Title: Fastening device for a shower curtain

Description:
FIELD OF THE INVENTION 
     The present invention relates to a fastening device. More specifically, the present invention teaches and discloses a shower curtain connector that has, at its first end, a fastener to receive an aperture of a sheet material, preferably a shower curtain and, at its second end, a coupling means such as a curved hook that can hang on a shower curtain rod. The fastening device can be sized and colored as desired and can be made from any material that is flexible, springy yet sturdy and afford a degree of rigidity. Thus, it can be made from any plastic, resin, metal, synthetic or natural material, and/or part plastic and part metal. Therefore, it can withstand repeated use by a user using it on a daily basis without breaking or cracking and at the same time it is sturdy enough that it is capable of holding up a sheet material such as shower curtain and to block water from spilling outside of a bathtub. More particularly, the fastening device of the present invention has two ends, a coupling means and an attachment means. The first end is an attachment means that has a bridge connecting two elongated members, one member has an extending member from its interior surface, wherein the second elongated member has a corresponding recess disposed on its interior surface, whereby when the attachment means is in use, the extending member is matingly fitted with the recess. The bridge is further comprised of a recess to receive a second end of a coupling means. The coupling means defines a receiving surface at a first portion thereof, and an extended second portion thereof. The receiving surface of the coupling means slidably couples to a substantially fixed object. The coupling means can be in any shape made from any material in any color and it can optionally have bearings and/or beads in any shape made from any material to facilitate the sliding motion on a substantially fixed object, namely a rod. The extended second portion of the coupling means is matingly fitted with the recess disposed on the bridge connecting two elongated members to form the fastening device as claimed and disclosed. The attachment means of the shower curtain connector can be rotatable or optionally stationary. Consequently, when a user is hanging up a shower curtain, he or she no longer has to hover over the bathtub and struggle for a secure non-slippery surface in the bathtub for a strong foothold to try to secure the shower curtain rings first to the shower curtain rod and then try to connect the shower curtain to the shower curtain rings. A user can now leisurely connect the fastening device to a sheet of material, i.e., a shower curtain, then walk over to the bathtub and hang up the shower curtain as if hanging a hanger on a rod without risking standing on a small slippery surface. In addition, the fastening device of the present invention is safely secured to and rests on the shower curtain rod since the coupling means preferably has a U-shaped hook and thus, would not and cannot be easily removed from the rod. In addition, since the shower curtain is secured between the extending member that is matingly fitted with a recess, it is not likely that the shower curtain will become separated and/or loose from the fastening device after repeated use. 
     The fastening device may also have coupling means in various shapes and forms. For example, the coupling means can be in the shape of a circular ring, or an oval ring having a locking mechanism or in an “S” shape to facilitate easy assembling. The coupling means can also optionally have at least one bearing and/or beads in the shape of a circle and/or a rectangle opposite the receiving surface in order to facilitate movement of the fastening device on the rod. 
     Accordingly, the present invention can relate to a coupling device, connecting a sheet material to a substantially fixed object such as a rod, and it can be made from any material that is flexible yet sturdy with a degree of rigidity. Optionally, it can have bearings and/or beads to facilitate movement of the coupling means on the rod. The coupling means can be any color and can optionally have at least one decorative ornamentation in order to match the decor of its environment. 
     Various documents may be mentioned in this text; and, each herein mentioned document and each document cited or referenced in each herein mentioned document, is hereby incorporated herein by reference. 
