  • Patent number: 11731291
    Abstract: An extended frame portable vacuum grip device is provided having a rigid unitary support frame with elongated base and peripheral support wall that can define an open chamber at a face of the device for vacuum grip connections. A plurality of corresponding components can be combined to form independent vacuum grip regions within the open chamber extending along the length of the support frame. A plurality of ports can be defined through the base along its length that can each operatively connect with a corresponding pump. A plurality of closed-loop gaskets can each mate with corresponding portions of the base and support wall within the open chamber to act as vacuum seal members and define independent vacuum grip regions. A corresponding support frame for each gasket can help retain the independent arrangement and enhance seal actions of the gasket. The grip device can include structural reinforcements for reducing applied stresses.

  • Patent number: 11433509
    Abstract: A detachable control handle for an extended grip system is provided for attachment with an interface of a portable grip device including a pair of spaced apart connector tabs extending from a rigid frame of the portable grip device and forming a pair of parallel captivation channels. The control handle can include an elongate grip handle and a pair of opposed support arms attached to the grip handle and extending away at angles from each other. The support arms can be more flexible in a perpendicular direction of the portable grip device. A crossarm can extend between the pair of support arms proximate a second end portion for establishing a preset inboard spacing maintaining the pins and support arms in an after-attached arrangement that can interfere with connecting and disconnecting. A method includes a user flexing the engagement members and pins for guiding the attachment.

  • Patent number: 11253978
    Abstract: A self-holding drilling system utilizes a vacuum gripping base and an air extraction pump to apply a holding force toward an object surface while maintaining surface-ward pressure on a drilling apparatus mounted therein. The pump extracts air from two discrete, but coupled volumes: a volume associated with the vacuum gripping base and a volume related to one or more piston tubes mounted transversely to the vacuum gripping element and movably coupled to the drilling apparatus. The surface area of the piston tubes is less than the surface area of the vacuum gripping base, which ensures the holding force is sufficient to prevent the drilling system from lifting from the object surface while also ensuring a driving force on the drilling apparatus is always less than the holding force. Thus, the operation of the drilling apparatus automatically drills into an object surface without requiring manual pressure on the drilling apparatus.

  • Patent number: 11167429
    Abstract: A vacuum gripper sealing element allows a vacuum gripper to suitably conform to irregular surface topology without compromising vacuum conditions. The sealing element utilizes a compressible sealing element which at least partially encapsulates an elastic sealing element. Upon being pressed against an object surface, the compressible sealing element will conform within and around macroscopic peaks, valleys and other irregular physical features. While conforming to macro-scale features, the compressible sealing element applies pressure isotropically upon the encapsulated elastic sealing element, which elastically conforms to micro-scale features while pressed thereagainst. The elastic sealing element has a fluid-filled interior that is surrounded by an elastic outer layer. While under pressure against an irregular surface topology, the fluid-filled interior displaces so as to redistribute internal forces, conforming the elastic outer layer to the micro-scale features of the object surface.
