Description

Technical Field

[0001] This utility model relates to the field of women's clothing pattern making technology, specifically a women's clothing pattern making ruler. Background Technology

[0002] In the field of garment pattern making, a women's clothing drafting ruler is a tool specifically designed for drawing women's clothing patterns. Because women's clothing designs typically involve numerous curves, such as armholes, necklines, and hems, which require precise and smooth curves, ordinary rulers alone are insufficient to draw these complex lines. Therefore, a specialized drafting ruler capable of providing various standard curves and arcs is needed to help pattern makers quickly and accurately create women's clothing patterns.

[0003] When drawing complex curves, existing drafting rulers often require the use of multiple different tools. When the direction needs to be adjusted during the drawing process, the pen tip must be completely lifted and then repositioned, which can easily cause breakage or misalignment at the line connection. At the same time, the types of arcs of traditional rulers are relatively limited, making it difficult to meet the rich and diverse curve requirements in women's clothing design, which brings many inconveniences to the drafting work. Utility Model Content

[0004] The purpose of this utility model is to provide a women's clothing drafting ruler to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A women's clothing drafting ruler includes a straight ruler. One side of the straight ruler is straight, and the other side of the straight ruler has several first arc grooves with different curvatures. One side of the straight ruler has a semicircular ruler. A semicircular slit is formed at the intersection of the semicircular ruler and the straight ruler. A curved slit is formed on the straight ruler adjacent to the semicircular slit. A right-angle slit is formed on the straight ruler adjacent to the curved slit. Two arc-shaped slits with different curvatures are formed on the straight ruler adjacent to the right-angle slit. A beveled slit is formed on the straight ruler adjacent to the arc-shaped slit.

[0006] Preferably, an arc-shaped ruler is provided on the other side of the width of the ruler, and convex rulers are provided on both sides of the length of the arc-shaped ruler, with a semi-circular groove between the convex rulers.

[0007] Preferably, one side of the width of one of the convex rulers is connected to one of the first arc grooves of the straight ruler in an arc shape, and the other side of the width of the convex ruler is connected to the outer arc of the arc ruler at an outer arc angle.

[0008] Preferably, a plurality of second arc grooves are provided at the connection between the outer arc of the convex ruler and the arc ruler, and the arc of the second arc groove is greater than the arc of the first arc groove.

[0009] Preferably, the width of the other convex ruler is recessed inward and connects to the straight side of the ruler at an inner arc angle, and the other side of the width of the convex ruler at this location connects to the inner arc of the curved ruler at an outer arc angle.

[0010] Preferably, the connection between the inner arc of the convex ruler and the arc ruler is set as an outer rounded corner, a full circular groove is opened on the arc ruler adjacent to the semi-circular groove, and a hanging hole is opened at the end of the arc ruler.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This women's clothing drafting ruler, through the combined use of semi-circular seams, curved seams, right-angle seams, arc seams, and oblique seams, allows for adjustment of the ruler angle while keeping the pen tip in constant contact with the paper during the drawing process. This effectively solves the problem of discontinuous line connections caused by the need to lift the pen tip for repositioning during traditional drawing, ensuring natural and smooth line transitions.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4 As shown, this utility model provides a technical solution: A women's clothing drafting ruler includes a straight ruler 101. One side of the straight ruler 101 is straight, and the other side of the straight ruler 101 has several first arc grooves 102 with different curvatures. One side of the width of the straight ruler 101 has a semicircular ruler 103. A semicircular slit 104 is formed at the intersection of the semicircular ruler 103 and the straight ruler 101. A curved slit 105 is formed on the straight ruler 101 adjacent to the semicircular slit 104. A right-angle slit 106 is formed on the straight ruler 101 adjacent to the curved slit 105. Two arc-shaped slits 107 with different curvatures are formed on the straight ruler 101 adjacent to the right-angle slit 106. An oblique slit 108 is formed on the straight ruler 101 adjacent to the arc-shaped slits 107.

[0017] The above scheme allows for the drawing of basic straight lines and standard right angles using the flat side of the ruler. Several first arc grooves with different curvatures on the other side of the ruler provide various preset arc trajectories to meet the curve requirements of different parts in women's clothing design. A semi-circular ruler on the wide side of the ruler can be used for angle measurement and drawing semi-circular outlines. A semi-circular slit at the intersection of the semi-circular ruler and the ruler accurately guides the pen tip to complete semi-circular drawings. A curved slit on the ruler adjacent to the semi-circular slit provides a guide path for drawing free curves. A right-angle slit on the ruler adjacent to the curved slit facilitates the rapid drawing of right-angle turning structures. Two arc-shaped slits with different curvatures on the ruler adjacent to the right-angle slit provide two commonly used curve drawing templates. An oblique slit on the ruler adjacent to the arc-shaped slit can be used to draw straight lines with specific tilt angles.

[0018] In this embodiment, preferably, an arc-shaped ruler 109 is provided on the other side of the width of the ruler 101, and a convex ruler 110 is provided on both sides of the length of the arc-shaped ruler 109, and a semi-circular groove 111 is provided between the convex rulers 110.

