Abstract

The device has an orientable planisphere (1) on which contours of various countries are represented, and fixed on a rigid and thin support. A movable index (2) has an axis of rotation exactly located at a location of a holy Mecca city. A compass (3) is fixed on the planisphere in a manner at which north of the compass corresponds to north of a map and its north-south axis is parallel to meridians.

Description

La présente invention concerne un dispositif destiné à trouver laThe present invention relates to a device for finding the

direction de la ville sainte de La Mecque.  direction of the holy city of Mecca.

Les évolutions de notre mode de vie, la nécessité des déplacements qu'elles génèrent et les facilités procurées par les progrès des moyens de transport amènent de nos jours à parcourir notre planète pour de multiples raisons. Le musulman pratiquant qui doit se déplacer bénéficie à ce jour de moyens empiriques, comme la boussole qui nécessite, pour être suffisamment précise, la connaissance de l'angle formé entre la direction du nord magnétique et celle de la ville de La Mecque à partir du lieu où l'on se trouve, ce qui n'est pas évident. Il peut aussi bénéficier de techniques plus évoluées ou d'innovations plus élaborées aboutissant à des créations miniaturisées, délicates d'emploi ou devenant si complexes pour tenir compte d'un maximum de paramètres que leur utilisation en devient vraiment difficile. Tenant compte de ce qui précède, le dispositif présenté se caractérise et se différencie par une grande facilité d'emploi, une précision obtenue suffisante jusqu'aux limites des terres émergées nord et sud, hors zones polaires, ainsi que par un encombrement et un poids ( inférieur à 50 grammes) compatibles avec tout genre de déplacement d'affaires, de tourisme, de randonnée ou autres, et quelles que soient les conditions climatiques ou d'éclairement privant du recours au soleil à fin d'orientation sommaire.  The evolutions of our way of life, the necessity of the displacements which they generate and the facilities provided by the progress of the means of transport bring today to go through our planet for multiple reasons. The practicing Muslim who has to move now benefits from empirical means, like the compass which requires, to be sufficiently precise, the knowledge of the angle formed between the direction of magnetic north and that of the city of Mecca from where you are, which is not obvious. It can also benefit from more advanced techniques or more elaborate innovations resulting in miniaturized creations, difficult to use or becoming so complex to take into account a maximum of parameters that their use becomes really difficult. Taking into account the above, the device presented is characterized and differentiated by a great ease of use, a sufficiently obtained precision to the limits of the lands north and south, out of polar zones, as well as by a congestion and a weight (less than 50 grams) compatible with any kind of business travel, tourism, hiking or other, and whatever the weather or lighting conditions depriving the use of the sun for summary orientation.

Ce dispositif est composé des trois éléments suivants ( voir figure) : d'un planisphère en couleurs (1 de la figure) de dimensions réduites, rectangulaire (29cm X 17cm), sur lequel sont figurés, dans la réalité, les contours des divers pays et fixé sur un support rigide de faible épaisseur.  This device is composed of the following three elements (see figure): a planisphere in color (1 of the figure) of reduced dimensions, rectangular (29cm X 17cm), on which are figured, in reality, the outlines of the various countries and fixed on a rigid support of small thickness.

- d'un index mobile (2 de la figure) transparent, parcouru dans sa longueur et en son milieu par un trait fin et sombre et dont l'axe de rotation se situe précisément à l'emplacement de la ville de La Mecque, sa longueur étant égale à la plus grande demi-longueur oblique du planisphère.  - a movable index (2 of the figure) transparent, traversed in its length and in its middle by a fine and dark line and whose axis of rotation is precisely at the location of the city of Mecca, its length being equal to the largest oblique half-length of the planisphere.

- d'une boussole (3 de la figure) de petite taille et de faible épaisseur, fixée sut- le planisphère de façon à ce que le nord de la boussole corresponde 30 avec le nord de la carte, son axe nord - sud étant parallèle aux méridiens.  - a compass (3 of the figure) of small size and thin, fixed on the planisphere so that the north of the compass corresponds 30 with the north of the map, its north-south axis being parallel at the meridians.

L'utilisation de ce système, d'une très grande facilité puisqu'elle ne nécessite aucune connaissance particulière, consiste à positionner l'index mobile sur le lieu où l'on se trouve, à tourner le planisphère horizontalement jusqu'à ce que l'aiguille aimantée soit sur le nord de la boussole, l'index mobile 35 donnant alors la direction de la ville de La Mecque.  The use of this system, very easy since it requires no special knowledge, is to position the movable index on the place where we are, to turn the planisphere horizontally until the magnetic needle is on the north of the compass, the movable index 35 then giving the direction of the city of Mecca.

Ce mode d'emploi est prévu pour figurer en diverses langues sur le planisphère. Ce dispositif, fiable, léger, transportable, facile d'utilisation, d'une fabrication très aisée et d'un coût modique, couplé ou non aux tapis de prière, est à même de rendre d'importants services aux musulmans pratiquants qui se déplacent.  This manual is intended to appear in various languages on the world map. This device, reliable, lightweight, transportable, easy to use, easy to manufacture and low cost, coupled or not with prayer mats, is able to render important services to practicing Muslims who move .
