As shown in FIGS. 1 and 2, a cable management arm according to an embodiment of the present invention includes a first arm 10, a second arm 12, a cable base 14, a support base 16, a first connecting unit 18, and a second connecting unit 20. , A third connecting unit 22, a first support member 24, a second support member 26, an elastic member 28, a slide base 30, and a plurality of cable support bases 32. The cable support base 32 is distributed and installed on the first arm 10, the second arm 12, and the cable base 14 and is used for arranging the cables (the cables are not shown).

  The cable base portion 14 is pivotally attached between the first arm 10 and the second arm 12, and the cable base portion 14 has an extension plate 34. In one embodiment, the stretch plate 34 is configured to be fixed to the lower portion of the cable base 14 as one independent component, or the stretch plate 34 is integrally formed with the cable base 14. Thereby, the stretch plate 34 is regarded as a part of the cable base 14. In one embodiment, the stretcher plate 34 includes an arcuate slide groove 36.

  The support base portion 16 includes a first support portion 38 and a second support portion 40 so as to be substantially perpendicular to the first support portion 38.

  The first series connection unit 18 is connected to the first arm 10, and includes a first fitting base portion 42 and a first series contacting base portion 44 that is pivotally attached to the first fitting base portion 42. In one embodiment, the first series contact base 44 is configured to be pivotally attached to the first arm 10.

  The second connecting unit 20 is connected to the second arm 12, and has a second fitting base portion 43 and a second connecting base portion 46 that is pivotally attached to the second fitting base portion 43. In one embodiment, the second connecting base 46 is mounted on the second arm 12.

  The third connecting unit 22 is pivotally attached to the first support portion 38 of the support base 16 using a first pivot member 48.

  The first support member 24 is pivotally attached to the second support portion 40 of the support base 16 using the second pivot member 50, and the first support member 24 is in close contact with the second support portion 40 of the support base 16.

  The second support member 26 is connected to the first support member 24 so as to move. More specifically, the second support member 26 has a passage 52, and the first support member 24 is placed in the passage 52. As a result, the second support member 26 moves relative to the first support member 24. In one embodiment, the first support member 24 includes a first flange 54, and the first flange 54 is configured to extend integrally from the first support member 24. Further, the second support member 26 includes a second flange portion 56, and the second flange portion 56 is integrally extended from the second support member 26, and a first control body 58 is provided at each end of the second support member 26. And a second control body 60.

  The elastic member 28 is connected to the first flange portion 54 of the first support member 24 and the second flange portion 56 of the second support member 26. Accordingly, the second support member 26 has elasticity that is pulled by the elastic member 28 with respect to the first support member 24. In other words, the second support member 26 moves relative to the first support member 24 in accordance with the elasticity generated by the elastic member 28. That is, the second support member 26 is pulled back from the state of being pulled out by the elastic force of the elastic member 28 generated with respect to the first support member 24 and is in a closed state.

  The slide base 30 has a first end 31a and a second end 31b. The first contact member 33 a passes through the arc-shaped slide groove 36 of the extending plate 34 and is connected to the first end 31 a of the adjacent slide base 30. As a result, the slide base 30 can move in the space where the arc-shaped slide groove 36 is restricted with respect to the extending plate 34. Most preferably, the second connecting member 33b is used to axially attach the second end 31b of the adjacent slide base 30 and the extending plate 34 to each other. The slide base 30 is connected between the first control body 58 and the second control body 60 of the second support member 26 so as to move. What should be noted here is that the stretched plate 34 is viewed as a part of the cable base 14 as described above. Thereby, the method of connecting the slide base 30 to the cable base 14 also belongs to the same technical means.

  FIG. 3 shows a state in which the cable management arm of the present invention is attached to a first slide rail kit 62 and a second slide rail kit 64 installed in a pair. The first slide rail kit 62 includes at least a first fixed rail 66 and a first movable rail 68, and the first movable rail 68 slides in the vertical direction with respect to the first fixed rail 66. The second slide rail kit 64 also includes at least a second fixed rail 70 and a second movable rail 72, and the second movable rail 72 slides in the vertical direction with respect to the second fixed rail 70. A server device 74 is attached to the first movable rail 68 of the first slide rail kit 62 and the second movable rail 72 of the second slide rail kit 64, and a cable (not shown) of the server device 74 is connected to the first arm 10 and the second arm. Arranged on the arm 12 and the cable base 14. When the first fitting base portion 42 of the first connecting unit 18 is connected to the first fixed rail 66 of the first slide rail kit 62, one end of the first arm 10 is positioned at the first predetermined position. When the second fitting base portion 43 of the second connecting unit 20 is connected to the first movable rail 68 of the first slide rail kit 62, one end of the second arm 12 is positioned at the second predetermined position. The second predetermined position varies as the first movable rail 68 of the first slide rail kit 62 slides with respect to the first fixed rail 66. In addition, the support base 16 is fixed at the third predetermined position because the third connecting unit 22 is connected to the second fixed rail 70 of the second slide rail kit 64.

