Abstract
The invention concerns a locking device for a screwed part (1) which is mounted on a threaded rod (7) and is used to connect a second object (8) to a first object. The locking device consists of a key and a cap (3) whose base is located between the screwed part (1) and one of the objects (8) and whose cylinder wall surrounds the screwed part (1) and terminates in the region of the end face of the latter. The surfaces, in particular the generated surfaces, of the screwed parts (1) of a plurality of first objects differ from one another, and the part of the key grasping the screwed parts (1) is adapted in a form-locking manner thereto. The cap (3) is at such a short distance from the point of the screwed part (1) which projects furthest outwards radially that the key can surround the screwed part (1). The invention is characterized in that, located between the screwed part (1) and the abutment surface of one of the objects (8) which faces the latter, are stop means (4, 5, 2, 9) which prevent the screwed part (1) from rotating and working loose, and can be brought into their unlocking position only by the key when it is placed on the screwed part (1). In this way, objects are rendered particularly secure against theft.
Claims
1. Verriegelungsvorrichtung für ein Schraubteil (1), das auf (an) einer Gewindestange (7) sitzt und zum Verbinden eines zweiten Gegenstandes (8) mit einem ersten Gegenstand dient, bestehend aus einem Schlüssel und einer Kappe (3), deren Boden sich zwischen Schraubteil (1) und einem der Gegenstände (8) befindet, deren Zylinderwand das Schraubteil (1) umgibt und im Bereich der Stirnfläche des Schraubteils (1) endet, wobei sich die Oberflächen, insbesondere Mantelfächen der Schraubteile (1) mehrerer erster Gegenstände voneinander unterscheiden, der die Schraubteile (1) erfassende Teil des Schlüssels dem Schraubteil (1) formschlüssig angepaßt ist und die Kappe (3) einen solchen geringen Abstand von der am weitesten radial nach außen ragenden Stelle des Schraubteils (1) hat, daß der Schlüssel das Schraubteil (1) umgreifen kann, dadurch gekennzeichnet, daß sich zwischen Schraubteil (1) und der ihm zugewandten Anlagefläche eines der Gegenstände (8) Arretierungsmittel (4,5,2,9) befinden, die das Schraubteil (1) gegen lösende Verdrehung arretieren und nur durch den Schlüssel durch dessen Aufsetzen auf das Schraubteil (1) in ihre Entar- retierung gebracht werden können.A locking device for a screw member (1) seated on (at) a threaded rod (7) and for connecting a second object (8) to a first object, consisting of a key and a cap (3) whose bottom is between the screw part (1) and one of the objects (8), the cylinder wall surrounds the screw member (1) and ends in the region of the end face of the screw (1), wherein the surfaces, in particular shell areas of the screw (1) a plurality of first objects from each other distinguish, which is the screw (1) detecting part of the key to the screw (1) adapted and the cap (3) such a small distance from the radially outwardly projecting point of the screw (1) that the key Screw part (1) can engage around, characterized in that between the screw (1) and the contact surface facing him one of the objects (8) locking means (4,5,2,9) located, which lock the screw (1) against loosening twisting and can be brought into their Entar- retainer only by the key by placing it on the screw (1).
2. Verriegelungsvorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß die Arretierungsmittel eine Federstahlscheibe (2) aufweisen, die im angespannten Zustand drehfest mit dem einen Gegenstand (8) verbunden ist und mehrere Rastnasen (9) besitzt, die, von außen unbelastet, in Einbuchtungen (10) des Schraubteils (1) einrasten können und durch Druck von außen das Schraubteil (1) freigeben.2. Locking device according to claim 1, characterized in that the locking means comprise a spring steel disc (2) which is non-rotatably connected in the stressed state with the one object (8) and has a plurality of latching lugs (9) which, unloaded from the outside, in indentations (10) of the screw (1) can engage and release by external pressure the screw (1).
