Description

This disclosure relates to a craft needle, and in particular to a craft needle suitable for use when embroidering on fabric.

In the field of handicrafts, there is a known embroidery technique that uses a needle called a punch needle. A punch needle has a cylindrical needle, and embroidery is performed by threading thread through this cylindrical needle. A needle used for this type of embroidery is described, for example, in Patent Document 1.

In a punch needle, for example, a thread hole is formed near the tip of the needle. The thread hole penetrates the cylindrical wall of the needle in the thickness direction. The thread used for embroidery is inserted into the needle and also passed through the thread hole. By repeatedly piercing the fabric with this needle, a loop is formed as shown in FIG. 8 of Patent Document 1. The height of the loop is a dimension according to the needle's protruding length (the length of the part of the needle that protrudes from the tip of the handle). In the needle disclosed in Patent Document 1, a set screw is provided at the tip of the handle. By tightening the set screw, the needle is pressed from the outer periphery toward the inside, and the needle is held at the tip of the handle. With such a configuration equipped with a set screw, the protruding length of the needle can be adjusted, and the height of the loop can be changed by adjusting the protruding length of the needle.

In embroidery using punch needles, if the thread used is thick, such as wool, a relatively large diameter needle is used, and the thickness of the fabric into which the needle is pierced is also relatively thick. In this case, a relatively large reaction force acts on the needle when piercing the fabric, and the holding force of the needle by the set screw is insufficient, which can cause the needle to slip out of place.

The following describes the embodiment of the needle in detail with reference to the drawings.

Figures 1 to 5 show a needle for a sewing machine according to one embodiment. The illustrated needle for sewing machine A1 includes a handle 1, a needle body 2, a connecting member 3, a fixing member 4, and a ring member 5.

The handle 1 is a long cylindrical rod that extends in a certain direction. The handle 1 is integrally formed from a synthetic resin with a certain strength, such as ABS resin (acrylonitrile-butadiene-styrene resin). However, the material of the handle 1 is not limited to the above-mentioned ABS resin, and various choices are possible. In the following explanation, the upper side in Figures 1 and 3 to 5 corresponds to the base end side of each of the components of the handle 1, needle body 2, and connecting member 3, and the lower side in the figures corresponds to the tip end side of each of the above-mentioned components.

As shown in Figures 3 to 5, a handle-side recess 111 is formed in the base end 11 (upper end in the figure) of the handle 1. The handle-side recess 111 is a portion recessed from the base end surface of the handle 1 toward the tip end, and is a portion into which the connection member side protrusion 32 of the connection member 3 described below can be fitted. In this embodiment, a groove 112 and an engagement hole 113 are formed in the handle-side recess 111. A plurality of grooves 112 are formed at intervals in the circumferential direction, and extend from the base end surface of the base end 11 toward the tip end with a predetermined width and a predetermined length. The engagement hole 113 is a hole that penetrates the base end 11 in the radial direction, and is formed adjacent to the groove 112 in the circumferential direction. In this embodiment, two engagement holes 113 are provided, and these engagement holes 113 are arranged at equal intervals in the circumferential direction of the base end 11.

A handle-side convex portion 121 is formed at the tip 12 (lower end portion in the figure) of the handle 1. The handle-side convex portion 121 has a smaller outer diameter than other portions and is a portion that can fit into a connection member-side concave portion 31 of the connection member 3 described below. An engagement protrusion 122 is provided on the outer periphery of the handle-side convex portion 121. The engagement protrusion 122 bulges outward in the radial direction from the outer periphery of the handle-side convex portion 121. In this embodiment, two engagement protrusions 122 are provided, and these engagement protrusions 122 are arranged at equal intervals in the circumferential direction of the tip 12.

The needle body 2 is approximately cylindrical and fixed to the handle 1. In this embodiment, the needle body 2 is fixed to the handle 1 via the fixing member 4. Specifically, the fixing member 4 has a cylindrical base end and a pair of locking pieces 41 facing each other at the tip end. The locking pieces 41 are formed with locking protrusions 42 that bulge inward. A pair of locking holes 21 facing each other are formed at the base end of the needle body 2. The locking protrusions 42 of the fixing member 4 are fitted into the locking holes 21. The locking protrusions 42 are fitted into the pair of locking holes 21 by, for example, aligning the locking protrusions 42 with the locking holes 21 while elastically deforming the locking pieces 41 of the fixing member 4 so as to separate them from each other, and restoring the locking pieces 41 to their original positions. In this way, the needle body 2 is supported by the fixing member 4. The fixing member 4 is inserted into the handle 1 from the base end side of the handle 1, and the fixing member 4 and the handle 1 are fixed together, for example, by adhesive.

