La presente invención encuentra aplicación en el equipamiento de cajones de persianas de lamas enrollables.The present invention finds application in the drawer equipment roller blinds.
Las persianas de lamas enrollables están normalmente empotradas en cajones que tienen una abertura inferior de salida de la persiana que está operativamente acoplada a carriles de guía para las lamas situados en los laterales de puertas o ventanas, utilizando para ello piezas de guiado, conocidas en la técnica como embudos de testero.The blinds of roller slats are normally embedded in drawers that have a lower opening output of the blind that is operatively coupled to guide rails for the slats located on the sides of doors or windows, using guidance pieces, known in the art as treasure funnels.
Como se conoce, actualmente se encuentra muy
extendido el uso de cajones de persianas construidos a base de
perfiles de pared, por ejemplo, a base de perfiles de plástico o
aluminio, con piezas laterales de testero en las que se montan
respectivos embudos para guiado y embocadura de las lamas desde la
abertura inferior del cajón hasta los respectivos carriles de guía
de la puerta o ventana, para de este modo garantizar una correcta
introducción de los perfiles dentro de los carriles de guía y
evitar el enganche de los extremos de las lamas cuando entran o
salen del cajón durante las maniobras de apertura y cierre de
la
persiana.As it is known, the use of drawers of blinds constructed on the basis of wall profiles, for example, based on plastic or aluminum profiles, with lateral pieces of testero in which respective funnels for guiding and mounting are currently widely used. mouths of the slats from the lower opening of the drawer to the respective guide rails of the door or window, in order to guarantee a correct introduction of the profiles inside the guide rails and to prevent the hooking of the ends of the slats when enter or exit the drawer during the opening and closing maneuvers of the
blind.
En la actualidad, estas piezas de embudo, moldeadas en plástico, están previstas bien como insertos o como piezas moldeadas en el propio testero lateral, empleándose por motivos de economía, materiales de plástico tales como poliamida y similares.Currently, these funnel pieces, molded in plastic, they are intended either as inserts or as molded parts in the side tester itself, used by economy reasons, plastic materials such as polyamide and Similar.
