Title: Retention push pin for temporary mounting in vehicles

Description:
TECHNICAL FIELD 
     The present disclosure relates to the use of a push pin for mounting in a vehicle, and, more particularly, to a push pin configured to mount to the interior of a vehicle without adhesives or clamping. 
     BACKGROUND 
     Vehicle interiors, specifically instrument panels, may need to be protected from physical and environmental damage during the manufacturing process or during repair. Protective films may be placed over portions of the interior to protect the underlying components. Due to the varying geometry of the vehicle interiors, the protective films may not remain in place without some retention mechanism to fix them in a desired position. 
     Adhesives may be used to fix the films in a desired position. The adhesives, for example, an adhesive tape, may be applied to the film and a surface of the vehicle interior to couple the two and hold the film in position on the surface. The adhesives may hold the film in place and prevent physical or environmental damage to the underlying vehicle interior. However, when the adhesive is removed it may leave behind a residue on the vehicle interior. The residue may be difficult or in some cases, impossible to remove without damaging the vehicle interior. Further, the adhesive removal may require cleaning equipment and/or cleaning chemicals that can add additional expense to the vehicle manufacturing or repair operation. Alternatively, even if an adhesive does not leave a residue it may still leave behind an imprint, sometimes referred to as “ghosting” in the art, in which the outline of the adhesive is still visible on the interior surface even after removal. 
     Instead of adhesives, mechanical mechanisms, such as clamps, may be used to fix the film in a desired position. The clamps, for example, alligator clips, may retain the film in place by clamping a portion of the film to a structure on the interior of the vehicle such as an air conditioning vent. However, as the clamp applies pressure to the interior structure it may also risk damaging the interior structure. Further, the clamp can leave an indentation or notches in the surface of the interior structure if too much pressure is applied. Moreover, the clamp itself may break resulting in added expense to the vehicle manufacturing or repair operation. 
     Accordingly, there is a need for a mounting mechanism that does not require the use of adhesives or clamps and may be used on the interior surfaces of vehicles.

     DETAILED DESCRIPTION 
     The present disclosure relates to the use of a push pin for mounting in a vehicle, and, more particularly, to a push pin configured to mount to the interior of a vehicle without adhesives or clamping. 
     Unless otherwise indicated, all numbers expressing quantities of components, properties such as molecular weight, reaction conditions, and so forth used in the present specification and associated claims are to be understood as being modified in all instances by the term “about.” Accordingly, unless indicated to the contrary, the numerical parameters set forth in the following specification and attached claims are approximations that may vary depending upon the desired properties sought to be obtained by the examples of the present invention. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of the claim, each numerical parameter should at least be construed in light of the number of reported significant digits and by applying ordinary rounding techniques. It should be noted that when “about” is at the beginning of a numerical list, “about” modifies each number of the numerical list. Further, in some numerical listings of ranges some lower limits listed may be greater than some upper limits listed. One skilled in the art will recognize that the selected subset will require the selection of an upper limit in excess of the selected lower limit. 
     The embodiments described herein comprise the use of a push pin. The push pin may be mounted to an interior surface of a vehicle. In some embodiments the push pin may retain a film over the interior surface. In some alternative embodiments, the push pin may function as an accessory mount allowing for the holstering of vehicle and/or personal accessories on the interior of a vehicle. The push pin may mount to the interior of the vehicle without the use of an adhesive or a clamp. The term “clamp,” as used herein, generally refers to any clamp, clip, clasp, brace, vice, press or other similar such device. Although some examples may describe the use of the push pin for the interior of a vehicle, it is to be understood that the push pin may be used to mount to any opening in any surface in which the push pin may be inserted. As such, this disclosure explicitly contemplates the use of the push pin to retain, mount, or hold any object in any surface into which the push pin may be inserted. 
