This disclosure relates to tools for holding at least a portion of a fastener in place during assembly or removal. More specifically, this disclosure relates to tools for holding at least a portion of a fastener in place during assembly or removal, the tools being able to compensate for a height of the portion of the fastener.
Removing assembled portions of a fastener assembly (e.g., a head or nut of a threaded fastener assembly) can be as simple as engaging a fastener removal tool (e.g., a wrench or socket) to the head or the nut and rotating the tool until the fastener assembly has been loosened and disassembled. In some aspects, however, it can be beneficial or necessary to hold one side of the fastener assembly while the other side is engaged with the fastener removal tool. While it can be convenient for a user (e.g., a mechanic) to directly hold the one side of the fastener assembly with his or her hand, direct contact with the one side of the fastener assembly while the other side is engaged with the fastener removal tool, which often produces high RPM (revolutions per minute, i.e., a rotational speed of the fastener removal tool), high torque, and/or high temperature in the fastener assembly, can result in a safety risk to the mechanic.
It is to be understood that this summary is not an extensive overview of the disclosure. This summary is exemplary and not restrictive, and it is intended to neither identify key or critical elements of the disclosure nor delineate the scope thereof. The sole purpose of this summary is to explain and exemplify certain concepts of the disclosure as an introduction to the following complete and extensive detailed description.
In one aspect, disclosed is a tool comprising: a structural member defining a hub and at least one arm extending from the hub; and a mounting fastener secured to the structural member and configured to hold itself in place against a mating surface. In a related aspect, disclosed is a tool comprising: a structural member defining a hub and at least one arm extending from the hub; and a mounting fastener secured to the arm of the structural member at a position distal from the hub and configured to automatically adjust to and hold itself in place against a non-flat mating surface of a structure, the tool configured to contact and maintain a position of a fastener assembly in a direction of an axis of the fastener assembly.
In a further aspect, disclosed is a tool comprising: a mounting fastener defining a cavity configured to hold itself in place against a mating surface; and a holding fastener adjustably secured to and extending through the mounting fastener and into the cavity.

In a related aspect, disclosed is a method of using a tool, the method comprising: aligning one of a spacer and a holding fastener of the tool with a first connecting portion of a fastener assembly, the fastener assembly configured to secure a first structure to a second structure, the first structure being a wearable blade; and securing a mounting fastener of the tool to the first structure, the mounting fastener configured to automatically adjust to and hold itself in place against a non-flat mating surface of the first structure.
Various implementations described in the present disclosure may comprise additional systems, methods, features, and advantages, which may not necessarily be expressly disclosed herein but will be apparent to one of ordinary skill in the art upon examination of the following detailed description and accompanying drawings. It is intended that all such systems, methods, features, and advantages be included within the present disclosure and protected by the accompanying claims. The features and advantages of such implementations may be realized and obtained by means of the systems, methods, features particularly pointed out in the appended claims. These and other features will become more fully apparent from the following description and appended claims or may be learned by the practice of such exemplary implementations as set forth hereinafter.
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate several aspects of the disclosure and together with the description, serve to explain various principles of the disclosure. The drawings are not necessarily drawn to scale. Corresponding features and components throughout the figures may be designated by matching reference characters for the sake of consistency and clarity.
The present disclosure can be understood more readily by reference to the following detailed description, examples, drawings, and claims, and their previous and following description. However, before the present devices, systems, and/or methods are disclosed and described, it is to be understood that this disclosure is not limited to the specific devices, systems, and/or methods disclosed unless otherwise specified, as such can, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular aspects only and is not intended to be limiting.
The following description is provided as an enabling teaching of the present devices, systems, and/or methods in their best, currently known aspect. To this end, those skilled in the relevant art will recognize and appreciate that many changes can be made to the various aspects described herein, while still obtaining the beneficial results of the present disclosure. It will also be apparent that some of the desired benefits of the present disclosure can be obtained by selecting some of the features of the present disclosure without utilizing other features. Accordingly, those who work in the art will recognize that many modifications and adaptations to the present disclosure are possible and can even be desirable in certain circumstances and are a part of the present disclosure. Thus, the following description is provided as illustrative of the principles of the present disclosure and not in limitation thereof.
As used throughout, the singular forms “a,” “an” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to a quantity of one of a particular element can comprise two or more such elements unless the context indicates otherwise. In addition, any of the elements described herein can be a first such element, a second such element, and so forth (e.g., a first widget and a second widget, even if only a “widget” is referenced).
