Abstract

The present invention relates to a slide rail assembly, which comprises a first rail, a second rail, a slide assisting device, an elastic member and a working member. The second rail is capable of moving relative to the first rail. The elastic member is arranged in the slide assisting device. The working member is arranged in the second rail. During the movement of the second rail relative to the first rail in an opening direction, the working member contacts the elastic member in an initial state to drive the slide assisting device to a predetermined position in the opening direction. When the slide assisting device is in the predetermined position, the elastic member releases an elastic force through a predetermined space of the first rail, so that the elastic member is no longer in the initial state and the working member no longer contacts the elastic member.

Description

Technical Field

[0002] US Patent Publication No. 9,980,566 B2 discloses a slide rail assembly comprising a first rail, a second rail, a stop, a ball retainer, and a stop element. The second rail is movable relative to the first rail; the stop is disposed on the first rail and has a backing portion; the ball retainer is used to facilitate the movement between the second rail and the first rail, the ball retainer has a contact portion, the contact portion of the ball retainer is a fixed part (non-movable part); the stop can be operated relative to the second rail from a first state to a second state; when the stop is in the first state, the stop can push the ball retainer with the contact portion according to the movement of the second rail in an opening direction, until the stop abuts against the backing portion of the stop, at which time a locking feature of the ball retainer will engage with a spring foot on the stop of the first rail, so that the ball retainer can be temporarily held and stopped at a predetermined position, and the positions of the contact portion of the ball retainer and the backing portion of the stop are "misaligned".

[0038] like Figure 1 and Figure 2 As shown, a slide rail assembly 20 according to an embodiment of the present invention includes a first rail 22 and a second rail 24. Preferably, it also includes a third rail 26. The first rail 22 is movably mounted between the third rail 26 and the second rail 24, and the first rail 22 can be used to extend the displacement stroke of the second rail 24 relative to the third rail 26. In this embodiment, the third rail 26 (e.g., the outer rail), the first rail 22 (e.g., the middle rail), and the second rail 24 (e.g., the inner rail) can be longitudinally displaced relative to each other. Figure 1 and Figure 2 In this diagram, the X-axis is the longitudinal direction (or the length direction of the slide rail), the Y-axis is the transverse direction (or the lateral direction of the slide rail), and the Z-axis is the vertical direction (or the height direction of the slide rail).

[0039] The third track 26 includes a first wall 28a, a second wall 28b, and a longitudinal wall 30 connected between the first wall 28a and the second wall 28b of the third track 26. The first wall 28a, the second wall 28b, and the longitudinal wall 30 of the third track 26 together define a channel 32 for accommodating the first track 22. The third track 26 has a front portion 26a and a rear portion 26b.

[0040] The first track 22 includes a first wall 34a, a second wall 34b, and a longitudinal wall 36 connecting the first wall 34a and the second wall 34b of the first track 22. The first wall 34a, the second wall 34b, and the longitudinal wall 36 of the first track 22 together define a channel 38 for accommodating the second track 24. The first track 22 has a front portion 22a and a rear portion 22b.

[0041] The second track 24 includes a first wall 40a, a second wall 40b, and a longitudinal wall 42 connecting the first wall 40a and the second wall 40b of the second track 24. The second track 24 has a front portion 24a and a rear portion 24b.

[0042] Preferably, at least one sliding element 44 is arranged within the channel 32 of the third rail 26. The sliding element 44 includes a plurality of ball bearings, which facilitates the smoothness of the relative displacement between the first rail 22 and the third rail 26. Furthermore, the slide rail assembly 20 also includes a sliding device 46 movably mounted between the first rail 22 and the second rail 24. More specifically, the sliding device 46 is arranged within the channel 38 of the first rail 22, and the sliding device 46 includes a plurality of rolling elements 48, such as ball bearings (this part can also be referred to in conjunction with...). Figure 3 This helps to improve the smoothness of the relative displacement between the second rail 24 and the first rail 22.

[0043] Preferably, the sliding device 46 includes a body 33, on which the rolling elements 48 are arranged, and which are used to support the first rail 22 and the second rail 24.

[0044] like Figure 3 As shown, the first track 22 includes a blocking feature 50 and a predetermined space 52. The blocking feature 50 is located within the channel 38 of the first track 22.

