Abstract

A slide rail assembly includes a first rail, a second rail, a synchronous member, an auxiliary member and a third rail. The synchronous member is movably mounted on the second rail. The third rail is arranged with a working feature. During a process that the third rail is displaced in an opening direction, the third rail is synchronously moved with the second rail through the working feature and the synchronous member contacting with one another. During a process that the third rail and the second rail are synchronously displaced in the opening direction, a blocking feature on the first rail is configured to contact with the auxiliary member such that the auxiliary member is moved relative to the second rail for driving the synchronous member not to be contacted with the working feature of the third rail to terminate the synchronous relationship between the third rail and the second rail.

Description

Slide rail assembly

The present invention relates to a slide rail, and more particularly to a slide rail assembly that can release the synchronous displacement relationship between two slide rails through an auxiliary component.

For example, US Patent Publication No. US 7,357,468 B2 discloses a sliding rail assembly including an outer rail, a middle rail and an inner rail. The middle rail is movably installed between the outer rail and the inner rail, and the outer rail, the middle rail and the inner rail can be longitudinally displaced relative to each other. A linking member, a positioning member and an elastic member are arranged on the middle rail. The linking member and the positioning member are pivotally connected to the middle rail. The inner rail is provided with a first protrusion; the first protrusion is provided with a locking portion and an inclined surface; the outer rail is provided with a second protrusion, and the second protrusion is provided with a stopping portion and an inclined surface; the connecting member includes a locking end and a releasing end; the positioning member includes a releasing end and a fixed end; the elastic member provides elastic force to resist the releasing end of the connecting member and the fixed end of the positioning member; the locking end of the connecting member corresponds to the locking portion of the first protrusion of the inner rail, and the releasing end corresponds to the inclined surface of the second protrusion, the fixed end of the positioning member corresponds to the stopping portion of the second protrusion of the outer rail, and the releasing end corresponds to the inclined surface of the first protrusion. When the slide rail is fully retracted, the linking member abuts against the locking portion of the first convex wall of the inner rail with its abutting end, and the unlocking end of the positioning member is lifted up by the first convex wall. When the inner rail is pulled out, the middle rail is simultaneously pulled out by the locking portion of the first convex wall and the abutting end of the linking member. After being stretched to a fixed point, the unlocking end of the linking member is lifted up by the second convex wall and its inclined surface, so that the abutting end of the linking member is separated from the locking portion of the first convex wall, that is, the relative abutment with the inner rail is released (that is, the synchronous displacement relationship between the middle rail and the inner rail is released). Subsequently, the middle rail can be pulled out again. The inner rail, the first protrusion leaves the release end of the positioning member, so that the fixed end of the positioning member is pressed by the second elastic foot of the elastic element and hooked on the stop portion of the second protrusion. After that, the inner rail is stretched continuously, and the middle rail can be positioned relative to the outer rail by the fixed end of the positioning member against the stop portion of the second protrusion, and the inner rail can continue to be pulled out to the fully stretched position.

It can be seen that the patent case can release the synchronous displacement relationship between the middle rail and the inner rail by lifting the release end of the linkage of the middle rail by the inclined surface of the second convex wall of the outer rail, so that the locking end of the linkage is separated from the locking part of the first convex wall of the inner rail. However, if there is an unexpected installation tolerance between the middle rail and the outer rail, the method disclosed in the patent case to release the synchronous displacement relationship between the middle rail and the inner rail in this way may be affected. Therefore, with the different market demands, how to develop a different sliding rail product has become an issue that cannot be ignored.

One object of the present invention is to provide a slide rail assembly that can release the synchronous displacement relationship between two slide rails through an auxiliary member.

According to one aspect of the present invention, a slide rail assembly includes a first rail, a second rail, a synchronous member, a latch member, an auxiliary member and a third rail. The first rail is provided with a predetermined feature and a blocking feature; the second rail can be displaced longitudinally relative to the first rail; the synchronizing member and the latching member are movably mounted on the second rail; the auxiliary member is movably mounted on the second rail; the third rail can be displaced longitudinally relative to the second rail, and the third rail is provided with a working feature; wherein, when the third rail is displaced in an opening direction, the working feature and the synchronizing member in a first state are in mutual contact, so that the third rail can synchronously drive the second rail to displace; wherein, when the third rail and the second rail are synchronously displaced in the opening direction During the displacement process, the blocking feature and the auxiliary part will contact each other to generate a force, so that the auxiliary part moves from a first auxiliary position to a second auxiliary position relative to the second rail, so as to drive the synchronizer to move from the first state to a second state, so that the synchronizer no longer contacts the working feature of the third rail, thereby releasing the synchronous displacement relationship between the third rail and the second rail; wherein, when the second rail is in an extended position relative to the first rail, the latch is latched to the predetermined feature through the latch to prevent the second rail from being displaced from the extended position to a retracted direction.

