DESCRIPTION

Introduction device

The invention relates to an introduction device for sliding doors, drawers, etc., with a damping installation and a spring, which act respectively, directly or indirectly on a loader, the loader being movable between an insertion position and a free travel position.

Such an introduction device is known. They are used to drag the drawers to the closed position. In this, the introduction device acts on the drawer in the last part of its insertion movement, and the spring pulls the drawer. In order to avoid a strong impact of the drawer in the closed position, the damping system acts against the direction of action of the drawer. The introduction device is also used, for example, in sliding doors, the sliding door being then dragged to the closed position. If the displaced unit (drawer, sliding door, etc.) now has a high mass, the introduction device has to provide a great damping force, in order to reliably reduce, in the relatively short damping path, the energy of the movement.

However, this leads to the displaced unit being braked abruptly, which is perceived as annoying. Therefore, the damping paths of the shock absorber used in the damping installation have been extended. A more massive dimensioning of the cushions is not desired for reasons of space.

Documents DE 201 20 112 U1, EP 1 700 985 A1 and DE 20 48 950 A1, show known introduction devices with damping installations. The aim of the invention is to achieve an introduction device of the type mentioned at the beginning, with which construction units with a high displaced mass can also be damped and inserted reliably, taking into account the limited mounting space available .

This objective is achieved, according to a first alternative of the invention, by means of an introduction device with two dampers, according to claim 1. The two dampers therefore act in such a way on the loader, which at least partially add up their available damping paths. . This lengthens the total of the damping path. Therefore, the braking of the displaced construction unit can take place over a longer path, and the energy of the movement can be thereby reduced continuously. As shock absorbers, small and robust construction units themselves can be used. This can also ensure sufficient stability of the system as a whole, without leaving the permissible limitations of the mounting space.

According to a second configuration of the invention, it can be provided, according to claim 2, that the damping system has two dampers, whose damping effect acts in parallel on the magazine. In this configuration, the damping effects of the dampers are added, without the mounting space of the introduction device being substantially increased. The dampers can be specially grouped together, depending on the available mounting space, so that it is used optimally.

In order to ensure the insertion device, according to the invention, a reliable function of the charger, it is provided that the charger is movable in a guide between the insertion position and the free travel position, and that the guide has a parking section , in which the magazine is depressed with respect to its orientation in the insertion position.

According to a preferred configuration of the invention, it can be provided that the dampers are coupled to a movable adjustment element. The two dampers can be coupled to each other easily and reliably using the adjustment element. In this, when it is provided that the adjustment element is linearly movable in a sliding guide of a housing, the adjustment element, and thereby the entire damping installation, is then further mechanically stabilized through the sliding guide.

A particularly preferred configuration of the invention may be characterized in that the dampers are configured in the form of liquid dampers, with a cylinder and a piston movable therein, because a piston rod has been attached to the plunger, and why the piston rods of the shock absorbers are movable in opposite directions. The shock absorbers are already in use as reliable construction parts, and can be obtained at low cost. In addition, with the prescribed travel paths of the piston rods a simple constructive form can be realized. In this, it can be provided that the piston rods are movable in parallel with each other.

Reliable transmission of force between the loaders can be achieved when one shock absorber is coupled to the charger, and the other shock absorber to a housing side support.

A simple and mechanically stable design results in the fact that the dampers are configured in the form of liquid dampers, with a cylinder and a movable piston inside it, because the piston has a piston rod attached to it, and because the piston rods piston shock absorbers act on it

direction, and it can also be provided that the two dampers are coupled to the loader by means of pivot bearings.

When it is provided that the shock absorber, or the shock absorbers are / are coupled to the loader by means of pivot bearings, and that the springs are coupled to the loader distanced from the bearing, then a turning moment acts on the loader. It can be used to move the charger to the free travel position. To minimize the cost of the parts, it is possible to use identical shock absorbers.

The invention is described below according to the exemplary embodiments shown in the drawings. Shows:

a second alternative of an introduction device, in a perspective representation; Y

the introduction device according to figure 5 in various operating positions, and in respective side view;

Figure 1 shows an introduction device with a housing 10. The housing 10 has a side wall 11, to which wall parts are connected on all sides. The side wall 11 and the wall parts enclose a housing enclosure, which can be closed with a cover (not shown). In this, the cover has a wall that is located parallel to the side wall 11. The cover and the housing 10 have screw housings 16, aligned with each other. Clamping screws can be introduced through them, and the introduction device can be screwed to a wall of a body, of a drawer, of a sliding door, etc.

A damping device has been mounted in the housing enclosure of the housing 10. This contains an adjustment element 20 and two identical shock absorbers 30. The adjustment element 20 is executed in the form of a carriage, which is linearly movable in the housing 10. For this purpose the housing 10 is equipped with a sliding guide 14. This is formed by the side wall 11, the cover wall of the upper horizontal edge of the housing 10, and a wall 13.2 that limits a spring housing 13. The adjustment element 20 can slide along these components.

As can also be seen in Figure 1, the adjustment element 20 is executed with two insertion housings 21. In them, the cylindrical outer contours of a cushion cylinder 30 can be introduced. The cylinders respectively have a surrounding groove 34 in which they are immovably attached in the axial direction to the adjustment element. The shock absorbers 30 have a piston rod 31, which is coupled to a piston. The piston is linearly movable in the cylinder enclosure, against a volume of air. The piston rods 31 are provided on one side with suspensions 32, which are formed on the piston rods 31, in the form of material agglomerations. As shown in Figure 2, the lower shock absorber 30 is attached with its suspension 32 on a support 15. The upper shock absorber 30 is pivotally connected to a magazine 40 with its suspension 32.

