Abstract: A locking shaft extends through passages in a mounting bracket, a seat bracket and a seat cover bracket to prevent small children from raising the seat and seat cover. The locking shaft and a plunger are mounted to an end cap with the plunger being slidable within an axial passage in a rod upon which the brackets are mounted. A spring connected to the plunger inside the axial passage biases the locking shaft toward a locked position. In order to unlock the seat and seat cover, a person must pull the locking shaft out of the passages in the seat bracket and the seat cover bracket and raise the eat and seat cover, or just the seat cover if so desired, after placing the locking shaft in the unlocked position.

Abstract: An apparatus for locking the lid of a toilet includes a strut which is pivotted to the flush tank of the toilet and a coupling which is fixed to the lid. The coupling has a convoluted slot therein through which a portion of the strut is received. In order to unlock the lid one must simultaneously pivot both the lid and strut which requires manual dexterity not yet acquired by most toddlers and young children but possessed by adults and older children, thus protecting toddlers and young children from the dangers of flush toilets.

Abstract: A foot actuated toilet seat lifter is disclosed in which a base member of substantially triangular cross-section is placed on the floor with the apex down. Foot pressure on one surface of the base pivots the base about the apex, causing a shaft to press upward on a bracket attached to the toilet seat, thus lifting the seat. A variety of base shapes are disclosed, together with a bellows for damping seat lowering, and optional means for securing the base to the floor or carpet. All parts are removable to aid in cleaning, and may be installed or removed without tools. The base member may optionally have a continuously curving lower surface, or may be formed of angled material to achieve the same effect as a triangular member. The resulting devices have the advantage of employing very few parts when compared to some prior art lifters.

Abstract: An apparatus for releasably maintaining a toilet seat in a generally vertical position comprises a mounting member adapted to be secured to the toilet tank in a position to engage a toilet seat and maintain the same when moved to a general vertical orientation. According to one embodiment, a hook is forced upwardly due to movement of the toilet seat to the vertical position, and is positioned outwardly at the tank to allow the seat and toilet cover to move past the hook which then maintains these in the vertical position. Manual movement of the toilet seat past the hook will cause the hook to move upwardly to thereby allow the toilet seat to move therepast. As the hook starts to maintain the toilet seat, the toilet cover is also maintained by the hook as it cannot move past the toilet seat.

Abstract: A locking device for preventing unauthorized raising of a hinged toilet lid and the like by an infant comprises a blocking cylinder which is releasably secured to the toilet bowl between the lid hinge and the toilet tank. The diameter of the cylinder is such that it blocks substantial raising of the lid from the closed horizontal position. Quick-release attachment clips allow ready removal of the device by an adult when the toilet is to be used.

Tension elements and a stop element carried by the shoe shelf normally position the control arm long portion and a vertical flange thereon in proximity to the apron surface. Preferably, the lid control arm projects upwardly toward the toilet apron surface at an angle of substantially five degrees (5.degree.).

Abstract: An automatically engageable and quickly and easily releasable locking device for a toilet seat and lid is disclosed. A single mounting bar attached to the underside of the lid carries a pivoted spring-biased locking arm which is released by simple finger pressure and returns automatically to a positive locking position in contact with a stop whenever the lid is closed. No reconstruction or alteration of the conventional toilet bowl or seat and lid structure is required. The locking arm may also be gravity returned to its locking position without spring action.

Abstract: A lock for a toilet lid comprises a bracket securable to a toilet bowl, and a post mounted to the bracket so as to be swingable to a retracted position away from the bowl against a first spring bias. A locking arm is mounted to the post and is movable relative thereto into a position overlying the toilet lid, in order to prevent the lid from being opened. The locking arm is secured to the post in a manner which prevents the locking arm from being moved out of its overlying relationship with the lid unless the post is in its retracted position. The post can be swung 180 degrees to enable the locking arm to be moved to a stored position.

Abstract: A locking device for a toilet seat lid comprises a rotatable lever arm having a downwardly extending flange mounted adjacent the free end thereof. The lever arm is rotatably mounted on a mounting plate with the latter being fastened to the toilet bowl to the rear of the toilet seat by means of the conventional seat-fastening bolts. The flange cooperates with the free end of the lever arm to present a jaw-like structure for receiving a portion of the rear of the closed lid therein. Upon movement of the closed lid towards an open position the lid engages the jaw-like structure in a manner which opposes movement of the lid towards a fully open position. The lever arm is user-rotatable to a position free of the closed lid to allow opening of the lid and access to the toilet bowl. A spring bias on the lever arm returns the lever arm to the original lid-receiving position upon the lid being returned to its closed position.
