DETAILED DESCRIPTION OF THE INVENTION

[0095] To facilitate understanding of the object, characteristics and effects of this present disclosure, embodiments together with the attached drawings for the detailed description of the present disclosure are provided.

[0096] Referring to FIG. 1 through FIG. 5, a fastener structure 1 of the present disclosure essentially comprises a head portion 11, a rod member 12 and a fitting member 13.

[0097] The head portion 11 has a receiving portion 111 and a holding portion 112. The head portion 11 is round, handle-shaped, drop-shaped, wing-shaped, polyhedral, step-shaped or flaring, as needed.

[0098] The rod member 12 has an engaging portion 121 and an attaching portion 122. The rod member 12 is penetratingly disposed at the receiving portion 111 and causes the attaching portion 122 to correspond in position to the holding portion 112. The engaging portion of the rod member is a cylindrical member, thread member, outer engaging member or inner engaging member as needed.

[0099] The fitting member 13 is penetratingly disposed at the attaching portion 122 and the holding portion 112. The fitting member is a rod member, engaging member, resilient member or expanding member.

[0100] The receiving portion 111 of the head portion 11 is a vertical, transverse or lateral penetrating hole or recess portion. The holding portion 112 of the head portion 11 and the attaching portion 122 of the rod member 12 are lateral, vertical or transverse penetrating holes or recess portions. In this embodiment, the holding portion 112 of the head portion 11 and the attaching portion 122 of the rod member 12 are lateral penetrating holes.

[0101] The fastener structure 1 further comprises a body portion 14 movably fitted to the head portion 11. The body portion 14 has a fitting portion 141. The outer diameter of the fitting portion 141 is greater than, less than or equal to the outer diameter of the head portion 11. The head portion 11 and the body portion 14 have checking portions 113, 142, respectively, for checking and being fitted to each other. The fastener structure 1 further has a resilient component 15 for use in movable fitting or fixed fitting.

[0102] Assembly of the fastener structure 1 at least requires the following steps:

[0103] Step 1: inserting the rod member 12 into the receiving portion 111 of the head portion 11.

[0104] Step 2: aligning the attaching portion 122 of the rod member 12 with the holding portion 112 of the head portion 11.

[0105] Step 3: inserting fitting member 13 into the holding portion 112 and the attaching portion 122, such that the fitting member 13 fits the head portion 11 and the rod member 12 together.

[0106] Mounting the body portion 14 in place requires the checking portion 142 of the body portion 14 and the checking portion 113 of the head portion 11 (or rod member 12) to check each other, such that the body portion 14 is movably fitted to the head portion 11. Before the head portion 11 and the rod member 12 are mounted in place, or before the body portion 14 and the head portion 11 are mounted in place, the resilient component 15 is fitted around the rod member 12, such that the resilient component 15 has one end abutting against the body portion 14 and the other end abutting against the engaging portion 121 of the rod member 12.

[0107] Starting to use the fastener structure entails fitting the fitting portion 141 of the body portion 14 to a first object 2 by riveting, expanding, welding, fastening, adhering or soldering, or allowing the fitting portion 141 of the body portion 14 to be integrally formed with the first object 2. Then, the user exerts a pulling force on the head portion 11, such that the head portion 11 drives the engaging portion 121 of the rod member 12 upward to thereby compress the resilient component 15. After that, the user places a second object 3 on the first object 2 and then releases the head portion 11, such that the resilient component 15 is released to thereby push the engaging portion 121 (and drive the head portion 11); thus, the engaging portion 121 of the rod member 12 penetrates the first object 2 before being fastened to the second object 3.

[0108] To unfasten the first object 2 and the second object 3, the user pulls the head portion 11 again, such that the head portion 11 drives the engaging portion 121 of the rod member 12 upward to thereby compress the resilient component 15. At this point in time, the engaging portion 121 separates from the second object 3, thereby causing separation of the first object 2 and the second object 3. Therefore, the present disclosure achieves quick coupling and easy unfastening.

