Description

BACKGROUND OF THE INVENTION

This invention relates generally to cleaning devices, and more particularly to devices for spot cleaning swimming pools and other chambers containing water or other liquids.
In U.S. Pat. No. 4,275,474 (Woodard) there is disclosed a vacuum head for a swimming pool cleaning system. The head is of the bristle-type for use particularly on vinyl liners, and the like, and comprises a wide, substantially shallow structure including an elongated top, walls and an outlet oriented upwardly from the top and communicating with the generally hollow interior of the head. The upright outlet forms a first connection for attachment of a vacuum hose to the head. A second hose of a diameter smaller than that of the first hose may be detachably positioned over an adapter member which is removably fitted within the first hose connection. Suction control in the form of at least one water by-pass valve is provided in the head top, enabling water sucked into the head interior to be selectively released therefrom, thereby preventing an excessively high suction force in the head intake area and such a force resulting from too great a build-up of vacuum within the cleaning system. Fixedly secured to the head top inner surface are a pair of axially opposed stabilizing weights and a connection for attachment of a handle or pole is provided at the top outer surface.
Other patents relating to devices for cleaning swimming pools are: U.S. Pat. No. 4,275,474 (Randall), U.S. Pat. No. 4,376,320 (Linda) and U.S. Pat. No. 4,637,086 (Goode).
While the aforementioned prior art devices may be suitable for their intended purposes they nevertheless leave something to be desired from one or more of the standpoints of simplicity of construction, easy of use and effectiveness. For example, some of such prior art devices when used to vacuum up finely dispersable debris, e.g., a dead algae pile, frequently create a cloud of such debris since the vacuum action is itself dispersed. To overcome that drawback of the prior art, persons cleaning pools have sometimes resorted to using the pole of a conventional pool vacuum head system, without the vacuum head, by merely attaching the distal end of the pole to the open distal end of the conventional vacuum hose via tape, e.g., duct tape. While such an arrangement enables effective spot vacuuming, the use of tape is undesirable and does not provide an elegant solution, e.g., untaping and retaping is messy, and time consuming.

SUMMARY OF THE INVENTION

A spot cleaning vacuum head for a swimming pool cleaning system. The system includes a vacuum source and a vacuum hose. The vacuum hose is coupled to the vacuum source and has a free end. The spot cleaning vacuum head comprises a body having a free end. The body comprises a releasable connector, a first tubular section having an outlet port, and a second tubular section having an inlet port. The second tubular section includes a sidewall having a longitudinal axis and terminates in an opening. That opening defines the inlet port and forms the free end of the body. The outlet port is in fluid communication with the inlet port and is arranged to be releasably coupled to the free end of the vacuum hose. The releasable connector comprises a projecting member extending outward from the longitudinal axis of the body of the spot vacuum cleaning head. The projecting member is arranged to be releasably secured to an end portion of an elongated pole to releasably mount the spot cleaning vacuum head on the pole.
When the spot cleaning vacuum head is mounted on the pole it can be moved by manipulation of the pole into position within a swimming pool so that the free end of the body is submersed below the surface of the water in the pool and immediately adjacent material, e.g., debris, algae, stones, etc., desired to be removed from the pool. The spot cleaning vacuum head is arranged so that when the vacuum source is operated suction is created at the inlet port to pull the material directly into the inlet port, thereby resulting in the spot cleaning of the swimming pool.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring now to the various figures of the drawing wherein like reference characters refer to like parts, there is shown at 20 in FIG. 1 a spot cleaning vacuum head constructed in accordance with one exemplary preferred embodiment of this invention. The spot cleaning vacuum head 20 is arranged for use with a conventional swimming pool vacuuming system including a source of vacuum (not shown), a flexible, e.g., corrugated, plastic vacuum hose 22 and a conventional elongated pole 24. The vacuum hose 22 includes a proximal end, not shown, which is arranged to be releasably secured to the vacuum source and to some vessel or receptacle (not shown) for collecting debris that has been removed from the pool. The distal end of the hose 22 is in the form of a female connector or collar 22A. Such collars are conventional circular tubular members whose distal or free end is of either 1½ inch (38.6 mm) inside diameter or 1 ¼ inch (31.5 mm) inside diameter. The pole 24 is also a conventional device like that used to releasably mount a conventional swimming pool vacuum head thereon. The pole is an elongated linear member, formed of any suitable material, such as a plastic (PVC) or aluminum. The pole is preferably tubular, i.e., includes a circular sidewall, in the interest of being light in weight, yet rigid and strong.