[0019] The above scheme expands the curve drawing function range by using an arc-shaped ruler on the other side of the ruler width, further expands the curve drawing function by using convex rulers on both sides of the arc-shaped ruler length, and provides an independent semi-circular drawing unit by using a semi-circular groove between the arc-shaped ruler and the convex ruler.

[0020] In this embodiment, preferably, one side of the width of the convex ruler 110 is connected to one of the first arc grooves 102 of the straight ruler 101 in an arc shape, and the other side of the width of the convex ruler 110 is connected to the outer arc line of the arc ruler 109 at an outer arc angle.

[0021] The above scheme achieves a natural transition between the straight ruler area and the curved ruler area by connecting one side of the convex ruler width with one of the first arc grooves of the straight ruler in an arc shape, and forms a smooth outward arc connection point by connecting the other side of the convex ruler width with the outer arc of the curved ruler at an outward arc angle.

[0022] In this embodiment, preferably, a plurality of second arc grooves 112 are respectively provided at the connection between the outer arc of the convex ruler 110 and the arc ruler 109, and the arc of the second arc groove 112 is greater than the arc of the first arc groove 102.

[0023] The above scheme provides options for drawing arcs with larger radii of curvature by creating several second arc grooves at the connection between the outer arc of the convex ruler and the arc ruler, thus enriching the diversity of curve design.

[0024] In this embodiment, preferably, the width side of the other convex ruler 110 is recessed inward and connected to the straight side of the ruler 101 at an inner arc angle, and the other side of the width of the convex ruler 110 at this location is connected to the inner arc line of the arc ruler 109 at an outer arc angle.

[0025] The above scheme creates the conditions for drawing an inward-curving arc by connecting the concave side of the convex ruler to the straight side of the ruler at an inner arc angle. The turning point of the outward-convex arc is constructed by connecting the other side of the convex ruler to the inner arc of the curved ruler at an outer arc angle.

[0026] In this embodiment, preferably, the inner arc of the convex ruler 110 and the arc ruler 109 is provided with an outer rounded corner 113, a full circular groove 114 is provided on the arc ruler 109 adjacent to the semi-circular groove 111, and a hanging hole 115 is provided at the end of the arc ruler 109.

[0027] The above solution achieves the function of drawing smooth corners by setting the inner arc of the convex ruler and the arc ruler as an outer rounded corner. The full circle groove opened on the arc ruler adjacent to the semi-circular groove provides a complete circle drawing template. The hanging hole opened at the end of the arc ruler facilitates storage after use.

[0028] In this embodiment of the women's clothing drafting ruler, the user first uses the straight side of the ruler 101 to draw basic straight lines and right angles. When it is necessary to draw curved lines, the pen tip can be moved into several first arc grooves 102 on the other side of the ruler 101. These first arc grooves 102 have different curvatures, allowing the user to select a specific curvature curve trajectory for drawing according to design requirements.

[0029] At the intersection of the semicircular ruler 103 and the straight ruler 101, a semicircular slit 104 is provided. This slit is specifically designed to guide the pen tip to draw standard semicircular arcs. The adjacent curved slit 105, right-angle slit 106, arc slit 107, and beveled slit 108 are all designed as narrow slits that can only accommodate the pen tip. During dynamic drawing, if a line needs to be drawn along these slits and then changed direction, the user does not need to move the pen tip away from the slit. Simply keep the pen tip in place within the slit, then push the entire ruler by hand to change the angle of the slit relative to the paper. The pen tip can then continue to slide along the slit in the new direction. This mechanism effectively solves the problem of discontinuous line connections caused by lifting the pen tip midway and repositioning it in traditional methods, ensuring smoothness and accuracy when lines turn or continue.

[0030] On the other side of the width of the ruler 101, there is an arc-shaped ruler 109, whose convex ruler 110 structures on both sides enhance the stability of the ruler body when drawing complex patterns. One side of the convex ruler 110 smoothly connects to a first arc groove 102 of the ruler 101 in an arc shape, while the other side of the convex ruler 110 connects to the outer arc of the arc-shaped ruler 109 at an outer arc angle. Several second arc grooves 112 formed at this connection point have a curvature that is generally greater than that of the first arc groove 102, providing users with the option to draw curves with larger amplitudes. The outer arc and inner arc of the arc-shaped ruler 109 itself are two ready-made drawing references with different curvatures, which can be used to quickly outline the contours of the corresponding arcs. The semi-circular groove 111 and the full-circular groove 114 on the arc-shaped ruler 109 are used to draw semi-circular and full-circular patterns, respectively. On the other side, the width of the convex ruler 110 is connected to the straight side of the ruler 101 by an inward concave design, forming an inner arc angle. The other side of the convex ruler 110 transitions to the inner arc of the curved ruler 109 through an outer rounded corner 113. This outer rounded corner 113 can also be used as a drawing tool to draw specific outer arcs. Finally, the hanging hole 115 at the end of the curved ruler 109 provides a convenient hanging and storage function.

[0031] Throughout the drawing process, users can flexibly switch the pen tip position between ruler 101, curved ruler 109, various curved grooves, gaps, and circular grooves according to the complexity of the design lines. This enables the rapid, coherent, and precise drawing of various geometric shapes, from straight lines, right angles, and curves of different curvatures to semicircles and full circles, on a single ruler, greatly improving the efficiency and quality of women's clothing pattern making.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
