Black is finding its way into architecture, whether on large window fronts, as entrance doors or in interior details. Griffwerk offers the right selection of black fittings. A special feature is the black shade developed by GRIFFWERK, inspired by the black of graphite. The material look is reminiscent of black graphite powder, the feel is surprisingly soft. Graphite black impresses with its unusual, velvety matt finish and soft surface. Graphite black accents can be repeated in the room. They have a very noble effect and do not stand for elegant refinement and luxury for nothing. Griffwerk offers graphite black design in various product categories, allowing a holistic design of any interior. Graphite black is close to the RAL colour RAL 9011 (graphite black). Whether door handle, window handle, handle shell pair or even just handle bar, what is important is a uniform interplay of different colour elements that emerges from a conscious colour concept.
Anatomy and movement patterns guide design
In the search for the perfect haptic experience, GRIFFWERK tested a wide variety of profiles in several studies. Finally, several criteria could be defined that are relevant for a "perfect" gripping experience:
The "perfect" profile corresponds to the hollow space,of the closing hand. This is three-sided for anatomical reasons and not round or rectangular
During operation, the angle of the closed hand is changed, as well as the position of the user in space. The closed hand is therefore "moved" on the door handle. It does not remain static. The edges must therefore be softly rounded to allow for movement play.
Most pressure is exerted on the upper contact surface. This is also the largest contact surface between the door handle and the hand. It therefore plays the most important role for the grip feeling. It is particularly pleasant if it is kept very wide, as is the case with TRI.
The upper contact surface should also be inclined towards the door. An angle that slopes gently towards the door corresponds to the natural posture of the wrist when operating a door handle. Thanks to the inclined angle, the wrist is not hyperextended when pressing the handle (as would be the case with a horizontal surface).
Door handle TRI 134 was developed based on these criteria.
A new classic
Door handle TRI 134 is one of the simple, minimalist design forms that fit any door and any architectural style. In addition to a shapely, restrained design, it offers exceptional gripping comfort.
Haptic in perfection
We have developed a profile cross-section with a "perfect feel". Anatomical requirements and movement patterns were taken into account. The gripping area now has three sides and thus corresponds exactly to the actual cavity of the gripping hand. This is not round but has a three-sided shape due to the joints of the hand.
The Greek pronoun "TRI" ("three" or "threefold") therefore became the eponym of the first handle introduced with the new profile.
Its shape literally nestles against the hand.
