[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a lighting device in which a globe is attached to a main body via a V spring.

[0002]

[Prior art]

 In this type of luminaire, the engagement tool that is in engagement with the V spring is generally formed of a metal plate. That is, as such an engaging tool, one formed by cutting and raising from a support made of a metal plate attached to the opening edge of the globe, or a support made of a metal plate attached to the opening edge of the globe. Since a metal plate supported by screws is used in the above, there is no particular problem in the support structure of the engaging tool for the supporting tool. On the other hand, those in which the engaging tool is formed of a wire rod are as described in Japanese Utility Model Laid-Open Nos. 57-122618 and 62-17017.

[0003]

[Problems to be solved by the device]

 Japanese Utility Model Application Laid-Open No. 57-122618 discloses a structure in which the upper end of an engaging tool made of a closed-loop wire is attached to a tunnel-shaped extruded part formed on a support, but this is an impossible method. . In Japanese Utility Model Laid-Open No. 62-17017, it is described that a ring-shaped connecting portion is provided on the support, but it is virtually impossible to provide the connecting portion in a ring-like shape, and further, a wire rod is used. It is unclear whether the engagement tool is in a closed loop shape or an open loop shape, and it is unknown how the engagement tool is attached to the support tool. When adopting an engaging tool made of such a wire rod, it is necessary to devise a considerable amount of support structure for the supporting tool, it is easy to install, and moreover, it is stable even if force is applied by the up and down operation of the glove. Must be supported. The present invention was made by focusing on such a problem to be solved for the first time, and fundamentally improved the support structure for the support of the engaging tool made of the wire material in the engaging relationship with the V spring. It is an object of the present invention to provide a lighting device that is easy to install and that can be stably supported even when a force is applied by operating the glove up and down.

[0004]

[Means for Solving the Problems]

 In the present invention, the glove is attached to the main body via the support attached to the opening edge of the glove, the engagement tool supported by the support, and the V spring engaged with the engagement tool. The engaging member is composed of an open-loop spring wire rod having a bifurcated and vertical shape on the side supported by the support member, and the engaging member is attached to the upper end of each vertical portion in a direction away from each other. The engaging member is formed between a pair of cut-and-raised pieces, each of which is formed with a bent bent portion, and which is cut and raised so as to have an L-shaped cross section in a direction facing each other on the inner side of the support member. Each of the vertical parts is attached, and each of the bent parts is located between the upper edge of the cut-and-raised piece and the lower edge of the inward convex part formed at the upper end of the inner part of the support. It constitutes a fixed lighting fixture. The protrusions include those formed by cutting and raising from the support, but they may be formed as bulges bulged from the support. Further, the engagement tool may be engaged with the V spring so as to slidably sandwich both legs of the V spring, and the intermediate winding part of the V spring may be supported by a hooking tool fixed to the main body. Further, the engagement tool is engaged with the V spring so as to hold the intermediate winding portion of the V spring, and is engaged with the V spring so as to slidably sandwich both legs of the V spring. May be provided on the main body. The “V spring engaged with the engagement tool” defined in claim 1 is a definition including both cases.

[0005]

[Action]

 According to the present invention, by squeezing the side of the engagement tool supported by the support tool against the spring property, each vertical portion of the engagement tool is separated from the pair of cut and raised pieces of the support tool. It is easily attached between the engaging members, and the engaging member is stably supported without being displaced inward and outward. Then, each bent portion of the engaging member is positioned between the upper edge of the cut-and-raised piece and the lower edge of the inward convex portion formed at the upper end of the inner portion of the support member. Therefore, even if a force is exerted by the operation of moving the glove up and down, the engagement tool is stably supported without being vertically displaced with respect to the support tool. In addition, if the convex portion is formed by cutting and raising from the support, there is a risk of injury when touched with a hand, but if it is formed as a bulge portion, such a possibility is substantially reduced. Will be resolved.

