reclined configuration
- FIG. 1 illustrates an adjustable chair in accordance with one embodiment of the invention.
- FIG. 2 illustrates some of the components of the chair of FIG. 1 .
- FIGS. 3 and 4 illustrate alternative designs of chair.
- FIG. 5 illustrates, diagrammatically, part of an arrangement suitable for use in the chairs of FIGS. 1 to 4 .
- FIG. 6 is a diagrammatic view of a piece of furniture in accordance with one embodiment of the invention.
- FIG. 7 is a diagrammatic view illustrating one side of the piece of furniture.
- the chair illustrated in FIGS. 1 and 2 is an adjustable chair of the motorized form and comprises a number of relatively movable chair components.
- the chair comprises a seat pad component 10 which is angularly movable between a position in which it lies generally horizontally (as shown), and a tilted or inclined position in which it is raised to assist a user in moving from a seated position to a standing position.
- the chair further comprises an adjustable back rest component 12 and an adjustable foot rest component 14 .
- the seat pad 10 comprises a pair of side support members 16 between which is secured a seat pad support member 18 , the upper surface of which carries a suitably padded and upholstered cushion 20 .
- the support members 16 each carry two pairs of rollers 22 which, in use, are able to ride within arcuate guide grooves 24 provided in side members 26 of a base component 28 .
- the base component 28 and seat pad 10 include respective motor mounting brackets 30 , 32 between which a suitable actuator (not shown) is connected. It will be appreciated that if the actuator connected between the brackets 30 , 32 is operated to move from a retracted condition in which the seat pad 10 occupies substantially the position illustrated to an extended condition, then the seat pad 10 will be moved, the rollers 22 acting as followers, being guided for movement within the respective arcuate grooves 24 to cause the seat pad 10 to move from the generally horizontal position illustrated to an inclined position, the seat pad 10 moving through a pivot-like motion about a pivot point defined by the centre of curvature of the two arcuate grooves 24 .
- the side members 16 are each provided with an arcuate groove 34 within which a pair of rollers 36 carried by a bracket 38 can move, the bracket 38 serving to support the seat back 12 . It will be appreciated, therefore, that the seat back 12 is guided for pivot-like movement relative to the seat pad 10 about a pivot point located at the centre of curvature of the arcuate groove 34 .
- the bracket 38 and side members 16 are provided with mounting brackets 40 between which an actuator is connected and, as with the seat pad 10 , adjustment of the length of the actuator causes the rollers 36 to move within the arcuate groove 34 to adjust the angle of inclination of the seat back 12 .
- the foot rest 14 is mounted upon a bracket 42 having a pair of rollers 44 secured thereto, the rollers 44 being located within an arcuate groove 46 formed in the side member 26 of the base component 28 .
- the bracket 42 further serves as a mounting bracket for a motor device, the other end of which is secured to a mounting bracket 48 associated with the base component 28 to drive the foot rest 42 between a substantially vertical orientation as illustrated in FIGS. 1 and 2 and a substantially horizontal configuration.
- a user can operate the motors of the chair to cause the foot rest 14 to be driven from the position illustrated towards a substantially horizontal configuration, the rollers 44 riding within the guide groove 46 to support and guide the foot rest 14 through such movement.
- the back rest can be adjusted between the substantially vertical position illustrated and a reclined position by operation of the appropriate motor to cause the rollers 36 to ride along the length of the arcuate groove 34 , the rollers 36 and groove 34 serving to guide and support the back rest 12 through such movement.
- the movement of the foot rest 14 may be controlled independently of the movement of the back rest 12 , if desired.
- the seat pad 10 may be moved to an inclined position, the rollers 22 moving within the arcuate grooves 24 to guide and support the seat pad 10 through such movement, the movement of the seat pad 10 serving to assist a user in moving from a seated position towards a standing position.
- the position of the seat back 12 relative to the seat pad 10 may also be adjusted so as to ensure that the position of the seat back 12 does not interfere with the movement of the user towards a standing position.
- the chair can be of improved comfort to the user.
