Description

Technical Field

[0001] The invention relates to a slide rail, in particular to a slide rail assembly which can ensure the reliability of two slide rails when they are in a predetermined position relative to each other. Background Art

[0002] For example, a U.S. invention patent case (publication number US 6,935,710 B2) discloses a bidirectional positioning structure of a drawer slide rail, in which a positioning group and a blocking seat are respectively arranged on a first rail and a second rail, and the positioning group is provided with at least two positioning arms and an elastic component that abuts against each other, and the two positioning arms are correspondingly provided with an inclined surface and a first latch portion, and the blocking seat is provided with a blocking portion; when the first rail is pulled to a predetermined operating position, the blocking portion of the blocking seat of the second rail can pass over the inclined surface of one of the positioning arms of the first rail, and be latched between the first latch portions of the two positioning arms to form bidirectional positioning.

[0003] Specifically, as the patent case Figure 4 It can be seen that when the first rail is in an extended position relative to the second rail, the two positioning arms can respectively abut against two sides of a blocking portion of the blocking seat through their respective first latching portions to form the bidirectional positioning. Figure 1 It can be seen that the blocking portion is a protrusion that protrudes upright transversely relative to the blocking seat (or relative to the longitudinal wall or length direction of the second rail), so that the two sides of the blocking portion are upright structures; on the other hand, when the first latching portions of the two positioning arms respectively abut against the two sides of the blocking portion, if the lateral depth of the first latching portions abutting against each side of the corresponding blocking portion (blocking each other) is not enough, it may cause the first rail to be easily detached from each other when it is in the extended position relative to the second rail.

[0004] Therefore, as the current market has stricter requirements on the reliability or safety of the slide rail assembly in use, how to develop a different slide rail product has become a topic worth discussing. Summary of the invention

Preferably, it also includes a third rail 30, and the first rail 22 is movably installed between the third rail 30 and the second rail 24, so that the third rail 30 (such as an outer rail), the first rail 22 (such as a middle rail) and the second rail 24 (such as an inner rail) can form a so-called three-section slide rail assembly 20. The first rail 22, the second rail 24 and the third rail 30 can be longitudinally displaced relative to each other. Figure 1 In the embodiment, the slide rail assembly 20 is in a retracted state, wherein the second rail 24 is in a retracted position R relative to the first rail 22 (and the third rail 30). It is worth mentioning that in this embodiment, 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 lateral direction of the slide rail), and the Z-axis direction is the vertical direction (or the height direction of the slide rail).

[0043] Preferably, the slide rail assembly 20 further includes a second component 32 , an elastic component 34 and at least one operating component, and a first operating component 36 and a second operating component 38 are taken as an example here, but the implementation is not limited thereto.

The first rail 22 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 first rail 22, and the first wall 40a, the second wall 40b and the longitudinal wall 42 of the first rail 22 jointly define another channel for accommodating the second rail 24. The first rail 22 has a first end f1 and a second end r1 away from the first end f1, such as a front end and a rear end, but the implementation is not limited thereto.

[0045] The blocking feature 26 is disposed on one of the first rail 22 and the second rail 24. Here, the blocking feature 26 is disposed on the longitudinal wall 42 of the first rail 22, and the blocking feature 26 is located adjacent to the first end f1 of the first rail 22. However, the blocking feature 26 is not limited in implementation. The blocking feature 26 can be connected to the longitudinal wall 42 of the first rail 22 through a connecting portion 27, or the blocking feature 26 can be directly formed on the first rail 22. The blocking feature 26 is not limited in implementation.

[0046] The second rail 24 and the first rail 22 are longitudinally displaceable relative to each other. The second rail 24 includes a first wall 44a, a second wall 44b and a longitudinal wall 46 connected between the first wall 44a and the second wall 44b of the second rail 24.

[0047] Preferably, at least one sliding aid device is provided between every two slide rails to facilitate the smoothness of the longitudinal displacement of each two slide rails relative to each other. For example, an sliding aid device 47 is movably provided between the second rail 24 and the first rail 22, and the sliding aid device 47 includes a plurality of balls B supported between the first wall 40a of the first rail 22 and the first wall 44a of the second rail 24, and supported between the second wall 40b of the first rail 22 and the second wall 44b of the second rail 24.

