Description

[0001] The invention relates to a wheelchair and a side panel for a wheelchair. Furthermore, the invention relates to the use of a side panel on a wheelchair.

[0002] Wheelchairs typically consist of a frame, two rear wheels spaced apart, and a seat located between the rear wheels. Wheelchairs are usually equipped with side panels. Side panels are primarily designed to prevent the wheelchair user's clothing from coming into contact with the rear wheels. They can also offer protection by reducing the risk of fingers getting caught in the spokes and becoming trapped.

[0003] Non-swivel and swivel side panels are known from the prior art. Non-swivel side panels can be permanently mounted to the wheelchair frame or designed as plug-in side panels. Swivel side panels are known, for example, from EP0827729A2 and DE19730717A1.

[0004] One disadvantage of conventional wheelchairs is that if changes are made to the rear wheels—for example, if the rear wheel mounting relative to the wheelchair frame is changed horizontally and / or vertically, or if the size of the rear wheel is changed—both the wheelchair's parking brake and the side panels must be repositioned so that these components are correctly aligned relative to the rear wheel. Such repositioning is relatively time-consuming.

[0005] Another disadvantage of conventional wheelchairs is that the attachment of the side panel and the parking brake must typically be located in a relatively small area of ​​the wheelchair frame. Due to the limited space, however, attaching the side panel and the parking brake is often difficult or not optimally possible, especially with wheelchair settings that have a low seat depth.

[0006] The invention is therefore based on the objective of providing an improved solution that addresses at least one of the aforementioned problems. In particular, it is an objective of the invention to provide a solution by which the effort required to assemble a wheelchair can be reduced and / or by which the assembly effort can be reduced in the event of modifications to the rear wheels.

[0007] According to a first aspect, the problem is solved by a wheelchair with the features of claim 1. According to this claim, a wheelchair, which can be designed in particular as a manual wheelchair, and preferably as a folding wheelchair, is provided. The wheelchair comprises a wheelchair frame, a first rear wheel comprising a first tire, and a second rear wheel comprising a second tire, wherein the first rear wheel and the second rear wheel are spaced apart from each other and are each connected to and rotatably mounted on the wheelchair frame.The wheelchair comprises a seat area, which is at least partially located between the first and second rear wheels, a first side panel, and a second side panel, wherein the first side panel is located immediately adjacent to the first rear wheel and at least partially on a side of the first rear wheel facing the seat area, and wherein the second side panel is located immediately adjacent to the second rear wheel and at least partially on a side of the second rear wheel facing the seat area. The wheelchair further comprises a parking brake, which is connected to the wheelchair frame by means of a frame connection device.

[0008] According to the invention, a receiving element is provided which is connected to the frame connection device and / or to the parking brake, wherein the first side part has a connecting section which is connected to the receiving element.

[0009] A wheelchair is therefore proposed with a first side panel connected to a mounting element. This mounting element is connected to the frame connection device and / or the parking brake.

[0010] A primary advantage of this type of wheelchair is that the parking brake and the first side panel can be connected to the wheelchair frame together using the frame connector. Only one frame connector is needed to attach both the first side panel and the parking brake to the corresponding frame tube of the wheelchair frame. This is advantageous because, compared to existing solutions, less installation space is required for connecting the parking brake and the side panel to the wheelchair frame. Therefore, less space is needed for attaching the parking brake and the side panel to the wheelchair frame.This provides the wheelchair user with a larger section of the corresponding frame tube to grip, especially for transferring into or out of the wheelchair, which can significantly facilitate the transfer.

[0011] Another advantage is that the parking brake and side panel can be adjusted together by sliding the frame connection device along the frame tube and fixing it in the desired new position. This makes adjusting the parking brake and side panel significantly faster compared to conventional wheelchairs. Furthermore, adjusting the parking brake and side panel together does not change their relative positions.

[0012] Another advantage is that the possibilities for changing the position of the side panel are improved by connecting it to the receiving element, since the receiving element can be designed in such a way that the side panel can be connected to the receiving element in different positions relative to the receiving element.

[0013] A manual wheelchair is understood to be, in particular, a wheelchair that is propelled by the user himself or by his or her companion, and is therefore not propelled by a motor.

[0014] A foldable wheelchair is specifically understood to be a wheelchair that can be folded into a transport position to make the wheelchair easier to transport.

[0015] The wheelchair frame preferably comprises several frame tubes, preferably an upper frame tube, a seat tube, a backrest tube and further frame tubes, wherein the frame tubes form the wheelchair frame.

