Description

[Detailed Description of the Invention] This invention relates to an improvement of the hinge structure in a rear parcel for an automobile.

A luggage compartment formed between a rear seat and a tailgate of a batchback type passenger car is covered by a rear parcel so that it can be opened/closed and removed.

In addition, if the luggage compartment is large, the rear parcel can be divided into two parts, front and rear, so that it can be opened and closed from either the rear seat side or the tailgate side.

In the case of this two-part type, hinge members are provided on both sides of the joining edges of the front and rear panels that make up the rear parcel, and the rear parcel is installed across the entire width of the passenger compartment. Therefore, the hinge member is necessarily located at the bottom of each panel.

However, in this arrangement, since the panel hits the head of the hinge member, the rotation angle of the panel is restricted, and it is not possible to open the panel at a rotation angle of 1800 degrees.

In order to solve this problem, it is also possible to provide a notch in the edge of the panel so that it can be opened and closed at all angles.

However, in this case, the hinge member will be exposed on the upper surface of the rear parcel, resulting in an unsightly appearance.

To overcome this inconvenience, it has been considered to completely cover each panel by gluing the carpet onto the panels.

However, with this structure, when the panel is folded, the carpet is also folded together, making it difficult to operate, and furthermore, the carpet easily peels off from the folded portion, resulting in poor durability.

This invention was devised in view of the above-mentioned drawbacks of the conventional art, and its purpose is to enable the panel to be opened and closed at all angles without providing a notch in the panel.

Hereinafter, one embodiment of this invention will be explained in detail with reference to the drawings. Figure 1 shows a rear parcel for an automobile to which this invention is applied.
and a rear panel 2 on the back door side, and hinge members 3 according to this invention are provided on the lower surfaces of both sides of the joining edge portions IA and 2A between the two.

As shown in FIG. 2, this hinge member 3 includes a hinge block having a pair of protrusions 4, 4 vertically protruding from both ends and formed into a concave shape overall, and each protrusion on this hinge block 5. 4, and a support shaft 7, which is coaxial with one hinge shaft 6 and protrudes from the opposite side thereof, is provided on the other side of one of the protrusions. .

Furthermore, claw portions 6A are formed at the tip ends of each of the hinge shafts 6, and are provided toward the outside of each other.

Each of these hinge shafts 6 is formed at the lower part of the front panel 1 and the rear panel 2, and is configured to be pivotally attached to a rail that also serves as reinforcement.

That is, a hinge receiver made of a reinforcing pipe 8 such as a metal cylinder is provided on the lower surface of the joining edge of the front panel 1 by embedding a member, and a rectangular reinforcing rail 9 is provided at the lower part of the joining edge of the rear panel 1. The hinge receiver is provided by embedding the members or the like.

Therefore, one hinge shaft 6 can be fitted directly to the pipe 8, and the other hinge shaft can be fitted to the reinforcing rail 9 via the joining block 10, and In the fitted state, the claw portion 6 on the -blade side
A protrudes into a notch 8A formed in the pipe 8 and is prevented from coming out, and a claw 6A of the hinge shaft 6 on the other side protrudes from the outer periphery of the block 10. , it is designed to prevent its removal.

As shown in FIG. 3, the support shaft 7 is connected to the inner cavity 11 of a υ-shaped bracket 11 that is provided to protrude from the inside of the vehicle body.
a, and is rotatably supported within the inner cavity 11a of the bracket 11.

Therefore, the hinge member 3 itself is rotatably supported within the vehicle, and each hinge shaft 6 protruding from the hinge member 3 is rotatably supported inside the vehicle.
, 6, both panels 1 and 2 are rotatably supported.

Further, the top of the convex strip 4 on the front panel 1 side of the hinge member 3 is formed into an arcuate surface 4a with the axial center of the hinge shaft 6 as the center point.
During the rotation operation, the lower edge surface of the front panel 1 is rotated while slidingly contacting the circular arc surface 4a.

On the other hand, the top of the protruding strip 4 on the rear panel 2 side is formed as a flat surface 4b as a whole, and its inner surface is formed as an arcuate surface 4a' in the same manner as above, so that the rear panel 2 Relative rotation toward the rear lower side with respect to the protruding strip 4 is restricted.

Furthermore, one side of the concave inner bottom surface 5a of the hinge block 5, that is, the 1 facing the 90° rotation position of the rear panel 2.
A locking step portion 5b which is one step higher than the locking step portion 5b is formed protrudingly on the surface, and the rear panel 2 comes into contact with the end surface thereof when the rear panel 2 is rotated by 90 degrees.

