DETAILED DESCRIPTION

[0023] Referring now to FIGS. 1 and 2, there is seen assembled and exploded views, respectively, of an exemplary tool 100 according to the present invention. Tool 100 may be employed by a user for servicing various structures, such as, for example, aquariums. Tool 100 includes an extension pole 110 structured to be adjusted to a plurality of lengths for adjusting a length of tool 100, a grip portion 105 coupled to a proximal end 125 of extension pole 110 and structured to be gripped by a user, for example, by a person intending to service an aquarium, an attachment member 115 coupled to a distal end 130 of extension pole 110, and an accessory 120 (such as a cleaning accessory 120) structured to be removably attached to the attachment member 115.

[0024] Grip 105 may be constructed from any material suitable for being gripped by a user, such as, for example, soft foam (e.g., Ethylene-Propylene-Diene-Monomer or Nitrile PVC), sponge, polymer, wood, plastic (such as injected-molded plastic), and the like. In one embodiment, grip 105 (and/or the remainder of tool 100) is constructed from material(s) suitable for use both in fresh and salt water environments such as, for example, when tool 100 is used to service an aquariums. In an alternative embodiment, grip 105 is formed integrally with extension pole 110, such as, for example, when grip 105 includes surface texturing etched into or applied to extension pole 110. Grip 105 and/or other portions of tool 100 (such as extension pole 110) may be provided with one or more holes that permit any water trapped within tool 100 to drain after use, so that tool 100 may be properly stored. Of course, a person of ordinary skill in the art would recognize other manners for forming grip 105, and that the present invention as a whole is not intended to be limited by or to any specific type of grip 105.

[0025] Extension pole 110 is configured to be adjusted to various different lengths, thereby providing the ability to change the overall length of tool 100 to accommodate various different applications (such as, for example, when tool 100 is to be used to service different sized aquariums). Extension pole 110 may be constructed from any material suitable for a desired application, such as, for example, graphite, aluminum carbon fiber, steel, plastic, wood, and the like. Extension pole 110 includes cylindrical segments 200a, 200b, 200c, . . . 200e having progressively decreasing diameters with respect to proximal end 125 of extension pole 110. In this manner, each of cylindrical segments 200a, 200b, 200c, 200d slidably accommodates the adjacent distal cylindrical segment 200, thereby providing a telescoping ability for adjusting tool 100 to a desired length (such as, for example, the short and fully extended lengths shown in FIGS. 3a and 3b). Locking mechanisms 205a, 205b, 205c, 205d having progressively decreasing inner diameters with respect to proximal end 125 of extension pole 110 are provided for selectively and rigidly maintaining cylindrical segments 200a, 200b, 200c, 200e in place after adjustment of tool 100 to the desired length.

[0026] Referring now to FIGS. 4a through 4c, there is seen various views of an exemplary locking mechanism 205, according to the present invention. Locking mechanism 205 includes a locking nut 405 having an inside surface 420 provided with inner screw threads 410, a cylindrical tab 415, a first longitudinal bore 425 sized to slidably accommodate an adjacent distal cylindrical segment 200 and a second longitudinal bore 430 sized to slidably accommodate an adjacent proximal cylindrical segment 200 (see FIGS. 1 and 2 showing locking nuts 405a, 405b, 405c, 405d, with nuts 405 positioned closer to distal end 130 of extension pole 110 having smaller diameter bores 425, 430 compared to nuts 405 positioned closer to proximal end 125 of extension pole 110). Inner screw threads 410 of locking nut 405 engage with respective outer screw threads 435 of proximal cylindrical segment 200, such that when locking nut 405 is rotated and tightened with respect to proximal cylindrical segment 200, inside surface 440 of proximal cylindrical segment 200 biases cylindrical tab 415 radially against outside surface 445 of distal cylindrical segment 200, thereby frictionally maintaining distal cylindrical segment 200 in a desired position with respect to proximal cylindrical segment 200 (the contacting surfaces of cylindrical tab 415 and/or proximal cylindrical segment 200 may be provided with additional features to aid in the frictional bond, such as, for example, surface texturing). Outside surface 445 of distal cylindrical segment 200 is provided with stopper tabs 450a, 450b, which engage with proximal leading face 460 of cylindrical tab 415 to prevent distal cylindrical segment 200 from sliding to far distally and/or completely out of locking nut 405 when locking nut 405 is loosened partially with respect to proximal cylindrical segment 200. Stopper tabs 450a, 450b include detents 455a, 455b structured to mate with respective transverse holes 462a, 462b of distal cylindrical segment 200 to maintain stopper tabs 450a, 450b rigidly in proper position (both rotationally and/or longitudinally) with respect to outside surface of 445 of distal cylindrical segment 200. In an alternative embodiment, stopper tabs 450a, 450b are maintained in position using other means, such as glue, screws, nuts, etc. In yet another embodiment of the present invention, stopper tabs 450a, 450b are formed integrally with distal cylindrical segment 200 or, alternatively, are dispensed with entirely.

[0027] Referring now to FIGS. 5a and 5b, there is seen perspective views of attachment member 115. Attachment member 115 is structured to permit an accessory 120 (such as a cleaning accessory 120) to be removably attached to tool 100. For this purpose, attachment member 115 includes a threaded receptacle 465 for rigidly mating with outer screw threads 435 of cylindrical segment 200e (i.e., the cylindrical segment 200 positioned most distally from proximal end 125 of extension pole 110) and a female clip member 470. Female clip member 470 is structured to removably mate with male clip member 475 of accessory 120 in a manner known in the art (see FIG. 5b). In this way, tool 100 may be used with various different types of accessories 120, depending on the application. For example, when tool 100 is to be used to clean an aquarium, accessory 120 may include, for example, a fiber pad, such as a pad for cleaning algae, a sponge, a scraper, etc. In an alternative embodiment shown in FIG. 6, accessory 120 includes a receiving slot 480 for removably mating with any of various operating tips 485, such as a scraper, a sponge, a fiber pad, etc. It should be appreciated that, although the various embodiments described herein include female and male clip members 470, 475 to facilitate removable attachment of accessory 120 to tool 100, a person of ordinary skill in the art would recognize other structures and/or manners for removably attaching accessory 120 to tool 100, and that the present invention as a whole is not intended to be limited by or to any specific type of structure or manner for doing so.

[0028] While the present invention has been illustrated by description of various embodiments and while those embodiments have been described in considerable detail, it is not the intention of applicant to restrict or in any way limit the scope of the invention to such details. Additional advantages and modifications will readily appear to those skilled in the art. The invention in its broader aspects is therefore not limited to the specific details and illustrative examples shown and described. Accordingly, departures may be made from such details without departing from the spirit or scope of the invention.
