    CROSS REFERENCE TO RELATED ORDERS
    [001] This application claims the benefit of United States Interim Application Serial No. 61/837,256, filed June 20, 2013, and also the benefits of United States Interim Application Serial No. 61/932,523, filed on 28 of January 2014. FIELD OF THE INVENTION
    [002] The present invention relates generally to fasteners, and more particularly to clamping fasteners used to secure one component to another component, such as, for example, fasteners used in the automotive industry to fasten internal panels, internal and external molding and chips, and similar to one another and/or to related or underlying structures. A fastener of this type is sometimes referred to as a fastener clamp. FUNDAMENTALS OF THE INVENTION
    [003] Different types of tightening fasteners are known for use in different environments and for different purposes. A basic design for a snap fastener includes a body that is inserted into aligned openings in the first and second articles, or into an opening in at least one of the articles. The fastener body includes a collar or head larger than the opening or openings in the articles or article, and defective portions or legs that yield as the body is inserted through the openings and reconnected when fully through the openings. The legs are curved outward to define a maximum diameter greater than the opening(s) into which the fastener is inserted. During fastener installation, the legs deflect inward to pass through the opening and then curve outward as the maximum diameter portion passes through the opening. The articles to be secured by fasteners can be sandwiched between the collar and the bent defect parts of the body. A fastener pin is inserted into and retained by the body after the body is seated in place on the articles. Pin wedges against defective portions of the body to hold the body in place, and may further include additional defective elements to increase the retaining force of the fastener.
    [004] In some fasteners the body and pin are independent components, completely separate from each other before installation. In other tightening fasteners, the body and pin have a pre-installed position in which the pin is held in the body but does not interfere with installation of the body into a workpiece. The body is first inserted and seated in place by pushing on the head of the body. Once the body is fully seated, the head of the pin is pushed in until the pin is also fully seated in the body. It is known to provide the head of the body and the head of the pin of substantially the same size. It is also known in some applications to provide a fastener in the channel or in a shallow well or cavity to conceal and/or protect the body and pin heads.
    [005] Known design deficiencies for this purpose include the in-ability of the pin to stay in a pre-drive position until the body is firmly seated. If the fastener pin descends from the fastener body, the fastener pre-assembly advantages are lost. When assembling the articles and securing, if the fastener pin is moved axially inward too far from the fastener body, before the body is firmly seated in the article receiving the body, the pin and body may become locked, without the body being seated correctly. The articles to be secured by the fastening element are not held tightly against each other if the body is not fully inserted and seated where desired. The pin's inability to stay in the pre-trigger position can be improved by increasing the interference between the pin and the body; however, this can make the final connection achieved by driving the pin into the body more difficult. Generally, it is desirable for the fastener to lead easily, but be securely retained. Consequently, it is often necessary to drive the body, pushing only against the body collar and not against the head of the pin. This can be a little awkward in many mounting situations where the body collar is partially covered by the head of the pin. Many known fixture designs do not disassemble easily, and are not reusable. This can be problematic if the fastener is used in an assembly that may require periodic disassembly. Furthermore, disassembly may result in damage, or complete separation of the fastening components, making reuse impossible or inconvenient.
    [006] It is also known to provide a head on the shaped pin for connecting to another component or thing to be held in position by the fastener. The body can be attached to one part and the pin to another. By holding the pin and body together, the separate pieces joined to the body and pins are then held in position relative to each other,
    [007] Fasteners of this type have been used to advantage and are accepted in many applications. However, such fasteners are not without inadequacies and shortcomings for some uses and applications. Consequently, clamping fasteners having different characteristics and appearance are needed. SUMMARY OF THE INVENTION
    [008] The present invention solves problems of other models by providing a snap-in fastener that includes a pin body and that remains securely in a pre-assembled condition but is easily installed for use.
