The curved plates 10, 20, 30 have a squid shape with an enlarged head end and tail end, and can be another shape having one end that increases in width between one end and an opposite end.

(28) A small disc shaped magnet 40 can be fixed and located in the middle of the disc housing 1.

(29) FIG. 2A is a top view of the base/hub 100 which can be the lower support portion of the novel combination of a cup/compartment 1 with base/hub 100 used for magnetically holding beverage containers thereon. The base/hub 100 can also have a cylindrical disc shaped configuration formed from the same material as the upper cup/compartment 1. FIG. 2B is a side view the base/hub 100 of FIG. 2A along arrow 1B. The base/hub 100 can include a plurality moveable small disc magnets, such as three magnets 110, 120 and 130 that can slide up and down in respective vertical channels 115, 125, 135. Each of the vertical channels 115, 125, 135 can have a diameter slightly larger than the diameter of each of the three perimeter magnets 110, 120, 130, and each of the channels 115, 125, 135 can have a height greater than the width (thickness) of each of the magnets 110, 120, 130. For example, the height of the cavity space in each of the vertical channels, 115, 125, 135 can be approximately twice the width (thickness) of each of the magnets 110, 120, 130.

(30) A small disc shaped central alignment magnet 140 can be fixed and located in the middle of the disc shaped housing 100.

(31) The upper central alignment magnet 40 can have a bottom surface which has an opposite polarity to an upper surface of the lower central alignment magnet 140 so that they attract one another.

(32) The slidable and vertically moveable lower perimeter magnets 110, 120, 130 can be magnetically attracted to the curved plates 10, 20, 30. The upper surface of the lower perimeter magnets 110, 120, 130 can have a polarity that is opposite the polarity of the lower facing surface of the upper central alignment magnet 40. The invention can use magnet designs that function with either polarity of the center magnet. One uses attraction and the other repulsion. The hovering behavior of the outer magnets differ a bit but the attachment and resulting engagement are similar). The enlarged head ends 13, 23, 22 of the curved metal plates 10, 20, 30 can have each have a diameter similar to the diameter of the lower fixed circular disc magnets 110, 120, 130.

(33) FIG. 3A is a top partial ghost view of the cup/compartment 1 of FIGS. 1A-1B placed on top of the base/hub 100 of FIGS. 2A-2B with the perimeter magnets 110, 120, 130 in the base/hub 100 disengaged from the curved metal plates 10, 20, 30 in the upper cup/compartment. FIG. 3B is a side view of FIG. 3A along arrow 1B. FIG. 3C is a cross-sectional view of the cup/compartment 1 on top of the base/hub 100 of FIG. 3A along arrows 3C.

(34) FIG. 4 is a perspective view of the cup/compartment 1 placed on the top of the base/hub 100 of FIGS. 3A-3C in a disengaged position with the cup/compartment 1 about to be rotated in either direction of arrow R.

(35) FIG. 5A is a top partial ghost view of the cup/compartment 1 placed on top of the base/hub 100 of FIGS. 3A-3C, 4 with the cup/compartment 1 rotated to an engaged position. FIG. 5B is a side view of the cup/compartment 100 of FIG. 5A along arrow 5B. FIG. 5C is a cross-sectional view of the cup/compartment 100 of FIG. 5A along arrows 5C.

(36) Referring to FIGS. 1A-5C, the upper compartment/cup 1 can be either initially fixed on the bottom of a beverage container, such as but not limited to insulated double walled stainless steel tumbler, insulated cup, and the like. Additionally, the upper compartment/cup 1 can be separately adhered to the bottom of a beverage container, by various fastening techniques, such as but not limited to peel and stick tape, hook and loop fasteners, mushroom headed interlocking fasteners, and the like.

(37) The lower hub/base 100 can be initially built into a support surface so that the top of the hub/base 100 is flush with the adjacent support surface.

(38) FIG. 6 is a perspective view of the cup/compartment 1 with base/hub 100 in use in a vehicle with the hub/base 100 factory installed into a support surface, such as but not limited to an upper generally horizontal surface 155 of a central console 150. Other surfaces in a vehicle can be used, such as but not limited to armrests, dashboard surfaces, and the like.

(39) Before the invention is used, the upper compartment/cup 1 is physically separated from the base/hub 100 so that there is no magnetic attraction between these parts. At this point, the perimeter disc shaped magnets 110, 120, 130 are physically located at the bottom of the base based on the central magnet in the base that repulses the perimeter magnets and forces them to the bottom of the base/it is a magnetic spring). Depending on orientation and configuration the center magnet can also attract to pick the outer perimeter magnets up in the bottom of each of the vertical channels 115, 125, 135.

