Craft cutting accessory OBJECT OF THE INVENTION

The invention, as expressed in the statement of the present specification, refers to a cutting accessory for handicrafts, which has features, which will be described in detail below, which represent a novelty in the current state of the art.

The object of the present invention lies in an accessory consisting of a tool specifically designed to facilitate precise and comfortable cutting, both unitary and plural, in portions of the polymer clay bars or "baked plasticine", existing in the market to produce multiple types of manual work, being designed for manual use by a user in an easy and safe way, but especially, allowing the portions to always be exactly the desired size.

FIELD OF APPLICATION OF THE INVENTION

The field of application of the present invention is part of the industry sector dedicated to the manufacture of utensils and tools, focusing particularly on the field of cutting tools, and more specifically those intended for private or professional use, that is, Non industrial for crafts and / or crafts.

BACKGROUND OF THE INVENTION

As is known, there is a new type of baked plasticine bar on the market that, unlike traditional modeling clay, consists of a plastic material, namely polymer clay or polymer clay, which hardens when heated.

These bars, for example those marketed under the FIMO® brand by the Staedtler® company, are usually made with different profiles and the combination of several colors and are usually used by cutting small portions of the bar that determine the obtaining of multiple pieces of each design that they present. the bars, for example, flowers, butterflies, or others and that are then attached in necklaces, or stuck on some or other surfaces.

The problem detected is that, when trying to cut said portions of the same thickness to obtain identical pieces, the tools available in the market do not allow to achieve it easily, since, generally, they are cutting blades with which the pieces one by one and must be measured "by eye", the thickness of the cut. On the other hand, the blades or cutting tools currently used for the described cuts of these bars, are sharp tools that do not offer safety guarantees so that they can be used by children, as it would be desirable since said product is an item of crafts.

Consequently, the currently existing cutting tools do not allow multiple cuts or the cutting of identical portions, the objective of the present invention being to develop a specific cutting tool for said work that also allows to offer security for its use by Any user, including children.

On the other hand, and as a reference to the current state of the art, at least on the part of the applicant, it is unknown the existence of any other cutting tool, cutting accessory or similar invention that presents structural and constitutive characteristics similar to those that presents the one that is recommended here, as claimed.

Successfully achieve the previously stated objectives, the characterizing details that make it possible and distinguish it, conveniently set forth in the final claims that accompany this specification.

Specifically, what the invention proposes, as noted above, is a cutting tool designed as an accessory specifically designed to achieve the precise cutting of one or more portions of a polymer clay bar or "baked clay", of the existing ones. in the market to make crafts, avoiding having to make such cuts manually and only unitary and avoiding to choose visually (by eye) the thickness of the pieces or portions of each cut.

For this purpose, the accessory of the invention is configured essentially from a housing to which a mobile cover or pusher is attached that houses one or more blades aligned with the desired separation and arranged so that, by pressing said pusher on the housing, they cut a bar deposited inside it in the corresponding portions and with the thickness chosen depending on the position of separation of the blades and where the portions, once cut, are separated from the blades thanks to a separating grid and fall into a storage drawer provided for that purpose in the case itself.

The accessory of the invention comprises three main parts, the housing, the pusher with the cutting means and the storage.

Thus, the housing, which constitutes the fixed part of the accessory to which the rest of the elements are attached, is composed, in turn, of two parts, an upper one with a hole for the placement of the bar to be cut and on which the pusher slides with the cutting blades, and a lower one on which the upper part is coupled and which has a series of tubular rods in which springs are incorporated and inserted, the upper part of the pusher being pierced, serving as glues and means of return to their initial position. This lower part of the housing also has a central space to accommodate a cutting board, located in coincidence with the hollow of the upper part, on which the bar to be cut is deposited and under which a storage drawer is incorporated .

