Description
- The present invention relates to a hydraulic hinge, especially for a hydraulic hinge for a glass door.
- A glass door is pivotally mounted on a doorframe by a hydraulic hinge. A conventional hydraulic hinge has a fixing plate, a rotating seat, a pivot and a buffer module. The fixing plate is mounted on the doorframe. The rotating seat is mounted on the glass door and has an oil chamber for storing oil and an oil passage communicating with the oil chamber. The pivot has a first portion, a second portion and an eccentric cam. The first portion of the pivot is mounted on the fixing plate and the second portion of the pivot is mounted into the rotating seat. The eccentric cam is located in the rotating seat. The buffer module is mounted on the rotating seat and is located in the oil chamber of the rotating seat. The buffer module has a valve and a spring. The valve has a through hole for receiving the pivot and a fixing element for abutting against the eccentric cam. The valve has a recess communicating with the through hole and the oil passage, a first oil hole and a second oil hole. The first oil hole and the second oil hole communicate with the recess and the oil chamber. The spring abuts against the rotating seat and the valve.
- When the glass door is pivoted, the rotating seat is rotated relative to the fixing plate. The eccentric cam of the pivot abuts the fixing element of the valve for controlling the valve to press the spring and drive oil in the oil chamber. However, the valve is structurally complex, thereby complicating the manufacturing process. Additionally, the rotating seat provides only a single oil passage, so the glass door is closed slowly such that cool air generated by an air-conditioner escapes from the house.
- To overcome the shortcomings, the present invention provides a hydraulic hinge to mitigate or obviate the aforementioned problems.
- The main object of the present invention is to provide a hydraulic hinge for a glass door; the hydraulic hinge has a fixing plate, a rotating seat, a pivot and a buffer module.
- The rotating seat has a body, an oil chamber, a first oil passage and a second oil passage. The oil chamber, the first oil passage and the second oil passage are formed in the body. The first oil passage has a first inlet and a first outlet. The first inlet and the first outlet are in communication with the oil chamber respectively. The second oil passage has a second inlet and a second outlet. The second inlet is in communication with the first oil passage. The second outlet is in communication with the oil chamber and is disposed between the first inlet and the first outlet.
- The pivot is combined with the fixing plate and the rotating seat, and has a first portion, a second portion and an abutted surface. The first portion is mounted steadily on the fixing plate. The second portion is opposite to the first portion and is mounted rotatably into the rotating seat. The abutted surface is formed on the pivot and is located in the oil chamber of the rotating seat. The abutted surface is flat.
- The buffer module is mounted in the rotating seat and is located in the oil chamber of the rotating seat and has a valve and a spring. The valve abuts against the pivot. The valve has an outer surface, a first surface, a second surface, an axial hole, a ball, a baffle, a circular groove and a radial hole. The first surface abuts against the pivot. The second surface is opposite to the first surface. The axial hole is formed through the valve and has a first opening and a second opening. The first opening is formed on the first surface. The second opening is formed on the second surface. The ball is mounted in the axial hole of the valve. The baffle is mounted on the first opening of the axial hole and has a via hole communicating with the oil chamber and the axial hole. The circular groove is formed around the outer surface of the valve. The radial hole is formed radially in the valve and is in communication with the axial hole and the circular groove. The spring is mounted in the oil chamber of the rotating seat and has a first end and a second end. The first end abuts against the body of the rotating seat. The second end is opposite to the first end and abuts against the second surface of the valve.
- The fixing plate of the hydraulic hinge is mounted on a doorframe. The rotating seat is mounted on a glass door. When the glass door is closed to a specific angle, the circular groove of the valve communicates with the second oil passage, and then oil in the oil chamber can flow through the circular groove of the valve, the radial hole of the valve, and further flow out the second surface of the valve. Therefore, the refluxing of oil in the hydraulic hinge is increased to increase the velocity of repositioning the rotating seat and the velocity of closing the glass door. Thus, the velocity of closing the glass door increases gradually from low speed to high speed, such that cool air escaping from the house is reduced. In addition, the valve of the hydraulic hinge is structurally simple, thereby simplifying the manufacturing process.

