Pull-out device

The invention "relates to a pull-out device, preferably for moving a device, "for example a kitchen device or the like. From a position under a Countertop or the like. in a working position in the area of the plane of the worktop, with one on the worktop fixed fixed part and a movable part.

With pull-out devices of this type, for example in fitted kitchens for pulling out a bread slicer can be used from base cabinets in fitted kitchens, becomes the movable part on which the device in question

is arranged, folded from a position under the worktop into a working position by about 180 °, the movable part is arranged with the device in question in the working position on the worktop. Since that If the device is upside down in its storage position, it must be firmly connected to the movable part. At with a bread slicer provided device, this has the further disadvantage that the resulting during cutting Crumbs fall into the cabinet or under the worktop when the movable part is folded down or in. Therefore, additional collecting containers were installed in lower änken, which is relatively expensive. The folding of the movable part by 180 ° is for example in blenders or the like. practically not possible because there too loose parts are provided. In the case of electrically operated devices, difficulties arise when routing the cables, because the cable connection is facing the user once and facing away once and so the risk of damage of the cable is large. In addition, the connection cable is constantly bent.

There are also known pull-out devices in which the device in question is also in the storage position in a Plane is arranged parallel to the worktop. However, these pull-out devices are only up to one level

609850/0129

liftable, which lies in front of the worktop and which either connects to the underside of the worktop or is flush with the worktop. The disadvantage here is that the pull sine cn an ik be very stable and for their attachment to the worktop a lot of effort must be made, since they have their lever arms must absorb the entire pressure that arises when operating the device in question. -No such a pull-out mechanism is relatively complex and expensive.

It is an object of the present invention to provide a pull-out device of the type mentioned to create the advantages of both known device systems in itself united and with countertops or the like. different thickness can be used.

According to the invention, this object is achieved in that the movable part is held on the stationary part in this way is that, starting from its position under the worktop, it can be pulled out to its front side can be lifted over the worktop, can be lifted into its working position at least partially over the worktop, and rests on it.

The pull-out device according to the invention enables in

Combination translator! See and rotary movements and can be ideally adapted to different worktop thicknesses without any additional adjustment will. It can be advantageous if the movable Part is designed to be lowered onto the worktop. This adaptation is particularly advantageous when the pull-out device according to the invention: ^ at a later date existing worktops should be attached, as the worktops depending on the savings, luxury or old German Execution are of different thicknesses. Since the movable part can be lifted above and onto the worktop can be placed at least partially either directly or indirectly over the device base attached to it, the pull-out and lifting mechanism can be made simpler and less stable, since it only takes up its own weight the movable part and the device concerned must take up during the operation in the working position resulting working pressure is for the most part absorbed by the worktop. The pull-out mechanism can therefore have a simple and light structure. The pull-out device according to the invention is therefore both on the worktop can be placed on top and also always held in planes parallel to the worktop.

A simple design of the mechanics for the extension and lifting movement results when the movable part a carriage guided on the fixed part and one

- 5 -609850/0129

having a carrier pivotally connected to the iagen. This leads the car, which is advantageously provided with clumps that run in parallel guide rails of the fixed part, the pull-out and push-in movement, that is, a purely translational movement, and the carrier performs the lifting movement in the form of a pivoting movement.

Since the movable part only bear the weight of the wearer and the weight of the device placed on it must, it is sufficient if the carrier has at least one preferably fork-shaped intermediate link with the carriage is pivotally connected, which intermediate member is also pivotally attached to the carrier. This is a very simple one and cheap combination of porters and wagons. Are, for example, between A'agen and carrier two arranged parallel to each other fork-shaped intermediate members are provided, so it is advantageous if the pivot axes of the two intermediate members are arranged offset from one another, those of the upper intermediate member facing the worktop facing the worktop. As a result, the carrier can move downwards in relation to a horizontal plane be pivoted much further than is possible upwards without the two intermediate members against each other nudge.

- 6 609850/0129

2524013

The pivot axes can be arranged so that the end positions are each limited by the fact that the two Intermediate links butt against each other, if the intermediate links facing away from the fixed part at right angles Projections of the moving part pivotally attached it is simple and, in terms of the choice of the binding positions, cheaper if at least the projections a stop limiting the pivoting movement is provided, on which one of the intermediate members comes to rest. Such a stop can then optionally also be designed to be adjustable.

