Description

Floor element

The present invention relates to a floor element for a kitchen appliance, in particular for a hot drinks machine such as e.g. a fully automatic coffee machine, or for a storage container or a waste container according to the preamble of claim 1.

Kitchen appliances such as fully automatic coffee machines are often set up on the storage surfaces of kitchen units. The service flaps or water or coffee beans container of this fully automatic coffee machine are usually arranged in the rear of the device.

For full access to the service flaps or the water or coffee bean container, the fully automatic machine must be pulled forward and, if the location is unfavorable within the kitchen (niche with wall cabinets), it must also be partially rotated, which, due to the high weight of such fully automatic machines, only takes a large amount Effort is possible.

In order to facilitate access to these service flaps or water or coffee bean containers, as many service flaps as possible or water or coffee bean containers were arranged in the front of the machine in some kitchen appliances. It is also known to equip the kitchen appliances with slide-optimized feet or simple turntables.

The object of the present invention is to provide a base element that ensures easy access to the service flaps or water or coffee bean container with little effort and to further develop such a kitchen appliance or a storage or waste container to the effect that simplified access to the Service flaps or water or coffee bean containers or storage or waste storage is guaranteed with little effort.

This object is achieved by a floor element with the features of claim 1 or by a kitchen appliance with the features of claim 8 and a storage or waste container according to the features of claim 14. The base element according to the invention for a kitchen appliance, in particular for a fully automatic coffee machine, has a base plate and a bearing plate which can be rotated and displaced at the same time relative to the base plate. In facing surfaces of the base plate and the bearing plate, running grooves are formed in which rolling elements held in a rolling element cage are guided.

A slot can be provided in the base plate or the bearing plate, in which a guide element of a fixing device for fixing the bearing plate to the base plate can be guided. The slot can also have an at least partially curved shape, depending on the design of the running grooves and the resulting at least partially superimposed translational and rotational movement.

The running grooves are shaped in such a way that the bearing plate can be rotated translationally and through a rotation angle of a maximum of 160 ° in each case from a basic position in opposite directions of rotation.

With such a base element, it is now possible to realize an optimal travel path for such a kitchen appliance or a storage or waste container. The floor element can be a flat component

be integrated inexpensively in such a kitchen appliance or such a storage or waste container or be attached under such a kitchen appliance or before storage or waste container.

As a result of the possible rotation by a maximum of 160 ° in two opposite directions of rotation from a basic position, service flaps or arranged on the side or rear of a body of the kitchen appliance

Storage for water, coffee beans or the like can be achieved in a simple manner.

Moving (combined translational and rotational movement) of the

Kitchen appliance is made possible by the floor element in a simple manner with little effort.

Advantageous variants of the invention are the subject of the subclaims. According to an advantageous embodiment variant, the angle of rotation in each direction of rotation is between 100 ° and 140 °.

Thanks to the combined movement of the kitchen appliance, which represents the best possible compromise between translation and rotation, the kitchen appliance can be arranged in a niche or corner of a kitchen unit to save space and, if necessary, easily moved. In particular, this also enables easy access to service flaps or memory or control elements arranged on the rear of the kitchen appliance. The proportions of translation and rotation in the overall movement can vary over the course of the movement.

According to an advantageous development, the bearing plate is attached to a tray plate, the tray plate being arranged on the kitchen appliance, for example attached to it.

It is also conceivable to set up the kitchen appliance on the shelf without attaching the shelf to the kitchen appliance.

According to a further advantageous embodiment variant, the tray plate has a recess in which the bearing plate is received. As a result, the floor element can be made even flatter overall.

According to a further embodiment of the base element according to the invention, the grooves of the bearing plate are designed as closed grooves, while a first groove of the base plate is designed as an open and a second groove of the base plate is designed as a closed groove.

As a result, the possibility of movement of the bearing plate relative to the base plate is optimized to the effect that, with a simultaneous translational movement, a rotational movement of at least 100 ° in two opposite directions

Direction of rotation is enabled.

According to a further preferred embodiment variant, the rolling element cage is designed as an axially symmetrical hexagon, that is to say the rolling elements are arranged in an axially symmetrical hexagon.

This ensures that there is always sufficient support to support the center of gravity of the kitchen appliance. The kitchen appliance according to the invention, with a body, a front area and at least one fillable memory in a rear area of the body is characterized by a bottom element arranged on an underside of the kitchen appliance, as described above.

