Description

An automobile module for transport of handicapped persons, a handling assembly for this module, an automobile with the assembly, and a method of transferring the module
Technical field The technical solution relates to the field of wheelchairs, more particularly, it is an integrated drop-off module for automobiles for transport of handicapped persons, an assembly for transferring such a module into and from an automobile, an automobile with the assembly or the module, and a method for transferring the module into/from the automobile. Background of the invention
Persons who rely on wheelchairs for transport are limited in their use of passenger automobiles when using the usual method of transferring from the wheelchair to the automobile and from the automobile back to the wheelchair.
For a handicapped person in the role of a passenger or even a driver, the process of transferring from the wheelchair to the automobile seat is usually a demanding operation, and very often, these persons depend on the help of others. Only physically fit individuals in good condition can manage this demanding operation on their own, but then they either have to use a simple and lightweight folding wheelchair that they can store in the automobile themselves, or they have to leave the wheelchair outside the automobile. If the person being transported has to remain in the wheelchair during the transport by automobile, they either have to use a tipping or lifting ramp, or special single-purpose additional handling devices must be installed in the automobile. These devices are always quite complicated and therefore expensive and limit the person being transported as well as the user of the automobile and thereby limit the independence of the person with mobility impairment. A solution for transferring the wheelchair using a lifting ramp is described, for example, in the document FR2726182 A1. Another solution for transferring the wheelchair is known from the document W0200640886 A1. According to this document, in order to transfer the wheelchair, it is necessary to back the wheelchair onto a portion of the handling mechanism, the wheelchair is then lifted by an arm of the mechanism and transferred into the automobile, and finally, the wheelchair must be rotated so that it faces in the direction of travel. However, this mechanism is relatively design and space intensive and backing the wheelchair precisely onto the arm of the mechanism may not be easy or even possible for persons with reduced mobility.
Said solutions from the prior art do not provide sufficient freedom and independence in mobility for handicapped persons with reduced mobility when using an automobile that can be adapted relatively easily to their personal needs. Summary of the Invention
Said shortcomings are substantially eliminated by an integrated drop-off module for automobiles for transport of handicapped persons, wherein said module has a frame with running wheels, a seat, an electrical control and drive system with batteries arranged in the frame according to the invention, the essence of which lies in the fact that the module is provided with a lifting mechanism, an apparatus for adjusting the running wheels from a position for traveling outside the automobile to a position in the automobile and vice versa, means for fastening to seat hitches in the interior of the automobile, and, furthermore, hitches for fixing to a handling extension mechanism arranged in the inner portion of the body of the automobile. The hitches on the module, for fixing to the extension mechanism, may, for example, be also an opening in the module for sliding a portion of the extension mechanism. The module seat is preferably formed such that it corresponds to the corresponding automobile seat, in particular the driver or passenger seat. Therefore, after the module is transferred into the automobile, the module seat serves as an automobile seat.
The handling extension mechanism is preferably arranged on the floor of the automobile in the inner portion of the body.
In order to lift and support the lifted module and set it in the correct starting position, the lifting mechanism has mechanically extendable supports, which are preferably formed as telescopic.
For recharging the module batteries, it is particularly suitable for the module electrical system to be connectable to the automobile’s electrical network.
An advantage of the proposed technical solution is the possibility of using a modified automobile seat or replacing it with a similar type of comparable characteristics and equipping it so that it can be used as an independent electrical mobile wheelchair when released from the vehicle. Handling of the seat from the exterior to the interior of the automobile and vice versa is carried out by means of a floor extension system arranged at the place of the seat in the automobile, usually at the place of the driver or passenger.
The seat is placed on a frame equipped with electronics and during the automobile ride the batteries can be recharged from the car batteries, the automobile’s alternator, or by recuperating the automobile’s kinetic energy.
The module running wheels are laid on the module frame and are adjustable between two positions. Their first position for positioning in the automobile is determined by the ground clearance of the passenger automobile. In the second position, the running wheels are extended for travel of the module outside the automobile.
Telescopic or other extension mechanisms are attached to the module frame. Outside the automobile, they lift the module to the required height above the automobile floor level. The control of these mechanisms will allow for a stable stationary position of the module and height arresting thereof regardless of surface irregularities.
To transfer the module into the interior of the automobile or out of the interior of the automobile, there is an extension mechanism built into the floor of the automobile. The extension mechanism does not limit space or automobile use. It is designed such that instead of the module or another object, a normal seat of this automobile may be mounted in the automobile.
When the module is loaded into the automobile, once the extension mechanism has reached the final position, the module is anchored to the automobile’s safety features for hitching the seats and usually simultaneously connected to the automobile’s electrical network.
