Definitions
- the present invention relates to a refrigeration appliance, and in particular, to a refrigeration appliance having a door hinge assembly, such as a refrigerator, a wine cooler or a freezer.
- CN102365515A discloses an adjustable hinge assembly for a pivot door, including a pivot shaft fixed to a hinge plate, an adjusting part sleeved on the pivot shaft and a locking member for maintaining the position of the adjusting part along the pivot shaft, where the pivot shaft has a thread portion and defines a rotation axis of the door, and the adjusting part has an inner thread which is rotatable along the thread portion of the pivot shaft to adjust the height of the door.
- the locking member extends through one of multiple recesses arranged at an outer periphery of the adjusting part, and it is necessary to remove the locking member when the adjusting part is rotated.
- the adjusting part is always next to the bottom of the door, if an operator uses a tool to grip the adjusting part to rotate the adjusting part, the tool always interferes with a member above the adjusting part, which may increase the difficulty of adjusting the height of the door, and such inconvenience is particularly evident when the adjusting part is located at the bottom of the refrigerator.
- An objective of the present invention is to provide a refrigeration appliance capable of helping to reduce the difficulty of adjusting the height of the door.
- the refrigeration appliance includes a main body, a door, and a hinge assembly connecting the door to the main body, where the hinge assembly includes a hinge bracket with an end fixed to the main body, a hinge shaft connected to the hinge bracket and defining a rotation axis of the door, and an adjusting part for adjusting the height of the door relative to the main body; characterized by further including a lift member sleeved on the hinge shaft and connected to the adjusting part in a threaded connection manner, and the adjusting part is rotatable along a first direction to drive the lift member to move upwards along the hinge shaft and support the door to move upwards.
- the adjusting part rotates to drive the lift member which is connected to the adjusting part in a threaded connection manner so as to move the door upwards, and the adjusting part can be maintained (at least substantially held) at an original position, which helps to reduce probability of interference between the adjusting part and the bottom of the door, thereby helping to reduce the difficulty of adjusting the height of the door.
- the adjusting part sits on a support surface parallel to the hinge bracket when adjusting the height of the door
- the adjusting part sits on the hinge bracket. This not only helps to simplify the structure of the hinge assembly, but also helps to increase a height adjustment range between the bottom of the door and the hinge bracket.
- the lift member when the adjusting part rotates along a second direction opposite to the first direction, the lift member is movable downwards until the lift member directly sits on the hinge bracket.
- the adjusting part when the lift member sits on the hinge bracket, the adjusting part is capable of being rotated and moving upwards to be suspended.
- the thread between the lift member and the adjusting part no longer needs to bear the weight of the door. This provides a possibility, i.e., when it is unnecessary to adjust the height of the door, for example, during transport of the refrigeration appliance, the adjusting part may be in a suspended/resting state, to avoid damage to the connection thread between the adjusting part and the lift member caused by possible up and down vibration of the door.
- the adjusting part has an inner thread
- the lift member is inserted into the adjusting part and has an outer thread connected to the inner thread in a threaded connection manner.
- the lift member includes a cylinder portion inserted into the adjusting part, and a platform portion having a cross-sectional area greater than that of the cylinder portion, and the platform portion forms an upper end surface of the lift member. This helps to increase the support area of the lift member for bearing the weight of the door.
- an anti-rotation structure for preventing the lift member from rotating with respect to the hinge shaft.
- the anti-rotation structure may include a groove formed by one of the lift member and the hinge shaft and extending in a direction of the rotation axis, and a protruding portion formed by the other one of the lift member and the hinge shaft and protruding from an inner peripheral surface or outer peripheral surface of the same and extending into the groove.
- the refrigeration appliance may include a door closing unit between the bottom of the door and the lift member.
- the door closing unit includes an upper door closing part fixed to the bottom of the door and a lower door closing part connected to the lift member in a manner of being not rotatable to the top member, wherein the upper door closing part and the lower door closing part each have a cam surface and the pair of cam surfaces contact with each other face to face.