In a preferred embodiment variant, the underside of the kitchen appliance is arranged on a tray plate of the floor element, which enables a kitchen appliance to be retrofitted with such a floor element in a simple manner. Alternatively, the kitchen appliance can be equipped integrally with a tray plate of the base element.

According to an alternative embodiment, the bearing plate of the base element is attached to the underside of the kitchen appliance. Alternatively, the kitchen appliance can be equipped integrally with a bearing plate of the base element.

Alternatively, a floor element according to the invention can also be used in a storage or waste container with at least one reservoir.

Corresponding storage or waste containers are often arranged in corners or in niches in the kitchen or in a piece of furniture, so that rear

Storage is difficult to access.

By using the floor element according to the invention, the storage or waste container can, if necessary, be moved in a combined translatory-rotary manner in such a way that good access to the desired rear store is made possible.

The storage or waste container can be arranged with its underside on a tray plate of the floor element or on a bearing plate of the floor element.

Alternatively, the storage or waste container can also be formed integrally with a storage plate or with a shelf plate of the base element.

Preferred design variants are described below using the

Explained in the accompanying drawings. Show it: Fig. 1 is a schematic perspective exploded view of a

Design variant of a floor element according to the invention

Fig. 2 is a schematic perspective view of a piece of furniture with a kitchen appliance placed thereon with a floor element arranged on its bottom according to FIG. 1 in an initial position,

3 shows an illustration of the furniture element corresponding to FIG. 2 in an advanced position rotated by approx. 120 ° in a first direction of rotation,

4 shows a representation of the furniture element corresponding to FIG. 2 in an advanced position and rotated by approximately 120 ° in a position opposite to the first direction of rotation.

In the following description of the figures, terms such as above, below, left, right, front, rear, etc. relate exclusively to the exemplary representation and position of the base element, body, grooves, base plate, rolling elements and the like selected in the respective figures. These terms are not to be understood in a limiting sense, i.e. These references may change due to different work positions or the mirror-symmetrical design or the like.

In Fig. 1, the reference numeral 2 denotes an embodiment variant of a floor element according to the invention. The base element 2 has at least one base plate 3 and a bearing plate 5 that is simultaneously rotatably and displaceably arranged relative to the base plate 3.

In the embodiment variant shown here, the base element 2 additionally has a shelf plate 4 which has a recess 42 in which the bearing plate 5 can be received. This increases the thickness of the

Floor element 2 overall only slightly.

The tray plate 4 is attached with its upper side 43 facing away from the bearing plate 5 on an underside of a kitchen appliance.

It is also conceivable to set up such a kitchen appliance on the top 43 of the tray plate 4, so that the kitchen appliance is elongated frictionally on the Tray plate 4 stands up and plate 5 is movable relative to the base plate 3 together with the tray plate 4 and the bearing. In this case, the tray plate 4 could have an at least partially upwardly projecting edge or an anti-slip top side 43 in order to securely accommodate the kitchen appliance.

As is also shown in FIG. 1, running grooves 33, 34, 53, 54 are integrally formed in mutually facing surfaces 31, 51 of the base plate 3 and the bearing plate 5. In these grooves 33, 34, 53, 54, rolling elements 61 are guided, which are held in a rolling element cage 6 so as to be secured against loss.

The rolling element cage 6 here has a hexagonal shape, with sides of equal length in pairs, that is to say the rolling elements are arranged in an axially symmetrical hexagon. Depending on the arrangement and design of the running grooves, the rolling element cage 6 could have a different geometric shape and a different number of rolling elements 61.

A slot 32 is provided in the base plate 3, in which a guide element 71 of a fixing device 7 for fixing the bearing plate 5 on the base plate 3 can be guided.

The fixing device 7 has, in addition to the guide element 71, which is designed here as a guide bushing, a bolt 72 which rests on the underside 41 of the shelf plate 4, protrudes through a bore 52 in the bearing plate 5 and on the guide element 71, for example by screwing, is secured.

The running grooves 33, 34, 53, 54 are shaped here in such a way that the bearing plate 5 is translatory in the direction of the slot 32 and by a rotation angle α of a maximum of 160 ° from a basic position, as shown in FIG. 2, into opposite directions Rotation directions, shown in Figures 3 and 4, is rotatable.

The angle of rotation α is preferably limited in each direction of rotation to a maximum angle of rotation of between 100 ° and 140 °. In the embodiment variant shown here, the maximum angle of rotation α in each direction of rotation is preferably approximately 120 °. The grooves 33, 34, 53, 54 are not formed circumferentially, but represent only a partial circle around the to realize maximum permissible rotation angle a. Depending on the size of the pitch circle, the maximum angle of rotation α can be larger or smaller.

