Abstract

A wheeled cart includes a number of unique methods to synchronously stow all of the rear wheels of a fold flat, compact wheeled cart device without removing any of the wheels themselves and the innovations are applicable to cargo carriers, golf bag carts, trolleys, baby strollers, and other devices for moving cargo. In alternative designs, the folding motion of either the forward wheel frame, or the swiveling motion of the rear wheel frame, or both, synchronously setup or stow the cart's at least two rear wheels to achieve an ultra-thin stowed profile, orienting all the cart's wheels in a co-planar stowed relationship, closely parallel with all other parts.

Abstract

A baby stroller foldable joint includes a joint mechanism having a top frame joint, a bottom frame joint and a rear wheel frame joint connecting to the top frame, the bottom frame and the rear wheel frame respectively. Each frame joint is provided with a breach at its rim, and the breaches are aligned with one another. The joint mechanism has a gear set in its interior. A control mechanism has a slider flexible to move back and forth, driving a flexible block through a linkage, for the purpose of clasping or separating the breaches of the frame joints, to accomplish expansion or folding of the frame. By aforesaid combination, expansion or folding of the frame can be simultaneous and accomplished at one go, and expansion can even be locked automatically, to make the manipulation handy and swift.

Abstract

A golf bag cart front wheel foldable device includes a fixed mount, a movable mount and a front wheel frame. The fixed mount has one end connected to the bottom tube of the cart frame and the other end provided with a fitted end. The fitted end is in pinned connection with a buckle at its one side. The movable mount is capable of being seized by the buckle and is joined fixedly to the fixed mount by a hinge. The movable mount has one end provided with a fitted end which is physically in harmony with the fixed mount. The front wheel frame has a top end connected fixedly to the movable mount, while its bottom end is joined to the front wheel. Through loosening of the buckle, the movable mount is not seized, which enables the movable mount and the front wheel frame to rotate with respect to the hinge, and the front wheel is then leveled for folding purposes, to achieve great handiness in maneuvering.

Abstract

A golf bag cart foldable device includes a bottom cart stand having a link segment at its top, where both sides of the link segment each is in pinned connection with a rear wheel frame, which has its bottom end join the rear wheel, and the bottom cart stand is provided with a slider at the bottom of the link segment. An upper cart stand is in pinned connection with the link segment at its bottom, and has a bracket at its top, where the bracket couples to a mount at its one end. A handle bar is joined the mount at its bottom at which an angle adjustable joint is located, and has a score board at its top. A linkage set comprises a first linkage being set up between the upper cart stand and the slider, a second linkage being set up between the slider and the rear wheel frame, and a third linkage being set up between the mount and the first linkage. Through the linking of the linkage set, the angles between the upper cart stand and the handle bar and between the bottom cart stand and the rear wheel frame will change for the folding or fixing of the device.

Abstract

A golf cart collapsible device includes a frame folding articulation, a linking mechanism, a four-bar linkages mechanism, a front wheel, two rear wheels and a locking mechanism. Thus, the front wheel and the rear wheels are folded and expanded simultaneously by driving the upper frame, so that the golf cart is folded and expanded easily, quickly and conveniently. In addition, the front wheel and the rear wheels can be folded and expanded simultaneously, so that the user needs not to hunker or bend his/her body to fold and expand the front wheel individually, thereby greatly facilitating the user folding and expanding the golf cart.

Abstract

A front wheel foldable device for a golf cart includes a main body, a wheel frame, a positioning member, a sleeve, a stop member, and an elastic member. Thus, the wheel frame is pulled outwardly relative to the main body so that the locking portions of the positioning member are moved to detach from the locking grooves of the main body respectively. Then, the wheel frame is rotated through ninety (90) degrees and is released, so that the post of the wheel frame is retracted into the main body by a restoring force of the elastic member, the locking portions are locked in the locking grooves respectively, the front wheel is turned from an upright state to a horizontal state, and the front wheel is parallel with and rested on the cart frame when the cart frame is folded.

• B62B 3/00 - Hand carts having more than one axis carrying transport wheels; Steering devices therefor; Equipment therefor

Abstract

An articulation includes a first shell, a second shell, a gear wheel, a push button, and an elastic member. Thus, the second shell is unlocked from the first shell by pressing the push button so that the second shell is rotatable freely relative to the first shell so as to adjust the angle between the second shell and the first shell. In addition, when each of the limit plates of the gear wheel is separated from a respective limit slot of the second shell, the gear wheel is stopped by the second shell and is not pushed by the elastic member, so that the second shell is rotatable freely relative to the first shell through a larger angle without having to press the push button successively, thereby facilitating a user adjusting the angle in an energy-saving manner.

• E05D 11/10 - Devices for preventing movement between relatively-movable hinge parts

Abstract

A stroller includes a main frame, a pedal, a front wheel frame, and a positioning device. The positioning device includes a lower cover, an upper cover, a rotation knob, and a locking rod. Thus, the front wheel frame is locked to and unlocked from the main frame by moving the drive plate of the rotation knob, so that the positioning device is operated easily and rapidly. In addition, when the positioning device is unlocked, a click sound is produced so as to notify the user that the positioning device is unlocked and the front wheel frame is rotatable relative to the main frame freely, thereby facilitating the user judging the state (locked or unlocked) of the front wheel frame.

• B62B 9/12 - Perambulator bodies; Equipment therefor involving parts that are adjustable, attachable or detachable

Abstract

A golf cart front-wheel collapsing device includes two parallel lower tubes, two stationary annular gears, a rotary cylindrical gear, a switch and a front wheel. The lower tubes are fixed under a golf cart frame, having a lower end combined with each stationary annular gear, with the cylindrical gear located between the stationary annular gears, and with a coil spring located respectively between each stationary annular gear and the cylindrical gear. The switch is positioned in one of the stationary gears for securing other components in place and operated to engage and disengage the stationary gears with and from the cylindrical gear, letting the front wheel removably combined with the cylindrical gear able to be expanded or folded for collapsing this device, also adjusting the front-wheel's angle to suit to users of different heights.

Abstract

An adjustable front fork blade for a stroller includes a sleeve, a base movably mounted in the sleeve, and a connecting tube mounted between the sleeve and the base. Thus, the front fork blade has an adjustable length so that when two front fork blades are mounted on a front wheel, the length of each of the two front fork blades can be adjusted to match each other so as to calibrate and center the position of the front wheel, thereby preventing the front wheel from being oscillated or vibrated due to deflection.
