Abstract
Abstract A mattress-type gabion for ground stabilization is formed from a base sheet of wire mesh by providing the sheet with folds from spaced apart transverse ribs and having the panels of the folds tied together at transversely spaced locations along each rib. Cuts in the base sheet flanking each rib zone can define other folds which can be tied to the ribs when edge strips of the sheet are folded up, thereby forming stably upwardly open compartments which can be filled with ballast and then closed by a mesh cover.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
130 words
A mattress-type gabion for ground stabilization, comprising an elongated upwardly open compartmented base formed with a multiplicity of longitudinally separated base panels joined together by transversely extending ribs formed unitarily with said base panels from a single mesh sheet, each of said ribs being constituted as a fold having a pair of folded rib panels tied together at a plurality of locations separated along the respective fold and located close to the base panels connected by the respective rib, and side walls secured to said ribs by side wall strips separated from the respective rib by respective cuts parallel to a respective longitudinal edges of the sheet whereby edge folds are formed between each cut and the respective longitudinal edge, are turned inwardly and are tied to the respective rib.
Claim 2
Dependent Claim
130 words
A mattress-type gabion for ground stabilization, comprising an elongated upwardly open compartmented base formed with a multiplicity of longitudinally separated base panels joined together by transversely extending ribs formed unitarily with said base panels from a single mesh sheet, each of said ribs being constituted as a fold having a pair of folded rib panels tied together at a plurality of locations separated along the respective fold and located close to the base panels connected by the respective rib, and side walls secured to said ribs by side wall strips separated from the respective rib by respective cuts parallel to a respective longitudinal edges of the sheet whereby edge folds are formed between each cut and the respective longitudinal edge, are turned inwardly and are tied to the respective rib.
Claim 3
Dependent Claim
25 words
The mattress-type gabion defined in claim 1 wherein the rib panels of each rib are tied together by four spaced apart ties at said locations.
Claim 4
Dependent Claim
44 words
The mattress-type gabion defined in claim 1 further comprising; ballast forming compartments bounded by ribs, side walls and respective base panels; a mesh cover overlying said base; and means for securing said cover to said ribs and said side walls to close said compartments.
Claim 5
Independent Claim
158 words
A method of making a mattress-tupe gabion which comprises the steps of: forming an elongated mesh sheet having a pair of longitudinal edges and spaced apart rib zones defined between a pair of cuts parallel to said longitudinal edges and between each rib zone and a respective longitudinal edge; folding each rib zone to form a crease rising from a base panel whereby rib panels are formed below each crest for a multiplicity of ribs along said sheet; tying the rib panels of each rib together close to the respective base panels to limit spreading of said ribs; forming a side wall fold at each cut in said edge strip and folding said edge strips upwardly to define said walls and turning said side wall folds inwardly to flank the respective ribs; and tying the respective side wall folds to said ribs, thereby defining upwardly open compartments between opposing ribs, opposing side walls and a respective base panel.
Claim 6
Independent Claim
158 words
A method of making a mattress-tupe gabion which comprises the steps of: forming an elongated mesh sheet having a pair of longitudinal edges and spaced apart rib zones defined between a pair of cuts parallel to said longitudinal edges and between each rib zone and a respective longitudinal edge; folding each rib zone to form a crease rising from a base panel whereby rib panels are formed below each crest for a multiplicity of ribs along said sheet; tying the rib panels of each rib together close to the respective base panels to limit spreading of said ribs; forming a side wall fold at each cut in said edge strip and folding said edge strips upwardly to define said walls and turning said side wall folds inwardly to flank the respective ribs; and tying the respective side wall folds to said ribs, thereby defining upwardly open compartments between opposing ribs, opposing side walls and a respective base panel.
Claim 7
Dependent Claim
37 words
The method defined in claim 4, further comprises the steps of: filling said compartments with ballast; and closing said compartments with a mesh cover sheet and tying said cover sheet to said ribs and said side walls.
