Description

Hinge assembly for furniture Technical Field

[0001] The present invention relates to a hinge assembly for furniture, in particular to a hinge assembly for furniture. Background Art

[0002] At present, the structure of the existing hinge mainly includes a hinge head, a hinge arm and a base. The installer installs the hinge head and the base on the cabinet door and the cabinet body respectively. The hinge arm and / or the base are provided with an adjustment device that allows the hinge arm to be adjusted left and right relative to the base. The left and right adjustment device, for example, uses a fastening hole, which is used to pass through a fastener to fix the base on the surface of the cabinet door or cabinet body; when the fastening hole is a circular hole that matches the fastener, in order to achieve left and right adjustment, the base plate where the fastening hole is located needs to cooperate with other components of the base and the left and right adjustment device to achieve left and right movement of other components of the base relative to the base, thereby achieving left and right movement of the hinge arm relative to the base plate (or cabinet door or cabinet body). In this case, the manufacturing cost is relatively high; when the fastening hole is a strip hole extending left and right, the fastening hole and the fastener can cooperate as a left and right adjustment device, that is, when the fastener is in a preset state, the base plate can move left and right relative to the fastener and the cabinet body (or cabinet door), and when the fastener is in a locked state, the base plate is fixed to the cabinet body or cabinet door.

[0003] In order to further improve the aesthetics of the hinge, a straight base hinge began to appear, that is, the existing straight base hinge has a fastening hole located within the projection of the hinge arm along the projection direction perpendicular to the hinge arm, that is, the fastening hole is located directly below the hinge arm; when the fastening hole is a strip hole extending in the left-right direction and there is only one of it, the load-bearing of the cabinet door depends solely on the binding force between the fastener and the strip hole. When the cabinet door is heavy and is used frequently, it is easy to cause insufficient binding force between the fastener and the strip hole, resulting in the cabinet door moving down; when the fastening hole of the straight base hinge is a strip hole extending in the left-right direction and there are two or more of them, two or more adjustment holes are arranged side by side in the front-to-back direction, that is, two or more fasteners are lined up in a row in the front-to-back direction. In this case, compared with the fasteners being arranged in a cross relative to the front-to-back direction, it is easy to cause insufficient binding force between the fastener and the strip hole, resulting in the cabinet door moving down.

[0004] Summary of the Invention

[0005] In order to solve the problem of insufficient binding force between the fastener and the strip hole, which causes the cabinet door to move downward, in the conventional straight base hinge when the fastening hole is a strip hole, the present invention provides a hinge assembly for furniture, comprising:

[0006] A hinge assembly for furniture, comprising:

[0007] A first body and a hinge head, wherein the hinge head is rotatably connected to the first body and is used to connect to a second component;

[0008] A base device, the base device is provided on the surface of the first component and is used to connect the first component;

[0009] The base device includes at least one adjustment hole, which is a strip-shaped hole extending in the left-right direction and is located within the projection of the first body along a projection direction perpendicular to the first component;

[0010] The adjustment hole is used for a fastener to fix the base device on the first member, and when the fastener is in a preset state, the base device can move in the left and right directions relative to the fastener;

[0011] The upper surface of the peripheral wall of the adjustment hole has a transverse stripe extending forward and backward, and when the fastener is in a locked state, the transverse stripe is used to prevent the base device from moving in the left and right directions relative to the fastener; and / or,

[0012] The base device has a protrusion extending downward. When the fastener is in a locked state, the protrusion and the first component are engaged with each other to prevent the base device from moving in the left-right direction relative to the fastener.

[0013] In some embodiments, the number of the adjustment holes is at least two.

[0014] In some embodiments, at least two of the adjustment holes are arranged along the front-to-back direction.

[0015] In some embodiments, the adjustment hole has an upper opening and a lower opening arranged in sequence along the up and down directions, the cross-sectional area of ​​the upper opening is larger than the cross-sectional area of ​​the lower opening, the adjustment hole forms an inclined surface between the upper opening and the lower opening, and the transverse stripe portion is arranged on the inclined surface.

[0016] In some embodiments, the protrusion and the lower end of the inclined surface are transitionally connected.

