The present invention relates to a load-handling or person-handling vehicle.
It relates in particular to a load-handling or person-handling vehicle comprising at least:
Such a vehicle is known, as illustrated for example by the patent EP 3 287 413 or the patent US 2021/276845. Manufacturers of such vehicles are in search of solutions which offer great versatility of the vehicle without adversely affecting its compactness in particular in terms of height.
To this end, the subject of the invention is a load-handling or person-handling vehicle comprising at least:
According to one embodiment of the invention, there being two driver stations in at least two parts, the lower part, secured to the chassis, of one of said driver stations is disposed along a lateral side of the chassis and the lower part, secured to the chassis, of the other of said driver stations is disposed along the opposite lateral side of the chassis of the vehicle, and the upper part of one of said driver stations and the upper part of the other of said driver stations are common and form one and the same upper part configured to cooperate with the one or the other of the lower parts depending on the angular position of the turntable. The upper part common to the driver stations is configured to, in a first angular position of the turntable in which the pivoting arm extends from its pivoting connection to the turntable toward the first part of the chassis, cooperate with one of the lower parts to form a first driver station facing the first part of the chassis, and to, in a second angular position of the turntable in which the pivoting arm extends from its pivoting connection to the turntable toward the second part of the chassis, cooperate with the other of the lower parts to form a second driver station facing the second part of the chassis. This arrangement makes it possible to have two driver stations, one for each direction of movement of the vehicle, depending on the orientation of the turntable without significantly increasing the cost of the vehicle. The first and second positions of the turntable are generally offset by 180° to within plus or minus 20°.
According to one embodiment of the invention, the lower part of the or of at least one, preferably of each of the driver stations in at least two parts comprises a floor, and the upper part a backrest. Preferably, the or at least one of the driver stations in at least two parts comprises a seat pan. Said seat pan is preferably disposed on the upper part of said driver station.
According to one embodiment of the invention, the or at least one, preferably each of the driver stations in at least two parts has what is referred to as an operational configuration in which the upper part is disposed above, and at least partially vertically with respect to, the lower part of said driver station. In this operational configuration, an operator is able to take up position in the driver station. In this operational configuration, the upper part and the lower part form between them a control cabin.
According to one embodiment of the invention, the vehicle comprises at least one system for detecting the operational configuration of the driver station. The presence of a system for detecting the operational configuration of the driver station for the or each driver station in at least two parts makes it possible to notify the operator that the operational configuration has been reached. The operator can then command that the rotation of the turntable be blocked with the driver station in the operational configuration.
According to one embodiment of the invention, the system for detecting the operational configuration of the driver station comprises an inductive sensor and at least one metallic component, the inductive sensor and the metallic component being fitted, without preference, the one to the turntable and the other to the chassis.
According to one embodiment of the invention, the vehicle comprises at least one member for locking the upper part of the or of at least one of the driver stations in the operational configuration. According to one embodiment of the invention, said locking member is formed by a locking finger. This locking finger is borne by the lower or, respectively, upper part of the driver station and is mounted so as to be able to move between an inactive position and an active position in which it is inserted in a recess provided in the upper or, respectively, lower part of the driver station.
Preferably, the locking finger and the associated recess form a tapered push-fit.
Preferably, the locking member forms, in cooperation with the associated recess, a stop configured to prevent an inclination of the upper part of the driver station toward the first or the second part of the chassis forming the front of the chassis.
The vehicle comprises at least one control for the passage of said locking member from one position to the other. This control is actuatable by the operator when the operational configuration of the driver station to be locked is detected.
According to one embodiment of the invention, the vehicle comprises, for the or each driver station in at least two parts, at least one presence sensor in said driver station. The presence of such a presence sensor makes it possible to modify, for example, the control laws of the vehicle when the operator is present in the or one of the driver stations in at least two parts. Under these conditions, it is thus possible, for example, to increase the maximum movement speed able to be reached by the vehicle.
According to one embodiment of the invention, the or at least one of the members for controlling the members for driving the movement of the vehicle along the ground and the or one of the systems for controlling the handling system are integrated into a control console. The vehicle may, without preference, comprise one or more control consoles.
