Supporting element construction for a balcony railing and its use

Description

[0001] The invention relates to a support element construction for a balcony railing in order to connect several support elements of the balcony railing to one another in order to erect the balcony railing, wherein the support element construction comprises a first support element, a second support element and a coupling piece in order to connect the first support element and the second support element to one another with the coupling piece.

[0002] Furthermore, the invention relates to a use of the supporting element construction.

[0003] To erect a balcony railing, various support element structures are known. These are generally formed from several support elements, often designed as structural profiles. The support elements are usually bolted, welded, or riveted together to erect the support element structure. Support elements often take the form of vertically aligned columns, horizontally aligned railing chords connecting columns, balusters connecting several railing chords, and / or handrails forming the upper boundary of the railing. Depending on the application, these various forms are connected to one another in different configurations and spacings to form a balcony railing.

[0004] When it comes to balcony railings, particular importance must be attached to the high level of stability and safety of the structure of the balcony railing or the supporting element construction of the balcony railing. This is why balcony railings must generally be erected by a specialist or professional. This ensures that the supporting elements of the balcony railing are connected to one another in a sustainable and robust manner. In particular, connecting elements such as screw connections, bolt connections, rivets and weld points which connect the supporting elements to one another are placed correctly and without errors. When connecting several supporting elements, the connecting elements should normally be placed or used in such a way that unwanted prestressing in the supporting element construction is avoided. This is to prevent stress peaks in the supporting element construction as far as possible during later use. Another important aspect to note is that screw connections andRivets should generally be positioned and designed in such a way that they do not pose an obstacle or risk of injury to a user during subsequent use. Given these requirements, a balcony railing, or rather its supporting element structure, and its installation, are, upon closer examination, associated with a high degree of complexity. Therefore, in practice, their installation is generally not feasible by a layperson if the high stability and safety of the supporting element structure is to be ensured in the long term.

[0005] This is where the invention comes in. The object of the invention is to provide a supporting element construction for a balcony railing of the type mentioned above, which offers high practicality and safe handling.

[0006] The document AU 477 021 B2 discloses a support element construction for a balcony railing in order to connect several support elements of the balcony railing to one another in order to erect the balcony railing, wherein the support element construction comprises a first support element, a second support element and a multi-part coupling arrangement.

[0007] The document US 2007 / 137134 A1 discloses a support element construction for a wall structure, wherein a plurality of support elements are connected to one another to erect the wall structure and wherein the support element construction comprises a first support element, a second support element and a coupling piece, wherein the coupling piece is inserted displaceably and positively into a receiving groove of the respective support element.

[0008] A further aim is to specify a use of a load-bearing element construction of the type mentioned above.

[0009] The object is achieved according to the invention by a supporting element construction according to claim 1.

[0010] The background to the invention is the idea of designing a supporting element construction for a balcony railing in such a way that the usual connecting means for connecting two supporting elements, such as screw and bolt connections, rivet connections or welded connections, which establish a relative position between the two supporting elements in a robust but practically almost impossible to move - once several welded or screw connections have been set, there is generally hardly any possibility of subsequently changing the relative position of two supporting elements established by them - can be largely dispensed with.If such fasteners are used, a high degree of advance planning with little tolerance for error is generally required, as these fasteners have to be correctly set and positioned right from the start of the construction of the load-bearing element structure. Subsequent changes to their position are only possible to a limited extent and the usually high rigidity of load-bearing elements means that subsequent compensation for previously created inaccurate fastener positioning and inaccurate relative positioning of the load-bearing elements to one another is usually hardly possible or only possible by applying force to the load-bearing elements or fasteners and the associated high mechanical stresses. By providing in the aforementioned manner that load-bearing elements or the first load-bearing element and second load-bearing element with orare connected by the coupling piece via a first guide system and a second guide system, so that a positive connection is implemented between the first support element and the coupling piece as well as between the second support element and the coupling piece, which allows a guided relative displaceability between the support elements and the coupling piece - hereinafter also referred to as the displacement state - the support elements can be connected in a positive fit and only then can a preferred relative end position between the support elements be determined, usually with a locking device provided for this purpose. Since relative displaceability is provided both between the first support element and the coupling piece and between the second support element and the coupling piece, the relative position of the support elements to one another can be flexibly changed or adjusted later.adjusted, which allows for a low-stress structure and efficiently avoids later stress peaks.

[0011] It is understood that guided displaceability usually means that displaceability in the form-fitting connected state can occur in directions predetermined by the respective guide system, but not, apart from a usual clearance fit, in at least one, often several or all directions or axes orthogonal to this. For ease of handling, it is usually provided that the form-fitting connection between the first or second support element and the coupling piece brought about by the first or second guide system is present in at least two mutually orthogonal directions, often all directions or axes, each of which is orthogonal to a displacement direction predetermined by the first guide system or second guide system, in which direction the respective support element is displaceable relative to the coupling piece.

[0012] In order to practically adjust a relative position between the first and second support elements, it is advantageous if the first support element can be positively connected to the coupling piece by the first guide system or the second support element by the second guide system in such a way that the first support element can be displaced in a guided manner relative to the coupling piece along a longitudinal axis of the first support element or the second support element can be displaced in a guided manner relative to the coupling piece along a longitudinal axis of the second support element. It is expedient in this case if guided displaceability is enabled at least along a distance which amounts to more than 10%, in particular more than 20%, preferably more than 30%, particularly preferably more than 40% of a longitudinal extent of the first support element or second support element.High flexibility can be achieved if guided displacement is provided at least along a distance that amounts to more than 75%, preferably more than 80%, of a longitudinal extension of the first or second support element. For particularly high flexibility, it is advantageous if guided displacement is provided along the entire longitudinal extension of the first or second support element.

[0013] It is practical if one or more deactivatable stop mechanisms are present which prevent a positive connection established with the first and / or second guide system between the first support element or second support element and the coupling piece from being released, and only allow this release when the stop elements are deactivated. In this way, an unintentional release of the positive connection established with the first or second guide system can be prevented. A stop mechanism for a positive connection, i.e. a connection through spatial inclusion which allows guided displaceability, is easily implemented in that the stop mechanism has a movable stop element which, in the deactivated state, cancels the positive connection and, in the activated state, restores it.For this purpose, the stop element can be designed, for example, as a flap or sliding element, which is preferably movable against an elastic force to release the positive locking in order to deactivate the stop element.

[0014] It is expedient if the first guide system and / or second guide system each has a locking device for positively and / or non-positively fixing a relative position between the first support element and the coupling piece or between the second support element and the coupling piece in different relative positions to one another, in particular by forming a press connection. This allows a respective relative position between the first or second support element and the coupling piece to be fixed or locked, preventing further guided displacement of the first or second support element relative to the coupling piece and, in particular, allowing a relative position between the first and second support elements to be fixed.For this purpose, it has proven useful if the locking device has one or more pressing elements which can be pressed against one or more pressing element counter-surfaces to create a press connection in order to fix the relative position. For high robustness, it is advantageous if the pressing elements are designed as screws, in particular as worm screws, which are arranged on the coupling piece and / or support element and can be pressed, in particular by screwing, onto a pressing element counter-surface arranged on the respective support element or coupling piece or formed thereby in order to create the press connection. Alternatively or cumulatively, it can be provided that the pressing elements are loaded with a spring force when they press against the pressing element counter-surface in order to create the press connection or to adjust a pressing force of the press connection. The press connection can preferably be released by moving the pressing elements against the spring force.

[0015] A high level of stability can be achieved if the first guide system and / or second guide system each have a first guide element which is part of the respective support element or is connected thereto, and a second guide element which is part of the coupling piece or is connected thereto, wherein one of the guide elements is formed with a guide receptacle and the other guide element is formed with a guide pin which corresponds in shape to the guide receptacle, which guide pin can be inserted at least partially into the guide receptacle for connecting the respective support element to the coupling piece to form a positive connection, so that the guide pin can be displaced in a guided manner in the guide receptacle, in particular along a longitudinal extent of the support element.Depending on the specific design, the first support element and second support element can each have the guide receptacle, and the coupling piece can have the corresponding guide pins, or vice versa. It is also possible for the first support element to have a guide receptacle and the second support element to have a guide pin, while the coupling piece can have a corresponding guide pin and a guide receptacle.

[0016] For high robustness and stability, it has proven effective if the first support element and the second support element each have the guide holder or are rigidly connected to it and the guide pin corresponding to the guide holder is formed as part of the coupling piece or is rigidly connected to it.

[0017] A low susceptibility to errors can be achieved if the guide receptacle is designed with a channel or a groove, so that the guide pin corresponding to the guide receptacle can be moved along the channel or the groove when inserted into the guide receptacle.

[0018] The "guide pin" refers in particular to that part of the coupling piece which, in order to assume the sliding state, can be inserted at least partially, in particular entirely, into the respective guide receptacle in a form-fitting manner. In particular, the part of the guide pin which can be inserted entirely into the guide receptacle is referred to as the "guide pin segment."

