Construction and Materials
The SOSS Invisible Hinge is a unique hardware solution designed for concealed installation, providing a clean and uninterrupted aesthetic for doors and cabinets. Unlike traditional surface-mounted hinges, SOSS hinges are mortised into both the door and the frame, rendering them completely invisible when the door is closed.
The core construction of a SOSS Invisible Hinge involves two main leaf components that pivot around a central pin. Each leaf is designed to fit into a precisely routed mortise. When the door is closed, these two leaves interlock, with the pin acting as the axis of rotation. This clever design ensures that no part of the hinge mechanism is exposed from either the door face or the frame edge.
Materials used in the construction of SOSS Invisible Hinges typically include high-quality metals to ensure durability and smooth operation. Common materials found in their product lines are:
- Steel: Many SOSS hinges are manufactured from robust steel, offering excellent strength and wear resistance. This material is chosen for its ability to withstand the demands of frequent use.
- Brass: Certain models, particularly those aimed at decorative applications or specific environmental conditions, may incorporate brass components. Brass provides corrosion resistance and a classic aesthetic.
- Aluminum: Lighter-duty applications or specialized environments might utilize aluminum, which offers good strength-to-weight ratio and corrosion resistance.
The internal mechanism, including the pin and any supporting components, is also typically made from hardened steel for longevity. The precision machining of these parts is critical to the seamless operation and the "invisible" nature of the hinge.
SOSS offers a range of models designed to accommodate different door weights, sizes, and functionalities. Some models are specifically engineered for:
- Standard Inswing/Outswing Doors: These are the most common applications, designed for interior and exterior doors that swing open and closed.
- Hold Open Feature: Certain hinges include a hold-open mechanism, allowing the door to remain open at specific angles without the need for additional hardware like doorstops.
- 180 Degree Opening: Specialized hinges are available for applications where the door needs to open a full 180 degrees flat against a wall, further emphasizing the concealed design.
- Fire-Rated Applications: Some SOSS hinges are tested and certified for use in fire-rated doors, ensuring safety and compliance with building codes.
The installation of a SOSS Invisible Hinge requires careful measurement and precise routing of mortises into both the door and the frame. This ensures that the two halves of the hinge align perfectly and operate smoothly without binding. The design emphasizes a clean, flush fit, contributing to minimalist architectural styles and high-end interior design.
