Description

Technical Field

[0001] The present disclosure mainly relates to a tire lock device.

Background Art

[0002] Conventionally, there have been many cases where automobiles are stolen by means of unlocking the door and starting the engine by so-called "relay attack" or "CAN invader", and countermeasures are urgently needed. Therefore, as countermeasures against such means, for example, an alarm device with a high deterrent effect on thieves and a retrofit immobilizer that requires electronic ID authentication for engine start are conceivable. However, retrofitting an alarm device or an immobilizer is costly.

[0003] On the other hand, as a device for preventing the theft of an automobile by mechanically restricting the rotation of the wheels even when the engine is started, the following tire lock is expected as a countermeasure against the above means (see, for example, Patent Documents 1 and 2).

[0004] Here, a tire lock is attached to the wheels of a parked automobile to obtain an anti-theft effect by restricting the rotation of the wheels, and includes the following first and second arms and a bridging portion. That is, the first and second arms are respectively hooked on the wheel from one side and the other side in the width direction of the wheel, and the bridging portion bridges between the first and second arms. And with such a configuration, the tire lock restricts the rotation of the wheel by the hooking of the first and second arms on the wheel.

[0005] However, in recent years, with the increase in the output of high-class cars targeted for theft, even when a tire lock is installed, due to the high output of the automobile itself, the wheels are rotationally driven, and the situation where the hooking of the first and second arms on the wheel is forcibly released and the automobile is carried away is increasing. Therefore, a configuration that enables enhancing the anti-theft effect against such a forcible method is desired.

Mode for Carrying Out the Invention

[0011] The mode for carrying out the present disclosure will be described in detail by the following examples.

Example

[0012] 〔Configuration of Example 1〕 The tire lock device 1 of Example 1 will be described with reference to FIGS. 1 to 5 (in the following description, the tire lock device 1 may be abbreviated as the device 1). The device 1 is attached to the wheel 3 of a parked automobile to regulate the forward and backward movement of the automobile, and includes the following tire lock 4 and wheel stopper 5.

[0013] First, the tire lock 4 engages with the wheel 6 that constitutes the wheel 3 to regulate the rotation of the wheel 3, and has the following first and second arms 7, 8, and a bridging portion 9. First, the first and second arms 7 and 8 are hooked onto the wheel 6 from one side and the other side in the width direction of the wheel 3, respectively. Further, the bridging portion 9 is a portion that bridges between the first and second arms 7 and 8, and functions as a width adjustment portion that increases or decreases the distance in the width direction between the first and second arms 7 and 8 by expanding and contracting itself.

[0014] Hereinafter, the first and second arms 7 and 8 and the bridging portion 9 will be sequentially described. First, the first and second arms 7 and 8 are provided in an arc shape and have substantially the same shape as each other. Further, the first and second arms 7 and 8 are each a single metal body having a U-shaped cross section, and are provided so as to open toward the outer peripheral side of the arc and the inner peripheral side is closed.

[0015] Hereinafter, for the sake of convenience of explanation, in the first and second arms 7 and 8, among the three walls of the U-shaped cross section, the walls closing the inner peripheral side may be respectively referred to as inner peripheral wall portions 7a and 8a, and the two walls spanning the inner and outer peripheries may be respectively referred to as one wall portion 7b, 8b and the other wall portion 7c, 8c.

[0016] The first arm 7 has the following main body portion 7A, tip portion 7B, and root portion 7C. First, the main body portion 7A is provided in an arc shape, and forms a relative rotation structure with a cylindrical body 11 that forms a part of the bridging portion 9 on the side of the root portion 7C rather than the center. That is, an intersection hole 12 through which the cylindrical body 11 intersects and passes is provided in the inner peripheral wall portion 7a on the side of the root portion 7C rather than the center inside the main body portion 7A. Further, a pin 13 is assembled so as to penetrate one of the other wall portions 7b and 7c in the vicinity of the intersection hole 12 and the cylindrical body 11, and the pin 13 functions as a rotation axis portion for relative rotation between the first arm 7 and the cylindrical body 11. Note that the intersection hole 12 is provided long in the circumferential direction so that relative rotation between the first arm 7 and the cylindrical body 11 is possible.

