DETAILED DESCRIPTION OF THE INVENTION

[0011] A shade and a lighting fixture according to an embodiment of the present disclosure will be described in detail below with reference to the drawings. However, the drawings described in the following embodiments are schematic diagrams, and the ratios of the sizes and thicknesses of the components do not necessarily reflect the actual dimensional ratios. Note that the configurations described in the following embodiments are merely examples of the present disclosure. The present disclosure is not limited to the following embodiments, and various modifications are possible depending on the design, etc., as long as the effects of the present disclosure can be achieved.

[0012] (1) Overview The shade 1 according to the embodiment includes a shade body 2 formed in a three-dimensional shape surrounding the light source B1, and an attachment member 3 for attaching the shade body 2 to a fixture body (socket A11) that supports the light source B1 (see FIGS. 1 and 2). Generally, a shade is a light-blocking device made of an opaque or diffusely transmissive material designed to prevent direct viewing of a light source such as a lamp. A globe is a device similar to a shade. A globe is a device made of a transparent or diffusely transmissive material that covers a light source such as a lamp to protect the light source, diffuse the light, or change the light color of the light source. Therefore, the shade 1 according to the embodiment is not limited to a typical shade, and may function as a globe.

[0013] The mounting member 3 has a fixing portion 30 that is fixed to the socket A11, and one or more hooking portions 31 that are hooked onto one or more hooked portions 20 provided on the shade main body 2 (see FIG. 3).

[0014] Thus, the shade 1 according to the embodiment can be attached to the fixture body (socket A11) simply by hooking the hooking portion 31 onto the hooked portion 20 of the shade body 2 (see FIG. 2). Therefore, the shade 1 according to the embodiment does not require the parts (support shaft and nut) required to attach the shade to the ring body (corresponding to the fixture body) as in the conventional example, and therefore the attachment structure to the fixture body (socket A11) can be simplified.

[0015] Furthermore, since the lighting fixture A1 according to the embodiment includes the fixture body (socket A11) and the shade 1 according to the embodiment, as described above, the mounting structure (of the shade 1) to the fixture body (socket A11) can be simplified.

[0016] (2)Details The shade 1 and lighting device A1 according to the embodiment will be described in detail below with reference to the drawings.

[0017] (2-1) Lighting equipment The lighting fixture A1 according to this embodiment (hereinafter simply referred to as lighting fixture A1) includes a socket A11, a plug A12, a cord A13, a support plate A14, and a flange A15 (see FIG. 1). A light source B1 is detachably attached to the socket A11. The light source B1 is a so-called bulb-shaped LED lamp. However, the light source B1 is not limited to an LED lamp and may be an incandescent lamp or a bulb-shaped fluorescent lamp, etc.

[0018] One end (lower end) of the cord A13 is electrically and mechanically connected to the socket A11, and the other end (upper end) of the cord A13 is electrically and mechanically connected to the plug A12.

[0019] The plug A12 is detachably attached to a wiring duct (also called a lighting duct). The plug A12 supports the socket A11 via a cord A13 and supplies power to the socket A11 via the cord A13. When the light source B1 is attached to the socket A11, it is electrically and mechanically connected to the socket A11 and lights up with the power supplied via the socket A11.

[0020] The support plate A14 fixes (supports) the socket A11 to the mounting member 3 of the shade 1 according to the embodiment (hereinafter, abbreviated as the shade 1), as will be described later.

[0021] The flange A15 is made of synthetic resin and has a truncated cone shape with an open top, and is configured to accommodate the plug A12 together with the excess length of the cord A13 (see FIG. 1).

[0022] Thus, the lighting fixture A1 is configured so that the shade 1 fixed to the socket A11 covers the light source B1 attached to the socket A11 (see FIG. 1).

[0023] (2-2) Shade The shade 1 includes a shade body 2 formed in a three-dimensional shape surrounding the light source B1, and an attachment member 3 for attaching the shade body 2 to a socket A11 that supports the light source B1 (see FIGS. 1-4). In this embodiment, the shade body 2 is made of a diffusely transparent material and is formed in a generally truncated cone shape with two open bottom surfaces (see FIG. 2). The diffusely transparent material forming the shade body 2 is, for example, a sheet-like member (hereinafter referred to as the sheet material) formed by laminating a sheet of translucent synthetic resin (such as polyethylene terephthalate) onto Japanese paper. However, the material forming the shade body 2 may be other than the sheet material described above. The shade body 2 may also be formed from a non-translucent material.

