Description

Technical Field

[0001] Embodiments of the present invention generally relate to door closing systems. In particular, the present disclosure relates to a hinge device that provides stability, user-centric control, and overall enhancement of door operation.

[0002] Background Art of the Present Invention

[0003] Doors and cabinets are common components of daily infrastructure and are traditionally operated using basic hinge systems. Although these hinge systems are based on pivoting motion, they generally fail to provide a refined user experience. Common problems include door sagging, misalignment after frequent use, or an inability to close gently, causing significant disruption.

[0004] In addition, with evolving architectural designs and growing consumer demands for enhanced user-centric control, traditional hinge systems quickly become obsolete. Although they are successful in their primary functions, they lack finesse, precision, stability, and adaptive control. Such inherent limitations result in inefficient operation, requirements for regular maintenance, and potential wear over time.

[0005] Hinge technology has also traditionally faced problems such as sudden door closing, inconsistent gaps between the door and its frame, and even annoying squeaking, indicating friction between components that requires lubrication.

[0006] Recently, innovative attempts have been made to integrate features such as soft-close dampers, which, although effective, have limited ability to provide an overall solution. Additionally, while some modern hinge systems do incorporate self-lubricating mechanisms to reduce maintenance intervals and ensure smoother operation, they lack adaptability to changing usage patterns.

[0007] Furthermore, traditional hinge designs also lack a modular architecture, making upgrades or component replacements a challenging task. Thus, if a part of the hinge system fails or requires an upgrade, the entire hinge device typically has to be replaced.

[0008] Therefore, there is still a need in the art for a hinge device system that can overcome the above problems and also integrate enhanced features such as user-centric control, adaptive lubrication, modular components, and a safety mechanism to prevent jamming or pinching.

[0038] The present invention aims to revolutionize the traditional door hinge system and address common challenges such as misalignment or sagging of the door relative to the base, sudden closing, and maintenance issues. The hinge device in the present invention is configured to enhance stability, user-centered control, and improved door operation.

[0039] Figure 1A shows a hinge device according to an embodiment of the present invention. As Figure 1A shown, the hinge device (100) includes but is not limited to a main hinge base (102), a hinge arm (106), a hinge cup (107), one or more adjustment screws (104a, 104b), and a hinge connecting piece (103a) having a hinge pin and a door clearance stabilizing member (106).

[0040] One end of the main hinge base (102) of the hinge device (100) is operably connected to a support base (such as a door frame, a cabinet frame, etc.), and the other end is connected to a door through a hinge cup (107). In addition, the hinge cup (107) is attached to the door (202) through a door connecting bracket or a door clearance stabilizing member (106) at the opposite end. Herein, the main hinge base (102), the hinge cup (107), and the door clearance stabilizing member (106) are connected by one or more connecting members (104). The material selected for the main hinge base (102) can be but is not limited to stainless steel, zirconium, Monel alloy, bronze, Inconel alloy, aluminum alloy, nickel, and nickel alloys.

[0042] The hinge pin can be understood as a strong metal cylindrical rod configured to be able to rotate the hinge cup (107). The door clearance stabilizing member (106) includes one or more adjustment screws (104a - 104b) and is configured to be able to adjust the in - out and left - right movement of the door. In some embodiments, the main hinge base (102) and the hinge cup (107) can be equipped with a universal mounting plate (not shown) to facilitate installation on various surfaces. The material selected for the hinge cup (107) and the hinge pin can be but is not limited to stainless steel, zirconium, Monel alloy, bronze, Inconel alloy, aluminum alloy, nickel, and nickel alloys. This ensures durability and corrosion resistance.

[0043] Figure 1B Shows an exploded view of a hinge device with a door clearance stabilizing member according to an embodiment of the present invention. Figure 1BA more detailed view showing the components of the hinge device (100) is presented. The hinge arm (106) includes an upper hinge arm (106a) having an orientation pin (1040a), a middle hinge arm (106b) having one or more orientation guide grooves (1040b), and a lower hinge arm (106c). The material selected for the hinge arm (106) can be, but is not limited to, stainless steel, zirconium, Monel alloy, bronze, brass Inconel alloy, aluminum alloy, nickel, and nickel alloys. This ensures durability and corrosion resistance.

[0044] One or more adjustment screws (104a, 104b) include one or more left - right adjustment screws (104a) and in - out adjustment screws (104b). The one or more adjustment screws (104a, 104b) are configured to enable left - right and in - out adjustment of the door (202) relative to the support base (1010). Additionally, one or more orientation pins (1040a) are configured to be within one or more orientation guide grooves (1040b) and are adjusted to guide the upper hinge arm (1060a), as Figure 2A and 2B shown.