[0019] Typically, the first or second guide system is configured such that, in a displacement state in which the guide pin is arranged in the guide receptacle in a guided, displaceable manner, the guide receptacle engages behind a guide pin segment of the guide pin inserted into the guide receptacle to establish a positive connection between the guide receptacle and the guide pin in a direction orthogonal to the displacement direction. This makes it practical to establish a positive connection in a further direction orthogonal to the displacement direction, generally counter to a depth direction of the guide receptacle, and in particular, to prevent the guide pin from sliding out of the guide receptacle.For this purpose, it is expedient if the guide pin has a varying outer diameter, particularly along a longitudinal extent of the guide pin, in order to establish a positive connection between the guide pin and the guide receptacle. A robust connection can be implemented if the guide receptacle has one or more limiting elements in order to engage behind the guide pin segment with the limiting elements. The guide pin can have one or more limiting element receptacles that correspond in shape to the limiting elements and into which the limiting elements can be inserted to establish the positive connection between the guide receptacle and the guide pin or to engage behind the guide pin segment. The guide pin can be inserted into the guide receptacle via an insertion opening arranged on the support element or on the guide receptacle.The insertion opening can be formed, for example, by the guide receptacle being designed as a laterally open profile or by the limiting elements being interrupted at a section of the guide receptacle so that the guide pin can be inserted into the guide receptacle. The guide pin preferably has at least two limiting element receptacles arranged on opposite sides of the guide pin, into which limiting elements of corresponding shape can be inserted. If the guide receptacle is designed with a channel or a groove, it is advantageous if, in a cross-section orthogonal to the longitudinal direction of the channel or the groove, one or more limiting elements are arranged on a wall with which the channel or the groove is formed, protruding from the wall in order to engage behind the guide pin segment, in particular by inserting the limiting elements into corresponding limiting element receptacles on the guide pin.

[0020] Alternatively, it may be advantageous if no engagement of the respective guide pin segment with the respective guide receptacle is provided, especially since engagement, for example with the aforementioned limiting elements, requires additional design effort and makes inserting or releasing the guide pin into or from the guide receptacle more difficult. Slipping out or unintentional release of the guide pin against a direction of insertion of the guide pin into the guide receptacle, which is usually oriented orthogonally to the direction of displacement, is prevented by blocking movement of the coupling piece against this direction of insertion in the other support element, for example by a positive or non-positive fixing or locking of the coupling piece in the other support element, with the blocking device described below.

[0021] According to the invention, in a direction orthogonal to the direction of displacement, in particular counter to the direction of insertion into the guide receptacle, there is no positive connection between the coupling piece or its guide pin and the first or second support element, so that the coupling piece can be released from the respective support element by moving the coupling piece orthogonal to the direction of displacement. In particular, this advantageously allows the positive connection or the connection between the coupling piece and the respective support element to be connected or released without relative displacement of the latter in the direction of displacement. Accordingly, it is advantageous if the guide receptacle is designed in this way. It is expedient if this is the case for at least 30%, in particular at least 50%, preferably at least 75%, particularly preferably at least 90%, of a displacement path along which guided displacement between the coupling piece and the respective support element is possible.Particularly preferably, this applies essentially to the entire displacement path. In the case of a guide receptacle, the displacement path is usually determined by the longitudinal extent of the guide receptacle. This enables quick and practical insertion and removal of the coupling piece from the respective support element. This enables easy connection and removal of the support elements to and from one another. This has proven particularly useful when, in the displacement state, a displacement direction of the first support element relative to the coupling piece predetermined by the first guide system is angular, in particular orthogonal, to a displacement direction of the second support element relative to the coupling piece predetermined by the second guide system.For example, if the longitudinal axes of the support elements are aligned at an angle, in particular orthogonally, to one another in the displaced state and a respective guided displaceability along the respective longitudinal axis is provided. Such a connection or coupling between the support element and the coupling piece without a positive connection in a direction orthogonal to the displacement direction, in particular counter to the insertion direction into the guide receptacle, can be achieved, for example, in that the guide receptacle does not have any of the aforementioned limiting elements in order to engage behind the guide pin segment of the coupling piece. Alternatively, however, it can also be provided that the guide receptacle has such limiting elements, but the coupling piece is designed in such a way that when the coupling piece is inserted into the guide receptacle or in the displaced state, the guide pin or the guide pin segment of the coupling piece is not engaged behind by the limiting elements.For example, the guide pin segment, when displaced, has a width that is smaller than the spacing of the limiting elements from one another, so that the guide pin segment can be guided between the limiting elements. Depending on the design of the coupling element or its guide pin, a flexible connection type can be selected in this way.For example, if a plurality of second support elements are connected to the first support element in the manner described in this document, in that a coupling piece is each inserted into the same guide receptacle of the first support element in a form-fitting manner, in particular in the displaced state, for example depending on the design of the coupling piece, at least one of the coupling pieces can be connected to the first support element by engaging behind its guide pin segment with limiting elements of the guide receptacle of the first support element and at least one of the coupling pieces can be connected to the first support element without engaging behind its guide pin segment with the limiting elements.

[0022] It has proven useful according to the invention for the first guide system and second guide system each to have a deactivatable blocking device in order to block a guided displacement of the coupling piece relative to the respective support element in at least one of the displacement directions and to allow this when the blocking device is deactivated. In particular, if there is no positive connection between the coupling piece and the first or second support element in a direction, for example a first direction, orthogonal to the displacement direction, the coupling piece can be prevented from sliding out or detaching from one of the support elements by preventing a guided displacement of the coupling piece relative to the other support element with the blocking device in this, in particular first, direction. This can also be implemented with the aforementioned locking device.The blocking device can, for example, be formed with a stop element that forms a stop against displacement of the coupling piece in one of the displacement directions. For example, the stop element can form a stop against displacement of the guide pin in the guide receptacle in one or more of the displacement directions. It is expedient if the stop element is a component that can be inserted into the guide receptacle, in particular detachably. For a robust connection, the stop element can be inserted into the guide receptacle, creating a force-locking and / or form-locking connection between the stop element and the guide receptacle. The stop element can be inserted at least partially or completely countersunk into the guide receptacle.It is practical if the blocking element is designed according to the features of the cover element described below, in particular if it can be connected to the guide receptacles in a corresponding manner. It is advantageous if the stop element has a stop element closure in order to arrange the stop element in a form-fitting and / or force-fitting manner, in particular releasably, on the guide receptacle or the support element. The stop element closure can, in particular, be designed according to the cover element closure described below. High practicality can be achieved if the blocking device is designed as part of the aforementioned locking device.

[0023] For high stability and practicality, it is advantageous if the guide pin or the guide pin segment, in a displacement state in which the guide pin segment is connected to the guide receptacle in a guided and displaceable manner, has a greater length in a displacement direction predetermined by the guide receptacle than in a direction orthogonal to the displacement direction. In this way, unintentional tilting of the guide pin segment in the displacement state, in particular during displacement of the guide pin relative to the guide receptacle, can be prevented or inhibited. It is expedient here if a length of the guide pin segment in the displacement direction is at least twice, in particular at least three times, preferably at least four times, particularly preferably at least five times, as long as a length of the guide pin segment in a direction orthogonal to the displacement direction.Excellent handling is particularly achieved when the length of the guide pin segment in the direction of displacement is a maximum of ten times, in particular a maximum of seven times, preferably a maximum of six times, as long as the length of the guide pin segment orthogonal to the direction of displacement. Alternatively or cumulatively, it is advantageous for high stability and practicality if the guide pin segment, in the displacement state, has a cross-section orthogonal to a displacement direction predetermined by the guide receptacle or the longitudinal axis of the guide receptacle, which width is at least twice, in particular at least three times, preferably at least four times as large as a height of the guide pin segment orthogonal to the width. Excellent handling is particularly achieved when the width is a maximum of ten times, preferably a maximum of six times, as large as the height. The aforementioned designs apply analogously and advantageously to the guide pin.

[0024] The "displacement state" refers, in particular, to a state in which the guide pin or the guide pin segment is positively connected to the guide receptacle in such a way that the guide pin can be displaced relative to the guide receptacle while guided by the guide receptacle. The "guiding direction" refers, in particular, to a direction in which, in the displacement state, the guide pin can be displaced relative to the guide receptacle in a predetermined manner by the guide receptacle.

[0025] It is practical if the guide pin segment, in a displacement state in which the guide pin segment is connected to the guide receptacle in a guided, displaceable manner, has a polygonal outer contour, preferably an outer contour in the shape of a triangle, quadrilateral, in particular a rectangle, square, or trapezoid, in a cross-section orthogonal to the displacement direction specified by the displacement receptacle. This allows for error-free displacement and uncomplicated operation. It is understood that the outer contour can also be more angular, but the aforementioned designs have proven particularly easy to operate. The aforementioned designs apply analogously and advantageously to the guide pin.

