[0025] like Figure 1 As shown, a furniture assembly according to an embodiment of the present invention includes a cabinet 20, and the cabinet 20 is provided with a plurality of drawers arranged vertically and / or horizontally (arranged laterally). For example, a first drawer 22a, a second drawer 22b, a third drawer 22c, and a fourth drawer 22d. These drawers 22a, 22b, 22c, 22d can be displaced longitudinally relative to the cabinet 20.

[0026] like Figure 2 As shown, the cabinet 20 is provided with a plurality of slide rail assemblies which can be used to carry the above-mentioned drawers respectively. For example, a first slide rail assembly 24a, a second slide rail assembly 24b, a third slide rail assembly 24c and a fourth slide rail assembly 24d, these slide rail assemblies 24a, 24b, 24c, 24d have substantially the same structural configuration, and each slide rail assembly includes a first rail 26 and a second rail 28 which can be longitudinally displaced relative to the first rail 26. In this embodiment, the X-axis direction is the longitudinal direction (or the length direction or displacement direction of the slide rail), the Y-axis direction is the transverse direction (or the lateral direction of the slide rail), and the Z-axis direction is the vertical direction (or the height direction of the slide rail).

[0027] Preferably, each slide rail assembly further includes a third rail 30 movably mounted between the first rail 26 and the second rail 28 to extend the displacement stroke of the second rail 28 relative to the first rail 26 .

[0028] Preferably, the first rails 26 of the slide rail assemblies 24a, 24b, 24c, 24d are mounted (eg, fixed) to the cabinet 20, and the second rails 28 of the slide rail assemblies 24a, 24b, 24c, 24d can respectively carry the drawers 22a, 22b, 22c, 22d ( Figure 2 Only the drawer 22d is shown for illustration), which helps the drawers 22a, 22b, 22c, 22d to be more smoothly folded or opened relative to the cabinet 20 through the second rails 28 of the slide rail assemblies 24a, 24b, 24c, 24d. For example, when the second rail 28 of the first slide rail assembly 24a is folded relative to the first rail 26, the first drawer 22a can be folded relative to the cabinet 20; or, for example, when the second rail 28 of the fourth slide rail assembly 24d is opened relative to the first rail 26, the fourth drawer 22d can be opened relative to the cabinet 20.

[0029] The furniture assembly further includes at least one interlocking lock set, for example, a first interlocking lock set 32a, a second interlocking lock set 32b, a third interlocking lock set 32c, and a fourth interlocking lock set 32d. These interlocking lock sets 32a, 32b, 32c, 32d are linked to each other, and each interlocking lock set has substantially the same structural configuration. Through the interlocking lock set, the furniture assembly can have an interlocking lock function, so that when one of the drawers 22a, 22b, 22c, 22d is opened relative to the cabinet 20, the rest of the drawers cannot be opened.

[0030] Further, each interlocking lock set 32a, 32b, 32c or 32d includes a first accessory 34 and a second accessory 36. The first accessory 34 is used to be set on the cabinet 20, and the second accessory 36 is used to be set on the drawer (22a, 22b, 22c or 22d).

The working portion 76 of the working piece 48 can be used in conjunction with the actuating portion 74 of the second accessory 36. The working portion 76 is, for example, a protrusion, but the implementation is not limited thereto.

[0040] Preferably, the actuating portion 74 of the second accessory 36 and the working portion 76 of the working piece 48 have different extension heights. For example, one of the actuating portion 74 of the second accessory 36 and the working portion 76 of the working piece 48 has a first extension height h1, and the other of the actuating portion 74 of the second accessory 36 and the working portion 76 of the working piece 48 has a second extension height h2, and the first extension height h1 is greater than the second extension height h2 (e.g., Figure 4 Here, it is taken as an example that the actuating portion 74 of the second accessory 36 has the first extension height h1, and the working portion 76 of the working piece 48 has the second extension height h2, but the implementation is not limited thereto.

[0041] like Figure 4 and Figure 5 As shown, the first accessory 34 is used to be installed on the cabinet 20 (such as Figure 5When the second accessory 36 is relative to the above drawer (22a, 22b, 22c or 22d), Figure 5 Taking the drawer 22a as an example, when the drawer 22a is installed at any installation position within the range of the predetermined spacing G, such as a first installation position K1, the first wall 70a of the second accessory 36 and the first wall 42a of the first accessory 34 are close to each other, and the second wall 70b of the second accessory 36 and the second wall 42b of the first accessory 34 are far away from each other.

