Vacuum crevice nozzle with external guide pin
A vacuum crevice tool that uses a flattened nozzle attached to a circular vacuum hose and an external guide that runs along the nozzle and inserts into the crack being cleaned. It’s meant for cleaning narrow cracks in concrete, tile grout joints or similar crevices before sealing or grouting. Users are tradespeople or homeowners preparing joints for repair or grouting.
(57) What the patent covered
The main independent claim covers a crevice-cleaning nozzle with three elements: a circular cross-section tail that connects to a vacuum source, a flattened nozzle tip for placement next to a crack, and an externally mounted, parallel guide assembly at the nozzle’s end that has a head portion and an elongated portion sized to extend into the crack to guide the nozzle.
The distinctive part: Adding an externally mounted, parallel guide (a head plus an elongated probe) on the nozzle to insert into the crack and steer the crevice tool.
Making it

Before you make it
We didn't find any related continuation or divisional patents still in force, although that doesn't rule out design patents, trademarks or unrelated patents covering the same product.
Patent has lapsed; product is mechanically simple and crowded—watch for similar prior-art designs and functional vagueness in the specification.
Owners occasionally revive lapsed patents (about 1.5% are), and this page is a research lead rather than legal advice, so get a freedom-to-operate opinion before you manufacture anything.
