Description

Technical area

The invention relates to a height-adjustable platform, in particular to a height-adjustable platform for forming mobile stops.

State of the art

The concept of accessibility is playing an increasingly important role in urban planning. Accessibility means designing public infrastructure, such as public facilities, buildings, squares or means of transport, so that they are as easily accessible as possible for all social groups, regardless of their impairments. Particularly in the area of local public transport, which is often a preferred means of transport for people with physical disabilities, such as seniors, the barrier-free design of vehicles and stops is becoming increasingly important.

It is known that the interface between the physical infrastructure, such as a stop or a platform, and the vehicle is crucial for barrier-free use of means of transport. It is therefore not surprising that the design of this interface is the subject of standardization, for example DIN 18040-3, and national and international legislation. This shows that good accessibility for all population groups is becoming increasingly important when building both private and public infrastructure.

In order to improve accessibility in public spaces, guidance systems are provided for blind and visually impaired people, which enable them to easily, often tactilely, orient themselves. For the same reason, visual and acoustic information providers, such as acoustic signals at traffic lights or announcements or display boards at stops, can be provided. Furthermore, attempts are often made to make public spaces as free of steps as possible so that wheelchair users, people pushing strollers or generally people whose mobility is limited can move around with as little disruption as possible.

If the above-mentioned structural infrastructure is designed to be barrier-free at the planning stage, the concept of accessibility can be implemented relatively easily. However, it is much more difficult if existing facilities that are not barrier-free are to be converted to be barrier-free. A variety of complex renovation work is often necessary here, which results in high costs that are often not amortized.

Due to the high costs, the barrier-free design of temporarily installed infrastructure, such as replacement stops, is particularly problematic. Undoubtedly, there is a need for easy accessibility for temporarily installed stops as well as for permanently installed stops. In particular, it is crucial that the height of a temporarily installed stop platform is adapted to the entry height of a vehicle in order to avoid unnecessary steps that would make access to the vehicle difficult.

However, in the solutions known in the prior art, this is only possible through complex technical measures that cause disproportionately high costs. Alternatively, more cost-effective solutions are known, but this results in limited functionality and thus a deterioration in accessibility. The previous solutions offer approaches, but these remain piecemeal and always have to be elaborately supplemented in order to achieve functionality. A mobile infrastructure that ensures accessibility, in particular a stepless construction, and that can be set up and dismantled with little effort and can be expanded in a modular manner does not yet exist.

To solve the problems presented above, for example, suggests: DE 102 02 364 A1 a multifunctional, transportable piece of street furniture with a protective function. The segmented street furniture comprises a substantially rectangular floor frame with longitudinal and/or transverse stiffeners for holding covering panels. It further comprises a hollow profile support structure located on the base frame corners and extending vertically upwards, receptacles oriented laterally and horizontally from the base frame for lining up further frames or frame segments and/or for receiving a ramp.

That in the DE 102 02 364 A1 The segment street furniture described, in which feet with a spindle adjustment are arranged at the corners, has the disadvantage that the spindle of the spindle adjustment extends upwards from a surface. The upwardly projecting spindle adjustment prevents a completely flat surface from being formed. In addition to the fact that this can cause people to stumble, it can also affect accessibility for people with limited mobility, such as wheelchair users. In addition, the permanently installed post con structure the modular expandability of the segmental street furniture.

Despite the solutions known from the prior art, there is still a need for platforms that are height-adjustable, can be easily assembled and dismantled and are therefore reusable, can be modularly expanded as flexibly as possible and enable barrier-free access.

Presentation of the invention

This is where the invention comes into play. The aim is to provide a platform that is height-adjustable, easy to assemble and dismantle, can be flexibly expanded in a modular manner and enables barrier-free access. This object is achieved according to the invention by the height-adjustable platform according to independent claim 1 and by the height-adjustable arrangement according to claim 8. Further advantageous aspects, details and refinements of the invention result from the dependent claims, the description and the drawings.

The present invention provides a height-adjustable platform having at least one base element, the base element having a base frame and a base insert plate. The base frame has a first base frame longitudinal strut, a first base frame cross strut, a second base frame longitudinal strut opposite the first base frame longitudinal strut, and a second base frame cross strut opposite the first base frame cross strut. The base frame longitudinal struts and the base frame cross struts are firmly connected to one another and separate a base element interior from a base element exterior. A base frame longitudinal strut and a base frame cross strut each form a corner of the base frame. In the corners of the base frame, a height-adjustable foot is arranged on at least one base frame longitudinal strut and/or on a base frame cross strut for supporting the base frame against a surface. Each of the base frame longitudinal struts and each of the base frame cross struts has at least one receiving element on an outer surface facing the base element outer space. At least the first and second base frame longitudinal struts or the first and second base frame transverse struts have, on their respective inner surfaces facing the base element interior, a support for supporting the base insert plate that can be arranged in the base element interior. The base insert plate forms a common base element surface facing away from the base with an upper edge of the base frame that runs around the entire base frame and faces away from the base.

Since the base insert plate forms a common surface together with the upper edge of the base frame, no elements or components of the base element protrude beyond the surface formed. Consequently, a base element has a substantially flat surface from which no objects protrude. Advantageously, obstacles that could cause people to stumble or restrict people's mobility are eliminated.

A transverse strut of the base frame and a longitudinal strut of the base frame are each firmly connected to one another in the area forming the corner. The corners preferably enclose a 90° angle, but can also enclose a larger or smaller angle. In this case, the base frame has the shape of a parallelogram when viewed from above. The length of the base frame cross struts can correspond to the length of the base frame longitudinal struts. In this case, the base frame has the shape of a square when viewed from above. If a different length is chosen for the cross struts and longitudinal struts of the base frame, the frame can be designed in any shape. This provides a stable frame geometry that is adapted to the requirements at the site of use.

