Measuring device

摘要

A measuring device for providing a portable and easy-to-use electronic measuring device. The measuring device generally includes a housing which includes a locking member, a reel member, a sensing assembly and control unit. A length of string is wound around the reel member, which is secured within the housing in a manner which allows the string to be retracted around the reel member absent outside force. As the string is dispensed through a string opening on the housing, a sensor wheel having a plurality of counting indicia will be rotated underneath one or more sensing members, which act to calculate the distance of string which has been dispensed. This data is communicated to a control unit, which causes the relevant information to be shown on a display on the housing. The locking member may be utilized to stop the string from being dispensed after the requisite length has been dispensed.

主权项

1. A measuring device, comprising:
a housing; a string opening positioned on said housing; a reel member rotatably positioned within said housing, wherein a length of string is wound around said reel member and wherein a first end of said string is fixedly secured to said reel member, wherein a second end of said string extends through said string opening; a sensor wheel rotatably positioned within said housing, wherein said length of string extends partially around said sensor wheel; a plurality of counting indicia positioned on said sensor wheel; at least one sensing member positioned above said sensor wheel for sensing the number of said counting indicia which have passed thereunder; a control unit, wherein said control unit is adapted to receive said number of said counting indicia from said at least one sensing member and calculate a length of dispensed string; memory connected to said control unit; a display connected to and positioned within said housing and connected to said control unit; a power source positioned within said housing and electrically connected to said control unit, said memory and said display so as to power said control unit, said memory and said display; wherein when string is dispensed, the length dispensed string is displayed on said display; wherein when string is dispensed, the length of dispensed string is stored in said memory for future retrieval and use; at least one input mechanism connected to said housing and said control unit; wherein said input mechanism selectively resets a counter of said control unit to calculate a length of dispensed string, and selectively activates and deactivates a counter of said control unit to calculate a length of dispensed string.
