The common lighting fixture mounting 100 for lighting according to the present invention includes a buried pipe 110 embedded in the ceiling 10 having a hollow through which the tension cable 114a including the extension 30 passes, and a tension cable 114a. Elevator 120 is disposed on both sides of the passage 112 to be inserted, and a pair of supports (140, 140 ') are shot below the elevator 120 and arranged side by side in the longitudinal direction of the buried pipe (110) and , A plurality of pivots 130, 130 ', 130 "disposed at a predetermined interval on the pair of supports 140, 140', respectively, and rotated along the moving direction of the supports 140, 140 ', and an extension ( 30 is provided with a bar-shaped terminal 151 electrically connected to the cap 150 for covering and closing the upper end of the buried pipe 110, and the lighting member 170 is provided with a lighting means 173, such as a lamp And a controller 180 for checking the abnormality of the lighting member 170 and controlling the elevator 120.

Buried pipe 110 is a pipe shape having a hollow for wrapping and protecting the tension cable (114a) to be embedded and wired in the ceiling 10, it is embedded in the ceiling 10 in the longitudinal direction so that the bottom is exposed. At this time, the tension cable (114a) is drawn through the passage 112 located at the upper end of the buried pipe 110, and drawn out toward the lighting member 170 installed on the ceiling 10 to be electrically connected with the lighting member 170. Is connected.

Here, the buried pipe 110 is fixed to the fixing 114 is drawn from the tension cable 114a made of a material having a sufficient rigidity to support the lighting member 170 while receiving the internal wire 30 drawn from the outside. Include.

The lighting member 170 moves up and down by the elevator 120, and the tension cable 114a directly supports the moving lighting member 170. That is, the tension cable 114a supplies power necessary for driving the lighting member 170 through the received extension 30 and, of course, supports the lighting member 170 so as not to fall.

As described above, the inner line 30 introduced into the buried pipe 110 is wrapped in the tension cable 114a while penetrating through the holder 114, and the tension cable 114a is firmly connected to the holder 114 to illuminate the lamp. Support member 170.

On the other hand, the tension cable 114a drawn out through the lower end of the buried pipe 110 enters the buried pipe 110 with the lifting and lowering of the lighting member 170, while the tension cable 114a is smoothly entered without friction. It further includes a guide roller 116 for guiding the entry point to maintain one point.

The elevator 120 is disposed side by side on both sides of the passage 112, respectively, and applies a pulling force upward as well as pushing downward. To this end, the elevator 120 includes a pair of drive motors 121 fixedly arranged at the upper end of the buried pipe 110 and a nut groove 124a which is rotated by the rotational force of the drive motor 121 and a thread is formed on the inner circumferential surface thereof. The formed nut 122, a screw thread engaged with the thread of the nut groove 124a is formed on the circumferential surface thereof, the screw 123 engaged with the nut 122, and the lift table 124 fixed to the lower end of the screw 123. It is composed of

For reference, the buried pipe 110 is formed with receiving grooves 111 and 111 ′ for accommodating the driving motor 121, the nut 122, the screw 123, and the platform 124 on both sides of the passage 112, respectively. Thus, the screw 123 and the lifting table 124 can be lifted up and down without being separated from each other. In addition, since the platform 124 is connected to the support 140 having a load, the receiving grooves (111, 111 ') is so that the platform 124 does not fall below a certain height by the load of the support (140, 140'). It acts as a limiting stopper.

The elevator 120 having the above-described configuration rotates the nut 122 around the lifting platform 124 and the fixed screw 123 which are not rotated by the supporting members 140 and 140 ', so that the screw 123 is the nut. Linear movement in the vertical direction in accordance with the rotation direction of (122), this linear movement of the lifting platform 124 will raise and lower the support (140, 140 ').

The support (140, 140 ') is in the shape of a rod arranged side by side along the longitudinal direction of the buried pipe 110, the upper end is connected to the elevator 120, respectively.

Rotating body (130, 130 ', 130 "; hereinafter 130) is disposed at regular intervals along the support (140, 140'), rotatably fixed via the connecting shaft 141, buried pipe 110 and The pivot shaft 131 is fixed via the pivot shaft 131. That is, when the supports 140 and 140 'move up and down, the pivot body 130 having one end fixed via the coupling shaft 141 moves the pivot shaft 131. It is to rotate to the center.

