Definitions

  • the invention relates to a pushing device for use as an assistant or for transporting a load.
  • pushing devices used as assistants are often also referred to as rollators.
  • the sliding device is also generally regarded as a vehicle, with the longitudinal direction of the vehicle being the x-direction in relation to the main travel direction F, the transverse direction of the vehicle being the y-direction and the vertical direction of the vehicle oriented in the direction of gravity g being the z- direction is indicated.
  • Sliding devices are usually used to support mainly older people who are still mobile but need a stabilizing walking aid.
  • many pushers or rollators also provide the opportunity to sit down on a seat and rest there while sitting.
  • baskets, nets or other containers to transport objects and other loads, such as purchases, without the body of the person (user) using the sliding device being subjected to any significant additional stress. In particular, the user's arms and joints are relieved.
  • the front wheels are also slightly larger than the rear wheels.
  • the larger the radius of the front wheels the easier it is to overcome smaller obstacles such as doorsteps, curbs or curbs. Since curbs are often 10 cm to 15 cm high (high curb), the radius of the front wheels is usually smaller than such curb heights.
  • most rollators known from practice have to be tilted manually to get over the curb. In the state of tilting, vertical loads of the user cannot be absorbed or only with a considerable risk of falling, because the sliding device has to be balanced.
  • the basic idea of the invention is to make it easier for a person using a pushing device (i.e. a user) to overcome obstacles by enabling the front wheels to be raised intuitively and with little effort.
  • the user should preferably be able to be stabilized by the sliding device, even during lifting.
  • a pushing device with a drive device is in DE 10 2016 201 792 A1 described.
  • This pushing device has a device for using the driving device in such a way that by controlling the speed of the rear wheels a tilting angle can be created in order to negotiate steps or other obstacles.
  • a tipping aid for walkers which has at least one lifting arm with an end that can be attached to the walker and a ground contact end, the lifting arm being dimensioned such that its ground contact end can be pivoted between at least one rest position and one working position when the tipping aid is mounted on a walker as intended /or is movable, with the ground contact end in the working position touching the ground in front of or below the front wheels of the rollator and the lifting arm lifting the front wheels off the ground.
  • a gas damper lifting system for rollators or strollers which is mounted behind the front wheels of the rollator or stroller.
  • the gas damper lifting system makes it possible to raise the front wheels to overcome a step or other obstacle and to move the rollator or stroller further by pivoting the gas damper system around a joint until the front rollers touch down on the higher step level and the rollator or stroller continues to roll over the front rollers can.
  • a rollator with a swiveling front frame is known, the front wheels of which block when an obstacle is reached, such as a step, and leads to a swiveling of the front frame against the running direction in the direction of the rear frame.
  • One or more spring elements are compressed in the process. The energy stored in the spring elements then counteracts the swiveling in and pushes the front frame back in the direction of travel when the walker is pulled backwards on the handle and releases the front wheels over the obstacle.
  • a walking aid is known with a wheel arrangement formed in the area of the front wheels, each consisting of a large rear wheel and a small front wheel.
  • the front small wheel is arranged at a higher level in such a way that it directly can land on a step and roll over it if the rear large wheel encounters an obstacle in the form of a step edge.
  • the object of the invention is to provide a pushing device for use as an assistant or for transporting a load, which has a function for overcoming an obstacle that is easy to handle.
  • a sliding device comprises a frame, at least one front wheel connected to the frame, at least one rear wheel connected to the frame and at least one handle functionally connected to the frame for holding and gripping a user.
  • the framework has at least one longitudinal member which extends in the longitudinal direction between the rear wheel and the front wheel.
  • the longitudinal beam has a front beam and a rear beam, which are connected to one another in a relatively movable manner such that the front beam with the front running wheel connected to it can be raised as required by moving the front beam relative to the rear beam.
  • the solution according to the invention has the advantage that due to the design of the longitudinal beam with a front beam and a rear beam, which are connected to one another in a relatively movable manner, only a front part of a pushing device has to be raised in order to move a front running wheel or two or to raise several front wheels and bring them to the level of the obstacle in order to overcome an obstacle, such as a step. This reduces both the force and the moment to be applied by a user, resulting in easier operation, particularly for people with physical disabilities.
  • At least one support wheel is arranged on the frame.
  • a support wheel can either be designed as a permanently moving support wheel that has permanent contact with the ground and rolls with it even when using a walking aid without overcoming obstacles.
  • it can also be a support wheel that is arranged on the frame so that it can only be lowered as required and thus only has contact with the ground when it is required for a specific use of the sliding device or is associated with additional advantages.
  • One application for lowering a support wheel as required is overcoming an obstacle, such as a step.
