Technical Field

[0001] The present invention relates to a hinge for connecting a door, a window or the like to a fixed structure, and in particular to an improved adjustable hinge. Background Art

[0002] Adjustable hinges are well known and in one known type, adjustment is made by loosening a set screw connecting the hinge piece to the door / jamb. This usually means that the door must be supported from the outside before adjustment can be made.

[0003] In order to make adjustments in two basically vertical horizontal directions without completely loosening all the blade fixing screws, so that the user can easily achieve on-site adjustment without providing support for the door, the applicant proposed a prior patent application (application number 201811569864.X, invention name: adjustable hinge). An adjustable hinge includes at least two hinge parts that can pivot relative to each other; the first part of the hinge part includes: a joint part and a blade part, and the two parts can be adjusted relative to each other along a first adjustment direction basically parallel to the door surface; a threaded adjustment member, which can be selectively rotated around an axis consistent with the first adjustment direction to achieve relative adjustment of the joint part and the blade part; at least one threaded isolation column, which can be selectively rotated around a virtual pivot point consistent with the second adjustment direction to achieve adjustment of the joint part and the blade part. The hinge structure uses a set of fixing screws for adjustment in two directions. When adjusting, the fixing screws need to be released and then adjusted in the corresponding direction. After adjustment, the fixing screws need to be tightened. When retightening the fixing screws, it will be found that adjusting the displacement in one direction in the released state will cause the position in the other direction to deviate. The adjustments in the two directions will affect each other, thereby affecting the stability of the hinge. Summary of the invention

[0046] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0047] See also Figure 1The present invention provides an improved adjustable hinge for connecting doors, windows and the like, and the improved adjustable hinge has the ability to be adjusted in three directions, including the vertical direction (z-axis), the horizontal direction (x-axis, i.e., the width direction) and the lateral direction (y-axis, i.e., the sealing compression direction). The ability to adjust refers to adjusting the displacement of the door panel or window panel relative to the frame extrusion, and the present invention mainly focuses on horizontal and lateral adjustments. The improved adjustable hinge of the present invention is used to solve the problem that when adjusting the hinge of the previous design, the fixed state is released to adjust the displacement in one direction, which will cause the position in another direction to deviate. The improved adjustable hinge of the present invention ensures that it can be adjusted independently in two directions to avoid interference with each other. The structure of an improved adjustable hinge of the present invention is described below in conjunction with the accompanying drawings.

[0048] See also Figure 1 , showing a three-dimensional structural schematic diagram of the first embodiment of the improved adjustable hinge of the present invention. Figure 2 , shows a three-dimensional structural schematic diagram of another perspective of the first embodiment of the improved adjustable hinge of the present invention. Figure 1 and Figure 2 , the structure of the improved adjustable hinge of the present invention is described.

[0049] like Figure 1 and Figure 2 As shown, the improved adjustable hinge 20 of the present invention includes at least two hinge parts that rotate relative to each other. Figure 1 and Figure 2 Two hinge components are shown, namely, a first hinge component 21 and a second hinge component 22, wherein the first hinge component 21 and the second hinge component 22 can be relatively rotated and adjusted through a pin shaft 24. The first hinge component 21 includes a fixed portion 211, a blade portion 212 and a connecting portion 213, wherein the connecting portion 213 can be adjusted relative to the blade portion 212 in a first adjustment direction, which is the x-axis direction; the blade portion 212 can be adjusted relative to the fixed portion 211 in a second adjustment direction, which is the y-axis direction, and when the blade portion 212 is adjusted, it can be adjusted together with the connecting portion 213, and the second adjustment direction is perpendicular to the first adjustment direction.

[0050] like Figure 3As shown, the improved adjustable hinge 20 of the present invention is connected to the frame extrusion 11. The frame extrusion 11 to which the improved adjustable hinge 20 is connected can be a door frame, a window frame or a fixed structure for installing other similar objects. When the frame extrusion 11 is a door frame, the improved adjustable hinge 20 of the present invention is used to connect a door panel, wherein the first adjustment direction can be defined as a direction that is basically horizontal and parallel to the surface of the door panel, and the second adjustment direction can be defined as a direction that is basically perpendicular to the surface of the door panel.

