You might think that when it comes to opening and closing, all the possibilities of hinges have already been exhausted. Not even close. JW Winco regularly succeeds in making improvements to its hinges, adding practical features and designs for niche applications.
For heavy-duty applications, for example, try hinge GN 237.3, a compact hinge that’s made of stainless steel. With a 180° range of motion, these devices can stand up to high-dynamic wear — regardless of the mounting orientation because of special shim washers.
Depending on the type, the hinge bands also have centering extensions that ensure a tighter fit, preventing sliding and eliminating the transverse forces that otherwise place heavy loads on the screws.
The hinge pin is secured against loss by a recess and supplied with lifetime lubrication. An asymmetrical band arrangement and the associated possibility of a third fastening hole proves its value, particularly when mounted in areas with thinner material cross-sections.
The hinge series GN 235, on the other hand, can be mounted with socket head cap screws. Its offset axis means it can still swivels by 180° without collision. Horizontal and vertical slots simplify the adjustment. Its hole pattern also corresponds to existing hole arrangements, making it easier to replace existing hinges.
Additional functionality is offered by hinges with variable friction and, in another Winco part, an integrated spring ensures independent return of the hinge. This special product range, which also includes integrated damping, indexing, and locking functions, is often expanded upon with new products.
One kinematic highlight is already available from JW Winco: the multiple-joint hinge with either a 4x, 7x or 10x joint mechanism, which opens flaps and shifts their position at the same time. The 180° is standard and the internal installation makes use of the slots.
The GN 7237 stainless steel multiple-joint hinges are installed on the inside of flaps, hatches, and doors to save space and ensure protection against vandalism. The hinges have a maximum opening angle of 180°, which provides optimal accessibility and avoids the blocking of escape routes by open doors.
With its design hinges GN 138, JW Winco offers solutions for appearance-sensitive applications: the closed hinge body of die- cast zinc hides the fastening screws and is available in various sizes — and soon in stainless steel.
