- the lap strap 160 also assists in holding the wheelchair 110 in its storage condition, as shown in figure 4 .
- the wheelchair 10, 110 is advantageous over prior art wheelchairs in many ways. For example, in order to fold or collapse some prior art wheelchairs to their storage condition, it is necessary to apply a downward pressure to the seat of the wheelchair, after a lock or safety mechanism has be deactivated. If the lock or safety mechanism is not correctly activated prior to the wheelchair being used, it is thus possible for the wheelchair to collapse/fold upon a person mounting the wheelchair, which could lead to injury.
- the footrests require to be positioned manually once the wheelchair has been unfolded, which is time-consuming. Often the footrest(s) is/are not deployed at all, or not deployed correctly, which means that the wheelchair user may have difficulty in positioning his/her feet. This could result in discomfort to the wheelchair user or possibly injury due to the increased pressure on the user's thighs. In addition, on prior art wheelchairs the footrests project outwardly beyond the periphery of the wheelchair frame structure, which is undesirable as a person walking past the wheelchair could hurt his/her legs on the projecting footrests.
- the wheelchair 10, 110 described above has a pair of footrests 32, 132, it could be provided with one footrest which has a large enough foot support 33, 133 to support two feet, but which is still moveable in the same was as the footrests 32, 132.
Abstract
Description
- This invention relates to a wheelchair.
- Wheelchairs are often used in environments where space is a premium. One example is the interior of an aircraft. Aircrafts are typically provided with an onboard wheelchair which can be used by non-able-bodied passengers to assist them in travelling from their aircraft seat to an onboard toilet. The prior art wheelchairs which have been designed for this purpose are over-engineered and due to their construction take up too much space when stored on the aircraft.
- It is therefore an object of the invention to provide an improved wheelchair which addresses the above issues.
- Therefore, according to a first aspect of the invention, we provide a wheelchair including a pair of side frames and at least one footrest, each side frame having a lower frame part and an upper frame part which are moveable relative to each other between a 'storage' condition, in which an uppermost part of each upper frame part is positioned remotely from its respective lower frame support, and an 'in use' condition, in which the uppermost part of each upper frame part is positioned closer to its respective lower frame part, wherein movement of the upper frame parts from their 'storage' condition to their 'in use' condition effects movement of the footrest to a deployed condition.
- Further features of the invention are listed in
claims 2 to 6 appended hereto. - Non-limiting embodiments of the invention will now be described by way of example only with reference to the accompanying drawings, of which:-
-
Figure 1 is a perspective view of a first embodiment of a wheelchair in accordance with the invention in an 'in use' condition; -
Figure 2 is a further perspective view of the first embodiment of the wheelchair in accordance with the invention in a 'storable' condition. -
Figure 3 is a perspective view of a second embodiment of a wheelchair in accordance with the invention in an 'in use' condition; and -
Figure 4 is a further perspective view of the second embodiment of the wheelchair in accordance with the invention in a 'storable' condition. - Referring to
figures 1 and2 , there is a shown a wheelchair in accordance with the invention, generally at 10. Thewheelchair 10 is manufactured from a plurality of tubular members, each of which is made from an Aluminium alloy, and is circular in cross-section. However, it must be appreciated that thewheelchair 10 could be made from any desired material, so long as it is strong enough to support the wheelchair user. - The
wheelchair 10 includes twoside frames cross members 18. Theside frame 16 is a mirror image of theside frame 14, and thus for clarity only theside frame 14 will be discussed in detail. - The
side frame 14 comprises alower frame part 14a and anupper frame part 14b, which are telescopically slideable relative to each other. Thelower frame part 14a is substantially U-shaped, i.e. it has twoupright members 14d, 14e, which are substantially parallel to each other and which are connected at their lower ends by a connecting member 14c. Each end of the connecting member 14c supports acastor wheel 20. - The