[0045] Preferably, the blocking feature 50 is, for example, a protrusion that protrudes laterally (or laterally) relative to the longitudinal wall 36 of the first track 22, but the implementation is not limited to this. Here, we take the example of the blocking feature 50 being located at the front part 22a of the adjacent first track 22.

[0046] Preferably, the longitudinal wall 36 of the first track 22 has the predetermined space 52. For example, the longitudinal wall 36 of the first track 22 includes a groove to form the predetermined space 52; or, in this embodiment, the predetermined space 52 is an opening, but the implementation is not limited. In this embodiment, the predetermined space 52 laterally connects a first side L1 and a second side L2 of the longitudinal wall 36 of the first track 22, wherein the first side L1 and the second side L2 are two opposite sides. The first side L1 of the longitudinal wall 36 of the first track 22 faces the longitudinal wall 30 of the third track 26, and the second side L2 of the longitudinal wall 36 of the first track 22 faces the longitudinal wall 42 of the second track 24 (this part can also be referred to in conjunction with the above). Figure 1 ).

[0047] Preferably, the sliding device 46 is located within the channel 38 of the first track 22.

[0048] Preferably, the main body 33 of the sliding aid device 46 includes a first part 54a, a second part 54b, and a longitudinal part 56 connected between the first part 54a and the second part 54b of the main body 33. The rolling elements 48 are arranged between the first part 54a and the second part 54b of the main body 33 (due to the viewing angle). Figure 3Only the rolling element 48 on the second part 54b of the main body 33 is shown, while the rolling element 48 on the first part 54a of the main body 33 is not shown. The first part 54a, the second part 54b and the longitudinal part 56 correspond to the first wall 34a, the second wall 34b and the longitudinal wall 36 of the first rail 22, respectively.

[0049] The slide rail assembly 20 also includes an elastic element 58 arranged in the main body 33 of the sliding aid device 46. In this embodiment, the elastic element 58 and the main body 33 are two independent components, but the implementation is not limited.

[0050] Preferably, the elastic member 58 is arranged in the longitudinal portion 56 of the main body 33. The elastic member 58 includes a connecting portion 60, an elastic portion 62, and a predetermined portion 64. The connecting portion 60 of the elastic member 58 is connected (e.g., fixed) to the longitudinal portion 56 of the main body 33. The elastic portion 62 extends from the connecting portion 60, and the predetermined portion 64 is located on the elastic portion 62. The predetermined portion 64 is, for example, a protrusion protruding relative to the elastic portion 62, but is not limited in implementation. The elastic member 58 can be in an initial state K1 and accumulate an elastic force F by mutual support between the elastic portion 62 and the longitudinal wall 36 of the first track 22.

[0051] Preferably, the longitudinal portion 56 of the main body 33 has a space 65 (e.g., an opening) connecting the two sides of the longitudinal portion 56 of the main body 33; the elastic portion 62 passes through the space 65 and supports itself against the longitudinal wall 36 of the first track 22, so that the elastic portion 62 is in the initial state K1 and accumulates the elastic force F.

[0052] Preferably, the slide rail assembly 20 further includes a locking member 66 disposed on the first rail 22. The locking member 66 includes a fixing part 68 and a flexible arm 70. The fixing part 68 is fixed to the longitudinal wall 36 of the first rail 22; the flexible arm 70 extends from the fixing part 68 and has a fastening segment 72. On the other hand, the main body 33 of the sliding aid device 46 also includes a fastening part 74 for use in conjunction with the fastening segment 72. The fastening part 74 is located at the front end adjacent to the main body 33, but the implementation is not limited.

[0053] like Figure 4 As shown, the slide rail assembly 20 also includes a working member 76 arranged on the second rail 24. Furthermore, the working member 76 is movably mounted on the second rail 24, for example, the working member 76 is pivotally connected to the second rail 24 via a shaft 78.

[0054] Preferably, the slide rail assembly 20 further includes an operating member 80 and an auxiliary seat 82. The operating member 80 is used to operate the working piece 76. The operating member 80 is movably mounted on the second rail 24. For example, the operating member 80 can be displaced relative to the second rail 24 along the length direction of the second rail 24. The second rail 24 includes at least one retaining feature 84, which can be used to support the operating member 80 to improve the stability of the operating member 80 when it is operated and displaced.