- the seat pad 10 it is desirable for the seat pad 10 to follow a pivot-like course of movement about a pivot point located at the position of the user's knees.
- the shapes and positions of the grooves 24 can be selected so as to achieve such movement.
- the position of the point about which the foot rest 14 pivots can be chosen at will.
- the position of the affective pivotal connection of the back rest 12 to the seat pad 10 can be selected at will so as to be located at approximately the position of the user's hips.
- the design is advantageous in that the provision of a complex, typically metallic, support structure for the various moving components of the chair can be avoided.
- the weight and cost of the furniture can thus be reduced which has obvious benefits.
- the paths of movement followed by the various components can take other forms.
- the grooves could be of part-elliptical form or of a more complex shape.
- the guide means could take the form of guide rails instead of slots or grooves, if desired.
- FIG. 3 illustrates an alternative design of chair.
- the seat pad 10 is not designed to move from a generally horizontal position to an inclined position, but rather is intended to remain in its substantially horizontal configuration in normal use.
- the back rest 12 is secured to the seat pad 10 by an arrangement similar to that illustrated in FIG. 1 but in which three rollers 36 are secured to the back rest 12 , the three rollers 36 being movable within the arcuate groove or slot 34 .
- the foot rest 14 is supported by a telescopic guide arrangement 50 .
- the telescopic guide arrangement 50 comprises an arcuate follower member 52 secured to the foot rest 14 and supported for sliding movement by guide means in the form of three rollers 54 .
- the guide means 54 are supported upon an arcate auxiliary follower member 56 which, in turn, is supported upon guide means in the form of a further set of three roller members 58 carried by the side members 16 .
- the provision of a telescopic guide arrangement 50 is advantageous in that the entire guide arrangement associated with the foot rest 14 can be housed beneath the seat pad. 10 . In the arrangement
- part of the guide arrangement for the foot rest 14 extends above the height of the seat pad 10 and is housed within part of the base component 28 which may result in an increase in the dimensions and complexity of the base component.
- FIG. 3 The arrangement illustrated in FIG. 3 is designed such that when the seat back 12 is moved from its upright configuration to a reclined configuration, the remainder of the chair is moved forwards. Consequently, the furniture can be positioned adjacent a wall and movement of the seat back 12 to a reclined position does not result in the seat back 12 contacting the wall surface as the remainder of the chair moves forward to accommodate such movement.
- the arrangement illustrated in FIG. 3 is designed such that when the seat back 12 is moved from its upright configuration to a reclined configuration, the remainder of the chair is moved forwards. Consequently, the furniture can be positioned adjacent a wall and movement of the seat back 12 to a reclined position does not result in the seat back 12 contacting the wall surface as the remainder of the chair moves forward to accommodate such movement.
- this is achieved by supporting the chair upon a base component 60 by supporting the chair upon rollers, and by using a belt 62 secured to the base component 60 , wrapped around one of the rollers and secured to a lower end of the seat back 12 to drive the chair for movement relative to the base component 60 , movement of the seat back 12 to its reclined position driving the chair forwardly relative to the base 60 .
- FIG. 4 illustrates another design of chair which is very similar to that of FIG. 3 .
- the seat back 12 is supported by a pair of grooves 34 , each of which accommodates a single roller 36 .
- the grooves 34 are concentric about a pivot axis about which the seat back 12 moves, in use.
- liners 60 may be provided (as shown in FIG. 5 ) to assist in the smooth movement of the rollers 22 , 36 .
- the use of liners 60 may increase the range of materials suitable for use in the invention.
- the liners 60 conveniently include shoulders 62 serving to retain the associated rollers within the grooves. It may, further, be possible to avoid using rollers and instead provide slides slidable within the lined grooves.
- the chair 110 comprises an outer frame or support 112 including a pair of side walls.
- An inner frame or support 114 is secured within the outer support 112 for movement relative thereto.
- the mounting of the inner support 114 to the outer support 112 is in the form of rollers 116 carried by the inner support 114 which are received within guide grooves 118 formed in the outer support 112 .
