Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a ladder attached to a cab of a vehicle.

[0002]

[Prior art]

 BACKGROUND ART It is known that trucks and other vehicles are provided with a trolley for carrying luggage loaded on a pallet, and the trolley is stored in the pallet or inside the vehicle when the vehicle is running.

[0003]

[Problems to be solved by the device]

 However, in the conventional carts described above, a place for storing the carts in the cargo bed or inside the vehicle is necessary, which may reduce the cargo to be loaded.

Therefore, an object of the present invention is to provide a cab ladder for a vehicle that does not require a special storage space and is detachably formed and can be used as a dolly.

[0005]

[Means for Solving the Problems]

 The present invention relates to a ladder attached to a cab of a vehicle, a first base attached to the cab to lock a lower portion of the ladder, and a second base attached to the cab to lock an upper portion of the ladder. And, the ladder is equipped with removable casters.

[0006]

[Action]

 Therefore, the ladder can be used by removing the ladder from the first and second bases and attaching the casters to the ladder. Since the caster is removed when traveling and the cab is supported by the cab via the first and second bases, there is no need for a space for storing the ladder on the loading platform or the like. In addition, the ladder can be supported by the cab while traveling with the casters attached.

【Example】

 1 to 3 show an embodiment of the present invention.

In FIGS. 1 to 3, reference numeral 1 denotes a cab of a truck having a luggage carrier at a rear part of a vehicle body, and a fender 20 for preventing mud splash from a front wheel (not shown) is provided at a lower end of a side plate 2 forming a side of the cab 1. Is fixed.

A ladder base 4 as a first base that fits and supports the lower end of the ladder 3 is fixed to the upper surface of the fender 20 via a pedestal 42.

As shown in FIG. 2, the ladder 3 has handrails 30 formed of a pipe-shaped member having a U-shaped portion 33 formed by bending the upper end into a U-shape and arranged in parallel at predetermined intervals. At the same time, the handrails 30 and 30 are formed by the step 31 of joining the handrails 30 at a predetermined interval. While the fitting portion 32 of the cylindrical member formed to have a predetermined outer diameter is projected downward from the lower end of the handrail 30, the fitting is also performed from the upper end of the handrail 30 bent downward by the U-shaped portion 33. A fitting portion 34, which is a cylindrical member having a predetermined outer diameter, projects downward in a direction substantially parallel to the joining portion 32.

The ladder base 4 has a handrail 40 formed of a pipe-shaped member that is fitted on the inner periphery with a fitting portion 32 protruding from the lower end of the handrail 30 and that supports the handrail 30 at its upper end surface from the upper surface of the pedestal 42. The handrails 30 and 30 are erected parallel to each other at equal intervals, and the handrails 40 and 40 are joined by arranging a step 41 formed of a pipe-shaped member at a predetermined interval.

At a predetermined position above the side plate 2 of the cab 1, a supporting portion 5 that supports the upper end of the ladder 3 is fixed.

The support portion 5 is a support pipe formed of a pipe-shaped member that is fitted to the outer circumference of the fitting portion 34 that projects downward from the upper end of the handrail 30 and that supports the handrail 30 at the upper end surface. 51 is provided upright in parallel with the handrails 30, 30 at a predetermined position on the side plate 2, and the support pipes 51, 51 are respectively supported by brackets 50, 50 protruding from the side plate 2.

Between the uppermost step 31 forming the ladder 3 and the handrails 30, 30, a reinforcing plate 60 formed of a plate member formed in a substantially triangular shape is fixed and provided on the reinforcing plate 60. The threaded portion of the caster 6 shown in FIG. 3 penetrates the through hole 61, and the caster 6 is fixed to the reinforcing plate 60 by the nut 7.

Similarly, a reinforcing plate 60 formed of a plate-shaped member formed in a substantially triangular shape is also fixed between the lowermost step 31 forming the ladder 3 and the handrails 30, 30. The threaded portion of the caster 6 shown in FIG. 3 is penetrated into the through hole 61 provided in 60, and the caster 6 is fixed to the reinforcing plate 60 by the nut 7.

With the above-mentioned configuration, the operation will be described below.

When the vehicle is running, the lower end of the ladder 3 is fitted to the ladder base 4 and the upper end is fitted to and supported by the supporting portion 5, as shown in FIG. In this state, the ladder 3 can travel without easily falling off the side plate 2 of the cab 1, and while the vehicle is stopped, the occupant can move to the roof of the cab 1 while supporting the weight in step 31. You can

On the other hand, when loading or unloading a luggage onto a loading platform (not shown) at the rear of the vehicle, first, as shown in FIGS. 2 and 3, first, the handrail 30 of the ladder 3 is lifted and the fitting portions 32 and 34 are moved to the handrail 40. And the support pipe 51, and the ladder 3 is removed upward from the ladder base 4 and the support 5.

Next, the threaded portion of the caster 6 is passed through the through holes 61 of the four reinforcing plates 60 provided on the removed ladder 3, while the casters 6 are fixed to the reinforcing plate 60 by the nuts 7. At this time, the caster 6 may be projected on the reinforcing plate 60 by screwing the nut 7 on the U-shaped portion 33 side of the ladder 3. In this state, the ladder 3 can run on a flat surface by the casters 6 provided on the side without the U-shaped portion 33, and the luggage (not shown) is placed on the side where the U-shaped portion 33 of the handrail 30 bends. By pushing 33 or the like, the luggage can be easily transported and labor can be saved.

On the other hand, in order to store the ladder 3, the nut 7 is loosened and the caster 6 is removed from the reinforcing plate 60, and the fitting portions 32 and 34 protruding from the handrail 30 of the ladder 3 are attached to the handrail 41 and the support pipe 51, respectively. When fitted, the ladder 3 is supported by the ladder base portion 4 and the support portion 5 and the traveling can be restarted. The casters 6 and the nuts 7 may be placed inside a vehicle (not shown).

In this way, the casters 6 that can be attached to and detached from the ladder 3 are provided, and the ladder base 4 and the support 5 fixed to the side plate 2 of the cab 1 are detachably supported. When the ladder is needed, the ladder 3 can be used as a dolly by removing the ladder 3 from the side plate 2 and attaching the caster 6, which eliminates the need to store the dolly in the cargo bed of the vehicle or in the vehicle. It is possible to effectively use the cargo bed or the inside of the vehicle.

In the above embodiment, the casters 6 can be attached to the ladder 3 at four places, but the casters 6 may be attached to three places or the like, and the number of the casters 6 to be attached may be changed according to the load to be loaded. good.

Although the caster 6 is fixed to the ladder 3 via the reinforcing plate 60 in the above embodiment, it may be screwed into the handrail 30 or the through hole provided in the step 31, though not shown.

In addition, although the ladder 3 is used as a trolley in the above-described embodiment, although not shown, a removable plate member is provided between steps 31 and 31 to be used as a bed when servicing the vehicle. It can also be used as a dolly for removing and installing spare tires.

[0025]

[Effect of device]

 As described above, according to the present invention, the ladder is provided with removable casters, and the ladder is detachably supported by the first and second bases fixed to the side plate of the cab, so that the occupant or the like carries the load. In this case, the ladder can be effectively used as a trolley, and it is not necessary to secure a storage place for the trolley in the pallet or in the vehicle, and the loading efficiency of the pallet or the like can be improved.
