The drawings of the present disclosure are provided only for simple illustrations, but are not drawn to scale and do not reflect the actual relative dimensions. The following embodiments are provided to describe in detail the concept of the present disclosure, and are not intended to limit the scope thereof in any way.
- Referring to
FIG. 1 toFIG. 8 , one of the embodiments of the present disclosure provides a sliding assembly 1 (such as a sliding head or a slide fastener head), and thesliding assembly 1 includes abase portion 10, a firstlateral wall portion 11, a secondlateral wall portion 12, aseat portion 13, a retaining member 14 (such as a hook body or a horse-like hook), and anelastic member 15. Thebase portion 10, the firstlateral wall portion 11, the secondlateral wall portion 12 and theseat portion 13 are mated with each other to form a sliding member A. - Referring to
FIG. 1 ,FIG. 7 andFIG. 8 , the firstlateral wall portion 11 and the secondlateral wall portion 12 extend respectively upwardly from two opposite lateral sides of thebase portion 10, and the firstlateral wall portion 11 and the secondlateral wall portion 12 correspond to each other and are connected to afront side portion 101 of thebase portion 10. In addition, theseat portion 13 is disposed on thebase portion 10 and is connected to arear side portion 102 of thebase portion 10, and theseat portion 13 has a positioning throughhole 130 formed between the firstlateral wall portion 11 and the secondlateral wall portion 12. Moreover, theelastic member 15 is disposed on theseat portion 13 to elastically abut against theretaining member 14, and theelastic member 15 has afixing portion 151 fixed on theseat portion 13, anelastic portion 152 extending from thefixing portion 151, and anabutting portion 153 extending from theelastic portion 152 for abutting against the retainingmember 14. Furthermore, the retainingmember 14 is movably disposed on theseat portion 13 for movably contacting the abuttingportion 153 of theelastic member 15, and the retainingmember 14 has apositioning portion 140 disposed on an end portion thereof for passing through the positioning throughhole 130, and the retainingmember 14 has a retainingportion 141 disposed on another end thereof. - Referring to
FIG. 1 ,FIG. 2 andFIG. 8 , theseat portion 13 has at least oneretaining block 133 and at least one through opening 134 adjacent to the at least oneretaining block 133, and the at least oneretaining block 133 has aninner surface 1330 extending inwardly from aninner surface 13002 of theseat portion 13. In addition, theinner surface 1330 of the at least oneretaining block 133 is inclined at an adjustable angle θ relative to theinner surface 13002 of theseat portion 13, and the at least oneretaining block 133 has atop side surface 1331, abottom side surface 1332 opposite to thetop side surface 1331, and afront surface 1333 connected between thetop side surface 1331 and thebottom side surface 1332. Therefore, theretaining portion 141 can be restricted or limited by thebottom side surface 1332 of the at least oneretaining block 133 and can be movably retained on a predetermined plane without being changed by a change of the adjustable angle θ. That is to say, no matter how the adjustable angle θ is adjusted or changed (for example, the adjustable angle θ would be adjusted or changed by a too small or too large punching force), theretaining portion 141 can be restricted by thebottom side surface 1332 of the at least oneretaining block 133 and can be movably retained on a predetermined plane without being changed by a change of the adjustable angle θ (that is to say, the retainingportion 141 can continuously contact thebottom side surface 1332 of the at least oneretaining block 133 and can be rotated relative to theinner surface 13002 of the seat portion 13), so that theretaining portion 141 cannot be offset when the adjustable angle θ is adjusted or changed due to the adjustable angle θ being changed or adjusted on a horizontal plane (not on a vertical plane). - For example, as shown in
FIG. 2 , theseat portion 13 has at least oneouter groove 13A formed on anouter surface 13001 thereof, theseat portion 13 has at least oneinner groove 13B formed on theinner surface 13002 thereof, and the at least oneretaining block 133 extends inwardly from the at least oneouter groove 13A and the at least oneinner groove 13B. In other words, the at least oneouter groove 13A and the at least oneinner groove 13B can be respectively formed on theouter surface 13001 and theinner surface 13002 of theseat portion 13 in advance, so that the thickness between theouter surface 13001 and theinner surface 13002 of theseat portion 13 can be decreased. Therefore, the at least oneretaining block 133 and the at least one through opening 134 can be concurrently formed by a dotting or punching machine easily due to the decreased thickness between theouter surface 13001 and theinner surface 13002 of theseat portion 13. However, the foregoing example is not meant to limit the scope of the present disclosure. For another example, the at least oneinner groove 13B can be omitted, so that the at least oneretaining block 133 only extends inwardly from the at least oneouter groove 13A. Alternatively, the at least oneouter groove 13A can be omitted, so that the at least oneretaining block 133 only extends inwardly from the at least oneinner groove 13B. - It should be noted that a thickness h2 of the
