Detailed Description
As shown in fig. 1 and 2, a slide rail assembly 20 according to an embodiment of the present invention includes a first rail 22, a bracket, a second rail 26, and a locking device 28. The bracket is, for example, a front bracket 24, but is not limited in implementation. Preferably, another bracket is included, such as a rear bracket 30.
The first rail 22 has a first end and a second end far from the first end, such as a front end and a rear end. The first rail 22 includes a plurality of walls that collectively define a channel 32 for the second rail 26 to be movably mounted. A first wall 34a, a second wall 34b and a longitudinal wall 36 are disposed at a predetermined portion of the first rail 22 and connected between the first wall 34a and the second wall 34 b. The first wall 34a, the second wall 34b and the longitudinal wall 36 together define the channel 32.
The front bracket 24 is disposed on the first rail 22, and the front bracket 24 has a locking portion 38. Preferably, the front bracket 24 is disposed adjacent to the front end of the first rail 22. On the other hand, the rear bracket 30 is disposed adjacent to the rear end portion of the first rail 22. Preferably, one of the front bracket 24 and the rear bracket 30 is longitudinally adjustable in position relative to the first rail 22. Preferably, the front bracket 24 includes a side plate 44 and an end plate 46 adjacent to the side plate 44, for example, the end plate 46 is substantially perpendicular to the side plate 44, wherein two mounting members 48 are disposed on the end plate 46, and the lock portion 38 is located between the two mounting members 48.
The second rail 26 is longitudinally displaceable relative to the first rail 22. The second rail 26 has a first end and a second end away from the first end, such as a front end 26a and a rear end 26 b. It should be noted that in this embodiment, the X-axis direction is the longitudinal direction (or the length direction or the 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).
The lock device 28 is disposed adjacent to the second rail 26, and the lock device 28 includes a lock seat 40 and a lock element 42.
Preferably, the lock device 28 is disposed at the front end 26a of the second rail 26.
Preferably, a fixed base 50 is connected to the inner side of the front end 26a adjacent to the second rail 26, and when the second rail 26 is in a retracted position, the fixed base 50 is positioned beyond the end plate 46 of the front bracket 24 (as shown in fig. 1); the fixed base 50 has a hole H (it can also be considered that the second rail 26 has the hole H), and the lock base 40 has a connecting section 52 passing through the hole H of the fixed base 50, so that the lock base 40 is connected (e.g., movably connected) to the fixed base 50. On the other hand, the locking member 42 is disposed on the locking seat 40.
As shown in fig. 3-5, the lock seat 40 is operatively disposed in one of an open state K1 (shown in fig. 3) and a closed state K2 (shown in fig. 5) relative to the second rail 26. Here, the lock seat 40 can rotate from the open state K1 to the closed state K2 relative to the second rail 26; alternatively, the lock seat 40 can rotate relative to the second rail 26 from the closed state K2 to the open state K1.
When the lock holder 40 is in the open state K1, the lock 42 is away from (or misaligned with) the lock 38 of the front bracket 24 (as shown in fig. 3); when the lock holder 40 is in the closed state K2, the lock 42 corresponds to (or aligns with) the lock portion 38 of the front bracket 24 (as shown in fig. 5).
Preferably, the locking portion 38 is a threaded hole, the locking member 42 includes an operating portion 54 and a threaded portion 56 connected to the operating portion 54, and the threaded portion 56 and the locking portion 38 are matched with each other.
Further, when the second rail 26 is located at a predetermined position, such as the retracted position P1, relative to the first rail 22, the lock seat 40 can be operated from the open state K1 (shown in fig. 3) to rotate in a predetermined direction R (shown in fig. 4) to the closed state K2, such that the lock 42 can be locked into the lock portion 38 of the front bracket 24 by the threaded portion 56, and the second rail 26 cannot be displaced from the retracted position P1 (shown in fig. 5) relative to the first rail 22. That is, when the locking member 42 is locked into the locking portion 38 of the front bracket 24, the second rail 26 is fixed at the retracted position P1. It should be noted that when the lock seat 40 is in the closed state K2 and the locking element 42 is corresponding to (or aligned with) the lock portion 38 of the front bracket 24, a user can apply a force to the operation portion 54 by hand or a tool (e.g., a screwdriver), so that the locking element 42 is rotated to lock the threaded portion 56 into the lock portion 38 of the front bracket 24 (as shown in fig. 5).
