Definitions

  • the invention relates to a standing aid with the features of the preamble of claim 1.
  • DE-A-82 20 630 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 because 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-A-84 16 541, 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.
  • 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.
  • a version with a height adjustment of the seat body by a gas spring is also known.
  • this standing aid is relatively complex and also does not offer the comfort of a lateral rotation of the seat body.
  • US-A-4,738,487 shows a standing aid consisting of a base frame, a support frame connected to it, and a seat support fastened to the support frame and a seat body arranged on this seat support.
  • the support frame has a latching body which is displaceable along the support frame and has latching holes which can be brought into engagement with latching lugs so that the seat support is locked in various positions.
  • FR-A-2 394 304 shows a standing aid consisting of a base frame, a support frame made of two tubes connected to it, and a seat support attached to the support frame and one on this seat support arranged seat body, wherein the seat support with the seat body is adjustable in height along the support frame.
  • the seat body is pivotally attached to the seat support.
  • the object of the present invention is to provide a standing aid which is easy to use, offers sufficient security when locking the height adjustment, has an inclinable seat body and dispenses with elaborate 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 between two legs projecting forward a locking body slidable along the support frame is pivotally mounted and lockable in various positions.
  • the locking body can be brought into engagement with locking lugs with locking holes in the support frame and can be released again.
  • the seat support is U-shaped, designed with legs directed downwards and mounted on an axis arranged in the upper region between the legs of the latching body, the axis reaching through elongated holes arranged in the legs and pointing upward and thus movement of the seat carrier along these Elongated holes allowed.
  • the legs of the seat support have adjusting notches in their lower area, which can be engaged or disengaged again according to 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 axis 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 latching body lies in this recess, with a first position of the axis leaving the control curve and a second position by lifting 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 of the seat support between the legs of the locking 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 locking 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 has guide holes with little play for the support frame and the upper plate has elongated holes for the support frame, in the elongated holes after internally facing locking lugs are arranged such that they engage in the locking holes provided on the side of the support frame opposite the seat support when the locking body is in a first position in contact with the rear side of the elongated holes and that the locking lugs do not engage in the locking holes, when the latching body is in a second position lying against the elongated holes at the front, the latching 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 support 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 away from the locking axis that this can assume a front position in the elongated holes, the locking lugs then coming out of engagement with the locking holes by a pivoting movement of the locking body.
  • the locking axis is provided in the area in which it rests on the support frame with the shape of the support body adapted to the support body and is biased 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 securely locked in its position and additionally secured by the bolt axis.
  • Fig. 1 discloses a standing aid 1 according to the invention, consisting of a base frame 3 with non-slip feet 4 and an attached, with lighter Inclination to base frame 3 emerging support frame 2.
  • 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 which 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, is suspended 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.
  • 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 to 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.
  • a pair of the notches 17 of the legs 43 of the seat carrier 8 lying opposite one another lie on the thin rod serving as locking means 14, which is mounted in the legs 42 of the locking body 6.
  • 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 setting 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 carrier as an obliquely upward elongated hole 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 causes 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 swiveling range. If the locking axis is released, ie it can move forward in the elongated hole 21, the latching body 6 in the elongated hole 10 in the upper plate 48 can be tilted upwards and backwards so far that the latching lugs 11 are out of engagement with the support frame 2 come and the locking body 6 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 latching lugs 11 of the latching body 6 and latching holes 7 of the support frame meet.
  • FIG. 4 shows a top view of the upper plate 48 of the latching body 6 with the legs 42 projecting forward and the elongated holes 10 with the latching lugs 11 directed inwards.
  • 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.