[0051] When the improved adjustable hinge 20 of the present invention is used to install a door panel, the first hinge component 21 can be connected to the frame extrusion connected to the door panel, and the second hinge component 22 is connected to the frame extrusion installed at the door opening; or the first hinge component 21 is connected to the frame extrusion installed at the door opening, and the second hinge component 22 is connected to the frame extrusion connected to the door panel.

[0052] In a specific embodiment of the present invention, Figure 1 and Figure 2 As shown, the improved adjustable hinge 20 of the present invention further includes a threaded adjustment member 23 rotatable around an axis consistent with the second adjustment direction, and the threaded adjustment member 23 is used to adjust the position of the blade part 212 relative to the fixed part 211 .

[0053] In the first embodiment, if Figure 1 , Figures 3 to 5 As shown, the first hinge component 21 is connected to one of the door, window structure and fixed structure, and the door, window structure and fixed structure are all installed with frame extrusions 11, that is, the first hinge component 21 is connected to the corresponding frame extrusion 11, and a guide groove is provided on the frame extrusion 11, and the threaded adjustment member 23 is inserted into the guide groove and the threaded adjustment member 23 can be rotated and adjusted in the guide groove.

[0054] The guide groove limits the position of the threaded adjustment member 23 in the second adjustment direction, but does not limit the rotation of the threaded adjustment member 23. The threaded adjustment member 23 is threadedly connected to the corresponding part of the blade part 212. In this way, when the threaded adjustment member 23 is rotated and adjusted, the blade part 212 can be moved and adjusted along the threaded adjustment member 23, thereby realizing the movement and adjustment of the blade part 212 relative to the fixed part 211 in the second adjustment direction.

[0055] Preferably, if Fig.10 and Fig.12As shown, a C-shaped groove 111 is provided on the frame extrusion part 11, and the C-shaped groove 111 is used to install the hinge part on the improved adjustable hinge 20. The C-shaped groove 111 can be used as a guide groove at the position corresponding to the threaded adjustment member 23 to clamp the threaded adjustment member 23, thereby limiting the displacement of the threaded adjustment member 23 without limiting the rotation adjustment of the threaded adjustment member 23.

[0056] In the second embodiment, if Fig.13 and Fig.14 As shown, an adjustment groove 2111 is provided on the fixed part 211; the blade part 212 is provided with an adjustment part located in the adjustment groove 2111; the threaded adjustment member 23 is rotatably provided in the adjustment groove 2111, and the threaded adjustment member 23 is threadedly connected to the adjustment part, and the adjustment part can be moved and adjusted along the second adjustment direction in the adjustment groove 2111 by screwing the threaded adjustment member 23.

[0057] like Figures 16 to 21 As shown, the size of the adjustment portion of the blade portion 212 located in the adjustment slot 2111 is smaller than the size of the adjustment slot 2111 , so that the adjustment portion can be moved and adjusted in the adjustment slot 2111 .

[0058] Furthermore, if Figure 1 , Figure 2 and Fig.13 As shown, an adjustment hole 2112 is opened on the fixing part 211; a connecting hole corresponding to the adjustment hole 2112 is opened on the blade part 212; the blade part 212 and the fixing part 211 are fastened together by a threaded fastener 25 that passes through the adjustment hole 2112 and is threadedly connected to the connecting hole.

[0059] The adjustment hole 2112 provides a displacement adjustment function for the threaded fastener 25, and the threaded fastener 25 is used to fasten the blade part 212 and the fixed part 211 after the blade part 212 and the fixed part 211 have completed the relative position adjustment, so that the blade part 212 and the fixed part 211 are in a fixed state, and the blade part 212 cannot be adjusted relative to the fixed part 211. If adjustment is required, the threaded fastener 25 can be loosened to release the fixed state of the blade part 212, and then the position of the blade part 212 can be adjusted along the second adjustment direction by screwing the threaded adjustment member 23.

