DETAILED DESCRIPTION OF THE INVENTION

[0022] FIG. 1 to FIG. 8 depict a preferred embodiment of the lockable rotary cutting mat according to the invention. It is to be understood, however, that such embodiment examples are for illustrative purpose only, and is not intending to limit the scope of the invention.

[0023] Said lockable rotary cutting mat includes a base plate 10 and a rotary plate 20 assembled on the base plate 10 in a way that it can be pushed to rotate. The central bottom portion of the rotary plate 20 is assembled on the center of the base plate 10 through a rotary connector 30. The bottom portion of the base plate 10 has anti-slip components 40. The rotary plate 20 includes a cutting surface 21 and a periphery 22, wherein the periphery 22 is formed with at least one concave edge portion 23, and at the corresponding position between the base plate 10 and the periphery 22 of the rotary plate 20, a locking component 50 is provided. The locking component 50 includes a moving base 51, a controller 52 and a locking edge portion 53. The controller 52 can be pushed to move forward or backward along the movement guiding axis preset on the moving base 51 in the L1 direction (see FIG. 6). The locking edge portion 53 is connected to and is driven by the controller 52 to have a locked position (see FIG. 8) and a released position (see FIG. 7). When the locking edge portion 53 is located at the locked position, it is aligned to and engaged with the concave edge portion 23, so as to fix the rotary plate 20.

[0024] Referring to FIG. 3, in the embodiment, the center of the base plate 10 is formed with a round hole 11. The periphery of the round hole 11 is formed with a thin ring edge 12 with its thickness less than that of the base plate 10. The rotary connector 30 is an integrally formed thin shell in the shape of a round disk. The rotary connector 30 is formed with a plurality of concentric convex rings 31 with certain intervals. The plurality of convex rings 31 go upward through the round hole 11 and is fixed on the bottom of the rotary plate 20 through adhesive (see FIG. 4). Between the neighboring convex rings 31, concave rings 32 are relatively formed. And the periphery of the rotary connector 30 is formed with a supporting ring face 33. Between the supporting ring face 33 and the rotary plate 20, a clamping slit 34 is defined and formed to clamp the thin ring edge 12 inside. The main efficacy of this embodiment is to achieve the advantage of a thin and light product by using a rotary connector 30 made of a thin shell in the shape of a round disk.

[0025] In particular, the anti-slip component 40 is in the form of printing, with thickness between 0.05 mm and 0.50 mm; the advantage of this embodiment is to provide a thin, smooth and anti-slip product. Specifically, as shown in FIG. 2, when the anti-slip components 40 are configured in the form of multiple concentric rings, they provide vacuum absorption like a suction cup, so that the lockable rotary cutting mat can be placed more stably and securely.

[0026] Referring to FIG. 1 to FIG. 3, in this embodiment, the periphery 22 of the rotary plate 20 is distributed with several concave edge portions 23 with even circular intervals. The two symmetric sides of the base plate 10 are formed with two concave portions 13, each of the concave portions 13 can rotate along with the rotary plate 20 to be aligned to any of the concave edge portions 23. The efficacy of this embodiment is that, when the user's fingers push the rotary plate 20 to rotate (see FIG. 9), there are positioning points to serve as the reference for angle of rotation. In particular, between any two neighboring concave edge portions 23, the optimum peripheral path distance is set as 7.5 degrees, and the cutting surface 21 of the rotary plate 20 is correspondingly provided with a plurality of angle mark lines 24 for visual recognition, so as to help the user recognize the angle of rotational displacement. For example, if the user wants to rotate the rotary plate 20 by 30 degrees, the user can use fingers to tug the concave edge portion 23 for four times to rotate the plate for 30 degrees (7.5 degrees×4 times=30 degrees). This provides a convenient function for the user to achieve desired angle of rotation.

[0027] Referring to FIG. 1 and FIG. 3, in this embodiment, the base plate 10 is further formed with a hang hole 14, and the hang hole 14 is located between the periphery 22 of the rotary plate 20 and the locking component 50. Through the hang hole 14, the product can be hung on a hook configured on an existing wall or cupboard (not shown in the drawing), so as to facilitate storage of the lockable rotary cutting mat to save space occupation.

[0028] Based on the above structural constitution and technical features, in actual applications of the preferred embodiment of the lockable rotary cutting mat according to the invention, as shown in FIG. 9, when the user wants to turn the rotary plate 20 to change its horizontal angle to a desired position, the user can use fingers to push the concave edge portion 23 to easily drive the rotary plate 20 to rotate (as indicated by Arrow L2 in FIG. 9), and when the user decides the rotation angle of the rotary plate 20, the user can use fingers to tug the controller 52 of the locking component 50, and push the locking edge portion 53 to the locked position (as shown in FIG. 8), so that it is aligned to and engaged with the concave edge portion 23 and the rotary plate 20 is stably fixed. On the contrary, to release the rotary plate 20, the user just needs to tug the controller 52 to push the locking edge portion 53 back to its released position (as shown in FIG. 7), and the rotary plate 20 can be rotated again.

[0029] Referring to FIG. 10, in this embodiment, the locking component 50 also includes a mode keeping piece 54 to fix the controller 52, so as to prevent it from moving forward or backward (as shown by the Arrow L3 in the drawing, the fixation is realized by pulling it backward). The main efficacy of this embodiment is to offer better safety by keeping the locking component 50 more stable and secure, so that the user may not be hurt during operations.

[0030] Further, in actual applications, the lockable rotary cutting mat can be used as an assistant mat for making cakes or any of clay, flower or hand crafts. (Note: The product is also applicable for operations with no cutting and only requiring rotation.)
