Definitions
- the present invention relates to a commode chair for facilitating use of toilet facilities or chamber pots, a shower chair for use in personal cleaning while in a sitting position as required by disabled aged or injured or infirm users and to a combined shower commode which can be used for both purposes.
- the present invention can be in the form of a stationary chair or trolley form or in particular to a wheeled commode chair able to transport the user.
- the invention has been developed primarily for use as a wheeled shower commode chair and will be described hereinafter with reference to this application. However, it will be appreciated that the invention is not limited to this particular field of use. Background of the Invention
- Commode chairs are known for use as aids for disabled or physically limited persons to use in order to use toilet facilities.
- Primarily commode chairs are a portable toilet carrying receptacle that can be placed at the bedside of a patient whose activity is limited.
- a commode chair is frequently used in the home when a patient is too debilitated to reach a bathroom facility, and the receptacle receives waste, and the receptacle can be removed and emptied.
- Commode chairs are usually fixed cumbersome chairs which are therefore not generally intended for use with normal toilet facilities. Some chairs that overlie normal toilet facilities are lifted into position over the toilet, and then require the user to mount the higher commode chair.
- the commode chair tends to be very unstable and is easily misaligned. A user therefore needs more stable support, often this is provided in the form of arm supports or back rest supports.
- a commode adapted for use by one person may not be practical or effective for another person with different physical attributes and requirements, and physical disability.
- a commode chair which is stable for a tall or large person with all limbs may not be stable when used by an amputee.
- Existing commodes therefore need to be manufactured to meet particular requirements resulting in a large range of chairs. It would be advantageous to provide a universal commode chair.
- the present invention seeks to provide a commode chair, which will overcome or substantially ameliorate at least one or more of the deficiencies of the prior art, or to at least provide a viable alternative.
- a commode chair comprising a pair of spaced parallel side walls; at least one cross-member structure joining the pair of spaced parallel side walls in structural support; wherein a central cavity applies between the side walls and the front and rear cross-member structures over which a commode seat can support a user of the commode chair.
- the commode chair can further comprise spaced apart front and rear cross- member structures being attached between opposite side frame portions, forming a two- part structure.
- the rear cross-member can be a substantially straight connector structure mounted to opposite side frames. The location of the straight rear connector can provide a bridge and a rear passageway so that the commode chair can be reversed over a normal toiled facility.
- the spaced parallel side walls can be parallel side frames.
- the commode chair can further include a connection means for selectively supporting the parallel side frames in a spaced operating condition, and releasing to a fold down position upon which the parallel side frames are in a reduced spaced non- operating condition.
- connection means can be a hinge.
- the pair of spaced parallel side frames are adapted to be supported at least partially on wheels.
- the pair of spaced parallel side frames can be adapted to be supported front and rear wheels to form a wheel chair able to transport a user.
- the commode chair has at least one of the front and rear cross- member structures are substantially at seat level wherein the commode chair can be wheeled over a toilet receptacle.
- the commode chair can further comprise a releasable locking means for allowing locking of the two-part structure in an operating condition, and release to a fold down position upon release of the locking means.
- the front cross-member includes: a first and second hingedly attached cross-arm members, the each cross-arm member being further hingedly attached at one end thereof to a fixed portion of the opposite side frames; and wherein the first and second cross-arm members are adapted to move between a fold out and folded position.
- first and second cross-arm members of the front cross- member form a substantially X-shaped configuration when the front cross-member is in the fold out position.
- the releasable locking means is such that the first and second cross-arm members forming a substantially X-shaped configuration are maintained in the fold out position by locking the rear cross-member and when the locking means is released from a locking condition, the side frames can be moved closer to each other for storage.
- the commode chair further comprises cross-members both front and rear, joining opposite wheeled side frames, wherein the cross-members are hingedly interconnected to respective side frames to provide structural support when the rear cross-member is in a locked condition, and folding of the front and rear cross- members for storage when the rear cross-member is unlocked, preferably comprising a distinctive 'X-configuration' of the front cross-member.
- the commode chair can further comprise an 'axle reverse amputee' bracket, which supports the axle, and allows adjustment of the axle so the centre of gravity is adjustably located 80 - 90 millimetres rearwards of a normal position.
- 'axle reverse amputee' it is meant a bracket that supports the axle that can be adjusted so the centre of gravity is adjustably located 80 - 90 mm rearwards of a normal position to compensate for the different spread of weight-load by an amputee comparative to a non-amputee.
- the commode chair can further comprise a seat frame or side frame which includes a cut-out section to allow access for cleaning and the like.
- the seat frame does not have to be taken off for folding the commode chair.
- the arm rest can be height adjustable.

- a commode chair 1 1 comprising a frame 15 formed with a pair of spaced parallel side frames 21 , 22 that are supported on a pair of outer large wheels 18 extending parallel on an outer side to the parallel side frames 21 , 22 and a pair of smaller front wheels 19 connected to a front portion of the parallel side frames 21 , 22.
- the chair further has an upright posts 62, 63 at the rear of each of the parallel side frames 21 , 22 which receives a rigid inverted U-shaped frame 61 that mounts over the posts 62, 63.
- the inverted U-shaped frame 61 include flexible straps between the opposing legs of the inverted U-shape and thereby form a removable backrest 61 .
- figure 1 1 there is shown an angled back rest with adjustable height.
- a set of armrests 69 are provided that form an upper part of each of the spaced parallel side frames 21 , 22.
- the armrests extend from a rear portion of the spaced parallel side frames 21 , 22 and extend forward to support arms in a cantilever manner. This provides the benefit of minimal material and ready cleaning of the commode chair as well as side access to the user by a carer if required.
