[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a center cap locking device for an automobile wheel (hereinafter simply referred to as a center lock) [ffl], and in particular, to a center cap locking device for an automobile wheel. , and moreover, it concerns a security reader interlock.

[Conventional technology? problems]

BACKGROUND OF THE INVENTION Some types of automobile wheels are equipped with wheel nuts, so-called center caps, for decorative purposes, as shown in FIG. 1, for example. In other words, in Fig. 1, the symbol l indicates a wheel, and this wheel l
A tire is placed low on the #11 portion of the outer periphery of the tire. The above wheel l is attached to the flange of the axle 2.
ct and is connected to the axle 2 by wheel nuts 4,4. On the outside of the wheel l, there is a cup-shaped aero fan 5 with a flange that hides the wheel nut 4'Y.
A cylindrical spinner 6 with a male thread formed on the outer circumferential surface,
For example, it is coaxially fitted with transportation 2 using a screw, and the upper i!
On the outer periphery of the d spinner 6, there is a cup-shaped center key ryf7 with 7 flanges formed with a female thread on the circumferential surface.
IHI will be given. 2. The spinner 6&1L is shown as a separate member from the wheel l in Fig. 1, but this spinner 6'Ja is also formed integrally with the wheel 1, and has 7 lunges of ty, z, and center character f7. There is also a model with a large root that hides the diameter T wheel nut 4°4, and the aero fan 5 is omitted instead.

Therefore, conventional center threads are usually provided with a screw hole that penetrates perpendicularly to the axis of the single shaft 2, and are locked to the spinner 6 by a set screw screwed into this screw hole. Therefore, there is a risk that the set screw may loosen due to photography while the moving vehicle is running, and the center cap may also loosen or fall off from the spinner 6.
There is this inconvenience.

Furthermore, if the center gap is removed by loosening it with a screwdriver or the like, the wheel nuts 4, 4 will come out, so there is also the inconvenience that the wheels are vulnerable to theft.

[Object of the Invention] Therefore, an object of the present invention is to provide a center lock that can reliably lock the center camp to the spinner and has high security.

-1, on the outside of the dial @80 rotating plates 11 and 12,
A latch body L9 is movably guided in the radial direction of the rotating plate.

As shown in FIG.
The overall shape of the formed member is a 1qI mouth shape, and the inner end (
In Figure 5, the lower end) has become thinner due to the removal of meat from both sides.
Furthermore, a twill portion having a chevron-shaped cross section is formed at the outer end.

As shown in FIG. 4, the latch body 19 is stored in a latch storage side 9b that is connected to a rectangular dial toy storage cavity 9a formed in the support block 9 through a gap, It is movably guided in the radial direction of the rotating plate.

In addition, the spring storage hole 19a of the latch body 19 (FIG. 5)
A launch spring 21 as a compression coil spring is elastically loaded inside, and the latch body 19 is urged outward by the elasticity of this launch spring 210.

Furthermore, in order to prevent the latch body 19 from falling off from the latch storage side 9b, a locking protrusion 19b (FIG. 5) is integrally provided on the inner end surface of the latch body 19 to prevent this locking. The projection 19b is slidably engaged with a guide slit opened in the support block 9 (see FIG. 3).

When the latch body 19 is in the free state shown in FIG. 3:M and FIG. S, and the third
As shown in the figure, it extends so as to straddle the i@IN of the dial hood and the second rotating plates 11 and 12. Further, the inner edge of the latch body 19 is connected to the first and second rotary plates 11.
, 12 with a slight gap between them.

IL10,000, on the circumferential surface of the spinner 6, there is formed a locking hole having a V-shaped cross section and engaging with the outer edge of the latch body 19, which extends along the generatrix thereof. The angular position of this engaging groove B is set so that it is substantially aligned with the latch body 19 when the center cat F7 is completely screwed onto the spinner 6. Three locking grooves z are formed in the S shown in Fig. 4, but this is done in consideration of the angular error at the start of threading of the spinner 6 and the center thread f7, which are separate parts. , when both are completely screwed together, either lock rs
zs can be aligned with the latch body 19, and forming a plurality of locking lines is not an essential component of the present invention. In addition, the dimension of the latch body 19 in the radial direction of the rotating plate is as shown in FIGS. , the outer end of the latch body 19 is locked f! # It is desirable to set it so that it can completely engage the feathers.

[Effect]

The center lock according to the unconventional embodiment configured as described above has a dial *8'! when the center cap 7 is attached. - Operate the 1st and 2nd
The notches 17 and 17 of the rotating plates 11 and 12 are connected to the latch body 19.
Screw it onto the spinner 6 with the angle aligned.

- When the center shaft 7 starts to turn, the outer end of the latch body 19 will eventually come to engage the spinner 6, and the latch body 19 will be pushed inward by these engagements, but at this time, the latch body 19 will be pushed inward. Since the inner end of the latch body 190 can fit into the notch 17 of the rotary plate, the outer end of the latch body can fit into the spinner 6.
The locking groove Z snaps periodically while slidingly contacting the inner surface of the
#r′? ) The screwing of the spinner 6 and the center cap 7 progresses, and when both are completely bent, the tip of the latch body 19 falls into the locking groove EK and engages with it. And the dial lock operation knob l/l'
If the center cap 70 is turned excessively and placed in an angular position that does not align with the notch χ latch body 19 of the rotating plate, the locking operation of the center cap 70 is completed.

When the center cap 7 is in the locked state 2, when an attempt is made to rotate the center cap 7, the latch body 19 is wedged due to the mutual movement of the tip of the latch body 19 and the slope of the locking groove. 19 is pushed inward against the elasticity of the latch spring, but the latch body 1 immediately
Since the inner edge of the center cap 9 comes into contact with the outer circumferential edge of the rotating plates 13 and 12 and is locked thereto, the center cap 7 becomes unable to rotate from then on, and the center cap 7 can not only be removed but also loosened. is prevented.

Center lock f71: When using J412, operate the dial lock 8 to open the rotary plate notches 17 and 1. ``K'' Align it with the latch body 19, and perform the operation opposite to that of attaching the center cap described above.

〔effect〕

As is clear from the above explanation, non-invention is when locking,
The outer end of the latch body is engaged in the engagement groove formed on the circumferential surface of the spinner, and the movement of the latch body is restrained by the outer circumferential edge of the rotary plate of the dial lock, so that the center cap This effectively prevents mutual rotation of the spinner, and thus completely prevents the center cap from loosening.

In addition, unless the dial is operated by the lock's unique combination number, the notch in the rotary plate and the latch body cannot be aligned, and therefore the center cage cannot be rotated, which prevents crime. It has various effects such as being able to function as a device.