According to one embodiment of the invention, the control console can be removably coupled to at least one of the upper or lower parts of the or of at least one of the driver stations in at least two parts, and the system for controlling the handling system in the control console is, in the state decoupled from the driver station, able to form at least that system for controlling the handling system which is configured to allow said handling system of the vehicle to be controlled outside of the driver station or stations of the vehicle. This control console can also be used in a basket of the handling system when the free end of the pivoting arm of the handling system is fitted with such a basket.
According to one embodiment of the invention, the members for driving the movement of the vehicle along the ground are wheels, at least one of which is coupled to a drive system for driving said wheel in rotation.
According to one embodiment of the invention, the upper part of the or of at least one, preferably of each of the driver stations in at least two parts which comprises a backrest also comprises a seat pan forming a seat.
Preferably, this seat pan forming a seat is disposed at the base of the backrest.
According to one embodiment of the invention, at least the backrest is mounted so as to be able to pivot about a pivot axis, referred to as horizontal, extending transversely with respect to the forward/rearward direction of the chassis.
The backrest is mounted so as to be able to pivot between an upright position in which the operator can take up position on the seat pan and a lying-flat position. The pivoting of the backrest prevents access to the driver station when the backrest is pivotably moved toward the first or the second part of the chassis forming the front of said chassis and corresponding to the lying-flat position of the backrest.
According to one embodiment of the invention, the vehicle comprises at least one sensor for detecting the position of the backrest.
The control unit of the vehicle is configured to block the rotation of the turntable when the backrest is in the upright position and permit the rotation of the turntable when the backrest is in the lying-flat position.
The invention will be clearly understood on reading the following description of exemplary embodiments, with reference to the appended drawings, in which:
As mentioned above, the invention relates to a load-handling or person-handling vehicle 1.
This vehicle 1 comprises a mobile chassis 2 fitted with members 3 for driving the movement of the chassis 2 along the ground. In the examples shown, the members 3 for driving the movement of the chassis 2 along the ground are wheels, but could be formed by caterpillar tracks in an equivalent manner. There may be three or four of these wheels, as in the example shown.
The chassis 2 is fitted with a drive system 24 for driving at least one of the wheels in rotation.
The vehicle 1 may be a vehicle with two or four driving wheels, and the drive system 24 may be a hydraulic or thermal or electrical system, without departing from the scope of the invention.
Such a drive system will not be described in more detail because it is well known to those skilled in this art.
The chassis 2 has a longitudinal axis, a first part 4 and a second part 5 constituting the transverse ends of the chassis 2. Depending on the direction of movement of the chassis 2, the first part 4 forms the front of the chassis 2 and the second part 5 the rear of the chassis 2, or vice versa.
This first part and this second part are connected to one another by the two lateral sides 6 or flanks of the chassis 2.
The vehicle 1 also comprises a load-handling and/or person-handling system 7 borne by the chassis 2. This handling system 7 comprises a rotary turntable 8. The rotary turntable 8 is mounted so as to be able to rotate about an axis of rotation, referred to as vertical, extending vertically in the state when the vehicle is positioned on a horizontal flat surface. The turntable 8 is topped by a pivoting arm 9 mounted so as to be able to pivot on the turntable 8 about an axis, referred to as horizontal, orthogonal to the vertical axis of rotation of the turntable 8 for movement of the arm 9 between a lowered position and a raised position.
The pivoting connection between the turntable 8 and the arm 9 is shown at 10 in the figures.
The free end of the pivoting arm 9, opposite the end coupled to the turntable 8, may be fitted with a load-handling accessory or tool, such as a bucket or a fork, as shown for the handling of a load.
This free end of the pivoting arm 9 may also be fitted with a basket for lifting a person.
The vehicle 1 also comprises at least one driver station 11 borne by the chassis 2 of the vehicle. An operator is able to take up position inside the or each driver station borne by the chassis 2 of the vehicle. Each driver station therefore delimits a location for receiving an operator. Thus the basket, when it is present, can constitute a driver station of the vehicle.
