Automatic gripping device with extremely flexible hooks

摘要

An automatic gripping closure device comprising a first element with hooks comprising a first base band and at least two first hooks originating from the first band and placed in at least one row of first hooks (9), each first hook being delimited by two faces (11, 12) that are mutually opposed and transverse to the direction of the at least one row of first hooks and at least one coupling portion (13, 14) protruding laterally from the stem, preferably at the top of the latter, while extending in a direction transverse to the direction of the row, and a second element with hooks comprising a second base band and at least two second hooks originating from the second band and placed in at least one row.

1. A closure device comprising a first element having hooks and a second element having hooks, the hooks of the two elements being configured to engage with each other, the first element having hooks comprising a base strip and at least two parallel rows of hooks produced from the strip, the two rows being immediately adjacent rows without any other rows between said immediately adjacent rows, and the second element having hooks comprising a base strip and at least one row of hooks produced from the strip, wherein:
each hook of the first element is delimited over the entire height thereof, from the base strip as far as a top thereof, the top being defined as the surface of the hook further away from the base strip, by two mutually opposed planar surfaces which are transverse relative to the direction of the two rows of hooks; each hook of the first element comprises two right and left projection engagement portions which project laterally from a shank, extending in a transverse direction relative to the direction of the rows and in opposite right and left directions and that are configured to engage with the hooks of the second element; each hook of the first element has a thickness corresponding to the distance in the direction of the two immediately adjacent rows of hooks between the two mutually opposed, planar surfaces in the region of the base strip; a spacing distance between two successive hooks of each of the at least two immediately adjacent rows of the first element, measured in the region of the base strip in the direction of the two rows, which defines a longitudinal direction, is greater than the thickness of each hook; the at least two immediately adjacent rows of the first element are spaced-apart from each other by a distance such that, when hooks of the at least one row of the second element are inserted therebetween with their heads orientated in opposite to the heads of the hooks of the first element, an engagement portion of at least a first hook of the second element is adapted to become engaged with one of the right or left projection engagement portion of one hook from one row of the first element and another engagement portion of said at least first hook or an engagement portion of a second hook of said at least one row of the second element is adapted to become engaged with another one of the right or left projection engagement portion of one hook from another row of the first element, immediately adjacent to said one row.
