Definitions

  • the invention relates to a plastic pallet with an upper part and three or more runners.
  • Pallets are used to store and transport goods.
  • the pallets keep the goods off the floor so that they can be lifted and transported by a forklift. They usually consist of a flat upper part and, in the case of pallets in the size of 1200x800mm, of three runners, which can be manufactured in one piece via injection molding or in several parts. Multi-part plastic pallets are easier and cheaper to manufacture and consist, for example, of an upper part and a lower part, which are joined together and connected in an interlocking manner.
  • the lower part usually has three runners and nine feet.
  • the upper part and the lower part, or the runners, can be connected to one another by welding, as described in CH702628 or CH685549.
  • a bead is formed which has to be removed with a milling process so that the pallet has a smooth surface. This is time consuming and expensive.
  • a plastic pallet is disclosed with a flat upper part and a flat lower part as well as nine separate feet via which the upper and lower part are connected to one another, with both ends of the feet being fastened to the upper part and lower part of the pallet by means of snap locks.
  • US Pat. No. 5,483,899 discloses a pallet with a lower part and an upper part which can be pushed into one another, the lower part of the pallet having ribs with a snap element which is arranged at the upper end of a rib in each case. This snap element at the upper end of the ribs of the lower part of the pallet creates the snap connection with the upper part.
  • No. 5,794,543 A describes a modular pallet system with individual lower floor elements and an upper element with a primary surface.
  • the system comprises complementary engagement elements of the upper and lower elements which interlock and connect the upper and lower elements to one another.
  • the known multi-part plastic pallets have the disadvantage that the connection between the different parts can loosen under constant load and the upper part separates from the feet or the runners.
  • the present invention is based on the object of specifying a multi-part plastic pallet which allows a connection between the upper part and the runners, this connection being better able to withstand the load caused by an impact of the pallets during transport and, if possible, not even under high stress opens.
  • a plastic pallet with an upper part and runners, the upper part being provided with outer and central female foot parts and the runners with outer and central male foot parts, the male foot parts of the runners being slidable into the female foot parts of the upper part, and wherein in the assembled state of the plastic pallet, the male foot parts form feet with the female foot parts.
  • the foot parts of the upper part and the foot parts of the runners can be fastened to one another by means of snap connections.
  • Each male foot part comprises at least two snap hooks, which are arranged in pairs with mirror symmetry and which each have a flake head with flint cut, a snap arm and a back, the flint cuts of the flake heads facing away from each other and the backs of the snap hooks facing each other.
  • Each female foot part comprises at least one latching element into which the flake heads are latched in the assembled state and each form a snap connection.
  • the female foot parts are integrally connected to the upper part.
  • a gap is arranged between the rear sides of the snap hooks.
  • Each female foot part comprises at least one securing element, each with a free end, the securing element being integrally connected to the female foot part, and the securing element protruding into the space between the rear sides of the snap hooks so that the snap hooks remain in the locked position.
  • the arrangement of the at least one securing element between the snap hooks arranged in pairs enables the snap hooks to be retained in the locked position when the plastic pallet is plugged together and cannot be released from the locked position without an additional tool.
  • the securing element leads to a secure connection between the upper part and the foot parts of the runners and thus secures the attachment of the runners to the upper part.
  • the respective free end of the at least one securing element is preferably tapered towards its center. The free end can be rounded or pointed towards the middle.
  • the shape of the free end of the securing element, which tapers towards the center, is particularly suitable so that the snap hooks can more easily slide into the desired locked position when the runners are plugged together along the securing element.
  • the free end of the at least one securing element is preferably symmetrically pointed.
  • the free end of the at least one securing element preferably has an arrow-shaped cross section.
  • the symmetrically pointed end is advantageous so that each snap hook is guided along a beveled surface of the free end of the securing element when the pallet is put together.
  • a securing element can also have a plurality of free ends, preferably arranged next to one another, which preferably tapers towards the center, even more preferably are symmetrically pointed.
  • the snap hook with flak head and flint cut is made wide in order to enlarge the snap connection area between flak head and snap-in element and to reinforce the snap connection.
  • the at least one securing element preferably has two free ends between a pair of snap hooks which tapers towards the center, preferably are symmetrically pointed.
  • Each snap hook includes a snap arm, a back and a flake head with flint cut.
  • the flak head has an essentially straight rear side and a front side with a flint cut.
  • the last part of the back of the snap hook in the area of the flak head that leads to the tip is beveled or rounded, preferably beveled. This means that the tip of the flak head is weakened at the end of the snap hook and at Plugging the runners together in the upper part does not interfere with the free end of the securing element.
  • the snap hook has resilient properties.
  • the latching element has at least one recess into which the hook head of the snap hook can engage.
  • the latching element can also have two recesses, in each of which a hook head of a pair of snap hooks engages.
  • the latching element has an elongated shape in cross section, the recesses being arranged in each case on the longitudinal sides of the latching element parallel to the width of the hook head.
  • Each hook head of the snap hook engages in a recess of the latching element and the undercut of the hook head forms a snap connection together with the latching element.
  • a snap connection is a form-fitting connection and is formed by a hook head with an undercut and a snap-in element with a recess, which are designed as counterparts.
  • the hook head engages in the recess of the latching element and the area of the undercut of the hook head latches into the latching element.
