This generates the space required for rotating functional element.

Description

Technical Field

[0001] This invention belongs to the field of mechanical engineering and mechanics, and is particularly advantageous for use in the equipment of passenger transport vehicles (e.g., motor vehicles), but can also be used in, for example, the cabins of aircraft. Background Technology

[0002] Inside passenger compartments or passenger vehicles, there is typically limited available space, which should be utilized as much as possible. Some applications are known where functional elements provide multiple functions and, for this purpose, expose one of their various surface areas to or towards the occupants of the passenger vehicle to provide a specific function. These functional elements can also be rotated to display different surface areas to occupants, for example, surface areas with different functions.

[0003] For example, patent document DE10258018A1 discloses a handrail device that can rotate about its longitudinal axis within a support, thereby providing a passenger with one of two opposing surface areas of the handrail positioned above. Thus, the user can select different usage options by rotating the handrail.

[0004] One problem with the known device is that, due to the relatively wide armrests, a large amount of space is required for rotation under the armrests. Utility Model Content

[0005] In view of the background of the prior art, the purpose of this utility model is to create a functional device that can rotate with the least possible space requirement.

[0006] This objective is achieved by means of a functional device for use inside a passenger transport vehicle. The dependent claims propose possible embodiments of the functional device.

[0007] Therefore, the present invention relates to a functional device (e.g., a handrail device) for use inside a passenger transport vehicle, wherein the functional element has at least two separate surface areas and is mounted on a support so as to be able to rotate or pivot about a rotation axis, such that a first or second surface area of ​​these surface areas optionally faces the interior and a corresponding other area faces away from the interior, wherein the rotation axis or at least a portion thereof is movable into the interior.

[0008] Moving a portion of the rotating shaft can be understood as meaning that a section of the rotating shaft pivots, while a point, specifically the bearing point around which the rotating shaft can pivot, remains stationary. This point may be located in a pivot bearing through which the rotating shaft passes, and in which the functional element is mounted, allowing it to rotate about the rotating shaft on one side. Because the rotating shaft is movable, particularly capable of displacement or pivoting at one end into the interior of a passenger transport vehicle (e.g., a motor vehicle), the functional element is displaced along with the rotating shaft, creating a distance between it and the interior boundaries (i.e., components of the interior panels and internal components to which the functional element is attached). For example, the functional element could be an armrest attached adjacent to a passenger or driver's seat. The rotating shaft may also be displaced integrally into the interior of the passenger transport vehicle, whereby in one embodiment, the rotating shaft remains parallel to its initial position during this displacement. If the armrest rotates within the armrest assembly, space is required for this unless the armrest itself is perfectly rotationally symmetrical. The armrest frequently comes into contact with internal components. If the armrest's axis of rotation is temporarily raised for rotation, collisions with other components during rotation are avoided. After rotation, the axis of rotation, and in many cases the armrest along with the axis of rotation, can be moved back to its pre-rotation position. However, by rotating the armrest, the user can access a different surface area than before rotation. For this purpose, functional elements (e.g., armrests) may make one or more compartments or containers accessible in a first surface area and control panels and / or display panels accessible in a second surface area.

[0009] For example, one possible implementation involves a functional device of the above type in the form of a handrail, having a functional element in the form of a handrail having at least two separate surface areas, wherein the handrail is mounted in a bracket so as to be able to rotate and / or pivot about a horizontally aligned axis of rotation (e.g., in the direction of travel of a passenger transport vehicle), such that different surface areas can be accessed depending on the angle of rotation, wherein the axis of rotation or at least a portion thereof is movable in the vertical direction.

[0010] In this example, the handrail can thus rotate about a horizontal or nearly horizontal axis of rotation aligned in the direction of travel. For example, the handrail may cover a container located beneath it and be raised as a whole, for example, by half its width, before rotation. If the handrail rests directly on the container before rotation and the axis of rotation is located in the middle of the handrail in terms of width, then after the handrail has been raised by half its width using its axis of rotation, there is sufficient space under the handrail to allow it to rotate about its axis of rotation without contacting the container. In this case, the axis of rotation is also displaceable, thus in one embodiment, the axis of rotation remains parallel to its initial position. As mentioned above, the handrail may also be mounted at one end in a pivot bearing, such that it can rotate about the axis of rotation and pivot about a point in the region of the pivot bearing, thereby creating space for rotation.

