DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nap bed for a vehicle, and more particularly to a nap bed provided in a driver's cab of a large or medium-sized truck.

[0002]

2. Description of the Related Art Conventional nap beds for vehicles include a bed cushion fixed between a driver's seat and a back panel, or a bed cushion mounted on a back panel so as to be able to jump up and down.

[0003] In the case where a bed cushion is fixed between the driver's seat and the back panel, when the width of the bed cushion is increased to improve the livability of the bed, the driver's seat in the driver's cab where space is limited. It is necessary to move the mounting position of the vehicle forward, or to reduce the forward / backward movement stroke of the driver's seat, so that the livability of the driver's seat may be impaired.

On the other hand, in a device in which a bed cushion is attached to a back panel so as to be rotatable up and down,
Since it is necessary to attach the bed cushion to the back panel in a so-called cantilever state, which causes a problem in supporting strength, it has been difficult to provide a wide bed cushion excellent in comfort and comfort.

[0005] Further, as disclosed in Japanese Utility Model Application Laid-Open No. 62-66545, for example, the lower end of a net attached to a roof panel is connected to the front edge of a bed cushion fixed to the upper rear portion of the driver's seat. Some are designed to enhance the character. However, even in this case, if the width of the bed cushion is increased and the upper part of the driver's seat is covered, the livability of the driver's seat deteriorates. There was also a limit in increasing the comfort of the bed by making it wider. In the case where the bed cushion is supported by a cantilever structure only on the back panel side as shown in Japanese Utility Model Laid-Open Publication No. Sho 62-66545, space or cost is sacrificed in order to secure the support strength of the bed cushion. Therefore, there is a problem that it is not practical because it is necessary to enlarge the supporting portion.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and when a bed is not used, the space behind the driver's seat is made sufficiently large to increase the space utilization efficiency. The support structure is simplified by using a bed cushion that supports both ends with excellent support stability and strength.
It is an object of the present invention to provide a nap bed with excellent livability, which can improve the privacy by making the bed space a private room.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is directed to a roof panel above a driver's seat while a rear edge of a bed cushion is attached to a back panel at an upper rear portion of the driver's seat so as to be able to pivot upward. The upper edge of the partition is attached to be able to fold and rotate backward. In addition , a front edge of the bed cushion and a lower edge of the partition are connected via a flexible joint. The vertical distance from the roof panel to the attachment portion of the bed cushion is set to a dimension corresponding to the hanging length of the partition, and the horizontal distance from the back panel to the attachment portion of the partition is determined by the horizontal distance of the bed cushion. Set to a dimension equivalent to the overhang length
It is characterized by having been specified .

[0008]

When the bed is used, the bed cushion is held horizontally. Since the lower edge of the partition is connected to the front edge of the bed cushion via the flexible joint, the front edge of the bed cushion is connected to the roof panel via the partition. In other words, while holding the rear edge of the bed cushion on the back panel,
Since the front edge of the bed cushion is suspended from the roof panel via a partition, the bed cushion is stably supported at both front and rear ends.

Further, since the bed cushion is located in the upper rear part of the driver's seat, it can stably support a wide bed cushion extending above the driver's seat. In addition,
Since the lower edge of the partition is joined to the front edge of the bed cushion, the bed is made into a private room, so that the privacy is improved and the livability is improved.

On the other hand, when the bed is not used, the bed cushion is flipped upward and rotated. Then, the partition connected to the front edge of the bed cushion via the flexible joint is folded back and rotated. Therefore, when the bed cushion is flipped up and rotated, the partition is also automatically folded and pivoted rearward, so that the upper rear portion of the driver's seat is opened and the livability of the driver's seat is increased. If the bed cushion that has been pivoted upward is held at the jumping position by a conventionally known lock mechanism, the partition is also held in a folded state.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a schematic perspective view showing a vehicle nap bed according to the present invention applied to a cab-over type truck, and FIG.
3 is a schematic side view when the bed shown in FIG. 1 is used, and FIG. 3 is a schematic side view when the bed shown in FIG. 1 is not used.

In these figures, a driver's seat 2 and a passenger seat 3 are mounted on a cab 1 of a cab-over type truck. A bed cushion 5 is disposed above a space formed between the driver's seat 2 and the passenger's seat 3 and the back panel 4 of the cab 1, and the rear edge of the bed cushion 5 is rotatable up and down on the back panel 4. It is pivoted.

The bed cushion 5 has a right and left length substantially equal to the inner width of the cab 1 and a front rectangular shape having a front and rear width extending above the driver's seat 2 and the passenger's seat 3. 6 is a bed cushion 5 with a back panel 3
A pivot shaft is connected to the bed cushion 5 so that the bed cushion 5 can be moved upward by a lock mechanism (not shown).
Can be held in a flipped-up state folded along the front surface of the back panel 4.

A lower edge of a partition 8 having an upper edge attached to a roof panel 7 of the cab 1 via a rotating shaft 10 and a front edge of the bed cushion 5 are connected via a flexible joint 9. Note that the partition 8 is a rotating shaft 10.
Folding and pivoting around the center.

