Description




FIELD OF THE INVENTION




The present invention relates generally to sports balls or game balls. In particular, the present invention relates to a sports ball having a cover which is movable with respect to an interior bladder, and a game ball having at least two linings, which are orientated to minimize overlapping of lining material.




BACKGROUND OF THE INVENTION




Many sports balls and game balls include an inflatable bladder and a cover that surrounds the bladder. Such sports balls include, for example, volleyballs, basketballs, footballs, and soccer balls. Sports balls with inflatable bladders conventionally include a first lining over the bladder for reinforcing the bladder and for maintaining the shape of the bladder. For example, volleyballs have included a cloth lining, which surrounds the bladder. The cloth lining may be formed from a plurality of cloth sheets or panels, which are dipped in a latex adhesive or other adhesive and then applied to the outer surfaces of the inflated bladder. When the adhesive dries, the cloth panels are adhesively secured together and perhaps also adhesively secured to the bladder. The bladder and the lining form the carcass of the volleyball. The cover of the ball is formed from a plurality of panels of leather, synthetic leather, or other cover material which are adhesively secured to the lining. Volleyballs are described, for example, in U.S. Pat. Nos. 4,239,568 and 5,542,662.




Basketballs have included a wound liner layer, which is formed by winding thread or filament around the inflated bladder. The thread is conventionally nylon or similar material and may be dipped in latex glue or polyurethane adhesive before being wound over the bladder. Applying a layer of rubber over the wound bladder and molding the resulting structure under heat and pressure conventionally forms the carcass of a basketball. The cover is thereafter applied to the carcass. Basketballs are described, for example, in U.S. Pat. Nos. 5,310,178, 5,681,233, 5,931,752 and 6,024,661.




U.S. Pat. No. 4,239,568 describes a volleyball in which a layer of lubricant such as talc is interposed between the bladder and a first cloth layer. The lubricant prevents the cloth layer from sticking to the bladder. However, the manufacturing process requires applying the cloth layer to a hollow sphere, which is made from brittle material such as paraffin. The sphere is broken into pieces after the cloth layer is applied. The pieces of paraffin are removed through a slit in the cloth layer, and the bladder is inserted through the slit.




U.S. Pat. No. 5,542,662 describes a modified volleyball, which includes a bladder, and a thin rubber pouch which forms a covering layer over the bladder. The bladder is coated with an inorganic lubricant. The pouch is covered with latex-impregnated cloth and a cover layer.




The prior art volleyballs in which a layer of lubricant covers the bladder can be referred to as floating bladder volleyballs. The floating bladder is not adhered to the cloth layer, and the volleyball has a softer feel than other prior art balls in which both the bladder and the cover were adhesively secured to the cloth layer.




Existing game balls having a lining comprised of a number of sheets adhesively secured to each other are well known, and can include two or more linings wherein each lining is formed from a number of sheets. Such game balls with two or more linings, wherein each lining is formed from a number of overlapping sheets, have drawbacks. Each lining of this type includes a number of overlapped regions wherein portions of two or three separate sheets overlapping each other. Typically, the sheets are applied to the lined surface of the game ball in a manner that is consistent with the arrangement of outer cover panels of the game ball. For example, a conventional volleyball includes eighteen separate cover panels covering the ball. Typically, each lining would also be formed from twelve or eighteen sheets orientated in the approximate position of the cover panels. When two or more such linings are employed in the construction of a game ball, the double and triple overlapped portions of one lining often can be aligned or overlapped with the double and triple overlapped portions of a second lining. These regions of the game ball can response differently than other regions of the ball during manufacturing, particularly during curing, and often can lead to an out of round, misshapened, or otherwise defective appearance, when pressurized. These regions can also create hard spots or dead spots in the ball, which can react differently in use than other regions of the game ball and can result in a ball with an inconsistent and hard feel. These regions can also affect the rotation or the travel of the ball during use.




Thus, there is a need to develop a game ball having two or more linings that does not include regions of overlapped sections of one lining aligned with overlapped sections of a second lining. There is a need for a game ball including two or more linings that has a consistent softer feel. What is needed is a multi-lined game ball that consistently takes a desired shape and performs in a consistent manner during use. It would be advantageous to produce a multi-lined game ball without regions of aligned overlapped lining sections without requiring the implementation of costly and complex manufacturing steps.