    [009] In one form of an embodiment, a snap fastener is provided with an eyelet fastener having an eyelet head that defines a hole through and a plurality of legs that extend from the head of the eyelet. A fastener pin has a pin head and a shaft configured for insertion through the hole in the eyelet head. The eyelet and pin has a relative pre-installation arrangement in which the pin is held in the eyelet with the legs in a relaxed state; and the eyelet and pin has a relative arrangement fitted in which the pin rotates the legs outward to define a larger outer diameter of the legs than with the legs in the relaxed states thereof.
    [010] In another embodiment thereof, a snap fastener is provided with an eyelet fastener having an eyelet head defining a through hole and a plurality of legs extending from the eyelet head, and a fastener pin having a pin head of a diameter larger than the hole and a shaft configured for insertion through the hole in the head of the eyelet. Eyelet legs have inward-facing feet. The pin axis includes a neck most distal and a neck most proximal to the head, the most distal neck being a first diameter and the most proximal neck being a second diameter larger than the first diameter. The eyelet and pin have a relative pre-installation arrangement with the eyelet secured to the pin by inwardly directed foot tips positioned around a more distal neck, and a relative installed arrangement with the foot tips positioned around the neck more proximal.
    [011] The advantages of at least some forms of snap-on fastener disclosed herein are that the snap-on fastener is easier to handle and install.
    [012] Other features and advantages of the invention will become apparent to those skilled in the art upon review of the following detailed description, claims and drawings, in which like numbers are used to designate like features. BRIEF DESCRIPTION OF THE DRAWINGS

The invention is capable of other modalities and of being practiced or being carried out in various ways. Furthermore, it is understood that the phraseology and terminology used herein is for the purpose of description and should not be considered limiting. The use herein of "including", "comprising" and variations thereof is intended to encompass the items listed below and their equivalents, as well as additional articles and their equivalents. DETAILED DESCRIPTION OF THE PREFERRED MODALITY
    [023] Referring now more specifically to the drawings and Fig. 1 in particular, an exemplary snap-on fastener 10 is shown. Fastener 10 includes a fastener eye 12 and a fastener pin 14. Fastener eyelet 12 is configured to accommodate within a hole or holes in an article or articles to be held together by the snap fastener 10. Fastener pin 14 is configured for insertion of fastener eyelet 12 to inhibit fastener eyelet 12 from dislodging from the articles in which it is seated. Fastening eyelets 12 and fastening pin 14 can be made of plastic by various molding techniques, and can be formed from the same or different materials. Those skilled in the art will readily understand that the fastener eyelet 12 and fastener pin 14 can be molded as a single piece, with the fastener eyelet 12 and fastener pin 14 being connected by one or more easily broken frangible connections to reposition the relative relationship between the eyelets 12 and fastener pin 14 from the molded relationship as shown in Fig. 1 to the pre-installed relationship shown in Fig. 2.
    [024] Fastener eyelets 12 include an eyelet head 20 and a plurality of legs 22, four of these legs 22 being shown in the exemplary embodiment, each leg extending axially from one side of the grommet head 20. In the exemplary embodiment shown , the four legs 22 are independent and spaced apart from each other. Thus, elongated spaces 24 are defined between adjacent legs 22. Spaces 24 collectively join into an open space located centrally between all legs 22. Eyelet head 20 defines a central opening 26 therethrough.
    [025] Each leg 22 includes an inwardly angled distal segment 28 having an inwardly directed foot tip 30 of the inner surface thereof. Inwardly angled distal segments 28 collectively provide an inlet end for the fastener eyelet 12 that is significantly narrower than the hole diameters in the articles in which the fastener is to be installed. Consequently, fastening eyelets 12 can be easily positioned in a hole for installation. The proximal portions of the legs 22, which comprise a substantial axial extension of each leg 22, define an outer diameter not significantly greater than the diameter of a hole in an article in which the fastener is being installed, and may define a diameter slightly smaller than the diameter of the hole into which the fastener is being installed. Consequently, with the legs 22, in natural, unsolicited conditions, the fastener eyelet 12 easily slides into its fully installed position until the eyelet head 20 engages the surface of the article adjacent to the hole in which the fastener is installed.
