The specific embodiment

In Fig. 1 to 7, the element with identical function and operator scheme is represented by identical Reference numeral respectively.

Fig. 1 shows the part of the refrigerator doors 1 of domestic refrigerator, and this door utilizes the deep-drawn method to be formed by plastics.Side direction ground forms one first guide rail 2 is arranged on the left hand edge zone of this refrigerator doors 1; This first guide rail vertically extends along the y direction or along short transverse; Also promptly extend, this first guide rail is along x direction, promptly outstanding on the contrary or stretch out along the smooth inwall of orthogonal direction or depth direction and door 1 from top to bottom.In a similar fashion, second guide rail the right hand edge zone of door in arranges apart from ground that apart from first guide rail, one predeterminated level this second guide rail is positioned at the outside of the partial sectional view of Fig. 1 at this.In with respect to the rectangular section plane of short transverse y, see over, a door guide rail 2 is L shaped shape, and is extended with a guide ribs 3, wherein the inwall of this guide ribs and refrigerator doors 1 extend abreast, along z direction or horizontal expansion, be moulded equally.In this illustrative examples, guide ribs 3 with respect to 2 one-tenth one right angles of door guide rail or 90 ° of angles extend in the space between door two guide rails of 1.This guide ribs is extended in the plane of orientation of y, z direction basically, also promptly this plane of orientation parallel with door 1 smooth inwall and with its apart from the depth distance that can limit.

Yet the form of this guide ribs is not what limit, and for example it can be wedge angle or fillet.The wedge angle of guide ribs 3 or the outline of fillet are easy to discharge in the situation of deep-drawn.The additionally easy to clean and shape of the shape of fillet is pleasant more.In door guide rail 2, form two and hold element, for holding groove 4, they are used for the adjustable for height mounting support of door bracket 5 in this embodiment.In essence, also can relate at this and to hold protuberance, but this will limit the space that is used for door bracket 5 a little.On the sidewall 6 of door bracket 5, door bracket 5 has flexible member 7, wherein on the end that can freely be shifted of said flexible member 7, carries and holds protuberance 8, and this holds protuberance 8 quilt in this view and hides and join in one that holds in the groove 4.By means of holding groove 4 and holding being bonded with each other of protuberance 8, (along y direction vertical) of door bracket 5 on door bracket 2 highly is fixed.On the opposite side (not shown) of refrigerator doors 1; Axially another second guide rail of symmetric construction is positioned at two guide rails with respect to the central axis of receiving area, and the same axial symmetrically arranged flexible member that is positioned on second sidewall of door bracket 5 joins said receiving area in a similar fashion to.

With hold groove 4 and hold the sidewall 6 that extends along depth direction x that the flexible member 7 that is connected is connected to door bracket 5.In this illustrative examples (and equally in other is retrofited subsequently), flexible member 7 is parts of the one of sidewall 6, and wherein, the end back, that can freely be shifted of flexible member 7 is cut out from its plastics in sidewall 6.On the front end of flexible member, flexible member is connected to, just molded and shaped to this sidewall.Certainly, according to favourable optional example, flexible member if necessary can also be provided with the mode of putting upside down, and that is to say that the rear end of flexible member can be hinged, and the front end of flexible member can be shifted freely.Flexible member preferably is set to the sheet spring.This flexible member especially evenly is integrated in the sidewall basically.This flexible member is set to a beam element, and it has the qualification profile of essentially rectangular.This flexible member is arranged to the upper and lower lateral edge of said flexible member and is extended abreast along the top edge and the lower limb of depth direction x and sidewall basically.In this case, flexible member can with respect to along the y direction, be vertically extending axis of bending with respect to the plane of orientation of the x of sidewall, y laterally, displacement especially vertically.If pressure is applied on the flexible member 7; Then the protuberance 8 that holds on the end that can freely be shifted of flexible member moves to the inside of door bracket from holding groove 4 after z direction lateral displacement at it, and discharges door bracket 5 so that realize the purpose of height adjustment.The finger that external stress on the flexible member 7 can be pressed into through user's the outside from sidewall 6 on the zone that can freely be shifted of flexible member 7 is applied in or is applied in through the release slope 9 that holds setting groove 4 at each.As long as door bracket 5 upwards, promptly move along the y direction, then discharges slope 9 via these, hold protuberance 8 along the z direction, promptly with respect to the plane of orientation of the sidewall 6 of door bracket 5 from the outside inside sidesway.Be released from holding groove 4 as long as hold protuberance 8, then door bracket 5 can up or down, promptly move to along the y direction respectively and hold groove 4.By means of the slope that go up to discharge that holds groove of correspondence, only guaranteed through raising corresponding door bracket, flexible member be moved laterally in the sidewall of door bracket or sidesway in the inside of door bracket and automatically empty path upwards.The hand pressure that on flexible member, applies through the operator thereby be unnecessary.In this case,, realized upward displacement the free-running operation of door bracket when moving.On the contrary; In the d/d situation of door bracket; Also promptly when upwards the promotion motion is stopped; Door bracket thus be fixed on immediately next hold in the groove down, promptly being arrested holds in the groove under the next one, utilize the plane of orientation wedging or imbed below this release slope that holds groove, thereby one of them of door bracket holds protuberance so that the downward motion of door bracket is automatically stopped.If only be arranged on two lateral elasticity elements hold protuberance by the operator be pressed on one's own initiative door bracket inside and thereby shift out from holding groove, then door bracket can be detained the position from this and is released with further displacement downwards.