The distal end of the pole includes at least one aperture extending through the sidewall of the pole for receipt of a spring biased extending member or finger (to be described later) of the spot cleaning vacuum head 20 to releasably mount the head on the pole (as shown in FIG. 1, and as will be described in detail later). In fact, in accordance with one exemplary embodiment of this invention, there are two pairs of spring biased members or fingers forming a portion of the spot cleaning vacuum head. Such an embodiment makes use of a pole having a distal end which includes two pair of diametrically aligned apertures spaced longitudinally apart and located in the distal end portion of the pole. In particular, one pair of apertures 24A and 24B (FIG. 5) is located close to the distal end of the pole 24 and a second pair of apertures 24C and 24D (FIG. 5) is spaced slightly proximally of the first pair of apertures 24A and 24B.
The spot cleaning vacuum head 20 basically comprises a hollow body 26 formed of any suitable material, e.g., PVC piping, and has a free end 28. As best seen in FIGS. 3 and 4, the body 26 includes a releasable connector 30, a first tubular section 32 and a second tubular section 34. As will be described later, the tubular sections are axially aligned along a longitudinal axis 36 (FIG. 4). The first tubular section 32 has an outlet port 38. The second tubular section has an inlet port 40 (FIG. 6). The second tubular section includes a sidewall having a longitudinal axis extending coincident with the longitudinal axis 36 and terminating in an opening at the free end 28 that forms the inlet port 40. The inlet port 40 is located at the free (distal) end of the body 36 to enable the vacuum head to create a concentrated and directed vacuum, e.g., a “spot” vacuum, to the debris to be removed from the pool.
The second tubular section 34 also includes a sidewall having a longitudinal axis extending coincident with the longitudinal axis 36 and terminating in an opening that forms the outlet port 38. The outlet port 38 is in fluid communication with the inlet port 40 through the hollow interior of the body 36 of the spot cleaning vacuum head 20. The outside diameter of the portion of the second tubular section forming the outlet port is either 1 ½ inch (38.6 mm) or 1 ¼ inch (31.5 mm). This enables it be readily releasably received in the collar 22A of the vacuum hose 22 as shown in FIGS. 1-3 to mount the spot cleaning vacuum head 20 on the vacuum hose 22. A circular ridge extends about the periphery of the second section 34 adjacent the outlet port 38 to form a good seal when the portion of the second tubular section forming the outlet port is connected to the vacuum hose 22.
The distal end of the first tubular section 32 forming the inlet port is preferably formed of a resilient or soft material, e.g., it is rubberized. This forms an atraumatic tip for the spot cleaning vacuum head to minimize the chance that the vacuum head will damage the pool liner if it is used to clean an above ground pool. To further ensure that the tip will not damage the pool liner, the free distal end of the second section contiguous with the inlet port 40 preferably includes an annular bead 44 extending thereabout as shown in FIG. 6. As should be appreciated by those skilled in the art the distal end of the tip can be beaded, like shown, and be rubberized or otherwise formed of a soft, atraumatic material, or may be formed of the same material as that forming the tubular section 32. In fact, the distal end of the second tubular section at the inlet may not be beaded and/or formed of an atraumatic material if desired.
Turning now to FIGS. 3 and 4, the details of the releasable connector 30 will now be described. That connector is in the form of a projecting member extending outward from the body 26. In particular, the projecting member includes a first portion 46 and a second portion 48. The first portion 46 extends outward in a radial direction from the sidewall making up the body 26 and is perpendicular to the longitudinal axis 36. The first portion 46 of the projecting member 30 is fixedly secured to the body 26. The second portion of the connector 30 is of an elongated, cylindrical shape and extends parallel to the longitudinal axis 36. In the interest of weight the first 46 and second 48 portions of the connector 30 are hollow, e.g., tubular members. The outside diameter of the second portion 48 of the connector 30 is just slightly smaller than the inside diameter of the hollow distal end of the pole 24.
