Definitions

  • ABSTRACT A two-part knitting needle comprising a hook part formed with a stem and a hook, and a sliding latch part to reciprocate in a longitudinal guideway provided in said stem, the free end portion of the hook being terminated in an onrun portion to be engaged by said sliding latch part in order to prevent the latch from being deflected towards the interior of the hook part.
  • the present invention relates to a two-part knitting needle comprising a hook part formed with a stem and a hook, and a sliding latch part adapted to reciprocate in a longitudinal guideway provided in said stem.
  • a disadvantage encountered with the hitherto used knitting needles of the type consists in that as the sliding latch part is moved into its hook closing position, it tends to deviate, due to a drag exerted thereon by the knitted fabric, towards the interior of the hook part, i.'e. beyond its proper path pointing to the tip of the hook. Moreover after the closing of the hook part, if a proper contact between the sliding latch and the hook is unsufficiently ensured, the sliding latch may, during the knockover step, slide off from the hook tip and laterally deviate off the needle axis, due to a drag of the loop stitches suspended thereon. In the two cases the loop stitches may undesirably enter the interior of the hook part and fail to be knocked over so that a thread breakage or a damage of the needle may occur, which latter has to be replaced by another one.
  • the purpose of the present invention and the basic object of the same is to overcome the aforementioned disadvantages and to significantly improve the two-part knitting needle.
  • an improved two-part knitting needle comprising a hook part formed with a stem and a hook, and a sliding latch part adapted to reciprocate in a longitudinal guideway, such as a cavity or a channel, provided in said stem.
  • the needle being characterised in that the free end of the hook is provided with an onrun portion to be engaged by the sliding latch, which onrun portion merges into a guiding surface for guiding that 'part of the sliding latch which co-operates with the hook, said onrun portion being embodied by inwardly bending the free end of the hook.
  • the latch guiding surface is formed by a protuberance provided adjacent the free hook end. the latch being terminated in a channel.
  • the latch guiding surface is formed by channel provided in the free end portion of the hook. The length of the latch guiding surfaceon the free hook end portion equals to at least one fourth of the overall hook part length.
  • Another advantage of the invention resides in that, due to an improved guiding of the latch, it is possible to enlarge the inner space of the hook so that in case of e.g. the so-called blind lapping, a. plurality of ends can be simultaneously lapped into the hook, thus enabling relief patterns to be formed.
  • the height of the hook threat should correspond to or exceed 'the heights the hook inner space.
  • FIG. 1 is a somewhat schematic front elevational and partially sectional view of the two-part needle according to the invention
  • FIG. 2 is a sectional view taken along the line lI-Il in FIG. 1;
  • FIG. 3 is a view similar to FIG. 2, but'illustrating an other embodiment of the two-part needle.
  • the two-part needle comprises a hook part and a sliding latch part.
  • the hook part is formed with a stem 1 and a hook 2.
  • the stem 1 is provided with an axial cavity 3 to receive a reciprocatory shank 4 of the sliding latch part, the actual latch provided atthe free end of the shank 4 being indicated by reference numeral 5.
  • the free end portion 6 of the hook 2 is inwardly bent into the hook interior, thus forming an onrun portion 12 for the latch 5.
  • the top face of said hook free end portion is formed with a guiding surface designed to be engaged by that part of the latch Sdesigned to cooperate with the hook 2.
  • said guiding surface for the latch 5 is'formed with a protuberance or tongue 7 to be abutted by a channel or groove 8 the latch S is terminated in.
  • said guiding surface on the free end portion 6 of the hook 2 is formed by a notch or groove 9, the groove 9 receiving a tongue on the latch 5, as shown.
  • the hook 2 comprises further a throat ll of which height corresponds to or exceeds the heights of the inner space of the hook 2.
  • I I Y a In operation, in the lapping position of the needle the latch 5 is completely received in the cavity 30f the needle steml upon which a loop stitch formed in the preceding course is suspended. The thread is lapped into the open hook '2 by being slid into a first, outer thread guiding surface 14 thereon, the thread then slipping over protuberance 7 which constitutes a second guiding surface. In the next stage the hook part is displaced downwards into-the knock-over position; the latch 5 is simultaneously forced out of the cavity 3 in the stem 1 and the freshly formed .loop stitch 10 will slide thereonto as shown in FIG. 1.
  • the latch may deflect from its own path into the interior of the hook 2.
  • the latch 5 abuts the bent end portion of thehook 2 by which it is caused to take the correct course.
  • the latch 2 will bear upon the guiding surface of the hook 2 whereby the desirable mutual contact of the latch 5 and the hook 2 is ensured so that any lateral deflection of the latches 5 off the needle axis, due to the loop stitch drag, is prevented.
  • a two-part knitting needle comprising a hook part formed with a stem at its rear end and a hook with a free end at its forward end, and a sliding latch part formed with a rearwardly disposed shank which is arranged to reciprocate in a longitudinal guideway provided in said stem, the latch having a forward active portion which is adapted selectively to engage and cover the free end of said hook, the free end of the hook being provided with an onrun portion extending towards the interior of the hook and merging into a guiding surface for slidably guiding the active portion of the latch part thereover, said guiding surface being formed as a protuberance provided on the top of said one-fourth of the overall length of the hook part.
