Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a hook structure which is attached to, for example, a panel such as an interior trim of an automobile to lock an object to be locked.
[0002]
[Prior art]
BACKGROUND ART Conventionally, a hook is attached to a panel of an interior trim of an automobile or the like in order to lock a locked object such as a handbag or a net on a panel of the trim.
[0003]
As such a hook, for example, a hook 1 described in JP-A-2002-120627 shown in FIG. 12 is conventionally known.
[0004]
The hook 1 has a washer member 1a inserted into the mounting hole 2a of the interior trim 2, and a hook member 1b for fitting a base to the top of the washer member 1a.
[0005]
When the hook 1 is attached to the interior trim 2, the fixing bolt 1c is inserted through the insertion hole 1b1, the washer member 1a, the substrate 1e, and the spacer 1f at the base of the hook member 1b, and then the tip of the fixing bolt 1c is inserted. The interior trim 2 and the body panel 3 are connected to the washer member 1a and the substrate 1e by inserting the internal trim 2 into the insertion hole (not shown) of the body panel 3 and screwing the fixing nut 1d to the tip of the fixing bolt 1c. , And is interposed between the hook member 1b and the fixing nut 1d via the spacer 1f.
[0006]
As another example of such a hook, a hook 4 described in JP-A-8-68412 as shown in FIG. 13 is known.
[0007]
The hook 4 has a female member 4a inserted into the mounting hole 2a of the interior trim 2, and a male member 4b fitted into the female member 4a.
[0008]
The female member 4a is provided with a locking shoulder 4c. The locking shoulder 4c is locked to the peripheral edge of the mounting hole 2a, so that the female member 4a can be prevented from coming out of the mounting hole 2a. I have.
[0009]
The male member 4b has a holder 4d for locking the object to be locked, and the holder 4c is rotatably supported by the male member 4b.
[0010]
When the hook 4 is attached to the interior trim 2, the male member 4b is fitted into the hollow body of the female member 4a locked to the interior trim 2.
[0011]
[Problems to be solved by the invention]
It is desirable that such a hook be easily attached from the viewpoint of reducing the number of work steps. Further, it is desirable that the weight that can be locked (load resistance) is large so that a heavier locked object can be locked.
[0012]
However, since the conventional hook 1 is attached with the fixing bolt 1c and the fixing nut 1d, a large load resistance can be obtained, but the work of screwing the fixing nut 1d to the fixing bolt 1c takes time. , Resulting in an increase in the number of work steps.
[0013]
On the other hand, in the hook 4, the hook 4 can be attached simply by fitting the male member 4b into the hollow body of the female member 4a, but the holder 4d formed in a substantially C-shape has both ends 4d1 and 4d1 of male members. Since the mounting holes 4b1 and 4b1 formed on the side of the side 4b are simply fitted, the ends 4d1 and 4d1 come off the mounting holes 4b1 and 4b1 when a relatively large load acts on the holder 4d. There was a possibility that a heavy object to be locked could not be locked to the holder d.
[0014]
Therefore, the present invention has been made in view of such a conventional problem, and a hook capable of locking a heavy object to be locked and which can be easily attached to a panel. It is intended to provide a structure.
[0015]
[Means for Solving the Problems]
In order to achieve the above object, a hook structure according to the first aspect of the present invention includes a base member, a hook member, and a lock pin, and the base member is inserted through a mounting hole of a panel. A plurality of first locking pieces locked from inside the mounting hole on the back surface of the panel and a plurality of second locking pieces protruding to the opposite side across the first locking piece and the panel, and A lock pin insertion hole is formed between the plurality of first locking pieces and between the plurality of second locking pieces.
[0016]
The hook member includes a third locking piece that is engaged with the second locking piece and is restricted from moving in the lock pin insertion hole direction.
[0017]
Further, the lock pin is inserted into the lock pin insertion hole to regulate inward bending of the first locking piece and the second locking piece.
[0018]
Moreover, the lock pin is provided concentrically with the lock pin and outside the engagement portion with the second locking piece and the third locking piece, and is provided with the second locking piece and the third locking piece. A cylindrical wall for preventing the second locking piece and the third locking piece from flexing and deforming outward and disengaging the engaging section by sandwiching the engaging section with the lock pin is provided integrally. ing.