[0017] Further, the tip portion 7B is continuous with the main body portion 7A so as to bend toward the inner peripheral side of the arc of the main body portion 7A. Furthermore, the base portion 7C is continuous with the main body portion 7A so as to bend toward the outer peripheral side of the arc of the main body portion 7A, and a mutual support portion 7D, which will be described later, is attached to the same side as the inner circumference of the main body portion 7A. The mutual support portion 7D is a metal body provided with a U-shaped cross section and is fixed to the base portion 7C so as to open toward the same side as the inner circumference of the main body portion 7A.

[0018] The second arm 8 also has a main body portion 8A, a tip portion 8B, and a base portion 8C similar to those of the first arm 7. First, the main body portion 8A is provided in an arc shape and forms a relative rotation structure with a rod-shaped body 14 that forms part of the cross-linking portion 9 on the side of the base portion 8C rather than the center. That is, an intersection hole 15 through which the rod-shaped body 14 intersects and passes is provided in the inner peripheral wall portion 8a on the side of the base portion 8C rather than the center inside the main body portion 8A.

[0019] Also, a pin 16 is assembled so as to penetrate one of the wall portions 8b and 8c near the intersection hole 15 and the rod-shaped body 14, and the pin 16 functions as a rotation axis portion for relative rotation between the second arm 8 and the rod-shaped body 14. The intersection hole 15 is provided long in the circumferential direction so that relative rotation between the second arm 8 and the rod-shaped body 14 is possible.

[0020] The tip portion 8B is continuous with the main body portion 8A so as to bend toward the inner peripheral side of the arc of the main body portion 8A. Furthermore, the base portion 8C is continuous with the main body portion 8A so as to bend toward the outer peripheral side of the arc of the main body portion 8A, and a mutual support portion 8D similar to the mutual support portion 7D is attached to the same side as the inner circumference of the main body portion 8A.

[0021] The first and second arms 7 and 8 form a relative rotation structure as follows. That is, the first and second arms 7 and 8 are arranged such that the inner peripheral sides of the respective main body portions 7A and 8A face each other, and also, among the respective mutual support portions 7D and 8D, one wall portions 7b and 8b overlap each other, and the other wall portions 7c and 8c overlap each other. A pin 17 is assembled so as to penetrate the overlapping one wall portions 7b and 8b and the other wall portions 7c and 8c, and the pin 17 functions as a rotation axis portion for relative rotation between the first and second arms 7 and 8.

[0022] Next, in order for the crosslinked portion 9 to function as the above-described width adjustment portion, in addition to the above-described cylindrical body 11 and rod-shaped body 14, it has the following lock base 19. First, the cylindrical body 11 has the following cylindrical portion 11a and rotating base portion 11b. That is, the cylindrical portion 11a is a portion where the rod portion 14a of the rod-shaped body 14 is coaxially fitted and passes through the intersecting hole 12. Further, the rotating base portion 11b has a hole through which the pin 13 passes and is accommodated between one wall portion 7b and the other wall portion 7c of the first arm 7.

[0023] Further, the rod-shaped body 14 has the following rod portion 14a and rotating base portion 14b. That is, the rod portion 14a is a portion that is coaxially fitted into the cylindrical portion 11a and passes through the intersecting hole 15. Further, the rotating base portion 14b has a hole through which the pin 16 passes and is accommodated between one wall portion 8a and the other wall portion 8b of the second arm 8. Further, a plurality of engaging grooves 20 for engaging with an engaging claw (not shown) of the lock base 19 are provided in the rod portion 14a so as to be arranged in the axial direction. Furthermore, the lock base 19 has a through hole 19a through which the cylindrical portion 11a passes, and an engaging claw is inserted and removed from the through hole 19a by operating an insertion key (not shown).

[0024] With the above configuration, in the tire lock 4, the distance in the width direction between the first and second arms 7 and 8 can be adjusted as follows according to the width of the wheel 3. That is, by operating the insertion key to retract the engaging claw from the through hole 19a to release the engagement between the engaging claw and the engaging groove 20, in this state, for example, by grasping the tip portions 7a and 8a of the first and second arms 7 and 8 and widening or narrowing the distance between the tip portions 7a and 8a, the distance in the width direction between the first and second arms 7 and 8 is adjusted.

