Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a vehicle with a foldable front window.
In particular, a front window whose lower end is rotatably attached to the front of the driver's cab and can be folded forward;
a connecting member whose front end is rotatably attached to the upper end of the front window, extends rearward at the upper part of the driver's cab, and is foldable toward the back side of the front window; The front of the roof is composed of a first fixing member provided at an end and a second fixing member provided at the front edge of the roof at the rear of the driver's cab to which the first fixing member is releasably fixed. The present invention relates to a vehicle with a foldable front window, which includes a fixing means for releasably fixing the rear end of the connecting member to the edge.

[Prior art]

Previously, as a vehicle similar to this type of vehicle, there was a vehicle that adopted a roof that covered the upper part of the driver's seat instead of the above-mentioned connecting member.
It is shown in the publication No. In such vehicles, the front window can be folded forward with the roof folded if desired, and in this state, the area above, in front of, and on both sides of the driver's seat is open, giving the driver's seat occupant a sense of freedom. It is.

[Problem that the invention attempts to solve]

By the way, in such vehicles, although consideration has been given to fixing the front window and roof to the bonnet hood when folded and laid down, no consideration has been given to fixing the end portions of these to each other. Therefore, if the roof is subjected to vibrations in the vertical direction while the vehicle is running in this state, there is a risk that the roof will fly off the front window, and there is a risk that both of them will be damaged. Note that even in the type of vehicle with a foldable front window described at the beginning, a similar problem occurs between the front window and the connecting member.

[Means for solving problems]

In order to deal with this problem, the present invention provides a vehicle with a foldable front window of the type described above, in which a portion of the connecting member at the lower end of the front window is placed on the roof front edge side at a portion facing the first fixing member. It is characterized in that the same member as the second fixing member provided in is provided.

[Functions and effects of the idea]

As a result, in the present invention, when the front window and the connecting member are folded and laid down, the ends of both can be releasably fixed.
There is no risk of the connecting member flying off the front window and damaging both of them. In addition, in the present invention, since the same member as the second fixing member provided on the front edge side of the roof is provided at the lower end of the front window, the connecting member serves as the other fixing member constituting the fixing means. There is an advantage that the first fixing member provided at the rear end can also be used.

〔Example〕

Hereinafter, the present invention will be explained based on the drawings. FIGS. 1 and 2 show a part of a vehicle in which the present invention is implemented. In this vehicle, the lower end of a front window 20 is rotatably attached to a cowl 11 provided at the front of a driver's cab R, and this front window 20 is attached to a ponnet hood 12.

Further, as shown in FIGS. 1 to 3, the rear end portion of the connecting bar 31 is removably attached to a substantially central portion of the roll bar 14 via a bolt 34, which is a first fixing member. This bolt 34 is a second fixing member fixed to the roll bar 14. It is screwed onto the fixing nut 34a, and together with the fixing nut 34a constitutes a first fixing means, and can be screwed into and removed from the fixing nut 34a through the openings on both sides of the connecting bar 31. It's summery. This allows the bolt 34 to be fixed with the nut 34a.
If the rear end of the connecting bar 31 is removed from the roll bar 14, the connecting lever 31 can be rotated toward the back side of the front window 20, and the front window 20 can also be rotated forward. In addition, the windshield 2 of the front window 20
1 is provided with a fixing hook 41 which is a component of the lock mechanism 40. As shown in FIGS. 1 and 4, the lock mechanism 40 includes a swinging hook 42 protruding from a portion of the windshield 21 corresponding to the fixing hook 41, and a swinging hook 42 that is exposed to the driver's cab R. Wire 4 connecting to operation knob 43
4. The swinging hook 42 is
It is biased clockwise by a spring (not shown) to stand up, and when pressed from above by the fixing hook 41 of the windshield 21, it swings slightly counterclockwise and engages with the fixing hook 41. Further, when the operating knob 43 is pulled rearward, the swinging hook 42 swings counterclockwise by the action of the inner wire 44a of the wire 44 to release the engagement with the fixed hook 41. An elastic member 45 made of rubber or the like is fixed around the protruding portion of the swinging hook 42, and when the hooks 41 and 42 are disengaged, the front window 20 is moved by the elastic force of the elastic member 45. It instantly floats upward slightly. Further, the bolt 34 at the lower edge of the windshield 21
As shown in FIG. 5, a fixing nut 34b similar to the fixing nut 34a is fixed to a portion corresponding to the fixing nut 34a, and when the connecting bar 31 is rotated toward the back side of the front window 20 and folded, Connecting bar 3
1 is removably attached via a bolt 34. This fixing nut 34b constitutes a second fixing means together with the bolt 34, and the bolt 34 also serves as the first fixing means.

On the other hand, a side roof 32 is removably attached to an opening above the driver's cab R formed on both sides of the connecting bar 31, as shown in FIGS. 6 and 7. A plurality of operating levers 32b each having an annular hook 32a are rotatably attached to a predetermined portion of the lower surface of the side roof 32. In addition, the lower surface of the windshield 21 and the roll bar 14
A plurality of fixing hooks 32c are attached to a portion of the lower surface corresponding to each operating lever 32b, and each annular hook 32a can be engaged and fixed to each fixing hook 32c by operating each operating lever 32b. As a result, the side roof 32
It is mounted liquid-tightly in the upper opening of the driver's cab R, and by operating each operating lever 32b inside the driver's cab R, the engagement between each annular hook 32a and each fixing hook 32c is released, and the side roof 32 is It becomes removable.

In the vehicle configured in this way, if the engagement between each annular hook 32a and each fixed hook 32c is released by operating each operating lever 32b, the side roof 32 can be removed and the connecting bar 31 can be removed as shown in FIG. In addition, if each bolt 34 is removed from each fixing nut 34a in this state, the connecting bar 31 can be rotated toward the back side of the front window 20 and folded as shown in FIG. The front window 20 can be folded forward to open the upper, front, and both sides of the driver's cab R. Therefore, the occupant can enjoy a sufficient sense of freedom. Further, in this vehicle, since the connecting bar 31 also functions as a reinforcing member for the roof portion, safety is high even in the event of an unexpected accident.
In addition, when it is desired to raise the front window 20, the engagement between the fixed hook 41 and the swing hook 42 is released by pulling the operation knob 43 of the lock mechanism 40. For this reason, the front window 2
If the driver's cab R is raised up and then the procedure reverse to the above-mentioned opening operation is adopted, the driver's cab R will be in a sealed state.

Since the end portions are releasably fixed, there is no risk that the connecting bar 31 will fly over and damage both of them when folded and laid down. Further, a fixing nut 34a, which is a second fixing member of the first fixing means, is used as a second fixing member of the second fixing means.
Since it uses the same fixing nut 34b,
The first fixing member of the second fixing means is the first fixing member of the first fixing means. There is an advantage that the bolt 34 can be used also.

In the above embodiment, a narrow connecting bar 31 extending in the front-rear direction at the upper central part of the driver's cab is used as a connecting member, and a pair of left and right side roofs 32 that cover both side openings of this connecting bar 31 are used. Although an example in which this is adopted is shown, in the present invention, a wide connecting plate that covers almost the entire upper part of the driver's cab can also be adopted as the connecting member. In this case, both side roofs 32 described above can be omitted.