- the refrigeration appliance includes a stopper structure for preventing the lift member from continuing to move upwards after moving upwards to a highest position. This particularly helps to avoid the situation where a user/worker excessively rotates the adjusting part such that the lift member and the adjusting part exit the threaded connection or even fall off.
- the stopper structure includes a first stopper portion connected to the lift member and a second stopper portion formed in the adjusting part, where the first stopper portion and the second stopper portion butt against each other at the highest position to prevent the lift member from continuing to move upwards, so as to avoid in a simple and reliable manner that the adjusting part is separated from the lift member.
- the first stopper portion is connected to a lower end of the lift member.
- the first stopper portion is formed by a stopper ring sleeved on the lift member or is integrally formed on the lift member.
- the adjusting part is hollow and includes an adjusting portion having an inner thread and a base portion connected to the adjusting portion, where an inner diameter of the base portion is greater than that of the adjusting portion to form a connection surface for connecting the base portion and an inner peripheral surface of the adjusting portion, and the second stop portion is formed by the connection surface. Integrally forming the second stop portion directly on an inner wall surface of the adjusting part helps to reduce parts of the hinge assembly, thereby helping to simplify the assembling of the hinge assembly.
- the adjusting part step adjusts the height of the door. This helps the user/worker operating the adjusting part to feel the adjusted height more clearly.
- one of the adjusting part and the hinge bracket is provided with a plurality of concave portions surrounding the hinge shaft and disposed at intervals, and the other one of the adjusting part and the hinge bracket is provided with at least one convex portion, where the convex portion is adapted to be at least partially received in any one of the concave portions.

If the adjusting part 3 continues to be rotated along the first direction, the adjusting part 3 remains sitting on the hinge bracket 2 (i.e., keeps contact with the hinge bracket) and drives, through coordination between the first thread portion 31 and the second thread portion 41, the lift member 4 to move upwards along the hinge shaft 8 to push the door 102 to move upwards. In the process, a distance between the lift member 4 and the hinge bracket 2 gradually increases, and the door 102 is gradually lifted.
- the lift member 4 moves upwards to the first stopper portion 5 which moves up with the lift member 4 to contact with the second stopper portion 34 of the adjusting part 3, the lift member 4 cannot continue to move up, and the adjusting part 3 that sits on the hinge bracket 2 cannot continue to rotate in the first direction. As shown in FIG. 5 , the lift member 4 moves upwards to the maximum height. The lift member 4 and the door 102 are adjusted to a highest position in the door adjustment range decided by the adjusting part 3.
- the adjusting part 3 that sits on the hinge bracket 2 may be rotated along a second direction (e.g., counterclockwise) opposite to the first direction, and the lift member 4 is driven to move down along the hinge shaft 8, so that the door 102 supported by the lift member 4 moves downwards together.
- a second direction e.g., counterclockwise
- the adjusting part 3 When the lift member 4 directly sits on the hinge bracket 2, if the adjusting part 3 continues to be rotated in the second direction, the adjusting part can move upwards along the second thread portion 41 of the lift member 4 to form spacing with the hinge bracket 2 and hence be suspended, and the lift member 4 remains sitting on the hinge bracket 2. At this time, the adjusting part 3 is in a resting state, and the lift member 4 remains in the lowest position. As stated above, by rotating the adjusting part 3 in the first direction, the suspended adjusting part 3 can be moved downwards along the lift member 4 until the adjusting part contacts with the hinge bracket 2.
- the adjusting part 3 when the height of the door 102 is adjusted, the adjusting part 3 is always in contact with the hinge bracket 2, to drive the lift member 4 to move up or down in the direction of the rotation axis X; moreover, after the lift member 4 reaches the lowest position, the lift member 4 may sit on the hinge bracket 2, and if the adjusting part 3 is rotated along a predetermined direction, the adjusting part 3 may move upwards along the lift member 4 which stands still to the suspended state without bearing the weight of the door 102, thereby avoiding, for example, damage to threads of the adjusting part 3 and the lift member 4 during transport; furthermore, when the lift member 4 moves upwards to the first stopper portion 5 and butts against the second stopper portion 34, the lift member 4 cannot continue to move upwards, thereby avoiding the situation where the adjusting part 3 is rotated excessively to cause the adjusting part 3 and the lift member 4 to fall off.
