Abstract (en)
[origin: ES8302835A1] A tumbler lock having an outer cylinder and an inner cylinder rotatably mounted therein with springless plate-shaped tumblers which move freely in guide slots. Tumbler locks of known construction can be opened by unauthorized persons because an object can be inserted through the windows in the plate-shaped tumblers required for the insertion of the key, wedged against the side faces of the windows and the tumblers lifted from their locked state. This is foreclosed in the invention because the side flanks of the windows in the area of the key guide which are parallel to the direction of the motion of the tumblers are covered by protective strips connected with the inner cylinder.
