Door fastener device

A fastener device for a door or a gate and adapted to engage an upright, including a lock comprising:

• a frame with a carrier plate and an edge plate, the frame being arranged to be mounted with said edge plate against the upright;
• at least one bolt slidably mounted on the frame between a retracted and a projecting position and extending in its projecting position with a distal extremity over a predetermined distance out of the edge plate and extending beyond said upright;
• and
• an actuation mechanism arranged to move said bolt from its retracted to its projecting position and vice versa and comprising an operating member acting on an abutment element on the bolt, which abutment element is separated by a predetermined length of the bolt from said distal extremity thereof,
• wherein said bolt comprises a first part having said distal extremity and a second part provided with said abutment element and means operable from a projecting portion of the bolt to move the first and second parts axially with respect to one another and to fix them in different axial positions to one another, which means comprise a screw thread on said first bolt part and a corresponding screw thread on said second bolt part having a screw axis directed according to a longitudinal axis of the bolt, the first and the second bolt parts being screwable onto one another over different overlapping distances to adjust said predetermined length of the bolt and thereby said predetermined distance over which the bolt projects out of the edge plate, one of said screw threads being an inner screw thread and another of said screw threads an outer screw thread provided on a projecting portion of the part onto which the outer screw thread is provided, an axial hole being provided through the distal extremity of the bolt and at least into said projecting portion, the hole being provided at least in said projecting portion with an internal screw thread and the lock comprises a set screw arranged to be screwed in said hole to lock said projecting portion in said inner screw thread by laterally expanding said projecting portion therein.

A fastener device for a door or a gate and adapted to engage an upright, including a lock comprising:

• a frame with a carrier plate and an edge plate, the frame being arranged to be mounted with said edge plate against said upright;
• at least one bolt having a predetermined length and comprising a main bolt part, formed by a first bolt part having a length corresponding to said predetermined length of the bolt, and a second bolt part having an abutment element and cooperating with the main bolt part, which main bolt part is guided at least in a first and a second guide on the frame to be movable between a retracted and a projecting position and has a distal extremity which extends in said projecting position over a predetermined distance out of the end plate to project beyond said upright;
• an actuation mechanism arranged to move said main bolt part from its retracted to its projecting position and vice versa and comprising an operating member acting on said abutment element;
• and
• means operable from outside the fastener device for bringing the main bolt part in different axial positions with respect to the second bolt part and for fixing the main bolt part in these positions to the second bolt part to adjust said predetermined distance over which said distal extremity extends in the projecting position out of the edge plate, the length of the main bolt part being such that in said different axial positions, in the projecting position of the bolt, the main bolt part remains guided by said first and second guides,
• wherein said second bolt part comprises a slide element which is provided with said abutment element, which projects through at least one slot out of the first bolt part and which is slidably mounted in said first bolt part between a first position wherein it engages one end of said slot and a second position wherein it engages an opposite end of said slot, said means for bringing the main bolt part in different axial positions with respect to the second bolt part and for fixing it in these positions to the second bolt part comprising a threaded shank extending axially within the first bolt part and engaging the slide element and the first bolt part, which threaded shank is accessible through an axial hole provided in said distal extremity to rotate it either clockwise or anti-clockwise to slide said slide element axially in the first bolt part.
