Description
Technical field
The present invention relates to a kind of device according to claim 1 and furniture according to claim 11.
Background technology
In furniture industry, for buffering that the furniture parts of admitting with movable manner is moved, known multiple different snubber, described snubber has the fluid that is contained in the snubber housing.For example can utilize air buffer to carry out work, in its snubber housing, be separated out a plurality of volumetric regions by a moving-member that can in the snubber housing, move.When buffering, for example under the situation that moving-member moves into, pressure reduces in the volumetric region that enlarges, and pressure raises in the volumetric region that dwindles.In this process, the motion of buffering displaceable furniture parts on a distance of being scheduled to.Moving-member and/or snubber housing can be designed to, and make the gas can be from a volumetric region overflow to other volumetric region to realize desirable buffering.The manufacturing of sort buffer device is complicated.Can not avoid in addition, in the duty that occurs usually, behind buffering course, cause the recoil of furniture parts through cushioning owing to the buffer arrangement structure.
Summary of the invention
The objective of the invention is: provide a kind of improvement to the motion of displaceable furniture parts buffering furniture and make simpler, the more reliable buffer of work.
Described purpose realizes by claim 1 and 11.Provide favourable expansion scheme of the present invention in the dependent claims.
The present invention is based on a kind of being used for by cushioning the next device that the motion of the furniture parts movable with respect to main body is braked, described device comprises housing, described housing comprises that one is used for the mobile chamber of the piston piece of movable guiding therein, described piston piece can engage with furniture parts, wherein, can obtain cushioning effect by described piston piece mobile in described mobile chamber.Core content of the present invention is, described device is designed to, in the routine that allows is used, in braking procedure by avoid in the overvoltage chamber can resilience fluid cushion, make counter-rotating not occur by the direction of motion of the resilient component furniture parts that cause, that be braked that in braking procedure, produces.
Have compressible buffer fluid, particularly for example in the known fluid buffer of the gas of air, in buffering course, the gas pressure in the diminishing volumetric region in the fluid buffer improves.Its reason is, and is particularly very fast when mobile at piston piece at this, because the compressibility of gas is by the motion compresses gas of piston piece or moving member.At this, the furniture parts that piston piece is direct or indirect with motion or to be cushioned is connected or the coupling of moving.
" routine of permission is used " should be understood to a kind of use, and this use occurs in the common use of furniture, particularly rationally/and the motion of displaceable furniture parts when correctly using.Particularly can consider following device, wherein be provided with the restoring device that is used for displaceable furniture parts, wherein the check mechanism that proposed of the motion utilization of displaceable furniture parts carries out under the situation that has buffering.Utilize restoring device should realize the controlled closing characteristics of displaceable furniture parts, or make displaceable furniture parts enter the position of complete closure with respect to main body.Restoring device for example can utilize retraction spring to work or work under action of gravity.Fluid buffer before this in theory may but the application do not adopted in the practice wherein for example only makes displaceable furniture parts move extremely slowly, be not conventional use of permission under meaning of the present invention.Its reason is, this time long, for example in the buffering course of the slow progress on minute magnitude, possible is not occur elastic fluid cushion in the overvoltage chamber.
In the routine of reasonably using or allow was used, in corresponding known fluid buffer, setting up a motion for furniture parts in the overpressured zone of snubber was conclusive overvoltage, and this can cause the recoil of displaceable furniture parts.This be because, in buffering course, produce elevated pressure gradually by the gas that is constantly further compressed in the overvoltage side of volume-diminished, wherein this pressure acts on the piston piece and is opposite with the direction of motion of displaceable furniture parts.When the motion of piston piece finishes, the maximum if this pressure becomes and reaction force descend owing to the kinetic energy of displaceable furniture parts significantly reduces, the recoil or the motion counter-rotating of piston piece or displaceable furniture parts then may occur, this point all is undesirable with following situation about imagining: thus displaceable furniture parts may not arrive the danger that its closed fully position existence causes damage.In addition, when displaceable furniture parts is in open mode, the inside of the easier displaceable furniture parts of making dirty of meeting.In automatic retracting device (Einziehautomatik) with restoring device, for example general use, displaceable furniture parts is at first travelled forward, just make furniture parts closed fully then, this point is disadvantageous equally.Displaceable furniture parts particularly is interpreted as elongator (Aussch ü be), drawer, door, valve, carriage, revolving door, swivel mount etc.
