Description

Technical FieldThe following embodiments relate to a lifting-lowering belt for mounting a glass door, in particular for swing doors and comparable applications in the field of shower booths, interior fittings or furniture fittings, in which a controlled vertical movement is desired during the opening and closing of the door.Furthermore, the embodiments relate to a joint axle device, a bolt device, a first belt part and a second belt part for an aforementioned lifting-lowering belt.Background ArtIn the case of glass doors, for example in shower booths or in the elevated interior fitting, the problem frequently arises of a precise and at the same time low-maintenance mounting. Conventional door hinge belts often do not offer the possibility of performing a controlled height adjustment. If, therefore, irregularities in the floor or setting movements of the building occur, maladjustments can occur which impair the closing accuracy. In addition, a high sealing effect is desired especially in shower booths, which can be supported by a defined lowering movement during closing.Furthermore, users desire a flush-surface construction in which no components protrude from the glass pane. Such an embodiment facilitates cleaning and gives the design a modern, puristic aesthetic. A pendulum function on both sides is also advantageous in many cases, so that the door can be opened both inwards and outwards. This not only contributes to flexibility in confined spaces, but may also be safety-relevant (e.g. in an emergency).A further central aspect is the design for different stop situations. Many existing lifting-lowering belts must be manufactured and stored separately for left-hand stop, also known as DIN left, or right-hand stop, also known as DIN right, which poses high organization and economic challenges for manufacturers and dealers. If changes are required for a short time on the construction site, misfeedings or mis-orders have taken place or assembly errors occur, under certain circumstances no suitable band is available. This results in delays and additional costs.This results in the need for a lifting-lowering belt which, on the one hand, generates a defined lifting-lowering movement in order to improve the sealing effect and to reduce the wear, in particular of sealing profiles. On the other hand, a universal usability for DIN on the left and DIN on the right is to be provided with few manipulations without additional components or a completely different band having to be kept in stock.Proceeding from this situation, it is an object of the present invention to propose a lifting-lowering belt in which the height adjustment of the glass door can be improved and the mechanical load on the hinge axis device can be reduced. At the same time, it should be possible to strike the glass door on both sides and to design it flush, aesthetic and easy to maintain.Description - Technical SolutionThe present object is achieved by the features of the independent claims. Advantageous embodiments are specified in the dependent claims, the description and the drawings. If technically possible, the teachings of the subclaims or description features can be combined as desired with the teachings of the main and dependent claims.In particular, the object is accordingly achieved by a lifting-lowering belt for mounting a glass door, which belt has at least one first belt part with a mounting means arranged thereon, wherein the mounting means has a continuous vertical opening for mounting a hinge axis device. Furthermore, the lifting-lowering belt comprises at least one articulation axis device having a bearing vertical axis, wherein the articulation axis device is configured to connect the first belt part to a second belt part in a rotatably bearing manner. In this case, the joint axis device has a respective front side curve profile with at least one respective peak and one trough of the curve.The lifting-lowering belt further comprises at least one second belt part which has a U-shape with a base and two legs, wherein the second belt part is connected to the bearing means in a rotatably supporting manner at least indirectly via the articulation axis device. Each leg has in each case a leg horizontal recess designed for mounting a bolt device, and in each case a leg vertical recess for mounting the joint axis device. The joint axis device, its bearing vertical axis and the two limb vertical recesses are configured coaxially with respect to one another. In this case, the joint axis device forms a physical component and the corresponding limb vertical recesses each form a receptacle for this physical component, so that it is to be understood from the formulation that the axes of rotation of the joint axis device and of the limb vertical recesses substantially coincide. In other words, the bearing vertical axis corresponds to the axis of rotation or forms the mentioned axes of rotation.Furthermore, at least one bolt device is provided which is designed to be insertable selectively into one of the two leg horizontal recesses in order, in the inserted state into one of the two leg horizontal recesses, to interact with the curved profile of the joint axis device in such a way that a height offset of the second band part relative to the first band part is simultaneously associated with a rotation of the second band part relative to the first band part, in particular about the bearing vertical axis. In particular, the bolt device in the state inserted into the