In this embodiment, as shown in FIG. 3 etc., the tip of the needle body 2 (needle tip 23) is cut at an angle. A threading hole 24 is formed at the tip of the needle body 2. The threading hole 24 penetrates the cylindrical wall of the needle body 2 in the thickness direction. The needle body 2 configured in this way is set so that the length L1 of the portion (protruding portion 22) protruding from the tip 12 of the handle 1 is a predetermined length. The needle body 2 is made of, for example, a metal material.

As shown in Figures 1, 3, 4, etc., the connection member 3 is a member that is attached to the tip 12 of the handle 1. The connection member 3 is cylindrical, and is attached to the tip 12 in a state in which it surrounds the periphery of the needle body 2 (protrusion 22). In addition, another connection member 3 is attached to the connection member 3 attached to the tip 12 in a state in which it surrounds the periphery of the needle body 2 (protrusion 22).

The connection member 3 has a connection member side recess 31 and a connection member side protrusion 32. The connection member side recess 31 is a portion recessed from the base end surface of the connection member 3 toward the tip side, and the handle side protrusion 121 of the handle 1 can be fitted into the connection member side recess 31.

In this embodiment, as shown in Figs. 5, 6, and 7, the connection member side recess 31 is formed with a groove 311, an engagement recess 312, and an engagement protrusion 313. The grooves 311 are formed at intervals in the circumferential direction and extend from the base end surface of the connection member 3 toward the tip end side with a predetermined width and a predetermined length. The engagement recess 312 is a recessed portion on the inner peripheral surface of the connection member side recess 31 and is formed adjacent to the groove 311 in the circumferential direction. The engagement protrusion 313 is provided between the adjacent grooves 311 and engagement recesses 312 and is a portion that bulges radially inward. Two grooves 311, two engagement recesses 312, and two engagement protrusions 313 are provided, and these grooves 311, the engagement recesses 312, and the engagement protrusions 313 are each arranged at equal intervals in the circumferential direction of the connection member 3.

5 and 6, the handle-side convex portion 121 can be fitted into the connection member-side concave portion 31 when the groove 311 of the connection member-side concave portion 31 and the engagement protrusion 122 of the handle-side convex portion 121 are aligned in the circumferential direction. When the connection member 3 is rotated in the circumferential direction with the handle-side convex portion 121 fitted into the connection member-side concave portion 31, the engagement protrusion 122 is pressed against the engagement protrusion 313 and then accommodated in the engagement recess 312. Here, the engagement state of the handle-side convex portion 121 into the connection member-side concave portion 31 is maintained, and the connection member 3 is prevented from being separated from the tip portion 12 of the handle 1. With the above configuration, the connection member 3 is detachably attached to the tip portion 12 of the handle 1. The groove 311 of the connection member-side concave portion 31, the engagement recess 312, the engagement protrusion 313, and the engagement protrusion 122 of the handle-side convex portion 121 correspond to an example of the engagement means referred to in this disclosure.

As shown in Figures 3 to 5, the connection member side convex portion 32 has an outer diameter smaller than the other portions, and is a portion that can fit into the connection member side concave portion 31 of another connection member 3. An engagement protrusion 321 is provided on the outer periphery of the connection member side convex portion 32. The engagement protrusion 321 bulges outward in the radial direction from the outer periphery of the connection member side convex portion 32. In this embodiment, two engagement protrusions 321 are provided, and these engagement protrusions 321 are arranged at equal intervals in the circumferential direction of the connection member side convex portion 32 (connection member 3).

5, 7, etc., the connection member side convex portion 32 can be fitted into the connection member side concave portion 31 in a state where the groove 311 of the connection member side concave portion 31 (other connection member 3) and the engagement protrusion 321 of the connection member side convex portion 32 are aligned in the circumferential direction. Then, when the other connection member 3 is rotated in the circumferential direction with the connection member side convex portion 32 fitted into the connection member side concave portion 31, the engagement protrusion 321 is pressed against the engagement convex portion 313 and then accommodated in the engagement concave portion 312. Here, the fitting state of the connection member side convex portion 32 into the connection member side concave portion 31 (other connection member 3) is maintained, and the other connection member 3 is prevented from being separated from the connection member 3 attached to the tip portion 12 of the handle 1. With the above configuration, the other connection member 3 is detachably attached to the connection member 3 attached to the tip portion 12 of the handle 1. The groove 311, the engagement recess 312, the engagement protrusion 313 of the connection member side recess 31, and the engagement protrusion 321 of the connection member side protrusion 32 correspond to an example of the engagement means referred to in this disclosure.

