Resetting means

Technical field

The present invention relates to a kind of resetting means.

Background technology

The drawer that this resetting means is used for will pushing is on the one hand drawn in the last zone that pushes fully, is used for holding it in like this final position on the other hand, that is, even only under the situation that overcomes less spring force, could drawer be pulled out.

Such resetting means is fixed on first track with its matrix, and said first track links to each other with the main body of furniture usually, and second track is connected on the drawer.Although always need two substantially the same tracks right for drawer and main body are linked to each other, for simplicity below only to a track to describing.

In order to realize the function of resetting means, drivening piece is corresponding sealedly with second orbit-shaped on certain highway section.When pulling the drawer out, certain pull out the highway section after, the shape that the inclination of carrying out owing to the pressure of drivening piece is cancelled between the drivening piece and second track is sealed.Here the power that overcomes an extension spring remains on drivening piece in one latched position; Again engage with the drivening piece entering through moving into drawer until second track, it is derived from latched position also automatically its pulling is got into the final position of immigration through extension spring.

In order structurally to realize this resetting means, known various solution, but these solutions all have significant disadvantages.

For example use such resetting means, this resetting means is positioned at the outside of first track separately, and for example links to each other with first track through a retainer at this moment.But this resetting means is bigger owing to its functional dimension, thereby has limited its availability, and promptly this resetting means can not or be used for less furniture unsatisfactorily.

Another kind of known resetting means specifically is designed to, and matrix is fixed on first track, and therefore in fact resetting means is positioned in the right inner space of track, but drivening piece only is bearing in the guide groove with two guide fingers with longitudinal movement.Said guide finger is because it must less size have corresponding less stability, and this particularly can cause damaging in continuous service, and finally causes fracture and cause resetting means to work thus.

Track with this resetting means is to being mainly used in practicality furniture such as kitchen furniture or the office furniture, and this track is to receiving special load, and known resetting means can not bear this load with the degree of hope.

Summary of the invention

Therefore the objective of the invention is, improve the resetting means of said type like this, lower expending improves its functional reliability and applicability on the structure to utilize.

Said purpose realizes through resetting means according to the present invention; This resetting means is fixed on one and can packs on right first track of track in the furniture; The second right track of said track can move with respect to first track; This resetting means has matrix and the drivening piece that be directed movably by extension spring with loading; This drivening piece is rabbeted with said second orbit-shaped in POF sealedly, the regulation according to the present invention, and said drivening piece can be bearing on the gib block of matrix with the mode of slide block with vertically moving; Said drivening piece has the branch of two side direction, and the spacing that said branch shows the thickness of gib block greatly abuts on the gib block at least in part.

The salient point of the resetting means that constitutes by this form at first is the structure that it is extremely simple, as to save the space, and wherein, the structure of saving the space helps can be with the whole resetting means track centering of packing into without a doubt.Usually first track that is fixed with resetting means or its matrix on it is connected on the main body of furniture.

Being bearing in drivening piece on the gib block according to the present invention by the form of (driving) slide block overlaps said gib block and has basically no and abut in gap on the face that respectively matches in both sides; Thereby can realize accurate guiding, this guiding also makes it possible to achieve bigger carrying.With respect to prior art, realized the load that drivening piece is less generally, this drivening piece helps obviously to improve the service life of resetting means, and this is particularly because foregoing sustained load but particular importance.

According to a favourable improvement project imagination of the present invention; Be fixed on the other hand on the one hand being fixed on matrix extension spring on the drivening piece remain on drivening piece below; Wherein, extension spring being suspended on drivening piece along carrying out in the zone of pull-out direction front portion.Here this suspension roughly on the central height of drivening piece, thus, the spring action that is optimized.

At tension position; When second track broke away from the interlocking with drivening piece, extension spring extended parallel axes ground with track basically, and was loosening and near the final position of loosening; When second track and when also having drawer to be drawn into thus, extension spring extends bendingly.