[0011] For example, an armrest may have two distinct surface areas on its bottom and top sides, and each surface area may rotate 180 degrees. However, if the armrest has a prismatic cross-section and can rotate by an angle of 90 or 120 degrees, it may also have more than two surface areas, such as three or four surface areas.

[0012] Another possible embodiment relates to a functional device with a handrail having at least two movable handrail components, each having at least two separate surface areas and mounted in a bracket to be rotatable and / or pivotable about a horizontally oriented axis of rotation (particularly in the direction of travel of the passenger transport vehicle), wherein the axes of rotation of the different handrail components are aligned parallel to each other, and wherein the axes of rotation are movable in the vertical direction, particularly displaceable. As mentioned above, the axis of rotation can also be pivotable.

[0013] When it is mentioned in context that a rotating axis is movable, it means that the component that determines the corresponding rotating axis (such as a bearing) is movable accordingly.

[0014] In this case, the handrail may be divided into two or more strip-shaped handrail sections in its width direction, i.e., transverse to the direction of travel of the passenger transport vehicle, each strip-shaped handrail section having only a small width. Several handrail components in the handrail assembly each have an axis of rotation, and these components may rotate or pivot together about their axes of rotation, or rotate or pivot one after another, in order to present different surface areas to the user.

[0015] Each handrail component and its axis of rotation can be displaced in the manner described above before rotation to generate the distance required for rotation. If the handrail, or more generally the functional element, is divided into several handrail sections or functional element sections, the degree of displacement can be relatively small because the space required for rotation is significantly reduced when the functional element is separated.

[0016] It can also be configured such that the functional element covers a volume adjacent to the functional element, such as an accessible storage space below it, in at least one rotational and / or pivotal position.

[0017] In this configuration, the functional element may perform a covering function at least in a rotatable and / or pivotal position, covering a portion of the inner surface of the passenger transport vehicle. Simultaneously, some functions of the functional element on its side facing away from the interior may be inaccessible and obstructed from the user, while other functions are provided on the user-facing side. The covered volume may be a container, assembly, device, display, or control panel that can be used inside the passenger transport vehicle.

[0018] Furthermore, the functional element or a component of the functional element may be mounted in a pivot bearing at one or both ends of its two opposite ends of the axis of rotation, wherein in each pivot bearing, a first pivot bearing component is provided on the side of the functional element and a second pivot bearing component is provided on the side of the support, and wherein the second pivot bearing component is capable of moving inward and / or vertically upward.

[0019] With proper design, a pivot bearing at one end of the functional element may be sufficient and, for some applications, may provide adequate stability. However, in many cases, bearings at both ends of the rotating shaft will be helpful. Each pivot bearing has a first portion that is connected to the functional element and moves / rotates relative to a second portion of the pivot bearing. The second portion of the pivot bearing is attached to a support of the functional device (e.g., an armrest assembly). For example, the first portion of each pivot bearing may be the end of a shaft or short shaft that rotates in a bushing connected to the support that serves as the second portion of the pivot bearing. The first pivot bearing component may be directly supported on the second pivot bearing component, thus forming a sliding bearing. Additional rolling elements may also be provided, which are then positioned between the first and second bearing components. To displace the rotating shaft, the pivot bearing is then displaced. For example, in the case of an armrest assembly, the second pivot bearing component may simultaneously be displaced vertically upward by the same amount to temporarily raise the armrest.

[0020] Another possible implementation may be configured such that two separate, directly adjacent surface regions of a functional element or a portion thereof are separated from each other by a body edge or a rounded edge having a radius of curvature of less than 3 cm, particularly less than 1 cm, and / or the surface normals of the two directly adjacent, separate surface regions include an angle of at least 90 degrees.

