Description

Connecting mechanism with buffering function and sliding rail assembly

Technical Field

The present invention relates to a mechanism and a slide rail, and more particularly, to a connecting mechanism and a slide rail assembly with a buffering function.

Background

Generally, bottom-mounted drawer slide assemblies (underslung slide rail assemblies) are typically mounted at the bottom of a drawer as a concealed slide assembly. The bottom-mounted track assembly generally includes a first track and a second track that are displaceable relative to the first track. The first rail is mounted on a cabinet body, and the second rail is used for bearing or supporting the drawer, so that the drawer can be easily pulled out of or pushed into the cabinet body relative to the first rail through the second rail to be folded. When the drawer is pulled out from the cabinet body, the bottom-mounted drawer slide rail assembly is kept hidden at the bottom of the drawer.

U.S. patent publication No. US 8,424,984B 2 discloses a device for releasably connecting a drawer to a slide. This patent discloses that when the drawer is in a mounting environment (mounting condition), a stop of the device can contact the mating retaining portion of the slide rail through a region of flexible material, so that the region acts as a cushioning (shock) feature. This patent is incorporated herein by reference. However, this case requires an extra installation of such a very small component to achieve the so-called shock absorbing (cushien) function, and in case of losing the component, the shock absorbing function is lost.

Detailed Description

As shown in fig. 1 and 2, a piece of furniture 20 includes a first furniture piece 22 and at least a second furniture piece (also referred to as furniture pieces). Here, two second furniture parts 24a, 24b are taken as an example. Each second furniture part, for example the second furniture part 24a, is displaceable relative to the first furniture part 22. Preferably, the second furniture member 24a is readily displaceable relative to the first furniture member 22 via a pair of slide assemblies 26. The first furniture member 22 may be a cabinet, and the second furniture members 24a, 24b may be drawers, but the implementation is not limited thereto. The pair of track assemblies 26 provide for the second furniture member 24a to be movably mounted to the first furniture member 22. Each slide rail assembly 26 is mounted on the bottom of the second furniture member 24a to form a so-called bottom-mount (underslung) slide rail assembly. The slide assembly 26 includes a first rail 28 and a second rail (or simply slide) 30 longitudinally displaceable relative to the first rail 28, and preferably further includes a third rail 32 movably mounted between the first rail 28 and the second rail 30 for extending a displacement stroke of the second rail 30 relative to the first rail 28. Wherein the first rail 28 is fixedly mounted to the first furniture member 22, and the second rail 30 is used to carry the second furniture member 24a, as shown in fig. 1, so that the second furniture member 24a can be easily moved from the inside of the first furniture member 22 to the outside of the first furniture member 22 through the second rail 30; alternatively, the second furniture member 24a can be easily pushed from outside the first furniture member 22 into the first furniture member 22.

As shown in fig. 3 and 4, the slide assembly 26 includes a connecting mechanism 34 located adjacent to the second rail 30. Here, it is exemplified that the second rail 30 has a front portion 36a and a rear portion 36b, and the connecting mechanism 34 is mounted to the front portion 36a of the adjacent second rail 30.

As shown in fig. 5, 6 and 7, the second rail 30 is disposed longitudinally and includes a first side wall 38a, a second side wall 38b and a supporting portion 40 located between the first side wall 38a and the second side wall 38 b. The first sidewall 38a, the second sidewall 38b and the supporting portion 40 together define a supporting space 42. Preferably, the second rail 30 further includes a first extension segment 44a and a second extension segment 44b respectively substantially vertically connecting the first side wall 38a and the second side wall 38b, and the first extension segment 44a and the second extension segment 44b are located adjacent to the supporting space 42.

The connecting mechanism 34 includes a base 82 and a cushioning structure 92. Preferably, the buffer structure 92 is disposed on the base 82.

