RELATED APPLICATIONS  
       [0001]    This application claims the benefit of Provisional Patent Application Serial No. 60/395,243, filed 11 Jul. 2002, which claims the benefit of Provisional Patent Application Serial No. 60/382,436, filed 22 May 2002. 
     
    
     
       BACKGROUND OF THE INVENTION  
         [0002]    This invention generally relates to specialized mounts for use with cable ties in securing elongate items, such as wires, cables, hoses, tubing, or conduits to an adjacent metallic structural member. More particularly, the invention relates to a mount that can be secured to a base metal by stud welding the mount to the metallic structural member.  
           [0003]    Molded plastic cable ties are known in the art and are used to secure wires, cables, hoses, tubing, or other elongate articles in tight bundles.  
           [0004]    Presently, mounting supports used in conjunction with cable ties or other strap-like bundling means are limited to configurations in which the mount and attached items are secured to a structural support member by way of communicating apertures through the structural member and mount. This arrangement typically requires drilling and tapping through the structural member to create the attachment aperture. This attachment means is sufficient in applications using readily borable support material, but is not practical when an aperture is not easily made in a predetermined support structure, such as when the reverse side of the support structure is not accessible. Further, the support material may be of an unworkable thickness. Also to be considered is the process of drilling and possibly tapping an aperture in the support member, which may be undesirably slow and labor intensive, adding to the overall cost of the end product. It may also be undesirable to create an aperture in a support member, such as in instances in which leakage or corrosion through the aperture is possible.  
           [0005]    The present invention provides a mounting assembly that is stud welded directly onto the support surface of a metallic support member without the need for an aperture through the support member itself.  
           [0006]    Stud welding is a high-speed joining process in which a stud or other metal part is affixed to a metal support structure. Metals that may be stud welded include steel, stainless steel and aluminum, among others. A weld gun loaded with a stud places the stud in contact with the metallic support structure. When the weld gun is activated, the gun tip initiates an electrical arc to melt the stud base and the contacted area of the metal support structure. The stud is then forced into the melted area in the support structure and is held in place until the metal solidifies and the bond is formed. In most instances, a stud weld is stronger than the stud itself and is compatible with most weldable materials, including dissimilar materials. The stud welding process allows welding to thin and sheet metal grade support material with no reverse side marking, as well as providing structural-type strength in welding to heavier support materials. Since the entire process is accomplished in milliseconds, bonds formed in this way lend themselves to high volume production and automated processes. Further, stud welding eliminates drilling and tapping of apertures through the support structure, provides optimal bond strength, avoids reverse side marking, and saves time and cost.  
         SUMMARY OF THE INVENTION  
         [0007]    The present invention provides a mounting assembly for use in securing bundled articles to a metal support structure using a stud welding technique. The assembly includes a mount element and, optionally, an elongated cable tie having a strap portion for circumscribing bundled articles. The mount element includes at least one opening therethrough, a base surface, and one or more support surfaces.

     DETAILED DESCRIPTION  
       [0054]    Although the disclosure hereof is detailed and exact to enable those skilled in the art to practice the invention, the physical embodiments herein disclosed merely exemplify the invention which may be embodied in other specific structure. While the preferred embodiment has been described, the details may be changed without departing from the invention, which is defined by the claims.  
         [0055]    Like features and structural elements are referred to by like reference characters.  
         [0056]    Referring to the drawings, and in particular to FIGS.  1 - 5 , inclusive, a mounting assembly  10  embodying the various features of the invention is shown. The assembly  10  functions to secure elongate items, such as wires, cables and the like into bundles  8  (shown in phantom) and to secure the bundles  8  to an adjacent metallic structural member  12 . It will be apparent that the “bundle”  8  may comprise multiple wires, conduits, or cables that are flexible or rigid, hot or cold, or fluid transporting hoses or tubes. Some elongate items may also be contained within the bore of a conventional tubular conduit. The assembly  10  is particularly well suited for use in applications requiring fastening to a metallic structural member  12 . The present invention is especially useful in situations characterized by limited access to the reverse side  11   a  of the structural member  12  or in instances when it is not feasible to mount to the support surface  11   b  of the structural member  12  by way of a conventional nut and bolt arrangement.  
         [0057]    As illustrated in the view of FIG. 1, the assembly  10  includes two principal components, namely an integrally formed mount member  14  and a cable tie  16  having an elongate strap portion  18  molded with a plurality of serrations  19  conventionally engagable with a locking pawl (not shown) located integrally of the cable tie head  17 . With reference to FIGS.  2 - 5 , inclusive, the mount member  14  with stud weld fastener  22  is seen in detail.  
