Definitions

  • the invention relates to a pivoting legrest, in particular for wheelchairs, with a calf plate which is attached via a hinge to the legrest and which is pivotable from a support position A in a first front rest position B.
  • the invention also relates to a wheelchair with legrests.
  • Wheelchairs usually have two side-mounted legrests, at the lower end of each footrest is attached. These legrests may be pivotally mounted to facilitate entry and exit of the person or to bring the legrest into a horizontal position.
  • calf plates are provided on the leg supports on which the lower leg of the patient rests.
  • legrests known, to each of which a calf plate and a foot plate is attached.
  • the leg support is intended to allow easy entry and exit, which is achieved by the fact that the legrest is pivotable about both a horizontal and a vertical axis and can be disassembled if necessary.
  • the leg support is made of telescopic tubes, so that it can be extended when pivoting and can be shortened when swinging.
  • the calf plate is on Fixed leg support and can thus only be moved together with the entire legrest.
  • calf plates which are attached via a hinge to the legrest and can be pivoted from a support position to a front rest position.
  • the support position designates the position of the calf plate in which it can exercise its support function, ie, in the support position, the lower leg rests with the calf on the calf plate.
  • the calf plate or the hinge rests against a stop, so that no special fixing or locking device is provided.
  • the front rest position refers to a pivoted forward in the direction of travel of the wheelchair position of the calf plate, in which it is folded into the legrest.
  • a lateral pivoting away of the legrest simultaneously causes a pivoting movement of the calf plate, with the result that the leg of the wheelchair occupant is twisted.
  • a lateral pivoting of the legrest is therefore only possible if the leg of the wheelchair occupant located in front of the calf plate has previously been removed from the pivoting area of the calf plate.
  • legrest in which the hinge is a detent hinge, which locks the calf plate in its supporting position A in the locking position and which permits pivoting of the calf plate from the supporting position A into a second, rear, resting position C.
  • the invention is based on the recognition that the calf plate must release the leg of the patient when pivoting the legrest, without this having to lift his leg or otherwise move.
  • the release of the leg is made possible by a novel attachment of the calf plate to the leg support, which not only pivots the calf plate forward but also folds back, i. a pivoting of the calf plate - seen in the direction of travel - allowed to the rear.
  • the locking hinge has a 180 ° pivoting range with a central detent position.
  • the support position A is the calf plate in a position which is aligned substantially perpendicular to the direction of travel.
  • the calf plate is aligned substantially parallel to the direction of travel, wherein the calf plate in the first rest position B faces forward and in the second rest position C points to the rear.
  • the latching hinge preferably has a first hinge part fastened to a support tube of the legrest and a second hinge part fastened to the calf plate, wherein in the support position A the hinge axis is arranged between the calf plate and the support tube.
  • a correspondingly large pivoting range is accessible in order to be able to pivot the calf plate both forward and backward. It has proven to be advantageous if the distance between the hinge axis and the calf plate is less than the distance between the hinge axis and the support tube.
  • the calf plate is slidably disposed in the direction of the hinge axis.
  • the calf plate in the locking hinge is displaced downwards.
  • a special operating mechanism is not required because only the calf plate must be detected by the wheelchair occupant and must be pressed down.
  • a slight pivoting movement of the calf plate is still required to come out of the detent position and thereby prevent snapping back into the detent position.
  • the latching hinge preferably has a spring which moves the latching hinge into the latching position.
  • the locking hinge has locking means which may comprise a locking pin and a locking cone with a central recess for receiving the locking pin.
  • the spring is arranged such that the locking pin engages in the locking position in this central recess and thus fixes the hinge and thus the calf plate in the supporting position.
  • To release the calf plate from the supporting position it is possible by the movement of the calf plate to remove the locking pin from the recess of the locking cone, so that the two hinge parts of the locking hinge are freely movable to each other.
  • the first hinge part is U-shaped and has a hinge pin on which the second hinge part is pivotally and slidably mounted.
