Definitions
- shower chairs and shower stools have become increasingly popular in recent years and are presently available in different shapes and materials.
- “shower chairs” will be understood to include “shower stools,” which are only a category of shower chairs where the back portion is missing.
- shower chairs are the safety and comfort provided to users that are unable to remain in a standing position for extended amounts of time or that simply enjoy prolonged showers.
- users are persons of limited mobility or strength, for instance, elderly users; arthritic users; users that have undergone surgeries; or users that are otherwise affected by various medical or age related conditions.
- Other users instead are healthy persons that enjoy long, warm showers for relief in cold climates or for general physical well-being.
- No shower chairs are available at present that are ergonomically designed to provide optimal interfaces with the user's body.
- no shower chairs are available today that offer both ergonomic design and, at the same time, a built in bidet through which the user can clean and soothe the perineal region of her body.
- shower chair designs have been dominated by utilitarian or aesthetic considerations.
- the seat and back portions of presently available shower chairs exhibit flat or U-shaped profiles, but not profiles that reflect body curvatures or that provide optimal weight distribution on the spine of the user.
- Some of the presently available shower chairs have been disclosed in U.S. and international applications; among others, U.S. Pat. No. D355,985 by Swet al., issued on Mar. 7, 1995, discloses an integrally molded, stackable shower chair where the seat and back portions exhibit a shallow U-shape.
- Ergonomic is a scientific term that relates to the interaction between humans and artifacts. Specifically, scientific research during the 20th century has shown that typical sitting postures reduce the static muscular efforts of legs and hips, but also increase physical loads on inter-vertebral discs, in particular in the lumbar (mid-back) region of the spine. Such scientific research is outlined in several articles and treatises, for instance, Gavriel Salvendy, Editor, HANDBOOK OF HUMAN FACTORS AND ERGONOMICS (John Wiley & Sons, 1997, 2nd ed.).
- an ergonomic shower chair must contain features that minimize stress on the users' bodies while maximizing comfort, and at the same time must exhibit design and construction features that are suitable for a shower environment.
- U.S. Pat. No. 5,581,825“Bidet shower Seat” by Honsvald discloses a stool upon which a user can seat or which can be positioned under a support chair, and which includes nozzles on its upper surface directing water onto the genital region of the user.
- This stool has no specific ergonomic features, and includes an interior bowl mounted on the outer body and a number of spray nozzles positioned in the forward and rearward portions of such interior bowl. Water is supplied by attaching a conduit (such as a hose) to a valve and the discharge water is drained through an opening in the central part of the interior bowl.
- U.S. Pat. No. 6,226,810“Portable Bath Seat” by Weddendorf et al., dated May 8, 2001 discloses instead a platform supported by and clamped to the sidewalls of a bathtub, on which a seat is slideably carried.
- this seat may include a bidet attachment essentially consisting of a perforated tube which is snapped into an opening on the seat. Water flows into such tube through a valve connected to a conduit such as a hose and is then drained through holes in the seat.
- prior art does not include a shower chair designed to meet the ergonomic requirements of the user.
- the supply of water into any optional bidets is laborious and requires auxiliary water supply devices, such as a hose.
- One of the objects of the present invention is an ergonomic shower chair that provides the user with optimal comfort and convenience by matching the shapes and characteristics of such chair with the physical shapes and load distributions of a typical user, and that incorporates ergonomic features aimed at reducing spinal disc pressure and at improving blood circulation to the thighs and feet.
- Another object of the present invention is an ergonomic shower chair with a bidet function that is comfortable, effective, and that does not require any specific attachments or set-ups beyond the availability of a typical hand-held showerhead.
- a shower chair that comprises an ergonomic seat portion, an ergonomic back portion and a bidet portion, which is activated by holding a hand-held shower head against the main opening of such bidet portion.
- the seat portion of the present invention is designed to reduce loads on the spine of a seated user, particularly in the lumbar section, and at improving blood circulation in the thighs and feet. Accordingly, the upper surface of the seat portion exhibits double curvatures, with an overall curved surface that includes concave, shallow cavities corresponding to the user's buttocks. This design maintains the user safely into position, but at the same time allows the user to sit comfortably with some “wiggle” room, without being pushed toward the center of the seat.
- a longitudinal perineal groove is located in the central part of the seat portion and houses a series of holes, from which water is discharged from bidet nozzles positioned coaxially within such holes, and at the same time water is drained in the interstices between the bidet nozzles and the inner diameters of such holes.
- This groove extends to the area corresponding to the coccyx (or “tailbone”) of the user for maximum comfort.
- the front edge of the seat portion extends forward in a curved, “waterfall” shape, in order to reduce pressure on the underside of the thighs and to facilitate blood flow to legs and feet.
- Anatomically-contoured hand grips are also carved in each side of the seat, as well as recesses to rest the hand-held showerhead when not in use.