For its part, the pusher, which engages as a cover on the described housing, is also constituted by two main parts, an upper one that closes it superiorly and on which pressure is made to cut and a lower one with the aforementioned lugs that cross the upper part of the housing and fit in the springs with springs. This lower part of the pusher also has notches in its lower face to accommodate the blades in different positions, depending on the thickness of the portions to be cut. In addition, to ensure the fixation of the blades, the upper part of the pusher has an inside surface that prevents them from moving from their place.

In addition, coupled to this pusher, specifically to the lugs of the lower part of it and below the blades, the incorporation of a separating grid is provided which, once assembled all the parts, acts as a blocking element to avoid that, after pressing the pusher, the cut portions of the bar remain glued to the blades, since said blades pass through the grid and, with the return movement the portions fall, when bumping with the grid detaching from them, on the cutting board and inside the housing drawer when moving said table, and can be picked up when removing said drawer located in the lower part of the housing.

The described cutting accessory for handicrafts, therefore, consists of an innovative structure with characteristics unknown until now for the purpose for which it is intended, reasons that together with its practical utility, provide it with sufficient grounds to obtain the privilege of exclusivity that is requested .

(22), preferably rectangular, are coincident with the set of blades (4) of the pusher (3), which pass through it when pressing said pusher (3), which slides over this upper housing part (2a), cutting the bar.

For its part, the lower housing part (2b) is configured from a flat base (23) on which the upper housing part (2a) fits and which has tubular vertical stems (24) in which in its Inside, springs (8) are incorporated and where they are inserted, passing through the upper housing part (2a) through the aforementioned holes (21), some lugs (31) that the pusher (3) has for this purpose, said gliding stems serving for the sliding of the pusher (3) and said springs (8) of return means to their initial position for the pusher itself (3).

In addition, in this lower housing part (2b), a central space (25) is provided for the incorporation of the storage drawer (7) with the cutting board (6) which is laterally slidable and closes or opens it superiorly. Likewise, the lower housing part (2b) incorporates a side stop (26) which, on the one hand, limits the positioning of the storage drawer (7), which has a pocket (27) in the upper housing part (2a). ) for its extraction which is located on the diametrically opposite side, and, on the other hand, determines the point of support and stop to slide and extract the cutting board (6) by passing through an opening provided the effect on the part of upper housing (2nd).

According to figures 3 and 4, it can be seen how the mobile cover that constitutes the pusher (3) also comprises two parts, an upper cover (3a) that determines the pressure surface (32), and that fits, by means of a perimeter step ( 33) on a lower cover (3b) where the above-mentioned lugs (31) that cross the upper housing part (2a) and fit into the tubular stems (24) with springs (8) appear.

However, the essential part of this lower cover (3b) of the pusher (3) is the notched hole (34) which it presents to fit, as desired, the plurality of blades (4) to cut the bar into the desired portions, whose fixation is combined with a support surface (35) provided on the lower face of the upper cover (3a).

Additionally, as already indicated, the accessory has a separating grid (5) of the cut portions, which, as seen in figures 4 and 5, is formed by a disk (51) with grooves (52) for the passage of the blades (4) and perforations (53) for coupling in the lugs (31) of the lower cover (3b) of the pusher. Thus, when pressing on the housing (2), after cutting the bar housed in the recess (22) on the cutting board (6), the portions fall on this table pushed by the grid (5) when recovering the pusher (3) its initial position by pushing the springs (8).

Once the portions have been cut and deposited on the cutting board (6), it is enough to slide said board out, pulling it through the skirt (61) provided for that purpose, so that said portions fall into the storage drawer (7) that , in turn, can be removed from the opposite side by pulling it through an inlet (71) practiced in its frontal partition.

Finally, it should be noted that, taking into account that generally the bars available in the market usually have a length of 54 mm, preferably, the blades (4) have an approximate thickness of 0.3 mm, and a width of 5 mm. While these measures are at the expense of the manufacturer and its specifications. In any case, while the rest of the elements may be made of any appropriate material, plastic materials being recommended, for example Polystyrene (PS) Polypropylene (PP) or Acrylonitrile butadiene styrene (ABS), both in transparent and opaque plastic, The blades will be made of specialized steel.
