Definitions

  • the present invention relates to a mobile walking aid with an electric drive in a frame cross member and optionally with a handle unit which has a first handle and a second handle arranged distally in front of the first handle, the mobile walking aid being equipped with one, more preferably two such handle units.
  • Such a handle unit and such a mobile walking aid are from the EP 2 520 266 A1 known.
  • the US 2012/0328311 A1 describes a walking aid with two horizontally running longitudinal legs, which are connected to each other via a lower cross leg, from which three height-adjustable supports extend upwards, which are connected at their upper ends via an upper cross leg, from which two handlebars extend horizontally to the proximal end.
  • a vertical handle bar is arranged distally on each handle bar and lies between the upper cross leg and a handle located proximally on the horizontal handle bar.
  • the EP 2 145 569 A1 describes a bar with two wheels and two pairs of handles that protrude diametrically from the bar, a lower pair for a toddler and an upper pair for a supervisor, under whose guidance the toddler should learn to walk.
  • the CH 416.940 A. describes a walking aid with two horizontally arranged U-shaped frame parts, each consisting of three sections connected by joints and connected by three vertical supports, each of which carries a wheel.
  • Arranged inside the upper frame part are two handle units, each of which has a first handle that runs horizontally and transversely to the direction of travel, from which a second handle extends vertically upward.
  • the US 6,099,002 A describes a walking aid with two side parts, each having a horizontally extending longitudinal leg, of which two supports each extend upwards, which are connected to one another at their upper ends via a bracket which ends in a horizontally extending and proximally extending handle.
  • a small wheel is arranged distally on each longitudinal leg, while a wheel is arranged proximally, which is connected via a bracket to the proximal support and via a strut to the proximal end of the longitudinal leg.
  • the WO 2011/034427 A1 describes a wheelchair from which the backrest and a rear section of the seat can be removed to form a walking aid.
  • the walking aid formed in this way has two side parts, each of which comprises a horizontal upper leg, which merges distally into a vertical leg the lower end of which is arranged a wheel. Approximately halfway up, an arched downward and proximal support is attached to each vertical leg, each of which carries a wheel at its lower end. At the distal end of each upper leg, a height-adjustable handle is arranged, which extends horizontally and proximally.
  • the US 2,733,754 A describes a walking aid with two U-shaped side parts open at the bottom, each of which has two vertical legs, each of which is connected to one another via an upper leg and a central longitudinal strut and each carries a wheel at its lower ends.
  • the two distal legs are connected to each other via a scissor strut, the two proximal legs carry a seat board, which is attached to the central longitudinal struts by means of a height-adjustable bar.
  • the DE 20 2010 013 242 U1 describes a walking aid with two side parts, each having a horizontally extending longitudinal leg, from each of which a hinged support extends upwards, which end at their respective upper ends in a horizontally extending and proximally extending handle.
  • a wheel is arranged proximally and distally on each longitudinal leg, the distal wheel being foldably connected to the distal end of the longitudinal leg.
  • the supports and the two longitudinal legs are each connected to one another via their own scissor struts.
  • the DE 20 2011 101 334 U1 describes a walking aid with two side parts, each having a horizontally extending longitudinal leg, from each of which a hinged support extends upwards, each of which ends at its upper ends in a horizontally extending and proximally extending handle.
  • a wheel is arranged proximally and distally on each longitudinal leg.
  • the supports are connected to each other via a scissor stay so that the two side parts can be folded together. After the side parts have been folded up, the supports can be folded onto the longitudinal legs so that the walking aid can be folded up very compactly.
  • Mobile walking aids are generally used to enable older, sick or disabled people to move independently, who are not mobile or not sufficiently mobile without walking aids.
  • the walking aids also known as rollators, are used which have three or four wheels which are fastened to a frame on which corresponding handle units are provided.
  • the users support themselves on this handle unit and thus push the rollator in front of them when walking. In this way, the users get adequate safety when walking and standing.
  • the handle units generally include a handle that is designed like a rod and has, for example, the shape of a handle on a bicycle handlebar.
  • the handles in rollators are aligned with their longitudinal direction in the forward direction of the rollator.
  • EP 2 520 266 A1 describes a handle unit which, in addition to the first handle aligned in the longitudinal direction, has a second handle, which is arranged in the direction of travel of the rollator before the first handle.
  • This second handle is plate-shaped, so that the user can place his palm on this second handle and put his fingers around the round plate.
