The present specification generally relates to support shirts for supporting a wearer such as while performing a powerlifting exercise and, more specifically, support shirts that restrict the wearer's range of motion during a lifting exercise.
Support shirts may be used for supporting a wearer during weightlifting activities. Support shirts can assist in increasing the amount of weight that a wearer can lift by storing energy within the shirt. However, injury can result from flexion of the wearer's arms while bringing a weightlifting bar closer to the wearer's chest. Further, a chest area of traditional support shirts may lift away from the wearer's chest when the wearer's arms are extended, which may be prohibited in powerlifting organizations. Moreover, the elastic material of traditional support shirts stretches unevenly during weightlifting, resulting in a loss of stored energy in the support shirt.
In one embodiment, a support shirt includes a shirt body including a front portion having a top edge and an opposite bottom edge, a pair of sleeves extending outwardly from the front portion, and a restriction panel provided on the front portion between the pair of sleeves and extending from the top edge toward the bottom edge, wherein the sleeves have a sleeve elasticity and the restriction panel has a restriction elasticity less than the sleeve elasticity.
In another embodiment, a support shirt includes a shirt body including a front portion having a top edge, an opposite bottom edge, and a pair of circular seams defining a pair of sleeve openings, a collar provided at the top edge of the front portion of the shirt body, a pair of sleeves extending outwardly from the front portion, the pair of sleeves being fixed to the front portion at the pair of sleeve openings, and a restriction panel provided on the front portion between the pair of sleeves and extending from the top edge toward the bottom edge, the restriction panel being defined by a pair of restriction seams, the pair of restriction seams being parallel to one another and extending from the top edge toward the bottom edge, the pair of restriction seams contacting the pair of circular seams. The pair of sleeves has a sleeve elasticity, the restriction panel has a restriction elasticity less than the sleeve elasticity, and the collar has a collar elasticity less than the sleeve elasticity.
In yet another embodiment, a method of manufacturing a support shirt, the method including forming a shirt body, coupling a restriction panel to the shirt body, and coupling a pair of sleeves to the shirt body on opposite sides of the restriction panel, wherein the pair of sleeves has a sleeve elasticity and the restriction panel has a restriction elasticity less than the sleeve elasticity. Forming the shirt body includes coupling a first panel to a second panel, and coupling the second panel to a third panel.
These and additional features provided by the embodiments described herein will be more fully understood in view of the following detailed description, in conjunction with the drawings.
The embodiments set forth in the drawings are illustrative and exemplary in nature and not intended to limit the subject matter defined by the claims. The following detailed description of the illustrative embodiments can be understood when read in conjunction with the following drawings, where like structure is indicated with like reference numerals and in which:
Embodiments described herein are directed to support shirts that include a pair of sleeves configured to store energy upon movement of a wearer's arms from a raised position to a lowered position in a bench press activity, and a restriction panel configured to restrict the wearer's arms from moving beyond the lowered position. The lowered position is a position that prevents a weightlifting bar from lowering beyond a point at which the weightlifting bar contacts a chest of the wearer when the support shirt is worn and while performing a lifting exercise such as, for example, a bench pressing exercise. It should be appreciated that the support shirts disclosed herein are equally applicable in other exercises such as, for example, a powerlifting activity.
The support shirts described herein generally include a shirt body, a pair of sleeves, and a restriction panel. The shirt body includes a top edge, a front portion, and an opposite back portion, the front portion having a top edge and an opposite bottom edge. The pair of sleeves extend outwardly from the front portion, and the restriction panel is provided on the front portion between the pair of sleeves. The sleeves are formed of a sleeve material and have a sleeve elasticity, and the restriction panel is formed of a restriction material and has a restriction elasticity less than the sleeve elasticity. Various embodiments of the support shirts will be described in more detail herein.
As used herein, “elasticity” refers to the ability of a material to stretch. A material having a higher, or greater, elasticity than another material stretches a further distance than the other material under the same application of force. A material having a lower, or lesser, elasticity than another material stretches a lesser distance than the other material under the same application of force. Specifically, elasticity may be measured in pounds per square inch (psi) or gigapascals (GPa) using Young's modulus or any other suitable unit for measuring elasticity and strain. For example, when a first material has a greater elasticity than a second material, the first material has a Young's modulus lower or less than the Young's modulus of the second material, e.g., the first material has a lower psi and GPa measurement than the second material. Alternatively, when the first material has a lower elasticity than the second material, the first material has a Young's modulus higher or greater than the Young's modulus of the second material, e.g., the first material has a higher psi and GPa measurement than the second material. As referred to herein, the elasticity and Young's modulus of a material is measured by an overall elasticity of the material, rather than any particular portion or region of the material. As such, the elasticity and Young's modulus of the material is generally the same regardless of a direction in which tension is applied on the material.

The sleeves 14 are formed from a sleeve material that provides support to the arms of the wearer during use. In embodiments, the sleeve material has a sleeve elasticity greater than the body elasticity.
In embodiments, the sleeve material is formed of a knee wrap material. In some embodiments, the sleeve material is a woven or non-woven fabric material that includes elastic strands extending therethrough. In some embodiments, the fabric is formed of at least one of nylon, cotton, and polyester. In embodiments, the sleeve material is the same as the body material, where the sleeve material is thicker than the body material. In other embodiments, the sleeve material is different than the body material, where the sleeve material has an elasticity less than the body material. Specifically, the sleeve material may have a Young's modulus that is greater than the Young's modulus of the body material. In other embodiments, the sleeve material has a sleeve elasticity equal to the body elasticity.
The pair of sleeves 14 may each include a compression member 56 (shown in
The compression member 56 may be formed of a compressible material, such as neoprene, rubber, cotton, polyester, and the like, and may include inner springs, gel, an air pocket, a fluid pocket, and the like. The compression member 56 may compress when the sleeves 14 bend, such as during the descent of a pressing movement. The compression of the compression member 56 prevents the sleeves 14 from bunching around the arms of a wearer, thereby preventing restriction of blood flow to the arms of the wearer. The compression member 56 may store energy when compressed, such that the compression member 56 assists the wearer in extending the wearer's arms.

