Definitions

  • the invention relates to a hospital bed with a mattress frame with at least one lying surface part which is adjustable in its inclination and also lockable in the respectively desired inclination position.
  • the state of the art include sick beds in which, for. B. the backrest can be tilted via an unlockable gas pressure spring and can also be locked in the desired tilt.
  • sick beds in which, for. B. the backrest is coupled via a pair of handlebars and a pivot axis with an adjusting rod which extends through a larger-diameter opening of a clamping tab, for the purpose of a positive connection can be pivoted with respect to the longitudinal axis of the adjusting rod, but can also be unclamped again by means of an opposite pivot connection, whereupon the adjusting rod can move through the opening of the clamping tab and thereby the incline of the backrest can be adjusted.
  • Lockable gas pressure springs can become defective so that they can no longer perform their function. This can e.g. B. cause a lying surface part, for. B. a backrest or a heart part, can suddenly fall down from the set angular position, which has corresponding consequences especially for older people or seriously ill people.
  • the frictional connection between the clamping tab and the adjusting rod can also be inadvertently canceled, so that the adjusting rod slides through the opening of the clamping tab and the part of the bed surface connected therewith suddenly changes its angular position.
  • the invention has for its object to improve a patient bed according to the generic term in that it meets higher safety requirements, with a simple construction.
  • the construction is relatively compact, since both parts, namely the lockable gas pressure spring and the adjusting rod, can be arranged close to each other. In principle, the construction of the bed itself does not need to be changed.
  • the braking and blocking devices from a central location by remote control, for. B. by a Bowden cable, a lever linkage or the like.
  • a handle or a button can be provided, by means of which the braking and blocking devices can be unlocked and possibly also blocked again.
  • the braking and blocking devices can be switched on and off simultaneously. This can be done by the same lever, the same button, that is, the same lever linkage or the same Bowden cable, so that the number of individual parts can be kept low.
  • the braking and blocking devices can be switched on and off in succession. As a result, the braking and blocking action does not suddenly disappear when the braking and blocking devices are unlocked.
  • the braking and blocking devices are protected, but also largely hidden from the eye of the beholder, arranged below the mattress frame and thus also below the bedding, so that the visual impression of the patient's bed is not impaired on the one hand and the operator movable parts of the brake on the other - and cannot accidentally touch the blocking device.
  • the solution according to claim 7 meets the requirement constructively favorable, namely that usually at least some parts of the lying surface in the vertical plane, for. B. should be adjustable.
  • the bed surface frame with the other bed surface parts can also be adjusted with respect to the floor, that is to say height adjustable, and / or the entire bed surface can also be tilted about at least one axis.
  • the z. B. parallel side-by-side braking and blocking devices in a favorable manner in the angular adjustment of the part of the bed surface involved in the movements.
  • a special bearing is saved at least at one end for one of the braking or blocking devices.
  • the braking and blocking devices are infinitely variable, ie in any position of their parts, to be brought into and out of function, so that there is a very fine adjustment option for the reclining lying surface part.
  • the lying surface part can only be locked in certain intermediate positions, that is to say intermittently, by the braking and blocking devices.
  • Claim 13 describes an embodiment in which the braking and blocking devices are to be locked against one another in a form-fitting manner, for example by serrations or perforations.
  • a preferred embodiment is described in claim 14 .
  • the adjusting rod is assigned two clamping plates so that it can be non-positively locked by the clamping plates in both directions, that is to say both under tension and pressure.
  • Claim 18 also describes an advantageous solution.
  • the adjustment rod is provided with a preferably fine toothing, so that there is a correspondingly large number of adjustment options for the inclinable lying surface part.
  • Reference number 1 denotes a mattress frame, which is only partially illustrated in the drawing, however, because it can have the usual configuration.
  • a backrest 4 with a cross member 5 is pivotably arranged in the vertical plane via pivot axes 2 and 3 and can also be locked in the different angular positions in the manner described below.
  • an axis 8 is mounted, with which an eye 9 of a lockable gas spring 10 is also pivotally mounted in a vertical plane, that is to say parallel to the levers 6 and 7.
  • a trigger part is designated 11.
  • This trigger part 11 is designed as a push-in button or rod, which is not apparent from the drawing Unlocking or valve parts controls. If the trigger part 11 is pressed into the gas spring 10 in the axial direction, the parts of the gas spring 10 which are axially displaceable relative to one another can be adjusted until the trigger part 11 z. B. has been brought back to its starting position, in which the gas spring 10 is blocked.
  • the axis 13 has a bore 14 with a thread penetrating it, into which the part 12 of the gas spring 10 is screwed.
  • the axis 13 is rotatably supported at its two ends in levers 15 and 16, which, like the levers 6 and 7, are arranged at an acute angle to the longitudinal axis of a crossbar 17 in the direction of the floor and in the direction of the levers 6 and 7.
  • the levers 6, 7 or 15, 16 can also be arranged in any desired way under different angles.
  • the levers 15 and 16 are also integrally connected to the cross member 17.
  • the cross member 17 is in turn integrally connected to the mattress frame 1.
  • the levers 15 and 16 are arranged at a distance and parallel to one another and carry between them those arranged at the free end of the levers 15 and 16 Axis 13.
  • a further pivot axis 18 is arranged, the longitudinal axis of which runs parallel to the longitudinal axis of the axis 13 and which is also mounted in the levers 15 and 16.
