BACKGROUND OF THE INVENTION

[0002] 1. The Field of the Invention

[0003] The present disclosure generally concerns weightlifting exercise equipment. More specifically, the present disclosure concerns exercise weight bars that vibrate.

[0004] 2. The Relevant Technology

[0005] Exercise weight bars including dumbbells and barbells are well known in the art and are widely used as part of weight-based exercise training. For example, U.S. patent application Ser. No. 12/847,813 titled "Weightlifting Device with Mechanism for Disengaging Weight Plates," which is incorporated herein by this reference, discloses an exercise weight bar. Recent research indicates that creating a vibration in a weight bar while a person is using the weight bar in a training exercise (commonly referred to as "vibration training") can greatly increase the quality of the exercise. Among other benefits, vibration training may increase blood flow, which can speed up recovery from a workout or rehabilitation from an injury. An increase in blood flow may also help to bring restorative nutrients to muscle cells and aid in the removal of metabolic waste from muscle cells.

[0006] Creating a weight bar having a vibration that is sufficiently strong to achieve these benefits can be difficult. For example, the mechanism that creates the desired vibration may be large and interfere with a use of the weight bar. In addition, the weight of the vibration mechanism may create an imbalance in the weight bar. Thus, an improved vibrating weight bar is needed.

BRIEF SUMMARY OF THE INVENTION

[0007] Weight bars of the present invention vibrate in order to provide an enhanced workout. Weight bars of the present invention can be configured to be held by a user in one hand or in both hands. Additionally, the weight bars of the present invention can include a rechargeable power source for the vibration mechanism.

[0008] In one exemplary embodiment, an exercise weight bar can include a handle having a first end, a second end, and a central axis that extends between the first and second ends. A first cavity that is linked to a first end of the handle can at least partially define a first interior space. The first cavity can at least partially enclose battery contacts or a battery. A second cavity that is linked to a second end of the handle can at least partially define a second interior space.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] Weight bars of the present invention vibrate in order to provide an enhanced workout. Weight bars of the present invention can be configured to be held by a user in one hand or in both hands. Additionally, the weight bars of the present invention can include a rechargeable power source for the vibration mechanism.

[0018] In one exemplary embodiment of the present invention, an exercise weight bar can be configured to be held by a user in one hand. One or more cavities can be linked to the handle. The one or more cavities can at least partially enclose a vibration assembly that is configured to create a vibration in the weight bar. A vibration assembly may include a battery, a motor, one or more gears, and an eccentric weight. The battery may be rechargeable and be in electric communication with a charging port. The weight bar can be configured to rest on a base member, which is shaped to receive the weight bar when not in use. The base member can further include a charging plug that mates with the charging port to recharge the battery in the vibration assembly.

[0019] FIG. 1 shows one embodiment of a vibrating weight bar system 100. Vibrating weight bar system 100 can include a weight bar 110 and a base member 180, on which the weight bar can rest while it is not in use. Weight bar 110 includes a handle 114 and a vibration assembly (described in more detail hereafter). and one or more weight plates 140. Handle 114 includes a first cavity 112a, a second cavity 112b, a first weight plate mount 116a and second weight plate mount 116b. These handle portions may be integrally formed as a single unit, or they may be separate components. Handle 114 also includes a longitudinal axis that extends through the handle. The longitudinal axis may be through the center of handle 114 or offset from the center of handle 114. One or more weight plates 140 can be selectively secured to first and second weight plate mounts 116a, 116b.

[0020] One will appreciate that a handle (e.g., 114) can vary in size and shape. In the embodiment illustrated in FIG. 1, handle 114 includes a portion sized to be gripped in one hand of a user. That is, exercise weight bar 110 is configured as a dumbbell with a portion of handle 114 being generally sized in length and circumference to be held by one hand. In other embodiments of the present invention, a handle may be sized to be held by two hands, such as a barbell for use in performing two-handed exercises, such as bench press, curls, etc. Further, an exercise weight bar according to the present invention may be configured as a barbell with a handle that is sized to be held by two hands. One will also appreciate that handle 114 may be bent or curved to accommodate various weight training exercises.

