Description

INTRODUCTION

Field

Aspects of the present disclosure relate to a system, method, and apparatus for installing and retaining a fastener.

Background

Installing and retaining fasteners, such as breakaway fasteners and other types of nuts, are important parts of production and assembly processes. Conventional methods and apparatuses for installing and retaining fasteners are limited in their capability or may not be suitable for certain production processes, such as installing breakaway fasteners on an aircraft.

Breakaway fasteners are fasteners configured to have a portion break off, such as a wrenching element, when a predetermined torque is applied to the fastener. When a breakaway fastener is installed on, for example, an aircraft, the wrenching element of the fastener must be recovered to prevent foreign object debris (FOD) from being left in the aircraft. FOD is material or debris, such as the wrenching element of the fastener, that is alien to the aircraft and can damage the aircraft or may fall into a difficult-to-access area and would need to be recovered from that location in order to prevent potential future problems. Damage from FOD is a serious matter and may cost millions of dollars to repair, require unplanned maintenance, temporarily remove an otherwise operable aircraft from service, or result in loss of an aircraft. This same problem may happen across many domains, including when using fasteners on many types of vehicles.

Conventional methods for installing the breakaway fastener use a ratcheting socket wrench (referred to as a ratchet) and socket to tighten the fastener and do not provide a means for retaining the wrenching element of the fastener in the socket after the fastener is installed. If the wrenching element falls out of the socket, it must be recovered so it does not become FOD. Thus, installing breakaway fasteners, particularly in areas with limited space with little or no room to recover a wrenching element, may be challenging using conventional methods and apparatuses.

Accordingly, there is a need for an improved method and apparatus for installing and retaining a fastener. For example, there is a need to retain the fastener, or a wrenching element of the fastener, during and/or after installation.

DETAILED DESCRIPTION

Aspects of the present disclosure provide a method and an apparatus for installing and retaining a fastener such that the fastener, or a portion of the fastener, is retained during and/or after installation.

According to one aspect, the apparatus for retaining a fastener connects to a ratchet and a socket. The ratchet and socket (referred to as a ratcheting socket set) are used to install a fastener on a surface. For example, the fastener may be a breakaway fastener and may be installed on an aircraft. The breakaway fastener may comprise a collar that threads onto a bolt to secure the fastener to the aircraft. As above, breakaway fasteners are fasteners with a portion that “breaks away” from the rest of the fastener when a predetermined torque is applied. The portion that breaks away may be referred to as a wrenching element. Generally, a wrenching element of the fastener, which may be referred to as a wrenching element of the collar, is engaged with a tool, such as a socket of a ratcheting socket set, in order to turn the fastener into place. The ratcheting socket set tightens the fastener until an applied torque reaches the predetermined torque and the wrenching element breaks off the fastener, leaving the main body of the fastener, which may he referred to as a collar, secured to the bolt with the predetermined amount of torque.

A shortcoming of conventional methods for installing fasteners is that they do not provide a means to capture the portion of the fastener that breaks off (e.g., the wrenching element). For example, the wrenching element of the breakaway fastener may fall out of the socket when the ratcheting socket set is used, creating a foreign object debris (FOD) hazard if the wrenching element is not recovered. When installed on an aircraft, every wrenching element that breaks away from the fastener must be recovered or the wrenching element becomes FOD that may damage the aircraft. Thus, the conventional method of using a ratcheting socket set may increase the risk of FOD when using breakaway fasteners. Other conventional systems use a vacuum or catch basin to capture the wrenching element. However, these systems cannot work in tight corners or areas with limited space because they are bulky and generally unwieldy.

The improved system, method, and apparatus for installing and retaining a fastener described herein addresses these issues by interfacing with the ratchet and the socket. The apparatus, referred to as a fastener retainer tool, uses one or more arms with a lip to retain the wrenching element inside the socket. When the wrenching element is safe to dispose such that it will not create a FOD hazard, one or more arms of the fastener retainer tool may be actuated to release the wrenching element. The fastener retainer tool also allows the ratcheting socket set to be used to install the fastener with minimal differences compared to just using the ratchet and socket, thus the fastener retainer tool may beneficially be used with existing tools.

