Abstract
Description
- This application claims priority to United States Provisional Patent Application No. 61/755,668, filed Jan. 23, 2013, entitled “Walk-In Tub Door Assembly” and U.S. Provisional Patent Application No. 61/756,698, filed Jan. 25, 2013, entitled “Walk-In Tub Door Assembly”, the disclosures of which are hereby incorporated by reference in their entirety.
- Field of the Invention
- The present disclosure relates generally to walk-in tubs. More particularly, the present disclosure relates to a walk-in tub door assembly and a latching and sealing mechanism for use with the walk-in tub door assembly.
- Description of the Related Art
- Walk-in tubs generally have a tub portion with at least one doorway provided on a side of the tub. The doorway may be closed by a door that swings either into the interior of the tub portion or away from the side of the tub. In an open position, the door enables a user to walk into the tub without having to step over the side of the tub, which is the case with conventional tubs. In a closed position, the door encloses the tub portion so that it may be filled with water. A seal is provided at an interface between the door and the doorway to prevent water from leaking through the doorway when the tub portion is filled with water.
- In order to facilitate ingress to the tub and egress from the tub, as well as to provide a seal for preventing water from escaping from the tub, a variety of walk-in tub door designs have been developed. United States Patent Application Publication No. 2010/0156120 to Luo discloses a walk-in tub having a waterproof door and a sealing mechanism. The tub includes a frame having a door jamb. A door is hingedly attached to the door jamb and a handle is rotatably mounted to the door for selectively activating and deactivating a locking mechanism having a sliding pin. In one position, the pin is retracted within the door to allow the door to be swung open for easy access to the tub. In a second position, the pin is extended into an opening on the door jamb for locking the door in a closed position. A compressible gasket is provided on the door to seal the door against the tub. The door is adapted for opening away from the tub interior. This design complicates the sealing between the tub and the door because the water inside the tub has the tendency to push the door away from the sealed position.
- U.S. Pat. No. 4,360,935 to Barrett, Sr. discloses a deep bathtub with a side entrance door. The entrance door is supported on the bathtub and is slidable to allow ingress and egress to and from the bathtub.

In a closed position, thedoor 140 is pressed against the sealingface 130 of thedoor frame 120 to create a watertight connection and prevent water from leaking from theinterior cavity 60 of thetub 10. Rotating thedoor 140 to the open position moves thedoor 140 away from the sealingface 130 and into theinterior cavity 60 of thetub 10. In the open position, a user may enter thetub 10 through thedoor frame 120. - With reference to
FIGS. 7 and 8 , and with continuing reference toFIGS. 3 and 4 , thedoor 140 is mounted to thedoor frame 120 with ahinge 150. One part of thehinge 150 is fixed to thedoor 140 and the other part is fixed to thedoor frame 120 to permit thedoor 140 to swing between the open position and the closed position.Bolts 160, or other fasteners, may be used to secure thehinge 150 to thedoor frame 120 and thedoor 140. Thedoor 140 further includes aseal 170 disposed around a perimeter of thedoor 140 for sealing thedoor 140 against the sealingface 130 when thedoor 140 is in the closed position. Theseal 170 is provided at the interface between thedoor 140 and the sealingface 130 such that theseal 170 is at least partially compressed between thedoor 140 and the sealingface 130 when thedoor 140 is in the closed position. The structure of theseal 170 will be described hereafter with reference toFIGS. 14A-14B . - With continuing reference to
FIGS. 7 and 8 , thedoor 140 includes afirst portion 180 and asecond portion 190 defining adoor cavity 200 therebetween. In one embodiment, thefirst portion 180 is provided on the side of thedoor 140 that faces theinterior cavity 60 of the tub, while thesecond portion 190 is provided on the side of thedoor 140 that faces the tub exterior. Thedoor 140, including thefirst portion 180 and thesecond portion 190, is desirably made from the same material as thetub 10. In one embodiment, thedoor 140 is made from acrylic. In other embodiments, thedoor 140 may be manufactured from fiberglass, metal, plastic, or any other suitable material. -
