Technical Forum

We want to clear up the main technical doubts that may arise regarding the assembly of our products and the necessary steps required to assemble them.

Hinges, stays and latches

Hinges and plates

Depending on the overlap you can choose one of these hinges:

Full overlay hinge: If you want to overlap practically the full side of the unit.
Half overlay hinge: If you want to overlap half the side of the unit.
Insert hinge: If you want the door to be inlaid hand therefore for the side of the unit to be seen.

What type of concealed hinge do I need to choose depending on the door overlap that I want to achieve?

Once you have chosen the type of hinge that you are going to use (straight, elbow or super elbow) you will have a formula for calculating the base or plates. This formula will the type B = 14 + D - O, where the variables are:
B = Height of the base or plates.
D = Drill distance from the hinge.
S = Door overlap with the side.

For example: We have a door with a thickness of 22mm, an overlap with a side of 15 mm (S) and a distance from the drill of 3 mm (D), we also know that the thickness of the unit board is 16 mm.
As the overlap is large, we will use the straight hinge. The formula of the straight hinge is B = 14 + D - O. We know the values D = 3 and S = 15. Replacing in the formula: B = 14 + 3 - 15 = 17 - 15 = 2.
So B = 2, with the straight hinge and the base is 2mm, the problem is solved.

How can I calculate the base or ideal plates for a concealed hinge?

The quantity of hinges needs for each door will depend on the width and height of the door, as well as the material that it is manufactured out of. In fact, it can vary in some specific cases.

The adjoined diagram can be used as a reference. where L is the distance between the hinges.

How can I know the number of hinges needed for a door?

The supplements or bases that are used along with the hinges have two holes for fastening to the furniture and a third hole for increasing the resistance of the hinge/supplement joint. It is especially designed for facilities that require more resistance such as on doors with pistons. 

In the following table you can see the length of the hinge arms on the side of the unit:

What is the length of the hinge arm on the side of the unit?

Stays and pistons

The following video shows how you can easily assemble a lifting piston.

We have a table for calculating the weight of a door, which is necessary to know when choosing guy ropes and measurements.

Depending on the material of the door, as well as its dimensions, the result will be the weight of the door (kg) that you can use to calculate to the necessary strength of the measure (Kg x cm).

A kilogram-force or kilopond, is the force exerted by 1 kg of mass by standard gravity on the earth’s surface which is 9.80665 m / s2.

1 kp = 1 kgf = 1 kg × 9,80665 m / s² = 9,80665 (kg x m) /s² = 9,80665 N

Therefore, kilogram-force or kilopond is what a mass of 1 kg weighs on the earth’s surface. That is to say, a kilogram-force or kilopond amounts to 9.80665 N

We use the concept of kilogram-force to specify the characteristics of dampers or pistons in our catalogue, however it is necessary to bear in mind that there are times when you can use one concept or another.

The following video shows how you can easily assemble the Miniwinch system.

The following video shows how you can easily assemble the Microwinch system.

The choice of a system for fold-down doors using a steel cable, like Microwinch or Miniwinch, depends on the height and weight of the door. To do so, you simply need to follow these simple steps:

1. Check the height and the weight of the door.

2. Once you have obtained the values, look up the selection table.

Depending on the weight of the door, you will be able to choose one fold-down system or another. Also, the table will indicate the number of systems needed for said door (x 1 or x2).

How can I choose a system for fold-down doors using a steel cable, like Microwinch or Miniwinch?

We have a table for calculating the pistons or dampners, where you can obtain a response with the furniture data.

The choice will depend on the width and the height of the door, as well as the material it is manufactured out of, in addition to the stroke of the piston or damper itself.

The result will be the number of pistons or dampners and the necessary strength of each one.

For the same force required in both folding and lift up doors, we recommend that you only use a single piston or damper in a door with a width of less than 450 mm, and that you use two pistons or dampers for a door that is wider than 450 mm.

The choice of a system for Agile lifting doors depends on the height and the weight of the furniture door. To do so, you simply need to follow these simple steps:

1. Check the height and weight of the furniture door.
2. Once you have obtained the values you need to calculate the strength of the spring, S = H * (W + 2 * Wh), in terms of:
H = Height of the door in mm.
W = Weight of the door in kg.
Wh = Weight of the handle in kg.
You can choose the lifting system according to what interval the strength of spring S falls under.
The LOW interval is between 580 and 1,250, MEDIUM between 960 and 2,040, HIGH between 1,800 and 3,500, and EXTRA HIGH 3,200 y 9,000.

For example, we have a door with a height of 400 mm and a weight of 5 kg, with a handle that weighs 0.22 kg.
The strength of the spring would be S = 400 * (5 + 2 * 0.22) = 2,176.
Therefore, we would choose the HIGH strength range because it is in the interval of 1,800 to 3,500.

The following video shows how you can easily assemble the Agile system.

Locks and latches

The Revalock child safety lock for doors and drawers is ideal for preserving child safety, as it prevents children from being able to open furniture. Among other things, it is very useful for installing in caravans or boats, ensuring they are locked.

Its installation and functioning is very simple, a magnet (key) deactivates the lock and makes it open. It is also possible to block it, so it stops working and it is not necessary to have a key to open it. This is very useful when it is no longer necessary.  

How is it possible to lock the Revalock child safety lock without having to disassemble it?
