Description

[0001] The present invention relates to a load and / or person handling device.

[0002] It relates in particular to a load and / or person handling device comprising a self-propelled chassis, said to be rolling, equipped with front and rear wheels for its movement on the ground, a load and / or person handling system carried by said chassis, at least one lighting device and a drive control for the movement of the self-propelled chassis, which can be positioned at a distance from the chassis, the self-propelled chassis, which extends longitudinally from the front to the rear of the chassis, comprising on at least one of its lateral sides, taken with respect to the front / rear direction of the chassis, at least one technical compartment and a closing cover for said technical compartment mounted movable between an open position and a closed position.

[0003] A load and / or personnel handling device equipped with a technical compartment and lighting equipment is known, as illustrated in US documents 2018 / 265340 and 2018 / 362313. Such a lighting device can be fitted to the basket of a lifting platform, as illustrated in US document 2013 / 187785. Due to their cost, the operating hours of these devices are increasing, and it is now common to use such handling equipment at night. The difficulty for an operator lies in controlling such a device while in motion at night, particularly when the device is controlled from a remote control located away from the chassis.

[0004] US document 2018 / 265340 A1 therefore discloses a handling device according to the preamble of claim 1.

[0005] One aim of the invention is to provide a handling device of the aforementioned type whose design allows optimal use of the device, particularly at night or when climatic conditions reduce visibility.

[0006] To this end, the invention relates to a load and / or person handling device, said device comprising a self-propelled chassis, said rolling chassis, equipped with front and rear wheels for its movement on the ground, a load and / or person handling system carried by said chassis, at least one lighting device and a drive control for the movement of the self-propelled chassis, positionable at a distance from the chassis, the self-propelled chassis, which extends longitudinally from the front to the rear of the chassis, comprising on at least one of its lateral sides, taken with respect to the front / rear direction of the chassis, at least one technical compartment and a closing cover for said technical compartment, movable between an open and a closed position, characterized in that the device or at least one of the lighting devices of the device is mounted on the closing cover of the device or at least one of the technical compartments,and in that said lighting device is configured to, in the closed position of the hood, illuminate a portion of the space located behind the front wheels relative to the front / rear direction of the chassis, and, in the open position, illuminate the interior of the technical compartment.

[0007] The presence and design of a lighting system on the hood facilitate both remote operation of the vehicle's chassis and its maintenance. The lighting system's design, by illuminating the area behind the front wheels when the hood is closed, aids in guiding the rear wheels, particularly when the vehicle needs to be loaded onto a ramp on a transport vehicle. This design also allows access, when the hood is open, to technical components such as actuators typically housed inside the technical compartment without requiring additional lighting.

[0008] According to one embodiment of the invention, the lighting device comprises a strip of light-emitting diodes.

[0009] According to one embodiment of the invention, at least a part of the lighting device is fixed by a tab to said hood.

[0010] According to one embodiment of the invention, the closing hood is, for its mobile mounting between an open position and a closed position, a pivoting hood mounted to pivot about a longitudinal axis extending along the front / rear direction of the chassis.

[0011] According to one embodiment of the invention, in the state positioned at a distance from the chassis, the drive control for moving the self-propelled chassis has at least one configuration in which it is mounted on the load and / or person handling system carried by said chassis.

[0012] According to one embodiment of the invention, the load and / or person handling system carried by said chassis comprises at least one lifting arm coupled at one of its ends to the chassis and carrying, at its opposite end, a basket inside which an operator is able to take a seat, and the drive control for moving the self-propelled chassis has, in the state positioned at a distance from the chassis, at least one configuration in which it is coupled to said basket.

[0013] According to one embodiment of the invention, the drive control for moving the self-propelled chassis is a remote control with a range of action relative to the chassis of at least two meters. Brève description des dessins

[0014] The invention will be better understood upon reading the following description of exemplary embodiments, with reference to the attached drawings in which: [ Fig. 1 ] represents a ¾ front perspective view of a machine according to the invention with the technical compartment hood closed; [ Fig. 2 ] represents a perspective view taken from the front of a machine conforming to the invention with the hood of the technical compartment closed; [ Fig. 3 ] represents a schematic view of the hood and the lighting system associated with the hood being closed; [ Fig. 4 ] represents a ¾ front perspective view of a machine according to the invention with the hood of the technical compartment open; [ Fig. 5 ] represents a perspective view, taken from the front, of a machine conforming to the invention, with the hood of the technical compartment open; [ Fig. 6 ] represents a schematic view of the hood and the lighting device associated with the open state of the hood.

[0015] As mentioned above, the invention relates to a load and / or person handling device 1, which may conform to that shown, for example, in the figure 1 .

[0016] This load and / or person handling device 1 can allow exclusively the handling of loads or exclusively the handling of persons or both, depending on its design.

