DETAILED DESCRIPTION
[0082] Embodiments of the present invention will now be described with references to the accompanying figures, wherein like reference numerals refer to like elements throughout. The terminology used in the description presented herein is not intended to be interpreted in any limited or restrictive manner, simply because it is being utilized in conjunction with a detailed description of certain embodiments of the invention. Furthermore, various embodiments of the invention (whether or not specifically described herein) may include novel features, no single one of which is solely responsible for its desirable attributes or which is essential to practicing the invention herein described.
[0083] Although the examples of the many various methods of the invention are described herein with steps occurring in a certain order, the specific order of the steps, or any continuation or interruption between steps, is not necessarily intended to be required for any given method of practicing the invention.
[0084] Persons of ordinary skill in the art will understand that the apparatus of the invention and various of its many methods can be practiced using any of a wide variety of suitable processes and materials. By way of example and not by way of limitation, certain embodiments of the apparatus can be manufactured via processes using one or more steps of routing, drilling, turning, injection molding, extruding, thermo-forming, casting, and many other existing and new processes that may come into being. Materials are not limited in any way and could extend from metals to plastics, to resins of all types. A preferred material is lightweight, non-corrosive and will hold up to the exposure anticipated in its eventual usage (including by way of example, chlorine water, salt water, marine environments, UV exposure, etc.). A preferred method of manufacture is by injection molding and extruding various components of the embodiments, and by machining others and/or buying them from commercially-available sources.
[0085] Referring now to the drawings, and particularly to
[0086] Preferably, the outer/lower tube has a series of openings/holes 2a for receiving attachment means of cleaning tools, and has at least one drain hole 2b for allowing water trapped in the outer/lower tube to drain out. As will be further described herein, some of the many alternative embodiments of the invention can be practiced without all of these elements. Moreover, persons of ordinary skill in the art will understand that the elements described herein may even be provided in other embodiments in a wide variety of other forms depending on the desired use/application of the device.
[0087] As indicated, the present invention preferably includes means to adjust the length of the pole within the assembly. Persons of ordinary skill in the art will understand that this can be accomplished in a wide variety of ways, using various apparatus and methods. In a preferred embodiment of the present invention, the inner/upper tube has a series of openings/holes 6 along its length that are configured to receive a detent pin element 7 located in a housing 10 of the collar element in order to “lock”/temporarily secure the inner/upper tube in a desired position within the outer/lower tube. The detent pin element is affixed to a spring element 9 that, when in its normal “relaxed” position, allows the pin element to sit/rest simultaneously in a hole 10a through the housing of the collar element and one of the holes of the series 6 in the inner tube, thus locking the inner/upper tube into a desired position within the outer/lower tube. In addition, a button element 11 is mounted within the housing above the detent pin and is held in place by tab elements 12. When the button element is depressed by a user, the spring is pressed against an uneven surface 13 in the housing and forced into an “unrelaxed” position which in turn causes the pin element to be lifted out of the inner tube's hole 6, thus releasing the inner tube so that it can be moved into a new position within the outer tube. Releasing the button allows the spring to revert to its normal, relaxed position and enables the detent pin to reenter a hole 6 in the inner tube so that the inner tube may be secured in another desired position within the outer tube.
[0088] Further in a preferred embodiment, a saddle bushing 5a is provided between the outer wall 15 of the of the inner tube and the inner wall 16 of the outer tube. The saddle bushing element has a post element 14 that fits into a designated hole 6a for receiving the post element in the inner tube in order to guide the inner tube into proper alignment with the outer tube (i.e., so that the detent pins may be readily aligned with the detent holes) and to prevent the inner tube from sliding past the housing and separating from the outer tube. Further, a plug 21 at the end of the inner tube opposite the end with the gripping element 8 preferably prevents water from entering through the inner tube's end.
[0089] Telepoles which are used in swimming pool (or similar) cleaning applications are repeatedly submerged in water of varying depths. Accordingly, a telepole capable of reaching below the water's surface (at times a significant amount below) is desirable, especially when cleaning deep areas of a pool, during long reaches, or both. It is a well known issue that water may easily enter the outer tubes of prior art extendible poles, through an attachment hole or other opening, and it may likewise enter the inner tube of the pole assembly. It is very undesirable, however, for water to enter the inner tube because, for example, it adds a significant amount of weight to the telepole device making it more difficult to maneuver the pole/assembly and taking longer to drain the device.
