Abstract
A twist-lock button configured to securely fasten two articles together. Such a twist-lock button may have four pieces: a handle, a locking portion, a negative, and a button adapter. The negative attaches to an article by way of the button adapter. The locking portion attaches to the handle and passes through a button hole in the article to join with the negative by twisting 180 degrees, thereby fastening the two portions of the article together between the handle and the negative. This mechanism is more durable than hook and loop fasteners, more reliable than buttons and snaps, and less prone to jamming than zippers. In addition, the twist-lock button is easier to use for people with muscular or motor disabilities, such as cerebral palsy, ALS, stroke recoverees, and amputees.