[0017] This vehicle 1 comprises a rolling chassis 2 with a front and a rear section. The front and rear sections of this chassis are taken with respect to the direction of travel of chassis 2.

[0018] In the examples shown, this chassis 2 is equipped with two front wheels 3 arranged at the front part of the chassis 2 and two rear wheels 4 arranged at the rear part of the chassis 2.

[0019] This chassis 2 is equipped with a drive unit that propels the vehicle by rotating its wheels. This drive unit will not be described, as it is well known to those versed in this field, and its design is of little importance to the present invention.

[0020] The handling equipment 1 also includes a load and / or person handling system 5 carried by the chassis 2.

[0021] In the examples shown, the load and / or person handling system 5 carried by the chassis 2 comprises at least one lifting arm 51 coupled at one end to the chassis 2 and carrying at its opposite end a basket 52 inside which an operator can sit. The presence of a basket allows for the handling of people and, optionally, loads. Alternatively, the basket can be replaced by a bucket, handling forks, or any other accessory that only allows for load handling.

[0022] The lifting arm 51 is a pivoting arm mounted to pivot around a so-called horizontal axis, parallel to the ground support plane of the wheels of the machine when the machine is positioned on a flat horizontal ground.

[0023] The lifting arm 51 is thus mounted mobilely with pivoting between a low position close to the ground and a high position away from the ground.

[0024] The chassis 2 extends longitudinally from the front to the rear of the chassis 2 and the lifting arm 51 extends along this longitudinal axis.

[0025] The drive unit described above can power one or more pumps that assist in the operation of actuators, such as cylinders, to move the lifting arm 51. Again, this operation will not be described here, as it is well known to those versed in this field.

[0026] The vehicle 1 also includes a drive control 6 for moving the self-propelled chassis 2, which can be positioned at a distance from the chassis 2. This control 6 can take the form of a control panel or console, as in the example shown.

[0027] Control devices such as levers, buttons, knobs or others equip such a control 6 and allow in particular, the control of drive in ground movement of the chassis 2 by rotational drive of the wheels.

[0028] This control 6, which allows a remote control of chassis 2 movement from chassis 2, can be positioned in basket 52.

[0029] Indeed, in the state positioned at a distance from chassis 2, the drive control 6 for the movement of the self-propelled chassis 2 can have at least one configuration in which it is mounted on the load and / or person handling system 5 carried by chassis 2.

[0030] Thus, this drive control 6 for moving the self-propelled chassis 2 can, in the state positioned at a distance from the chassis 2, have at least one configuration in which it is coupled to the basket 52.

[0031] This control 6 can also be a remote control operable by a ground operator, as illustrated in the figure 2 . In this embodiment, the drive control 6 for moving the self-propelled chassis can be a remote control with a range of action relative to the chassis 2, preferably at least equal to two meters.

[0032] Chassis 2 can be additionally equipped with a driver's cab inside which an operator can sit.

[0033] Typically, the self-propelled chassis 2 includes, on at least one of its lateral sides 7, that is, the part of the chassis extending from the front to the rear of the chassis 2, at least one technical compartment 8. A technical compartment 8 may be provided on each side 7, as in the example shown, or on only one of the vehicle's lateral sides 7.

[0034] This technical compartment 8 houses, for example, the engine, pumps, or other components. The interior of the technical compartment 8 is accessible via a side opening closed by a cover 9.

[0035] This closing hood 9 is, in the examples shown, a pivoting hood mounted mobile to pivot around an axis XX' called longitudinal, extending along the front / rear direction of the chassis 2 between an open position and a closed position.

[0036] During its pivoting movement from the closed to the open position, this closing cover 9 pivots upwards. An operator then positions themselves under the closing cover 9 to access components located in the technical compartment 8.

[0037] The device 1 also includes one or more lighting devices, at least one of which, shown in 10 in the figures, is mounted on the closing hood 9 of the or at least one, preferably, of each of the technical compartments 8.

[0038] This lighting device 10 is configured to, in the closed position of the hood 9, illuminate a part of the space 11 located behind the front wheels 3 taken with respect to the front / rear direction of the chassis 2 and, in the open position, illuminate the interior of the technical compartment 8.

[0039] In the examples shown, the lighting device 10 comprises a strip of light-emitting diodes. At least part of the lighting device 10 is attached by a tab 12 to the cover 9, as schematically illustrated in the figures 3 And 6 .

[0040] In practice, the operation of such a device 1 is similar to that of a device of the prior art. The presence of a lighting device 10 at the level of the closing hood 9 of the technical compartment 8 allows, in the positioned state of the remote control 6 of the chassis 2, the device 1 to be moved at night, in complete safety, in particular for the purpose of moving the device 1 on an inclined ramp.

[0041] The presence of this lighting device 10 still allows intervention on the machine 1 in the middle of the night, at the level of the one or one of the technical compartments 8, without needing additional lighting to view the inside of said technical compartment 8.
