Definitions

  • the invention relates to a device for adjusting the angular position of a pivotable support surface, in particular the support surface for the head end of the mattress in a bed frame.
  • Bed frames with an adjustable head and / or foot part of the frame are known, each of which is pivoted up by a thrust drive about an axis of rotation parallel to the lying surface. Because of the small amount of space available between the lying surface and the floor, long lever arms cannot be used for the pivoting movements and, accordingly, fairly powerful thrust drives are necessary, which represent the greatest cost factor in such beds. Bed frames of this type are used in particular in hospitals and for nursing care, but also in private households, but are very expensive because the adjustable head and / or foot section is integrated in the special construction of the bed frame. People in need of care should in particular be able to operate the adjustable head part themselves in order to be able to position themselves for eating or reading etc. without outside help, which is why a motor drive is necessary for the adjustable part.
  • the object underlying the present invention was to provide a device for raising a part of the lying surface, in particular the head part, which can be used in any normal bed frame, which is provided with a motor drive and is easy to transport to more than one bed frame to be able to use one after the other, and in particular it is considerably cheaper than the conventional devices of this type.
  • the device If the device is to be used for any normal bed frame, it can because of the variety of designs the support for the mattress in the form of a slatted frame or spring frame etc. the space below this support surface for the mattress for accommodating the drive and the adjusting device are not used.
  • the problem here is to accommodate all the elements necessary for swiveling a support surface up and down, including the drive, in the smallest of spaces, because when not in use, the support surface swiveled downwards of the devices inserted under the mattress should not impair lying comfort or not be noticeably noticeable make, which is why the device should be extremely flat.
  • the object is that two frames pivotally connected to one another by means of an axis of rotation on a wheel, one of which is intended to lie horizontally on a support and the other forms the support surface which can be adjusted in a variable angular position with respect to the horizontal, under the effect of at least one in the area of the rotating axis, between the two frames effective prestressed torsion spring bar and at least one between the two Frame supported gas spring are pushed apart in the sense of an angle enlargement and that both frames are connected to each other by flexible traction means, by means of which the frame for the purpose of continuously changing the angle with the aid of a drive means arranged on one frame and acting on the traction means against the action of torsion spring bar and gas spring are pullable against each other or can be pivoted apart under the action of which.
  • Two torsion spring rods which are arranged parallel to the axis of rotation and to one another, are held with one end on opposite sides of the one frame and pressed with one respective angled other end against rolling elements arranged on opposite sides of the other frame.
  • two gas springs are expediently articulated with their one end on opposite sides of the one frame and their other end on opposite sides of the other frame.
  • a torsion spring bar and a gas spring work together on opposite sides and cause the high the pivoting support surface forming frame is pushed up.
  • a torsion spring bar and a gas spring are each arranged on the same frame side in such a way that as the angle between the two frames decreases the spring force of the pretensioned torsion spring bar increases the moment exerted by the gas spring on the frame in the sense of increasing the angle.
  • the torsion spring rod which is expediently preloaded during installation with a rotation angle of 50 °, is tensioned by a further approx. 70 ° when the two frames are pulled together. This strong spring force decreases when the frame is swung open, if at the same time the gas spring acting in the same direction exerts an increasing moment on the frame with an increasing effective lever arm.
  • a steel cable to one frame on opposite sides as a flexible traction means, which two steel cables are guided over deflection rollers arranged on the other frame and are attached with their other ends parallel to one another on a pivot lever mounted in the other frame, which indicated by one in the other frame arranged electric lift motor with pivoted on the pivot lever threaded spindle.
  • the motor swivels the swivel lever in one direction, the frame swung up under the action of the torsion spring bars and the gas springs is pulled down against the horizontal frame by pulling on the steel cables, while the frame held by the steel cables is reversed when the motor rotates and the direction of movement of the swivel lever is released for swinging up.
  • the device has a particular frame 1 to be placed on a horizontal base, in particular a bed frame (not shown in the drawing), on the one edge of which a further frame 3 of substantially the same size is pivotally attached by means of an axis of rotation 2.
  • a further frame 3 of substantially the same size is pivotally attached by means of an axis of rotation 2.
  • the frame 3 with the surface 5 forms the support surface against which the head-side end region of a mattress (not shown in the drawing) is supported, and which support surface should be set in any angular position relative to the horizontal frame 1, which should be possible by actuating a motor.
