Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention includes a pair of tongue pieces facing each other formed by punching and bending a material plate, and the inner surface of these tongue pieces and the material plate. The present invention relates to a bracket that fits and holds an article in a space defined by a surface and the surface.

[Prior Art] FIGS. 4 and 5 exemplify a structure of a bracket 3 of this type and a component 1 attached to the bracket 3.

The component 1 is a canister of a motorcycle, and has a wedge-shaped projection 2 formed on the bottom thereof.

The bracket 3 has a pair of legs 3b and 3b formed by bending both ends of the material plate into an L shape, and the bracket 3 is opposed to each other formed by punching and bending the central plane portion 3a of the material plate. A pair of tongue pieces 4 and 4 are provided, and the inner surface of each tongue piece 4 and 4 and the upper surface of the central plane portion 3a form a dovetail-shaped engagement space 5.

The legs of the bracket 3 are fixed to the vehicle body of the motorcycle by means of bolts or the like. Then, as shown in FIG. 5, the component 1 includes the wedge-shaped projection 2 and the engaging space 5 of the bracket 3.
It is held by the bracket 3 by being fitted in.

By the way, the tongues 4 and 4 of the bracket 3 are formed by punching and bending with a press die, and as shown in FIG. Burrs 6 on the upper surface of 3c
And 7 occur.

Since the burrs 6 and 7 project into the engagement space 5, in the bracket 3, the burrs 6 and 7 hinder the smooth fitting of the wedge-shaped projections 2 and the surfaces of the wedge-shaped projections 2 are prevented. It will hurt you. Further, since the tongues 4 and 4 and the blank plate do not come into surface contact with the wedge-shaped projections 2 due to the burrs 6 and 7, there is a drawback that the parts cannot be stably held.

The above inconvenience can be avoided by deleting the burrs 6 and 7. However, it is not a good idea to perform such a deletion treatment on each of the mass-produced brackets in consideration of labor and cost.

[Object of the Invention]

In view of such a situation, an object of the present invention is to facilitate parts,
An object of the present invention is to provide a bracket that can be mounted smoothly and without damage, and that can hold components stably.

[Structure of Invention]

The present invention includes a pair of opposed tongues formed by punching and bending a material plate, and fitting an article into an engagement space formed by the inner surface of these tongues and the surface of the material plate. In the bracket which is held by the above, the tongue pieces are provided in such a manner that the burr generated by the bending process is located outside the engagement space.

〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

1 (a), (b) and (c) show a processing procedure of the bracket 11 according to the present invention.

According to this procedure, first, the material plate A shown in FIG.
Is pressed into the shape shown in FIG.

That is, the tongue piece is formed by subjecting the material plate A to punching and bending.
12 'pairs are formed symmetrically and downwardly, that is, in a manner of projecting to the lower surface side of the material plate A, and at the same time, both ends of the material plate A are bent to form L-shaped leg portions 13, 13. Form.

Next, each of the tongue component pieces 12 'of the bracket semi-finished product B is bent in the direction opposite to the above-mentioned punch-bending process direction, and the tongue pieces 12 as shown in FIG. It is formed on the upper surface side of the plate A.

The leg portions 13 and 13 may be processed at the same time as the bending process shown in FIG.

The bracket 11 of this embodiment formed as described above
The inner surface (lower surface) of each tongue piece 12 and the upper surface of the central flat surface portion 11a constitute the dovetail-shaped engagement spaces 14, 14.

By the way, when the punching and bending process shown in FIG. 7B is performed, a burr which protrudes upward is generated on the peripheral edge of the upper surface of each tongue piece 12 ', and the burr is formed by this process. A burr that protrudes downward is generated at the lower peripheral edge of the punched hole.

However, in the bracket 11 of the embodiment formed through the bending process of FIG. 7C, each of the tongues 12 has the material plate A.
Since it is projected on the upper surface side of the, as shown in FIG.
The burr 16 of each tongue piece 12 and the burr 17 of the hole 15 are both located outside the engagement spaces 14, 14.

In the bracket 11 of this embodiment, since the inner surface of each tongue piece 12 and the upper surface of the central flat surface portion 11a are both smooth, the wedge-shaped projection 2 of the component 1 shown in FIG. 4 is fitted into the engagement spaces 14, 14. The operation can be performed easily and smoothly.

The surface of the wedge-shaped projection 2 is not damaged by the burrs 16 and 17, and the surface of the wedge-shaped projection 2 fitted in the engagement spaces 14 and 14 is the inner surface of each tongue piece 12 and the central plane portion. 11
Since it comes into surface contact with a, the portion 1 can be stably held.

The bracket 11 is fixed to the vehicle body or the like of the motorcycle via the legs 13 and 13.

FIG. 3 (b) is a bracket according to another embodiment of the present invention.
It shows 110. When processing the bracket 110, the material plate A shown in FIG. 1 (a) is subjected to punching and bending processing, and the tongue component pieces protruding downward and symmetrically as shown in FIG. 1 (a). A pair of 120 'is formed, and at the same time, both ends of the material plate are bent to form L-shaped legs 130, 130. Then, as shown in FIG.
Bend 0'in the direction opposite to the punching and bending direction,
The bracket 110 is completed by forming a pair of tongue pieces 120 having an L-shaped cross section, which face each other on the upper surface side of the material plate.

The bracket 110 includes the inner surface of each tongue piece 120 and the central flat surface portion 11.
Since the square-shaped engaging space 140 is formed by the upper surface of 0a, it is used to hold a component having a protrusion (not shown) having a square-shaped cross section. In this embodiment, the burrs (not shown) generated on the peripheral edge of each tongue piece 120 and the peripheral edge of the hole 150 are both located outside the engagement space 140, so that the same as in the previous embodiment. The effect can be obtained.

〔The invention's effect〕

According to the present invention, since the burr does not protrude into the engagement space in which the component is fitted, the mounting operation of the component can be performed easily and smoothly, and there is no risk of damaging the component. Further, since the tongue piece and the material plate come into surface contact with the component fitted in the engagement space, the component can be stably held.