Therefore, when the front panel 1 on the rear seat side is rotated to open the luggage compartment at the bottom when the front panel 1 is installed in this manner, first, as shown in Fig. The panel 1 rotates around the hinge shaft 6 of the hinge member 3, and its lower surface slides along the outer periphery of the ridge, and then comes into contact with the inner surface of the ridge, standing upright at approximately 90 degrees. Rotation is once regulated.

If the front panel 1 is rotated further than this rotation angle, the hinge member 3 itself will now rotate around the support shaft 6 while maintaining the state of contact with the front panel 1, and as a result, the fifth As shown in the figure, the entire front panel 1 can be folded.

In addition, during such an operation, it is extremely important that the top of the protruding strip 4 on the rear panel 2 side be flat 4b in order to be able to perform this type of operation smoothly.

That is, the figure shown in FIG. 6 shows a hinge structure using the hinge member 3' that is the basis of the present invention, and the top of the protruding strip 4' on the rear panel 2 side is the same as that on the front panel 1 side. It has an arcuate shape.

In this way, when the rear panel 2 side is also made into an arcuate surface, when the front panel 1 is rotated as shown in FIG.
As shown in the figure, the hinge member 3' rotates downward around the support shaft 7' due to the weight of the front panel 1, so the front panel 1 rotates at a rotation angle of 90 degrees as shown by the imaginary line in the figure.
The panel is rotated once in a lowered position up to 100 degrees, and then folded up 1800 degrees as shown in FIG.

On the other hand, in the hinge member according to the present invention, the protruding portion 4 that comes into contact with the rear panel 2 is flat as a whole 4b.
Therefore, relative rotation between the rear panel 2 and the protruding strip 4 in such a state is prevented, and this prevents unnecessary movement when the front panel 1 is rotated 90 degrees. be.

・Also, the rear panel 2 side can only be expanded to 90 degrees,
When rotated by 90°, the end portion 2A is connected to the locking step portion 5b.
is confronted by.

Considering the case where the locking step portion 5b is not formed at this time, FIG. 7a.

As shown in b, the hinge member 3' tends to swing when the panels 1 and 2 are upright, and therefore the panels 1 and 2 move up and down relative to each other in the up and down direction, making them unstable.

On the other hand, if the locking stepped portion 5b is formed as described above, the end portion 2A will abut against this as shown in FIG. 7C, and the hinge member 3 will be fixed relative to the panel 2. It becomes a stable state.

The hinge structure according to the present invention is configured as described above, but according to the present invention, the following special effects can be obtained.

(a) The hinge member in the present invention is as described above,
A pair of vertical protrusions are formed on both ends to form a concave shape, and a hinge shaft is provided protruding from the protrusions, and the hinge shaft is provided on the lower surface of both panels. Since it is constructed so that it can be supported easily, there is no need to provide a notch in both panels for attaching a hinge member like in the past, and even if both panels are placed close to each other, they can be rotated sufficiently. It is.

Therefore, the hinge member in the present invention is completely hidden behind the bottom surfaces of both panels, making it impossible to see the hinge member from the outside.Also, there is no notch in both panels, and both panels are placed close together. As a result, it has excellent flatness and continuity, and the appearance is improved.

(b) In the present invention, for example, when the front panel is lifted and rotated, the panel rotates around the hinge axis, and the lower surface of the panel slides along the outer circumference of the convex part of the hinge member, and then the inner It is configured so that its rotation is once restricted when it comes into contact with the side surface and stands upright at approximately 90' as shown in FIG.

In other words, since the panel is configured to rotate intermittently, the panel is not rotated or folded all at once on the rear panel, so it will not accidentally hit the luggage on the rear panel, and the luggage Damage can be prevented and 180°
It is convenient to use because it is foldable.

In addition, in the present invention, even when the rear panel is rotated, it goes without saying that the rotation is restricted to approximately 90 degrees.

(C) According to the hinge structure according to the present invention, there is no need for a cutout for attaching the hinge member, so there is no need to cover the panel with a carpet or the like.

Therefore, the folding of the panel is easy to operate, and there is no risk of the carpet or the like coming off in the folded portion, so it is highly durable.

(d) Furthermore, since the hinge member according to this invention is flattened with the top of the convex strip on the protruding side of the support shaft, when one panel is completely folded, the hinge member at an intermediate position is There is no unstable behavior, and since the end of the panel abuts against the locking step at the 90° rotation position, there is no swinging of the hinge member at the 90° folding position, resulting in stability during rotation operation. This has the advantage of providing improved operability.
