This application is a Continuation of my co-pending U.S. patent application Ser. No. 15/528,811, filed on Oct. 30, 2014, which claims priority to U.S. Provisional Patent Application No. 61/962,086, filed Oct. 31, 2013, whose contents are incorporated by reference in their entirety.
FIELD OF THE INVENTIONThe present invention relates to a new and improved device and method for holding or securing an article against a surface using a suction cup connected to a bi-stable snap action ribbon spring. The field of invention covers a securing device comprised of a bi-stable snap action ribbon spring connected to a suction cup which may be used to secure or hold an article against a surface. More specifically, the present invention provides a unique device and method for holding or securing an article against a vertical or horizontal or slanted surface using a bi-stable snap action ribbon spring connected to a suction cup. The field of invention further covers securing or holding an article against any conceivable vertical, horizontal, or slanted surface where the article includes any conceivable object capable of being held or secured to a surface using a bi-stable snap action ribbon spring connected to a suction cup.
In some embodiments, the surface may be the vertical wall inside of a bathroom, such as perhaps the wall of a shower stall, or the surface might be a horizontal surface within a bathroom, such as perhaps the horizontal ledge of a bathtub, and the article may be a hollow container containing a liquid such as shampoo where the hollow container is secured against the vertical surface by use of a bi-stable snap action ribbon spring and where the bi-stable snap action ribbon spring is secured against the vertical surface by a suction cup connected to the bi-stable snap action ribbon spring. And in some embodiments, the article or hollow container that is secured to the vertical surface may be configured in such a method that the hollow container rests upon a horizontal surface. And in some embodiments, the article or hollow container that is held or secured to the vertical surface by the bi-stable snap action ribbon spring, connector, and suction cup, and configured to rest upon a horizontal surface, may be positioned in an orientation such as right-side-up or up-side-down. In some embodiments the article or hollow container may be positioned in an inverted or up-side-down orientation while held by the bi-stable snap action ribbon spring and while the connected suction cup is secured to a vertical surface so as to permit the hollow container to rest upon a horizontal surface allowing the liquid within the container to gravitate and accumulate towards the end of the container approximate to the opening nearby the vicinity where the liquid is dispensed from.
In some embodiments, the article or hollow container may be oriented right-side-up while secured to a vertical surface by use of a bi-stable snap action ribbon spring connected to a suction cup and configured in such a manner that the hollow container rests upon a horizontal surface to permit easy storage upon the horizontal surface. In some embodiments, the article or container may be oriented right-side-up while secured to a horizontal surface by use of a bi-stable snap action ribbon spring connected to a suction cup and configured in such a manner that the container rests upon a horizontal surface to permit convenient and reliable storage of the article or hollow container containing a liquid thereupon the horizontal surface thus preventing the article from being accidently knocked off of the horizontal surface resulting in unintended and wasteful drainage or spillage of liquid within the article or hollow container.
And in some embodiments, the bi-stable snap action ribbon spring connected to a suction cup may be secured to a vertical surface and configured to support an article by inserting the smaller width of that article through the center region of the bi-stable snap action ribbon spring within the stable coiled state so as to permit a second larger width of that article at an opposing article length to be supported upon the horizontal surface of the coiled spring due to the fact that the second larger width is greater than the coiled spring inner diameter of the center region thus not allowing the article to fall through the center region.
Applications of relevant use may include, but are not limited to: holding or securing a hollow container such as a shampoo bottle in an inverted up-side-down position against a tile bathroom vertical surface while the hollow container rests upon a horizontal surface; holding or securing a hollow container such as a shampoo bottle in a right-side-up orientation against a horizontal surface while the hollow container rests upon that horizontal surface; holding or securing a solid object such as a candle against a vertical surface while the candle rests upon a horizontal surface; holding or securing a solid object such as a candle against a horizontal surface while the candle rests upon that horizontal surface; or, securing a smart phone to a water bottle for easy consolidated storage of both items for use in a fitness center.
Furthermore, the securing device allows the user to store articles against a surface where the article has a large width and a small width across the length of that article and where the larger width is greater than the width of the coiled spring inner diameter to result in easy storage by inserting the article into the center region of the bi-stable snap action ribbon spring in the stable coiled state so as to allow the larger width of the article to rest upon the horizontal surface of the coiled spring.
