Distance measuring apparatus
First Claim
1. A distance measuring apparatus comprising:
- a frame;
a wheel rotatable relative to the frame around a first axis;
the wheel having a peripheral surface that can be rolled against a surface upon which a distance measurement is to be taken;
a counter assembly through which advancement of the distance measuring device can be converted to a distance measurement; and
a scraper assembly comprising a scraping edge that can be selectively fixed in a plurality of different positions relative to the frame so as to be one of (a) adjacent to the wheel, and (b) against the wheel, the scraping edge intercepting foreign matter adhered to the wheel as the wheel is rotated around the first axis to avoid buildup of foreign matter upon the wheel as the distance measuring apparatus is operated.

Abstract
A distance measuring apparatus having a frame and a wheel rotatable relative to the frame around a first axis. The wheel has a peripheral surface that can be rolled against a surface upon which a distance measurement is to be taken. The distance measuring apparatus further has a counter assembly through which advancement of the distance measuring device can be converted to a distance measurement. The scraper assembly has a scraping edge that is one of (a) adjacent to the wheel, and (b) against the wheel. The scraping edge intercepts foreign matter adhered to the wheel as the wheel is rotated around the first axis to avoid buildup of foreign matter upon the wheel as the distance measuring apparatus is operated.

29. A distance measuring apparatus comprising:
-
a frame having a bracket with a surface facing in a first direction;
a wheel rotatable relative to the frame around a first axis;
the wheel having a peripheral surface that can be rolled against a surface upon which a distance measurement is to be taken;
a counter assembly through which advancement of the distance measuring device can be converted to a distance measurement; and
a scraper assembly comprising a scraping edge that is one of (a) adjacent to the wheel, and (b) against the wheel, the scraping edge intercepting foreign matter adhered to the wheel as the wheel is rotated around the first axis to avoid buildup of foreign matter upon the wheel as the distance measuring apparatus is operated, wherein the scraper assembly comprises a body with a mounting leg that abuts to a bracket surface and a cleaning leg that projects in cantilever fashion from the mounting leg in a line extending generally in the first direction. - View Dependent Claims (30, 31, 32, 33, 34)
