Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a helmet holding structure for motorcycles and tricycles. Since it is most suitable for a motorcycle mounted in an overhanging manner in the direction, the explanation will be mainly given below by taking a motorcycle with pedals as an example of such a type of motorcycle.

[Conventional technology]

When driving a motorcycle or tricycle, a helmet is worn, and when getting off the vehicle, the helmet forms a hook that can be opened and closed, for example, between the seat bottom plate and the side of the vehicle body frame, and this allows the helmet to be hung and held. is common.

By the way, some motorcycles and tricycles have a seat post that extends upward from the main pipe and a saddle-shaped seat attached to the upper end of the seat post. Since it is not possible to open and close the structure, the above-mentioned conventional structure cannot be adopted.Therefore, as a helmet holding structure for this type of motorcycle, conventionally, for example, a helmet holding structure is attached to a part of the engine's engine which is installed on the side of the front fork. There are helmet hangers that are installed side by side, and the Ibnira Shiranki that doubles as a key to rotate the hook of the helmet hanger.

[Problem that the invention seeks to solve]

However, in the conventional structure in which the ignition key is also used as the ignition key, the hanger is located at a relatively low position, so it is necessary to bend down to operate the hanger, resulting in poor operability. Furthermore, there is a problem in that the helmet protrudes outward in the vehicle width direction when held, and tends to get in the way of other vehicles, especially in crowded bicycle parking lots. In particular, with the recent tightening of the obligation to wear helmets, there is a need for a helmet holding structure that is easy to operate and does not get in the way of other vehicles.

The present invention solves the problems of the conventional structure as described above, and provides a helmet holding structure for motorcycles and tricycles that has good operability and has a small amount of protrusion of the helmet outward in the vehicle width direction. The purpose is

[Means for solving problems]

Therefore, the present invention provides a motorcycle or a tricycle in which a saddle-shaped seat is attached to the upper end of a seat post provided upright on a main vibrator so as to protrude in an overhang shape toward the front or rear of the vehicle. A helmet hanger is disposed on one side, and the helmet is held detachably by the hanger. Here, the helmet hanger may be fixed to the seat bottom plate or a bracket for supporting the seat.

[Effect]

In the helmet holding structure for motorcycles and tricycles according to the present invention, the helmet is held below the overhang of the seat, which is installed at a relatively high place such as the upper end of the seat post, so that the holding position is relatively high. This allows you to put on and take off the helmet without bending your body too much, which improves operability. In addition, the space under the seat overhang, which had not been used effectively in the past, was used as a helmet holding space.
This means that the utilization of dead space has improved accordingly. Furthermore, in the held state, the helmet is located outward in the vehicle width direction, and as a result, the amount of outward protrusion in the vehicle width direction is minimized, so that it hardly gets in the way of other vehicles.

18a is a front brake cable.

A movable tube 20 is inserted into the seat post 5 so as to be slidable up and down, and a buffer spring 21 is provided between the blind plate 20a fixed to the lower end of the tube 20 and the bottom surface of the seat post 5. is inserted, and furthermore, a damper member 22 is arranged on the bottom surface of the seat post 5.

Further, a seat support bracket 23 is fixed by welding to the upper end of the movable tube 20, and a bottom plate 25 of the seat 24 is fixed onto the bracket 23 by embedded bolts 26. Furthermore, a stopper bolt 27 is screwed into the seat post 5, and the tip end of the stopper bolt 27 is inserted into an elongated hole 20b formed in the movable tube 20 and extending in the vertical direction.

The seat 24 is saddle-shaped and protrudes in an overhanging manner in the ff1l direction and rearward with respect to the seat support bracket 23. The seat bottom plate 25 has an approximately inverted U-shape when viewed in cross section, and a helmet hanger 30 is fixed to the center of the front overhang portion of the seat bottom plate 25 in the vehicle width direction with a mounting bolt 31. The boar hanger 30 is substantially hidden in the side edge of the seat bottom plate 25. A hook 33 is rotatably provided in the hanger main body 32 of the helmet hanger 30 and biased in the locking direction, and the hook 33 is fixed to the tip of a rotor 34 that is rotated by the main switch. has been done. Further, a lock par 35 is rotatably supported on the hanger main body 32, and when the lock par 35 is rotated to the lock position, an engagement groove 35a formed at the tip of the lock par 35 engages with the hook 33. configured to engage with.