         [0058]    The mount member  14  is shown without the stud weld fastener  22  in FIG. 1 a . The mount member has an angularly extending arm  40  (see FIG. 1) with stud aperture  20  that receives the stud weld fastener  22  (see FIG. 1). An arched surface support  26  has a tie aperture  24  for receiving the cable tie  16 . The arched surface support  26  is shown with an H-shaped arrangement. While not necessary for the invention, such an arrangement provides added support for the bundle  8  while minimizing the area that the cable tie  16  must maneuver to engage the mount member  14 . Further, the arched surface of the support  26  fits the shape of the bundle  8  and contributes to securely hold the bundle  8  in place. The base  26   a  of the support surface  26  is shown as a solid section for added support, but may also be minimized or removed to allow more access for the bundle strap tie  16 . Also, a notch  26   b  may be integral with the base  26   a  to allow sufficient room for the stud weld fastener  22  to be placed in the stud aperture without interfering with the support surface  26 . Once again, this is not necessary for the invention and will not be necessary if the base  26   a  is not utilized in a specific embodiment of the invention.  
         [0059]    The mount member  14  comprises the arched support surface  26 , and the angularly extending arm  40 . The arm  40  further includes an underside base surface  28  with stud aperture  20  (see FIG. 5) extending therethrough. The aperture  20  is arranged to receive a stud weld fastener  22 . The arched support surface  26  is arranged for supporting engagement of a bundle  8 , as shown in phantom in FIG. 1, while the underside base surface  28  mates with the support surface  11   b  of the metallic structural member  12  (see FIG. 1). The arched support surface  26  is relatively wide and creates broad surface contact with the bundle  8  to minimize pinching and crushing of the bundle  8  or its components. The mount member  14  is further provided with the tie aperture  24  (see FIGS. 4 and 5) for receiving and guiding the conventional cable tie  16 . As best seen in FIG. 5, the tie aperture  24  is provided with a relatively distended end  42  and a constricted end  44 . The constricted end  42  provides a convenient entrance for feeding the end of the strap portion  18  of the cable tie  16  into the aperture  24 . The distended end  42  opens toward the base surface  28 , while the constricted end  44  terminates at the opposite surface. As further seen in FIG. 5, the tie aperture  24  includes an inwardly tapered wall surface  46  and an inner wall surface  48 . The inner wall surface  48  extends substantially parallel to the axis of the stud weld fastener  22  and stud aperture  20 . The exterior surface of the tapered wall surface  46  corresponds to the arched support surface  26 . The tie aperture  24  provides a throughway for receiving the cable tie  16  used to securely engage the bundle  8  to arched support surface  26  (see FIG. 1).  
         [0060]    As is best seen in FIGS. 4 and 5, the mount member  14  includes a stud aperture  20  for receiving a stud weld fastener  22 , and a tie aperture  24  for receiving the strap  18  of cable tie  16 . As seen particularly in FIG. 5, the stud weld fastener  22 , arranged to extend through the aperture  20 , preferably includes a supporting extension  22   a , base  22   b  and a radially extending ferrule  22   c  engagable with the upper surface  40   a  of arm portion  40  of the mount member  14 .  
         [0061]    The mount member  14  can be fabricated from any non-metallic material. The preferred material is nylon 6/6. Alternatively, any suitable plastic material could also be used.  
         [0062]    Installation of the assembly  10 , illustrated in FIGS.  1 - 5 , may be seen in the views of FIGS. 6 a - 6   c . The mount member  14  is molded with the stud weld fastener  22  extending through the stud aperture  20 . The fastener  22  includes a supporting extension  22   a  and a base  22   b . The extension  22   a  is arranged for insertion into the bore of a stud welding gun  38  (shown in phantom) during the stud welding procedure. The stud welding gun  38  with attached extension  22   a  and mount member  14  presses the stud fastener base  22   b  against the support surface lib of the structural member  12  to be mounted. Upon activation of the stud welding gun  38 , an electrical arc between the fastener  22  and the structural member  12  fuses the base  22   b  of the stud fastener  22  and the contacted area in the structural member  12 . As shown in FIG. 6 b , the stud fastener  22  and attached mount member  14  is pushed into the fused area until the metal solidifies and a bond is formed. The extension  22   a  may be removed by conventional means such as sawing and/or grinding, or the like. As shown in FIG. 6 c , a cable tie  16  strap  18  is then passed through the tie aperture  24  for circumscribing a bundle  8  to be placed in position for support.  
         [0063]    Referring now to FIGS.  7 - 9   a , an alternative embodiment mounting assembly  10   a  may be seen. As seen particularly in FIG. 8, the mount member  14   a  may include an arm  40  having an upper surface  40   a  including a countersunk portion  34 . Countersunk portion  34  may be adapted to receive the radially extending ferrule  22   c  of stud fastener  22 . As shown in these views, the countersunk ferrule  22   c  allows the upper surface  40   a  of arm  40  to remain relatively smooth. FIG. 9 a  illustrates an alternative stud weld fastener  22  having a base portion  22   b  with a modified, sharply pointed end  50 . The pointed end  50  may be desired, when, for example, the metallic structural member  12  is painted, and it is necessary to pierce the treated surface immediately prior to welding.  
