It becomes orthogonal to the longitudinal direction in which 2 extends. Therefore, when the joint end face of the illumination lamp cover 2 is brought into contact with the joint face plate 6 and the joint end face of the illumination lamp cover 3 is brought into contact with the joint face plate 5, respectively, the engaging projection 9 and the engaging projection 7 hold the engaging piece 26. In this state, the top plate parts 21, 23 or the side plate parts 22, 24 of the respective lighting cover 2, 3 or the side plate parts 22, 24 are screwed to a display shelf or a display case (not shown) such as wood screws in this state. To fix each.

Next, FIG. 3 shows a corner joining device for a lighting cover according to a second embodiment of the present invention, and FIG. 4 is a detailed view of a connecting block 30 used as a connecting member in the same embodiment. Is. In this joining device, the respective illumination lamp covers 2 and 3 are arranged in a valley shape of 135 degrees as shown in FIG. 3 (a), or as shown in FIG. 3 (b), a complementary angle to that of FIG. 3 (a). It is used when joining in a state of being arranged in a mountain shape of 225 degrees forming a. The connection block 30 includes a block body 31, joint face plates 32 and 33 formed on two opposing faces of the block body 31, and two joint face plates 32 and 33 protruding in parallel from each other. It is provided with one engagement protrusion 34, 35 and engagement protrusion 36, 37. As will be described later, the connecting block 30 is used after being rotated 180 degrees on a horizontal plane to be used, and each of the two lighting lamp covers arranged in a mountain shape of a predetermined angle and a valley of a complementary angle with this. The joint face plate 32, the joint face plate 33, the engaging protrusions 34, 35, and the engaging protrusions 36, 37 are arranged on the left and right sides so that they can be commonly used for connecting the two illumination lamp covers arranged in a shape. It is formed symmetrically. The connecting block 30 is integrally formed of a synthetic resin material such as ABS resin as in the connecting block 1 described above, and the surface thereof is subjected to surface treatment such as chrome plating by vacuum deposition.

The connection block 30 will be described in more detail with reference to FIG. 4. The block body 31 has a bottom portion 38 opened to form a hollow portion 39 therein for the purpose of weight reduction and material saving. In order to reduce the thickness of the plates 40 and 41 and prevent distortion due to sink marks during molding, slit-shaped counterbore holes 44 and 45 from the top plate 43 side to the bottom 38 side of the respective square plates 40 and 41. Has been drilled. Further, arc-shaped chamfers 40a and 41a are provided on the bottom portion 38 side of the respective square plates 40 and 41 so as to match the shapes of the respective illumination lamp covers 2 and 3 and the bottom portions 38 of the respective joint face plates 32 and 33. The sides are chamfered 32a and 33a, respectively, and a square groove 46 is formed between the joint face plates 32 and 33. It should be noted that each of the illumination lamp covers 2 and 3 used here is cut at a right angle to the longitudinal direction in which the joint end faces extend as described above, and the illumination lamp covers 2 and 3 are held between them. A desired number of fluorescent lamp sockets 27 are attached to each of the pieces 25 and 26, and a fluorescent lamp 28 is inserted into the fluorescent lamp sockets 27.

When the display shelf or display case has, for example, a valley-shaped corner portion of 135 degrees, the connection block 30 has the top plate 43 side as an upper surface as shown in FIG. 4A. When the surfaces of the square plates 40 and 41 are arranged in contact with the valley-shaped corners, the joint face plates 32 and 33 are orthogonal to the directions in which the illumination lamp covers 2 and 3 are extended. Therefore, when the joint end face of the illumination lamp cover 2 is brought into contact with the joint face plate 32 and the joint end face of the illumination lamp cover 3 is brought into contact with the joint face plate 33, respectively, the engaging protrusion 35 and the engaging protrusion 37 are engaged with each other. In this state, the top plate portions 21 and 23 or the side plate portions 22 and 24 of the respective illumination lamp covers 2 and 3 are attached to a display shelf or a display case (not shown) with screw means such as wood screws. To fix each.

On the other hand, when the display shelf or display case is provided with, for example, a mountain-shaped corner portion of 225 degrees, the connection block 30 is changed from the state shown in FIG. 3A to the state shown in FIG. When the square plates 40 and 41 are arranged so as to be in contact with the angled corners by rotating horizontally, the joint face plate 33 extends in the longitudinal direction of the illumination lamp cover 2 and the joint face plate 32 forms the illumination lamp cover 3. Are orthogonal to the extending longitudinal direction. Therefore, when the joint end surface of the illumination lamp cover 2 is brought into contact with the joint face plate 33 and the joint end surface of the illumination lamp cover 3 is brought into contact with the joint face plate 32, the engaging protrusion 36 and the engaging protrusion 34 hold the engaging protrusions 34 and 34, respectively. 26, and in this state, the top plate portions 21, 23 or the side plate portions 22, 24 of the respective illumination light covers 2, 3 are attached to a display shelf or a display case (not shown) by using screw means such as wood screws. Fix each.

[Effect of the device]

 As is apparent from the above-described embodiments, in the corner joining device of the lighting lamp cover according to the present invention, the joining end surface of each lighting lamp cover is extended by using the connecting member set at a desired arrangement angle. Since it is used in a state of being cut at right angles to the longitudinal direction, it can be cut accurately and can be easily connected at a desired angle, and the length of the joint end face is slightly shorter when cutting. Unlike the conventional technology, even if there is an error in the angle or the angle is generated, the desired mounting is possible and the material of the lamp cover is not wasted. Also, by using this connecting member in a state of being rotated by 180 degrees on a horizontal plane, the connection between the two lighting lamp covers arranged in a mountain shape with a predetermined angle and the supplementary angle It is extremely convenient because it can be used to connect two illumination lamp covers that are arranged in a valley shape.
