Description

  The present invention relates to a spring member and a lighting fixture, and is particularly suitable for use when a light emitting module is mounted on a fixture main body attached to a ceiling position.

  A light emitting diode (hereinafter referred to as an LED (Light Emitting Diode)) has attracted attention as a light emitting source used for illumination, and a light emitting module using various LEDs (hereinafter also referred to as an LED module) has been developed. For indoor lighting, line-type LED modules (hereinafter also referred to as line LED modules) have been developed instead of straight tube fluorescent lamps. As a lighting fixture using such a line LED module, for example, there is one described in Patent Document 1 below. The lighting fixture described in Patent Document 1 is used by mounting a line LED module on a fixture body attached to a ceiling position. Since the line LED module is elongated in one direction, the instrument body on which the line LED module is mounted is also elongated in one direction. In this illuminating device, a convex spring receiver is attached to the upper part of the line LED module, with a downward locking piece protruding. A spring member is attached to the instrument body attached to the ceiling position. Then, the line LED module is attached to the instrument body by pressing the spring receiver of the line LED module against the instrument body side disposed above by the restoring force of the spring member. The spring member includes a pair of two coil spring portions that are formed in a coil shape and spaced apart from each other in the coil axis direction, and an extension portion of the spring wire material that extends from one of these coil spring portions. Is bent so as to be locked to the locking piece of the spring receiver, and a frame portion continuous with the other of the coil spring portion is formed. The set of the spring member and the spring receiver is disposed at both ends in the longitudinal direction or near both ends in the longitudinal direction of the device main body and the line LED module. Then, in a state where the spring receiving locking piece is locked to the frame portion of the spring member, the line LED module is suspended from the fixture main body by the spring member, and when the line LED module is pushed up from there, it is formed in the frame portion of the spring member. The pressed portion presses the spring receiver upward with the restoring force of the coil spring portion, and the line LED module is mounted on the instrument body. When removing the line LED module, the line LED module is pulled down by hand, and the engagement between the spring member and the spring receiver is released in a state where the pressure of the spring receiver by the spring member is released.

Japanese Patent No. 5619228

However, in the lighting apparatus described in Patent Document 1, when the line-type LED module is to be removed, the spring receiver on the line LED module side is too close to the coil spring portion of the spring member of the apparatus body, and as a result. In some cases, it becomes difficult to release the pressure of the spring receiver by the spring member.
The present invention has been made paying attention to the above-described problems, and a spring that facilitates release of a spring receiver by a spring member when a light emitting module such as a line LED module is to be removed. It aims at provision of a member and a lighting fixture.

  In order to solve the above-described problem, according to one aspect of the present invention, in a lighting fixture to be mounted at a mounted position, a convex spring receiver having a locking piece projecting is mounted on an upper portion of a light emitting module.

The following embodiments exemplify apparatuses and methods for embodying the technical idea of the present invention, and the technical idea of the present invention is the material, shape, structure, arrangement, etc. of components. Is not specified as follows. The technical idea of the present invention can be variously modified within the technical scope defined by the claims described in the claims.
Next, an embodiment of a spring member and a lighting fixture of the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view of a fixture main body showing an embodiment of the spring member and the lighting fixture of this embodiment, and FIG. 2 is a perspective view of a line LED module mounted on the fixture main body of FIG. Although the lighting fixture of this embodiment is attached to the ceiling position which is a mounting position, especially the fixture main body 1 is embed | buried under a ceiling surface so that line LED module M itself may become substantially the same as a ceiling surface. The As is well known, a horizontal member such as a lip channel steel (C channel) is disposed inside the ceiling surface, and the instrument body 1 of this embodiment does not interfere with these horizontal members. Thus, the height is low.