Example System for Installing and Retaining a Fastener

FIG. 1 depicts an isometric view of a system 100 for retaining a fastener, such as a breakaway fastener, according to an example of the present disclosure. In particular, FIG. 1 shows an apparatus 102 (referred to as a fastener retainer tool 102) for retaining a fastener installed with a ratchet 104 and a socket 106. As shown, the tool 102 is secured in between the ratchet 104 and the socket 106.

In the depicted embodiment, the tool 102 comprises a sidewall 110 configured to hold on to the socket 106. For example, the sidewall 110 surrounds an exterior portion of the socket 106. The socket 106 comprises an opening 108 configured to engage the breakaway fastener. For example, the fastener may be a breakaway fastener and the socket 106 may have a hex-shaped (e.g., hexagonal) opening 108 configured to engage a hex-shaped wrenching element of a collar of the breakaway fastener. The lip 112 of the tool 102 is configured to be pushed over a wrenching element of the collar as the wrenching element is pushed into the opening 108 of the socket 106. The ratchet 104 is configured to rotate the socket 106, which is configured to apply a torque to the fastener as the fastener is threaded onto a screw thread of a bolt, a screw, a threaded rod, a pin, or a similar element. In particular, the torque is applied to the wrenching element of the collar of the fastener and the wrenching element of the collar is configured to break away from the fastener and the collar at a predetermined torque. The lip 112 is further configured to retain the wrenching element of the fastener inside the opening of the socket 106, which beneficially prevents the wrenching element from falling out of the socket 106 and becoming foreign object debris (FOD).

In some embodiments, the tool 102 rotates with the socket 106 as the torque is applied to the fastener. In other embodiments, the sidewall 110 of the tool 102 has a loose fit with the socket 106, allowing the tool 102 to spin freely around a central axis (not shown) of the socket 106, which beneficially enables the tool to be reoriented with respect to the socket 106 or ratchet 104 during operation.

In some embodiments, the lip 112 is configured to hold on to the socket 106 in the tool 102 such that the socket 106 does not fall out of the tool 102.

Example Apparatus for Retaining a Fastener

FIG. 2 depicts an isometric view of the tool 102 for retaining a fastener, such as a wrenching element of a fastener, according to an example of the present disclosure. In the depicted embodiment, the tool 102 comprises a base 214, a plurality of arms 216, and a plurality of finger flanges 218.

The base 214 comprises a first aperture 220 having a central axis 222. A first end 216A of the arms 216 attaches to the base 214 and the arms 216 extend outward from the base 214. The arms 216 extend along the central axis 222. In some embodiments, the arms 216 may be offset by an angle from the central axis 222 when in an at-rest position, as shown in FIG. 2. For example, the arms 216 may be positioned at an angle of plus or minus 10 degrees from the central axis 222. The finger flanges 218 attach to the arms 216 and are configured to actuate the arms 216. For example, the finger flanges 218 may be configured to move the arms 216 in a direction away from the central axis 222 when the finger flanges 218 are actuated (e.g., moved towards the base 214). In some embodiments, the finger flanges 218 may be actuated by a user of the tool 102. In some embodiments, the user may use his or her fingers to pull the finger flanges 218 towards the base 214.

