Abstract: A quick release structure for front wheels of baby strollers includes an upper mount disposed on one leg support thereof. A fixing pin is arranged on the upper mount for inserting into a locking hole on the leg support. Moreover, a lower mount assembled with a wheel is set on the bottom of the upper mount. A connection rod at the top of the lower mount is inserted into the upper mount. A fixing groove for locking with the fixing pin is formed around the side wall close to the top of the connection rod. A positioning slot is provided on the bottom of the upper mount for mounting a L-shaped positioning rod pivoted on the lower mount. Thus the stroller can keep moving forward without changes in directions by pressing the positioning rod to be locked into the positioning slot for the purposes of easy assembling, storage and transportation.

Abstract: A base member for swivel caster comprises a fixed base, a rotation base and a hollow staff. The fixed base includes a ring member, and a plurality of first raceways lathed in an inward surface of the ring member. A support cavity is defined through a center of the rotation base. Assembling holes are defined in a connecting portion and communicate with the support cavity and the second raceways. During assembly, a plurality of rolling balls are extended through the assembling holes and loaded into the first raceways and the second raceways. Then a plurality of biasing balls is loaded into the assembling holes. The staff is inserted into the support cavity and blocks the assembling holes. The rolling balls contact the biasing balls instead of fixed components whereby the rolling balls swivel and rotate smoothly.

Abstract: The caster leg assembly has a slidable collar mounted on a shank that is threaded onto a stud fixed within a hollow table leg. A resiliently deformable ring is positioned between a shoulder on the shank and an inwardly turned end of the leg. A locking nut is threaded onto a threaded portion of the collar to abut the inwardly turned end of the leg. After the shank has been adjusted along the length of the stud, the locking nut is threaded against the end of the leg to cause the collar to be drawn in a direction out of the leg thereby compressively deforming the ring to frictionally engage the collar and leg. This, in turn, locks the shank against rotation relative to the leg.

Abstract: A wheel of a rack consists of a wheel support, a sleeve inserted into a tube of a rack, a supporting member joined to both the sleeve and a top of the wheel support, and a screw projecting from the supporting member and screwed into the sleeve; a step-shaped portion being formed on top of the supporting member to fit with a cavity on the sleeve bottom; a resilient C-shaped ring being fitted around an annular groove of the sleeve to contact an inner side of the tube; the groove being shaped so that a sideways facing portion thereof tapers off towards a lower end; thus, the ring will move to the bigger upper section of the sideways facing annular portion to be pressed against the inner side of the tube with bigger pressure when a downward force is applied on the sleeve.

Abstract: A chair base includes a rigid base member having a plurality of elongate tubular leg members disposed angularly around and radiating outwardly from a central hub. Each leg member adjacent an outer free end thereof has a hub structure defining a through vertical bore for retaining the pintle of a caster. The hub structure includes coaxially aligned upper and lower sleevelike hub parts which are monolithically and integrally joined to and extruded transversely into the interior of the leg member from the respective top and bottom walls thereof. The pintle-retaining hub structure is formed by a pierce-and-extrude process whereby small pilot openings are initially formed through the respective walls, and the annular wall portion surrounding the respective pilot opening is thereafter transversely extruded to effect forming of the respective hub part. The pierce-and-extrude process for each hub part is, in a preferred process, carried out by a single forming tool.
