Abstract

The present invention relates to an all-terrain handling device with a driver on feet comprising 3 wheels, 2 of which are driving wheels and arranged on a "U" -shaped frame on either side of the load transported; This has the advantage of being able to take loads placed on the ground but above all of using almost the entire weight of the load transported to provide the necessary adhesion to the driving wheels. The third wheel is used to steer the truck in its evolution by means of a driving drawbar. The drive components are connected to the frame by a suitable support located substantially above the steering wheel and controlled from the steering drawbar. A common attachment system for tools located in the bottom of the "U", in front of the drive components and directed away, allows the mounting of a wide variety of handling tools such as pallet or fork lifting forks. work tools such as jackhammer support for example. The use of this device does not require any special knowledge or training. This device is fully justified as a handling aid on artisanal type sites for work defined between humanly possible and the work of construction machinery.

Description

<Desc / Clms Page number 1>

The present invention relates to an all-terrain handling device with footed driver provided with a. uless two-wheel drive located at the ends of the branches-of the U-shaped chassis and equipped with a versatile tool-taking system allowing a great possibility of various and varied uses This device can be used for professional purposes or for private purposes by any individual without any special qualities or training.

The user accompanies the device, object of the invention, in its evolution by holding the steering handle and walking in. accom. movement of the device according to the movement controls which have been activated Handling operations are generally carried out by handling carts which lift the load cantilevered on the one hand require a driver's license for the driver and are expensive on the other hand.

Other devices exist which take charge of the frame but are motorized on the steering wheel on the one hand and are always of the driver-carried type. so j with a driving position and a duly trained operator.

Furthermore, the devices described above are used exclusively for handling and have no common use of tools or accessories.

 Large site works are mainly carried out with machines of size and cost unrelated to invention.

 However, there are vehicles of smaller size but for which the driver is on board and which are not at all suitable for handling.

In another register, handling and work operations are done by hand with essentially variable productivity.

 The device according to the invention avoids on the one hand the drawbacks of the solutions set out above and on the other hand combines work functions with handling functions in the context of construction sites or external works for applications in a range of works between the possible manually and the smallest machines existing on the market today. for a lower cost than the industrial trucks or the smallest site devices existing to date.

The tool interchangeability device with which the device, object of the invention is provided, makes it possible to multiply the possibilities of this device and therefore, overall, to lower the cost compared to the service rendered.

 The trolley according to diagram 1 is composed of a basic chassis (1) constructed in the shape of a D supported by two driving wheels (2) and (3) located at the end of the branches of the 0 and a steering wheel (4) articulated with respect to the chassis positioned halfway between the drive wheels. A steering drawbar (5) connected to the steering wheel allows the carriage to be steered

 This particular arrangement of the chassis allows on the one hand to take loads placed on the ground and on the other hand to transfer the weight of these loads most directly paçsihjesur the driving wheels.

A power assembly (6) supported by the main chassis and located above the steering wheel provides the power required to move the carriage by the wheels (2) and (3) and to the load lifting cylinder, located in the common attachment (10) and acting on the load taking tool (11).

All of the truck's power functions are controlled by appropriate controls located on the one hand above the steering wheel (4) and on the other hand controlled from the drawbar (5) by a cable device The truck is designed in such a way that the center of gravity G of the transported load is located near the axis of the drive wheels (2) and (3) and on the side of the steering wheel (4). This particular arrangement makes it possible to benefit as much as possible from the weight contribution on the drive wheels without having the risk of tilting the trolley The common attachment (10) allows with the same trolley to have multiple functions among which are the uses following: Lifting and moving of pallets on site or on flat ground.

Loading and unloading of bulk on site or on flat ground.

Lifting and moving of any pendulum loads or Big-Bags type for example; on site or on flat ground.

Lifting and moving of particular loads placed on the ground using a universal clamp, on site or on flat ground.

(12) serving as a bearing for the driving wheels, a hydraulic motor (13) and a 1-UP 1 1 transmission chain (14) connecting the hydraulic motor to the reducer of the driving wheel.

A third wheel (4) is mounted opposite the two wheels (2) and (3).