elastic portion 152 is smaller than a thickness h1 of the fixingportion 151 as shown inFIG. 4 , such that an elastic coefficient and an elastic force provided by theelastic portion 152 can be increased. Therefore, theelastic portion 152 can avoid causing elastic fatigue and plastic deformation so as to increase the usage life of theelastic member 15. In addition, referring toFIG. 4 ,FIG. 6 andFIG. 8 , the abuttingportion 153 has aninclined chamfer 1530 formed on an end thereof for slidably contacting the retainingmember 14 so as to increase a contact area between the abuttingportion 153 and the retainingmember 14. - More particularly, referring to
FIG. 1 ,FIG. 5 andFIG. 6 , the fixingportion 151 has afront fixing section 1511, arear fixing section 1512 connected to theelastic portion 152, and amiddle fixing section 1513 connected between thefront fixing section 1511 and therear fixing section 1512. With regard to a width of theelastic member 15, as shown inFIG. 5 , a width W12 of therear fixing section 1512 is smaller than a width W11 of thefront fixing section 1511, and a width W13 of themiddle fixing section 1513 is decreased gradually from thefront fixing section 1511 to therear fixing section 1512. As shown inFIG. 6 , a width W2 of theelastic portion 152 is much smaller than the width W12 of therear fixing section 1512, such that an elastic coefficient and an elastic force provided by theelastic portion 152 can be increased. Therefore, theelastic portion 152 can avoid causing elastic fatigue and plastic deformation so as to increase the usage life of theelastic member 15. In addition, a width W3 of the abuttingportion 153 is larger than a width W2 of theelastic portion 152 so as to increase a contact area between theelastic member 15 and the retainingmember 14. - More particularly, referring to
FIG. 1 andFIG. 4 , therear fixing section 1512 has afirst fixing section 15121 connected to themiddle fixing section 1513 and asecond fixing section 15122 connected between thefirst fixing section 15121 and theelastic portion 152. With regard to a thickness of theelastic member 15, as shown inFIG. 4 , a thickness h2 of theelastic portion 152 is smaller than a thickness h11 of thefirst fixing section 15121 and a thickness h12 of thesecond fixing section 15122 of therear fixing section 1512, and the thickness h12 of thesecond fixing section 15122 is decreased gradually from thefirst fixing section 15121 to theelastic portion 152. In addition, a thickness h2 of theelastic portion 152 and a thickness h3 of the abuttingportion 153 are substantially the same. - More particularly, referring to
FIG. 1 andFIG. 3 , theseat portion 13 has afront retaining section 1301 for fixing thefront fixing section 1511, arear retaining section 1302 for fixing therear fixing section 1512, and amiddle retaining section 1303 connected between thefront retaining section 1301 and therear retaining section 1302 for fixing themiddle fixing section 1513. In addition, as shown inFIG. 3 , a width W2′ of therear retaining section 1302 is smaller than a width W1′ of thefront retaining section 1301, and a width W3′ of themiddle retaining section 1303 is decreased gradually from thefront retaining section 1301 to therear retaining section 1302. The width W3′ of themiddle retaining section 1303 and the width W2′ of therear retaining section 1302 are smaller than the width W1′ of thefront retaining section 1301, so that the friction force between theseat portion 13 and a piece of clothing can be decreased so as to increase the smooth level of the slidingassembly 1 slidably mated with the clothing. - More particularly, referring to
FIG. 7 andFIG. 8 , the retainingportion 141 in afirst receiving groove 131 can be restricted or limited by thebottom side surface 1332 of the at least one retainingblock 133 and can be movably retained on a predetermined plane, so that the retainingmember 14 can be moved upwardly (as shown inFIG. 11 ) or downwardly (as shown inFIG. 10 ) relative to the retainingportion 141 as a rotating shaft or a rotation axis. - Referring to