In this embodiment, the connection member side protrusion 32 of the connection member 3 can be fitted into the handle side recess 111 of the handle 1 (base end 11). Specifically, as can be seen from Figs. 3 to 5, the connection member side protrusion 32 can be fitted into the handle side recess 111 when the groove 112 of the handle side recess 111 and the engagement protrusion 321 of the connection member side protrusion 32 are aligned in the circumferential direction. When the connection member 3 is rotated in the circumferential direction with the connection member side protrusion 32 fitted into the handle side recess 111, the engagement protrusion 321 is accommodated in the engagement hole 113. Here, the fitting state of the connection member side protrusion 32 into the handle side recess 111 is maintained, and the connection member 3 is prevented from being separated from the base end 11 of the handle 1. With the above configuration, the connection member 3 is detachably attached to the base end 11 of the handle 1. The connection member 3 is integrally formed from a synthetic resin having a predetermined strength, such as ABS resin.

The ring member 5 is a circular ring member that is detachably fitted around the tip of the handle 1 or the connecting member 3. The ring member 5 makes it easier for the user to grip the needle A1 when using it. In this embodiment, the outer circumferential surface 12a near the tip of the handle 1 and the outer circumferential surface 3a of the connecting member 3 have approximately the same outer diameter. The ring member 5 is made of an elastic member such as silicone rubber, and the inner diameter of the ring member 5 in its natural state is smaller than the outer diameter of the outer circumferential surface 12a of the handle 1 and the outer circumferential surface 3a of the connecting member 3. The ring member 5 is fitted around the tip of the handle 1 or the connecting member 3 while being stretched. When the ring member 5 is attached, the inner circumferential surface of the ring member 5 is pressed against the outer circumferential surface 12a near the tip of the handle 1 or the outer circumferential surface 3a of the connecting member 3.

The needle A1 of this embodiment is provided with multiple connecting members 3, and in the illustrated example, it is provided with three connecting members 3. In the illustrated example, the length L1 of the part (protruding part 22) of the needle body 2 protruding from the tip 12 of the handle 1 is, for example, about 5.5 cm. When one connecting member 3 is attached to the tip 12 of the handle 1, the length of the part of the needle body 2 exposed from the tip 12 of the handle 1 or the connecting member 3 is 1 cm shorter than the length L1 of the protruding part 22. In the embodiment shown in FIG. 1, two connecting members 3 are attached to the tip 12 of the handle 1, and one connecting member 3 is attached to the base end 11 of the handle 1. In the embodiment shown in FIG. 1, since two connecting members 3 are attached to the tip 12 of the handle 1, the length L2 of the part of the needle body 2 exposed from the connecting member 3 is about 3.5 cm.

Figures 8 to 10 show cases where the connection member 3 is attached in a different state to that shown in Figure 1. In the state shown in Figure 8, one connection member 3 is attached to the tip 12 of the handle 1, and two connection members 3 are attached to the base end 11 of the handle 1. In the state shown in Figure 8, one connection member 3 is attached to the tip 12 of the handle 1, so the length L3 of the part of the needle body 2 exposed from the connection member 3 is approximately 4.5 cm.

In the embodiment shown in FIG. 9, three connecting members 3 are attached to the tip 12 of the handle 1, and no connecting members 3 are attached to the base end 11 of the handle 1. In the embodiment shown in FIG. 9, because three connecting members 3 are attached to the tip 12 of the handle 1, the length L4 of the portion of the needle body 2 exposed from the connecting members 3 is approximately 2.5 cm.

In the embodiment shown in Figure 10, no connecting member 3 is attached to the tip 12 of the handle 1, and three connecting members 3 are attached to the base end 11 of the handle 1. In the embodiment shown in Figure 10, since no connecting member 3 is attached to the tip 12 of the handle 1, the length L5 of the part of the needle body 2 exposed from the tip 12 of the handle 1 is approximately 5.5 cm.

Next, we will explain examples of use and the effects of the above-mentioned needle A1.

The needle A1 of this embodiment is used to embroider on fabric C, as shown in FIG. 11. A thread Y, such as wool, is inserted through the handle 1 or the needle body 2 of the needle A1, and the thread Y is also passed through the threading hole 24. In embroidery using the needle A1, the needle body 2 is repeatedly pierced into the fabric C, forming a loop on the back side of the fabric C. The height of the loop is a dimension according to the protruding length of the needle body 2 (the length of the part of the needle body 2 exposed from the tip of the handle or the connecting member 3). The needle A1 shown in FIG. 11 is the same as the embodiment shown in FIG. 1. That is, the needle A1 of FIG. 11 has two connecting members 3 attached to the tip 12 of the handle 1, so that the length L2 of the part of the needle body 2 exposed from the connecting member 3 is about 3.5 cm.

