The at least two elements of the baby carriage being connected at an articulated joint, so as to be pivotable relative to one another, coupled together in a rotatably fixed manner so as to not be pivotable to one another. The lateral articulated joints being configured to be selectively released and selectively fixed, whereby to permit selective pivoting of some elements of the baby carriage relative to other elements of the baby carriage.

Disclosed is a stroller chassis with a hub. The stroller chassis comprises a first frame assembly and a second frame assembly. The hub is configured to couple the first frame assembly to the second frame assembly pivotably about a pivot axis and releasably lockably with respect to each other. The hub is configured to detachably and lockably support a carrying structure on the chassis. The hub is configured to support the carrying structure relative to the chassis pivotably about the pivot axis and lockably in a rotational position. Also disclosed is a stroller chassis with a hub. The hub is configured to detachably and lockably support a carrying structure on the chassis. The hub is configured such that fully unlocking the carrying structure from said hub to allow detachment may be caused by operation of only one release member.

The present disclosure provides a baby stroller frame, comprising: a front leg rod, a front wheel connected to a lower end of the front leg rod; a rear leg rod, a rear wheel connected to a lower end of the rear leg rod, an upper end of the front leg rod being rotatably connected with an upper end of the rear leg rod; a handle set comprising a rear link rod, the rear link rod is rotatably connected to the rear leg rod at a position that is on the rear link rod and is close to an lower end of the rear link rod; a front support rod comprising a first link rod and a second rod slidably connected to the first link rod, the first link rod being rotatably connected to the upper end of the rear leg rod or to the upper end of the front leg rod, the second link rod being rotatably connected to the rear link rod; a seat rod having one end rotatably connected to the rear link rod and one other end rotatably connected to a middle portion of the front leg rod; the stroller frame according to the present disclosure is provided with an easy folding mechanism that allows for a quick folding configured to realize one-click quick folding and automatically standing, thereby enabling convenient operations of taking away and putting down, meanwhile reducing the production cost and improving the user experience.

A collapsible stroller frame assembly which is selectively configurable in an unfolded configuration for carrying a child or infant, and a folded configuration for compact storage or transport in a vehicle, the frame assembly comprising: a front wheel frame with a front wheel assembly; a rear wheel frame with a rear wheel assembly; a lower hinge connecting the front wheel frame to the rear wheel frame in articulated manner, a seat frame hingedly connected to the lower hinge; an upper hinge connected to the seat frame at a position spaced from the lower hinge; a handle frame connected to the upper hinge, a manual release for user actuation; and a mechanical link between the upper and lower hinges; wherein the lower hinge is lockable to hold the seat frame, the front wheel frame and the rear wheel frame in the unfolded configuration, and unlockable to allow relative rotation of the seat frame, the front wheel frame and the rear wheel frame into the folded configuration; and the upper hinge is lockable to hold the handle frame and the seat frame in the unfolded configuration, and unlockable to allow rotation of the handle frame relative to the seat frame into the folded configuration; such that, user actuation of the manual release unlocks the upper hinge for rotation of the handle frame relative to the seat frame, and the mechanical link unlocks the lower hinge in response to a predetermined angular rotation of the handle frame relative to the seat frame.

A secure package delivery system comprises a lockable container configured for securement to a movable door or exterior wall of a building structure. The container includes a walled body and openable lid. A vertically and horizontally adjustable dolly handle assembly is slideably coupled to a rear of the body and operable to form an adjustable gap for receiving a portion of the door to trap and secure the container in place. The handle assembly is lockable in place to the container and in vertical position by a crank mechanism operated via a lever. The container further includes a movable securement aperture in the handle assembly and wall pin which permits securing the container to a wall via operation of handle assembly and crank mechanism. A movable latch operated by the crank mechanism secures the wall pin in the securement aperture to prevent removal of the container.

Provided are a stroller frame and a stroller. A first rotating shaft and a second rotating shaft are provided at intervals on a stroller folding mechanism of the stroller frame, which is hinged to a handle assembly through the first rotating shaft, and is hinged to one end of a handrail assembly through the second rotating shaft; the handle assembly is hinged to a rear foot assembly through a third rotating shaft, the rear foot assembly is provided with a fourth rotating shaft, and one end of the handrail assembly and one end of a front foot assembly are both hinged to the rear foot assembly through the fourth rotating shaft; and the seat assembly has one side hinged to the handle assembly through a fifth rotating shaft and the other side hinged to the front foot assembly through a sixth rotating shaft.

In one example, a carriage for pushing a child carrier has a wheeled frame that transitions between expanded and folded configurations. The frame has first and second leg assemblies and first and second linkages. The first leg assembly has a first front leg and a first rear leg that are pivotably coupled to one another. The second leg assembly has a second front leg and a second rear leg that are pivotably coupled to one another. The first linkage is attached to the first front leg and the first rear leg, and the second linkage is attached to the second front leg and the second rear leg so as to guide movement of the front and rear legs as the frame is transitioned between the expanded and folded configurations. The first and second linkages each define a support surface that supports an underside of the child carrier.

A foldable golf cart includes an upper frame, a lower frame, a handlebar set, a front wheel set, and two rear wheel sets,. The upper frame is mounted on the lower frame. The front wheel set is mounted at a front end of the lower frame. The rear wheel sets are rotatably mounted on the left side and the right side of the rear end of the lower frame respectively. The handlebar set is connected with the upper frame through a first lock mechanism, the upper frame is connected with the lower frame through a second lock mechanism, and the first lock mechanism and the second lock mechanism are connected through a link mechanism. When the first lock mechanism is unlocked, the handlebar set is rotated, and at this moment, the link mechanism drives the second lock mechanism to be unlocked.

A cart including a body that has a frame and a caster, and the frame including first and second bars. The cart further includes a basket, first and second couplers attached to the basket such that the first and second couplers removably couple in a snug fit with either the first and second bars respectively, or the second and first bars respectively. The cart further includes first and second latches attached to the basket such that the first and second latches are constructed to reversibly secure the first and second couplers respectively to either the first bar and the second bar, or the second bar and the first bar, and a latch-connecting means having a first end attached to the first latch and a second end attached to the second latch such that the latch-connecting means permits the second latch to be controlled by the first latch.
