Aug. 22, 1961 s. LEPTRONE LOCKING DEVICE FOR TOILET SEAT COVERS Filed April 6, 1959 INVENTOR.

ATTORNEY United States Patent Office Patented Aug. 22, 1961 2,996,731 LOCKING DEVICE FOR TOIIJET SEAT COVERS Samuel Leptrone, 2291 Gulf to Bay Blvd.',

Clearwater, Fla. Filed Apr. 6, 1959', Ser. No. 804,24

3 Claims. (Cl. 4- 253) The present invention relates .to a locking device which may be attached to toilets to prevent raising of the toilet seat cover by a child so young as to be unable to comprehend the proper use of the toilet.

The principal object of the present invention is to provide a device which can be readily attached to the conventional pivoted toilet seat cover and front wall of the water tank of a commode and which is operative to block the cover in its seat covering position until released by the actuation of a key member so that children of such young age that they are unable to understand the operation of the key cannot open the cover and gain access to the toilet bowl, which situation frequently results in such children throwing articles into the bowl or playing in the water therein which is highly undesirable from a health and sanitation viewpoint.

Another object of the invention is the provision of a toilet seat cover locking device of the character described comprising two rigid bar members arranged end to end and having means to attach the outer ends thereof to the toilet seat cover and the adjacent vertical wall of the water tank for the toilet respectively, the inner adjacent ends of the bars being pivotally connected to a link at spaced points to provide a double hinge connection between the bars, and key means to lock the bars and link in a rigid, preferably aligned, position to provide a strut for blocking raising of the seat cover, the key being operative to release the bars and link to permit pivotal movement thereof so that the seat cover can be raised, the spaced pivots for the bars on the link providing a selfadjusting hinge to accommodate varying positions of the hinge pivot for the seat covers of toilets having different spacing of the seat cover hinge and water tank walls.

A further object of the invention is the provision of a device of the character mentioned which can be attached and detached from the seat cover and water tank of a toilet without altering the construction of the toilet so that the device can be readily applied to any of many different toilets and can be removed after the child or children having access to the toilet have become trained to the proper use thereof.

Other objects and advantages of the invention will be apparent from the following description of a preferred embodiment of the invention, reference being made to the accompanying drawings wherein FIG. 1 is a side elevational view of a toilet having a device embodying the invention attached thereto, a portion of the toilet being shown broken away;

FIG. 2 is a view taken substantially along line 22 of FIG. 1 but on a larger scale;

FIG. 3 is a fragmentary side elevational view of the toilet with the seat in the raised position;

FIG. 4 is a fragmentary view of a part of the cover locking device as shown in FIG. 2, but on a larger scale; and

FIG. 5 is a sectional view taken on line 5-5 of FIG. 2, but on a larger scale.

Referring to the drawings, a conventional toilet is shown including a bowl 10, a seat 11, a seat cover 12, and a water tank 13. The seat and its cover are attached to a hinge 14 so that they may be raised individually beyond a vertical line, as is usual. Cover 12 not only overlies seat 11 but also forms a cover for the open top of the bowl, as is well known.

Thg seat cover locking device comprises two rigid bar members 18 and 19, which may be formed of suitable material, such as aluminum, each having means to attach the outer ends thereof to seat cover '12 and the front wall 15 of water tank 13. Preferably, these means comprise rubber suction cups 20 and 21 pivotally attached to bars, 18 and 19, the cups having lugs 20a and 21a provided with Openings therethrough which receive supporting fingers 18a and 19a respectively, formed by L-shape cutaway portions in the end portions of the respective bars. Suction cups 20 and 21 are of the well known type, being formed of rubber or like material and having a circular concave face, such as shown at 21b, which may be pressed to a smooth surface and retained there by atmospheric pressure due to the expulsion of air from the recessed face by the compression of the cup, as is well known.

The inner ends of bars 18 and 19 are pivotally connected to a cross-shape rigid link 22, and in the form shown, the link includes neck portions 22a and 22b which extend into notches 18b and 19b formed in bars 18 and 19, respectively, as best seen in FIG. 4. The notched 'end portions of bars 18 and 19 and the neck portions to provide a double hinge structure. Any other suitable hinge construction detail could be employed, however.

Means are provided for locking bars 18, 19 and link 22 in an aligned, rigid position for form-ing a strut, and in the form shown, this is accomplished by a flat slide bolt or key 26 which is somewhat narrower than bars 18 and 19, and the upper end of which is provided with an outturned portion 26a which serves as a handle by which the key can be moved longitudinally of the bars. Key 26 slides in guides 27, 28 and 29 located on bar 18, link 22 and bar 19, respectively, which guides each comprise an inverted channel shape metal member having out-turned flanges 30 which are riveted to the bar 18, link 22 and bar 19, respectively, by rivets 30a. The guide openings are in alignment when the bars and link are aligned so that key 26 may be moved therethrough and maintain the bars and link rigidly aligned as shown in FIGS. 1 and 2.

Preferably key 26 is automatically moved to its lock-- ing position and for this purpose a lug 26b having an eye therethrough is formed on key 26 near handle 26a but projecting from the opposite side thereof and extending through a longitudinal slot formed in bar 19. A tension spring 31 is attached at one end to the eye in lug 26b and the opposite end is attached in an eye formed in a lug 19d attached to the rearward side of bar 19, as viewed in FIG. 2. Slot 19d is of such length that spring 31 may slide key 26 through guides 27 and 28 when the bars 18, 19 and link 22 are moved into alignment, as shown in FIGS. 1 and 2; Handle 26a engages guide 29 to limit movement of the key by the spring.

In use, the device is applied to the toilet by securing suction cup 20 to seat cover 12 and suction cup 21 to wall 15 of the water tank so that when the cover is in its seat covering position, bars 18, 19 and link 22 are in alignment as shown in FIGS. 1 and 2. Spring 31 then moves key 26 downwardly through guides 27, 28 and 29 so that the bars and link are locked in alignment and form a strut which prevents a young child from raising the cover.

To open toilet seat cover 12, it is only necessary for a person to place a finger beneath handle 26a and slide key 26 upwardly thereby removing the key from guides 27 and 28 so that the bars can pivot relative to the link and permit raising of the seat cover as shown in FIG. 3. When finger 26a is released, spring 31 urges key 26 downwardly, as viewed in FIG. 3, and the lower end of the key abuts link 22 which is now at an angular position relative to the travel of the key and forms a stop for the key. When seat cover 12 is moved to its lowered position, bars 18, 19 and link 22 are once again aligned and spring-31 moves key 26 through guides 27 and 28 to the locking'position thereby automatically locking the bar's'in rigid alignment to block opening of the seat cover;

Link 22 provides a double hinge for bars 18 and 19 which permits locking devices of a single design to be used on toilets having dilfer'enfrelative locations of'the' hinge structure for the toilet seat and cover and the front wall 'of the water tank,'so that one production model will operate on many different makes of toilets.

It-will be appreciated that theprocedure for unlocking the seat cover lock device is sufficiently complicated to forestall operation by children so young as to be untrained to the proper use of toilets, but children having proper training and understanding can easily operate the device.

It will also be apparent that when the need for locking a toilet seat cover against unnecessary opening is passed, the locking device can be readily removed from the toilet and no evidence of its attachment will remain.

Although but one form of the invention has been described in detail, it Will be understood that other forms, modifications and adaptations thereof could be made, all falling within the scope of the invention as defined in the appended claims.
