Description

  The present invention relates to a lighting fixture mainly installed on a ceiling surface.

  A first conventional example (see, for example, Patent Document 1) shows a shade-type lighting fixture as shown in FIG. This lighting fixture includes a fixture main body 51 arranged on the lower surface of the ceiling, a ring-shaped suspension member 52 fixed to the lower surface side of the fixture main body 51, and a shade 53 as a light distribution control member arranged on the lower surface side thereof. The hook 53 is fixed to the periphery of the shade 53, and a hook 54a at the tip extends inward and is bent.

  The ring-shaped suspension member 52 is formed on the lower side of the instrument main body 51 with a wire rod or the like, and forms a gap between the instrument main body 51 and is fixed so as to be substantially parallel to the lower surface of the instrument main body 51.

  The hook member 54 is formed by bending both ends of the sheet metal. One end of the hook member 54 abuts the inner surface of the shade 53 and is fixed with a screw or the like, and the other end is a hook piece 54 a that is hooked on the suspension member 52.

  The hook members 54 are usually provided at three positions with a pitch of approximately 120 degrees with respect to one shade 53, and one end screw or the like fixed to the surface of the shade 53 in contact with the inner surface of the shade 53. A decoration 55 is provided in order to conceal and improve the appearance.

  A second conventional example is shown in FIG. This shade hanging type lighting fixture includes an appliance main body 61 arranged on the lower surface of the ceiling and a locking portion 62a at the tip, and extends outwardly of the appliance main body 61 and adheres to the appliance main body 61 obliquely downward. A pair of hook members 64 provided with a plurality of hung members 62, a shade 63 arranged on the lower surface side of the instrument body 61, and a hook piece 64a hooked to the hook portion 62a of the hook member 62. It is formed.

  The suspension member 62 has a locking portion 62a at the tip thereof bent into a substantially U shape.

Further, the pair of hook members 64 provided with the hook pieces 64a hooked to the hook portions 62a of the suspension member 62 is bent into the substantially U-shape by bending the side pieces 64b at both ends of the hook pieces 64a. A shaft piece 64c that is coaxially positioned at the end of the both side pieces 64b and is bent outward is formed. The hook member 64 is attached to the shade 63 by a pressing member 66 so that the hook pieces 64a of the pair of hook members 64 are substantially parallel and are rotatable about the two shaft pieces 64c. 65 is a decoration.
Japanese Unexamined Patent Publication No. 8-171807

  In general, in lighting fixtures that hang a shade on the fixture body, the shade does not come off accidentally and does not fall off or deform, making the gap between the ceiling surface and the shade as small as possible, giving a feeling of close contact with the ceiling, In addition, it is desirable that the shade can be easily attached and detached, and that light unevenness and shadows do not appear on the ceiling or the shade surface.

  However, in the first conventional example configured as described above, the hooking member 54 is formed of a sheet metal and is fixed to the shade 53, and thus is easily deformed by an external force. Increasing the width of the hook member 54 to increase the strength causes the hook member 54 to be shaded on the ceiling or shade surface. Further, since there are at least three hook members 54, the detachability of the shade 53 is poor.

  In the second conventional example, as a procedure for attaching the shade 63, first, the hook member 64 on one side of the shade 63 is hooked on the suspension members 62 on one side of the instrument body 61, and then the same operation is performed on the other side. I do. At this time, the suspension member 62 is disposed at two locations on one side, and the shade 63 is larger than the instrument main body 61. Therefore, when the gap between the ceiling and the shade 63 is small, when attaching the shade 63, Since the suspension member 62 is not visible and the position is not known, it is difficult to aim at hooking the hook member 64 on the suspension member 62, and it is difficult to attach the shade 63.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a lighting apparatus in which a shade can be easily attached and detached and the shade does not easily fall off.

  The luminaire of the present invention has a lamp socket on which the fixture body has a hanging member formed with a hook hole on both sides and a lamp is mounted. The light distribution control member is provided on the front surface of the instrument body with hook members that are hooked on the hook holes on both sides. The hook member includes a hook piece that extends inward from both sides of the light distribution control member and is slidably hooked into the hook hole, and a stopper piece that extends in a direction away from the instrument body from the tip of the hook piece. And have. A pair of the suspension members is separated from each other so that the hooking piece of one of the hooking members can be slid into the hooking hole and the hooking piece of the other hooking member can be attached to and detached from the hooking hole. The interval between the hook members and the length of the hook piece are set.

  The said structure WHEREIN: The width | variety of the said hook hole and the width | variety of the said hook piece are set so that the said light distribution control member may not rotate centering on the line | wire which connects the said hook hole of the both sides of the said instrument main body.

  In the above configuration, the anti-slip piece extends downward in the range of about 40 to 90 degrees with respect to the horizontal in a state where the light distribution control member is hooked on the hook member in a horizontal posture.

