Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an auxiliary bed for a large truck.

[Prior Art] Large trucks for long-distance transportation are generally equipped with a bed for taking a nap behind the driver's seat and the passenger seat. However, the width of this bed is limited by the size of the cab, making it impossible for the driver and assistant driver to take a nap at the same time.

In the case of long-distance transportation, it is common for one of two drivers to drive while the other takes a nap, but this may vary depending on road conditions and weather. This is extremely tiring, and even if two people were required to take a nap together, this was not possible with the conventional cab structure.

As disclosed in Utility Model Application No. 54-36219,
Some van-type vehicles have seats that can be expanded into the luggage compartment and used as a sleeping berth, but it is impossible to apply this to the cab of a truck due to space constraints.

[Problems to be solved by the invention] Therefore, in order to solve the above problems, the purpose of the present invention is to provide a system that can be easily attached to a conventional cab so that the driver and assistant driver can take a nap at the same time. The purpose of this invention is to provide an auxiliary bed for large trucks.

[Means for Solving the Problems] In order to achieve the above object, the configuration of the present invention is to attach a pair of locking members to the upper side walls of the cab at the same distance as the armrests provided inside the left and right doors. a retracted state in which hooks provided at both ends of the auxiliary bed are engaged with the locking members, and a retracted state in which the hooks of the auxiliary bed are locked to the armrests of the door and the seat shoes of the driver's seat and the auxiliary seat are engaged with the locking members. It can be changed to a state in which it is placed on the lid of a parcel box placed between parcel boxes.

[Function] If the auxiliary bed 7 stored near the ceiling of the cab is placed on the parcel box 20 on the side of the driver's seat and the hooks 6 at both ends are locked to the armrests 4 on both side doors, the vehicle can be operated. An auxiliary bed for napping is set above the seat and the auxiliary seat.

[Embodiment of the invention] To explain the invention based on an embodiment, as shown in FIG. 1, the floor 2 of the cab of a truck has a central portion 2a configured as a hood that covers the upper part of an engine (not shown). Furthermore, the rear half 2b is further elevated, and the rear half 2b includes a driver's seat 10 consisting of a seat cushion 21 and a seat back 9, and on the opposite side thereof, seat cushions 19, 18 and seat backs 15, 16, respectively. Auxiliary seats 14 and 17 are provided, and a bed is arranged behind these seats. The rear of the bed is defined by a rear wall 29 having a window 28.

A parcel box 20 is disposed in a central portion 2a of a raised floor between a driver's seat 10 and an auxiliary seat 14, and a gear shift lever 12 is disposed between the parcel box 20 and the driver's seat 10. Preferably, the lid 13 of the parcel box 20 is attached to the driver's seat 1.
The seat cushion 21 of the passenger seat 0 and the seat cushions 19 and 18 of the auxiliary seats 14 and 17 are arranged at approximately the same height or slightly lower.

According to the present invention, locking members 5 are fixed to the upper portions of both side walls of the cab at the same intervals as the known armrests 4 attached to the inner walls of the left and right doors 3, and both ends of the auxiliary bed 7 are fixed to the locking members 5. Hooks 6 that engage with the locking members 5 are attached to both ends of the auxiliary bed 7. If the auxiliary bed 7 is pulled up and removed from the locking member 5, it can be engaged with the armrest 4 of the door 3, as shown in FIG.

As shown in FIG. 3, the frame of the auxiliary bed 7 is formed by bending, for example, a pipe material 30 to form a substantially rectangular loop, and connecting it by spanning a plurality of connecting plates 31 over the portion extending parallel to the longitudinal direction. , hooks 6 made of a metal plate or synthetic resin bent into a substantially S-shape are coupled to both ends 30a of the pipe material 30. Then, as shown in FIG. 4, a rectangular thin steel plate or plywood substrate 36 is bonded to the upper side of the pipe material 30, and a thick elastic material 32 such as polyurethane is bonded to the upper side.
The outside of the connecting plate 31 and the elastic material 32 is covered with synthetic leather 33 made of vinyl chloride or the like.

Preferably, the front edge of the auxiliary bed 7 is provided with a protruding edge 7a that projects somewhat upwards from the bed surface 7b to prevent the napper from falling.

Since the present invention is constructed as described above, the auxiliary bed 7 is relatively lightweight and has high strength. When using this, as shown in FIG. The part is supported on the lid 13 of the parcel box 20. Therefore, the weight of the napper on the auxiliary bed 7 is supported by the pair of armrests 4 and the parcel box 30, and when the auxiliary bed 7 is slightly bent, it is also supported by the seat cushions 21, 19, 18. Therefore, the load applied to the door 3 is reduced.

In addition, the strength of door 3 is generally 100 kg for the handle etc.
Since it is designed so that there will be no abnormality even if a certain amount of load is suspended, there is no possibility that the use of the auxiliary bed 7 will cause problems in opening and closing the door 3.

When driving the vehicle, as shown in FIG. It also does not interfere with the use of the bed provided behind the driver's seat. In the stored state shown in FIG. 1, the auxiliary bed 7 can be used as a shelf to store luggage carried by the driver.

[Effects of the invention] Since the present invention is configured as described above, the auxiliary sleeper can be stored near the ceiling behind the driver's seat without making any major changes to the conventional cab, and when it is used, the auxiliary sleeper can be stored near the ceiling behind the driver's seat. Since it is installed above the auxiliary seat using the armrest of the door, it is easy to install, and two drivers can rest using the main berth and auxiliary berth at the same time.
