  The present invention relates to a method for connecting a cover of a lighting fixture and a suspension member.

  Usually, a lighting fixture attached to a ceiling or a wall has a structure in which a cover is attached to a fixture main body which is a box containing a lamp. The cover is used for the purpose of reducing glare or improving appearance, and a cover using a member having translucency is often used. The instrument main body and the cover are attached via a suspension member obtained by processing a wire such as a V-shaped spring, and is devised so that it can be easily attached and detached. In order to prevent the cover from being pulled up suddenly by the spring action of the suspension member during the attachment / detachment work, for example, a deformed V-shaped spring, a braking device, etc. as disclosed in Patent Documents 1 to 3 have been developed. .

  The suspension member is coupled to the cover by a coupling member. As for the connecting member, as shown in Patent Document 4, the shape of the folded portion for locking the V-shaped spring is improved so that the V-shaped spring does not come off, and the connecting member shown in FIG. In order to attach these connecting members to the cover, an attaching method using parts such as screws has been performed. However, in order to fix the screws, it is necessary to install them using screw parts and tools, which is troublesome.

  As a technique that saves this effort, there is one disclosed in Patent Document 5. In the technique of Patent Document 5, the mounting method does not require parts such as screws or tools, it can be mounted with bare hands, and the suspension member is not easily detached from the connecting member. However, this connecting member has a large number of curved portions and claw portions, has a complicated shape, and is expensive.

  Further, the present applicant has developed the connecting member disclosed in Patent Document 6, but in order to set the connecting member 1 in the state shown in FIGS. Therefore, it is necessary to perform the operation after the upper part of the connecting member 1 is slightly tilted to the left in the drawing, which complicates the operation. In addition, since the mounting method uses a lot of spring property, depending on the variation in spring accuracy, it may be easier to use a tool for the work.

  In order to solve the above-described problems, the connection method of the present invention is a lighting device including an instrument body and a cover that is detachably attached to the instrument body via a suspension member. The suspension member and the cover The connecting member is composed of a substrate portion and a folded portion, the folded portion locks the suspension member, and the substrate portion is provided on the cover. The suspension member and the cover are connected to each other by sliding into the slit and fitting the opening provided in the substrate portion and the fitting protrusion provided in the cover.

  The connecting member is formed of an elastic material. Although not particularly limited, it is preferable to use metal or plastic. The folded portion is formed so that the material can be bent or bent and folded to lock the suspension member.

  The suspension member refers to a product obtained by processing a wire material represented by a V-shaped spring. However, a suspension member deformed from a V-shaped spring as shown in Patent Document 1 or 2, It may be a rhombus or a heart-shaped spring, and any shape can be used as long as it has the same purpose.

  Further, in the connection method of the present invention, when the connection is performed, the suspension member is disposed in the direction in which the folded portion is closed by disposing the tip portion of the folded portion in the direction of closing the folded portion from the block member provided on the cover. It is characterized by preventing it from coming off. The block member has a simple configuration when the above-described fitting protrusion has its role.

  In the connecting method of the present invention, the connecting member can be easily attached to the cover with bare hands without using parts such as screws, so no tools are required and labor is required. Thereby, connection of a suspension member and a cover is performed in a short time. Moreover, since it is a simple structure, it can be provided at low cost.

It is an expansion perspective view of the part which has connected the cover and the V-shaped spring using the conventional connection member. It is a perspective view which shows the lighting fixture using the connection member by the connection method of this invention. It is a perspective view which shows the connection member by the connection method of this invention. It is sectional drawing of the connection member in the AA line of FIG. It is an expansion perspective view of the part to which the connection member of the cover by the connection method of this invention is attached. It is the perspective view which showed the state which connected the cover and the V-shaped spring with the connection method of this invention.

  Hereinafter, an embodiment of the present invention will be described with reference to FIGS.

  FIG. 2 is a view showing a lighting fixture using a connecting member according to the connecting method of the present invention. An engagement member 41 is provided inside the side plate of the instrument body 4 that houses a lamp (not shown) so that the V-shaped spring 2 can be suspended. A connecting member 1 is attached to the cover 3. The cover 3 is connected to the V-shaped spring 2 by the connecting member 1, and when the V-shaped spring 2 is suspended from the engaging member 41, the cover 3 is pulled and attached to the instrument body 4 by the force of the spring.

  As shown in FIGS. 3 and 4, the connecting member 1 according to the connecting method of the present invention basically includes a substrate portion 11 and a folded portion 12. The material is an elastic metal plate. The folded portion 12 is formed by bending a metal plate, and is formed integrally with the planar substrate portion 11. The board part 11 has a shape in which both left and right ends swell like a wing from the base of the folded part 12. Further, the substrate 11 has an opening 13 having a width W with a distance H from the bottom.

  FIG. 5 is a view showing the slit 31 and the fitting protrusion 32 provided in the cover 3. The slits 31 are a pair of left and right structures, and are formed to serve as guides when the connecting member 1 is slid and attached to the cover 3. As shown in FIG. 6, the slit 31 also has a function of suppressing the attached connecting member 1 from moving in the front-rear direction with respect to the surface of the substrate portion 11. The fitting protrusion 32 is formed on the cover 3 with a height H1 equal to or higher than H and a width W1 equal to or lower than W. When the height H1 is closer to H, the vertical movement when the connecting member 1 is attached is reduced, and when the width W1 is closer to W, the horizontal movement is less.

  The fitting protrusion 32 is formed by obliquely chamfering the upper part. As a result, when the connecting member 1 is attached while sliding downward, the lower portion of the opening 13 of the connecting member 1 is deformed at the chamfered portion and rides on the fitting protrusion 32, and the fitting protrusion 32 is fitted into the opening 13. The connecting member 1 that has been deformed during insertion returns to its original shape due to elasticity. By returning to the original shape, the lower part of the opening 13 of the connecting member 1 is prevented from coming off the connecting member 1 that is blocked and attached to the lower part of the fitting protrusion 32. The chamfer is formed in a flat surface in this embodiment, but may be formed in a curved surface.

  When the connecting member 1 is attached to the cover 3, as shown in FIG. 6, the distal end portion 14 of the folded portion 12 is arranged in the direction in which the folded portion 12 is closed from the fitting protrusion 32 (front side in the figure). To do. The fitting protrusion 32 serves as a block member that suppresses the movement of the distal end portion 14 and prevents the V-shaped spring 2 from coming off the folded portion 12. The opening 13 is sufficiently large so that the folded portion 12 can pass through.

  The connecting member of the present invention can be used when connecting the cover of the lighting fixture and the suspension member, and can also be applied as a connecting member other than the lighting fixture.