[0021] To guide different surface areas toward passengers, these different surface areas are located in different circumferential regions of a functional element (e.g., an armrest) relative to the axis of rotation. The functional element may be divided into two or more circumferential regions. In many cases, these surface areas are angled relative to directly adjacent surface areas, thus providing an edge or curved area between adjacent surface areas. In most cases, no more than four surface areas will be provided, such that these surface areas are advantageously angled to each other at least about 90 degrees.

[0022] In another possible implementation, two separate, directly adjacent surface regions of a functional element or a portion thereof may be arranged opposite each other on different sides of the functional element.

[0023] In this configuration, the functional element (e.g., a handrail) is rotated approximately 180 degrees to change the surface area used. Regardless of the required rotation angle between different usage positions, a stop can be provided in which the functional element engages. For example, these stops can be incorporated into the design of a pivot bearing.

[0024] In a functional device, the rotational and / or pivotal movement of a functional element or a portion thereof may be linked by a transmission mechanism, such as gears, and the translational displacement movement of a rotating shaft (particularly two second pivot bearing components).

[0025] This linkage ensures that the functional element has the minimum distance required from the obstacle at each stage of its rotation.

[0026] In addition, or alternatively, the bracket or a portion thereof may be configured to pivot about a bracket axis extending parallel to the axis of rotation.

[0027] This design, in addition to the translational displacement of the rotation axis, allows for greater freedom of movement in the device, enabling functional elements to not only rotate around the rotation axis but also pivot with the support or other parts of the support. This means that the space beneath functional elements (e.g., armrests) can be utilized more extensively, or the rotation axis displacement required to rotate the functional elements can be smaller.

[0028] Another possible embodiment of the functional device may be configured such that the bracket has a fixed portion and at least one portion that is displaceable relative to the fixed portion, wherein the displaceable portion has a second pivot bearing component and is connected to the fixed portion via an elbow mechanism, wherein a first lever of the elbow mechanism is linked to the functional element such that rotation and / or pivoting of the functional element forces the first lever to pivot, and wherein a second lever is hinged to the first lever and the fixed portion of the bracket.

[0029] The first lever can, for example, be rigidly connected directly to the functional element itself. The movement of the first lever, performed together with the functional element during its rotation, forces the movement of the second lever, which represents a combination of pivoting movement and displacement, and produces displacement of the movable portion of the support relative to the fixed portion of the support. Thus, the rotational movement of the functional element, with its simple construction, immediately and inevitably produces displacement.

[0030] Alternatively, the first lever of the toggle mechanism can be securely connected to the second gear, which is driven by the first gear securely connected to the functional element and is capable of rotating about the rotation axis.

[0031] With the help of this structure, by appropriately selecting the dimensions of the first and second gears, the transmission mechanism can be easily designed to achieve the desired stroke / relative displacement of the movable part of the support relative to the fixed part of the support.

[0032] It can also be configured such that the functional element has at least one guide element spaced apart from the rotation axis and / or pivot axis, and that the guide element is guided on the guide surface or in the guide groove of the support when the functional element rotates and / or pivots about its rotation axis, thereby forcing the rotation axis and / or pivot axis to displace, in particular the second bearing component of the pivot bearing of the retaining device.

[0033] The guide element can be formed, for example, by the edge of the functional element / handrail, which slides on a fixed surface or edge of the support during rotational movement, thereby forcing the rotation axis of the functional element to translate / displace. The guide element can also be designed as a guide pin, which is guided in a slot on the support. This linked mechanical design is particularly simple and can be implemented with only a few parts.

[0034] Another embodiment may be configured such that the bracket has a fixed portion and at least one portion displaceable relative to the fixed portion between a first end position and a second end position, wherein the displaceable portion has a second pivot bearing portion. The fixed portion of the bracket may provide or form a guide for the displaceable portion. Individual displaceable portions of the bracket may also be provided in the fixed portion of the bracket at each end of the rotation axis; furthermore, the linkage of the various elements of the displaceable portions with each other may be configured such that their displacement movement is linked and synchronized via gears. This prevents the displaceable portions and functional elements of the bracket from tilting during displacement movement.

