Abstract:
Elastomeric joining element retaining devices are disclosed. In an aspect, a retaining device is disclosed which is constructed from an elastomeric material such as polyurethane and designed to receive and align an assembly or “stack-up” of nuts, bolts, washers, and/or other joining elements. The retaining device retains and aligns the assembly, enabling a user to install the assembly accurately without dropping or misaligning portions of the assembly. Such retaining devices ease the process of installing or removing joining elements in hard to reach locations.

Description:
FIELD OF THE DISCLOSURE 
     The present disclosure relates to hand tools and more particularly to equipment for manipulating fasteners and fastener assemblies. 
     BACKGROUND 
     Installing, locating or removing fasteners, washers, spacers, clips, assembly components or similar devices is often difficult, especially in hard to reach or orientate places. There are numerous standard threaded fasteners such as bolts, nuts and complimentary components, such as washers, used to assemble, locate and attach all kinds of parts on machines, household furnishings, buildings and the like. There are numerous other specialty fasteners, components and sub-assemblies that must be inserted in a particular order and position. Due to the virtually infinite mating orientations of components that must be fastened or inserted together it is often necessary to install a fastener or an assembly of fastener components in difficult to access or blind locations. Installing a fastener or an assembly of fastener components may be assisted by applying a sticky material (e.g., gum, spittle, double-sided tape, resin, and the like) between the backside of a fastener and a user&#39;s finger in an attempt to temporarily overcome gravity and carefully guide the fastener into position. This requires a significant amount of patience and balance and is not suitable for all installation locations. In blind situations the “feel” of the fastener making proper engagement is often required, confirming proper engagement. Further, this process is difficult when installing an assembly of fastener components because only the fastener itself is retained by the sticky material. Components often become misaligned, resulting in cross threading or the components falling and becoming lost or ending up in difficult to retrieve locations. In some cases, the loss of a fastener can be catastrophic such as when the fastener falls into a machine and latter becomes lodged in moving components. 
     In addition to the methods previously described, there are many specialized tools and accessories for installing fasteners in these situations. Such devices include special mechanical or magnetic gripping features. The tools themselves often interfere with easy alignment of the fastener and the mating thread or component feature thus making final assembly/disassembly difficult. 
     Magnetized sockets are known which provide some retaining force for ferromagnetic nuts, bolts and other fasteners. Magnetic inserts, such as the inserts disclosed in U.S. Pat. No. 5,146,814 issued on Sep. 15, 1992 to Richard Vasichek (the &#39;814 Patent), are known which may be placed inside non-magnetic sockets and provide a magnetic retaining force. These devices are not suitable for aluminum components, plastic components, and other non-ferromagnetic components. 
     U.S. Pat. No. 5,323,673 issued on Jun. 28, 1994 to Florence Martinez et al. (the &#39;673 Patent) discloses a nut or bolt holder socket having a leg, beam, cam, or other mechanism positioned within the socket cavity for retaining a nut within the socket, thereby aiding the use in installing the nut in a hard to reach place. 
     U.S. Pat. No. 5,896,792 issued on Apr. 27, 1999 to Jon Hurt (the &#39;792 Patent) discloses a thin, flexible plastic holder designed to retain a bolt in a socket by reducing the tolerance between the bolt head and the socket, creating a friction fit which holds the bolt within the socket. An enlarged head of the holder is placed between the bolt head and the socket and deformed therebetween as the bolt head is forced into the interior of the socket. A second enlarged head of the holder is deformed between the drive socket and a wrench drive fitting or extension in order to retain the holder. 
     U.S. Pat. No. 6,302,000 issued on Oct. 16, 2001 to James Smith (the &#39;000 Patent) discloses a device for positioning nuts in cramped spaces. The &#39;000 Patent device is a wire having a handle at a first end and a bend second end. The bent second end is arranged such that a nut may be placed within the bent section, held there and placed on a target bolt. The &#39;000 Patent device does not provide any lateral support for the nut. The bent section merely loops around a portion of the perimeter of the nut. 
