BACKGROUND OF THE INVENTION
Field of the Invention
[0001] This description generally relates to the field of table gaming, and more particularly
to card holding devices, for example card shoes that hold a number of cards during
a playing card game and allow cards to be extracted from the card shoe one at a time,
more specifically the invention relates to a wedge assembly for a card shoe.
Description of the Related Art
[0002] Conventional card shoes 10 are typically sized to receive two to eight standard decks
of playing cards, with fifty-two (52) playing cards per standard playing card deck.
[0003] Figure 1 shows a conventional, non-automated card shoe 10 that includes a housing
12, a playing card support surface 14, and a playing card wedge 16. The housing includes
an opening 18 where playing cards are extracted one at a time during a playing card
game. The housing 12 includes a playing card support surface 14 sloping at a downward
angle 20 going from the rear of the housing 12 to the front. The playing card support
surface 14 supports the playing cards and the playing card wedge 16. The playing card
wedge 16 includes a slanted surface 22 that skews or offsets the playing cards in
the housing 12 relative to one another. An optional roller 24 may be rotationally
coupled to the playing card wedge 16 to allow the playing card wedge 16 to easily
move down the playing card support surface 14. The playing cards are compressed between
the slanted surface 22 of the playing card wedge 16 and a complementary, slanted front
cover 26 of the housing 12. The downward angle 20 of the playing card support surface
14 takes advantage of gravity to bias the playing cards toward the front of the housing
12 under their own weight as well as under the weight of the playing card wedge 16.
[0004] Another type of card shoe, which is not illustrated, is similar to the above-described
card shoe except that a spring couples the playing card wedge to the housing. The
spring operates alone or to augment the force of gravity by applying a force to bias
the playing card wedge toward the opening in the housing. As the playing card wedge
moves closer to the opening, the spring contributes less and less to the overall force
biasing the playing card wedge toward the opening. At some point, before all the playing
cards are removed from the card shoe, the force of the spring biasing the playing
card wedge toward the opening becomes nearly negligible. This situation typically
occurs when there are less than two decks (
i.e., 104 playing cards) remaining in the card shoe.
[0005] US-A-640214 discloses another example of a card shoe.
[0006] For either of the above-described conventional card shoes, the amount of force biasing
the playing cards toward the opening in the card shoe decreases as fewer cards remain
in the card shoe. In the first described card shoe, the weight of the playing cards
contributes significantly to the force biasing the playing cards toward the front
of the card shoe. Consequently, removing the playing cards from the card shoe results
in less resistance as the dealer applies finger pressure to remove a playing card
from the card shoe. Likewise, the reduction in the biasing force applied by the spring
in the second type of card shoe, also results in less resistance as the dealer applies
finger pressure to remove a playing card from the card shoe.
[0007] The practical consequence of these conventional card shoes is that it becomes more
difficult for the dealer to extract the remaining playing cards from the card shoe
when there is little to no resistance or biasing force (
e.g., (wedge mass + card mass) or (wedge mass + spring force + card mass)) against the
finger pressure applied on the playing card by the dealer. Thus, the dealer is often
unable to firmly contact the playing card present in the opening of the housing, thus
making it difficult for the dealer's finger to frictionally grip and withdraw the
next playing card to be dealt. As the dealer pushes harder against the playing card,
the wedge reacts by moving rearward in the housing, further exacerbating the situation
and causing the dealer to fish for the playing card in the card shoe. Accordingly,
it would be desirable to have a card shoe that addresses the aforementioned problems
and permits easier and smoother removal of the playing cards from the card shoe, without
regard to the number of playing cards remaining in the card shoe.
SUMMARY OF THE INVENTION
[0008] This description generally relates to a card shoes for holding and distributing playing
cards during a playing card game. The card shoe typically holds between two (2) to
eight (8) decks of playing cards. The card shoe includes a wedge that biases the playing
cards toward a playing card extraction opening in the card shoe. The wedge can be
acted on by gravity, another mechanical mechanism, for example a spring, and/or both.
The wedge may include a shaft, a clutch assembly, and a roller, where the clutch assembly
permits the roller to rotate in only one direction. When the clutch assembly locks
onto the shaft, the wedge resists backward movement within the card shoe, which in
turn allows a dealer to put pressure on the playing cards being extracted without
pushing the wedge away from the playing card extraction opening.
[0009] In one aspect, a wedge assembly to bias playing cards toward a playing card extraction
opening of a card shoe includes a wedge block having a bottom surface and a card engagement
surface positioned at an angle relative to the bottom surface, the wedge block receivable
in the card shoe; and a roller subassembly having a roller rotationally coupled to
the wedge block to be rotatable in a first rotational direction and lockable to substantially
resist rotation in a direction opposite the first rotational direction.
