Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a double hinge mechanism for reinforcing a product in which opposing members are hingedly connected so that they can be opened and closed.

Conventional technology and its problems For example, when performing internal wiring in a car, a wire protector a as shown in Figure 5 is used to prevent vibration of the wires while driving, friction with the car body, and generation of abnormal noise. There is.

This electric wire protector a is made of synthetic resin, and one end of the plate-shaped support members c and c' that support the split tubes b and b' are connected with a hinge d so as to be openable and closable, and the other end is connected with a locking claw e. It is designed to be locked by a locking protrusion f that engages with this.

However, the hinge d that connects and holds the support members c and c' is generally formed thin, and especially when the hinge width g is narrow as shown in FIG. As a countermeasure to this problem, thick reinforcing parts _d1 were provided on both sides of the hinge d as shown in Fig. 7, but although it became somewhat resistant to torsion, it still broke easily. It was hot.

The purpose of the present invention is to solve the above-mentioned problems and provide a double hinge mechanism that has high hinge strength and does not easily break during operation.

Means for Solving the Problems In order to achieve the above object, in the present invention, there is a A relief edge 7 is provided, and an auxiliary hinge 8 of a size necessary for closing the members 2, 2' is provided outside the relief edge 7, and the auxiliary hinge 8 is connected to the opposing members 2, 2'.
When the member 2,
A configuration was adopted in which it is substantially flush with the outer edge of 2'.

Operation The opposing members 2, 2' can be opened using the hinge 4 as a fulcrum due to the relief edge 7, and when opened, the auxiliary hinge 8 bulges outward.

When the opposing members 2, 2' are closed using the hinge 4 as a fulcrum, the auxiliary hinge 8 is stretched straight and does not bulge out beyond the outer edges of the members 2, 2'.

Embodiment Hereinafter, an example in which the present invention is applied to a wire protector will be explained based on the drawings.

In FIG. 1, A is a wire protector, which is composed of split tubes 1, 1' for holding a plurality of electric wires, and plate-shaped support members 2, 2' for supporting the split tubes 1, 1'. One end of the opposing edges 3 of the two are connected by a hinge 4, and the other end is provided with a lock pawl 5 and a locking protrusion 6 that engages with the lock pawl 5.

The above configuration is the same as that shown in FIG.
That is, relief edges 7, 7 necessary for opening the members 2, 2' are provided on the outside of the hinge 4, and an auxiliary hinge 8 is stretched between the relief edges 7, 7.

The opening angle θ of the relief edges 7, 7 is the same as that of the supporting members 2, 2'.
It is only necessary to open the support members 2 and 2' as shown in the figure.
There are cases in which one is provided, and there are cases in which one is omitted. It is sufficient for the auxiliary hinge 8 to have a size that allows the support members 2 and 2' to be closed together, but as will be described later, when the support members 2 and 2' are closed, the auxiliary hinge 8 may be under tension with the pin. so that it is flush with the outer edges of members 2, 2'.

As shown in FIG.
Open and close freely using the fulcrum. During this opening/closing operation, the support members 2 and 2' are reinforced by the two hinges 4 and 8, so it goes without saying that they are difficult to break. Since the movement is restricted by the hinge 8, excessive twisting is suppressed and it becomes more difficult to break. Furthermore, when closing the support members 2, 2',
Even if the members 2, 2' are displaced as indicated by the arrows in FIG. 3, no unreasonable force is applied to the hinge 4 due to the tensile force of the auxiliary hinge 8. Therefore, the strength of the hinge 4 is further strengthened by the strength of the auxiliary hinge 8 and the interaction between the two.

Note that the protection of a large number of electric wires W is provided by the support members 2,
When the electric wire W is applied to one of the split tubes 1, 1' while the split tube 2' is open and the other is closed, the locking pawl 5 and the locking protrusion 6 are engaged and locked, which can be easily achieved.

FIG. 4 shows an example in which one of the opposing members is a split tube 2A and the other is a plate-shaped lid 2A'.

In this case, thick reinforcing ribs 9,
10 is attached. A relief edge 7 is formed on one of the reinforcing ribs 9, 9 and the opposite edge of the lid 2A', and the relief edge 7 is connected with a plurality of intermittent hinges 4 on the inside and an auxiliary hinge 8 on the outside. do. In addition, on the other side of the opposing edges of the split tube 2A and the lid 2A',
Similarly, a plurality of lock pawls 5 and locking holes 11 are provided.

In this way, the opposing members to be connected by the double hinge are plate-shaped bodies, as shown in FIGS. 1 and 4.
It can be applied not only to split tubes but also to a wide range of containers such as fuse boxes and their covers.The hinges 4 and auxiliary hinges 8 can also be used in various ways, from narrow to long, or continuous. Alternatively, various mounting methods are possible intermittently.

Effects of the invention As described above, the invention has two opposing members 2,
A clearance edge 7 necessary for opening the members 2, 2' is provided on the outside of the hinge 4 that connects the parts 2' in an openable and closable manner. An auxiliary hinge 8 is stretched, and when the opposing members 2, 2' are closed, the auxiliary hinge is tensioned in a straight line and becomes substantially flush with the outer edges of the members 2, 2'. Therefore, as the strength of the hinge joint increases, the resistance to twisting etc. increases, making it difficult to cut. In particular, in the present invention, when the opposing members are closed, the auxiliary hinge is attached to the outer edge of the opposing members. Since it does not protrude further, external force is less likely to be applied directly to the auxiliary hinge, and damage to the auxiliary hinge due to external force can be prevented.
