The present invention relates to a tailor cutting assembly, and more particularly to a tailor cutting assembly with anti-slip function and tailor ruler thereof.
As is well known, to easily identify and set a distance when cutting cloth, a conventional tailor ruler provides the functions of guiding to draw an angled line, measuring angles, setting distance and equally dividing parts. In addition, some tailor ruler manufacturers provide an anti-slip structure on a back of the tailor ruler to prevent the abut tailor and cloth from an offset condition because the tailor ruler is directly pressed on the cloth during cutting. The anti-slip structure is provided along the edge of the tailor ruler. The vertical lines and the horizontal lines on the tailor ruler forms a checkerboard. Consequently, the conventional anti-slip structure needs a lot of anti-slip material, but provides poor anti-slip function. As a result, the anti-slip is wasted and the cost of the conventional tailor ruler is imperceptibly raised.
In addition, the conventional anti-slip material usually is UV (Ultraviolet Rays) glue. As the name suggests, the UV glue needs to be illuminated by UV ray when being hardened such that the costs of material and manufacturing is high. The hardened UV includes the advantages of wear resistance, solvent resistance and impact resilience and has a high strength, however, the hardened UV glue provides a poor anti-slip function to the conventional tailor ruler.
The present invention has arisen to mitigate and/or obviate the disadvantages of the conventional tailor ruler.
The main objective of the present invention is to provide an improved tailor cutting assembly and tailor ruler thereof that use sharp particles to promoted friction force thereof.
To achieve the objective, the tailor ruler in accordance with the present invention comprises a transparent substrate having a front surface and a back surface. The transparent substrate includes a series of scales peripherally formed on the front surface thereof, a series of parallel lines formed on the front surface thereof and a series of longitudinal lines formed on the front surface thereof, wherein the series of parallel lines and the series of longitudinal lines respectively perpendicularly correspond to one another. Each of the parallel lines and the longitudinal lines respectively has a series of reference lines formed thereof. Each intersection of the parallel lines and the longitudinal lines is formed with an identifying point. An anti-slip layer is disposed on the back surface of the transparent substrate, wherein the anti-slip layer is disposed along an edge of the transparent substrate. The material of the anti-slip layer is selected from a group consisted of thermoplastic polyurethane (TPU), rubber printing ink and silicone. The anti-slip layer contains countless sharp particles, wherein the sharp particles are partially exposed relative to a surface of the anti-slip layer for promoting a fraction force of the anti-slip layer and enhancing an anti-slip effect of the tailor ruler.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.
Referring to the drawings and initially to
In the preferred embodiment of the present invention, the sharp particles 51 has a property of high hardness and is selected from a group consisted of silicon-carbide and glass sand. With reference to
The color of the reference line 14 is different from that of the parallel line 12 and the longitudinal line 13 for featuring the comparison between the reference line 14 and the parallel/longitudinal line 12/13. The transparent substrate 10 has a seam allowance reference area 30 formed on the front surface thereof, wherein the seam allowance reference area 30 contains a full allowance reference line 31 and a semi allowance reference line 32.
The transparent substrate 10 further includes multiple angled lines 40 formed on the front surface thereof respectively along the angles of 30 degrees, 45 degrees and 60 degrees for the operator easily to mark the cutting line or draw an angled line on the cloth 80.
Each parallel line 12 and each longitudinal line 13 respectively has a series of separation scales 15 formed thereon, wherein each intersection of the separation scale 15 and the parallel lines 12/the longitudinal lines 13 is formed with a set point 151 for operator to easily divide a segment and measure a segment.
With reference to
Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
