Definitions

  • the subject of the present invention is a special mechanism that can be fitted to the frame supporting the mattress of a bed in order to enable it to be easily moved vertically and tilted longitudinally simply by means of straightforward, easy manual actions.
  • Hand-powered mechanisms though normally relatively simple, are generally operated through a crank which is usually located in awkward positions, making it difficult and inconvenient to use.
  • Mechanisms powered by electromechanical devices are clearly not only complicated but also very costly and can give problems such as non-operation if the electricity supply is interrupted and all kinds of possible failures of the various components.
  • the object of the present invention is to overcome the problems indicated above and this is achieved with a mechanism forming the subject of the present invention, which, the better to explain its operation, is here described below in detail, purely by way of a non-restrictive example, with reference to the accompanying drawings which show schematically, in a series of figures in side view, the configuration of the mechanism and its operation. Specifically:
  • the mechanism that forms the subject of the present invention consists fundamentally of a lower frame 1 and an upper frame 2 connected to each other by a structure which will be described in detail later, all the parts making up said mechanism being made of suitable metal components.
  • Said lower frame 1 and said upper frame 2 are more or less identical to each other and will consist, in a manner known per se, of respective rectangular frames made up of suitable square- or rectangular-sectioned metal tubes, of which the figures referred to show only their two respective longitudinal members 11 and 21 located on one side, partly split as appropriate.
  • the lower frame 1 will stand on the floor S on suitable feet P and the upper frame 2 will be connected above in some appropriate way to the frame T supporting the mattress M by means of suitable connecting parts C.
  • the struts 3, 4, 5 and 6 are all identical and the two pairs formed by struts 3, 5 and by struts 4, 6 that are arranged symmetrically to each other about the hinged points in the centres of the respective longitudinal members 11 and 21, are hinged centrally to each other.
  • struts 3, 4, 5 and 6 will be provided with suitable rollers or blocks 31, 41, 51, 61 for guided longitudinal movement along the inside of their respective quadrilateral sections or in suitable tracks so that they can freely be slid in and out.
  • suitable longitudinal slots will of course be provided in the sections 11 and 21 along the respective slide segments (or in the equivalent tracks provided in these segments) in order to allow the associated spindles to pass along.
  • Said return springs 7 will be designed to provide corresponding tensions directed towards the centre which clearly, given the configuration of the structure described, will produce at the central hinged point of the longitudinal sections 21 of the upper frame 1 a vertical upward force sufficient to balance the weight pressing down on the frame 1 which, as a whole, is the sum of the weights of the frame 1 itself, the frame T, the mattress M and any sheets, blankets, etc. arranged on the latter (T).
  • fixing bars 13 and 14 are also attached to the outer ends of said struts 5 and 6, or rather to the pins of the latter's rollers or to the equivalent sliding blocks 51, 61.
  • These fixing bars 13 and 14 consist of respective rectangular plates arranged in line along the section forming the respective longitudinal member 11 and their other or inner ends are suitably contained, and slide in a guided manner, in a suitable housing 15, with two segments positioned side by side and provided, on their upper surfaces, with a number of notches capable of engaging the tooth formed on the free end of a pawl 8 which at its other end is connected to a suitable actuating lever 82 which is also hinged to a bracket 81 mounted on top of the longitudinal members 11.
  • a suitable return spring (not shown) will of course be provided to push said pawl 8 and hence its tooth projecting from its free end so that it engages in the notches formed on the terminal segments of the inner ends of said fixing bars 13 and 14.
  • Figures 4, 5 and 6 clearly illustrate the detail of the assembly used, as described above, for locking and releasing the present mechanism when set respectively in the fully up position, the intermediate position and the fully down position, and here the pawl 8 and its actuating lever 82 are indicated in heavy continuous lines in the locked position and in thin chain lines in the released position.
  • the bed can thus be moved from the raised position shown in Fig. 1 to the lowered position shown in Fig. 2 and vice versa, passing through all the possible intermediate positions on the way, of course.
  • said fixing bars 13 and 14 are each provided, on their respective adjacent segments located at their inner ends, and in which the locking pawl 8 tooth acts, with three notches set out at suitable distances from each other so that said tooth, when placed in the first notches, which are those formed towards their respective ends, fixes the structure in the raised position shown in Fig. 1, whereas when placed in the next, more inner notches, it fixes the structure in the intermediate position shown in Fig. 3, and lastly, when placed in the still more inner notches next after the last, it fixes the structure in the lowered position shown in Fig. 2.
