发明名称 Door handle extension for recreational vehicles and the like
摘要 A handle extension device for facilitating entry into a recreational vehicle or the like having an elevated door with a substantially flush outwardly pivoting door handle. The door handle extension comprises means for engaging the door handle so as to exert an outward force, and an operating handle operatively connected to and substantially below the engaging means. One embodiment employs a detachable hollow bar with an internal cable connecting the operating handle to a spring-biased lever arm configured to engage the inboard side of the pivoting handle on the vehicle door.

主权项 1. A door handle extension for a paddle handle on a door of a recreational vehicle, comprising: a hollow, rigid bar approximately three feet in length and one inch in width; an internal cable extending longitudinally within said hollow bar at least three fourths the length thereof and constrained to longitudinal motion by a pulley near each end thereof; a paddle-engaging, right-angle, elongate lever vertically pivotally mounted on the upper portion of said bar, said lever having a right-angled free end normally spaced apart from said bar and extending downwardly from the pivot point of said lever at an angle of approximately 45°, said right-angled free end extending approximately one inch from the longitudinal axis of said lever in a direction substantially parallel to the pivot axis of said lever such that said free end engages the inboard side of the paddle on the vehicle door when said door handle extension is installed with the door closed, said lever operatively connected to the upper end of said internal cable such that increased tension on said cable causes said lever to pivot downwardly toward said bar, said lever being spring-biased away from said downwardly pivoted position; an operating handle vertically pivotally mounted on the lower portion of said bar and operatively connected to the lower end of said internal cable such that downward pivoting thereof causes increased tension on said cable; and first and second suction cups mounted on said upper and lower portions of said bar, closely adjacent to said lever and said handle, respectively, whereby said door handle extension can be readily attached to and removed from the vehicle door.