According to another aspect of the present invention, a slide rail assembly includes a first rail, a second rail, a synchronous member, an auxiliary member, and a third rail. The first rail is provided with a blocking feature; the second rail can be longitudinally displaced relative to the first rail; the synchronous member is movably mounted on the second rail; the auxiliary member can be in one of a first auxiliary position and a second auxiliary position relative to the second rail; the third rail can be longitudinally displaced relative to the second rail, and the third rail is provided with a working feature; wherein, when the third rail is displaced in an opening direction, the working feature and the synchronous member come into contact with each other, so that The third rail can synchronously drive the second rail to move; wherein, when the third rail and the second rail are synchronously displaced in the opening direction, the blocking feature and the auxiliary part will contact each other, so that the auxiliary part moves linearly from the first auxiliary position to the second auxiliary position relative to the second rail, so as to drive the synchronous part to move, so that the synchronous part no longer contacts the working feature of the third rail, thereby releasing the synchronous displacement relationship between the third rail and the second rail.

In general, the auxiliary part on the second rail drives the synchronous part on the second rail to move, so as to release the synchronous displacement relationship between the third rail and the second rail, so as to meet the diversified needs of the market.

As shown in FIG. 1 and FIG. 2 , a slide rail assembly 20 of an embodiment of the present invention includes a first rail 22, a second rail 24, and a third rail 26 that can be longitudinally displaced relative to each other. Here, 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 side direction of the slide rail), and the Z-axis direction is the vertical direction (or the height direction of the slide rail). Preferably, the second rail 24 (such as the middle rail) is movably installed between the first rail 22 (such as the outer rail) and the third rail 26 (such as the inner rail).

The first rail 22 is provided with a predetermined feature 28 and a blocking feature 30. Further, the first rail 22 includes a first wall 32a, a second wall 32b and a longitudinal wall 34 connected between the first wall 32a and the second wall 32b of the first rail 22. The first wall 32a, the second wall 32b and the longitudinal wall 34 of the first rail 22 jointly define a first channel 36 for accommodating the second rail 24. Preferably, the predetermined feature 28 and the blocking feature 30 are arranged on the longitudinal wall 34 of the first rail 22. Here, the first rail 22 is provided with a predetermined component 38 connected to the longitudinal wall 34 of the first rail 22, and the predetermined component 38 includes the predetermined feature 28. Preferably, the blocking feature 30 is a protrusion. Here, the blocking feature 30 is taken as an example of a vertical wall, but the implementation is not limited.

The second rail 24 includes a first wall 40a, a second wall 40b and a longitudinal wall 42 connected between the first wall 40a and the second wall 40b of the second rail 24. The first wall 40a, the second wall 40b and the longitudinal wall 42 of the second rail 24 jointly define a second channel 44 for accommodating the third rail 26.

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 third rail 26 is arranged with a working feature 45 located on the longitudinal wall 48 of the third rail 26. The working feature 45 is, for example, a hole or a groove, and the hole or groove is defined by a plurality of inner walls, but is not limited in implementation.

Preferably, a first sliding aid device 47 is arranged between the first rail 22 and the second rail 24, and the first sliding aid device 47, for example, includes a plurality of balls, which helps to improve the smoothness of the displacement of the second rail 24 relative to the first rail 22; and a second sliding aid device 49 is arranged between the second rail 24 and the third rail 26, and the second sliding aid device 49, for example, includes a plurality of balls, which helps to improve the smoothness of the displacement of the third rail 26 relative to the second rail 24.

As shown in FIGS. 3 to 5 , the slide rail assembly 20 includes a synchronizing member 50 , a latching member 52 and an auxiliary member 54 arranged on the second rail 24 , and preferably, further includes an elastic structure 56 .

The second rail 24 has a first end 24a and a second end 24b, such as a front end and a rear end, and the second rail 24 has a first side L1 and a second side L2 that are positioned opposite to each other, such as an outer side and an inner side, wherein the first side L1 is adjacent to or faces the first rail 22, and the second side L2 is adjacent to or faces the third rail 26.

Preferably, the longitudinal wall 42 of the second rail 24 is further arranged with at least one through hole, such as a first through hole H1 and a second through hole H2 connecting the first side L1 and the second side L2 of the second rail 24.

