Definitions

  • the invention relates to a back support for bath lifts, which have a base frame, a seat plate and a lifting frame arranged in between with a lifting device, the back support having a base element that can be placed on the seat plate and locked on it, on which a backrest from a steep position about a first transverse axis pivoted backwards and downwards into a flat position and supported at least in the steep position by a support member mounted on the base element and engaging on a wall web projecting from the back of the backrest.
  • Such a back support is known from EP-A-0622042.
  • the support member consists of a piece of hose that can be filled with pressurized water.
  • a separate manually operated control valve is required for filling and emptying the hose section.
  • a simpler back support is known from EP-B-0347652, in which a latching device is installed in the pivot bearing of the backrest, which makes it possible to lock the backrest in a multitude of inclination positions in a finely graduated manner.
  • the backrest must be moved against the spring force in the direction of the swivel axis in order to release the locking. This disengagement movement can only rarely be carried out by an auxiliary person, but by the disabled person sitting on the seat plate.
  • a back support which is commercially available under the trade name Meyra, which also enables latching in a steep position, with the backrest having to be raised in order to release the latching mechanism so that it can be given away in a flat position.
  • This lifting usually also requires the use of an auxiliary person.
  • the object of the invention is to improve a back support of the type mentioned in such a way that it can be moved from the supported steep position into a flat position and vice versa in a simple manner and a disabled person can carry out this adjustment himself.
  • the wall web is arranged in a vertical plane perpendicular to the backrest and has a guide track into which a runner arranged at an upper end of a swivel arm engages and the swivel arm on the base element by a second Transverse axis is pivotally mounted, which is spaced from the first transverse axis and that the guide track comprises a long track section extending at least approximately along the backrest, which has a lower region, which is associated with a bypass section which forms a path loop.
  • This loop is designed in such a way that the lower ends of the long track section and the bypass section open into a connecting track section, that the bypass section re-opens into the long track section at a height distance from the connecting track section and that a backstop is assigned to at least one of the outlet points.
  • the swivel arm constitutes the support member.
  • the swivel arm swivels upwards and forwards, its runner sliding down in the long track section of the guide track until it reaches the connecting track section.
  • the swivel arm supports the backrest in the steep position. In order to adjust the backrest from this steep position into a flat position, all that is required is a short swivel stroke of the backrest to the front, as a result of which the runner reaches the rear end of the connecting track section, where he enters the bypass section after overcoming the backstop.
  • the backrest can be freely swivel backwards into a flat position, in which it is supported on the wall of the bathtub.
  • the rotor of the swivel arm has passed through the bypass section and has re-entered at its upper mouth in the long section. Above this upper mouth, at which the long track section branches into its lower area and the bypass section, the runner glides downwards when the backrest is swiveled up and upwards when the backrest is lowered. The runner can only be moved downwards in the lower area of the long path section and only upwards in the bypass section.
  • the long track section is unlimited at the top, so that the backrest is supported on the floor element or the seat plate of the lifter.
  • a further development of the invention is that a locking piece can be inserted into the guideway and positively secured against displacement in order to achieve a certain flat position of the backrest with a defined angular position. The runner then supports the swivel lever on the backrest via this locking piece.
  • the locking piece is preferably plate-shaped and engages in transversely aligned slots in the guideway. Several pairs of slots can be provided at short longitudinal distances to allow fine adjustment of the flat position of the backrest.
  • the lower region of the long guideway with the bypass section and the connecting track section forms a parallelogram-like or also rectangular-like structure, the individual track sections not necessarily having to run in a straight line.
  • the rotor is designed as a bolt acted upon by a compression spring.
  • the guideway then consists of a groove arrangement and the backstop is configured by a shoulder in the groove bottom.
  • the groove bottoms of the major part of the groove arrangement lie in a common plane and each step is preceded by a rising ramp.
  • Each heel has a heel surface which is at least approximately perpendicular to the groove bottom and which is flush with a side surface of a subsequent web section.
  • the end points of the connecting track section form a straight line which encloses an angle of at most 45 ° with the longitudinal center line of the swivel arm. In a preferred embodiment, this angle is less than 10 °.
  • the long web section opens in the lower region into a short end section angled towards the backrest and a first backstop is assigned to this outlet point and this end section in turn ends at an angle in the connecting section and this further outlet station also has one Backstop is assigned.
