Description
The present invention relates to a kind of end-stop damper, it for example is used in the furniture manufacturing and especially is used in the door and drawer of furniture.
By the more known damping pieces of prior art, they are used to make the door and the drawer of furniture can mildly fall the terminal location that it is closed.Should prevent impact type here and thereby contact furniture part nocuously, restriction wearing and tearing and reach the effect that suppresses noise and bump.
Known damping piece mainly contains an elastomeric stopper, and it is fixed in the blind hole of a processing in furniture body.Retainer also can be bonded on the furniture body.This retainer is outstanding from the flat surface of furniture body, and reduces for example collision of furniture door of another furniture part by its elastic deformability.
Yet especially in wall hanging cabinet with the cabinet door that is installed on the horizontally extending rotary gemel and with the hinged lid in tool box in produce such problem, that is, cabinet door or instrument case lid impinge upon on the traditional damping piece that is placed with a huge momentum based on its deadweight.Damping piece does not have so strong impact of ability damping satisfactorily in this case.For this reason, these traditional damping pieces must get size design disproportionately big, can not complete closed cabinet door thereby cause.
Known this type of end-stop damper of abridgments of specifications by Japanese publication number 2001140530A.This known end-stop damper comprises a retainer of guiding in having the elongated damping body of openend and blind end.Damping body has an installation cavity to be used to install a slide block that is connected with retainer, establishes one or more slide planes on the outline of slide block, and they abut on one of the installation cavity inner wall section that sets for the damping body openend.Establish one on the end in slide block stretches into installation cavity and abut in the sealing device on the profile in the installation cavity.Slide block stretches into end and sealing device and the cavity of the interior profile formation of installation cavity in the installation cavity, applies one owing to the counter-pressure that raises and cause at the cavity inner air pressure in this cavity when slide block pressurizes on slide block.Cavity has the hole of at least one air that is used to overflow in order to lay down air pressure.
Damping in this end-stop damper stems from the mouth that is designed to the hole in the damping body blind end, and it selects very for a short time, so air is overflowed lentamente for the air pressure of laying down in cavity.The typical diameter in this hole is about 0.1mm.The damping of expectation because the end-stop damper of mass production adopts the casting die manufacturing usually, and is difficult in and makes so little hole in this manufacturing process, so can not be provided reliably.In addition, the dimensional stability problem that this aperture in fact when permanent the use, also occurs.This causes enlarging the aperture and thereby causes worsening damping.
The end-stop damper that the purpose of this invention is to provide a kind of the above-mentioned type is even its long-time use in simple in structure also guarantees effective damping action.
Purpose of the present invention reaches by the feature of claim 1.Dependent claims relates to favourable the further developing of end-stop damper of the present invention.
Stipulate in view of the above, damping piece and hole cooperating, it is to form a flow resistance by the air of overflowing in the hole.When using this damping piece, for the air volume that can make compression overflow lentamente not will mouthful or the hole select very for a short time.Exactly, the hole can be chosen as almost size arbitrarily, because air volume flows by damping piece and overflow in damping ground.Also can realize having the hole of diameter by casting die greater than 0.1mm.Therefore, for the damping that obtains to expect, extremely do not depend on the accurately diameter of regulation of hole, and depend primarily on the damping piece that is adopted.
Damping piece can comprise that a kind of porous material is as the air flow resistance.Adopt this material air by many narrow flow path, thereby obtain the flow resistance of expectation.
By concrete design, damping piece can have one with agglomerated material, foamed plastics, textile material, felt materials or similarly constitute the element that the material of air flow resistance is made.The material that has a whole series to be suitable for is available, they in workability, stability, by air in particle possibility of jamming and other materials aspect of performance distinguish to some extent.Yet the common ground of these spendable materials is that they can be flow through and make air-flow to meet with the resistance that causes in this end-stop damper internal damping.
The hole of flowing through can be located on the blind end of damping body.In this zone, described hole can made especially easily aspect the process technology.Here, the diameter in hole can be selected from greater than the internal diameter of 0.1mm to cavity.Damping piece can be contained in the fixed area of a design on damping body adaptedly, whole here air flow stream overdamp parts.If select the diameter of the internal diameter of cavity as the hole, then damping piece can directly be pressed in the damping body and the blind end that constitutes damping body.
Different with it or additionally, the hole can be located on the slide block.Because slide block to small part reaches in the outside area of end-stop damper,, the hole of processing on slide block overflow from cavity very well so guaranteeing compressed air.Can establish a hole along the processing of slide block bearing of trend for this purpose in slide block, it reaches in the cavity always.Damping piece can be contained in the fixed area of a design on damping body adaptedly, whole here air flow stream overdamp parts.Damping piece can directly be pressed in the hole in this case.
Can be advantageously aspect process technology, damping piece is contained in the hole back to that side of cavity.If fixed area can design in the hole back to that side of cavity, then damping piece can be adaptive rightly there.