- the hinge assembly 1 also may be constructed such that the adjusting part 3 adjusts the height of the door 102 from stage to stage according to a predetermined step.

- the adjusting part 3 also may be provided with one concave portion 25 or two convex portions 35 distributed symmetrically about the central axis of the adjusting part 3.
- each of the convex portions 35 moves out of an original concave portion 25 and rotates along the upper surface of the hinge bracket 2, until the convex portion falls into a concave portion 25 adjacent to the original concave portion 25, and this will give an obvious feeling of indication to a user/worker operating the adjusting part.

Abstract
Description
- The present invention relates to a refrigeration appliance, and in particular, to a refrigeration appliance having a door hinge assembly, such as a refrigerator, a wine cooler or a freezer.
- The height of a door hinged to a main body of a refrigeration appliance relative to the main body may change, and it is known that the height of the door relative to the main body is adjusted using a door hinge assembly of a height adjusting mechanism. For example,
CN102365515A discloses an adjustable hinge assembly for a pivot door, including a pivot shaft fixed to a hinge plate, an adjusting part sleeved on the pivot shaft and a locking member for maintaining the position of the adjusting part along the pivot shaft, where the pivot shaft has a thread portion and defines a rotation axis of the door, and the adjusting part has an inner thread which is rotatable along the thread portion of the pivot shaft to adjust the height of the door. During rotation, the adjusting part moves up and down, to move the door upwards or downwards. The locking member extends through one of multiple recesses arranged at an outer periphery of the adjusting part, and it is necessary to remove the locking member when the adjusting part is rotated. - As the adjusting part is always next to the bottom of the door, if an operator uses a tool to grip the adjusting part to rotate the adjusting part, the tool always interferes with a member above the adjusting part, which may increase the difficulty of adjusting the height of the door, and such inconvenience is particularly evident when the adjusting part is located at the bottom of the refrigerator.
- An objective of the present invention is to provide a refrigeration appliance capable of helping to reduce the difficulty of adjusting the height of the door.
- Thus, one aspect of the present invention relates to a refrigeration appliance. The refrigeration appliance includes a main body, a door, and a hinge assembly connecting the door to the main body, where the hinge assembly includes a hinge bracket with an end fixed to the main body, a hinge shaft connected to the hinge bracket and defining a rotation axis of the door, and an adjusting part for adjusting the height of the door relative to the main body; characterized by further including a lift member sleeved on the hinge shaft and connected to the adjusting part in a threaded connection manner, and the adjusting part is rotatable along a first direction to drive the lift member to move upwards along the hinge shaft and support the door to move upwards.
- When it is necessary to increase the height of the door relative to the main body, the adjusting part rotates to drive the lift member which is connected to the adjusting part in a threaded connection manner so as to move the door upwards, and the adjusting part can be maintained (at least substantially held) at an original position, which helps to reduce probability of interference between the adjusting part and the bottom of the door, thereby helping to reduce the difficulty of adjusting the height of the door.
- The above objective can be achieved through the features in the independent claim. Exemplary embodiments of the present invention are subject matters of the accompanying drawings, the specification and the dependent claims.
- Although it is possible that the adjusting part sits on a support surface parallel to the hinge bracket when adjusting the height of the door, according to a particularly exemplary embodiment of the present invention, when adjusting the height of the door, the adjusting part sits on the hinge bracket. This not only helps to simplify the structure of the hinge assembly, but also helps to increase a height adjustment range between the bottom of the door and the hinge bracket.
- According to an exemplary embodiment of the present invention, when the adjusting part rotates along a second direction opposite to the first direction, the lift member is movable downwards until the lift member directly sits on the hinge bracket.