     U.S. Pat. No. 7,246,540 issued on Jul. 24, 2007 to Robert Rillera (the &#39;540 Patent) discloses a fastener retaining device capable or retaining multiple nuts, bolts, and washers and starting installation of such joining elements via three extendable gripping prongs. The inside surfaces of the prongs contact and retain the joining elements and a desired torque may be applied via an attached handle. A lever on the handle allows the user to extend or retract the gripping prongs, causing the device to release or engage a joining element. 
     Given the foregoing, what is needed are devices which retain nuts, bolts, washers and assemblies thereof during installation, particularly in hard to reach places or in locations where it is difficult to maintain the alignment of such assemblies and experience the “feel” of proper engagement during installation. In particular, devices are needed which can, without magnets, retain and facilitate the installation of nuts, bolts, washers, spacers, other joining elements and assemblies thereof. Low profile devices and/or devices capable of providing support in more than one direction are also needed. 
     SUMMARY 
     This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. It is not intended to identify key features or essential features of the subject matter to be claimed, nor is it intended to be used to limit the scope of the subject matter to be claimed. 
     For the purposes of the present disclosure, the term “joining element” and/or the plural for of this term may be used throughout herein to refer to objects which singly or in conjunction with other objects are used to mechanically join or affix two or more objects together. Joining elements include, but are not limited to, nuts, bolts, screws, washers, spacers, retaining rings, and the like. 
     The present disclosure is directed to devices which retain one or more joining elements and assemblies thereof during installation, storage or removal. Such devices help reduce the risk of dropping joining elements during installation or removal which, as disclosed above, may slow operations or damage equipment. 
     In some aspects, devices in accordance with the present disclosure facilitate installation or removal of joining elements from tight spaces, hard to reach places and blind installation locations. Aspects of the present disclosure ensure that joining element assemblies remain aligned during installation, avoiding cross threading and other installation failures. 
     In an aspect, an elastomeric joining element retaining device is disclosed. The device is constructed of an elastomeric material such as neoprene rubber or polyurethane. The device includes a cavity designed to receive and align an assembly or “stack-up” of multiple joining elements along a central attachment axis. Each of the joining elements may be retained within the cavity at a location having a perimeter equal to the outer walls of the joining element. The elastomeric material retains each joining element via a friction fit applied to the outer walls of the joining element. In some aspects, the cavity walls stretch slightly when the joining elements are inserted and the tension in the elastomeric material facilitates retaining and aligning the joining elements. In other aspects, the cavity is configured to receive a single joining element, such as a single wing nut, hex head bolt, or the like. 
     In some aspects, devices in accordance with the present disclosure are constructed from elastomeric materials having a hardness of approximately 80 Shore A. 
     Aspects of the present disclosure facilitate installation, removal, and/or starting of joining elements and assemblies of joining elements without using magnets (which are unsuitable for plastics and non-ferromagnetic materials) or gripping prongs (which may damage objects, bend or break with usage) and provide support for the joining elements in more than one direction. 
     In an aspect, an elastomeric joining element retaining device is provided which is constructed of a disposable material. The retaining device may be provided to a user (e.g., a consumer as part of a kit) containing an assembly of joining elements (e.g., a bolt having two washers positioned on the bolt shank), enabling the user to install the assembly of joining elements contained therein using the retaining device and discard or save the retaining device for subsequent reuse. 
     In aspects of the present disclosure, retaining devices are provided which have exterior surface features which help users grip the retaining device as it is turned.

     DETAILED DESCRIPTION 
     The present disclosure is directed to elastomeric joining element retaining devices which retain one or more joining elements and assemblies thereof during installation or removal. Such devices facilitate installation, removal, storage and/or manipulation of joining elements. Further, such devices help reduce the risk of dropping joining elements during installation or removal which may slow operations or damage equipment. 
     For the purposes of the present disclosure, the term “joining element” and/or the plural for of this term may be used throughout herein to refer to objects which singly or in conjunction with other objects are used to mechanically join or affix two or more objects together. Joining elements include, but are not limited to, nuts, bolts, screws, washers, spacers, clips, posts, pins, studs, retaining rings, and the like. 
