The second rail can be displaced relative to the first rail; the third rail can be displaced relative to the second rail; the synchronization device is arranged on one of the second rail and the third rail; the contact feature is arranged on the other of the second rail and the third rail; the third rail and the second rail can synchronously displace relative to the first rail through the matching action of the synchronous device and the contact characteristic.
Description
Technical Field
The present invention relates to a sliding rail assembly, and more particularly to a sliding rail assembly with synchronous displacement function for two sliding rails.
Background
For example, U.S. patent publication No. US 5,181,782A discloses a telescopic rail assembly comprising an outer rail, a middle rail and an inner rail (drawer rail). The middle rail is provided with a stop block, and the inner rail is provided with a protrusion. As shown in fig. 3 to 5 of the patent, when the inner rail is pulled out in the opening direction, the inner rail can contact the protrusion of the flexible finger of the stopper through the protrusion and accordingly the middle rail can be pulled out in the opening direction following the inner rail.
As can be seen from fig. 1 or 7 of the patent, since the ends of the two flexible fingers of the stopper are not connected to each other, an opening is formed between the two flexible fingers to be in an open design. Therefore, in the case that the ends of the two flexible fingers of the stopper are not connected to each other, once the sliding rails are opened or closed with respect to each other for a long period of time, the two flexible fingers are easily warped, turned outwards or broken, so that the protrusion of the inner rail may not cooperate with the two flexible fingers, so that the middle rail cannot be pulled out in the opening direction in synchronization with the inner rail.
Therefore, how to develop a different slide rail product becomes an important issue according to different market demands.

The second rail 24 has a first end f2 and a second end r2, such as a front end and a rear end, but is not limited thereto. Preferably, the sliding rail assembly 20 further comprises a first sliding assisting device 36 movably mounted between the first rail 22 and the second rail 24, wherein the first sliding assisting device 36 comprises an upper bead 38a and a lower bead 38b respectively arranged in the first channel of the first rail 22 and adjacent to the first wall 28a and the second wall 28b of the first rail 22.

The second sliding assisting device 45 includes a plurality of rolling elements 43, and the rolling elements 43 are balls or rollers, for example, to assist the smoothness of the displacement of the second rail 24 and the third rail 26 relative to each other. Preferably, the second stop 34 of the first rail 22 includes a guiding feature 64, and the guiding feature 64 is exemplified by, but not limited to, a slope or a curved surface.
The slide assembly 20 also includes a synchronization device 50 and a contact feature 52. The synchronization device 50 is disposed on one of the second rail 24 and the third rail 26, and the contact feature 52 (shown in fig. 3) is disposed on the other of the second rail 24 and the third rail 26. Here, the synchronization device 50 is disposed on the second rail 24, and the contact feature 52 is disposed on the third rail 26, for example, but not limited to, implementation. The synchronization device 50 and the second rail 24 may form a sliding rail set.
The synchronization device 50 can be integrated directly into the second rail 24; or, in the present embodiment, the synchronization device 50 is removably mounted to the second rail 24. Further, the longitudinal wall 44 of the second rail 24 has a first mounting portion M1, and the synchronization device 50 is mounted to the first mounting portion M1 by a second mounting portion M2. The first mounting portion M1 and the second mounting portion M2 may be configured with a convex structure and a concave structure (holes), but the implementation is not limited thereto. Preferably, the synchronization device 50 is a separate piece and is made of a flexible material, such as plastic, but is not limited in implementation. Preferably, the synchronization device 50 includes a first portion 54, a second portion 56 and a body portion 58 connected between the first portion 54 and the second portion 56 (as shown in fig. 3), wherein the body portion 58 includes a first body 58a and a second body 58b connected to the first body 58a. Wherein the first portion 54 and the second portion 56 have substantially the same structural configuration, but are not limited in implementation. Preferably, the first portion 54 of the synchronization device 50 is relatively close to the first wall 42a of the second rail 24 relative to the second portion 56; the second portion 56 of the synchronization device 50 is relatively close to the second wall 42b of the second rail 24 relative to the first portion 54. Preferably, a first opening H1 is provided between the first portion 54 and the body portion 58. Similarly, a second opening H2 is provided between the second portion 56 and the body portion 58. The first portion 54 of the synchronization device 50 is arranged with a first corresponding section 54a, a second corresponding section 54b and an extension section 54c connected between the first corresponding section 54a and the second corresponding section 54 b. Wherein the first corresponding section 54a is connected between the extension section 54c and (the first main body 58a of) the body portion 58; the second corresponding section 54b is connected between the extension section 54c and (the second main body 58b of) the body portion 58.
