Device for attaching a fluid carrying hose to a receptacle drain

A device for fixing a fluid carrying hose to the drain of a sink receptacle. Principally applied to attaching a household washing machine waste water escape hose directly to the drain of a typical sink, thus preventing a fluid surge from dislodging the hose from the sink and causing subsequent damage. The device comprises a cuplike frame having a central pipe portion; means for attaching a fluid carrying hose to the central pipe portion; and means for removably attaching the frame to the walls of a sink drain.

BACKGROUND OF THE INVENTION 
The present invention relates to a device for attaching a waste water 
escape hose from a household washing machine to the drain hole of a sink. 
Heretofore it has been a necessary practice to simply drape or hook a 
washer waste water escape hose over the lip of a sink basin, and allow 
waste water to fall into the basin and subsequently seep into the drain 
passageway. This practice has caused a serious problem since the surge of 
fluid has often caused the escape hose to become dislodged from its 
support at the lip of the sink basin and resulted in flood damage to the 
surrounding room. 
This previously unresolved problem is overcome by the present invention 
whereby the fluid carrying hose is securely clamped to the sink drain 
allowing fluid to flow directly to the drain hole, and preventing the hose 
from becoming dislodged with resulting damage. 
SUMMARY OF THE INVENTION 
Consequently, it is an object of the present invention to provide a device 
for attaching a fluid carrying hose directly to the drain of a typical 
sink receptacle. 
It is another object of the invention to provide a device for fixing a 
fluid carrying hose to a sink drain which is economical to manufacture and 
is simple in construction. 
It is a further object of the invention to provide a device for fixing a 
fluid carrying hose to a sink drain which is easy to attach to and remove 
from a sink drain as required. 
It is a still further object of the invention to provide a device for 
fixing a fluid carrying hose to a sink drain which is adjustable to 
different size hoses and sink drains. 
Another object of the invention is to provide a device for fixing a fluid 
carrying hose to a sink drain which also permits alternate access to the 
drain facility. 
It is still another object of the invention to provide a device for fixing 
a fluid carrying hose to a receptacle drain which is also applicable to 
various other industrial, commercial and household uses. 
To achieve the above objects the present invention comprises a cuplike 
frame having a hollow pipe portion in its floor; means for attaching a 
fluid carrying hose to the pipe portion; and means for fixing the frame to 
the sink drain. 
According to the presently preferred embodiment the cup-like frame is set 
within the sink drain and rigidly retained therein by means provided. The 
fluid carrying hose is fixedly attached to the pipe portion. Fluid flows 
from the hose through the provided pipe portion and passes to the sink 
drain. The force caused by the flowing fluid is resisted, thereby 
preventing unwanted spillage and damage.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
Referring now to the drawings, the device for fastening a fluid carrying 
hose to the drain hole of a sink receptacle is shown to comprise a cup 10 
having a cavity 11, a plurality of draining holes 18, and a hollow pipe 
portion 12 concentric to the cup through its floor 30; means 16 for 
fastening cup 10 to the subject sink drain 22; and means 26 for attaching 
a fluid carrying hose 20 to pipe portion 12. 
All parts are preferrably composed of a rigid, durable material such as 
aluminum, stainless steel or firm plastic, although any other suitable 
material having similar characteristics may be employed. 
The cup is preferably constructed with a mouth 32 whose diameter is greater 
than that of the sink drain, a floor 30 whose diameter is smaller than 
that of the sink drain and inwardly sloping sides 28. In use the device is 
inserted into the sink drain and does not fall down the drain pipe 22, but 
is held in place at a level determined by the diameter of the particular 
drain. The floor of the cup 30 has a plurality of drain holes 18 so that a 
sink user may also expel fluid down the drain while the device is set in 
place. 
Pipe portion 12 has a concentric passageway 14 and in use is set within the 
central cavity of the subject escape hose 20. Fluid is free to flow from 
the escape hose 20, through pipe portion 12 and released to sink drain 22. 
Hose 20 is fixedly held around pipe portion 12 by suitable retaining means 
26 which in the preferred embodiment is a commonly available band type 
clamp which is well known in the prior art and is not a point of novelty 
in this application. A suitable adhesive bond may also be employed. 
Cup 10 is removably affixed to drain 22 by suitable fastening means which 
in the preferred embodiment consists of a plurality of screws which pass 
through holes in the sides of the cup and form a frictional adhesion with 
the sides of the drain when sufficiently tightened. This adhesion is of 
such a strength as to prevent the hose and device combination from coming 
ajar while fluid is flowing. 
In the preferred embodiment the heads 34 of screws 16 are of such a nature 
as to allow manual tightening and loosening without necessitating the use 
of tools. 
In use the fluid carrying hose 20 is permanently attached around pipe 
portion 12. The combination hose and retaining device is then inserted 
through the sink drain as required. Fastening screws 16 are subsequently 
tightened to retain the combination fixedly in drain 22 for use as fluid 
passes from hose 20 through passageway 14 to drain 22. While the device is 
fixed in place, the service of the drain is also available by means of 
drain holes 18 in the cup floor. When use is complete, screws 16 are 
loosened and the hose and device combination removed and stored. 
It is understood that changes in the structure, materials and operating 
conditions of the device are possible by those skilled in the art without 
departing from the nature and principles of the invention. The presently 
disclosed embodiment is employed for the purpose of illustration only and 
does not intend to limit the scope of the invention. 
It is further understood that the present invention is not limited to use 
with waste water escape hoses from household washing machines but may also 
be utilized in other fluid flow applications such as those typical to 
household, industrial and commercial processes.
