The present invention relates to a footrest having a structure.

[0002]

2. Description of the Related Art The most common mounting structure for a footrest of this type is disclosed in, for example, Japanese Patent Application Laid-Open No. 6-92173. FIG. 12 shows how the footrest is mounted. A plurality of stud bolts 31 are erected on a floor panel 30 of the vehicle body, and a footrest main body 32 is fixed to these stud bolts 31. An uneven surface for preventing slippage is formed on the upper surface of the footrest main body 32, and a cylindrical mounting boss 33 is provided on a portion of the rear surface of the footrest main body 32 facing the stud bolt 31. A step portion 33b is formed substantially at the center of the through hole 33a of the boss 33, and the inner surface below the step portion 33b has a large diameter. Through hole 3 of mounting boss 33
3a, the footrest main body 32 is attached to the stud bolt 31.
A clip 34 for fixing to the base is fitted.

A pair of footrest locking claws 34a, which can be elastically deformed with a phase difference of 180 °, project obliquely upward outward from a substantially central portion of the clip 34 in the axial direction. The pawl 34a engages with the step 33b of the mounting boss 33 to integrally connect the footrest main body 32 and the clip 34. The clip 34 is formed as a cylindrical portion 34c via a cross-shaped fitting portion 34b on the lower surface side of the head portion 34a.
An elastic locking claw 34d that meshes with the thread groove of the stud bolt 31 is provided at a part of 4c. This elastic locking claw 3
4d, when the clip 34 is fitted to the stud bolt 31, the point of the elastic locking claw 34d is
While engaging with the thread groove of the stud bolt 3, the clip 34 is bent and deformed outward to allow its entry, and at the same time, the clip 34
Prevent escape from 2.

When removing the footrest body 32,
When the clip 34 is forcibly rotated in the direction in which the stud bolt 31 comes off, the clip 3 is inserted into the through hole 33a of the mounting boss 33.
The footrest main body 32 can be pulled out from the stud bolt 31 in a state where the four are assembled.

[0005]

However, according to the footrest mounting structure disclosed in the above publication, when the footrest is removed, the clip is rotated several times to engage with the thread groove of the stud bolt. It is necessary to move the pawl along the spiral groove to the upper unlocked position.
In addition, this operation must be performed while sequentially rotating a plurality of clips attached to the footrest by substantially equal angles and adjusting the amount of movement of each clip. If the amount of movement is different for each clip, the footrest body will tilt, making it impossible to rotate the remaining clip smoothly, making it extremely difficult to remove the footrest.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and an object of the present invention is to provide a footrest which can be attached and detached by a simple operation and which does not come off unless it is intentionally operated once attached. It is in.

[0007] The object of the present invention is to provide a footrest body having a plurality of hollow mounting bosses protruding from the back surface constituting a main part of the present invention, a holding panel having a clip insertion hole which is mounted so as to protrude from a floor panel, and a holding panel having the same. and a clip is inserted into the panel and the attachment boss, the clip and a said mounting boss and locking resilient locking portion on the back surface and the clip rotation preventing pawl of the holding panel retention panel after insertion The mounting boss has a vertical groove that , when the footrest body is pressed against the mounting portion of the floor panel, abuts the holding panel and fits the rotation preventing claw ,
The clip insertion hole of the holding panel
When removing from the mounting part of the floor panel,
By rotating the lip, the elastic locking portion and the
The present invention is achieved by a vehicle footrest having a cutout portion capable of releasing engagement with a rear surface of a holding panel . When the footrest mounting portion of the floor panel is not easily elastically deformed, an elastic material is attached to the peripheral edge of the footrest body.

[0008]

The footrest body is strongly pressed against the surface of the elastic sheet while the clip is pushed in with the direction of, for example, the parallel rib formed on the upper surface thereof being parallel to the parallel rib formed on the surface of the footrest body. During this pressing, the clip is inserted into the insertion hole of the holding panel, but the elastic locking portion is restricted by the narrow portion of the insertion hole and passes while elastically deforming inward. When the elastic locking portion passes through the portion, the elastic locking portion returns to the original shape, and the elastic locking portion is engaged with the peripheral edge on the back side of the insertion hole and fixed to the holding panel.

When the footrest body is mounted,
A rotation preventing claw of the clip is fitted into a pair of vertical grooves formed in a part of the mounting boss from the beginning, and free rotation of the clip with respect to the mounting boss is prevented. Therefore, even if vibration occurs during driving of the vehicle or the like, the clip cannot rotate freely due to the engagement between the rotation preventing claw and the vertical groove, and prevents the clip from easily detaching from the holding panel.