(40) Next, the user can move the beverage container with the upper compartment/cup 1 over the hub/base 100, and the upper compartment/cup 1 can initially be oriented so that the upper alignment magnet 40 is attracted to the lower alignment magnet 140, while the narrow ends 11, 21, 31 of the curved metal plates 10, 20, 30 are initially placed over the disc shaped perimeter magnets 110, 120, 130 in the hub/base 100.

(41) Next, the user, can rotate the upper compartment/cup 1 counter-clockwise so that the widening portions 12, 22, 32 of the curved metal plates 10, 20 pass over the lower magnets 10, 20, 30 and are magnetically attracted to the lower perimeter magnets 110, 120, 130 until the lower perimeter magnets 110, 120, 130 overcome the opposing forces with the underside of the upper alignment magnet 40, and snap up in each of the vertical channels 115, 125, 135. The quick upward snapping of the magnets sliding upward in the each of the vertical channels 115, 125, 135 to when they hit the top of each of the closed channels 115, 125, 135 causes a sharp snap sound, which indicates to the user that the upper compartment/cup 1 is now locked to the base/hub 100.

(42) Rotating the upper compartment/cup 1 in a reverse direction, such as clockwise can allow the upper compartment/cup 1 to be physically separated from the base/hub 100.

(43) FIG. 7A is a top view of another embodiment with the novel cup/compartment 200 built into the bottom of a cup in an insulation sleeve for a beverage container. FIG. 7B is a side view cup/compartment of FIG. 7A along arrow 7B. This alternative cup/compartment 200 can also include a plurality of metal curved plates 210, 220, 230 and central alignment magnet 240 that are similar to and function similar to the upper compartment/cup 1 previously described.

(44) The novel base/hub 100, 200 can be generally rigid, and can consist of a flexible material, capable of installation on flat surfaces and/or bent over rounded surfaces.

(45) Although FIG. 6 shows an application to a vehicle, the invention can be used with all types of vehicles, such as but not limited to automobiles, boats, (all-terrain vehicles (ATV's), snowmobiles, recreational vehicles (RV's), personal watercraft, lawn tractors, golf carts, kayaks, appliances, farm equipment, motorcycles. Additionally, the invention ca be used in other applications, such as being built into or retrofitted for use with furniture (such as but limited to tables), coolers, stadium seating, and the like, or surface mounted, retrofit kits.

(46) Although the drawings show the metal plates in the hub, and the moveable magnets in the base, the invention can work with the metal plate in the base and the moveable magnets in the hub.

(47) The invention can work by only using a hub part, without a separate part having a metal plate. The hub can have a moveable magnet where the hub is attached to any surface having metal, such as but not limited to a metal lawnmower frame, metal table, metal chair, and the like. By attaching the hub with moveable magnet to a metal surface, the moveable magnet itself would not be accelerating onto that metal surface. The user can rock the hub to remove it from the metal surface, such as tilting the hub relative to the metal surface.

(48) FIG. 8A is a side cross-sectional view of another embodiment 300 of a hub 310 with a single moveable magnet 330 with the magnet 330 in an up position in a channel 320. FIG. 8B is another view of the embodiment 300 of FIG. 8A with the moveable magnet 330 moved to the bottom 328 of the channel 320 when the hub 310 is placed on a surface 380 having metal.

(49) The moveable magnet 330 can initially be located in the top 322 of the channel 320 by either the moveable magnet 330 being attracted to a fixed metal plate 340 in the top of the channel, or alternatively, by the moveable magnet 330 being repelled by the fixed magnet 350 in the bottom of the hub 310. As such, in this embodiment, either the fixed metal plate 340 or the fixed bottom magnet 350 are separately used.

(50) Referring to FIGS. 8A-8B, hub 310 can be a beverage container such as an insulation sleeve that can fit about bottles or cans, or be part of the bottom of an existing beverage container as previously described. A single channel 320 can be located in the base of the hub 310 having a moveable magnet 330. Initially, the moveable magnet can be attracted to the top 322 of the channel 320 by a metal plate 340 that is fixed to the top 322 of the channel 320.

(51) When the hub 310 is placed on a metal surface 380, the moveable magnet can be attracted to the bottom 328 of the channel 320 by the larger area metal surface 380 underneath the hub 310. Lifting the hub 310 away from the metal surface 380, then causes the smaller metal plate 340 to attract the moveable magnet 330 to move back to the top 322 of the channel by being magnetically attracted to the fixed metal plate 340.

(52) The moveable magnet 330 can also be initially located in the top 322 of the channel 320 by being repelled from a like polarity fixed magnet 350 that is located in the bottom of the hub 310.