       FIG. 1  is an isometric illustration of a push pin, generally  5 . Push pin  5  comprises pin tip  10 , a head  15 , and at least one rib  20 . In some examples, at least a portion of pin tip  10  may be pointed and have a sharpened or generally tapered tip at the terminal end  25  farthest from the head  15 . In other examples, no portion of pin tip  10  may be pointed, and the pin tip  10  may comprise an elongated rod narrower than head  15  in diameter. Rib  20  is a ring-like circular protrusion projecting around the profile of the pin tip  10 . Rib  20  may be any shape (e.g., rib  20  may be ovoid having rounded edges). In the illustrated example, only one rib  20  is illustrated However, it is to be understood that push pin  5  may comprise any multiple of rib  20  as desired. Head  15  is illustrated as a planar circular shape on the opposing terminal end  30  from terminal end  25 . Head  15  may be any shape including, but not limited to, square, triangular, etc. 
       FIG. 2  illustrates a cross-section of push pin  5  (as discussed above and illustrated in  FIG. 1 ) when used to retain a film  35  on a surface  55  of a vehicle interior. When desired for use, pin tip  10  of push pin  5  may be inserted into an opening  40  made within film  35 . The pin tip  10  may be inserted into the opening  40  past the portion of pin tip  10  comprising the one or more ribs  20  such that the rib  20  is inserted into and through the opening  40 . In the illustrated example, push pin  5  is inserted into opening  40  to a sufficient depth that film  35  contacts the underside  45  of head  15 . Head  15  has a diameter greater than that of the diameter of opening  40  and prevents film  35  from sliding or being pulled past head  15 . Push pin  5  may then be inserted into an opening  50  in a surface  55  of a vehicle interior. The pin tip  10  may be inserted into the opening  50  past the portion of pin tip  10  comprising the one or more ribs  20  such that the rib  20  is inserted into and through the opening  50 . In the illustrated example, push pin  5  is inserted into opening  50  to a sufficient depth that the film  35  contacts the surface  55 . The opening  50  may be any opening in a surface  55  of a vehicle and is not limited to openings in the vehicle interior. An example of an opening  50  is an air conditioning vent. The push pin  5  is sized such that the pin tip  10  may easily pass through the opening  50 , but that the head  15  is too large in diameter to pass through opening  50 . The rib  20  is of a sufficiently small enough size to pass through the opening  50  when sufficient pressure is applied to the rib  20  to compress the rib  20  to a size sufficient to pass through the opening  50 . Conversely, the rib  20  is also sized sufficiently large enough to prevent passage of the push pin  5  out of the opening  50  and/or the opening  40  without application of a force sufficient to pull push pin  5  free by compression of the rib  20 . This process may be repeated with additional push pins if necessary to fix the film  35  into a desired position over the surface  55  of the vehicle interior. 
       FIG. 3  is a photograph of an example push pin. The example push pin is similar to the push pin  5  illustrated in  FIGS. 1 and 2  except that the example push pin comprises two ribs spaced apart from each other along the profile of the pin tip. This example push pin was molded as one piece from a compressible styrene-butadiene rubber. As discussed above, the push pins described herein may comprise any multiple of ribs of any size and shape. The ribs may be spaced apart on the pin tip as desired. 
       FIG. 4  is a photograph of multiple example push pins used to hold a film on top of a surface of the interior of a vehicle. As described in  FIG. 2 , the push pins have been inserted through openings in the film and then into openings within the surface of the interior of the vehicle. In this specific photograph, the openings are the air conditioning vents of the interior of the vehicle. The push pin ribs are compressible and are able to slide into the air conditioning vents with sufficient applied force. The push pin is then able to hold the film into a desired position as illustrated in the photograph. The push pins may be removed if a sufficient force is applied by pulling the head or other graspable portion of the push pin to compress the ribs to a degree that the push pin is able to be pulled out of the air conditioning vent. The push pin illustrated by the photograph of  FIG. 4  was machined from a piece of compressible polyethylene foam. 
