Definitions

• the present invention relates to a damping device for damping of
• damping devices are ultimately based on a piston-cylinder construction, which has the disadvantage that these damping devices are very susceptible to leaks, especially after a long time due to the required seal between the piston rod and cylinder
• escaping damping fluid can lead to loss of function and, moreover, also to contamination of the environment of the damping system.
• the present invention has for its object to provide a damping device of the generic type, not the aforementioned disadvantages has and that works without interference and in particular also largely without the occurrence of disturbing frictional forces during operation.
• the Dämpfungseinrich- device consists of a self-contained, consisting of a flexible material and filled with a fluid or a gaseous medium container, which is divided by a cross-sectional constriction in a first and in a second chamber in which the first chamber can be reduced in volume by a piston which can be pressed onto the container from outside onto the container or the like in the displacement direction of a furniture drawer guide, and the second chamber is underfloor
• Structure of restoring forces of the chamber shell can expand freely.
• the present invention offers a number of advantages.
• the damping effect is generated in the damping device according to the invention by the piston, which acts from the outside on the first chamber of the container. Since this chamber can only be reduced in volume, the fluid or gaseous medium in the interior of the container is forced through the cross-sectional constriction into the second chamber, which can be enlarged in terms of volume.
• the damping effect itself is essentially due to the flow resistance in the area of the cross-sectional constriction. If this damping device is relieved again, the fluid or the gaseous medium is conveyed back into the first chamber by the elasticity of the enlarged in its volume second chamber.
• a particularly simple construction of the invention provides that the cross-sectional constriction is formed by a ring surrounding the container with a constant diameter.
• FIG. 1 shows a furniture drawer guide with a self-closing device and a damping device according to the invention
• FIGS. 2 to 4 schematically show sectional views through a damping device according to the invention in different operating states.
• reference numeral 1 denotes a pull-out guide for a furniture pull-out part, which is equipped in a manner known per se with a self-closing device 2 and a damping device 3.
• Figures 2 to 4 show a highly schematic representation of the structure and operation of the damping device. 3
• the damping device 3 consists essentially of a self-contained and made of a flexible material and filled with a fluid or a gaseous medium container 4, which in the illustrated embodiment by a cross-sectional constriction in the form of a throttle. 5 is divided into a first chamber 6 and a second chamber 7.
• the throttle 6 can be adjusted by an adjusting screw 8 in its effective cross-section.
• the first chamber 6 is arranged within a cladding tube 9 and acted upon by a piston 10 which can be inserted into this cladding tube 9 from the outside. It shows
• Figure 2 shows the impact of the piston 10 on the first chamber 6, while Figure 3 shows that the piston 10 is retracted over a certain distance away in the cladding tube 9, while the volume of the first chamber 6 has been reduced, since the cladding tube 9 an extension of the first chamber 6 prevented.
• a fluid or a gaseous medium arranged in the container 4 is conveyed out of the first chamber 6 via the throttle 5 into the second chamber 7, which can expand in terms of volume. Consequently, we increase the volume of the second chamber 6 by the introduced fluid or gaseous medium, at the same time in the chamber shell 7a rear restoring forces R (see Figure 4) build. This process causes a damping of the piston 10 ultimately coupled to the pullout guide 1.
• Figure 1 shows in the section shown cut the piston rod 10a of the piston 10 of the damping device 3.
• the damping occurs when closing or when retracting the pullout guide 1 a. If, in contrast to this retraction direction, which is shown in FIGS. 2 and 3, a furniture extracting part moves back into the opening position, the piston 10 moves away from the first chamber 6, so that due to the restoring forces in the chamber casing 7a of the second chamber 7, the therein fluid or medium again to a large extent via the throttle 5 réellebe- can be promoted in the first chamber 6 so that they can resume their original size of Figure 2.
• An accelerated backflow of the medium or fluid can be promoted, for example, by the fact that the two chambers 7 and 6, bypassing the
• Throttle 5 for example via a check valve, are coupled.
• the damping device 3 has virtually no friction causing components, which could have a negative effect on the damping effect. It is also clear that the damping device 3 has no relatively movable components that would require lubrication.
• water can be used within the container 4 as fluid, which on the one hand represents an inexpensive solution and on the other hand leads to the advantage of a viscosity which is almost constant over a wide temperature range. This results in a virtually constant attenuation characteristic over a wide temperature range.
• the damping device is part of an even a self-closing device-containing assembly.
• a significant advantage of the damping device 3 according to the invention is that the practically seal-free damping device 3 can also be used in applications in which high temperatures and / or aggressive environmental influences play a role, such as in a dishwasher.