[0042] Preferably, the first accessory 34 and the second accessory 36 can be limited relative to each other. For example, one of the first wall 70a of the second accessory 36 and the first wall 42a of the first accessory 34 is provided with a first limiting feature 82, and the first limiting feature 82 can block the other of the first wall 70a of the second accessory 36 and the first wall 42a of the first accessory 34, so that the second accessory 36 can only be located at the first installation position K1 within the range of the predetermined spacing G relative to the first accessory 34, for example, a highest position (such as Figure 5 shown).

[0043] Preferably, the second accessory 36 further includes a first predetermined portion 78, and the auxiliary component 50 further includes a second predetermined portion 80 that can be used in conjunction with the first predetermined portion 78.

Figure 8 and Fig. 9 As shown) moves to a second auxiliary position Q2 (as shown Fig.10 As shown), the first locking member 52 and the second locking member 54 of the interlocking lock mechanism 40 are maintained in a locked position.

[0056] In the process of the auxiliary member 50 moving from the first auxiliary position Q1 to the second auxiliary position Q2, the auxiliary member 50 can contact each other through the first guide portion 86 and the first auxiliary guide feature 88, so that the first locking member 52 moves from the unlocking position J1 (such as Figure 8 As shown) moves in a height direction U to the locking position J2 (as shown Fig.10 As shown), and the auxiliary member 50 is in the second auxiliary position Q2 to support the first locking member 52, so as to keep the first locking member 52 in the locked position J2 (as shown). Fig.10 On the other hand, when the auxiliary member 50 is in the second auxiliary position Q2, the auxiliary member 50 presses the second locking member 54 to keep the second locking member 54 in the locked position J2' (as shown in FIG. Fig.10 In addition, since the working member 48 is swung from the first working position M1 to the second working position M2, the working portion 76 of the working member 48 can be released from the actuating portion 74 of the second accessory 36 (as shown in FIG.

[0058] like Fig.11 As shown, when the second accessory 36 of the first chain lock kit 32a (or the first drawer 22a) is in the extended position E relative to the first accessory 34 (or the cabinet 20), and the auxiliary component 50 in the second auxiliary position Q2 keeps the first lock component 52 and the second lock component 54 in the locked positions J2 and J2', respectively, the second accessories 36 of the remaining chain lock kits (such as the second chain lock kit 32b and the third chain lock kit 32c) cannot be opened in the predetermined direction D1 relative to the first accessory 34. In other words, the remaining drawers (such as the above-mentioned second drawer 22b and the third drawer 22c) cannot be opened relative to the cabinet 20.

[0059] Further, the two ends of the first rod body 94 are respectively connected to the first locking piece 52 of the first chain lock set 32a and the second locking piece 96 of the second chain lock set 32b; in addition, when the second accessory 36 of the second chain lock set 32b is in the retracted position R relative to the first accessory 34, the second accessory 36 of the second chain lock set 32b corresponds to the working piece 108 (the working part 110) through its actuating part 107; when the first locking piece 52 of the first chain lock set 32a is maintained at the locked position J2 (this part can cooperate with Fig.10 ), the second locking member 96 (the second auxiliary guide feature 112) of the second chain lock assembly 32b can block the movable path of the auxiliary member 114 (the second guide portion 116) of the second chain lock assembly 32b, so as to prevent the second accessory 36 of the second chain lock assembly 32b from driving the auxiliary member 114 to move in the predetermined direction D1 through the working member 108 of the second chain lock assembly 32b, thereby preventing the second accessory 36 of the second chain lock assembly 32b from opening from the folded position R to the predetermined direction D1 relative to the first accessory 34.

[0060] Similarly, the two ends of the second rod body 98 are respectively connected to the second locking piece 54 of the first ring lock set 32a and the first locking piece 100 of the third ring lock set 32c; in addition, when the second accessory 36 of the third chain lock set 34c is in the retracted position R relative to the first accessory 34, the second accessory 36 of the third chain lock set 32c corresponds to the working piece 118 (the working part 120) through its actuating part 117; when the second locking piece 54 of the first chain lock set 32a is maintained at the locked position J2' (this part can cooperate with Fig.10), the first locking member 100 (the first auxiliary guide feature 122) of the third chain lock assembly 32c can block the moving path of the auxiliary member 124 (the first guide portion 126) of the third chain lock assembly 32c, so as to prevent the second accessory 36 of the third chain lock assembly 32c from driving the auxiliary member 124 to move in the predetermined direction D1 through the working member 118 of the third chain lock assembly 32c, thereby preventing the second accessory 36 of the third chain lock assembly 32c from opening from the folded position R to the predetermined direction D1 relative to the first accessory 34.

