This disclosure relates generally to the field of chainsaw maintenance tools.
Currently there are a number of solutions for removing nuts, screws, and sparkplugs from chainsaws. Some of these solutions attempt to combine various tools into one compact tool, but these solutions fail to meet the needs of the industry because they still require tool removal and reattachment especially when bolts or sparkplugs are removed. Other solutions attempt to eliminate the need for tool removal when removing or reattaching bolts by using various ratcheting mechanisms but these solutions are similarly unable to meet the needs of the industry because they require the use of a separate tool for removal of screws.
It would be desirable to have a chainsaw repair tool that allows for quick, and efficient removal of bolts, spark plugs, and screws. Furthermore, it would also be desirable to have a chainsaw repair tool that did not need to be removed and reattached when the maximum amount of circular movement in the desired direction is reached. Therefore, there currently exists a need in the industry for a ratcheting scrench.
The disclosure presented herein relates to a ratcheting scrench. The preceding and following embodiments and descriptions are for illustrative purposes only and are not intended to limit the scope of this disclosure. Other aspects and advantages of this disclosure will become apparent from the following detailed description.
Certain terminology and derivations thereof may be used in the following description for convenience in reference only, and will not be limiting. For example, words such as “upward,” “downward,” “left,” and “right” would refer to directions in the drawings to which reference is made unless otherwise stated. Similarly, words such as “inward” and “outward” would refer to directions toward and away from, respectively, the geometric center of a device or area and designated parts thereof. References in the singular tense include the plural, and vice versa, unless otherwise noted.
The disclosed device is unique when compared with other known devices and solutions because it provides the ability to remove sparkplugs and bolts without removing and reattaching the tool once the maximum amount of circular movement in the desired direction is reached. Furthermore, the device allows the removal and reattachment of bolts, screws, and sparkplugs without the necessity of carrying around multiple tools saving chainsaw users both time and money.
The disclosed device is unique in that it is structurally different from other known devices or solutions. More specifically, the device is unique due to the presence of: (1) a ratcheting mechanism; (2) a spark plug and bolt removing mechanism; and (3) a screw removing mechanism all in one device.
Embodiments of the present disclosure are described in detail below with reference to the following drawings. These and other features, aspects, and advantages of the present disclosure will become better understood with regard to the following description, appended claims, and accompanying drawings. The drawings described herein are for illustrative purposes only of selected embodiments and not all possible implementations and are not intended to limit the scope of the present disclosure. Also, the drawings included herein are considered by the applicant to be informal.
In the Summary above and in this Detailed Description, and the claims below, and in the accompanying drawings, reference is made to particular features (including method steps) of the invention. It is to be understood that the disclosure of the invention in this specification includes all possible combinations of such particular features. For example, where a particular feature is disclosed in the context of a particular aspect or embodiment of the invention, or a particular claim, that feature can also be used, to the extent possible, in combination with and/or in the context of other particular aspects and embodiments of the invention, and in the invention generally.
The term “comprises” and grammatical equivalents thereof are used herein to mean that other components, ingredients, steps, among others, are optionally present. For example, an article “comprising” (or “which comprises”) components A, B and C can consist of (i.e., contain only) components A, B and C, or can contain not only components A, B, and C but also contain one or more other components.
Where reference is made herein to a method comprising two or more defined steps, the defined steps can be carried out in any order or simultaneously (except where the context excludes that possibility), and the method can include one or more other steps which are carried out before any of the defined steps, between two of the defined steps, or after all the defined steps (except where the context excludes that possibility).
The term “at least” followed by a number is used herein to denote the start of a range beginning with that number (which may be a range having an upper limit or no upper limit, depending on the variable being defined). For example, “at least 1” means 1 or more than 1. The term “at most” followed by a number (which may be a range having 1 or 0 as its lower limit, or a range having no lower limit, depending upon the variable being defined). For example, “at most 4” means 4 or less than 4, and “at most 40%” means 40% or less than 40%. When, in this specification, a range is given as “(a first number) to (a second number)” or “(a first number)-(a second number),” this means a range whose limit is the second number. For example, 25 to 100 mm means a range whose lower limit is 25 mm and upper limit is 100 mm.
Disclosed is a ratcheting scrench, which is made up of the following components: (1) an elongating shaft, (2) a nut and spark plug removing end, and (3) a screw removing end. The nut and spark plug removing end is further made up of (1) a socket designed to fit nuts, (2) a socket designed to fit spark plugs and (3) a ratcheting mechanism.

As can be seen in
Tubular bodies 201 and 203 can be various lengths but preferably allow the head of the bolt to extend into ratcheting mechanism 205. Various ratcheting mechanisms known in the art would work with the invention. In one embodiment, shown in
Pawl 611 sits in recessed opening 603 between driving member 605 and switch button 608 and includes toothed portion 613 and a recessed portion 614. Toothed portion 613 can reversibly engage with driving member 605.
Pressing member 615 biased by elastic member 616 is received in pressing member receptacle 612. The first end of pressing member 615 biased by elastic element 616 fits into recessed portion 614 of pawl 610 which causes the toothed portion 613 of pawl 610 and the exterior toothed portion 607 of driving portion 606 to engage. Received into fixing member receptacle 613 is fixing member 617 which can press against the pawl if the pawl malfunctions. Switch button 608, part of which protrudes outside of tubular members 201 and 203 can be pivoted relative to elongating shaft 101 to change the driving direction and non-driving direction of ratcheting mechanism 205. Specifically when elongating shaft 101 is rotated in the driving direction a fastener coupled with driving portion 606 of driving member 605 rotates jointly with elongating shaft 101 in the driving direction. When elongating shaft 101 is rotated in the non-driving direction the fastener and driving member 605 remain still.
While preferred and alternate embodiments have been illustrated and described, as noted above, many changes can be made without departing from the spirit and scope of the ratcheting scrench. Accordingly, the scope of the ratcheting scrench is not limited by the disclosure of these preferred and alternate embodiments. Instead, the scope of the invention is to be determined entirely by reference to the claims. Insofar as the description above and the accompanying drawings (if any) disclose any additional subject matter that is not within the scope of the claims below, the inventions are not dedicated to the public and Applicant hereby reserves the right to file one or more applications to claim such additional inventions.
The reader's attention is directed to all papers and documents which are filed concurrently with this specification and which are open to public inspection with this specification, and the contents of all such papers and documents are incorporated herein by reference.
All the features disclosed in this specification (including any accompanying claims, abstract, and drawings) may be replaced by alternative features serving the same, equivalent or similar purpose, unless expressly stated otherwise. Thus, unless expressly stated otherwise, each feature disclosed is one example of a generic series of equivalent or similar features.
Any element in a claim that does not explicitly state “means for” performing a specified function, or “step for” performing a specific function is not to be interpreted as a “means” or “step” clause as specified in 35. U.S.C. § 112 ¶6. In particular, the use of “step of” in the claims herein is not intended to invoke the provisions of U.S.C. § 112 ¶ 6.
