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 practical operating elements: they are small design objects with a big effect. Especially on windows that you open several times a day, they have to meet a high level of technical requirements.

In the Griffwerk range you will find window handles in different sizes and shapes as well as made of different materials. Thanks to our consistent design across all products, they are guaranteed to match the style of your door handles. So implement your design requirements down to the last detail - whether in matt or glossy, chrome-plated or brass-look, in velvet grey or graphite black. With our window handles, you can set the scene for your old windows or give your new windows the perfect design.

Window handles - technical equipment

The window handles are attached to the window frame by means of the 7 mm thick square pin. How deep the square pin must be pushed into the window to lock it depends on the thickness of the window. You can easily measure this in advance with the help of a thin object, for example 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 measuring tape, you will have the length of the pin.

In addition, our window handles are equipped with a sliding bearing for a durable, smooth and above all silent function. Without costly maintenance work!

Care instructions for stainless steel

High quality material with intelligent surface

GRIFFWERK is not limited to noble design - we are proud of the inner values of our products. We exclusively use stainless steel of alloy 304, also known as "1.4301". This high quality steel is - matt or polished - due to its composition stainless with special corrosion resistance and durability. Stainless steel forms a very thin protective passive layer, which rebuilds even after surface damage caused by chemical reactions.

Our care spray

GRIFFWERK recommends the "GRIFFWERK Care Spray", which is specially designed for our products, to care for and maintain the value of your stainless steel door handles and fittings. It cleans intensively, has a dirt-repellent effect and thus maintains the value of your stainless steel room door set, door handles and door fittings. Please do not use any aggressive cleaning agents or 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 under extraordinary stress, for example by building dirt, grinding dust, aggressive vapors or salt water. For this reason, clean the handle set with GRIFFWERK Care Spray immediately after soiling. Our GRIFFWERK care spray is available from all our trade partners.
