Abstract
A knitting system 18 and a needle 1, which show greater stability and consume less power during the knitting process, include a bending portion 9 in which at least one recess 11 is arranged at at least one lateral surface 23 of the needle 1 and/or is formed in such a manner that a shaft offset S exists, in a peripheral direction U, between a working portion 10 of the needle 1 and a shank portion 8 of the needle 1.
Claims15
A knitting needle (1) comprising:
- a loop-forming element (2) arranged at a first end of the knitting needle (1), said first end pointing in a working direction (A),
- a shank portion (8), which is configured to be accommodated in a guiding groove (4) of a needle-guiding means (3), and is arranged at a second end of the knitting needle (1), said second end pointing in a direction opposite from the working direction,
- a working portion (10), which includes the loop-forming element (2) and which is configured to be accommodated in a verge groove (6) of the needle-guiding means (3), wherein the verge groove (6) is offset from the guiding groove (4) in the working direction and a peripheral direction (U) that is orthogonal to the working direction,
- a drive butt (16) of the shank portion (8) projecting from a surrounding portion of the shank portion in an elevational direction (H) orthogonal to the working direction and the peripheral direction,
- a bending portion (9), which is positioned in the working direction (A) between the shank portion (8) and the working portion (10),
- wherein in the bending portion (9) of the knitting needle (1), at least one recess (11) is arranged at at least one lateral surface (23) of the bending portion (9),
- wherein the at least one recess (11) either:
- points in the peripheral direction (U) and has a constant recess depth (22) of 10 μm to 100 μm along a majority of a length of the at least one recess, or
- points in the elevational direction (H) and has a constant recess depth (22) of 150 μm to 500 μm along a majority of a length of the at least one recess,
- wherein the shank portion (8) comprises a lower lateral surface and an upper lateral surface each extending between opposing lateral side surfaces of the shank portion, wherein the lower lateral surface extends in the working direction along a constant elevation between the drive butt (16) and the bending portion (9), and
- wherein a height dimension of the shank portion (8) measured in the elevational direction (H) between the lower lateral surface and the upper lateral surface decreases between the drive butt (16) and the bending portion (9) along the working direction.
8 more elements
A knitting system (18) comprising:
- at least one needle-guiding means (3), which has a base surface (12) pointing in an elevational direction (H),
- at least one guiding groove (4), which is arranged on the base surface (12) of the at least one needle-guiding means (3) and which extends substantially in a working direction (A), wherein said working direction (A) is orthogonal to the elevational direction (H),
- at least one verge groove (6), which is arranged on the base surface (12) of the at least one needle-guiding means (3) and is offset relative to the at least one guiding groove (4) in a peripheral direction (U) and the working direction (A), wherein said peripheral direction (U) is orthogonal to the working direction (A) and the elevational direction (H),
- at least one knitting needle (1) comprising, at a first end, which points in the working direction (A), a working portion (10) including a loop-forming element (2), and, at a second end, which points in a direction opposite from the working direction (A), a shank portion (8),
- a drive butt (16) of the shank portion (8) projecting from a surrounding portion of the shank portion in the elevational direction,
- wherein, between said shank portion (8) and said working portion (10), a bending portion (9) is positioned in which the at least one knitting needle (1) has a bend with directional components in the peripheral direction (U) and the working direction (A),
- wherein the working portion (10) of the at least one knitting needle (1) is accommodated in the at least one verge groove (6) and the shank portion (8) of the at least one knitting needle (1) is accommodated in the at least one guiding groove (4),
- wherein the shank portion (8) comprises a lower lateral surface and an upper lateral surface each extending between opposing lateral side surfaces of the shank portion, wherein the lower lateral surface extends in the working direction along a constant elevation between the drive butt (16) and the bending portion (9),
- wherein a height dimension of the shank portion (8) measured in the elevational direction (H) between the lower lateral surface and the upper lateral surface decreases between the drive butt (16) and the bending portion (9) along the working direction,
- wherein in the bending portion (9) of the at least one knitting needle (1), at least one recess (11) is arranged at at least one lateral surface (23) of the bending portion (9),
- wherein the at least one recess (11) either:
- points in the peripheral direction (U) and has a constant recess depth (22) of 10 μm to 100 μm along a majority of a length of the at least one recess, or
- points in the elevational direction (H), and has a constant recess depth (22) of 150 μm to 500 μm along a majority of a length of the at least one recess.
