Description
Technical field
The present invention relates to a kind of furniture that is used to cushion/decay on being supported on pull-out guide and pull out the damping device of the retaining of parts when closing by noise.
Background technique
Being used to be buffered in the furniture that is supported on the pull-out guide, to pull out the retaining of parts when closing be known by the damping device of noise.
Known damping device is finally based on the piston-cylinder structure, Guan Lian shortcoming is therewith, these damping devices since essential the Sealing between piston rod and the cylinder with respect to blow-by, particularly after long working time or under the temperature of the limit and environmental conditions, be not have very much resistivity.
At this, the buffer stream of outflow is known from experience the surrounding environment that causes loss function and also can cause polluting buffer system in addition.
Because corresponding damping device is often with so-called combined from drawn-back device, should from function of drawn-back device be to those skilled in the art known and thereby here needn't describe in detail it, so known damping device is formed on function system with the high frictional force that it must occur---draw in certainly-significant interference parameter in the damping device, this is under disadvantageous situation even can cause no longer can making furniture pull out parts reliably from drawn-back device and close.Therefore, this interference parameter is often compensated by the elastic force in the raising in drawn-back device in practice, but this damages operation comfort again.
Summary of the invention
The objective of the invention is to, create a kind of damping device of same type, this damping device does not have aforesaid shortcoming and is trouble-free when operation and work with particularly not occurring disturbing frictional force basically yet.
Described purpose realizes like this according to the present invention, promptly, described damping device comprises sealing, a container that made by flexible material and that be filled with fluid or gaseous medium, this container is divided into one first chamber and one second chamber by a cross section contraction flow region, wherein, first chamber dwindles along the movement direction of furniture pull-out guide being pressed to piston on the container or analog from the outside by one aspect its volume, and second chamber can free expansion under the situation of the restoring force of setting up the chamber ladle cover.
The invention provides a series of advantage.
For example because the blow-by by the wearing and tearing decision can not appear in the fact of the complete closed of container own.Equally, unmanageable frictional force (as it occurring in the piston-cylinder unit) on Sealing or leather cup is inoperative.The fluid or the gaseous medium that are positioned at container needn't be born lubricated task.
Therefore, for example can expect using the liquid of economy, that is to say, can make water here as fluid with viscosity almost constant on big temperature range.The advantage that can realize thus will be a damping characteristics curve constant on big temperature range.
In according to damping device of the present invention, buffer function produces by the piston on first chamber from the external action to the container.Because this chamber can only reduce aspect its volume, be pressed into second chamber that the volume aspect can increase by the cross section contraction flow region so be arranged in the fluid or the gaseous medium of internal tank.Buffer function itself produces by the flow resistance in cross section contraction flow region zone basically.
If again to this damping device unloading, then fluid or gaseous medium are returned again owing to the elasticity in second chamber of its volume increase and are transported in first chamber.
A kind of simple especially structure regulation of the present invention, the cross section contraction flow region is by forming around ring container, constant diameter.
But can expect also that advantageously the cross section contraction flow region is by adjustable restriction, for example construct changeably via adjusting screw.Buffer function is changed.
Even can imagine, adjustable restriction is mechanically pulled out parts coupling connection with furniture, makes the adjustment of buffer function pulls out parts according to furniture loading condition obtain by the increase of restriction cross section.
Description of drawings
Embodiments of the invention shown in the drawings and being described in greater detail below.
Among the figure:
Fig. 1 illustrates and comprises from drawn-back device with according to the furniture pull-out guide of damping device of the present invention,
Fig. 2 to 4 illustrates according to the sectional view that schematically illustrate of damping device of the present invention under different running statees.
Embodiment
Mark on the whole with reference character 1 in Fig. 1 and be used for the pull-out guide that furniture is pulled out parts, this pull-out guide is equipped with in a manner known way from drawn-back device 2 and damping device 3.
Fig. 2 to 4 illustrates the structure and the mode of action of damping device 3 with schematic greatly view.
As finding out by these Fig. 2 to 4, damping device 3 basically by a sealing, container 4 that made by flexible material and that be filled with fluid or gaseous medium constitutes, the cross section contraction flow region that this container is a restriction 5 by a form in an illustrated embodiment is divided into one first chamber 6 and one second chamber 7.
It is inner and can be inserted piston 10 in this ladle cover pipe 9 from external load by one that first chamber 6 is arranged on a ladle cover pipe 9.At this, Fig. 2 illustrates piston 10 and bumps against first chamber 6, and Fig. 3 illustrates piston and exceeded definite stroke highway section and put in the ladle cover pipe 9 and at this first chamber 6 is reduced aspect the volume, because ladle cover pipe 9 stops first chamber 6 to be expanded.This compression by first chamber 6 is transported to fluid or the gaseous medium that is arranged in the container 4 second chamber 7 from first chamber 6 via restriction 5, and this second chamber can free expansion aspect volume.Therefore, restoring force R (see figure 4) is wherein set up simultaneously because fluid or the gaseous medium introduced increase in second chamber 6 in the ladle cover 7a of chamber aspect its volume.This process cause to the buffering of the pull-out guide 1 of the final couplings connection of piston 10.Fig. 1 is at the piston rod 10a of the piston 10 of analysing and observe damping device 3 shown in the part that illustrates.Be buffered in that pull-out guide 1 is closed or occur during indentation.If furniture is pulled out parts and is moved to open position against this again in the indentation direction shown in Fig. 2 and 3 now, then piston 10 is away from first chamber 6, thereby because fluid or medium that restoring force in the ladle cover 7a of the chamber in second chamber 7 can will be arranged in wherein most ofly return via restriction 5 again and be transported to first chamber 6, thereby this first chamber can be in its original size according to Fig. 2 again.
The backflow of the acceleration of medium or fluid for example can promote like this that promptly these two chambeies 7 and 6 for example join via a safety check coupling under the situation that gets around restriction 5.
Can find out that in fact damping device 3 does not have any member friction, that can have influence on buffer function unfriendly that causes.Be clear that equally damping device 3 does not have the lubricated member of needs that can move relative to each other.Therefore for example can make water as fluid in container 4 inside, this is economic solution on the one hand, causes the advantage of crossing over the almost constant viscosity of wide temperature range on the other hand.Cross over big temperature range thus and obtain in fact constant damping characteristics curve.
In an illustrated embodiment, as the top ground of having mentioned, damping device is the constituent element that yet comprises from the construction package of drawn-back device.
Spell out, damping device 3 but need not to be constituent element from drawn-back device, but also can affact fully independently on the rail system of pull-out guide 1.
At last, be yet that the damping device 3 that does not in fact have a Sealing also can be applicable in the applicable cases that high temperature and/or rodent environmetal impact play a role, for example in dishwasher according to one of damping device 3 of the present invention important advantage.
