Abstract

A reclinable office chair includes a reclination adjustment unit coupled to a bottom base disposed at the bottom of the office chair and having an angle limiting element disposed below and spaced apart from a connecting element abutting against carrying elements. When a user sitting on the office chair tilts the office chair in a predetermined direction, the connecting element and the carrying elements, whose movement is restricted by a rim of the bottom base, are stopped from tilting further as soon as the angle limiting element tilts to an extent to come into contact with the rim, not only allowing the office chair in operation to be tilted within a predetermined safety range in any direction, but also enhancing the anti-slip effect which takes place between the office chair and the floor.

Abstract

A reclinable office chair includes a reclination adjustment unit disposed at the bottom of the office chair. The reclination adjustment unit balances itself on the floor properly, resiliently and steadily. The office chair tilted in a forward-backward direction and/or a left-right direction displays directional stability relative to the floor in a manner not to lose the directional stability even when a sitter tilts in any direction, thereby allowing the office chair to provide a comfortable seat for the sitter to sit on, regardless of whether the office chair is upright or tilted in any direction.

Abstract

A storage rack for use as a storage element on the underside of a folding table is fixed to a predetermined portion of the underside of the table and has a foldable configuration. The storage rack can be folded along with the table and can be unfolded into a horizontal state along with the table in order for the table to store an object on the storage rack.

Abstract

A desk structure with adjustable angles is provided, characterized in that: an angle-adjustment unit is coupled to a bottom of a desk which is space-demanding and falls into the category of OA office furniture such that folding the desk entails: performing positional release with the angle-adjustment unit disposed below a desk board, rotating the desk board by a predetermined inclination angle, and imposing a positional restriction on the angle-adjustment unit upon completion of the angular positioning of a rotation state. Accordingly, the desks can be folded up each by a predetermined adjustable inclination angle and stacked up in a non-space-demanding direction.

Abstract

A height-adjustable handrest has constituent components describe below. A middle bar element is inserted into a handrest external bar and has an internal space for containing a spring and an inner bar element. The handrest external bar is enclosed by a support unit with an upper end pivotally coupled to a press element. The press element has one end abutting against the inner bar element and has the other end protruding under an upward thrust from the spring. A pin passing through slots formed at the handrest external bar to penetrate oblong holes disposed at the inner bar element and the middle bar element, respectively. When pressed, the press element drives the inner bar element to move downward, thereby moving the pin upward along the inclined oblong hole of the inner bar element, compressing the spring downward, and moving the pin into a longitudinal channel of the handrest external bar.

Abstract

A foldable seat structure includes a front foot part and a horizontal pole of a height across the front foot part engaged with a rear foot part. A first forward extending part and a second forward extending part are mounted on a horizontal pole of the rear foot part, to be jointed with a corresponding holding part of the front foot part. A screw is used to restrict the joint position. The front foot part is further jointed to a back frame with a back pad and a chair cushion on a front of the rear foot part. The screw of the holding part and the first and second forward extending parts can be unlocked to facilitate the rear foot part to be cross-folding with the front foot part to greatly reduce size for the package to be sold.