FIGS. 7 and 8 further illustrate alatching mechanism 240 operable between a latching position and an unlatching position. Thelatching mechanism 240 is operated to a latching position when thedoor 140 is in a closed position, thereby securing thedoor 140 against the sealingface 130 and preventing water from leaking from theinterior cavity 60. In an unlatching position, thelatching mechanism 240 unlocks thedoor 140 from the closed position, thereby permitting thedoor 140 to be moved to the open position. Thelatching mechanism 240 is operated by ahandle 250 provided on thefirst portion 180 or thesecond portion 190. In one embodiment, thehandle 250 may be provided on both thefirst portion 180 and thesecond portion 190 of thedoor 140. - Movement of the
handle 250 causes thelatching mechanism 240 to be operable between the latching position and the unlatching position. Thehandle 250 is rotatably connected to aplate 260 having a plurality ofrods 270 pivotally connected to theplate 260. Rotation of thehandle 250 causes theplate 260 to rotate such that the plurality ofrods 270 is moved in a linear manner. Therods 270 are connected to the plate byfasteners 280 that allow therods 270 to pivot about a connection point with theplate 260 without being disconnected therefrom. As shown inFIGS. 7 and 8 , one of therods 270 extends in a substantially vertical direction along a first axis while theother rod 270 extends in a substantially horizontal direction along a second axis. Therods 270 extend through thedoor 140 and are movable past the outside perimeter of thedoor 140. In one position, such as when thelatching mechanism 240 is in an unlatched position, therods 270 are withdrawn inside thedoor cavity 200 to permit thedoor 140 to open. In a second position, such as when thelatching mechanism 240 is operated to a latching position, therods 270 are moved to extend outside thedoor cavity 200 in order to lock thedoor 140 within thedoor frame 120. - With continuing reference to
FIGS. 7 and 8 , and with reference toFIGS. 9 and 10 ,rods 270 terminate in alatching pin 290 that is slidable in a linear manner with the movement of therods 270. The latchingpin 290 desirably has a tapered point 300 (shown inFIGS. 9 and 10 ). Whendoor 140 is moved to the closed position such that the sealingface 130 abuts the perimeter of thedoor 140, thedoor 140 may be locked in the closed position by operating thehandle 250 to move thelatching mechanism 240 in the latching position. Such movement of thelatching mechanism 240 causes therods 270 to move in a linear manner away from the interior of thedoor cavity 200. Movement of therods 270 causes thelatching pin 290 to extend outside thedoor 140 and to engage apin receiver 310 on thedoor frame 120. Thepin receiver 310 may be fastened to thedoor frame 120, or it may be molded into thedoor frame 120. Thepin receiver 310 includes acentral opening 320 sized to receive thelatching pin 290. Acorresponding pin guide 330 may be provided on thedoor 140 to guide thelatching pin 290 toward thepin receiver 310. - With reference to
FIGS. 9 and 10 , thetapered point 300 of the latchingpin 310 provides a mechanical advantage in closing thedoor 140 and maintaining thedoor 140 in the closed position. Thetapered point 300 guides the latchingpin 290 into thecentral opening 320 of thepin receiver 310, thereby urging thedoor 140 to the closed position and compressing theseal 170 between thedoor 140 and the sealingface 130 on thedoor frame 120. Thetapered point 300 is desirably shaped as to guide thelatching pin 290 into thecentral opening 320 of thepin receiver 310. - With reference to
FIG. 11 , alatching mechanism 400 is shown in accordance with a second embodiment. Thelatching mechanism 400 is operable between a latching position and an unlatching position. Thelatching mechanism 400 is operated to a latching position when thedoor 140 is in a closed position, thereby locking thedoor 140 against the sealingface 130 and preventing water from leaking from the interior cavity. In an unlatching position, thelatching mechanism 400 unlocks thedoor 140 from the closed position, thereby permitting thedoor 140 to be moved to the open position. Thelatching mechanism 400 is operated by ahandle 410 provided on an inside portion of thedoor 140. - Movement of the
handle 410 causes thelatching mechanism 400 to be operable between the latching position and the unlatching position. Thehandle 410 is rotatably connected to acam plate 420 having arod 430 pivotally connected to thecam plate 420. Rotation of thehandle 400 causes thecam plate 420 to rotate such that therod 430 is moved in a linear manner. In one position, such as when thelatching mechanism 400 is in an unlatched position, therod 430 is withdrawn inside thedoor cavity 200. In a second position, such as when thelatching mechanism 400 is operated to a latching position, therod 430 is moved to extend outside thedoor cavity 200. - With continuing reference to
