slide rail assembly

Abstract

This invention relates to a slide rail assembly with a press-to-open function. The slide rail assembly includes a first rail, a second rail, a control member, an auxiliary member, a working member, and an elastic structure. When the second rail is pulled out from a retracted position relative to the first rail, the control member and the working member can come into contact with each other, causing the working member to rotate from a first state to a second state. This allows the control member to move from a locked position to a predetermined path of the auxiliary member, thereby allowing the second rail to open. The working member can return from the second state to the first state in response to the restoring elastic force of the elastic structure.

Description

Technical Field

[0001] This invention relates to a slide rail mechanism, and more particularly to a slide rail assembly with a protection mechanism for a press-to-open mechanism. Background Technology

[0002] With the advancement of industrial technology, the functions of drawer slides on the market are becoming increasingly diversified. Taking the push-open function as an example, if a drawer slide assembly has a push-open function, and a drawer is installed in a cabinet through the drawer slide assembly, when the drawer is closed into the cabinet, a push-open gap is formed between the front panel of the drawer and the cabinet. This push-open gap allows the user to press the drawer to move relative to the cabinet, so that the drawer can be opened relative to the cabinet through the push-open mechanism set in the drawer slide assembly.

[0003] However, due to different usage habits, or because users are unaware that the slide rail assembly or furniture has a push-to-open function, sometimes when the sliding rail (or drawer) is closed relative to the fixed rail (or cabinet), users may still unknowingly pull the sliding rail (or drawer) directly to open it from the closed position. However, this method of opening the sliding rail (or drawer) without pressing may damage the relevant parts of the push-to-open mechanism, causing the push-to-open function to fail. Therefore, products with protective mechanisms have begun to appear on the market.

[0004] For example, US Patent Publication No. 8,857,868B2 discloses an abutment structure for a closing device, which includes a latching block, a positioning hook, and a locking pin. The latching block includes an abutment surface and a guide surface extending from the abutment surface. The positioning hook is connected to the latching block and includes a spring portion and a stop extending from the spring portion, with the stop adjacent to the abutment surface and away from the guide surface. The locking pin corresponds to the latching block and slides against the abutment surface and the stop of the positioning hook. When the sliding rail (or drawer) is opened, the locking pin forcefully abuts against the abutment surface and the stop. The stop is pushed by the locking pin through the flexural deformation of the spring portion, causing the locking pin to pass over the stop and disengage from the abutment surface. The spring portion prevents the latching block from being worn or damaged, thus protecting the relevant parts.

[0005] For example, European Patent Publication No. EP 2272400B1 discloses a locking device for drawer slides, which... Figure 5 The locking device discloses a disc with a protrusion, which, in an initial position, is used to receive or lock one end of a switch assembly (such as its...). Figure 5 (As shown in A). When the slide rail (or drawer) is opened, the end can disengage from the protrusion on the disc by rotating the disc (as shown in A). Figure 5B) It has the function of protecting related parts, and can only return to its original state by the spring force of the spring that opens after the sliding rail (drawer) is closed, that is, the disc can return to the initial position.

[0006] However, in order to meet the diverse needs of the market, how to develop a different product has become an issue that cannot be ignored. Summary of the Invention

[0007] The purpose of this invention is to provide a slide rail assembly with a protection mechanism.

[0008] According to one aspect of the present invention, a slide rail assembly includes a first rail, a second rail, a drive device, a control member, an auxiliary member, a working member, and an elastic structure. The second rail is displaceable relative to the first rail; the drive device is used to provide a retracted position of the second rail relative to the first rail by pressing it open in a first direction, the drive device including an elastic member for providing a spring force in a second direction, wherein the first direction and the second direction are opposite; the control member is movably mounted to one of the first rail and the second rail; the auxiliary member is arranged in the other of the first rail and the second rail, the auxiliary member including a predetermined path; the working member is movable relative to the auxiliary member, the working member including a working portion adjacent to the predetermined path; the elastic structure provides a restoring spring force to the working member, holding the working member in a first state; wherein, when the second rail is in the retracted position relative to the first rail, the control member and the working portion of the working member in the first state can block each other. The control member is placed in a locked position to maintain the elastic force of the elastic member; wherein, when the second rail is pressed relative to the first rail from the closed position along the first direction by a first force, the auxiliary member guides the control member from the locked position to the predetermined path, causing the elastic member to release the elastic force and drive the second rail to open in the second direction; wherein, when the second rail is pulled relative to the first rail from the closed position along the second direction by a second force, the control member and the working part of the working piece in the first state can come into contact with each other to generate a force, causing the working piece to rotate from the first state to a second state, causing the control member to move from the locked position to the predetermined path, thereby allowing the second rail to open in the second direction; wherein, the working piece can return from the second state to the first state in response to the restoring elastic force of the elastic structure.