     BACKGROUND OF THE INVENTION 
     Shower curtain rings have been in existence for a long time and they come in all shapes and sizes and are made from all different kinds of material. Ultimately, all of these shower curtain rings serve the same purpose of causing the shower curtain to remain in an upright and vertical position while in use, thus keeping water confined to the interior of the bathtub and providing a vertical wall between a bathtub and the rest of the bathroom environment. Over the years, various shower curtain rings having different shapes and made from different materials have been introduced into the market, but no matter what the new design is, the “newly-developed” shower curtain rings always require a user to assemble the shower curtain by either standing within the bathtub or on the edge of the bathtub, hovering over the edge of the bathtub to first line up the apertures in the shower curtain, then threading the shower curtain rings through the apertures, and then securing the shower curtain rings holding the shower curtain to the shower curtain rod. In short, whenever a user is setting up a shower curtain over a bathtub, he or she inevitably, through conventional shower curtain rings, must complete hanging the shower curtain by attaching the assembly of the shower curtain rings first to the shower curtain then to the rod. Contrary to the known conventional shower curtain rings, the fastening device of the present invention can be utilized anywhere without requiring the user to stand over the bathtub when installing a shower curtain. Thus, a user can leisurely attach each individual fastening device first to a sheet material, such as a shower curtain, by placing each of the apertures of the shower curtain between the extending member and the recess of the attachment means and locking the sheet material in place by forcing the extending member into the recess. This is repeated until all the apertures of the shower curtain are connected to the fastening device of the present invention. Once the fastening devices are secured to the shower curtain, a user can assemble the shower curtain by hanging each of the fastening devices to a rod. Furthermore, the attachment means of the present invention is optionally rotatable, thus, during shipping the coupling means parallel the attachment means, and when in use the coupling means are perpendicular to the attachment means. Moreover, the coupling means end of the fastening device is capable of independent movement from the attachment means. 
     With respect to shower curtain rings, reference is made to the following: 
     Cheng, U.S. Pat. No. 6,189,597 B1 issued Feb. 20, 2001, relates to a hanger ring assembly for a curtain. More specifically, it relates to a curtain with a hanger ring assembly for mounting onto a supporting rod which includes a sheet material and a plurality of hanger units. The sheet material has a plurality of hanger openings formed along a top edge, and a plurality of edge gap each extending from the top edge to an upper portion of the respective hanger opening. Each of the opening portions defines a section of connecting tab adjacent to the respective edge gap. Each of the hanger units includes a hanger ring which has a ring slit separating two ends thereof and defines a section of ring tab adjacent to the ring slit. Each of the hanger rings is attached to one side of the respective opening portion and coaxially extended around the respective hanger opening with the ring slit of the respective hanger ring staggering with the edge gap of the respective opening portion. The connecting tabs of the opening portions of the sheet material are detachably overlapped with the ring tabs of the hanger rings respectively. Each of the hanger units further includes a connecting device for selectively connecting each of the ring tabs with the respective connecting tabs. Thus, the hanger ring assembly according to Cheng attached a curtain directly to a supporting rod without any connectors. 
     Klotz, U.S. Pat. No. 6,067,672 issued May 30, 2000, relates to a shower curtain closure assembly for semi-permanent securement of an edge of a curtain to a wall of a shower enclosure. The closure assembly includes a clamping structure which comprises a mounting bar for permanent securement to a wall of a shower enclosure. The mounting bar includes a wall attachment surface for attachment to a wall of a shower enclosure and a first clamping surface. The mounting bar further includes a plurality of first fastener receiving holes. Supported on the mounting bar is an adjustable clamp including a second clamping surface which is disposed adjacent to the first clamping surface. The adjustable clamp includes a plurality of second fastener receiving holes. The first fastener receiving holes of the mounting bar are aligned with the second fastener receiving holes of the adjustable clamp. A plurality of threaded fasteners are disposed such that a threaded fastener engages each of the aligned first and second holes for securing the adjustable clamp to the mounting bar. A first curtain edge is disposed between the first and second clamping surfaces. The fasteners may be selectively tightened from a first position where the adjustable clamp is loosely secured to the first clamping surface such that the first curtain edge may be easily disposed between the first and second clamping surfaces, to a second waterproof position where the fastener is under tension and applies a compressive clamping force on the first and second clamping surfaces as well as the intervening first curtain edge. The compressive clamping applied to the first curtain edge by the fastener in the second position exceeds the shear strength of the curtain such that a force which exceeds the shear strength of the curtain applied to the curtain first edge will result in the tearing of the curtain before the release of the edge of the curtain from the position between the first and second clamping surfaces.

