Definitions

  • the present invention generally relates to a load protector for attachment to a fork back of a fork lift truck or for attachment to a wheel plate of a reach truck. Such fork lift truck or reach truck are used to replace loads.
  • the invention more particularly concerns a device protecting a load or the packaging of the load from being damaged by the fork back or by the reach truck.
  • Load protectors for a fork lift that attempt to mitigate damage to loads resulting from fork lifts are known.
  • UK patent application GB2478410A entitled “Load Protector for a Fork Lift Truck” for instance describes a load protector that consists of a resilient body with C-shaped cross section designed and dimensioned to encircle the vertical part of a fork arm. The load protector known from GB2478410A is held in position through straps that pass through apertures in the resilient body.
  • the load protector known from GB2478410A is made of a single body of hard rubber and therefore insufficiently protects a load from being damaged.
  • the single body of hard rubber typically does not protect the packaging of a load, e.g. made out of paper or cardboard, from being damaged.
  • GB2478410A suggests to provide some enhanced cushioning effect by relieving the surface of the load protector facing inward against the fork arm, e.g. through two or more grooves. The grooves improve the resiliency of the load protector slightly but still do not prevent the load protector from damaging sensitive loads or load packaging.
  • the load protector known from GB247841A is complex to attach to, to remove from or to replace along the fork arm because it requires opening and/or tensioning of straps.
  • the apertures required in the resilient body for the straps are vulnerable to cracks or rifts, particularly when the straps are opened or tensioned frequently, hence reducing the lifetime of the load protector.
  • anti-slip mats exist for forks. Such anti-slip mat is described for instance in United States patent application US 2013/0277151A1 entitled "Anti-Scratch and Anti-Slip Device for Lifting Loads, Preferably Through the Use of a Lift Fork".
  • the anti-slip mat is a rather thin device, typically designed to cover the horizontal part of a fork arm, and having a rubber top layer.
  • the rubber top layer has a high friction coefficient and therefore prevents a load that is picked-up by the fork lift from slipping off the fork. Since the top layer is made of rubber, the anti-slip mat also has anti-scratch properties, albeit limited.
  • US 2013/0277151A1 describes embodiments of such anti-slip mat with magnetic bottom layer that enables to removably attach the anti-slip mat to the horizontal part of the fork.
  • Japanese patent application JP10-291793 describes embodiments of such anti-slip mat that are pressed onto the fork arm and consequently are not intended to be removed from the fork arm.
  • Both, US 2013/0277151A1 ( Fig. 9 ) and JP10-291793 ( Fig. 3 ) show embodiments where the anti-slip mat is extended to also cover the lower vertical part of the fork arm.
  • JP10-291793 ( Fig. 5 and Fig. 6 ) also suggest to provide grooves or short protrusions, i.e. knobs, in the upper surface of the anti-slip mat to further improve the friction and consequently the anti-slip behaviour between fork arm and load.
  • anti-scratch properties are associated with the anti-slip mats known from US 2013/0277151A1 and JP10-291793 , these devices are disadvantageous as load protectors in many aspects. Firstly, these anti-slip mats remain thin devices with an even thinner rubber top layer that remains hard, even if grooves or knobs are foreseen. The hardness of these anti-slip mats makes them unsuitable to prevent damage to load packaging. Secondly, anti-slip mats are designed to cover the horizontal part of the fork arm (where the load can slip off) and at best the lower vertical part of the fork arm. A load that extends beyond the pallet however typically is damaged by the higher part of the fork arm.
  • a straightforward solution to prevent a load or load packaging from being damaged by fork arms resides in putting the load into a metal container and replacing the metal container with a fork lift.
  • the fork arms may damage the metal container but will not touch or damage the load. This however requires metal containers and additional handling of the load to put it in the container and take it out of the container afterwards.
  • an improved load protector i.e. a device that enables to protect a load or its packaging from being damaged by the upright parts, e.g. the vertical or nearly vertical parts of a fork or reach truck, and that overcomes one or several of the above described shortcomings of existing devices. More particularly, it is an objective of the present invention to describe a load protector that also protects fragile loads and/or the packaging of loads in paper or cardboard from being damaged, and/or that protects loads that exceed the pallet size from being damaged by the higher vertical parts of the fork arm or reach truck, and/or that is more durable, and/or that is easily removable or displaceable, and/or that does not affect the load diagram of the fork.
