Abstract

Przedmiotem zgłoszenia jest model efektu domino, przeznaczony do przeprowadzania doświadczeń o charakterze edukacyjnym, zwłaszcza w obiektach otwartej edukacji, takich jak eksperymentaria i eksploratoria oraz podczas wystaw i festiwali naukowych. Model efektu domino zawiera tablicę w kształcie prostokątnej płyty skierowanej pionowo i połączonej za pomocą wkrętów wzdłuż dolnego boku z podstawą, też w kształcie prostokątnej płyty, ale skierowanej poziomo. Poniżej górnej krawędzi w tablicy jest wykonany pierwszy układ złożony z co najmniej dziewięciu przelotowych otworów rozmieszczonych w równych odstępach od siebie w punktach tworzących wierzchołki kwadratowej siatki i w jeden z tych otworów jest wciśnięty koniec osi (4), która jest nieruchoma i skierowana poziomo. Wystająca z tablicy (1) część osi (4) ma od góry płaskie ścięcie (5) i na tę ściętą część osi (4) jest nałożona piasta (6) mająca otwór (7) w kształcie owalnym. Jedna ze środkowych części łuku o większym promieniu tego owalnego otworu (7) przechodzi w płaski fragment (8) powierzchni o takiej samej szerokości, jak szerokość płaskiego ścięcia (5) i płaski fragment (8) jest oparty na tym płaskim ścięciu (5). Piasta (6) stanowi jedną całość z ramieniem w kształcie pręta skierowanego pionowo i mającego przekrój poprzeczny kołowy. Koniec ramienia jest połączony z kostką w kształcie prostopadłościanu. W osi, (4) po obu stronach piasty, (6) są wykonane przelotowe otwory, w które są wciśnięte kołki (11).The subject of the application is a domino effect model intended for conducting educational experiments, particularly in open education facilities such as experimental and exploratory facilities, as well as during exhibitions and science festivals. The domino effect model comprises a board in the shape of a rectangular plate oriented vertically and connected by screws along the bottom side to a base, also shaped as a rectangular plate, but oriented horizontally. Below the top edge of the board, a first arrangement of at least nine through holes is made, spaced equidistantly apart at points forming the vertices of a square grid. One of these holes receives the end of an axle (4), which is stationary and oriented horizontally. The portion of the axle (4) protruding from the board (1) has a flat cutout (5) at the top, and a hub (6) with an oval opening (7) is placed on this cutout portion of the axle (4). One of the central arc portions with the larger radius of this oval hole (7) merges into a flat surface fragment (8) of the same width as the flat chamfer (5), and the flat fragment (8) rests on this flat chamfer (5). The hub (6) forms a single unit with a vertically oriented rod-shaped arm with a circular cross-section. The end of the arm is connected to a cuboid-shaped block. Through holes are made in the axis (4) on both sides of the hub (6), into which pins (11) are pressed.