SUMMARY OF THE INVENTION




The invention provides a volleyball or other sports ball with a floating cover rather than a floating bladder. Since the player feels the cover and not the bladder, better feel and performance is obtained if the cover can float relative to the carcass of the ball. The floating cover improves the dynamics of the ball and produces an even softer feel than a floating bladder.




The bladder is covered with an adhesive-impregnated lining that provides a load-carrying layer for retaining the shape of the bladder. The bladder and the attached cloth layer form the carcass of the ball. A layer of elastomeric material, which is not attached to the carcass, surrounds the carcass. The elastomeric layer and is movable relative to the carcass. A second lining is applied over the layer of elastomeric material. In a particularly preferred embodiment, the second lining is a layer of adhesive-impregnated cloth that facilitates adhesion of the cover to the elastomeric layer.




According to a principal aspect of the invention, a game ball includes an inflatable bladder, a plurality of first and second lining sheets, and a cover. The first lining sheets substantially cover the bladder to form a first lining. At least a portion of one first lining sheet overlaps at least a portion of another first lining sheet to define a first overlapped region. The first lining includes at least one first overlapped region. The second lining sheets substantially surround the first lining to form a second lining. At least a portion of one second lining sheet overlaps at least a portion of another sheet lining sheet to define a second overlapped region. The second lining includes at least one second overlapped region. The second lining is shifted with respect to the first lining to minimize overlapping of the first and second overlapped regions. The cover is coupled to and substantially surrounding the second lining.




According to another preferred aspect of the invention, a volleyball includes an inflatable bladder, a plurality of first and second lining sheets and a cover. The first lining sheets are arranged in a pattern generally resembling a conventional multi-panel volleyball cover and substantially cover the bladder to form a first lining. At least a portion of three first lining sheets overlap each other to form a first triple-layered region. The first lining includes at least one first triple-layered region. The second lining sheets are arranged in a pattern generally resembling the conventional volleyball cover pattern and substantially surround the first lining to form a second lining. At least a portion of three second lining sheets overlap each other to form a second triple-layered region. The second lining includes at least one second triple-layered region. The second lining is shifted with respect to the first lining such that the second triple-layered regions are generally not disposed over the first triple-layered regions. The cover is coupled to and substantially surrounds the second lining.




This invention will become more fully understood from the following detailed description, taken in conjunction with the accompanying drawings described herein below, and wherein like reference numerals refer to like parts.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




Referring to

FIG. 1

, a volleyball is indicated generally at


10


. The volleyball


10


is one example of a sports ball or a game ball. The present application is directly applicable to other game balls, including, for example, basketballs, soccer balls, footballs, and rugby balls.




The volleyball


10


is a spherical inflatable object. The volleyball


10


preferably includes a bladder


12


, a first lining


14


, an elastomeric layer


16


, a second lining


18


and a cover assembly


20


. Referring to

FIGS. 1 and 2

, the bladder


12


is an inflatable air tube preferably having a spherical shape. The bladder


12


is disposed within the first lining


14


, the elastomeric layer


16


, the second lining


18


and the cover


20


. The bladder


12


enables the volleyball


10


to retain a predetermined amount of air thereby achieving the desired air pressure within the ball


10


. The bladder


12


also contributes to the firmness of the volleyball


10


. The bladder


12


is made of an elastomeric material, preferably 100% butyl rubber. Alternatively, other materials can be used such as, for example, synthetic rubber, natural rubber or any other conventional bladder material. The bladder


12


includes a valve


22


that extends through the first lining


14


, the elastomeric layer


16


, the second lining


18


and the cover


20


.




Referring to

FIG. 3

, the bladder


12


is substantially covered with a first lining


14


to form a carcass


24


. The first lining


14


is a thin layer of material comprised of a plurality of first sheets


26


. Each first sheet


26


is a flexible thin member, preferably made of a cloth. Alternatively, the first sheet


26


can be made of other materials, such as, for example, woven fabrics, unwoven fabrics or other conventional flexible sheet material. The first sheet


26


typically includes an adhesive for attaching the first sheet


26


to adjacent sheets or to the underlying material (such as the bladder


12


). In a preferred embodiment, each first sheet


26


is a layer of adhesive-impregnated cloth. In a particularly preferred embodiment, each first sheet


26


is a 60% polyester and 40% cotton cloth, which was immersed, in latex adhesive. The first lining


14


is applied to the bladder


12


while the bladder


12


is inflated so that the first lining


14


assumes a spherical shape.