[0024] (2-2-1) Mounting parts The mounting member 3 has a fixed portion 30 that is fixed to the socket A11 and a plurality of (three in the illustrated example) hook portions 31 (see FIG. 3). The fixed portion 30 is formed in a sheet shape. A circular opening 300 is provided in the center of the fixed portion 30. The three hook portions 31 are formed integrally with the fixed portion 30 so as to protrude from the periphery of the fixed portion 30. The material forming the fixed portion 30 and the three hook portions 31 is the same as the material (sheet material) forming the shade body 2.

[0025] On the outer periphery of the fixing part 30, the portions sandwiched between the three hooking parts 31 are formed in an arc shape. However, since the centers of the arc-shaped portions are not concentric, the outer periphery of the fixing part 30 is neither a perfect circle nor an ellipse.

[0026] The hooking part 31 has a main part 310, a connecting part 311 that connects the main part 310 to the fixed part 30, and a groove (hereinafter referred to as a second groove 32) formed between the main part 310 and the fixed part 30 (see FIG. 3). The hooking part 31 also has an extending part 312 that extends from the main part 310 toward the second groove 32.

[0027] The main portion 310 is formed in a substantially semicircular plate shape. The connecting portion 311 connects one diametric end of the main portion 310 to the periphery of the fixed portion 30. However, both ends of the connecting portion 311 along the diametric direction of the main portion 310 are notched in an arc shape (see FIG. 3). The extending portion 312 extends from the other diametric end of the main portion 310 in a direction approaching the fixed portion 30. Furthermore, the tip portion of the extending portion 312 is formed wider than the portion excluding the tip portion of the extending portion 312. In other words, the connecting portion of the extending portion 312 with the main portion 310 is formed narrower than the tip portion. Furthermore, the tip portion of the extending portion 312 is formed in a substantially semicircular plate shape. The second groove 32 is formed in a rectangular shape surrounded by the periphery of the fixed portion 30, the main portion 310, the connecting portion 311, and the extending portion 312.

[0028] The three hook portions 31 are arranged at equal intervals along the outer periphery of the fixed portion 30. Each of the three hook portions 31 is bent at a connecting portion 311 in the thickness direction of the fixed portion 30 (see FIG. 4).

[0029] (2-2-2) Shade body A plurality of (three in the illustrated example) hooked portions 20 are provided on the upper portion of the shade main body 2 (see FIG. 2). Each of the three hooked portions 20 has a hole 200 penetrating the shade main body 2, a protrusion 201 protruding inward from the periphery of the hole 200 on the shade main body 2, and a groove (hereinafter referred to as a first groove 202) formed between the protrusion 201 and the periphery of the hole 200 (see FIGS. 10 and 11). The three holes 200 are formed by cutting and raising the protrusion 201 from the sheet material 21.

[0030] The protrusion 201 is formed in a semicircular plate shape (see FIG. 10). Therefore, the hole 200 is also formed in a semicircular shape. The first groove 202 is formed linearly along the diameter direction of the protrusion 201 at the connection portion between the protrusion 201 and the shade main body 2. One end of the first groove 202 is connected to the hole 200. A circular through-hole 203 is formed at the other end of the first groove 202 and at the end of the protrusion 201 (see FIG. 10). The three hook portions 31 are bent so as to tilt the respective protrusions 201 inward of the shade main body 2 (see FIG. 11).

[0031] The shade main body 2 is formed into a three-dimensional shape (approximately a truncated cone shape) by deforming the sheet material 21. However, the three-dimensional shape of the shade main body 2 is not limited to an approximately truncated cone shape, and may be a truncated cone shape, a cylinder shape, a sphere shape, an ellipsoid shape, or the like.

