Abstract
Abstract A bearing formed by folding a sheet to create a hollow, cylindrical shell, bearing body for receiving a bearing shaft and flaps extending beyond the bearing body; means extending over a short length of the bearing body for holding the flaps of the folded sheet together to impart resiliency to the bearing body; a plurality of spaced projections on diametrically opposed locations in the interior of the shell of the bearing body, for being engaged by the bearing shaft, and for causing the bearing body to flex outward and to press inward against the bearing shaft, thereby to resiliently brake the visor against undesired reorientation.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
161 words
In a bearing including a bearing body comprised of a wall surrounding and defining a hollow opening; said wall having ends at the ends of said hollow opening; and said bearing also including a bearing shaft inserted in said hollow opening, the improvement comprising, said wall having a plurality of locations at various positions around said wall and each extending the length of said wall; a plurality of short length projections spaced apart from each other along said wall, spaced inwardly from said wall ends, extending lengthwise along said wall in a direction between said ends and said projections projecting from said wall into the hollow engaging the inserted said bearing shaft, thereby to brake relative rotation between said bearing body and said bearing shaft, along one said lengthwise wall location, said wall having two said projections spaced apart from each other; along another said wall location, said wall having one projection located to be spaced between the two said projections.
Claim 2
Dependent Claim
161 words
In a bearing including a bearing body comprised of a wall surrounding and defining a hollow opening; said wall having ends at the ends of said hollow opening; and said bearing also including a bearing shaft inserted in said hollow opening, the improvement comprising, said wall having a plurality of locations at various positions around said wall and each extending the length of said wall; a plurality of short length projections spaced apart from each other along said wall, spaced inwardly from said wall ends, extending lengthwise along said wall in a direction between said ends and said projections projecting from said wall into the hollow engaging the inserted said bearing shaft, thereby to brake relative rotation between said bearing body and said bearing shaft, along one said lengthwise wall location, said wall having two said projections spaced apart from each other; along another said wall location, said wall having one projection located to be spaced between the two said projections.
Claim 3
Dependent Claim
43 words
In the bearing of claim 1, wherein said bearing body wall defines a hollow opening of substantially cylindrical cross-section, the improvement further comprising, said wall locations for said projections being disposed along two diametrically opposed locations on said wall of said bearing body.
Claim 4
Dependent Claim
56 words
In the bearing of claim 2, the improvement further comprising, along the said wall location having two said projections, each of these said projections is located near one of the ends of said bearing body and along the other opposite said wall location, the single said projection is located near the middle of said bearing body.
Claim 5
Dependent Claim
156 words
In the bearing including a bearing body comprised of a wall surrounding a hollow opening and including a bearing shaft insertable in the hollow opening, the improvement comprising, a plurality of projections extending from said wall into the hollow opening for engaging the inserted said bearing shaft, thereby to brake relative rotation between said bearing body and said bearing shaft, said bearing body being formed of a folded sheet of material such that the bearing body is formed centrally of the sheet of material, and neighboring parallel flaps of the sheet material of said bearing body are formed to extend away from said bearing body; said flaps being at a distance from each other; each of said flaps including a respective contact area which occupies a relatively small portion of its surface area; said contact areas being in engagement with each other, thereby to define the minimum width of said hollow opening in said bearing body.
Claim 6
Dependent Claim
156 words
In the bearing including a bearing body comprised of a wall surrounding a hollow opening and including a bearing shaft insertable in the hollow opening, the improvement comprising, a plurality of projections extending from said wall into the hollow opening for engaging the inserted said bearing shaft, thereby to brake relative rotation between said bearing body and said bearing shaft, said bearing body being formed of a folded sheet of material such that the bearing body is formed centrally of the sheet of material, and neighboring parallel flaps of the sheet material of said bearing body are formed to extend away from said bearing body; said flaps being at a distance from each other; each of said flaps including a respective contact area which occupies a relatively small portion of its surface area; said contact areas being in engagement with each other, thereby to define the minimum width of said hollow opening in said bearing body.
Claim 7
Dependent Claim
36 words
In the bearing of claim 4, the improvement further comprising, said contact areas being defined by a respective indentation integrally formed in each of said flaps; each of said indentations being at substantially the same depth.
Claim 8
Dependent Claim
16 words
In the bearing of claim 5, the improvement further comprising, said contact areas being secured together.
Claim 9
Dependent Claim
23 words
In the bearing of claim 4, the improvement further comPrising, said contact areas being disposed near one of said ends of said wall.
Claim 10
Dependent Claim
34 words
In the bearing of claim 7, the improvement further comprising, said bearing shaft being insertable into said bearing body at one end thereof and said contact areas being located near that said end thereof.
