Description
Technical Field
The present invention relates to a slide rail, and more particularly, to a synchronization system, a synchronization device and a synchronization method for a slide rail.
Background
In a furniture system, a drawer is typically easily opened and closed relative to a cabinet by a pair of rail assemblies. Technology capable of assisting a drawer to be opened by being pressed relative to a cabinet when the drawer is folded relative to the cabinet is available on the market, namely, a product of so-called Push-open. Specifically, when the movable rail of the slide rail assembly is located at a retracted position relative to the fixed rail, a user can press the drawer carried by the movable rail, so that the movable rail moves from the retracted position toward an overpressure position in a closing direction relative to the fixed rail fixed to the cabinet, and when the overpressure position is reached, an elastic member of an opening mechanism of the slide rail assembly is unlocked, and the elastic member releases elastic force to drive the movable rail and the drawer to open in an opening direction.
Further, a synchronization system for a slide rail assembly is disclosed in U.S. Pat. No. 5, 10,172,459, 2. The synchronous system is applied to the slide rail assembly with the push type opening technology. Further, the synchronization system is disposed on a first slide rail assembly and a second slide rail assembly. The synchronization system comprises a first synchronization device, a second synchronization device and a synchronization rod. The first synchronization device is arranged on the first slide rail assembly; the second synchronization device is arranged on the second slide rail assembly; the synchronization rod is movably installed between the first synchronization device and the second synchronization device. Wherein, when the movable rail of the first slide rail assembly of the above-mentioned patent is pressed by a force applied by a user to move from a retracted position (as shown in fig. 11 of the patent) to an excessive pressure position (as shown in fig. 13 and 14 of the patent) in a closing direction relative to the fixed rail of the first slide rail assembly, the locking component of an opening mechanism of the first slide rail assembly is driven to release the elastic component of the opening mechanism, so that the elastic component of the opening mechanism of the first slide rail assembly releases the elastic force to drive the movable rail of the first slide rail assembly to move in an opening direction, wherein, in this type of slide rail technology, if the user continuously presses the movable rail of the first slide rail assembly by the force, the movable rail of the first slide rail assembly is not driven in the opening direction by the elastic component of the opening mechanism, but the synchronization rod simultaneously drives the driving component of the second synchronization device of the second slide rail assembly, the locking part of the other opening mechanism of the second slide rail assembly is driven to unlock the elastic part of the other opening mechanism, and the elastic part of the second slide rail assembly releases the elastic force, so that the movable rail of the second slide rail assembly is driven to lift up to the opening direction relative to the movable rail of the first slide rail assembly pressed by the force to be opened. In addition, in the driving method of the slide rail, since the movable rail of the first slide rail assembly is pressed and the elastic member of the second slide rail assembly is interlocked to release the elastic force for driving the movable rail of the second slide rail assembly, it is inevitable that an unexpected noise phenomenon is generated, and therefore, with the difference of market demands, how to develop a different slide rail synchronization product to allow the market to have more choices becomes an issue that cannot be ignored.

Detailed Description
As shown in FIG. 1, a piece of furniture 20 includes a first slide rail assembly 22 and a second slide rail assembly 24. Further, the furniture 20 includes a first furniture member 26 and a second furniture member 28. The first furniture member 26 can be a cabinet, and the second furniture member 28 can be a drawer, but is not limited to this embodiment. The first and second track assemblies 22 and 24 are used for mounting the second furniture member 28, so that the second furniture member 28 can be easily displaced relative to the first furniture member 26 via the first and second track assemblies 22 and 24.
As shown in fig. 2, the first slide rail assembly 22 and the second slide rail assembly 24 have substantially the same structural configuration and are respectively installed on two sides of the first furniture member 26. Specifically, the first and second slide assemblies 22, 24 each include a first rail 30 (e.g., a fixed rail) and a second rail 32 (e.g., a movable rail) that are longitudinally displaceable relative to the first rail 30. Preferably, a third rail 34 (e.g., a middle rail) is movably mounted between the first rail 30 and the second rail 32 for extending the displacement stroke of the second rail 32 relative to the first rail 30. Wherein the first rail 30 is fixedly mounted to the first furniture member 26, and the second rail 32 is used for carrying the second furniture member 28 (see fig. 1). The embodiment of the present invention provides a synchronization system including a first synchronization device 36 and a second synchronization device 200 suitable for the furniture 20.
