BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to frameworks for collecting pieces of goods or parts, preferably of a varying, unsymmetrical, and irregular form, such as frozen animal carcasses and the like.
PRIOR ART
From PCT SE 80/oo587 a framelike device is known which is used for stabilizing a number of frozen animal carcasses composing a load unit. Said device exerts a stabilizing effect on the collection of parts or individual pieces, which are otherwise held together by a tightenable baglike enclosure.
Even if the complete load unit can be handled per se by means of a fork truck after having been turned over onto one side where a pair of reinforcement ribs are provided, such units are not able to be readily stacked, so if stacking is requested they are placed in specific frames or crates having rigid ends and vertical corner struts. The known frameworks for holding a load together are comparatively complicated to operate as they request that several manual operations be carried out before use.
The fact that the known framework arrangements cannot be stacked but need to be placed in special frames of baskets brings with it an undesired dependence on a specific type of storing and handling system. Besides the support jig wherein the wooden framework means and the bag enclosure is placed during the loading operation, specific spacing ribs and a specific turn-over equipment have to be mounted and in addition to this there are support frames of support baskets. The known framework means also requires, besides loading and handling personnel, access to personnel for mounting the fork handling ribs after that the bag enclosure has been tightened and straps applied.
OBJECT OF THE INVENTION
The invention has for its object to provide, starting from the known art, an improved framework means for goods which besides consuming a minimum of wood is simple to mount, easy to load, cover and strap and which has such a stability in loaded and ready condition that it is capable of carrying on top of it--without the support of auxiliary frames of baskets--at least two similarly loaded framework means.
SUMMARY OF THE INVENTION
The invention is based on cooperation between a framework or crate and strapping means enclosing the crate. As is well known woodwork has a good capacity of assuming compressive stresses if these are directed correctly in relation to the longitudinal fibre direction of the wood, and if the wood is stabilized laterally so that bending or buckling thereof is prevented. In wood structure it is also important that the junction points. i.e. in this case the corners, are arranged such that the connected unit becomes stable and controlled and so that the connection does not affect adversely the strength of the wood.
Transverse cross bars are secured by means of nailing or screwing to a pair of wooden rods forming a bottom frame, said cross bars serving as spacing means towards the basis or floor. At the ends of the rods upwardly open, socket like brackets are secured wherein the lower extremities of a pair of end pieces are inserted, the top extremities of said end pieces being inserted into similar socket like brackets on a pair of top rods. Hereby a closed frame or crate is formed where the extremities of the end pieces are firmly enclosed and guided by the sockets of the brackets. After putting the load inside the crate, which is stabilized during loading by means of external support members, straps are provided enclosing the crate and the load therein, parallel to the bottom frame of the crate as well as diagonally thereof. The crate and the strapping, in cooperation with the load which serves as holding-up means, create a lateral stabilizing of the uprights of the end pieces, making it possible to utilize maximally the ability of said uprights to carry compressive forces along the fibre direction.
Features characterizing the invention are disclosed in the accompanying claims.
