Description

The The invention relates to a device housing for a catering kitchen appliance.

such Catering kitchen appliances can both from combinations of single devices as also consist of combinations of individual devices with furniture. From hygienic establish allowed here between the work surfaces the individual devices or furniture no grooves remain. In addition, a must Easy mountability and yet an exact alignment of the objects against each other guaranteed be. This orientation must certainly exist even in the harsh restaurant business stay.

• 1. Über die entstehenden Verbindungsstellen (Stoßstellen) werden Abdeckleisten gelegt und befestigt;
• 2. die Einzelgeräte oder Möbel werden so hergestellt, dass über ihre seitlich aufgestellten Gerätekanten Klemmschienen geschoben werden können;
• 3. die Einzelgeräte/Möbel werden über seitlich angebrachte Bohrungen verschraubt;
• 4. die seitlichen Gerätekanten werden plangenau gefertigt, so dass die Geräte bzw. Möbel über (aufwändige) Verbindungssysteme flächenbündig verpresst werden können.

Usually such devices are connected in practice as follows:

• 1. About the resulting joints (joints) cover strips are placed and fixed;
• 2. The individual devices or furniture are manufactured in such a way that clamping rails can be pushed over their laterally positioned edges;
• 3. The individual units / furniture are screwed on side-mounted holes;
• 4. The lateral edges of the device are manufactured flush, so that the devices or furniture can be pressed flush with (complex) connection systems.

The mentioned options are either unsealed (options 1 and 2) or very expensive (Possibility 4). The device connection can only open when Device operated become (possibilities 3 and 4). There is no uniform compression of the devices on their total depth (possibilities 1-4). In case of repair, disassembly is extremely time-consuming (options 3 and 4). The manufacturing costs are significant (possibility 4).

From the DE 42 28 076 is a device for connecting two adjacent kitchen equipment known, but also very expensive.

Of the Invention is based on the object to show a device housing for a catering kitchen appliance, with a similar device housing in simple Way tight and stable connectable.

These Task is followed by a device housing Claim 1 solved.

Especially the object is achieved by a device housing for a catering kitchen appliance, the side walls includes, adjacent to, similar device housing with the interposition of a Seal are attachable so that working surfaces of the device housing sealed are connectable. There are fastening devices provided for mutual attachment of the devices on a front edge and a rear edge of the work surface. The side walls are in this case so convex or bulged formed that at a Contraction of the device housing means the fastening means the side walls in their middle elastic and compressed closer be considered in the field of fasteners. Through this "bias" is an absolute tight clamping without much effort the clamping devices possible.

Preferably Spacers are provided which the side walls in particular in the middle region between the fastening devices in one Keep a minimum distance from each other. This can not happen that a soft elastic seal in the middle compressed more is considered at the ends. Similarly, it is possible the thus resulting uniform gap to fill with a sealant.

The Distance elements can be designed as separate parts. In a preferred embodiment the spacers are attached to the side walls, so that at the assembly does not have to be respected. Alternatively (or additional) can the spacer elements may be formed in the side walls themselves and, for example, have the shape of ribs or protrusions pushed out of the sheet metal.

The Fasteners can accurately be made so that you can mount the device housing with corresponding force compresses and fastened in the adjusted position. Preferably include However, the fastening devices clamping devices for mutually clamping of two side-by-side housings. Especially easy form such clamping devices when they tabs with konusförmig countersunk holes and screws with complementary shaped heads include. Slide the screws into the holes the cone surfaces on each other, so that a relative movement perpendicular to the screwing between the tabs and the screws is created.

The fastening devices preferably further comprise adjusting elements such that a fastening device, in particular attached to the rear edge, ensures a defined distance between the device housings and the front fastening supply device after an angular collapse of the devices allows the actual adjustment and adjustment of the gap to a constant width.

preferred embodiments The invention will become apparent from the dependent claims.

following become preferred embodiments of the invention explained in more detail with reference to figures. Show here

In The following description will be for the same and the same Parts used the same reference numerals.

As in 1 shown have two device housings 10 . 10 ' side walls 11 . 11 ' on, which should be close together when the case 10 . 10 ' attached to each other. Here, the arrangement should be made such that work surfaces 12 . 12 ' are substantially flush or sealed together.

To achieve such a seal is a seal 20 provided in an appropriate manner between the housing 10 . 10 ' is trapped. It is of course possible in place of a tight seal 20 also inject a permanently elastic seal into the gap.

Furthermore, fasteners 30 . 30 ' on a front edge 13 . 13 ' respectively.

trailing edge 14 . 14 ' the housing 10 . 10 ' provided with which the housing 10 . 10 ' be attached to each other. Preferably, the attachment is in this case such that the fastening devices 30 . 30 ' can be attached to the rear near the upper edge, as in the 2 and 3 is shown. At the front edge are the fasteners 30 . 30 ' preferably from below, under the projecting edge of the work surfaces 12 . 12 ' introduced so that they do not interrupt the daily to be cleaned front surfaces of the housing 10 . 10 ' represent, as in 4 is shown.

The side walls 11 . 11 ' are - as in 6 drawn for better representation because of excessive, bulging outward. They are formed on them or in them distance elements 21 . 22 provided, which are attached to each other housings 10 . 10 ' Make sure that even without an inserted sealing strip 20 a constantly wide gap between the side walls 11 . 11 ' can be ensured (see 5 ). In itself, a single spacer element on each side wall is sufficient. In the embodiment shown here are the spacers 21 . 22 However, formed so complementary that they simultaneously ensure a depth adjustment of the device housing against each other. Furthermore, it is possible to provide a plurality of such spacer elements (distributed over the depth of the housing), resulting in an even more uniform gap between the housings 10 . 10 ' results. Likewise, it is possible the seal 20 at least in its central portions so stiff form that it is no longer compressed by the spherical side walls in the middle as at their ends.

The fastening devices 30 . 30 ' wise, as in 7 shown in more detail, on the one hand tabs 31 on which the case 10 . 10 ' connect together and on the other hand screws 33 . 33 ' , which in tapped holes 35 . 35 ' (please refer 3 ) in the housings 10 . 10 ' can be screwed. The tabs 31 . 31 ' are at least in relation to the front flap together with the associated screws 33 . 33 ' designed as clamping devices. For this purpose, they have enlarged holes with conical flanks 32 or screw heads with a cone-shaped head 34 on, wherein these cone surfaces are formed so complementary that when screwing a screw 33 . 33 ' the cone-shaped flanks 34 / 33 slide on each other and so a shift of the tabs 31 relative to the screws 33 is guaranteed to the housing 10 . 10 ' to move towards each other. In particular, the rear fastening device 30 ' may in this case be designed such that it can be tensioned to a defined end position, which is a distance of the trailing edges of the housing 10 . 10 ' defined to each other, between the maximum and the minimum possible adjustment distance of the front fastening device 30 lies. This ensures that when building a kitchen the actual Adjustment work can always be done from the front.

By the invention shown here various advantages are achieved. In particular, creates a uniform compression by the bias the sealing over the entire device depth. The Preload or compression is retained even if the (or one of the) devices getting hot. The sealing gap is over defines the entire device depth. The fastening of the devices to each other is easily accessible from the front and from the back the connection of the devices can be done together without the need to open the devices. The assembly and the dismantling of the device connection is also in an entire device / furniture line possible. The structure is extremely simple and the production costs are very low.
