Description

CROSS-REFERENCE TO PROVISIONAL APPLICATION

This application is a convention filing of this application as a provisional on Mar. 28, 2013 as provisional application Ser. No. 61/806,126.

BACKGROUND OF THE INVENTION

1. Field of the Invention
This invention relates to bathrooms in general and more particularly, to toilets and specifically to the mechanisms assisting the using in lifting the seat and/or the lid for toilets.
2. Background
The definition of a toilet is a seat with a container below it, which is used primarily for disposing of human waste. In modern culture, a toilet includes not only a seat and a container, but also includes a lid covering the seat. Obviously, in order to properly use the toilet, one must be able to lift the seat and lid. Unfortunately, for many, this is not possible.
Many folks have lost the complete or partial use of their arms and hands. For example, returning war veterans sometimes lose the complete or partial use of their hands or arms. Others afflicted with a neuromuscular disease, such as ALS end up being so weak that they cannot lift the toilet elements including the seat and the lid. Accidents, whether recreational or on the job claim the use of many folks hands and arms.
More commonly back problems prevent a number of people from bending over so that they can properly lift the toilet seat or lid. Back problems can cause muscle weakness and of course, pain and in all, prevent such sufferers from being able to lift or lower a lid or a seat. Less prevalent, but not uncommon, are surgical procedures, which have at least the same effect, if only for a temporary period of time.
When the lid and seat are left open, unsanitary and unsafe conditions naturally result. This is especially true in general health care public facility, where large numbers of persons having such afflictions are present. In fact, it is sometimes said that the most dangerous place in the hospital is in the room of a patient who is incapable of properly using the rest room facilities, including not lowering the toilet seat or lid. The combination of this condition and of a large number can be especially alarming.
The solution to such issues is to provide a person incapable of raising and lowering the toilet seat or lid with their hands and/or arms, a hands free way to raise and lower the toilet seat and the lid. Moreover, even healthy people prefer not to touch the seat or lid of a toilet used by others. Reducing the amount of contact with the toilet seat and lid naturally reduces the risk of sickness and serious illness, especially in public places like hospitals.

