The present invention relates to the field of seat lifting systems, and more specifically, to toilet seat lifting systems which allow a user to adjust the height and angle of a toilet seat to assist the user off of the seat.
Conventionally, “standard” toilet seat heights are around 17 inches or less off the ground. In more recent years, “chair height” toilet seats have gained popularity and are usually 17 to 19 inches off the ground. In most cases, consumers choose a toilet height based on personal preference, but there are some people who require a higher toilet seat because of disability or physical limitations.
The elderly, hospital patients, invalids, those suffering from injuries, and other persons with physical limitations may find a conventional height toilet seats provide difficulties when sitting down upon or standing up from. In fact, ADA compliance requires that a toilet seat must be 17 to 19 inches from the ground to the top of the seat. For weak or afflicted persons, it may be impossible for them to be seated on a low toilet without falling or to remove themselves from the seat without assistance.
Higher toilet seat heights may allow persons with physical limitations to seat and remove themselves from the toilet with greater ease, but among shared toilets this may create a conflict between users. Children may have a difficult time seating themselves on a high toilet. This could lead to a child falling or added difficulties to the already hard task of toilet training a child. Additionally, some individuals favor a low toilet seat so they may assume a squatting position when using the toilet.
Based on the foregoing, there is a need in the art for a system in which users may adjust the height of a toilet seat to suit their needs and preferences. Furthermore, what might be desired is a system can raise and lower a toilet seat with little effort and provides a comfortable support mechanism for the user.
In an embodiment, an apparatus is provided. The apparatus includes a toilet seat. The apparatus also includes a first set of actuators coupled to the toilet seat and a second set of actuators coupled to the toilet seat. The apparatus includes a toilet base coupled to the first set of actuators and the second set of actuators. The apparatus further includes a controller coupled to the first set of actuators and the second set of actuators and a power supply coupled to the first set of actuators and the second set of actuators. The apparatus may also include a first support plate attached to a top of the first set of actuators and a top of the second set of actuators. The toilet seat may be attached to a top surface of the first support plate above a through-hole extending through the first support plate. The apparatus may also include a second support plate attached to a bottom of the first set of actuators and a bottom of the second set of actuators. The second support plate may be attached to a top of the toilet base. The second support plate has a through-hole therethrough. The through-hole of the first support plate is aligned with the through-hole of the second support plate. The through-hole of the second support plate aligned with an opening of the toilet base.
In an embodiment, the controller is a switch coupled to the first set of actuators and the second set of actuators. In another embodiment, the controller includes a first switch coupled to the first set of actuators, and a second switch coupled to the second set of actuators. In yet another embodiment, the controller is a button coupled to the first set of actuators and the second set of actuators.
For a more complete understanding of the present invention, the objects and advantages thereof, reference is now made to the ensuing descriptions taken in connection with the accompanying drawings briefly described as follows.
Preferred embodiments of the present invention and their advantages may be understood by referring to the figures, wherein like reference numerals refer to like elements.
In reference to
In another embodiment of the toilet seat height adjustment system, the system is further provided with one or more rear actuators 4. In the embodiment, the housing of the rear actuators 4 are attached to the toilet bowl 2 and the shafts of the rear actuators are attached to the seat 1. In an embodiment, the actuators 3 attach the seat 1 and bowl 2 via fasteners such as screws, rivets, or other fastening means, as are known in the art. In another embodiment, the rear actuators 4 are adhered or precision fit to the molding of the seat 1 and bowl 2. In a preferred embodiment, the rear actuators 4 are attached to the bowl 2 by apertures adapted to fastened onto the bolts provided for the toilet tank. In an embodiment, the rear actuators 4 may be electric, mechanical, or hydraulic, for example.
In an embodiment, the side actuators 3 and rear actuators 4 are attached in a manner to provide a substantial space between the seat 1 and the bowl fitting 9. The space is provided so a user will not get a finger, article of clothing, or part of their body pinched between the seat 1 and the clamps 9.
In an embodiment, the toilet seat height adjustment system is further provided with one or more arm posts 10. The posts 10 extend upwards from the outer edge of the seat 1 and terminate at the front end of the armrests 5. In an embodiment, the back ends of the armrests 5 terminate at a backrest 6. The backrest 6 extends upward from the rear of the armrests 5 to provide support for a user's back as the user places themselves onto the seat 1. In an embodiment, the backrest also extends downward from the armrests 5, attaching to the rear end of the seat 1.
In an embodiment, wherein two armrests 5 are provided, the front end of the right armrest is further provided with a button 7. In an embodiment, the button 7 may engage the side actuators 3 and rear actuators 4 simultaneously to raise the height of the seat. In the embodiment, the user depresses the button 7 to begin raising the seat 1 and releases the button to cease raising the seat 1. In another embodiment, the button 7 may engage the side actuators 3 and rear actuators 4 simultaneously to lower the height of the seat. In the embodiment, the user depresses the button 7 to begin lowering the seat 1 and releases the button to cease lowering the seat 1.
In another embodiment, wherein two armrests 5 are provided, the front end of the left armrest is further provided with a button 8. In an embodiment, the button 8 may engage the side actuators 3 and rear actuators 4 simultaneously to raise the height of the seat. In the embodiment, the user depresses the button 8 to begin raising the seat 1 and releases the button to cease raising the seat 1. In another embodiment, the button 8 may engage the side actuators 3 and rear actuators 4 simultaneously to lower the height of the seat. In the embodiment, the user depresses the button 8 to begin lowering the seat 1 and releases the button to cease lowering the seat 1.
In another embodiment, the front of an armrest 5 is further provided with another button (not shown) to engage a tilt feature. In the embodiment, the user presses the button to engage the rear actuators 4 to raise, tilting the seat 1 to assist the user from the seat. If the user presses the tilt button again, the rear actuators 4 will lower to level the seat 1. In another embodiment, two tilt buttons may be provided. One of buttons may increase the tilt, and the other button may level the seat 1. In another embodiment, the button 7 and the button 8 are replaced with two way switches. One of the switches may will allow the user to raise and lower the seat height, and the other switch will allow the user to increase and decrease the tilt of the seat 1.
In reference to
In yet another embodiment, two rocker switches are provided, with a first rocker switch controlling the side actuators 3 and a second rocker switch controlling the rear actuators 4. By providing independent control or the side actuators 3 and the rear actuators 4, the first and second rocker switches allow for control of height and tilt, and allow for tilt forward or tilt backward.