This system will significantly increase the independence of the wheelchair user, including persons with reduced mobility.
The system of lifting the module and further handling it, including a person can be used for industrial use in the transport of shipments, etc.
The shortcomings of the solutions known from the prior art are furthermore solved to a certain extent by a handling assembly for automobiles adapted to handling the module for transport of handicapped persons. This module, e.g., the module of the invention described above, comprises a frame with running wheels, a seat, and an apparatus for adjusting the running wheels towards and away from the seat. The handling assembly comprises a handling extension mechanism designed to be placed in the automobile and adapted to be hitched to the module, wherein the extension mechanism is adapted to transfer the module between the space inside the automobile and the space outside the automobile in at least horizontal direction.
By using the apparatus for adjusting the running wheels, the module can be transferred into the automobile without the need to significantly lift the module, as said apparatus ensures that the wheels are adjusted such that they do not impede the transfer of the module into the automobile. In the case of some types of automobiles where the floor is more distant from the road, it may be appropriate to lift the entire module slightly, but this slight lifting may be done at smaller intervals, e.g., up to 10 cm, such that it may be implemented with a more compact and cheaper lifting mechanism than in the prior art where the entire module has to be lifted by, for example, 30 cm, for example by driving the module up the ramp. The assembly of the invention thus allows the module, e.g., a wheelchair, to be transferred to the place of the seat in the automobile without the need for assistance of other persons, thereby facilitating the transport of persons with reduced mobility. In addition, a lower automobile ceiling height is sufficient to place the module in the automobile than is necessary to place the module without the apparatus for adjusting the running wheels.
The extension mechanism is preferably adapted to be attached to the floor of the automobile and to be adjusted to at least a folded position and an unfolded position, wherein in the unfolded position, a portion of the extension mechanism extends out of the automobile and in the folded position, the extension mechanism is located entirely inside the automobile, wherein in the folded position when viewed from above, the longitudinal axis of the automobile passes outside the handling assembly. Therefore, in the unfolded position, the extension mechanism extends outside the automobile such that the module may be hitched by it and then, by adjusting to the folded position, the module is transferred into the automobile. The passage of the longitudinal axis of the automobile outside the assembly, in other words, the fact that the assembly is located on one lateral half of the automobile and does not extend to the other lateral half makes it possible, if necessary, to place two assemblies of the invention side by side in the automobile.
Preferably, the extension mechanism comprises at least two mutually shifting members, wherein the first member is adapted to be fastened in the automobile and the second member is adapted to be removably hitched to the module. The extension mechanism is thus preferably a telescopic mechanism, which makes it possible to provide a sufficient extension length, for example up to 1 m, preferably up to 1 ,2 m, while keeping the mechanism sufficiently compact such that it can be integrated into the automobile without preventing the transport of other persons or objects. Preferably, the extension mechanism comprises at least three members. The extension mechanism preferably comprises a drive for mutual movement of the members, i.e., for adjusting the mechanism between its positions. The drive may be common for the movement of all members or more members, or all members may have their own drive designed to move only one member.
Removable hitching of the module may be performed by, for example, sliding a portion of the extension mechanism into a suitably shaped opening in the module, preferably in combination with subsequent securing of this portion against spontaneous falling out by a safety lock. It is also possible to hitch the module, for example, by slipping a suitably shaped hitch under the seat or chassis of the module. Preferably, the module is hitched on its lateral side, it is also possible to hitch the module from the back or front or to hitch it from multiple sides. Furthermore, the module is during hitching operation preferably oriented in the direction of travel of the automobile such that it is not necessary to rotate the module towards the windscreen during transfer. As a result, the assembly of the invention does not need to comprise a mechanism for rotating the module, which would increase its space requirements as well as its structural complexity and cost.
Preferably, the extension mechanism further comprises a driving element selected from a group comprising chains, belts, cables, and toothed belts, and further comprises a drive for moving the driving element, wherein the driving element is hitched to at least one member. Preferably, it is hitched to at least two different members to ensure their mutual shifting. Preferably, it is hitched to at least one of the members non-movably. The movement of this driving element therefore ensures the mutual shift of the members and thus the transfer of the extension mechanism from the unfolded position to the folded position and vice versa. It is also possible to use other types of mechanisms for linear shift, such as toothed combs or pistons.
Preferably, the extension mechanism further comprises a plurality of freely rotatable elements selected from a group comprising rollers, wheels, gears, and pulleys, wherein the rotatable elements are placed on at least one of the members and define the position and movement of the driving element. Therefore, the driving element passes between these rotatable elements and the rotatable elements are placed on the individual members or other portions of the extension mechanism and assembly such that the movement of the driving element results in folding/unfolding of the extension mechanism. The extension mechanism may comprise a plurality of driving elements, for example one for folding and one for unfolding. Each driving element can have its own drive, for example one drive can be placed on the assembly non-movably relative to the automobile floor and another drive non-movably relative to the hitched module.