As best seen in FIG. 5, the second portion 48 of the connector 30 includes two conventional butterfly-like, spring-biased locking members 50 and 52 located therein. The locking member 50 basically comprises a pair of projecting fingers 50A and 50B fixedly mounted on respective ones of a pair of legs of a V-shaped spring 50C. Preferably the fingers 50A and 50B and the V-shaped spring are formed as an integral unit of any suitable material, e.g., plastic or metal.
The fingers 50A and 50B are biased by the spring 50C to extend outward through the sidewall of the second portion 48 of the connector 30 for releasably location within the apertures 24A and 24B, respectively, in the pole 24 when spot vacuum head 20 is mounted on the pole 24. The locking member 52 is constructed similarly to locking member 50. Thus, it basically comprises a pair of projecting fingers 52C and 52D fixedly mounted on respective ones of a pair of legs of a V-shaped spring 52E. The fingers 52C and 52D are biased by the spring 52E to extend outward through the sidewall of the second portion 48 of the connector 30 for releasably location within the apertures 24C and 24D, respectively, when spot vacuum head 20 is mounted on the pole 24.
The securement of the spot cleaning vacuum head onto the pole is achieved by inserting the second portion 48 of the connector 30 into the hollow distal end of the pole 24, whereupon the domed ends of the fingers 52C and 52D of the locking member 52 rides over the free distal edge of the pole to cause the fingers to move inward and to remain in that inward position as the free end of the sidewall of the pole passes over them. Continued movement of the second portion 48 of the connector 30 into the pole 24 causes the fingers 50A and 50B of the locking member 50 to retract in the same way as they pass the free distal edge of the pole. When the fingers 52C and 52D of the locking member 52 to reach the diametrically aligned apertures 24C and 24D, as the fingers 50A and 50B to reach the diametrically aligned apertures 24A and 24B, the fingers snap-fit into their respective apertures, thereby releasably securing the spot cleaning vacuum head 20 on the pole 24.
Once the vacuum head is so mounted and connected to the vacuum hose 22, as discussed above, it is ready to spot clean any portion of the pool. To that end, the user grasps the proximal end of the pole 24 and submerses the distal end on which the spot cleaning vacuum head 20 is mounted into the water in the pool so that the inlet port 40 is located immediately adjacent the debris or other material to be removed. In FIG. 1 debris is shown in the form of leaves 10 located on the floor of a pool 12. With the inlet port 40 of the vacuum head being located immediately adjacent, when the vacuum source is turned on the vacuum produced thereby is coupled through the hose and the hollow interior of the vacuum head 20, so that a confined and axially directed vacuum is created at the outlet port 40. This action pulls the leaves 10 directly into the inlet port, from whence they are carried through the interior of the vacuum head and the vacuum hose 24 for collection. The directed vacuum at the inlet port also tends to minimize the tendency of the leaves from billowing to form a cloud of dispersed leaves. The formation of a cloud of dispersed leaves is obviously undesirable, since it will require further vacuuming to remove them. In FIG. 2, the spot cleaning vacuum head 20 is shown being used to remove a pile of dead algae 14 which has accumulated on the floor of the pool. As will be appreciated by those skilled in the art, the ability of the spot cleaning vacuum head of this invention to direct the vacuum to its distally located inlet 28, is particularly useful for spot cleaning of algae or other readily disposable materials, since it is quite easy to create a cloud of dead algae or other dispersable materials if a more diffused vacuum head, like those of the prior art is used.
Thus, it should be appreciated from the discussion above that the subject invention offers the pool owner or cleaner the ability to utilize a conventional hose to effect spot vacuuming of debris or other unwanted materials located below the surface of the water in the pool without creating a cloud of dispersed debris/material. Among the debris/materials, the subject invention can be used to pick up are leaves, rocks, mud, dead algae, etc.
While the invention has been described in detail and with reference to specific examples thereof, it will be apparent to one skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope thereof.