Utilization can make under the conventional situation about using above-mentioned resilience or so-called " recoil effect " not to occur according to device of the present invention.
Advantageously, can be according to the present invention at arranged outside overflow part section, for example cannelure of piston piece, the piston that for example can in the snubber housing, move.Because by avoiding setting up overvoltage, so needn't be on the piston piece or the possibility of fluid or gas overcurrent also may be provided on opposed section, for example inner walls in the front side of piston.In a word, can make snubber thus more economically.
The present invention proposes in addition, and described device is designed to, and makes cushioning effect only by being determined by the low pressure in first volumetric region mobile that form, that enlarge gradually of piston piece, the low pressure that particularly remains unchanged basically in described mobile chamber.Utilization is according to buffer of the present invention, though avoided the overvoltage side that exists before this or and described (overvoltage) side of can't help in the snubber housing determine buffering course, should (overvoltage) side in buffering course, on the direction of motion of piston piece, be positioned at piston piece the place ahead, promptly form the overvoltage side before this, still can control this buffering course at suction side.Suction side can particularly design as before this.Suction side particularly be present in piston piece with the opposed side of overvoltage side, this suction side is positioned at the piston piece rear on the direction of motion of piston piece in buffering course.By piston piece along or move away from the fixing wall portion of suction side, the volume of suction side is increased, wherein piston piece forms the wall portion of suction side equally.Externally almost isolating airtightly under the situation of negative pressure region, gas pressure increases along with the volume of suction side there and descends.The pressure drop of gas forms the basis of braking control or buffering control.
Can be arranged at this, in buffering course, on the suction side of buffer or low-pressure side, form low pressure that remain unchanged or that remain unchanged basically on the main motion path of piston piece.For example, minimum opening can be set, can realize less gas flow towards suction side, be the gas flow of unit interval via this opening.
In addition advantageously, can make the friction part section that on piston piece, exists be configured to the wall portion section CONTACT WITH FRICTION with mobile chamber by the low pressure in first volumetric region.At this, can in a different manner the friction part section can be set with resetting, for example by piston piece with respect to the translation back and forth of the wall portion section of mobile chamber or otherwise motion, for example carry out described setting by passing, upwards digging or expand.This friction part section particularly can be arranged on outside the piston piece matrix, for example make by the material of caoutchouc elasticity, this material in first volumetric region low pressure or negative pressure under protuberance or lift flexibly from matrix, and withdrawal or contraction automatically once more abuts on the matrix in case of necessity when low pressure or negative pressure elimination.Under contraction state, for example when piston piece is pushed back its initial position, if in first volumetric region, no longer form low pressure, then the friction part Duan Buyu wall portion section, for example inner walls that move the chamber contacts, and perhaps has not been that braking action ground contacts with wall portion section, for example inner walls of mobile chamber.Advantageously, piston piece move when beginning or leaving the short shift motion of initial position, for example whole shift motion about 10 after bigger low pressure or negative pressure just appear.Utilize low pressure that the friction part section is worked, the film spare of caoutchouc elasticity swells, stably press against on the wall portion section and rub brake piston spare and then braking displaceable furniture parts when piston piece moves thereon thereby for example make.Usually, seal is arranged on piston piece, makes it possible to realize being used in first volumetric region separatedly with second volumetric region low pressure or the negative pressure of buffering course.
