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 seat height adjustment mechanism includes a locking bar and a locking element. The locking bar is disposed in a stroller frame and has locking holes spaced apart. Each of the locking holes has a stop portion protruding therein. The locking element is mounted on a seat and has an engaging end. The engaging end is separably engaged in any one of the locking holes and has an engaging hook protruding in a direction, and the direction is crossed with another direction in which the engaging end moves when the engaging end is separating from the locking hole. The engaging hook separably presses against the stop portion. Therefore, the engaging end cannot separate from the locking hole. Even when wrongly operated, the locking element cannot be rotated and unlocked and thereby prevents the seat from unnecessarily sliding downward, so as to ensure safety of a baby at the seat.

A seat includes a support base, an unlock member and a lock member. The support base has at least one through hole. The unlock member is movably disposed on the support base and has at least one first driving portion. The lock member is movably disposed on the unlock member. The lock member has at least one lock portion protruding from a surface of the support base through the at least one through hole and at least one second driving portion abutting against the at least one first driving portion. When the unlock member is forced in a first direction to move, the at least one lock portion is forced to move along the at least one first driving portion through the at least one second driving portion and retracts into the support base in a second direction different from the first direction.

A stroller includes a frame, a handle, a plurality of support legs, a wheel attached to a lower end of each support leg, and a seat attached to the frame. The seat includes an internal Peltier device for selectively heating or cooling the seat. The Peltier device is powered via an onboard battery installed in an electronics housing that includes multiple USB ports. A blanket is removably secured to the seat via one or more fasteners. A processor in the electronics housing performs a method that includes activating the Peltier device to bring the seat to a preset temperature, receiving a temperature setting for the Peltier device from a temperature control button disposed on the handle, detecting a current temperature of an area within the seat, and if the current temperature of the area within the seat is greater than a threshold safe upper temperature, then deactivating the Peltier device.

A stroller has a frame with at least two wheels and a seat unit for supporting a person sitting on it. The seat unit has a seat surface which is designed to be driven movable and/or wherein the seat surface has a plurality of driven movable partial surfaces. A movement pattern of the seat surface and/or the partial surfaces is predetermined in such a way that the back movement of a riding animal is simulated in at least one gait. The seat unit has a kinematic unit for predetermining the movement of the seat surface or the partial surfaces, which is arranged directly below the seat surface or directly below the partial surfaces. Alternatively or additionally, the stroller has a differential connected to at least two wheels so that a combined kinetic energy of these wheels is provided for the movement of the seat surface or the partial surfaces.

A baby carriage includes a handle, a first fixing member, a second fixing member, a rear leg, a front leg, an unlock member, a first lock member, a rotating member and a pulling member. The first lock member engages with the first fixing member and the second fixing member to lock the handle, the rear leg and the front leg at a first unfolded position. When the unlock member pulls the pulling member, the pulling member drives the rotating member to rotate, a first inclined driving surface of the first fixing member pushes the rotating member toward the first lock member, and the rotating member pushes the first lock member toward the second fixing member to disengage the first lock member from the first fixing member.

A foldable stroller for transporting up to two child passengers in a tandem arrangement includes seating configurations that may be easily altered dependent upon the age/size of the passengers. The stroller frame includes an upper seat connector for selectively attaching an upper seat. A lower seat connector is positioned forward of and below the upper seat connector and includes a linkage that allows movement of an associated lower seat between opposing forward and rearward positions without altering the inclination of the lower seat. The forward connector position locates the associated lower seat sufficiently forward to provide clearance for the upper seat and its occupant. When the upper seat is removed, the linkage enables the associated seat to be shifted to the rearward position, shifting the center of gravity location rearward for improved stroller stability.

A connecting mechanism includes a first joint, a second joint, a lock pin, an unlock operating member and a stationary base. The first joint is pivotally connected to the second joint. The lock pin is movably disposed between the first joint and the second joint and configured to lock or unlock the first joint and the second joint. The unlock operating member is connected to the lock pin and configured to drive the lock pin to disengage from the first joint or/and the second joint, so as to unlock the first joint and the second joint. The stationary base is connected to the first joint or the second joint and configured to be detachably connected to a baby carriage.

A child conveyance apparatus includes a child support portion having a canopy mount, a canopy installable on and removable from the child support portion, the canopy including a coupling part that is engaged with the canopy mount when the canopy is installed on the child support portion and disengaged from the canopy mount when the canopy is removed from the child support portion, the coupling part having a plurality of installation positions with respect to the canopy mount that correspond to different heights of the canopy on the child support portion, and a latch provided on one of the canopy mount and the coupling part, the latch being operable to engage with different locations on the other one of the canopy mount and the coupling part for holding the coupling part in the installation positions.

A baby wagon with improved ease of use has a folding structure which is stably configured, and thus damages to frames, such as twisting or bending of the frames, can be prevented, such that the baby wagon is stably folded and unfolded, the use of the baby wagon is convenient while durability of the baby wagon is excellent, and comfort of a baby can be maintained even when the baby is in the baby wagon for a long time. The frames are manufactured so as to be easily folded even in the state in which the canopy is coupled thereto, whereby the baby wagon is unfolded and folded within a short time, such that that portability and mobility of the baby wagon are excellent, and such that detachment and coupling of a canopy and a wheel assembly are easily performed.