- According to an exemplary embodiment of the present invention, when the lift member sits on the hinge bracket, the adjusting part is capable of being rotated and moving upwards to be suspended. As the lift member supporting the door can be directly supported by the hinge bracket, the thread between the lift member and the adjusting part no longer needs to bear the weight of the door. This provides a possibility, i.e., when it is unnecessary to adjust the height of the door, for example, during transport of the refrigeration appliance, the adjusting part may be in a suspended/resting state, to avoid damage to the connection thread between the adjusting part and the lift member caused by possible up and down vibration of the door.
- According to an exemplary embodiment of the present invention, the adjusting part has an inner thread, and the lift member is inserted into the adjusting part and has an outer thread connected to the inner thread in a threaded connection manner.
- According to an exemplary embodiment of the present invention, the lift member includes a cylinder portion inserted into the adjusting part, and a platform portion having a cross-sectional area greater than that of the cylinder portion, and the platform portion forms an upper end surface of the lift member. This helps to increase the support area of the lift member for bearing the weight of the door.
- According to an exemplary embodiment of the present invention, an anti-rotation structure for preventing the lift member from rotating with respect to the hinge shaft is included. Preferably, the anti-rotation structure may include a groove formed by one of the lift member and the hinge shaft and extending in a direction of the rotation axis, and a protruding portion formed by the other one of the lift member and the hinge shaft and protruding from an inner peripheral surface or outer peripheral surface of the same and extending into the groove. Thus, the lift member is connected to the hinge shaft in a non-rotatable manner without adding any extra member, helping to guide the lift member to move along the hinge shaft in a vertical direction.
- According to an exemplary embodiment of the present invention, the refrigeration appliance may include a door closing unit between the bottom of the door and the lift member.
- According to an exemplary embodiment of the present invention, the door closing unit includes an upper door closing part fixed to the bottom of the door and a lower door closing part connected to the lift member in a manner of being not rotatable to the top member, wherein the upper door closing part and the lower door closing part each have a cam surface and the pair of cam surfaces contact with each other face to face.
- According to an exemplary embodiment of the present invention, the refrigeration appliance includes a stopper structure for preventing the lift member from continuing to move upwards after moving upwards to a highest position. This particularly helps to avoid the situation where a user/worker excessively rotates the adjusting part such that the lift member and the adjusting part exit the threaded connection or even fall off.
- According to an exemplary embodiment of the present invention, when the lift member moves upwards to the highest position, all threads of the adjusting part and the thread of the lift member maintain the threaded connection. This helps to avoid the situation where the adjusting part and the lift member are damaged as the weight of the door is borne by only part of the threads between the adjusting part and the lift member.
- According to an exemplary embodiment of the present invention, the stopper structure includes a first stopper portion connected to the lift member and a second stopper portion formed in the adjusting part, where the first stopper portion and the second stopper portion butt against each other at the highest position to prevent the lift member from continuing to move upwards, so as to avoid in a simple and reliable manner that the adjusting part is separated from the lift member.
- According to an exemplary embodiment of the present invention, the first stopper portion is connected to a lower end of the lift member.
- According to an exemplary embodiment of the present invention, the first stopper portion is formed by a stopper ring sleeved on the lift member or is integrally formed on the lift member.
- According to an exemplary embodiment of the present invention, the adjusting part is hollow and includes an adjusting portion having an inner thread and a base portion connected to the adjusting portion, where an inner diameter of the base portion is greater than that of the adjusting portion to form a connection surface for connecting the base portion and an inner peripheral surface of the adjusting portion, and the second stop portion is formed by the connection surface. Integrally forming the second stop portion directly on an inner wall surface of the adjusting part helps to reduce parts of the hinge assembly, thereby helping to simplify the assembling of the hinge assembly.
- According to an exemplary embodiment of the present invention, the adjusting part step adjusts the height of the door. This helps the user/worker operating the adjusting part to feel the adjusted height more clearly.