Advantageously, described device is designed to, and makes that not occurring pressure in braking procedure in second volumetric region basically raises.Thus, rebound effect or recoil effect on the displaceable furniture parts have been avoided acting on.In device according to the present invention, begin just to brake by the moving movement of friction part section from piston piece, wherein, and be unlike in the known snubber like that on the final subcircuit journey of the moving movement of piston piece to be raise by the pressure in second volumetric region in housing and work, and pressure is elevated to the degree that causes the recoil effect consumingly.According to the present invention, allow the pressure in second volumetric region to raise for above-mentioned reasons and not.
In addition advantageously, described device is designed to, and only allows the pressure in a specified value territory in second volumetric region to raise.May occur in short-term, in second volumetric region by the stress level before the buffering course rise less, for example the favourable shock-absorbing capacity that raises to the snubber that proposed of the pressure in about 0.1 to 0.3 crust scope does not have influence or does not have obviously influence.As the measure that is fit to, can consider the overflow area or the breakthrough part of governor motion for example or control valve and/or respective design, can flow out from second volumetric region in order to when pressure raises, to make air-flow at least.A kind of possible modification be the flexible easily bent of second volumetric region or can when pressure raises, expand also can be automatically reset wall portion, for example form is a rubber sleeve.
In buffer, particularly the residing position of overpressured zone forms second volumetric region in this device, but has the main difference part according to design scheme of the present invention.In contrast, can think that first volumetric region is similar to the negative pressure region of sort buffer device.
Advantageously described device is designed in addition, second volumetric region is under the environment stress at least approx in braking procedure, particularly is under the atmospheric pressure.Therefore, can construct snubber simpler, uncomplicatedly.Only must guarantee in second volumetric region, always can have environment stress or always have atmospheric pressure.Thus, particularly can save the related device that is used to seal the second volumetric region circumference.
The present invention proposes in addition, and described housing is designed to, and outwards the mode with sealing basically limits described first volumetric region.Therefore can guarantee, first volumetric region is formed compare low pressure with second volumetric region of other zone, particularly snubber.Because the high-seal of first volumetric region in all motion stages of piston piece can make this first volumetric region remain in the low pressure range reliably when piston piece moves.For example in first volumetric region, can form the pressure of about 0.1 crust, in second volumetric region, form the pressure or the atmospheric pressure of particularly about 1 crust.Therefore, pressure reduction always about 0.9 clings in this case.
Advantageously be provided with breakthrough part in addition, can in braking procedure, between mobile chamber and exterior zone, carry out the overflow of fluid by described breakthrough part.Undesirable pressure span can be avoided thus, the pressure span of wishing can be realized in other words quicker, enduringly.
Particularly, for example can when will finishing, buffering course avoid high pressure in second volumetric region.Particularly described breakthrough part is responsible for making the pressure in second volumetric region not raise.In principle, can to have outside breakthrough part or this first volumetric region be not positive confinement to first volumetric region yet.At this, only allow considerably less gas exchange, make the almost constant low pressure of maintenance in the volumetric region of winning, this low pressure particularly is in about 0.1 crust and roughly remains on this level in buffering course.But opening but makes and can not produce tangible reaction to the initial drop that arrives about 0.1 crust.
In addition preferably, described breakthrough part is designed to allow from the outside fluid over-flow of second volumetric region.Therefore, in second volumetric region, even when piston piece and/or piston move fast or suddenly, also can avoid in second volumetric region (pressure) to be increased to higher-pressure level rapidly, and then in the motion buffering of furniture parts, avoid associated rebound effect or recoil effect.Particularly when strong on the closing direction/effectively or with HI high impact ground when open position acts on displaceable furniture parts, the quick and/or unexpected motion of piston piece or piston appears.Even described breakthrough part must be designed to also can avoid in this case the disadvantageous pressure in second volumetric region to raise.
The present invention proposes in addition, and described device is designed to, and makes first volumetric region and second volumetric region with separate near airtight mode at least by piston piece.Can in second volumetric region, realize the stress level that almost remains unchanged thus, and can realize externally in first volumetric region, promptly for second volumetric region, be sealed shut.Therefore, can in first volumetric region and second volumetric region, realize different pressure spans reliably and keep this pressure reduction.