FIG. 1 andFIG. 9 toFIG. 11 , one of the embodiments of the present disclosure provides a zipper head assembly structure Z. The zipper head assembly structure Z includes a slidingassembly 1 and a pulling member 2 (such as a pull tab or a pull piece). The slidingassembly 1 includes abase portion 10, a firstlateral wall portion 11, a secondlateral wall portion 12, aseat portion 13, a retainingmember 14 and anelastic member 15. The firstlateral wall portion 11 and the secondlateral wall portion 12 extend respectively upwardly from two opposite lateral sides of thebase portion 10, and the firstlateral wall portion 11 and the secondlateral wall portion 12 correspond to each other and are connected to afront side portion 101 of thebase portion 10. In addition, theseat portion 13 is disposed on thebase portion 10 and is connected to arear side portion 102 of thebase portion 10, and theseat portion 13 has a positioning throughhole 130 formed between the firstlateral wall portion 11 and the secondlateral wall portion 12. Moreover, theelastic member 15 is disposed on theseat portion 13 to elastically abut against the retainingmember 14, and theelastic member 15 has a fixingportion 151 fixed on theseat portion 13, anelastic portion 152 extending from the fixingportion 151, and anabutting portion 153 extending from theelastic portion 152 for abutting against the retainingmember 14. Furthermore, the retainingmember 14 is movably disposed on theseat portion 13 for movably contacting the abuttingportion 153 of theelastic member 15, and the retainingmember 14 has apositioning portion 140 disposed on an end portion thereof for passing through the positioning throughhole 130. In addition, the pullingmember 2 is movably mated with the retainingmember 14, for example, the pullingmember 2 includes amovable piece 21 disposed on anend portion 20 thereof for movably mating with the retainingmember 14. - Referring to
FIG. 12 toFIG. 19 , one of the embodiments of the present disclosure provides a sliding assembly 1 (such as a sliding head or a slide fastener head), and the slidingassembly 1 includes abase portion 10, a firstlateral wall portion 11, a secondlateral wall portion 12, aseat portion 13, a retaining member 14 (such as a hook body or a horse-like hook), and anelastic member 15. Thebase portion 10, the firstlateral wall portion 11, the secondlateral wall portion 12 and theseat portion 13 are mated with each other to form a sliding member A. - Referring to
FIG. 12 ,FIG. 18 andFIG. 19 , the firstlateral wall portion 11 and the secondlateral wall portion 12 extend respectively upwardly from two opposite lateral sides of thebase portion 10, and the firstlateral wall portion 11 and the secondlateral wall portion 12 correspond to each other and are connected to afront side portion 101 of thebase portion 10. In addition, theseat portion 13 is disposed on thebase portion 10 and is connected to arear side portion 102 of thebase portion 10, and theseat portion 13 has a positioning throughhole 130 formed between the firstlateral wall portion 11 and the secondlateral wall portion 12. Moreover, theelastic member 15 is disposed on theseat portion 13 to elastically abut against the retainingmember 14, and theelastic member 15 has afirst fixing portion 151 fixed on theseat portion 13, asecond fixing portion 154 fixed on theseat portion 13, an exposedportion 155 connected between thefirst fixing portion 151 and thesecond fixing portion 154 and exposed out of the seat portion 13 (or exposed from the seat portion 13), anelastic portion 152 extending from thefirst fixing portion 151, and anabutting portion 153 extending from theelastic portion 152 for abutting against the retainingmember 14. Furthermore, the retainingmember 14 is movably disposed on theseat portion 13 for movably contacting the abuttingportion 153 of theelastic member 15, and the retainingmember 14 has apositioning portion 140 disposed on an end portion thereof for passing through the positioning throughhole 130. It should be noted that the retainingmember 14 has a uniform thickness H, and thepositioning portion 140 of the retainingmember 14 has a cutting edge 1400 (such as a cutting plane) formed on a lateral surface thereof. - Referring to
FIG. 12 ,FIG. 13 andFIG. 