Description

[Detailed Description of the Invention] This invention relates to a luggage hinge that transmits the biasing force of a torsion bar to a luggage panel of an automobile.

FIG. 1 is an explanatory diagram showing a conventional luggage hinge. A pair of left and right supports 2 are fixed to both sides in the vehicle width direction on the back side of the back panel 1, and left and right arms 4 are rotatably connected to the middle part of each support 2 via pins 3. There is. A luggage panel 6 is attached to the tips of the left and right arms 4 via reinforcing members 5. Furthermore, an engaging claw portion 7 is formed at the front end portion of each support 2.
Both ends of the torsion bar 8 are locked to the left and right supports 2 via engagement claws 7. Further, a link 10 is connected to the intermediate portion of each arm 4 via a pin 9.
One end side is rotatably connected, and the other end side of the link 10 is engaged with the torsion bar 8,
The torsional biasing force of the torsion bar 8 is transmitted to the arm 4 via the link 10 to apply an opening force to the luggage panel 6.

Here, the link 10 has a pin coupling hole 11 and a torsion bar engaging slit 12 on a single surface as shown in FIG. 2, and the arm 4 has a U-shaped cross section as shown in FIG. 10 is connected to one side of the arm 4 by a pin 9. Therefore, in the luggage hinge in which the link 10 is connected to the arm 4 in a cantilevered manner,
When the link 10 is operated, it may play, causing the link 10 itself to be deformed, or the torsion bar 8 may
There is a danger that it will fall off.

FIG. 4 is an explanatory diagram showing another conventional link 15 proposed in place of the link 10 described above.
The link 15 has a pin coupling hole 16 and a torsion bar engagement slit 17 formed in each of the two link pieces 15A and 15B, which are welded together at a joint 18, and a pin 9 is formed as shown in FIG.
It can be rotatably connected to both sides of the arm 4 via A. However, in such a luggage hinge in which the link 15 is connected to the arm 4 in a double-sided manner, the link 15 has a large number of component parts, and a welding process is required. There is a problem in that it is difficult to ensure high welding accuracy such that the holes 16 are arranged on the same axis, and it is difficult to smoothly operate the link 15 connected to the arm 4.

This invention was devised in view of the above-mentioned conventional problems, and aims to provide a luggage hinge with a small number of component parts, high assembly accuracy, and good operability.

In order to achieve the above object, this invention connects an arm provided in the luggage panel of an automobile to the body so as to be rotatable, and a torsion bar is provided between the link rotatably connected to the middle part of the arm and the body. In the luggage hinge, the link includes a pair of pin joints on both sides that support both sides of the arm via pins, a torsion bar engaging part that extends from the pin joint on one side and engages with the torsion bar, and a torsion bar engaging part on both sides. A connecting portion that connects the pin connecting portions, and a flange portion formed at each end of the pin connecting portion and the torsion bar engaging portion are formed from a single sheet metal.

Hereinafter, embodiments of this invention will be described with reference to the drawings.

FIG. 6 is an explanatory diagram showing a link 20 applied to an embodiment of the luggage hinge according to the invention. That is, the link 20 is integrally formed from a single sheet metal, and includes a pair of pin joint parts 22 on both sides each having a pin joint hole 21 arranged on the same axis, and a pin joint part 22 on one side. A torsion bar engaging portion 24 having a torsion bar engaging slit 23, a connecting portion 25 connecting the pin connecting portions 22 on both sides, and the ends of the pin connecting portion 22 and the torsion bar engaging portion 24 are each bent so as to be reinforced. The flange portions 22A, 2
It consists of 4A.

That is, in the luggage hinge to which the link 20 is applied, the seventh arm 4 is rotatably connected to the body and has a U-shaped cross section and is provided with a luggage panel, as in FIG. As shown in the figure, the link 20 is rotatably connected via the pin 9A with the pair of pin coupling parts 22 on both sides arranged, and the link is connected to the intermediate part of the torsion bar that is locked on the body side. 2
0 torsion bar engaging slit 23 is engaged.

That is, according to the luggage hinge according to the above embodiment, the torsional biasing force of the torsion bar is transmitted to the arm 4 in a double-sided manner through the pair of pin joints 22 on both sides of the link 20, and the arm 4 is connected to the body. It rotates around the arm, allowing the luggage panel attached to the arm to be opened. That is, in such a luggage hinge, the arm 4 and the link 20 are connected in a double-sided manner,
Since the link 20 is integrally formed from a single sheet metal, the pin coupling holes 21 on both sides can be reliably and easily set on the same axis, and the rotation of the link 20 relative to the arm 4 is smooth, resulting in good operability. . Furthermore, since the link 20 is constructed from a single component, the number of manufacturing steps and weight can be reduced.

As described above, according to the luggage hinge of this invention, a pair of pin joints are arranged on both sides of the arm, which is rotatably connected to the body and has a U-shaped cross section and is provided with a luggage panel. The links are rotatably connected via pins, and the torsion bar engagement slits of the links are engaged with the middle part of the torsion bar that is locked on the body side, so the torsion biasing force of the torsion bars is applied to the links. It is transmitted to the arm in a double-sided manner through a pair of pin joints on both sides, and the arm rotates around the connection to the body, making it possible to open the luggage panel attached to the arm. In other words, in the luggage hinge of the present invention, the arm and link are connected in a double-sided manner, and since the link is integrally formed from a single sheet metal, it is easy to ensure that the pin connection holes on both sides are on the same axis. The link is set to rotate smoothly with respect to the arm, resulting in good operability. Furthermore, the number of component parts is small, and it is also possible to improve assembly accuracy.
