Description

Luminaire Mounting Device}

The present invention relates to a lighting fixture mounting device. More specifically, the present invention relates to a lighting fixture mounting device that allows lighting fixtures to be installed in close contact with or removed from the ceiling.

Referring to the drawing of Patent Document 1, the reaction force means of Patent Document 1 provides an elastic reaction force in a direction that prevents the latch bundle from being retracted when the free end of the latch bundle is spread, and the latch bundle retracts. When the reaction force means is deformed beyond the elastic deformation threshold, the reaction force means provides elastic repulsion in a direction to prevent the latch assembly from opening again, which has the effect of preventing lifting between the ceiling surface and the lighting fixture.

Referring to the drawing of Patent Document 2, similarly, the reaction force means of Patent Document 2 provides an elastic reaction force in a direction that prevents the clasp member from being retracted when the free end of the clasp member is spread, and the clasp member retracts. When the reaction force means is deformed beyond the elastic deformation threshold, the reaction force means provides elastic reaction force in a direction to prevent the latch member from opening again, which has the effect of preventing lifting between the ceiling surface and the lighting fixture. .

Meanwhile, the thickness of lighting fixtures has recently become thinner, but the lighting fixture installation structure of Patent Document 1 requires a thickness greater than a certain thickness to provide appropriate support to the lighting fixture due to its mechanism, so the lighting fixture is installed at a thickness thinner than that. It has the problem of being difficult to use.

In addition, in Patent Document 1, the reaction force means is arranged parallel to the direction of the rotation axis of the latch assembly, so when the latch assembly rotates, stress is concentrated on the edge close to the rotation axis of the reaction force means, and this concentration of stress is used to restore the reaction force means. There is a problem that elasticity can be reduced or, in severe cases, lost. Similarly, in Patent Document 2, the reaction force means is arranged parallel to the direction of the rotation axis of the latch member, so when the latch member rotates, stress is concentrated on the edge close to the rotation axis of the reaction force means, and this concentration of stress is the restoring elasticity of the reaction force means. There is a problem that it can deteriorate or, in severe cases, lose it.

In addition, in Patent Document 1, when the free end of the latch assembly is over-rotated in the direction away from the base bracket portion, a force is applied to both ends of the reaction force unit by the latch assembly to the opposite side of the base bracket portion, and thus the coupling of the reaction force means is released. There is a problem that could happen. Likewise, in Patent Document 2, when the free end of the latch member overrotates in a direction away from the base bracket, a force pushing the reaction means to the opposite side of the base bracket is applied to both ends of the reaction means by the latch member, and thus the coupling of the reaction means can be released. There is a problem.

In addition, in Patent Document 2, the expansion wings prevent the intermittent protrusions from being inserted deeper than intended into the entry groove, but the expansion wings are formed on the plane where the reaction force means are arranged, so over-insertion of the intermittent protrusions is clearly prevented. The problem is that you can't do it.

<First coupling portion (100)>

Referring to Figures 1 to 3, in the lighting fixture mounting device according to an embodiment of the present invention, the first coupling portion 100 includes a frame 120 and an intermittent bracket 110.

The frame 120 may have an approximately rectangular shape, but the shape of the frame 120 is not limited thereto. For example, a circular frame 120 may be adopted to mount a circular lighting fixture.

A lighting fixture may be coupled to the frame 120. The frame 120 according to an embodiment of the present invention can have a height of 10 mm or less, so when mounting a slim lighting fixture, the lighting fixture is installed on the ceiling while preventing the lighting fixture from protruding further from the ceiling than the height of the lighting fixture itself. It can be installed on.

The lighting fixture and the first coupling portion 100 can be coupled by screwing the edge of the steel panel 12 to the frame 120. A lighting fixture that can be mounted on or separated from the ceiling using the present invention may include, for example, a steel panel 12 and a light source (not shown) covered with the steel panel 12.