    [026] Eyelet head 20 in exemplary mode defines a substantially circular perimeter, but may also have other shapes. At the transition from the eyelet head 20 to the individual legs 22, a recess 32 is formed on the outside thereof, thus defining a position for controlled folding. Under relaxed conditions of legs 22, central opening 26, a proximal inner surface 34 of each leg 22 is inwardly angled toward a waist 36, wherein there is a transition to an outer angled surface 38 generally extending from waist 36 to the toe tip 30. Thus, under the relaxed conditions of legs 22, the internal space defined by the inner surfaces of legs 22 has an overall hourglass configuration. Legs 22 have outer end edges, sharp 40.
    [027] The shape of the fastening eyelet 12 just described is just exemplary, and the invention can be used with other types of bodies. For example and not by way of limitation, eyelet legs can be of different sizes and shapes; more than four legs or less than four legs can be used.
    [028] Fastener pin 14 includes a pin head 50 and a shaft 52 that extends axially from pin head 50. Shaft 52 is configured for insertion through central opening 26 of eyelet head 20 to be received between legs 22. Shaft 52 includes an inverted tapered tip 54 including an apex 56 and a base 58. From base 58, a first, more distal neck 60 joins from the base 58 of the tapered tip 54 to a second inverted tapered intermediate body 62, which it is integral with its apex at the first neck 60 and has a second base of the tapered body 64. Thus, the base 58 of the taper tip 54 is exposed outwardly of the first neck 60. The second most proximal neck 66 is defined between the base 64 of the second tapered body 62 and an outer sloping shoulder 68. Thus, base 64 is exposed outwardly of the second most proximal neck 66. The first most distal neck 60 is narrower than the second most proximal neck 66. The surface of the center body slightly angled p The inside 70 transitions at a waist 72 to a larger, externally angled surface 74 that transitions relatively abruptly to a proximal axis segment 76.
    [029] The outer end of the pin 14 defines a structure for engaging work pieces or items to be performed by fastener 10. In exemplary embodiment, a skirt 78 and flange 80 are provided spaced apart from the pin head 50.
    [030] A well 82 extends axially in the proximal segment of the axle 76 of an opening in the head 50. Well 82 is configured to receive a tool or other instrument for pushing the fastener pin 14 into the fastener eyelet 12.
    [031] The cross-sectional view of Fig. 3 illustrates the pre-installed condition of the fastener 10. The shapes and dimensions of the fastener ring 12 and the fastener pin 14 are such that the conical tip 54 extends beyond the ends of the legs 22, second tapered body 62 is generally disposed in the inner zone or space between waists 36 and foot tips 30, with foot tips 30 extending into the space formed around first neck 60 between tapered tip 54 and second conical body 62. Consequently, the legs 22 remain in their natural, relaxed condition. Meanwhile, pin 14 is retained in grommet 12 by the exposed area of base 58 engaging outer end edges 40 of legs 22 to limit withdrawal of pin 14 from grommet 12. Skirt 78 abuts over insertion of pin 14 into grommet 12. Width The proximal axis segment 76 with respect to the width of the central space defined between the legs 22 places the sloping surfaces 34 and 74 opposite each other, thus keeping the pin 14 in its pre-installation position with respect to the eyelet 12.
    [032] The cross-sectional view of Fig. 4 illustrates the fully installed condition for the fastener 10. Fastener pin 14 was moved by the force being more deeply and positioned in relation to the fastener eyelet 12 such that second conical body 62 now extends beyond outer end edges 40 of legs 22. Feet tips 30 extend into the space formed around second neck 66, and the wider upper region of the proximal segment of shaft 76 engage surfaces 34. This does with the legs 22 bending away from the second undercuts 32, thus defining a larger maximum diameter around the legs 22, then when the legs 22 are allowed to remain in their relaxed condition. With a suitably sized hole 84 in a workpiece 86, grommets 12 are securely held in workpiece 86. If the diameter defined around legs 22 in the relaxed, unsolicited state of the legs is slightly less than, equal to , or not significantly larger than the diameter of hole 84, grommets 12 can be easily inserted into hole 84, if pin 14 is kept in the pre-installed condition shown in Fig. 3. It should be noted that pushing the pin 14 does not result in outward bending of the legs 22 until the head of the eyelet 20 engages the workpiece 86, so that even more axial force against the pin 14 causes the pin 14 to move from the pre-installed condition of Fig. 3 for the fully installed condition shown in Fig. 4.