The first synchronization device 36 is disposed on the first slide assembly 22, such as the second rail 32 of the first slide assembly 22; on the other hand, the second synchronization device 200 is disposed on the second slide assembly 24, such as the second rail 32 of the second slide assembly 24. Further, the synchronization system further includes a synchronization rod 38 movably disposed between the first synchronization device 36 and the second synchronization device 200. Preferably, a first end 38a and a second end 38b of the synchronization rod 38 are detachably mounted to the first synchronization device 36 and the second synchronization device 200, respectively.
As shown in fig. 3, 4 and 5, the first synchronization device 36 and the second synchronization device 200 have substantially the same structural configuration. Only the first synchronization device 36 will be described herein. Further, the first synchronizer 36 (also referred to as synchronizer) includes a driving member 40. Preferably, the device further includes a base 42, an actuating member 44, a first elastic member 46, a second elastic member 48, a housing 50, a mounting seat 52, a sleeve 54 and an operating member 56.
The base 42 includes a first portion 42a and a second portion 42 b. Preferably, the second portion 42b is substantially perpendicularly bent with respect to the first portion 42 a.
The drive member 40 is movably mounted to the base 42. Here, the driving member 40 is pivoted to the base 42 by a first shaft 58, for example, the driving member 40 is pivoted to one side (for example, a top side, but not limited in implementation) of the first portion 42a of the base 42 by the first shaft 58. Preferably, the driving member 40 has a chamber 45 for accommodating at least a portion of the actuating member 44. Preferably, the chamber 45 is a channel disposed transverse to the longitudinal length of each of the rail assemblies.
The actuating member 44 is movable relative to the actuating member 40. For example, the actuator 44 is linearly displaceable relative to the driver 40 via a chamber 45 of the driver 40.
The first elastic member 46 is elastically loaded to the actuating member 44. Preferably, the first elastic member 46 is disposed in the accommodating chamber 45 of the driving member 40, and the first elastic member 46 is used for providing an elastic force to the actuating member 44.
The second elastic member 48 is used to provide elastic force to the driving member 40. Specifically, the driving member 40 can be maintained in an initial state in response to the elastic force of the second elastic member 48. Preferably, the second elastic member 48 is a return spring, and two ends of the second elastic member 48 are respectively connected to a first connecting portion 60 of the driving member 40 and a second connecting portion 62 of the base 42.
The housing 50 covers a portion of the driving member 40. Here, the housing 50 covers almost all of the driving member 40, but the embodiment is not limited thereto. Preferably, the housing 50 at least protects the driving member 40, the actuating member 44, the first elastic member 46 and the second elastic member 48 from being damaged by external factors (such as dust or moisture).
The mounting seat 52 is disposed on the second portion 42b of the base 42. Here, the mounting base 52 is connected to the second portion 42b of the base 42 through at least one connecting member (e.g., a first connecting member 64a and a second connecting member 64 b). Preferably, the mounting base 52 includes a space 66.
The sleeve 54 is rotatably mounted to the mount 52. Preferably, the sleeve 54 includes a base 54a and an extension 54 b. A portion 54c of the base 54a is received in the space 66 of the mount 52, and the extension 54b extends from the base 54a away from the portion 54 c. Wherein the first end 38a of the synchronization rod 38 is connected to the extension 54 b. Preferably, the portion 54c of the base 54a has a first section W1 and a second section W2 for cooperating with a driving portion 40a of the driving member 40 and a working wall 56a of the working member 56, respectively. The first section W1 and the second section W2 are, for example, protrusions or walls, but are not limited thereto.
The working member 56 is pivotally connected to the base 42 via a second shaft 68, for example, the working member 56 is pivotally connected to the other side (e.g. the bottom side) of the first portion 42a of the base 42 via the second shaft 68. Thus, the driving member 40 and the operating member 56 are located on different sides of the first portion 42a of the base 42.
As shown in fig. 6 and 7, the driving member 40, the actuating member 44, the first elastic member 46 and the second elastic member 48 of the first synchronization device 36 are located at one side (e.g., top side, as shown in fig. 6) of the first portion 42a of the base 42, and the working member 56 of the first synchronization device 36 is located at the other side (e.g., bottom side, as shown in fig. 7) of the first portion 42a of the base 42. Further, the driving member 40, the actuating member 44, the first elastic member 46, the second elastic member 48, the sleeve 54, the synchronization rod 38 and the operating member 56 are in an initial state respectively when not receiving a force.
As shown in fig. 8 and 9, when the actuating member 44 receives the force F (e.g., an external force or an acting force), the driving member 40 is driven to rotate in a pivoting direction C by an angle (as shown in fig. 8) in response to the actuating member 44 receiving the force F, and the driving portion 40a of the driving member 40 can push against the first section W1 of the sleeve 54 to drive the sleeve 54 and the synchronization rod 38 to rotate in a predetermined rotating direction K by an angle. When the sleeve 54 rotates in the predetermined rotation direction K, the second section W2 of the sleeve 54 pushes against the working wall 56a of the working member 56, so that the working member 56 is driven to rotate by an angle (as shown in fig. 9).