In the needle A1, the needle body 2 is fixed to the handle 1 in a state where it protrudes a predetermined length L1 from the tip 12 of the handle 1. The connecting member 3 is removably attached to the tip 12 of the handle 1 so as to surround the periphery of the needle body 2 (protruding portion 22). With this configuration, the protruding length of the needle body 2 (the length of the part of the needle body 2 exposed from the tip 12 of the handle 1 or the connecting member 3) can be adjusted by changing the attachment state of the connecting member 3 to the tip 12 of the handle 1.

In addition, since the needle body 2 is fixed to the handle 1 (in this embodiment, it is fixed to the handle 1 via a fixing member 4), even if a large reaction force acts on the needle body 2, the needle body 2 is prevented from unduly shifting relative to the handle 1.

In this embodiment, the needle A1 is equipped with multiple connection members 3. In addition, another connection member 3 is detachably attached to the connection member 3 attached to the tip 12 of the handle 1 in a state surrounding the needle body 2 (protruding portion 22). With this configuration, as shown in Figures 1 and 9, it is possible to connect multiple connection members 3 to the tip 12 of the handle 1 in a spliced manner. This makes it possible to finely adjust the protruding length of the needle body 2 (the length of the part of the needle body 2 exposed from the tip 12 of the handle 1 or the connection member 3) in stages.

A handle-side convex portion 121 is formed at the tip 12 of the handle 1, and a connection member-side concave portion 31 and a connection member-side convex portion 32 are formed at the connection member 3. The handle-side convex portion 121 of the handle 1 can be fitted into the connection member-side concave portion 31. The connection member-side convex portion 32 can be fitted into the connection member-side concave portion 31. With this configuration, the connection structure between the tip 12 of the handle 1 and the connection member 3, or the connection structure between the connection members 3, is a structure that combines concave and convex shapes, so that the members can be smoothly connected or separated from each other.

In this embodiment, a handle-side recess 111 is formed at the base end 11 of the handle 1. The connection member-side protrusion 32 of the connection member 3 can be fitted into the handle-side recess 111. With this configuration, the connection members 3 that are not used for connection to the tip end 12 of the handle 1 can be properly held by the handle 1, and inconveniences such as loss can be avoided. In addition, by connecting multiple connection members 3 to either the tip end 12 or the base end 11 of the handle 1, the overall axial length of the handle 1 and multiple connection members 3 is maintained at a constant length, making it easy to use.

5, 6, etc., the engagement state between the handle-side convex portion 121 of the handle 1 and the connection member-side concave portion 31 of the connection member 3 is maintained by the cooperation of the groove 311, the engagement concave portion 312, the engagement convex portion 313 of the connection member-side concave portion 31, and the engagement protrusion 122 of the handle-side convex portion 121. With this configuration, the connection member 3 is prevented from being inadvertently separated from the tip portion 12 of the handle 1. Also, as described with reference to FIG. 5, 7, etc., the engagement state between the connection member-side convex portion 32 of the connection member 3 and the connection member-side concave portion 31 of the other connection member 3 is maintained by the cooperation of the groove 311, the engagement concave portion 312, the engagement convex portion 313 of the connection member-side concave portion 31, and the engagement protrusion 321 of the connection member-side convex portion 32. With this configuration, the connection members 3 connected to each other are prevented from being inadvertently separated from each other.

The outer circumferential surface 12a near the tip of the handle 1 and the outer circumferential surface 3a of the connecting member 3 have approximately the same outer diameter. The needle A1 of this embodiment also includes a ring member 5. This ring member 5 can be fitted onto either the outer circumferential surface 12a of the handle 1 or the outer circumferential surface 3a of the connecting member 3. This configuration allows the ring member 5 to be attached to a position according to the user's preference depending on the attachment state of the connecting member 3 to the tip 12 of the handle 1, making it easy to use.

The needle of the present disclosure is not limited to the above-described embodiment. The specific configuration of each part of the needle can be changed in various ways without departing from the scope of the claims.

In the above embodiment, a configuration has been described in which the connected state is maintained by the engagement of the engagement protrusion 122 and the engagement recess 312 when the handle side protrusion 121 of the handle 1 and the connection member side recess 31 of the connection member 3 are connected, but this is not limited to the above. For example, the handle side protrusion 121 may be pressed into the connection member side recess 31 to connect the handle 1 and the connection member 3. Also, the connection between the connection members 3 may be configured such that the connection member side protrusion 32 is pressed into the connection member side recess 31.

The needles disclosed herein can be used for a variety of purposes in addition to the embroidery described in the above embodiment.