A pull cord system is incorporated into a conventional shower curtain assembly so that the curtain can be opened or closed with minimum stress on the curtain material. 
     Each of these patents provides a method of attaching a shower curtain to a rod or securing the shower curtain to the bathtub or inner wall of the bathtub. However, none of these patents claims or discloses, teaches or suggests an apparatus capable of attaching the shower curtain to a rod without having the user have to assemble the connection between the shower curtain and the shower curtain ring and then the shower curtain ring to the shower curtain rod all in one setting while standing on the edge of the bathtub. 
     Thus, it is believed that heretofore the present invention has not been taught or suggested. 
     OBJECTS AND SUMMARY OF THE INVENTION 
     It is therefore an object of the invention to provide a novel fastening device. 
     It is also an object of the invention to provide a fastening device which is suitable to connect to a sheet material and couple the sheet material to a substantially fixed object. 
     It is yet a further object of the invention to provide an apparatus for coupling to an object, comprising coupling means for slidably coupling the apparatus to a substantially fixed object. 
     It is still yet another object of the invention to provide a connector that can fasten a sheet material at one end and slidably couple to a substantially fixed object. 
     It is still further yet an object of the invention to provide a fastening device that can be used to first attach itself to a sheet material, then simultaneously couple to a shower curtain rod so, a user can assemble the sheet material, preferably a shower curtain, to a shower curtain rod without standing on the edge of the bathtub when connecting the shower curtain to the rod through a shower curtain ring. 
     Thus, the present invention provides a fastening device comprised of an attachment means to attach itself to a sheet material and a coupling means for slidably coupling itself and the sheet material to a fixed object. The fastening device can be made from any material such as plastic, or resin from blow-molding or injection molding; alternatively, it can be made by any metal or a combination of plastic, or resin with metal or any synthetic or any artificial material. The fastening device is comprised of two parts. The first part is comprised of an attachment means having a bridge connecting between two elongated members, the first elongated member has an extending member and the second elongated member has a correspondingly recess that, when the attachment means of the fastening device is in use, the extending member is matingly engaged with the recess. The second part of the fastening device is comprised of a coupling means to slidably couple to a substantially fixed object. The coupling means can be shaped as a half-oval so as to securely attach itself to a substantially fixed object. It can be S-shaped. Alternatively, the coupling means can be shaped as a circle or an oval ring made from two halves connected at one end by a hinge, and at the other end by a locking mechanism that is generally comprised of two engaging parts, one has a protrusion and the other, a corresponding recess to receive the protrusion. In addition, the circular and/or the oval shape coupling means also have an extended second portion having a narrowed portion and a slightly enlarged bulbous head to matingly engage with the recess on the attachment means. Furthermore, the coupling means may optionally have at least one ball bearing and/or beads in any shape disposed on the outer surface of the coupling means preferably opposite the receiving surface of the coupling means to facilitate the movement of coupling means on the substantially fixed object. Furthermore, the coupling means may also have a different shape or form and be made from any material and in any color in order to match with the decor of the environment it is in. 
     In a preferred embodiment of the invention, the coupling means will be shaped as half of an oval having its center of gravity positioned at the quarter point of the oval and the weight of the sheet material will force the coupling means to slidably couple to a substantially fixed object and maintain its balance. 
     In another embodiment, the coupling means is in an “S” shape and optionally having at least one bead disposed on the opposite surface of the receiving surface of the coupling means to facilitate smooth movement of the fastening device to the substantially fixed object. 
