Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a ladder installed in the cab of a vehicle such as a truck.

[Prior Art] A ladder is known which is provided on the cab side panel of a truck and whose upper end extends to the top of the cab.
Further, a step device for moving from the cab to the loading platform has been proposed by the present applicant in Japanese Utility Model Application Publication No. 174179/1983.

By the way, truck drivers are forced to stay in the same driving position for long hours every day, which can easily cause stiff shoulders and lower back pain, and driving on expressways with few curves can be unstimulating, making it easy to fall asleep. . In such cases, it is extremely effective to stop for a short period of time and do some light exercise.

In this regard, the applicant of the present application proposed in Utility Model Application No. 13868/1987 a truck which is provided with a handle that hangs from the upper side of the cab and is used as an exercise device.

Although this proposal itself is valid,
A cab side panel suitable for attaching the handle is usually provided with a ladder, which is a nuisance, as described above.

[Object of the invention] Accordingly, an object of the invention is to provide a vehicle cab ladder that can also be used as a hanging exercise device.

[Structure of the invention] According to the invention, in a vehicle cab ladder that is provided on the cab side panel of a truck and whose upper end extends to the upper part of the cab, a ladder extending from the bottom side of the ladder is installed in the middle of the ladder. A hanging rod made of a bar body is provided at a position projecting in the direction, and handles formed on both sides of the hanging rod project further in the longitudinal direction of the vehicle than the handrails of the ladder.

[Operation and effect of the invention] Therefore, the driver is asked to perform a hanging exercise using the hanging bar, that is, the handle of the bar body, but since the handrail width of the ladder is usually narrow, the handle is attached to the vehicle so that the hand can easily grasp it. It is made to protrude in the front-back direction. Moreover, since the hanging rod is provided at a position that projects in the width direction of the vehicle, when the hanging rod is hung, the body does not interfere with the lower part of the ladder. As described above, according to the present invention, since the driver can exercise by hanging in a parking lot or the like as appropriate, the driver can relax his body, prevent stiff shoulders and lower back pain, and avoid falling asleep. As described above, the present invention can provide a ladder that doubles as a hanging exercise device with a simple structure of simply providing a bar body with a handle on the ladder.

[Preferred Embodiment] When carrying out the present invention, in order to make the bar body protrude in the width direction of the vehicle, it is necessary to provide a protruding part or a protruding part formed on the handrail of the ladder, or to fix it to a protruding stay. is preferred.

Further, when implementing the present invention, it is preferable that the bar body is provided so as to be able to be stored on the handrail side of the ladder.

[Examples] Examples of the present invention will be described below with reference to the drawings.

1 to 3, a cab side panel 2 of a cab 1 of a cab-over type truck has a lower end fixed to a tire fender 3 and an upwardly extending upper end fixed to a roof panel 4. A ladder designated by 5 is provided.

The lower half of the handrails 6, 6 of this ladder 5 is close to the cab side panel 2 like a known ladder, and the upper half is located outward from the known ladder indicated by a two-dot chain line, that is, in the width direction of the vehicle. A plurality of steps 7 are provided by connecting the handrails 6, 6. A hanging rod 8, which is a bar body, is provided at the lower corner portions 6a, 6a of the overhanging upper half.

The part of this hanging rod 8 between the handrails 6, 6 also serves as a step 7, and the handles 8a, 8a that protrude from the step 7 in the front and back direction of the vehicle are designed so that the hanging rod can be held comfortably in the hand. formed in length. Therefore, the overhang amount A of the upper half is set to such an extent that when hanging from the hanging rod 8, the body does not come into contact with the lower half of the handrails 6, 6. Note that this protrusion amount A is kept inward from the outer edge of the side mirror 9, which is the maximum width of the vehicle.

The ladder 5 is constructed in this way, and the driver can park the vehicle at the appropriate time, get out of the vehicle, and perform a hanging exercise by grasping the handles 8a, 8a to relax the body and prevent stiff shoulders and lower back pain, as well as to prevent falling asleep. I can do it.

4 and 5 show another embodiment of the present invention, in which protrusions 11a, 11a with an overhang amount A are formed in the middle of the handrails 11, 11 of the ladder 10, and a hanging rod 8 is attached to the protrusions. This is an example. This embodiment also has the same effects as the embodiment shown in FIG.

6 and 7 also show another embodiment of the present invention, in which a stay with an overhang amount A is placed in the middle of the ladder 12.
This is an example in which a hanging rod 8 is attached via 3 and 13. This embodiment also has the same effects as the embodiment shown in FIG.

FIG. 8 also shows another embodiment of the invention, with ladder 1
Arm 1 with overhang amount A is placed on step 7 in the middle of 4.
6, 16 is pivoted at one end, and a rod 8 is suspended from the other end.
At the same time, one end of the links 17, 17 having elongated holes 17a is pivotally connected to the elongated holes 17a, 17.
Insert step 7a one step above through a, and attach handrail 1
This is an example in which clamps 18, 18 for locking links 17, 17 are provided on 5, 15. In this embodiment, the hanging rod 8 rotates in the direction of arrow a when in use, and rotates in the direction of arrow b when not in use, and the handrail 1
It can be stored on the 5 and 15 sides and fixed with clamps 18 and 18.

FIG. 9 also shows another embodiment of the invention, with ladder 1
Lever 21, 21 with an overhang amount A is pivotally attached to the step 7 part in the middle of the handrail 20, 20 of 9,
A stopper plate 23 connects one end of the lever to attach a hanging rod 8, a return spring 22 is stretched between the other end and the handrail, and locks the lever 21 to the handrail in a horizontal position. This is an example in which 23 is fixedly installed. In the figure, reference numerals 24 and 24 indicate rubber grips attached to the handles of the hanging rod 8. In this embodiment, when the hanging rod 8 is used, it is rotated in the direction of the arrow a to stop the stopper plate 2.
3 and 23, and when not in use, it can be rotated in the direction of arrow b by the return spring 22 and automatically stored on the side of the handrails 20 and 20.

FIG. 10 also shows another embodiment of the present invention, in which one end of the links 27, 27 is pivotally connected to the step 7 in the middle of the handrails 26, 26 of the ladder 25, a hanging bar 8 is attached to the other end, and an overhang is provided. One end of the links 28, 28 of the amount A is pivotally connected, and the other end is guided in guide grooves 30, 30 formed by bars 29, 29 in the handrails 26, 26, and between the hanging rod 8 and the handrails 26, 26. return spring 2
This is an example in which 2 and 22 were adjusted. In this example,
When using the hanging rod 8, pull out the link 28,
One end of 28 is fixed horizontally at the lower end of guide grooves 30, 30, and return springs 22, 2 are fixed when not in use.
2, it can be automatically stored on the side of the handrails 26, 26.

[Summary] As explained above, according to the present invention, by holding the handle of a hanging bar provided on a ladder and performing a hanging exercise, it is possible to prevent stiff shoulders and lower back pain, and to prevent falling asleep.
