Description

Slide rail mechanism and slide rail assembly

This invention relates to a slide rail mechanism, and more particularly to a slide rail assembly having an operating element for convenient user operation.

For example, US Patent Publication No. 11,540,630B2 discloses a slide rail assembly comprising a first rail, a second rail, a locking element, and an operating element. When the second rail is in a retracted position relative to the first rail, it is locked relative to the first rail by the locking element to prevent it from leaving the retracted position in an opening direction. The operating element is used to actuate the locking element from the locked state to the unlocked state, preventing the second rail from locking relative to the first rail, thereby allowing it to leave the retracted position in the opening direction.

The operating part of the aforementioned patented operating component is not configured to extend longitudinally in a predetermined direction (e.g., forward or opening direction). Therefore, when the slide rail assembly is applied to a predetermined environment, the operating component may not be easily operated by the user.

Furthermore, Figure 1 illustrates a schematic diagram of the above-mentioned patent application to a frame. Multiple sets of identical slide rail assemblies, for example, a first slide rail assembly 10 and a second slide rail assembly 12, can be mounted at different height positions on a frame 14. Due to the predetermined specifications of the frame 14, when the first slide rail assembly 10 and the second slide rail assembly 12 are installed on the frame 14, the height space U (or operating space) between the bases 18 on the first slide rail assembly 10 and the second slide rail assembly 12 is too narrow. This may make it difficult for the user to insert their fingers into the height space U to operate (e.g., press) the operating part 16a of the operating member 16 on the base 18 of the second slide rail assembly 12. Consequently, it may be difficult for the user to easily disengage the locking relationship when the second rail 15 of the second slide rail assembly 12 is in the retracted position R relative to the first rail 13.

However, in order to meet the diverse needs of the market, how to develop a different type of slide rail product has become an issue that cannot be ignored.

One object of this invention is to provide a slide rail assembly with an operating element that allows the user to easily apply force to release the locking relationship between two slide rails in the retracted position.

According to one aspect of the present invention, a slide rail assembly includes a first rail, a second rail, a stop, a locking element, and an operating element. The second rail and the first rail are longitudinally displaceable relative to each other; the stop is arranged on the first rail; the locking element is movably mounted on the second rail; the operating element includes a driving part and an operating part, the operating part being bent relative to the driving part and extending a predetermined longitudinal distance; wherein, when the second rail is in a retracted position relative to the first rail, the second rail is locked relative to the stop by the locking element. This is used to prevent the second rail from leaving the retracted position in a predetermined direction; wherein, when a force is applied to the operating part of the operating member, causing the operating member to move from a first state to a second state, the driving part of the operating member is used to actuate the locking member from the locked state to an unlocked state, preventing the second rail from locking relative to the stop, thereby allowing the second rail to leave the retracted position in the predetermined direction.

According to another aspect of the present invention, a slide rail assembly includes a first rail, a second rail, a stop, a locking member, and an operating member. The second rail and the first rail are longitudinally displaceable relative to each other; the stop is arranged on the first rail; the locking member is hinged to the second rail via a shaft, and the locking member has a first predetermined portion and a second predetermined portion; the operating member includes a driving portion, an operating portion, and an extension portion, the operating portion being bent relative to the driving portion and extending a predetermined longitudinal distance, the extension portion being on the operating portion and protruding relative to the operating portion; wherein, when the second rail is in a retracted position relative to the first rail, the locking member... In a locked state, the second predetermined portion of the lock engages the stop to prevent the second rail from leaving the retracted position in a predetermined direction. When the operating part of the operating member is activated from a first state to a second state, the driving part of the operating member contacts the first predetermined portion of the lock, causing the lock to transition from the locked state to an unlocked state. This removes the second predetermined portion of the lock from the stop, allowing the second rail to leave the retracted position in the predetermined direction.

