[0132] Referring to Figures 1A and 1B, which are combined schematic diagrams of an adjustable multi-functional hinge 100 proposed in this invention from different perspectives, and referring to Figures 2A and 2B, which are exploded views of this adjustable multi-functional hinge 100 proposed in this invention, this adjustable multi-functional hinge 100 is suitable for connecting a door leaf 110 and a door frame 120 (please refer to Figure 4A). The adjustable multi-functional hinge 100 is characterized in that it includes two leaf units 10, including a first leaf 11 and a second leaf 12. The first leaf 11 and the second leaf 12 have an annular channel 13 along a first axis X (Figure 2B), and a shaft assembly 40 passes through the annular channel 13 to rotate the first leaf 11 and the second leaf 12 along the first axis X as the axis.

[0133] Referring to Figure 2A, a clamping assembly 20 and a bolt assembly 30 are used to fix the first leaf 11 to the door leaf 110 and the second leaf 12 to the door frame 120. The clamping assembly 20 includes a clamping plate leaf 21 and a plurality of clamping plate gaskets 22, and the bolt assembly 30 includes an expansion unit 31, a bolt unit 32, a bushing 33, and a plug 34. Referring also to Figure 4A, in this embodiment, the first leaf 11 is fixed to the door leaf 110 through the bolt assembly 30, and the second leaf 12 is fixed to the door frame 120 through the bolt assembly 30, thereby allowing the first leaf 11 and the door leaf 110 to rotate. Of course, it can also be adjusted according to actual needs, with the first leaf 11 fixed to the door frame 120 through the bolt assembly 30, and the second leaf 12 fixed to the door leaf 110 through the bolt assembly 30, thereby allowing the second leaf 12 and the door leaf 120 to rotate.

[0134] The clamping plate 21 of the clamping assembly 20 can be made of a hard material, such as metal, to enhance the clamping and locking force, while the plurality of clamping plate pads 22 can be made of a soft material and are disposed between the clamping plate 21 and the contact surface between the door leaf 110 or the door frame 120.

[0135] Referring to Figure 2B, the shaft assembly 40 is inserted into the annular channel 13 and includes a torque-accumulating assembly 41, a damping assembly 42, a spacer ring assembly 43, and a shaft assembly 44 inserted through the torque-accumulating assembly 41, the damping assembly 42, and the spacer ring assembly 43. In this embodiment, the torque-accumulating assembly 41 corresponds to the first leaf 11, and the damping assembly 42 corresponds to the second leaf 12. In this embodiment, the first leaf 11 is installed on the door leaf 110. When the first leaf 11 rotates, it drives the shaft assembly 44 to rotate. In addition, the shaft assembly 40 may also include a cap assembly 50, which is sleeved on the front and rear ends of the shaft assembly 40.

[0136] Please refer to Figures 3A to 3D, which are, in sequence, partially exploded views of the torque-accumulating assembly 41, the damping assembly 42, the spacer ring assembly 43, and the shaft assembly 44. Also refer to Figures 4A to 4G. Figure 4A is a top view of this adjustable multi-functional hinge assembly; Figure 4B is a cross-sectional view of the shaft assembly 40 in the AA direction of Figure 4A; Figure 4C is a cross-sectional view of the shaft assembly 40 in the BB direction of Figure 4A; Figure 4D is a cross-sectional view of the bolt assembly 30 in the CC direction of Figure 4A; Figure 4E is a cross-sectional view of the convex ring portion 4311 in the spacer ring pad 431 in the DD direction of Figure 4D; Figure 4F is a cross-sectional view of the limiting block 432 in the FF direction of Figure 4D; and Figure 4G is a cross-sectional view of the bolt assembly 30 in the GG direction of Figure 4D. The operating states of each component will be described in detail later.

[0137] Referring to Figure 3A, the torque-accumulating assembly 41 includes a first torque-accumulating sleeve 411 and a second torque-accumulating sleeve 412, and a torque-accumulating spring 413, an auxiliary elastic element 414, and a ratchet 415 disposed between the first torque-accumulating sleeve 411 and the second torque-accumulating sleeve 412. The main function of this torque-accumulating assembly 41 is to generate an active pushing force when the door leaf 110 is pushed, causing the first leaf 11 to rotate, thereby causing the door leaf 110 to generate a closing restoring force. Its detailed structure is described in the applicant's Taiwan Patent Publication No. TWI818844B, and will not be repeated here.