It should be noted that when the driving member 40 rotates in the pivoting direction C in response to the force F (as shown in fig. 8), the second elastic member 48 is in a state of accumulating an elastic force. Once the force F is stopped (or no longer applied), the driving member 40 can return to the initial state (as shown in fig. 6) in response to the second elastic member 48 releasing the elastic force. In addition, as shown in fig. 6, the housing 50 has a stop feature 70, such as a wall, for preventing rotation of the driving member 40 in another pivoting direction (i.e., a direction opposite to the pivoting direction C).
As shown in fig. 10, the second rail 32 and the third rail 34 of the first slide assembly 22 are in an extended state relative to the first rail 30. Preferably, the first slide assembly 22 further comprises a carrier 72 and a base 74. The carrier 72 is fixedly attached to and adjacent to the second rail 32 of the first slide assembly 22; on the other hand, the base 74 is fixed to the bottom of the carrier 72. Thus, the carrier 72 and the base 74 can be considered part of the second rail 32 of the first slide assembly 22.
The base 74 includes a releasing portion 74a and a locking portion 74 b. Here, the detent releasing portion 74a and the detent portion 74b are exemplified by guide grooves communicating with each other. Further, the releasing portion 74a has a predetermined longitudinal length, and the locking portion 74b is bent at an angle relative to the releasing portion 74a (this portion can be seen in fig. 11).
Further, the first slide assembly 22 further includes a first opening mechanism. The first opening mechanism includes a resilient member 78 and a locking member 80 for temporarily locking the resilient member 78. The locking element 80 of the first opening mechanism can lock the elastic element 78 of the first opening mechanism through the locking part 74b of the base 74, and the locking element 80 of the first opening mechanism can no longer lock the elastic element 78 of the first opening mechanism through the releasing part 74a of the base 74.
Preferably, the base 74 further includes a space S, and the first slide assembly 22 further includes a slide member 82. The slide member 82 is received in a portion of the space of the base 74, and the slide member 82 and the base 74 are longitudinally displaceable relative to each other through the space S. Preferably, a cover 82a is connected (e.g., fixed) to the rail member 82 and can be considered as a part of the rail member 82, and the locking element 80 can be movably disposed between the rail member 82 and the cover 82a (see fig. 13). The locking element 80 includes a first leg 80a and a second leg 80 b. The first leg 80a is pivotally connected to the slide rail part 82, and the second leg 80b can be locked to the locking portion 74b of the base 74 (see fig. 11). When the second leg 80b is engaged with the engaging portion 74b of the base 74, the locking member 80 can be used to lock the elastic member 78, so that the elastic member 78 maintains an elastic force; when the second leg 80b is released from the detent portion 74b of the base 74 and enters the release portion 74a of the base 74, the locking member 80 no longer locks the elastic member 78, so that the elastic member 78 releases the elastic force. Preferably, the first slide rail assembly 22 further includes a movable member 84. The movable member 84 and the supporting member 72 can be longitudinally displaced relative to each other, and the movable member 84 is disposed at the bottom of the supporting member 72. Preferably, the movable member 84 and the carrier member 72 are displaceable within a limited range relative to each other by engagement of a projection 86 with a bounded longitudinal slot 88, wherein the projection 86 extends through a portion of the longitudinal slot 88. Preferably, the resilient member 78 is disposed between the movable member 84 and the base 74. Here, the elastic element 78 is taken as an example of a spring, and two ends of the spring are respectively connected to the movable element 84 and the base 74, but the implementation is not limited thereto.
Furthermore, the cover 82a of the slide rail part 82 is provided with an auxiliary member 90, and the auxiliary member 90 includes a first contact portion 90 a. Preferably, the first portion 42a of the base 42 of the first synchronization device 36 includes at least one first latching feature 92, and the at least one first latching feature 92 is configured to be mutually latched with at least one second latching feature 94 of the carrier 72 of the second rail 32 of the first slide assembly 22, such that the first synchronization device 36 is detachably mounted to the carrier 72 (see fig. 10 and 12). In other words, the first synchronization device 36 is detachably mounted to the second rail 32 of the first slide assembly 22. Similarly, the second synchronization device 200 is removably mounted to the second rail 32 of the second slide assembly 24.