Preferably, one driving element is adapted to move at least one member in two opposite directions. Thus, a single driving element can ensure the folding and unfolding of the extension mechanism. For example, the driving element may be fixedly connected at both ends to one of the members, to the drive placed approximately midway along the driving element (particularly at the point of extension of the extension mechanism to midway along the total extension), e.g., anywhere in the middle third of the length or anywhere in the middle three fifths of the length, etc., wherein the place of the drive divides the driving element into two portions the relative length of which varies with the movement of the drive. The arrangement of the rotatable elements is such that the movement by the drive to one side, which thus lengthens one portion and shortens the other portion of the driving element, causes the extension mechanism to fold and the movement by the drive to the other side shortens the first portion and lengthens the second portion, thereby unfolding the extension mechanism. It is also possible to connect the two ends of the driving element such that a fixed connection to a portion of the extension mechanism can be the at a single place of the driving element.
The handling assembly of the invention preferably further comprises a lifting mechanism adapted to vertically shift the module hitched to the extension mechanism. The lifting mechanism therefore allows the distance between the ground and the running wheels to be further increased before transferring the module, thus allowing the module to be transferred even into automobiles with a higher ground clearance. For example, the lifting mechanism may be implemented as a linear drive placed between the place for hitching the extension mechanism to the module and the end of the extension mechanism.
Preferably the adaptation for hitching the extension mechanism to the module is performed in a removable manner by means of a projection on the extension mechanism adapted to be slid into a complementary opening on the lateral side of the frame of the module. A hitch realized this way may be further provided with a safety lock for securing the projection in the opening.
The shortcomings of the solutions known from the prior art are further eliminated to a certain extent by an automobile which comprises the handling assembly of the invention described above. Furthermore, the automobile comprises a module for transport of handicapped persons, wherein the module comprises the frame with the running wheels, the seat, and the apparatus for adjusting the running wheels towards and away from the seat. The handling assembly is adapted to transfer the module into and from the automobile, and the handling assembly with the apparatus for adjusting the running wheels are adapted to slightly lift the running wheels relative to the ground. The automobile therefore comprises an integrated module for transport of handicapped persons and allows the transfer of this module into and from the automobile.
Preferably, the slight lifting of the running wheels relative to the ground is a slight lifting of at least 15 cm. More preferably of at least 20 cm. This distance can ensure that the lower end of the running wheels is above the automobile floor level when the module is being transferred such that the running wheels do not interfere with the transfer.
Furthermore, the shortcomings of the prior art are to a certain extent eliminated by a method of transferring the module for transport of handicapped persons, comprising the frame with the running wheels, the seat, and the apparatus for adjusting the running wheels towards and away from the seat, into and from the automobile. Such an automobile comprises the handling assembly of the invention, for example it is the automobile of the invention described above, and the method comprises the following steps: · arrival of the module next to the opening defining the door of the automobile; the exact position where the module stops may be determined by an additional positioning system that ensures the module is driven to the exact place and/or the user is guided to drive the module to the exact place for subsequent hitching of the module.
• extension of a portion of the extension mechanism from the automobile through the given opening; the size or length of the portion of the extension mechanism extending out of the automobile depends mainly on the structure of the extension mechanism and affects how far from the side of the automobile it is appropriate to stop the module before transferring it into the automobile.
• hitching the module by the extension mechanism; this step may involve an additional step of securing the hitching, for example by pressing a button to operate an electronic safety lock, a lever to operate a mechanical safety lock, etc.
• slightly lifting the running wheels by means of the apparatus for adjusting the running wheels; this step may be further associated with slightly lifting the module by the lifting mechanism. Both of these steps can occur one after the other or simultaneously. · Retracting the extension mechanism with the module hitched into the automobile. Preferably, for the module, in the state with the running wheels closest to the seat, the perpendicular projection of the module in a vertical plane parallel to the longitudinal axis of the automobile does not extend in any place past the perpendicular projection of the door opening in the same plane. Thus, no portion of the module prevents retraction. A part of the assembly may be safety features or sensors preventing possible injury to the user during the transfer, e.g., caused by the frame of the door.
The method of transferring the module preferably further comprises a step of
• fastening the module in the automobile. This step may be implemented, for example, by means of pins on the floor, portion of the extension mechanism, etc., and complementary openings in the bottom portion of the module frame. Preferably, this step is partly performed by the lifting mechanism by which the module is laid on the floor or a suitable portion of the assembly and mounted on said pins. This mechanism can also be provided with a safety lock. Preferably, the handling assembly and the module are adapted to implement the method during use of the module by a user seated on the seat. In particular, it is suitable to provide the extension mechanism as sufficiently firm to prevent damage or excessive bending during the transfer of the module.

