Definitions
- the invention relates to a clip stapler for ungeloch ⁇ th documents of the type specified in the preamble of claims 1 to 3.
- a stapler of this type is known (US Pat. No. 3,099,269), which has a back cover made of flat material, such as cardboard or plastic, and a cross section which is essentially U-shaped and which can be displaced transversely to an edge edge of the back cover.
- the clip consists of two clip legs connected in one piece to one another on a straight apex line, which can be elastically spread apart about a bending axis parallel to the tilt line, between which the documents can be clamped together with the back cover.
- the rear bracket leg engages behind the back cover, while the front bracket leg in the region of its free edge opposite the apex line has an elongated clamping rib which projects beyond the inside of the clip and is obliquely delimited by the sliding edge which is inclined towards the free edge.
- the clamping rib is aligned there parallel to the apex line and therefore strikes against the edge of the stack of documents with the entire length of its push-on flank when pushed onto a stack of documents.
- the invention has for its object to provide a stapler of the type specified, which is particularly easy to manufacture and handle.
- the invention is primarily based on the idea of designing the clip so that it can be pushed directly onto the document to be filed without risk of damage.
- the clamping rib runs at least on the side of its push-on flank over part of its longitudinal extent obliquely to the apex line of the clip. This ensures that the Knd ⁇ - rib when pushing the clip onto the document with its push-on flank initially only punctually and not over its entire length strikes the edge of the document and the clamp leg is thereby slightly elastically spread apart.
- the clamping rib which has already been partially expanded, slides with its inclined push-on flank onto the edge of the document without any risk of damage.
- the clamping rib is at least on the side of its push-on flank in the direction of its longitudinal extension in an undulating or zigzag shape.
- the slide-on flank advantageously has the greatest distance from the apex line in the central region of its longitudinal extension and thus has an arrow-shaped shape pointing in the slide-on direction.
- the push-on flank it is also possible for the push-on flank to have the greatest distance from the apex line at two points of its longitudinal extent, preferably spaced apart from one another in the center. This ensures that the clip aligns itself automatically on the edge of the document when it is pushed onto the document.
- the free edge of the front bracket leg also has a preferably arrow-shaped outline which is essentially adapted to the course of the push-on flank.
- the clamping rib on its side opposite the push-on flank can be limited by a stop flank acting against a limit stop of the back cover.
- the longitudinal direction of the stop flank is expediently aligned parallel to the apex line.
- the stop flank projects substantially vertically above the front leg of the clip and, according to a preferred embodiment of the invention, directly adjoins the push-on flank of the clamping rib at an angle of 70 ° to 90 ° .
- a further preferred embodiment of the invention provides that the slide-on flank has an inclined course which is S-shaped in cross section and which, over its entire height, opens towards the free edge of the front bracket leg, the slanted course being variable over the longitudinal extent of the slide-on flank .
- the limit stop can be designed as a stop bar projecting beyond the level of the back cover ; difi molded on the Rfickendeckel and / or glued. It is also possible to limit the Form as a metal or plastic fitting or as a staple projecting preferably with their bent free legs over the level of the back cover.
- the front cover has a cutout that extends to the edge for the passage of the front clip leg , wherein the cutout can have a contour that is adapted to the front staple, possibly at an oblique angle.
- the rear clip leg can be provided with at least one latching cam or a latching rib and the back cover with a latching recess for receiving the latching cam or the latching rib.
- the locking recess which can also be designed as an opening in the back cover, is expediently aligned parallel to the adjacent edge edge of the back cover, while several locking cams are provided on the rear bracket leg in a row parallel to the corner line or a locking rib aligned parallel to the corner line can be.
- Figure 1 shows a section through a clip stapler.
- FIG. 2 shows a plan view of the clip of the clamping stapler according to FIG. 1 in an enlarged representation
- FIG. 3 shows a section along the section line 3-3 of FIG. 2;
- FIG. 4 shows a section along the section line 4-4 of FIG. 2;
- FIG. 5 shows a plan view of an exemplary embodiment of a clip modified compared to FIG. 2.
- the clip stapler shown in FIG. 1 has a back cover 10 made of cardboard or plastic film, a front cover 12 integrally hinged to an edge edge 14 on the back cover 10, and a front cover 12 pushed onto the back cover 10 from the rear over the edge edge 14 , limitedly displaceable clamp 16 transversely to the edge 14.
- the clip 16 which is made of a resilient plastic material and is essentially U-shaped in cross section, has two clip legs 20, 22 which are integrally connected to one another on a straight apex line 18, of which the rear clip leg 20 engages behind the back cover 10 and the front clip leg 22 with elastic spreading in relation to the rear clamp leg 20 with a clamping rib 24 onto which flat material 26 lying on the front of the back cover 10 can be pushed.
- On the front cover 12 there is an ir * : contour adapted to the front clip leg 22 up to the edge 14 Raised closed cutout 28 is punched out, which allows the front cover 12 to pivot about the edge 14 and to move the clip 16 on the back cover 10.
- the clamping rib 24 pointing towards the inside of the clip is bounded towards the free edge 32 of the clip leg 22 by an oblique push-on flank 34 which is S-shaped in cross section and on the opposite side by a stop surface 36 projecting vertically above the clip leg 22.
- the stop flank 36 adjoins the push-on flank 34 of the clamping rib 24 at an angle of 70 ° to 90 °.
- the stop flank 36 In the retracted state of the clamp 16, the stop flank 36 abuts against a stop surface 30 which projects rigidly beyond the back cover 10 and thus ensures that the clamp 16 cannot be pulled off the back cover 10 when the clamp connection is released.
- the limit stop 30 can consist of cardboard or plastic strips which are integrally connected to the back cover 10 and are glued to it flatly, or of fittings made of metal, plastic or staples.
- the stop flank 36 is aligned in its longitudinal extent parallel to the apex line 18 of the clamp 14.
- the clamping rib has a wavy or longitudinal extension on the side of its push-on flank zigzag-shaped course, and is thus aligned at least over part of its longitudinal extent obliquely to the apex line 18.
- This course is indicated in FIGS. 2 and 5 by a line 42 running on the push-on flank 34 at a defined height above the rib tip 40.
- the push-on flank 34 has a centrally arranged wave crest 44, while in the embodiment according to FIG. 5 two wave crests 44 'are provided which are arranged laterally from the center.
- the free edge 32 of the front bracket leg 22 has an arrow-shaped contour.
- an orientation or grip marking 46 is provided on the outside of the clamp leg 22 in the region of the crest 44.
- the push-on flank 34 has an inclined course which is variable in cross-section S-shaped over its longitudinal extent.
