Definitions

  • the present invention relates to a stacking system for long members, in particular for scaffolding tubes.
  • Such a system is not really suitable for scaffolding tubes, because predetermined numbers of them and differing length cannot readily be kept separate.
  • the object of the present invention is to provide an improved stacking system
  • a system for stacking elongate members on a base comprising:
  • each pair of uprights having:
  • the mechanism comprising: o a latch to retain the bridge piece in its folded-up position, leaving open the gap for loading of the members and • a trip to release the bridge piece on loading of the members into the gap below the level of the pivot, whereupon the bridge piece deploys downwards under gravity for loading of secondary elongate members onto it and o the latch being adapted to latch the bridge piece when pivoted up on lifting of the members from below it.
  • the uprights can include individual feet for holding them upright, particularly where the base is a concrete storage platform.
  • the uprights in each pair can be interconnected by a crosspiece to which the uprights are attached for holding them upright, the crosspiece extending laterally of the stacking orientation.
  • the crosspieces can be adapted to be clamped to a side rave.
  • the feet and/or crosspieces can be adapted to be bolted to the base.
  • the crosspieces Preferably, at least some of the crosspieces have the uprights of more than one pair thereof attached to them. Again, at least some of the crosspieces having more than one pair of uprights can be cranked to position one pair differently longitudinally from another pair.
  • the feet or crosspieces can include stabilising feet extending longitudinally of the stacking orientation.
  • each pair of uprights has a second bridge piece, pivot, support point and latch and release mechanism above the first for tertiary elongate members.
  • the pivot for the first bridge piece will be on one upright in each pair and that for the second bridge piece will be provided on the other.
  • the latch can be magnetic, and in particular a pair of complementary magnets, one secured to the bridge piece at or close to its distal end and the other secured at a corresponding position on the upright having the pivot of the crosspiece.
  • the trip can be a lever extending from the bridge piece towards the other upright, into the path of elongate members being stacked between the uprights.
  • the latch can be is a sear mechanism provided at the pivot the trip being a lever extending into the path of elongate members being loaded and adapted to release the sear mechanism.
  • the uprights are hollow and slotted at sides facing each other, the bridge piece being received through the slot in the one when folded up and extending from the slot in the one, across and into the slot in the other with its distal end when deployed.
  • one or other of the uprights in each pair is provided with a gap closure member, pivotable at the top of its upright and to extend to the top of the other upright for stacking of materials on top.
  • the gap closure member is a channel member having its web on the outside of its upright and having longitudinal slots in its flanges, whereby it is slidable up the upright and pivotable across to the other upright.
  • Another feature of the preferred embodiment is a head board having a liftable and pivotable panel arranged to be laid across the tops of at least some of the uprights.
  • the trip of the release mechanism may be positioned for actuation by an operator.
  • the release mechanism can include a load sensing mechanism, whereby the weight of a load on a bridge piece or a crosspiece or indeed the base will trigger release of the latch.
  • Figure 1 is a perspective view of a stacking system of the invention
  • Figure 2 is a similar perspective view with scaffolding tubes stacked in the system
  • Figure 3 is a plan view of the system and stacked tubes;
  • Figure 4 is an end view of selected ones of the uprights of the system, showing details of bridging pieces;
  • Figure 5 is a similar view showing a bridging channel deployed across the uprights;
  • Figure 6 is a side view of the end o f the system, showing a folding head board deployed;
  • Figure 7 is a sectional view of a pair of uprights according to the invention with a single bridge piece;
  • Figure 8 is a cross-sectional view o f a pair of uprights according to the invention having two bridge pieces and in use;
  • Figure 9 is a cross sectional view o f Figure 10 is a top view of a lorry pro vided with the stacking system of the invention in use with scaffold tubes;
  • Figure 5 is a top view of a second lorry provided with the stacking system of the invention and a crane and grab for moving the tubes.
  • a stacking system 1 for tubes is shown supported on a base 2.
  • a base For the purposes of the description with reference to Figures 1 to 6, the nature of the base is immaterial, it could be either a vehicle bed or a stationary bed. The vehicle would be used for transporting the tubes for use on a construction site; whilst the stationary bed would be used for storage of the tubes between construction use.
  • the system includes eleven pairs of right and left uprights 11,12. They are supported upright by crosspieces 14,15,16, there being two straight crosspieces 14 and two cranked crosspieces 15,16.
  • the straight crosspieces have three pairs of uprights, whilst the crosspiece 15 has two pairs and the crosspiece 16 has three pairs.
  • This particular arrangement allows five differing lengths of tubes Tl — T5 of successively longer length to be stacked.
  • the length of the tubes is parallel to an axis L.
  • the crosspieces are of rectangular section tubular steel, typically 120 x 80 x 8mm. At each upright position, they have sockets 17 formed by welding a short length of square section tubular steel through from top to bottom. The uprights fit into the socket sockets and are held upright.
  • the crosspieces can be bolted to the base via welded-on feet 3 extending in the direction of the axis L, clamped via clamps 4 engaging in the ends of the crosspieces and around an edge of base or otherwise secured to the base.
  • the uprights are square section tubular steel, typically 80 x 80 x 5mm, with slots 18 in their faces facing each other in their pairs.
  • the slots extend from close above their lower ends to a little short of their upper ends, which are bevelled inwards 19 in the pairs.
  • they In their three tier form, shown in Figures 4,5,6, they have two cross pins 20 spaced at approximately 1/3 and 2/3rds height up them.
  • L-shaped bridge pieces 21 of steel plate are pivoted on one upper cross-pin and one lower cross-pin in each pair of uprights.
  • the long limb 22 of the L is provided at its distal end 23 with a magnet 24 on its face which abuts to the inside face 25 of its upright opposite from the slotted face.
  • the inside face itself is provided with a complementary magnet 26.
  • a pack of tubes is lowered between the chosen pairs of uprights. As they strike the short limbs, the bridge pieces are released and bridge the gap between the uprights that the tubes have just been lowered into. Thus a second pack can be stacked on the bridge pieces above the first. Where two pivots are provided, a third pack can stacked on the second bridging pieces. When the packs are unloaded, the bridging pieces are lifted or folded back to be held by their magnets.
  • the bevelled end of one of the uprights in each pair has a peg 28 welded across it.
  • the upright has a channel member 29 encasing it on all three sides except for its slotted side.
  • the channel has a slot 30 in each of its flanges 31, with the peg received in the slot.
  • the web 32 of the flange has an eye 33.
  • a head board 41 is provided with a liftable panel 42.
  • the board is provided with pegs 43 analogous to the pegs 28 and the panel is provided with slotted sides 44.
  • the panel has a handle 45, by which it can be lifted and swung down onto end ones on the bridging channels 29. It then becomes a platform on which materials can be stored such as scaffolding fittings in stillages.
  • the system can be mounted on a lorry equipped with a crane with a grab.
  • the crane can be used not only for stacking the tubes in the system, but also for manoeuvring the bridging channels and the liftable panel.
  • FIG. 7 to 11 there is a pair of uprights 110, 112 according to the present invention.
  • the two uprights 110, 112 define therebetween a space 114 into which elongate items can be placed.
  • a foot 116 Near the base of the first upright 110 is provided a foot 116, for a latch and release mechanism 115.
  • This is connected by a lever 118 to a pin 120, the pin having a detent or sear 122 for interlocking with a notched ring 124.
  • Depression of the actuator 116 releases the detent 122 from the ring 124, allowing the ring 124 to turn and lower a bridge piece 126.
  • the bridge piece closes the channel 114 between the two uprights 110, 112, and sits on a bar 128 on the second upright 112.
  • the position of the bridge piece 126 after actuation is shown in dotted lines.
  • the arm is lifted into the upright position. The can be achieved by removal of the elongate items out of the channel, moving the arm into the uprights position.
  • FIG 8 shows the stacking system of the invention in use.

