Description

Technical Field

[0001] This utility model relates to a buffer device with a guide mechanism, specifically a drawer or cabinet adapted to furniture, which uses a first movable member to align with a second movable member, enabling a guide mechanism to quickly unfold and slowly retract. Background Technology

[0002] Existing technology, disclosed in Chinese Patent Publication No. CN2925237U, discloses a self-closing buffer device, including a base, a sliding buckle, a slider, a buffering mechanism, and a spring. The sliding buckle is pivotally connected to the slider, which is respectively disposed on the base for reciprocating movement. The buffering mechanism is disposed on the base, for example, a buffering mechanism composed of damping gears. The damping gears mesh with a gear rack of the slider. The two ends of the spring are respectively installed on the base and the sliding buckle. Through the buffering force of the damping gear, when the sliding buckle is subjected to the spring's return force, the sliding buckle, in conjunction with the slider, retracts and displaces on the base. At this time, the spring's tension is greater than the buffering force generated by the damping gear meshing with the gear rack. However, the aforementioned displacement buffering method results in a problem where, when the sliding buckle and slider unfold and displace on the base, in addition to the tension stored in the spring, there is also a buffering force generated by the damping gear meshing with the slider's gear rack. Therefore, how to solve the problem of the buffering force generated by the damping gear meshing with the gear rack when the sliding buckle and slider unfold and displace on the base is a direction that those engaged in this industry urgently want to research and improve.

[0003] Furthermore, existing damping gear-based buffer devices, such as unidirectional damping gears, are larger and more expensive than bidirectional damping gears. Therefore, addressing the issues of large size and high cost in unidirectional damping gear-based buffer devices is a key area of ​​research and improvement that industry professionals are eager to explore.

[0073] This utility model uses the displacement member 3 as one of the following: an elastic member, a hydraulic rod, or a pneumatic rod, or other components that can be reset after being stretched under force. This utility model is described using an elastic member (e.g., a tension spring) as an example. The example is not intended to limit the scope of the patent application of this utility model.

[0074] Please see Figure 3 and Figure 7As shown, when the guide part 2 of the guide mechanism GD is subjected to force and unfolds in the displacement space 10, the guide part 2 of the guide mechanism GD stretches the displacement member 3 to move in a first direction D1. The guide part 2 moves in the same direction within the displacement space 10 of the base 1 through the first guide part 21 and the second guide part 22. The hook part 211 of the first guide part 21 leaves the notch 121 of the first slide groove 12 of the displacement space 10. The fourth limiting part 2111 of the hook part 211 disengages from the first limiting groove 1211 of the notch 121. The first limiting part 214 of the first guide part 21 and the fourth limiting part 2111 of the hook part 211 abut against the first partition wall 123. The first guide part 21 is in the first... The second limiting part 215 and the third limiting part 216 abut against the second partition wall 132. The displacement member 3 is in the second sliding groove 13 of the displacement space 10. The fixing part 222 of the second guide part 22 drives one end of the displacement member 3, causing the displacement member 3 to extend and generate a pulling force. At this time, the guide part 2 of the guide mechanism GD drives the second movable member 5 to move in the first direction D1 through the plurality of guide features 20. The second movable member 5 moves from the rear end 112 of the long slot 11 to the front end 111 of the long slot 11, causing the second movable member 5 to disengage from the first movable member 4. The plurality of guide features 20 of the guide part 2 push the second movable member 5 to rotate, allowing the guide part 2 of the guide mechanism GD to quickly unfold.

[0075] Please see Figures 8 to 10 As shown, when the guide part 2 of the guide mechanism GD continues to displace and unfold until the first limiting part 214 of the first guide part 21 and the fourth limiting part 2111 of the hook part 211 disengage from the first partition wall 123, the first guide part 21 rotates upward relative to the positioning post 221 of the second guide part 22 through the positioning hole 213, so that the fourth limiting part 2111 of the hook part 211 abuts against the second limiting groove 124 of the first slide groove 12, and the relief groove 122 of the first slide groove 12 provides a stop for the bearing part 212 of the first guide part 21, and the first limiting part 214 of the first guide part 21 abuts against the relief groove 122 of the first slide groove 12.

