Lift hinge for supporting a glass door

Abstract

A lift hinge (10) for supporting a glass door comprises a first hinge part (12) with a bearing device (14) having a vertical opening (14a) in which a pivot shaft assembly (16) with a vertical bearing axis (16a) is rotatably accommodated. A curved profile (17) on an end face of the pivot shaft assembly (16) together with a bolt assembly (26) in a leg (22, 24) of a second hinge part (18) effects a lifting movement of the glass door. In the process, a rotation of the second hinge part (18) relative to the first hinge part (12) causes a predetermined lifting or lowering of the door, thus achieving an improved sealing effect and reduced wear. By means of a mirror-symmetrical design, a bolt assembly (26) which can be formed as a single piece or in multiple parts, a stop position in the curved profile (17) and the ability to be rotated open on both sides, a flexible and low-maintenance application is possible.

Description

Technical Field

[0001] The following description relates to a lift hinge for supporting glass doors, particularly for revolving doors and similar applications in the fields of shower rooms, interior design, or furniture construction, wherein controlled vertical movement is required during opening and closing of the door.

[0002] Furthermore, this specification relates to the pivot assembly, bolt assembly, first hinge portion, and second hinge portion used in the aforementioned lifting hinge. Background Technology

[0003] DE202007001139U1 discloses a shower enclosure having a hinge in which a lifting mechanism is integrated. The lifting mechanism includes two cam discs coaxially mounted on a hinge pin, wherein adjacent cam surfaces of the two cam discs abut against each other when the door element is rotated open, causing the door to be vertically lifted. The door element is rotatable in two directions about a vertical pivot axis.

[0004] For glass doors, such as those in shower rooms or high-end interior designs, there is often a need for precise and low-maintenance support. Traditional door hinges typically do not allow for controlled height adjustment. Therefore, uneven floors or building settlement can lead to misalignment, compromising closing accuracy. Furthermore, a good seal is particularly important in shower rooms, which can be supported by a predetermined downward movement during closing.

[0005] Furthermore, users appreciate flush-mounted designs with no parts protruding from the glass panel. This design facilitates cleaning and gives the structure a modern, minimalist aesthetic. In many cases, the bidirectional rotating function is also advantageous, allowing the door to open both inwards and outwards. This not only contributes to flexibility in confined spaces but also improves security (e.g., in emergencies).

[0006] Another key aspect is the design for different hinge arrangements. Many existing lifting hinges must be manufactured and stored separately for either left-hand hinges (also known as DIN left) or right-hand hinges (also known as DIN right), posing significant organizational and economic challenges for manufacturers and distributors. If changes are needed on-site in a short period, if there are delivery errors or order mistakes, or if installation errors occur, suitable hinges may not be available. This leads to delays and additional costs.

[0007] This creates a demand for lift hinges that, on the one hand, produce a predetermined lifting motion to improve sealing and reduce wear, particularly on the sealing profile. On the other hand, these lift hinges should provide universal compatibility for both DIN left and DIN right hinges through just a few simple steps, without requiring additional parts or stock of entirely different hinges.

[0008] Given this situation, the aim is to propose a lifting hinge that improves the height adjustment of glass doors and reduces the mechanical load on the pivot assembly. Simultaneously, it should allow for installation of the glass door on either side and be designed to be flush with the surface, aesthetically pleasing, and easy to maintain. Summary of the Invention

[0009] The objectives of this disclosure are achieved through the features of various embodiments. Advantageous embodiments are described in the specification and drawings. Where technically feasible, features of one embodiment may be combined with features of another embodiment in any manner.

[0010] Specifically, the objective is thus achieved by a lift hinge for supporting a glass door, the lift hinge comprising at least one first hinge portion having a support device disposed thereon, wherein the support device includes a continuous vertical opening for supporting a pivot assembly. Furthermore, the lift hinge includes at least one pivot assembly having a vertical support axis, wherein the pivot assembly is configured to rotatably connect the first hinge portion to a second hinge portion. In this case, the pivot assembly includes a curved profile having at least one curved peak and at least one curved groove on each end face.

[0011] The lifting hinge also includes at least one second hinge portion having a U-shape with a base and two legs, wherein the second hinge portion is rotatably connected to the support device at least indirectly via a pivot assembly. Each leg includes a corresponding horizontal leg recess and a corresponding vertical leg recess, the horizontal leg recess being configured to support the bolt assembly, and the vertical leg recess supporting the pivot assembly. The pivot assembly, the vertical support axis, and the two vertical leg recesses are coaxial with each other. In this configuration, the pivot assembly forms a physical component, and the corresponding vertical leg recesses each form a receiving portion for that physical component, such that, as will be understood from the description, the axes of rotation of the pivot assembly and the vertical leg recesses are substantially coincident. In other words, the vertical support axis corresponds to or forms the aforementioned axis of rotation.