[0019]
【The invention's effect】
In the device according to claim 1 configured as described above, the lock pin is inserted into the lock pin insertion hole to restrict inward bending of the second locking piece, and is provided integrally with the lock pin. The cylindrical wall sandwiches the engagement portion between the second locking piece and the third locking piece between the lock pin and the second locking piece and the third locking piece flex outward and deform. To prevent the engaging portion from coming off.
[0020]
For this reason, the engagement of the third locking piece engaged with the second locking piece does not come off, and the movement of the third locking piece in the direction of the lock pin insertion hole is maintained. The hook member is prevented from coming off the member.
[0021]
Furthermore, since the lock pin regulates the inward bending of the first locking piece, the locking of the first locking piece to the back surface of the panel does not come off, and the base member is separated from the panel. Removal is prevented.
[0022]
Therefore, even if a heavy object to be locked is locked to the hook member, the base member is not detached from the panel, and the hook member is not detached from the base member. It is a hook structure that can lock a locking object.
[0023]
Furthermore, since the lock pin can be attached to the panel simply by inserting the lock pin into the lock pin insertion hole, the hook structure can be easily attached to the panel.
[0024]

[0038]
Further, a flange 14e extending in a radial direction from a lower end portion of the cylindrical wall 14b is provided integrally with the cylindrical wall 14b.
[0039]
As shown in FIG. 1, the flange 14e has a substantially umbrella-shaped cross-section that is inclined downward while maintaining a substantially constant thickness.
[0040]
In addition, the peripheral edge of the flange 14e abuts on the interior trim 11 in a state of covering the base member 12.
[0041]
Thus, the appearance of the base member 12 is prevented from being impaired.
[0042]
Further, the hook member 13 has a hollow cylindrical tubular portion 13b and a hook body 13c extending outward from the upper end of the tubular portion 13b, and is formed in a substantially T-shape in side view. I have.
[0043]
As shown in FIG. 10, four (plural) notches 13 e that open downward are formed below the cylindrical portion 13 b, and four (plural) third members are provided between the notches 13 e, 13 e. A stop piece 13a is formed.
[0044]
A locking hole 13d is formed at the lower end of the third locking piece 13a, and a second guide 13a1 that is inclined downward from the inside is formed at the lower end surface.

[0047]
Moreover, the engaging portion of the locking claw 12g of the second locking piece 12b with the locking hole 13d of the third locking piece 13a is sandwiched between the lock pin and the cylindrical wall 14b.
[0048]
This restricts the second locking piece 12b from bending toward the center of the lock pin insertion hole 12c and restricts the third locking piece 13a from bending in the radial direction of the lock pin insertion hole 12c. Is restricted so that the locking claw 12g of the second locking piece 12b does not come off the locking hole 13d of the third locking piece 13a.
[0049]
Next, the operation of the hook 10 having such a hook structure will be described along the mounting method.
[0050]
First, as shown in FIGS. 3 and 4, the first locking piece 12 a of the base member 12 is inserted into the mounting hole 11 a of the interior trim 11, and the lower surface of the base member 12 is brought into contact with the interior trim 11.
[0051]
On the other hand, the third locking piece 13a of the hook member 13 is inserted between the lock pin 14a and the cylindrical wall 14b and is inserted into the insertion hole 14d.
[0052]
At this time, the third locking piece 13a is inserted until the locking hole 13d provided in the third locking piece 13a is positioned below the cylindrical wall 14b.
[0053]
Then, with the hook member 13 attached to the lock member 14 in this manner, the lock pin 14a of the lock member 14 is inserted into the lock pin insertion hole 12c of the base member 12.
[0054]
At this time, the lock pin 14a is inserted into the lock pin insertion hole 12c such that the second guide 13a1 of the third locking piece 13a contacts the first guide 12g1 of the second locking piece 12b.
[0055]
In this state, the hook member 13 and the lock member 14 are further pressed toward the base member 12.
[0056]
As a result, the first guide 12g1 and the second guide 13a1 exert outward pressure on the second locking piece 12b, thereby bending and deforming the third locking piece 13a outward.