[0017] In some embodiments, the fastener includes a mounting portion and a boss, the mounting portion is mounted on the first component through the adjustment hole, and when the fastener is in a locked state, the lower end of the boss presses against the transverse portion to prevent the base device from moving in the left and right directions relative to the fastener.

[0018] In some embodiments, the protrusion is in the shape of an inverted triangle, a cone, or an inverted trapezoid.

[0019] In some embodiments, when the fastener is in a locked state, the protrusion forms a matching recess on the surface of the first component, and the protrusion and the recess combine to prevent the base device from moving in the left-right direction relative to the fastener.

[0020] In some embodiments, when the fastener is in a locked state, the protrusion breaks through the surface of the first component to enter the interior of the first component, thereby preventing the base device from moving in the left-right direction relative to the fastener.

[0021] In some embodiments, the first main body includes a connecting plate, a left side plate and a right side plate, and the connecting plate, the left side plate and the right side plate are enclosed to form a mounting groove. Along the projection direction perpendicular to the connecting plate, the distance between the left and right edges of the base device and the edge of the internal projection of the mounting groove is less than 3 mm.

[0022] Compared with the prior art, the hinge assembly of furniture of the present invention has at least the following beneficial effects:

[0023] Since the fastening hole is a strip hole extending in the left and right directions, the fastening hole is not a circular hole, so the straight base hinge saves the left and right adjustment parts and the parts that match the bottom plate, saving costs; without increasing costs, it overcomes the problem that the left and right adjustment strip holes of the straight base hinge easily cause insufficient bonding force between the fasteners and the strip holes, resulting in the cabinet door moving down.

[0038] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0039] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0040] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0041] In the prior art, problems such as those described in the background art occur.

[0042] In order to solve the problems of the above-mentioned background technology, as shown in Figures 1 to 11, an embodiment of the present invention discloses a hinge assembly for furniture, including a first body 1, a hinge head 2 and a base device 3. The hinge head 2 is rotatably connected to the first body 1 and is used to connect the second component 200; the base device 3 is provided on the surface of the first component 100 and is used to connect the first component 100; the base device 3 includes at least one adjustment hole 31, which is a strip-shaped hole extending in the left-right direction. In the projection direction perpendicular to the first component 100, the adjustment hole 31 is located within the projection of the first body 1; the adjustment hole 31 is used for fasteners 4 to fix the base device 3 on the first component 100. When the fastener 4 is in a preset state, the base device 3 can move in the left and right directions relative to the fastener 4; the upper surface of the peripheral wall of the adjustment hole 31 has a transverse groove portion 311 extending forward and backward, and when the fastener 4 is in a locked state, the transverse groove portion 311 is used to prevent the base device 3 from moving in the left and right directions relative to the fastener 4; and / or, a downwardly extending protrusion 312 is provided on the base device 3, and when the fastener 4 is in a locked state, the protrusion 312 and the first component 100 are locked to prevent the base device 3 from moving in the left and right directions relative to the fastener 4.

[0043] The first component 100 and the second component 200 can each be a component panel of a furniture product, and can be made of wood, plastic, metal, or other synthetic materials. The first component 100 can be, for example, a cabinet door, and the second component 200 can be, for example, a cabinet side panel. The first component 100 and the second component 200 can achieve relative rotation via the hinge assembly of this embodiment.

[0044] It is understandable that, in some embodiments, as shown in Figures 9 to 11, a transverse groove portion 311 is provided on the upper surface of the peripheral wall of the adjustment hole 31 of the base device 3. The fastener 4 is, for example, a screw or a bolt. The transverse groove portion 311 forms an integrated structure with the base device 3, and is specifically prepared by processes such as casting, cutting, or mold manufacturing. The transverse groove portion 311 can be composed of a plurality of ribs, bosses, or convex strips. When the fastener 4 locks the base device 3 on the first component 100, the end of the fastener 4 and the transverse groove portion 311 cooperate with each other to abut against each other, and the transverse groove portion 311 is used to generate a resistance to the fastener 4 that hinders movement in the left and right directions, thereby preventing the base device 3 from moving in the left and right directions on the first component 100. This overcomes the problem that the left and right adjustment strip holes of the one-line base hinge easily cause insufficient bonding force between the fastener 4 and the strip hole, resulting in the cabinet door moving down.

