Abstract: A display hook for supporting items of merchandise includes a rod assembly and a pair of mechanically interlocked time delay arms medially disposed on the rod assembly. The time delay arms are sequentially movable to permit a potential purchaser to manipulate an item beyond the time delay arms for removal from the display hook. The time delay arms include a guide tube slidingly disposed on the rod assembly, a first arm rotatably mounted on the guide tube and a second arm spaced outwardly from the first arm and fixedly mounted on the guide tube. The first arm is spaced-apart from the second arm sufficiently to permit at least one of the items to be disposed between the arms. The first arm has a circumferentially extending groove and the guide tube has a key that cooperates with the groove to permit limited rotation between the guide tube and the first arm.

Abstract: A security device for an item of merchandise having at least one removable component includes a sensor attached to the item of merchandise. The sensor has an extension that extends outwardly from the sensor in a first direction generally parallel to an axis defined by the item of merchandise sufficiently to prevent a removable component from being removed from the item of merchandise. The extension is preferably a plate having an outer surface that is adhered to the sensor and an inner surface that is adhered to the item of merchandise. The extension includes a leg depending from the plate in a second direction that defines an angle with the axis defined by the item of merchandise sufficiently to prevent a removable component from being removed from the item of merchandise when the plate is adhered to the item of merchandise. The sensor is electrically connected to an alarm circuit.