[0060] The process of displacement adjustment of the blade part 212 and the fixing part 211 along the second adjustment direction of the present invention is as follows: Figures 19 to 21 As shown, when the threaded fastener 25 is in a loosened state, the blade portion 212 can be adjusted relative to the fixing portion 211, and the position of the blade portion 212 can be adjusted along the adjustment hole 2112 by screwing the threaded adjustment member 23. Fig.19In the state shown, the adjusting portion of the blade portion 212 is in contact with the side wall on the right side of the adjusting slot 2111 of the fixing portion 211. Fig. 20 In the state shown, the adjustment portion of the blade portion 212 is located in the middle of the adjustment slot 2111. Fig.21 In the state shown, the adjusting portion of the blade portion 212 is in contact with the side wall on the left side of the adjusting groove 2111 .

[0061] Furthermore, scale marks are provided on the fixing portion 211 or the blade portion 212 . Figures 19 to 21 In the example shown, a scale mark 2122 is provided on the blade portion 212, and the scale mark 2122 is plus or minus 1 mm, and a positioning mark is provided at the fixed portion 211. According to the scale mark pointed to by the positioning mark, the displacement adjustment amount of the blade portion 212 can be easily read. The scale mark is adapted to the adjustment range of the blade portion 212 in the second adjustment direction.

[0062] In a specific embodiment of the present invention, Fig.13 As shown, there are two fixing parts 211, which are arranged at the upper and lower sides of the blade part 212, and there are two threaded adjustment members 23, which are arranged at the upper and lower sides of the blade part 212. Fig.14 and Fig.15 As shown, an adjustment groove 2111 is provided at the bottom of the upper fixing part 211, and an adjustment groove 2111 is provided at the top of the lower fixing part 211. The adjustment groove 2111 is preferably U-shaped, and the height of one side wall of the adjustment groove 2111 is smaller than the height of the other side wall. A part of the threaded adjustment member 23 can be exposed on the side with the smaller side wall height to facilitate the screwing operation of the threaded adjustment member 23.

[0063] In a specific embodiment of the present invention, Figure 1 , Figure 2 and Fig.13 As shown, the fixing portion 211 is substantially in the shape of a flat plate. Fig.11 and Fig.12 As shown, a clamping strip adapted to the C-shaped groove 111 of the frame extrusion member 11 is provided at the back of the fixing portion 211. The shape of the fixing portion is not limited to the shape shown, and it can also be designed to be other shapes.

[0064] like Figure 1 , Figure 2 , Fig.10 and Fig.11As shown, at least one mounting hole is provided on the fixing part 211, and a threaded connector 32 is connected to the mounting hole. A pad 31 is attached to the back of the fixing part 211, and the pad 31 is threadedly connected to the threaded connector 32. The fixing part 211 is fastened to the frame extrusion 11 through the pad 31 and the threaded connector 32. The pad 31 and the fixing part 211 are both inserted into the C-shaped groove 111 on the frame extrusion 11. If the thickness of the frame extrusion 11 meets the connection requirements of the screw, the pad 31 can be omitted, and the threaded connector 32 can be directly used to fasten the fixing part 211 to the frame extrusion 11.

[0065] Fig.10 As shown in , two threaded connectors 32 are arranged on the fixing part 211, and the fixing part 211 is fastened to the corresponding frame extrusion 11 by using the two threaded connectors 32. Through the arrangement of the threaded connectors 32, the fixing part 211 can be fixedly connected to the corresponding frame extrusion 11, and the fixing part 211 and the corresponding frame extrusion 11 are in a relatively fixed state. The threaded connector 32 is preferably a screw, and the threaded connector 32 can also be a bolt, a screw, a self-tapping screw, etc.