[0025] At this time, the first arm 7 and the cylindrical body 11 rotate relative to each other around the pin 13, the second arm 8 and the rod-shaped body 14 rotate relative to each other around the pin 16, and the first and second arms 7 and 8 rotate relative to each other around the pin 17. Further, the rod portion 14a is coaxially inserted into and removed from the cylindrical portion 11a. Then, when the distance in the width direction between the first and second arms 7 and 8 is adjusted to a desired size, the engaging claws are protruded into the through holes 19a by operating the insertion key and engaged with the engaging grooves 20 to fix the distance in the width direction between the first and second arms 7 and 8.

[0026] Next, the wheel stopper 5 abuts against the tread portion 21t of the tire 21 constituting the wheel 3 to regulate the forward and backward movement of the wheel 3, and has, for example, the following configuration. That is, the wheel stopper 5 is, for example, a substantially hexahedron composed of a lower surface 5a, an upper surface 5b, a front surface 5c, a rear surface 5d, and two side surfaces 5e and 5f, and is provided with a resin as a material. Here, the lower surface 5a is a rectangular surface in contact with the road surface, the upper surface 5b is a rectangular surface parallel to the lower surface 5a and located on the opposite side of the lower surface 5a, and has the same width as the lower surface 5a and a length smaller than that of the lower surface 5a.

[0027] The front surface 5c is a substantially partial cylindrical surface with a small curvature, and is provided so as to be recessed toward the rear surface 5d between one side edge in the length direction of the lower surface 5a and one side edge in the length direction of the upper surface 5b. The wheel stopper 5 is used such that the front surface 5c abuts against or faces the tread portion 21t.

[0028] The rear surface 5d is a rectangular surface and is provided between the other side edge in the length direction of the lower surface 5a and the other side edge in the length direction of the upper surface 5b. Further, of the two side surfaces 5e and 5f, the side surface 5e located on one side in the width direction is a substantially trapezoidal surface defined by one side edge in the width direction of each of the lower surface 5a, the upper surface 5b, the front surface 5c, and the rear surface 5d. Similarly, the side surface 5f located on the other side in the width direction is a substantially trapezoidal surface defined by the other side edge in the width direction of each of the lower surface 5a, the upper surface 5b, the front surface 5c, and the rear surface 5d.

[0029] The wheel stopper 5 also has a receiving portion 23 that receives and holds a part of the bridging portion 9. Then, the device 1 is used in a state where the receiving part 23 holds the bridging part 9, the first and second arms 7 and 8 are caught by the wheel 6, and further, the wheel stopper 5 contacts or faces the tread part 21t. Hereinafter, the receiving part 23 will be described in detail.

[0030] The receiving part 23 is a slit having the following vertical direction guiding part 23a and horizontal direction guiding part 23b (hereinafter, the receiving part 23 may be referred to as the slit 23). First, the vertical direction guiding part 23a is the part where the presence of the road surface is assumed in the wheel stopper 5, that is, it opens to the lower surface 5a and the bridging part 9 can move toward the side opposite to the side where the presence of the road surface is assumed, that is, toward the upper surface 5b. More specifically, the vertical direction guiding part 23a forms a linear opening parallel to the width direction on the lower surface 5a, and extends while maintaining a state parallel to the width direction, toward the upper surface 5b, and is also open to the two side surfaces 5e and 5f substantially parallel to the front surface 5c.

[0031] Also, the horizontal direction guiding part 23b is connected to the vertical direction guiding part 23a and is the part where the bridging part 9 can move toward the side where the tire 21 is assumed to be present, that is, toward the front surface 5c. More specifically, the horizontal direction guiding part 23b extends from the end on the side opposite to the opening of the vertical direction guiding part 23a, while maintaining a state parallel to the width direction, toward the front surface 5c, and is also open to the two side surfaces 5e and 5f parallel to the lower surface 5a and the upper surface 5b.