As shown in
In embodiments, the second panel 32 and the third panel 34 may be discontinuous members such that the second panel 32 and the third panel 34 do not extend across the entire back portion 22 of the shirt body 12 between the pair of sleeves 14. As such, the back portion 22 of the shirt body 12 may expose the back of the torso of the wearer when the support shirt 10 is worn. In this embodiment, the opposite sides of the back portion 22 may be secured to one another by fasteners extending from opposite sides of one or more of the second panel 32 and the third panel 34. The fasteners may include at least one of hook and loop fasteners, straps, ties, buttons, magnets, or any other well-known known fastener. As a non-limiting example, the fasteners may be one or more straps extending from one or more sides of the second panel 32 and/or the third panel 34 to wrap around the torso of the wearer to secure opposite sides of the second panel 32 and/or the third panel 34 to one another.
As discussed herein, the support shirt 10 provides support to the wearer when the wearer's arms are in a raised or extended position and a lowered or retracted position. In use, the wearer's arms are fully extended outwards from the wearer's torso when in the extended position. When in the retracted position, the wearer's elbows are positioned closer to the front portion 20 than in the extended position, with the wearer's elbows bent and positioned in substantially a same plane as the torso.
When the support shirt 10 is worn by the wearer, the sleeves 14 provide support to the arms, biasing the arms toward the extended position. When the arms are moved from the extended position to the retracted position, the sleeves 14 are stretched by the bending of the arms, thereby increasing a biasing force provided by the sleeve elasticity of the sleeve material. Additionally, during movement of the arms from the extended position to the retracted position, the restriction panel 18 inhibits the arms of the wearer from extending beyond the retracted position. Specifically, as the restriction panel 18 is formed of the restriction material that has the restriction elasticity that is less than the sleeve elasticity, the restriction panel 18 restricts the stretching of the sleeves 14 beyond the retracted position. The inhibiting of the movement of the arms of the wearer from extending beyond the retracted position prevents the arms of the wearer from extending beyond a point at which the weightlifting bar contacts the chest of the wearer. Specifically, upon further movement of the arms beyond the retracted position, the amount of downward movement of the weightlifting bar and consequently an amount of distance the weightlifting bar must be moved to reach the extended position is reduced.
The compression member 56 in each of the sleeves 14 compresses when the arms are in the retracted position, thereby preventing bunching of the sleeves 14. Additionally, the compression member 56 stores energy to assist the wearer in moving the arms from the retracted position to the extended position. Further, when in the retracted position, the weightlifting bar may be resting on the protective pad 50. The protective pad 50 distributes the weight of the weightlifting bar across the torso of the wearer. Additionally, the protective pad 50 may be compressed by the weightlifting bar, thereby storing energy in a manner similar to the compression members 56 to assist the wearer when moving from the retracted position to the extended position.
When the wearer's arms are in the retracted position, a concentration of stress is located at an upper part of the front portion 20 near the collar 16. In some embodiments, the collar 16 may also inhibit movement of the sleeves 14 beyond the lowered position due to the collar 16 being formed of the collar material that has the collar elasticity that is less than the sleeve elasticity and/or the restriction elasticity, such that the collar 16 inhibits the support shirt 10 from tearing at the stress concentration area when under stress from the arms in the retracted position. In some embodiments, the restriction panel 18 cooperates with the collar 16 to prevent tearing at the stress concentration area when under stress from the arms in the retracted position. In some embodiments, the restriction panel 18 and the collar 16 are formed as a one-piece, monolithic structure.
When the wearer's arms extend from the retracted position toward the extended position, the stretched material (e.g. the concentration of stress) provides a biasing force on the wearer's arms, biasing the wearer's arms toward the extended position. The biasing force assists the wearer in bench pressing a greater amount of weight. The protective pad 50 and compression members 56 additionally provide a biasing force on the wearer's arms to assist the wearer in moving toward the extend position.

In some embodiments, the sleeve material extends between the sleeve openings 42 defined by the circular seams 26, where the restriction panel 18′ overlays the sleeve material. Specifically, a portion of the front portion 20 disposed between the openings of the sleeves 14, through which the arms of the wearer extend, is formed of the sleeve material having the sleeve elasticity. As the restriction panel 18′ overlays the portion of the front portion 20 disposed between the sleeve openings 42 of the sleeves 14, the restriction panel 18′ inhibits the movement of the sleeves 14 and the arms of the wearer beyond the retracted position. In some embodiments, the portion of the front portion 20 disposed between the sleeve openings 42 of the sleeves 14 is formed of the restriction panel 18′ without the sleeve material.
Referring now to
From the above, it is to be appreciated that defined herein are support shirts including a shirt body, a pair of sleeves, and a restriction panel wherein the sleeves are formed of a sleeve material and have a sleeve elasticity, and the restriction panel is formed of a restriction material and has a restriction elasticity less than the sleeve elasticity. As such, the pair of sleeves are configured to store energy upon movement of a wearer's arms from a raised position to a lowered position, and the restriction panel is configured to restrict the wearer's arms from moving beyond the lowered position.
