Swimming pool vacuum hose attachment with relief port for spot cleaning and system incorporating the same
A spot cleaning device for a swimming pool cleaning system having a vacuum source and a vacuum hose having an end portion forming a vacuum inlet. The device includes a releasable connector for releasably mounting it on the pole and has a hollow body to which the vacuum hose is coupled and an inlet port which communicates with the inlet port of the vacuum hose. A vacuum relief port is provided in the hollow body adjacent the inlet port. The device is arranged to be positioned adjacent material, e.g., leaves, mud, algae, stones, etc., to be removed from the pool so that when the vacuum source is operated suction at the inlet port pulls that material directly into the inlet port without creating a cloud of debris, and with the vacuum relief port preventing the device from becoming hung up or stuck to a surface of the pool.
This application is a Continuation-In-Part of U.S. patent application Ser. No. 10/972,948, filed on Oct. 25, 2004, entitled Swimming Pool Vacuum Hose Attachment for Spot Cleaning, whose disclosure is incorporated by reference herein.

BACKGROUND OF THE INVENTIONThis 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, ease 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 INVENTIONIn accordance with one aspect of this invention a spot cleaning vacuum head is provided for a swimming pool cleaning system including 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 tubular section, an outlet port and an inlet port. The tubular section includes a sidewall having a longitudinal axis. The tubular section terminates in an opening having a periphery defining the inlet port. The inlet port forms the free end of the body and is in fluid communication with the outlet port. The outlet port is arranged to be releasably coupled to the free end of the vacuum hose. The releasable connector comprises a projecting member extending away from the tubular section. The projecting member is arranged to be releasably secured to an end portion of an elongated pole to mount the spot cleaning vacuum head on the pole, whereupon the spot cleaning vacuum head can be moved by manipulation of the pole into position within a swimming pool so that the free end of the body is below the surface of water within the pool and immediately adjacent material desired to be removed. 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. The tubular section includes a vacuum relief port, e.g., a V-shaped notch, a window, at least one aperture etc., located adjacent the inlet port. The vacuum relief port serves to prevent the spot cleaning vacuum head from becoming stuck on a surface, e.g., the bottom or a side wall, of the pool during the operation of the swimming pool cleaning system in the event that the periphery of the inlet port engages a surface of the pool to form a seal therebetween.
DESCRIPTION OF THE DRAWING
Referring now to the various figures of the drawing wherein like reference characters refer to like parts, there is shown at 20 in
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
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
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 1½ inch (38.6 mm) or 1¼ inch (31.5 mm). This enables it be readily releasably received in the collar 22A of the vacuum hose 22 as shown in
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
Turning now to

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 releasable 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 releasable 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.

The spot cleaning vacuum head 120 basically comprises a hollow body 126 formed of any suitable material, e.g., PVC piping, and has three slightly conically shaped sections. The lowermost section is designated by reference number 132 and has a lower circular peripheral free edge 128 forming the inlet opening to the vacuum head. The uppermost section is designated by the reference number 134 and terminates at its upper end in a circular opening defining the outlet port 138. The intermediate section of the tubular member 126 joins the sections 132 and 134. All of the tubular sections are axially aligned along a common longitudinal central axis. The inlet port enables 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 outlet port 138 is in fluid communication with the inlet port 128 through the hollow interior of the body 126 of the spot cleaning vacuum head 120. The outside diameter of the portion of the tubular section 134 forming the outlet port is either 1½ inch (38.6 mm) or 1¼ inch (31.5 mm). This enables it be readily releasably received in the collar 22A of the vacuum hose 22 to mount the spot cleaning vacuum head 20 on the vacuum hose 22. A circular ridge, not shown, may be provided to extend about the periphery of the section 134 adjacent the outlet port 138 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 peripheral portion of section 132 forming the inlet port is may be formed of a resilient or soft material, e.g., be rubberized, to form 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 138 may include an annular bead extending thereabout similar to that of the embodiment of
The vacuum head 120 is arranged to be mounted on the pole 124 by means of a releasable connector 130. That connector is in the form of a projecting member extending radially outward from the body 126 and terminates in a portion 148 that extends generally parallel to the central longitudinal axis of the tubular body 126. The portion 148 of the connector 130 is of an elongated, semi-circular trough shape. The outside diameter of the portion 148 is just slightly smaller than the inside diameter of the hollow distal end of the pole 124. The portion 148 of the connector 30 includes one conventional butterfly-like, spring-biased locking member 150. The locking member 150 basically comprises a pair of projecting fingers 150A and 150B fixedly mounted on respective ones of a pair of legs of a V-shaped spring 150C. Preferably the fingers 150A and 150B and the V-shaped spring are formed as an integral unit of any suitable material, e.g., plastic or metal. The fingers 150A and 150B are biased by the spring 150C to extend outward through the sidewall of the portion 148 of the connector 130 for releasably location within the apertures 124A and 124B, respectively, in the pole 124 when spot vacuum head 120 is mounted on the pole 124.
The securement of the spot cleaning vacuum head 120 onto the pole 124 is achieved by inserting the portion 148 of the connector 130 into the hollow distal end of the pole 124, whereupon the domed ends of the fingers 150A and 150B of the locking member ride 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. When the fingers 150A and 150B reach the diametrically aligned apertures 124A and 124B the fingers snap-fit into the respective apertures, thereby releasably securing the spot cleaning vacuum head 120 on the pole 124.
Once the vacuum head is so mounted and connected to the vacuum hose 122, 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 124 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 138 is located immediately adjacent the debris or other material to be removed. When the vacuum source is turned on the vacuum produced thereby is coupled through the hose and the hollow interior of the vacuum head, so that a confined and axially directed vacuum is created at the inlet port 138. This action pulls the debris directly into the inlet port, from whence it is are carried through the interior of the vacuum head and the vacuum hose 22 for collection.
In order to ensure that the vacuum head does not become stuck or otherwise immobilized during its use, such as could occur if the periphery of the inlet port 38 (of the embodiment of

As 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 and without the danger of the vacuum head being stuck on or to the surface of the bottom or side wall of the pool. 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.