     The push pin may be made from any compressible material. General examples of compressible materials include, but are not limited to, elastomeric materials, foamed materials, and the like. Specific examples of materials include polyethylene foam, polypropylene foam, polychloroprene foam, polyimide foam, polystyrene foam, polyurethane foam, polyvinylchloride foam, silicone foam, styrene-butadiene-styrene block copolymer (hereafter “SBS”) rubber, styrene-butadiene rubber (hereafter “SBR”), natural polyisoprene, synthetic polyisoprene, polybutadiene rubber, chloroprene rubber, butyl rubber, nitrile rubber, ethylene propylene rubber, ethylene propylene diene rubber, epichlorohydrin rubber, polyacrylic rubber, silicone rubber, fluorosilicone rubber, fluoroelastomers, perfluoroelastomers, polyether block amides, chlorosulfonated polyethylene, ethylene-vinyl acetate, or any combination thereof. In some alternative examples where the push pin is comprised of discrete components assembled to collectively form the push pin, all of the discrete components may be made from the same or different compressible materials, or only the rib(s) of the push pin may be made of compressible materials. If only the rib(s) of the push pin comprise compressible materials, the remaining materials (e.g., the head, the pin tip, or the holster discussed below) may be made from non-compressible materials such as hard plastics, metals, wood, composites thereof, or any combination thereof. 
     The push pin may be molded, machined, or otherwise provided as one continuous piece. For example, the push pin of  FIG. 3  was injection molded, and the flash from the molding process is still visible on the underside of the head. As another example, the push pins of  FIG. 4  were machined from a piece of foam into the desired shape of the push pin. The push pin may be manufactured by any sufficient process, and one of ordinary skill in the art, with the benefit of this disclosure, will be able to manufacture a push pin as described herein. In alternative embodiments, the push pin may not comprise one piece and may be assembled from separate components that collectively comprise the push pin. These discrete components may be molded, machined, or otherwise provided from any suitable manufacturing process. Assembly of the discrete components may involve coupling the components together via threaded connections, adhesives, latches, or any other such means as would be readily apparent to one of ordinary skill in the art. The discrete components may be interchangeable and capable of being switched with alternative components. Alternatively, the discrete components may be permanently attached to one another precluding separation of the individual components of the push pin. 
       FIG. 5  illustrates an isometric view of another embodiment of a push pin. Push pin  100  comprises interchangeable components. Push pin  100  comprises a pin tip  110 . The pin tip  110  is a separate component from the head  115 ′ and rib  120 ′. If a different head is preferred head  115 ′ may be uncoupled from pin tip  110 , and then head  115 ″ may be coupled to pin tip  110 . For example, if a different size or shaped head is preferred, the head may be exchanged with one better suited for a particular application. The heads  115 ′ and  115 ″ comprise a commonly-sized coupling connection  125  (e.g., a commonly-sized threaded connection) that fits each head  115 ′ and  115 ″. The use of a commonly-sized coupling connection  125  allows for multiple heads of different sizes, shapes, and materials to interchange with a shared pin tip  110 . Further, it allows for a quick and easy exchange of one head for another without the need to adapt the coupling connection. Similarly, the rib  120 ′ may be interchanged with the rib  120 ″. The interior diameters of rib  120 ′ and rib  120 ″ are sized the same which allows for multiple ribs to fit over the pin tip  110  and be interchanged with a shared pin tip  110 . The ribs may vary in outer diameter, outer shape, or outer materials and may comprise any type of coupling connection (e.g., a threaded connection) that may couple the ribs to the pin tip  110 . The coupling connection materials may comprise different materials than the rest of the pin tip  110 , heads  115 ′ and  115 ″, or ribs  120 ′ and  120 ″. For example, the coupling connection materials may be metal or other such materials embedded in or otherwise attached to the compressible materials forming the push pin  100  and its individual components. 
