Definitions
- the invention relates to a wheelchair with a base body on which a seat and on the two drive wheels and at least one Rear wheel and two front wheels are arranged, with the front wheels each at least one rotatable about a horizontal axis, an abutment having pivot arm hinged to the body are and are from a basic position in a raised or a raised position lowered position are movable, with an upper stop to Limiting the pivoting movement of the pivot arm provided is.
- the front wheels When driving over an obstacle, the front wheels swivel above, whereby a spring is tensioned, which after passing over the Block the front wheels to their original position or basic position moved back. From this basic position, the front wheels can also be pivoted to a lowered position, for example a depression is passed through or a curb shut down.
- the swivel range upwards is through limited a stop which is arranged on the frame. Of the Stop can be by a frame member or a compression spring be formed.
- wheelchairs are known with a lifting device by means of which raised the seat and possibly also changed in its inclination can be.
- the lifting device enables the handicapped person to its seating position to the environment, especially in terms of Height, adjust, so that, for example, in the kitchen too Objects in wall cabinets or the like for the disabled be reached.
- By raising the seat is the Focus of the wheelchair also raised, resulting in a sloping ground can lead to a tilting moment.
- This task is solved with a wheelchair, in which between Body and seat a lifting device is provided and in the the upper stop with a moving component of the lifting device connected is.
- the invention is based on the recognition that a wheelchair over Swing-up front wheels has better obstacles to be able to overcome, not readily with a lifting device for the seat can be combined without the lifting device with the Pivotability of the front wheels is correlated. This correlation occurs above the upper stop, which with a moving component of Lifting device is connected.
- swipe range refers to the vertical movement the front wheels, which are independent of a vertical axis can be rotated.
- the swivel range of the front wheels is preferably not limited by a stop when retracted lifting device.
- a restriction of the pivoting range can be done, for example, by the spring force acting on the pivot arm return spring.
- retracted lifting device is thus a swivel range available, which is required in order to overcome the usual obstacles, such as curbs or the like, easily.
- the swivel range of the front wheels is defined by the upper stop.
- the pivoting range by the reduced to the lifting device coupled upper stop. at then fully extended lifting device is preferably no or only a small swivel range available.
- the upper stop can be so with the moving component of the Hub engaged connected and be designed such that at the beginning the extension of the lifting device, the pivoting of the Front wheels is completely prevented or the swivel range preferably continuously restricted until the maximum Lifting height is reached.
- the lifting device has a scissor joint.
- a lifter strut of the Scherengelenkes is connected to the upper stop.
- the lifting device has a lifting column
- the upper stop is on the moving component of the Lifting arranged that the upper stop at extended lifting device in a lower position (position B) and with the lifting device retracted in an upper position (position A) is located.
- Position B In the lower position (position B) is thus the pivoting range of Front wheels restricted accordingly, so that no longer the entire swing range is available.
- Position A In his upper Position (position A) is the top stop either as far above positioned that arranged on the pivot arm abutment no Contact or the top stop is outside the Movement path of the abutment arranged, so that thus the entire swing range is provided.
- the upper Stop in its lower position B spaced from the abutment arranged.
- the position of the front wheel becomes a flat floor surface understood in the case of extended even Lifting device is not the risk of tipping over.
- the upper stop in its lower position (position B) though small, yet spaced apart from the abutment, so that for the front wheels still a correspondingly small swivel range is available to drive over, for example, smaller obstacles to be able to.
- This is particularly beneficial in the home where For example, carpets or door sills are run over have to. Which pivoting range can be allowed depends on the design of the wheelchair and the maximum lifting height of the seat from.
- the upper stop comprises one on the base body pivotable pawl, on which one connected to the moving component Actuator attacks.
- This embodiment has the advantage that the stroke movement can be translated.
- One Gear ratio of 1.5 to 1 to 3 to 1, in particular from 2 to 1 is preferred.
- the translation also has the advantage of having the lifting device correspondingly large forces are exerted on the abutment can. This is necessary if, for example, the front wheels maximally swung and the operator in this State the lifting device would like to fully extend. This process could possibly cause the wheelchair to tip over, especially if the wheelchair is on a sloping floor surface is moved.
- the second upper stop comes early in contact with the abutment, so that on further booting the Abutment is pressed down.