In the process that moves, 3 slips in the sidewall 6 of door bracket 5 along the vertically extending guide recess 10 of short transverse y along guide ribs.Two side cheeks of guide recess or the guiding groove 10 of the guide ribs 3 of corresponding door guide rail 2 through the sidewall 6 of door bracket 5 are by fastening or besieged.Vertical guide groove 10 is formed at this step through rectangular depression in the sidewall 6 with integrally formed flexible member 7 or inwardly formation.If door bracket 5 thus at its horizontal level through guide ribs 3 and feasible inwall through refrigerator doors 1 by stable, thereby prevented tumbling of door bracket 5.Guide ribs 3 also prevent door bracket completely, the taking-up do not expected, withdraw from door bracket along the x direction from plane of orientation x, z between two guide rails if attempt.Guide ribs 3 or door guide rail 2 can be along the whole height placement of refrigerator doors 1, thereby extend in the y direction along whole refrigerator doors 1.In this case, the taking-up of door bracket 5 only can be on refrigerator doors or lower end realize.In order to ensure the feasibility of repeatedly taking out, door guide rail 2 or only guide ribs 3 can be disconnected to the section of one-tenth.Door bracket 5 is preferably formed by transparent plastic.Yet door bracket can have opaque or colouring or that material is different with the remainder of door bracket 5 other plastic components in the zone at flexible member 7 places.In the situation that first of molded and shaped guide rail is retrofited, do not relate to assembly working.

The various embodiment of refrigerator doors 1 (in the situation of the adjustable for height catch mechanism of door bracket 5) is especially distinguished part now and is that side direction door guide rail 2 is provided with guide ribs 3 and the mode that holds groove 4.In this stage, what it might also be mentioned is that holding groove 4 can be set up or be formed with various mode.Hold groove and can be set to rectangle, but can also be set to circle or ellipse.As shown in Figure 2, saidly hold the part that groove can be the band that stretches out along the x direction from door guide rail 2, but can also as shown in Figure 1ly be incorporated in the side cheek of guide rail.Depend on design requirement and the manufacturing approach that is adopted, can expect the various remodeling of a guide rail 2 at this.In illustrative examples remodeling as illustrated in fig. 1 and 2, guide rail, guide ribs and catch mechanism and refrigerator doors form.Refrigerator doors utilizes the deep-drawn method to be made substantially, thereby in the situation of this integral type embodiment, the door guide rail 2 with guide ribs 3 and catch mechanism 4 is simultaneously by drawing.This is a kind of special saving cost techniques scheme, and wherein, the assembly working that need not to add is so that realize the height adjustment of door bracket 5.For this purpose, thermoplastic is introduced in the special respectively instrument of making substantially, and comprises that the whole refrigerator doors 1 of guide rail 2 is made in a procedure of processing on the whole.The shortcoming of this embodiment is, the various breech lock step of catch mechanism 4 or to the door guide rail 2 of the different designs of dissimilar refrigerators or guide ribs 3 will be respectively need be to the independent instrument of the whole refrigerator doors 1 of every kind of desired type.

