  However, in the lighting fixture disclosed in Patent Document 1, the V spring and the guide fitting are engaged with each other while the elastically deformed state is maintained so that the V spring is closed inward. As described above, in Patent Document 1, when the globe and the lighting fixture are attached and detached, it is necessary to continuously apply an external force to the V spring by hand or the like, and workability is poor.

  The present invention has been made against the background of the above problems, and provides a lighting apparatus with improved workability.

  A lighting fixture according to the present invention includes a frame body to which an elastic member is attached, and an appliance main body to which a receiving member having an opening into which the elastic member is inserted is attached. The elastic member includes a base portion and a base portion. A pair of arm portions extending from both ends and a coupling portion that maintains an elastically deformed state in which the pair of arm portions are brought close to each other and biased away from each other with the base as a starting point. The elastic deformation state is released as the arm portion slides on the edge portion of the opening portion.

  According to the present invention, the coupling portion maintains an elastically deformed state, and the elastic member is inserted into the opening portion of the receiving member in the elastically deformed state, and the elastic portion is elastic as the arm portion slides on the edge portion of the opening portion. Since the deformed state is released, workability is improved.

Further, the upper convex portion 51a and the lower convex portion 51c of the fastener 51 are provided with convex portions (not shown) formed by embossing or the like on the surface. And when this convex part contacts the elastic member 1, the movement (shift | offset | difference) to the horizontal direction (arrow Y direction) etc. of the elastic member 1 is blocked | prevented. Thereby, the elastic member 1 can be elastically deformed smoothly.

  As shown in FIG. 3, the frame 5 has a V-shaped cross-section that covers the power terminal block 42 and the like in the instrument main body 4 when the frame 5 is fixed to the instrument main body 4 and the longitudinal direction (the direction of the arrow X). The cover 53 extending to () is fixed using a screw or the like. Since the frame 5 is opened except for the portion where the cover 53 is provided, when the frame 5 is fixed to the instrument body 4, two lights on the instrument body 4 are turned on as shown in FIG. The unit 41 is exposed from the frame body 5. The lighting unit 41 may be provided on the frame 5.

  FIG. 5 is a front view showing the elastic member 1 according to the first embodiment. The elastic member 1 fixed to the frame 5 is a torsion spring produced by bending a member having an elastic force such as a steel plate. As shown in FIG. 5, the elastic member 1 includes a base portion 11, a pair of arm portions 12, and a coupling portion 13. The base 11 has, for example, a coil shape wound in an annular shape, and is fixed to the fastener 51.

  The pair of arm portions 12 extends from both ends of the base portion 11 and has, for example, a V shape or a U shape in a front view. And the arm part 12 is urged | biased in the direction which leaves | separates from the base part 11, ie, the width direction (arrow (alpha) direction) of the elastic member 1. FIG. In FIG. 5, the arm portion 12 includes a first straight portion 21 extending from both ends of the base portion 11, a first bent portion 22 at the tip of the first straight portion 21, and a second bent portion extending from the first bent portion 22. And a second bent portion 24 at the tip of the second straight portion 23. Thus, the arm part 12 is curved so as to be convex outward. In addition, the number of these linear parts and bending parts can be changed suitably. Moreover, you may provide not only a linear part and a bending part but a curved part.

  The connecting portion 13 maintains an elastically deformed state in which the pair of arm portions 12 are brought close to each other in the arrow β direction and biased in a direction away from the base portion 11 (arrow α direction). In the first embodiment, the coupling portion 13 is an engaging portion 14 provided at the tip of the arm portion 12. The engaging portion 14 includes a proximal end portion 31 provided at the distal end of the arm portion 12 and extending so as to face each other, and a distal end portion 32 provided at the distal end of the proximal end portion 31 and extending away from each other. .

  FIG. 6 is a front view showing an elastically deformed state of the elastic member 1 according to the first embodiment. As shown in FIG. 6, the engaging portion 14 is provided at the tip of the arm portion 12 and maintains an elastically deformed state biased in directions away from each other (arrow α direction) starting from the base portion 11. In addition, since the base end part 31 in the engaging part 14 is extended so as to face each other, the engaging parts 14 are easily engaged with each other.