- the pawl has a slot in which the free end the actuating element is guided displaceably.
- the latch preferably has at least one flat stop surface on.
- the pawl can also be designed as a cam and For example, have planar and curved stop surfaces.
- the abutment is an element with at least one flat abutment surface.
- the abutment can at least one or have a plurality of curved abutment surfaces.
- About the Arrangement and design of the stop surface and the Abutment surface and their mutual adaptation can vary depending on Type of wheelchair the desired positions are set.
- a wheelchair 1 is shown in side view.
- the wheelchair 1 has a base body 3, for example, a Framework can be.
- On the main body 3 are two drive wheels. 4 and corresponding drive motors 5 are arranged.
- Behind the Drive wheels 4 are in the embodiment shown here Rear wheels 6 rigidly attached to the base body 3.
- Front wheels 10 In front of the drive wheels 4 are front wheels 10, each on two pivot arms 11a, 11b are arranged pivotable about a horizontal axis, so that a pivoting movement in the direction of the arrow is possible.
- a lifting device 20 On the base body 3 is a lifting device 20, the one Scherengesch 21 has. On the lifting device 20 is the Seat 2, the raised by means of this lifting device 20 and possibly also can be changed in terms of its inclination.
- an upper stop 30 disposed with an abutment 12 on the pivot arm 11 interacts.
- the individual positions of the abutment 12 and the upper limit stop 30 can be associated explained in more detail with the following figures 2 to 6.
- FIG. 2 is a section of the wheelchair shown in FIG. 1 shown enlarged.
- the side view was on the drive wheel 4th and the front wheel 10 and the associated pivoting mechanism limited to better explain the details.
- the following explanations also apply to those on the arranged opposite side of the wheelchair wheels.
- This abutment 12 has a flat Abutment surface 13, which in the position I shown here with respect to Vertical is arranged inclined.
- the angled portion 14 of Abutment element 12 serves to stiffen.
- position I In the basic position shown here (position I), in which the front wheel 10 rests on the flat bottom surface 7, the abutment is 12th spaced from the upper stop 30 arranged.
- an actuator 40 is fixed, the order the fulcrum 41 is pivotally mounted.
- a connecting element 42 in the form of a Bolzens arranged, which engages in a slot 34 of a pawl 32, the forms the upper stop 30.
- the pawl 32 has on its underside a stop surface 33, which is also flat. Because the Lifting device in the representation shown here in the is retracted position, the pawl 32 is about the fulcrum 35th pivoted upwards, so that the abutment 12 is not with the pawl 32 can come into contact because the spring force of the tension spring 18, the is arranged between the base body 3 and the first pivot arm 11b, is chosen large accordingly. This position of the top stop 30 is referred to as position A.
- Fig. 3 the front wheel 10 is pivoted about the height H 2 .
- the lifting device is still in the retracted position.
- the position of the abutment 12 is referred to as position III.
- the position III is the maximum possible pivotal position of the front wheel 10, which is limited by the spring 18.
- the height H 2 is sufficient, for example, to drive over a curb.
- Fig. 4 starting from the Fig. 2, the lifting device is shown in the fully extended state.
- the lifter brace 22 is shown inclined, with the result that the actuator 40 is pivoted about the pivot point 41 down.
- the connecting element 42 in the slot 34 of the pawl 32 slides down and the pawl 32 about the pivot point 35 also pivots down so that the position B is occupied, whereby the pivoting range of the front wheel 10 is significantly reduced , This prevents the operator from passing over high obstacles when the lifting device is extended, which could lead to an overall unstable position of the wheelchair.
- the abutment 12 is in position I, because the front wheel 10 rests on the bottom surface 7.
- the two contact surfaces, ie the abutment surface 33 and the abutment surface 13 are extended by two lines, so that it can be seen that there is a distance D which allows a slight pivotal movement of the front wheel 10, as shown in FIG. For safety reasons, the lifting height is limited to H 1 .
- FIG. 6 shows a further embodiment in which the Lifting device 20 has a lifting column 23.
- the lifting column 23 is how in Fig. 7 can be seen more clearly, via a rocker 24, the one Fulcrum 25 has, connected to the actuating element 40, the as in the previously shown embodiments of the pawl 32 attacks.
- the Rocker 24 is guided in a slot 26 of the lifting column 23.
