Definitions

  • the present invention relates generally to the fastening of objects using plastic fasteners and relates more particularly to a novel plastic fastener, a novel fastener clip, a novel fastener dispensing tool and a novel method of fastening objects.
  • Certain articles of clothing are often packaged and sold in a folded condition so as to minimize any wrinkling of the article and so as to present the article in an otherwise flattering manner.
  • the article is maintained in a folded condition by means of one or more straight metal pins, each of said straight metal pins typically comprising an elongated shaft terminating at one end in a sharp tip designed to penetrate the article and at the other end in a rounded head designed not to penetrate the article.
  • the article is folded, and a plurality of said pins are used to maintain the article in its folded condition by securing the article to itself at a plurality of different locations.
  • one or more of said pins are additionally used to secure the shirt to a piece of cardboard or to a similar backing material.
  • the act of using straight metal pins to maintain an article of clothing in a folded condition is typically referred to in the art as "shirt-pinning.”
  • shirt-pinning Although straight metal pins have achieved widespread use in maintaining articles of clothing in a folded condition, certain shortcomings are associated therewith.
  • One such shortcoming is that no suitable tool exists for dispensing such pins into an article of clothing; consequently, the pins must be inserted manually. As can readily be appreciated, the repeated insertion of such pins into articles of clothing, over time, can become both physically and mentally taxing.
  • Plastic fasteners of the type comprising an elongated flexible filament having a first enlargement at one end thereof and a second enlargement at the opposite end thereof are well-known and have been widely used in the attachment of merchandise tags to articles of commerce, in the coupling or re-coupling of buttons to garments, in the binding of a shoe upper during the process of shoe-lasting, and in various packaging applications.
  • plastic fastener see, for example, Fig.1 of U.S. Patent No.
  • the first enlargement has the shape of a first transverse bar and the second enlargement has the shape of a paddle or the shape of a second transverse bar, the first transverse bar and the paddle (or second transverse bar) extending in planes parallel to one another.
  • the first enlargement has the shape of a transverse bar and the second enlargement has the shape of a knob or pin head.
  • plastic fastener see, for example, U.S. Patent No.
  • the first enlargement has the shape of a transverse bar or the shape of a plug and the second enlargement has the shape of a socket, said socket being adapted to receive said transverse bar or said plug.
  • Plastic fasteners of the various types described above are typically molded as parts of a unitary fastener clip. An example of such a fastener clip is disclosed in U.S. Patent No. 3,733,657, which patent is incorporated herein by reference.
  • the clip of the aforementioned '657 patent includes a plurality of fasteners, each of said fasteners comprising a flexible filament having a first transverse bar (or "cross-bar") at one end thereof and a paddle or a second transverse bar (or “cross-bar”) at the opposite end thereof, the transverse bar and the paddle (or second transverse bar) of each fastener extending in planes parallel to one another.
  • the fasteners are arranged relative to one another so that the respective transverse bars are spaced apart and oriented side-by-side and parallel to one another and so that the respective paddles (or second transverse bars) are spaced apart and oriented side-by-side and parallel to one another.
  • the clip of the foregoing '657 patent also includes a runner bar, said runner bar extending perpendicularly relative to the respective transverse bars and being connected to each of the transverse bars by a severable connector.
  • the clip of said '657 patent further includes a severable member interconnecting each pair of adjacent paddles (or second transverse bars).
  • DENNISON ® SWIFTACH ® fastener clips comprising fasteners of the type having a cross-bar at one end of a flexible filament and a paddle at the opposite end of the flexible filament are generally made of polypropylene or nylon and are typically used to attach merchandise tags and the like to articles of clothing.
  • the filaments of such fasteners are typically at least about 12.5 mm in length.
  • DENNISON ® SWIFTACH ® fastener clips comprising fasteners of the type having a first cross-bar at one end of a flexible filament and a second cross-bar at the opposite end of the flexible filament are made of nylon and are used to attach merchandise tags and the like to a wide variety of articles of commerce.
  • fasteners are used in shoe-lasting applications and in packaging applications, where the high tensile strength afforded by the use of nylon in the fastener is desirable.
  • the filaments of such fasteners are typically at least about 6.35 mm in length.