In addition, the present invention relates to a kind of furniture with furniture parts movable with respect to stationary body, wherein said furniture comprises said apparatus.Therefore, this family's prodigiosin advantageously is equipped with furniture main body and for example movable door or revolving door, trap, drawer, elongator, carriage or swivel mount.

Fig. 1 and Fig. 2 are illustrated in known snubber under two kinds of different conditions very briefly with sectional view, this snubber have housing and can be in this housing piston that move, that have piston rod,
Fig. 3 and Fig. 4 are illustrated in buffer of the present invention under two kinds of different conditions with sectional view equally very briefly,
Fig. 5 to Fig. 8 is illustrated in other known snubber under two kinds of different conditions with sectional view very briefly, this snubber have housing and can be in this housing piston that move, that have piston rod and
Fig. 9 illustrates another according to buffer of the present invention with sectional view.
The specific embodiment
Fig. 1 and Fig. 2 illustrate a known air buffer or a fluid buffer 1 with sectional view very briefly, and this buffer design becomes the piston rod unit and comprises a column snubber housing 2, and the piston 3 of movable guiding moves back and forth in this snubber housing 2.Particularly tubular piston 3 utilize when in snubber housing 2, moving its week laterally 6 or portion's section wherein on the inwall of snubber housing 2, slide.To fixedly install a piston rod 4 with the concentric mode of cylinder longitudinal axis, this piston rod 4 passes outwards through the opening 5 in the one end side portion of snubber housing 2 on piston 3.This opening 5 is designed to be complementary with the outside of piston rod 4.The motion of displaceable furniture parts (not shown) is associated with the motion of piston rod 4.
The snubber fluid is contained in the enclosure interior 8, for example can be air or other admixture of gas or a kind of pure gas.
At this, the outside 6 of piston 3 has the less cannelure of groove depth 7 (being arranged in the cross section).Piston 3 separates the first volumetric region 8a or the negative pressure region of enclosure interior 8 with the second volumetric region 8b or overpressured zone.Thus, when piston 3 in snubber housing 2 from the position (shown in Figure 1) of almost completely pulling out when move in the position (shown in Figure 2) that enters a lot (deeply) snubber housing 2, promptly in buffering course, although the gas that exists is compressed, still can carry out slight gas overflow from overvoltage side 8b to suction side 8a to a certain extent in volumetric region 8b.
Fig. 3 and Fig. 4 are to illustrate according to air buffer 9 of the present invention with Fig. 1 and the corresponding position of Fig. 2.Air buffer 9 comprises that one has the piston 10 of piston rod 11, and wherein piston 10 can move around in housing 12.Be that with the main distinction according to the fluid buffer of Fig. 1 and Fig. 2 housing 12 has distolateral opening 14, described opening 14 makes the outside opening of the second volumetric region 13b of enclosure interior 13.First volumetric region 13b of enclosure interior 13 and the arrangement shown in Fig. 1 and 2 design accordingly.
Piston 10 from according to the position of Fig. 3 to the buffering course that moves according to the position of Fig. 4, even piston 10 moves towards opening 14 in housing 12 very apace, also can the pressure among the second volumetric region 13b not raise, thereby avoid to piston 10 and then to the recoil effect of the relevant furniture parts that engages with this piston by opening 14.This is because air is enough outwards overflowed from the second volumetric region 13b in large quantities or enough apace.Simultaneously, the negative pressure that in the first volumetric region 13a, obtains almost to remain unchanged, about 0.1 crust for example.In the second volumetric region 13b, set up with housing 12 outside identical pressure, be common environment stress or atmospheric pressure.
