DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0018] With reference to FIGS. 1 to 4, a hinge mechanism in accordance with the present invention comprises a fixation seat 10, a first guided assembly 20, a second guided assembly 30 and a movable assembly 40.

[0019] With reference to FIGS. 3 and 4, the fixation seat 10 has a first containing indentation 11, a second containing indentation 12, a first guiding element 13 and a second guiding element 14. The first containing indentation 11 and the second containing indentation 12 are arranged axially up and down and opposite to each other, and are in spatial communication with each other. The first guiding element 13 is mounted in the first containing indentation 11. The second guiding element 14 is mounted in the second containing indentation 12.

[0020] With reference to FIGS. 3 and 4, the first guided assembly 20 is mounted at the first containing indentation 11 of the fixation seat 10, corresponds to and abuts the first guiding element 13. The second guided assembly 30 is mounted at the second containing indentation 12 of the fixation seat 10, corresponds to and abuts the second guiding element 14. The first guided assembly 20 is guided by the first guiding element 13 to move away from the second guided assembly 30 or move back to its original position, and the second guided assembly 30 is guided by the second guiding element 14 to move away from the first guided assembly 20 or move back to its original position.

[0021] With reference to FIGS. 1 to 4, the movable assembly 40 comprises a shaft 41 and a door-fixing component 42. The shaft 41 is axially movable and pivotable, and is mounted through the fixation seat 10, the first containing indentation 11 and the second containing indentation 12 of the fixation seat 10. The shaft 41 is optionally connected to one of the first guided assembly 20 and the second guided assembly 30. The door-fixing component 42 is mounted at the shaft 41, such that the door-fixing component 42 is pivotable relative to the fixation seat 10 via the shaft 41. When the shaft 41 is connected to the first guided assembly 20, while the door-fixing component 42 is pivoted, the door-fixing component 42 is moved up and down via the first guided assembly 20 guided by the first guiding element 13. When the shaft 41 is connected to the second guided assembly 30, while the door-fixing component 42 is pivoted, the door-fixing component 42 is moved up and down via the second guided assembly 30 guided by the second guiding element 14.

[0022] With reference to FIGS. 7 to 9, the hinge mechanism is used to install a door plate 50 to an installing surface 60 of a wall or a door frame. The fixation seat 10 is mounted on the installing surface 60, and the door plate 50 is installed to the door-fixing component 42 of the movable assembly 40. A user operates the shaft 41 to connect it with the chosen first guided assembly 20 or second guided assembly 30. When being pushed, the door plate 50 pivots relative to the installing surface 60 via the shaft 41, and is lifted or lowered by cooperation between the first guided assembly 20 and the first guiding element 13 or by cooperation between the second guided assembly 30 and the second guiding element 14. In addition, the door plate 50 can be made of glass, metal or other materials.

[0023] Besides, with reference to FIGS. 3 to 6, the first guided assembly 20 comprises a first moved element 21, a first elastic element 22 and a first connecting element 23. The first moved element 21 is capable of moving up and down, is pivotable, is mounted in the first containing indentation 11, and abuts the first guiding element 13. The first elastic element 22 abuts the first moved element 21 and the door-fixing component 42. The first connecting element 23 is optionally operated to connect the first moved element 21 and the shaft 41. The second guided assembly 30 comprises a second moved element 31, a second elastic element 32 and a second connecting element 33. The second moved element 31 is capable of moving up and down, is pivotable, is mounted in the second containing indentation 12, and abuts the second guiding element 14. The second elastic element 32 abuts the second moved element 31 and the door-fixing component 42. The second connecting element 33 is optionally operated to connect the second moved element 31 and the shaft 41.

[0024] Additionally, the door-fixing component 42 comprises two position-limiting rings 421 mounted on the shaft 41. The first elastic element 22 and the second elastic element 32 respectively abut the two position-limiting rings 421.

[0025] Furthermore, with reference to FIGS. 5 and 6, the shaft 41 has a first screw hole 411 and a second screw hole 412 that are arranged up and down and spaced apart from each other. The first connecting element 23 is threaded and is fastened in the first screw hole 411 of the shaft 41. The second connecting element 33 is threaded and is fastened in the second screw hole 412 of the shaft 41. The shaft 41 is mounted through the first moved element 21 and the second moved element 31. The first moved element 21 has a first cooperating hole 211 corresponding to the first screw hole 411. The second moved element 31 has a second cooperating hole 311 corresponding to the second screw hole 412. By operating the first connecting element 23 to connect the first moved element 21 and the shaft 41, the first connecting element 23 reaches into the first cooperating hole 211 of the first moved element 21. By operating the second connecting element 33 to connect the second moved element 31 and the shaft 41, the second connecting element 33 reaches into the second cooperating hole 311 of the second moved element 31.