respective leg horizontal recess and the corresponding leg horizontal recess are configured coaxially with respect to one another. For example, both have a substantially circular cross section. It can also be that both components, in particular the leg horizontal recess, have a different cross-sectional geometry from the circular cross-section / t, for example an oval cross-section. In this case, the bolt device forms a physical component and the corresponding leg horizontal recess forms a receptacle for this physical component.In particular, the leg horizontal recess and the leg vertical recess meet each other and / or cross each other within a respective leg, so that components arranged therein, for example the joint axis device in the leg vertical recess and the bolt device in the leg horizontal recess, can interact with each other.In other words, the raising-lowering belt represents a hinge for a glass door, which allows a targeted raising-lowering movement during the opening and closing process. In this case, the special configuration of the joint axis device with a curved profile generates a height displacement which is guided via a bolt device in a leg horizontal recess. The second belt part with a U-shaped structure is rotatably connected to the first belt part, wherein a defined movement of the joint axis device is made possible by the vertical and horizontal recesses. The specific shape of the peaks and valleys influences the movement characteristic, so that the door opens and closes in a specific, advantageous manner. The U-shaped configuration of the second strap part with the two leg horizontal recesses formed for receiving the bolt device is particularly advantageous. Thus, the lifting-lowering belt can be converted from a lifting-lowering belt with left stop to a lifting-lowering belt with right stop by changing the bolt device from the bolt device receptacle / leg horizontal recess of the one leg into the bolt device receptacle / leg horizontal recess of the second leg, and vice versa. It is no longer necessary to produce or store two different lifting-lowering belts.An important advantage of the proposed lifting-lowering belt is its simple conversion from a left-hand stop (DIN left) to a right-hand stop (DIN right) without additional components. This adaptation can be carried out with few manipulations directly on site and increases both the flexibility during assembly and the economy in storage.For the purpose of changeover, the second strap part is first pivoted in the direction of the first strap part to such an extent that the bolt device located in the upper limb horizontal recess is accessible. This pin means is removed before the entire lift-down belt is rotated 180 degrees about the central horizontal plane of the lift-down belt. As a result, the previously upper leg reaches downward and the previously lower leg reaches upward. Subsequently, the bolt device is inserted into the now upper leg horizontal recess in such a way that it is again engaged with the front-side curved profile of the joint axis device.As a result of this simple mechanical adjustment, the lifting-lowering belt can be transferred from a DINlinks configuration to a DIN-right configuration and vice versa. The same band can thus be used equally for left- or right-stop doors without different band models having to be manufactured or stored. The change-over also does not require any special tools or complex assembly steps, which provides installers such as users with a considerable time saving and increased flexibility.A lifting-lowering belt is in particular a fitting which enables both a rotatable mounting and a controlled height adjustment of a door. In the present context, the lifting-lowering belt is designed in particular such that it carries out a lifting mechanism when the door is opened and a lowering mechanism when it is closed.A glass door is in particular a transparent door made of glass or laminated glass, which is typically used in shower booths, interior rooms or furniture. In the present context, the door can be mounted in particular as flush as possible without protruding fittings.A first strap part is in particular a part of the lifting-lowering strap, which is usually fixedly fastened to a fixed structure, for example to a wall or to a door frame, alternatively also to a fixed glass component. The first belt part carries the bearing means and serves as a connection for the joint axle device.A bearing means is in particular a component which is arranged on the first belt part and has a vertical opening for receiving the joint axis device. The bearing means can be fixed in one or more planes and forms the base for the rotatable bearing.A vertical opening is in particular a through opening which extends substantially in the vertical direction and serves for the positive and / or non-positive reception of the joint axis device. It enables a precise alignment of the joint axis device, so that a rotation and lifting process can take place along a defined axis.A hinge axis device is in particular a substantially cylindrical or elongated structural element which is arranged between the first and the second belt part and enables the rotational movement and the lifting-lowering movement. It has a curved profile on each end face in order to bring about the defined raising and lowering in conjunction with the bolt device. In other words, the articulation axis device has two front-end regions, each of which has the curved profile. In