Abstract

Abstract A carriage has a plurality of ground engageable wheels (206) mounted on a body (200), and a pair of driving wheels (233, 234) independently drivable by drive motors (226, 227). The driving wheels (233, 234) are movably mounted on a chassis (214) so that they can occupy a first position clear of the ground to enable the carriage to be driven over the ground. The carriage may include a seat (210) which can be elevated and tipped forwardly by motor driven actuators (273), (266) to enable the height of the seat (210) to be adjusted and to assist a user to move from the seat (210) into a standing position.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 91 words
A carriage comprising a plurality of ground engageable wheels (14, 206) mounted on a body (10; 200) at least one drivable wheel (39, 40; 233, 239), and drive means (44, 47; 226, 227) for said drivable wheel characterised in that the or each drivable wheel (39, 40; 233, 239) is so mounted (10; 200) that it can occupy a first position clear of the ground and a second position in engagement with the ground whereby the carriage can be driven over the ground by the drivable wheel (39, 40; 233, 239).
Claim 2
Dependent Claim 91 words
A carriage comprising a plurality of ground engageable wheels (14, 206) mounted on a body (10; 200) at least one drivable wheel (39, 40; 233, 239), and drive means (44, 47; 226, 227) for said drivable wheel characterised in that the or each drivable wheel (39, 40; 233, 239) is so mounted (10; 200) that it can occupy a first position clear of the ground and a second position in engagement with the ground whereby the carriage can be driven over the ground by the drivable wheel (39, 40; 233, 239).
Claim 3
Dependent Claim 27 words
A carriage according to Claim 1 characterised in that two drivable wheels (39, 40; 233, 239) are drivable independently by said drive means (44, 47; 226, 227).
Claim 4
Dependent Claim 55 words
A carriage according to Claim 1 or 2 characterised in that the body (10, 200) carries a load carrying portion (51; 251) and the movement of the or each drivable wheel (39, 40; 226, 227) into engagement with the ground is effected as a result of a load being applied to the load carrying portion.
Claim 5
Dependent Claim 35 words
A carriage according to Claim 1, 2 or 3 characterised in that the or each drivable wheel is carried by a section (25, 214) mounted for up and down movement on the body (10; 200).
Claim 6
Dependent Claim 64 words
A carriage according to Claim 4 characterised in that resilient means (31, 223) is arranged between said section (25; 214) and the body (10; 200) so that when a downward load is applied to said section to move the or each drivable wheel (39, 40; 233, 239) into engagement with the ground, the load is arranged to overcome the bias of the resilient means.
Claim 7
Dependent Claim 40 words
A carriage according to Claim 4 or 5 characterised in that the section (214) is pivotally connected to the body (200) by arm means (217) whereby up and down movement of the drivable wheels (233, 239) pivots said arm means.
Claim 8
Dependent Claim 23 words
A carriage according to Claim 6 characterised in that the arm means comprises two spaced apart arms (217) rigidly connected to said section.
Claim 9
Dependent Claim 27 words
A carriage according to Claim 6 or 7 characterised in that the section carries two independently operable driving motors (226, 227) for the drivable wheels (233, 234).
Claim 10
Dependent Claim 39 words
A carriage according to Claim 6, 7 or 8 characterised in that the section (214) supports the lower end of part of a vertical column (209) on the upper end of which a load carrying portion (210) is mounted.
Claim 11
Dependent Claim 31 words
A carriage according to any preceding Claim characterised in that where a load carrying portion (51, 210) is provided motorised elevating means (50; 273) is provided for the load carrying portion.
Claim 12
Dependent Claim 55 words
A carriage according to any preceding Claim characterised in that where a load carrying portion is provided, the load carrying portion is in the form of a seat (51, 210) and motorised tipping means (110; 266) is provided for tipping the seat to assist a user in moving from the seat into a standing position.
Claim 13
Dependent Claim 30 words
A carriage according to Claim 11 characterised int hat the motorised tipping means (110; 266) is actuated after the load carrying portion has been elevated to its highested elevation position.
Claim 14
Dependent Claim 58 words
A carriage according to any preceding Claim characterised in that where a load carrying portion in the form of a seat (51, 210) is provided, the seat includes a leg rest (79; 247) and motorised adjustment means (83; 247) is provided to adjust the position of the leg rest (79; 245) relative to the remainder of the seat.