For more convenient handling of the movable part when the carrier is pivoted relative to the carriage, it can be favorable if a pre-tensioned tension spring is arranged between the carriage and the carrier. This tension spring is included advantageously arranged so that it is most stretched in the rest position of the wearer, so that it allows the movement supports the carrier in the position above the worktop and brakes its lowering movement.

The carrier can have two side parts on which either the device in question is placed directly or can be attached, or with a support plate

are connected, on which the device in question is then placed. In one case that is in the working position Device with its underside on the worktop and in the other case the support plate, which is then in should advantageously be made as long as possible so that a relatively large contact surface is created. the the latter option is particularly suitable for devices with a smaller area.

The fixed part can either only consist of guide rails that are directly attached to the underside of the relevant Countertop screwable or the like. are, or it can also connect the guide rails and provided with fastening devices provided bracket so that the fixed part forms its own fixed frame. This is especially for the retrospective Attachment of the device according to the invention to a Worktop an advantage.

On the support straps 42 of the side parts 41, the support plate 16 rests on the side parts 41 firmly connects to each other at a constant distance and on which the relevant device 17 can be placed and can optionally be fastened. It goes without saying that instead of the support plate 16, which is preferably made of wood exists, also a connecting strut, band or the like. can be provided that is only as wide as the side part 41. The one provided in the exemplary embodiment

is

Support plate 16 / oblong rectangular. The stop tab 43 of the side part 41 is preferably with a Stop plugs 44 made of plastic.

For the articulated connection of carriage 3I and carrier 32 are two U-shaped, made of sturdy strip material forks 46 and 47 are provided with their parallel to the angle rails 36 of the carriage 31 and the Side parts 41 of the carrier 15 running sides 48, 49 on the projection 38 of the carriage 31 and on the side parts 41 of the carrier 32 can be pivoted, for example by means of rivets forming the pivot axes 5I »52 are attached. The forks 46, 47 lie on the projections 38 from the inside and on the side parts 41 of outside. In the illustrated embodiment are

pins 56 rests and the front edge 61 of the support plate 16 is set back slightly with respect to the front edge 62 of the fixed part. If the movable part 13 is to be moved into its working position, the movable part 13 is pulled out in the seal of the arrow A until the front pair of rollers 33 rests against the stop 23, as shown in ^M ig. 4 is shown. In this first intermediate position shown, the support plate 16 is still arranged parallel to the plate 14 and at the same distance below, which distance depends on the length of the guides 48, 49 of the forks 46, 47 and which corresponds to the height of the device 1? is chosen during manufacture. From this first intermediate position, the carrier 32 is then pivoted upwards about the pivot axes 5I 1 52 of the carriage 3 " ¹ according to arrow B, the pivot axes 51, 52 on the side parts 41 describing the circular path 63" 63 '(FIG. 5 ) «During this circular stroke movement, the forks 46, 47 change their distance from one another without touching one another and the sides 48 of the fork 46 come to rest against the stop pins 56 with an area that lies opposite the previous stop area on the other side of the pivot axis 5I. When pivoting up, the tension spring 57 contracts, so that the lifting movement of the carrier 15 is supported in its second intermediate position shown in FIG then by means of

his carriage 31 pushed back according to arrow G until the ^ -nschlagstopf en 44 of the carrier 15 on the face of the plate 14 comes to rest. The carrier 15 is then lowered as indicated by arrow D until the underside 64 of the support plate 16 of the plate rests with its projecting beyond the side parts 41 on the top area 28, as in ^x ig. 6 shown. The movable part 13 is thus in its working position. If the support plate 16 only rests on the plate 14 to a certain extent, it still cannot tilt when pressure is applied to its side edge facing away from the plate 14, since the side parts 41 with the carriage via the two mutually offset forks 46, 47 31 and are thus non-rotatably connected to the stationary part 12 in this position.

The return movement of the movable part 13 from its working position into its pushed-in rest position takes place in the opposite way. The device 11 is only pushed in and pulled out by a combination of translatory and rotary movements, the planes of the support plate 16 always runs parallel to the plane of the plate 14. The maximum stroke movement from the rest position is such that the movable part with its support plate can be raised to about a few cm above the worktop so that the invention Device for furniture or the like. can be used with tabletops or worktops of almost any thickness.