Exemplary embodiments of the invention
The invention will be further described by means of exemplary embodiments with reference to the respective drawings. An integrated drop-off module 2 for automobiles 1 for transport of handicapped persons has a frame on which running wheels 4 are positioned. Furthermore, a seat 5 corresponding to the seat of the automobile 1 is connected to the frame. An electrical control and drive system of the module 2, together with batteries, are arranged in the frame. The module 2 is further provided with a lifting mechanism 6, an apparatus 7 for adjusting the running wheels 4 from a position for traveling outside the automobile 1 to a position in the interior of the automobile 1 and vice versa. The module 2 is also provided with means for fastening to seat hitches in the interior of the automobile 1, and furthermore, it is provided with hitches for fixing to a handling extension mechanism 3 arranged in the floor of the automobile 1_.
In the described example, the lifting mechanism 6 has telescopically extendable supports and it is part of the module 2, but in alternative embodiments, the lifting mechanism 6 may also be part of the extension mechanism 3 or other component performing the transfer of the module 2. The electrical system of the module 2 is connectable to the electrical network of the automobile 1 to allow the batteries to be recharged from the electrical network of the automobile 1 while traveling. The user of the module 2 arrives at the automobile 1 in the direction of travel, wherein the module 2 is in wheelchair function (Fig. 1). Using sensors, the module 2 is oriented to the exact position for loading. The telescopically extendable supports of the lifting mechanism 6 lift the module 2 to the required height (Figs. 2 and 3). The supports lift independently and allow the module 2 to be aligned in a horizontal position against the extension mechanism 3, which extends laterally from the automobile 1 under the module 2. Then the telescopically extendable supports are retracted and the module 2 resting on the extension mechanism 3 is ready to be transported inside the automobile 1 (Fig. 4). This is done by means of a reverse movement of the extension mechanism 3. When the end position is reached, the module 2 is securely hitched by the anchoring system and thus functions as a standard seat of the automobile 1 (Figs. 5 and 6). The procedure of transferring the module 2 in the prior art was carried out without a handicapped person in the seat 5 of the module 2. According to the present invention, this transfer of the module 2 can also be performed with a handicapped person. This means that the person does not depend on the help of another person during the transfer of the module 2.
When the module 2 is placed in the interior of the automobile 1 and mechanically attached and secured in place, the respective energy and communication lines between the module 2 and the automobile 1 are interconnected, including data channel connectivity for recharging electric batteries of the module 2 and sharing the necessary data.
For example, the extendable supports may be implemented as threaded rods, wherein the vertical shift of the frame of the module 2 is ensured by rotation of these rods. Each support can then include an electric motor for rotating the rod. It is also possible to use drives with pneumatic or hydraulic pistons, where at least one piston, preferably individually controllable, is placed in each support. During extension, the lower end of the support approaches the ground and when the support contacts the ground, further extension of the support causes the lifting of the module 2.
The apparatus 7 for adjusting the running wheels can be implemented, for example, as a scissor mechanism, where the front running wheels 4 are fastened on one arm, the rear ones on the other arm, wherein these arms intersect each other and are pivotably connected at the place of intersection. The pivot of the arms in this connection then causes the shortening or lengthening of the vertical distance between the running wheels 4 and the seat 5 or the frame of the module 2. A part of the solution are appropriate elements to limit potential risks arising from incomplete interconnection of the individual parts or their incorrect functioning to prevent potential risks to users of the device.
When transferring the module 2 to the place of the driver of the automobile 1, after it has been fixed, the seat 5 may be transferred to the correct position for driving the automobile 1. The procedure for transferring the module 2 to the place of the passenger is basically the same. This applies also for eventual transfer to the places of the rear seats of the automobile 1.
The extension of the module 2 outside the automobile 1 follows the same process, but in reverse order.
Furthermore, the object of the invention is a handling assembly for automobiles 1 used for handling the module 2 for transport of handicapped persons. Such a module 2 may therefore be particularly a wheelchair or similar means of transport of persons with reduced mobility. The module 2 comprises a frame which is the basic structural element of the module 2, running wheels 4 for moving the module 2, a seat 5 for seating the user, and an apparatus 7 for adjusting the running wheels 4 towards and away from the seat 5 (cf. Figs. 8 and 11 ). In the normal position of the module 2, the movement of the running wheels 4 towards the seat 5 is a movement with an upward component, however, depending on the structure of the module 2, in particular its apparatus 7 for adjusting the running wheels 4, the movement towards the seat 5 may also have a horizontal component. For example, when using the scissor mechanism as the apparatus 7 for adjusting the running wheels 4, due to this mechanism, the running wheels 4 move up or down relative to the seat 5, or the seat 5 moves down and up relative to the running wheels 4, but at the same time the front running wheels 4 move away from or toward the rear ones.