The receiving elements of the base frame are preferably designed in the form of eyelets or pockets. However, the receiving elements can also be designed as grooves, depressions or bores. More than one receiving element, for example an even or an odd number of receiving elements, can be arranged on a strut. These can, for example, be arranged symmetrically to a center of the strut. The receiving elements are preferably arranged in the same position on all four struts, so that the base frame can be easily assembled regardless of its orientation.

The supports provided on the inner surfaces of the struts of the base frame to support the base insert plate that can be arranged in the interior of the base element can in principle be of any design. For example, strips can be attached to the struts that extend over the majority of the extent of the respective strut. However, several shorter strips can also be provided. It is also conceivable to use hook elements that are attached to the respective strut, for example suspended, and that engage in corresponding recesses in the base insert plate. The supports can also be made as an integral part of the struts be formed, for example a leg of a strut with an L-shaped cross section can serve as a support.

The supports on the inside of the struts of the base frame are formed on at least two opposite longitudinal or transverse struts of the base frame. Of course, the supports can also be formed on both the longitudinal and cross struts of the base frame, for example if particularly stable support for the base insert plate is required. In order to prevent the base insert plate from being lifted off the supports and thus advantageously form a particularly stable and safe construction, the base insert plate can be fixed to the supports or to the struts.

In a preferred embodiment of the height-adjustable platform, at least one extension element is additionally provided. The extension element has an extension frame and an extension insert plate. The extension frame has a first extension frame longitudinal strut, a first extension frame cross strut, a second extension frame longitudinal strut opposite the first extension frame longitudinal strut, and a second extension frame cross strut opposite the first extension frame cross strut. The expansion frame longitudinal struts and the expansion frame cross struts are firmly connected to one another and separate an expansion element interior from an expansion element exterior. One extension frame longitudinal strut and one extension frame cross strut each form a corner of the extension frame. In at least two mutually adjacent corners of the extension frame, which are connected to one another by an extension frame longitudinal strut or an extension frame cross strut, a height-adjustable foot is arranged on at least one extension frame longitudinal strut and/or on an extension frame cross strut for supporting the extension frame against the ground. On an outer surface of the extension frame longitudinal strut or the extension frame cross strut facing the extension element exterior, which is opposite the extension frame longitudinal strut or extension frame cross strut connecting the two mutually adjacent corners of the extension frame, in each of which a height-adjustable foot is arranged, there is at least one engagement element that is complementary to the at least one receiving element of the base frame arranged.

At least the first and second extension frame longitudinal struts or the first and second extension frame cross struts have, on their respective inner surfaces facing the extension element interior, a support for supporting the extension insert plate that can be arranged in the extension element interior. The supports can be designed as described for the base frame. The extension insert plate forms a common extension element surface facing away from the ground with an upper edge of the extension frame that runs around the entire extension frame and faces away from the ground.

The engagement element that is complementary to the at least one receiving element of the base frame is arranged and designed in such a way that the base element surface and the extension element surface form a common platform surface when the engagement element engages in the receiving element.

Similar to the common surface formed by the base insert plate together with the upper edge of the base frame, the extension insert plate and the upper edge of the extension frame also form a common surface from which no elements or components of the extension element protrude. The surface of the extension element therefore does not have any obstacles that could cause people to stumble or that could restrict people's mobility.

The above explanations regarding the base insert plate and its inclusion in the base frame are also applicable to the extension insert plates and their inclusion in the extension frame.

If the at least one receiving element of a base frame strut is connected to the at least one engagement element of an extension frame strut in order to connect a base element to an extension element, the surface of the base element and the surface of the extension element form a common platform surface. Even after assembly, no element protrudes from the platform surface. Advantageously, a modularly expandable platform is created that has a flat surface that is free of obstacles and therefore barrier-free.

The receiving elements and the engagement elements can be designed to be complementary, so that as soon as they engage with one another, they limit the mobility of the base element with respect to the extension element. Preferably, the receiving elements of the base element provide a support function for the engagement elements of the extension element, so that one on the Force acting on the extension element surface can be derived via the engagement elements to the receiving elements. In this way, modularly expandable, stable platforms can be built that can reliably support loads acting on the surface against the subsurface.

The receiving elements and engagement elements can be formed, for example, as a hook and eye, tongue and groove, dovetail pairing, claw and pocket, latching or snap connection, pin or bolt connection, or as another suitable connection, possibly also as a combination of those listed above. Depending on the application, a stable connection between basic elements and extension elements is provided.

Of course, the statements made about the geometry of the base frames also apply to the geometry of the extension frames. The extension frames can have a different geometry than the base frames. However, the extension frames are preferably designed to be largely identical to the base frames. They only differ in that the receiving elements on an extension frame strut are replaced by engaging elements. Because the engagement elements are suitable for ensuring support of the extension element against the receiving elements of a base element, height-adjustable feet on this extension frame strut can be omitted. This simplifies the construction of the extension elements and thus reduces the production costs and the assembly effort, while the stability of a construction made up of base elements and extension elements is still maintained.

The engagement elements are preferably arranged on the outside of an extension frame strut in such a way that their position corresponds to the position of the receiving elements on an outside of a base frame strut. The engagement elements engage in the receiving elements when a base element is to be connected to an extension element.

If a gap is formed between the base elements and the engagement elements when connecting them, this gap is preferably negligibly small within the scope of the manufacturing and assembly tolerances. This has the advantage that the uniformity of the platform surface formed is not broken up by gaps. This makes it almost impossible for rod or stick-like objects, such as canes for the blind, or tires, for example from wheelchairs, to slip into the gap and get stuck there. This further improves accessibility.

According to the invention, a height-adjustable platform can be expanded with additional attachments in addition to base elements and extension elements. For example, ramps provided with engaging elements can be connected to the receiving elements provided on the base elements and extension elements in order to enable stepless access to the height-adjustable platform.