[0057]
Further, by pressing the hook member 13 and the lock member 14 toward the base member 12, the locking holes 13d of the third locking pieces 13a are inserted into the locking claws 12g of the second locking pieces 12b so that the locking pin insertion holes 12c are formed. Engage from the radial direction.
[0058]
As described above, by engaging the locking claw 12g of the second locking piece 12b with the locking hole 13d of the third locking piece 13a, the third locking piece 13a of the hook member 13 can be inserted into the lock pin. The movement in the direction of the hole 12c is restricted, and the hook member 13 does not come off the base member 12 in the direction of the lock pin insertion hole 12c.
[0059]
Further, the lock pin 14a inserted into the lock pin insertion hole 12c is in contact with the inner surface of the second locking piece 12b, and regulates the inward bending of the second locking piece 12b.
[0060]
Next, as shown in FIGS. 1 and 2, the lock member 14 is pushed down to bring the peripheral edge of the flange 14 e into contact with the interior trim 11, and as shown in FIG. Cover 12 up.
[0061]
By covering the base member 12 with the flange 14e, the appearance quality of the hook 10 is improved.
[0062]
In addition, by pushing down the lock member 14 in this manner, the lower outer surface of the lock pin 14a comes into contact with the protrusion 12e to push the first locking piece 12a outward, thereby trimming the first locking piece 12b to the interior trim. 11 is locked from the inside of the mounting hole 11a.
[0063]
In this state, the lock pin 14a restricts the first locking piece 12b from bending inward, thereby preventing the first locking piece 12b of the base member 12 from coming out of the mounting hole 11a.
[0064]
At this time, the cylindrical wall 14b is located outside the engaging portion between the second locking piece 12b and the third locking piece 13a, that is, the engaging portion between the locking claw 12g and the locking hole 13d.
[0065]
Therefore, the engaging portion between the second locking piece 12b and the third locking piece 13a is sandwiched between the lock pin 14a and the cylindrical wall 14b.
[0066]
Accordingly, the cylindrical wall 14b prevents the second locking piece 12b and the third locking piece 13a from flexing and deforming outward and disengaging the engaging portion, and the locking claw 12g and the locking hole 13d are prevented. Is prevented from being disengaged.
[0067]
As described above, in the hook 10 of the present embodiment, the lock pin 14a restricts the inward bending of the first locking piece 12a of the base member 12 so that the first locking piece 12a moves to the rear surface of the interior trim 11. In addition to preventing the lock from being released, the lock pin 14a and the cylindrical wall 14b sandwich the engagement portion between the second locking piece 12b and the third locking piece 13a, and the second locking piece 12b It is suppressed that the engaging piece 13a bends and deforms outward to disengage the engaging portion, and prevents the engaging between the engaging claw 12g and the engaging hole 13d from being disengaged.
[0068]
For this reason, even if a heavy object to be locked is locked to the hook 10, the first locking hole 12a comes out of the mounting hole 11a and the base member 12 comes off, or the locking claw 12g and the locking hole 13d Does not come off and the hook member 13 comes off.
[0069]
Further, while the first locking piece 12a of the base member 12 is inserted through the mounting hole 11a, the third locking piece 13a of the hook member 13 is inserted into the insertion hole 14d of the lock member 14, and The hook 10 can be attached to the interior trim 11 simply by inserting the lock pin 14a of the lock member 14 into the lock pin insertion hole 12c. Therefore, the hook 10 can be easily attached to the interior trim 11 without screwing or the like. It is possible to reduce the number of mounting work steps.
[0070]
As described above, the hook structure of the hook 10 of the present embodiment includes the base member 12, the hook member 13, and the lock pin 14a, and the base member 12 is provided with an interior trim (panel). The four (plural) first locking pieces 12a and the first locking pieces 12a that are inserted into the mounting holes 11a and are locked from the inside of the mounting holes 11a to the back surface of the interior trim 11 are the interior trim 11. A lock pin insertion hole including four (plural) second locking pieces 12b protruding to the opposite side with being sandwiched, and extending between the four first locking pieces 12a and between the four second locking pieces 12b. (Lock pin arrangement space) 12c is formed.
