Description
Technical Field
The present invention relates to mechanical surface bonding fasteners, and more particularly to hook-to-hole mechanical surface bonding fasteners and hook-to-hook mechanical surface bonding fasteners.
Background
The most common mechanical surface-bonding fastener is a mechanical surface-bonding fastener known as 'velcro' (which is also called hook-and-loop (hooks-and-loops) type mechanical surface-bonding fastener), which is mainly composed of a 'hook side' having a hook fastener structure and a 'loop side' having a loop structure, wherein the loop side is made of a material which is usually a textile product and has a surface on which a raising treatment is performed to form loops, so that the hook fastener and the loops are engaged to achieve the effect of surface-bonding two separate objects when in use.
Although the hook-and-loop type mechanical surface bonding fastener described above is widely used in applications requiring separable bonding of two separate parts because of its easy repetitive felt-bonding and separation properties, the loops on the pile side are relatively loose structures because they are produced by subjecting a pile material (e.g., a textile product) to a raising treatment. Therefore, after the loop on the pile side engages with the hook on the hook side, the loop often moves up and down and left and right, resulting in a poor fit and a poor peel strength.
In view of the above problems with the conventional hook and loop mechanical surface bonding fasteners, there is a continuing need in the field of mechanical surface bonding fasteners to provide a mechanical surface bonding fastener with a stronger bonding effect and a higher degree of engagement.

Detailed Description
The present invention will now be described with reference to the preferred embodiments shown in the drawings.
Fig. 1 is a perspective view of a hook-to-hole mechanical surface bonding buckle 1 according to a first aspect of the present invention, fig. 2a and 2b are partially enlarged schematic top views of a hole member 3 and a hook member 5 of the hook-to-hole mechanical surface bonding buckle 1 of fig. 1, and fig. 3a, 3b and 3c are enlarged schematic side and cross-sectional views of the hole member 3 and the hook member 5, respectively, showing a process of engaging the hole member 3 and the hook member 5.
As shown, the hole member 3 includes a plurality of circular engaging holes 31 formed therein, each engaging hole 31 having an opening portion 32, a constricted portion 33 and a cavity 34. The hole portion 32 is a funnel-shaped slope inclined from the hole toward the constricted portion 33, and the depth from the hole to the constricted portion 33 is H. Further, the diameter at the hole mouth of the engaging hole 31 is D and the diameter of the constricted portion 33 is D, and the relationship between the two is D > D. In the embodiment shown in FIGS. 1-3, the holes 31 are arranged in a matrix (e.g., each hole 31 and other holes 31 in the same row and column are aligned with each other in a matrix). The opening of each engaging hole 31 is adjacent to the opening of each adjacent engaging hole 31, and the distance between the center points of two adjacent engaging holes 31 is 2D.
As shown, the hook member 5 includes a base 51 and a plurality of hooks 52 formed on a surface of the base 51. The arrangement pattern of the hooks 52 corresponds to the arrangement pattern of the engaging holes 31. Each hook 52 has a hook grip 53 connected to the base 51 and a hook head 54 formed at the end of the hook grip 53. The hook head 54 has a width W which is greater than the width W1 of the connection between the handle 53 and the head 54, and the height of the handle 53 from the surface of the substrate to the connection with the head 54 is H1. In the preferred embodiment, the hook members 5 are formed by injection molding of hot melt resin such that each hook 52 has a degree of flexibility and the hook heads 54 are compressible.
In order to provide the hook-to-hole mechanical surface-adhesive fastener 1 of the present invention with the best fastening effect, the engaging holes 31 and the hooks 52 must satisfy the following requirements in configuration and structure:
1) the number (N) of the clamping holes 31 is larger than or equal to the number (N1) of the hooks 52, namely N is larger than or equal to N1;
2) the distance (L1) between two adjacent hooks 52 is an integer multiple of the distance (L) between the centers of two adjacent engaging holes 31, i.e., L1 is nL, where n is a positive integer other than 0;
3) the width (W) of the hook head 54 is less than or equal to the diameter (D) of the hole of the clamping hole 31, but is greater than the diameter (D) of the neck part 33, namely D is more than W and less than or equal to D; and
4) the height (H1) of the hook lever 53 is substantially equal to the depth (H) of the engaging hole 31 from the hole opening to the constricted portion 33, and
in use, the hook member 5 and the hole member 3 are pressed close to each other (as shown in fig. 3A), and it is not necessary to align all the hooks 52 on the hook member 5 and all the engaging holes 31 on the hole member 3 correctly, because even if the hooks 52 and the engaging holes 31 are not aligned completely, the hooks 52 can still be automatically guided into the engaging holes 31 (as shown in fig. 3B) by their flexibility and the guiding function of the funnel-shaped hole portion 32 of the engaging holes 31. At this time, the snap head 54 having compressibility larger than the constricted portion 33 of the engaging hole 31 is pressed into the cavity 34 via the constricted portion 33 to be engaged by applying a suitable pressure, as shown in fig. 3C.