Another design of the present invention is set; Drivening piece has the slope of the immigration direction rising of an edge second track; The assembling track to the time, promptly when drivening piece is positioned at the final position of spring relaxation, the effect that this slope formation is convenient to install; Thereby the catch element of second track can successfully embed in the drivening piece, the same with situation when remaining in the latched position in the position of drivening piece in tensioned with being tilted.

Catch element moves along said slope when moving into second track, and through said slope, the drivening piece that is made of plastics is distortion like this in this zone, that is, catch element can embed in the clamping recess of drivening piece.

In order to make drivening piece can carry out the distortion transverse to moving direction, drivening piece is designed to continuous opening in the overlay area on slope, wherein downside, promptly continue up to the zone of clamping recess towards the port of extension spring.In the obliquity of said tensioned, gib block passes drivening piece in the zone that is limited on the slope of opening.

Except less power consumption and drivening piece with the fit area of catch element in do not have the distortion that destroys, therefore the configuration of drivening piece upward opening is favourable also, that is, the structure height of drivening piece is minimized.

Gib block and the side that drivening piece matches guarantee that drivening piece is anti-rotational fixing and guarantee that drivening piece is fitted on the matrix securely with matching; Confirm mobile route through a guide groove simultaneously; Said guide groove is arranged in the gib block, and the guide finger that at least one of drivening piece, preferred two front and back distribute in order is directed in said guide groove.The shape of guide groove has determined it in moving direction and also in an inclined direction motion with distributing.

Another kind of design imagination of the present invention; Matrix has a cannelure along the moving direction extension; A kind of centering supplementary structure of the approximate formation of this cannelure; Through this centering supplementary structure, can make with very little gap and accurately locate with respect to second track transverse to the fixing resetting means of longitudinal extension.The branch of one of second track bending moves in the said cannelure when pushing for this reason, and wherein this branch comparatively cooperates accurately and in a subregion, is fitted in the wall portion of cannelure at least.This subregion can form by the protuberance through preferred undercutting, said branch with one be designed to trench guidance tape be bearing on this protuberance, simultaneously, said branch is fitted in the relative wall portion of cannelure on whole or approaching whole length.

Cannelure has an importing inclined-plane in the immigration side, thereby the branch of bending or another set director element can sink in the said cannelure without a doubt.

In order simply matrix to be installed on first guide rail, matrix is provided with socket, and the tongue piece of first guide rail stretches in each said socket, and each said tongue piece is for example crooked after the matrix cover is inserted, thereby it is sealed between the matrix and first track, to form shape.

Other favourable improvement project of the present invention is explained in each dependent claims.

The specific embodiment

At a resetting means shown in each figure; This resetting means representes with Reference numeral 3, and, particularly as Fig. 1 is clearly shown that especially; Can be fixed on one and can pack on right first track 1 of track in the furniture, the second right track 2 of said track can move with respect to first track 1.

Resetting means 3 has a matrix 4, and this matrix shape links to each other with first track 1 sealedly.For this reason, in matrix 4, be provided with socket 13,18 (Fig. 2), the tongue piece 12,14 of first track 1 embeds said socket and deforms in case of necessity, thereby has guaranteed matrix firm connection on first track 1.

One drivening piece, 1 extension spring loads ground and with longitudinal movement, promptly edge second track 2 remains on the matrix 4 with respect to the moving direction of first track 1 movably.For this reason, matrix 4 carries a gib block 6, and drivening piece 5 is bearing on the said gib block by the form of slide block (Reiter) according to the present invention.In other words, drivening piece 5 have two side direction abreast and by the branch that relative to each other erects corresponding to the spacing of the thickness of gib block 6, said branch is fitted on the side that gib block 6 matches in both sides at least partly.