The height of the height-adjustable feet of the base element and/or the extension element can be adjusted independently of one another to the surface, in particular to uneven terrain. A platform according to the invention can therefore be leveled even on uneven surfaces by individually adjusting the feet. Alternatively, an inclination of the platform can be adjusted by adjusting the feet accordingly, which may be necessary, for example, to drain liquids such as rainwater.

In a preferred embodiment, at least one of the height-adjustable feet for supporting the base frame and/or at least one of the height-adjustable feet for supporting the extension frame is designed as a three-joint foot. The three-joint base has a first leg, a second leg, a first axle, a second axle, a third axle and a setup element intended for placement on the ground. A holding element is provided for connecting the three-joint base to the base element or the extension element. A first end of the first leg and a first end of the second leg are articulated to one another by means of the first axis, the first axis being arranged adjacent to the erection element. A second end of the first leg facing away from the setting element is connected to the holding element in an articulated and fixed position with respect to the holding element by means of the second axis. A second end of the second leg facing away from the setting element is connected to the holding element in an articulated and position-variable manner with respect to the holding element by means of the third axis.

In the context of the present invention, the term “fixed position” means that a translational movement of a “fixed position” element is excluded. If one end of a leg is connected to a holding element in a “fixed position”, the leg can rotate relative to the holding element, ie the leg can carry out a rotational movement. But the end of the leg is trans latory position relative to the holder cannot be changed, ie it is fixed in position.

Following this, in the context of the present invention, the term “position-variable” means that a “position-variable” element can perform both a rotational and a translational one.

Due to the articulated connection of the two legs, a movement of the second end of the second leg in the direction of the second end of the first leg leads to a rotation of the first leg. A change in position of the second end of the second leg changes the distance between the first axis and the holding element. Because the first axis is arranged adjacent to the holding element, the height of the three-joint base can be adjusted by changing the position of the second end of the second leg. At this point there will be no detailed explanation of how a three-joint foot works. Instead, please refer to the description of the figures to explain the basic functional principle.

In an alternative preferred embodiment, the three-joint base has a first leg, a second leg, a first axis, a second axis, a third axis, a fourth axis, a fifth axis, a first set-up element intended for setting up on the ground and a second for setting up the installation element provided on the surface. A holding element is provided for connecting the three-joint base to the base element or the extension element. A first end of the first leg is articulated to the first setup element by means of the fifth axis and a first end of the second leg is articulated to the second setup element by means of the fourth axis. A second end of the first leg facing away from the first setting element is connected to the holding element in an articulated and fixed position with respect to the holding element by means of the second axis. A second end of the second leg facing away from the second setting element is connected to the holding element in an articulated and position-variable manner with respect to the holding element by means of the third axis. The first leg and the second leg are connected to one another in an articulated manner by means of the first axis.

The functionality of the three-joint base described here corresponds to that of the previous exemplary embodiment. Only the first axis does not connect the first ends of the first and second legs, but rather a different area of the two legs. This makes it possible to provide a second set-up element in comparison to the previously described exemplary embodiment. This increases the footprint of the height-adjustable platform, which leads to better load distribution on a flat surface.

Regardless of the specific embodiment of the three-joint base, the stand element can be fixed as a separate component at one end of a leg or on the first axis. Preferably, the setup element can be connected to the three-joint base by means of a swivel or ball joint, so that uneven floors can be compensated for by pivoting the setup element. This allows the platform to be set up safely even on uneven surfaces. Alternatively, the setup element can be an integral part of a leg or the first axis.

Each of the feet is preferably designed as a three-joint foot. Three-joint feet have the advantage that they do not protrude from the top of the platform in any state, neither folded nor extended. Rather, three-joint feet have a small height when folded, which is largely determined by the dimensions of the holding element and the width of the legs. This ensures the accessibility of the height-adjustable platform. At the same time, the stackability of base elements and extension elements according to the invention is improved.

The holding element is preferably attached to a base frame longitudinal strut or a base frame cross strut of the base frame or to an extension frame longitudinal strut or an extension frame cross strut of the extension frame. The holding element has a cross-section perpendicular to the strut to which the holding element is attached, a substantially U-shaped profile with a web and two flanges connected to one another by the web and protruding essentially at right angles to the web. The holding element is fastened in a corner of the base frame or the extension frame in such a way that the flanges are oriented towards the mounting element. The second axis and the third axis are oriented essentially parallel to the web and perpendicular to the two flanges, with the second end of the first leg being connected to the flanges in an articulated and fixed position with respect to the holding element by means of the second axis. The second end of the second leg is connected to the flanges in an articulated and position-variable manner with respect to the holding element by means of the third axis.

According to this embodiment, the web of the U-profile limits the height-adjustable foot in the direction of the top of the platform The bridge does not protrude beyond the top of the platform, but can be hidden, for example, under one of the insert plates. Alternatively, the web can be flush with one of the insert plates and thus form part of the surface of the platform. The height-adjustable feet enable reliable height adjustment of the height-adjustable platform, while at the same time maintaining the accessibility of the platform. Furthermore, the web and the flanges of the holding element are suitable for protecting the legs and axles from damage, particularly when the three-joint feet are retracted.

The axles can be attached to the flanges in a form-fitting, non-positive or material-locking manner. By guiding the axles on both sides, tilting of the axles is prevented and force is introduced symmetrically into the holding elements when loads are supported against a surface by the height-adjustable platform.

Further preferably, a first flange of the holding element is designed as a perforated rail with a plurality of holes arranged in a row running parallel to the strut to which the holding element is attached, and a second flange of the holding element is designed as a wave rail. The wave rail has wave troughs and wave crests, the wave troughs of the wave rail being arranged in alignment with the holes in the perforated rail. The second axis penetrates a hole in the perforated rail in a fixed position and is arranged in a wave trough of the wave rail. The third axis can be brought into engagement with the shaft rail by a movement of the second leg in such a way that the third axis is arranged in a wave trough of the wave rail and that the third axis penetrates the hole in the perforated rail that is aligned with the wave trough.