- According to an exemplary embodiment of the present invention, one of the adjusting part and the hinge bracket is provided with a plurality of concave portions surrounding the hinge shaft and disposed at intervals, and the other one of the adjusting part and the hinge bracket is provided with at least one convex portion, where the convex portion is adapted to be at least partially received in any one of the concave portions. Such a scheme not only prevents the adjusting part from accidentally rotating relative to the hinge bracket, but also can be easily used to form means for determining adjustment steps of the adjusting part by appropriately laying out concave and convex portions.

The hinge assembly 1 is configured such that heights of thecorresponding doors 102 and 102' relative to themain body 101 can be adjusted respectively. The hinge assembly 1 is described below in detail by taking the hinge assembly 1 connected to thedoor 102 as an example. -
FIG. 2 is a schematic partial perspective view of a door and a hinge assembly of a refrigeration appliance assembled together according to an exemplary embodiment of the present invention; andFIG. 3 is a schematic exploded view of a hinge assembly according to an exemplary embodiment of the present invention. Referring toFIG. 2 andFIG. 3 in combination withFIG. 1 , the hinge assembly 1 includes ahinge bracket 2 with an end fixed to themain body 101, ahinge shaft 8 fixed to thehinge bracket 2 and defining a rotation axis X of thedoor 102, and an adjustingpart 3 for adjusting the height of thedoor 102 relative to themain body 101. - The
hinge bracket 2 includes amounting portion 21 fixed to themain body 101. Themounting portion 21 may be provided with a plurality offixing holes 22 to allow a suitable fixing part (not shown) to pass through the mounting portion so as to fix the hinge bracket to themain body 101. The fixing part may be a screw. In this embodiment, the mountingportion 21 is connected to the bottom face of themain body 101. In an alternative embodiment, by suitably changing the shape of the hinge bracket, the hinge bracket also may be fixed to a front surface of the main body, which is especially applied to the situation where the hinge assembly is a middle hinge. - The
hinge bracket 2 includes a supportingportion 23 extending forward from the mountingportion 21. The supportingportion 23 is perpendicular to the front surface of themain body 101. In this embodiment, the supportingportion 23 and the mounting portion are integrally formed, and are substantially plate-shaped. - The hinge assembly 1 includes a
hinge shaft 8 fixed to thehinge bracket 2, and thehinge shaft 8 defines a rotation axis of thedoor 102. In this embodiment, thehinge shaft 8 is unmovable relative to themain body 101. - The
hinge shaft 8 is fixed to the supportingportion 23 and extends upright from the supportingportion 23. During rotation of thedoor 102, thehinge shaft 8 is unmovable relative to the supportingportion 23. In this embodiment, thehinge shaft 8 and the supportingportion 23 are assembled together after being manufactured respectively. Specifically, thehinge shaft 8 passes through ashaft fixing hole 24 on the supportingportion 23 and is welded to the supportingportion 23. - The
hinge shaft 8 may include a pair ofshaft fixing holes 24 symmetric about a central axis in the longitudinal direction thereof to allow thehinge shaft 8 to simultaneously adapt to connection with thedoors 102 and 102'. - In an alternative embodiment, the
hinge shaft 8 and the supportingportion 23 also may form an integral member. - In this embodiment, the
hinge shaft 8 is a hollow cylinder, and has acentral hole 80. In an alternative embodiment, the hinge shaft also may be a solid cylinder. - An upper end of the
hinge shaft 8 extends into thedoor 102, so that thedoor 102 can rotate around the rotation axis defined by thehinge shaft 8. - The adjusting
part 3 is sleeved outside thehinge shaft 8, and is rotatable around thehinge shaft 8 to adjust the height of thedoor 102 relative to themain body 101. The adjustingpart 3 has afirst thread portion 31 which is an inner thread. An outer peripheral surface of the adjustingpart 3 can be constructed like a screw nut to adapt to operations of standard tools such as wrenches. - The adjusting