particular, the joint axis device has a bolt device guide head with a curved profile at one or both end / s. In particular, one bolt device guide head or both bolt device guide heads are each a detachably fastenable or detachably fastened component of the joint axle device, so that in the event of wear individual component replacement can take place in an environmentally friendly manner instead of a complete strip replacement. Furthermore, the cam profile and thus the lifting-lowering behavior can thereby be adjusted according to requirements by a corresponding bolt device guide head selection. As a result, a lifting-lowering belt can be recycled and then adapted to different conditions, for example different ground heights or glass pane lengths, which is likewise detrimental to the environment. In particular, the joint axle device or any bolt device guide head or both any bolt device guide heads can be designed as a hollow profile / s, or solid profile / s or hollow profile / s with end termination.A bearing vertical axis is in particular the principal axis of rotation of the joint axis device, which is oriented vertically. About this axis, the rotational movement of the second belt part relative to the first belt part takes place, while additional elements in the context of the curve profile generate the lifting-lowering moment.A curve profile is in particular a formation-determining region, preferably circumferentially, on one or both end face / s of the articulation axis device, which is formed curved or wavy in at least one dimension. The cam profile is arranged at the end face at each end of the articulation axis device, interacts with the bolt device and brings about the vertical movement during the opening and closing.A peak is in particular an elevation point or section within the circumferentially running curve profile, the slope of which influences the upward movement of the bolt device. It serves to lift the bolt device when the two belt parts are rotated relative to one another. This range determines, among other things, the maximum height to which the second belt part is raised during the opening movement. Although a peak has an inclination and a gradient, the peak in the present case is in particular that section of the curve profile with increasing gradient from zero position; that is to say that section of the peak which brings about the upward movement of the second belt part.A trough of a curve is in particular a depression point or section, having a portion of a gradient, in the circumferentially running curve profile into which the bolt device runs when the two belt parts are rotated. The cam valley can define the latching position or a lower end position, for example, so that the door can remain lowered in a closed position. Although a peak has an inclination and a gradient, the bottom of the curve in the present case is in particular that section of the curve profile which starts with decreasing inclination from the peak; that is to say that section of the valley which brings about the downward movement of the second belt part.A second belt part is in particular a further element of the lifting-lowering belt, which is rotatably connected to the first belt part. The second band part is embodied in a U-shape and serves in particular for fastening or receiving the glass door leaf. It takes over the defined raising and lowering during rotation.A U-shape is in particular an embodiment of the second band part in which a base protrudes from two parallel legs and forms a contour similar in cross section to "U". The legs are preferably parallel, but not necessarily. U-like structures, for example a "V" with a point-like base, are also possible. This U-shape provides space for the bearing means and the hinge axis device between the legs, while the base provides stability in particular and connects the legs in particular.A base is in particular the connecting section between the two legs of the second band part. Via the base and / or via the legs, the second strap part can be attached to the glass door or to supplementary fastening components. The base may also include structural reinforcements.Legs are in particular two substantially parallel running regions of the second strap part, which laterally encompass the bearing means together with the articulation axis device. Alternatively, an angle between the legs is also possible. The legs have a leg horizontal recess and a leg vertical recess in order to accommodate the bolt device and the joint axis device. The horizontal leg recess and the vertical leg recess of a leg are in particular orthogonal to one another with their main axes. In particular, the vertical leg recess is oriented on the vertical band axis of rotation, preferably parallel or axis-identical.A leg horizontal recess is in particular a respective bore or milling in the legs, which extends horizontally or is at least predominantly oriented in the horizontal direction. The bolt device can be inserted into this recess so that it can come into contact with the curved profile.A leg vertical recess is in particular a respective substantially vertically extending bore or milling in the legs, via which the joint axis device is coaxial to the bearing vertical axis. This recess results in a defined positioning and rotational guidance about the vertical axis of rotation of the belt.A bolt device is in particular a structural element which can be inserted into the horizontal recess and which contacts the curved profile via