Ranges can be expressed herein as from “about” one particular value, and/or to “about” another particular value. When such a range is expressed, another aspect comprises from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent “about” or “substantially,” it will be understood that the particular value forms another aspect. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint.
For purposes of the current disclosure, a material property or dimension measuring about X or substantially X on a particular measurement scale measures within a range between X plus an industry-standard upper tolerance for the specified measurement and X minus an industry-standard lower tolerance for the specified measurement. Because tolerances can vary between different materials, processes and between different models, the tolerance for a particular measurement of a particular component can fall within a range of tolerances.
As used herein, the terms “optional” or “optionally” mean that the subsequently described event or circumstance may or may not occur, and that the description comprises instances where said event or circumstance occurs and instances where it does not.
The word “or” as used herein means any one member of a particular list and also comprises any combination of members of that list. The phrase “at least one of A and B” as used herein means “only A, only B, or both A and B”; while the phrase “one of A and B” means “A or B.”
To simplify the description of various elements disclosed herein, the conventions of “left,” “right,” “front,” “rear,” “top,” “bottom,” “upper,” “lower,” “inside,” “outside,” “inboard,” “outboard,” “horizontal,” and/or “vertical” may be referenced. Unless stated otherwise, “front” describes that end of a vehicle 600 (shown in
Alternatively, the tool 100 can be described below on the basis of a coordinate axis of X-Y-Z directions shown in the figures. An X-axis direction can be referred to as a left-right or horizontal direction. For example, as shown in
In one aspect, a tool and associated methods, systems, devices, and various apparatuses are disclosed herein. In one aspect, the tool can be a fastener position holding tool and can comprise a magnet and a holding fastener.
The tool 100 can comprise a structural member 110, a holding fastener 140, and at least one tool mounting fastener 170. In some aspects, the structural member 110 can be a bar or plate. More specifically, the structural member 110 can comprise or define a hub 120 and one or more arms 130a,b, each of which can extend from the hub 120 in a radial direction with respect to an axis 101 of the tool 100 or an axis 141 of the holding fastener 140. As shown, the structural member 110 can comprise the two arms 130a,b, each of which can extend from the hub 120 in the radial direction and in a longitudinal direction 113. In some aspects, each of the arms 130a,b of the structural member 110 and any portions of the tool 100 can be radially symmetric about one or both of the axes 101,141. As shown, the structural member 110 can define a length L in the longitudinal direction 113 and a width W in a transverse direction 114, and a thickness T (shown in
The holding fastener 140 can be adjustably secured to the structural member 110 and can extend through the hub 120 of the structural member 110. The holding fastener 140 can define a first end 145 (shown in
The main portion 150 of the holding fastener 140 can comprise a shaft 152 and a head 154, which can comprise or define a knob. The head 154 and, more specifically, the knob can define a plurality of lobes or ridges extending radially outward to ease rotation of and tightening of the holding fastener 140 with a hand of a user of the tool 100. As shown, the head 154 can define seven lobes, although in other aspects any number of lobes or ridges can be defined in the head 154. In any case, the head 154 can define a diameter that is greater than a diameter of the shaft 152 and which can vary with respect to an axial position along the axis 141. The locking portion 160 of the holding fastener 140 can comprise a locking fastener 162, which can comprise or can be a nut. In some aspects, the locking fastener 162 can be a locking nut or a lock nut. In some aspects, any individual portion of the holding fastener 140 can be formed from multiple materials or components. In other aspects, the holding fastener 140 or any individual portion thereof can be formed monolithically, i.e., as a single piece of material.
The locking portion 160 of the holding fastener 140 can be adjustably positioned adjacent to the structural member 110 and can receive the shaft 152 of the main portion 150. The axis 141 of the holding fastener 140 and an axis of the shaft 152 can be angled with respect to the structural member 110. More specifically, the axis 141 and the axis of the shaft 152 can be angled at 90 degrees with respect to the structural member 110. The locking portion 160 can be configured to lock a rotational position of the holding fastener 140 with respect to the structural member 110. As shown, the locking portion 160 can be a hex nut.
