A method (101) of removing a Flat Display (3), preferably provided with a Flat Display Mounting Interface (FDMI), from a support (5) such as a stand or wall mount, using a system (1) according to any of the preceding claims, the method comprising the step of: - rotating (103), by a user, the hook device about the rotation axis into the second position wherein the locking arrangement allows removal of the first frame from the second frame.
The method according to claim 13, wherein the method further comprises the steps of: - moving (105), by the user, the one of the first frame and the second frame relative to the other of the first frame and the second frame for disengaging the hook device from the other of the first frame and the second frame; and - disconnecting (107), by the user, the first frame from the second frame.

Description

According to a first aspect, the present disclosure relates to a system arranged for removably attaching a Flat Display, preferably provided with a Flat Display Mounting Interface (FDMI), to a support such as a stand or wall mount. According to a second aspect, the present disclosure relates to methods of removing and removably attaching a Flat Display (FD), preferably provided with a Flat Display Mounting Interface (FDMI), from a support such as a stand or wall mount, using a system according to the first aspect of the present disclosure. The FDMI, also known as VESA Mounting Interface Standard (MIS) or VESA mount, is a family of standards defined by the Video Electronics Standards Association (VESA) for mounting flat panel monitors, televisions, and other displays to stands or wall mounts. It is implemented on most modern flat-panel monitors and televisions. A known system comprises a frame, to which the Flat Display is attached, that can be secured to another frame, like a VESA bracket, by means of one or more screws. The screw(s) ensure(s) that the Flat Display, attached to the first frame, cannot be tilted forward, and becomes detached from the VESA bracket. A technician can remove the Flat Display by unscrewing the screw(s). To prevent the Flat Display from falling and/or breaking of screw(s) or other components of the system, the technician must support the Flat Display during the unscrewing of the screw(s). Especially for large (and heavy) Flat Displays this may be a difficult and challenging task. In another known system, the Flat Display is attached to a VESA bracket by means of a spring system comprising two or more springs. The spring system holds a bracket/pawl in place by applying pressure on said bracket/pawl. This prevents the Flat Display from coming loose from the VESA bracket. The Flat Display may be detached and removed from the bracket by pulling the two or more springs down at the same time. A drawback of such a system is that the detaching and removing has to be done by at least two technicians. The technician has to pull the two or more springs, being posited at least on both sides of the Flat Display, at the same time and also simultaneously tilt the Flat Display to be able to lift the Flat Display off the VESA bracket. Especially with large (and heavy) Flat Displays this is very difficult. Attaching the Flat Display to the VESA bracket also has the above-mentioned disadvantages. It is therefore an object of the present disclosure to provide a system and methods that at least partly overcome one or more of the above-mentioned drawbacks. The system according to the first aspect of the present disclosure comprises: a first frame arranged for being connected to the Flat Display, preferably via the FDMI thereof; anda second frame arranged for being connected to the support;a locking arrangement, comprised by one of the first frame or the second frame, and arranged for locking the one of the first frame and the second frame to the other of the first frame and the second frame;a hook device, comprised by the locking arrangement, arranged for being rotated about a rotation axis into a first position wherein the locking arrangement locks, by the hook device, to the other of the first frame and the second frame and for being rotated into a second position wherein the locking arrangement allows removal of the first frame from the second frame, wherein the hook device is provided with a primary hook element arranged for locking the first frame to the second frame and a secondary hook element arranged for being in contact with the other of the first frame and the second frame for maintaining the hook device in the second position. With the system according to the present disclosure, the first frame, to which the Flat Display is connected, can be held in the same position on the second frame and switch between an attached state and a detached state by means of the hook device comprised by the locking arrangement. By switching from the attached state to the detached state, a single technician is able to safely remove the Flat Display from the second frame, connected to the support, with a minimized risk of the Flat Display falling down and/or damaging components of the system during the process of removing of the Flat Display. The same advantage applies in the process of removably attaching the Flat Display. The design of the system according to the present disclosure is from a technical aspect much easier and comprises less components as compared to existing systems. Further, the system may be made of a more robust material; no plastic components, only metal components. This allows to also mount heavy (up to 150 kg) Flat Displays. In an embodiment, the locking arrangement further comprises: a biasing device arranged for providing a force to the hook device for biasing the hook device into the first position. The force, provided by the biasing device, may increase when moving the hook device from