This enables guidance and locking of the third axis in particular when the height of the three-joint base is adjusted by moving the second leg. The axle is caught in the troughs and is thus pre-positioned in the holes aligned with the troughs, which simplifies the height adjustment and assembly of the height-adjustable platform.

With a view to a particularly comfortable adjustment of the height of the platform relative to the ground, a slot or a series of holes aligned with the holes in the perforated rail can be provided in the web of the holding element. The position of the third axis becomes visible through these openings. By attaching a scale to the top of the bridge, a height position of the platform can be assigned to the holes in the perforated machine. This makes it possible to check the position of the third axis not only haptically but also visually when setting up the platform and to bring all feet into a predetermined setting.

More preferably, each of the flanges can have both a perforated rail and a wave rail. For this purpose, the flanges can, for example, be double-walled or be deflected at an end pointing away from the web in such a way that a perforated rail is formed in a continuous flange section leading away from the web and a wave rail is formed on the flange section following the deflection and pointing towards the web, the wave troughs of which are formed are arranged in an extension of the holes in the perforated rail. Advantageously, the axis can be supported and guided symmetrically in this way.

In a preferred embodiment, at least one base cover plate and/or at least one extension cover plate is provided, wherein the at least one base cover plate is designed to be arranged on the base insert plate and the at least one extension cover plate is designed to be arranged on the extension insert plate. The at least one base cover plate and/or the at least one extension cover plate has a surface texture with anti-slip and/or tactile properties. Additionally or alternatively, holes for rainwater drainage are provided in the at least one base cover plate and/or the at least one extension cover plate.

“Surface texture” is defined in the sense of the invention as a specific quality of a surface that serves to fulfill a specific purpose.

Through the modular provision of cover plates, the platform can be adapted, if necessary even in sections, to the requirements prevailing at the site of use. This is suitable for improving the modularity and accessibility of the platform.

The invention further relates to height-adjustable arrangements which have at least one height-adjustable platform. In addition, at least one connecting element is provided, the connecting element having a base body and at least two connecting elements that are complementary in arrangement and shape to the receiving elements of the base frame and to the receiving elements of the extension frame. The receiving elements are arranged on opposite sides of the base body in such a way that the connecting elements engage in the Receiving elements base frame and / or extension frame can be connected to one another.

Using connecting elements, height-adjustable platforms can be combined to form height-adjustable arrangements. The height-adjustable platforms are formed from a series of basic elements and extension elements. These rows are then connected by means of the connecting elements to form extensive, height-adjustable arrangements.

The functionality of the connecting elements is comparable to a socket/socket adapter known from the field of electrical engineering, which is used to connect two similar plugs. This means that receiving elements of adjacent base elements and/or extension elements can be connected according to a negative-positive-positive-negative principle by means of the connecting elements arranged on the connecting elements. In this way, various elements can be connected in any combination to form a height-adjustable platform and the modularity of the height-adjustable platform according to the invention is improved.

The connection elements can correspond to the engagement elements of an extension element, but this is not necessarily necessary. The shape of the base body of the connecting elements can be determined as desired. The base body can, for example, have a cover made of sheet metal. Advantageously, a gap can be covered in such a way that the platform surface remains barrier-free.

More preferably, at least one channel element can be provided, the channel element having a channel-like base body and at least two connecting elements that are complementary in arrangement and shape to the receiving elements of the base frame and to the receiving elements of the extension frame. The connecting elements are arranged on opposite sides of the base body in such a way that the base frame and/or extension frame can be connected to one another by engaging the connecting elements in the receiving elements.

The gutter-like base body of the gutter element can be used, for example, for line routing, cable routing and/or drainage of liquids, such as water. A gutter element can be particularly advantageously combined with a connecting element described above, the base body of which is designed in the form of a cover closing the gutter. If the gutter element is closed by a connecting element designed in this way, cables can be guided underneath the platform surface in a protected manner, without affecting accessibility. The gutter element can be provided with recesses in the base body, for example to be able to insert and remove cables.

In a preferred embodiment, at least one connection element is provided, the connection element having a tubular base body with a top, a bottom and two outer sides. The base body has a rectangular cross section perpendicular to the top, bottom and outside sides, with at least one connecting element that is complementary in arrangement and shape to the receiving elements of the base frame and/or the extension frame being provided on an outside of the base body. The top and/or the bottom of the base body has at least one recess for receiving add-on elements.

Similar to a connecting element or a gutter element, the connecting element can also have connecting elements arranged on both sides. Depending on the application, the connection element can be used to connect base elements and extension elements or can be fixed to the receiving elements of a base element or extension element by means of connection elements provided on one side.

The connection element thus represents a component for the modular expansion of a height-adjustable platform, by means of which a wide variety of add-on elements can be attached to the platform. The recesses in the top and/or the bottom of the connection element are preferably used for this purpose. Providing a connection element thus improves the versatility of the platform because the connection element can serve as a standardized interface for connecting a wide variety of components. This increases the number of identical parts used and reduces manufacturing costs.

In a preferred manner, at least one spindle base can be provided to support the platform against the ground. For this purpose, the top and bottom of the base body of the connection element each have at least one recess. The recess provided in the underside of the base body is arranged in alignment with the recess provided in the top side of the base body. The at least one spindle base penetrates the two recesses and is connected to the connecting element by means of a cooperating fastening element can be fixed to the platform.

Spindle feet can be used to bridge larger height differences between the ground and the platform if the height adjustability of the three-joint feet is not sufficient. Depending on the terrain and the required stability, several spindle feet can be provided per connection element, for example if the recesses are designed in the form of continuous grooves and the spindle feet arranged in the grooves are locked by union nuts or spindle foot clamps. This design has the additional advantage that the spindle feet can be moved in the grooves when the fasteners are loosened, for example when the support of the platform is to be changed or when the platform is to be relocated.