[0035] In this case, a spring device may optionally be provided in the functional device, which applies a force to at least one movable portion of the bracket in the direction of the first end position.

[0036] For example, a spring mechanism can push or pull the movable portion of the support into an end position where the functional element can rotate freely, i.e., move it inward toward the rotation axis of the functional element. In the example of the armrest, the suspension then moves the armrest and / or the rotation axis of the armrest to an upper end position corresponding to the first end position. After one rotation, the armrest can move back to the second end position against the spring force.

[0037] In addition, one or more movable portions of the bracket can be locked in a second end position opposite to the first end position.

[0038] In the example of the movable handrail, it can rotate to the upper end position and then move back to the lower end position against the force of the spring element and lock there.

[0039] It can also be configured such that one or more movable portions of the bracket can be alternately locked and unlocked on the fixed portion of the bracket by movement opposite to the force of the spring device.

[0040] Therefore, so-called push / push mechanisms are known, also referred to as "ballpoint pen mechanisms." The locking mechanism is activated by a first translational movement of the locking element, for example, overcoming a spring force, which is then deactivated by a second movement in the same direction. The locking element can then be moved out of the locked position by the spring force.

[0041] In addition to the functional device, the present invention may also relate to a method for actuating a functional device of the above type, wherein the rotation axis of the functional element or the rotation axis of a component of the functional element is first moved toward the interior of the transport vehicle, then the functional element is rotated about its rotation axis or a component of the functional element is rotated about its rotation axis, and then the one or more rotation axes are pushed back.

[0042] This method for rotating functional elements can be implemented simply and in a space-saving manner. Attached Figure Description

[0050] Furthermore, this utility model will be described based on exemplary embodiments shown in the accompanying drawings, and explained below.

[0051] Figure 1A perspective view of a functional device having a functional element 1 in the form of a handrail is shown. The handrail 1 is arranged above a volume 39 of a container it covers, such that the container is generally formed by the handrail. The handrail 1 has two opposing surface areas 1a and 1b, such that one of the surface areas is located on the upper side of the handrail and the other on the lower side. Figure 1 In the illustration, surface area 1a faces the vehicle interior 19, while surface area 1b faces the covered volume 39. The armrest 1 is mounted in brackets 7a and 7b to allow rotation about a rotation axis 13. A gap is left between the armrest and the wall of the container surrounding volume 39, allowing the armrest to rotate to a limited extent. Brackets 7a and 7b are movable in the vertical direction indicated by arrow 20, so as to simultaneously displace the rotation axis 13 and additionally create space for the armrest 1 to rotate fully about the rotation axis 13. As long as the armrest 1 is not rotating, it can be lowered to the wall of the container surrounding volume 39. To allow the armrest 1 to rotate about the rotation axis 13, brackets 7a and 7b are then raised in the direction of arrow 20, so as to lower again after rotation.

[0052] Figure 2 The handrail 1 is shown in its central position during rotation, with surface regions 1a and 1b vertically aligned.

[0053] Figure 3 It shows the relationship with Figure 1 The state shown is compared to the armrest shortly before it completed a 180° rotation, with arrow 35 indicating the direction of rotation.

[0054] exist Figure 3 In the middle, it can be seen that the support pad 36 is arranged on the surface area 1b of the handrail 1, and as Figure 1 As is clearly visible, surface area 1a is smooth. Therefore, surface area 1b, which has a support pad 36 for the passenger's arm, can point towards the top of the passenger compartment / interior to increase travel comfort, while surface area 1a can be used, for example, to store objects such as drinking containers during rest periods.

