Description
Technical Field
The present invention relates to a sliding rail assembly, and more particularly, to a sliding rail assembly between a retracted state and an extended state, wherein a rail of the sliding rail assembly can be easily inserted into other rail of the sliding rail assembly from the front or the rear, both in the retracted state and in the extended state.
Background
Generally, the sliding rail assembly includes a fixed rail and a movable rail movably mounted to a channel of the fixed rail, wherein the fixed rail has a front end and a rear end, the front end and the rear end have a front channel opening and a rear channel opening of the channel, respectively, and a front bracket device and a rear bracket device are disposed in front of and behind the fixed rail, respectively. The fixed rail is mountable to a front column and a rear column of a rack through at least a first mounting member of the front bracket device and at least a second mounting member of the rear bracket device, respectively. The front bracket device or the rear bracket device must have a function of telescopic length to enable at least one first mounting member of the front bracket device to be mounted to the front pillar and at least one second mounting member of the rear bracket device to be mounted to the rear pillar.
Further, taking the function of the rear bracket device having a telescopic length as an example, if the rear bracket device is adjusted to have an extended length such that at least one second mounting member of the rear bracket device and at least one first mounting member of the front bracket device have a predetermined length therebetween, when the at least one second mounting member of the rear bracket device and the at least one first mounting member of the front bracket device are mounted to the rear pillar and the front pillar, respectively, since the front end of the fixed rail is close to the at least one first mounting member (or close to the front pillar), when the movable rail is to be mounted into the channel of the fixed rail from outside the channel of the fixed rail, a user can easily align the movable rail with the front channel opening of the front end of the fixed rail and insert the movable rail into the channel of the fixed rail if standing in front of the at least one first mounting member or the front pillar; however, since the rear bracket device is adjusted to have the extended length, when the at least one second mounting member of the rear bracket device is mounted to the rear pillar, the rear end of the fixed rail is spaced apart from the at least one second mounting member (or spaced apart from the rear pillar), so that when the movable rail is to be mounted into the channel of the fixed rail from outside the channel of the fixed rail, it is difficult (or impossible) to align the movable rail with the rear channel opening of the rear end of the fixed rail and insert the movable rail into the channel of the fixed rail if a user stands behind the at least one second mounting member or the rear pillar.

Preferably, the first rail 28, the second rail 30 and the third rail 32 are located on the same side of the slide rail assembly 20. For example, the sliding rail assembly 20 has a first side and a second side opposite to each other, and the first rail 28, the second rail 30 and the third rail 32 are located on the first side of the sliding rail assembly 20; on the other hand, the first bracket 22, the second bracket 24 and the third bracket 26 are located on the second side of the sliding rail assembly 20.
Preferably, as shown in fig. 2, the first bracket 22 and the second bracket 24 are provided with a first limit feature 58 and a second limit feature 60 that cooperate with each other, and the first limit feature 58 and the second limit feature 60 can block each other when the first bracket 22 and the second bracket 24 are in a first extended position E1 relative to each other (for example, when the second bracket 24 is displaced to the first extended position E1 in a first direction D1 relative to the first bracket 22, this portion can cooperate with fig. 5); on the other hand, the second bracket 24 and the third bracket 26 are provided with a first limiting structure 62 and a second limiting structure 64 that are matched with each other, and when the second bracket 24 and the third bracket 26 are located at a second extending position E2 relative to each other (for example, when the third bracket 26 is displaced to the second extending position E2 in the first direction D1 relative to the second bracket 24, this portion can be matched with fig. 5), the first limiting structure 62 and the second limiting structure 64 can block each other.

Further, when the second bracket 24 is displaced relative to the first bracket 22 in the first direction D1 to the first extended position E1 (see fig. 5 for a portion thereof), the first stop feature 58 and the second stop feature 60 can block each other, so as to prevent the second bracket 24 from being displaced from the first extended position E1 in the first direction D1.
Preferably, as shown in fig. 2, one of the second bracket 24 and the third bracket 26 is provided with a second elastic arm 68, and one of the first limiting structure 62 and the second limiting structure 64 is disposed on the second elastic arm 68. Here, taking the third bracket 26 provided with the second elastic arm 68 as an example, the second limiting structure 64 is a protrusion disposed on the second elastic arm 68; on the other hand, the second bracket 24 is provided with the first limiting structure 62, and the first limiting structure 62 is an opening. Further, when the third support 26 is displaced to the second extended position E2 in the first direction D1 relative to the second support 24 (see fig. 5 for a portion of the second support), the second limiting structure 64 can enter the first limiting structure 62 by the elastic force of the second elastic arm 68, and an inner wall 63 of the first limiting structure 62 and the second limiting structure 64 can block each other to prevent the third support 26 from being displaced from the second extended position E2 to the first direction D1.
