Description

Description.

  The invention relates to a transport trolley equipped

  of a conductor's platform connected solidly to an ex-

  end of the transport trolley opposite to the load receiving area Transport trolleys of this type are used

  especially as a shopping cart in warehouses.

  Drawbar forklifts or flatbed forklifts

  foldable shape for the driver are not affected by

this invention.

  In general, trolleys of this type are equipped with a rolling chassis, rigid, not suspended and

  solid plastic wheels. The platform of the con-

  conductor is integrally connected to the chassis of the carriage or is

  made in one piece with it. During operation-

  This rigid connection transmits vibrations from the drive unit and the chassis to the driver's platform without dampening them. Plus the shaking

  resulting from the coating of the taxiway or

  features thereof are transmitted directly to the platform

driver form.

  When a trolley of the type defined above

  above is used in storage roles, it comes in or

  be that the carriage collides with obstacles such as

  for example pallets or shelves. When passing over a slope, for example a ramp for loading a truck

  However, it may also happen that the driver's platform abuts against the surface of the taxiway. The platform of the driver of a transport trolley according to the invention can easily be damaged in this way. In addition, the shocks re-

  resulting from such a collision are induced directly in the driver's platform. During the operation of the carrier, the driver is thus exposed not only to

  vibrations and jolts, but also shock.

  The object of the present invention is to create a cha-

  riot transporter of the type defined above, whose ergonomics and comfort for the user are improved, which reduce the constraints mentioned above transmitted to the driver and which

  are as insensitive as possible to shocks.

  This problem is solved according to the invention in the

  case of a transport trolley of the type defined above, charac-

  terized in that the conductor platform is rotatably mounted about a transverse horizontal axis of rotation by

  relative to the longitudinal axis of the transport and

  bears at least one support horizontally distant from the axis of ro-

  tation, at least one elastic and / or damping component being

  o provided in the support area to limit the movement of ro-

  tation. The essential characteristic of the invention is, therefore, that the driver's platform is on the one hand rotatably mounted and on the other hand suspended and / or damped on the chassis of the transporting trolley. In the event of an impact with an obstacle, the joint with limited rotation of the platform

  of the driver allows the platform to escape, by the movement

  rotation about the axis of rotation, either up or down; the driver is thus protected against too violent shocks. The elastic and / or cushioned support of the

  platform provides significant comfort to the driver.

  According to an advantageous embodiment of the invention, the conductor's platform is fixed to rotation in at least two bearing points crossed by the axis of rotation on the

chassis of the transport trolley.

  Particularly advantageously, the points

  bearings have flexible elastic bearings. This

  requires an elastic and / or damped connection between the

  driver platform and chassis of the transported vehicle

tor.

  It is further advantageous that the elastic component

  that and / or shock absorber is provided on the upper side of

  support in an area far from the axis of rotation, the component

  Elastic health and / or shock absorber supports the conductor's platform on the chassis or a part of the transport trolley connected to the chassis. The driver's platform can thus be

  easy to fix in a basic, horizontal position.

  In addition, the mounting of the driver platform

  on the chassis of the transporting carriage is such that the conduct-

  protected against vibrations and jolts during

the movement of the carriage.

  Particularly advantageously, another

  elastic and / or damper component is provided on the underside

  of the support, in an area remote from the axis of rotation

  tion. If the platform collides with an obstacle during use of the transport carriage, these elastic components and / or shock absorbers serve as shock absorbers

  and absorb the kinetic energy of the transport cart.

  It is also advantageous for the support to be provided on the side of the axis of rotation opposite to the floor plate. The maximum travel of the driver's platform is defined because the elastic and / or damper component provided on the underside of the support comes into contact with the circulation surface. It is particularly advantageous if the area

  further away horizontally from the axis of rotation of the partition

  its substantially vertical from the conductor's platform, or spaced vertically from the transverse axis. It may

  to be obtained by means of a corresponding form of the front part

  conductor platform or inclined mounting

  of the driver's platform on the transport trolley.

  In the event of impact of the transporting trolley with an obs-

  tackle, this vertical distance combined with the force developed

  by the shock creates a torque around the axis of rotation. Of my-

  advantageously, the above-described area of the partition is vertically above the axis of rotation so that a shock causes the driver's platform to escape through

  upward rotation around the axis of rotation

  tion. This articulated and cushioned mounting of the driver's platform on the carrier vehicle improves ergonomics and

  driver comfort. At the same time, it reduces the con-

  tracks for the driver who keeps all his capacities during a whole working day and allows to obtain a

  high efficiency with the transport trolley.

  The articulated mounting of the conductor's platform on the chassis of the transport trolley facilitates the work of

  mounting and dismounting of the driver platform.

  In addition, thanks to the exhaust from the driver's platform in the event of an impact, it is prevented that the carrier or the driver's platform is too easily damaged. Another development of the invention provides for

  make the transport trolley as a commissioning trolley.

  The present invention will be described below, in more detail, with the aid of an exemplary embodiment.

  shown schematically in the accompanying drawings, in which: - Figure 1 shows a driver platform according to the invention, - Figure 2 shows a transport trolley equipped with a driver platform according to the invention, FIG. 1, the conductor platform 1 is fixed in rotation about an axis of rotation 2, horizontal,

  transverse to the longitudinal axis of the carrier, on the carrier itself not shown.

  Two bearing points 4 thus form the axis of rotation 2 and guide the platform of the conductor in an articulated manner to the chassis of the transporting carriage. To fix the conductive platform horizontally, at least one support 3 is provided, spaced from the axis of rotation 2; at the level of the support 3, there is at least one elastic and / or damping component to limit

the rotation stroke.

  The connection of the bearing points 4 and the chassis is

  made using flexible elastic bearings provided in bearing points 4.

  The elastic and / or damping component 5 is provided on the upper side of the support in an area remote from

  the axis of rotation and supports the conductor platform 35 on the chassis or on a component of the transport trolley

  linked to the chassis. The lower side of the support is also provided with another elastic and / or damping component 6, in the area remote from the axis of rotation. The support is on the side of the axis of rotation opposite to the floor plate 7. The zone of the partition 8 furthest from the axis of rotation 2 is spaced vertically from the axis of rotation. According to the figure

  1, this zone is chosen to be vertically above

above the axis of rotation.

  In the event of a collision with an obstacle, this

  vertical tance causes rotation of the platform of the con-

  conductor in the direction of arrow 9 around the axis of rotation. So the driver platform escapes upwards. The synthetic energy of the transporting trolley is then transformed on the one hand into potential energy induced in the

  conductor platform and on the other hand this energy is ab-

  absorbed by the elastic components and / or shock absorbers 5, 6.

  The maximum movement of the driver's platform is fixed by the elastic / shock-absorbing component 6 in that the latter

  abuts the traffic surface. In the event of a reverse

  port to the obstacle, the driver's platform tilts under the effect of its own weight and the driver to return in

  its rest position. Components 5 and 6 then provide each

  that both the role of a shock absorber and protect the con-

  conductor against the stresses linked to large shocks.

  The articulation of the conductor platform 1 on the chassis of the transporting trolley in flexible bearings and the elastic and / or damping component 5 also provide

  decoupling of the conductor from vibrations and shaking

  its and also generate significant comfort during

  the use of the transport trolley.

  FIG. 2 shows a transport trolley according to the invention equipped with a platform for the driver. According to a preferred embodiment, the carrier vehicle

  is in the form of a commission truck.
