Transformation mechanisms

The transformation mechanisms МТД4 and МТД7 by JSC "Izmeritel" are used in forming the construction of folding sofas and armchairs. They help to lift up the soft piece of furniture opening the compartment for bed linen.

JSC "Izmeritel" produces three types of the transformation mechanisms МТД4. They differ from each other with a number of springs. МТД4 is a mechanism with one spring, МТД4-2 has two springs and МТД4-3 has three springs.

Their design features are presented in the table:

Spring model	Number of springs	The force of one spring at maximum strain F3, H	Weight, no more than, kg
МТД4-1	1	224	2,7
МТД4-2	2	224	3,0
МТД4-3	3	224	3,3

Specifications:

The mechanisms have colorless chrome plated zinc coating The complect of МТД4 and МТД7 includes the right and the left mechanisms. The weight of МТД4 is 1,8 kg, the weight of МТД7 is no more than 4 kg Each mechanism operates for opening and closing for no less than 6000 times