- the seat portion has a hollow structure, with supporting columns positioned longitudinally in the central area, in order to provide rigidity but also produce an effect under the user's buttocks similar to that of a padded seat, further reducing pressure on the user's spinal discs.
- Handgrips, and showerhead holders to rest the hand-held showerhead when not in use, are optionally included in the seat portion.
- the back portion exhibits a front surface with double curvatures, to provide an ergonomic contour corresponding to that of a human back and at the same time relieve disc pressure by re-establishing lumbar curvature.
- the front surface of the back portion is slightly inclined backwards, in order to transfer some of the user's weight against the backrest, further reducing inter-vertebral disc pressure.
- a spinal groove runs longitudinally in the central area, in order to accommodate user's spine.
- the back portion also has a hollow structure, which compresses slightly to provide a comfort level similar to that of a padded chair.
- an anatomically contoured handle is also included in the back portion.
- the bidet portion comprises a main body of tubular form with an elliptical cross-section and a main opening of conical shape. Discharge nozzles protrude from the main body of the bidet portion and are coaxially inserted in some of the drain holes in the seat portion, causing a water spray in the user's perineal area.
- a rubber gasket covers such main opening, in order to eliminate water loss and to relieve pressure on the user's hand.
- Different embodiments of the present invention include means for affixing the hand-held showerhead to the main opening of the bidet portion, or for affixing the hand-held showerhead to the seat portion while the showerhead discharges water into the bidet portion, thereby freeing the hands of the user while water is being sprayed onto the user's perineal area.

Abstract
An ergonomic shower chair with built in bidet, comprising an ergonomic seat portion, an ergonomic back portion with lumbar support, and a bidet portion. Water enters the bidet portion by holding a hand-held showerhead against the main opening of the bidet portion, and is sprayed towards the user's perineal area through bidet nozzles positioned within holes along a longitudinal groove in the seat portion. Because these holes have inner diameters that are wider than the outer diameters of the bidet nozzles, water is drained away through the interstices between the hole walls and the bidet nozzles. The seat portion includes additional drainage holes for fast drainage.
Description
- This application claims the benefit of provisional application Ser. No.60/418,625“Water Spraying Shower Chair” by applicant Moser, filed on Oct. 15, 2002.
- Shower chairs and shower stools have become increasingly popular in recent years and are presently available in different shapes and materials. In the present specification “shower chairs” will be understood to include “shower stools,” which are only a category of shower chairs where the back portion is missing.
- The main advantages of shower chairs are the safety and comfort provided to users that are unable to remain in a standing position for extended amounts of time or that simply enjoy prolonged showers. Among these types of users are persons of limited mobility or strength, for instance, elderly users; arthritic users; users that have undergone surgeries; or users that are otherwise affected by various medical or age related conditions. Other users instead are healthy persons that enjoy long, warm showers for relief in cold climates or for general physical well-being.
- No shower chairs are available at present that are ergonomically designed to provide optimal interfaces with the user's body. In particular, no shower chairs are available today that offer both ergonomic design and, at the same time, a built in bidet through which the user can clean and soothe the perineal region of her body.
- Historically, shower chair designs have been dominated by utilitarian or aesthetic considerations. For instance, the seat and back portions of presently available shower chairs exhibit flat or U-shaped profiles, but not profiles that reflect body curvatures or that provide optimal weight distribution on the spine of the user. Some of the presently available shower chairs have been disclosed in U.S. and international applications; among others, U.S. Pat. No. D355,985 by Karten et al., issued on Mar. 7, 1995, discloses an integrally molded, stackable shower chair where the seat and back portions exhibit a shallow U-shape.
- “Ergonomic” is a scientific term that relates to the interaction between humans and artifacts. Specifically, scientific research during the 20th century has shown that typical sitting postures reduce the static muscular efforts of legs and hips, but also increase physical loads on inter-vertebral discs, in particular in the lumbar (mid-back) region of the spine. Such scientific research is outlined in several articles and treatises, for instance, Gavriel Salvendy, Editor, HANDBOOK OF HUMAN FACTORS AND ERGONOMICS (John Wiley & Sons, 1997, 2nd ed.).
- Therefore, an ergonomic shower chair must contain features that minimize stress on the users' bodies while maximizing comfort, and at the same time must exhibit design and construction features that are suitable for a shower environment.
- The use of bidets for personal hygiene has also become increasing popular. In particular, a number of inventions have been disclosed recently that involve bathroom fixtures including bidet attachments.
- U.S. Pat. No. 5,581,825“Bidet Shower Seat” by Honsvald, issued on Dec. 10, 1996, discloses a stool upon which a user can seat or which can be positioned under a support chair, and which includes nozzles on its upper surface directing water onto the genital region of the user. This stool has no specific ergonomic features, and includes an interior bowl mounted on the outer body and a number of spray nozzles positioned in the forward and rearward portions of such interior bowl. Water is supplied by attaching a conduit (such as a hose) to a valve and the discharge water is drained through an opening in the central part of the interior bowl.