[0045] In other embodiments, the base assembly 3 is provided with a downwardly extending protrusion 312. When the fastener 4 is locked on the first member 100 (fastener 4 is in the locked state), at least a portion of the protrusion 312 is embedded in the interior of the first member 100, interlocking the protrusion 312 and the first member 100, thereby preventing the base assembly 3 from moving left and right on the first member 100. This overcomes the problem of the left and right adjustment strip holes of the straight base hinge, which can easily lead to insufficient engagement between the fastener 4 and the strip holes, causing the cabinet door to move downward.

[0046] In other embodiments, a transverse stripe portion 311 is provided on the upper surface of the peripheral wall of the adjustment hole 31 of the base device 3 , and a protrusion 312 extending downward is provided on the base device 3 .

[0047] It should be noted that, for example, as shown in Figures 1, 5, and 6, the up-down direction of the hinge assembly of this embodiment 1 refers to the direction in which the side surface where the base device 3 is connected to the first component 100 is facing the base device 3. When the first component 100 is a cabinet side panel and the second component 200 is a cabinet door, the up-down direction of the hinge assembly is the direction in which the cabinet door is adjusted left and right relative to the cabinet body. The front-to-back direction of the hinge assembly refers to the direction in which the hinge head 2 is facing the first main body 1. When the first component 100 is a cabinet side panel and the second component 200 is a cabinet door, the front-to-back direction of the hinge assembly is the direction in which the cabinet door is adjusted left and right relative to the cabinet body. The left-right direction of the hinge assembly refers to a direction that is perpendicular to both the up-down direction and the front-to-back direction. When the first component 100 is a cabinet side panel and the second component 200 is a cabinet door, the left-to-right direction of the hinge assembly is the direction in which the cabinet door is adjusted up and down relative to the cabinet body.

[0048] In the present invention, the number of adjustment holes 31 is one or more. For example, in some embodiments, the number of adjustment holes 31 is at least two. Furthermore, at least two adjustment holes 31 are provided on the base device 3 along the front-to-back direction. Specifically, the number of adjustment holes 31 is two, and the two adjustment holes 31 are provided at both ends of the base device 3 along the front-to-back direction.

[0049] In some embodiments, as shown in Figures 9 to 11, the adjustment hole 31 has an upper opening 313 and a lower opening 314 arranged in sequence along the vertical direction. The cross-sectional area of ​​the upper opening 313 is larger than the cross-sectional area of ​​the lower opening 314. The adjustment hole 31 forms an inclined surface 315 between the upper opening 313 and the lower opening 314, and the transverse ridge 311 is provided on the inclined surface 315. The bar-shaped adjustment hole 31 is trumpet-shaped. After the fastener 4 passes through the adjustment hole 31, it is fastened to the first component 100, facilitating the complete placement of the fastener 4 within the adjustment hole 31. The inclined surface 315 of the adjustment hole 31 acts as a limiter or positioner for the fastener 4, so that the fastener 4 and the peripheral sidewalls of the adjustment hole 31 abut against each other to fasten the base device 3 to the first component 100.

[0050] In some embodiments, when a downwardly extending protrusion 312 is provided on the base device 3, the protrusion 312 and the lower end of the inclined surface 315 are transitionally connected, so that the base device 3 can easily form an integrated structure with the protrusion 312, thereby improving the overall structural strength, and preventing the base device 3 from moving in the left and right directions on the first component 100 by the protrusion 312 and the first component 100 being locked together.

[0051] In some embodiments, the fastener 4 includes a mounting portion 41 and a boss 42. The mounting portion 41 is mounted on the first component 100 through the adjustment hole 31. When the fastener 4 is in a locked state, the lower end of the boss 42 abuts against the transverse groove 311 to prevent the base assembly 3 from moving left and right relative to the fastener 4. The mounting portion 41, for example, has an external thread structure. The boss 42 has a larger cross-sectional area than the mounting portion 41. The boss 42 abuts against the peripheral sidewall of the adjustment hole 31 to provide a position limit, thereby securing the base assembly 3 to the first component 100. The fastener 4 is specifically, for example, a screw or bolt.

