The containers are respectively selectively closed and opened by a lid (4). Rear walls of freezer containers are arranged one above the other, preferably by common rear wall (7).

Description

A freezer of this type is known as a freezer and is e.g. in Used in the provision of pre-packaged foods, e.g. For Ice cream. A known freezer has e.g. box-shaped, upper side open housing, the removal opening by a cover or more Close arranged side by side cover parts made of transparent material and open. In a known embodiment with a plurality of lid parts these arranged in directly superimposed planes and horizontal Sliding guides either so displaceable that by pushing over one another two lid parts of a portion of the opening of the freezer container free and the underneath befindliches part of the receiving space of the housing is accessible. For removal a food is thus a cover part horizontally over another cover part to move and move after removal back to its closed position.

To a freezer of the present type several demands are made. A Essential requirement is given by the type and quantity of the product, which in to be provided to the freezer. For a product that already has a relatively small amount is sufficient to provide several days, it requires a relatively small pantry, which then at certain intervals to fill. It is also to be considered that the frozen products of of different nature or quality. An essential requirement exists thus ensuring good accessibility to the products. Furthermore it is a present freezer to a series product, the should be inexpensive to produce.

DE-U-1 864035 shows a multi-stage freezer shelf, in which the total of three Steps through laterally insertable night covers in the form of plates are closable. Furthermore, the front walls of each of the steps are each in one acute angle inclined forward, so that at the transition to the slipped night covers a kink results.

The invention is based on the object, a freezer of the initially specified type so that better provision or presentation Frozen products and better accessibility to the frozen products achieved and at the same time the energy requirement is reduced.

The object is solved by the features of the independent claim. The dependent claims form the central idea of the invention in an advantageous manner Continue.

In the embodiment according to the invention a plurality of freezing containers are provided which are arranged stepwise and therefore not only a differentiated provision of Frozen products allow, but also better accessibility to the Ensure freezer containers or frozen products. In the According to the invention, it is thus possible to produce different frozen products provide in separate pantries and it may be the specific Product unerringly be removed from the receiving freezer. In the According design of the invention, therefore, the frozen products are better presenting a good and direct accessibility both to filling the Freezer container as well as for removing the products is achieved. Another advantage the embodiment of the invention is the fact that when using the Freezer less cooling energy is lost, because cooling energy when opening only the the respective freezer container respectively associated lid in only a small extent can escape. The remaining freezer containers remain closed. The inventive design leads taking into account the achievable Capacity also to a space-saving design, since stepped increased Container rooms are used.

The subclaims contain features that govern the provision and the Further improve accessibility, provide an insight into the freezer Improve the opening of the freezer, at a simple and cost effective manufacturable construction guide and information surfaces and direct information of the Make customers aware of the products provided.

Each freezer 2 is a separate lid 4 associated with selectively opening and closing its upper-side opening 4a. Of the Lid 4 is preferably made of transparent material such as glass or plastic. the Freezer is preferably in the bottom area and behind a freezer 5 assigned. In addition, not shown in the freezer containers deep-frozen body arranged by the cooling lines also not shown with the freezer unit 5 are connected, as it is known in freezers per se. The walls of the Freezer 2 are thermally insulated by a thermal insulation 6. It can be a single freezer 5 for the common supply of several each one Freezer container associated with deep-frozen body can be used.

The rearward offset v1, v2 from freezer 2 to freezer 2 and the height H of the uppermost deep-freeze container 3 are taking into account the Body size of an operator so dimensioned that the freezer container of the Operating page 3 ago manually manually accessible and can be viewed. The individual offset measures v1, v2 can be the same or different. this is also valid for the individual heights h1, h2, h3 of the freezer 2. On the back close the Freezer 2 preferably in the vertical from each other, so that the rear walls the freezer 2 arranged one above the other or by a common rear wall. 7 are formed. The front walls of the freezer 2 are 8, the side walls with 9 and the bottom walls labeled 11. In the present embodiment, overlap the upper freezer 2, the respective lower freezer 2 about half. The Volumes of the freezer 2 decrease with their arrangement from bottom to top, so that each lower freezer container 2 has a larger volume than the respective upper freezer containers 2. The individual heights h1, h2, h3 be measured. In the present embodiment, the height h1 is the lowest Frozen container 2 sized larger than the individual heights h2, h3 of the above Freezer 2. According to the reduction of the volumes can also Widths b1, b2, b3 reduce the freezer 2 from bottom to top. The Offsets v1, v2 decrease from front to back. The lengths L of Freezer 2 may be different or the same, as is the embodiment shows.

In the present embodiment, not only a plurality of freezing containers 2 one above the other but also along the operating side 3 arranged side by side, so that horizontally extending rows R1, R2, R3 or steps and upright Rows R4, R5 result. In an arrangement of at least two deep-freeze containers 2 next to each other, the side walls 9 located between each one by a common side wall 9 may be formed.

It is possible to place the freezer 2 on each other and to attach to each other. In the present embodiment, an additional side wall 12 is on each side arranged, whose width to the base width b1 of the lowermost deep-freeze container 2 about is adapted and whose front end side obliquely or convexly rounded inclined backwards is preferably pointed above or leaking at a small top-side face. to Improvement of the appearance, the side walls 12 back and / or bottom side be concavely shaped, in particular circular arc section rounded. The can Side walls 12 with a height h4 be sized larger than the top or the top Freezer 2. By attaching the freezer 2 to the adjacent Side walls 12, the freezer 1 is substantially stabilized in terms of a frame.

If the superposed freezer 2 are of equal length L, The common inner sidewalls can be upright by one Side walls 12 through the middle wall 13 may be formed, said middle wall 13th can form a common middle side wall for the associated freezer 2 or the freezer 2 each with its own inner side walls on the Middle wall 13 may be attached. The middle wall 13 may be connected to the top of the or the uppermost freezer 2 complete or this according to the side walls 12th overtop. The uppermost freezer container 2 has behind its opening 4a Ceiling wall part 4b on.

Between the or the uppermost freezer 2 overhanging end of the Side walls 12 may be one or more juxtaposed Advertising surface carrier 14 be arranged detachably or non-detachably, the front surface 15th preferably complete with the front end face profile of the side walls 12 and can serve as an advertising space 16. As further advertising space 17, 18 are also available the outer surfaces of the front walls 8 and the outer side surfaces of the side walls 9 or 12 on.

The front wall 8 or the lowest freezer 2 or the rest Front walls 8 are or are preferably at an acute angle W with the vertical tilted forward. As a result, in the floor area a space for the feet of Operator created and on the tops of the respective freezer container. 2 larger openings 4a created. Preferably, the front walls are 8 - in the Side view seen - cylinder section convexly curved. The bottom walls 11 are preferably arranged inclined forward. As a result, the accumulate in the Frozen products 2 frozen products due to the inclined bottom surface in The front areas of the freezer 2. Furthermore, there is an improved Product presentation. In at least two adjacent freezer containers may be provided a common, longitudinally continuous front wall 8.
