Detailed Description

As shown in fig. 1, a slide rail mechanism 20 according to an embodiment of the present invention can be mounted to a first column 26 and a second column 28 of a rack (rack) through a first bracket 22 (also referred to as a bracket) and a second bracket 24 (also referred to as another bracket).

As shown in fig. 2 and 3, the slide rail mechanism 20 includes a rail member 30, a first support frame 32, a second support frame 34, the first bracket 22, and a reinforcement member 36, and preferably further includes a support rail 38.

The rail 30 has a first end 40a and a second end 40b positioned opposite the first end 40 a. The rail 30 includes a first detent structure 42 located between the first end 40a and the second end 40 b.

The support rail 38 is attached, such as fixedly attached, to a back side of the rail member 30 and may be considered part of the rail member 30. For example, the support rail 38 may be riveted, bolted, welded, or the like, to the rail member 30. Further, the support rail 38 has an upper wall 44a, a lower wall 44b, and a longitudinal wall 46 connected between the upper wall 44a and the lower wall 44 b. The upper wall 44a, the lower wall 44b and the longitudinal wall 46 together define a channel 48. Preferably, the longitudinal wall 46 has a first stop feature 50 located within the channel 48. Here, the first limiting feature 50 is exemplified by a protrusion. The second bracket 24 has a side wall 52 and at least one mounting member 53 located adjacent one end of the side wall 52, the side wall 52 being connected to the longitudinal wall 46 of the support rail 38. The at least one mounting member 53 is exemplified by two. Preferably, the second bracket 24 is located adjacent the second end 40b of the rail member 30.

The first support bracket 32 is displaceable relative to the rail member 30. For example, but not limiting in implementation, a portion of the first support frame 32 is movably mounted to the channel 48 of the support rail 38, and the first support frame 32 is capable of moving relative to the rail member 30 through the channel 48 of the support rail 38. The first support frame 32 has an upper wall 54a, a lower wall 54b, and a longitudinal wall 56 connected between the upper wall 54a and the lower wall 54 b. The upper wall 54a, the lower wall 54b and the longitudinal wall 56 together define a channel 58. Further, the first support frame 32 has a second stop feature 60, the second stop feature 60 is connected to the longitudinal wall 56 of the first support frame 32, and the second stop feature 60 is located corresponding to the first stop feature 50 of the support rail 38. Here, the second limiting feature 60 is exemplified by an extension arm. Preferably, the first support frame 32 further includes an opening 62 and a contact wall 64 adjacent to the opening 62 (see fig. 4). Wherein the opening 62 is longitudinally disposed. Preferably, the first support frame 32 further includes a guiding surface 66 (e.g., a slant surface or a curved surface), and the contact wall 64 and the guiding surface 66 are respectively located at two sides of the opening 62.

The second support bracket 34 is displaceable relative to the first support bracket 32. For example, but not limited to, a portion of the second support bracket 34 is movably mounted to the channel 58 of the first support bracket 32, and the second support bracket 34 is displaceable relative to the first support bracket 32 through the channel 58 of the first support bracket 32. The second support bracket 34 includes a resilient arm 67 and an abutting portion 68 disposed on the resilient arm 67, wherein the resilient arm 67 extends from the second support bracket 34. The abutting portion 68 can be used to be inserted into the opening 62 of the first support frame 32, and the size of the abutting portion 68 is smaller than that of the opening 62. Preferably, the second support bracket 34 includes a support structure 70, an extension 72 and a guide structure 74. The extension 72 is located between the support structure 70 and the guide structure 74.

The first bracket 22 and the second bracket 34 are movable relative to each other. Preferably, the first bracket 22 is adjustable to be positioned adjacent the first end 40a of the rail member 30. The first bracket 22 includes a side wall 76, an end wall 77 and at least one mounting member 78. The end wall 77 is substantially vertically connected to the side wall 76; the at least one mounting member 78 is disposed on the end wall 77, where the at least one mounting member 53 is illustrated in two. The slide mechanism 20 further includes a fastener 80 movably mounted to the first bracket 22.