  • a user with a sliding device according to the invention is directly in front of a step at whose level the front wheel or the front wheels of a sliding device must first be raised, it is advantageous if the at least one support wheel is first lowered to the ground and only then the at least one front wheel is lifted off the ground. This is raised to the level of the obstacle to be overcome.
  • a user of the sliding device according to the invention is also supported at the moment of lifting the front wheel or front wheels by the pushing device having contact with the ground at this moment through the at least one rear wheel and the at least one support wheel. Two such wheels are preferably provided in each case, so that the pushing device according to the invention has contact with the ground at the moment of lifting two front running wheels with two rear running wheels and two support wheels.
  • a functional unit with at least one functionally connected operating element is provided for raising the front carrier as required and/or for lowering the at least one support wheel as required.
  • Such an operating element is preferably arranged in the area of the at least one handle in such a way that it can be actuated by a user who is holding onto the handle while holding it.
  • the control element is preferably functionally connected to the functional unit in such a way that a function of the functional unit can be activated by actuating the control element in order to enable lifting of the front carrier with the front wheel connected to it by moving the front carrier relative to the rear carrier, as required or even to do it directly.
  • a functional unit of this type should therefore be understood to be both a blocking element that enables a relative movement between the front carrier and the rear carrier by releasing. Furthermore, such a functional unit should also be understood to mean drive elements that actively cause the front support to be raised as required, for example by actuating a drive motor.
  • a functional unit designed as a length adjustment unit which in practice can be realized by a large number of standard components.
  • a gas pressure spring or to pneumatic, hydraulic and/or electric drive units for example linear motors.
  • a change in length can be effected or permitted by simple actuation, for example by means of a Bowden cable that leads from a handle to the gas pressure spring, by allowing the gas pressure spring to be compressed.
  • the functional unit is preferably designed and arranged in such a way that it enables both the at least one support wheel to be lowered as required and the front support to be raised as required.
  • This is further preferably implemented in such a way that first the at least one support wheel is lowered until the support wheel is in contact with the ground and only then is it possible to raise the front support as required. In this way it can be ensured that while the front carrier with the front wheel connected to it is being raised, there is already contact between the at least one support wheel and the ground, and a user using the sliding device is thus protected from the sliding device tipping over with the help of the sliding device and is thus supported.
  • the functional unit is a connecting element between a vertical strut and the rear support or an element connected to the rear support.
  • the functional unit can be a connecting element between a support beam and a vertical strut, with the support beam being an element that is firmly connected to the rear beam.
  • the result is a structurally relatively simple sliding device that can be manufactured inexpensively.
  • a brake actuation element and/or the operating element for the functional unit is arranged in the area of the at least one handle in a sliding device according to the invention, a user of the sliding device can simultaneously hold on to the handle and actuate the brake operating element and/or the operating element for the functional unit.
  • the user can thus use a sliding device according to the invention as usual even while overcoming an obstacle and can also hold on to the handles when changing between different functional states of the sliding device.
  • Elements that can be operated while a user is holding onto a handle, in particular while he is enclosing the handle on one side with his thumb and on the other side with the other fingers, are particularly suitable as control elements.
  • a rotary handle which can be designed as a trigger or as a dosing element for the functional unit.
  • a push button or a lever can also be arranged in such a way that it can be operated with one finger without the user having to change the position of his hand on the handle significantly. In this case, I can continue to hold the user securely while using the control element.
  • a trigger In the function of a trigger, it may be necessary, for example, to turn the rotary handle by a certain angle in order to actuate a trigger element on a gas pressure spring and to use energy from the gas pressure spring to bring about a relative movement between the rear carrier and the front carrier or .raise and/or lower the front wheels.
  • a rotary handle can also be used - for example via a Bowden cable with two front supports and the front wheels attached to them - to rotate the front If necessary, pull up the carrier by turning the handle via the Bowden cable so that an obstacle, such as a step, is overcome with the front wheels by raising them to the level of the step.
  • the front carrier and the rear carrier are connected to one another via a rotary joint, a flexible element and/or a gear. Connections using a swivel joint are particularly easy to implement. These have the further advantage that the movement between the front support and the rear support is guided precisely, so that a user easily gets used to using a sliding device according to the invention.
  • the invention has been made in particular for such pushers in which the framework has two longitudinal beams, each longitudinal beam having a front beam and a rear beam and each front beam being connected to a handle by a vertical brace. This corresponds to the basic concept of pushing devices or walkers known from practice.
  • a support wheel is more preferably provided between a front wheel and a rear wheel, viewed in the longitudinal direction.