[0055] Figure 4 Another configuration of the armrest 2 with surface region 2a having a groove for storing objects is shown, while on the opposite side of the armrest, surface region 2b can be smooth and flat. The armrest 2 is rotatable about a rotation axis 14, which extends horizontally and parallel to the vehicle's direction of travel. The armrest 2 is rotatably mounted in two pivot bearings of brackets 8a and 8b. On the bracket 8a side, the fixed portion 108b and the movable portion 108a of the bracket 8a are shown in detail. The movable portion 108a and its corresponding portion on the bracket 8b side are movable in the vertical direction, as indicated by arrow 20, so that the armrest 2 can also be raised with the rotation axis 14. The armrest 2 can then be rotated, as... Figure 4As shown, this prevents it from contacting the wall of container 49. After the handrail 2 rotates 180° around the horizontal axis 14, the movable portion 108a of the supports 8a and 8b can be lowered again, and the handrail 2 can rest on the edge of container 49.

[0056] Figure 5 A mechanism is shown in more detail that links the rotation of the armrest 2 about the axis 14 with the lifting of the rotation axis 14 or the pivot bearing in which the armrest 2 is mounted. For this purpose, a pivot bearing component is arranged in a movable / displaceable portion 108a of the bracket 8a, and the displaceable portion 108a of the bracket 8a is displaced into a fixed portion 108b of the bracket. The pivot bearing portion within the displaceable portion 108a of the bracket can, for example, be a housing for a main shaft. In the armrest 2, a mandrel is then provided at each of its ends, the longitudinal axis of which extends in the direction of the rotation axis 14. A pivot pin then forms a mandrel component, which is displaced into the pivot bearing portion of the displaceable portion 108a of the bracket.

[0057] Rollers 27 and 28 are provided on the outer edges of the portions of the armrest 2 facing the support. These rollers can roll on the guide surface 29 of the fixed portion 108b of the support 8a. Instead of, for example, rotatably mounted rollers 27 and 28, a curve in the armrest can be provided, which can slide on the guide surface 29.

[0058] If the armrest 2 rotates about its longitudinal axis / rotation axis 14, the rollers 27 or 28 roll on the guide surface 29 in a direction perpendicular to the rotation axis 14, thereby... Figure 4 As shown, the handrail 2 rises together with the rotation axis 14. This is possible due to the movable arrangement of the movable portion 108a of the support 8a.

[0059] If the handrail 2 returns to the horizontal position after rotating 180° or 360°, it can be lowered again using the pivot bearing assembly and shaft 14. The surface areas of the handrail 2 are indicated by 2a and 2b.

[0060] exist Figure 4 and Figure 5 In the figure, reference numeral 19 indicates the interior of the vehicle arranged above the functional element 2 in the form of an armrest.

[0061] In the bracket 8a, a spring device 30 with a helical spring and a spring guide is shown, wherein the helical spring is supported in the fixed portion 108b of the bracket 8a and presses upward on the movable portion 108a of the bracket. For example, in the stationary state, the movable portion 108a is locked in its lower position and can be unlocked by rotating the armrest 2. However, it can also be configured such that the spring force is insufficient to lift the armrest alone, and the spring force supports the rotation of the armrest only by a portion of the weight of the armrest lifted by the spring force.

[0062] Figure 6 and Figure 7 Two-piece handrails 3 are shown, each with two parallel components 3a and 3b. Each of components 3a and 3b is rotatable about its own axis of rotation 15, so as to rotate surface areas 3c and 3d to the top or bottom, respectively. Components 3a and 3b each have a pivot pin 21 located on the extension of the axis of rotation 15 and mounted in a pin receiving component 22 of the movable portion of the brackets 9a and 9b.

[0063] Figure 8 A functional device with a stylized handrail-like functional element 4 is schematically shown, rotatably mounted at both ends in a portion of supports 10a and 10b. The axis of rotation of the handrail 4 is indicated by 16, and it extends horizontally in the direction of travel or movement of the vehicle or transport vehicle. Figure 8 The handrail shown has surface area 4a facing upwards toward the interior of the vehicle 19, while on the lower side of the handrail, surface area 4b faces toward the container located below the handrail. For clarity, the container is... Figure 8 Not shown in the image.