Preferably, the synchronizer 50, the latch 52 and the auxiliary member 54 are movably mounted on the second rail 24. The synchronizer 50 and the latch 52 are at different heights. The synchronizer 50 and the latch 52 are pivoted on the second rail 24 via a shaft 58, and the synchronizer 50 and the latch 52 are respectively accommodated in the first through hole H1 and the second through hole H2. The configuration direction of the shaft 58 is substantially the same as a height direction (Z-axis direction) of the second rail 24.

Preferably, the synchronizer 50, the latch 52 and the auxiliary member 54 are adjacent to the second end 24b of the second rail 24.

The synchronizer 50 includes a first portion 50a, a second portion 50b, and a middle portion 50c located between the first portion 50a and the second portion 50b. On the other hand, the latch 52 includes a first section 52a, a second section 52b, and a middle section 52c located between the first section 52a and the second section 52b. Preferably, the shaft 58 is inserted through the middle portion 50c of the synchronizer 50 and the middle section 52c of the latch 52 to pivot the synchronizer 50 and the latch 52 on the longitudinal wall 42 of the second rail 24.

The elastic structure 56 is used to provide elastic force to one of the synchronizer 50 and the latch 52. Here, the elastic structure 56 is an elastic sheet, and the elastic structure 56 includes a first elastic pin 56a and a second elastic pin 56b, which are used to provide elastic force to the synchronizer 50 and the latch 52 respectively, but the implementation is not limited. Preferably, the first elastic pin 56a and the second elastic pin 56b contact the second portion 50b of the synchronizer 50 and the second section 52b of the latch 52 respectively.

The auxiliary member 54 can move linearly relative to the second rail 24, and here, longitudinal movement (X-axis direction) is taken as an example. Preferably, the auxiliary member 54 and the second rail 24 (the longitudinal wall 42) are arranged with at least one first limiting feature 60 and at least one second limiting feature 62 that match each other. For example, the first limiting feature 60 is a longitudinal hole, and the second limiting feature 62 is a part of a protrusion (such as a pin or nail) that penetrates the longitudinal hole, but it is not limited in implementation.

Preferably, the slide rail assembly 20 further includes an elastic member 64 for providing elastic force to the auxiliary member 54. The elastic member 64 is connected between the second rail 24 and the auxiliary member 54. Here, the elastic member 64 is integrated into the auxiliary member 54 as an example, but the implementation is not limited. One end 64a of the elastic member 64 is connected to the longitudinal wall 42 of the second rail 24.

Preferably, the auxiliary member 54 has a first end 54a and a second end 54b which are located opposite to each other; the first end 54a is connected to the elastic member 64; an auxiliary portion 66 is arranged adjacent to the first end 54a, and the auxiliary portion 66 is, for example, a vertical wall; and a guide portion 68 is arranged adjacent to the second end 54b, and the guide portion 68 is, for example, an inclined surface or an arc surface, but is not limited in implementation. The auxiliary portion 66 is used in conjunction with the blocking feature 30 on the first rail 22, and the guide portion 68 is used in conjunction with the second portion 50b of the synchronizer 50.

As shown in FIG. 6 and FIG. 7 , the slide rail assembly 20 is in a retracted state, and the second rail 24 and the third rail 26 are in a retracted position R relative to the first rail 22. The latch 52 and the predetermined component 38 (the predetermined feature 28 ) have a first longitudinal distance; the auxiliary member 54 and the blocking feature 30 have a second longitudinal distance, and the auxiliary member 54 is in a first auxiliary position M1 relative to the second rail 24 . In addition, the first elastic foot 56a contacts and applies elastic force to the second portion 50b of the synchronous member 50, and the second elastic foot 56b contacts and applies elastic force to the second section 52b of the latch member 52; on the other hand, the first portion 50a of the synchronous member 50 and the first section 52a of the latch member 52 both abut against the longitudinal wall 48 of the third rail 26. The second section 52b of the latch member 52 is provided with a hook 70.

As shown in FIG8 , when the third rail 26 is displaced from the folded position R to an opening direction D1, the third rail 26 can synchronously drive the second rail 24 to displace relative to the first rail 22 to the opening direction D1 through the mutual contact between the working feature 45 and the synchronizer 50 in the first state S1.

Specifically, when the third rail 26 is displaced in the opening direction D1, the working feature 45 of the third rail 26 corresponds to an extension section 72 of the first portion 50a of the synchronizer 50. On the other hand, the synchronizer 50 responds to the elastic force of the first elastic foot 56a and can be in the first state S1. At this time, the extension section 72 and the working feature 45 of the third rail 26 are in contact with each other (or hooked against each other), so that the third rail 26 can synchronously drive the second rail 24 to displace in the opening direction D1.

