A coupling for swivably coupling an arm to a post, the coupling in use cooperating with the post as an engaged element via a post interface, and with the arm as an engaged element via an arm interface, wherein the coupling including its interfaces provides limited relative rotational movement between the arm and the post about a swivel axis extending along a longitudinal axis of the post, wherein the limited rotational movement is provided in a rotational zone that corresponds to a single revolution about the longitudinal axis. The disclosure further relates to a coupling system, and to a monitor support.

Provided are a levitating display device and an operating method thereof. The display device includes a frame unit and a panel unit, wherein the frame unit includes a power receiver and a wireless power transmitter configured to wirelessly transmit power received by the power receiver to the panel unit, and the panel unit includes a wireless power receiver configured to wirelessly receive the power from the wireless power transmitter and a display configured to receive the power from the wireless power receiver and display an image.

An adaptable door mounting support for acquiring a door gap and for supporting a door slab. The door mounting support comprises a frame member including first and second A-shaped segments interconnected by a rectangular bottom section and together defining a door support channel therebetween, and a tie device configured to meter the door gap and hold the door slab off the ground. A width of the door support channel is equal or larger than a thickness of the door slab. The tie device includes a cable tie extending between the A-shaped segments and across the door support channel, and a locking member attached to the cable tie by sliding over the cable tie. The locking member is slidable over the cable tie in one direction only and is lockable on the cable tie to adjust a distance between the cable tie and the bottom section of the frame member.

A mounting device for joining a display protector onto a display of an apparatus includes a frame having an alignment cut-out which provides at least one alignment portion serving to align the display protector and, to this end, being contactable with the display protector, and at least one cut-out providing an accommodating portion. Further, the frame includes a supporting member engageable with the accommodating portion with an engaging portion, so that the supporting member projects toward the one side. In addition, the supporting member includes at least one display alignment portion which is aligned with respect to the alignment portion when the at least one supporting member is engaged with the frame, and which serves to align a display or the apparatus.

An electronic device case including a case body to encase a handheld electronic device, the case body including at least one planar surface, and one or more wings to fold into the planar surface in a first position and to extend past an edge of the at least one planar surface in a second position. The one or more wings provide handles by which a user of the handheld electronic device can support a weight of the handheld electronic device.

A support stand for supporting a volumetric modular unit above the ground is disclosed. The support stand includes a top portion with a top surface for contacting and supporting an underside of the modular unit above the ground. A bottom portion with a bottom surface supports the top portion at an elevation above the ground against the underside of the modular unit. An elevating portion has a top side connected to the top portion, a bottom side connected to the bottom portion, and an elevating span between the top side and the bottom side. A pad is connected to the bottom portion. The pad has a bottom surface for contacting and supporting the bottom portion against the ground, an inner pad perimeter and an outer pad perimeter. The top surface is parallel with the bottom surface. The underside and weight of the modular unit is supported on the top surface.

A gantry-type positioning device includes a planar base parallel to first and second directions. Two first linear axes are arranged in the first direction, each having a first linear drive. A frame held by the first linear axes is movable in the first direction, and comprises two transverse and two longitudinal beams. The transverse beams carry second linear axes with second linear drives parallel to the second direction, so that a movable element arranged between the transverse beams is movably held by the second linear actuators. The frame is flexibly constructed such that the movable element is rotatable about a third direction which is perpendicular to the first and second directions. With respect to the third direction, the movable element is guidable by a guide surface of only one of the transverse beams serving as a guide beam for the movable element.
