DETAILED DESCRIPTION

In some embodiments, the present disclosure describes a door for a walk-in bath that is manufactured via an injection process, such as injection molding. The method of manufacturing a door may be selected to allow for tighter tolerances and/or more detailed internal features than traditional manufacturing methods. The time, material, and/or labor necessary to manufacture the door by injection molding may be less than traditional manufacturing methods. In some embodiments, the door may include internal reinforcing ribs. A door may comprise a plurality of pieces that are joined together. A door may be lighter in weight than existing doors. A door may be manufactured such that the door is lighter than existing doors without loss in thermodynamic performance compared to existing doors. A door may be manufactured to reduce the number of anchors (e.g., threaded connectors, rivets) used to couple the door to other components compared to existing manufacturing methods. Some components (e.g., a strike plate, a hinge) may be molded into the door. A door may include a fin on a top end thereof, which fin may be engageable by a user (a bather) to provide a handrail. The fin may be part of a ridge that extends around a portion of the perimeter of a tub.

FIG. 1 and FIG. 2 show a walk-in bath 10, according to an embodiment, with door 12 in a closed and open position, respectively. Walk-in bath 10 includes sidewall 11. Sidewall 11 and closed door 12 define a tub configured to contain water for a user (bather) to bathe in. Headrest 13 is part of ridge 14 which extends around a portion of an upper edge of sidewall 11. One or more panels 15 are supported by base 16. Fin 17 forms a continuous surface with ridge 14 with door 12 in a closed position. Gasket 18 on door 12 is visible in FIG. 2.

In some embodiments, the walk-in bath may include a panel coupled to the front of the frame, the front and one of the left side or right side of the frame, the front, left side, and the right side of the frame, or all four sides of the frame. The frame may be coupled to a base. In some embodiments, a base may have a larger footprint than a frame. In other embodiments, a base and frame may have a similar or a same footprint.

In some embodiments, a walk-in bath may include a headrest. A headrest may be detachably coupled to an upper surface of a walk-in bath. A headrest may be part of a ridge that extends around at least a part of the tub. A headrest may be aligned with an upper surface of a ridge such that the headrest and ridge form a continuous surface. The ridge may taper along its length such that the headrest is at the apex of the ridge. At least one end of a ridge may be coplanar with an upper surface of the walk-in bath. A ridge may have a ridge width that is less than an upper surface width. A ridge may extend around about 100%, about 90%, about 80%, about 70%, about 60%, about 50%, about 40%, about 30%, or about 20% of a sidewall.

A sidewall may include an opening for a bather to enter and exit the walk-in bath. An opening may have an asymmetrical shape (e.g., an asymmetrical V-shape). An opening may be defined by a first side edge, a second side edge and a bottom edge. A bottom edge may be a threshold that is close to a bottom surface of the tub. A bottom edge may be generally parallel to a base or a ground surface. A first side edge may be disposed at an angle of about 90°, about 100°, about 110°, or about 120° relative to a bottom edge. A second side edge may be disposed at an angle of about 80°, about 90°, about 100°, about 110°, about 120°, about 130°, about 140°, or about 150° relative to a bottom edge. In one embodiment, a first side edge is disposed at an angle of about 91° relative to a bottom edge and a second side edge is disposed at an angle of about 97° relative to the bottom edge. In some embodiments, a second side edge may be stepped with a lower part of the edge at a first angle relative to the bottom edge (e.g., about 90 degrees to about 95 degrees) followed by a substantially horizontal section and a second upper portion of the second edge at a second angle relative to the bottom edge (e.g., about 90 degrees to about 95 degrees).

In some embodiments, a walk-in bath may include a door configured to move (e.g., rotate or slide) relative to a sidewall or opening between a closed position and an open position. A door may be moveably coupled to a sidewall via a hinge such as a piano hinge. A door may form a watertight seal with a first side edge, a second side edge, and a bottom edge when the door is in the closed position. A door may include an outer surface configured to be aligned (e.g., co-planar) with an outer surface of the walk-in bath when the door is in the closed position. A door may have an asymmetrical shape corresponding to that of an opening defined above. In some embodiments, a door may have an asymmetrical V-shape.

In some embodiments, a door may include a fin. A fin may extend from an upper surface of the door. In some embodiments, a fin can be manually engaged by a bather such that the fin can be used as a handle to open or close the door. A bather may grasp a fin to brace themselves as they move between sitting and standing positions or as the bather enters or exits the tub. In some embodiments, a fin may have a similar cross-sectional shape and/or profile as a ridge. In some embodiments, a fin and ridge may form an uninterrupted surface. A portion of a fin may have a cross-sectional shape defined by an arc segment of a circle. In one embodiment, a cross-sectional fin shape may have a cross-sectional radius of about 0.25 inches, about 0.5 inches, about 0.65 inches, about 0.75 inches, about 1 inch, about 1.25 inches, about 1.5 inches, about 1.75 inches, or about 2 inches. In some embodiments, an outer perimeter of a fin comprises a concave portion configured for a bather to grasp the fin. In one embodiment, an outer perimeter has an outer perimeter radius of about 0.1 inches, about 0.25 inches, about 0.4 inches, about 0.5 inches, about 0.75 inches, about 1 inch, about 1.25 inches, about 1.5 inches, about 1.75 inches, or about 2 inches.

