Abstract: A foldable stroller includes a safety lock for maintaining the stroller in an unfolded use condition. The stroller comprises side frames which are connected together by scissor frames to move the side frames between open use positions and closed folded positions. To maintain the side frames in a spread use position, a two-part spreader bar is provided. A lock in the form of a spring loaded slide on one of the spreader bar parts includes a lock and guide pin which engages a detente in the other spreader bar part to maintain the spreader bar part in an aligned condition. This avoids an inadvertant folding of the stroller. To permit folding of the stroller this slide is pushed to the side disengaging the pin from the detente and permitting the spreader bar parts to be lifted. This allows the side frames to collapse toward each other resulting in the folding of the stroller.

Abstract: A folding wheelchair includes a pair of side frames which are collapsible in their own planes. There is simultaneous collapse of two pairs of strut members. The collapsed wheelchair is very compact, even though the erected wheelchair is very reliable due, at least in part, to its avoidance of areas of high stress concentration. In alternatives, the scissor-like strut members are replaced by fixed struts so that collapse in the height direction is not accompanied by collapse in the width direction.

Said unlocking means comprises a rod, mounted for moving on the chair so as to be able to be brought into a position in which they cooperate with said locking means for unlocking said slide.

Abstract: One end of a support angle member is turnably connected to the lower end of a push rod, and the other end of the support angle member is turnably connected to the middle portion of a rear leg. When the push rod is aligned with one end of the support angle member, a sleeve urged by a spring to slide downward on the push rod engages the opened state locking-purpose engaging portion of the support angle member, thereby locking the opened state of a baby carriage. When the baby carriage is to be locked in its closed state, the sleeve engages the closed state locking-purpose engaging portion of the support angle member, thereby locking the closed state.

Abstract: The invention concerns a trolley comprising a trolley top supportable on a foldable trolley base, for transporting heavy objects particularly between a first support surface and a vehicle and then from the vehicle to a further support surface. The base is foldable between an erected condition in which the sides are spaced apart and upright portions project upwardly from support portions and a folded condition in which the sides are juxtaposed and the upright and support portions lie adjacent one another.In the erected condition a locking pin, at each side, carried by the support portion projects into an aperture in the base of an upright portion to lock the two portions together. When the sides are moved to their juxtaposed positions a release pin attached to the locking pin causes withdrawal of the locking pin from the aperture to allow the upright and support portions to be relatively pivoted to the folded condition.

Abstract: A portable cart for carrying luggage comprises a central section, a handle section detachably connected to a rear portion of the central section, two side sections pivotally connected to the central section respectively and having at least one wheel rotationally connected to a rear portion of the side section, and a device for holding the side sections horizontally so that the upper portions of the side section and the central section are substantially located on the same plane.

Abstract: A structure for connecting a handle to the push rods of a baby carriage is located between the push rods of a pair of push rods (1) and the handle for allowing the widening and narrowing of the distance between the push rods (1) in response to opening or closing the baby carriage. The distance between the push rods (1) in the open state, is firmly maintained in that the connecting sections between the push rods (1) and the push rod-connecting rod (2) are locked. This locking of each connecting section is achieved when a locking sleeve (10) is displaced downwardly by the force of a spring (15), whereas it is canceled when the locking sleeve (10) is displaced upwardly against the force of the spring (15).

Abstract: A baby carriage having a pair of front legs and a pair of rear legs. The pair of rear legs each have an angle bar pivotally connected thereto while the angle bar has a pusher rod pivotally connected to the other end thereof. With the baby carriage in the opened state, the angle bar is substantially in line with the associated pusher rod body. With the baby carriage in the closed state, the pusher bar body and the associated angle bar are in bent relation to each other, thus reducing the vertical dimension of the baby carriage. Further, in response to the turning movement of the angle bars relative to the rear legs, both the longitudinal and the transverse spacings between the front and rear legs are reduced. In this manner, the baby carriage is folded.