[0061] It can be seen from this that when the second accessory 36 of one of these chain lock kits (for example, the first chain lock kit 32a) is opened relative to the first accessory 34, the auxiliary part 50 is in the second auxiliary position Q2, so that the chain lock mechanism 40 is maintained in the locked state to provide a chain lock function to prevent the second accessories 36 of the remaining chain lock kits from being opened relative to the first accessory 34.

[0062] like Fig.11 , Fig.10 and Figure 8 As shown, when the interlocking function is to be released, the auxiliary member 50 of the first interlocking assembly 32a must be moved from the second auxiliary position Q2 (such as Fig.11 and Fig.10 As shown) returns to the first auxiliary position Q1 (as shown Figure 8 Further, when the first drawer 22a is moved from the extended position E (as shown in FIG. Fig.11 and Fig.10 When the auxiliary member 50 moves from the second auxiliary position Q2 (as shown) to another predetermined direction D2 (such as the folding direction) toward the folded position R, the auxiliary member 50 moves from the second auxiliary position Q2 (as shown) to another predetermined direction D2 (such as the folding direction) toward the folded position R. Fig.11 and Fig.10 ) is brought back to the first auxiliary position Q1 (as shown) by the second accessory 36. Figure 8 For example, the second accessory 36 contacts the second predetermined portion 80 of the auxiliary member 50 through the first predetermined portion 78, and can bring the auxiliary member 50 back to the first auxiliary position Q1 (as shown in FIG. Figure 8 As shown), the auxiliary member 50 no longer supports the first locking member 52, so that the first locking member 52 is moved from the locking position J2 (as shown Fig.11 and Fig.10 As shown) back to the unlocked position J1 (as shown Figure 8 ), and the auxiliary member 50 no longer presses the second locking member 54 (as shown Figure 8In addition, the guide section 102 of the second accessory 36 of the first chain lock assembly 32a can be used to guide the working portion 76 of the working piece 48, so that the supporting feature 64 of the working piece 48 is released from the bent portion 62 of the base 46, so that the working piece 48 is swung back to the first working position M1 from the second working position M2, and the second accessory 36 of the first chain lock assembly 32a returns to the retracted position R (as shown in FIG. Figure 8 shown).

[0063] like Fig.12 , Fig.13 and Fig.14 As shown, when the second accessory 36 is installed at the second installation position K2 within the range of the predetermined distance G relative to the first drawer 22a, the actuating portion 74 of the second accessory 36 corresponds to the working portion 76 of the working member 48 (such as Fig.12 and Fig.13 Alternatively, the actuating portion 74 of the second accessory 36 and the working portion 76 of the working member 48 have different extension heights (such as Figure 4 or Figure 6 The first extension height h1 and the second extension height h2 shown in the figure are used to allow the second accessory 36 to be installed at at least two different installation positions relative to the first drawer 22a (here, the second installation position K2 different from the first installation position K1 is taken as an example). When the actuating portion 74 of the second accessory 36 corresponds to the working portion 76 of the working member 48 (such as Fig.12 and Fig.13 shown).

[0064] Further, when the second accessory 36 is installed at the second installation position K2 within the range of the predetermined distance relative to the first drawer 22a, and the first drawer 22a ( Figure 12 to Figure 14 Only the second accessory 36 is shown to indicate that the first drawer 22a) is relative to the cabinet 20 ( Figure 12 to Figure 14 Only the first accessory 34 is shown to indicate that the cabinet 20 is moved from the closed position R (eg Fig.12 When the first drawer 22a moves toward the extended position E in the predetermined direction D1, the actuating portion 74 of the second accessory 36 can contact the working portion 76 of the working member 48 (as shown in FIG. Fig.13 ), for driving the working member 48 to move from the first working position M1 to the second working position M2 (as shown in FIG. Fig.14 ), wherein the support feature 64 of the work piece 48 is engaged with the bent portion 62 of the base 46, so that the work piece 48 is deflected at an angle to be in the second working position M2, and the auxiliary member 50 is driven from the first auxiliary position Q1 (as shown in FIG. Fig.12 and Fig.13 As shown) moves to the second auxiliary position Q2 (as shown Fig.14 As shown), the first locking member 52 and the second locking member 54 of the interlocking lock mechanism 40 are used to keep them in the locked position.

