7 Claims.- (Cl. 4-239) The present invention relates generally to auxiliary toilet seats for use by children. More particularly the invention relates to that type of auxiliary toilet seat which is adapted to be associated with a regular toilet seat for use by adults and as its parts or components comprises: (1) a base which has a centrally positioned aperture therein, is shaped substantially conformably to, but is of slightly less size than, the regular seat and has hinge means at its rear portion whereby it may be swung back and forth between an operative position wherein it overlies, and is supported on, the regular seat and an inoperative position wherein it extends upwards and rearwards and exposes the regular seat so that it is capable of use; (2) a back which extends across the back portion of the base and is hinged thereto so that it is capable of swinging up and down; (3) a pair of sides which are hinged to the side portions of the base to swing up and down and are adapted when they and the back are in their up position to form with the back a U-shaped wall structure for holding in place the child using the auxiliary seat; (4) a detachable crossbar which is adapted when the sides are in their up position to extend between the front distal corners of the sides and hold the sides in place; and (5) a plate which is hinged to the front portion of the base to swing up and down and serves when in its up position to form a baffle or deflector.

One object of the invention is to provide an auxiliary toilet seat which is an improvement upon, and has certain inherent advantages over, previously designed auxiliary seats of the same general type and is characterized by simplicity of design and low cost of manufacture.

Another object of the invention is to provide an auxiliary toilet seat of the type under consideration in which the hinged back is adapted when in its down position to overlie the back portion of the centrally apertured base and has at its ends hinged wings which are adapted when k the back is in its down position to extend outwards and rest on the subjacent portions of the base and are further adapted when the back is swung into its up position to be swung rearwards into a position wherein they extend at substantially right angles to the back and form braces for preventing rearward displacement of the back when the latter is subjected to a rearward force in connection with use of the auxiliary toilet seat.

Another object of the invention is to provide an auxiliary toilet seat of the last mentioned character in which the hinged wings at the ends of the back are provided at their inner or proximal side margins with rigid coplanar lugs which when the wings are swung rearwards into their operative position after upward swinging of the back extend forwards and form stops for limiting outward swinging movement of the sides when the latter are in their up position.

Another object of the invention is to provide a childs auxiliary toilet seat of the aforementioned type in which the sides are hinged to the side portions of the base in- Wards 0f the outer edges of such side portions, are adapted when in their down position to cover substantially all of the centrally disposed aperture in the base and have in their front distal corners cutouts which when the sides and the'baflie plate are in their down position accommodate one end portion of the batfle plate.

Another object of the invention is to provide an auxiliary toilet seat of the type under consideration in which one end of the crossbar is connectable to the front distal corner of one of the sides by a tongue and slot connection and has at its other end latch means for connecting it to the front distal corner of the other side.

Another object of the invention is to provide a childs auxiliary toilet seat of the type and character under consideration in which the central portion of the crossbar is provided with a downwardly facing groove which is adapted when the crossbar is in its operative position and the baflie plate is in its up position to receive and interlock with the upper end of the baffie plate to the end that the crossbar serves to hold the baflie plate in place.

A further object of the invention is to provide an auxiliary toilet seat of the character under consideration in which the back, sides and baffle plate are so arranged and designed that they lie in a single plane when in their down position and the portions of the base that are outwards of the sides have upwardly extending enlargements, the top surfaces of which lie in such plane to the end that when the auxiliary seat is in what may be termed its collapsed or folded position the entire top of the seat is flat and hence permits the auxiliary seat to form, if so desired, a cover for the regular seat with which it is associated.

A still further object of the invention is to provide a childs auxiliary toilet seat which is generally of new and improved construction and effectively and efliciently fulfills its intended purpose.

Other objects of the invention and the various advantages and characteristics of the present childs auxiliary toilet seat will be apparent from a consideration of the following detailed description.

