Abstract
A hand weight includes a chassis including a handle portion configured to be grasped by a user such that a forearm of the user extends along an axis, and a flexible element attached to the chassis. The hand weight can be configured to receive a movable mass, and the flexible element can be configured to at least partially support the movable mass such that the movable mass forms at least part of a sprung mass of a hand weight assembly including the hand weight and the movable mass, the sprung mass configured to move relative to the chassis of the hand weight and deform the flexible element in response to a force in a direction along the axis applied to the handle portion by the user while grasping the handle portion.
Claims20
A hand weight comprising:
- a body;
- a handle attached to the body and positioned in an opening of the body, the handle configured to be grasped by a user;
- one or more flexible membranes positioned around the body, the one or more flexible membranes being attached to the body;
- and
- one or more cavities positioned around the body and being at least partially defined by the one or more flexible membranes and the body, wherein the one or more cavities are configured to collectively receive a movable mass that is movable within the one or more cavities, the movable mass configured to move relative to the body and cause deformation of the one or more flexible membranes in response to a force applied to the handle by the user while grasping the handle.
A method of using a hand weight graspable by a hand of a user, the method comprising:
- grasping the hand weight at a handle positioned in an opening extending through a central axis of the hand weight, the opening defined by a body of the hand weight;
- applying a force in a first direction along an axis, wherein applying the force in the first direction comprises causing a movable mass to move in a second direction along the axis to deform one or more flexible membranes positioned around the central axis of the hand weight to deform in a second direction along the axis relative to the hand of the user and to shift a center of gravity of the hand weight along the axis in the second direction along the axis relative to the hand of the user;
- and
- applying a torque in a first direction about the axis, wherein applying the torque on the hand weight in the first direction about the axis comprises causing rotation of the movable mass relative to the body of the hand weight in a second direction about the axis.