  • the clamping plate 19 is rectangular in shape both in the side view and in cross section and has in the region of one of its narrow sides 20 a bore 21 which penetrates it transversely and through which the pivot axis 18 engages with play.
  • the width of the clamping plate 19 is smaller than the clear distance measured orthogonally to the longitudinal axes of the levers 15 and 16, so that the clamping plate 19 does not abut the levers 15 and 16 but can pivot between them.
  • the clamping plate 19 can also have a different shape, for. B. square, polygonal, or the like.
  • the clamping plate 19 has at its end section facing away from the bore 21 a penetration opening 22 through which an adjusting rod 23 extends.
  • the diameter or the transverse dimensions of the penetration opening 22 are larger than the diameter of the adjusting rod 23, so that the clamping plate 19 can be tilted relative to the adjusting rod 23.
  • the penetration opening 22 can be circular, but also different, e.g. B. square or polygonal. Accordingly, the adjustment rod 23 can be formed, for. B. also square or polygonal in cross section. There is then even a better adhesion to the clamping plate 19.
  • the adjusting rod 23 is also pivotally mounted at one end on the axis 8 in the vertical plane and dimensioned so long that it protrudes with a considerable length from the penetration opening 22 on the side facing away from the levers 6 and 7.
  • the length of the adjusting rod 23 is dimensioned such that the bed surface part coupled with it and to be adjusted, e.g. B. the backrest 4, can be angularly adjusted to the desired extent and still protrudes a certain length of the adjusting rod beyond the penetration opening 22 of the clamping plate 19 in the maximum angular position.
  • the adjusting rod 23 is on each side of its longitudinal axis in the region of the lever 6 and 7 a bearing part 24 and 25 attached.
  • These bearing parts 24 and 25, like the levers 6 and 7, are formed from sheets which have bent parts 24a and 25a, the longitudinal axes of which each run at an obtuse angle to the parts 24b and 25b pointing upwards and at a distance from one another.
  • these parts 24b and 25b In their central longitudinal section, these parts 24b and 25b have an opening through which a bearing bushing 26 and 27 extends, each of which has a flange 28 and 29 in one piece.
  • the flanges 28 and 29 face outwards.
  • the bushings 26, 27 and the flanges 28 and 29 connected to them in one piece have coaxial bores of the same diameter, through which the axis 8 extends.
  • an enlarged bolt head is designated, which rests against the flange 28 from the outside.
  • the axis 8 has a groove in which a locking ring 31 is inserted.
  • the parts 24b and 25b are arranged at a distance from the eye 9 of the lockable gas spring 10.
  • the mutually facing end faces of the bushings 26 and 27 are also at a distance from the lateral boundaries of the length-adjustable part 9 the gas spring 10 arranged.
  • the parts 24b and 25b are mounted on tapered longitudinal sections of the bushings 26 and 27. Characterized the adjustment rod 23 is located with its longitudinal axis below the longitudinal axis of the gas spring 10. If the locking ring 31 is removed, the axis 8 can be pulled out, whereby z. B. the gas spring 10 is quickly replaceable.
  • the reference numeral 32 denotes a release rod, the longitudinal axis of which extends transversely to the longitudinal axis of the mattress frame 1.
  • the trigger rod 32 is arranged in bearings, of which only the bearing 33 can be seen from FIG. 1.
  • This bearing 33 is fastened to the inside of one spar of the mattress frame 1.
  • the bearing, not shown, is arranged and fastened accordingly.
  • the trigger rod 32 has at its outwardly facing ends a hand lever 34 and 35, which are directed in the same direction and are within the projection of the mattress frame 1, so that they do not protrude outwards, but below the mattress frame 1 from the person standing next to the bed can be gripped and pivoted in the vertical plane.
  • a hand lever 34 and 35 which are directed in the same direction and are within the projection of the mattress frame 1, so that they do not protrude outwards, but below the mattress frame 1 from the person standing next to the bed can be gripped and pivoted in the vertical plane.
  • other suitable structural designs can also be used within the scope of the invention.
  • a lever 36 is connected to the trigger rod 32 and is coupled to a further lever 38 via a horizontally lying pivot axis 37.

  • the frictional connection between the clamping plate 19 and the adjusting rod 23 must first be released and the gas spring 10 must be unlocked via the release part 11.
  • this trigger part 11 lies against the side wall 40 of the clamping plate 19 facing the gas spring 10.
  • the trigger part 11 is also pressed into the gas spring 10 and this unlocks it. Only when the frictional connection between the clamping plate 19 and the adjusting rod 23 has been lifted on the one hand and the gas spring 10 has been unlocked on the other hand, can the coupled adjustable part, e.g. B. adjust the backrest 4 in its downward inclination. This results in double security. If one of the levers 34 or 35 is released again, this results in an immediate inclination (FIG. 2) of the clamping plate 19 with respect to the longitudinal axis of the adjusting rod 23, as a result of which the frictional connection is immediately restored between the clamping plate 19 and the adjusting rod 23 . Besides, can the trigger part 11 return to its initial position, whereupon the gas spring 10 is blocked.
  • the coupled adjustable part e.g. B. adjust the backrest 4 in its downward inclination. This results in double security. If one of the levers 34 or 35 is released again, this results in an immediate inclination (FIG. 2) of the clamping plate 19 with respect to the longitudinal
