In the 1 to 8th is a two-fold partial synchronization ( 1 - 6 ) and a multiple partial synchronization ( 7 and 8th ) of a drawer slide of a full extension, showing only one of the two left and right rail systems 1 is shown, with carcass rail 2 , Middle rail 3 and drawer rail 4 , The one with this example left rail system 1 cooperating opposite right rail system of the drawer slide is not shown for reasons of simplification, but is identical to this.

Here are the middle rail in a first partial synchronization 3 and the two carriages 5 and 6 through a first gear or pinion 8th synchronized by positive locking.

In addition, in a second partial synchronization all rails, namely the carcass rail 2 , the middle rail 3 and the drawer rail 4 through another gear or pinion 7 synchronized by positive locking.

The two pinions 7 . 8th the two partial synchronizations are advantageous on a common axis 13 rotatably mounted, but run separately and independently of each other, so that between these sprockets 7 . 8th there is no synchronization.

The axis 13 lies on the middle rail 3 firm and protrudes from both sides of the vertical leg (see 3 ) of the middle rail 3 horizontally away. The two pinions 7 . 8th are on the axis 13 on the opposite sides of the vertical leg of the center rail 3 arranged.

According to 3 combs the pinion 8th each with a rack 9 . 10 the carriage 5 . 6 which racks 9 . 10 in the extension direction of the rails 2 - 4 on the carriage 5 . 6 extend.

According to 3 combs the pinion 7 each with a direct gearing 11 . 12 in the rail material of the carcass rail 2 and the drawer rail 4 itself, what gears 11 . 12 on a horizontal approach of these rails 2 . 4 are formed and in the extension direction of the rails 2 - 4 extend.

In 4 is a variant of 3 shown, with the two pinions 7 . 8th for the two sub-synchronizations again on a common axis 13 on the middle rail 3 are arranged, but with respect to the vertical leg of the center rail 3 on the same side, in this case the side of the pinion 8th of the 3 , The closer to the middle rail 3 lying inner pinion 8th has the same function as the pinion 8th of the 3 but that meshes further from the center rail 3 lying outer pinion 7 with vertically extending legs of the carcass rail 2 and the drawer rail 4 on which turn the gears 11 . 12 are formed.

A variant of 4 show the 5 in which the outer pinion 7 not directly with a gearing 11 . 12 in the material of the carcase rail 2 and the drawer rail 4 is engaged, but with one, laterally attached to the vertically extending legs rack 14 . 15 ,

A variant of 3 provides the 6 which is a pinion 7a having, with partial toothing and partial friction lining, so that the pinion 7a is structurally and functionally divided into two parts in its axial direction. The toothed part of the pinion 7a meshes with the teeth 11 . 12 on the horizontal leg of the carcase rail 2 and the drawer dens Rails 4 what teeth 11 . 12 occupies only a part of the width, as the gearing 11 . 12 of the 3 , The other part of the horizontal leg of the carcase rail 2 and the drawer rail 4 is in frictional engagement with the friction lining of the pinion 7a , With the pinion 7a with partial toothing and partial friction lining over its axial width can then be over the length of the rails 2 . 4 Once a form fit and once a friction, depending on specific requirements. The form-fitting intervenes when, for example, is lost by stress-induced deformation of the rails, the frictional engagement.

Another variant of the multiple-part synchronization show the 7 and 8th , Here are the middle rail in a first partial synchronization 3 and the respective carriage 5 . 6 over a simple sprocket 16 synchronized. In a second partial synchronization, the middle rail 3 , the drawer rail 4 , and the upper carriage 6 by a one-piece, stepped double pinion 17 with double teeth 19 . 21 synchronized different diameters. In a third partial synchronization, the middle rail 3 , the carcass rail 2 , and the lower carriage 5 by another, one-piece, stepped double pinion 18 with double teeth 20 . 22 synchronized different diameters. The pinions 17 and 18 are outside the middle level of the middle rail 3 stored in the axis 23 the simple pinion 16 lies, with the axes 24 . 25 the stepped pinion 17 . 18 have an approximately equal distance X to the middle plane. The distance of the pinions 17 . 18 to the pinion 16 in the extension direction of the rails 2 - 4 but can be different. The translation of the gears 19 . 21 and 20 . 22 is here for example at 1: 2.

In the 9 to 12 a full synchronization of a drawer slide a full extension is shown.

In a first variant of the full synchronization are the middle rail 3 and the carriages 5 . 6 over a simple sprocket 8th on an axis 13 synchronized on the center rail. In addition, at least one roller 26 . 27 . 28 . 29 every trolley 5 . 6 on its shell-side surface 26a . 27a . 28a . 29a serrated and meshes with a toothing of the carcass rail 2 or the drawer rail 4 , as well as beneficial in addition to the middle rail 3 , These teeth are here as corrugations in the material of the carcass rail 2 and the drawer rail 4 punched, but can also be in the form of additional racks. This corresponds to a synchronization of the carriages with the carcass rail and the drawer rail. Here, the horizontal rollers 28 . 29 and / or the vertical rollers 26 . 27 the carriage 5 . 6 be toothed.

In a second variant of the full synchronization is a one-piece, double gear 30 with two different gears 30a . 30b different diameter at the middle rail 3 over an axis 13 stored, which is fixed there. The smaller diameter teeth 30b of the double gear 30 is for synchronization between middle rail 3 and the carriage 5 . 6 the drawer rail 4 and the carcass rail 2 intended. The larger diameter teeth 30a of the double gear 30 is for the synchronization between the three rails 2 - 4 intended.

A completely different variant of full synchronization is with the 12 in the form of a pair of scissors 31 shown. The speed of the parts of the drawer slide, which are used to move the drawer, is regulated. This works on the principle of the laundry rack, wherein each part of the guide with a joint and its fixing points A-E of an additional element (scissors / clothes horse) is connected.

The scissors 31 is provided in the manner of a clothes horse, with a variety of scissors bars 31a - 31i which are hingedly connected via hinge points G and accordion-like apart and can be moved together again. All rails 2 - 4 and both carriages 5 . 6 are about fixation points A-E, for example on fixing rods 32a - 32e with the pair of scissors 31 connected.

Like from the 12 it can be seen, the fixing point A is fixed to the carcass rail 2 connected, the fixing point B with the lower carriage 5 , the fixation point C with the middle rail 3 , the fixing point D with the upper carriage 6 and the fixing point E with the drawer rail 4 ,

The fixing point A is thus fixed and immovable, since he with the (not shown) furniture body on the carcase rail 2 connected is. By the scissors reduction moves the fixation point B of the lower carriage 5 with only 25% of the speed of the drawer rail 4 , ie the drawer, out of the furniture body or into it. Due to the scissors reduction, the fixation point C of the middle rail moves 3 with only 50% of the speed of the drawer rail 4 , ie the drawer, out of the furniture body or into it. By the scissors reduction moves the fixing point D of the upper carriage 6 with 75% of the speed of the drawer rail 4 , ie the drawer, out of the furniture body or into it. Since the drawer itself at the drawer rail 4 is fixed, moves the fuser E and thus the drawer with 100% of the speed of the drawer rail 4 from the Furniture carcass out or into this.