According to another aspect of the present invention, a slide rail mechanism is adapted to a frame, the slide rail mechanism comprising a first slide rail assembly and a second slide rail assembly. The first slide rail assembly is arranged at a first height position of the frame; the second slide rail assembly is arranged at a second height position of the frame; wherein each slide rail assembly comprises a first rail, a second rail, a base, a locking member, and an operating member; the first rail is mounted to the frame, and the second rail is longitudinally displaceable relative to the first rail; the base is arranged on the second rail, and the base has a predetermined space; the locking member is located within the predetermined space of the base; The operating component includes a drive unit and an operating unit; wherein, when the first slide rail assembly and the second rail of the second slide rail assembly are in a retracted position relative to the first rail, the second rail is locked relative to the stop by the locking member to prevent the second rail from leaving the retracted position in a predetermined direction; wherein, when the first slide rail assembly and the second rail of the second slide rail assembly are in the retracted position relative to the first rail, the base of the first slide rail assembly... The base of the second slide rail assembly and the second slide rail assembly have a first height gap between them; wherein, when the first slide rail assembly and the second rail of the second slide rail assembly are in the retracted position relative to the first rail, the operating part of the operating member of the first slide rail assembly and the operating part of the operating member of the second slide rail assembly have a second height gap between them that is greater than the first height gap; wherein, through the second height gap, a user's finger can be inserted and operated on the second slide rail. When the operating part of the assembly's operating component applies a force to move the operating component of the second slide rail assembly from a first state to a second state, the driving part of the operating component of the second slide rail assembly actuates the locking member of the second slide rail assembly from the locked state to the unlocked state. This prevents the second rail of the second slide rail assembly from locking relative to the stop of the second slide rail assembly, allowing the second rail of the second slide rail assembly to move away from the retracted position in the predetermined direction.

Overall, the operating mechanism allows the user to easily apply force to release the locking relationship between the two slide rails when they are in the retracted position.

As shown in Figures 2 and 3, a slide rail assembly 20 of one embodiment of the present invention includes a first rail 22 and a second rail 24 that are longitudinally displaceable relative to each other. Preferably, the slide rail assembly 20 further includes a third rail 26 (e.g., a middle rail) movably mounted between the first rail 22 (e.g., an outer rail) and the second rail 24 (e.g., an inner rail). The third rail 26 includes a channel 28 for movably mounting the second rail 24. Here, the X-axis is taken as the longitudinal direction (or the length direction of the slide rail), the Y-axis as the transverse direction (or the side direction of the slide rail), and the Z-axis as the vertical direction (or the height direction of the slide rail) as an example.

Furthermore, the second rail 24 has a front end portion 24a and a rear end portion 24b, and the second rail 24 can be inserted into the channel 28 of the third rail 26 through the rear end portion 24b; on the other hand, the first rail 22 has a front end portion 22a and a rear end portion 22b, and another channel between the front end portion 22a and the rear end portion 22b of the first rail 22 can accommodate the third rail 26.

Preferably, the slide rail assembly 20 further includes a base 30 disposed on the second rail 24, and the base 30 is adjacent to the front end portion 24a of the second rail 24.

Preferably, the lengths of the first rail 22 and the second rail 24 are both longer than the length of the third rail 26. A support member 32 is disposed adjacent to the front end 22a of the first rail 22, and is thus considered part of the first rail 22 as it is connected (e.g., fixed) to it. The support member 32 includes at least one support portion, such as a first support portion 34 and a second support portion 36; when the second rail 24 is in a retracted position R relative to the first rail 22, the first support portion 34 and the second support portion 36 hold the base 30, thereby helping to improve the stability of the front end 24a of the second rail 24 in the retracted position R.

As shown in Figures 2 to 4, the slide rail assembly 20 further includes a stop 38, a locking element 40, and an operating element 42.

The baffle 38 is arranged on the first rail 22. Here, taking the support member 32 on the first rail 22 as an example (as shown in Figure 3), the baffle 38 can be arranged directly on the first rail 22 in alternative embodiments. Therefore, the implementation is not limited.

The locking element 40 and the operating element 42 can be mounted to the base 30 (as shown in Figure 4). Preferably, the base 30 includes a cover 44 (as shown in Figure 3) to shield a portion of the locking element 40 and/or the operating element 42, providing protection.

