The first component 42, on the other hand, is configured to connect with the second furniture part 24a via at least one connecting feature 91 (e.g., threadedly).
The second furniture part 24a can be moved via the second rail 30 to enter an opened or retracted state with respect to the first furniture part 22. Here in FIG. 8, the second furniture part 24a is in the retracted state by way of example. As shown in FIG. 8, a first longitudinal distance L1 exists between a front portion 93 (e.g., a front panel) of the second furniture part 24a and a front edge 95 of the first furniture part 22 before the first adjusting element 46 is operated, and a first transverse distance T1 exists between a lateral portion of the second furniture part 24a and a lateral portion of the first furniture part 22 before the second adjusting element 52 is operated.
Preferably, the first component 42 and the second component 44 have a first scale feature M1 and a first indicator feature K1 respectively, wherein the first scale feature M1 and the first indicator feature K1 are configured to work with each other. The relative positions of the first indicator feature K1 and the first scale feature M1 serve as a visual indicator of the longitudinal (i.e., depth-wise) position to which the second furniture part 24a is adjusted with respect to the first furniture part 22 (or the relative longitudinal positions of the first component 42 and the second component 44 after the adjustment). In FIG. 8, in which the first adjusting element 46 has yet to be adjusted (i.e., the relative longitudinal positions of the first component 42 and the second component 44 have yet to be adjusted), the first indicator feature K1 corresponds to a neutral position of the first scale feature M1.
Preferably, the second component 44 and the third component 50 have a second scale feature M2 and a second indicator feature K2 respectively, wherein the second scale feature M2 and the second indicator feature K2 are configured to work with each other. The relative positions of the second indicator feature K2 and the second scale feature M2 serve as a visual indicator of the transverse (i.e., lateral) position to which the second furniture part 24a is adjusted with respect to the first furniture part 22 (or the relative transverse positions of the second component 44 and the third component 50 after the adjustment). In FIG. 8, in which the second adjusting element 52 has yet to be adjusted (i.e., the relative transverse positions of the second component 44 and the third component 50 have yet to be adjusted), the second indicator feature K2 corresponds to a neutral position of the second scale feature M2.
Referring to FIG. 9 in conjunction with FIG. 8, when the first adjusting element 46 is operated, the first feature 56 and the second feature 58 (e.g., an internal thread and an external thread as shown in FIG. 7) work with each other to effect relative longitudinal displacement, and hence relative adjustment, of the second component 44 and the first component 42.
In this embodiment, in which the third component 50 is hooked (and thus fastened) to the second rail 30, the cooperating first and second transverse guiding features 80, 82 of the second and the third components 44, 50 prevent the second component 44 from being longitudinally displaced with respect to the first component 42; in other words, given the configuration of the embodiment, only the first component 42 can be longitudinally displaced with respect to the second component 44 but not the other way around. More specifically, when the first adjusting element 46 is operated by being rotated in a first direction R1, the first structure 48 responds to this operation of the first adjusting element 46 by displacing the first component 42 longitudinally with respect to the second component 44 in a first adjustment direction D1 (e.g., toward the front); as a result, the second furniture part 24a is displaced with respect to the first furniture part 22 in the first adjustment direction D1 from a first longitudinal position P1 (see FIG. 8) to a second longitudinal position P2 (see FIG. 9), thereby turning the distance between the front portion 93 of the second furniture part 24a and the front edge 95 of the first furniture part 22 from the first longitudinal distance L1 (see FIG. 8) to a second longitudinal distance L2 (see FIG. 9), wherein the second longitudinal distance L2 is greater than the first longitudinal distance L1. Now that the longitudinal position of the first component 42 with respect to the second component 44 is adjusted in the first adjustment direction D1 by operating the first adjusting element 46, the first indicator feature K1 corresponds no more to the neutral position of the first scale feature M1 (see FIG. 8) but to one of the graduation marks of the first scale feature M1 (see FIG. 9), in order for the user to check the adjusted position visually.
Referring to FIG. 10 in conjunction with FIG. 8, when the first adjusting element 46 is operated by being rotated in a second direction R2, the first structure 48 responds to this operation of the first adjusting element 46 by displacing the first component 42 longitudinally with respect to the second component 44 in a second adjustment direction D2 (e.g., toward the rear); as a result, the second furniture part 24a is displaced with respect to the first furniture part 22 in the second adjustment direction D2 from the first longitudinal position P1 (see FIG. 8) to a third longitudinal position P3 (see FIG. 10), thereby turning the distance between the front portion 93 of the second furniture part 24a and the front edge 95 of the first furniture part 22 from the first longitudinal distance L1 (see FIG. 8) to a third longitudinal distance L3 (see FIG. 10), wherein the third longitudinal distance L3 is smaller than the first longitudinal distance L1. Now that the longitudinal position of the first component 42 with respect to the second component 44 is adjusted in the second adjustment direction D2 by operating the first adjusting element 46, the first indicator feature K1 corresponds no more to the neutral position of the first scale feature M1 (see FIG. 8) but to one of the graduation marks of the first scale feature M1 (see FIG. 10), in order for the user to check the adjusted position visually.
It is worth mentioning that the first component 42, whose second space H2 is larger than the body 88b of the second connecting member 88, does not interfere with the second connecting member 88 when longitudinally displaced with respect to the second component 44 in either the first adjustment direction D1 (see FIG. 9) or the second adjustment direction D2 (see FIG. 10), and that the head 76a of the first connecting member 76 does not interfere with the third component 50, whose first space H1 is larger than the head 76a of the first connecting member 76, when the first component 42 is longitudinally displaced with respect to the second component 44 in either the first adjustment direction D1 (see FIG. 9) or the second adjustment direction D2 (see FIG. 10).