According to a preferred embodiment, at least one add-on element protruding beyond the base element surface is provided on the side of the platform facing away from the ground. The add-on element can be attached to the platform using the connecting element. The add-on element is preferably a railing, a sign, a post of a shelter or a leg of a seat.

The add-on elements allow the platform according to the invention to be adapted to the requirements, in particular the legal requirements. For example, required markings or security elements can be provided.

At least one post clamp is preferably provided which has a spur. The spur can be inserted into the recess of the connecting element and is designed to be fixable in its position in the recess of the connecting element by means of a fastening means. The spur is designed to protrude beyond the base element surface on the side of the platform facing away from the ground and the post clamp is designed to be fixable to the connecting element.

A spur enables the attachment of a variety of add-on elements, especially posts. The position of the spur can be adjusted subsequently, for example if the fixation in the recess is loosened again. The spur can thus be moved several times in the recess during the assembly process and serve as a receptacle for various add-on elements, for example to increase the safety of the platform by providing a railing attached to the spur.

In a preferred embodiment, at least one frame clamp is provided, the frame clamp being designed such that a rigid connection can be formed between the connection element and at least one base frame and/or an extension frame. If several base frames and/or extension frames are connected by the connection element to form a height-adjustable arrangement, the idea of the invention also includes using the frame clamp to form a rigid connection between the two frames and the connection element arranged between them. This advantageously improves the stability of a height-adjustable arrangement.

In a further preferred embodiment, at least one end element is provided, wherein the end element has at least one connecting element that is complementary in arrangement and shape to the receiving elements of the base frame and/or to the receiving elements of the extension frame. The end element can be fixed to a base frame or to an extension frame by engaging the at least one connecting element in a receiving element. The end element has a skirting board, the skirting board being designed in such a way that when the height-adjustable arrangement is used properly, it covers the space between the base frame or the extension frame and the subsurface. The skirting board can thus be attached to any outside sides of base frame struts or extension frame struts using the connecting elements and in this embodiment functions as a cover or apron. The end element therefore serves both as a visual privacy screen and as a demarcation for the space under the platform. This increases safety when using a height-adjustable arrangement and feet or objects getting caught in the space formed by the platform relative to the ground can be easily avoided.

Preferably, at least one traverse element is provided, wherein the traverse element is designed to be arranged along a base frame longitudinal strut, base frame cross strut, extension frame longitudinal strut or extension frame cross strut that delimits the height-adjustable platform. The traverse element is preferably designed to guide cables or to drain rainwater. The traverse element is preferably by means of a frame clamp or by means of a post clamp or with designed to be fixable to a base element and/or to an extension element by means of a spindle clamp.

In principle, a truss element can be fixed to a height-adjustable platform using any of the previously presented clamps. Other types of fastening, such as rivets, screws, welding, gluing or similar types of fastening, can also be used to fix a truss element to a platform according to the invention. The use of the clamps already presented leads to an increased number of identical parts and can therefore reduce production costs. Regardless of the type of attachment, the truss elements enable safe cable routing and/or water drainage, as well as improved accessibility to the laid cables, as they do not run under the platform.

In a preferred embodiment, at least one height-adjustable support frame is provided, which is designed to be connectable to the height-adjustable arrangement. The height-adjustable support frame has height-adjustable feet.

The at least one support frame can serve to provide additional support for the height-adjustable arrangement. It can be used, for example, if the requirements for the stability of the height-adjustable arrangement are particularly high or if particularly large height differences between the platform and the ground have to be bridged for which neither the three-joint feet nor the spindle feet are suitable. This situation can occur, for example, if a road ditch has to be bridged by a height-adjustable platform or a height-adjustable arrangement.

Additional support frames thus enable greater flexibility when using the height-adjustable platforms and arrangements and provide an advantageous option for compensating for large differences in height of the subsurface.

Further developments, advantages and possible applications of the invention also emerge from the following description of exemplary embodiments and from the figures. All described and/or illustrated features, individually or in any combination, are fundamentally the subject of the invention, regardless of their summary in the claims or their relationship.

Ways of carrying out the invention

The 1 shows a schematic representation of a base element 10 for forming a height-adjustable platform 1. The base element 10 has a base frame 12. In the in 1 In the schematic representation shown, the base insert plate 13 belonging to the base element 10 has been omitted for reasons of clarity. The base frame 12 is rectangular in shape in the embodiment shown and has a first base frame longitudinal strut 14, a first base frame cross strut 16, a second base frame opposite the first base frame longitudinal strut 14 men's longitudinal strut 18, and a second base frame cross strut 20 opposite the first base frame cross strut 16. The base frame longitudinal struts 14, 18 and the base frame cross struts 16, 20 are firmly connected to one another and enclose a base element interior 22, which they separate from a base element exterior 24. A base frame longitudinal strut 14, 18 and a base frame cross strut 16, 20 are arranged at a 90 ° angle to one another and thus form a corner 26 of the base frame 12. A height-adjustable foot 28 for supporting the base frame 12 against a surface 3 is arranged in each of the corners 26 of the base frame 12. In the embodiment shown, two height-adjustable feet 28 are welded to the longitudinal struts 14, 18. Of course, the height-adjustable feet 28 can also be fixed differently to the base frame 12. The only important thing for the function of the platform 1 is that the feet 28 are attached to at least one base frame longitudinal strut 14, 18 and/or to a base frame cross strut 16, 20, so that they can support the base frame 12 against a base 3.

