Abstract
A wheeled chair includes a square base unit 10 with castor wheels 14 at each corner, a three stage telescopically extending column 11 extending from the base and a seat mounted at the upper end of the column. A footrest 13 is attached to the seat 12. The chair is provided with a remote control to control the motors responsible for extending/retracting the column. Also disclosed is an 'intelligent' charger for the battery powering the chair. The chair is intended to be dismantleable and to fit in a vehicle boot.
Description
2351018 WHEELED CHAIRS
Field of the Invention
This invention relates to wheeled chairs.
When a person is in a wheelchair, conversations tend to take place with the carer who is pushing the wheelchair rather than with the person in the wheelchair, who is at a different height and therefore tends to be ignored. This can be very frustrating, and it is accordingly an object of the present invention to provide an improved form of wheeled chair, the design of which is such as to enable this problem to be overcome.
Summarv of the Invention According to the present invention, there is provided a wheeled chair comprising:- a) a wheeled base, b) a telescopically extendible column extending upwardly from the base, c) a seat mounted on top of the column, d) a footrest depending from the seat, e) motor means for effecting extension and contraction of the column, and remote control means for controlling operation of the motor means, The telescopically extendible column is preferably a threestage column such that, when the column is fully extended, the height thereof is at least approximately twice the height thereof in its contracted condition.
The remote control means will thus preferably be such that, when the person sifting in the chair wishes to increase the height of the chair, he or she will press a button on the remote control, to effect extension of the column to the required height.
The wheeled base is preferably of substantially square form in plan view, with wheels adjacent the four corners of the base, and at least two of the wheels are preferably castor wheels to facilitate manoeuvring of the chair by a carer.
The seat mounted on the column preferably includes a squab, a backrest portion and a pair of armrests which are so designed that the wheeled chair is aesthetically compatible with, for example, dining chairs and office chairs so that the person in the wheeled chair can sit at a table with a number of other people without looking out of place.
Brief Description of the Drawlims
Figure 1 is an isometric view of a wheeled chair with the seat in its lowered position, 3 Figure 2 is a view corresponding to Figure 1, but with the seat in its raised position, and Figure 3 is a plan view of the base unit of the chair.
Descriffion of the Preferred Embodiment The chair shown in the drawings has been designed to enable those who are physically limited in their mobility, whether temporarily or for an extended period, to take a normal part in business and social events with the minimum of inconvenience and embarrassment.
At its lowest setting, as shown in Figure 1, the chair gives the impression of being a normal armchair of standard seat height. This enables the occupant to take a full and normal part at seated functions such as dinners, meetings and other social occasions. At its highest setting, as shown in Figure 2, the occupant of the chair is raised so that he or she can take a full part in standing functions, such as receptions, cocktail parties or normal day-to-day conversations.
The chair shown in the drawings is so designed that it can be dismantled and fitted into the boot of a motor vehicle. The chair thus includes four separable parts, i.e. a base unit 10, a column unit 11, a seat unit 12 and a footrest unit 13. The base unit 10 is of generally square form in plan view with castor wheels 14 at each of the four corners of the base unit 10. The base unit 10 includes a 4 compartment 15 in which a rechargeable battery is located. The chair is provided with an "intelligent" battery charger (not shown) which will maintain the battery in good condition and ready for use.
To recharge the battery, the charger is first connected to the mains supply, at which time a red light on the charger will be lit to show that the charger is connected to the mains supply. The charger is then plugged into a socket on the chair, at which time a second red light will be lit. The charger provides a rapid charge to bring the battery up to the correct level and then changes to a trickle charge to maintain that level over a long period. Thus, when the battery has reached its full charge, a green light will be lit and the second red light will slowly disappear as the battery charger changes over to a long-term trickle charge.
The column unit 11 comprises three telescopically movable sections of rectangular form in plan view and one or more motors (not shown) are provided for effecting extension of the column from the retracted condition shown in Figure 1 to the extended condition shown in Figure 2, in which the height of the column is approximately twice that of the unextended column. A cable 16 terminating in a connector 17 is provided for connection of the motor(s) to the battery.
To connect the column unit 11 to the base unit 10, wingnuts and washers (not shown) are removed from four studs (not shown) in the middle of the base unit 10. The column unit 11 is then lowered over the four studs of the base unit 10 ensuring that it is seated correctly and that the cable 16 is positioned in the cavity of the base unit 10 in the manner shown in Figure 3. The four washers and wingnuts are replaced and tightened to fix the column unit 11 in position and the column connecting plugs are then plugged into the sockets in the base unit 10.
Six downwardly projecting studs (not shown) are provided beneath the seat unit 12. Four of these studs are aligned with corresponding apertures of a flange around the top of the uppermost section of the column unit 11. Washers and wingnuts are placed on these studs and the wingnuts tightened to secure the seat unit 12 in position on top of the column unit 11.
The footrest unit 13 includes a bracket formed with a pair of apertures which are spaced apart a distance corresponding to the spacing of the other two studs extending downwardly beneath the seat unit 12. The bracket is placed in position with the studs projecting through the apertures in the bracket and wingnuts are tightened on to the studs to fix the footrest unit 13 in position. As can be seen from Figure 1, the footrest unit 13 includes an inclined strut 19A which is adjustable in length and is fixed at the required length by tightening a knob 18.
To operate the chair, the power supply is switched on using the "On/OfF' switch 19 and a red indicator light 20 is then actuated. The user of the chair has a key-fob type remote control unit (not shown) which includes two pressure pads. Up and down movement of the seat unit 12, i.e. extension and retraction of the column unit 6 11, is controlled by pressing one or other of the two pressure pads on the key-fob unit to move the seat unit 12 to the required level. The column unit 11 will stop automatically at the top and bottom limits of its travel, the motor(s) controlling operation of the column unit 11 being provided with control circuitry which will cut out automatically if the column is overloaded.
It will thus be seen that the user of the chair is able to adjust the height of the seat unit 12 as required and will, therefore, be able to take part in conversations with those who are standing up equally as well as with those who are sitting down.
