The present invention relates generally to an athletic sleeve for carrying items therein, and more particularly to a flexible athletic sleeve for securely carrying fluid containers and other athletic training aids.
Hydration is crucial for an athlete to achieve optimal performance. In many athletic events an athlete may have the option of rehydrating during a break between periods of exertion. For example, a football or basketball player may rehydrate while on the bench waiting to reenter a game. However, an endurance athlete such as a triathlete, runner, or bicyclist typically does not get breaks to rehydrate during an event. Because the event may be several hours long and rest stops, if they exist at all, may be few and far between, the endurance athlete preferably carries a hydration device on their person.
Many types of devices for carrying fluids necessary for hydration exist, for example, waist belts and jerseys that include pockets for holding bottles or a bladder for holding fluid encompassed by a backpack with shoulder straps. However, for an endurance athlete, other considerations beyond hydration are comfort and ease of access. Often, an endurance athlete must push beyond a preconceived limit or substantial physical discomfort to achieve a personal best in physical performance, and to do so requires a heightened level of focus and concentration. An uncomfortable, heavy, hot, difficult to access, or otherwise bothersome device for carrying fluids may diminish the focus of an endurance athlete and thereby detrimentally affect performance.
According to one aspect of the present invention, an athletic training sleeve includes a first piece of elastic material forming a tube of elastic material and a second piece of elastic material attached around a partial periphery thereof to the tube of elastic material to define a pocket therebetween. An opening of the pocket is defined between an unattached edge of the second piece of elastic material and the tube of elastic material. The opening of the pocket has a higher resistance to expansion than does a portion of the pocket.
According to another aspect of the present invention, an athletic training sleeve includes a first piece of elastic material and a second piece of elastic material attached to the first piece of elastic material to form a tube of elastic material. A third piece of elastic material is attached around a partial periphery thereof to the second piece of elastic material to define a pocket therebetween. An opening of the pocket is defined between an unattached edge of the third piece of elastic material and the second piece of elastic material. The unattached edge defining the opening of the pocket has a higher resistance to expansion than does a portion of the pocket and the closed end of the pocket is generally parallel with an end of the tube.

Other aspects and advantages of the present disclosure will become apparent upon consideration of the following detailed description, wherein similar structures have the same reference numerals throughout.
The present invention is directed to an athletic training sleeve that allows an endurance athlete to stay hydrated during exercise. While specific embodiments are discussed herein, it is understood that the present disclosure is to be considered only as an exemplification of the principles of the disclosure. Therefore, the present disclosure is not intended to limit the disclosure to the embodiments illustrated.
Illustrative examples of types of stretchy or elastic material useful herein include spandex, stretchable lace, polyester, nylon, rayon, cotton, polyester blend, and combinations thereof. The elastic materials used in the present invention are preferably lightweight and breathable and may also have very smooth or silky surfaces to add to an athlete's comfort. Further, these materials may also have wicking properties, such that the materials wick moisture away from the skin of an athlete and the moisture evaporates and leaves the material dry and cool and the athlete comfortable. Endurance athletes often use the term of art “technical materials” to refer to materials that are lightweight, breathable, and include wicking properties. Thus, a “technical material” generally describes a material that encompasses all of the desirable properties of materials listed hereinabove, but without reference to the specific type of material or blend of material.
Each type of elastic material includes at least four physical characteristics that are useful in describing the response of a piece of the material to a force applied thereto. The four physical characteristics are: (1) 2-way or 4-way stretchable; (2) stretchability; (3) rest size; and (4) elastic modulus. A fifth physical characteristic that is derived from a combination of the four physical characteristics, as explained further hereinbelow, is the resistance to expansion of the piece of the material.
Each type of elastic material discussed herein may be 2-way stretchable or 4-way stretchable. An elastic material is said to be 2-way stretchable if the material stretches in response to force applied thereto along at least one axis, referred to as an axis of elasticity, within a plane of the elastic material. For example, a 2-way stretchable material may have a vertical axis of elasticity, wherein the material stretches up and down along the vertical axis of elasticity. An elastic material is said to be 4-way stretchable if the material stretches in response to force applied thereto along any two perpendicular axes of elasticity within a plane of the elastic material. Thus, a 4-way stretchable material is also a 2-way stretchable material. For example, a 4-way stretchable material may have a vertical axis of elasticity and a horizontal axis of elasticity, wherein the material stretches up and down along the vertical axis of elasticity and to the left and the right along the horizontal axis of elasticity. Of course, such examples are only for illustrative purposes, it being understood that the axes of elasticity in 2-way or 4-way stretchable materials may be disposed at any point within the materials.
Stretchability along a first axis of a material may be quantified by stretching a piece of elastic material to a maximum extent along the first axis and measuring a stretched size between two points along the first axis. The stretched size is compared to a rest size of the piece of material measured along the first axis between the same two points used to measure the stretched size. This comparison yields a stretchability ratio, which may be expressed as a multiple, for example, the stretched size is 2.03 times the rest size, or as a percentage, for example, the stretched size is 203% of the rest size. A first material is said to have a greater stretchability than a second material if the stretchability ratio of the first material is greater than the stretchability ratio of the second material. For example, if the first material and the second material have identical rest sizes along a particular axis, and the first material has a greater stretchability than the second material, the first material will have a greater maximum stretched size than does the second material. A 4-way stretchable material may have dissimilar stretchability ratios along first and second perpendicular axes of elasticity within a plane of the 4-way stretchable material.