[0012] Furthermore, at least one bolt assembly is provided, configured to selectively insert into one of the two horizontal leg recesses to interact with the curved profile of the pivot assembly upon insertion into one of the two horizontal leg recesses, causing the second hinge portion to rotate relative to the first hinge portion (particularly about the vertical support axis), accompanied by a vertical offset of the second hinge portion relative to the first hinge portion. Specifically, when the bolt assembly is inserted into the respective horizontal leg recess, the bolt assembly and the respective horizontal leg recess are coaxial with each other. For example, both have a substantially circular cross-section. Alternatively, the two components (particularly the horizontal leg recesses) may have a cross-sectional geometry different from a circular cross-section (e.g., an elliptical cross-section). In this case, the bolt assembly forms a physical component, and the respective horizontal leg recess forms a receiving portion for that physical component.

[0013] In particular, the horizontal leg recesses and vertical leg recesses are adjacent to and / or intersect each other within the respective legs, such that the components arranged therein (e.g., the pivot assembly in the vertical leg recess and the bolt assembly in the horizontal leg recess) can interact with each other.

[0014] In other words, a lift hinge is a hinge used for glass doors that enables controlled lifting motion during opening and closing. A special design with a curved profile in the pivot assembly produces vertical displacement guided by bolt assemblies passing through horizontal leg recesses. A second hinge section with a U-shaped structure is rotatably connected to the first hinge section, whereby the vertical and horizontal leg recesses allow for predetermined movement of the pivot assembly. The specific shapes of the curved peaks and grooves influence the motion characteristics, allowing the door to open and close in a specific, advantageous manner. A particular advantage here is the U-shaped design of the second hinge section with two horizontal leg recesses (formed to accommodate the bolt assemblies). Therefore, by changing the bolt assembly from the bolt assembly receiving section / horizontal leg recess of one leg to the bolt assembly receiving section / horizontal leg recess of the other leg, the lift hinge can be converted from a left-hand hinged lift hinge to a right-hand hinged lift hinge, and vice versa. There is no longer a need to produce or stock two different lift hinges.

[0015] The key advantage of the proposed lifting hinge is that it allows for a simple conversion from a DIN-left configuration to a DIN-right configuration without requiring additional components. This adjustment can be achieved directly on-site in just a few steps, improving flexibility during installation and cost-effectiveness in inventory management.

[0016] To perform this transition, first rotate the second hinge portion toward the first hinge portion until it is close to the bolt assembly located in the recess of the upper horizontal leg. Remove the bolt assembly, and then rotate the entire lifting hinge 180 degrees about the central horizontal plane of the hinge. As a result, the previous upper leg moves downward and the previous lower leg moves upward. Then, insert the bolt assembly into the now upper horizontal leg recess so that it once again engages with the curved profile on the end face of the pivot assembly.

[0017] With this simple mechanical adjustment, the lifting hinge can be converted from a DIN-left configuration to a DIN-right configuration, and vice versa. Therefore, the same hinge can be used for both left-hand and right-hand hinged doors without the need to manufacture or stock different hinge models. Furthermore, the conversion requires no special tools or complex installation steps, providing significant time savings and increased flexibility for installers and users alike.

[0018] Specifically, lift hinges are accessories that enable both rotatable support and controlled height adjustment of a door. In this case, the lift hinge is specially designed to act as a lifting mechanism when the door is opened and a lowering mechanism when the door is closed.

[0019] Specifically, glass doors are transparent doors made of glass or laminated glass, typically used in shower rooms, interior spaces, or furniture. In this case, the door can be installed as flush as possible, without any protruding hardware components.

[0020] Specifically, the first hinge portion is the part of the lifting hinge that is typically fixed to a fixed structure (such as a wall or door frame), or optionally, fixed to a fixed glass component. The first hinge portion carries the support device and serves as a connector for the pivot assembly.

[0021] Specifically, the support device is a component arranged on the first hinge portion and has a vertical opening for supporting the pivot shaft assembly. The support device can be fixed in one or more planes and forms a base for rotatable support.

[0022] Specifically, the vertical opening is a through opening extending substantially in the vertical direction, used to accommodate the pivot assembly via a form-fit and / or force-fit connection. The vertical opening enables precise alignment of the pivot assembly, thereby allowing rotational and lifting movements along a predetermined axis.

