    专利说明:

    Generally the present invention relates to shelf structures. In particular, the present invention pertains to shelf structures for cold storage cabinets.
    BACKGROUND
    There are different stages during a baking process and bakery cabinets are used for varying needs during the different stages. The dough needs to be in various specific temperatures during the baking process for optimal baking products.
    However, cold storage cabinets such as bakery cabinets, refrigerators and freezers face some problems today.
    Baking trays (or baking sheets) tend to have national standards. However, the standards vary between countries. Therefore, the width and/or size of the baking 20 tray vary in different countries. This creates problems for cold storage manufacturers as they need to produce cold storage cabinets in several sizes.
    Attempts have been made to solve the problem of varying sized baking trays. In figure 4 is illustrated a front view of a prior art cold storage cabinet 450 where 25 vertical steel frames 452 has been placed on both sides inside the cabinet. Holding plates 454 are attached to the frames so that the holding plates extend from both sides of the cabinet. The holding plates may be for example 10 cm wide allowing the use of varying sized trays. However this construction has some drawbacks.
    Firstly, the construction is unstable, which provides some challenges in a fast working environment where baking trays are inserted and taken out continually. Secondly, it is challenging to clean the construction. All the parts need to be removed and separated for proper cleaning. Still, the steel frames comprise forms 35 and slots that are difficult to clean completely. The steel frames comprise fastening holes for the holding plates that are difficult to clean properly.

    DETAILED DESCRIPTION OF THE EMBODIMENTS
    Referring to figures 1 and 2, the shelf structure 100 comprises a first and second body part 102, 104. The two body parts are substantially parallel. The body parts 20 form the front and the back side of the shelf structure 100. For example the first body part 102 may be inserted first in a cold storage cabinet so that the second body part 104 forms the front side of the shelf structure.
    In some embodiments the two body parts may diverge from being fully parallel 25 to each other. Preferably, the two parts form less than a 20 degree angle toward each other.
    A first and second support part 106, 108 connects to the body parts 102, 104 so that the body parts and support parts form a stable structure. Preferably, the body 30 parts and support parts are attached to each other near the end of the parts so that they form a square or rectangle like structure. The parts may be attached with screws, by welding and/or other suitable mechanical means.
    The shelf structure 100 comprises two movable parts 110, 112 that are movable 35 along the first and second body parts 102, 104 so that the distance between the two movable parts is changeable. The changeable distance between the movable parts allows varying sized baking trays or baking sheets on the shelf structure. Optionally, one of the movable parts is stationary and the other is movable.
    20175537 prh 12 -06- 2017
    The two body parts 102, 104 comprise a number of slots 114a-114d for placing the movable parts to different widths. The slot construction is beneficial for detaching the movable parts. Preferably, the body parts comprise three slots in both 5 ends of the body parts that allow three preferable widths such as 370 mm, 400 mm and 450mm. Optionally, the body parts comprise more than three slots such as 4, 5 or 6 slots in both ends of the body part.
    The movable parts comprise at least two downwards extending edges 116a, 116b 10 that may be inserted into the slots. Additionally, the movable parts comprise an upwards extending edge 118 for preventing the baking tray and/or baking sheet from moving sideways. Preferably, the movable parts are metal plates. The metal plates may be bent with a press brake so that the upwards and downwards extending edges are formed, for example.
    Preferably, the parts in the shelf structure are stainless steel. Alternatively, parts of the shelf structure may be metal, plastic, composite, other steel and/or other durable material suitable for cold storage use. For example, for optimizing costs, in one embodiment parts 102 and 104 may be stainless steel and parts 106, 108, 20 110 and 112 may be plastics or composite material.
    Figure 3 illustrates a cold storage cabinet 250 with rounded side protrusions that supports the shelf structure of the present invention. The present invention allows the production of such storage cabinets which are easy to clean. Preferably, a 25 cold storage cabinet has a temperature between +15 °C and -30 °C.
    Consequently, a skilled person may on the basis of this disclosure and general knowledge apply the provided teachings in order to implement the scope of the present invention as defined by the appended claims in each particular use case 30 with necessary modifications, deletions, and additions.