- the commode chair can proceed from an in use position such as shown in Figure 1 to a storage position such as shown in Figures 9 and 10 by the front and rear cross-member structures being hingedly foldable from an extended position to an overlapping smaller storage position.
- This first element of the cross-member structures 51 , 55 allows the ready implementation from an in use position to a storage position and vice versa and will be explained further below.
- a second element of the cross-member structures 51 , 55 is that at least one of the front and rear cross-member structures 51 , 55 must connect between top portions of the parallel side frames 21 , 22 at either a front end and or a rear end and have minimal suspended structure so as to form a bridge between the parallel side frames 21 , 22 and define a passageway 35 therebelow.
- the cross-member structure 55 connects at the rear of the commode 1 1 between the parallel side frames 21 , 22 and forms a bridge therebetween with a passageway 35 below.
- the passageway 35 leads into the open cavity 31 formed between the side frames 21 , 22 and the front and rear cross-member structures 51 , 55. This is further shown in the overhead view of Figure 6.
- a commode seat 17 can be supported at each side by the parallel side frames 21 , 22 so that a user of the commode chair 1 1 can sit over the open cavity 31 .
- the user of the commode seat 17 can undertake toilet functions. Therefore the bridge structure allows the commode chair to be manually positioned over the toilet in an acceptable front facing chair arrangement.
- the further benefit of the support of the commode seat being on a mobile frame 15 supported by large wheels 18 and smaller front wheels 19 is a first element which allows a simple wheeled location of the commode chair to the required functionally corresponding location of commode seat relative to the toilet.
- the wheeled structure of the wheeled version of the commode chair 1 1 allows positioning with the user in situ on the commode seat 1 7.
- each of the parallel side frames 21 , 22 has a large wheel 18 attached to an outer side and in the same parallel alignment as a respective side frame and a rotatable castor like small front wheel attached to a front portion of the respective side frame. This allows spaced locations of the parallel side frames 21 , 22 which allow positioning on either side of the toilet. Further the configuration of the passageway 35 below the bridge formed by the cross-member structure 55 connecting at the rear of the commode 1 1 between the parallel side frames 21 , 22 allows the wheeled commode seat to be wheeled backwards over the toilet with the user facing in the normal direction away from the wall.
- the set of armrests 69 mounted to form an upper part of each of the spaced parallel side frames 21 , 22 also perform a secondary function.
- the armrests 69 are cantilever mounted and extend forwardly along the spaced parallel sides and end with front handles 64. These handles 64 allow a carer to be positioned in front of the chair with the user seated on the commode seat 17 on the commode chair and allow the carer to wheel the commode chair 1 1 over the toilet by aligning the large rear passageway 35 and the rear cross-member structure 55 acting as a bridge that passes over the toilet.
- An important element of an embodiment of the invention is when the commode chair is also a wheel chair.
- Another element which aids in this process are a set of handles 69 extending from the frame 15 including the seat back 61 towards the front of the commode chair 64. Therefore the user can be assisted by a helper in pushing the commode chair from in front of the chair over a toilet.
- These handles 64 can double as arm rests for the user in other uses of the wheeled chair.
- the structure of the commode chair 1 1 has been shown to have substantial structural benefits for the user in an in use expanded form. However the chair 1 1 has a further benefit in its foldability.
- the two side frames 21 , 22 each are mounted on respective large side wheels 18 and front small balancing and steering castor wheels 19 and is similarly supported in the folded form as shown in Figures 9 and 10. This means that the chair is readily transportable. [0055] Even if the commode chair was not a wheeled chair the side frames 21 , 22 would be supported by the same legs as support the side frame in the expanded in use form.
- Figures 7 and 8 show how the wheeled commode chair can transform from the expanded in use form of Figures 1 , 2 and 3 to the folded form of Figure 10.
- Figure 7 shows the removal of the locking backrest 61 that fits into respective upright pillars 62, 63 on respective side frames 21 , 22.
- the backrest provides the service of a backrest to the user and a means for a carer to help the user of the chair by pushing the chair from behind.
- the backrest has a rigid inverted U-shaped frame which is fixed in length and the backrest is completed with comfort flexible slats extending across the frame. This rigid fixed length frame when inserted in the respective upright pillars 62, 63 keeps the respective side frames 21 , 22 the fixed distance apart from each other.
- the respective side frames are held apart by the first and second hingedly attached cross-arm members 51 , 55.
- These cross members have support bars extending between them to Y and Z directions while the vertically extending second cross-arm member 51 forming a substantially X-shaped configuration when maintained in the fold out position provides the X and Y directional rigidity. Therefore the structure is rigid in three dimensions when in locked position.
- the commode chair is versatile and useable by a range of users.
- the commode chair can be modified for amputees. This is important in a wheeled version as the bulk of the weight of the user is over the large side supporting wheels 18.
- the centre of gravity of the user is slightly forward of the diameter of the main wheels 18 and leaning slightly towards the smaller front directional castor wheels 19. This will prevent tipping backwards of the chair while allowing ready steering of the chair as the front castor wheels are not subjected to too much weight.
- the seat frame or side frame can include a cut-out section to allow access for cleaning and the like. ⁇ the seat frame does not have to be taken off for folding the commode chair.
- a swing away foot plate wherein the foot plate is for receiving feet of a user and are adjustable to swing away to allow user's feet to contact with ground.
- a commode chair for facilitating use of toilet facilities or chamber pots, or b) to a shower chair for use in personal cleaning while in a sitting position as required by disabled aged or injured or infirm users or
- the "commode chair” can be in the form of a stationary chair or trolley form or in particular to a wheeled commode chair able to transport the user.
- any one of the terms: including or which includes or that includes as used herein is also an open term that also means including at least the elements/features that follow the term, but not excluding others. Thus, including is synonymous with and means comprising.