Preferably, the lock base 40 has a bent portion 58, and the bent portion 58 of the lock base 40 is adjacent to the side 60 of the end plate 46 of the front bracket 24 (as shown in fig. 5) when the lock base 40 is in the closed state K2.
Preferably, the slide rail assembly 20 further includes a fastener 62 movably mounted to the front bracket 24 (as shown in fig. 3). For example, the fastener 62 is pivotally connected to the front bracket 24 by a shaft 64, so that the fastener 62 can move between a locked position C (shown in fig. 3) or an unlocked position (not shown). Wherein, when the fastening member 62 is at the locking position C, a fastening portion 65 of the fastening member 62 is adjacent to the front of the end plate 46 of the front bracket 24. Preferably, the fastener 62 can be maintained at the locking position C by the elastic force of an elastic portion, and the fastener 62 is within the technical scope that can be understood by those skilled in the art, and therefore, for the sake of brevity, will not be described herein again.
As shown in fig. 6 and 7, two slide rail assemblies 20 are mounted to a frame. Specifically, the rack includes at least one pair of columns, such as a pair of front columns 66a and a pair of rear columns 66b, each front column 66a and each rear column 66b is mounted with a corresponding slide assembly 20, wherein the first rail 22 of the slide assembly 20 is mounted to the front column 66a and the rear column 66b through the front bracket 24 and the rear bracket 30, respectively, and the second rail 26 can carry a carrying object 68, such as an electronic device. The second rail 26 is in the retracted position P1 relative to the first rail 22. The principle of the front bracket 24 being mounted to the front column 66a and the principle of the rear bracket 30 being mounted to the rear column 66b are substantially the same, for example, the front column 66a includes a plurality of mounting holes (e.g., a first mounting hole 70a, a second mounting hole 70b and a third mounting hole 70C are located between the first mounting hole 70a and the second mounting hole 70 b), the front bracket 24 is mountable to the first mounting hole 70a and the second mounting hole 70b of the front column 66a by the two mounting members 48, and the fastener 62 is in the locking position C and can lock the front of the front column 66a by the fastening part 65 (as shown in fig. 7). The lock seat 40 is operatively in the open state K1 relative to the second rail 26, and at this time, the second rail 26 is displaceable relative to the first rail 22 from the retracted position P1 to a first direction D1.
As shown in fig. 8, when the second rail 26 is at the retracted position P1 relative to the first rail 22, the lock seat 40 is operatively in the closed state K2, so that the threaded portion 56 of the locking member 42 can be locked into the lock portion 38 of the front bracket 24, and the carrying object 68 is held in the rack and cannot be arbitrarily moved out of the rack. Further, once the lock seat 40 is operatively in the closed state K2 relative to the second rail 26, such that the threaded portion 56 of the locking element 42 is locked into the lock portion 38 of the front bracket 24, the second rail 26 is not displaceable relative to the first rail 22 from the retracted position P1 in the first direction D1. That is, the carrier 68 is fixed at the retracted position P1.
As shown in fig. 9, once the lock seat 40 is no longer in the closed state K2 (e.g., in the open state K1) relative to the second rail 26, the second rail 26 can be displaced from the retracted position P1 to the first direction D1 relative to the first rail 22 to an extended position P2 and outside the rack. It should be noted that the second rail 26 is movable relative to the first rail 22 from the extended position P2 to a second direction D2 opposite to the first direction D1 to the retracted position P1 to be retracted into the housing.
As shown in fig. 10 and 11, the fastener 62 is omitted, wherein the fixing base 50 has a thickness T (as shown in fig. 10), and the connecting section 52 of the lock seat 40 defines a connecting space S having a boundary, and the width of the connecting space S is greater than the thickness T, so that the lock seat 40 can be laterally adjusted relative to the fixing base 50 of the second rail 26. For example, the lock base 40 can be adjusted and displaced from a first lateral position Y1 (shown in fig. 10) to a second lateral position Y2 (shown in fig. 11).
