About This Invention
A clean example of a mechanical utility patent on a fitness product. The invention is an isolation bar that sits below the grasping region of a chin-up or pull-up bar; the user presses their forearms against it while performing the exercise, isolating the targeted muscle groups and improving form. The bar can hang from the pull-up bar on straps or mount to a door frame, wall, or free-standing frame. We later obtained a second, continuation patent for this client on the same invention — US 12,447,376 (issued October 21, 2025) — broadening the protection.
Abstract
An isolation bar for a chin-up or pull-up bar extends parallel or at an acute angle (angled facing upwards) and is below a grasping region of the chin-up or pull-up device. The isolation bar can be hung from the chin-up or pull-up bar by way of cables/elongated straps or be fixed to a door frame, wall mounted, or free standing device with the grasping region. In use, the forearms of a user are pushed against the isolation bar while carrying out a chin-up or pull-up.
Representative Claim

1. A pull-up exercise device with an isolation bar, comprising:
two spaced apart grasping regions held in place relative to the ground;
said isolation bar;
said isolation bar with a contact region at an acute angle relative to a horizontal line extending between said two spaced apart said grasping regions, said isolation bar between said two spaced apart grasping regions and said ground; and
wherein wheels on a side of said isolation bar opposite said contact region are adapted to be pressed against a fixed vertical structure, and rotation of said wheels causes an angle change of said contact region.
