Abstract
Description
Technical Field
[0001] This utility model relates to the field of hook and loop fastener technology, specifically to a magnetic hook and loop fastener. Background Technology
[0002] The principle of traditional hook and loop fasteners is as follows: when the hook side contacts the loop side and pressure is applied, the hook will catch the fiber loop, forming a temporary bond; applying tension causes the hook to separate from the fiber loop, thus separating the hook side from the loop side. Traditional hook and loop fasteners can be repeatedly applied and removed, and are characterized by their simple structure, ease of use, and wide application. However, traditional hook and loop fasteners still have the following technical problems: Limited durability: After repeated use, the hooks on the hook side are prone to wear and deformation, and the fiber rings on the loop side are prone to breakage or pilling, resulting in a decrease in the stickiness of the Velcro.
[0003] Easy to attract debris: The textured surface easily attracts dust, hair and other small debris, which reduces the stickiness of the Velcro and makes cleaning more difficult.
[0004] Easily abrades clothes or skin: Due to limitations in usage scenarios, the hooks on the hook side are relatively stiff, which makes the clothes that come into contact with the hook side easily abraded or damaged. The stiff material itself also affects the user's experience and feel, especially on thin fabrics.
[0005] Loud noise during separation: Because separation relies on forced pulling to deform and separate the hook and the nap, it produces a loud tearing sound, making it unsuitable for certain environments that require quiet. Utility Model Content

Detailed Implementation
[0020] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.
[0021] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.
[0022] like Figures 1 to 9The magnetic hook and loop fastener shown includes a first hook and loop fastener 1 and a second hook and loop fastener 2. The first hook and loop fastener 1 is a first flexible magnetic attractant, and the second hook and loop fastener 2 is a second flexible magnetic attractant capable of magnetically attracting and separating from the first hook and loop fastener 1. The first hook and loop fastener 1 includes a first hook and loop fastener body 11 with a first side surface and a plurality of first protrusions 12 protruding from the first side surface, with a plurality of first tooth grooves 13 formed between the plurality of first protrusions 12. The second hook and loop fastener 2 includes a second hook and loop fastener body 21 with a second side surface and a plurality of second protrusions 22 protruding from the second side surface, with a plurality of second tooth grooves 23 formed between the plurality of second protrusions 22. When the first hook and loop fastener 1 and the second hook and loop fastener 2 are magnetically attracted together, the first side surface and the second side surface are opposite each other, and the plurality of first protrusions 12 engage with the plurality of second tooth grooves 23, and the plurality of second protrusions 22 engage with the plurality of first tooth grooves 13.
[0023] By adopting the above technical solution, the first hook and loop fastener 1 and the second hook and loop fastener 2 are configured as flexible magnetic components. Magnetic attraction provides the bonding force between the first hook and loop fastener 1 and the second hook and loop fastener 2. This achieves the hook and loop fastener bonding function without the need for hook and loop sides, thus avoiding the problems of limited durability, easy adhesion of debris, easy abrasion of clothing or skin, and loud noise during separation inherent in traditional hook and loop fasteners. It features greater durability, easier maintenance, skin-friendliness, and quieter operation.
[0024] If the first hook and loop fastener 1 and the second hook and loop fastener 2 are only connected by magnetic attraction, in some application scenarios, such as knee braces or other stress-prone applications, there may be a problem of misalignment or accidental separation. Therefore, multiple first protrusions 12 and multiple first grooves 13 are constructed on the first hook and loop fastener 1, and multiple second protrusions 22 and multiple second grooves 23 are constructed on the second hook and loop fastener 2. The multiple first protrusions 12, multiple first grooves 13, multiple second protrusions 22, and multiple second grooves 23 constitute an interlocking structure. When the first hook and loop fastener 1 and the second hook and loop fastener 2 are magnetically connected, the interlocking force of the interlocking structure effectively reduces the relative movement of the first hook and loop fastener 1 and the second hook and loop fastener 2, reducing the possibility of misalignment or accidental separation of the first hook and loop fastener 1 and the second hook and loop fastener 2.
[0025] In other words, by forming the above-mentioned interlocking structure, the magnetic hook and loop fastener proposed in this application can meet the usage needs of most application scenarios, forming a product that can replace traditional hook and loop fasteners and can be accepted by the market.
[0026] Obviously, in practical implementation, the structure and shape of the multiple first protruding teeth 12, multiple first tooth grooves 13, multiple second protruding teeth 22, and multiple second tooth grooves 23 can be designed according to the actual situation, as long as they can form a meshing structure. For example, the first protruding teeth 12 and the second protruding teeth 22 can adopt a pin-shaped structure.
[0027] As a preferred example, the first tooth 12 includes a first tooth body 121 with a square cross-section perpendicular to its protrusion direction, and the second tooth 22 includes a second tooth body 221 with a square cross-section perpendicular to its protrusion direction. By using the square cross-sections of the first tooth body 121 and the second tooth body 221, square first tooth grooves 13 and 23 can be formed. The square cross-sections of the first tooth body 121 and the square second tooth grooves 23 can form a stable and tight fit structure, and the square cross-sections of the second tooth body 221 and the square first tooth grooves 13 can also form a stable and tight fit structure, enabling the first hook and loop fastener 1 and the second hook and loop fastener 2 to achieve a stable and tight connection.
