That is, when the ON operation button 102 is pressed, the ON operation button 102 enters below the support bar lock pin 105, so that the support bar lock pin 105 is pushed upward by the ON operation button 102. As a result, the support bar lock pin 105 protrudes upward from the upper end of the support bar 100.

On the other hand, when the OFF operation button 103 is pressed, the ON operation button 102 is pushed back by the OFF operation button 103 and jumps out in the opposite direction to the side where the OFF operation button 103 is located. As a result, the ON operation button 102 moves from below the support bar lock pin 105 and is not positioned below the support bar lock pin 105. Therefore, the support bar lock pin 105 is lowered by its own weight. Further, in the support bar 100, an interlocking member 106 that can be moved up and down by an external force is disposed below the support bar lock pin 105, and the ON operation button 102 is provided from below the support bar lock pin 105. When moved, the support bar lock pin 105 is lowered to a position where it contacts the interlocking member 106. When the OFF operation button 103 is pressed, the support bar lock pin 105 is lowered to the position where it comes into contact with the interlocking member 106 in this way, so that it does not jump out from the upper end of the support bar 100.

Specifically, the length of the entire support member 80 can be adjusted by connecting a plurality of support rods 100. The movement of the support bar lock pin 105 with respect to the operation of the operation button 101 when the support bar 100 is connected will be described. When a plurality of support bars 100 are connected, the interlocking member 106 included in the support bar 100 has a lower side. This is interlocked with the movement of the support bar lock pin 105 of the support bar 100.

In other words, when the support bar lock pin 105 of the lower support bar 100 does not protrude from the upper end of the support bar 100, the interlock member 106 moves from the support bar lock pin 105. Since no force is input, the support rod 100 is lowered by its own weight.

On the other hand, when the support bar lock pin 105 of the support bar 100 connected to the lower side of the support bar 100 having the interlocking member 106 protrudes upward, the interlocking member 106 supports this support from below. When the rod lock pin 105 is pressed, the interlocking member 106 also moves upward. When the interlocking member 106 moves upward, the interlocking member 106 pushes the support rod lock pin 105 positioned above the interlocking member 106 upward, and the support rod lock pin 105 is moved upward from the upper end of the support rod 100. It will be in a state protruding. For this reason, even when the operation button 101 of the support bar 100 is in the state in which the OFF operation button 103 is pressed, the support bar lock pin 105 is interlocked with the movement of the support bar lock pin 105 of the lower support bar 100. When the lower support bar lock pin 105 protrudes upward, the support bar lock pin 105 of the support bar 100 also protrudes upward.

When the support bar 100 is connected, the support bar lock pin 105 is interlocked with the support bar lock pin 105 of the lower support bar 100 in this way. Except for the support rod 100 that is positioned, all the OFF operation buttons 103 are pressed, and the operation buttons 101 are turned OFF.

FIG. 27 is an explanatory view showing a state where a support bar is added below the support bar shown in FIG. Further, when the support rod 100 is added, similarly, the operation button 101 of the support rod 100 newly added at the lowermost stage is connected in the ON state, so that the operation button 101 is positioned on the upper side of the support rod 100. The operation button 101 of the support rod 100 in which 101 is turned on is turned off. That is, when the main body 60 is attached to the base 20 using the support member 80, when connecting a plurality of support bars 100, only the operation button 101 of the lowermost support bar 100 is turned ON, and the other support is performed. The operation button 101 of the stick 100 is turned off. Thus, the operation of the support bar lock pin 105 of the support bar 100 connected to the holding mechanism 81 can be performed by the operation button 101 of the lowermost support bar 100.

FIG. 28 is a perspective view when the main body is attached to the base. By holding the wireless access point 10 by the support member 80, when the main body 60 reaches the base 20, the main body 60 enters the base 20 from the side where the communication plug 72 is located. The main body portion 60 enters the base portion 20 from the opening portion of the base portion 20 that opens downward. At that time, in the main body 60, the first lock pin 64 in the main body lock pin 63 is positioned on the first lock pin hole 24 side in the lock pin hole 23 formed in the base portion 20, and the second lock pin 65. Is inserted in the direction positioned on the second lock pin hole 25 side.

When the main body portion lock pin 63 is properly oriented with respect to the lock pin hole 23 and the main body portion 60 enters the base portion 20 from the side where the communication plug 72 is located, the main body portion lock pin 63 is inserted into the lock pin hole 23. It enters the guide groove 30 through the lock pin hole 23. That is, the main body lock pin 63 enters the passage portion 31 from the opening portion 32 of the passage portion 31 included in the guide groove 30. When the main body portion 60 is moved upward as it is by lifting the support member 80, the main body portion lock pin 63 is moved from the open portion 32 side to the end portion on the side where the engaging portion 34 in the passage portion 31 communicates. It moves in the passage portion 31 toward a certain engagement portion communication portion 33.

