When design ejecting device, must consider extremely different requirements.Wanting on the one hand can be cheap as far as possible, firmly and save and use spatially ejecting device.Be devoted on the other hand: even particularly when for example must utilize displaceable furniture parts to move very different quality due to variable loading time, also can realize the similar push of displaceable furniture parts.

Summary of the invention

The object of the invention is to, in technology, implement and improve the device that starts described type aspect enforcement economically, and a kind of furniture with related device is provided.

Described object realizes by claim 1 and 4.

Dependent claims has provided the more favourable expansion scheme of the present invention.

The present invention is first from for releasing the device of furniture parts, described furniture parts is movably received on a fixing furniture parts, described device has the push-off pin that an energy drived unit drives, described push-off pin is arranged on one of described two furniture parts, described push-off pin contacts with another furniture parts sometimes to described displaceable furniture parts is released, described push-off pin has contact area, in described contact area, carry out contacting between described push-off pin and another furniture parts, wherein can drive described push-off pin with following object: in the contact lost making during push between described push-off pin and another furniture parts.An importance of the present invention is, contact area has kink/bent angle portion.So just, can design by the contact area on push-off pin or the corresponding shaping by push-off pin realizes the course of desirable push and/or favourable release characteristic.Particularly by relatively simply revising push-off pin, in push, make different effective bar length work thus.Long also the making of different effective bars can be delivered to power and/or the moment difference another furniture parts from push-off pin in push.This point can be advantageous particularly in following situation: for example when push starts, need larger power and/or moment so that displaceable furniture parts can move, particularly in order to overcome the resting position in the closed condition of displaceable furniture parts.Effective bar length of said push-off pin is conclusive, and this effective bar is long relevant to the type of bar geometry and/or kink.Thereby can in the first stage of push, realize with push constantly to compare shorter bar after a while long.By the kink in contact area, when starting, motion also at this kink place, carries out and the contacting of another furniture parts releasing.The mode of release effect that can treat to be conducive to push-off pin the furniture parts of motion is thus adjusted power and/or moment.In addition, utilize the kink in contact area to lay push-off pin in space-saving especially mode.Kink can form a more flat bending angle, for example, deviating from a side of contact area, be 120 to 170 degree or lower.

Another importance of the present invention is, described push-off pin is designed to be out of shape at push Elastic.By be at least push-off pin, particularly the elastic buckling of the part of stand under load in push of contact area can realize: affect push particularly duration and the power that can be transmitted by push-off pin and/or the size of moment.Can make thus the course of push be matched with different conditions, for example, be matched with different quality to be moved when releasing.This point can be realized by the push-off pin of Flexible Design, and reason is described push-off pin according to the intensity of strain and when releasing, correspondingly realizes over time different release effects.According to the size for the treatment of moving mass, the ratio of the servo-actuated distance component not driven after the distance component that can make to be driven finishes from driving effect is different, to obtain all the time roughly the same total release distance.By adjust, the reproducible elasticity wittingly of push-off pin, described elasticity is obvious to the effect of push, can say and can realize according to the different loads of displaceable furniture parts or the release effect of adjusting automatically of other variable boundary condition.

For example the correspondingly configured or location in the dissimilar material properties of the part of the elastic reaction by push-off pin or the strain region by push-off pin, can control characteristic push and elastic relevance push-off pin.

Propose in addition, described push-off pin is designed to, and the maximum position causing by strain in the elastic part end of push-off pin described in push is changed with the length ratio of the elastic part of described push-off pin and be at least 2%, particularly at least 5%.If for example consider that the elastic part of push-off pin is around mounting points flexing, the length of the elastic part of push-off pin can roughly be interpreted as from mounting points to push-off pin elastic part and distance described mounting points end separately.Utilize the strain as above of the flexible portion of having of whole push-off pin or push-off pin section, can realize especially reliably the automatic adjusting to the hope of push, described automatic adjusting and different boundary conditions, quality size for example to be moved are relevant.