     In yet another embodiment, the coupling means is in a circular and/or an oval shape that is formed by connecting two half circles and/or two half ovals connected by a hinge on one side and a locking mechanism on another. The locking mechanism is generally comprised of two engaging surfaces, one having a protrusion and the other having a recess to receive the protrusion. The exterior surface of the receiving surface of the coupling means optionally has beads disposed on it in order to facilitate the sliding motion of the coupling means, hence the fastening device with a sheet material, preferably a shower curtain, to slide easily on a substantially fixed object, preferably a shower curtain rod. 
     In a preferred embodiment, the attachment means is attached to a coupling means through a recess disposed on the bridge of the attachment means and this enables the attachment means to be rotatably attached to the coupling means. Thus, in addition to connecting the sheet material, preferably a shower curtain, to a substantially fixed object, it can also minimize shelf space when packaged for sale by rotating the attachment means to be on the same plane with the coupling means.

The second end of the second elongated member has an exterior surface and an interior surface and the interior surface defines a corresponding recess  20  to receive the extending member  16 . Therefore, when the fastening device of the present invention is in use, the extending member  16  is matingly engaged with the recess  20  to provide a tight fit. 
     FIG. 11 shows a second embodiment of the present invention whereby the coupling means  33  is S-shaped and the exterior of the receiving surface optionally has circular beads  41 . The circular beads disposed on the opposite side of the receiving surface facilitate the movement of the fastening device on any object it couples to. The coupling means  33  has an extended second portion  31  having a bulbous head  30  that pierces the recess  21  disposed on bridge  15  to connect with attachment means  11  via sleeve  17  and recess  21 . The attachment means has extending member  16  and bulbous head  19  that is slightly larger in diameter. 
     FIG. 12 shows a third embodiment of the present invention whereby the coupling means  43  is S-shaped and the exterior of the receiving surface  27  has rectangular beads  42  disposed on it in order to facilitate movement of the fastening device when coupled to a substantially fixed object. The coupling means  43  has an extended second portion  31  that facilitates the engagement of the attachment means to the coupling means. 
     FIGS. 13 and 14 show a fourth embodiment of the present invention wherein the coupling means  53  is S-shaped and has an extended second portion  31  having a bulbous head  30  that engages with the attachment means  11  through sleeve  17  and recess  21  disposed on the bridge  15 . Extending from both edges of the bridge  15  are two extending members each having a first end and a second end respectively. The second end of the first elongated member  12  has an extending member  16  and the second end of the second elongated member  18  has a recess  20  to receive a bulbous head  19  of the extending member thus, when the attachment means  11  is in use (as shown in FIG.  13 ), it can secure a sheet material between the extending member  16  and recess  20 . Additionally, the attachment means  11  is rotatably attached to the coupling means  53 . Therefore, when the fastening device is in transit (as shown in FIG.  14 ), the attachment means  11  parallels coupling means  53  and both are in the same plane, and when the fastening device is in use the attachment means  11  can be rotated so as to become perpendicular to the coupling means (as shown in FIG. 13) in order to receive a sheet material  22 . FIG. 13 shows the configuration of the attachment means  11  in use where the bulbous head  19  of the extending member  16  pierces, penetrates and protrudes through the recess  20  of the second end of the second elongated member. 
     FIGS. 15 and 16 show a fifth embodiment of the present invention wherein the coupling means  33  is S-shaped and has circular and/or round beads disposed on the opposite surface of the receiving surface of the coupling means  33 . Coupling means  33  has an extended second portion  31  and a bulbous head  30  that pierces recess  21  via sleeve  17 . The bulbous head  30  has a slightly bigger diameter than recess  21  in order to ensure that the coupling means  33  will stay locked into the recess  21  and also to ensure a permanent attachment to the attachment means  11 . The attachment means  11  is rotatably attached to the coupling means. A sheet material  22  is fastened to the attachment means  11  via pressing the extending member  16  towards recess  20  thus, FIG. 16 shows the configuration when the extending member  16  is lodged in recess  20 . 