  • the second handle serves as an aid when standing, standing up or sitting down.
  • the second handle is often used even with a longer load to relieve the joints through the other hand position.
  • the second handle is wider than the first handle transversely to the direction of travel.
  • walkers and other mobile walking aids can be equipped with an electric drive, in order to make it easier to push a walker, which may still be loaded with shopping goods, particularly on slopes. Furthermore, walking aids of this type are often designed to be collapsible.
  • brake and locking levers are also provided on the known rollators, which are pivotally mounted distally on the handle unit.
  • the rollator is braked in the manner of a brake, while pressing the brake and locking lever results in the rollator being blocked permanently, even when the brake and locking lever is no longer actuated.
  • the brake and locking lever has a lower locking position in which it remains when pressed down.
  • the EP 2 520 266 A1 propose to bend the plate-like second handle upwards so that it protrudes upward over the longitudinally extending first handle.
  • the inventors of the present application have now recognized that the known handle unit causes problems in certain positions of use, in particular with regard to safety and convenience. Furthermore, the known walking aids are not safe and easy to use in all operating situations, and are easy to fold despite the electric drive.
  • the present invention is based on the object of developing a walking aid of the type mentioned at the outset in a structurally simple manner in such a way that it has greater safety for the user and ensures improved usability.
  • a mobile walking aid with two angled frame parts, each having a crossbeam with two wheels and a leg which stands distally on the crossbeam and on each of which a handle unit is arranged such that it can be adjusted in height, a collapsible scissor stay being arranged between the frame parts, a stiffening, removable frame is provided between the two legs, and an electric drive for a wheel mounted on the crossbar is provided in at least one of the crossbars.
  • This walking aid is particularly stable due to the double stiffening due to the scissor strut and frame, but it is still easy to fold up, for which purpose only the frame has to be removed and the scissor strut has to be unlocked.
  • the frame is locked with the legs, because then simply by releasing the locking, folding is particularly easy.
  • the frame is connected to a box, preferably a lid serving as a seat is foldably arranged on the frame, and further preferably the frame is rectangular with a distal and a proximal longitudinal spar and two transverse spars which form the longitudinal spars connect with each other, the cover preferably being pivotally mounted on the distal longitudinal spar.
  • connection cables preferably leading to the electric drive in the frame parts.
  • the advantage here is that, like the lines and cables of the brake system, all components for the electric drive are arranged within the frame parts or the box are so that the user cannot injure himself or get caught on it and possibly even fall. So these features also serve the safety of the user.
  • the left handle unit and the right handle unit are mirror-symmetrical, as it corresponds to the anatomy of the left and right hand.
  • the handle units are attached in a height-adjustable manner.
  • the second handle of the mobile walking aid is preferably designed as a rod-like handle, the first handle and the second handle being connected in a T-shape, the first handle preferably having a palm rest, and the second handle extending between an inner and an outer end face , the two end faces protruding laterally beyond the hand rest, so that the second handle extends between the end faces transversely to the first handle.
  • the combination of the first and the second handle now has a T-shape, the cross bar of the T, ie the second handle, being distal to the user.
  • distal and proximal are used in the manner customary in medical technology. Distal consequently means a position remote from the user, while proximally has a position pointing towards the user.
  • the handle unit thus has a proximal first handle and a second handle arranged transversely distally in front of the first handle.
  • the second handle is arranged transversely to the first handle, so it does not run upright but essentially horizontally in the use position of the handle unit.
  • the first and the second handle form a lying T in the use position
  • the hand of the user who has gripped and moved the walking aid on the first handle is protected from injury in the event of a collision with walls, doors and other objects.
  • the hand rest enables a comfortable grip and long-term hold of the first handle.
  • the rod-like second handle protects the hand even if it grips the second handle instead of the first while moving the walking aid, because the two side end faces protrude over the hand on the left and right and also provide collision protection.
  • the T-shaped arrangement of the first and second handles thus provides considerably better protection of the user's hands against injuries than is known from the prior art.
  • a rod-like handle is understood to mean an elongated handle in the manner of a bicycle handle, which can be fully gripped by the fingers and the thumb of a hand in the manner of a rod.
  • first handle has a first longitudinal axis and the second handle has a second longitudinal axis, the second longitudinal axis intersecting the first longitudinal axis on the side of the inner end face of the second handle at an angle which is between 80 ° and 60 °, is preferably between 75 ° and 65 °.