Preferably, when the lock seat 40 is located at the second transverse position Y2 and in the closed state K2, such that the lock member 42 is locked into the lock portion 38 of the front bracket 24 (as shown in fig. 11), one side of the lock seat 40 and one side of the second rail 26 are substantially located on the same longitudinal plane L. This is advantageous, for example, when the second rail 26 is in the retracted position P1 relative to the first rail 22, so as to ensure that the lock seat 40 does not block the front of the carrier 68, for example, the lock seat 40 does not block the electrical connectors, cables, warning lights or related signs of the carrier 68, and thus, the maintenance of the carrier 68 or the slide rails by field personnel is facilitated. Alternatively, the second transverse position Y2 is located by the lock seat 40 to facilitate the alignment or locking of the lock 42 to the lock portion 38 of the front bracket 24. Preferably, the bent portion 58 of the lock seat 40 can be correspondingly abutted against the front surface of the column (e.g., the front column 66a) (as shown in fig. 11), so as to improve the fastening effect of the front bracket 24 to the column.
Fig. 12 to 14 show an arrangement of another embodiment of the present invention, which is substantially the same as the previous embodiment, mainly different in that the locking part 202 of the front bracket 200 is disposed on the buckling part of the buckling member 204, the locking device 206 is disposed on the second rail 208, and the lock seat 210 is in the open state K1, and the locking element 212 is far away from (not corresponding to) the locking part 202. On the other hand, the locking part 202 is shown in front of the end plate 201 or the column 214 when the front bracket 200 is mounted on the column 214. In contrast to the previous embodiments, for example, when the front bracket 24 shown in fig. 7 is mounted on the front pillar 66a, the lock portion 38 is located at a position behind the front pillar 66a, and therefore, the lock 42 of the previous embodiments is located slightly farther from the position of the lock portion 38. In the present embodiment, the position of the screw portion of the locking member 212 with respect to the lock portion 202 can be shortened by moving the lock portion 202 forward to be located in front of the end plate 201 or the column 214.
If the locking element 212 of the locking device 206 is to be locked, the locking seat 210 may be manually displaced, for example, by pushing the locking seat 210 with an external force F (as shown in fig. 14), so that the locking seat 210 is laterally displaced from the open state K1 to the closed state K2, and the threaded portion of the locking element 212 corresponds to the locking portion 202 (as shown in fig. 15 and 16), so as to lock the locking element 212 to the locking portion 202 (as shown in fig. 17). Preferably, the connecting section 211 of the lock base 210 passes through the hole H '(as shown in fig. 15) of the second rail 208, and the lock base 210 is provided with a feature 216 (e.g., a bent portion), when the locking element 212 is locked to or corresponds to (not locked to) the position where the locking element 202 is fixed, the feature 216 of the lock base 210 abuts against the front end 208a of the second rail 208, and the connecting section 211 of the lock base 210 abuts against the inner wall of the hole H' of the second rail 208, thereby forming a front-back blocking relationship; alternatively, even though the lock holder 210 and the second rail 208 are not abutted, the gap between the lock holder 210 and the front end 208a of the second rail 208 can be shortened by the feature 216, so that when the second rail 208 is extended and displaced relative to the front bracket 200, the problem that the lock holder 210 is displaced forward and backward relative to the second rail 208 due to the gap (or longitudinal gap) between the lock holder 210 and the second rail 208 is not caused.
As shown in fig. 18 and 19, the configuration of the further embodiment of the present invention is substantially the same as the previous embodiment, and the main difference lies in the structural configuration relationship between the second rail and the lock device. Specifically, the second rail 300 includes a first wall 302a, a second wall 302b and a longitudinal wall 304 connected between the first wall 302a and the second wall 302b of the second rail 300, the longitudinal wall 304 of the second rail 300 having a first side M1 and a second side M2 opposite in position. On the other hand, the lock seat 306 of the lock device is movably mounted on the second rail 300, and the lock 308 is disposed on the lock seat 306.