[0021] Handle 114 can also include an outer grip portion 118. Grip 118 can assist in providing a slip-resistant grip for a user during an exercise. For example, grip 118 can include a textured surface or it can be made from a non-slip material, such as rubber or foam.

[0022] A handle can also include one or more cavities. For example, handle 114 includes a first cavity 112a and a second cavity 112b. First and second cavities 112a and 112b can be an integral part of handle 114 or they can be formed separately from, and securely affixed to handle 114. One will appreciate that when first and second cavities 112a and 112b are formed separately from handle 114, first and second cavities 112a and 112b can be mounted, attached, coupled, or otherwise joined together.

[0023] First and second cavities 112a, 112b can have a variety of different shapes and sizes. For example, first and second cavities 112a, 112b can be cylindrical and have rounded outer surfaces. In other embodiments, first and second cavities 112a, 112b can have flat outer surfaces. For example, cavities 112a and 112b may be cube shaped. In addition to shape, first and second cavities 112a and 112b can have a variety of different sizes. The size of first and second cavities 112a and 112b may be determined, in part, by the size of a vibration assembly (discussed in more detail hereafter) that the cavities accommodate.

[0024] In addition, first and second cavities 112a, 112b can, at least partially, define interior spaces (e.g., 120a and 120b). FIG. 2 provides a cross-sectional view of weight bar 110 in which first and second interior spaces 120a and 120b can be seen. In the illustrated embodiment, first cavity 112a defines first interior space 120a and second cavity 112b defines second interior space 120b. First and second interior spaces 120a and 120b can be used to enclose in whole or in part a vibration assembly.

[0025] The vibration assembly illustrated in FIG. 2 includes battery contacts 121, a battery 122, a motor 124, two gears 126 and 128, and an eccentric weight 130. It will be understood by one of ordinary skill in the art that a vibration assembly may include additional or different components from those illustrated in FIG. 2 to create a desired vibration.

[0026] FIG. 2 illustrates that battery 122 is enclosed within first interior space 120a. Battery 122 can be any number of different batteries. For example, battery 122 can be a lithium-ion battery, an alkaline battery, or another type of battery. Battery contacts 121 can be any contacts that are configured to connect to any type of battery. Battery 122 can also be rechargeable. In order to recharge battery 122, the battery can be removed from first cavity 112a and connected to an external recharging device. Alternatively, battery 122 can be configured to be recharged while remaining within first cavity 112a. For example, battery 122 can be in electric communication with a charging port 123. As will be discussed in greater detail below in connection with FIG. 4, charging port 123 can be compatible with any number of different charging plugs.

[0027] In other embodiments, battery 122 may not be rechargeable. In embodiments where the battery is not rechargeable, the cavity that contains the battery can include a door that provides access to the battery so that a user can disconnect the battery from the battery contacts and replace the depleted battery with a new one.

[0028] Second interior space 120b includes a motor 124, a first gear 126, a second gear 128, and an eccentric weight 130. Battery 122 is in electric communication with motor 124 through a wire 132. Wire 132 can pass through a hollow chamber within handle 114 that connects first interior space 120a with second interior space 120b. In alternative embodiments of the present invention, wire 132 can connect battery 122 with motor 124 without passing through handle 114.

[0029] In alternative embodiments of the present invention, different components of a vibration assembly may be contained within different cavities. For example, in one embodiment, battery contacts 121, battery 122 and motor 124 can be contained within a first cavity with gears and an eccentric weight contained within a second cavity, and a shaft extending through the interior of handle 144 to couple motor 124 to the gears and eccentric weight. In another embodiment, each of the components in a vibration assembly may be contained within the same cavity. In such an embodiment, an exercise weight bar may only include a single cavity. In yet another embodiment, weight bar 110 can include two complete vibration assembles (i.e., battery contacts, battery, motor, gears and eccentric weight), with one complete vibration assembly located in the first cavity 112a, a second complete vibration assembly located in the second cavity 112b, and one or more switches electrically coupled to the motors, such that a user can selectively activate only one of the vibration assemblies at a time or selectively activate both vibration assemblies simultaneously. One of the vibration assemblies may also include a control for selectively reversing the direction of rotation of the motor so that the two vibration assemblies can be selectively set to rotate in the same rotational direction or can be selectively set to counter-rotate in opposite rotational directions relative to one another, thereby selectively varying the amplitude of vibration produced.

