Description

Technical Field

[0001] The present invention relates to a slide rail mechanism, in particular to a rebound slide rail structure which can be opened in a push-to-pop-up manner and can prevent over-force unlocking. Background Art

[0002] In order to prevent the closed drawer from automatically sliding open due to the vibration of the cabinet in which it is installed, some people have developed a drawer mechanism with an elastic push-button switch, such as Chinese patent CN105188478B. The main method is to install a driving device between the cabinet and the drawer, wherein the driving device has a base plate fixed to the cabinet, the base plate is recessed with a ring-shaped track, and a locking member is pivotally mounted on a thrust accumulator connected to the drawer, and the pin of the locking member is slidably moved in the track, the track having an extrusion switch section and a locking section, and the extrusion switch section has a groove edge. When the door is to be closed, when the drawer is pushed until the drawer door panel abuts the cabinet, the thrust accumulator will first drive the pin of the locking member to slow down from the contact with the groove edge and then move towards the locking section, and then drive the locking member to be engaged with the locking section, while the drawer is partially withdrawn from the cabinet and positioned in the closed position, at which time the door panel will be separated from the cabinet by a door gap. When the door is to be opened, the drawer located in the closed position is pushed further until the door panel hits the cabinet body and the user releases the door panel. The locking member is driven to disengage from the locking section, and the thrust accumulator drives the drawer to slide open.

[0003] However, the above design has many disadvantages. When the drawer is in the closed position, the size of the door gap between the door panel and the cabinet body can determine the distance from the drawer in the closed position to the door panel contacting the cabinet body, and then the door panel rebounds in the opening direction to the closed position. It is also equivalent to the optimal distance for the locking member to move to the locking section after contacting the groove edge of the extrusion switch section and slowing down. In the case that the distance between the extrusion switch section and the locking section is fixed and cannot be changed in structure, when the drawer is in the closed position, if the door gap between the door panel and the cabinet body is too large, it is equivalent to lengthening the distance between the locking member and the locking section. If the drawer is pushed too hard when closing, the drawer and its internal load have a large common inertia, which will cause the pin of the locking member traveling in the track to be affected by the groove edge of the extrusion switch section. BCPI-230472 Page 2 / 10

[0004] The impact force is too great, causing it to break or deform. When the drawer is in the closed position, the gap between the door panel and the cabinet body is too small. If the drawer is pushed closed with too much force, the pin of the locking member running in the track cannot contact the groove edge of the extrusion switch section, resulting in no deceleration function. Summary of the Invention

[0005] An object of the present invention is to provide a rebound slide rail structure that can overcome at least one disadvantage of the background art and can prevent over-force unlocking.

[0006] The rebound slide rail structure of the present invention, which can prevent excessive force from unlocking, is suitable for installation in a slide rail mechanism, wherein the slide rail mechanism has a fixed rail unit and a movable rail unit that slides back and forth along the fixed rail unit in a closing direction and an opening direction different from the closing direction. The rebound slide rail structure is arranged between the fixed rail unit and the movable rail unit, and includes a base arranged on the fixed rail unit, a slider that can move relative to the base and has a push section, a pusher connected to the movable rail unit and used to push the push section of the slider to move in the closing direction, a reverse buckle that is swingably pivoted between the slider and the base and has a push surface and a protruding pin section, a reverse buckle channel arranged between the slider and the base for the protruding pin section to move relative to each other, an elastic resistance member arranged between the slider and the base, and an elastic mechanism for accumulating a restoring elastic force to move the slider in the opening direction. The reverse buckle channel has a buckling area. The elastic resistance member corresponds to the buckling area.

[0007] When the movable rail unit moves to the closed position, the convex pin section of the reverse fastener is located in the locking area and contacts the elastic blocking member at the same time, and the pushed surface reversely blocks the pushing member, preventing the movable rail unit from moving in the opening direction. When the movable rail unit wants to move in the opening direction to the closed position, the pushing member is subjected to excessive external force and hits the pushed surface by the same external force, causing the reverse fastener to swing and causing the convex pin section to push the elastic blocking member. The elastic blocking member will buffer the excessive external force and cause the reverse fastener to rotate and reset, causing the pushing member that was separated from the pushed section due to excessive force to re-engage the pushed section, allowing the movable rail unit to return to the closed position.

