Description

Technical Field

[0001] The present invention relates to a hinge assembly for furniture, particularly to a hinge assembly connecting furniture member.Background

[0002] Currently, the existing hinge structures primarily consist of a hinge head, a hinge arm, and a base, during installation, the hinge head and base are mounted onto the cabinet door and cabinet frame respectively, due to the single structure of adjusting the installation position of the hinge itself, it is difficult to meet usage requirements, consequently, the existing hinges demand high installation and positional accuracy, when the installation positions are deviated, the cabinet door and the cabinet frame cannot be installed at a predetermined position. This increases installation difficulty, prolongs work cycles, and reduces efficiency, therefore, some of the existing hinges are provided with an adjustment device, the hinge arm to be adjusted relative to the base in height adjustment in the up-down direction or the front-rear direction, or the left-right direction by adjustment device. However, in existing hinges, the process of adjusting the hinge arm solely in the up-down direction relative to the base and the process of adjusting solely in the left-right direction interfere with each other, for example, the height adjustment screw of the adjustment device only adjust the front end of the base upwards or downwards, when the front end of the base is raised to a specified position, the front end of the base is inclined towards the rear end and forms an angle with the hinge arm. In other words, during adjusting the height adjustment screw, the angle between the base and the hinge arm is changeable. this often leads to the cabinet door failing to close properly or close smoothly relative to the cabinet frame, such as a gap between the side where the cabinet door is closed and the cabinet frame, such as leaving a gap between one side of the closed door and the cabinet frame. So that it becomes necessary to adjust the front-rear adjustment screw(s) of the base and hinge arm to achieve the predetermined position between the cabinet door and cabinet frame. this situation makes it prone to incorrectly adjusting both the height and front-rear position of the base relative to the hinge arm, exacerbating the difficulty of the adjustment process.

[0003] In addition, Chinese Patent Publication No. CN204691509U discloses a buffer hinge with adjusting device, comprising a hinge cup, a rocking arm, a hinge base and a base assembly, the hinge cup, the rocking arm and the hinge base are sequentially hinged, the base assembly is mounted on the hinge base, the hinge base is provided with a height adjustment assembly capable of integrally controlling the parallel movement height of the base assembly relative to the hinge base, the height adjustment assembly runs through the hinge base and is fastened to the base assembly. Specifically, the height adjustment assembly includes a first height adjustment screw and a second height adjustment screw, and the first height adjustment screw and the second height adjustment screw are mounted on the hinge seat back and forth respectively. By means of the structural cooperation of the first height adjustment screw and the second height adjustment screw of the height adjustment assembly, the whole hinge base can be horizontal moved upwards or downwards to perform height adjustment, thereby ensuring that the hinge base can smoothly adjust the front and rear mounting positions relative to the base assembly on the horizontal plane. However, firstly, the height adjustment of the hinge base needs to be realized by a first height adjustment screw and a second height adjustment screw together, and the adjustment process is troublesome and difficult to adjust; generally, an operator first adjusts one of the adjustment screws and then adjusts the other adjustment screw, during the adjustment, the base assembly is actually rotated and swung forwards and backwards relative to the hinge base, and it is not achieved that the base assembly remains horizontal relative to the hinge base during the entire adjustment; secondly, when the height of the hinge base is adjusted, front and rear adjustment screws need to be operated, i. e. the height adjustment screws cannot be only adjusted to complete the height adjustment, and the height adjustment screws and the front and rear adjustment screws influence each other during the adjustment; thirdly, when the height of the hinge base is adjusted, front and rear adjustment screws on the hinge base need to be loosened first, the hinge base is prone to wrong movement in the front-rear direction, resulting in positional deviation in the front-rear direction, increasing the difficulty of adjustment, and making the height adjustment of the hinge base more troublesome, In addition, this solution does not produce positive effects while adding adjustment steps.

