DETAILED DESCRIPTION

(58) 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.

(59) 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.

(60) 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.

(61) Referring now to the drawings, and particularly to FIGS. 1, 2a, 2b, 3b, 5a, and 5b, a preferred embodiment of a telepole device 1 used for cleaning swimming pools is shown, including an outer/lower tube 2 having a collar element 3 with a detent locking device 4 mounted thereon, and an inner/upper tube 5 that slides through an opening in the collar element and within the outer tube. Preferably, the inner/upper tube has a profile with a smaller circumference than that of the opening of the collar element and the outer/lower tube so that it may readily slide within/through those elements in order to provide a telepole device having an adjustable length. Further, the inner/upper tube has a gripping portion 8 that may be attached with rivets, screws or other temporary or (semi-)permanent attachment devices. The gripping portion provides an area for a user to grip/grasp the telepole device and also prevents the inner tube from sliding entirely within the outer tube as the circumference of the gripping portion is larger than that of the collar element and/or outer/lower tube. Further, attachment devices (rivets, screws, or the like) can prevent the gripping portion from being “bumped” off the end of the tube when the inner tube slides into the outer tube, and they also make removing and/or replacing a worn handle possible.

(62) 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.

(63) 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.

(64) 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.

(65) 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.

(66) 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.

(67) FIG. 3a shows an example of a preferred inner tube which is configured to provide a watertight seal. The inner tube has a barrier 17 which prevents water from entering the inner tube through the series of detent holes 6 along the length of the inner tube. Preferably, the barrier runs the length 17a of the inner tube, and is configured to allow the detent pin 7 enough space to sit within the hole 10a of the housing 10 and a detent hole 6 in the inner tube when the spring 9 is in its normal, relaxed position. In such embodiments, almost the entire interior volume of the inner tube is watertight; the only portion “open” to water is the small sliver of space between the tube outer wall and the barrier 17, into which the pin protrudes when engaged. Although a watertight telepole device is desirable for many reasons in pool/water cleaning applications, persons of ordinary skill in the art will appreciate that the numerous benefits provided by this invention may still be realized even in non-watertight embodiments.

(68) 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.

(69) 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.

(70) 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.

(71) 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.

(72) 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, FIGS. 15a and 15b show two possible configurations of inner/reinforcement walls provided within a tubular handle. In FIG. 15a, a single reinforcement wall extends along a hollow portion of the inner tube from one side of the tube to another. In FIG. 15b, additional walls are provided which cross at least a portion of the tube's inner profile and intersect with each other at approximately the center of the inner portion of the tube. Persons of ordinary skill will understand that these are just examples of some of the possible configurations of reinforcement wall(s) within an inner tube, and that other possible configurations and numbers of walls which may be provided are virtually unlimited. As an example, FIG. 22 shows inner/reinforcement walls provided within a telepole having an elliptical profile. In such an embodiment, both the outer/lower tube and inner/upper tube of the telepole/tube have elliptical profiles, and inner/reinforcement walls are provided along the length of the inner tube.

(73) 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.

(74) 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. FIGS. 23a and 23b show possible buoyancy plug embodiments, wherein the plugs are configured to accommodate reinforcement wall(s) and/or thickened wall portion(s) within an inner/upper tube. In addition and as shown in FIGS. 24a-c, such plugs can be further adapted to function as interior locking devices having spreaders or an eccentric cam. In such embodiments, a cam assembly on the plug is configured as a “stop” to keep the inner/upper tube assembled within the outer/lower tube. As shown in the figures, a portion of the plug and/or cam assembly is wider than the opening on the compression nut to prevent the inner/upper tube from sliding out of the outer/lower tube when the telepole is fully extended. In a telepole device that does not have a compression locking device, a ridge on the collar of the device (similar to the compression nut shown in the drawings) may function to prevent the inner and outer tubes from separating.

(75) 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.

(76) 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.