Further, the side wall 76 of the first bracket 22 further has a first wall 82a and a second wall 82b defining a space 84 therebetween. The second support bracket 34 is displaceable within the space 84. Preferably, the fastener 80 is pivotally connected to the first bracket 22 through a shaft 85, for example, the fastener 80 is pivotally connected to the first wall 82 a; the fastener 80 includes a supporting leg 86 and a guiding leg 88. Preferably, the fastener 80 further comprises a mounting portion 90, a fastening portion 92 and an arm portion 94 located between the mounting portion 90 and the fastening portion 92. Here, the supporting leg 86 and the guiding leg 88 are spaced apart from each other. The supporting legs 86 and the guiding legs 88 are bent relative to the mounting portion 90, and the supporting legs 86 and the guiding legs 88 are located in the space 84 adjacent to the first bracket 22.

Preferably, one of the first bracket 22 and the second bracket 34 includes a limiting structure 96, and the second bracket 34 and the first bracket 22 can be displaced relative to each other within a limited range through the limiting structure 96. Here, the limiting structure 96 can be a long hole with a boundary, and the slide rail mechanism 20 further includes a connecting member 98 passing through a portion of the limiting structure 96 for connecting the second supporting frame 34 to the first bracket 22.

Preferably, the slide mechanism 20 further includes an elastic member 100 attached to the second support frame 34. For example, the elastic member 100 can be connected to the second supporting frame 34 by riveting or screwing. The resilient member 100 has a first detent feature 102; on the other hand, the first bracket 22 includes a second latching feature 104, and the first latching feature 102 can latch in the second latching feature 104. The first latching feature 102 and the second latching feature 104 may be concave (or hole) or convex, or may be a matching structure of convex or concave (or hole), for example, the first latching feature 102 is a convex portion, and the second latching feature 104 is a positioning hole, but the implementation is not limited.

The reinforcing member 36 is mounted, for example, movably mounted on the rail 30 and the first support frame 32, so as to reinforce the supporting structure of the rail 30 and the first support frame 32. Specifically, the reinforcing member 36 includes a second engaging structure 106, and the reinforcing member 36 can be used to engage the first engaging structure 42 of the rail member 30 through an engaging portion 108 of the second engaging structure 106. Herein, the second latching structure 106 is exemplified by an elastic fitting, which can be connected to the reinforcing member 36 by riveting or screwing, and thus can be regarded as a part of the reinforcing member 36. The first latching structure 42 and the latching portion 108 of the second latching structure 106 may be concave (or hole) or convex, or may be a structure matching convex or concave (or hole), but the implementation is not limited thereto. On the other hand, the first bracket 22 includes a releasing structure 109 for releasing the latching portion 108 of the second latching structure 106 of the reinforcing member 36 from the first latching structure 42 of the rail member 30.

Preferably, the reinforcing member 36 further includes a main body 110, at least one first clasping portion 112 and at least one second clasping portion 114 respectively located at two sides of the main body 110, and at least one first feature 116 located at the main body 110. Here, two first clasping portions 112 and two second clasping portions 114 are taken as an example.

The two first clasping portions 112 can be respectively used for supporting the upper portion and the lower portion of the rail member 30; the two second clasping portions 114 can be respectively used for supporting the first supporting frame 32 (for example, the upper wall 54a and the lower wall 54b of the first supporting frame 32); in another aspect, the first support frame 32 includes at least one second feature 118 (see fig. 4). The at least one second feature 118 is located on the longitudinal wall 56 of the first support frame 32, and the at least one second feature 118 is engaged with the at least one first feature 116 of the reinforcement member 36. Therefore, the first support frame 32 and the reinforcing member 36 can be regarded as a single body. The at least one second feature 118 is exemplified by a latching portion, and the at least one first feature 116 may be a mounting hole for latching and positioning the at least one second feature 118. In this embodiment, two second features 118 and two first features 116 are taken as an example.

