Window handle TRI 134

Designed for the hand

We took a closer look at the cavity of the gripping hand and found out: It is not a circle, not an oval and not a rectangle, but a softly rounded triangle. So we developed a new grip profile in bluestone with three sides. TRI 134 is "as made for the hand".

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.

Window handles - small design objects with great effect

Window handles are more than just practical operating elements: they are design objects. Especially on windows that you open several times a day, they have to meet a high level of technical requirements.

Window handles - technical equipment

The window handles are fixed to the window frame by the standardized 7 mm square pin. How deep the square pin must be pushed into the window to lock it depends on the thickness of the window. The required pin length can be easily measured in advance using a thin object, such as a knitting needle. To do this, push the knitting needle into the opening as far as it will go and mark the spot with your fingernail. If you now measure this distance with a tape measure, you will have the pin length.

In addition, window handles from Griffwerk are equipped with a plain bearing, for a durable, smooth and, above all, noiseless function. Without costly maintenance work!

Care instructions for stainless steel: Door handles, window handles and co.

High quality material with intelligent surface

GRIFFWERK does not limit itself to elegant design - we are proud of the inner values of our products. We only use stainless steel alloy 304, also known as "1.4301". Due to its composition, this high-quality steel - matt or polished - is rustproof with exceptional corrosion resistance and durability. Stainless steel forms a very thin protective passive layer, which rebuilds itself even after surface damage caused by chemical reactions.

Care spray for door handles

GRIFFWERK recommends using special stainless steel care sprays to care for and maintain the value of your stainless steel door handles and fittings. They clean intensively, have a dirt-repellent effect and thus maintain the value of your stainless steel door set, lever handles and door fittings. Please do not use any aggressive cleaning and scouring agents containing alcohol for cleaning - regardless of whether the stainless steel surface is matt, polished or shiny. Please note that the surface of the lever handle set can be damaged if it is exposed to unusual stresses, such as building dirt, sanding dust, aggressive vapors or salt water. Therefore, clean the lever handle set with a stainless steel care spray immediately after soiling.
