ECO Horizon door hinges are designed for heavy loads Door hinges not only bear the weight of the door itself, but much higher loads as well, depending on where they are used. In schools and nurseries, for instance, day-to-day use involves frequent opening of doors, door slamming and exceptional stresses. In such situations, conventional hinges can quickly reach their load limit if they are only designed to han- dle the door weight. ECO Horizon hinges, on the other hand, go above and beyond the standard in a number of ways. They have a closed, laser-welded hinge knuckle which prevents the knuckle bend- ing open. We haven’t compromised on the material thickness of the hinges either. Load-bearing capacity 200 kg Door hinges – Door stops, weights and loads 9 5 2 0 2 . 2 0

Hinge load factor Basics W 1000 Basics of choosing hinges When selecting a hinge, people often equate the load with the door weight alone. However, the actual load on the hinge can be many times the weight of the door, depending on a range of differen factors. Consequently, an additional reserve load should always be taken into account in any calculations. Exceptional loads often occur in public buildings such as nurseries and hospitals, as the doors are opened frequently and are subjected to unpredictable stresses. 5 3 4 1 X 0 0 0 2 H A properly measured, professionally designed stop in accordance with the ECO Schulte mounting instructions is always required. BBL BBL Reference values W H X Door leaf width: 1000 mm Door leaf height: 2000 mm Hinge gap: 1435 mm Reference data The load values indicated for our hinges are based on a maximum door weight. Additionally, the factors listed below, which impact the load on the hinges, must be taken into account individually. Factors that impact hinge load - Location of door - Door dimensions (residential building, public building, school, public administrative office, barracks, nursery, etc.) (extra-wide door, for instance) (wind load) - Alignment of the hinges - Doors that open to the outside - Type of material - Frequency of opening - Installation of the hinges - Door stop - Door closer - Swing leaf door operator - Door coordinator - Wall reveals, etc. 14 ECO SCHULTE SYSTEM TECHNOLOGY FOR THE DOOR 5 2 0 2 . 2 0

Hinge load factor Extra-wide doors W 1000 > 1000 The impact of extra-wide doors The load values are generally based on a maximum door weight and a door (1000 x 2000 mm) fastened with two hing- es (or sometimes with three hinges). Please note that the load on the hinges begins to increase disproportionately from a door width of 1000 mm.

Hinge load factor Third hinge A third hinge influences the load value of doors Positioning in the centre: The third hinge is frequently placed in the centre between the two outer hinges to create an aesthetic look and to ensure that the sealing pres- sure is evenly distributed. Placement in the upper third: In the case of extra-wide doors (> 1000 mm) or increased lever action on the door, the upper hinge requires additional support. In such situ- ations, the third hinge is positioned in the upper third of the door. This increases the load value. The DIN 18101 standard recommends fastening the third hinge 350 mm below the upper hinge. Additional support: A third hinge not only increases the load value; it also provides support. This is particularly important in situations where the door is subject to additional stresses, due to door closers or heavy traffic, for instance. High traffic For doors that are used frequently, we recommend installing an addi- tional hinge in the upper third. Door closer In doors with overhead door closers, the effective door weight increases by 20 per cent. Door closers with back-check increase the effective weight by a whopping 75 per cent. In such cases, we recommend a third hinge in line with EN 1935. Correct adjustment of the door closer is essential for ensuring that it continues to function properly over the long term. 241 350 350 X X BBL BBL BBL BBL BBL BBL 16 ECO SCHULTE SYSTEM TECHNOLOGY FOR THE DOOR 5 2 0 2 . 2 0

350 350 Door coordinator When a door coordinator is used on dou- ble-leaf doors, a damped locking mecha- nism must be installed in the active leaf. This is the only way to prevent the forces from being fully transmitted to the hinges. In this case, we recommend placing a third hinge in the upper third of the door. Electric motor drives for doors When using a swing leaf door operator, we recommend installing a total of four hinges, with one pair at the top and one at the bot- tom. The distance between the hinges in a pair should not exceed 350 mm. 350 350 BBL BBL BBL BBL BBL BBL 5 2 0 2 . 2 0 Door hinges – Hinge load factors 17

