Here at SPINE we solve complex problems through intelligent engineering.
Form follows function, aesthetics are dictated by technology and the
solutions their relationship offers. Science takes centre stage.
Inspired by the interaction between vertebrae, SPINE solves age-old
hinge limitations. Unencumbered by traditional parts and manufacturing
processes, we strive to out-think the competition. Globally patented, you
can be assured there is no substitute, so don’t accept one.
Continual flex appeal - SPINE hinges grip all day long, morphing to fit any
face shape, head size, all with the lightest of touch. Temples open and
close smoothly, gradually, without flicking and traditional “dead” points.
There are no screws loose here - because there are no screws used in
SPINE working mechanics. Accidental impacts are glanced off as SPINE
moves in all directions, absorbing and dissipating shocks thus greatly
reducing breakage.
Our pièce de résistance? Temples shut automatically.
Yes, they really do.
8. TECHNICAL SPECIFICATION
// MICRO INJECTION MOULDING (MiM)
And here’s the technical bit…
…in order to produce the engineering precision demanded by the patented SPINE hinge system, only the MiM metal
working process can be trusted to create such complex forms in one single operation, in this critical a volume.
In brief, the process involves taking finely-powdered metal, mixing it with a binder material and passing it through
a process known as injection mould forming, which employs an area of physics known as “rheology”, the study of
the flow of matter.
Materials using MiM and comparable techniques result in components relied upon by a broad spectrum of
industries; aerospace, automotive, medical and industrial. Why? Because the MiM method can produce parts
where it is difficult, or even impossible to efficiently manufacture these items by any other means.
This ability to combine several typically prohibitive operations into one fluid process, ensures MiM provides
numerous measurable savings, not only in the reduction of lead times but also the evasion of multiple processes
usually amplified by miniaturisation. But MiM is recognised as a green technology thanks to the significant
reduction in wastage compared to ‘traditional’ manufacturing methods, such as 5 axis CNC machining.
// SPINE CABLE & SPRINGS
The spun wire cable is the heart of the SPINE hinge and is produced
by the leading manufacturer in the world. It’s diameter is a mere
0.60mm and at full tensile strength can hold over 300kg.
The dual springs not only provide the pulling power of SPINE, but
they allow the articulation of the vertebrae and enables our unique
auto-shut mechanism.
// FRICTIONLESS VERTEBRAE
There are 5 working SPINE vertebrae constantly interacting
seamlessly with each other to create a 90 degree hinge opening.
As every element helps the other to take the strain, they rotate
only 18 degrees meaning they share the load, making wear
from friction virtually non-existent.
9. DESIGN DETAILS
// SIGNATURE TIPS
Each tip is precision laser engraved with the SPINE signature
pattern, taken from the negative space between the vertebrae.
Not merely a design detail, this also improves grip and
reduces slipping.
// HINGE FORM
Sometimes the most beautiful forms arise from engineering
solutions to complex problems. SPINE is the ultimate expression
of this process, whereby the aesthetic of the hinge has been
entirely dictated by new technology and functionality.
// SIGNATURE NOSEPADS
Taken directly from the SPINE monogram, our
signature nosepads feature on every metal frame
we make. Precision tooled, they are encased in the
highest quality silicone.
// SIGNATURE ENDPIECE
Design cues appear on every endpiece in the collection.
The curved grooves are machine milled to echo the front
housing of the hinge creating a seamless integration
of temple to front.
// SUN LENSES
Discreetly lasered with the SPINE logo, all our high performace
sunglass lenses are Category 3, so suitable for all conditions,
and come with an inner anti-reflective coating as standard to
minimise unwanted glare inside the lens.
// EYEWEAR STYLING
Form complements function, style is born from necessity and every
material is carefully considered. Handmade acetate meets milled
aluminium, stainless steel is stamped and in the case of the SPINE
hinge, precision micro-injected to bring the technology to life.