[0016] A seating area is understood to be, in particular, the area in which the wheelchair user sits when using the wheelchair.

[0017] The parking brake is primarily used to lock the first rear wheel. A second parking brake may also be provided for locking the second rear wheel; this second brake may be designed similarly to the parking brake used to lock the first rear wheel.

[0018] It is particularly preferred that the receiving element is connected to the frame connection device. Preferably, the receiving element is also connected to the parking brake.

[0019] It is particularly preferred that the receiving element is arranged at a distance from the wheelchair frame, and preferably at a distance from an upper frame tube of the wheelchair frame.

[0020] Preferably, the first side panel is not directly connected to the wheelchair frame, but indirectly connected to the wheelchair frame via the receiving element.

[0021] Preferably, the first side panel is positioned at a distance from the wheelchair frame.

[0022] It is particularly preferred that the receiving element is essentially L-shaped.

[0023] It is particularly preferred that the receiving element has a first leg and a second leg, which are preferably arranged substantially perpendicular to each other, wherein the parking brake is connected to the first leg of the receiving element and the connecting section of the first side part is connected to the second leg of the receiving element.

[0024] Preferably, the receiving element can be connected to the frame connection device and / or the parking brake in various positions along the first leg. In this way, by changing the position of the receiving element—by moving it along the first leg to a different position and securing it in that position—the connected side panel can also be moved along with it and thus arranged in an optimal position.

[0025] Preferably, the frame connection device can be moved along the upper frame tube of the wheelchair frame and fixed in a desired position on the upper frame tube. This particularly advantageously allows the parking brake and the first side panel to be moved together relative to the first rear wheel, so that the position of the parking brake and the first side panel can be adjusted together by means of a single adjustment movement of the frame connection device along the upper frame tube. This results in a significantly simplified and faster adjustment of the first side panel and the parking brake relative to the wheelchair frame and relative to the first rear wheel.

[0026] It is particularly preferred that the first leg of the receiving element has an elongated hole extending along the first leg of the receiving element, through which at least one screw extends for connecting the parking brake to the frame connecting device.

[0027] By means of such an elongated hole, the position of the side panel can be changed in a particularly advantageous way relative to the parking brake.

[0028] Preferably, the screw for connecting the parking brake to the frame connection device extends through the parking brake and through the elongated hole extending along the first leg to the frame connection device.

[0029] In this way, the receiving element can be connected to the frame connection device and the parking brake in a particularly advantageous manner.

[0030] It is particularly preferred that the receiving element can be connected to the parking brake in a first mounting position and in a second mounting position.

[0031] Preferably, the receiving element is arranged rotated by 180° in the first mounting position compared to the second mounting position along the extension of the first leg.

[0032] Preferably, in the first assembly position, the first leg points substantially upwards in the vertical direction. Preferably, in the second assembly position, the first leg points substantially downwards in the vertical direction.

[0033] One advantage of these two mounting positions is that the first side panel can be adjusted vertically by switching between the first and second mounting positions.

[0034] It is particularly preferred that the parking brake has a pressure element which can be moved into a locking position for locking the first rear wheel, in which the pressure element rests against the first tire of the first rear wheel.

[0035] Preferably, the pressure element is movable between the locking position and a non-locking position, wherein the pressure element does not rest against the first tire of the first rear wheel in the non-locking position.

[0036] It is particularly preferred that the wheelchair frame has an upper frame tube which is arranged substantially parallel to a seat surface of the seating area of ​​the wheelchair, wherein the first leg of the receiving element extends parallel to the upper frame tube, and wherein preferably the second leg of the receiving element extends orthogonally to the upper frame tube.

[0037] By means of the legs of the receiving element extending in this way, the side panel and the parking brake can be adjusted relative to each other in a particularly advantageous manner in a direction parallel to the upper frame tube.

[0038] It is particularly preferred that the receiving element can be arranged in several positions in which, relative to each other, the receiving element is displaced along the extension direction of the first leg of the receiving element, and can be connected to the frame connection device and / or to the parking brake.

[0039] It is particularly preferred that the first leg of the receiving element has an elongated hole extending in the direction of extension of the first leg of the receiving element.

[0040] Preferably and particularly advantageously, the receiving element can be continuously adjusted relative to the parking brake due to the elongated hole extending along the first leg.

[0041] It is particularly preferred that the connecting section of the first side part can be arranged in several positions in which, relative to each other, the connecting section of the first side part is displaced along the extension direction of the second leg of the receiving element and can be connected to the receiving element.

[0042] It is particularly preferred that the second leg of the receiving element has an elongated hole extending in the direction of extension of the second leg of the receiving element.