the shape or position. The bolt can be formed in one or more parts, for example as a fitted screw, pin or screw pin, and guides the movement along the curved contour during rotation.A height offset is in particular the vertical difference which the second belt part, and thus the glass door, passes between the closed and open states. The height offset is a direct result of the interaction between the bolt device and the cam profile and brings about the intended raising or lowering.The previously defined object can thus be achieved at least by the features of claim 1, since a precise control of the height offset during the rotational movement is achieved by the interaction of the bolt device with the cam profile. This enables an improved functionality of the belt, in particular with regard to an automatic closing movement or an improved sealing of the door. At the same time, the exchangeable positioning of the bolt device allows the same type of belt to be used both for DIN on the left and for DIN on the right, which considerably reduces storage and production costs and allows the assembler to easily re-fit on site.Thus, a lifting-lowering belt, in particular a flush pendulum door lifting-lowering belt, for supporting a glass door, in particular a frameless all-glass door such as a shower cabin door, is proposed in particular. The lifting-lowering belt is designed such that it has an integrated lifting-lowering mechanism and can be used as both a DIN-left and a DIN-right door belt. In particular, this is achieved by a symmetrical construction of all essential components, whereby left-right adjustability is provided. In other words, the band can be changed over from one stop direction, for example on the left, to the other, for example on the right, and vice versa with little effort, without special additional components being required.The lifting-lowering belt is designed as a pendulum door belt, for example, so that the glass door can be opened in both directions, i.e., inward and outward. This offers the advantage, for example, in a shower, that no water drips onto the bathroom floor when it is opened to the inside. The flush-surface construction ensures in particular that in the closed state no components protrude into the interior of the shower region; the inner side of the glass door and the fitting fastened thereto form a continuously planar surface which can be easily cleaned, for example by means of a water slide or a type-like water scraper. This results in an appealing appearance and no dirt edges can be produced.The integrated lifting-lowering mechanism brings about a slight lifting of the door leaf when the door is opened and a corresponding lowering when the door is closed, due to the interaction of the cam profile and the bolt device. In this way, in the closed state, the door leaf can rest on the sleeper or the base with a seal attached at the bottom, so that a high water-tightness is achieved. During opening, the seal is relieved by the lifting, which minimizes friction and wear on the seal and permits easy opening.Naturally, each horizontal leg recess can have its own bolt device arranged therein, which is fixed accordingly if necessary and after appropriate positioning of the lifting-lowering belt, so that the basic idea remains fulfilled. Preferably, however, a single bolt device is repositioned. In other words, it is important that a bolt device is engaged with the cam profile, so that the lifting-lowering mechanism is formed.The above-mentioned universality saves storage capacities, reduces production and transport costs and makes installation on site significantly more flexible.Insofar as recesses are mentioned, these can be understood in principle as openings. It is not absolutely necessary for these to be produced by material removal. It can be that the component is cast, pressed or otherwise produced directly with the recess; for example, removal is also possible, in particular by means of machining.The phrase "substantially" means that the term following the phrase is to be satisfied in the nucleus, but even slight deviations are permissible. However, preference is always given to the complete fulfilment of the term "substantially" following the formulation.If ordinal numbers, for example "first", "second", etc., are used, for example for designating a component, an element, a method step or a method action, these ordinal numbers are provided purely for differentiation in the designation and do not indicate dependencies or orders. That is to say, in particular, that, for example, a device does not have to have a "first component" in order to have a "second component".Advantageous aspects are explained below and preferred modified embodiments are described further below. Explanations, in particular regarding advantages and definitions of features, are basically descriptive and preferred, but non-limiting examples. Where an explanation is limiting, this is expressly mentioned.Alternatively or additionally, it can be provided that the first belt part, the joint axis device and / or the second belt part is / are formed substantially mirror-symmetrically with respect to a central horizontal plane of the lifting-lowering belt. The production can be simplified by a mirror-symmetrical embodiment of individual or all strip parts, because different components are not required for left and right. Symmetry also allows for pleasing optics, as substantially the same components can be used for both left and right versions. In