part 3 is hollow, including an adjustingportion 32 with afirst thread portion 31 formed on an inner peripheral surface. In an exemplary embodiment, the adjustingpart 3 may further include a lower end connected to the adjustingportion 32 and abase portion 33 whose inner diameter is greater than that of the adjustingportion 32, so that a connection surface for connecting inner peripheral surfaces of thebase portion 33 and the adjustingportion 32 is formed therebetween, and asecond stopper portion 34 is formed on the connection surface to coordinate with the followingfirst stopper portion 5. - In this embodiment, the
second stopper portion 34 is substantially an annular wall, which may be substantially perpendicular to the rotation axis X. The inner surface of thebase portion 33 may be smooth. - The hinge assembly 1 includes a
lift member 4 in connected to the adjustingpart 3 in a threaded connection manner. Thelift member 4 has a throughhole 40 running through thelift member 4 in a direction of the rotation axis X to sleeve thehinge shaft 8, and has asecond thread portion 41 which is an outer thread coordinating with thefirst thread portion 31. Thesecond thread portion 41 is formed by ahollow cylinder portion 42 of thelift member 4. In a radial direction, thecylinder portion 42 is inserted into the adjustingpart 3 and is thus located between thehinge shaft 8 and the adjustingpart 3. - The
door 102 is supported by an upper end surface of thelift member 4. Thelift member 4 also may have a platform portion 43 for increasing the area of the upper end surface of thelift member 4. - The
lift member 4 is connected to thehinge shaft 8 in a manner of being not rotatable relative to thehinge shaft 8. In this embodiment, an anti-rotation structure for preventing thelift member 4 from rotating with respect to thehinge shaft 8 includes agroove 81 formed by thehinge shaft 8 and extending in a direction of the rotation axis X, and a protrudingportion 44 formed by the lift member and protruding from an inner peripheral surface of the throughhole 40 and extending into thegroove 81. The protrudingportion 44 may extend along the entire axial length of thelift member 4. - In an alternative embodiment, the anti-rotation structure also may include a groove formed by the lift member and extending in a direction of the rotation axis X, and a protruding portion protruding from an outer peripheral surface of the hinge shaft and extending into the groove.
- The hinge assembly 1 also may include a
first stopper portion 5 connected to a lower end of thelift member 4. Thefirst stopper portion 5 protrudes outwards from an outer peripheral surface of thelift member 4 and is overlapped with thesecond stopper portion 34 in the direction of the rotation axis X. Thus, thelift member 4 having thefirst stopper portion 5 cannot enter into the hole of the adjustingportion 32 of the adjustingpart 3 but is movable vertically in the hole of thebase portion 3 of the adjustingpart 3. - In an exemplary embodiment, the
first stopper portion 5 is formed by a stopper ring sleeved on thelift member 4. The lower end of thecylinder portion 41 may form a circle of retaininggroove 45 recessed in the radial direction, and the stopper ring is sandwiched in the retaininggroove 45 so as to prevent the stopper ring from moving in the direction of the rotation axis X. - In assembling, the adjusting
part 3 is first screwed onto thelift member 4, and it would be best if the end of thelift member 4 extends out of the adjustingpart 3, so as to connect thefirst stopper portion 5 to the lower end of thelift member 4. Then, the assembled adjustingpart 3, thelift member 4 and thefirst stopper portion 4 are sleeved on thehinge shaft 8. At this time, thelift member 4 can be directly supported on thehinge bracket 2, and spacing may be even formed between the adjustingpart 3 and thehinge bracket 2. - The hinge assembly 1 may further include a door closing unit 6 between the
lift member 4 and the bottom of thedoor 102. The door closing unit 6 may include an upperdoor closing part 61 fixed to the bottom of thedoor 102 in an unmovable manner and a lowerdoor closing part 62 connected to the upper end of thelift member 4, where the upperdoor closing part 61 and the lowerdoor closing part 62 each have a cam surface and the cam surfaces contact with each other face to face. - The lower