[0032] Then, the bridging part 9 enters from the opening of the vertical direction guiding part 23a and moves through the vertical direction guiding part 23a, and then moves toward the front surface 5c through the horizontal direction guiding part 23b, and is held by the slit 23. Note that a part of the bridging part 9 held by the slit 23 is, for example, the cylindrical part 11a of the cylindrical body 11, and the gaps between the vertical direction guiding part 23a and the horizontal direction guiding part 23b are both provided slightly wider than the cylindrical part 11a.

[0033] 〔Mounting method of Example 1〕 The mounting method of the device 1 of Example 1 will be described with reference to the drawings. First, the tire lock 4 and the wheel stopper 5 are integrated in advance to form the device 1. That is, the cylindrical portion 11a is inserted into the slit 23 and moved in the order of the vertical direction guiding portion 23a and the horizontal direction guiding portion 23b, and the cylindrical portion 11a is held in the slit 23. At this time, the cylindrical portion 11a is inserted into the slit 23 so that the front surface 5c is located on the side of the tip portions 7B and 8B, and the back surface 5d is located on the side of the base portions 7C and 8C.

[0034] Also, in the tire lock 4, the engaging claw is retracted from the through hole 19a by operating the insertion key to release the engagement between the engaging claw and the engaging groove 20. In this state, grasp the tip portions 7B and 8B of the first and second arms 7 and 8 respectively, widen the distance between the tip portions 7B and 8B, and hook the respective tip portions 7B and 8B from behind the rear wheel 3 of the automobile, for example, to the wheel 6 while the automobile is parked. Then, by operating the insertion key, the engaging claw is protruded into the through hole 19a and engaged with the engaging groove 20.

[0035] As described above, the device 1 is mounted on the rear wheel 3. That is, the slit 23 holds the cylindrical portion 11a, the first and second arms 7 and 8 are hooked on the wheel 6 of the rear wheel 3, and further, the wheel stopper 5 abuts on the tread portion 21t of the rear wheel 3.

[0036] 〔Effect of Example 1〕 The device 1 of Example 1 is mounted on the wheel 3 of a parked automobile to restrict the forward and backward movement of the automobile, and includes the following tire lock 4 and wheel stopper 5. First, the tire lock 4 is hooked on the wheel 6 constituting the wheel 3 to restrict the rotation of the wheel 3. Also, the wheel stopper 5 abuts on the tread portion 21t of the tire 21 constituting the wheel 3 to restrict the forward and backward movement of the wheel 3.

[0037] Furthermore, the tire lock 4 has first and second arms 7, 8, and a crosslinked portion 9 as follows. Here, the first and second arms 7, 8 are hooked onto the wheel 6 from one side and the other side in the width direction of the wheel 3, respectively, and the crosslinked portion 9 bridges between the first and second arms 7, 8. Furthermore, the wheel stopper 5 has a slit 23 as a receiving portion that receives and holds a cylindrical portion 11a that is at least a part of the crosslinked portion 9. Then, the slit 23 holds the cylindrical portion 11a, the first and second arms 7, 8 are hooked onto the wheel 6, and furthermore, the wheel stopper 5 is used in a state where it contacts or faces the tread portion 21t.

[0038] As a result, even if an attempt is made to forcibly move the vehicle forward or backward with the device 1 attached to the wheel 3, the wheel stopper 5 is sandwiched between the wheel 3 and the crosslinked portion 9, so that the hooking of the first and second arms 7, 8 onto the wheel 6 cannot be released. For this reason, it becomes possible to prevent the rotational restriction of the wheel 3 by the tire lock 4 from being forcibly released by the high output of the vehicle itself, and the anti-theft effect by the tire lock 4 can be enhanced. Also, by making the receiving portion the slit 23, the receiving portion can be easily provided in the wheel stopper 5.

[0039] Also, the slit 23 has a vertical direction pointing portion 23a and a horizontal direction pointing portion 23b as follows. That is, the vertical direction pointing portion 23a opens to the lower surface 5a on the side assuming the presence of the road surface, and the cylindrical portion 11a can move toward the upper surface 5b on the side opposite to the side assuming the presence of the road surface. The horizontal direction pointing portion 23b is connected to the vertical direction pointing portion 23a, and the cylindrical portion 11a can move toward the front surface 5c on the side assuming the presence of the tire 21.

