DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail based on illustrated embodiments. FIG. 1 is a perspective view of main members of a fixing device according to an embodiment of the present invention. In the figure, reference numeral 1 denotes a hook attached to the bottom surface 2a of the bag 2, and 11 denotes a hook 1
This is a lock mechanism for locking and fixing the lock. The hook 1
As shown in the cross-sectional view of FIG. 6, there are inner and outer bottom plate plates 3 and 4 which are fixed by riveting so as to sandwich the entire bottom surface of the bag 2 from inside and outside. At the center of the outer surface of the outer bottom plate 4, a latching piece 5 is attached. The latching piece 5 is formed by providing an elongated base 6 with a notch-like gripping latch 7, and fixing the base 6 to the outer bottom plate 4 with the latch 7 facing downward. I have. The hanging piece 5 directly connects the hanging part 7 without the base part 6.
It may be fixed to the outer bottom plate 4. In addition, the hook 7 does not necessarily have to have an open handle as long as the hook 7 cannot be detached from the lock mechanism 11 when locked.

The lock mechanism 11 is embedded in a substrate 12 attached to the bottom of the front basket 9 of the motorcycle 8 via appropriate fixing means such as bolts and nuts (see FIG. 2). The front basket 9 has a sufficient volume to accommodate the bag 2. A receiving body 13 that forms a part of the lock mechanism 11 is fixed to a substantially central portion of the substrate 12. The receiving body 13 is formed by bending a hard plate material into a substantially U-shaped cross section having a groove 13 a capable of receiving the retaining piece 5. The groove 13a is opened upward.

An operating rod 14 forming a part of the lock mechanism 11 is mounted in the substrate in a direction perpendicular to the receiving body. The operating rod 14 has a rod body 16 inserted into a cylindrical casing 15 as shown in FIGS. The rod body 16 has a forwardly inclined surface 16 at the tip.
have a. The rod body 16 includes a compression spring 17.
And the inclined surface 16a penetrates into the groove from one side wall of the receiving body 13 so as to cross the groove. A sufficient space is provided between the tip of the rod body 16 that has entered the groove and the bottom wall of the groove to allow the hooking portion 7 to enter. Stepped portions 16b are formed at the lower ends of both rear ends of the rod body 16.

A rotating shaft 18 is supported at the rear of the casing 15 so as to penetrate the casing 15 in the vertical direction.
A flat fan-shaped engaging piece 18a protrudes from the rotation shaft 18 around its axis. The engagement piece 18a engages with the step 16b at the side end thereof with the rotation of the rotation shaft 18, and retreats the rod body 16 against the urging force of the compression spring 17. A release lever 19 for rotating the rotating shaft 18 is attached to a lower end of the rotating shaft 18. One end of a wire 20 is connected to the release lever 19. Wire 20
Is pulled out of the substrate 12 and is connected to an operating member (not shown) provided, for example, near the handle so as to be able to be pulled. Reference numeral 16c in the figure denotes a body opening of the rod body 16, and reference numeral 15a denotes a retaining piece that contacts the rear end of the body opening 16c and prevents the rod body 16 from falling forward.

The use state will be described. When the bag 2 containing valuables or the like is put in the basket, the latching portion 7 of the bag bottom surface 2a enters the groove of the receiving body 13 and pushes the tip of the rod body 16 in the groove. Since the front end of the rod body 16 has a downwardly inclined surface 16a, this pressing force acts as an acting force for retracting the rod body 16 as seen in FIG. The rod body 16 which has retreated against the urging force of the compression spring 17 is released from the above-mentioned pressing force when the latching portion 7 enters the groove bottom, and moves forward by the urging force of the compression spring 17. The rod body 16 that has returned has its tip positioned between the hook 7 and the base 6 of the hook 1,
Lock the hook 1. Since the bottom of the bag 2 is fixed by the lock between the rod body 16 and the hook 1, the bag 2 cannot be forcibly taken out of the basket 9.
Further, since the fixing of the bag 2 is performed at the bottom of the bag in this manner, it is difficult to recognize from outside that such a fixing device is acting while the motorcycle 8 is running, and it may stimulate a snatcher. Absent. Further, when the motorcycle accidentally falls down, the bag 2 does not roll out of the basket 8.

To release the lock, the operating member is operated to pull the wire 20. When the pulled wire 20 rotates the rotating shaft 18 via the release lever 19, the engaging piece 18 a engages with the step 16 b at the rear of the rod body, and the rod body 16 is subjected to the urging force of the compression spring 17. Retreat back. As a result, the distal end of the rod body 16 is retracted from the groove and unlocked, so that the bag 2 can be detached from the basket.

A security buzzer can be embedded in the substrate. Although the operation of the security buzzer may be performed manually, for example, a switch that is automatically turned on when an excessive pressing force is applied may be provided at a side end of the receiver. In this case, the security buzzer automatically operates when the vehicle is snatched. Further, the release lever may be provided on the surface of the substrate and manually operated.

Further, in the above-described embodiment, when releasing the lock, the rod main body is retracted by utilizing the step of the rotating shaft, the engagement piece and the rear end of the rod main body. The release mechanism is not necessarily limited to this, and another forcible retraction means may be employed. In addition, the present invention not only prevents a bag placed on a basket or a carrier such as a bicycle from being caught, but also needs to fix the bag, for example, on a shelf surface or a luggage support surface of a transport carrier. Applicable.

[0015]

According to the present invention, while the hook is attached to the bottom of the bag, the lock mechanism is provided on the surface on which the bag is placed, such as the bottom of the basket, and the hook enters the receiver of the lock mechanism. Then, after the operating rod retracts once, it is elastically restored and locked, so that the bag can be automatically locked only by putting the bag in the basket or placing it on the placing surface.

Further, since the bag is fixed on the bottom surface of the bag, the fixed state is difficult to be seen from the outside, and does not promote the willingness of a criminal such as a snatcher. If the security buzzers are arranged side by side in the board to which the lock mechanism is attached, the installation state of the security buzzers can be similarly difficult to be seen from outside.
