| (54) | Handle for door or window frames |
| (57) A handle for door or window frames comprises at least a rotatable operating shaft
(2) with a square cross-section, exiting a surface (3) of the door or window frame
(1); the handle (4) comprises: a body (5) for connection to the surface (3) of the
door or window frame (1) and having a through-opening (6) engaged by the shaft (2);
a handgrip (7) which can be coupled in a matching fashion to the operating shaft (2),
so that when the handgrip (7) is rotated about an axis (X) coinciding with the square
shaft (2) the configuration of the door or window frame (1) is changed from closed
to open; elastic means (8) positioned in the body (5) and designed to allow handgrip
(7) positioning in a predetermined position corresponding to the door or window frame
(1) closed configuration; means (9) for stably joining the handgrip (7) to the square
shaft (2); means (10) for releasable axial retention of the handgrip (7) on the square
shaft (2), located at the elastic means (8) and acting on the end portion (7a) of
the handgrip (7), where the handgrip (7) is coupled to the square shaft (2), so as
to stably hold the handgrip (7) on the shaft (2) irrespective of the presence of the
stable joining means (9).