[0023] Specifically, the pivot assembly is a substantially cylindrical or elongated component arranged between the first and second hinge portions and capable of rotational and lifting movements. The pivot assembly is characterized by a curved profile on each end face to induce a predetermined lifting action in conjunction with the bolt assembly. In other words, the pivot assembly has two end regions, each with a curved profile. Specifically, the pivot assembly has a bolt assembly guide head, which has a curved profile on one or both end faces. In particular, one or both bolt assembly guide heads are detachably mounted components of the pivot assembly, allowing for environmentally friendly replacement of individual components in case of wear, rather than replacing the entire hinge. Furthermore, by selecting an appropriate bolt assembly guide head, the curved profile can be adjusted as needed, thereby regulating the lifting behavior. This allows the lifting hinge to be reused and thus adapted to different conditions, such as varying substrate height or glass panel length, which is also environmentally beneficial. In particular, the pivot shaft assembly or any bolt assembly guide head, or two bolt assembly guide heads, can be designed as a hollow profile, a solid profile, or a hollow profile with end caps.

[0024] Specifically, the vertical support axis is the main rotation axis of the pivot assembly, which is vertically aligned. The second hinge portion rotates about this axis relative to the first hinge portion, while the additional elements generate lifting torque against the backdrop of the curved profile.

[0025] Specifically, the curved profile is a defined area on one or both end faces of the pivot assembly, preferably defined circumferentially, which is curved or wavy in at least one dimension. The curved profile is arranged at each end of the pivot assembly, interacts with the bolt assembly, and causes vertical movement during opening and closing.

[0026] Specifically, the bend peak is an elevated point or portion within a circumferentially extending bend profile, and the slope of the bend peak affects the upward movement of the bolt assembly. When the two hinge portions rotate toward each other, the bend peak serves to lift the bolt assembly. Furthermore, this region determines the maximum height the second hinge portion is lifted during the opening movement. Although the bend peak has both upward and downward slopes, in this context, the bend peak specifically refers to the portion of the bend profile that has an increasing slope starting from the zero position; that is, the portion of the bend profile that causes the upward movement of the second hinge portion.

[0027] Specifically, a bend groove is a recess or portion with a downward slope in a circumferential bend profile into which the bolt assembly moves when the two hinge portions rotate. The bend groove can, for example, define a stop position or a lower end position, thereby allowing the door to remain lowered in the closed position. Although the bend peak has both an upward and downward slope, in this document, a bend groove specifically refers to the portion of the bend profile that has a decreasing slope from the bend peak; that is, the portion of the bend profile that causes the second hinge portion to move downward.

[0028] Specifically, the second hinge portion is another element rotatably connected to the first hinge portion of the lifting hinge. The second hinge portion is U-shaped and is specifically designed for fixing or mounting glass door panels. It performs predetermined lifting and lowering during rotation.

[0029] Specifically, a U-shape is one construction for the second hinge portion, wherein the base extends from two parallel legs and forms a U-shaped profile. The legs are preferably parallel, but not necessarily. A U-shaped structure is also feasible, such as a V-shape with a dotted base. This U-shape provides space for the support device and pivot assembly between the legs, while the base ensures stability and connects the legs.

[0030] Specifically, the base is the connecting portion between the two legs of the second hinge portion. The second hinge portion can be attached to the glass door or to supplementary fastening components via the base and / or via the legs. The base may also feature structural reinforcement.

[0031] Specifically, the legs are two substantially parallel portions of the second hinge portion that laterally surround the support device and the pivot assembly. Optionally, the legs may be angled. The legs have horizontal and vertical leg recesses to accommodate the bolt assembly and the pivot assembly. The horizontal and vertical leg recesses are oriented such that their principal axes are specifically orthogonal to each other. In particular, the vertical leg recess is oriented relative to the vertical support axis, preferably parallel to or coaxial with it.

[0032] Specifically, the horizontal leg groove is a corresponding hole or milled groove in the leg that extends horizontally or is at least oriented primarily in the horizontal direction. A bolt assembly can be inserted into this groove so that the bolt assembly can contact the curved profile.

[0033] Specifically, the vertical leg groove is a corresponding hole or milled slot extending substantially vertically in the leg, through which the pivot assembly remains coaxial with the vertical support axis. This groove provides predetermined positioning and rotational guidance about the vertical support axis.

[0034] Specifically, a bolt assembly is a component that can be inserted into a horizontal leg recess and contacts a curved profile by its shape or position. A bolt assembly can be designed as a single-piece or multi-piece component, for example, designed to mate with screws, pins, or threaded pins, and guides movement along the curved profile during rotation.

[0035] Specifically, vertical offset is the vertical distance traveled by the second hinge section (and thus the glass door) between the closed and open states. Vertical offset is a direct result of the interaction between the bolt assembly and the bending profile, leading to the desired lifting or lowering.

[0036] Therefore, the interaction between the bolt assembly and the bending profile enables precise control of vertical offset during rotation, thus achieving the previously intended purpose. This allows for improved hinge functionality, particularly regarding automatic closing movement or improved sealing. Simultaneously, due to the interchangeable positioning of the bolt assembly, the same hinge type can be used for both DIN left and DIN right, significantly reducing inventory and production costs and allowing installers to easily convert settings in the field.