The tool 100 can comprise a plurality of mounting fasteners 170a,b, which can be synonymous with the mounting fastener 170. One or more of the mounting fasteners 170a,b can, in some aspects, comprise a magnet or magnetized material configured to be magnetically attracted to a ferromagnetic material. Such a magnet can be a rare-earth magnet such as, for example and without limitation, neodymium. More specifically, the magnet can be an NdFeB magnet made from an alloy of neodymium, iron, and boron. For example and without limitation, as shown, the magnet can define a diameter of one inch and a height of 0.315 inches and can comprise a magnet 820 (shown in
In some aspects, each of the mounting fasteners 170a,b can comprise an electromagnet, which can be activated through the flow of current through a coil contained therein. By adjusting the amount of current or turning off the current, the magnetic force can be increased or decreased or removed altogether such as, for example and without limitation, during removal of the tool 100 from a mating structure such as the bucket 610 (shown in
The mounting fastener 170a,b need not comprise a magnet or magnetized material. In other aspects, one or more of the mounting fasteners 170a,b can comprise a suction cup or other fastener able to be secured to a surface such as a lower surface of the blade 650 of the bucket 610. In some aspects, the mounting fastener 170a,b does not require a mechanical connection. In some aspects, the mounting fastener 170a,b can comprise one or more fasteners making a mechanical connection. In some aspects, for example, each of the mounting fasteners 170a,b can comprise a fastener (not shown) such as a bolt or screw extending into or through the bucket 610 or other mating structure to secure the mounting fastener 170a,b to the bucket 610 or other mating structure. In some aspects, one portion of a mounting fastener such as a hook portion of a hook-and-loop fastener can be secured to the mating structure and a second portion of the mounting fastener such as a loop portion of the hook-and-loop fastener can be secured to the structural member 110.
Each of the mounting fasteners 170a,b can be secured to the structural member 110 with a fastener 190, which can comprise a first connecting portion 192 and a second connecting portion 194. The first connecting portion 192 can be any suitable fastener including one containing a shaft such as, for example and without limitation, a bolt or a screw or a pin. The second connecting portion 194 can be any suitable fastener including one defining a hole for receiving the shaft of the first connecting portion 192 such as, for example and without limitation, a nut or cotter pin. As shown, each of the fasteners 190 can be angled at 90 degrees with respect to the structural member 110. At the same time, however, each of the fasteners 190 can be free to rotate with respect to the default orientation—and sufficient play can be provided in the openings 398 (shown in
A spacer 180 can be positioned between the structural member 110 and the corresponding mounting fastener 170a,b. As shown, the spacer 180 can define an annular shape and can be an O-ring. The spacer 180 can be at least one of an elastic and a compressible material and, as such, can be configured to allow movement of the mounting fastener 170a,b with respect to the structural member 110. More specifically, the spacer 180 can be configured to allow one of rotation of the mounting fastener 170a,b about an axis orthogonal to the corresponding axis 171a,b and translation of the mounting fastener 170a,b along the corresponding axis 171a,b of the of the mounting fastener 170a,b in an adjustment direction corresponding to the Z-axis (shown in
A separate shim (not shown) defining a desired thickness corresponding to the gap G can be positioned between the structural member 110 and the first surface 172 of the corresponding mounting fastener 170a to set the gap G therebetween. By adjusting the gap G up or down, a connection between the mounting fastener 170a,b and the structural member 110 can be made generally more or less flexible to adjust more readily to surfaces against which the tool 100 may be attached. For example and without limitation, the gap G can be set to 1/16 inch.
Upon tightening of the locking portion 160 of the holding fastener 140 and, more specifically, the locking fastener 162 against a surface of the structural member 110 such as, for example and without limitation, a surface of the second side 118, each of a rotational position and an axial position of the holding fastener 140 can be fixed with respect to the structural member 110. The shaft 152 of the holding fastener 140 is shown not yet extending beyond a surface of the first side 117 of the structural member 110.
In some aspects, as shown, the second connecting portion 194 of the fastener 190 can be a lock nut such as, for example and without limitation, a nylon lock nut resisting rotation about the first connecting portion 192 of the fastener 190 by a friction fit between an insert defined in a bore of the nut and formed from a resin such as, for example and without limitation, a polyamide such as nylon. In other aspects, the fastener 190 can comprise a washer (not shown), which can be positioned between the second connecting portion 194 and the structural member 110. The second connecting portion 194 can facilitate setting of the gap G (shown in
In some aspects, as shown, the spacer 180 can be a sheet or can be monolithic and can, in any case, extend across the structural member 110 and between each of the mounting fasteners 170a,b and the structural member 110. The spacer 180 can, in some aspects, define a substantially rectangular shape. In some aspects, a portion of the spacer 180 facing a head of the first connecting portion 692 (shown in
The main opening 348 can be aligned with the axes 101,141 of the tool 100 and the holding fastener 140, respectively. The openings 398 can be offset from the first end 115 and the second end 116, respectively, by a distance such as, for example and without limitation, one half inch. In some aspects, each of the shaft 152 of the main portion 150 and the locking fastener 162 of the locking portion 160 can be threaded. In other aspects, the shaft 152 or, more generally, the holding fastener 140, can be otherwise configured to move and be fixed, with or without indexing, with respect to the structural member 110. In some aspects, as shown, the washer 166 can be a flat or smooth washer.