  • the load protector adapted for attachment to a fork back of a fork used for replacing a load or to a wheel plate of a reach truck, defined by claim 1, the load protector comprising:
  • the load protector according to the present invention has a fibre structure extending from the top surface of the solid base, i.e. a resilient body made of natural or synthetic rubber.
  • the fibre structure consists of (natural or synthetic) rubber fibres with a length of at least 1 centimetre.
  • the fibre structure will not damage an approaching load or the packaging thereof while the driver of the fork lift truck or reach truck will experience increased resistance while the fibres are pressed and/or bended by the approaching load.
  • the rubber fibres provide sufficient flexibility to slow down the approaching load without damaging it, while the driver gets sufficient time to notice the increasing resistance and anticipate thereon.
  • the fibres have a length of at least 15 millimetres. The longer the fibres are, the more flexible they are as a consequence the risk they damage fragile loads or packaging of loads is further reduced. Longer fibres however provide less resistance as a result of which their signalling function to the driver of the fork lift truck or reach truck decreases.
  • Embodiments of the load protector according to the present invention, defined by claim 2, further comprise:
  • One or more magnets incorporated in the bottom surface of the resilient rubber body i.e. the surface opposite of the fibre structure, enable to take benefit of the magnetic properties of the fork back. Thanks to such magnets, the load protector can be attached to and detached from the fork back manually by the driver of the fork lift truck. The driver hence can remove the load protector, for instance if additional fork space is required to lift a certain load, and keep the load protector in or near the fork lift truck without having to store the load protector centrally. As soon as the driver desires to use the load protector again to avoid damage to new loads to be lifted, he can manually attach the load protector to the fork back without any tools.
  • a bottom surface of the solid base has an amount of openings provided with screw thread, each opening of which is dimensioned to hold one of the magnets.
  • the bottom surface of the rubber body preferably is provided with openings foreseen with screw thread at their inner surface. Powerful magnets can then be screwed into the rubber body, enabling to attach the load protector to the fork back without risk for being displaced while driving or while picking up a load.
  • Embodiments of the load protector according to the present invention, defined by claim 4, further comprise:
  • embodiments of the load protector according to the present invention that are destined to be attached to the wheel plate of a reach truck preferably rely on mechanical attachment rather than on magnetism because the wheel plate is too small to rigidly attach a load protector thereon via magnets.
  • a U-profile, turned upside down and mounted onto the bottom surface of the rubber body may enable to attach the load protector to the wheel plate, provided the width of the U-profile is sized to correspond with the thickness of the wheel plate.
  • a first plate may be mounted on the bottom surface of the rubber body.
  • a second plate for instance identical to the first plate, and held substantially parallel to the first plate, may be connected to the first plate through screws and bolts such that the wheel plate of the reach truck becomes clamped in between the first plate and second plate.
  • Such embodiment of the load protector according to the present invention has the advantage that it can be used on any reach truck, independent of the thickness or height of the wheel plate, whereas the above described embodiment with U-profile can be used only on reach trucks with certain thickness of the wheel plate.
  • the lower ends of the first plate and second plate are provided with grooves such that one of the screws and bolts can be height adjusted to fit the height of the wheel plate whereon the load protector is mounted.
  • the plural fibres each have a diameter in the range from 1 millimetre to 7 millimetres.
  • the preferred diameter for the fibres extending from the top surface of the rubber body preferably lies in the range from 3 to 7 millimetres, and is chosen as a trade-off between flexibility, i.e. reduced risk for damaging the load, and resistance, i.e. feedback to the driver that the load is approaching the fork back.
  • load protectors whose fibres have even smaller diameters, in the range between 1 millimetre and 3 millimetres.
  • the plural fibres are arranged in a pattern such that neighbouring fibres have an inter distance in the range from 3 millimetres to 10 millimetres.