    [033] Fig. 5 shows a simple modification by the addition of fastener 10. A seal body 90 is provided under skirt 78 to establish an environmental seal and/or a resilient pad against the workpiece 86. The seal of body 90 can be applied by overmolding.
    [034] Fastener 10 is removable and reusable. When sufficient extraction force is applied to withdraw the fastener pin 14 relative to the fastener eyelet 12, the facing angled surfaces will slide relative to one another, thereby withdrawing the pin and moving back to the relative positions shown in Pre-installation condition of Fig. 3. The grommet can then be easily removed from the workpiece, item or article in which it is installed. However, even when so removed, grommets 12 and pin 14 remain firmly attached to each other, as described in relation to the pre-installed position. From this position, fastener 10 can be reused and reinstalled. Desirable holding force can be designed for the fastener by selecting various dimensions and angles.
    [035] Figs. 6 to 9 show a second embodiment of a fastener 110 having similar characteristics to fastener 10, including an fastener eye 112 and a fastener pin 114. Accordingly, fastener structures 110 similar to those of fastener device 10 are designated with similar reference numbers in the "100" series of numerals. Fastening eyelets 112 include an eyelet head 120, a plurality of legs 122, separated by spaces 124 and defining a central opening 126. In the exemplary embodiment, four legs 122 are used, but more legs or fewer legs may also be used. Angular distal segments 128 in each leg 122 are slightly enlarged towards the ends thereof and define inwardly directed corner tips 130 instead of the pronounced foot-like projections of the tips 30 of legs 22. Recesses 132 established between head 120 and legs 122 allow for flexion and outward deformation of legs 122 to engage the eyelet 112 against a hole 184 in a workpiece 186. Inwardly sloping surfaces 134 extend to a transition from waist 136 to outwardly sloping surfaces 138 toward the edges of outer end 140 of feet122.
    [036] Fastener pin 114 includes a pin head 150 and a pin shaft 152. Shaft 152 includes an inverted taper point 154 having an apex 156 and a base 158. A first neck 160 connects the base 158 of the taper point 154 to a second intermediate inverted tapered body 162 having a second base 164. A second neck 166 connects to a shoulder 168 leading to inwardly angled center body surfaces 170 and a waist 172. Waist 172 transitions to an angled outer surface 174 leading to a proximal shaft segment 176. Pin 114 further includes a skirt 178 and a flange 180 and a well 182.
    [037] Pin 114 differs from pin 14, in that some of the angled surfaces are more gradual, and the transitions between the angled surfaces angled outwards and inwards are less abrupt and are more rounded. Thus, fastener 110 can be disconnected more easily and with less damage, thus facilitating reuse.
    [038] Fig. 7 illustrates a molded fastener 110 condition, with pins 114 connected to sleeve 112 by breakable connections between eyelet 154 and tapered head tip 120. From this condition, pin 114 can be advanced to a pre-installed condition in which eyelet 112 and pins 114 are separate but engaged with each other, advancing the pin and fracturing the breakable connections.
    [039] A pre-installed condition of fastener 110 is similar to fastener 10. Tapered tip 154 extends beyond the ends of legs 122, second tapered body 162 is generally disposed in the inner area or space between waists 136 and tips inwardly directed 130, with inwardly directed spikes 130 extending into the space formed around first neck 160 and outer end edges 140 directed in base 158 of tapered tip 154 away from neck 160. Thus, 122 legs remain in their natural, relaxed condition. However, pin 114 is retained in grommet 112 by the exposed area of base 158 engaging outer end edges 140 of legs 122 to limit withdrawal of pin 114 from grommet 112. Skirt 178 limits on insertion of pin 114 into grommet 112. The width of the proximal axis segment 176 relative to the width of the central space defined between the legs 122 places the sloping surfaces 134 and 174 opposite each other, thus keeping the pin 114 in its pre-installation position relative to the grommets 112.