[0138] Referring to Figures 3B and 4B, the damping assembly 42 includes an outer tube 421 and a sleeve 422 that can be fitted onto the outer tube 421. An inner assembly 423 is disposed inside the outer tube 421. A regulating valve 424 and a first piston 425 are disposed in the inner assembly 423 along a first axis X, forming a first flow channel 4231. Referring to Figures 3B and 4C, a second piston 426, a first steel ball 427, an elastic element 428, and a first bolt 429 are disposed in the inner assembly 423 along a second axis Y, forming a second flow channel 4232. The regulating valve 424 can adjust the tightness to control the hydraulic pressure in the first flow channel 4231, so that the door can close slowly. When the regulating valve 424 is locked, the entire shaft assembly 40 will be stationary, that is, the door leaf 110 will be stationary. The function and structure of the damping kit 42 are as described in the applicant's Taiwan Patent Publication No. TWI852252B, and will not be repeated here.

[0139] Referring to Figure 3C, the spacer ring assembly 43 includes a spacer ring pad 431 with a protruding ring portion 4311. The protruding ring portion 4311 has a plurality of first openings 4312 for a positioning bead 4313 and a flat-head bolt 4314 to pass through. A limiting block 432, a positioning ring 433, and a disc spring 434 are arranged in the spacer ring pad 431 along the first axis X. Referring also to Figure 4E, after the positioning bead 4313 and the flat-head bolt 4314 pass through the first openings 4312, they abut against the positioning ring 433. The plurality of first openings 4312 are arranged around the protruding ring portion 4311 at 45-degree intervals. The positioning ring 433 has a plurality of curved grooves 4331, corresponding to the plurality of first openings 4312 on the spacer ring pad 431. Accordingly, during installation, the positioning bead 4313 can be installed in the first opening 4312 at which angle according to the actual installation angle requirements. The remaining plurality of second openings 4312 are all fitted with flat head bolts 4314. In addition, please refer to Figures 3C and 4F. The inner wall of the spacer ring pad 431 has a flange portion 4316, and the limiting block 432 has a protruding stop portion 4321. When the limiting block 432 is disposed inside the spacer ring pad 431, when the equal leaf unit 10 rotates and drives the shaft assembly 40 to rotate together, the limiting block 432 rotates together until the protruding stop portion 4321 is stopped by the flange portion 4316 and then stops rotating.

[0140] As shown in Figure 4B, the disc spring 434 can cause the shaft 441 to float in the X-axis direction when it rotates, which is used to adjust the gap between the various components in the shaft assembly 40. When the gap is too tight, the disc spring 434 can reduce the pressure in the X-axis direction of the first axis, so as to prevent the various components in the shaft assembly 40 from being worn or damaged due to excessive pressure in the X-axis direction.

[0141] On the other hand, referring to Figures 3C, 1B and 2B, the spacer ring post 431 has a plurality of second openings 4315 aligned with the plurality of first openings 4312, for providing a fixing screw 4317 to pass through the second leaf 12 toward the shaft assembly 40 and abut against the plurality of second openings 4315. The fixing screw 4317 is used to control the rotation angle of the limiting block 432 and rotate synchronously with the positioning bead 4313.

[0142] Referring to Figure 3D and comparing it with Figure 4C, the shaft assembly 44 includes a shaft member 441 disposed within a shaft sleeve 442. A rubber ring 443, a hyperbolic slide sleeve 444, a plurality of washer 445, and a plurality of disc springs 446 are sequentially inserted through the shaft member 441 toward the spacer ring post 421. The shaft member 441 has a bolt hole 4417. The hyperbolic slide sleeve 444 has a curved slide rail 4441. A bolt 447 passes through the curved slide rail 4441 and is disposed in the bolt hole 4417. The bolt 447 will slide 180 degrees on the curved slide rail 4441 to control the closing speed. Referring to Figure 3D and comparing it with Figure 4B, the shaft 441 has a hollow portion 4411 at one end facing the outer sleeve 422. This hollow portion 4411 is disposed within the inner sleeve 423. A third piston 4412, a second steel ball 4413, and a second bolt 4414 are disposed within the hollow portion 4411, forming a third flow channel 4416. A plurality of plug valves 4415 are sleeved between the hollow portion 441 of the shaft 441 and the inner sleeve 423. Accordingly, the second steel ball 4413 floats within the third piston 4412 due to hydraulic pressure, thereby opening or closing the flow channel. This hydraulic actuation interacts with the aforementioned damping component 42, allowing the door 120 to close slowly.