upper frame part 14b is substantially h-shaped, i.e. it has two substantiallyupright members 14f, 14g, which are substantially parallel to each other and which are connected by a connectingmember 14h. In the present example the member 14g is a continuation of connectingmember 14h. Hingeably connected (for compact storage purposes) at 24 to the upper end of themember 14f is ahandle 22 to aid in pushing or pulling of thewheelchair 10. - The downwardly facing free ends of the
members 14f, 14g of theupper frame part 14b are provided with recesses to receive the upwardly facing free ends of themembers 14d, 14e of thelower frame part 14b. Thus the upper 14b and the lower 14a frame parts are telescopically slideable relative to each other. Of course, it must be appreciated that, instead of the above configuration, the upwardly facing free ends of themembers 14d, 14e could be provided with recesses to receive the downwardly facing free ends of themembers 14f, 14g. - One
cross member 18 is pivotally connected at one end to the connecting member 14c of thelower frame part 14a and pivotally connected at its opposite end to the connectingmember 16h of theupper frame part 16b. Theother cross member 18 is pivotally connected at one end to the connectingmember 14h of the upper frame part 16a and pivotally connected at its opposite end to the connecting member 16c of the lower frame part 16a. Thecross members 18 are pivotally connected to each other at the mid-region between their ends. - Although not shown in
figures 1 and2 , thewheelchair 10 includes a seat which extends between connectingmembers upper frame parts figure 3 , for example). The seat is made from a flexible material, e.g. a plastics composite material, although any appropriate material could be used. - The
wheelchair 10 includes a pair of self-transfer members member 12a is connected to the connectingmember 14h of theupper frame part 14b and theother member 12b is connected to the connectingmember 16h of theupper frame part 16b. Themember 12b is a mirror image of themember 12a, and thus for clarity only themember 12a will be discussed in detail. - The
member 12a is substantially planar and includes a U-shaped frame 26. Connected to the U-shaped frame 26 is a substantially rigid sheet 27, e.g. an aluminium sheet (although any other appropriate material could be used, e.g. a plastics material). The U-shaped frame 26 is pivotally connected to the connectingmember 14h of theupper frame part 14b by a pair ofhinges 30, and is moveable between a first position (that of themember 12b as shown in the figures) and a second position (that of themember 12a as shown in the figures). In the first position themember 12a is substantially vertical and provides a side wall to a seat region of thewheelchair 10. - In the first position a part of the U-shaped frame 26 also provides an armrest for a user of the
wheelchair 10. Themember 12a is lockable in the first position by a lock mechanism indicated at 34. - In the second position the
member 12a is pivoted outwardly away from a centreline of thewheelchair 10 so as to engage an object, e.g. an aircraft seat. In the second position the aluminium sheet 27 provides a self-transfer surface over which the wheelchair user can move. In the second position the sheet 27 and the seat (not shown) provide a substantially continuous surface which assists the wheelchair user to self-transfer. - The
wheelchair 10 also includes a pair offootrests 32 which are a mirror image of each other. Thus, only thefootrest 32 connected to theside frame 16 will be discussed in detail. - The
footrest 32 includes aU-shaped foot support 33. Each end of the U-shapedfoot support 33 is provided with a sleeve which is slidably received on a rod ortube 35. Connected to the rod ortube 35, at a mid-region thereof, is a support rod ortube 36, which extends away from the rod ortube 35 towards theside frame 16 where it is pivotally connected at 37 to an upper region of theframe member 16b. Pivotally connected at 38 to a mid-region of the rod ortube 36 is anelongate link member 39. The opposite end of thelink member 39 has anelongate aperture 40 which receives a projectingmember 41, which projectingmember 41 is connected to the frame member 16c. - The first embodiment of the
wheelchair 10 is operated as follows. - When the
wheelchair 10 is in the storage condition, as shown infigure 2 , and it is desired to use thewheelchair 10, all that is required is for the user to push downwardly on one or both of theupper frame parts members upper frame parts lower frame parts 14a, 16a. Due to the pivotal connection of thecross members 18 to each other and to the upper andlower frame parts upper frame parts side frames side frames members 14d, 14e, 16d, 16e of thelower frame parts members 14f, 14g, 16f, 16g of theupper frame parts side frames - Downward movement of the