Further, when the main body 60 enters the base 20, the main body 60 abuts on the main body attitude adjustment unit 26 provided in the base 20. Since the urging force is applied to the main body portion posture adjustment unit 26 from the plurality of adjustment portion springs 27, the main body portion 60 in contact with the main body portion posture adjustment portion 26 has a cylindrical shape that is the shape of the main body portion main body 61. The posture is adjusted so that the axial direction is a direction along the axial direction of the rectangular tube that is the shape of the base portion main body 21. The communication plug 72 provided in the main body portion 60 is connected to the communication receptor 46 disposed in the base portion 20 in a state where the posture of the main body portion 60 is adjusted as described above.

The communication receptor 46 of the base unit 20 is electrically connected to the RJ45 receptor 45 to which the RJ45 plug 7 of the server side LAN cable 5 is connected, and the communication plug 72 of the main body unit 60 is connected to the wireless access point 10. It is electrically connected to the RJ45 receptor 11.

When the main body portion 60 is further moved upward in a state where the communication plug 72 is connected to the communication receptor 46, the main body portion lock pin 63 positioned in the passage portion 31 of the guide groove 30 becomes the engagement portion communication portion. The position 33 is reached. When the main body lock pin 63 reaches the engaging portion communication portion 33, the main body lock pin 63 can no longer be moved upward, and the main body portion 60 can be moved further upward. Disappear. When the support member 80 stops moving upward, the worker W holding the support member 80 rotates the support member 80 to the side where the engaging portion 34 is located with respect to the main body lock pin 63.

Since the communication receptor 46 of the base unit 20 to which the communication plug 72 of the main body unit 60 is connected is provided on the rotating member 40, the main body unit 60 rotates by rotating the support member 80. When the communication plug 72 is rotated, the entire rotation member 40 is rotated together with the communication plug 72. Thereby, the main body 60 can be rotated while maintaining the connection between the communication plug 72 and the communication receptor 46.

Further, when the main body portion lock pin 63 rotates the main body portion 60 in a direction toward the side where the engaging portion 34 is located, the main body portion lock pin 63 is in a state of entering the passage portion 31 of the guide groove 30. The engagement portion communication portion 33 moves in the groove width direction of the passage portion 31. As a result, the main body lock pin 63 enters the engagement portion 34 and engages with the engagement portion 34. Since the two guide grooves 30, the first lock pin 64, and the second lock pin 65 are provided at positions that are point-symmetric respectively, the two main body portion locks can be obtained by rotating the main body portion 60. Each of the pins 63 engages with the engaging portion 34 of the guide groove 30.

FIG. 29 is a perspective view showing a state where the main body is attached to the base. FIG. 30 is a side view showing a state in which the main body is attached to the base. Specifically, when the support member 80 is rotated, the main body lock pin 63 moves from the passage portion 31 side to the engagement portion 34 side and comes into contact with the groove wall of the engagement portion 34, so that the rest is the same. It will not move in the direction. As a result, the main body 60 does not rotate, and when the main body 60 stops rotating, the operator W lowers the support member 80 downward. As a result, the main body lock pin 63 moves to the lower end in the engagement portion 34 and engages with the engagement portion 34.

When the main body lock pin 63 is engaged with the engaging portion 34, the contact 51 of the attachment completion notifying means 50 provided on the base portion 20 contacts and is electrically connected to the electrode 75 provided on the main body lock pin 63. The Since the electrode 75 provided on the main body lock pin 63 is connected to the button battery 76, when the electrode 75 provided on the main body lock pin 63 and the contact 51 of the attachment completion notification means 50 come into contact, the button battery The electric power of 76 flows to the attachment completion notifying means 50. The LED 52 included in the attachment completion notifying unit 50 is lit for a certain period of time by the electric power supplied from the button battery 76 as described above.

The worker W supporting the support member 80 below the ceiling 2 recognizes that the main body lock pin 63 and the engaging portion 34 are engaged by visually recognizing that the LED 52 is lit. The operator W who recognizes that the main body portion lock pin 63 and the engaging portion 34 are engaged removes the support member 80 from the wireless access point 10.

FIG. 31 is an explanatory diagram when the support member is removed from the wireless access point. When the support member 80 is removed from the wireless access point 10, the operation button 101 is turned off by pressing the OFF operation button 103 of the support bar 100. At that time, when a plurality of support bars 100 are connected, the lowermost operation button 101 is turned off. As a result, the support bar lock pin 105 of the support bar 100 connected to the holding mechanism 81 is lowered by its own weight, so that the slider 85 of the holding mechanism 81 can move to the side where the shutter 88 is located. For this reason, the slider 85 to which the urging force is applied by the slider spring 87 moves in the direction of the shutter 88, and the shutter 88 falls by the movement of the slider 85. That is, the holding mechanism 81 is released.