This wheel (4) is assembled by means of an axis (20) on the yoke (19) ~ and is attached to the vertical pivot bearing (18) of the chassis (1).

<Desc / Clms Page number 5>

A drawbar (5) linked to the yoke (19) by a hinge pin (30) and balanced by means of a spring (31) allows the carriage to be steered by orienting the steering wheel (4) The drawbar ( 5) is also equipped with movement controls and safety functions.

The set of driving functions essentially consisting of (7), (8) -and (9) is located substantially above the steering wheel (4), behind the common attachment device (10) and protected by a cover ( 16).

The heat engine (7) and the pump and tank assembly (8) are connected by a coupling (15) and are mounted on the support (17) secured to the chassis (1).

The distributor assembly (9) is also fixed on the (17) at the upper part thereof.

The command for raising and lowering the load is carried out from the drawbar (5) from the lever (27) and the cables (28) and (29).

The translation of the carriage is controlled from the distributor (9) by means of a base lever (42) directly mounted on the part driving the movable element of this distributor.

The control lever (21) of this distributor is assembled on the base lever (42) by means of a hinge pin (47) and a retaining ball (46) intended to limit the torque transmitted between these two pieces, for security reasons.

The travel control is produced from a rotating handle (26) associated with the cable reel (25) mounted on the drawbar (5) and connected to the control lever (21) by the cables (22) to control movement in one direction and (23) for controlling movement in the other direction.

An anti-collision safety device mainly composed of a safety bar (34) returned by a spring (35), sliding in the drawbar (5) on the one hand and attached to the lever (37) on the other hand is intended to stop the truck in the event of an accidental collision with the operator in accordance with the following operation: An operator contact on the safety bar (34) immediately pushes the latter into the drawbar and causes traction on the cable (40 ) This movement pivots the lever (41) around the axis (44) and consequently-drives the roller (45) towards the vee established in the base lever (42) with the effect of refocusing it by relative to its travel and therefore to stop any movement originating from the distributor (9).

In the event that this action is thwarted by a voluntary command of the movement, the safety device formed by the relative articulation of the levers (42) and (21) as well as by the locking ball (46) will come into action and allow the relative movement by means of the effort to be provided to overcome the recoil of the blocking ball of its housing The safety device as described therefore acts so as to give priority to the safety function over the voluntary movement command.

<Desc / Clms Page number 6>

An additional device actuates the anti-collision safety bar (34) during the angular movement of the steering drawbar (5) downwards or upwards just before being stopped by the mechanical limit stops.

This action is done in the same direction as in the case of contact with an operator.

A roller (38) mounted on the lever (37) itself articulated relative to the drawbar (5) by means of an axis (36) moves on a cam (39) integral with the yoke (19) and thus drives the anti-collision safety bar (34) in its movement causing a return effect to the neutral position of the dispenser drawer as described above.

A dead man's device constituted by a handle (49) mounted articulated by means of an axis (48) and returned by a spring (50) on the handle for controlling the translation (26) totally prohibits the operation of the engine by means of '' an electrical contact if it is not held in the tight position by the operator's hand.

On the other hand the drawbar (5) is equipped with a return spring (31) which systematically raises it in the event of abandonment by the operator and thus causes the translation to stop in accordance with the operation described above in the line 5.

The trolley according to the invention is equipped with a chassis (1) comprising a common attachment structure between the different tools (24) that it is required to support.

This structure consists essentially of U-shaped irons pierced with holes at the bottom of the profile and arranged opposite; the hollows of the profiles being positioned opposite so as to accept either the mounting of rolling rollers to obtain a guided rectilinear displacement or serve as a container for supporting adapted shapes such as for example a lifting mast.

The lateral holes (32) are used either to mount articulation axes according to the assemblies such as for example a pivoting arm or to mechanically fix the elements arranged in this device such as for example a lifting mast.

The invention is susceptible of multiple and varied industrial applications among which is the additional handling of pallets or various loads on small construction sites such as artisanal construction sites or the handling of various objects and small jobs. leveling in landscapers and municipalities.

On the other hand, many other handling tasks among those today carried out by hand are today possible with this device as soon as the frequency or the number of these handling operations is significant.