[0010] In another aspect, a wedge assembly to bias playing cards toward a playing card extraction
opening of a card shoe includes a wedge block having a bottom surface and a card engagement
surface positioned at an angle relative to the bottom surface, the wedge block receivable
in the card shoe; and a roller subassembly having a shaft and a roller, the shaft
coupled to the wedge block and having a first portion concentrically disposed about
a first shaft axis and a second portion eccentrically disposed about a second shaft
axis, the roller coupled to the second portion of the shaft and rotatable about the
second shaft axis.
[0011] In yet another aspect, a card shoe includes a housing having a playing card support
surface and an opening, the playing card support surface arranged to receive and support
a plurality of playing cards, the opening sized to permit extraction of at least some
of the plurality of playing cards from the housing; and a wedge assembly having a
wedge block and a roller subassembly, the wedge block includes a bottom surface and
a card engagement surface positioned at an angle relative to the bottom surface, the
wedge block is receivable in the housing of card shoe, the roller subassembly includes
a roller rotationally coupled to the wedge block and rotatable in a first rotational
direction and lockable to substantially resist rotation in a direction opposite the
first rotational direction.

DETAILED DESCRIPTION OF THE INVENTION
[0013] In the following description, certain specific details are set forth in order to
provide a thorough understanding of various embodiments of the invention. However,
one skilled in the art will understand that the invention may be practiced without
these details. In other instances, well-known structures associated with card shoes
have not been shown or described in detail to avoid unnecessarily obscuring the description.
[0014] Unless the context requires otherwise, throughout the specification and claims which
follow, the word "comprise" and variations thereof, such as, "comprises" and "comprising"
are to be construed in an open, inclusive sense, that is as "including, but not limited
to."
[0015] Reference throughout this specification to "one embodiment" or "an embodiment" means
that a particular feature, structure or characteristic described in connection with
the embodiment is included in at least one embodiment. Thus, the appearances of the
phrases "in one embodiment" or "in an embodiment" in various places throughout this
specification are not necessarily all referring to the same embodiment. Furthermore,
the particular features, structures, or characteristics may be combinable in any suitable
manner in one or more embodiments.
[0016] The headings provided herein are for convenience only and do not interpret the scope
or meaning of the claimed invention.
[0017] This description generally relates to card shoes for holding and distributing playing
cards during a playing card game. Card shoes are generally used in casinos and often
hold between two (2) to eight (8) decks of playing cards. However, it is understood
that some card shoes may hold a fewer or a greater number of playing cards. Further,
some card shoes may be automated, employing electro-mechanical and/or electro-optical
components to read machine-readable and/or human readable indicia carried by the playing
cards.
[0018] Figure 2 shows a card shoe 100 having a housing 102 and a wedge assembly 104, according
to the illustrated embodiment. The housing 102 includes a playing card support surface
106, sidewalls 108, and a front cover 110. The playing card support surface 106, the
sidewalls 108, and the front cover 110 form a receptacle 111 configured to receive
and support a number of playing cards (not shown). The playing card support surface
106 may or may not slope downward from the rear of the housing 102. As noted above,
a sloped surface may take advantage of gravity as the sole or partial biasing force
that urges the playing cards toward the opening 112 of the housing 102.
[0019] The front cover 110 includes an opening 112 from which a dealer can extract the playing
cards from the card shoe 100. The opening 112 is sized to allow the dealer to place
a finger or two onto the next playing card that is to be removed from the card shoe
100. The playing card support surface 106 can cooperate with the front cover 110 to
skew or otherwise offset the playing cards relative to one another, which tends to
increase the likelihood that playing cards are extracted one at a time from the card
shoe 100. It is understood that sometimes, however, more than one playing card is
extracted from the card shoe 100, whether done intentionally or because two playing
cards become stuck together.
[0020] The housing 102 further includes a slot or track 114. The track 114 can be sloped
or otherwise configured to cause the wedge assembly 104 to move forward, toward the
opening 112. One embodiment of the sloped track 114 is best illustrated in Figure
7. A spring 116 may be coupled to guides 117, 119 received in the track 114. The guides
117 may be fixed to the housing, whereas the guides 119 couple the wedge assembly
104 to the spring 116 and are operable to move along the track 114. In one embodiment,
the spring 116 is an extension spring anchored proximate the front of the housing
102 that biases or urges the wedge assembly 104 toward the opening 112. In another
embodiment, the spring is a compression spring anchored proximate the rear of the
housing 102 that biases or urges the wedge assembly 104 toward the opening 112.
[0021] Figures 3 and 4 show the wedge assembly 104 having a wedge block 105 configured with
a sloped engagement surface 118 disposed between first and second side surfaces 120.
The wedge assembly 104 further includes guides 119, 122 extending from each of the
first and second surfaces 120. The guides 119 are coupled to the spring 116 (Figure
2) and may also be supported in the track 114 of the housing 102 as mentioned above.