[0109] Referring to FIG. 6, in this embodiment, a plurality of fastener structures 1 are disposed in a carrier 4, and the carrier 4 has a cover 41. Therefore, storage of the fastener structure 1 is effected.

[0110] Referring to FIG. 7, in this embodiment, the engaging portion 121a of the rod member 12a is an outer thread. The resilient component 15a has one end abutting against the head portion 11a and the other end abutting against the body portion 14a. The checking portion 142a of the body portion 14a and the rod member 12a check each other and is fitted to each other.

[0111] Referring to FIG. 8, in this embodiment, the engaging portion 121b of the rod member 12b is an outer engaging member. The resilient component 15b has one end abutting against the head portion 11b and the other end abutting against the checking portion 142b of the body portion 14b. The checking portion 142b of the body portion 14b and the rod member 12b check each other.

[0112] Referring to FIG. 9, in this embodiment, the engaging portion 121c of the rod member 12c is an inner engaging member. The resilient component 15c has one end abutting against the head portion 11c and the other end abutting against the body portion 14c. The checking portion 113c of the head portion 11c and the checking portion 142c of the body portion 14c check each other. In this embodiment, the checking portion 113c of the head portion 11c and the checking portion 142c of the body portion 14c are engaging members fastened to each other.

[0113] Referring to FIG. 10, in this embodiment, the head portion 11d is a handle, whereas the engaging portion 121d of the rod member 12d is an outer thread. The resilient component 15d has one end abutting against the head portion 11d and the other end abutting against the body portion 14d. The checking portion 142d of the body portion 14d and the rod member 12d check each other.

[0114] Referring to FIG. 11 and FIG. 12, in this embodiment, the checking portion 113e of the head portion 11e is a resilient member and is deformed under an applied force to thereby insertedly engage with the checking portion 142e of the body portion 14e, such that the head portion 11e is movably fitted to the body portion 14e. The top surface of the rod member 12e has a force-applying portion 123e, such that a tool (not shown) can operate. The body portion 14e has an inner thread 143e. The engaging portion 121e is an outer thread. Owing to coordination of the inner thread 143e and the outer thread of the engaging portion 121e, the checking portion 113e of the head portion 11e is insertedly engaged with the checking portion 142e of the body portion 14e.

[0115] Referring to FIG. 13, in this embodiment, two ends of the holding portion 112f of the head portion 11f have recess portions 114f, 115f, respectively. The fitting member 13f has one end having a stopping portion 131f and the other end having an expanding portion 132f. The recess portions 114f, 115f store the stopping portion 131f and the expanding portion 132f at the two ends of the fitting member 13f, respectively.

[0116] Assembly of the fastener structure entails insertedly disposing the rod member 12f in the receiving portion 111f of the head portion 11f to allow the attaching portion 122f of the rod member 12f to correspond in position to the holding portion 112f of the head portion 11f, insertedly disposing the fitting member 13f in the holding portion 112f and the attaching portion 122f, fitting the head portion 11f and the rod member 12f together by the fitting member 13f, blocking the stopping portion 131f of the fitting member 13f by the recess portion 114f of the head portion 11f, and allowing the expanding portion 132 of the fitting member 13f to expand and deform under an applied force expanding so as to be blocked by another recess portion 115f of the head portion 11f.

[0117] Referring to FIG. 14 and FIG. 15, in this embodiment, the head portion 11 further has a handle portion 116 (shown in FIG. 14), or the head portion 11 further has an operating portion 117 (shown in FIG. 15). Therefore, to start using the fastener structure, the handle portion 116 or the operating portion 117 exerts a force on the head portion 11, such that the head portion 11 drives the rod member 12 fastening in place. Therefore, the present disclosure meets practical operation-related and usage-related needs.