(77) 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 FIGS. 7, 8, 9, 10, 11, and 11a, in one potential embodiment, the inner tube 5a may have a row of teeth 25a or other detent components along some or all of its length, a collar with a housing 10 formed into it, and a detent mechanism 4 including a device such as a rocking lever 26 with corresponding teeth 25b or some other element corresponding to the inner tube's detent component. Yet another preferred way of practicing the detent mechanism of the present invention is a spring-loaded lever detent means. As shown in FIG. 2c, unlike the rocking lever detent means of FIG. 8, the spring-loaded lever mechanism has a detent pin that fits into holes along the inner tube.

(78) 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.

(79) 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 FIG. 25, adding a second set of attachment holes (90 degrees away from the first set), the lever or button of the detent means can be oriented to the tool according to the preference of the user. The addition of such holes may also reduce wear and tear on the end of a telepole. Since cleaning tools are almost constantly exposed to pressure during use, a plurality of attachment holes may distribute that pressure to more than one area around the telepole's end. Thus, a second set of such attachment holes may be added to telepoles that have no lever/button detent means or “face” and are round with no identifiable sides/front/back.

(80) 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 FIG. 11a or threaded compression ring 29 shown in FIG. 12 may further be used with a collar element 3 or some other compression device element. For example, a compression gasket 30 having an opening that corresponds to the profile of an inner tube 5c may be provided. In this embodiment, the gasket opening and corresponding profile of the inner tube are configured with one or more corresponding “sides” 18a that prevent the inner tube from rotating within the collar.

(81) Additionally, FIGS. 12b, 12c, and 12d show a telepole device in accordance with the present invention having an outer tube including a collar element 3 comprised of a threaded portion 36 and a portion for receiving a compression gasket 34. Teeth, ridges, or other similar detent means 35 are formed into the compression gasket which matingly engage with inclusions, ribs or other similar detent elements 5b along the outer walls of the inner tube. Tightening the compression ring causes the teeth of the compression gasket to engage with the inner tube's detent elements and in turn prevents the inner tube from sliding within the outer tube. Conversely, loosening the compression ring disengages the teeth and detent elements, and permits a user to adjust the telepole's length by sliding the inner tube within the outer tube. In a another embodiment, the compression gasket may be provided with ribs or similar detent means which correspond to detent features along the outer walls of the inner tube, and which hold the inner tube in place along the length of the outer tube but allow the inner tube to rotate within the outer tube. In yet another embodiment, the inner/upper tube and the compression gasket and/or collar's opening may each have one or more corresponding sides that prevent rotation of the inner tube within the outer tube.

(82) 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.

(83) 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 FIG. 14, an outer tube may be provided with an inward/interior-facing protrusion 34 within its profile, and an inner tube may correspondingly have an indentation 35 within its profile. The indentation in the inner tube may be capable of receiving the outer tube's protrusion for the purpose of preventing the inner tube from rotating within the outer tube. Since such a configuration may make it difficult or impossible for the outer tube to receive standard cleaning tool attachment means, an adapter may be mounted on the outer tube's end to enable standard tools with V-clips to be attached to the present telepole device.

(84) 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.

(85) 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.

(86) 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.

(87) 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 FIGS. 16a/b and 17, a tubular handle of the type described herein having inner/reinforcement walls along its length may be attached to any type of tool, depending on the need of the user. If/when it is desired to remove/detach that tool from the tubular handle, the tool may be detached from the handle, as shown in FIG. 17.

(88) 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 FIGS. 18a-e, a quick-release device may be provided on the tool, handle, or both to enable ready attachment and detachment of the parts from each other. As shown in the drawings, a preferred quick-release device for use with the present invention is a spring-loaded button mechanism, however, persons of ordinary skill will appreciate that this is only an example of the many possible devices which may be used. For example, a quick-release device in accordance with the present invention may include a threaded end that can be twisted to either tighten or loosen the (tool) attachment, may be an interlocking device, and/or utilize V-clips, etc. The convenience provided by quick-releasing tools/handles is especially beneficial in applications of working with and finishing concrete wherein tools such as a bull float, trowel, rolling tamper, seamer, and various other tools or adapters are commonly used in conjunction with an extendable handle.