[0004] For another example, the Chinese Patent Publication No. CN 10701023 discloses a door hinge arm having quick adjustment and mounting functions, which comprises: an inner arm and an outer arm, the adjustment mechanism and a movement adjustment device are provided between the inner arm and the outer arm, the adjustment mechanism is used for adjusting the inclination angle between the outer arm and the inner arm. The movement adjustment device is used for installing and adjusting hinge arm which is used for forming a relative movement between the inner arm and the outer arm and for tilting an installation position of the adjusting door by automatically moving the outer arm forwards and backwards on the inner arm when an inclination angle between the outer arm and the inner arm changes. The hinge of the door can be adjusted by moving the adjustment device, so that the installation position of the door can be quickly adjusted. However, the adjustment mechanism changes the inclination angle between the outer arm and the inner arm during the adjustment, thus changing the minimum closing angle and the maximum opening angle of the hinge cup (the hinge head) relative to the base, i. e., changing the closing angle and the opening angle of the door on the furniture, which affects the user experience of opening and closing the door.Summary

[0005] In order to solve the technical problems in existing hinge that the hinge base related to the base assembly independent height adjustment and independent front-rear adjustment influence each other when adjusting, which resulting in high adjustment difficulty and trouble in adjustment, and affects the user experience when an angle of a switch door changes after height adjustment, the present invention disclosed a hinge assembly for furniture, comprising: a first main body and a hinge head, the hinge head is rotatably connected to the first main body, and the hinge head is configured to connect a second member; a base device, the base device is configured to connect a first member; the base device comprising at least a first adjustment assembly and at least a second adjustment assembly; wherein the first adjustment assembly is provided with at least a first adjustment part, when the first adjustment part is independently adjusted, the first main body can parallel lift only in an up-down direction relative to the first adjustment assembly, so that the first main body can parallel lift only in the up-down direction relative to at least a part of the base device; the second adjustment assembly is provided with a second adjustment part, when the second adjustment part is independently adjusted, the first main body can parallel move only in the front-rear direction relative to at least one part of the base devices. In some embodiments, a first positioning part is formed on the first adjustment assembly, a second positioning part cooperated with the first positioning part is formed on the first main body and / or the second adjustment assembly, the first positioning part and the second positioning part cooperate with each other to restrict the freedom of the first main body or the second adjustment assembly relative to the first adjustment assembly in the front-rear direction and the left-right direction, thus, when the first adjustment part is independently adjusted, so that the first main body can parallel lift only in the up-down direction relative to the first adjustment assembly.

[0006] In some embodiments, side surfaces of the first positioning part in the front-rear direction and the left-right direction match side surfaces of the second positioning part in the front-rear direction and the left-right direction, to restrict the freedom of the first main body or the second adjustment assembly relative to the first adjustment assembly in the front-rear direction and the left-right direction, so that the first main body can parallel lift only in the up-down direction relative to the first adjustment assembly.

[0007] In some embodiments, the first positioning part comprises the first adjustment part and a first abutting part, the second positioning part comprises a fixing part and a second abutting part, the first adjustment part is cylindrical, and the first adjustment part is rotatably arranged on the fixing part, and side surfaces of the first adjustment part along a front-rear direction and a left-right direction are in one-to-one correspondence with side faces of the fixing part along the front-rear direction and the left-right direction, to restrict the freedom of the first main body or the second adjustment assembly relative to the first adjustment assembly in the front-rear direction and the left-right direction; The first abutting part and the second abutting part abut against each other to restrict the first adjustment part from driving other components of the first adjustment part to rotate relative to the first main body or the second adjustment part to rotate relative to the first adjustment part when the first adjustment part is rotating.

[0008] The number of the fixing part is not limited. The number of the fixing part may be one or more, the first adjustment assembly may also be provided with one or more cylindrical shape parallel to the first adjustment part, the first positioning part comprises the cylindrical shape, and the cylindrical shape cooperates with other fixing parts to limit the degree of freedom of the first main body or the second adjustment assembly relative to the first adjustment assembly in the front-rear direction and the left-right direction.

[0009] Other technical solutions of the present invention are the same as the technical solutions recorded in claim 5 to claim 20, and are not further described herein.

Thus, a feature defined as "first", "second" may explicitly or implicitly include one or more of these features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0018] In the present invention, unless otherwise clearly specified and limited, the terms such as "installation", "connection", "connection" and "fixation" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection, or integrated; it can be mechanically connected or electrically connected; it can be directly connected or indirectly connected through an intermediary, and it can be the internal communication of two components or the interaction relationship between two components. Those of ordinary skill in the art can understand the specific meanings of the above terms in the present invention according to specific situations.

