Device for opening and closing an opening in a wall
First Claim
1. A device in combination with a sliding door, a wall and an opening for opening and closing said opening in said wall, in particular for vehicles, wherein the sliding door is arranged so as to be slidable essentially parallel to the wall by a guide device and drivable by a linear drive which comprises a linearly constructed element, a driving element engaged therewith, an electric motor and a gear mechanism, wherein the linearly constructed element of the linear drive and a slide rail belonging to the guide device are attached to the wall, and the driving element of the linear drive and a slider belonging to the guide device and engaged with the slide rail are attached to the sliding door, wherein the slider is pivotally attached to the sliding door by a joint, said linearly constructed element of said linear drive is constructed as a rack, and said driving element of said linear drive is constructed as a gear rotatably mounted on said slider, said gear mechanism comprises a gear connected to said motor, a gear mounted rotatably on the joint axis between said slider and said sliding door, and said gear rotatably mounted on said slider, said gear mounted on the joint axis meshes with said gear connected to said motor and said gear mounted on said slider, said gear connected to said motor and said gear mounted on said slider being laterally offset from each other with respect to said joint axis to avoid contact with each other.