Referring to FIG. 11 in conjunction with FIG. 8, when the second adjusting element 52 is operated, the adjusting portion 53 and the second structure 54 work with each other to effect relative transverse displacement, and hence relative adjustment, of the second component 44 and the third component 50.
In this embodiment, in which the third component 50 is hooked (and thus fastened) to the second rail 30, only the second component 44 can be transversely displaced with respect to the third component 50 but not the other way around. The cooperating second and first longitudinal guiding features 72, 70 of the second and the first components 44, 42 cause the second and the first components 44, 22 to be transversely displaced with respect to the third component 50 in unison. More specifically, when the second adjusting element 52 is operated by being rotated in a third direction R3, the second structure 54 is pressed against one of the two sidewalls of the adjusting portion 53 (e.g., a guide groove or a guide channel) and thereby generates a pushing force that displaces the second component 44 and the first component 42 transversely with respect to the third component 50 in a third adjustment direction D3 (e.g., toward the right); as a result, the second furniture part 24a is displaced with respect to the first furniture part 22 in the third adjustment direction D3 from a first transverse position S1 (see FIG. 8) to a second transverse position S2 (see FIG. 11), thus turning the distance between the aforesaid lateral portion of the second furniture part 24a and the aforesaid lateral portion of the first furniture part 22 from the first transverse distance T1 (see FIG. 8) to a second transverse distance T2 (see FIG. 11), wherein the second transverse distance T2 is smaller than the first transverse distance T1. Now that the transverse position of the second component 44 with respect to the third component 50 is adjusted in the third adjustment direction D3 (e.g., toward the right) by operating the second adjusting element 52, the second indicator feature K2 corresponds no more to the neutral position of the second scale feature M2 (see FIG. 8) but to one of the graduation marks of the second scale feature M2 (see FIG. 11), in order for the user to check the adjusted position visually.
Referring to FIG. 12 in conjunction with FIG. 8, when the second adjusting element 52 is operated by being rotated in a fourth direction R4, the second structure 54 is pressed against one of the two sidewalls of the adjusting portion 53 (e.g., a guide groove or a guide channel) and thereby generates a pushing force that displaces the second component 44 and the first component 42 transversely with respect to the third component 50 in a fourth adjustment direction D4 (e.g., toward the left); as a result, the second furniture part 24a is displaced with respect to the first furniture part 22 in the fourth adjustment direction D4 from the first transverse position S1 (see FIG. 8) to a third transverse position S3 (see FIG. 12), thus turning the distance between the aforesaid lateral portion of the second furniture part 24a and the aforesaid lateral portion of the first furniture part 22 from the first transverse distance T1 (see FIG. 8) to a third transverse distance T3 (see FIG. 12), wherein the third transverse distance T3 is greater than the first transverse distance T1. Now that the transverse position of the second component 44 with respect to the third component 50 is adjusted in the fourth adjustment direction D4 (e.g., toward the left) by operating the second adjusting element 52, the second indicator feature K2 corresponds no more to the neutral position of the second scale feature M2 (see FIG. 8) but to one of the graduation marks of the second scale feature M2 (see FIG. 12), in order for the user to check the adjusted position visually.
It can be known from the above that the adjustment mechanism in the foregoing embodiment preferably has the following features:
1. When the first adjusting element 46 is operated (e.g., rotated), the second component 44 and the first component 42 are longitudinally displaced (i.e., adjusted) with respect to each other through cooperation between the first feature 56 and the second feature 58.
2. Longitudinal (i.e., depth-wise) and transverse (i.e., lateral) adjustment can be achieved by relative longitudinal displacement of the first component 42 and the second component 44, relative transverse displacement of the second component 44 and the third component 50, and cooperation between the two adjusting elements 46, 52 and the two structures 48, 54.
3. The adjustment mechanism 34 can displace (i.e., adjust) an object (e.g., the second furniture part 24a) with respect to the first furniture part 22 in four directions (i.e., the first to the fourth adjustment directions D1 to D4, e.g., toward the front, rear, right, and left) in order to deal with or compensate for mounting errors that may exist between the object (e.g., the second furniture part 24a) and the first furniture part 22 (or a slide rail).
4. The adjustment mechanism 34 is mounted on (e.g., detachably connected to) a slide rail (e.g., the second rail 30) and/or an object (e.g., the second furniture part 24a).
5. The axis of the first adjusting element 46 is substantially perpendicular to that of the second adjusting element 52; in other words, the first structure 48 is disposed in a direction that is perpendicular to the direction in which the shaft portion 78 is disposed.
6. The cooperating first scale feature M1 and first indicator feature K1 of the first and the second components 42, 44 enable the user to visually check the longitudinal (i.e., depth-wise) position to which the second furniture part 24a is adjusted with respect to the first furniture part 22 (or the relative longitudinal positions of the first component 42 and the second component 44) Similarly, the cooperating second scale feature M2 and second indicator feature K2 of the second and the third components 44, 50 enable the user to visually check the transverse (i.e., lateral) position to which the second furniture part 24a is adjusted with respect to the first furniture part 22 (or the relative transverse positions of the second component 44 and the third component 50).