[0037] Therefore, a lifting hinge, particularly a flush-mounted revolving door lifting hinge, is proposed for supporting glass doors, especially frameless all-glass doors (such as shower doors). The lifting hinge is designed to have an integrated lifting mechanism and can be used as both a DIN left door hinge and a DIN right door hinge. This is achieved specifically through the symmetrical design of all necessary components, enabling left-to-right adjustability. In other words, the hinge can be easily switched on-site from one opening direction (e.g., to the left) to another (e.g., to the right) and vice versa, without any special additional components.

[0038] For example, lift hinges are designed as rotating door hinges, allowing the glass door to open in two directions: inwards and outwards. This provides advantages such as no water dripping onto the bathroom floor when the door is opened inwards, for example, in a shower room. The flush-mount design specifically ensures that no parts protrude into the shower area when the door is closed; the inside of the glass door and the fittings attached to it form a continuous, flat surface that can be easily cleaned, for example, using a scraper or similar tool. This produces an attractive appearance and prevents the formation of dirt edges.

[0039] Through the interaction of curved contours and bolt assemblies, the integrated lifting mechanism allows the door leaf to rise slightly when the door is opened and fall accordingly when the door is closed. In this way, when the door is closed, the door leaf can rest on the threshold or floor, with the seal attached to the bottom to ensure a high level of water tightness. When opened, the seal is released by the lifting action, which minimizes friction and wear on the seal and allows for a smooth opening.

[0040] Of course, the basic concept can be realized by arranging individual bolt assemblies in each horizontal leg recess, which are then secured in place as needed after the lifting hinge is properly positioned. However, it is preferable to reposition the individual bolt assemblies. In other words, it is important that the bolt assemblies engage with the curved profile to form the lifting mechanism.

[0041] This versatility saves storage space, reduces production and transportation costs, and makes on-site installation significantly more flexible.

[0042] When grooves are mentioned, they are generally understood as openings. These grooves, created through material removal, are not mandatory. It is possible for the part to have grooves directly created by casting, pressing, or other means; material removal is also feasible, particularly through machining.

[0043] The phrase "basically" means that the description following the phrase must be largely satisfied, but minor deviations are permissible. However, complete compliance with the description following the phrase "basically" is always preferred.

[0044] For example, when ordinal numbers such as "first," "second," etc., are used to specify components, elements, process steps, or process operations, these ordinal numbers are simply used to distinguish the intended purpose and do not indicate dependency or sequence. This in particular means that, for example, an apparatus does not need to have a "first component" in order to have a "second component."

[0045] The foregoing sections explained the advantageous aspects, and the following further describes preferred modified embodiments. In particular, the explanations of the advantages and definitions of the features are largely descriptive and preferred examples, but not limiting examples. If the explanation is limiting, it will be explicitly stated.

[0046] Optionally or additionally, it can be configured such that the first hinge portion, the pivot assembly, and / or the second hinge portion are formed substantially mirror-symmetrically with respect to the central horizontal plane of the lifting hinge. The mirror-symmetrical design of a single hinge portion or all hinge portions simplifies production because different parts are not required for the left and right sides. The symmetry also achieves an attractive appearance, as substantially identical parts can be used for both left-handed and right-handed versions. Furthermore, the symmetrical geometry increases ease of maintenance, as specific parts can be easily replaced or moved to the other side without requiring extensive adjustments. This facilitates cost-optimized mass production while reducing inventory.

[0047] Optionally or additionally, bolt assemblies are formed in multiple parts, particularly including screws and pins, or formed as a single-piece mating screw to achieve flexible installation. Bolt assemblies play a crucial role in transferring force from the bending profile to the second hinge section. The design of multiple parts (such as screws with pins) allows for fine adjustments to compensate for different component tolerances. Meanwhile, cost-effective single-piece assembly screw solutions are available if priority is given to particularly rapid assembly or lower production costs. Therefore, manufacturers can flexibly respond to different customer requirements, such as when particularly high load-bearing capacity or improved adjustment options are needed.

[0048] Optionally or additionally, the bend profile can be configured to include a waveform with varying bend peaks and / or bend groove slopes. The waveform design of the bend profile allows for individual adjustment of the lifting behavior based on specific requirements, such as door weight, desired closing characteristics, or sealing pressure. Different slopes in the bend peak or bend groove regions of the bend profile produce a segmented lifting effect. For example, this can allow for an initial moderate lift upon opening, followed by a more significant lift at further rotational positions. A locking effect can also be specifically achieved by changing the slope.

