DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in more detail with reference to the accompanying drawings. The present invention is capable of various modifications and various forms, and specific embodiments are illustrated in the drawings and described in detail in the text. It is to be understood, however, that the invention is not intended to be limited to the particular forms disclosed, but on the contrary, is intended to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.

FIG. 1 is a perspective view showing a state where the eye-slip prevention device according to the present invention is mounted on a tire, and FIG. 2 is an exploded perspective view of an embodiment.

Referring to FIGS. 1 and 2, an eye-slip prevention device 100 according to an embodiment of the present invention includes a fixing part 102 and a detachable part 104. The fixed portion 102 is always mounted on the rim 20 of the wheel 10. The detachable portion 104 is not mounted normally but is stored in a trunk or the like and is mounted on the fixed portion 102 only when running on snow.

The fixing portion 102 includes a fixed disk 110, an adapter 120, and a cover 130. The fixed disk 110 is mounted on the rim 20 of the wheel 10 by an adapter 120. The adapter 120 is assembled to the wheel bolt on the side of the wheel 10, and may include a special nut, a fixture clip, a nut, a nut, a washer, and a bolt. The adapter 120 selectively couples a special nut or a fix clip according to a wheel bolt or a wheel nut that is coupled to the outside of the rim 20. If a screw is to be screwed onto the wheel bolt, Alternatively, when a special nut is screwed or a wheel nut is screwed to the wheel bolt, the wheel nut is covered with a fix clip on the outer side of the wheel nut. A special nut or a fixture clip may be selectively coupled to the fixed disk 110 so that the fixed disk 110 can be installed at the same height as the outer surface of the tire 30 according to the depth of the outer surface of the tire 30 and the depth of the rim 20. [ And a special nut or fixture clip can be selectively connected to the nut or the nut to adjust the height.

Fig. 3 is a front view of a preferred embodiment of the fixed disk of Fig. 2, and Fig. 4 is a sectional view taken along line A-A of Fig.

3 and 4, the fixed disk 110 is fastened to the rim 20 of the wheel 10 through the adapter 120, and a through hole 110a is formed at a central portion thereof. Four arc-shaped locking protrusions 110b protruding toward the center of the vehicle from the inner periphery of the arc-shaped locking protrusions 110a are formed in a circumferential direction so as to be spaced apart from each other by a predetermined distance, Holes 110c are disposed. And a plurality of fixing holes 110d are formed on the plate so as to be fixed by the adapter 120. [ Therefore, the inner diameter D2 between the arc-shaped latching protrusions 110b opposed to each other with respect to the inner diameter D1 of the penetration hole becomes shorter.

2, the fixing holes 110d of the fixed disk 110 correspond to the wheel bolts of all the wheel types existing through various types of fixing holes formed on the fixed disk 110 and the adapter 120, The fixed disk 110 is fixed to the rim 20 by coupling the fixing bolt to the nut hole formed on the other end surface of the long nut or the single nut. The outer surface of the fixed disk 110 thus mounted is covered with the lid 130 so that the outer surface of the fixed disk 110 is apparently beautiful. Therefore, even if the fixed disk 110 is always mounted, it can be well matched to the overall appearance of the vehicle body.

In this state, the lid 130 of the fixed disk 110 is detached before mounting the detachable part 104 on the eye or ice path.

The detachable portion 104 mainly includes a radial body 140 and a lock disk 150. The radial body 140 is fixed to the fixed disk 110 by mounting the radial body 140 on the fixed disk 110 and rotating the locking disk 150 in the locking direction by inserting the locking disk 150 into the fixed disk 110.

5 shows a front view of a preferred embodiment of the lock disc 150 of Fig. 2, Fig. 6 shows a sectional view taken along the line BB of Fig. 5, Fig. 7 shows a sectional view taken along the line CC of Fig. Fig. 9 is a rear view of the lock actuating body of Fig. 5; Fig.

5 to 9, the lock disk 150 includes a disk 152, a lock actuator 154, and a compression spring 156.

The circular plate 152 is formed by a plastic injection-molded two-stage donut shape, and a through hole 152a is formed at the center. A lock actuator 154 is slidably mounted on the inside of the through hole 152a.

A central protruding portion 152b protruding from the lower end edge of the through hole 152a of the disc 152 toward the fixed disc 110 is formed. The central protruding portion 152b is formed with four guide grooves 152c in the shape of a hollow cylinder, which is divided into four sides in the radial direction. Four arc-shaped latching protrusions 152d protruding in the radial direction are formed on the outer circumferential surface of the central protruding portion 152b except for the guide groove 152c so as to be circumferentially spaced apart from each other by a predetermined distance. The arc-shaped locking protrusions 152d protrude from the bottom surface of the circular plate 152 by a predetermined distance s. The predetermined interval s maintains an interval such that the arc-shaped locking protrusions 110b of the fixed disk 110 can be inserted by rotation. That is, a distance enough to accommodate the thickness of the arc-shaped locking protrusion 110b.

