BACKGROUNDOver the years, a fair amount of human ingenuity has been devoted to solving the problem of the toilet seat that was left up. While one would think that such a simple problem should easily yield to the persistence of human efforts, the surprising reality is that virtually no home, office or public facility is equipped with an apparatus that provides a satisfactory solution.
One reason that we do have a toilet seat lowerer is that the solutions that have been, devised so far are all too complicated or too expensive. For instance, some devices have expensive pneumatic mechanisms, others have two many levers, gears, rods and wires.
It would be useful, therefore, to have an apparatus that would allow one to easily lift a toilet seat by foot (without using one's hands) and have the seat always return without slamming to the rim of commode when the lifting mechanism was released. It would also be useful if such an apparatus, was inexpensive, easy to assemble so that any toilet could be retro-fitted with the apparatus, durable so that it could tolerate many uses over the years, and easy to clean and repair.
SUMMARYThe present disclosure describes a foot-operated apparatus for lifting and lowering a toilet seat that, is simple to use, easily and inexpensive to manufacture and easily installed on an existing commode. The apparatus is affordable and may be retro-fitted to most existing toilets in private homes and public facilities where toilets exist. A base support is adapted to attach to an existing tile, wood, cement or concrete flooring surface using a loop and hook fastener with an adhesive material on the opposite sides of loop and hook piece allowing the base to be easily installed and easily removed for ease of cleaning the unit and the area around the toilet. The design the base is of the correct mass and size to allow the pressure exerted upon the lever and foot pedal to maintain long term repetitive actuation of said lever with out concern of failure.
A lever foot pedal mounted in the base may be a single unit made of extruded and molded poly carbonate material for durability and corrosion resistance. A push rod pivotally connected to the foot pedal and pivotally connected to the toilet seat lifts and lowers the seat upon foot actuation and release, respectively.
The disclosure contemplates lots with the disassembled parts of the apparatus and written instructions for assembly. Optional parts may include but not be limited to a cushion disposed in the base to prevent the toilet seat from slamming down; a decorative cabinet to house the apparatus, appliques on the foot pedal to enhance grip and reduce slippage; and even a sleeve for the foot pedal to provide comfort for bare foot users.

Referring now to
An apparatus of the present disclosure may be positioned along side commode 110. Base 130 is slotted 132 to accommodate foot pedal lever actuator 134. A lever fulcrum may be formed by axle 136 disposed across slot 132 through rail bore 138. Axle 136 extends through bore 215 of foot pedal 134 at approximately the mid point of pedal 134 so that pedal 134 rotationally pivots around axle 136. Push rod 150 attached to pedal 134 pushed seat up 120 with attachment 710 connected to push rod 150 by connector 650.
In a preferred embodiment, base 130 is secured to the floor next to commode 110, or on a base or flange (not shown) extending from the bottom of commode 110, to prevent base 130 from slipping when force is applied to foot pedal 134. For example, base 130 may be secured to the floor with a mount such as a hook an loop attachment such as Velcro having an adhesive surface on each of the hook and loop pieces so that the attachment pieces can be adhered to the bottom of the base and to the floor or other suitable surface without the use of a tool.
Leaf spring 140 may be secured between the rails 210 and 212 of slot 132 toward the front or proximate side of base 130 in relation to axel 136 so that leaf spring 140 becomes compressed when foot pedal 134 is actuated in the down position (to lift seat 120). Upon release of the actuating force from pedal 134, leaf spring 140 returns to its equilibrium, transmitting upward force to pedal 134.
The rear or distal end 142 of foot pedal 134 may be pivotally connected to push rod 150, which in turn may be pivotally connected to seat 120.
Base 130 may be secured from slipping by fastening it to a suitable surface nearby to the commode, such as the floor or the base of the commode. Velcro or other loop and hook type fastener may be a suitable fastener, for example, but other modes of securing base 130 such as screws, nails, glue or other adhesive such as a cured adhesive like epoxy, snaps and so forth are contemplated by the present disclosure. Another way to keep base 130 from slipping may be to supply additional weight to base 130 with, for example, sand, ball bearings, or water supplied into a reservoir (not shown) in base 130, or by attaching some other weight such as a heavy metal to base 130.
The means of securing base 130 may be selected depending on the nature of the surface to which it will be secured. Many toilets have tile or stone floors that may be problematic for the use of nails or screws but which may be well suited for adhesive or Velcro-type fastening.