The guides 122 may also be supported in the track 114 of the housing 102 counteracting
any overturning moment that may cause the wedge assembly 104 to rotate about the guides
119. Figure 4 shows a roller 124 of a roller subassembly 125, which is part of the
wedge assembly 104, extending at least slightly below a bottom surface 126 of the
wedge block 105.
[0022] Figure 5 shows the roller subassembly 125 in detail. The roller subassembly 125 includes
the roller 124, which is rotatably fixed to an anti-reversing clutch assembly 126A,
which in turn is rotatably coupled to a shaft 128. In one embodiment, the roller 124
is made from a urethane material and press fit onto the clutch assembly 126A. The
clutch assembly 126 may be an overrunning clutch or drawn cup roller clutch. This
type of clutch assembly 126 permits the roller 124 to freely rotate in a first direction,
yet positively locks onto the shaft 128 to substantially prevent reverse rotation
(
i.e., rotation that is counter or opposite to the first rotational direction) of the roller
124.
[0023] The shaft 128 includes a tool engagement portion 130 and a shaft centerline or axis
132. It is understood and appreciated that the shaft centerline 132 is to be distinguished
from a roller rotational centerline or axis 133, as illustrated and described in more
detail below. During operation, the roller 124 and portions of the clutch assembly
126A rotate in unison on the shaft 128 and about the roller rotational axis 133. In
the illustrated embodiment, the shaft 128 does not rotate relative to the wedge assembly104.
[0024] Figures 6 and 7 show the shaft 128 having a first section 134, a second section 136,
and a third section 138, where the second section 136 is disposed between the first
and third sections 134, 138. In the illustrated embodiment, the second section 136
is offset relative to the shaft axis 132 and concentrically formed about the roller
rotational axis 133. The first and third sections 134, 138 are not offset, which means
these sections are concentrically formed about the shaft axis 132. The eccentricity
of the second section 136 is indicated by identifying that a first radial depth 140
of the second section 136 extends less than a second radial depth 142 on an opposite
side (
i.e., 180 degrees) of the second section 136. Since both radial depths 140, 142 are measured
from the shaft axis 132, it is understood that the second section 136 must be eccentrically
formed about and/or offset relative to the shaft axis 132. The radial depths 140,
142 vary in height about the circumference of the second section 136 of the shaft
128.
[0025] The first section 134 and the third section 138, on the other hand, are concentrically
formed about and/or not offset relative to the shaft axis 132. The radial depths 144,
146, which are measured from the shaft axis 132 are equivalent, thus it is understood
that the first section 134 and the third section 138 are concentric with respect to
the shaft axis 132 and with respect to one another.
[0026] One purpose for eccentrically offsetting the second section 136 is to allow for the
adjustment of the roller 124 beyond the bottom surface 126 of the wedge block 105
(Figure 4). Adjusting the roller 124 to protrude by a lesser or greater amount beyond
the bottom surface 126 is accomplished by engaging the tool engagement portion 130
of the shaft 128 with an appropriate tool, for example a screwdriver. Because the
shaft 128 is fixed to the wedge assembly 104, the roller 124 and portions of the clutch
assembly 126A rotate about the second section 136 of the shaft 128.
[0027] Figure 8 shows the card shoe 100 as the wedge assembly 104 is moved along the track
114. As the dealer removes each playing card, the biasing force of the spring 116,
the weight of the wedge assembly 104, and/or the weight of the playing cards urges
the wedge assembly 104 toward the front cover 110. The roller 124 is free to rotate
in a direction indicated by the arrow 148. As the dealer applies pressure to the next
card to be removed, the anti-reversing clutch assembly 126A positively locks onto
the shaft 128 to substantially prevent reverse rotation of the roller 124 and thus
prevents the wedge assembly 104 from moving away from the front cover 110 and the
opening 112 of the housing 102. The second section 136 of the shaft 128 and the frictional
engaging portion of the clutch assembly 126 may be relatively dimensioned to achieve
a desired amount of frictional locking of the clutch assembly 126 onto the second
section 136 of the shaft 128.
[0028] Once all or a desired number of cards are removed from the card shoe 100, the wedge
assembly 104 can be reset in the card shoe 100. In one embodiment, the wedge assembly
104 includes a handle 150 that can be used to separate the roller 124 from the playing
card support surface 106 of the card shoe 100. By lifting up on the handle 150, the
roller 124 will no longer be in contact with the playing card support surface 106
and the wedge assembly 104 can be easily moved away from the front cover 110 and the
opening 112 to allow more playing cards to be loaded in the receptacle 111 of the
card shoe 100.
[0029] The various embodiments described above can be combined to provide further embodiments.
[0030] These and other changes can be made to the invention in light of the above-detailed
description. In general, in the following claims, the terms used should not be construed
to limit the invention to the specific embodiments disclosed in the specification
