The present disclosure will now be described with some preferred embodiments thereof and by referring to the accompanying drawings. For the purpose of easy to understand, elements that are the same in the preferred embodiments are denoted by the same reference numerals

Please refer to FIGS. 1 to 6. A fastening device 1 according to a first embodiment of the present disclosure includes at least one base portion 11 and at least one fastener portion 12.

The base portion 11 can be connected to a first object 10.

The fastener portion 12 is slidably assembled to the base portion 11, such that the fastener portion 12 cooperates with the base portion 11 to provide a locking and an unlocking function for connecting or disconnecting a second object 20 to or from the base portion.

To use the fastening device 1 of the first embodiment, first connect the base portion 11 to the first object 10. The first object 10 can be a printed circuit board (PCB). Then, sideward move the fastener portion 12 from a first end to an opposite second end of the base portion 11 and put the second object 20 on the first end of the base portion 11, as shown in FIG. 5. Thereafter, sideward move the fastener portion 12 again toward the second object 20 to lock the second object 20 in place on the base portion 11, as shown in FIG. 6. When it is desired to remove the second object 20 from the base portion 11, simply move the fastener portion 12 sideward again, so that the fastener portion 12 is moved away from the second object 20 to unlock the same. At this point, the second object 20 can be removed from the base portion 11, as shown in FIG. 5. In this manner, when the base portion 11 is connected to the first object 10, the fastener portion 12 cooperates with the base portion 11 to provide a locking and an unlocking function to connect or disconnect the second object 20 to or from the base portion, respectively, enabling two objects to be repeatedly and quickly connected to or disconnected from each other.

In the first embodiment of the present disclosure, the base portion 11 includes at least one connecting section 111, which can be welded to, snapped onto, screwed into, expansion connected to or glued to the first object 10 and therefore connects the base portion 11 to the first object 10. In this manner, the base portion 11 can be securely connected to the first object 10 to facilitate subsequent movement of the fastener portion 12 on and relative to the base portion 11.

In the illustrated first embodiment of the present disclosure, the base portion 11 includes two connecting sections 111, one of which is integrally extended from a bottom of the base portion 11 while the other one of which is additionally connected to the bottom of the base portion 11. In another operable embodiment, both of the two connecting sections 111 are integrally extended from the bottom of the base portion 11. In a further operable embodiment, both of the two connecting sections 111 are additionally connected to the bottom of the base portion 11. With the provision of the connecting sections 111, the base portion 11 can be stably and securely connected to the first object 10 to facilitate subsequent movement of the fastener portion 12 on and relative to the base portion 11.

In the first embodiment of the present disclosure, the base portion 11 is provided at two lateral sides with a slide section 112 each, and the fastener portion 12 is provided at two lateral sides with a corresponding slide section 121 each. The corresponding slide sections 121 are respectively slidably engaged with the slide sections 112, such that the fastener portion 12 is sideward slidably assembled to the base portion 11. The slide sections 112 can be respectively a groove or a guide rail, and the corresponding slide sections 121 can be respectively a guide rail or a groove. Through the slidable engagement of the corresponding slide sections 121 with the slide sections 112, the fastener portion 12 being sideward moved on and relative to the base portion 11 can slide smoothly to advantageously lock or unlock the second object 20.

In the first embodiment of the present disclosure, the base portion 11 is further provided at its two lateral sides with a stop section 113 each, and the fastener portion 12 is provided at its two lateral sides with a corresponding stop section 122 each. The corresponding stop sections 122 are respectively detachably abutted on the stop sections 113, such that the mutually abutted stop sections 113 and corresponding stop sections 122 stop the fastener portion 12 having locked the second object 20 in place from moving relative to the base portion to ensure secured locking of the second object 20 in place by the fastener portion 12.

In the illustrated first embodiment of the present disclosure, either the stop sections 113 or the corresponding stop sections 122 are flexible for snap-fitting. The stop sections 113 or the corresponding stop sections 122 are respectively provided with a beveled slide surface or a curved slide surface, such that the stop sections 113 and the corresponding stop sections 122 are slidable relative to one another. Further, a portion of each of the stop sections 113 or of the corresponding stop sections 122 located immediately opposed to the slide surface is an abutting surface that defines a right angle, a near-right angle, or an angle larger than that defined by the slide surface to facilitate stable abutting of the stop section 113 on the corresponding stop section 122, so that the fastening device 1 of the present disclosure is more practical for use.

