- Figure 10 is a schematic longitudinal cross- section of a socket adapted to receive the probe of the plug of. Figure 9. . . .
- a bath 1 for use by a physically handicapped or physically impaired person comprises a bath tub 2 provided with a peripheral rim 3 and apparatus 4 for assisting the person into and out of the bath tub 2.
- the apparatus 4 comprises a vertically-disposed telescopic column 5 having a stationary outer or cylinder part 6 disposed a little beneath the rim 4 and an inner or ram part 7 movable relative to the outer part 6, within an aperture 8 formed in the rim 3.
- the apparatus 4 comprises a seat unit 15 demountably connectable to the movable inner part 7 of the telescopic column 5, and formed by a seat 16 and a seat support arm 17, one end of which is demountably connectable to the movable inner part 7.
- the arrangement is such that, with the seat unit 15 disconnected from the movable inner part 7, the inner part can be retracted to an unobtrusive position, substantially at the level of the rim 3.
- the words “substantially at the level of the rim” include a position slightly (say 20.00mm to 80.00mm) below said level.
- the aperture 8 can be closed by a cap 20, so as to cover the retracted inner part 7.
- the seat support arm 17 extends, in a cantilever ⁇ like manner, from a base 21, into apertures 22 formed in the sides of the back rest of the seat 16.
- the upper end of the inner part 7 is formed with a central recess 23 of circular cross-section which locates, with small side clearance, a central, co-operating, spigot 24 projecting downwardly from the base 21.
- the load imposed on the seat 16 by the weight of a person carried thereby is transferred to the inner part 7 by way of the arm 17, and the spigot 24 of the base 21.
- the length of the spigot 24 is such that the weight load imposed cannot result in the spigot being tipped out of the recess 23.
- the arrangement also allows the base 21 and thus the arm 17, to swivel about the inner part 7.
- the seat 16 and arm 17 are readily removed from the inner part 7.--All that needs to be done is to lift the arm, with its rronnected base 21, from the inner part 7.
- the cap 20 is formed with central, downward extending, spigot 25 whereby the cap 20 is held in place by location of the spigot by the recess 23.
- the cap 20 and/or aperture 8 may be formed so that the cap is held in place more securely.
- the cap may be made to engage with the aperture 8 by way of a bayonet connection.
- the bath tub 2 has one side portion of lesser height than the opposite side portion thereof. This is to assist entry to and exit from the bath tub.
- Figure 1 also shows a mixer bath tap 30, hanc* grips 31, adjustable tub supports 32, a waste outlet 33, an overflow duct 34, and a load reaction base 35 for the column 5. Also evident is that the telescopic column 5 is .-.sposed laterally of the central longitudinal axis 36 of the bath tub 2. The arrangement enables the seat 16 to be raised from a lowered, (in bath tub) position, to an elevated position, and then to swivel the seat to a position in which it extends over the rim 3. Also, to swivel the seat 16 in the opposite direction and then lower it into the bath tub 2.
- FIG 4 illustrates an alternative seat support arm comprising a vertical shaft 60 to which a horizontal seat support shaft 61 is mounted at a point somewhat below the top end 62 of the vertical shaft 60.
- Support shaft 61 extends into an aperture formed in the side of the back rest of the seat 16.
- a handle 63 is provided for swivelling the seat 16 about the vertical shaft 60 to allow a user to mount the seat 16 outside the bath tub 2.
- the vertical shaft 60 has a base 65 having a spigot (not shown) which is received by the upper end of the inner part 7 of the telescopic column 5.
- the seat 16 and seat support arm 60, 61 are readily removed from the inner part 7 of the telescopic column 5 by lifting the arm 60, 61 and associated base 65 from the inner part 7.
- the inner part 7 can then be retracted to its unobtrusive position and the aperture in the bath tub rim closed by a closure member (not shown).
- the telescopic column 5 is directly operable by hydraulic fluid by way of combined flow and return ducts 40, 41, connected to a pump 42 driven by an electric motor 43.
- the pump and motor together form a hydraulic power unit 44, which is controlled manually by a remote switch 45, electrical power being provided by a cable 46.
- the inner part 7 of the telescopic column 5 is powered in both up and down directions, and does not rely on the weight of a person carried by the seat 16, or action by another, such as a nurse, pressing downwardly on the seat, in order to retract the inner part. Thus accidental trapping of fingers by retraction of the inner part 7 is avoided as far as possible.
- FIG 6 illustrates how the hydraulic operating mechanism shown diagrammatically in Figure 5 can be arranged in the bath shown in Figure 4.
- an electro-hydraulic power pack comprising the pump 42, and power unit 44 are mounted on a removable steel chassis (now shown).
- a valve block 70 (not shown in figure 5) is provided from which the flow and return ducts 40, 41 extend to the telescopic column 5.
- the power pack also has an oil reservoir 71 (not shown in Figure 5).
- the power pack is electrically powered by suitable circuitry (not shown).
- This electrical circuitry may be pneumatically controlled by a pneumatic control means (not shown) operated by a removable manual actuator (not shown).
- the pneumatic control means may include a pressure sensitive switch housed in the bath and adapted to operate the power pack.
- the manual actuator may be connected to the pressure sensitive switch by pneumatic lines via a plug and socket which permit the manual actuator and associated pneumatic lines to be removed when the bath is not in use.
- the socket is shown in the bath illustrated in Figure 6 and is identified by the numeral 210.
- the present invention enables both a handicapped and a non-handicapped person to use the same bath. Assuming the handicapped person to use the bath 1 first, the seat unit 15 is then removed, the inner part 7 of the telescopic column 5 retracted, and the cap 20 placed in position. With the seat unit 15 stowed out of sight, there is nothing to indicate that earlier the dual purpose bath 2 had functioned in another mode.