An intermittent bracket 110 for coupling the lighting fixture to the second coupling part 200 via the first coupling part 100 may be screwed to the inner edge of the frame 120. Here, at least some of the screw fastening points of the intermittent bracket 110 and at least some of the screw fastening points of the steel panel 12 may be the same.

The distal end of the pivoting base 220 of the second coupling portion 200, which will be described later, may be fitted into the concave groove 111 of the intermittent bracket 110. The recessed groove 111 is formed to extend horizontally by a predetermined length longer than the horizontal length of the pivoting base 220 so that the pivoting base 220 can slide in the horizontal direction for a certain period while being inserted into the intermittent bracket 110. You can.

In one embodiment of the present invention, at least some of the intermittent brackets 110 have an entry groove communicating with the concave groove 111 so that the rotating base 220 can enter the vertical direction and be inserted into the intermittent bracket 110 ( 112). The entry groove 112 may extend from one end of the concave groove 111 in the horizontal direction. According to this structure of the intermittent bracket 110, the rotating base 220 is inserted into the intermittent bracket 110 in the vertical direction through the entry groove 112 and then slid in the horizontal direction, so that the rotating base 220 is vertically connected to the intermittent bracket 110. It is possible to prevent deviation from (110). A pair of intermittent brackets 110 are installed on two sides of the frame 120, and among these, only one pair of intermittent brackets 110 has an entry groove 112.

1 to 6, the fixed base 210 may include a plurality of support plates 211 to which the pivoting base 220 is coupled and a connection plate 213 connecting the plurality of support plates 211. there is. However, the configuration of the fixed base 210 is not particularly limited as long as it is coupled with the rotating base 220. A plurality of screw fastening holes 211b are drilled in the support plate 211 and/or the connection plate 213. The screw fastening holes 211b are formed to screw the fixing base 210 to the ceiling and can be drilled in the form of long holes, and their direction and number are not particularly limited. A portion of the support plate 211 and a portion of the connection plate 213 are disposed overlapping each other, and the support plate 211 has a standing portion 211c protruding from one surface of the support plate 211 and a standing portion on the connection plate 213. An insertion hole may be drilled at a position corresponding to the position of the portion 211c. The worker can easily couple the support plate 211 and the connection plate 213 without a separate coupling device by inserting the standing part 211c into the insertion hole and then bending the standing part 211c. Here, the standing portion 211c may be formed by punching a portion of the support plate 211 and then bending it. According to this embodiment, there is an advantage that the support plate 211 and the connection plate 213 can be easily combined and the cost of the coupling mechanism can be reduced. However, the connection method of the support plate 211 and the connection plate 213 is not limited to this embodiment, as they may be joined by welding or the like.

In one embodiment, each of the pair of support plates 211 is disposed adjacent to the side of the corresponding frame. A pair of rotating bases 220 are coupled to each support plate 211. Each rotating base 220 is arranged so that one end thereof faces the corresponding fixing bracket 110. The support plate 211 includes a hinge holder 211a to which the rotating base 220 is rotatably coupled. The hinge holder 211a may be formed by punching and bending a portion of the support plate 211.

The number and location of the rotating bases 220 correspond to the number and location of the intermittent brackets 110. In one embodiment, the first coupling part 100 has four intermittent brackets 110, and the second coupling part 200 has four rotating bases 220, but the intermittent brackets 110 and the rotating base 220 The number is not limited to this. A pair of support plates 211 are coupled to each other by the connection plate 213, and a pair of rotation bases 220 are coupled to each support plate 211, so that the two pairs of rotation bases 220 are connected to a connection plate ( 213) and can be handled and managed as a whole by being interconnected.

In one embodiment, the rotating base 220 has a base plate 225 with a through hole 224 formed, and a pair of hinge protrusions 221 rotatably fitted to the hinge holder 211a are formed on the base plate 225. ) is formed protruding from. An intermittent protrusion 222 fitted into the recessed groove 111 of the intermittent bracket 110 protrudes from the rotating end of the base plate 225. However, the configuration of the rotating base and the arrangement of its components are not limited to this embodiment.