[0008] The rebound slide rail structure of the present invention that can prevent unlocking by excessive force has a base with a U-shaped slit hollowed out around the periphery of the elastic blocking member. The elastic blocking member is arranged on a side edge of the buckling area and has a connecting end connected to the base, and a free end opposite to the connecting end and separated from the base.

[0009] The rebound slide rail structure of the present invention that can prevent unlocking due to excessive force has two slits that are spaced apart and hollowed out on both sides of the elastic blocking member. The elastic blocking member is arranged on one side edge of the buckling area and has two opposite connection ends that are respectively connected to the base.

[0010] The rebound slide rail structure of the present invention that can prevent unlocking due to excessive force, the reverse lock channel is arranged on the base, and also has a guide area for the protruding pin section to enter, and a turning area extending obliquely from the guide area to the locking area, and the turning area causes the reverse lock member to rotate relative to the direction of the pushing member.

[0011] The rebound slide rail structure of the present invention that can prevent unlocking due to excessive force, the counter-fastener also has a swing arm section for setting the protruding pin section, a protruding hook section that protrudes outward from one side of the swing arm section and is set at an angle to the swing arm section, and a convex shaft section that is connected to the swing arm section and is pivotally set on the slider, and the pushed surface is an arc surface and is set at the angle between the swing arm section and the protruding hook section.

[0012] The rebound slide rail structure of the present invention can prevent unlocking due to excessive force, and the rebound slide rail structure also includes a locking member and a locking circuit. The locking member has a latch section, and the locking circuit is arranged between the slider and the base. The locking circuit has an energy storage channel for relative movement of the latch section, an energy release channel, a locking position arranged between the energy storage channel and the energy release channel, an energy storage starting point arranged between the energy storage channel and the energy release channel and away from the locking position, an energy storage end point located at one end of the energy storage channel and connected to the locking position, and an energy release starting point located at one end of the energy release channel and connected to the locking position.

[0013] The rebound slide rail structure of the present invention that can prevent unlocking by excessive force, the elastic mechanism has at least one reset member. When the reset member accumulates elastic force and the pin segment is in the locked position, the pin segment is moved to the energy release starting point by the external force. When the external force disappears, the elastic mechanism immediately releases the restoring elastic force, causing the pin segment to move in the energy release channel and to the energy storage starting point.

[0014] The beneficial effect of the present invention is that: through the design of the elastic stopper, when the elastic stopper is pushed by the protruding pin section, it will buffer the excessive force of the external force and make the counter-fastener rotate and reset, thus preventing the component from being broken and damaged.

[0035] Before the present invention is described in detail, it should be noted that similar elements are denoted by the same reference numerals in the following description.

[0036] See Figure 1 、 Figure 2 and Figure 3 The present invention can prevent the rebound slide structure from being unlocked by excessive force. It is applied to a cabinet 1. However, the cabinet 1 is not limited to this and can also be applied to other sliding furniture. The cabinet 1 includes a cabinet body 11, a drawer 12, and two slide rail mechanisms 13 spaced apart and installed between the cabinet body 11 and the drawer 12. The drawer 12 has a door panel 121 located on the front side. The slide rail mechanism 13 can be used to guide the drawer 12 relative to the cabinet body 11. Figure 1 The cabinet 11 is extended forward as shown in (A) and the like. Figure 1 The drawer 12 is configured to slide horizontally back and forth between the closed position (E) of the cabinet 11 and the retracted position. Each of the slide rail mechanisms 13 comprises a fixed rail unit 131 fixedly mounted on the inner side of the cabinet 11 and a movable rail unit 132 fixedly mounted on the outer side of the drawer 12. The movable rail unit 132 can slide back and forth along the fixed rail unit 131 between a closing direction 14 and an opening direction 15 different from the closing direction 14.

[0037] See Figures 3 to 7 The first embodiment of the rebound slide rail structure of the present invention that can prevent excessive force unlocking is suitable for installation between the corresponding fixed rail unit 131 and the movable rail unit 132, and includes a base 2, a slider 3, a pusher 16, a reverse lock member 4, a reverse lock channel 5, an elastic block 6, a locking member 7, a locking loop 8, and an elastic mechanism 9.

[0038] The base 2 is mounted on the fixed rail unit 131 and includes a base wall 21 extending longitudinally from front to back, and two side walls 22 extending downward from the left and right sides of the base wall 21. The base 2 of this first embodiment also includes a slot 23 formed in the base wall 21 and opening forward.