  The fixture body 1 of the lighting fixture of this embodiment is used by attaching one line-type LED module M as a light emitter. Therefore, the instrument main body 1 is long in the longitudinal direction of the line LED module M. And the instrument main body 1 is a box with a substantially trapezoidal cross section that opens downward and has a substantially trapezoidal cross section. The lower opening square box constitutes the main body 1a of the instrument main body 1, and the line LED module M is formed in the lower opening. Used as a lighting fixture with the The main body 1a of the instrument main body 1 is formed by bending or joining metal plates by spot welding or the like. And the main-body part 1a of the instrument main body 1 is attached to the attachment site | part of a ceiling position with the anchor bolt (refer FIGS. 5-7) so that the upper surface may become horizontal or substantially horizontal. In addition, since the body part 1a of this embodiment is open at both ends in the longitudinal direction, a reinforcing member 1b made of a metal plate material is attached to the upper surface with screws 52.

  In the following description, it is assumed that the instrument main body 1 is arranged at the ceiling position so that the upper surface of the main body 1a is horizontal or almost horizontal, and the vertical direction in the sentence corresponds to the vertical direction of the figure, The longitudinal direction of 1 and the width direction of the instrument body 1 are used as a reference for two orthogonal directions in a horizontal plane. Further, the longitudinal direction of the instrument body 1 is simply referred to as the instrument body longitudinal direction, and the width direction of the instrument body 1 is simply referred to as the instrument body width direction. Further, since the line LED module M is described in detail in the above-described Patent Document 1, detailed description thereof is omitted.

  As shown in FIG. 3, a spring receiver 2 is attached to the upper surface (upper part) of the line LED module M. The spring receiver 2 is engaged with a spring member, which will be described later, and pressed against the instrument body 1 by the restoring force of the spring member. Yes. The spring receiver 2 is attached to the upper surface of the line LED module M at both ends in the longitudinal direction of the appliance main body or at positions near the both ends and in the central portion of the appliance main body in the width direction. The spring receiver 2 is formed by bending or joining metal plates by spot welding or the like. The spring receiver 2 has a main body portion 2a that is convex upward, and an opening is provided below the convex main body portion 2a. Both ends of the convex main body portion 2a are fixed to the upper surface of the line LED module M with screws 53. Has been. Of the spring receiver 2, a rectangular locking piece 3 is formed on the inner side in the longitudinal direction of the instrument body by bending the convex body portion 2a downward. Moreover, the guide groove 4 which dents the convex main-body part 2a toward the instrument main body longitudinal direction is formed in the instrument main body width direction both sides of the locking piece 3 among the convex main-body parts 2a of this spring receiver 2. As shown in FIG. Yes.

  On the other hand, the parts corresponding to the spring receiver 2 of the instrument main body 1, that is, the parts at both ends of the instrument main body in the longitudinal direction or near the both ends, and the upper surface (upper part) of the central part in the instrument main body width direction are shown in FIGS. As shown, the spring member 6 is attached via the spring fixing member 5. Each of the spring members 6 is formed by bending one spring wire. In this spring member 6, a spring wire member extending from one of two pairs of coil spring portions 7 and coil spring portions 7 formed in a coil shape and spaced apart in the coil axial direction is a spring. A frame portion 8 formed to be bent so as to be locked to the locking piece 3 of the receiver 2 is formed on the other side of the coil spring portion 7. Further, the frame portion 8 is formed by bending the spring wire of the frame portion 8 near the coil spring portion 7 of the frame portion 8 and restricts the movement of the spring receiver 2 in the direction of the coil spring portion 7. The pressing portion 10 is formed by bending the spring wire of the frame portion 8 in a direction away from the device main body 1 from a portion opposite to the coil spring portion 7 with the spring receiving restriction portion 9 interposed therebetween, and presses the spring receiver 2 toward the device main body 1 side. The finger hook part 11 formed by bending the spring wire material of the frame part 8 in a direction adjacent to the instrument body 1 continuously to the pressing part 10, and the latching piece 3 of the spring receiver 2 continuously locked to the finger hook part 11 A locking portion 12 formed by bending the spring wire of the frame portion 8 into a shape to be formed is formed. Further, an abutting portion 13 for applying a restoring force to the frame main body 1 side to the frame portion 8, particularly the pressing portion 10, is formed at a portion opposite to the frame portion 8 with the coil spring portion 7 interposed therebetween. In addition, in this embodiment, since the main-body part 1a of the instrument main body 1 was made thin in the height direction as mentioned above, the length of the finger hook part 11 is made shorter than what is described in the above-mentioned patent document 1. . Moreover, when making the main-body part 1a of the instrument main body 1 still thinner in the height direction, it is necessary to make the finger hook part 11 still shorter. Then, by shortening the finger-hanging portion 11, it may be easy to attach / remove the line LED module M described later.

