Description

Technical field

The invention relates to a pallet for storing and transporting articles which are stacked in at least two layers separated from each other by a bottom. The pallet consists of a base part having an outer border and a loading surface for objects or an intermediate floor. At least two uprights are arranged vertically on the frame, with one notch being formed at the upper end of each upright and a vertical guide below it. In each post, a tilting post is displaceably displaced for displacement from an operating position by sliding upward into an upright intermediate position and from there by tilting it to a horizontal rest position. On each hinge post, a lower protrusion is provided for continuous engagement with the guide and an upper protrusion for engagement with the notch to lock the vertically oriented hinge pillars in the operating position.

BACKGROUND OF THE INVENTION

The known pallets are designed as flat panels of wood, plastic or preferably of metal, which make it possible to assemble a number of homogeneous or varied goods into a cargo unit. These known pallets have a rectangular base piece, usually having dimensions of 800 x 1000 mm or 1000 x 1200 mm. Flat pallets are also known, on whose narrow sides upright yokes are fastened. In other known pallets, an upright column, also called a column, is formed at the four corners of the rectangular base profile and is formed by a steel angle. On such pallets, objects can be arranged in multiple layers and separated by inserted days. The intermediate bottoms secure the posts or columns against lateral displacement, the intermediate bottoms being generally shaped to secure objects to be transported against displacement.

SUMMARY OF THE INVENTION

These drawbacks are largely overcome by a pallet for storing and transporting articles which are stacked in at least two layers separated from each other by a bottom consisting of a base having an outer border and a bed for objects or an intermediate floor, vertically arranged on the border. at least two posts, wherein one notch is formed at the top end of each post and a vertical guide below it, wherein each post has a tiltable post for displacement from the operating position by sliding up to an upright position and thereafter tilting to a horizontal rest position; a lower projection for continuous engagement with the guide and an upper projection for engaging a notch for locking the vertically oriented tilt columns in an operative position, the support being always attached to the base column posts, which is located at a height above the loading surface to support the hinged posts in their horizontal resting position on the respective support. The lower end of the guide is located below the abutment and its upper end is located above the height of the abutment upwards.

According to a preferred embodiment, the height of the abutment above the loading surface corresponds to the height of the stacked intermediate days without transportable objects, without exceeding this height.

According to a further preferred embodiment, the supports are mounted on one of the posts.

According to a further advantageous embodiment, the base part has four corners on which one post stands. The columns are connected in pairs to each other by the lower crossbar and the respective tilting columns are connected to each other by the upper crossbar.

The main advantage of the proposed solution is that if the pallet is used without transported objects, for example for return transport after unloading, it can be stacked and stowed at standstill with space saving, yet ensures a secure hold for the insertion days, while allowing the pallet to be stacked at least two layers separated by bottom.

Overview of the drawings

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a front elevation of the pallet; FIG. 2 is a plan view of the pallet; FIG. 3 is a side elevation of the pallet; FIG. .

DETAILED DESCRIPTION OF THE INVENTION

The pallet shown has a base member 10 with an outer border 12 formed by a rectangular frame of a horizontal U-profile with arms turned outwards. Four blocks 14 are fastened to the underside of the frame 12, which provide the necessary clearance between them for engaging a forklift or the like. Two parallel longitudinal stiffeners 16 as well as a plurality of transverse stiffeners 25 18 are arranged perpendicular thereto, which together form a horizontal loading surface 20 for transporting objects or for an intermediate floor.

On each of the four corners of the border 12, one column 22 of the base part 10 is formed, consisting of an angular profile with an outwardly directed apex welded to the border 12 as well as to the longitudinal reinforcement 16 and the transverse reinforcement 18 and held in addition by a welded triangular reinforcing plate. . Each of the posts 22 is associated with a support 24 formed at a height h above the loading surface 20 and formed by a horizontal pin welded to the arm of the respective post 22 and to the upper corner of the respective reinforcing plate. The supports 24 are arranged in pairs near the narrow side of the generally rectangular base member 10 facing each other and their height h above the loading surface 20 is determined so that it can be stacked on the loading surface 20 for several insertions without transported objects. exceeded, i.e., the height h of the support 24 above the loading surface 20 corresponds to the height of the stacked intermediate days without transportable objects, without exceeding this height h. For example, four profiled intermediate bottoms 40 are used to transport the brake drums erected in three layers one above the other, which can be folded into a stack with a total height of 60 mm for return. In this case, the height h of the abutments 24 above the loading surface 20 is at least 60 mm, preferably 65-70 mm.

Each of the posts 22 has at its upper end in one of the legs facing away from the adjacent post 22 a notch 26 in the form of a slot open from above. Under the notch 26, a guide 28 is formed in the same arm in the form of a substantially vertically oriented longitudinal bore having an arc formed at the lower end toward the upper end of the angle profile of the respective post 22. The lower end of the guide 28 is positioned at approximately h / 2 and the upper end is located approximately 2h above the loading surface 20. The upper ends of the mating pairs of pillars 22 are joined together by a welded lower beam 30.

In each post 22 there is a hinged post 32, which in the illustrated embodiment is formed of a square tube, the two sides of which lie on the inner side of one arm of the respective post 22. The hinged posts 32 stand vertically in the operating position shown in which the upper ends are pairs of adjacent hinged pillars 32 joined together by an upper beam 34,

The folding pillars 32 are shown in abbreviated form in Figs. 1 and 3 and may have a height greater than the width of the base member 10, but should be at least slightly smaller than its length. .

An upper protrusion 36 and a lower protrusion 38 are formed on each of the four hinged posts 32, both protruding laterally. The upper protrusion 36 is in the operating position inserted into the notch 26 of the respective post 22 and the lower protrusion 38 still engages the respective guide 28. In the illustrated embodiment, the protrusions 36, 38, as seen in FIGS. The upper protrusion 36 is welded and the lower protrusion 38 is provided with a threaded pin 40 and is clamped firmly to the respective foldable pillar 32 by means of a washer 42 and nut 44.

Each pair of hinged pillars 32, in the operating position together with the respective upper beam 34, forms a vertical part of the side wall. Between the two vertical wall sections thus formed, objects can be placed, for example stacking the brake drums into several layers, each resting on one inserted bottom and the top is covered by the additionally inserted bottom. The stack thus formed is usually held together by tensioning belts or similar parts and is fastened to a pallet.

After the articles have been transported and unloaded, the inserted bottoms are space-saving and deposited on the mattress platform 20. Then, the upper crossbars 34 are pushed or pushed up, each upper crossbeam 34 carrying both respective hinged pillars 32 with them and releasing their upper protuberances 36 therefrom. For this purpose, only one stroke movement is required, the size of which corresponds to two or three times the diameter of the upper protrusion 36, the lower protrusions 38 being displaced in their guide 28 by a corresponding small path upwards. Now, the hinge pillars 32 can be folded in pairs inwards.

In the absence of abutments 24, the hinge pillars 32 would tend to drop again at the beginning of the tilting as soon as the upper protuberances 38 are released from the pillars 22 so that the lower protuberances 38 rest against the lower end of the respective guide 28 and form at this point. This would, however, involve the danger of downwardly tilting hinged pillars 32 creating considerable gravitational forces on the stacked intermediate bottoms and thereby damaging them. However, the abutments 24 support the hinge pillars 32 as they are tilted so that each pair of hinge pillars 32 is folded around a common axis of a pair of abutments 24, with the lower protuberances 38 sliding up in the guides 28 so that be compressed. The folding pillars 32 are folded down over the horizontal position until the upper crossbars 34 finally touch the intervening bottoms and hold them without placing an excessive load on them.
