Description

Fridge-freezer with adjustable shelf

Technical field

The present invention relates to fridge-freezer such as refrigerator or refrigerator, relate in particular to the inner room of dividing such freezing and refrigeration by one or more shelf easy to usely.

Background technology

Usually, so realize the adjustable height of such shelf, promptly when forming the inner pressurd vessel of such fridge-freezer, form a plurality of level troughs on the differing heights of inner pressurd vessel sidewall, shelf can move in these grooves.

But the flexibility that the inner room that the solution that obtains of can utilizing over realizes is divided is limited.Therefore, generally can't adjust the obliquity of shelf, but may need such obliquity, especially when being placed on a plurality of identical article on the shelf for taking-up continuously for fast taking-up and filled with product.

Another shortcoming of this known solution is when being placed with article on the shelf, in fact can not revise shelf locations as required.Usually, especially when the user must deposit a large amount of buying food in refrigerator, just such problem has appearred, promptly only fast end of filling process and the position in refrigerator when not enough, find that just the current position of shelf can not place existing cooling article best, the article storage insufficient height of lattice wherein, and the article storage height of adjacent lattice is too high, is therefore rationally used.Will extract one out and be placed with the shelf of article and hang higherly again or lower under such state, this is very difficult, sometimes or even can't accomplish.In most of fridge-freezer structures, in a single day the big inadequately maximum opening angle of door has limited to extract out and has been in the just in time possibility of the shelf of horizontal location, and can extract it out, then exist the danger that the cooling article fall down certainly.Therefore, under this situation, the user is just idle except most of refrigerator of unstowing, and puts into these article or hung shelf again before being reentered into with also will attempting to economize again ground subsequently.

Summary of the invention

Therefore, need a kind of fridge-freezer, it allows to divide more neatly inner room by shelf, and it especially allows to put shelf and/or adjust shelf in the state declivity that is placed with article.

This task is finished by the fridge-freezer with claim 1 feature.Here, the height that the swing property permission of trailing arm is controlled shelf by trailing arm is regulated, and in order to carry out this adjusting, does not need shelf is taken out from fridge-freezer fully.As long as trailing arm can irrespectively swing each other, then they just can realize that various shelves tiltedly put.

According to one first preferred implementing form of the present invention, the trailing arm that can swing and the hitch that can move horizontally are arranged on each edge of shelf.This allows to regulate shelf between two different positions that tilt by making pendulum and the bottom on the trailing arm, and wherein, the hitch that level can be moved limits an axis that is used for the shelf swing.

For example, such structure can realize that shelf a horizontal level and one or propylaeum tilts or backwards or towards the adjusting between the position that the fridge-freezer rear wall tilts forward.Such obliquity of shelf for example can suitably be used to keep flat bottle or jar, and these bottles Bottle ﹠ Can jar always rolls to lower edge on the shelf that tilts, and on this edge, they are removed easily.

In one second preferred implementing form of fridge-freezer, two trailing arms that can swing are arranged, trailing arm and back trailing arm before they are called as on each lateral edges of shelf.Such shelf can be on the resting position of the last resting position of a level, a following resting position and one or two inclination, on this on resting position, second axis extends above the first axle of each trailing arm, on following resting position, second axis extends below the first axle of each trailing arm, on the resting position that tilts, preceding trailing arm lays respectively on the different height with second axis of back trailing arm.In other words, these presumable positions are compared more diversified with first embodiment, and especially can realize controlled parallel the moving of shelf between two highly different horizontal levels.

In one the 3rd preferred implementing form, at least three trailing arms that can swing are arranged on each lateral edges of shelf.Such shelf can only be regulated between horizontal level, and the 3rd trailing arm has been got rid of the possibility that is transposed to obliquity from horizontal level.Therefore, this form of implementation is particularly useful in the problems referred to above that are placed with adjusting height of shelf under the state of article.

If the trailing arm that is placed on the opposed edge of shelf does not interconnect, then there is such possibility, promptly the trailing arm on different lateral edges is brought in the different resting positions and thereby can makes the shelf inclination oblique.Compare with turning forward/recede, the advantage of this flexible program is that the danger that does not exist the cooling article to drop is because the cooling article always by the side wall support of fridge-freezer shell on lower lateral edges.