[0118] Referring to FIG. 16, in this embodiment, the rod member 12 penetrates and exits an internal hole 144 of the body portion 14, such that the attaching portion 122 penetrates and exits the body portion 14. After the attaching portion 122 has been fitted to the head portion 11, the fitting member 13 is insertedly disposed in the attaching portion 122, such that the rod member 12 is movably fitted to the body portion 14. The head portion 11 has a shoulder space 118. The shoulder space 118 receives a resilient component 15. The rod member 12 is of a width greater than (equal to or less than) the width of a blocking portion 124 of the engaging portion 121. The blocking portion 124 is blocked at an internal hole 144 of the body portion 14, such that the rod member 12 is movably fitted to the body portion 14. Therefore, to start using the fastener structure, the user exerts a force on the head portion 11, such that the head portion 11 drives the engaging portion 121 of the rod member 12 downward to thereby compress the resilient component 15; thus, the engaging portion 121 is fastened to the second object (not shown). To unfasten the engaging portion 121, the user exerts a force on the head portion 11 again, such that the head portion 11 drives the engaging portion 121 of the rod member 12 moving and releases the resilient component 15 to thereby separate the engaging portion 121 from the second object, so as to achieve quick coupling and easy unfastening.

[0119] Referring to FIG. 17, in this embodiment, the body portion 14 has a shoulder space 145. The shoulder space 145 contains a resilient component 15 Therefore, the present disclosure meets practical operation-related and usage-related needs.

[0120] Referring to FIG. 18 and FIG. 19, in this embodiment, the body portion 14 has a pressed portion 146. A tool 5 presses or abuts against the pressed portion 146 under an applied force, such that a fitting portion 147 of the body portion 14 presses a first object 2; thus, the material of the first object 2 enters or flows into a material storage space 1471 of the fitting portion 147 to allow the body portion 14 to be fitted to the first object 2. The body portion 14 is of greater hardness than the first object 2. Therefore, the body portion 14 is firmly fitted to the first object 2 to facilitate subsequent related operation.

[0121] Referring to FIG. 20, in this embodiment, the body portion 14 has a pressed portion 146. A tool 5 presses or abuts against the pressed portion 146 under an applied force, such that a fitting portion 147 of the body portion 14 is expanded and fitted to a first object 2 when pressed by another tool 6 under an applied force, thereby allowing the body portion 14 to be fitted to the first object 2. Therefore, the body portion 14 is firmly fitted to the first object 2 to facilitate subsequent related operation.

[0122] Referring to FIG. 21, in this embodiment, the fastener structure 1 is disposed in a carrier 7. The fastener structure 1 is taken out of the carrier 7 with a tool 8 and then compared with a comparison device 9. After that, the fastener structure 1 is precisely placed on a first object 2 for fitting. In this embodiment, the body portion 14 (or head portion 11) of the fastener structure 1 has a weldable surface 148 weldable to a weldable surface 21 of the first object 2. The weldable surfaces 148, 21 are solder portions between the body portion 14 and the first object 2. The solder portions are heated to change to a liquid state and then cooled to change to a solid state; thus, the body portion 14 and the first object 2 are fitted to each other. The tool 8 is a vacuum suction device or a clamp. The first object is a PCB, a metal board or a plastic board. Therefore, the body portion 14 is firmly fitted to the first object 2 to facilitate subsequent related operation.

[0123] The tool 8 is a vacuum suction device. The head portion 11 is an airtight structure disposed above the rod member 12, such that the fastener structure 1 is attracted to the vacuum suction device by suction.

[0124] Referring to FIG. 22 through FIG. 24, in this embodiment, the fastener structure 1 further comprises a torsion spring 16. The torsion spring 16 has one end blockedly disposed at the head portion 11 and the other end blocked at the body portion 14 (shown in FIG. 22 and FIG. 23). Alternatively, the torsion spring 16 has one end blockedly disposed at the body portion 14 and the other end blocked at the rod member 12 (shown in FIG. 24). Thus, the head portion 11 or the rod member 12 rotates to and fro because of resilience of the torsion spring 16. Therefore, the present disclosure meets practical operation-related and usage-related needs.