[0052] In some embodiments, as shown in FIG3 , when a downwardly extending protrusion 312 is provided on the base device 3, the protrusion 312 is in the shape of an inverted triangle, a cone, or an inverted trapezoid, and the end of the protrusion 312 is sharp. When the fastener 4 is in a locked state, the protrusion 312 can be self-drilled and embedded in the interior of the first component 100 so that the protrusion 312 and the first component 100 are tightly engaged with each other.

[0053] In some embodiments, when the fastener 4 is in the locked state, the protrusion 312 forms a matching recess on the surface of the first member 100. The protrusion 312 and the recess combine to prevent the base assembly 3 from moving in the left-right direction relative to the fastener 4. The protrusion 312 and the recess on the first member 100 engage each other through a concave-convex fit, thereby fastening the base assembly 3 to the first member 100 and preventing the base assembly 3 from moving in the left-right direction on the first member 100.

[0054] In some embodiments, when the fastener 4 is in a locked state, the protrusion 312 breaks through the surface of the first component 100 to enter the interior of the first component 100, and at least a portion of the protrusion 312 is located inside the first component 100, thereby preventing the base device 3 from moving in the left and right directions relative to the fastener 4.

[0055] In some embodiments, as shown in Figures 5 to 8, the first main body 1 includes a connecting plate 11, a left side plate 12 and a right side plate 13, the left side plate 12 is connected to the left side of the connecting plate 11 and extends downward, the right side plate 13 is connected to the right side of the connecting plate 11 and extends downward, the connecting plate 11, the left side plate 12 and the right side plate 13 are surrounded to form a mounting groove 14, and along the projection direction perpendicular to the connecting plate 11, the distance between the left and right edges of the base device 3 and the edge of the internal projection of the mounting groove 14 is less than 3 mm. It is understandable that the left and right sides of the base device 3 can be located within the internal projection of the mounting groove 14, or the left and right edges of the base device 3 can slightly protrude from the internal projection of the mounting groove 14. For example, the distance between the left and right edges of the base device 3 and the internal projection of the mounting groove 14 is 0.5 mm, 1 mm, 1.5 mm, 2 mm, 3 mm, etc. When the hinge assembly is observed in the projection direction perpendicular to the connecting plate 11, the left and right edge portions of the base device 3 are exposed in a very small area or almost no area on the first body 1. It is difficult for the user to observe the base device 3 from the outside or only a very small part of the base device 3 can be seen, so as to improve the aesthetics. At the same time, compared with the existing hinge, the base device 3 of the present invention is smaller in volume and area, saving overall material usage, reducing process difficulty, and thus reducing manufacturing costs. In addition, the base device 3 with a smaller area can save space and improve space utilization.

[0056] In some embodiments, the base device 3 is located within the internal projection of the mounting groove 14 along the projection direction perpendicular to the connecting plate 11. Since the area of ​​the base device 3 is smaller than the area of ​​the connecting plate 11 along the projection direction perpendicular to the connecting plate 11, so that the base device 3 is located within the internal projection of the mounting groove 14, it is difficult for the user to observe the base device 3 from the outside or only a very small part of the base device 3 can be seen, thereby improving the aesthetics; and when the user observes the hinge in the direction perpendicular to the connecting plate 11, the base device 3 is in a completely invisible state, giving the impression that there is no base device hinge, making the hinge more beautiful. At the same time, compared with the existing base device, the base device 3 of the present invention is smaller in volume and area, saving overall material usage, reducing process difficulty, and thus reducing manufacturing costs. In addition, the base device 3 with a smaller area can save space and improve space utilization.

[0057] In some embodiments, the lower ends of the left side panel 12 and / or the right side panel 13 form a straight line. The lower ends of the left side panel 12 and / or the right side panel 13 are flush with the lower end of the base assembly 3, or the base assembly 3 is entirely located within the mounting groove 14. When viewing the hinge assembly from a direction perpendicular to the left side panel 12 or the right side panel 13, the user cannot see the base assembly 3. In other words, the lower ends of the left side panel 12 and / or the right side panel 13 form a straight line, thereby improving the aesthetics of the hinge assembly.