[0043] Preferably and particularly advantageously, the receiving element can be adjusted steplessly in height, i.e., essentially steplessly in the vertical direction, due to the elongated hole extending along the second leg.

[0044] It is particularly preferred that the connecting section of the first side part is arc-shaped, and in particular as a rail-shaped section.

[0045] The connecting section can, in particular, be part of a guide rail that has a circular arc extension.

[0046] It is particularly preferred that the receiving element is detachably connected to the frame connection device, in particular by means of a screw connection.

[0047] It is particularly preferred that the receiving element is detachably connected to the parking brake, in particular by means of a screw connection.

[0048] Preferably, the receiving element is connected to the frame connection device and the parking brake by means of the same screw connection.

[0049] It is particularly preferred that the receiving element is arranged between the frame connection device and the parking brake, and is connected to the frame connection device and the parking brake, preferably by means of a screw connection extending from the parking brake through the receiving element to the frame connection device.

[0050] This allows for a particularly advantageous movement dependency between the mounting element, and thus the side panel, and the parking brake, since the mounting element and the parking brake move together when the frame connection device is moved. A further advantage is that only one screw connection is required to connect the parking brake and the mounting element, and thus the side panel.

[0051] It is particularly preferred that the connecting section of the first side part is designed in the form of a plug-in element which has a receiving section which is designed and arranged to receive a rail-shaped section of the first side part, wherein preferably the connecting section has two connecting elements for fastening the connecting section to the receiving element.

[0052] With such an embodiment of the connecting section in the form of a plug-in element, a particularly simple assembly and disassembly of the side part with the wheelchair can be achieved, since the side part can be pulled out of the connecting section and plugged into the connecting section in a relatively simple way.

[0053] It is particularly preferred that the first side part is detachably connected to the wheelchair frame, in particular to a backrest tube of the wheelchair frame, by means of a fastening element.

[0054] Preferably, the first side panel can be connected to the backrest tube of the wheelchair frame in different positions using the fastening element.

[0055] It is particularly preferred that the fastening element has a circular arc-shaped upper section, wherein a coupling element is arranged on the backrest tube, wherein the circular arc-shaped upper section of the fastening element interacts with the coupling element in such a way that the coupling element is moved along the circular arc-shaped upper section when the backrest tube is pivoted about a backrest tube axis.

[0056] The coupling element can, in particular, have a circular arc-shaped or round outer contour.

[0057] By means of such a coupling element and such a circular arc-shaped upper section of the fastening element, it is particularly advantageous to enable the backrest tube to rotate about a substantially horizontal axis. This allows for adjustability of the wheelchair's backrest.

[0058] It is particularly preferred that the circular upper section has a substantially U-shaped cross-section.

[0059] It is particularly preferred that the coupling element has a substantially circular outer circumference.

[0060] It is particularly preferred that the first side part comprises a side wall element with an outer contour, wherein the side wall element of the first side part is movable relative to the wheelchair frame between a working position and a non-working position along a circular arc such that the outer contour of the side wall element of the first side part essentially follows the outer circumference of the first rear wheel.

[0061] Such an outer contour of the side wall element of the first side part is to be understood in particular as the outer contour of the side wall element which extends radially outwards along the side wall element with respect to the radial direction of the first rear wheel.

[0062] The operating position refers in particular to the position of the side wall element in which the side wall element is arranged between the first rear wheel and the seating area, thereby providing protection from the first rear wheel for a user sitting in the seating area.

[0063] The non-use position refers in particular to the position of the side wall element in which the side wall element is arranged in a position that is moved backwards in relation to the direction of travel of the wheelchair compared to the use position.

[0064] It is particularly preferred that the side wall element of the first side part is displaceable along the arc of the circle between the operating position and the non-operating position.

[0065] One advantage of such a movable side panel element is that the first side panel is movable between a working position and a non-working position, and simultaneously, in every position—that is, in the working position, in the non-working position, and in all positions between the working and non-working positions—is arranged such that the outer contour of the side panel element of the first side panel follows the first rear wheel and is therefore directly adapted to the outer circumference of the first rear wheel in every position. This makes it particularly advantageous to ensure that the first side panel protrudes only minimally beyond the rear wheel in every position.This means the side panel restricts the wheelchair's freedom of movement far less than in conventional wheelchairs with movable side panels, where the side panel is significantly larger and extends much further from the rear wheel, thus considerably limiting the wheelchair's maneuverability. Another advantage is that the minimal overhang of the side panel relative to the rear wheel also reduces the amount of material required. This lowers the material costs for manufacturing the side panel. Furthermore, the weight of the side panel, and consequently the weight of the wheelchair, can be reduced.

