DETAILED DESCRIPTION
(9)
(10) However, in the particular illustrated embodiment, the covering elements 10A,10B are used in connection with a food bar arrangement 100 which comprises canteen or pan holding arrangements 103A,103B adapted to receive and hold a plurality of canteens or pans 104 in which fresh food products are to be kept. It further comprises a refrigerating 200 for cooling the canteens, and hence the food products provided therein, for keeping the food products at a desired temperature, e.g. above 0 but below 8 C., or within a more specified temperature interval.
(11) The holding arrangements 103A,103B comprise or are connected to cupboard or bench arrangements 300 comprising cold wells and being adapted to receive the canteens or pans in such a manner that openings of the canteens or pans make the food accessible for a customer from a first and a second outer side section of the holding arrangements 103A,103B, hence allowing a customer to choose and pick from the canteens or pans, here from two sides.
(12) The covering elements 10A,10B are adapted to cover the canteens or pans from above so that the content is protected in time periods between customers accessing the content, or when refilling the canteens or similar.
(13) The covering elements 10A,10B can be transferred from an open position or an open state, in which access to the content in the canteens is provided. In
(14) Said rear walls, or rear sections, are in an advantageous embodiment disposed at a distance from one another, leaving space for a refrigerating or cooling element 200, particularly a cooling tower, between them. The upper end of the cooling element or the cooling tower 200 in some embodiments is contiguous with the upper end of a mounted covering arrangement 100 (when the covering elements are in their closed positions).
(15) In other embodiments the cooling element 200, or the covering arrangement 110, is adapted to have such a height that the upper end of the cooling element 200 will be disposed below the position assumed by the upper end or edge of the covering element(s) in its (their) closed position. Alternatively the cooling element(s) protrudes above the covering arrangement in its closed position, although its active portion, as far as its cooling functionality is concerned, preferably terminates at the upper end or edge of the covering arrangement.
(16) It should however be clear that the covering arrangement according to the present invention with advantage also can be used irrespective of the location of any cooling element.
(17) Each covering arrangement 10A,10B is here equipped with an actuating element 19A,19B, e.g. a gripping element, a handle or similar by means of which a user, e.g. a customer accessing the products in the canteens, can bring the covering arrangement 10A,10B from a closed position to an open position and vice versa. In the shown embodiments the actuating elements 19A,19B extend along the lower ends of the front sections 11A,11B, or adjacent said lower ends. The actuating elements may of course be of any other form or shape, disposed in any different manner, the purpose being to facilitate or enable that the covering arrangement to be opened/closed in an easy and safe manner. Preferably actuating elements 19A,19B are disposed all along the long side of the food bar, so that e.g. a customer in front of the food bar can open/close the covering element with ease irrespective of his current position.
(18) The front section 11A,11B of a covering element 10A,10B is preferably made of a transparent material, e.g. of any appropriate plastic material known in the art. The side sections and the rear sections may according to different embodiments be made of the same material as the front section, or of other appropriate materials, which may be the same or different for the side and the rear sections. Particularly also the side sections are made of a transparent material.
(19) In order to transfer a covering element 10A,10B from a closed to an open position, it is moved in a vertical direction between a first, lower, position, the closed position, (covering element 10B in
(20) The covering elements 10A,10B are movable between said first, closed, and said second, open, positions by means of the covering arrangement further comprising, or being connected to, a mounting (and driving) structure comprising guide rails in which a slide or pulley mounted on the covering element can run.
(21) In order to bring a covering element 10A,10B from a closed position to an open position, a slight force has to be overcome to allow it to subsequently slide or move upwardly, substantially with no resistance, until it reaches the upper, open, position. Vice versa, when it is to be moved from the upper, open, position to the lower, closed, position, a slight force, somewhat higher than the slight force referred to above for the closing operation, has to be overcome after which it is moved automatically slowly downwards. Such opening and closing movements can be achieved in different manners as will be discussed below. An advantageous embodiment is discussed with reference to
(22) The mounting structure may be provided with vertical parallel guide rails for cooperation with the respective rear outer edges of a single cover element, or it may be a dual mounting structure adapted to receive two covering elements 10A,10B as in
(23) Another important feature is the provisioning of the first side sections 12A.sub.1, 12A.sub.2, 12B.sub.1, 12B.sub.2, and in particular of second, preferably, but not necessarily, fixed or detachably mountable, second side sections or additional side walls 13A.sub.1,13A.sub.2, 13B.sub.1,13B.sub.2 (the latter not shown in
(24) Thus, through the particular arrangement of the rear sections of the covering elements adjacent to a cooling element, and movably with respect thereto, such that when a covering element is in an open position, the rear section is moved upwards, exposing a larger area of the cooling element, hence resulting in an increased cooling of the canteens, and further the implementation of the second side sections, the covering arrangement will, to a considerable extent, contribute to keeping an even temperature distribution in the food bar.
(25) The cooling element 200 is in different advantageous embodiments arranged with respect to, or in, a holding arrangement 103 such that, when the canteens 104 are taken up therein, each canteen back wall, distant from an opposite canteen front wall located adjacent an inner side of the holding arrangement 103 at its outer side, where customer access is provided, will be located close to, facing it, preferably throughout the entire area forming the back wall.
(26) The holding arrangement 103 in one embodiment, to which the invention however by no means is limited, comprises holding means adapted to hold the canteens or pans in an inclined position such that outer, upper, ends or side edges, of the canteens will be disposed at a lower level than opposing inner, upper ends, or side edges. Bottom sections of the holding arrangement may be disposed such that a distance is left between the bottom surface of the holding arrangement, forming a cold well, and the bottom portions of the canteens.
