Description

FIELD OF THE INVENTION

The present inventions relate to a lavatory system. The present inventions more specifically relate to a lavatory system including a toilet with a cover movable between a stowed position and a deployed position.

BACKGROUND

It is generally known to provide for a lavatory system for use in a home, commercial or institutional facility such as a medical care facility or the like. Known arrangements for lavatory systems may provide (in a compact design) a base (e.g., cabinet), a sink, water closet (i.e., with toilet), countertop, and may be configured with one or more accessories such as a bedpan washer, dialysis equipment, etc. Such lavatory systems may be configured to provide a movable cover for a toilet that (relative to the base) can be deployed to cover the toilet (and provide a seat) or lifted to stow the cover and allow access to (or use of) the toilet. However, such known arrangements for lavatory systems may present inconvenient or disadvantageous features in application or use, such as relative difficulty to use (e.g., effort and vigilance to stow or cover toilet), or to clean (or keep clean), or to maintain. Also, such known arrangements may present inconvenient or undesireable operation such as high impact or velocity deployment of the cover if the cover is dropped onto the toilet, which may cause a potential for an unpleasant or startling noise, or for damage to the cover, linkage, or toilet.

Accordingly, it would be advantageous to provide a lavatory system that has a compact design and a movable cover for the toilet. It would also be advantageous to provide a lavatory system with a mechanism for moving the cover relative to the base that is more convenient to use. It would further be advantageous to provide a lavatory system that is configured to control the velocity that the cover can be raised and/or lowered. It would further be advantageous to provide a lavatory system that is configured to be more convenient to clean, keep clean, and maintain. It would be desirable to provide for a lavatory system having one or more of these or other advantageous features.

SUMMARY OF THE INVENTION

Cover 222 provides a lid to cover the upper portion of the commode 204. Cover 222 also provides a surface for seating (e.g., a seat or seating surface) or for temporarily placing an object. The cover may be shaped and configured and otherwise adapted for any commode or receptacle. Backrest 220 provides support for the user to lean against when seated on the cover 222.

Cover 222 and backrest 220 are configured to move between a deployed or use position (see FIGS. 1, 3, 4, 6, and 9) and a retracted or stowed position (see FIGS. 2, 5, 8 and 9) relative to commode 204 and/or frame 210. In the deployed position, cover 222 is generally horizontal and backrest 220 is generally vertical. In the stowed position, both cover 222 and backrest 220 are generally vertical and retracted within cabinet 202. According to an alternative embodiment, the cover and backrest may have any of a variety of positions, configurations, or orientations when in the stowed position, deployed position, or therebetween.

According to a preferred embodiment shown in FIGS. 3-9, members 224 are configured to transfer “lifting” movement of cover 222 (e.g., pivoting) to “stowing” movement of backrest 220 (e.g., translation). One end of each member 224 is pivotally coupled to an edge of cover 222. The other end of member 224 is coupled to an edge of backrest 220. According to a particularly preferred embodiment, cover 222 and backrest 220 are configured to for both pivoting and translating movement. According to alternative embodiments, the cover and the backrest may be configured for a variety of pivoting, translating, articulating, actuating, constrained, restricted, guided, etc. movement, and in a variety of other paths of travel relative to the commode.

According to a particularly preferred embodiment shown in FIG. 12, members 224 are coupled cover 222 by a fastener member 292 (e.g., a screw) engaging a nut 294 located within a recess of apron 236. According to a particularly preferred embodiment, fastener member 292 is welded to member 224. According to a particularly preferred embodiment, a washer 296 is located between member 224 and apron 236, a washer 298 is located between a shoulder of the recess in apron 236 and nut, and a bushing 300 supports fastener member 292 in a bore. The washers and/or bushing may be plastic, metal, fiber, or the like. According to a particularly preferred embodiment, a cap or plug 302 is coupled to apron 236 to cover the recess.