[0066] It is particularly preferred that the side wall element of the first side part is displaceable along the arc of the circle between the operating position and the non-operating position.

[0067] Preferably, the side wall element of the first side part is movable between its operating position and its non-operating position by sliding the side wall element. An advantage of such movableness is that the side wall element can be moved along a precisely defined path.

[0068] Preferably, the side wall element of the first side panel is displaceable by means of a guide, particularly preferably along a guide rail. Such displaceability allows the side wall element to be supported not only at a single pivot point in the operating position, in the non-operating position, and in all positions in between, but also along a guide, and in particular along a section, in every position. This ensures that the side wall element has relatively little play in every position, thereby reducing or completely preventing rattling of the side panel and / or the side wall element, and increasing the stability of the side wall element.

[0069] It is particularly preferred that the first side part comprises a guide device which has a guide rail for guiding the side wall element of the first side part, wherein the side wall element of the first side part is connected to the guide rail and is movable, in particular displaceable, along the guide rail relative to the guide rail.

[0070] Preferably, the guide rail is designed in a circular arc shape at least in sections, and the side wall element of the first side part is movable, in particular displaceable, along the circular arc extension of the guide rail.

[0071] By means of such a guide device with a guide rail, a sliding function of the side wall element can be achieved in a particularly advantageous way, whereby the side wall element can then be moved along the guide rail.

[0072] It is particularly preferred that the outer contour of the side wall element is essentially arc-shaped and preferably adapted to the outer circumference of the first rear wheel.

[0073] It is particularly preferred that the side wall element of the first side part has a tire cover area that extends to the outer contour of the side wall element of the first side part.

[0074] Preferably, the side wall element has a tire cover area that extends radially outwards to the outer contour of the side wall element of the first side part.

[0075] Preferably, the tire cover area curves over the tire of the first rear wheel at least in sections, in order to cover the tire of the first rear wheel at least in sections, especially also from above.

[0076] One advantage of such a tire cover area is that it provides even better protection for the user from the front rear wheel. Furthermore, such a tire cover area improves splash protection.

[0077] It is particularly preferred that the second side panel, in relation to the second rear wheel, is designed in the same way as the first side panel, in relation to the first rear wheel.

[0078] Preferably, the second side panel is designed like the first side panel, but mirrored, so that it is arranged relative to the second rear wheel in the same way as the first side panel is arranged relative to the first rear wheel.

[0079] It is particularly preferred that the connecting section of the first side part is connected to the receiving element by means of a fastening device, preferably in the form of a fastening screw, and wherein the first side part is detachably connected to the wheelchair frame, in particular to a backrest tube of the wheelchair frame, by means of a fastening element.

[0080] According to another aspect, the aforementioned problem is solved by a method for positioning a side panel of a wheelchair, the method comprising: providing a wheelchair as described herein, releasing the connection between the frame connection device and the wheelchair frame, wherein the frame connection device is arranged in a first position relative to the wheelchair frame, moving the frame connection device along the upper frame tube of the wheelchair frame so that the frame connection device is arranged in a second position relative to the wheelchair frame, fixing the frame connection device with the upper frame tube of the wheelchair frame in the second position.

[0081] It is particularly preferred that the method comprises: moving the side wall element of the first side part from a position of use to a position of non-use by moving, preferably displacing, the first side wall element of the first side part along an arc of a circle such that the side wall element essentially follows the outer circumference of the first rear wheel with its outer contour.

[0082] It is particularly preferred that the method comprises: removing the side wall element from the wheelchair, in particular by lifting the side wall element in the non-use position, and preferably inserting the side wall element.

[0083] According to a further aspect, the aforementioned problem is solved by using a receiving element on a wheelchair, in particular a wheelchair as described here, wherein the receiving element has a first leg and a second leg which are arranged substantially perpendicular to each other, wherein a parking brake of the wheelchair is connected to the first leg of the receiving element, and wherein preferably a connecting section of the first side part is connected to the second leg of the receiving element.

[0084] For the advantages, design variants and design details of the various aspects of the solutions described here and their respective possible further developments, reference is also made to the description of the corresponding features, details and advantages of the other aspects and their further developments.

The second side panel 210 also has a side wall element 211 with a tire cover area 214, which has a radial outer contour 214a adapted to the outer circumference of the second rear wheel 270.The first side panel 10 and the second side panel 210 are essentially identical in design, but mirror-symmetrical, so that the first side panel 10 is adapted to the first rear wheel 70 and the second side panel 210 is adapted to the second rear wheel 270. An armrest 19a is detachably attached to the side wall element 11 of the first side panel 10. An armrest 219a is also attached to the side wall element 211 of the second side panel 210.