  The spring fixing member 5 is fixed to the upper surface portion of the main body portion 1 a of the instrument main body 1 with screws 54 while supporting the coil spring portion 7 of the spring member 6. When the spring fixing member 5 is fixed to the main body portion 1a of the instrument main body 1 while the coil spring portion 7 of the spring member 6 is supported in this manner, the abutting portion 13 of the spring member 6 becomes the upper surface portion of the main body portion 1a of the instrument main body 1. (Refer to FIG. 9) and elastically deformed, and the coil spring portion 7 urges the pressing portion 10 with a restoring force toward the instrument body 1 along with the elastic deformation. Therefore, for example, as shown in FIGS. 8 and 9, the spring receiver 2 is moved toward the instrument body 1 by the restoring force of the spring member 6 in a state where the upper surface of the convex portion of the spring receiver 2 is in contact with the pressing portion 10 of the spring member 6. As a result, the line LED module M is mounted on the instrument body 1. Further, as described in Patent Document 1 described above, the bent portion formed between the pressing portion 10 and the finger hooking portion 11 of the frame portion 8 is used by the operator when the frame portion 8 is pulled down. Thus, the locking piece 3 of the spring receiver 2 attached to the line LED module M can be easily locked to the locking portion 12 of the frame portion 8. . A concave portion is formed on the upper surface portion of the main body portion 1 a of the instrument main body 1 in order to avoid interference with the spring receiving restriction portion 9 of the spring member 6.

  When the line LED module M is mounted on the instrument main body 1, the finger is hooked on the finger hook portion 11 of the spring member 6 attached to the instrument main body 1 from the state shown in FIG. Pull down part 8 downward. In this state, the locking piece 3 of the spring receiver 2 attached to the line LED module M is locked to the locking portion 12 of the frame portion 8 of the spring member 6. When the spring members 6 at both ends in the longitudinal direction of the instrument body or near the both ends are locked to the spring receiver 2, the line LED module M is suspended from the instrument body 1 by the two spring members 6. Then, when the line LED module M is pushed up from this state, as shown in FIGS. 8 and 9, the frame portion 8 of the spring member 6 slides on the guide groove 4 of the spring receiver 2 in the order of the finger hook portion 11 and the pressing portion 10. The pressing portion 10 presses the spring receiver 2 upward by the restoring force of the coil spring portion 7, and the line LED module M is mounted on the instrument body 1.

  On the other hand, when removing the line LED module M, the line LED module M is pulled down by hand, and the pressure of the spring receiver 2 by the spring member 6 is released. In the spring member and the lighting fixture of this embodiment, a spring receiving restricting portion 9 is formed in a portion near the coil spring portion 7 in the frame portion 8 of the spring member 6, and the coil receiving portion 9 of the spring receiver 2 is formed by the spring receiving restricting portion 9. Since the movement in the seven directions is restricted, it is possible to easily release the spring receiver 2 by the spring member 6. When removing the line LED module M from the state shown in FIG. 10, it is only necessary to pull down both ends in the longitudinal direction of the line LED module M while keeping it horizontal, but only one of the longitudinal directions as shown in FIG. May be pulled down first. In this way, when only one of the longitudinal directions of the line LED module M is pulled downward first, an obliquely downward force is applied to the line LED module M due to gravity. Due to the oblique downward force acting on the line LED module M, the spring receiver 2 attached to the line LED module M moves toward the coil spring portion 7 of the spring member 6.