  • the short end section preferably forms a right angle with the long track section. It is thereby achieved that the pivoting up of the backrest is forcibly stopped when the runner enters the short end section of the long track section. By a slight swiveling back of the backrest, the runner then reaches the front end of the connecting track section, where it supports the backrest in the steep position.
  • the tangend placed on the bypass section at its junction in the connecting track section forms an angle greater than 90 ° with the swivel arm longitudinal extension when the runner is located at this junction. This angle need only be a little larger than 90 ° to avoid self-locking.
  • a particularly advantageous feature of the invention is that a leg spring is arranged coaxially to one of the two pivot axes, preferably the pivot arm pivot axis, which is tensioned when the backrest is pivoted downward and the spring force of which is sufficiently dimensioned to at least approximate to the released backrest to swivel into the steep position.
  • the disabled person only needs to straighten his upper body from the lying position, with the backrest following thanks to the built-in spring.
  • the backrest finds its defined steep position on its own or is reached when the back is leaning against the backrest.
  • the disabled finds a secure hold when lifting and lowering the seat plate of the lifter on the backrest and he can release the backrest with a simple release stroke for lowering to the flat position by swiveling the backrest slightly forward until the runner on the swivel arm Backstop has happened.
  • This release stroke of the backrest can be carried out particularly easily if an additional, forward-facing actuating lever is provided on the backrest, so that it only needs to be pressed downwards by the disabled person.
  • This actuating lever is preferably pivotally attached to the side of the backrest, so that it is only pivoted forward into its functional position up to a stop when necessary, but is otherwise hidden behind the front surface of the backrest in a rest position.
  • the main components of a bath lifter according to FIG. 1 are a floor frame 12, a seat plate 14, a guide frame 16 and a lifting hose 18 which can be filled with pressurized water.
  • a back support 20 is detachably fastened to the seat plate 14.
  • the back support 20 has a base plate 22, which is used to rest on the seat plate 14 and in its front region supports a backrest 24 pivotably about a first transverse axis 26.
  • a plate-shaped pivot arm 28 is pivotally mounted about a second transverse axis 30 in the rear region of the base plate 22 and engages with two coaxial bolts 32 projecting from the outside in each case in groove tracks 34 which are formed on the inside on two wall webs 36, which in turn are molded or attached to the back of the backrest 24.
  • the groove track 34 has according to FIG. 3 shows a stepped cross section, whereby a shoulder 38 is formed, which is followed by a recessed area which forms the groove bottom 40.
  • the rotor 32 has a sleeve 42 which protrudes laterally from the plate-shaped swivel arm 28 and engages in the groove track 34 up to the shoulder 38.
  • a pin 44 is slidably mounted in the sleeve 42, which is pressed outwards by a helical compression spring 46 and rests with its end face on the groove bottom 40 in the recessed groove area.
  • the groove track 34 has a first long track section 48 which extends essentially along the backrest 24, namely closely adjacent and parallel to the back of the backrest.
  • This long track section 48 is angled slightly to the rear to create space for a short end section 50 which adjoins at right angles.
  • This end section 50 opens into a connecting track section 52 which forms an angle of approximately 45 ° with the angled end 50 of the long track section 48.
  • This connecting track section 52 in turn opens at the end facing away from the backrest 24 into a bypass section 54 which, apart from slight curvatures, extends along the long track section 48 and opens into it at an acute angle.
  • a backstop 56 is provided which consists of a shoulder 58 which extends to the groove bottom 40 and which is preceded by a ramp 60.
  • a backstop 56 does not have to be provided at each mouth, as shown.
  • the plate-shaped swivel arm 28 already has a tendency to swivel in the direction of the backrest due to its gravity when the runners 32 are in the lower region of the long track section 48. If the swivel arm 28 is additionally equipped with a return spring which exerts a swiveling moment acting in the same direction as gravity, the first backstops 56 at the ends of the track sections 48 and 50 and 54 could be omitted. Only the backstop 56 at the junction of the connecting track section 52 into the bypass section 54 is mandatory.
  • FIGS. 7 and 8 show a slightly modified groove track 34, in which the long track section 48 opens directly into the connecting track section 52 without the angled end section 50.
  • the groove track 34 is thereby somewhat simpler, but this entails a certain loss of comfort, because when the backrest 24 is swung up, it is no longer stopped automatically, but could be pivoted further upwards until the runner 32 reaches the bypass section 54. This can be easily prevented, however, since when the backstop 56 is overcome, the bolts 44 of the runners 32 snap into the groove depressions at the end of the long path section 48 with an audible click.