DETAILED DESCRIPTION OF THE INVENTION

The invention will now be described with respect to FIG. 1, which illustrates an exemplary embodiment of the invention shown generally by the numeral 10 attached to a conventional toilet. The conventional toilet includes a container, a seat over the container. The toilet includes a lid covering the seat and the container. The toilet further includes a lifting mechanism for disposing of the contents within the container.
The hands free lifting mechanism, generally indicated by the numeral 10 includes foot pedal assembly 12, a stabilizing rod member 14 and a lifting assembly 16.
The foot pedal assembly 12 will be described with respect to FIGS. 1-3. The foot pedal assembly 12 includes two pedals 18 and 20. Each pedal, 18 and 20 operates independently. One pedal raises the lid and the other pedal raises both the lid and the seat. It will be appreciated that the independent operation of each pedal is somewhat limited. For example, the seat cannot be raised higher than the lid and the lid cannot be lowered more than the seat.
As shown in FIG. 2, the foot pedals 18 and 20 are in the start position. In this position, the seat and the lid are closed. The foot pedal assembly 12 includes a supporting rod member 22 and a base 24. The pedals 18 and 20 are pivotally connected to the base 22 at pivot member 26. The base 24 includes guide 28.
The supporting rod member 22 is pivotally connected to the pedals 18 and 20 at pivot member 30. Additionally, the supporting rod member 22 has a guide bearing 32, which slides within guide 28 as the foot pedals 18 and 20 are depressed and released as shown more clearly in FIG. 3. As the foot pedals 18 and 20 are depressed, the guide bearing 32 slides along and within guide 28. In the exemplary embodiment of FIG. 2, the guide 32 includes a roller bearing 34 to facilitate the ease of travel along the guide 28. This also provides a smooth and stress free operation of the foot pedals 18 and 20 and lessens the needs for force required to lift the seat and/or lid.
The guide 28 has a distal end 40 and a proximal end 42. Located at the distal end 40 is a passive locking and unlocking member 50. As the foot pedals 18 and 20 are depressed or released, the release of pressure from the foot, in effect, activates the passive locking and unlocking member 50. Thus, should there be a sudden release of pressure from the foot as the pedals 18 and 20 are being depressed, the passive locking and unlocking member 50 holds the pedals in the position where last pressure was applied. This prevents the slamming down of the seat and/or lid because the user's foot accidentally slipped off the pedals.
At the proximal end of the guide 28, there is located the soft lowering member 60. As can be appreciated by those familiar with the art, the lid and seat have considerable weight. In order to prevent gravity from taking over and simply slamming down the seat and/or lid, the foot pedal assembly 12 is provided with a soft lowering member 60. The a soft lowering member 60 includes an adjustment knob 62 and a contact point 64. Additionally, the bearing member 32 includes a landing block 66. Upon sudden release of pressure on the foot pedals during lowering of the seat and lid, the fail safe situation occurs such the a soft landing is made as the contact point 64 engages the block 66 preventing the slamming effect that might otherwise have occurred by gravity. The adjustment knob 62 allows adjust of the contact point so that the lid and seat close properly without allowing slamming of the same.
As shown in FIG. 3, the foot pedals 18 and 20 are in the start position, while the seat and lid are closed. As pressure is applied to the foot pedals in the direction of the arrow 13, the foot pedals are depressed toward the base 24. The bearing 32 travels from the proximal end of the guide 28 toward the distal end and the foot pedals 18 and 20 and collapses onto the base 24 in the finishing position.
With particular reference to FIGS. 2-4, the operation of the stabilizer rod member 14 will be described. The stabilizer rod member 14 is adjustable so that it will fit a wide variety of different toilets. In the exemplary embodiment shown in FIGS. 2-4, the rod member 14 comprises a stiff rod and includes a telescoping rod that can adjust to any height desired. A locking ring 70 is provided to assure that the rod member 14 remains at the desired height. In order to adjust the height, the locking ring 70 is loosened and the height re-adjusted and then the ring 70 once again tightened.
A cable 72 is attached to the foot pedal 20 at one end and the lifting mechanism 16 at its other end. The cable 72 is threaded through the rod member 14. The rod member 14 stabilizes the cable 72 and also the foot pedal assembly 12. As can be appreciated, as the foot pedals 18 and 20 are depressed and released, the cable moves accordingly. It will be appreciated that in the exemplary embodiment shown, only one cable, namely 72 is shown attached to the foot pedal 20. However, there are actually two cables, one for each foot pedal. In the exemplary embodiment, the foot pedal 20 operates to lift and lower the lid and the foot pedal 18 operates to lift and lower both the lid and the cover together. In other exemplary embodiments, different configurations are with the spirit and scope of the invention. For example, each foot pedal 18 and 20 may operate independently and one operates the lid while the other operates only the seat.
With particular reference to FIG. 4, there is shown the remaining portion of the lifting mechanism generally designated by the numeral 16. The lifting mechanism 16 includes a spool housing 80 having a spool 82 and 83 for each cable. The other end of each cable is firmly secured to each of the spool(s) 82 and 83.
The lifting mechanism 16 additionally includes a cylinder housing 84, which houses two concentric lifting cylinders 86 and 88. The two concentric lifting cylinders 86 and 88 are spaced apart by a ball bearing member 90, located at each end of the cylinder housing 84. In another exemplary embodiment, the ball bearing member 90 is replaced by a roller bearing member. The ball bearing member 90 allows smooth and independent operation of one lifting cylinder relative to the other. Again, such enhancements, favor a stress-less lifting and lower of the seat and lid.
In the exemplary embodiment of FIG. 4, the lid lifting cylinder is cylinder 84, while the seat lifting cylinder is 86. The lid lifting cylinder is cylinder 84 comprises a solid cylindrical rod and has a clasp 92 connected to it. The clasp 92 is then attached to the lid, so that in response to rotational movement of the lid lifting cylinder 84, the lid is either raised or lowered. Similarly, the seat lifting cylinder 86 has a clasp 94 connected to it, which is then connected to the seat for similar raising and lowering of the seat.
As shown clearly in FIG. 4, the lifting mechanism 16 includes a first cable 72 as previously discussed and a second cable 73. The cable 72 ties into the spool 82 as noted above. The spool 82 is connected to the inner solid lifting cylinder 86, which as noted above is connected to the lid. Once foot pressure is applied to the foot pedal 20, which controls cable 72, the cylinder 86 rotates accordingly, the cable is wound onto the spool 82 raising the toilet lid.
Similarly, the cable 73 is securely attached to the spool 83. The spool 104 is connected to the lifting cylinder 88, which as noted above, is connected to the toilet seat. The toilet seat raises or lowers in response to the rotation of the lifting cylinder 88. Likewise, upon the depression of foot pedal 18, the cable 73 winds up onto the spool 83 causing the seat and lid to be raised. It will again be appreciated that different configurations of this construction are possible such that the lid and seat movement are completely independent within the physical limits noted above within the spirit and scope of the invention.
Each of the spools 82 and 83 include a main body and side guards 106. The side guards 106 sandwich the respective cable within the main body and prevent the cable from spilling off of the respective spool.
With particular reference to FIG. 5, there is shown, another exemplary embodiment of the hands free toilet in accordance with the invention. In this embodiment, the seat includes a spring 120 on either side of the mid-line of the seat. The spring 120 normally urges the seat to the open position. Thus, when the foot pedal 18 is depressed, less pressure is needed to open the seat and lid. This is especially important with patients have systemic neuromuscular diseases such as ALS and other having less than ideal strength in their legs. For example children would greatly benefit from the addition of the spring 120.
While the foregoing detailed description has described several embodiments of the hands free lifting mechanism in accordance with this invention, it is to be understood that the above description is illustrative only and not limiting of the disclosed invention. Particularly, various configuration of the foot pedals can be used within the spirit and scope of the invention. Additionally, more complex systems of cables and pulleys can be used to the same effect also within the spirit and scope of the invention. It will be appreciated that the embodiments discussed above and the virtually infinite embodiments that are not mentioned could easily be within the scope and spirit of this invention. Thus, the invention is to be limited only by the claims as set forth below.