  • the ability to tilt said upper frame 2 is made possible by dividing the two struts 3 and 4 into two halves exactly where they are hinged centrally to the corresponding struts 5 and 6, thus forming two inner portions 3a, 4a and two outer portions 3b, 4b identical to each other and hinged at their hinged central ends to the centre of the corresponding struts 5 and 6.
  • the hinged ends of the outer portions 3b and 4b are continued in the form of two short arms 3c and 4c extending inwards while also bending somewhat downwards, and to the free ends of said short segments 3c and 4c there are hinged, at their lower ends, two shaped plates 31 and 32 leading generally upwards, i.e. towards the upper frame 2.
  • These plates are also each additionally hinged in turn - at a point located on themselves intermediate between the points where their lower ends hinge on the free ends of said short arms 3c and 4c and the points where the corresponding outer portions 3b and 4b of the struts 3 and 4 hinge on the centres of the struts 5 and 6 - to the outer ends of two other mutually identical actuating links 91 and 92, the inner ends of which are then hinged to the free end of an actuating arm 93 which in turn is hinged to the centre of the respective longitudinal member 21 of the upper frame 2, that is to say in practice coaxially with the central pins about which the struts 5 and 6 are hinged.
  • said actuating arm 12 in the rest position is vertical and is continued upwards by the control lever 94.
  • said shaped plates 31 and 32 as clearly visible in Figures 1 to 7 and in particular much more clearly in Figures 8 and 9, comprise two segments positioned at a moderate distance from their respective intermediate hinged points to which, as stated, the outer ends of the actuating links 91 and 92 are hinged, which segments are also located towards the centre of the entire structure and include a plurality of notches for engagement with respective pins 95, 96 attached integrally to the inner portions 3a and 4a of the struts 3 and 4 towards their outer ends where they are hinged to the corresponding ends of the outer portions 3b, 4b and to the centres of the struts 5 and 6.
  • shaped plate 31 comprises, starting from its hinged point on the arm 3c, a rising segment separate from and somewhat diverging from the segment which is hinged at the bottom to the lower end of the arm 3c and at the top to the outer end of the associated actuating link 91, and its inner edge, namely that turned towards where this plate 31 is hinged to the outer end of the actuating link 91, is provided with said plurality of notches that are engageable on the respective pin 95; whereas shaped plate 32 is generally triangular, its side nearest the centre of the structure being provided with an equivalent plurality of notches for engagement on the respective pin 96.
  • Said outer portions 3b and 4b will thus be free to rotate about their respective hinged points on the outer ends of the corresponding inner portions 3a and 4a and about the corresponding central hinged points of the struts 5 and 6, thereby enabling the upper frame 2 to pivot about the central point where it is hinged to the upper ends of said struts 5 and 6.
  • pivoting can occur in either direction and when the desired tilt has been reached, the lever 94 is released: it will then be returned to its initial locked position by a suitable return spring (not shown), bringing said shaped plates 31 and 32 back towards their initial positions and their respective notches corresponding to this tilt will engage with the corresponding pins 95, 96. This immobilizes the upper frame 2 and hence the frame T supporting the mattress M in the corresponding tilted position.
  • each shaped plate 31, 32 which means therefore that only three different corresponding positions are possible, namely an intermediate horizontal position and only two different tilted positions in opposite directions. Obviously, a larger number of notches can be provided in order to offer a corresponding larger number of tilted positions.
  • this operation can likewise be carried out very simply and easily: the user simply exerts a slight push downwards and upwards at a point external to the central hinged point to bring about a corresponding pivoting of said upper frame 2 along with anything arranged upon it.
  • the pawls 8 that control the locking and consequent setting of the upper frame 2 in terms of height and the arms 93 that control its locking and consequent setting in terms of transverse tilt will be situated on both sides of the structure constituting the mechanism in question and each resulting pair will be interconnected by some appropriate transverse connection means such as a suitable metal rod.
  • the respective control levers 82 and 94 can be attached preferably removably to at least one end of these transverse connection means so that they can be placed on whichever side of the bed is most convenient for the user.
  • this mechanism makes it possible to alter, in a highly straightforward and easy manner, with only simple and convenient hand actions, both the height setting and the longitudinal tilt of the entire mattress assembly and associated accessories of a bed.
  • the structure forming said mechanism is very simple and is easy to fabricate. Its total cost is low and certainly much less than that of the many known mechanisms, especially those in which actuation is by more or less complicated electromechanical or other devices.