The base 82 is detachably fixed to the second rail 30, such that the base 82 directly contacts the second rail 30, and the buffer structure 92 indirectly contacts the second rail 30 through the base 82. Preferably, the base 82 is made of a flexible material (e.g., plastic). The base 82 is fixedly mounted adjacent the front portion 36a of the second rail 30. Preferably, the base 82 includes a main body 88, an elastic portion 90 and the buffer structure 92. The main body 88 is mounted to the supporting space 42 of the second rail 30, and preferably, the first extension 44a and the second extension 44b of the second rail 30 can provide the main body 88 for supporting. The elastic portion 90 is connected to and located at a side of the main body portion 88, and the elastic portion 90 can extend out of the supporting space 42 from a gap 94 of the second rail 30. The cushioning structure 92 is connected to and located on the front side of the main body portion 88.

Preferably, the connecting mechanism 34 further includes a support member 84 and a height adjustment member 86. Wherein the base 82, the supporting member 84 and the height adjusting member 86 form a height adjusting device 48.

The support 84 is movably mounted to the base 82. The support 84 includes a support portion 106, and preferably also includes a first guide feature 108 (also referred to as a guide feature), a first thread structure 110, and a stop portion 112. Preferably, the supporting portion 106, the first guiding feature 108, the first thread structure 110 and the stopping portion 112 are integrally formed, and the first guiding feature 108 and the stopping portion 112 are located at the bottom of the supporting portion 106. The stop portion 112 is located between the first guiding feature 108 and the first thread structure 110, and the stop portion 112 corresponds to a position-limiting section 114 of the base 82. Preferably, the second rail 30 and/or the base 82 has a second guide feature 116 (also referred to simply as a guide feature) corresponding to the first guide feature 108 of the support member 84, and the guide features 108, 116 are an inclined surface or an arc surface. Preferably, the supporting portion 40 of the second rail 30 has an upper notch 118 communicating with the supporting space 42. When the main body portion 88 of the base 82 is mounted to the supporting space 42 of the second rail 30, the supporting portion 106 of the supporting member 84 is located in the upper notch 118.

The height adjustment member 86 is used for adjusting the displacement of the supporting member 84 relative to the base 82. The height adjustment member 86 is rotatably mounted to one of the base 82 and the support member 84. Here, the height adjuster 86 is rotatably mounted to the base 82. For example, the base 82 has a shaft portion 120 disposed generally longitudinally for mounting the height adjustment member 86. The height adjustment member 86 includes a second threaded structure 122. The second thread structure 122 corresponds to the first thread structure 110 of the support member 84. Here, the first thread structure 110 and the second thread structure 122 are substantially longitudinally arranged.

Preferably, the connecting mechanism 34 further includes a lateral adjustment device 46. The lateral adjustment device 46 includes a first base 50, a second base 52 and a lateral adjustment member 54. Wherein the lateral adjustment device 46 is pre-mounted on the second furniture piece 24 a.

The first base 50 is removably snapped with the base 82 to attach to the second rail 30, such as to adjacent the front portion 36a of the second rail 30. Preferably, the first base 50 includes a main body 56, a mounting space 58 and a mounting portion 60. Wherein the mounting space 58 is located at the body portion 56; the mounting portion 60 is located at one side of the main body portion 56, and the mounting portion 60 is, for example, a hook capable of detachably hooking on the first side wall 38a of the second rail 30. Preferably, the first base 50 includes a latching structure 96, and the elastic portion 90 of the base 82 is detachably latched with the latching structure 96 of the first base 50. Specifically, the elastic portion 90 has at least one first engaging section 98, and the engaging structure 96 has at least one second engaging section 100 corresponding to the first engaging section 98. Preferably, the at least one first latching section 98 and the at least one second latching section 100 have a plurality of saw-tooth profiles. Preferably, the base 82 further has an operating portion 102 extending from the elastic portion 90, the operating portion 102 is used for an operator to conveniently press the elastic portion 90, so that the first latching section 98 of the elastic portion 90 and the second latching section 100 of the first base 50 can be disengaged from each other. Alternatively, by operating the operating portion 102, the first engaging section 98 is retracted into the supporting space 42, so that the base 82 can be detached from the second rail 30.

