Patent Application
20230031592
The present invention relates generally to devices for connecting drinkware to structures used in active outdoor sports, such as coolers. In particular, the invention uses the influence of a magnetic field to detachably couple drinkware, where a ferrous metal and a permanent magnet work together in complementary fashion to achieve a fast, but breakable connection, thereby stabilizing the drinkware for use during active outdoor sports.
The invention is also related to my co-pending applications entitled MAGNETIC DRINKWARE, Ser. No. 17/350,845, filed Jun. 17, 2021, and MAGNETIC ACCESSORY SURFACE MOUNT, Ser. No. 17/033,067, filed Sep. 25, 2020, which are hereby incorporated by reference.
In my co-pending application, U.S. Ser. No. 17/033,067, filed Sep. 25, 2020, and entitled Magnetic Accessory Surface Mount, I describe stand up paddle boards (SUPs) and other aquatic devices such as kayaks having magnets disposed as a surface mounted element on the deck of the SUP or kayak. The aforementioned co-pending application is hereby incorporated by reference.
As described in my prior application, for a wide variety of water and land vehicles, e.g., boats, automobiles, trucks, and all-terrain vehicles (ATVs), significant surrounding structures provide many opportunities to mount drink holders and other devices for holding a variety of accessories. For boats, drink holders can be hung on lifelines or mounted on wheel steering pedestals, or otherwise supported on vertical structures. Accessories like tools, flashlights, cameras, knives and other items can be stored in lazarettes, lockers, glove boxes and other structures which enclose the accessories.
Adventurers who use kayaks, canoes, rowboats and other open deck watercraft often store accessories in containers placed under seats or simply placed rested on the floor of the watercraft. Fetching the accessories does not present an appreciable problem: the adventurer can simply stop paddling or rowing, reach for the container, extract the accessory and use at will. Drinks kept in coolers, as well as accessories, are easily accessed because the adventurer uses the watercraft in a sitting position. Similarly, boats, ATVs and other land vehicles have bulk and vertical structures that keep accessories from being lost or ejected from movement of the boat or vehicle.
While itis advantageous to attach magnetically drinkware and other metallic items to a stand up paddleboard, or SUP, it is also desirable to have drinkware connected to other items used in active, outdoor sports, such as coolers.
In use, the cooler 10 sits on its flat bottom, on relatively flat ground, so that the top H is substantially horizontally disposed. Due to the strength of the cooler 10, an active sportsperson could sit on the top 14 as if it were a stool. Inside, the cooler 10 can contain ice and beverages. In certain designs of my inflatable watercraft, the deck of a kayak, for example, can be provided with a circular hole of approximately the same diameter as the cooler 10 so that the cooler 10 can be secured in position to provide the paddler with refreshment.
In use, a paddler, who may also be engaged in other aquatic sports such as fishing, will need a place to keep an article of drinkware, such as a stainless steel, insulated tumbler from falling into the water, or otherwise tipping over and potentially spilling contents into the watercraft. Such an event, while not dire, is at least inconvenient and messy. Heretofore, I am unaware of any coolers that come with drink holders, other than recessed cup holes to physically receive a cup or similar diameter. Such cup holes take up space and render portable coolers bulky and cumbersome. Moreover, most coolers simply do not have any means to support an article of drinkware. To the extent that a paddler places an article of drinkware on top of the cooler 10 of
A need exists for a simple, elegant solution for holding drinkware in sporting environments without allowing spillage, knock-down, or loss of the drinkware during active sporting activity. A further need exists for a solution that can be retrofit, or built in with original construction, but in either event inexpensive to manufacture, simple and cost effective.
In one aspect of the invention, an apparatus includes a generally flat patch having one of a permanent magnet and a ferrous metal plate embedded in a non-metallic material, and defining a flat upper surface and a flat lower surface, an adhesive film disposed on the lower flat surface of the non-metallic material, and a peel and stick protective sheet covering the adhesive film, and being removable to expose the adhesive film when the patch is ready to be attached to a non-metallic, generally flat surface.
Preferably, many different objects can be attracted to and thus detachably coupled to the patch, such as an article of drinkware including tumblers, thermos-shaped, bottle shaped or other common shaped cups used for refreshment during sporting activities. The container is preferably made of a non-ferrous material, and more preferably, the non-ferrous material is stainless steel. Stainless steel is a type of ferrous alloy, and while it does contain iron, which is ferrous, stainless steel objects are not magnetically attractive normally, given the other components that make up the alloy. For non-ferrous containers and articles, they must be fitted with a ferrous metal component to be attracted to the patch when the patch includes a permanent magnet. Likewise, if the patch includes a ferrous metal disc, the containers or other objects must be provided with a permanent magnet, such as one fitted into the bottom of a tumbler. Other object that could be detachably coupled to the patch include keys, cameras, pocket knives, and virtually anything having ferrous metal components that are desirably carried by active, outdoor sportspeople while engaged in fishing, paddling, boating, sailing and other outdoor sports.
