Portable rebounding device with force adjustment assembly

A rebounding device comprising:

• a front member:
• a rear member;
• and
• a spring mechanism including a first biasing element and a force adjustment assembly, wherein the force adjustment assembly includes:
• a spring element including a front planar surface and a rear planar surface connected at a rounded portion, wherein the front planar surface contacts an inner surface of the front member:
• a screw housing secured to an inner surface of the rear member, wherein the screw housing includes a channel and a bore on an upper surface:
• a drive screw positioned through the bore and along the channel of the screw housing, wherein the drive screw includes first and second bearings positioned at first and second ends of the drive screw and a knob secured to the first end of the drive screw through a threaded screw;
• and
• a threaded block positioned within the channel of the screw housing, wherein the threaded block engages the drive screw and is configured to move vertically along the channel, and wherein the rear planar surface of the spring element is secured to the threaded block.

A rebounding device comprising:

• a front member;
• a rear member;
• and
• a spring mechanism including a first spring element, a second spring element, and a force adjustment assembly, wherein the force adjustment assembly includes:
• a third spring element including a front planar surface and a rear planar surface connected at a rounded portion, wherein the front planar surface contacts an inner surface of the front member;
• a screw housing secured to an inner surface of the rear member, wherein the screw housing includes a longitudinal channel and a bore on an upper surface;
• a drive screw positioned through the bore and along the longitudinal channel of the screw housing;
• a threaded block positioned within the longitudinal channel of the screw housing, wherein the threaded block is configured to move vertically along the longitudinal channel, and wherein the rear planar surface of at least one spring element is secured to the threaded block;
• a screw housing cover including a bore, the screw housing cover being positioned on an upper base portion of the screw housing so that the bore is aligned with the longitudinal channel;
• wherein movement of the spring element is along the longitudinal channel of the screw housing.