The auxiliary toilet seat that is shown in the drawings constitutes the preferred form or embodiment of the invention. It is designed for use by extremely young or small children and is adapted to be associated with a regular or conventional toilet seat 9. The latter is adapted for use by adults and is illustrated in the drawings as being associated with, and forming a part of, a standard bowl 10. The bowl has a rim 11 at the top thereof and embodies a rearwardly extending enlargement 12 at the rear portion of the rim. The regular seat 9 has a large sized centrally disposed aperture 13 and is connected by a hinge structure 14 so that it is capable of swinging hack and forth between a normal position wherein it overlies and rests on the rim 11 of the bowl and an inoperative position wherein it extends upwards and rearwards. The hinge 14 is of conventional construction and consists of an inverted U-shaped bracket 15 and a pair of arms 16. The lower ends of the depending end parts of the bracket 15 extend into, and are mounted in fixed relation with, the rearwardly extending enlargement 12 as well understood in the art. The arms 16 are disposed in spaced apart relation and are arranged so that certain ends thereof fit against the rear portion of the bottom surface of the regular seat 9. The other ends of the arms 16 extend rearwards and are provided with eyes 17 which encircle the ends of the intermediate part of the inverted U-shaped bracket 15. The auxiliary seat is of unitary character and normally overlies the regular seat 9. It is of slightly smaller size than the regular seat and consists of a base 18, a back 19, a pair of sides 20, a detachable crossbar 21 and a baffle plate 22. If desired, these parts may be formed of molded plastic material.

The base 18 is shaped substantially conformably to, but is of slightly less size than, the regular seat 9 and has an aperture 23. The latter is formed in the front central portion of the base and is in substantially centered relation with the aperture 13 in the regular seat 9 when the base is in its operative position wherein it overlies and rests on the regular seat. As shown in the drawings the front of the aperture 23 is straight and the remaining portions of such aperture are curved or arcuate. The bottom surface of the base 18 is preferably flat, as shown in the drawings, and the top surface, except for the hereinafter mentioned enlargements is also fiat. The base is provided at its rear portion with hinge means whereby it may be swung back and forth between its aforementioned normal or operative position wherein it overlies and rests on the regular seat and an inoperative position wherein it extends upwards and rearwards and exposes the regular seat so that it is capable of use. The hinge means consists of a pair of elongated hinge brackets 24 which are preferably formed of comparatively heavy metal stampings and extend lengthwise of the base 18. The front ends of the brackets fit against the rear portion of the bottom face of the base and are secured in place by way of vertically extending screws 25. The latter have kerf equipped heads at their lower ends in order that they may be turned into and out of place by way of a screw driver or like tool. The shanks of the screws 25 extend upwards through longitudinal slots 26 in the front ends of the hinge brackets 24 and have the upper ends thereof disposed within screw threaded holes in the rear portion of the base 18. When the screws are loosened the slots 26 permit the base 18 to be adjusted forwards or rearwards in order to bring it into proper relation with the regular seat 9. The rear ends of the hinge brackets 24 are bent to form substantially circular eyes 27 which extend loosely around the intermediate part of the inverted U-shaped bracket 15 and are located inwards of the eyes 17. The free ends of the eyes 27 are provided with forwardly extending extensions which fit against, and are secured by screws 28 to, the portions of the brackets 24 that are directly inwards of the eyes 27. The base 18 of the auxiliary seat is provided at different points with rubber feet 29 which are suitably secured to the bottom surface of the base and are adapted when the base is in its operative position to rest on the regular seat 9.

