TENSIONING PIN FOR SHUTTER SYSTEMS
First Claim
1. An improved tensioning pin system for shutter louvers, comprising:
- an elongated pin member separated by a dividing stop ring into a frame portion and a louver portion for interfacing with an aperture in a shutter louver; and
a ferrule member for engaging with an aperture in a frame member;
whereinone of said pin member and said ferrule member includes an annular catch channel and the other member includes an annular protrusion to engage with said catch channel when said pin member is slid into said ferrule member.

Abstract
A tensioning pin system (10) is provided for use in shutter-louver assemblies (12). The major component of the system (10) is a tensioning pin (50) in two mating parts; a pin member (52) and a ferrule member (54) which fit together and rotate with respect to one another. The pin member (52) is lodged within a louver slat (16) while the ferrule member (54) is firmly embedded into the shutter frame (14). The tensioning pin (50) maintains rotational tension for placement of the louver slat (16) and lateral separation between the louver slat (16) and the frame (14). A preferred interface between the pin member (52) and the ferrule member (54) includes an annular protrusion (80) mating with a catch channel (74) while alternate tension interfaces incorporate varying gradients on one of the members with a bead ring on the other member.

7. A tensioning pin system comprising:
-
a pin member being generally symmetrical about a longitudinal axis and having an elongated shaft separated by a stop ring into a louver portion and a frame portion having a cylindrical post; and a ferrule member adapted to slidably mate with said frame member, said ferrule member having a cylindrical tube defining a center bore to fit over said frame portion to snugly engage said frame portion while permitting tensioned mutual rotation therebetween. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)