[0049] Optionally or additionally, the pivot assembly may be formed integrally or as a single piece, particularly as a single piece in a detachable manner. For example, integral pivot assemblies machined from a block of metal or manufactured by casting ensure high stability and dimensional accuracy because welds, screw connections, or adhesive joints can be eliminated. This reduces potential weaknesses and minimizes maintenance requirements. At the same time, single-piece manufacturing is cost-effective when producing in large quantities and has proven in practice to have excellent resistance to mechanical stresses, such as those that occur during frequent rotation of a glass door.

[0050] Optionally or additionally, the pivot assembly may include a shaft and, on each end face, bolt assembly guides disposed on the shaft, wherein each bolt assembly guide includes a curved profile on its end face. By forming bolt assembly guides with curved profiles on each end face of the pivot assembly, a symmetrical load distribution is achieved. This design is particularly suitable for larger or heavier glass doors because force absorption is distributed across two areas. Furthermore, the dual design of the curved profiles provides redundancy: if one side wears out, at least one essential function of the lifting mechanism remains intact. Additionally, fine adjustments to the door position can be achieved by positioning the bolt assemblies at different locations on the two bolt assembly guides.

[0051] Optionally or additionally, the curved profile may include at least one or more stop positions for the bolt assembly to hold the glass door in the closed position. Through one or more predetermined stop positions, the door can be reliably held in a specific position, particularly the closed position. This is advantageous for preventing accidental opening of the shower enclosure door. Optionally or additionally, a locking mechanism may be provided in the open position, for example, for cleaning purposes. The locking mechanism also reduces the force required to hold the door, thereby increasing user comfort.

[0052] Optionally or additionally, the bend profile includes at least two (particularly exactly two) bend peaks and at least two (particularly exactly two) bend grooves as a continuous waveform. A bend profile with exactly two bend peaks and two bend grooves provides a particularly compact design that still allows for different intermediate positions of the door. For example, the first bend peak can produce an initial lift during slight opening, while the second bend peak produces even greater lift at wider opening angles. The two defined bend grooves can represent separate stop positions. This simplifies the design and reduces production costs because complex multi-waveform profiles are not required.

[0053] Optionally or additionally, the curved profile can be configured to include an even number of curved peaks and an even number of curved grooves as a continuous waveform. An even number of curved peaks and grooves allows for a symmetrical design of the curved profile. This is particularly suitable for revolving doors because it unifies the behavior in both directions of rotation (inward and outward). As a result, the lifting hinge can exhibit similar lifting characteristics in both directions of rotation. Since the door can open with the same feel in either direction, this coordination brings great convenience to the user.

[0054] Optionally or additionally, the curved profile may include at least two radially opposite curved peaks and curved grooves. The radially opposite configuration of the curved profile provides a predetermined balance between the two directions of rotation. This is particularly useful when the door rotates in both directions, as the same mechanism applies when the door opens to the left or right. The symmetrical design also simplifies field installation because the profile exhibits the same lifting characteristics in all relevant locations. Furthermore, uniform wear is achieved because the load is distributed across two opposing areas. Moreover, the lifting hinge can be used in this manner, specifically as both a left-hand hinge and a right-hand hinge, without any difference in their rotational characteristics.

[0055] Optionally or additionally, the curved profile may include at least two or more radially opposing curved grooves to automatically hold the glass door in the closed position. If radially opposing curved grooves are included in the design, the door can be positioned in the closed position in both directions. Furthermore, this enables bidirectional rotation, where the door automatically returns to the closed position from both directions. This is highly desirable in shower applications, for example, to prevent the door from remaining open and to prevent leaks. Additionally, uniform wear is achieved because the load is distributed across two opposing areas. Moreover, the lift hinge can be specifically used in this way as both a left-hand and right-hand hinge, with no difference in its rotational characteristics.

[0056] Optionally or additionally, it may be provided that at least one bend (preferably several bends, most preferably all bends) includes a flat portion, particularly in the region of its apex, especially the flat portion of the bowl-shaped structure. The corresponding flat portions on the bends are specifically arranged at the highest point of the bend's slope, serving as a stop position and preferably reducing friction at the contact point between the bolt assembly and the bend profile, thereby facilitating a smooth transition between different stop positions or height positions. This not only protects the components involved but also has a positive impact on usability. This produces smooth engagement or disengagement, thus significantly reducing vibration or clicking noise.

[0057] Optionally or additionally, the lifting hinge may include at least one spring element and / or damping element in the area of ​​the pivot assembly or bolt assembly to assist or slow down opening and / or closing. By integrating the spring, the hinge can be additionally supported during opening because the spring stores energy and releases it again during closing. Conversely, the damping element (e.g., a hydraulic or pneumatic damper) prevents the door from slamming shut too quickly. These measures improve safety, especially when children or the elderly operate the door, and reduce mechanical stress. Despite these additional elements, low maintenance is maintained as long as the components are robustly designed for use in wet or humid environments (e.g., in a shower room).