[0032] The sheet material 21 has a plurality of (three in the illustrated example) insertion grooves 210 and three insertion pieces 211 that are inserted into the three insertion grooves 210 one by one (see FIGS. 5A and 5B). FIG. 5A shows a front view of the sheet material 21, and FIG. 5B shows a rear view of the sheet material 21. Here, the shade main body 2 shown in FIGS. 1 and 2 is formed from a semicircular sheet material. However, the following description will be given assuming that the shape of the sheet material 21 is rectangular.

[0033] Of the three insertion pieces 211, the insertion piece 211 provided at the upper right corner of the sheet material 21 in FIG. 5B (hereinafter, may be referred to as the first insertion piece 211A) is formed by a single notch (groove 2120) provided at the corner portion of the sheet material 21 (see FIG. 7). One end of the groove 2120 in the longitudinal direction is open. The other end of the groove 2120 in the longitudinal direction is connected to a round hole 2121 that penetrates the sheet material 21. The groove 2120 and the round hole 2121 form the engagement portion 212.

[0034] Of the three insertion pieces 211, the insertion piece 211 on the left of the first insertion piece 211A in Fig. 5B (hereinafter may be referred to as the second insertion piece 211B) and the insertion piece 211 on the left of the second insertion piece 211B (hereinafter may be referred to as the third insertion piece 211C) are each formed in a region (a part of the sheet material 21) sandwiched between a pair of notches 2110 (see Figs. 5B and 6). Note that the tip of each pair of notches 2110 is connected to one of the four holes 2111 penetrating the sheet material 21.

[0035] (2-2-3) Shade body assembly process Next, with reference to FIGS. 5B to 9, the process of assembling the shade main body 2 using the rectangular sheet material 21 will be described.

[0036] The worker performing the assembly work (hereinafter referred to as the worker) crosses the left and right corners in FIG. 5B and rolls up the sheet material 21 so that the back surface of the sheet material 21 faces inward (see FIG. 6). Then, the worker inserts the first insertion piece 211A into the first insertion groove 210A from the outer surface (front) of the shade main body 2 toward the inside (back surface) (see FIGS. 7 and 8). The worker also inserts the second insertion piece 211B into the second insertion groove 210B from the outer surface (front) of the shade main body 2 toward the inside (back surface). The worker also inserts the third insertion piece 211C into the third insertion groove 210C from the outer surface (front) of the shade main body 2 toward the inside (back surface).

[0037] Next, the worker slides the first insertion piece 211A inserted into the first insertion groove 210A along the first insertion groove 210A to engage the engagement portion 212 with the periphery of the first insertion groove 210A (see FIG. 9). Specifically, the periphery of the first insertion groove 210A in the sheet material 21 is inserted into the groove 2120 of the engagement portion 212, and the edge of the round hole 2121 provided at the end of the groove 2120 engages with the edge of the hole 2100 provided at the end of the first insertion groove 210A (see FIG. 9). When the engagement portion 212 (edge ​​of the round hole 2121) is engaged with the first insertion groove 210A (edge ​​of the hole 2100), the edges of the holes 2111 connected to each pair of notches 2110 engage with the edges of the holes 2111 at both ends of the second insertion piece 211B and the third insertion piece 211C (see Figure 9).

[0038] The assembly of the shade body 2 is completed through the above steps.

[0039] Here, sheet material 21 is made by laminating sheet-shaped synthetic resin onto Japanese paper, which makes it stiffer (also called rigidity or stiffness) than single-piece Japanese paper. Therefore, the force that causes sheet material 21 to return to its original state from its rolled-up state balances with the force with which engaging portion 212 pulls first insertion piece 211A, thereby maintaining the three-dimensional shape (approximately a truncated cone shape) of shade main body 2. In other words, the shade main body 2 can be formed into a desired three-dimensional shape without using any components other than sheet material 21.

[0040] (2-2-4) Shade assembly process Next, with reference to FIGS. 10 to 15, the process of assembling the shade 1 by attaching the attachment member 3 to the shade main body 2 will be described.

[0041] First, the worker bends the protruding pieces 201 of the three hooked portions 20 toward the inside of the shade main body 2 (see Figs. 10 to 12). Note that Fig. 12 shows a partially omitted plan view of the inside of the shade main body 2 as seen from the lower opening.