door closing part 62 is fixed to thelift member 4 in a manner of being not rotatable relative to thelift member 4. In an exemplary embodiment, holes may be respectively formed on the lowerdoor closing part 62 and theplatform portion 42 of thelift member 4, and a fixing part (not shown, for example, a screw) passes through the two holes to fix the lowerdoor closing part 62 and thelift member 4 together. In an alternative embodiment, one or more protruding portions spaced apart and protruding toward opposite sides also may be formed on one of thelift member 4 and the lowerdoor closing part 62, and a corresponding pit/hole is formed on the other one of thelift member 4 and the lowerdoor closing part 62 so as to form a plug-in connection, thereby preventing thelift member 4 from rotating with respect to the lowerdoor closing part 62. - In an alternative embodiment, it is likely that the lower
door closing part 62 is integrally formed on thelift member 4. - The upper
door closing part 61 may further include asleeve portion 611 sleeved on thehinge shaft 8. - When the hinge assembly 1 is connected to the
door 102 and themain body 101, thelift member 4 can sit on thehinge bracket 2 to be directly supported by thehinge bracket 2, and spacing may be formed between the adjustingpart 3 and thehinge bracket 2 so that the adjustingpart 3 is in a resting state. As the weight of thedoor 102 is directly supported by thehinge bracket 2 at this time, rather than being supported by thefirst thread portion 31 and thesecond thread portion 42 connected in a threaded connection manner, such a situation is particularly conductive to reducing probability of damage to thefirst thread portion 31 and thesecond thread portion 42 caused by possible up and down vibration of thedoor 102 during transport of therefrigeration appliance 100. - When it is necessary to adjust the height of the
door 102 relative to themain body 101, the adjustingpart 3 may be rotated along a first direction (e.g., clockwise), and the adjustingpart 3 moves downwards along thelift member 4 until the adjustingpart 3 contacts with thehinge bracket 2, as shown inFIG. 4 . In the process, thelift member 4 stands still, the height of thedoor 102 supported by thelift member 4 relative to themain body 101 is also unchanged, and at this time, thelift member 4 and thedoor 102 are both at the lowest position in a door adjustment range decided by the adjustingpart 3. - After the adjusting
part 3 sits on thehinge bracket 2, the adjustingpart 3 is in an adjustment state capable of adjusting the height of thedoor 102. If the adjustingpart 3 continues to be rotated along the first direction, the adjustingpart 3 remains sitting on the hinge bracket 2 (i.e., keeps contact with the hinge bracket) and drives, through coordination between thefirst thread portion 31 and thesecond thread portion 41, thelift member 4 to move upwards along thehinge shaft 8 to push thedoor 102 to move upwards. In the process, a distance between thelift member 4 and thehinge bracket 2 gradually increases, and thedoor 102 is gradually lifted. - When the
lift member 4 moves upwards to thefirst stopper portion 5 which moves up with thelift member 4 to contact with thesecond stopper portion 34 of the adjustingpart 3, thelift member 4 cannot continue to move up, and the adjustingpart 3 that sits on thehinge bracket 2 cannot continue to rotate in the first direction. As shown inFIG. 5 , thelift member 4 moves upwards to the maximum height. Thelift member 4 and thedoor 102 are adjusted to a highest position in the door adjustment range decided by the adjustingpart 3. - Preferably, when the
lift member 4 moves upwards to the maximum height limit, all threads of thefirst thread portion 31 and the thread of thesecond thread portion 41 still maintain the threaded connection. - When it is necessary to lower the height of the
door 102, the adjustingpart 3 that sits on thehinge bracket 2 may be rotated along a second direction (e.g., counterclockwise) opposite to the first direction, and thelift member 4 is driven to move down along thehinge shaft 8, so that thedoor 102 supported by thelift member 4 moves downwards together. When the lower end of thelift member 4 directly contacts with thehinge bracket 2, thelift member 4 and thedoor 102 supported by thelift member 4 reach the lowest position. - When the