- the inner support 114 is able to move relative to the outer support 112 along a path of movement defined by the shapes and relative orientations of the grooves 118 and, in the arrangement illustrated, the path of movement is an angled translatory movement, the inner support 114 being movable upwards and forwards from one position to another.
- the inner support 114 carries the seat pad of the chair 110 .
- the inner and outer supports 112 , 114 could take a range of forms but, as best shown in FIG. 7 , preferably each include a pair of side walls 1121 114 a , which lie parallel and adjacent one another.
- the chair 110 further comprises a back support 120 which is mounted for movement between an upright position and a reclined position.
- the back support 120 is provided with a series of rollers located within a guide groove formed in the inner support 114 in the manner described hereinbefore, to guide the back support 120 for reclining movement relative to the inner support 114 .
- the back support 120 is further provided with similar rollers 122 received within grooves or slots 124 formed in the outer support 112 , and it will be appreciated that the angle of the back support 120 is dependent upon the position of the inner support 114 relative to the outer support 112 at any given time.
- a foot rest assembly 126 Connected to the inner support 114 is a foot rest assembly 126 of form substantially identical to that described hereinbefore, but including an additional telescopic component and four support bearings, the foot rest assembly 26 being movable between a substantially vertical, rest configuration and a substantially horizontal, in use configuration.
- the chair 110 further comprises a motor 128 of the form including a threaded shaft rotatable by the motor, rotation of the shaft causing a nut component to translate along the length of the shaft.
- the nut component is secured to an output component 130 having a bracket 132 formed thereon to which a drive bar 134 is secured, the drive bar 134 being secured at its opposite end to the foot rest assembly 126 .
- operation of the motor 128 drives the foot rest 126 between its rest and in use configurations.
- the inner support 114 includes an abutment with which the component 130 is engageable at the time at which the foot rest 126 reaches its in use configuration.
- the motor 128 results in the abutment, and hence the inner support 114 being driven from its rearward position to its forward, raised position.
- the movement of the inner support 114 results in the back support 120 being driven from its upright condition to its reclined condition.
- the foot rest 126 is secured to the inner support 114 , it will be appreciated that the movement of the inner support 114 results in similar translatory movement of the foot rest 126 . It will thus be appreciated that a single motor 128 can be used to drive both the foot rest 126 between its rest and in use conditions, and to drive the chair 110 between its upright and reclined configurations.
- the motor 128 In order to return the chair 110 to its upright configuration, the motor 128 is driven in the reverse direction. The weight of the inner support 114 (and the user if seated upon the chair) results in the inner support 114 translating along the angled path defined by the grooves 18 towards its rearward position which, in turn, results in the back support 120 returning to its upright position. Once the inner support 114 has reached its rearward position, further operation of the motor 128 serves to retract the foot rest 126 .
- the chair 110 has a number of advantages. Firstly, a single motor can be used to drive the foot rest 126 and drive the chair 110 between its upright and reclined configurations. Secondly, it will be appreciated that the chair when in its reclined position does not project significantly further rearward than when in its upright condition. Consequently, the chair 110 is of substantially zero wall form. Further, as the foot rest 126 is deployed prior to commencement of reclining movement of the chair 110 , it will be appreciated that the foot rest 126 can be used both with the chair in its upright configuration and with the chair in its reclined configuration.
- the chair could be of manually driven form rather than using a motor.
- a user applying rearward pressure to the back support 120 will drive the back support 120 towards its reclined configuration which, in turn, will drive the inner support 114 from its stowed position to its deployed position.
- Subsequent release of the lock arrangement in combination with the weight of the inner support 114 will result in the chair 110 being returned to its upright configuration if a lesser force is applied to the back support 120 .

- Field of the Invention
- This invention relates to adjustable furniture, for example to chairs or beds or the like in which the position of one weight or load carrying part of the furniture can be moved relative to another. The adjustment may be motorized or alternatively may be achieved manually.