[0076] Please see Figure 11 and Figure 12As shown, when the guide part 2 of the guide mechanism GD is subjected to force again and returns to the retracted displacement of the displacement space 10 of the base 1, the guide part 2 rotates downward relative to the positioning post 221 of the second guide part 22 through the positioning hole 213 of the first guide part 21. The fourth limiting part 2111 of the hook part 211 disengages from the second limiting groove 124 of the first slide groove 12, and the bearing part 212 of the first guide part 21 disengages from the relief groove 122 of the first slide groove 12. The first limiting part 214 disengages from the relief groove 122 of the first slide groove 12. The displacement member 3 of the guide mechanism GD, through elastic restoring force, drives the guide part 2 of the guide mechanism GD to move in a second direction D2 opposite to the first direction D1. One end of the displacement member 3 drives the second guide part 22 of the guide part 2 to reset in the second slide groove 13. One end of the displacement member 3 drives the fixing part 222 of the second guide part 22. The second guide part 22 passes through the positioning hole 213 of the first guide part 21. The positioning post 221 drives the first guide part 21 to continue moving in the second direction D2. The first limiting part 214 of the first guide part 21 and the fourth limiting part 2111 of the hook part 211 abut against the first partition wall 123 again. The first guide part 21 continues to abut against the second partition wall 132 between the second limiting part 215 and the third limiting part 216. The guide part 2 of the guide mechanism GD drives the second movable part 5 towards the second partition wall 123 through the plurality of guide features 20. In the second direction D2 displacement, the second movable member 5 is displaced from the front end 111 of the long slot 11 to the rear end 112 abutting against the long slot 11, so that the second movable member 5 is aligned and contacts the first movable member 4. When the guide part 2 pushes the second movable member 5 to rotate through the plurality of guide features 20, the second movable member 5 generates a resistance because it docks with and pushes the first movable member 4 to rotate. At this time, the pulling force of the displacement member 3 is greater than the resistance of the first movable member 4, so that the guide part 2 of the guide mechanism GD slowly retracts.

[0077] Continuing from the above, this utility model uses the first movable member 4 as a damping gear, the second movable member 5 as a gear, and the plurality of guiding features 20 as teeth. The gear meshes with the plurality of teeth, and the gear is aligned with the damping gear (e.g., a bidirectional damping gear). This is merely an illustrative example. The first movable member 4 may be a rolling bearing (not shown in the figure), the second movable member 5 may be a cam (not shown in the figure), and the plurality of guiding features 20 may be arc-shaped protrusions (not shown in the figure). The rolling bearing presses against the plurality of arc-shaped protrusions, and the rolling bearing is aligned with and presses against the cam. The first movable member 4 and the second movable member 5 may be other rotating components. This embodiment is not intended to limit the scope of this invention.

[0078] Please continue reading. Figure 3 and Figure 4 As shown, when the guide part 2 of the guide mechanism GD slowly retracts in the displacement space 10 of the base 1, until the first guide part 21 disengages from the first partition wall 123 between the first limiting part 214 and the fourth limiting part 2111 of the hook part 211, the hook part 211 of the first guide part 21 enters the notch 121 of the first slide groove 12 of the displacement space 10, the fourth limiting part 2111 of the hook part 211 abuts against the first limiting groove 1211 of the notch 121, and the first guide part 21 continuously abuts against the second partition wall 132 between the second limiting part 215 and the third limiting part 216, the side wall 131 of the second slide groove 13 is used for the fixing part 222 of the second guide part 22 to limit the displacement member 3.

[0079] Please refer to the following: Figure 3 , Figure 6 , Figure 11 and Figure 13 As shown, the preset first rail 6 is installed in the cabinet (not shown in the figure), the preset second rail 7 is installed in the drawer (not shown in the figure), the preset first rail 6 is slidably connected to the preset second rail 7, and the base 1 is installed on the preset first rail 6. A preset actuating lever 71 is provided on one side of the preset second rail 7 adjacent to the base 1. The preset actuating lever 71 is used to drive the guide mechanism GD. The guide part 2 of the guide mechanism GD is aligned with the preset actuating lever 71 through the positioning groove 217 of the first guide part 21. When the user applies force to open and close the drawer, the preset second rail 7 is displaced relative to the preset first rail 6 in the first direction D1 and the second direction D2. The preset actuating lever 71 engages with the positioning groove 217 of the first guide part 21, so that the first guide part 21 is subjected to force. Its cooperative structure or mechanism is as described above and will not be repeated here.

[0080] In this invention, the second movable member 5 is aligned with the first movable member 4. The guide mechanism GD can drive the second movable member 5 to move to abut against both ends of the elongated slot 11. Thus, when the guide mechanism GD expands and moves in the displacement space 10, the second movable member 5 disengages from the first movable member 4, allowing the guide mechanism GD to expand quickly. When the guide mechanism GD resets and moves in the opposite direction to retract, the second movable member 5 engages with and pushes the first movable member 4 to generate resistance, allowing the guide mechanism GD to retract slowly.