Each of the base frame longitudinal struts 14, 18 and each of the base frame cross struts 16, 20 has at least one receiving element 34 in the form of an eyelet on an outer surface 30 facing the base element outer space 24. Both the first and second base frame longitudinal struts 14, 18 as well as the first and second base frame cross struts 16, 20 have on their respective inner surfaces 32 facing the base element interior 22 a support 36 for supporting the base insert plate 13 which can be arranged in the base element interior 22. In the exemplary embodiment shown, the base frame longitudinal struts 14, 18 and the base frame cross struts 16, 20 have an L-shaped cross section, so that one leg on the base frame 12 forms a circumferential support 36, which enables uniform support of the base insert plate 13, not shown.

Thus, the base insert plate 13 forms a common base element surface 11 facing away from the base 3 with an upper edge 21 of the base frame 12 that runs around the entire base frame 12 and faces away from the base 3. It goes from the 1 shows that no components of the base element 10 protrude upwards from the base element surface 11, which is why the height-adjustable platform 1 according to the invention is characterized above all by its excellent accessibility for people with limited mobility.

The 2 and 3 show exemplary embodiments for height-adjustable feet. All feet provided on the base element 10 or extension element 40 are preferably designed in such a way that their height can be changed individually in order to compensate for uneven terrain and thus ensure reliable support of the platform.

The in 2 The three-joint foot 70 shown has a first leg 71, a second leg 74, a first axle 77, a second axle 78, a third axle 79 and a setup element 82 intended for placement on the ground. Through the holding element 84, the three-joint base 70 can be connected to a base element 10 or an extension element 40, more precisely to a base frame 12 or an extension frame 42. The holding element 84 points upwards in the installed position, so that it defines the top of the three-joint base 70. This already shows that the three-joint base 70 is height-adjustable, but the height adjustment has no influence on the top of the holding element 84. A three-joint base 70 according to the invention is therefore ideal for use in barrier-free, height-adjustable platforms 1.

A first end 72 of the first leg 71 and a first end 75 of the second leg 74 are articulated to one another by means of the first axis 77. The axis 77 simultaneously represents a bearing for the setting up element 82. The axis 77 can be formed, for example, by a pin which is driven by the setting up element 82 and through the first ends 72, 75 of the first leg 71 and the second leg 74. A second end 73 of the first leg 71 facing away from the setting element 82 is connected to the holding element 84 in an articulated and fixed position with respect to the holding element 84 by means of the second axis 78. Consequently, the first leg 71 can only rotate about the second axis 78; a lateral displacement of the second end 73 is prevented by the inclusion of the second axis 78 in the holding element 84.

A second end 76 of the second leg 74 facing away from the setting element 82 is connected to the holding element 84 in an articulated and position-variable manner with respect to the holding element 84 by means of the third axis 79. The third axis 79 is therefore not permanently in engagement with the holding element 84. Rather, the second end 76 of the second leg 74 can be moved more or less freely if the third axis 79 is not fixed in the holding element 84. The mobility of the second leg 74 is then only limited by the connection to the first leg 71. The closer the second end 76 of the second leg 74 is moved towards the second end 73 of the first leg 71, the further away the setup becomes element 82 from the holding element 84. The distance between these two components consequently defines the height of the three-joint base 70. Once the appropriate height has been found, the second end 76 of the second leg 74 is rotatably locked on the holding element by means of the third axis 79, whereby the height adjustment of the Three-joint base 70 is fixed.

3 shows an alternative embodiment of a three-joint foot 90. The three-joint foot 90 has a first leg 91, a second leg 94, a first axis 97, a second axis 98, a third axis 99, a fourth axis 100, a fifth axis 101, a first one Set-up element 102 provided for setting up on the surface 3 and a second setting-up element 103 provided for setting up on the surface 3. In contrast to the previously described exemplary embodiment, the three-joint base 90 has two setting-up elements 102, 103, each of which can be rotated independently of one another on a leg 91, 94 are attached. The fourth axis 100 and the fifth axis 101 are intended for this.

Similar to the previous embodiment, a holding element 104 is provided for connecting the three-joint base 90 to a base element 10 or an extension element 40.

The functional principle of the three-joint base 90 is the same as before in relation to the in 2 shown foot 70 described functional principle. The first leg 91 and the second leg 94 are connected to one another in an articulated manner by means of the first axis 97. A second end 93 of the first leg 91, facing away from the first setting element 102, is connected to the holding element 104 in an articulated and fixed position with respect to the holding element 104 by means of the second axis 98. The second axis thus represents a reference point of the kinematic system formed by the two legs 91, 94. A second end 96 of the second leg 94, facing away from the second setting element 103, is articulated to the holding element 104 by means of the third axis 99 and is positionally variable with respect to the holding element 104 tied together. In the case of the three-joint foot 90, the height is accordingly determined by a displacement of the second end 96 of the second leg 94 towards or away from the second end 93 of the first leg 91. The position of the first axis 97 has a significant influence on the extent to which a sideways movement of the second end 96 of the second leg 94 is reflected in a change in height.

From the 2 and 3 It can also be seen that the holding element 84, 104 is formed by a substantially U-shaped profile with a web 85, 105 and two flanges 86, 106 which are connected to one another by the web 85, 105 and project essentially at right angles to the web 85, 105 becomes. As previously mentioned, the holding element 84, 104 is fastened in a corner 26, 56 of the base frame 12 or the extension frame 42 in such a way that the flanges 86, 106 are oriented in the direction of the mounting element 82, 102, 103, i.e. in the direction of Underground 3 points.

A first flange 86, 106 of the holding element 84, 104 is designed as a perforated rail 86, 106 with a plurality of holes 88, 108 arranged in a row. The row of holes 88, 108 runs parallel to the strut 14, 16, 18, 20, 44, 46, 48, 50 to which the holding element 84, 104 is attached. A second flange 87 of the holding element 84, 104 is designed as a wave rail 87 which has wave troughs 89 and wave crests. Here, the wave troughs 89 of the wave rail 87 are arranged in alignment with the holes 88, 108 of the hole rail 86, 106, so that they enable the third axis 79, 99 to be locked. The haptic feedback that the shaft rail 87 provides makes it intuitively clear to a fitter on the platform 1 where the holes 88, 108 of the hole rail 86, 106 are located if he wants to fix the position of the third axis 79, 99.

