Description

Limb tab

The invention relates to a collapsible folding rule, also called a folding rule, made of wood, brass, plastic or other material, as it is mainly used in the construction industry, in trade and industry, but also in the private sector for measuring in the metric system.

It is common to use tape measures made of textile or metal material with an automatic rewinder for measuring in the metric system. In certain industries, it is common to use a folding ruler as described above.

In the case of the folding rules known to man, the centimeter divisions are either marked on both sides when closed on the top left-hand side of the rule, starting with cm 1, which means that the rule must be opened from top to bottom when measuring. This has the disadvantage that if the rule is not fully opened, for example if only short distances are to be measured, the opened sections do not lie flat but hang in the air, which can lead to measurement inaccuracies, and the result is that you have to re-measure several times.
Or the centimeter division starts in the opened position on the lowest link from the left with cm 1 to the right continuously up to cm 200, as proposed in GBM 296 04 255.2, which allows for precise measuring. This folding rule is opened from bottom to top. In both cases, the folding rule can only be read in one direction.

The invention presented in the claims is based on the problem of developing a folding rule

kel, which can be laid flat like a tape measure when measuring and can be read from both sides simultaneously starting from cm 1. This has the advantage, among other things, that you don't have to turn and twist the folding ruler, but can read the measurement accurately from any position. You can also lay the folding ruler at an angle on a corner and read from both resulting sides starting from cm 1.

The invention is set out in the claims and will be explained in more detail with reference to a drawing.

Figure 1 shows the opened folding rule 1 with the lowest section 2, on which the centimeter division is applied on the lower edge from the left outside with cm 1 to the right continuously over all sections up to cm 200 on the top section (3) and on the upper edge opposite is labeled in mirror writing with cm 200 counting down to cm 1. The section 3 on top can be seen as the last section.

The folding ruler can be opened from both sides, depending on the position from which you want to measure.

Claims (2)

Protection claims: 1. Folding rule, the segments of which are connected in a known manner at a distance of 20 cm by a rivet that can be rotated around the rivet axis and are folded together in an accordion-like manner to form a package, characterized in that all segments are provided with a continuous double centimeter graduation, whereby the centimeter graduation is applied on the lower edge of the lowest segment (2) of the folding rule (1) in the open state from the left outside with cm 1 to the right continuously over all segments up to cm 200 on the top segment (3) and opposite on the upper edge of the lowest segment (2) in mirror writing from the left outside with cm 200 to the right continuously counting backwards to cm 1. 2. 20 Folding rule according to claim 1, characterized in that the proposed centimeter division is applied on both sides, i.e. on the top and bottom of the folding rule (l).