The first lining


14


strengthens the bladder


12


and provides a load-carrying layer for retaining the shape of the bladder


12


. The outer surface of the first lining


14


, having a relatively low coefficient of friction, is conducive for enabling relative movement between the first lining


14


and the material surrounding the first lining


14


.




In an alternative preferred embodiment, the first lining


14


can be arranged into six separate sections wherein each section includes one, two or three sheets


26


, and wherein the sheets


26


collectively generally corresponds to the cover panel pattern of a conventional volleyball. In a preferred embodiment, the first lining


14


is comprised of twelve first sheets


26


. The first sheets


26


are arranged in a pattern resembling the pattern of the outer cover panels of a conventional volleyball.




A portion of each first sheet


26


preferably overlaps, or is overlapped by at least one other first sheet


26


. When fully applied to the bladder


12


, the first lining


14


includes a plurality of double and triple overlapped (or layered) regions


28


and


30


. The double overlapped regions


28


occur where a portion of one first sheet


26


overlaps a portion of one other first sheet


26


. The triple overlapped regions


30


occur where a portion of three separate first sheets


26


overlap each other.




The first sheets


26


preferably overlap one or more other first sheets


26


by approximately 10 to 30 mm. In a particularly preferred embodiment, the first sheets


26


overlap each other by approximately 20 mm. Generally, if the sheets


26


are overlapped by less than 10 mm, the sheets


26


may be susceptible to becoming spaced apart or separating during manufacturing or pressurization of the game ball


10


. Separation of the sheets


26


is undesirable because it can lead to the uncovered portion of the bladder


12


outwardly extending when pressurized through the separation in the first lining


14


. Separation of the sheets


26


can result in a mis-shapened carcass


24


and ball


10


. Conversely, overlapping the sheets


26


by an amount greater than approximately 30 mm leads to an excessive amount of overlapping over the surface of the bladder


12


. However, in alternative embodiments the first sheets


26


can still be overlapped a lesser or greater amount.




In a particularly preferred embodiment, the first lining


14


includes six triple overlapped (or layered) regions


30


wherein one of the triple overlapped regions


30


is positioned on the bladder


12


at the valve


22


and another triple overlapped regions


30


is positioned opposite the valve


22


on the bladder


12


. In alternative preferred embodiments, alternative numbers, and configurations, of first sheets


26


can be used to form the first lining


14


.




Referring to

FIG. 4

in another alternative configuration of the first lining


14


is shown wherein the first lining


14


is comprised of eighteen first sheets


26


arranged in a pattern resembling a conventional volleyball cover. In a particularly preferred embodiment, a generally circular patch


32


is placed around the valve


22


.




Once the first sheets


26


are applied to the bladder


12


, the carcass


24


is placed in a mold and molded under heat while the bladder


12


is pressurized. The carcass


24


is thereafter molded in a cooled mold. The first lining


14


is adhered to the bladder


12


by the latex adhesive. The bladder pressure is reduced to approximately 1 psi. to hold the shape of the carcass


24


while awaiting the next step in the manufacturing process.




Referring to

FIGS. 5 and 6

, the carcass


24


is then deflated and inserted into the elastomeric layer


16


through an opening


34


within the elastomeric layer


16


. The elastomeric layer


16


is preferably a one-piece, integral pouch, or bladder, sized to receive, and substantially surround, the carcass


24


. The elastomeric layer


16


is made of a resilient, flexible material, preferably latex rubber. Alternatively, the elastomeric layer


16


can be formed from any suitable elastomeric material. The elastomeric layer


16


provides the ball


10


with a softer feel and improves the performance of the ball


10


during use by providing a layer of cushionable material to the ball


10


. The elastomeric layer


16


is not attached to the first lining


14


and, therefore, can move relative to the first lining


14


during use. In an alternative preferred embodiment, a powder or a release agent can be applied between the carcass


24


and the elastomeric layer


16


to facilitate relative movement between the elastomeric layer


16


and the first lining


14


. However, the elastomeric layer


16


can move relative to the carcass


24


during use, without the use of the powder or the release agent. In an alternative embodiment, the layer


16


can be made of two or more sections attached together to form the layer


16


. In another alternative embodiment, the layer


16


can be made of a non-elastomeric material.