In this embodiment, arms 216 include biasing mechanisms 224 connecting the first ends 216A of the arms 216 to the base 214. The biasing mechanisms 224 are configured to relieve stress between the base 214 and the arms 216 when the arms 216 are actuated. For example, the biasing mechanisms 224 provide a flexible interface between the arms 216 and the base 214. In some embodiments, the biasing mechanisms 224 may be a spring. For example, the spring may be a compliant mechanism or an elastic element. In the depicted embodiment, the biasing mechanisms 224 have a curved shape that beneficially reduce a stress concentration factor, and thus reduces the maximum stress experienced by the tool 102, when the arm 216 is actuated, which leads to lower material fatigue and longer tool life. In this case, the curved shape of the biasing mechanisms 224 may be configured to increase an amount of cycles the arms 216 may be actuated during a lifetime of the tool 102. The curved shape of the biasing mechanisms 224 further functions as a spring to return the arms 216 to the at-rest position when the finger flanges 218 are no longer actuated. In some embodiments, the specific shape of the biasing mechanisms 224 may be different. For example, the biasing mechanisms 224 may have a different curvature or may be flat. In some embodiments, the biasing mechanisms 224 are continuous with a flat shape of the arms 216. For example, the arms 216 may have a flat shape extending from the base 214 to the lip 112. The biasing mechanisms 224 are a portion of the arms 216 that are configured to flex at or near the base 214 and provide the biasing function.

The base 214 further comprises the sidewall 110, which extends outward from the base 214 and surrounds the central axis 222 at some defined radius. In this embodiment, the sidewall 110 further includes stress relief notches 226. The stress relief notches 226 may comprise a curved shape that beneficially reduces the maximum stress experienced by the tool 102 when the arm 216 is actuated. The stress relief notches 226 may further be configured to increase an amount of actuation cycles the arms 216 are expected to endure during a lifetime of the tool 102.

The arms 216 comprises lips 112 at a second end 216B of the arms 216, which is at an opposite end of the arms 216 than the first end 216A. As previously discussed in relation to FIG. 1, the sidewall 110 is configured to hold on to a socket (e.g., the socket 106). The lip 112 is configured to retain the fastener or a wrenching element of the fastener inside the socket, such as a wrenching element of a breakaway fastener as discussed in relation to FIG. 1. The fastener may be partially installed prior to using the tool 102. For example, the collar of the breakaway fastener may be hand or finger tightened to a screw thread and the tool 102 may be used to finish installation of the fastener to a predetermined torque and retain the wrenching element after breakaway.

In some embodiments, lips 112 of the tool 102 comprises a draft angle or a taper (e.g., 228) and/or a second aperture 230. The second aperture 230 may be disposed on a side of the lip 112 nearest the central axis 222. The draft angle 228 and second aperture 230 of the lip 112 each may be configured to allow the lip 112 to be pushed over the fastener (e.g., a breakaway fastener) or wrenching element of the fastener, such as a wrenching element of a breakaway fastener, without needing to articulate the arms 216 using the finger flanges 218. For example, the draft angle 228 may be configured to allow the tool 102 to slide over the fastener by assisting the lip 112 of the arm 216 to be pushed over the fastener. The second aperture 230 may have a rounded shape configured to allow the lip 112 to be pushed over the fastener, such as the wrenching element of a breakaway fastener. Thus, the second aperture 230 allows the arm 216 of the tool 102 to move a lesser distance away from the central axis 222 when the tool 102 is pushed over a fastener, which may beneficially extend a fatigue life of and increases a number of times the tool 102 may be used.

The second aperture 230 may further grasp or hold on to the fastener after the lip 112 is pushed over the wrenching element of the fastener. For example, the second aperture 230 may allow the lip 112 to grasp the collar of the breakaway fastener once the wrenching element of the fastener is inside the socket, which beneficially may align the tool 102 to the fastener (e.g., the breakaway fastener) during installation. The lip 112 may grasp the collar at a location where the collar meets the wrenching element or at another location on a body of the collar. The finger flanges 218 may also be used to actuate the arms 216 of the tool 102 so that the lips 112 may be more easily pushed over the wrenching element of the collar.

As previously discussed in relation to FIG. 1, the wrenching element may break away when a predetermined torque is applied by another tool, such as a ratcheting socket set (shown in FIG. 1). The tool 102 is configured to retain the wrenching element inside the socket until a user is ready to safely dispose the wrenching element. The finger flanges 218 may be further configured to actuate the arms 216 to release the wrenching element from the socket by actuating the arms 112 as previously described. In some embodiments, the release of the wrenching element from the socket is directed into a foreign object debris (FOD) container or other target.

