DETAILED DESCRIPTION

[0032] In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings which form a part hereof, and in which is shown by way of illustration specific embodiments in which the invention may be practiced. In this regard, directional terminology, such as front, rear, upper, lower, etc., is used with reference to the orientation of the Figure(s) being described. The members of the present invention can be positioned in a number of different orientations. As such, the directional terminology is used for purposes of illustration and is in no way limiting. Accordingly, the drawings and descriptions will be regarded as illustrative in nature and not as restrictive. Also, if not specified, the term connect is intended to mean either an indirect or direct mechanical connection. Thus, if a first device is connected to a second device, that connection may be through a direct mechanical connection, or through an indirect mechanical connection via other devices and connections.

[0033] Furthermore, the ordinal number terminology, such as first, second and third, can be used to describe various elements, and the elements are not limited by definition of the ordinal number terminology. For example, the mere usage of the ordinal numbers first and second before the term device (1) does not indicate that either device comes before or after any other in order or location; (2) does not indicate that either device occurs or acts before or after any other in time; and (3) does not indicate that either device ranks above or below any other, as in importance or quality. The mere usage of ordinal numbers does not define a numerical limit to the features identified with the ordinal numbers. For example, the mere usage of the ordinal numbers first and second before the term device does not indicate that there are exactly two devices. The term plurality means two or more, unless expressly specified otherwise.

[0034] As shown in FIG. 1A, FIG. 1B and FIG. 2, in a first embodiment, a strap member 1000 includes a strap body 1 and a plurality of hook portions 100. The strap body 1 includes a first surface 1a, e.g., a front surface, and a second surface 1b, e.g., a rear surface, opposite to the first surface 1a. Each hook portion 100 includes a hole structure 10 and at least one hook structure 2. Each hole structure 10 penetrates through the strap body 1 and includes a first opening 10a formed on the first surface 1a and a second opening 10b formed on the second surface 1b. Each hook structure 2 is at least partially disposed inside the corresponding hole structure 10 and connected to a hole wall of the corresponding hole structure 10.

[0035] As shown in FIG. 3A to FIG. 3F, each hook portion 100 further includes at least one beam 21 disposed on the second surface 1b of the strap body 1 and extending along the second surface 1b of the strap body 1. In other words, a longitudinal direction of each beam 21 is substantially parallel to the second surface 1b of the strap body 1, and a distal beam surface of each beam 21 is connected to the second surface 1b of the strap body 1.

[0036] At least one end of each beam 21 stretches into the corresponding hole structure 10, and each hook structure 2 is formed on the corresponding end of the corresponding beam 21 stretching into the corresponding hole structure 10.

[0037] Specifically, as shown in FIG. 3F, each beam 21 can have only one end stretching into the corresponding hole structure 10, and the two corresponding beams 21 of the two adjacent hook portions 100 can be integrally connected to each other, so as to form an integral structure.

[0038] In order for easy manufacture/production, as shown in FIG. 1B, each hook structure 2 is a conical column and includes a first end, e.g., an upper end, and a second end, e.g. a lower end. A diameter of each hook structure 2 gradually decreases from the second end of each hook structure 2 toward the first end of each hook structure 2. A longitudinal direction of each hook structure 2 is substantially perpendicular to the strap body 1. The second end of each hook structure 2 is connected to the hole wall of the corresponding hole structure 10, e.g., by the corresponding beam 21, and located adjacent to the second surface 1b of the strap body 1 and away from the first surface 1a of the strap body 1, and the first end of each hook structure 2 is located adjacent to the first surface 1a of the strap body 1 and away from the second surface 1b of the strap body 1.

[0039] As shown in FIG. 1A and FIG. 3D, a length or a height of each hook structure 2 is less than a thickness of the strap body 1, such that each hook structure 2 does not protrude out of the corresponding hole structure 10 beyond the first surface 1a of the strap body 1. Therefore, it prevents increase of an overall thickness of the strap member 1000.

[0040] Specifically, as shown in FIG. 1A and FIG. 3A, the hole structures 10 are in a column staggered arrangement, i.e., the hole structures 10 aligned in two adjacent columns are offset from each other.

[0041] More specifically, each hole structure 10 can be a circular hole structure for easy manufacture/production. Each hook portion 100 can include six hook structures 2. As shown in FIG. 3E, the six hook structures 2 can be arranged symmetrically relative to a center of the corresponding hole structure 10. Besides, as shown in FIG. 3F, each hook portion 100 can include six beams 21 radially arranged relative to the center of the corresponding hole structure 10. Each of six hook structures 2 can be formed on an end of the corresponding beam 21 stretching into the corresponding hole structure 10, and an included angle between the two adjacent beams 21 of each hook portion 100 can be 60 degrees.

[0042] Preferably, the strap body 1 can be a soft or flexible strap-shaped structure.

[0043] Preferably, the strap member 1000 can be made of a plastic material and through an insert-molding process.

