Abstract

A hinge assembly comprises: a leaf mechanism (3); operation units (4, 4, 6); and attenuation units (5, 8). The leaf mechanism (3) includes first leaves (311, 321, 331), and second leaves (312, 322, 332) pivotable with respect to the first leaves (311, 321, 331) so that a hinge assembly can be converted between first and second states. Operation modules (4, 4, 6) are mounted to the leaf mechanism (3) and generate an operating force during conversion of the hinge assembly. To generate an attenuation force, the attenuation units (5, 8) are mounted to the leaf mechanism (3). An attenuation force generated by the attenuation units (5, 8) while the hinge assembly is converted into the first state is different from an attenuation force generated by the attenuation units (5, 8) while the hinge assembly is converted into the second state.

Description

[0001] HINGE ASSEMBLAGE [0002]

The present invention relates to a hinge assembly, and more particularly to an adjustable hinge assembly.

Referring to Figs. 1 and 2, a conventional hinge disclosed in Taiwan Patent No. I441987 (Chinese Patent No. I696604) includes a leaf mechanism 11 and a torque providing module 12. [ The leaf mechanism 11 includes a first leaf 111 fixed to a first object (not shown), a second leaf 112 fixed to a second object (not shown), a first leaf 111, And a plurality of second barrels 114 fixed to the second leaf 112. The second barrels 114 are fixed to the first and second leaves 112 and 113, respectively. The first barrel 113 and the second barrel 114 are arranged in an alternating arrangement and pivot relative to each other. The torque providing module 12 includes a central shaft 121 inserted in the first and second barrels 113 and 114 and rotatable with the first barrel 113, And a torsion spring 123 having two opposing ends fixed to the central axis 121 and the inner tube 122, respectively, for restoring the torque.

When an external force is applied to the conventional hinge in the initial state and the first and second leaves 111 and 112 are turned relative to each other, the center shaft 121 and the inner tube 122 are driven to generate a restoring torque The torsion spring 123 is deformed. When the external force is removed, the restoring torque generated by the torsion spring 123 turns the first and second leaves 111 and 112 toward the initial state.

However, high-speed relative swiveling toward the initial state between the first leaf 111 and the second leaf 112 may cause a severe collision between the first object and the second object. On the contrary, in order to prevent relative swinging toward the initial state between the first leaf 111 and the second leaf 112 so as to prevent a severe collision between the first object and the second object, the conventional hinge damping unit When adopted, the relative turning motion away from the initial state of the first leaf 111 and the second leaf 112 can be considerably delayed.

It is therefore an object of the present invention to provide a hinge assembly capable of mitigating at least one of the above-mentioned disadvantages of the prior art.

According to the present invention, the hinge assembly pivotally interconnects the first and second objects, and includes a leaf mechanism, an operating unit, and a damping unit. The leaf mechanism includes a first leaf unit. The first leaf mechanism includes a first leaf fixed to the first object, a second leaf fixed to the second object and capable of pivoting about the first leaf, a plurality of first barrels fixed to the first leaf, And a plurality of second barrels fixed to the two leaves. The first barrel and the second barrel are arranged in an alternating arrangement along the axis. The hinge assembly is operable to be switched between an initial state and an open state. The angle formed between the first leaf and the second leaf when the hinge assembly is in an initial state is different from the angle formed between the first leaf and the second leaf when the hinge assembly is in the open state. The operating unit is mounted on the first and second barrels of the first leaf unit and includes a tubular member, a connecting shaft, and an operating module. The tubular member may rotate together with the first leaf and the first barrel of the first leaf unit. The connecting shaft extends into the tubular member and can rotate with the second leaf and the second barrel of the first leaf unit. The actuation module is disposed within the tubular member and generates an actuating force while the hinge assembly is switched between an initial state and an open state. The damping unit is mounted to the first and second barrels of the first leaf unit and includes an oil tube, a first actuating member, a follower member, and a hydraulic module. The oil tube may rotate together with the first leaf and the first barrel of the first leaf unit. The first actuating member is fixedly disposed in the oil tube and has an inclined cam surface.

Wherein the follower member is movable in a first direction while the hinge assembly is transitioning from an initial state to an open state and in a second direction opposite the first direction while the hinge assembly is transitioning from an open state to an initial state, And is guided by the first actuating member to move relative to the tube. The hydraulic module is disposed in the oil tube so as to generate a damping force when the follower member moves relative to the oil tube. The hydraulic module may be configured such that the damping force generated by the hydraulic module during switching from the initial state to the open state of the hinge assembly is different from the damping force generated by the hydraulic module during the transition from the open state to the initial state of the hinge assembly .