  The said structure WHEREIN: The said suspension member is formed so that it may hang down from the both sides of the said instrument main body to the outer side of the said instrument main body.

  The said structure WHEREIN: The said light distribution control member is a shade, The planar shape is larger than the planar shape of the said instrument main body.

  In the above configuration, the hooking piece is inclined upward from the proximal end to the distal end.

  According to the lighting apparatus of the present invention, the hook piece of one of the hook members can be slid into the hook hole and the hook piece of the other hook member can be attached to and detached from the hook hole. The light control member can be easily attached and detached, and the light distribution control member is unlikely to fall off carelessly.

  By setting the width of the hooking hole and the width of the hooking piece, it is possible to easily prevent the light distribution control member from rotating.

  Since the stopper piece is directed downward in the range of about 40 to 90 degrees with respect to the horizontal, for example, even when a horizontal force is applied with the shade attached, the shade is difficult to come off and a shadow is not easily projected on the shade.

  Since the suspension member is formed so as to hang down from both sides of the instrument main body to the outside of the instrument main body, the hook of the hook member is improved.

  Since the shade is larger than the instrument body, the hanging member and the hooking member are difficult to see from below, and the design is excellent.

  Since the hook piece is inclined upward from the base end to the tip end, for example, the shadow of the hook member is difficult to be projected onto the shade.

  The lighting fixture of the 1st Embodiment of this invention is demonstrated with reference to FIGS. The instrument body 1 is a ceiling-mounted type, and is attached to a hooking ceiling 11 of the ceiling 15. The fixture body 1 is provided with a lighting device, a bean bulb socket, a lamp socket 7 and the like, a bean bulb 12 is attached to the bean bulb socket, and an annular lamp 6 is attached to the lamp socket 7.

  The instrument body 1 has suspension members 3 on both sides, and the suspension member 3 bends the wire rod into a substantially U shape to form an intermediate piece 3b serving as a locking piece and side pieces continuous on both sides thereof. As shown in FIG. 1, the two side pieces are bent at their intermediate positions so that the tips approach each other in plan view, and are bent in a substantially inverted L shape as shown in FIG. Then, both ends of both side pieces of the pair of suspending members 3 are attached to both sides of the instrument main body 1 by attachments 13 such as screws, and the intermediate piece 3b is formed so as to hang down to the outside of the instrument main body 1, whereby the intermediate piece 3b A hook hole 3a is formed between the two side pieces. The intermediate piece 3b is positioned on the upper surface of the shade 2 in a state where the shade 2 described later is attached to the instrument body 1.

  The light distribution control member, for example, the shade 2 has a planar shape larger than that of the instrument body 1 and is disposed on the front surface of the instrument body 1 to cover the annular lamp 6 and the like. Hook members 4 are provided on both sides of the shade 2. The hooking member 4 is hooked in the hooking hole 3a of the hanging member 3. The hooking member 4 extends inward from both sides of the shade 2 and is slidably hooked on the hooking hole 3a, and from the tip of the hooking piece 4a. A detachment stop piece 4b extending in a direction away from the instrument body 1 and falling is formed. The hook member 4 is bent into a substantially U shape by a wire, and the hook ends 4a are formed near the base ends on both sides of the U shape, the U-shaped stoppers 4b are formed at the tip and the middle of both sides, and the hook pieces 4a. The support pieces 4c are extended in opposite directions from both ends, and the tips of the support pieces 4c are fixed at the corners of the shade 2 by screws 14 or the like, and the support pieces 4c do not rotate around the longitudinal axis. I am doing so. As shown in FIG. 3, the stopper piece 4b is bent downward at an angle θ with respect to the hook piece 4a in a horizontal position when viewed from the front. The range of the angle θ is preferably about 40 to 90 degrees. Further, the width of the hook hole 3a and the width of the hook piece 4a are set to such a length that the shade 2 does not easily rotate around the line connecting the hook holes 3a on both sides of the instrument body 1. Reference numeral 5 denotes a decoration provided at the corner of the shade 2.

  Then, the distance between the pair of suspension members 3 is such that the hook piece 4a of one hook member 4 can slide into the hook hole 3a and the hook piece 4a of the other hook member 4 can be attached to and detached from the hook hole 3a. The lengths of the pair of hook members 4 and hook pieces 4a are set.

  4 to 8 show the procedure for attaching the shade 2. One of the hook members 4 of the shade 2 is inserted into the hook hole 3a of the suspension member 3 from the outside of the instrument body 1 as shown by the arrow in FIG. The shade 2 is lifted to substantially horizontal as indicated by the arrows in FIGS. 5 and 6, and the shade 2 is slid in the direction of the other suspension member 3 from the suspension member 3 hooked above. As shown in FIGS. 7 and 8, the other hooking member 4 is inserted into the hooking hole 3 a of the other hanging member 3 from the outside of the instrument main body 1 and hooked. If the operation of reversing the attachment of the shade 2 is performed, the shade 2 can be removed.