[0071]
The hook member 13 includes a third locking piece 13a that is engaged with the second locking piece 12b and is restricted from moving in the direction of the lock pin insertion hole 12c.
[0072]
Further, the lock pin 14a is inserted into the lock pin insertion hole 12c to regulate the inward bending of the first locking piece 12a and the second locking piece 12b.
[0073]
In addition, the lock pin 14a is provided concentrically with the lock pin 14a outside the engagement portion with the second locking piece 12b and the third locking piece 13a, and is provided with the third locking piece 12b and the third locking piece 12b. A cylindrical wall that suppresses the second locking piece 12b and the third locking piece 13a from bending and deforming outward by sandwiching the engagement portion with the piece 13a with the lock pin 14a. 14b are provided integrally.
[0074]
According to this configuration, the lock pin 14a is inserted into the lock pin insertion hole 12c to restrict the inward bending of the second locking piece 12b, and the cylindrical wall 14b provided integrally with the lock pin 14a. Is interposed between the lock pin 14a and the engagement portion between the second locking piece 12b and the third locking piece 13a, and the second locking piece 12b and the third locking piece 13a flex and deform outward. The engagement portion is prevented from coming off.
[0075]
Therefore, the third locking piece 13a engaged with the second locking piece 12b from the radial direction of the lock pin insertion hole 12c is not disengaged, and the lock pin insertion hole 12c of the third locking piece 13a is not released. The restriction of the movement in the direction is maintained, and the hook member 13 is prevented from coming off the base member 12.
[0076]
Further, since the lock pin 14a restricts the inward bending of the first locking piece 12a, the locking of the first locking piece 12a to the back surface of the interior trim 11 does not come off, and the base member 12 is fixed to the interior trim. 11 is prevented from being detached.
[0077]
Therefore, in the hook structure of the hook 10, even if a heavy object to be locked is locked to the hook member 13, the base member 12 can be removed from the interior trim 11, and the hook member 13 can be removed from the base member 12. A heavy object to be locked can be locked without coming off.
[0078]
Furthermore, since the hook 10 can be attached to the interior trim 11 simply by inserting the lock pin 14a into the lock pin insertion hole 12c, the hook 10 has a hook structure that can be easily attached to the interior trim 11.
[0079]
Further, in the hook structure according to the embodiment of the present invention, a flange 14e that covers and hides the base member 12 is integrally provided on the cylindrical wall 14b.
[0080]
According to this configuration, since the flange 14e covers the base member 12, the appearance quality is good.
[0081]
The embodiment of the present invention has been described above with reference to the drawings. However, the specific configuration is not limited to this embodiment, and any change in design within the scope of the present invention is included in the present invention.
[0082]
For example, the locking hole 13d of the third locking piece 13a can be engaged with the locking claw 12g of the second locking piece 12b from the radial direction of the lock pin insertion hole 12c. The locking piece 13a may be engaged from the center.
[0083]
In addition, if the movement of the second locking piece 12b and the third locking piece 13a in the direction of the lock pin insertion hole 12c is restricted, the engagement between the second locking piece 12b and the third locking piece 13a is restricted. In this case, it is not always necessary to use the locking claws 12g and the locking holes 13d.
[0084]
For example, a locking claw that can engage with each other may be provided on the second locking piece 12b and the third locking piece 13a.
[0085]
Further, the protruding portion 12e is formed at the inner lower end of the first locking piece 12a, but may be formed at the outer lower end of the first locking piece 12a.
[0086]
Also in this case, the lock pin 14a restricts the inward bending of the first locking piece 12a, so that the locking of the first locking piece 12a to the back surface of the interior trim 11 is prevented.
[0087]
The lock pin 14a is in contact with the inner surface of the second locking piece 12b to regulate the inward bending of the second locking piece 12b. It does not necessarily have to be in contact with the side surface.
[0088]
That is, as long as the inward bending of the second locking pieces 12b can be regulated, the second locking pieces 12b may have an appropriate interval.
[0089]
Although the cylindrical wall 14b is cylindrical, it can restrict the second locking piece 12b and the third locking piece 13a from bending and deforming outward at the engaging portions of each other. If so, it may be polygonal cylindrical.
