Abstract

The drawer (1) of a kitchen cabinet (2) has an electrical supply cable (5) attached to the rear face (10) of the drawer and the rear panel (9) of the cabinet and a three section linkage (7) supports the cable as the drawer is moved.

Description

The invention relates to a kitchen furniture, in particular a wall cabinet, the one in a kitchen unit as a single body with or without shelves can be equipped or can be locked with a door.

Wall cabinets for kitchen units are known from the prior art, which is attached to the wall in the area above a work surface become. Shelfs can be embedded in the wall cupboards to keep dishes or the like on it. Because these wall cabinets the top line above a work surface are special the upper shelves are difficult to access, so that with such Wall cabinets storage space is given, but this space often used only rarely due to its difficult accessibility become. They also offer wall units with shelves often only a storage space for dishes, such as plates, Cups or the like, with an individual special use not considered as storage space, for example for spice containers comes because of the difficult accessibility.

This results in the object of the invention, one Wall cabinet to be further developed in such a way that the shown The disadvantages of the prior art are overcome in that ergonomically better use of the storage space with or without electrification.

This object is achieved in that in the body, preferably arranged on its rear, a vertical thrust is that cooperates with a holding device that the thrust holds in different positions. The integration of a vertical Drawers in a wall cabinet have significant advantages themselves, which can be seen in the fact that, for example, the vertical Storage space available in the drawer directly into the work area the kitchenette can be pulled down so that, for example Utensils for the kitchen are kept in the work area can be. This allows you to always have it ready to hand, as is desired for spices, for example. It is also conceivable for example in this vertical thrust holder for knives or Electrical appliances etc. to accommodate, so when pulling down of the vertical thrust the devices or allowances are immediately within reach Are close. Accordingly, the objects can be made accordingly stow away quickly and are protected from access, such as by children, well secured. There is also the possibility, for example to provide an electrical connection in the drawer, such as for example sockets or lighting, so that when moving out indirect lighting is switched on especially the floor area but also the work area of the Illuminated work surface.

The thrust has guides that are connected to the side walls of the Corpus interact. This results in a vertical guidance Thrust, which prevents the thrust from tilting. In addition, with the guides interact to unlock and lock to an unwanted Prevent the drawer from moving.

According to a particularly advantageous development, for example in the drawer, but also shelves for kitchen items or devices can be arranged around appropriate objects or to keep containers. The holding device can a winding device arranged on a shaft, for example for a cable that winds up or unwinds the cable, to which the drawer is attached with its rear wall. The wave is hollow, with a torsion spring arranged therein which is firmly braced against the body. This results in a controlled, balanced vertical movement over the Cable that interacts with the holding device. The vertical Thrust thus remains in any position or position without it being too an automatic movement comes. The torsion spring is of this type designed to match the thrust counterweight, and a compensating holding device is created which is an unwanted Moving the vertical thrust prevented. Here is the Torsion spring formed from a spiral spring, which is mounted on a shaft is the free end protruding from the hollow shaft on the side wall of the body is set. This results in a fixed operative connection with the fixed part of the body wall against which one End of the torsion spring is supported on the shaft, the other free end of the torsion spring against the weight of the vertical Schubes works.

According to a particularly advantageous embodiment of the invention an electrically operated tubular motor can be arranged in the shaft, which in particular opens up the possibility of, for example, vertical thrust to move electrically. For the electrification of the thrust can in the vertical drawer, for example, sockets for electrical appliances or lamps can be arranged.

According to another embodiment, the holding device consists of a weight that is balanced by a cable pull with the vertical thrust communicates. Such a vertical thrust is characterized by the fact that it is very flat and inexpensive builds, whereby it can also be easily integrated into the single body leaves. For this purpose, the weight is plate-shaped, whereby it is guided behind the bottom of the vertical slide. The weight is increasing thus a narrow space so that the drawer as such is deep can be trained. The flat design of the weight takes thus little space behind the thrust in the single body as such on. Here, the weight on the side walls of the single body guided. To achieve a stable end position both in the inserted State as well as in the extended state of the vertical thrust, it is proposed according to the invention that both the weight in the open position of the thrust as well as the thrust itself in the retracted position together with a snap device acts. Thus, the end positions are secured, so that an unwanted The process of vertical thrust is prevented. there is the cable connecting the weight and the thrust over at least one, arranged on the inside of the insert body Run roller.