As shown in fig. 5, one of the support leg 86 of the fastener 80 and the support structure 70 of the second support frame 34 includes at least one guide section. The at least one guiding section may be an inclined surface or an arc surface. Here, for example, the supporting structure 70 includes a first guiding section 120, and the supporting structure 70 further includes a supporting section 122 adjacent to the first guiding section 120. When the second supporting frame 34 is located at a first position P1 (also referred to as a position) relative to the first bracket 22, the supporting structure 70 of the second supporting frame 34 and the supporting leg 86 of the fastening member 80 define a predetermined distance therebetween, so that the supporting structure 70 of the second supporting frame 34 cannot provide the supporting leg 86 of the fastening member 80 to abut against, and the fastening member 80 can be located at a first state S1 (e.g., a locked state) relative to the at least one mounting member 78. It should be noted that in the first state S1, the fastening portion 92 of the fastening member 80 is close to the at least one mounting member 78.

As shown in fig. 6, when the second supporting frame 34 moves away from the first position P1 relative to the first bracket 22, the supporting structure 70 of the second supporting frame 34 can provide the supporting foot 86 of the fastening member 80 to abut or support, so that the fastening member 80 is no longer in the first state S1 relative to the at least one mounting member 78. The limiting structure 96 and the connecting member 98 are used to limit the displacement of the second supporting frame 34 and the first bracket 22 relative to each other.

Specifically, when the second supporting frame 34 is shifted from the first position P1 to a second position P2 in a first direction D1 relative to the first bracket 22, the supporting structure 70 of the second supporting frame 34 contacts the supporting leg 86 through the first guiding section 120 to drive the fastening device 80 to deflect an angle until the second supporting frame 34 is at the second position P2, the supporting section 122 of the supporting structure 70 of the second supporting frame 34 can provide the supporting leg 86 of the fastening device 80 to abut against, so that the fastening device 80 is switched from the first state S1 to a second state S2 (e.g., an unlocked state) relative to the at least one mounting device 78, and the supporting leg 86 abuts against through the supporting structure 70 of the second supporting frame 34, so that the fastening device 80 can be maintained in the second state S2; on the other hand, when the second supporting frame 34 is at the second position P2 relative to the first bracket 22, the guiding structure 74 of the second supporting frame 34 is located corresponding to the guiding foot 88 of the fastener 80. It should be noted that one of the guiding structure 74 of the second supporting frame 34 and the guiding leg 88 of the fastener 80 can be an inclined surface or an arc surface. In addition, when the second supporting frame 34 moves away from the first position P1 to the second position P2 relative to the first bracket 22, the fastener 80 can be in the second state S2. In the second state S2, the fastening portion 92 of the fastening member 80 is away from the at least one mounting member 78.

As shown in fig. 7, when the second supporting frame 34 is located at the first position P1 relative to the first bracket 22, the second supporting frame 34 is clamped to the second clamping feature 104 of the first bracket 22 through the first clamping feature 102 of the elastic member 100, and the first clamping feature 102 corresponds to a blocking wall 124 of the second clamping feature 104. Accordingly, the second supporting frame 34 can be maintained at the first position P1 relative to the first bracket 22.

As shown in fig. 8, the operation mode can be selected to directly operate the first latching feature 102 of the resilient member 100 to release the second latching feature 104 of the first bracket 22, and then displace the second supporting frame 34 relative to the first bracket 22 from the first position P1 to the first position D1 to the second position P2. Alternatively, the first latching feature 102 is designed to have a guiding mechanism, such as a slope or a cambered surface, relative to the second latching feature 104, so that the first latching feature 102 can be disengaged from the second latching feature 104 by the displacement of the second supporting frame 34 relative to the first bracket 22.

As shown in fig. 9, when the second supporting frame 34 is located at the second position P2 relative to the first bracket 22, the supporting structure 70 of the second supporting frame 34 can provide the supporting foot 86 of the fastening member 80 to abut against, so that the fastening member 80 is located at the second state S2 relative to the first column 26 (also referred to as "column"). Wherein the buckle portion 92 of the buckle 80 is away from the at least one mounting member 78, and the buckle portion 92 fails to lock the first mast 26. Further, when the first bracket 22 is to be installed on the first mast 26, the user can advance the first bracket 22 in a second direction D2 (e.g., a direction opposite to the first direction D1) such that the at least one mounting member 78 of the first bracket 22 enters the at least one hole 126 of the first mast 26 and the first bracket 22 abuts against the first mast 26.

