White paper on hinging from Elesa

White paper on hinging from Elesa Elesa are delighted to have increased their range of plastic, metal and stainless steel hinges with many standard variants, including specialist types. The Elesa range now includes:

The CF series - with the CF itself offering tamper-proof and double pivot hinges, as well as the CFH type in especially common sizes, and the 1/2 size CFG. Opening angles of 0-90°, 0-270° and 0-335° are provided in a piano hinge style but in larger sizes - this gives a unique interlaced appearance. The CFA/F offers blind fixing with a 90° stop to prevent over-opening of adjacent doors. Coupled with this, Elesa now offer the CFM surface mount hinge in reinforced polyamide based technopolymer and a companion version in die-cast zinc alloy. CFM hinges offer a variety of fixing methods and a full 270° opening for situations where it is useful to fold a door or access hatch fully out of the way.

Elesa, always renowned for innovation, have taken a new look at the humble hinge and now have a patent pending on the CFP hinge which has 3 pre-determined settings to allow fixed but temporary positioning of guards, doors, flaps or panels at 80°, 120° or 170°. Each position is held by a simple click spring mechanism, ensuring that one-handed operation is easily achieved, keeping the panel in position for ease of access in installation or maintenance.

A significant step toward equipment safety and integration is demonstrated by the CFS hinge for hazardous areas which has a built-in security switch to suit Category 1 areas and works so as to switch off equipment when a door or panel is opened. This is a great aid in industrial environments where it helps to ensure operator safety. Alternatively, the CFS may be used to remotely indicate status, e.g. for access monitoring. Construction is an integral glass reinforced technopolymer unit ensuring a tamper-proof installation and easy assembly.

Similarly, hinges with adjustable friction are a simple and really simple solution which allows users to set the opening force of the door so that it may stay partially open, or will dampen down the action of the wind in outdoor situations.

The Elesa 237 die-cast hinge are suited to all applications where greater strength and rigidity are required for doors on cabinets, panels or access hatches in the electrical, heating and ventilating or machine tool industries. The range offers hinge sizes in 40mm, 50mm or 60mm formats and features matt black epoxy coating with stainless steel hinge pins. Operation is to a maximum of 270°, which ensures full access by virtue of a wide angular opening, and fitment is easily achieved by use of 5mm, 6mm or 8mm countersunk bolts.

CMM hinges are in matt black finish with either studs or countersunk fittings and in sizes 40mm, 50mm and 60mm - their lay-on flap style design permits full 180° opening. Sister variant CMZ has the unusual feature of slotted hole fixings for cylindrical head screws which allows for a significant measure of adjustment up, down, or in rotation. The CMM-SST range of lay-on stainless steel hinges is designed for use on doors, panels and cases in the food and pharmaceutical industries - where their corrosion-resistance and easy-clean electro-polished finish will be much appreciated.

Of especial interest to designers and installers is likely to be the White Paper: Guidelines for the Application of Plastic Hinges which details the many parameters involved with guidance on their use.