When the footrest body attached to the floor panel in this manner is detached from the floor panel, the clip is rotated by 90 ° by an appropriate means. A transition is made from a narrow portion to a wide portion, and the clip is easily pulled out of the insertion hole by passing through the wide portion while the elastic locking portion remains in its original shape. At this time, the rotation preventing claw is elastically deformed and detaches from the vertical groove of the mounting boss, and elastically presses the inner wall surface of the hollow portion of the mounting boss, so that the mounting boss holds the clip. It does not fall out of the mounting boss.

Reference numeral 5 denotes an elastic sheet such as a carpet laid on the floor panel 4. In addition, the height of the mounting boss 2 is set to a dimension that comes into contact with the surface of the holding panel 3 when the footrest main body 1 is pressed against the elastic sheet 5.

Reference numeral 6 denotes a clip which is a feature of the present invention. The clip 6 is formed on the upper surface of the head as shown in FIGS.
a pair of elastic locking portions 6b engaging with the holding panel 3 are provided at the lower end of the clip body 1 with a phase difference of 180 °. It protrudes outward from the peripheral surface.

The inside of the mounting boss 2 is a stepped hollow portion 2a, and the clip 6 has a stepped shape that fits into the stepped hollow portion 2a. The stepped hollow portion 2a of the mounting boss 2
A pair of vertical grooves 2b are formed opposite to each other, and a pair of elastically deformable anti-rotation pawls 6c which are engaged with the vertical grooves 2b are provided at corresponding stepped positions of one clip 6 so as to protrude. At the time of locking, the free rotation of the clip 6 is prevented, but forced rotation is possible.

The pair of anti-rotation pawls 6c are point-symmetric with respect to the axis of the clip 6, and have an elastic piece 6c 'and an elastic piece 6c extending substantially along the peripheral surface of the clip 6 as shown in FIG. And a claw portion 6c '' protruding radially from the tip of the The vertical groove 2b is formed on a plane including the pair of elastic locking portions 6b. The distance connecting the locking ends of the pair of elastic locking portions 6b is set to be larger than the inner diameter of the lower end portion of the mounting boss 2;
When the clip 6 is fitted into the stepped hollow portion 2a of the mounting boss 2, the clip 6 is locked on the lower end surface of the mounting boss 2 and cannot be easily removed.

As shown in FIG. 3, the holding panel 3 has an insertion hole 3a through which the lower end of the clip 6 can be inserted. In the embodiment shown in FIG. 3, this insertion hole 3a
Is composed of a circular portion 3b occupying most of the outer periphery of the clip 6 and a cutout portion 3c through which a pair of the elastic locking portions 6b projecting outward from the lower end of the clip 6 can be inserted. The diameter of the circular portion 3b is equal to the inner diameter of the stepped hollow portion 2a of the mounting boss 2.

Next, the operation of attaching and detaching the footrest body 1 will be described. In order to attach the footrest body 1 to the floor panel 4 of the vehicle body, first, the clip body 6 is oriented so that the parallel rib 6a formed on the upper surface thereof is parallel to the parallel rib 1a formed on the surface of the footrest body 1. While pressing together, the footrest body 1
Is strongly pressed against the surface of the elastic sheet 5. During this pressing, the clip 6 is inserted into the insertion hole 3a of the holding panel 3, but the elastic locking portion 6b is restricted by the circular portion 3b of the insertion hole 3a and passes while elastically deforming inward. . When the elastic locking portion 6b passes through the circular portion 3b, the elastic locking portion 6b returns to its original shape as shown by a broken line in the upper part of FIG.
The elastic locking portion 6b is engaged with the back side peripheral edge of the circular portion 3b of the insertion hole 3a, and is fixed to the holding panel 3.

When the footrest body 1 is mounted, the pair of vertical grooves 2b formed at the stepped positions of the mounting boss 2 are fitted with rotation preventing claws 6c projecting from corresponding positions of the clip 6 from the beginning. 5, the free rotation of the clip 6 with respect to the mounting boss 2 is prevented. Therefore, even if vibration occurs during driving of the vehicle or the like, the clip 6 cannot rotate freely due to the engagement between the rotation preventing claw 6c and the vertical groove 2b, so that the clip 6 comes off the holding panel 3. Block.