More advantageously, described push-off pin is designed to have to the knee/angular pole of kink in described contact area, straight portion's section is at an angle to each other substantially by described kink, to make two of contact area.According to the present invention, " kink " is interpreted as: contact area is not crooked or avoids this trend.By two straight, at an angle to each other portion sections substantially in bending region, can form push-off pin in relatively simple and space-saving mode on the one hand.If desired for space reason, kink can just be formed by straight push-off pin when push starts or when push-off pin swings beginning, for example in the situation that described kink is hinged (formation), described straight push-off pin is particularly straight in enable position.

Utilize kink in releasing motion, accurately to change effective bar long.For example, push-off pin can utilize the kink in contact area in the first stage of push, to provide first effective bar long, and provides another effective bar long in another course of the release campaign of push-off pin.

In addition preferably, described push-off pin has part and the part in push Elastic distortion that is essentially rigidity in push, and the part of described strain particularly comprises described contact area.So just, can make especially simply push-off pin be matched with the release course of different hope.By adjusting part and the part of rigidity substantially of the strain of push-off pin, can be set in push from another furniture parts described in push-off pin is applied to, visibly different power.In addition can realize the Auto-matching of push-off pin in push.The different strain part that for example can also push-off pin be installed on the rigid matrix of push-off pin according to desirable elasticity.These two parts can be members separately or be integrally formed.

Propose in addition, the contact area of push-off pin is designed to repeatedly bend.By repeatedly bending or the polygon shape of contact area, the effective bar that can realize repeatedly prolongation in push along with the bar motion of advancing is long.

Particularly advantageously, the kink in contact area has rigid design, thereby does not change the bending angle being formed by the kink of being correlated with in push.Therefore, push-off pin can be manufactured especially simply and be comparatively stable.

Can person, more advantageously the kink in described contact area is designed to can flexibly change under load.Particularly the kink in contact area can be designed to can flexibly change under load, thereby can in push, change the bending angle being formed by the kink of being correlated with.For example can be by one or more kinks be designed to the change that radial type is realized bending angle.Therefore for example can also in the holding fix before or after push, push-off pin be launched completely, this point be comparatively to save space-efficient.During this external critical load surpassing on push-off pin, push-off pin may be surrendered in crooked place, can prevent from thus damaging.

Another importance of the present invention is, described push-off pin is designed to realize push in the mode of elbow-bar mechanism/toggle mechanism.Utilize elbow-bar mechanism particularly at toggle link angle, very large power can be passed to furniture parts to be moved during for acute angle.In addition, elbow-bar mechanism can be laid to save especially space-efficient mode in extended position.

Particularly advantageously, push-off pin comprises that one is arranged on the toggle link on one of described furniture parts, and described toggle link has arm that can be at an angle to each other in top section, wherein at top section described in push, directly abuts on another furniture parts.So just, can in push, especially effectively power be delivered on described another furniture parts.

In addition more advantageously, for elbow-bar mechanism arranges overcurrent protection structure, that by described overcurrent protection structure, realizes described push-off pin dodges motion/surrender motion, described in dodge the motion reverse movement required with push.When the furniture parts with releasing opposite direction and treat motion carries out the intense mechanical load of unpredictalbe or of short duration appearance, can avoid the damage to elbow-bar mechanism and/or furniture parts.

In addition, the present invention includes a kind of particularly telescopic push-off pin.Thereby can realize, described bar can be driven to move and has relatively turnable scalable portion section.By for example one rotating guide portion or a helicla flute, this helicla flute has the junction surface of extending therein, can realize the flexible of described bar.For example push-off pin can comprise a plurality of cup-shapeds, nested push-off pin element each other, described push-off pin element can be relatively flexible by rotating, and can lay compactly or stretch out.

In addition, the present invention relates to a kind of furniture with displaceable furniture parts, described movable furniture parts is movably received on a fixing furniture parts, and device as above is wherein set.Therefore, for corresponding furniture parts, also can obtain above-mentioned advantage.