As shown in fig. 10, when the first bracket 22 abuts against the first mast 26, the user can apply a force in the second direction D2 to move the second supporting frame 34 relative to the first bracket 22 from the second position P2 to the first position P1 in the second direction D2, so that the supporting structure 70 of the second supporting frame 34 cannot provide the supporting foot 86 of the fastener 80 to abut against, and the fastener 80 can be operated to recover the first state S1. Preferably, in response to the second supporting frame 34 being displaced from the second position P2 to the second direction D2 relative to the first bracket 22, the guiding structure 74 can drive the guiding leg 88 of the fastening member 80, so that the fastening member 80 is restored from the second state S2 to the first state S1. Wherein the fastening portion 92 of the fastener 80 is adjacent to the at least one mounting member 78, and the fastening portion 92 is capable of locking the first mast 26. Thus, the process of mounting the first bracket 22 to the first mast 26 is completed.

As shown in fig. 11, the operator may pre-stretch the slide mechanism 20 to make the slide mechanism 20 in an extended state having a first length L1. Specifically, the first supporting frame 32 can be displaced relative to the rail member 30 in the second direction D2 to be in an extended state relative to the supporting rail 38, and the second supporting frame 34 can be displaced relative to the first supporting frame 32 in the second direction D2 to be in an extended state.

The second limit feature 60 of the first support frame 32 can abut against the first limit feature 50 of the support rail 38 (see fig. 12).

Since the at least one second feature 118 of the first support frame 32 is engaged with the at least one first feature 116 of the reinforcement member 36, the reinforcement member 36 can move to a predetermined position relative to the rail member 30 in response to the displacement of the first support frame 32 relative to the rail member 30 and/or the support rail 38 in the second direction D2, so that the reinforcement member 36 is engaged with the first engaging structure 42 of the rail member 30 through the engaging portion 108 of the second engaging structure 106 (see fig. 13). Accordingly, the first support frame 32 can be temporarily fixed relative to the rail 30 by the reinforcement member 36 being engaged with the rail 30. The second supporting frame 34 can be displaced in the second direction D2 relative to the first supporting frame 32 until the abutting portion 68 of the second supporting frame 34 enters the opening 62 of the first supporting frame 32, and the abutting portion 68 can abut against the contact wall 64 of the first supporting frame 32 (see fig. 13).

The support section 122 of the support structure 70 of the second support frame 34 can provide support or abutment for the support leg 86 of the fastener 80 (see fig. 14), so that the fastener 80 is in the second state S2 relative to the at least one mounting member 78. Wherein the fastening portion 92 of the fastening member 80 is away from the at least one mounting member 78; on the other hand, when the second supporting frame 34 is located at the second position P2 relative to the first bracket 22, the guiding structure 74 of the second supporting frame 34 is located corresponding to or adjacent to the guiding leg 88 of the fastener 80; on the other hand, the first latching feature 102 of the elastic member 100 of the second support bracket 34 is not latched to the second latching feature 104 of the first bracket 22.

When mounting the slide mechanism 20 to the first mast 26 and the second mast 28, a user can first advance the slide mechanism 20 in the second direction D2 such that the at least one mounting member 78 of the first bracket 22 faces the at least one hole 126 of the first mast 26.

