Definitions

  • the invention relates to a medical elevator with two side frames which can be folded by means of cross joints and pivotable about a common horizontal axis, on which steerable front wheels and preferably larger rear wheels which can be driven by hand are rotatably arranged and on which upward-pointing backrest bars holding a backrest, Depending on the folding movement, upward and downward movement of the seat pillars carrying a seat surface and a footrest are supported by means of support arms.
  • FIG. 1 designates two side frames of a foldable medical elevator (wheelchair), which are constructed identically, but are mirror-inverted in a few individual parts and are arranged in both side areas of the medical elevator.
  • Each side frame 1 has a rectangular basic shape (side view) and is made in one piece from plastic.
  • each side frame 1 has a front upright support bar 4, an upright guide bar 5 provided at a distance behind it and an upright guide bar 6 arranged at a distance behind it.
  • These three bars 4 to 6 are replaced by two between the bars 4 and 5 and 5 and 6 extending, horizontal spacers 7 are preferably held at the same distance from one another, these spacers 7 running in the upper longitudinal end region of the upright spars 4 to 6 and forming the spar ends 4a to 6a which protrude above these spacers 7.
  • the two guide bars 5, 6 have the same length (height) and the middle guide bar 5 shows at its lower end a horizontal bearing sleeve 8 which runs in the direction of travel and extends beyond the guide bar 5 on both sides, while the rear guide bar 6 at its lower end has one in the direction of travel extending bearing spar 9 holds, which also protrudes on both sides over the guide spar 6 and extends coaxially to the bearing sleeve 8.
  • a horizontal spacer 10 extending in the direction of travel extends between the bearing bar 4 and the guide bar 5, which runs at a distance above the bearing sleeve 8 and connects to the lower end of the shorter bearing bar 4.
  • a horizontal fastening stub 11 which runs in the direction of travel, is attached to the rear guide bar 6 and is shorter in length than the lower, parallel bar 9.
  • the upright bearing and guide bars 4 to 6 and thus the resulting mounting pieces 4a to 6a, the horizontal bearing bar 9 and the horizontal bearing sleeve 8 are formed by tubes, the horizontal spacers 7 and the mounting pieces 11 are also designed as tubes and the horizontal spacer 10 is formed by a full or hollow rod with a circular, angular or rounded corner section.
  • the pipes 4 to 7, 8, 9 and 11 have a circular cross section.
  • a molded, web-shaped stiffener 16 runs between the bearing bar 4 and the spacer 10 and the spacer and the guide bar 5 and the bearing sleeve 8.
  • All of the aforementioned parts 4 to 12 and 16 are made in one piece from plastic to the side frame 1 in terms of manufacture and, furthermore, web-shaped stiffeners 17 are integrally formed in support of the bearing plates 12 between them and the bearing beam 4, so that the entire side frame 1 forms a unit.
  • Each pair of the two articulated struts 3 is equipped at the lower end of the length with a horizontal bearing tube 18 which extends coaxially between the bearing sleeve 8 and the bearing bar 9 and which pivotably engages in these two parts 8, 9 with a pivot axis (not shown).
  • the upper end of the pairs of articulated struts 3 is fastened to a horizontal seat spar 19 which extends in the direction of travel and which rotatably engages through two bearing sleeves 20, each of which has a guide spar 21 directed downward; the one guide bar 21 in the middle (5) and the second guide bar 21 in the rear guide bar 6 and these, the seat bar 19 carrying guide bars 21 are guided in height in the guide bars 5, 6 of the side frame 1 and move when the Side frame 1 via the hinge struts 3 in the guide bars 5, 6 up or down (for the use position in the guide bars 5, 6 and for the folding position out of the guide bars 5, 6) (cf. FIG. 5).
  • These two seat spars 19 each carry a flexible seat 22 in the form of a tarpaulin, a cloth or the like made of leather, synthetic leather, textile, plastic or the like, which automatically takes part in the folding and unfolding.
  • an axle block 23 with a plurality of axle holes 24, which are recessed at a distance from one another (next to and on top of one another) and arranged to accommodate a rear wheel axle 25, is arranged around the guide bar 6, spacer 7 and fastening piece 11;
  • This axle block 23 is divided into two parts and overlaps the frame parts 6, 7, 11 in the joint area from both sides and is fastened to these parts 6, 7, 11 by screws or the like.
  • the larger, preferably manually drivable rear wheel 26 is mounted with its axle 25 in an axle hole 24; Due to the large number of axle holes 24, rear wheels 26 of different sizes can optionally be attached to the axle block 23.
  • each axle block 23 receives an upright backrest spar 27 with its lower end, which is designed at the upper end to form a handle 29 bent against the direction of travel.
  • a backrest 28 is fastened between the two backrest bars 27 and is designed to be flexible in accordance with the seat surface 22.
  • an upright bearing pin 13 is fixed and in this bearing pin 13 a support arm 14 of the footrest 15, preferably the foot plate, is hung with tabs 38.
  • the position of the support arms 14 pointing forward in the direction of travel can be achieved by a support plate 39 extending on the support arm 14 between the tabs 38 and a locking pin 4o, in which the support plate 39 rests on the bearing bar 4 and the locking pin 4o in the bore 41 of the bearing bar 4 is held and engages in a bore 42 of the contact plate 39 (see. Fig. 1,3 and 5).
  • a larger or a smaller side part 43, 44 according to FIGS. 1, 2, 6 to 10 can be detachably attached to the two side frames 1.
  • receiving pieces 45 made of plastic fastened like a clamp, each showing a vertical insertion slot 46 into which the side part 43, 44 is inserted with underside webs 47, so that it runs upright and in extension of the side frame 1.
  • the insertion slots 46 lie outside the side frame outside, so that the seat spars 19 with their upright guide spars 21 can be moved up and down undisturbed on the side parts 43, 44.
  • the side parts 43, 44 are each fixed in position by a rear locking clip 48 provided in the upper end region on the backrest beam 27, this locking clip 48 extending on the inside of the side part and partially engaging around the backrest beam 27.
  • the smaller side part 44 is less in height and length than the side part 43 and has only two webs 47; it extends from the backrest spar 27 forward over the two spars 4 and 5 (see FIG. Lo).
  • the larger side part 43 has three plug-in webs 47 and extends from the backrest spar 27 to the front fastening piece 4a.
  • the preferably gradual height adjustment of the armrest 49 is carried out by a locking pin 52 which is mounted on the outside of the side part 43 and optionally engages in one of the holes 53 provided in the height direction in a retaining bar 50.
  • the side part 43, 44 with plug-in webs 47 and locking clip 48 is made in one piece from plastic, the guide grooves 51 also being molded in the production in the side part 43.
  • the support arm 14 with tabs 38 and contact plate 39 is also made of plastic.
  • each support arm 14 is divided into two and in the footrest 15 two metallic spars 14a are inserted, which can be inserted in the tubular support arm 14 in an infinitely variable manner and can be fixed by a clamp 14b (cf. 1 and 5).
  • the side parts 43, 44 are formed by plates with a rectangular basic shape; at the front end of the plate, the side parts 43, 44 are tapered and / or curved from top to bottom and then show a trapezoidal shape.
