Definitions

  • the invention relates to a bathtub insert consisting of a base frame, a seat plate, a guide device consisting of two pairs of scissor arms between the base frame and the seat plate, and a hose that can be filled with water as a lifting device, the closed ends of which are attached to the base frame and the seat plate, the seat plate being two has lateral pivot plates biased into the plane of the seat plate.
  • a bathtub insert of this type is known from EP-PS 74 460.
  • the seat plate extends over the entire length of the bathtub and also has end-side swivel plates, so that when the seat plate is lowered, no gaps can arise between it and the bathtub, in which the disabled could get caught.
  • long bathtub inserts have a double guide device, ie two front and two rear scissor arm pairs. If the disabled person can do without lying in the tub, a simpler use of the bathtub with a shorter seat plate, which only extends over about half the tub length, is sufficient.
  • Such bathtub inserts are, for example, from US Pat. No. 2,725,578 and. 2,772,721 is known.
  • the object of the invention is to design the bathtub insert of the type mentioned at the outset in such a way that injuries to the use of the bathtub insert by the disabled are avoided with certainty.
  • a roller blind-like, flexible cover is provided on the front of the bath insert between the seat plate and base frame, the width of which is almost equal to that of the base frame and one end of which is on the seat plate or the base frame strengthens and the other end of which is fastened to a winding tube which is rotatably mounted on the base frame or on the seat plate, into which a torsion spring with a pretensioning which holds the cover even in the lowered position of the seat plate is inserted.
  • the advantage of the invention is that all moving parts between the seat plate and the base frame are covered, so that the disabled person is not exposed to the risk of jamming, either with the feet or with the hands.
  • the cover naturally has the greatest tension when the seat plate is in the high position and this is so strong that the handicapped cannot even want to book the cover from the straight stretched position. But even in the low position and shortly before reaching the low position, the cover has a sufficient clamping force, so that there is also effective protection here.
  • Another advantage of the invention is that the pretensioning of the cover is sufficient for the seat plate to be pulled onto the base frame by itself, so that the rest position of the bathtub insert is at the same time the transport position, so that additional locking devices are not required.
  • the two side swivel plates on the seat plate automatically attach themselves to the bathtub and prevent them a column formation here. So the handicapped person is also protected from being pinched.
  • the cover extends upwards and backwards at an angle in the range from 10 ° to approximately 20 ° in the high position of the seat plate.
  • the pulling action of the cover thus takes place with a forward component exerted on the seat plate.
  • This is particularly advantageous in connection with a guide device designed in a certain shape, which according to the invention ensures that when the seat plate is lifted, it moves backwards simultaneously with a component.
  • the ends of the four arms of both pairs of scissor arms each have a fixed pivot bearing and a pivot bearing in a sliding piece which can be displaced in a rail, that the four fixed pivot bearings are arranged in the rear region of the bathtub insert and that between the common central joint axis of all four arms and the two pivot bearings on the front bottom sliding pieces each measured lever length is greater than the three other lever lengths measured between the central joint axis and the pivot bearings.
  • the seat plate moves approximately parallel to the sloping end surface of the tub.
  • the one between the seat plate and the tub end Area formed gap can not be reduced so that there is a risk of injury by pinching.
  • this type of movement of the seat plate has the advantage that it gradually assumes a slight inclination towards the rear when lifting, which has the great advantage that the disabled cannot slide forward on the seat plate.
  • a further feature of the invention is that the lever length measured between the common central joint axis and the two pivot bearings on the front table-top sliding pieces is smaller than the other three lever lengths. This measure alone would lead to an inclination of the seat plate to the front, which is undesirable. In connection with the significant enlargement of the arm levers engaging on the sliding pieces on the bottom, such a forward inclination is not only compensated for, but is converted into a downward inclination towards the rear when the seat plate is in the high position.
  • the two rear arm levers engaging on the fixed bearings are preferably of the same length.
  • the Front lower arm length is in the range of about 10% to about 20% longer, while the shorter upper front arm length is about 7% to about 15% shorter.
  • This means that the two arms of each pair of scissor arms are of different lengths, namely that the arm leading to the rear upper fixed pivot bearing of the seat plate is in the range from about 10% to about 15% longer than the other arm.
  • This arm length ratio is preferably 1.12.
  • the bathtub insert generally designated 10, consists of a base frame 12, a seat plate 14, two pairs of scissor arms 16 and a lifting device in the form of a hose 18, the closed ends of which are fastened to the base frame 12 and to the seat plate.
  • the seat plate 14 has two lateral pivot plates 20 which are prestressed in the plane of the seat plate and extend over the entire length of the seat plate 14. At a distance from the rear end of the seat plate 14, a backrest 22 is detachably inserted therein.