[0019] In the present invention, unless otherwise clearly specified and limited, a first feature being "on" or "under" a second feature include direct contact between the first and second features, and also include the first and second features not in direct contact but through another characteristic contact between them. Moreover, "above", "on" and "up" the first feature on the second feature include that the first feature is directly above and obliquely above the second feature, or simply means that the first feature is horizontally higher than the second feature. "Below", "beneath" and "under" the first feature to the second feature include that the first feature is directly below and obliquely below the second feature, or simply means that the first feature has a lower level than the second feature.

[0020] In the present invention, as well as «the Soft Close Hinge with Parallel Adjustment Device» as disclosed in Chinese Patent Publication No. CN204691509U and «the Door Hinge Arm with Quick Adjustment and Installation Function» as disclosed in Chinese Patent Publication No. CN10701023A have the technical problems as disclosed in the background art.

[0021] As shown in figures 1-40, the present embodiment discloses a hinge assembly for furniture, comprising a first main body 1 and a hinge head 2, the hinge head 2 is rotatably connected to the first main body1, and the hinge head 2 is configured to connect a second member 200; the base device 3 is configured to connect a first member 100 ; the base device 3 comprising at least a first adjustment assembly 31 and at least a second adjustment assembly 32 ; wherein the first adjustment assembly 31 is provided with at least a first adjustment part 33, when the first adjustment part 33 is independently adjusted, the first main body 1 can parallel lift only in an up-down direction relative to the first adjustment assembly 31, so that the first main body 1 can parallel lift only in the up-down direction relative to at least a part of the base device 3; the second adjustment assembly 32 is provided with a second adjustment part 34. When the second adjustment part 34 is independently adjusted, the first main body 1 can move only in the front-rear direction relative to at least one part of the base device 3.

[0022] Wherein the first member 100 and the second member 200 may be members boards of furniture products, and may be made of wood, plastic, metal, or other synthetic materials. The first member 100 may be, for example, a cabinet door of the cabinet, the second member 200 may be, for example, a cabinet side plate of the cabinet, and the first member 100 and the second member 200 rotate relative to each other via the hinge assembly of this embodiment.

[0023] It should be understood that, when the first adjustment part 33 is independently adjusted, the first main body 1 can parallel lift only in an up-down direction (the up-down direction may generally be a height direction) relative to the first adjustment assembly 31, That is, in the up-down direction, each part of the first main body 1 move the same height distance relative to the base device 3 in a unit time period, so that the first main body 1 does not incline or move in the left-right direction or the front-rear direction relative to the first adjustment assembly 31 and / or the second adjustment assembly 32, thus, it is ensured that the degree of freedom of the first main body 1 only in the up-down direction changes, and make sure the position adjustment of the first main body 1 in the front -rear direction relative to the base device 3. by the first adjustment part 33 adjusting the first main body 1 relative to the base device 3 to only parallel lift only in the up-down direction, and the second adjustment part 34 adjusting the first main body 1 relative to the base device 3 to only move in a front-rear direction, it is ensure that the first main body 1 does not affect or interfere with each other in the adjustment of the up-down direction and the front-rear direction, which reduce the adjustment difficulty, and improve the accuracy and convenience of position adjustment of the cabinet door relative to the cabinet body.

[0024] It should be noted that the term "independently adjust" briefly describes that the first main body 1 moves only in the up-down direction relative to the base device 3 when the first adjustment part 33 is adjusted, and the first main body 1 moves only in the front-rear direction relative to the base device 3 when the second adjustment part 34 is adjusted; It also indicates that when the first adjustment part 33 is adjusted, the first member 100 and the second member 200 are not have position movement in other directions except the up-down direction relative to the connecting surface of the base device 3; or, when the second adjustment part 34 is adjusted, the first member 100 and the second member 200 are not have position movement in other directions except the front-rear direction relative to the connecting surface of the base device 3;

[0025] It also indicates that when adjusting the first main body 1 moving in the up-down direction relative to the base device 3, just need to adjusting the first adjustment part 33, and no need to adjust the second adjustment part 34 or other parts; Alternatively, when adjusting the first main body 1 moving in the front-rear direction relative to the base device 3, just need to adjusting the first adjustment part 34, and no need to adjust the second adjustment part 33 or other parts .

