Title
(EN) RATCHET ASSEMBLY FOR ELECTRIC FAN
(FR) ENSEMBLE CLIQUET POUR VENTILATEUR ELECTRIQUE
Abstract
(EN)
A ratcheting mechanism (15) for a fan having a base (11) and a head assembly. The ratcheting mechanism has a pivot (16) having a portion for coupling with the fan head assembly; a member disposed within a portion of the pivot; a extension portion having side walls spaced apart from one another, the pivot and member disposed between the side walls of the extension portion; a pin having a lower portion seated within a base portion of the extension portion, an upper portion of the pin resiliently placed against the collar; and a coupling placed through a central portion of the side walls and the pivot for compressing the side walls against the pivot to maintain a position of the fan head assembly and allowing bi-directional pivoting of the pivot relative to the extension portion in a range of greater than 45 degrees absent a tightening and a loosening of the coupling.
(FR)
L'invention concerne un système d'encliquetage pour ventilateur qui comprend un ensemble base/tête. Ce système d'encliquetage comporte un pivot doté d'une partie d'assemblage à l'ensemble base/tête du ventilateur; un élément placé dans une partie du pivot; une rallonge dotée de parois latérales montées à l'écart l'une de l'autre, le pivot et ledit élément étant disposés entre les parois latérales de la rallonge; une broche dont la partie inférieure est logée dans une base de la rallonge, une partie supérieure de la broche reposant de façon élastique contre le collier; et enfin, un assemblage monté dans une partie centrale des parois latérales et du pivot pour comprimer ces dernières contre le pivot et maintenir en place l'ensemble base/tête du ventilateur et permettre ainsi le pivotement bidirectionnel du pivot par rapport à la rallonge dans une plage supérieure à 45°, en l'absence de serrage et de relâchement de l'assemblage.
