Abstract

The paper punch consists essentially of a lower part (1) equipped with side cheeks (2) and of a pressure plate (3) articulated on the side cheeks (2). Pressure is transmitted between the pressure plate (3) and hole punches (4) by means of a pressure bar (5) which is parallel to the pivot axis (32) of the pressure plate (3), bears with its upper edge against the pressure plate (3) and on its lower edge (53) has two downwardly pointing pressure studs (52) engaging into cup-like recesses (71) of the hole-punch heads (7) and being supported pivotably with their tip against the bottoms of these. <IMAGE>

2. Description of the Related Art In this type of document punching device, a pressing mechanism curved in a convex shape is arranged on the lower surface of a pressing plate formed as a single-arm lever. This pressing mechanism is in contact with the flat or convexly curved end surface of the punching die. Therefore, the contact between the pressing mechanism and the punching die is point-like or linear, resulting in a relatively high surface pressure. Therefore, when the pushing plate is pushed down, a large frictional force is generated between the pressing plate and the punching die, and this frictional force gives a tilting moment to the punching die. This tilting measurement causes sliding friction on the axial guide of the punching die, which hinders the operation of the document puncher.

Structure and Effect The technical idea of the present invention is that the push plate does not directly act on the punching die, but indirectly acts on the pusher plate and the punching die through a rotatable pressing mechanism. And to prevent lateral frictional forces during operation of the document punch. According to this technical idea, the present invention provides
In order to achieve the above object, the pressing mechanism is a push rail that is arranged parallel to the pivot axis of the push plate, and the upper ridge is in contact with the push plate, and the push rail is pivotable like a pendulum at the contact portion. Formed on the lower edge of the push rail, there are arranged two downward push pins that are inserted into the bowl-shaped recesses of the punch head and that have their tips pivotally supported at the bottom. To do. If the area of the punch die head is guided by the lower axial guide, the bending moment does not act on the punch when the document punch is operated, thus preventing the sliding friction in the axial direction when the document punch is operated. can do. Advantageously, the punch head, which abuts the punch, forms a thickened portion, the ridge of which has an annular shoulder which serves as a support for the coil spring.

According to another advantageous embodiment of the invention, at least one ridge, which serves as a stop on the upper edge of the push rail, is provided on the underside of the push plate, at least on the longitudinal side of the push rail. Instead of providing the ridge on one side, it is also possible to provide a groove into which the upper edge of the push rail can be inserted.

According to another advantageous embodiment of the invention, the push rail is loosely pivoted in the region of its upper edge to the side plate of the push plate. For this purpose, the push rail is provided in the region of its upper ridge with a pin which projects towards the end face and which is inserted loosely into a hole provided in the side plate of the push plate. In this case, the lower edge of the pin abuts the lower edge of the hole. With this construction, the push rail is pulled back to its base position together with the push plate in any case, for example one of the punching dies is stuck in a stack of thick hard sheets despite the action of the return spring. Even if the push rail does not fall out.

The document punch shown in the drawings is generally a side plate 2
And a push plate 3 pivotally attached to a side plate 2 of the lower portion 1. The lower region of the punching die 4 is guided by the holes 22 and the upper region is guided by the region between the plates 21 which has the wide head 7. The plate 21 is formed by bending the side plate 2. Further, a push rail 5 is provided in parallel with the turning shaft 32 of the push plate 3. The upper edge of the push rail 5 has a groove 33 formed by a bent portion 31 that is bent inward.
Two push pins 52 directed downward are arranged on the lower ridge 53 of the push rail 5 that abuts on the push plate 3 in the area of. The push pin 52 is inserted into the bowl-shaped recess 71 of the punch head 7, and its tip is pivotally supported at the bottom. Furthermore, the push rail 5 is in the upper ridge region,
It is provided with a pin 51 protruding toward the end face side and inserted in a hole 35 provided in a side plate 36 of the pressing plate 3 with play. The function of the pin 51 is to maintain contact between the push rail 5 and the push plate 3 should the punching die 4 become stuck in the document. When the push plate 3 is operated, the push rail 5 causes the punching die 4 even on the lower surface of the push plate 3.
Since it does not slide in the head 7 of FIG. 3 and merely performs a tilting movement, the force transmission from the push plate 3 to the punching die 4 is performed without loss. The punching die 4 is surrounded by a coil spring 6. The lower end of the coil spring 6 is supported by the horizontal portion of the lower portion of the document punch,
The upper end is supported by the annular shoulder of the head 7 of the punching die 4.