As shown in Figures 4 and 5, the lock 40 is movably mounted on the second rail 24. Here, the base 30 on the second rail 24 is used as an example, but the implementation is not limited. Preferably, the base 30 has a predetermined space K. The lock 40 is accommodated in the predetermined space K of the base 30. More specifically, the lock 40 is connected to the base 30 on the second rail 24 via a shaft 46. The lock 40 has a first predetermined portion 48 and a second predetermined portion 50 (e.g., a first arm and a second arm), and the shaft 46 is located between the first predetermined portion 48 and the second predetermined portion 50. The second pre-positioned part 50 has a locking section 52 for use with the stop part 38 (as shown in Figure 5).

Preferably, the slide rail assembly 20 further includes an elastic member 54 for providing elastic force to the lock member 40. The elastic member 54 has a first elastic portion 56a, a second elastic portion 56b, and a mounting portion 58 located between the first elastic portion 56a and the second elastic portion 56b. The mounting portion 58 is connected to the shaft member 46, the first elastic portion 56a is adjacent to a first predetermined portion 48 of the lock member 40, and the second elastic portion 56b is connected to a second predetermined portion 50 of the lock member 40.

The operating element 42 is arranged on the second rail 24. Here, it is exemplified that the operating element 42 is movably mounted on the base 30 on the second rail 24, but the implementation is not limited thereto. In this embodiment, the operating element 42 is operably connected to the lock 40 on the base 30.

The operating member 42 includes a drive unit 60 and an operating part 62, the operating part 62 being bent relative to the drive unit 60 and extending a predetermined longitudinal distance M relative to the drive unit 60. Preferably, the drive unit 60 is connected to a first predetermined portion 48 of the lock member 40.

Preferably, the predetermined space K of the base 30 can accommodate the drive unit 60 of the operating member 42, the operating part 62 of the operating member 42 being exposed outside the predetermined space K, and the operating part 62 of the operating member 42 extending longitudinally beyond the drive unit 60 or the predetermined longitudinal distance M of the base 30 in a predetermined direction D1 (e.g., in front of the slide rail assembly or the opening direction).

Preferably, the operating member 42 further includes an extension 64 located on and protruding relative to the operating part 62. More specifically, the extension 64 is bent relative to the operating part 62. Furthermore, the extension 64 of the operating member 42 and the driving part 60 are respectively arranged horizontally relative to the operating part 62 and extend in a first height direction H1 and a second height direction H2; the first height direction H1 and the second height direction H2 are opposite directions. In other words, the extension 64 of the operating member 42 and the driving part 60 extend in different height directions relative to the operating part 62.

Preferably, the extension 64 of the operating member 42 and the driving member 60 are bent substantially perpendicularly to the operating member 62.

Preferably, the base 30 has a front portion 66 and a rear portion 68; the front portion 66 of the base 30 extends beyond the front end portion 24a of the second rail 24 in the predetermined direction D1 (see Figure 2 for reference), and the operating member 42 is located adjacent to the front portion 66 of the base 30; the operating portion 62 of the operating member 42 extends beyond the front portion 66 of the base 30 in the predetermined direction D1.

As shown in Figure 5, the slide rail assembly 20 is in a retracted state. Furthermore, when the second rail 24 is in the retracted position R relative to the first rail 22, the second rail 24 can be locked relative to the stop 38 by the locking member 40 in a locked state S1, preventing the second rail 24 from leaving the retracted position R in the predetermined direction D1.

Specifically, when the second rail 24 is in the retracted position R relative to the first rail 22, the lock 40 is in the locked state S1, causing the locking segment 52 of the second predetermined portion 50 of the lock 40 to lock the stop 38 (or the stop 38 to block the locking segment 52 of the second predetermined portion 50 of the lock 40), thereby preventing the second rail 24 from leaving the retracted position R in the predetermined direction D1.

Preferably, the support member 32 of the first rail 22 has a predetermined structure 70, which protrudes or bulges relative to the support member 32 (see Figure 3 for details), and the predetermined structure 70 has the stop 38. When the second rail 24 is in the retracted position R relative to the first rail 22, the second elastic portion 56b of the elastic member 54 contacts or abuts against a wall of the predetermined structure 70, and the lock member 40 is held in the locked state S1.