Thetoothed part 32 is formed on the first portion of thepivot 30, and the cambered surface 14 of thelid 13 of the fixingplate 10 abuts against thetoothed part 32 of thepivot 30. - The
buffer module 40 is mounted in therotating seat 20 and is located in theoil chamber 22 of therotating seat 20. Thebuffer module 40 has avalve 41 and aspring 42. Thevalve 41 abuts against thepivot 30. Thevalve 41 has an outer surface, afirst surface 43, asecond surface 44, anaxial hole 45, aball 46, abaffle 47, acircular groove 48 and aradial hole 49. Thefirst surface 43 abuts against thepivot 30. Thesecond surface 44 is opposite to thefirst surface 43. - With further reference to
Figs. 4 and 5 , theaxial hole 45 is formed through thevalve 41 and has afirst opening 451 and asecond opening 452. Thefirst opening 451 is formed in thefirst surface 43 and thesecond opening 452 is formed in thesecond surface 44. Theball 46 is mounted in theaxial hole 45 of thevalve 41. Thebaffle 47 is mounted in thefirst opening 451 of theaxial hole 45 and has a viahole 471 communicating with theoil chamber 22 and theaxial hole 45. - With further reference to
Fig. 9 , thecircular groove 48 is formed around the outer surface of thevalve 41. Theradial hole 49 is formed radially in thevalve 41 and is in communication with theaxial hole 45 and thecircular groove 48. - The
spring 42 is mounted in theoil chamber 22 and has a first end and a second end. The first end of thespring 42 abuts against thebody 21 of therotating seat 20. The second end of thespring 42 abuts against thesecond surface 44 of thevalve 41. - With reference to
Figs. 1 and2 , the hydraulic hinge in accordance with the present invention may further have afirst cover 17 and asecond cover 18. Thefirst cover 17 and thesecond cover 18 are symmetrically mounted on thebody 21 of therotating seat 20. With reference toFigs. 10 and11 , the rotatingseat 20 further has afirst adjustment element 25 and asecond adjustment element 26. Thefirst adjustment element 25 is mounted in thebody 21 of therotating seat 20, extends into thefirst oil passage 23 and faces thefirst outlet 232. Thesecond adjustment element 26 is mounted in thebody 21 of therotating seat 20, extends into thesecond oil passage 24 and faces thesecond outlet 241. With reference toFig. 6 , theoil chamber 22 is divided into a first space and a second space by thevalve 41. The first space is located outside the valve relative to thefirst surface 43 of thevalve 41. The second space is located outside the valve relative to thesecond surface 44 of thevalve 41. - With reference to
Fig. 12 , the fixingplate 10 is mounted on a doorframe bymultiple screws 16 that are inserted through the throughholes 15 respectively. Therotating seat 20 is mounted on aglass door 60. With reference toFig. 6 , when theglass door 60 is closed, thefirst surface 43 abuts against the abuttedsurface 31 of thepivot 30. With reference toFigs. 7 and8 , when theglass door 60 is open, the rotatingseat 20 and thebuffer module 40 are pivoted relative to thepivot 30 and the fixingplate 10. The contacted area between thefirst surface 43 and the abuttedsurface 31 is reduced, and thevalve 41 is moved by thepivot 30 and further presses thespring 42. Accordingly, oil in the second space is compressed and flows into theaxial hole 45 of thevalve 41 to push theball 46 and flows through the viahole 471 of thebaffle 47 and into the first space. - With reference to
Fig. 10 , when theglass door 60 is closed, oil in the first space reflows and pushes theball 46 to close theaxial hole 45. Then, oil in the first space flows into thefirst oil passage 23 of therotating seat 20 and flows out of thefirst outlet 232 of thefirst oil passage 23 and into the second space. Thevalve 41 is moved toward thepivot 30 by the restoring force of thespring 42. The contacted area between thefirst surface 43 and the abuttedsurface 31 is increased, and then theglass door 60 is closed slowly. - When the
glass door 60 is closed to a specific angle, a passage between thegrass door 60 and thedoorframe 50 cannot provide enough space for users to pass through. With reference toFigs. 9 and11 , when thevalve 41 is moving a distance, thecircular groove 48 of thevalve 41 is in communication with thesecond oil passage 24 of therotating seat 20. Oil in the first space further flows into thesecond oil passage 24 via thefirst oil passage 23. Then, oil passes through thesecond outlet 241 of thesecond oil passage 24, theradial hole 49 of thevalve 41, and theaxial hole 45 of thevalve 41, and then flows into the second space to increase the refluxing of oil flowing into the second space. Thus, the velocity of closing theglass door 60 gradually increases from low speed to high speed. - If the combination positions of the hydraulic hinge and the
glass door 60 are offset from each, thelid 13 of the fixingplate 10 can be disassembled for adjusting thepivot 30. When the adjustment of thepivot 30 is finished, thelid 13 of the fixingplate 10 can be reassembled and thetoothed part 32 of thepivot 30 abuts against the cambered surface 14 of thelid 13 for increasing the combination stability between thepivot 30 and the fixingplate 10. Furthermore, the amount of oil flowing out of thefirst outlet 232 is controlled by thefirst adjustment element 25, and the amount of oil flowing out thesecond outlet 241 is controlled by thesecond adjustment element 26. - Accordingly, the
circular groove 48 of thevalve 41 communicates with thesecond oil passage 24 when theglass door 60 is closed to a specific angle, and then oil can flow through thecircular groove 48 of thevalve 41, theradial hole 49 of thevalve 41, and further flow into the second space. Therefore, the refluxing of oil in the hydraulic hinge is increased, and the velocity of repositioning the rotating seat and the velocity of closing theglass door 60 are increased. Thus, the velocity of closing theglass door 60 gradually increases from low speed to high speed for reducing the cool air escaping from the house. In addition, thevalve 41 of the hydraulic hinge is structurally simple, thereby simplifying the manufacturing process.