On the other hand, the rotating body 130, 130 'disposed on each of the support (140, 140') are alternately arranged to face each other as shown in Figs. Therefore, the tension cable 114a inserted into the passage 112 and drawn out to the outlet 113 is engaged with the other end of the rotating body 130 one by one, and is zigzag by a plurality of rotating bodies 130 arranged alternately. Will be wired.

As a result, the common lighting fixture mounting apparatus 100 for lighting according to the present invention can accommodate the tension cable 114a having a length longer than that of the buried pipe 110 by arranging the tension cable 114a in a zigzag form.

For reference, if the platform 124 is located at the lowermost end by driving the elevator 120, the platform 124 pushes the support 140 downward while horizontally rotating the plurality of rotating bodies 130, 130 ', 130 ". Rotating members 130, 130 ', 130 ", which are arranged horizontally, alternately, will forcibly bend the tension cable 114a in a zigzag fashion.

On the other hand, as shown in FIG. 2, if a problem occurs in the lighting means 173 and the elevator 120 is driven, and the platform 124 is positioned at the top by such driving, the platform 124 is the support 140. Pulling upward one end of the rotating body 130 while pulling upward, through which the other end of the rotating body 130 will be inclined downward. Of course, since the tension cable 114a is no longer supported by the rotating body 130, it will fall by the weight of the lighting member 170.

Therefore, the manager can visually check the state of the lighting member 170 stretched downward and easily recognize that a problem has occurred.

Of course, if the manager solves the problem occurring in the lighting member 170 through the maintenance work, the elevator 120 moves the lifting platform 124 downwards, the lifting platform 124 thus moved to the support 140 downward The pivoting body 130 will rotate by moving. As a result, the tension cable 114a is again arranged in a zigzag form, and the tension cable 114a is bent and supported by the pivoting body 130 arranged in a zigzag form, and pulled downward through the guide roller 116. The end of the tension cable 114a is finally introduced into the buried pipe 110 is trimmed. In addition, the lighting member 170 connected to the tension cable 114a will also move upward and be seated in place.

On the other hand, the mounting table according to the present invention further includes a winding roller (117, 117 ') for supporting the lighting member 170 via the rope (117a). The take-up rollers 117 and 117 'are intended to be rotated in one direction by a torsion spring like a spring. The ropes 117a are connected in a direction opposite to the rotational direction to receive tension, and the ropes 117a are illuminated. Is connected to the member 170. That is, when the illumination member 170 falls, the winding rollers 117 and 117 'are rotated in the reverse direction in the direction in which the coiling occurs by the load, and the rope 117a is unwound, and when the illumination member 170 is elevated again, the winding is performed. The rollers 117 and 117 'wind up the rope 117a again. At this time, the winding force of the winding rollers 117 and 117 'shares the burden of the rotating body 130 which should raise and lower the lighting member 170, and the lighting member 170 smoothly by the rotation of the rotating body 130. Ascend and engage the buried pipe (110).

Unexplained withdrawal number "171" is a "lighting case" to wrap and protect the lighting means 173, unexplained withdrawal number "172" is a "ring" for connecting the rope 117a with the light case (171).

Figure 3 is an exploded perspective view showing the assembled state of the rotating body and the support according to the present invention, will be described with reference to this.

As described above, the other end of the rotating body 130 adjusts the arrangement state of the tension cable 114a while rotating in accordance with the operation of the elevator (120). That is, when the platform 124 moves downward by the operation of the elevator 120, the rotating body 130 is horizontally arranged while bending and accommodating the tension cable 114a in a zigzag form, and the platform 124 moves upward. While the body 130 is inclined downward, the tension cable 114a is no longer supported, and at the same time, the illumination member 170 is dropped downward.

