Description

  The present invention relates to a handicraft crochet and a crochet grip body. Specifically, the present invention relates to a crochet that can prevent slipping during use and can perform knitting work with a sense of unity with fingers.

  2. Description of the Related Art Conventionally, in hand knitting work, a crochet needle is often used which is formed entirely of a rod-like metal and has a hook portion for hooking a knitting yarn at the tip.

  Since the metal crochet is formed thinner than fingers, it is slippery and difficult to hold stably with fingers. In addition, since the gripping force of fingers cannot be effectively applied to the crochet, there has been a problem that fingers are easily fatigued when knitting work is performed for a long time.

  In order to alleviate the above problems, a grip body made of a flexible resin material is provided at a position where the finger is gripped with a finger and is configured to be easily gripped.

Utility model registration No. 130850

  In the invention described in the above-mentioned patent document, a grip body is provided on the base end side including a portion to be gripped with a finger in a metal needle body provided with a hook portion at the tip.

  In order to alleviate the feeling of fatigue in hand knitting work using a crochet, the gripping force can be effectively applied to the crochet so that the crochet can be gripped with as little force as possible. It is important to be able to operate with a sense of unity.

  In the invention described in the above-mentioned patent document, since the grip body formed thicker than the needle body is provided in the portion to be gripped with fingers, it is easy to grip, and the force necessary for gripping is reduced to some extent. be able to. However, in the crochet provided with the grip body as described above, since the cross section of the grip body is larger than the needle body, it is easy to grip with a small force, but it becomes difficult to scoop the knitting yarn in the knitting work, There was a problem that the sense of unity was reduced.

  The inventor of the present invention is that the above-mentioned sense of unity decreases because the grip body is provided, so that the position of the key part provided at the tip of the needle body with respect to the finger is displaced from the position of the key part of the conventional crochet. I found out that is the cause.

  That is, by providing the grip body, it is possible to grip with a finger a position that is separated from the surface of the needle body by the thickness of the grip body, as compared with the case where the work is performed by directly gripping a conventional rod-shaped needle body. Become. For this reason, the distance and angle from the above-mentioned key part are also different, and depending on the gripping position, it may be difficult to scoop the knitting yarn with the key part, or the sense of unity between fingers and crochet may be reduced. It was.

  This invention solves the said subject and makes it a subject to provide the crochet which not only is easy to hold but can perform knitting work with a finger and a sense of unity.

The crochet according to the present invention is a crochet provided with a crook provided at the tip and having a linear bar-like needle body having a circular cross section and a grip body covering the base end side so as to project the tip of the needle body. The grip body includes a base end portion having a circular cross section, and a gripping portion provided on the distal end side of the base end portion and having a recess formed on one side of the outer periphery, The hook portion is formed on the side where the hook portion is provided, and is formed in a cross-sectional arc shape in which the central portion in the longitudinal direction is recessed, and the shaft tip of the needle body is It is provided by being displaced to the side opposite to the side where the concave portion is provided, and the radial outer surface of the hooking portion is parallel to the axis of the base end portion and extends radially from the extension line passing through the bottom surface position of the concave portion. Radius from the extended line of the base end surface on the outer side and the side where the recess is provided It is configured to be located on the inner side in the direction, and bulges outwardly in the radial direction from the surface of the base end portion on the opposite side across the shaft of the base end portion and the side where the concave portion is provided A second bulging portion that protrudes radially outward from the surface of the base end portion on both side edges in a direction orthogonal to the axis of the base end portion on the bottom surface of the recess. A bulging portion is provided.

  As a result of trial and error, the inventor of the present invention has found that the above-described disadvantage can be avoided by providing the position of the hook portion at a predetermined position with respect to the position held by the thumb. That is, when performing the hand knitting operation, the thumb is most involved in the movement of the hooking portion of the crochet, and the knitting portion is set to a predetermined position on the basis of the thumb position. It has been found that the thread becomes easy to scoop and a sense of unity between the crochet and fingers can be obtained.

  The conventional crochet grip body is not provided with a portion for positioning the thumb, and is configured so that the thumb can be attached and held at a position according to the user's preference. For this reason, by providing the grip body, not only the thumb is separated from the needle body, but also the axial position of the thumb is not determined. For this reason, the position of the key part with respect to the thumb is not fixed, and it becomes difficult to scoop the knitting yarn, and the sense of unity between the crochet and the finger is lowered.

  In addition, in order to obtain a sense of unity between the crochet and the finger, the inventor of the present invention is on an extension line in the axial direction (axial direction of the grip body) from the portion gripped by the thumb (surface of the grip body). The present inventors have found that it is preferable to set the hook portion of the hook portion.