Returning to
As shown, the first end 145 of the holding fastener 140 can be in contact with the fastener assembly 690 and, more specifically, the first connecting portion 692 to hold the first connecting portion 692 in place. The holding fastener 140 can hold the first connecting portion 692 in place even when the second connecting portion 694 is not present or when the second connecting portion 694 is loosened or even when a force pushing against a flange 896 of the second connecting portion 694 towards an outer surface 811 of the main portion 810 of the bucket 610 tends to push the first connecting portion 692 outward or downward or otherwise in a direction tending to separate the tool 100 from the mating structure. More specifically, the tool 100 can be configured to contact and maintain a position of the fastener assembly 690 in a direction of the axis 801 of the fastener assembly 690. The first end 145 of the holding fastener 140 can be brought in contact with the fastener assembly 690 by adjusting a distance 807 between the structural member 110 and a nearest portion, e.g., a head, of the first connecting portion 692 of the fastener assembly 690. More specifically, either or both of the axes 101,141 can be brought into alignment or substantial alignment with the axis 801. The ability to adjust the distance 807 can facilitate use of the tool 100 with a variety of different bolt sizes and degrees of wear, especially to a head of the first connecting portion or bolt 692. In some cases, for example, the head of the first connecting portion 692 can be completely worn and require greater extension of the first end 145 of the holding fastener 140. In some aspects, the fastener assembly 690 can comprise a low-profile (e.g., countersunk or otherwise short or flat-top) head, which the tool 100 and, more specifically, the distance 807 can also be adjusted to accommodate. The tool 100 and, more specifically, the distance 807 can also be adjusted to accommodate variance in a depth of the recessed portion 758.
In some aspects, the spacer 180 can be placed on the working surface 174 of the mounting fastener 170, e.g., with an adhesive, to facilitate conformance of the working surface 174 with the mating surface of the bucket 610. More specifically, in some aspects, a circular spacer 180 could be secured to the working surface 174 shown in
A method of using the tool 100 can comprise brushing or otherwise cleaning a surface of the areas of a first structure and a second structure joined by the one or more fastener assemblies 690. The method can comprise aligning the axis 141 of the holding fastener 140 of the tool 100 with the first connecting portion 692 of the fastener assembly 690, in which case the fastener assembly 690 can secure a first structure to a second structure. The method can comprise securing the mounting fastener 170—or the mounting fasteners 170a,b, as also in the case of any other structures or method steps disclosed herein—of the tool 100 to the first structure, in which case the mounting fastener 170 can be configured to hold itself in place against a mating surface of the first structure (e.g., the surface 852 of the blade 650). In some aspects, the method can comprise adjusting a position of the holding fastener 140 with respect to the structural member 110 joining the holding fastener 140 to the mounting fastener 170 to prevent dislocation of the first connecting portion 692 from the first structure. The method of adjusting the position of the holding fastener 140 can comprise adjusting and, more specifically, rotating the holding fastener until the first end 145 thereof contacts the first connecting portion 692 of the fastener assembly 690. In some aspects, no holding fastener 140 and therefore no adjusting thereof is necessary. More specifically, the method can comprise contacting the first connecting portion 692 of the fastener assembly 690 with the tool 100. In some aspects, contacting the first connecting portion 692 of the fastener assembly 690 with the tool 100 can comprise contacting the fastener assembly 690 with the spacer 1110. In some aspects, contacting the first connecting portion 692 of the fastener assembly 690 with the tool 100 can comprise compressing the spacer 1110. In some aspects, contacting the first connecting portion 692 of the fastener assembly 690 with the tool 100 can comprise directly contacting the first connecting portion 692 with the structural member 110.