[0045] The hinge pin (103) can be placed between the hinge cup (107) and the door clearance stabilizing member (106) with a spring or a reset mechanism. The spring or reset mechanism not only ensures a controlled return to the initial posture but also can resist unnecessary movement, thus providing functions such as "soft closing" or "soft opening" of the door, preventing sudden movements and facilitating smooth operation.

[0046] The hinge pin (103) can be covered by a hinge pin cover. The material used for the hinge pin (103) can be, but is not limited to, selected from nylon, bronze, brass, Teflon, stainless steel, or aluminum to reduce friction, reduce wear, and hold the hinge firmly in place.

[0047] Furthermore, the hinge device (100) also includes a door opening angle controller (108), an adjustment button (108b) having one or more adjustment punching paths (108a), an opening angle limiter (108c), and a suspension system. Among them, the suspension system includes a hydraulic piston (111a) and a hydraulic piston connection part (111b) located below the lower hinge arm (106c).

[0048] Figures 2A - 2B An adjustment screw arrangement for uniform clearance in the door clearance stabilizing member according to an embodiment of the present invention is shown. As Figures 2A - 2BAs shown, one end of the hinge device (100) is firmly anchored to the base platform or support base (1010) via the hinge base (102), and the hinge cup (107) is attached to the door (202) by a door connection bracket or door gap stabilizing member (106) at the opposite end. The connection between the hinge base (102) and the door gap stabilizing member (106) is established through the integration of the lower hinge arm (106c) with the hinge base (102).

[0049] As Figure 2A shown, one or more alignment pins (1040a) may be configured to be movable from left to right or up or down within the alignment guide slots (1040b). The movement of one or more alignment pins (1040a) may result in increasing or restricting the left - to - right movement range of the door or flap door (202) relative to the frame or cabinet (1010). Similarly as Figure 2B shown for the hinge device (100), one or more alignment pins (1040a) may be configured to be movable from left to right or up or down within the alignment guide slots (1040b). The movement of one or more alignment pins (1040a) may result in increasing or restricting the in - and - out movement range of the door or flap door (202) relative to the frame or cabinet (1010).

[0050] The base platform or support base (1010) may be, but is not limited to, selected from doors, frames, etc. Herein, the door (202) at the hinge cup (107) may be understood as a flap door, or a frame - supported glass, or a surface movable about the hinge pin (103).

[0051] Figure 3A Shown is a door opening angle controller of the hinge device according to the present invention. As Figure 3A shown, the hinge device (100) includes a door opening angle controller (108) operably connected to the hinge cup (107), and a door connection bracket or door gap stabilizing member (106).

[0052] Figure 3B Shown is a side view of the door opening angle controller according to the present invention. As Figure 3B shown, the door opening angle controller (108) includes an opening angle limiter (108c) and an adjustment button (108b) having a punching adjustment path (108a).

[0053] Figures 4A - 4C Shown is the operation of the door opening angle controller operating at a predetermined angle according to the present invention. As Figures 4A - 4CAs shown, the door opening angle controller (108) can be adjusted to a predetermined angle or a predetermined range, which is selected from but not limited to the range of 80 degrees to 120 degrees. In the opening angle control, the adjustment button (108b) is adapted to slide into the adjustment path (108a), and thus, the sliding movement is controlled within the adjustment path (108a). It can control or limit the opening angle of the door. The hydraulic piston connection part (111b) is configured to be able to supplement the function of the opening angle limiter (108c). The door opening angle controller (108) is adapted to control the opening or closing angle of the door (202) within a predetermined range.

[0054] In some embodiments, the door opening angle controller (108) can be adjusted to one or more different positions, such as Figures 4A - 4C illustrated in embodiments (410 - 430), where the predetermined angles are set to 85 degrees, 95 degrees, and 105 degrees. In Figure 4A this case, the door opening angle controller (108) is configured for angular movement ranging from 0 to 105 degrees between the door (202) and the support base (1010) (referred to as setting 1).

[0055] In Figure 4B this case, the door opening angle controller (108) is configured for angular movement ranging from 0 to 95 degrees between the door (202) and the support base (1010) (referred to as setting 2). In Figure 4C this case, the door opening angle controller (108) is configured for angular movement ranging from 0 to 85 degrees between the door (202) and the support base (1010) (referred to as setting 3). For user convenience and safety, it ensures a consistent and controlled door opening angle. In some embodiments, the door opening angle controller (108) can act as a protection mechanism to minimize overextension that may cause obstruction or damage. The door opening angle controller (108) is not only a static component but also an adjustable locking mechanism that allows the user to specify different door angles according to individual preferences.