In order between dissimilar refrigerators, to have more how different possibilities; But can when deep-drawn electric refrigerator door 1, adopt the least possible instrument simultaneously; So according to the favourable remodeling of Fig. 3 a, 3b, only the matrix 10 of door guide rail 2 and can in the whole height of door, extend continuously along the y direction or only become that section ground extends hold guide rail 11 and the electric refrigerator door integrally formed.On the other hand, in this illustrative examples, guide ribs 3 is made as independent parts, and is installed in forwardly on the guide rail 2 subsequently.Said guide ribs can be by forming with the matrix 10 identical or similar plastics of door guide rail 2.Yet, for example can form said guide ribs, thereby give more luxurious outward appearance for electric refrigerator by metal or other high-quality material.Guide ribs 3 can only cover the forefoot area of the matrix 10 of door guide rail 2 shown in Fig. 3 a, can give expression to specially designed impression thereby only watch from the place ahead.Yet shown in Fig. 3 b, said guide ribs can also be extended on the wide zone attached to the outside of the matrix 10 of guide rail or outside cheek continuously.In situation the most widely, shown in Fig. 3 b, said guide ribs can be extended the surface until electric refrigerator door 1.Said guide ribs thereby fully coat the front of guide rail basically and the outside cheek of guide rail.Especially, guide rail is held through the mode of guide ribs 3 with U-shaped; Whole door guide rail 2 thereby be affected through outward appearance by guide ribs 3 visual expression.In addition, the guide ribs 3 of 3 sidepieces of the matrix 10 of the clamping door guide rail 2 among Fig. 3 b provides bigger contact surface for the matrix 10 of door guide rail 2, and thereby allows on the door guide rail more fixing.If guide ribs 3 utilizes adhesive to be connected to matrix 10, then this is particularly advantageous.Yet, equally advantageously, different connections, for example hold or be threaded between these two parts, producing.Substantially, guide ribs 3 is configured to independent parts and compensation is provided because the possibility of the error that manufacturing caused of refrigerator doors 1.Guiding split-hair, contour limit to door bracket 5 can realize.In the situation of the deep-drawn method that is used for making refrigerator doors 1, in fact can not utilize such precision to carry out work, promptly guide rail 2 is always sat idly on same position on refrigerator doors 1 clock like precision.Especially, the difference of parallel each other guiding to them can occur.Firmly be clipped between the guide rail 2 that connects on every side for fear of door bracket 5, these guide rails a little further outwards move than most applications for reasons of safety.Thereby in the situation of the guide rail 2 that one is made, guide rail strip 3 does not accurately have minimized distance ground from door bracket 5 and extends.Yet; If guide ribs 3 is being installed on the refrigerator doors 1 or on the molded and shaped matrix 10 at first guide rail 2 subsequently; Then guide ribs can with respect to door bracket 5 or with respect to the guide ribs of on the opposition side of refrigerator doors 1, arranging of second door bracket 3 by location very accurately, thereby between the guide ribs of arranging abreast and each other of two guide rails, caused guiding to point-device, the form fit of door bracket 5 apart from the horizontal range ground that limits.

Fig. 4 shows another the favourable illustrative examples to the adjustable for height mounting support spare of the present invention of door bracket 5.In the situation of this illustrative examples, only the matrix 10 of refrigerator body 1 and door guide rail 2 preferably utilizes the deep-drawn method to be made into integration.At this, matrix 10 perhaps is moulded by drawing.Said matrix 10 stretches out along the smooth inwall of x direction with door 1 as a kind of bar of cylindricality on the contrary.When in x, z-plane, watching, said matrix has the geometry of substantial rectangular.The matrix 10 that the very big work relevant with technical instrument is formed that need not by means of door guide rail 2; A kind of basis good, that practice thrift cost is provided; Especially a molded and shaped post; The one or more additional parts of the mounting support spare of the door bracket 5 that is used to realize height adjustment can be installed on said post, and they can be suitable for dissimilar electric refrigerators respectively with simple mode.In order aspect functional and at design aspect, the free degree of the maximum that produces catch mechanism and guiding piece to be provided, guide ribs 3 with hold guide rail 11 and hold groove 4 as independent parts, promptly made as common means.Guide ribs 3 with hold guide rail 11 thereby formed one adaptive 12 together, its preferred one is made.Yet said adaptive can also comprise a plurality of elements, thereby for example the stainless steel strip of attractive design etc. can be connected to the surface that deviates from refrigerator doors 1 of guide ribs 3, so that realize the design to the correspondence of more luxurious model of refrigerator.In the situation of the refrigerator of low-cost type, on the other hand, adaptive 12 can be used as the simple injection profiled part and is processed integratedly.Yet the particularly advantageous aspect of this embodiment is, the refrigerator doors 1 with molded and shaped matrix 10 always can likewise be made with the mode of practicing thrift cost, and this type with electric refrigerator has nothing to do.Realized the characteristic design by means of applied adaptive.In a preferred embodiment, adaptive the shape that can be bent to U-shaped, and thereby preferably encirclement or fastening, just around the whole substrate of guide rail, this makes only through adaptive definite whole design on the other hand.On the other hand, sealing of adaptive U-shaped realized adaptive stable especially being connected with matrix.This connection can be implemented by means of adhesive, screw thread or other known technique for fixing.In a preferred embodiment; This is guaranteed by means of holding connection, wherein saidly holds connection by means of the joint that holds element that is preferably placed at the complementation corresponding, that be provided with on the holding element and they and being positioned at matrix 10 on adaptive 12 the rear portion that holds guide rail 11 and realize.This is can find out in the sketch map at Fig. 5.

