Mounting Element for Mounting an Architectural Covering Between Opposing Mounting Surfaces

A mounting element, for mounting an architectural covering between two opposing mounting surfaces, the mounting element comprising:

• an elongate mounting member which is elongated along a longitudinal direction and which has a first end, a second end, and opposed first and second guide surfaces extending in the longitudinal direction, and
• a telescopic extender arranged at one of the first end or the second end of the elongate mounting member, the telescopic extender being operable between a retracted configuration and an extended configuration so as to abut one of the opposing mounting surfaces when the mounting element is mounted between the opposing mounting surfaces, and
• wherein the telescopic extender comprises:
• a slidable body configured to slide along the first and second guide surfaces parallel to the longitudinal direction in a first translation direction away from the first end so as to lengthen the mounting element,
• a locking member mechanically coupled to the slidable body, the locking member including opposed first and second engagement parts that are movable to selectively engage the first and second guide surfaces, respectively, the locking member being configured such that:
• i) the slidable body is allowed to slide in the first translation direction when the locking member is unlocked, and ii) the slidable body is prevented from sliding in a second translation direction opposite the first translation direction when the first and second engagement parts are engaged with the first and second guide surfaces, respectively, and
• a release mechanism mechanically coupled to the slidable body, the release mechanism including first and second pushing portions configured for simultaneous rotation with each other, the first and second pushing portions being rotatable to displace the first and second engagement parts, respectively, relative to the elongate mounting member.