【Example】

 Next, an embodiment of the present invention will be described, but it is merely a concrete example adopted based on the present invention, and the present invention is not limitedly interpreted based on matters specific to the embodiment. Of course, the technical scope of the present invention should be determined based on the matters shown in the claims or the matters substantially equivalent to the matters.

In the lighting equipment of the illustrated embodiment, a globe 1 made of synthetic resin has a support tool 2 made of a metal spring plate attached to an opening edge of the globe 1, and an engagement tool 3 supported by the support tool 2. And a V spring 4 made of a metal spring wire that is engaged with the engagement tool 3, and is attached to the main body 5. The engagement tool 3 is made of an open-loop metal spring wire having a bifurcated and vertical shape on the side supported by the support tool 2, and is folded at the upper ends of the respective vertical portions 6 so as to be bent in directions away from each other. The engaging member is formed between a pair of cut-and-raised pieces 8 each having a curved portion 7 formed therein, and which are cut and raised so as to have an L-shaped cross section in a direction opposite to each other on the inner side of the support member 2. Each of the vertical portions 6 of 3 is attached, and each of the above-mentioned bent portions 7 is located below the upper edge of the cut-and-raised piece 8 and the inwardly-directed convex portion 9 formed on the upper end of the inner portion of the support tool 2. Positioned between the edge. The protrusions 9 include those formed by cutting and raising from the support tool 2, but are preferably formed as a bulge portion bulged from the support tool 2 as illustrated.

Explaining the engagement relationship between the engagement tool 3 and the V spring 4 in detail, the engagement tool 3 is engaged with the V spring 4 so as to slidably sandwich both foot portions 10 of the V spring 4. More specifically, the engagement tool 3 projects horizontally inward from the lower end of each vertical portion 6 thereof and has a wide portion 11 on the inner end side thereof, and the V spring 4 is provided on both inner edges of the wide portion 11 at both inner edges thereof. It is engaged with the V spring 4 so as to slidably sandwich the both foot portions 10. The intermediate winding portion 12 of the V spring 4 is supported by a hook 13 which is fixed to the main body 5 with screws or other appropriate means.

To describe another structure, the support 2 is expanded as shown in FIG. 3 against the spring property, so that the vertical portion 14 of the opening edge on the upper surface side of the globe 1 and this vertical portion. The horizontal portion 15 extending outward from the lower end of the portion 14 is composed of a metal spring plate folded back in a double L-shape that is sandwiched between the vertical portions 16 and 17 inside and outside the support 2. The upper and lower horizontal pieces 18 and 19 are pinched by the vertical portion 14, and the upper and lower horizontal pieces 18 and 19 are pinched by the horizontal portion 15, and there is a gap between the lower surface of the folded portion 20 of the support 2 and the upper end of the vertical portion 14. 21 is provided. In addition, the bulging projections 9 and the bulging portions 22 and 23 that are separated from the surface of the globe 1 are formed on the upper ends of the vertical pieces 16 and 17 of the support tool 2 and the inner ends of the lower horizontal pieces 19 of the support tool 2. Are formed respectively.

In addition, when the insect-proof packing 25 made of a flexible material is attached to the lower surface of the main body 5 inside the bent portion 24 formed around the main body 5, the globe 1 is raised and attached to the main body 5. Then, the upper end of the support 2, that is, the upper surface of the folded portion 20 is pressed against the insect-proof packing 25. The V spring 4 may be in an upside-down state from that shown in the figure. In this case, the engagement tool 3 is engaged with the V spring 4 so as to hold the intermediate winding portion 12 of the V spring 4. For example, the engaging tool 3 is projected horizontally inward from the lower end of each vertical portion 6 thereof, and there is a substantially inverted U-shaped hooking portion formed upward at the inner end thereof. It may be assumed that the intermediate winding portion 12 of the V spring 4 is engaged and held. In this case, the structure of the hook 13 on the lower surface of the main body 5 is also changed so that the hook 13 is engaged with the V spring 4 so as to sandwich the both feet 10 of the V spring 4 in a slidable manner. .

