[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a shelf panel made of a press-formed metal plate, which is an improvement of the connection structure of the corner portion between the front wall and the side wall, which are formed by bending the upper wall downward.

[0002]

[Prior art]

 The press-molded shelf panel is formed into a thin box shape in which the front and rear walls and the left and right side walls are respectively formed downward from the front and rear edges and the left and right side edges of a generally flat upper wall, and are opened downward. At this time, the front and rear walls and the left and right side walls are often connected at a corner portion. For example, as shown in FIG. 6A, a connecting piece 31 is bent and formed on one of the front walls 30, and the connecting piece 31 is provided along the inner surface of the adjacent side wall 32, and the connecting piece 31 and the side wall 32 are spot-welded, or It is fixed with rivets. Alternatively, as shown in FIG. 6B, one front wall 30 is formed as an independent component having a U-shaped cross section, which is welded to the upper wall 34 of the shelf panel 33, and the connecting piece 31 is further attached to the side wall. It may be spot-welded to No. 32 (both documents are unknown).

[0003]

[Problems to be solved by the device]

 As described above, in the conventional shelf panel, since the corner portions of the adjacent peripheral side walls are integrated by the connecting piece, the rigidity of the corner portion is increased and the strength of the shelf panel can be increased. However, as seen in, for example, Japanese Utility Model Publication No. 57-15717, the upper end of the front wall is connected to the upper wall via a curved portion, and the joint between the front wall and the upper wall is less likely to be rounded and dropped. Absent. This is because the user easily touches the upper edge of the front wall, but in order to ease the pain in that case and to adjust the appearance. When the upper edge of the front wall is rounded off in this way, the cut edge of the metal plate is exposed at the edge of the front wall that intersects the side wall, and it is easy to get injured at the corner, and it is also necessary to cover up this cut edge. It is not easy, and the appearance is likely to be bad.

Therefore, an object of the present invention is to provide a shelf in which even if the upper edge of the front wall is formed to be round and curved, the corner portion of the front wall and the side wall where the front wall intersects with the cut edge is neatly concealed, and is firmly reinforced. To get the panel.

[0005]

[Means for Solving the Problems]

 In the present invention, as shown in the figure, the upper wall 5 to the front wall 6 and the side wall 7 intersecting with the front wall 6 are respectively bent downward, and the upper end of the front wall 6 is continuous with the upper wall 5 via a curved portion 9. The shelf panel made of a metal plate has a plastic connector 10 for connecting the front wall 6 and the side wall 7 which are adjacent to each other at their corners, and the connector 10 is attached to the inner surface of the main surface wall 12. A dowel pin 13 and a tubular wall 14 located on the front wall 6 side of the engaging pin 13 are provided in a protruding manner, and the tubular wall 14 is fitted to the side wall 7 at a corner portion with the front wall 6. An opening 15 for inserting and an engaging hole 17 into which the engaging pin 13 is fitted are respectively formed, and the main surface wall 13 covers the opening 15 when the cylindrical wall 14 is fitted inside the opening 15. , The engaging pin 13 is fitted into the engaging hole 17, and the inner side from the lower end of the cylindrical wall 14 and the front wall 6 A reinforcing wall 8 formed folded can is formed in stop-like spots in recess-projection engaging means 19 provided on each of the bonding surfaces, characterized in that is.

[0006]

[Action]

 Since the upper end of the front wall 6 of the shelf panel 3 is connected to the upper wall 5 via the curved portion 9, the front end shape of the side wall 7 at the cut end at the side end of the front wall 6 is the cut end shape at the side end of the front wall 6. Is difficult to form. Therefore, together with the opening 15 provided at the front end portion of the side wall 7, the front wall 6 is projected forward and hangs down like an elephant's nose. However, when the cylindrical wall 14 of the connector 10 is fitted into the opening 15 from the lateral outside, the principal surface wall 12 covers the opening 15. When the cylindrical wall 14 is completely fitted into the opening 15, the concave-convex engaging means 19 prevents the connecting tool 10 from slipping out and is in a fittingly killed state, and the connecting tool 10 simultaneously integrates the front wall 6 and the side wall 7. The front wall 6 and the side wall 7 are prevented from expanding outward and deforming.

