Abstract
Przedmiotem zgłoszenia jest przyrząd pomiarowy o klasycznej konstrukcji skrzynkowej i kształcie podłużnym, wykorzystujący siłę grawitacji ziemskiej do precyzyjnego wyznaczania poziomości płaszczyzn i ustawienia kątów nachylenia, z wbudowaną co najmniej jedną rurką wypełnioną cieczą, na powierzchni której naniesiona jest podziałka. Cechą charakterystyczną wzoru jest to, że jego korpus (1) stanowi profil o długości co najmniej 200 cm, w górnej części lekko łukowaty, mający dwa otwory (2a i 2b), z których każdy otwór usytuowany jest w pobliżu końców przyrządu, przy czym oba otwory (2a i 2b) mają kształt mocno wydłużonych prostokątów, dopasowujących się kształtem do kształtu umiejscowionych wewnątrz korpusu (1) dwóch pionowych rurek (3a i 3b) wykonanych z dowolnego przezroczystego materiału, które są połączone ze sobą giętkim wężykiem w pełen obieg zamknięty i działają na zasadzie naczyń połączonych, które wypełnione są dowolną roboczą cieczą (6), korzystnie nie gęstniejącą i nie zamarzającą. Korzystnie też korpus (1) przyrządu ma przekrój dwu – teowo - skrzynkowy, co zwiększa jego sztywność. Z kolei na jego obu końcach znajdują się osłony wykonane z tworzywa sztucznego absorbujące wstrząsy.The subject of the application is a measuring device with a classic box structure and an elongated shape, using the force of the earth's gravity to precisely determine the horizontality of planes and setting the angles of inclination, with at least one built-in tube filled with liquid, on the surface of which a scale is applied. The characteristic feature of the design is that its body (1) is a profile at least 200 cm long, slightly arched at the top, with two openings (2a and 2b), each opening near the ends of the device, both the openings (2a and 2b) have the shape of strongly elongated rectangles, matching the shape of two vertical tubes (3a and 3b) located inside the body (1) made of any transparent material, which are connected to each other by a flexible hose in a full closed circuit and operate on the principle of communicating vessels, which are filled with any working liquid (6), preferably non-thickening and non-freezing. Preferably, the body (1) of the device has a double-T-box section, which increases its rigidity. In turn, at both ends there are covers made of shock-absorbing plastic.