According to a particularly advantageous development of the holding device, can this be formed from a toggle joint that with a Gas spring interacts. The gas pressure spring holds the Thrust in the end positions, as well as in a middle position.

According to a particularly advantageous development of the invention a guide is provided for the vertical push, which is in particular Characterized by a on the side wall of the single body definable one-piece shaped guide rail profile in which both the thrust and the plate-shaped weight are guided. Such a guide rail profile, which integrative thrust and plate-shaped weight, allows easy space-saving and effective management of the weight-boost system. This points Guide rail profile in the area of the frame wall of the drawer a guide segment which engages in the frame wall. About the extension the frame wall is a first on the guide rail profile molded on the rear area, especially for the edge area of the plate-shaped weight is maintained.

For additional integration in the guidance system according to the invention also provided that over the extension of the frame wall a second front area is provided for the guide rail profile is in the an intermediate wall to cover the thrust in the body can be snapped into place. Thus, through the guide rail profile Inclusion of the intermediate wall covering the thrust effect. For this In particular, the receiving profile for the intermediate wall has a U-shaped Profiling on, the front leg of the "U's" shorter is designed as the rear, so a simple snap / press the partition is made possible.

In a development of the invention, the guide segment for the Preferably pushed on a U-shaped shape, the rear Area for receiving the edge area of the weight groove-shaped is trained. According to a further advantageous embodiment The invention proposes that the weight be made individually interconnected strip-shaped segments are formed, which are arranged on the cable pull to vary in their number. On The reason for this training is that the vertical thrust is concerned according to its objects to be held by the variability the weight can be balanced. So the possibility exists, in particular to influence the weight in order to to be able to adjust as balanced a weight system as possible. A Another option is to use removable, externally accessible ones Provide weights on the thrust.

An electric cable is proposed for the electrification of the thrust to be placed behind the rear wall of the drawer, which is used for controlled Provision about the displacement of the thrust in the body with a Scissor mechanism works together. As a result of the arrangement of a Scissor mechanism ensures that the drawer is electrifying Electric cable is safely guided and kept available when the Thrust is moved. The cable is thus forced to move Scissor mechanism to be carried out. The cable does not hinder the Displacement of the thrust. For this purpose it is useful Electric cables on the scissor legs forming the scissor mechanism attached. For tight integration in the resulting space between The body rear wall and the rear wall of the drawer are the scissors mechanism on the one hand on the body, preferably on the rear wall of the body, and on the other the drawer rear wall is fixed by means of articulation points. At these joints the scissor legs are articulated accordingly. Includes the scissor mechanism preferably three scissor legs, each are hingedly connected to one another at the ends.

According to a particularly advantageous development of the invention, um a non-disturbing integration of the scissor mechanism between the back wall of the cabinet and to integrate the push rear wall are the scissor legs the length of the species is such that it is retracted of the thrust an aligned position between the rear wall and occupy the back of the body. Thus, the individual scissor legs lie in the retracted state one above the other, so that this also does not affect the volume of the thrust. After an expedient Further development of the invention has at least one scissor leg an elongated hole opening for adjusting a joint. This creates the possibility that the scissor mechanism can be set or designed for different batches.

Figures 1 and 2 show a wall cabinet 1, which is not in one Kitchen unit shown in detail as a single body 2 equipped with shelves can be, the body 2 closed with a door 3 can be. According to the invention, the body 2 is preferably in a vertical thrust 5 is arranged in its rear region 4 cooperates with a holding device 6, which the thrust 5 in different Positions, as is particularly the case in FIGS. 1 and 2 is recognizable, holds. 1 shows one in particular retracted thrust 5, FIG. 2 an extended thrust 5 shows in perspective. The thrust 5 has guides 7, which with the side walls 8 of the body 2 cooperate. This results in for the vertical slide 5 a tilt-free guide in the wall cabinet 1, so that the drawer can be easily retracted or extended 5 is guaranteed.