[0039] The slider 3 is located below the base wall 21 of the base 2 and can slide forward and backward relative to the base 2. The slider 3 has a block 31 extending longitudinally forward and backward, and a push section 32 protruding outward from one side of the block 31. The block 31 has a receiving groove 33 that is recessed downward from the top surface and opens outward. The receiving groove 33 is provided in front of the push section 32.

[0040] The pushing member 16 is connected to the moving rail unit 132 and protrudes toward the slider 3 . The pushing member 16 is located in front of the pushed section 32 of the slider 3 and can be used to push the pushed section 32 to move along the closing direction 14 .

[0041] The reverse lock member 4 is pivotally mounted between the slider 3 and the base 2, allowing for swinging relative to the base 2. In this first embodiment, the reverse lock member 4 is pivotally mounted on the slider 3 and can swing relative to the base 2. However, in practice, the reverse lock member 4 can be positioned in a different location, such as being pivotally mounted on the base 2. The reverse lock member 4 includes a swing arm section 41 that is retractable within the receiving slot 33 of the slider 3; a hook section 42 that protrudes outward from a front end of the swing arm section 41 and is positioned at an angle to the swing arm section 41; a circular arc-shaped thrust surface 43 disposed at the angle between the swing arm section 41 and the hook section 42; a protruding shaft section 44 that protrudes downward from the rear side of the swing arm section 41 and is pivotally mounted to the block 31 of the slider 3; and a pin section 45 that protrudes upward from the front side of the swing arm section 41. As the slider 3 moves to different positions, the reverse lock member 4 will swing around the protruding shaft section 44.

[0042] The reverse locking channel 5 is disposed between the slider 3 and the base 2. In the first embodiment, the reverse locking channel 5 is recessed into the bottom surface of the base wall 21 of the base 2. However, the location of the reverse locking channel 5 can be changed in practice. For example, when the reverse locking member 4 is pivotally mounted on the base 2, the reverse locking channel 5 is disposed on the slider 3. The reverse locking channel 5 allows the protruding pin segment 45 to extend therein for relative movement. The reverse locking channel 5 comprises a guide area 51 located at the front side for the protruding pin segment 45 to enter, a deflection area 52 extending obliquely rearward from the rear end of the guide area 51 and used to rotate the reverse locking member 4 relative to the pusher 16, and a locking area 53 extending laterally rearward from the rear end of the deflection area 52 and communicating with the slit 23.

[0043] The elastic stopper 6 is disposed between the slider 3 and the base 2. In this first embodiment, the elastic stopper 6 is disposed on the base wall 21 of the base 2. However, the location can be varied. For example, if the reverse locking member 4 is pivotally mounted on the base 2, the elastic stopper 6 and the slit 23 are disposed on the slider 3. In this first embodiment, the elastic stopper 6 is located on a side edge of the locking region 53, and the periphery of the elastic stopper 6 is surrounded by the slit 23, providing flexibility. The elastic stopper 6 has a connecting end 61 connected to the base 2 and a free end 62, opposite the connecting end 61 and separate from the base 2.

[0044] The locking member 7 is swingably disposed between the slider 3 and the base 2. In the first embodiment, the locking member 7 is disposed on the base 2 and can pivot relative to the base 2. However, the location of the locking member 7 may be changed, for example, on the slider 3. The locking member 7 includes a swinging segment 71 located on the bottom side of the base wall 21, a pivoting segment 72 pivotally mounted upwardly from the swinging segment 71 to the base wall 21, and a latching segment 73 protruding downwardly from the swinging segment 71.

[0045] The locking loop 8 is disposed between the slider 3 and the base 2. In the first embodiment, the locking loop 8 is recessed into the top surface of the slider 3. However, the location of the locking loop 8 can be changed in practice. For example, when the locking member 7 is pivotally mounted on the slider 3, the locking loop 8 is disposed on the base 2. The locking loop 8 allows the latch section 73 to extend therein for relative movement. The locking loop 8 comprises an energy storage channel 81 and an energy release channel 82 arranged in parallel and spaced apart relation to each other. A locking position 83 disposed between the energy storage channel 81 and the energy release channel 82 and near the front end thereof, an energy storage starting point 84 disposed between the energy storage channel 81 and the energy release channel 82 and near the rear end thereof and away from the locking position 83, an energy storage end point 85 located at one end of the energy storage channel 81 and connected to the locking position 83, and an energy release starting point 86 located at one end of the energy release channel 82 and connected to the locking position 83.