  • the locking hinge is mounted perpendicular to the hinge axis adjustable on the legrest. This makes it possible to adjust the position of the calf plate according to the requirements of the patient.
  • the locking hinge is connected via a mounting plate with the legrest, so that different positions can be adjusted.
  • This mounting plate can be, for example, a perforated plate.
  • the calf plate is mounted perpendicular to the hinge axis adjustable on the locking hinge.
  • the subject of the invention is also a wheelchair with two pivoting legrests, each legrest being provided with a calf plate which is fastened to the legrest via a hinge and which is pivotable from a support position A into a first rest position B.
  • These leg supports each have a detent hinge, which locks the calf plate in its supporting position in the locking position and which permits pivoting of the calf plate from the supporting position A into a second rear rest position C.
  • a wheelchair 1 which has a seat 2, rear wheels 3 and a frame 4.
  • legrest 10 is pivotally mounted on both sides. The pivoting of the legrests 10 is shown for the left legrest.
  • Each leg support 10 has a support tube 11, at the lower end of a footrest 12 and in the central region a calf plate 20 is attached via a latching hinge 30.
  • the locking hinge 30, which will be explained in detail in connection with the following figures, is formed during pivoting of the legrest 10, as shown for the left leg support, such that at the same time pivoting back of the calf plate 20 from the support position A in the rear rest position C is possible. In this rest position C, the leg of the person sitting on the wheelchair (not shown) is released, so that the legrest can be easily pivoted and the patient can get out of the wheelchair 1.
  • the plan view is shown from the front on a calf plate 20 which is attached via the latching hinge 30 to a mounting plate 13 of the support tube 11.
  • the detent hinge 30 has a first hinge part 32 which is fixed to the mounting plate 13 and a second hinge part 40 which is connected to the calf plate 20.
  • FIG. 3 shows the plan view from above of the calf plate shown in FIG. 2.
  • the latching hinge 30 has a hinge pin 39 which defines the hinge axis 31. It can be seen in FIG. 3 that the hinge axis 31 is located between the two planes 24 and 25 of the calf plate 20 associated with the front side 21 and the rear side 22, wherein the distance between the hinge axis 31 and the outer edge of the calf plate 20 is less than that Due to this arrangement of the hinge axis 31, a corresponding distance to the support tube 11 is ensured and a corresponding space for pivoting the calf plate 20 is provided.
  • the latching hinge 30 is fixed with its second hinge part 40 to a mounting plate 23 on the back 22 of the calf plate 20, via which the distance of the calf plate 20 to the support tube 11 can be adjusted.
  • a arranged at the upper end of the support tube 11 handle 14 is shown, which covers the support tube 11.
  • a push button 15 In the middle region of the handle 14 is a push button 15 to see a manual override, by means of which the legrest can be released from its locked position and pivoted.
  • Fig. 5 the position C is shown, showing the second rear rest position of the calf plate 20. In this position, a pivoting of the legrest 10 is possible without the calf plate 20 obstructing the relevant leg of the wheelchair occupant. By folding back to the position C, the leg is released and the legrest 10 can be easily pivoted.
  • the first hinge part 32 is U-shaped and consists of a connecting web 33 with the two legs 34 and 35.
  • the second hinge part 40 is fixed to the calf plate 20 and slidably mounted in the hinge pin 39 of the first hinge part 32 in the arrow direction.
  • the locking hinge In the position shown in Fig. 6, the locking hinge is in the locking position in which the second hinge part 40 is in its upper position. In this position, the second hinge part 40 is pressed by means of the spring 38, which is arranged on the hinge pin 39 and acts on the underside of the second hinge part 40.
  • the first hinge part 32 has on the underside 37 of the upper leg 34 a locking pin 36, which is only hinted at in FIG. 6, because it engages in the detent position shown here in the recess 43 of the locking cone 42, which is arranged at the top of the projection 41.
  • the calf plate 20 is in the supporting position A.
  • the second hinge part 40 is pivotable about the detent pin 39, so that by pivoting the calf plate 20, the second rear rest position C of the calf plate 20 can be taken.