According to an exemplary embodiment, members 224 are spaced between approximately 3 inches and approximately 7 inches between pivot points and disposed (i.e., extend relative to each other) at an angle of between approximately 10 degrees and approximately 60 degrees (from horizontal). According to an exemplary embodiment, members 224 are spaced between approximately 4 inches and approximately 6 inches between pivot points and disposed (i.e., extend relative to each other) at an angle of between approximately 20 degrees and approximately 40 degrees (from horizontal). According to a preferred embodiment, members 224 are spaced between approximately 4.5 inches and approximately 5.5 inches between pivot points and disposed at an angle of between approximately 24 degrees and approximately 30 degrees (from horizontal). According to a particularly preferred embodiment, members are spaced approximately 4.8 inches and approximately 5.2 inches between pivot points and disposed at an angle between approximately 25 degrees and approximately 29 degrees (from horizontal). According to an alternative embodiment, the members may be configured or spaced in a variety of sizes or dimensions and be orientated or disposed at a variety of angles to transfer the movement between the cover and the backrest.

According to a preferred embodiment, when cover 222 is in the generally vertical position, members 224 are configured to be in a generally horizontal position (see FIG. 9). According to alternative embodiments, the backrest and cover assembly may include a plurality of members (e.g., multi-bar or other linkages) configured to move the backrest to the stowed position and/or to prohibit pivoting of backrest 220 past a desired position (e.g., generally vertical) if pressure is applied (e.g., as when being rested or leaned against by a user).

Referring to FIGS. 3-8, a pair of support brackets 229 are mounted to backrest 220 and are configured to limit pivotal movement of backrest 220. According to an exemplary embodiment, the pivotal movement is prevented or restricted so that when a lateral force is being exerted upon backrest 220 (e.g., from someone sitting on cover 222 and leaning on backrest 220), movement of backrest 220 toward the interior of cabinet 202 is restricted or prevented. According to a preferred embodiment, each support bracket 229 is provided as an independent structure from members 224 and is mounted to backrest 220 (instead of to cover 222, as may be done according to alternative embodiments). According to a preferred embodiment, support brackets 229 are mounted to a rear surface 230 of backrest 220 and have lower portions 232 that extend below backrest 220 and adjacent or proximate to ends 234 of an apron 236 of cover 222 when cover 222 and backrest 220 are in the deployed position (i.e., approximately 90 degrees from each other). Pivotal movement of cover 222 beyond this position is restricted or prevented by the interference or contact between lower portions 232 and the ends 234 of cover 222. According to alternative embodiments, the support brackets may be configured to limit pivotal movement to any of a variety of angles between the backrest and the cover.

According to an exemplary embodiment shown in FIGS. 3-8, mechanism 228 affects the movement of backrest 220 and cover 222 between the deployed positions (see FIGS. 1, 3, 4, 6, and 9) and the stowed positions (see FIGS. 2, 5, 8, and 9). For example, mechanism 228 may be configured to control, assist, guide, resist, or the like the movement of backrest 220 and cover 222 between the deployed positions and the stowed positions. According to a preferred embodiment, mechanism 228 is configured to control or dampen the movement or velocity of cover 222 as it is being moved between its stowed and deployed positions. Controlling or dampening the movement or velocity of cover 222 is intended to avoid impact noise and potential damage to components such as cover 222, frame 210, cabinet 202, backrest 220, and the like (e.g., if a user accidentally or prematurely releases cover 222). Mechanism 228 includes an arm 226 (i.e., pivot arm), a motion dampening device shown as a damper 248, a biasing member (shown as a spring 250), and a follower assembly 252.

Arm 226 includes a first portion 238 coupled to cover 222 and a second portion 240 coupled to cabinet 202 (e.g., via damper 248). According to an exemplary embodiment, second portion 240 extends from first portion 238 at an angle. According to a preferred embodiment shown in FIG. 4, second portion 240 projects or extends upward relative to first portion 238. According to an exemplary embodiment, second portion extends relative to first portion 238 between an angle of between approximately 110 degrees and approximately 125 degrees. According to a particularly preferred embodiment, second portion 240 extends upward at an angle of between approximately 118 degrees angle relative to first portion 238. According to alternative embodiments, the second portion may extend at any of a variety of angles (or linearly or parallel) relative to the first portion. Cover 222 and first portion 238 is coupled to frame 210 by a pivot shaft 242 (e.g., a bolt, pin, etc.). According to a preferred embodiment shown in FIG. 13, pivot shafts 242 are coupled to frame 210. Referring again to FIG. 4, second portion 240 is coupled to a pivot rod or shaft 244. First portion 238 is angled relative to second portion 240 for example, to provide clearance for one of a pair of support brackets 229 mounted on rear surface 230 of backrest 220. According to a particularly preferred embodiment, the linkage is made from rigid, corrosive-resistant materials (e.g., stainless steel), but may be made from any of a variety metals, plastics, or other suitable materials. According to an alternative embodiment, the mechanism or damper is coupled to the backrest and is configured to control and/or guide movement of the cover (and/or the backrest) by controlling and/or guiding the movement of the backrest.