[0064] The support frame has two parts 10a and 10b, one of which is located at each end of the handrail. Each of the two parts 10a and 10b has a second pivot bearing component in the form of a receiving portion, each receiving portion accommodating the spindle of the handrail, the axis of rotation of which is arranged coaxially with the axis of rotation 16. The movable portion 110a of the support frame is arranged to be able to displace vertically relative to the fixed portion 110b. The fixed portion 110b forms a guide rail for guiding the linear movement of the movable portion 110a upward in the direction of arrow 20 and downward in the opposite direction. On both sides of the handrail 4, in the region of the pivot bearing, there are movable portions of the support frame that are guided into the fixed portion of the support frame by displacement.

[0065] exist Figure 9 In the middle, handrail 4 (in principle already) Figure 8 (As shown in the image) are displayed at different rotation angle positions. Figure 8Compared to the rotational position shown, the surface areas 4a and 4b of the armrest 4 have rotated approximately 70° around the rotation axis 16. Meanwhile, it is shown that linkage gears are provided in the areas of the supports 10a and 10b at both ends of the armrest, which link the rotation of the armrest 4 around the rotation axis 16 with the linear displacement of the movable portion 110a relative to the fixed portion 110b of the support.

[0066] exist Figure 10 In the middle, on one side of the handrail 4, a linkage mechanism is shown in detail and in cross section. This mechanism links the rotational movement of the handrail 4 about the rotation axis 16 with the linear up-and-down movement of the movable part 110a of the support 10a.

[0067] The first gear 25 is rotatably fixed to the armrest 4, and the two components mentioned are rotatably mounted on the movable portion 110a of the bracket 10a, such that rotation of the armrest 4 about the rotation axis 16 causes rotation of the first gear 25 about the same rotation axis. The first gear meshes with the second gear 26, which is rotatably mounted on the movable portion 110a of the bracket 10a. The first elbow 23 is securely connected to the second gear 26 and pivots together with the second gear 26 when the armrest 4 rotates. The first elbow 23 is connected to the first end of the second elbow 24 in the pivot joint 50, and when the armrest 4 rotates, the second elbow simultaneously displaces and pivots due to the first elbow 23. Since the second end of the second elbow 24 is rotatably linked to the fixed portion 110b of the bracket 10a along the rotation axis 51, as the handrail 4 rotates away from the horizontal alignment of the surface areas 4a, 4b, the movable portion 110a moves upward along with the handrail itself in the direction of arrow 20. Simultaneously, the rotation from the vertical alignment of the surface areas 4a, 4b towards the horizontal alignment causes a downward displacement of the handrail and the rotation axis 16. By linking the rotational movement with the translational movement, when the handrail rotates about the rotation axis 16 from its rest position, the handrail is raised so that it can rotate freely without touching, for example, an object directly resting on its rest position.

[0068] After the handrail has rotated, due to the corresponding design of the linkage gear, the handrail returns to its initial resting position after completing a rotation angle of 180° or an integer multiple thereof.

[0069] Figure 11 , Figure 12 and Figure 13 The previous view, shown in a side view, is positioned at different rotation angles. Figure 8 , Figure 9 and Figure 10 The handrail structure has already been shown.

[0070] exist Figure 11In the center, the armrest 4 is in a horizontal position, such that the two surface areas 4a and 4b are horizontally aligned, and the upper surface area 4a faces the interior 19 of the vehicle. The axis of rotation is indicated by 16, and the portion of the bracket on the structural side facing the observer is indicated by 10a, where 110b represents the fixed portion of the bracket 10a, and 110a represents the portion that can move linearly relative to the fixed portion 110b.

[0071] Figure 12 The rotation angle position of armrest 4 is shown, where it is related to... Figure 11 Compared to the state shown, the armrest 4 rotates approximately 45° counterclockwise (i.e., in the direction of arrow 52). Due to the gear ratio of the first gear 25 and the second gear 26, the first elbow 23 moves in the direction of arrow 53 during this movement, and thus presses down on the second elbow 24 in the direction of arrow 54, or presses up on the movable portion 110a of the bracket along with the armrest 4 relative to the second elbow 24. The armrest 4 thus moves upward in the direction of arrow 20, while simultaneously moving in the direction of rotation of arrow 52, ​​allowing it to utilize the space released below it for rotation.

