Abstract
The invention relates to a sliding regulator, having a sliding slot which is closed without leaks against dust, etc., even in the immediate surrounding of the sliding member. According to the invention, this is achieved by a rubbery-elastic sealing lip associated with the sliding slot, which consists of a string of aligned lamellae attached to each other so as to form a flexible barrier against penetration of unwanted matter. The lamellae barrier deforms as the sliding member slides through it, so that the interface between the two remains substantially constantly sealed.
Claims11
A sliding regulator in combination with an operating unit, comprising a sliding slot in said unit, and having mounted within said slot a rubbery-elastic sealing lip for preventing penetration of unwanted matter, and further comprising a regulating member projecting through the sliding slot and the lip, and being movable along said slot, characterized in that said sealing lip is a one piece element and consists of a string of lamellae which are normally spaced apart from one another by gaps and are arranged substantially at right angles to the longitudinal axis of said sliding slot, adjacent lamellae of said sealing lip being connected in a bridge-type manner by a wall which closes said gaps to prevent penetration of said unwanted matter through said sliding slot, and wherein said lamellae are thicker than said walls.
A sliding regulator in combination with a unit housed within a panel, comprising
- a slot in said panel;
- a regulating member projecting through and slidable along said slot, said member engaging said unit within said panel and having a knob outside of said panel for manipulation;
- and
- sealing means positioned inside of said panel for sealing said slot along the length thereof while permitting said member to slide to any position along said slot, said sealing means having rubbery lamellae which extend substantially transverse to said slot and spaced apart by gaps, and wall material carried by said lamellae which substantially connect across said gaps and extending substantially parallel to the plane of said panel, said lamellae and said wall material having a flexibility so that said member can slide past them and so that they provide a form-fit within said member at any position it takes along said slot.