Abstract

L'invention concerne un système d'empilement (1) comprenant onze paires de montants droits et gauches (11,12) maintenus verticaux par des traverses (14,15,16), deux d'entre elles (14) étant droites et deux autres (15,16) étant coudées. Les traverses droites sont constituées de trois paires de montants, la traverse (15) étant constituée de deux paires de montants et la traverse (16) de trois paires. Cet agencement particulier permet d'utiliser cinq longueurs de tubes T1-T5 différentes à empiler. La longueur des tubes est parallèle à un axe L. Les montants constitués d'acier tubulaire à section carrée sont équipés de fentes (18) ménagées dans les faces de chaque paire opposées les unes aux autres. Les fentes s'étendent un peu au-dessus des extrémités inférieures des montants à un peu en-dessous de leurs extrémités supérieures et sont biseautées vers l'intérieur (19) des paires. Des pièces (21) de plaques d'acier en L formant un pont pivotent sur un croisillon supérieur et un croisillon inférieur de chaque paire de montants. La partie allongée (22) du L est équipée, au niveau de son extrémité distale (23), d'un aimant (24) installé sur la face venant en about avec la face intérieure (25) du montant opposé à la face à fente. La face intérieure est elle-même dotée d'un aimant complémentaire (26). Lorsque la partie allongée du L pivote vers le haut à l'intérieur du montant, les aimants sont maintenus en position. Ceux-ci peuvent pivoter lorsque la partie courte (27) du L entraîne la rupture de l'attraction magnétique. La partie allongée du L forme ensuite un pont dans l'espace entre les montants, son extrémité distale étant introduite dans la fente du montant opposé. Elle est supportée sur un boulon transversal du montant à la même hauteur que le boulon transversal pivotant de l'autre montant. Lorsqu'on utilise le système d'empilement, les parties allongées ou les parties formant un pont sont maintenues par leurs aimants, une pile de tubes est abaissée entre les paires de montants choisis. Lorsqu'elles viennent frapper les parties courtes, les parties formant un pont sont libérées et un pont est établit dans l'espace entre les montants entre lesquels les tubes ont été abaissés. Puis, une seconde pile de tubes peut être empilée sur les parties de pont au-dessus de la première pile. Lorsque deux pivots sont installés, une troisième pile de tubes peut être empilée sur les secondes parties de pont. Lorsque les piles sont déchargés, les parties de pont sont levées ou repliées afin d'être maintenues par leurs aimants.