     Referring now to  FIGS. 1-4 , various views of an elastomeric joining element retaining device  100 , including a top perspective view, a cutaway view, a view of various joining elements of an assembly which may be retained within the retaining device  100 , and an assembly loaded into retaining device  100 , in accordance with aspects of the present disclosure, are shown. 
     In various aspects, retaining device  100  may be constructed of rubber, synthetic rubber, neoprene rubber, polyurethane, a synthetic pliable material, recyclable plastic, natural fibers, or any other materials having appropriate flexibility and durability requirements identified by a person skilled in the relevant art(s) after reading the description herein. In various aspects, retaining device  100  may be constructed of, for example, an oil resistant elastomer having a hardness of approximately 80 Shore A. Retaining device  100  may be constructed of multiple materials, including materials of various hardnesses. For example the material surrounding cavities  202 ,  204 ,  206  may be 80 Shore A rubber. The rubber may be bonded to material around cavity  208  which comprised of a harder material such as plastic or metal, or a softer material such as 60 Shore A rubber. Retaining device  100  may contain specialized reinforcements or fibers such as anti-static materials for use with sensitive electronic components or Kevlar fibers for added strength to reduce the overall diameter but still maintain sufficient mechanical properties for the intended use. 
     In some aspects, device  100  is constructed with an overall buoyancy that allows device  100  to float in water. Device  100  may be constructed of foamed urethane, rubber or a similar material. The overall buoyancy may take into account the mass of joining elements device  100  is designed to carry, thereby allowing device  100  and inserted joining elements to avoid being lost by floating if dropped in water. 
     Retaining device  100  includes a retaining device body  102  having an outer surface  106 , a first end portion and a second end portion. One or more cavities  104  are present within retaining device body  102 . Cavity  104  is a recess configured to receive one or more joining elements. In some aspects, retaining device  100  is provided with joining elements or an assembly of joining elements already deposited within cavity  104  for quick deployment, storage, and the like. 
     Installing, removing, or otherwise manipulating joining elements via cavity  104  facilitates installation, removal, and/or starting of joining elements and assemblies of joining elements without using magnets (which are unsuitable for plastics and non-ferromagnetic materials), gripping prongs (which may damage objects are difficult to orient and maintain relative positions of joining elements, remove the “feel” of correct alignment and engagement) and provide support for the joining elements in more than one direction because cavity  104  may envelope multiple sides of the joining element or assembly of joining elements. 
     In some aspects, device  100  is molded from an elastomer and body  104  is configured to receive one or more standard SAE half-inch fasteners. Body  104  may have dimensions of approximately 1¾ inches in diameter and 1½ inches tall. 
     In some aspects, body  102 , or all of device  100  may be constructed of a disposable material or a material which degrades or breaks down after a single use or a few uses. Such single use or disposable or recyclable retaining devices  100  may be created from low-cost materials and be useful for installing joining elements and/or assemblies in furniture kits and the like, rather than, or in addition to tools supplied within the kit or user-supplied tools. Retaining device  100  may be provided to a user (e.g., a consumer as part of a kit) containing an assembly of joining elements (e.g., a bolt having two washers positioned on the bolt shank), enabling the user to install the assembly of joining elements contained therein using retaining device  100  and discard or save the retaining device for subsequent reuse. Joining elements may by pre-packaged in retaining device  100 , reducing packaging count and assembly errors. 
     As shown in  FIG. 2 , cavity  104  of retaining device  100  may include multiple sub-cavities having different geometries. Each sub-cavity may be configured to accommodate a specific joining element, joining elements having similar dimensions, or multiple joining elements which make up part of the overall assembly of joining elements retained by retaining device  100 . Sub-cavities may have circular cross sections, hexagonal cross sections, or other geometries apparent to those skilled in the relevant art(s) after reading the description herein. Each sub-cavity is open to the sub-cavity preceding it and may include a rear wall portion. In some aspects, a central area of each sub-cavity remains open, thereby allowing the shank of a bolt, screw, or similar fastener to pass through each sub-cavity and the joining element contained therein. In this fashion, an assembly of joining element containing a bolt, screw, or similar extended fastener may be aligned. Sub-cavities may have larger or smaller cross sections than adjoining sub-cavities. Sub-cavities may be sized to retain joining elements via compression. Sub-cavity features may extend through the entire body  102 , facilitating the removal of elements that are inserted in error or with an incorrect orientation. The compression may create a friction fit for joining elements held within retaining device  100 . Such retention enables joining elements to be retained in retaining device  100  as retaining device  100  is maneuvered into position to install the joining elements in, for example, a tight space, a hard to reach place, a blind installation location, a location requiring turning retaining device  100  upside down, and the like. 