Such a driver station may be borne directly or indirectly by the vehicle 1. Thus, in the case of a driver station formed of a basket, the chassis bears the turntable 8, the turntable in turn bears the arm 9 which in turn bears the basket and therefore a driver station.
The vehicle 1 also comprises at least one member 15 for controlling the members for driving the movement of the chassis 2 along the ground. This control member 15, such as a pivoting lever, also called joystick, makes it possible to control the drive system 24 which in turn allows the wheels to be driven in rotation.
This control member 15 is able to be positioned in at least one of the driver stations.
The vehicle 1 also comprises at least one system 12 for controlling the handling system 7. The or at least one of the control systems 12 is configured to allow the handling system of the vehicle to be controlled at least outside of the driver station or stations of the vehicle.
Thus, it is possible for an operator positioned alongside the vehicle 1 to control the handling system 7 using the or one of the control systems 12.
Again, the or one of the control systems 12 may be in the form of a pivoting lever, possibly fitted with buttons or other control members.
The actuation of the lever or of the control members borne by the lever makes it possible to control the pivoting movement of the arm, the driving of the turntable in rotation, the extension of the arm when the arm is a telescopic arm and possibly the movement of the accessory or tool borne at the end of the arm.
Again, such a control system will not be described in detail because it is well known to those skilled in this art.
In the examples shown, the member 15 for controlling the members 3 for driving the movement of the vehicle along the ground and the system 12 for controlling the handling system 7 are integrated into a control console 121.
The vehicle may comprise a single control console or a number of control consoles. In the case of a plurality of control consoles, at least some of the control consoles may be permanently installed in the driver station or stations.
In the examples shown, the control console 121 is the only one. This control console 121 may be accessible to the operator from outside the vehicle as illustrated in
Such a control console 121 may also be disposed in a driver station 11 of the vehicle.
As mentioned above, when such a control console 121 is disposed in a driver station 11 of the vehicle, it may be installed permanently or removably in said driver station 11.
The vehicle 1 may also comprise control consoles, with some of them only incorporating the function of controlling the handling system. This may be the case when the vehicle is fitted with a basket and this basket is fitted with a control console and the control of the movement of the vehicle along the ground is not permitted from said basket.
The example shown illustrates the case of a vehicle comprising a single control console mounted removably in the driver stations. The zone where the control console 121 is coupled to a driver station is shown at 23 in the figures.
In a manner which is characteristic of the invention, the or at least one of the driver stations 11 of the vehicle is in at least two parts, and the or each driver station 11 in at least two parts comprises at least a lower part 13 secured to the chassis 2 and disposed along a lateral side 6 of the chassis 2 and an upper part 14 that moves as one with the turntable 8. Thus, this upper part 14 moves in parallel with the rotation of the turntable 8.
The load-handling vehicle 1 may be fitted with a single driver station in at least two parts or several driver stations 11 in at least two parts as in the example shown in
Specifically, in
The upper part 14 of one of the driver stations 11 and the upper part 14 of the other of the driver stations are common and form one and the same upper part 14 configured to cooperate with the one or the other of the lower parts 13 depending on the angular position of the turntable 8.
Thus, the upper part 14 of one of the driver stations 11 is configured to, in a first angular position of the turntable 8 in which the pivoting arm 9 extends from its pivoting connection to the turntable 8 toward the first part 4 of the chassis 2, cooperate with one of the lower parts 13 to form a first driver station facing the first part 4 of the chassis 2, as illustrated in
This upper part 14 is also configured to, in a second angular position of the turntable 8 in which the pivoting arm 9 extends from its pivoting connection to the turntable 8 toward the second part 5 of the chassis 2, cooperate with the other of the lower parts 13 to form a second driver station facing the second part 5 of the chassis 2, as illustrated in
The pivoting arm is offset by 180° between the first and second positions of the turntable. The operator can thus see the end of the pivoting arm in the two directions of movement of the vehicle.
Of course, the member or members for controlling the members for driving the movement of the vehicle along the ground are adapted during operation depending on the driver station that they are fitted to. Likewise, the assembly formed by the turntable and the upper part of the or of at least one of the driver stations is configured to move in a space extending above the lower part of the driver station or stations in at least two parts so as to not collide with the lower part or parts during the rotation of the turntable.
