Description

[Detailed description of the invention] (Field of industrial application) The present invention involves inserting a metal ring attached to the chin strap of a helmet into a hook protruding from a lock case attached to the body of a motorcycle or other vehicle. The present invention relates to a vehicle helmet holder that locks a helmet or the like to prevent a helmet from being removed from a vehicle body.

(Prior Art) A hook locking mechanism for a helmet holder, etc. is disclosed in, for example, Japanese Utility Model Publication No. 53-54020, and has the following configuration. That is, one side of a U-shaped hook protruding from the lock case is pivoted on the lock case, and the tip of the other end of the hook is inserted into a locking hole provided in the lock case. The swinging piece is engaged with a notched groove provided at the tip of the other end of the hook to hold the hook in an unreleasable manner. In this case, as shown in FIG. 6, the rocking piece rotates in conjunction with a rotor directly connected to the inner cylinder of the cylinder lock 7, and engages and disengages from the notch groove.

By the way, in a helmet holder in which the cylinder lock part and the hook locking part are separated and linked together to provide flexibility in mounting arrangement on the vehicle, the swinging piece is attached to the cylinder lock via a connecting member. It is provided integrally in the rotational direction of the rotor that rotates in cooperation with the rotor. In such a structure, the rotor is generally rotatably supported by the lock case via a retaining ring such as an E-ring (see Japanese Utility Model Application No. 48-41691). ).

(Problems to be Solved by the Invention) However, in the structure of the prior art described above, in which the rotor is rotatably supported on the lock case via a retaining ring such as an E-ring, the number of parts increases, and
There is a problem that assembling the rotor is very troublesome.

(Means for Solving the Problems) The present invention aims to solve the above-mentioned problems in the prior art. A U-shaped hook that is pivoted on the case and biased by a spring in the opening direction, and a rotor that is rotatably provided on the lock case and rotates in conjunction with a cylinder lock that is spaced apart on the lock case. and a rocking piece that is integrally provided with the rotor in the rotational direction and is spring-biased in a direction to engage the free end of the hook, the rotor being pivotally supported in the lock case. A shaft hole is provided, and an insertion groove is formed in the shaft hole in connection with the outer radius of the shaft hole, and the rotor is inserted into the insertion groove in the radial direction at the rear end of the rotor and protrudes toward the back side of the lock case. An engaging piece that engages is provided, and the insertion hole is provided outside the rotation range of the engaging piece in a rotor that rotates in conjunction with the operation of the cylinder lock.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

Fig. 1 is a sectional view of Fig. 2, Fig. 2 is a front view of the helmet holder, and Fig. 3 is a - of Fig. 1.
4 is a rear view of the helmet holder, and FIG. 5 is an exploded perspective view of the helmet holder.

In the figure, A is a helmet holder, and 1 is a lock case provided separately from the cylinder lock.

The lock case 1 is provided with a protruding U-shaped hook 2. Here, the hook 2 has one side 2a pivoted to one end 1a of the lock case 1, and is always biased in the opening direction (clockwise in FIG. 1) by the coil spring 6. ing. Further, the lock case 1 is provided with a locking hole 1b substantially in the center thereof, and the other end side tip portion 2b of the hook 2 can be inserted into the locking hole. There is. Further, the lock case 1 has a shaft hole 1d bored near the other end 1c, and a rotor 4, which will be described later, is rotatably supported in the shaft hole 1d.

The rotor 4 has a locking protrusion 4c on its front end 4a.
is provided. On the other hand, the swinging piece 3 has a shaft hole 3c formed in one end 3b thereof, and a cutout groove 3d is formed in connection with the radially outer side of the shaft hole 3c. Thereby, by inserting the rotor 4 into the shaft hole 3c of the swinging piece 3 and engaging the locking protrusion 4c with the notch groove 3d, the swinging piece 3 can be attached to the rotor 4 integrally in the rotational direction. It's like that. Further, at the rear end portion 4b of the rotor 4,
An engagement piece 4d is provided to protrude in the radial direction. On the other hand, an insertion groove 1e is formed in the shaft hole 1d of the lock case 1 so as to be connected to the radially outer side of the shaft hole 1d. Then, when the swinging piece 3 is integrally attached to the rotor 4 as described above and the rotor 4 is inserted into the shaft hole 1d of the lock case 1, the engaging piece 4d of the rotor 4 is inserted into the insertion groove 1e. The lock case 1 is made to protrude from the back side of the lock case 1. Further, a coil spring 5 is wound around the rotor 4, and in a compressed state, one end 5b of the coil spring 5 is engaged with the locking pawl 3e of the swinging piece 3, and the other end 5a is engaged with the locking claw 3e of the lock case 1. They are each hooked onto the claws 1b. This coil spring 5
Due to the urging force, the engaging piece 4d of the rotor 4 rotates from the insertion groove 1e of the lock case 1, and the rotor 4 is locked on the back surface of the lock case 1 and is pivotally supported without falling off (the second figure). In this way, a retaining ring such as an E ring is not required when the rotor 4 is rotatably supported in the lock case 1, so the number of parts can be reduced and the rotor 4 can be easily assembled. be able to. When the rotor 4 is assembled, the swinging piece 3 is moved in the direction in which the other end 3a engages with the other end side tip 2b of the hook 2 due to the biasing force of the coil spring 5 (see FIG. 4). In a normal state, the tip 2b of the other end of the hook 2 faces the locking hole 1b. Therefore, when the hook 2 is brought from the open position (dotted line in Figure 1) to the closed position (solid line in Figure 1), first, the inclined surface 2d (the third ) causes the swinging piece 3 to retreat once against the biasing force of the coil spring 5, and then the coil spring 5
Due to the biasing force, the other end 3a of the swinging piece 3 engages in the cutout groove 2c provided below the inclined surface 2d, so that the hook 2 can be held in a manner that it cannot be opened. Here, the rotor 4 is connected to a cylinder lock inner cylinder (not shown) separate from the lock case 1 via a rod (not shown) inserted into the locking hole 4e. Therefore, when the cylinder lock is operated with a key, the swinging piece 3 swings via the rotor 4, and the engagement between the other end 3a of the swinging piece 3 and the notch groove 2c of the hook 2 is released. , the hook 2 can be opened by the biasing force of the coil spring 6. In addition, within the swinging range of the swinging piece 3 due to the key operation of the cylinder lock, the engaging piece 4d of the rotor 4 is in the lock case 1.
The rotor 4 is set not to rotate up to the insertion groove 1e, thereby preventing the rotor 4 from falling out of the shaft hole 1d of the lock case 1.

(Effects of the invention) The present invention has the above configuration, so that
Since a retaining ring such as an E-ring is not required when the rotor is rotatably supported in the lock case, the number of parts can be reduced and the rotor can be easily assembled. has.