- U.S. Pat. No. 6,226,810“Portable Bath Seat” by Weddendorf et al., dated May 8, 2001, discloses instead a platform supported by and clamped to the sidewalls of a bathtub, on which a seat is slideably carried. In one embodiment, this seat may include a bidet attachment essentially consisting of a perforated tube which is snapped into an opening on the seat. Water flows into such tube through a valve connected to a conduit such as a hose and is then drained through holes in the seat.
- In summary, prior art does not include a shower chair designed to meet the ergonomic requirements of the user. In addition, the supply of water into any optional bidets is laborious and requires auxiliary water supply devices, such as a hose.
- One of the objects of the present invention is an ergonomic shower chair that provides the user with optimal comfort and convenience by matching the shapes and characteristics of such chair with the physical shapes and load distributions of a typical user, and that incorporates ergonomic features aimed at reducing spinal disc pressure and at improving blood circulation to the thighs and feet.
- Another object of the present invention is an ergonomic shower chair with a bidet function that is comfortable, effective, and that does not require any specific attachments or set-ups beyond the availability of a typical hand-held showerhead.
- Additional advantages and novel features of the invention will be described in part in the description that follows and may be realized and attained by means of the individual design and manufacturing features and by combinations thereof.
- According to the present invention, the foregoing and other advantages and features are attained by a shower chair that comprises an ergonomic seat portion, an ergonomic back portion and a bidet portion, which is activated by holding a hand-held shower head against the main opening of such bidet portion.
- The seat portion of the present invention is designed to reduce loads on the spine of a seated user, particularly in the lumbar section, and at improving blood circulation in the thighs and feet. Accordingly, the upper surface of the seat portion exhibits double curvatures, with an overall curved surface that includes concave, shallow cavities corresponding to the user's buttocks. This design maintains the user safely into position, but at the same time allows the user to sit comfortably with some “wiggle” room, without being pushed toward the center of the seat.
- A longitudinal perineal groove is located in the central part of the seat portion and houses a series of holes, from which water is discharged from bidet nozzles positioned coaxially within such holes, and at the same time water is drained in the interstices between the bidet nozzles and the inner diameters of such holes. This groove extends to the area corresponding to the coccyx (or “tailbone”) of the user for maximum comfort.
- The front edge of the seat portion extends forward in a curved, “waterfall” shape, in order to reduce pressure on the underside of the thighs and to facilitate blood flow to legs and feet. Anatomically-contoured hand grips are also carved in each side of the seat, as well as recesses to rest the hand-held showerhead when not in use.
- In one embodiment, the seat portion has a hollow structure, with supporting columns positioned longitudinally in the central area, in order to provide rigidity but also produce an effect under the user's buttocks similar to that of a padded seat, further reducing pressure on the user's spinal discs. Handgrips, and showerhead holders to rest the hand-held showerhead when not in use, are optionally included in the seat portion.
- The back portion exhibits a front surface with double curvatures, to provide an ergonomic contour corresponding to that of a human back and at the same time relieve disc pressure by re-establishing lumbar curvature. The front surface of the back portion is slightly inclined backwards, in order to transfer some of the user's weight against the backrest, further reducing inter-vertebral disc pressure. A spinal groove runs longitudinally in the central area, in order to accommodate user's spine.
- In one embodiment, the back portion also has a hollow structure, which compresses slightly to provide a comfort level similar to that of a padded chair. Optionally, an anatomically contoured handle is also included in the back portion.
- The bidet portion comprises a main body of tubular form with an elliptical cross-section and a main opening of conical shape. Discharge nozzles protrude from the main body of the bidet portion and are coaxially inserted in some of the drain holes in the seat portion, causing a water spray in the user's perineal area.
- Water enters the bidet portion from a hand-held showerhead, held by the user against the main bidet opening. A rubber gasket covers such main opening, in order to eliminate water loss and to relieve pressure on the user's hand. Different embodiments of the present invention include means for affixing the hand-held showerhead to the main opening of the bidet portion, or for affixing the hand-held showerhead to the seat portion while the showerhead discharges water into the bidet portion, thereby freeing the hands of the user while water is being sprayed onto the user's perineal area.
- The back portion and the seat portion are connected by backrest pipes.
- In one embodiment, the ergonomic shower chair with built in bidet comprises means for adjusting the height of the back portion.
- In another embodiment, the present invention includes legs that are telescopically extendable.
- In still another embodiment, the ergonomic shower chair includes a bidet portion discharging water both from the seat and from the back portions of the chair.
- In another different embodiment, the ergonomic shower chair has no bidet portion.