FIG. 11 , thelatching mechanism 400 includes an upper latching assembly 440 (shown in greater detail inFIG. 12 ) and a lower latching assembly 450 (shown in greater detail inFIG. 13 ). Referring toFIG. 12 , theupper latching assembly 440 includes ahousing case 460 that is secured to thedoor 140. Thehousing case 460 supports abacking plate 470 and thecam plate 420 having anupper latching pin 480 secured thereon. Theupper latching pin 480 extends through anupper pin guide 490 of thehousing case 460. Handle 410 (shown inFIG. 111 ) is connected to ashaft 500 that is operatively connected to thecam plate 420 such that rotation of theshaft 500 causes a corresponding rotation of thecam plate 410. Aspring 510 provides a biasing force on thecam plate 420 to return thehandle 410 to its default position. Theupper latching pin 480 desirably has a taperedpoint 580 at its terminal end. Thetapered point 580 is desirably shaped as to guide thelatching pin 480 into the central opening of theupper pin guide 490. - Referring to
FIG. 13 , thelower latching assembly 450 includes abottom bracket assembly 520 that is secured to the inside portion of thedoor 140. The lower portion of the rod 430 (shown inFIG. 11 ) is connected to alower latching pin 530 by afastener 540. Thelower latching pin 530 is disposed within thebottom bracket assembly 520 and is movable relative to a lower pin guide 550. Thelower latching assembly 450 further includes aroll pin 560 extending through thelower latching pin 530 to engage alower spring 570 when thelower latching pin 530 is extended to a latching position. Thelower latching pin 530 desirably has a taperedpoint 590 at its terminal end. - When
door 140 is moved to the closed position, thedoor 140 may be locked in the closed position by operating thehandle 410 to move thelatching mechanism 400 in the latching position. The tapered points 580, 590 of the upper and lower latching pins 480, 530, respectively, provide an inclined-plane mechanical advantage in closing thedoor 140 and maintaining thedoor 140 in the closed position. The tapered points 580, 590 guide the latching pins 480, 530 into a central opening of the pin receiver provided on the door, thereby drawing thedoor 140 closed and compressing the seal between thedoor 140 and the sealingface 130 on thedoor frame 120. The tapered points 580, 590 are desirably shaped as to guide the upper and lower latching pins 480, 530 into the opening of the pin receiver. Alternatively, or in addition, the pin receiver may have a tapered surface to guide the latching pins 480, 530. - With reference to
FIG. 14A , a cross sectional view of theseal 170 is illustrated in combination with aseal retainer 340. Theseal retainer 340 is secured to the outside perimeter of thedoor 140 or it may be integrally formed with thedoor 140. In one embodiment, the seal retainer is formed as a groove on thedoor 140 to provide a guide for the installation of theseal 170. Theseal retainer 340 is desirably provided on the side of thedoor 140 that engages the sealingface 130, such as illustrated inFIG. 4 . In order to provide a watertight connection between thedoor 140 and the sealingface 130 of thetub 10, theseal retainer 340 is provided along the entire interface between thedoor 140 and the sealingface 130. In one embodiment, the seal retainer may be provided on the sealingface 130 and thedoor 140 may be pressed against the sealingface 130 to compress theseal 170. Theseal 170 may be secured within theseal retainer 340, such as by an adhesive bond. - With continuing reference to
FIG. 14A , theseal retainer 340 receives afirst portion 350 of theseal 170. Theseal 170 further includes asecond portion 360 that is compressible between thedoor 140 and the sealingface 130 of thetub 10. Thesecond portion 360 of theseal 170 includes a plurality of hollow cavities that are compressible when thedoor 140 is in the closed position. In the embodiment shown inFIG. 14A , a largercentral cavity 370 is flanked by two smallerlateral cavities 380 provided on the exterior of thecentral cavity 370. Thecentral cavity 370 and thelateral cavities 380 are compressible between a fully extended shape when thedoor 140 is in the opened position and theseal 170 is decompressed and a collapsed shape when thedoor 140 is in the closed position and theseal 170 is compressed. In one embodiment, theseal 170 is made from an elastic material, such as rubber or silicone. Other flexible and resilient materials may be used to create the watertight connection between thedoor 140 and sealingface 130. -
FIG. 14B illustrates another embodiment of theseal 170. Theseal 170 has a base 600 having one ormore barbs 610 configured for being received within aseal retainer 340. Theseal 170 further includes asecond portion 620 that is compressible between thedoor 140 and the sealingface 130 of thetub 10. Thesecond portion 620 of theseal 170 includes ahollow cavity 630 that is compressible between thedoor 140 and the sealingface 130 when thedoor 140 is in the closed position.
