Foldable changing tables require precision work when it comes to calculating gas springs

The changing tables should slowly lower down and be able to be raised again without much force

At the Frankfurt Airport the company Knebel Metalltechnik designed and built in baby diaper changing tables that can be folded. This space saving model also protects the diaper changing tables, as they are folded out only when needed.

This type of diaper changing tables, however, presents the manufacturer with special challenges: When opened, the flap may not just suddenly drop down and the closing has to be supported as otherwise it would require too much force to lift the flap. Here a gas spring is the ideal solution.

BUT: the very limited space and the fact that the gas springs have to disappear completely when the table is closed made it difficult to calculate the appropriate gas springs and their exact fixing points. Discrepancies of millimeters would have prevented the perfect functioning.

When not mounted precisely to the millimeter, the gas springs will not work properly.

The gas springs have been calculated so that they behave force-neutrally when the flap is open.

Our technical customer service not only calculates the correct gas spring, but also supports the customer in the design process

With the help of the DICTATOR calculation program, the exact fixing points are calculated in close consultation with the customer. In addition to the gas spring, the fixing accessories required in each case are also defined. The result of the free calculation service for our customers: gas spring type with suitable manual forces and the exact fixing points for perfect function.

The co-workers in the technical customer service not only calculate the correct gas spring but also help with constructional advice.

Products used

Pull type gas springs

Pull-type gas springs

The DICTATOR pull-type gas spring range is mainly used in applications where the installation of a normal gas spring is not possible or not convenient, for example for space reasons. They work using the opposite principle to the pull-type gas springs, i.e. the gas pressure in the cylinder pulls the piston rod inwards. Examples of applications are flaps, windows and hatches that open mainly downwards.