[0056] The material selected for the hinge device (100) can be but not limited to stainless steel, zirconium, Monel alloy, bronze, brass, Inconel alloy, aluminum alloy, nickel, and nickel alloys. It ensures durability and corrosion resistance.

[0057] To understand the operating method (100) of the present invention, consider the exemplary embodiments shown in FIGS. 1 and Figures 2A - 2B as shown. The hinge device (100) is configured to facilitate the rotation of an object such as a door or window frame (202) around a predetermined axis along the hinge pin (103) near a wall or support base (1010). In as Figures 2A - 2BDuring the opening or closing movement shown, the door (202) can be controlled by the rotational movement of a hinge pin (103) placed within a protective sleeve-like structure between the hinge cup (107) and the door clearance stabilizing member (106), ensuring a gentle swing of the door, cabinet, or window (202). The door clearance stabilizing member (106) integrated on the main hinge base (102) uses an adjustment screw (104) to maintain a consistent clearance between the support base (1010) and its frame or cabinet (202), as Figure 2A (normal position) and Figure 2B (with clearance) shown. In the up and down connection, the hinge device (100) remains vertically aligned, while in the left and right connection, it ensures the horizontal stability of the door (202). The door clearance stabilizing member (106) is configured to perform left and right adjustment and simultaneous in and out adjustment in response to the left and right adjustment of the door (202) relative to the support base (1010), ensuring a uniform clearance between the door (202) and its support base (1010). This method can reduce the need for regular maintenance and increase the lifespan of the door hinge device system.

[0058] In some embodiments of the present invention, the hinge device (100) may be adapted to accommodate one or more soft-close dampers (not shown), which can avoid additional suspension to achieve smooth or soft opening and closing of the door (202). A soft-close damper is a component configured to ensure smooth and quiet closing of a door or drawer (202). It includes a robust housing and a piston that operates using a viscous liquid or a spring mechanism. When the door (202) closes, the piston moves to create resistance by pushing the viscous liquid or through spring tension, ensuring smooth and quiet closing. The material of the housing can be, but is not limited to, selected from polycarbonate (PC), polyoxymethylene (POM) or acetal, aluminum, stainless steel, zinc alloy, or ABS (acrylonitrile butadiene styrene). While the material of the piston can be, but is not limited to, selected from polyurethane (PU), polyethylene (PE), PTFE (polytetrafluoroethylene or Teflon), brass, anodized aluminum, or stainless steel.

[0059] In some embodiments of the present invention, the hinge device (100) may be adapted to accommodate a self-lubricating unit (not shown). It automatically distributes lubrication according to the usage pattern. The self-lubricating unit includes a container for lubricant storage, which can vary in shape according to its application. A porous medium, such as sintered bronze or a porous polymer, allows the gradual flow of lubricant or viscous liquid. The porous material has interconnected pores that function similarly to capillaries, facilitating lubricant distribution through capillary action. The lubricant is selected from substances such as, but not limited to, oil or grease, reducing friction between components. One or more seals or "O" - rings can be used to ensure the containment of the lubricant and protection from contaminants. Optionally, a spring can be used to further regulate the release of the lubricant. This self-lubrication ensures consistent and smooth operation of the hinge and long-term use, reducing the need for maintenance.

[0060] The hinge device (100) forms a pivot bridge between the entrance door (202) and the doorframe (1010). Acting as an intermediary, it allows the door to swing open or closed slowly while remaining firmly anchored to the frame. On the other hand, the doorframe, usually made of a similar material, provides the basic structural support. Embedded within this hinge device is an ingenious door opening angle controller (108), which plays a crucial role in indicating the movement of the door. Made of a durable metal such as stainless steel or aluminum, this component ensures that the swing angle of the door remains flexible between 80 and 120 degrees. A necessary part of the door opening angle controller (108) is the adjustment button (108b), possibly refined from durable plastic or aluminum, which allows the user to easily modify the swing angle of the door. The adjustment button (108b) moves along a path called the adjustment punch path (108a). These paths are usually made of a sturdy metal such as stainless steel or brass as they need to be precise and long-lasting. The opening angle limiter (108c) and the hydraulic piston connection part (111b) work together to prevent potential overextension of the door. The limiter, made of a sturdy metal such as steel or aluminum, sets a protective boundary, while the hydraulic piston, constructed from a pressure-resistant material such as stainless steel, ensures that the movement of the door remains smooth and consistent. Overall, the careful design and synchronization of each component within the hinge device not only enhance functionality but also improve user convenience, safety, and the overall aesthetic of the space.