(53) When the hub 310 is placed on a metal surface 380, the moveable magnet 330 can be attracted to the bottom 328 of the channel 320 by the larger area metal surface 380 underneath the hub 310 which overcomes the initial repelling action of the small fixed magnet 350. Lifting the hub 310 away from the metal surface 380, then causes the fixed magnet 350 to repel the moveable magnet 330 back to the top 322 of the channel.

(54) FIG. 9A is a side cross-sectional view of still another embodiment 400 of a hub 410 with a plurality of moveable magnets 430, 470 with the magnets 430, 470 in an up position in their respective channels 420, 460. FIG. 9B is another view of the embodiment 400 of FIG. 9A with the moveable magnets 430, 470 moved to the bottom 428, 468 of their channels 420, 460, when the hub 410 is placed on a surface 490 having metal.

(55) The channels 420, 460 can be placed about the perimeter of the base of the hub 410 and spaced apart from one another. While two channels 420, 460 are shown, three or more channels, each with moveable magnets can be used.

(56) Referring to FIGS. 9A-9BB, hub 410 can be a beverage container such as an insulation sleeve that can fit about bottles or cans, or be part of the bottom of an existing beverage container as previously described. A plurality of channels 420, 460 can be located in the base of the hub 410 having respective moveable magnets 430, 470. Initially, the moveable magnets can be attracted to the tops 422, 462 of the channel 420, 460 by metal plates 440, 480 that are fixed to the tops 422, 462 of the channels 420, 460.

(57) When the hub 410 is placed on a metal surface 480, the moveable magnets 430, 470 can be attracted to the bottoms 428, 468 of the respective channels 420, 460 by the larger area metal surface 480 underneath the hub 410. Lifting the hub 410 away from the metal surface 480, then causes the smaller fixed metal plates 440, 480 to attract the moveable magnets 430, 470 to move back to the tops 422, 462 of the respective channels 420, 460 by being magnetically attracted to the fixed metal plates 440, 480.

(58) The moveable magnets 430, 470 can also be initially located in the tops 422, 462 of the respective channels 420, 460 by being repelled from a like polarity fixed magnet 450 located in the bottom of the hub 410.

(59) When the hub 410 is placed on a metal surface 480, the moveable magnets 430, 470 can be attracted to the bottoms 429, 468 of the channels 420, 460 by the larger area metal surface 480 underneath the hub 410 which overcomes the initial repelling action of the small fixed magnet 450. Lifting the hub 410 away from the metal surface 480, then causes the fixed magnet 450 to repel the moveable magnets 430, 470 back to the tops 422, 462 of the respective channels 420, 460.

(60) If the support surface is not metal, a metal plate or metal coaster can be pre-attached to the surface, by any type of fastening system, such as but limited to peel and stick tape, hook and loop fasteners, and the like.

(61) The novel invention automatically engages a proximity change allowing the use of a magnet that would otherwise be far too strong to easily attach and detach an object as needed.

(62) The automatic engagement (movement) of magnets resolves all of the flaws inherent with traditional magnetic attachment: 1) No longer need to compromise between attachment strength and burden of removalyou now have strong AND easy to remove, essentially ON and OFF magnetism. 2) Greatly reduces acceleration/jolt of attachment and detachment 3) Creates audible and tactile click 4) Requires no power source to increase and decrease attachment 5) Requires zero moving parts (aside from magnets) 6) Infinitely variable attachment strengths depending on magnet count, size, composition and configuration.

(63) The invention can work with any ferromagnetic metal in the cup. The prototype you have in your office has steel washers in the cup.

(64) While an embodiment uses squid shaped plates, the plates can have other geometric shapes and any other shape that can provide similar effects that allows for the use of automatically engaging (moving) magnets.

(65) The novel invention can be used with other configurations of magnets move up or down which drastically increases the attachment, creates tactile and audible click, prevents acceleration when setting cup/object down and allows for easy removal.

(66) While the outer shape of the base and compartment in the figures shows circular shapes, the outer shape of the base and the compartment can include any other geometric shape and the like.

(67) Although the figures show the invention using a beverage holder supported on a generally horizontal surface, the invention can be used with a holder that supports objects that are not beverages. For example, the objects associated with the container can include but are not limited to portable handheld phones, GPS (global positioning) devices, light sources, such as but not limited to light bulbs, and the like.

(68) Additionally, the invention is not restricted to the horizontal support surfaces, and can be used on slanted or angled support surfaces as well as against a vertical support surface, and the like.

(69) While the invention has been described, disclosed, illustrated and shown in various terms of certain embodiments or modifications which it has presumed in practice, the scope of the invention is not intended to be, nor should it be deemed to be, limited thereby and such other modifications or embodiments as may be suggested by the teachings herein are particularly reserved especially as they fall within the breadth and scope of the claims here appended.