     FIGS. 17 and 18 show a sixth embodiment of the present invention whereby the coupling means  63  is circular and made from two halves connected at one end by a hinge  46  and a locking mechanism  48  that has two engaging parts. The first engaging part  50  includes a protrusion and a second engaging part  49  defines a corresponding recess to receive the protrusion and the two engaging parts can be locked by a friction fit. Coupling means  63  in FIG. 17 shows the coupling means in a locked position and FIG. 18 shows it in an unlocked position. The coupling means  63  has an extended second portion  61  extending from coupling means  63  and the extended second portion  61  has a bulbous head  60  that secures the coupling means  63  to attachment means  11 . Attachment means  11  has extending member  16  and bulbous head  19  that is matingly fitted with recess  20 . 
     FIGS. 19 and 20 show a seventh embodiment of the present invention whereby the coupling means  73  is circular and has rectangular beads  42  disposed on the opposite surface of the receiving surface  47  to facilitate the movement of the fastening device when coupled on a substantially fixed object. The coupling means  73  is circular and is made by connecting two halves at one side by a hinge  46  and at the other by a locking mechanism  48 . FIG. 19 shows the coupling means in a locked position and FIG. 20 shows the coupling means in an unlocked position. Like FIGS. 17 and 18, the locking mechanism  48  has two engaging parts, a first engaging part has a protrusion  50  and a second engaging part has a recess  49  to receive the protrusion  50  so, when the two engaging parts are engaged with each other, the surface of the coupling means  73  is smooth and the locking mechanism  48  blends into the coupling means  73  so as to hide the locking mechanism or make the locking mechanism invisible. The coupling means  73  has an extended second portion  61  having a bulbous head  60  to secure itself to the attachment means  11 . The attachment means  11  is rotatable as can be seen in FIGS. 19 and 20. 
     FIGS. 21 and 22 show an eighth embodiment of the present invention wherein the coupling means  83  is circular and made from two halves connected by a hinge  46  on one side and by a locking mechanism  48  on the other side. There are circular beads  41  disposed on the opposite surface of the receiving surface  47  to facilitate movement of the fastening device  80  when coupled to a substantially fixed object. The coupling means  83  has an extended second portion  61  which pierces through bridge  15  by entering sleeve  17  and the extended second portion  61  has a bulbous head  60  that is slightly larger than the diameter of recess  21  so, when the extended second portion  61  enters the sleeve  17  and passes through recess  21 , it will be permanently lodged and would prevent the extended second portion  61  from re-exiting recess  21 . The attachment means  11  is fixed to the coupling means  83  and thus, not rotatable. The attachment means  11  has an extending member  16  having a bulbous head  19  which will be matingly fitted with recess  20 . 
     FIGS. 23 and 24 show a ninth embodiment of the present invention wherein the coupling means  83  is circular and has circular beads  41  disposed on the opposite surface of the receiving surface  47 . The circular beads  41  facilitate movement of the fastening device on a substantially fixed object when coupled. The coupling means  83  is made from two halves connected at one end by a hinge  46  and at the other end by a locking mechanism  48  which includes two engaging parts. Engaging part  50  has a protrusion and engaging part  49  has a recess to receive the protrusion and so when engaging part  50  locks with engaging part  49  by a friction fit, the position of the lock becomes invisible thus to create an appearance of a continuous circle. The attachment means  11  is attached to the coupling means  83  through the extended second portion  61  having a bulbous head  60 . The attachment means further comprises a fastening device to receive and fasten a sheet material to the attachment means  11  by the extending member  16  piercing the sheet material and be matingly engaged with a recess  20  that has a diameter slightly smaller than the bulbous head  19  disposed at the end of the extending member  16 , in order to create a snug fit and to prevent the sheet material from disengaging from the attachment means  11 . The attachment means  11  is rotatably connected to coupling means  83 . FIG. 24 shows a rotated attachment means  11  from the attachment means  11  in FIG.  23 . 