  • the fastener stock comprises two undivided elongated and continuous plastic side members having a plurality of plastic cross links coupled to and between each of said side members each of the links being preferably spaced equidistantly apart from each other
  • the fastener stock is designed to be separated or divided, e g , by cutting severing, rupturing or shearing the side members, to provide a plurality of fasteners, each of said fasteners preferably having a substantially H shape
  • PLASTIC STAPLETM fasteners are typically made of polyurethane and are often used to attach tags, at two distinct points, to pants and similar clothing articles It is the understanding of the present inventors that, for a limited time in the past, a third party used PLASTIC STAPLETM fasteners to "pin" shirts, albeit not dress shirts or other shirts of a fine material, so as to maintain the shirts in a folded condition It is the understanding of the present inventors that the aforementioned securing was achieved using a dual needle fastener dispensing tool of the type disclosed in U S Patent No 4,533,076 and was performed by folding the shirt, inserting both needles of the tool entirely through the folded-over article and then dispensing both cross-bars through the needles and the folded article so that both cross-bars were positioned on one side of the article
  • Tools for dispensing individual fasteners from multi-fastener clips of the two different types described above are known, examples of such tools including the Dennison ® Mark II" SWIFTACH ® tool, as well as those tools disclosed in U S Patent Nos 5 772,073, 5,683,025, 5,024,365, 4,533,076, 4,456,161 , 4,121 ,487, and 4,456,123, all of which are incorporated herein by reference.

  • Fastener 11 which is a unitary structure preferably made by molding, comprises a flexible filament 13 When molded, filament 13 has a length A, of about 1 65 mm and a diameter d 1 of about 0 4 mm, filament 13 is thereafter stretched in the conventional manner to a length of approximately 4 3 mm and a diameter of approximately 0 2 mm It should be noted that, even though, in the present embodiment, filament 13 has a generally cylindrical shape, filament 13 need not be cylind ⁇ cally shaped and may take a variety of shapes, including those specified in commonly-assigned co-pending U S Patent Application Serial No 09/416,784 Fastener 11 also comprises a first cross-bar 15 and a second cross-bar 17, cross-bar 15 being disposed at a first end of filament 13, cross-bar 17 being disposed at a second end of filament 13, cross-bars 15 and 17 being parallel to one another Each of cross-bars 15 and 17 has a length l 2 of approximately 1 78 mm, a width w 1 of approximately 0
  • cross-bars 15 and 17 are shaped so as to have flat inner surfaces 15-1 and 17-1 , respectively, proximate to filament 13 and convex outer surfaces 15-2 and 17-2, respectively, distal to filament 13, cross-bars 15 and 17 need not be so shaped
  • cross-bars 15 and 17 may take a variety of forms, including those of the enlarged ends described in U S Patent Application Serial No 09/416,784
  • Fastener 1 1 is preferably made of a polyurethane that gives filament 13 a tensile strength of about 2 pounds.
  • said polyurethane is not the only type of material of which fastener 11 may be made and that other plastic materials (or combinations of materials) capable of providing filament 13 with a tensile strength in the range of about 2-4 pounds (or whatever tensile strength is desirable based upon the particular use to which fastener 11 is put) are also suitable for purposes of the present invention. It is to be noted that, because filament 13 is made of a polyurethane, it has a certain degree of elasticity - a property which may be desirable in certain applications. Referring now to Figs. 2(a) and 2(b), there are shown partially-exploded perspective and partially-exploded side views, respectively, of one embodiment of a fastener clip constructed according to the teachings of the present invention, the fastener clip being represented generally by reference numeral 31.
  • Clip 31 which is a unitary structure preferably made by molding, comprises a plurality of fasteners 11-1 through 11-3, fasteners 11 being arranged in a parallel, side-by-side, spaced orientation. Although only three fasteners 11 are shown in clip 31 , it is to be understood that the number of fasteners 11 in clip 31 is illustrative only and could be increased or decreased without departing from the spirit or scope of the present invention. (In fact, in a preferred embodiment, clip 31 comprises one hundred twenty-five fasteners 11.)
  • Clip 31 also includes a first plurality of severable connector posts 33-1 and 33- 2 and a second plurality of severable connector posts 35-1 and 35-2, connector posts 33 connecting the mutually-opposing sides of adjacent cross-bars 15 at their approximate midpoints and extending in a substantially perpendicular direction relative to the longitudinal axes of cross-bars 15, connector posts 35 connecting the mutually-opposing sides of adjacent cross-bars 17 attheirapproximate midpoints and extending in a substantially perpendicular direction relative to the longitudinal axes of cross-bars 17.
  • FIGSide, top and front views of an individual fastener 11 , together with its associated connector posts 33 and 35, are shown in Figs. 3(a) through 3(c), respectively.
  • connector posts 33 and 35 have a length of approximately 0.25 mm.
