Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a lighting fixture including a shade with a handle, such as a desk lamp or bed lamp.

[Background Art] Conventionally, desk lamps for tabletop work, hospital bed lamps, and the like have been provided in which a shade having a handle is attached to the tip of a flexible arm. The shade is formed into a bottomed cylindrical shape with one end face closed and the other end face open, and is integrally formed by a spatula drawing process or the like.

As shown in FIGS. 3 and 4, conventionally provided bed lamps include a bottomed cylindrical shade 10 whose upper end is closed and whose lower end is open.
A configuration in which a lamp 25 is disposed inside is common.
The lamp 25 is generally an incandescent lamp and is held in the lamp socket 24.
is attached to a socket base 22 fixed within the shade. This socket base 22 is attached to the shade 10 by a fixing screw 23 inserted from the outside of the shade 10.
Therefore, the fixing screw 23 is exposed on the outer circumferential surface of the shade 10, resulting in a problem that the appearance is poor. Further, since the lamp 25 is an incandescent lamp and requires heat radiation, the heat radiation hole 28 is formed in the upper part of the shade 10, but there is also a problem that there is a lot of light leakage from the heat radiation hole 28.

To solve these problems, as shown in FIGS. 5 and 6, a recess 21 is formed on the upper end surface of the shade 10, and the recess 21 is covered with a lid 14. provided. That is, the fixing screw 23 for attaching the socket base 22 to the bottom of the recess 21 is exposed, and the heat radiation hole 28 is formed, and the exposed portion of the fixing screw 23 and the heat radiation hole 28 are covered with the cover body 14. This prevents it from being exposed to the outside. Here, the heat radiation hole 28 has a shape that allows it to be attached to a hanging ceiling rosette, as shown in FIG. 6b. A mounting bracket 26 is attached to the inner peripheral surface (lower surface) of the lid body 14 by spot welding or the like.
is fixed, and this mounting bracket 26 is attached to shade 1.
Shade 1 with mounting screw 27 inserted from inside of
By fixing it to 0, the lid 14 can be attached to the shade 10 without exposing the attachment screw 27 to the outside. Mounting bracket 26
The cover 14 is attached to the shade 10 with the circumference of the cover 14 being slightly spaced from the circumferential wall of the recess 21, and heat is radiated through this gap. This configuration eliminates the defects in appearance of the configurations shown in FIGS. 3 and 4, but since the mounting screw 27 is screwed into the shade 10 from the inside, the shade 10 does not move in the axial direction. If the shield 10 is long or the diameter of the opening at the lower end of the shade 10 is small, it becomes troublesome to insert a tool into the shade 10 and attach the mounting screw 27.

Furthermore, in both the configurations shown in FIGS. 3 and 4 and the configurations shown in FIGS. 5 and 6, the outer periphery of the shade 10 is formed in a substantially U-shape by bending a pipe or a round bar. A handle 38 is attached. The handle 38 is fixed to the shade 10 by inserting the tips of both legs into the shade 10 and screwing nuts 38b into threaded portions 38a formed on the outer peripheral surfaces of the tips of both legs. Therefore, the nut 38b has to be tightened from the inside of the shade 10, which makes the tightening work difficult and tends to be insufficiently tightened, and the handle 38 may become loose after long-term use. There are many. Further, as described above, the shade 10 is formed by a spatula drawing process, but depending on the shape of the shade 10, the process of performing the dry drawing process increases, making manufacturing difficult. Furthermore, although the shade 10 is usually formed of an aluminum plate or a steel plate and is painted, it is not easy to paint the inner circumferential surface of the shade 10, and the coating is insufficient and rust is likely to occur. Sometimes.
Further, if an attempt is made to sufficiently coat the inner circumferential surface of the shade 10 to the inner part thereof, there is a problem that the coating film near the opening of the shade 10 becomes thick and so-called sagging of the coating occurs. Furthermore, it is necessary to connect the electric wire L ₁ introduced from the outside of the shade 10 and the electric wire L ₂ drawn out from the lamp socket 24 within the shade 10, which may cause the shade 10 to be long in the axial direction, or the lower end of the shade 10 If the opening is narrow, there will be a problem that connection work will be difficult. To solve this problem, the wires L ₁ and L ₂ will be made longer, so that the wires inside the shade 10 will be difficult to connect.
Problems arise in that the wires L ₁ and L ₂ may not behave properly, or the electric wires L ₁ and L ₂ may come into contact with the lamp 25 and become hot, which is dangerous.