Such a driver station 11 in at least two parts can have a large number of forms. Generally, the lower part 13 of the or of at least one, in this instance of each of the driver stations 11 in at least two parts comprises a floor 16, whereas the upper part 14 of said driver station comprises a backrest 17 against which the operator can rest with their back.
The or each of the driver stations 11 in at least two parts has what is referred to as an operational configuration in which the upper part 14 is disposed above, and at least partially vertically with respect to, the lower part 13 of said driver station 11. It is in this operational configuration that the operator can take up position inside the driver station. In this operational configuration, the upper and lower parts form between them a control cabin.
The upper part 14 of the driver station 11 forms the upper part of the cabin. This upper part delimits an enclosure topped by a roof. The inside of the enclosure is accessible through a door or a gate provided in said enclosure. It should be noted that the roof and part of the rear face of the or of at least one of the driver stations may move as one and form a protective assembly. This assembly may have a first configuration, referred to as active configuration, for protecting the location for receiving an operator in which the roof is in a raised position, and a second configuration in which the roof is in a lowered position. This assembly is mounted so as to be able to pivot about an axis transverse to the longitudinal axis of the chassis corresponding to the forward/rearward direction of the chassis and is configured to pass from the first configuration to the second configuration by pivoting movement toward the first or the second part of the chassis forming the front of the chassis. The vehicle may comprise a mechanism for locking said assembly in each of the first and second configurations. This design allows the assembly forming a system for protecting against rollover or falling objects to simply and quickly pass from the first configuration in which the vehicle can be controlled from the driver station to a second configuration in which the vehicle can be controlled from a location outside of the driver station or stations. The simple pivoting movement of the assembly toward the front allows such a passage from the first to the second configuration. Conversely, the simple pivoting movement of the assembly toward the rear can allow passage from the second configuration to the first configuration. No removal of components is necessary. The presence of an active locking mechanism in the two configurations makes it possible to avoid, in the first configuration, an unintentional pivoting movement of the assembly in the direction for lowering the roof and, in the second configuration, any unintentional movement of said assembly in the direction for raising the roof at the risk of damaging the assembly by passage through zones with low ceiling height. This assembly, which is an assembly mounted by way of a pivoting connection, able to pivot about an axis transverse to the longitudinal axis of the chassis is a rigid assembly. This rigid assembly can be likened to a roll bar. The rigid assembly forms a roll bar substitute.
The floor of the lower part of the driver station extends between the front and rear wheels of the vehicle that are disposed along the same lateral side 6 of the vehicle. This floor forms a platform inside the enclosure, delimited by the upper part.
This floor may be bordered by at least two walls which prevent the operator having taken up position on the floor from being able to touch the wheels of the vehicle.
The driver station may also comprise a seat pan 26 forming a seat. This seat pan 26 is generally disposed at the base of the backrest 17 as illustrated in
The vehicle 1 comprises at least one sensor 28 for detecting the position of the backrest 17. Such a sensor 28, shown in
Inside the driver station, the operator may be in a standing position with their feet resting on the floor and their back resting against the backrest, or in a semi-seated position, when a seat pan 26 is fitted at the base of the backrest.
The control console 121 is preferably configured to be fitted to the upper part 14 of the driver station 11.
Thus, if the vehicle comprises two driver stations 11 with a common upper part 14, the same control console 121 can be used for the two driver stations.
Likewise, the control console 121 may be non-removably installed inside the control station.
In a variant and as in the example shown, the control console can be removably coupled to the upper part of the driver station or stations 11 in at least two parts.
This control console 121 is, in the state decoupled from the driver station 11, able to form at least that system for controlling the handling system 7 which is configured to allow said handling system 7 of the vehicle to be controlled outside of the driver station or stations 11.
A sensor may be provided for detecting the coupling of the control console 121 to the driver station, and its presence inside said driver station.
To improve the vehicle 1, the vehicle 1 comprises, for each driver station in at least two parts, a system 18 for detecting the operational configuration of the driver station 11.
