A weight-lifting or exercising device wherein the spacing of the weights along the length of the bar and the masses of the individual weights may be selectively varied to accommodate people of different sizes and capabilities. Each of the weights is substantially hollow and includes a generally ovoid or egg-shaped shell. Each shell has a first axis, a central aperture transverse to the first axis, and a tubular member aligned with the axis and extending across the aperture. A channel opens at one longitudinal end of the shell and extends along the axis and through the tubular member for telescopically receiving the bar therein. The aperture is adapted to receive a person's hand or foot to operatively engage the tubular member for exercising purposes and the weights may be used without the bar as individual dumbbells. The shells may be telescoped along the bar and selectively locked at spaced locations along its length. The shells also include compartments which can be filled or emptied of foreign materials such as water, sand, shot or the like to selectively increase or decrease the mass of the individual weights.
An exercising device adapted for being held in one hand comprising a generally egg-shaped housing having a longitudinal axis and having a central aperture extending through said housing in a direction normal to said longitudinal axis, said aperture being adapted to receive said hand therein, an elongated tubular handle portion interior to said egg-shaped housing and being provided with inner and outer cylindrical surfaces, said handle portion extending from one end of said housing across said aperture to the other end of said housing, said tubular handle portion having an axis which is aligned with said longitudinal axis, said handle portion being adapted to be gripably engaged by said received hand, said housing and said handle portion comprising a single unitary piece, said housing including compartments on both sides of said aperture which are adapted to receive foreign materials for increasing the mass of the deivce, the portion of said handle portion adjacent said central aperture of said housing being provided with a plurality of longitudinally spaced openings which extend through the inner and outer cylindrical surfaces thereof, said openings permitting the exercising device to be adjustably connected to a weight lifting bar.
An individual barbell device comprising a generally spherical shell having a first axis and having a central aperture extending through said shell in a direction normal to said first axis, an elongated tubular cylindrical element within the interior space of said shell and being provided with inner and outer cylindrical surfaces, said cylindrical element extending from one side of said shell across said aperture to the opposite side of said shell, said cylindrical element having an axis which is aligned with said first mentioned axis, said shell and said cylindrical element comprising a single unitary piece of molded plastic material, said shell including compartments within the interior space thereof on both sides of said aperture which are adapted to retainably receive mass-increasing foreign matter, the portion of said cylindrical element adjacent said central aperture of said shell being provided with a plurality of openings which extend through the inner and outer cylindrical surfaces thereof, said openings permitting the individual barbell device to be adjustably connected to a weight lifting bar.
A weight exercising device wherein the spacing of the weights may be selectively varied to accommodate people of different sizes and capabilities, said device comprising:
An exercising device wherein both the longitudinal spacing of the weights along an elongated bar and the masses of the individual weights may be selectively adjusted to accommodate people of different sizes and capabilities, said exercising device comprising:
