Abstract

The invention relates to a slide rail assembly, which comprises a supporting mechanism and a slide rail. The slide rail and the supporting mechanism are movably mounted with each other. The supporting mechanism and the sliding rail have the structure and the characteristics that can be matched with each other, so that the sliding rail can be located at a first extending position in a first direction relative to the supporting mechanism, or the sliding rail can be located at a second extending position in a second direction relative to the supporting mechanism.

Description

Sliding rail assembly

Technical Field

The present invention relates to a sliding rail mechanism, and more particularly, to a sliding rail assembly with a sliding rail capable of being opened in two directions.

Background

The slide rail assembly is quite versatile. For example, the slide rail assembly can be used to carry a carrying object, so that the carrying object can be opened or closed relative to a fixed object (e.g., a cabinet or a rack). For example, U.S. patent publication No. US9,480,183B2 discloses a slide rail assembly 10 including a first rail 44, a second rail 46, and a latch 48. When the second rail 46 moves to an extended position in a direction relative to the first rail 44, the second rail 46 can be stopped at the extended position by the contact portion 66 of the latch 48 abutting against the stopper 30 of the arm 26, so that the second rail 46 and a load (e.g., a chassis) carried by the second rail 46 can be prevented from being separated from the first rail 44.

However, with the different demands of the market for the sliding track assembly, how to develop a different sliding track product becomes an issue worth discussing.

Detailed Description

As shown in fig. 1 and fig. 2, the slide rail assembly 20 of the embodiment of the invention includes a supporting mechanism 22 and a slide rail 24.

The support mechanism 22 includes a first structure 26 (see fig. 3), a second structure 28 (see fig. 4), and a path 30 disposed between the first structure 26 and the second structure 28. Preferably, the supporting mechanism 22 includes a first end 22a and a second end 22 b. The first end 22a and the second end 22b are, for example, a front portion and a rear portion, but the implementation is not limited thereto. Further, the second end 22b is far from the first end 22 a. The first structure 26 is disposed adjacent the first end 22a, and the second structure 28 is disposed adjacent the second end 22 b. Preferably, the support mechanism 22 includes an upper wall 32, a lower wall 34 and a longitudinal wall 36 connected between the upper wall 32 and the lower wall 34. The upper wall 32, the lower wall 34 and the longitudinal wall 36 together define a channel that can serve as the path 30.

The slide rail 24 is displaceable relative to the support mechanism 22 via the path 30; alternatively, the slide rail 24 and the support mechanism 22 may be movably mounted relative to each other through the channel. Further, the slide rail 24 has a first end 24a and a second end 24b, and a first feature 38a and a second feature 38b are disposed between the first end 24a and the second end 24 b. Preferably, the track 24 comprises a first wall 35, a second wall 37 and a side wall 39 connected between the first wall 35 and the second wall 37. The first wall 35 and the second wall 37 of the slide rail 24 can be supported by the upper wall 32 and the lower wall 34 of the supporting mechanism 22, respectively, and the position of the side wall 39 of the slide rail 24 corresponds to the position of the longitudinal wall 36 of the supporting mechanism 22. Preferably, the slide assembly 20 further includes a working member 40 mounted to the slide 24. Here, the working member 40 is exemplified to be operatively mounted on the side wall 39 of the slide rail 24, with the working member 40 facing the longitudinal wall 36 of the support mechanism 22. Wherein the working member 40 is provided with the first feature 38a and the second feature 38 b. Preferably, the working member 40 includes a first resilient portion 42 and a second resilient portion 44, and the first feature 38a and the second feature 38b are disposed between the first resilient portion 42 and the second resilient portion 44. Preferably, a space 46 is formed between the first feature 38a and the second feature 38b, and the first feature 38a and the second feature 38b are walls on both sides of the space 46. Preferably, the first elastic portion 42 and the second elastic portion 44 each have a connecting section 48 and an elastic section 50. Wherein the connecting section 48 is mounted to the slide rail 24. For example, the connecting section 48 and the slide rail 24 are mounted to each other by a connector 52 and a hole 54 (e.g., a longitudinal hole), preferably, the size of the hole 54 is slightly larger than the connector 52, so that the working member 40 can move slightly relative to the slide rail 24 when subjected to an external force; alternatively, the working member 40 is fixed to the slide rail 24 by the connecting section 48, for example, by riveting or welding. Thus, the manner in which the workpiece 40 is mounted on the slide rail 24 is not limited in implementation. On the other hand, the elastic section 50 extends from the connecting section 48 and tilts a predetermined height relative to the connecting section 48. The first feature 38a and the second feature 38b are respectively disposed on the elastic section 50 of the second elastic portion 44 and the elastic section 50 of the first elastic portion 42. Wherein, the two elastic sections 50 have a guiding surface 51 for cooperating with the first structure 26 and the second structure 28, respectively. Preferably, the guiding surface 51 is, for example, a slope or a cambered surface.