The base of the container, which holds either a ferrous metal plate or a permanent magnet, can be made of plastic or ceramic material, or stamped or otherwise formed metal. For connecting to surfaces with embedded magnets, the base can be made of ferrous metal and can be simply attached to the patch which includes a magnet. Alternatively, the magnet can be contained in a ferrous metal base if polarities are aligned properly to be attracted, not repulsed, by the surface to which the container is desirably attached.
Preferably, the permanent magnet, whether in the patch or in the drinkware or other object, has a residual flux density (Br) of 14.5 to 14.8 KGs, a coercive force (Hc) of >11.2 KOe and a maximum energy product (BHmax) of 49.5 to 52 MGOe. Magnets of different properties can be used, so long as the goal of forming a detachable binding of accessories to the SUP is achieved. This means that the magnet should be strong enough to resist disruption and unintentional forces, such as when the drinkware encounters an onrush of water, a violet pitch, roll or yaw motion of a boat, land vehicle, bicycle or other active sport device. Forces of up to a few foot-pounds of energy should be required to remove the drinkware from a connected surface. This allows the user to reach down and grab a tumbler and remove it from the surface with relative ease, but at the same time, inadvertent and unintentional forces, which might wherein the magnet is a rare earth permanent magnet.
Preferably, the patch includes a permanent magnet encapsulated in plastic. The plastic encapsulation is then adhesively attached to a flat surface such as the top of a cooler, and then an article of drinkware, having a ferrous metal component, is magnetically coupled to the patch. Other objects having ferrous metal components can be attached to the patch as well.
In another aspect of the invention, the patch is adhered within a recess formed in a non-ferrous metal surface. In the case of a cooler, the plastic top can be molded with a recess the size and shape of the patch, which is then adhesively bonded to the cooler in the recess. Still further variations include embedding the magnet, or a metal plate, the plastic top of the cooler when molding the top. In terms of simplicity, the patch is preferably a retrofit on a flat top of a cooler, but the patch could include original equipment, such as a magnet molded into the plastic top, or fitted into a recess and bonded to the top in the recess. Further alternatives include retrofitting a ferrous metal disc on a cooler top, embedding the metal disc in a plastic top, or bonding the metal plate within a recess formed in the top.
While the invention is described with respect to a cooler of my particular design, virtually any flat, non-ferrous metal surfaces can be adapted to have a patch attached thereto, in order to magnetically couple an object to the flat surface. For example, a fiberglass boat deck or cockpit having a flat surface can have a patch adhesively bonded thereto by removing the peel and stick protective sheet removed, and then the adhesive-coated lower surface of the patch can be pressed onto the flat boat surface where desired. A particularly desirable application is the place the patch on the cooler of
In another aspect of the invention, two patches can be provided where neither the cooler, nor the drinkware, have magnetic elements. A first patch, having a magnet, can be attached to the flat top of the cooler, and the second patch, having the ferrous metal element, can be attached to the flat bottom of the article of drinkware. While it is preferred to have the magnet connected to the cooler, the positions could be reversed, so that the metal plate is attached to the cooler and the magnet is attached to the drinkware.
A further object of the invention is to provide a combination of a cooler and magnetic coupler so that any object having ferrous metal can be attached to the cooler. Similarly, other aspects of the invention include any combination of a first element, such as a boat, cooler, table, chair, etc., having a flat surface of non-ferrous material, and a second element, such as a cup, tumbler, pocket knife, fishing tackle bait can, or any suitable outdoor sporting equipment, where the two elements are detachably coupled to each other through magnetic force.
Other aspects of the invention will become apparent in view of the following detailed description and claims.

As seen in
A particularly preferred attachment is where the patch 26 is connected to the top 14 of a round cooler of my previous invention. An article of drinkware, such as tumbler 42, is detachably and magnetically coupled to the cooler so long as the tumbler has at least a ferrous metal component. In the illustrated embodiment, the tumbler 42 is of the type of double wall insulated stainless steel. Stainless steel does not normally have enough ferrous material to be attracted to magnets, so the tumbler 42 is provided with a metal plate 44 inside the base of the tumbler 42. The magnetic attraction between the magnet 30 and the ferrous metal plate 44 is what holds the tumbler 42 to the top 14 of the cooler.
All parts of the tumbler 42, except the magnet 30, are made of a non-ferrous material, and more preferably, stainless steel. Stainless steel is a type of ferrous alloy, and while it does contain iron, which is ferrous, stainless steel objects are not magnetically attractive normally, given the other components that make up the alloy. For purposes of this invention, “non-ferrous” thus means a material incapable of having a magnetic attraction capable of creating a holding force.