[0026] Easy alignment of the support elements relative to one another by displacement is achievable if a contact surface, against which the guide pin segment rests on the guide receptacle in the displacement state, is designed as a plane. It is preferred if the contact surface or plane is designed substantially parallel to the displacement direction. In this way, easy displacement of the guide pin segment in the guide receptacle is achievable, while at the same time sufficient contact surface friction can be implemented so that any unintentional slipping of the guide pin segment in the guide receptacle is significantly inhibited. Such a contact surface can be formed, for example, with an aforementioned limiting element that engages behind the guide pin segment.This can be implemented particularly efficiently by forming the contact surface with a flat outer surface of the guide pin segment and with a flat outer surface of the guide receptacle.

[0027] An aforementioned locking device can be implemented in a practical manner if the guide pin or its guide pin segment has one or more aforementioned pressing elements, in particular in the form of screws, preferably worm screws, which can be pressed against one or more pressing element counter-surfaces arranged on the guide receptacle in order to produce a press connection, in particular by screwing in, in order to lock the guide pin in the guide receptacle or relative to it. It is expedient if the pressing element counter-surfaces are formed with the guide receptacle or are arranged on it. For this purpose, the pressing elements can be arranged in drilled holes in the guide pin or the guide pin segment or can be screwed into them in order to produce the press connection by passing or screwing the pressing elements through the drilled holes.

[0028] It is advantageous if the coupling piece or the two second guide elements are designed such that, in a displacement state in which the first support element is connected to the coupling piece in a guided and displaceable manner by the first guide system and the second support element is connected to the coupling piece in a guided and displaceable manner by the second guide system, a displacement direction of the first support element relative to the coupling piece predetermined by the first guide system is angular, in particular orthogonal, to a displacement direction of the second support element relative to the coupling piece predetermined by the second guide system. In this way, the first support element and second support element can be arranged or connected to one another at an angle, in particular orthogonal, to one another in a particularly easy-to-handle manner, in particular with high practicality if the aforementioned displacement directions are parallel to a longitudinal axis of the respective support element.

[0029] A robust implementation can be achieved if the coupling piece is formed with two legs, in particular legs that are connected to one another at an angle, wherein one of the second guide elements is arranged on one of the legs or one of the legs each has one of the second guide elements. This is particularly true if the two second guide elements of the coupling piece are designed as guide pins. It is practical if the longitudinal axes of the legs define a leg angle in order to connect the first support element and the second support element with a support element angle between the support elements that corresponds to the leg angle, in particular between their longitudinal axes. Since the leg angle can be used to influence the support element angle, a coupling piece with a corresponding leg angle can be selected between the first and second support elements, depending on the desired support element angle.This makes it particularly easy to adjust the desired relative alignment of the support elements. Depending on the application conditions, different leg angles from 0° to 180° between the legs or their longitudinal axes are suitable. Leg angles of 90°, 45°, 30°, 120°, and 135° are particularly practical and enable a support element design with particularly high stability. A leg angle of 0° or 180° corresponds to a coupling piece formed with a single leg, shown below, for example, in . Fig. 8 .

[0030] It is advantageous if the coupling piece is essentially rod-shaped, with one of the second guide elements being formed by a longitudinal side of the coupling piece and the other second guide element being formed by a broad side of the coupling piece. This allows for high robustness under directional loading in an operational state. This has proven particularly effective with an angular, especially orthogonal, alignment of the support elements or their guide directions.

[0031] For example, the coupling piece can be designed as a coupling piece rod, with a long side of the coupling piece rod forming one of the second guide elements and an end piece or a wide side of the rod forming the other second guide element. The second guide elements are preferably designed as guide pins. The coupling piece rod can be designed, for example, in the form of a board or a strip.

[0032] A high level of flexibility can be achieved if the coupling piece has a joint, in particular a hinge, which connects the two second guide elements so that they can be pivoted relative to one another in order to connect the first support element and the second support element so that they can be pivoted relative to one another. In this way, the support elements can be pivoted as required in order to adjust a desired relative position or pivoting between the support elements. It is advantageous if a fixing mechanism is present in order to define or fix a pivoting position set with the joint in a form-fitting and / or force-fitting manner. For ease of use, it is advantageous if the fixing mechanism is designed as part of the joint. It has proven useful if the joint is arranged between the aforementioned legs so that the legs can be pivoted relative to one another.The joint can define one or more axes of rotation around which the two legs can pivot relative to each other. It is practical if one axis of rotation of the joint, around which the two legs can pivot relative to each other, is aligned orthogonally to the longitudinal axes of both legs. Alternatively or cumulatively, the axis of rotation can be aligned orthogonally to one leg and parallel to the other leg. For high flexibility, the joint can be designed as a ball joint.

[0033] For exceptional robustness, it is advantageous if the guide receptacle is arranged at least partially, preferably entirely, in a particularly groove-shaped recess in the support element or is formed with such a recess. In this way, the guide system can be designed to be particularly robust and, moreover, protected from environmental influences and contamination. In particular, the aforementioned groove or channel of the guide receptacle can be formed with the recess. Preferably, the recess or its longitudinal axis extends along a longitudinal extent of the guide receptacle or the support element.

[0034] It has proven particularly useful if the support element has a further guide receptacle which is arranged in the recess or formed therewith, i.e. the support element has several, preferably two, guide receptacles which are arranged in the recess or formed therewith. This allows a high level of flexibility and a wide variety of uses. For example, different coupling pieces for connecting the support element, in particular in the manner described above, to several further support elements, for example the first support element to several further second support elements or vice versa, can be inserted into the guide receptacles in a manner distributed over the latter. It can be expedient if the guide receptacles define displacement paths running parallel to one another, along which coupling pieces inserted into them can be guided and displaced. Advantageously, several further guide receptacles can be arranged in the recess or formed therewith.

[0035] The guide receptacles arranged in the recess or formed with it can be designed according to a variant of embodiment described in this document, in particular above. For example, as explained in particular above, each with a channel or a groove. For high usability, it is advantageous if the guide receptacles are designed differently in order to each accommodate a different type of coupling piece or to connect coupling pieces with a different type of connection, for example with or without engagement behind it. It has proven particularly useful if one of the guide receptacles is designed, as explained above, to engage behind a guide pin segment of a guide pin inserted into the guide receptacle in the displacement state in order to create a positive connection between the guide receptacle and the guide pin in a direction orthogonal to the displacement direction.For example, with the aforementioned limiting elements. And the at least one other guide receptacle, as explained above, is not designed for corresponding engagement behind a guide pin or is designed such that, in the displacement state in a direction orthogonal to the displacement direction, in particular counter to a depth direction of the recess, there is no positive connection between a coupling piece inserted into this guide receptacle or its guide pin and the guide receptacle, so that the coupling piece can be released from the support element by moving the coupling piece orthogonal to the displacement direction.

[0036] A compact design can be achieved if the guide receptacles are arranged one behind the other in the depth direction of the recess. It has proven particularly useful if a guide receptacle arranged downstream in the depth direction, as described, is designed to engage behind a guide pin segment of a guide pin inserted into it in the displacement state, for example with limiting elements, and a guide receptacle arranged upstream of this, as described, is not designed to engage behind a guide pin accordingly or is designed such that, in the displacement state in a direction orthogonal to the displacement direction, in particular counter to the depth direction of the recess, there is no positive connection between this and the coupling piece inserted into it.This can be implemented in a particularly practical way if the recess walls forming the recess have limiting elements, so that the limiting elements define a recess area downstream of the limiting elements in the depth direction for forming the downstream guide receptacle and a recess area upstream of the limiting elements in the depth direction for forming the upstream guide receptacle within the recess. The limiting elements can expediently form a form fit or stop in the depth direction of the recess for a guide pin segment that is inserted into the upstream guide receptacle in a form-fitting manner or in a displaced state, or the guide pin segment can bear against the limiting elements. In this way, different types of connection orDifferent coupling pieces can be used to create a positively movable connection with the supporting element. In particular, depending on the design, particularly the shape, of the coupling piece or its guide pin segment, the coupling piece can be inserted in a form-fitting, movable manner into the guide receptacle positioned upstream or downstream in the depth direction. This can be achieved, as described above, in the downstream guide receptacles with or without the limiting elements engaging behind the guide pin segment.

[0037] It is understood that the first and / or second support element can be designed in this way.

[0038] To ensure a high level of safety and robustness over the long term, it is advantageous to have at least one cover element that can be arranged on the support element in a form-fitting and / or force-fitting manner such that, in the depth direction of the recess, the cover element at least partially, in particular in sections, covers an opening cross-section of the recess or the guide receptacle arranged in the recess. The opening cross-section is usually arranged orthogonally to the depth direction. Preferably, several such cover elements are provided.In order to efficiently implement high levels of security and robustness, it is expedient if the cover element has a cover surface which, when arranged on the support element, conceals or covers at least 60%, preferably at least 75%, particularly preferably at least 90%, of a recess width orthogonal to the longitudinal direction of the recess when viewed in the depth direction. The cover element preferably conceals the recess width essentially entirely. The cover surface is preferably designed as a flat surface, for example in the form of a cover plate. The cover element can be arranged in front of an opening in the recess or can be arranged at least partially, particularly entirely, in the recess or can be inserted into the recess.It is practical if the cover element can be arranged on the support element in such a way that, in a recess cross-section orthogonal to the recess's longitudinal axis, an edge of the cover surface has the same height in the depth direction as an edge of the recess, in particular an edge of the cover surface merges essentially continuously into an edge of the recess. Preferably, the cover surface and an edge of the recess form a plane. This reduces the risk of injury during later use. With the aforementioned measures, the recess or the guide receptacle arranged therein can be protected from external weather influences. In particular, the cover elements limit unwanted accessibility for a later user to the guide systems, in particular to the guide receptacle and a guide pin connected to it or to the locking device.Furthermore, the cover element has an aesthetic effect, especially since it conceals the guide system, preferably visually, and thus a construction or connection mechanism of the support element construction is less visible to a later user, in particular hidden from him.