  FIG. 7 is a plan view showing the elastic member 1 according to the first embodiment. As shown in FIG. 7, one arm portion 12 includes a stepped portion 12 a in which a step is formed in a direction away from each other (depth direction) (arrow Y direction). By forming a step in the direction away from each other in the stepped portion 12a (arrow Y direction), when the pair of engaging portions 14 are engaged in an elastically deformed state, the arms 12 are separated from each other by the amount of the step. The engaging portions 14 are brought closer to each other while being urged in the direction of arrow Y. For this reason, in the elastically deformed state, the urging force acts on the arm 12 not only in the width direction (arrow α direction) but also in the depth direction (arrow Y direction). Therefore, in the elastically deformed state, when the engagement of the pair of engaging portions 14 is released, the tip of the engaging portion 14 is easily spread by the biasing force (restoring force) in the depth direction (arrow Y direction).

  FIG. 8 is a perspective view showing the receiving member 6 in the first embodiment. The receiving member 6 fixed to the instrument body 4 has an L-shaped cross section and extends in the longitudinal direction (arrow X direction), and a fixing part 61 that contacts the instrument body 4 and is fixed using a screw or the like. , And an engaging portion 62 having an opening 63 connected to the fixing portion 61. The opening 63 provided in the locking part 62 has an elliptical shape, and the elastic member 1 is inserted in a direction perpendicular to the locking part 62 (downward direction) (arrow Z direction). In FIG. 8, the opening 63 has a predetermined width Wo.

  FIG. 9 is a front view showing dimensions of the elastic member 1 according to Embodiment 1 in an elastically deformed state. As shown in FIG. 9, the width of the pair of engaging portions 14 engaged in the elastically deformed state is We, and the maximum width of the pair of arm portions 12 in the elastically deformed state is Wa. In this case, the width Wo of the opening 63 in the receiving member 6 is larger than the width We of the pair of engaged portions 14 engaged in the elastically deformed state, and larger than the maximum width Wa of the pair of arm portions 12 in the elastically deformed state. Is also formed small. That is, the relationship of We ≦ Wo ≦ Wa holds.

  Since the width Wo of the opening 63 in the receiving member 6 is larger than the width We of the pair of engaged portions 14 engaged in the elastic deformation state, the elastic member 1 in the elastic deformation state is inserted into the opening 63. be able to. Further, since the width Wo of the opening 63 in the receiving member 6 is smaller than the maximum width Wa of the pair of arms 12 in the elastically deformed state, when the elastic member 1 is inserted into the opening 63, the elastic member 1 In the region of the arm 12 that is larger than the width Wo of the opening 63, the arm 12 slides on the edge 63 a of the opening 63. Thus, the elastic member 1 is inserted into the opening 63 of the receiving member 6 in the elastically deformed state, and the elastically deformed state is released as the arm 12 slides on the edge 63a of the opening 63. It is going.

  In the first embodiment, the width We of the pair of engaged portions 14 engaged in the elastically deformed state is larger than the maximum width Wa of the pair of arm portions 12 in the elastically deformed state. The width Wo is equal to or less than the value obtained by subtracting the width Wo, that is, We ≦ Wa−Wo. Thus, the elastic deformation state is accurately canceled. As the arm portion 12 slides along the edge 63a of the opening 63, the engagement of the pair of engaging portions 14 is about to be released. However, when the width We of the pair of engaging portions 14 is equal to or greater than the value obtained by subtracting the width Wo of the opening 63 from the maximum width Wa of the pair of arms 12, the arm 12 is connected to the edge 63 a of the opening 63. Even if it is slid and the engagement of the pair of engaging portions 14 is once released, it may be engaged again before the release of the engagement is completed. In the first embodiment, the elastic deformation state is reliably released by setting We ≦ Wa−Wo.