Leaf spring 140 may be attached to base 130 (
A specific exemplary embodiment of such an adaptation may provide for example a slotted hole 518 sized to received both a push rod member and a connector such as a cylindrical axle/washer or screw/nut arrangement, or other suitable connection means, to connect push rod 150 to distal end 142 of pedal 134. Push rod 150 may also provide a slotted hole 518 to receive the connector. A slotted hole allows the entire pedal/push rod assembly to adjust to the dynamic angle changes that occur at the connection point between pedal 134 and push rod 150 during actuation and release of the seat-lifting apparatus.
An alternative embodiment provides a distal end 142 of pedal 134 with a connection bore sized to accommodate a flared dual split axle pin connecting pedal 134 to push rod 150.
Adhesive appliques such as sandpaper or decorative forms may provide a slip-resistant surface on pedal end 512. A decorative or soft sleeve, such as sheep skin, carpet upholstery and so forth that can be slipped over the foot pedal splayed portion 512 may also be provided to provide tactile comfort to barefoot users.
Bottom push rod 152 may be 0.25 inches in diameter and preferably fabricated from corrosion resistant material. Lower end 154 of bottom rod 152 may have a relatively flattened area 820 to fit vertically within slot 518 of foot pedal 134 with, bore 810 to receive a cylindrical connector 805 transversely perpendicular to the vertical installation of push rod 150, as discussed above. Connector 805 inserts through the slotted hole 518 in the end of the foot lever pedal 134 and extends through bore 810 of bottom rod 152. Cylindrical connector 830 may have head 830 and threads 840 to retain nut 850, which keeps bottom push rod 152 and connector 805 from inadvertently disconnecting from foot lever pedal 134 but allowing removal for cleaning.
An alternative embodiment of bottom rod 152 provides a 0.5 inch bore to receive a connector, which in this embodiment may consist of a flared dual split axle pin cylindrical transverse connector 650 connected to pedal 134.
Top end 155 of bottom push rod 152 may be 16 UNC male threaded for connecting to turn buckle 159 having sufficient thread length to allow for appropriate adjustments for the differing heights of the toilets now manufactured and installed through out public and private facilities.
Top push rod 156 may be approximately 0.25 inches in diameter fabricated from corrosion resistant material and provides bore 640 to receive cylindrical transverse connector 650. The connector 650 may be rotatably disposed with receptacle 720 of toilet seat fastening attachment 710 (See
The lower end of top push rod 156 may be 16 UNC male threaded for connecting to turn buckle 159 and with adequate thread length to allow for appropriate adjustments for the differing heights of the toilets now manufactured and installed through out public and private facilities worldwide.
Turn buckle 159 may be a 0.25 inch female 16 UNC threaded connector with opposite threads on each end for adjusting push rods 152, 156 for the differing heights of the toilets now manufactured and installed through out the public and private facilities. The turn buckle is fabricated from corrosion resistant material and is sized for durability and strength.
Fastener or connector 710 may provide tubular receptacle 720 to receive a cylindrical connector 650 to connect upper rod 156 of push rod 150 to seat 120. Connector 650 may be, for example, a dual split end axle pin extending from push rod 150. Flanges 732, 734 extend from two sides of receptacle 720 to facilitate adherence of fastener 710 to seat 120. Lid fastener 710 may be fabricated as a unitary piece from corrosion resistant and flexible material. Flexibility is preferred so that receptacle 720 may twist in response to forces from push rod 150 and seat 120 as the angle of connection dynamically changes when seat 120 is raised and lowered by operation of the present apparatus. Flanges 732, 734 may extend for a length sufficient to tolerate such twisting angular forces. Adhesive material on flanges 732, 734 may secure the flanges to the underside of the toilet seat 120.
Distal bore 518 of pedal 134 retains the lower push rod assembly 805. Lower push rod assembly 805 may include bolt 830, nut 850 and threads 840 to retain nut 850 in relatively loose engagement with pedal 134 (via bore 518) so that a certain amount of play is allowed in the connection to accommodate the dynamically changing angles a, b, a′ and b′ during operation of the apparatus. Turn buckle 159 threadedly and adjustably attaches to threads 840 of assembly 805 and to upper rod 156. Connector 650 attaches to rod 156 through bore 640 and to seat attachment 710 through bore 720.