In the drawer 5 floors or not shown Subjects can be accommodated, which is also considered here, for example Holding devices in this area to provide special Keep kitchen appliances such as knives etc. in this vertical drawer 5 to be able to. As can be seen from FIGS. 4, 5 and 6, there is the holding device 6 is arranged on a shaft 9 Winding device 10 for a cable 11, the winding device 10 winds up or unwinds the cable 11 on which the thrust 5 is attached with its rear wall 12. The thrust 5 is in one channel-like compartment 13 housed, this, through the rear wall 14 of the body 2 and a screen 15 is formed in the body 2.

The shaft 9 is, as from the sectional side view of FIG. 6 recognizable, hollow and includes a torsion spring 16, which is firmly braced against the body 2. As in the cut 6, the torsion spring 16 can be seen a spiral spring 17 which is mounted on two inner shafts, whose free end protrudes from the hollow shaft 9 and on the body rare wall 8 is set. It goes without saying that when the cable 11 is unwound from the holding device 6, the Coil spring 17 is tensioned and a holding effect is achieved prevents the thrust 5 from falling automatically. The hollow shaft 9 is rotatably mounted so that it with the torsion spring 16 or coil spring 17 cooperates.

According to another embodiment, it can also be provided that in the shaft 9 an electric tubular motor, not shown can be arranged, the winding and unwinding of the cable 11th takes place. An additional cable can also be carried with the cable 11 be what the electrification in the thrust 5 allows. For example, sockets for electrical appliances, and connections for lamps in the drawer 5. With regard to the assembly of such a vertical thrust 5, this is the case also designed as a modular structure, so that the entire pre-assembled Unit can be installed in the wall cabinet 1. The screen 15 is designed as a clip-on partition, so that despite the built-in vertical drawer 5 the bar hanger of the body 2 accessible and thus remain adjustable.

Figures 7 to 11 show a further embodiment of the holding device 6. As can be seen from the illustrations, there is Holding device 6 for balancing the vertical thrust 5 from one Weight 18, which is connected to the thrust 5 via a cable 11 stands. It goes without saying that as a result of the interaction the cable 11 when retracting or extending the vertical thrust 5 corresponding to the weight 18 behind the bottom wall 19 of the Thrust 5 is moved. The weight 18 is plate-shaped and guided behind the bottom 19 of the vertical slide 5. how can also be seen from the perspective representation, that is Weight 18 guided on the side walls 8.1 and 8.2 of the single body 2. It can also be seen from the perspective representation that that both the weight 18 in the open position of the thrust 5 also the thrust 5 itself in the retracted position Snap device 20 or 21 cooperates. It works Snap device 20 when the vertical drawer 5 is extended is, the snap device 21 acts when the vertical drawer 5 is retracted. As already stated, it is the weight 18 and the thrust 5 connecting cable 11 via at least one guided on the inside of the single body 2 arranged roller 22, in the embodiment according to the figures a two-roller system is provided, each at the ends of the weight 18 cables 11 are arranged to ensure stable guidance of the vertical thrust 5 or to ensure the weight 18.

Figure 8 shows in the sectional side view how the weight 18 between the vertical thrust 5 and the rear wall 12 of the Single body 2 fits and is guided. In development of the invention a guide 23 is proposed for the vertical thrust 5, the is characterized in that the guide 23 from one to the side walls 8.1 or 8.2 of the single body 2 definable one-piece molded Guide rail profile 24, in which both the thrust 5th and the plate-shaped weight 18 are guided. How the Guide 23 designed as a guide rail profile 24 is in particular shown in Figures 9 and 10, wherein in Figure 9 in the Top view can be seen how the guide rail profile 24 Vertical thrust 5 and the plate-shaped weight 18 picks up.

