Abstract: A locking device for a stroller includes a stem member disposed on a front wheel frame of the stroller. The stem member has a reduced intermediate portion with a radial locking hole. A coupling member is disposed to interconnect right and left ends of a connecting frame of the stroller, and is sleeved on and is turnable relative to the stem member. A lateral mount member has one end disposed on the coupling member, and a through hole communicated with the stem member and aligned with the locking hole when the coupling member is turned relative to the stem member to a lockable position. A locking member has a spindle portion disposed in the through hole, and includes an actuated end and a latch portion extendable into and retractable from the locking hole.

Abstract: A step stool or ladder has a first frame member and a second frame member. The second frame member folds to a position within the confines of the first frame member to provide a thin, easily stored ladder for use within a household. The first frame member includes a safety hoop at which the user can easily grab while on the step or rung of the ladder or step stool. The frame also includes a cross member which spans a portion of one of the frame members. The ladder or step stool has one or more steps. At least one of the steps is supported primarily by the cross member in its unfolded position in which a user can ascend on the steps of the stool or ladder. One or more other steps may be attached to step which is primarily supported by the cross member. The step that is primarily supported by the cross member includes a latch that has a first curved end which engages the cross member to prevent the step primarily supported by the cross member from disengaging the cross member.

Abstract: A brake device for braking a stroller, which has an axle and a wheel mounted rotatably thereon, includes a support post secured relative to and extending uprightly from the rear axle, and a mounting frame disposed on the support post and extending beyond the uppermost part of the wheel. The mounting frame includes two lug portions extending in a first direction transverse to the support post and towards the wheel. The lug portions are spaced apart from each other in a second direction transverse to the first direction. A brake shoe includes a pair of arresting portions with two anchoring ends which are mounted pivotally on the lug portions, respectively. The arresting portions extend in the first direction, are spaced apart from each other in the second direction, and form two arresting surfaces therebeneath. A biasing spring has a biasing action along a lengthwise axis, and two ends fixedly secured relative to the support post and to the brake shoe, respectively.

Abstract: A bicycle trailer includes a looped carrier frame and two pairs of vertical sleeves which extend upward from front and rear end portions of the carrier frame. The sleeves have surrounding walls of U-shaped horizontal cross-section, thereby forming vertical openings in the surrounding walls. Each surrounding wall is provided with two opposing horizontally aligned holes. A plurality of horizontal pivot members extend through the aligned holes substantially in parallel with a line that extends from the front end portion to the rear end portion of the carrier frame. Each of a pair of curved support rods has two end portions which are inserted respectively into one of the sleeves of the front end portion and one of the sleeves of the rear end portion.

Abstract: A foldable frame includes a pair of upright supporting rods, a pair of prop members, upper and lower crosspieces, right and left linking arms, and a pair of guiding members. The supporting rods are parallel to each other and extend in a first longitudinal direction. The prop members are also parallel to each other but extend in a second longitudinal direction. Each prop member has a second upper connecting portion pivotally connected to a first upper connecting portion of a respective supporting rod to enable the supporting rods to move from a folded position to a straddling position. The crosspieces are disposed transverse to the supporting rods, and are pivotally mounted thereon. The linking arms have upper and lower end portions respectively pivoted to rear sides of the upper and lower crosspieces, and are spaced apart from each other in a transverse direction, and are parallel to the supporting rods.

Abstract: A separable tandem bicycle includes a front bicycle frame, a rear bicycle frame, and a connecting member which interconnects a front seat tube of the front bicycle frame and a down tube of the rear bicycle frame. The connecting member is detachable from the front seat tube and is foldable over the down tube. A handle bar is detachably mounted to the connecting member. Due to the separable and foldable construction, the tandem bicycle can be put in a package with a reduced size and can be easily stored or transported conveniently.

Abstract: A bicycle trailer includes a frame with front and rear pivot seats, and a sunshade support provided with a foldable unit consisting of a vertical lower rod, a vertical upper rod and a curved rod. The lower rod has a bottom end connected pivotally to the rear seat and an upper end connected pivotally to the upper rod. The curved rod has a front end connected pivotally to the front seat and a rear end connected pivotally to a top end of the upper rod. A bracing element is mounted movably on the lower rod and capable of bracing the upper and lower rods together such that the upper and lower rods are immobilized to each other in a parallel manner. When depressed and pushed frontwardly of the frame, the bracing element permits folding action of the lower rod onto the frame, the upper rod onto the lower rod, and the curved rod onto the upper rod.

Abstract: A foldable stroller includes a seat frame unit, a horizontal wheel frame and a locking pin. The seat frame has a U-shaped lower end portion and a plate member formed with a through hole and connected to the lower end portion. The seat frame unit is supported inclinedly on the wheel frame in an unfolded position and is laid on the wheel frame in a folded position by means of a support frame unit. The front section of the wheel frame has a transverse socket unit so that the U-shaped lower end portion of the seat frame unit can be inserted into the socket unit. The socket unit has a receiving groove and a tubular member which is communicated with the receiving groove. The locking pin extends slidably into the tubular member through the through hole of the plate member of the seat frame unit in order to lock releasably the seat frame unit on the wheel frame in the unfolded position.

Abstract: A bicycle includes a first bicycle body, a connecting frame and a second bicycle body. The first bicycle body includes a vertical seat post for mounting a seat, and a first joint member provided on the seat post. The connecting frame extends longitudinally and rearwardly from the first bicycle body, and has a front end with a second joint member to be releasably connected to the first joint member, and a rear forked end with a pair of separate first connecting portions. The second bicycle body includes a top tube and a bottom tube, both of which respectively have ends forming second connecting portions. The second connecting portions are respectively connected to the first connecting portions. The first connecting portions are fastened to the second connecting portions.

Abstract: A bicycle trailer includes a carrier frame, two wheels provided on two sides of the carrier frame, and a connecting device which is adapted to couple with a frame body of the bicycle. The carrier frame has two pairs of vertical stubs extending upward therefrom in such a manner that one pair of stubs are respectively located on two sides of the front end portion while the other pair of stubs are respectively located on two sides of the rear end portion, and a seat secured to a lower surface of the front end portion of the carrier frame. The connecting device includes a connecting rod pivoted to the seat and rotatable about a horizontal axis, and a coupler unit attached on a front end section of the connecting rod. The coupler unit includes a vertical inner plate adapted to be disposed on one side of the frame body and abutting against a seat stay and a chain stay of the frame body, and a vertical outer plate disposed on the other side of the frame body and abutting against the seat stay and the chain stay.
