SAFETY DEVICES IN GENERAL; {SAFETY DEVICES FOR PRESSES}
Definition statement
This subclass/group covers:

Safety systems allowing protection of the operator from a machine, a machine tool, a press. Safety systems designed specifically for certain machine/tool/application should be classified in the group related to this specific machine/tool/application if a group related to this safety system exists.

Special rules of classification within this subclass

F16P is only related to general use and general configuration of safety systems. More detailed systems, or specific features of these systems should be classified in the corresponding subclasses. For example a general description of a light grid used to avoid a person to enter a dangerous area has to be classified in F16P, however if the invention is related to a specific feature of the light grid (e.g. detailing the elctronical circuits or the light grid) and not linked directly to the safety, F16P should not be given but rather G01V.

Safety devices independent of the control and operation of any machine (protective devices for the eyes or ears, worn on the body or carried in the hand, A61F 9/00, A61F 11/00)
Definition statement
This subclass/group covers:

Safety systems which are independent from the machine, and which are meant to protect the operator by creating a physical barrier between the operator and a dangerous area. No interaction exist between the safety system and the machine.

Fixed screens or hoods
Definition statement
This subclass/group covers:

Illustrative example of subject matter classified in this group: The document DE102007062813 discloses a screen (4) which provides a barrier in order to avoid an operator to enter a dangerous area. In use the barrier does not move, except that the panels (2) can be adjusted in height. Once these panels are adjusted, the screen generally does not move with respect to the machine.

Definition statement
This subclass/group covers:

Safety systems which depend on the machine by way of any possible interactions and which are meant to protect the operator from being injured by the machine.

{Safety devices for guarding the human operator of punch presses or like machine tools performing an opening and closing travel}
Definition statement
This subclass/group covers:

Illustrative example of subject matter classified in this group: The document EP1990130 discloses a screen which depends on the functioning of the machine, in the sense that there is an interaction between the screen and the machine. Here the safety device performs an opening and closing travel in order to restrict access to the machine.

in connection with the locking of doors, covers, guards, or like members giving access to moving machine parts
Definition statement
This subclass/group covers:

The activation or desactivation of the machine is linked to the state of the lock which is provided on the doors, covers guards or like members which give access to moving machine parts or by extension to the machine in general.

Illustrative example of subject matter classified in this group: EP2289672 if the door 3.1 is closed the machine 1 can be active. If the door 3.1 is opened the machine can not be active.