In some embodiments, a fin may extend above an upper surface of a door. A fin may have a maximum height of about 0.5 inches, about 1 inch, about 1.25 inches, about 1.5 inches, about 2 inches, about 2.5 inches, about 3 inches, about 3.5 inches, or about 4 inches. A fin may have a maximum height at a first end of a door. A fin may be flush with an upper surface on a second end of the door. A fin may taper from a maximum height at the first end to a minimum height at the second end. A fin may have a maximum width at a door first end.

A fin width may be less than the width of the door. At least one side of the fin may be generally parallel with a side of the door.

A door may include an edge surface extending around at least a portion of the door. An edge surface may extend around at least one of the left side, right side, and bottom of the door. An edge surface may be configured to engage an inner surface of a sidewall and/or opening first side edge, second side edge, and/or bottom edge. A channel may be positioned on a door edge surface and the channel may be configured to receive a gasket. At least one of an opening first side edge, second side edge, and/or bottom edge may have an inverse shape to an edge surface to increase the surface area where the door engages the sidewall. An edge may comprise an angled edge surface.

In some embodiments, a door edge surface configured to engage with and form a seal with a sidewall may be angled; that is to say, a seal surface formed by a door and a sidewall may be angled as illustrated in FIG. 5 and FIG. 9. In some embodiments, a door edge surface angle may be from any of about 35°, about 36°, about 37°, about 38°, about 39°, or about 40°, to any of about 41°, about 42°, about 43°, about 44°, about 45°, about 46°, about 47°, about 48°, about 49°, about 50°, about 51°, about 52°, or more. In some embodiments, both a left side door edge and right side door edge comprise an angled surface. In other embodiments, only a left side door edge or a right side door edge comprise an angled surface. In some embodiments, a left side door edge, a right side door edge, and/or a bottom door edge may comprise angled surfaces. A left side door edge, right side door edge, and bottom door edge may comprise same or different angled surfaces.

According to this disclosure, an angled door edge surface is one that differs from a substantially 90° angle between a door edge and a door face. A typical door of a home therefore comprises door edge surfaces that are not angled. Thus, a door edge surface having an angle of greater than or less than about 90° is considered “angled”.

In some embodiments, a door channel configured to receive a gasket is disposed in a door angled edge surface. In some embodiments, a door edge surface may comprise both an angled portion and a non-angled portion.

In some embodiments, a door may be a unitary construct. In other embodiments, a door may include a first piece and a second piece. A first piece may be coupled to a second piece with one or more adhesives, welding (e.g., ultrasonic welding), rivets, or threaded connectors. A first piece and second piece may be manufactured by injection molding or gas assist injection molding. Injection molding manufacturing methods may cut down on fabrication time and provide molded-in features configured to secure at least one of a hinge, strike plate, or gasket.

In some embodiments, a first piece may include one or more ribs (e.g., reinforcing ribs). In some embodiments, ribs are evenly and/or symmetrically positioned about a first piece. In other embodiments, ribs are selectively positioned about a first piece to strengthen areas that may be subject to increased stress loads. In some embodiments, a first piece includes a higher concentration of ribs corresponding to the location of a strike plate than other locations. In some embodiments, a first piece includes a higher concentration of ribs corresponding to the location of a hinge that couples a door to a sidewall than other locations.

In some embodiments, a first piece may include one or more protrusions configured to be positioned in corresponding receivers in a second piece. Protrusions and receivers may assist in aligning a first piece and second piece during assembly of the door. Protrusions may include a recess configured to receive a connector (e.g., dowel, rivet, or threaded connector) to couple a first piece to a second piece.

In some embodiments, a second piece may include one or more ribs. A location of at least one rib of a second piece may be to align with a rib on a first piece such that the ribs engage each other and provide a continuous structure through a door body. Ribs on a first piece may interlock with ribs on a second piece. In some embodiments, each rib on a second piece align with a rib on a first piece. In some embodiments, a second piece includes more ribs than a first piece. In some embodiments, a second piece includes less ribs than a first piece.

In some embodiments, a door may include one or more cavities between a first piece, a second piece, and ribs. The cavities may be filled with foam or insulation. In some embodiments, the cavities may comprise a volume of about 50%, about 60%, about 70%, about 80%, or about 90% of a total volume of a door.

