JP 2010-137719 A

  However, according to Patent Document 1, there is a problem that the workability of lamp replacement is poor because the functional part is engaged with the design part again after the functional part is removed from the design part and the lamp is replaced.

  The problem to be solved by the present invention is to improve the workability of lamp replacement.

  In order to solve the above-described problems, the present invention provides a design portion including a bezel to which a window that transmits light of a lamp is attached, and a functional portion that detachably supports the lamp and is engaged with the design portion. The function unit is engaged with the design unit so that the lamp can be moved between the irradiation position and the replacement position. It is characterized by becoming.

  According to this, since the lamp can be moved from the irradiation position to the replacement position when the lamp is replaced, the lamp can be replaced with the functional portion engaged with the design portion, so that the workability of the lamp replacement can be improved. That is, if there is a member that hinders attachment / detachment of the lamp at the irradiation position, the lamp cannot be replaced unless the functional part is removed from the design part. In this regard, according to the present invention, if the position where there is no member that hinders the attachment / detachment of the lamp is set as the replacement position, the lamp can be replaced without removing the functional section from the design section.

  For example, when the lamp is replaced by removing the design window and inserting a finger from the bezel opening, if the lamp mounting / removal direction is parallel to the window surface, the fingertip will hit the bezel and the lamp mounting / removal will be hindered. There is. In this case, the function part is engaged with the design part so that the lamp rotates in a plane orthogonal to the surface of the window, and the position where the attaching / detaching direction of the lamp faces the opening of the bezel is set as the replacement position. The lamp can be replaced while the part is engaged with the design part.

  In this case, the functional unit can be rotated in a plane orthogonal to the plane of the window and moved to the lamp replacement position. For example, a pair of support pieces erected facing each other at an interval is formed in the design portion, holes or recesses are formed in the opposing surfaces of the pair of support pieces, and the pivots can be pivoted in the holes or recesses. A structure can be adopted in which the boss to be stopped is formed in the functional portion, the functional portion is axially fixed between the pair of support pieces, and the functional portion is engaged with the design portion. According to this, since the lamp can be protruded from the opening of the bezel by removing the window from the bezel and rotating the functional portion into the opening of the bezel, the lamp can be easily replaced. On the contrary, a structure in which a boss is formed on the opposing surfaces of the pair of support pieces and a hole or a recess is formed in the functional part can be adopted.

  On the other hand, when the bezel is engaged and fixed to the opening edge of the member at the mounting position, a protruding portion that can be elastically deformed is provided on the bezel, and the protruding portion is inserted into the opening while being deformed and locked to the opening edge. It is possible to make it. In this case, the projection may prevent the lamp from being attached or detached. Therefore, the functional part is engaged with the design part so that the lamp rotates in a plane parallel to the window surface, and the design part is associated with the functional part by setting the replacement position at a position where there is no protrusion. The lamp can be replaced with the lamp in place.

  In this case, the functional unit can be rotated in a plane parallel to the window surface and moved to the lamp replacement position. For example, a hole or recess is formed in the surface of the design part parallel to the window, a boss pivotally supported in the hole or recess is formed in the function part, and the boss of the function part is formed in the hole or recess of the design part. It is possible to employ a structure in which the functional portion is engaged with the design portion by stopping the shaft. According to this, since the lamp can be moved to the replacement position where there is no protrusion, the lamp can be easily replaced. Conversely, a structure in which a boss is formed in the design portion and a hole or a recess is formed in the functional portion can be adopted.

  In addition, the movement of the lamp between the irradiation position and the replacement position is not limited to rotation, for example, a structure in which the functional unit is slid with respect to the design portion and the lamp is moved to the replacement position that does not hinder lamp replacement, etc. Can be appropriately selected.

  Moreover, the latching | locking part which fixes the movement of a function part to an irradiation position and an exchange position can be provided. According to this, when replacing the lamp, the lamp can be fixed at the replacement position, so that the lamp can be easily replaced. On the other hand, when irradiating light from the lamp, the lamp can be fixed at the irradiation position, so that light can be stably irradiated toward the irradiation target.

  According to the present invention, the workability of lamp replacement can be improved.

Hereinafter, the present invention will be described based on embodiments.
(Embodiment 1)
As shown in FIGS. 1-5, the illuminating device 1 of Embodiment 1 is illuminating devices, such as a vanity lamp attached to the ceiling of a vehicle, for example, and the lens 4 which is a window which permeate | transmits the light of the lamp | ramp 3 is attached. A design portion 7 having a bezel 5 and a functional portion 9 that detachably supports the lamp 3 and is engaged with the design portion 7 are provided. The illuminating device 1 is attached to the vehicle ceiling by attaching the bezel 5 to an opening 13 formed in a member at an attachment position, for example, an interior material 11 of the vehicle ceiling.