addition, a symmetrical geometry increases serviceability because certain components can be easily replaced or transferred to the other side without having to undertake extensive adaptations. This leads to cost-optimized series production and at the same time reduces inventory.Alternatively or additionally, it can be provided that the bolt device is formed in multiple parts, in particular from a screw and a pin, or in one part as a fitted screw, in order to enable flexible mounting. The bolt device plays a key role in the transmission of force from the curved profile to the second belt part. A multi-part design, for example a screw plus pin, allows fine adjustment if it is desired to compensate for different component tolerances. At the same time, a cost-effective one-piece fitted screw solution can be offered if particularly rapid assembly or lower production costs are of primary importance. Manufacturers can thus react flexibly to different customer requirements, for example if a particularly high load handling or an improved adjustment possibility is desired.Alternatively or additionally, it can be provided that the curve profile has a waveform with different curve peaks and / or curve slopes. The wave-shaped configuration of the curve profile enables individual adjustment of the lifting-lowering behavior to specific requirements, e.g. door weight, desired closing characteristic or sealing pressure. Different slopes in peak or valley curve areas provide a stepped lifting action. This can allow, for example, a first moderate approach stroke during opening, followed by a more pronounced stroke in a further rotational position. Latching effects can also be incorporated in a targeted manner by varying slopes.Alternatively or additionally, it can be provided that the joint axis device is formed monolithically or integrally, in particular releasably integrally. A monolithic joint axis device, e.g. made from a metal block or manufactured by casting, promising high stability and dimensional accuracy because welded seams, screw connections or adhesive joints can be dispensed with. This reduces potential vulnerabilities and minimizes maintenance effort. At the same time, one-piece production is cost-effective when large series is produced and in practice is particularly robust with respect to mechanical loads, as occur during frequent swinging of a glass door.Alternatively or additionally, it can be provided that the joint axis device has a joint axis and, on the end face, two bolt device guide heads arranged on the joint axis, wherein each bolt device guide head has, on the end face, a curved profile. If two bolt device guide heads with a curved profile are formed at the two ends (at the end face) of the articulation axis device, a symmetrical load distribution is achieved. This embodiment is particularly recommended in the case of larger or heavier glass doors, since the force absorption is distributed over two regions. Moreover, the dual design of the cam profile offers a redundant mode of operation: should one side wear, at least a certain basic function of the lifting-lowering mechanism remains. Furthermore, a fine adjustment of the door position can be effected via the different positions of the bolt device on the two heads.Alternatively or additionally, it can be provided that the curved profile has at least one or more latching positions for the bolt device in order to hold the glass door in the closed position. By means of one or more defined latching positions, the door leaf can be held securely in a specific position, in particular in the closed position. This is advantageous in shower enclosures so that the door does not open unintentionally. Alternatively or additionally, latching in an open position can be realized, for example for cleaning work. The latching also reduces the effort required to hold the door and thus increases user comfort.Alternatively or additionally, it can be provided that the curve profile has at least two, in particular exactly two, peaks of the curve and at least two, in particular exactly two, valleys of the curve as a continuous waveform. A curved profile with exactly two elevations and two depressions offers a particularly compact design, in which different intermediate positions of the door are nevertheless possible. Thus, for example, a first peak can produce an initial lifting when opening slightly, while the second peak produces an even higher lifting when opening further. Two defined curve valleys can represent separate latching or rest positions. This simplifies the design and lowers production costs, since a complicated, multiple wave contour is not required.Alternatively or additionally, it can be provided that the curve profile has an even plurality of peaks and an even plurality of valleys as a continuous waveform. An even number of elevations and depressions enables a symmetrical construction of the curved profile. This is particularly appropriate for pendulum doors, since the behavior can be uniformized in two pivot directions (inward and outward). As a result, the lifting-lowering belt can have similar lifting and lowering properties in both rotational directions. This synergy makes it particularly comfortable for users, since the door can be opened selectively in both directions with the same feel.Alternatively or additionally, it can be provided that the curve profile has at least two diametrically opposite peaks and valleys. Diametrically opposed formations in the curve profile provide a