1006 results about "Tape measure" patented technology

A tape measure or measuring tape is a flexible ruler and used to measure distance. It consists of a ribbon of cloth, plastic, fibre glass, or metal strip with linear-measurement markings. It is a common measuring tool. Its design allows for a measure of great length to be easily carried in pocket or toolkit and permits one to measure around curves or corners. Today it is ubiquitous, even appearing in miniature form as a keychain fob, or novelty item. Surveyors use tape measures in lengths of over 100 m.

Tape measure attachment

An apparatus can be conveniently and temporarily attached to a tape measure to aid in measuring a workpiece. The apparatus has a means of engaging a workpiece at one end of a length to be measured, and has a means of removably attaching to the tape measure. The attachment mechanism consists of a rigid, substantially flat member which is designed to rest under the tape, with two tabs protruding upwards from said rigid member. Each tab has at least one kerf formed in the side of that tab which is adjacent to the tape when the rigid member rests under the tape, so that the curving edges of the tape fit into those kerfs, holding the apparatus in place. In this manner, the apparatus is conveniently attachable to and removable from the tape. Furthermore, while the apparatus is attached to the tape, the apparatus adds stability to the tape, by reinforcing the position of the curving edges of the tape. Also, the apparatus can be conveniently slid along the tape to whatever position is appropriate for engaging a workpiece to be measured. The engagement mechanism of the apparatus consists of a rigid, substantially flat member which is attached to the attachment mechanism at a substantially ninety degree angle, so that the rigid engagement member is substantially perpendicular to the tape. One surface of the engagement member is designed to rest against and engage a workpiece to be measured, in a manner which does not harm or mar the workpiece. The surface engaging the workpiece can be tacky, or can have a protrusion designed to insert into a hollow workpiece, such as a pipe.