[0048] The first member 28 and the second member 32 are disposed on the other of the first rail 22 and the second rail 24. Here, it is taken as an example that both the first member 28 and the second member 32 are disposed on the second rail 24. Preferably, both the first member 28 and the second member 32 are movably mounted on the longitudinal wall 46 of the second rail 24.

[0049] Preferably, the elastic member 34 , the first operating member 36 and the second operating member 38 are all disposed on the longitudinal wall 46 of the second rail 24 .

[0050] Preferably, the elastic member 34 includes an elastic section for providing an elastic force to one of the first member 28 and the second member 32, so that one of the first member 28 and the second member 32 can be maintained in the first state S1. Here, the elastic member 34 includes a first elastic portion 52 and a second elastic portion 54 for providing elastic force to the first member 28 and the second member 32 respectively, so that both the first member 28 and the second member 32 can be maintained in the first state S1 as an example.

[0051] Preferably, the first operating member 36 and the second operating member 38 are respectively used to drive the first component 28 and the second component 32 to no longer be in the first state S1.

[0052] like Figures 3 to 5 As shown, the first member 28 and the second member 32 are pivotally connected to the longitudinal wall 46 of the second rail 24 via a first shaft 48 and a second shaft 50 respectively.

[0053] Preferably, the first operating member 36 is located at a middle rail section adjacent to the second rail 24 ; on the other hand, the second operating member 38 is located at a front rail section adjacent to the first end f2 of the second rail 24 .

[0054] Preferably, when the first member 28 and the second member 32 are in the first state S1, the first member 28 and the second member 32 can respectively abut against the first wall 44a (eg, Figure 4 shown).

[0055] Preferably, the first operating member 36 includes a first driving portion 56, a first operating portion 58 and a first longitudinal extension portion 60 connected between the first driving portion 56 and the first operating portion 58, wherein the first driving portion 56 is used to match a first actuating portion 62 of the first member 28; similarly, the second operating member 38 includes a second driving portion 64, a second operating portion 66 and a second longitudinal extension portion 68 connected between the second driving portion 64 and the second operating portion 66, wherein the second driving portion 64 is used to match a second actuating portion 70 of the second member 32, and the second operating portion 66 is adjacent to the first end f2 (such as Figure 3 , Figure 3A and Figure 5 Preferably, the second driving portion 64 has two driving locations, front and rear, and the second actuating portion 70 also has two contact locations, so that the second driving portion 64 can drive the second actuating portion 70 to move forward or backward.

[0056] Preferably, the second rail 24 is further configured with at least one first holding portion 61 and at least one second holding portion 63 for supporting the first operating member 36 and the second operating member 38 (eg, Figure 4 shown).

[0057] Preferably, the first component 28 has a first predetermined portion 72 , and the second component 32 has a second predetermined portion 74 .

[0058] Preferably, the first component 28 and the second component 32 both have a first side L1 and a second side L2 opposite to each other (eg Figure 3A ). A step structure 76 is disposed between the first side L1 and the second side L2 of the first member 28, and the step structure 76 has a first level 76a and a second level 76b connecting the first level 76a; the first predetermined portion 72 of the first member 28 is located at the second level 76b. Similarly, another step structure 78 is disposed between the first side L1 and the second side L2 of the second member 32, and the other step structure 78 has a first level 78a and a second level 78b connecting the first level 78a; the second predetermined portion 74 of the second member 32 is located at the second level 78b.

[0059] like Figure 6 and Figure 7 As shown, the first member 28 and the second member 32 can be pressed against the first wall 44a of the second rail 24 by the elastic force of the first elastic portion 52 and the second elastic portion 54 respectively and remain in the first state S1 (as shown in FIG. Figure 6 shown).

