Definitions

  • the invention relates to a standing aid, consisting of a base frame, a support frame connected to it from two tubes, and a seat support attached to the support frame and a seat body arranged on this seat support, the seat support with the seat body being adjustable in height along the support frame, and the seat body being adjustable in inclination can be.
  • DE 82 20 630 U1 shows a standing aid consisting of a base frame, a support frame connected to it, and a seat support attached to the support frame and a seat body arranged on this seat support, the seat support with the seat body being adjustable in height along the support frame.
  • the seat support is attached to the support frame with a clamp.
  • the disadvantage here is that the attachment is not secure enough and that handling is cumbersome, since two hands are always required for adjustment.
  • the seat body is also completely rigid and uncomfortable with respect to a lateral rotational movement.
  • a similar standing aid is known from DE 84 16 541 U1, here too the seat body can only be adjusted in height, the seat support consisting of tubes which can be moved in the support frame and which can be locked by means of an adjusting screw. Surrender here too the disadvantages of cumbersome operation, insufficient safety and a lack of comfort.
  • a version with a height adjustment of the seat body by a gas spring is also known.
  • this standing aid is relatively complex and does not offer the comfort of a lateral rotational movement of the seat body.
  • the object of the present invention is therefore to provide a standing aid which is simple to use, offers sufficient security when locking the height adjustment, has an inclinable seat body and dispenses with complex elements such as gas springs.
  • the standing aid is constructed in such a way that the seat body is fastened on a seat support, the seat support being pivotably mounted and lockable in different positions between two forwardly projecting legs of a locking body which can be displaced along the support frame.
  • the locking body can be brought into engagement with locking lugs with locking holes of the support frame and can be released again.
  • the seat support is U-shaped, is designed with legs directed downward and is mounted on an axis arranged in the upper region between the legs of the latching body, the axis engaging through elongated holes arranged in the legs and pointing upward and thus allows movement of the seat support along these elongated holes.
  • the legs of the seat support point in their lower area adjusting notches, which can be engaged or disengaged in accordance with the movement of the seat support in the elongated holes with locking means arranged in the lower area of the legs of the locking body.
  • the legs of the seat support are curved in the area of the adjusting notches and the adjusting notches are arranged in pairs on both legs at the same height.
  • a U-shaped handle part with inwardly extending legs and this handle part is pivotally mounted with the lower region of its legs about an axis below the connecting the seat support and the locking body between the legs of the seat support.
  • the legs of the handle part are provided in their upper region with a recess shaped as a control curve and the axis connecting the seat support and the locking body lies in this recess, with a first position of the axis leaving the control curve and a second position of the axis being lifted by the grip part Control curve is reached, and wherein in the first position a pair of the actuating notches are engaged and in the second position no actuating notches are in engagement with the latching means, and wherein in the second position the seat support between the legs of the latching body is freely pivotable.
  • the area in which the seat carrier can be pivoted between the legs of the latching body is limited by stops of the legs of the seat carrier on the latching means arranged in front of and behind the adjusting notches.
  • the latching body is formed from an upper plate and a lower plate, the two plates covering its legs at the top and bottom, and the lower plate having guide holes with little play for the support frame and the upper plate having elongated holes for the support frame, wherein in the elongated holes inwardly facing locking lugs are arranged such that they engage in the locking holes on the opposite side of the support frame of the support frame when the locking body is in a first position lying against the rear side of the elongated holes and that the locking lugs are not engage in the locking holes when the locking body is in a second position lying against the front of the elongated holes, the locking body being freely displaceable on the support frame in the second position.
  • a locking axis is arranged between the legs of the locking body and behind the legs of the seat support, which engages through two horizontally arranged elongated holes in the legs of the locking body outwards and forwards over the support frame.
  • the locking axis is pressed in the first position of the handle part by the legs of the seat carrier in the elongated holes and so the first position of the locking body on the support frame and thus the engagement of the locking lugs in the locking holes is locked.
  • the legs of the seat support are so far removed from the locking axis that this can assume a front position in the elongated holes, the latching lugs then coming out of engagement with the latching holes by a pivoting movement of the latching body.
  • the locking axis in the area in which it rests on the support frame is provided with the shape of the support body and is preloaded by springs arranged on the locking body to favor the locking of the locking lugs in the locking holes.
  • a standing aid is created in which both the height adjustment and the inclination adjustment of the seat body can be carried out with one handle, ie lifting the handle part.
  • the seat body is secure in its position locked and additionally secured by the bolt axis.
  • the standing aid is also developed in such a way that the seat support has an upper surface, that a hole is arranged in the upper surface approximately in the middle, that at least two inwardly curved grooves are arranged at regular intervals in the upper surface around the hole are that the grooves have a recess in their center and rise evenly from there to both sides, that the seat body carries a seat plate on its lower side, that a threaded rod extends downward from the seat plate through the bore in the upper surface of the seat support, that at the bottom of the seat plate corresponding to the grooves of the upper surface of the seat support also curved grooves with depressions and rising flanks are arranged, that balls are captively arranged between the grooves of the upper surface of the seat support and the grooves of the seat plate, that the threaded rod below the upper surface of the seat support It extends through at least one washer, an axial ball bearing, another washer, an elastic element, another washer and is fixed there with a nut.
  • this last-mentioned arrangement can also be used for standing aids without a height or incline-adjustable seat body.
  • Fig. 1 discloses a standing aid 1 according to the invention, consisting of a base frame 3 with non-slip feet 4 and a support frame 2 connected to it, with a slight inclination to base frame 3.
  • the inclination plays an important role in the stability of the standing aid.