Preferably, the longitudinal wall 304 of the second rail 300 has a predetermined space 309 communicating the first side M1 and the second side M2, and the lock seat 306 can be laterally displaced relative to the longitudinal wall 304 of the second rail 300 through the predetermined space 309, wherein the predetermined space 309 is a hole, but is not limited in implementation.
Preferably, the slide rail assembly further comprises an auxiliary member 310 movably mounted on the first side M1 of the longitudinal wall 304 of the second rail 300, the auxiliary member 310 having a supporting portion 312 adjacent to the predetermined space 309, and the supporting portion 312 of the auxiliary member 310 having a thickness T'; on the other hand, the lock base 306 has a connecting section 314, and the connecting section 314 of the lock base 306 defines a connecting space S ' for accommodating the supporting portion 312 of the auxiliary member 310, wherein the width of the connecting space S ' is greater than the thickness T ', so that the lock base 306 can be laterally adjusted with respect to the auxiliary member 310 (or the longitudinal wall 304 of the second rail 300).
Preferably, the connecting section 314 of the lock housing 306 is located corresponding to the predetermined space 309 of the longitudinal wall 304 of the second rail 300.
Preferably, the auxiliary 310 and the longitudinal wall 304 of the second rail 300 are longitudinally movable within a limited range relative to each other by the cooperation of at least a first connection feature 316 and a second connection feature 318. Here, the auxiliary member 310 has a first connecting feature 316, and the first connecting feature 316 is, for example, a longitudinal feature (e.g., a hole or a slot) with a boundary; on the other hand, a second connecting feature 318, such as a projection (e.g., a pin, a rivet, or a bolt) may be disposed through a portion of the longitudinal feature and connected to the first side M1 of the longitudinal wall 304 of the second rail 300 for mounting the auxiliary 310 to the second rail 300.
As shown in fig. 20 and 21, the lock base 306 can be located at a second transverse position Y2' relative to the longitudinal wall 304 of the second rail 300, and the lock base 306 can be located at a closed state relative to the second rail 300; alternatively, the auxiliary member 310 can be located at a first longitudinal position L1 (shown in fig. 20) relative to the longitudinal wall 304 of the second rail 300. Here, when the lock holder 306 is located at the second transverse position Y2' and in the closed state, the side portion 320 of the lock holder 306 does not exceed the second side M2 of the longitudinal wall 304 of the second rail 300 (as shown in fig. 21), and here, the side portion 320 of the connecting section 314 of the lock holder 306 corresponds to the predetermined space 309 of the longitudinal wall 304 of the second rail 300, and the side portion 320 of the connecting section 314 of the lock holder 306 does not exceed the second side M2 of the longitudinal wall 304 of the second rail 300, which is taken as an example and not a limitation (as shown in fig. 21).
Preferably, when the lock base 306 is located at the second transverse position Y2', a bending feature 322 of the connecting section 314 of the lock base 306 and a wall 324 of the predetermined space 309 of the longitudinal wall 304 of the second rail 300 are blocked to keep the lock base 306 in the closed state (as shown in fig. 20), so that the lock base 306 cannot move from the closed state to the open state.
As shown in fig. 22 and 23, when an external force F ' is applied to the lock seat 306, the lock seat 306 can move transversely relative to the longitudinal wall 304 of the second rail 300 from the second transverse position Y2 ' to the first transverse position Y1 '. Further, the lock seat 306 can be shifted from the second transverse position Y2 'to the first transverse position Y1' through the predetermined space 309. When the lock base 306 is located at the first transverse position Y1', the side portion 320 of the lock base 306 is beyond the second side M2 of the longitudinal wall 304 of the second rail 300, and at this time, the bending feature 322 of the connecting section 314 of the lock base 306 is no longer blocked from the edge wall 324 of the predetermined space 309 of the longitudinal wall 304 of the second rail 300 (as shown in fig. 23).
