Description

Title; Tape measure with currency converter

The innovation relates to a tape measure or a measuring tape of this kind which has a scale on a first side. Tape measures of this known type have the advantage that they are simple in construction and use. However, such measuring tapes only have one puncture.

/ For different currency units that have a relatively fixed mutual exchange rate, converting them is often a difficult and time-consuming task. In addition, there is a high risk of making mistakes. The present innovation aims to create a device for converting such currency units, whereby the disadvantages mentioned are avoided. For this purpose, a device according to the innovation is characterized by the features according to claim 1.

By providing a measuring tape with a scale on a first side, e.g. in centimeters, and with at least two scales for currency units with a relatively fixed mutual exchange rate on the opposite side, a tape measure with a double function is obtained, whereby it is easy to read how much a first currency is worth, expressed in at least one other currency which is indicated thereon.

This simply avoids errors and difficult calculations, while the device takes up little space. Such a device is particularly suitable for use when converting the national currencies of European countries into euros and vice versa.

In a particularly advantageous embodiment, a device according to the innovation is characterized by the features of claim 2. Such a tape measure offers the advantage that during use the measuring tape can be pulled out of the housing by a suitable distance, in such a way that

that the amount to be converted can be read in the window, as well as the currency being converted. In addition, such a tape measure has the advantage that the measuring tape can be stored in the case.

To make things clearer, the new feature is explained in more detail using the drawing. It shows:

Fig. 1 is a perspective view of a rolling measure according to the innovation,

Fig. 2 a part of a measuring tape according to the innovation, seen from below, and

Fig. 3 a part of the measuring tape, seen through a window in the tape measure.

A tape measure (1) according to the innovation comprises a housing (2) in which a relatively flexible measuring tape (3) can be rolled up, in the usual way with the help of a spring mechanism (not shown). On the top of the measuring tape, i.e. on the side facing the inside of the housing when rolled up, there is a scale division

(4) is provided, e.g. with a usual classification into

Millimeters, centimeters, meters and/or inches. A window (5) is provided in the housing (2) through which the measuring tape O) is at least partially visible. This window

(5) is shown in more detail in Fig. 3.

On the underside of the measuring tape (3), as shown in Fig. 2, a number of scale divisions (6) for different currency units are positioned next to each other. In the embodiment shown, a first scale division (6A) shows a division in Dutch guilders (cents), while a scale division (6B) closest to it shows euros (euro cents). The scale divisions are preferably positioned in such a way that the converted value of this in euros is always indicated next to an amount in guilders. Of course, other currency units can be indicated as desired, if necessary in a series of scale divisions next to each other. In the window (5)

a vernier or similar reading device is attached, e.g. in the form of a horizontal line (7). This makes it easy to read the exchange rate, or at least the conversion amount, through the window (5). This is because the scale divisions (6) are facing outwards in the housing (2) when the measuring tape (3) is fully or partially unrolled. By unrolling the measuring tape (5) until the desired amount in guilders, for example, has been brought under the reading line (7), the amount converted into euros can be read directly under the same line. It will be clear that many modifications are possible within the scope of the innovation. The measuring tape can be designed as a collapsible or foldable measuring tape, like a folding rule or ruler, while other sizes can also be indicated in conversion scales.

These and many similar modifications are not considered to exceed the scope of innovation.

Claims (2)

EXPECTATIONS 1. A tape measure or similar measuring tape, wherein a measuring graduation is preferably provided on a first side of the measuring tape and wherein at least two scales for currency units are provided on the opposite side, which scales are positioned relative to one another on the basis of the exchange rate of the respective currency units, all in such a way that when at least part of the measuring tape is pulled out, the value of at least one of the currency units can be read in relation to at least one other currency unit. 2. Tape measure according to claim 1, provided with a housing and a measuring tape that can preferably be rolled up in the housing, the housing being provided with a window for reading currency units and ratios therebetween, the window preferably being provided with a vernier or a similar reading means.