  • the support frame is a U-shaped tube which is open at the top and connected to a bracket 21 and is fastened in corresponding recesses 20 in the base frame 3.
  • the support frame can also be constructed in one piece with the base frame or in several parts.
  • locking holes 7 are provided in pairs in both pipe sections on the rear side thereof at regular intervals. In these locking holes, as described further below, the locking body 6, which is displaceable on the support frame 2 hooked in and locked.
  • the latching body 6 has an upper plate 48 and a lower plate 49, which are provided with bores for the support frame 2 and partially cover two legs 42 directed forward and extending beyond the plates 48, 49, the latching body in the region of the plates 48, 49 is laterally provided with covers 19. Between the legs 42 projecting forward, the U-shaped seat support 8 is pivotally mounted about an axis 12, the legs 43 of which point downward and the axis 12 connecting the latching body 6 and the seat support 8 runs through their legs 42, 43, respectively.
  • the seat body 5 is fastened on the upper surface of the seat support 8. A handle part 9 can be seen between the legs 43 of the seat support 8.
  • Fig. 2 the panel 19 and the seat body 5 are omitted.
  • the support frame 2 Between the plates 48, 49 of the locking body 6, the support frame 2 can be seen, the tubes of which extend through elongated holes 10 in the upper plate 48 and bores 16 in the lower plate 49.
  • Rolling bodies run on the tubes of the supporting frame 2 and are connected to a locking axis described below, which are pressed against the tubes of the supporting frame 2 by springs 23 mounted in openings 24 of the legs 42 of the locking body 6.
  • the locking means 14 which extends through the legs 42 of the locking body and is designed as a thin rod, can also be seen here.
  • FIG. 3 shows the latching body 6, the seat support 8 with the seat plate 30 and the handle part 9.
  • the downwardly directed legs 43 of the U-shaped seat support 8 have adjusting notches 17 and laterally next to the adjusting notches 17 as stops 47 and at the same time serving as tabs 26.
  • the locking means can also consist of simple projections or short bolts.
  • the U-shaped handle 9 hangs, which is pivoted with its downward legs 45 about an axis 46 held in the legs 43 of the seat support 6 above the adjusting notches 17, as far forward and downward as this one in its Legs 45 arranged above the axis 46 and designed as a control cam 13, for the axis connecting the latching body 6 and the seat support 8.
  • the control curve 13 extends from a point closer to the upper side of the handle part 9 to a point which is further away from this surface.
  • the recess receiving this axis 12 is formed in the legs 43 of the seat support as an obliquely upwardly extending slot 44. If the handle part 9 is now raised at the front and rotates about its axis 46, the axis 12 connecting the latching body 6 and the seat support 8 moves along the control cam 13 in the legs 45 of the handle part 9, which inevitably means the seat support at a certain point 8 is lifted up a bit, which is made possible by the slot 44 for the axis 12. The lifted seat support 8 releases both the locking means 14 and the locking axis.
  • the seat support 8 is only lifted so far that the tabs 26 of the legs 43 of the seat support 8 limit its swivel range. Is the bolt axis released, i.e. can it move forward in the slot 21, the locking body 6 in the slot 10 in the upper plate 48 can be tilted upwards so far back that the locking lugs 11 come out of engagement with the support frame 2 and the locking body 6 so can be moved on the support frame 2. If the handle part 9 is released, it falls back into its first, locking position due to its own weight, provided that catches 11 of the catch body 6 and catch holes 7 of the support frame meet.
  • Fig. 4 shows a plan view of the upper plate 48 of the locking body 6 with the legs 42 projecting forward and the elongated holes 10 with the inwardly directed locking lugs 11.
  • the inner walls 15 of the elongated holes 10 in the plate 48 taper slightly in order to to lie smoothly on the tubes of the support frame 2 in the two possible positions.
  • Fig. 5 shows a plan view of the functional parts locking body 6 and seat support 8.
  • the upper plate 48 with the elongated holes 10 and the locking lugs 11 is partially cut away and gives a view of the lower plate 49 with the bore 16 for the tubes of the support frame .
  • the seat support 8 is mounted on the axis 12 between the legs 42 of the locking body 6. In the cut-open part it can be seen how the legs 43 of the seat support 8 extend rearward and rest with their tabs 26 on the locking axis 22, which in turn is connected to the rolling element 51, which in the locked position rest on the tubes of the support frame .
  • the locking means 14, which is designed as a thin rod and tilts laterally through the legs 42 of the locking body. Only the front edge of the handle part 9 can be seen.
  • a hole is made in the upper surface 52 of the seat support 8 approximately in the middle thereof, around which three inwardly curved grooves 29 are arranged at regular intervals. These grooves have depressions 41 in their center, from which they become evenly flatter on both sides.
  • the grooves 29 serve as bearings for balls 33.
  • the counterpart to this is the seat plate 30 of the seat body 5 shown in FIG. 6), on which the cushion 31 is attached.
  • the seat body 5 is inserted with the seat plate 30 downward onto the seat support 8, the threaded rod 34 passing through the bore 28.
  • the grooves 29 and 32 each form a housing for the balls 33 in pairs.
  • a disk 35, an axial ball bearing 36, a disk 37 are seen one after the other from the seat plate 30 and the upper surface 52 of the seat support 8 elastic element 38, e.g. a rubber ring, a washer 39 and a nut 40 are arranged.
  • the balls 33 can move a little in the narrowing grooves 29, 32, since the elastic element yields somewhat. If the seat body is released, it rests itself due to the elastic force and favors itself by the grooves sloping into its center. The weight of the person using it enables the seat body to be turned easily and comfortably.