One type of stainless steel includes 11% chromium, which helps prevent iron (Fe) from becoming iron oxide (FeO2). Other types of stainless steel include the elements carbon, nitrogen, aluminum, silicon, sulfur, titanium, nickel, copper, selenium, niobium and molybdenum, among others. These stainless steels are sometimes designated by a three digit number. e.g., 304 stainless, which is a preferred material for the present invention.
As illustrated in
The invention takes on at least two significant forms. First, as a retrofit, the patch can be provided separate from any objects to be connected, so that the user can stick the patch 26 on any object the user selects. As an “after-market” item, the patch 26 can be provided with special art, logos, etc., as desired. As a slight variation, the patch can be built in and thus part of the original product design. Referring to
As with the other embodiment, the patch includes a magnet 52 encapsulated in a plastic shell 54 sized and shaped to fit into the recess 46, An adhesive layer 56 can be provided to adhere the shell 54 in the recess 46. A tumbler 58, made of double walled stainless steel, includes a ferrous metal plate 60 in a bottom portion of the tumbler 58. The tumbler 58 will be detachably coupled to the top 48 when the metal plate 60 is brought into the influence of the magnetic field created by the magnet 52, As a variation, the magnet 52 can be placed by itself, without a shell, into a recess, which is then filled with a thermoplastic resin which, when hardens, encases the magnet in the recess. In that case, an adhesive layer is not necessary, nor is an encapsulating shell. Further, an object to be detachably coupled to the magnet could be an object that is made of, or includes, ferrous metal so that an additional ferrous metal plate is not necessary.
A further aspect of the invention is that the positions of the magnet 52 and the metal plate 60 can be reversed, so that the metal plate 60 is part of the patch and the magnet 52 is part of the object to be attached to the patch. For example, the tumbler 58 could include the magnet 52, instead of the ferrous metal plate 60, and the patch could include the metal plate 60, instead of the magnet 52.
A still further aspect of the invention is to provide two patches, one carrying a magnet and the other carrying a ferrous metal plate. In that embodiment, a tumbler or other object having no ferrous metal and no magnet, can be connected to a cooler having no ferrous metal and no magnet, by taking a matched pair of patches one with the magnet and one with the metal plate, and attaching one to a cooler and the other to the bottom of an article of drinkware or other object. For example, a first patch can be connected adhesively to the deck of a boat, and a second patch can be connected to the bottom of a stainless steel tumbler having no ferrous elements. In this way, a custom tumbler can be made in situ, to be made magnetically coupled to any desired surface.
It is preferred to use the strongest magnets available for a limited amount of space. For that purpose, rare earth magnets, and particularly, neodymium magnets are preferred. These are permanent magnets made from an alloy of neodymium, iron and boron to form the Nd2Fe14 B tetragonal crystalline structure. These are commercially available from a variety of sources, and are widely considered the strongest type of permanent magnets available commercially.
As a further alternative, and in the simplest version of the present invention, a magnet can be adhesively bonded, or attached by fasteners or brackets, to the underside of a non-ferrous surface, such as the underside of a fiberglass deck or of a thin, hard plastic top of a cooler. It this form, an article of drinkware or other object containing a ferrous metal component, will be magnetically connected to the deck, cooler or other object without further need for a separate patch. In this embodiment, the magnet need not be encapsulated in plastic because it will be protected by the upper surface of the deck or cooler. As with the other embodiments, the magnet could be a metal plate or disc when the drinkware or other object includes a magnet.
The invention includes attaching a magnet using an adhesive layer with a peel and stick removable sheet, so that the patch, which contains the magnet, can be attached as a retrofit to existing structures. Any other suitable means to connect the patch to the structure can be used. For example, an adhesive can be applied to the patch, rather than using an adhesive layer and peel and stick sheet. Any suitable adhesives can be used, and can be applied as a spray-on, painted-on, dispensed through an applicator, or other suitable means. Mechanical fasteners may also be used, including screws, tacks, rivots, brackets, etc.
While the illustrated embodiments show attachments at upper surfaces of structures, such as the upper, or outer, surface of a cooler. Where a structure includes outer and inner surfaces, such as the deck of a boat, the patch can be attached to the inner surface, as a means of holding objects out of site and out of the way. In the simplest form, a magnet could be glued to the inner surface of a structure to magnetically hold items like keys, tools or any other objects having ferrous metal components. The invention could include a ferrous metal container, or box, to hold ferrous or non-ferrous metal objects, within the container. The container can be sized and shaped for convenience of the use and location, and available space.
Although specific embodiments of the present invention have been described, it will be understood by those of skill in the art that there are other embodiments that are equivalent to the described embodiments. Accordingly, it is to be understood that the invention is not to be limited by the specific illustrated embodiments, but only by the scope of the appended claims.