  Next, the effect | action of the lighting fixture 3 which concerns on this Embodiment 1 is demonstrated. First, the operation of attaching the frame 5 to the instrument body 4 will be described. FIGS. 10-14 is a front view which shows transition of the elastic deformation state of the elastic member 1 which concerns on Embodiment 1. FIG. As shown in FIG. 10, first, in the elastic member 1, the pair of engaging portions 14 is a direction in which the pair of arm portions 12 are brought close to each other in the arrow β direction and separated from each other starting from the base 11 (arrow α direction). Is engaged in an elastically deformed state urged by. Then, the side of the engaging portion 14 of the elastic member 1 in the elastically deformed state (in the direction of the arrow Z1) is directed to the opening 63 of the receiving member 6.

  Thereafter, as shown in FIG. 11, the engaging portion 14 of the elastic member 1 is inserted into the opening 63 of the receiving member 6. Then, as the arm portion 12 of the elastic member 1 slides along the edge portion 63a of the opening 63, the pair of arm portions 12 are closer to each other than the elastically deformed state. Thereby, the engagement between the pair of engaging portions 14 is released. That is, the elastic member 1 is inserted into the opening 63 of the receiving member 6 in an elastically deformed state, and the elastically deformed state is released as the arm 12 slides on the edge 63a of the opening 63. It is.

  When the elastic member 1 is further inserted into the opening 63 of the receiving member 6, as shown in FIG. 12, the pair of arm portions 12 come closest to each other, and thereby a repulsive force against the urging force of the arm portion 12 ( (Restoring power) is maximized. When the elastic member 1 is further inserted into the opening 63 of the receiving member 6 from this state, the repulsive force is gradually weakened. Thereafter, as shown in FIG. 13, the base 11 of the elastic member 1 reaches the opening 63 of the receiving member 6.

  As shown in FIG. 14, when the entire base 11 of the elastic member 1 is accommodated in the opening 63 of the receiving member 6, there is no external force applied to the elastic member 1, and the arm 12 is urged and fully extended. It becomes a state. Thereby, it becomes the lighting fixture 3 by which the frame 5 to which the elastic member 1 was attached was fixed to the fixture main body 4 to which the receiving member 6 was attached.

And if the frame 5 is further pulled down so that it may leave | separate from the instrument main body 4, it will transfer to the state of FIG. 12 from the state of FIG. 13, and will transfer to the state of FIG.

  When the frame 5 is pulled down from the state of FIG. 11 so as to be separated from the instrument body 4, the elastic member 1 is not in an elastically deformed state as shown in FIG. The hook is caught on the outer periphery of the opening 63 of the receiving member 6. Thereby, the frame 5 is prevented from falling from the instrument body 4. From this state, when the elastic member 1 is pulled out from the receiving member 6 by applying an external force to the elastic member 1 by hand or the like, the frame body 5 is removed from the instrument body 4.

  As described above, in the lighting fixture 3 according to the first embodiment, since the coupling portion 13 in the elastic member 1, for example, the engagement portion 14 maintains an elastically deformed state, the elastic member 1 itself is in an elastically deformed state. Can be maintained. The elastic member 1 is inserted into the opening 63 of the receiving member 6 in the elastically deformed state, and the elastically deformed state is released as the arm portion 12 slides on the edge 63a of the opening 63. Thus, the elastic member 1 maintains its elastically deformed state by itself and is inserted into the receiving member 6 to release the elastically deformed state. That is, when the frame 5 is attached to the instrument body 4, it is not necessary to apply an external force to the elastic member 1 by hand or the like. Therefore, the mounting workability of the lighting fixture 3 is improved.

  Further, when the frame body 5 is removed from the instrument body 4, when the frame body 5 is pulled away from the instrument body 4, even if the frame body 5 is accidentally dropped, the engaging portion 14 opens the receiving member 6. It catches on the outer periphery of the part 63. Thereby, it can prevent that the frame 5 falls from the instrument main body 4. FIG. Therefore, the workability for removing the lighting fixture 3 is also improved.
