Description
Technical Field
The present invention relates to a slide rail assembly, and more particularly to a slide rail assembly with two slide rails having a synchronous displacement function.
Background
For example, U.S. patent publication No. US 5,181,782a discloses a retractable slide rail assembly including 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 projection. 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 along with 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 form 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 relative to each other for a long time, the two flexible fingers are easily warped, turned outwards or broken, so that the protrusion of the inner rail may not be able to cooperate with the two flexible fingers, and the middle rail may not be able to be pulled out in the opening direction synchronously with the inner rail.
Therefore, with different market demands, how to develop a different slide rail product becomes an important issue.

On the other hand, a second stopper 34 is arranged adjacent to the second end r1 of the first rail 22, where the second stopper 34 is an additional fitting made of flexible material, for example, mounted adjacent to the second end r1 of the first rail 22. For example, the longitudinal wall 30 of the first rail 22 has a first connection portion K1, and the fitting is connectable to the first connection portion K1 through a second connection portion K2. The first connecting portion K1 and the second connecting portion K2 may be configured as a protrusion and a recess (hole), but are not limited in implementation. In other alternative embodiments, the second stopper 34 can be directly formed adjacent to the second end r1 of the first rail 22, and therefore, is not limited in implementation.
The second rail 24 includes a first wall 42a, a second wall 42b and a longitudinal wall 44 connected between the first wall 42a and the second wall 42b of the second rail 24.

The second rail 24 has a first end f2 and a second end r2, such as a front end and a rear end, but not limited to the embodiment. Preferably, the slide rail assembly 20 further comprises a first sliding aid 36 movably mounted between the first rail 22 and the second rail 24, wherein the first sliding aid 36 comprises an upper bead 38a and a lower bead 38b respectively disposed 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 third rail 26 includes a first wall 46a, a second wall 46b and a longitudinal wall 48 connected between the first wall 46a and the second wall 46b of the third rail 26. The first wall 46a, the second wall 46b and the longitudinal wall 48 of the third rail 26 are positioned to correspond to the first wall 42a, the second wall 42b and the longitudinal wall 44 of the second rail 24, respectively.