[0090] Accordingly, in a preferred embodiment of the present invention, the inner tube is configured such that water is prevented/stopped from entering some (and preferably most or even all) of the hollow portion of the inner tube. Persons of ordinary skill in the art will appreciate that there are numerous potential inner tube configurations which may provide a water tight seal to the telepole device, and that depending on the intended use of the device, any of these potential configurations (or combinations of them) may be desirable for use with the present invention. Moreover, any existing non-water tight inner tube of an existing device may be retrofitted with an inner tube that is configured to prevent water from leaking in.
[0091]
[0092] Further in a preferred embodiment, the inner tube has a distinct profile/shape that corresponds or is keyed to the profile/shape of the opening 10b of the collar element through which it extends. Among other things, this keyed relationship can prevent the undesirable rotation of the inner/upper tube within the collar element and outer/lower tube, and thereby allow the user to have more certain control over the assembly during its use in cleaning or other activity. In this preferred embodiment, the collar's opening and the profile of the inner tube are similarly out-of-round having one or more corresponding “sides” 18a that prevent the inner tube from rotating within the collar. This ensures that the pin 7 will always be aligned with the series of detent holes 6 along the length of the inner tube, and it enables a user to maneuver attached tools more effectively during cleaning.
[0093] In a preferred embodiment of the present invention, an inner/upper tube with a profile that includes one or more additional inner walls across its diameter is provided in order to give the inner/upper tube added strength along its length. This improved inner/upper tube with additional inner strengthening walls may be used with existing telepoles (for swimming pools or other uses) in a retrofit embodiment. In this embodiment, the existing inner/upper tube may be replaced/retrofitted with an improved inner/upper tube with additional inner strengthening walls or means. In this embodiment, the existing and improved inner/upper tubes have the same outer profiles along their lengths such that they both readily slide through the collar and outer/lower tube, and can easily be replaced with one another.
[0094] More broadly, persons of ordinary skill in the art will understand that the various components of certain embodiments of the invention can be provided in a modular and interchangeable form, facilitating economic manufacture/assembly/distribution of the devices, easy replacement of worn or damaged parts, exchange of longer pole/tube elements for shorter ones (and vice versa), and other benefits.
[0095] Persons of ordinary skill in the art will appreciate that a variety of inner tube profiles/shapes may be provided in accordance with the present invention. For example, among the many benefits provided by varying profiles/shapes/configurations, the inner tube(s) of the present invention may be configured to reduce bending of the inner tube, prevent water from entering the inner tube through the detent holes, keep the inner tube from rotating within the outer tube, and/or facilitate a plug with a locking device having a shape that corresponds to a tube's profile.
[0096] In a preferred embodiment of the present invention, additional wall(s) 17b may be provided along the length 17c of the inner tube to increase its strength/resistance to bending, denting, etc. Persons of ordinary skill in the art will appreciate that those additional wall(s) may be configured in many possible ways while still providing additional strength along the length of the tube. For example,
[0097] In addition to or within another embodiment, a thickened wall portion 19 along the length of an inner tube may be provided with detent holes 6 drilled partially into that thickened portion to accommodate detent pins, and the remaining portion 20 providing a barrier that prevents water from entering the inner tube.
[0098] In embodiments having thickened wall portions and/or reinforcement walls, buoyancy plug(s) may be provided within an inner/upper tube to maintain and/or increase the buoyancy of the tube.
[0099] In another alternative embodiment of the present invention, the inner tube may be provided with notches 22 about its circumference or other/similar sides that correspond to protrusions/tabs in the collar element in order to prevent the inner tube from excessively or undesirably rotating within the outer tube during use. Alternatively or concurrently, further barriers/parts such as a sleeve element 23 or cup element 24 may be permanently or temporarily provided in key areas to provide a water tight seal to the inner tube.
[0100] Furthermore in an alternative embodiment of the present invention, an outer tube having a profile that is not perfectly round may be provided along with an inner tube having a locking device mounted thereon or integral therewith. In this embodiment, the locking device is activated when a user twists the inner tube and causes the locking device to wedge itself against the uneven inner walls of the outer tube. The locking device is deactivated by a twist in the reverse direction.
