Referring to Figures 1 and 2, the present invention is a combination between the lamp pole 20, the lamp and / or other light-emitting device installed on the ground, the lamp 10 and the lamp pole 20 And a coupling member 100 to be fixed.

Here, the luminaire 10 includes a lighting fixture 11 to which a plurality of LEDs or lamps are fixed to the inside, and a fastening part that extends rearward from the lighting fixture 11 and is fastened to the tip 21 of the lamppost 20 ( 12).

The contour fixing part 11 forms a reflective surface on the inner surface, a lamp or a plurality of LEDs is fixed in the center, and is directed to the ground or at a set angle.

The fastening portion 12 extends to the rear of the contour fixing portion 11 and is formed in a pipe shape having an empty space so that electric wires can be guided therein.

The front end 21 of the lamp column 20 is formed in an empty space inside so that an electric wire extending to the lamp 10 can be guided inside, and is formed in a pipe shape that is introduced into the fastening part 12. Here, the front end 21 of the lamp column 20 is formed with a plurality of fastening holes 22 to which the fixing bolts 140 of the lamp 10 to be described later are fastened.

The coupling member 100 supports the fixing bolt with an elastic force on the front end 21 of the lamp post 20 at the fastening part 12 extended from the lamp post 11 and presses the lamp post 10 to be coupled to the lamp post 20 However, it is configured to be fastened without a separate bolt assembly process. This will be described in more detail with reference to FIGS. 3 and 4.

3 is a cross-sectional view illustrating a coupling member, and FIGS. 4 and 5 are views showing an embodiment of a fitting hole.

3 to 5, the coupling member 100 protrudes upward from the outer surface of the fastening part 12, the support block 120 forming a space in which a through hole is formed, and the inner side of the support block 120 The front end of the fastening part 12 and the lamp post 20 by the pressing force by the cover part 110 to seal the space, the pressing part 150 protruding downward from the inner surface of the cover part 110, and the pressing part 150 It includes a fixing bolt 140 fastened to the fastening hole 22 formed in (21), and an elastic portion 130 for elastically supporting the fixing bolt 140.

The support block 120 protrudes from the outer surface of the fastening part 12, and forms an inner empty space in which the fixing bolt 140 to the elastic part 130 are installed. Here, the support block 120 has a support end 121 upward from the outer surface and a fitting hole 122 downward from the support end 121.

The support end 121 supports the cover part 110 by forming a wall surface protruding upward from the center of the through hole 13 penetrating from the outer surface of the fastening part 12. Here, the upper surface of the support end 121 is formed with a downward fitting hole 122.

The fitting hole 122 may be formed of a screw thread or a protruding protrusion, as shown in FIG. 4, on the inner surface so that the cover portion 110 is inserted in a stepwise manner.

Alternatively, as shown in FIG. 5, the fitting hole 122 may have a concave surface or a convex surface sequentially formed from the inner surface to match the joint shape of the fitting protrusion 113 to be described later. That is, in the fitting hole 122, concave surfaces in which the first and

second nodes

113a and 113b are matched are sequentially formed.

The cover part 110 includes a first cover 111 that is forcefully fastened from the upper surface of the support end 121, a second cover 112 that is screwed with the first cover 111, and a first cover ( 111) includes a fitting protrusion 113 that extends downward from the lower surface of the fitting hole 122 and is forcibly fastened to the fitting hole 122, and a fixing screw for coupling the first cover 111 and the second cover 112 to each other.

The first cover 111 seals the open upper surface of the support end 121 while the second cover 112 is fixed by a fixing screw.

The fitting protrusion 113 protrudes downward from the lower surface of the first cover 111 and is inserted into the fitting hole 122 by force fitting. To this end, the fitting protrusion 113 is a convex shape and is manufactured in a shape in which a plurality of nodes forming an oval-shaped outer surface extending outwardly form a node and extend in sequence.

For example, the fitting protrusion 113 is formed of a first node 113a and a second node 113b, and has a smaller diameter between the first node 113a and the second node 113b.

Therefore, the operator inserts the first node 113a into the fitting hole 122, and then the tip 21 of the lamp post 20 is brought into the inside of the lamp 10 to reach a predetermined position, and the fixing bolt 140 is When reaching a position capable of communicating with both the fastening hole 22 and the through hole 13 is inserted into the fitting hole 122 up to the second node 113b. A more detailed description will be given later.

