Definitions

  • the object of the present invention is a tray with supporting legs.
  • Trays with supporting legs are known, which comprise a support plane with raised edge, which constitutes the true tray, with which supporting legs are connected.
  • Such a tray can be of the folding type, i.e., the legs are articulated with the support plane in such a way that they can be rotated until they come to rest against the support plane, so that the tray takes a substantially planar configuration.
  • the tray can also be of non-folding type, viz., the legs can be fixed relatively to the support plane.
  • Such a type of tray is used in particular in bed for consuming meals, i.e., as a supporting structure on which the containers which contain food and beverages rest.
  • the tray is usually positioned astride the user, with the legs of the tray resting on the upper surface of the bed.
  • the support plane normally takes a substantially horizontal position, in order to prevent the containers containing food and beverages from slipping along it.
  • the tray for reading or writing, it can be comfortable for the user to incline the support plane relatively to its horizontal position, towards the same user.
  • the purpose of the present invention is of proposing a tray with supporting legs, the support plane of which can be inclined.
  • a tray with support legs comprising a support plane with which the support legs are linked, characterized in that said support legs are telescopically articulated, with the possibility of being blocked relatively to each other, in order to bring said support plane to an inclined position relatively to a reference position, and maintain it in said inclined position relatively to said reference position.
  • the depicted tray generally indicated by the reference numeral 10, comprises a support plane 11 with a raised edge 12, both of rectangular shape. In correspondence of each one of the shorter sides of the support plane 11, with the same plane two supporting legs 13 and 14 are linked.
  • the leg 13 is of fixed length, and is constituted by a rectilinear element 15 having an "U"-shaped outline.
  • the leg 14 is more complex, and can be telescopically extended. It comprises an internal element 16 having a circle-arc-shape, with an "U"-shaped outline, which is linked with the element 15 by means of a cross-­piece 17, with which it forms one single piece.
  • the leg 14 furthermore comprises an external element 18, having a circle-arc-shape, with an "U"-shaped outline, inside which the element 16 is slidingly inserted, and which extends into a portion 19 which transversely links the same element 18 with the element 15.
  • the cross-piece 17 is linked with the support plane 11 by means of two hinges 20.
  • the portion 19 of the element 18 is connected with the element 15 by means of a hinge 21.
  • the element 18 is provided with two longitudinal bent edges 22 opposite to each other, which retain the element 16 inside the element 18.
  • the element 16 is provided with an elastically yielding tongue 23, suitable for entering slots 24 provided on one of above-said two edges 22; in the form of practical embodiment shown, the slots 24 are two, and are provided in the nearby of end points of the element 18.
  • the tray 10 as disclosed has two operating configurations, i.e., the configuration depicted in Figures 1 and 2, and the configuration depicted in Figures 3 and 4.
  • each internal element 16 and its respective external element 18 slide, with a relative rotational movement, along a circle-arc-shaped trajectory, corresponding to their circle-arc development, with the rotation centre being in the respective hinge 21.
  • each leg 14 the tongue 23 enters the lower slot 24 in order to block the internal element 16 on the external element 18, so as to prevent the leg 14 from extending, and maintaining the tray in such a configuration.
  • each internal element 16 In order to be able to move each internal element 16 relatively to the corresponding external element 18, and, therefore, to turn from the one configuration to the other one, it is enough to apply a pressure to the tongue 23, so as to disengage it from the slot 24; during the relative movement between the elements 16 and 18, the tongue 23 is elastically deformed by the edge 22 in which the slots 24 are provided, until said tongue elastically snaps into one of the same slots.
  • each couple of elements 15 and 18 around the hinge 21 is limited in both directions of rotation by stop edges 25 of the element 15, against which the portion 19 of the element 18 comes to rest.
  • the elements 15 are provided with a lower end 31 having a circle-arc-shape, in order to favour the rotation of the elements 15 on the base, on which the tray 10 rests, during the movement of inclination of the support plane 11, and during the reverse movement.
  • the tray 10 can be bent, until is takes a substantially planar configuration. This is achieved by rotating the supporting legs 13 and 14 around the hinges 20, until the same legs come to stay, throughout their length, under the support plane 11, and along it, as shown in Figure 7.
  • each cross-piece 17 is provided with a wing 26 destined to elastically interfere against a wall 27, well visible in Figure 8, of the edge 12 of the support plane 11 during the rotation of the cross-piece 17 from the closed position of the legs 13 and 14, corresponding to the configuration of Figure 7, to the open position, and vice-versa.
  • the unintentional return of the same legs to their closed position is prevented by the above said elastic interference, which can only be won by means of an intentional forcing by the user.
  • the elements 15 and 18 are each provided with a small protrusion 28, destined to enter, by elastic click, a corresponding dead hole 29 provided inside the interior of a wall 30 of the edge 12 of the support plane 11, as shown in Figure 9.
  • a folding tray with supporting legs, which an inclinable support plate, is provided, so as to meet the requirements stated in the introduction.
  • All the disclosed and illustrated elements of the tray 10 can be made from a plastic material, the cheapness of the tray being hence increased.
  • the legs 13 and 14 of the tray 10 are completely housed inside a hollow 32 provided under the support plane 11, defined by a lower extension 33 of the raised edge 12. In that way, the folded tray 10 can be used as a normal tray, without supporting legs.
  • the raised edge 12 is suitable for retaining on the support plane any objects which are resting on it.
  • the tray can be provided with supporting legs telescopically articulatable relatively to each other, in order to enable the support plane to be inclined relatively to the horizontal position.
  • each telescopic leg have a circle-arc-shaped configuration and extension, but it can have as well a straight configuration and extension.
  • legs have to be connected with each other by means of cross-pieces, even if such an arrangement would supply stability to the whole structure, but they can also be independent from each other, at least in correspondence of their bottom end.
  • blocking elements functionally equivalent to as herein those disclosed and illustrated can be used, such as, e.g., screw elements fastening by friction the components of the telescopic leg against each other, as well as different types of blocking means.
  • a system different from the one as above seen can be used, by exploiting the elastic interference, e.g., an elastic-click blocking system, a screw blocking system, or still other blocking systems can be used.
  • blocking elements can be used, which are functionally equivalent to those as herein disclosed and illustrated, constituted by a protruding element and a hole, e.g., stop elements which move from a blocking position to a release position, or still other means.
  • Blocking means can be provided as well, which are positioned, e.g., on the hinge means of the support legs, which perform the task of retaining these latter both in their open and in their closed positions.
  • the components of the tray can be given various shapes.
  • the support plane can be, besides rectangular, also square, circular, or it can also be of other shapes, and may also be without a raised edge;
  • the supporting legs can have an outline different from the "U"-shaped outline, e.g., they can have a circular outline; and so forth.
  • the hollow which receives the legs of the tray in their folded position can also be absent.
