Abstract
A portable device for measuring deflection of a surface, comprising an elongate frame having a first end and a second end and a first datum surface, a first removable reference assembly adjacent the first end, a second removable reference adjacent the second end, a deflection gauge attached to the elongate frame between the first removable reference assembly and the second removable reference assembly, and wherein the deflection gauge engages and measures a deflection of the surface relative to the first removable reference assembly and the second removable reference assembly.
Claims22
A portable device for measuring a deflection of a surface, comprising:
- an elongate frame having a first end, a second end, and a first datum surface;
- a first removable reference assembly having a second datum surface, adjacent the first end;
- a second removable reference assembly having a third datum surface, adjacent the second end;
- the elongate frame member variably locked along a direction generally perpendicular to the elongate frame member at a calibrated distance from the surface by the first removable reference assembly and the second removable reference assembly;
- a deflection gauge attached to the elongate frame between the first removable reference assembly and the second removable adjustable reference assembly;
- and
- wherein the deflection gauge engages and measures the deflection of the surface relative to the first removable reference assembly and the second removable reference assembly.
A portable device for measuring a deflection of a surface and operable by a single user, comprising:
- a rigid elongate frame member;
- a first foot adjustably attached to the elongate frame member;
- a second foot adjustably attached to the elongate frame member;
- the elongate frame member adjustably fixed along a direction generally perpendicular to the elongate frame member at a set height from the surface by the first foot and the second foot;
- a measuring tool attached to the elongate frame member;
- a probe associated with the elongate frame member;
- and
- wherein the measuring tool measures the deflection of the surface by the probe touching the surface.
A method for measuring a deflection of a surface, utilizing a portable device for measuring the deflection comprising:
- an elongate frame member having a plurality of weight reduction holes, a first foot adjustably attached to the elongate frame member, a second foot adjustably attached to the elongate frame member, the elongate frame member adjustably fixed at a set distance from the surface by the first foot and the second foot;
- a measuring tool attached to the elongate frame member between the first foot and the second foot;
- the method comprising the step of:
- operating the measuring tool to determine the deflection of the surface.