[0072] exist Figure 13 In the diagram, the armrest 4 is shown as being rotated further in the direction of arrow 52, ​​such that in this position, the movable portion 110a is almost fully displaced upward relative to the fixed portion 110b of the support 10a. The dimensions of gears 25 and 26 and the lengths of elbows 23 and 24 are adjusted to each other such that in the vertical position of the armrest (i.e., when surfaces 4a and 4b are vertically aligned), the maximum upward travel of the armrest in the direction of arrow 20 is achieved, and further rotation causes the elbows to move in the opposite direction and the armrest to lower.

[0073] For example, the mechanism for rotating the handrail can be configured to be manually operated by gripping the handrail itself and linked to the rotational movement, causing the handrail to rise automatically. However, the rotation of the handrail can also be motorized, i.e., driven by an electric motor, which then only requires the rotation of the handrail itself to be driven, while the up-and-down movement of the handrail is linked to the linear displacement of the movable part of the support.

[0074] exist Figure 14 and Figure 15In the diagram, the handrail is again shown schematically and is designated as 5. The handrail 5 has a first upper surface region 5a facing inwards 19 and a lower surface region 5b opposite to the upper surface region 5a, which, in its resting position, faces the volume 39 of the container covered by the handrail. The handrail 5 is also provided with supports 12a and 12b, each support having a support member at its two opposite ends aligned with the rotation axis 17, wherein supports 12a and 12b also each have a movable portion 112a and a fixed portion 112b. The movable portion 112a can move linearly within the fixed portion 112b, allowing the handrail 5 to move upwards in the direction of arrow 20 and translate in the opposite direction. However, compared with… Figures 8 to 13 Compared to the previous implementation, the fixed portion 112b of the support 12a is fixed only in the sense that it cannot be translated. However, the fixed portion 112b of the support is capable of pivoting about the support axis 32.

[0075] Therefore, the handrail 5 can pivot about axis 32 together with the supports 12a and 12b, while simultaneously rotating and displacing in the direction of arrow 20, as shown by arrow 21. Due to the additional degree of freedom gained by pivoting in the direction of arrow 21, the space beneath the handrail 5 can be used even more effectively for different rotational angular positions. For example, if the handrail only needs to be slightly raised to access the space beneath it, the largest possible opening for access to volume 39 can be created by displacing and pivoting the supports 12a and 12b with minimal force. During the full rotation of the handrail 5, the pivotability of the supports 12a and 12b can be used to achieve full rotation of the handrail above the volume 39 it covers, wherein the displaceable portion 112a of the supports has a small relative displacement compared to the fixed portion 112b.

[0076] Figure 16 , Figure 17 , Figure 18 , Figure 19 A handrail assembly with handrails 6 is schematically shown, which are rotatably mounted in brackets 11a at both ends. In the figure, the axis of rotation of the handrail 6 is indicated by 18.

[0077] The accompanying drawing shows only one side of the handrail with the support 11a. Also in this case, as in the other embodiments shown, the handrail 6 with the axis of rotation 18 can move linearly up and down. This is achieved in the example shown, where the support 11a has a movable portion 111a that can move up and down within the fixed portion 111b. With the movable portion 111a of the support 11a moved upward in the direction of arrow 20, the handrail 6 is then able to rotate about the axis of rotation 18 and reach its lowest point after rotating 90°, displacing upward so far that it does not come into contact with, for example, a container arranged below the handrail 6.

[0078] exist Figure 16 In the image, the handrail 6 is shown in a rotational angle position, in which it is rotated approximately 70° relative to the horizontal position pointing upwards from the surface area 6a.

[0079] exist Figure 17 In the diagram, the armrest 6 is shown in a use position, in which surface area 6a points upward and faces inward 19. Various recesses are visible in surface area 6a, which may form shelves for placing items, for example. In a position rotated 180° about the axis of rotation 18, surface area 6b faces upward toward inward 19 and may provide, for example, a flat surface or a padded armrest.

