Description

The present invention relates to a motorcycle anti-theft device,
By combining the load carrier with the wheel lock bar, the inconvenience of storing and removing the wheel lock bar is eliminated.Also, by using the load carrier support as the lock bar lock, the wheel lock can be used exclusively. It is possible to eliminate inconveniences in terms of manufacturing cost and appearance of the vehicle body due to the provision of metal fittings on the side of the vehicle body.

[Conventional technology]

As a theft prevention device for a motorcycle or the like, a handle lock device and a wheel lock device are known, and a case provided with only the handle lock device, a case provided with only the front wheel lock device, a case provided with only the rear wheel lock device, and a combination thereof. There are various cases such as equipped cases.

A so-called chain lock is conventionally often used as a front wheel lock device and a rear wheel lock device.However, in a motorcycle, a case provided with a lock device using a lock bar as a rear wheel lock device in order to further secure the protection. is there.

In this lock device using a lock bar, the lock bar is passed through a rear wheel, and both ends of the lock bar are locked by a lock device fixed to a rear side portion of the vehicle body.

However, in the lock device using the conventional lock bar, the lock bar is bulky unlike a lock chain or the like, and has no flexibility, so that it is inconvenient to store when not in use and take out when in use. There is a problem that special equipment for storage is required because the lock must be firmly fixed so as not to be loosened. In addition, since a dedicated metal fitting for locking both ends of the lock bar must be specially provided on the rear side of the vehicle body, the cost is increased and the appearance of the vehicle body is impaired. Because of these problems, locking devices with locking bars are less commonly used, even though they offer the best protection.

[Problems to be solved by the invention]

The present invention improves the practicability of the wheel lock device by the lock bar, so that its storage is simple, easy and reliable,
The U-shaped lock bar can be easily and easily attached to the rear wheel lock position without specially installing special lock hardware.
It is an object to devise a storage mechanism and a lock mechanism.

[Means for solving the problem]

The measures taken to solve the above problems are the following elements (a)-
(G).

(A) The wheel lock bar is a U-shaped lock bar and the width thereof is larger than the width of the rear wheel. (B) A pair of front and rear holding brackets for horizontally holding the U-shaped lock bar are provided on both sides of the rear of the vehicle body. (C) A horizontal locking hole is provided in the front holding metal, and a horizontal through hole is provided in the rear holding metal. (D) A downward locking hole is provided in the front holding metal or the rear holding metal. (E) With the U-shaped rear portion of the U-shaped lock bar protruding rearward of the seat, the front horizontal portion of the lock bar is detachably held by front and rear holding metal fittings, and a locking device for the front holding metal fitting is provided. (F) a locking device that locks and locks the tip of a substantially vertical U-shaped lock bar to one of the front and rear holding brackets; (g) the U-shaped lock bar Bend the rear part Square to the horizontal portion and the side surface shape of displacing upward from the front horizontal portion.

(Operation)

Normally, the front horizontal portion (linear portion) of the U-shaped lock bar is passed through the horizontal through hole of the rear holding bracket, and the tip is inserted into the horizontal locking hole of the front holding bracket to lock the front holding bracket. Locked by device. In this state, the U-shaped lock bar is horizontal and the U-shaped rear portion is fixed to both sides of the rear of the vehicle body with the U-shaped rear portion protruding to the rear of the seat, so the U-shaped lock bar is used as a luggage carrier and can be used without permission. Removal can be prevented.

Remove the U-shaped lock bar from the holding bracket, pass one end of the U-shaped locking bar through the rear wheel, place the U-shaped lock bar in a substantially vertical position, and insert both ends of the U-shaped locking bar into the downward locking holes of the holding bracket on either front or rear. When locked, the rear wheel is reliably prevented from rotating by the U-shaped lock bar.

When a U-shaped lock bar is used as a wheel lock bar, its tip is fixed by a holding bracket when the U-shaped lock bar is used as a luggage carrier. There is no need to provide it, and since the U-shaped lock bar is used as a luggage carrier, there is no need to store it when not in use, and when locking the wheels, it is necessary to remove the fixing device in the storage part and take it out there There is no. Therefore,
There is no need for a storage space or a mounting bracket.

Also, since the front and rear holding brackets are usually the holding brackets for the luggage carrier, their presence is not unnatural at all in appearance, and the holding brackets that hold the lock bar exclusively for wheel locking are attached to the side of the vehicle body Its appearance is much better.

