Claims
- 1. An article for use with a flexible closure support, said article comprising:
- a shank having a first end and a second end, said first end having a first hole with a larger portion and a smaller portion, said larger portion and said smaller portion of said first hole lying in a plane, said second end having a second hole with a larger portion and a smaller portion, said larger portion and said smaller portion of said second hole lying in a plane;
- a roller assembly carried in said first hole and having
- a pair of wheels, and
- an axle joining said wheels,
- said larger portion of said first hole communicating with said smaller portion of said first hole with first means formed in said first end between said larger portion of said first hole and said smaller portion of said first hole for resisting movement of said roller assembly from said smaller portion of said first hole to said larger portion of said first hole; and
- a button assembly carried in said second hole and having
- a button,
- a stop, and
- an axle joining said stop and said button,
- said larger portion of said second hole communicating with said smaller portion of said second hole with second means formed in said second end between said larger portion of said second hole and said smaller portion of said second hole for resisting movement of said button assembly from said smaller portion of said second hole to said larger portion of said second hole.
- 2. The article as recited in claim 1, wherein said first resisting means further comprises a first passage between said smaller portion and said larger portion of said first hole said first passage being smaller than said smaller portion of said first hole.
- 3. The article as recited in claim 1, wherein said first resisting means further comprises:
- a first passage between said smaller portion and said larger portion of said first hole, said first passage being smaller than said smaller portion of said first hole; and
- means in communication with said first end for making said passage narrower when said roller assembly is moved toward said passage.
- 4. The article as recited in claim 1, wherein said first resisting means further comprises:
- a first passage between said smaller portion and said larger portion, of said first hole said first passage being smaller than said smaller portion of said first hole; and
- at least one cut-out portion communicating with said smaller portion of said first hole and oriented with respect to said roller assembly so that said first end flexes to make said passage narrower when said roller assembly is moved from said smaller portion of said first hole.
- 5. An article for use with a flexible closure support, said article comprising:
- a shank having a first end and a second end,
- said first end having a first hole with a larger portion and a smaller portion, said larger portion and said smaller portion of said first hole having a first passage therebetween, said first passage being smaller than said smaller portion, said shank having first means for enlarging said first passage temporarily,
- said second end having a second hole with a larger portion and a smaller portion, said larger portion and said smaller portion of said second hole having a second passage therebetween, said second passage being smaller than said smaller portion smaller said shank having second means for enlarging said second passage temporarily;
- a roller assembly carried in said first hole and having
- a pair of wheels, and
- an axle joining said wheels, said axle dimensioned to pass through said first passage when said first passage is expanded; and
- a button assembly carried in said second hole and having
- a button,
- a stop, and
- an axle joining said stop and said button.
- 6. The article as recited in claim 5, wherein said first hole has sides and said first enlarging means further comprises at least one cutout portion in space relation to said first passage of said first hole to weaken said sides of said first hole near said first passage so that said sides can flex outwardly and thereby enlarge said first passage.
- 7. The article as recited in claim 5, wherein said first hole has sides and said first enlarging means further comprises at least one cutout portion in spaced relation to said first passage and communicating with said smaller portion of said first hole to weaken said sides of said first hole near said first passage so that said sides can flex outwardly and thereby enlarger said first passage.
- 8. The article as recited in claim 5, wherein said first hole has sides and said first enlarging means further comprises two cutout portions in spaced relation to said first passage and communicating with said smaller portion of said first hole to weaken said sides of said first hole near said first passage so that said sides can flex outwardly and thereby enlarge said first passage.
- 9. The article as recited in claim 5, wherein said first hole has sides and said first enlarging means further comprises at least one cutout portion in spaced relation to said first passage and communicating with said smaller portion of said first hole to weaken said sides of said first hole near said first passage so that said sides can flex outwardly and thereby enlarge said first passage when said roller assembly passes from said larger portion to said smaller portion through said first passage but flex inwardly to narrow said first passage when said roller assembly is moved from said smaller portion toward said passage.
- 10. The article as recited in claim 5, wherein said first hole has sides and said first enlarging means further comprises at least one cutout portion communicating with said smaller portion of said first hole and deployed at an angle of less than 90 degrees with respect to said first passage so that said sides can flex outwardly and thereby enlarge said first passage when said roller assembly passes from said larger portion to said smaller portion through said first passage.
- 11. The article as recited in claim 5, wherein said first hole has sides and said first enlarging means further comprises at least one cutout portion communicating with said smaller portion of said first hole and deployed at an angle of less than 90 degrees with respect to said first passage so that said sides can flex outwardly and thereby enlarge said first passage when said roller assembly passes from said larger portion to said smaller portion through said first passage but flex inwardly to narrow said first passage when said roller assembly is moved from said smaller portion toward said passage.
- 12. The article as recited in claim 5, wherein said second hole has sides and said second enlarging means further comprises at least one cutout portion in spaced relation to said second passage of said second hole to weaken said sides of said second hole near said second passage so that said sides can flex outwardly and thereby enlarge said second passage.
- 13. The article as recited in claim 5, wherein said second hole has sides and said second enlarging means further comprises at least one cutout portion in spaced relation to said second passage and communicating with said smaller portion of said second hole to weaken said sides of said second hole near said second passage so that said sides can flex outwardly and thereby enlarge said second passage.
- 14. The article as recited in claim 5, wherein said second hole has sides and said second enlarging means further comprises two cutout portion in spaced relation to said second passage and communicating with said smaller portion of said second hole to weaken said sides of said second hole near said second passage so that said sides can flex outwardly and thereby enlarge said first passage.
