10 Claims.

The present invention relates to toilet seats and more particularly to auxiliary toilet seats adapted for use by small childrfln.

An object of the invention is to provide a childs toilet seat which adapted for attachment to an adult toilet seat, and which is compactly fcldable to a position adjacent to the 1111-. derside of the cover member, so as to permit nor.- mal use of the adult toilet seat.

Another object is to provide a child's toilet seat which can be mounted in a simple manner and which is capable of easy folding and um folding.

A further object is to perfect details of construction generally.

The invention further consists in the several features hereinafter described and claimed.

In the drawings, designates a conventional .closet bowl on which is mounted a conventional hinged toilet seat, the latter comprising a seat member 21 and a cover member 22 provided at their rear portions with hinge members 23 which are pivotally connected by pintles 24 to upstand ins bracket bolts 25 rigidly secured to the bowl. The seat member 2i, which is designed for adult use, consists of the usua1 rim with a rounded upper surface, and is here shown to be of the closedfront type, although an open-front seat member of conventional type may be used instead.

In accordance with the invention, an auxiliary or child's toilet seat, designated generally by the number 26, is associated with the adult seat and includes a dished seat member 21 of generally oval shape which detachably nests into the adult seat member 2|, the auxiliary seat member having a concave bottom surface 28 to fit the rounded surface of the adult seat member. A back rest or plate 29 is connected by a spring hinge 30 to the rear end of the auxiliary seat member 21, the hinge having a coiled torsion spring 3!, Figs. 2 and '6, tending to move the auxiliary seat memher and back rest angularly apart. The marginal portions 32 of the back rest are offset rearwardly. A pair of side plates 33 are co nected by hinges 34 to the opposite side portions of the auxiliary seat member 21, and are swingable upwardly to parallel vertical positions, as seen in Figs. 1, 2, 4, and 5. The side plates are shaped to fold inwardly about parallel hinge axes to a nested position within the dished auxiliary seat member, as indicated in Figs. 6 and '7, and in this position the hinged back rest is foldable over the side plates and nests into the folded side plates. The auxiliary seat member, back rest and side plates are preferably formed wholly or mainly f a hardened plastic material such as Bakelite. The

back rest and side plates are connected by fiat brace bars 35 each of which at one end is hinged at 36 to a bracket or car 31 swiveled at 38 to t it?v marginal portion of the back; rest, and which at the other end is hinged at 3,9 to a bracket or ear 40 swiveled at M to the upper edge portion of the associated side plate. In the folded posi-. tion of the parts the flat brace bars 35 are interposed between the side plates and the back r s as se is Fi the ide plates havin marginal notches 42 at their dished edges and recesses 43 at their upper edges to accommodate the brace bars. The side plates, when in their upstanding position, have their front portions connected by a metal cross strap comprising complementary

flat bars

44 and 45 each of which is hinged at 46 at its outer end to a bracket or ear 4'! swiveled at 48 on the outer side of the associated side. plate, there being a recess 49 in the side plate to accommodate the ear. The cross bar 44 has spaced end knuckles 50 carrying a cross pin 5i detachably engageable by a, terminal hook 52 on the bar 45, and the two cross bars are held down in aligned position by coiled torsion springs 53 on the respective hinges of the bars. In. the folded condition of the auxiliary seat the swiveled cross bars extend in rabbets 54 formed along the outer sides of the side plates and are held therein by the torsion springs 53.

In some instances, the auxiliary seat member 21 is provided at its upper front portion with a deflector plate 55 which is hinged at 56 at its rear edge and is frictionally retained in position, the deflector plate being bent to conform to the contour of'the seat member.

The back rest 23 is connected by a link 51 with a mounting plate 58 which is adapted to be secured to the underside of the cover member 22 of the adult seat, the link having a hinge connection 59 with the back rest and a hinge connection 63 with the mounting plate, the axes of the hinge connections being parallel with the axis of the hinge pintles 24. The hinge connection Bil is provided with one or more torsion springs 6| tending to urge the back rest away from the mounting plate. In the unfolded position of the auxiliary seat, seen in Fig. 1, the back rest 29 is approximately parallel to the cover member 22. The mounting plate 58 has a rim or bead 82 adapted to conceal the edge portions of the auxiliary seat when the latter is folded, the rim or bead being preferably formed mainly of a hardened plastic material. If desired, the mounting plate may be attached to the cover member by screws, not shown, slots 63 being provided in the plate for this purpose. The mounting plate is here shown to be adjustably secured to the cover member by pairs of hook members 64 engaging opposite side edges of the cover member. Each hook member bears on the mounting plate and is guided by a stud 65 which is secured to the plate and extends in a slot 66 in the hook member. A pair of levers 61 are pivotally secured at 68 to each side of the mounting plate and bear on the respective hook members, the hook members and levers having cooperating roughened clamping surfaces 69 and 10. The pair of levers are confined by a cover plate H which is secured to the mounting plate 53 and is disposed in a recessed part of the rim 62. Each cover plate has detents 12 to engage recessed parts of the levers when the latter are in their closed position. The cover plate also has a notch 72' at its inner edge to facilitate outward displacement of the levers. If desired, the rim may be provided with inset rubber bumpers 13.

The front end of the rim or bead 32 carries retaining means, Figs. 9 and 12, to hold the folded auxiliary seat within the rim. The retaining means is here shown to include a suitably guided forwardly projecting push slide 14 which is urged outwardly by an arched leaf spring 15. A pair of fingers it are pivoted at H in the rim and have inwardly projecting end portions 18 to engage the front edges of the auxiliary seat member 21.

to the mounting plate 58 to engage the rear por-' tion of the folded auxiliary seat member, the back rest 29 being suitably apertured to pass this finger.

To install the auxiliary toilet seat 26 on the adult toilet seat, the former is folded flat and rested on the adult seat member 2! to nest therein, the levers 61 being swung outwardly. The cover member 22 is then lowered onto the mountingplate 58, and the hook members 64 are then pushed inwardly against the edges of the cover member. The locking levers 6'! are then pushed inwardly to their locked inner positions, causing the hook members to grip the opposite side edges of the cover member. The assembly is then ready for use. When it is desired to transfer the auxiliary seat to another toilet seat, the auxiliary seat can be readily detached by swinging out the locking levers 31. The auxiliary seat can be installed without the use of tools and without marring theadult seat.

When the conventional toilet seat is to be used by an adult, the auxiliary seat is folded and latched on the mounting plate, as seen in Figs. 3, 6, and 7, whereupon the auxiliary seat will swing as a unit with the cover member 22. When the auxiliary seat is to be used, it is unlatched from the mounting plate preferably while the cover member is in its horizontal position, shown in Fig. 7, whereupon the cover member is raised to the approximately vertical position shown in Figs. 1 and 2, causing the auxiliary seat to unfold. In this operation, the spring hinges 33 and 60 tend to open the linkage and keep the auxiliary seat member 2! nested in the main seat member 2|. After the child is seated on the seat member 27!, the cross straps 44 and 45 are swung inwardly from the side plates 33 and are joined by the hook connection 5|, 52, thus preventing the child from falling. The auxiliary seat member 21 is here shown to have a closed front, but insome cases this seat member may have an open front.