[0143] As shown in Figures 5A to 5C, Figure 5A is a schematic diagram of the door leaf 110 opening to a 90-degree angle with the door frame 120, Figure 5B is a schematic diagram of the door leaf 110 continuing to open to a 135-degree angle with the door frame 120, and Figure 5C is a schematic diagram of the door leaf 110 fully open to a 180-degree angle with the door frame 120. It can be seen that after the two clamping plates 22 clamp the door leaf 110, a bolt assembly 30 is inserted between the first leaf 11, the door leaf 110, the clamping plates 22 and the clamping plate 21 and locks them in place. Another set of bolt assemblies 30 is inserted between the second leaf 12, the door frame 120, the clamping plates 22 and the clamping plate 21 and locks them in place. Accordingly, when the user opens the door leaf 110, the door leaf 110 drives the first leaf 11 to rotate together. In addition, a sound insulation unit 130 can be provided between the door leaf 110 and the door frame 120. When the door is closed, the gap between the door leaf 120 and the door frame 120 is filled with the sound insulation unit 130, which can insulate against sound and prevent dust from entering.

[0144] Furthermore, please refer to Figure 6A, which shows an adjustable multi-functional hinge 200 according to the second embodiment of the present invention. The difference between this and the first embodiment is that the first leaf 11 and the second leaf 12 of the two leaf units 10 have a turning portion 21, allowing for more flexible application to different installation needs. Please refer to Figure 6B, which is a top view of the adjustable multi-functional hinge 200 in its assembled state according to this embodiment; Figure 6C is a cross-sectional schematic diagram of the bolt assembly 30 in the EE direction of Figure 6B. It can be seen that in this embodiment, the bolt assembly 30 is installed in a different direction than in the first embodiment shown in Figure 4D. That is, the adjustable multi-functional hinge proposed in this invention has more ways to be installed on door panels or door frames.

[0145] Please refer to Figure 7A, which is a schematic diagram of the assembly of the adjustable multi-functional hinge 300 according to the third embodiment of the present invention; Figures 7B and 7C are exploded schematic diagrams of the adjustable multi-functional hinge 300; Figure 7D is a cross-sectional schematic diagram of the adjustable multi-functional hinge 300 after assembly at the bolt assembly 30. It can be seen that the difference between this third embodiment and the first embodiment is that the bolt assembly 30 is installed in a different direction. Therefore, the plug 34 is installed on the first leaf 11 and the second leaf 12.

[0146] Furthermore, it should be noted that Figure 8A is an exploded view of the bolt assembly 30 proposed in this invention; Figure 8B is a schematic diagram of the expansion unit 31 in the retracted state after the bolt assembly 30 is assembled; Figure 8C is a schematic diagram of the expansion unit 31 in the unfolded state after the bolt assembly 30 is assembled; and Figure 8D is a schematic diagram of the bolt assembly 30 inserted between two objects. The expansion unit 31 includes three spring pieces 311, a retaining ring 312, a reset element 313, and a binding ring 314. The bolt unit 32 includes a bolt member 321 and a threaded member 322. Accordingly, one of the equal spring pieces 311 abuts against the buckle ring 312, the binding ring 314 is disposed on the binding belly 3112 of the equal spring pieces 311, and the reset element 313 is surrounded by the three equal spring pieces 311 and disposed below the buckle ring 312. Accordingly, the bolt 321 passes through the center of the buckle ring 312 and the reset element 313 in sequence and then engages with the screw member 322. The buckle ring 312 has a plurality of equidistant protrusions 3121 and three limiting recesses 3122 correspondingly disposed at the joint of the spring pieces 311.

