Wiuton Ave., La Puente, Calif. Filed Sept. 13, 1965, Ser. No. 486,955 7 Claims. (Cl. 297-118) The present invention relates generally to bath accessories particularly useful for invalids, handicapped persons, or children; more particularly, the invention relates to a com bination bath chair and shower stool which is convertible from the one form to the other, and which includes a foot platform as part of the shower stool.

Invalids, handicapped persons and children often require special assistance for bathing or showering, especially persons who must partake of such ablutions in the sitting position.

The present invention contemplates a novel collapsible seating aid which in one of its forms is a bath chair and which may be converted to a bath or shower stool by the arrangement of its movable interfitting and slidable parts. As a chair, the invention incorporates a back, a

' seat, arm rests and strapping aids in the form of belt and buckle assemblies. The :back is articulatable on the arm rest supports. The seat is slidable in and out of its frame. The arm rests are movable and adjust with and with respectto the back so as to provide a variety of back-to-seat angles for upright or reclining use. The arm rest supports are provided with appropriate stops for any particular upright or reclining position to secure the arm rests in place at the desired back-to-seat angle.

When fully articulated forward, the back is level with the arm rests to form a continuous surface therewith raised above the floor level (at the bottom of the bath or shower), making it useful thus as a stool. The slidable seat may be moved forward in its guides to fonrn a foot pad, when the article in its collapsed form is used as a stool.

It is therefore an object of the present invention to provide a bath chair which is convertible to a bath or shower stool.

An object of the invention is the provision of a bath chair, the back of which is articulatable with respect to the arm rests thereof to form a stool.

It is an object of this invention to provide a combination or convertible bath chair and shower stool wherein a foot platform is provided in the shower stool form thereof.

An object of this invention is to provide a bath chair adapted to rest upon the bottom and against the rear of a bath tub and provided with suction cup feet to prevent slipping.

It is an object of the invention to provide a bath chair wherein the back is articulatable to provide a series of different back-to-seat angles for upright or reclining sitting, and which back when fully articulated forward is aligned with the arm rests of the chair to form a stool without a back.

Another object of the invention is to provide a convertible seat and stool device to accommodate a person in the sitting position while showering or bathing.

It is another object of this invention to provide a combination bath and shower seating arrangement for the safe bathing or showering by an invalid, a handicapped person or a child.

Other objects, features and advantages of the present invention will become apparent to those versed in the art from a consideration of the following description, the appended claims and the accompanying drawings, where- FIGURE 1 is a perspective view of the combination bath chair and shower stool according to the present invention in its fully erected form;

FIGURE 2 is a fragmentary sectional view taken at line 2-2 of FIGURE 1;

FIGURE 3 is a side elevational view of the combination chair and stool of FIGURE 1, illustrating in phantom outline certain positions of components;

FIGURE 4 is a sectional view taken at line 4-4 of FIGURE 3;

FIGURE 5 is a perspective view of the combination chair and stool of FIGURES 1 to 4, showing it in its configuration for use as a stool and foot rest;

FIGURE 6 is a top plan view taken at line 66 in FIGURE 3;

FIGURE 7 is a fragmentary view, partially in section, taken at line 77 in FIGURE 5; and

FIGURE 8 is a rear view of the combination chair and stool when in the configuration shown in FIGURES 1 and 3.

Referring to the drawings, the cornbination chair and stool 5 of this invention generally comprises a seat back 11 with a seat 14 slidable in a frame support 6 of generally U-shaped construction. Frame 6 is open to the front 7 of the chair 5. Channels as may be seen at 28 (FIGURE 5) are provided in frame 6 to permit the sliding of seat 14 forward. Seat 14 has a support foot 14a depending therefrom at the front center thereof so that when seat 14 slides forward it is raised from the floor and maintained level,

Seat back 11 as may be seen in FIGURES 1 and 4 is attached on pivots 34 to and between

arms

12 and 13 so as to be articulatable thereon. Depending from back 11 are

support links

35, 36 which are slidable in guide grooves 37 in the rear portions of arm supports 15 (FIG- URE 2) and which articulate on pivots 38 at the point of dependence of

links

35, 36 from back 11.

