Description

FIELD OF THE INVENTION

This invention relates to card games where cards are upturned.

BACKGROUND OF THE INVENTION

A popular game particularly among children involves using cupped hands to direct a blast of air to the base of a pack of cards placed face down on a table or other flat surface, so as to upturn as many of the cards as possible. The player who exposes the most cards from the pack is the winner.
It can be challenging to produce an air blast of sufficient strength using cupped hands.
Document US-B1-7927177 discloses a device comprising all the technical features set out in the preamble of claim 1.
US Patent No. 5,624,121 discloses a game comprising a plurality of rigid playing discs stacked one on top of another, each player being provided with a turn for striking a topmost one of the playing discs towards a periphery thereof so as thereby to upturn a number of the playing discs in the stack, the player claiming for himself those discs whose upper surface is downmost. An object of the game is to maximize the number of upturned playing discs.
US2014287392 discloses a board game instrument including at least two projectiles, a launch pad, at least two baskets, a game board, and at least two magic cards. The projectiles are thrown in a basket using a launch pad, which launches the projectile using an elastic force.
US Patent No. 2,187,524 discloses game which utilizes a projector device, projectiles and a variably configured target area containing a plurality of individual targets.
None of these prior art games discloses a device that causes a blast of air to upturn cards from a stack.

SUMMARY OF THE INVENTION

An object of the invention is to provide a device or accessory that may be used instead of cupping one's hands to a similar effect.
This object is achieved by a device for flipping stacked cards from a first position to an opposite second position according to claim 1.

DETAILED DESCRIPTION OF EMBODIMENTS

In the following description of some embodiments, identical components that appear in more than one figure or that share similar functionality will be referenced by identical reference symbols.
With reference to the figures, there is shown a device 10 for flipping stacked cards 11 from a first position shown in Fig. 2 to an opposite second position shown in Fig. 3. Typically, in the first position the cards are face down and in the second position they are exposed, but the game according to the invention may be played with the cards initially exposed since the game's skill resides in the player's ability to flip as many cards from the stack as possible.
In a first embodiment shown in Figs. 1a and 1b, the device 10 comprises a flexible hollow cup-shaped member 12, typically formed of rubber or plastic having a base portion 13 defining a rim 14, and a recess 15 formed in a portion of the rim so that when the base portion is placed on a generally flat surface 16, a single elongated recess 15 forms an opening 17 that allows air to pass through when pressure is applied to an outer surface of the cup-shaped member.
The device 10 may be used to play a game for flipping cards, whose rules comprise:

(a) placing a stack of cards on a generally flat surface 16;
(b) disposing the device in close proximity to the stack of cards with the recess facing the cards; and
(c) exerting pressure on an outer surface of the device so as to direct a blast of air toward a base of the stack of cards and thereby flip cards from a first position to an opposite second position.

The player who flips the most cards is the winner.
Typically, a player exerts pressure by pushing on the outer surface of the device with his or her hands 18.
Figs. 4a and 4b depict a second embodiment where instead of only a single recess, multiple recesses 15 are formed in the rim of the cup-shaped member 12 thus forming multiple openings 17 when the device is placed on the surface 16.
Fig. 5 depicts a third embodiment wherein small apertures 19 are formed around a periphery of the cup-shaped member 12 toward the rim 14. The apertures 19 form openings through air passes when pressure is applied to the outer surface of the cup-shaped member 12. A single elongated aperture or slot as shown in Fig. 8a may also be used either on its own or in conjunction with a recess 15.
Figs. 6a and 7a show pictorially a two-part assembly 20 according to variations of a fourth embodiment prior to assembly and Figs. 6b and 7b show the respective assemblies during use. In effect, the fourth embodiment uses the same device 10 as described above with reference to Figs. 1 and 5 but instead of placing the device 10 on a flat surface, such as a table, with the apertures 19 or recesses 15 proximate the table, the device 10 is disposed with the apertures 19 or recesses 15 uppermost thus forming a compressible hollow cup with the apertures 19 or recesses 15 close to its rim 14. A second compressible cup-shaped plunger element 21 of diameter slightly larger than that of the device 10 is now assembled on top of the device 10 and may optionally be sealed or otherwise joined thereto. When pressure is brought to bear on the plunger element 21, air is pushed out of the apertures 19 or recesses 15 with sufficient pressure to upturn a pack of cards in its vicinity.
Figs. 8a and 8a show pictorially a two-part assembly 20 according to another variation of the fourth embodiment prior to and during assembly, respectively. This variation is similar to that shown in Figs. 6a and 6b except that instead of forming a plurality of apertures there is formed a single elongated slot 22. The different variations may be combined so that, for example, the lower device 10 may have both apertures and a recess or an elongated slot and a recess.
It has been found experimentally that the first embodiment works particularly effectively and allows a skilled player to upturn all the cards in an average stack. The second and third embodiments were less effective although they did succeed in upturning many if not most of the cards in the stack. The fourth embodiment was also found to be extremely effective. The effectiveness of the apertures in Fig. 5 depends on how close they are located to the rim since this determines to what extent air reaches the lower surface of the card stack. If air does not succeed in forcing its way underneath the bottom of the stack, then the bottom cards in the stack will not be flipped.
It should be noted that while the invention has been described with particular reference to regular playing cards as shown pictorially in Figs. 2 and 3, no such limitation is implied. Thus, the device according to the embodiment may be used in conjunction with other types of cards, such as those collected by children as well as a labels, sticky labels having a removable backing and used prior to removal thereof, and any other card having visually distinguished upper and lower surfaces. Likewise, while the recesses are shown as having arcuate contours, again no limitation is implied and good results have been achieved in practice using rectangular-shaped recesses.