As previously discussed in relation to FIG. 1, the tool 102 may be mounted between a ratchet (e.g., the ratchet 104 in FIG. 1) and the socket. The first aperture 220 of the tool 102 may be configured to allow a drive (e.g. a socket connection interface) of the ratchet to penetrate the base 214 of the tool 102 and engage the socket.

In some embodiments, the apertures 220 and 230 allow additional tools, such as a hex key (e.g., an Allen key), to be inserted through the ratchet and the socket. For example, the hex key may be used to engage the screw thread and prevent the screw thread from rotating as the breakaway fastener is installed.

In some embodiments, the arms 216 further comprise a stiffener 232 attached to the biasing mechanism 224. The stiffener 232 may assist the biasing mechanism 224 by beneficially providing structural support to the arms 216.

In some embodiments, the finger flanges 218 actuate the biasing mechanisms 224 instead of the arms 216, and the biasing mechanisms 224 in turn actuate the arms 216. In some embodiments, each finger flange 218 comprises a flange cover (not shown). The flange covers may be configured to provide a grip to assist a user move the finger flanges 218 when actuating the arms 216. The flange covers may be made of a grip material, such as a rubber, foam, or cork. In some embodiments, the flange covers may further be used to identify the tool 102. For example, different color flange covers may be used for tools 102 configured to be used with different socket sizes. Different flange colors may also be used to identify what material the tool 102 is made of or whether the tool 102 is meant to be disposed of after use.

Generally, tool 102 may be made of a wide range of suitable, resilient, shape-keeping materials. In some embodiments, the tool 102 may be made of thermoplastics, such as nylon, polyethylene terephthalate glycol (PETG), or polylactic acid (PLA), which beneficially offer rigidity and flexibility. For example, the tool may be printed using a three-dimensional (3D) printer or formed using injection molding processes and the like. In some embodiments, fiber infused plastics may be used by a 3D printer to print the tool 102. Manufacturing the tool from a thermoplastic beneficially reduces the cost to manufacture the tool 102, and further allows the tool 102 to be a consumable item. Printing the tool 102 with a 3D printer beneficially allows the tool 102 to be manufactured on demand and customized before manufacture to fit any size of related tool, such as any size of socket and/or ratchet of a ratcheting socket set. For example, a dimension of the tool 102, such as a length of the arm 216, may be changed to accommodate sockets of different sizes. Thus, in some embodiments, the tool 102 may comprise different dimensions such that the tool may fit sockets and fasteners of different sizes.

In some embodiments, the tool 102 may be made of a metal, such as aluminum. For example, the tool 102 may be made out of a metal strip formed into shape, which beneficially allows the arms 216 of the tool 102 to have spring-like properties. In some embodiments, the tool 102 or portions of the tool may further be made of a magnetic material, which beneficially allows the tool to be picked up using a magnet and to further retain magnetic portions of fasteners, such as wrenching elements. For example, if the tool 102 becomes detached from the ratchet during use and falls in an area with limited space, a rod with a magnet may be used to pick up the tool 102.

In embodiments previously discussed, the tool 102 comprises several features that apply to each arm of the plurality of arms 216. In some embodiments, the tool 102 comprises one arm 216 and one finger flange 218. The arm 216 may further comprise other features previously described in relation to arms 216 such as the biasing mechanism 224, the lip 112, and the stiffener 232. The embodiment with one arm 216 may beneficially reduce the material required to manufacture the tool 102 and reduce the amount of moving parts of the tool 102.

FIG. 3 depicts a cross-sectional view of the tool 102 for retaining a fastener, according to the example embodiment from FIG. 2 of the present disclosure. In particular, FIG. 3 shows the elements of the tool 102 from a cross-sectional perspective.

In the depicted embodiment, tool 102 includes a generally solid material cross-section; however, in other embodiments, portions of the cross-sectional area may include porous or otherwise non-solid infill patterns, which may save material and weight without sacrificing significant strength, or may control an amount of flexibility (e.g., biasing) of the tool 102.