[0026] With reference to FIGS. 3 and 4, the first guiding element 13 has one or two first slopes 131. Two ends of the one or two first slopes 131 are away from the second guiding element 14 relative to a middle point of the one or two first slopes 131. The first moved element 21 abuts the one or two first slopes 131 of the first guiding element 13 and is guided by the one or two first slopes 131 to be moved up and down and pivoted. The second guiding element 14 has one or two second slopes 141. Two ends of the one or two second slopes 141 are away from the first guiding element 13 relative to a middle point of the one or two second slopes 141. The second moved element 31 abuts the one or two second slopes 141 of the second guiding element 14 and is guided by the one or two second slopes 141 to be moved up and down and pivoted.

[0027] Moreover, the one or two first slopes 131 of the first guiding element 13 comprise two first inclined segments 132, which are opposite to each other, and a first level segment 133 disposed between the two first inclined segments 132. The first moved element 21 has one or two first cooperating portions 212 abutting the one or two first slopes 131. A contour of the one or two first cooperating portions 212 corresponds to a contour of the one or two first slopes 131. The one or two second slopes 141 of the second guiding element 14 comprise two second inclined segments 142, which are opposite to each other, and a second level segment 143 disposed between the two second inclined segments 142. The second moved element 31 has one or two second cooperating portions 312 abutting the one or two second slopes 141. A contour of the one or two second cooperating portions 312 corresponds to a contour of the one or two second slopes 141. Preferably, an amount of the one or two first slopes 131 of the first guiding element 13 is two, and an amount of the one or two second slopes 141 of the second guiding element 14 is two. Therefore, guidance stability of the first moved element 21 guided by the first guiding element 13 and the second moved element 31 guided by the second guiding element 14 are increased.

[0028] With reference to FIGS. 5 and 6, by operating the first connecting element 23, letting it reach into the first cooperating hole 211 of the first moved element 21 while fastened in the shaft 41, the user can choose to connect the shaft 41 with the first guided assembly 20. Hence, when the shaft 41 pivots, the one or two first cooperating portions 212 of the first moved element 21 move along one of the two first inclined segments 132 of the one or two first slopes of the first guiding element 13, and therefore the door-fixing component 42 is lifted or lowered along with the shaft 41 and the first moved element 21. Alternatively, by operating the second connecting element 33, letting it reach into the second cooperating hole 311 of the second moved element 31 while fastened in the shaft 41, the user can choose to connect the shaft 41 with the second guided assembly 30. Hence, when the shaft 41 pivots, the one or two second cooperating portions 312 of the second moved element 31 move along one of the two second inclined segments 142 of the one or two second slopes 141 of the second guiding element 14, and therefore the door-fixing component 42 is lifted or lowered along with the shaft 41 and the second moved element 31.

[0029] With reference to FIGS. 1 to 4, the fixation seat 10 comprises an assembling plate 15 and a fixation component 16, which is mounted at the assembling plate 15. The first containing indentation 11 and the second containing indentation 12 of the fixation seat 10 are formed in the fixation component 16, which has two penetrating holes 161. The assembling plate 15 can be mounted at the installing surface 60 of a wall or a door frame.

[0030] In addition, the movable assembly 40 comprises a cover 43, which is disposed in the door-fixing component 42 and shields the fixation component of the fixation seat 10, the first guided assembly 20 and the second guided assembly 30. The shaft 41 is mounted through the cover 43, which has two through holes 431 respectively corresponding to the first guided assembly 20 and the second guided assembly 30 in position.

[0031] With reference to FIGS. 4 to 6, when the movable assembly 40 is at a starting position, the two penetrating holes 161 of the fixation component 16 respectively align with the two through holes 431 of the cover 43. The one or two first cooperating portions 212 of the first moved element 21 are completely attached to the one or two first slopes 131 of the first guiding element 13. The first cooperating hole 211 of the first moved element 21 aligns with the first screw hole 411 of the shaft 41 and with one of the two through holes 431 of the cover 43. The one or two second cooperating portions 312 of the second moved element 31 are completely attached to the one or two second slopes 141 of the second guiding element 14. The second cooperating hole 311 of the second moved element 31 aligns with the second screw hole 412 of the shaft 41 and with the other one of the two through holes 431 of the cover 43. Therefore, when the movable assembly 40 is at the starting position, the user can use a tool passing through the two through holes 431 of the cover 43 and the two penetrating holes 161 of the fixation component 16 to operate the first connecting element 23 and the second connecting element 33, so the shaft 41 is connected to one of the first connecting element 23 and the second connecting element 33 and is disconnected from the other.