  • the handle unit has a longitudinal beam running below the first handle, which has a third longitudinal axis which, on the side of the inner end face of the second handle, intersects the first longitudinal axis at an angle which is between 5 ° and 15 °.
  • the lower side member is advantageous from a safety point of view because it is used to attach the handle unit to the walking aid and is oriented in the direction of travel.
  • the first and second handles are rotated out of the aligned or exactly transverse orientation with respect to the direction of travel, which corresponds to the third longitudinal axis.
  • This measure thus forces the hand of the user who has gripped the first handle or handles to be slightly tilted outwards on the wrist, so that when driving the hand is not bent as far as is the case with handles oriented in the direction of travel.
  • the second handle can be used when the user is standing for a long time, for example when shopping, or wants to grip the walking aid not on the first but on the second handle when walking.
  • Both the pivoting of the first handle and the pivoting of the second handle thus serve the safety of the user, because this prevents the feeling of numbness from occurring in areas of the hand that would impair the use of the walking aid.
  • first handle and the second handle have the shape of a lying T in the use position, they are not associated with the problems that arise with the handle unit from the EP 2 520 266 A1 result.
  • a cheek is arranged on the side member, by means of which the height of the handle unit can be fixed to the walking aid.
  • This measure also serves safety, because the handle unit can be optimally adjusted in height depending on the stature of the user and depending on the state of health.
  • the handle unit has a self-contained frame that connects the first handle, the longitudinal member, a proximal, proximally curved section that connects the longitudinal member with its proximal end to a proximal end of the first handle distal, has laterally outwardly pivoted section which connects the longitudinal beam at its distal end to the outer end face of the second handle.
  • first handle and the second handle are very securely connected to the side member, by means of which the handle unit is attached to the walking aid in a height-adjustable manner.
  • the proximal and distal support of the first handle on the side member prevents the handle from bending or even springing away when the load is too great. This bending or springing can cause the walking aid to be pushed away or even lifted off the surface, which is associated with a corresponding risk of falling.
  • the pivoted distal section of the closed frame acts as a kind of side bumper, which protects the palm of the hand when gripping the first handle and the edge of the hand in the area of the little finger against collisions when gripping the second handle.
  • the handle unit has a pivotably mounted brake and locking lever, which is arranged under the first handle and extends with its free distal end to the second handle.
  • the brake and locking lever offers the safety function already mentioned at the beginning, the free end here not being arranged proximally, as in the prior art, but distally.
  • This arrangement offers further safety for the user, because, for example, when he stumbles forward, he automatically comes forward with his hand to the free distal end of the brake and locking lever, so that it arrives reliably in the locking position.
  • the new way of arranging the brake and locking lever thus increases the safety that the new handle unit of a mobile walking aid conveys.
  • the brake lever is pivotally mounted on the proximal, curved section of the frame.
  • the storage on this part of the frame enables all cables and lines from the brake and locking lever to run inside the frame to the cheek and from there in the frame parts of the walking aid.
  • cables and lines are not on the outside of parts of the walking aid, which also increases safety, since no jamming or jamming in these cables and lines is possible.
  • the brake lever has an oval grip hole.
  • This stop prevents in a structurally simple manner that fingers or thumbs can become trapped between the brake and locking lever and the first handle when braking.
  • an inner, broadened support surface for the ball of the thumb is provided on the hand rest of the first handle.
  • This measure has the advantage that the thumb rest forces the hand on the wrist to be pivoted into a position in which the carpal tunnel is prevented from being pinched off.
  • the frame is formed in one piece, the frame and the second handle preferably being formed in one piece with one another.
  • the safety aspect is also increased, because parts that are formed in one piece with one another do not form any edges or undercuts on which users could injure themselves or get caught with items of clothing.
  • parts of the handles be provided with cushions to cushion them or even to individualize them visually.
  • the handle unit has at least one control element for an electric drive of the walking aid, at least one control element being arranged on the inner end face of the second handle and / or one control element below the first handle on an inner thumb rest.
  • a control element can be a recognition element that recognizes and reports to a control system that a hand rests on the handle in question.
  • This measure has the advantage that the control elements for the electric drive are located where the thumb of the respective hand is in a relaxed position, namely either on the inner face of the second handle or below the palm rest of the first handle on one there provided thumb rest, which can also be designed as a stop for the brake and locking lever.