For security reasons be necessary that: when starting system mistakenly, do not make the displaceable furniture parts of described system, for example drawer roll away from, and interrupt rolling away from of described drawer when overload.Because this mistake comes from the mistake in control device as a rule, so should not carry out by wrong control device the interference of corresponding secure context.This point realizes thus: described bar two-piece type ground forms, and two parts are connected by cradle head.The torque occurring in cradle head preferably by spring mechanical protect.The advantage of spring is: only must realize momently given elastic force so to change spring profile: make very soft leaf spring profile no longer support surplus torque, and can easily finish cam cycle.If described system runs in original position and passed through top dead centre, spring just can push back two rod members in home position owing to having cancelled elastic load.

In principle, the arrangement proposing advantageously, with the mounting means of displaceable furniture parts on fitment parts independently, ejecting device can be installed generally and/or can easily be reequiped.Particularly needn't provide extra measure so that movable furniture parts is locked in closed position, reason is during displaceable furniture parts can be maintained in its closed position by traditional locking system, for example automatic retracting device (Einzugsautomatik).

Furniture parts is mainly interpreted as the furniture parts for kitchen furniture and house furniture, yet term " furniture parts " can be included in drawer, door and flap/trap on other device, for example drawer on tools cabinet or tool car according to the present invention.

By Figure 24 to 29, elaborate according to optional embodiment of the present invention, ejecting device that there is flexibility bar 34, the perspective view from oblique beneath of flexibility bar shown in it 34, wherein for diagram flexibility bar 34 has concealed the single part of flexibility bar 34 in Figure 25,26 and 29.Flexibility bar 34 comprises two opposed facing

flat housing parts

35a, 35b, and the two is fixed to one another location by connecting pin 36a to 36c.In addition, flexibility bar 34 comprises an elastic bar 37 and a support 15, and described support has rotatably distolateral a roller 15a receiving.Support 15 and roller 15a are for being bearing in flexibility bar 34 on the guide rail of corresponding control element in the mode being for example shown specifically at Figure 10 and 11.

Rod member 37 has the contact site section 37a of a bending on leading section, and described contact site section can be with a matching part section in swing process, for example contact with drawer rear wall.Be positioned on the end on contact site section 37a opposite, rod member 37 extends one section and be received between

housing parts

35a, 35b in the mode of replication to returning.The plate that has bent angle 38 (seeing Figure 25 and 26) at the end upper support support 15 of the replication of rod member 37.If the flexibility bar 34 that can swing in push for example swings around axis of oscillation drivenly, this axis of oscillation for example overlaps with the longitudinal axis of connecting pin 36a, just can form arrangement shown in Figure 27 of flexibility bar 34.At this, rod member 37 under load for example by abutting on drawer rear wall to be released and strain.At this, support 15 is approximately perpendicular to the longitudinal edge of housing parts 35a, 35b.The degree of crook of rod member 37 depends on the power acting on bending direction on rod member 37, depends in other words quality to be moved when releasing displaceable furniture parts.Figure 27 shows the crooked situation of rod member 37 when releasing for example heavier furniture drawer (not shown).

In Figure 28, the overload protection of flexibility bar 34 is activated, and the support 15 being wherein received in swingably between

housing parts

35a and 35b is shown (wegklappen) with respect to the position according to Figure 27.Thus, the effective bearing height being provided by support 15 obviously reduces suddenly, and load on flexibility bar 34 or the effective force on rod member 37 reduce.For example, according in the position of Figure 27, by deflection support 15, make the length of support L1 between the contact-making surface of roller 15a and the imaginary longitudinal axis of

housing parts

35a, 35b be reduced to support height L2.Therefore the power being applied on flexibility bar 34 is reduced.

In order to understand the overload protection according to Figure 28, Figure 29, at rod member shown in blocking 37 and save housing parts 35a in the situation that, is illustrated in the interaction between plate 38 and the folded end of rod member 37.When being exceeded according to the maximum load on the rod member 37 of Figure 27, support 15 by according to the elastic buckling of the replication end of the rod member 37 of Figure 27, rotate (wegknicken) to support 15 according in the overload position of Figure 28 and 29, support 15 is fixed on the replication end of rod member 37 in the mode supporting by the leading section of its plate 38, and wherein said rotation realizes around the rotating support of the longitudinal axis of connecting pin 36c (seeing Figure 24) by support 15.