  The design portion 7 includes, for example, a bezel 5 that is formed of a resin into a substantially rectangular frame shape. A substantially rectangular opening 19 to which the lens 4 is attached is formed in the bezel 5. A groove into which the pair of projections 15 of the lens 4 is inserted is formed on the inner peripheral surface of the opening 19. The lens 4 is detachably attached to the indoor side surface of the bezel 5 from the direction of arrow 17 in FIG. On opposite sides of the bezel 5, a snap fit 21 and a pair of protrusions 23 that are protrusions that engage with an engagement part 30 described later of the interior material 11 are formed. The snap fit 21 is erected in a mountain shape so as to protrude from the back side of the interior material 11. The snap fit 21 is formed with a skirt 22 that protrudes outward of the frame of the bezel 5, and the skirt 22 is engaged with the engagement portion 30 of the interior material 11. A concave portion is provided at the tip of the pair of projecting portions 23, and the engaging portion 30 of the interior material is inserted into the concave portion and locked therein.

  The function unit 9 includes a socket 25 that is a support unit that detachably supports the lamp 3, and a binding unit 29 that bundles a plurality of electric wires 27 connected to the socket 25. The socket 25 is provided with an opening 31 into which the lamp 3 is inserted. The lamp 3 is inserted from the direction of the arrow 32 in FIG. 2 toward the opening 31 and is supported by the socket 25. An electric wire 27 is connected to the socket 25 so that power can be supplied to the lamp 3. The lamp 3 may be a known light source such as a light bulb or an LED with a circuit.

  In the interior material 11 to which the lighting device 1 is attached, an opening 13 formed in a substantially rectangular shape corresponding to the bezel 5 is formed. An engaging portion 30 formed smaller than the frame size of the bezel 5 is provided at the edge of the opening 13. The engaging portion 30 is formed with a convex portion 34 that is convex toward the back side of the interior material 11 and an insertion portion 36 that is formed thinner than other portions. The convex portion 34 is adapted to come into contact with the skirt portion 22 of the snap fit 21 of the bezel 5. The insertion portion 36 can be inserted into the recesses of the pair of projecting portions 23 of the bezel 5. Thereby, the bezel 5 is locked and engaged with the opening 13 of the interior material 11.

  Next, the characteristic configuration of the first embodiment will be described with reference to FIGS. A pair of support pieces 33 are formed on the back surface side of the bezel 5 so as to face each other with a gap therebetween. Each support piece 33 is formed with a circular hole 39 penetrating the opposing surface of the support piece 33 and a notch 40 formed from the edge of the support piece 33 toward the hole 39. The width dimension of the notch part 40 is a dimension which can insert the boss | hub 47 mentioned later. On the back surface (the position of the circle 6b) of the bezel 5 located between the support pieces 33, a protrusion 45 that engages with a locking portion 50 of the functional portion 9 described later is formed. The protrusion 45 is formed in a triangular cross section with, for example, an elastic resin.

  On the other hand, a pair of columnar bosses 47 are formed in the functional unit 9. Each boss 47 is formed on the side surface of the functional part 9 corresponding to the hole 39 of the design part 7. Each boss 47 is inserted into the cut portion 40 of the support piece 33 of the design portion 7 and is rotatably fixed to the hole 39. Thereby, the function part 9 can be engaged with the design part 7 so that rotation is possible. On the lower surface of the functional part 9, a locking part 50 that engages with the protrusion 45 of the design part 7 and restricts the rotation of the functional part 9 is formed. The locking part 50 is formed at a position facing the protrusion 45 of the design part 7 (position of the circle 7b). The locking portion 50 is formed on the lower surface of the functional portion 9 that intersects with a plane passing through the pair of bosses 47. The engaging portion 50 is provided with a plurality of teeth 51 formed in a curved surface that protrudes downward. The plurality of teeth 51 are arranged along the attaching / detaching direction of the lamp 3. The groove dimension between the teeth 51 is formed such that the protrusion 45 of the design portion 7 is inserted and engaged.

  The operation of attaching the lighting device 1 of the first embodiment configured as described above to the interior material 11 of the vehicle ceiling will be described with reference to FIGS. First, an operation of engaging the design portion 7 to which the lens 4 is attached and the functional portion 9 to which the lamp 3 is supported will be described with reference to FIG. The functional portion 9 is inserted between the support pieces 33 of the design portion 7 along the direction parallel to the lens 4 (arrow 53) from the lamp 3 side. At this time, the boss 47 of the functional unit 9 is inserted from the notch 40 toward the hole 39 formed on each support piece 33 of the design unit 7. If the width dimension of the notch 40 is set smaller than the diameter of the boss 47, when the boss 47 passes through the notch 40, the notch 40 is elastically deformed in the direction in which the width increases. Then, after the boss 47 passes through the notch 40, the notch 40 returns to the original width and the escape of the boss 47 is restricted. Thereby, the boss 47 is rotatably supported in the hole 39, and the functional portion 9 is rotatably engaged with the design portion 7 so that the lamp 3 moves in a plane orthogonal to the surface of the lens 4. Further, since the projection 45 of the design part 7 is engaged with the groove between the teeth 51 of the function part 9 at the position where the function part 9 is engaged with the design part 7, the function part 9 is restricted from rotating. The position of the part 9 is fixed.