As shown in Figures 5 and 6, when a force F (e.g., a pressing force) is applied to the operating part 62 of the operating member 42, causing the operating member 42 to move from a first state J1 (as shown in Figure 5) to a second state J2 (as shown in Figure 6), the driving part 60 of the operating member 42 drives the locking member 40 from the locked state S1 (as shown in Figure 5) to the unlocked state S2 (as shown in Figure 6), preventing the second rail 24 from locking relative to the stop 38, thus allowing the second rail 24 to leave the retracted position R in the predetermined direction D1 relative to the first rail 22.

Specifically, when the operating part 62 of the operating member 42 is operated to move from the first state J1 to the second state J2, the driving part 60 of the operating member 42 can contact and press the first predetermined part 48 of the lock member 40, thereby driving the lock member 40 from the locked state S1 to a predetermined rotation direction r to the unlocked state S2. This causes the locking segment 52 on the second predetermined part 50 of the lock member 40 to no longer lock the stop 38 (or the stop 38 to no longer block the locking segment 52 of the second predetermined part 50 of the lock member 40), allowing the second rail 24 to leave the retracted position R relative to the first rail 22 in the predetermined direction D1.

As shown in Figure 7, once the lock 40 is in the unlocked state S2, the second rail 24 can be displaced relative to the first rail 22 from the retracted position R to an extended position D1. During this extension, the second elastic portion 56b of the elastic member 54 no longer contacts or abuts against the wall of the predetermined structure 70.

It is worth mentioning that the second rail 24 can return from the extended position E to the retracted position R (as shown in Figure 5) relative to the first rail 22, in another predetermined direction D2 opposite to the predetermined direction D1 (e.g., behind the slide rail assembly or in the retracting direction).

As shown in Figure 8, the slide rail assembly 20 further includes a safety element 72 to prevent the locking element 40 from moving from the locked state S1 to the unlocked state S2.

For example, the base 30 has an opening 74 connecting to the predetermined space K, and the safety member 72 includes a connecting portion 76. When the connecting portion 76 of the safety member 72 passes through (or is inserted into) the opening 74 into the predetermined space K, the connecting portion 76 of the safety member 72 can prevent the lock 40 from moving from the locked state S1 to the unlocked state S2. More specifically, when the connecting portion 76 of the safety member 72 is inserted into the opening 74, the connecting portion 76 of the safety member 72 can be used to block the movement path of either the lock member 40 or the operating member 42. For example, blocking the movement path of the operating member 42, in this case, even if the operating part 62 of the operating member 42 is subjected to the aforementioned force F, because the driving part 60 of the operating member 42 is blocked by the connecting portion 76 of the safety member 72, the operating member 42 cannot move from the first state J1 to the second state J2, and the driving part 60 of the operating member 42 cannot be pressed. The first predetermined portion 48 of the lock 40 prevents the lock 40 from transitioning from the locked state S1 to the unlocked state S2, keeping the locking segment 52 on the second predetermined portion 50 of the lock 40 locked to the stop 38. This reliably prevents the second rail 24 from leaving the retracted position R in the predetermined direction D1 relative to the first rail 22. Accordingly, the safety element 72 provides the slide rail assembly 20 with a safety mechanism to ensure the reliability of the second rail 24 being locked in the retracted position R by the lock 40 in the locked state S1 relative to the first rail 22.

As shown in Figure 9, in one application, a slide rail mechanism can be mounted on a frame 78. This slide rail mechanism includes at least two slide rail assemblies, such as a first slide rail assembly 202 and a second slide rail assembly 204. The structure of the first slide rail assembly 202 and the second slide rail assembly 204, and the arrangement of their components, are the same as those of the slide rail assembly 20 described above (i.e., the first slide rail assembly 202 and the second slide rail assembly 204 can be considered as two sets of the aforementioned slide rail assemblies 20). For simplicity, further details are omitted here.

