Writing unit with punching

Description

The invention relates to a writing unit according to the preamble of claim 1.

It is known to provide the individual sheets of a writing unit, in particular a writing pad or writing notebook, with a perforation for easier separation.

BUD104 Page 2

For example, to tear out a sheet of paper from a spiral notepad, the thumb of the left hand presses the strip of paper to the left of the perforation onto the stack of paper underneath. The sheet is then torn off by grasping it between the thumb and index finger of the right hand and pulling it from top to bottom. What remains is a strip of paper that is bound in the spiral binding.

The sheets of a writing unit are separated in the same way, the individual sheets of which are connected to one another at the top by staples and have a horizontal perforation. Here too, additional pressure on the paper strip above the perforation is required to enable a sheet to be separated safely.

Many people are unable to use the two-handed technique described above, so that the strip of paper on the side that is supposed to remain on the writing unit is often torn off, or the sheet of paper that is to be torn off even breaks. Often, for example, when making a phone call, both hands are not available, so that a sheet of paper has to be torn off with one hand.

The invention is based on the object of providing a writing unit that enables individual sheets of paper to be torn out of the writing unit safely and easily with just one hand.

This object is achieved according to the invention by a writing unit with the features of claim 1.

BÜD104 Page 3

By providing a punch at one end of the perforation, a tear-off aid is created that allows a single sheet to be torn off safely and reliably, even with one hand. It is precisely the beginning of the tear-off process that is problematic. If the tear-off process does not begin at one end of the perforation, it is almost inevitable that the sheet will not be torn out properly and that the sheet may even be partially destroyed. By making the punch at one end of the perforation, it is ensured that the beginning of the tear-off process takes place safely at the perforation.

A writing unit within the meaning of the invention is to be understood in particular as writing pads, tear-off pads and writing books the pages of which can be torn out of the writing book or where parts of the pages, such as side control strips, can be torn out of the writing book.

The punch is preferably wedge-shaped, rectangular or in the shape of a keyhole. The punch is either located at one end of the perforation or at both ends. Providing the punch at both ends is particularly advantageous for left-handed people, as they often tear off in the opposite direction.

Depending on whether the individual sheets of the writing unit are connected at the top of the writing unit or at the left or right side of the writing unit, the perforation is preferably located on the top left

BUD104 Page 4

or right-hand side of the sheet and the punching accordingly at the right and/or left end or at the top and/or bottom end of the perforation.

A writing unit according to the invention is preferably a spiral paper pad, in particular a spiral notepad, a spiral school pad, a spiral steno pad or a college pad, a folded paper pad, in particular a folded notepad, a bound paper pad, a stapled paper pad, a lined or squared school exercise book or an exercise book.

Advantageous and preferred embodiments of the invention are characterized in the subclaims.

The invention will be explained in more detail below with reference to the figures of the drawings and several exemplary embodiments.

Show it:

Figure 1 shows a writing unit according to the invention with lateral spiral binding;

Figure 2 shows a writing unit according to the invention with spiral binding arranged at the top;

Figure 3 shows a writing pad according to the invention, the sheets of which are stapled at the top;

BÜD104

Figure 4 shows a school notebook according to the invention with detachable sheets and

Figure 5 shows an exercise book according to the invention with detachable side strips.

Figure 1 shows a notepad 1 with a spiral binding 2 arranged on the side. For this purpose, a spiral 3 runs in a known manner through small, vertically arranged holes 4 in the individual sheets 5 of the notepad 1 and thereby connects the individual sheets. At a distance of approx. 1 cm from the left side edge of a sheet 5, a micro-perforation 6 runs vertically at a distance from the holes 4 of the spiral binding 2. At the upper end of the micro-perforation 6 there is a keyhole-shaped punch 7. The sheet 5 also has holes 8 in a known manner for later filing the sheet in a folder.

A sheet 5 of the college pad 1 can be torn off with one hand. To do this, the sheet 5 to be torn off is grasped with the thumb and index finger of the right hand, particularly at the top right edge, and then pulled from top to bottom. The punch 7 initiates the tearing process at the perforation without any problem and the individual sheet 5 is torn out safely without additional counter pressure on the left edge, for example with the thumb of the left hand. The sheet 5 is torn out safely with one hand without the side strip penetrated by the spiral 6 being torn off.

BUD104 Page 6

between micro-perforation 6 and the left edge of the spiral 3, and also without the sheet 5 itself being damaged during the tearing process.

Figure 2 shows a spiral pad 10 in which the spiral binding 12 is arranged at the top. For this purpose, a spiral 13 runs through holes 14 to loosely connect the individual sheets. A micro-perforation 16 runs horizontally from the left edge to the right edge of the sheets 15 of the spiral pad 11. A rectangular punched hole 17a, 17b is arranged at each end of the perforation 16.

A single sheet 15 is torn out by grasping the sheet 15 in the right or left area and pulling this sheet from right to left or left to right. Due to the punching 17a, 17b, the separation process is initiated cleanly and in a defined manner, so that the sheet 15 can be safely torn out one-handed.

A left-handed person will usually separate from right to left and a right-handed person will usually separate from left to right.

Figure 3 shows a writing pad 21, the sheets of which are connected to one another in the upper area by several staples 2 2. The upper area of the writing pad 21 is covered with an adhesive strip to cover the staples. Similar to the arrangement in Figure 2, a micro-perforation 2 6 runs horizontally below the staples 22 from the left to the right edge of each sheet 25

BUD104

of the writing pad 21. Rectangular notches 27a, 27b are provided at each end of the perforation as a tear-off aid.

Figure 4 shows a lined exercise book 31 in an open state. The individual double sheets of the exercise book 31 are connected to one another by staples 32 along the middle of the exercise book 33. A perforation 36 runs along the side of the middle of the exercise book 33, whereby the perforations 36 lie one above the other when the exercise book is closed. In the usual way, holes 38 are also provided for later stapling of the individual sheets 35 of the exercise book 31 into a folder. At the top and bottom of the perforation 36 there is a wedge-shaped notch 37. This tapers from the edge of the exercise book in the direction of the perforation 36.

As in the previous embodiments, the perforation 37 enables a single sheet 35 to be safely torn off from the exercise book 31 using one hand. The tearing process can be carried out either from top to bottom or from bottom to top.

An alternative embodiment of the invention is shown in Figure 5. An exercise book 41 is stapled in the usual way along its center 43 by staples 42. Vertically running perforations 46 define a side strip 48 which can be separated from a sheet 45 of the exercise book 41.

BUD104 Page 8

At the upper end of the perforation 46 there is a tear-off aid 47, which is rectangular in shape. To tear off the side strip 48, which represents a control section for the teacher or parents, the side strip 48 is grasped in its upper area with the thumb and index finger and pulled from top to bottom. The punch 47 initiates the tearing process safely at the perforation, so that the side strip 48 can also be torn off with one hand.

The invention is not limited in its implementation to the embodiments given above. Rather, a number of variants are conceivable which also make use of the invention in fundamentally different implementations.
