Abstract
The invention relates to a slide rail assembly, which comprises a first rail, a second rail, a stopper, a workpiece and an operating piece. The stopper is arranged on one of the first rail and the second rail; the workpiece is arranged on the other of the first rail and the second rail; when the second rail moves from a retracted position to an extended position relative to the first rail, the second rail is prevented from moving from the extended position to a retracted direction by the mutual blocking of the workpiece and the stopper; when the operating member is operated, the operating member can contact one of the workpiece and the stopper so as to keep the workpiece and the stopper in a state of not blocking each other.
Description
Technical Field
The present invention relates to a slide rail, and more particularly, to a slide rail assembly capable of releasing the blocking relationship between two slide rails by an operating member.
Background
For example, U.S. patent publication No. US 9,681,749B2 discloses a slide rail assembly including a first rail, a second rail, a stopper, a positioning member and an operating member. The stopper is attached to the first rail; the positioning piece is arranged on the second rail; the operating member is movably connected to the first rail.
When the second rail moves to an extending position relative to the first rail, the second rail can be prevented from being folded from the extending position to a folding direction by the blocking piece blocking the positioning piece; the operating member can be moved from an initial position to a predetermined position by a user applying a force, and in the process of moving to the predetermined position, the operating member can drive the blocking member of the first rail to enable the blocking member to be in an unblocked state and not to block the positioning member any more, so as to allow the second rail to be folded from the extending position to the folding direction.
It should be noted that, since the drawing discloses that the operating member returns to the initial position from the predetermined position through a return elastic member, this also means that once the user stops applying the force to the operating member, the operating member is forcibly brought back to the initial position from the predetermined position in response to the elastic force of the return elastic member.
Therefore, once the user stops applying the force to the operating member, the operating member cannot be kept at the predetermined position, so that the operating member cannot keep keeping the stopper in the unblocked state. However, sometimes this mechanism of forcibly bringing the operating member from the predetermined position back to the initial position by the elastic force of the return elastic member does not satisfy the specific requirements in the market.
Therefore, how to develop a different slide rail product becomes an issue worth discussing.

Preferably, the stopper 38 is located adjacent to the opening 42 of the first rail 30. The stopper 38 includes a connecting portion 44 and a functional portion 46, wherein the connecting portion 44 is connected (e.g., fixed) to the first rail 30, and the functional portion 46 extends from the connecting portion 44. Preferably, the functional portion 46 corresponds to the opening 42 of the first rail 30. Preferably, the functional portion 46 of the stopper 38 includes a guiding section G and a retaining wall B adjacent to the guiding section G (see fig. 3). Preferably, the guiding section G is, for example, a slope or a cambered surface, but the implementation is not limited thereto.

The third rail 34 is displaceable relative to the second rail 32. Preferably, the third rail 34 is movably mounted in a second channel 50 on the second side L2 of the second rail 32.
As shown in fig. 4 and 5, the workpiece 40 is arranged on the other one of the first rail 30 and the second rail 32, here, the workpiece 40 is arranged on the second rail 32 as an example. Preferably, the second rail 32 has an auxiliary opening 51 communicating the first side L1 and the second side L2 of the second rail 32. The working member 40 is movably mounted on the second rail 32, where the working member 40 is pivotally connected to a second side L2 of the second rail 32 via a shaft 52. Preferably, the slide rail assembly further includes an elastic member 54, and the elastic member 54 provides an elastic force to the operating member 40 so that the operating member 40 can maintain a first state S1 in response to the elastic force. Preferably, the working member 40 includes an extension 40a, the extension 40a extends from the second side L2 of the second rail 32 to the first side L1 of the second rail 32, and the extension 40a faces the second side L2 of the first rail 30.
As shown in fig. 6, the slide rail assembly 20 is mounted to the first post 28a and the second post 28b via the first bracket 24 and the second bracket 26. Wherein the linkage feature 36d of the operating member 36 is inserted into one of the plurality of mounting holes H of the first post 28 a.
