Description

Technical Field

[0001] This invention relates to a slide rail assembly that is reliable in use. Background Technology

[0002] For example, US Patent Publication No. 6,851,773B2 discloses a sliding aid positioning structure for a drawer slide, which includes a first rail, a second rail, a sliding aid, and a positioning member. The sliding aid is movably installed between the first rail and the second rail, and a slot is provided at the front end of the sliding aid; the positioning member is disposed at the passage opening of the first rail. When the second rail is displaced relative to the first rail in an opening direction and removed from the passage of the first rail, the positioning member can be engaged with the slot of the sliding aid through a flexible hook (hook portion) to prevent the sliding aid from sliding arbitrarily relative to the first rail, thus contributing to the support or stability of the second rail as it re-inserts into the passage of the first rail.

[0003] For example, US Patent Publication No. 7,648,214B2 discloses a sliding rail bearing carrier positioning device, which includes a carrier rail, a sliding rail, and a bearing carrier. The front end of the carrier rail is provided with a support seat for the sliding rail to slide against. A hook is provided at the support seat, which is pivotally connected to a stop and can swing. The stop is fixed to the front end of the carrier rail and partially covers the support seat. A slot is formed on the support seat, and a spring rod is formed on one side of the slot, providing elastic force to allow the hook to return to its original position. The bearing carrier is disposed between the sliding rail and the carrier rail, and has balls as the sliding medium between the sliding rail and the carrier rail. Its front end is provided with a protruding hook. Accordingly, when the bearing carrier moves to the support seat, its front end is pressed against the stop and positioned by the hook of the protruding hook.

[0004] Although the aforementioned patents have revealed the relevant technical features of the sliding component positioning structure and the bearing carrier positioning device, the question of how to develop a different slide rail product has become an issue that cannot be ignored due to different market demands.

[0039] 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, a second rail 24, a sliding aid device 26, and a working member 28. Preferably, it also includes a third rail 30. The first rail 22 is movably mounted between the third rail 30 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 30. In this embodiment, the third rail 30 (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 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 side direction of the slide rail), and the Z-axis is the vertical direction (or the height direction of the slide rail).

[0040] The first track 22 includes a channel 32. Preferably, the first track 22 includes a first wall 34a, a second wall 34b, and a longitudinal wall 36, the 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 the channel 32. The first track 22 has a front end 22a and a rear end 22b.

[0041] The second rail 24 is movably installed in the channel 32 of the first rail 22, and the second rail 24 is longitudinally displaceable relative to the first rail 22. The second rail 24 includes a first wall 38a, a second wall 38b, and a longitudinal wall 40, the longitudinal wall 40 connecting the first wall 38a and the second wall 38b of the second rail 24. The second rail 24 includes a release feature 37, such as a protrusion, and the release feature 37 includes a first guide structure 39a and a second guide structure 39b; the first guide structure 39a and the second guide structure 39b are inclined surfaces or curved surfaces, but are not limited in implementation.

[0042] The sliding aid device 26 is movably mounted between the first rail 22 and the second rail 24, and the sliding aid device 26 includes a locking feature 42, such as a hook. Preferably, the sliding aid device 26 further includes a first part 44a, a second part 44b, and a longitudinal part 46, the longitudinal part 46 connecting the first part 44a and the second part 44b, and the first part 44a, the second part 44b, and the longitudinal part 46 respectively corresponding to the first wall 34a, the second wall 34b, and the longitudinal wall 36 of the first rail 22; the first part 44a and the second part 44b of the sliding aid device 26 are each arranged with a plurality of ball bearings 48 (due to the viewing angle, Figure 1 and Figure 2 The diagram only shows the balls 48 on the second part 44b. The balls 48 on the first part 44a and the balls 48 on the second part 44b are used to support the first wall 34a and the second wall 34b of the first rail 22, and the first wall 38a and the second wall 38b of the second rail 24, respectively. This helps to improve the smoothness of the displacement of the second rail 24 and the first rail 22 relative to each other.

[0043] like Figure 2 , Figure 3 and Figure 4 As shown, the working piece 28 is arranged on the longitudinal wall 36 of the first rail 22, and the working piece 28 is adjacent to the front end 22a of the first rail 22. The working piece 28 includes a main body 50, an elastic part 52, and a predetermined part 54 (this part can be referred to in conjunction with the previous section). Figure 2A ).

[0044] Preferably, the working part 28 is movably mounted on the longitudinal wall 36 of the first rail 22. For example, the main body 50 of the working part 28 is pivotally connected to the longitudinal wall 36 of the first rail 22 via a shaft 56, but the implementation is not limited to this.

[0045] The elastic part 52 is used to support the main body part 50. The elastic part 52 is, for example, an elastic arm, but is not limited in implementation; the pre-determined part 54 is connected to the main body part 50.

[0046] Preferably, the longitudinal wall 36 of the first track 22 is provided with a support 58 to support the elastic part 52 of the working piece 28 (e.g., Figure 3 and Figure 4 (As shown).

[0047] Preferably, the main body 50 of the working piece 28 has a first end E1 and a second end E2 positioned opposite each other; the predetermined part 54 is adjacent to the first end E1 of the main body 50 (e.g., Figure 2A (As shown).