lift member 4 directly sits on thehinge bracket 2, if the adjustingpart 3 continues to be rotated in the second direction, the adjusting part can move upwards along thesecond thread portion 41 of thelift member 4 to form spacing with thehinge bracket 2 and hence be suspended, and thelift member 4 remains sitting on thehinge bracket 2. At this time, the adjustingpart 3 is in a resting state, and thelift member 4 remains in the lowest position. As stated above, by rotating the adjustingpart 3 in the first direction, the suspended adjustingpart 3 can be moved downwards along thelift member 4 until the adjusting part contacts with thehinge bracket 2. - According to an embodiment of the present invention, when the height of the
door 102 is adjusted, the adjustingpart 3 is always in contact with thehinge bracket 2, to drive thelift member 4 to move up or down in the direction of the rotation axis X; moreover, after thelift member 4 reaches the lowest position, thelift member 4 may sit on thehinge bracket 2, and if the adjustingpart 3 is rotated along a predetermined direction, the adjustingpart 3 may move upwards along thelift member 4 which stands still to the suspended state without bearing the weight of thedoor 102, thereby avoiding, for example, damage to threads of the adjustingpart 3 and thelift member 4 during transport; furthermore, when thelift member 4 moves upwards to thefirst stopper portion 5 and butts against thesecond stopper portion 34, thelift member 4 cannot continue to move upwards, thereby avoiding the situation where the adjustingpart 3 is rotated excessively to cause the adjustingpart 3 and thelift member 4 to fall off. - The hinge assembly 1 also may be constructed such that the adjusting
part 3 adjusts the height of thedoor 102 from stage to stage according to a predetermined step. In an exemplary embodiment, referring toFIG. 3 to FIG. 6 , the upper surface of thehinge bracket 2 has a plurality ofconcave portions 25 surrounding theshaft fixing hole 24 and disposed at intervals. Theconcave portions 25 can be distributed in a common concentric ring. The lower end surface of the adjustingpart 3 is provided with a plurality ofconvex portions 35, and each of theconvex portions 35 can be at least partially received in any one of theconcave portions 25. In an alternative embodiment, the adjustingpart 3 also may be provided with oneconcave portion 25 or twoconvex portions 35 distributed symmetrically about the central axis of the adjustingpart 3. - When the adjusting
part 3 is adjusted, each of theconvex portions 35 moves out of an originalconcave portion 25 and rotates along the upper surface of thehinge bracket 2, until the convex portion falls into aconcave portion 25 adjacent to the originalconcave portion 25, and this will give an obvious feeling of indication to a user/worker operating the adjusting part. - The
concave portions 25 are distributed at an equal interval. In the embodiment shown inFIG. 3 , each of the shaft fixing holes 24 corresponds to sixconcave portions 25 distributed at an equal interval. - As shown in
FIG. 6 , it would be best if each of theconvex portions 35 is of an inverted cone shape, and the cone top is chamfered for transition. Theconcave portion 25 may also be constructed as an inverted cone that adapts to matching with theconvex portion 35. - In addition, with the plug-in connection between the
convex portions 35 and theconcave portions 25, the adjustingpart 3 can adjust the height of thedoor 102 from stage to stage according to a predetermined amplitude; in the event that no large rotation force is applied to the adjustingpart 3, the adjustingpart 3 does not rotate, that is to say, accidental rotation of the adjustingpart 3 can be avoided. - In an alternative embodiment, the concave portions also may be formed on the lower end surface of the adjusting part, and the convex portions are formed on the hinge bracket.
- In the above embodiments, the
first stopper portion 5 is assembled on thelift member 4 as a separate component. However, in an alternative embodiment, it is likely that the first stopper portion is integrally formed on thelift member 4. - Various embodiments of individual parts described in combination with
FIG. 1 to FIG. 6 can be combined in any given manner, so as to achieve the advantages of the present invention. In addition, the present invention is not limited to the illustrated embodiments, and generally, other means except the illustrated means may also be used as long as the means can achieve the same effect.
