Caulk working systems and methods with integrated cutting tool
View Patent ↗A caulk working tool for working caulk against first and second surfaces defining an intersection comprising a shaft member and a scraper body. The shaft member is substantially rigid, and scraper body is substantially resilient. The scraper body is molded over the shaft member and comprises a scraper surface defining a point and first and second sides. The scraper body deforms when the first and second sides are held in contact with the first and second surfaces. The caulk working tool is displaced relative to the first and second surfaces while the first and second sides are in contact with the first and second surfaces to cause the scraper surface to work the caulk against the first and second surfaces and form a desired profile in the caulk.
1. A caulk working tool for working caulk against first and second surfaces defining an intersection, comprising:
a shaft member, where the shaft member is substantially rigid; and
a scraper body defining a first portion, a second portion, an offset surface at a boundary between the first and second portions, and a scraper surface defining a point and first and second sides, where the scraper body is substantially resilient, and
is molded over the shaft member; whereby
the first portion of the scraper body is relatively thicker than the second portion of the scraper body;
the shaft member lies substantially within the first portion of the scraper body up to approximately the offset surface;
the second portion of the scraper body deforms between the offset surface and the scraper surface when the first and second sides are held in contact with the first and second surfaces, and
the caulk working tool is displaced relative to the first and second surfaces while the first and second sides are in contact with the first and second surfaces to cause the scraper surface to work the caulk against the first and second surfaces and form a desired profile in the caulk.
2. A caulk working tool as recited in claim 1 , in which the shaft member and the scraper body form a scraping subassembly, further comprising a cutting subassembly.
3. A caulk working tool as recited in claim 2 , in which the cutting subassembly may be moved between first and second positions relative to the scraping subassembly.
4. A caulk working tool as recited in claim 3 , in which:
the cutting subassembly comprises a blade defining an edge;
the edge of the blade is not exposed when the cutting subassembly is in the first position; and
the edge of the blade is exposed when the cutting subassembly is in the second position.
5. A caulk working tool as recited in claim 4 , in which:
the shaft member defines a blade slot; and
the edge of the blade is within the blade slot when the cutting subassembly is in the first position.
6. A caulk working tool as recited in claim 5 , in which:
the shaft member defines a blade opening; and
the edge of the blade is within the blade opening when the cutting subassembly is in the second position.
7. A caulk working tool as recited in claim 4 , in which:
the shaft member defines a blade opening; and
the edge of the blade is within the blade opening when the cutting subassembly is in the second position.
8. A caulk working tool as recited in claim 3 , further comprising:
at least one retaining slot formed in one of the shaft member and the cutting subassembly; and
at least one retaining projection formed in another of the shaft member and the cutting subassembly.
9. A caulk working tool as recited in claim 1 , in which:
at least one locator projection extends from the shaft member; and
at least one locator opening is formed in the scraper body; whereby
the at least one locator projection engages the at least one locator opening to inhibit movement of the scraper body relative to the shaft member.
10. A caulk working tool as recited in claim 1 , in which:
a plurality of locator projections extend from the shaft member; and
a plurality of locator openings is formed in the scraper body; whereby
the locator projections engage the locator openings to inhibit movement of the scraper body relative to the shaft member.
11. A caulk working tool for working caulk against first and second surfaces defining an intersection, comprising:
a shaft member, where
the shaft member is substantially rigid, and
at least one locator projection extends from the shaft member; and
a scraper body defining a first portion, a second portion, an offset surface at a boundary between the first and second portions, and a scraper surface defining a point and first and second sides, where the scraper body is substantially resilient,
is molded over the shaft member, and
at least one locator opening is formed in the scraper body; whereby
the at least one locator projection engages the at least one locator opening to inhibit movement of the scraper body relative to the shaft member;
the first portion of the scraper body is relatively thicker than the second portion of the scraper body;
the shaft member lies substantially within the first portion of the scraper body up to approximately the offset surface;
the second portion of the scraper body deforms between the offset surface and the scraper surface when the first and second sides are held in contact with the first and second surfaces, and
displacing the caulk working tool relative to the first and second surfaces while the first and second sides are in contact with the first and second surfaces causes the scraper surface to work the caulk against the first and second surfaces and form a desired profile in the caulk.
12. A caulk working tool as recited in claim 11 , in which the shaft member and the scraper body form a scraping subassembly, further comprising a cutting subassembly.
13. A caulk working tool as recited in claim 12 , in which the cutting subassembly may be moved between first and second positions relative to the scraping subassembly.
14. A caulk working tool as recited in claim 13 , in which:
the cutting subassembly comprises a blade defining an edge;
the edge of the blade is not exposed when the cutting subassembly is in the first position; and
the edge of the blade is exposed when the cutting subassembly is in the second position.
15. A caulk working tool as recited in claim 14 , in which:
the shaft member defines a blade slot; and
the edge of the blade is within the blade slot when the cutting subassembly is in the first position.
16. A caulk working tool as recited in claim 15 , in which:
the shaft member defines a blade opening; and
the edge of the blade is within the blade opening when the cutting subassembly is in the second position.
17. A caulk working tool as recited in claim 14 , in which:
the shaft member defines a blade opening; and
the edge of the blade is within the blade opening when the cutting subassembly is in the second position.
18. A caulk working tool as recited in claim 13 , further comprising:
at least one retaining slot formed in one of the shaft member and the cutting subassembly; and
at least one retaining projection formed in another of the shaft member and the cutting subassembly.
19. A caulk working tool as recited in claim 11 , in which:
a plurality of locator projections extend from the shaft member; and
a plurality of locator openings is formed in the scraper body; whereby
the locator projections engage the locator openings to inhibit movement of the scraper body relative to the shaft member.
