Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge collar which is used by being attached to a mounting portion of an attached body and which is engaged with a hinge pin supported by a mating member of the attached body to form a hinge mechanism. .

[0002]

2. Description of the Related Art Conventionally, for example, in a hatchback vehicle, FIG.
As shown in 0, a package tray trim 2 that interlocks with a back door 1 is mounted, and the front end of the package tray trim is generally supported by a receiving portion of a vehicle interior member via a hinge mechanism so as to be detachably and rotatably supported. Target. In the figure, 3 is a suspender that connects the back door 1 and the rear end of the package tray trim 2.

FIG. 11 shows an example of the above hinge mechanism.
In the same figure as seen from the back side of the package tray trim 2, a metal reinforcement hose 4 and a hinge pin support portion 5 are integrally formed on the back surface side of the package tray trim 2 made of synthetic resin. The protruding hinge pin 5a projects from the side cutout portion 6 of the package tray trim 2, and the hinge pin 5a is engaged with the hinge collar member 7 attached to the vehicle interior member to form a hinge mechanism. Has become.

[0004]

However, since the above-mentioned package tray trim 2 is a thin plate and is a relatively large component, for example, a metal rein hose 4 is required to provide the hinge pin 5a. In order to eliminate the reinforcement hose 4 and reduce the weight, it is necessary to change the hinge pin support portion 5 into a form in which it is assembled with screws or the like.
This time, the man-hour will increase.

By the way, it is possible to provide a hinge collar on the package tray trim 2 and a hinge pin on the vehicle interior member. In that case, if the hinge collar is directly formed in the plate-shaped portion on the side of the package tray trim 2, it is difficult to make that portion suitable for sliding, and it is difficult to integrally form small parts. It is not a good idea in terms of formability and repairability. In addition, although a skin is usually attached to the package tray trim 2, it is necessary to add man-hours to improve the end treatment of the skin near the hinge collar.

Therefore, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a hinge collar which is separate from an attached body (package tray trim) and which can be easily and quickly attached and detached. To aim.

That is, the invention of claim 1 is a hinge collar for use by being attached to an attaching portion of an attached body and engaging with a hinge pin supported by a mating member of the attached body to form a hinge mechanism. A first member and a second member, which face each other and can sandwich the mounting portion, are integrally molded into a connected state via a bendable connecting portion, and the first member and the second member An engaging protrusion that is inserted into a penetrating portion formed in the mounting portion is provided on one of the two, and a receiving portion that is engageable with the engaging protrusion is provided on the other, and the first protrusion is provided. Member and second
At least one of the members is provided with a collar portion that is rotatably engageable with the hinge pin. To attach the hinge collar to the mounted body, the first member and the second member are bent at the connecting portion, the mounting portion of the mounted body is sandwiched, and the engaging protrusion is inserted into the penetrating portion of the mounting portion. The part is inserted and then engaged with the receiving part. Therefore, the hinge collar can be attached in a one-touch type, which improves workability. Further, the hinge collar can be formed of a synthetic resin of an appropriate material, which contributes to weight reduction of the hinge mechanism on the mounted body side. Further, the hinge collar can cover the end of the mounting portion to improve the appearance.

According to a second aspect of the present invention, in the hinge collar according to the first aspect, the collar portion includes the first member and the second member.
The member is formed so as to project between the first member and the second member when the mounting portion of the mounted body is sandwiched, and the peripheral side portion of the collar portion is the mounting portion of the mounting portion. It is characterized in that it can be brought into contact with the end portion. The hinge collar is in a mounted state in which the outer peripheral side portion of the collar portion is in contact with and supported by the end portion of the mounting portion of the mounted body,

According to a third aspect of the present invention, in the hinge collar according to the second aspect, the collar portion has a holding portion formed in a substantially C-shaped cross-section to which the hinge pin can be attached and detached, and a C portion thereof.
It is characterized by comprising a locking piece which is provided in the opening of the character and is formed so as to be elastically displaceable, and a bent guide path which is connected to the opening and regulates the attaching / detaching direction of the hinge pin. Therefore, the hinge pin and the holding portion can be engaged / disengaged by relatively moving the hinge collar and the hinge pin in a predetermined direction to elastically displace the locking piece. It should be noted that the hinge pin once engages with the guide path when separated from the holding portion. That is, the attached body to which the hinge collar is attached can be easily and quickly assembled / disassembled with respect to the mating member, while the attachment / detachment direction can be regulated to prevent inadvertent disassembly due to erroneous operation or the like. .