Referring to

FIG. 7

, the second lining


18


is shown substantially covering the elastomeric layer


16


. Prior to installing the second lining


18


, another patch


32


can be applied to the elastomeric layer


16


around the valve


22


to cover the opening


34


of the elastomeric layer


16


. The second lining


18


is preferably formed from a plurality of second sheets


36


. The second lining


18


and the second sheets


36


are substantially similar to the first lining


14


and the first sheets


26


. Each second sheet


36


typically includes an adhesive for attaching the second sheet


36


to adjacent second sheets, and/or to one or both of the elastomeric layer


16


and the cover


20


. In a preferred embodiment, each second sheet


36


is a layer of adhesive-impregnated cloth. In a particularly preferred embodiment, each second sheet


36


is a 60% polyester and 40% cotton cloth, which was immersed, in latex adhesive.




In a preferred embodiment, the second lining


18


is comprised of twelve or eighteen second sheets


36


. A portion of each sheet


36


preferably overlaps, or is overlapped by at least one other second sheet


36


, such that the elastomeric layer


16


is substantially covered by the load bearing second sheets


36


. When fully applied to the second lining


18


includes a plurality of double and triple overlapped (or layered) sections


38


and


40


. The double overlapped sections


38


occur where a portion of one second sheet


36


overlaps a portion of one other second sheet


36


. The triple overlapped regions


40


occur where a portion of three separate second sheets


36


overlap each other. The second sheets


36


preferably overlap one or more other second sheet(s)


36


by approximately 10 to 30 mm. In a particularly preferred embodiment, the second sheets


36


overlap each other by approximately 20 mm. Alternatively, the second sheets


36


can be overlapped a lesser or greater amount. In alternative preferred embodiments, alternative numbers, and configurations, of second sheets


36


can be used to form the second lining


18


.




The carcass


24


and the elastomeric layer


16


are inflated through the valve


22


and the second sheets


36


are applied to the elastomeric layer


16


. In a preferred embodiment, the second lining


18


includes eighteen sheets which are arranged about the elastomeric layer


16


in a manner which resembles the outer cover panels of a conventional volleyball.




Preferably the second lining


18


is sufficiently shifted with respect to the first lining


14


such that none of the triple-overlapped (or layered) sections


40


of the second lining


18


are aligned with, positioned over, or overlapped with the triple-overlapped regions


30


of the first lining


14


. In other words, at no point about the ball


10


do the combined layers of the first and second linings


14


and


18


reach six or more layers. In one preferred embodiment, the second lining


18


is shifted with respect to the first lining


14


such that the first and second linings


18


, collectively, do not exceed four layers at any point on the ball


10


. The triple overlapped regions


40


, preferably numbering six, of the second lining


18


are preferably shifted and positioned over single layer portions of the first lining


14


. In this configuration, the thickest or stiffest portions of the second lining


18


(the triple layered portions


40


) are positioned over the thinnest most flexible portions (single layered portions of the first lining


14


) of the first lining


14


.




In an alternative preferred embodiment, the second lining


18


is shifted with respect to the first lining


14


such that the first and second linings


14


and


18


, collectively, do not exceed five layers at any point on the ball


10


. In a particularly preferred embodiment, less than five percent of the surface area of the bladder


12


includes five layers of the first and second linings


14


and


18


, collectively.




Further, the second lining


18


is preferably shifted with respect to the first lining


14


such that overlapping of the double-overlapped sections


38


of the second lining


18


with the double-overlapped regions


28


of the first lining


14


is significantly reduced. In alternative preferred embodiments, the second lining


18


can be orientated or shifted in an alternative manner to reduce, minimize or eliminate overlapping of the double and triple overlapped sections


38


and


40


of the second lining


18


with the double and triple overlapped regions


28


and


30


of the first lining


14


. For example, referring to

FIGS. 4 and 7

, in another preferred embodiment, the second lining


18


can be applied to the elastomeric layer


16


in a manner that is rotationally shifted relative to the first lining


14


about at least one axis extending through the ball


10


. In one particularly preferred embodiment, the axis indicated at


42


extends through the ball


10


at the valve


22


, and the second lining


18


is rotationally shifted with respect to the first lining


14


by at least 10 degrees about the axis


42


. In alternative preferred embodiments, the second lining


18


can be shifted about a different axis extending through the ball


10


or multiple axes.




