A child seat includes a seat portion fixedly connected with a first coupling part, a backrest frame fixedly connected with a second coupling part, the second coupling part being pivotally connected with the first coupling part so that the backrest frame is rotatable relative to the seat portion, a rotary element pivotally connected with the first coupling part, the rotary element being rotatable relative to the seat portion and the backrest frame, and a locking mechanism operatively connected with the backrest frame and operable to rotationally lock and unlock the rotary element with respect to the seat portion. The locking mechanism is configured to switch between a locking state and an unlocking state in response to a rotation of the backrest frame relative to the seat portion and the rotary element.

The invention relates to a field of a transport driven manually, namely, to baby strollers, and it is intended to allow an alternate use of different variants of a baby cradle or seat which differ in a size and in a weight on a frame thereof. A baby stroller having a frame with adjustable width, the frame consists of front wheel supports hingedly connected between each other, rear wheel supports which are equipped with wheel mounting assemblies, and handle supports, comprising a removable seat or cradle fixed on mounting places, wherein horizontal cross-bars are arranged between the supports of the rear wheels and front wheels. According to the invention, the frame consists of two semi-frames, and the horizontal cross-bars are made adjustable in length and arranged on each of the semi-frames so as to be fixable at least in a first frame adjustment position and at least in a second frame adjustment position.

A child stroller apparatus includes a stroller frame and a stroller seat. The stroller seat includes a backrest portion fixedly connected with a first joining part, a seat portion fixedly connected with a second joining part that is pivotally connected with the first joining part, a coupling part pivotally connected with the second joining part at a side thereof opposite to that of the first joining part and adapted to connect with the stroller frame, a latch movable between a locking position engaged with the coupling part and an unlocking position disengaged from the coupling part, and a linking mechanism configured to movably couple the latch to the first joining part so that the backrest portion is rotatable in a folding direction to cause the latch to disengage from the coupling part and in an unfolding direction to cause the latch to engage with the coupling part.

An assembling structure of double stroller comprises a first assembling part, a second assembling part and a third assembling part. The first assembling part comprises a first seat, two first frames, a handle, and a first accommodation region allowed for the first seat to be disposed. The second assembling part comprises a second seat, two second frames, and a plurality of wheels, as well as a second accommodation region allowed for the second seat to be disposed. The third assembling part comprises first connecting parts, each being connected to each of the first frames at one end far away from the handle, and second connecting parts, each being connected to each of the second frames at one end far away from the second seat. Moreover, each of the first frames is inclined with respect to each of the second frames to form an L-shaped installation.

A child stroller apparatus includes a stroller frame, a connecting mount provided on the stroller frame and having a first coupling portion, and an adapter suitable to receive the installation of a detachable component. The adapter is installable on and detachable from the first coupling portion of the connecting mount, and includes a support body having a second and a third coupling portion, the second coupling portion being connectible with the first coupling portion, and the third coupling portion being connectible with a detachable component. The first coupling portion of the connecting mount is adapted to receive the installation of the adapter and a detachable component, and the arrangement of the adapter on the connecting mount allows the installation of a detachable component on the third coupling portion of the adapter at a mount position that differs from a mount position provided by the connecting mount.

A connection mechanism is used for detachably installing a carrier device to a supporting device. The connection mechanism includes a first base, fixed on the supporting device, a second base, fixed on the carrier device and detachably connected to the first base, a latch, movably disposed on the second base and corresponding to the first base, and an operating component, disposed on the second base and operably connected to the latch. The operating component selectively drives the latch to move to a locking position so that the second base is locked to the first base, or drives the latch to move to an unlocking position so that the second base is unlocked from the first base.

A snapping structure is provided, which is configured to detachably mount a body to a support frame. The snapping structure includes a locking member movably disposed on the body and a positioning member disposed on the support frame and mated with the locking member. The locking member is movable to be locked to the positioning member, so as to mount the body to the support frame, or the locking member is movable to be unlocked from the positioning member, so as to separate the body from the support frame.

A carrier mounting (3a, 3b) for supporting an infant carrier on a pushchair chassis, the mounting comprising a socket member having a first socket (17) and a second socket (19) therein, both sockets being configured to receive a correspondingly shaped mounting strut of an infant carrier. The socket member is pivotable between first and second positions such that when the carrier mounting is connected to a pushchair chassis, the first or second socket (17, 19) respectively is locatable in a receiving position in which a longitudinal axis of the respective socket bore is oriented with respect to the pushchair chassis at an angle suitable for receiving a mounting strut of an infant carrier. When the second socket (19) is in its receiving position, said second socket (19) supports the infant carrier at a higher point on the pushchair chassis than the first socket (17). The carrier mounting further comprises a locking mechanism (23) configured to releasably hold the socket member in each of the first and second positions, and to allow pivoting therebetween.

In one example, a carrycot couples to a support frame to support the carrycot above a support surface. The carrycot has a carrycot frame having a first side and a second side that are spaced from one another so as to define a space therebetween that supports a child therein. The carrycot has a set of attachment features that is disposed at the first side and removably attaches to a bayonet of the support frame. The set of attachment features includes (1) a bayonet receptacle that receives a first portion of the bayonet and (2) a plunger that is spaced below the bayonet receptacle with respect to a vertical direction and is configured to engage an opening in a second portion of the bayonet.

A transportation device includes a frame and a carrier. The frame includes a rail, a fixing base, an unlock member and a sliding member. The rail has a first engaging hole with a first retaining wall. The unlock member has an engaging portion. An end of the sliding member abuts against the unlock member. The carrier includes a connecting base with a rib. The connecting base is connected to the fixing base to install the carrier on the frame. When the carrier faces a first direction, the rib pushes the sliding member to push the unlock member, such that a length of the engaging portion protruding from the fixing base is reduced. When the carrier faces a second direction, the rib is staggered with the sliding member.