[0058] Optionally or additionally, a second hinge portion may be designed to allow the glass door to rotate open from both sides, enabling it to rotate out of the closed position in both the first and opposite directions. This bidirectional rotation capability increases usability in rooms with limited space and enhances security, as the door can open in both directions in an emergency. This is particularly advantageous in hotel bathrooms, sauna areas, or accessible restrooms. The versatility of the hinge is further enhanced because single-sided opening does not require special hardware. Combined with the ability to use the hinge on either the left or right side, this results in a flexible solution adaptable to various installation configurations.

[0059] Optionally or additionally, it may be provided that at least one or more stop devices are provided, which restrict the rotation of the second hinge portion in at least one or two rotational directions. The stop devices ensure that the door does not open beyond a certain angle to prevent collision with walls, furniture, or other components. This is especially important in the case of a tight installation. Such stop devices can be mechanical, such as pins engaged in a cut, or integrated into a curved profile.

[0060] Optionally or additionally, the second hinge portion and the first hinge portion may be configured such that, in the closed position, they are substantially flush with the adjacent surface. The closed position refers to the zero position of the lifting hinge. This flush design aligns with trends in modern architecture and bathroom fixtures because it is aesthetically pleasing and offers hygienic advantages (easier cleaning). Furthermore, it eliminates the potential for dirt or scale buildup on protruding edges. This design requires precise coordination of hinge geometry, but this is achieved through the described lifting technology.

[0061] Optionally or additionally, the adjustment device can be configured to readjust the position of the second hinge portion relative to the first hinge portion in the lateral or vertical support axis direction. This ability to adjust at a later stage extends the overall system lifespan and allows for compensation for tolerances in the installation environment. If building settlement or door warping occurs, installers can use screws, eccentric bolts, or other mechanisms to correct the position of the second hinge portion. This allows for the permanent maintenance of the closed profile and increases operational reliability (particularly sealing and secure closure contact). This is a significant competitive advantage because it reduces problems caused by warped doors or blockages.

[0062] Optionally or additionally, the pivot assembly is essentially dumbbell-shaped, comprising two end-face bolt assembly guide heads and a narrower shaft portion located between them. The dumbbell-shaped design of the pivot assembly ensures efficient force transmission because the wider area on the end faces (i.e., the guide heads) serves as the contact area for the bolt assemblies, while the narrower central portion allows for a degree of freedom of movement for rotation and lifting. This design increases stability and reduces the risk of bending stress at the center. Furthermore, installation is simple because the bolt assemblies can be fitted over or through the outer heads, while the central shaft portion can be easily inserted into a vertical opening. Here, the advantage of a universal orientation also becomes apparent: the dumbbell geometry can be used on either the left or right side without any problems.

[0063] Optionally or additionally, it may be configured such that the lifting hinge, in its operational state—that is, after the lifting hinge has been installed, or in other words, after its assembled state—includes exactly one bolt assembly in the upper horizontal leg recess. In this case, the lifting hinge, in its assembled state, also includes another bolt assembly in the other horizontal leg recess, which prevents vertical offset between the first and second hinge portions during or before installation is completed. For this purpose, in the assembled state of the lifting hinge, its components (particularly the two bolt assemblies) are arranged in the horizontal leg recesses such that they are each positioned in a curved groove of a curved profile associated with them. In particular, the operational state refers to the state in which the lifting hinge (e.g., while supporting a glass panel) is in routine operation. The assembled state is defined as the state before the lifting hinge is secured (particularly tightened) to its final base using its first hinge portion. Specifically, the lifting hinge transitions from the assembled state to the operational state after the first hinge portion has been secured to its final base (particularly by screws), and / or after the lower bolt assembly has been removed from the lower horizontal leg recess. Therefore, the lower bolt assembly loses its locking function due to the fact that, without this other bolt assembly, the first hinge portion must be held stably during installation. Thus, without this lower bolt assembly, according to the exemplary embodiment, the hinge portion must first be aligned with its position on the panel body to be installed (particularly designed for glass doors) and tightened. Then, the panel body is moved to the desired position and aligned, particularly using a level and / or glass blocks. Finally, the locations of the drilled holes for the first hinge portion are marked. The problem here is that, without this design, the first hinge portion must actively remain in place. After marking the drilled holes, the panel body is repositioned, drilled, and then the panel body can be installed. It is conceivable that alternative fastening methods such as welding could be used instead of drilling.