[0055] Preferably, the operating member 80 includes an operating part 86a, a driving part 86b, and an extension part 86c connected between the operating part 86a and the driving part 86b.

[0056] Preferably, the auxiliary seat 82 is arranged on the second rail 24, and the auxiliary seat 82 is used to provide elastic force to the working piece 76. Here, taking the auxiliary seat 82 including an elastic segment 88, and the elastic segment 88 being used to provide elastic force to the working piece 76 as an example, the working piece 76 can be maintained in a first state S1 in response to the elastic force of the elastic segment 88.

[0057] like Figure 5 As shown, the first rail 22 extends relative to the third rail 26, and the front portion 22a of the first rail 22 extends beyond the front portion 26a of the third rail 26. The working member 76 can be maintained in the first state S1 in response to the elastic force of the elastic segment 88 of the auxiliary seat 82.

[0058] like Figure 5 , Figure 6 and Figure 7 As shown, when the second track 24 ( Figure 6 and Figure 7 During the displacement of the second track 24 relative to the first track 22 from a closed position to an open direction D1, the working piece 76 in the first state S1 will contact the predetermined part 64 of the elastic member 58 in the initial state K1 (e.g., ...). Figure 5 and Figure 6 As shown), it is used to forcibly drive the sliding device 46 in the opening direction D1 to a predetermined position P (as shown). Figure 7 (As shown). When the sliding device 46 is in the predetermined position P, the elastic member 58 releases the elastic force F through the predetermined space 52 of the first rail 22, causing the elastic member 58 to move from the initial state K1 (as shown). Figure 5 and Figure 6 (As shown) transition to a non-initial state K2 (e.g.) Figure 7 (As shown), so that the working part 76 no longer contacts the elastic member 58.

[0059] Furthermore, as the second rail 24 moves relative to the first rail 22 in the opening direction D1, the working piece 76 will contact the predetermined portion 64 on the elastic portion 62 of the elastic member 58 (e.g., Figure 5 and Figure 6 As shown), this is used to forcibly move the sliding aid 46 in the opening direction D1, thereby ensuring that the sliding aid 46 can be close to the front part 22a of the first rail 22. The advantage of this is, for example, that it ensures that the first wall 40a and the second wall 40b of a predetermined section of the second rail 24 (e.g., the middle section and / or the rear section, but not limited in implementation) can be well supported by the sliding aid 46 (the rolling element 48). Figure 5 (As shown).

[0060] When the sliding aid device 46 is forcibly moved to a predetermined position P (e.g., Figure 7 When (as shown), the elastic portion 62 of the elastic member 58 releases the elastic force F through the predetermined space 52 of the longitudinal wall 36 of the first rail 22, causing the elastic portion 62 of the elastic member 58 to move from the initial state K1 (as shown). Figure 5 and Figure 6 (As shown) Move laterally (or sideways) to this non-initial state K2 (e.g.) Figure 7 As shown), the working piece 76 is offset from the predetermined portion 64 on the elastic portion 62 of the elastic member 58, so that the working piece 76 no longer contacts the predetermined portion 64 on the elastic portion 62 of the elastic member 58.

[0061] like Figure 8 , Figure 9 and Figure 10 As shown, when the second track 24 ( Figure 8 and Figure 9 (The second rail 24 is omitted from the drawing) When the second rail 24 continues to move relative to the first rail 22 in the opening direction D1 to an extended position E, the blocking feature 50 of the first rail 22 can block the working piece 76 in the first state S1, thereby preventing the second rail 24 from moving from the extended position E to the opening direction D1 (e.g., Figure 9 and Figure 10 (As shown).

[0062] Preferably, when the second rail 24 continues to move relative to the first rail 22 in the opening direction D1 to the extended position E, the sliding aid device 46 also moves (differentially displaces) along with the second rail 24 in the opening direction D1 by a predetermined distance J (e.g., Figure 8 and Figure 9 As shown), the latching member 66 (the latching segment 72) is used to latch the sliding device 46 (the latching part 74), so that the sliding device 46 can be temporarily held in a position close to the front part 22a of the first rail 22 (as shown). Figure 10 (As shown).

