Description

[Detailed Description of the Invention] (a) Purpose of the Invention (Technical Field of the Invention) The present invention relates to a step device that is attached to the upper bed of a bunk bed provided behind the driver's seat of a large truck or the like.

(Technical background of the invention) Generally, large trucks such as container cars are equipped with a bunk bed for napping behind the driver's seat.

However, since large trucks usually have a bunk bed in the driver's seat, which is not very spacious, the movement of the body when getting in and out of the bed is restricted, forcing the driver into a very awkward posture. .

In other words, when transferring to the lower bed, all you have to do is fold down the seat back of the driver seat or passenger seat and crawl into the lower bed behind you, but when transferring to the upper bed, the height from the driver's seat to the bed is quite high. Not only that, but there isn't much space between the bed and the ceiling, so it's impossible to get into the bed without any recoil, and it's also difficult to put your feet directly on the bed from the seat. As a result, passengers are forced to get in and out of the vehicle in extremely awkward positions, such as using the seatback of the seat as a stepping stone.

(Prior art and its problems) In order to make it easier to get on and off the upper bed of a two-tier vehicle bed, a step or the like is installed at the center of the front end of the upper bed located between the driver seat and the passenger seat. However, if the step is provided in a hanging manner on the upper bed, it will cause a problem in that it will get in the way when transferring to the lower bed.

For this reason, this type of two-tier bed is currently not provided with a step for transferring to the upper bed, and an improvement has been desired.

(Technical Problem of the Invention) A technical problem of the invention is to provide a step device that facilitates getting on and off the upper bed of a two-tiered vehicle bed.

(b) Structure of the invention (technical means of the invention) In order to solve the above-mentioned technical problem, the technical means of the invention is to provide leg rods protruding from the left and right sides of the step body, and to attach the tip of each leg rod to the left and right sides of the step body. A step with a horizontal shaft protruding left and right on the bracket body, and a vertical guide frame in which the horizontal shaft is slidably fitted into the bracket body are provided, and the leg rod is provided on the lower side of the upper part of the guide frame. Consisting of a bracket provided with a support frame, the above-mentioned brackets are attached to the center of the front end face of the upper bed of the double-tiered bed, one on each side at a predetermined interval, and the horizontal axis of the above-mentioned step is attached to the guide frame of both brackets, respectively. It has a structure that allows it to slide freely.

(Operation of technical means) According to the above technical means, the horizontal shaft protruding from the tip of the foot rod of the step can be slid freely on the vertical guide frame of the bracket attached to the center of the front end surface of the upper bed. Because of the fitting and because the supporting frame of the leg rod is provided on the side below the top of the guide frame of the bracket, when the horizontal axis of the leg rod is at the top of the guide frame, the step will be centered on the top of the guide frame. The step can be rotated in a vertical plane, and when you raise or release your hand with the step rotated and standing up, the horizontal axis will fall along the guide frame to the bottom of the guide frame, and the tip of the leg will touch the support frame. It is held between the front end surface of the upper bed.

Therefore, if you tilt the step forward with the horizontal axis positioned at the top of the guide frame, the step will hang down from the front end of the upper bed, and if you position the horizontal axis at the bottom of the guide frame, the step will hang between the support frame and the upper bed. This serves as a frame to prevent the upper bed from falling, which is held upright by the front end surface of the bed.

(c) Effects of the invention As described above, according to the invention, by rotating the step, it is possible to provide a step for the upper bed that does not interfere with the movement of transferring to the lower bed, and it can also be used as a fall prevention frame for the upper bed. There is a dual effect that can be used.

(d) Example of implementation of the idea Next, embodiments of the present invention will be described with reference to the drawings.

1 to 3 show a first embodiment of the present invention, in which FIG. 1 is a partially cutaway front view of a step device for a double bed for a vehicle according to the present invention, and FIG. 2 is a left side view thereof.

The step device for a double bed for a vehicle of the present invention is composed of a step A and a bracket B to which the step A is rotatably attached.

The step A is formed by bending a tube material, has leg rods 2 protruding from the left and right sides of the step body 1, and has a horizontal shaft 3 protruding left and right from the tip of each leg rod 2, so that it can be attached and detached freely. attached.

The bracket B has a vertical guide frame 5 of an appropriate length protruding from the bracket main body 4, and the guide frame 5.
A support frame 6 is provided on the lower side surface of the frame.

The guide frame 5 is formed by two pieces each having a horizontal axis guide of an appropriate length formed therein and facing each other at an interval that allows the leg rod 2 of the step A to slide.

The support frame 6 supports the leg rod 2 when the step A is erected and in use, and it is preferable that the support surface 6' on the upper surface thereof be as wide as possible.

This bracket B and step A are attached to the front end surface center portion 8 of the upper bed C1 of the two-tiered bed C in the following manner.

In other words, the horizontal axis 3 is connected to the horizontal axis guide 7 of the bracket B.
The brackets B and B are attached to the ends of the left and right leg rods 2 and 2, respectively, by slidingly inserted into the upper bed C1.
Fix it with screws etc.

At this time, the bracket B may be attached below the upper surface 9 of the upper bed C1, but as shown in the figure, the bracket B may be attached below the upper surface 9 of the upper bed C1.
It is preferable that the upper part thereof protrudes from the upper surface 9.

From the above, when the horizontal shaft 3 is at the top of the guide frame 5, the step A can be rotated in the vertical plane and can be moved up and down by the length of the horizontal shaft guide 7.

Therefore, when transferring from the seat D to the upper bed C1, by positioning the horizontal shaft 3 at the top of the guide frame 5 and rotating the step A forward, the upper part of the guide frame 5 and the support frame 6 are connected to the leg lever. 2 becomes the supported step, and after moving to the upper bed C1, lift the step A to stand up, and then push down the step A, so that the tip of the leg rod 2 moves to the upper bed C1.
A fall prevention frame A' which is held in a pinched manner by the front end surface of the frame A' and the support frame 6 is obtained.

Also, when step A is not used, step A
It is sufficient to rotate the bed and lay it on the upper bed C1, so that it does not become a hindrance when transferring to the lower bed C2.

FIG. 4 shows a second embodiment of the present invention, in which a guide frame 5 for guiding the horizontal shaft 3, in other words, a horizontal shaft guide 7, is formed in an inverted J shape.

By doing this, when step A is used as a step, there is no need to put a load on the leg rod 2 of step A and the support frame 6 of bracket B, and the weight of step A and bracket B can be reduced. .