The limiting structure between the first bracket 22 and the second bracket 24 adopts a convex-convex matching structure, or the second bracket 24 and the third bracket 26 adopt a convex-hole matching structure, which can be interchanged or mutually arranged, but is not limited to.
Preferably, as shown in fig. 2, the first bracket 22 includes a first portion 70a, a second portion 70b and a longitudinal portion 72 connected between the first portion 70a and the second portion 70b, and the first portion 70a, the second portion 70b and the longitudinal portion 72 together define a first supporting channel 74 for receiving and supporting a portion of the second bracket 24.
Preferably, the second bracket 24 includes a first side 73a, a second side 73b and a longitudinal side 75 connected between the first side 73a and the second side 73b, and the first side 73a, the second side 73b and the longitudinal side 75 together define a second supporting channel 76 for receiving and supporting a portion of the third bracket 26.
Preferably, as shown in fig. 2, the sliding rail assembly 20 further includes a supporting seat 78 disposed on the second bracket 24, the supporting seat 78 has a structural shape matching the second bracket 24, and the supporting seat 78 partially covers the first side 73a, the second side 73b and the longitudinal side 75 of the second bracket 24, so as to help to enhance the supporting strength or the structural strength of the second bracket 24.
Preferably, as shown in fig. 2, the first rail 28 is connected to the first bracket 22 by at least one first connection feature K1 in a predetermined connection manner; the second rail 30 is connected to the second bracket 24 and/or the support base 78 in a predetermined connection manner by at least one second connection feature K2; and the third rail 32 is connected to the third bracket 26 and/or the rear bracket 44 in a predetermined connection by at least one third connection feature K3. The predetermined connection modes can be riveting, welding or clamping, etc., but are not limited in implementation.
Preferably, as shown in fig. 2, the first bracket 22 is a reinforcing seat for reinforcing the structural strength of the first rail 28; the second bracket 24 and the third bracket 26 can be regarded as two telescopic brackets of the second bracket device 20 b.
As shown in fig. 3,4 and 5, the first bracket 22, the second bracket 24 and the third bracket 26 can be longitudinally displaced relative to each other in the first direction D1 or the second direction D2 within a limited range, for example, when the second bracket 24 is displaced relative to the first bracket 22 in the first direction D1 to the first extended position E1 and the third bracket 26 is displaced relative to the second bracket 24 in the first direction D1 to the second extended position E2, the first mounting member 48 of the front bracket 42 and the second mounting member 52 of the rear bracket 44 have a first predetermined length L1 therebetween, and the first rail 28 and the third rail 32 are far away from each other to be in an extended state.
Further, in the extended state, the movable rail 36 may still be mounted to the channel 34 from one of the first rail 28 and the third rail 32. For example, the user can insert the movable rail 36 into the channel 34 from a front channel opening 34a of the first rail 28 (as shown in fig. 3 and 5); alternatively, the user may insert the movable rail 36 into the channel 34 from a rear port 34b of the third rail 32 (as shown in fig. 4). When the movable rail 36 is installed in the channel 34, the movable rail 36 can move in the channel 34 toward the first direction D1 or the second direction D2 (as shown in fig. 5).
As shown in fig. 6, the sliding rail assembly 20 can be mounted on a first column 80a and a second column 80b of a rack, wherein the first column 80a and the second column 80b have a first longitudinal distance therebetween. By the second bracket 24 being in the first extended position E1 relative to the first bracket 22 and the third bracket 26 being in the second extended position E2 relative to the second bracket 24, the first mounting member 48 of the front bracket 42 and the second mounting member 52 of the rear bracket 44 can be matched to the first longitudinal distance by the first predetermined length L1 therebetween, such that the first mounting member 48 can be mounted to the first post 80a and the second mounting member 52 can be mounted to the second post 80b. Preferably, the first fastener 54 can be used to lock the first post 80a of the frame and the second fastener 56 can be used to lock the second post 80b of the frame.
