Fold&Slide hardware – the new generation

Unlimited scope for architectural design, up to 130 kg
Fully-fledged technology
of a new generation of Fold&Slide doors

The new Fold&Slide hardware reveals­solutions that combine countless benefits.
As higher sash weights are permitted,­fewer individual elements are required
which guarantees maximum openingwidths. The larger glass areas allow daylight to flood into the room thus creating
an exclusive living atmosphere.
Unrivalled running smoothness,for sash weights up to 130 kgThe sashes are precisely and quietly
guided in the grooves of the running trackby ball-bearing supported, plastic-coatedrolls in the bogie at the bottom and guideroll at the top. Thanks to this technicallyinnovative combination, large and heavy
Fold&Slide sashes move safely and effort­
lessly. This means that window elements
up to 6700 mm wide with a single sash
weight of up to 130 kg ­can be used.
Barrier-free thresholdWith regard to the threshold, this new
Fold&Slide generation offers barrier
freedom as a standard solution – every
Fold&Slide system can be positioned using
the running track to obtain a barrier-freeversion (depending on the profile).
Enhanced security
Emphasis is placed on burglar inhibitionat the Fold&Slide element (among others)
where the screw connection of the sash
hinges is concealed and a UNI-JET central
locking system is installed at each individual sash.
Universally usable
Fold&Slide hardware is used in the public
sector and also particularly in the private
sector – e. g. to provide barrier-free accessin a private apartment to a terrace or
the conservatory. The open sashes canbe parked to the side in a space saving
manner, e. g. as an optimum solution for
the transition in a restaurant from inside
to outside.

Safety and convenience
Intelligent architectural hardware and burglar inhibition in harmony

Unique combination of bogie and guide rolls
The new generation of Fold&Slide hardware with a permissible
sash weight of 130 kg can reach element widths of up to 6700 mm.
More glass can be incorporated in window elements with large
sash widths of up to 1000 mm which allows light to flood intorooms.
Once opened, the sashes can be easily and conveniently moved
to the side and parked. This allows unrestricted use of the internal
living space and outdoor terrace space and also blurs the boundaries
between the two.
Sashes weighing up to 130 kg can be moved safely and conveniently using
an innovative architectural hardware; here an installation example
with an aluminium profile system

Six plastic-coated, ball-bearing supported rolls mounted in eachbottom bogie guide the sash precisely and quietly in the threegrooves of the running track. The guide rolls at the top of the sash
also feature two ball bearing supported plastic-coated rolls. Thanks
to this unique combination, even large and heavy Fold&Slide elements can be moved safely and effortlessly.
A brush seal seals the guide track on the floor which prevents dirt
entering the running track.

Increased burglar inhibition

The guide roll at the top in combination with the bottom bogie ensuresthat sashes can be operated quietly and effortlessly

The screw connection of the sash hinges provides increased burglar
inhibition and is elegantly concealed by metal cover caps. Thesecaps can only be removed when the sash is in the open position.
Horizontal adjustment range + 1.5 / - 5.0 mm
Vertical adjustment range+ 2.0 / - 2.0 mm
The GU sash hinges can for the first time be adjusted in two dimensions, horizontally and now also vertically.
The central locking system which can be installed on each indivi­
dual sash is another way to optimise burglar inhibition. The sashes
are also locked into the threshold at the bottom.
The optionally available opening and locked status monitoring­satisfies more stringent security requirements. If the magnetic
field that forms the connection between the components undersurveillance is interrupted, this is signalled via the alarm control
unit.

Barrier-free living
Space for unlimited possibilities

Barrier-free constructionin accordance with DIN 18040
The meaning of 'barrier freedom' in the true sense goes far
beyond the notion of making public and private rooms accessible to persons with physical limitations e.g. making public andprivate spaces available to wheelchair users so they can accessthese independently without the assistance of others. In fact,
it also defines situations that suddenly arise and can frequently
be ­encountered by anybody in everyday life in which personal
mobility is restricted by the specific situation. This could be a
person with a pushchair, or an injured sportsperson on crutches
or someone travelling with heavy bulky luggage.

Even heavy large sashes can be pushed effortlessly and safely to one sidein order to achieve the maximum obstruction-free passage width

Barrier-free construction increases safety and added conve­
nience for everyone: irrespective of age and health, the usefulness of a building and therefore quality of life is significantly
improved. This makes barrier-free construction not only a social
respon­sibility, it also makes a significant contribution towards
safe­guarding the future of a building and thus protecting the­investment in the long term. Barrier-freedom is becoming abasic requirement to be met by a building and products thatsatisfy these requirements will achieve commercial success.
Our new Fold&Slide hardware system satisfies these require­ments in every respect and is even available as a standard
solution: each Fold&Slide system can have a barrier-free design(depending on the profile) without requiring additional com­ponents such as a special threshold.
The flat GU system threshold can provide a ­maximum passage
width without obstructions. Frame parts that anchor the sash
to the floor do not represent a tripping hazard by projecting outof the floor when the sashes are parked at the side and instead
recessed in the threshold in the floor.
Even heavy large sashes can be effortlessly opened and moved
safely and to the side thanks to ball-bearing supported, plasticcoated rolls in the bottom bogie and the top guide roll. Not only
older persons or ­persons with restricted mobility appreciate
this, but also service employees in the gastronomy industry forexample, who value fast, short and obstruction-free routes in
the outdoor area of the restaurant.

Installation and quality
Tried-and-tested central locking system
and adjustable pivot rests / sash hinges guarantee optimum installation conditions

Central locking system
The central locking components required for the elements comefrom the successful UNI-JET Tilt&Turn hardware range. In this case,face-fixed or even fully concealed stay bearings and pivot rests canbe used. All locking points feature automatic cams which provide
ingenious clearance compensation.

Central locking system with Cleverle: simplified inventory management
due to tried-and-tested UNI-JET modular principle

The different climatic conditions in the summer and winterfrequently lead to changes in the locking cam settings. The selfadjusting Cleverle locking cam automatically adjusts clearance
tolerances, thus the adjusting effort during production or on site
is minimized. This significantly reduces the need for adjustment
during fabrication and thereafter.
By using standard components, this significantly reduces theinventory costs of fabricators of timber, PVC or aluminium windowelements.

Pivot rest
The pivot rests are accurately and securely fixed to the sash using
3 supporting bolts at 3 screw fixing points. The sash hinges areequipped with infinitely adjustable bearing pins and are therefore
ideal for adjusting the sash to suit a wide range of profile systems.
In addition to the wide horizontal adjustment range, large verticaladjustment is now possible for the first time.
Vertical adjustment range + 3.5 / - 1.0 mm
A scale helps make these adjustments quickly and precisely which
is a huge advantage with existing elements in projects.
Height-adjustable sash hinge, view from outside; the screw connection isconcealed from the outside which increases burglar inhibition

The sash hinges and pivot rests are suitable for all profile systems
with overlap heights between 15 and 26 mm – packers are notrequired!
Once installed, metal cover caps are fitted on the sash hinges andare extremely easy to remove again in order to make adjustments
at the open element.
