Description

[Detailed Description of the Invention] The present invention relates to a steering bundle folding device for two-wheeled vehicles, three-wheeled vehicles, etc.

Generally, two-wheeled vehicles, three-wheeled vehicles, and the like that are equipped with a rod-shaped steering bundle have a problem that the rod-shaped steering bundle protrudes outward for a long time and occupies a large space during packaging, transportation, storage, etc.

Therefore, there have been proposals in the past to make the rod-shaped steering bundle foldable to make it easier to pack, transport, store, etc. However, all of these have troublesome folding operations and complex structures. The result was unsatisfactory, either because there were some problems, or because the compactness was insufficient.

The main object of the present invention is to provide a novel steering bundle folding device that is easy to fold, has a simple structure, and can be folded compactly.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.A bundle holder 2 is fixed to the upper part of a steering shaft 1 of a motorcycle, and support collars 3, 3 are symmetrically arranged on both left and right sides of this bundle holder 2. is fixed to.

Each support collar 3 protrudes outward from the outer surface of the bundle holder 2, and its outer end surface 3a is inclined inward toward the rear of the vehicle body B, forming an opposing surface of a bracket 7, which will be described later. There is.

Further, in the support collar 3, first and second engagement recesses g41, 4° that are open to the outer end surface 3a are formed with a phase difference of about 90°, and these eleventh and second engagement grooves 41, 4 are formed with a phase difference of about 90°. □An engaging protrusion 1 that protrudes from a bracket 7.7 which will be described later.
2 and 12 are inserted.

The longitudinal axis LL of each support collar 3 is defined by the outer end surface 3a.
The support collar 3 is provided with a shaft hole 5 centered on the longitudinal axis LL, and the small diameter portion of the shaft hole 5 is a screw hole. 5a.

Brackets 7.7 are integrally provided at the base ends of the left and right pair of rod-shaped steering bundles 6.6.

The inner end of the sleeve 8 integrally welded to the center of each bracket 7 is rotatably fitted into the shaft hole 5 of the support collar 3.

A pivot connection shaft 9 having a knob 10 at the outer end and concentric with the support collar 3 is screwed into the shaft hole 5 through the sleeve 8, and by tightening the pivot connection shaft 9, the support collar 3 and the bracket 7 are connected. and are combined together.

The pivot connection shaft 9 is formed to be long so as to protrude outward from the inner end of the support collar 3, and a stopper piece 11 is provided at the end thereof, and this stopper piece 11 is attached to the support collar 3.
The pivot connection shaft 9 can be pulled out outward until it engages with the inner end surface of the shaft.

A wedge-shaped engagement protrusion 12 is provided on a surface of the bracket 7 that faces the outer end surface of the support collar 3, and this engagement protrusion 12 is connected to the first and second engagement protrusions formed on the support collar 3. 2
The pivot connection shaft 9 is selectively engaged with the engagement grooves 4□ and 4°.
A steering handle 6, which is rotatable in the longitudinal direction of the vehicle body, is locked in an extended position where it stands up on the handle holder 2, and a retracted position where it is engaged with the seat S of the rear force of the handle holder 2. The eleventh second engagement recess i
4. , 4□ and the engaging protrusion 12 cooperate to constitute the locking mechanism E of the present invention.

Next, the effects of the embodiments of the present invention will be explained.
3, when the left and right steering knobs 6, 6 are in the extended position, the first engagement grooves 4. of the support collars 3, 3 fixed to the handle holder 2. , the engagement protrusions 12, 12 of the bracket 7.7 fixed to the steering handle 6.6 are engaged with the bracket 7.7 of the support collars 3, 3 through them. The steering knobs 6, 6 are integrally connected by pivot connecting shafts 9, 9 which are screwed onto the collar 3, and the steering knobs 6, 6 are firmly held in the extended or running position.

If you want to fold and store the left and right steering handles 6.6, rotate the knob 10 in the loosening direction and pull out the pivot connection shaft 9 until its stopper piece 11 touches the inner end of the support collar 3. The bracket 7.7 is moved outward together with the steering handle 6, and the engaging protrusions 12, 12 are moved into the first engaging groove 4t.
, 4t, then fold the steering handle 6.6 around the pivot connection shaft 9 in the direction of folding, that is, about 90 degrees toward the rear of the vehicle.
° Rotate and lay it down in the storage position.

As a result, the bracket 7.7, which is integrated with the left and right steering handle 6.6, also rotates, and its engagement protrusions 12, 12 engage the second engagement grooves 4□, 4.7 of the support collar 3.3. Come to a position opposite to.

Here, if the knob 10 is rotated in the tightening direction, the engaging protrusion 12
, 12 are engaged with the second engaging grooves 4□, 42 to integrally connect the support collars 3, 3 and the bracket 7゜7, and the steering handle 6.6 is shown in Figs. It is firmly tied to the storage position shown by the chain line.

By the way, when the pair of left and right steering handles 6.6 are folded to the storage position, the respective vertical axes L-L of the support collars 3, 3 and the pivot connection shaft 9 are inclined forward inward of the vehicle body B. Therefore, the steering handle 6.6 is folded toward the inside of the vehicle body B, and when it is finally stored, it is stored approximately within the projection plane of the motorcycle, as shown in FIG.

When the steering handle 6.6 is in the retracted state, the steering handle 6.6 is placed on the seat S and the driver cannot sit on the seat S. .6, and the motorcycle becomes unable to drive.

Further, in order to rotate the steering handle 6.6 from the retracted position to the extended position and lock it in this position, the operations may be performed in the reverse order.

As described above, according to the present invention, a pair of support collars 3, 3 are fixed to both sides of the handle holder 2 provided on the steering shaft 1, and the left and right steering handles 6 are attached to these support collars 3, 3.
．． The steering handle 6.6 is pivoted by a bracket 7.7 integrally provided at the base end of the steering handle 6. The supporting collars 3, 3 and the brackets 7, 7 are connected to each other so as to be rotatable in the front and rear directions around the support connecting shafts 9, 9, and there are 1. Locking mechanisms E, E capable of locking the steering handle 6.6 in an extended position in which it stands up on the steering wheel holder 2 and in a retracted position in which it is engaged with the seat S at the rear of the handle holder 2; , the steering handle 6.6 in the extended position can be moved around the pivot connection shafts 9 by just 90'.
It can be compactly folded into the storage position simply by turning it backwards and laying it down, so that the folding operation and reassembly operation can be performed efficiently.

Moreover, since the steering handle 6.6 is engaged with the seat S at the rear of the handle holder 2 in the retracted position,
It is possible to prevent the driver from sitting on the seat S and automatically place the vehicle in a state where it cannot run.

In particular, the vertical axis L-L of the pivot connection shafts 9, 9 is
As the steering handles 6, 6 are rotated from the extended position to the retracted position, the free ends of the steering handles 6, 6 can be brought closer to the internal force of the vehicle body B. In the storage position, the facing handles 6, 6 become compact in the left-right direction of the vehicle body B, making it more convenient for packing, transporting, etc.
