Measuring device

摘要

A measuring device that has an upper guide movably engaged with a lower guide. The upper guide is extendable relative to the lower guide in a first direction along a first axis, and retractable relative to the lower guide in a second direction along the first axis. The upper guide and lower guide form a straightedge that is adjustable. The measuring device includes one or more rulers and levels. A locking mechanism operatively engages with the upper guide and lower guide. The locking mechanism is configured to lock and maintain a position of the upper guide relative to the lower guide and unlock to allow extension and retraction of the upper guide relative to the lower guide. The units of rulers on the upper guide can increase along the second direction, and the units of the rulers on the lower guide can increase along the first direction.

主权项

1. A measuring device comprising:
a. an upper guide comprising an upper top surface and an upper bottom surface, wherein the upper guide further comprises a first upper end connected between the upper top surface and the upper bottom surface, a second upper end connected between the upper top surface and the upper bottom surface opposite the first upper end, and an end plate engaged with the first upper end, thereby forming an upper end straightedge; and b. a lower guide comprising a lower top surface and a lower bottom surface, wherein the upper bottom surface is movably engaged with the lower top surface, wherein the upper guide is extendable relative to the lower guide in a first direction along a first axis, wherein the upper guide is retractable relative to the lower guide in a second direction along the first axis, wherein the second direction is opposite the first direction, and wherein a first straightedge is formed along a first side of the upper guide, the lower guide, or combinations thereof; and wherein a position of the lower guide relative to the upper guide is maintained to form a template, wherein the template allows for repeated operations based upon a fixed length along the first axis defined by the upper guide and the lower guide.