However, the supports 140 and 140 'move in the horizontal direction together with the upward movement. This is because the supports 140 and 140 'interlock along a moving path of one end of the rotating body 130 rotating around the rotating shaft 131. Therefore, in order to smoothly bond the lifting platform 124 moving up and down in the elevator 120 and the support bases 140 and 140 'moving horizontally as well as the shanghai, the lifting platform 124 is the support base 140 and 140'. The movement path 124a corresponding to the horizontal movement path of the upper side of the support (140, 140 ') is connected to the platform 124, the locking step 142 is engaged with the movement path (124a) Is formed. That is, the locking jaw 142 binds the supports 140 and 140 'and the platform 124 so that the upper ends of the supports 140 and 140' inserted into the movement path 124a are movable without being separated from each other. . Of course, the movement path (124a) it will be obvious that the jaw that the locking jaw 142 is to be formed.

Meanwhile, the other end of the pivot 130 further includes a pulley 133. The pulley 133 is installed to rotate along the direction of movement of the tension cable 114a at the other end of the pivot 130, and is engaged between the pivot 130 and the tension cable 114a when engaged with the tension cable 114a. Minimize sliding friction. That is, the tensioning cable 114a which contacts when the rotating body 130 rotates naturally slides along the other end of the rotating body 130 so that the operation of the rotating body 130 is smooth.

To this end, the other end of the rotating body 130 is formed with a rotary groove 132 into which the pulley 133 is inserted, and the pulley 133 inserted into the rotary groove 132 is rotatable via the rotating shaft 134. It is fixed, and the circumference of the pulley 133 will be exposed to the outside for engagement with the extension (30).

4 is a circuit diagram schematically showing the electrical connection state of the lighting means according to the present invention, will be described with reference to this.

The present invention is to be able to notify the outside that the problem occurred by the lifting and lowering of the lighting member 170 according to the problem of the lighting member 170, the problem of the lighting member 170 is a problem in the lighting means 173 It means that there is. Therefore, the controller 180 for detecting the problem of the luminaire 173 and controlling the elevator 120 includes a resistor module 182 for measuring a resistance value of the luminaire 173 and a current value flowing through the current circuit. Check the measured values of the current module 183 and the resistance module 182 and the current module 183 to compare with the normal value and if a difference occurs, the lighting means 173 is considered to have a problem and the elevator The controller 180 further includes a control module 181 for driving the 120.

Here, the control module 181 and the elevator 120 are connected in parallel with the lighting means 173, the control module 181, the elevator 120 and the lighting means 173 is controlled by one switch 40. .

That is, if no problem occurs in the luminaire 173, the manager may control the luminaire 173 through the operation of the switch 40, and the luminaire 173 may have a problem when the switch 40 is turned on. When is generated, the elevator 120 is operated regardless of whether or not disconnection caused by breakage of the lighting means 173. Of course, if the switch 40 is in the off state, the operation of the elevator 120 will be stopped regardless of whether or not there is a problem with the luminaire 173.

FIG. 5 is an exploded perspective view illustrating an electrical connection between the common light fixture and the extension tube according to the present invention, and FIG. 6 is a cross-sectional view of FIG. 5.

The buried pipe 110 according to the present invention is not required to wire the extension 30 separately from the installation of the common light fixture 100, when the common light fixture 100 is buried, as well as physical buried in the buried pipe 110 The electrical connection between the internal line 30 to be wired and the internal line 30 'to the internal tube 20 can also be made naturally, thereby greatly reducing the process of power distribution construction.

To this end, the common lamp mounting stand 100 according to the present invention further includes a cap 150 covering an upper end of the buried pipe 110. The cap 150 has a terminal 151 that is electrically connected to the internal line 30 wired to the buried pipe 110, the terminal 151 forms a rigid bar shape, such as the terminal of the plug. Of course, the terminal 151 is a conductor that is energized with the extension (30).

Meanwhile, another extension line 30 'electrically connected to the extension line 30 wired to the common lamp mounting stand 100 is connected via the connector 160.

The connector 160 includes a base 161 formed in the inner tube 20 embedded in the ceiling 10, a door 162 rotatably disposed in front of the base 161, and a base 161. Is rotatably disposed on the front is a connection block 163 detachable with the cap 150. Here, the door 162 and the connection block 163 to rotate independently of each other, will be described in detail below.