2. Since the angle formed between the first and second leaves of the leaf unit 31, 32, 33 when the hinge assembly is in the initial state is 0 degrees, the hinge assembly can only be switched from the initial state. Thus, whether the first and second objects 21, 22 are right-handed doors or left-handed doors, the user can install the hinge assembly of the present invention between the first object 21 and the second object 22 without confusion have.

3. The hydraulic units 5 and 8 of the present invention each generate a different damping force in response to the movement of the follower members 56 and 84 of the unit in different directions. Therefore, the hinge assembly of the present invention is subjected to different damping forces when switching from the initial state to the open state and when switching from the open state to the initial state.

4. The hydraulic units 5 and 8 and the first and second operation units 4 and 6 of the present invention can be manually adjusted without disassembling the hinge assemblies 100, 200 and 300, respectively. Thus, the characteristics of the hinge assemblies 100, 200, 300 of the present invention can be easily adjusted.

6, the first and second actuating members 54, 55 can rotate together with the oil tube 51, and the follower member 56 can rotate together with the connecting shaft 42 , The cam surface 551 of the second actuating member 55 is moved toward the first actuating member 54 but in the second actuating member 54 in response to the switching of the hinge assembly from the initial state to the open state To move away from the member 55 relative to the oil tube 51 so as to push the second connecting surface 562 of the follower member 56 in order to be able to compress the first oil chamber 501. [ .

At this time, the oil in the first oil chamber 501 is communicated with the communication hole 565 of the follower member 56, the space formed between the annular contact surfaces 5927, the first communication hole 5925, the pin 594, Flows through the clearance between the needle 592 and the valve seat 571 through the clearance between the inner peripheral surface of the needle 592 and the inner peripheral surface of the needle 592, the oil space 5940, the second communication hole 5926, Through the oil passage 57 of the assembly 572 and through the gap between the sleeve piece 595 and the valve seat 571 and the first end opening 5641 of the communication passage 564, 502). The oil flowing from the gap between the needle 592 and the valve seat 571 through the oil passage 572 of the one-way valve assembly 57 causes the valve member 573 to perform a biasing action of the oil elastic member 574. [ So that the oil passage 572 is blocked. The pin 594 moves relative to the needle 592 and moves to the inner peripheral surface of the pin 594 and the needle 592 during the movement of the follower member 56 away from the second actuating member 55 And the channel forming surface), so that the gap corresponding to the position of the first communication hole 5925 is expanded.

Thus, in the initial stage when the hinge assembly is switched from the initial state to the open state, a gap formed between the pin 594 and the inner peripheral surface of the needle 592 and corresponding to the first communication hole 5925, The damping force generated by the hydraulic module is relatively large. A gap formed between the pin 594 and the inner peripheral surface of the needle 592 and corresponding to the position of the first communication hole 5925 is formed by an angle increase between the first leaf 311 and the second leaf 312 The damping force generated by the hydraulic module is relatively small.

14, when the external force is removed, the restoring torque generated by the first torsion spring 44 turns the connecting shaft 42 and the first torque adjusting member 43 relative to each other, To be switched from the open state to the initial state. The cam surface 541 of the first actuating member 54 is configured such that the follower member 56 is directed to the second actuating member 55 but in response to the switching of the hinge assembly from the open state to the initial state, (561) of the follower member (56) so as to move the second oil chamber (502) away from the first oil chamber (54) with respect to the oil tube (51) do.

At this time, the oil flowing from the second oil chamber 502 to the oil passage 572 of the one-way valve assembly 57 pushes the valve member 573 against the valve seat 571 to cut off the oil passage 572, Only the oil in the second oil chamber 502 flows from the first end opening 5641 of the oil passage or communication passage 564 through the gap between the sleeve piece 595 and the valve seat 571, Is defined between the needle 592 and the valve seat 571 through the second communication hole 5926 and through the oil space 5940 to the inner peripheral surface of the pin 594 and the needle 592 Via the first communication hole 5925 and the oil passage defined by the communicating hole 565 of the follower member 56 through the space defined between the annular contact surfaces 5927 via the first communication hole 5925, And flows into the oil chamber 501. As a result, the damping force produced by the hydraulic module during the transition from the open state to the initial state of the hinge assembly is greater than the damping force generated by the hydraulic module during the transition from the initial state to the open state of the hinge assembly.

The valve seat 571 is moved toward the sleeve piece 595 when the angle between the first leaf 311 and the second leaf 312 is substantially zero during the transition from the open state to the initial state of the hinge assembly , Narrowing the gap between the sleeve piece (595) and the valve seat (571); The pin 594 also moves relative to the needle 592 to narrow the gap defined between the pin 594 and the inner peripheral surface of the needle 592 and corresponding to the position relative to the first communication hole 5925, Accordingly, the damping force generated by the hydraulic module becomes even larger.