[0060] Furthermore, the user may apply a first force F1 to the second operating member 38 (the second operating portion 66 thereof) to cause the second operating member 38 to longitudinally displace relative to the second rail 24 (eg, Figure 7 As shown), and through the cooperation of the second driving portion 64 and the second actuating portion 70, the second member 32 can be driven from the first state S1 (as shown Figure 6 ) moves (e.g. pivots) to a second state S2 (e.g. Figure 7 As shown in FIG. 1 , the second member 32 no longer abuts against the first wall 44a of the second rail 24. At this time, the second elastic portion 54 is in a state of accumulating an elastic force. Once the application of the first force F1 stops, the second member 32 responds to the second elastic portion 54 releasing the elastic force and can return to the first state S1 from the second state S2.

[0061] like Figure 8 and Fig. 9 As shown, the user can apply a second force F2 to the first operating member 36 (the first operating portion 58) to cause the first operating member 36 to move longitudinally relative to the second rail 24 (eg Fig. 9 As shown), and through the cooperation of the first driving portion 56 and the first actuating portion 62, the first member 28 can be driven from the first state S1 (as shown Figure 8 ) moves (e.g. pivots) to the second state S2 (e.g. Fig. 9 As shown in FIG. 2 , the first member 28 no longer abuts against the first wall 44a of the second rail 24. At this time, the first elastic portion 52 is in a state of accumulating an elastic force. Once the second force F2 is stopped, the first member 28 responds to the first elastic portion 52 releasing the elastic force and can return to the first state S1 from the second state S2.

[0062] It is worth mentioning that although the above disclosure discloses that the first operating member 36 and the second operating member 38 can respectively drive the first component 28 and the second component 32 from the first state S1 to the second state S2, however, in other alternative embodiments, a single operating member can have two driving parts to drive the first component 28 or the second component 32 from the first state S1 to the second state S2, so the number of the operating members is not limited in implementation.

[0063] like Figures 10 to 14 As shown, the blocking feature 26 has a first blocking portion 80, and preferably, also has a second blocking portion 82, and the second blocking portion 82 and the first blocking portion 80 are located at two ends of the blocking feature 26, for example, at two opposite ends. Here, the first blocking portion 80 and the second blocking portion 82 are respectively located at the rear end and the front end of the blocking feature 26 for example, but the implementation is not limited thereto.

[0064] Further, when the second rail 24 is at a predetermined position P (e.g., an extended position, but not limited thereto) relative to the first rail 22, the first stopper 80 of the blocking feature 26 and the first predetermined portion 72 of the first member 28 may block each other to prevent the second rail 24 from moving relative to the first rail 22 from the predetermined position P to a first direction D1; preferably, the second stopper 82 of the blocking feature 26 and the second predetermined portion 74 of the second member 32 may block each other to prevent the second rail 24 from moving relative to the first rail 22 from the predetermined position P to a second direction D2 opposite to the first direction D1. The first direction D1 may be, for example, an opening direction, and the second direction D2 may be, for example, a folding direction, but not limited thereto.

[0065] Preferably, when the second rail 24 is in the predetermined position P relative to the first rail 22, the first component 28 and the second component 32 are in the first state S1 and the first component 28 and the second component 32 are blocked by the first blocking portion 80 and the second blocking portion 82 of the blocking feature 26 through the first predetermined portion 72 and the second predetermined portion 74, respectively, to prevent the second rail 24 from moving relative to the first rail 22 from the predetermined position P to the first direction D1 or the second direction D2.

[0066] Furthermore, one of the first stop portion 80 of the blocking feature 26 and the first predetermined portion 72 of the first component 28 is a non-upright structure, so that when the first stop portion 80 of the blocking feature 26 and the first predetermined portion 72 of the first component 28 block each other, it can ensure that the second rail 24 cannot easily move from the predetermined position P to the first direction D1 relative to the first rail 22, or it can help to ensure the reliability of the first stop portion 80 of the blocking feature 26 and the first predetermined portion 72 of the first component 28 when blocking each other.

[0067] Preferably, the blocking feature 26 has a low section 84 and a high section 86, the first stopper 80 is located between the low section 84 and the high section 86, and the high section 86 has a first inclination angle K1 relative to the low section 84 (eg Fig.12 and Fig.13 As shown), the first stop portion 80 has the non-upright structure.