[0063] It is worth mentioning that the aforementioned differential displacement refers to the fact that when the second rail 24 is displaced relative to the first rail 22, the rolling element 48 of the sliding device 46 will roll in response to the displacement of the second rail 24, thereby allowing the sliding device 46 to move in a manner where the displacement is smaller than the actual displacement of the second rail 24. Since this part falls within the technical scope that is easily understood by those skilled in the art, it will not be elaborated upon here for the sake of simplicity.

[0064] Furthermore, the second rail 24 can be displaced relative to the first rail 22 from the extension position E in a retracting direction D2. During this displacement, the second rail 24 passes through a predetermined feature 90 or a predetermined portion (e.g., an inclined surface or a curved surface, such as...) Figure 10 As shown, the locking element 66 (fastening segment 72) and the sliding aid device 46 (fastening portion 74) can be released from their mutual locking relationship. For example, the predetermined feature 90 can cause the elastic arm 70 of the locking element 66 to swing at an angle, thereby releasing the locking element 66 (fastening segment 72) and the sliding aid device 46 (fastening portion 74). Since this part is within the technical scope that can be understood by those skilled in the art, it will not be described in detail here for the sake of simplicity. Furthermore, once the locking relationship between the locking member 66 (the latching segment 72) and the sliding device 46 (the latching part 74) is released, the rolling member 48 of the sliding device 46 will roll in response to the displacement of the second rail 24 in the closing direction D2, thereby causing the sliding device 46 to move in the closing direction D2 (differential displacement). During this process, the elastic member 58 (the elastic part 62) can leave the predetermined space 52 of the first rail 22, so that the elastic member 58 returns from the non-initial state K2 to the aforementioned initial state K1.

[0065] like Figure 10 and Figure 11 As shown, the operating element 80 can be used to drive the working piece 76 from the first state S1 (e.g., Figure 10 (As shown) transitions to a second state S2 (as shown) Figure 11 As shown), the blocking feature 50 of the first rail 22 and the working piece 76 no longer block each other, so as to allow the second rail 24 to move from the extension position E to the opening direction D1.

[0066] Furthermore, the user can apply an operating force F' to the operating part 86a of the operating member 80, causing the operating member 80 to move from a first operating position X1 (e.g., Figure 10 (As shown) Displaced to a second operating position X2 (e.g.) Figure 11 As shown), the driving part 86b of the operating member 80 drives the working member 76 from the first state S1 (as shown). Figure 10 (As shown) pivot to the second state S2 (as shown) Figure 11 As shown), this prevents the blocking feature 50 of the first rail 22 from obstructing the working piece 76, allowing the second rail 24 to move from the extension position E towards the opening direction D1 and to be unloaded from the channel 38 of the first rail 22 (as shown). Figure 11 (As shown).

[0067] like Figure 12 A first track 200 according to another embodiment of the present invention is illustrated. The difference between this first track 200 and the first track 22 of the above embodiment is that the elastic member 202 is integrated into the main body 33 of the sliding aid device 46. Accordingly, the same technical effect as the above embodiment can be achieved.

[0068] Based on the above description, it can be seen that the improved efficacy and advantages of the present invention are as follows:

[0069] a. As the second rail 24 moves relative to the first rail 22 in the opening direction D1, the working member 76 contacts the elastic member 58, forcibly driving the sliding device 46 to move in the opening direction D1 to a predetermined position. This ensures that the sliding device 46 can be close to the front part 22a of the first rail 22. For example, this ensures that a predetermined section of the second rail 24 can be well supported by the sliding device 46 (the rolling member 48), thus providing an effective sliding effect for the second rail 24.

[0070] b. The first track 22 (the longitudinal wall 36) has the predetermined space 52, the elastic member 58 is arranged in the sliding device 46, and the elastic member 58 can release the elastic force F through the predetermined space 52 of the first track 22, so that the elastic member 58 can change from the initial state K1 (e.g., move laterally) to the non-initial state K2, so that the working piece 76 no longer contacts the elastic member 58.

[0071] Although the present invention has been described with reference to specific embodiments, those skilled in the art should recognize that the above embodiments are merely illustrative of the invention, and various equivalent changes and modifications can be made without departing from the spirit of the invention. Therefore, any changes or modifications to the above embodiments within the scope of the essential spirit of the invention will fall within the scope of the claims of this application.
