The present invention relates to a device for convenient opening of mechanical, airtight locking lever locks for vessels of all kinds, mainly but for beer mugs or the like.

The construction and mode of operation of this device result from the following Description with the aid of the accompanying drawing.

The lid α is attached in a hinge-like manner to the handle b of the jug or the like and has a rubber sealing washer c and a slot d extending through it in the direction of the handle b. A metal rail consisting of two parts e and e ¹ , pushed over one another and held together by the screw i , is inserted through this slot d , on which the cover α is fastened on the one hand and the locking lever f and the hook bracket g on the other. Both parts e and e ^{1 of} the metal rail have downward respectively. upwardly curved side walls, which BEZW in association with the ground. the cover of the slot d form a channel passing through the cover α , in which the slide h and ρ move. The rear end of the part e is bent to form a thumb lever e ^'2 upward and the side walls are extended in two downwardly directed lobes e ³ that the fastening eye b ¹ b of the handle catch between them. A pivot pin b ² provided with washers and cotter pin is inserted through the tab e ³ and the fastening eye b ^{1 of} the handle b , around which the lid α can be rotated and opened after the lid closure has been released. Between the two flaps e ^s comes out the slide h provided with a push button 0 at the rear, which when the lock is released is pushed so far forward that it cannot hit the fastening eye b ^{1 of} the handle b when the lid α is opened .

The lock itself is one of the well-known lever locks. With the aid of the locking lever f, two eccentrically attached disks / to which the hook bracket g is attached can be rotated around a fixed point k of the metal rail e ^i. The hook bracket g reaches around. the nose m attached to the jug itself and is attached to the panes / in such a way that, as soon as it is lifted above its highest position, it tightens the locking lever f firmly onto the lid α and in this way creates a completely airtight seal .

So that one does not need both hands when opening this closure, namely one to hold the jug and the other to open the closure, the following device has been made, which allows the closure with the hand that holds the jug by the handle b, easy and convenient to open. .

As already mentioned above, in the rear part e the two-part metal rail moves, which for this purpose is supported by a support r (by means of bent flaps

the side walls formed transverse web) is provided, a slide h. To limit its stroke, this slide h has a slot w through which the screw i passes, and a button o or the like at the rear to press it. A second slide p moves in the front part e ^{1 of} the metal rail, but only by influencing the previously mentioned slide h. This second slide ρ has two upwardly curved lugs p ¹ and p ² and is also limited in its hub by a web q formed by bent lugs on the vertical walls of the front part e ^{l of} the metal rail. The mode of operation of this device described above is as follows: With the jug closed, as shown in Figs. 1 and 2 of the drawing, the thumb of the hand holding the jug by the handle b is pressed against the surface 0 of the slide h so that it moves forward. moves and first pushes against the nose p ^{1 of} the second slider ρ and then pushes the latter so far forward that the second nose p ' ^{2 of the} same pushes against the hook bracket g . With further pressure in the direction of the arrow, the tension of the hook bracket g is overcome, the locking lever / snaps back and the locking is released, as shown in Fig. 3 and in Fig. 1 dotted. The two slides h and p, as well as the two parts e and e ^{] of} the metal rail can also easily be combined into one piece, whereby the manufacture of the device described is still considerably simplified. Pateντ claim: A device for opening lever locks for vessels of any kind, characterized in that with the help of one or several slides seated one behind the other are pressed against the locking device in this way that the locking lever strikes back and as a result the lock is released, for the purpose of opening it with the hand that holds the vessel.