  If the spring receiving restriction portion 9 is not formed on the spring member 6 as in the prior art, the spring receiver 2 moves to the vicinity of the coil spring portion 7 of the spring member 6 as shown in FIG. The removal of the line LED module M is performed by pulling the line LED module M downward against the restoring force of the spring member 6 acting on the spring receiver 2 to the instrument body 1 side. 6 close to the coil spring portion 7 side, the moment arm for resisting the restoring force of the coil spring portion 7 is shortened, and the spring member 6 acting on the spring receiver 2 to the instrument main body 1 side unless applied with a very large force. The line LED module M cannot be pulled down against the restoring force. In this case, in some cases, it may be necessary to repeat the operation of restoring the line LED module M to the state in which the line LED module M is mounted on the instrument main body 1 and then pulling down the line LED module M again. On the other hand, in the spring member and the lighting fixture of this embodiment, since the movement of the spring receiver 2 in the direction of the coil spring portion 7 is restricted by the spring receiver restricting portion 9, it is easy to release the pressure of the spring receiver 2 by the spring member 6. This makes it easy to remove the line LED module M.

  Thus, in the spring member and the lighting fixture of this embodiment, in the lighting fixture that is attached to the ceiling position, which is the attached position, the locking piece 3 protrudes above the line LED module M. A convex spring receiver 2 is attached to the top. Further, a spring member 6 for attaching the line LED module M to the instrument body 1 by pressing the spring receiver 2 toward the instrument body 1 with a restoring force is attached to the instrument body 1 side. The spring member 6 is formed in a coil shape, and a pair of two coil spring portions 7 that are spaced apart from each other in the coil axis direction, and an extension of the spring wire material that extends from one of the coil spring portions 7. The frame portion 8 is formed so as to be bent so as to be locked to the locking piece 3, and is connected to the other side of the coil spring portion 7, and the spring wire of the frame portion 8 is located near the coil spring portion 7 of the frame portion 8. A spring receiving restriction portion 9 that is formed by bending and restricts the movement of the spring receiver 2 in the direction of the coil spring portion 7 is provided. Therefore, when removing the line LED module M from the instrument body 1, it is possible to restrict the spring receiver 2 from being too close to the coil spring portion 7 side of the spring member 6. This can be easily performed, and the removal operation of the line LED module M is facilitated.

  The frame portion 8 is formed by bending the spring wire of the frame portion 8 in a direction away from the device main body 1 from a portion opposite to the coil spring portion 7 with the spring support restricting portion 9 interposed therebetween, and the spring support 2 is attached to the device main body 1 side. A pressing portion 10 that presses against the instrument body 1, a finger hook portion 11 formed by bending the spring wire of the frame portion 8 in a direction adjacent to the instrument body 1, and a spring receiver that is continuous with the finger hook portion 11. And a locking portion 12 formed by bending the spring wire of the frame portion 8 into a shape to be locked by the two locking pieces 3. Therefore, when the spring receiver 2 can be effectively pressed to the instrument body 1 side by the pressing part 10 of the frame part 8 of the spring member 6, and the locking part 12 of the frame part 8 is separated from the instrument body 1 side. Can be easily performed by placing a finger on the finger-hanging portion 11, and the locking portion 12 can be securely locked to the locking piece 3 of the spring receiver 2 to support the line LED module M. .

In addition, the spring receiving restriction portion 9 is configured to protrude upward from the frame portion 8 in a state in which the instrument body 1 is attached to the attachment position. Thereby, the movement to the coil spring part 7 direction of the spring receiver 2 can be controlled effectively.
In the above-described embodiment, only the lighting fixture attached to the ceiling position has been described. However, the lighting fixture of the present invention and the spring member used therefor can also be applied to those attached to a mounting position other than the ceiling. .

Moreover, you may provide a spring member in a line LED module and a spring receiver in an instrument main body.
Moreover, although the LED module was used for the light emitting module, it can replace with this and can also use light emitting modules, such as a fluorescent lamp.
It goes without saying that the present invention includes various embodiments not described herein. Therefore, the technical scope of the present invention is defined only by the invention-specific matters described in the appropriate claims from the above description.