As shown in fig. 5, the first structure 26 or the second structure 28 of the supporting mechanism 22 is a protrusion, and here, the first structure 26 and the second structure 28 are both protrusions. Preferably, the first structure 26 and the second structure 28 each have a stop portion 56 and a guide portion 58. The stop portion 56 and the guide portion 58 are opposite sides. Preferably, the guide portion 58 is a ramp or a curved surface.

Further, the slide rail 24 can be located at a predetermined position, such as a retracted position, relative to the supporting mechanism 22. Wherein, at the predetermined position, the slide rail 24 is located between the first structure 26 and the second structure 28. In addition, the slide rail 24 can be displaced from the predetermined position to a first direction D1 or a second direction D2 relative to the supporting mechanism 22. Wherein the first direction D1 is opposite to the second direction D2. Wherein the workpiece 40 is in a first state S1 (e.g., not yet operated).

As shown in fig. 6, when the slide rail 24 is displaced a distance along the path 30 from the predetermined position to the first direction D1, the guide surface 51 of the first resilient portion 42 of the working member 40 contacts the first structure 26 to generate a force applied to the working member 40, so that the working member 40 is no longer in the first state S1, and at this time, the first resilient portion 42 (and the second resilient portion 44) are in a state of accumulating a resilient force.

As shown in fig. 7, when the slide rail 24 continues to move in the first direction D1 to a first extended position E1, the first end 24a of the slide rail 24 extends beyond the first structure 26 (or beyond the first end 22a), and the first feature 38a is blocked by the first structure 26 to prevent the slide rail 24 from moving in the first direction D1 from the first extended position E1. For example, when the slide rail 24 is at the first extended position E1, the position of the first structure 26 corresponds to the space 46, so that the first elastic portion 42 (and the second elastic portion 44) releases the elastic force to restore the working member 40 to the first state S1, and the first feature 38a and the second feature 38b are respectively located at two sides of the first structure 26. Wherein, the stop portion 56 of the first structure 26 can be used to stop the first feature 38a to prevent the slide rail 24 from being displaced from the first extended position E1 to the first direction D1; alternatively, the guiding portion 58 of the first structure 26 can be used to block the second feature 38b to prevent the sliding rail 24 from moving from the first extended position E1 to the second direction D2, and it should be noted that, since the guiding portion 58 of the first structure 26 is a slope or a curved surface, a user slightly applies a force to the sliding rail 24 in the second direction D2 to slide the second feature 38b in the second direction D2 over the guiding portion 58 of the first structure 26, so that the sliding rail 24 can be folded from the first extended position E1 to the second direction D2.

As shown in fig. 7, 8 and 9, when the slide rail 24 is in the first extended position E1 (shown in fig. 7) relative to the support mechanism 22, the user can operate the working member 40 to change from the first state S1 to a second state S2 (e.g., the operated state, shown in fig. 8). When the working member 40 is in the second state S2, the stop portion 56 of the first structure 26 of the supporting mechanism 22 no longer stops the first feature 38a of the working member 40, so that the slide rail 24 can be displaced in the first direction D1 and detached from the supporting mechanism 22 (as shown in fig. 9). On the other hand, when the slide rail 24 is to be reassembled to the supporting mechanism 22, the first end 24a or the second end 24b can be inserted into the first end 22a or the second end 22b of the supporting mechanism 22, which is not limited to the implementation.