[0042] The hooked portion 20 provided adjacent to the third insertion piece 211C overlaps with a part of the sheet material 21 (see FIG. 10). Therefore, the sheet material 21 forming the shade main body 2 has a substantially semicircular through-hole 213 provided at a position overlapping with the hooked portion 20 provided adjacent to the third insertion piece 211C (see FIGS. 5A and 5B). Therefore, the worker can insert the protruding piece 201 of the hooked portion 20 provided adjacent to the third insertion piece 211C through the through-hole 213 and bend it (see FIG. 11).

[0043] Next, the worker inserts the mounting member 3, with the three hooking portions 31 bent and raised, into the shade body 2 through the lower opening. Then, while rotating the mounting member 3 in the circumferential direction, the worker inserts the first grooves 202 of the three hooked portions 20 into the second grooves 32 of the three hooking portions 31 (see FIGS. 13A and 13B). Furthermore, the worker further rotates the mounting member 3 in the circumferential direction to hook the tip portions of the extension portions 312 of the three hooking portions 31 onto the end portion of the protrusion 201 (see FIG. 13B). Thus, by hooking the tip portions of the extension portions 312 of the three hooking portions 31 onto the end portion of the protrusion 201, the mounting member 3 becomes less likely to come off the shade body 2. Since the main portion 310 of the hooking portion 31 is larger than the hole 200 of the hooked portion 20, the hole 200 can be blocked when the mounting member 3 is attached to the shade body 2 (see FIG. 13B).

[0044] The above steps complete the assembly of the shade 1 (see Figures 14 and 15).

[0045] (2-3) Lighting fixture assembly process Next, a process for assembling the lighting fixture A1 by attaching the socket A11 to the shade 1 will be described.

[0046] The worker inserts the socket A11 into the opening 300 of the fixing part 30 through the opening at the top of the shade main body 2.

[0047] Next, the worker attaches the support plate A14 to the tip of the socket A11 protruding below the fixing part 30 through the opening at the bottom of the shade body 2. As a result, the socket A11 is attached to the mounting member 3 with the fixing part 30 sandwiched between the socket A11 and the support plate A14 (see FIG. 1).

[0048] The above steps complete the assembly of the lighting fixture A1.

[0049] (3) Advantages of the embodiment As described above, the shade 1 can be attached to the socket A11 simply by hooking the hooking portion 31 onto the hooked portion 20 of the shade body 2 (see Figure 2). Therefore, the shade 1 does not require the parts (support shaft and nut) required to attach the shade to the ring body (corresponding to the fixture body) as in the conventional example, and therefore the attachment structure to the socket A11 (fixture body) can be simplified.

[0050] Furthermore, since the lighting fixture A1 includes the socket A11 and the shade 1, as described above, the structure for attaching the shade 1 to the socket A11 (fixture body) can be simplified.

[0051] Here, the hooked portion 20 has a protruding piece 201 that protrudes inward from the shade body 2. On the other hand, the hooking portion 31 is formed integrally with the fixing portion 30, which is formed in a sheet shape, so as to protrude from the fixing portion 30 and is configured to be hooked onto the protruding piece 201.

[0052] Therefore, since the shade 1 has the hooked portion 20 formed integrally with the shade main body 2 and the hooking portion 31 formed integrally with the mounting member 3, the number of parts can be reduced and the mounting structure to the socket A11 (fixture main body) can be further simplified.

[0053] The hooked portion 20 further has a hole 200 formed by cutting and raising the protruding piece 201 from the shade body 2. The hooking portion 31 closes the hole 200 while being hooked onto the protruding piece 201.

[0054] Thus, the shade 1 can reduce the number of parts by cutting out the protruding piece 201 from the shade body 2, and can also prevent the appearance from being impaired by closing the hole 200 with the protruding piece 201.

