Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for covering an automobile wheel disc with a decorative plate,
This invention relates to a center lock device that tightens and locks this decorative plate onto a wheel disc with one cap nut.

[Prior art and its problems]

Racing cars use center wheels in which the wheel disc is connected to the axle with only one cap nut. For this center wheel, a seat plate with a thick threaded tube is fully fastened to the hub of the axle, the threaded tube is fitted into the core hole of the wheel disc, a cap nut is screwed onto this, and the wheel disc is tightened with the seat plate and cap nut. and connect it to the axle. In a normal car, the wheel disc is connected to the axle hub with 4 to 6 fastening bolts, but in contrast, a center wheel has no fastening parts in the center of the wheel disc.
It tends to be preferred in terms of design because the entire wheel disc looks neat, and is used on sports cars.

Recently, wheel discs made of aluminum (aluminum wheels) have become available. This aluminum wheel is preferred by many people because it allows you to design it in any way you want, but conventional aluminum wheels only require a few fastening bolts and a nut to connect the axle!・The central part of the aluminum wheel also does not look good because several fasteners are visible in the center of the wheel disc. Therefore, I put a decorative plate on the center part of the wheel disc with a metal plate on the aluminum wheel, and attached this decorative plate to the wheel disc with one cap nut to improve the appearance of the aluminum wheel and make it look like a center wheel. Wheels are proposed. However, since the conventional decorative plate type wheels do not have a locking mechanism on the cap and the stop, the cap nut can be easily removed, and therefore there is a problem that the wheel is easily used by removing the decorative plate metal.

An object of the present invention is to incorporate an electronic lock or a cylinder lock into a cap nut of a decorative plate type wheel of an automobile, and prevent theft of the wheel.
The object of the present invention is to provide a center lock device for automobiles that can actually prevent e-Mli.

[Means for solving problems]

The non-invention is a decorative plate type car width in which a decorative plate is covered over the center part or the entire IIJ of a wheel disk fastened to the 7th part of the axle of an automobile, which has a threaded groove on the outer circumferential surface and a toothed edge on the inner circumferential surface. Tighten the decorative plate by screwing a cap nut onto the barrel protruding from the center of the wheel disc and protruding from the core hole of the decorative plate.Insert an electronic lock or cylinder into the inner surface of the end plate of the cap nut. Attach the lock board with the entire lock installed, fit a locking plate with a claw piece that engages with the toothed edge of the barrel into the groove of the lock board, and create a recess in the center of the locking plate to create an electronic lock. Alternatively, the cam plate of the cylinder lock is fully retracted 1 In the narrow groove adjacent to this recess, the protrusion protruding from the groove bottom of the lock board and the tension spring that is received by this are fully retracted. It engages with the toothed edge of the tube metal to stop the zero valve rotation of the bag (y),
Push the locking plate all the way back with the large diameter part of the cam and add a V so that the claw piece is completely removed from the toothed edge of the barrel metal.

The locking plate 43 fits into the groove of the lock board fixed inwardly, and normally the cam 50 brings its small diameter part into contact between the trochanters, and the elasticity of the spring 48 causes the locking plate 43 to The claw piece 44 is pushed out from the locking board 34 by pushing it out, but when turning the cap nut N to the left, the claw piece ■ slides on the toothed edge 27 and releases the locking plate 43, so the cap nut N is pushed out. You can turn it to the left to confess. When the cap nut is turned approximately 180 degrees, its protruding edges 32 and 32 reach the terminal ends of the threaded grooves 24 and 25 on the sleeve metal, and the claw piece 44 on the locking plate engages either the upper or lower toothed edge 27 of the sleeve metal. Because I want to meet and prevent Fukuro Natsuto's efforts,
The cap nut N will not come loose while the car is being driven, and it will not be illegally removed to steal the wheel. In addition, the electronic lock L built into the bag nut locks the lock plate 6 when the magnet in the vertical plate enters the recess 61 in the ring.
2 is connected to the lock board 62, thereby preventing rotation of the vertical plate 62 and establishing an electronic lock state. When replacing the wheel, simply fit the main piece 70 of the key into the recess, stack it on the lock lug, and use the magnet 73 of the key to attach the magnet inside the lock plate.
・Suction everything and insert it into the recess 61 on the edge of the ring 36...
The electronic lock L is unlocked by pulling it out, and the lock plate 62 is made rotatable. Then, when the key K is turned about 180 degrees, the lock plate and its 8 pieces 67 turn, and the 8 pieces 67 is cam 50t - about 180 degrees.
Turn the cam to bring the large diameter part of the cam into contact with the trochanter. As a result, the locking plate 43 is pushed back against the cam 50 against the spring 48,
When the claw piece 44 comes off the toothed edge 27 of the barrel metal and sinks into the lock base plate, the cap nut N becomes movable at the same time. In this state, the ball 57 enters the small hole 59 of the cam, stops the movement of the cam 50, and holds the locking plate 34 in its fully pushed back state. It will be a mistake. Therefore, after attaching a wrench to the cap nut N and removing it from the sleeve metal 20, the decorative plate 16 is removed, and the fastening teeth 15 are removed, and the entire wheel is replaced.

After replacing the wheels, cover with the decorative plate 16 and screw in the cap nut N. At this time, leave the electronic lock Lf in the unlocked state and turn the cap nut until it is fully screwed in by hand, then place the key K on the lock plate 62 and return it approximately 180 degrees. As a result, the electronic lock L is locked and the large diameter portion of the cam 50 is separated from the trochanter O, so that the claw piece seal of the locking plate engages with the toothed edge 27 of the barrel metal. Therefore, put a wrench on the cap nut N, screw it in firmly, and use one cap nut to tighten the decorative plate 16t to the wheel disc 1.0 The above describes one embodiment of the present invention, and the present invention is not limited to this embodiment. For example, the present invention can be used for an ordinary steel disk, the toothed edge 27 can be provided on the entire inner circumferential surface of the barrel 20, and the electronic lock L can be replaced with the toothed edge 27. A cylinder lock may also be used.

It is also possible to cover all corners of the wheel disc with the decorative plate 16.By making the decorative plate from synthetic resin, you can create a wheel with a very good appearance while being able to design it with complete freedom. .