In order to improve the mounting strength of the handle 38, it is possible to use a mounting body 41 in which the handle 38 is integrally formed with a ring-shaped main body 37 that is attached around the shade 10, as shown in FIG. , subject 37
If there is a gap between the inner circumferential surface of the shield 10 and the outer circumferential surface of the shade 10, the handle 38 will wobble as shown by the broken line in FIG. 8, and the purpose will not be fully achieved. Furthermore, if the inner circumferential surface of the main body 37 and the outer circumferential surface of the shade 10 are brought into close contact with each other, when the main body 37 is fitted into the shade 10, the shade 10 may be scratched by the corners of the main body 37, or the shade 10 may be coated. The film may peel off. To solve this problem, the main body 37 may be fixed to the shade 10 using a large number of coupling screws 17, but if there are many coupling screws 17, the number of parts increases and the appearance deteriorates. On the other hand, as shown in FIG. 9a, the shade 10
It is also conceivable to form a concave groove 42 around the periphery of the mounting body 41, but in this case, the main body 37 of the mounting body 41 may be divided, or the main body 37 of the mounting body 41 may be separated as shown in FIG.
7 had to be opened, and in order to combine the open parts, the external shape deteriorated,
Additionally, the joint may become loose, so this is not a good solution.

[Purpose of the invention] The present invention has been made in view of the above-mentioned points, and its purpose is to form the shade by a pair of divided bodies divided in the axial direction. Fixing work, painting work, and connecting wires can all be done easily from the inside of the
Moreover, by integrally forming the handle on the combined body that connects the pair of divided bodies forming the shade, the attachment strength of the handle is increased.Furthermore, the main body of the combined body is formed in a ring shape, and To provide a lighting fixture whose external shape is not deteriorated by forming a shade into a pair of divided bodies while fitting into a groove formed in the lighting fixture.

The shade has a first divided body on one end side in the axial direction, a second divided body on the other end side in the axial direction, and a main body formed in a band shape spanning the entire circumference in the circumferential direction of the shade. It consists of a connecting body that connects the divided body and the second divided body,
The first divided body and the second divided body partially overlap each other, and a groove is formed on the outer peripheral surface of the overlapping part, and in the groove, the main body of the combined body connects the outer peripheral surface to the first divided body. The second divided body is fitted so as to be substantially flush with the outer circumferential surface of the second divided body, and the combined body, the first divided body, and the second divided body are connected by a fixing device such as a screw, and the combined body is The main body is integrally provided with a handle, and by forming the shade with a first divided body and a second divided body divided in the axial direction, it is possible to fix the shade from the inside. , painting work, electrical wire connection work, etc. can be done with the shade disassembled,
Moreover, by integrally forming the handle on the joint body that connects the first divided body and the second divided body, the mounting strength of the handle is increased compared to the conventional structure in which the handle is fixed with a nut from the inside of the shade. Make it bigger, and
By forming the shade with a pair of divided bodies and forming a concave groove into which the combined body fits in the joining part of both divided bodies,
This is intended to improve the external appearance. In particular, a part of the first divided body and the second divided body overlap,
By joining the main body of the combined body to this overlapping part, the thickness of the part of the first divided body and the second divided body where the combined body provided with the handle is joined becomes large, and Coupled with the fact that the main body is fitted to the
It can be firmly attached to the divided body and the second divided body without wobbling. Further, since the outer circumferential surface of the main body of the combined body and the outer circumferential surfaces of the first divided body and the second divided body are approximately flush with each other, and no protruding parts other than the handle are formed on the surfaces, dust can accumulate. It has a difficult structure.