Referring to Figs. 10 and 15, the first leaf unit 31, the first actuating unit 4, and the damping unit 5 cooperate to form the first hinge assembly 100. In one embodiment, a plurality of first hinge assemblies 100 may be connected between the first object 21 and the second object 22.

17, the sleeve piece 595 is substantially held in the valve seat 571 of the one-way valve 57 so that the clearance between the sleeve piece 595 and the valve seat 571 and the gap between the pin 594 and the needle 594, The gap formed between the inner peripheral surfaces of the first and second communication holes 592 and 592 corresponding to the position of the first communication hole 5925 is narrowed so that the first and second leaves 311 and 312 are rotated with respect to each other The mounting bolt 591 can be rotated to move to the inner limit position relative to the follower member 56. [ 16, when the mounting bolt 591 is rotated to move to the inner limit position of the follower member 56 when the hinge assembly is in the open state, the hinge assembly is removed It can be maintained in the open state.

The one-way valve assembly 57 'includes a valve member 576, an annular gasket 577, and a positioning ring 578. The valve member 576 may be comprised of a plate, bolt, or ball. Positioning ring 578 positions annular gasket 577 relative to follower member 56 such that valve member 576 is movable relative to follower member 56 to allow removal of oil path 566 So as to be movable in a space formed between the annular gaskets 577.

The throttle assembly 7 extends along the axis X through the sleeve member 53, the second actuating member 55, the follower member 56, and the one-way valve assembly 57 '; And includes a mounting bolt 71, a first needle 72, a second needle 73, a pin 74, a fixing member 75, two backup rings 76, and a sealing ring 77. The mounting bolt 71 extends along the axis X through the second actuating member 55 and the sleeve member 53 and engages with the sleeve member 53 in a screwed manner. The first needle 72 is movably mounted to the mounting bolt 71 and extends into the follower member 56 along the axis X. [ The second needle 73 is disposed in the communication passage 564 of the follower member 56 and is screwed to the first needle 72. The pin 74 is screwed into the second needle 73. The fixing member 75 is screwed to the female threaded portion 5643 of the follower member 56. The backup ring 76 is disposed between the first needle 72 and the second needle 73. The seal ring 77 is forcedly clamped between the backup rings 76 for airtight contact with the inner surface of the follower member 56. [ The follower member 56 and the throttle assembly 7 are configured such that when one of the communication holes 565 corresponds to a position relative to the backup ring 76 and the sealing ring 77, One of the communication holes 565 corresponds to a position on the outer peripheral surface of the second needle 73 so that fluid communication between one of the communication holes 565 and the oil groove 567 is allowed to form an oil passage, The fluid communication between one of the communication holes 565 and the oil groove 567 is blocked. The one-way valve assembly 57 'and the throttle assembly 7 cooperate to act as a hydraulic module.

The oil flowing from the first oil chamber 501 through the oil path 566 pushes the valve member 576 causing the oil path 566 to be blocked.

The cam surface 541 of the first actuating member 54 pushes the follower member 56 toward the second actuating member 55 so that the second oil chamber 502 is compressed. The oil in the second oil chamber 502 is prevented from flowing into the oil path 566 by the valve member 576 and flows only into the first oil chamber 501 through the oil groove 567, One of the holes 565 corresponds to the position for backup ring 76 and seal ring 77. As a result, the damping force produced by the hydraulic module during the transition from the open state to the initial state of the hinge assembly is greater than the damping force generated by the hydraulic module during the transition from the initial state to the open state of the hinge assembly.

Due to the misalignment between one of the communication holes 565 and the backup ring 76 and the seal ring 77 during the transition from the open state to the initial state of the hinge assembly, the first leaf 311 and the second leaf 312 The backup ring 76 and the seal ring 77 are moved so as to correspond to the positions of one of the communication holes 565 so as to correspond to one of the communication holes 565 It should be noted that the mounting bolt 71 may be rotated to move relative to the follower member 56 such that fluid communication may be established between the oil groove 567.

The sleeve 832 is for operating to move the main body 831 to the oil tube 81 so that the distance between the projection 8311 and the first actuating member 82 can be adjusted. The adjusting bolt 833 is fixed to the sleeve 831 by a tool (not shown) so that the attenuation coefficient of the body 831 can be adjusted so that the magnitude of the damping force generated by the body 831 can be adjusted when the protrusion 8311 is pressed.