The handling assembly of the invention comprises an extension mechanism 3, which is used for fastening in the automobile 1 and hitching to the module 2. The extension mechanism 3 is shown e.g., in Figs. 8 and 10 in the unfolded position and in Figs. 19 and 20 in the unfolded, or folded, position, respectively. This hitching to the module 2 is preferably implemented in a removable manner (cf. Figs. 15 and 16), but alternative embodiments with a fixed hitching are also possible, where the module 2 is fixedly and possibly permanently hitched to the automobile 1 by means of the handling assembly. The extension mechanism 3, when hitched to the module 2, is used to transfer the module 2 between the space inside the automobile 1, e.g., the place for the driver’s seat, and the external space, in particular the space next to the door of the automobile 1. This transfer can then take place only in the horizontal direction, in particular perpendicular to the longitudinal axis of the automobile 1 and can also take place in both the horizontal and vertical directions, where, for example, the module 2 is slightly lifted before or during the horizontal transfer into the automobile 1, as indicated in Fig. 12, where the module 2 is slightly lifted before the horizontal transfer begins.
In an exemplary embodiment shown in Figs. 7 to 20, the extension mechanism 3 is implemented as a telescopic mechanism with four members which are mutually shiftably hitched and their shifting is implemented by a chain mechanism. The first member is composed of a pair of metal profiles 8 fixedly connected to the floor of the automobile 1 through a supporting structure 10. The second member is composed of another pair of metal profiles 8, each of which is shiftably connected to one of the profiles 8 of the first member. The third member is implemented analogously to the second member as a pair of profiles 8 shiftably connected to the profiles 8 of the second member, and the fourth member is composed of a metal plate shiftably connected at two opposite sides thereof to both profiles 8 of the third member.
In the preferred embodiment shown, the members are composed of C-profiles, wherein their mutual movement is implemented for each pair of adjacent profiles 8 by a pair of wheels 1_2 fixedly connected, while maintaining their free rotation. The wheels 1_2 are shiftably, or slidably, hitched in one profile 8 and are rotatably connected to an attachment plate 13 located outside the profile 8, as can be seen in Fig. 18. By attaching this plate to the next profile 8 of the following member, a shifting, telescopic connection of the members is realized. As can be seen from the drawings, the members taper gradually from the first member such that in the folded state, each member except the first one is placed between the profiles 8 of the previous members. The attachment plate 13 may be metal or plastic, preferably at least on the surface made of a sliding plastic. The size of the wheels 12 used is preferably chosen such that the contact area of the wheels 12 with the inside of the profile 8 is as large as possible, and therefore such that the stress on the profile 8 by pushing is as small as possible. The material of the wheels 12 is preferably chosen such that the use of the assembly wears down the wheels 12 and any clearance defining elements between the sides of the wheels 12 and the profile 8 (i.e., in the axial direction of the wheels 12) rather than the profile 8. In an exemplary embodiment, wheels 12 made of brass are used and the inner lateral sides of the profiles 8 are provided with inserts made of a sliding plastic (e.g., PA6, POM-C or Iglidur). After the wheels 12 are placed in the profiles 8, the profiles 8 are preferably provided with stops for securing the wheels 12 inside the profile 8.
The first member is attachable to the floor of the automobile 1 by means of the supporting structure 10 shown in Fig. 17. This structure may be welded, riveted, bolted, or otherwise fixedly connected, both together and to the automobile 1 or to the extension mechanism 3. The supporting structure 10 in the shown embodiment comprises steel profiles on the front and rear sides (where the front side is the side closer to the windscreen after mounting to the automobile 1) connected by steel bands.
All four members define path for movement of the driving element - in this embodiment of the chain 15. The chain 15 forms a loop passing between gears 16 placed on the members, wherein, with the exception of one of the gears 16 on the fourth member, which is located closest to the module 2 when the module 2 is hitched before beginning to transfer the module 2 into the automobile 1 and fixedly connects the chain 15 to the fourth member, all the gears 16 are freely rotatable about the vertical axes of rotation. Each of the profiles 8 forming the first three members comprises two gears 16, wherein on one side, in the direction of the longitudinal axis of the automobile 1, from the fourth member, the distance of the gears 15 on the particular profile 8 is greater on the corresponding profile 8 on the other side from the fourth member. Furthermore, a part of the extension mechanism 3 is a motor driving a gear wheel locked in the chain 15, wherein the place where it is locked divides the chain 15 into an extending portion and a retracting portion. A part of the mechanism may be one or more tensioners of the chain 15. The fixed hitching of the chain 1_5 to the fourth member can be implemented by an arrested toothed wheel 16 as shown in the drawings, but it is also possible to use another fixed connection.