[0007]

[Effect of device]

 Therefore, according to the present invention, even if the upper end of the front wall 6 of the shelf panel 3 has a rounded corner, the corners of the front wall 6 and the side wall 7 intersecting with the front wall 6 are formed by the connecting tool 10. The front wall 6 and the side wall 7 are firmly connected to each other, which contributes to the improvement of rigidity including the corresponding corner portion.

【Example】

 1 to 5 show an embodiment of a shelf panel according to the present invention. In FIG. 2, reference numeral 1 is an assembling storage. Inside this, the shelf panel 3 of the present invention is supported by brackets 4 using studs 2. The shelf panel 3 has a flat top surface and laterally long upper and lower walls 5, and front and rear walls 6 are bent downward from the front and rear edges of the upper wall 5, and left and right side walls 7 are bent downward from the left and right edges. . Further, reinforcing walls 8 having an L-shaped cross section are bent inward at the lower ends of the peripheral walls 6 and 7, respectively. As shown in FIG. 4, the reinforcing wall 8 has a horizontal bottom wall 8a bent at right angles from the lower ends of the walls 6 and 7, and a standing wall 8b bent upward from the inner end of the bottom wall 8a. . The upper end portions of the front and rear walls 6 and the front and rear end portions of the upper wall 5 are continuous with each other via a curved portion 9. The curved portion 9 is provided in order to improve the appearance by providing a rounded outer shape and to reduce pain even when the user accidentally touches the upper end of the front wall 6. is there.

The corners of the front wall 6 and the rear wall 6 that linearly intersect with each other and the left and right side walls 7 are connected by a connecting tool 10 mainly for the purpose of improving rigidity. 1 and 3 show a corner portion of a front wall 6 and a left side wall 7, and a connecting member 10 thereof has a main surface wall 12 having a vertical outer surface and a flat lower surface, and an inner surface of the main surface wall 12 which is lower than a rear side thereof. The engaging pin 13 projecting from the main surface wall 12 and the cylindrical wall 14 projecting from the inner surface of the main surface wall 12 are integrally formed by plastic molding, and the engaging pin 13 is located behind the cylindrical wall 14. The other corner portions are substantially the same, and the description thereof will be omitted.

The upper corner of the front end of the principal surface wall 12 is curved and formed in the same shape as the curved portion 9 of the front wall 6. The tubular wall 14 is formed in a rectangular tubular shape along the inner surfaces of the upper wall 5, the front wall 6 and the bottom wall 8a of the reinforcing wall 8. A notch 23 is provided in the rear left corner of the bottom wall portion of the cylindrical wall 14.

In FIG. 1, an opening 15 into which the cylindrical wall 14 of the connector 10 is fitted is cut out at the front end of the side wall 7 of the shelf panel 3, and the front end of the side wall 7 facing the opening 15 is cut out. The concave wall portion 16 is formed in a stepped shape so as to be recessed inward, and the concave wall portion 16 is provided with an engaging hole 17 penetrating therethrough. Further, the standing wall 8b of the reinforcing wall 8 of the front wall 6 is cut off at the left end portion facing the opening 15 to secure the fitting margin of the cylindrical wall 14.

The connecting tool 10 is guided from the left outer side, the engaging pin 13 is fitted into the engaging hole 17, and the tubular wall 14 is fitted into the opening 15 to be assembled to the shelf panel 3. In this assembled state, the outer surface of the main surface wall 12 is flush with the side wall 7. Therefore, the opening edge of the opening 15 is set inward from the outer wall surface of the side wall 7 by the thickness of the main surface wall 12, and the protruding portion 12a on the rear side of the main surface wall 12 is the concave wall portion of the side wall 7. 16 is joined flush with the outside.