Two slide grooves 152f extending forward and backward are formed in the inner peripheral surface of the through hole 152a of the disk 152 at diametrically opposed positions and engaging grooves 152g are formed at the rear end of each slide groove 152f do. The tips of the slide grooves 152f communicate with the guide grooves 152c, respectively.

The horizontal straight distance d4 between the slide grooves 152f is shorter than the horizontal straight distance d1 between the guide grooves 152c. The horizontal straight distance d3 between the locking grooves 152g is longer than the horizontal straight distance d4 and shorter than the horizontal straight distance d2.

The lock actuating member 154 includes a + -shaped vertical plate 154a which is fitted between the slide grooves 152f and slides forward and rearward. A straight-handed handle 154b is integrally formed on the upper end of the vertical plate 154a. The straight handle 154b has a latching protrusion 154c protruding leftward or rightward in a horizontal direction with a horizontally rectangular plate with respect to the + vertical plate 154a. The latching protrusion 154c is caught by the latching grooves 152g and blocks the forward movement of the vertical plate 154a.

Shaped support plates 154d are formed on the four sides of the + vertical plate 154a. The four arc-shaped support plates 154d have a width enough to be inserted into the guide groove 152c in the form of a horizontal plate protruding radially from the four edges of the + vertical plate 154a. The arc-shaped pedestal plate 154d is fitted into the guide groove 152c and slides forward and rearward. The lower end of the compression spring 156 housed in the guide groove 152c is supported on the upper surface of the arc-shaped support plate 154d. An arc-shaped rotation cut-off step 154e protruding forward by a predetermined thickness is formed on the front surface of the arc-shaped support plate 154d. The projecting thickness of the arc-shaped rotation blocking step 154e is formed to be thicker than the spacing s. The arc-shaped rotation stopping jaw 154e is inserted into the guide groove 152c between the arc-shaped catching protrusions 152d to block the gap s between the bottom surface of the circular plate 152 and the arc-shaped catching protrusion 152d. The height h of the guide groove 152c entering from the front surface of the disk 152 is set such that the front surface of the arc-shaped rotation blocking step 154e is deeper than the front surface of the disk 152 in a state in which the compression spring 156 is housed inside. It has enough depth to enter.

The longest straight line length d2 between the four arc-shaped rotation blocking shoulders 154e is equal to the longest straight line length (outer diameter) of the arc-shaped locking projections 152d. The longest straight line length d4 between the arc-shaped rotation blocking shoulders 154e should satisfy the condition of D1> d2> D2. The longest straight line length between arc-shaped support plates 154d should satisfy the condition that the length d1 is d1 > D1.

Therefore, the four arc-shaped rotation cut-off jaws 154e intercept the four arc-shaped protrusions 110b to maintain the locked state, and thus, compared with the two arc-shaped rotation cut-off jaws 154e, It is possible to halve the breakage of the corner.

In addition, an insertion groove 154f for accommodating the edge 110e of the arc-shaped protrusion 110b of the fixed disk 110 may be further formed on both side walls of the arc-shaped rotation cut-off jaws 154e. The height of the insertion groove 154f is formed to a height enough to accommodate the thickness of the edge 110e of the projection 110b of the fixed disk 110. [ That is, when the edge 110e is inserted into the insertion groove 154f, the oscillation in the axial direction acts to deviate in a certain direction due to the elastic force of the restoring spring, so that the vibration can be suppressed.

The locking actuator 154 thus configured is inserted from the front of the central projection 152b of the circular plate 152 backward from the knob 154b so that both side ends of the vertical plate 154a are sandwiched between the slide grooves 152f When the arcuate support plate 154d is inserted between the guide grooves 152c and the end of the latching protrusion 154c of the handle 145b is bent into the engagement groove 152g through the slide groove 152f The latching protrusion 154c is engaged with the latching groove 152g while being spread in the left-right direction. Therefore, it can not be moved forward any more. Therefore, even if the lock actuating member 154 is forced forward by the restoring force of the compression spring 156, the locking protrusion 154c maintains the stop state.

When the handle 154b of the lock actuating member 154 is pulled backward, the lock actuating member 154 retracts along the sliding groove 152f and the guide groove 152c and the arcuate bearing plate 154d Compression. At this time, when the front surface of the arc-shaped rotation cut-off step 154e enters the inside of the guide groove 152c more than the front height of the disk 152, the lock state is released. When the force for pulling the handle 154b is removed, the arc-shaped rotation cut-off step 154e in the guide groove 152c protrudes forward higher than the bottom surface of the disk 152 due to the restoring force of the compression spring 156, .

10 and 11 are views for explaining the releasing and locking states according to the present invention.