It should be noted that, since the front bracket 42 is disposed adjacent to the front end f of the first rail 28 and the first rail 28 is disposed on the first bracket 22, and since the rear bracket 44 is disposed adjacent to the rear end r of the third rail 32 and the third rail 32 is disposed on the third bracket 26, when the first mounting member 48 of the front bracket 42 and the second mounting member 52 of the rear bracket 44 are mounted to the first post 80a and the second post 80b, respectively, the front end f of the first rail 28 is ensured to be close to the first mounting member 48 (or close to the first post 80 a) and the rear end r of the third rail 32 is ensured to be close to the second mounting member 52 (or close to the second post 80 b) in the extended state in which the first rail 28 and the third rail 32 are relatively far from each other. Accordingly, when a user stands in front of the first mounting member 48 or the first post 80a, the user can still conveniently insert the movable rail 36 from the front channel opening 34a of the first rail 28 to the channel 34; alternatively, the movable rail 36 can be easily mounted to the channel 34 from the rear channel opening 34b of the third rail 32 when a user stands behind the second mounting member 52 or the second post 80b (this portion can also be referred to in conjunction with fig. 3-5 and the description thereof). The design method has the advantages that: when the slide rail assembly is installed on the left and right sides of the frame, the insertion of the movable rail is not affected even if the left and right directions are reversed and the slide rail assembly is adjusted to be in an extended state.
In addition, in the case that the first rail 28 and the third rail 32 are far away from each other and are in the extended state, the length between the front end f of the first rail 28 and the rear end r of the third rail 32 is much longer than the length of the movable rail 36, so the following design is: the track assembly is also in use in a reduced length condition, and therefore the movable track 36 needs to meet both the reduced length condition and the extended condition. Therefore, when the first rail 28 and the third rail 32 are far away from each other and are in the extended state, the length between the front end f of the first rail 28 and the rear end r of the third rail 32 is much longer than the length of the movable rail 36.
In the extended state of the sliding rail assembly 20, the second rail 30 compensates for the empty space or the space left between the first rail 28 and the third rail 32 due to the extension, which is helpful for the movable rail 36 to be inserted into and mounted to the channel 34 from the front channel opening 34a of the first rail 28, so that at least two rail sections (such as a front rail section and a rear rail section) of the movable rail 36 can be supported by the first rail 28 and the second rail 30, and is also beneficial for the movable rail 36 to be displaced toward the first direction D1 so as to be easily guided into the channel 34 of the third rail 32; or facilitates insertion and installation of the movable rail 36 into the channel 34 from the rear channel opening 34b of the third rail 32, so that at least two rail segments (e.g., a front rail segment and a rear rail segment) of the movable rail 36 can be supported by the third rail 32 and the second rail 30, and also facilitates displacement of the movable rail 36 in the second direction D2 for easy introduction into the channel 34 of the first rail 28.
As shown in fig. 7, 8 and 9, when the second bracket 24 is displaced from the first extending position E1 to the second direction D2 to a first folding position R1 relative to the first bracket 22, and the third bracket 26 is displaced from the second extending position E2 to the second direction D2 to a second folding position R2 relative to the second bracket 24, a second predetermined length L2 is smaller than the first predetermined length L1 between the first mounting member 48 of the front bracket 42 and the second mounting member 52 of the rear bracket 44, and at this time, the first rail 28 and the third rail 32 are relatively close to each other and are in a folded state.
Further, in the collapsed state, the movable rail 36 may be mounted to the channel 34 from one of the first rail 28 and the third rail 32. For example, the user can insert the movable rail 36 into the channel 34 from the front channel opening 34a of the first rail 28 (as shown in fig. 7 and 9); alternatively, the user may insert the movable rail 36 into the channel 34 from the rear port 34b of the third rail 32 (as shown in fig. 8). When the movable rail 36 is installed in the channel 34, the movable rail 36 can move in the channel 34 toward the first direction D1 or the second direction D2 (as shown in fig. 9).
As shown in fig. 10, the sliding rail assembly 20 is suitable for the first column 80a and the second column 80b, wherein a second longitudinal distance between the first column 80a and the second column 80b is smaller than the first longitudinal distance. By the second bracket 24 being in the first retracted position R1 relative to the first bracket 22 and the third bracket 26 being in the second retracted position R2 relative to the second bracket 24, the second predetermined length L2 between the first mounting member 48 of the front bracket 42 and the second mounting member 52 of the rear bracket 44 is smaller than the first predetermined length L1, and the second predetermined length L2 can match the second longitudinal distance, such that the first mounting member 48 can be mounted to the first post 80a and the second mounting member 52 can be mounted to the second post 80b. Preferably, the first fastener 54 can be used to lock the first post 80a of the frame and the second fastener 56 can be used to lock the second post 80b of the frame.