For the possibility that the skew back that stops shelf is put, these trailing arms can be distinguished connection in pairs.This is suitable to the height that the shelf of article is equipped with in adjusting again.

Especially concerning shelf can before and after the slop regulation, it is suitable that a disabling mechanism that is used to cool off article is installed on the leading edge of shelf and/or back edge, described disabling mechanism has prevented that when carrying out the transition to obliquity the cooling article from falling down.

Although resting position itself is stable under the level of shelf, wherein on this position, second axis normal that links to each other with the shelf ground of each swing arm is positioned at its first axle below, but the antipodal orientation of trailing arm is equivalent to unsettled balance, and shelf is elevated in such orientation.In order to obtain the stable resting position of lifting, suitably make second axis on resting position on each trailing arm than the more close inner room rear wall of this first axle, like this, shelf is supported on the inner room rear wall with its part weight and the position part weight of depositing article thereon.

These trailing arms can be configured to the form of two bending type metallic pins simply, and its first pin is used for embedding a hole of wall, and its second pin is used to embed in the groove of shelf, and a bending connects together them to the pars intermedia of these pins.

Lift on the position for shelf being locked in it, wish to have the locking mechanism of the such trailing arm of at least one locking.But it can be simply tongue piece by resilient movement constitute, this tongue piece has the bearing-surface transverse to tongue piece moving direction ground orientation, it is preferably in that side towards the fridge-freezer rear wall that state lower support that tongue piece do not stress pars intermedia.

Wish in order simply shelf to be installed, open wide downwards for holding the groove that second pin offers thereon.This allows at first trailing arm to be inserted in the hole of sidewall and is projected into the pin of second outside the sidewall before subsequently shelf being placed to and goes up and insert in the groove from the below with second pin.

Preferably the size of these grooves and pin is so fixed, and promptly these pins are snapped in the groove respectively.So just prevented that these pins from can drop out rather than follow the plate motion when plate is raised.

Such card put be very easy to can realize dividually with shelf at one and preferably with on the plastic body of this shelf grafting realize.

The specific embodiment

Fig. 1 represents principle of the present invention in conjunction with the perspective view of the part of shelf 1, sidewall 2 and the rear wall 3 of a fridge-freezer.The insulating foams 6 that inner pressurd vessel that the

wall

2,3 of fridge-freezer is formed by a plastics deep-draw according to traditional approach 4, outer wall 5 and one deck are filled in the gap between inner pressurd vessel 4 and the outer wall 5 constitutes.Inner pressurd vessel 4 is smooth in sidewall 2 zones, except a plurality of blind holes 7 of in the deep-draw process, deep-cutting, in the cutaway view of Fig. 1, only show wherein two blind holes, in other two blind holes, keeping first pin 10 that is used for the trailing arm 8 of shelf 1 respectively swingably.

Each trailing arm 8 has the first horizontal rotation axis A1 that first pin, 10, the first pins that embed in the sidewall blind hole 7 limit trailing arm.One second pin 11 limits the second pivot center A2 parallel with first axle A1, and this second pin is embedded on the shelf 1 according to the mode of describing in detail subsequently.These two pins link to each other by a pars intermedia 12 that is substantially normal to location, described pin ground.These trailing arms 8 can be made by crooked metal round rod simply.

Two unshowned trailing arms 8 remain on shelf 1 on unshowned second sidewall.

Go up in the position shown in the figure 1, trailing arm 8 lax being suspended on floppily in the blind hole 7, the plane that is limited by axis A1, A2 is vertical, shelf 1 is positioned on the stable following horizontal static position.By spurring shelf forward, trailing arm 8 rotations are to the door (not shown in FIG.) of fridge-freezer, and shelf 1 lifts according to this swing.

By living with hand rest and lift the shelf 1 of partly being pulled out, shelf is brought into one second resting position, has been shown in broken lines the shelf on this second resting position in the side view of Fig. 2.On second resting position that also is level, the pars intermedia 12 of trailing arm 8 substantially vertically upward stretches to housing back wall 3 always, but recedes slightly.The effect of this inclination is, shelf 1 equals its weight with one and is put the cooling Item Weight on it a fraction of defeat on the rear wall 3 also thereby also stably be on this resting position of lifting.

