The background description provided herein is for the purpose of generally presenting the context of the disclosure. Work of the presently named inventors, to the extent it is described in this background section, as well as aspects of the description that may not otherwise qualify as prior art at the time of filing, are neither expressly nor impliedly admitted as prior art against the present disclosure. Unless otherwise indicated herein, the approaches described in this section are not prior art to the claims in the present disclosure and are not admitted to be prior art by inclusion in this section.
It is often advantageous to mount certain tools on the end of an extension pole to reach inconvenient or inaccessible areas without the use of ladders, scaffolding, and the like. The most widely recognized application of such tool mounting extension poles is in connection with paint rollers, paint brushes, window washing squeegees, etc. Traditional tool mounting extension poles have threaded bores that allow a user to screw on tools and additional pole sections. The threaded bores generally adhere to industry-accepted size and thread pattern, so that tools of various types and manufacturers may be substantially served by extension poles of various types and manufacturers. Unfortunately, once screwed onto the end of a traditional extension pole, a tool is often susceptible to undesirable and inadvertent loosening and unscrewing during use. Moreover, when tightly installed, the tool is substantially fixed in position, making attachment, detachment, and use of the tool awkward and difficult.
An extension pole and tool holder apparatus is described including first, second and third rods, with a tool typically being mounted to the third rod. One aspect of the invention includes a first rod that has a distal end and a proximal end, and a first rod aperture extending from the distal end toward the proximal end. The first rod aperture also includes a transversely-extending aperture portion that is longitudinally spaced from the distal end. The second rod has distal and proximal ends, the second rod being disposed in a telescoping, longitudinally-moveable arrangement with respect to the first rod. The second rod typically has a second rod aperture with a longitudinally-extending aperture portion extending from the distal end toward the proximal end. The third rod has a protruding member extending transversely outwardly therefrom, the third rod being mountable within the first and second rods such that the protruding member is trapped within the transversely-extended aperture portion of the first rod aperture and the longitudinally-extended aperture portion of the second rod aperture.
Another aspect of the invention provides an extension pole and tool holder apparatus including first, second and third substantially cylindrical rods, each of which includes a distal and proximal end. The first rod includes a first rod aperture extending from the distal end toward the proximal end, the first rod aperture including a longitudinally-extending portion and a circumferentially-extending portion, wherein the longitudinally-extending portion is at the distal end of the first rod, and the circumferentially-extending portion extends from a proximal end of the longitudinally-extending portion. The second rod has a second rod aperture extending from the distal end toward the proximal end, the second rod aperture comprising a circumferentially-extending portion and a longitudinally-extending portion, wherein the circumferentially-extending portion is at the second rod distal end and the longitudinally-extending portion extends longitudinally from a proximal end of the circumferentially-extending portion. The third rod has a protruding member extending radially outwardly from each side thereof, the third rod being mountable within the first and second rod such that the protruding member is trapped within the circumferentially-extended portion of the first rod aperture and the longitudinally-extended portion of the second rod aperture.
Yet another aspect of the invention provides an extension pole and tool holder apparatus with first, second and third substantially cylindrical rods, the first rod including a first rod aperture extending from the distal end toward the proximal end. The first rod aperture includes a longitudinally-extending portion and a circumferentially-extending portion, wherein the longitudinally-extending portion is at the distal end of the first rod, and the circumferentially-extending portion is disposed proximally of the distal end. The second rod is disposed in a telescoping arrangement with the first rod and is biased in a distal direction with respect to the first rod. The second rod includes a second rod aperture extending from the distal end toward the proximal end, the second rod aperture including a circumferentially-extending portion and a longitudinally-extending portion, wherein the circumferentially-extending portion is at the second rod distal end. It also includes a locking collar mounted to the outermost of the first and second rods, the locking collar being mounted to a radially-inwardly extending locking assembly. The collar is rotatable in a first direction to lock the relative position of the first and second rods with respect to each other, and rotatable in a second direction to unlock the relative position of the first and second rods with respect to each other. The third rod includes a protruding member extending radially outwardly therefrom, the third rod being mountable within the first and second rods such that the protruding member is trapped within the circumferentially-extended portion of the first rod aperture and the longitudinally-extended portion of the second rod aperture.
Subject matter is particularly pointed out and distinctly claimed in the concluding portion of the specification. The foregoing and other features of the present disclosure will become more fully apparent from the following description and appended claims, taken in conjunction with the accompanying drawings. Understanding that these drawings depict only several embodiments in accordance with the disclosure and are, therefore, not to be considered limiting of its scope, the disclosure will be described with additional specificity and detail through use of the accompanying drawings, in which:
Reference will now be made to the drawings wherein like numerals refer to like parts throughout. For ease of description, the components of embodiments of the present disclosure are described in the normal (upright) operating position, and terms such as upper, lower, horizontal, etc., are used with reference to this position. It will be understood, however, that the components of embodiments of the present disclosure may be manufactured, stored, transported, used, and sold in an orientation other than the position described.