The extending portion is tensioned when the extension mechanism 3 is extended from the automobile 1 - in the embodiment shown in Figs. 21 and 22, when the chain 15 is moved counterclockwise. As a result of this tensioning caused by the rotation of the motor-driven gear, the extending portion is shortened, which, due to the distribution of the gears 16 in contact with this portion, results in the movement of the members from the automobile 1 to the unfolded position of the extension mechanism 3, i.e., the lengthening and extension of the extension mechanism 3. The retracting portion lengthens during the extension process, as can be seen from comparing Figures 21 and 22, which is due to the placing of the gears 16 in contact with the retracting portion closer together on the members of the telescopic extension mechanism 3.
When the extension mechanism 3 is retracted, the motor tensions the retracting portion of the chain 15, which thereby shortens and pulls the members closer together to the folded position of the extension mechanism 3. In the embodiment shown, the motor is placed such that its gear is locked in the chain 15 at the place where the chain 15 is located regardless of the state, or position, of the extension mechanism 3. So, for example, at the place where the chain 15 is hitched by the gears 16 attached to the first member.
The members are preferably implemented such that the chain 15 is surrounded by the covering elements 14 such that injury to persons by the moving chain 1_5 or the chain 15 catching on another portion of the assembly is prevented. For example, each member may be provided with additional profiles or covers defining between them a space for the passage of the chain 15 and the place of the gears 16 and for preventing access to the chain 15 and the gears 16. In some embodiments, the space for the passage of the chain 15 may be defined directly by the profiles 8 forming the members of the extension mechanism 3. The covering elements 14 in the embodiment shown are placed on the profiles 8 forming the members, see Figs. 19 and 20. Their material is chosen such that they are firm and sliding, i.e., in the event of contact between the chain 15 and the covering elements 14, the chain 15 is prevented from catching on.
In alternative embodiments, the chain mechanism may be arranged differently than shown in the drawings, for example, the gears 16 defining the path of movement of the chain 15 may be oriented with the axes of rotation horizontal, wherein in such an embodiment, the members are spaced apart from each other in a vertical direction. Flowever, embodiments in which the chain moves in a horizontal plane, such as those shown in the drawings, are normally more preferred in terms of the height of the extension mechanism 3.
As can be seen from Figs. 7 to 14, in the folded state, the extension mechanism 3 has its entire volume on one side relative to the longitudinal axis of the vehicle, i.e., when viewed from above, the longitudinal axis does not pass through the extension mechanism 3. This makes it possible to place two handling assemblies in one automobile 1, e.g., instead of the two front seats. It can be seen from Fig. 14 that in the folded position of the extension mechanism 3, the whole assembly does not extend past the module 2 by more than one third of its width or length when viewed from above. This compactness of the assembly allows it to be placed in standard automobiles 1, wherein such an automobile 1 can still carry additional passengers and can carry cargo in the luggage compartment.
In the embodiment shown, a part of the fourth member is a hitch V\_ for the module 2. This hitch 1J_ is implemented as a projection adapted to be slid into a complementary opening in the frame of the module 2 (see in particular Figs. 15 and 16). To be able to implement this sliding when the extension mechanism 3 is unfolding, a part of the module 2 and/or the handling assembly or the automobile 1 may be a positioning system that enables the user of the module 2 to be informed of the correct position for stopping the module 2 before the module 2 begins to be transferred into the automobile 1. Such a positioning system may include an infrared source and sensors, lasers, and light detectors, distance sensors, a camera, a projector, etc. The length of the hitch 1J_ may vary in various embodiments, for example, depending on its cross-section, the weight of the module 2 and the expected weight of the user, the shape and material of the hitch 1J_ used, etc. The opening in the module 2, preferably in its frame, has a complementary shape to the hitch 1_1_, preferably such that sliding of the hitch V\_ into the opening and possible securing by a safety lock against unwanted drop-out of the hitch V\_ is sufficient to secure the module 2 on the extension mechanism 3. Flowever, in some embodiments, the hitch Y\_ may be secured in the opening by, for example, a pin passing through the opening with the hitch 11 where the pin is manually slid through the frame of the module 2, by a screw connection, etc. The safety lock may be mechanically or electronically controlled, for example, it may be implemented as a movable projection in the opening in the frame of the module 2 engaging a recess on the hitch 1J_ and controlled by an operating rod or electromagnet.