In order to prevent to translate in the following resting position under shelf 1 because of carelessness when shaking or spurring shelf 1 slightly, suitably be provided with that being used for that trailing arm 8 is locked in this lifts locational locking mechanism, these locking mechanisms are not shown in Fig. 2, but will describe in detail later on.

Changing over to the process of resting position from following resting position, shelf 1 experienced one in the side view of Fig. 3 with the position shown in the solid line, on this position, pars intermedia 12 horizontal alignments of trailing arm and this two axis A1, A2 are in the horizontal plane.From this position, each trailing arm 8 can not only continue upwards swing, and can continue to lower swing.So, just can adjust the obliquity as in Fig. 3, dotting of shelf 1.

On the position shown in the dotted line of Fig. 3, make respectively towards the back trailing arm 8 of rear wall 3 and reduce, and the preceding trailing arm 8 that faces door lifts.Thereby shelf 1 is towards the rear wall orientated at steep inclinations, lays also relative tilt and being deposited on the rear wall of object thereon.

But, also can adjust shown in the perspective view of Fig. 4, shelf 1 relative fridge-freezer the door 14 orientated at steep inclinations the position.In order to prevent that cooling off article drops out, shelf 1 is equipped with a disabling mechanism 15 that becomes a plurality of vertical panel forms here, these disabling mechanisms of arranging as rake teeth protrude upward from the front genesis of shelf 1, so that keep flat bulge such as bottle Bottle ﹠ Can jar on the shelf 1 that becomes the screen work shape at this.This project organization for example can be used to such fridge-freezer, and promptly it is equipped with the beverage that will sell in Bottle ﹠ Can.For article are placed on the shelf, shelf can be transferred in a horizontal level or the sweptback position, thereby container can cosily be placed on the leading edge.After article were filled shelf, shelf was transferred to obliquity as shown in Figure 4, therefore, when container taking out on shelf 1 leading edge, was positioned at just follow-up of container thereafter, therefore, can comfortablely take out all containers apace in order.

Fig. 5 is the detail view according to the trailing arm 8 and the fixed structure on the shelf thereof of first form of implementation.Pivot center A1, A2 and the pars intermedia 12 second selling 11, limit by these pins that this figure is clear to be shown first pin 10 that inserts in sidewall 2 blind holes 7, link to each other with shelf 1.Shelf 1 here is made of a glass plate 17 basically, it be embedded into one around and the section bar 18 made by metal or hard and force-applied plastics in.As the clearer ground that illustrates of Fig. 1, section bar 18 has two grooves on each lateral edges of shelf 1, but as described in being inserted into by the connector 19 that a kind of plastics of tough and tensile slightly deformed constitute as Delrin in the groove.

Fig. 6 is with the described connector 19 of perspective representation.20, two legs 21 of cover plate of surperficial trough of belt line extend downwards for ease of grasping since one, limit a groove or groove 22 between these legs, and this groove has the cross section of the cross section that is adapted to second pin 11.The size of groove 22 is to determine like this, promptly but second pin 11 is snapped in the groove and frictional rotation, the bottom shrink slightly of groove, thereby really can be from downside 22 li of pin 11 insertion grooves, but when the user lives shelf 1 with hand rest so that shelf is inserted one when lifting the position, this pin can not drop out from groove 22.

In the remote area of its downside, two legs 21 prolong to the next door by tongue piece 23 separately, and described tongue piece clamps the lateral edges of shelf 1 with cover plate 20.

As mentioned above, locking mechanism is applicable to trailing arm 8 is fixed on and lifts on the position.The example of such locking mechanism is described with reference to Fig. 7,8 now.Fig. 7 is the vertical view at the right front angle of shelf 1, is provided with such locking mechanism on its bottom surface.A locking mechanism that becomes mirror image with locking mechanism shown in Figure 7 is arranged on the left-front corner of shelf.