The contact feature 52 (shown in fig. 3) includes a first contact section 60 and a second contact section 62, and preferably also includes an intermediate section 61 connected between the first contact section 60 and the second contact section 62. Here, the contact features 52 are arranged on both the first wall 46a and the second wall 46b of the third rail 26, and the two contact features 52 have substantially the same structural configuration. The two contact features 52 are configured to mate with the first portion 54 and the second portion 56 of the synchronization device 50, respectively, and the principle of the mating is substantially the same. The two contact features 52 are each exemplified by a protrusion, but are not limited in implementation.
As shown in fig. 3, the sliding rail assembly 20 is in a retracted state. The second rail 24 is folded with respect to the first rail 22, and the third rail 26 is at a folding position R with respect to the second rail 24. When the third rail 26 is at the retracted position R relative to the second rail 24, the third rail 26 can be blocked by the guiding feature 64 of the second blocking portion 34 of the first rail 22 in a first direction D1 by the contact feature 52, so as to prevent the third rail 26 from moving away from the retracted position R in the first direction D1. In other words, the slide rail assembly 20 can be maintained in the retracted state. It should be noted that one of the first contact section 60 of the contact feature 52 and the first corresponding section 54a of the synchronization device 50 includes a slant surface or a cambered surface, and both of them are exemplified as slant surfaces or cambered surfaces, but the implementation is not limited thereto.
Further, when the third rail 26 receives a force from the retracted position R to displace longitudinally a distance in the first direction D1 relative to the first rail 22, if the force is large enough to overcome the flexible deformability of the second stopper 34, the (first contact section 60 of the) contact feature 52 of the third rail 26 can contact the guide feature 64 of the second stopper 34, and the contact feature 52 can be guided by the guide feature 64 to pass over the second stopper 34 in the first direction D1
As shown in fig. 4, when the third rail 26 is moved in the first direction D1 relative to the first rail 22 by an external force, the third rail 26 and the second rail 24 can be moved synchronously in the first direction D1 relative to the first rail 22 by the mutual matching of the synchronization device 50 and the contact feature 52. Further, the contact feature 52 enables the third rail 26 and the second rail 24 to be displaced synchronously in the first direction D1 by the mutual abutment of the first contact section 60 and the first corresponding section 54a of the synchronization device 50. At this time, the upper bead 38a and the lower bead 38b of the first sliding-assisting device 36 are also displaced in the first direction D1. Preferably, the first wall 42a and the second wall 42b of the second rail 24 are respectively provided with a first pushing portion 47a and a second pushing portion 47b.
As shown in fig. 5, when the second rail 24 moves to an extended position P1 in synchronization with the third rail 26 in the first direction D1, the second rail 24 is blocked by the first blocking portion 32 of the first rail 22, so that the second rail 24 stays at the extended position P1 relative to the first rail 22. Here, taking the front ends of the upper bead 38a and the lower bead 38b of the first sliding-assisting device 36 respectively abutting against the two first blocking portions 32 of the first rail 22, and the first pushing portion 47a and the second pushing portion 47b of the second rail 24 respectively abutting against the rear ends of the upper bead 38a and the lower bead 38b of the first sliding-assisting device 36, the second rail 24 can be kept at the extended position P1 relative to the first rail 22 according to this configuration. In other alternative embodiments, if the slide rail assembly 20 does not have the upper bead 38a and the lower bead 38b, the second rail 24 can be directly blocked by the two first blocking portions 32 of the first rail 22 by the first pushing portion 47a and the second pushing portion 47b, and the second rail 24 can also be kept in a more unfolded and extended position relative to the first rail 22, which is thus not limited in implementation.
As shown in fig. 5 and 6, the first contact section 60 of the contact feature 52 and the first corresponding section 54a of the synchronization device 50 of the present embodiment both include an inclined surface or an arc surface. When the external force is further increased, since the second rail 24 is blocked by the first rail 22, when the third rail 26 is further displaced toward the first direction D1 relative to the second rail 24 at the extended position P1, the first contact section 60 of the contact feature 52 can push against the first corresponding section 54a of the synchronization device 50 through the inclined surface or the cambered surface, so that the synchronization device 50 is flexibly deformed (as shown in fig. 6), and the first contact section 60 of the contact feature 52 passes over the first corresponding section 54a of the synchronization device 50. Wherein, as shown in fig. 6, the first portion 54 and the second portion 56 of the synchronization device 50 can be pushed (or pressed) by the middle section 61 of the contact feature 52 of the first wall 46a and the second wall 46b of the third rail 26, respectively. Preferably, the first opening H1 facilitates the first portion 54 of the synchronization device 50 to flexibly deform toward the main body 58 in a first predetermined direction B1; similarly, the second portion 56 of the synchronization device 50 is facilitated to flexibly deform toward the body portion 58 in a second predetermined direction B2 opposite to the first predetermined direction B1 through the second opening H2.