The second base 52 is displaceable relative to the first base 50. Preferably, the first base 50 includes at least one first feature 62; the second base 52 includes at least one second feature 64. Wherein the first feature 62 and the second feature 64 cooperate to allow the second base 52 to be linearly displaced relative to the first base 50 within a limited range. For example, the first feature 62 includes two protrusions 63a, 63b of different shapes; on the other hand, the second feature 64 includes two sub-features corresponding to the two protrusions 63a, 63b of the first feature 62, for example, the second feature 64 includes two receiving spaces 65a, 65b for receiving the two protrusions 63a, 63b, respectively. The two receiving spaces 65a, 65b are, for example, a long hole or a long slot, and the long hole or the long slot is disposed substantially transversely and has a length or a dimension slightly larger than the two protruding portions 63a, 63b of the first feature 62, so that the second base 52 can be linearly displaced relative to the first base 50 within a limited range through the two protruding portions 63a, 63b and the two receiving spaces 65a, 65 b. It is noted that the structural features of the first feature 62 and the second feature 64 are interchangeable and are not limited in implementation. That is, the first base 50 and the second base 52 are movably connected to each other. In addition, one of the first base 50 and the second base 52 includes at least one guiding structure 70 (as shown in fig. 7), and the guiding structure 70 also helps to guide the displacement direction of the second base 52 relative to the first base 50. Here, it is taken as an example that the second base 52 includes two pairs of guiding structures 70, and the guiding structures 70 are, for example, bumps for keeping the positions of two corresponding edges 72a and 72b (e.g., front edge and rear edge) of the first base 50. Preferably, the second base 52 includes a contact portion 104, and the contact portion 104 corresponds to the buffer structure 92. When the second furniture piece 24a is mounted to the second rail 30, the second furniture piece 24a can be pre-abutted against the buffer structure 92 through the contact portion 104 of the second base 52, thereby compensating for a possible longitudinal gap K between the first base 50 relative to the second rail 30. The contact portion 104 and the buffer structure 92 are interchangeable, that is, the second base 52 has the buffer structure 92, and the base 82 has the contact portion 104, which is not limited in implementation.

The lateral adjustment member 54 is used for adjusting the longitudinal length of the second base 52 relative to the second rail 30 to displace in a lateral (or transverse) direction. The lateral adjustment member 54 is rotatably mounted on one of the first base 50 and the second base 52. Herein, the lateral adjustment member 54 is rotatably mounted on the second base 52. For example, the second base 52 has a shaft 74, and the lateral adjustment member 54 is rotatably mounted on the second base 52 through the shaft 74. Preferably, the lateral adjustment member 54 is received in the mounting space 58 of the first base 50, and a portion of the lateral adjustment member 54 is exposed out of an opening 76 of the second base 52 to facilitate the rotation of the lateral adjustment member 54 by an operator. Preferably, the lateral adjustment member 54 includes an adjustment portion 78; and one of the first base 50 and the second base 52 is configured with a transmission structure 80 (as shown in fig. 5). Here, the first base 50 is configured with the transmission structure 80 as an example. The transmission structure 80 is used to cooperate with the adjusting portion 78. Preferably, the adjustment portion 78 is substantially spirally configured.

As shown in fig. 8, 9 and 10, the supporting portion 106 of the supporting member 84 is located at a position substantially lower than or equal to the height of the supporting portion 40 of the second rail 30. The operator can adjust the height adjustment member 86 to rotate relative to the base 82 in a first operation direction a1, such that the second thread structure 122 of the height adjustment member 86 and the first thread structure 110 of the support member 84 can cooperate with each other to displace the support member 84 relative to the base 82, and the support portion 106 of the support member 84 can ascend from one position to another position through the first guide feature 108 and/or the second guide feature 116, so as to adjust a height of the support portion 106 of the support member 84 relative to the supporting portion 40 of the second rail 30.