- Description of the Related Art
- Adjustable chairs are well known in which the angle of the seat back can be changed in order to provide a recline position and/or in which a movable foot rest is provided. Chairs of this type are available in which adjustment is achieved manually or in a motorized fashion. Some motorized chairs have the ability to incline the seat of the chair to assist the user in moving from a seated position to a standing position. Adjustable beds are also known in which a head and upper back supporting region of the bed can be moved to adjust the inclination thereof.
- Typically, the movable parts of such items of furniture are supported upon relatively complex, typically steel, support arrangements, often including a series of linkages movable to allow the movable part of the piece of furniture to travel through its desired range of movement. Such support arrangements are often costly and heavy, making transportation, handling and use awkward, and place severe restrictions on the designs of furniture which are available.
- It is an object of the invention to provide an arrangement in which the disadvantages set out above are reduced
- According to one aspect of the present invention, there is provided an adjustable furniture comprising a first furniture component, a second furniture component movable, in use relative to the first furniture component and supported by a guide arrangement comprising a guide associated with one of the first and second components and at least one follower associated with the other of the first and second components and movable along the guide.
- According to the present invention there is provided adjustable furniture comprising a first furniture component, a second furniture component movable, in use, relative, to the first furniture component and supported by a guide arrangement comprising a guide associated with one of the first and second components and at least one follower associated with the other of the first and second components and movable along the guide.
- Preferably at least two followers are provided, the followers being in a fixed relationship to one another. The guide conveniently comprises an elongate slot or groove in which the follower(s) are located. The follower(s) conveniently comprise rollers. The guide could, alternatively, comprise a guide rail or the like secured to the said one of the first and second components.
- The guide, for example in the form of an elongate slot, or groove, may be of arcuate form, having a fixed radius of curvature, to guide the first and second components for relative pivoting-like movement about a pivot axis located at the centre of curvature of the guide. Alternatively, the guide may be of, for example, part elliptical form or be of a more complex shape.
- Where the furniture is a chair, the first and second components may comprise one or more of the base of the chair, the seat pad, the seat back, the foot rest or other supporting part of the chair. Where the furniture is a bed, the components may comprise parts thereof which are relatively movable and which, in use, are adapted to bear at least part of the weight of the user of the furniture.
- According to another aspect of the invention there is provided an article of furniture comprising an outer support, and inner support guided for movement relative to the outer support, and back support guided for movement relative to both the inner support and the outer support.
- The inner, outer and back supports may be guided for movement using any of the arrangements described hereinbefore.
- In such an arrangement, the inner support may comprise, for example, a seat pad support. The arrangement is such that the seat pad support and back support move simultaneously between an upright configuration and a reclined configuration. In the reclined configuration, the back support does not project significantly further rearward of the furniture than when in its upright configuration. The furniture is thus of “zero-wall” form.
- The furniture may be manually driven between its upright and reclined configurations, or alternatively may be motorized.
- A footrest, for example of the type described hereinbefore, may be provided, the footrest being movably mounted to the inner support. It may be manually movable or alternatively may be motorized. Preferably a single motor is used to drive the furniture between its upright and reclined configurations and to drive the footrest. For example, from an upright configuration, an initial part of the motor operation may drive the footrest, a final part of the operation driving the furniture to its reclined configuration

- The chair illustrated in
FIGS. 1 and 2 is an adjustable chair of the motorized form and comprises a number of relatively movable chair components. Specifically, the chair comprises aseat pad component 10 which is angularly movable between a position in which it lies generally horizontally (as shown), and a tilted or inclined position in which it is raised to assist a user in moving from a seated position to a standing position. The chair further comprises an adjustableback rest component 12 and an adjustablefoot rest component 14. - In the arrangement illustrated in