[0147] Accordingly, referring to Figure 8C, when the bolt 321 is screwed into the threaded part 322, the retaining ring 312 will slowly compress the spring piece 311 towards the threaded part 322, and cause one of the barbed ends 3113 of the spring piece 311 to open outward (expand), so that the barbed end 3113 abuts against the bushing 33. The barbed end 3113 has multiple protrusions, so that the entire bolt assembly 30 more tightly locks the clamping part 20, the door leaf 110, and the door frame 120. Please also refer to Figure 4D, which is a cross-sectional view along the CC direction in Figure 4A. It can be seen that when the bolt unit 32 locks the expansion unit 31, the tail end of the expansion unit will unfold and barb the door leaf 110 or the door frame 120. Furthermore, by adjusting the length of the bolt unit 32 and the length of the bushing 33, it can be flexibly adapted to any thickness of the door leaf 110 or the door frame 120. Of course, the thickness of the door leaf can be adjusted by adjusting the length of the bolt 321, and if the door leaf 110 is hollow, the installation method can be appropriately selected from the aforementioned installation direction.

[0148] It should be noted that, referring to Figure 8D, the structure of this bolt assembly 30 can also be used to lock any two objects to be locked. As shown in Figure 8D, a hole 53 is pre-set between a first object 51 and a second object 52, and the width of this hole 53 is greater than the width of this bolt assembly 30. Then, the bolt assembly 30 is placed into the hole 53, and the bolt 321 and the threaded part 322 are screwed together. After the bolt 321 is tightened, the barb end 3113 of the spring piece 311 unfolds outward (not shown), and is then tightly locked into the inner wall of the hole 53.

[0149] Furthermore, it should be noted that the bolt assembly 30 can have multiple different lengths. In actual use, different lengths of bolt assembly 30 can be selected according to the depth requirements of the assembled objects. For example, please refer to Figure 9A, which is an exploded view of the adjustable multi-functional hinge 400 of the fourth embodiment of the present invention applied to a relatively thick door leaf 110 and door frame 120. Also refer to Figure 9B, which is a partially enlarged cross-sectional view of the adjustable multi-functional hinge 400 of the fourth embodiment of the present invention applied to a relatively thick door leaf 110 and door frame 120 in combination. The lengths of the expansion unit 31, the bolt unit 32, and the bushing 33 in the bolt assembly 30 of this fourth embodiment are selected based on the thickness of the door leaf 110 or door frame 120, plus the thickness of the leaf unit 10. In this embodiment, the bushing 33... A plurality of pre-set holes 140 are pre-embedded in the door leaf 110 and the door frame 120. The bushing 33 further includes a groove 331. Then, the expansion unit 31 is placed into the bushing 33. The expansion unit 31 is joined together by the groove 331. The bolt unit 32 passes through the door leaf 110 and the clamping assembly 20, and the door frame 120 and the clamping assembly respectively, so that the bolt unit 32 is locked into the expansion unit 31. In this embodiment, the plug 34 plugs the bolt unit 32 from the direction of the leaf unit. This can be used for aesthetic purposes and can also prevent the bolt unit 32 from getting damp and rusting.

[0150] Please refer to Figure 9C, which is an exploded view of the adjustable multi-functional hinge 500 of the fifth embodiment of the present invention applied to a thicker door leaf 110 and door frame 120. Also refer to Figure 9D, which is a partially enlarged cross-sectional view of the combined state of the adjustable multi-functional hinge 500 of the fifth embodiment of the present invention applied to a thicker door leaf 110 and door frame 120. The difference between this fifth embodiment and the fourth embodiment is that the bushing 33 includes a stop ring 332. Referring to Figure 9D, this bushing 33 is inserted from the other side into the pre-drilled hole 140 of the door leaf 110 or the door frame 120, causing the stop ring 332 to abut against the other surface of the door leaf 110 or the door frame 120. This embodiment is applicable when construction space is limited, allowing installation from the other direction of the door leaf 110 or the door frame 120. Therefore, the actual product of the adjustable multi-functional hinge proposed in this invention can be more flexibly applied to different thickness requirements and different construction space requirements.

[0151] However, the above description is merely an embodiment of the present invention and should not be construed as limiting the scope of the present invention. Any simple equivalent changes and modifications made in accordance with the claims and patent specification of the present invention shall still fall within the scope of the present invention.