In FIGS. 3 to 5, in order to prevent the connector 10 mounted on the shelf panel 3 from coming off and fixing it, concave-convex engaging means is provided on each joint surface of the cylindrical wall 14 and the reinforcing wall 8 of the front wall 6. 19 are provided. As the concavo-convex engaging means 19, a locking claw 20 is cut and raised downward on the bottom wall portion of the cylindrical wall 14, and a locking hole 21 is formed through the bottom wall 8a of the reinforcing wall 8 on the front wall 6 side. Set up. When the cylindrical wall 14 is completely fitted into the opening 15, the locking claw 20 is elastically deformed and falls into the locking hole 21 to engage with it, as shown in FIG. Further, the concave-convex engaging means 19 shown in the figure has locking claws 22 that are cut and raised rearward on the rear wall of the cylindrical wall 14 as well, and is shown in FIG. 3 when the cylindrical wall 14 is fitted into the opening 15. As described above, the locking claws 22 are elastically deformed and wrap around the inside of the concave wall portion 16 of the side wall 7 to be engaged therewith.

In the state where the connector 10 is assembled to the shelf panel 3, the front wall 6 and the side wall 7 which are adjacent to each other are connected via the connector 10, and each of the walls 6 and 7 tries to expand outward. To prevent. That is, as shown in FIG. 4, the force to spread the front wall 6 forward is such that the standing wall 8 b of the reinforcing wall 8 of the front wall 6 contacts the bottom wall portion of the tubular wall 14 of the connector 10 through the notch 23. When it hits, it is transmitted to the connecting tool 10, but the rear end of the connecting tool 10 is connected to the side wall 7 by the engagement of the engaging pin 13 and the engaging hole 17, so the front wall 6 including the lower end. Does not deform in the front-back direction.

On the contrary, the outward force acting on the side wall 7 is transmitted to the connecting tool 10 through the overhanging portion 12a of the main surface wall 12 circumscribing the concave wall portion 16, but is locked to the locking claw 20. Since the front end of the connector 10 is connected to the front wall 6 by the engagement with the hole 21, the side wall 7 including the lower end is not deformed in the left-right direction. Therefore, the connecting tool 10 firmly connects the front wall 6 and the side wall 7 which are adjacent to each other, and the rigidity of these corner portions becomes sufficient. By incorporating the connector 10, the respective cuts of the front wall 6 and the side wall 7 facing the opening 15 can be covered with the main surface wall 12 in a good appearance.

In the above embodiment, the notch 23 is provided in the bottom wall portion of the cylindrical wall 14 so that the forward deformation force of the front wall 6 is received by the notch 23, but this is not always necessary. This is because, for example, the front-rear spacing of the cylinder wall 14 can be matched with the front-rear spacing of the front wall 6 and the standing wall 8b, and the deformation force can be received by the cylinder wall 14. Under the same meaning, a groove into which the end of the standing wall 8b enters may be formed in the bottom wall portion of the cylindrical wall 14. The tubular wall 14 does not necessarily have to be continuous in a quadrangle, and a part thereof may be divided, or a tubular wall having three sides may be used. When the connector 10 is attached to the shelf panel 3, the main surface wall 12 may protrude from the outer surface of the side wall 7 by the thickness thereof. The curved portion 9 may be formed only on the front wall 6 of the shelf panel 3. The concavo-convex engaging means 19 do not necessarily have to be provided at two places as in the illustrated example. It suffices that the joint surface between the cylindrical wall 14 and the reinforcing wall 8 of the front wall 6 is sufficient, and the concrete concavo-convex engagement form does not matter. The concavo-convex engaging means 19 may be provided between the cylindrical wall 14 and the standing wall 8b of the reinforcing wall 8 of the front wall 6.

The peripheral edge of the main surface wall 12 may be made to project from above the upper wall 5 and from the front of the front wall 6, and a cover wall that is circumscribed to the upper wall 5 and the front wall 6 may be provided at this protruding portion. The shelf panel 3 may be formed in a polygonal shape other than a quadrangle. In any case, the front-rear and left-right positional relationship in the present invention, that is, the front wall 6 and the side wall 7 are for convenience of description, and it is only necessary that the both walls 6 and 7 intersect with each other, and it is also orthogonal. You don't need to be in touch.