Preferably, the slide rail assembly 20 further comprises a second sliding aid 45 movably mounted between the second rail 24 and the third rail 26. The second sliding assisting device 45 comprises a plurality of rolling members 43, and the rolling members 43 are, for example, balls or rollers, for assisting the smoothness of the displacement of the second rail 24 and the third rail 26 relative to each other. Preferably, the second stop portion 34 of the first rail 22 includes a guiding feature 64, and the guiding feature 64 is an inclined surface or an arc surface, for example, but not limited to implementation.
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. Wherein, the synchronization device 50 and the second rail 24 can form a sliding rail kit.
The synchronization device 50 may be integrated directly into the second rail 24; alternatively, the synchronization device 50 may be removably mounted to the second rail 24, as in the present embodiment. Further, the longitudinal wall 44 of the second rail 24 has a first mounting portion M1, and the synchronization device 50 is mountable to the first mounting portion M1 through a second mounting portion M2. The first mounting portion M1 and the second mounting portion M2 may be configured as a protrusion and a recess (hole), but are not limited thereto. Preferably, the synchronization device 50 is a separate piece made of a flexible material, such as plastic, but 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), where the body portion 58 includes a first body 58a and a second body 58b connected to the first body 58 a. 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 closer to the first wall 42a of the second rail 24 than the second portion 56; the second portion 56 of the synchronization device 50 is closer to the second wall 42b of the second rail 24 than the first portion 54. Preferably, a first opening H1 is formed between the first portion 54 and the body portion 58. Similarly, the second portion 56 and the body portion 58 have a second opening H2 therebetween. 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 main body portion 58; the second corresponding section 54b is connected between the extension section 54c and (the second 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 further includes an intermediate section 61 connected between the first contact section 60 and the second contact section 62. Here, the first wall 46a and the second wall 46b of the third rail 26 are both arranged with contact features 52, and the two contact features 52 have substantially the same structural configuration. The two contact features 52 are configured to cooperate with the first portion 54 and the second portion 56 of the synchronization device 50, respectively, and the principles of the cooperation are substantially the same. The two contact features 52 are illustrated as a protrusion, but are not limited in implementation.
As shown in fig. 3, the slide assembly 20 is in a retracted state. The second rail 24 is folded relative to the first rail 22, and the third rail 26 is located at a folded position R relative to the second rail 24. When the third rail 26 is in the retracted position R relative to the second rail 24, the third rail 26 can be stopped by the guiding feature 64 of the second stopper 34 of the first rail 22 in a first direction D1 through the contact feature 52 to prevent the third rail 26 from moving away from the retracted position R arbitrarily in the first direction D1. In other words, the slide assembly 20 can be maintained in the retracted state. It should be noted that one of the first contacting portion 60 of the contacting feature 52 and the first corresponding portion 54a of the synchronization device 50 includes a slant surface or a curved surface, and both are exemplified as slant surfaces or curved surfaces, but the implementation is not limited thereto.
Further, when the third rail 26 receives a force from the retracted position R and longitudinally displaces a distance relative to the first rail 22 in the first direction D1, if the force is large enough to overcome the flexible deformation capability of the second stopper 34, the (first contact section 60 of the) contact feature 52 of the third rail 26 can contact the guiding feature 64 of the second stopper 34, and the contact feature 52 can be guided by the guiding 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 continuously displaced toward the first direction D1 relative to the first rail 22 by an external force, the synchronization device 50 and the contact feature 52 are matched with each other, so that the third rail 26 and the second rail 24 can be synchronously displaced toward the first direction D1 relative to the first rail 22. Further, the contact feature 52 enables the third rail 26 and the second rail 24 to be synchronously displaced toward the first direction D1 by the abutting 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 aid 36 are also displaced along 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 47 b.
As shown in fig. 5, when the second rail 24 is synchronously displaced to an extended position P1 along the first direction D1 along with the third rail 26, 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. Herein, taking the front ends of the upper bead 38a and the lower bead 38b of the first sliding assistance device 36 respectively abut 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 abut against the rear ends of the upper bead 38a and the lower bead 38b of the first sliding assistance device 36, according to this configuration, the second rail 24 can stay at the extended position P1 relative to the first rail 22. 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 through the first pushing portion 47a and the second pushing portion 47b, and the second rail 24 can also stay at a more extended position relative to the first rail 22, and therefore, the implementation is not limited.
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 a slope or a curved surface. When the external force is further increased, since the second rail 24 is stopped by the first rail 22, when the third rail 26 is continuously 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 curved 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) against 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, by means of the first opening H1, the first portion 54 of the synchronization device 50 is facilitated to be flexibly deformed towards the body portion 58 in a first predetermined direction B1; similarly, the second opening H2 facilitates flexible deformation of the second portion 56 of the synchronization device 50 toward the body portion 58 in a second predetermined direction B2 opposite the first predetermined direction B1.
As shown in fig. 7, the slide rail assembly 20 is in an extended state. Specifically, after the contact feature 52 passes over the first corresponding segment 54a of the synchronization device 50 in the first direction D1, the third rail 26 may 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 segment 62 of the contact feature 52 and the second corresponding segment 54b of the synchronization device 50 includes a slant surface or a curved surface, and both are exemplified as slant surfaces or curved surfaces, but not limited thereto. Further, when the third rail 26 is displaced from the open position P2 to a second direction D2 opposite to the first direction D1, the synchronization device 50 and the contact feature 52 are matched with each other, so that the third rail 26 and the second rail 24 can be synchronously displaced relative to the first rail 22 to the second direction D2. When the third rail 26 is displaced from the open position P2 to the second direction D2, the contact feature 52 enables the third rail 26 and the second rail 24 to be synchronously displaced to the second direction D2 relative to the first rail 22 by the abutting 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 is synchronously moved to a predetermined retracted position X along 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 retracted 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 a bevel or a curved surface. When the third rail 26 is further displaced toward 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 curved surface, so that the synchronization device 50 is flexibly deformed (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) against 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, by means of the first opening H1, the first portion 54 of the synchronization device 50 is facilitated to be flexibly deformed towards the body portion 58 in the first predetermined direction B1; similarly, the second opening H2 facilitates flexible deformation of the second portion 56 of the synchronization device 50 toward the body portion 58 in the second predetermined direction B2. After the contact feature 52 passes the second corresponding segment 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 (see fig. 3).
From the above description, it can be seen that the enhanced efficacy and advantages of the present invention are:
1. by the mutual cooperation of the synchronization device 50 and the contact feature 52, the third rail 26 and the second rail 24 can be synchronously displaced relative to the first rail 22 in the first direction D1 or the second direction D2.
2. The synchronization device 50 and the contact feature 52 are matched to each other, so that the third rail 26 and the second rail 24 have a synchronization displacement function. Overall, have the structure and refine the simplification.
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 section 54a is connected between the extension section 54c and (the first main body 58a of) the main body 58, and the second corresponding section 54b is connected between the extension section 54c and (the second main body 58b of) the main body 58. According to this configuration, the synchronization device 50 has better structural strength than the prior art, so as to improve the utilization efficiency of the synchronization device 50 and make the synchronization displacement function of the slide rail assembly 20 better and more reliable.
4. The synchronization device 50 is made of a flexible material. Wherein, via the first opening H1, the first portion 54 of the synchronization device 50 is facilitated to be flexibly deformed toward the body portion 58; similarly, the second portion 56 of the synchronization device 50 is facilitated to be flexibly deformed toward the body portion 58 through the second opening H2.
5. The synchronization device 50 is detachably mounted to a slide rail (e.g., the second rail 24), so that the synchronization device 50 can be mounted to the slide rail according to the user's needs.
Although the present invention has been described with reference to the present specific embodiments, it will be recognized by those skilled in the art that the above embodiments are illustrative only, and various equivalent changes and modifications may be made without departing from the spirit of the present invention, and therefore, it is intended to cover in the appended claims all such changes and modifications as fall within the true spirit of the invention.
