Abstract
Description
Technical Field
[0001] This invention relates to a hinge for a door or window, comprising a frame hinge component having a mounting section and a generally cylindrical receiving sleeve mounted on a fixed frame, a sash hinge component having a mounting section and a hinge stop plate mounted on a door or window sash, and a shaft element that is hingedly connected when the two hinge components are stacked vertically in the installed state. The shaft element has a pin section into which the receiving sleeve can be inserted and a receiving section at one end for accommodating the hinge stop plate. The hinge stop plate is adjustable in the receiving section of the shaft element via an adjustment device, and can be adjusted vertically along the longitudinal axis of the shaft element. Background Technology
[0002] Roller-type door hinges consist of a frame hinge component and a leaf hinge component, each with a mounting section and a section connected to the shaft element. The mounting section can be bolted to the door frame and door leaf from within the door frame, so only the shaft element and its receiving section are visible from the outside as the so-called "roller" portion. It is worth noting that the terms "frame hinge component" and "leaf hinge component" do not necessarily refer only to the installation state where the frame hinge component is mounted on the door frame and the leaf hinge component is mounted on the door leaf. Depending on the application, the installation directions of these two components can also be opposite, or they can also be used as hinges connecting two doors in a multi-leaf or split-type door system.
[0003] For precise adjustment of the door leaf position relative to the door frame, it is best to install an adjustment mechanism inside the door hinge. The simplest approach is to place the adjusting bolts for adjusting the door leaf position relative to the door frame in the mounting section of either the leaf or frame hinge assembly. The disadvantage of this approach is that adjustments can only be made when the door is open, and the position must be checked when the door is closed. Furthermore, installing the adjustment mechanism in the mounting section increases space requirements, necessitating the creation of corresponding recesses within the door frame, thus increasing the manufacturing cost of these components. Depending on the specific application, this method may not be feasible.
[0004] In some implementations, the adjustment mechanism is located in the shaft element area. The advantage of this is that the adjustment mechanism can be operated even when the door is closed. However, this often results in axial misalignment between the sash hinge components and the frame hinge components, and also produces an unsightly appearance. The increased complexity of the shaft element area also frequently leads to a lack of stability in the pivot structure, resulting in gaps during use and requiring frequent readjustment of the door position.
[0005] Patent WO 00 / 66863A discloses a roller-type hinge in which axial positional deviations between the frame and sash hinge components during fine adjustments are masked by a sleeve that is aligned with and connected to either the frame or sash hinge component. For this structure to function properly, the cross-section of the corresponding hinge component within the sleeve needs to be reduced to accommodate the adjustment range of the axial positional deviation. This reduction in cross-section weakens the force transmission performance of the components in that area, and the final adjustment relies solely on the adjusting device itself for fixation. Therefore, it is impossible to prevent changes over time; it is precisely due to increased load in this area that the door sash may shift over time, or gaps may appear within the hinge.
[0006] Patent EP 2186980 A discloses a highly similar hinge, which is adjusted by leaving a certain axial gap within the receiving section of the hinge stop. It also relies solely on an adjustment device to fix the final position, thus suffering the same problems mentioned above. Summary of the Invention
[0007] Therefore, the object of this invention is to improve the aforementioned hinge by incorporating an adjustment function within the "roller" portion of the hinge, preventing externally visible axial positional deviation between the fan hinge component and the frame hinge component, and enhancing the hinge's stability to prevent spontaneous displacement or gap formation. Stability between the fan hinge component and the frame hinge component, as well as optimized force transmission, should be achieved in the simplest possible way, thereby reducing the production cost of such a hinge.
[0008] This invention achieves the above objective by providing at least one clamping block within the receiving section for the hinge stop, preferably two clamping blocks. Each clamping block is connected to the shaft element via a respective connecting element. Each clamping block has a transverse cut perpendicular to the longitudinal axis of the shaft element, which is respectively embedded in a corresponding symmetrical transverse groove on the hinge stop. Each clamping block moves between a clamped position and a released position via the connecting element. By providing clamping blocks, a stable, gapless connection is established between the hinge stop and the shaft element, thus eliminating the need to transmit force solely through an adjustment device. To adjust the hinge, the clamping block is moved to the released position to allow the hinge stop to be adjusted within the receiving section via the adjustment device. After adjustment, the clamping block is moved back to the clamped position to prevent further adjustment.
[0009] According to a preferred embodiment of the present invention, the width of the shaft element receiving section in the direction perpendicular to the longitudinal axis of the shaft element is greater than the width of the hinge stop, so as to allow for a lateral adjustment distance for the hinge stop. The adjustment device is an adjusting bolt disposed in a threaded hole on the hinge stop, the adjusting bolt passing through the width of the receiving section and fixed within the receiving section. With this preferred embodiment, the structure of the shaft element can be made more stable and can withstand greater forces.
[0010] As another preferred feature, the width of the clamping block is the same as the width of the receiving section, wherein the clamping bolt serves as a connecting element, fixing the clamping block to the bottom of the receiving section and connecting it to the shaft element. The clamping block with the transverse cut can also guide the adjustment direction of the hinge stop when in the loosened position, because the transverse cut and the corresponding symmetrical transverse groove are parallel to the adjustment direction of the adjustment device.
[0011] Furthermore, the end face of the hinge stop and the surface of the adjacent receiving section (and / or the surface within the shaft element receiving section) are flat, so that in the clamping position, these two flat surfaces can fit tightly against each other. This ensures a large-area, gapless connection between the hinge stop and the shaft element in the clamping position. In this way, the load on the adjusting device is significantly reduced in the clamped state, avoiding spontaneous adjustment.
