Commode chairs are conceived to assist disabled or limited persons in using toilet facilities. A commode chair is primarily a portable toilet with a container that can be placed next to the bed of a patient with limited mobility.

Commode chairs are often used at home when the patient is too infirm to reach the bathroom facility, the receptacle receives the waste and the receptacle can be removed and emptied.

Commode chairs are usually fixed, bulky chairs and as such are not usually used in normal toilet facilities. Some of the chairs that cover the normal toilet facilities are lifted above the toilet and the user is then asked to ride on the higher toilet chair.

In such a position, the commode chair is unstable and prone to misalignment. As a result, users require more stable support, usually in the form of arm supports or back supports.

Overall, this is not a system that gives the user a sense of security and dignity, and is difficult to install on a toilet.

Still further, a toilet that is suitable for one person may not be practical or effective for another person with different physical attributes and requirements and physical disabilities. For example, a commode chair that is stable for a tall, able-bodied person may be unstable when used by an amputee. Therefore existing toilets need to be manufactured to meet specific requirements, resulting in a large number 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 improve at least one or more of the deficiencies of the prior art, or at least provide a viable alternative.

It should be understood, however, that other embodiments may have combinations of one or more of these features and still provide a substantial novel improvement, and are included within the scope of the present invention.

use structure

Referring to the drawings, there is shown a commode chair 11 comprising a frame 15 formed from a pair of spaced apart parallel side frames 21, 22 supported on parallel side On the outside of the frames 21 , 22 run in parallel a pair of large outer wheels 18 and a pair of smaller front wheels 19 connected to the front of the parallel side frames 21 , 22 .

Connecting the parallel side frames 21 , 22 are spaced front and rear cross member structures 51 , 55 to incorporate the pair of spaced parallel side frames 21 , 22 in structural support. In the open position for use as shown in FIGS. 1 and 2, a central cavity 31 is formed between the side frames 21, 22 and the front cross-member structure 51 and the rear cross-member structure 55, on which the The central open toilet seat 17 can support the user of the toilet chair 11 .

The commode chair also has uprights 62 , 63 at the rear of each parallel side frame 21 , 22 , and the uprights 62 , 63 receive a rigid inverted U-shaped frame 61 mounted on the uprights 62 , 63 . The inverted U-shaped frame 61 includes flexible straps positioned between opposing legs of the inverted U, forming a removable backrest 61 . In Fig. 11, an angled backrest with adjustable height is shown.

A set of armrests 69 is provided forming the upper part of each spaced apart parallel side frame 21 , 22 . Armrests extend from the rear of the spaced parallel side frames 21, 22 and cantilever forward to the support arms. This provides the benefits of minimal material and ease of cleaning the commode chair, as well as side access to the user by a caregiver if desired.

As shown in Figure 1, the commode chair can be moved from the use position to the storage position as shown in Figures 9 and 10 by the front cross member structure and the rear cross member structure, wherein the front cross member structure and the rear cross member structure The structure can be hingedly folded from an extended position to an overlapping smaller storage position. The first element in the cross member 51 , 55 allows quick access from the use position to the storage position and vice versa, and will be explained further below.

The second element in the cross member structure 51 , 55 , at least one of the front cross member structure 51 and the rear cross member structure 55 must be connected at the front and/or rear end between the tops of the parallel side frames 21 , 22 , and have a minimum suspension structure so as to form a bridge between the parallel side frames 21, 22 and define a channel 35 below them.

Referring to the schematic diagrams of Figures 4 and 5 to illustrate the toilet chair 11 of Figure 1, the cross member structure 55 is connected at the rear of the toilet chair 11 between the parallel side frames 21, 22 and forms therebetween the toilet chair 11 with the channel 35 underneath. bridge. The channel 35 leads into an open cavity 31 formed between the side frames 21 , 22 and the front cross member structure 51 and the rear cross member structure 55 . This is further shown in the top view of FIG. 6 .

The toilet seat 17 may be supported on each side by parallel side frames 21 , 22 such that a user of the commode chair 11 may sit on the open cavity 31 . By placing the toilet seat on the toilet container, the user of the toilet seat 17 can perform toilet functions. Thus, the bridge structure allows the commode chair to be manually positioned over the toilet in an acceptable front seat arrangement.

Rotation

A further benefit of the support of the toilet seat on the mobile frame 15 supported by the large wheels 18 and the smaller front wheels 19 is the first element that allows the simple wheeled position of the commode chair to the position of the toilet seat relative to the toilet bowl. The desired function corresponds to the location. Unlike the manual position of non-wheeled versions of the commode chair 11 , the wheeled construction of the wheeled commode chair 11 allows the user to position on the toilet seat 17 in place.