In the first embodiment of the present disclosure, the base portion 11 has a resting section 114 provided at the first end thereof and the fastener portion 12 has a fixing section 123 provided at an end corresponding to the first end of the base portion 11, such that the resting section 114 are located corresponding to the fixing section 123. When using the fastening device 1, sideward slide the fastener portion 12 toward the second end of the base portion 11 and place the second object 20 on the resting section 114 of the base portion 11, as shown in FIG. 5, and then sideward slide the fastener portion 12 toward the second object 20, so that the fixing section 123 of the fastener portion 12 locks the second object 20 in place on the resting section 114 to complete the connection of the fastener portion 2 to the second object 20, as shown in FIG. 6. When it is desired to separate the fastener portion 12 from the second object 20, simply sideward slide the fastener portion 12 again toward the second end of the base portion 11 to move the fixing section 123 of the fastener portion 12 away from the second object 20 to unlock the second object 20, and the second object 20 can be now removed from the resting section 114 of the base portion 11, as shown in FIG. 5. In the above manner, the base portion 11 is first connected to the first object 10 and the fastener portion 12 cooperates with the base portion 11 to provide a locking and an unlocking function for locking or unlocking the second object 20, respectively, to the base portion 11. Therefore, two objects can be repeatedly and quickly connected to or disconnected from each other. More particularly, the fixing section 123 of the fastener portion 12 cooperates with the resting section 114 of the base portion 11 to provide the locking and the unlocking function to connect or remove the second object 20 to or from the base portion 11.

In the illustrated first embodiment of the present disclosure, the resting section 114 is a stepped surface, such that a limiting section 13 is formed between the fixing section 123 and the resting section 114. That is, the fixing section 123 cooperates with the resting section 114 to lock the second object 20 to the limiting section 13; or the fixing section 123 is moved away from the resting section 114 to expose the limiting section 13 and allow the second object 20 to be removed from the limiting section 13 of the resting section 114. To use the fastening device 1, first sideward slide the fastener portion 12 from the first end to the second end of the base portion 11 and place the second object 20 on the resting section 114 of the base portion 11, as shown in FIG. 5, and then sideward slide the fastener portion 12 toward the second object 20 until the fixing section 123 of the fastener portion 12 locks the second object 20 in place in the limiting section 13, as shown in FIG. 6. At this point, the connection of the fastener portion 12 to the second object 20 is completed. When it is desired to remove the second object 20 from the fastening device 1, simply sideward slide the fastener portion 12 toward the second end of the base portion 11 to move the fixing section 123 away from the limiting section 13. At this point, the limiting section 13 is exposed and in an open state, so that the second object 20 can be removed from the resting section 114 of the base portion 11, as shown in FIG. 5. Thus, the base portion 11 can be first connected to the first object 10, and the fastener portion 12 can cooperate with the base portion 11 to provide a locking and an unlocking function to lock or unlock the second object 20 to or from the base portion 11, so as to achieve quick and repeated connection or disconnection of two objects to or from each other. More specifically, the fixing section 123 of the fastener portion 12 cooperates with the resting section 114 of the base section 11 to provide the locking and unlocking function for connecting or disconnecting the second object 20 to or from the base portion 11.

In the first embodiment of the present disclosure, the fastener portion 12 is provided with an operating section 124 for operating and controlling the fastener portion 12 to sideward slide or pivot on and relative to the base portion 11. The operating section 124 is located at an end of the fastener portion 12 and includes an anti-slip section 125. To control the movement of the fastener portion 12 on the base portion 11, simply apply a force to the anti-slip section 125 of the operating section 124. In this manner, the force can be stably applied to the operating section 124, enabling the fastener portion 12 to cooperate with the base portion 11 to provide the locking and the unlocking function. Thus, the fastener portion 12 can lock or unlock the second object 20 to or from the base portion 11 to achieve quick and repeated connection or disconnection of two objects to or from each other.

In the first embodiment of the present disclosure, the base portion 11 and the fastener portion 12 have an elastic element 14 disposed between them. The elastic element 14 has an end pressed against the base portion 11 and another end pressed against the fastener portion 12, so that the fastener portion 12 is normally pushed by the elastic element 14 to a locking position. Alternatively, in another operable embodiment, the fastener portion 12 is normally pushed by the elastic element 14 to an unlocking position.

