    Description
    Orienteering Compass
    The present invention relates to a compass for orientation.
    In orientation sports, three types of compasses are mainly used; traditional rectangular orientation compass, here called a linear compass, with rotatable compass housing, thumb compass, and wrist compass. Common compasses can be seen at, for example, www.silva.se. www.suunto. com, www.letro.se.
    To take a compass course with a linear compass goes as follows: The compass is placed on the map so that its long side or a marked course line runs in or parallel to the course direction on the map, after which the compass housing is rotated so that the marking lines in the compass house run parallel to the meridians of the map. Furthermore, it must be ensured that the north marking in the compass housing points towards the map's north. The compass is then removed from the map whereby the orientator rotates and the compass so that its north face coincides with the compass's north marking. When the compass is held in this position, its longitudinal sides and course lines point to the correct compass course in the terrain.
    The above procedure is relatively cumbersome and time consuming for competition orientation, which is to the great disadvantage of the ruler compass.
    One of the advantages of the ruler compass compared to the thumb compass is the ruler compass is poured in one hand and the map in the other. The compass is thus not in the way of reading the map and the orienter can pour the thumb grip on the map, ie use the garden as a position marker and gradually move the thumb to its current position on the map.
    The thumb compass is nowadays supposed to be the most popular type among competition orienteers. Its basic design and handling of patent application SE8100133-1. The design of the thumb compass has been improved and varied. There are variants with rotatable compass housing and sockets, ie elongated heel or U-shaped socket in the bottom plate, for the thumb for better grip on the map, among other things according to patent application SE8802843-6.
    When using thumb compass, it is not the thumb, but part of the compass that is used as a marker of the current position on the map.
    The advantages of the Tili inch compass can be mentioned the rapid selection of the compass course and that it is in the same field of view as the map, which offers more continuous control of the course in connection with map reading.
    One of the disadvantages of the thumb compass is that the compass itself partially obscures the map during map reading. The compass course line coincides with a beveled edge of the compass base plate. This edge is usually placed on the map on the line between the starting point and the middle point. (The procedure is detailed in patent application SE8100133-1.) Details on the map to the left of this line (for compass intended for left hand) thus fall below the compass's bottom plate and its beveled edge which obscures details on the map. Alternatively, the user may place the beveled edge of the compass parallel to the line on the map, or in its extension behind it, but there is another problem, namely that the compass no longer marks the position of the orientation on the map.

    The outermost side edge of the thumb compass (the one against the hand and forefinger) and any slant or socket for the thumb do not run in the same direction as the course line, but are usually 20 to 45 degrees oblique in relation to the course line. In other words, the instructor does not know the course direction in his hand. This is in contrast to the linear compass whose long sides run in the same direction as the compass course, so that the informant not only sees the course, but also feels the compass course in the hand of the longitudinal sides of the compass. The fact that the edges of the thumb compass tend to be skewed in relation to the course line may be perceived by some as depressed and to the detriment of the thumb compass.
    A wrist compass is fastened with strap straps on the back of the hand or the thumb top. So it does not lie on the map. This type of compass offers the benefits of reading in the same field of view as the map, and being able to use the thumb as a position marker. However, the obvious disadvantage is that it does not like to determine compass course with any greater precision, but only approximate aiming by matching the map north to north according to the north viewer.
    In addition to the above-mentioned compass types, there may also be mentioned mirror compass which is basically a linear compass provided with a visual aid to visually aim the compass course in the terrain with greater precision.
    The object of the present invention is to provide a compass that eliminates the above-mentioned disadvantages of the thumb compass, that the thumb compass partially obscures the map when reading the map, and that the thumbscope mass does not always function as a marker of the current position, and to provide a compass that is convenient to tilt and lies firmly on the map, has a course pointer for clear visual aiming of the course direction in the terrain, and has a geometry that engenders a sense of the course direction when held in the hand.
    The invention is described in more detail below with reference to the accompanying drawings:
    Figure 1a: Top view of compass in one embodiment of the present invention where the compass is to be poured into the left hand
    Figure 1b: Vybaki view of compass in one embodiment of the present invention where the compass is to be poured into the left hand
    Figure 2: Illustration of handling the compass with map
    Figure 3: Alternative version where the compass is to be poured in the right hand
    Figure 4: Alternative version where the compass has two parallel la support edges for the thumb
    The compass according to the invention is intended to be attached to the thumb and poured into the same hand as the map. As a precursor to Figures 1a and 1b, the compass consists of bottom plate (1), compass housing (2) with north face (3), support for thumb (4), travel strap (5, 6) and a fixed mounted course pointer (7). The compass housing is of known design, transparent and suitably filled with damping fluid. In the compass housing is a magnetic north face mounted freely rotatable.
