A stroller mainly includes an upper rack, a front wheel rack, a rear wheel rack, an arched rib, a connection bar, a bracing bar, a guarding handle, a plurality of rotary joints and a plurality of corresponding bars. It also has a folding means consisting of the rear wheel rack, arched rib, second, third and fourth rotary joints, a direction switch and wheel retraction means consisting of the front wheel rack, arched rib, second, third and fourth rotary joints, a brake means consisting of brake pulling bar assembly, a plurality of brake means and a cable, and a seat assembly consisting of a cross coupling hub, a guarding handle, a seat rack and a first rotary joint. The second rotary joint is slidable on the rear wheel rack. The fourth rotary joint is slidable on the arched rib.

A collapsible stroller frame capable of being either collapsed or expanded with a rod set, wherein a slide sleeve is located at a front supporter of the stroller frame and a foldable supporter is pivotally connected between the front supporter and a rear supporter. A link rod connects the slide sleeve and the foldable supporter, and is pivotally connected between the front and rear supporter. The foldable supporter includes a front folding tube and a rear folding tube, pivotally connected to each other. A user can operate the foldable supporter to shorten the distance between the front and rear folding tubes, by disengaging the slide sleeve from the frame, thereby facilitating assembly and folding of the stroller.

A baby stroller for transporting an infant at speeds faster than normal walking is disclosed. This baby stroller can be folded to make it easier to stow and transport. The folding mechanism, a unique feature of the design is directed toward compactness, ease of use, reliability, and reduction in manufacturing costs.

A transportable utility carrier apparatus for coupling to a transport vehicle, including an upper frame, a recessed platform connected to the upper frame, a wheeled base, a lift system interposed between the base and the upper frame for moving the wheeled base relative to the platform between a transport position and a freestanding position, a square hitch tube connected to the upper frame, and a rollered receiver hitch mountable to the transport vehicle. The wheels are spaced from the ground in the transport position. The square hitch tube is receivable within the rollered receiver hitch and the rollered receiver hitch eases insertion of the square hitch tube thereinto to prevent binding on unleveled ground.

The snowmobile having a longitudinal axis, a chassis, a pair of skis each having a steering spindle, and a suspension system. The suspension system comprises, for each ski, a first control arm pivotally mounted to the chassis for pivotal movement about a first pivot axis and having a first pivotal connection to the spindle and a second control arm pivotally mounted to the chassis for pivotal movement about a second pivot axis and having a second pivotal connection to the spindle spaced from the first connection. The pivot axis of each control arm and the connection of that control arm to the spindle define a control arm plane; the control arm planes intersect to define a control line that intersects a vertical plane containing said longitudinal axis.

A medical cart is described and includes a work platform having a work surface and at least one compartment, a base, and a height adjustment mechanism for adjusting the height of the work platform relative to the base. A medication module is described and includes a plurality of compartments. The medical cart can be joined with a medication module. In addition, a plurality of medication modules can joined to form a train. The medical cart and medication module can be used collectively and individually in a variety of methods for transferring medicine.

This invention provides a structured luggage system that allows for maximum versatility in luggage piece dimensions and using two luggage pieces. Each of the two luggage pieces can be converted from a full-height luggage piece to an approximately half-height piece with relative ease. The lower or main piece includes conventional wheels and a retractable/extendible handle for easy transport. The upper or secondary piece is adapted to stack on and be secured to the extended handle and (in full-height configuration) offer a secondary grip for added stability adjacent to the handle grip. The lower piece includes an inner central septum that can be sealed or opened to selectively define either a two-compartment piece or large, single compartment piece. Each compartment includes easily removable stiffeners in corresponding side pockets. By removing the upper compartment stiffeners, the pocket can be collapsed into a thickened top that includes the septum as the thickened top's inside face. By also removing the bottom set of stiffeners, the bottom compartment can be collapsed, allowing the entire main/lower piece to be compressed for easy storage.

A contact configuration between boot and binding for snowboarding. Contact pins are provided on opposing sides of the boot at both the heel area and the toe area. This 4-point contact configuration assures heel and toe stability and reliable side boot restraint. Concave mating receptacles at matching locations on the binding assure easy and simple interconnection which is also secure and reliable. A release mechanism is provided to selectively retract the pins using a simple pull cord arrangement. Strap linkages permit more convenient tightening and loosening of the boot straps. A strap/yoke configuration provides improved interconnection between the boot and the user's foot. The pull cord is routed within the sole of the boot and upward along the ankle area of the boot for more convenient access. The pull cord is connected to retract linkages at both heel and toe areas, both of those linkages being spring loaded to provide normally extended pins. A variety of pin receptacle configurations are shown for facilitating boot-to-binding step-in connection.

A ladder strap (150) is made by joining—for example, by co-molding—a first, relatively supple material, defining a lower strap portion (155) with a second, relatively hard material defining an upper strap portion (165). The teeth (167) of the ladder strap are comprises substantially of the harder, second material. In a preferred embodiment, the first and second materials are thermoplastic urethanes, and the co-molding is done using an injection molding process. The co-molding process may be accomplished with co-injection, wherein the two materials are injected at about the same time, or the first material may be injected into a first mold cavity and allowed to partially set, after which the cavity is modified to accommodate the second material.

A pneumatic locking swivel caster comprises a swivel caster and a locking device which may be activated by fluid pressure. The swivel caster may be a dual wheel swivel caster. An improved theatrical prop or scenery element comprises a pneumatic locking swivel caster and a control system. The control system may comprise a tank filled with pressurized air and a control valve. A pneumatic locking swivel caster may be locked into position by activating the control valve and pressuring the caster with air. The pneumatic locking swivel caster may comprise a triple swivel caster adapted such that all three sets of wheels are locked by air pressure.

A collapsible side wheeled walker accommodates a user walking to one side of the walker while holding the walker and supporting at least a portion of the user's weight on the walker. The walker can be collapsed in a tripod-like manner into a compact configuration that is easily transported and stowed.
