Patent number: 11767046Abstract: 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.Type: GrantFiled: June 18, 2021Date of Patent: September 26, 2023Assignee: K.

Patent number: 10118450Abstract: 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.Type: GrantFiled: November 10, 2015Date of Patent: November 6, 2018Assignee: K. Hartwell Oy AbInventor: Jack Grönholm