The base 161 has a rotating groove 161a for accommodating the door 162 and the connection block 163 so as to rotate in turn, and the terminal 151 provided in the cap 150 is inserted into the rotating groove 161a. Terminal contact portion 161b is provided. As described above, since the door 162 and the connection block 163 rotate in the rotary groove 161a, the rotary groove 161a should be formed in such a manner as not to interfere with their rotation. It is preferable to form a circle together.

On the other hand, the terminal contact portion 161b is provided with a conductor that conducts electricity to the internal wire 30 'wired to the inner tube 20, and the terminal 151 inserted into the terminal contact portion 161b is electrically connected to the conductor. Connected. As a result, the common light fixture 100 and the inner tube 20 are electrically connected to each other by the coupling of the cap 150 and the connector 160.

The door 162 opens and closes the terminal contact portion 161b which is opened forward while rotating about the center groove 161c of the base 161. The door 162 is fixed through the torsion spring 162a and is shot in one direction. That is, if no external force is applied to the door 162, the door 162 is fixed at the position covering the terminal contact portion 161b, and when the external force is applied, the door 162 rotates by the external force to open the terminal contact portion 161b. Of course, when the external force disappears, the door 162 will be returned by the torsion spring 162a to close the terminal contact portion 161b again.

The connection block 163 is composed of a guide 163a rotatably engaged with the rotary groove 161a, and a connector 163e with which the cap 150 is engaged.

The guide 163a is formed with a through hole 163b through which the terminal 151 passes.

The connector 163e is fixed to the guide 163a, rotates with the rotation of the guide 163a, and has a terminal groove 163g through which the terminal 151 penetrates. In addition, in order to maintain a stable engagement with the cap 150, the cap 150 may further include a connecting groove 163f.

That is, the cap 150 is engaged with the connection groove 163f, and the terminal 151 provided in the cap 150 sequentially penetrates through the terminal groove 163g and the through hole 163b to the terminal contact portion 161b. While being fitted, it is in contact with a conductor built in the terminal contact portion 161b.

As described above, since the door 162 and the connection block 163 rotate independently from each other in the rotary groove 161a, the rotation center 163c fixing the connection block 163 interferes with the door 162. A through portion 163d having a narrow diameter may be formed so as not to penetrate.

7 is a view schematically showing the operation of the connector according to the present invention, Figure 8 is a view showing a state in which the terminal contact portion of the connector according to the present invention is closed, with reference to this operation of the connector 160 The wiring structure using the common lamp mounting stand 100 according to the present invention will be described in detail.

As shown in Fig. 7A, the terminal contact portion 161b is closed when the door 162 is not subjected to an external force. Therefore, regardless of the position of the connection block 163, the terminal contact portion 161b is always kept closed.

In order for the worker to electrically connect the common light fixture 100 and the extension tube 20, the terminal 151 of the cap 150 is connected to the terminal groove 163g and the through hole (as shown in FIG. 7 (b)). 163b), then rotate counterclockwise.

The terminal 151 is rotated while applying an external force to the side of the door 162, the terminal contact portion 161b is opened by the rotation of the door 162. That is, the terminal 151 may be inserted into the opened terminal contact portion 161b.

Then, when the operator separates the terminal 151 from the terminal contact portion 161b for the management and maintenance of the extension 30, the door 162 is reversely rotated by the repulsive force of the torsion spring 162a as shown in FIG. As described above, the terminal contact portion 161b is closed again.

Of course, in order for the operator to connect the terminal 151 to the terminal contact portion 161b, the terminal 151 is inserted into the terminal groove 163g and the through hole 163b, and then rotated to apply an external force to the door 162 laterally. The door 162 subjected to the external force rotates to open the terminal contact portion 161b.

This process not only draws attention to the worker who is working, but also prevents various accidents that may occur while the terminal contact portion 161b where the conductor is exposed is exposed as it is.

In addition, once the wiring work is completed, the common lamp fixture 100 and the inner tube 20 is embedded in the ceiling 10, if the terminal contact portion 161b is exposed without any action, the terminal contact portion 161b Through short-circuit and short-circuit short-circuit material may be introduced to increase the probability of an electrical safety accident, the connector 160 minimizes this risk.