Since the height (H1) of the hook handle 53 of the hook member 5 of the present invention is substantially equal to the depth (H) of the engaging hole 31 from the hole to the constricted portion 33, the hook member 5 and the hole member 3 can have an excellent fit after engaging with each other. In addition, the hook-to-hole mechanical surface bonding buckle 1 of the present invention further prevents the hook member 5 and the hole member 3 from shifting vertically and horizontally by engaging and fixing the plurality of hooks 52 with the engaging holes 32, and also provides a higher lateral tension than the conventional hook-and-loop bonding design.
Next, a hook-to-hook mechanical surface adhesive fastener 2 according to a second aspect of the present invention will be described with reference to fig. 4 to 6, wherein fig. 4 is a schematic perspective view of the hook-to-hook mechanical surface adhesive fastener 2 according to the second aspect of the present invention; fig. 5a is a schematic top view of the hook 42 of the first hook member 4 of the hook-to-hook mechanical surface adhesive buckle 2 according to the present invention; FIG. 5b is an enlarged partial schematic view of the hook member 42 of FIG. 5 a; FIG. 6a is a schematic top view of the clasps 42 and 62 of the first hook member 4 and the second hook member 6 in engagement, wherein the base of the second hook member 6 is not shown in this figure for clarity; and FIG. 6b is a schematic side view of the hook engagement of the first and second hook members 4, 6.
As shown, the hook-to-hook mechanical surface adhesive fastener 2 of the present invention includes a first hook member 4 and a second hook member 6. The hook members 4 and 6 have a base 41 and 61, respectively, and a plurality of cylindrical hooks 42 and 62 formed on one surface of the base. Clasp members 42 and 62 have substantially the same size and diameter D1. In addition, the hooks 42 and 62 have a height and a hooking protrusion 43, 63 is formed at about half the height (e.g., about 3/5 from the base 41, 61), the diameter of the hooking protrusion 43, 63 is D2, and D2 is greater than D1. Preferably, the first and second hook members 4 and 6 are made of a flexible plastic material, such as polypropylene (p.p), so that the hook members 42 and 62 have a certain flexibility and the hooking flanges 43 and 63 have a certain elastic deformability. Since the configuration of the clasps 42 and 62 of the first and second hook members 4 and 6 is the same, the configuration and features of the clasps will be described below by taking the first hook member 4 as an example.
In detail, as shown in fig. 5a and 5b, the plurality of hook members 42 may be arranged in a matrix and adjacent four hook members 42 define a hooking space S therebetween, the hooking space S has the following dimensional characteristics: the distance D3 between the hooking flanges 43 of any two diagonally opposite hooks 42 of the four hooks 42 defining the hooking space S is greater than the diameter D1 of a single hook (e.g., the corresponding hook 62 on the second hook member 6), but less than the diameter D2 of the hooking flange of the hook (e.g., the hooking flange 63 of the hook 62), i.e., D1< D3< D2.
In use, the first hook member 4 and the second hook member 6 are pressed close to each other, and it is not necessary to correctly align all the hooks 42 on the first hook member 4 with the hooking spaces S on the second hook member 6 (or correctly align all the hooks 62 on the second hook member 6 with the hooking spaces S on the first hook member 4), because even if the hooks 42 (or the hooks 62) are not completely aligned with the corresponding hooking spaces S on the hook member 6 (or the hook member 4), the hooks 42 (or the hooks 62) can slide into the hooking spaces S through their own flexibility, and at this time, the hooking flanges 43 (or the hooking flanges 63) can pass through the four hooking flanges 63 (or the hooking flanges 43) defining the hooking spaces S by applying appropriate pressure, so as to form a hooked state as shown in fig. 6 b.
Since the hooking flange 43 (or hooking flange 63) of each hook 42 (or hook 62) of the hook-to-hook mechanical surface adhesive fastener 2 of the present invention is simultaneously engaged with the four corresponding hooking flanges 63 (or hooking flanges 43) around the hooking space S and the hooking flanges are disposed at about half the height of the hooks, after the first hook member 4 and the second hook member 6 are hooked to each other, not only the first and second hook members 4 and 6 are effectively prevented from being displaced up and down and left and right with respect to each other to provide an excellent fitting degree, but also the hook-to-hook mechanical surface adhesive fastener 2 of the present invention can provide a larger lateral pulling force and peel strength than the conventional hook-and-loop mechanical surface adhesive fastener.
The invention is based on the technical idea different from the traditional hook and loop type mechanical surface bonding buckle, not only effectively overcomes the defects of the traditional hook and loop type mechanical surface bonding buckle, but also achieves the effect superior to the traditional technology, therefore, the invention is obviously an innovative creation with industrial applicability.
Although the hook-to-hole mechanical surface bonding fastener 1 and the hook-to-hook mechanical surface bonding fastener 2 of the present invention have been described above with reference to the preferred embodiments shown in the drawings, it is not intended that the present invention be limited to the structures and steps described above and shown in the drawings. Indeed, various modifications may be made to the invention in light of the above teachings. For example, the engaging holes 31 can be arranged in a plurality of rows and the engaging holes in two adjacent rows are arranged in a staggered arrangement, as shown in FIG. 7. Besides, the hooks 42 and 62 can be straight cylindrical hooks as shown in the drawings, or tapered cylindrical hooks with a narrow top and a wide bottom. All these and other possible modifications and variations fall within the scope of protection of the invention, as defined by the following claims.
