Abstract

A paper punch includes a base part which has a positioning surface on the bottom side thereof for positioning the same on a table top. At least two punching tools are displaceably supported with respect to the base part to punch holes into documents. A hand-held applies pressure on the punching tools and is supported about a pivot axis in a limited pivoting manner by way of a front region of the base part. The base part has a grip cutout which is open toward the rear side of the base part and which is delimited toward the top by a ceiling wall extending at a distance from the positioning surface and toward the front by a transverse wall.

Claims (24)

1. A paper punch comprising:

(a) a base part, said base part comprising an underside, a positioning surface for being set onto a table top on the underside, a front region having a contact surface for a document, a rear side, a ceiling wall running at a distance from the positioning surface, a transverse wall, side walls extending toward the rear side, and a grip cutout;

(b) at least two punch tools for punching a document and mounted to be vertically displaceable with regard to the base part; and

(c) a hand lever for applying force to the at least two punch tools, said hand lever being mounted so as to pivot about a pivot axle over the front region of the base part, said hand lever having a free end extending at a distance from the base part in a direction to the rear side of the base part;

wherein the grip cutout is open towards the rear side, is delimited upwards by the ceiling wall, frontwards by the transverse wall, and laterally by the side walls, has a height of at least 10 mm, and has a width of at least 70 mm;

wherein the base part has a lower punch part made of sheet metal, the lower punch part having the ceiling wall, and a scrap trough made of plastic, the scrap trough having the positioning surface;

wherein the scrap trough and the lower punch part are releasable connected with one another;

wherein the ceiling wall has a cutout with an open edge; and

wherein a part of the scrap trough engages into the cutout of the ceiling wall.

2. The paper punch according to claim 1 , wherein the grip cutout has a height of at least 15 mm.

3. The paper punch according to claim 1 , wherein the grip cutout has a width of at least 80 mm.

4. The paper punch according to claim 1 , wherein the grip cutout extends over the entire width of the base part.

5. The paper punch according to claim 1 , wherein the transverse wall is an integral part of the scrap trough.

6. The paper punch according to claim 1 , wherein a center part of the transverse wall is domed forward.

7. A paper punch comprising:

(a) a base part, said base part comprising an underside, a positioning surface for being set onto a table top on the underside, a front region having a contact surface for a document, a rear side, a ceiling wall running at a distance from the positioning surface, a transverse wall, side walls extending toward the rear side, and a grip cutout;

(b) at least two punch tools for punching a document and mounted to be vertically displaceable with regard to the base part; and

(c) a hand lever for applying force to the at least two punch tools, said hand lever being mounted so as to pivot about a pivot axle over the front region of the base part, said hand lever having a free end extending at a distance from the base part in a direction to the rear side of the base part;

wherein said grip cutout is open towards the rear side, is delimited upwards by the ceiling wall, frontwards by the transverse wall, and laterally by the side walls, has a height of at least 10 mm, and has a width of at least 70 mm;

wherein the base part has a lower punch part made of sheet metal, the lower punch part having the ceiling wall, and a scrap trough made of plastic, the scrap trough having the positioning surface;

wherein the scrap trough and the lower punch part are releasably connected with one another;

wherein the scrap trough has a continuation lying against the ceiling wall; and

wherein the grip cutout is lined by the continuation of the scrap trough.

8. The paper punch according to claim 7 , wherein the continuation of the scrap trough also lies against the side walls of the base part.