The second cover 112 is coupled to the first cover 111 by a fixing screw 114 to seal the upper portion of the support block 120. Here, the second cover 112 is separated from the first cover 111 when the fixing screw 114 is released. In addition, since the pressing unit 150 is integrally formed with the second cover 112, when the second cover 112 is separated, the pressing against the fixing bolt 140 is released.

That is, when the second cover 112 releases the fixing bolt 140 after opening the upper surface of the support block 120 or releases the pressing force to release the coupling between the fastening part 12 and the lamp column 20 Open.

In addition, the cover unit 110 may further include a partition wall 115 extending downward to partition spaces in which the pressing unit 150 is formed.

The partition wall 115 may be downward from the lower surface of the second cover 112 and may be spaced apart from each other to partition a plurality of spaces in which the pressing portion 150 is formed therebetween. Alternatively, the partition wall 115 may be formed upright on the outer surface of the fastening part 12.

The pressing part 150 protrudes downward from the lower surface of the second cover 112 to support the elastic part 130 at the outer surface, and press the fixing bolt 140 at the lower end. For example, the pressing part 150 supports the elastic part 130 fitted on the outer surface in a state in which the cover part 110 is firstly fitted with the first joint 113a, but the cover part 110 is secondarily removed. When the 2nd node (113b) is inserted, it comes into contact with the fixing head 141 of the fixing bolt 140 which is in communication with the through hole 13 of the fastening part 12 and the fastening hole 22 of the tip 21 of the lamp column 20 And pressurize.

In addition, the pressing unit 150 may be fitted with the elastic unit 130 on the outer surface or may be adhesively fixed to the elastic unit 130 by welding, as in other embodiments described later.

The fixing bolt 140 is a rod body 142 communicating with the through hole 13 of the fastening part 12 and the fastening hole 22 formed in the tip 21 of the lamp post 20, and the outer surface of the fastening part 12 It includes a fixed head 141 that is caught on.

The rod body 142 is a tip type 142a whose diameter gradually decreases, not a downwardly inclined surface (see FIGS. 9 and 10) or a downwardly inclined surface 142a in the direction in which the tip 21 of the lamp column 20 is retracted. ) (See FIG. 6).

Here, the downwardly inclined surface 142a is installed in a fixed state so that the fixing bolt 140 is not rotated, and is for receiving a force to lift the fixing bolt 140 when the end of the drawn tip 21 contacts.

The fixed head 141 is formed to expand in diameter in the lateral direction on the upper portion of the rod body 142 and is caught on the outer surface of the through hole 13. Here, the fixed head 141 is in direct contact with the lower end of the pressing portion 150 and the elastic portion 130. For example, the fixed head 141 may be formed integrally with the elastic part 130 and/or the pressing part 150 or may be formed in a mutually independent structure.

The elastic part 130 is, for example, a helical spring fitted to the outer surface of the pressing part 150 and elastically presses the fixing head 141 of the fixing bolt 140. For example, the fixing bolt 140 is moved upward when the tip 21 of the lamp column 20 is inserted, and the elastic portion 130 is contracted. And when the fixing bolt 140 reaches the fastening hole 22 of the lamp column 20, it is lowered again.

That is, when the fixing bolt 140 is positioned in the fastening hole 22 and the through hole 13 after lifting, the elastic part 130 elastically supports it to descend again.

Here, the fixing bolt 140 maintains a state spaced apart from the pressing part 150 in a state in which the fitting protrusion 113 of the first cover 111 is inserted into the fitting hole 122 only with the first joint 113a, It is in contact only with the elastic part 130. And the fixing bolt 140 is fixed by the pressing portion 150 when the fitting protrusion 113 of the first cover 111 is inserted into the fitting hole 122 up to the second joint 113b. In addition, when the second cover 112 is separated, the fixing bolt 140 is released from the pressing force by the pressing unit 150 and may be pulled out through the upper surface of the open support block 120.

The present invention includes the above configuration, and will be described below with reference to FIGS. 6 to 8 achieved through the above configuration.