As shown in fig. 7, the slide rail assembly 20 is in a retracted state. The second rail 32 (and the third rail 34, the third rail 34 is not shown in fig. 7) is located at a retracted position P1 relative to the first rail 30. Wherein the working member 40 of the second rail 32 is at a distance from the stopper 38 of the first rail 30, and the working member 40 is in the first state S1. In addition, the operating member 36 is at a first predetermined position X1. Further, the second rail 32 (and the third rail 34) can be displaced from the retracted position P1 to an opening direction D1 relative to the first rail 30.
As shown in fig. 8 and 9, when the second rail 32 is displaced in the opening direction D1 relative to the first rail 30 (in fig. 8 and 9, only the working member 40 is shown to indicate that the second rail 32 is displaced in the opening direction D1), the extending portion 40a of the working member 40 is guided by the guiding section G of the stopper 38 of the first rail 30, so that the working member 40 is deflected at an angle from the first state S1 and is no longer in the first state S1, and at this time, the elastic member 54 is in a state of accumulating an elastic force. It should be noted that the driving portion 36c of the operating member 36 includes a guiding portion 56. Preferably, the guiding portion 56 is, for example, a slope or a cambered surface, but the implementation is not limited thereto. Preferably, the stopper 38 has a groove 38a, the guiding section G is, for example, a groove edge wall of the groove 38a, and the extending portion 40a of the working member 40 is located in the groove 38 a.
As shown in fig. 10 and 11, when the second rail 32 (in fig. 10 and 11, only the working member 40 is shown to represent the second rail 32) is displaced relative to the first rail 30 in the opening direction D1 to an extended position P2 (see fig. 12), the working member 40 and the stopper 38 are blocked from each other (as shown in fig. 11) to prevent the second rail 32 from being displaced from the extended position P2 to the retracted position P1.
For example, during the process of continuously moving the second rail 32 relative to the first rail 30 in the opening direction D1 to the extended position P2, the extending portion 40a of the working member 40 continues to be guided by the guiding section G of the stopper 38 of the first rail 30 to be displaced along the groove 38a of the stopper 38 (as shown in fig. 10), until the extending portion 40a of the working member 40 reaches the retaining wall B adjacent to the stopper 38, the operating member 40 can be restored from a second state S2 (shown in FIG. 10) to the first state S1 (shown in FIG. 11) in response to the elastic force released by the elastic member 54, so that the operating member 40 is blocked by the retaining wall B through the extended portion 40a, at this time, the second rail 32 is at the extended position P2 (shown in fig. 12) relative to the first rail 30, and is blocked by the wall B of the stopper 38 through the extended portion 40a of the working member 40, for preventing the second rail 32 from being folded from the extended position P2 toward the folded position P1 in a folding direction D2. In addition, the third rail 34 can be displaced relative to the second rail 32 in the opening direction D1 (as shown in fig. 12) to an open position, so that the slide assembly is in an extended state.
As shown in fig. 12 and 13, when the operating member 36 is operated from the first predetermined position X1 (shown in fig. 12, e.g., the initial position) to a second predetermined position X2 (shown in fig. 13, e.g., the non-initial position), the operating member 36 is configured to contact one of the working member 40 and the stopper 38 to maintain the working member 40 and the stopper 38 in a state of no longer blocking each other. In this case, the operating member 36 contacts the working member 40, but is not limited thereto.
Specifically, when the second rail 32 is located at the extended position P2 relative to the first rail 30, a user can apply a force F from the linking feature 36D or the operating portion 36e of the operating member 36 to move the operating member 36 relative to the first rail 30 from the first predetermined position X1 (shown in fig. 12) to the second predetermined position X2 (shown in fig. 13), so that the operating member 36 can contact (e.g., push or press) the extending portion 40a of the working member 40 through the guiding portion 56 of the driving portion 36c to deflect the working member 40 at an angle and is no longer located at the first state S1 (e.g., located at the second state S2), such that the extending portion 40a of the working member 40 is no longer blocked by the retaining wall B of the stopper 38, so as to allow the second rail 32 to move from the extended position P2 (shown in fig. 13) to the retracted position P1 in the retracted direction D2.
