Abstract
A bath lift (10), the lift (10) comprising a housing (12) locatable to a first side (18) of a bath (20). A flexible band (72) is provided which is selectively extendable from the housing (12) across the bath (20) to a second side (86) of the bath (20) such that a person can sit on the band (72). The lift (10) comprises means for selectively feeding the band (72) out or in of the housing (12) such that when the band (72) is fed out a person sitting thereon is lowered into a sitting position to the bottom of the bath (20), and when the band (72) is fed in, a person sitting thereon is raised off the bottom of the bath (20). The lift (10) is arranged to be selectively movable between an in use position with the band (72) extending from the housing (12) across the bath (20), and an out of use condition with the band (72) located at least substantially within the housing (12). The housing (12) lies in a generally flat configuration to the first side (18) of the bath (20).
Description




This invention concerns bath lifts; and particularly but not exclusively bath lifts for lowering a person in a seated position from substantially level with the top of a bath to sit on the bottom of the bath, and to subsequently raise the person back off the bottom of the bath.




A number of bath lifts are presently available. Such lifts tend to be visually relatively obtrusive even when not in use. Accordingly, such lifts can be visually unappealing. Also, it is sometimes preferred for a bath lift not to be obviously recognisable as such, at least when not in use.




According to the present invention there is provided a bath lift, the lift comprising a housing locatable to a first side of a bath, a flexible band which is selectively extendable from the housing across the bath to a second side of the bath such that a person can sit on the band, the lift comprising means for selectively feeding the band out or in of the housing such that when the band is fed out a person sitting thereon is lowered into a sitting position to the bottom of the bath, and when the band is fed in, a person sitting thereon is raised off the bottom of the bath, the lift being arranged to be selectively movable between an in use position with the band extending from the housing across the bath, and an out of use condition with the band located at least substantially within the housing, the housing lying in a generally flat configuration to said first side of the bath.




The bath lift is preferably arranged such that the housing lies in a generally vertical plane, and desirably can be mounted to lie against a wall or fixture.




The bath lift is preferably arranged such that a free end of the band is selectively mountable on said second side of the bath, and a first guide is provided in or adjacent a lower part of a housing such that, from said free end, the band extends across the bath, a second movable guide being provided in the housing above the first guide, with the band extending around the second guide to a fixed end below the second guide, means being provided for moving the second guide relative to the first guide so as to feed the band past the first guide and therefore into or out of the housing to selectively tighten or loosen the band extending across the bath, to raise or lower a person sitting on the band.




The second guide is preferably movable in a generally vertical direction. The second guide may extend between generally vertically aligned guide paths.




The moving means may comprise a rotatable threaded elongate member extending substantially vertically, and engagable with a threaded member connected to the second guide such that rotation of the threaded elongate member causes the second guide to rise or fall.




The guide paths may comprise tracks, and the second guide may extend between two carriages each located in a respective one of the tracks. The tracks may comprise lengths of channel section open sidewards to face each other.




A motor may be provided to rotate the threaded elongate member, and the motor may be located above the threaded elongate member.




Control means may be provided for the motor operable by a person sitting on the band. The control means may comprise an elongate member with limited vertical movement, the elongate member in a relaxed condition adopting a neutral position but being movable upwardly or downwardly, with upward movement connecting the motor for rotation in one direction, and downward movement of the elongate member connecting the motor for rotation in the other direction. An engagement member is preferably provided on the elongate member engagable respectively with one of two switches when the elongate member is urged from a relaxed condition. The elongate member preferably extends substantially vertically.




The positioning of the band on the fixed end may be adjustable. The fixed end may comprise a member around which the band extends in a closed loop. The fixed end member may be selectively removable from the housing. The positioning of the closed loop may be adjustable, and a fastener such as a fleece and hook fastener may be provided on the end of the band to permit a loop to be formed around the fixed end member. With the fixed end member removed from the housing a required amount of band may be wound therearound to provide a required position of the closed loop along the band.