  • Connector posts 33 and 35 are strong enough to maintain the connection between adjacent fasteners 1 1 in clip 31 prior to the dispensing of individual fasteners 11 from clip 31 and, yet, are weak enough to be severed by the conventional severing action of a fastener dispensing tool.
  • connector posts 33 and 35 have a certain degree of flexibility; consequently, because of the arrangement of posts 33 and 35 relative to cross-bars 15 and 17, respectively, adjacent fasteners 11 in clip 31 are permitted to pivot relative to one another, thereby enabling clip 31 to be bent into an arcuate shape.
  • posts 33 and 35 preferably have a conical or tapered transverse cross-section that decreases in diameter from the fastener about to be dispensed (e.g., fastener 11-1 ) to the next fastener in the clip 31 (e.g., fastener 11-2) so that very little or nothing of the severed posts 33 and 35 that once connected the fastener about to be dispensed to the fastener previously attached to it remain on the about-to-be-dispensed fastener.
  • the fastener about to be dispensed by the tool e.g.
  • fastener 11 -1 is able to sit substantially flush within a tool used to dispense the fastener. It should be understood, however, that the above embodiment is merely a preferred embodiment and that posts 33 and 35 need not be conical or tapered and, instead, may take a variety of shapes.
  • Clip 31 further includes an extra pair of cross-bars 37 and 39, cross-bars 37 and 39 being identical to cross-bars 15 and 17, respectively, except for the fact that cross-bars 37 and 39 are not disposed at the ends of a flexible filament.
  • Cross-bars 37 and 39 are arranged in a parallel, side-by-side, spaced orientation from cross-bars 15 and 17, respectively, of the last fastener 11 of clip 31 (in the present embodiment, fastener 11-3) and are severably connected thereto by connector posts 33-3 and 35- 3, respectively.
  • Connector post 33-3 is identical to connector posts 33-1 and 33-2
  • connector post 35-3 is identical to connector posts 35-1 and 35-2.
  • Cross-bars 37 and 39 serve to keep the last fastener of clip 31 properly oriented while it is being dispensed using the fastener dispensing tool described below.
  • clip 31 does not include a runner bar This may be advantageous since the runner bar of a fastener clip typically has no use once the fasteners originally attached thereto have been dispensed therefrom As a result, the detached runner bar typically represents economically and environmentally undesirable waste material
  • severed connectors previously used to connect fasteners to a runner bar and still remaining on the runner bar after the fasteners have been detached therefrom often have an acute end which may undesirably snag on and damage merchandise when fasteners from the fastener clip are dispensed into such merchandise with a conventional fastener dispensing tool
  • Clip 31 may be made by injection molding, preferably using polyurethane or a similar material According to a preferred embodiment, clip 31 is made by forming a fastener clip analogous to clip 31 but further comprising a runner bar severably connected to each of cross-bars 15 (see, for example, fastener clip 11 of U S S N 09/464,022) and then by severing said runner bar from each of cross-bars 15 and removing the remnants of any connectors connecting said runner bar to cross-bars 15
  • runner bar-containing fastener clips could be substituted for runner bar-less clip 31 and used with an appropriately dimensioned version of a conventional fastener dispensing tool of the type adapted for use with runner bar-containing clips (an example of such a tool being an appropriately dimensioned Dennison ® Mark II TM SWIFTACH ® tool)
  • Tool 51 includes a hollow, gun-shaped casing 53 casing 53 comprising a right half 55 (which is shown separately in Figs 6(a) through 6(d)) and a left half 57 (which is shown separately in Figs 7(a) through 7(d))
  • Halves 55 and 57 which may be fabricated from any convenient durable material such as molded plastic, are joined together by a plurality of screws 58 and jointly define a handle portion 59 and a barrel portion 61
  • a plurality of screws 58 are joined together by a plurality of screws 58 and jointly define a handle portion 59 and a barrel portion 61
  • an oval-shaped recess 63-1 is provided on the outer surface of the barrel portion of right half 55, and a corresponding oval- shaped recess 63-2 is provided on the outer surface of the barrel portion of left half 57

  • Inserts 64-1 and 64-2 may bear a logo or the like and/or may have a rubberized or gripping outer surface to prevent tool 51 from sliding across a table when placed thereon
  • a window 65-1 is provided in the barrel portion of right half 55, and a matching window 65-2 is provided in the barrel portion of left half 57
  • Windows 65-1 and 65-2 permit a user to monitor the status of a fastener clip 31 disposed inside casing 53
  • windows 65-1 and 65-2 provide an opening through which cross-bars 37 and 39 of a clip 31 may exit casing 53 once a clip 31 has been completely spent