At fluid buffer known shown in Fig. 5 to 8 15, wherein Fig. 5 is illustrated in the preceding initial situation of buffering course that utilizes fluid buffer 15.One piston 17 can move in the housing 16 of for example hollow cylindrical of fluid buffer 15 together with the piston rod 18 that is installed on this piston.On piston 17, externally for example have circumferential hoop around piston ring/leather cup 19, this piston ring 19 is particularly made by material flexible, for example caoutchouc elasticity.Piston ring 19 so is fixed on the piston, make piston ring 19 according in the outside or the inboard pressure that acts on the piston ring 19 present corresponding shape, for example outwards expand or protuberance or be pressed towards piston 17.
Be used for last immigration to furniture parts divide the piston motion that stroke cushions before (Fig. 5), the pressure condition of equilibrium establishment particularly in housing 16, wherein piston ring 19 abuts on the piston 17, particularly not with the inwall 16a CONTACT WITH FRICTION of housing 16.In housing 16, there are for example pressure or the atmospheric pressure of 1 crust in other words in piston 17 both sides.
Fig. 6 to Fig. 8 illustrates fluid buffer 15 respectively, wherein piston 17 enters the degree difference in housing 16 in to the braking procedure of displaceable furniture parts, soon state after wherein Fig. 6 is illustrated in moving movement and begins, the final subcircuit journey of the immigration campaign of this and displaceable furniture parts is corresponding.
In Fig. 6, piston 17 only moves into for example several millimeters of housings 16 a little with respect to the position according to Fig. 5.Thus, in housing 16, the volumetric region 20 that is arranged in rear side on the direction of motion of piston 17 has produced for example low pressure or the negative pressure p1 of 0.9 crust.This point realizes by following manner, promptly by volumetric region 20 and the volumetric region 21 that is positioned at piston 17 the place aheads on the direction of motion of piston 17 are separated hermetically.Be moved further (as shown in Figure 7 and Figure 8) by piston 17 along the direction of motion, in volumetric region 20, the pressure of 0.9 crust only drops to the pressure p 2 (according to Fig. 7 and Fig. 8) of for example about 0.85 crust.
In the volumetric region 21 that diminishes in piston 17 the place aheads, under the state according to Fig. 6 and Fig. 7, pressure almost remains unchanged or only lowland is increased in about 1 Palestine and Israel.Only on final subcircuit journey, strong pressure just in volumetric region 21, occurs and raise, for example in 4 Palestine and Israels according to the immigration campaign of Fig. 8.Thus, in known fluid buffer, in the complete make position that arrives displaceable furniture parts not long ago, in according to the inflow location of Fig. 8, triggered a rebound effect according to Fig. 6 to 8.Displaceable furniture parts is travelled forward on the contrary with moving into the direction of motion in short-term, just be drawn into complete make position by for example automatic retracting device in the opposite direction again then.This makes the branch process of the reversing of motion is undesirable.
According to Fig. 6 to Fig. 8, when piston 17 moves in housing 16, the braking action of displaceable furniture parts is realized by the friction between the inwall 16a of the piston ring 19 of outside protuberance and housing 16.
Owing in volumetric region 20, there is the low pressure p1 of about 0.9 crust, piston ring 19 is outwards swelled and is pressed against on the inwall 16a, thereby after the immigration campaign of piston 17 in housing 16 begins, and then begin braking procedure.
Fig. 9 illustrates according to fluid buffer 23 of the present invention, that illustrate very briefly, and this fluid buffer 23 comprises housing 24, the piston 25 that can move at distolateral opening in housing, and this piston 25 has piston rod, piston ring 26 and seal 27.By must having enough large-sized opening 28, on the last highway section of the immigration campaign of piston 25, can not form overvoltage or can not form influential overvoltage at the volumetric region 29 that is arranged in the place ahead, avoided rebound effect thus.And in housing 24, be arranged in the volumetric region 30 at rear, as in according to the fluid buffer 15 of Fig. 5 to 8, after the immigration campaign beginning of piston 25 in housing 24, and then realize a negative pressure, and then making piston ring 26 protuberances, the braking action of fluid buffer 23 or cushioning effect work effectively in constant mode thus.