  • the support wheel of a sliding device according to the invention is raised by a height h s relative to the level of the running wheels, which is smaller than the radius of the rear running wheel, This makes it easier to overcome an obstacle, because the rear part of the pusher can be raised using the support wheel by simply pushing the pusher further forward.
  • the support wheel is then supported on the edge of an obstacle and pushes the rear beams with the rear wheels of a pushing device according to the invention upwards.
  • a drive element is provided, by means of which the at least one front running wheel can be raised independently of the muscular strength of a user.
  • a design is particularly advantageous when the sliding device is intended for users who only have very little muscle power or whose motor skills no longer function properly.
  • a locking element is provided in a sliding device according to the invention, which has to be released in order to lift the front carrier with the front wheel connected to it by relative movement in relation to the rear carrier, the locking element ensures that it can on the handles of a pusher cannot accidentally lift the front carrier with the wheels connected to it, for example because the user suddenly brakes the pusher by pulling the pusher backwards.
  • a gas pressure spring as already described above can serve as such a blocking element.
  • Depression engages and which must be solved to allow relative movement between the front support and the rear support.
  • blocking elements that can be released by applying a sufficiently large moment, for example locking balls that engage in complementary depressions.
  • Such blocking elements can also be provided in order to be able to raise the front carrier with the front running wheel connected to it by relative movement with respect to the rear carrier. Then only a sufficiently large moment has to be applied to cause the lifting of the front beam.
  • the sliding device 1 has a frame 7 which is constructed essentially symmetrically in relation to the central longitudinal axis.
  • the framework 7 has two longitudinal members 5, namely a left and a right longitudinal member, which each comprise a front member 2 and a rear member 10.
  • the rear supports 10 can also be referred to as rockers.
  • the side members 5 are connected to one another via at least one cross-connection element extending in the transverse direction of the vehicle (y-direction).
  • a scissor linkage 24 with two rods arranged in an X-shape and a joint arranged centrally at the point of intersection of the rods is provided as a cross-connection element.
  • This scissor linkage 24 makes it possible to bring the pushing device 1 into a compact transport or stowage configuration (not shown), in which the respective longitudinal beams 5 are brought into an immediately adjacent arrangement to one another.
  • one or more rigid cross-connection elements can also be provided in a simpler design variant if the sliding device 1 should not or does not have to be foldable.
  • a seat surface 30 is provided between vertical struts 6 which are each firmly connected to the longitudinal beams 5 .
  • the seat 30 is attached at seat height and serves as a temporary resting place for a user 40.
  • the seat 30 can be designed to be foldable and/or removable and is an optional feature.
  • the vertical struts 6 are designed to be adjustable in length—here telescopically.
  • a handle 21 for a person (user 40) using the sliding device 1 is provided at the upper end of the respective vertical strut 6 .
  • the height adjustability of the vertical struts 6 makes it possible to set the height of the handles 21 appropriately depending on the height of a user 40 .
  • Front wheels 3 are connected to the respective front carrier 2 .
  • the front running wheels 3 are each mounted such that they can rotate about a vertical axis 4 and can therefore be steered. Furthermore, the front running wheels 3 are mounted so as to be rotatable about a horizontal axis of rotation (not shown).
  • Rear wheels 12 are connected to the respective rear carrier 10 .
  • the rear running wheels 12 are mounted so as to be rotatable only about a horizontal axis of rotation (not shown) and are therefore not steerable.
  • Each rear support 10 is arranged to be relatively movable relative to the associated front support 2 .
  • this is realized in that a swivel joint 11 is provided as a connecting link, which makes it possible to pivot the respective front support 2 about the swivel joint 11 with respect to the rear support 10 .
  • the front supports 2 are pivoted parallel to the rear supports 10 .
  • parallel pivoting means joint and simultaneous pivoting. This is subsequently based on the Figures 6-12 shown and described in detail.
  • a support wheel 13 is connected to the respective rear supports 10 in each case.
  • the respective support wheel 13 is also rotatably mounted about a horizontal axis of rotation, not shown.
  • a support beam 14 is provided for the connection of the respective support wheel 13 .
  • the respective support beam 14 is fixed rigidly in relation to the associated rear beam 10 .
  • the support beam 14 can also be mounted such that it can pivot relative to the rear beam 10 about a horizontal axis of rotation (not shown).
  • the respective support wheel 13 is - viewed in the longitudinal direction of the pushing device 1 - arranged between the front wheel 2 and the rear wheel 12 .
  • the support wheels 13 are designed in the embodiment shown so that they have no contact with the ground when the vehicle is on a level surface.
  • a functional unit 20 is also provided.
  • the functional unit 20 is designed in particular in such a way that it enables the front wheel 2 to be raised as required by moving the front carrier 2 relative to the rear carrier 10 allows.