In order to form the spring force that acts on the drivening piece 5, be provided with an extension spring 7, this extension spring is fixed on the suspension pin 9 of drivening piece 5 on the one hand, is fixed on matrix 4 on the other hand dorsad on the end of second track 2

Said suspension pin 9 roughly is arranged on the mid point of the height of drivening piece 5 here, thereby extension spring 7 is stretching, is being to extend axially equably in the position (Fig. 4) of tensioning, and extension spring extends in the position of loosening or loosen basically (Fig. 2) bendingly.Extension spring 7 is placed in the groove 22 of drivening piece 5 in this position, and extension spring also is directed by fixing towards the side thus thus.Stop surface 21 also helps to carry out said guiding, and said stop surface extends to suspension pin 9 from groove 22, as Fig. 1 most clearly illustrates.

In a position of Fig. 1, drivening piece shown in 4 and 5, in this position, second guide rail 2 that for example can be fixed on the drawer is pulled out from first guide rail 1 at least in part.

Can see that in this position, drivening piece 5 tilts with its end regions towards second track 2.For this reason, in gib block, be provided with a recess 20 (Fig. 4), drivening piece 5 is placed in this recess with its end regions of observing in front along pull-out direction.

In other words, in this zone, drivening piece 5 along inclined direction is designed to opening, thereby gib block 6 can sink in the formed opening 11 with its zone that matches.

For drivening piece 5 is directed in this position, on the side of first track, be provided with a guide groove 19 a side and particularly, at least one guide finger that is not shown specifically of drivening piece 5 is directed in this guide groove.When two guide fingers are spaced from each other and are provided with in order, realize mandatory guiding to drivening piece.

Second guide rail 2 is automatically reset in first guide rail 1 that drawer is moved into furniture main body fixed thereon the time with the drawer that links to each other; One is that the edge that two catch element retainings along the form of the projection 25,26 (Fig. 6) of the direction bending of court's first guide rail 1 lean against a card 8 of drivening piece 5 moves in the wall portion of direction back, swings to a shift position until drivening piece 5 from its obliquity.After this, the power effect of extension spring 7 and with drivening piece 5 together with being placed on the catch element 23 in the card 8 and also second track 2 being drawn in the final position position as it be shown in fig. 2 thus.

In order to carry out accurate localization with respect to 2 pairs of resetting means of second guide rail 3, matrix 4 has a cannelure 15, and this cannelure is provided with an inclined-plane 16 along the moving direction extension of second track 2 and in the immigration side, so that the branch that better second guide rail 2 is bent imports.

When second track 2 moves in the cannelure 15, resetting means 3 is accurately located, because this resetting means can be with very little gap transverse to moving into the direction motion.

For the branch of guiding second track 2 bending in cannelure 15 easily, the branch that is designed to trench (Kehle) 24 that wall portion is provided with protuberance 17, the second tracks 2 of a undercutting is bearing on the said protuberance.

Package assembly unit-track right/during resetting means, such situation can appear, drivening piece 5 was positioned in the POF corresponding to Fig. 2 before suit second track 2.Because as stated, catch element 23 only can embed in the drivening piece 5 in obliquity usually, that kind as shown in figs. 1 and 4, thus such problem can appear, that is and, utilize drivening piece 5 to make second track 2 normally in place.

In order easily to realize this point; Drivening piece 5 has a slope 10 along the rising of cover direction interpolation in its side towards second track 2; First projection 25 in the catch element 23 moves on this slope along the cover direction interpolation, so that slope 10 distortion are placed in the card 8 until this projection.Through the intrinsic reset force in drivening piece 5 or slope 10, the wall portion that card 8 correspondingly is out of shape can be out of shape the position of returning the performance function.

In order to make slope 10 distortion, opening 11 to the lower edge towards the direction of extension spring 7 and towards the direction of the dorsal part of card 8 run through/continuous.Form an open slit 27 thus, this slit limits through slope 10 in the outside, and the bottom section through card 8 in extension limits.

Through making in the projection 25 link mouths 8, drivening piece 5 can be dragged in the final position of its inclination when pulling out drawer.When moving into drawer again, catch element 23 is imported into along in the card 8 that moves into the direction opening at it on the whole, thereby when next pulling out drawer again, projection 26 abuts in the wall portion that card 8 matches and drivening piece 5 is correspondingly moved.
