Cl. 4-256 6 Claims ABSTRACT OF THE DISCLOSURE A device for unclogging drains or the like which includes an elongated, hollow handle portion and an inflatable member connected to a terminal of the handle portion. The inflatable member includes a flexible strip which constitutes a former which may be longitudinally bent to selectively adjust the inflatable member to a rectilinear or curvilinear shape. A water conduit in communication with the hollow handle portion extends longitudinally through the inflatable member, and terminates in a nozzle having an outlet orifice. A source of pneumatic pressure inflates the inflatable member to seal the drain opening. A water source directs water through the handle portion, inflatable member and'nozzle to exert hydraulic pressure on obstructions in the drain line.
OBJECTS OF THE INVENTION It is an object of this invention to provide a device for unclogging drains or the like of simple, economical construction which may be readily and eflectively used by an unskilled person for clearing obstructions in plumbing facilities such as toilets, wash basins, sinks, etc.
Another object is to provide a device for unclogging drains or the like comprising an elongated, tubular, rigid portion which serves as a handle and also as a conduit through which water flows, and a flexible inflatable member through which water flows to a nozzle having an outlet orifice, the inflatable member being enlarged under pneumatic pressure to seal the drain opening.
A further object is to provide a device of the character described wherein the inflatable member includes an elongated, flexible strip over which an inflatable bladder is sleeved, the strip being longitudinally bent to selectively adjust the inflatable member toa rectilinear or curvilinear shape to facilitate use of the present devices for unclogging different types of plumbing facilities.
Other objects will be manifest from the following detailed description of the presently preferred form of the present invention taken in conjunction with the appended drawing.
DESCRIPTION OF FIGURES OF DRAWINGS FIG. 1 is a side elevational view of the present device for unclogging drains or the like illustrating its application;
FIG. 2 is an enlarged, fragmentary longitudinal sectional view of the flexible inflatable member forming a salient portion of the present invention;
FIG. 3 is a sectional view taken along the line 3-3 of FIG. 2 looking in the direction of the arrows, showing the inflatable member of the device in deflated position;
FIG. 4 is a sectional view similar to FIG. 3, showing the inflatable member in inflated position;
FIG. 5 is a fragmentary plan view of a flexible former comprising part of the inflatable member; and
FIG. 6 is a view similar to FIG. 2, showing an alternate position of the flexible inflatable member.
DESCRIPTION OF INVENTION Referring now in greater detail to the drawings, the device of the present invention includes an elongated han- 3,608,098 Patented Sept. 28, 1971 dle portion 10, to the lower terminal of which is aflixed an inflatable member 12.
Connection of handle portion 10 to flexible member 12 iseffected by means of a flexible former comprising an elongated metallic strip 20, shown to advantage in FIG. 5, one terminal of which is riveted, or secured in any other suitable manner to the lower terminal of tubular member 14, as indicated at 22. The opposite terminal of strip 20 is riveted or otherwise secured, as indicated at 24, to a nozzle 26 having an orifice 28 through which water is expelled. It will be noted from FIG. 2 that hose 16 extends through inflatable member 10 and is sleeved over strip 20, the terminal of the hose being frictionally held by a tubular extension 30 of nozzle 26. A short tubular member 32 is riveted to strip 20 at 34 in spaced relation to the lower terminal of pipe 14. V
A bladder 36 made of rubber or like expandable material is sleeved over a portion of hose 16 from nozzle 26 to a point spaced from the lower terminal of hollow tube 14. Bladder 36 includes an outer wall 38 and an inner wall 40, the latter being in contiguous engagement with the outer periphery of hose 16. An air chamber 41 is formed between inner wall 38 and outer wall 40'.
At a point spaced from the lower terminal of hollow tube 14, there is provided a circular block or collar 42 which is sleeved over hose 16 and tubular member 32, said block being provided with an annular flange 44 over which the terminal portion of bladder 36 is urged.
In cooperation with block 42, there is provided a cupshaped member 46 which is also sleeved on hose 16, a terminal portion of the cup clamping bladder 36 against block 42 to frictionally hold the same. Bolts 47 secure clamp member 46 to block 42.
It will be noted from a consideration of FIG. 5 that a convolute spring 48 is positioned over strip 20 between the lower terminal of handle 14 and tubular member 32. Spring 48 serves to prevent kinks in hose 16 at that point.
At a point immediately adjacent a terminal of tubular member 32, there are provided a plurality of openings 50 for flushing out the area between inner wall 40 of bladder 36 and hose 16 adjacent thereto.
As shown to advantage in FIGS. 1 and 5, an air inlet valve '52 extends through outer wall 38 of bladder 36 for delivering air into air chamber 41 between the inner and outer walls, for inflating the bladder under air pressure. The outer end of air inlet valve 52 is connected to an elbow 54. A short air feed pipe 56 extends from elbow 54, over which pipe is sleeved an air line 58 made of rubber or other flexible material.
A support bracket 70 maintains the air pump in adjacent fixed relation to handle portion 10 of the present device. Support bracket 70 includes a pair of like plates, each including a web portion 72, one lateral edge of which is arcuate as indicated at 74 to complement the contour of cylinder 62. The opposite lateral edge is also arcuate as indicated at 76 to complement the contour of handle portion 10. The two opposed plates are joined in clamping relationship with each other and fixed together by means of bolt and nut members 7 8.
Referring now to FIGS. 2 and 6, it will be noted that flexible portion 12 of the present invention is adapted to assume different shapes for use of the present device in clearing obstructions in various types of drain openings. It has been found that the curvilinear shape illustrated in FIG. 2 facilitates use of the present device in commodes or the like, while the rectilinear position shown in FIG. 6 is preferable for sinks.
Adaption of the present device for one use or the other is readily effected by bending former strip 20, which member fixes the contour of flexible member 12.
OPERATION In FIG. 1, there is illustrated the application of the device of the present invention in clearing an obstruction in a commode 80. For this purpose, a hose section 82 is connected at one end to coupling 18 of the present device, the opposite end of the hose being joined by a connector 84 to a faucet 86.
In order to adapt the device of the present invention for this use, flexible member 12 is bent into a curvilinear shape and inserted into the drain opening in the bottom of the commode bowl, with bladded 36 in deflated condition.
Piston 64 of the air pump is then actuated to force air through air feed line 58 into the chamber formed between outer wall 38 and inner wall 40 of bladder 36. Upon inflation of the bladder, the latter seals the drain opening and follows the contours thereof to effect an airtight and watertight seal.
Faucet 86 is then turned on to direct water through hose 82 down through handle 10, flexible member 12 through nozzle 26 and out orifice 28 to exert hydraulic pressure on the obstruction in the drain line, and force the obstruction downwardly out of the drain line into the sewer line.
The device of the present invention comprises a minimum of simple, readily assembled parts, thereby permitting economic manufacture thereof. The adjustability of the flexible member enables this device to be easily adapted for unclogging various types of plumbing facilities, use of the device being carried out with a minimum of instruction by an unskilled person.