The method can comprise removing the second connecting portion 694 of the fastener assembly 690 from the first connecting portion 692 to disassemble the fastener assembly 690, which again can comprise both of the first connecting portion 692 and the second connecting portion 694. The method can comprise removing the tool 100 by applying the force F to a portion of the tool 100. More specifically, the method of removing the tool 100 can comprise applying the force F to a portion of the tool 100 in a direction that is angled with respect to an axis 101 of the tool 100, which can include rocking the tool with a side force. In some aspects, removing the tool 100 can comprise sliding the tool 100 across the mating surface (e.g., the surface 852) until one of more of the mounting fasteners 170a,b of the tool 100 disengage from the mating surface. In some aspects, removing the tool 100 can comprise tightening the holding fastener of the tool 100 to push against a portion of the mating surface and/or the fastener assembly and thereby lift the tool 100 from the mating surface. The method can comprise installing a new first structure such as a new blade 650 and inserting each of a plurality of new first connecting portions or bolts 692 into corresponding holes in the bucket 610. The method can comprise installing the tool 100 at each position of one of the first connecting portions 692 and tightening, hands-free, the second connecting portion 694 from the top or opposite side. The method can therefore facilitate safe and consistent removal of any number of old fastener assemblies 690, installation of any number of new fastener assemblies 690, or both removal and installation. Because the tool 100 and not a user's hand holds the first connecting portion 692 in place, the user can avoid the impact and potential consequences (e.g., injury) of fatigue, insufficient training, or poor judgment on the removal and replacement process. Including in each of the above uses, the tool 100 can effectively be used to facilitate replacement of bolts such as the fastener assemblies 690 by retaining such bolts in position so that they can be extracted once disassembly is complete.
In other aspects, the tool need not hold a fastener in place but can hold a small piece of magnetic or other material during a fabrication process such as one involving drilling of a hole through a piece of sheetmetal material. A method of using the tool 100 to facilitate fabrication of a sheetmetal material can comprise aligning an axis 141 of the holding fastener 140 and specifically an axis of the tip 310 (shown in
The components of the tool 100 and any portion thereof can be formed from any one of a variety of materials selected based on their strength characteristics, weight, and cost. In some aspects, it will be beneficial to select a material with sufficient strength to avoid deformation, corrosion, or fatigue in use. In some aspects, for example, the structural member 110 and any portion of one or more of the holding fastener 140, the mounting fastener(s) 170, the fastener(s) 190, and any other portion of the tool 100 can be formed from a material such as steel or aluminum, which can be cast, molded, and/or machined to produce any of the features disclosed herein. In some aspects, the tool 100 or portions thereof can be formed from a zinc-plated, galvanized, or stainless steel or other corrosion-resistant material or from a material such as carbon or tool steel that is less corrosion-resistant. In other aspects, another material can be used for any of the parts such as, for example and without limitation, a metal other than steel, a composite material, or a polymer resin—including of the fiber-reinforced kind. In some aspects, as shown, the tool 100 or portions thereof can be formed from sheet metal through traditional sheet metal forming processes. In other aspects, the structure can be formed from a powder in a three-dimensional printing process, from pellets in a molding process, or from another raw material and/or forming process. In some aspects, components such as the spacer 180 (shown in
One should note that conditional language, such as, among others, “can,” “could,” “might,” or “may,” unless specifically stated otherwise, or otherwise understood within the context as used, is generally intended to convey that certain aspects include, while other aspects do not include, certain features, elements and/or steps. Thus, such conditional language is not generally intended to imply that features, elements and/or steps are in any way required for one or more particular aspects or that one or more particular aspects necessarily comprise logic for deciding, with or without user input or prompting, whether these features, elements and/or steps are included or are to be performed in any particular aspect.
It should be emphasized that the above-described aspects are merely possible examples of implementations, merely set forth for a clear understanding of the principles of the present disclosure. Any process descriptions or blocks in flow diagrams should be understood as representing modules, segments, or portions of code which comprise one or more executable instructions for implementing specific logical functions or steps in the process, and alternate implementations are included in which functions may not be included or executed at all, may be executed out of order from that shown or discussed, including substantially concurrently or in reverse order, depending on the functionality involved, as would be understood by those reasonably skilled in the art of the present disclosure. Many variations and modifications may be made to the above-described aspect(s) without departing substantially from the spirit and principles of the present disclosure. Further, the scope of the present disclosure is intended to cover any and all combinations and sub-combinations of all elements, features, and aspects discussed above. All such modifications and variations are intended to be included herein within the scope of the present disclosure, and all possible claims to individual aspects or combinations of elements or steps are intended to be supported by the present disclosure.
