Abstract

Zgłoszenie dotyczy ramy roweru poziomego o zmiennej geometrii składająca się z belki głównej (1) wygiętej w części środkowej względem kierunku jazdy, ku górze - do mocowania siedziska (3), belki poprzecznej (2) do mocowania kół przednich (4) oraz belki wsporczej (5), na której początku względem kierunku jazdy zamontowany jest mechanizm korbowy (6) ponadto na dwóch krańcach belki poprzecznej (2) zamontowana jest kierownica lewa (7) i kierownica prawa (8) oraz na belce głównej (1) w jej przedniej i tylnej części zamontowane są koła zębate (9) i (10) do prowadzenia łańcucha, ponadto do belki głównej (1) w jej części środkowej zamontowany jest poziomo widelec tylny (11) do mocowania koła jezdnego tylnego (12), charakteryzującej się tym, że belka główna (1) jest połączona z widelcem tylnym (11) za pomocą połączenia przegubowego i znajdującego się na jej końcu względem kierunku jazdy oraz do środkowej części widelca tylnego (11) i górnej części belki głównej (1) za pomocą połączenia śrubowego zamocowany jest mechanizm podporowy (14).The application concerns a frame of a recumbent bicycle with variable geometry, consisting of a main beam (1) bent in the middle part relative to the direction of travel, upwards - for mounting the seat (3), a cross beam (2) for mounting the front wheels (4) and a support beam (5), at the beginning of which a crank mechanism (6) is mounted relative to the direction of travel, furthermore, at the two ends of the cross beam (2) a left handlebar (7) and a right handlebar (8) are mounted and on the main beam (1) in its front and rear parts, gear wheels (9) and (10) are mounted for guiding the chain, furthermore, to the main beam (1) in its middle part a rear fork (11) is mounted horizontally for mounting the rear wheel (12), characterized in that the main beam (1) is connected to the rear fork (11) by means of an articulated connection and located at its end relative to the direction of travel and to the middle part of the rear fork (11) and the upper part of the main beam (1) the support mechanism (14) is attached by means of a screw connection.