[0039] It is expedient if a cover element closure, in particular in the form of a quick-release fastener, is provided in order to arrange the cover element in a form-fitting and / or force-fitting manner, in particular detachably, on the support element. Easy handling can be achieved if the cover element closure is designed as a quick-release fastener. A quick-release fastener makes it possible to close or release a connection quickly and without tools. It is advantageous if the quick-release fastener is designed as a snap fastener. In this case, it is usually provided that a form-fitting and / or force-fitting connection, in particular between the cover element and the support element, can be produced by elastically deforming a snap element and then bringing about a form-fitting and / or force-fitting connection. As a rule, the form-fitting or force-fitting connection can be canceled again by further elastic deformation of the snap element.

[0040] Simple handling can be achieved and the cover element closure can be implemented in a simple manner if the cover element or the support element has one or more fastening pins and the support element or the cover element has one or more corresponding fastening pin receptacles in order to connect the cover element to the support element in a form-fitting and / or force-fitting manner, in particular in a releasable manner, by inserting the fastening pins into the fastening pin receptacles. In particular, the fastening pin can be designed with or as the aforementioned snap element. It is practical and promotes safety if, when arranged on the support element, the cover element closure, in particular the fastening pins or fastening pin receptacles, are covered by the cover surface in the depth direction of the recess. For this purpose, recess pins orRecess pin receptacles are arranged on a side of the cover surface facing the recess.

[0041] For a robust connection and aesthetically pleasing arrangement, it has proven effective if, when the cover element is arranged on the support element, the fastening pins or fastening pin receptacles are arranged in the recess or between the recess walls forming the recess. For this purpose, recess pins or recess pin receptacles arranged on the support element can be formed with recess walls or arranged on these. It has proven effective if the cover element has several recess pins and the support element or the recess walls have several corresponding recess pin receptacles. Recess pin receptacles are preferably arranged on opposite recess walls, usually upstream of the guide receptacle arranged in the recess in the depth direction of the recess.

[0042] It is advantageous if the cover element can be arranged in a form-fitting manner on the support element such that the cover element can be displaced relative to the support element along a longitudinal extent of the recess or a longitudinal extent of the guide receptacle. This allows the cover element to be easily displaced into a desired position after being arranged on the support element. It is practical for this purpose if the fastening pin receptacle is designed as a fastening groove into which the fastening pin can be inserted in a form-fitting manner, wherein the fastening groove extends along a longitudinal extent of the recess such that the fastening pin can be displaced along the fastening groove after the fastening pin has been inserted into the fastening groove in a form-fitting manner.

[0043] Typically, a plurality of cover elements can be arranged on the support element to cover the recess or the guide receptacle at least in sections.

[0044] For high practicality and functionality, it is expedient if the cover element has at least one holding device in order to fix a surface element, in particular a plate element, in a state in which the cover element is arranged on the support element, with the holding device in a form-fitting and / or force-fitting manner on the support element, usually arranged between a plurality of support elements. This makes it easy to fix or stretch a surface element, for example in the form of a screen or a passage barrier, also referred to as a field filling in the case of railings, between a plurality of support elements. Typically, it is provided that a plurality of cover elements, having holding devices, are arranged on one or more support elements, in particular the first and / or second support element, in order to fix the surface element with the holding devices of the cover elements.It can be practical if a cover element has several retaining devices. A robust fixation of the surface element can be achieved if the retaining device has a clamping mechanism to fix the surface element to the retaining device by force or friction. It is practical if the retaining device is formed with the cover surface of the cover element or arranged on it.

[0045] It is advantageous if the holding device is designed to positively engage around an edge of the surface element in order to fix the surface element with the holding device. For this purpose, the holding element can have several, in particular two, holding arms, between which the surface element can be inserted such that the holding arms are arranged on opposite sides of the surface element. The holding arms can be designed to exert a pressing force on surfaces of the opposite sides in order to fix the surface element in a force-fitting or friction-fitting manner. Typically, the holding arms are designed to protrude from the covering surface. A robust construction can be achieved if the holding device or the covering arms are formed with a covering surface section of the covering surface, wherein the covering surface section is shaped such that it forms a groove into which an edge of the surface element can be positively inserted.It has proven to be effective if the furrow is essentially rectangular, square, U-shaped or V-shaped in cross-section.

[0046] Easy handling is achieved if one or more of the support elements are designed as hollow bodies, in particular hollow profiles. Alternatively or cumulatively, the coupling piece can be designed as a hollow body. Preferably, one or more of the support elements and / or coupling pieces are formed with or from metal, in particular a light metal, plastic, or a composite material. For ease of manufacture, it has proven advantageous if one or more of the support elements are designed as profiles, in particular structural profiles.

[0047] It is practical if the first and / or second support element has a mounting support connecting element which is designed to correspond in shape to a mounting support connecting rail of a mounting support in order to connect the support element to the mounting support in a form-fitting and / or force-fitting manner, in particular by inserting the mounting support connecting element onto or into the mounting support connecting rail. The mounting support generally serves to anchor a support element to an environmental element of an environment, for example a floor or a wall. For easy handling, it is advantageous if the mounting support connecting element is designed with a mounting support receptacle into which the mounting support connecting rail can be inserted in order to connect the support element to the mounting support in a form-fitting manner.A high level of robustness can be achieved if the mounting support receptacle is formed with a bore or a channel in the support element, into which the mounting support connecting rail can be inserted in a form-fitting manner. It is preferably provided that a longitudinal axis of the mounting support receptacle, in particular of the bore or the channel, runs essentially parallel to a longitudinal extent of the support element. Depending on the intended use, it can be advantageous if the mounting support receptacle is arranged essentially centrally or eccentrically in the support element in a cross-section that is orthogonal to the longitudinal axis of the support element, in particular with regard to a geometric center of gravity of the support element. The mounting support receptacle is preferably arranged eccentrically in the support element in such a way that it is arranged within the support element between a center, in particular a geometric center of gravity, of the support element and aThe second guide element is positioned on the opposite side of the supporting element. This allows the supporting element structure, for example in a balcony railing, to be positioned slightly offset from a position predetermined by a mounting support, so that the mounting supports pose less of an obstruction to a user during subsequent use. For example, a mounting support attached to a balcony can be positioned at a greater distance in front of a balcony floor slab.

[0048] For high stability, it has proven effective if the mounting support receptacle has a polygonal shape, in particular a triangle, rectangle or square, in a cross-section orthogonal to its longitudinal extent. High flexibility can be achieved if several mounting support receptacles are provided, wherein preferably one of the mounting support receptacles is arranged essentially centrally in the support element in the aforementioned manner and one of the mounting support receptacles is arranged eccentrically in the support element opposite the connecting element in the aforementioned manner. The aforementioned mounting support can in particular be part of the support element construction in order to connect the first and / or second support element to the mounting support. The mounting support usually has an anchoring device in order to fix the mounting support in a form-fitting and / or force-fitting manner to a surrounding element, usually a floor or a wall.

[0049] It is advantageous if a support rail is provided on which several mounting supports are arranged at a distance from one another, usually along a longitudinal axis of the support rail. In this way, the mounting supports can be positioned in a time-efficient and practical manner, in particular with a predetermined spacing. Supporting elements can then be connected to the mounting supports with little effort, in particular if a balcony railing is formed with the support element construction. The mounting supports can be connected to the support rail in a form-fitting, force-fitting and / or material-fitting manner. Preferably, the mounting supports are connected to the support rail in such a way that the longitudinal axes of the mounting support connecting rails of the mounting supports are aligned transversely, usually orthogonally, to the longitudinal axis or longitudinal extension of the support rail, usually parallel to one another.For simple assembly, it has proven effective if the mounting support connecting rails are arranged laterally along the longitudinal axis of the support rail in plan view, usually with the viewing direction parallel to the longitudinal direction of the mounting support connecting rails or transversely to the longitudinal axis of the support rail. It is advantageous if the support rail, particularly in plan view, has several notches transversely to the longitudinal direction, with one of the mounting support connecting rails being arranged at least partially, in particular completely, countersunk in each of the notches. In this way, one or more gaps, which are often present between the support rail and the interconnected load-bearing elements mounted on the mounting supports, can be reduced and / or the mounting supports can be protected from external loads. Typically, each mounting support connecting rail is assigned a notch and vice versa.This can be expediently implemented in that the retaining rail has one or more gap covering elements which protrude transversely to a longitudinal axis of the retaining rail from a base body of the retaining rail, wherein the incisions are formed by depressions in the gap covering elements and / or by spacings between the gap covering elements. The gap covering element can, for example, be formed with a strip, wherein a strip surface of the strip protrudes at an angle, in particular orthogonally, from the base body, usually to the side of the retaining rail on which the mounting supports are arranged. Gap covering elements are preferably arranged on an upper edge and / or lower edge of the retaining rail. A simple construction can be achieved if the base body is formed with a strip, wherein a strip surface of the strip is aligned substantially parallel to the mounting support connecting rails.The gap-covering elements then typically protrude at an angle, particularly orthogonally, to the plane of the strip. It is practical if the retaining rail, particularly the base body and / or the gap-covering elements, are formed with or from sheet metal.

