Abstract

Abstract A handicraft tool for knotting cut piles or loops one by one to each of filaments of a separately prepared meshed basic sheet material to produce piled article such as tapestry, rug, carpet and the like, which tool has a sleeve capable of carrying one or more cut piles and a pair of resilient hook levers. The hook levers are reciprocated by an actuation button from an extended position, where the tips of the two levers are separated so as to receive the piles, to a retracted position, where the lever tips resiliently engage with each other to be closed so as to hold the pile and facilitate the knotting of the pile to the basic material. A grooved bobbin-like cassette carrying yarn wound thereon may be selectively mounted on the tool, and the wound yarn may be severed along a groove of the cassette, so that a plurality of cut yarn piles may be carried by the sleeve of the tool upon removal of the cassette therefrom.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 248 words
A handicraft tool for forming a piled sheet article by knotting a plurality of cut loops of yarn one by one at the bent root portion thereof to each of filaments forming a plurality of meshes of a meshed sheet base, comprising an elongated hollow body member to be gripped, a thin sleeve connected with said body member at the forward end thereof so as to produce opposite shoulders at the body member forward end for holding a yarn cut loop with the bent root thereof abutting on the lower surface of said sleeve and with the legs of said loop each extending upwardly and abutting on each of said shoulders, said sleeve being of such diameter as allowing same to pass through each of said meshes, a reciprocatingly movable member disposed in said body member so as to be manually moved relative thereto between the forwarded position and the retracted position, and the pair of resilient hook levers arranged in said sleeve extending over a length thereof, said hook levers having their inner ends connected together with said reciprocatingly movable member and the outer free ends designed to be normally separated from each other to form an open hook slightly protruded out of said sleeve when said reciprocatingly movable member is in said forwarded position but forcingly engaged with each other to produce the closed hook against the elasticity due to being pulled into the sleeve when said reciprocatingly movable member is brought into said retracted position.
Claim 2
Dependent Claim 248 words
A handicraft tool for forming a piled sheet article by knotting a plurality of cut loops of yarn one by one at the bent root portion thereof to each of filaments forming a plurality of meshes of a meshed sheet base, comprising an elongated hollow body member to be gripped, a thin sleeve connected with said body member at the forward end thereof so as to produce opposite shoulders at the body member forward end for holding a yarn cut loop with the bent root thereof abutting on the lower surface of said sleeve and with the legs of said loop each extending upwardly and abutting on each of said shoulders, said sleeve being of such diameter as allowing same to pass through each of said meshes, a reciprocatingly movable member disposed in said body member so as to be manually moved relative thereto between the forwarded position and the retracted position, and the pair of resilient hook levers arranged in said sleeve extending over a length thereof, said hook levers having their inner ends connected together with said reciprocatingly movable member and the outer free ends designed to be normally separated from each other to form an open hook slightly protruded out of said sleeve when said reciprocatingly movable member is in said forwarded position but forcingly engaged with each other to produce the closed hook against the elasticity due to being pulled into the sleeve when said reciprocatingly movable member is brought into said retracted position.
Claim 3
Dependent Claim 110 words
A handicraft tool according to claim 1, in which there are formed a pair of longitudinally elongated grooves in said body member at each of said opposite shoulders so that the body member is divided at the forward end area thereof into a central longitudinally elongated portion to form a substantial part of said elongated sleeve and two longitudinally elongated side portions each defining said grooves between said central elongated portion, whereby one or more yarn cut loops may be held with each bent root thereof abutting on the lower surface of said central elongated portion and with the legs of said loop extending upwardly through each of said grooves.
Claim 4
Dependent Claim 100 words
A handicraft tool according to claim 2, in which a separate bobbin cassette around which a length of yarn is wound for forming a plurality of successive coils, is adapted to be removably mounted on said body member along said central elongated portion so that when said wound yarn is cut along the upper coiled portions and said bobbin cassette is removed, a plurality of cut loops may be left with each bent root thereof abutting on the lower surface of said central elongated portion and with the legs of said each loop extending upward through each of said grooves.
Claim 5
Dependent Claim 72 words
A handicraft tool according to said claim 3, in which said cassette is of substantially rectangular cross section and has a top groove and a bottom groove each longitudinally extending so that said wound yarn may be facilitatingly cut by inserting a cutter blade along said top longitudinal groove and said bobbin cassette may be facilitatingly mounted on said body member with said bottom longitudinal groove sliding along said central elongated portion.
Claim 6
Dependent Claim 22 words
A handicraft tool according to claim 1, which further comprises means for manually actuating said reciprocatingly movable member outside said body member.
Claim 7
Dependent Claim 58 words
A handicraft tool according to claim 5, in which said manual actuation means is a button disposed out of said body member and adapted to be longitudinally moved along a slit formed in the casing wall of the body member so as to drive said reciprocatingly movable member connected with said button between the forwarded and retracted positions.
Claim 8
Dependent Claim 92 words
A handicraft tool according to claim 5, in which said manual actuation means is a swingable sector pivoted at the center thereof on the casing wall of the body member so as to be angularly moved between the normal protruded position and the forcingly pushed retracted position, said sector being mechanically connected with said reciprocatingly movable member in such a way that when said sector is manually pushed against the force of a spring means down into the retracted position, said reciprocatingly movable member is longitudinally moved into the retracted position thereof.