  • two torsion spring bars 6 and 7 extend in the lower frame 1 almost over the entire width of the frame 1 and can be passed through two bearing blocks 8 and 9.
  • the torsion spring bar 6 in the drawing is angled by 90 ° behind the bearing block 8 and its straight end is held in the bearing block 9 in a rotationally fixed manner, so that the entire length of the torsion spring bar can twist relative to this end that is held in place.
  • the torsion spring bar 7 behind it is angled by 90 ° in the drawing in front of the bearing block 9 and its free end is held in the bearing block 8 in a rotationally fixed manner.
  • the angled ends of the two torsion spring bars 6 and 7 are each pressed against a roller 10 and 11, which on the inside opposite sides of the frame 3 are mounted.
  • the angled ends of the two torsion spring bars move relative to the rollers.
  • the two torsion spring bars 6 and 7 are installed with a prestress corresponding to a swivel angle of 50 °.
  • the two torsion spring bars act in the sense of increasing the angle between the two frames, wherein they exert the greatest spring force when the two frames 1 and 3 lie parallel one above the other.
  • two gas springs 12 and 13 are attached to opposite sides of the two frames with one end on frame 1 and the other end on frame 3.
  • Each gas spring also works with a pressure of approx. 40 kg in the sense of increasing the angle between the two frames 1 and 3. If the two frames 1 and 3 lie one above the other in parallel, the gas spring can only be used act on the frame 3 with a very short effective lever arm. If the spring force of the two torsion spring bars 6 and 7 decreases with increasing angle between the frames starting from the position with frames 1 and 3 lying one above the other, the moment exerted by the two gas springs becomes increasingly larger due to the increasing effective lever arm, so that between the a slightly fluctuating force in the sense of increasing the angle between the frames is effective.
  • This force of the springs is counteracted by a cable pull, through which the two frames 1 and 3 are pulled against each other.
  • a first steel cable 14 is attached at one end to the frame 3 and guided over a deflection roller 15 which is rotatably mounted on the frame 1 at the level of the gas spring 12 and then via a further deflection roller 16 mounted in the corner of the frame 1 and finally via one on the longitudinal side of the frame arranged deflection roller 12 out.
  • the other end of this steel cable 14 is attached to a tensioning device 18, which is attached to a pivot lever 19.
  • This pivot lever 19 is pivotally mounted on the frame 1 by means of a pivot pin 20.
  • a second steel cable 21 is fastened at one end to the opposite side of the frame 3, guided over a deflection roller 22 mounted in the frame 1 at the level of the gas spring 13, then via a further deflection roller 23 arranged in the frame corner of the frame 1 and finally via a pulley 24 arranged on the longitudinal side of the frame, which is mounted on the same axis as the pulley 17 for the other steel cable 14.
  • the end of the steel cable 21 is fastened to a tensioning device which, like the tensioning device 18, is also fastened to the pivot lever 19.
  • a tensioning device which, like the tensioning device 18, is also fastened to the pivot lever 19.
  • the tensioning devices 18 and 25 are shown attached to one another on the swivel lever 19 for clarification, but in reality these fastening ends lie one above the other on the swivel lever, since the steel cables would otherwise be pulled unevenly.
  • the pivot lever 19 is pivoted with the aid of a lifting motor 26 in the direction of arrow 27, the frame 3 being pulled against the action of the two torsion spring bars 6 and 7 and by pulling on the two steel cables 14 and 21 both gas springs 12 and 13 is pulled against the lower frame 1.
  • the two frames 1 and 3 are parallel one above the other. From this end position, the frame 3 can be brought into any desired angular position with respect to the frame 1 by actuating the motor 26 in the opposite direction.
  • the lifting motor 26 is pivotally mounted in the frame 1 by means of a pivot pin 28 so that the motor can carry out the lateral movement caused by the movement of the connection point between the motor and the pivoting lever 19 on a circular arc.
  • a motor is selected which is somewhat too weak in relation to the required force and is therefore supported by a gas spring 29, which is connected in parallel to the motor 26 with one end likewise pivoted to the pivot lever 19 and with the other end to the frame 1 and exerts a force in the direction of movement on the pivot lever, which leads to a reduction in the angle between the frames.
  • the lifting motor 26 is connected to the mains via a cable 30. The direction of movement of the lifting motor can be reversed by actuating a switch 31.

Abstract

Le dispositif présente deux cadres (1, 3) reliés entre eux par un axe de rotation (2) et tenus écartés l'un de l'autre par des barres de torsion (6, 7) et par des ressorts pneumatiques (12, 13) précontraints et disposés près de l'axe (2). Le cadre supérieur incliné (3) sert d'appui pour la partie d'un matelas située près de la tête d'un sommier. Dans le but de modifier l'angle d'inclinaison du cadre supérieur (3), on prévoit, fixés sur celui-ci, des câbles en acier (14, 21), qui sont déviés par des poulies (15, 16, 17, 22, 23, 24) disposées sur l'autre cadre (1) et reliés à un levier pivotant (19) sur ce dernier cadre (1) et actionné par un moteur de levage (26). En actionnant le moteur de levage (26) dans un sens, les câbles (14, 21) font pivoter un cadre (1) contre l'autre (3) et contre la réaction des barres de torsion (6, 7) et des ressorts pneumatiques (12, 13). En l'actionnant dans le sens contraire, les cadres (1, 3) s'écartent l'un de l'autre sous l'effet des barres de torsion (6, 7) et des ressorts pneumatiques (12, 13).