[0009] According to another aspect of the invention, a slide rail assembly includes a first rail, a second rail, a drive device, a control element, an auxiliary element, a working element, and an elastic structure. The second rail and the first rail are displaceable relative to each other; the drive device is used to provide a pressing action in a first direction relative to the first rail in a retracted position to open the second rail, and the drive device includes an elastic element to provide a spring force in a second direction, wherein the first direction and the second direction are opposite; the control element is movably mounted to one of the first rail and the second rail, and the control element includes a control portion; the auxiliary element is arranged in the other of the first rail and the second rail, and the auxiliary element includes a predetermined path, the predetermined path including an entry section and a release section communicating with the entry section; the working element is movable relative to the auxiliary element, and the working element includes a working portion located between the entry section and the release section; the elastic structure provides a restoring spring force to the working element, causing the working element to remain in a first position. The working part of the workpiece further includes a stop section, which is offset from a center point of the workpiece by a predetermined angle. When the second rail is in the retracted position relative to the first rail, the control member and the working part of the workpiece in the first state can block each other, so that the control member is in a locked position, and the control part of the control member contacts the stop section to maintain the elasticity of the elastic member. When the second rail is pulled out from the retracted position relative to the first rail along the second direction, the control member and the working part of the workpiece in the first state can push against each other to generate a force, so that the workpiece rotates from the first state to a second state, and the control part of the control member moves from the locked position to the predetermined path to allow the second rail to open in the second direction.

In practice, the first rail 22 may be mounted (or fixed) to a cabinet, and the second rail 24 may be used to support a drawer.

[0023] The drive unit 26 is used to provide the second rail 24 relative to the first rail 22 in a retracted position R along a first direction D1 (e.g., a retracting direction, such as...). Figure 1(As shown) Press to open. Preferably, the drive device 26 includes an elastic element 38, such as a spring, but is not limited in implementation, and the elastic element 38 has a first end 40a and a second end 40b positioned opposite each other, wherein the first end 40a of the elastic element 38 is fixed to the first rail 22 through a connector 42, and the second end 40b of the elastic element 38 is disposed with a drive element 44; preferably, the second rail 24 or the third rail 36 is arranged with a corresponding element 46 (or corresponding part) that can be used with the drive element 44, and the position of the corresponding element 46 corresponds to the drive element 44. Here, taking the third rail 36 as an example, in an alternative embodiment, the corresponding element 46 can be arranged on the second rail 24, and is not limited in implementation.

[0024] The control element 28 is movably mounted to one of the first rail 22 and the second rail 24; here, the control element 28 is movably mounted to the first rail 22 as an example. Furthermore, the control element 28 can be pivotally connected to the first rail 22 via a shaft 48, allowing the control element 28 to pivot relative to the first rail 22. Preferably, the first rail 22 includes a first limiting feature 50, and the control element 28 includes a second limiting feature 51 (this part can be referred to in conjunction with...). Figure 6 Preferably, one of the first limiting feature 50 and the second limiting feature 51 is an opening (or a recess), and the other of the first limiting feature 50 and the second limiting feature 51 is an extension leg that can extend into the opening and be limited by the inner wall of the opening, so that the control member 28 can only pivot relative to the first rail 22 within a limited range.

[0025] Preferably, the control element 28 includes a control portion 52, which may be, for example, a protrusion or a pin, but is not limited in implementation.