As shown in fig. 7, the slide assembly 20 is in an extended state. Specifically, after the contact feature 52 passes over the first corresponding section 54a of the synchronization device 50 in the first direction D1, the third rail 26 can be displaced to an open position P2 relative to the second rail 24 in the extended position P1.
As shown in fig. 8, one of the second contact section 62 of the contact feature 52 and the second corresponding section 54b of the synchronization device 50 includes a bevel or a cambered surface, which are both, for example, but not limited to, a bevel or a cambered surface. Further, during the displacement of the third rail 26 from the open position P2 to a second direction D2 opposite to the first direction D1, the third rail 26 and the second rail 24 can be synchronously displaced relative to the first rail 22 to the second direction D2 by the mutual matching of the synchronizing device 50 and the contact feature 52. Wherein, during the displacement of the third rail 26 from the above-mentioned open position P2 toward the second direction D2, the contact feature 52 enables the third rail 26 and the second rail 24 to be synchronously displaced toward the second direction D2 relative to the first rail 22 by the mutual abutment of the second contact segment 62 and the second corresponding segment 54b of the synchronization device 50.
As shown in fig. 9, when the second rail 24 moves to a predetermined folding position X in synchronization with the third rail 26 in the second direction D2, a portion of the second rail 24 (e.g., the second end r2 of the second rail 24) is blocked by the second blocking portion 34 of the first rail 22 and stays at the predetermined folding position X.
As shown in fig. 9 and 10, the second contact section 62 of the contact feature 52 and the second corresponding section 54b of the synchronization device 50 of the present embodiment both include an inclined surface or an arc surface. When the third rail 26 is further displaced in the second direction D2 relative to the second rail 24 at the predetermined retracted position X, the second contact section 62 of the contact feature 52 can push against the second corresponding section 54b of the synchronization device 50 through the inclined surface or the cambered surface, so as to flexibly deform the synchronization device 50 (the principle of the flexible deformation is substantially the same as that of the synchronization device 50 shown in fig. 6), and the second contact section 62 of the contact feature 52 passes over the second corresponding section 54b of the synchronization device 50. Wherein, as shown in fig. 10, the first portion 54 and the second portion 56 of the synchronization device 50 can be pushed (or pressed) by the middle section 61 of the contact feature 52 of the first wall 46a and the second wall 46b of the third rail 26, respectively. Preferably, the first opening H1 facilitates the first portion 54 of the synchronization device 50 to flexibly deform toward the main body 58 in the first predetermined direction B1; similarly, the second portion 56 of the synchronization device 50 is facilitated to flexibly deform toward the body portion 58 in the second predetermined direction B2. After the contact feature 52 passes over the second corresponding section 54b of the synchronization device 50 in the second direction D2, the third rail 26 can be displaced relative to the second rail 24 at the predetermined retracted position X to return to the retracted position R (this portion can also be combined with fig. 3).
From the above description, it can be seen that the enhancement effect and advantage of the present invention are:
1. By the cooperation of the synchronizing device 50 and the contact feature 52, the third rail 26 and the second rail 24 can be synchronously displaced in the first direction D1 or the second direction D2 relative to the first rail 22.
2. By the cooperation of the synchronizing device 50 and the contact feature 52, the third rail 26 and the second rail 24 can have a synchronous displacement function. Overall, the structure is simplified.
3. The first portion 54 of the synchronization device 50 is arranged with the first corresponding section 54a, the second corresponding section 54b and the extension section 54c connected between the first corresponding section 54a and the second corresponding section 54 b. Wherein the first corresponding segment 54a is connected between the extension segment 54c and (the first main body 58a of) the body portion 58, and the second corresponding segment 54b is connected between the extension segment 54c and (the second main body 58b of) the body portion 58. According to this configuration, the synchronization device 50 has better structural strength than the prior art, and can improve the service efficiency of the synchronization device 50, so that the synchronization displacement function of the sliding rail assembly 20 is more reliable.
4. The synchronization device 50 is made of a flexible material. Wherein, through the first opening H1, the first portion 54 of the synchronization device 50 is facilitated to flexibly deform toward the body portion 58; similarly, the second portion 56 of the synchronization device 50 is facilitated to flexibly deform toward the body portion 58 by the second opening H2.
5. The synchronization device 50 is detachably mounted to a sliding rail (e.g., the second rail 24), so that the synchronization device 50 can be mounted to the sliding rail according to the needs of the user.
While the application has been described with reference to the present specific embodiments, it will be appreciated by those skilled in the art that the above embodiments are for illustration only and that various equivalent changes and modifications may be made without departing from the spirit of the application, and therefore, all changes and modifications to the above embodiments shall fall within the scope of the appended claims.