  Next, the operation of attaching the lighting device 1 to the interior material 11 of the vehicle ceiling will be described with reference to FIG. 9 is a cross-sectional view taken along the dashed line AA in FIG. The functional portion 9 faces the opening 13 of the interior material 11, and the insertion portion 36 provided in the engagement portion 30 of the interior material 11 is inserted into the recess of the projecting portion 23 of the bezel 5 and engaged. The bezel 5 is pushed up toward the ceiling of the vehicle (arrow 63) with the engaging position of the protruding portion 23 and the insertion portion 36 as an axis. At this time, the snap fit 21 comes into contact with the engaging portion 30 of the opening 13 and is elastically deformed to the functional portion 9 side (arrow 65 side). When the skirt portion 22 of the snap fit 21 passes through the engaging portion 30, the snap fit 21 returns to the original state, and the skirt portion 22 contacts the convex portion 34 of the engaging portion 30. The convex portion 34 is locked by being sandwiched between the bezel 5 and the skirt portion 22, and the bezel 5 is attached to the opening 13. As a result, the lamp 3 is positioned in the space behind the interior material 11, and the lighting device 1 is attached to the interior material 11 on the vehicle ceiling. In addition, as shown to FIG.9 (b), the illuminating device 1 sets the position where the attachment or detachment direction of the lamp | ramp 3 becomes parallel to the lens 4 to an irradiation position.

  Next, replacement work of the lamp 3 will be described with reference to FIGS. 11 is a cross-sectional view taken along the dashed line BB in FIG. 10, and FIGS. 12 and 13 are cross-sectional views taken along the dashed line CC in FIG. First, in the state of the irradiation position of the lamp 3 in FIG. 11A, for example, the jig 67 is pushed between the lens 4 and the bezel 5, and the jig 67 is moved in a direction (arrow 69) in which the projection 15 of the lens 4 is detached from the bezel 5. By operating, the lens 4 is removed from the bezel 5 as shown in FIG. Thereby, the opening 19 of the bezel 5 is exposed, and the lamp 3 can be touched from the opening 19.

  Next, for example, a finger is put in the gap 71 between the bezel 5 of the opening 19 and the tip of the lamp 3, and the lamp 3 is picked by the finger. In this state, the function unit 9 is rotated in a direction orthogonal to the surface of the opening 19 (arrow 73), and the lamp 3 is placed at the lamp replacement position in which the attaching / detaching direction of the lamp 3 shown in FIG. Move. Thereby, the lamp 3 projects toward the opening 19. At this time, while the projection 45 of the design portion 7 is elastically deformed, the locking portion 50 of the functional portion 9 rotates like a gear, and corresponds to the lamp replacement position in the groove between the teeth 51 of the locking portion 50. The protrusion 45 is engaged with the groove to be engaged. Thereby, the function part 9 can be fixed to a lamp replacement position. For example, the groove on the left by two with respect to the engagement position of the protrusion 45 at the lamp irradiation position in FIG. 12A is the engagement position corresponding to the lamp replacement position in FIG. In this state, the lamp 3 is extracted from the opening 19 of the bezel 5, and a new lamp 3 is inserted into the socket 25 to support the lamp 3 on the functional unit 9. Thereafter, the functional unit 9 at the lamp replacement position shown in FIG. 13A is pushed in the direction of the space behind the interior material 11 (arrow 75), and the functional unit 9 is returned to the lamp irradiation position shown in FIG. Then, the lens 4 is attached to the bezel 5 and the replacement work of the lamp 3 is completed.

  According to this, when the lamp 3 is replaced, the functional part 9 is engaged with the design part 7 because the mounting direction of the lamp 3 can be directed to the opening 19 while avoiding the bezel 5 that prevents the mounting of the lamp 3. The lamp 3 can be replaced as it is, and the workability of the lamp replacement can be improved. Furthermore, since the lamp 3 can be replaced while the lighting device 1 is attached to the interior material 11, it is not necessary to remove the lighting device 1 from the interior material 11 using a jig, and the interior material 11 is prevented from being damaged by the jig. it can.