[0026] Preferably, the first rail 22 has a front end portion 54a and a rear end portion 54b, and the control member 28 is located adjacent to the front end portion 54a of the first rail 22.

[0027] like Figure 3 , Figure 4 and Figure 5 As shown, the auxiliary member 30 is arranged on one of the first rail 22 and the second rail 24, with the example of the auxiliary member 30 being arranged on the second rail 24. Preferably, the auxiliary member 30 is connected (e.g., directly or indirectly fixed) to the second rail 24, which has a front end portion 56a and a rear end portion 56b, and the auxiliary member 30 is arranged on the second rail 24 and adjacent to the front end portion 56a of the second rail 24.

[0028] The working part 32 can move relative to the auxiliary part 30. Here, we take the example of the working part 32 being movably installed to the auxiliary part 30.

[0029] The elastic structure 34 is used to provide a restoring elastic force K to the working member 32, so that the working member 32 is held in a first state S1 (e.g., Figure 4 (As shown). Here, taking the elastic structure 34 as an example of a spring, in an alternative embodiment, the elastic structure 34 can be a spring or other elastic object, and the implementation is not limited.

[0030] Preferably, the auxiliary component 30 includes a space M to allow the workpiece 32 to move, the space M passing through a top 58 and a bottom 60 of the auxiliary component 30 (e.g., Figure 3 (As shown).

[0031] Preferably, the working part 32 includes a main body 62, an extension 64, and a working part 66. The extension 64 extends from the main body 62, and the working part 66 protrudes from the main body 62 and is located on the bottom surface 67 of the main body 62; the main body 62 and the extension 64 are located on the top 58 of the auxiliary part 30 (e.g., Figure 4 As shown), and the working part 66 penetrates the space M and is located at the bottom 60 of the auxiliary member 30 (as shown). Figure 5 (As shown).

[0032] Preferably, the auxiliary component 30 further includes an auxiliary chamber Q for accommodating the elastic structure 34, and the auxiliary chamber Q is adjacent to the space M; the elastic structure 34 includes a first predetermined portion 68 and a second predetermined portion 70, the first predetermined portion 68 abutting against a wall 72 of the auxiliary component 30, and the second predetermined portion 70 contacting an extension 64 of the working component 32 (e.g., Figure 3 and Figure 4 (As shown).

[0033] The auxiliary component 30 includes a predetermined path 74, and the working part 66 of the working component 32 is adjacent to the predetermined path 74 (e.g., Figure 5 (As shown).

[0034] Preferably, the working portion 66 of the working piece 32 is a protrusion with a heart-shaped outline, the predetermined path 74 surrounds the outline of the working portion 66, and the predetermined path 74 includes an entry section 76a and a release section 76b communicating with the entry section 76a; the working portion 66 of the working piece 32 is located between the entry section 76a and the release section 76b (e.g., Figure 5 (As shown).

[0035] Preferably, the auxiliary component 30 further includes a guide section 78, which is, for example, an inclined surface or an arc surface, and the working part 66 of the working component 32 further includes a stop section 80.

[0036] Preferably, the main body 62 (bottom surface 67) of the working part 32 has a substantially circular outline (e.g., Figure 3 or Figure 5 (As shown).

[0037] like Figure 6 As shown, when the second rail 24 is in the retracted position R relative to the first rail 22, the control member 28 and the working part 66 of the working member 32 in the first state S1 can block each other, so that the control member 28 is in a locked position L, so as to maintain the elastic member 38 with a spring force J in a second direction D2 (for example, the opening direction). Wherein, the first direction D1 and the second direction D2 are opposite directions.

[0038] Preferably, when the second rail 24 is in the retracted position R relative to the first rail 22, the control portion 52 of the control member 28 blocks the abutting section 80 of the working portion 66 of the working member 32 in the first state S1, so that the control member 28 is in the locked position L, wherein the control portion 52 of the control member 28 is in contact with the abutting section 80. Furthermore, a locking space X is defined between the guide section 78 and the abutting section 80 to accommodate the control portion 52 of the control member 28.

