The drawings of the instant 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 instant disclosure, and are not intended to limit the scope thereof in any way.
Referring to FIG. 1 to FIG. 8, the instant disclosure provides a zipper head assembly structure Z for decreasing assembling resistance, comprising: a sliding member 1 (such as a sliding head or a slide fastener head), a movable cover body 2, and a pull member 3 (such as a pull tab or a pull piece).
First, referring to FIG. 1 and FIG. 2, the sliding member 1 has a first sliding body 11, a second sliding body 12 opposite to the first sliding body 11, and a connection body 13 connected between the first sliding body 11 and the second sliding body 12. More precisely, the sliding member 1 has a first convex body 14 disposed on the first sliding body 11, a second convex body 15 disposed on the first sliding body 11 and corresponding to the first convex body 14, and at least one through opening 16 passing through the first sliding body 11 and disposed between the first convex body 14 and the second convex body 15. In addition, the first convex body 14 has a first main portion 140 disposed on the first sliding body 11, two sliding grooves 141 respectively disposed on two opposite lateral sides of the first main portion 140, and at least one structure reinforcing rib 142 disposed on the first sliding body 11 and connected with the first main portion 140.

Following the above description, for example, the second main portion 150 has a carrier body 1501 and two lateral walls 1502 respectively disposed on two opposite lateral sides of the carrier body 1501. In addition, the carrier body 1501 has a first surface 15011, a second surface 15012 connected with the first surface 15011, a third surface 15013 connected with the second surface 15012, and a fourth surface 15014 connected with the third surface 15013 and disposed on the front side of the second main portion 150. The receiving groove 153 is disposed on the carrier body 1501 and between the two lateral walls 1502, and the two inclined assembly surfaces 152 are respectively inclinedly disposed on the two lateral walls 1502.
Moreover, referring to FIG. 3, FIG. 4, and FIG. 5, the movable cover body 2 is movably disposed on the first sliding body 11, and the pull member 3 has an end portion 30 movably mated with the movable cover body 2. In addition, the movable cover body 2 has a major portion 20, two sliding portions 21 extended outwardly from the major portion 20 and respectively slidably disposed inside the two sliding grooves 141, a positioning portion 22 extended outwardly from the major portion 20 and movably passing through the through opening 16, two pivotal portions 23 extended outwardly from the major portion 20 and respectively pivotally disposed inside the two pivotal grooves 151, an extending tail portion 24 extended outwardly from the major portion 20 and disposed inside the receiving groove 153, and two assembly chamfers 25 (such as two assembly bevels) respectively disposed on two inner corners of the two pivotal portions 23 and respectively corresponding to the two inclined assembly surfaces 152. For example, the inclined assembly surface 152 has a first predetermined inclination such as 45 degrees relative to the horizontal surface, the assembly chamfer 25 has a second predetermined inclination such as 45 degrees relative to the horizontal surface. When the first predetermined inclination is the same as or similar to the second predetermined inclination, the assembling resistance between the assembly chamfer 25 and the inclined assembly surface 152 is decreased. Hence, the two assembly chamfers 25 can respectively slip through the two inclined assembly surfaces 152 easily in order to assemble the movable cover body 2 on the sliding member 1.
More precisely, referring to FIG. 1 and FIG. 2, the major portion 20 has a first plane plate 201 and two second plane plates 202 respectively extended downwardly from the two opposite lateral sides of the first plane plate 201. The two sliding portions 21 are respectively extended outwardly from two first lateral sides 2001 of the two second plane plates 202, the positioning portion 22 is extended downwardly from a bottom side 2000 of one of the two second plane plates 202, the two pivotal portions 23 are respectively extended outwardly from two second lateral sides 2002 of the two second plane plates 202, and the extending tail portion 24 is extended downwardly from an end side of the first plane plate 201.
More precisely, referring to FIG. 1, FIG. 2, FIG. 6, and FIG. 7, the first convex body 14 has two vertical convex ribs 143 respectively disposed inside the two sliding grooves 141, and the two sliding portions 21 respectively movably contact the two vertical convex ribs 143. Referring to FIG. 1, FIG. 2, FIG. 6, and FIG. 8, the second convex body 15 has two first convex points 154 respectively disposed inside the two pivotal grooves 151, and the two pivotal portions 23 respectively movably contact the two first convex points 154. In addition, the second convex body 15 has at least one second convex point 155 disposed inside the receiving groove 153, and the extending tail portion 24 movably contacts the at least one second convex point 155.
Referring to FIG. 9, FIG. 10, and FIG. 11, FIG. 9 shows a partial, lateral, schematic view of the movable cover body 2 of the zipper head assembly structure Z preparing to be assembled on the sliding member 1 (that is to say that the assembly chamfer 25 prepares to contact the inclined assembly surface 152) according to the instant disclosure, FIG. 10 shows a partial, lateral, schematic view of the movable cover body 2 of the zipper head assembly structure Z slipping on the sliding member 1 (that is to say that the assembly chamfer 25 has contacted the inclined assembly surface 152) according to the instant disclosure, and FIG. 11 shows a partial, lateral, schematic view of the movable cover body 2 of the zipper head assembly structure Z having been assembled on the sliding member 1 (that is to say that the assembly chamfer 25 has slipped through the inclined assembly surface 152) according to the instant disclosure. Referring to FIG. 9 and FIG. 10, the assembling resistance of assembling the movable cover body 2 on the sliding member 1 is decreased due to the low-resistance surface contact between the assembly chamfer 25 and the inclined assembly surface 152, so as to prevent the sliding member 1 from being scraped by the movable cover body 2. Hence, the two assembly chamfers 25 can respectively slip through the two inclined assembly surfaces 152 easily in order to assemble the movable cover body 2 on the sliding member 1.
In conclusion, Because the designs of “the two pivotal portions 23 extended outwardly from the major portion 20 and respectively pivotally disposed inside the two pivotal grooves 151” and “the two assembly chamfers 25 respectively disposed on two inner corners of the two pivotal portions 23 and respectively corresponding to the two inclined assembly surfaces 152”, the assembling resistance of assembling the movable cover body 2 on the sliding member 1 is decreased due to the low-resistance surface contact between the assembly chamfer 25 and the inclined assembly surface 152, so as to prevent the sliding member 1 from being scraped by the movable cover body 2.
For example, the inclined assembly surface 152 has a first predetermined inclination such as 45 degrees relative to the horizontal surface, the assembly chamfer 25 has a second predetermined inclination such as 45 degrees relative to the horizontal surface. When the first predetermined inclination is the same as or similar to the second predetermined inclination, the assembling resistance between the assembly chamfer 25 and the inclined assembly surface 152 is decreased. Hence, the two assembly chamfers 25 can respectively slip through the two inclined assembly surfaces 152 easily in order to assemble the movable cover body 2 on the sliding member 1.