FIG. 1 , theseat pad 10 comprises a pair ofside support members 16 between which is secured a seatpad support member 18, the upper surface of which carries a suitably padded and upholsteredcushion 20. Thesupport members 16 each carry two pairs ofrollers 22 which, in use, are able to ride withinarcuate guide grooves 24 provided inside members 26 of abase component 28. - The
base component 28 andseat pad 10 include respectivemotor mounting brackets brackets seat pad 10 occupies substantially the position illustrated to an extended condition, then theseat pad 10 will be moved, therollers 22 acting as followers, being guided for movement within the respectivearcuate grooves 24 to cause theseat pad 10 to move from the generally horizontal position illustrated to an inclined position, theseat pad 10 moving through a pivot-like motion about a pivot point defined by the centre of curvature of the twoarcuate grooves 24. - As illustrated, the
side members 16 are each provided with anarcuate groove 34 within which a pair ofrollers 36 carried by abracket 38 can move, thebracket 38 serving to support the seat back 12. It will be appreciated, therefore, that theseat back 12 is guided for pivot-like movement relative to theseat pad 10 about a pivot point located at the centre of curvature of thearcuate groove 34. Thebracket 38 andside members 16 are provided with mountingbrackets 40 between which an actuator is connected and, as with theseat pad 10, adjustment of the length of the actuator causes therollers 36 to move within thearcuate groove 34 to adjust the angle of inclination of the seat back 12. - The
foot rest 14 is mounted upon abracket 42 having a pair ofrollers 44 secured thereto, therollers 44 being located within anarcuate groove 46 formed in theside member 26 of thebase component 28. Thebracket 42 further serves as a mounting bracket for a motor device, the other end of which is secured to a mountingbracket 48 associated with thebase component 28 to drive thefoot rest 42 between a substantially vertical orientation as illustrated inFIGS. 1 and 2 and a substantially horizontal configuration. - It will be appreciated that from the position illustrated in
FIG. 1 , if desired a user can operate the motors of the chair to cause thefoot rest 14 to be driven from the position illustrated towards a substantially horizontal configuration, therollers 44 riding within theguide groove 46 to support and guide thefoot rest 14 through such movement. The back rest can be adjusted between the substantially vertical position illustrated and a reclined position by operation of the appropriate motor to cause therollers 36 to ride along the length of thearcuate groove 34, therollers 36 andgroove 34 serving to guide and support theback rest 12 through such movement. The movement of thefoot rest 14 may be controlled independently of the movement of theback rest 12, if desired. - Further, from the position illustrated in
FIG. 1 theseat pad 10 may be moved to an inclined position, therollers 22 moving within thearcuate grooves 24 to guide and support theseat pad 10 through such movement, the movement of theseat pad 10 serving to assist a user in moving from a seated position towards a standing position. During the movement of the seat pad, if desired, the position of the seat back 12 relative to theseat pad 10 may also be adjusted so as to ensure that the position of the seat back 12 does not interfere with the movement of the user towards a standing position. - It will be appreciated that as the paths of movement of the various components of the chair are determined by the shape and position of the
grooves seat pad 10 to follow a pivot-like course of movement about a pivot point located at the position of the user's knees. As the user's knees project, in use, in front of the chair, such design is not usually possible. However, with the furniture of the present invention, the shapes and positions of thegrooves 24 can be selected so as to achieve such movement. Likewise, the position of the point about which thefoot rest 14 pivots can be chosen at will. Similarly, the position of the affective pivotal connection of theback rest 12 to theseat pad 10 can be selected at will so as to be located at approximately the position of the user's hips. - The design is advantageous in that the provision of a complex, typically metallic, support structure for the various moving components of the chair can be avoided. The weight and cost of the furniture can thus be reduced which has obvious benefits. Although in the arrangement described hereinbefore the various components
- are arranged to undertake relative pivot-like movement, it will be appreciated that by appropriate selection of the shapes and positions of the
grooves -
FIG. 3 illustrates an alternative design of chair. In the design illustrated inFIG. 3 , theseat pad 10 is not designed to move from a generally horizontal position to an inclined position, but rather is intended to remain in its substantially horizontal configuration in normal use. Theback rest 12 is secured to theseat pad 10 by an arrangement similar to that illustrated inFIG. 1 but in which threerollers 36 are secured to theback rest 12, the threerollers 36 being movable within the arcuate groove orslot 34. - The
