Abstract

A plastic pallet provided with oblong channels in which reinforcing rods are locked. The locking is obtained by partially closing the end of a channel or by inwardly shrunk edge parts of openings in said channels.

Claims

1. A pallet of plastic material, comprising

an upper loading surface being defined about its periphery by side edges;

a plurality of blocks secured to the pallet and extending on the underside of and projecting down from the upper loading surface;

located underneath the upper loading surface and spaced inwardly from the side edges thereof, there is at least one oblong shaped reinforcing channel;

walls which are attached underneath the upper loading surface for defining the channel;

the channel having an upper side that is at least partly defined by the upper loading surface, the channel being shaped and adapted for removably receiving a reinforcing member;

a reinforcing member in said channel;

means for locking the reinforcing member in said channel in a removable way, the locking means comprising one of the walls that defines the channel being recessed, whereby the reinforcing channel for accommodating the reinforcing member takes an undulatory configuration in its longitudinal direction, so that the wall clampingly engages the reinforcing member.

2. The pallet of claim 1, wherein the wall that is recessed is recessed at spaced apart locations along the channel for defining the undulatory configuration.

6. The pallet of either of claims 1 or 3, wherein there are at least two intersecting ones of the channels which intersect in one of the blocks.

3. A pallet of plastic material, comprising

an upper loading surface being defined about its periphery by side edges;

a plurality of blocks secured to the pallet and extending on the underside of and projecting down from the upper loading surface;

located underneath the upper loading surface and spaced inwardly from the side edges thereof, there is at least one oblong shaped reinforcing channel;

walls which are attached underneath the upper loading surface for defining the channel;

the channel having an upper side that is at least partly defined by the upper loading surface, the channel being shaped and adapted for removably receiving a reinforcing member;

a reinforcing member in said channel;

means for locking the reinforcing member in said channel in a removable way, the locking means comprising one of the walls that defines the channel being recessed on the side facing the upper loading surface and another of the walls that defines the channel being recessed on the side thereof away from the upper loading surface, whereby the reinforcing channel for accommodating the reinforcing member takes an undulatory configuration in its longitudinal direction, so that the reinforcing member is removably clamped in said channel.

4. The pallet of claim 3, wherein the one wall is recessed at first spaced apart locations along the channel while the other wall is recessed at other spaced apart locations along the channel, thereby for defining the undulatory configuration.

5. The pallet of either of claims 5 or 3, wherein the channel has an entrance that is partially closed by an entrance closing wall.