In the present invention, a grip body is provided that includes a base end portion and a gripping portion that is provided on the front end side of the base end portion and has a recess formed on one side of the outer periphery. Although the cross-sectional form of the base end is not particularly limited, it is preferably formed in a rod shape in which the circular cross section does not change. In the present invention, the base end portion is used as a reference for the size and form of the gripping portion. The concave portion is formed on the side where the hook portion of the hook portion is provided and is formed in a cross-sectional arc shape in which the central portion in the longitudinal direction is recessed. For this reason, it is possible to determine the axial position and the circumferential position of the thumb by attaching the thumb to the recess and gripping the grip portion. Moreover, since the said recessed part is formed so that the surrounding surface of a grip body may be notched, the holding position of a thumb is displaced to the needle body side. For this reason, the hooking portion of the crochet can be provided on the extension line in the axial direction of the base end portion from the gripping position of the thumb.

Furthermore, it has been found that knitting yarn can be easily scooped by displacing the shaft tip of the needle body to the side opposite to the side where the recess is provided with respect to the shaft of the base end. That is, in the knitting operation, the operation of scooping the knitting yarn by inserting the key portion provided at the tip into the predetermined gap of the knitted knitted body is repeated. Since the knitted body is normally positioned below the thumb, the knitting is knitted in the above operation by displacing the hook part from the side opposite to the side where the concave portion is provided, that is, from the side gripped by the thumb. It becomes easier to scoop the thread. In particular, in the present invention, since the holding position of the thumb can be brought close to the needle body by providing the concave portion, the tip of the needle body, that is, the hooking portion of the hook portion is set on the extension line of the thumb. And it became possible to displace and provide to the opposite side to the side which provided the said recessed part with respect to the axis | shaft of the said base end part.

  The amount of displacement of the tip of the needle body is not particularly limited. For example, when the amount of protrusion of the needle body from the grip body is 35 mm, 0.4 to 1 mm in the direction orthogonal to the axis of the base end portion. It is preferable to displace. Moreover, the method of displacing to the opposite side to the side which provided the said recessed part with respect to the axis | shaft of the said base end part is not specifically limited. For example, a linear needle body can be provided with an inclination of 0.4 ° to 0.6 ° on the side opposite to the side where the concave portion is provided with respect to the axis of the base end portion. The displacement amount can be changed according to the thickness of the grip body and the protrusion amount of the needle body.

  When the inclination angle of the needle body is smaller than 0.4 °, the amount of displacement of the tip of the needle body becomes small, and the above effect cannot be expected. On the other hand, when it becomes larger than 0.6 °, the grip body cannot be provided. In addition, it is preferable to set so that the said latching part may be located on the extended line of the said axial direction from the grip position of a thumb within said angle range. Further, only the portion of the needle body extending from the grip body can be bent and inclined at a predetermined angle.

  By tilting the needle body toward the side opposite to the side where the concave portion is provided, the position of the key part of the needle body is displaced from the gripping position to the opposite side as compared with the conventional key needle. With this configuration, the hook portion can be easily inserted into the stitches of the knitted body, and the knitting yarn can be easily scooped. Therefore, the crochet can be gripped and knitted with an unprecedented feel, and a crochet that does not get tired even when used for a long time can be configured.

  Further, the thickness of the grip body is reduced at the portion where the concave portion is provided. For this reason, there is a problem in that a recess having a depth that can position the thumb reliably cannot be provided, the thickness of the grip body at the bottom of the recess is reduced, the strength of the grip body is reduced, and the grip feeling is reduced. . In this invention, the thickness of a grip body can be increased in the site | part which provides a recessed part by providing the said needle body inclining. For this reason, there also exists an effect that the recessed part of required depth can be provided.

  Furthermore, in order to ensure the depth of the recess, it is preferable to form a flat portion of the needle body corresponding to the recess. By adopting this configuration, it is possible to provide a deeper recess. Moreover, it becomes easy to set the said hook part on the said axial direction extension line of the bottom face of a recessed part.

  The recess is preferably formed at a depth of 1 to 2 mm from the surface of the base end. Thereby, while being able to position a thumb in a predetermined position, the slip of the axial direction between grip parts can be prevented. In addition, the crochet can be stably held with a small gripping force. If the depth of the recess is 1 mm or less, the thumb cannot be securely hooked. On the other hand, it is difficult to provide a recess having a depth of 2 mm or more, and the thickness of the grip body at other parts increases, resulting in a decrease in usability.

