Problems solved by technology

[0003] Accordingly, the staplers of the prior art have the problem that they require a large installation space due to the lever and / or, as in staplers, allow only a small insertion depth of the sheets

Embodiment Construction

[0012] FIG. 1 shows a stapler including its lower part 1, which is preferably but not necessarily formed as a base, an upper part 2 fixed on the lower part so that it can pivotally move at the rear end in the embodiment shown. and a lever 3 connected to the upper part 2 at its free end, which in lever mode projects upwards from the upper part 2 so that an angle is formed between the upper part 2 and the lever 3 . FIG. 2 shows the stapler at the end of the stapling process, also in lever mode, wherein the upper part 2 has been pressed down onto the lower part 1 by means of the lever 3 . Here too, the angle between upper part 2 and lever 3 has been reduced.

[0013] FIGS. 3 and 4 show the stapler in the basic mode, that is to say with the lever 3 deactivated, which therefore rests against the upper part 2 . Figure 3 shows the moment before the binding process starts. This is also where you can place or store your stapler in a space-saving manner. Subsequently, by pressing the...

Abstract

A stapler having a base part (1) and a top part (2) pivotally connected to the same, the free end (E) of which can be pushed down (lever mode) onto the base part (1) via a lever (3) for the force-reducing driving of a staple into a material to be stapled that is positioned on the base part (1), is configured according to the invention such that the stapler can be utilized for stapling without any lever force amplification in a second operating mode (base mode), and the lever (3) is placed on and fixed to the top part for this purpose. The stapling occurs via pressure that is exerted onto the free end (E) of the top part (2). A fixing element secures the selected mode. The lever (3) and / or the top part (2) may have an operating button (4) for changing between the lever mode and the base mode.

Description

technical field [0001] The invention relates to a stapler comprising a lower part, which is generally formed as a base, and an upper part, which is generally pivotably fastened to the rear end of the lower part. A magazine for staples is usually located on the upper part. By pressing the front free end of the upper part down onto the lower part, the staples can each be pressed into binding objects, for example a stack of papers, located on the lower part in order to bind them together. When the stack is thick or the paper is stiff, it may be difficult to apply the necessary binding force by pressing the upper part directly. Background technique [0002] Staplers have thus been developed in which the binding force is applied not by directly pressing the upper part, but indirectly by means of a lever. Publications of US-PS 7,140,526, Japanese Utility Model 2084404, US-OS 2002 / 0005427 A1 and International Application WO 03 / 082528 A1 show such devices, for example. Furthermor...