[0050] The above is particularly practical if a balcony railing is formed with the supporting element construction, whereby in particular the retaining rail is mounted on a front edge and / or front surface of a balcony floor slab.

[0051] Advantageously, the support element construction comprises a plurality of second support elements, each of which is connectable or connected to the first support element via a coupling piece, in that a first guide system or second guide system is provided between the first support element and the coupling piece and between the second support element and the coupling piece in order to connect the support elements to the coupling piece in a form-fitting manner, such that both the first support element can be displaced in a guided manner relative to the coupling piece and the second support element can be displaced in a guided manner relative to the coupling piece in order to adjust a relative position of the first support element relative to the second support element. It is understood that the plurality of second support elements or coupling pieces can each be designed or connectable or connected to the first support element in accordance with the aforementioned features, characteristics and effects.

[0052] A high level of practicality can be achieved if a plurality of second support elements can be or are connected to the first support element via the same coupling piece, in particular in the aforementioned manner. For this purpose, the coupling piece generally has a second connecting element corresponding to the first connecting element of the first support element, as well as a plurality of further second connecting elements, each of which corresponds to a first connecting element of the second support elements. For example, the coupling piece can have three guide pins in order to form-fit a guide receptacle of the first support element via the coupling piece with guide receptacles of two second support elements by inserting one of the guide pins into one of the guide receptacles. In particular, in this way the second support elements can be connected to the first support element particularly easily at a predetermined distance and / or aligned parallel to one another.For high time efficiency during assembly, it is advantageous if, as described above, there is no positive connection between the coupling piece and the first or respective second support element in a direction orthogonal to the direction of displacement. Accordingly, for high robustness, it is expedient if an aforementioned deactivatable blocking device is present in order to block guided displacement of the coupling piece relative to the respective other support element in at least one of the displacement directions. For easy handling, it is advantageous if the coupling piece is designed as a coupling piece rod, wherein one long side of the coupling piece rod forms one of the second guide elements and the end pieces or wide sides of the coupling piece rod each form the other second guide element. The second guide elements are preferably designed as guide pins.It may be advantageous if, as described above, the first support element or one or more of the second support elements each have a recess with a plurality of guide receptacles, which are arranged one behind the other in the depth direction of the recess, in particular as described above. This enables particularly pronounced flexibility of use.

[0053] It is understood that the multiple second support elements may each have different characteristics, in particular sizes, shapes, and / or other features, in their specific design and are generally to be understood as equivalent or belonging to the same class only with regard to the features and effects according to the invention. Depending on the intended application, multiple second support elements may also be designed identically or with identical characteristics. This applies analogously to multiple first support elements. In particular, first support elements and second support elements may, in principle, be designed with identical or different features or characteristics.

[0054] It is expedient if the first guide system, with which the plurality of second support elements are each connected to the first support element by means of coupling pieces, has the same first guide element, preferably the same guide receptacle, on the first support element. This can be implemented in a simple manner in that the first guide element is designed to form a positive connection with a plurality of second guide elements, such that the second guide elements can be displaced in a guided manner relative to the first guide element. For example, the guide receptacle on the first support element can be designed such that the guide pins of a plurality of coupling pieces can be inserted into the guide receptacle and displaced in a guided manner therein. It is expedient if the individual guide pins can be fixed or locked in a desired position relative to the first support element or its guide receptacle using the respective locking devices.

[0055] Alternatively or cumulatively, the first support element can have further first guide elements, for example further guide receptacles and / or guide pins, in order to establish a guided, displaceable connection with second support elements, in particular in the aforementioned manner, via one or more first guide systems or second guide systems.

[0056] For flexible handling, it has proven useful if the first support element has a plurality of guide receptacles, which are arranged in particular on different, in particular opposite, sides of the first support element, in order to produce a guided, displaceable connection or a displacement state with one or more guide pins corresponding to the guide receptacle.

[0057] It is understood that it is expedient if one or more second support elements can be connected or are connected to one or more further first support elements by means of further coupling pieces in the manner described above.

[0058] In this way, depending on the application, a first support element can be connected in a flexible manner to a plurality of second support elements, wherein the displaceability provided according to the invention between the first support element and the respective second support elements enables a simple, practical, low-effort relative positioning of the support elements to one another, so that the support element construction can be erected with low stress and high error tolerance.

[0059] Advantageously, a support element assembly is provided, wherein the support element assembly comprises a plurality of interconnected support element structures according to the invention. In accordance with the aforementioned features and effects, a support element assembly formed with a plurality of support element structures, in particular the aforementioned ones, also exhibits a high degree of practicality and safety.

[0060] It is advantageous if the multiple support element structures are connected to one another, with at least one support element of a first support element structure and at least one support element of a second support element structure forming a further support element structure. This allows a modular system comprising a plurality of, in particular flexibly combinable, support element structures to be constructed flexibly depending on the application, whereby the advantageous effects of a single support element structure are also retained in an analogous manner for a support element composite.

[0061] A railing, in particular a balcony railing, is advantageously proposed, wherein the railing or balcony railing is formed with a plurality of interconnected railing support elements, characterized in that the railing support elements form a support element construction according to the invention or a support element assembly according to the invention. In this way, or by using the support element construction according to the invention or the support element assembly according to the invention to erect a railing, a railing with high practicality and safety can be erected. According to the aforementioned features and effects of a support element construction according to the invention or a support element assembly according to the invention, the railing can be erected with high practicality, ease of handling, and safety.By connecting the railing support elements in a form-fitting manner and allowing them to be moved relative to one another, initial positioning of the railing support elements relative to one another can be carried out with lower positioning accuracy and higher error tolerance, since precise adjustment of the balcony support elements in their final positions can only be carried out successively and / or at a later point in time during the erection of the railing, or positioning errors can be compensated for by readjustment. This advantageously reduces mechanical stresses in the railing support element structure. In particular, the use of conventional fasteners such as screws and rivets, which generally require precise positioning of drill holes, can be largely eliminated.This allows even a layperson to install the balcony railing, avoiding the typically time-consuming and costly task of hiring a professional to install the railing. This is especially true if the railing is designed as a balcony railing, especially since aspects of safety, robustness, and / or practicality are particularly important for a balcony railing.

[0062] Expediently, supporting elements of the railing or railing supporting elements can be designed in the form of, usually vertically aligned, columns, usually horizontally aligned, railing chords which connect the columns, railing rods which connect several railing chords to one another, and / or handrails which form an upper limit of the railing.

[0063] It has proven effective for the railing, particularly a balcony railing, to comprise at least two spaced-apart columns that are connected to one another by one or more railing chords, generally in a direction transverse to, and often orthogonal to, the longitudinal axes of the columns. The columns are each formed with a first supporting element, and the railing chords are each formed with a second supporting element, with the first supporting elements and second supporting elements each forming a supporting element structure. This creates a railing that can be erected and constructed in a practical manner and with high stability.

[0064] A high level of practicality can be achieved if the railing straps can be or are connected to the respective column via the same coupling piece, in particular in the aforementioned manner. In particular, in this way the railing straps can be connected to the columns particularly easily at a predetermined distance and / or aligned parallel to one another. For high time efficiency during assembly, it is advantageous if, as described above, there is no positive connection between the coupling piece and the first or respective second support element in a direction orthogonal to the direction of displacement. Accordingly, for a high level of robustness, it is expedient if an aforementioned deactivatable blocking device is provided in order to block guided displacement of the coupling piece relative to the respective other support element in at least one of the displacement directions.For ease of handling, it is advantageous if the coupling piece is designed as a coupling piece rod, with one longitudinal side of the coupling piece rod forming one of the second guide elements and the end pieces of the coupling piece rod each forming the other second guide element. The second guide elements are preferably designed as guide pins.

