Swinghandles - a customer/manufacturer design interaction By Andy Billingham – M.D. EMKA UK Ltd
O
nce upon a time there was – the L handle and the T handle which had been around forever and worked OK but had their limitations. So the people at EMKA who understood this considered an alternative approach.
Their design criteria included how to deal with the problems inherent in pro- truding handles like the L and the T which:
• catch on clothing
• are vulnerable to leverage vandalism • increase the cabinet footprint by projecting beyond the door
• are a cause of transit damage by pushing through packaging to scrape paint on adjacent equipment
• are limited by traditional design thinking in functionality, styling, manufacture and installation. Their new concept was for a low profile housing, with the mechanism integral to the escutcheon and a fold- ing handle submerged into the body of the lock - making it almost flush to the door and only accessible by key - thus dealing at a stroke with clothing safety, vandalism and transit damage issues. This also freed designers to think fur- ther about how to deal with issues such as ease of installation, customisa- tion, variants and options, new styling cues and enhanced functions which became possible.
EMKA first introduced two basic models – the 1107 and 1125 programs which the UK enclosure market took a liking to for their solid feel along with their new fresh look and modular design approach, which also repre- sented a massive advance over the traditional L and T handle designs. 1992 saw the 2100 series developed for a reduced cabinet footprint to max- imise space in server rooms etc with the

protrusion of the handle being reduced by up to 50%. With this handle also came advances in rod systems to offer flexibility with cost savings, as hook rods and twisted-rod systems were added to the standard flat-rod system. By 1994 we had the first version of the 1150 in its basic two size options as cus- tomer individuality became even more of a driving force leading to the 1160, 1180 and the 2400 series in the late 1990’s. In the background, there contin- ued to be a steady increase of options for the 1150, originally in zinc die, to include variants in polyamide and polyamide/zinc die. Again reflecting market need, this process included the development of Stainless Steel swing- handles especially for the UK market. These new modular ranges brought forward a wealth of new design func- tionality which included miniturised versions, digital code locks, shuttered cylinders, padlockables and ultimately electro-mechanical release mecha- nisms. Ultra-low profile escutcheons were developed which blend smoothly into the door contours and new stan- dards were set in simplified hole punchings and mounting systems to speed and simplify assembly in the pro- duction and installation processes.

With the 2400 program the cycle came full circle when customers demanded larger exterior handles with the mecha- nisms moved from behind the door as far as possible while retaining the basic conceptual and practical advantages inherent in the swinghandle approach. The introduction of the 1190 Lift Handle moved away from the tradi- tional up-and-down rod movement to a lever handle moving a single rod in one direction - further narrowing the space required for installation. IP sealing requirements continued to push devel- opment especially in the 2600 program which enables the customer to have a limited area for the rods outside the sealed area and all the operating system of the handle on the front of the door. By 2000 new demands were on the agenda of specialist cabinet users – in particular the demand for electronic security systems This was met when EMKA introduced single point elec- tronic locking with a solenoid to suit the well established 2100, very quickly followed by the 1180 and the 1154. A full network solution giving remote monitoring and operation of cabinets within a data centre went further including special handles to include operating keypads.
Popularity of the 1125 called for an easily interchangeable electronic option with the same mounting cut-out which became the 1150 range - with number of options to cover many sorts of hole cut outs already in common use and making the 1150 the most flexible handle in the EMKA range.

developments over 30 years
Coming right up to date customer requirements have now defined the 3000 series handle with self-contained power supply, wireless radio key and the ability to interface wirelessly with the EMKA electronic monitoring system, giving greater control in moni- tored workshops over machine control access etc.
All along has been been the issue of vandalism - and development of elec- tronic locking systems has given EMKA the ability to leapfrog ahead with the vandal resistant 1154 lock program suitable for use on roadside cabinets e.g. for telecoms. Visit EMKA at:
