Abstract

The fastening consists of two pieces (1,2) held in a closed position by a detachable hook-connection. One of the pieces (2) has two rails (3) sloping towards each other at an acute angle and protruding from a base plate. The rails have a back-tapered cross-section. The other piece (1) has two bars (4) engaging with the rails and sloping at the same acute angle towards each other as the rails. The hook connection has a hook (5) between the two rails and protruding from the base plate, A counter element (8) engaging with the hook is especially in the form of an eyelet (6).

Description

The invention relates to a quick release system for use on preferably bags with hinged lids, especially briefcases, school bags and the like, in which the connection of two interlocking closure parts by a Detachable hook connection is made.

A closure of this type should be designed that the respective system units preferably consist of one piece each, without partial components can, and the handling and handling for Connection and disconnection of the system parts, in Comparison with existing systems, essential is simplified. The opening of the hinged lid and the system opening required for this should also be due to the ease of use of the closure only more than one by the average user Movement can be perceived. Closing the The closure is made by two conical guide rails of a closure part as well much easier.

Locking systems used for the purpose mentioned at the beginning are usually of a conventional design characterized that the system opening and that Open the hinged lid or the system lock and the closing of the hinged lid take place separately and by the user as two in relation and dependency related movements true be taken. The system opening and flap opening due to their design, they cannot be combined in one Sequence of movements take place and also force the User, at a certain point in the opening distance reach around or additionally his second Hand.

In detail at this point it is next State of the art patent FR-PS 2, 193.309 (Delka S.A.), Figs. 1 and 2, cited, which clearly shows the different, more complicated or how it works as described above. The two closure parts are separated into two clearly separated movements, namely firstly by pressing and secondly by Sliding one part out of the other, too is the use of the second hand or at least one finger of this close. With one hand by pressing the one attached to the flap Closure part of this released from the anchorage, with the other the same part is pulled upwards, resulting in the opening of the bag leads.

Movements described above make it clear why e.g. especially school children, their school bags with such or similar snap closures equipped, have problems opening them. They often snap, usually in pairs on the Bag arranged and operated at the same time, also inadvertently in the closed position back, which is especially useful for smaller children (in Preschool age) or older, motor-disadvantaged People often face an almost insurmountable hurdle in the fluent use of such locking systems or Represents bags. Also conventional snap locks mostly for the purpose described above Metal, which is a more complex structure of the Mechanics, with several parts, one higher weight and higher production costs of the Systems.

The task of the new locking system is that task outlined above while avoiding the To achieve disadvantages of existing systems.

The invention is that a preferably attached to the flap cover, with a Movable eyelet part, in one, on Pocket body mounted, one on each side Rail and one protruding from the base plate having the second part engages.

The inventive design of the two protruding from the base plate at an acute angle mutually inclined guide rails with undercut Cross-sectional profile, as well as the under same acute angle as the rails of the first Closure part, inclined towards each other, with the Rails that can be brought into engagement with for undercut cross-sectional profile of the rails Corresponding cross-sectional profile, the Bring the two locking parts together imperative measure to connect the two Closure parts avoided.

Through the further execution of the invention Locking parts will be in the closed position the between the rails from the base plate arranged upstanding hook of one part with the eyelet of the other part engaged. When loosening this connection by lifting the eyelet supporting movable bridge and in connection standing closure part is due to the in acute angle inclined towards each other, an undercut Cross-sectional profile (grooves) Side edges, the eyelet, on Hinged lid fastened fastener after a short time Opening path released. The user can do this Locking lever during the entire opening process keep enclosed - it arises when opening the impression that it is only one continuous movement. System opening and flap opening become a continuous movement united. When closing it comes through the acute angles to inclined rails, too an automatic alignment and guidance of the a part on the other, so that children or motor-disadvantaged people this movement can run easily.