Different with it or additionally, damping piece can be contained in the hole and face that side of cavity.Therefore fixed area is in the same side.Because the flow direction that air is predetermined, so also guaranteed secure fixation in fixed area.
Damping piece also can fit in the inside in hole.If design has the hole of diameter greater than 0.1mm, then this structure is particularly advantageous.
In order to make slide block shift out automatically basically or, on damping piece, establish a spring that is contained in the installation cavity until being rested on outflow location by furniture part stop at no load condition.This spring extrudes slide block to small part from installation cavity.Overcome spring force, this slide block also can easily push in the installation cavity.Damping at first reaches by the rising air pressure.
By a kind of particularly advantageous form of implementation, described sealing device comprises at least one flexible sealing lip.When the cavity inner air pressure that constitutes by the interior profile of sealing device and installation cavity in the end of being stretched into by slide block in the installation cavity raise, sealing lip was compressed against on the interior profile of installation cavity, constitutes a kind of airtight basically being slidingly connected thus.
A kind of efficient especially and meanwhile economic form of implementation constitutes like this, that is, the elastic packing lip tilts towards the direction of installation cavity blind end basically.Sealing lip to small part has spacing from the outline of slide block, and is arranged on the end that slide block stretches into installation cavity.
Although in order to make slide block have when pulling out or the negative pressure that produces in cavity when being extruded by spring still can be placed in maximum outflow location, sealing lip allows replenish air to flow in the cavity.Here, the sealing device elastic packing lip in the distance in installation cavity between profile and the slide block outline, when slide block to small part when installation cavity is pulled out, from the interior profile of installation cavity one spacing is arranged based on the negative pressure that in cavity, forms.Therefore the spacing distance between the outline of interior profile that air can be by installation cavity and slide block is gone into the cavity from the sealing lip by-pass flow.Can create the simple especially and guiding device that meanwhile slides efficiently of a kind of structure, for this reason, at least one projection of design on the inner wall section that installation cavity sets for the damping body openend, it contacts with one or more slide planes of slide block.With the sealing device of the slip guiding device that on the installation cavity inwall of damping body bottom, constitutes a supporting and sealing, make slide block guiding reliably in installation cavity.
In order to make slide block not exclusively pull out or to be extruded, in slide block outline and installation cavity, be provided with at least one projection between the profile by spring from installation cavity.When slide block to small part when installation cavity is pulled out, this projection retaining leans against that design on the projection on the inner wall section that installation cavity sets for the damping body openend.Therefore created a kind of device of stop limit efficiently in simple mode.
In order to simplify the assembling of end-stop damper, damping body can insert in the blind hole of furniture body for example.In order to limit the insertion depth of damping body in blind hole, damping body has a step to the small part annular on its outline that sets for openend.
For the reliable installation of spring, slide block to small part has one basically along the elongate grooves of its longitudinal extension processing in its end that sets for the installation cavity blind end, is contained in the interior spring of installation cavity and extend in this groove.
For the state that pushes at spring, make in end in slide block stretches into installation cavity and the installation cavity between the profile, the cavity of expanding owing to groove elongated in slide block minimizes, and a pin along the installation cavity longitudinal extension is shaped on the interior profile of installation cavity blind end.In the state pin that slide block inserts fully extend into the groove that described slide block extends longitudinally basically fully.
In addition, in order to push special ground, the position mounting spring of saving of minimized while of state cavity volume at slide block, the spring that is contained in the installation cavity can and be contained on its outline movingly by the pin guiding, thereby does not hinder spring travel.Meanwhile design a distance between the groove that can in pin and slide block, extend longitudinally, thereby spring is contained on the interior profile of groove movingly, and do not hinder its spring travel.
Cavity volume is minimized can be reached like this, that is, when slide block pushed basically fully, spring moved in the clearance distance between described pin and the groove and becomes a monoblock.
Retainer can have a stop head, it exceeds the fringe area of this opening in openend to the small part of damping body, and its retaining leans against on the fringe area when slide block pushes basically fully, and thereby the additional restriction of having stipulated slide block insertion depth in the damping body installation cavity.
By the simplest form of implementation aspect process technology, described slide block can be designed to one with sealing device.
In order for example the cabinet door removably to be fixed on fastening position on furniture body, retainer can have the quick acting device or the similar contact device of a magnetic, is used for the removably connection of end-stop damper.
Press the another kind of design scheme of end-stop damper, in order to reach the measure that purpose of the present invention takes be, retainer has the quick acting device of a magnetic or similar contact device, is used for removably being connected of end-stop damper and a connector.Under this cross section situation, can have enough damping ground and reach release continuously.Damping here is just in time so big, and end-stop damper can advantageously be used in furniture is made.Especially in this respect confirmed already advantageously to stipulate that the diameter in hole was less than 0.1mm.
Cross section, this hole is for needed application feature and be not true to type, thereby is difficult to make.Yet adopt this design feature might influence the flow behavior of variation targetedly, thereby realize end-stop damper damping well in the release stage.