Damper 248 is configured to provide an impedance or resistance to movement of cover 222 to control the velocity of movement of cover 222. When cover 222 is being moved (e.g., towards the stowed portion and/or towards the deployed position), damper 248 provides a resisting or impeding force. According to a preferred embodiment, damper 248 also provides a biasing force (e.g., a return force) that biases cover 222 in the stowed position (e.g., to assist in the movement of cover 222 towards the stowed position and to counteract a torque force due to the weight of cover 222). An applied force from damper 248 increases to approach the force of the input load (which is provided by the user lifting or lowering cover 222). The applied force approaches a zero-net force, resulting in zero acceleration and a constant velocity which is preferably limited to a desired value. (As such, the applied force is configured to counter-balance the torque created by movement of cover 222.) One end 254 of damper 248 is coupled to pivot shaft 244 and the other end 256 coupled to cabinet 202 by another pivot shaft or rod.

According to a preferred embodiment, damper 248 is a gas or pneumatic spring that provides a constant impedance or resistance to movement of cover 222 and is biased to its extended position. According to an exemplary embodiment, damper 248 provides a varying impedance or resistance to movement of cover 222. According to a particularly preferred embodiment, the damper is of a type commercially available as “Camloc” (Model No. SWY85825030958D) from Arvin Motion Control of Leicester, England. According to alternative embodiments, the damper may be any of a variety of air, gas, liquid, elastomer, spring, or hydraulic devices, shocks, or shock absorber, dashpot mechanisms, air spring, cylinders, actuators that dampen or resist motion or combinations thereof. According to further alternative embodiments, the damper provides a variable impedance or resistance (e.g., an increasing or decreasing amount of impedance, a partial dampening stroke, and the like).

Biasing member (shown as spring 250) biases cover 222 to a position approximately midway between the deployed and stowed positions (e.g., approximately 45 degrees). Spring 250 is coupled at one end to pivot shaft 244, and at the other end to a shaft 246 extending from cabinet 202. Spring 250 biases cover 222 so that an opposing force is exerted on cover 222 when moved near the stowed or deployed position (e.g., to assist the user in starting the movement of cover 222, and prevent a large acceleration of cover 222 into the stowed position). As cover 222 is moved towards the stowed position, the torque force due to the weight (moment) of cover 222 decreases and may become less than the biasing or return force provided by damper 248. As such, spring 250 is configured to compensate for (e.g., counterbalance) the reduced torque force to prevent or restrict cover 222 from undesired movement or from moving the remainder of the distance to the stowed position at an undesired rate of speed. According to an alternative embodiment, the spring is configured to affect movement of the cover at or near either the stowed or the deployed positions, during all or substantially all of the range of movement of the cover, or other ranges of movement or relative positions of the cover and/or the backrest. According to an alternative embodiment, the spring is positioned, selected spring constant, sized, etc. to affect movement of the cover at or near either the stowed or the deployed positions, during all or substantially all of the range of movement of the cover, or other ranges of movement or relative positions of the cover and/or the backrest

Referring to FIGS. 3 and 9, follower assembly 252 is configured to support backrest 220 and maintain backrest 220 in a generally vertical position when in the deployed or stowed positions. According to a preferred embodiment, follower assembly 252 is mounted at both sides of backrest 220. Each follower assembly 252 includes a shaft 260 that is supported by and slides along a pair of guide rods 262 (e.g., cam, track, bracket, arm, etc.). Shaft 260 extends from a pair of brackets 264 mounted to rear surface 230 of backrest 220. Guide rods 262 are attached to the frame 210 and provide a sliding bearing surface for shafts 260. Guide rods 262 are sloped generally downward so that the backrest 220 moves downward relative to countertop 206 when moving to the stowed position. As cover 222 is moved between the deployed and stowed positions, shafts 260 slide along guide rods 262. According to alternative embodiments, the follower assembly may be any of a variety of mechanisms. For example, the follower assembly may be any of a variety of followers, follower mechanisms, guide mechanisms or assemblies, track mechanisms or assemblies, or the like.