[0026] In addition, "the first main body 1 does not incline or move in the left-right direction or the front-rear direction relative to the first adjustment assembly 31 and / or the second adjustment assembly 32" or "the first main body 1 does not move in the up-down direction or the left-right direction relative to the base device 3" is a description manner for describing the relative position of the front- rear, up-down positions, and does not indicate that there is absolutely no error or deviation; for example, in realistic production and installation, deviations frequently occur in the dimensions between parts. For example, when the first adjustment assembly 31 and the first main body 1 or the second adjustment assembly 32 are adjusted in the up-down direction, and one end point of the first adjustment assembly 31 and the other end point of the first main body 1 or the second adjustment assembly 32 are position movement by within 15 degrees in the front-rear or left-right direction due to adjustment, we still consider that this is a production and installation error, which still falls within the scope of protection of the present patent; The same applies during the adjustment of the second adjustment assembly 32.

[0027] In addition, it should be noted that, for example, as shown in Figure 1 to Figure 3, the up-down direction of the hinge assembly in this embodiment refers to a direction in which a side surface of the base device 3 connected to the first member 100 faces the base device 3, and when the first member 100 is a cabinet side plate and the second member 200 is a cabinet door, the up-down direction of the hinge assembly is a direction in which the cabinet door is adjusted left -right direction relative to the cabinet body (i. e. a left right direction in Figure 2 or Figure 3). the front-rear direction of the hinge assembly refers to a direction in which the hinged head 2 faces the first main body 1, when the first member 100 is a cabinet side plate and the second member 200 is a cabinet door, the front-rear direction of the hinge assembly is a direction in which the cabinet door is adjusted in the front-rear direction relative to the cabinet body. the left-right direction of the hinge assembly refers to a direction perpendicular to the up-down direction and the front-rear direction, and when the first member 100 is a cabinet side plate and the second member 200 is a cabinet door, the left-right direction of the hinge assembly is a direction in which the cabinet door is adjusted in up and down direction relative to the cabinet body.

[0028] The present embodiment does not limit the positional relationship among the first main body 1, the first adjustment assembly 31 and the second adjustment assembly 32. In some embodiments, as shown in Figure 4-25 and 35-40, at least one part of the first main body 1 is located above the base device 3, the first main body 1, the first adjustment assembly 31 or the second adjustment assemble 32 are connected from top to bottom, for example, the first main body 1, the first adjustment assembly 31 and the second adjustment assembly 32 are arranged sequentially from top to bottom, or the first main body 1, the second adjustment assembly 32 and the first adjustment assembly 31 are arranged sequentially from top to bottom. In some other embodiments, as shown in Figure 26 to Figure 29 and Figure 50 to Figure 52, at least one part of the base device 3 is located above the first main body 1, the first adjustment assembly 31 or the second adjustment assembly 32 and the first main body 1 are connected from top to bottom, for example, the first adjustment assembly 31, the second adjustment assembly 32 and the first main body 1 are arranged sequentially from top to bottom, or the second adjustment assembly 32, the first adjustment assembly 31, and the first main body 1 are arranged sequentially from top to bottom. In some other embodiments, as shown in Figure 30-31 and 33-34, at least one part of the base device 3 is located on a side of the first main body 1, the first adjustment assembly 31 or the second adjustment assembly 32 is connected to the first main body 1 along a left-right direction or a right-left direction, for example, the first adjustment assembly 31, the second adjustment assembly 32 and the first main body 1 are arranged sequentially from left to right, or the second adjustment assembly 32, the first adjustment assembly 31 and the first main body 1 are arranged sequentially from left to right.

