Definitions

  • the invention relates to a device for adjustment the camber of vehicles, especially wheelchairs, or on a wheelchair with such a device.
  • the invention has for its object a device to adjust the camber of wheelchairs, which with a simple structure and simple, safe handling the adjustment of the Lintel allows.
  • the object is achieved by a device for Adjustment of the camber of wheelchairs solved, in which assigned a wheel axle to each wheel which is changeable in a position attached to a frame Axle mount is mounted, the wheel axis relative is pivotable to the axis.
  • the device according to the invention or with this device wheelchairs are characterized by a row significant benefits.
  • the device according to the invention thus enables simple and safe adjustment of the camber, so that in particular set a relatively large negative camber angle can be. This improves the ergonomics of the Using the wheelchair and increasing its maneuverability. Consequently is the wheelchair especially in sports where it is on fast rotating movement arrives, such as in ball sports, particularly well applicable.
  • the invention Wheelchair can be used without tools and without Adding or removing additional parts in an everyday position are brought, in which a relatively small Wheel camber angle due to the resulting overall width of the Wheelchair is desired.
  • the Axis adjustment on a circular path As a result, the upper area of the wheel in all settings of the camber a substantially constant distance from Frame of the wheelchair. It can be beneficial if the center of this circular path through the upper area of the wheel, for example through the upper tangential point of the wheel is formed. With this configuration the Both the distance of the upper area of the circular path remain Wheel from the frame as well as the height of the upper tangential point relative to the frame the same. Should, depending from the respective construction, the height of the frame change relative to the footprint, however, if necessary a toe angle correction of the drive wheels necessary.
  • the adjustment is also possible not on a circular path, but on any one Trajectory, for example an ellipse or any other spatial trajectory.
  • the height of the frame, based on a Footprint of the wheelchair in all settings of the Wheelchair is essentially the same.
  • the pivoting of the wheel axle provided according to the invention can be done in different ways, it is possible to store them in a guide in the axle mount, it can be with an area in a socket and with their other area in a cam-shaped guide groove be stored, it is also possible to use linear guide grooves or a gear arrangement, for example with Pry to use.
  • the device according to the invention can both be designed so that the height of the frame of the wheelchair in the camber adjustment remains the same or that a change in the height of the frame results. At a constant height of the frame occur no or only very low tracking errors, so that compensation of the same is not required.
  • the Height of the frame when changing the camber may be necessary measures to prevent tracking errors or at least to compensate.
  • the pivoting of the wheel axle is carried out to an appropriate extent.
  • backdrop guides can therefore both in a vertical as well as in a horizontal Level can be provided for adjustment.
  • a releasable locking device formed on the axle receptacle for gradual adjustment of the camber.
  • a such gradual adjustment is particularly so an advantage because the camber of both wheels is the same should be set. With a stepless adjustment there is a risk that the two wheels one have different camber.
  • the detachable locking device thus allows adjustment in individual Levels that can be easily checked visually.
  • the locking device comprises at least one longitudinally displaceable bolt, which in one of several recesses of the wheel axle and / or the axle holder can be inserted.
  • the adjustment done without additional tools, no need to great forces are applied.
  • the bolt is easy to check that the desired setting is fixed.
  • the camber can be in one wide range can be adjusted, practically between 3 ° and 11 °. However, there are other angles possible in addition to any intermediate levels.
  • FIG. 1 and 2 show an embodiment in the rear view of a wheelchair according to the invention, this has two rear wheels 1, each on a wheel axle 2 are rotatably mounted.
  • a hand rim 14 is attached to each wheel 1 Design of the wheels 1, the push rims 14 and the Bearing, not shown, for rotatable mounting of the wheels 1 the fixed wheel axles correspond to the state of the art, so that there is no description in this regard can be.
  • the wheelchair also has a schematically shown Frame 3 on which an axle mount 4 is attached which is in turn adjustable the already mentioned wheel axles 2 stores.
  • 1 and 2 is a Seat 15 and a backrest 16 shown.
  • Fig. 1 shows the setting of the wheels 1 with a small Lintel angle
  • Fig. 2 is an adjustment with a large camber angle shows. 1 is thus a normal position shown
  • Fig. 2 a Sports position shows.
  • FIGS. 1 and 2 shows that the axle holder 4th each has a constant height H, regardless of the respective camber adjustment and that the lateral distance A of the upper areas 5 of the wheels 1 of the wheelchair always stays the same.
  • the different wheelbases are indicated by R.
  • FIG 3 and 4 show a first embodiment of the Axle holder according to the invention and the adjustment option for the wheel axle 2.
  • the axle holder 4 comprises a horizontally arranged tube (bracket) attached to frame 3 (see also FIG. 5 and 6).
  • the tube is on the side as protection against contamination limited by a cap 17, this is with a slot-like Provide opening 18 through which the wheel axle 2 extends from the interior of the axle holder 4.
  • the adjusting device has two link elements 19 (see FIGS. 7 and 8), which on the tube of the axle holder 4th are attached.
  • the backdrop elements each have one part-circular outer cross-section and are on their Flat inside.
  • the two backdrop elements are at an angle with two linear guide grooves 8, 9 arranged in relation to one another provided (see Fig. 7). Slides in the guide grooves 8, 9 slidably a sliding projection 20 of a bearing pin 21 (see Fig. 12), which in turn through a recess 22 of the wheel axle 2 (Fig. 9) is performed. It follows that two Bearing bolts 21 are provided which are rotatable in the two Recesses 22 of the wheel axle 2 are received and their Sliding lugs 20 are displaceable in the respective guide grooves 8, 9 are led.
  • the wheel axle 2 includes one cylindrical bearing part (left half of Fig. 9 and 11), and one with a square cross section Head area, which, as shown in Fig. 11, fork-shaped is formed and is provided with a groove 23.
  • a substantially cylindrical Approach 24 of an adjusting element 25 added in the groove 23 of the wheel axle 2 is a substantially cylindrical Approach 24 of an adjusting element 25 added.
  • This has an elongated hole 26, which from the one bearing pin 21 is reached.
  • the adjusting element 25 has a corresponding circular arc Outer contour so that it fits snugly and slidably is guided in the tube of the axle holder 4.
  • the head region of the adjusting element 25 has a recess 27 provided in which a spring 28 and two lateral bolts 10 are arranged (see Fig. 3).
  • Bolts 10 each have a head 29, which is a smaller one Has outer diameter than the bolt 10.
  • the two Bolts 10 are biased by the spring 28 and against pressed the inner wall of the tubular axle holder 4.
  • the axle holder 4 has a plurality of recesses 12 (FIGS. 3 and 5) into which the heads 29 of the bolts 10 can each snap into place.
  • 16 to 18 show a further embodiment.
  • This also has a tubular axle holder 4 provided which, however, pivotally supports a socket 6.
  • the socket 6 has a recess for receiving the cylindrical Provided part of the wheel axle 2, it has lateral Bearing pin 31, by means of which they in two lateral Bearing elements 30 is pivotally guided.
  • journal 31 In one of the journals 31 is displaceable by means of a Spring 32 biased pin 11 arranged, which in one of several recesses 13 of the wheel axle 2 can be latched is.
  • the rear end of the wheel axle 2 is with a bearing pin 33 provided, which has lateral sliding lugs 34, which in an arcuate guide groove 7 are mounted.
  • the invention Device can also be retrofitted to existing wheelchairs is because the frame of the wheelchair is for the device cannot be customized.
  • the length of the axle mount can vary wide wheelchairs can be adapted. It is understood that instead a single axle holder also two from each other independent, side axle mounts, which according to the invention are designed to be attached to a frame can.