[0028] In some embodiments, a first guide surface is provided on the outer periphery of the end of the first protruding tooth 12, and a second guide surface is provided on the outer periphery of the end of the second protruding tooth 22. The first guide surface can guide the first protruding tooth 12 to be more smoothly engaged in the second tooth groove 23, and the second guide surface can guide the second protruding tooth 22 to be more smoothly engaged in the first tooth groove 13.
[0029] In practice, the first guide surface is usually inclined gradually toward the side of the first tooth 12 opposite to the first guide surface along the protrusion direction of the first tooth 12; the second guide surface is usually inclined gradually toward the side of the second tooth 22 opposite to the second guide surface along the protrusion direction of the second tooth 22.
[0030] To better achieve the guiding function, the end of the first tooth 12 is usually constructed as a conical structure, a wedge structure, or a hemispherical structure, and the end of the second tooth 22 is usually constructed as a conical structure, a wedge structure, or a hemispherical structure.
[0031] In some embodiments, the bottom of the first toothed groove 13 is provided with a first groove portion 132 for engaging with the end of the second protruding tooth 22, and the bottom of the second toothed groove 23 is provided with a second groove portion 232 for engaging with the end of the first protruding tooth 12. By adopting the above technical solution, by forming an engaging structure, the first hook and loop fastener 1 and the second hook and loop fastener 2 can be more stably and tightly coupled.
[0032] As a preferred example, the end of the first tooth 12 is a first tooth end 122 connected to the end of the first tooth body 121, and the end of the second tooth 22 is a second tooth end 222 connected to the end of the second tooth body 221. The cross-section of the first tooth body 121 perpendicular to the protruding direction of the first tooth 12 is square, and the cross-section of the second tooth body 221 perpendicular to the protruding direction of the second tooth 22 is square. The first tooth end 122 and the second tooth end 222 are both pyramidal. Correspondingly, the first tooth groove 13 includes a first groove portion 132 corresponding to the second tooth end 222 and a third groove portion 131 corresponding to the second tooth body 221, and the second tooth groove 23 includes a second groove portion 232 corresponding to the first tooth end 122 and a fourth groove portion 231 corresponding to the first tooth body 121.
[0033] In some embodiments, a plurality of first protrusions 12 are arranged in an array and a plurality of second protrusions 22 are arranged in an array, which makes it easier for the magnetic hook and loop fasteners to be joined together and also helps to improve the meshing force.
[0034] In some embodiments, at least a portion of the plurality of first protrusions 12 are arranged in a transverse array, and at least a portion of the plurality of first protrusions 12 are arranged in a longitudinal array; at least a portion of the plurality of second protrusions 22 are arranged in a transverse array, and at least a portion of the plurality of second protrusions 22 are arranged in a longitudinal array. This combination of transverse and longitudinal array distributions generates meshing forces in multiple directions, further improving the bonding stability of the first hook and loop fastener 1 and the second hook and loop fastener 2. Even when the magnetic hook and loop fastener twists, the bonding between the first hook and loop fastener 1 and the second hook and loop fastener 2 can be maintained relatively well.
[0035] In some embodiments, the first hook and loop fastener body 11 is a sheet-like structure, and the second hook and loop fastener body 21 is a sheet-like structure, which is easy to sew onto the fabric.
[0036] In some embodiments, the first hook and loop fastener 1 includes a first flexible substrate and a first magnetic powder mixed into the first flexible substrate, and the second hook and loop fastener 2 includes a second flexible substrate and a second magnetic powder mixed into the second flexible substrate. The first magnetic powder and the second magnetic powder can provide magnetic attraction, enabling the first hook and loop fastener 1 and the second hook and loop fastener 2 to magnetically attract each other.
[0037] Obviously, in practical implementation, the first magnetic powder can be mixed into the first flexible substrate, and the first iron powder can be mixed into the second flexible substrate, so that the first hook and loop fastener 1 and the second hook and loop fastener 2 can be magnetically attracted to each other. Alternatively, the first iron powder can be mixed into the first flexible substrate, and the second magnetic powder can be mixed into the second flexible substrate, so that the first hook and loop fastener 1 and the second hook and loop fastener 2 can be magnetically attracted to each other. The iron powder can also be replaced with other powders that can generate magnetic attraction with a magnet.
[0038] The amount of magnetic powder and iron powder mixed into the flexible matrix can be adjusted according to the magnetic attraction force requirements. Increasing the amount of magnetic powder and iron powder can increase the magnetic attraction force, while decreasing the amount of magnetic powder and iron powder can decrease the magnetic attraction force.
[0039] In some embodiments, both the first flexible substrate and the second flexible substrate are rubber substrates. The rubber substrate meets the flexibility requirements of magnetic hook and loop fasteners, making them easier to maintain, more skin-friendly, and quieter.
[0040] In some embodiments, both the first and second flexible substrates are integrally molded structures, which is easy to implement. In specific implementations, the first and second flexible substrates can be manufactured by compression molding.