[0068] Similarly, one of the second stopper 82 of the blocking feature 26 and the second predetermined portion 74 of the second member 32 is another non-vertical structure, so that when the second stopper 82 of the blocking feature 26 and the second predetermined portion 74 of the second member 32 block each other, it can ensure that the second rail 24 cannot move from the predetermined position P to the second direction D2 relative to the first rail 22, or it can help the reliability when the second stopper 82 of the blocking feature 26 and the second predetermined portion 74 of the second member 32 block each other. In other words, the second rail 24 cannot return from the predetermined position P to the second direction D2 to the above-mentioned folded position R.

[0069] Preferably, the second stopper 82 is located between the low section 84 and the high section 86, and the high section 86 has a second inclination angle K2 relative to the low section 84 (eg, Fig.12 and Fig.13 As shown), the second stop portion 82 has the other non-upright structure.

[0070] Preferably, the second inclination angle K2 is substantially the same as the first inclination angle K1 (eg Fig.12 and Fig.13 shown).

[0071] Preferably, a first longitudinal length M1 of the high section 86 of the blocking feature 26 is substantially greater than a second longitudinal length M2 of the low section 84 (eg, Fig.12 and Fig.13 shown).

[0072] Preferably, the blocking feature 26 substantially protrudes laterally relative to the longitudinal wall 42 of the first rail 22, so that the high section 86 of the blocking feature 26 has a lateral height T relative to the low section 84 (eg, Fig.12 shown).

[0073] Preferably, the second level 76b of the step structure 76 of the first member 28 has a low point 88 and a high point 90, the first predetermined portion 72 is located between the low point 88 and the high point 90, and the high point 90 has a third inclination angle K3 relative to the low point 88, so that the first predetermined portion 72 has the non-vertical structure. Fig.14As shown, when an external force (or impact force) is applied to the second rail 24 at the predetermined position P in the first direction D1, the first predetermined portion 72 of the first member 28 will collide with the first stop portion 80 of the blocking feature 26. This collision may cause the first member 28 to slightly move or tilt in a lateral direction t. Therefore, in this embodiment, one of the first stop portion 80 of the blocking feature 26 and the first predetermined portion 72 of the first member 28 has the non-upright structure, for example, the first stop portion 80 of the blocking feature 26 has the non-upright structure, so that the high section of the first stop portion 80 of the blocking feature 26 86 has a first shoulder 96 relative to the lower section 84, and the first shoulder 96 can be used to prevent or block the first component 28 from moving in the lateral direction t, thereby preventing the first predetermined portion 72 and the first stop portion 80 from lateral separation from each other, so that when the first stop portion 80 of the blocking feature 26 and the first predetermined portion 72 of the first component 28 block each other, it can ensure that the second rail 24 is not easy to move from the predetermined position P to the first direction D1 relative to the first rail 22, or it can help the reliability of the first stop portion 80 of the blocking feature 26 and the first predetermined portion 72 of the first component 28 when blocking each other. Similarly, when another external force (or impact force) is applied to the second rail 24 at the predetermined position P in the second direction D2, the second predetermined portion 74 of the second member 32 will collide with the second stop portion 82 of the blocking feature 26. This collision may cause the second member 32 to move slightly or tilt in the lateral direction t. Since the second stop portion 82 of the blocking feature 26 and one of the second predetermined portion 74 of the second member 32 have another non-vertical structure, the high section 86 of the second stop portion 82 of the blocking feature 26 has a first vertical distance relative to the low section 84. The two shoulders 98 can be used to prevent or block the second component 32 from moving in the lateral direction t, avoiding the second predetermined portion 74 and the second stop portion 82 from lateral separation from each other, so that when the second stop portion 82 of the blocking feature 26 and the second predetermined portion 74 of the second component 32 block each other, it can ensure that the second rail 24 is not easy to move from the predetermined position P to the second direction D2 relative to the first rail 22, or it can help the reliability when the second stop portion 82 of the blocking feature 26 and the second predetermined portion 74 of the second component 32 block each other. For the sake of simplicity, it is not further described.

