FIG. 1 is a cabin storage state, and FIG. FIG. 3 shows a state in which the lid and the seat are opened, FIG. 3 shows a state in which the wind screen is in a use position, and FIG. 4 shows a cabin formation state.
[0012]
Further, FIG. 5 is a cross-sectional view showing a state in which the wind screen is stored at the stage of FIG. 2, and FIG. 6 is a similar view at the stage of FIG.
[0013]
1 to 4, this motorcycle supports a front wheel 2 and a rear wheel 3 in front of and behind a vehicle body frame 1 provided in the longitudinal direction of the vehicle body.
[0014]
The front fork 4 that supports the front wheel 2 is steered by a handle 5, and the steering shaft portion and the upper portion of the front fork 4 are covered by a leg shield 6 and a front cover 7.
[0015]
A headlamp 8 is attached to the front lower part of the front cover 7, and a front cover lid 10 is attached to the upper part of the front cover 7 via a lid hinge 9 (see FIGS. 5 and 6) so as to be opened and closed.
[0016]
The front cover / lid 10 itself forms a part of the front cover 7 and functions as a lid that can be freely opened and closed with respect to the windscreen storage space 7a (FIG. 3) formed on the back side.
[0017]
Therefore, the lid 10 serving as a front cover is configured such that when the cabin is formed, the upper side is opened to the front of the vehicle body with the lid hinge 9 as the center, and the wind screen 11 housed inside thereof can be pulled out upward.
[0018]
The wind screen 11 is accommodated in the wind screen storage space 7a inside the front cover / lid 10 via the parallel link 12 (FIGS. 1, 2 and 5) and from the front cover / lid 10 for cabin formation. It is movable up and down between use positions (FIGS. 3, 4 and 6) extending upward.
[0019]
The parallel link 12 has a pair of upper and lower links 13 and 14 provided on both sides in the vehicle width direction. One end of each of the links 13 and 14 is connected to the wind screen 11, and the other end is provided in the wind screen storage space 7a. It is connected to the boss 7b (FIG. 3).
[0020]
However, this connection destination may be either the body frame side in the front cover 7 or the front cover lid 10.
[0021]
A reversing spring 15 is stretched between the link 14 and the front cover 7 or the body frame side of this portion, and the reversing spring 15 selectively urges the wind screen 11 to move to either the use position or the storage position. And it functions as a holding spring for fixing at the moving position and holding the state.
[0022]
The vertical movement operation of the wind screen 11 is performed by moving up and down a hand operation lever 16 having one end connected to the link 13 and the other end extending to a position near the hand of the occupant.
[0023]
As clearly shown in FIG. 6, when the wind screen 11 is in its use position, the lower end portion 11a is spaced apart from the upper end portion 10a of the front cover / lid 10 so as to form a gap. A sliding lid 17 is provided.
[0024]
The sliding lid 17 is previously attached to the upper portion of the wind screen 11 so as to simultaneously cover the lower end portion 11a of the wind screen 11 and the upper end portion 10a of the front cover combined lid 10 when the wind screen 11 is in the use position.
[0025]
In addition, it is guided by a guide rail 18 (FIG. 4) formed on the surface of the front cover / lid 10 so as to be slidable in the vertical direction, and appropriate means such as engagement at the vertical sliding completion position ( The position can be fixed by (not shown).
[0026]
At the rear part of the vehicle body frame 1, a large container box 20 and a seat 22 that can open and close its upper opening via a hinge 21 at the front end are supported.
[0027]
An intermediate portion of the handle 5 is covered with a low floor type floor 23 continuing from the leg shield 6, and a rear portion side of the vehicle body frame 1 including the container box 20 is covered with a rear cover 24.
[0028]
The seat 22 can be raised and lowered with the hinge 21 at the front end as a center, and is fixed to the vehicle body side with a seat lock (not shown) in the illustrated lying position.
[0029]
In the vicinity of the rear end portion of the seat 22, a support protrusion 25 is formed to protrude upward from the vehicle body frame 1, and the subcarrier 26 extends rearward from the support protrusion 25.
[0030]
The sub-carrier 26 is a member used as a rear carrier when the cabin is formed, and the surface thereof is a substantially horizontal flat surface having an area capable of supporting an article of a size that is normally carried.
[0031]
One end of a base portion 30 that also serves as a rear carrier is supported at the protruding end of the support protrusion 25 so as to be swingable.
[0032]
The base portion 30 is a member having a sufficient thickness and rigidity of a substantially rectangular shape in a plan view having a flat portion having the same shape as the sub carrier 26 so that it can be used as a rear carrier when the cabin is stored.
