The present invention discloses a flatbed trolley with casters capable of not folding when a handle rotates, which comprises a bearing frame (1), a handle (2), rotary frames (3), wheel carriers (4), and casters (5). The handle (2) is fixed at an upper portion of the bearing frame (1) via a connecting structure. The connecting structure comprises a left joint (14), a right joint (15), a left gear seat (12), a right gear seat (13), and a handle locking mechanism. The handle locking mechanism comprises a cross bar (7), locking blocks (8), connecting bars (9), switches (10), and a spring (11). The cross bar (7) is a hollow tube with an end being supported on the left gear seat (12) and the other end being supported on the right gear seat (13). An end of the cross bar (7) is provided with the locking block (8), wherein the locking block (8) is slidable along an extension direction of the cross bar (7). An end of the locking block (8) is connected to an end of the connecting bar (9), and the other end of the locking block is capable of inserting into the left joint (14) and the left gear seat (12) to lock them. The connecting bar (9) is installed within a hollow part of the cross bar (7), and the other end of the connecting bar is connected to the switch (10). Similarly, the other end of the cross bar (7) has a same structure. The spring (11) is provided between two switches (10), which thereby enables the casters be capable of not folding when the handle rotates.

In some countries, it is a legal requirement for babies, infants and children under a certain age and/or height to be provided with a supplemental car seat when travelling in a vehicle. Furthermore, parents and guardians of children typically make use of a pram to transport a child. However, babies and infants grow quickly and may outgrow conventional car seats and prams within a year or two years. Therefore, a parent or guardian must typically provide several car seats and prams for their child. The present disclosure provides a child car seat system 100 including an infant carrier module 200 that may be releasably docked within a docking module 300 or a wheeled frame 400 to form a car seat and a pram respectively. The infant carrier module 200 may be arranged in an upright position or a lie flat position.

A collapsible child's stroller with a handle frame (30), a front wheel frame (10) and a rear wheel frame (20), mutually connected at a hinge joint (12, 22, 42) for mutual angular displacement between folded and unfolded configurations. The hinge joint has two spaced apart, parallel hinge axes, about which the frames (10, 20, 30) mutually rotate. The stroller is further provided with a locking element (43, 44) moveable between a locked position in which the frames (10, 20, 30) are locked in the unfolded configuration, and an unlocked position allowing the frames (10, 20, 30) to rotate to the folded configuration. The locking element (43, 44) moves in a direction traverse to the parallel hinge axes to better transfer loads between the frames.

The invention relates to a buggy comprising an upper sliding frame and a lower sliding frame to which the front wheels are attached. In the upright driving position of the buggy, viewed in the side view, the upper sliding frame and the lower sliding frame are approximately aligned with one another. There is also a rear frame to which the rear wheels are attached. In the driving position, the buggy, viewed from the side, is oriented at an angle to the sliding frames, and the buggy can be collapsed about joints from the driving position into a transport position. Joint units, to which the respective end of a strut of the upper sliding frame facing the joint units and the respective end of a strut of the rear frame facing the joint units, are attached so as to be pivotable about joint axes, which are parallel to one another.

A hand trolley includes a trolley main body and a handle assembly. The handle assembly includes a handle, a fastener, and an elastic member. The handle is displaced relative to the trolley main body between a folded position and an unfolded position. The fastener is pivotally connected to the handle. The elastic member is connected with the handle and the fastener to provide an elastic force for the fastener to be located at a predetermined fastening position. When the handle is displaced relative to the trolley main body toward the unfolded position, the fastener is pivoted to engage with an engaging portion of the trolley main body.

A foldable golf trolley includes a standing tube assembly movably coupled with a front wheel assembly through a front wheel connecting rod. A bottom tube assembly is connected with the front wheel assembly and the standing tube assembly. A four-rod linkage is formed by the standing tube assembly, the front wheel connecting rod, the front wheel assembly and the bottom tube assembly. The standing tube assembly is connected with the left and right wheel assemblies through a left and right wheel connecting rod assembly respectively. The left/right wheel connecting rod assembly includes a left/right wheel driving connecting rod and a left/right wheel driven connecting rod, and a left/right wheel four-rod linkage is formed by the left/right wheel driving connecting rod, the left/right wheel assembly, the left/right wheel driven connecting rod and the bottom tube assembly. The trolley could be quickly folded into a compact structure and unfolded.

A stroller frame includes a handle assembly, a front leg assembly and a rear leg assembly having rotating end hubs which are pivotably connected to each other about a hub axis to be rotated so as to allow the stroller frame to transform between folded and unfolded states. A tray mounting assembly is coupled with a tray, is rotatably mounted on one of two rotating end hubs, and is rotated along with the relative rotation of the end hubs to convert the tray to folded and unfolded positions. A tray latching assembly is disposed to retain and support the traymounting assembly to keep the tray stable in the unfolded position when the stroller frame is in the unfolded state.

A bearing structure includes a wheel assembly defining a first front wheel assembly and a second rear wheel assembly, the rear wheel assembly including at least two wheels spaced by a first width defining a first position; wheel supports connecting the axes of rotation of the wheels with the bearing structure; a first folding device enabling a first folding causing a reduction in spacing between the two rear wheels to a second width lower than the first width, defining a second position. A connection system, connecting the wheel supports of the first and second assemblies to the first folding device, enables a second folding of the wheels so as to allow a rotation substantially equal to 90 of the wheels in the horizontal plane when the wheels are in the second position.

A foldable wagon is provided that is configurable in a use configuration and folded configuration. The foldable wagon has a front frame assembly, a rear frame assembly, a first upper pivot bracket and a first lower pivot bracket connecting the front frame assembly to the rear frame assembly. The wagon has a timing member to maintain the front and rear frame assemblies synched during folding and unfolding of the wagon. The wagon also has a footrest with a first end connected to the rear frame assembly and a second end free from connection to the front frame assembly. When the second end of the footrest is raised the rear frame assembly and the front frame assembly pivot from the use configuration to the folded configuration. The wagon also has foldable front and rear seatbacks.

A cart may include a first set of lower support arms and a second set of lower support arms, each of the lower support arms having a wheel attached thereto; a first set of upper support arms and a second set of upper support arms; a holding frame coupled to the first set of upper support arms and the second set of upper support arms; a locking mechanism; and a folding mechanism configured to allow the cart to transition between a folded position and unfolded position. During transition, the first set of upper support arms may be moveable relative to the second set of upper support arms; the first set of lower support arms may be moveable relative to the second set of lower support arms; and the first set of upper support arms may be moveable relative to the first set of lower support arms.