SUMMARY OF THE INVENTIONThe present invention utilizes the bi-stable characteristics of a snap action ribbon spring together with the adhesion characteristics of a suction cup to create a self-latching, spring-loaded mechanism for securing an article to a surface. The new and improved device and method for holding or securing an article against a surface using a suction cup connected to a bi-stable snap action ribbon spring can be used in a vast array of practical every day applications, including, but not limited to, greatly simplifying the ease of draining a liquid from a hollow container in an effortless manner by the use of gravity by allowing the liquid within the hollow container to accumulate or settle towards the vicinity approximate to the opening where the liquid is dispensed from the hollow container. The present invention further utilizes the bi-stable characteristics of a snap action ribbon spring together with a suction cup to create a self-latching, spring-loaded mechanism that greatly simplifies the ease of storing articles against a vertical or horizontal or slanted surface to take advantage of additional storage space within various settings, including, but not limited to, household, academic, commercial, recreational, or industrial environments.
It is to be understood by one of ordinary skill in the art that the present discussion is a description of exemplary embodiments only, and is not intended as limiting the broader aspects of the present invention, which broader aspects are embodied in the exemplary constructions. Reference will now be made in detail to various embodiments of the invention. Each embodiment is provided by way of explanation of the invention, not limitation of the invention. In fact, it will be apparent to those skilled in the art that modifications and variations can be made in the invention without departing from the teaching and scope thereof, for instance, features illustrated or described as part of one embodiment to yield a still further embodiment derived from the teaching of the invention. Thus, it is intended that the invention cover such derivative modifications and variations to come within the scope of the invention embodiments described herein and their equivalents.
The suction cup snap-spring securing device of the present invention is comprised of a bi-stable snap action ribbon spring, a connector, and a suction cup. A “snap-spring”, or bi-stable snap action ribbon spring, and sometimes within the accompanying text is also termed as a ribbon, spring, or tape, as used in the present invention, is comprised of a longitudinal tape material. Preferred tape materials are metals although polymeric materials, composite materials, or any conceivable material suitable for the application may be used as well. In some embodiments, the bi-stable snap action ribbon spring can be equipped with a sheath, possibly made of a fabric or plastic material or a synthetic rubber material such as neoprene, or any other suitable material, which covers either a portion of, or the entire perimeter or outer surface of the bi-stable snap action ribbon spring. In some embodiments, the sheath is used to protect the user from possible sharp edges of the ribbon. In other cases, the sheath is used to protect the bi-stable snap action ribbon spring from corrosion, erosion, oxidation, or any other undesirable chemical reaction which may negatively impact its longevity or functionality.
A “suction cup”, as used in the present invention, is an object that uses negative fluid pressure of air or water to adhere to a surface and in the process creates a partial vacuum. The preferred type of suction cup is formed from a single piece of molded plastic or rubber material, or the like, and has a concave front face. It is to be noted that a suction cup used in the present invention is not limited to just plastic or rubber materials and any conceivable type of material may be used as long as the application of that material results in sufficient adhesion properties or characteristics to create a negative fluid pressure between the suction cup and the surface. In some embodiments, the suction cup has a neck extending outwardly from the rear face, opposite the concave front face. The neck can be located at the geometric center of the rear face of the suction cup, however in other embodiments it can be offset from the geometric center of the rear face. In other embodiments, the suction cup does not have a neck extending outwardly from the rear face, opposite the concave front face.
The connector is the connecting link between the suction cup and the bi-stable snap action ribbon spring. Any conceivable way to connect the suction cup and the bi-stable snap action ribbon spring falls within the scope and spirit of the present invention. A connector is affixed to the suction cup and to the bi-stable snap action ribbon spring and may be permanently mounted or removable. In some non-limiting embodiments, the connector may be constructed of hard plastic or metal or any type of polymer or composite material sufficient to affix to the suction cup to the bi-stable snap action ribbon spring. In other embodiments the connector is affixed to the neck of the suction cup. In other embodiments the connector may be mounted directly to the rear face of the suction cup.
A connector may also seamlessly adhere the bi-stable snap action ribbon spring to the suction cup in a manner that connects the bi-stable snap action ribbon spring to the suction cup. In some embodiments, the connector may comprise an adhesive material. The adhesive material may be any conceivable substance used for connecting the suction cup to the bi-stable snap action ribbon spring, including, but not limited to glue, fixative, cement, epoxy, a polymer or the like. The adhesive connector may also include affixing the suction cup to the bi-stable snap action ribbon spring by way of any conceivable heat treatment process that results in the bi-stable snap action ribbon spring being affixed to the suction cup. For example, one version of an adhesive connector may be realized by heat treatment, such as melting or softening, of at least a portion of the rear face or neck of the suction cup so that the bi-stable snap action ribbon spring is affixed to the suction cup.