Figures illustrating the components of embodiments of the present disclosure show some conventional mechanical elements that may be known and that may be recognized by one skilled in the art. The detailed descriptions of such elements that are not necessary to an understanding of the disclosure, and accordingly are herein presented only to the degree necessary to facilitate an understanding of the novel features of the present disclosure.
As used herein and in the appended claims, the term “comprising” is inclusive or open-ended and does not exclude additional unrecited elements, compositional components, or method steps. Accordingly, the term “comprising” encompasses the more restrictive terms “consisting essentially of” and “consisting of.”
It must be noted that, as used in this specification and the appended claims, the singular forms “a,” “an,” and “the” include plural references unless the content clearly dictates otherwise. Similarly, the use of substantially any plural terms herein may be translated by those having skill in the art from the plural to the singular as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.
In those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “an apparatus having at least one of A, B, and C” would include but not be limited to apparatuses that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”
As will be understood by one skilled in the art, for any and all purposes, such as in terms of providing a written description, all ranges disclosed herein also encompass any and all possible subranges and combinations of subranges thereof. Any listed range can be easily recognized as sufficiently describing and enabling the same range being broken down into at least equal halves, thirds, quarters, fifths, tenths, etc. As a non-limiting example, each range discussed herein can be readily broken down into a lower third, middle third and upper third, etc. As will also be understood by one skilled in the art, all language such as “up to,” “at least,” “greater than,” “less than,” and the like include the number recited and refer to ranges which can be subsequently broken down into subranges as discussed above. Finally, as will be understood by one skilled in the art, a range includes each individual member. Thus, for example, a group having 1-3 elements refers to groups having 1, 2, or 3 elements. Similarly, a group having 1-5 elements refers to groups having 1, 2, 3, 4, or 5 elements, and so forth.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which embodiments of the present invention pertain. Although a number of methods and materials similar or equivalent to those described herein can be used in the practice of the present invention, the preferred materials and methods are described herein.
A tool-mounting section 70, which may be inserted at distal end 2 of extension pole and tool holder 10, is also depicted. Tool-mounting section 70 typically has radially protruding members 72 (also depicted in
As depicted in
Aperture 22 is disposed at the distal end of the handle member 20. As shown best in FIGS. 2 and 3B-C, handle member aperture 22 includes a longitudinally-extending portion 23 and a circumferentially-extending portion 25, the longitudinally-extending portion 23 being at the distal end of handle member 20, and the circumferentially-extending portion 25 extending circumferentially from the proximal end of the longitudinally-extending portion 23. Or, stated another way, the longitudinally-extending portion 23 is at the distal end of handle member 20, and the circumferentially-extending portion 25 is proximally spaced from the distal end. Another way to describe the circumferentially-extending portion 25 is that it is transversely-extending, for example if handle member 20 and retaining sleeve 30 are not cylindrical in configuration.
As shown best in FIGS. 2 and 3B-C, aperture 32 is disposed at the distal end of the retaining sleeve 30, and includes a circumferentially-extending portion 33 and a longitudinally-extending portion 37 that extends longitudinally from the proximal end of circumferentially-extending portion 33. Or, stated another way, retaining sleeve aperture 32 includes a circumferentially-extending portion 33 at the distal end of retaining sleeve 30, and a longitudinally-extending portion 37 that is contiguous with and extends longitudinally from one side of the proximal end of circumferentially-extending portion 33. In the depicted embodiment the longitudinally-extending portion 37 of retaining sleeve aperture 32 extends from the side of the retaining sleeve aperture that is remote from longitudinally-extending portion of the 23 of handle portion aperture 22. Again, another way to describe the circumferentially-extending portion 33 is that it is transversely-extending, particularly if handle member 20 and retaining sleeve 30 are not cylindrical in configuration.
It can be seen in
Handle member 20 and retaining sleeve 30 have the same longitudinal axis 21 and fit snugly but longitudinally slidably with respect to each other. In the depicted embodiment they would not be rotatable with respect to each other. In their initial positions shown in
Returning to
As shown best in
Also positioned within handle member 20 is a locking assembly extending into the handle member to facilitate locking of handle member 20 and retaining sleeve 30 with respect to each other. The locking member may be described as extending radially into handle member 20 if the handle member is cylindrical in configuration. In the depicted embodiment the locking assembly includes a pin assembly ring 60, shown best in
A radially-extending sleeve pin 36 is positioned within handle member 20 and retaining sleeve 30 as shown in FIGS. 2 and 4A-H. Locking collar 40 is positioned snugly but rotatably on retaining sleeve 30. Locking collar 40 includes a collar aperture 42 that extends entirely through the locking collar and is designed to receive a radially-extending locking collar pin 44. Locking collar pin 44 has a pair of spaced narrowed portions 44a and 44b to facilitate engagement of the locking collar pin in pin assembly ring 60.
As can be seen from
In order to assemble the depicted extension pole and tool holder 10, retaining sleeve 30 is slid over the handle member 20, and spring 50 is compressed until the distal edges of apertures 22 and 32 are axially aligned as shown in
As depicted in
In order to mount tool-mounting section 70 to handle member 20 and retaining sleeve 30, as shown in