[0032] With reference to FIGS. 7 to 9, when the door plate 50 is being pushed, the door plate 50, the door-fixing component 42 and the shaft 41 are moved up and down because the shaft 41 is moved with the first guided assembly 20, which is guided by the first guiding element 13, or with the second guided assembly 30, which is guided by the second guiding element 14. Because the first guided assembly 20 and the second guided assembly 30 are guided to move away from each other or move back, the user can install the door plate 50 to any of the left-side and right-side installing surfaces 60. By installing the fixation seat 10 of the hinge mechanism at the installing surface 60 and choosing to connect the shaft 41 with the first guided assembly 20 or the second guided assembly 30, the door plate 50 is lifted and lowered normally. The door plate 50 is lifted when pushed open and is lowered when returning to its original position, that is, when moved away from the original position, the movable assembly 40 lifts the door plate 50, and when moved back to the original position, the movable assembly 40 lowers the door plate 50. Therefore, the hinge mechanism is convenient in installation, usage and manufacture.

[0033] To be specific, as shown in FIGS. 5 and 9, to install the door plate 50 at the left-side installing surface 60, the user operates the first connecting element 23 to let it reach into the first cooperating hole 211 of the first moved element 21 and fasten at the first screw hole 411 of the shaft 41 simultaneously to connect the shaft 41 and the first moved element 21. Then the user operates the second connecting element 33, letting it fasten into the second screw hole 412 of the shaft 41 and detach from the second cooperating hole 311 of the second moved element 31. So, when the door plate 50 is being pushed, the door-fixing component 42 and the shaft 41 move up and down by cooperation between the first moved element 21 and the first guiding element 13. While the movable assembly 40 moves up, the second elastic element 32 is compressed. Alternatively, as shown in FIG. 6, to install the door plate 50 at the right-side installing surface 60, the user operates the second connecting element 33 to let it reach into the second cooperating hole 311 of the second moved element 31 and fasten at the second screw hole 412 of the shaft 41 simultaneously to connect the shaft 41 and the second moved element 31. Then detach the shaft 41 and the first moved element 21, so the door-fixing component 42 and the shaft 41 can move up and down by cooperation between the second moved element 31 and the second guiding element 14.

[0034] With reference to FIGS. 7 and 8, when the movable assembly 40 is moved, that is, when the door plate 50 is pushed so the movable assembly 40 is moved away from the original position, the cover 43 is lifted along with the movable assembly 40. The cover 43 shields the fixation component 16 of the fixation seat 10, the first guided assembly 20 and the second guided assembly 30, thus preventing external objects from entering the cover 43 to ensure operation fluency of the movable assembly 40. This further avoids an internal environment of the door plate 50 being seen from an external environment when the door plate 50 is pushed open, therefore increasing aesthetic appeal.

[0035] Besides, the fixation component 16, the first guiding element 13 and the second guiding element 14 can be one-piece formed or can be independent units. As shown in FIGS. 3 and 4, the first containing indentation 11 has at least one first position-limiting groove 111. The second containing indentation 12 has at least one second position-limiting groove 121. The first guiding element 13 has at least one first position-limiting protrusion 134 reaching into the at least one first position-limiting groove 111 to limit the first guiding element 13 in position. The second guiding element 14 has at least one second position-limiting protrusion 144 reaching into the at least one second position-limiting groove 121 to limit the second guiding element 14 in position. If the fixation component 16, the first guiding element 13 and the second guiding element 14 are independent units, then by cooperation between the position-limiting grooves and position-limiting protrusions, the first guiding element 13 does not pivot in the first containing indentation 11, and the second guiding element 14 does not pivot in the second containing indentation 12, thereby increasing operation stability of the movable assembly 40.

[0036] Furthermore, as shown in FIG. 2, the door-fixing component 42 comprises a foundation plate 422 and a clamping plate 423 mounted at the foundation plate 422. The movable assembly 40 comprises two pressing elements 44 and multiple pressing screws 45. The two pressing elements 44 are fixed at the foundation plate 422 with the multiple pressing screws 45. The two pressing elements 44 and the foundation plate 422 together clamp two ends of the shaft 41 to connect the shaft 41 and the door-fixing component 42. The foundation plate 422 and the clamping plate 423 together clamp the door plate 50 to install it on the door-fixing component 42.

[0037] To sum up, the first guided assembly 20 and the second guided assembly 30 are respectively guided by the first guiding element 13 and the second guiding element 14 to move away from each other or move back. Therefore, by connecting the shaft 41 with the first guided assembly 20 or the second guided assembly 30, the movable assembly 40 drives the door plate 50 up and down normally regardless that the fixation seat 10 is mounted at the left-side or right-side installing surface 60. So, the hinge mechanism can be used to install the door plate 50 to both the left-side and right-side installing surfaces 60, and therefore is convenient in installation, usage and manufacture.

[0038] Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and features of the invention, the disclosure is illustrative only. Changes may be made in the details, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
