Compressible barbell adapter
A compressible barbell adapter is disclosed, which consists of a compression-retraction member fastened to a hollow shaft for use on a bar. The compression and retraction movement of the compression-retraction member is generally achieved by means of a pinion and a rack system, and can be utilized in conjunction with dampening means. Slidable handles are also connected to the compression-retraction member, and serve to slide along the axis of the hollow shaft, and thus along the bar. The compressible barbell adapter is meant to be fastened onto existing bars or barbells such that additional exertion is focused on the pectoral, deltoid and back muscles during various exercises.
1. A compressible barbell adapter comprising:
a hollow shaft for receiving a bar;
a compression-retraction member connected to the hollow shaft further comprised of upper and lower racks operatively connected to corresponding upper and lower pinions; and,
slidable handles operatively connected to the compression-retraction member, allowing for the slidable handles to slide along the hollow shaft.
2. The compressible barbell adapter of claim 1 further comprising at least one securing means positioned on the bar.
3. The compression-retraction member of claim 1 further comprising a dampening system connected to the compression-retraction member.
4. The compressible barbell adapter of claim 3 wherein the dampening system has a fixed resistance.
5. The compressible barbell adapter of claim 3 wherein the dampening system has an adjustable resistance.
6. The compressible barbell adapter of claim 1 further comprising upper and lower guiding rails.
7. The compressible barbell adapter of claim 1 further comprising clamping blocks for receiving the shaft.
8. The compressible barbell adapter of claim 1 further comprising an adapter plate with an LED array.
9. The compressible barbell adapter of claim 1 further comprising a cover.