To retract the module 2 into the automobile 1, it is advisable to slightly lift the running wheels 4 above the floor level of the automobile 1. This slight lifting is implemented by the apparatus 7 for adjusting the running wheels 4, as described above, but in order to provide sufficient slight lifting for different types of automobiles 1, it is advantageous if the handling assembly further comprises a lifting mechanism 6. In the embodiment shown in Figs. 7 to 16, the lifting mechanism 6 is carried by the fourth member and the hitch V\_ for hitching the module 2 is carried by this lifting mechanism 6. After the hitch V\_ has been slid into the complementary opening in the frame of the module 2, it is thus possible not only to slightly lift the running wheels 4 but also to slightly lift the entire module 2 on the lifting mechanism 6 (cf. Figs. 11 and 12). Preferably, this achieves a slight lifting of the running wheels 4 relative to the road/pavement by at least 20 cm, more preferably at least 25 cm. For example, the apparatus 7 for adjusting the running wheels 4 may provide for a lifting by 15 to 20 cm, and the lifting mechanism 6 may provide for a lifting by a further 5 to 10 cm. The lifting mechanism 6 may include, for example, a linear drive adapted to move the hitch 1J_ relative to the fourth member, where the linear drive may be e.g., hydraulic, pneumatic, or may be a drive with a toothed comb and a driven gear and the like.
Flowever, alternative embodiments of the assembly without the lifting mechanism 6 are also possible. In further alternative embodiments, the lifting mechanism 6 may be placed between the first member and the floor of the automobile 1 such that the entire extension mechanism 3 is slightly lifted. This mechanism is shown in Figs. 25 to 28. Embodiments combining the lifting mechanism 6 between the floor or supporting structure 10 and the first member and the lifting mechanism 6 between the fourth member and the module 2, or another member and the module 2 in embodiments with a different number of members than four, are also possible. In other embodiments, the lifting mechanism 6 is placed between some two members. In further embodiments, the apparatus 7 for adjusting the running wheels 4 may be implemented by any mechanism other than the above scissor mechanism. In some embodiments of the assembly, the lifting mechanism 6 may be implemented by means of telescopic struts by which the module 2 is slightly lifted against the road/pavement before the module 2 is hitched by the hitch 11 i.e., it is also possible to use the lifting mechanism 6, which is a part of the module 2.
In alternative embodiments, the above-described chain drive for the extension mechanism 3 may be replaced by, for example, a similar drive where, however, a cable, toothed comb, or even a belt without teeth, etc., is used as the driving element. In the case of replacing the chain 15 by another driving element, it may be necessary or preferable to replace the gears 16 by belt pulleys, pulleys, etc. It is also possible to use a different kind of mechanism, for example, to use an extension using toothed combs and motor driven gears for each comb or to use linear drives for each member -e.g., hydraulic or pneumatic pistons. The telescopic extension mechanism 3 may comprise any number of members, e.g., only two or even more than four of the embodiment shown. The shifting connection of the members can be implemented for example by sliding bearings, wheels, rails, etc. In some other embodiments, the connection of the extension mechanism 3 to the module 2 may be implemented in another manner than by the described hitch V\_ engaging the complementary opening in the module 2. For example, it is possible to use a screw connection or suitable quick-release elements to easily secure the module 2 to the extension mechanism 3 and to release it, preferably without the use of additional tools.
Another object of the invention is the automobile 1 comprising the above-described handling assembly for transferring the module 2 for transport of handicapped persons and/or the automobile 1 comprising the integrated drop-off module 2 described above with reference to Figs. 1 to 6 or another module 2 adapted to be handled by the assembly of the invention. This automobile 1 may comprise an assembly according to any of the above embodiments, i.e., the assembly described with reference to the drawings, or any modification or alternative thereof. The automobile 1 may be implemented such that the seat 5 of the module 2 is the driver’s seat when transferred into the automobile 1. However, alternatively it can be a passenger seat or a rear seat. In some exemplary embodiments, the automobile 1 comprises two or more assemblies of the invention, in particular instead of both front seats. To enable two assemblies to be placed side by side, it is preferable if neither assembly of the invention extends past the longitudinal axis of the automobile 1 in any of its positions.
The handling assembly of the invention is, together with the apparatus 7 for adjusting the running wheels 4 of the module 2, preferably adapted to slightly lift the running wheels 4 before transferring the module 2 into the automobile 1, above the floor level of the automobile 1. Preferably, this slight lifting is at least 15 cm, more preferably at least 20 cm, and even more preferably at least 25 cm. In order to achieve a higher slight lifting, e.g., more than 20 or 25 cm, it may be appropriate to combine the slight lifting by means of the apparatus 7 for adjusting the running wheels 4 with the slight lifting by means of the lifting mechanism 6; however, in some embodiments, the entire slight lifting may be performed by the apparatus 7 for adjusting the running wheels 4.