     In an aspect, each sub-cavity is sized 2-2.5% smaller than the lower bound of the tolerance of the joining element intended to be retained by the sub-cavity. For example, for a sub-cavity having a circular cross section and configured to retain an ANSI/ASME B18 22.1-1965(R1998) ½-inch Type B Regular Plain Flat washer, the sub-cavity may have a diameter of 1.090 inches because the lower bound of tolerance of the outer diameter of such a washer is 1.118 inches. Sizing each sub-cavity smaller than the intended joining element facilitates retaining the joining element via compression. 
     In some aspects, cavity  104  and/or sub-cavities may be sized for Imperial sized-fasteners (e.g., a half-inch hex bolt), but the elastomeric nature of the construction of retaining device  100  facilitates retaining ISO standard fastener sizes (e.g., 13 or 14 mm hex bolts). 
     Body  104  may further include a drive socket  208  for interfacing with, for example, a ratchet wrench. In some aspects, drive socket  208  is an open square chamber sized to connect with a ⅜ inch ratchet drive. In other aspects, drive socket  208  is open on only one side. 
       FIG. 2  depicts retaining device  100  operable with standard SAE half-inch fasteners. Retaining device  100  may include cavity  104  comprising three sub-cavities: a flat washer cavity  202 , a split-lock washer cavity  204 , and a hexagonal joining element cavity  206 . Flat washer cavity  202  is a circular recess for a type 2 flat washer. Washer cavity  204  is a circular recess for a split-lock washer. Hexagonal cavity  206  is a recess having a hexagonal cross section suitable for receiving a half-inch hex head bolt, hex nut, or the like. 
     An assembly  308  of joining elements may be retained. Assembly  308  may comprise a flat washer  302 , a split ring washer  304 , and a hex head bolt  306 . Assembly  308  may be retained by retaining device  100  by first inserting bolt  306  into cavity  206 , then inserting split ring washer  304  into cavity  204  and around the shank of bolt  306  and finally inserting flat washer  302  into cavity  202  and around shank of bolt  306 . When placed within retaining device  100 , the shank of bolt  306  may protrude from retaining device  100 , enabling shank to be inserted into a thread hole or the like and installed. 
     Referring now to  FIGS. 5 &amp; 6 , a top perspective view and a cutaway view of elastomeric joining element retaining device  100  configured to retain assembly  308  comprising washer  302 , split ring washer  304  and a hex nut  502 , in accordance with an aspect of the present disclosure, are shown. 
     Retaining device  100  may retain female joining elements and be utilized to install or remove assembly  308  of female joining elements at a desired location. For example, retaining device  100  may retain hex nut  502 , split ring washer  304  and flat washer  302 . Via retaining device assembly  308  may be screwed onto a bolt. Afterward, retaining device  100  may be removed. 
     Referring now to  FIGS. 7 &amp; 8 , a top perspective view and a cutaway view of elastomeric joining element retaining device  100 , in accordance with an aspect of the present disclosure, are shown. 
     In some aspects, cavity  104  comprises only sub-cavities having circular cross sections. Due to the elastic nature of the construction of body  102 , the circular sub-cavities may accommodate circular joining elements (e.g., flat washers, lock washers, and the like), square joining elements, hexagonal joining elements, joining elements having irregular geometries and the like. As shown in  FIG. 8 , washer sub-cavity  202  and split ring washer sub-cavity  204  may be arranged over a third sub-cavity  206  having a circular cross-section which may still stretch and retain a hex head bolt or the like. 