[0033]
The base portion 30 is swingable between an upright position (FIG. 4) used when the cabin is formed and a lying position (FIG. 1) used as a rear carrier when the cabin is stored.
[0034]
A base end portion 33 of a pillar body 32 having a substantially long quadrangular ring shape is swingably attached to the swing end 31 of the base portion 30, and the base end portion 33 is fixed to the swing end 31. The rotation is restricted by the screw 34.
[0035]
The other end of the pillar main body 32 forms a roof support portion 35, and when the cabin is shown by a solid line, the length that rotates around the base end 33 side supported by the swing end 31 and reaches below the seat 22 It has become.
[0036]
The roof support portion 35 is fixed to one end of a soft top roof 36 formed of a flexible and waterproof plastic material or the like, and serves as a roof accommodating portion when the cabin is accommodated.
[0037]
A suitable attachment 38 such as a hook is provided on the other end 37 of the roof 36 (FIG. 4), and can be attached to a counterpart member 11c (FIG. 3) such as a hook formed on the upper end 11b of the wind screen 11. Yes.
[0038]
Next, the operation of this embodiment will be described. In the cabin storage state shown in FIG. 1, the wind screen 11 is stored on the back side of the front cover / lid 10 as clearly shown in FIG. 5.
[0039]
At this time, the wind screen 11 is fixed at the storage position by the elasticity of the reversing spring 15 and is maintained in this state.
[0040]
Therefore, when the front cover / lid 10 is fully opened (FIGS. 2 and 5) and the hand control lever 16 is pulled down, the parallel link 12 rotates upward against the reversing spring 15, so that the wind screen 11 moves upward. Move (Fig. 3).
[0041]
When the wind screen 11 moves by a predetermined amount and the reversing spring 15 moves over the dead point to the use position, the wind screen 11 stops moving by the elasticity of the reversing spring 15 and is fixed at the use position. Is retained.
[0042]
Subsequently, the front cover / lid 10 is closed to a position substantially continuous with the wind screen 11 (FIG. 4), the sliding lid 17 is moved upward, and the lower end 11a of the wind screen 11 and the upper end of the front cover / lid 10 are placed. The gap formed between the portions 10a is hidden (FIG. 6).
[0043]
The sliding lid 17 is moved in a state in which the sliding lid 17 is smoothly and positioned by the guide 18, whereby the wind screen 11 shown in FIGS. 4 and 6 is used.
[0044]
Thereafter, as shown in FIG. 4, the roof 36 that has been folded by raising the base portion 30 and the pillar main body portion 32 in advance is spread, the other end 37 is attached with a fixture 38, and the opposite member on the upper end 11 b of the windscreen 11. When attached to 11c (FIG. 3), a cabin with a roof is easily formed above the vehicle body. In addition, what is necessary is just to perform in a reverse procedure to store from this state.
[0045]
Thus, since the wind screen 11 is moved up and down via the parallel link 12 composed of a pair of upper and lower links 13 and 14, the vertical movement distance can be made sufficiently long, and the window as a member for constituting the cabin. The screen 11 can protrude upwards long enough.
[0046]
In addition, the wind screen 11 moves in parallel during the vertical movement, and the inclination thereof does not change irregularly. Therefore, if the front cover / lid 10 is opened by a predetermined angle in advance (each of FIGS. State), the window screen 11 can be easily and quickly moved up and down by one-touch without interfering with other parts, and the operability is improved.
[0047]
In addition, since the hand operating lever 16 is provided, by operating the hand operating lever 16, the wind screen 11 can be moved up and down more easily and quickly by a one-touch type, and the operability is further improved.
[0048]
Further, since the reversing spring 15 is provided on the parallel link 12, the wind screen 11 can be held in a fixed state at the storage position or the use position without using any special fixing means such as a lock. Sticking can be prevented, and the labor and cost for fixing can be reduced.
[0049]
Furthermore, since a part of the front cover 7 is used as an openable / closable front cover lid 10 and the wind screen 11 is housed on the back side thereof, the entire front cover 7 can be made relatively thin.
[0050]
Note that the present invention is not limited to the above-described embodiment, and can be variously modified. For example, the link mechanism only needs to have a pair of link members in the vertical direction, and is always formed using only a pair of link members. In addition, it may be on either the left or right side.
[0051]
Furthermore, instead of the parallel links, the link members can be made unequal in length if necessary so that the wind screen 11 can take a special movement locus.
[0052]
Further, the present invention can be applied not only to a motorcycle but also to a three-wheeled vehicle having a retractable cabin, and can be used for storing a windscreen alone regardless of the retractable cabin.