The length of the partition 8 is set to a dimension corresponding to the vertical distance from the roof panel 7 to the mounting portion of the bed cushion 5, and the back panel 4
The horizontal distance from to the mounting portion of the partition 8 is set to a dimension corresponding to the overhang length of the bed cushion 5.
Therefore, when the bed cushion 5 is extended and rotated as shown in FIGS. 1 and 2, the partition 8 is held in a substantially vertical state, and as shown in FIG. 5 is flipped up and turned back panel 4
When it is folded and held on the front of the
It is pivoted rearward about 0 and is folded and stored on the lower surface of the roof panel 7.

The partition 8 is made of a material having high rigidity such as a panel material. By providing an entrance 11 near the end of the passenger seat 2, the partition 8 is formed above the bed cushion 5. It enhances the privateness of the space and the function of preventing falling from the bed space, and secures access to the bed space.

In the vehicle napping bed constructed as described above, when using a bed, the bed cushion 5 is pivoted about the pivot shaft 6 as shown in FIGS.
Is extended and rotated, the front edge of the bed cushion 5 is suspended and held by the roof panel 4 via the flexible joint 9, the partition 8 and the rotation shaft 10 to be held in a horizontal state.

As described above, since the load of the bed cushion 5 is dispersed and supported by the back panel 3 and the roof panel 4, the load on the pivot 6 for attaching the bed cushion 5 to the back panel 4 can be reduced. A wide bed cushion 5 extending above the driver's seat 2 can also be stably supported. For this reason, the bed space can be made sufficiently large without impairing the support strength and stability, and the user can easily enter and exit the bed space from the entrance 11 using the passenger seat 3 or the like.

Since the lower edge of the partition 8 is connected to the front edge of the bed cushion 5 via the flexible joint 9, the space above the bed cushion 5
In other words, the bed space is made into a private room, so that the private property is improved and the livability is improved.

When the bed is not used, as shown in FIG. 3, the bed cushion 5 is swung upward about the pivot shaft 6. Then, the lower edge partitioning scheme 8 connected through a flexible joint 9 to the front edge of the bed cushion 5 is moved rearwardly to pivot the said Patesho <br/> down 8 rearward. The partition 8 is also held in a folded state by holding the bed cushion 5 that has been swung up in a jumping position by a conventionally known lock mechanism.

In the above-described storage rotation, the front edge of the bed cushion 5 and the lower edge of the partition 8 once move close to each other and then separate. However, since the two are connected by the flexible joint 9 to absorb the relative movement while maintaining the connected state of the front edge of the bed cushion 5 and the lower edge of the partition 8, the upward rotation of the bed cushion 5 As a result, the partition 8 is smoothly folded and rotated.

Further, the hanging length of the partition 8 is set to a dimension corresponding to the vertical distance from the roof panel 7 to the mounting portion of the bed cushion 5, and the horizontal distance from the back panel 4 to the mounting portion of the partition 8 is set to the bed. The size is set to a size corresponding to the overhang length of the cushion 5. Therefore, when the bed cushion 5 is extended and rotated, the bed cushion 5 is held in a substantially horizontal state, and the partition 8 is held in a substantially vertical position. When the bed cushion 5 is flipped up and pivoted about the pivot shaft 6 to be folded and held on the front surface of the back panel 4, the partition 8 is pivoted rearward about the pivot shaft 10 and the roof panel 7 is rotated. Is folded and stored on the lower surface of the vehicle, so that the storage space of the bed can be reduced and the uncomfortable feeling in the vehicle interior can be eliminated.

FIG. 4 is a side view of a modified example of the flexible joint when the bed is used, and FIG. 5 is a side view of the flexible joint shown in FIG. 4 when the bed is not used. In this modified example, a pin 12 is provided on the front edge side of the bed cushion 5 and a partition 8 is provided.
A long groove 13 is provided on the side surface of the lower edge. And pin 12
Is slidably slidably engaged with the long groove 13 to allow relative movement between the front edge of the bed cushion 5 and the lower edge of the partition 8 using the rotation and movement of the pin 12 in the long groove 13. ing.

In this modification, a recess 14 is provided in the slot 13 for engaging the pin 12 by the gravity of the partition 8 when the partition 8 is folded and rotated by rotating the bed cushion 5 up and down. Thereby, the lock mechanism for holding the bed in the folded state can be omitted,
The specific structure and lock mechanism of such a flexible joint 9 are not limited to the embodiment.

[0025]

As is apparent from the above description, in the vehicle nap bed according to the present invention, the front edge of the bed cushion whose rear edge is rotatably mounted on the back panel and the roof panel are separated by a partition. Therefore, even when a wide-width bed cushion having excellent livability, whose front edge extends above the driver's seat, is provided, the bed cushion can be stably supported. In addition, a partition in which the front edge of the bed cushion is suspended from the roof panel is connected to the roof panel, so that the bed space can be made private and the function of preventing falling can be enhanced, thereby improving the privacy and safety of the nap bed.

Further, since the front edge of the bed cushion and the lower edge of the partition are connected via a flexible joint, if one of the bed cushion and the partition is rotated, the other is also rotated. In addition, the workability of installing or storing the nap bed is improved, and the lock mechanism for storing and holding the nap bed can be simplified.

Further, the bed cushion and the partitions are folded and stored along the inner surfaces of the back panel and the roof panel, so that the effective space of the cab when the bed is not used can be sufficiently increased. For this reason, even if a wide bed cushion is provided to enhance the livability of the nap bed, the livability of the driver's seat or the passenger's seat is not impaired.
