Washer/extractor with plastic hose connecting fitting
View Patent ↗A washer/extractor having a one-piece plastic water hose connecting fitting having a base plate, a tubular hose connection portion that defines a passageway communicating between a hose connected to the fitting and an opening in the wall to which the fitting is mounted, and a pair of clamping members disposed in parallel relation to a rear side of base plate. The wash tub opening has a key hole configuration which enables the arms of the fitting to be positioned into the opening in a first position of the base and upon rotation of the base plate to a second position locates the clamping arms behind mounting portions of the wall for securement by respective fasteners extending through the base plate, wall mounting portions, and clamping arms.
1. A washer/extractor comprising:
a wash tub,
a tumbler mounted for rotational movement within said wash tub,
a wall of the washer/extractor being formed with an opening,
a hose connecting fitting mountable on said wall about said opening,
said connecting fitting having a one-piece plastic construction including a base plate positionable adjacent an outer surface of said wall in surrounding relation to said opening,
said connecting fitting having a tubular hose connection portion integral with said base plate extending outwardly of said base plate and the wall upon which the fitting is positioned,
said tubular hose connection portion defining a passageway communicating between a hose connected to said hose connection portion and said opening,
said hose connecting fitting including at least two clamping members disposed in spaced relation to a side of said base plate opposite that from which said hose connection portion extends, said clamping members being spaced from the base plate a distance greater than a thickness of said washer/extractor wall,
said wash tub wall opening having a key hole configuration designed for receiving said hose connecting fitting clamping members upon positioning of said connecting fitting on said wall during mounting in a first position and which upon rotation of said hose connecting fitting to a second position relative to said opening locates said clamping members with a mounting portion of said wall disposed between each clamping member and base plate, and
a respective fastener positionable through said wall mounting portion and connectable between said base plate and each clamping member for securely retaining said connecting fitting in mounted position in said second position with said wall mounting portion in secure interposed clamped relation between said clamping members and the base plate.
2. The washer/extractor of claim 1 in which said clamping members are disposed on opposite sides of said base plate.
3. The washer/extractor of claim 2 in which said base plate has a substantially rectangular configuration, and said clamping members are disposed adjacent diametrically opposed corners of said base plate.
4. The washer/extractor of claim 3 in which said clamping members are disposed in parallel relation to each other.
5. The washer/extractor of claim 3 in which said clamping members each have a peripheral end disposed inwardly of a respective outer edge of said base plate.
6. The washer/extractor of claim 3 in which said wall opening has a substantially rectangular configuration sized smaller than said base plate wall with a pair of said mounting wall portions disposed at diametrically opposed corners thereof.
7. The washer/extractor of claim 6 in which said hose connecting fitting is positionable in a first position with said clamping members disposed adjacent diametrically disposed corners of opening opposite said mounting wall portions and is rotated 90° to said second position.
8. The washer/extractor of claim 1 in which said fastener is a tapping screw.
9. The washer/extractor of claim 1 in which said wall mounting portion and base plate have respective apertures that are in aligned relation to each other when said fitting is rotated to the second position.
10. The washer/extractor of claim 9 in which said clamping member has an enlarged thickness nib for receiving the end of said self tapping screw.
11. The washer/extractor of claim 1 in which said clamping members each include a clamping arm portion disposed in parallel spaced relation to said base plate and a connecting portion integrally connecting said clamping arm portion and said base plate.
12. The washer/extractor of claim 1 in which said hose connecting portion extends at an acute angle to said base plate.
13. The washer/extractor of claim 1 including a sealing member interposed between an outer side of said wash tub wall and said base plate in surrounding relation to said wall opening.
14. The washer/extractor of claim 13 in which said sealing member is an O-ring, and said base plate is formed with a recess for partially receiving and retaining said sealing member during rotation of said connecting fitting from said first position to said second position.
15. The washer/extractor of claim 1 in which said wall is a rear wall of said wash tub, and said tubular portion defines a liquid flow passageway communicating with said opening, and into an interior of said wash tub.