upper frame parts footrests 32. Due to the connection of thelink member 39 to the rod ortube 36, when theupper frame parts lower frame parts 14a, 16a, the rod ortube 36 is pivoted outwardly away from itsrespective side frame footrests 32 continue to move away from theside frame members 14d, 14e, 16d, 16e of thelower frame parts members 14f, 14g, 16f, 16g of theupper frame parts tube 36 extends away from itsside frame wheelchair 10. The user then pivots each foot support 33 about its respective rod ortube 35 until the foot support is in a desired position (e.g. usually slightly inclined to the ground surface). - In order to return the wheelchair to its storage condition, it is necessary to effect movement of the uppermost parts, in this case the connecting
members upper frame parts lower frame parts 14a, 16a. This is most easily achieved by lifting one or both of theupper frame parts members lower frame parts 14a, 16a, and thecastor wheels 20 connected thereto, thelower frame parts 14a, 16a will tend to remain close to the ground surface when theupper frame parts cross members 18 to each other and to the upper andlower frame parts upper frame parts wheelchair 10 to its storage condition. At the same time thefootrests 32 are pivoted downwardly and inwardly to their storage condition, positioned adjacent each other and between the side frames 14, 16, due to the linkage arrangement between the rod ortube 36 and the link member 39 (it is necessary for the foot supports 33 to be pivoted to their storage condition before one or both of theupper frame parts - Referring to
figures 3 an 4, these show a second embodiment of awheelchair 110 in accordance with the present invention. Thewheelchair 110 is identical in many respects to thewheelchair 10. Thus, like/equivalent component parts have been given the same reference numeral, but with the addition of 100. - The
wheelchair 110 differs mainly from thewheelchair 10 in the connection of itsfootrests 132 to theside frame 116. In thewheelchair 110, the support rod ortube 136 extends away from the rod ortube 135 towards a lower end of theside frame 116 and is pivotally connected at 141 to a lower region of theframe member 116b. Pivotally connected at 138 to a mid-region of the rod ortube 136 is anelongate link member 139. An opposite end of thelink member 139 is pivotally connected at 137 to an upper region of theframe member 116b. - Thus, in the
wheelchair 110, the juxtaposition of the rod ortube 136 and theelongate link member 139 mean that when thewheelchair 110 is moved to its storage condition thefootrests 132 pivot upwardly and inwardly to their storage condition, positioned adjacent each other and between the side frames 14, 16. - The
wheelchair 110 also includes alap strap 160 for assisting in securing a person in the wheelchair. Such a lap strap could, of course, be provided on thewheelchair 10. Thelap strap 160 also assists in holding thewheelchair 110 in its storage condition, as shown infigure 4 . - The
wheelchair - Furthermore, in prior art wheelchairs the footrests require to be positioned manually once the wheelchair has been unfolded, which is time-consuming.
Often the footrest(s) is/are not deployed at all, or not deployed correctly, which means that the wheelchair user may have difficulty in positioning his/her feet. This could result in discomfort to the wheelchair user or possibly injury due to the increased pressure on the user's thighs. In addition, on prior art wheelchairs the footrests project outwardly beyond the periphery of the wheelchair frame structure, which is undesirable as a person walking past the wheelchair could hurt his/her legs on the projecting footrests. - Having footrests which are deployed automatically, when the wheelchair is moved to its 'in use' condition, and which are substantially concealed when in the storage condition, therefore reduces the likelihood of the above problems occurring.
- Although the
wheelchair footrests enough foot support footrests - When used in this specification and claims, the terms "comprises" and "comprising" and variations thereof mean that the specified features, steps or integers are included. The terms are not to be interpreted to exclude the presence of other features, steps or components.
- The features disclosed in the foregoing description, or the following claims, or the accompanying drawings, expressed in their specific forms or in terms of a means for performing the disclosed function, or a method or process for attaining the disclosed result, as appropriate, may, separately, or in any combination of such features, be utilised for realising the invention in diverse forms thereof.