Next, the effects of this embodiment will be explained.

In the structure of this embodiment, in order to hold the helmet 40 below the seat 24, first insert the upgrade I-36 into the key hole of the rotor 34 of the helmet hanger 30, and rotate it in the unlocking direction. . Then, the locking member 35 of the 1st hanger 30 disengages from the hook 33, and the 11th! l It rotates downward due to its own weight, as shown by the two-dot chain line. Therefore, the locking ring 40a attached to the chin strap of the helmet 40 is hooked to the locking member 35, and
In this state, the lock par 35 is rotated upward.

Then, the hook 33 engages with the engagement groove 35a at the tip of the lock par 35. If the ignition key 36 is removed in this state, the helmet 40 is held at a relatively high location below the front overhang of the seat 24 and at the center in the vehicle width direction.

In this way, in the structure of this embodiment, the helmet hanger 30
is located at a relatively high location in the overhang part of the seat 24, so operations such as inserting and removing the ignition key 36, and hooking the locking ring 40a to the locking member 35 can be performed without bending too much. It is easy to operate. Furthermore, the helmet hanger 30 is hidden within the seat 24, so that the helmet hanger 30 does not damage the appearance and has the effect of suppressing theft. Furthermore, the space below the overhang of the seat 24 is a dead space that has not been used conventionally, and this embodiment improves the utilization of this dead space.

Further, when the movable tube 20 is inserted into the seat post 5 so as to be movable up and down to support the seat 24 in a buffered state, it is necessary to prevent the seat 24 from rotating in a horizontal plane. Therefore, in the past, for example, a positioning pin was inserted into the seatbost, fixed by welding, etc., and the tip of this pin was held in the slit of the movable tube, but with this conventional structure, the slit was extended to the lower end of the movable tube. As a result, there was a problem in that the strength of the movable tube was reduced. On the other hand, in this embodiment, the stopper bolt 27
Since this is screwed onto the seat post 5 and inserted into the long hole 20b of the movable tube 20, this long hole 20b
It is not necessary to extend to the lower end as in the conventional case, and the strength of the movable tube 20 can be maintained accordingly.

In addition, when wiring operation cables etc. along the main pipe, conventionally, for example, an insertion hole was drilled in the main pipe and the wiring was routed inside the vibrator, but the strength was reduced due to stress concentration in the insertion hole, or There were problems such as poor wiring workability. On the other hand, in this embodiment, the housing recess 3a is formed in the main pipe 3, and the operating cable etc. are routed within the cough recess 3a, so that the above-mentioned problems of reduced strength and deterioration of workability can be solved.

Furthermore, conventionally, motorcycles with pedals and the like are equipped with a cheno cover to prevent the transmission chain from getting caught, a protector to prevent the rear wheel from getting caught, etc., but in this embodiment,
A side cover 17 is provided, and this cover 17 has a shape that has the function of preventing the transmission chain from getting caught, the function of preventing the rear wheel from getting caught, and the function of protecting the vehicle components. The parts can be used interchangeably, which has the effect of reducing the number of parts and the number of erection steps, as well as providing a novel appearance that has never been seen before.

In the above embodiment, the helmet 40 was held on the front side of the seat 24, but as shown by two points MvA in FIG.
This may be held on the rear side.Also, although the above embodiment describes a motorcycle with pedals, the scope of application of the present invention is not limited to such a motorcycle, and in short, the seat As long as the seat is attached to the upper end of the post in an overhanging manner, it can be applied to any motorcycle, and even tricycles with one front wheel and two rear wheels.

〔Effect of the invention〕

As described above, according to the helmet holding structure for motorcycles and tricycles according to the present invention, a helmet is held under the front or rear overhang of the saddle-shaped seat attached to the seat post in an overhang shape. This has the effect of improving operability since the helmet hanger is located at a relatively high place, and also has the effect of making effective use of dead space, and also reduces the amount of protrusion of the helmet outward in the vehicle width direction. It also has the effect of minimizing interference with other vehicles.
