Abstract
Wheelchair apparatus which is manually separable into four main units namely a lifting device, a seat unit, a wheeled chassis and a portable battery/compressor unit, of which the device and unit can be employed as static lifting apparatus, e.g. a bath-lift, when the unit and the chassis are detached; and the chassis has hand operated wheel-brakes and an automatic actuating mechanism to apply the brakes when the seat is raised.
Claims11
A wheelchair assembly comprising:
- (a) four manually separable units including a chassis having wheels, a lifting device releasably mounted on said chassis, seat means releasably mounted on said lifting device, and a power unit removably stowed on said chassis, wherein the power unit is separable from the lifting device,
- (b) said lifting device including a base releasably securable to said chassis by a manually actuable locking mechanism, and a platform supported above said base by internally stabilized lifting means disposed between the platform and the base for raising and lowering the platform relative to the base,
- (c) the seating means including a carrier frame releasably secured by manually actuable retaining means to said platform,
- (d) the power unit and lifting device are operatively connected by manually detachable connecting means, and
- (e) said manually actuable locking mechanism, said manually actuable retaining means and said manually detachable connecting means are manually actuable to enable each of the lifting device and power units to be lifted from the assembly and to be reconnected together by the manually detachable connecting means for use as a bath lift apparatus without the chassis and seating means.

A combined wheelchair and bathlift assembly in which
- (a) the wheelchair comprises a chassis having wheels, a lifting device on said chassis, seating means releasably mounted on said lifting device, and a power unit separable from the lifting device,
- (b) said lifting device including a base securable by a manually actuable locking mechanism to said chassis, and a platform supported above said base by stabilized lifting means disposed between the platform and the base for raising and lowering the platform relative to the base,
- (c) the seating means including a backrest mounted on a rear end of the platform of the lifting device, and a carrier frame releasably mounted on the platform for supporting armrests and legrest means,
- (d) the base including suction cup means to adhere to the bottom of a bath, and the carrier frame and wheeled chassis are separable from the lifting device so that the lifting device can be placed intact in a bath with the backrest in situ to serve as a bathlift,
- (e) the power unit is stowable in and liftable from the wheeled chassis and is operatively releasably connectable to the lifting device, both when the lifting device forms part of the wheelchair and when the lifting device is separated from the chassis and carrier frame, by manually detachable connecting means, for operating the lifting device.