[0066] In a specific embodiment of the present invention, Figures 1 to 5 As shown, it also includes a threaded spacer column 27 that can rotate around an axis consistent with the first adjustment direction. The threaded spacer column 27 is used to adjust the position of the connecting part 213 relative to the blade part 212.

[0067] Furthermore, combined with Figure 6 and Figure 7 As shown, a threaded hole is opened in the blade part 212 corresponding to the threaded spacer column 27; a through hole is opened in the connecting part 213 corresponding to the head of the threaded spacer column 27; a push plate is provided on the threaded spacer column 27, the threaded spacer column 27 is threadedly connected to the threaded hole, and the push plate can push the connecting part 213 to adjust the position of the connecting part.

[0068] The threaded spacer column 27 also includes a threaded portion, which is threadedly connected to the threaded hole on the blade portion 212. A push plate is arranged between the threaded portion and the head, and the head is located at the through hole. An operating tool such as a screwdriver can be inserted from the through hole to screw the threaded spacer column 27, so that the threaded spacer column 27 is screwed into the threaded hole or unscrewed from the threaded hole. When the threaded spacer column 27 is unscrewed from the threaded hole, the push plate can push the connecting portion 213 outward to adjust the position of the connecting portion 213 relative to the blade portion 212 along the first adjustment direction.

[0069] Furthermore, a threaded fixing member 29 is further included to fasten and connect the blade portion 212 and the connecting portion 213. After the threaded spacer 27 adjusts the position of the connecting portion 213, the threaded fixing member 29 is screwed to fasten and connect the blade portion 213 and the connecting portion 213.

[0070] The threaded fixing member 29 plays a fixing role. The threaded fixing member 29 can lock the blade part 212 and the connecting part 213, so that the connecting part 213 and the blade part 212 cannot be adjusted relative to each other. When the position of the connecting part 213 needs to be adjusted, the threaded fixing member 29 can be loosened, and then the threaded spacer column 27 is screwed. After the adjustment is completed, the threaded fixing member 29 is tightened. Preferably, the blade part 212 is provided with a threaded connection hole corresponding to the threaded fixing member 29, and the threaded fixing member 29 is screwed to the threaded connection hole.

[0071] In a preferred embodiment of the present invention, Figure 5 As shown, a groove is provided on the blade part 212 corresponding to the threaded spacer column 27, and the groove is used to accommodate the push plate on the threaded spacer column 27. Correspondingly, a protrusion is provided on the connecting part 213 corresponding to the groove, and the protrusion is inserted into the corresponding groove and abuts against the push plate.

[0072] Furthermore, a threaded spacer column 27 is respectively provided at the upper part and the lower part of the blade portion 212 , and the threaded fixing member 29 is disposed close to the threaded spacer column 27 .

[0073] The blade portion 212 is substantially in the shape of a flat plate. Of course, the shape of the blade portion 212 is not limited thereto, and it may also be designed in other shapes.

[0074] like Figure 8 and Fig. 9 As shown, the connecting portion 213 is sleeved on the blade portion 212. Preferably, the connecting portion 213 is generally U-shaped, and a convex strip is provided on the blade portion 212 corresponding to the connecting portion 213, and the U-shaped connecting portion 213 is sleeved on the convex strip, so that when the blade portion 212 is adjusted along the second adjustment direction, the connecting portion 213 can be adjusted together, and the connecting portion 213 can be independently adjusted relative to the blade portion 212 along the first adjustment direction, and the position adjustment in the two directions can be independent of each other without interference.

[0075] A scale mark 2121 is provided on the side of the convex strip of the blade portion 212, and the displacement adjusted by the connecting portion 213 can be conveniently read out by using the scale mark 2121. Preferably, the adjustment range of the connecting portion 213 along the first adjustment direction is plus or minus 2 mm, and the marking range of the scale mark is also plus or minus 2 mm. Of course, the adjustment range of the connecting portion is not limited to this, and it can be designed according to actual needs.

