Abstract
A pocket slide opening door assembly including a door leaf having a top edge, a door frame assembly, and a sliding assembly for slideable translation of the door leaf in relation to the door frame assembly between a closed position and an open position, wherein the assembly is provided in a plurality of parts for assembly in situ, including in a first part the door leaf, in a second part the door frame assembly with bay or pocket configured to receive the door leaf, or in second and third parts the door frame assembly and separate bay or pocket configured to receive the door leaf, and wherein the door assembly is disposed and configured in manner which prevents ligature about the door leaf top edge and in manner which prevents access to the sliding assembly for tamper purpose or for ligature purpose.
Claims20
An anti-ligature pocket slide opening door assembly for use in a building which houses an individual at a risk of intentional self-harming, comprising:
- a door frame assembly which comprises a headpiece, two sidepieces, and a pocket;
- a door leaf which comprises a top edge, a closing side edge, a pocket side edge and a bottom edge;
- and
- a sliding assembly for slideable translation of the door leaf in relation to the door frame assembly between a closed position and an open position, wherein the door frame assembly provides, with the door leaf in the closed position:
- an overhead overlap (0°) with the door leaf at the top edge provided by at least one overhead overlap element to the door frame assembly, provided separate from the headpiece for securing by an anti-tamper and anti-ligature fixings, wherein the overhead overlap is characterised by an overhead overlap height o.h being a height of the door leaf overlapped by the at least one overhead overlap element;
- a closing side overlap (Oc) with the door leaf at the closing side edge;
- and
- a pocket side overlap (Op) with the door leaf at the pocket side edge, wherein Op is in a range from 1.2 cm to 5 cm;
- wherein the sliding assembly is an electromagnetic drive sliding assembly having components disposed in relation to the electromagnetic drive sliding assembly,
- and configured to decelerate the door leaf approaching the closed position or the open position or to absorb impact of the door leaf on the door frame assembly, at a moment of reaching the closed position or the open position;
- and
- wherein:
- the door leaf is oversized, and the door frame assembly including the pocket is correspondingly oversized, and the oversized door leaf has a height D.h. in a range from 220 cm up to 300 cm,
- the overhead overlap element is oversized,
- and the oversized overhead overlap element has an oversized overhead overlap height o.h in a range from 5 cm to 40 cm,
- and the sliding assembly is disposed within the headpiece of the oversized door frame assembly at a top portion of, or overhead, the oversized overhead overlap element,
- which prevents access to the sliding assembly for a ligature purpose, with the oversized door leaf in the closed position;
- and wherein:
- the oversized door frame assembly, with the oversized door leaf in the open position or in a partially open position, provides an oversized overhead overlap void which has an overlap void height ov.h in a range from 7 cm to 54 cm being a sum of o.h and a vertical separation between the top edge of the oversized door leaf and the sliding assembly, which prevents access to the sliding assembly for a ligature purpose, with the oversized door leaf in the open position or in the partially open position.

A kit for an anti ligature pocket slide opening door assembly for use in a building which houses an individual at a risk of intentional self-harming, wherein the kit comprises:
- a door frame assembly which comprises a headpiece, a bottom piece and two sidepieces and a pocket,
- a door leaf which comprises a door leaf top edge, a closing side edge, a pocket side edge and a bottom edge,
- a sliding assembly for slideable translation of the door leaf in relation to the door frame assembly between a closed position and an open position, and
- at least one overhead overlap element securable by anti ligature fixings
- wherein the door frame assembly provides, with the door leaf in the closed position:
- an overhead overlap (OO) with the door leaf at the top edge overhead overlap element to the door frame assembly, provided separate from the headpiece for securing by an anti tamper and anti ligature fixings, wherein the overhead overlap is characterised by an overhead overlap height o.h being a height of the door leaf overlapped by the at least one overhead overlap element;
- a closing side overlap (OC) with the door leaf at the closing side edge;
- and
- a pocket side overlap (OP) with the door leaf at the pocket side edge, wherein OP is in a range from 1.2 cm to 5 cm;
- wherein the sliding assembly is an electromagnetic drive sliding assembly having components disposed in relation to the electromagnetic drive sliding assembly, and configured to decelerate the door leaf approaching the closed position or the open position or to absorb impact of the door leaf on the door frame assembly, at a moment of reaching the closed position or the open position;
- and wherein:
- the pocket and the door leaf are oversized, and the door frame assembly is correspondingly oversized, and the oversized door leaf has a height D.h. in a range from 220 cm up to 300 cm;
- the overhead overlap element is oversized, and has an oversized overhead overlap height o.h in a range from 5 cm to 40 cm;
- and the sliding assembly is disposed within the headpiece of the oversized door frame assembly at a top portion of, or overhead, the oversized overhead overlap element, which prevents access to the sliding assembly for a ligature purpose, with the oversized door leaf in the closed position;
- and the oversized door frame assembly, with the oversized door leaf in the open position or in a partially open position, provides an oversized overhead overlap void which has an overlap void height ov.h in a range from 7 cm to 54 cm being a sum of o.h and a vertical separation between the top edge of the oversized door leaf and the sliding assembly, whereby with the oversized door leaf in the open position or in the partially open position, the oversized overlap void prevents access to the sliding assembly for a ligature purpose.
