CROCHET ANTI-SLIP STRUCTURE

Abstract

A crochet anti-slip structure includes a crochet shaft and an anti-slip sleeve. The crochet shaft is rod-shaped and has a crochet section and a binding section, and at least one arc-shaped convex body having an expanded diameter is disposed at the outer periphery of the binding section. The anti-slip sleeve is made of elastic plastic and has a binding hole configured to be opposite to the binding section for inserting the binding section into the binding hole to achieve an anti-slip effect between the crochet shaft and the anti-slip sleeve as well as an anti-slip effect for a user to grip and use a crochet.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] With reference to FIG. 1 for a crochet anti-slip structure of the present invention, the crochet anti-slip structure includes: a crochet shaft 10 and an anti-slip sleeve 20, which are integrally formed to constitute a combined crochet of the present invention. Since the crochet shaft 10 and the anti-slip sleeve 20 are manufactured separately and then combined into a whole piece, therefore different materials can be selected for manufacturing the crochet shaft 10 and the anti-slip sleeve 20 respectively. Wherein, the anti-slip sleeve 20 should provide sufficient softness to a user’s hand for the anti-slip effect to prevent pains or injuries caused to the user’s hand by a long time use of the crochet, so that the anti-slip sleeve 20 is preferably made of an elastic material including but not limited to rubber or Silicone.

[0028] With reference to FIGS. 2-4, the crochet shaft 10 has a crochet section 11 and a binding section 12, which are integrally formed as a whole, and the crochet section 11 has a hook portion 13 disposed on another side opposite to the binding section 12 and at least one arc-shaped convex body 14 having an expanded diameter and disposed at an outer periphery of the binding section 12. In an embodiment, the hook portion 13 is substantially a smooth surface for facilitating the hooking of a thread, so that the crochet shaft 10 is preferably made of a non-elastic material including but not limited to aluminum and plastic.

[0029] The anti-slip sleeve 20 has a binding hole 21 formed thereon and configured to be corresponsive to the binding section 12 of the crochet shaft 10, and the binding hole 21 does not penetrate through the anti-slip sleeve 20 and has an inlet 22 to allow the binding section 12 of the crochet shaft 10 to be inserted from the inlet 22 into the binding hole 21, and a tight-fit state is defined between the arc-shaped convex body 14 of the crochet shaft 10 and a contact surface of the binding hole 21 of the anti-slip sleeve 20 to increase its frictional resistance with the contact surface of the anti-slip sleeve 20, and produce a joint anti-slip mechanism with the arc-shaped convex body 14 and the binding hole 21 in order to effectively prevent the crochet shaft 10 and the anti-slip sleeve 20 from being loosened or slipped from each other, and thus the invention has the advantages of strong structural strength and uneasiness of being loosened or slipped.

[0030] Due to the advantages of the strong structural strength and uneasiness of being loosened or slipped the present invention, the crochet provides better comfort, faster and longer crocheting, and reducing the risk of hand fatigue, numbness or pain from repetitive movements inherent in crochet activity.

[0031] A neck portion 15 having a reduced diameter relative to the arc-shaped convex body 14 is disposed adjacent to the junction of the binding section 12 and the crochet section 11 of the crochet shaft 10, such that the crochet section 11 has an external diameter greater than the external diameter of the neck portion 15 of the binding section 12, and a vertical braking surface 16 is formed between the crochet section 11 and the adjacent connected surface of the binding section 12 for limiting the depth of the binding section 12 to be inserted into the binding hole 21 of the anti-slip sleeve 20, such that the binding hole 21 cooperating with the vertical braking surface 16 jointly wrap the binding section 12. The arc-shaped convex body 14 is adjacent to a position of the neck portion 15 opposite to the vertical braking surface 16.

[0032] With reference to FIGS. 2 and 5, an exhaust hole 23 if formed at a position of the binding hole 21 of the anti-slip sleeve 20 opposite to the inlet 22 of the binding hole 21 and communicated with the outside. The exhaust hole 23 is provided for discharging the air accumulated in the binding hole 21 during the process of assembling the crochet shaft 10 with the anti-slip sleeve 20 to make the assembling process more smoothly and save time and effort.

[0033] In FIGS. 2~4, an outer surface of the anti-slip sleeve 20 has a flat thumb rest 24. The thumb rest 24 is configured to be corresponsive to the arc-shaped convex body 14 of the crochet shaft 10. The arc-shaped convex body 14 also has a flat plane 17 configured to be corresponsive to the thumb rest 24 and provided for wrapping the thumb rest 24 by the exterior of the plane 17 after the binding section 12 of the crochet shaft 10 is inserted into the binding hole 21 of the anti-slip sleeve 20, so as to prevent the crochet shaft 10 and the anti-slip sleeve 20 from being deflected relative to each other.

[0034] The flat thumb rest 24 of the anti-slip sleeve 20 is provided for the user to identify the direction of the hook portion 13 by tactile sensation when the user grasp the thumb rest 24 by hand, so as to rotate the crochet quickly and easily during the crocheting process, and place the hand a holding the anti-slip sleeve 20 at a convenient distance from the hook portion 13, in order to complete the crochet pattern efficiently and quickly.

[0035] In FIGS. 6~8, the anti-slip structure can be applied to various crochets of different size/diameter, such as a general crochet having a crochet section 11 with a diameter of 3 mm-15 mm, and such structure can prevent the crochet shaft 10 and the anti-slip sleeve 20 from being deflected relative to each other and achieve a double anti-slip effect by the anti-slip sleeve 20 when the user is holding and using the crochet.

[0036] Compared with the prior art, the crochet of the present invention as shown in FIGS. 1~5 has the following advantages:

[0037] (1) This invention provides a crochet having a crochet shaft 10 and an anti-slip sleeve 20 which are manufactured separately and then combined to produce the crochet, and at least one arc-shaped convex body 14 having an expanded diameter and formed on the crochet shaft 10 to improve its frictional resistance with the contact surface of the anti-slip sleeve 20, such that the two are in a tight-fit state and the invention has the advantages of strong structure strength and uneasiness to be loosened or slipped.

[0038] (2) The anti-slip sleeve 20 can be selectively made of an elastic material including but not limited to rubber or Silicone, such that the anti-slip sleeve 20 can provide an anti-slip effect and sufficient softness to the user’s hand to prevent pains and injuries of the user’s hand caused by a long time use of the crochet. In addition, the crochet shaft 10 can be selectively made of a non-elastic material including but not limited to aluminum and plastic, such that the crochet shaft 10 is smooth enough to facilitate crocheting a thread.

[0039] (3) This invention allows the user to hold the crochet comfortably, crochet faster and longer, and reduce the risk of hand fatigue, numbness or pain from repetitive movements inherent in crochet activity.

[0040] While the invention has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the invention as set forth in the claims.
