Claims. (CI. 4—134)

My invention has for its object a folding nursing chair incorporating a chamber pot, the novelty of which consists in that it includes in combination a folding support and ιθ an interchangeable container adapted to be fitted over said support and made of a simple sheet of plastic material.

More specifically, my invention has for its object a folding chamber pot comprising a seat to the underside of which are pivotally secured at least two feet adapted 15 to be folded and to which is pivotally secured a flap forming a movable seat including, in combination with the former, stationary seat, means which allow clamping over the opening of the seat, the periphery of a sheet adapted to serve as a removable receiver or container. 20

In accordance with one embodiment of the means securing said sheet to the foldable support constituted by the stationary seat and its feet, said stationary seat carries a number of studs on its upper surface whereas the movable seat is provided in its lower surface with blind holes 25 in which said studs may be fitted with the interposition of the sheet serving as a container so as to hold the latter in position.

The accompanying diagrammatic drawings illustrate by way of example and in a non-limiting sense a preferred 30 embodiment of my invention.

In said drawings:

FIG. 1 is a perspective view in dot-and-dash lines of the sheet serving as a container, in its position of use.

FIG. 2 is a longitudinal vertical sectional view of the 35 chamber pot.

FIGS. 3 and 4 are views of the chamber pot in its collapsed condition respectively as viewed from above and sideways.

The folding support forming part of the chamber pot includes chiefly two seats shown respectively at 2 and at 3 and pivotally connected together through the hinges 4 which allow folding back the upper movable seat 3 over the lower seat 2. To the underside of the lower seat 2 which is to be considered as a stationary seat, are pivot- ⁴⁵ally connected through hinges 5 the feet 6 and 7 located respectively to the front and to the rear of the pot. The front foot 6 is given a generally rectangular or trapezoidal shape, while the rear foot 7 is given the shape of an inverted U adapted to match the outline of the foot 6 ^o0when the feet are both in their collapsed condition.

The stationary seat 2 carries studs or projections 8 registering with blind holes 9 formed in the lower surface of the movable seat 3. When the two seats are in contact, the upper seat 3 being folded over the lower seat 2, ⁰⁰the studs 8 enter the holes 9. The support thus executed is practically flat in its folded condition as illustrated in FIGS. 3 and 4. The two seats 2 and 3 are in fact superposed and the two feet 6 and 7 are folded back over the lower surface of the lower stationary seat 2, the front foot ⁶⁰6 extending inside the outline of the rear foot 7 as illustrated in FIG. 3. The folding support is advantageously associated with a small-sized back 10 including an arm 12 of which the lower end is adapted to engage removably an opening 13 formed in the rear portion of the movable seat 3.

When using the chamber pot, the folding support described is associated with a sheet of plastic material 14 the periphery of which is clamped as illustrated in FIGS. 1 and 2 between the two seats, the studs 8 on the seat 2 entering the holes 9 of the seat 3 with the interposition of the sheet 14. The latter which is thus suspended through its periphery to the seats 2 and 3 forms the container which may be cast away after use.

When not in use, my folding chamber pot may advantageously be carried inside a small bag which may carry furthermore a bundle of sheets of plastic material adapted to form as many containers, each adapted to be used only once.