Furthermore, the first slide rail assembly 202 is arranged at a first height position Q1 of the frame 78, while the second slide rail assembly 204 is arranged at a second height position Q2 of the frame 78, different from the first height position Q1. For example, the second height position Q2 is lower than the first height position Q1, but the implementation is not limited.

The first rails 22 of both the first slide rail assembly 202 and the second slide rail assembly 204 are mounted (e.g., fixed) to the frame 78, and the second rails 24 of both the first slide rail assembly 202 and the second slide rail assembly 204 can be used to support a load (not shown).

When the second rails 24 of both the first slide rail assembly 202 and the second slide rail assembly 204 are in the retracted position R relative to the first rail 22, the second rail 24 is locked relative to the stop 38 by the locking member 40 in the locked state S1, preventing the second rail 24 from leaving the retracted position R in the predetermined direction D1 (this part can be referred to in conjunction with Figure 5).

Furthermore, when the first slide rail assembly 202 and the second slide rail assembly 204 are in the retracted position R relative to the first slide rail 22, the base 30 of the first slide rail assembly 202 and the base 30 of the second slide rail assembly 204 have a first height space U1 between them.

When the first slide rail assembly 202 and the second slide rail assembly 204 are in the retracted position R relative to the first track 22, the operating portions 62 of the operating members 42 of the first slide rail assembly 202 and the operating portions 62 of the operating members 42 of the second slide rail assembly 204 have a second height space U2 (or second operating space) greater than the first height space U1 (or first operating space) between them.

Because the second height space U2 is larger than the first height space U1, compared to the first height space U1, a user's finger f can easily reach into the second height space U2 and apply force F to the operating part 62 of the operating member 42 of the second slide rail assembly 204. When the operating member 42 of the second slide rail assembly 204 moves from the first state J1 to the second state J2, the driving part 60 of the operating member 42 of the second slide rail assembly 204 is used to drive the locking member 40 of the second slide rail assembly 204 from the locked state S1 to the unlocked state. State S2 prevents the second rail 24 of the second slide rail assembly 204 from locking relative to the stop 38 of the second slide rail assembly 204, thereby allowing the second rail 24 of the second slide rail assembly 204 to leave the retracted position R in the predetermined direction D1 (the principle of how the operating member 42 moves from the first state J1 to the second state J2, how the locking member 40 changes from the locked state S1 to the unlocked state S2, and how the second rail 24 can leave the retracted position R in the predetermined direction D1 can be referred to Figures 5 and 6, and will not be elaborated here for the sake of simplicity). In other words, the user's finger f does not need to extend into the first height space U1, which is relatively smaller than the second height space U2, to apply force F to the operating part 62 of the operating member 42 of the second slide rail assembly 204, to operate the lock 40 of the second slide rail assembly 204 to change from the locked state S1 to the unlocked state S2.

Therefore, the slide rail assembly package 20 provided by the embodiments of the present invention has the following characteristics:

1. The operating part 62 of the operating member 42 extends longitudinally beyond the drive unit 60 or the base 30 by a predetermined longitudinal distance M in the predetermined direction D1 (e.g., in front of the slide rail assembly or in the opening direction). In other words, the operating part 62 of the operating member 42 extends the predetermined longitudinal distance M in the predetermined direction D1, making it easier and more convenient for the user's fingers to apply the force F to the operating part. The operating part 62 of component 42 extends the predetermined longitudinal distance M in the predetermined direction D1, which can be regarded as lengthening the lever arm of the first predetermined part 48 of the lock 40. This allows the user to operate the lock 40 from the locked state S1 to the unlocked state S2 with less effort by using the operating part 62 of the operating part 42.

2. After the lock 40 transitions from the locked state S1 to the unlocked state S2, the user can easily apply force through the extension 64 of the operating member 42 to pull the second rail 24 (and its load) relative to the first rail 22 from the retracted position R in the predetermined direction D1.

3. The safety element 72 provides the slide rail assembly 20 with a safety mechanism to ensure the reliability of the second rail 24 being locked in the retracted position R relative to the first rail 22 by the locking element 40 in the locked state S1.

Although the present invention has been disclosed by the foregoing preferred embodiments, these are not intended to limit the scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended patent claims.