The housing may comprise a main body locatable against a wall or fixture, and containing at least the fixed end member, the second guide and the threaded elongate member. The housing may also comprise a door which when closed covers at least a substantial part of the band which is located in the main body. The door may comprise on an inner side, engagement means for accepting the free end of the band when in the out of use condition such that substantially all of the band in said condition is located within the housing. The engagement means may comprise a bar over which the band can lie in a loop, and the bar may be pivotally mounted on the inside of the door. A mirror or other decorative arrangement may be provided on the outside of the door.




The bath lift may comprise holding means mountable on any of the second side of the bath, on the floor adjacent thereto, or a similar location, to releasably hold the free end of the band. The holding means may be arranged to automatically hold the free end of the band upon the free end being presented thereinto.




A fixing member may be provided on the free end of the band, and the fixing member may comprise a bar extending across the free end of the band and held within a closed loop of band. The fixing member may also comprise a profiled member mounted on the bar, and the profiled member may comprise an engagement formation and/or a handle formation.




The holding means may comprise a member presenting an opening into which the fixing member, and desirably the engagement formation thereof, is locatable. Resilient means may be provided for retaining the fixing member in the opening.




Lock means may be provided for locking the housing closed. The lift may be arranged to be coin operable, or only operable when a specific key is inserted therein.

The drawings show a bath lift


10


comprising a substantially flat housing


12


. The housing


12


comprises an open rectangular frame


14


of a small depth which is mounted on the wall


16


adjacent a first side


18


of a bath


20


. A door


22


is provided for the housing


12


, which is hinged along one side of the frame


14


and extends across almost the whole width of the frame


14


. A cover


24


covers the narrow strip along the side of the frame


14


which is not closed by the door


22


.




The sides


26


of the frame


14


are in the form of inwardly facing channel section which define tracks. A bar


28


extends across the frame


14


towards the lower end thereof. The bar


28


is removably mounted against the frame


14


by bolts


30


. A carriage


32


slidably extends in each of the tracks


26


, and each of the carriages


32


comprise a pair of spaced rollers


34


engagable in the tracks with the rollers


34


mounted about horizontal axes. A further roller (not shown) may be provided at the lower end of each carriage


32


extendable about a vertical axis. An upper and a lower bar


36


,


38


extend between the respective carriages


32


, and strengthening webs


40


extend between each carriage


32


and the lower bar


38


. A threaded socket


42


is provided in the upper end of the left hand carriage


32


as shown in the drawings. The socket


42


has a threaded through hole with a vertical axis.




A threaded elongate member


40


is provided extending adjacent the left hand track


26


as shown in the drawings, and engagingly extending through the socket


42


. The member


44


is rotatably mounted within the frame


14


and extends into a housing


46


thereabove. An electric motor


48


is located within the housing


46


and connected to the member


44


to cause rotation thereof in either direction.




A control arrangement


50


is provided for the motor


48


. The arrangement


50


comprises an elongate member


52


located parallel to the member


44


but outside of the housing


12


. The member


52


is located at its lower end on an upstanding pin


54


which extends within the member


52


. At the upper end of the member


52


a further housing


56


located immediately below the housing


46


, and the upper end of the member


52


extends into the housing


56


.




An engagement collar


58


is provided on the upper end of the member


52


. A spring


60


is provided around the member


52


extending between the collar


58


and a lower surface of the housing


56


. The spring


60


urges the member


52


into a neutral position as shown in FIG.


5


. The collar


58


comprises a finger


62


which in the neutral position locates without contact between two micro switches


64


. When the member


52


is pulled downwardly the finger


62


actuates a lower of the switches


64


to cause the motor


48


to rotate in a first direction such that the carriages


32


move downwardly. If the member


52


is pushed upwardly this will actuate the upper switch


64


to cause the motor


48


to rotate in the opposite direction and hence the carriages


32


to move upwardly.




A guide bar


66


extends between two projections


68


projecting downwardly from the frame


14


. A support bar


70


(

FIG. 2

) is pivotally mounted about one end to the inside of the door


22


about a third of the way up the door


22


, such that the bar


70


can lie flat against the inside of the door


22


or pivot outwardly therefrom.