It should be noted that, since the front bracket 42 is disposed adjacent to the front end f of the first rail 28 and the first rail 28 is disposed on the first bracket 22, and since the rear bracket 44 is disposed adjacent to the rear end r of the third rail 32 and the third rail 32 is disposed on the third bracket 26, when the first mounting member 48 of the front bracket 42 and the second mounting member 52 of the rear bracket 44 are mounted to the first post 80a and the second post 80b, respectively, the front end f of the first rail 28 is ensured to be close to the first mounting member 48 (or close to the first post 80 a) and the rear end r of the third rail 32 is ensured to be close to the second mounting member 52 (or close to the second post 80 b) in the retracted state in which the first rail 28 and the third rail 32 are relatively close to each other. Accordingly, when a user stands in front of the first mounting member 48 or the first post 80a, the user can conveniently mount the movable rail 36 to the channel 34 from the front channel opening 34a of the first rail 28; alternatively, the movable rail 36 can be easily mounted to the channel 34 from the rear channel opening 34b of the third rail 32 when a user stands behind the second mounting member 52 or the second post 80b (this portion can also be referred to with reference to fig. 7-9 and the description thereof).
In addition, in the case that the first rail 28 and the third rail 32 are close to each other and are in the retracted state, the length between the front end f of the first rail 28 and the rear end r of the third rail 32 in the retracted state is relatively matched (or substantially the same) to the length of the movable rail 36, compared to the case that the first rail 28 and the third rail 32 are in the extended state with respect to each other, so that when the movable rail 36 is mounted to the channel 34 from the front channel opening 34a of the first rail 28 or from the rear channel opening 34b of the third rail 32, at least three rail sections (e.g., a front rail section, a middle rail section, and a rear rail section) of the movable rail 36 can be supported by the first rail 28, the second rail 30, and the third rail 32.
From the above description, it can be seen that the enhancement effect and advantage of the present invention are:

The first rail 28 and the third rail 32 are movable relative to each other by displacement of two members (e.g., the first bracket 22 and the third bracket 26) relative to each other in the extended state or the collapsed state, and in the extended state or the collapsed state, the movable rail 36 is mountable from one of the first rail 28 and the third rail 32 into the channel 34.
2. In the case that the first rail 28 and the third rail 32 are far away from each other and are in the extended state, the second rail 30 can compensate for the empty space or interval between the first rail 28 and the third rail 32, which is helpful for the movable rail 36 to be supported by the first rail 28 and the second rail 30 when the movable rail 36 is mounted to the channel 34 from the front channel opening 34a of the first rail 28, and is also helpful for the movable rail 36 to be guided into the third rail 32 in the first direction D1; or to facilitate the mounting of the movable rail 36 from the rear port 34b of the third rail 32 to the channel 34, such that at least two rail segments (e.g., a front rail segment and a rear rail segment) of the movable rail 36 are supported by the third rail 32 and the second rail 30, and also to facilitate the guiding of the movable rail 36 into the channel 34 of the first rail 28 in the second direction D2.
3. With the first rail 28 and the third rail 32 in the collapsed state in relative proximity to each other, at least three rail segments (e.g., a front rail segment, a middle rail segment, and a rear rail segment) of the movable rail 36 may be supported by the first rail 28, the second rail 30, and the third rail 32 when the movable rail 36 is mounted to the channel 34 from the front access opening 34a of the first rail 28 or from the rear access opening 34b of the third rail 32.
4. Since the front bracket 42 is disposed adjacent the front end f of the first rail 28 and the first rail 28 is disposed on the first bracket 22, and since the rear bracket 44 is disposed adjacent the rear end r of the third rail 32 and the third rail 32 is disposed on the third bracket 26, according to this configuration, when the front bracket 42 and the rear bracket 44 are mounted to the first post 80a and the second post 80b, respectively, the front end f of the first rail 28 can be secured to be close to the first mounting member 48 (or to be close to the first post 80 a), and the rear end r of the third rail 32 can be secured to be close to the second mounting member 52 (or to be close to the second post 80 b). Accordingly, when a user stands in front of the first post 80a, the user can conveniently mount the movable rail 36 to the channel 34 from the front channel opening 34a of the first rail 28; or when a user stands behind the second post 80b, the user can conveniently mount the movable rail 36 to the channel 34 from the rear port 34b of the third rail 32.
5. The supporting seat 78 partially covers the first edge 73a, the second edge 73b and the longitudinal edge 75 of the second bracket 24, which helps to improve the supporting strength or the structural strength of the second bracket 24.