The 4 and 5 represent a base element 10 when viewed from above ( 4 ) and an extension element 40 ( 5 ) for forming a modular, height-adjustable platform 1. The differences between the base elements 10 and the extension elements 40 become particularly clear from the illustrations. While the base elements 10 have receiving elements 34 on each longitudinal strut 14, 18 and on each cross strut 16, 20, this only applies to extension elements 40 on three of their outer surfaces 60. The extension elements 40 namely have engagement elements 65 on an outer surface 60, which can be brought into engagement with the receiving elements 34, 64 of base elements 10 or extension elements 40 in order to form height-adjustable platforms 1. Because the engagement elements 65 preferably engage the receiving elements 34, 64 from above, the load acting on the platform 1 is transmitted to the receiving elements 34, 64 via the engagement elements 65. Thus, the extension elements on the strut on which the engagement elements 65 are arranged do not have any height-adjustable feet 58. This not only reduces the assembly effort when setting up the platforms 1, but is also suitable for reducing manufacturing costs due to the lower material requirement. In addition, the own weight of the extension element 40 is reduced, which is transmitted via the engagement elements 65 to the receiving elements 34, 64 and therefore to the neighboring one Base element 10 or the adjacent extension element 40 loads. The reduction in the weight of the extension element 40 results in a more stable position of the neighboring element and a systematic inertia, for example against impact loads.

The 6 until 13 show further elements that are used to form height-adjustable arrangements 200.

In 6 a connection element 230 is shown in an isometric view. The connection element 230 has a tubular base body 232 with a top 235, a bottom 236 and two outer sides, the cross section of the base body 232 having the shape of a rectangle. On an outside of the base body, connecting elements 234 complementary to the receiving elements 34, 64 of the base frame 12 and/or the extension frame 42 are provided. These can be brought into engagement with the receiving elements 34, 64 in order to attach the connection elements 230 to the base frame 12 and/or the extension frame 42. If the connecting elements 234 are provided on both sides of the base body 232, the base frame 12 and/or the extension frame 42 can also be connected by the connecting elements 230. The top 235 and/or the bottom 236 of the base body 232 has at least one recess 237 for receiving add-on elements 238, which can be used in a variety of ways, as can be derived from the following exemplary embodiments.

7 represents a frame clamp 250. The frame clamp 250 is designed such that a rigid connection between the connection element 230 and at least one base frame 12 and/or an extension frame 42 can be formed. For this purpose, the frame clamp 250 has a lower plate 254 with a hole and an upper plate 252 with a set screw on it. The upper plate 252 is designed such that when the set screw protrudes through the hole in the lower plate 254, it engages both a connection element 230 and the adjacent frame 12, 42. The lower plate 254 surrounds the frame 12, 42 and presses against the connecting element 230 from below. If the threaded pin is now guided from above through recesses 237 in the connecting element and if it protrudes further through the hole in the lower plate 254, the assembly can be opened The fastening element 256 attached to the set screw can be clamped. In the 7 A traverse element 270 is also shown in dashed lines, which is also braced by the frame clamp with the connecting element 230 and a frame 12, 42. The truss member 270 represents and replaces an extended lower plate 254. The traverse element 270 can be used to guide cables or drain water.

8th represents a post clamp 240. This works according to a similar principle as a frame clamp 250. The post clamp 240 has a spur 242, the spur 242 being designed to be insertable into the recess 237 of the connecting element 230. The spur 242 can be fixed in its position in the recess 237 of the connecting element 230 by means of a fastening means 244, the spur 242 protruding above the platform surface 5 on the side of the platform 1 facing away from the subsurface 3. The post clamp 240 is thus fixed to the connection element 230.

9 visualizes the use of a connection element 230 for receiving a spindle base 231, which is why the illustrated embodiment can also be referred to as a spindle base clamp. A spindle foot 231 can be used to bridge height differences that cannot be bridged by the three-joint feet 70, 90. In the illustrated embodiment, the top 235 and the bottom 236 of the base body 232 of the connecting element 230 are each provided with at least one recess 237. A groove extending almost over the entire top 235 and almost the entire underside 236 is preferably provided. The recess provided in the underside 236 of the base body 232 is arranged in alignment with the recess 237 provided in the upper side 235 of the base body 232. The at least one spindle foot 231 - several spindle feet 231 can also be accommodated by a single connection element 230 - penetrates the two recesses 237 and is fixed to the platform 1 by means of a fastening element 239 that interacts with the connection element 230. For example, the ones in the are suitable for this 9 shown union nuts, one of which is provided on the top 235 and one on the bottom 236 of the connecting element 230 in order to prevent movement of the spindle base both upwards and downwards. The spindle feet 231 protrude beyond the platform surface 5, but not laterally beyond the outer edges of the base frame 12 or the extension frame 42. The spindle feet 231 can be used, for example, when bridging larger height differences at the back of the platform (e.g. on road ditches) or when producing bridge-like structures Can be used with railings on both sides.

In the 10 a connecting element 210 is shown, as is the case, for example, for bridging gaps between the platforms 1 can be seen. The connecting element 210 has a base body 212 shaped as a cover, which can be made of sheet metal or plastic, for example. Two connecting elements 214 that are complementary in arrangement and shape to the receiving elements 34 of the base frame 12 and to the receiving elements 64 of the extension frame 42 are arranged on opposite sides of the base body 212. By engaging the connecting elements 214 in the receiving elements 34, 64, base frames 12 and/or extension frames 42 can accordingly be connected to one another.

