Abstract: A tire door clearance system is disclosed that includes a non-flammable material that is fastened at a first portion thereof on an inner side thereof to any of a door and door frame, and an intumescent material applied to the inner side of the non-flammable material at a second portion thereof.

Abstract: Handle device for operating doors, windows and the like. The handle device comprises a first element (3, 103), which is rotatable about an axis of rotation, a second element (8, 108), and a coupling device (10, 110) which is arranged to selectively allow and prevent relative rotation about the axis of rotation between the first and the second element. The coupling device comprises a first coupling member (11, 111) which is connected to or forming an integral part of the first element. A second coupling member (12) is connected to or forming an integral part of the second element (112). At least one engaging member (13, 13, 113, 114) is movable between an engagement position in which it simultaneously engages the first and the second coupling members to thereby prevent relative rotation between the first and second element and a release position in which it is disengaged from at least one of the first and second coupling members to thereby allow relative rotation between the first and second element.

Abstract: A fire door clearance system is disclosed that includes a non-flammable material that is fastened at a first portion thereof on an inner side thereof to any of a door and door frame, and an intumescent material applied to the inner side of the non-flammable material at a second portion thereof.

Abstract: A cylinder lock and key system. The plugs comprise a housing having a cylindrical bore; and a cylindrical plug which is rotatable and which exhibits a front end and a keyway. The keys comprise a key bow; and a key blade is rotatable about the rotational axis when inserted. The plugs and keys are provided with cooperating stop surfaces for defining the fully inserted position of the keys. At least one first stop surface is in contact with a corresponding second stop surface when a key is inserted in the keyway of a lock. At least two first stop surfaces of each key are arranged adjacent each other and at least two second stop surfaces of each lock are arranged adjacent each other, at or in proximity to the keyway. A cylinder lock and key combination, a key, a key blank and a cylinder lock are also disclosed.

Abstract: A door assembly includes a first door skin and a second door skin spaced apart from the first door skin. The assembly also includes an energy sensor generating an energy signature signal and a memory storing a door component operating signature. A controller is coupled to the accelerometer and forms a comparison of the energy signature signal to the door component operating signature and generates a door component operation status signal in response to the comparison.