[0048] Preferably, the elastic portion 52 of the working piece 28 has a first segment 60a and a second segment 60b extending from the first segment 60a; wherein the first segment 60a connects to the main body portion 50 and is adjacent to the second end E2 of the main body portion 50, and a predetermined space J is defined between the second segment 60b and the main body portion 50 (e.g., ...). Figure 2A (As shown). When the workpiece 28 is in a first state S1, the main body 50 of the workpiece 28 and the second segment 60b of the elastic part 52 maintain a distance G through the predetermined space J.

[0049] Preferably, the predetermined portion 54 of the workpiece 28 includes a first guide feature 62, a second guide feature 64, and a hole 66 located between the first guide feature 62 and the second guide feature 64. The first guide feature 62 and the second guide feature 64 are inclined surfaces or arc surfaces, and the hole 66 is defined by a plurality of hole walls. For example, the predetermined portion 54 includes a first hole wall 68a, a second hole wall 68b, a third hole wall 68c, and a fourth hole wall 68d, which together define the hole 66 (e.g., ...). Figure 2A (As shown).

[0050] Preferably, the main body 50, the elastic part 52, and the predetermined part 54 can be integrated into one unit, making the working part 28 a single component (e.g., Figure 2A (As shown).

[0051] like Figure 4 As shown, the locking feature 42 of the sliding aid device 26 has a guide section 70, which is an inclined surface or an arc surface. On the other hand, the working piece 28 is in the first state S1, and the support portion 58 of the longitudinal wall 36 of the first rail 22 is used to support at least a portion of the second section 60b of the elastic portion 52 of the working piece 28. In addition, the predetermined portion 54 of the working piece 28 is arranged with an extension 72 adjacent to the hole 66, for example, the extension 72 extends from the first hole wall 68a toward the second wall 34b of the first rail 22.

[0052] When the second rail 24 moves relative to the first rail 22 from a retracted position to an opening direction D1 to a predetermined stroke, the release feature 37 contacts the first guide feature 62 through the first guide structure 39a, allowing the release feature 37 to easily pass over the predetermined portion 54 of the working piece 28. The sliding device 26 also moves in the opening direction D1 in response to the displacement of the second rail 24. During this process, the locking feature 42 (guide section 70) of the sliding device 26 will contact the first guide feature 62 of the predetermined portion 54 of the working piece 28. 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.

[0053] like Figure 5 As shown, when the second rail 24 continues to move in the opening direction D1 relative to the first rail 22, the contact between the locking feature 42 (guide section 70) of the sliding device 26 and the first guide feature 62 of the predetermined part 54 of the working piece 28 can generate a force to drive the working piece 28, so that the working piece 28 moves from the first state S1 to a second state S2, for example, from the first state S1 to a predetermined rotation direction R to the second state S2. At this time, the working piece 28 accumulates an elastic force through the elastic part 52.

[0054] Preferably, the mutual support between the support portion 58 of the longitudinal wall 36 of the first rail 22 and the second segment 60b of the elastic portion 52 of the working piece 28 can serve as a support point, which helps the working piece 28 to pivot from the first state S1 to the second state S2. During the pivoting process of the working piece 28 to the second state S2, the main body portion 50 of the working piece 28 and the second segment 60b of the elastic portion 52 can approach each other through the predetermined space J, and the first segment 60a of the elastic portion 52 of the working piece 28 is tilted at a predetermined angle relative to the second segment 60b (or the support portion 58 of the longitudinal wall 36 of the first rail 22), so that the working piece 28 accumulates the elastic force through the elastic portion 52.

[0055] Preferably, the working part 28 further includes a bent section 55 extending from the first end E1 of the main body 50, and the longitudinal wall 36 of the first rail 22 is provided with a corresponding space 57, which allows the bent section 55 to pass through, so that the longitudinal wall 36 of the first rail 22 can provide support for the bent section 55, which helps the stability of the working part 28 during movement (e.g., pivoting).

[0056] like Figure 6 and Figure 7As shown, when the second rail 24 is further displaced in the opening direction D1 relative to the first rail 22 and is unloaded from the channel 32 of the first rail 22, the sliding device 26 moves to a predetermined position K adjacent to the front end 22a of the first rail 22, and the sliding device 26 can be engaged with the hole 66 of the predetermined part 54 of the working piece 28 through the locking feature 42.

[0057] Specifically, when the sliding aid device 26 is in the predetermined position K, the locking feature 42 of the sliding aid device 26 aligns with the hole 66 of the predetermined part 54, and the working member 28 releases the elastic force through the elastic part 52, causing the working member 28 to return from the second state S2 to the first state S1 (e.g., locked state). The sliding aid device 26 extends into the hole 66 of the predetermined part 54 of the working member 28 through the locking feature 42. The locking feature 42 aligns with the first hole wall 68a (and the extension 72) to prevent the sliding aid device 26 from arbitrarily displacing relative to the first rail 22. For example, the first hole wall 68a (and the extension 72) can block the locking feature 42 to prevent the sliding aid device 26 from displacing relative to the first rail 22 from the predetermined position K in a retraction direction D2 (e.g., ...). Figure 6 (As shown).