  • the number of fibres and their inter distance is chosen as a trade-off between flexibility and resistance.
  • a regular diamond pattern is preferred wherein fibres of a row are equidistantly spaced in between fibres of the previous row.
  • the inter distance between two neighbouring fibres in a single row preferably is selected in the range from 3 millimetres to 10 millimetres, giving fibres sufficient space to bend when pressed by a load without damaging the load, while providing sufficient resistance to the load to signal the driver that the load is approaching the fork back or reach truck.
  • the said solid base has a height of at most 30 millimetres.
  • the load diagram of fork lifts does not change when the load is positioned at 30 millimetres distance from the fork back.
  • the solid base of the load protector has a height of at most 30 millimetres, the driver can be instructed to drive against any load up to the point where the fibres are pressed completely and the load reaches the solid base.
  • the load diagram of the fork lift will not change since the load will be at a distance of at most 30 millimetres of the fork back in such circumstances, and the driver can thus safely tilt any load up to the maximum load of the fork lift truck.
  • the solid base of the load protector according to the present invention may be higher than 30 millimetres when used on fork lifts that are over-dimensioned, i.e. fork lifts whose maximum capacity exceeds the loads that will be tilted.
  • a bottom surface of the solid base is provided with a pair of side rims adapted to hold the load protector in position in case a force is applied with a horizontal component.
  • the bottom surface of the rubber body i.e. the surface that is in touch with the fork back of the fork or that is in touch with the wheel plate, has side rims that avoid a horizontal displacement of the load protector when a horizontal force is applied to the fork, to the reach truck or to the load protector, or avoid a horizontal displacement of the load protector while the lift truck or reach truck moves.
  • the side rims have a height in the range from 3 millimetres to 10 millimetres, preferably 5 millimetres.
  • the height of the side rims must be sufficient to keep the load protector in position when a horizontal force is applied.
  • a height of 3 millimetres may be sufficient.
  • bigger and heavier load protectors like for instance the ones used on the fork back of fork lifts, a rim height of 5 millimetres up to 10 millimetres is preferred.
  • the solid base has a width in the range from 50 millimetres to 145 millimetres.
  • the rubber body with fibre structure has a width that slightly exceeds the width of the fork back or the width of the wheel plate whereon it will be used.
  • the width of the load protector preferably corresponds to the width of the fork back (or wheel plate) plus twice the width of the side rim if side rims are foreseen at the bottom surface. For typical forks, this means that widths in the range from 50 millimetres to 145 millimetres are preferred. However, load protectors having a smaller width may also be manufactured. On wheel plates of reach trucks, it may for instance be desirable to have two smaller load protectors side by side.
  • the solid base has a length in the range from 150 millimetres to 700 millimetres, preferably in the range of 400 millimetres to 600 millimetres.
  • load protectors having a length in the range from 400 millimetres to 600 millimetres to cover the entire part of the fork back that may possibly damage the load.
  • Embodiments of the load protector that are used on wheel plates of reach trucks however must be smaller and shall have typical lengths of 150 millimetres to 300 millimetres, required to cover the wheel plate over its entire height.
  • the solid base and the fibre structure are integrally formed through injection moulding.
  • an advantageous way to produce the rubber body with top fibre structure relies on injection moulding.
  • Elements positioned in the mould will enable to create the fibre structure such that the fibre structure integrally forms part of a single rubber piece integrating the solid body and the fibres.
  • the openings with screw thread are formed in the solid base through vulcanisation.
  • a vulcanisation technique may be applied. Since screw thread cannot be realized through injection moulding, an additional vulcanisation step may be required to create the openings for the magnets and form the screw thread therein.
  • the polymer or rubber in the load protector according to the present invention is reinforced through fiberglass.
  • the present invention also concerns a related manufacturing method for a load protector adapted for attachment to a fork back of a fork used for replacing a load or to a wheel plate of a reach truck, the manufacturing method being defined by claim 16, comprising:
  • Embodiments of the manufacturing method according to the present invention, defined by claim 17, further comprise:
  • Embodiments of the manufacturing method according to the present invention, defined by claim 18, further comprise:
  • Embodiments of the manufacturing method according to the present invention, defined by claim 19, further comprise:
  • Fig. 1 shows a fork lift truck 100 that is used to tilt and replace loads, for instance from a storage space towards the trailer of a truck.
  • the fork lift truck 100 has a fork with two fork arms 101 and 102.
  • the fork arms 101 and 102 have horizontal parts that are dimensioned to fit into openings of a standard pallet whereon the load is placed, and vertical parts, also called fork backs.
  • a load protector 200 is attached to each of the fork backs.
  • Fig. 2 shows in more detail the load protector 200 that is attached to the fork backs of the fork lift truck 100 of Fig. 1 .
  • the load protector 200 has a rubber cuboid base 201 with length of 600 millimetres, width of 120 millimetres and height of 30 millimetres.
  • the load protector 200 further has a top fibre structure 202 that consists of rubber fibres, extending from the top surface of the rubber base 201.
  • Each of the rubber fibres has a length (or height) of 20 millimetres and a diameter of 5 millimetres.
  • the rubber fibres are positioned in a pattern of rows. The fibres on each row are positioned in the middle between the fibres of the previous row and consequently also in the middle between the fibres of the next row.
  • the distance between neighbouring fibres in a row is 10 millimetres.
  • the base 201 and fibre structure 202 are integrally formed via a single injection moulding step. Thereto a hole-pierced block is positioned in the mould during the polymer or natural rubber injection, to shape the fibres.
  • Fig. 3 shows the bottom surface of the rubber base 201 of load protector 200.
  • Two side rims 204 are provided along the edges of the base 201. These side rims 204 have a height of 5 millimetres.
  • the side rims 204 constitute a border that keeps the load protector 200 in horizontal position when attached to the fork back.
  • the side rims 204 in other words avoid that the load protector 200 slides horizontally when forces are applied with a horizontal component, for instance as a result of movements made by the fork lift truck.
  • the bottom surface of the base 201 further has five openings 203 for magnets. These openings have a diameter of 33 millimetres and are made in the solid rubber base 201 through a vulcanisation technique.
  • Fig. 4 shows in more detail a part of the bottom surface of the rubber base 201 of load protector 200.
  • This drawing again shows the side rims 204 and one of the openings 203 sized to fit a magnet 400 with diameter of 32 millimetres.
  • the depth of the opening 203 coincides with the thickness of the magnet 400.
  • the magnet 400 further has a pin 401 with screw thread and the bottom surface of the magnet opening 203 further has a hole 205 the inner surface of which is provided with M6 screw thread enabling to fix the magnet 400 therein.
  • the magnets 400 hence are tightened into the bottom surface of the rubber base 201 such that the top surface of the magnets 400 and the bottom surface of the base 201 form an integral fat surface that will be in touch with the surface of the fork back.
  • the magnets 400 are preferably screwed into the base 201 because temperatures in the range of 300°C would damage the magnetic properties of the magnets 400 should one integrate the magnets in the base through a baking process.
  • the magnets 400 are selected and dimensioned to enable attachment of the load protector 200 to the fork back and prevent vertical sliding thereof along the fork back when certain forces with vertical component are applied. Five magnets, each having a force of 40 kg, may for instance be adequate.
  • Fig. 5 shows a reach truck 500.
  • Such reach truck 500 is used in shops to fill racks with pallets that carry a load.
  • the reach truck has a fork to lift the pallets and has horizontal beams running parallel with the horizontal parts of the fork arms.

  • Each of these load protectors comprises a solid, cuboid rubber base 601 with length of 50 millimetres, width of 25 millimetres and height of 20 millimetres.
  • the load protector further comprises a rubber fibre structure 602 of fibres that each have a diameter of 1 millimetre and a length of 15 millimetres, extending from the top surface of the solid base 601. The distance between neighbouring fibres in a row is 3 millimetres.
  • the load protector further comprises a metal U-profile 603, one leg of which is fixedly mounted onto the bottom surface of the rubber base 601 such that the U-profile 603 enables to attach the load protector to the wheel plate 501 by sliding the U-profile downward over the top edge of the wheel plate 501.