defined balance between two pivot directions. This is very useful in the case of a door that can be swung on both sides, because the same mechanism comes into effect when it opens to the left or to the right. The symmetrical construction simultaneously simplifies the assembly on site, since the profile has the same lifting and lowering properties in all relevant positions. Moreover, uniform wear is achieved because the load distributes itself to two opposing regions. Also, the raising-lowering belt can be used in this manner in particular as both a left belt and a right belt without deviating in the pivot properties.Alternatively or additionally, it can be provided that the curved profile has at least two or more diametrically opposite curved troughs in order to automatically keep the glass door in the closed position. If diametrically opposed valleys are in the structure, the door can be positioned in a closed position in both directions. This enables, among other things, a pendulum function on both sides, in which the door automatically returns to the closed position from both directions. This is very desirable, for example, in shower applications, so that the door does not remain open and water leakage is prevented. Moreover, uniform wear is achieved because the load distributes itself to two opposing regions. Also, the raising-lowering belt can be used in this manner in particular as both a left belt and a right belt without deviating in the pivot properties.Alternatively or additionally, it can be provided that at least one peak of the curve, preferably a plurality of peaks of the curve, particularly preferably all peaks of the curve each have a flattened portion. The respective flattened portion on the peaks is arranged in particular at the highest point of the slope of the peak, serves as a locking position and preferably reduces the friction at the contact point between the bolt device and the curve profile and facilitates a smooth transition between different locking or height positions. This advantageously not only protects the components involved, but also has a positive effect on the ease of operation. A uniform engagement or disengagement is produced, as a result of which in particular less jerking or click noises occur.Alternatively or additionally, it can be provided that the lifting-lowering belt has at least one spring element and / or damping element in the region of the articulation axis device or the bolt device in order to assist or damp the opening and / or closing. By integrating a spring, the band can be additionally supported during opening, in that the spring stores energy and releases it again during closing. Conversely, a damping element, e.g. a hydraulic or pneumatic damper, can prevent the door from striking too quickly. These measures increase safety, especially when children or older people are operating the door, and reduce the mechanical stress. The low-maintenance service is maintained despite these additional elements, provided that the components are robust for use in moisture or wet conditions, e.g. in shower booths.Alternatively or additionally, it can be provided that the second belt part is designed for pivoting the glass door open on both sides, so that the glass door can be pivoted out of the closed position both in a first direction and in an opposite direction. A pendulum function on both sides increases the operating comfort in rooms with a limited space available and improves safety because the door opens in both directions in an emergency. In hotel bathrooms, sauna areas or barrier-free sanitary installations, this is of particular advantage. The universal applicability of the band is thereby additionally increased, since no special fitting is required for a one-sided opening. Together with the possibility of using the band on the left or on the right, a flexible solution is produced which covers a wide variety of installation constellations.Alternatively or additionally, it can be provided that at least one or more stop means is / are provided, which limits the rotation of the second belt part in at least one or both rotational directions. Stop means ensure that the door is not opened beyond a certain angle in order to avoid collisions with walls, furniture or other components. This is important especially in narrow construction situations. Such stops can be realized mechanically, e.g. a pin, which engages in a recess, or integrated in the curved profile.Alternatively or additionally, it can be provided that the second band part and the first band part are formed such that in a closed position they are substantially flush with one another. The closed position is understood to be the zero position of the lifting-lowering belt. Flush designs are in the trend of modern architecture and bath equipment because they are aesthetic and offer hygienic advantages (easier cleaning). In addition, potential deposits of dirt or lime on protruding edges are dispensed with. The design requires a precise adjustment of the belt geometry, which is, however, favored by the described lifting-lowering technique.Alternatively or additionally, it can be provided that an adjusting means is provided in order to readjust the position of the second belt part relative to the first belt part in a transverse direction or in the direction of the vertical axis. Subsequent adjustability increases the service life of the overall system and makes it possible to compensate for tolerances in the assembly environment. If the