United States Patent U.S. Cl. 4-134 Claims ABSTRACT OF THE DISCLOSURE A chair construction adapted to serve a dual function as an occasional room chair as well as a toilet chair. The chair includes a frame which is movable on wheels or casters and a toilet seat is mounted on the frame and is normally covered by a removable seat cushion. By removing the cushion, the toilet seat is exposed and the chair can be moved into position above a toilet bowl or water closet. A foot rest is hinged to the frame and when the chair is used as an occasional room chair, the foot rest is supported under the toilet seat and locked in this position by a latch which is connected to the seat cushion and extends through the opening in the toilet seat.
BACKGROUND OF THE INVENTION This invention relates to a chair construction and more particularly to a chair adapted to serve a dual function as an occasional room chair, as well as a toilet chair.
For non-ambulatory patients in hospitals or rest homes, commodes or toilet chairs are frequently utilized. The conventional commode includes a toilet seat and in some instances a removable bed pan is positioned beneath the seat. Not only is a toilet chair of this type unsightly, but the bed pan requires periodic cleaning and the odor is often objectionable. Other types of toilet chairs used in the past have been movable to a position above a toilet bowl or water closet. While toilet chairs of this type eliminate the problem associated with a bed pan, the conventional toilet chair is a rather unsightly item of furniture and is not normally usable as a room chair.
SUMMARY OF THE INVENTION The present invention is directed to a chair construction which has a dual function in that the chair functions as an attractive occasional chair and can be readily converted to a toilet chair to be moved over a toilet bowl. The chair of the invention includes a frame having a series of legs supported on wheels or casters so that the chair can be readily moved over the floor. A toilet seat is mounted on the frame and is normally covered by a removable seat cushion. By removing the seat cushion, the toilet seat is exposed and the chair can be moved to a position above a toilet bowl.
The chair of the invention also includes a novel foot rest structure in which the foot rest is hinged to the frame and when the chair is used as a toilet chair the foot rest will be in an operative position to support the feet of the patient. When the chair is to be used as an occasional chair, the foot rest is pivoted upwardly to a position beneath the toilet seat and locked in this position by a latch which is connected to the seat cushion and extends through the opening in the toilet seat. With the foot rest locked in its inoperative position and with the seat cushion in place, the unit appears to be a normal occasional chair without any visual evidence of the foot rest or toilet seat.
The chair can be readily converted to a toilet chair by merely removing the seat cushion, thereby exposing the toilet seat and automatically causing the foot rest to be unlatched. The foot rest will pivot by gravity to a position where it will support the feet of the patient. With the patient sitting in the chair the chair can be moved to a position above the toilet bowl.
The chair of the invention is of simple construction having few moving parts and not only provides a decorative room chair but is readily converted to a toilet chair. The chair eliminates the problems normally associated with a bed pan, as used in the past in commode chairs or the like,
Other objects and advantages will appear in the course of the following description.
The drawings illustrate the best mode presently contemplated of carrying out the invention,
In the drawings:
FIG. 1 is a perspective view of the chair of the invention as used as an occasional room chair;
FIG. 2 is a perspective view showing the chair being used as a toilet chair and located above a toilet bowl;
FIG. 3 is a side elevation of the chair with parts broken away showing the foot rest in the upper locked position; and
FIG. 4 is an enlarged fragmentary view showing the latching arrangement.
The drawings illustrate a chair construction which serves a dual purpose as an occasional room chair, as well as a toilet chair. The chair 1 includes a series of legs 2 which are supported on casters or wheels 3, thereby enabling the chair to be readily moved over the floor. The legs 2 are connected togeter by front cross member 4 and a rear cross member 5, as well as a pair of side members 6 and 7. The legs 2, as well as the members, 4, 5, 6 and 7 provide a frame for the chair. *The upper ends of the legs 2 are connected together by U-shaped frame member 8 which supports a pair of arm rests 9. A back plate 10 is connected to the frame member 8 and a back cushion 11 is mounted on the plate 10.
According to the invention, a generally-flat pan 12, made of aluminum, stainless steel or plastic material, is mounted on the frame and is connected to the cross members 4 and 5, as well as the side members 6 and 7 by bolts which extend through aligned openings in the frame members, as well as through the pan 12. The central portion of the pan 12 is provided with an opening 14 and a toilet seat 15 is hinged to the pan by hinge 16 and is similarly provided with an opening which registers with the opening 14 in the pan 12 when the toilet seat is in the lowered position.