As shown in fig. 9 and 11, when the operator adjusts the height adjustment member 86 to rotate in the first operating direction a1, the supporting member 84 is displaced relative to the base 82 and/or the second rail 30 in a first longitudinal direction L1. When the supporting member 84 is displaced to a predetermined distance along the first longitudinal direction L1, the stopping portion 112 of the supporting member 84 is stopped by the stopping portion 114 of the base 82, so as to prevent the supporting member 84 from being excessively displaced along the first longitudinal direction L1.

It should be noted that the operator can adjust the height adjustment member 86 to rotate in a second operation direction (e.g., opposite to the first operation direction a1) to displace the supporting member 84 in a second longitudinal direction (e.g., opposite to the first longitudinal direction L1) so as to adjust the height of the supporting portion 106 of the supporting member 84 relative to the supporting portion 40 of the second rail 30.

As shown in fig. 12 and 13, when the second furniture piece 24a is mounted to the second rail 30, the bearing portion 40 of the second rail 30 can be used for bearing or supporting the second furniture piece 24 a. The support portion 106 of the support member 84, on the other hand, faces the second furniture member 24 a. By adjusting the height adjusting member 86 (e.g. rotating in the first operating direction a1), the supporting portion 106 of the supporting member 84 can raise the height H of the supporting portion 106 of the supporting member 84 relative to the supporting portion 40 of the second rail 30 by means of the first guiding feature 108 and/or the second guiding feature 116, that is, the supporting member 84 can change the height H of the second furniture member 24a relative to the supporting portion 40 of the second rail 30 by means of the guiding feature (108 or 116) to adjust the front height of the second furniture member 24a relative to the first furniture member 22, so as to correct the front mounting error of the second furniture member 24a relative to the first furniture member 22.

As shown in fig. 14, the second base 52 can be fixedly connected (e.g., by screwing) to the second furniture member 24a via at least one fixing portion 61 for mounting the second furniture member 24a to the second rail 30. Wherein the bearing portion 40 of the second rail 30 can be used for bearing the second furniture piece 24 a. Wherein a first gap G1 is formed between the side 124 of the second furniture member 24a and the first furniture member 22. On the other hand, the adjusting portion 78 of the lateral adjusting member 54 and the transmission structure 80 can cooperate with each other. Wherein, the adjusting part 78 can be a spiral guiding groove or guiding slot; on the other hand, the transmission structure 80 can be a protrusion located in the guiding groove or the guiding groove, and when the lateral adjustment member 54 is adjusted, the transmission structure 80 can abut against one of two side walls of the guiding groove or the guiding groove.

Referring to fig. 15, when the lateral displacement of the second furniture member 24a is to be adjusted, the operator can adjust the lateral adjustment member 54 to displace the second base 52 relative to the first base 50, so as to change a lateral position of the second furniture member 24a relative to the first furniture member 22 or the second rail 30. For example, the operator can adjust the lateral adjustment member 54 to rotate in a first rotation direction R1, such that the adjustment portion 78 of the lateral adjustment member 54 and the transmission structure 80 can cooperate with each other, such that the second base 52 can be displaced in a first lateral direction D1 relative to the second rail 30 or the first base 50, such that the second furniture member 24a reaches a second lateral position P2 from a first lateral position P1 (as shown in fig. 14) relative to the second rail 30. In this manner, the first spacing G1 between the side 124 of the second furniture member 24a and the first furniture member 22 is changed to a second spacing G2. Wherein the second distance G2 is greater than the first distance G1.

As shown in fig. 16, when the second furniture member 24a is adjusted to laterally displace relative to the first furniture member 22, the operator can also adjust the lateral adjustment member 54 to rotate in a second rotation direction R2, so that the adjustment portion 78 of the lateral adjustment member 54 and the transmission structure 80 can cooperate with each other, and the second base 52 can displace relative to the second rail 30 or the first base 50 in a second lateral direction D2 (opposite to the first lateral direction D1), so that the second furniture member 24a can reach a third lateral position P3 from the second lateral position P2 relative to the second rail 30. In this manner, the second spacing G2 is changed from the second spacing G3 between the side 124 of the second furniture member 24a and the first furniture member 22. Wherein the third gap G3 is smaller than the first gap G1.