To enable the rotational movement while at the same time reliably supporting the center of gravity of the bearing plate 5 and the kitchen appliance standing on the bearing plate 5 or the shelf plate 4, the grooves of the bearing plate 5 are designed as closed grooves, while a first groove 33 of the base plate 3 is open and a second Running groove 34 of the base plate 3 is designed as a closed running groove.

Closed here means that the running groove does not cross an outer edge of the base plate 3.

In the exemplary embodiment it can also be seen that the running grooves 53, 54 of the bearing plate 5 are arranged concentrically or almost concentrically in the bearing plate 5, whereas the running grooves 33, 34 of the base plate 3 from one corner of the base plate to just over half of the base plate 3 protrude.

This arrangement is the best possible compromise between

Translation and rotation achieved, whereby the kitchen appliance can be arranged in a niche or corner of a kitchen unit to save space and can be easily moved if necessary.

This arrangement of the running grooves 33, 34, 53, 54 ensures that the kitchen appliance does not touch any rear wall or side wall of a corner or niche during the entire movement.

Such a bottom element 2 is arranged on a kitchen appliance 9 on the underside of a fully automatic coffee machine.

As can be seen in FIG. 2, the kitchen appliance 9 is set up here on the tray plate 4 of the base element 2. The base plate 3 rests on a worktop 83 of a piece of furniture 8, which is designed here as a kitchen unit. The furniture 8 can be arranged on a wall of a kitchen room.

The worktop 83 is framed on two sides by a rear wall 81 and a side wall 82 which is oriented perpendicular to the worktop 83 and to the rear wall 81. The rear wall 81 or the side wall 82 can also be formed by part of the room wall of the kitchen space. The kitchen appliance 9 is positioned in its starting position in such a way that it is positioned with a side wall close to or close to the side wall 82 of the furniture 8.

As near or close to the side wall 82 of the furniture 8 is understood to be a position of the kitchen appliance in which a mere rotational movement of a kitchen appliance is not round, but rather

For example, a rectangular cross-section would lead to a collision with the side wall while rotating.

The kitchen appliance 9 has a body 91 with a front area 92 and two stores 93 in the lateral rear area of the body 91.

In order to get to this memory 93 of the kitchen appliance 9 in a convenient manner and without much effort, the kitchen appliance 9 is moved by simply pulling it forward in direction A and essentially simultaneously turning it sideways, for example into the position shown in FIG the kitchen appliance 9 was rotated slightly forward and counterclockwise by about 120 ° from its starting position.

4 shows a corresponding representation of the rotated kitchen appliance 9 in the furniture 8 in a position rotated by about 120 ° clockwise, so that now the right memory 93 viewed from the front of the kitchen appliance 9 is easily accessible.

Limiting the maximum angle of rotation a to 160 ° ensures that at least one power cable located on the rear of the kitchen appliance is not pulled out of the socket and that the cable does not block the movement when moving back into the starting position.

As a kitchen appliance within the meaning of the invention, other devices or devices that are used for processing or storing food and / or beverages are used in addition to the hard drinks machines mentioned as preferred.

So the use of such a kitchen appliance in a piece of furniture, in particular a special kitchenette with at least one to a front of the furniture angled, in particular right-angled side wall and a worktop 83 connected to the side wall 82, in which the kitchen appliance 9 is positioned on the worktop 83 near the side wall 82 such that the at least one memory in a rear area of the body is in a basic position is positioned away from the front of the furniture, by attaching or integrating a floor element described above. The at least partially simultaneous translational and rotational movement of the kitchen appliance made possible by this means that a movement from the basic position into a position near the front of the furniture is guaranteed.

Storage or waste containers with at least one storage or waste storage unit also represent a useful application for a floor element according to the invention.

Thus, the use of such a storage or waste container in a piece of furniture, in particular a kitchen unit, with at least one side wall which is angled, in particular at right angles to a front side of the furniture, in which the storage or waste container is positioned near the side wall 82 in such a way that which the at least one storage or waste storage is positioned in a rear area of the body in a basic position away from the front of the furniture, made possible by attaching or integrating a floor element described above. Due to the at least partially simultaneous translational and rotational movement of the storage or waste container made possible, a movement from the basic position into a position near the front of the furniture is guaranteed.