In addition, U
Since the tip of the lock bar is inserted and locked, there are differences in the form of the rear wheel spokes (for example, plate spokes, wire spokes, etc.), differences in the size of the rear wheel, and differences between the rear wheel and the rear of the vehicle body. Depending on the positional relationship, it is possible to select whether to provide a downward locking hole and a locking device therefor in one of the front and rear holding brackets.

Further, since the U-shaped lock bar is formed by bending the rear portion thereof to have a rear horizontal portion displaced upward from the front horizontal portion, the U-shaped lock bar is used to lock the rear wheel (lock bar). Is used in a vertical position)
Thus, the rear horizontal portion is displaced rearward from the front horizontal portion. Therefore, even when the front end of the lock bar is held by the front holding metal, the rear portion of the U-shaped lock bar can be prevented from interfering with the hub of the rear wheel. The same can be used regardless of whether the shaped lock bar is held by the front holding metal or the rear holding metal.

〔Example〕

At the rear part of the body frame 2 of the motorcycle 1, there are a pair of mutually parallel seat rails 3a, 3b formed integrally therewith, and brackets 10a, 10b and 11a, 11b are provided on the lower surfaces thereof.
, Two sets of holding fittings 12a, 12b and 13a, 13b are fixed at predetermined intervals.

The front holding fitting 12a has a locking device 15 having a substantially horizontal locking hole on the rear end surface and a key hole on the outer surface. Further, a locking hole is provided on the rear surface of the opposite side of the holding bracket 12b which forms a pair with the U-shaped lock bar 20 when the U-shaped lock bar 20 is used as a load carrier.

The rear holding brackets 13a, 13b are provided with horizontal through holes 17a, 17b into which the linear portion of the U-shaped lock bar 20 is inserted, and further provided with downward locking holes on the lower surfaces of the holding brackets 13a, 13b. ing. Further, a locking device 16 having a key hole is built in the holding bracket 13a.

The locking device 15 of the holding fitting 12a and the locking device 16 of the holding fitting 13a have lock claws biased by a spring, and are automatically locked when the tip of the U-shaped lock bar 20 is inserted into the locking hole. , The key is unlocked.

The mounting structure of the holding bracket to the vehicle body, its mounting height, and the like are determined by the shape and structure of the vehicle body frame of each vehicle, and the supporting height suitable for using the U-shaped lock bar as a luggage carrier. It may be appropriately devised in consideration of the above.

The U-shaped lock bar 20 is made of a hard rod-shaped member, and has cutouts 20a and 20b at its both ends to which the lock claws are engaged. The U-shaped lock bar 20 is bent upward at the rear portion thereof and rises upward, and the rear horizontal portion 22 is connected to the front horizontal portion 21.
It has a side surface shape displaced upward.
This configuration is convenient for supporting the load by the rear horizontal portion 22 when used as a load carrier. The height of the upward displacement of the rear horizontal portion 22 is appropriately selected in consideration of the relationship between the position of the holding bracket in each vehicle and the load supporting height, the positional relationship with the rear fender 8, and the like. I just need. Further, the U-shaped lock bar is provided with a plurality of hooks 23 for fixing the load to the U-shaped lock bar 20 when the U-type lock bar is used as a load carrier. Holding bracket 1 at the lower rear of the seat rails 3a, 3b
The U-shaped lock bar 20 is inserted into the horizontal through holes 17a, 17b of the 3a, 13b from the rear, and the tip thereof is further attached to the front holding bracket 12
Insert into the lock holes of a and 12b. As a result, the tip of the U-shaped lock bar 20 is locked by the locking device 15 of the holding fitting 12a, and the U-shaped lock bar 20 is firmly fixed to the vehicle body in a substantially horizontal posture, and is used as a load carrier.
Since the holding device 12a is provided with the locking device 15 which is unlocked by a key, it is to prevent the U-shaped lock bar 20 from being removed without permission when used as a luggage carrier. As an alternative, a simple hand-operated lock mechanism that can firmly fix the tip of the U-shaped lock bar may be used.

The locking device 15 of the holding bracket 12a is unlocked with a key, and the U-shaped lock bar 20 is pulled out rearward. Thereafter, one of the front horizontal portions (linear portions) 21 of the U-shaped lock bar 20 is passed through the rear wheel 4, the U-shaped lock bar 20 is set to a substantially vertical posture (the posture of B in FIG. 1), and the tip is held rearward. The metal fittings 13a and 13b are engaged with the vertical locking holes. When the tip of the linear portion 21 of the U-shaped lock bar is inserted into the downward locking hole of the holding bracket 13a, the engaging claw of the locking device 16 engages with the notch 20a and is automatically locked. Therefore, the U-shaped lock bar 20 is fixed to the vehicle body in a substantially vertical posture passed through the rear wheel 4, and the rear wheel 4 is locked by the U-shaped lock bar.

