Abstract
A handle assembly includes a lock cylinder of a selected one of a first standard or a different second standard. A tail piece extends from the lock cylinder. The handle assembly also includes a vertical tubular member, a horizontal tubular member and a transition plate. The transition plate is disposed within the vertical tubular member and is moveable between a first position and a different second position. The transition plate accommodates installation of the lock cylinder of the first standard when in the first position and installation of the lock cylinder of the second standard when in the second position. A mechanical linkage is coupled to the tail piece and effects movement of a locking bolt in response to turning of a key in the lock cylinder.
Claims20
A transition plate for engagement with lock cylinders of at least a first standard and a different second standard, for installation in a door pull that has a vertical tubular member that defines an alignment hole, the transition plate comprising a transition plate member having a front surface and an opposite back surface, the transition plate member defining:
- (a) a first plurality of holes passing therethrough corresponding to the first standard and including:
- a first tail piece hole, at least one first set screw hole for coupling the transition plate member to a lock cylinder of the first standard and a first position holding screw hole for holding the transition plate member in a first fixed relationship with the vertical tubular member when a set screw is passed through the alignment hole and secured to the transition plate member by engagement with the first position holding screw hole;
- and
- (b) a second plurality of holes passing therethrough corresponding to the first second standard and spaced apart from the first plurality of holes and including:
- a second tail piece hole, at least one second set screw hole for coupling the transition plate member to a lock cylinder of the second standard and a second position holding screw hole for holding the transition plate member in a second fixed relationship different from the first fixed relationship, with the vertical tubular member when the set screw is passed through the alignment hole and secured to the transition plate member by engagement with the second position holding screw hole.
A handle assembly, comprising:
- (a) a lock cylinder of a selected one of a first standard or a different second standard, a tail piece extending therefrom;
- (b) a vertical tubular member;
- (c) a horizontal tubular member;
- (d) a transition plate disposed within the vertical tubular member, the transition plate moveable between a first position and a different second position that is vertically spaced apart from the first position, in which the transition plate accommodates installation of the lock cylinder of the first standard when in the first position and installation of the lock cylinder of the second standard when in the second position;
- and
- (e) a mechanical linkage coupled to the tail piece that effects movement of a locking bolt in response to turning of a key in the lock cylinder.
A door employing a door locking system for use with a selected one of a lock cylinder of a first standard and a lock cylinder of a second standard, different from the first standard, the lock cylinder of a first standard and the lock cylinder of a second standard each including a tail piece extending laterally therefrom, the door comprising:
- (a) a planar door member;
- (b) a lock cylinder of a selected one of a first standard or a different second standard, a tail piece extending therefrom;
- (c) a vertical tubular member;
- (d) a horizontal tubular member that couples the first vertical tubular member to the planar door member;
- (e) a transition plate disposed within the vertical tubular member, the transition plate vertically moveable between a first position and a different second position that is vertically spaced apart from the first position, in which the transition plate accommodates installation of the lock cylinder of the first standard when in the first position and installation of the lock cylinder of the second standard when in the second position;
- (f) a bolt having a locked position and an unlocked position for locking the door;
- and
- (g) a mechanical linkage coupling the tail piece to the bolt,
- wherein when the lock cylinder is manipulated to unlock the door, the mechanical linkage causes the bolt to move into the unlocked position and wherein when the lock cylinder is manipulated to lock the door, the mechanical linkage causes the bolt to move into the locked position.
A method of installing a lock cylinder having a tail piece and defining at least one locking cylinder set screw hole, in a door mechanism that includes a vertical tubular member coupled to a horizontal tubular member, comprising the steps of:
- (a) determining whether the lock cylinder is of a first standard or of a second standard;
- (b) if the lock cylinder is of the first standard, then aligning a first position holding screw hole in a transition plate member with a vertical tube set screw hole defined by the vertical tubular member and securing the transition plate member vertical tube by screwing a set screw through the vertical tube set screw hole into the first position holding screw hole defined by the transition plate;
- (c) if the lock cylinder is of the second standard, then aligning a second position holding screw hole in the transition plate member with the vertical tube set screw hole defined by the vertical tubular member and securing transition plate member to the vertical tube by screwing the set screw through the vertical tube set screw hole into the second positioning holding screw hole defined by the transition plate;
- (d) placing the lock cylinder through an opening defined by the vertical tubular member that is in alignment with the horizontal tubular member so that the tail piece extends through a tail piece hole defined by the transition plate member into the horizontal tubular member;
- and
- (e) securing the locking cylinder to the transition plate by passing a locking cylinder set screw through a locking cylinder set screw hole defined by the transition plate and screwing locking cylinder set screw into a locking cylinder set screw hole defined by the locking cylinder.
A universal back plate for engagement with both a lock cylinder of a first standard and a lock cylinder of a second standard that is different from the first standard, each lock cylinder including a tail piece extending therefrom and defining at least one set screw hole that is complementary in shape to a set screw wherein the set screw hole corresponding to a lock cylinder of the first standard is spaced apart at a first distance from the tail piece and wherein the set screw hole corresponding to a lock cylinder of the second standard is spaced apart at a second distance from the tail piece, the first distance being different from the second distance, the back plate comprising:
- a plate member defining a tail piece opening and at least a first set screw opening having a shape that accommodates both a set screw engaged in the set screw hole of the lock cylinder of the first standard at the first distance from the tail piece opening when the plate member is affixed to the lock cylinder of the first standard and a set screw engaged in the set screw hole of the lock cylinder of the second standard at the second distance from the tail piece opening when the plate member is affixed to the lock cylinder of the second standard.