The loader 40 is executed as an injection piece of synthetic material, and has two stops 41 and 43. The stop 43 is attached to a spring element 42 of the loader 40. The loader 40 carries on one arm a locking piece 44. In addition, the charger 40 is equipped with a spring suspension 45, in which a spring 60 can be hung at its end. The other elastic spring 60, configured as a helical spring, is fixed on a spring suspension 13.1 of the housing 10, the spring 60 being arranged in the spring housing 13. In the area of the bearing 33, the locking piece 40 is equipped with stumps 46 on both sides. These are embedded in a guide 12. The guide 12 is equipped with a linear section 12.1 and with a parking section 12.2, said areas being formed by an angled groove 34, which has been incorporated into the side wall 11, identically, and with mirror symmetry, on the opposite wall of the lid. In these guides 12 they insert the stumps 46 and the locking pieces 44, arranged on both sides in the magazine 40.

The introduction position of the introduction device is shown in Figure 2. In this, a sliding door (not shown) is held in the closed position by a drag 51. The drag 51 is part of a fitting 50, which is fixed to the sliding door. The introduction device is mounted on the side of the body, for example in a cabinet.

Naturally, these components can also be mounted interchanged.

When the door is now opened, starting from the closed position according to Figure 2, the drag 51 moves with the door to the right in the plane of the image, and carries with it the magazine 40 in the stop 43. In this , the locking parts 44 and the stumps 46 slide in the guide 12. The spring 60 is tensioned, and the piston rods 31 are removed from their respective cylinders in opposite directions, until the operating position according to the figure is reached 3.

Then, the blocking pieces 44 exceed the guide zone 12.3, formed by the linear section 12.1 and by the parking section 12.2, there being a guide edge. Since the spring 60 fits into the magazine 40 spaced apart from the bearing 33, a turning time is generated in a clockwise direction.

That turning moment tilts the loader 40 to the free movement position shown in Fig. 4. This is made possible because the stumps 46 can be rotated in the linear section 12.1, and because the locking pieces 44 no longer prevent that rotation. . In the tilted position, the loader 40 is locked with the locking parts 44 in the parking section 12.2, with positive connection of shape and in the opposite direction to the introduction. The drag 51 then enters free movement, as shown in Figure 4, until the door is open.

When the door is closed, it can be moved in free movement until the carrier 51 trips over the stop 41. Since the stop 41 is located eccentrically with respect to the stump bearing 46, the locking parts 44 of the section of parking 12.2 when the drag 51 appears (see figure 3). The stop 43 then engages behind the drag 41. The spring 60 then pulls the drag 51, by means of the magazine 40, in the direction of the closed position. At the same time the shock absorbers 30 are activated. These slow down the traction movement of the spring 60. Figure 2 again shows the insertion position, in which the shock absorbers 30 are free of pressure.

An alternative configuration of the invention is shown in Figures 5 to 7. While according to figures 1 to 4 the dampers 30 are arranged in line, therefore the damping paths are added, and the damping percentage corresponds roughly to the damping percentage of a single damper 30, according to figures 5 a 7 the damping percentages are added together, and the damping path corresponds to the damping path of a single damper 30.

As Figure 6 shows, a housing 10 is used again, which approximately corresponds to the configuration of the housing according to Figures 1 to 4.

On the side wall 11, and on the cover wall, the same guide 12 has been installed again. In the spring housing 13 the same spring 60 has been placed again. With respect to the explanation of the reference symbols designating a the same components, reference is made to previous executions. Two identical shock absorbers 30 are placed in the housing 17 of the housing 10. The lower shock absorber 30 is secured in its groove 34 with supports 18 of the housing 10, so as not to move axially.

The upper shock absorber 30 can be linearly movable in the right direction. The shock absorbers 30 correspond to the shock absorbers 30 according to Figures 1 to 4. These are coupled to the magazine 40, with the suspensions 32 of their piston rods 31, by means of a respective bearing 33. In this, the magazine 40 has a hole in the bearing that is aligned with a hole in the suspension bearing 32. A support bolt for the formation of a bearing 33 is inserted through the bearing hole, being set in one bearing hole, and being rotatable in the other.

The magazine 40 corresponds in its function and form of action with that corresponding to Figures 1 to 4. Instead of the stump 46, in the guide 12 it is guided to the bearing support bolt 33. The spring element 42 is stabilized with an arm 47 relative to the arm of the magazine 40.

The form of action corresponds to that of Figures 1 to 4, however the damping device has a different function. When the door is opened, the magazine 40 moves to the right, and the piston rods 31 are removed in parallel. After exceeding the guide zone 12.3, the loader 40 swings to the free-moving position, and again releases the drag 51, as shown in Figure 7. Since the rotation of the loader 40 takes place around the axis of rotation of the bearing 33 of the lower shock absorber 30, the upper shock absorber 30 is linearly displaced a certain distance in the housing 10, which is necessary due to the identical design of the shock absorbers 30. The closing movement of the door, and the retraction of the drag 51 takes place analogously to the of Figures 1 to 4, with the difference that both dampers 30 are connected in parallel, and act simultaneously with a damping effect on the charger 40.