(27) At least a part of the cooling arrangement will thus, in such an embodiment, be located adjacent the outer sides of the back walls of the canteens in a mounted position in a holding arrangement.
(28) The covering arrangement according to the invention may be used for such a food bar arrangement, substantially as disclosed in PCT/SE2014/000028 claiming priority from Swedish patent application No. 1350368-5. In such an implementation a first portion of cooling arrangement protrudes above the upper edges of the back walls of canteens placed in the holding arrangement, whereas a second section of the cooling arrangement extends downwards towards, but ending at a certain distance from, the bottom of a well or trough of the holding arrangement such that it will be located adjacent substantially the entire back wall of each canteen. Through the positioning of the canteens in an inclined manner, outwardly, downwards away from the cooling arrangement, and at least a portion of the cooling arrangement extending upwardly above the inner upper side edges of the back walls, and the cooling arrangement being divided into a (communicating) upper and lower portion, separated by means of a dividing plate, the cooled air surrounding the upper inner part will flow downwards, outwards above the canteens containing the food, due to the dividing plate, hence not being allowed to pass, flow, vertically to the cold well, but is prevented to do so by the dividing plate. Through the second lower portion of the cooling arrangement covering the entire back walls of the canteens and a larger space being formed below the cooling arrangement, air with a lower temperature will be distributed and flow towards the outer end sections, under the canteens, cooling them from below as well as from above.
(29) In the advantageous embodiment shown in
(30) The canteens in each row may be also in an embodiment as disclosed in
(31) Although

(33)
(34) The springs 151A,151B are arranged to be pivotally connected, each separately, over a pivot point to allow the opening and the closing movement of the covering elements to be eccentrically driven, hence allowing a soft closure after being brought over the pivot point, and an automatic opening at crossing the pivot point in the opposite direction. As an alternative to a dual wheel guide or trolley there may be two separate upper trolleys or guiding elements, one for each covering element.
(35)
(36) The wires are connected to the respective springs 151A,151B which when a respective covering element is actuated, are pivoted over the pivot point such as to provide an eccentrically controlled movement of said covering element.
(37)
(38) Thus, a covering element can easily be opened, but once it is open, a higher spring action has to be overcome in order to close the covering element, hence avoiding any closing operation from unintentionally being initiated during access to a canteen, and preventing the cover from falling down, or unintentionally being closed, in which case a customer might be injured, or the cover be damaged.

(42)
(43) The second side sections 13A.sub.1 (not shown in this FIG.), 13A.sub.2 may according to different embodiments be fixedly, or detachably, connected to, either the mounting structure 141.sub.1 (not shown in this FIG.), 141.sub.2 or the respective mounting elements, or alternatively fixedly or detachably connected to the food bar holding arrangement 103. They may alternatively be connected to the covering elements 10A,10B, e.g. to inner sides of the first side sections 12A.sub.2, 12B.sub.2 of the covering elements in a sliding manner, e.g. via cooperating grooves and nuts or by means providing a similar functionality, and securable by means of appropriate fastening means to the food bar arrangement 100, for example to the holding arrangement 103.
(44)
(45)
(46) At the lower ends 122A.sub.1, 122A.sub.2, of the rear side frame elements a respective slide 142A.sub.1, 142A.sub.2 or a carriage is provided. Said slides 142A.sub.1, 142A.sub.2 or carriages are adapted to slide in guiding rails as discussed with reference to
(47) The height of the rear frame section in a mounted state thereof is smaller than that of the side sections 12A.sub.1, 12A.sub.2 in a preferred embodiment since it is adapted for being mounted on a food bar arrangement with a refrigerating element extending adjacent to the rear section 15A, the purpose of the shorter dimension of the height of the rear section 15A is to allow cooling by means of the refrigerating element. When the covering element 10A is lifted or elevated to the open position, a larger area of the cooling element will be exposed or uncovered, thus at least to some extent compensating for the warmer air entering the space above the canteens when the covering element 10A is in an open position. Hence a good or a similar cooling capability will be provided independently of whether the cover element 10A is in an open or in a closed position.
(48) In some embodiments auxiliary fans (not shown) may be used to further compensate for cooling losses when the cooling elements are in an open position, for example at high temperatures in the surroundings, or such fans may also be implemented as an additional means.
(49) The covering arrangement is arranged so as to leave a space above the canteens allowing air to circulate due to the cooled air flowing outwards, (particularly downwards due to the inclination of the canteens 8 in some embodiments) over the food, since cool air has a lower density.
(50) It should be clear that the invention is not limited to the specifically illustrated embodiments, but that it can be varied in a number of ways within the scope of the appended claims. Particularly it is not limited to any particular number of covering elements, sizes and shapes of covering arrangements or covering elements, nor of the mounting structure, nor of the materials used. In different embodiments the frame structure of the covering element may be made of Al, stainless steel, an alloy with similar properties or of a plastic material.
(51) Also the covering arrangements, or specifically the covering elements, may be adapted for use with food bars, specifically holding arrangement, which are adapted for taking up one row of canteens, it may be square shaped to take up four rows of canteens arranged with a cooling arrangement in the center of pair wise oppositely arranged canteen back walls, or it may even comprise a circular or oval holding arrangement with surrounding canteens with correspondingly adapted shapes of the canteens or the canteen back walls. The shape and the size of the covering arrangement is then adapted correspondingly, the main issues being that it is movable in a vertical direction, is provided, preferably but not necessarily, with both of, first and second side sections, and with one or more rear sections facing a cooling or refrigerating arrangement, and so disposed that it in an opened position leaves a larger area of the cooling arrangement free, hence partly compensating for the losses in cooling that occur during opening.