The back 19 is substantially rectangular and extends transversely across the back portion of the base 18. It is provided at one margin thereof with a pair of spaced apart hinges 30 and these serve to support the back so that it is free to swing back and forth between a down position wherein it fits flatly against the back portion of the upper surface of the base (see Figures 1 and 4) and an up position wherein it extends at substantially right angles to the base (see Figures 2 and 3). As shown in the drawings the hinged margin of the back is disposed a short distance behind the rear portion of the aperturc 23 in the base. The hinges 30 are of conventional construction and comprise fiat plates 31, fiat plates 32 and pintles 33. The plates 31 are disposed in rectangular recesses 34 in the upper surface of the base 18 and are secured in place by screws or other attaching means. The recesses 34 are of such depth that the upper surfaces of the plates 31 are flush with the top surface of the base. The plates 32 of the hinges 30 are disposed in rectangular recesses 35 in the hinged margin of the back 19 and are suitably secured in place. The recesses 35 are of such depth that the outer surfaces of the plates 32 are fiush with the back surface of the back. The pintles 33 extend through eyes on the adjoining side margins of the plates 31 and 32. As shown in Figures 3 and 4, the hinges 30 are so arranged that the back 19 swings rearwards and downwards into its down position and upwards and forwards into its up position. The ends of the back 19 are provided with a pair of wings 36 and these are connected to the end margins of the back by hinges 37 and are adapted when the back is in its down position to extend outwards and rest on the subjacent portions of the base 18. They are further adapted when the back is swung upwards into its up position to be swung rearwards into a position wherein they extend at substantially right angles to the back and form braces for preventing rearward displacement of the back when the latter is subject to rearward force or pressure in connection with use of the auxiliary seat. The hinges 37 are like the hinges 30 and consist of flat plates 38. flat plates 39 and pintles 40. The plates 38 of the hinges 37 are disposed in recesses 41 in the end margins of the back and are secured in place by screws or other suitable means. The plates 39 are disposed in recesses 42 in the inner margins of the wings and are suitably secured in place. The pintles 40 extend through staggered eyes on the adjoining margins of the plates 38 and 39. When the wings 36 are in their operative position, as shown in Figures 2. 3 and 7, the bottom edges thereof rest directly on the sub jacent portions of the base 18. As shown in the last mentioned figures the base of the auxiliary toilet seat is provided with a pair of spaced apart upstanding bosses 43 which serve when the back is in its up position and the wings are swung rearwards into their operative position. to prevent the wings from swinging towards one another. The end margins of the back are provided with sockets 44 for accommodating the bosses 43 when the back is in its down position. As a preliminary to swinging the back into its down position the wings are swung outwards and forwards until they are in coplanar relation with the back. As soon as the wings are in such relation the back is free so that it may be swung rearwards and downwards onto the back portion of the upper surface of the base 18. The outer edge portions of the back and the wings are shaped substantially conformably to the corresponding edge portions of the regular toilet seat 9. The inner margins of the wings 36 are provided with rigid coplanar lugs 45 which when the back and wings are in their operative position project forwards of the back as shown in Figure 2. The end margins of the back 19 have notches 46 for accommodating the lugs 45 when the wings and back are in their down or inoperative position. The purpose of the lugs 45 is set forth in detail hereafter. The back 19 and the Wings 36 are flat and also the same in thickness. As a result of this the top surface of the back and wings are coplanar or flush when the back and wings are in their down or folded position as shown in Figures 1 and 4.

The sides 20 of the auxiliary seat are flat and extend forwards from the back 19. They are disposed in side by side relation and are connected by hinges 47 to the side portions of the base 18. The latter comprise flat plates 48. flat plates 49 and pintles 50 and serve to support the sides 20 so that they are free to swing back and forth between a down position wherein they are coplanar and cover substantially all of the aperture 23 in the base 18 and an up position wherein they extend at right angles to the base and the back 19 and form with the back when the latter is in its up position, a U-shaped wall structure for holding in place the child using the auxiliary seat. The plates 48 of the hinges 47 are disposed in rectangular recesses 51 in the side portions of the base 18 and are secured in place by screws or other attaching means. The plates 49 are disposed in rectangular recesses 52 in the proximal side margins of the sides 20 and are suitably secured in place. The pintles 50 extend through eyes on the adjoining side margins of the plates 48 and 49. The hinges 47 are located inwards of the outer edges of the side portions of the base 18 and are in alignment with the end margins of the back 19 to the end that when the sides are swung upwards into their up position the rear end margins of the sides are located adjacent the end margins of the back. The sides swing inwards and downwards into their down position and upwards and outwards into their up position and are so arranged that the rear end margins thereof abut against the rear end margins of the back 19 when the sides and back are in their up position. When the sides are in their down position the distal side edges thereof abut against one another as shown in Figure 1. When the sides are in their up position while the back is in its up position and the wings 36 are in place the rear end margins of the sides abut against the forwardly extending lugs 45 and such lugs form stops for limiting further outward swinging movement of the sides. The sides are the same in thickness as the back and wings and hence when the sides, back and wings are in their down position their upper surfaces are coplanar or flush. The front distal corners of the sides 20 have cutouts 53 for a purpose to be described hereafter. The front end margins of the sides are curved conformably to the corresponding out edge portions of the base.

