Abstract

A tape measure includes a spool, a housing defining an opening, where the spool is rotatably coupled to the housing, and a blade including a first end and a second end, where the first end is connected to the spool and the second end is movable through the opening between a retracted position and an extended position. The manually retractable tape measure further includes a cleaning assembly positioned within the housing adjacent the opening such that the cleaning assembly is in contact with the blade to push away debris from the blade as the blade moves between the retracted position and the extended position.

Description

technical field [0001] The present invention relates to tape measures. More specifically, the present invention relates to open roll tape measures with self-cleaning components. Background technique [0002] An open-roll tape measure is a manually retractable type of tape measure. Open-roll tape measures are often used to take longer measurements. For example, many open roll tape measurements include tapes of 100 feet or longer, while conventional tape measures include tapes of no more than about 35 feet. Unlike traditional tape measures, manually retractable tape measures, such as open roll tape measures, typically do not include biasing members to automatically retract the tape. Instead, the user must manually retract the tape. Additionally, these tape measures are often used in environments where dust and debris are present. Dust and debris often collect on the tape measure, which can eventually cause it to jam. Debris can also collect within the tape measure housin...