Fig. 8 represents this angle and this locking mechanism with side view.Stretch downwards from 18, one short pins 25 of section bar of the lateral edges that constitutes shelf 1, this pin soft tongue piece 26 at arrow P direction upper support.From pin 25, the part 27, that tongue piece 26 front and back have a lateral edges that is parallel to shelf 1 on its unloading position as shown in Figure 7 stretched to the part 28 of this lateral edges, a lock part and an actuating element 30 that is perpendicular to stop surface 29 forms of this lateral edges with the oblique other places of acute angle.Shown on the position, stop surface 29 has locked the swing of trailing arm 8 on arrow P 2 directions of Fig. 8 and thereby shelf 1 remained on has lifted on the position.If the user wants to reduce shelf, then only slightly actuating element 30 is pressed to a side and promptly in Fig. 7, upwards press and just be enough to make stop surface 29 to break away from trailing arms 8.When shelf 1 lifts, do not need to handle locking mechanism, because trailing arm 8 is oppressed sloping portion 28 automatically from both sides when lifting, go up resting position until arriving, and stop surface 29 is stuck in trailing arm 8 back on position shown in Figure 7.

Because the trailing arm 8 in the opposed side walls 2 of embedding fridge-freezer shell can irrespectively move each other, therefore, the user just can make the trailing arm 8 on a sidewall (being at right side wall among Fig. 9) continue to be lifted away from the position of the shelf 1 shown in the solid line of Fig. 3, on this position, pars intermedia 12 horizontal location of trailing arm 8, and it can make the trailing arm on another sidewall return its low level.So, can adjust in the inclination loxosis of the shelf 1 shown in the side view of Fig. 9 and put.On this position, when having kept flat circular object such as bottle Bottle ﹠ Can jar, just these bottles Bottle ﹠ Can jar can be concentrated on a side of shelf 1.Therefore, the higher free space of shelf 1 can refill article continuously, and take off at that time on the shelf by under container the time, guaranteed this container that is removed be on the shelf standing time the longest and also be the coldest container probably.

If the user has such requirement, promptly wish to stop obliquity, then this can be by paired trailing arm 8 ' realize, as shown in figure 10.Here, a trailing arm of right side wall and an opposed trailing arm of left side wall 2 fuse by a bar that extends below shelf 1, the result, and they can only be elevated or be lowered together.

Single mount arm 8 and the trailing arm 8 that links to each other in pairs ' can be used as accessory to provide so that the user selectively is applied in the fridge-freezer of the present invention, therefore, each user can own decision he whether to utilize loxosis adjustment possibility.

Figure 11 represents the another kind of type of attachment of a trailing arm 8 and shelf 1 according to a sectional view parallel with its lateral edges.If the material of shelf 1 or its framework 18 materials have certain elasticity, then can replace connector 19 with integral type solution shown here, wherein, it is one-body molded on shelf 1 or frame 18 to define the leg 21 of the groove 22 that is used to hold second pin 11.

There is shown another flexible program of the hitch of shelf 1 at Figure 12 to Fig. 2,3 similar side-lookings.The difference of the form of implementation of this flexible program and Fig. 2 only is to be provided with one the 3rd trailing arm 8 on each lateral edges of shelf 1.If the shelf of Figure 12 1 is lifted away from the position shown in the solid line here, trailing arm was swung in different directions from the centre position that trailing arm 8 pars intermedias 12 are in level with the back trailing arm before then the 3rd trailing arm stoped.Therefore got rid of the position that the user adjusts leaning forward of shelf 1 or hypsokinesis accidentally, existed in such position that the cooling article drop or the danger of overturning.Therefore, this flexible program is highly suitable for making in the refrigerator of filled with articles height of shelf to be adapted to actual requirement.

Here, also can allow the user select him whether will utilize loxosis to adjust possibility simply or want to limit such possibility, its way is, on each sidewall of fridge-freezer shell, at least respectively have three blind holes 7 to line up horizontal delegation, and shelf have quantity corresponding grooves 22 on each lateral edges.Whether to two or more outfit trailing arms 8 in these blind holes 7 and the groove 22, he can determine whether feasible obliquity regulates according to the user.

Figure 13 wherein, only has the trailing arm that can swing 8 respectively with the flexible program of a simplification of perspective representation shelf 1 hitch on each lateral edges of shelf 1.Second trailing arm is replaced by the pin 31 of a rigidity, and this pin can move around in a slotted hole 32 that is formed on the fridge-freezer sidewall along arrow P 3 directions.In this form of implementation, by pin 31 supporting and be different towards the height of the shelf portion of the rear wall 3 of fridge-freezer shell, have only front area or between two positions that tilt in different directions, to regulate in the position of the position of a level and an inclination.