[0044] The strap member 1000 of this embodiment can be configured to cooperate with a cooperating strap member 3000. The strap member 1000 and the cooperating strap member 3000 can form a strap assembly suitable for being attached on a cloth, a bag, a shoe or the like by sewing.

[0045] Specifically, as shown in FIG. 3G and FIG. 3H, the cooperating strap member 3000 can be used as a female strap member, and the strap member 1000 can be used as a male strap member. The cooperating strap member 3000 includes a cooperating surface 3a and a plurality of loop structures 3b disposed on the cooperating surface 3a and configured to detachably engage with the hook structures 2 of the plurality of hook portions 100 through the second openings 10b to bind the second surface 1b of the strap body 1 and the cooperating surface 3a of the cooperating strap member 3000 together.

[0046] Besides, as shown in FIG. 4A to FIG. 6D, different from the first embodiment, in a second embodiment, each hook portion 100 further includes an island structure 3 and at least one connecting rib 220.

[0047] As shown in FIG. 4B, FIG. 6C and FIG. 6D, each island structure 3 is disposed on a middle part of the corresponding hole structure 10, and each connecting rib 220 is connected to the corresponding island structure 3 and the hole wall of the corresponding hole structure 10, i.e., each island structure 3 is connected to the hole wall of the corresponding hole structure 10 by the corresponding connecting rib 220.

[0048] Preferably, in the second embodiment, as shown in FIG. 4B and FIG. 6C, each hook portion 100 can further include at least one auxiliary hook structure 2 formed on the at least one connecting rib 200 for enhancing a bonding strength of the first surface 1a of the strap body 1 and the cooperating surface of the cooperating strap member.

[0049] Besides, in the second embodiment, as shown in FIG. 6B and FIG. 6D, each hook portion 100 further includes at least one auxiliary beam 22 disposed on the second surface 1b of the strap body 1 and extending along the second surface 1b of the strap body 1. In other words, a longitudinal direction of each auxiliary beam 22 is substantially parallel to the second surface 1b of the strap body 1, and a distal beam surface of each auxiliary beam 22 is connected to the second surface 1b of the strap body 1.

[0050] Specifically, as shown in FIG. 6C and FIG. 6D, at least one end of each auxiliary beam 22 stretches into the corresponding hole structure 10, and each connecting rib 220 is formed on the corresponding end of the corresponding auxiliary beam 22.

[0051] As shown in FIG. 6D, each auxiliary beam 22 can have only one end stretching into the corresponding hole structure 10, and the corresponding auxiliary beams 22 of adjacent two of the plurality of hook portions 100 can be integrally connected to each other.

[0052] Furthermore, as shown in FIG. 6D, in the second embodiment, each beam 21 can have only one end stretching into the corresponding hole structure 10, and the corresponding beams 21 of adjacent two of the plurality of hook portions 100 can be separated from each other.

[0053] More specifically, as shown in FIG. 6C and FIG. 6D, in the second embodiment, each hole structure 10 can be a circular hole structure. The island structure 3 can be a substantially triangular structure. Each hook portion 100 can include three auxiliary beams 22 and three connecting ribs 220 formed on the three auxiliary beams 22 respectively and connected to three peak portions of the island structure 3 respectively and the hole wall of the corresponding hole structure 10. Each hook portion 100 can include six auxiliary hook structures 2 arranged symmetrically relative to the center of the corresponding hole structure 10, and every two of the six auxiliary hook structures 2 are symmetrically formed on two sides of each connecting rib 220. Moreover, each hook portion 100 can include three hook structures 2 arranged symmetrically relative to the center of the corresponding hole structure 10, and three beams 21 radially arranged relative to the center of the corresponding hole structure 10. Each of three hook structures 2 can be formed on an end of the corresponding beam 21 stretching into the corresponding hole structure 10, and an included angle between the two adjacent beams 21 of each hook portion 100 can be 120 degrees.

[0054] Other details of this embodiment are identical to the one of the first embodiment. Detailed description is omitted herein for simplicity.

[0055] The strap member of the second embodiment also can be configured to cooperate with the cooperating strap member, so as to cooperatively form another strap assembly suitable for being attached on a cloth, a bag, a shoe or the like by sewing.

[0056] Understandably, the present invention is not limited to the aforementioned embodiments, and there can be various embodiments. For example, in another embodiment, the auxiliary hook can be formed on the island structure. In another embodiment, the beam can be omitted, i.e., there can be only auxiliary beams on the second surface of the strap body. In another embodiment, the hole structure can be a rectangular hole structure, a triangular hole structure, a hexagonal hole structure, an elliptical hole structure, or any other irregular-shaped hole structure. In another embodiment, the hook structures or the auxiliary hook structures can be in an axially symmetrical arrangement or in an asymmetrical arrangement. In another embodiment, there can be only one hook structure and/or one auxiliary hook structure.

[0057] In contrast to the prior art, in the present invention, the hook structure does not protrude out of the hole structure penetrating through the strap body beyond the first surface of the strap body, and therefore, the strap member has a thin thickness and is suitable for being attached on a cloth, a bag or a shoe by sewing.

[0058] Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
