Summary of the invention
The objective of the invention is to, improve the synchronism of the track segment of pull-out guide mechanism, this pull-out guide mechanism has at hard-wired guide rail and is installed in the central guide rail between the guide rail that can draw back on the element.
Said purpose realizes through following characteristics: even the control bearing unit comprises deformable, flexible soft rolling bearing body and is out of shape also very little harder rolling bearing body in normal work period; Said soft rolling bearing body is arranged on one with hard rolling bearing body; Wherein the pull-out guide mechanism design becomes; Pushing under the state; Hard rolling bearing body does not receive the power of at least one guide rail in skeleton and the pull out guide rail, makes when said hard rolling bearing body is released, and said soft rolling bearing body can provide reliably synchronously.
Hereinafter provide favourable and suitable improvement project of the present invention.
The present invention is based on a kind of particularly pull-out guide mechanism of drawer of furniture parts that is used to guide, have be used to be installed in the fitment parts for example the skeleton guide rail on the drawer skeleton, be used to be installed in the for example pull out guide rail on the drawer and being installed in movably between skeleton guide rail and the pull out guide rail of the furniture parts that can be drawn out to allow pull out guide rail to draw back the central guide rail that preferably is fully withdrawn significantly with respect to the skeleton guide rail.Be furnished with rolling supporting element between skeleton guide rail and the central guide rail and between pull out guide rail and central guide rail, particularly be installed in ball or roller or roller in the cover.In addition, be arranged between skeleton guide rail and the pull out guide rail acting control bearing unit therefore the motion of central guide rail and pull out guide rail are adapted.
Core of the present invention is; Even the control bearing unit comprises deformable, flexible soft rolling bearing body and is out of shape also very little hard relatively rolling bearing body in normal work period; Wherein the pull-out guide mechanism design becomes; Under the state that pushes of pull-out guide mechanism, only hard rolling bearing body does not receive the power of at least one guide rail in skeleton and the pull out guide rail.
Therefore, can to the motion of central guide rail a kind of " basic controlling " be provided through soft rolling bearing body, reason is that soft rolling bearing body is bonded between skeleton guide rail and the pull out guide rail enduringly.
Preferably, hard rolling bearing body is released with respect to skeleton guide rail and pull out guide rail.
Hard rolling bearing body can absorb big relatively supporting force pulling out between moving period.Yet, through being released, therefore can avoid under the state that pushes of pull-out guide mechanism, particularly for the situation that has high load capacity in the drawer for example, hard rolling bearing body is owing to the power that acts between skeleton guide rail and the pull out guide rail is out of shape.This power is absorbed by all the other supporting members between guide rail.As a result, hard rolling bearing body keeps for example its initial roller shape in very long service time, and the result who follows is that the quality of pulling out operation does not reduce.
The specially suitable supporting mass of control bearing unit is roller or roller.Yet, also can use the spherical bearing body.
The soft underprop roller particularly should be connected to central guide rail with realize desirable central guide rail and pull out guide rail with respect to the skeleton guide rail synchronously.For realizing the favourable control action of soft rolling bearing body, propose in addition, soft rolling bearing body is than the big more than 0.2mm of the passage clear span between skeleton guide rail and the pull out guide rail, and this soft rolling bearing body rolls in this passage.
In a preferred embodiment of the present invention, the control bearing unit is installed on the central guide rail.In this respect, if soft rolling bearing body is arranged on the axle that preferably is fastened on the central guide rail with hard rolling bearing body, then more favourable.Therefore, it is minimum the parts complexity to be reduced to.
Preferably than the big approximately 0.1mm of the passage between skeleton guide rail and the pull out guide rail, this supporting mass rolls in this passage the diameter of hard rolling bearing body.This causes " closely " gapless basically guiding between guide rail.
In another preferred embodiment of the present invention,, on skeleton guide rail and/or pull out guide rail, cut-away is set in order to discharge hard rolling bearing body.Cut-away should be arranged at least one guide rail in the said guide rail, make to be positioned at above or below the hard rolling bearing body pushing under the state portion of cutting, and the result is that the rolling bearing body does not come in contact in this position.
Preferably two cut-away are arranged such that said cut-away is overlapped under the state that pushes of pull-out guide mechanism.Advantageously, hard rolling bearing body then is arranged in this overlapping region, makes it not contact with pull out guide rail with the skeleton guide rail.
In addition, preferably, be used for the bolster horizontal-extending of soft, hard rolling bearing body.The rolling bearing physical efficiency absorbs the gravity of furniture parts to be drawn out effectively like this, firmly.
For realizing improved synchronism between central guide rail and skeleton guide rail or the pull out guide rail; Propose in addition; On at least one guide rail in skeleton guide rail and pull out guide rail, along rolling path formation one surface in the hard still d/d zone of rolling bearing body of soft rolling bearing body, this surperficial tack is greater than other part of rolling path.For example, in this rolling path zone, form one group of tooth, groove or translot or other different rough surface.Also can consider the rubberized different surface.This surface preferably all exists on pull out guide rail and skeleton guide rail.Thereby, can avoid basically pulling out the undesirable biasing of appearance between central guide rail and skeleton guide rail or pull out guide rail between moving period.