  • the functional unit comprises a length adjustment unit 25.
  • a gas pressure spring is provided as the length adjustment unit 25, which is extended and prestressed in the non-actuated state. In this state, the length of the length adjustment unit 25 is large, with the result that the support wheel 13 has no contact with the ground and the pushing aid can be operated in standard use.
  • the angle between the respective front side member 2 and the associated rear member 10 is essentially constant in this functional state, with the elasticity of the gas pressure spring developing a springing and damping effect and allowing a certain flexibility within limits. This leads to increased comfort for the user because bumps in the floor are either completely absorbed by the damping or are at least only partially transferred to the handles 21 .
  • the length adjustment unit 25 is connected to an operating element 22 designed as a push button in such a way that the gas pressure spring can be relieved by actuating the push button. If the push button is pressed, the gas pressure spring relaxes by shortening its effective length. As a result, the support wheels 13 pivot about a pivot point (not shown) on the rear support 10 and come into contact with the ground due to the force of gravity. Furthermore, the front longitudinal beams 2 with the front running wheels 3 can be pivoted upwards relative to the rear beams 10 by a user 40 pulling the handles 21 backwards against the direction of travel F and at the same time pressing them down in order to further increase the effective length of the gas pressure spring shorten.
  • the handles 21 serve as an interface to the user 40.
  • a control element 22 for the functional unit 20 and a brake actuation element 23 for the rear wheels 12 are arranged in the region of each handle 21.
  • the interconnection of the controls 22 and the brake actuators 23 is preferably selected so that a User 40 can simultaneously hold onto handles 21 with his hands and at the same time actuate the at least one operating element 22 for functional unit 20 and/or brake actuating element 23 .
  • Each of the operating elements 22 is preferably functionally connected to the functional unit 20 in such a way that when one operating element 22 is actuated on a handle 21, both length adjustment units 25 and thus both support wheels 13 can be operated (i.e. lowered) in parallel.
  • the sliding device 1 enables it to be used, in particular, to facilitate overcoming obstacles such as steps, with a particular advantage being that the sliding device 1 remains inherently stable during the entire process of overcoming obstacles.
  • the sliding device 1 is used commercially. It supports the user 40 and can be pushed manually.
  • this functional state also makes it possible to swivel the front part of the frame 7 backwards by shortening the effective length of the length adjustment unit 25, so that the pushing device 1 only has contact with the ground via the rear running wheels 12 and the support wheels 13 .
  • the pushing device 1 nevertheless remains inherently stable and can safely support the user 40 via the four wheels 12, 13 resting on the ground, despite the tilted position of the front longitudinal members 2 with the front wheels 3.
  • the operating element 22 and the functional unit 20 can also be designed in such a way that the length adjustment unit 25 can be continuously shortened depending on the actuation path of the operating element 22, for example by providing a lever, with the increasing actuation path of the lever effective length of the length adjustment unit 25 is shortened.
  • the support wheels 13 are first lowered to the ground in a first actuating path section, and then in a second actuating path section the front wheels 3 can be continuously raised as far from the ground as is necessary. The raising of the front running wheels 3 can thus be steplessly adjusted via the operating element 22 to the height of an obstacle to be overcome, in particular a step 50 .
  • the sliding device 1 by pressing and holding the operating element 22 in the 9 brought functional state shown and so far moved up to the obstacle until the front wheels 3 can roll on the level of the obstacle.
  • the front wheels 3 are set down at the level of the obstacle by releasing the control element 22, and at the same time the length adjustment unit 25 is extended again as far as possible, which happens in the illustrated embodiment by the rebound of the gas pressure spring.
  • the support wheels 13 are thus already partially raised again.
  • the support wheels 13 can thus be supported in lifting the rear support 10 further, in particular if the difference in height of the support wheel before it reaches the height of the obstacle, in particular a step 50, is less than the respective radius of the corresponding support wheel 13. Because then the user can Sliding device 1 simply push up or roll up to the height level of the obstacle or the stage 50 by further pushing on the support wheels 13, as can be seen from a synopsis of the Figures 10 and 11 is evident.
  • the height difference between the respective support wheel 13 in the extended state of the length adjustment unit 25 and the associated rear wheel 12 is preferably selected so that it is smaller than the radius of the rear wheels 12. Because then the above applies analogously to a further pushing of the pushing device 1 ie the sliding device 1 can be rolled up to the level of the obstacle by simply “pushing forward” (pushing) with the rear wheels 12 and thus be raised while rolling. This is from a synopsis of the Figures 11 and 12 apparent.
  • the user 40 pushes the pushing device 1 simply continues and is stably supported by the pusher 1 (cf. 11 and 12 ).