(89) 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 FIGS. 18c-e, a quick-releasing device/mechanism may be used to join one or more similar sections of tubular handle together. Persons of ordinary skill will appreciate that the quick-release mechanism may be provided on the tubular section(s) itself (FIG. 18c), on a coupling device (FIGS. 19a-c) for joining tubular sections, or both. Further, male and female mating ends may be provided in any configuration on the tubular sections and/or coupling devices in order to join similar sections of tubular handles together. Some examples include: a tubular handle in which one side is a male end configured to fit into the female end of another tubular handle; a tubular handle length that has only female ends; a tubular handle length that has only male ends; a tubular handle with at least one male end formed by ‘necking down’ the handle's male end or ends; and a tubular handle with at least one female end formed by ‘expanding’ the handle's female end or ends.

(90) Thus, the invention provides an improved telescoping pole with a variety of beneficial uses and applications. In certain embodiments, and as illustrated in FIG. 26, the invention preferably provides a pole with one or more features such as the following: 1. An elongated inside tube element has its outer surfaces ergonomically designed to be comfortable to a user's hands. 2. Holes and/or other ‘receiving’ or engaging means are provided in the walls of the inside tube and along the inner tube's length to allow engagement/disengagement between concentric lengthwise elements of the assembly, via detent means or otherwise, to facilitate temporarily selecting a desired length for the assembly. 3. The telepole can be adjusted with the use of a detent means or similar device that enables a ‘positive’ lock/unlock to occur at a selected length/position of the respective generally concentric tubes. 4. One or more rivets or other fastening devices can be used to mount detent housing(s) on an end of outside tube. Alternatives include, without limitation, gluing, welding, etc. 5. A stop mounted on the inside tube prevents the inside tube from passing all the way out of or separating from the outside tube. 6. The stop has a gap or other portion that allows it to pass by rivets, fasteners, or other obstructions without getting hung up on those elements. 7. An extra set of attachment holes is provided, preferably offset (at a different distance from the end of tube) from first set of holes, and/or at a different radial position/orientation. 8. A grip mounted with one or more screws or fasteners; preferably mating screws that thread into each other. 9. Mating screws to help eliminate the risk of screw holes in the tube becoming stripped. 10. A mounted grip that serves as a true ‘stop’ to prevent the inside tube from sliding all the way “into” the outside tube. 11. Telepoles above having grip on the end, grip further having an opening broad enough to make visible/display reinforcement walls (for marketing or other purposes). 12. Telepoles with grip above, with grip having a clear end that allows customers to see the inside reinforcement walls in the handle (this will allow a user to be forceful with the tool at the grip without irritating or possibly harming his/her hands on an open ended grip). 13. One or more thickened portions or interior walls of inside tube to prevent water from entering one or more hollow areas of the tube(s). 14. The inside tube is keyed to the collar and/or other corresponding element(s) of the outside tube. 15. A lever and/or detent housing is ergonomically designed to be comfortable to users' hands. 16. A plug in the end of the inside tube helps keep the tube and/or the entire assembly relatively watertight and buoyant.

(91) In FIGS. 27 and 28, offset attachment holes are illustrated in further detail. Persons of ordinary skill in the art will understand that, among other things, these holes are used to engage a brush or other tool to the end of the pole. Detaching the tool from the pole in prior art systems can involve pressing spring-loaded detents out of engagement with these holes and then quickly rotating or twisting the inner/outer tubes with respect to each other to complete the disengagement. By offsetting the attachment holes as in FIGS. 27 and 28, it is less likely that the tool will accidentally be “reattached” in other holes during such twisting/removal.