[0074] Preferably, the second layer 76b has a thickness between the low part 88 and the high part 90, and the thickness is smaller than the lateral height T (eg Fig.12 As shown in FIG. 1 ). Accordingly, the second level 76b (i.e., the first predetermined portion 72 of the first member 28) can correspond to the range of the lateral height T of the blocking feature 26, which helps to ensure the reliability of the mutual blocking between the first stop portion 80 of the blocking feature 26 and the first predetermined portion 72 of the first member 28, so as to ensure that the second rail 24 will not move in the first direction D1 when it is in the predetermined position P relative to the first rail 22.

[0075] Similarly, the second level 78b of the other step structure 78 of the second member 32 has a low point 92 and a high point 94, the second predetermined portion 74 is located between the low point 92 and the high point 94, and the high point 94 has a fourth inclination angle K4 relative to the low point 92, so that the second predetermined portion 74 has the other non-vertical structure. The second level 78b has a thickness between the low point 92 and the high point 94, and the thickness is less than the lateral height T (such as Fig.12 As shown in FIG. 1 ). Accordingly, the second level 78b (i.e., the second predetermined portion 74 of the second member 32) can correspond to the range of the lateral height T of the blocking feature 26, which helps to ensure the reliability of the second stop portion 82 of the blocking feature 26 and the second predetermined portion 74 of the second member 32 blocking each other, thereby ensuring that the second rail 24 will not move in the second direction D2 when it is at the predetermined position P relative to the first rail 22.

[0076] It is worth mentioning that once the first member 28 is operated to be in the second state S2 (for example Fig. 9 The first member 28 is shown in the second state S2), the first predetermined portion 72 of the first member 28 is no longer blocked by the first stop portion 80 of the blocking feature 26, so as to allow the second rail 24 to move from the predetermined position P to the first direction D1 relative to the first rail 22 and be removed or disengaged from the channel of the first rail 22; or, once the second member 32 is operated to be in the second state S2 (for example Figure 7 The second member 32 is shown in the second state S2, and the second predetermined portion 74 of the second member 32 is no longer blocked by the second stop portion 82 of the blocking feature 26, so as to allow the second rail 24 to move from the predetermined position P to the second direction D2 relative to the first rail 22 to the above-mentioned retracted position R (such as Figure 1 shown).

[0077] According to the above description, it can be seen that the improved effects and advantages of the present invention are:

[0078] a. The blocking portion (first blocking portion 80 or second blocking portion 82) of the blocking feature 26 and the predetermined portion (first predetermined portion 72 or second predetermined portion 74) of the component (first component 28 or second component 32) are a non-vertical structure (for example, the blocking portion of the blocking feature 26 and the predetermined portion of the component have an inclined angle), so that when the blocking portion of the blocking feature 26 and the predetermined portion of the component in the first state S1 block each other, it can ensure that the second rail 24 cannot move away from the predetermined position P in one direction (first direction D1 or second direction D2) relative to the first rail 22, thereby improving the reliability or safety of the slide rail assembly 20 in use.

[0079] b. When the second rail 24 is at a predetermined position P relative to the first rail 22, the blocking portion (the first blocking portion 80 or the second blocking portion 82) of the blocking feature 26 and the predetermined portion of the component (the first component 28 or the second component 32) block each other to prevent the second rail 24 from moving in a direction from the predetermined position P relative to the first rail 22; wherein the blocking feature 26 substantially protrudes laterally relative to the longitudinal wall 42 of the first rail 22, so that the high section 86 of the blocking feature 26 has a horizontal height T relative to the low section 84; wherein a step structure is provided between the first side L1 and the second side L2 of the component, and the step structure has a first level and a second level connecting the first level; the predetermined portion (the first predetermined portion 72 or the second predetermined portion 74) of the component is located at the second level; wherein a thickness between the low part 88 and the high part 90 of the second level is less than the horizontal height T.

Therefore, any changes and modifications to the above embodiments within the spirit of the present invention will fall within the scope of the claims of this application.
