x lever

x lever by carl trenfield from uk

designer's own words:

through a process of reduction, the intention was to create a lever that is both traditional and elegant in construction terms, enabling suitable production runs whilst also aiming to address the needs of impaired users and ensuring that the product can be disassembled and subsequently recycled at the end of its life cycle.

the x lever takes its name from the rotating axis generated by the lever both vertically and horizontally around a central point.

the primary lever can be mounted vertically and horizontally through a standard 100mm vertical mortice latch. the second variant utilises an elongated bar that combines rotation with minimal effort and pull characteristics for minimum input by impaired users.

this process of reduction has resulted in the abolition of the traditional rose which is generally used to cover untidy holes made during lever and latch installation. this construction requirement has however been addressed through the introduction of a rebate to the base of the lever spigot, easing the handle from the surface and covering the necessary 5-6mm opening for the central spindle.

for user comfort, a circular stainless steel section, as opposed to rectangular, has been adopted.

although the initial design utilises a contrasting stainless steel bar with a burnished bronze (or similar) spigot, further colour options would be developed after consultation with Colombo Design to offer high visual contrast for visually impaired users.
