Description

[Detailed Description of the Invention] The present invention relates to a vehicle with a bed that can freely adjust its inclination angle.

Conventionally, the bed provided at the rear of the cab of large trucks used for long-distance transportation for the driver to nap or rest has a structure that is always kept horizontal.
However, the shape of the bed is generally narrower on the driver's side, so people sleep with their heads on the passenger side.
However, if the vehicle leans to the left or right due to the inclination of the road surface or topography on which the truck is parked, the bed will also lean and the head will be either significantly lower or higher, making it difficult to sleep in an unnatural position. However, there was a drawback that the effects of rest and naps could not be fully achieved.

In order to eliminate the drawbacks of the conventional technology, this invention aims to make one side of the bed adjustable up and down, so that the bed can be held horizontally depending on the slope of the parking place, so that you can always sleep comfortably. It is an idea.

An example of the implementation of the present invention will be explained with reference to the drawings. 1 is a driver's cab of a large truck; 2 is the driver's cab 1;
4 is a floor provided behind the driver's seat and passenger's seat in the vehicle through a space 3 on the floor 2 in the left and right direction (width direction) of the vehicle.
One side 4a of the bed 4 is pivotally supported via a hinge 5 to one side wall 1a in the driver's cab 1 so as to be rotatable in the vertical direction. Reference numeral 6 denotes a step-like bracket in which an upright plate 6a and a bottom plate 6b are connected in an L-shape.A diagonally upward arc-shaped guide hole 6c is bored above the tip of the upright plate 6a. An upright plate 6 connects the front axle 7 and the rear axle 8 to the lower part and the rear part, respectively.
A plurality of concave portions 6a and convex portions 6e are provided in a row so as to protrude in a direction perpendicular to a, and the upper half portion between the front and rear portions is wave-shaped. Reference numeral 9 designates a horizontally rectangular stopper plate, which has a small hole 9a formed in the upper part of the tip at a position corresponding to the guide hole 6c, and a small hole 9a formed in the lower part of the rear part at a position corresponding to the rear shaft 8, which is approximately the same as the guide hole 6c. A long hole 9b is drilled in the diagonal direction, and a window hole 9c communicating in the longitudinal direction is bored between the tip and the rear portion at a position corresponding to the uneven portions 6d and 6e. Washiya 1
2, and screw the nut 13 onto the tip of the rear shaft 8 protruding from the elongated hole 9b, so that the stopper plate 9 overlaps parallel to the upright plate 6a of the bracket 6, making it freely slidable. Attach. Reference numeral 10 denotes an adjustment lever, which has a shaft hole 10b drilled in its lower end corresponding to the front shaft 7, and has a protrusion 10a protruding in the orthogonal direction corresponding to the guide hole 6c. A nut 15 is inserted through the shaft hole 10b and attached to the tip of the front shaft 7.
At the same time, the protrusion 10a is passed through the small hole 9a and the guide hole 6c in order, and the lever 10 is attached to the upright plate 6.
a, it is attached so that it can freely rise and fall around the front shaft 7 and within the range in which the protrusion 10a slides in the guide hole 6c. Reference numeral 11 denotes a supporting frame, in which a horizontal portion 11a, a supporting portion 11b perpendicular to the horizontal portion 11a, and shaft portions 11c provided on the left and right in parallel with the horizontal portion 11a are arranged in a substantially U-shape, and the left and right shafts are connected to each other in a substantially U-shape. A pin hole 11d is bored at the end of the portion 11c. Then, the horizontal portion 11a is inserted in the orthogonal direction into the gap 16 that communicates with the recess 6d of the bracket 6 and the window hole 9c of the stopper plate 9 superimposed on the bracket 6.
1b to the bracket 6 and stopper plate 9,
They are interconnected in a freely undulating manner centering on the horizontal portion 11a. Further, on the floor 2 on the other side 4b of the bed 4, the bracket 6 is arranged in a direction in which its longitudinal direction coincides with the longitudinal direction of the bed 4, and the bottom plate 6b is fixed to the floor 2 with bolts or the like. Further, the left and right shaft portions 11c of the support frame 11 are rotatably supported by the bracket 17, and a pin 18 is locked in the pin hole 11d to prevent the shaft portion 11c from coming off from the bracket 17, and to prevent the left and right shaft portions 11c from coming off from the bracket 17. 17 are fixed to the left and right sides of the bottom surface 4c of the bed 4 with fasteners 19 such as bolts.

