ABSTRACT
Bistable
device, constituted by a toggle (1), composed of two levers (110, 111),
hinged to film hinges (112, 113, 114), which, by the elastic flexure of
an element, can extend itself and switch between two opposite rest positions.
One or more hooks protruding from said levers (110, 111) may be added to
realize push-pull latches for doors or panels.
In
a configuration, a male element (15), by pushing said two levers (110,
111) of said toggle (1), can switch it into a closed position and become
engaged by said hooks (604, 605). Said male element (15), by retracting
itself, can switch said toggle (1) into an open position and disengage
itself from said hooks (604, 605).
In
other configurations, command levers applied to said two levers (110, 111)
of said toggle (1) drive other mechanical elements, as electrical
contacts, and make them to switch between two distinct positions.
FEATURES
A toggle,
hinged to film hinges, by the elastic flexure of one of its elements, can
extend itself and switch between two opposite rest positions, performing
as a bistable device.
One
or more hooks can be added to said toggle, to realize various kinds of
closures and fasteners.
One
or more command levers can be added to said toggle, to drive other moving
parts, like electrical contacts in electrical switches.
Entirely
made of plastics, it may be integrated with other plastic parts, and may
be produced in the same injection moulding operation, at zero components
and zero manufacture and assembly costs.

Simulator
- Jaws closure |
Simulator
for easy geometrical dimensioning of the "Jaws" device: calculates and
displays the geometric shape of the device resulting from parameters set
by user; displays full opening and closing cycles, in order to "see" the
device working.
Generates
automatically the solutions which meet minimal requirements set by the
user, by combining variations of basic parameters (angles and dimensions),
and allows filtering of obtained solutions, in order to find the optimal
solution. |