As shown in fig. 14, the first slide assembly 22 and the second slide assembly 24 have substantially the same structural configuration, and the first synchronization device 36 and the second synchronization device 200 have substantially the same structural configuration. The synchronization rod 38 is movably disposed between the first synchronization device 36 and the second synchronization device 200, and the first slide assembly 22 and the second slide assembly 24 respectively include the first opening mechanism and a second opening mechanism. The second opening mechanism and the first opening mechanism have substantially the same structural configuration, for example, the second opening mechanism includes an elastic member 202 and a locking member 204 for locking the elastic member 202, and the matching operation principle of the elastic member 202 and the locking member 204 is the same as that of the elastic member 78 and the locking member 80 of the first opening mechanism, and for the sake of brevity, further description is omitted here.
Further, the second rails 32 of the first and second slide assemblies 22 and 24 are both in a retracted position R relative to the first rail 30. The related components of the first synchronization device 36 and the second synchronization device 200 are in the initial state, which can be referred to as the initial state of the first synchronization device 36 shown in fig. 15 as an example. Further, the first leg 80a of the locking element 80 of the first opening mechanism is pivotally connected to the slide rail part 82, and the second leg 80b of the locking element 80 can be clamped to the clamping portion 74b of the base 74, so that the locking element 80 can be used to lock the elastic element 78, and the elastic element 78 can maintain an elastic force. Similarly, the locking element 204 of the second slide rail assembly 200 can be used to lock the resilient element 202 (as shown in fig. 14). In addition, as shown in fig. 15, when the first rail assembly 22 and the second rail 32 of the second rail assembly 24 are both located at the retracted position R relative to the first rail 30, a second contact portion 44a of the actuating member 44 of the first synchronization device 36 is located at a side corresponding to the first contact portion 90a of the auxiliary member 90. Wherein the actuator 44 is in a first predetermined position. Preferably, one of the first contact portion 90a of the auxiliary member 90 and the second contact portion 44a of the actuating member 44 is an inclined surface or an arc surface. Here, the first contact portion 90a and the second contact portion 44a are both inclined surfaces, but the implementation is not limited thereto.
As shown in fig. 16, the movable member 84 can be temporarily engaged with a locking feature of an extending seat 30a of the first rail 30 relative to the carrier member 72 (for brevity, the description is omitted here). In addition, in fig. 16, the protrusion 86 is not shown.
As shown in fig. 16, 17 and 18, when the user applies a pressing force F1 in a first direction D1 to the second rail 32 of the first slide assembly 22 to displace the second rail 32 of the first slide assembly 22 relative to the first rail 30 of the first slide assembly 22 from the retracted position R in the first direction D1 (e.g., the closing direction) to an overpressure position X, the base 74 moves in the first direction D1 accordingly, so that the locking element 80 of the first opening mechanism can be driven by the base 74 through the second leg 80b, and the locking element 80 pivots through the first leg 80a to swing at an angle to allow the second leg 80b to be released from the catching portion 74b of the base 74, and the second leg 80b enters the releasing portion 74a of the base 74, so that the locking element 80 of the first opening mechanism no longer locks the elastic element 78 of the first opening mechanism. On the other hand, when the second rail 32 of the first slide assembly 22 is displaced from the retracted position R to the overpressure position X along the first direction D1 relative to the first rail 30 of the first slide assembly 22, the second contact portion 44a of the actuating member 44 and the first contact portion 90a of the auxiliary member 90 contact each other to generate a force, so that the actuating member 44 can be displaced from the first predetermined position to a second predetermined position along the first transverse direction T1 relative to the actuating member 40 in response to the force, and the second contact portion 44a of the actuating member 44 is staggered from the first contact portion 90a of the auxiliary member 90, at which time the first elastic member 46 is in a state of accumulating an elastic force (as shown in fig. 17), until the second rail 32 of the first slide assembly 22 is at the overpressure position X relative to the first rail 30 of the first slide assembly 22 (as shown in fig. 18), the second contact portion 44a of the actuating member 44 has completely passed over the first contact portion 90a of the auxiliary member 90 Reaching the other side of the first contact portion 90a of the auxiliary member 90 (as shown in fig. 18), at this time, the first elastic member 46 releases the elastic force, so that the actuating member 44 is displaced from the second predetermined position to a second transverse direction T2 (opposite to the direction of the first transverse direction T1) back to the first predetermined position (as shown in fig. 18) in response to the elastic force released by the first elastic member 46, at this time, the position of the second contact portion 44a of the actuating member 44 corresponds to the other side of the first contact portion 90a of the auxiliary member 90. It should be noted that when the second rail 32 of the first slide rail assembly 22 is located at the overpressure position X relative to the first rail 30 of the first slide rail assembly 22, the related components of the second synchronization device 200 are still in the above-mentioned initial state.