[0065] It is advantageous if the column, as described in particular above, is designed with a recess having a plurality of guide receptacles, preferably a guide receptacle upstream of the recess in the depth direction and a guide receptacle downstream of this in the depth direction, wherein the downstream guide receptacle usually has limiting elements which in particular separate the two guide receptacles from one another. As a result, as described above, a second support element, in particular a railing strap, can be positively displaceably connected to the column via a coupling piece, the guide pin segment of which is engaged behind the limiting elements or alternatively is not engaged behind. This depends in particular on whether the coupling piece or its guide pin segment is inserted into the upstream or downstream guide receptacles and / or depending on the design or shape of the coupling piece or its guide pin segment.Columns and / or railing chords or further first or second supporting elements of the railing can be designed in an analogous manner. It has proven particularly practical if one or more railing chords are connected to the respective column in such a way that, in the sliding state, a guide pin segment of the respective coupling piece is not engaged behind by limiting elements of the, in particular downstream, guide receptacle of the column or is designed in such a way that, in the sliding state, in a direction orthogonal to the sliding direction, in particular counter to a depth direction of the recess, there is no positive connection between the coupling piece or its guide pin and the, in particular downstream, guide receptacle of the column, so that the coupling piece can be detached from the column by moving the coupling piece orthogonal to the sliding direction. This enables particularly simple adjustment and assembly of the railing.For this purpose, the guide pin segment can be inserted into the upstream or downstream guide receptacle in the sliding state, in particular depending on the specific shape of the guide pin segment.

[0066] For this purpose, it is further expedient if the railing chords are connected to one another with one or more railing rods, generally in a direction transversely, in particular orthogonally, to the longitudinal axis of the railing chords and transversely, in particular orthogonally, to the longitudinal axis of the columns, wherein the railing rods are designed as further first supporting elements, which each form a supporting element construction with one or more railing chords.

[0067] A high degree of railing versatility can be achieved when railing chords and / or balusters feature one or more cover elements with retaining devices for securing a panel element as a passage barrier or as a field filler, usually in the form of a plate, between the railing chords or balusters. The panel element or field filler is usually made of glass, metal, or plastic and is usually made as a plate.

[0068] Further features, advantages, and effects will become apparent from the following exemplary embodiments. The drawings, to which reference is made, show: Fig. 1 a schematic representation of a balcony railing formed with several supporting element structures; Fig. 2 a schematic representation of a coupling piece of a load-bearing element construction; Fig. 3 a schematic representation of a load-bearing element of a load-bearing element construction; Fig. 4 bis Fig. 7 schematic representations of various supporting elements in a cross-section; Fig. 8 bis Fig. 13 schematic representations of various coupling pieces; Fig. 14 a schematic representation of a cover element of a supporting element construction; Fig. 15 bis Fig. 17 schematic representations of various cover elements in a cross-section; Fig. 18 und Fig. 19 schematic representations of mounting supports for a load-bearing element construction; Fig. 20 a schematic representation of another balcony railing formed with several supporting element structures; Fig. 21 a schematic representation of a support rail with mounting supports arranged on a balcony floor slab.

[0069] Fig. 1 shows a schematic representation of a section of a balcony railing 1, which is formed with several interconnected balcony railing support elements, wherein the balcony railing support elements form a support element construction or several interconnected support element constructions. Visible in Fig. 1 is a column 2, in particular a vertical column, on which a railing chord 3 is arranged, the longitudinal axis of which is aligned transversely, in particular orthogonally, to the longitudinal axis of the column 2. Connected to the railing chord 3 are a plurality of spaced-apart railing rods 4, the longitudinal axes of which are aligned transversely, in particular orthogonally, to the longitudinal axis of the railing chord 3, preferably parallel to the longitudinal axis of the column 2 or to a plane defined by the column 2 and the railing chord 3. A handrail 5 is arranged at an upper end of the column 2, aligned parallel to the railing chord 3. The column 2, the railing chord 3 and the railing rods 4 are each designed as a support element 6, with two interconnected support elements 6 forming a first and second support element 6 of a support element construction.In each case, two support elements 6 are connected to one another by means of a coupling piece 7, wherein in each case a guide system is present between the support element 6 and the coupling piece 7, which guide system connects the support element 6 and the coupling piece 7 in a form-fitting manner in such a way that the respective support element 6 can be displaced in a guided manner relative to the coupling piece 7. The respective guide system is formed with a guide receptacle 8 of the support element 6 and a guide pin 9 of the coupling piece 7 in order to form a guided, displaceable connection between the support element 6 and the coupling piece 7 by inserting the guide pin 9 into the guide receptacle 8. In this way, both support elements 6 connected to the coupling piece 7 can be displaced relative to the coupling piece 7 connecting them in order to set a relative position between the two support elements 6.For locking a support element 6 relative to the coupling piece 7, a locking device 10 is provided, which preferably effects a press connection between the coupling piece 7 and the support element 6.

[0070] As in Fig. 1 oder Fig. 3 As can be seen, the guide receptacle 8 of the support element 6 is preferably formed with a channel or a groove, the longitudinal axis of which is preferably aligned along a longitudinal extent of the support element 6, in order to enable a guide pin 9 inserted into the guide receptacle 8 to be displaced along the longitudinal extent of the support element 6. In order to establish a positively guided, displaceable connection between the guide receptacle 8 and the guide pin 9, the guide receptacle 8 has a plurality of limiting elements 11, each of which positively engages behind a guide pin segment of a guide pin 9 inserted into the guide receptacle 8.For this purpose, it is expediently provided that the guide pin 9 has a varying outer diameter in the form of limiting element receptacles 12, into which a limiting element 11 can be positively inserted, in order to establish a guided, displaceable connection between the guide receptacle 8 and the guide pin 9. The limiting elements 11 are preferably designed with or as rails, which extend in particular along a longitudinal axis of the guide receptacle 8, as can be seen in . Fig. 3 . In this way, it is possible for guide pins 9 of one or more coupling pieces 7 to be inserted into a guide receptacle 8 and to be displaceable in the guide receptacle 8 relative to the guide receptacle 8 along a longitudinal extent of the guide receptacles 8, and thus also for further support elements 6 connected to the coupling pieces 7. The coupling piece 7 generally has two guide pins 9 in order to produce a form-fitting, guided, displaceable connection, corresponding to the aforementioned embodiment, with one of the guide pins 9 to a guide receptacle 8 of a support element 6. If two support elements 6 are connected to a coupling piece 7 in this way, the two support elements 6 can be displaced relative to one another along guide directions or displacement directions predetermined by their guide receptacles 8, so that their relative position to one another can be flexibly adjusted.

[0071] In this way, the Fig. 1 The column 2 shown, each designed as a supporting element 6, the railing belt 3, the railing rods 4 and the handrail 5 are each connected to one another with coupling pieces 7 in the aforementioned manner, so that their relative positioning to one another can be flexibly changed or adjusted.

[0072] Fig. 2 shows a schematic representation of a coupling piece 7 of a supporting element construction, in particular a supporting element construction according to Fig. 1 The coupling piece 7 has interconnected legs, each of which forms a guide pin 9 for a positive connection with a guide receptacle 8 of a support element 6. The legs or their longitudinal axes are expediently arranged at an angle, in particular orthogonally, to one another in order to arrange support elements 6 connected to the respective legs at an angle corresponding thereto.

[0073] Continue in Fig. 2 Visible are limiting element receptacles 12 of the guide pins 9, into which limiting elements 11 of the guide receptacles 8 can be inserted when the guide pins 9 are inserted into a guide receptacle 8 to establish a positive connection. Two limiting element receptacles 12 are expediently provided on opposite sides of the guide pin 9, thereby forming a guide pin segment which can be engaged behind by the limiting elements 11 to establish the positive connection.

[0074] In order to fix or lock the guide pin 9 in its position relative to the guide receptacle 8 in a sliding state in which a guide pin 9 is inserted in a guided displaceable manner into a guide receptacle 8, a locking device 10 is provided. As shown in Fig. 2 As can be seen, the locking device 10 can be formed with a pressing element 15 designed as a screw, which can be inserted into a borehole 16 arranged on the leg or guide pin segment and penetrating the leg or guide pin segment and can be passed through the borehole 16 in order to establish a press connection of the pressing element 15 with a pressing element counter-surface of the guide receptacle 8 for locking in the displaced state by passing the pressing element 15 through the borehole 16. This is usually done in such a way that a section of the pressing element 15 protrudes beyond a borehole exit of the borehole 16 and is pressed against the pressing element counter-surface. The passing through usually takes place by screwing the pressing element 15 into the borehole 16, preferably into a thread of the borehole 16. It is understood that the locking device 10 can also be formed with several such screws or boreholes.It is expedient if each of the legs or guide pins 9 of a coupling piece 7 can be locked with a locking device 10.

[0075] Fig. 3 shows a schematic representation of a section of a supporting element 6 of a supporting element construction, in particular a supporting element 6 of the Fig. 1 . The guide receptacle 8 formed with a channel or groove is visible, into which a guide pin 9 can be inserted so that it can be displaced in a form-fitting manner in the guide receptacle 8.

[0076] In order to achieve a high level of robustness and safety, it is provided that the guide receptacle 8 is recessed in the support element 6 or in a recess 14 of the support element 6 designed as a groove. As in Fig. 3 As can be seen, the channel or groove of the guide receptacle 8 can be formed as part of the recess 14. One or more cover elements 18, shown in Fig. 14 bis Fig. 17 , which can be connected to the support element 6 in a form-fitting and / or force-fitting manner in such a way that they preferably completely cover an opening of the recess 14 or the guide receptacle 8 arranged in the recess 14 in the depth direction view, as can be seen in Fig. 1 .