It should be noted that, compared to the prior art in which the operation member is arranged with a return elastic member, the operation member 36 of the present embodiment is not arranged with a return elastic member, so that when the user stops applying the force F to the operation member 36, the operation member 36 is not forced to be brought back to the first predetermined position X1 from the second predetermined position X2. This has the advantages that: when the operating element 36 is operated from the first predetermined position X1 to the second predetermined position X2, the operating element 36 can maintain one of the workpiece 40 and the stopper 38 in an unblocked state (e.g., the workpiece 40 is maintained in the second state S2 as the unblocked state) through the driving portion 36c and no longer blocks the other one of the workpiece 40 and the stopper 38 (e.g., the stopper 38), so as to allow the second rail 32 to be retracted from the extended position P2 in the retracting direction D2. In addition, the user can manually return the operating member 36 from the second predetermined position X2 to the first predetermined position X1.
As shown in fig. 14 and 15, the carrier 22 is mounted on a rack by the slide rail assembly 20 and is used in an environment. For example, when the second rail 32 is in the extended position P2 relative to the first rail 30 and the third rail 34 with the carrier 20 mounted thereon is pulled out relative to the second rail 32 to keep the slide rail assembly in the extended state, a first space Y1 is provided between the third rail 34 (or the carrier 22) and an obstruction 58 (e.g., a wall, a door, or other environmental obstruction). However, if the first space Y1 is too narrow, the maintenance of the object 22 or the rail assembly 20 by the user in the field cannot be performed smoothly. Therefore, an operator can operate the operating element 36 to keep the operating element 40 and the stopper 38 in a state of no longer blocking each other (please refer to fig. 13 and its description, which are not described herein), so as to fold the second rail 32 from the extended position P2 to the folded position P1 in the folding direction D2 with respect to the first rail 30, so that a second space Y2 between the third rail 34 (or the carriage 22) and the stopper 58 is wider than the first space Y1, which is beneficial for an on-site operator to detach the carriage 22 or perform maintenance operations related to the slide rail assembly 20.
FIG. 16 shows an operating member 202 of a slide assembly 200 according to another embodiment of the present invention. Further, unlike the operating member 36 disposed on the first side L1 of the first rail 30, the operating member 202 of this embodiment is disposed on the second side L2 of the first rail 30, wherein the operating member 202 can also be used to operate one of the working member 40 and the stopper 38 in a state of no longer blocking each other.
As shown in fig. 17, a plurality of slide rail assemblies 20 are respectively disposed on the upper and lower portions of the left and right sides of the carrier 300. As described above, the operating member 36 of the present embodiment is not provided with the return elastic member, and once operated, can be temporarily held at the position of the original operating state. Therefore, it is not necessary to continuously operate the operating members 36 by multiple persons, that is, when the second rail 32 of the slide rail assemblies 20 is located at the extended position P2 relative to the first rail 30, a single user can apply a force to operate the operating members 36 of the slide rail assemblies 20 from the first predetermined position X1 to the second predetermined position X2, so as to allow the second rail 32 of the slide rail assemblies 20 to be folded from the extended position P2 in the folding direction D2, thereby facilitating the folding operation of the slide rail assemblies 20 or the maintenance operation of the related equipment by a field user or a maintenance person. It should be noted that, in a practical implementation manner, when the third rail 34 is folded from the open position to the folding direction D2, the operating member 36 can also be driven by an ear portion 302 of the supporting object 300 contacting the linking feature 36D of the operating member 36.
From the above description, it can be seen that the enhanced efficacy and advantages of the present invention are:
a. the operating member 36 is operably disposed on the first rail 30, and when the operating member 36 is operated from the first predetermined position X1 to the second predetermined position X2, the operating member 36 is configured to operate one of the working member 40 and the stopper 38 (e.g., operate the working member 40 on the second rail 32) to keep the working member 40 and the stopper 38 in a state of no longer blocking each other, so as to allow the second rail 32 to be displaced from the extended position P2 in the retracting direction D2 to the retracted position P1.
b. Compared to the prior art in which the operating member is arranged with the return elastic member, the operating member 36 of the present embodiment does not have the return elastic member arranged, so that the operating member 36 is not forced to be brought back to the first predetermined position X1 from the second predetermined position X2. This has the advantages that: when the operating member 36 is operated from the first predetermined position X1 to the second predetermined position X2, the operating member 36 can maintain one of the working member 40 and the stopper 38 in an unblocked state without being blocked by the other of the working member 40 and the stopper 38, so as to allow the second rail 32 to be retracted from the extended position P2 in the retracting direction P2.
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.
