Description

[0001] The invention relates to a device for drawing stars.

[0002] A star is a geometric shape with several outer vertices lying on a circumcircle and several inner vertices lying on an inner circle. The outer and inner vertices define distinct points, which are usually arranged symmetrically. Stars are generally considered highly aesthetic, making them popular motifs for coats of arms, flags, logos, and, not least, crafts.

[0003] It is well known that stars can be constructed using a compass and ruler. While a geometrically precise star can be drawn this way, the construction is comparatively time-consuming. Furthermore, star-shaped templates are available, which can be used to trace a specific star. Although using such templates saves time if sufficient accuracy is achieved, drawing different stars requires just as many different templates. This is particularly disadvantageous for hobbyists, as they are generally not interested in mass production but rather in individual craft projects – for example, drawing a star on a small scrap of paper, a piece of fabric, or a wooden disc.

[0004] Against this background, the object of the present invention is to provide a device for drawing stars with which a large number of different stars can be drawn in a simple manner. This object is achieved by a device with the features of claim 1. Further, particularly advantageous embodiments of the invention are disclosed in the respective dependent claims. It should be noted that the features listed individually in the claims can be combined with one another in any technically sensible way and demonstrate further embodiments of the invention. The description further characterizes and specifies the invention, particularly in conjunction with the figures.

[0005] The invention relates to a device for drawing a star with p vertices. p is a natural number greater than 2. The device comprises a flat template body with a support surface and a viewing surface opposite the support surface. The support surface is suitable for placing the template body on a workpiece, for example, a sheet of paper, a piece of leather, a wooden disc, or the like. According to the invention, the template body has a central marking and p first corner openings, wherein the first corner openings are regularly arranged on a first circumcircle around the central marking as the center point. The corner openings are designed such that a suitable marking instrument, for example, a pencil tip or the point of a center punch, can be inserted through them with a substantially precise fit. In this way, a vertex corresponding to the respective corner opening can be created on the workpiece.

[0006] In a preferred embodiment, the template body p has second corner openings, wherein the second corner openings are regularly arranged on a second circumcircle around the central marking as the center point, and wherein the first and second circumcircles have different radii. Preferably, the central marking, a first corner opening, and a second corner opening each lie on a common line.

[0007] In another preferred embodiment, the template body is made of a transparent material. This allows a user of the device to see the workpiece through the template body and align the central marking precisely with the desired position on the workpiece.

[0008] Preferably, the contact surface is flat. In a particularly preferred embodiment, the visible surface is parallel to the contact surface.

[0009] In a further preferred embodiment, the stencil body has markings printed on the visible surface and / or the contact surface to identify the corner openings. The markings can, for example, be colored and / or represent numbers and / or letters. For example, the first and second corner openings are each assigned markings of the same color and / or shape.

[0010] For example, the central marking is printed on the visible surface and / or the contact surface of the stencil body and / or includes a central opening in the stencil body. The central opening is preferably designed so that a suitable fixing device, such as a thumbtack or a pushpin or the like, can be inserted through it with a virtually perfect fit.

[0011] In a further preferred embodiment, the device further comprises a connecting body with a first end face and a first longitudinal surface. The first longitudinal surface and the first end face abut each other, forming a first straight edge. The first straight edge is designed to connect two non-adjacent vertices with a straight line segment. To do this, the first straight edge is placed against two non-adjacent vertices—which, as described above, were previously created using the template body and a suitable marking instrument—and the two vertices are connected with a suitable marking instrument. By repeating this process for each created vertex, a regular star polygon can be drawn onto a workpiece.

[0012] The connecting body preferably has a second end face, which is, for example, arranged opposite the first end face. The first longitudinal surface and the second end face abut each other, forming a straight edge. The connecting body of this embodiment is designed to draw a regular geometric star on a workpiece. For this purpose, the first straight edge is placed at a vertex and the second straight edge at a further vertex not adjacent to the first vertex, and a line of suitable length is drawn on the workpiece using a suitable marking instrument. The vertices were, for example, previously created on a workpiece using the template body and a suitable marking instrument and define the outer corners of the star.If this process is carried out for each created vertex, an intersection point of two lines drawn in this way is obtained between each pair of vertices, with the intersection points each defining an inner corner of the star.

[0013] Preferably, the first and second straight edges are aligned parallel to each other and form a distance between them.

[0014] In a further preferred embodiment, the connecting body comprises a first and a second sub-body, and the two sub-bodies are connected by means of a guide mechanism. For example, the first sub-body comprises the first longitudinal surface and the first end face, and the second sub-body comprises a third end face and a second longitudinal surface. The third end face and a second longitudinal surface abut each other, forming a straight third edge. The first straight edge and the third straight edge are substantially parallel to each other and are spaced apart. The guide mechanism is configured so that the distance between the first straight edge and the third straight edge can be varied while maintaining the parallelism between the first and third edges. The connecting body of this embodiment is designed to trace a regular geometric star on a workpiece.To do this, first set an arbitrary angle between the first and third straight edges and fix, for example, the first and second sub-body using a suitable tool. Then, place the first straight edge at a vertex and the third straight edge at a vertex not directly adjacent to the first. Using a suitable marking tool, draw a line of sufficient length on a workpiece. The vertices, for example, were previously created on a workpiece using the template and a suitable marking tool and define the outer vertices of the star. Repeating this process for each vertex creates an intersection point between two vertices, with each intersection point defining an inner vertex of the star.

