Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a connecting part for attaching another member such as a lattice or decorative molding to a base member such as a lattice door or a door.

[Conventional technology]

As shown in Japanese Utility Model Application Publication No. 54-107151, a lattice is attached to a lattice door using U-shaped connecting parts,
As shown in Japanese Utility Model Application Publication No. 59-142391, a connecting part is fixed to the surface plate of the door, and a decorative molding is fitted onto the connecting part.

[The problem that the idea aims to solve]

By using such connecting parts, it is possible to attach a lattice door or a molding in a snap-type manner, but on the other hand, since these connecting parts are made of resin, the strength of the connecting parts themselves is weak, and the strength of the connection is weakened. Since the shape is complex, it is manufactured by injecting molten resin using a mold, which requires very expensive molds and resin molding machines, resulting in high manufacturing costs.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to solve the above-mentioned problems and provide a connecting component that can increase the strength of the connection and reduce manufacturing costs.

[Means and actions to solve the problem]

[Means] 1. A pair of first locking pieces 11, 11 that are bent in a substantially dogleg shape continuously with both sides of the board 10, and the board 1
A pair of second locking pieces 12, 12, which have a locking piece 16 that is diagonal with the cut-and-raised piece 15, which is formed by cutting and raising a part of the cut-and-raised piece 15, which is formed by cutting and raising both ends of 0.
A connecting part consisting of a metal plate having

2. A pair of first locking pieces 11, 11 that are bent in a substantially dogleg shape continuously from both sides of the board 10, and the board 1
A connecting part made of a metal plate having a pair of second locking pieces 12, 12, which are formed by bending a cut-and-raised piece 15 into a substantially dogleg shape.

[Effect]

A pair of first locking pieces 11, 11 are engaged with and attached to the base member, and a pair of second locking pieces 12, 12
Another member can be attached to the base member by engaging another member to the base member, and since the connecting parts are formed by bending and cutting metal plates, they are strong and can strengthen the connection strength. Since it can be manufactured, manufacturing costs can be reduced.

〔Example〕

As shown in Fig. 4, Fig. 5, and Fig. 6, the core material 1
A decorative molding 7 is attached to the front plate 2 of the door 5 by means of a connecting part 6 in a door 5 which has a front plate 2, a back plate 3 attached to the front and back sides, and a frame 4 attached around the door 5.

As shown in FIG. 1, the connecting component 6 includes first locking pieces 11, 11 on both sides of a substantially rectangular substrate 10.
It is made of a metal sheet with second locking pieces 12, 12 bent toward opposite sides at both ends.

The first locking piece 11 includes a first bent piece 13 that is continuous with both sides of the board 10 and bent at a predetermined angle, and a second bent piece 13 that is continuous with the first bent piece 13 and bent at a predetermined angle. The second locking piece 12 has a bent piece 15 formed by cutting and bending both ends of the board 10, and a cut-and-raised piece 15 formed by cutting and bending a part of the bent piece 14. It has a locking piece 16 that is oblique to the piece 15.

Then, as shown in FIGS. 2 and 3, the surface plate 2
A pair of second locking pieces 12,
12 is inserted, and the free ends of the pair of locking pieces 16, 16 are engaged with the back side of the periphery of the opening 2 of the top plate 2, and the connecting part 6 is fitted to the top plate 2 in a snap-fitting manner, and the cross section is The approximately U-shaped molding 7 is connected to the first pair of moldings 7.
The molding 7 is attached by pushing into the locking pieces 11, 11 and locking the locking protrusions 21, 21 formed on both inner surfaces of the molding 7 to the first bent piece 13.

In this way, since the connecting part 6 is made of sheet metal made by bending a metal plate, the strength of the connecting part 6 is high and the connection strength can be increased, and since it can be manufactured by bending with a press, the manufacturing cost can be reduced. can.

For example, as shown in FIG. 7a, both sides of the metal plate 17 are bent into a dogleg shape to form a pair of first locking pieces 11,
1 and 11 are cut and raised as shown in FIG. 7b to form a cut-and-raised piece 15, and a part of this cut-and-raised piece 15 is cut and raised as shown in FIG. 7c to form an engaging piece. A stopper piece 16 is formed.

Further, as shown in FIG. 8, the cut-and-raised piece 15 may be bent into a substantially dogleg shape to form the second locking piece 12. In this case, the second locking piece 12 can be formed as shown in FIGS. 9 and 10. Using the bent piece 15a on the free end side of the stopper piece 12 as a guide, push it into the opening 20 of the surface plate 2 and
What is necessary is to elastically deform the locking piece 12 and engage the bent piece 15a on the board side with the periphery of the opening 20.

[Effect of idea]

The pair of first locking pieces 11, 11 are engaged with and attached to the base member, and the pair of second locking pieces 12, 12 are attached to the base member.
Another member can be attached to the base member by engaging another member to the base member, and since the connecting parts are formed by bending and cutting metal plates, they are strong and can strengthen the connection strength. Since it can be manufactured, manufacturing costs can be reduced.