[0029] In some embodiments, a first positioning part 4 is formed on the first adjustment assembly 31, a second positioning part 5 cooperated with the first positioning part 4 is formed on the first main body 1 and / or the second adjustment assembly 32, the first positioning part 4 and the second positioning part 5 cooperate with each other to restrict the freedom of the first main body 1 or the second adjustment assembly 32 relative to the first adjustment assembly 31 in the front-rear direction and the left-right direction, so that the first main body 1 can parallel lift only in the up-down direction relative to the first adjustment assembly 31. For example the second positioning part 5 may be located on the first main body 1, and the first adjustment assembly 31 and the first main body 1 can limit the degree of freedom of the first main body 1 in the front-rear direction and the left-right direction relative to the first adjustment assembly 31 by the cooperation of the first positioning part 4 and the second positioning part 5, when the first adjustment part 33 is independently adjusted, it is ensured that the first body 1 parallel lift only in the up-down direction relative to the first adjustment assembly 31. For another example, the second positioning part 5 may be located on the second adjustment assembly 32, and the first adjustment assembly 31 and the second adjustment assembly 32 can limit the degree of freedom of the second adjustment assembly 32 in the front-rear direction and the left-right direction relative to the first adjustment assembly 31 through cooperation between the first positioning part 4 and the second positioning part 5, when the first adjustment part 33 is independently adjusted, it is ensured that the second adjustment assembly 31 parallel lift only in the up-down direction relative to the first adjustment assembly 31,in this embodiments, the second adjustment assembly 32 is connected to the first main body 1, so that the first main body 1 can parallel lift only in the up-down direction relative to the first adjustment assembly 31.

Technical Field

[0001] The present invention relates to a hinge assembly for furniture, particularly to a hinge assembly connecting furniture member.Background

[0002] Currently, the existing hinge structures primarily consist of a hinge head, a hinge arm, and a base, during installation, the hinge head and base are mounted onto the cabinet door and cabinet frame respectively, due to the single structure of adjusting the installation position of the hinge itself, it is difficult to meet usage requirements, consequently, the existing hinges demand high installation and positional accuracy, when the installation positions are deviated, the cabinet door and the cabinet frame cannot be installed at a predetermined position. This increases installation difficulty, prolongs work cycles, and reduces efficiency, therefore, some of the existing hinges are provided with an adjustment device, the hinge arm to be adjusted relative to the base in height adjustment in the up-down direction or the front-rear direction, or the left-right direction by adjustment device. However, in existing hinges, the process of adjusting the hinge arm solely in the up-down direction relative to the base and the process of adjusting solely in the left-right direction interfere with each other, for example, the height adjustment screw of the adjustment device only adjust the front end of the base upwards or downwards, when the front end of the base is raised to a specified position, the front end of the base is inclined towards the rear end and forms an angle with the hinge arm. In other words, during adjusting the height adjustment screw, the angle between the base and the hinge arm is changeable. this often leads to the cabinet door failing to close properly or close smoothly relative to the cabinet frame, such as a gap between the side where the cabinet door is closed and the cabinet frame, such as leaving a gap between one side of the closed door and the cabinet frame. So that it becomes necessary to adjust the front-rear adjustment screw(s) of the base and hinge arm to achieve the predetermined position between the cabinet door and cabinet frame. this situation makes it prone to incorrectly adjusting both the height and front-rear position of the base relative to the hinge arm, exacerbating the difficulty of the adjustment process.

[0003] In addition, Chinese Patent Publication No. CN204691509U discloses a buffer hinge with adjusting device, comprising a hinge cup, a rocking arm, a hinge base and a base assembly, the hinge cup, the rocking arm and the hinge base are sequentially hinged, the base assembly is mounted on the hinge base, the hinge base is provided with a height adjustment assembly capable of integrally controlling the parallel movement height of the base assembly relative to the hinge base, the height adjustment assembly runs through the hinge base and is fastened to the base assembly. Specifically, the height adjustment assembly includes a first height adjustment screw and a second height adjustment screw, and the first height adjustment screw and the second height adjustment screw are mounted on the hinge seat back and forth respectively. By means of the structural cooperation of the first height adjustment screw and the second height adjustment screw of the height adjustment assembly, the whole hinge base can be horizontal moved upwards or downwards to perform height adjustment, thereby ensuring that the hinge base can smoothly adjust the front and rear mounting positions relative to the base assembly on the horizontal plane. However, firstly, the height adjustment of the hinge base needs to be realized by a first height adjustment screw and a second height adjustment screw together, and the adjustment process is troublesome and difficult to adjust; generally, an operator first adjusts one of the adjustment screws and then adjusts the other adjustment screw, during the adjustment, the base assembly is actually rotated and swung forwards and backwards relative to the hinge base, and it is not achieved that the base assembly remains horizontal relative to the hinge base during the entire adjustment; secondly, when the height of the hinge base is adjusted, front and rear adjustment screws need to be operated, i. e. the height adjustment screws cannot be only adjusted to complete the height adjustment, and the height adjustment screws and the front and rear adjustment screws influence each other during the adjustment; thirdly, when the height of the hinge base is adjusted, front and rear adjustment screws on the hinge base need to be loosened first, the hinge base is prone to wrong movement in the front-rear direction, resulting in positional deviation in the front-rear direction, increasing the difficulty of adjustment, and making the height adjustment of the hinge base more troublesome, In addition, this solution does not produce positive effects while adding adjustment steps.

