Abstract : The patent relates to a suction device for gripping an object wherein the device includes a container. The container has a compartment which is capable of withstanding a vacuum relative to ambient pressure, and a plunger slidably and sealably extends through a wall of the container. Elastomeric means are mounted to the exterior of the container about the plunger for forming a chamber. The plunger extends beyond the container so as to be capable of engaging the object and sliding toward the vacuum compartment when the elastomeric means is pushed against the object. The plunger has passageway means for communicating the chamber with the vacuum compartment when the plunger is slid toward the vacuum compartment. With such a device a vacuum is established within the chamber when the elastomeric means is pushed against the object so that the object is gripped for retention, movement, or retrieval purposes.