Specifically, when the slide rail 24 is in the first extended position E1 (as shown in fig. 7) and the elastic section (e.g., the elastic section 50 of the first elastic portion 42) is pressed by a force F (as shown in fig. 8), the first feature 38a and the second feature 38b are no longer located on both sides of the first structure 26, so that the slide rail 24 can be detached from the supporting mechanism 22 from the first extended position E1 in the first direction D1 (as shown in fig. 9), or the slide rail 24 can be folded relative to the supporting mechanism 22 from the first extended position E1 in the second direction D2.

As shown in fig. 10, when the slide rail 24 is detached from the supporting mechanism 22 and the supporting mechanism 22 is to be installed again, the slide rail 24 can be installed again to the supporting mechanism 22 in the second direction D2, wherein, by the guiding portion 58 of the first structure 26 being a slope or a curved surface, a user slightly applies a force to the slide rail 24 in the second direction D2 to slide the second feature 38b in the second direction D2 over the guiding portion 58 of the first structure 26, so that the slide rail 24 can be folded from the first extended position E1 (this portion can be referred to as fig. 7) to the second direction D2.

As shown in fig. 5 and 11, when the slide rail 24 is moved from the predetermined position (shown in fig. 5) to a second extended position E2 (shown in fig. 11) along the path in the second direction D2, the second end 24b of the slide rail 24 exceeds the second structure 28 (or exceeds the second end 22b), and the second feature 38b is blocked by the second structure 28 to prevent the slide rail 24 from being moved from the second extended position E2 to the second direction D2.

For example, when the slide rail 24 is at the second extended position E2, the position of the second structure 28 corresponds to the space 46, and the working member 40 is in the first state S1 by the elastic force of the first elastic portion 42 (and the second elastic portion 44), and the first feature 38a and the second feature 38b are respectively located at two sides of the second structure 28. Wherein the stop portion 56 of the second structure 28 can be used to stop the second feature 38b of the working member 40, so as to prevent the slide rail 24 from being displaced from the second extended position E2 to the second direction D2; alternatively, the guiding portion 58 of the second structure 28 can be used to block the first feature 38a to prevent the sliding rail 24 from moving from the second extended position E2 to the first direction D1, and it should be noted that, since the guiding portion 58 of the second structure 28 is a slope or a curved surface, a user slightly applies a force to the sliding rail 24 in the first direction D1 to slide the first feature 38a to the first direction D1 to pass over the guiding portion 58 of the second structure 28, so that the sliding rail 24 can be folded from the second extended position E2 to the first direction D1.

As shown in fig. 11 and 12, when the slide rail 24 is at the second extended position E2 and the elastic section (e.g., the elastic section 50 of the second elastic portion 44) is pressed to convert the working member 40 from the first state S1 to the second state S2, the first feature 38a and the second feature 38b are no longer located at two sides of the second structure 28 (i.e., the second structure 28 no longer blocks the second feature 38b and the first feature 38a), so that the slide rail 24 can be detached from the support mechanism 22 from the second extended position E2 in the second direction D2 (as shown in fig. 12), or the slide rail 24 can be folded relative to the support mechanism 22 from the second extended position E2 in the first direction D1. Similarly, when the slide rail 24 is to be reassembled to the supporting mechanism 22, the first end 24a or the second end 24b can be inserted into the first end 22a or the second end 22b of the supporting mechanism 22, which is not limited to the above embodiments.

As shown in fig. 13 and 14, in one embodiment, the support mechanism 22 includes a first bracket 60 and a second bracket 62. The first bracket 60 is disposed at one end of a support rail 64, wherein the first bracket 60 comprises a longitudinal support wall 66 and at least one first mounting member 68 adjacent to the longitudinal support wall 66; on the other hand, the second bracket 62 comprises an extension rail 70 and at least one second mounting member 72 adjacent to the extension rail 70, wherein the extension rail 70 is movably mounted in a support channel 74 of the support rail 64, such that the first bracket 60 and the second bracket 62 are telescopically movable relative to each other, and the at least one second mounting member 72 can be located near the other end of the support rail 64 by the extension rail 70 being displaced relative to the support rail 64. Wherein one of the first bracket 60 and the second bracket 62 has the path 30. Here, it is exemplified that the longitudinal support wall 66 of the first bracket 60 and the extension rail 70 of the second bracket 62 have a first path 30a and a second path 30b communicating with each other, respectively. Further, the slide rail 24 can be displaced relative to the support mechanism 22 through the first path 30a and the second path 30 b. Wherein the first structure 26 is located on the longitudinal support wall 66 of the first bracket 60, and the second structure 28 is located on the extension rail 70 of the second bracket 62. When the slide rail 24 is in the predetermined position (e.g., the retracted position), the slide rail 24 is located between the first structure 26 and the second structure 28. For simplicity, the working member 40 is mounted on the slide rail 24, and details about the matching function relationship between the working member 40 and the first and