  When the first slide rail kit 62 and the second slide rail kit 64 are in a closed state, it is as shown in FIG. The second arm 12 and the first arm 10 are in a state where they face each other and are attached to each other, forming a cantilever shape with a long span, and the center of gravity of the entire cable management arm is P1. The second support member 26 is closed and shortened with respect to the first support member 24, and the first support member 24 presses and supports the support base 16. Therefore, the first arm 10 and the second arm 12 are in a state where they are attached to each other and are mainly supported by the support base 16, so that the burden on the first connecting unit 18 and the second connecting unit 20 is reduced. Get smaller.

  FIG. 4 shows an initial stage in which the first movable rail 68 of the first slide rail kit 62 and the second movable rail 72 of the second slide rail kit 64 are pulled out and extended. The second connecting unit 20 of the second arm 12 is shown in FIG. In this state, the first arm 10 has moved to the first distance L1 with respect to the first series connection unit 18. At this stage, the second support member 26 is limited by the elastic member 28 and is not extended from the first support member 24. When the slide base 30 slides linearly along the second support member 26, the cable base 14 and the extension plate 34 slide on the cable base 14 because the cable base 14 moves in the vertical direction as the second arm 12 moves. The movement of the base 30 and the second support member 26 is transmitted, and the first support member 24 is tilted with respect to the support base 16. At the same time, since the slide base 30 is pivotally attached to the cable base 14 using the second connecting member 33 b, the slide base 30 also moves relative to the cable base 14 and the extending plate 34. Further, since the first series contact member 33a restricts the movement of the slide base 30 within the finite space of the arc-shaped slide groove 36, the center of gravity of the entire cable management arm is P2. In this state, both the support base 16 and the second support member 26 (including the first support member 24) can also provide a support effect.

  FIG. 5 shows a state in which the second connecting unit 20 of the second arm 12 continues to move with respect to the first connecting unit 18 of the first arm 10 and is positioned at the second distance L2. At this time, the cable base 14 and the extending plate 34 slide on the second support member 26 to the first control body 58 by the slide base 30. After the slide base 30 is controlled and stopped by the first control body 58, the second support member 26 driven by the slide base 30 is extended from the first support member 24, and the first support member 24 is also a support base. Tilt to 16. At the same time, the elastic member 28 is pulled by the second support member 26, and generates elasticity to pull back the second support member 26. At this time, the center of gravity of the entire cable management arm is at P3.

  FIG. 6 shows a state where the second connecting unit 20 of the second arm 12 continues to move with respect to the first connecting unit 18 of the first arm 10 and is located at the third distance L3. At this time, the cable base 14 and the extending plate 34 follow the second support member 26 through the slide base 30, and the second support member 26 is further extended from the first support member 24. At the same time, the elastic action by the elastic member 28 continues to be exerted on the second support member 26. In this state, the center of gravity of the entire cable management arm is at P4 and approaches the center of the entire cable management arm. Therefore, the weight load changes, and the support base 16, the first connecting unit 18, and the second connecting unit 20 are in a state of supporting together.

  FIG. 7 shows a state in which the second connecting unit 20 of the second arm 12 has moved to the fourth distance L4 that is completely opened with respect to the first connecting unit 18 of the first arm 10. At this time, the cable base 14 and the extending plate 34 follow the second support member 26 through the slide base 30, and the second support member 26 is completely extended with respect to the first support member 24. At the same time, the second support member 26 still receives the elastic action by the elastic member 28. In this state, the center of gravity of the entire cable management arm is at P5 and approaches the slide rail kit 62. Therefore, most of the entire weight of the cable management arm is supported by the first connecting unit 18 and the second connecting unit 20 together.

  It should be noted that in the process of returning the cable management arm to the closed state, the second support member 26 moves the second support member 26 to the first support member in accordance with the elastic tensile force generated by the elastic member 28. Pull back automatically against 24. That is, when the slide base 30 moves on the second support member 26 toward the support base 16, the slide base 30 continues to press the second control body 60 until the second support member 26 is contracted by the first support member 24. , Completely closed.

  As described above, the slide base 30 is pivotally attached to the extension plate 34 so as to be movable, and the slide base 30 is directly fixed to the extension plate 34 of the cable base 14 so that only the length of the first arm 10 is obtained. The slide base 30 can be slid along the second support member 26 by extending and contracting.

  As shown in FIG. 8, in one embodiment, the support base 16 may connect the third connecting unit 22 to the second movable rail 72 of the second slide rail kit 64. Since the operation principle is similar to the principle of connecting the third connecting unit 22 to the second fixed rail 70 described above, the description is omitted here.

  As shown in FIG. 9, the first support portion 38 of the support base 16 has a first convex portion 76 and a second convex portion 78, and the third connecting unit 22 has a first positioning hole 80 and a second positioning hole 82. . When the third connecting unit 22 moves to the first position in the first direction F1 with respect to the support base 16, the first convex portion 76 of the third connecting unit 22 is inserted into the first positioning hole 80 and positioned. Is decided. When the third connecting unit 22 rotates to the second position in the second direction F2 with respect to the support base 16, the second convex portion 78 of the third connecting unit 22 is inserted into the second positioning hole 82 and positioned. Is decided. Thereby, it can be used when the left and right sides of the entire cable management arm are switched.

  As described above, the cable management arm of the present invention provides a stable support effect in a closed and stationary state, and the entire beam structure when the cable management arm is pulled out and opened varies depending on the operation, thereby sharing the load. It can also provide support during operation and does not cause excessive descent when the cable is placed on the cable management arm.