[0004] For another example, the Chinese Patent Publication No. CN 10701023 discloses a door hinge arm having quick adjustment and mounting functions, which comprises: an inner arm and an outer arm, the adjustment mechanism and a movement adjustment device are provided between the inner arm and the outer arm, the adjustment mechanism is used for adjusting the inclination angle between the outer arm and the inner arm. The movement adjustment device is used for installing and adjusting hinge arm which is used for forming a relative movement between the inner arm and the outer arm and for tilting an installation position of the adjusting door by automatically moving the outer arm forwards and backwards on the inner arm when an inclination angle between the outer arm and the inner arm changes. The hinge of the door can be adjusted by moving the adjustment device, so that the installation position of the door can be quickly adjusted. However, the adjustment mechanism changes the inclination angle between the outer arm and the inner arm during the adjustment, thus changing the minimum closing angle and the maximum opening angle of the hinge cup (the hinge head) relative to the base, i. e., changing the closing angle and the opening angle of the door on the furniture, which affects the user experience of opening and closing the door.Summary

[0005] In order to solve the technical problems in existing hinge that the hinge base related to the base assembly independent height adjustment and independent front-rear adjustment influence each other when adjusting, which resulting in high adjustment difficulty and trouble in adjustment, and affects the user experience when an angle of a switch door changes after height adjustment, the present invention disclosed a hinge assembly for furniture, comprising: a first main body and a hinge head, the hinge head is rotatably connected to the first main body, and the hinge head is configured to connect a second member; a base device, the base device is configured to connect a first member; the base device comprising at least a first adjustment assembly and at least a second adjustment assembly; wherein the first adjustment assembly is provided with at least a first adjustment part, when the first adjustment part is independently adjusted, the first main body can parallel lift only in an up-down direction relative to the first adjustment assembly, so that the first main body can parallel lift only in the up-down direction relative to at least a part of the base device; the second adjustment assembly is provided with a second adjustment part, when the second adjustment part is independently adjusted, the first main body can parallel move only in the front-rear direction relative to at least one part of the base devices.

Thus, a feature defined as "first", "second" may explicitly or implicitly include one or more of these features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0018] In the present invention, unless otherwise clearly specified and limited, the terms such as "installation", "connection", "connection" and "fixation" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection, or integrated; it can be mechanically connected or electrically connected; it can be directly connected or indirectly connected through an intermediary, and it can be the internal communication of two components or the interaction relationship between two components. Those of ordinary skill in the art can understand the specific meanings of the above terms in the present invention according to specific situations.

[0019] In the present invention, unless otherwise clearly specified and limited, a first feature being "on" or "under" a second feature include direct contact between the first and second features, and also include the first and second features not in direct contact but through another characteristic contact between them. Moreover, "above", "on" and "up" the first feature on the second feature include that the first feature is directly above and obliquely above the second feature, or simply means that the first feature is horizontally higher than the second feature. "Below", "beneath" and "under" the first feature to the second feature include that the first feature is directly below and obliquely below the second feature, or simply means that the first feature has a lower level than the second feature.

[0020] In the present invention, as well as «the Soft Close Hinge with Parallel Adjustment Device» as disclosed in Chinese Patent Publication No. CN204691509U and «the Door Hinge Arm with Quick Adjustment and Installation Function» as disclosed in Chinese Patent Publication No. CN10701023A have the technical problems as disclosed in the background art.