In some embodiments, a perimeter of at least one of a first piece and a second piece may be recessed from an adjacent surface such that a groove extends around at least a portion of a door. A groove may have a width of about 0.01 inches, about 0.02 inches, about 0.03 inches, about 0.04 inches, about 0.05 inches, about 0.06 inches, about 0.07 inches, about 0.1 inch, about 0.15 inches, about 0.25 inches, or about 0.5 inches. A groove may have a depth of about 0.01 inches, about 0.02 inches, about 0.03 inches, about 0.04 inches, about 0.05 inches, about 0.06 inches, about 0.07 inches, about 0.1 inch, about 0.15 inches, about 0.25 inches, or about 0.5 inches. A groove may be filled with a color matching adhesive (e.g., colored epoxy). An adhesive may be buffed and polished to match the appearance of a door. A coat of paint (e.g., spray paint) may be applied to the buffed and polished adhesive. A coat of paint on the adhesive may then be buffed and a finish coat (e.g., clear coat) may be applied. A finish coat may then be buffed. In some embodiments, an entire door including the adhesive may be painted to present a uniform appearance.

In some embodiments, a door may include a strike plate configured to engage a handle of the walk-in bath to maintain the door in a closed position. In some embodiments, the strike plate is molded into a door second piece. In other embodiments, a strike plate may be coupled to a second piece via one or more adhesives, welding, rivets, threaded fastener or other mechanical fastener. A strike plate may have an engagement surface such that as the handle moves relative to the strike plate, the door is moved into the fully closed position. At least a portion of an engagement surface may be defined by an arcuate segment having a radius of about 30 mm to about 300 mm. An engagement surface may be defined by a spline shape (e.g., a plurality of arcs connected to each other to form a continuous shape) having radii that vary from about 30 mm to about 300 mm. In some embodiments, an engagement surface may have a convex section and a concave section, with the convex section above the concave section.

In some embodiments, a handle may include an insert configured to engage an engagement surface of a strike plate. An insert may be manufactured from a material that is more durable than other portions of the handle. In some embodiments, an insert may comprise one or more of high density polyethylene (HDPE), aluminum, acetal polyoxymethylene (POM), or stainless steel. An insert may be coupled to a handle via one or more of anchors, welding, adhesive, or rivets. An insert may be detachably coupled to a handle such that the insert is replaceable. A handle may be rotatable about an axis to engage and disengage an engagement surface to allow the door to move between closed and open positions.

In some embodiments, a gasket may be provided to help create a watertight seal between a door and a sidewall (e.g., a tub inset flange on a sidewall) around the perimeter of the opening. An anchor section of a gasket may be received in a channel of a door. In some embodiments, a gasket anchor section may include one or more barbs configured to secure the gasket within the channel. A gasket may be detachably coupled to a door. A gasket may include a body configured to be positioned outside of a channel such that the body engages a sidewall when the door is in the closed position. A gasket having an anchor section disposed in a channel and a gasket body outside the channel is considered to be disposed in the channel. A gasket body may be configured to elastically deform to occupy a space between a sidewall and door to create a watertight seal when the door is in the closed position. A gasket body may be manufactured from a first material and a gasket anchor section may be manufactured from a second material different from the first material. Alternatively, a gasket body and anchor section may comprise same or similar materials. In some embodiments, a gasket body section may be hollow.

In some embodiments, a door channel configured to receive a gasket may comprise a shape configured to receive and mate with a gasket anchor section. In some embodiments, a door channel may comprise one or more slots configured to receive a gasket anchor section. In some embodiments, a door channel may comprise barb-shaped portions configured to receive and mate with barbs of a gasket anchor section.

In some embodiments, a channel may have a reduced width portion compared to an adjacent portion. A channel reduced width portion may enhance the purchase or mating between a gasket anchor section and a door.

In some embodiments, a handle may include a base. In some embodiments, a handle base is fixed to a sidewall via an anchor. In other embodiments, a base is fixed to a sidewall via one or more of an adhesive, welding, or rivet. A base may include a threaded portion configured to engage a threaded portion on the handle. A threaded engagement between a handle and a base may allow the handle to be rotated a first amount (e.g., about 360°) relative to the base to advance toward the sidewall. An insert and/or a gasket may flatten or wear down over time. In some embodiments, a handle may be rotated to an additional amount (e.g., about) 360° relative to the base to advance the handle further toward the sidewall to maintain the seal between the door and the sidewall even when a gasket flattens or an insert wears down. A base may include a recess configured to receive a limiter. A limiter may limit the rotation of the handle relative to the base.

In some embodiments, a door may comprise a cap that may couple to a door first piece and a door second piece. A cap may comprise a fin. A door first piece and/or a door second piece may include a flange configured to be received by the cap. A flange may be configured to deflect as it is received by the cap such that the flange forms a friction fit or snap fit with the cap. A cap may be coupled to a first piece and/or a second piece via one or more adhesives, weld, or mechanical fastener. In some embodiments, a cap may be detachably coupled to a door first piece and/or second piece.

In another embodiment, a door may comprise a first piece and/or a second piece having a flange. A flange may be configured to be received by a gasket. The gasket may be configured to provide a seal between the door and a sidewall. The gasket may be deformable to conform to the size and shape of a space between the flange and the sidewall. The flange may comprise a first portion and a second portion, wherein the first portion may be transverse to the second portion. The second portion may comprise a male connector configured to be received by a gasket female connector. The gasket may be coupled to the flange via one or more adhesives, friction fit, or snap fit.