     FIGS. 25 and 26 show a tenth embodiment of the present invention wherein the coupling means  93  is oval-shaped and is made from two half ovals connected at one end by a hinge  46  and at the other by a locking mechanism  48  having two separate, but corresponding engaging parts. Thus when the two corresponding engaging parts  49  and  50  respectively are engaged with each other, it would provide the appearance of a continuous one piece oval coupling means without the locking mechanism being visible. The engaging part has a protrusion  50  and a corresponding recess  49  to receive the protrusion  50 . FIG. 26 shows the coupling means  93  at an open position. The coupling means  93  is further comprised of an extended second portion  71  having a bulbous head  70  that is fixably engaged with the attachment means  11  through sleeve  17  disposed on bridge  15  and above recess  20 . Once the coupling means  93  is properly engaged with attachment means  11 , the bulbous head  70  will prevent the extended second portion  71  from disengaging itself from the attachment means  11 . The attachment means  11  is attached to the coupling means  93  permanently and not rotatably. The attachment means  11  has a bridge  15  having two elongated members connected to either edge of the bridge  15 . Above the bridge  15  is a sleeve  17  to receive the extended second portion  71  and a recess  21  to receive the extended second portion  71 . The two elongated members have their respective first ends  13  and  14  and their respective second ends  12  and  18 . These elongated members face each other and the interior surface of the second end of elongated member  12  has an extending member  16  having a bulbous head  19  and the interior surface of the second end of elongated member  18  has a recess  20  that can be correspondingly engaged to the extending member  16 . Accordingly, a sheet material can be fastened by the attachment means by positioning the sheet material between the extending member  16  and recess  20 , then put pressure on extending member  16  and bring it toward recess  20  in order to lock the sheet material in place. In application of the present invention, a user can first place the sheet material between the extending member  16  and recess  20  to bring closure to the extending member and recess ensemble. Then the user can open the locking system  48  and wrap the two halves with the coupling means  93  around a substantially fixed object and then close the locking mechanism as shown in FIG.  25 . 
     FIGS. 27 and 28 show an eleventh embodiment of the present invention fastening device with a movable and rotatable attachment means  11 . The coupling means  103  is oval-shaped having rectangular beads disposed on the opposite surface of the receiving surface  57  of the oval-shaped coupling means  103 . These rectangular beads can be in any shape desired and can be made from any material. These beads  42  facilitate the movement of the fastening device when it is coupled with a substantially fixed object. The coupling means  103  is made from two half ovals joined at one end by a hinge  46  and at the other end a locking mechanism having two corresponding engaging parts  49  and  50  respectively. The coupling means  103  has an extended second portion  71  having a bulbous head  70  that is slightly larger than recess  21  so that the extended second portion  71  can enter and go through recess  21  but cannot back out once the bulbous head  70  of the extended second portion  70  goes through recess  21 . Thus, the attachment means  11  cannot be easily separated from coupling means  103 . The attachment means  11  is rotatably attached to the coupling means  103 . Thus, when the fastening device of the present invention is in use, the attachment means  11  is rotated 90 degrees as shown in FIG.  28 . The recess  20  of the attachment means  11  may be a recess or it may be a through hole. FIG. 28 also shows the coupling means  103  in an open position ready to couple with a substantially fixed object. 
     FIGS. 29 and 30 show a twelfth embodiment of the present invention with an oval-shaped coupling means  113  having circular beads  41  disposed on the opposite surface of receiving surface  57 . The circular beads  41  can also be made in rectangular, in triangular or in any shape desired, such as little flowers or snowflakes or animations of any cartoon, fictitious or real-life persons, to match the sheet material to which it is attached or to match and complement the decor. The coupling means  113  is made from two half ovals connected at one end by a hinge  46  and at the other end by a locking mechanism  48 . The locking mechanism, in addition to the corresponding engaging means thus far described, can also be any conventional locking mechanism such as a male adaptor and a female receiver, a friction lock, a pressure lock or any other lock that can join two pieces together. The coupling means  113  is provided with an extended second portion  81  having a bulbous head  80  that is pushed through recess  21  and lodged in recess  21 . The attachment means  11  is not rotatably attached to the coupling means  113 . FIG. 30 shows the coupling means in an open position where the locking mechanism is disengaged. The attachment means  11  is as previously described. 