10, in a state where the arc-shaped locking protrusions 152d of the locking disc 150 are aligned with the insertion holes 110c of the fixed disc 110, when the locking disc 150 is pressed toward the fixed disc 110 The four arc-shaped rotation cut-off protrusions 154e are pressed against the four arc-shaped locking protrusions 110b of the fixed disk 110 so that the locking operation body 154 retreats backward along the guide groove 152c. When the arc-shaped rotation stopping jaw 154e is moved to the front height of the disk 152, the lock disk 150 is rotated.

Referring to FIG. 11, when the lock disk 150 is rotated by 45 degrees in the counterclockwise direction, the arc-shaped locking protrusions 152d cover the arc-shaped locking protrusions 110b.

 The locking protrusion 154 protrudes between the insertion holes 110c due to the restoring force of the compression spring 156 so that the locking protrusion 154 protrudes from the original position, That is, in a locked state.

FIG. 12 is a view for explaining an unwinding prevention effect according to the present invention. FIG.

12, in the locked state, the side wall of the arc-shaped rotation blocking step 154e is struck by the edge 152e of the arc-shaped locking protrusions 110b of the fixed disk 110. As shown in FIG. That is, there is a clearance between parts within a certain error range, which is not precisely fitted to the manufacturing process. Since the fixed disk 110 is fixed to the wheel, it is rotated at the same high speed as the wheel. However, the detachable portion 104 including the radial body 140 and the lock disk 150 can not be rotated integrally with the wheel due to road surface resistance or the like, and is temporarily slipped and rotated within the clearance range. The sidewall of the arc-shaped rotation stopping jaw 154e is repetitively struck by the edge 110e of the arc-shaped locking protrusions 110b of the fixed disk 110 by the repetitive phenomenon of slipping and rotating.

Since the arc-shaped locking protrusions 110b of the fixed disk 110 are steel products of high strength and the arc-shaped rotation cut-off step 154e is a plastic injection-molded product, the arc-shaped rotation cut-off step 154e, which is a plastic injection- There is a possibility that the side wall of the side wall is damaged by the continuous impact. Furthermore, if the plastic injection molded part is frozen during the winter, it can be easily broken if subjected to continuous impact. When this portion is worn or damaged and removed, the arc-shaped locking protrusions 110b are rotated to the unlocked position on the arc-shaped rotation stopping jaw 154e, thereby releasing the locked state. The entire detachable portion 104 including the radial body 140 and the lock disk 150 may be detached and separated.

In the present invention, since the locking protrusion 110e is formed by the locking protrusion of the + shape compared to the conventional locking protrusion, the collision of the arc-shaped locking protrusions 110b is received in the four locking protrusions 154e, .

In the present invention, since the edge 110e of the arc-shaped locking protrusions 110b of the fixed disk 110 is inserted into the insertion groove 154f and the oscillation in the axial direction is oscillated in a certain direction by the elastic force of the restoring spring The axial vibration is suppressed. Moreover, the damage can be further reduced by dispersively absorbing the direct impact force applied to the side wall by the insertion groove 154f.

FIG. 13 is a front view of a lock disk of another embodiment according to the present invention, FIG. 14 is a front view of a lock disk of another embodiment according to the present invention, FIG. 15 is a front view of a lock actuator of another embodiment according to the present invention, 16 is a rear view of the lock operating body of Fig. In another embodiment, for the same similar structure in comparison with the above-described embodiment, only hundreds of the reference numerals are changed from 100 to 200, and the digits of the digits of the remaining digits and the digits of the digits of the digits are the same.

 Referring to FIGS. 13 to 16, the fixed disk 210 and the lock disk 250 of the other embodiment are different from the + -shaped structure of the above-described embodiment in that they have a Y-shaped structure, .

The fixed disk 210 has three arc-shaped latching protrusions 210a and three insertion holes 210c arranged at intervals of 120 degrees.

The locking disc 250 includes a disc 252 having three guide grooves 252c, a Y-shaped locking actuator 254 having three arcuate foot plates 254d, and three compression springs 256.

Therefore, the three arc-shaped locking protrusions 210b are dispersedly received by the three arcuate locking protrusions 254e formed on the three arc-shaped support plates 254d, so that the probability of unlocking can be reduced by about 30% have.

Also, in another embodiment of the present invention, insertion grooves 254f may be formed in both side walls of three arc-shaped rotation cut-off jaws 254e. In this case, the edge 210e of the arc-shaped catching protrusions 210b of the fixed disk 210 is inserted into the insertion groove 254f and the oscillation in the axial direction is oscillated in a certain direction by the elastic force of the restoring spring. Direction vibration is suppressed. Moreover, the damage can be further reduced by dispersively absorbing the direct impact force applied to the side wall by the insertion groove 254f.

Although the preferred embodiments of the anti-slip apparatus according to the present invention have been described above, the present invention is not limited thereto, and various modifications may be made within the scope of the claims, And this also belongs to the present invention.