[0125] Referring to FIG. 25 and FIG. 26, in this embodiment, the pressed portion 146 is disposed beside the head portion 11, the rod member 12 and the fitting member 13 and is of a greater width than the head portion 11, the rod member 12 and the fitting member 13; thus, the head portion 11 rotates about the fitting member 13 to drive the rod member 12 moving and thereby creating the pressed space of the pressed portion 146. Consequently, a tool 5 presses or abuts against the pressed portion 146 under an applied force, such that a fitting portion 147 of the body portion 14 presses a first object 2. Therefore, the material of the first object 2 enters or flows into a material storage space 1471 of the fitting portion 147, thereby allowing the body portion 14 to be fitted to the first object 2. The body portion 14 is of greater hardness than the first object 2. Therefore, the body portion 14 is firmly fitted to the first object 2 to facilitate subsequent related operation. To operate the fastener structure, the user rotates the head portion 11 about the fitting member 13 to drive the rod member 12 moving and thereby being fastened to the second object or separating therefrom.

[0126] Referring to FIG. 27 and FIG. 29, in this embodiment, the head portion 11 has a blocking portion 119, and the body portion 14 has a corresponding blocking portion 148. The blocking portion 119 and the corresponding blocking portion 148 block each other to limit rotation or lateral movement of the head portion 11. The blocking portion 119 and the corresponding blocking portion 148 are raised portion, dented portion, stepped portion, oblique surface portion, curved surface portion, arcuate surface portion or flatted surface portion Therefore, the present disclosure meets practical operation-related and usage-related needs.

[0127] Refer to FIG. 30 through FIG. 33 which illustrate this embodiment. The head portion 11 has a blocking portion 119. The body portion 14 has a corresponding blocking portion 148. The rod member 12 has a blocking portion 124. The body portion 14 has another corresponding blocking portion 149. The blocking portions 119, 124 and the corresponding blocking portions 148, 149 block each other to limit the rotation or lateral movement of the head portion 11.

[0128] In an embodiment of the present disclosure, the blocking portions 119, 124 are tetrahedrons or polyhedrons, and the corresponding blocking portions 148, 149 are tetrahedrons or polyhedrons (shown in FIG. 30). Alternatively, the blocking portion 119 is a blocking raised member, and the corresponding blocking portion 148 is a corresponding blocking dented member (shown in FIG. 31, FIG. 32). Alternatively, the blocking portion 124 is a blocking dented member, and the corresponding blocking portion 149 is a corresponding blocking raised member (shown in FIG. 33).

[0129] Referring to FIG. 34 through FIG. 40, in this embodiment, the head portion 11 has a tool control portion 10. The tool control portion 10 comprises the rod member 12 and the fitting member 13 (shown in FIG. 37 through FIG. 39). The fastener structure 1 further comprises a tool 101. The tool 101 has a corresponding control portion 102 (shown in FIG. 34 through FIG. 36) corresponding in position to the tool control portion 10 to control the rod member 12 (shown in FIG. 40) of the fastener structure 1. The tool control portion 10 is the space within the head portion 11, disposed on two sides of the fitting member 13, and lower than the upper end of the head portion 11.

[0130] Referring to FIG. 41, in this embodiment, the head portion 11 is formed with a mold 20 by intra-mold injection molding, including plastic intra-mold injection, metal intra-mold injection or nonmetal intra-mold injection. The mold 20 has a sprue 201, a gate 202, an upper mold 203 and a lower mold 204. A mold closing portion 205 is disposed between the upper mold 203 and the lower mold 204. Liquid material is admitted into a hollow intra-mold head portion space 206 from the gate 202 and thus cooled and solidified to form the head portion 11.

[0131] While the present disclosure has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the present disclosure set forth in the claims.