       FIG. 6  illustrates a cross-sectional view of another embodiment of a push pin. The push pin  200  is similar to the push pin  5  illustrated in  FIGS. 1 and 2 . The push pin  200  comprises a pin tip  210 , a head  215 , and ribs  220 . Push pin  200  additionally comprises an adhesive layer  230  adjacent to the head  215  and layered upon the head  215 . Adhesive layer  230  may cover all of or just a portion of the head  215 . The adhesive layer  230  may be used to adhere a material to the push pin  200 . In the illustrated example, push pin  200  is used to adhere a film  240  to the push pin  200 . When desired for use, the push pin  200  may be inserted into an opening  50  in a surface  55  of a vehicle interior. The pin tip  210  may be inserted into the opening  50  past the portion of pin tip  210  comprising one or more ribs  220  such that the ribs  220  are inserted into and through the opening  50 . In the illustrated example, the push pin  200  is inserted into the opening  50  to a sufficient depth that the underside  245  of head  215  contacts the surface  55 . The opening  50  may be any opening in a surface  55  of a vehicle and is not limited to openings in the vehicle interior. An example of an opening  50  is an air conditioning vent. The push pin  200  is sized such that the pin tip  210  may easily pass through the opening  50 , but the head  215  is too large in diameter to pass through the opening  50 . Ribs  220  are of a sufficiently small enough size to pass through the opening  50  when sufficient pressure is applied to pin tip  210  to compress the ribs  220 . Conversely, the ribs  220  are of a sufficiently large enough size to prevent passage of the push pin  200  out of the opening  50  without application of a force sufficient to pull the push pin  200  free by compressing the ribs  220 . A film  240  may then contact adhesive layer  230  to position film  240  on the interior of the vehicle as desired. In some embodiments, a liner or other covering may be placed on adhesive layer  230  to prevent premature contact with adhesive layer  230 . The liner may be removed prior to use. 
     The adhesive in the adhesive layer  230  may be any adhesive sufficient for a desired use. Examples may include, but are not limited to, waterborne adhesives, solventborne adhesives, hot melt adhesives, acrylic adhesives, natural and/or synthetic rubber adhesives, silicone adhesives, or any combination thereof. It is to be understood that the adhesive should be chosen such that it does not negatively interfere with the compressible material used to form push pin  200  or the material of the component to which the adhesive layer  230  is to attach the push pin  200 . The push pin  200  may be used in embodiments where it may be more desirable to adhere a material to the push pin  200  instead of pushing the push pin  200  through a hole or opening in the material. However, push pin  200  is still mountable inside the vehicle interior without the use of adhesives or clamping, and the pin tip  210  and ribs  220  portions of the push pin  200  do not comprise adhesives or clamping means. The adhesive layer  230  is used only to adhere a material to the mounted push pin  200 . If not already mounted to a surface, the push pin  200  may then be mounted to the surface. 
       FIG. 7  illustrates an isometric view of another embodiment of a push pin. Push pin  300  comprises a pin tip  310  and at least one rib  315 ; however, the head has been replaced with a holster  320 . Holster  320  may be used to hold accessories. Examples of accessories may include, but are not limited to, cell phones, music players/storage systems, air fresheners, GPS systems, lights, trash/storage containers, fans, and the like. Push pin  300  functions identically to the other push pin embodiments described herein and may be inserted into any opening in a surface of a vehicle interior. A chosen accessory may then be placed in the holster  320 . Holster  320  may be designed having any sufficient shape for holding a desired accessory. Push pin  300  may comprise holster  320  together with pin tip  310  and at least one rib  315  as one continuous piece; alternatively, push pin  300  may comprise separate components which collectively provide push pin  300 . For example, push pin  300  may comprise a holster  320  that is interchangeable with other holsters  320  having different sizes and/or shapes. The interchangeable holsters  320  may have a commonly-sized coupling connection allowing the interchangeable holsters  320  to share a pin tip  310 . The holsters  320  may be switched as desired to hold different accessories. 
     In all embodiments, the push pin may be removed by applying a sufficient force to the head or holster to compress the at least one rib such that the rib may slide out of any opening in a surface in which the push pin was inserted.