    To attach the compass to the thumb, it is provided with one or two travel straps of adjustable length (5) and (6).
    The course pointer (7) is arranged in such a way that it is always fixed in relation to the base plate, and mounted in such a way that it protrudes outside the compass housing (2) and the base plate (1). This protruding part of the course pointer is placed in the desired course direction on the map when selecting a compass course and in this step has the same function as the rabbit (ruler) on the thumb compass and the ruler compass.
    20180146 prh 28 -12- 2018
    The handling of the compass and placement on the map when selecting a compass course is shown in Figure 2. The orientator pours the map and the compass horizontally and places the cursor above its own current position on the map and on the (imagined) line towards the next target on the map. As shown in Figure 2, the map is visible on both sides of this line on the map, which would not have been the case when using known types of thumb compass.
    In the embodiment according to figure 1b, the course pointer (7) is placed above the compass housing (2), which allows the user to perceive a detail on the map under the course pointer thanks to the fact that the right and left eyes view this detail obliquely from the side from each pour. (This effect is not illustrated.) The user can also flick the map and compass from the horizontal plane to temporarily view the area under the course pointer from one pour.
    The course pointer (7) is preferably made of a flexible and resilient material, a polymer or composed of several polymers or polymer reinforced with other material, so that it can bend and spring back without being cracked or deformed.
    As shown in Figure 2, the compass is affixed to the thumb with a travel strap, and the compass and map are poured between the thumb and fingers. The thumb is slightly bent and the front of the thumb abuts against both the map and one of the edges of the bottom plate (9 in embodiments according to figure 1a) which is parallel to the course pointer (7 in figure 1a), and towards the edge of the bottom plate (1i in figure 1a) which is perpendicular to the course pointer. The index finger and part of the palm may, but need not, abut the outer side edge of the base plate (10 in Figure 1). As shown in Figure 1, the thumb support edge (9) and the bottom side edge (10) of the base plate are parallel to the course pointer (7) and thus run in the heading direction when the compass course has been taken out. Furthermore, the edge of the base plate at the thumb (11) is perpendicular to the course pointer. This fact, that said edges are in the same direction as, respectively perpendicular to, the direction of the course, makes the orientator feel the heading direction of the thumb and hand.
    The compass according to Figures 1a and 1b is provided with a support (4) for the thumb, so that the inner part of the thumb is also used to clamp the compass against the map as the compass and map are poured between the thumb and the fingers. The purpose of this support is to hold the compass firmly against the map without effort. The support (4) is mounted on the base plate in the embodiment according to Figure 1, but may in an alternative embodiment be a raised part of the base plate itself.
    The compass according to figure 1 is intended to be poured into the left hand. Figure 3 illustrates an alternative embodiment for the right hand where the compass has a mirrored appearance compared to Figure 1. Figure 4 illustrates an alternative embodiment where the base plate is designed to form an additional support edge (12) for the thumb on the side of the thumb closest to the course pointer. . This support edge (12) is also parallel to the course pointer.
    The compass according to the invention can be varied in several respects within the scope of the claims, inter alia with respect to the other geometric design of the base plate, with respect to the position of the course pointer and in the way it is applied to the compass, with respect to the design of travel straps for the thumb.
    Furthermore, in a further alternative embodiment, the compass according to the invention can be provided with a rotatable compass housing instead of a fixed one. In this embodiment, the course pointer is applied in such a way that it is still fixed in relation to the base plate but so that the compass housing can be rotated (not illustrated).
    Common to all embodiments is that the course pointer (7) protrudes outside the compass housing and the front edge of the base plate (8), that the support edge (9) of the thumb and the outer side edge (10) of the base plate are parallel to the course pointer (7), and that there is a raised support ( 4) below the inner part of the thumb.
    It will be apparent to one skilled in the art that many changes and combinations may be made by the embodiments described above without departing from the spirit of the invention. Thus, the invention should not be limited by the described embodiments but may be varied within the scope of the claims.
