For example, although the locking mechanism was described as including both a hidden locking feature (hook) and an exposed locking feature (plunger), it should be noted that in some cases the plunger may be hidden. As should be appreciated, plungers may be unsightly and potentially dangerous. A protruding plunger may result in the plunger being accidentally sheared off when it comes into contact with some other object. Also, if the plunger is accidentally slammed on a finger, or if the plunger hooks on clothing, it can cause injury or damage, leaving a negative impression on the user.