As shown in fig. 19, once the user stops applying the pressing force F1 in the first direction D1 to the second rail 32 of the first slide assembly 22, the elastic member 78 of the first opening mechanism releases a first elastic force in a second direction D2 (opposite to the first direction D1, for example, the opening direction) to drive the second rail 32 of the first slide assembly 22 to move from the over-pressure position X to the second direction D2 relative to the first rail 30 of the first slide assembly 22.
As shown in fig. 19, 20 and 21, when the second rail 32 of the first slide rail assembly 22 moves from the overpressure position X to the second direction D2 to a predetermined stroke, the driving member 40 of the first synchronization device 36 is driven (as shown in fig. 20) to drive the synchronization rod 38 to drive the working member 206 of the second synchronization device 200, so as to drive the locking member 204 of the second opening mechanism to no longer lock the elastic member 202 of the second opening mechanism (as shown in fig. 21), so that the elastic member 202 of the second opening mechanism releases a second elastic force to drive the second rail 32 of the second slide rail assembly 24 to move toward the second direction D2 relative to the first rail 30 of the second slide rail assembly 24.
Specifically, when the second rail 32 of the first slide rail assembly 22 moves from the overpressure position X to the second direction D2 to a predetermined stroke, the second contact portion 44a of the actuator 44 in the first predetermined position pushes against the first contact portion 90a of the auxiliary member 90 to generate a force (for example, the force F, which can be referred to in fig. 8), so that the driving member 40 of the first synchronizer 36 is driven to rotate by the angle from the initial state to the pivot direction C (as shown in fig. 20) to drive the sleeve 54 of the first synchronizer 36 and the synchronization rod 38 to rotate by the angle to the predetermined rotation direction K, so that the second end 38b of the synchronization rod 38 passes through the first section W1 of the sleeve 208 of the second synchronizer 200 to rotate the working member 206 of the second synchronizer 200 (as shown in fig. 21), so as to drive the locking member 204 of the second opening mechanism, the second leg 204b of the locking element 204 of the second opening mechanism is away from the latching portion 210b of the base 210 of the second slide assembly 24, and the second leg 204b enters the releasing portion 210a of the base 210, so that the locking element 204 of the second opening mechanism no longer locks the elastic element 202 of the second opening mechanism, and the elastic element 202 of the second opening mechanism releases the second elastic force, so as to drive the second rail 32 of the second slide assembly 24 to move along the second direction D2 along with the second rail 32 of the first slide assembly 22.
It should be noted that the present invention also provides a driving method for the slide rail assemblies 22 and 24, which is disclosed in the above embodiments and therefore not described herein for brevity.
From the above description, it can be seen that the enhanced efficacy and advantages of the present invention are:
a. unlike the prior art, the embodiment discloses that when the second rail 32 of the first slide assembly 22 is displaced from a retracted position R to an overpressure position X by applying the pressing force F1 to the first rail 30 of the first slide assembly 22, the second rail 32 of the second slide assembly 24 is not opened in advance in the second direction D2 relative to the second rail 32 of the first slide assembly 22. Further, when the user stops applying the force F1, the second rail 32 of the first slide rail assembly 22 is opened to a predetermined stroke in the second direction D2 at the overpressure position X in response to the elastic member 78 of the first opening mechanism releasing a first elastic force, and the synchronization rod 38 is driven by the driving member 40 of the first synchronization device 36 to link the related components of the second synchronization device 200 to drive the locking member 204 of the second opening mechanism to no longer lock the elastic member 202 of the second opening mechanism, so that the elastic member 202 of the second opening mechanism releases a second elastic force to drive the second rail 32 of the second slide rail assembly 24 to displace in the second direction D2. According to this driving manner, the reliability that the second rail 32 of the first slide rail assembly 22 and the second rail 32 of the second slide rail assembly 24 are opened in the second direction D2 synchronously is facilitated, so as to avoid the phenomenon that the movable rail of the second slide rail assembly is driven to be opened in the opening direction relative to the movable rail of the first slide rail assembly pressed by the force of the user as in the prior art; alternatively, the driving method provided by the embodiment of the invention can also prevent the unexpected noise phenomenon generated when the movable rail of the first slide rail assembly is pressed by the force applied by the user and the elastic element of the second slide rail assembly is interlocked to release the elastic force for driving the movable rail of the second slide rail assembly, as in the prior art.
b. The synchronization devices 36, 200 are designed to be detachable, so that users can add them according to their needs.
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.
