Pallet intended for transport of long elements, especially plastic sections

Abstract

 A pallet consists of a fixed base (1) and posts (2) perpendicular to the base, between which two symmetrical rotary frames (4) are hung with two rows of spring clamps (5,6). Within the area of the base two rotary beams (15) are installed, equipped with two rows of parallel stabilising components (21,22) on the opposite surfaces of the beams (15). The movable frames (4) can be locked in at least two stable positions by means of mandrels (8). The transported elements are placed between the stabilised frames (4) and are hold by the spring clamps (5,6) and the stabilising components (21,22), so that they do not contact each other.

Description

[0001] Subject of the invention is a pallet intended for transport of long elements, especially plastic sections, as i.e. vehicle bumpers.

[0002] There is a known invention registered in Poland under no. 353901 "Paleta ladunkowa do dlugich towarów" [The freight handling pallet intended for transport of long products".] The device consists of two parallel longitudinal members of a frame, connected by several cross-bars and a posts perpendicular to them installed in certain distances from each other. Particular pallets can be stacked one on the other with shift by the post width as well as one on the other the way that the loading space required by the pallets is small.
Other known solution according to the patent application PCT/SE00/01660, Polish application no. 356818 named "Paleta ladunkowa przestrzenna" [Spatial freight handling pallet] consists of two sidewalls that connected with the pallet form a box opened at the top side. The pallet is equipped with a middle wall, dividing the loading space to the parts and is equipped with at least one holder supporting back side of the opposite side wall. The device is also equipped with expanding device, which changes the mutual position of the holder and the middle wall.

[0003] The pallet intended for transport of long elements according to the invention consists of the frame base structure with rectangular outline. In the rectangle corners the perpendicular posts are installed, between which, along the longer rectangle sides, the rectangular rotary frames are installed symmetrically. On the external surfaces of the longer sides of each frame the hook shape spring clamps are installed at a uniform distance, with a holder which longer arm passes through opening in the frame and which is equipped with spring wound on it, limited by a nut at the bottom and by the bottom part of the frame side from the top. The distances between spring clamps are different at each side of the frame. The frame is equipped with lock, which enable blocking it stable in reference to the base in at least two positions. The lock consists of a movable mandrel installed at one end of the frame, at its shorter side in some distance from the rotation axis and of at least two openings made in the post or other fixed component of the pallet, symmetrically in reference to the frame rotation axis. Between internal surfaces of the pallet base shorter sides, the two beams of rectangular cross-section are hung symmetrically. Perpendicular to the opposite beams surfaces the fixed stabilisation elements are installed, which consist of hooks at one side and the pins at the other side. The distances between those components are corresponding to the distances between spring clamps of the side frames. At one end of each beam there is a flat, perpendicular arm with movable mandrel at the end and in the opposite pallet side there are two openings symmetrically located in reference to the beam rotation axis. Placing the mandrel in one of the openings stabilises the beam in one of two working positions shifted by 180°. In front surface of the shorter base side there are two passable recesses with spacing between them corresponding to the distance between a fork lift truck forks.

[0004] The main advantage of the pallet according to the invention is the possibility of the transported elements stabilisation the way that the elements do not contact each other and the same are not subject of paint damages or breaking of details with simultaneous maximum use of the loading space. The rotary frames and beams of the pallet provide quick preparation of the pallet for transport of at least two types of elements with different depth and after stabilisation of the frame at various angles in reference to the base, also preparation of the pallet for transport of elements with different length is provided.

[0005] The invention is explained in details on the figures presenting example of the pallet made for transport of two vehicle bumpers types with different depth. Fig. 1. presents perspective view of the device, fig. 2 the side view, fig. 3 view of the pallet side part with enlarged frame lock components and the spring clamps in perspective, fig. 4. view of the corner with frame lock seen from the pallet inside in perspective, 5. view of the pallet corner with beam lock seen from the pallet inside in perspective.

[0006] In the base 1 corners of the pallet the perpendicular posts 2 are installed. Between the posts, the rectangular rotary frames 4 are hung on axes 3 equipped with rows of spring clamps 5 and 6. On the side 7 of the frame there is a movable mandrel 8 and in the post there are two openings 9 and 10 located opposite to the mandrel in two positions of the frame when it is perpendicular to the base 1. The mandrel 8 inserted to the opening 9 or 10 stabilises the frame in this position. The spring clamp 5, 6 is in the shape of hook, which arm 11 passes through the opening in the frame side 4 and is equipped with spring 12 secured with nut 13. Each spring clamp is equipped with holder 14. Inside the base 1 there are two symmetrical beams 15 hung on axes 16. Each of the beams 15 is equipped at one end with arm 17 with movable mandrel 18 and in the side of the pallet base 1 there are two openings 19 and 20 symmetrically arranged in reference to the axis 16.
Inserting the mandrel 18 in one of the openings 19 or 20 stabilizes the beam 15 in one of two positions, in which the stabilising elements perpendicular to its two opposite surfaces can be utilised: the hooks 21 located at one surface or pins 22 located on the opposite surface. In the base 1 the recesses 23 are made for fork lift truck.

[0007] Depending of the type of transported vehicle bumpers, the frames 4 are set with use of mandrels 8 and the beam 15 with use of mandrels 18 in positions, in which the arrangement of the spring clamps 5, 6 on the top sides of the frames 4 and the stabilising elements 21, 22 on the top surfaces of the beams 15 enables contact free placing of the bumper, one after each other between the frames 4. The clamps 5 or 6 are intended for fixing particular bumpers in the places that are invisible after installation of bumper on the vehicle and the hooks 21 or pins 22 additionally stabilises the bumper using theirs installation openings. Number of the bumpers on the pallet is equal to the number of clamps on the frame side corresponding to this bumper size. Such design of the pallet provides optimal use of the transport space and simultaneously provides maximum protection against damages during transport.
