This invention concerns a drawing device intended for, but not limited to, children over the age of 7 and adults which enables them to produce precise designs and in particular point-symmetrical patterns, known as Mandalas on standardized sized drawing material, particularly paper. This invention makes it possible to very easily produce simple as well as complicated symmetrical patterns and designs by combining, repeating and/or mirroring the shapes provided by the stencil.

BACKGROUND ART

Several drawing instruments have previously been developed in attempts to enable children to easily produce symmetrical designs.

EP1108562 provides for a drawing instrument which secures the drawing material with a slot in at least one corner region of the support surface. The template is round and rotatable about its central point while being guided by a template guide. It further provides for a central guide element designed as an axle stub which projects from the support surface with the template then being provided with a central opening with which it can be placed on the axle stub.

FR2893534 provides for a drawing instrument which consists of a circular plate with a bearing surface for the drawing material and an accessory frame which is placed upon the bearing surface providing for an inner periphery. The frame has a notching that operates with an accessory in notched discs so it is arranged in the inner periphery.

US4391045 provides for a drawing instrument or apparatus which consists of a frame having a circular opening and a multi-lobed cam- shaped recess and a disc with stencil shaped openings in its surface that has a multi-lobed cam-shaped external surface or edge. The disc is placed within the recess and by placing a writing instrument within the stencil opening and tracing along its outline the disc will move and a design is created.

This invention is remarkable in its simplicity and the interaction between its inner and outer frame and the stencil(s) which together provide for very precise yet complicated patterns and designs to be easily created. Previous solutions do not provide for a completely securing of the drawing paper and the stencils will still be able to shift a little unlike this invention. This invention protects the drawing material not only from being shifted but also from being creased or wrinkled during the drawing process. Furthermore, the stencil and the drawing material can be removed from this drawing device and assembled again while still maintaining the same center point. The smooth, even and thin surface of the drawing device when assembled makes it very easy and comfortable for the user to rest his hands upon it. This combined with the drawing device allowing for the use of standardized pieces of paper makes this invention very user friendly for all ages.

DESCRIPTION OF THE INVENTION

Hereinafter, one embodiment of the present invention in the case where the present invention is applied will be described with reference to FIG.l. In the following detailed description, only certain exemplary embodiment of the present invention is shown and described, by way of illustration. As those skilled in the art would recognize, the invention may be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein.

FIG.l is a diagram showing an exemplary embodiment according to the present invention.

Referring to FIG.l, the drawing device for creating Mandala according to the exemplary embodiment of the present invention includes a base plate (1), a support surface (2), an outer frame (3), an inner frame (5) and one or more stencils (9). The base plate (1), the support surface (2) and the outer frame (3) are a single molded unit with the support surface (2) being slightly recessed (4) in relation to the outer frame (3) which then borders the inner frame (5). The inner frame (5) has the exact measurements of the support surface (2) and it contains one or more voids (6) within. The inner frame (5) is positioned inside the outer frame (3) and onto the drawing material lying on the support surface (2). The stencil (9) is non-circular and exhibits at least three edges. The stencil (9) is shaped to fit precisely into the matching void of the inner frame (5) and is positioned within this void (6) and onto the drawing material lying on the support surface (2). The outer frame (3) contains one or more small integrated cut out sections (7) on one or more of its internal edges to provide easy access for a finger to remove the inner frame (5). Similarly, the inner frame (5) has one or more small integrated cut out sections (8) on one or more of its internal edges to provide easy access for a finger to grab/remove the stencil (9). When the inner frame (5) and the stencil (9) are positioned on the drawing material lying on the support surface (2), preferably they are amounted to the same thickness as the outer frame (3) as they are the same thickness as the recess (4) which exist between the outer frame (3) and the support surface (2).

The support surface (2) is custom-shaped to fit standardized sized drawing material, particularly pieces of paper, and the single molded unit is provided with grip material underneath the base plate (1).

The drawing device according to the present invention illustrated in FIG.l for creating Mandala provides for the drawing material and the stencil(s) (9) to be securely fastened, yet easily removed, and prevents both the drawing material and the stencil(s) (9) from any moving/sliding due to the interaction between the single molded unit, the inner frame (5) and one or more stencils (9). The outer frame (3) secures the inner frame (5) due to the inner frame (5) being the exact measurements of the support surface (2) which is slightly recessed in relation to the outer frame (3) and the inner frame (5) secures both the drawing material and the stencil(s) with the stencil(s) (9) being the exact size and shape of the void(s) (6) within the inner frame. This combined with both the inner frame (5) and the stencil(s) (9) being applied directly to the drawing material lying on the support surface (2) also protects the drawing material from being creased, wrinkled or torn when designing the patterns and/or being removed from the drawing device. The stencil(s) (9) being non circular makes it possible to ensure that they do not move or shift at all when being used. Due to the small integrated cut outs (7) and (8) on the edges of both the outer frame (3) and the inner frame (5), allowing for a finger to easily grab either the inner frame (5) or the stencil (9), it is very simple for even a child to combine, separate and re- combine the elements described. The stencil(s) (9) can now easily be lifted up and rotated or mirrored repeatedly while still maintaining its exact center point. When the inner frame (5) is positioned within the outer frame (3) on the support surface (2) and the stencil (9) is positioned within the void (6) of the inner frame (5) on the support surface (2), preferably they are amounted to the exact thickness of the outer frame (3) thus making it very easy and comfortable for the user to rest the hand which holds the pen on the drawing device. This combined with the base plate (1) having grip the drawing material underneath, the drawing device is prevented from slipping without the user having to secure it either by hand or other means. More specifically, the present invention is not limited to the above embodiment, and can be modified variously within the range shown in the claims. Embodiments obtained by combining technical means appropriately modified within the range shown in the claims also are included in the technical range of the present invention.