[0101] Persons of ordinary skill in the art will appreciate that the detent mechanism of the present invention has many potential embodiments, all of which provide the benefits realized by the present invention. Referring now to
[0102] Persons of ordinary skill in the art will also appreciate that the detent components of the inner tube may be configured, formed and/or attached to the inner tube in many ways. For example, a detent component 25a may be provided on an external portion of an inner tube 5a having a round profile. The external component may be integrally formed with the inner tube or permanently or temporarily attached to the inner tube during assembly. This external component may provide “sides” on the inner tube that correspond to indentations/protrusions/tabs on the collar in order to prevent unwanted/excessive rotation of the inner tube within the outer tube.
[0103] With the addition of a lever/button detent means, a “face” is created on the outside of the telepole (rather than the telepole simply being round with no identifiable sides/front/back). Therefore, additional attachment holes are needed to accommodate tools such as brushes having V-Clips which are mounted to the telepole in a horizontal position (with respect to the direction the tool moves when it is used to clean a pool, for example). Other tools such as leaf nets have V-Clips mounted in a vertical position in relation to the way the net moves through the water. As shown in
[0104] In an alternative embodiment, the inner tube may be formed with inclusions 5b, ribs or other detent components which correspond to complementary detent elements provided in a detent mechanism located adjacent to or within the outer pole's collar element, such as a rocking lever 26 or an end-hinged lever 27. In addition, a compression device such as the end-hinged lever shown in
[0105] Additionally,
[0106] Further, a plug or internal locking device 37 may be fitted into the end of the inner tube to further prevent the inner tube from slipping or rotating within the outer tube, and may even keep water from entering the inner tube. In certain embodiments, the internal locking device may include an off-center cam 38 or other spreading device 31 having moving parts 32 that can be wedged against the inner walls of the outer tube in order to lock the inner tube in a desired position along the length of the outer tube. Even further, the inner tube may have one or more sides that are keyed to correspond with one or more sides of the compression device and/or its components to facilitate “locking” the inner tube in place with respect to the outer tube and preventing any undesired or excessive rotation of the inner tube within the outer tube.
[0107] Moreover, a telepole with any suitable compression device for “locking” the inner tube in a given position within the outer tube may further include an outer tube which is configured to prevent the inner tube from rotating within the outer tube. In one potential embodiment, as shown in
[0108] In some of the many alternative embodiments of the present invention, any levers and/or buttons, etc. may be partially or entirely recessed into a housing 10 that has sides 28 to protect the levers and/or buttons from being bumped by a user's hands or any other object or surface that may cause damage to or accidental release of the lever or detent mechanism.
[0109] In further alternative embodiments, a telepole for cleaning swimming pools in accordance with the present invention may include an outer tube whose profile is not uniformly round/circular along its length, and an inner tube having a cam or other similar spreading device 31. This configuration increases the ability of the inner tube to be “locked” in place within the outer tube. By twisting and rotating the inner tube within the outer tube, a user can misalign the cam or activate the spreading device so that the sides of its moving parts 32 engage themselves with the out-of-round inner walls 33 of the outer tube and lock the inner tube in a desired position. A reverse action disengages the cam or spreading device and unlocks the inner tube and permits readjustment of the telepole's length.
[0110] Persons of ordinary skill in the art will appreciate that the “locking” mechanisms described herein may be combined with other locking mechanisms described herein or others which are known in the art in order to provide a device that achieves the objects presented herein. On the other hand, any locking mechanism may stand alone to effectively achieve those objectives.
[0111] The present invention further provides means for attaching, detaching and re-attaching a variety of tools to the tubular handle of the present invention. As shown in
[0112] In an embodiment of the present invention, that attachment means may be provided as a “quick-release” device for easy attachment and detachment of the tool and the tubular handle. As shown in
[0113] Further, the benefits provided by a quick-release mechanism can be realized in attaching one or more tubular sections together for increasing the overall length of the handle. As shown in
[0114] The apparatus and methods of my invention have been described with some particularity, but the specific designs, configurations, and steps disclosed are not to be taken as delimiting of the invention in that various modifications will at once make themselves apparent to those of ordinary skill in the art, all of which will not depart from the essence of the invention, and all such changes and modifications are intended to be encompassed within the appended claims.
