In particular, this invention relates to racks which can be used for storage of pallet loads using vertical height of the storage area without loss of aisle space. The rack in accordance with this invention is mobile in construction and collapsible for saving space while empty. Still particularly, the rack can be stored when not in use in a collapsed state and also can be moved from one place to another manually or by forklift. ID particular, this invention relates to stacking devices in the form of collapsible mobile racks. Still particularly, this invention relates to racks for storage to be used in storage areas for stacking pallets, typically in cold storages. Pallets are generally stored on a storage floor area also referred to as pallet space temporarily and are moved around by fork lift trucks. In the case of pallets which bear soft items it is hitherto not possible to stock pallets one on top of the other in a larger vertical stack. Depending on the softness of the packets placed on the pallet, it may be possible to load one or more pallets on top of another. Referred to as pallet space for two. However in most cases the weakness of the packages on the pallet prevent vertical stacking of pallets on top of another. Generally about 30% of storage space is lost when drive in vertical storage systems are installed in a given space. This invention envisages a rack for vertical stacking of pallets one on top of another. According to this invention there is provided a rack adapted to form storage means above a pallet stack, said rack consisting of column element pairs secured to beam elements, the column element pairs being secured to each other by means of collapsible means which permit the pairs of column elements to be variably displaced from a spaced apart configuration to a collapsed so that in a spaced apart configuration the rack straddle is adapted to a pallet stack located in the space defined by the column element pairs and the beam elements are able to support a second set of pallet stacks there above without loading the pallet stack located in the space defined in the column elements and in the collapsed configuration the rack is transportable for storage. The invention will now be described with reference to the DRAWINGS accompanying the provisional specification, in which Figure 1 shows a front view of the rack in accordance with this invention; Figure 2 shows a side view of the rack; and Figure 3 shows a front isometric view of the rack. Referring to the drawings, in the figures, according to this invention there is provided a rack generally indicated by the reference numeral 10, consisting of column element pairs 12 secured to beam elements 14, the column element pairs 12 being secured to each other by means of collapsible means 20 which permit the pairs of column elements to be variably displaced from a spaced apart configuration to a collapsed so that in a spaced apart configuration the rack 10 straddles a pallet stack [not shown] located in the space defined by the column element pairs and the beam elements 14 are able to support a second set of pallet stacks [not shown] thereabove without loading the pallet stack located in the space defined in the column elements and in the collapsed configuration the rack is transportable for storage. The column elements are typically C sections with fitted inside collars. It is envisaged that a plurality of such racks will be located in a storage area. One pair of column elements are provided with support members of the type seen in the figures and marked as reference numeral 16 which prevent a pallet stack straddled by the rack from tipping backwards. Also it is envisaged that a plurality of racks 10 can be placed adjacent to one another in series so that pallets will be located with the space defined by the column pairs and pallet stacks will be mounted on the beam elements straddling the column elements. It may be possible to have an additional pair of column and beam elements mounted on the first rack so that storage may be provided on an additional deck above the first. As seen in the figures the racks are displaceable and therefore wheels, castors or rollers 18 are provided at the foot of each column to permit displacement of the racks. The columns and beam elements can be of any suitable material typically metal. Example A mobile storage rack in accordance with this invention was made with formed sections basically 'C sections with added inside collars of the following specifications: 1. four columns in a typical formed section out of 14 SWG M.S. sheet of size 110mm x 50mm x 1805mm, basically a C section with added inside collar of 18mm. 2. Two columns welded at one end to form a U shape by a rectangular pipe of size 100mm x 75 mm of length 1490 mm. 3. Two no. of formed channel sections of size 60mm x 25mm x 1680 long were used to form Scissor pivoted at the center. 4. The two scissors were used to interconnect the two U shaped frames on two sides in such a way that the top end of the scissor arms were pivoted to each U frame and the other arm ends were fitted with Teflon rollers of size 50mm dia x25 mm. An additional fixed stopper was bolted in the column section to limit the frame opening. 5. Unequal angles of size 30mm x 20mm x 400mm long and 50mm x 20 x 400mm long were fabricated out of 16 gauge M.S.sheet and were welded at the bottom of each of the columns to place the scissors in place and facilitate the sliding motion when required. 6. Formed Typical section rolled out of 14 gauge M.S'.sheet of size 110mm x 50 mm of length 1923 mm and 1380 mm were bolted to rear U frame to provide the required stability in a cross and horizontal position. 7. A pair of swivel castor wheels of size 125mm dia x 50 mm was bolted with the front U frame base and the fixed castors of the same size were bolted to the rear U frame base for easy movement when in the unloaded condition 8. A locking channel was pivoted at the center to the rear frame column on the sides to provide locking in laden as well as unladen condition. • The assembly making use of above subparts makes it a Mobile Flexible Rack with overall dimensions of 1090mm x 1490mm x 2050mm (LxBxH) in open condition and 1090 mmx 1490mm x 580mm (LxBxH) in closed position. • The rack in open position can take 2000 Kgs. of load either on single pallet or on two pallets (One stacked over other). The typical Dimensions are given for a particular height and the size of the pallet used. The variants can be with different pallet sizes and different height or different loads as per the product stacked on the pallet. Other dimensional and fabrication details can vary depending upon the nature of design to sustain a load of 2000 Kgs. Typical use in an operative configuration : First move the folded rack to the desired storage location with open U frame with the swivel wheel facing the loading position. One /Two pallet loads admeasuring the available height of 1850 mm Max. are placed on the floor within the close frame on the floor. Now the rack assembly is opened and locked in position. At this position the rack stays stable with a load of 2000 Kgs. placed on top. Thus the vertical storage space is utilized without losing the floor space in aisles and thus preventing the product damage when stacked one above the other. The rack in accordance with this invention can be used anywhere not requiring any supports or guide ways for vertical stacking. The basic invention and an example has been described herein but should not in any manner be deemed to be restrictive. Although the invention has been described in terms of particular embodiments and applications, one of ordinary skill in the art, in light of this teaching, can generate additional embodiments and modifications without departing from the spirit of or exceeding the scope of the claimed invention. Accordingly, it is to be understood that the drawings and descriptions herein are proffered by way of example to facilitate comprehension of the invention and should not be construed to limit the scope thereof.