The specific embodiment
Accompanying drawing illustrates drawer guide mechanism 1 and comprises skeleton guide rail 2, drawer guideway 3 and central guide rail 4.This drawer guide mechanism 1 is installed on the Furniture frame via installing rack 5 in the and arranged on left and right sides of drawer, and this installing rack 5 is connected with skeleton guide rail 2.Drawer is fixed on the drawer guideway.
Drawer guide mechanism 1 shown in Fig. 1 to 4 is in the state of slightly opening.For being mounted to, drawer guideway 3 can be furnished with supporting cover 6 between drawer guideway 3 and the central guide rail 4 and between skeleton guide rail 2 and central guide rail 4 through central guide rail 4 with respect to 2 displacements of skeleton guide rail.Supporting cover 6 comprises the support column 7 that is rotatably mounted.
Supporting cover 6 is contained in the U-shaped passage 8,9 interior (specifically seeing Fig. 2) of skeleton guide rail 2 or drawer guideway 3 in known manner.Support column 7 rolls along the surfaces opposite to each other of each U-shaped passage 8,9, and the angled part 10,11 of wherein central guide rail 4 is bonded on respectively between the support column 7.
Therefore can realize the gapless relatively each other guiding of guide rail 2,3,4.Usually, only use supporting cover to make that these guide rails are synchronized with each other to remain inadequately fully feasible.
Therefore, be provided with control bearing unit 12.
Here the hard supporting roller 15 that is positioned at the outside for example has an excessive size equally, although significantly less than the excessive size of soft roller, for example than the big 0.1mm of passage clear span a between skeleton guide rail 2 and the drawer guideway 3.As a result, these guide rails additionally relative to each other are supported to a certain extent, thereby " closely " guiding is provided.Hard supporting roller 15 makes it possible at guide rail 2,3, transmits supporting force between 4.
Preferably, as in the exemplary embodiment, axle 13 horizontal alignments of control bearing unit 12.Pulling out between moving period, the soft underprop roller all rolls along each outside 2a, the 3a of skeleton guide rail 2 or drawer guideway 3 with hard supporting roller 15.Therefore, can realize guide rail 2,3, between 4 synchronously.
In this example, skeleton guide rail 2 all is equipped with cut-away 16,17 and band tooth zone 18,19 with drawer guideway 3.Band tooth zone only is positioned at respectively on each travel path of the soft underprop roller on skeleton guide rail 2 or the drawer guideway 3, and cut-away only is formed on each travel path of the hard roller 15 on skeleton guide rail 2 or the drawer guideway 3.In addition, each is with tooth zone 18,19 and each cut-away 16,17 all to be attached to like this on skeleton guide rail 2 or the drawer guideway 3, makes and when drawer guide mechanism 1 is in the state that is pushed away together, sees that from vertical direction they are overlapped.This has guaranteed; When drawer guide mechanism 1 is pushed away together; Promptly when drawer be pushed into, just in time before reaching the final position; Hard roller 15 " entering vacant state ", thus be released through cut-away 16,17, and this cut- away 16,17 is wideer than hard supporting roller 15 itself to a certain extent.Yet in this zone, the pull(ing) effect of hard supporting roller 15 disappears.But, in this zone, obtain especially guide rail 2,3,4 relative to each other synchronously reliably, make the travel zone of soft underprop roller 14 be arranged to be with tooth, thereby make soft underprop roller 14 can not slip over.
In this example embodiment, in the position (in this respect, particularly referring to see-through view) that respectively originates in each cut-away 16,17 appearance on the travel path of hard supporting roller 15 on the travel path of soft underprop roller 14 according to Fig. 5 with tooth zone 18,19.
In Fig. 1,2,3 and 4, each supporting roller 14,15 is no show band tooth zone 18,19 or cut-away 16,17 still.
In Fig. 5, on the contrary, supporting roller 14,15 has been arranged in said each zone, although still no show drawer guide mechanism 1 finally pushes the position completely.Yet even visible hard supporting roller 15 is " released ", the soft underprop roller also can provide reliably synchronously up to drawer guide mechanism 1 through rolling and inserted fully along the tooth zone 18,19 of respectively being with on the outside 3a of skeleton guide rail 2 or the 2a.
In addition, soft underprop roller 14 guarantees that from cut-away 16,17 translations the time, hard supporting roller 15 is lifted on each travel path on skeleton guide rail 2 or the drawer guideway 3, and each guide rail is by relative to each other guiding reliably simultaneously.Here the length dimension of preferred cut- away 16,17 is designed to make that hard supporting roller 15 is not on each travel path that is lifted to simultaneously on the skeleton guide rail 2 and on the drawer guideway 3.This is shown in Fig. 5.Visible by this figure, hard supporting roller 15 is just being mentioned on the travel path of skeleton guide rail 2, but still is arranged in the cut-away 17 of drawer guideway 3.So alternately hard supporting roller 15 is lifted to the homogeneous as much as possible that moves of pulling out of having guaranteed drawer guide mechanism 1 on each travel path.
Because hard supporting roller 15 is released, avoided under the state that pushes of pull-out guide mechanism, exposing " upright plate " at hard roller place.