The guide rail profile 24 has in the area of the frame wall 25 of the thrust 5 on a guide segment 26, which in the frame wall 25 takes hold. The guide segment 26 points for the thrust 5 preferably a U-shaped formation 27. As from Figures 9 and 10 can be seen further, is about the extent of the frame wall 25 a first rear area on the guide rail profile 24 28 integrally formed, the edge areas of the plate-shaped weight 18 records. This area is groove-shaped. It therefore forms a lateral guideway for the weight 18. The guide rail profile 24 is characterized in the invention Further indicate that over the extension of the frame wall 25 on the Guide rail profile 24 formed a second front region 29 in which an intermediate wall 30 can be seen in FIGS. 8 and 9, to cover the drawer 5 can be snapped into the body 2. Profiling for this, it is designed in such a way that the front area 29 has a U-shaped profile 31, in which the front Leg 32 is shorter than the rear leg 33. It now goes without saying, if with the guide rail profile 24 the thrust 5 is integrated in the single body 2, that on simple Way pressed the intermediate wall 30 on the U-shaped profile 31 can be, which is also held automatically in it.

FIG. 11 also shows a perspective view Single body 2, in which a vertical slide 5 is integrated. The special in the embodiment according to FIG. 11 is that the weight 18 from individual interconnected strip-shaped segments 18.1, 18.2 and 18.3 is formed on the cable 11 in their number are variably arranged. Now it goes without saying that an appropriate number can be docked on to this Balance thrust 5 and weight 18, this way the system can be balanced. For fine tuning can, for example, on the upper panel of the drawer 5 an additional Weight 34 to be placed. Another way of FIG. 11a shows fine tuning, with the one accessible from the outside Weights 34 are arranged in the thrust 5.

FIG. 12 shows another embodiment of a top view Thrust 5. The thrust 5 indicates an electrification Electric cable 35 on; which is located behind the rear wall of the drawer. So that the electric cable 35 follows a controlled displacement path, a scissor mechanism 36 interacts with the electric cable 35. In Figure 12, the situation of a partially pulled out Thrust 5 shown. As can be seen from Figure 12, this is Electric cable 35 on the scissor legs 36 forming the scissors mechanism 37.1, 37.2 and 37.3 attached. The scissor mechanism 36 itself is on the one hand on the body 2, preferably on the rear wall of the body 38 and on the other hand on the thrust rear wall 39, by means of articulation points 40.1 and 40.2 attached. These joints 40.1 and 40.2 can be designed as a bearing body. As already stated, Scissor mechanism 36 preferably comprises three scissor legs 37.1, 37.2 and 37.3, each of which is articulated to one another at the ends are.

As can be seen from the top view of FIG. 12, the scissor legs are 37.1, 37.2 and 37.3 the length of the species, see above that when the thrust 5 is retracted it is in alignment a superimposed position between the rear wall 39 with a Take socket 43 and the body rear wall 38. It points in particular the scissor legs 37.1 have a length that is the length of the scissor arm 37.2 covered, the scissor arm 37.2 again has a length that the scissor leg 37.3 in the retracted State of thrust 5 covered. After a particularly advantageous one Further development of the invention, in particular the scissor mechanism 36 as such to adapt to special circumstances, points at least one of the scissor legs, in the present case the scissor legs 37.3, an elongated hole opening 41 for adjusting the joint 42 on. It goes without saying that, for example, the Hinge point 42 in slot opening 41 shifted accordingly can be, so that corresponding changes in length of the scissors mechanism 36 can be made.

FIG. 13 shows in a sectional side view how the scissor mechanism 36 fits into a vertical thrust 5, which with a Holding device 6 cooperates, which consists of a cable 11 guided weight 18 is composed. The scissors mechanism 36 lies then between the weight 18 and the intermediate wall 30, which is in the hanging body 2 is arranged to cover the thrust 5.

FIG. 14 shows the interaction in positions a, b and c of the thrust 5 with a holding device 6, which consists of a toggle joint 44, which cooperates with a gas pressure spring 45. As can be seen from the pictures, there is the toggle mechanism of two rod-shaped elements 46 and 47, the free ends of which are connected on the one hand in a common hinge point 48, wherein on the other hand, one element 46 on the side wall of the body 2 is pivotally mounted, and the other element 47 on the thrust 5. At the common hinge point 48 engages the gas pressure spring 45 with one End, with the other end on the side wall of the body 2. is pivotally mounted.
