A moving carrier comprises a bottom frame assembly, a first support member and a link assembly. A first end portion of the first support member is connected with the bottom frame assembly. The link assembly includes a link member, a first connect member, a second connect member, and two adapter members. The link member is disposed at a second end portion of the first support member. The first connect member and the second connect member are disposed on the link member and connected to the second end portion through the link member. The adapter members are disposed corresponding to ends of the first connect member and the second connect member, and each adapter member has an adapter portion. In the process of changing positions of the first connect member and the second connect member relative to the link member, the adapter portions are oriented to the same direction.

A child safety seat, such as a car seat, booster seat, stroller seat, or high chair, can include a crotch buckle positioner that provides adjustability for the harness system as the child grows. The seat can include a seat bottom, a seat back, a harness system, and a crotch belt positioner. Crotch belt webbing, including a buckle, can extend up through a portion of the crotch belt positioner and is adjusted by the crotch belt positioner. The crotch belt positioner can be adjusted into multiple positions along the seat bottom. Adjusting the crotch belt positioner from a first position to a second position can adjust at least one of the length of the crotch belt webbing that extends about the top surface of the seat bottom and the position that the relational position that the crotch belt webbing extends up through crotch belt positioner with respect to the seat bottom.

A transportation device includes a handle a rear leg, a front leg, a seat, a fixing member, a first seat linkage member and a second seat linkage member. The front leg is pivotally connected to the rear leg. The seat is pivotally connected to the front leg. The fixing member is disposed at a rear side of the seat and connected to an end of the handle. The first seat linkage member is pivotally connected to the seat and the fixing member. The second seat linkage member is pivotally connected to the seat and the rear leg. When the handle, the rear leg and the front leg are folded with respect to each other, the fixing member and the rear leg drive the rear side of the seat to rotate toward a direction opposite to the ground by the first seat linkage member and the second seat linkage member respectively.

A folding frame which serves as basis for a stroller base to allow the interconnection of a child safety seat thereto, while allowing the installation of the child safety seat to a vehicle seat without requiring the disconnection of the safety seat from the folding frame. The folding frame extends from a folded configuration to an unfolded configuration for use as a stroller with or without the use of the child safety seat.

A stroller having a folding frame which serves as basis for a stroller which can be used in a seat configuration for the transportation of a child, and which can be alternatively used in a cart configuration wherein the seat-bottom and seat-back are hingedly interconnected and configured to fold out into a cart for transporting goods such as groceries.

A child carrier includes: a seat portion; a buckle movably provided on the seat portion; a backrest portion connected to the seat portion and extending upward, the backrest portion having a plurality of adjustment holes formed therein from bottom to top; and a shoulder strap having a fixed end and a free end, the fixed end being fixed on a rear side of the backrest portion, the free end passing through one of the plurality of adjustment holes and being removably connected to the seat portion.

An adjustment mechanism of nursery equipment includes a string connecting a fixed portion and a movable portion, a reel that is rotatable in both forward and reverse directions and that changes the position or shape of the movable portion by winding up and feeding out the string, a biasing member that biases the reel in such a way that the reel rotates in a winding direction of the string, and a lock member that prohibits rotation of the reel. A biasing force of the biasing member is selected to be smaller than a biasing force with which the movable portion tends to move downward in the vertical direction.

A child seat includes a front guard and a backrest frame respectively connected pivotally with the seat portion about a first and a second pivot axis, and a folding mechanism including a latch pivotally connected with the seat portion about a third pivot axis for locking and unlocking the front guard with respect to the seat portion, and a linking part coupled to the latch and pivotally connected with the backrest frame about a fourth pivot axis. A rotation of the backrest frame from a deployed position toward a collapsed position causes a displacement of the linking part that urges the latch to unlock the front guard. The first, third, second and fourth pivot axes are arranged in that order along a direction from a front to a rear of the seat portion when the backrest frame is in the collapsed position and the front guard in a folded position.

Integrated environmental infant pram, pet mat, and an integrated environmental infant footmuff are disclosed. System apparatus provides programmable heating/cooling functions, real-time monitoring of the temperature of the pram, mat or footmuff, programmable alarm settings, Bluetooth proximity location, wireless and/or Bluetooth connectivity to separate handheld digital devices, weight sensor inputs, a rechargeable battery power supply with recharging/power connectivity, and microprocessor control of heating/cooling, sensory input/output functions, and communication functions. Embodiments of the infant prams are disclosed as original manufactured equipment or an adaptable retrofit assembly. An artificial intelligence component of the programmable heating/cooling method is also disclosed.