    [040] A fully installed condition of fastener 110 (Fig. 9) is similar to fastener 10. Fastener pin 114 has been moved by force to be more deeply positioned relative to fastener and grommets 112 such that second conical body 162 now extends beyond the outer end edges 140 of the legs 122. Inwardly directed tips 130 that extend into the space formed around the second neck 166, and the wider upper region of the proximal axis segment 176 engages surfaces 134 of eyelets 112. This causes legs 122 to bend outwardly into recesses 132, thus defining a larger maximum diameter around legs 122 then when legs 122 are allowed to remain in their relaxed condition. With a suitably sized hole 184 in a workpiece 186, grommets 112 are securely held in its workpiece 186. If the diameter defined around legs 122 in the relaxed, unbiased state of the legs is slightly less than, equal to, or not significantly larger than the diameter of hole 184, grommets 112 can be easily inserted into hole 184, if pin 114 is kept in the pre-installed condition.
    [041] Fastener 110 is removable and reusable. When sufficient extraction force is applied to withdraw the fastener pin 114 relative to the fastener eyelet 112, the facing angled surfaces will slide relative to one another, thereby withdrawing the pin and moving back to the relative positions of the condition. of pre-installation. The grommet can then be easily removed from the workpiece, item or article in which it is installed. However, even when so removed, securing grommets 112 and pin 114 remain securely connected to each other, as described in connection with the pre-installed position. From this position, fastener 110 can be reused and reinstalled.
    [042] Fasteners 10, 110 provide several features and advantages. The sloping surfaces of pins 14, 114 and eyelets 12, 112 act as ramps that facilitate installation and connection. Contact between the outer surface of the grommet legs and the inner surface of the workpiece hole results in fasteners and panels being retained to a fixture panel. Skirts 78, 178 provide tension against articles being protected, and the sloping surfaces of the eyelets 12, 112 enable fasteners 10, 110 to be installed and connected to panels of different thicknesses. Fasteners in pre-installed condition can be installed as a set on an item or thing, which is then attached to a second item or thing by inserting the eyelet for the second item or thing and installing the first item or thing towards the second item or something to advance the pin in the eyelet to the fully installed condition. Alternatively, pins 14, 114 can be connected to one item or thing, and grommets 12, 114 to a second item or thing, so that the first and second articles or things can be secured relative to each other by simple pin engagement 14, 114 in eyelets 12, 112. Four contact points are provided when four legs 22, 122 are used, providing security, rigidity and natural centering in holes 84, 184. Installer response can be provided by both feel and sound as surfaces angled and transitions move from one position to another position and as the pins 14, 114 reach their final positions installed in eyelets 12, 112. For example, inwardly directed tips 30, which travel 130 beyond the outer edges of the second tapered base 64, 164 can provide a distinct feel and sound. Installation and connection is easy, even if a drilling process to drill holes 84, 184 results in burrs or malformations in the holes.
    [043] Although the fasteners 10, 110 described herein are multi-piece, including both an eyelet 12, 112 and a pin 14, 114; Components are installed as a single unit, pre-assembled, and can be removed as a single unit, while still assembled. Consequently, grommets 12, 112 remain connected to pins 14, 114; different from when removing known pin and grommet connectors when the grommets remain on the product when the pin is removed. Consequently, the present fastener can be removed when attached items or things are accessible from only one side, and it can be reinstalled multiple times while retaining substantially the same retention capabilities.
    [044] Variations and modifications of the foregoing are within the scope of the present invention. It is understood that the invention described and defined herein extends to all alternative combinations of two or more of the individual features mentioned or evident from the text and/or drawings. All these different combinations constitute the various alternative aspects of the present invention. The embodiments described herein explain the best known modes for practicing the invention and will enable others skilled in the art to use the invention. The claims are to be interpreted as including alternative modalities to the extent permitted by the prior art.