As shown in FIGS. 9 to 11 , when the third rail 26 and the second rail 24 are synchronously displaced to a predetermined position in the opening direction D1, the blocking feature 30 and the auxiliary portion 66 of the auxiliary member 54 contact each other to generate a force F. For example, the blocking feature 30 is used to block the auxiliary portion 66 of the auxiliary member 54, so that the auxiliary member 54 can move longitudinally from the first auxiliary position M1 (as shown in FIG. 10 ) to a second auxiliary position M2 relative to the second rail 24 in response to the force F. The auxiliary member 54 contacts the second portion 50b of the synchronizer 50 through the guide portion 68 and overcomes the elastic force of the first elastic foot 56a to drive the synchronizer 50 to move (pivot) from the first state S1 to a second state S2 (as shown in FIG. 11 ), so that the extension section 72 of the synchronizer 50 no longer contacts the working feature 45 of the third rail 26, thereby releasing the synchronous displacement relationship between the third rail 26 and the second rail 24.

As shown in Figures 12 and 13, when the auxiliary member 54 is in the second auxiliary position M2 relative to the second rail 24, the second rail 24 can be stopped at an extended position E through the mutual blocking of the blocking feature 30 and the auxiliary portion 66 of the auxiliary member 54, that is, the second rail 24 is in the extended position E relative to the first rail 22. Furthermore, the third rail 26 can continue to move in the opening direction D1 relative to the second rail 24 in the extended position E, so that the longitudinal wall 48 of the third rail 26 no longer abuts against the first section 52a of the latch 52, so that the second section 52b of the latch 52 responds to the elastic force of the second elastic foot 56b to allow the hook 70 of the latch 52 to latch to the predetermined feature 28, so as to prevent the second rail 24 from moving from the extended position E to a folding direction D2 relative to the first rail 22. At this time, the slide rail assembly 20 is in an extended state.

It is worth mentioning that the third rail 26 has a first end 26a and a second end 26b, such as a front end and a rear end. When the third rail 26 returns from a predetermined extension position K to the folding direction D2 to the folding position R, a portion of the third rail 26 (such as the second end 26b) can contact the first section 52a of the latch 52 to drive the hook 70 of the latch 52 to no longer be latched to the predetermined feature 28, so as to allow the second rail 24 to move from the extension position E to the folding direction D2 relative to the first rail 22.

In addition, as shown in FIG. 10 and FIG. 14 , there is inevitably a lateral installation tolerance between the second rail 24 and the first rail 22 . For example, the second rail 24 (the longitudinal wall 42) and the first rail 22 (the longitudinal wall 34) have an ideal first transverse distance T1 (as shown in FIG. 10) therebetween. When the installation tolerance exists, the first transverse distance T1 between the second rail 24 (the longitudinal wall 42) and the first rail 22 (the longitudinal wall 34) may become a second transverse distance T2 (as shown in FIG. 14) different from (for example, greater than) the first transverse distance T1 due to unexpected factors. However, since the auxiliary portion 66 of the auxiliary member 54 on the second rail 24 and the blocking feature 30 on the first rail 22 are both vertically arranged in a transverse direction, Therefore, even if the second rail 24 (the longitudinal wall 42) and the first rail 22 (the longitudinal wall 34) are at the second lateral distance T2, when the third rail 26 and the second rail 24 are synchronously displaced relative to the first rail 22 in the opening direction D1, the reliability of the mutual contact between the blocking feature 30 and the auxiliary portion 66 of the auxiliary member 54 is not easily affected, and the force F can be generated to enable the auxiliary member 54 to move and drive the synchronizer 50 from the first state S1 to the second state S2, so as to ensure that the synchronous displacement relationship between the third rail 26 and the second rail 24 can be released. Since the operation principle of this part is essentially the same as Figure 11 and its description, it will not be elaborated here for the sake of brevity.

It can be seen that the slide rail assembly 20 of the embodiment of the present invention includes this feature: when the third rail 26 (such as the inner rail) and the second rail 24 (such as the middle rail) are synchronously displaced relative to the first rail 22 (such as the outer rail) in the opening direction D1, through the mutual contact between the auxiliary portion 66 of the auxiliary member 54 and the blocking feature 30 on the first rail 22, the auxiliary member 54 on the second rail 24 can drive the synchronous member 50 on the second rail 24 from the first state S1 to the second state S2, so that the extension section 72 of the synchronous member 50 no longer contacts the working feature 45 of the third rail 26, so as to ensure that the synchronous displacement relationship between the third rail 26 and the second rail 24 can be released.

Although the present invention has been disclosed by the above preferred embodiments, they are not intended to limit the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of the attached patent application.