In a word, equally advantageously the guide rail of correspondence is provided with and is positioned at anterior at least one adaptive.The door of this adaptive coating guide rail when opening towards user's front.Additionally or independently, adaptive can be partly or integrally cover outer, the lateral side cheek of corresponding guide rail, and it preferably with respect to the smooth basically inwall of electric refrigerator door laterally, especially vertically extend.If necessary, adaptive can also be partly or integrally surround interior, the lateral side cheek of corresponding guide rail, and it preferably with respect to the smooth basically inwall of electric refrigerator door laterally, especially vertically extend.In the rectangular horizontal section plane of plane of orientation with respect to the inwall of door, see over, in the preferred variant adaptive preferably with the form setting of U-shaped, thereby its surrounds all three sidepieces of corresponding guide rail.

On the one hand, realized interspersing or the function of lace element for adaptive.On the other hand, adaptive additionally or independently be used to compensate with two guide rails between the relevant any foozle of lateral separation that surpasses their height.Especially, adaptive on the guide rail of correspondence also is used as the induction element that is used for adjustable for height door storage container.As the element of setting up on the guide rail of correspondence, said adaptive allows guiding with irrelevant accurate horizontal location and the accurate side direction of its foozle of door bracket.

Especially, utilize this to set up element, the lateral separation of the expectation in the gap between two vertically extending guide rails can be kept in its whole height with the mode that limits.Corresponding door bracket thereby when upward displacement, between two guide rails, guided no problemly, thus the height and position of door bracket changed, and tilt or not holding of edge can occur.For the side direction guiding of door bracket, adaptive on the corresponding guide rail preferably additionally has the post bar, and its direction along the inwall that is disposed of door bracket is stretched out, and thereby is bonded in guide groove, groove or the protuberance of the correspondence that forms with complimentary fashion.Certainly, groove and post bar also can replace at door bracket and guide rail, especially be provided with on its adaptive.

In a particular case, advantageously, corresponding adaptive additionally has the utensil of holding, and this holds the element that holds that utensil is used for detaining in a plurality of differing heights position the complementation of being disposed on the door bracket.These hold utensil and are preferably placed on adaptive the inboard cheek on the corresponding guide rail, thereby they can interact with the element that holds that on the lateral side wall of door bracket, is provided with.

Taking it by and large, in this case, adaptive except interspersing or structural detail and also having the side direction guiding function as being integrally formed as the function of detaining or holding utensil of discrete component.

Adaptive thereby realized satisfying variedly different structure and requirement attractive in appearance for same door type (its two door guide rails always have identical design or geometric format and structure).Especially; Allow the door of same fundamental type in all situations, to be used for dissimilar household refrigerating appliances; Can realize the personalized design of door by means of adaptive of correspondence, it is specially to the design of the expectation of particular home electrical appliance type and Structural Engineering standard.

In a word, adaptive thereby realized the low-complexity of household refrigerating appliance door, the structure of cost savings.By means of this adaptive, can be so that no problem the holding, guide and/or hold in the free space of adjustable for height door bracket between the guide rail of two horizontal intervals of electric refrigerator door.Especially, if necessary, by means of adaptive the high accuracy that also can guarantee the side direction guiding of door bracket.The upgrading subsequently, the part of guide rail also is feasible.