In other embodiments, if the bi-stable snap action ribbon spring is equipped with a sheath covering at least a portion of the longitudinal tape, one version of an adhesive connector may be realized by heat treatment, such as melting or softening, of at least a portion of the sheath so that the bi-stable snap action ribbon spring is affixed to the suction cup. In other embodiments, an adhesive connector may be realized by heat treatment, such as melting or softening, of at least a portion of the bi-stable snap action ribbon spring so as to affix the bi-stable snap action ribbon to the suction cup. In other embodiments, if the bi-stable snap action ribbon spring is equipped with a sheath covering at least a portion of the longitudinal tape, one version of an adhesive connector is the sheath itself where the sheath that covers the bi-stable snap action ribbon spring also functions as the adhesive connector for securing the suction cup to the bi-stable snap action ribbon spring. For example, in one preferred but non-limiting embodiment, a bi-stable snap action ribbon spring contains a sheath comprised of a synthetic rubber such as neoprene or perhaps nitrile. Additionally, during the manufacture of the suction cup snap-spring securing device, a liquid synthetic rubber material may be applied to the outer surface of the bi-stable snap action ribbon spring, and then the suction cup may be affixed to the bi-stable snap action ribbon spring, and then when the synthetic rubber material of the sheath dries, the sheath essentially functions as an adhesive connection between the bi-stable snap action ribbon spring and the suction cup.
In some embodiments the connector may include a fastening member which joins the suction cup to the bi-stable snap action ribbon spring in a manner that allows for removal of the bi-stable snap action ribbon spring from the suction cup so as to permit the suction cup to remain in place.
A bi-stable snap action ribbon spring used according to the present invention is formed to be preferentially coiled along the tape longitudinal axis and has a preferred arcuate cross-section as viewed perpendicular to (or along) the longitudinal tape axis. A proposed explanation of the behavior of a bi-stable snap action ribbon spring is as follows:
1) When in a stable coiled state, the longitudinal stresses of the snap-spring (or ribbon) are generally relieved. The coiling of the ribbon also acts to flatten the arcuate cross-section, which strains the ribbon in the transverse direction.
2) By applying a longitudinal or tensional force, the ribbon can be progressively uncoiled which imparts longitudinal strain to the uncoiled portion of the ribbon. Also, as the ribbon is uncoiled, the transverse strain is relieved as the ribbon returns to its arcuate cross-section.
3) As the ribbon is fully uncoiled and extended into a linear state, the formation of the arcuate cross-section progresses along the full length of the ribbon.
4) When the ribbon is fully extended, a “snap” occurs as the transverse strain is relieved.
5) In the fully extended, stable linear state, the arcuate cross-section has a bending moment of inertia that resists the longitudinal coiling stresses developed as a result of the straightening or uncoiling of the ribbon. Thus the ribbon can remain in this linear configuration and resists re-coiling. The ribbon is also characterized as having a degree of column stiffness and therefor has a degree of bending resistance.
6) Affecting a “snap”, the linear ribbon is buckled and the arcuate cross-section is flattened in the buckled area, inducing transverse strain. The longitudinal stresses will induce a recoiling of the ribbon.
7) The recoiling of the ribbon initiates at the point of buckling and progresses down the length of the ribbon as the longitudinal coiling stresses are relieved and the transverse flattening stresses are accumulated.
8) When fully recoiled, the ribbon assumes the stable coiled state of step 1) above.
A bi-stable snap action ribbon spring, as used in the present invention, therefore has a stable “coiled” state and a stable “linear” state. While in a stable linear state, the application of a “snap” or buckling force will initiate a progressive self-coiling of the ribbon. If the ribbon is essentially unconstrained, the self-coiling will continue until the ribbon is fully coiled upon itself, or in the context of this invention, coiled around an article, such as around the outer circumference or perimeter of an article, such as either a hollow container or a solid object. While in this stable coiled state, the application of linear tension will force the coiled ribbon back to a stable linear state and by the application of a final “snap” the ribbon will remain in this linear configuration. A bi-stable snap action ribbon spring can therefore self-transition from a stable linear state to a stable coiled state upon the application of a “snap” or buckling force to the spring while in a stable linear state.
The suction cup connected to the bi-stable snap action ribbon spring holds or secures an article, including but not limited to hollow container or solid object, against a surface when in the stable “coiled” state. The surface may either be a vertical, horizontal, or slanted surface. Further, the surface may be fixed in a discrete location or arbitrary in a three dimensional space.