[0058] like Figure 8 As shown, the sliding aid 26 is in the predetermined position K, and the working part 28 is in the first state S1 (e.g., locked state), which can be used to lock the locking feature 42 of the sliding aid 26. When the second rail 24 is reinserted into the channel 32 of the first rail 22 from outside the channel 32 of the first rail 22 in the retraction direction D2, the first wall 38a and the second wall 38b of the second rail 24 can be pre-supported by the ball bearings 48 of the first part 44a and the second part 44b of the sliding aid 26, respectively. This helps to improve the stability or smoothness of the second rail 24 when it is inserted into the channel 32 of the first rail 22 in the retraction direction D2.

[0059] like Figure 9 , Figure 10 and Figure 11 As shown, when the second rail 24 continues to be inserted into the channel 32 of the first rail 22 in the retraction direction D2, the second rail 24 can drive the working piece 28 through the release feature 37, so that the locking feature 42 of the sliding device 26 is released from the hole 66 of the predetermined part 54 of the working piece 28, so as to allow the sliding device 26 to move from the predetermined position K to the retraction direction D2.

[0060] Specifically, as the second rail 24 continues to be inserted into the channel 32 of the first rail 22 in the retracting direction D2, the second guide structure 39b of the release feature 37 of the second rail 24 will contact the second guide feature 64 of the predetermined part 54 of the working piece 28, generating another force that can drive the working piece 28, causing the working piece 28 to move from the first state S1 (e.g., the locked state, such as...) Figure 9 As shown) the activity is moved to the second state S2 (e.g., the unlocked state, such as...). Figure 10 As shown), for example, from the first state S1 to the predetermined rotation direction R, the pivot is rotated to the second state S2, causing the locking feature 42 of the sliding device 26 to disengage from the hole 66 of the predetermined part 54 of the working member 28.

[0061] Preferably, the mutual support between the support portion 58 of the longitudinal wall 36 of the first track 22 and the second segment 60b of the elastic portion 52 of the working piece 28 can serve as a support point, which helps the working piece 28 to move from the first state S1 (as in...) Figure 9 (As shown) pivot to the second state S2 (as shown) Figure 10 As shown), during the process of the working piece 28 pivoting to the second state S2, through the predetermined space J, the main body 50 of the working piece 28 and the second segment 60b of the elastic part 52 can approach each other (as shown). Figure 10 As shown), the first segment 60a of the elastic part 52 of the working piece 28 is tilted at a predetermined angle relative to the second segment 60b (or the support part 58 of the longitudinal wall 36 of the first rail 22), so that the working piece 28 accumulates an elastic force through the elastic part 52.

[0062] When the second rail 24 moves further relative to the first rail 22 in the retraction direction D2, the sliding aid device 26 responds to the displacement of the second rail 24 and can move from the predetermined position K in the retraction direction D2, and the elastic part 52 of the working member 28 releases the elastic force, so that the working member 28 can move from the second state S2 (as shown in the image). Figure 10 As shown) Restored to the first state S1 (as shown) Figure 11 (As shown).

[0063] It is worth mentioning that, such as Figure 9As shown, the size of the hole 66 in the predetermined part 54 is substantially larger than the size of the latching feature 42 in the sliding device 26. Specifically, a longitudinal dimension of the hole 66 is defined between the first hole wall 68a and the second hole wall 68b, and the longitudinal dimension of the hole 66 is substantially larger (or slightly larger) than the longitudinal dimension of the latching feature 42 (e.g., a hook), so that the hole 66 has a predetermined looseness when accommodating the latching feature 42. According to this configuration, when the second rail 24 is inserted into the channel 32 of the first rail 22 in the retraction direction D2, and the second rail 24 drives the working piece 28 from the first state S1 to the second state S2 through the release feature 37 (the second guide structure 39b), due to the predetermined looseness, the locking feature 42 of the sliding device 26 can be easily released from the hole 66 of the predetermined part 54 of the working piece 28. Therefore, it avoids the problem that the locking feature 42 and the hole wall of the hole 66 (such as the first hole wall 68a and the second hole wall 68b) are locked too tightly and difficult to release each other, or that they are locked due to excessive locking and may deform or be damaged when the locking feature 42 and the predetermined part 54 of the working piece 28 are locked.

[0064] Therefore, the slide rail assembly 20 of the present invention has the following characteristics:

[0065] 1. When the predetermined portion 54 of the working piece 28 is subjected to an external force (such as the force described above), since the working piece 28 can move relative to the first rail 22 (e.g., pivot), and the working piece 28 has elasticity through the elastic portion 52, the external force can be mitigated to prevent the predetermined portion 54 of the working piece 28 from deforming due to the force, which helps to improve the reliability of the slide rail assembly 20 in use.

[0066] 2. The size of the hole 66 in the pre-determined part 54 is substantially larger than the size of the locking feature 42 of the sliding device 26.

[0067] 3. The main body 50, the elastic part 52 and the predetermined part 54 can be integrated into one unit, so that the working part 28 becomes a single component.

[0068] 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.
