A lock fittings for removably attaching a first wall to a second wall, said first and second walls being orthogonal to each other, said lock fittings comprising:
- a lock assembly (4) having a mounting face (30) and a fitting face (26), mounting (30) fitting (26) and said faces being orthogonal to each other;
- a locking mechanism having a spring-loaded lock (8) and a cover (5) for housing said lock mechanism, said lock (8) being held in the unlocked position by a step edge (14) on said lock (8) against a shoulder (31) on said cover (5) by a biasing spring (10);
- said locking mechanism being mounted on said fitting face (26) and forming a recess (46) with said fitting (26), and said recess (46) being face adjacent to said lock (8);
- a lever having a pivot (38) at one end, a rounded end (45) and a screw driver slot (39) proximate at the other, said rounded end (45), said lever being in contact (B) with said lock (8) and being operable to urge said lock (8) against said spring (10) for engaging said step against edge (14) with said shoulder (31) by turning said lever (9);
- and
- a locking projection (48) attached to said second wall, part of said second wall for inserting into said recess (46), said locking projection (48) cooperating with said lock (8) for engaging with said projection (48), when said part of said second wall is fully inserted into said recess (46) and said lock (8) is released from said shoulder (31) and urged into the locked position by said spring (10);
- wherein said locking projection (48) and said second wall is removeably attached to the said first wall by operating on said lever (9) with a screw driver engaging said screw driver slot (39) thereby urging said lock (8) against said spring (10) and engaging said step (14) with said shoulder (31).
The lock fittings according to claims 4 or 5, wherein the surfaces of said pair of guides (18a,18b) are inclined towards said mounting face (30) at an angle (D) from the vertical axis.
The lock fittings according to any one of the preceding claims, wherein the line of action of said spring 10) is offset from point of contact (B) towards said mounting face (30).
The lock fittings according to any one of the preceding claims, wherein the line of action of said spring (10) is offset from said step (14) and shoulder (31) contact point towards said mounting face (30)
The lock fittings according of the to any one of the preceding claims, wherein the line of action of said spring falls within the distance between the perpendicular line at said contact (B) and said