[0064] Specifically, when the lifting hinge is delivered, both bolt assemblies are installed or at least included for installation. The bolt assemblies lock the lifting mechanism, preventing the lifting hinge from moving up and down, or allowing only minimal movement; this is relative to the first hinge portion. Therefore, it is not determined whether the lifting hinge is designed for DIN right or DIN left. This allows the installer to install the lifting hinge as if it had no lifting function. Once the installer removes the lower bolt assembly, specifically by loosening it, the obstruction to the lifting function is removed, and the lifting hinge functions as described in the remainder of this disclosure, particularly adjustable to DIN right or DIN left depending on the installation position. In other words, regardless of whether the lifting hinge is for a DIN right or DIN left configuration, the lower bolt assembly must be removed to transition from the assembled state to the operational state. As a result, the installer can more easily attach the lifting hinge to the base, particularly by tightening it, because the first hinge portion (particularly designed as a mounting plate) is positioned in a non-raised / vertically offset position.

[0065] The listed features enable a wide variety of configurations that allow the proposed lifting hinge to be better adapted to different installation and application scenarios. In particular, combinable features such as symmetrical design, bolt assemblies formed as a single piece or in multiple parts, wavy bend profiles, and / or integrated spring elements or stop devices result in high flexibility and low maintenance requirements. Since these features support left-to-right conversion without major modifications, they bring significant cost savings and logistical advantages to manufacturers and users. The design of the bend shape, such as an even number of bend peaks, radially opposite bend peaks, and bend grooves, further contributes to a versatile and advantageous mechanism that experiences minimal wear, is easy to install, and provides high ease of use.

[0066] Furthermore, the embodiments involve a pivot shaft assembly, a bolt assembly, a first hinge portion, and a second hinge portion for the aforementioned lifting hinge. Attached Figure Description

Detailed Implementation

[0069] The described embodiments are merely examples that may be modified and / or supplemented in various ways within the scope of the claims. Any feature described with respect to a particular embodiment may be used independently or in combination with other features in any other embodiment. Any feature described with respect to a particular class of embodiments may also be used accordingly in embodiments of another class. Any graphical differences between the drawings shown are attributable to symbolic characteristics of the patent drawings. Where feasible, the graphical disclosure of the various features will be understood as a specific technical configuration of the component. All Figures 1 to 15 The lift-and-lower hinge will be assigned to a single embodiment, wherein... Figure 7 and Figure 8 The only difference between them is the bolt assembly.

[0070] Figures 1 to 11A lifting hinge 10 is shown, configured to support a glass door. The lifting hinge 10 includes at least one first hinge portion 12, on which a support device 14 is arranged. The support device 14 includes a continuous vertical opening 14a for supporting a pivot assembly 16. The pivot assembly 16, having a vertical support axis 16a, rotatably connects the first hinge portion 12 to a second hinge portion 18. The pivot assembly 16 includes a curved profile 17 on each end face, having at least one curve crest 17.1 and at least one curve trough 17.2. The second hinge portion 18 has a U-shaped form with a base 20 and two legs 22 and 24, and is rotatably connected to the support device 14, at least indirectly, via the pivot assembly 16. Each leg 22, 24 includes corresponding horizontal leg recesses 22a, 24a and corresponding vertical leg recesses 22b, 24b. The horizontal leg recesses 22a, 24a are configured to support the bolt assembly 26 (which may be referred to as the "first bolt assembly 26"), and the vertical leg recesses 22b, 24b are configured to support the pivot assembly 16. The pivot assembly 16, the vertical support axis 16a, and the two vertical leg recesses 22b, 24b are coaxial with each other. Furthermore, the bolt assembly 26 is provided, configured to selectively insert into one of the two horizontal leg recesses 22a, 24a, to interact with the curved profile 17 of the pivot assembly 16 when inserted into one of the two horizontal leg recesses 22a, 24a, such that the second hinge portion 18 rotates relative to the first hinge portion 12 while simultaneously undergoing a vertical offset relative to the first hinge portion 12.

[0071] As shown in the figure, the first hinge portion 12, the pivot assembly 16, and / or the second hinge portion 18 may be constructed in a mirror-symmetrical manner with respect to the central horizontal plane 10a. In this case, the bolt assembly 26 may be designed as a single-piece mating screw or multiple components (e.g., designed as a screw and pin), see details below. Figure 7 This is to meet various installation and maintenance requirements. Furthermore, in a preferred embodiment, the bending profile 17 of the pivot shaft assembly 16 has a wave-like shape with at least two bending peaks 17.1 and at least two bending grooves 17.2 to produce a predetermined lifting motion.

[0072] exist Figure 8 As can be seen, the pivot assembly 16 can be manufactured integrally, and if desired, has bolt assembly guides 30.1 and 30.2 on each end face, with a narrower shaft portion 28 located between the bolt assembly guides 30.1 and 30.2. This allows force to be evenly distributed to the two legs 22, 24. Although not shown in detail, spring elements or damping elements may be provided in the areas of the pivot assembly 16 or bolt assembly 26 to assist or slow down the closing process.