Next, to explain the operation of the present invention, when the bed 4 is horizontal as shown by the solid line in Fig. 3, the lever 10
The support frame 11 is tilted and supports the bed 4.
The horizontal portion 11a is located in the central recess 6d, and is suppressed by the upper edge 9d of the inner periphery of the window hole 9c of the stopper plate 9, preventing movement to other recesses 6d. When the inclined lever 10 is raised using the front shaft 7 as a fulcrum, the projection 10a is simultaneously slid upward along the guide hole 6c, and accordingly, the stopper plate having the projection 10a passed through the small hole 9a. The tip of 9 is pushed up, and the rear shaft 8 supporting the rear part is inserted into the elongated hole 9b.
Since it is loosely fitted in the slot 9b, the rear part is also displaced upward within the sliding range of the elongated hole 9b, and the stopper plate 9 rises together with the window hole 9c while remaining parallel to the upper edge 9d of the window hole 9c.
The distance l between the top portion 6f of the convex portion 6e of the bracket 6 is wide enough to allow the horizontal portion 11a of the support frame 11 to pass through. In this state, branch 11b of support frame 11
While holding and lifting the bed 4 together with the shaft part 11c.
It rotates forward (to the left in the figure) centering on the horizontal part 11.
When the shaft 11c passes between the upper edge 9d of the window hole 9c and the top 6f of the convex portion 6e and moves to the forward (left in the figure) concave portion 6d, the shaft portion 11c is supported by the bottom surface 4c of the bed 4 via the bracket 17. Therefore, support frame 1
1 increases the inclination angle or stands upright to push up the other side 4b of the bed 4, and the bed 4
It rotates upwards around the center and tilts.

Further, with the lever 10 in the upright position, while rotating the branch 11b rearward (to the right in the figure) about the shaft 11c, the horizontal part 11a is moved into the window hole 9.
When it passes between the upper edge 9d of c and the top 6f of the convex part 6e and moves to the rear (right side in the figure) concave part 6d, the inclination angle of the branch 11b becomes small, and the other side 4b of the bed 4 is caused by its own weight. The descending bed 4 rotates downward around the hinge 5 and tilts.

After selecting one of these inclination states, when the lever 10 is tilted around the front shaft 7, the protrusion 10a slides downward along the guide hole 6c, and at the same time, the stopper plate 9 also descends, opening the window hole 9c. The upper edge 9d also descends and the distance l between it and the top 6f narrows, making it impossible for the horizontal part 11a of the support frame 11 to pass through and being closed in the fitted recess 6d, so that the horizontal part 11a is There is no transition to the recess 6d.

Therefore, according to the present invention, depending on the inclination condition in the width direction of the vehicle at the parking place, the lever is raised or lowered to change the inclination condition of the bed together with the support frame upward or downward, contrary to the inclination of the parking road surface. The bed can be adjusted to keep the bed level for the user, allowing the user to take a nap or rest comfortably.The user can adjust the inclination angle as needed, and when the lever is pushed down, the horizontal part of the support frame can be moved to another position. Since the bed cannot move into the recessed part of the bed, the support frame can be maintained in an upright or tilted state, and at the same time, the bed can be firmly supported in any of the horizontal, upwardly tilted, and downwardly tilted states, and even when the user's weight is applied during use. It is stable and can withstand long-term use without changing its tilt or swinging, and its structure is simple and easy to operate.
Furthermore, this mechanism is applicable not only to trucks but also to the installation of beds in various vehicles such as wagons, light vans, and camping cars.