The extension portion is on the operating part and protrudes relative to the operating part; wherein, when the second rail is in a retracted position relative to the first rail, the lock is in a locked state, causing the second predetermined portion of the lock to lock the stop, thereby preventing the second rail from leaving the retracted position in a predetermined direction; wherein, when the operating part of the operating member is operated to move from a first state to a second state... The driving part of the operating element contacts the first predetermined part of the lock to actuate the lock from the locked state to an unlocked state, causing the second predetermined part of the lock to no longer lock the stop, thereby allowing the second rail to move away from the retracted position in the predetermined direction; wherein, the driving part of the operating element is connected to the first predetermined part of the lock; the slide rail assembly further includes a base arranged on the second rail, The base has a predetermined space to accommodate the driving portion of the locking element and the operating element, the operating portion of the operating element being exposed outside the predetermined space and extending longitudinally beyond the base in the predetermined direction; wherein, the slide rail assembly further includes a safety member; when the safety member enters the predetermined space of the base, the safety member prevents the locking element from moving from the locked state to the unlocked state. The slide rail assembly as described in claim 10, wherein the extension of the operating member and the drive portion extend in different height directions relative to the operating member. The slide rail assembly as described in claim 10 further includes a third rail movably mounted between the first rail and the second rail. A slide rail mechanism, adapted for a frame, includes: a first slide rail assembly arranged at a first height position of the frame; and a second slide rail assembly arranged at a second height position of the frame; wherein each slide rail assembly includes a first rail, a second rail, a base, a stop, a locking member, and an operating member; the first rail is mounted to the frame, the stop is arranged on the first rail, and the second rail is longitudinally displaceable relative to the first rail; the base is arranged on the second rail. The base has a predetermined space; the locking member is located within the predetermined space of the base; the operating member includes a driving part and an operating part; wherein, when the second rail of the first slide rail assembly and the second rail of the second slide rail assembly are in a retracted position relative to the first rail, the second rail is locked relative to the stop by the locking member to prevent the second rail from leaving the retracted position in a predetermined direction; wherein, when the second rail of the first slide rail assembly and the second rail of the second slide rail assembly are in a retracted position relative to the first rail, the second rail is locked relative to the stop by the locking member to prevent the second rail from leaving the retracted position in a predetermined direction; wherein, when the second rail of the first slide rail assembly and the second rail of the second slide rail assembly are in a retracted position relative to the first rail, the second rail is locked relative to the stop by the locking member to prevent the second rail from leaving the retracted position in a predetermined direction. When the rails are in the retracted position, there is a first height gap between the base of the first slide rail assembly and the base of the second slide rail assembly; wherein, when the second rails of the first slide rail assembly and the second slide rail assembly are in the retracted position relative to the first rail, there is a second height gap between the operating parts of the operating components of the first slide rail assembly and the operating parts of the operating components of the second slide rail assembly, which is greater than the first height gap; wherein, the second height gap provides a space for a user's hand. A force is applied to the operating part of the operating component of the second slide rail assembly, causing the operating component to move from a first state to a second state. The driving part of the operating component then actuates the locking element of the second slide rail assembly from a locked state to an unlocked state, preventing the second rail of the second slide rail assembly from locking relative to the stop of the second slide rail assembly. This allows the second rail of the second slide rail assembly to move away from the retracted position in the predetermined direction. The slide mechanism as described in claim 13, wherein the second track has a front end and a rear end; a base of each slide assembly is adjacent to the front end of the second track, and a predetermined space of the base of each slide assembly is further capable of accommodating the drive portion of the operating member, the operating portion of the operating member being exposed outside the predetermined space, and the operating portion of the operating member extending longitudinally beyond the base in the predetermined direction. The slide mechanism as described in claim 14, wherein each slide assembly further includes an elastic element for providing elastic force to the lock; and the operating element of each slide assembly further includes an extension bent relative to the operating element. The slide mechanism as described in claim 14, wherein each slide assembly further includes a safety element; when the safety element is inserted into the predetermined space of the base, the safety element prevents the lock from moving from the locked state to the unlocked state.