In one embodiment, the base plate 225 is arranged so that its width direction is parallel to the width direction of the concave groove 111, and the width of the base plate 225 is wider than the width of the concave groove 111. Therefore, the base plate 225 may not be overinserted into the concave groove 111. In order to more thoroughly prevent the base plate 225 from being over-inserted into the concave groove 111, the rotating base 220 is erected on the opposite side of the fixed base from both edges perpendicular to the width direction of the base plate 225. It may have a hanging wing (223).

Both ends of the reaction force fixing unit 232 are coupled to the fixing base 210 to form a closed curve into which the elastic member 231 is inserted together with the fixing base 210. In one embodiment, the reaction force fixing part 232 is approximately “ㄷ” shaped and both ends are coupled to the fixing base 210. Here, the fact that the reaction force fixing part 232 is coupled to the fixed base 210 includes the case where the reaction force fixing part 232 and the fixed base 210 are formed as one piece and are coupled to each other. The reaction force fixing part 232 may be formed by punching and then bending a portion of the fixing base 210. This manufacturing method can reduce the cost and processing difficulty of the product. The reaction force fixing part 232 penetrates the through hole 224. When the rotating base 220 is overlapped with the fixed base 210, the reaction force fixing part 232 protrudes through the through hole 224 of the rotating base 220.

Referring to Figure 5, at least a portion of the reaction force fixing part 232 is disposed on the opposite side of the fixing base 210 of the elastic member 231. While the reaction force fixing part 232 is coupled to the fixed base 210 and does not move, the elastic member 231 inserted into the reaction force fixing part 232 is fixed to the reaction force fixing part 232 together with the rotating base 220. It can rotate within the insertion hole formed by the base 210. Here, the rotation range of the elastic member 231 is limited by the reaction force fixing portion 232.

In one embodiment, the elastic member 231 is a plate-shaped spring extending in one direction, and one end and the other end in the extending direction are disposed perpendicular to the rotation axis of the rotating base 220, and the fixed base of the rotating base 220 ( 210) It is joined to the opposite side. The elastic member 231 is inserted into the closed curve formed by the reaction force fixing part 232 and the fixing base 210. When the elastic member 231 is in the second state convex to the opposite side of the fixed base 210, the fixed base 210 presses the elastic member 231 toward the fixed base 210 to rotate the elastic member 231 and its coupled member. The base 220 is brought into close contact with the fixed base 210. The fixed base 210 may be disposed at approximately the midpoint of the longitudinal direction of the elastic member 231 in a direction transverse to the longitudinal direction of the elastic member 231 . According to this configuration, when the free end of the rotating base 220 rotates in a direction away from the fixed base 210, stress is not concentrated on one corner of the elastic member 231, thereby preventing deformation and damage of the elastic member 231. can do. In addition, even when the free end of the pivoting base 220 overrotates in a direction away from the fixed base 210, no force in the direction opposite to the pivoting base 220 is applied to both ends of the elastic member 231. ) is not easily disengaged from the rotating base 220.

When the elastic member 231 is in the first state, the rotating base 220 is spread apart with respect to the fixed base 210, and when the worker rotates the rotating base 220 toward the fixed base 210, the elastic member 231 As it is deformed to be convexly flipped toward the fixed base 210, the reaction force applied by the reaction force fixing part 232 to the elastic force of the elastic member 231 causes the elastic member 231 and the rotating base 220 to be connected to the fixed base 210. It acts to push to the side. That is, the elastic member 231 provides a repulsive force to prevent the rotation base 220 from being retracted by a certain elastic force when the rotation base 220 is open, and when an external force exceeding the elastic threshold is forcibly applied to the rotation base 220. The repulsive force is reversed, so that a reactive force acts in the opposite direction to prevent the rotating base 220 from opening.