[0040] Then, the cylindrical portion 11a enters from the opening of the vertical direction pointing portion 23a, that is, the opening of the lower surface 5a, moves through the vertical direction pointing portion 23a, and then moves toward the front surface 5c through the horizontal direction pointing portion 23b, and is held by the slit 23. As a result, the cylindrical portion 11a becomes difficult to come out of the slit 23, so that the anti-theft effect by the tire lock 4 can be further enhanced.

[0041] 〔Example 2〕 According to the apparatus 1 of Example 2, the slit 23 has a plurality of lateral direction directing portions 23b. More specifically, for example, as shown in FIG. 6, two lateral direction directing portions 23b similar to those of Example 1 are connected to the longitudinal direction directing portion 23a. Thereby, since the lateral direction directing portion 23b into which the cylindrical portion 11a is inserted can be selected according to the size of the wheel 3, by preparing one apparatus 1, for example, for both small vehicles and large vehicles, the anti-theft effect by the tire lock 4 can be enhanced.

[0042] 〔Example 3〕 According to the apparatus 1 of Example 3, the longitudinal direction directing portion 23a and the lateral direction directing portion 23b constituting the slit 23 are respectively in the following modes (see FIG. 7). First, the lateral direction directing portion 23b opens on the side opposite to the side where the tire 21 is assumed to exist in the wheel stopper 5, that is, on the back surface 5d. And the cylindrical portion 11a can move toward the side where the tire 21 is assumed to exist in the lateral direction directing portion 23b, that is, toward the front surface 5c.

[0043] Also, the longitudinal direction directing portion 23a is connected to the lateral direction directing portion 23b, and the cylindrical portion 11a can move toward the side opposite to the side where the road surface is assumed to exist in the longitudinal direction directing portion 23a, that is, toward the upper surface 5b. And the cylindrical portion 11a enters from the opening of the lateral direction directing portion 23b on the back surface 5d, moves through the lateral direction directing portion 23b, and then moves through the longitudinal direction directing portion 23a toward the upper surface 5b, and is held by the slit 23.

[0044] 〔Example 4〕 According to the device 1 of Example 4, as shown in FIG. 8, when viewed from the upper surface 5b, the wheel stopper 5 is in a form that is partially missing between the two side surfaces 5e and 5f. That is, the wheel stopper 5 of Example 4 has portions 5A and 5B on one side and the other side in the width direction, and a connecting portion 5C that connects the portions 5A and 5B. Here, the portion 5A has a slit 23A that houses the cylindrical portion 11a, and the portion 5B has a slit 23B that houses the rod portion 14a. Note that both the slits 23A and 23B have a longitudinal direction guiding portion 23a and a lateral direction guiding portion 23b similar to the slit 23 of Example 1.

[0045] Also, the missing portion between the portions 5A and 5B is provided so that the lock base 19 does not interfere three-dimensionally when moving the cylindrical portion 11a and the rod portion 14a into the slits 23A and 23B, respectively. For this reason, the wheel stopper 5 is integrated with the tire lock 4 so as to straddle the lock base 19.

[0046] As described above, according to the device 1 of Example 4, the wheel stopper 5 can hold the cross-bridge portion 9 with both the cylindrical body 11 and the rod-shaped body 14. For this reason, when attempting to forcibly move the vehicle forward or backward with the device 1 mounted on the wheel 3, the wheel stopper 5 is more firmly clamped between the wheel 3 and the cross-bridge portion 9. For this reason, the anti-theft effect by the tire lock 4 can be further enhanced.

[0047] 〔Modification Example〕 Various modification examples can be considered without departing from the gist of the present invention. For example, according to the device 1 of Example 1, the wheel stopper 5 held only the cylindrical portion 11a inside the cross-bridge portion 9, but two wheel stoppers 5 may be prepared and individually held by the wheel stoppers 5 on the cylindrical portion 11a and the rod portion 14a, respectively. Thereby, the same effect as the wheel stopper 5 of Example 4 can be obtained. Also, for example, protrusions may be provided on the inner wall of the slit 23 to make it difficult for the cylindrical portion 11a or the like to return in the direction of coming off.
