GN 7247 Multiple-Joint Hinges Aluminum, Concealed, with Opening Angle of 180°


GN 7247 Aluminum Multiple-Joint Hinges, Concealed, with Opening Angle of 180°

Product description


Multiple-joint hinges GN 7247 are installed on the inside of flaps, hatches and doors to save space and ensure protection against vandalism. The hinge has a maximum opening angle of 180°, which provides optimal accessibility and avoids the blocking of escape routes by open doors, for example.

Use of this hinge type leaves housing exteriors free of attachments that do not match the design or that should be avoided entirely in the interests of fast and easy cleaning.

Multiple-joint hinges are typically used in pairs. For higher loads, e.g. from large doors, these can be supplemented with additional hinges. Four reinforced washers are supplied for assembly, which can be used with mounting screws of thread size M6.

Installation Position – Pivot Characteristics

Multiple-joint hinges can be installed on the housing with the slotted holes of the mounting flanges that are either perpendicular or parallel to the hinge axis. This results in the two pivot characteristics depicted.


Application Examples


Adjustment and Mounting Options


Multiple-joint hinges can be adjusted in three planes during installation. For example, this allows compensation for tolerances or establishing of required compressive forces for seals.
Two planes can be adjusted via parallel or perpendicular slotted holes in the mounting flanges. In the third plane, position corrections can be made using GN 7247.2 spacer plates.
GN 7247.4 spacer plates with tapped holes as well as GN 7247.6 mounting plates with threaded studs are also available for mounting the hinges. The latter can be welded on or inserted through the wall from the outside and fastened in place.
The holes d2 are used to accomodate clamping or positioning pins, making it easy to position the hinge. This also prevents unintended turning or slipping under load. The pins cannot be removed for subsequent adjustment.

Design Variants

Flaps, hatches and doors can be inset, surface-mounted or mitered. The maximum wall thicknesses and bend sizes for planned sheet metal constructions arise from the respective installation type.

The design variants shown represent standard installation conditions. If the installation position of the hinge is changed or one of the two wall thickness dimensions s or b are lower, the maximum achievable dimensions change independently of each other. This makes it possible in some cases to work with larger wall thickness dimensions than those specified with the same hinge size. A simple design check via CAD or a test setup is therefore recommended.

Construction Example


Load Capacity

The maximum load of the multiple-joint hinges specified below applies to the standard use cases and serves for orientation in the case of deviating applications. The resulting forces lead to slight elastic deformation, which can be compensated for by means of the adjustment options, if necessary.