The crossbar 21 is adapted to extend between the front distal corners of the sides and serves when in place while the sides are in their up position to hold the sides against inward as well as outward swinging movement. It is of unitary character and comprises a top wall 54, a pair of spaced apart side walls 55 and a pair of end walls 56. The bottom of the crossbar is open as best shown in Figure 8 of the drawings. One end wall of the crossbar 21 is provided with an integral outwardly extending tongue 57 which when the crossbar is in its operative position fits within a slot 58 in the front distal corner of the adjacent side 20 of the auxiliary seat and forms therewith a detachable interlocking connection for holding the one end of the crossbar in connected relation with the front distal corner of said adjoining side. Theother endwall 56 of the crossbar is provided with an integral depending hook 59 and this is adapted when the crossbar is in'its operative position to straddle the outer distal corner of the other side wall of the auxiliary seat. The end of the crossbar that embodies the depending hook 59 is provided with a horizontally elongated enlargement 60 and has latch means 61 for releasably securing it in connected relation with the adjoining side 20 of the auxiliary seat. The enlargement 60 is formed integrally with the adjoining portions of the top and side walls of the crossbar and has a longitudinally extending bore 62, the inner end of which is closed and the outer end of which is open and faces the depending hook 59. The latch means 61 comprises a horizontally extending bolt 63 which is slidably mounted in the outer end of the bore 62. The outer end of the bolt is adapted when the bolt is slid outwards (see Figure 8) and the crossbar 21 is in its operative position, to fit within a slot 64 in the outer distal corner of the adjoining side 20 and operates when in such slot to hold the adjacent end of the crossbar in connected relation with said adjoining side. The inner end of the bolt 61 is provided with a rigid horizontally extending reduced stem 65, the inner end of which is bent downwards, extends through a slot 66 in the inner lower corner of the enlargement 60 and forms a finger piece 67 whereby the bolt 63 may he slid inwards in order to disengage it from the slot 64 when it is desired to remove the crossbar after use of the auxiliary seat. The bolt 63 is urged outwards by means of a spiral compression spring 68. The latter extends around the stem 65 and has one end thereof in abutment with the inner end of the bolt and its other end in abutment with a shoulder 69 at the inner end of the bore 62. In connection with manipulation of the crossbar 21 into its operative position after swinging of the sides 20 into their up position the outwardly extending tongue 57 is first inserted into the slot 58. Thereafter the end of the crossbar that has the depending hook 59 is swung downwards so as to bring the hook into straddled relation with the upper distal corner of the adjoining side 20. The outer end of the bolt 63 is undercut to form a cam 70 which in connection with downward swinging movement of the hook equipped end of the crossbar engages the portion of the adjoining side 20 that directly overlies the slot 64 and coacts therewith to shift the bolt inwards. As soon as the hook equipped end of the crossbar is swung downwards to its fullest extent and the outer end of the bolt is aligned with the slot 64 the compression spring 63 forces the bolt outwards into interlocked relation with said slot. When it is desired to remove the crossbar after use of the auxiliary seat the bolt 63 is slid inwards so as to withdraw the outer end thereof from the notch and thus free the crossbar so that it may be swung upwards as a preliminary to withdrawing the tongue 57 from the slot 58. Inward sliding movement of the bolt is effected by gripping the finger piece 67 and moving it inwards so as to retract the bolt against the force of the spring 68. The finger piece 67 coacts with the ends of the slot 66 to limit inward and outward sliding movement of the bolt.