[0039] Preferably, the abutting section 80 is offset from a predetermined angle A relative to a center point 82 of the working part 32 (the main body 62).

[0040] like Figure 7 , Figure 8 and Figure 9 As shown, when the second rail 24 is pressed relative to the first rail 22 from the retracted position R along the first direction D1 by a first force F1, the auxiliary member 30 guides the control member 28 from the locked position L to the predetermined path 74 (e.g., Figure 7 As shown), the elastic element 38 releases the elastic force J, driving the second rail 24 to open relative to the first rail 22 in the second direction D2 (as shown). Figure 8 As shown), until the second track 24 is displaced to a predetermined extension position E (as shown). Figure 9 As shown), this is the so-called press-to-open function, that is, the user can open the second rail 24 relative to the first rail 22 from the closed position R to the second direction D2 by pressing.

[0041] Preferably, when the second rail 24 is pressed relative to the first rail 22 from the retracted position R along the first direction D1 by the first force F1, the control portion 52 of the control member 28 can contact the guide section 78 of the auxiliary member 30, and through the guidance of the guide section 78, the control member 28 can pivot at an angle, and the control portion 52 of the control member 28 can move from the locked position L to the release section 76b of the predetermined path 74 (e.g., Figure 7As shown), the elastic member 38 releases the elastic force J. For example, the second end 40b of the elastic member 38 can thereby push against the corresponding member 46 of the third rail 36 through the driving member 44, causing the third rail 36 and the second rail 24 to be driven in the second direction D2 and opened (as shown). Figure 8 and Figure 9 (As shown).

[0042] Preferably, the auxiliary component 30 further includes a guide feature 84, which is, for example, an inclined surface or an arc surface; when the second rail 24 moves in the second direction D2 in response to the release of the elastic force J, the auxiliary component 30 can contact the control part 52 of the control component 28 through the guide feature 84, so as to drive the control component 28 to a preparatory position, so that the control part 52 of the control component 28 corresponds to the entry section 76a of the auxiliary component 30 (e.g., Figure 8 and Figure 9 As shown), therefore, when the second track 24 moves from the predetermined extension position E towards the first direction D1 toward the aforementioned retracted position R, the control member 28 (control unit 52) ​​can enter the predetermined path 74 from the entry section 76a of the auxiliary member 30 and return to the aforementioned locking position L (as shown). Figure 6 As shown in the figure, since this part is a technical category that can be understood by those familiar with the field, it will not be elaborated on here for the sake of brevity.

[0043] like Figure 6 and Figure 10 As shown, when the second rail 24 is pulled out from the retracted position R along the second direction D2 relative to the first rail 22 by a second force F2, the control member 28 and the working part 66 of the working piece 32 in the first state S1 can come into contact with each other (e.g., push against each other) to generate a force V, causing the working piece 32 to move out from the first state S1 (e.g., push against each other). Figure 6 (As shown) rotate to a second state S2 (as shown) Figure 10 As shown), the control unit 28 (control section 52) is moved from the locked position L (as shown). Figure 6 As shown) the activity (e.g., driven by the working part 66 of the workpiece 32) to the release segment 76b of the predetermined path 74 (e.g.) Figure 10 As shown), this allows the second track 24 to open directly in the second direction D2.

[0044] Preferably, when the second rail 24 is pulled out relative to the first rail 22 from the retracted position R along the second direction D2 by the second force F2, the abutment section 80 deviates from the predetermined angle A relative to the center point 82 of the working piece 32. This facilitates the contact between the control part 52 of the control member 28 and the working part 66 of the working piece 32 in the first state S1, thereby generating the force V. It also helps the working piece 32 to move from the first state S1 (as if...) Figure 6 (As shown) rotate to the second state S2 (as shown) Figure 10 (As shown), this makes it easier for the control portion 52 of the control member 28 to be moved from the locked position L by the working portion 66 of the working member 32 to the release section 76b of the predetermined path 74, so as to allow the second rail 24 to open in the second direction D2. Preferably, the working portion 66 of the working member 32 also includes a guide surface 55, which is adjacent to the abutment section 80, and the control portion 52 of the control member 28 has a guide profile 59; the guide surface 55 is, for example, a slope or an arc surface, and the guide profile 59 is, for example, a circle or an arc profile; when the second rail 24 is pulled out relative to the first rail 22 from the retracted position R along the second direction D2 by the second force F2, the control member 28 and the working portion 66 of the working member 32 can push against each other through the guide profile 59 and the guide surface 55 to generate the force V, which also helps the working member 32 to open from the first state S1 (as shown). Figure 6 (As shown) rotate to the second state S2 (as shown) Figure 10 As shown), the control part 52 of the control element 28 is easily driven from the locked position L by the working part 66 of the working element 32 to the release section 76b of the predetermined path 74.