When the U-shaped lock bar 20 is used to lock the rear wheel 4, the tip of the U-shaped lock bar 20 is engaged with the downward locking hole of the rear holding bracket 13a.
Since the positional relationship between b and the rear wheel is substantially as shown in FIG. 1, and since the U-shaped lock bar also serves as a load carrier, its actual length is considerably long. This is because the rear holding brackets 13a and 13b are more convenient to use for holding the distal end than the front holding brackets 12a and 12b.

In the embodiment described above, the holding and locking when the U-shaped lock bar is mounted in the vertical state is performed by the rear holding bracket, but the holding and locking when the U-shaped lock bar is mounted vertically and the locking are performed by the front holding. When using the metal fittings 12a and 12b, a downward locking hole may be provided on the lower surface thereof.

Which of the front and rear holding brackets should be used when mounting the U-shaped lock bar vertically is determined in consideration of the positional relationship between the seat rail and the rear wheel of each vehicle, the actual length of the U-shaped lock bar, and the like. Then, an appropriate selection may be made.

When the U-shaped lock bar is mounted in the vertical state, the rear horizontal portion 22 is displaced rearward from the front horizontal portion 21 (see the lock bar shown by a broken line in FIG. 1). Therefore, even when the front end of the U-shaped lock bar is held by the front holding metal, the rear portion (the lower portion in the vertically mounted state) does not interfere with the hub of the rear wheel 4. Reference numeral 5 denotes a spoke, 6 denotes a swing arm, and 7 denotes a cushion unit.

〔The invention's effect〕

As described above, by making the wheel lock bar a U-shaped lock bar and making its width larger than the width of the wheel,
Since the luggage carrier and the wheel lock bar can be used in common, and it is firmly fixed to the holding bracket as a luggage carrier in a normal traveling state, a lock bar dedicated to wheel lock is not required. Storage department,
There is no need for a special fixing bracket for fixing the lock bar so that the lock bar can be easily attached to and detached from the storage portion. Therefore, it is extremely advantageous in terms of manufacturing cost and storage space.

In addition, since it is also used as a holding bracket when used as a luggage carrier and a holding bracket when used to lock wheels, a special fixing bracket for fixing the lock bar to the vehicle body with the wheels locked is required And therefore,
This is extremely advantageous in terms of manufacturing cost and appearance.

Furthermore, the straight part of the U-shaped lock bar is inserted into the pipe side frame provided on the loading platform, locked with a set screw, pulled out from the pipe side frame, passed through the rear wheel, and the tip is provided at the rear of the loading platform. The U-shaped lock bar is inserted into the short tube, and the tip of the U-shaped lock bar is protruded upward. In this state, an appropriate lock is attached to the tip and the lock is locked, so that the vehicle is stolen. The thing which can be used for a preventer is known (Japanese Utility Model Publication No. 31-18818). This is U
U-shaped lock bar is also used as luggage carrier
This solves the problem of storage when the lock bar is not in use. On the other hand, in the present invention, a downward locking hole is provided in one of the front and rear holding brackets provided on the side surface of the rear part of the vehicle body,
The rear wheel is locked by inserting the tip of the U-shaped lock bar into it, so the difference in spoke configuration of the rear wheel, the difference in the size of the rear wheel, and the positional relationship between the rear wheel and the rear of the vehicle body Accordingly, the metal fitting for holding the tip of the lock bar in the vertical state can be selected as one of the metal fittings before and after.
Since the rear part of the shape lock bar is bent at the rear part and the rear horizontal part is displaced upward with respect to the front horizontal part, when locking the rear wheel by this, the rear horizontal part is The rear portion of the U-shaped lock bar interferes with the hub of the rear wheel even when the front end of the lock bar is held vertically by the holding metal fittings. The same thing can be used regardless of whether the U-shaped lock bar used as the lock bar is held by the front holding metal or the rear holding metal.

Further, when the known U-shaped lock bar is vertically mounted, its tip is projected upward, and an appropriate lock is attached to this tip to remove the U-shaped lock bar from the "short pipe 6". U
It is inevitable that the tip of the lock bar protrudes significantly upward from the "short pipe 6". Therefore, there is a danger that the part protruding upward will be caught by clothes or the like of a person,
In addition, there is a possibility that the distal end portion may be bent, which may hinder the detachment from the short tube 6, and there is a problem that its practicality is poor. No problem. This is also a great advantage of the invention.