[0021] As shown in figures 1-40, the present embodiment discloses a hinge assembly for furniture, comprising a first main body 1 and a hinge head 2, the hinge head 2 is rotatably connected to the first main body1, and the hinge head 2 is configured to connect a second member 200; the base device 3 is configured to connect a first member 100 ; the base device 3 comprising at least a first adjustment assembly 31 and at least a second adjustment assembly 32 ; wherein the first adjustment assembly 31 is provided with at least a first adjustment part 33, when the first adjustment part 33 is independently adjusted, the first main body 1 can parallel lift only in an up-down direction relative to the first adjustment assembly 31, so that the first main body 1 can parallel lift only in the up-down direction relative to at least a part of the base device 3; the second adjustment assembly 32 is provided with a second adjustment part 34. When the second adjustment part 34 is independently adjusted, the first main body 1 can move only in the front-rear direction relative to at least one part of the base device 3.

[0022] Wherein the first member 100 and the second member 200 may be members boards of furniture products, and may be made of wood, plastic, metal, or other synthetic materials. The first member 100 may be, for example, a cabinet door of the cabinet, the second member 200 may be, for example, a cabinet side plate of the cabinet, and the first member 100 and the second member 200 rotate relative to each other via the hinge assembly of this embodiment.

[0023] It should be understood that, when the first adjustment part 33 is independently adjusted, the first main body 1 can parallel lift only in an up-down direction (the up-down direction may generally be a height direction) relative to the first adjustment assembly 31, That is, in the up-down direction, each part of the first main body 1 move the same height distance relative to the base device 3 in a unit time period, so that the first main body 1 does not incline or move in the left-right direction or the front-rear direction relative to the first adjustment assembly 31 and / or the second adjustment assembly 32, thus, it is ensured that the degree of freedom of the first main body 1 only in the up-down direction changes, and make sure the position adjustment of the first main body 1 in the front -rear direction relative to the base device 3. by the first adjustment part 33 adjusting the first main body 1 relative to the base device 3 to only parallel lift only in the up-down direction, and the second adjustment part 34 adjusting the first main body 1 relative to the base device 3 to only move in a front-rear direction, it is ensure that the first main body 1 does not affect or interfere with each other in the adjustment of the up-down direction and the front-rear direction, which reduce the adjustment difficulty, and improve the accuracy and convenience of position adjustment of the cabinet door relative to the cabinet body.

[0024] It should be noted that the term "independently adjust" briefly describes that the first main body 1 moves only in the up-down direction relative to the base device 3 when the first adjustment part 33 is adjusted, and the first main body 1 moves only in the front-rear direction relative to the base device 3 when the second adjustment part 34 is adjusted; It also indicates that when the first adjustment part 33 is adjusted, the first member 100 and the second member 200 are not have position movement in other directions except the up-down direction relative to the connecting surface of the base device 3; or, when the second adjustment part 34 is adjusted, the first member 100 and the second member 200 are not have position movement in other directions except the front-rear direction relative to the connecting surface of the base device 3;

[0025] It also indicates that when adjusting the first main body 1 moving in the up-down direction relative to the base device 3, just need to adjusting the first adjustment part 33, and no need to adjust the second adjustment part 34 or other parts; Alternatively, when adjusting the first main body 1 moving in the front-rear direction relative to the base device 3, just need to adjusting the first adjustment part 34, and no need to adjust the second adjustment part 33 or other parts .

[0026] In addition, "the first main body 1 does not incline or move in the left-right direction or the front-rear direction relative to the first adjustment assembly 31 and / or the second adjustment assembly 32" or "the first main body 1 does not move in the up-down direction or the left-right direction relative to the base device 3" is a description manner for describing the relative position of the front- rear, up-down positions, and does not indicate that there is absolutely no error or deviation; for example, in realistic production and installation, deviations frequently occur in the dimensions between parts. For example, when the first adjustment assembly 31 and the first main body 1 or the second adjustment assembly 32 are adjusted in the up-down direction, and one end point of the first adjustment assembly 31 and the other end point of the first main body 1 or the second adjustment assembly 32 are position movement by within 15 degrees in the front-rear or left-right direction due to adjustment, we still consider that this is a production and installation error, which still falls within the scope of protection of the present patent; The same applies during the adjustment of the second adjustment assembly 32.