As shown in fig. 24 and 25, when the lock base 306 is located at the first transverse position Y1 ', the lock base 306 can be operated to rotate in a predetermined direction R' from the closed state to the open state (as shown in fig. 25) because the bending feature 322 of the connecting section 314 of the lock base 306 is no longer blocked by the edge wall 324 of the predetermined space 309 of the longitudinal wall 304 of the second rail 300. Further, when the lock housing 306 moves from the closed state to the open state, a portion 317 of the connecting section 314 of the lock housing 306 (e.g., a wall surface in the connecting space S' of the connecting section 314) can drive the auxiliary element 310 from the first longitudinal position L1 (shown in fig. 24) to a second longitudinal position L2 (shown in fig. 25).
As shown in fig. 26, the second side M2 of the second rail 300 can be mounted with a load-bearing object 328. When the second rail 300 is located at a predetermined position, such as a retracted position, relative to the first rail 326, the lock housing 306 is operatively located at the second transverse position Y2' and is in the closed state, wherein, since the side portion 320 of the lock housing 306 does not exceed the second side M2 of the longitudinal wall 304 of the second rail 300, the side portion 320 of the lock housing 306 does not interfere with the side surface 330 of the carrier 328 carried by the second rail 300, which is advantageous, for example, in that the side surface 330 of the carrier 328 can be flush with the second side M2 of the longitudinal wall 304 of the second rail 300 as much as possible to prevent a transverse gap from existing between the side surface 330 of the carrier 328 and the second side M2 of the longitudinal wall 304 of the second rail 300. Therefore, when the carrier 328 is to be mounted to the second rail 300, a fastener (e.g., a screw or bolt) is advantageously used to lock the side 330 of the carrier 328 to the second side M2 of the longitudinal wall 304 of the second rail 300.
Further, when the second rail 300 is located at the retracted position relative to the first rail 326 and the lock seat 306 is in the closed state, the (threaded portion of the) locking element 308 can be corresponding to and locked in the lock portion of the front bracket 332 (as this portion is disclosed in the first two embodiments, for brevity, the detailed description is omitted here). To pull the carrier 328 from the front pillar 340, the carrier 328 can be pulled by simply releasing the locking member 308 from the locking portion of the front bracket 332.
Preferably, the fastener 334 of the slide assembly is movably mounted on the front bracket 332, and when the fastener 334 is in the locking position, the fastening portion 336 of the fastener 334 is adjacent to the end plate 338 of the front bracket 332 or the front of the front pillar 340, and can be used to lock the front pillar 340.
From the above description, it can be seen that the enhanced efficacy and advantages of the present invention are:
a. when the second rail 26 is at the retracted position P1 relative to the first rail 22, the lock seat 40 is in the closed state K2, so that the lock 42 can be locked in the lock 38 of the front bracket 24, and the second rail 26 cannot move from the retracted position P1 to the extended position P2 relative to the first rail 22. With this arrangement, when the slide assembly 20 is applied to a rack, the second rail 26 cannot be displaced from the retracted position P1 to the extended position P2 relative to the first rail 22, so that the carrier 68 can be kept in the rack and cannot be displaced out of the rack arbitrarily.
b. The lock bracket 40 is laterally adjustable relative to the second rail 26.
c. The lock 202 of the front bracket 200 is provided at the fastening portion of the fastener, so that the lock 202 is positioned in front of the end plate 201 or the column 214, and the position of the screw portion of the lock 212 with respect to the lock 202 can be shortened. The lock base 306 is operatively located at the second lateral position Y2' and in the closed state, wherein the side 320 of the lock base 306 does not interfere with the side 330 of the carrier 328 carried by the second rail 300 because the side 320 of the lock base 306 does not extend beyond the second side M2 of the longitudinal wall 304 of the second rail 300, which is advantageous, for example, in that the side 330 of the carrier 328 can be made as flat as possible with the second side M2 of the longitudinal wall 304 of the second rail 300 to avoid a lateral gap between the side 330 of the carrier 328 and the second side M2 of the longitudinal wall 304 of the second rail 300.
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.