[0010]

Next, an embodiment of the present invention will be described with reference to the drawings. 1 is a perspective view of the hinge collar, FIG. 2 is a front view of the hinge collar, and FIG. 3 is a side view of the hinge collar. As shown in FIGS. 1 to 3, the hinge collar 9
Is a pair of plate-shaped first member 10 and second member 20,
Thin and bendable connecting parts 30 at left and right
The first member 10 is a schematic structure integrally formed of synthetic resin in a connected state via (generally referred to as a thin hinge portion), and will be described in detail later, but in a bent state at the connecting portion 30. The first member and the second member 20 sandwich the plate-shaped mounting portion (also simply referred to as the mounting portion) of the mounted body (for example, the package tray trim 2 of the hatchback vehicle shown in FIG. 10). A collar portion 15 for engaging with a rod-shaped hinge pin 8 (see FIG. 7) supported on the side of a mating member (for example, an interior member of a car) of the mounted body is formed on the other side of the second body. The member 20 is formed with a cutout portion 25 having a shape corresponding to the collar portion 15. A material having sufficient strength and abrasion resistance is appropriately selected as the synthetic resin. Hereinafter, description will be made in order.

The first member 10 is provided with engaging protrusions 11 which can engage with through holes 21 (described below) of the second member 20 at two positions on the left and right sides. As shown in FIGS. 3 and 4, reference numeral 11 denotes a stepped base 12 in which a pair of elastic tongues 13 formed in a split state through slits are extended in a tapered shape. The elastic tongue 13 has a retaining claw 13a that bulges laterally in the middle part. It should be noted that the first member 10 has a hole 10a penetrating at a position along the base end of the base 12 so that the retaining claw 13a can be operated from the opposite side as necessary.

On the other hand, the second member 20 is formed with a through hole 21 as a receiving portion in the present invention, and the through hole 21 has a diameter smaller than the bulging dimension of the retaining claw 13a of the engaging projection 11. And the edge of the hole is stepped portion 12 of the base portion 12.
It can be brought into contact with a. The through hole 21
Referring to FIG. 2, in order to avoid interference with the tip of the elastic tongue 13 when inserting the engaging projection 11, the circular hole 21a having a cross-sectional shape corresponding to the base 12 is connected to the square hole 21b to widen in one direction. It has a curved shape.

Further, as shown in FIGS. 1 and 2, an abutment seat 14 is provided at the edge portion of the first member 10 on the connecting side with a stepped portion 1.
A strip-shaped connecting portion 30 that is provided to project at substantially the same height as 2a and extends from the side surface of the contact seat 14 is connected to one end of the second member 20. That is, after bending the first member 10 and the second member 20 at the connecting portion 30, the elastic tongue piece 13 is inserted into the through hole 2.
When pushed in 1, the elastic tongue 13 once contracted and deformed elastically restores as shown in FIG. 4, so that the retaining claw 13a engages with the edge of the through hole 21 to prevent the retaining. At this time, as shown in FIG. 8, the second member 20 may substantially contact the contact seat 14 and the stepped portion 12a to maintain a predetermined distance between the first member 10 and the second member 20. You can do it.

Next, the color section 15 will be described. As shown in FIGS. 1 and 2, a wall body 16 extending in the illustrated shape is provided at an edge portion of the first member 10 on the connection side so as to surround a cutout portion corresponding to the cutout portion 25 of the second member 20, The wall body 16 is formed to be higher than the abutment seat 14 by the thickness of the second member 20, and when the first member 10 and the second member 20 are bent at the connecting portion 30, the tip end of the wall body 16 is formed. The portion fits into the cutout portion 25. Furthermore, the wall 1
Locking piece 1 of the shape shown in the drawing that half-closes the opening of the notched portion surrounded by
7 protrudes from the wall body 16 in a cantilever manner, and is connected to the substantially C-shaped holding portion 18 having an inner diameter corresponding to the hinge pin 8 and the C-shaped opening by the locking piece 17 and the wall body 16.
A curved guide path 19 is formed. The exit of the guide path 19 is slightly widened so that the hinge pin 8 can be fitted easily.

