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

Technical field

The invention relates to a quick-closing system, which is used in particular for hinged bags, in particular briefcases, school bags and the like, in which two interlocking closure parts are connected by means of a detachable hook connection.

The closure of this type should be designed so that the parts of the system can be made primarily in one piece, without detachable parts, and the handling and operation that lead to the connection and separation of the system parts is substantially simplified compared to existing systems. The opening of the hinged lid and the necessary opening of the system should be perceived by the average user as a single movement by simple operation. Closure of the closure is also substantially facilitated by the two conical guides of one of the closure members.

BACKGROUND OF THE INVENTION

The object of the above mentioned closing system of the conventional construction is characterized in that the opening of the system and opening of the hinged lid or closing of the system and closing of the hinged lid follow separately and are perceived by the user as two independent movements. The opening of the system and the opening of the hinged lid cannot, due to the construction, occur in one movement sequence and, moreover, force the user to palpate or use his other hand at a certain point in the opening procedure.

In this case, the prior art patent FR-PS 2, 193.309 (Delka S.A.), FIG. 1 and 2, which clearly implies a different, more complicated or described procedure. Disconnection of the two closure parts occurs in two clearly separated movement sequences, in a straight line by pressing one part and in the other by sliding it out of the other part, also using the other hand or at least one finger thereof. With one hand pressing the closing part which is attached to the hinged lid, this part is released from the anchorage, with the other hand the same part is pulled upwards, which in turn leads to the opening of the bag

The movement patterns described above explain why, for example, e.g. pupils whose school bags are fitted with such or similar slide-in closures have difficulties opening them. Often, these closures, usually placed on the bag two at a time and pressed together, inadvertently back into the closed position, which, especially for younger children (preschool age) or older, motorically disadvantaged people, often constitutes an almost insurmountable obstacle to the smooth use of such locking systems. bags. For the purpose described above, conventional plug-in closures are mostly made of metal, resulting in a more complex mechanical design, with multiple detachable components, higher weight and higher manufacturing cost of the systems.

SUMMARY OF THE INVENTION

The task of the new closure system is to achieve the above objective by avoiding the shortcomings of existing systems,

The invention consists in that, in particular on the hinged lid, the part with the movable hole, which fits into the second part mounted on the bag body, has one guide on each side as well as a part protruding from the base plate.

According to the invention, the guides with a rear cross-section which protrude from the base plate and are positioned at an acute angle with respect to each other, together with rails with a rear cross-section which correspond to the cross-section of the guides, engage the guides and are opposed to each other at the same angle as the guides of the first closure member so that the connection of the two closure members is not necessary.

J

By means of a further embodiment of the closure parts according to the invention, in the closed position, the hook of one part, which is located between the rails and protrudes from the base plate, is inserted into the hole of the other part located on the movable plate. associated with the closure member in a short opening process by means of lateral angularly spaced edges having a rear cross-section (grooving), releasing the closure member which is attached to the hinged lid with a hole. The user can hold the locking lever in the grip during the entire opening process. The opening is caused by indentation, which is only a transient movement. The opening of the system and the opening of the hinged lid are connected to a continuous movement. Closing is carried out with guides that are placed at an acute angle to each other and automatically positions and guides one part to the other so that these movements can also be easily performed by children or motorly disadvantaged persons.

DETAILED DESCRIPTION OF THE INVENTION

In the Figures 1 and 2 is shown a closure for use for hinged lids, briefcases, school bags and the like, with a marked part attached to the lid of the bag and a 2 part mounted on the bag body.

The closure member 1 comprises two strips 4 facing each other at an acute angle, whose rear cross-section profiles correspond to the same profiles of the guides 3 that protrude from the base plate of the part 2. These guides are positioned opposite each other at the same acute angle as the strips 4 of the first closure part, wherein the strips 4 are engaged with the guides 3, the hook connection having one hook 5 which protrudes from the base plate of the part 2 and is located between the guides 3 of this part 2 and one counterpart 8 a hole 6, which is resiliently disposed on the closure member 1 comprising the strips 4 and is retractable with the hook 5.