  In addition, when the lamp 3 is replaced by replacing the projection 3 of the design part 7 with the engaging part 50 of the function part 9 and fixing the function part 9 to the irradiation position and the replacement position of the lamp 3, Since the lamp 3 can be fixed at the position, the lamp can be easily replaced. On the other hand, when irradiating light from the lamp 3, since the lamp 3 can be fixed at the irradiation position, the irradiation direction of the lamp 3 can be fixed, and light can be stably irradiated toward the interior of the vehicle.

  In addition, by arranging a large number (five in the figure) of teeth 51 in the locking portion 50 and forming a large number of grooves that engage with the protrusions 45, the functional portion 9 can be fixed at a position other than the irradiation position and the replacement position. The irradiation range of the lamp 3 can be adjusted. For example, as shown in FIG. 14A, when the lamp 3 is moved away from the lens 4, the irradiation range 81 in which the lamp 3 illuminates the interior of the vehicle becomes narrow. On the other hand, as shown in FIGS. 14B and 14C, as the lamp 3 is brought closer to the lens 4, the irradiation range 81 in which the lamp 3 illuminates the interior of the vehicle becomes wider. Therefore, by changing the position of the groove of the locking portion 50 with which the protrusion 45 is engaged, the irradiation position of the lamp 3 is changed and the irradiation range can be adjusted.

  Moreover, the latching | locking part which fixes the function part 9 is not limited to Embodiment 1, For example, the gear centering on the boss | hub 47 is attached to the function part 9, and the protrusion 45 of the design part 7 is meshed | engaged with this gear. A configuration for fixing the functional unit 9 can be employed.

  In the first embodiment, the boss 47 of the functional unit 9 is rotatably supported in the hole 39 of the design unit 7. On the contrary, the boss formed on the design unit 7 in the hole formed in the functional unit 9. Can be configured to be pivotally supported. Moreover, it can replace with the hole 39 and it can comprise so that a recessed part may be formed and a boss | hub may be axially fixed to a recessed part.

  In the first embodiment, the function unit 9 is rotated to move the lamp 3 to the replacement position. However, the present invention is not limited to this. For example, a rail is formed in the function unit 9 and a groove that engages with the rail is formed. The structure etc. which form in the design part 7 and slide the function part 9 with respect to the design part 7 and move the lamp | ramp 3 to an exchange position etc. are employable. That is, the gist of the present invention is to move the position of the lamp 3 to an exchange position where there is no member that prevents the attachment / detachment of the lamp 3, and the means for moving the lamp 3 can be selected as appropriate.

  Moreover, the attachment position of the illuminating device 1 is not limited to the interior material of a vehicle ceiling, For example, the interior material of a door, the interior material of a luggage compartment, etc. can be selected suitably.

  Moreover, the attachment object of the illuminating device 1 is not limited to a vehicle, For example, it can attach to buildings, such as a house.

(Embodiment 2)
The illuminating device of Embodiment 2 is demonstrated using FIG. The second embodiment differs from the first embodiment in that the moving direction of the lamp 3 is set in a plane parallel to the lens 4. Since other configurations are the same as those of the first embodiment, the same reference numerals are given and description thereof is omitted.

  Although not shown in the drawing, a substantially cylindrical boss projecting toward the functional unit 9 is erected on the back side of the design portion 7. On the other hand, a circular hole (not shown) is formed on the lower surface of the functional portion 9 facing the design portion 7 so as to rotatably support the boss of the design portion. Thereby, the function part 9 can be engaged with the design part 7 so as to be rotatable in the direction of the arrow 85.

  According to this, since the lamp 3 at the irradiation position in FIG. 15 can be moved in a plane parallel to the lens 4, the lamp 3 can be moved to the replacement position of the lamp 3 where the attaching / detaching direction of the lamp 3 avoids the snap fit 21. . In other words, if the lamp 3 is to be replaced in the irradiation position state of FIG. 15, the lamp 3 hits the snap fit 21 and cannot be replaced. Therefore, the lamp 3 is moved in the direction where there is no snap fit 21 and the lamp 3 is replaced. According to this, since the lamp 3 can be replaced without removing the functional section 9 from the design section 7, workability of lamp replacement can be improved.

  The lamp replacement in the second embodiment is easier to work than in the first embodiment because the lighting device is removed from the ceiling of the vehicle, the lamp 3 is moved to the replacement position, the lamp 3 is replaced, and then the lighting device is mounted again. It takes time and effort. However, when the lamp 3 is replaced together with the work for removing the lighting device from the ceiling, such as inspection and repair of the lighting device, the lamp 3 can be replaced without removing the design portion 7 and the functional portion 9, so that the lighting device is inspected and repaired. It is possible to improve the workability of replacing the lamp during the operation.

  In contrast to the second embodiment, a boss can be formed in the functional part 9 and a hole for axially stopping the boss can be formed in the design part. Moreover, it can replace with a hole and can form the recessed part which axially stops a boss | hub.