         [0064]    As illustrated in FIGS.  10 - 12   a , inclusive, another alternative embodiment mounting assembly  10   a  is seen. As seen, the mount member  14   a  may include an arm  40  having countersunk portions  34   a ,  34   b  in both the upper surface  40   a  and the base surface  28 , respectively. Further, the assembly  10   a  includes a stud weld fastener  22  having two, radially extending, axially spaced, ferrules  22   c . The spaced-apart ferrules  22   c  are each respectively received in the countersunk portions  34   a ,  34   b . This configuration may be desired for added strength. FIG. 12 a  shows the embodiment of FIGS.  10 - 12  with modified base  22   b  having a pointed end  50 .  
         [0065]    FIGS.  13 - 15   a , inclusive, illustrate yet another alternative embodiment mounting assembly  10   a . As will be observed particularly in FIG. 14, the mount member  14   a  may include a stud aperture  20  having an irregular, generally undulating, inner surface  36 . Further, the assembly includes a stud weld fastener  22  having an irregular portion  22   d  located intermediate the extension  22   a  and the base  22   b . The irregular portion  22   d  is configured for mating engagement of the generally undulating, irregular inner surface  36  of stud aperture  20 . FIG. 15 a  shows the embodiment of FIGS.  13 - 15  with modified base  22   b  having the pointed end  50 .  
         [0066]    As revealed in FIGS.  16 - 18   a , inclusive, still another alternative embodiment mounting assembly  10   a  is illustrated. As illustrated, particularly in FIG. 17, the mount member  14   a  may include a stud aperture  20  having an annular cavity  52 . Further, the assembly includes a stud weld fastener  22  having a radially extending ferrule  22   c  located intermediate the extension  22   a  and the base  22   b . The radially extending ferrule  22   c  is adapted to be received in the annular cavity  52  in stud aperture  20 . FIG. 18 a  shows the embodiment of FIGS.  16 - 18  with modified base  22   b  having pointed end  50 .  
         [0067]    An alternative embodiment mounting assembly lob may be seen in FIGS.  19 - 21 , inclusive. In this embodiment, the mount member  14   b  and strap  18  are integrally formed. As in the embodiments shown in FIGS.  1 - 18   b , the mount member  14   b  of this alternative embodiment includes a tie aperture  24   a  and a stud aperture  20  for receiving a stud weld fastener  22  having a projecting extension  22   a . In this embodiment, as well as in the embodiment of FIGS.  1 - 18   c , the extension  22   a  may be removed by conventional sawing and/or grinding techniques after being welded to the structural member  12 . The stud aperture  20  of alternative assembly  10   b  is preferably of a diameter to allow interference fit for an inserted stud weld fastener  22 . The integrally formed strap portion  18  preferably includes serrations  19  which extend transversely across the strap  18 . The serrations  19  are dimensioned to interlock with a corresponding pawl (not shown) in the tie aperture  24   a . It is to be noted that alternative embodiment assembly  10   b  may be used to support bundle  8  against a structural member  12  having an edge  13 .  
         [0068]    Another alternative embodiment mounting assembly  10   c  may be seen in FIGS.  22 - 25 , inclusive. As illustrated in these views, the assembly  10   c  includes an integrally formed mount member  14   c  having a stud aperture  20  for receiving a stud weld fastener  22  and at least one arcuate bundle support surface  54  adapted for secure engagement with the elongate bundles  8  (shown in phantom). The mount member  14   c  further includes a base surface  28 . As shown in FIG. 22, the mount member  14   c  is spatially located away from the support surface  11   b . However, it should be noted that the base surface  28  may be adapted for supporting engagement with the support surface  11   b  of the metallic structural member  12 . The mount member  14   c  may be further provided with an interior web  51 . Interior web  51  provides added structural support to the mount member  14   c.    
         [0069]    As illustrated particularly in FIGS. 24 and 25, it can be seen that the bundle support surface  54  preferably includes an arcuate profile shape adapted to provide a snap fit for a bundle  8  secured within (see also FIG. 22). As such, the bundle support surface includes a compressible tab portion  56  that compresses to allow the bundle  8  to be snapped into the arcuate bundle support portion  54  and retains the bundle  8  after insertion. This arrangement creates a protective surrounding for the bundle  8  to minimize pinching and crushing of the bundle  8 . The mount member  14   c  is further preferably provided with a ramped portion  58  for facilitating insertion of a bundle  8  into the bundle support area. As seen particularly in FIG. 25, the mount member  14   c  may include a stud aperture  20  having an irregular, generally undulating, inner surface  36 . Further, the assembly includes a stud weld fastener  22  having an irregular portion  22   d  located intermediate the extension  22   a  and the base  22   b . The irregular portion  22   d  is configured for mating engagement of the irregular, generally undulating inner surface  36  of stud aperture  20 . FIG. 24 a  shows the embodiment of FIGS.  2225  with modified base  22   b  having pointed end  50 .  