(Example) As shown in FIGS. 1 and 2, shade 10
is a first divided body 11 on one end side in the axial direction, a second divided body 12 on the other end side in the axial direction, and a connection that joins the first divided body 11 and the second divided body 12. The body 13 is formed into a bottomed cylindrical shape having an axis in the vertical direction. The first divided body 11 is formed into a bottomed cylindrical shape with a closed upper end surface and an open lower end surface, and a recess 21 is formed in the center of the upper end surface. A cover plate 14 is attached to cover the area. A socket base 22 is attached to the bottom wall of the recess 21 on the inner peripheral surface side of the shade 10.
It is fixed to the shade 10 by a fixing screw 23 which passes through the socket base 22 from the inside of the 0 and screws into the bottom wall of the recess 21. A lamp socket 24 is attached to the lower end of the socket base 22, and a lamp 25 made of an incandescent lamp is held in the lamp socket 24. Furthermore, a heat radiation hole (see 28 in FIG. 6) is formed in the bottom wall of the recess 21. A mounting bracket 26 is fixed to the lower surface of the lid plate 14 by spot welding or the like, and the mounting bracket 26 is screwed into the mounting bracket 26 from the inside of the shade 10 through the bottom wall of the recess 21. It is fixed to the shade 10. That is, the fixing screw 23, the heat radiation hole, and the mounting screw 27 are covered by the cover plate 14 and are not exposed to the outside. A slight gap is formed between the circumference of the cover plate 14 and the circumferential wall of the recess 21, and the hot air generated by the lamp 25 is radiated outside through the heat radiation hole through this gap. First divided body 11
A step portion 31 is formed at the lower end of the step portion 3.
The portion below 1 is a small diameter portion 32. Two approximately inverted L-shaped coupling holes 33 are formed in the small diameter portion 32 and are open facing the lower end edge of the first divided body 11 and whose upper portions extend in the circumferential direction of the first divided body 11 .

On the other hand, the second divided body 12 has an inner flange 1 on the lower edge.
5 is extended, and an opening 16 is formed in the center of the inner flange 15 to take out the luminous flux from the lamp 25. A step portion 34 is formed at the upper end of the second divided body 12, and a small diameter portion 35 is formed above the step portion 34. The small diameter portion 35 is formed so that its outer circumferential surface closely contacts and overlaps the inner circumferential surface of the small diameter portion 32 of the first divided body 11 . In addition, the small diameter portion 35 has a generally L-shaped coupling hole 3 which is open facing the upper end edge of the second divided body 12 and whose lower part runs in the circumferential direction of the second divided body 12.
6 is formed in two places. The coupling hole 33 of the first divided body 11 and the coupling hole 36 of the second divided body 12 are as follows:
They are formed at positions corresponding to each other, and are formed to run in opposite directions to each other in the circumferential direction.