[0045] When the working part 32 is in the second state S2, the elastic structure 34 is in a state of accumulating the restoring elastic force K (e.g., Figure 10 (as shown); once the second rail 24 is displaced relative to the first rail 22 in the second direction D2 to a predetermined position (e.g., the predetermined extension position E mentioned above), the working member 32 can be released from the second state S2 (as shown) in response to the release of the restoring elastic force K of the elastic structure 34. Figure 10 (As shown) Return to the first state S1 (as shown) Figure 9 (As shown).

[0046] Therefore, when the second rail 24 is in the closed position R relative to the first rail 22, under proper operation, the user must press the second rail 24 to open it. However, if the user uses an inappropriate operation, such as directly applying a second force F2 to pull the second rail 24 in the second direction D2 (e.g., forcefully pulling), the working part 32 can move relative to the auxiliary part 30 (e.g., rotate), allowing the control part 28 (control section 52) to move from the locked position L to the release section 76b of the predetermined path 74. This prevents wear or damage caused by friction or collision between the working part 32 (working section 66) and the control part 28 (control section 52), thus providing protection.

[0047] Therefore, the slide rail assembly 20 provided in this embodiment of the invention has the following characteristics:

[0048] 1. When the second rail 24 is pulled out relative to the first rail 22 from the retracted position R along the second direction D2 by a second force F2 (e.g., strong pull), the control member 28 and the working part 66 of the working member 32 in the first state S1 can come into contact with each other and generate a force V, causing the working member 32 to move from the first state S1 to the second state S2, and causing the control member 28 to move from the locked position L to the predetermined path 78, so as to allow the second rail 24 to open in the second direction D2. The fact that the working member 32 can move (e.g., rotate) helps the control member 28 (control part 52) ​​to be driven away from the locked position L by the working member 32, or prevents wear or damage that may be caused by friction or collision between the abutment section 80 of the working part 32 (working part 66) and the control member 28 (control part 52).

[0049] 2. The working piece 32 can return from the second state S2 to the first state S1 in response to the restoring elastic force K of the elastic structure 34. For example, once the second rail 24 is displaced relative to the first rail 22 in the second direction D2 to a predetermined position (e.g., a predetermined extension position E), the working piece 32 can return from the second state S2 (e.g., a predetermined extension position E) in response to the release of the restoring elastic force K of the elastic structure 34. Figure 10 (As shown) Return to the first state S1 (as shown) Figure 9 (As shown).

[0050] 3. When the second rail 24 is pulled out relative to the first rail 22 from the retracted position R along the second direction D2 by the second force F2, the center point 82 of the abutment section 80 relative to the main body 62 (bottom surface 67) of the working piece 32 deviates from the predetermined angle A, which helps the working piece 32 to move from the first state S1 (as in...) Figure 6 As shown) the activity (e.g., rotation) to the second state S2 (as shown) Figure 10 As shown), this makes it easier for the control part 52 of the control element 28 to be driven from the locked position L by the working part 66 of the working element 32 to the release section 76b of the predetermined path 74.

[0051] Although the present invention has been described with reference to specific embodiments, those skilled in the art should recognize that the above embodiments are merely illustrative of the invention, and various equivalent changes and modifications can be made without departing from the spirit of the invention. Therefore, any changes or modifications to the above embodiments within the scope of the essential spirit of the invention will fall within the scope of the claims of this application.