A particular advantage is that each parallel side frame 21, 22 has a large wheel 18 connected to the outside of the corresponding side frame and in the same parallel alignment, and to the front side of the corresponding side frame. The swivel castors on the front resemble small front wheels. This allows for spaced positions of the parallel side frames 21, 22 positioned on either side of the toilet. Furthermore, the configuration of the channel 35 below the bridge formed by the cross-member structure 55 connected between the parallel side frames 21, 22 at the rear of the toilet 11 allows the wheeled commode chair to rotate backwards on the toilet, with the user facing Normal direction away from the wall.

Another particular advantage is that the set of handrails 69 mounted to form the upper part of each spaced apart parallel side frame 21, 22 also perform an auxiliary function. The armrest 69 is cantilevered and extends forwardly along spaced parallel sides and terminates at the front handle 64 . These handles 64 allow the caregiver to be positioned in front of the commode chair while the user sits on the toilet seat 17 on the commode chair, and allow the caregiver to pass through the rear of the alignment large rear channel 35 and serve as a bridge through the toilet. The external cross member structure 55 is used to rotate the commode chair 11 above the toilet.

Dual purpose as commode chair and wheelchair

The heavy part of one embodiment of the present invention is that it is also a wheelchair when it is a commode chair.

Another element that assists in this process is a set of handles 69 extending from the frame 15 including the seat back 61 towards the front of the commode chair 64 . Thus, the user can push the commode chair onto the toilet from the front of the commode chair with the assistance of an assistant. Among other uses of the wheelchair, these handles 64 can double as armrests.

Easily steer and use as a wheelchair with the large support wheels and front wheelchair-style casters.

Use as a commode chair is very advantageous because the caregiver can approach the user at any time from all angles of the commode chair. Furthermore, clean lines and a minimalist structure allow for clean and hygienic convenience for the user, while remaining functional and giving the user a sense of dignity.

Foldability and portability in the folded position

It has been shown that the structure of the commode chair 11 has significant structural advantages for the user in the deployed configuration. However, the foldability of the commode chair 11 has other benefits.

The two side frames 21 , 22 are mounted on respective large side wheels 18 and small front balancing and steering castors 19 and are supported in a similar manner in folded form as shown in FIGS. 9 and 10 . This means the commode chair is easy to transport.

Even if the commode chair is not a wheelchair, the side frames 21, 22 will be supported by the same legs to support the side frames in the unfolded use configuration.

Figures 7 and 8 illustrate how the wheeled commode chair can be transformed from the deployed configuration of Figures 1 , 2 and 3 to the folded configuration of Figure 10 . In particular, FIG. 7 shows the removal of the locking backrest 61 fitted on the respective upright 62 , 63 on the respective side frame 21 , 22 . In use, the backrest provides the service of the backrest to the user, and a means for the caregiver to assist the user by pushing the chair from behind. However, the backrest has a rigid inverted U-shaped frame with a fixed length, and the backrest is achieved by comfortably flexible slats that extend across the frame. When the rigid fixed length frames are inserted into the respective uprights 62, 63, the respective side frames 21, 22 are kept at a fixed distance from each other.

With the backrest 61 removed, the respective side frames are held apart by the hingedly connected first cross-arm member 51 and second cross-arm member 55 . These cross-arm members have support rods extending between them in the Y and Z directions, while the vertically extending second cross-arm member 51 forming a generally X-shaped configuration when held in the deployed position provides rigidity in the X and Y directions. Thus, the structure is three-dimensionally rigid when in the locked position.

As shown in FIG. 8 , by simultaneously unlocking the vertically extending front X-shaped cross member 51 and the rear straight hinged rear cross member 55 to release from the locked condition, the side frames 21 , 22 can be moved closer together for storage. Armrests 69 with front extension handles 64 can be used to turn the folded chair around.

Adjustability for different users

Obviously, the commode chair is multifunctional and can be used by a wide range of users. In particular the commode chair can be modified for use by amputees. This is important in the wheeled version since most of the user's weight is over the large side support wheels 18 . However, it needs to be balanced so that the user's center of gravity is slightly biased towards the diameter of the main wheel 18 and tilted slightly towards the smaller front directional castor 19 . This will prevent the commode chair from tipping over backwards, while allowing the commode chair to turn quickly since the front casters won't carry as much weight.

However, with amputees, the weight of the user's legs is not there, so the center of gravity of the amputee sitting on the toilet chair will be more rearward, because the toilet chair also includes "axle reverse amputee". )", which points to the bracket supporting the axle which can be adjusted so that the center of gravity is adjustable 80-90 mm behind the normal position.

Additional adjustability for different users applies to one or more of the following:

• The seat frame or side frame may include notched portions for cleaning etc.

• The seat frame does not have to be removed in order to fold the commode chair.

·The height of the armrest is adjustable.

• Oscillating footrests, wherein the footrests are adapted to receive the user's feet and are adjustable to swing to allow the user's feet to make contact with the ground.

Other variations are possible.