Therefore, the transmission structure 80 can be used to convert a rotational movement of the lateral adjustment member 54 (or the adjustment portion 78) into a linear or lateral displacement of the second base 52 relative to the second rail 30 or the first base 50.

As shown in fig. 17, the carrying portion 40 of the second rail 30 can be used to carry or support the bottom of the second furniture piece 24 a. Further, the bumper structure 92 is mounted to the front portion 36a of the adjacent second rail 30 through the main body portion 88 of the base 82, i.e., the bumper structure 92 does not directly contact the second rail 30. Preferably, the buffer structure 92 includes at least one serpentine profile 126. Here, the serpentine profile 126 is generally composed of at least one U-shaped section or V-shaped section. On the other hand, the second base 52 is fixedly connected to the second furniture piece 24a in advance, and therefore, the second base 52 can be regarded as a part of the second furniture piece 24 a. The position of the contact portion 104 of the second base 52 corresponds to the buffer structure 92. Wherein the buffer structure 92 has a predetermined longitudinal length X1.

As shown in fig. 18, when the second furniture element 24a is mounted to the second rail 30, there are some cases where there is inevitably a gap of a mounting tolerance between the second furniture element 24a and the second rail 30, and therefore, there is a possibility that the second furniture element 24a and the second rail 30 are still displaced relative to each other, so that interference of collision may occur. For example, based on the clearance of the installation tolerance, the second furniture piece 24a may be displaced in a longitudinal direction (e.g., the first longitudinal direction L1) relative to the second rail 30 by an external force, during which the second furniture piece 24a can push the buffering structure 92 through the contact portion 104 of the second base 52, so that the buffering structure 92 is pressed to change from the predetermined longitudinal length X1 (as shown in fig. 17) to a pressed longitudinal length X2. Wherein the extruded longitudinal length X2 is less than the predetermined longitudinal length X1.

As shown in fig. 19 and 20, the longitudinal gap K between the second furniture piece 24a (or second base 52) relative to the second rail 30 may occur due to the mounting tolerance. Here, the longitudinal gap K is formed between the mounting portion 60 of the first base 50 and the first side wall 38a of the second rail 30 as an example.

As shown in fig. 19 and 21, when the second furniture piece 24a is displaced in the first longitudinal direction L1 relative to the second rail 30, the contact portion 104 of the second base 52 pushes the buffer structure 92 to make the mounting portion 60 of the first base 50 approach the first longitudinal direction L1 relative to the first sidewall 38a of the second rail 30, so that the longitudinal gap K (shown in fig. 20) can be shortened to a longitudinal gap K1 (shown in fig. 22). It can be seen that the buffering structure 92 can be used to compensate the longitudinal gap K that may occur between the first base 50 and the second rail 30, which helps the second furniture member 24a to be mounted on the second rail 30 without interference and with good stability.

From the above description, it can be seen that the enhanced efficacy and advantages of the present invention are:

1. the lateral adjustment device 46 can be used to adjust the lateral position of the second furniture member 24a relative to a sliding track (e.g., the second track 30) or the first furniture member 22.

2. The height adjustment device 48 can be used to adjust the height of the second furniture member 24a relative to a sliding track, such as the second track 30.

3. The lateral adjustment device 46 and the height adjustment device 48 are removably mounted to a slide rail (e.g., the second rail 30).

4. The contact portion 104 of the second base 52 abuts against the buffer structure 92 of the base 82, thereby compensating for a possible longitudinal gap K between the first base 50 and the second rail 30 when the second furniture piece 24a is mounted to the second rail 30.

5. The base 82 of the height adjusting device 48 is mounted to a slide rail (e.g., the second rail 30), and the base 82 includes a resilient portion 90, and the base 82 is detachably engaged with the first base 50.

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.