The 11 shows a gutter element 220 with a gutter-like base body 222. The gutter element 220 also has two connecting elements 224 on each side that are complementary in arrangement and shape to the receiving elements 34 of the base frame 12 and to the receiving elements 64 of the extension frame 42. A cover element similar to a connecting element 210 can be placed on the gutter element 220. The cover element differs from the connecting element 210 only in a smaller distance between the connecting elements 214. The covering element can be inserted into receiving elements of the channel element 220 that are complementary to its connecting elements and thus covers the base body 222 of the channel element 220. In this way, a capped shaft can be formed between adjacent platforms 1.

A termination element 260, as shown in 12 is shown, can be provided to cover a height-adjustable arrangement 200 and thus give it a visually appealing appearance. However, it can also serve to increase security. The end element 260 has two connecting elements 264 that are complementary in arrangement and shape to the receiving elements 34 of the base frame 12 and/or to the receiving elements 64 of the extension frame 42, so that it can be attached in receiving elements of any base elements 10 or extension elements 40. The end element 260 has a skirting board 262 that covers the space between the base frame 12 or the extension frame 42 and the subsurface 3. This can prevent objects or living beings from getting under the height-adjustable platform, which could lead to a safety risk. The risk of a user falling can also be reduced and impacts from vehicles can be absorbed. Finally, the end element 260 serves as a privacy screen.

13 shows a schematic representation of a side view of a support frame 280 with height-adjustable feet 282. To accommodate the height-adjustable feet 282, the support frame 280 has vertical rods 284, which are connected to a frame by horizontal rods 286. The vertical rods 284 are preferably designed as tubes in which the height-adjustable feet 282, in particular spindle feet with a long spindle, are guided and can be locked. For this purpose, an adjustable stop for the spindle feet can be provided, for example at an end of the vertical rods 284 facing away from the ground 3, so that the weight of the support frames 280 and thus the platform 1 held by them is transferred to the spindle feet via the stop. The height-adjustable feet 282 have a ball joint at their end facing the surface 3, so that a support element 288 attached to this end of the feet 282 can compensate for unevenness in the surface 3.

Different options are available for attaching the support frames 280 to a height-adjustable arrangement 200. For example, the support frames 280 can have a mandrel on the top of the vertical rods 284, which can protrude through the recesses 237 of connecting elements 230 and can be fixed to the connecting element 230 by means of a fastening element 239. Alternatively or additionally, the support frames 280 can have connecting elements, for example in the form of engagement elements or receiving elements, which can be connected directly to receiving elements 34, 64 of a base element 10 or an extension element 40. An indirect connection of the support frames 280 to base elements 10 or extension elements 40, for example through connecting elements 210, gutter elements 220 or frame clamps 250, is also possible.

Several support frames 280 can also be connected by mounting frames arranged perpendicular to the support frames 280 to form cuboid structures that can be expanded as desired. The mounting frames can, for example, be hung in designated receptacles in the support frames 280. The support frames 280 can be braced diagonally to increase the stability of the structure.

The support frames 280 can therefore also be used to bridge large height differences between a height-adjustable arrangement 200 and a base 3, with the stability of a platform 1 according to the invention or a height-adjustable arrangement 200 being maintained or even improved.

14 shows a schematic representation of an isometric view of a height-adjustable platform 1 and a height-adjustable arrangement 200 constructed therefrom. The platform 1 has a base element 10 and two extension elements 40, which are connected to one another by receiving elements 34, 64 and engagement elements 65. The base element 10 has a base insert plate 13, which is covered by a base cover plate 15 in the view shown. The base cover plate 15 has a special tactile surface texture that is suitable for making orientation easier for people with limited vision through tactile elements. In a similar manner, one of the extension elements 40 also has an extension insert plate 43, which is, however, covered by an insert cover plate 45 in the figure. The extension cover plate 45 has a surface texture that is different from the base cover plate 15. In the exemplary embodiment shown, a non-slip rubber surface ensures that people can stand safely on the platform 1 without slipping. Within the scope of the invention, the modular structure of the platform 1 makes it possible to combine different surface textures in a platform 1

The base element surface 11 and the extension element surface 41 form a common platform surface 5 from which no objects protrude and which is not interrupted by gaps. People can therefore move barrier-free on platform 1. In order to enable barrier-free access to the platform 1, a ramp can be hung into the receiving elements 34 provided on the base element 10, via which people can access the platform surface 5 without any steps.

The second extension element 40 is shown without an extension insert plate 43 and without an extension cover plate 45 in order to make the frame 42 and a height-adjustable foot 58 of the extension element 40 more visible. By adding further expansion elements 40, the platform 1 could be further enlarged. Likewise, the platform 1 could be expanded into a tile-like, flat, height-adjustable arrangement 200 by adding base elements 10 or extension elements 40 perpendicular to the direction in which the base elements 10 and extension elements 40 are joined together. In other words: Several height-adjustable platforms 1 can be arranged next to one another and joined together to form a platform assembly, i.e. a height-adjustable arrangement 200.

In the present case, the front of the platform 1 is covered by end elements 260, which are attached to the platform 1 by connecting elements 234. The skirting boards 262 of the end elements 260 fill the space between the subsurface 3 and the platform 1. This prevents accidents and also prevents objects from getting into the space under platform 1.

Some add-on elements 238 are attached to the back of the platform 1 by means of connecting elements 230. The connection elements 230 are firmly connected to the platform 1 by means of frame clamps 250. A railing is fixed to the platform 1 by post clamps 240 that interact with the connecting elements 230 in order to provide people standing on the platform 1 with an opportunity to hold on and to avoid falls from the platform 1. Furthermore, a post with an attached display sign and trash can is fixed to platform 1. It is not difficult to see that the height-adjustable arrangement 200 in the application shown serves as a mobile stop, for example for buses or trams, which is a preferred application.

However, due to their versatility as well as their modular expandability and accessibility, the height-adjustable platform and a height-adjustable arrangement constructed from it can also be used for other purposes, for example in event technology.