[0077] Continue in Fig. 3 It can be seen that the support element 6 preferably has two mounting support receptacles 13, into each of which a mounting support connecting rail 23 of a mounting support 22 corresponding in shape to the mounting support receptacle 13 can be inserted in order to connect the support element 6 in a form-fitting and / or force-fitting manner to the mounting support 22. Exemplary mounting supports 22 corresponding to the mounting support receptacles 13 are shown in Fig. 18 und Fig. 19 The support element 6 has a centrally arranged mounting support receptacle 13, in particular for connection to the mounting support 22 according to Fig. 18 , and an eccentrically arranged mounting support receptacle 13 in the support element 6, in particular for connecting to the mounting support 22 according to Fig. 19 , each of which is formed with a channel in the longitudinal direction of the support element 6. Thus, depending on the specific requirements, the support element 6 can be arranged at a position predetermined by the mounting support 22 or offset from it.

[0078] Fig. 4 bis Fig. 7 show schematic representations of various supporting elements 6, in particular supporting elements 6 of the Fig. 1 , in a cross-section. Fig. 4 shows the supporting element 6 of the Fig. 3 in a cross-section. In Fig. 4 It can be seen that the support element 6 has fastening pin receptacles, which are designed to correspond in shape to fastening pins 20 on the cover element 18 in order to establish a positive or frictional connection between the support element 6 and the cover element 18 by inserting the fastening pins 20 into the fastening pin receptacles. The fastening pin receptacles are designed as grooves with a longitudinal extension along a longitudinal extension of the recess 14 or a longitudinal extension of the guide receptacle 8, whereby the cover element 18 can be flexibly positioned along the longitudinal extension depending on the application conditions.

[0079] In Fig. 4 it is shown that the support element 6 in the recess 14 can have two guide receptacles 8 one behind the other in the depth direction, referred to as upstream guide receptacle 33 and downstream guide receptacle 32. This is implemented in a practical way in that the limiting elements 11 define a recess area downstream of the limiting elements 11 in the depth direction of the recess 14 for forming the downstream guide receptacle 32 and a recess area upstream of the limiting elements 11 in the depth direction for forming the upstream guide receptacle 33 within the recess. The downstream guide receptacle 33 is suitable for engaging behind a guide pin segment inserted into it with the limiting elements 11 in the displacement state. The upstream guide receptacle 33 is suitable for forming a connection orCoupling between coupling piece 7 and support element 6 without engaging behind a guide pin segment inserted into the upstream guide receptacle 33 or to form it in such a way that in a direction orthogonal to the direction of displacement or counter to the depth direction of the recess 14 there is no positive connection between the support element 6 and the coupling piece 7, shown by way of example in . Fig. 20 .

[0080] It is understood that, in principle, the recesses 14 shown here can also each be formed with only a single guide receptacle 8, for example the upstream guide receptacle 33 or downstream guide receptacle 32, i.e. in particular with or without limiting elements 11.

[0081] A supporting element 6 with design according to Fig. 3 or Fig. 4 has proven particularly practical for forming the column 2, the railing belt or one or more railing rods 4.

[0082] Fig. 5 shows a further support element 6 in a cross section with a guide receptacle 8 or recess 14 according to Fig. 3 or Fig. 4 . The supporting element 6 of the Fig. 5 can basically have the same features and corresponding effects as the supporting element 6 of the Fig. 3 or Fig. 4 The supporting element 6 of the Fig. 5 has a curved outer surface on one side of the support element 6, which is opposite a side with the guide receptacle 8 or recess 14, in order to facilitate, in a use state, the guiding of a user's hand with the outer surface or the holding of the outer surface by a user. Preferably, in particular, the handrail 5 has a design according to Fig. 5 on.

[0083] Fig. 6 shows a further support element 6 in a cross section, comprising several guide receptacles 8 arranged in recesses 14. The support element 6 of the Fig. 6 , in particular its guide receptacles 8 and recesses 14, can basically have the same features and corresponding effects as the supporting elements 6 of the Fig. 3 bis Fig. 5 and their guide receptacles 8 and recesses 14. In contrast to the supporting elements 6 of the Fig. 3 bis Fig. 5 the supporting element 6 of the Fig. 6 several guide receptacles 8, each of which is arranged in a recess 14. The support element 6 of the Fig. 6 has a polygonal, in particular quadrilateral, cross-section. In principle, in particular in a cross-section of the support element 6, a guide receptacle 8 arranged in a recess 14 can be present on several, in particular each, sides of the support element 6. As shown in Fig. 6 It can be seen that it may be advantageous if the support element 6 has a mounting support receptacle 13 arranged in a cross section between one of the sides and a center, in particular the geometric center of gravity, of the support element 6 and a guide receptacle 8 arranged in a recess 14 is positioned on the other sides of the support element 6.

[0084] Fig. 7 shows a schematic representation of a support element 6 in a cross-section, comprising two guide receptacles 8 arranged in recesses opposite each other on the support element 6. The support element 6 of the Fig. 7 can basically have the same features and corresponding effects as the supporting elements 6 of the Fig. 3 bis Fig. 6 A support element 6 with a design according to Fig. 7 has proven particularly practical for forming one or more railing bars 4.

[0085] Fig. 8 bis Fig. 13 show schematic representations of different coupling pieces 7. The individual coupling pieces 7 can basically have the same features and corresponding effects as the coupling piece 7 of the Fig. 2 The coupling pieces 7 are formed with legs having a rectangular cross-section. Fig. 8 shows a coupling piece 7, which has a single blocking device and thus lies outside the scope of the invention, and which is formed with only one leg. Also visible is a locking device 10, formed with a worm screw as the pressing element 15. Fig. 9 und Fig. 10 show coupling pieces 7, which are formed with two interconnected legs, whose longitudinal axes form an orthogonal leg angle α to each other. The coupling piece 7 of the Fig. 10 corresponds to the coupling piece 7 of the Fig. 2 Each of the legs has a locking device 10, formed with a worm screw as a pressing element 15. It is understood that the locking device 10 can also have several such worm screws. The two legs each have a cuboid-like shape, which is formed with cover surfaces extending in the longitudinal direction of the legs and side surfaces connecting these at an angle, in particular orthogonally, in the longitudinal direction of the legs, wherein a cover surface has a larger area than a side surface, preferably the cover surface has an area more than twice as large as the side surface. The legs of the Fig. 9 are connected to each other in such a way that the respective side surfaces are aligned at an angle, in particular orthogonally, to each other. The legs of the Fig. 10 are connected to each other in such a way that the respective cover surfaces are aligned at an angle, in particular orthogonally, to each other. Fig. 11 bis Fig. 13 show coupling pieces 7 whose legs are connected to each other by a joint 17, so that the legs can be pivoted relative to each other about a rotation axis A. The coupling piece 7 of the Fig. 11 essentially corresponds to the coupling piece 7 of the Fig. 10 , whereby a leg angle α between the respective cover surfaces of the legs can be varied with the joint 17. The coupling piece 7 of the Fig. 12 essentially corresponds to the coupling piece 7 of the Fig. 9 , where a leg angle α between the respective side surfaces can be varied with the joint 17. The axes of rotation A of the joints 17 of the Fig. 11 and Fig. 12 are essentially aligned orthogonally to the longitudinal axes of the legs. Fig. 13 shows a coupling piece 7 with a joint 17 whose axis of rotation A is arranged such that it is orthogonal to the longitudinal axis of one leg and parallel to the longitudinal axis of the other leg. Fig. 8 bis Fig. 13 The coupling pieces 7 shown thus enable a multitude of possibilities for arranging two support elements 6 connected to a coupling piece 7 in a desired relative position to one another, depending on the intended use and the selection of a design of the coupling piece 7.

[0086] Fig. 14 shows a schematic representation of a cover element 18 of a support element construction for covering an opening cross-section of a recess 14 with the cover element 18. The cover element 18 is designed to be inserted into the recess 14 and fixed therein in a form-fitting and / or force-fitting manner. The cover element 18 is designed with a cover surface 19 which, when arranged on the cover element 18, covers an opening cross-section of the recess 14 or a recess width at least in sections, preferably entirely, in the depth direction of the recess 14. See also Fig. 15 . For fixing, the cover element 18 has two fastening pins 20, which are inserted into fastening pin receptacles 21 on the support element 6 or its recess walls, which correspond in shape to the fastening pins 20, as can be seen in Fig. 3 bis Fig. 7 , can be inserted. The fastening pins 20 are arranged in a cross section of the cover element 18 on opposite sides of the cover element 18 or the cover surface 19. Furthermore, in Fig. 14 It can be seen that the cover surface 19 is shaped in such a way that it forms a groove into which an edge of a surface element can be inserted in order to fix it to the support element 6 or between the support element 6 and another support element 6.