Another characteristic to consider is the rest size of the piece of elastic material. For example, consider two pieces of an identical elastic material of different rest sizes, piece A and piece B. Piece A is a circle of the elastic material with a 10 cm radius and piece B is a circle of the same elastic material with a 15 cm radius. The elastic material has a stretchability ratio of 2.0 such that piece A may be stretched to a maximum radius of 20 cm and piece B may be stretched to a maximum radius of 30 cm. Further, because pieces A and B are made of the identical elastic material, an identical force is necessary to stretch each piece to its maximum extent. Logically, to stretch pieces A and B to less than a maximum extent requires a lesser force than is required to stretch each piece to its maximum extent. Therefore, piece A requires more force to be stretched to 20 cm than piece B requires to be stretched to 20 cm.
Elastic modulus of a material determines the force required to elastically stretch a piece of material a given distance along a particular axis of elasticity. For example, consider two pieces of different 2-way stretchable material of identical rest sizes and stretchabilities, piece C and piece D. Piece C is a circle of a first type of elastic material with a 10 cm radius and a stretchability of 2.0. Piece D is a circle of a second type of elastic material with a 10 cm radius and a stretchability of 2.0. Piece C has a higher elastic modulus along a first axis of elasticity than does piece D along a second axis of elasticity. Therefore, piece C requires more force to be stretched to a radius of 11 cm along the first axis of elasticity than piece D requires to be stretched to a radius of 11 cm along the second axis of elasticity.
The resistance to expansion of a piece of material may be described in light of the four above-described physical characteristics. Generally, the resistance to expansion of a particular piece of material is the force required to stretch the particular piece of material and may be a function of any or all of the direction of stretch relative to an axis of elasticity, stretchability, rest size, and elastic modulus. For example, if a piece of 2-way stretchable elastic material is stretched to a maximum extent along an axis of elasticity, the resistance to expansion of the piece of material along the axis is the tensile strength of the piece of material along the axis. For a piece of 2-way stretchable elastic material, the resistance to expansion perpendicular to an axis of elasticity is the tensile strength of the piece of material perpendicular to the axis. If a first piece of material has a first elastic modulus and a first rest size and a second piece of material has a second higher elastic modulus and the same rest size, the second piece of material requires more force to stretch beyond the rest size and therefore has a greater resistance to expansion than the first piece of material. Finally, if a first piece of material has a first rest size and a second piece of identical material has a second larger rest size and the first and second pieces of material are each stretched to an identical stretched size, the first piece of material requires more force to reach the stretched size and therefore the first piece of material has a greater resistance to expansion at the stretched size.
The resistance to expansion of an opening is the force required to enlarge the cross-sectional area of the opening. Therefore, the resistance to expansion of an opening is a function of the resistance to expansion of the elastic material that defines the opening.

The pocket 118 may be oriented at any angle with respect to a longitudinal extent 126 of a cylindrical wall 127 forming the tube 106. For example, in the embodiment illustrated in
Referring to
Each of the first, second, and third pieces 102, 104, 110 of elastic material may be made of the same or a different type of material as the other of the first, second, and third pieces 102, 104, 110 of elastic material. Further, each of the first, second, and third pieces 102, 104, 110 of elastic material may have the same physical characteristics as or different physical characteristics from the other of the first, second, and third pieces 102, 104, 110 of elastic material. For example, the third piece 110 of elastic material may have a greater stretchability than the first and second 102, 104 pieces of elastic material.
Referring now to
The athletic training sleeve 100 with the item 132 placed within the pocket 118 is slid over the endurance athlete's hand and up a straightened arm thereof. The athletic training sleeve 100 is comfortably positioned around the upper arm 134 over biceps 136 and triceps 138 muscles. Upon positioning of the athletic training sleeve 100 over the biceps 136 and triceps 138 muscles, the unattached edge 120 inhibits the item 132 from being easily removed from the pocket 118. Further, bending of the arm of the endurance athlete accentuates the biceps muscle 136 and may further inhibit the item 132 from being removed from the pocket 118. To access the item 132, the endurance athlete need only straighten his or her arm and slide the athletic training sleeve 100 off of the arm.
The tube 106 may have a diameter that is smaller at the bottom end 128 thereof than at a second or top end 140 thereof, as illustrated in
The athletic training sleeve 100 described hereinabove may be worn over clothing or outerwear for outdoor use in cold weather or may be worn over bare skin for use in excessive heat indoors or outdoors. The elastic material may be made of a silky material as described hereinabove to feel cool against the skin of the endurance athlete. An outer surface of the athletic training sleeve 100 may be coated or otherwise impregnated with a highly reflective material such that the athletic training sleeve 100 may be seen in headlights of vehicles at night. Further, positioning the item 132 on a back side of the upper arm 134 over the triceps muscle 138 and proximate to a shoulder of the athlete minimizes the sensation of carrying extra weight during periods when the upper arm 134 is swinging back and forth and during periods when the upper arm 134 is not swinging.
Another embodiment of an athletic training sleeve 200 is illustrated in
A fourth piece 202 of elastic material is attached to the unattached edge 120 of the third piece 110 of elastic material between ends 207a, 207b of the edges 112, 116 that form the partial periphery of the third piece 110. Still referring to the embodiment of
Still referring to
The fourth piece 202 of elastic material has a greater resistance to expansion than the third piece 110 of elastic material, and the greater resistance to expansion may be achieved in a number of ways. For example, the fourth piece 202 of elastic material may have a greater elastic modulus along a length thereof than the third piece 110 of elastic material along an axis generally parallel to the fourth piece 202. The fourth piece 202 of elastic material may have a lesser stretchability along a length thereof than the third piece 110 of elastic material along an axis generally parallel to the fourth piece 202. Further, the fourth piece 202 of elastic material may be made of the same elastic material as the third piece 110 of elastic material, but may have a smaller rest size along a length thereof than the third piece 110 of elastic material along an axis generally parallel to the fourth piece 202, as illustrated in