[0027] In addition, it should be noted that, for example, as shown in Figure 1 to Figure 3, the up-down direction of the hinge assembly in this embodiment refers to a direction in which a side surface of the base device 3 connected to the first member 100 faces the base device 3, and when the first member 100 is a cabinet side plate and the second member 200 is a cabinet door, the up-down direction of the hinge assembly is a direction in which the cabinet door is adjusted left -right direction relative to the cabinet body (i. e. a left right direction in Figure 2 or Figure 3). the front-rear direction of the hinge assembly refers to a direction in which the hinged head 2 faces the first main body 1, when the first member 100 is a cabinet side plate and the second member 200 is a cabinet door, the front-rear direction of the hinge assembly is a direction in which the cabinet door is adjusted in the front-rear direction relative to the cabinet body. the left-right direction of the hinge assembly refers to a direction perpendicular to the up-down direction and the front-rear direction, and when the first member 100 is a cabinet side plate and the second member 200 is a cabinet door, the left-right direction of the hinge assembly is a direction in which the cabinet door is adjusted in up and down direction relative to the cabinet body.

[0028] The present embodiment does not limit the positional relationship among the first main body 1, the first adjustment assembly 31 and the second adjustment assembly 32. In some embodiments, as shown in Figure 4-25 and 35-40, at least one part of the first main body 1 is located above the base device 3, the first main body 1, the first adjustment assembly 31 or the second adjustment assemble 32 are connected from top to bottom, for example, the first main body 1, the first adjustment assembly 31 and the second adjustment assembly 32 are arranged sequentially from top to bottom, or the first main body 1, the second adjustment assembly 32 and the first adjustment assembly 31 are arranged sequentially from top to bottom. In some other embodiments, as shown in Figure 26 to Figure 29 and Figure 50 to Figure 52, at least one part of the base device 3 is located above the first main body 1, the first adjustment assembly 31 or the second adjustment assembly 32 and the first main body 1 are connected from top to bottom, for example, the first adjustment assembly 31, the second adjustment assembly 32 and the first main body 1 are arranged sequentially from top to bottom, or the second adjustment assembly 32, the first adjustment assembly 31, and the first main body 1 are arranged sequentially from top to bottom. In some other embodiments, as shown in Figure 30-31 and 33-34, at least one part of the base device 3 is located on a side of the first main body 1, the first adjustment assembly 31 or the second adjustment assembly 32 is connected to the first main body 1 along a left-right direction or a right-left direction, for example, the first adjustment assembly 31, the second adjustment assembly 32 and the first main body 1 are arranged sequentially from left to right, or the second adjustment assembly 32, the first adjustment assembly 31 and the first main body 1 are arranged sequentially from left to right.

[0029] In some embodiments, a first positioning part 4 is formed on the first adjustment assembly 31, a second positioning part 5 cooperated with the first positioning part 4 is formed on the first main body 1 and / or the second adjustment assembly 32, the first positioning part 4 and the second positioning part 5 cooperate with each other to restrict the freedom of the first main body 1 or the second adjustment assembly 32 relative to the first adjustment assembly 31 in the front-rear direction and the left-right direction, so that the first main body 1 can parallel lift only in the up-down direction relative to the first adjustment assembly 31. For example the second positioning part 5 may be located on the first main body 1, and the first adjustment assembly 31 and the first main body 1 can limit the degree of freedom of the first main body 1 in the front-rear direction and the left-right direction relative to the first adjustment assembly 31 by the cooperation of the first positioning part 4 and the second positioning part 5, when the first adjustment part 33 is independently adjusted, it is ensured that the first body 1 parallel lift only in the up-down direction relative to the first adjustment assembly 31. For another example, the second positioning part 5 may be located on the second adjustment assembly 32, and the first adjustment assembly 31 and the second adjustment assembly 32 can limit the degree of freedom of the second adjustment assembly 32 in the front-rear direction and the left-right direction relative to the first adjustment assembly 31 through cooperation between the first positioning part 4 and the second positioning part 5, when the first adjustment part 33 is independently adjusted, it is ensured that the second adjustment assembly 31 parallel lift only in the up-down direction relative to the first adjustment assembly 31,in this embodiments, the second adjustment assembly 32 is connected to the first main body 1, so that the first main body 1 can parallel lift only in the up-down direction relative to the first adjustment assembly 31.