  • stop and the thumb rest can be formed by a single element because of the free distal end of the brake and locking lever.
  • the detection elements can be designed as microswitches or capacitive sensors, which are connected to a control system in such a way that the electric drive can only be started when both hands rest on the handles, so that a detection element detects and reports the adjacent hand on each handle. This also serves the safety of the user, because an unintentional starting of the walking aid is prevented.
  • Fig. 1 10 schematically shows a mobile walking aid which has two angled frame parts 11 and 12, each of which has the shape of a boomerang. Between the frame parts is a box 13 with an in Fig. 1 Frame not shown arranged that connects the two frame parts 11, 12 so that they are fixed and stiffened parallel to each other.
  • Each frame part 11, 12 has a lower cross member 14 or 15 (see 6 to 10 ) as well as distally on the traverse on a raised leg 16 or 17 which is slightly inclined proximally.

  • a handle unit 18 or 19 is arranged at the top of the upstanding legs 16 and 17, respectively. Electric drives and controls can be arranged in the traverses 14, 15, as will be explained below.
  • a pivotable lid 20 is provided on the frame, which closes the box 13 and at the same time serves as a seat on which the user can sit to rest.
  • the box 13 is designed as a bag or box and serves the user as storage space for shopping and / or usual utensils that he / she carries with him.
  • the box is used to hold a battery pack when the walking aid 10 is equipped with electric drives.
  • the center of gravity of the walking aid is shifted distally, which in particular ensures even greater stability when the user also uses the walking aid 10 as an aid when getting up.
  • the walking aid 10 is in Fig. 1 moved to the left in the direction of travel 21 by a user gripping the grip units 18 or 19 with his right or left hand.

  • the frame 72 serves as a support for the cover 20, which is articulated on the distal longitudinal spar 73; this is in Fig. 8 to recognize the walking aid 10 in a representation as in Fig. 6 shows.
  • a recessed grip 78 is provided on the proximal longitudinal spar 74.
  • the cover 20 is consequently opened upward in the distal direction, so that it offers protection against theft towards the front, ie distally, and allows easy access through the frame 72 for the user standing between the cross members 14, 15.
  • a small parts box for keys, wallet, papers, small change etc. can now be arranged under the frame 72, for example.
  • the walking aid 10 is thus equipped with a seat and possibly a small container for small parts.
  • the box 13 comes out Fig. 1 for use.
  • the box 13 is firmly connected to the frame 72, which in Fig. 1 is indicated.
  • the box 13 is then made together with the frame 72 between the frame parts 11, 12 Fig. 6 used, the frame is used again for stiffening.
  • bulges 81, 82 can be seen on the inner sides 68, 69 in the proximal area of the traverses 14, 15, in which bulges are arranged, each of which comprises an electric motor 83 with control and an angular gear 84, as is indicated in dashed lines for the bulge 81.
  • the angular gears 84 are connected to the wheels 24, 25, which accordingly drive them when the electric motors 83 are energized, when the control elements 58, 59 are actuated, and at the same time both hands rest on the detection elements 53, as described above.
  • the batteries for operating the electric motors 83 are arranged in the box 13. Connecting cables 85 between the control elements 58, 59, the battery pack and the electric motors 83 run inside the frame parts 11, 12 and are therefore not recognizable in the figures and in Fig. 8 indicated by dashed lines in the frame part 11.
  • 24 volt direct current motors are used as electric motors 83, the angular gears having a transmission ratio that makes it possible for the walking aid to be easily pushed when electric motors 83 are de-energized.
  • a suitable plug is inserted into the charging socket 87, which has a magnetic lock, which only connects the contacts 88 of the charging socket 87 with the battery pack 86 when the plug is inserted. This also serves the safety of the user, since the contacts 88 are not connected to the battery pack 86, that is to say they are de-energized as long as no plug is inserted.
  • Fig. 8 two insertion openings 89, 90 can still be seen in the upstanding legs 16, 17, into which the cheeks 54 of the handle units 18 and 19 are inserted, adjustable in height, and appropriately locked.
  • the frame parts 11, 12 can be moved towards one another parallel to one another, the struts 62, 63 pivoting about the pivot point 60.
  • the upper ends 91, 92 of the struts 62, 63 pivot on the articulated levers 65, 66 relative to the frame parts 11, 12 until finally the position of the Fig. 10 is achieved.
