AT512166B1 - Playing card shuffler - Google Patents

Abstract

The Spielkartenmischgerät of wood, metal, plastic or similar material, consists of two shells (1), (2) which are connected to a hinge (3). It is only slightly larger than the playing card deck (10) itself and performs professional card blending operations such as bow blending (riffle shuffle), intertwining (weave shuffle) and lifting (cutting) with the simplest of hands. The Spielkartendeck (10) must be removed from the device at any time. The game card shuffling device does not require motors, gears, batteries or noise. The Spielkartenendeck (10) is directed at all times with the image sides down and is moved ten millimeters above the table surface. Due to the extremely short time required and the ease of use for a mixing process, the requirement for at least four to seven mixing processes, for a sufficiently mixed Spielkartenendeck, even by laymen and fine motor skills inexperienced players can be easily met.

Description: The invention relates to a playing-card mixing device that enables all players, including lay people and people who are unfamiliar with fine motor skills, to carry out professional playing-card mixing operations quickly, without errors, several times in succession and for all to see. The game card shuffler does not require any motors, gearboxes or batteries, it does not generate any noise and it casinogically hides the playing card image pages at any time during the mixing process.

In card game types that sort by their rule-compliant game play the playing cards by color, or generate ascending and descending episodes of card values, or card games where is mixed in very short time intervals, it is necessary to short, effective and mixing quickly repeatable. The lowest number of mixing cycles of a 52-sheet card deck is four, but mathematically seven, to guarantee a good mixing result. Where the blending (riffle shuffle) or intertwining (weave shuffle) is a prerequisite for a good mixing result. For both types of blending, an exactly aligned playing card deck is required.

Prominent playing cards from the playing card deck hinder the random mixing.

Previously shown and described handheld Spielkartenmischgeräte for the private sector require prior to the mixing process preparatory handles, outside the device, and close the mixing process only with additional handles, outside of the device from. These hand grips and the positioning of the playing cards in hand-operated playing-card blenders are not casino-appropriate, disclose the playing-card image pages to the players and significantly increase the duration of a blending cycle. Therefore, especially in private player rounds, mixing is done insufficiently and the realization that a 52-sheet playing card deck is mixed well enough from four or seven mixing cycles is disregarded. Furthermore, only either riffle shuffle or weave shuffle can be performed. This can be seen in the following patents.

GB 379,483 A, US 2,583,871 A: These devices can perform the blending (riffle shuffle), in fixed or movable shells, which position the Spielkartendeckhälften at a fixed predetermined angle to each other. The playing card deck must be divided manually before each mixing process and inserted into the bowls. After the mixing process, it must be taken out of the bowls and again pushed together by hand to a new playing card deck. Only then can a new mixing cycle begin. Other types of card mixing can not be performed.

US 2,705,638 A: The device can perform the intertwining (weave shuffle) in movable shells, which position the Spielkartendeckhälften at a fixed predetermined angle to each other. After the mixing process, it is taken out of the bowls and again pushed together by hand to a new playing card deck. Only then can a new mixing cycle begin. The playing cards are perpendicular to the table level and the sides are visible to all players. Other types of card mixing can not be performed.

The invention described below thus shows the solution to simplify the mixing process of a playing card deck so that the game cards remain in the game card mixing device at any time and the mixing process is complete and accurate and extremely shortened and that several types of card mixing, in one and the same device immediately after one another. The image pages of the playing cards always remain parallel to the table surface and hidden. This is inventively achieved by the characterizing features of claim 1 and all other dependent claims and the invention will now be explained with reference to an embodiment which is shown schematically in the drawings. 1/8 Austrian Patent Office AT512166B1 2013-06-15

The Spielkartenmischgerät (Fig.1), consists of two symmetrical, shell-shaped parts 1,2, which are connected by a hinge 3. The distance E from the hinge to the rear walls 9 is 25 millimeters. The playing card deck 10 is enclosed by the rear walls 9 and the side walls 8 and the bearing surfaces 4 and lies parallel to the table surface 13. The image pages of the playing cards are always hidden during all mixing operations.

The base surfaces 6 of the two shells 1.2 are located and slide during all operations described below on the table surface 13 and the side edges 7 of the base surfaces 6 are rounded to guarantee easy sliding.

Adjacent to the support surfaces 4 (Fig.2) are the wedge surfaces 5, which are chamfered to the table surface 13 out to always raise the bottom card when closing the Spielkartenmischgerätes and again lead to the support surfaces 4.

The side walls 8 (Figure 4) and rear walls 9 are higher B than the Spielkartendeck, the distance A of the support surfaces 4 of the table surface 13 is at least ten millimeters.

The (shown in Figure 1 to Figure 4) shown wedge gap 17, as shown (in Figure 5), closed by pressure on the outer walls 12, so that the length of the opening C is smaller than the Spielkartendecklänge D. Only by inserting the Spielkartendecks the wedge gap 17 is opened again (Figure 6).

[0022] Blending (riffle shuffle): (Figure 7) This blending style is suitable for older, slightly thicker, roughened cards at the corners and edges. By opening the Spielkartenmischgerätes to 90 to 105 degrees, the Spielkartendeck 10 with the thumb in two Spielkartendecks 10 is approximately halved and placed in a partially overlapping position and allows a bow mixing (riffle shuffle). The index fingers push the card deck corners 16 perpendicular to the support surfaces 4 during all movements. The back walls 9 and the side walls 8 prevent the playing cards from slipping therefrom.

Close: (Figure 9) The closing of the playing card mixing device after the mixing process is achieved by pushing together the outer walls 12 and supported from an opening angle of 45 degrees by horizontally pressing the thumb on the card deck corners 15 against the rear walls 9, wherein the wedge surface 5 lifts the bottom card and slides on the support surface 4 2/8 Austrian Patent Office AT512166B1 2013-06-15 leaves. The wedge-shaped gap 17 makes it possible, via the side surfaces 12 and side walls 8, to exert the necessary pressure on the playing card deck 10 in order to align the playing cards in the playing card deck 10 exactly. Thus, the cycle is completed and at the same time the next mixing process prepared without removing the playing card deck 10 from the playing card mixing device.

Weave shuffle: (FIG. 8) As a variant, intertwining (weave shuffle) is carried out with suitable thin plastic playing cards. By opening the Spielkartenmischgerätes to 120 degrees, sliding on the table surface 13, the map deck 10 with the help of the thumb in two, lying at the same height, Spielkartendecks 10 is approximately halved and by the floating position, ten millimeters above the table surface 13, a mixing by pushing the card deck corners 14 into one another (weave shuffle). The back walls 9 and side walls 8 prevent the playing cards from slipping off. The index fingers press during all movements the card cover corners 16 perpendicular to the support surfaces 4. The closing is exactly the same as previously described.

By opening the Spielkartenmischgerätes greater than 120 degrees, the map deck 10 with the help of the thumb in two, lying at the same height, Spielkartendecks 10 is approximately halved and by lifting the former lower half card deck 10 on the other and subsequent closing, lifting allows (cutting). The back walls 9 and side walls 8 prevent the playing cards from slipping off. Closing is exactly the same as previously described.

Carriage: (Figure 1) The playing card blender with the inserted and ready mixed playing card deck 10 can be used as a card slide during the game and also serves as a marker for the current position of the dealer (Dealer). Any built-in components such as clocks or other counter displays are possible.

Material: The extremely simple form of the playing card mixing device is suitable for cost-effective production of plastic, but also for solid materials. The small size and low weight of the Spielkartenmischgerätes suggests sales together with a Spielkartenendeck. 3.8
