TOILET SEAT HINGE AND STOP Filed Dec. 30, 1947 INVENTOR 650E615 VMDEBEL L ATTO R N EY Patented Dec. 26, 1950 TOILET SEAT HINGE AND STOP George W. De Bell, East Chatham, N. Y., assignor to Beneke Corporation poration of Mississippi Columbus, Miss., a cor- Application December 30, 1947, Serial No. 794,513

2 Claims.

The present invention relates to seats for sanitary appliances, and more particularly, to an improved hinge combined with a novel stop for a toilet seat. The novel hinges of this invention are used in pairs to provide a swingable support for a seat. The novel check or stop feature of the hinge of this invention resiliently cushions and checks the movement of the seat when it is raised.

The type of toilet used in institutions and factories is generally installed in a position spaced from an adjacent Wall or the side of an accompanying tank. It is therefore desirable to provide a stop for the seat when it is raised. A mounting place for a stop is not conveniently available, either on the porcelain body of the toilet, or on the plumbing connections. In accordance with the present invention, not only is an improved seat hinge provided, but the problem of providing a stop for the seat is solved in a novel manner.

One object of the invention, therefore, is to provide a novel combined hinge and stop for a toilet seat.

Another object is to provide novel means for mounting a hinged fitting on a toilet seat without need for a separate elastic part such as a top washer.

A further object is to provide a novel hinge of unitary structure combining the hinge pin and securing means in one part.

A still further, and closely related object, is to provide a yielding body of novel structure win which the hinge pin and securing means as a unit is embedded.

A still further object is to provide a novel elastic stop to check the rearward movement of a toilet seat and to maintain the seat in a raised position.

Other objects and advantages of the present invention will become apparent and immediately suggest themselves to those skilled in the art to which the invention is directed from a reading of the following specification in connection with the accompanying drawings in which:

Fig. 1 is a View in perspective of a toilet and seat showing an installation comprising a pair of combined hinges and stops of the present invention.

Fig. 2 is a view in side elevation to a different scale of a combined hinge and stop constructed in accordance with the invention.

Fig. 3 is a view partly in section of the hinge of Fig. 2 as viewed from the right of Fig. 2; and

Fig. 4 is a view in plan of the hinge of Fig. 2 with a fragmentary showing of a seat.

Referring to the drawing, and for the present to Fig. 1 thereof, reference character H1 indicates a toilet bowl having a top rim l2 and a pro jecting shelf l4 provided with holes l6 (Fig. 3)

for accommodating hinge bolts for a seat. The seat is indicated by the reference character 13 and is of usual construction, except for slight modifications to be pointed out hereinafter. Each hole [6 is employed, as shown by Figs. 1 to 3 of the drawings, for receiving the projecting threaded end 20 of the combined hinge and stop of this invention. The right hand hinge and stop is indicated generally by the reference character 22. The left hand hinge and stop is indicated by the reference character 24. Inasmuch as both of these devices are generally th same except for a reversal of certain of the parts, only one, the left hand hinge and stop 24 will be described in detail hereinafter with reference to Figs. 2 to 4 of the drawings.

The seat I 8 has a projecting part 26 and angular recesses 28. The proiecting part 25 has a bore 29 therein which is or may be reinforcedv with a tube 31 of steel, brass or the like. The tube is useful where the seat is made of a plastic material in the modern manner.

The combined hinge and stop 24 (and also the hinge and stop 22) comprises a body part 33 and an angular metal part 35. The latter includes the previously mentioned threaded end 20 and a hinge pin 38. The part 4! between the end and the hinge pin may be curved as shown to romote ease of manufacture. The body part 33 is preferably made of a more or less yielding material. Many plastics, including rubber, are suitable. Vinyl plastic and ethyl cellulose may also be used. If rubber is used, for example, it is preferably mechanical rubber with a hardness of to 96 as indicated by the duron' eter and it should be resistant to acids and alkalis found around toilets. Good aging characteristics are also desirable.

The body part 33 is formed to have an enlarged flange 44. A part 46 of increased size or diameter on the metal part 36 is embedded in the flange 4'4. The enlarged part may be a washer welded, brazed, staked or otherwise secured to the shank 2B. The large diameter part 46 causes the part of the body 33 generally beneath it to serve as a washer thus avoiding the need for the separate elastic washer usually used. The shank 20 has a nut 48 theron which clamps the device 24 in place on the shelf M.

A metal washer 5| is preferably used and a washer 52 of yielding or elastic material may be used, if desired. In view of the yielding nature of the body part 33, the washer 52 is not strictly necessary, but may be desirable to avoid crushing the fragile edge of the hole It in the porcelain.

The hinge pin portions 38 of the metal parts 38 of both devices 22 and 24 project into the tube 3| in the seat so that the seat is free to swing to the raised position shown in Fig. 2 and indicated by reference character 52. In this position it is inclined beyond the vertical and rests against a projection 56 on a stop portion 58 of the body 33.

The projection Fails-"the result of and provides a. recess 6| to accommodate the corner 62 of the seat as the latter swings to the raised position. In

the raised position of the seat, it is or may beinclined at an angle of about 7 to the vertical.

Any other angle of rest may, of course, be selected, the figure above being given only by Way of example. If the seat I8 is raised; rapidly, as it usually will be, the yielding nature of the stop portion 58 will permit the seat to swing to the position 64 shown by dot dash outline on Fig: 2. The angle of the seat in this position is indicated as being about 14 from the vertical. This figure,

again, is given only by way of example. Elasticity.

and toughness of the parts 33 will govern. When theseat is raised with. more or less violence the,

stopportion 58 momentarily assumes the positionfiS indicated in dot dash outline.

When the seat is in the position of Fig. 1 a set of bumpers 68 contacts the rim I2 of the bowl I 0. In order that the seat may be level, the distance of, the bottom. edge of the seat is maintained ject, a section of increased diameter on said shank portion, said section serving to maintain said shank portion in position ;in-.s aid body under a compressive stress thereon, saijdE elastic body having a bumper projection to maintain said seat in a raised position of equilibrium.

2. A mounting for a toilet seat comprising a pair'of combined hinge and bumper devices, a combined, hinge and shank for each device, a yielding body for-each device said yielding body enclosing the. hingeand shank, a section of increased size on said shank, said yielding body having a bumperprojection, a screw thread on said shank to receive a fastening means to fasten said device to a toilet bowl, said section of increased size overlying. and pressing on a portion of theyieldingbody to serve asan elastic washer assaidfastening means is tightened GEORGE W.