foot rest 14 is supported by atelescopic guide arrangement 50. Thetelescopic guide arrangement 50 comprises anarcuate follower member 52 secured to thefoot rest 14 and supported for sliding movement by guide means in the form of threerollers 54. The guide means 54, in turn, are supported upon an arcateauxiliary follower member 56 which, in turn, is supported upon guide means in the form of a further set of threeroller members 58 carried by theside members 16. The provision of atelescopic guide arrangement 50 is advantageous in that the entire guide arrangement associated with thefoot rest 14 can be housed beneath the seat pad. 10. In the arrangement - Illustrated in
FIG. 1 , it will be appreciated that part of the guide arrangement for thefoot rest 14 extends above the height of theseat pad 10 and is housed within part of thebase component 28 which may result in an increase in the dimensions and complexity of the base component. - The arrangement illustrated in
FIG. 3 is designed such that when the seat back 12 is moved from its upright configuration to a reclined configuration, the remainder of the chair is moved forwards. Consequently, the furniture can be positioned adjacent a wall and movement of the seat back 12 to a reclined position does not result in the seat back 12 contacting the wall surface as the remainder of the chair moves forward to accommodate such movement. In the arrangement illustrated inFIG. 3 , this is achieved by supporting the chair upon abase component 60 by supporting the chair upon rollers, and by using abelt 62 secured to thebase component 60, wrapped around one of the rollers and secured to a lower end of the seat back 12 to drive the chair for movement relative to thebase component 60, movement of the seat back 12 to its reclined position driving the chair forwardly relative to thebase 60. -
FIG. 4 illustrates another design of chair which is very similar to that ofFIG. 3 . In the arrangement illustrated inFIG. 4 , the seat back 12 is supported by a pair ofgrooves 34, each of which accommodates asingle roller 36. Thegrooves 34 are concentric about a pivot axis about which the seat back 12 moves, in use. - Although in the arrangements described hereinbefore the
rollers liners 60 may be provided (as shown inFIG. 5 ) to assist in the smooth movement of therollers liners 60 may increase the range of materials suitable for use in the invention. Theliners 60 conveniently includeshoulders 62 serving to retain the associated rollers within the grooves. It may, further, be possible to avoid using rollers and instead provide slides slidable within the lined grooves. - Referring to
FIG. 6 there is illustrated an article of furniture in the form of anarmchair 110. Although the article of furniture in this case is anarmchair 110, it will be appreciated that the invention described herein is equally applicable to other forms of furniture, for example to sofas or to beds. Thechair 110 comprises an outer frame orsupport 112 including a pair of side walls. An inner frame orsupport 114 is secured within theouter support 112 for movement relative thereto. The mounting of theinner support 114 to theouter support 112 is in the form ofrollers 116 carried by theinner support 114 which are received withinguide grooves 118 formed in theouter support 112. It will be appreciated that theinner support 114 is able to move relative to theouter support 112 along a path of movement defined by the shapes and relative orientations of thegrooves 118 and, in the arrangement illustrated, the path of movement is an angled translatory movement, theinner support 114 being movable upwards and forwards from one position to another. - The
inner support 114 carries the seat pad of thechair 110. - The inner and
outer supports FIG. 7 , preferably each include a pair of side walls 1121 114 a, which lie parallel and adjacent one another. - The
chair 110 further comprises aback support 120 which is mounted for movement between an upright position and a reclined position. Theback support 120 is provided with a series of rollers located within a guide groove formed in theinner support 114 in the manner described hereinbefore, to guide theback support 120 for reclining movement relative to theinner support 114. Theback support 120 is further provided withsimilar rollers 122 received within grooves orslots 124 formed in theouter support 112, and it will be appreciated that the angle of theback support 120 is dependent upon the position of theinner support 114 relative to theouter support 112 at any given time. - Connected to the
inner support 114 is afoot rest assembly 126 of form substantially identical to that described hereinbefore, but including an additional telescopic component and four support bearings, thefoot rest assembly 26 being movable between a substantially vertical, rest configuration and a substantially horizontal, in use configuration. - The
