DE202010015229U1 - Coupling device for cutting pads - Google Patents

Abstract

A coupling device for cutting pads, comprising a first and a second mat (10, 30) provided with a grid pattern and a scale and at least at one corner with a coupling element (15, 35) and at least one coupling piece (50), which in two adjacent coupling elements (15, 35) of the mats (10, 30) engages to immovably connect them together.

Description

Background of the invention

(a) Field of the invention

The The invention relates to a coupling device with which several cutting pads can be connected without affecting the connection during the cutting process.

(b) Description of the current state of the technique

Cutting boards be as their name implies as a document on a table or put another flat surface when using paper with a knife should be cut.

The US Pat. 4,192,494 Mima describes a typical cutting pad made of a hard synthetic resin and its manufacture.

There However, such cutting documents a defined size but no coupling options for connection with others Cutting documents have regularly occur problems on when pieces of paper that are the size exceed the cutting pad to be cut.

The US Pat. 7,250,207 describes a cutting pad in which magnets are incorporated in the lateral boundary surfaces, which hold together adjacent cutting pads.

The however, the required number of magnets increases the manufacturing costs considerable and besides are the holding forces Often the magnets are not sufficient, so the plates are apart drift.

Detailed description the preferred embodiment

1 to 3 show a cutting pad with inventive coupling device. It contains two mats ( 10 . 30 ), both with right-angled marking lines ( 11 . 31 ) at a defined distance, between which at the edges ( 13 . 33 ) Scaling marks are attached. Lining and scaling are not part of the invention and are therefore not described below.

The mats ( 10 . 30 ) each have four corner areas ( 14 . 34 ) with a coupling element formed therein ( 15 . 35 ), each having an interior area ( 16 . 36 ) and a neck area ( 17 . 37 ) Has. There are also U-shaped couplings ( 50 ) with outward pointing fingers ( 51 . 52 ) for connection to the coupling elements ( 15 . 35 ) of the mats ( 10 . 30 ) and serve to their stable connection with each other.

The coupling pieces ( 50 ), for example, two ( 1 to 6 ) or four ( 5 ) outward pointing fingers ( 51 . 52 ) to have. The shape of the fingers corresponds to the coupling elements ( 15 . 35 ) or at least similar to a stable connection of the mats ( 10 . 30 ) to ensure.

It should be pointed out that the fingers ( 51 . 52 ) of the coupling pieces ( 50 ) a wider outer piece ( 53 ) and a narrower inner piece ( 54 ), what the larger interior areas ( 16 . 36 ) and the smaller neck areas ( 17 . 37 ) of the mats ( 10 . 30 ) and so a well fitting connection with the coupling elements ( 15 . 35 ). The finger ( 51 . 52 ) should be the same thickness as the mats ( 10 . 30 ) in order to avoid a step between them so that a sheet of paper ( 90 ) can lie flat ( 6 ).

For use, the mats ( 10 . 30 ) either with the longer ones ( 1 to 3 ) or with the shorter pages ( 4 ) next to each other or more than two mats ( 10 . 30 ) placed next to each other when a larger cutting surface is needed. 6 shows like a piece of paper ( 90 ) on two or more coupled mats ( 10 . 30 ), which in turn sits on a table surface ( 91 ) so that the user ( 80 ) with a knife ( 92 ) can trim.