[0080] Figure 18 The interaction between the movable portion 111a and the fixed portion 111b of the support 11a is shown in more detail.

[0081] Figure 19 A further enlarged front view of the mechanical structure of the fixed part 111b is shown in particular. Figure 19 In the figure, reference numeral 30 indicates a roller spring, which represents a spring device that pushes the movable portion 111a of the bracket 11a upward in the direction of arrow 20. Reference numeral 55 indicates a link in the fixed portion 111b, in which the fingers 57 of the movable portion 111a are guided for a push-push mechanism. This mechanism, known per se, has the effect that when the movable portion 111a is pressed downward against the force of the spring 30 in the direction opposite to arrow 20, the movable portion can be locked in its lowest position and can be unlocked again by further downward pressing so that it can then be pressed upward by the force of the roller spring 30. 56 indicates a synchronizing link that ensures that the roller springs 30 arranged on both sides of the central axis of the movable portion 111a are tensioned and relaxed synchronously, and prevents the movable portion 111a from tilting in the fixed portion 111b.

[0082] In the lower part of the fixed portion 111b, two dampers 58 are provided to inhibit the movement of the movable portion 111a. Synchronizing gears 59, which move together with the roller springs during tensioning and relaxation, are used to synchronize the tensioning and relaxation movements of the roller springs through their linkage, and thus prevent jamming. The gears 59 are connected to each other via a synchronizing shaft 60. Finally, a stop damper 61 is provided at the end of the movement path of the movable portion 111a.

[0083] In order to use Figures 16 to 19The mechanism shown first applies downward pressure to the armrest 6 in its resting position to release the locking mechanism via a push-push mechanism and allow the roller springs 30 to move. By releasing the tension, they push the movable portion 111a of the bracket 11a upward, giving the armrest 6 a 180° degree of freedom to rotate about its axis of rotation 18. After rotation has occurred, the armrest 6 is then pressed downward against the force of the roller springs 30 until it engages in the locking device. Different surface areas of the armrest 6 are then available for use.

[0084] Figures 20 to 24 A perspective view of a functional device having functional elements 1 in the form of armrests in different positions is shown. The armrests 1 are arranged above the volume 39 of the container 200 they cover, thus forming a container generally covered by the armrests. The armrests 1 have two opposing surface areas 1a and 1b, such that one surface area is located on the upper side of the armrest, and the other on the lower side. Figure 20 In the illustration, surface region 1a faces the vehicle interior 19, while surface region 1b faces the coverage volume 39. Figure 23 In the representation, it is the opposite. The handrail 1 is rotatably mounted in a pivot bearing 201 within a support 202 about a rotation axis 13. To create the space required for rotation between the wall of the container 200 and the handrail 1, the handrail can pivot about a point on the support 202 located in the region of the pivot bearing 201, for example, about a horizontal axis 203, such that the rotation axis 13 can also pivot about that point or axis into the interior 19 and is therefore movable. For example, as... Figure 22 and Figure 24 As shown, the handrail 1 can pivot 90 degrees into a vertical position, so that the axis of rotation 13 is also vertically aligned. In this position, or in an intermediate position between the vertical and horizontal positions, the handrail can then rotate, for example, 180 degrees about its axis of rotation 13. Figure 21 The image shows such a location.

[0085] Figure 24 A position is shown where, with the rotation axis 13 in a vertical position, and... Figure 22 Compared to the position shown, the handrail has rotated more than 90 degrees around the rotation axis 13.

[0086] In order to enable all the above-mentioned rotational and pivotal movements, the pivot bearing 201 may be designed, for example, as a ball joint.

[0087] This invention provides a simple mechanism that allows functional elements to rotate within a transport vehicle with minimal space requirements. In addition to the handrail, another functional element (e.g., a display device on a dashboard) can be mounted in a movable bracket and moved inwards to allow for rotation and retraction.
