Definitions

  • the subject of the present patent application is constituted by a "TILT ARTICULATED BED", the structure of which clearly differentiates a support frame, a box frame, in turn divided into three sectors connected to one another. articulated with respect to the support frame by a series of transverse axes connected together by two pairs of sets of levers, and a locking mechanism for fixing the assembly in the desired position.
  • articulated beds are known in which the position of the bedside and the leg area is adjusted separately by means of the corresponding mechanisms, independent of each other, which essentially consist of a series of connecting rods and of an endless screw, actuated by a crank, which in both cases is handled with a certain effort by a person situated outside the bed, the central section being immobile, corresponding to the abdominal region of the user.
  • the carcass of the box spring is completed with the corresponding transverse blades, the metal mesh or louver for the support of the corresponding mattress, in the version bed proper, or it is completed with covers of canvas or other suitable material, or with plates or grids, which allow the use of this structure as a lounge chair for the garden, the terrace, the solarium, or even as a stretcher for treatment rooms, cosmetic offices and others.
  • Another object of the invention according to the Patent of invention n ° 9000883 of the same holder, is that the bed can be folded easily, by means of simple operations, until obtaining a maximum reduction of the volume, which would facilitate its storage and transport, the assembly also being obtained by means of simple operations.
  • the bed of the invention is characterized in that the end panel of the bed base is directed towards the side of the foot of the bed, is connected with the frame by means of two connecting rods, one anterior and the other posterior, articulated by their ends to this panel and to the frame, along the axes perpendicular to the longitudinal axis of the bed, while the end panel of the mattress which is directed towards the bedside is articulated to the frame along a transverse axis and it is further connected to this frame by means of a connecting rod which is articulated by its upper end to the panel and which is connected to the frame with ability to slide through a braking device.
  • the front connecting rod which connects the end panel on the side of the foot with the frame has a length greater than the distance between the axis of articulation of this connecting rod to the frame and the panel, when this panel is in a horizontal position.
  • the axis of articulation between this connecting rod and the panel is moved relative to the axis of articulation of this connecting rod with the frame, towards the adjacent transverse side of the bed base when this bed base is in horizontal position and towards the opposite side when it adopts the maximum folding position.
  • this connecting rod is constantly pushed towards the first cited position by means of a spring.
  • the rear connecting rod which connects the end panel with the frame has a length equal to the distance between the axis of articulation of this connecting rod to the frame and the panel, when this panel is in a horizontal position.
  • the two connecting rods which connect the external panel directed towards the foot with the frame are each composed of two parallel bars united by two crosspieces, the bars of which are located in a direction perpendicular to the longitudinal axis of the bed and are connected by their ends. with rotational capacity, one of them to the frame and the other to the panel, by means of sockets integral with this frame and with the panels.
  • the rear connecting rod which connects the end panel with the frame is articulated to this panel at a point close to the point of articulation between this panel and the intermediate panel.
  • the braking device commented on above is composed of jaws between which pass the connecting rods of the end panel directed towards the bedside. These jaws can be brought together or separated, by blocking or releasing the connecting rods, by means of an actuating lever.
  • the person occupying the bed can, by means of a light pressure, adjust the position of the box spring, between a horizontal and flat situation and another partially folded, in which the extreme panel directed towards the bedside certain angle with the intermediate panel, while the other extreme panel remains in a horizontal position, but moved longitudinally towards the center of the bed.
  • the bed of the invention has no pins or shock absorbers which increase the cost and complicate its construction.
  • the bed frame is foldable, so that it even allows posterior folding of the bed base, making it possible to obtain a minimum volume for storage and transport.
  • the complete folding and unfolding of the bed is obtained by simple operations.
  • the bed frame consists of two independent foldable carcasses, each of which is located under one of the end panels of the bed base. These two foldable carcasses are connected by means of a removable intermediate flat carcass.
  • Figure 1 is a schematic side view of an articulated tilting bed, with the carcass of the bed base inclined in its three sections.
  • Figure 2 is a schematic side view of an articulated tilting bed, with the frame of the box spring in a horizontal position in its three sections.

  • This set of levers allows the user himself, by pressing with his head and his shoulders, without abandoning the bed, on the bedside (3), of the bed base frame which rests on an axis (17) provided in the basic carcass, the entire carcass of the box spring rocks in proportion to the pressure exerted, being able to fix the assembly in the desired position by means of a blocking system, which will be described later.
  • the telescopic bar (12) by virtue of the expansion spring (13) to which it serves as a guide, normally presses on the articulation point (11) of the branch (9), (9 ′), connected to the point d hinge (7) between the lower section (5) of the bed base and the intermediate section (4), and for this this lower section (5) tends to normally occupy the same position.
  • a brake mechanism represented in FIG. 4, which can be actuated by the user himself, without moving from the bed, by means of the lever ( 18) an eccentric (19) with two slopes connected to a bar (20) constituted by a double concentric tubular element whose inner tube (20 ′) is welded by one of its ends to the fixed element of the eccentric (19), while the external element (20) sectioned, has coupled in the opposite end a stud provided with an adjusting nut (21), and it is welded to the support frame of the bed, in its inclined section (2 ⁇ ); these concentric cylindrical elements (20), (20 ′), have pairs of through orifices (22), (22 ′), opposite and provided with tolerance, which are crossed by the corresponding rods (23), (23 ′), welded to the axis (6) of articulation between the bedside (3) of the box spring and the middle zone (4), so that when the lever of the eccentric is actuated by giving it a turn by 90 °
  • FIG. 6 another locking or brake mechanism has been provided for this tilting articulated bed, which mechanism is coupled to the axis or to the bar (17) of articulation of the bedside section ( 3) of the bed base, at the connection angle between (2) and the section (2 ⁇ ) of the support base of the bed.
  • this axis (17) consists of two concentric cylindrical elements, the external element (17) of which is sectioned is fixed through rings welded to the base carcass and to the frame (3) of the bed base, and it has in one of its ends a stud and an adjusting nut (24), while the opposite end of the inner cylinder (17 ′) is welded to the fixed half (25 ′) of an eccentric with two slopes ; in this latter axis (17 ′) are coupled two series of pressure discs (26), provided with corresponding arms alternately joined through the corresponding pins (27), (27 ′) to the base frame and to the bedside frame (3 ) the box spring carcass, with the interposition of the corresponding compensation washers; in this way when the lever (29) is actuated by 90 °, connected to the movable half (25) of the eccentric, the internal cylindrical element (17 ⁇ ) and the external cylindrical element (17 ′) move axially in the opposite direction, giving rise to the compression of the disc blocks and the immobilization of the entire mechanism.