[0012] As another advantageous feature, the height of the cylindrical receiving sleeve of the frame hinge component can be adjusted relative to the frame hinge component via an adjustable adjusting bolt located along the longitudinal axis of the shaft element. This also enables vertical adjustment on the shaft element in a simple manner.
[0013] Additionally, a cover plate is provided at the lower part of the frame hinge component to cover the adjusting bolt responsible for vertical adjustment. This cover plate is fixed to the adjusting bolt or the receiving sleeve by a fixing bolt. The cover plate, fixed by the fixing bolt, also serves as a reverse locking mechanism, preventing the adjusting bolt from being accidentally twisted after being adjusted to the appropriate position.
[0014] Finally, a cylindrical sleeve-shaped cover is provided, which is slidably mounted on the shaft element having a receiving section for the hinge baffle. The inner diameter of the sleeve's cylindrical opening can reach up to the width of the hinge baffle receiving section. Because the shaft element is solid, the hinge can be used without the sliding cover without any visible axial positional deviation. However, a cover can be provided to conceal and protect the connecting elements of the adjusting bolt and clamp. This cover only needs to leave a very small gap for the hinge baffle to pass through. Depending on the adjusted position of the hinge baffle relative to the shaft element, the cover can be rotated accordingly to more fully cover the shaft element. Attached Figure Description

[0020] Implementation
[0021] Figure 1 The main components of the hinge of the present invention are shown. The frame hinge component (1) and the sash hinge component (4) are arranged in a stacked manner. For better display, the shaft element (7) is shown separately to the side. The frame hinge component (1) includes a mounting section (2) installed in a recess in the door or window frame, and a cylindrical receiving sleeve (3) for accommodating the pin section (8) of the shaft element (7). The sash hinge component (4) includes a mounting section (5) installed in a recess in the door sash, and a hinge baffle (6) that can be inserted into the receiving section (10) of the upper part (9) of the shaft element (7). The width of the hinge baffle (6) is narrower than the receiving section (10) of the shaft element (7) to allow for adjustment distance.
[0022] After the hinge stop (6) is inserted into the shaft element, it can be moved perpendicular to the longitudinal axis of the shaft element (7) by the adjusting device (11). In addition, symmetrical clamping blocks (12) with transverse cuts are provided, each embedded in a corresponding symmetrical transverse slot (14). These transverse cuts are parallel to the moving direction of the adjusting device (11). The clamping blocks (12) are connected to the shaft element (7) by connecting elements (13) (bolts in this case).
[0023] The longitudinal axis direction of the bolt, the adjustment direction of the adjustment device (11), and the longitudinal axis direction of the shaft element (7) are perpendicular to each other.
[0024] Figure 2 A partial cross-sectional view in the assembled state is shown. The clamping block (12) is fixed in the receiving section (10) of the shaft element (7) by the connecting element (13). The clamping block (12) can move between the loosened position and the clamped position by loosening or tightening the connecting element (13). In the clamped position, the end face of the hinge baffle (6) contacts or abuts against the corresponding surface in the receiving section (10) of the shaft element (7). In this embodiment, the two planes above and below the hinge baffle are respectively connected to the planes of the adjacent portions of the top and bottom edges of the receiving section (10). In the loosened position, the position of the hinge can be adjusted by the adjusting device (11). After tightening the connecting element (13), the hinge baffle (6) will no longer have gaps in the receiving section (10), thus reducing the load on the adjusting device (11) in transmitting the internal force of the hinge.
[0025] Figure 3Another schematic cross-sectional view of the hinge of the present invention is shown. In the frame hinge component (1), the position of the receiving sleeve (3) for the pin section (8) is adjustable axially along the shaft element (7). The vertical distance between the frame hinge component (1) and the sash hinge component (4) can be adjusted by the adjusting bolt (15) located below. To prevent the adjusting bolt (15) from rotating accidentally, a cover plate (16) is provided below it, which is fixed to the receiving sleeve (3) by a fixing bolt (17). The fixing bolt (17) acts as a stop for the adjusting bolt (15), fixing the receiving sleeve (3) to the adjusting bolt (15), thereby fixing the adjusting bolt in the corresponding set position. The fixing bolt (17) can also directly lock the adjusting bolt (15).
[0026] Figures 4 to 6 The different adjustment positions of the frame hinge component (1) and the sash hinge component (4) are shown in schematic cross-sectional view. As shown, the receiving section (10) is wider than the insertion part of the hinge baffle (6) by a distance that can be used for adjustment. Figure 4 The hinge baffle (6) is adjusted by the adjusting device (11) to the leftmost end of the receiving section (10). Figure 5 In the middle, the hinge baffle (6) is located in the middle of the receiving section (10). Figure 6 In the middle, the hinge stop (6) is located at the rightmost end. In addition to adjustment by the adjusting device (11) (here, the worm gear in the receiving section (10)), when the clamp (12) is in the loose position, the clamp can also be used as a guide device for the hinge stop (6), so that the hinge stop moves in a straight line within the receiving section. The clamp (12) is located above and below the adjusting device (11), and the transverse cut and transverse groove (14) of the clamp are parallel to the adjusting direction of the adjusting device (11).
[0027] A cylindrical sleeve-shaped cover (18) is fitted over the shaft element (7) from the outside to cover the connecting element (13) used by the adjusting device (11) and the fixing clamp (12). The cover (18) can be rotated accordingly depending on the adjustment position of the hinge baffle (6) to allow the hinge baffle (6) to pass through the receiving section.
