Abstract
Abstract A molding pin is disclosed adapted to form a light-reflecting area in a reflector having a tri-faceted forming end provided with the configuration of three adjacent facets of a rectangular parallelepiped. The three facets are mutually perpendicular to each other, and at least two of the facets are rectangular with two adjacent sides of each rectangle being unequal. In use, the pin may be combined with other like pins to form a bundle from which a reflector or reflector mold is made.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
59 words
A pin adapted to form a light-reflecting area in a reflector comprising a shank portion terminating in a tri-faceted forming end having the configuration of three adjacent facets of a rectangular parallelepiped, said three facets being mutually perpendicular to each other, and at least two of said facets being rectangular with two adjacent sides of each rectangle being unequal.
Claim 2
Dependent Claim
59 words
A pin adapted to form a light-reflecting area in a reflector comprising a shank portion terminating in a tri-faceted forming end having the configuration of three adjacent facets of a rectangular parallelepiped, said three facets being mutually perpendicular to each other, and at least two of said facets being rectangular with two adjacent sides of each rectangle being unequal.
Claim 3
Dependent Claim
60 words
The pin of claim 1 in which said shank portion has a rectangular cross-section, two of the three facets of said tri-faceted forming end converge to form an intersecting line and define said two rectangular facets, and the third facet extends from said two rectangular facets rearwardly of the pin in a direction along a side of said forming end.
Claim 4
Dependent Claim
21 words
The pin of claim 2 in which the longitudinal central axis of the pin is substantially perpendicular to said intersecting line.
Claim 5
Dependent Claim
25 words
The pin of claim 1 in which the longitudinal central axis of the pin is substantially parallel to the body diagonal of the rectangular parallelepiped.
Claim 6
Dependent Claim
77 words
The pin of claim 1 in which said shank portion has a hexagonal cross-section, two of the three facets of said tri-faceted forming end converge to form an intersecting line subtending an acute angle with the longitudinal central axis of the pin and to define said two rectangular facets, and the third facet extends from said two rectangular faces rearwardly of the pin in a direction to intersect two of the six sides of the hexagonal cross-section.
Claim 7
Dependent Claim
30 words
The pin of claim 1 in which the longitudinal central axis of the pin is substantially perpendicular to the plane of a face of a reflector formed with such pin.
Claim 8
Dependent Claim
40 words
The pin of claim 1 in which the three facets form three intersecting lines having a common point, and the longitudinal central axis of the pin is substantially parallel to a line subtending equal angles with said three intersecting lines.
Claim 9
Dependent Claim
59 words
The pin of claim 1 in which said shank portion has a rectangular cross-section and an end facet disposed at right angles to the central longitudinal axis of the pin, the remaining two facets extend from said end facet rearwardly of the pin in directions along two adjacent sides of said forming end and define said two rectangular facets.
Claim 10
Dependent Claim
70 words
The pin of claim 1 in which said shank portion has a rectangular cross-section, one facet is disposed at a right angle to the central longitudinal axis of the pin, and the remaining two facets extend from said one facet rearwardly of the pin and converge toward one another to form an intersecting line substantially parallel to said central longitudinal axis, said remaining two facets defining said two rectangular facets.
Claim 11
Dependent Claim
25 words
The pin of claim 5 in which the longitudinal central axis of the pin is substantially parallel to the body diagonal of the rectangular parallelepiped.
Claim 12
Dependent Claim
30 words
The pin of claim 5 in which the longitudinal central axis of the pin is substantially perpendicular to the plane of a face of a reflector formed with such pin.
Claim 13
Dependent Claim
40 words
The pin of claim 5 in which the three facets form three intersecting lines having a common point, and the longitudinal central axis of the pin is substantially parallel to a line subtending equal angles with said three intersecting lines.
Claim 14
Dependent Claim
22 words
The pin of claim 1 in which said two rectangular facets are equal in size, and the third facet is a square.
Claim 15
Dependent Claim
15 words
The pin of claim 1 in combination with other like pins to form a bundle.
Claim 16
Dependent Claim
56 words
The pin of claim 1 in combination with other like pins to form a bundle, said bundle comprising at least two rows of said pins, one row being superimposed over the other, and the pins of said two rows being longitudinally positioned with respect to each other to expose only said forming ends of said pins.
Claim 17
Dependent Claim
77 words
The pin of claim 1 in combination with other like pins to form a bundle, said bundle comprising at least two rows of said pins, one row being superimposed over the other, the pins of each row being aligned to place their forming ends adjacent one another, one row being displaced with respect to the other in a direction longitudinally of the pins to expose a lateral surface of at least one pin of the other row.