Furthermore, the object of the invention is a method of transferring the module 2 for transport of handicapped persons to/from the automobile 1_. This module 2 may be any module 2 of the various embodiments described above, and it may also be any other module 2 adapted to be transferred by the assembly of the invention. This method may be implemented on the integrated drop-off module 2 of the invention and may be implemented by the assembly and/or automobile 1 of the invention, wherein it comprises the following steps:
• Arrival of the module 2 next to the opening defining the door of the automobile 1. The exact place where the module 2 needs to arrive can be determined using the positioning system described above. In some embodiments, it may be determined only by the user’s visual assessment of the position of the module 2 relative to the extension mechanism 3 of the assembly. The door preferably opens before this step, but in some embodiments, it may open after this step. The automobile 1 of the invention may comprise a system for automatically opening the door.
• Extension of a portion of the extension mechanism 3 from the automobile 1 through the given opening. The size of the extension is 884 mm in the embodiments shown, preferably in the range of 400-1200 mm, more preferably 600-1200 mm, but in general, it can be arbitrary. For example, only a portion of a member of the extension mechanism 3 may extend from the automobile 1 in this step, but also several whole members.
• Hitching the module 2 by the extension mechanism 3. Preferably, this step will take place automatically after the module 2 has been stopped in the correct position and the mechanism has been extended, and possibly after the user has given the instruction. The hitching of the module 2 may be secured by the safety lock as described above; in such an embodiment, manual securing of the safety lock by the user or pressing a button for electronic securing may be required.
• Slightly lifting the running wheels 4 by means of the apparatus 7 for adjusting the running wheels 4. In some embodiments, a part of the method is a step of slightly lifting the module 2 by the lifting mechanism 6. This step can also be implemented automatically or in response to an instruction from the user of module 2.
• Retracting the extension mechanism 3 with the module 2 hitched into the automobile I. The user may preferably be seated in the seat 5 of the module 2 during this step, as well as the previous steps. Therefore, it is preferable if the handling assembly, in particular the extension mechanism 3 and the lifting mechanism 6 with the hitch 1J_, is dimensioned to withstand the load during the transfer of the module 2 not only due to the weight of the module 2 but also due to the weight of the user.
• Fastening the module 2 in the automobile 1. This step may be implemented, for example, by means of mechanical safety locks adapted to secure the position of the module 2 relative to the floor of the automobile 1_. For example, the first member of the extension mechanism 3 or the supporting structure 10 may comprise several pins 9 and the frame of the module 2 may comprise several openings for the entry of the pins 9, wherein after the module 2 is retracted into the automobile 1, the module 2 is seated by moving downwards on the lifting mechanism 6, the pins 9 engage the openings and can then be further secured in each opening by a safety lock engaging a cut-out in the pin 9. This securing is shown in Figs. 23 and 24.
In some embodiments, the lifting mechanism 6 may be adapted not only to slightly lift the module 2 relative to the position in which the module 2 is hitched by the extension mechanism 3 but also to transfer the module 2 downwards. Such a lifting mechanism 6 may be suitable, for example, for fastening the module 2 in the automobile 1_. The transfer of the module 2 out of the automobile is done in an analogous manner, where the corresponding steps are performed in reverse order. Therefore, the module 2 is unlocked, extended from the automobile 1 by unfolding the extension mechanism 3, the lifting mechanism 6 with the module 2 is lowered, the running wheels 4 are lowered to road level, and the extension mechanism 3 is detached from the module 2.
The alternatives and modifications described above for any embodiment may also be applied to any other embodiment as long as the nature of the embodiments does not directly preclude this. Thus, for example, various extension mechanisms 3 may be combined with various lifting mechanisms 6, various hitches V\_ and methods of securing the hitch 1_1_, with variously implemented modules 2, etc. In particular, the corresponding features of the module 2, assembly, or automobile 1 of the invention can be applied with any necessary modifications to the method of the invention and vice versa, just as the alternatives described above for the assembly of the invention can be applied to the automobile 1 or module 2 of the invention, etc. Industrial applicability
The module 2, the automobile 1, the assembly, and the method of the invention can be used for transport of a handicapped person outside the automobile 1 and as a driver or passenger seat in the automobile 1 without the need for a transfer. They can be used for automobiles 1 with various drives, including hybrid and electric ones. They can also be used for handling and transporting shipments and other items.