     Outer surface  106  of retaining device  100  may be configured in a variety of ways in order to, for example, assist the user in turning retaining device  100  by hand or insert or remove joining elements. Outer surface  106  may also be configured to facilitate connecting retaining device  100  to driving tools such as a square driver, a ratchet wrench, or the like. 
     Referring now to  FIG. 9 , a top perspective view of elastomeric joining element retaining device  100  having a partially knurled outer surface  106 , in accordance with an aspect of the present disclosure, is shown. A portion of outer surface  106  may comprise ridges, bumps, knurls  902  or the like in order to make it easier to grip retaining device  100 . 
     Referring now to  FIG. 10 , a top perspective view of elastomeric joining element retaining device  100  having flutes  1002  for (labeled, for clarity, only as flute  1002   a  in  FIG. 10 ) gripping by a user, in accordance with an aspect of the present disclosure, is shown. Outer surface  106  may include one or more flutes  1002  which protrude from body  102  and help the user grip and twist retaining device  100 . 
     Referring now to  FIG. 11 , a top perspective view of elastomeric joining element retaining device  100  having an opening  1102  along a portion of the retaining device length and a retaining ring  1104 , in accordance with an aspect of the present disclosure, is shown. 
     Opening  1102  operates as an expansion slit in retaining device  100 , expanding and exposing cavity  104 . In some aspects, opening cavity  104  in this manner allows the insertion of irregular or out or tolerance joining elements. Once inserted, the joining element or elements may be installed via normal operation of retaining device  100 . The joining element may be inserted by first removing retaining ring  1104 , enabling manual spreading of opening  1102 . Opening  1102  may be spread open and the desired joining elements inserted into cavity  104 . Opening  1102  may then be released and retaining ring  1104  reseated in order to hold joining elements within cavity  104  by compression. Examples of irregular joining elements which may be operated with the assistance of retaining device  100  include but are not limited to welded up T-bolts. Retaining ring  1104  may be a split metal ring, a flexible o-ring, or the like. Body  102  may include a groove which receives retaining ring  1104 . 
     In some aspects, body  102  or retaining ring  1104  is designed to release, split, give way, or otherwise stop transferring torque to joining elements contained therein as they are being installed. For example, body  102  may be constructed of a material having a hardness which will cause hex-head fasteners to slip within cavity  104  and no longer be tightened once the fastener torque has reached 32 ft-lbs. Retaining ring  1104  may be an elastomeric member, a spring, a split ring or similar device configured to give way when a torque of greater than 32 ft-lbs is applied. As will be apparent to those skilled in the relevant art(s) after reading the description herein, retaining device  100  ability to apply joining elements or joining element assemblies and release such elements or assemblies at a desired torque may be useful for assembly of delicate components such as circuit boards. Retaining device  100  may be configured to release joining elements, spin, or otherwise stop applying a torque when torque in the in-lbs range have been applies. 
     Referring briefly now to  FIG. 12 , a top perspective view of elastomeric joining element retaining device  100  having a hexagonal outer profile  106 , in accordance with an aspect of the present disclosure, is shown. In some aspects, outer profile  106  is chosen to conform with standard socket profiles, or to have a hex profile thereby enabling manipulation by tools such as a wrench. 
     Referring now to  FIG. 13 , a top perspective view of elastomeric joining element retaining device  100  having two or more cavities (labeled as cavities  104   a - c  in  FIG. 13 ) for retaining joining elements, in accordance with an aspect of the present disclosure, is shown. 
     Retaining device  100  may include multiple cavities  104  having different sub-cavity profiles, different numbers of sub-cavities, different widths, different depths, and the like. In this manner, a single retaining device  100  may be used for multiple assemblies  308 , joining devices which have different sizes and/or profiles, and the like. 
     Retaining devices  100  having multiple cavities  104  may be used in assembly line processes. Such retaining devices  100  may be preloaded with the necessary assemblies  308 , enabling workers to pick up a single retaining device  100  and install multiple assemblies  308  of joining devices or multiple joining devices, thereby reducing time of installation and increasing alignment accuracy for each assembly  308 . In some aspects, retaining device  100  can be designed so at least one fastener or joining element extends beyond the edge of device  100  so that the exposed fastener length and/or the outer shape of the retaining device  100  will only engaged in a select receiving cavity, thereby reducing assembly errors. 
