VIBRATING WEIGHT BAR
Weight bars are disclosed that provide an enhanced workout. Specifically, weight bars of the present invention include a vibration mechanism that creates a vibration in the weight bar. Weight bars of the present invention can be configured to be held 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. While not in use, the weight bars of the present invention can rest on a base member. The base member may include a charging plug that mates with the charging port such that the power source for the vibration mechanism can recharge while resting on the base member.
1 . An exercise weight bar comprising:
a handle having a first cavity that at least partially defines a first interior space, a second cavity that at least partially defines a second interior space, and a longitudinal axis;
battery contacts at least partially enclosed within the first cavity;
a motor at least partially enclosed within the second cavity, the motor being in electrical communication with the battery contacts;
an eccentric weight at least partially enclosed within the second cavity, the eccentric weight being rotatably linked to the motor;
wherein the first cavity is shaped to at least partially enclose a battery;
wherein the eccentric weight is rotatable by the motor about the longitudinal axis; and
wherein the eccentric weight has a center of mass that is radially offset from the axis of the handle.
2 . The exercise weight bar of claim 1 wherein the handle further comprises a first weight plate mount and a second weight plate mount.
3 . The exercise weight bar of claim 2 , wherein the first and second weight plate mounts can receive and secure one or more weight plates.
4 . The exercise weight bar of claim 1 further comprising a battery at least partially enclosed within the first cavity.
5 . The exercise weight bar of claim 4 , wherein the battery is rechargeable.
6 . The exercise weight bar of claim 5 further comprising a charging port that is in electric communication with the battery.
7 . The exercise weight bar of claim 6 , wherein the charging port mates with a charging plug that is positioned on a base member.
8 . The exercise weight bar of claim 1 , wherein at least a portion of the surface of the handle comprises a slip resistant grip.
9 . The exercise weight bar of claim 1 , wherein the handle is designed to be gripped in one hand of a user during an exercise.
10 . A weight bar comprising:
a handle having a first cavity at least partially defining a first interior space, and a second cavity at least partially defining a second interior space; and
a vibration assembly comprising:
battery contacts at least partially enclosed within the first cavity;
a motor at least partially enclosed within the second cavity, the motor being in electric communication with the battery contacts;
a first gear at least partially enclosed within the second cavity, the first gear being in mechanical communication with the motor and further being rotatable by the motor about a first axis;
a second gear at least partially enclosed within the second cavity, the second gear being in mechanical communication with the first gear and further being rotatable by the first gear about a second axis, wherein the second axis is generally parallel to and offset from the first axis; and
an eccentric weight at least partially enclosed within the second cavity, the eccentric weight being linked to the second gear, wherein the eccentric weight rotates about the second axis when the second gear is rotated, and wherein the eccentric weight has a center of mass that is radially offset from the second axis.
11 . The exercise weight bar of claim 10 wherein the handle further comprises a first weight plate mount and a second weight plate mount.
12 . The exercise weight bar of claim 11 , wherein the first and second weight plate mounts can receive and secure one or more weight plates.
13 . The exercise weight bar of claim 10 further comprising a battery at least partially enclosed within the first cavity.
14 . The exercise weight bar of claim 13 , wherein the battery is rechargeable.
15 . The exercise weight bar of claim 14 further comprising a charging port that is in electric communication with the battery.
16 . The exercise weight bar of claim 15 , wherein the charging port mates with a charging plug that is positioned on a base member.
17 . A selectively rechargeable vibrating weight bar system comprising:
a weight bar having:
a handle including a first cavity that at least partially defines a first interior space, a second cavity that at least partially defines a second interior space, and a longitudinal axis;
a vibration assembly comprising:
a battery at least partially enclosed within the first cavity;
a charging port in electric communication with the battery such that the battery can be recharged without being removed from the first cavity;
a motor at least partially enclosed within the second cavity, the motor being in electric communication with the battery; and
an eccentric weight at least partially enclosed within the second cavity, the eccentric weight being rotatable by the motor about the longitudinal axis, wherein the eccentric weight has a center of mass that is radially offset from the axis of the handle;
a base member configured to support the weight bar while the weight bar is not being used in a strength training exercise, the base member having a charging plug that is configured to mate with the charging port when the weight bar is resting on the base member such that the battery can be recharged while the weight bar rests on the base member.
18 . The exercise weight bar of claim 17 wherein the handle further comprising a first weight plate mount and a second weight plate mount.
19 . The exercise weight bar of claim 18 , wherein the first and second weight plate mounts can receive one or more weight plates.
20 . The exercise weight bar of claim 17 , wherein at least a portion of the surface of the handle comprises a slip resistant grip.