In another preferred embodiment, the first and second linings


14


and


18


are shifted with respect to each other in the following manner. One of the first sheets


26


of the first lining


14


is positioned about the valve


22


in a first position relative to the axis


42


. The remaining first sheets


26


are applied to the ball


10


in a manner generally resembling the outer cover panel pattern of conventional volleyballs. The elastomeric layer


16


is applied over the first lining


14


. Then, one of the second sheets


36


is placed onto the elastomeric layer


16


over, or about, the valve


22


in a second position with respect to the axis


42


. The remaining second sheets


36


are then placed about, and substantially cover, the elastomeric layer


16


to also produce a pattern resembling the outer cover panel pattern of conventional volleyballs. The second position is preferably rotationally shifted by at least 20 degrees relative to the first position. In alternative embodiments, alternative numbers of sheets and configurations of sheets can be used, such as, for example, eight sheets corresponding to the eight panels of a conventional basketball.




By eliminating overlap or alignment of the triple-overlapped sections


40


with the triple-overlapped regions


30


, the volleyball


10


takes a truer shape and the occurrence of mis-shapened or otherwise defective balls during manufacturing is reduced. Also, the existence of stiff, dead, or hard spots about the volleyball


10


are significantly reduced or eliminated thereby improving the feel and response of the ball during use. Further, the reduction of overlapping or alignment of the double-overlapped sections


38


with the double-overlapped regions


28


further improves the shape, ease of manufacture, feel and performance of the ball


10


. Moreover, the shifting of the second lining


18


relative to the first lining


14


does not add to the manufacturing cost of the ball


10


.




During manufacture, the latex adhesive of the second lining


18


is allowed to dry for about two hours, and the product is then hot molded and cold molded as previously described for the carcass


24


. The pressure is then reduced to approximately 2 psi., and the weight, balance, size, and air leakage of the ball


10


are tested. Two coats of latex glue can then be brushed onto the second lining


18


, allowing 20-30 minutes to pass between coats. The latex glue is preferably different than the latex adhesive, which was used to impregnate the first and second linings


14


ad


18


. The product is then molded for approximately 30-40 seconds under room temperature to mold lamination lines on the second lining


18


for positioning a plurality of cover panels


44


which form a cover


20


. The bladder


12


is pressurized at approximately 3 kg/cm


2


during this molding step.




Two coats of latex glue are then applied to the inside surfaces of the cover panels


44


, and the cover panels


20


are applied to the second lining


18


to form the cover


20


. The cover panels


44


may be formed from leather, synthetic leather, rubber, or any other conventional cover material. A volleyball conventionally includes eighteen cover panels


44


.




The ball


10


then undergoes a final shaping/molding step at approximately 40-45 degrees C. and a pressure of approximately 2-4 kg/cm


2


. The molding time is 3 minutes for leather-covered balls and 5 minutes for synthetic leather-covered balls.




Referring to

FIG. 8

, a completed volleyball


10


in accordance with the present invention is illustrated. Referring to

FIG. 9

, the layers of the volleyball


10


are illustrated. The second lining


18


separates the cover


20


from the elastomeric layer and the carcass


24


, which is formed by the bladder


12


and the first lining


14


. The elastomeric layer


16


is not attached to the carcass


24


enabling the elastomeric layer


16


, the second lining


18


and the cover


20


to move freely relative to the carcass


24


. Volleyballs, which are formed in accordance with the invention, are faster and bounce higher than competitive volleyballs. When the ball impacts a player's hand, the cover can move relative to the carcass enabling the ball to stay in contact with the player's hand longer.




Referring to

FIG. 10

, in an alternative preferred embodiment, the volleyball


10


can also include a layer of windings


46


, preferably disposed between the bladder


12


and the first lining


14


. The layer of windings


14


includes one or more elongate threads, which are wound around the bladder


12


to form the layer of windings


14


. The layer of windings


46


further reinforces the bladder


12


and further retains the spherical shape of the bladder


12


. The threads are preferably formed of a high tensile strength material, such as nylon. In alternative embodiments, the thread can be a textile, a wire, or other conventional thread material.




In another alternative embodiment, the volleyball


10


can be formed without the elastomeric layer


16


and configured such that the second lining


18


is movable relative to the first lining


14


.
