    • A wind and course calculator for navigation is provided comprising two superimposed disks made from a transparent material, a mobile disk 1 movable in rotation and in translation carrying a network of concentric circles corresponding to the speeds and of converging straight lines corresponding to the angular values of headings and a supporting disk 2 having a mark 5 indicating the heading and, at its periphery, graduations corresponding to the angular values of sailing trims of the boat and a scale of speeds 7 carried on the radius directed towards the indication of the heading, on the reverse side of which supporting disk is fixed a pointer 10, 11 having a slider 12 carrying a reference dot 13 serving as display and reading point. The upper face of the supporting disk has two parallel guides 3 between which the mobile disk 1 slides.This calculator is more particularly provided for use by competitors in sailing regatas for readily determining the surface wind, the heading to take, the basic course and the future surface wind related to the evolution of the current.
    • 提供用于导航的风和航向计算器,其包括由透明材料制成的两个叠加的盘,可移动的移动盘1,其可旋转移动,并且平移地携带对应于速度的同心圆网络,并且与对应于速度的 标题和支撑盘2,其具有指示航向的标记5,并且在其外围处具有对应于船的帆船装饰的角度值的刻度和在朝向标题的指示的半径上承载的速度等级7上 支撑盘的相反侧固定有指示器10,11,其具有带有用作显示和读取点的参考点13的滑块12。 支撑盘的上表面具有两个平行的引导件3,移动盘1在其之间滑动。 该计算器更具体地提供给竞争对手在帆船赛场中使用,用于容易地确定与当前演变相关的表面风,取向,基本路线和未来地面风。

    • The rotatable wheel assembly includes a wheel member rotatably sandwiched between a pair of cover members. Grommetless securing means are provided on at least one of the cover members for securing it to the other cover member through an axial opening in the wheel member. The grommetless securing means, which in one embodiment constitute an adhesive patch formed on at least one of the cover members, also function as a pivot for rotation of the wheel member with respect to the cover members. In other embodiments of the invention, the grommetless securing means comprise an adhesive patch member, which can be formed as an appendage to one of the cover members, that spans an opening in one of the cover members to adhere to the other cover member through the axial wheel opening. In a further embodiment of the invention the grommetless securing means comprise tab members formed on one of the cover members to extend through the axial wheel opening and a tab reception opening in the other cover member for folding thereon. A sheet construction for the rotatable wheel assembly includes the wheel member and cover member in side-by-side relationship with separation and fold lines to facilitate arrangement of the construction into a rotatable wheel assembly. Mass production of the construction blank can be accomplished on a web wherein all separation and fold lines lie in the direction of movement of the web.
    • 可旋转轮组件包括可旋转地夹在一对盖构件之间的轮构件。 至少一个盖构件上设有无轨道固定装置,用于通过车轮构件中的轴向开口固定到另一盖构件。 在一个实施例中,构成形成在至少一个盖构件上的粘合贴片的无索引固定装置也用作轮构件相对于盖构件旋转的枢轴。 在本发明的其它实施例中,无套索固定装置包括一粘接贴片构件,该粘合贴片构件可以形成为一个盖构件的附属物,跨接在一个盖构件中的一个开口,以通过 轴向轮开度。 在本发明的另一个实施例中,无套索固定装置包括形成在一个盖构件上的突出构件,以延伸穿过轴向车轮开口和另一个盖构件中的用于折叠的接片开口。 用于可旋转轮组件的片材结构包括与分离和折叠线并排关系的轮构件和盖构件,以便于将构造布置到可旋转轮组件中。 施工坯料的大规模生产可以在网上完成,其中所有分离和折叠线位于幅材的移动方向上。