  • Such a snap connection has the advantage that the connection is pressed into one another when loaded, which additionally strengthens the connection.
  • this snap connection has a resilient property when loaded.
  • each foot has one or more snap connection pairs, preferably one or two pairs.
  • the feet can also have four snap connection pairs and thus eight snap connections, preferably on the outer feet of the middle runner. Due to the multiple snap connections, the strength of the feet is further increased and secured.
  • the female foot parts of the upper part have an outer wall with ribs and the male foot parts of the runners have an inner wall with ribs.
  • the outer wall of the female foot parts preferably encloses the male foot parts.
  • the outer wall of the outer female foot part extends essentially over the entire length of the outer male foot part, so that the outer male foot parts of the runners can be pushed completely into the outer female foot parts of the upper part.
  • the outer wall of the female foot parts surrounds the male foot parts in such a way that the male outer foot parts are completely protected in the event of an impact.
  • the outer wall extends over the entire fleas of the outer female foot part, preferably essentially around the entire foot. Total fleas is understood to mean that the outer wall of the outer female foot parts extends from the top of the pallet to the bottom of the runner, which can be placed on a support surface.
  • the outer wall preferably extends around the entire foot, with the exception of a recess for a connecting piece of the runners, which connects the outer male foot parts with the central male foot part.
  • the outer wall extends on at least three sides of the outer female foot parts from the top of the pallet to the bottom of the runner.
  • the ribs of the female foot parts and the ribs of the male foot parts preferably extend over substantially the entire length of each foot part.
  • the ribs can have different cross-sections and, for example, have a T-shaped, angled or rectangular cross-section.
  • the ribs of the female foot parts and the ribs of the male foot parts can be pushed into one another completely.
  • the male foot parts of the runners preferably have an inner wall with ribs, which act as spacers between the inner wall and the serve the outer wall. These ribs also serve on the one hand as a guide when the runners are plugged together with the upper part of the pallet, and on the other hand they form a distance between the inner wall and the outer wall, which serves as additional impact protection. When the plastic pallet hits an object, the ribs can bend slightly and briefly reduce the distance between the inner and outer walls, which dampens the impact.
  • the plastic pallet preferably has three runners, each with two outer male foot parts and a central male foot part.
  • the plastic pallet according to the invention preferably has three longitudinal runners. This is the case, for example, with plastic pallets of the standard size of 1200x800mm.
  • the outer male foot parts are inserted into the outer female foot parts and form outer feet, which are provided on the short transverse side of the plastic pallet.
  • the middle female and male foot parts, which form the middle feet, are preferably provided in the middle of the pallet across the long side.
  • the plastic pallet has more than three runners, for example five or six runners.
  • five or six runners are preferred for pallets of size 1200x1000mm.
  • a pallet of this type is possible with five runners, of which three runners run in one direction and two runners in the transverse direction along the sides of the pallet.
  • the pallet comprises six runners, three longitudinal runners and three transverse runners.
  • all of the outer eight feet preferably have outer walls that extend at least on the outside of the feet, i.e. on the side that is arranged on the edge of the plastic pallet, over the entire height of the outer female foot parts.
  • the upper part of the plastic pallet preferably has a flat top.
  • the top has a continuous closed surface.
  • the underside of the upper part preferably has Cross bracing to reinforce the upper part.
  • the upper part comprises reinforcement tubes which additionally reinforce the upper part of the plastic pallet.
  • the male foot parts of an individual runner can be pushed into the foot parts of the upper part separately from the male foot parts of the other runners.
  • the three runners can thus be individually inserted into the upper part and the plastic pallet can be made from four pieces.
  • the three runners are connected to one another and consist of one piece, so that the plastic pallets can be plugged together from two pieces, the upper part and a lower part provided with runners.
  • the foot parts of the upper part and the foot parts of the runners are preferably integrally connected to the upper part or to the runner. This design, together with the snap connection, enables a pallet to be assembled from just two or four parts and without the aid of tools.
  • the male foot parts with the inner wall and the ribs are preferably pushed completely into the female foot parts with the outer wall and the ribs, so that their ribs are completely pushed into one another and are arranged parallel to one another over their entire length , whereby the feet of the pallet are formed and the inner walls of the male foot part and the outer walls of the female foot part form double walls of the feet.
  • the double walls increase the strength of the feet so that they are more robust, withstand impacts from a heavy lift truck or other objects and can therefore be used over a longer period of time.
  • the construction of the feet allows the two parts of the pallet to be assembled quickly and easily, and the snap connection enables efficient locking without the need for tools. If desired, the Snap connection can still be opened again by grasping with a screwdriver per snap hook from the underside of the runner between snap hook and snap-in element and pushes the snap hook out of the snap-in element. However, this is not possible without an additional tool.
  • the arrangement of the pallet according to the invention means that the male foot parts of the runners are protected by the female foot parts of the upper part.
  • the outer feet in particular are exposed to strong forces.
  • the male foot parts of the runners are protected by the outer wall of the outer female foot parts, which extends over the entire fleas of the outer male foot parts.
  • shear forces arise, which are intensified by the weight of the goods being transported on the upper side of the pallet.
  • these forces are directed into the floor via the upper side of the pallet and the female foot parts.
  • the feet of the upper part and not the feet of the runners are loaded. As a result, the snap connection can withstand strong impacts and does not come loose even under constant load.