In the illustrated embodiment, in order to mount the glove 1 on the main body 5, the V spring 4 is attached to the engaging member 3 and the bent portions 26 such as winding portions at both ends of the V spring 4 are provided. After pulling up to the extent that it can be hooked on both ends of the wide width portion 11, insert the intermediate winding portion 12 from the outer end of the hook 13 and hook the V spring 4 on the hook 13, and then lightly push up the globe 1. The elastic expansion force of both foot portions 10 of the V spring 4 acts on the wide width portion 11 to raise the globe 1, and the globe 1 is attached to the main body 5 as shown in FIG. When removing the glove 1, the glove 1 may be pulled down against the elastic expansion force of both legs 10 of the V spring 4, and then the intermediate winding portion 12 of the V spring 4 may be removed from the hook 13.

According to the present embodiment, the vertical portion 6 of the engaging member 3 is supported by the support member 2 of the engaging member 3 by compressing the side supported by the supporting member 2 against the spring property. It is easily attached between the pair of cut-and-raised pieces 8 of the tool 2, and the engaging tool 3 is stably supported without being displaced inward and outward. Each bent portion 7 of the engagement tool 3 is located between the upper edge of the cut-and-raised piece 8 and the lower edge of the inwardly projecting portion 9 formed at the upper end of the inner portion of the support tool 2. Since the position of the engagement tool 3 is set to 1, the engagement tool 3 is stably supported without being vertically displaced with respect to the support tool 2 even when a force due to the vertical operation of the globe 1 is applied. Also, if the convex portion 9 is formed by cutting and raising from the support tool 2, there is a risk of injury when touched with a hand, but if it is formed as a bulging portion, such a possibility is substantially. Will be resolved.

Further, the support tool 2 expands against the spring property so that it is not pinched by the vertical portion 14 at the opening edge of the globe 1 and the horizontal portion 15 extending outward from the lower end of the vertical portion 14. It is composed of a metal spring plate folded back into a double L-shape, and a gap 21 is provided between the lower surface of the folded portion 20 of the support tool 2 and the upper end of the vertical portion 14. When the tool 2 is attached to the opening edge of the globe 1, it can be easily attached due to the existence of the gap 21. In most cases, the glove 1 is formed of a synthetic resin sheet into a predetermined shape by vacuum forming, pressure forming, or the like. At that time, the surplus portion formed by projecting at the opening edge is cut to obtain the final product. As a result, the height of the vertical portion 14 is likely to vary due to variation in cut. However, even if there is variation in the height of the vertical portion 14 of the opening edge of the globe 1, the gap 21 exists, so that the upper end of the vertical portion 14 sticks to the lower surface of the folded portion 20 of the support tool 2. This prevents the support tool 2 from being difficult to attach to the opening edge of the globe 1. Thus, the vertical pieces 16 and 17 inside and outside the support 2 are clamped to the vertical portion 14, and the upper and lower horizontal pieces 18 and 19 are clamped to the horizontal portion 15 so that the opening edge of the glove 1 is closed. It can be mounted well on.

Further, bulging convex portions 9 and bulging portions spaced apart from the surface of the globe 1 at the upper ends of the vertical pieces 16 and 17 of the support tool 2 and the inner ends of the lower horizontal pieces 19 of the support tool 2. Since the parts 22 and 23 are respectively formed, it is possible to easily uniformly attach the vertical pieces 16 and 17 of the support tool 2 to the vertical part 14 of the glove 1 that are in close contact with each other. The portion of the horizontal piece 19 on the side that should be in close contact with the horizontal portion 15 of the globe 1 can be easily adhered uniformly, and the attachment of the support tool 2 to the opening edge of the globe 1 is further improved. Since there is the above-mentioned gap 21, if the upper horizontal piece 18 does not exist at all, the mounting state of the support tool 2 may be unsteady, which is uncomfortable. The horizontal piece 18 may be considerably shorter than that shown, as rattling does not substantially occur.