As shown in fig. 15, after the at least one mounting member 78 of the first bracket 22 of the sliding track mechanism 20 enters the at least one hole 126 of the first column 26, the first bracket 22 (e.g., the end wall 77) can abut against the first column 26. Further, an operator may apply a force in the second direction D2, for example, apply a force to the slide rail mechanism 20 in the second direction D2, so that the second supporting frame 34 is displaced from the second position P2 to the second direction D2 relative to the first bracket 22 to the first position P1, in other words, the supporting section 122 of the supporting structure 70 of the second supporting frame 34 fails to provide the supporting foot 86 of the fastening 80 to abut against (this portion may refer to fig. 16), so that the fastening 80 is operable to return to the first state S1. Wherein, the first latching feature 102 of the elastic member 100 of the second supporting frame 34 can be latched to the second latching feature 104 of the first bracket 22. Further, in response to the displacement of the second supporting frame 34 relative to the first bracket 22, the guiding structure 74 can drive the guiding leg 88 of the fastening member 80, so that the fastening member 80 swings at an angle from the second state S2 to return to the first state S1. The fastening portion 92 of the fastening member 80 is adjacent to the at least one mounting member 78, and the fastening portion 92 is used for locking the first column 26. Preferably, when the fastener 80 is in the first state S1, the extending portion 72 of the second supporting frame 34 can provide the guiding foot 88 to abut against, so that the fastener 80 is kept in the first state S1. It should be noted that, as shown in fig. 14 and 16, the supporting foot 86 of the fastening member 80 has a second guiding section 128. In a process of moving the second supporting frame 34 relative to the first bracket 22 from the first position P1 to the first direction D1 (e.g., a direction opposite to the second direction D2) to the second position P2 through the first guiding section 120 or the second guiding section 128 (see fig. 16 and 14), the second supporting frame 34 can easily drive the fastener 80 to be switched from the first state S1 to the second state S2.

As shown in fig. 17, after completing the operation of mounting the first bracket 22 to the first mast 26, the operator can operate the rail 30 to displace in the first direction D1 relative to the second support bracket 34, so that the at least one mounting member 53 of the second bracket 24 enters the at least one hole 130 of the second mast 28. Since this part is within the technical scope that can be understood by a person skilled in the art, it is not described herein for the sake of brevity. It can be seen that the track mechanism 20 can be mounted to the first mast 26 and the second mast 28. It should be noted that the first bracket 22 and the second bracket 24 can be detached from the first mast 26 and the second mast 28, respectively (see fig. 17, 15 and 11 for brevity, which is not described herein again).

As shown in fig. 18 and 19, the slide rail mechanism 20 can be operated from the extended state to a retracted state. Specifically, an operator can displace the second supporting frame 34 in the first direction D1, wherein the releasing structure 109 of the first bracket 22 can contact the latching portion 108 of the second latching structure 106 of the reinforcing member 36 (see fig. 20).

As shown in fig. 21 and 22, when the second supporting frame 34 continues to be displaced in the first direction D1, the releasing structure 109 of the first bracket 22 can release the engaging portion 108 of the second engaging structure 106 of the reinforcing member 36 from the first engaging structure 42 of the rail member 30, so that the first supporting frame 32 can be displaced relative to the rail member 30. Preferably, one of the releasing structure 109 of the first bracket 22 and the latching portion 108 of the second latching structure 106 has an inclined surface or an arc surface, which helps the releasing structure 109 release the latching portion 108 of the second latching structure 106 of the reinforcing member 36 from the first latching structure 42 of the rail member 30.

As shown in fig. 23, after the first supporting frame 32 is relatively movable with respect to the rail 30, the first bracket 22, the second supporting frame 34, and the first supporting frame 32 can be folded with respect to the rail 30 and/or the supporting rail 38, so that the slide rail mechanism 20 is in the folded state and has a second length L2.

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

1. with the help of the arrangement, an operator can finish the assembly and disassembly of the sliding rail mechanism to two machine columns of the rack by one person in front of the rack, and the operation is very convenient and fast.

2. The first support frame can be temporarily clamped on the rail piece through the reinforcing piece, so that when the first bracket is abutted to the first machine column and the sliding rail mechanism is operated to move forward in the direction of the first machine column, the second support frame is favorable for driving the fastener, the fastener is enabled to be converted into the first state from the second state, for example, the fastener can be enabled to be converted into the locking state from the unlocking state, and the fastener can be used for locking the machine column of the machine frame.

3. The reinforcing part can move relative to the rail part and/or the first support frame, and the reinforcing part comprises a first holding part and a second holding part which can respectively provide supporting functions for the rail part and the first support frame, so that the structural strength of the sliding rail mechanism is improved. For example, the structural strength of the slide rail mechanism in the extended state is facilitated.

4. The sliding rail mechanism comprises two supporting frames, so that the bracket can have two sections of adjustable extension lengths to correspond to different distances between the two machine columns.

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.