Hereinafter, a process of mounting a lighting fixture to the ceiling using a lighting fixture mounting device according to an embodiment of the present invention will be described.

The second coupling portion 200 is installed on the ceiling. The elastic member 231 of the second coupling portion 200 is convex toward the fixed base 210, and the rotating base 220 is opened toward the floor.

Afterwards, the worker connects the first coupling part 100 with the lighting device to the second coupling part 200. The safety ring 130 provided on the first coupling part 100 is tied to the ceiling to prevent a fall accident. Proceed with work while preventing damage.

Figure 7 is a perspective view showing one side of the intermittent protrusion fitted into the corresponding intermittent bracket according to an embodiment of the present invention.

Referring to FIG. 7, after fastening the safety ring 130, the operator attaches the intermittent protrusion 222 of the second coupling portion 200 to the two intermittent brackets 110 provided on one side of the first coupling portion 100. Make sure it is inserted. Here, the intermittent bracket 110 into which the intermittent protrusion 222 is inserted is the intermittent bracket 110 on the side in which only the concave groove 111 is formed without the entry groove 112.

Figure 8 is a perspective view showing the other intermittent protrusion of Fig. 7 fitted into the corresponding intermittent bracket. Figure 9 is a perspective view showing the interrupted protrusion of Figure 8 sliding within the concave groove 111.

Referring to FIGS. 8 and 9, the worker then inserts the intermittent protrusion 222 in a vertical direction into the entry groove 112 of the remaining intermittent bracket 110 of the first coupling portion 100. (222) is slid to move along the concave groove 111 to confirm the installation position of the lighting fixture.

Thereafter, when an external force is applied by pushing the lighting fixture toward the ceiling, the rotating base 220 is folded toward the ceiling and retracted toward the fixed base 210 due to the external force, and the deformation direction of the elastic member 231 is reversed to form the elastic member ( 231) is convexly deformed to the opposite side of the fixing base 210, and the first coupling part 100 is adhered to and fixed to the ceiling by the reaction force applied by the reaction force fixing part 232 to the elastic member 231.

The present invention as described above allows lighting fixtures to be easily and quickly mounted or removed in close contact with the ceiling by using the one-touch operation method of the lighting fixture mounting device.

In addition, the present invention allows the adhesion mechanism 230 to operate by pressing and pushing the lighting fixture at a position opposite the base bracket after coupling the second coupling portion 200 to the ceiling, thereby facilitating installation of the lighting fixture. do.

In addition, when the pivoting base 220 of the present invention is in an open state, the elastic member 231 provides a repulsive force that prevents the pivoting base 220 from collapsing due to a certain elastic force, and provides a repulsive force to the pivoting base 220 to prevent the pivoting base 220 from collapsing. When a force exceeding the elastic threshold is applied, an elastic force in the opposite direction is applied to provide a repulsive force that pulls the pivoting base 220 so that the pivoting base 220 does not open, thereby preventing a gap between the ceiling and the lighting fixture and improving the appearance. Not only is it beautiful, but the structure of the lighting fixture mounting device is slim, which creates more space inside the frame 120, making it possible to install lighting fixtures of various thicknesses.

In addition, in the present invention, even when the free end of the rotating base 220 rotates to the opposite side of the fixed base 210, stress is not concentrated on one side of the elastic member 231, so the elastic member 231 is not deformed and its elastic restoring force This can be maintained for a long time.

In addition, the elastic member 231 of the present invention is not easily disengaged from the fixed base 210 even if the rotating base 220 rotates excessively.

In addition, the present invention can prevent the rotating base 220 from being excessively inserted into the concave groove 111 more effectively than the conventional invention.

The above description is merely an illustrative explanation of the technical idea of the present embodiment, and those skilled in the art will be able to make various modifications and variations without departing from the essential characteristics of the present embodiment.