The baffle plate 22 is located at the front portion of the base 18 and is of materially greater length than width. The central portion of the baffle plate is connected by a hinge 71 to the portion of the base 18 that defines the front of the aperture 23 in order that it is capable of swinging back and forth between a down position wherein it extends horizontally and one end portion thereof rests on the front portion of the base and its other end portion overlies the front of the aperture 23 (see Figure 1), and an up position wherein it extends substantially vertically and its one end portion projects above the base and its other end portion-projects downwards into the front portion of the bowl 10 (see Figure 2). When the plate 22 is in its up position in connection with use of the auxiliary seat it serves to deflect downwards into the bowl any liquid stream that is directed thereagainst. The hinge 71 comprises a fiat plate 72, a flat plate 73 and a pintle '74. The plate 72 fits snugly within a recess 75 in the front portion of the upper surface of the base 18 and is suitably secured in place by screws or other attaching means. The plate 73 of the hinge 71 fits within a recess 76 in the central portion of the bafile plate 22 and is suitably secured in place. The pintle 74 extends through eyes on the ad- I joining side margins of the plates 72 and 73. The baffie plate 22 is so shaped that when it is in its down or inoperative position it fills the cutouts 53 in the front distal corners of the sides 20. The thickness of the baifie plate is the same as that of the back 19 and the sides 20 and hence when the bafiie plate is in its down position its upper surface is flush with the upper surfaces of the back and the sides of the auxiliary seat. When the baffle plate is in its up or operative position the upper end thereof fits within, and is in interlocked relation with, the central portion of the crossbar 21 as shown in Figures 2, 3, and 8 of the drawings. Because of this the crossbar has a twofold purpose in that it serves not only to hold the sides 20 in their operative position, but also firmly or fixedly to hold the bafiie plate 22 in its up position. The upper end of the baffle plate is provided with a notch 77 for receiving a downwardly extending lug 78 on the central portion of the top wall 5'4 of the crossbar 21. The notch and the lug serve when the baifle plate and crossbar are in connected relation to form a readily releasable interlocking connection whereby the crossbar is held against longitudinal displacement relatively to the baffle plate. The upper end edge of the bafiie plate is curved conformably to the front portion of the outer edge of the base 18.

The portions of the base 18 that are outwards of the sides 26 have upwardly extending integral enlargements 79, the top surfaces of which are flat and lie in the same plane as the upper surfaces of the back 19, the wings 36, sides 20 and the baffle plate 22 when the back, wings, sides and bafiie plate are in their down or inoperative position. By having the top surfaces of the enlargements 79 lie in such plane the entire top of the auxiliary seat is flat when the seat is in its collapsed position and hence the auxiliary seat may be used, if so desired, as a cover for the regular toilet seat 9. However, if desired, a standard or conventional cover 80 may be employed. If such a cover is employed it is provided at the rear portion thereof with hinge brackets 81, certain ends of which are attached to the rear portion of the cover and the other ends of which are provided with eyes 82 which surround the intermediate part of the inverted U-shaped bracket 15 constituting part of the hinge 14. The hinge brackets 81 permit the regular cover 80 to be swung back and forth between an operative position wherein it overlies the auxiliary seat and an inoperative position wherein it extends upwards and rearwards.

When it is desired to use the auxiliary seat the back 19 is first swung upwards and forwards into its up position. Thereafter the hinged wings 36 at the ends of the back are swung rearwards until they are arrested by the upstanding bosses 43 and extend at right angles to the back for back supporting purposes. After the wings 36 are manipulated into place the sides 20 are swung upwards and outwards into their up position wherein the rear end margins thereof are engaged by the lugs 45 on the distal side margins of the wings 36. Thereafter the child desiring to use the auxiliary seat is placed in a sitting position on the portions of the base 18 that surround and define the aperture 23. After the child is properly positioned the baffie plate 22 is swung into its up position. In such position the upper end portion of the baffle plate is disposed between the thighs of the child. After upward swinging of the baffle plate the crossbar 21 is manipulated into its operative position as hereinbefore described. In connection with manipulation of the cross bar into its operative position the central portion of the crossbar is brought into straddled relation with the upper end of the bafile plate in order that such portion of the crossbar serves to hold the battle plate in its up position.

After use of the auxiliary seat the crossbar 21 is removed and then the child is removed. After removal of the child from the auxiliary seat the sides 20 and the baffle plate are swung into their down position. Following this operation the wings 36 are swung forwards into coplanar relation with the back 19 and then the back and wings are swung rearwards and downwards into their down position.

The herein described auxiliary toilet seat is essentially simple in design and may be produced at a comparatively low cost. It effectively and efficiently fulfills its intended purpose and is characterized by the fact that, due to its particular construction and design, it may be used when in its folded position as a cover for the regular or conventional toilet seat with which it is associated.

The invention is not to be understood as restricted to the details set forth since these may be modified within the scope of the appended claims without departing from the spirit and scope of the invention.

Having thus described the invention what I claim as new and desire to secure by Letters Patent is:
