FR2777524A1 - Accessory holder for industrial truck - Google Patents

Abstract

The accessory holder has a clamping device by which it is fastened on a vertically disposed rod-form component(10) of the truck. The holder is fixed to any desired point on the rod and at any angle. The rod-form component is cylindrical in the main and also acts as an aid for climbing up onto the vehicle. The holder has a rotatable lever(21) and the position of its first axis in relation to the rod does not change as a result of the lever's rotation

Description

I The present invention relates to an accessory support intended to be

  fixed to a transport trolley comprising at least one accessory which is fixed to the trolley

  carrier in the driver's location area.

  Accessory supports are used on

  transport trolleys for fixing different acces

  evenings. Possible accessories are, for example, a document holder, a writing tablet or a drink holder, a computer terminal, a radio or

  data transmission or a hand-held detector.

  It is preferable to mount such accessories for

  that they are easily accessible from the location of the

  conveyor carriage driver without disturbing the driver for

  maneuver the trolley and to carry out the usual operations-

  the. These include order pickers

  for whom during the work of

  the driver has a particularly wide radius of movement

  important, so it is difficult to find a provision

  advantageous sition for the accessory suitable for all

operating situations.

  The present invention aims to develop a

  accessory support intended to be fixed to a trolley

  carrier which can be easily mounted on the trolley and can be removed under the same conditions, which can

  to adapt in different positions on the trolley.

  The invention also aims to develop a transport carriage equipped with an accessory support according to the invention. To this end, the invention relates to an accessory support of the type defined above, characterized in that the accessory support comprises a clamping device for fixing the accessory support to a workpiece in the form of

trolley bar.

  The accessory holder can be pinched anywhere in a bar-shaped part. If the transport trolley has several pieces in the form of bars, the accessory support can be fixed on any of these pieces. The bar-shaped parts are

  for example structures in the form of columns but also

  bar segments of a tube grid or

a tubular arch.

  If the bar-shaped part is practically vertical, there is the advantage of being able to pinch the support to a

  any part of the bar-shaped part.

  The bar-shaped part of the forklift can have an essentially cylindrical shape. The accessory support can then be pinched at any angle on the bar-shaped part. It is particularly advantageous for the carriage

  carrier or an order picker, pre-

  a low-level order picking trolley

  lifting. It is particularly important for each

  riots order preparers to be able to adapt the position of an accessory to individual requirements, because on such a cart, the driver moves very intensely. In the case of order picking trolleys with a low height

  lifting, the driver generally has frequent access to the

  trolley to be in a standing position,

  raised. For this, he should not be hindered by any access

  evening. It is thus possible that the bar-shaped part of the transport carriage constitutes a means facilitating

  access to the trolley. A low-order order picking truck

  ble lifting height equipped with such a means is described in

document DE-196 18 906-A1.

  According to an advantageous constructive embodiment, the accessory support comprises a lever rotating around a first axis and the position of the first axis relative to the bar-shaped part must not change if the lever is rotated. The position of the axis of rotation of the lever thus remains unchanged during the tightening of the clamping device independently of any elastic deformations, for

  compared to the bar-shaped part.

  The position of the first axis is defined by a

  bracket which surrounds the bar-shaped part. The stirrup pre-

  essentially feels U-shaped and fits around the bar-shaped part. The lever can then be hung

  on the caliper so as to turn around the first axis.

  A clamping member is provided on the lever, the distance from which in relation to the bar-shaped part can be modified by rotation of the lever. The bar-shaped part can thus be pinched between the clamping part and the stirrup. The clamping piece capable of turning can be fixed on the lever around a second remote axis and parallel to the first axis. It is also possible to rigidly fix the clamping piece on the lever and give it

  an asymmetrical shape with respect to the first axis.

  The present invention will be described below from

  in more detail using exemplary embodiments

  shown schematically in the accompanying drawings in the-

which:

  - Figure 1 is a perspective view of a cart prepared

  rator of control at low lifting height, - Figure 2 shows an accessory support according to the invention, - Figure 3 is a side view of the accessory support in the released position,

  - Figure 4 shows the accessory support in the service position

rée,

  - Figure 5 shows a clamping part.

  Figure 1 shows a fuel cart

  at low lifting height. The driving part 1 of the cha-

  riot order picker includes a driver station 2 with a guardrail 3 and control elements 4. On the other side of the driver station 2 is a box 5 which can be mounted and which accommodates for example the group carriage drive. The housing 5 according to this example of

  realization includes for example a padded backrest 6 for-

  mant a harness for standing driver.

  The load part 7 of the food preparation trolley

  control includes a battery compartment 8 as well as a

  che 9 to receive the load; this fork can for example

  take pallets, lift and transport them.

  To also reach the products which are in a second shelving plane, the conductor can mount on the accessible housing part 5. To facilitate the climb to the housing part 5 and then allow the driver to stand, the housing part 5 includes

  side of the load, behind the backrest 6, an aid to the

  tee formed by a piece 10 in the form of a bar.

  Figure 2 shows an accessory holder on the

  bar-shaped part 10. The accessory holder consists of

  fitting of a stirrup 20 which surrounds the part 10. The stirrup 20 carries in rotation a lever 21. The lever 21 is moved

  nor of a clamping piece 22 movable in rotation. When the lever 21 occupies the position shown, the bar-shaped piece 10 is pinched between the stirrup 20 and the clamping piece 22. If the lever 21 is turned upwards, the clamping piece 22 deviates from the bar-shaped part 10, this

  which allows you to slide or remove the accessory support.

  The not shown part of the accessory which is for example a document holder or a radio data transmission device is preferably effectively connected with the bracket 20. FIG. 3 shows the accessory support in the loose state. The reference A designates the axis of rotation of the lever 21 relative to the caliper 20. This axis of rotation A does not change position relative to the caliper 20. The axis of rotation B is offset relative to the 'axis of rotation A; this axis B is the axis of rotation of the clamping piece 22 on the

lever 21.

  By turning the lever 21 downwards, the axis of rotation B performs a circular movement around the axis of rotation A. The distance from the axis of rotation B and thus of the clamping piece 22 relative to the piece 10 decreases, which ultimately leads to the tightening of the locking device

  on Exhibit 10. This situation is represented by the dis-

positive of figure 4.

  FIG. 5 shows another preferred embodiment of the clamping piece 22a. This piece of ser-

  rage 22a is fixed here in rotation with the lever

  21. Two pins 30 are provided, with a central axis 31 for locating

  ger in the corresponding openings of the lever 21. With respect to the lever 21, the clamping piece 22a is locked in

  rotation by pins not shown.

  Relative to the bracket 20, the clamping piece 22a can rotate around the axis A. The position of this axis A

  is predetermined by the envelope line of the cylin-

  drique 32. The clamping piece 22a has a surface

  33 peripheral attack, curve which is mainly sy-

  metric with respect to the B axis. The B axis is offset from the A axis but parallel to it. By turning the clamping piece 22a around the fixed axis A, the bearing surface moves to approach or move away from the bar-shaped piece 10.15