Movement or actuation of cover 222 is initiated by the user lifting cover 222 from its deployed position and moving it towards its stowed position. As cover 222 begins to move, it pivots relative to backrest 220 (abuts ends of members 224). Pivoting of members 224 causes backrest 220 to move towards the interior of the cabinet. As such, follower assembly 252 works to maintain backrest 220 in a generally vertical orientation by shafts 260 sliding along guide rods 262.

FIG. 9 shows backrest and cover assembly 208 during use. As cover 222 is rotated, members 224 rotate about their ends (attached to cover 222 and backrest 220) to move (e.g., pivot and/or translate) backrest 220 between the deployed and stowed positions. As cover 222 is pivoted, pivot arm 226 moves pivot shaft 244 and actuates damper 248, which impedes movement of cover 222. Mechanism 228 is configured to control or dampen the movement or velocity of cover 222 as it is being moved between its stowed and deployed positions. Controlling or dampening the movement or velocity of cover 222 is intended to avoid impact noise and potential damage to components. Also, shafts 260 slide along guide rods 262 as backrest 220 actuates.

Referring to FIGS. 1, 4, and 9, a barrier 266 is mounted at the interface of cover 222 and backrest 220 and is configured to cover the gap between cover 222 and backrest 220. Barrier 266 includes a panel 268 coupled to backrest 220 by a hinge 270. Panel 268 may be rigid, semirigid, flexible, plastic, cloth, metal, a web, movable with cover and/or backrest, removable and/or replaceable (e.g., if becomes wet, soiled or the like), etc. Hinge 270 may be provided in any of a variety of configurations such as hinge designs, including a barrel hinge (as shown), a flexible member, a rigid member (flexibly coupled), or the like.

According to a preferred embodiment shown in FIGS. 10 and 11, a backrest pad 280 is removably attached to backrest 220 (e.g., for cleaning, replacement, removal, etc.). FIG. 10 is a perspective view of lavatory system 200 with removable backrest pad 280 and FIG. 11 is a perspective view of lavatory system 200 with backrest pad 280 exploded off of backrest 220. According to a preferred embodiment, backrest pad 280 includes a bracket 282 mounted to the back (i.e., non-show) surface 284 of backrest pad 280. Bracket 282 includes apertures 286 that engage members 288 projecting from a surface 290 of backrest 220. According to a particularly preferred embodiment, apertures 286 are slots having a narrow portion (i.e., dimension) at one end and a wide portion, and members 288 include a head portion that passes through the wider portion but is dimensioned to not pass through the narrow portion. According to alternative embodiments, the apertures may be any of a variety of openings, holes, slots, grooves, notches, keyhole slots, or the like, and the members may be any of a variety of posts, screws, bolts, shoulder bolts, projections, or the like. To mount backrest pad 280 to backrest 220, members 288 are aligned and inserted through the wide portion of apertures 286 and backrest pad 280 is moved so that members 288 engage the narrow portion of apertures 286 (e.g., slid downward).

Referring to FIG. 14, countertop 206 is coupled to frame 210 or cabinet 202 by one or more brackets 272. According to a preferred embodiment, the bottom surface of countertop 206 includes one or more guides 274 (e.g., bosses, protrusions, bumps, etc.) that assist in the positioning of countertop 206 relative to brackets 272. Ends of guides 274 interface (e.g., engage, fit into, etc.) with apertures in brackets 272 to “locate” countertop 206. Fasteners 276 secure countertop 206 to frame 210 or cabinet 202 (e.g., threadably engage inserts 278).