Thus, for example, the system 18 for detecting the operational configuration of the driver station may comprise an inductive sensor 19 and at least one metallic component 20.
The inductive sensor 19 and the metallic component 20 are fitted, without preference, the one to the turntable 8 and the other to the chassis 2.
When the upper part 14 is disposed above, and at least partially vertically with respect to, the lower part 13 of the control station 11, the inductive sensor 19 detects the metallic component 20 and a signal can be sent to a control unit of the vehicle 1. This control unit is in the form of an electronic computer system comprising, for example, a microprocessor and a working memory.
This control unit is configured to, upon reception of a signal from the detection system 18, permits control of rotational locking of the turntable 8 using a locking member which will be described below. It will specifically be appreciated that a rotation of the turntable 8 must be blocked when the driver station 11 in at least two parts is occupied by an operator.
To increase the safety, the vehicle 1 therefore comprises at least one member 21 for locking the upper part 14 of the or of at least one of the driver stations 11 in the operational configuration.
This locking member 21 is preferably formed, as in the example shown, by a locking finger that can be actuated by means of a control in the vehicle. This locking member, borne by the lower part or, respectively, the upper part of the driver station, may therefore be in the form of a finger which is locked in a recess provided in the upper part or, respectively, the lower part of the driver station.
The actuation of this locking member 21 for its passage from the unlocked position to the locked position is controlled by the operator, this locking being permitted when the control unit of the vehicle has received a signal from the detection system notifying that the driver station is positioned in the operational configuration.
Such mechanical locking prevents any misalignment between the upper part and the lower part of the driver station.
In the example shown, the locking finger is borne by the lower part 13 of the driver station and is inserted into a recess provided in the upper part 14 of the driver station. The locking finger and the associated recess form a tapered push-fit. The locking member forms, in cooperation with the associated recess, a stop configured to prevent an inclination of the upper part of the driver station toward the first or the second part of the chassis forming the front of the chassis. The tapered coupling allows the rotation of the upper part to be locked while generating mechanical support. Thus, when the operator is handling a load, the differences in behavior between the upper part and the lower part of the control station are not felt by the operator.
From a driver station in at least two parts, the operator can, from the control console 121 installed in said driver station, control the movement of the vehicle along the ground and the pivoting movement of the arm. In contrast, any rotational movement of the turntable is blocked.
The vehicle also comprises, for the or each driver station 11 in at least two parts, at least one presence sensor 22 in said driver station. This presence sensor 22 notably makes it possible, when no operator is detected in the driver station in at least two parts comprising such a sensor, to once again permit the rotation of the turntable.
In practice, the operation of the vehicle may be as follows: the operator, situated alongside the vehicle, controls, from the control console, the rotation of the turntable 8 to bring the upper part of the or of one of the driver stations into the operational configuration, that is to say at least partially above, and vertically with respect to, the lower part of said driver station.
When this position has been reached, and detected by the detection system 18, the operator can control, from the control console 121, the locking of the upper part by commanding the actuation of the locking member 21.
The control console 121 can then be installed in the driver station 11, when this control console has been removably mounted in the driver station 11. Otherwise, the operator can take up position in the driver station 11 and use the control console 121 positioned in the driver station 11, this control console 121 having been activated by the locking of the locking member.
In the case of a removable control console 121, a sensor makes it possible to detect the coupling of the control console 121 and its positioning inside the driver station 11.
Under these conditions, the vehicle may be controlled in terms of movement from the control console installed in the driver station, and the handling system may also be controlled, with the exception of the rotation of the turntable, which is blocked.
To permit a rotation of the turntable, the locking member 21 must be unlocked. This command is performed by the operator. It is not necessary to perform any presence detection in the driver station or stations in at least two parts and in the case of a removable control console, the control console does not have to be detected in the control station.
It should be noted that similar operation could be obtained with a vehicle fitted with several control consoles, one of which would be mounted permanently, for example on the upper part of the driver station or stations in at least two parts. In this case, the condition of the presence of the control console in the driver station in at least two parts is not examined for permitting or blocking the rotation of the turntable.