     Referring now to  FIG. 14 , a top perspective view of elastomeric joining element retaining device  100  configured for a wing nut  1402 , in accordance with an aspect of the present disclosure, is shown. Cavity  100  or a sub-cavity may have a cross section similar to wing nut  1402 , thereby allowing retaining device to be used with wing nut  1402 . Cavity  100  or a sub-cavity may have a cross section suitable for receiving other specialty joining elements including but not limited to panel fasteners, hooks, hook eyes, captive fasteners, square head fasteners, pan head screws, slotted head screws, phillips head screws, security head screws and bolts, carriage bolts, U-type fasteners and the like. 
     Referring now to  FIG. 15 , a top perspective view of a set  1500  of elastomeric joining element retaining devices  100 , in accordance with an aspect of the present disclosure, is shown. 
     In some aspects, retaining devices  100  may be created in sets  1500 . Set  1500  may be modeled after common socket sets. For example, a common set could be for ¾, 11/16, ⅝, 9/16, ½, 5/16, and ⅜-inch sizes. In some aspects, due to the elastomeric construction of retaining devices  100 , set  1500  may be used for both Imperial-sized joining devices and metric-sized joining devices. For example, 12 mm is very close to ½ inch but slightly smaller (½ inch=12.7 mm) than 12 mm. The elasticity of retaining device  100  will accommodate this disparity in dimensions. 
     Referring now to  FIGS. 16-18 , various views of elastomeric joining element retaining device  100  having at least one lip and multiple bosses for retaining joining elements, including a top perspective view, a cutaway view, and view featuring an assembly loaded into retaining device  100 , in accordance with aspects of the present disclosure, are shown. 
     Retaining device  100  may further include one or more physical stops, such as bosses  1602  (labeled as bosses  1602   a - d  in  FIG. 16 ), at least one lip  1604 , and/or other protrusions into cavity  104  designed to improve retention of a joining element seated therein. Such bosses  1602 , lips  1604  or other protrusions may be placed at an upper or lower boundary of a sub-cavity, such as flat washer cavity  202  or split-lock washer cavity  204 . In other aspects, such bosses  1602 , lips  1604  or other protrusions may be located on the walls of cavity  104  at points contacting the middle, upper side, or lower side of the joining element contained therein. 
     In some aspects, joining elements, including for example, precision fasteners, may become slightly cocked or otherwise angled within retaining device  100 . This may occur where cavity  104  is slightly larger than the maximum tolerance dimensions of joining element being retained. Bosses  1602 , lips  1604  or other physical stops assist in retaining such joining elements in their respective sub-cavities. In some aspects, the physical stop (e.g., boss  1602 , lip  1604 ) extends into cavity a sufficiently short distance that it may deform to allow loading of the joining element. Cavity  104  or sub-cavity may be made slightly deeper to allow the inserted joining element to “float” or self-align. 
     Referring now to  FIGS. 19-20 , various views of elastomeric joining element retaining device  100  having a rigid driving insert  2002 , according to various aspects of the present disclosure, are shown. 
     Retaining device  100  may include rigid insert  2002 . Rigid insert  2002  may be configured to retain one or more joining elements, transfer applied torques to the joining element(s) contained within retaining device  100 , and the like. For example, a wood screw  1902  having a Phillips head may inserted into cavity  104 , stabilized by bosses  1602  and connect for stabilization and/or to receive torque with rigid driving insert  2002  at a drive tip  2004 . Drive tip  2004  may be any configuration apparent to those skilled in the relevant art(s) after reading the description herein, including hex, hex socket, Phillips, slot, square, and the like. Driving insert  2002  may be integral with retaining device  100  or it may be removable. Driving insert  2002  may be positioned along a central attachment axis of retaining device  100 . 
     While various aspects of the present disclosure have been described above, it should be understood that they have been presented by way of example and not limitation. It will be apparent to persons skilled in the relevant art(s) that various changes in form and detail can be made without departing from the spirit and scope of the present disclosure.