When using the fastening device 1, a force is applied to the operating section 124 for the fastener portion 12 to slide sideward. At this point, the elastic element 14 is elastically compressed. Then, place the second object 20 on the resting section 114 of the base portion 11 and release the fastener portion 12. At this point, the elastic element 14 releases its elasticity to automatically push the fastener portion 12 sideward to slide toward the second object 20, such that the fixing section 123 of the fastener portion 12 locks the second object 20 in place in the limiting section 13 of the resting section 114 to complete the connection of the fastener portion 12 to the second object 20, as shown in FIG. 6. When it is desired to remove the second object 20, simply sideward slide the fastener portion toward the second end of the base portion 11 again to move the fixing section 123 away from the limiting section 13. At this point, the elastic element 14 is elastically compressed and the limiting section 13 is exposed and in an open state, so that the second object 20 can be removed from the resting section 114 of the base portion 11, as shown in FIG. 5. After removal of the second object 20, release the fastener portion 12. At this point, the elastic element 14 releases it elasticity to automatically move the fastener portion 12 to the locking position, and the fastening device 1 can be used next time. In this manner, the base portion 11 can be first connected to the first object 10, and the fastener portion 12 cooperates with the base portion 11 to provide a locking and an unlocking function for locking or unlocking the second object 20 to or from the base portion 11, so as to achieve quick and repeated connection or disconnection of two objects to or from each other.

The second embodiment is different from the first one in that the slide sections 112 and the corresponding slide sections 121 as well as the stop sections 113 and the corresponding stop sections 122 in the second embodiment are provided on the base portion 11 and the fastener portion 12, respectively, at locations different from that in the first embodiment; and the fastener portion 12 in the second embodiment has the operating section 124 provided on each of two lateral sides thereof.

To use the fastening device 1 of the second embodiment, first apply a force to the operating sections 124 so that the fastener portion 12 is controlled to sideward slide toward the second end of the base portion 11. At this point, the elastic element 14 is compressed. Then, put the second object 20 on the resting section 114 of the base portion 11 and release the fastener portion 12. At this point, the elastic element 14 releases its elasticity to automatically push the fastener portion 12 sideward to slide toward the second object 20, such that the fixing section 123 of the fastener portion 12 locks the second object 20 in place in the limiting section 13 of the resting section 114 to complete the connection of the second object 20 to the base portion 11, as shown in FIG. 6. When it is desired to remove the second object 20, simply sideward slide the fastener portion toward the unlocking position at the second end of the base portion 11 to move the fixing section 123 away from the limiting section 13. At this point, the elastic element 14 is elastically compressed and the limiting section 13 is exposed and in an open state, so that the second object 20 can be removed from the resting section 114 of the base portion 11, as shown in FIG. 5. After removal of the second object 20, release the fastener portion 12. At this point, the elastic element 14 releases it elasticity to automatically move the fastener portion 12 to the locking position, and the fastening device 1 can be used next time. In this manner, the base portion 11 can be first connected to the first object 10, and the fastener portion 12 cooperates with the base portion 11 to provide a locking and an unlocking function to lock or unlock the second object 20 to or from the base portion 11, so as to achieve quick and repeated connection or disconnection of two objects to or from each other.

When the fastener portions 12 are sideward sliding on and relative to the base portion 11, the corresponding slide sections 121 engage with the slide sections 112 to enable smooth sliding of the fastener portions 12. At this point, the elastic elements 14 are compressed. Then, place a second object and a third object (not shown) on the resting sections 114 on the top and the bottom of the base portion 11, respectively, with the fixing sections 123 of the fastener portions 12 directing toward the second and the third object. Thereafter, release the fastener portions 12. At this point, the elastic elements 14 release their elasticity to sideward move the fixing sections 123 of the fastener portions 12 toward the second and the third object until the corresponding stop sections 122 of the fastener portions 12 and the stop sections 113 of the base portion 11 are abutted on one another. At this point, the mutually abutted stop sections 113 and corresponding stop sections 122 stop the fastener portions 12 having moved into the locking portion from moving relative to the base portion 11 to complete the locking of the second and the third object to the base portion 11.

When it is desired to remove the second and the third object, simply sideward slide the fastener portions 12 toward the second end of the base portion 11 again. At this point, the elastic elements 14 are compressed, and the fixing sections 123 of the fastener portions 12 are moved to the unlocking position to unlock the second and the third object, allowing the second and the third object to be removed from the resting sections 114 of the base portion 11. After the second and the third object have been removed, the fastener portions 12 are released and the elastic elements 14 release their elasticity to automatically push the fastener portions 12 to the locking position again for use next time. At this point, the disconnection of the base portion 12 from the second and the third object is completed.
