(57) The present invention relates to a mortise lock for windows, doors and the like,
of the type formed in an aluminium profile, characterised in that it consists of:
- an elongated central element (1) which has a likewise elongated hollow with a curved
surface in the shape of a shell defined at each end, the shell-shaped surface being
situated at the bottom end of the element designed so that the user can use his finger
to press said element downwards in order to open the lock, and the shell-shaped surface
being situated at the top end of the element designed so that the user can use his
finger to press said element upwards, in order for said element to move a latch (21)
which will act as a bolt and therefore close the lock, said latch (21) being attached
to the element (1) by means of a screw pin (20), with the insertion of a small member
(19) with a knurl, the purpose of which is to prevent the latch (21) from sliding
due to the impact caused when the window, door or the like is closed; and
- an elastic element (16) fixed inside the aluminium body (2), which acts as a support
for attaching the return spring (26), limits the movement of the element (1), presses
the button (15) and halts the movement of the element (1) when it is pressed by the
spring (26) when the lock is in the open position.