[0055] Furthermore, the hooked portion 20 has a first groove 202 formed between the peripheral portion of the hole 200 in the shade body 2 and the protruding piece 201. The hooking portion 31 preferably has a main portion 310 inserted into the first groove 202, a connecting portion 311 connecting the main portion 310 to the fixed portion 30, and a second groove 32 formed between the main portion 310 and the fixed portion 30. The hooking portion 31 is hooked onto the protruding piece 201 with the second groove 32 engaged with the first groove 202.

[0056] Thus, the shade 1 can prevent the hooking portion 31 from coming off the protruding piece 201 by hooking the hooking portion 31 onto the protruding piece 201 with the second groove 32 engaged with the first groove 202.

[0057] The hook portion 31 further has an extension portion 312 extending from the main portion 310 toward the second groove 32. The tip portion of the extension portion 312 is formed to be wider than the portion excluding the tip portion of the extension portion 312. Furthermore, the boundary portion of the extension portion 312 between the tip portion and the portion excluding the tip portion is curved.

[0058] Thus, by hooking the extension portion 312 provided on the hook portion 31 onto the protrusion 201, the shade 1 can make it even more difficult for the hook portion 31 and the protrusion 201 to come off. Furthermore, the shade 1 has a curved boundary portion between the tip of the extension portion 312 and the portion excluding the tip, making it even more difficult for the hook portion 31 and the protrusion 201 to come off. Note that the hook portion 31 does not have to have the extension portion 312.

[0059] The shade body 2 is formed into a three-dimensional shape by deforming a sheet-like member (sheet material 21). The sheet material 21 has a plurality of insertion grooves 210 and a plurality of insertion pieces 211 that are inserted into the insertion grooves 210 one by one.

[0060] Thus, by inserting the multiple insertion pieces 211 into the multiple insertion grooves 210 one by one, the shade 1 can deform the shade main body 2 into a desired three-dimensional shape without using any parts other than the shade main body 2.

[0061] Furthermore, the sheet material 21 has engagement portions 212 that engage with the peripheries of the insertion grooves 210 of the sheet material 21 in a state where the insertion pieces 211 are inserted into the insertion grooves 210 one by one.

[0062] Thus, by engaging the engaging portion 212 with the periphery of the insertion groove 210, the shade 1 can maintain the three-dimensional shape of the shade body 2 without using adhesive or the like.

[0063] Furthermore, the multiple insertion pieces 211 are inserted into the multiple insertion grooves 210 from the outer surface of the shade body 2 toward the inside. Therefore, by hiding the multiple insertion pieces 211 inside the shade body 2, the shade 1 can prevent deterioration in its appearance.

[0064] (4) Variations Next, several modified examples of the shade 1 and lighting fixture A1 according to the embodiment will be described. However, the basic configuration of the shade 1 and lighting fixture A1 in each of the modified examples described below is the same as the basic configuration of the shade 1 and lighting fixture A1 according to the embodiment. Therefore, the same reference numerals will be used to designate components that are common or substantially common to the basic configuration of the shade 1 and lighting fixture A1 according to the embodiment, and illustrations and descriptions thereof will be omitted as appropriate. In the following description, "substantially common configuration" means a configuration that is slightly different in shape, size, etc., but has the same function.

[0065] (4-1) Variation 1 The shade 1 of the first modification is the same as the shade 1 of the embodiment. The lighting fixture A1 of the first modification includes an arm A17 that holds the fixture body (socket A11) and a base A16 that supports the arm A17 (see FIGS. 16A and 16B).

[0066] The base A16 is made of metal or synthetic resin and has a plate or box shape, and is fixed to a wall inside a room by means of screws or the like.

[0067] The arm A17 is formed into an L-shaped pipe from metal or synthetic resin. One end of the arm A17 is fixed to the base A16, and the other end of the arm A17 is attached to the socket A11. An electric cable for power supply is housed inside the arm A17. The electric cable is electrically connected to a power line drawn out from the wall. That is, the socket A11 is supplied with power from an external power source via the power line and the electric cable.

[0068] The shade 1 may be attached to the socket A11 so that the narrower opening faces upward (see FIG. 16A), or so that the wider opening faces upward (see FIG. 16B).

[0069] (4-2) Variation 2 The shade 1 of Modification 2 is the same as the shade 1 of the embodiment.
