<p>The holder for flat cylinder lock keys comprises a cuboidal housing with a small slot at each end. A knob projecting through a longitudinal slot in the large face of the housing pushes the key ward out through the slot in the housing end. The key holder is not subject to accidental emergence of keys. The housing (10) is formed in two halves detachably plugged together. The keys (19, 20) each have a knob (29) detachably fixed with a screw (26) through the hole in the key head (22). Two leaf springs force a widened section (33) of the knob shaft into the circular widening (15a) of the longitudinal slots (13a). When the knob (29) is pressed, it may be slid along the slot (13) pushing the key ward out of the aperture (16a) in the housing end.</p> |