  Furthermore, it is preferable to provide a first bulging portion that bulges outward in the radial direction from the surface of the base end portion on the opposite side of the shaft from the side where the concave portion is provided. Moreover, it is preferable to provide the 2nd bulging part which bulges radially outward from the surface of the said base end part in the both-sides edge part of the direction orthogonal to the said axis | shaft in the bottom face of the said recessed part. Each of the bulging portions preferably bulges at a maximum height at a portion corresponding to the bottom surface of the concave portion, and forms a cross section along the axis in an arc shape.

  By providing each bulging part, a gripping surface for positioning the index finger and the middle finger can be formed between the bulging parts. Thereby, the pressing force acting by the thumb can be reliably backed up by the index finger and the middle finger. In addition, the required gripping force can be reduced and the operability is improved.

  Although the form of each said bulging part is not specifically limited, It is preferable to form the said bulging part with the maximum height of 2-3 mm from the surface of the said base end part. Thereby, it is possible to provide a gripping surface capable of applying a sufficient gripping force.

  The base end portion is formed in a rod shape having a circular cross section, and the radially outer surface of the latching portion is radially outward from an extension line passing through the bottom surface position of the concave portion parallel to the axis of the base end portion. It is preferable to be configured to be located radially inward from the extension line of the base end surface on the side where the concave portion is provided. With the above-described configuration, the hooking portion for hooking the knitting yarn is set on the substantially extended line in the axial direction from the gripping position (surface position) of the thumb. For this reason, it becomes easy to scoop the knitting yarn, and a sense of unity between the crochet and the fingers can be obtained.

  Usually, the grip part is gripped between the thumb, index finger and middle finger. In order to hold the gripping portion more stably, a cross section perpendicular to the axis of the base end portion of the portion where the recess is provided is divided into a bottom surface of the recess, the first bulging portion, and the second It is preferable to make it into a triangular shape composed of a pair of gripping surfaces formed between the bulging portions. By adopting this configuration, each finger can be positioned and gripped stably. In particular, since the angular position of the finger around the axis can be set reliably, the operability of the crochet is improved. In addition, the gripping force necessary for the operation can be reduced. In addition, even a beginner can easily find the position where the crochet is held, which makes it suitable as a crochet for beginners.

  Further, in order to enhance the fit between each fingertip and the gripping portion, it is preferable to form the bottom surface of the recess and the pair of gripping surfaces in a curved shape recessed inward. The amount of depression of the curved surface is not particularly limited. For example, an effect can be expected by forming a depression of 0.02 mm to 0.12 mm.

  The length of the portion of the needle body that extends from the grip body is not particularly limited, but it is preferably extended from the tip of the grip to a length of 30 to 40 mm. If the amount of extension is smaller than 30 mm, the latching portion is too close to the thumb and the range of movement of the latching portion becomes small, and the operability is lowered. On the other hand, when it becomes larger than 40 mm, the moving range of the latching portion becomes too large, and it becomes difficult to scoop the knitting yarn. The securing portion is preferably set at the position described above after securing the extension length.

  It is possible to provide a crochet that can prevent a finger from slipping and can perform a knitting operation by positioning the finger at a predetermined position and can operate with a sense of unity with the finger.

In the present embodiment, the concave portion 7 has an axial length set to L2 = about 30 mm and a central portion set to an axial position where L3 = about 18 mm from the tip of the grip body. Further, the depth H1 at the central portion of the concave portion 7 is set to H1 = about 1.5 mm from the surface 5a of the base end portion 5.

  The recess 7 is gripped by the thumb. By providing the concave portion 7, it is possible to prevent the thumb from sliding in the axial direction, and it is possible to position the axial position of the thumb. As described above, in the present embodiment, since the center of the concave portion 7 in the axial direction is set to a position of L3 = about 18 mm from the tip of the grip body 3, the thumb is also positioned so as to grip this position. The The protruding length of the needle body 2 from the tip of the grip body is L1 = about 35 mm, and thereby the distance between the thumb and the tip of the needle body 2 is set.

  As shown in FIG. 2, the needle body 2 has a flat portion corresponding to the concave portion 7 in order to ensure the depth of the concave portion 7. Thereby, it becomes easy to ensure the depth of the recess 7.

  As shown in FIGS. 9 and 11, in the gripping portion 6, it swells radially outward from the surface of the base end portion on the opposite side across the shaft 9 and the side where the recess 7 is provided. A protruding first bulging portion 10 is formed. The first bulging portion 10 bulges radially outward from the surface of the base end portion 5, and an edge of a cross section along the shaft 9 is formed in an arc shape. Further, as shown in FIGS. 5 and 11, the second bulge radially outward from the surface of the base end 5 at both side edges in the direction orthogonal to the shaft 9 on the bottom surface 7 a of the recess 7.