The combined body 13 is formed of aluminum die-casting or the like, and has a ring-shaped main portion 3 that fits around the entire circumference of the small diameter portion 32 formed in the first divided body 11.
7, and the main part 3 with both leg pieces fixed to the main part 37.
7 and a substantially U-shaped handle 38 integrally formed therewith. That is, the wall thickness of the main part 37 is set to be approximately equal to the step of the step part 31 of the first divided body 11, and the inner circumferential surface of the main part 37 is set to be approximately equal to the outer circumference of the small diameter part 32 of the first divided body 11. It is designed to adhere to the surface.
Two connecting pins 39 are provided at appropriate locations on the inner peripheral surface of the main portion 37.
are provided in a protruding manner to correspond to the coupling holes 33 and 36. Therefore, the coupling pins 39 are introduced into the coupling holes 33 and 36 of the first divided body 11 and the second divided body 12, and the first divided body 11 and the second divided body 12 are connected to each other in the shade 10. When rotated in opposite directions around the vertical axis, the first divided body 11 and the second divided body 1
2 are coupled via the coupling body 13.
That is, the first divided body 11 and the second divided body 12
The main portion 37 of the combined body 13 fits into the groove 42 formed by the overlapping portion of the small diameter portions 32 and 34, and it is possible to prevent the combined body 13 from wobbling with respect to the shade 10. By the way, in this state, since the first divided body 11 and the second divided body 12 rotate in the circumferential direction, the main portion 37 of the combined body 13 and
If the coupling screw 17 as a fixture is inserted through the small diameter part 33 of the first divided body 11 and the small diameter part 36 of the second divided body 12, and the nut 18 is screwed into the coupling screw 17, the first The divided body 11, the second divided body 12, and the combined body 13 are reliably combined. Here, since the coupling screw 17 is inserted from the outside of the shade 10, the tightening operation is easy and reliable tightening can be performed. Connecting pin 3
9 and one pair of coupling screws 17 are provided, but the function can be achieved with at least one pair of each.

As described above, the shade 10 is divided into the first divided body 11
and the second divided body 12, the lid plate 14 can be attached to the socket base 21, the inner peripheral surface of the shade 10 must be painted, and the electric wires and lamp socket introduced from the outside can be attached to the lid plate 14 with the same vertical dimensions. In connection work with electric wires drawn out from 24, the work can be done with a small depth of the work member and a large opening diameter, and as a result, the work becomes easier and the coating film can be made uniform. Further, the handle 38 is formed integrally with the main part 37 of the combined body 13 attached to surround the circumference of the shade 10, and the main part 37 is formed at a stepped portion of the first divided body 11 and the second divided body 12. Since it fits into the groove 42 formed by the handles 31 and 34, there is an advantage that the fixing strength of the handle 38 to the shade 10 is extremely high.

[Effects of the invention] As described above, the present invention is a lighting fixture in which a lamp is housed in a cylindrical shade, in which the shade has a first divided body on one end side in the axial direction and a first divided body on the other end side in the axial direction. Consisting of a second divided body on the end side, and a combined body that has a main body formed in a band shape over the entire circumference of the shade and connects the first divided body and the second divided body, The first divided body and the second divided body partially overlap each other, and a groove is formed on the outer circumferential surface of the overlapping part. The combined body, the first divided body, and the second divided body are combined, and the main body of the combined body is integrally provided with a handle, and the shade is divided into a pair of divided bodies in the axial direction. Since the shade is formed with The conventional structure is such that the handle is integrally formed with the combined body that is attached to the shade, and the main part of the combined body provided with the handle is fitted into a groove formed on the circumferential surface of the shade, so that the handle is fixed with a nut from the inside of the shade. This has the advantage that the attachment strength of the handle is greater than that of the Furthermore, since the shade is divided into two parts, it is possible to create shades with complex shapes.Especially, since both the divided bodies are attached to the main part of the combined body that has a handle, it is possible to create a shade with a complicated shape. There is no need to form cutouts, etc., and there is an advantage that the external shape is improved. Moreover, by overlapping a part of the first divided body and the second divided body and joining the main body of the combined body to this overlapping part, the handle can be easily attached to the first divided body and the second divided body. The thickness of the part where the joined body is joined becomes larger, and this combined with the fact that the main body is fitted into the groove, causes the joined body on which external force is applied to become thicker between the first divided body and the second divided body. This has the effect that it can be firmly attached to the divided body without rattling.
Further, since the outer circumferential surface of the main body of the combined body and the outer circumferential surfaces of the first divided body and the second divided body are approximately flush with each other, and no protruding parts other than the handle are formed on the surfaces, dust can accumulate. It also has the advantage of being difficult.