Hinge load factor Frame Proper, professional frame fixing Proper, professional installation of all components is absolutely nec- essary in order to achieve the maximum load value of a door hinge. The manner in which the door element is fixed to the wall is particu- larly important. Closed frames made of steel, aluminium or wooden materials are often intrinsically highly unstable. Close attention must be paid to how the frame is fixed to the masonry or to the substructure here. If a door weighs more than 60 kg, using only foam in this area is not recommend- ed. In this case, a frictional connection must be established using a screw or dowelled connection – either through the hinge attachment or at a point a maximum of 100 mm removed from the outer edge of the hinges. max. 100 max. 100 max. 100 max. 100 18 ECO SCHULTE SYSTEM TECHNOLOGY FOR THE DOOR 5 2 0 2 . 2 0

Hinge load factor Floor Floor seal A floor seal must be adjusted properly in order to prevent unnecessary additional loads on the lower hinge. In particular, pinching caused by the ‘trigger’ in the rebate area and excessively high pressure exerted by the seal against the floor are factors that must be avoided. 1 2 X 1 2 Floor clearance Sufficient floor clearance must be allowed across the entire opening angle of the door. For interior doors, DIN 18101 stipulates a nominal size of 7 mm for the air gap at the bottom of the door. For uneven or sloping floors, it may be necessary to adapt the floor clearance accordingly. From a technical perspective, it is normal for a door to sag slightly across the entire length of the opening angle; this sag depends on the door width, door weight and a number of other factors.

Hinge load factor Position Protruding wall reveals Factors such as protruding wall reveals, etc., can exert leverage if the door opens too wide; these factors are not generally taken into account. In such cases, the weight of the door can quickly cause damage to the fixing, hinge, etc. Recommendation – door closer with opening limiter: such as ECO TS-61 G H + ÖB Resting position Cutting-edge ECO Schulte door hinges are equipped with high-quality nylon friction bearings. The bearing technology used in these hinges meets the highest standards in terms of durability, freedom from mainte- nance and ease of movement. This ease of movement can result in the door moving independently, depend- ing on how and where the door is installed and the design and weight of the door leaf. Particularly in doors with multiple axes, it can be impossible to guarantee that a certain resting position – at 90° or 180°, for instance – will be maintained over the long term. Recommendation – door closer with hold-open device: such as ECO TS-61 with hold-open arm Door stop A door stop on the wall or the floor should be fitted at a distance of approximately 75 per cent of the door width from the hinge axis in the direction of the handle. Recommendation – do not use a door stop; select a door closer with an opening limiter: such as ECO TS-61 GS H + ÖB 1 2 75% Key 1 2 Door stop Distance to the door stop: approx. 75% 20 ECO SCHULTE SYSTEM TECHNOLOGY FOR THE DOOR 5 2 0 2 . 2 0

Models Horizon hinges Load-bearing stud The use of a load-bearing stud is recommended for additional stabili- sation of the hinge plates, depending on the area of application, design and load on the door. A load-bearing stud relieves the load on the fixing screws and stabi- lises the hinge plates in the door frame. This ensures that any forces are better absorbed and safely transferred into the stabilised frame. Please keep in mind that a load-bearing stud only provides additional stabilisation; it does not increase the load-bearing capacity. Safety bolt We offer hinges that are suitable for burglar-resistant doors. Multiple tests with various door elements have proven the effectiveness of these hinges. From resistance class 3 (in accordance with DIN EN 1627 et seq.) and up, the use of hinges with safety bolts is recommended. These welded-on bolts differ from bolted-on load-bearing studs in that they can absorb loads from levering tools in addition to providing extra stabilisation. 24 ECO SCHULTE SYSTEM TECHNOLOGY FOR THE DOOR 5 2 0 2 . 2 0

Leaf seals ECO Schulte Horizon hinges are also available as an FD (= leaf seal) model for soundproof doors with a leaf seal in the door leaf. These hinges have a groove for the continuous seal along the door overhang, so the seal does not need to be notched at the hinges. Highly resistant RC hinges The hinge plates, which are closed either on the outer edges or in the center, provide additional protection from break-ins and vandalism. It is impossible for them to slip out of the frame box.