(92) A further listing of some of the features of the invention includes the following: An adjustable telescopic pole for cleaning swimming pools comprised of at least two tubes (one inside the other) that can be set for use at different lengths and has a detent mechanism that locks the tubes into their relative lengthwise positions. Detent mechanism is activated/deactivated by a depressible button. Detent mechanism is activated/deactivated by a lever. Detent mechanism includes one or more spring type of components Locking device includes more than one detent or locking mechanism to lock inside tube in position. Outside tube has a collar of some sort, to which the inside tube is keyed to prevent the inside tube from rotating relative to the outside tube. Inside tube has holes or other mating elements to receive the locking portion of the detent mechanism (i.e. detent pin/teeth). Inside tube has one or more thickened portions along its length to provide strength. Thickened portion along length of inside tube further has holes, grooves or other features along it to receive the pin/teeth of a detent mechanism, thickened portion being thick enough that the holes, grooves or other receiving features do not penetrate into a center hollow portion of the inside tube (and thus prevent water from entering the inside area of the inner tube). Inside tube has a hollow portion along its length, a specific cross-sectional profile, and one or more interior walls that extend across at least a portion of the hollow inside area of the profile. Said one or more interior walls extending across at least a portion of the hollow area to prevent inside tube from filling with water Inside tube having one or more interior walls, said one or more interior walls formed separately and inserted into the hollow portion of the tube Inside tube having a plug or some other device that serves as a stopper to prevent water from entering the hollow portion of the tube from the tube's end when submerged in a swimming pool or other body of water. Inside tube having a cap-like grip on the end opposite the plug Grip further being mounted with screws, rivets, etc. to the end of the inside tube to prevent it from being inadvertently bumped off when the inside tube is collapsed lengthwise into the outside tube. Screws, rivets, etc. holding grip onto the end of the inside tube are removable and replaceable to enable a user to install a new grip. Screws or other removable mounting means that mate to each other (to reduce/prevent the possibility of screw holes in the tube from becoming enlarged or stripped). Detent button/lever is mounted in a housing located in collar means. Housing has one or more sides that protect at least a portion of the button/lever from being bumped by a user's hands (or some other object) and being accidentally activated/deactivated during use. Housing/lever/button mechanism are ergonomically shaped to prevent hands from becoming sore or injured. Inside tube is ergonomically designed to prevent hands from becoming sore or injured (this is in contrast to poles having, for example, an inside tube with a sharply-cornered hexagonal cross-section that are, consequently, painful to grasp). Inside tube is fitted with a saddle bushing or other type of guide to keep inside tube aligned with inside walls of outer tube. Saddle bushing or other type of guide serves as a ‘stop’ to prevent inside tube from separating from outside tube when the telepole is extended. Housing is permanently mounted to outside tube with rivets or some other attachment method. Housing is mounted to outside tube in a manner that makes the housing removable/replaceable. End of outer tube has additional set of holes about its diameter to receive attachable/detachable tools. Additional set of tool attachment holes is placed at a different distance from tube's end than first set of tool attachment holes. Telepole with compression locking device, said compression device (as in FIGS. 10, 11, 12a-d) having the ability to ‘mate’ with ribs, ridges, etc. formed on inside tube.

Standard telescopic pole with inside tube having one or more inner wall(s) across a portion of its profile (and run substantially the length of the inside tube). Pole above having one or more inner wall(s) that extend across a portion of the inside tube's profile, but the wall(s) do not necessarily connect to another side of the profile (i.e., wall(s) extend only ¼ way across the diameter of the tube's profile). Plug for compression locking pole having inside tube with one or more inner walls. Plug for compression locking pole having inside tube with one or more thickened portions. Compression pole having extra set of attachment holes at its end. Extra set of attachment holes on compression pole being offset (at different distances from end of tube than first set of attachment holes). Compression pole with grip serving as a stop by being mounted on end with screws, mating screws, etc. Compression pole with inside tube keyed to collar of outside tube Above embodiment(s), further having one or more inner reinforcement walls extending across at least a portion of the inside tube's diameter. Above embodiment(s), further having a stop to keep the inside tube from being pulled out of the outside tube. Above embodiment(s), further having a grip mounted with screws, mating screws, etc. A telescopic pole comprised of three lengths of tubing, each fitting within the other, having all the same advantages of the invention(s) as described above.

Making tools with reinforced handles, reinforcement walls/components being done in a secondary operation from the initial formation of the tube (i.e. a sliding a sleeve into the inside tube and calling it ‘reinforced’).

(93) 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.
