[Problems to be solved by the device]

 However, in the former known device, even if the outer peripheral surface (4) of the bag nut (1) is shaped as a tapered taper surface, the engaging groove (6) depressed from the outer peripheral surface (4) is 180 Due to the fact that they are distributed at positions facing each other, they can be gripped by the use of common pliers, and there is a risk that they will be rotated.

Further, since the engaging recess (5) is exposed at the tip of the bag nut (1), dust or muddy water adheres and accumulates while the vehicle is in use, and its makeup effect is exerted. In addition to the possibility of obstruction, the inner peripheral surface of the engaging recess (5) also has a square shape that is depressed at a position facing each other by 180 degrees, so that it is also possible to insert it by using a common forked fork or the like. I have a fear of being moved.

On the other hand, in the latter known device, on the other hand, the outer peripheral surface of the bag nut (1) is shaped as a tapered taper surface (3a) (13a), but still has polygonal engaging portions (3) (13). Therefore, it may be rotated by a common wrench.

In this regard, in the embodiment shown in FIG. 3 of the above-mentioned known device, although the polygonal engaging portion (13a) is engraved in the shape of a spline shaft, the spline groove portions face each other by 180 degrees. Due to the distribution corresponding to the position, there is still room for rotation by commercially available pliers.

[0007]

[Means for Solving the Problems]

 The present invention is intended to improve such a problem, and for that purpose, it is composed of a pair of a bag nut fastened to a hub bolt of an automobile and a plug socket fitted into the bag nut, and a tip portion of the socket. For anti-theft kits for automobile wheels equipped with locking projections for rotary operation tools such as common hexagonal wrench,

The outer peripheral surface of the bag nut has a circular shape, and a plurality of key recesses are cut out on the circular outer peripheral surface in parallel with the axis of rotation and in a distributive distribution state on the diameter line that does not face each other. The present invention is characterized in that a plurality of convex strips that mesh with the concave strips are integrally projected inward from the circular inner peripheral surface of the insertion socket.

[0009]

[Action]

 According to the above configuration of the present invention, the outer peripheral surface of the bag nut is formed into a circular shape, and a plurality of concave lines that are depressed from the circular outer peripheral surface are in a scattered distribution state in which the bag nut itself does not face each other on the diameter line. Since it is arranged in the bag, it is impossible to rotate the bag nut unless the socket is used in which a plurality of protrusions that mesh with the recesses are correspondingly projected. The combined use of nuts and plug sockets ensures the prevention of theft of automobile wheels.

[0010]

【Example】

 Hereinafter, the specific configuration of the present invention will be described in detail with reference to the drawings. In FIG. 1 showing the mounting state of the automobile wheel, (11) is a plurality of hubs (12) integrally planted from an axle hub (12). The hub bolts (stud bolts) (13) are disks of the wheel (W), and a plurality of disk mounting holes (15) for receiving the hub bolts (11) are formed around the shaft hole (14) of the wheel (W). Constant P. C. The apertures are distributed on the D (Pitch Circle Diameter).

(16) is a bush press-fitted into each disk mounting hole (15) thereof, and (N) is a hub disk (13) fixedly integrated with the hub disk (12). ) Is a bag nut (hub nut) that is fastened to the), but in the present invention, in order to prevent the theft of the wheel, it is plastically processed into the following special shape. The bag nut (N) cannot be rotated unless it is used together with (S).

That is, as shown in FIGS. 2 to 5, the bag nut (N) of the present invention has a circular shape with a constant diameter (D) on the outer peripheral surface (17), especially the front end side thereof. On the circular outer peripheral surface (17) of the bag nut (N), a plurality of recesses (18) serving as keys are arranged in parallel in a cutout line along the direction of the rotation axis of the bag nut (N) itself.

In this case, a plurality of the recesses (18) are phase-shifted into a scattered distribution state in which they do not face each other on the diameter line of the bag nut (N) itself, and the cutout surface of each recess (18) is changed. Is shaped like an arc. Due to such a special structure, even if a common gripping tool such as a plier or a fork fork is used, the bag nut (N) cannot be rotationally operated and cannot be pulled out from the hub bolt (11). Of.

In this respect, in FIGS. 2 to 5, there are a total of three recessed strips (18), and they are cut out in a scattered distribution state in which the adjacent intersecting angles of 105 degrees and 150 degrees are maintained. If only a total of 3 pieces are used, the notch processing can be performed relatively easily, and various bag nuts (N) whose crossing angles change slightly as shown in Figures 6 to 8 are available in abundance without restrictions. There are advantages. However, the total number of the recessed lines (18) may be two or four or more.

Reference numeral (19) is a stopper which projects from the base end side of the circular outer peripheral surface (17) having a constant diameter (D) of the bag nut (N) and which receives the insertion socket (S). Regulate the anti-catch. However, the formation of the stopper (19) may be omitted, and the recessed line (18) may be cut out in a row over substantially the entire length of the circular outer peripheral surface (17) of the bag nut (N). Absent.

Reference numeral (20) is a conical seat surface formed at the base end of the bag nut (N), which fulfills an aligning action with the bush (16). Similarly, (21) is a convexly curved decorative surface formed at the tip of the bag nut (N), and (22) is a female screw engraved inside the bag nut (N). It goes without saying that they will be jointly concluded.

Next, as shown in FIGS. 9 to 12, the insertion socket (S) is a rotation operation tool such as a hexagonal shape protruding from the socket main body (23) and its tip end along the rotation axis direction. The socket body (23) has a diameter (d) substantially equal to the circular outer peripheral surface (17) of the bag nut (N).