[0046] The elastic mechanism 9 includes two return members 91 connected in parallel between the front end of the slider 3 and the fixed rail unit 131. The elastic mechanism 9 is used to accumulate a restoring force to move the slider 3 in the opening direction 15, thereby providing a restoring force for the latch section 73 to move relative to the energy release channel 82 from the energy release starting point 86 to the energy storage starting point 84. The return members 91 of this first embodiment are tension springs, but their construction and placement are not limited to this. It should be noted that the number of return members 91 is not limited to two and can be one, three, etc., depending on actual needs.

[0047] See Figure 1 、 Figure 2 The following describes the process of guiding the drawer 12 to move between the open position and the closed position relative to the cabinet body 11 with respect to the rebound slide rail structure of the present invention that can prevent excessive unlocking.

[0048] See Figure 1 、 Figure 6 、 Figure 7 , when the drawer 12 is located Figure 1 When in the open position shown in (A), the slider 3 extends forward from the base 2, and the pushing member 16 is spaced in front of the pushed section 32, the protruding hook section 42 of the counter-fastener 4 is located in the receiving groove 33, and the protruding pin section 45 is located in front of the guide area 51, and at the same time, the locking pin section 73 is relatively moved to the energy storage starting point 84.

[0049] See Figure 1 、 Figure 8 、 Figure 9 When the drawer 12 is to be closed, the drawer 12 is pushed by an external force, and the drawer 12 is driven as follows Figure 1As shown in (B) in the figure, the slider 3 moves backward in the closing direction 14, first driving the pushing member 16 to move backward to contact the pushed section 32, but the slider 3 has not yet been pushed. At this time, the reverse lock member 4 does not rotate, the locking section 73 remains at the energy storage starting point 84, and the elastic mechanism 9 is not stretched.

[0050] See Figure 1 、 Figure 10 、 Figure 11 , when the drawer 12 is as Figure 1 As shown in (C), the slider 3 continues to move backward in the closing direction 14, driving the pusher 16 to push the pushed section 32 backward, causing the slider 3 to also move backward relative to the base 2. At this point, the protruding pin section 45 of the reverse retaining member 4 moves to the turning area 52, causing the reverse retaining member 4 to rotate about the protruding shaft section 44, allowing the protruding hook section 42 to extend outward from the receiving groove 33. This also causes the latch section 73 to move relative to the energy storage starting point 84 along the energy storage channel 81 toward the energy storage end point 85. Simultaneously, the elastic mechanism 9 is stretched, gradually accumulating a restoring force.

[0051] See Figure 1 、 Figure 12 、 Figure 13 , when the drawer 12 is as Figure 1 As shown in (D) in FIG, the door panel 121 continues to be pushed backward until it abuts the cabinet body 11, which in turn drives the pusher 16 to push the pushed section 32 backward, causing the slider 3 to retract relatively backward into the base 2. At this point, the protruding pin section 45 of the reverse catch 4 moves to the locking area 53, and the reverse catch 4 rotates around the protruding shaft section 44 until the protruding hook section 42 extends outward from the receiving groove 33, allowing the pushed surface 43 to reversely engage the pusher 16. The detent section 73 moves relative to the energy storage end point 85, and the elastic mechanism 9 is simultaneously stretched to its maximum length.

[0052] See Figure 1 、 Figure 14 、 Figure 15 Then, when the drawer 12 is released and the external force disappears, the elastic mechanism 9 releases the restoring elastic force to drive the slider 3 to move toward the opening direction 15 until the latch section 73 moves relatively to the locking position 83 and is locked in position, allowing the drawer 12 to be opened as shown in FIG. Figure 1As shown in (E) in FIG, the door panel 121 is slightly retracted forward to the closed position, so that a door gap 17 is formed between the door panel 121 and the cabinet body 11, and the width of the door gap 17 is X. At this time, the pushed section 32 will push the pusher 16 to move forward, but because the protruding pin section 45 is still in the locking area 53 and contacts the elastic blocking member 6, the reverse locking member 4 also moves forward without rotating, and the pushed surface 43 is still locked against the pusher 16, preventing the moving rail unit 132 (see FIG. Figure 3 ) moves in the opening direction 15, and the elastic mechanism 9 also accumulates and retains sufficient restoring elastic force to drive the slider 3 to slide forward.