chair 110 further comprises amotor 128 of the form including a threaded shaft rotatable by the motor, rotation of the shaft causing a nut component to translate along the length of the shaft. The nut component is secured to anoutput component 130 having abracket 132 formed thereon to which adrive bar 134 is secured, thedrive bar 134 being secured at its opposite end to thefoot rest assembly 126. In use, operation of themotor 128 drives thefoot rest 126 between its rest and in use configurations. - As illustrated in
FIG. 6 , theinner support 114 includes an abutment with which thecomponent 130 is engageable at the time at which thefoot rest 126 reaches its in use configuration. Once thecomponent 130 has moved into engagement with the abutment, further operation of themotor 128 results in the abutment, and hence theinner support 114 being driven from its rearward position to its forward, raised position. As described hereinbefore, such movement of theinner support 114 results in theback support 120 being driven from its upright condition to its reclined condition. Further, as thefoot rest 126 is secured to theinner support 114, it will be appreciated that the movement of theinner support 114 results in similar translatory movement of thefoot rest 126. It will thus be appreciated that asingle motor 128 can be used to drive both thefoot rest 126 between its rest and in use conditions, and to drive thechair 110 between its upright and reclined configurations. - In order to return the
chair 110 to its upright configuration, themotor 128 is driven in the reverse direction. The weight of the inner support 114 (and the user if seated upon the chair) results in theinner support 114 translating along the angled path defined by thegrooves 18 towards its rearward position which, in turn, results in theback support 120 returning to its upright position. Once theinner support 114 has reached its rearward position, further operation of themotor 128 serves to retract thefoot rest 126. - It will be appreciated that the
chair 110 has a number of advantages. Firstly, a single motor can be used to drive thefoot rest 126 and drive thechair 110 between its upright and reclined configurations. Secondly, it will be appreciated that the chair when in its reclined position does not project significantly further rearward than when in its upright condition. Consequently, thechair 110 is of substantially zero wall form. Further, as thefoot rest 126 is deployed prior to commencement of reclining movement of thechair 110, it will be appreciated that thefoot rest 126 can be used both with the chair in its upright configuration and with the chair in its reclined configuration. - A number of modifications and alterations may be made to the chair as described hereinbefore. For example, if desired, the chair could be of manually driven form rather than using a motor. In such an arrangement, upon a lock arrangement being released, a user applying rearward pressure to the
back support 120 will drive theback support 120 towards its reclined configuration which, in turn, will drive theinner support 114 from its stowed position to its deployed position. Subsequent release of the lock arrangement in combination with the weight of theinner support 114 will result in thechair 110 being returned to its upright configuration if a lesser force is applied to theback support 120. - In such a manual configuration, the
foot rest 126 is conveniently provided with a resilient biasing means, for example a as strut, operable to drive thefoot rest 126 towards its horizontal configuration, a load applied to thefoot rest 126 by a user returning thefoot rest 126 to its substantially vertical configuration. - Where the chair is a so-called wing over arm chair, then the chair may be designed such that, in use, the
inner support 112 remains stationary in use, theouter support 114 moving as the chair reclines so that the arm of the chair also moves. - Although the description hereinbefore is of adjustable furniture in the form of adjustable chairs, it will be appreciated that the invention is applicable to other forms of adjustable furniture in which load bearing or weight bearing components thereof are adjustable relative to one another. Further, although the chair designs illustrated in
FIGS. 3 and 4 are intended to be manually adjustable or manually driven between their various configurations, it will be appreciated that if desired, the chairs could be automated, appropriate motors being provided to drive the various components of the chairs between the various positions. A number of other modifications and alterations may be made to the arrangements described hereinbefore without departing from the scope of the invention. - Having described at least one of the preferred embodiments of the present invention with reference to the accompanying drawings, it will be apparent to those skills that the invention is not limited to those precise embodiments, and that various modifications and variations can be made in the presently disclosed system without departing from the scope or spirit of the invention. Thus, it is intended that the present disclosure cover modifications and variations of this disclosure provided they come within the scope of the appended claims and their equivalents.
