In a retracted configuration, the arms are folded inward toward the central hub so that the arms do not extend beyond the outer dimension of the top face. In an extended configuration, the arms extend outward from the central hub beyond the outer dimension of the top face. | 2017-02-09 |

20170037888 | PLUG CONNECTION ELEMENT AND TRANSPORTATION BOX HAVING PLUG CONNECTION ELEMENTS - The invention relates to a plug connection element for releasable connecting two adjacent wall elements of a transportation box, having a first U-shaped receptacle for an edge region of the first wall element, which is formed from a first base plate and an inner leg angled to the latter and an adjoined angled outer leg, and a second U-shaped receptacle for an edge region of the second wall element, which is formed from a second base plate and an inner leg angled to the latter and an adjoined angled outer leg, wherein the first and second U-shaped receptacle are identically aligned, wherein the first and second receptacle are connected to each other by means of a bending joint, so that the U-shaped receptacles is adjustable in terms of their angular position to each other. | 2017-02-09 |
20170037889 | CLAMP DEVICE WITH RESILIENCE - A clamp device with resilience can be coupled to a slender bar. The slender bar includes a connection rod and a bar shaft which are connected to each other. The clamp device with resilience includes a clamping portion and a fixing portion. The clamping portion includes two clamping plates for containing the connection rod. The fixing portion is connected to the clamping portion and adapted to fix the bar shaft in place. Rotation of the connection rod causes the two clamping plates to abut against polygonal vertices of the connection rod and therefore move away from each other. Therefore, the connection rod rotates by a fixed angle on each instance. | 2017-02-09 |