19 , theseat portion 13 has at least one retainingblock 133 and at least one throughopening 134 adjacent to the at least one retainingblock 133, and the at least one retainingblock 133 has aninner surface 1330 extending inwardly from aninner surface 13002 of theseat portion 13. In addition, theinner surface 1330 of the at least one retainingblock 133 is inclined at an adjustable angle θ relative to theinner surface 13002 of theseat portion 13, and the at least one retainingblock 133 has atop side surface 1331, abottom side surface 1332 opposite to thetop side surface 1331, and afront surface 1333 connected between thetop side surface 1331 and thebottom side surface 1332. Therefore, the retainingportion 141 can be restricted or limited by thebottom side surface 1332 of the at least one retainingblock 133 and can be movably retained on a predetermined plane without being changed by a change of the adjustable angle θ. That is to say, no matter how the adjustable angle θ is adjusted or changed (for example, the adjustable angle θ would be adjusted or changed by a too small or too large punching force), the retainingportion 141 can be restricted by thebottom side surface 1332 of the at least one retainingblock 133 and can be movably retained on a predetermined plane without being changed by a change of the adjustable angle θ (that is to say, the retainingportion 141 can continuously contact thebottom side surface 1332 of the at least one retainingblock 133 and can be rotated relative to theinner surface 13002 of the seat portion 13), so that the retainingportion 141 cannot be offset when the adjustable angle θ is adjusted or changed due to the adjustable angle θ being changed or adjusted on a horizontal plane (not on a vertical plane). - For example, as shown in
FIG. 13 , theseat portion 13 has at least oneouter groove 13A formed on anouter surface 13001 thereof, theseat portion 13 has at least oneinner groove 13B formed on theinner surface 13002 thereof, and the at least one retainingblock 133 extends inwardly from the at least oneouter groove 13A and the at least oneinner groove 13B. In other words, the at least oneouter groove 13A and the at least oneinner groove 13B can be respectively formed on theouter surface 13001 and theinner surface 13002 of theseat portion 13 in advance, so that the thickness between theouter surface 13001 and theinner surface 13002 of theseat portion 13 can be decreased. Therefore, the at least one retainingblock 133 and the at least one throughopening 134 can be concurrently formed by a dotting or punching machine easily due to the decreased thickness between theouter surface 13001 and theinner surface 13002 of theseat portion 13. However, the foregoing example is not meant to limit the scope of the present disclosure. For another example, the at least oneinner groove 13B can be omitted, so that the at least one retainingblock 133 only extends inwardly from the at least oneouter groove 13A. Alternatively, the at least oneouter groove 13A can be omitted, so that the at least one retainingblock 133 only extends inwardly from the at least oneinner groove 13B. - It should be noted that a thickness h2 of the
elastic portion 152 is smaller than a thickness h1 of thefirst fixing portion 151 as shown inFIG. 15 , such that an elastic coefficient and an elastic force provided by theelastic portion 152 can be increased. Therefore, theelastic portion 152 can avoid causing elastic fatigue and plastic deformation so as to increase the usage life of theelastic member 15. In addition, the thickness h1 of thefirst fixing portion 151, a thickness h4 of thesecond fixing portion 154, and a thickness h5 of the exposedportion 155 are substantially the same, and the abuttingportion 153 has aninclined chamfer 1530 formed on an end thereof. - More particularly, referring to
FIG. 12 ,FIG. 16 andFIG. 17 , thefirst fixing portion 151 has afront fixing section 1511, arear fixing section 1512 connected to theelastic portion 152, and amiddle fixing section 1513 connected between thefront fixing section 1511 and therear fixing section 1512. With regard to a width of theelastic member 15, as shown inFIG. 16 , a width W12 of therear fixing section 1512 is smaller than a width W11 of thefront fixing section 1511, and a width W13 of themiddle fixing section 1513 is decreased gradually from thefront fixing section 1511 to therear fixing section 1512. As shown inFIG. 17 , a width W2 of theelastic portion 152 is much smaller than the width W12 of therear fixing section 1512, such that an elastic coefficient and an elastic force provided by theelastic portion 152 can be increased. Therefore, theelastic portion 152 can avoid causing elastic fatigue and plastic deformation so as to increase the usage life of theelastic member 15. In addition, as shown inFIG. 17 , a width W3 of the abuttingportion 153 is larger than or substantially equal to a width W2 of theelastic portion 152. When the width W3 of the abuttingportion 153 is larger than the width W2 of theelastic portion 152, a contact area between theelastic member 15 and the retainingmember 14 is increased. It should be noted that the width W3 of the abuttingportion 153 and a width W5 of the exposedportion 155 are substantially the same, and a width W4 of thesecond fixing portion 154 is a decreased width as shown inFIG. 16 andFIG. 17 . - More particularly, referring to