         [0070]    Referring now to FIGS.  26 - 29 , inclusive, yet another embodiment mounting assembly  10   d  may be seen. As seen, the mount member  14   d  depicted in these views provides a cradle clamp device. The cradle clamp mount member  14   d  includes an open-ended loop  60  having first and second end portions  62   a ,  62   b  shaped and dimensioned to encircle a bundle  8  (not shown). The cradle clamp mount member  14   d  further includes a primary latch structure. In the illustrated embodiment, the primary latch structure takes the form of serrations  19  on one end  62   b  of the loop  60 , and an interlocking tab or pawl  66  formed at the other end  62   a . The flexible band  60  further includes a pivotable live hinge area  64  positioned between and integrally formed with the first and second end portions  62   a ,  62   b . During the encircling of the cradle clamp mount member  14   d  around the elongate bundle  8 , the hinge portion  64  allows the ends  62   a ,  62   b  to move toward each other for locking engagement of the serrations  17  and the pawl  66 . As illustrated particularly in FIG. 28, the preferred primary latch structure  66  is seen as a pawl device  66  provided at end  62   a  of the open-ended loop  60 . The pawl structure  66 , as detailed in FIG. 28, is adapted to receive a serrated strap  68  extending from the end  62   b  of the loop  60 . As observed in FIG. 28, the mount member  14   d  may include a stud aperture  20  having an irregular, generally undulating, inner surface  36 . Similarly to the embodiment shown in FIGS.  13 - 15   a , inclusive, the assembly seen in FIG. 28 includes a stud weld fastener  22  having an irregular portion  22   d  located intermediate the extension  22   a  and the base  22   b . The irregular portion  22   d  is configured to mating engagement of the generally undulating, irregular inner surface  36  of stud aperture  20 . FIG. 28 also shows a modified base  22   b  having an optional pointed end  50 .  
         [0071]    As seen particularly in FIG. 27, after the loop  60  is placed around a bundle  8  to be secured (not shown), the serrated strap  68  is passed through the pawl structure  66  to tighten the loop  60  around the bundle  8 . A plurality of serrations or teeth  19  on the strap  68  prevents withdrawing movement of the strap  68 .  
         [0072]    The cradle clamp mount member  14   d  may further include at least one cable tie aperture  24  for receiving cable ties (not shown in these views), for securing additional elongate items to the mount  14   d , and a through hole passage  69 . Swivel mount hole  70  may be included for receiving additional mounting devices (devices not shown).  
         [0073]    Preferably, all these structures have integrally formed cooperating elements, and the clamp  10  is molded as a unitary structure in a single manufacturing step.  
         [0074]    Referring now to FIGS.  30 - 32 , another alternative embodiment mounting assembly  10   a  is shown. As viewed particularly in FIG. 31, the mount member  14   a  may include an arm  40  (FIG. 30) having an upper surface  40   a  including a countersunk portion  34 . Countersunk portion  34  may be adapted to receive the radially extending ferrule  22   c  of stud fastener  22 . As seen, the countersunk portion  34  further includes a beveled portion  21  and the stud aperture  20  includes a relatively constricted portion  72 . The contour of the stud aperture  20  is adapted to receive a stud weld fastener  22  having a radially extending ferrule  22   c  and a relatively constructed portion  74 . The relatively constricted portion  74  of the stud weld fastener is preferably located intermediate the ferrule  22   c  and the base portion  22   b . As may be seen in these views, placement of the ferrule  22   c  in countersunk portion  34  allows the upper surface  40   a  of arm  40  to remain relatively smooth. Further, as illustrated in FIG. 32, the stud weld fastener  22  may include a base portion  22   b  having a sharply pointed end  50 . As mentioned with reference to previous embodiments, a pointed end  50  may be desired, when for example, the metallic structural member  12  is painted and it is necessary to pierce the treated surface immediately prior to welding.  
         [0075]    It has been noted in the embodiments that the extension  22   a  may be removed after welding. While this is possible and contemplated, it is not necessary for a bundle to be secured to the assembly, especially when the extension does not interfere with the bundle.  
         [0076]    The foregoing is considered as illustrative only of the principles of the invention. Furthermore, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described. While the preferred embodiment has been described, the details may be changed without departing from the invention, which is defined by the claims.
