Description

[0001] The invention relates to a template for marking at least one drill hole position on a door having two main surfaces and an end surface having a mortise for a mortise lock and a recess for the forend of the mortise lock, wherein the template comprises a marking member to be positioned adjacent, in particular abutting and / or parallel to a main surface of the door. The marking member comprises at least one marking means for marking the at least one drill hole position on a main surface. The template further comprises a support having an end for abutment formed to be positioned in the recess, and e.g to abut the bottom of the recess and / or the end surface of the door, and, e.g. once fastened in the recess, to enable holding the marking member adjacent a main face. The present invention also relates to a method for marking at least one drill hole position on a door using such a template.

[0002] A mortise lock is a lock which is mounted in an elongated cut-out, a mortise, in an end surface of a door. A mortise lock comprises a forend for fastening the mortise lock to the door. The forend is usually embedded in a relatively shallow elongated recess surrounding the mortise when the mortise lock is mounted in the door. Typically, the contours of the forend substantially match the contours of the recess. The forend may be fastened to the bottom of the recess using fastening means, e.g. screws. The mortise lock further comprises a lock case comprising at least one connection point and / or opening for door hardware, e.g. a spindle, a cylinder and / or a thumb turn, and possibly at least one hole for accommodating at least one fastening means, e.g. through bolts, for fastening escutcheons and / or roses to the door. The door comprises at least one hole for accommodating the door hardware when a mortise lock is mounted in the mortise and operatively coupled to the door hardware. A mortise lock typically comprises a latch bolt or roller configured to extend through the forend and engage a strike plate positioned on a door frame when the door is closed. The mortise lock may comprise a dead bolt configured to extend through the forend when the mortise lock is in locked state. In that case, the strike plate typically comprises an opening to receive the dead bolt when the mortise lock is in locked state.

[0003] Mortise locks have various lock case depths. The longitudinal centerline of the mortise may coincide with the longitudinal centerline (extending in the height direction of the door) of the end surface of the door or may be positioned eccentrically with respect to the longitudinal centerline of the end surface of the door. The end surface of the door may be stepped in a direction transverse to the longitudinal (or height) direction, the step forming a lip along a longitudinal edge of the end surface. Doors comprising such a lip are known as lipped doors.

[0004] Newly manufactured doors in which a mortise lock is yet to be mounted are often delivered to a customer already provided with a mortise for mounting the mortise lock. Openings in a main surface of the door for accommodating door hardware are however often not provided by the manufacturer as there is a large variety of mortise locks and door hardware a customer might opt for.

[0005] As a consequence, customers are frequently tasked with marking at least one drill hole position on at least one main surface of the door corresponding to the chosen mortise lock and / or door hardware. Templates exist for marking at least one drill hole position on at least one main surface of the door for various types of mortise locks and / or door hardware.

[0006] NL 2030047 relates to a template for marking positions of drill holes on a door, the door in its end face being provided with a mortise for a mortise lock and a recess for the forend of the mortise lock. The template is provided with a L-shaped profile part and a fitting plate. The L-shaped profile part is provided with a short leg, intended for abutment to the end surface of the door and a long leg, intended for abutment to a main surface of the door. The long leg is provided with at least one marking opening for marking a position of a drill hole. The fitting plate is connected to the short leg through an adjustable connection and is configured to be accommodated in the recess for the forend. The adjustable connection allows movement of the fitting plate exclusively in a direction perpendicular to the long leg.
