  • Patent number: 11767046
    Abstract: A novel logistics system is disclosed involving a roll container (100) with a base (110) and two elongated supports (120) that are supported by the base (110). The supports each have a plurality of individual slots (122) provided in a spaced apart configuration along the supports (120) for receiving a tab (133, 134) of a respective plurality of shelves (130) in a spaced apart configuration. The roll container may further include a folding mechanism between the base and the supports for turning the supports between an operational state and a folded state. In the operational state of the roll container the supports extend transversally in respect to the base. In the folded state of the roll container the supports extend parallel to the base.

  • Patent number: 11498599
    Abstract: According to an example aspect of the present disclosure, there is provided a novel chassis (100) for a roll container (1000). The chassis (100) features a first arm (121), a second arm (122), and a crossmember (110) for connecting the first arm (121) to the second arm (122) so as to form the chassis (100). The crossmember (110) is formed to be less resistant to mechanical strain than that of the first and second arm (121, 122). The crossmember (110) is such that it can be repeatedly attached to and detached from the first and second arm (121, 122).

  • Patent number: 10118450
    Abstract: The present invention provides a tow bar assembly, which may be retrofitted to a dolly while maintaining convenient space saving properties of permanently fitted tow bars. The novel tow bar assembly includes a tow bar, a shaft and a biasing member, such as a spring, biasing the tow bar towards an upright orientation about an axis of revolution. The shaft has a first end and a second end, which opposes the first end. The shaft connects the tow bar to the dolly from the ends so as to provide rotation of the tow bar in respect to the dolly about the axis of revolution. The shaft features an inner cavity, which extends along the axis of revolution. The biasing member is arranged into the cavity of the shaft and rotationally secured thereto. The shaft also features a first end plug at the first end of the shaft for enclosing the biasing member to the cavity. The first end plug rotationally locks the biasing member to the dolly.

  • Patent number: 9162814
    Abstract: The adaptor pallet includes two sets of parallel tracks, a lifting structure connecting the tracks at an elevated level, a loading end for introducing dollies to the adapter pallet, and a closed end including a stopper for limiting the movement of dollies. The adaptor pallet further includes a locking plate which is rotatably connected to the lifting structure at one end, while another end of the locking plate includes a stopper protrusion and a member for releasably affixing the locking plate into a horizontal position such that the stopper protrusion limits the movement of the dollies at the loading end of the adaptor pallet, wherein the locking plate is releasable from the horizontal position into an angled position for opening the loading end of the adaptor pallet.
