Description

[Detailed description of the invention] The present invention is a mailbox board with a decorative board, more specifically a synthetic resin decorative board that is reinforced with a reinforcing board attached to the back and holds a nameplate etc. between it and the mailbox body. This relates to a mailbox having a.

Conventionally, in mailboxes having this type of decorative board 2 that holds a nameplate plate 15 etc. between it and a mailbox main body 3 as shown in FIG. 1, in order to securely hold the nameplate plate etc. In many cases, rigid metal members such as aluminum die-casting were used.

However, such metal members are expensive, so in order to reduce the cost, metal reinforcement such as steel angle material is installed on the back side of the decorative board 22 molded with synthetic resin, as shown in FIG. There are those in which the plate 21 is fixed with screws 23 or the like so that there is no play, and there are those in which a metal reinforcing plate is insert molded.

In this conventional example, the expansion and contraction of the decorative laminate cannot correspond to the expansion and contraction of the reinforcing plate because the thermal expansion coefficients of metal and synthetic resin are different, so the decorative laminate may be deformed into a corrugated shape, or in severe cases. This had the disadvantage that the decorative board was cracked, making it aesthetically undesirable.

The purpose of the present invention is to eliminate the above-mentioned drawbacks and provide a mailbox having a decorative board that has sufficient rigidity to hold a name plate, etc., does not deform, and is inexpensive. There is something to be said.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings. The mailbox having a decorative board according to the present invention has a decorative board 2 of synthetic resin type with a metal reinforcing plate 1 fixed to the back side of the mailbox. It is attached to the front surface of the receiving box main body 3, and a boss 4 is provided on the back side of the decorative board 2 protruding approximately at the longitudinal center of the decorative board 2, and the decorative board 2 passes through the boss 4.
Left and right projections 5 are arranged on the back surface of the decorative board 2 at positions corresponding to both ends of the straight line along the longitudinal direction, and ribs 7 extend in the longitudinal direction on the rear end surfaces 6 of the left and right projections 5. The reinforcing plate 1 is fixed to the back surface of the decorative board 2 with a fixing screw 10 that is screwed into a boss hole 9 formed in the boss 4 through an insertion hole 8 provided in the center, and the reinforcing plate 1 is fixed to the back surface of the decorative board 2 in the longitudinal direction. The rib 7 protrudes into the elongated hole 11 provided at both ends and is elongated in the longitudinal direction of the reinforcing plate 1, and the screw head 14 of the screw 13 screwed into the left and right projections 12 comes into contact with the rib 7, and the screw head 14 of the screw 13 screws into the left and right protrusions 12. The peripheral edge of the elongated hole 11 is held between the head 14 and the rear end surface 6 of the left and right projections 5 so as to be movable along the longitudinal direction.
In this embodiment, as shown in FIGS. 1 to 5,
A name plate 15 and an interface 16 are held between the mailbox main body 3 and the decorative board 2.

The reinforcing plate 1 is made of a metal angle material bent into an oval shape, and grooves 18 are provided alternately around the entire circumference of the back surface of a frame-shaped decorative plate 2 having an opening 17 for a nameplate plate. Upper and lower grooves 18.
Insert the reinforcing plates 1 and 1 into the grooves 18, respectively, and screw the fixing screw 10 into the boss hole 9 of the boss 4 protruding from the longitudinal center of the groove 18 through the insertion hole 8 provided at the center of the reinforcing plate 1. A reinforcing plate 1 is fixed to a decorative board 2.

In addition, the protrusion height of the rib 7 is made larger than the thickness of the reinforcing plate 1 to hold the reinforcing plate 1 between the screw head and the rear end surface 6 of the left and right projections 5, so that the peripheral edge of the elongated hole 11 can move freely in the left and right direction. It becomes.

As described above, in the present invention, a metal reinforcing plate is fixed to the back side of a synthetic resin decorative board, so the cost can be reduced, and the decorative board supported by the reinforcing board has sufficient rigidity.
It can securely hold nameplates, etc., the reinforcing plate is fixed to the decorative board at one fixing point, the ribs protrude into the long holes on both the left and right ends of the reinforcing plate, and the screws are screwed into the left and right protruding holes through the long holes. The screw head of the screw was brought into contact with the rib, and the periphery of the elongated hole in the reinforcing plate was held between the rear end surfaces of the left and right protrusions and the screw head so that it could move left and right. This has the advantage that the difference in expansion and contraction between the reinforcing plate and the decorative plate due to the difference in expansion coefficients of the plates can be absorbed by the movement of the periphery of the elongated hole, and the decorative plate will not warp or deform into a wave shape.

In addition, the reinforcing plate can be fixed to the decorative board by screwing a fixing screw into the boss hole of the decorative board from the insertion hole in the center of the reinforcing board, and there is no wobbling between the reinforcing board and the decorative board. Moreover, the loose fit between the elongated holes of the reinforcing plate and the left and right protrusions of the decorative board can absorb the difference in expansion and contraction due to the difference in thermal expansion coefficient between metal and synthetic resin as described above.