  • the front end of the bath insert 10 is closed between the floor frame 12 and the seat plate 14 by a flexible roller blind-like cover 24.
  • the cover 24 has almost the same width as the base frame 12.
  • the upper end of the cover 24 is fastened to the underside of the seat plate 14 by means of a strip 26, while the lower end of the cover 24 is wound on a winding tube 28 into which an approximately coaxial Torsion spring 30 is used.
  • One end of the winding tube 28 is closed by a plug 32, which has a coaxial stub shaft 34 projecting outwards, which is in a bearing block 36 the outside of the base frame 12 is rotatably mounted.
  • an end piece 37 is rotatably inserted, in which a coaxial hollow shaft 38 is rotatably mounted, the opposite end of which is guided in a disk ring 40 inserted into the winding tube 28.
  • a coaxial extension 42 of the hollow axis 38 projects through a bore in the end piece 37 and is clamped in a rotationally fixed manner with the hollow axis 38. This. coaxial extension 42 is non-rotatably supported in the left-hand bearing block 44 and secured against rotation by means of a radial pin 46.
  • the torsion spring 30 is screwed onto a threaded section of the end piece 37 which engages in the winding tube 28.
  • the opposite end of the torsion spring 30 is reduced to an inner diameter which corresponds to the outer diameter of the hollow axis 28. If, before the winding tube 28 is assembled, the hollow axis 38 is rotated while the winding tube 28 is held tight, the end of the torsion spring 30 with reduced diameter is jammed on the hollow axis 38. And the torsion spring 30 can be put into a strong state of tension. In this state, the winding tube 28 is then mounted in the manner described on the base frame 12 and the other end of the cover 24 is on the Seat plate 14 attached.
  • Each pair of scissor arms 16 consists of two arms 48, 50 of different lengths. All four arms 48, 48, 50, 50 are pivotally connected to one another by a common central joint axis 52.
  • the arm 48 has a swivel bearing 54 fixedly attached in the rear region of the seat plate 14 and a lower swivel bearing 58 provided on a sliding piece 56.
  • the sliding piece 56 is guided displaceably in a rail 60, the central axis of the arm 48 being aligned with the central axis of the rail 60 in is the same vertical longitudinal plane.
  • the rail 60 only had to extend from the front to approximately in the central region of the base frame 12, in the exemplary embodiment it extends over almost the entire length of the base frame shown here as a plate, which increases stability.
  • the two arms 50 are each mounted on the inside next to the rails 60 on rear fixed floor pivot bearings 62 of the floor frame 12, while their upper ends are mounted in pivot bearings 64 by sliding pieces 66, which in turn are guided in rails 68 which are longitudinally displaceable, which on the underside the seat plate 14 are attached.
  • the extension to the rear results in greater stability.
  • the arms 48 are connected to one another by a hollow cross strut 70 to form a rigid swivel frame 72. Installation is very simple, using a tie rod 74 which extends into the two arms 48 and on which nuts 76 are screwed on the end.
  • the outer pivot frame 72 formed by the two outer arms 48 and the cross strut 70 thus has a U-shape.
  • the two inner arms 50 are also connected to one another adjacent to the upper sliding pieces 66 by a cross strut 76.
  • a corresponding cross strut 78 is also provided near the fixed pivot bearings 62, so that an inner pivot frame 80 which is closed all round is formed.
  • the lower position of the bathtub insert is shown, the outer swivel frame 72 rests on the bottom rails 60 and the inner swivel frame 80 is level with the outer swivel frame 72, the upper rails 68 touching the arms 50 of the inner swivel frame 80.
  • the arm has relative to the central articulation axis 52 48 has a lower lever 48a and an upper lever 48b and the arm 50 has a lower lever 50a and an upper lever 50b.
  • the two lever lengths 50a and 48b are of equal length, so that the pivot axes 54 and 62 of all four arms are aligned in the transverse direction when the bathtub insert is in the lowered position.
  • the lower lever 48a is about 13% longer than the two levers 50a, 48b with the same catch. It is thereby achieved that the seat plate 14 is simultaneously displaced rearwards during the lifting process and thereby brings the seat plate 14 into an inclined position which is inclined downwards towards the rear.
  • the lever 50b of the arm 50 is approximately 9% shorter than the two arm levers 50a, 48b of the same length.
  • the winding tube 28 at the bottom of the Seat plate are stored while the mounting bar 26 is attached to the floor frame.
  • the base plate shown can also be dispensed with in the base frame 12 if the base rails 60 are connected by transverse rails to form a base frame, to which the pivot bearings 62, the bearing blocks 36, 44 for the winding drum 28 and the bottom end of the hose 18 are then attached .