building sets or the door is minimally distorted, the engineer can correct the position of the second belt part by means of a screw, eccentric bolt or other mechanism. This allows the closing pattern to be maintained permanently and increases the functional reliability (in particular tightness and secure closing stop). This is a distinct competitive advantage because problems due to distorted doors or clamping are reduced.Alternatively or additionally, it can be provided that the joint axle device is designed with two bolt device guide heads at the ends and a narrower axle section lying therebetween in a substantially dumbbell-shaped manner. The dumbbell-shaped design of the hinge axis device ensures efficient force transmission because the wider region at the ends, or the guide heads, serves as a contact zone for the bolt device, while the narrower middle part leaves a certain freedom of movement for the pivoting and raising-lowering function. This construction increases the stability and reduces the risk of bending stresses in the center. Moreover, the assembly is not problematic, since the bolt device can be threaded onto or through the outer heads, while the central axle section can easily be inserted into the vertical opening. Here too, the advantage of universal alignment is evident: the dumbbell-shaped geometry can be used without problems on the left as on the right.Alternatively or additionally, it can be provided that the lifting-lowering belt, in its operating state, i.e. after the mounting of the lifting-lowering belt or after its mounting state, has exactly one bolt device in the upper leg horizontal recess. In this case, the lifting-lowering strip, in its mounted state in the second limb horizontal recess, additionally has a second bolt device which prevents a vertical offset between the first strip part and the second strip part during the mounting or before completion of the mounting. For this purpose, in the assembled state of the lifting-lowering belt, its components, in particular both bolt devices, are arranged in the leg horizontal recesses in such a way that they are each arranged lying in the curve trough of the curve profile assigned to them. The operating state here is in particular the state when the lifting-lowering belt, for example supporting a glass pane, is in daily operation. The mounting state is that state before the lifting-lowering belt is fastened, in particular screwed, with its first belt part to its final underlying surface. In particular, the lifting-lowering strap changes from the mounted state into the operating state after the first strap part is fastened, in particular screwed, to its final underlying surface and / or after the lower bolt device has been removed from the lower leg horizontal recess. The lower bolt device thus loses the blocking function, which is attributable to the fact that without this second bolt device the first band part must be held high in a stabilizing manner during assembly. Without this lower bolt device, the band parts must therefore, according to an exemplary embodiment, first be aligned and screwed onto the plate body to be mounted, in particular designed as a glass door. The panel body is then brought into the desired position and aligned, in particular by means of levelers and / or glazing blocks. Finally, the positions of the bore holes for the first band part are marked. It is problematic here that without the present idea the first band part must be actively kept high. After marking the boreholes, the plate body is repositioned, the holes are drilled and the plate body can be mounted. It is conceivable that instead of using bore holes, alternative fastening methods can also be used, for example welding. In particular, in the delivery state of the lifting-lowering belt, both bolt devices are mounted or at least attached for mounting. The bolt devices block the lifting-lowering mechanism and the lifting-lowering belt cannot move upwards or downwards, or can only move downwards to a very limited extent; this means relative to the first belt part. Consequently, it is not yet decided whether the lifting-lowering belt DIN is formed to the right or DIN to the left. Thus, the assembler can mount the raising-lowering belt as if it had no raising-lowering function. As soon as the assembler removes, in particular screws out, the blockage of the raising-lowering function is removed and the raising-lowering band functions as described in the further present disclosure, in particular adjustably as DIN on the right or DIN on the left, depending on the installation position. In other words, the lower bolt device is to be removed for the transition from the mounting state to the operating state, regardless of whether the lifting-lowering belt DIN is to be used on the right or DIN on the left. The assembler can as a result fasten or in particular screw the lifting-lowering band to the underlying surface in particular more easily because the first band part, in particular designed as a screw-on plate, is able to stand or would be standing in the non-lifted / vertically offset position.The features listed allow a variety of configurations to more readily adapt the proposed hoist-lowering belt to different installation and use cases. In particular, the features that can be combined, such as a symmetrical configuration, a single-part or multi-part bolt device, wavy curved profiles and / or integrated spring elements or stop means, lead to high flexibility and low maintenance.