- the telescopic column 15 may be replaced by one which has a movable outer part and a stationary inner part.
- the invention has particular application to hotels and like accommodation where the bath can readily be converted from one mode to another.
- Figure 7 illustrates a modification wherein the hydraulic fluid is pressurised indirectly by water- powered means comprising a water-pressure intensifier 50.
- Water at mains supply pressure enters and leaves the intensifier 50 by way of flow and return pipes 51, 52 respectively.
- the intensifier 50 operates so that a relatively low water mains pressure is used to apply a relatively large force to the hydraulic fluid.
- a suitable intensifier is illustrated in Figure 8.
- a hydraulic actuator 101 in the form of a telescopic column is used to lift and lower the seat within the bath tub (not shown), enabling a physically handicapped person to use the tub.
- the actuator 101 comprises an outer stationary part 102 and an inner movable part 103.
- the actuator 101 is operable by a hydraulic pressure intensifier 110 comprising a relatively large area piston 111 movable within a first cylinder 112, and a relatively small area piston 113 movable within a second cylinder 114.
- the first and second cylinders 112, 114 are in substantially co-axial alignment, one behind the other, in tandem relationship, with a common longitudinal axis 115.
- a piston rod 116 interconnects the two pistons 111, 113.
- a piston rod seal 117 prevents direct flow of fluid between the cylinders 112, 114.
- Inle /outlet ducts 120, 121 comprise reversible inlet and outlet means which allow hydraulic fluid to be admitted to the first cylinder 112 and hydraulic fluid to escape therefrom.
- inlet/outlet ducts 122, 123 comprise reversible inlet and outlet means which allow hydraulic fluid to be admitted to the second cylinder 114 and hydraulic fluid to escape therefrom.
- the ends of the ducts 120, 121 remote from the cylinder 112 are connected to a two-way control valve 125 operable by a lever 126.
- the valve 125 has a water inlet 127 connected to the mains supply and a water outlet 128 discharging the waste.
- the valve 125 is operable so that the inlet 127 can be connected either to the duct 120, as shown, or to the duct 121.
- the duct 121 can be connected either to the outlet 128, as shown, or to the inlet 127.
- the cylinder 114 and ducts 122, 123 connected thereto, plus the interior 130 of the actuator outer part 102, are filled with hydraulic oil.
- the inner part 103 of the actuator 101 is of stepped section, the smaller diameter portion thereof being sealed to the outer part 102 by a seal 131.
- valve 126 In operation, to lift the inner part 103 of the actuator 101, the valve 126 is positioned as shown, so that water at a relatively low pressure is admitted to the first cylinder 112 so that it acts on the piston 111, displacing it to the right, as indicated by arrow 135. At the same time, water is displaced from the back of the piston 111, and flows to waste, by way of the drain 128.
- Displacement of the piston 111 causes corresponding displacement of the piston 113 whereby hydraulic oil, at higher pressure than that of the water acting on piston 111, (because of the difference in piston areas), is caused by piston 113 to enter the hydraulic interior 130 and move the inner part 103 of the actuator upwardly. Any oil trapped in the space 130 returns to the cylinder 114 by way of duct 122.
- the actuator 101 could be replaced by one having an inner stationary part and an outer movable part.
- a plug and socket connector in accordance with the fourth aspect of the present invention which is suitable for use in a pneumatic control system for operating a bath hoist (such as that illustrated in Figures 1 and 4) is shown in Figures 9 and 10.
- a pneumatic plug 200 of a plug and socket connector comprises a single probe portion 201 and a handgrip portion 202.
- the probe portion 201 is provided with two axially spaced-apart radial ports 203 which are independently connected internally of the plug 200 to respective supply passages 204 which terminate in nipples 205 at the outer end of the probe 201 for connection to respective pneumatic lines 206.
- the handgrip portion 202 includes a recess 207 in which the outer end of the probe portion 201 is mounted. At the junction of the probe portion 201 and the handgrip portion 202 the parts may be threaded to facilitate secure connection.
- a socket element 210 of the plug and socket connector is shown.
- the socket 210 has a bore 211 adapted to receive the probe portion 201 of the plug 200.
- the probe 201 and the socket bore 211 are of complementary plain cylindrical shape.
- the probe portion 201 of the plug 200 is provided with three annular spaced-apart sealing means 215 which are arranged such that when the plug 200 and socket 210 are fully inter-engaged, each of the radial ports 203 is positioned axially between a respective pair of the annular sealing means 215.
- the socket 210 is provided with respective passages 216 communicating respectively with the chambers defined between the respective pairs of annular sealing means 215.
- the passages 216 terminate in connecting nipples 217.
- the outer end of the probe 201 is arranged to connect with a pneumatic conduit 220 in which the pneumatic lines 206 are contained within an outer sheath 221.
- the connection between the outer end of the probe 201 and the pneumatic lines 206 is housed within the recess 207 of the handgrip portion 202 of the plug 200.
- the illustrated socket 210 is suitable for mounting on a bath, for example on a side panel of the bath.
- the connecting nipples 217 of the socket 210 can be connected to a pressure-sensitive switch or control mechanism associated with a hoist actuator, which may be concealed in a housing associated with the bath tub or remote therefrom.
- the plug 200 may be connected to a removable hand control (not shown) comprising a push button/bellows/valve unit adapted to be mounted on or adjacent to the bath tub when a detachable hoist is mounted in position. It will be appreciated that the plug 200 could be lengthened to accommodate more than two air passages for controlling more than two supply lines.