When the footrest body 1 attached to the floor panel 4 is detached from the floor panel 4, a coin or the like is inserted into the groove between the parallel ribs 6a formed on the upper surface of the clip 6, and the clip 6 to 90 °
It can be easily removed by turning it. That is,
When the clip 6 in the above-described mounted state is rotated by 90 °, the elastic locking portion 6b of the clip 6 moves the insertion hole 3a of the holding panel 3 from the circular portion 3b to the cutout portion 3c as shown by a broken line in FIG. Then, the clip 6 passes through the cutout portion 3c while the elastic locking portion 6b is open, so that the clip 6 can easily come out of the insertion hole 3a. At this time, the rotation preventing claw 6c is elastically deformed and detaches from the vertical groove 2b of the mounting boss 2, and elastically presses the inner wall surface of the stepped hollow portion 2a of the mounting boss 2 as shown in FIG. As a result, the clip 6 does not fall out of the mounting boss 2 unnecessarily.

FIGS. 8 and 9 show a modification of the elastic locking portion 6b of the clip 6. FIG. FIG. 8A is a perspective view showing the entirety of the clip 16, and FIG. 8B is a view when the elastic locking portion 16 b of the clip 16 is engaged with the insertion hole 3 a of the holding panel 3. It is a state diagram. In the example shown in FIG. 8, a slit parallel to the lower end of the cylindrical clip is formed to form an elastic tongue 16b ', and a locking hook projecting radially from the tip of the elastic tongue 16b'. Part 16
b '' is formed. Of course, the pair of locking hooks 16
The dimension connecting the protruding ends of b ″ is larger than the diameter of the insertion hole 3 a of the holding panel 3. Therefore, when the lower end portion of the clip 6 passes through the insertion hole 3a of the holding panel 3, the locking hook 16b ", which has been elastically reduced in diameter, returns to its original shape, and the locking hook 16" is connected to the insertion hole 3a. It is locked to the peripheral edge of the back surface of the circular portion 3b of 3a.

FIG. 9 (a) is a perspective view showing the entire clip 26, and FIG. 9 (b) shows an elastic locking portion 26b of the clip 26 engaged with the insertion hole 3a of the holding panel 3. It is a state diagram at the time. In the example shown in FIG. 9, a pair of small diameter portions 26c whose outer diameters are reduced with a phase difference of 180 ° are formed at the lower end of the cylindrical clip, and each small diameter portion 2c is formed.
An elastic locking piece 26d extending substantially in the circumferential direction from the circumferential end of 6c protrudes. And the same elastic locking piece 26d
A locking claw portion 26d 'protruding in the radial direction is protrudingly provided at a tip end of the lock member. Of course, the dimension connecting the protruding ends of the pair of locking claws 26d 'is larger than the diameter of the insertion hole 3a of the holding panel 3. Accordingly, when the lower end of the clip 6 passes through the insertion hole 3a of the holding panel 3, the elastic locking piece 26d, which has been elastically reduced in diameter, returns to its original shape, and the locking claw 26d 'is circularly formed in the insertion hole 3a. The portion 3b is locked to the peripheral edge of the back surface.

FIG. 10 shows various modified examples of the insertion hole 3a of the holding panel 3. The shape of the insertion hole 3a is an ellipse, a rhombus, and two opposite sides are equal to each other as shown in FIG. A longer hexagon, an octagon whose opposing four sides are longer than other equal four sides, etc. can be adopted, but the shape of the insertion hole 3a can be further deformed. In short, the elastic locking portion 6b is deformed. It is only necessary that the holes have a hole shape in which a portion that can pass through the hole and a portion that cannot pass unless the locking portion 6b elastically deforms coexist.

FIG. 11 shows that the elastic sheet 5 such as a carpet laid on the mounting portion of the footrest body 1 of the vehicle body is rigid.
9 shows a modified example of the footrest main body 1 when elastic deformation is small. That is, in this modified example, the elastic member 7 such as polyurethane is attached to the peripheral portion of the footrest main body 1. When the elastic member 7 does not exist, for example, in the embodiment shown in FIG. 1, even if the footrest main body 1 is pressed against the elastic sheet 5, the clip 6 is engaged with the holding panel 3 because the deformation of the sheet 5 is small. If the clip 6 is to be engaged with the holding panel 3 in this case, it is necessary to make a play between the clip 6 and the holding panel 3, and if this play is made, the firm attachment of the footrest is required. Becomes impossible.

[0024]

As is apparent from the above description, according to the footrest of the present invention, not only is the work of attaching the footrest body to the vehicle body simple, but also the work of removing the footrest is simply by rotating the clip by 90 °. Operation can be easily performed, eliminating the need for stud bolts fixed to the floor panel as in the past, and simultaneously removing multiple clips when removing the footrest from the vehicle body by synchronizing in the direction of removal. The footrest does not need to be rotated, and once the footrest is attached, the footrest does not come off unintentionally unless intentionally removed.