[0061] For example, if a user decides to renovate their kitchen, they would like their kitchen cabinet doors to operate smoothly, with even gaps, a soft-close mechanism, and an adjustable door opening angle. To meet these requirements, the hinge device (100) of the present invention can be used. The installation can start by attaching the main hinge base (102) to the cabinet frame. Then the hinge cup (107) can be connected to the door via the door gap stabilizing component (106). These components can be connected using one or more connecting elements such as screws (1040). For easy future adjustment, adjustment screws (104a, 104b) are incorporated.

[0062] After installing the door, a slight misalignment in the gap may be noticed. The misalignment can be corrected by turning the adjustment screw (104a) and the alignment pin (1040a) within the alignment guide slot (1040b), ensuring that the door-cabinet gap is perfectly consistent. To enhance the user experience and prevent the door from closing suddenly, a soft-close damper with a suspension system can be integrated. The damper can ensure that the door closes smoothly and quietly. The user's preference for a maximum door opening angle of 95 degrees can be achieved through the door opening angle controller (108). The setting can be achieved by using the opening angle limiter and the adjustment button.

[0063] The hinge device also has a self-lubricating unit, ensuring lasting smooth operation without the need for manual lubrication. During testing, users found that the door maintained an attractive consistent gap with the cabinet. The soft-close damper ensures a gentle and quiet closing even when closing quickly. The movement of the door is restricted beyond its desired 95 degrees, and within a few days, due to the self-lubricating mechanism, its operation remains seamless and without wear or noise. Overall, users are fully satisfied with the performance of the hinge device and consider it an important part of the success of their kitchen renovation.

[0064] Similarly, if the user decides to upgrade the entrance door for enhanced functionality and aesthetics. The user selects an innovative hinge device (100) to connect the entrance door (202) to the doorframe (1010). Once installed, the alignment of the entrance door (202) with the doorframe (1010) is significantly improved. When the door swings open, it reveals one of the most remarkable features of the hinge device: the door opening angle controller (108). Attached Figures 4A - 4C The device detailed therein allows the opening angle of the door to be precisely adjusted. A range is provided to the user, particularly between 80 and 120 degrees, to define the extent of the door's swing.

[0065] When the user desires a wider entrance, they adjust the door opening angle controller (108) to achieve an angular movement of up to 105 degrees between the entrance door (202) and the doorframe (1010), as Figure 4A shown. However, when space constraints require a narrower swing, the angle is reduced to 95 degrees, as Figure 4B shown. For tighter spaces or to prevent potential collisions with adjacent walls, the angle is set to a more restricted 85 degrees, as Figure 4C shown.

[0066] The advanced design of the hinge device provides a consistent and controlled door opening angle, meeting the requirements of safety and convenience. Additionally, the door opening angle controller (108) serves as a protective measure, ensuring that the door does not overextend and preventing obstruction or damage. Due to the ability to lock the angle of the door according to individual preferences, users feel an enhanced sense of control over their living space, making the hinge device (100) a valuable addition to their apartment entrance.

[0067] Consider the scenario where the user has a double-door system, where each door is hinged on opposite sides of a common frame. In this case, the hinge device is placed between the two doors such that they can move independently but with synchronous precision. Each door is equipped with its own main hinge base (102), which is attached to the support base (1010).

[0068] When the user approaches to open the first door, the main hinge base (102) on the door engages and pivots smoothly. Since the main hinge base (102) is attached to the support base (1010), the movement of the door is controlled and smooth. The hydraulic piston connection (111) ensures that the door does not close suddenly or swing too fast. The hydraulic piston connection part (111b) serves to enhance the function of the opening angle limiter (108c).

[0069] Now, when the user advances to the second door, the process is repeated. The main hinge base (102) on the second door engages and swings open with the same controlled movement as the first door because it is attached to the support base (1010). The door opening angle controllers (108) on both doors ensure that they open to a predetermined angle set by the user according to the user's preference, and this predetermined angle can be any angle from 80 degrees to 120 degrees.

[0070] This double-door system with hinge devices provides the user with the flexibility to open one or both doors. The door opening angle controller (108) ensures safety by preventing any accidental large swings, which can be dangerous in confined spaces or where there are obstacles. As can be seen from the above description, the hinge device (100) of the present invention effectively solves several key objectives crucial for modern door installations. Stability is emphasized in some embodiments, and other durable materials can also be used in its device, including but not limited to features such as adjustable locking mechanisms, thus ensuring reliable door operation and precise control.