[0076] The connection part 213 can be positioned at the 0 scale when shipped from the factory, and can be adjusted in the positive and negative directions according to the actual situation during actual installation and use. During adjustment, one rotation of the threaded spacer column is equivalent to a displacement adjustment of 1 mm.

[0077] In a second embodiment of the present invention, Fig.13 As shown, an adjustment groove 211 is provided on the fixed part 211, so that when connecting with the frame extrusion, the C-shaped groove provided on the frame extrusion can be omitted, and other forms of connection with the fixed part 211 can be used. For example, the frame extrusion can form a connecting plane directly connected to the fixed part 211, and a groove with a U-shaped cross-section can be provided on the frame extrusion, and the fixed part 211 is embedded in the groove to achieve connection.

[0078] like Figures 1 to 5 As shown, the first hinge component 21 and the second hinge component 22 are rotatably connected through the pin shaft 24. The second hinge component 22 includes an upper mounting portion 221 and a lower mounting portion 222. The upper mounting portion 221 and the lower mounting portion 222 are both sleeved on the pin shaft 24 and can be rotatably adjusted in the z-axis direction relative to the pin shaft 24. The upper mounting portion 221 can be fixedly connected to the corresponding frame extrusion component 11 through a threaded connection 32 and a pad 31, and the lower mounting portion 222 can be highly connected to the corresponding frame extrusion component 11 through a threaded connection 32 and a pad 31. Preferably, in combination with Figures 10 to 12 As shown, the frame extrusion 11 is provided with a C-shaped groove corresponding to the upper mounting portion 221 and the lower mounting portion 222, and the upper mounting portion 221 and the corresponding pad 31 are inserted into the corresponding portion of the C-shaped groove, and the lower mounting portion 222 and the corresponding pad 31 are inserted into the corresponding portion of the C-shaped groove. Of course, if the thickness of the frame extrusion 11 meets the fixing requirements of the screw, the pad 31 can be omitted, and the threaded connector 32 can be directly screwed onto the frame extrusion 11. In this way, the C-shaped groove provided on the frame extrusion 11 can be replaced by a U-shaped groove, or a connecting plane is formed on the frame extrusion 11 to be directly connected to the corresponding mounting portion.

[0079] like Figure 1 and Figure 2 As shown, the connecting portion 213 includes a clamping portion that is clamped on the blade portion 212, a transition portion connected to the clamping portion, and a sleeve portion connected to the transition portion. The sleeve portion is sleeved on the pin 24, and the sleeve portion is located in the middle of the pin 24. The sleeve portion is fastened to the pin 24 by screws, and the transition portion protects two parts that are vertically connected to each other, one part is connected to the clamping portion, and the other part is connected to the sleeve portion.

[0080] The improved adjustable hinge of the present invention is provided with a threaded spacer column and a threaded fixing piece in the first adjustment direction. The threaded fixing piece is used to fix the connecting part and the blade part so that the connecting part and the blade part are in a fixed state. When adjustment is required, the threaded fixing piece can be loosened, and then the threaded spacer column is operated to adjust the position of the connecting part. After adjustment, the threaded fixing piece can be tightened to re-fix the connecting part and the blade part.

[0081] A threaded adjustment component is set in the second adjustment direction, and a threaded fastener is also set on the blade part and the fixed part. The threaded fastener is used to fix the blade part and the fixed part so that the blade part and the fixed part are in a fixed state. When adjustment is needed, the threaded fastener can be loosened, and then the threaded adjustment component is operated to adjust the position of the blade part. After adjustment, the threaded fastener is tightened to re-fix the blade part and the fixed part.

[0082] The improved adjustable hinge of the present invention realizes locking in two directions by means of the provided threaded fixings and threaded fasteners. When the corresponding direction needs to be adjusted, it is only necessary to release the locking in the corresponding direction. In this way, when one direction is adjusted, the position in the other direction will not be affected, thus realizing completely independent adjustment.

[0083] The present invention is described in detail above in conjunction with the embodiments of the accompanying drawings.
