    Abstract: A dumbwaiter is provided. The dumbwaiter includes an elevator mechanically coupled to a left glide and a right glide. The left glide is immediately adjacent to and located between a pair of left guides, and the right glide is immediately adjacent to and located between a pair of right guides. A strap is used for raising and lowering the elevator. As the glides are bound between respective pairs of guides, the elevator is protected from vibration. Thus, the dumbwaiter of the present invention may be suitable for being used in a mobile setting, such as a motor home in transit, for example.
