REHABILITATION SENSORY PUZZLE SET, ESPECIALLY FOR CHILDREN WITH PSYCHOMOTOR DISORDERS

Abstract

The set consists of smaller elements which complement one another in shape like jigsaw puzzle pieces in such a way that, being interconnected by circular dovetail type connectors situated on the edges, they fill up a larger area of a circular geometric figure. It consists of a central element (1,1a) and many concentric ring-shaped sectors (2 a, 2b, 2h) which, selected according to the radii (r1, r2) and the central angle (co) are interconnected by dovetails (3) on radially oriented edges, forming at least two ring-shaped fields including the central element (1,1a).

Description

[0005] The preferable embodiment of the set according to the model is the one in which the ring-shaped field adjoining the central element is formed of at least three ring-shaped sectors.

[0006] In another embodiment of the model, the central element is connected on the perimeter by the dovetails with two ring-shaped sectors.

[0007] The set according to the model may, after being assembled, have a form of a matt of one layer of elements with a uniform thickness, smaller than 0.02 of the diameter of the outer surface area of the circle formed of the set elements.

[0008] The set can also be made of elements which, when assembled, form a cylinder body combined of one or several layers of elements with various thicknesses, the layers being laid one on another, ranging from 0.05 to 0.5 of the external diameter of the cylinder of the assembled set.

[0009] The central element of the set may have a height equal to the cylinder height, or, in the multi-layer embodiment, its height is formed by the sum of the thicknesses of the elements of the particular layers.

[0010] In another embodiment of the set according to the model, on the circular edge of the central element and the adjoining ring-shaped sectors there are made dovetail blanks into which a two-tab wedge is inserted.

[0011] The set forming the cylinder body may contain elements of the particular layers in different colours.

[0012] All elements of the set according to the model are made of elastomeric composite material which is safe for health.

[0013] The set according to the model gives a rehabilitated child with psychomotor disorders a simple task to select and interconnect ring-shaped sectors in such a way that they form a circular matt or a cylinder body. At the same time, it allows the person conducting the therapeutic rehabilitation to select a form of the set with a simpler or more complex task as appropriate for the degree of the child's integration ability development delay.

[0014] The rehabilitation set according to the utility model is presented on the drawing in two essential embodiments as a small set with simpler combinative tasks and a large set with the task level being slightly more difficult. At the same time, the sets assembled of the so shapedin the top viewelements may, depending on the thickness, fount a flat matt or a cylinder body. The particular figures of the drawing present: FIG. 1 a top view of the small set, FIG. 2 a top view of the large set, FIG. 3 to FIG. 10the components of the small set cylinder body, and FIG. 11 to FIG. 19the cylinder body components according to the large set.

[0015] The small set, shown on the top view on FIG. 1, consists of the following adjacent elements: the central element 1 with a radius r1, one ring-shaped sector 2a with the central angle =180 and two ring-shaped sectors 2b with the central angle =90 jointly forming the internal ring-shaped field and one ring-shaped sector 2c with the central angle =180 and two ring-shaped sectors 2d with the central angle =90forming the external ring-shaped field with the inner radius r2. The ring-shaped sectors constituting both fields are interconnected by circular dovetails 3 which are formed on the radial edges and tabs 3b of which are introduced into blanks 3a of the adjoining sector. The elements of the small set made with the thickness g1 smaller than 0.02 of the inner diameter D1 of the surface area of the circle assembled of the elements of that set form a flat matt. With the diameter D1=100 cm, thickness g1<2 cm. The elements of the small set in the cylinder body embodiment are shown on FIG. 3 to FIG. 10. The cylinder can be formed by elements of one layer consisting of elements with a thickness of g1=h=from 0.05 to 0.5 of the inner diameter D1 of the cylinder of the assembled setwhich results in the range from 5 to 50 cm with D1=100 cm. The cylinder body can also be formed of many layers with thicknesses g2, g3, g4 and g5 overlaying one another and having the total height h.

[0016] The large set consists of elements, the shape of which is presented in the top view on FIG. 2. It consists of one central element 1a with the diameter 2r1, six ring-shaped sectors 2e,2e,2e,2e,2f,2g with central angles =45 forming the internal ring-shaped field and two ring-shaped sectors 2h with central angles =180forming the external ring-shaped field. Identically as in the small set, the ring-shaped sectors are interconnected with the dovetails 3 and, furthermore, the central element 1a has two dovetail blanks 3a trimmed on the perimeter according to the diameter. One blank is interlocked with the tab 3b protruding from the inner surface of the ring-shaped sector 2f and the two-tab wedge 4 is inserted in the other one, two-tab wedge being also captured in the blank 3a made on the side surface of the ring-shaped sector 2g.

[0017] Depending on the thickness of the elements and the number of layers, the large setsimilarly to the small setmay have a form of a round matt or a cylinder.