[0030] FIG. 3 illustrates in greater detail motor 124, first gear 126, second gear 128, and eccentric weight 130. As can be seen in FIG. 3, motor 124 rotates first gear 126 about a first axis 134. First gear 126 engages second gear 128 such that rotation of first gear 126 causes rotation of second gear 128. Second gear 128 rotates about a second axis 136. Second axis of rotation 136 can extend through the middle of handle 114 or it can be offset from the middle of handle 114. Eccentric weight 130 is linked to second gear 128 such that rotation of second gear 128 about second axis 136 causes eccentric weight 130 to also rotate about second axis 136. For example, FIG. 3 illustrates in dashed lines a second position 138 of eccentric weight 130 after a 180 degree rotation from its position in solid lines.

[0031] In order to create a vibration, the eccentric weight can have a center of mass that is offset from the axis about which the eccentric weight rotates. For example, eccentric weight 130 can have a center of mass 140. As eccentric weight 130 rotates, it creates a vibration. The strength and frequency of the vibration can be determined by a number of different variables, including the speed at which the eccentric weight rotates, the distance that the eccentric weight's center of mass is from its axis of rotation, and the size of the eccentric weight.

[0032] In another embodiment of the present invention, an eccentric weight 130 may be linked to and rotated directly by a motor 124 such that first gear 126 and second gear 128 are unnecessary. In this embodiment, eccentric weight 130 would rotate about a first axis 134.

[0033] Weight bar 110 can further include a mechanism to selectively activate the vibration assembly. The mechanism can be a button, switch, or lever. In one embodiment, the vibration assembly may be automatically activated when the weight bar 110 is removed from the base member. In another embodiment, the handle 114 of the weight bar 110 may have contacts that activate the vibration assembly when a user's hand grasps the handle 114.

[0034] Referring back to FIG. 1, handle 114 also includes a first weight plate mount 116a and a second weight plate mount 116b that are configured to receive weight plates 140. First and second weight plate mounts 116a and 116b can be formed as an integral pieces with handle 112 or they can be formed as a separate pieces and later coupled to handle 112 and/or first and second cavities 112a, 112b.

[0035] Weight plates 140 can be removably secured to first and second weight plate mounts 120a and 120b, such that a user can select the amount of weight to place on weight plate mounts 120a and 120b. Weight plates 140 may also be permanently linked to first and second weight plate mounts 120a and 120b. In alternative embodiments, an exercise weight bar 110 may not include weight plate mounts 120a, 120b, or weight plates 140. In these embodiments, no additional weight may be included in the weight bar 110, or additional weight may be included within handle 112, cavities 112a, 112b, or in another part of weight bar 110.

[0036] FIG. 4 provides a perspective view of base member 180. Base member 180 can be shaped such that a weight bar 110 can rest on top of base member 180. For example, base member 180 has a first recess 182a that is shaped to accommodate the shape of a first cavity 112a. Base member 180 also has a second recess 182b that is shaped to accommodate the shape of a second cavity 112b.

[0037] Base member 180 also includes a charging plug 184. Charging plug 184 can be configured to mate with a charging port (e.g., 123) in order to charge a battery (e.g., 122) within a weight bar while the weight bar is resting on the base member 180. The base member 180 can further include a cord (not shown) that plugs into an outlet to provide power to the charging plug 184. In alternative configurations, the charging plug may be separate from the base member such that the weight bar is not required to be resting on the base member in order to recharge the battery.

[0038] It will be understood by one of ordinary skill in the art that the components of the vibrating weight bar system 100 may be formed from any suitable materials. For instance, the weight bar 110 and a base member 180 may be formed of metal, plastic, ceramic, rubber, foams, composite materials, or combinations thereof. Likewise, the components may be formed by any suitable manufacturing processes. Such manufacturing processes may include, but are not limited to, casting, forging, extruding, molding, including blow molding and injection molding, or combinations thereof.
