Multipoint locking as lightweight plastic locking systems
With the modular lightweight locking systems made of glass-fibre reinforced plastic, EMKA is launching an interesting innovation in the field of multi-point locking systems for control cabinets. The special feature: Thanks to a specially developed adapter, proven EMKA standard latches can also be combined with the system. This combination enables use both inside and outside the seal.
EMKA has added new components to its proven plastic connecting rod system for more flexible use on control cabinets. With the help of a newly developed adapter, all EMKA lever handles can be connected to the lightweight solution. If, for example, a bar lock is used, the H-profile plastic rods used can also be clipped to all EMKA key plates and swing handles without tools via the adapter. All locking components and rods are made of glass-fibre reinforced plastic.
Installation inside and outside the seal
The new EMKA system can be used inside or outside the seal. When installed outside the seal, at least two lock holders are required on the door frame. Since the system can be used for doors with a height of 800 to 2,200 mm, more or fewer locking brackets are used depending on the size of the cabinet. Depending on the door height and the resistance of the door seal, locking points can be set at intervals of 75 mm – a maximum of 16.
Inside the seal, the locking solution can be implemented with a three-point locking system. This consists of a bar lock with tongue in combination with a key plate or a swing handle. With the help of the newly developed adapter, these components can be connected to the H-profile plastic rods. The plastic connecting rods are simply clipped onto the locking element and fixed to the inside of the door with special rod guides. A run-up shoe at each end of the rod completes the three-point locking system. When opening and closing, this is inserted with a stroke of 23.5 mm into one locking plate at the top and one at the bottom. The door can also be changed without any problems. All that is required is to move the locking plates.
Another innovation of the door lock is the trapezoidal contour of the rod guide and lock holder. When these slide into each other, the door is aligned exactly horizontally when it is closed. This ensures that the door is always in the correct position in relation to the frame. Furthermore, the symmetrical arrangement of the locking components on the housing allows the door to be easily changed (right/left).
Less expensive than comparable systems
With locking components made of glass-fibre reinforced plastic, the experts from Velbert succeed in balancing robustness, efficient handling and significantly lower costs. In addition to corrosion resistance and durability, the lightweight closure system is also 30 % cheaper than comparable systems. The H-profile plastic rods are available in two lengths, but can be shortened quickly and variably due to the material. All plastic parts are produced in black as standard, but other colours, such as metallic silver, are also possible. The external components can be customised in terms of colour and logo printing.