As shown in FIG. 1, when the chair is used as an occasional room chair a removable seat cushion 17 is supported on the frame and covers the toilet seat 15. The bottom surface 18 of the seat cushion rests on the frame members 4, 5, 6 and 7 and the forward edge of the seat cushion is provided with a pair of U-shaped brackets 19 which straddle the front cross member 4 and thereby position or align the cushion with respect to the pan 12.
The chair of the invention also includes a foot rest 20 which is adapted to be moved between an operative position, as shown in FIG. 2, in which the foot rest is in a position to support the feet of the patient, and an inoperative position in which the foot rest is locked beneath the undersurface of the pan 12, as best illustrated in FIGS. 3 and 4.
The foot rest 20 is supported by a pair of arms 21 which are pivotally connected to the ends of supports 22. The upper ends of the support 22 are pivotally connected to the outer surfaces of the side members '6 and 7, respectively, by pins 23.
The pivotal connection between the arms 21 and sup ports 22 is such that the arms 21 can be pivoted from a position normal to the supports 22, as shown in FIG. 2, to a folded position in which the arms 21 and foot rest 20 are generally parallel to the undersurface of pan 12, as illustrated in FIG. 3. Suitable stops are employed so that the arms 21 will be maintained at an angle of about 90 with respect to the supports 22 when the foot rest is in the operative position, as shown in FIG. 2.
The foot rest is prevented from moving forwardly, when in the operative position, by virtue of the location of the pivotal connection of supports 22 with the side members 6 and 7. This connection is immediately to the rear of the front cross member 4 so that the front cross member will serve as a stop and limit forward movement of the supports 22. The support members 22 are prevented from moving rearwardly, when the foot rest 20 is in the operative position, by a latch member 24 which is pivotally connected to one of the legs 2 by bolt 25. By pivoting the latch member 24 from a position parallel to the leg to a locking position normal to the leg, the end of the latch 24 will engage one of the supports 22 to prevent rearward movement of the support and foot rest. Thus, the foot rest is locked against both forward and rearward movement when it is in the down or operative position.
A latching mechanism associated with the seat cushion 17 is utilized to hold the foot rest in the upper or storage position. The latching mechanism includes a catch 27 which is connected to the undersurface 18 of the seat cushion by a pair of screws. The catch is provided with an outer tapered tip 28 and a central neck 29. The catch 27 extends downwardly through the aligned openings in the toilet seat and pan 12 and is adapted to be received within a hole 30 formed in the foot rest 20, to hold or lock the foot rest 20- in the storage position.
To move the foot rest 20 to the storage position, the supports 22 are pivoted rearwardly to a position where they are in general alignment with the side members 6 and 7. The arms 21 are then pivoted with respect to the supports 22 moving the foot rest 20 to a position substantially parallel with the bottom 18 of the seat cushion. By holding down on the seat cushion and pushing upwardly on the foot rest the tip 28 of the catch 27 will be forced through the hole so that the hole is engaged with the neck 29 of the catch, as illustrated in FIG. 4, to maintain the foot rest in the upper storage position. This latching mechanism serves a dual function in that it not only holds the foot rest in the storage position where it is not generally visible but also serves to hold the rear edge of the cushion downwardly so that a person sitting on the front edge of the cushion will not tend to tilt the rear of the cushion upwardly.
The latching mechanism for the foot rest is automatically released by removing the seat cushion. By moving the seat cushion 17 upwardly the catch 27 is disengaged from the opening 30 in the foot rest and the foot rest will then pivot downwardly by gravity to the operative position.
While the above description illustrates the toilet seat 15 being hinged to the pan 12 it is contemplated that the seat 15 and pan 12 may be molded or otherwise formed as an integeral unit.
Suitable locks can be associated with the casters 3 to lock the casters and prevent movement of the chair when it is in a osition a ove the toilet bowl.
As illustrated in FIG. 1, the chair with the seat cushion 17 in position and the foot rest 20 in its storage position is an attractive occasional chair without the physical appearance of the conventional toilet or commode chair. The chair can be readily converted to a toilet chair by simply removing the seat cushion from the toilet seat and this releases the latching mechanism so that the foot rest 20 will drop into the operative position. The foot rest is then locked in position by pivoting the latch 24 to the cross position. With the patient then seated in the chair the chair can be moved into a position over the toilet bowl as illustrated in FIG. 2. After use as a toilet chair, the chair is converted to its normal appearance by positioning the seat cushion 17 on the pan 12 and manually pivoting the foot rest 20 to the upper position while holding down on the seat cushion thereby causing the catch 27 to engage within the hole 30 of the foot rest to lock the foot rest in the storage position as well as locking the rear portion of the cushion against upward movement.