second structures

26 and 28 are not repeated.

Preferably, the support rail 64 and the extension rail 70 have a first stop feature 76 and a second stop feature 78, respectively. For example, one of the first and second stop features 76, 78 is an elastic arm, and the other of the first and second stop features 76, 78 is an aperture wall. The first stop feature 76 and the second stop feature 78 can abut against each other. It is exemplified herein that the first stop feature 76 is a resilient arm and the second stop feature 78 is an aperture wall.

As shown in fig. 14, the first bracket 60 and the second bracket 62 are mounted to a first mast 80 and a second mast 82 of a rack (rack) by at least one first mounting member 68 and at least one second mounting member 72, respectively. The first bracket 60 and the second bracket 62 are adjusted relative to each other to a first length L1 for the rack of a first depth. Wherein the first stop feature 76 (shown in fig. 16) and the second stop feature 78 (shown in fig. 15) are a predetermined distance from each other. On the other hand, the slide rail 24 can be used to carry a carrier 84, and the carrier 84 is, for example, an electronic device or a drawer. The slide rail 24 can be displaced and detached in the first direction D1 relative to the supporting mechanism 22, or the slide rail 24 can be displaced and detached in the second direction D2 relative to the supporting mechanism 22, and for the principle of detaching the slide rail 24 from the supporting mechanism 22, reference may be made to fig. 9 and 12 and the above description, which are not repeated herein for brevity.

As shown in fig. 17, the first bracket 60 and the second bracket 62 are adjusted relative to each other to a second length L2 greater than the first length L1 for the second depth of the rack. Wherein the first and second stop features 76, 78 abut against each other (as shown in fig. 18) to have a stop effect.

From the above description, it can be seen that the enhanced efficacy and advantages of the present invention are:

(1) the slide rail 24 can be displaced and detached in a first direction D1 relative to the support mechanism 22, and the slide rail 24 can also be displaced and detached in a second direction D2 relative to the support mechanism 22, which facilitates the convenience and versatility of the maintenance operation of the slide rail assembly 20. Alternatively, when the slide rail 24 carries the carrier 84, the carrier 84 can be detached from the support mechanism 22 from both directions by the slide rail 24, which facilitates the maintenance work of the equipment.

(2) The support mechanism 22 can be a slide, a bracket, or a combination of a slide and a bracket for supporting the slide 24, and the slide 24 can be opened from a predetermined position (e.g., a retracted position) to two directions relative to the support mechanism 22 through a path 30.

(3) Either end of the slide rail 24 can be inserted into the support mechanism 22, which provides more convenient and versatile installation requirements for users.

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.

when the slide rail is at the first extension position and the workpiece is in the first state, the position of the first structure corresponds to the space, and the first feature and the second feature are respectively positioned at two sides of the first structure; when the slide rail is at the second extending position and the workpiece is in the first state, the position of the second structure corresponds to the space, and the first feature and the second feature are respectively positioned at two sides of the second structure;

when the slide rail is located at the first extension position and the elastic section is pressed to be converted from the first state to the second state, the first feature and the second feature are no longer located at two sides of the first structure, so that the slide rail can be detached from the support mechanism from the first extension position in the first direction, or the slide rail can be folded relative to the support mechanism from the first extension position in the second direction; when the slide rail is located at the second extending position and the elastic section is pressed to be converted from the first state to the second state, the first feature and the second feature are no longer located at two sides of the second structure, so that the slide rail can be detached from the support mechanism from the second extending position in the second direction, or the slide rail can be folded relative to the support mechanism from the second extending position in the first direction.