6 and 7, the operator pulls in the front end 21 of the lamp post 20 inside the fastening part 12 of the lamp 10. At this time, the first cover 111 and the second cover 112 are in a state of being coupled by the fixing screw 114, and the fitting protrusion 113 is a state in which only the first joint 113a is inserted into the fitting hole 122 to be. Therefore, the pressing part 150 maintains a state spaced apart from the fixing head 141 of the fixing bolt 140, and the elastic part 130 is inserted into the outer surface of the pressing part 150, and the fixing head 141 is Elastic support.

In addition, the fixing bolt 140 is in a state in which the rod body 142 is inserted into the through hole 13 of the fastening part 12, and the fixing head 141 is in a state that is caught on the inner bottom surface of the support block 120. .

Therefore, when the first fixing bolt 140 is pressed while the front end 21 of the lamp column 20 is drawn in, it is raised and lowered by the force. And the first fixing bolt 140 is lowered when the first fastening hole 22 is positioned at the lower side while the lamp post 20 is continuously inserted, but is raised and lowered again as the lamp post 20 continues to move.

In the luminaire 10, for example, if there are three fixing bolts 140 and three fastening holes 22, until all three fixing bolts 140 are inserted into the three fastening holes 22 Keep moving. The fixing bolt 140 may generate a hitting sound while communicating the through hole 13 and the fastening hole 22 while raising and lowering the elastic force by the elastic part 130 and then descending. Therefore, it can be recognized that the entire fastening hole 22 and the fixing bolt 140 are placed in the correct position through the number of times the worker's hitting sound is heard.

Then, the operator strikes the cover part 110 so that the fitting protrusion 113 is completely inserted into the fitting hole 122. Accordingly, the pressing unit 150 presses the fixed head 141 while the fitting protrusion 113 is completely inserted into the fitting hole 122. Therefore, the fixing bolt 140 communicates the through hole 13 of the lamp 10 and the fastening hole 22 of the lamp column 20 to mutually couple.

In addition, the luminaire 10 and the lamp post 20 assembled as above can be simply disassembled by separating the cover part 110. This will be described with reference to FIG. 8.

Referring to FIG. 8, in the present invention, the operator removes the second cover 112 from the first cover 111 by releasing the fixing screw 114. Accordingly, as the second cover 112 is separated, the fixing bolt 140 whose pressurized state is released from the inside of the support block 120 may be exposed.

Therefore, the operator can separate the light fixture 10 from the lamp post 20 after separating the open support block 120 from the through hole 13 and the fastening hole 22 through the fixing bolt 140 through the upper surface.

That is, in the present invention, there is no process in which the operator accompanies physical force in the assembly and disassembly process, and the coupling and disassembly between the luminaire 10 and the lamppost 20 is possible by a simple operation of hitting or separating the cover part 110. Compared to the prior art, the operation is very easy and can be performed in a short time.

In addition, the present invention may include an embodiment in which the elastic part 130, the cover part 110, and the fixing bolt 140 are integrally configured.

9 and 10 are views showing another embodiment of the present invention.

9 and 10, in another embodiment of the present invention, the cover part 110, the elastic part 130, and the fixing bolt 140 are integrally configured.

That is, the elastic portion 130 is fixed to the lower surface of the second cover 112 in the cover portion 110 by welding, and the elastic portion 130 is fixed to the fixing head 141 of the fixing bolt 140 by welding. . At this time, since the fixing bolt 140 is fixed to the elastic part 130, it is not rotated in the through hole 13 and the fastening hole 22. Accordingly, the fixing bolt 140 may form an inclined surface 142a in the direction in which the tip 21 of the lamp column 20 is retracted from the rod body 142.

In such a structure, when the tip 21 of the lamp column 20 is drawn in with a strong force, a force is applied to the inclined surface 142a of the fixing bolt 140 so that the fixing bolt 140 is raised and lowered, and the position of the fastening hole 22 Descends from Therefore, by repeating this process, the entire fixing bolt 140 may be fastened to a predetermined position.

In addition, another embodiment as described above is a fitting protrusion consisting of the first cover 111 and the second cover 112, the first joint (113a) and the second joint (113b) fixed by the fixing screw 114 ( 113) and the support block 120 including the fitting hole 122 may be selectively applied, and the pressing part 150 may also be configured in that the elastic part 130 forms a guide and a contact area. Alternatively, the pressing unit 150 may be omitted.

The embodiments of the present invention described above are merely exemplary, and those of ordinary skill in the art to which the present invention pertains will appreciate that various modifications and other equivalent embodiments are possible.
