Compressive resistance means and exercise device

摘要

An exercise device (10) is provided with a twist cap (14) spaced apart from a base cap (12) with a resistance assembly (52) therebetween. The resistance assembly (52) includes a spring (20), a rotating member (26) that rotates with the twist cap (14), and a translating member (30) threadably engaged to the rotating member (26) and configured to variably deform the spring (20) due to rotation of the twist cap (14) in order to adjust the resistance level. An annularly pleated sidewall (16) and a vent means (18) may be included to provide a further resistance means. The exerciser compresses the twist cap (14) towards the base cap (12) to experience both compressive and bending resistance.

1. An exercise device, comprising:
a base cap; a twist cap configured to be rotated relative to the base cap; and a resistance assembly interposed between the base cap and the twist cap, comprising:
a rotating member coupled with the twist cap and configured to rotate with the twist cap;a translating member threadably engaged with the rotating member and configured to translate upon rotation of the twist cap; anda spring, having a longitudinal axis, spanning between the translating member and the base cap to form a flexible connection between the base cap and the twist cap, the translation of the translating member changing the deformation of the spring for changing a resistance level; wherein the twist cap is adapted to be rotated to change the resistance level, the base cap and the twist cap are adapted to be pushed together to compress the spring of the resistance assembly, and the base cap and the twist cap are adapted to be torqued relative to each other to bend the spring of the resistance; and wherein a user rotates and bends said device with respect to said longitudinal axis during exercise.