Links

35, 36 have

pins

35a, 36a to hold the ends thereof in grooves 37 in arm supports 15. Arm supports 15 are upright tubular inverted U-shaped members attached to the side portions 6a and 6b of frame 6. On each end of arm supports 15 are provided suction cup floor pods 39 so that when the chair or stool 5 is placed on the floor of a tub or shower stall the holding action of suction cup pods 39 will prevent slippage thereof.

At the bottom rear of back 11 a bar 30 is attached thereto. This provides for putting the back 11 over into the seat position and a back rest in the latter position. The bar 30 permits adjustment of back 11 from a straightup to a reclining position, or to the final seat position.

A belt and

buckle arrangement

16, 18 is attached to the seat back 11 as may be seen at 43 in FIGURE 4.

Belt

16, 18 may be secured about the waist of the user when the invention is used as a chair as shown in the FIG- URES 1 and 2. Or when the invention is in the stool configuration shown in FIGURE 5 the belt and

buckle assembly

16, 18 may be secured about the thighs of the person seated on the rear 11b of the back 11 as may be clearly seen in FIGURE 5.

Arm supports 15 have a series of apertures or receptacles 20-24 (FIGURES 1 and 4) on the top surfaces thereof which engage with tongue or

ball extensions

22, 23 in

arms

12, 13 to lock back 11 at one of several angles with respect to seat 11 when the invention is used in the chair configuration thereof. In the inner sides of arms 12 and 13 a pair of

notches

32, 33 are provided which mate with and receive

snap extensions

19, 21 on the sides of back 11 when the back is positioned between

arms

12 and 13 as shown in FIGURE 5 to form a stool seat.

In the light of the above description it may be seen that the operation of the chair 5 and its construction provide 3 an easy means of con version thereof from a bath chair with an adjustable back to a shower stool.

As may be seen in FIGURES l, 3 and 5, the bath chair comprises a rectangular U frame 6 wherein the uprights of the U 611 and 6b have grooves such as 28 in juxtaposed edges thereof (FIGURE 2) which slidably receive a chair seat 14. Inverted U-shaped arm supports 15 are securely and rigidly attached to the uprights of the U- frame 6 and have suction cup pods 39 on the ends thereof. On'the cross bar of the arm rest Us (15) are apertures or receptacles I 20, 24 which engage corresponding pairs of balls or

tongues

22, 23 in the bottom of arm rests 12 and 13' to permit back 11 to be set at different angles. Arm rests 12 and 13 attach to pivots 34 on back 11 to provide articulation of back 11 thereon.

Arms

12, 13 move forward when back 11 is closed to the seat position as is shown by arrows 40 in FIGURE 6.

Belt and buckle assembly 16-18 attached to back 11 provide for securing the individual in the seat by his waist. 1

When the chair is placed in a tub or shower stall suction cups 39prevent slippage.

Y Back bar 30 connected at the bottomrear of back 11 permits lifting and forward motion of back 11 to set it into thesdesi'red position. Within the range of

setting balls

22, 23 in

apertures

20, 24 the back 11 may be set selectively to several positions from an upright to a reclining angle thereof with respect to seat 14.

.ForHuse as a stool as shown in FIGURE the steps suggested in FIGURES 3 and 6 are taken in the following manner:

.Back 11 is moved forward by grasping bar 30 and articulating back 11 on pivots 34.

Links

35, 36 ride up in guide grooves 37 and seat'14 is pulled forward in grooves 28 of frame 6, the knobs 41 engaging groove 28 (FIGURE 7);-. Back 11 finally comes to rest flush with

arms

12 and 13 being stopped by the engagement of knobs or

tongues

19, 21 in receptacles or

notches

32, 33 therein. Seat 14, its support foot 14a resting on the floor surface, now becomes a foot pad and the rear 11b of back 11 becomes the seat portion of a stool. Suction cup pods 39-remain' as slippage prevention means as before.