[0088] The side wall element 11 of the first side part 10 is in this in Fig. 1 first embodiment of the wheelchair 1 shown between the in Fig. The side wall element 11 of the first side part 10 is movable between the operating position shown and a non-operating position along a circular arc, such that the outer contour 14a of the side wall element 11 of the first side part 10 essentially follows the outer circumference of the first rear wheel 70. The side wall element 211 of the second side part 210 is movable between the operating position shown and a non-operating position along a circular arc, such that the outer contour 214a of the side wall element 211 of the second side part 210 essentially follows the outer circumference of the first rear wheel 270.

Fig. The wheelchair shown in point 1, therefore, the explanations regarding... Fig. 1 is referred to. In contrast to the one in Fig. The wheelchair shown in 1 indicates that it is in Fig. The wheelchair shown in point 2, however, has no armrests.

[0090] Fig. Figure 3 shows a side view of the in Fig. 2 wheelchair 1 shown with first rear wheel 70 shown partially transparently, wherein the side wall element 11 of the first side part 10 is arranged in the operating position. Also shown are the horizontal direction H, which here coincides with the direction of travel F, and the vertical direction V. The wheelchair frame has several frame tubes 90, 92, 85, 50, 40, 60, including an upper frame tube 40, a seat tube 50, a lower frame tube 60, and a backrest tube 92. The backrest tube 92 has a support section 90 and a push handle 91. The first rear wheel 70 has a tire 71, a rim 74, and spokes 75. The first rear wheel 70 is rotatably mounted about the wheel axis R1 on the wheelchair frame 5 by means of a wheel bearing 73 on a wheel mounting rail 72, which is connected to the lower frame tube 60 and the upper frame tube 40.

[0091] The side wall element 11 of the first side part 10 is located between the in Fig. The side wall element 11 of the first side part 10 is movable between the operating position shown in Figure 3 and a non-operating position along the arc 130, such that the outer contour 14a, which forms the radially outer contour of the tire cover area 14, essentially follows the outer circumference 70a of the first rear wheel 70 when moving between the operating position and the non-operating position. The side wall element 11 has an armrest receptacle 19 into which an armrest can be inserted.

[0092] In the first embodiment shown here, this movement capability of the side wall element is achieved by the first side part 10 comprising a guide device 13, which has a circular arc-shaped guide rail 13s for guiding the side wall element 11 of the first side part 10. The side wall element 11 of the first side part 10 is connected to the guide rail 13s and is movable relative to the guide rail 13s, i.e., it is displaceable along the guide rail 13s. The guide rail 13s has such a circular arc-shaped extension that the side wall element 11 is moved along the arc 130 when displaced along the guide rail 13s. The guide rail 13s extends from a first end 13a to a second end 13b along the arc 130.The guide rail 13s is indirectly connected to the wheelchair frame 5 in the area of ​​the first end 13a, which is designed as a connecting section V1, namely via a receiving element 20 (as in particular in connection with . Fig. 10). The guide rail 13s is also indirectly connected to the wheelchair frame 5 in the area of ​​the second end 13b, namely via a fastening element 18 (as described in particular in connection with Fig. 11 described).

[0093] Furthermore, a locking device 15 is provided which has a lever 16 (see, for example, Fig. 6a and Fig. 6b). By means of the locking device 15, the side wall element 11 can be locked in the operating position and released for movement into the non-operating position.

[0094] Furthermore, a parking brake 30 is provided, which is connected to the upper frame tube 40 of the wheelchair frame 5 by means of a frame connection device 35, 36. The parking brake 30 has a pressure element 33, which is connected to a pressure element holder 32, for locking the first rear wheel 70, which can be rotated about the axis R by means of a brake lever 31.

[0095] Fig. Figure 4 shows a side view of the object associated with Fig. 3 described wheelchair 1 with partially transparent first rear wheel 70, wherein the side wall element 11 is in the position shown here (in contrast to the one in Fig. 3 shown in the operating position) is arranged in the non-operating position. In the non-operating position, the side wall element 11 is arranged in a rearward position relative to the direction of travel F compared to the operating position.

[0096] Fig. 5 shows a side view of the item in connection with Fig. 3 and Fig. Wheelchair 1 described in Figure 4, with the first rear wheel 70 partially shown in transparent detail, whereby the side wall element has been completely removed and is therefore not shown.