[0015] Preferably, the guide gear is designed as a parallelogram guide.

[0016] The invention is explained in more detail with reference to the following figures. These figures are to be understood as examples only and represent preferred embodiments. They show: Fig. 1 a top view of an embodiment of the device according to the invention for drawing stars, Fig. 2 a top view of a first embodiment of a connecting body, Fig. 3 a top view of a second embodiment of a connecting body, Fig. Figures 4 to 7 each show a top view of an embodiment of the device according to the invention comprising a template body and a connecting body.

[0017] Fig. Figure 1 shows a top view of a device 1 according to the invention for drawing a star. An exemplary embodiment for drawing a five-pointed star is shown here; further embodiments with more or fewer than five points can easily be derived from it. The device 1 comprises a flat template body 2 with a support surface 11 and a viewing surface opposite the support surface 11, which is not shown in the view. The template body 2 is a transparent plastic body, which is essentially flat and thus suitable for placing on a workpiece, for example, a sheet of paper, a piece of leather, a wooden disc, or the like. The template body 2 has a central marking 3 and five first corner openings 4a, 4b, 4c, 4d, 4e. The first corner openings 4a, 4b, 4c, 4d, 4e are all located on a first circumcircle, which is shown in the Fig. The central marking 3 is indicated by a dashed line. The corner openings 4a, 4b, 4c, 4d, 4e are designed so that a suitable marking instrument, such as a pencil tip or the point of a center punch, can be inserted through them with a virtually perfect fit. In this way, a corner point corresponding to the respective corner opening can be created on the workpiece.

[0018] As in the Fig. As can be seen in Figure 1, the template body 2 also has five second corner openings 5a, 5b, 5c, 5d, 5e which are regularly arranged on a second circumcircle, indicated by dashed lines in the drawing, around the central mark 3 as the center point. The first and second circumcircles have different radii, and the central mark 3, a first corner opening 4a, and a second corner opening 5a each lie on a common line.

[0019] In the illustrated embodiment of the Fig. 1 includes the central marking 3 a central opening in the stencil body, which is designed so that a suitable fixing means, for example a thumbtack or a pushpin or the like, can be inserted through the opening with a substantially precise fit.

[0020] Fig. Figure 2 shows a top view of a first embodiment of a connecting body 6, which, for example, together with the template body from the Fig. 1 can be used. The connecting body 6 has a first end face 8 and a first longitudinal surface 9. The first longitudinal surface 9 and the first end face 8 abut each other, forming a first straight edge, which is designed to connect two non-adjacent vertices with a straight line segment. For this purpose, the first straight edge is placed at two non-adjacent vertices – which were previously defined, for example, using the template body made of Fig. 1 and a suitable marking tool - and connect the two vertices with a suitable marking tool. If this process is carried out for each created vertex, a regular star polygon can be drawn on a workpiece.

[0021] The connecting body of the Fig. 2 also has a second end face 10, which is arranged opposite the first end face 8. The first longitudinal surface 9 and the second end face 10 are aligned parallel to each other and have a distance a > 0 from each other. The connecting body 6 is thus designed to draw a regular geometric star on a workpiece. To do this, the first straight edge 8 is placed at a vertex and the first straight edge 8 or the second straight edge 10 is placed at another vertex not adjacent to the first vertex, and a line of suitable length is drawn on a workpiece using a suitable marking instrument. The vertices were, for example, previously marked using the template body made of Fig. 1. Using a suitable marking tool, a line is drawn on a workpiece to define the outer vertices of the star. Repeating this process for each vertex creates an intersection point between any two vertices, with each intersection point defining an inner vertex of the star.

[0022] Fig. Figure 3 shows a top view of another embodiment of a connecting body 6. In this example, the connecting body 6 comprises a first sub-body 12 and a second sub-body 13. Both sub-bodies 12 and 13 are connected by a guide mechanism 14, which is designed as a parallelogram guide. The first sub-body 12 comprises a first longitudinal surface 9 and a first end surface 8, which abut each other forming a straight first edge. The second sub-body 13 comprises a third end surface 16 and a second longitudinal surface 15, which abut each other forming a straight third edge. The guide mechanism 14 is configured so that the distance a between the first straight edge and the third straight edge can be varied while maintaining the parallelism between the first and third edges.

[0023] The Fig.Figures 4 to 7 each show a top view of an embodiment of the device according to the invention, comprising a template body 2 and a connecting body 6. The figures serve to illustrate the functionality of the device for drawing various stars, each indicated by a dashed line. First, the outer vertices of the star are marked on a workpiece using the template body 2 and a suitable marking instrument. As can be seen in the figures, the first straight edge 8 of the connecting body is then placed at a first vertex, and simultaneously, the first straight edge 8 or the second straight edge 10 is placed at a further vertex that is not adjacent to the first vertex. Then, a line of suitable length is drawn on the workpiece using a suitable marking instrument.If this process is carried out for each created vertex, an intersection point is obtained between any two vertices where two lines have been drawn in this way. These intersection points each define an inner vertex of the star.