[0065] In the process of the auxiliary member 50 moving from the first auxiliary position Q1 to the second auxiliary position Q2, the auxiliary member 50 can contact each other through the first guide portion 86 and the first auxiliary guide feature 88, so that the first locking member 52 moves from the unlocking position J1 (such as Fig.12 As shown) moves toward the height direction U to the locking position J2 (as shown Fig.14 As shown), and the auxiliary member 50 is in the second auxiliary position Q2 to support the first locking member 52, so as to keep the first locking member 52 in the locked position J2 (as shown). Fig.14 On the other hand, when the auxiliary member 50 is in the second auxiliary position Q2, the auxiliary member 50 presses the second locking member 54 to keep the second locking member 54 in the locked position J2' (as shown in FIG. Fig.14 In addition, since the working member 48 is swung from the first working position M1 to the second working position M2, the working portion 76 of the working member 48 can be released from the actuating portion 74 of the second accessory 36 (as shown in FIG. Fig.14 shown).

[0066] Preferably, when the workpiece 48 is moved from the first working position M1 (eg Fig.12 As shown) moves to the second working position M2 (as shown Fig.14 During the process shown in FIG. 1 , the auxiliary member 50 is driven by the working member 48 from the first auxiliary position Q1 (as shown in FIG. 1 ). Fig.12 As shown) moves to the second auxiliary position Q2 (as shown Fig.14 shown).

[0067] It is worth mentioning that when the second accessory 36 of the first interlocking lock assembly 32a is displaced from the extended position E to the other predetermined direction D2 to the retracted position R relative to the first accessory 34, the second accessory 36 can not only bring the auxiliary component 50 from the second auxiliary position Q2 back to the first auxiliary position Q1 through the first predetermined portion 78, but also the second accessory 36 in the second installation position K2 can contact the other working portion 130 of the working piece 48, so that the supporting feature 64 of the working piece 48 is released from the bent portion 62 of the base 46, so that the working piece 48 is deflected and returned to the right position from the second working position M2 to the first working position M1, and the second accessory 36 of the first interlocking lock assembly 32a returns to the retracted position R (such as Fig.12 shown).

[0068] In short, when the second accessory 36 of the first chain lock kit 32a is at any position within the range of the above-mentioned predetermined spacing (for example, the first installation position K1 or the second installation position K2), and the second accessory 36 moves in the predetermined direction D1 relative to the first accessory 34, the auxiliary component 50 is driven to move from the first auxiliary position Q1 to the second auxiliary position Q2, so as to keep the chain lock mechanism 40 in a locked state (for example, the first locking component 52 and the second locking component 54 are both kept in the locked position), so as to provide the function of the chain lock.

[0069] It can be seen that the furniture assembly and the interlocking lock kit provided by the embodiments of the present invention have the following features:

[0070] 1. The user can install a chain lock kit (such as the first chain lock kit 32a) according to the needs to add the chain lock function to the furniture.

[0071] 2. There is a predetermined distance G between the first accessory 34 and the second accessory 36. In response to the possible installation tolerance between them, the interlocking function can be normally operated within the predetermined distance G. Alternatively, the actuating portion 74 of the second accessory 36 and the working portion 76 of the working piece 48 have different extension heights (such as Figure 4 or Figure 6 The first extension height h1 and the second extension height h2 shown in the figure can be used to allow the interlocking function to operate normally when the second accessory 36 is installed in at least two different installation positions (the first installation position K1 or the second installation position K2) relative to the drawer. Further, when the second accessory 36 is in the first installation position K1 or the second installation position K2 relative to the drawer, the auxiliary member 50 can be driven to the second auxiliary position Q2, so that the interlocking mechanism 40 can remain in a locked state.

[0072] Although the present invention has been described with reference to the current specific embodiments, those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and various equivalent changes and modifications may be made without departing from the spirit of the present invention. Therefore, any changes and modifications to the above embodiments within the spirit of the present invention will fall within the scope of the claims of this application.
