Description

  The present invention relates to a fall prevention device, and more specifically to a fall prevention device for a wall-hanging type device that is locked to a back plate fixed to a wall.

  Conventionally, in consideration of space saving, various devices having a relatively thin shape have been proposed as a so-called wall-mounted type that can be attached to a wall in a home, office, factory, or the like. There are various methods for hanging such a wall-mounted device on a wall. For example, a wall-mounted indoor unit of an air conditioner does not require a mounting bracket to be attached to the wall side to be prepared for each indoor unit. In consideration, as shown in FIG. 3 of Patent Document 1, the indoor unit 10 is fixed to the wall surface 20 by being locked to a hook portion on the upper portion of the mounting bracket 21 attached to the wall surface 20. When such a wall-hanging method for a wall-mounted device is used, the structure is such that the insertion portion on the back surface of the wall-mounted device is inserted into and locked with the hook portion of the mounting bracket fixed to the wall. 9 and 9, the hooking portion 9 of the back plate 2 has a large allowance so that it is not easily detached even if vibration is applied.
