Abstract
A height-adjustable armrest unit for a chair includes a support, a vertical sleeve, and a leverage body. The support is mounted securely on the seat of the chair and includes a vertical plate portion with a column of positioning holes formed therethrough. The vertical sleeve is disposed on the vertical plate portion of the support and has a pair of pivot holes respectively formed in the inner surfaces of two opposite side walls thereof. The leverage body includes an actuated upper end portion, an engaging tongue projecting from the lower end portion of the leverage body to engage selectively one of the positioning holes, and a pair of pivot pins respectively secured to an intermediate portion of the leverage body between the actuated upper end portion and the engaging tongue so as to engage the pivot holes respectively. Accordingly, when the actuated upper end portion is actuated to disengage the engaging tongue from the positioning hole, the assembly of the leverage body and the vertical sleeve can be moved relative to the support so as to engage the engaging tongue within another one of the positioning holes, thereby adjusting the height of the sleeve.
