DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 1 and 2, the assembled perspective view and exploded perspective view of the preferred embodiment about the multi-functional wheel chair of the present invention are illustrated. The multi-functional wheel chair according to the present invention includes a chair seat 1, a chair frame 2, two hand supports 3, and a back rod 4. The chair seat 1 has a chair seat body 10 which has an approximate concave shape, and a front side thereof is formed with an opening 11. The opening extended backwards to a proper distance. The bottom of the chair seat body 10 is installed with sliding tracks 12 at a left and a right side of the opening 11 so that an excreta collector can be inserted from a rear side (see FIG. 5). A plurality of draining holes 13 are formed near an edge of the chair seat body 10 so that water on the top of the chair seat body 10 can be drained out from the draining holes 13 and thus water is not accumulated on the top of the chair seat body 10. One side of the chair seat body 10 is pivotally installed with a shower nozzle frame 14. As the shower nozzle frame 14 does not been used, it can be place horizontally, while as it is used then it is upright or placed vertically (see FIG. 6) so as to be pushed aside of the shower nozzle 6 for hanging the shower nozzle 6 for cleaning. A movable shower nozzle water box can be used. One side of the chair seat body 10 is firmly secured with a sleeve 15 for being inserted by a drip frame 7 (see FIG. 7) for hanging with a drip bottle 70. The drip bottle can be adjusted upwards or downwards and then is locked by a fixing button 45 screwedly connected to sleeve 15.

The chair frame 2 is made of metal tubes and is installed below the chair seat 1. The chair frame 2 includes four chair legs 20. An upper end of each leg 20 is properly connected to a bottom of the chair seat 1. The lower end of each of two chair legs 20 is pivotally installed with a front wheel 21, while the lower end of each of two chair legs 20 is pivotally installed with a rear wheel 22. By the rolling of the front wheels 21 and the rear wheel 22, the wheel chair may move convenient, moreover, the front wheel 21 may rotate for rotating the wheel chair. Each of the front chair legs 20 is installed with a pedal 23 for placing the leg of the user. The pedal 23 is pivotally installed to a connecting rod 24. Another end of the connecting rod 24 covers on the front chair legs 20 by a cover 25 so that the pedals 23 may turn upwards or downwards through 90 degrees or leftwards and rightwards through 90 degrees.

The hand supports 3 are placed at the left and right sides of the chair seat 1. Each of the hand support 3 has a support body 30 having an approximate L shape, which has the functions of supporting the hands and backs of the user. The surface of the hand supports is enclosed d by soft sponge 31. The support body 30 has a rear side installed with a handle 32 for pushing the wheel chair. The bottom of the support body 30 is connected to a support frame 33. The support frame 33 is telescopic and is formed by engaging an inner tube 34 with an outer tube 35. The support body 30 is connected to an upper end of the inner tube 34. The lower end of the outer tube 35 is connected to the left and right sides of the chair seat 1. The inner tube 34 and outer tube 35 are telescopically for adjusting the length so that the support body 30 can be adjusted upwards or downwards (see FIG. 8), and then a fixing button 36 screwedly connected to an upper end of the outer tube 35 serves to lock it.

A lower end of the support frame 33 is connected to the left and right sides of the chair seat 1 through a first joint device 37 (see FIG. 3). The joint device 37 includes second ratchets 371 at a lower end of the support frame 33 and second ratchets 372 at the left and right sides of the chair seat 1. The first ratchet 371 and second ratchet 372 are engageable and a pivotal element serves to pivotally connect the first ratchet 371 with the second ratchet 372, and then is screwedly to a fixing button 374. The support body 30 can rotate through 360 degrees around the fulcrum of the pivotal element 373 for adjustment (see FIG. 8). By the engagement of the ratchets 371 and 372, the object of a multi-stage positioning and adjustment is achieved. After adjusting, by tightly screwing the fixing button 374, the orientation of the support body 30 can be fixed. The left and right hand supports 3 can be adjusted in orientation and longitudinally so as to clean the left side and right side of the user conveniently.

The back rod 4 is installed at a front side of the chair seat 1, and includes a rod body 40 which is a horizontal body. The bottom of the rod body 40 is connected to supporting frame 41. The supporting frame 41 is telescopic and is formed by an inner tube 42 and an outer tube 43. The back rod body 40 is connected to an upper end of the inner tube 42. The lower end of the outer tube 43 is connected to a transverse rod 44 installed at the front two chair legs 20. The inner tube 42 and the outer tube 43 may adjust the length telescopically so that the supporter body 40 are adjusted upwards or downwards (see FIG. 8). Then a fixing button 45 screwedly connected to an upper end of the outer tube 43 serves to lock it.

The lower end of the supporting frame 41 is connected to the transverse rod 44 of the front two chair legs 20 by a second joint device 46 (see FIG. 4). The joint device 46 has two third ratchets 461 installed at the lower end of the supporting frame 41 and two fourth ratchets 462 installed at the transverse rod 44. The two ratchets 461 and 462 are engaged with one another so that the rod body 40 may be adjusted upwards or downwards (see FIG. 8). Therefore, an effect of multiple stage adjustment is achieved.

Referring to FIG. 9, in the present invention, a front side of the chair seat 1 is installed with a back rod 4. The user may be adhered to the rod body 40 of the back rod 4 for cleaning the back. Furthermore, referring to the FIG. 10, a movable head washing frame 8 may be installed on the two hand supporters 30 and the handle 32 for being pushed to a washing basin for washing head. Moreover, referring to FIG. 11, in the present invention, the wheel chair can be moved to be near a commode for cleaning and going to stool.

Therefore, in the defects of prior art, such as inconvenience of washing back, head and going to stool, the hand supporters and back supporters are fixed and adjustment, are improved by the present invention.

Although the present invention has been described with reference to the preferred embodiments, it will be understood that the invention is not limited to the details described thereof. Various substitutions and modifications have been suggested in the foregoing description, and others will occur to those of ordinary skill in the art. Therefore, all such substitutions and modifications are intended to be embraced within the scope of the invention as defined in the appended claims.