[0073] As can be inferred from the figure, the second hinge portion 18 can be rotated open on both sides, allowing the glass door to open inwards and outwards. A stop device (not shown) can restrict rotation in one or both directions. In the closed position, the glass door can be flush with the adjacent surface, achieving a low-profile aesthetic. For precise alignment during installation, an adjustment device can be provided, which allows adjustment in the lateral direction or along the vertical support axis 16a.

[0074] If the lifting hinge 10 is DIN left, see Figure 1 and Figure 2 Then, the second hinge portion 18 can be rotated or moved toward the first hinge portion 12 to such an extent that the bolt assembly 26 located in the horizontal leg groove 22a of the initial upper leg portion 22 is exposed, and as... Figure 3 As shown, the second hinge portion 18 is removed. Then, the lifting hinge 10 can rotate about the central horizontal plane 10a, specifically by 180 degrees, so that the original upper leg portion 22 now becomes the lower leg portion, and the original lower leg portion 24 now becomes the upper leg portion. Figure 4 The rotating lifting hinge 10 is shown, wherein the bolt assembly 26 is inserted into the horizontal leg recess 24a of the initial lower leg 24, which is now the upper leg. In doing so, the bolt assembly 26 is inserted until it engages with the bolt assembly guides 30.1, 30.2 of the pivot assembly 16; see, for example, [reference needed]. Figures 7 to 11 Various views. From this point onward, the lifting hinge 10 is DIN right, for example, as... Figure 5 and Figure 6 As shown in the diagram. Similarly, the lifting hinge 10 can also be switched from DIN right to DIN left.

[0075] Figure 12 The bolt assembly guides 30.1 and 30.2 of the pivot shaft assembly 16 are shown, each bolt assembly guide having a curved profile 17 disposed on its end face. The curved profile 17 includes two curved peaks 17.1 and two curved grooves 17.2. Specifically, the two curved peaks 17.1 and the two curved grooves 17.2 are arranged radially opposite each other, and particularly arranged in a uniform wavy pattern relative to each other. Each of the two curved peaks 17.1 has a flat portion 29.

[0076] Figure 13 It shows that according to Figure 12 The bolt assembly guide heads 30.1 and 30.2 have bolt assemblies 26, which are located in two radially opposite curved grooves 17.2. As a result, the lifting hinge 10 is in a stopped or stationary position.

[0077] Figure 14 Bolt assembly guide heads 30.1 and 30.2 are shown, wherein, as Figure 13 The bolt assembly 26 shown is in a further rotated position, wherein the bolt assembly 26 is located in two radially opposite bending peaks 17.1. The bolt assembly 26 is located on two flat portions 29 of the bending peaks 17.1. As a result, the lifting hinge 10 is in a stopped or stationary position.

[0078] Figure 15 A pivot shaft assembly 16 arranged in the support device 14 is shown.

[0079] Figures 16 to 18 The lifting hinge 10 is shown in its assembled state (i.e., before final assembly or before its operational state). In this case, Figure 17 The embodiment of the lifting hinge 10 shown corresponds to, for example... Figure 9 The bolt assembly shown is constructed in a similar design to the latter, or combined with the latter. All lifting hinges 10 are designed such that they have at least one bolt assembly 26 in the upper horizontal leg recess 22a, wherein… Figure 17 The lifting hinge 10 shown has only one bolt assembly 26 in the upper horizontal leg recess 22a. Conversely, in Figure 16 It can be seen directly from and through Figure 18 As can be seen from the technical effect, the lifting hinge 10, in its assembled state, also includes another bolt assembly 26a (which may be referred to as "second bolt assembly 26") in another horizontal leg groove 24a, wherein the two bolt assemblies 26, 26a are respectively arranged in the horizontal leg grooves 22a, 24a, such that the two bolt assemblies 26, 26a are each positioned in the bending groove 17.2 of the bending profile 17 associated with them.

[0080] Figure 17 The vertical offset between the first hinge portion 12 and the second hinge portion 18 is shown. This vertical offset must typically be compensated for during assembly by actively holding the first hinge portion 12 during installation.

[0081] In other words, as Figure 17 Variations, Figure 16 and Figure 18 The diagram shows that, in addition to the upper bolt assembly 26 required for the lifting function, a lower bolt assembly 26a is also screwed in, which facilitates assembly. This prevents the first hinge portion 12 from falling vertically or shifting vertically, because the first hinge portion 12 is held in a predetermined position by the lower bolt assembly 26a.

[0082] Once assembled, the other bolt assembly 26a at the bottom can be removed from the lower horizontal leg recess 24a, allowing the lifting hinge 10 to transition from its assembled state to its operational state. This can occur regardless of whether the lifting hinge 10 is DIN left or DIN right.