[0087] Fig. 15 bis Fig. 17 show schematic representations of various cover elements 18 in a cross-section. The cover elements 18 are essentially similar to the cover element 18 of Fig. 14 and its features and effects and differ only in the shape of the cover surface 19. Fig. 15 shows a cover element 18 whose covering surface 19 is formed as a plane. This serves, in particular, to robustly and securely cover the recess cross-section. A groove for receiving a surface element is not provided. Fig. 16 und Fig. 17 show cover elements 18 whose cover surfaces 19 have grooves which differ in the width of the groove in order to accommodate surface elements with different thicknesses.

[0088] Fig. 18 und Fig. 19 show schematic representations of mounting supports 22 for a supporting element structure. The mounting supports 22 serve to fasten a supporting element 6 or a supporting element structure to a surrounding element, such as a floor, for example a balcony floor or a balcony floor slab 28, or a wall. A mounting support 22 can have an anchoring foot 24 as an anchoring device for anchoring the mounting support 22 to a surrounding element, wherein the anchoring foot 24 can be designed to anchor the mounting support 22 to a surrounding surface which is transverse, in particular orthogonal, to the longitudinal axis of the mounting support 22 or parallel to it. Fig. 18 shows an anchoring foot 24, comprising a mounting plate arranged transversely, in particular orthogonally, to the longitudinal axis of the mounting support 22 or mounting support connecting rail 23, in order to anchor the mounting plate force-fittingly, in particular with screw connections, to a surrounding surface aligned substantially parallel to the mounting plate. Analogously, in Fig. 19 The mounting plate of the anchoring foot 24 is arranged parallel to the longitudinal axis of the mounting support 22. The mounting supports 22 each have a mounting support connecting rail 23, which is designed to fit positively into a mounting support receptacle 13 corresponding in shape to the mounting support connecting rail 23, as can be seen, for example, in Fig. 3 , of a support element 6 in order to connect the mounting support 22 in a form-fitting and / or force-fitting manner to the support element 6.

[0089] Fig. 20 shows a schematic representation of a section of another balcony railing 1, which is formed with several interconnected balcony railing support elements, wherein the balcony railing support elements form a support element construction or several interconnected support element constructions. The balcony railing 1 or the balcony railing support elements can be designed according to the balcony railing 1 or the support element constructions of the Fig. 1 or their characteristics and vice versa. This applies accordingly to the special designs of the Fig. 3 bis Fig. 7 and their characteristics. Visible in Fig. 20 is a, in particular vertically, aligned column 2, on which two railing chords 3 are arranged at a distance from each other, the longitudinal axes of which are aligned transversely, in particular orthogonally, to the longitudinal axis of the column 2, wherein ends of the railing chords 3 are connected to the column 2. A further column 2, to which the railing chords 3 are connected at their other ends, is shown for better illustration and clarity of a connection mechanism between railing chords 3 and columns 2 in Fig. 1 omitted. Between the railing chords 3, several spaced-apart railing rods 4 are arranged, with their longitudinal axes aligned transversely to the longitudinal axes of the railing chords 3, which connect the railing chords 3 to each other. In contrast to the balcony railing 1 of the Fig. 1 It is provided that the railing chords 3 are positively connected to the columns 2 via coupling pieces 7, wherein the two railing chords 3 are each connected to one of the columns 2 via the same coupling piece 7, i.e. a common coupling piece 7. The coupling piece 7 is designed as a coupling piece rod, wherein an end piece of the coupling piece rod protrudes positively into a guide receptacle 8 of the two railing chords 3 and a long side of the coupling piece rod can be positively inserted into a guide receptacle 8 of the respective column 2. The coupling piece rods are in Fig. 1 with oblique hatching. The end pieces of the coupling rod form guide pins 9 or guide pin segments, which are positively inserted into the respective guide receptacle 8 of the railing chords 3, and the long side of the coupling rod forms a guide pin 9, which can be or is positively inserted into the guide receptacle 8 of the column 2.

[0090] Another difference to the balcony railing 1 of the Fig. 1 lies in the fact that the coupling piece 7, particularly in the displaced state, is inserted into the guide receptacle 8 of the column 2 in such a way that the guide pin segment of the coupling piece 7 does not engage behind it, or in a direction opposite to the depth direction of the recess 14 of the column 2, there is no positive connection between the guide receptacle 8 of the column 2 and the guide pin 9. This can be implemented in a practical way by inserting the guide pin segment formed with the long side of the coupling piece 7 into the guide receptacle 33 of the column 2, which is arranged upstream of the recess 14 in the depth direction.Alternatively, it can be provided that a width of this guide pin segment is smaller than a spacing of the limiting elements 11 of the downstream guide receptacles 32 of the column 2 from one another in order to insert the guide pin segment between the limiting elements 11 into the downstream guide receptacle 32 without the guide pin segment being engaged behind by the limiting elements 11 in the displacement state.

[0091] It is understood that these two aforementioned differences of a common coupling piece 7 and a connection or coupling without engaging behind the guide pin segment opposite to the depth direction can also be present independently of one another or only individually.

[0092] In an analogous manner, a connection of the respective guide pin 9 or its guide pin segment to the respective railing belt 3 can also be carried out, wherein in particular the end pieces of the coupling piece rod are inserted in the respective displacement state into a, in particular upstream guide receptacle 33 or downstream guide receptacle 32 of the respective railing belt 3.

[0093] The combination of the jointly used coupling piece 7 for connecting the railing chords 3 to the respective column 2 and the possibility of inserting the coupling piece 7 into the respective guide holder 8 with little effort without reaching behind it enables a particularly high level of practicality when erecting the balcony railing 1.

[0094] To prevent the coupling rod or the guide pin 9 from sliding out or becoming detached from the respective guide receptacle 8 in a direction orthogonal to its displacement direction or counter to its depth direction - especially since these are not engaged behind by limiting elements - blocking elements 27 are inserted into the guide receptacles 8 of the respective other support elements 6, which block guided displacement of the coupling rod or the respective guide pin 9 inserted therein in this direction. The blocking elements 27 form a stop, which blocks guided displacement in the respective guide receptacle 8 in a direction that would lead to the guide pin 9 sliding out or becoming detached from the respective other guide receptacles 8.The blocking elements 27 can also be designed analogously to the aforementioned cover elements 18 and thus simultaneously cover a section of an opening of a respective guide receptacle 8. As shown in . Fig. 20 As can be seen, blocking elements 27 are inserted both in the guide receptacles 8 of the railing chords 3 and in the guide receptacle 8 of the column 2 in order to block a guided displacement of the coupling piece rods in the desired position.

[0095] Fig. 21 shows a schematic representation of a support rail 29 with mounting supports 22 arranged on a balcony floor slab 28. The mounting supports 22 can be arranged in accordance with the mounting support 22 of the Fig. 19 The retaining rail 29 has a plurality of mounting supports 22 arranged spaced apart from one another along its longitudinal extent, wherein mounting support connecting rails 23 of the mounting supports 22 are aligned orthogonally to the longitudinal extent of the retaining rail 29. The mounting supports 22 are positioned laterally on the retaining rail 29, usually on the outside with respect to the balcony. Thus, by mounting the retaining rail 29 on a balcony floor slab 28, mounting supports 22 can be fastened to the balcony floor slab 28 in a time-efficient manner and with a predetermined distance with little effort. By pillars 2 of a balcony railing 1, in particular a balcony railing 1 of the Fig. 1 or Fig. 20, are connected to the mounting support connecting rails 23, a balcony railing 1 with high practicality can be erected. The holding rail 29 expediently has gap covering elements 31, which protrude from a base body 30 of the holding rail 29 on the mounting support side. The gap covering elements 31 have notches, with one of the mounting support connecting rails 23 being arranged in each of the notches. In this way, a gap arising between the erected balcony railing 1 and the holding rail 29 or between the balcony railing 1 and the balcony floor slab 28 can be reduced. Gap covering elements 31 can expediently be arranged on an upper edge and / or lower edge of the base body 30.

[0096] A support element construction according to the invention, and in particular a balcony railing 1 formed therewith, can be erected with a high degree of practicality and safety. By ensuring that support elements 6 are each positively connected to one another in such a way that they are displaceable relative to one another, a relative position or arrangement of the support elements 6 can be changed or readjusted with little effort during erection, so that inaccuracies in alignment and / or positioning errors can be compensated or readjusted at a later time, especially without generating disadvantageous mechanical stresses in the structural design. This applies in particular to a balcony railing 1 formed with a plurality of interconnected support elements 6, so that small mispositionings between individual support elements 6 can accumulate to form larger deviations.The effort required for organizational planning or precise measuring prior to construction can thus be massively reduced. Furthermore, by arranging the guide recess 8 in a recess 14, a low-error and sustainably robust structure can be generated. Fasteners visible to a subsequent user, such as screws or rivets, can be largely avoided, resulting in a secure and aesthetically pleasing structure. This is especially true when cover elements 18 are used, which conceal the recess 14 or a guide recess 8 arranged in the recess 14. In particular, a load-bearing element construction or a balcony railing 1 constructed therewith can be erected and used with high practicality, ease of handling, high safety, and reduced construction effort.
