Slide rule

The invention relates to a slide rule for determining certain data on growth in size, in particular the growth in height of children in relation to corresponding average sizes.

Child growth is usually measured in terms of a mean, with corresponding Mean values are available in tables, which are assigned to the respective ages for girls and boys Have values for height and weight. The average values are statistically derived from the corresponding population determined. For children there is particular in the UK area the so-called "Tanner tables", with the Average values of children of the third social class from the early 1960s were determined?

the values for height and weight are given as percentages for successive ages specified. In the Tanner tables, selected percentages, especially the 3rd, 10th, 25th, 50th, 75th 90th and 97th, so that each value shown in the table is a height or a body weight indicates that by a certain percentage of boys or girls in a certain Age is exceeded.

It is also known to graph the mean height and weight values of children, again being the height or weight in selected percentages based on the age of from birth to adulthood. The weight or the size of a child is included plotted graphically against age in the graph.

It is known that tables of this type or such graphical representations are not the most practical form of determining possibilities in this regard. Data recorded in this way are only meaningful for interested persons, e.g. for doctors.

The invention seeks to create a way to use the relevant data and its results, i.e. the growth behavior of children is easily accessible to a broader group of people to do, e.g. for parents and similar interested laypeople.

The invention provides a slide rule for this purpose with the features according to claim 1.

The device according to the invention can be recognized according to Art a slide rule and the type of use results essentially from the assignment certain scales for certain elements of the calculator. The computer is expedient on the basis of existing ones Size growth tables are set up and the size parameter of the second scale is therefore either the Height or weight. Since both height and weight are used to record the growth of Children are important, wear either the first or the second component as a basic element of another row of markings for interaction with a third slide-like element. If one sets according to the relevant Subclaims the slide rule with two movable components, so that one body size and weight can be recorded, then one can also make further gradations and provide indices from Two of the three parts that are not the base part can be worn in order to increase the ratio of body size To record weight or from weight to height for certain fixed ratios.

Of course, variations of the graduation and the marks are also possible. For example A scale and a single mark can be provided showing the percentage of weight or height of a selected combination based on the Represents the mean of the corresponding population.

Further expedient refinements of the invention emerge from the subclaims and from now

following description of an embodiment with reference to the drawing. In the drawing demonstrate:

Fig. 1 to 3 in front view the whole

Slide rule or the two associated slides, and

4 to 6 corresponding views of the

Slide rule or the individual slide from behind.

The slide rule shown has three components 10, 11 and 12, namely a frame 10 in which two slides 11 and 12 can be moved independently of one another are. The frame 10 takes on the two slides in corresponding guides; the slider lie edge to edge in one plane. In the front view, the slide 11 is opposite to the slide 12 of the This is reversed in the upper and in the rear view, as shown in FIGS. 1 and 4.

The frame 10 initially has two rectangular windows 13 and 14, which are located in its longitudinal direction extend the front. These windows are approximately above the middle areas of the slide 11 and 12th

At the longitudinal edges of the windows 13 and 14 are open the frame 10 the respective age reproducing scales 15, 16, 17 and 18 attached, the position of which readily apparent from Fig. 1. The scales 15 and 17 show the ages for boys and the

909 839/0 8

Scales 16 and 18 for girls.

The front surface of the slide 11 also has a scale 19 which passes through the window 13 is visible and interacts with the scales 15 and 16, while a further scale 20 is arranged on the front of the slide 12, which is similar Way is assigned to the window 14. The scales 17 and 18 are calibrated in body size and the scales 19 and 20 in units of weight. The scales 19 and 20 can laterally over their associated slider extend over more than the width of the corresponding window, or starting out repeat from the long edges of the slider.

The frame 10 has two more on its back rectangular windows 21 and 22 (see Fig. 4) located on the area of the sliders 11 and 12, respectively. The frame 10 also has a mark 23 on a longitudinal edge of the window 21 and a further mark on window 22 in a similar manner. The rear surface of the slide 11 has a scale 25, which can be read through the window 21, in the area of the mark 23 and the back of the Slider 12 has a scale 26 in a similar way under the window 22 in the area of the mark 24, where the scales 25 and 26 are percentages of height relative to age and percentages, respectively of weight to show age »

When using this slide rule on a child with known gender, age, height and

909839 / O & 4

Weight becomes the slide 11 within the frame 10 shifted to the corresponding value of the height on the scale 19 with the corresponding Match age on a scale of 15 or 16. The slide 12 is operated in a similar manner shifted to the corresponding body weight according to the scale 20 in accordance with the to bring the appropriate age according to the scales 17 or 18. The whole slide rule is then turned over, so that it can be viewed according to FIG. 4 and at the markings 23 and 24 one can then the percentage size based on the age or the percentage weight based on the Read off the age for the child population to which the slide rule is adjusted.

Further data are available on the back of the computer through two rectangular windows 27 and 28 in the Bracket 10 and each on the slide 11 and 12 are available. These are recognizable as elongated designed window formed transversely to the longitudinal direction of the slide rule. The bracket 10 carries scales 29 and 30 on the long sides of the windows 27 and 28, respectively. The backs of the slider 11 and 12 each have two series of graphs 31, 32 or 33 and 34, which are selected percentages of the corresponding male and female child "populations". The graphic Representations 31, 32, 33 and 34 can also be differentiated from one another by color, which is indicated in the drawing by using solid and dashed lines. If the Slider in the holder in the one described above

909839/0849

Manner, shows the respective age on the scales 29 or 30 with reference to the Traces or graphs 31 or 32 or or 34, which percentage or which percentages of height or weight on or in between.

Further data on height and weight are available on the front of the slide rule: A further rectangular window 35 is arranged there in such a way that it encompasses the edges lying against one another of the two slides 11 and 12 in a certain Uncovered displacement area. The slide 11 carries while in the area of this window a mark 36 on its relevant edge and the other slide 12 has a scale 37 on its edge which shows a percentage distribution of weight against the Body size is. With the appropriate adjustment to the given body weight, height and age in the way described above is obtained by setting the mark 36 with respect to the scale 37 the percentage weight distribution from weight to height based on the corresponding population.

Of course, the invention is not limited to the local arrangement explained in the exemplary embodiment limited of scales and marks; can analogously Scales are exchanged for markings, and so on. Besides, it is also in the frame of the invention not to evaluate all of the display options shown in the exemplary embodiment.

You can also have graphical representations and corresponding scales between the sliders and 12 let work, for example, a percentage statement about the ratio of weight to get height. Of course, other units of measurement can also be used, e.g. alternatively metric and inch dimensions.