[0053] See Figure 1 、 Figure 16 、 Figure 17 It should be noted that during the above closing process, if the user pushes the drawer 12 to close with an external force exceeding the normal use force, the drawer 12 will not be Figure 1 As shown in (F) in FIG, the door gap 17 is moved forward beyond the closed position, and the width of the door gap 17 is increased from X to Y and becomes too wide to become X+Y, that is, when the movable rail unit 132 (see FIG. Figure 3 ) when it is intended to move in the opening direction 15 to the closed position, the push member 16 is subjected to the overforce by the same external force and moves forward from the pushed section 32 by a distance Y and hits the pushed surface 43. The reverse catch 4 will then swing around the convex shaft section 44 to cause the convex pin section 45 to push the elastic stop member 6, causing the elastic stop member 6 to bend and deform and accumulate elastic force. Then, the elastic stop member 6 will rebound to buffer and eliminate the overforce and allow the reverse catch 4 to rotate and return to its original position, causing the push member 16, which was separated from the pushed section 32 due to the overforce, to be pushed back to engage with the pushed section 32 again to restore to the state as shown in FIG. Figure 15 At the same time, the pushed section 32 is not pushed and the slider 3 does not move, and the bayonet section 73 is still in the locked position 83 and is not damaged by impact.

[0054] See Figure 1 、 Figure 15 、 Figure 7 When the drawer 12 is to be opened, the door panel 121 is pressed again to open the drawer 12. Figure 1 The closed position of (E) is moved back to Figure 1 When the door panel 121 in (D) abuts against the cabinet body 11, the latch section 73 will also move from the locked position 83 to the energy release starting point 86. When the user lets go, the elastic mechanism 9 immediately releases the restoring elastic force, causing the latch section 73 to move along the energy release channel 82 and to move to the energy storage starting point 84. The drawer 12 will then pop out and move back. Figure 1 The open position shown in (A) in FIG.

[0055] See Figure 18 The second embodiment of the rebound slide rail structure that can prevent over-force unlocking of the present invention is substantially the same in structure as the first embodiment, except that the design of the elastic stopper 6 is different. The base 2 of the second embodiment has two slits 23 that are spaced apart and hollowed out on both sides of the elastic stopper 6. The elastic stopper 6 has two opposite connection ends 61 that are respectively connected to the base 2. Figure 19 As shown, when the elastic stop member 6 is pushed by the protruding pin section 45, it can also bend and buffer to eliminate the excessive external force.

[0056] In summary, the rebound slide rail structure of the present invention can prevent unlocking due to excessive force. Through the design of the elastic stop member 6, when pushed by the protruding pin section 45, the elastic stop member 6 will buffer the excessive force of the external force and cause the counter-fastener 4 to rotate and reset, thereby preventing the component from breaking or deforming due to excessive impact force. Therefore, the rebound slide rail structure of the present invention can prevent unlocking due to excessive force and can indeed improve the shortcomings of the existing technology. It has a simple structure and is convenient and practical, so it can indeed achieve the purpose of the present invention.

[0057] The above descriptions are merely embodiments of the present invention and should not be used to limit the scope of the present invention. In other words, any simple equivalent changes and modifications made according to the claims and description of the present invention still fall within the scope of the present invention.

The rebound slide rail structure capable of preventing over-force unlocking according to claim 1, characterized in that: The rebound slide rail structure also includes a locking piece and a locking circuit, wherein the locking piece has a latch section, and the locking circuit is arranged between the slider and the base, and the locking circuit has an energy storage channel for the latch section to move relative to each other, an energy release channel, a locking position arranged between the energy storage channel and the energy release channel, an energy storage starting point arranged between the energy storage channel and the energy release channel and away from the locking position, an energy storage end point located at one end of the energy storage channel and connected to the locking position, and an energy release starting point located at one end of the energy release channel and connected to the locking position.

7. The rebound slide rail structure capable of preventing over-force unlocking according to claim 6, characterized in that: The elastic mechanism has at least one reset member. When the reset member accumulates elastic force and the latch segment is in the locked position, the latch segment is moved to the energy release starting point by the external force. When the external force disappears, the elastic mechanism immediately releases the restoring elastic force, causing the latch segment to move in the energy release channel and to the energy storage starting point.