Next, the hinge collar 9 is attached to the attached body,
Specifically, an example will be described in which the hinge mechanism is attached to a package tray trim of a hatchback vehicle to form a detachable hinge mechanism with a hinge pin provided on the vehicle interior member side.
FIG. 5 is a perspective view showing a main part of the package tray trim 32. As shown in the figure, plate-shaped mounting portions 33 are provided on both left and right sides of a package tray trim 32 made of resin, for example, and the wall bodies 16 of the collar portion 15 of the hinge collar 9 are fitted into the plate-shaped mounting portions 33. Notch-sized notch 34
And a through hole 35 through which the engaging protrusion 11 of the hinge collar 9 can be inserted.

Now, when attaching the hinge collar 9 to the plate-like attachment portion 33 of the package tray trim 32,
The first member 10 and the second member 20 are bent at the connecting portion 30, and the plate-like mounting portion 33 is sandwiched, the collar portion 15 is fitted into the notch 34, and the engaging projection 11 is pushed into the through hole 35. Then, referring to FIG. 4 and FIG. 8, the elastic tongue piece 13 once contracted and deformed elastically restores, so that the retaining claw 13a engages with the edge portion of the through hole 21 to prevent the retaining tab 13a from coming off, and the mounting is easily completed ( 6 and 7).
That is, since fastening parts such as bolts and rivets are not used, it can be mounted with one hand in one-touch type, and the workability is extremely good. At this time, the second member 20 substantially contacts the abutment seat 14 and the stepped portion 12a, so that the first member 10 and the second member 20 are kept at a predetermined distance, and the collar portion 15 is Notch 3 on the outer peripheral side of the wall body 16
4 and the tip of the outer peripheral side portion thereof abuts on the notch portion 25 to be supported. The plate-shaped mounting portion 33
The cut end of the notch 34 is protected by the hinge collar 9 and the design is improved.

Next, the operation of attaching and detaching the package tray trim 32, to which the hinge collar 9 has been attached, to the vehicle will be described. The hinge pin 8 is provided on the vehicle interior member side.
(See FIG. 7) is provided so as to project substantially horizontally. The above-mentioned attachment / detachment operation is performed by moving the hinge collar 9 of the package tray trim 32 with respect to the hinge pin 8 in the direction perpendicular to the axis to engage and disengage the hinge collar 8. That is, as shown in FIG. 9, the package tray trim 32 is moved with respect to the hinge pin 8 so as to guide the hinge pin 8 to the holding portion 18 along the bent guide path 19. At this time, the locking piece 17 is bent by the hinge pin 8 so that the opening is once widened, and then elastically restored to hold the hinge pin 8 in the holding portion 18.

On the other hand, when removing the package tray trim 32, the rear end of the package tray trim 32 is lifted up, and the package tray trim 32 is pulled out obliquely upward so that the hinge pin 8 moves in the guide path 19 as shown in FIG. . That is, this hinge mechanism has a structure in which the rear end of the package tray trim 32 cannot be pulled out diagonally upward unless the back door of the hatchback vehicle is opened, and the package tray trim 32 is simply lifted from the rear seat. Even if you try to do so, you cannot remove it, so it is suitable for cases where the confidentiality of the package space and crime prevention are important. Therefore, the hinge mechanism allows easy and quick assembly / disassembly of the package tray trim 32, while the removal direction thereof is restricted, so that careless disassembly due to erroneous operation or the like can be prevented.

When the hinge collar 9 is damaged, only that part can be easily replaced, so that maintainability is good.

[0020]

As described above, according to the present invention,
Since the hinge collar can be attached to the attached body in a one-touch type, workability is good, and the weight of the hinge mechanism and the designability can be improved. Further, in this hinge collar, since the outer peripheral side portion of the collar portion that engages with the hinge pin abuts against the end portion of the mounting portion and is supported, it is possible to secure support rigidity with a relatively simple configuration. Further, the attached body to which the hinge collar is attached can be easily and quickly assembled / disassembled with respect to the mating member, while the attachment / detachment direction can be restricted to prevent inadvertent disassembly due to erroneous operation or the like. .
