Indicating fastener loading

An amplified indication of the elongation of a fastener is provided for determining instantaneous loading conditions of a fastener. A load indicator is couplable to a fastener for instantaneous load measurement and includes a housing defining a fastener interface configured to removably couple the housing to a fastener. A moveable datum probe extends from the housing in contact with a datum rod anchored within an internal bore of the fastener. A first lever is pivotally mounted within the housing and is moveable in response to displacement of the datum probe. A load display indicates a degree of loading of a fastener as a function of displacement of the datum probe. A second lever can be used to further amplify the reading from the displacement of the datum probe. An inclined visual scale and a multi-faceted lens allows for viewing of loading values from multiple directions or angles.

Gestures and tools for creating and editing solid models

A modeling tool is activated in a 3D modeling application executing on a multi-touch device. A visual representation of a grid system tool is displayed in an active modeling plane and has three separate regions that determine the type of operation to be performed. An existing 3D form is displayed on the tool. A starting touch event of a gesture is received over the existing 3D form within one of the regions. As the gesture is received in the computer, the 3D form may be dynamically extended by adding 3D geometry to the 3D form (thereby adding faces to the 3D form). Alternatively, the 3D form may be scaled (i.e., if the starting touch event occurs over a visual scale grip. Alternatively, if the gesture consists of two taps, a bridge may be created joining the two tapped locations.

Method and apparatus for indicating a load

ActiveUS20080047353A1Degree of reductionReduced range of movementMeasurement of torque/twisting force while tighteningIndication apparatusVisual perceptionFastener
The present invention provides an innovative method and apparatus for determining continuous, visual clamp load status during tightening and throughout the life of a fastener. The present invention provides a pair of levers suitably configured and positioned within a fastener to provide an amplified indication of the deformation of the fastener as a load is applied to the fastener. In accordance with one aspect of the invention, a first lever is connected at an internal pivot point of a cartridge with the lower end of the first lever resting upon an abutment within the fastener, while the upper end displaces the lower end of a second lever such that movement of the upper end of the second lever is amplified with respect to movement of the lower end of the first lever. As the fastener is tightened, the fastener will elongate causing the abutment to move away from the lower end of the first lever. As the abutment moves, the first lever pivots or rotates causing the upper end or indicator of the second lever to move relative to a visual scale that is calibrated to indicate clamping force. The cartridge carrying the two levers is inserted into the fastener with the lower end of the first lever being displaced by the abutment a distance corresponding to a preselected elongation of the fastener, placing the indicator end of the second lever at the lower vales of the indicator scale. As the fastener is tightened, elongation of the fastener causes displacement of the abutment and a movement of the indicator up the indicator scale. If the fastener loses tension, the fastener will contract and the abutment will again displace the lower end of the first lever, rotating the indicator end of the second lever toward the lower values of the indicator scale. Assembly and calibration of the device requires the simple, inexpensive process of advancing the cartridge within a central bore in the fastener.
