It relates to a child car seat, and more particularly, to a child car seat equipped with wheels and a handle, which facilitates the guiding of the car seat with a single hand, in such a way that the child is rearward to the direction of the movement, facing the person guiding the car seat.

A cart comprises a body structure and at least one wheel connecting structure. The body structure comprises a support shaft, a first frame member and a second frame member. Both the first and second frame members are disposed on the support shaft. The wheel connecting structure is disposed on one end of the support shaft and comprises a driving assembly, a rotating assembly, a linking assembly, and an energy assembly. The driving assembly is connected to the first frame member. One end of the rotating assembly is disposed in correspondence with the one end of the support shaft, and the other end of the rotating assembly is mounted on a wheel member. The linking assembly is disposed between the driving assembly and the rotating assembly. The linking assembly comprises a pushing unit, which is pivotally connected to the rotating assembly. The energy assembly is connected to the linking assembly.

A portable storage device that includes a storage body comprising a plurality of sides enclosing a space suitable for storing items therein, and a wheel assembly coupled to the storage body suitable for enabling transportation of the portable storage device over a surface. One or more extendable handles are coupled to the storage device. The one or more extendable handles slideably extend from inside hollow portions of one or more first elongated frame members attached to the storage body.

A dolly for attachment to a vehicle hitch is disclosed. The dolly includes a connection assembly for connecting and disconnecting the dolly to the vehicle hitch. The connection assembly also allows to position the dolly from a ramp position in which the support surface is inclined, to a loading position in which the support surface is raised and parallel to the ground, for loading the object from the dolly to the vehicle. The connection assembly also allows to position the dolly from the loading position to a transport position. In the transport position, the support surface is upright and extends along the rear of the vehicle, for transporting the dolly with the vehicle, once the object has been loaded in the vehicle. A method of operating the dolly is also provided.

A wheel dolly for raising a vehicle wheel off the floor is disclosed. The dolly has at least two wheel straddle bars, each straddle bar having a non-swing caster assembly. A swing caster assembly is connected to each straddle bar. The assembly includes a stationary frame supporting a swing axle, a swing frame that rotates about the swing axle, and a swing caster connected to swing frame. The swing caster defines a swivel plane. A lift bar connects the two wheel straddle bars. The dolly can transition between two configurations: a lowered configuration, wherein the swivel plane is not parallel to the floor, and a raised configuration, wherein the swivel plane is substantially parallel to the floor.

The assembled-type traveling carriage includes: the telescopic cylindrical body being an extendable telescopic cylindrical body rotatably provided with a first screw at each end thereof, and incorporating an actuator configured to extend and withdraw a nest; a joint block provided with a second screw; a traveler rotatably provided with the first screw and attached a driving device thereto; and a coupling rod rotatably provided with the first screw on each end thereof. A first planar frame body is assembled by screwing joint blocks to four of the telescopic cylindrical bodies, screwing the travelers to the joint blocks such that the travelers are positioned on extension lines of the telescopic cylindrical bodies, and coupling one ends of the four telescopic cylindrical bodies to one another by the coupling rods through the joint blocks.

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.

A cart includes a flat base, at least three wheels coupled to the flat base onto one flat side of it and a flexible casing coupled to the flat base along a circumference of the flat base. The flexible casing is extendable in a direction that is substantially perpendicular to the flat base between a first casing position and a second casing position.

A manually manipulated apparatus supports a piece of equipment beneath a rail car gate of a railroad hopper car during maintenance or removal of the gate. The apparatus has a frame and a support frame attached to the frame. The support frame is selectively raisable and lowerable between a lowered position adjacent to the frame to a raised position extending upwardly above the frame. The support frame has an equipment engagement member which has an upwardly facing surface which is adapted to engage a downwardly facing surface of the equipment when the support frame is in the raised position.

The present disclosure relates to a double stroller, with a frame thereof including three side supports and two transverse supports. Each two adjacent side supports are connected to each other via one transverse support. Each transverse support includes at least one connecting rod assembly, and each connecting rod assembly includes an outer connecting rod fixedly connected with the side support on a left or right side and an inner connecting rod fixedly connected with the side support in the middle. The outer connecting rod is connected to the inner connecting rod in a horizontally rotatable manner. The outer connecting rods and inner connecting rods connected in a horizontally rotatable manner to enable the side supports on two sides to close together as the outer connecting, rods are turned transversely and folded, and thus, after being folded, the space occupied by the double stroller in the left-right direction is lessened.