Since the wireless access point 10 is attached to the base unit 20 via the main body 60, the wireless access point is moved by moving the support member 80 to the side where the stopper 84 is located in a state where the shutter 88 is tilted. 10 can be pulled out from the shutter 88 side. As a result, the support member 80 is removed from the wireless access point 10, and the wireless access point 10 is installed on the ceiling 2 with the RJ45 receptor 11 electrically connected to the RJ45 plug 7 of the server-side LAN cable 5. Is done.

Next, a method for removing the wireless access point 10 installed on the ceiling 2 when performing maintenance or replacement of the wireless access point 10 will be described. When removing the wireless access point 10, the length of the support member 80 is such that the upper end holding mechanism 81 reaches the wireless access point 10 installed on the ceiling 2 by connecting the plurality of support rods 100. To. When the length of the holding mechanism 81 reaches the wireless access point 10, the level 110 is attached to the lowermost support rod 100. In this case, all the operation buttons 101 of the support bar 100 are turned off.

The leveler 110 can visually recognize the inclination of the support member 80 by the horizontal needle 113, and emits a sound from the buzzer 114 when the support member 80 is in a vertical state. For this reason, the worker W makes the support member 80 vertical by visually recognizing the horizontal needle 113 or listening to the sound from the buzzer 114, and in this state, the side support is provided from the shutter 88 side of the holding mechanism 81. The wireless access point 10 is passed between the 95 support units 96. When the support member 80 is in the vertical state, the device receiving portion 82 of the holding mechanism 81 is in a horizontal state, and therefore, in the support portion 96, below the portion that holds the upper side of the side surface of the wireless access point 10, The wireless access point 10 can be passed smoothly.

When the wireless access point 10 is passed between the support portions 96 of the side supports 95, the support member 80 is further moved in the direction in which the holding mechanism 81 moves toward the shutter 88, so that the wireless access point 10 becomes the stopper 84. Make contact. In this state, the holding mechanism 81 is further moved in the same direction, thereby moving the slider 85 connected to the stopper 84 and raising the shutter 88, so that the wireless access point 10 is sandwiched between the stopper 84 and the shutter 88. Set to the state to hold.

Thus, when the shutter 88 is raised, the operation button 101 of the support bar 100 located at the lowermost stage among the support bars 100 is turned on. As a result, the support bar lock pin 105 of the support bar 100 connected to the holding mechanism 81 protrudes upward and restricts the movement of the stopper 84, thereby holding the wireless access point 10 between the stopper 84 and the shutter 88. State is maintained. That is, the holding mechanism 81 is in the holding state of the wireless access point 10.

When the holding mechanism 81 is in the holding state of the wireless access point 10, the support member 80 is once lifted up so that the main body lock pin 63 in the engaging portion 34 faces the side where the passage portion 31 is located. The support member 80 is rotated in the direction in which the main body 60 is rotated. That is, the opposite operation when the main body 60 is attached to the base 20 is performed on the support member 80. When the main body portion lock pin 63 moves to the passage portion 31 by rotating the main body portion 60, the support member 80 is lowered as it is. As a result, the communication plug 72 of the main body portion 60 comes out of the communication receptor 46 of the base portion 20, and the main body portion lock pin 63 comes out of the guide groove 30 from the opening portion 32 of the passage portion 31. , Passes through the lock pin hole 23 downward.

When the main body lock pin 63 comes out of the guide groove 30, the main body 60 can be pulled out from the base portion 20 by lowering the support member 80 as it is. When the main body portion 60 is removed from the base portion 20, the wireless access point 10 held by the holding mechanism 81 is removed from the holding mechanism 81. However, since the support member 80 is long, the support member 80 remains as it is. In some cases, the wireless access point 10 cannot be removed by defeating 80. In this case, the wireless access point 10 is removed after the length of the entire support member 80 is shortened by releasing the connection of the support rod 100.

FIG. 32 is an explanatory diagram for shortening the support member holding the wireless access point. When the connection of the support bar 100 is released and the support bar 100 is removed, the support bar 100 located on the lowermost side is removed. When removing the support bar 100 located on the lowermost stage side, the operation button 101 of the support bar 100 is removed by removing the lowermost support bar 100 while pressing the ON operation button 102 of the support bar 100 immediately above it. Is turned on. As a result, the support bar lock pin 105 of the support bar 100 coupled to the holding mechanism 81 is protruded upward, and the state where the wireless access point 10 is held by the holding mechanism 81 is maintained, and the lowermost support bar 100 is moved.