FIG. 12 andFIG. 15 , therear fixing section 1512 has afirst fixing section 15121 connected to themiddle fixing section 1513 and asecond fixing section 15122 connected between thefirst fixing section 15121 and theelastic portion 152. With regard to a thickness of theelastic member 15, as shown inFIG. 15 , a thickness h2 of theelastic portion 152 is smaller than a thickness h11 of thefirst fixing section 15121 and a thickness h12 of thesecond fixing section 15122 of therear fixing section 1512, and the thickness h12 of thesecond fixing section 15122 is decreased gradually from thefirst fixing section 15121 to theelastic portion 152. In addition, a thickness h2 of theelastic portion 152 and a thickness h3 of the abuttingportion 153 are substantially the same. - More particularly, referring to
FIG. 12 ,FIG. 14 andFIG. 18 , theseat portion 13 has afront retaining section 1301 for fixing thefront fixing section 1511, arear retaining section 1302 for fixing therear fixing section 1512, and amiddle retaining section 1303 connected between thefront retaining section 1301 and therear retaining section 1302 for fixing themiddle fixing section 1513. In addition, as shown inFIG. 14 , a width W2′ of therear retaining section 1302 is smaller than a width W1′ of thefront retaining section 1301, and a width W3′ of themiddle retaining section 1303 is decreased gradually from thefront retaining section 1301 to therear retaining section 1302. The width W3′ of themiddle retaining section 1303 and the width W2′ of therear retaining section 1302 are smaller than the width W1′ of thefront retaining section 1301, so that the friction force between theseat portion 13 and a piece of clothing can be decreased so as to increase the smooth level of the slidingassembly 1 slidably mated with the clothing. It should be noted that theseat portion 13 has anauxiliary retaining section 1304 separated from thefront retaining section 1301 for fixing thesecond fixing portion 154 as shown inFIG. 14 andFIG. 18 . - More particularly, the retaining
portion 141 in afirst receiving groove 131 can be restricted or limited by thebottom side surface 1332 of the at least one retainingblock 133 and can be movably retained on a predetermined plane, so that the retainingmember 14 can be moved upwardly (as shown inFIG. 22 ) or downwardly (as shown inFIG. 21 ) relative to the retainingportion 141 as a rotating shaft or a rotation axis. In addition, thesecond fixing portion 154 has a retainingbody 1540 retained inside asecond receiving groove 132. - Referring to
FIG. 12 ,FIG. 20 toFIG. 22 , one of the embodiments of the present disclosure provides a zipper head assembly structure Z including a slidingassembly 1 and a pulling member 2 (such as a pull tab or a pull piece). The slidingassembly 1 includes abase portion 10, a firstlateral wall portion 11, a secondlateral wall portion 12, aseat portion 13, a retainingmember 14 and anelastic member 15. The firstlateral wall portion 11 and the secondlateral wall portion 12 extend respectively upwardly from two opposite lateral sides of thebase portion 10, and the firstlateral wall portion 11 and the secondlateral wall portion 12 correspond to each other and are connected to afront side portion 101 of thebase portion 10. In addition, theseat portion 13 is disposed on thebase portion 10 and is connected to arear side portion 102 of thebase portion 10, and theseat portion 13 has a positioning throughhole 130 formed between the firstlateral wall portion 11 and the secondlateral wall portion 12. Moreover, theelastic member 15 is disposed on theseat portion 13 to elastically abut against the retainingmember 14, and theelastic member 15 has afirst fixing portion 151 fixed on theseat portion 13, asecond fixing portion 154 fixed on theseat portion 13, an exposedportion 155 connected between thefirst fixing portion 151 and thesecond fixing portion 154 and exposed out of theseat portion 13, anelastic portion 152 extending from thefirst fixing portion 151, and anabutting portion 153 extending from theelastic portion 152 for abutting against the retainingmember 14. Furthermore, the retainingmember 14 is movably disposed on theseat portion 13 for movably contacting the abuttingportion 153 of theelastic member 15, and the retainingmember 14 has apositioning portion 140 disposed on an end portion thereof for passing through the positioning throughhole 130. In addition, the pullingmember 2 is movably mated with the retainingmember 14, for example, the pullingmember 2 includes amovable piece 21 disposed on anend portion 20 thereof for movably mating with the retainingmember 14. - Therefore, the
first fixing portion 151 and thesecond fixing portion 154 of theelastic member 15 are fixed on theseat portion 13, so that the bonding strength between theelastic member 15 and theseat portion 13 can be increased so as to prevent the pullingmember 2 from being separated from the slidingassembly 1. - Moreover, the elastic coefficient and the elastic force provided by the