  According to the first embodiment, there are two hook holes 3a, and the shade 2 can be easily attached and detached as compared with the first conventional example having three places. Further, since the hooking hole 3a is large, the shade 2 can be easily attached and detached as compared with a method in which the hooking piece 64a is hooked on a plurality of locking parts 62a bent in a substantially U shape as in the second conventional example. The suspending member 3 is formed of a steel wire, and light unevenness on the surface of the ceiling 15 and the shade 2 and the shadow of the suspending member 3 are difficult to appear.

  The hook member 4 is formed in such a length that the tip of the hook member 4 does not come into contact with the contents of the fixture body 1 such as the ring lamp 6 when the shade 2 is attached and detached, and is provided at the tip of the hook member 4. The intermediate piece 4b, which is a piece, makes it difficult for the shade 2 to come off even when a horizontal external force is applied with the shade 2 attached.

  The hook holes 3a and the hook pieces 4a have a width so that they do not rotate when the shade 2 is attached. The hook members 4 are respectively attached to the suspension members 3 on the side of the instrument body 1. Since one by one is opposed, the detachability of the shade 2 is better than that of the second conventional example. In the second conventional example, since there are a plurality of suspension members 62 on the instrument body 1 side so that the shade 2 does not rotate, it is difficult to aim at hooking the hook piece 64 on the suspension member 62, and it is difficult to attach the shade 2. .

  The intermediate piece 3b which is a locking piece of the suspension member 3 is formed so as to be substantially parallel to the ceiling 15 when the instrument main body 1 is attached. In addition, since the hooking piece 4a facing the hooking member 4 of the shade 2 is also substantially parallel, the shade 2 can be kept substantially parallel to the ceiling 15 even when the shade 2 is attached.

  When the hook member 4 is attached to the shade 2, the angle θ with respect to the hook piece 4 a of the stopper piece 4 b provided at the tip of the hook piece 4 a when viewed from the side is about 40 degrees or more and 90 degrees or less. It is formed to become. For this reason, even when a horizontal external force is applied to the shade 2 in a state where the shade 2 is attached, the shade 2 is difficult to come off due to the come-off prevention piece 4b. If only emphasis is placed on difficulty of detachment, 90 degrees is desirable. On the other hand, when the angle θ is about 40 degrees, the slip-off preventing piece 4b is separated from the shade 2, and thus it is difficult for a shadow to appear on the surface of the shade 2.

  Although the shade 2 is not inadvertently detached due to external forces such as vibrations, when removing the shade 2, pull the shade 2 in the direction in which the hook member 4 is disposed while lifting the shade 2 obliquely upward. In this case, the detachment stopper 4b serves as a guide, and the shade 2 can be easily removed.

  Further, when viewed in plan, the shade 2 is larger than the instrument main body 1, and therefore the suspension member 3 and the hook member 4 are both hidden by the shade 2 when the shade 2 is attached. For this reason, when it sees from the downward direction, the suspension member 3 and the hook member 4 become invisible, and it is excellent in the design property. At this time, since the through hole 3a of the suspension member 3 is large, the detachability of the shade 2 is not impaired.

  The suspension member 2 is formed so as to hang outward from the instrument body 1 from the proximal end to the distal end when viewed from the side. For this reason, when the shade 2 is hooked on only one of the suspension members 3 such as when the shade 2 is attached or detached, the hook piece is a point where the support piece 4c of the hook member 4 contacts the suspension member 3 as a fulcrum. There is an effect of reducing the deformation of the suspension member 3 by pressing the locking piece 4. In particular, when the bending angle θ1 of the suspension member 3 is 90 degrees or more as shown in FIG. 9, the shade 2 is perpendicular to the case where the bending angle θ1 of the suspension member 3 is about 90 degrees as shown in FIG. 10. Since the force does not act in the direction of the arrow in FIG. 10 due to the inclination of the shade 2 when it is in the posture, the suspension member 3 is not easily deformed.

  A second embodiment of the present invention will be described with reference to FIG. That is, in the first embodiment, the hooking piece 4a of the hooking member 4 is inclined upward from the base end to the tip when viewed from the side.

  As in the first embodiment, when the hooking piece 4a of the hooking member 4 is horizontal, the distance between the tip of the stopper piece 4b of the hooking member 4 and the shade 2 is small in a small lighting fixture. The shadow of the hook member 4 is easily projected on the shade 2.

  In the second embodiment, with the above configuration, the distance between the tip of the retaining piece 4b of the hooking member 4 and the shade 2 can be taken, and the shadow of the hooking member 4 is hardly projected on the shade 2.

  In addition to shades, light distribution control members include louvers and covers.