Care instructions Stainless steel Stainless steel General care Stainless steel is the term used to describe certain types of particularly corrosion-resistant and hygienic steels. The surface is non-porous and does not require additional sealing. It cannot chip, and microorganisms and dirt do not stick to it. However, it still requires care and maintenance. Stainless steel has properties that make it an excellent material for an endless range of applications: High corrosion resistance, Heat resistance Full recyclability Food safety High material strength This stainless steel (1.4301 (X5CrNi18-10), AISI 304, (V2A), SUS304) is resistant to water, water vapour, humidity, acids in food, and weak organic and inorganic acids. It has a very broad range of potential appli- cations, including in the food industry, mechanical engineering, beverage production, the pharmaceutical and cosmetic industry, the manufacturing of chemical apparatuses, architecture, vehicle manufacturing, for household items, utensils, and appliances, for surgical instruments, and in cabinet and kitchen manufactur- ing. This Cr-Ni steel is not suitable for applications in chlorinated environments, nor is it suitable for use in swimming pools or seawater. Stainless steel is easy to care for, but it does still require some degree of maintenance. It must be rinsed off regularly with water (ideally lukewarm) and wiped down with a soft cloth. However, as a general rule of thumb, you should not use any abrasive cleaning agents. The milder the cleaning agents, the better. The cleaning agents must not contain hydrochloric acid, chlorinated ingredi- ents, etc. Sticky food residue should be removed with water-based detergents; fats and oils can be cleaned off using special alkaline and/or acidic cleaning agents containing surfactants. Fatty or lipophilic pigments are generally easy to remove with a neutral or all-purpose detergent. Stainless steel surfaces are easy to wash down, brush off or wipe clean with a damp cloth. However, please make sure to choose appropriate implements for man- ual cleaning. We recommend a microfi bre cloth. Apply the stainless steel care product (such as stainless steel care spray) and leave it on briefl y to allow it to take eff ect, then wipe off the surface with a cloth in the direction of the grain. If you need to clean coarse dirt off large surfaces, it is best to use brushes with natural bristles or special stainless steel brushes. Some nylon brushes contain abrasives, making these brushes unsuitable for stainless steel. All stainless steel surfaces that are touched frequent- ly need to be cleaned, disinfected and subsequently treated with stainless steel care products on a regular basis. Add detergent and disinfectant to the (ideally lukewarm) water. 30 ECO SCHULTE SYSTEM TECHNOLOGY FOR THE DOOR 5 2 0 2 . 2 0

The Alexanderplatz S- and U-Bahn station connects the hotel with Museum Island and the Brandenburg Gate, as well as with the different districts of the city. Alexanderplatz is emblematic of the diversity and contrasts of life in the big city. The cultural diversity and urbanity of Berlin also characterise the style of the Motel One Berlin-Alexanderplatz.

ECO reference project Infinity Office Düsseldorf, Germany The Infinity Office on Düsseldorf’s Schwannstraße, on the prestigious Ken- nedydamm, offers around 19,000 square metres of rental space on a plot span- ning just under 8,000 square meters. What makes this building so special is its free-form structure in a figure-of- eight shape. Here, modern architecture is linked with technical expertise: the building is designed to allow all users to concentrate 100% on their work. The professional planning, advice and sampling from ECO Schul- te were second to none, as was the holistic approach. All types of functional doors – both purely mechanical and automatic – could be implemented from the company’s own product portfolio. 5 2 0 2 . 2 0 Door hinges – Care instructions & glossary 33
