Definitions
- This invention relates to a method and a device for testing cross-country skis.
- the span pressure may vary from 20 to 120 kg for the same ski length of the same manufacture. Due to differences in the span pressure the skis will have different properties for ski runners of different weight.
- ski-wax will be quickly worn off under the hold.
- the method generally used at present to test the span pressure consists of "pressing"on the skis manually.
- this method provides an uncertain result, which is unsatisfactory for the ski runner.
- a device according to the invention which comprises two bars 1 (one hidden in the figure), which can consist of U-profiles of e.g. aluminium.
- Each bar 1 is provided with a number of microswitches 2, which are uniformly spaced along the bar 1.
- Each microswitch 2 is connected to a lamp 4 on a control board 5 via a cable 3.
- the lamps 4 are preferably arranged in a row after each other (see Fig.).
- the microswit ches 2 function e . g . in such a way that when a ski is depressed to contact with a microswitch a power circuit will be closed, the lamp 4 on the panel 5 connected with the microswitch 2 being lit.
- the bars 1 are also provided with a device for measuring the span height of the skis being tested.
- This device e.g. consists of a potentiometer 6, which is located about in the middle of the bar in its longitudinal direction.
- the potentiometer 6 is also via the cable 3 connected to an indication means on the board 5.
- the indication means is a pointer instrument 7, which thus indicates the height of the span directly, e.g. in mm.
- the person 9 then steps onto the skis 8 and places his feet in the positions of the skis which will be entered in running. At the person's 9 load on the skis 8 they will be depressed to contact with the bars 1 in their outer portions as seen in the longitudinal direction, the microswitches 2 arranged in the bars being actuated to close the associated power circuit and to light the corresponding lamp 4 on the board 5.
- the number of lamps not being alit it is simple to calculate the length of the span when the constant distance between the microswitches is known. Information about the position of the span in the longitudinal direction of the ski is also obtained by. observing which lamps are not alit. Then it is very easy to mark the extension of the span on the skis, which is important information for applying ski-wax for hold and glide.
- the height of the span in loaded position of the skis 8 is read directly on the pointer instrument 7.
- the interpretation of the information obtained can be facilitated by using keys to a code of different types, which can preferably be arranged on the board 5.
- the board 5 is placed on a stand (not shown in the figure) in order to obtain a suitable reading height for the person testing the skis and also for the seller of the skis.

Abstract
Dispositif d'essai de skis de fond. La rigidite d'un ski de fond varie en fonction du poids du skieur ainsi que de la technique de ce dernier. L'objet de la presente invention est de fournir un dispositif permettant d'essayer une paire de skis de fond d'une maniere simple. Le dispositif comprend une paire de barres (1), sur lesquelles on place la paire de skis (8) a essayer. Le dispositif comprend aussi des moyens de sonde (2, 6) pourvus dans lesdites barres (1) et relies a un tableau de controle (5) Lorsque le skieur pose ses pieds sur les skis (8), ils sont presses contre les barres (1), et les moyens de sonde (2, 6) enregistrent la portee des skis (8) sur les barres (1). Ceci produit des informations sur le tableau de controle (5) quant a la longueur, la hauteur et la position de la portee entre les deux points d'appui a vide, dans le sens longitudinal du ski. Au moyen de cette information on peut determiner rapidement et simplement si les skis essayes conviennent au skieur.