     FIGS. 31 and 32 show a thirteenth embodiment of the present invention with an oval-shaped coupling means  113  having circular beads  41  disposed on the opposite surface of the receiving surface  57 . The beads  41  can be of any shape and can be made from any material. The beads  41  facilitate the movement of the fastening device of the present invention when the fastening device is slidably coupled to a substantially fixed object. The coupling means  113  is made from two half ovals joined at one end by a hinge  46  and at the other end by a locking mechanism  48 . The coupling means  113  has an extended second portion  81  opposite the receiving surface  57  so as to attach itself to an attachment means. The extended second portion  81  is positioned such that it divides the coupling means  113  into two equal halves so as to ensure the fastening device will remain upright. The attachment means  11  is rotatably attached to the coupling means  113 . Thus, FIG. 32 illustrates the attachment means  11  when the fastening device is in use and it also illustrates the coupling means  113  in an open position. Accordingly, FIGS. 31 and 32 show attachment means  11  is freely rotatable with respect to the coupling means and that the attachment means  11  is at a different rotation when it is in use than during shipping, where it will be rotated 90 degrees in order to reduce and minimize space required. 
     While the invention has been described with respect to use as a connector and/or a fastening device to connect between a sheet material and a substantially fixed object, it is to be understood the invention can be used to connect between two sheet materials or any two objects. It is further to be understood that the fastening device of the present invention can be made from any method, such as injection molding, blow-molding or any conventional method and can be made from any material synthetic or natural in any colors. The material and object to be fastened and connected by the present invention are not necessarily limitations of the invention. 
     It is to be further understood that any utilitarian description herein of any component of the fastening device of the present invention, for example, the coupling means, the beads or any feature thereon, or the attachment means, or any feature, i.e. any feature thereon, is not to be construed as a statement that the appearance of any component of the invention is functional in nature or dictated by function. Surface ornamentation or configuration of the fastening device or any components thereof, for example, the exterior of the fastening device, such as the coupling means or the attachment means or any portion thereof, are attributable to ornamental considerations. 
     The coupling means  23  and the bridge  15  are preferably formed from a substantially rigid material, including but not limited to metal, glass, plastics and thermoplastics, either opaque or transparent, preferably polypropylene and ceramics. The coupling means and the attachment means can be sculptured and/or molded, i.e., blow-molded in any form or shape desired, specifically the attachment means can be made from more flexible material that is resilient and not easily breakable and can withstand repeated use and application and also would not break, rust or change shape due to temperature and humidity changes. The fastening device should also be made from material that is childproof and when broken would not be injurious to animals or users and can easily take on any color in order to match the décor. 
     As can be further appreciated from the foregoing description and the illustrated embodiments, the fastening device of the present invention does not necessarily require a closed ring for the coupling means and the attachment means does not necessarily need to be rotatably attached to the coupling means or that the attachment means is necessarily a separate component from the coupling means. Thus the attachment means and the coupling means can be molded from the same mold as one piece, they can also optionally be made in two pieces and put together by conventional method or by forcing the extended second portion through the recess on the bridge. They could be made from metal and the elongated member processed by annealing and/or heat treatment in order to impute springy-like feeling to facilitate the engagement of the extending member and its corresponding recess or, they can be made from any material in any shape or form having any decoration as to the client&#39;s and/or customer&#39;s liking. 
     Having thus described in detail the preferred embodiments of the present invention, it is to be understood that the invention defined by the appended claims is not to be limited by particular details set forth in the above description, as many apparent variations thereof are possible without departing from the spirit or scope of the present invention.