The lift


10


comprises a flexible band


72


located as follows. A closed loop is provided in an end of the band


72


around the bar


28


. A fastener such as fleece and hook fastener is provided on the band


72


to permit the loop to be formed, and the band is then rolled around the bar


28


, with the bar


28


removed from the frame


14


, to provide a required total length of band


72


. From the bar


22


the band extends upwardly within the frame


14


over the inner side of the upper bar


36


to extend downwardly still within the frame


14


to the inner side of the guide bar


66


.




In an out of use condition as shown in

FIG. 2

the free end


74


of the band


72


is looped over the support bar


70


such that substantially all of the band


72


can lie within the housing


12


and be contained therewithin if the door


22


is shut as shown in FIG.


1


.




In an in use condition the band


72


is taken off the support bar


70


and extends across the bath


20


. A bar


76


is mounted across the free end


74


and held therein by a stitched closed loop. A profiled member


78


is mounted on the bar


76


. The member


78


comprises a first part shaped to define a lip


80


, and a second part extending on the opposite side of the member


78


to provide a tab


82


.




A holding arrangement


84


is provided. The arrangement


84


can be mounted on the second side


86


of the bath just below the top thereof as shown in the drawings. Alternatively the arrangement


84


can be mounted lower down on the bath, on the floor adjacent the bath, or elsewhere. The arrangement


84


comprises a profiled strip which has a lower section


88


to define a mounting flange to enable mounting thereof on a bath


20


or otherwise. Extending above the section


88


is an outwardly facing channel section


90


with a downwardly pointing lip


92


on the top wall


94


of the channel. A recess


96


with a narrowed opening is provided along the lower insider corner of the channel. Pivotally located within the recess


96


is the circular section end of a retaining strip


98


. A length of resilient material


100


such as foamed plastics material is provided beneath the strip


98


to urge the strip upwardly to at least substantially close the channel. A projection


102


is provided running along the bottom wall


104


of the channel to retain the resilient material


100


in place.




To use the lift


10


, the free end


74


is taken out of the housing


12


as outlined above. The end


74


is then located in the holding arrangement


84


by pushing the lip


80


into the channel of the section


90


to be retained therein by the strip


98


. The band


72


will then be extending across the top of the bath


20


as shown in FIG.


3


. If the band


72


is not taut it can be tightened by pushing the member


32


upwards to activate the motor


48


to move the carriages


32


upwards and hence lengthen the portion of the bands


72


located within the housing


12


. When the band


72


is taut a person can sit thereon. To lower themselves into the bath


20


, the person pulls the member


52


downwardly to actuate the motor


48


in a required direction to feed the band


72


out of the housing


12


until the band


72


reaches the bottom of the bath


20


. Following bathing a person can be lifted back up to the top of the bath


20


by pushing the member


32


upwardly such that the band


72


is fed back into the housing


12


.




There is thus described a bath lift with a number of advantageous features. The lift allows a person to be lowered and raised to and from the bottom of a bath in a conventional manner using a control arrangement which is extremely easy to operate. The lift only projects out a short distance from the wall and when not in use provides a very neat and unobtrusive arrangement. The front of the door


22


can be in the form of a mirror as shown in the drawings or can be decorated in many different ways. The door could be provided with a panel which could be decorated to correspond to the decoration surrounding the bath. For use in commercial establishments a lock could be provided on the door


22


as shown by the lock


106


in FIG.


1


. Alternatively, a coin or key operated mechanism could be provided.




Various other modifications may be made without departing from the scope of the invention. For example, a different method could be provided for moving the carriages within the housing. A different method could be provided for mounting the free end of the band on the second side of the bath, though the present arrangement has been found to be particularly advantageous.




Whilst endeavouring in the foregoing specification to draw attention to those features of the invention believed to be of particular importance it should be understood that the Applicant claims protection in respect of any patentable feature or combination of features hereinbefore referred to and/or shown in the drawings whether or not particular emphasis has been placed thereon.
