Abstract

The invention concerns the design of a plastic clip (1) for holding together sheet-like objects. In order to be able to insert objects into the clip easily by hand along as long a pinch line as possible and so that they are held with as great a force as possible, the invention calls for the two halves (2, 3) of the clip to be hinged to each other by two hinge points (8), disposed a certain distance apart from each other and both parallel to the pinch line (6), each hinge point being surrounded by a U-shaped spring (7) whose arms (9) are braced against the grips (4, 5) of the two halves (2, 3) of the clip.

Description

DESCRIPTION

Plastic clip for clamping sheet-shaped

objects

The invention relates to a clip made of plastic for clamping the sheet-like objects, wherein the clamping jaws of two clamping levers hinged to each other by means of spring force along a clamping line are braced against one another.

In a conventional clothespin, the two clamping levers are penetrated by the cylindrical coil of a torsion spring and guided in rotation. The two spring ends engage with angled ridges on the outer surfaces of the jaws. Such a system is unsuitable if articles are to be clamped along a clamping line longer, as for example, when sealing open bags, containers and the like of the case.

For the latter purpose brackets according to the DE-GM 89 12 654 more suitable because they have clamping levers with elongated jaws. This clamping levers are braced against each other by an integrally molded leaf spring, which brings the problem with it to generate a sufficiently large clamping force.

Finally, from DE-A 36 23 766 known to connect consisting of plastic clamping lever with the front ends of a bracket, which is U-shaped and is made of spring steel. With such a clamp can indeed generate a large clamping force, but the nip line is relatively short. If one would want to extend the nip line in this known clamp.

SUBSTITUTE SHEET which automatically would have to be accompanied by an extension of the clamp, the resistance of the spring to spread the bracket by hand would be too large.

The invention is therefore based on the object of developing a brace for the longest possible nip line, which is manually easy to operate and also produces a sufficient clamping force to securely close for example, open pouches.

Starting from the bracket shape of the DE-GM 89 12 654, the solution according to the invention the task set is that the clip comprises two parallel to the nip line spaced from one another bearings for the clamping levers which are each embraced by a U-shaped spring, the legs against the clamping jaws are resiliently tensioned. According to this arrangement, a relatively short U-shaped springs opens up the possibility. to form brackets of desired nip length, which generates a sufficient clamping force and yet a relatively easy operation is made possible with manual force.

Although it is known from DE-PS 377 467, to guide two metal jaws at two mutually spaced balls and be tightened with a long spring sleeve against the balls. Thus, the object of the invention, but is not solved because the long spring sleeve requires a disproportionately large spreading, when a sufficient clamping force to be generated along the nip line.

The clip according to the invention can be used for various purposes, such as for clamping

SUBSTITUTE SHEET a plurality of sheets, for clamping heavy objects or for closing the open packages, bags o. The like. The invention is not limited to these application examples.

As part of the claims, numerous embodiments of the subject matter of the invention are disclosed.

So for example it is convenient to form the single bearing point of a pan-like groove at the one clamping lever and of a suitable engaging in the groove bead at the other clamping lever, by which they are held encompassing spring leg in its Eingriffsεtellung. It has proven to be expedient when the single spring is fixed with its legs on the clamping jaws of the clip snap fit.

In an advantageous embodiment of the invention, the single clamping jaw in the region of each bearing one of the staple length corresponding, opposite to the clamping line open recess, into which engage the legs of the spring. One can therefore push the spring from above into the recess and thereby bring about a frictional connection of the clamping levers in their bearings.

Advantageously, the recess has the inside delimiting wall below the bearing axis a strip-shaped projection which is engaged from behind by a bead-like thickening of the leg edges of the spring. the snap closure like compound of the clamping lever is facilitated by this arrangement and their solubility allows.

SUBSTITUTE SHEET The arrangement of each clamping lever located on handle portion zweckmäßigerweiεe occurs between the bearing points, of course, the grip part has a wegstrebende from the nip line design.

However, the invention is not limited thereto, that two clamping levers have to be individually prepared and bonded with each other. There is also the possibility of connecting the clamping lever in the region of the bearing points each by a thin curved wall portion to form a one-piece bracket to each other by injection molding, wherein it is only recommended to form suitable centering measures between the two legs of the one-piece clamping lever, so that when pushing the springs a unique clamping position is achieved.

These and other features are schematic and are for example shown in the drawing. Show it

Fig. 1 is a side view of a clip,

Fig. 2 is an end view of the clamp according to Fig. 1,

Fig. 3 shows a cross section through the clamp along the line III-III in FIG. 1 (in an enlarged view),

Fig. 4 is a partial cross section through the

Clamp lever of the bracket in the areas of their bearing in the open position and

Fig. 5 shows a cross section through an alternative one-piece clamp.

ERSATZBLÄΓT The side view of Fig. 1 shows a clip in, for example, natural size, as may be particularly the like for closing the open bags, bag o. Is used.. but the invention is not limited to the illustrated size of the clip.

With (6) a nip line is designated, the length of which represents the gauge length of the clip (1). The clip (1) itself consists of two clamping levers (2,3) made of plastic, which are connected together articulatedly in the region of two bearing points (8), as can be seen for example from Figures 3 and 4. FIG. This connection of the clamping lever (2,3) is however only to be understood as Drehzentrierung. The staple (1) requires the additional arrangement of U-springs (7) in order to connect the clamping levers (2,3) non-positively with each other.

As is apparent particularly from the cross section shown in FIG. 3, the clamping jaw (4) of the clamping lever (2) in the region of the bearing points (8) has a socket-like groove (10), into which a bead (11) of the clamping jaw (5) the other clamping lever (3) engages. Now, when a U-shaped spring (7), which may consist of a resilient plastic, from above, with its legs (9) about the bearing point (8), ie over the groove (10) and the bead (11) is pushed away affects the elasticity of the limbs (9) against the walls (13) of the clamping jaws (4,5) and clamp these in the region of the nip line (6) firmly against each other.

To the U-spring (7) from above to be inserted into the bearing points (8) are provided upwardly open recesses (12) on the clamping jaws (4,5) can be limited, the inside of the walls (13). As especially FIG. 1, can now be the U-springs (7) easily from above into the recesses (12) are running.

SUBSTITUTE SHEET The outer sides of the walls (13) have strip-like projections (15) extending from bead-like thickened portions (16) of the legs (9) of the U-spring (7) can be gripped from behind. The shape of the U-spring (7) is thus set so that the bead-like thickening (16) during the pressing of the spring (7) in the recess (12) can pass (15) or the strip-shaped projections. In the snap-closure position shown in FIG. 3, the legs (9) then need to be more biased the spring (7) so far that they exert a sufficient clamping pressure on the clamping jaws (4,5).

It has now in hand, to be produced by appropriate dimensioning of the springs (7) the respective desired closing pressure of the clip (1). It is essential that the bearing axis (14) of each bearing point (8) from above through the web of the spring (7) is encompassed.

It is easy to see that the spring (7), can be easily released from their clamping position by means of suitable tools which engage beneath the spring legs (9).

In the example of Fig. 5 is an alternative of the invention is shown, it being understood by a one-piece clip 1 '. the two clamping levers (2,3) are connected to each other instead of that shown in Fig. 3 bearing point (8) by an arched and weakened wall portion (18) which acts as a hinge. Here, too, it takes only the U-shaped spring (7) from above aufzuclipsen to form an effective clamp.
