Construction playset intended for building complex mechanic 3-D models

The utility model belongs to a type of play and souvenir construction kits (meccanos) designed to form models by connection (coupling) and assembly (mounting) sheet material and connection elements. Such models can be 3-D constructions for children.

Popular similar "Marco Construction Playset" comprises a set of construction and connection elements. For it, the construction elements are made in the form of a beam cross- shaped in its cross-section, and each connection element of the kit has cross shape, at the same time rod-like elements as axial independent elements are made in the form of one-stage and two-stage rods. (Declarative patent of Ukraine on invention N° 65775 A, IPC A63H 33/04, publ. 15.04.2004, Bui. N°4) [1]. The said construction playset is designed to simplify production of certain elements included in the construction kit and to reduce their production cost, however design features of the said utility model assemblies limit width, length and volume of the constructed model by dimensions of connection elements and allow only a limited number of simple static and movable models.

Popular «Dynamic Model Toy Produced and Assembled from Sheet Materials The dynamic toy model is produced and assembled on a frame basis. At least one modeling component is to be mounted on the frame; the connection elements and driving gear elements are disposed between each component driving gear and modeling components. The framework comprises at least a frame, parts of the frame and connecting pieces joined by pins or other connecting pieces fastened in the form of the frame and connection elements coupled due to clutching pins or other connection elements in the form of the frame. The mechanism of driving gear is a connecting-rod type gear (National application number CN20082127631U 20080717), application JN° PCT CN201239540 (Y) dated 20 May 2009, IPC A63H13/00; A63H31/00; A63H7/00 [3].

The said construction kit allows building only simple dynamic constructions with complicated procedure of connecting elements and using con-rod mechanism. Design features of the said utility model assemblies limit width, length and volume of the constructed model by dimensions of connection elements and allow only a limited number of simple movable models. The closest similar model to the said utility model is a utility model "Assembly of Separate Mechanical Model Movable Elements Capable of Rotating on One Axis". The assembly of separate mechanical movable elements of the model capable of rotating on one axis comprises the axis and components of separate movable elements connected between them. The assembly comprises the first and the second group of components, wherein the first group of components comprises not less than two separate elements, and each of the said separate elements of the first group has one central hole for the axis to be inserted therein, at the same time each of not less than two separate elements of the first group has not less than two rectangular coupling holes symmetrically disposed around the central hole on each of the separate components of the first group, at the same time the second group of components contains not less than two outer elements produced as pair-wise symmetric, and each of the said separate elements has protrusions along the edges and each of the said separate elements of the second group also has not less than one protrusion in the central part, at the same time the first and the second group of components are connected between them by advance mounting of separate elements of the second group, at the same time forming central axial clearance between the ends of protrusions of separate elements of the second group, further insertion of protrusions disposed on lower edges of certain elements of the second group into not less than two rectangular coupling holes of one of the separate elements of the first group and further insertion of other protrusions disposed on the edges of separate elements of the second group into not less than two rectangular coupling holes of the other separate element of the first group, and further insertion of the axis into the central axial hole of the other separate element of the first group, into the central axial clearance formed by the ends of protrusions of the separate components the second group and into the central hole of the other separate component of the first group (Patent on utility model N295685 U, IPC A63H 33/00, public. 25.12.2014, Bui. JN¾24) [3]. The said similar model has complex procedure of a movable construction assembly building since it requires advance mounting of the central construction components forming axial clearance by end parts thereof for further connection with other elements of the construction by fixing details. The width, length and volume of this construction are also limited by dimensions of connection elements and by the length of the axis to be inserted into the central hole.

The main objective of the utility model is to design a new ecologically friendly construction kit of complex mechanic 3-D models comprising static and movable parts with using no adhesive materials, and not limited on their length, width and volume by the size of fixing (connection) elements due to new features, namely, by replacing construction forming elements, introducing new elements, in particular, building elements, allowing their connection with fixing elements, at the same time, a model is formed without any additional coupling elements and any adhesive substances.

The task set is resolved by producing the construction playset comprising various kinds of construction and connection elements differing in their structure and shape from the kits we know. The innovation of the kit is that the said construction playset comprises forming, building and fixing elements that are capable of consecutive connection between them, for that the first ones have equal thickness and required shape and at least two of the forming elements have at least one rectangular and/or round hole; and/or at least one outer slot and/or slit, and that are disposed layer-wise with the possibility to be connected between them by at least one fixing element, forming together a static or moving construction, for that the fixing element has a needle-like shape and sharpened ends, and round-shaped cross- cutting with the diameter equal to the diameter of at least one round hole on the forming elements, and at least two building elements have rectangular-shaped ends, being equal to the size of at least one rectangular hole on the forming elements, and are fit to be inserted perpendicular into rectangular holes on the forming elements with their further coupling with the latter, and for that their thickness is equal to the width of slots and/or slits on the forming elements.

The task of the utility model is resolved based on the proposed simple reliable consecutive connection of forming elements between them and with the building elements by means of needle-like shaped fixing elements with sharpened ends and with no adhesive materials. As a result, a new reliable connection system of the constructive elements in the construction kit has been created allowing gradual volume building-up in a model of any configuration, length and width. At the same time fixing elements used for rigid fixing of construction kit elements and providing model building-up also function as axial details, if required by the structural concept.

In other words, as a result of this complex approach, the goal of developing a new ecologically friendly construction playset of complex mechanic 3-D models comprising static and movable parts and using no adhesive materials, and not limited on their length, width and volume by the size of fixing (connection) elements has been reached.