Moreover, from the circular inner peripheral surface (25) of the socket body (23), a plurality of convex ridges (26) that mesh with the concave ridges (18) of the bag nut (N) project inward integrally. When the circular inner peripheral surface (25) of the socket body (23) is fitted onto the circular outer peripheral surface (17) of the bag nut (N), the convex ridges (26) and the concave ridges (18) are provided. By engaging with, the bag nut (N) can be reliably rotated.

At that time, as shown in FIGS. 10 and 12, the above-mentioned convex stripes (26) of the insertion socket (S) are retained in total to three corresponding to the concave stripes (18) of the bag nut (N), and each of them is If the projecting surface of the ridge (26) is also formed in an arc shape, the insertion socket (S) can be easily and correctly aligned with the bag nut (N), and the rotating operation can be performed quickly. is there.

A rotary operation tool (T) such as a common hexagonal wrench is locked in the crowned state on the locking projection (24) of the insertion socket (S), and the tool (T) is locked. Of course, the bag nut (N) is pivotally operated via the socket (S).

In using the present invention configured as described above, the bag nut (N) is screwed onto the hub bolt (11) which is installed from the hub (12) of the axle as shown in FIG. Then, the socket (S) is inserted into the bag nut (N), and the socket (S) is fitted in the state in which the concave line (18) and the convex line (26) are engaged with each other.

Then, a turning operation tool (T) such as a hexagon wrench is locked to the locking projection (24) of the insertion socket (S), and the tool (T) is rotated. Then, the bag nut (N) is tightened and fixed to the hub bolt (11), and then the operating tool (T) as well as the insertion socket (S) is pulled out from the bag nut (N).

Then, as suggested from FIG. 1, the hub bolt (11) is kept in the makeup state covered by the bag nut (N), and the outer peripheral surface ( 17) is formed in a circular shape, and the recesses (18) are arranged in a circular arc notch array as a distributive distribution state on the diameter line of the bag nut (N) that does not face each other. It is impossible to rotate the bag nut (N) in the direction for loosening it unless the special insertion socket (S) corresponding to the above is used.

Therefore, as suggested by the comparison of FIGS. 5 to 8, with respect to a plurality of recessed ridges (18) that are depressed from the circular outer peripheral surface (17) of the bag nut (N), their scattered distribution positions or adjacent positions. To prevent wheel theft accidents by preparing a pair of bag nuts (N) with different crossover angles and corresponding insertion sockets (S). Can be done.

[0025]

[Effect of device]

 As described above, the present invention comprises a pair of the bag nut (N) fastened to the hub bolt (11) of the automobile and the insertion socket (S) fitted into the bag nut (N). In an antitheft kit for an automobile wheel, which is provided with a locking projection (24) for a rotary operation tool such as a common hexagon wrench at the tip of S),

The outer peripheral surface (17) of the bag nut (N) has a circular shape, and a plurality of concave grooves (18) serving as keys are provided on the circular outer peripheral surface (17) in parallel with the rotation axis and on the diameter line. A plurality of convex strips (26) that mesh with the concave strips (18) while notching in a scattered distribution state that do not face each other are projected inward integrally from the circular inner peripheral surface (25) of the insertion socket (S). Therefore, it is possible to improve the problems of the prior art, and it is possible to completely prevent the theft accident of the vehicle wheel.

That is, according to the above configuration of the present invention, the outer peripheral surface (17) of the bag nut (N) is formed in a circular shape, and the recessed line (18) serving as a meshing key with the insertion socket (S) is also formed. Literally, it is depressed from the circular outer peripheral surface (17). Moreover, a plurality of the recessed strips (18) are arranged and arranged in the bag nut (N) in a scattered state in which they do not face each other on the diameter line.

[0028] Therefore, as in the publicly known device mentioned at the beginning, tools such as pliers and bifurcated forks, which are commercially available, are locked by grasping the outer peripheral surface of the bag nut (N) so that the bag is held. It is impossible to rotate the nut (N) at all, and a special insertion socket (S) is also used in which a plurality of convex ridges (26) that mesh with the concave ridges (18) are formed. As a result, the bag nut (N) can be reliably rotated for the first time.

Further, particularly when the structure of claim 2 is adopted, the concave line (18) on the bag nut (N) side and the convex line (26) on the insertion socket (S) side mesh with each other in an arcuate surface. Since the insertion socket (S) allows the bag nut (N) to be swung quickly and reliably, the tip of the gripping tool such as common pliers or forked forks is It is not possible to slide it into engagement with the arcuate groove (18) of the bag nut (N), so that the above effect can be achieved more and more completely.

Further, if the structure of claim 3 is adopted, the bag nut (N) itself can be manufactured more easily due to the interspersed distribution of the recessed ridges (18), which are limited to a total of three, and it is particularly preferable. When these bag nuts (N) are not facing each other on the diameter line of the bag nut (N), various bag nuts (N) whose interspersed distribution positions and adjacent crossing angles are different are prepared. There is an easy effect, and the same can be said for the insertion socket (S) paired with the bag nut (N 2).

Further, since a stopper (19) having a diameter larger than its straight diameter (D) is projected from the base end side of the circular outer peripheral surface (17) of the bag nut (N), The insertion socket (S) used together can be stably received, and the turning operation tool (T) has an effect that the turning operation can be performed quickly and reliably.
