  • Patent number: 6595451
    Abstract: Disclosed herein is a tape locking device for tape measures. The tape locking device comprises a locking lever hinged to an upper portion of the wall of the housing in such a way to be rotated frontward and rearward around a hinged joint, and provided with a connecting piece downwardly extending from the locking lever. A cylinder is connected at its first end to a hole formed at the lower portion of the connecting piece, with a coil spring fitted over the cylinder. A wedge-shaped stopper is connected to the second end of the cylinder, and having a desired frictional force. This stopper is elastically biased by the coil spring to be wedged in the gap between the outer circumferential surface of a wound part of the tape around the bobbin and a linear part of the tape led to the slot when releasing the locking lever after drawing a desired length of tape from the slot, so the drawn tape is automatically locked by frictional contact between the stopper surface and the drawn tape surface.

  • Patent number: 5544420
    Abstract: A combination tape measure and light bulb assembly disclosed. A light bulb assembly is affixed to the free end of a semi rigid tape measure. A strip of electrically conductive material is applied to the bottom of the tape measure, with various electrical switching mechanisms described to connect this strip of material to a source of electric current, and thereby light the bulb whenever required by the operator. The light bulb assembly includes a reflector plate for increasing illumination coming from the bulb, and a clear plastic shield for the bulb. The light bulb assembly can also include a magnet to further add to the utility of the combination.
