1. Field of the Invention
The present invention relates generally to a clamping device, and more particularly to a clamping device with auxiliary functions so that the clamping device is capable of clamping an electronic device, like a smart phone, and capable of providing auxiliary functions, like serving as a phone photo-taking selfie.
2. The Prior Arts
Using a smart phone, a tablet computer, a navigation device, taking photo with the smart phones, surfing the Internet, watching movies, and vehicle navigation over the smart phones are common jobs done by majority of people nowadays. Regarding this matter, there are a lot of related assistive tools, such as a phone photo-taking selfie, a tripod or a hanging device that has a clamping device for clamping a smart phone and together with other assistant instruments to facilitate in taking one's own photo with the smart phone. For instance, a conventional phone photo-taking selfie includes a clamping member and a retractable rod unit mounted at a rear side surface of the clamping member in order to adjust the distance between the smart phone and the phone user so as to facilitate in taking one's own photograph. The conventional phone photo-taking selfie further includes a base member that is fixed at a bottom of the clamping member and that holds the smart phone at a horizontal position such that the user can easily surf the Internet or watch a movie in the display panel of the smart phone, thereby eliminating the problem of holding the smart phone by a user hand. The hanging device generally includes an engagement groove. A hook connected to a suction cup inserts into the engagement groove and the suction cup is adapted to be press-fitted onto a windscreen of a car so that the driver can hang his smart phone on the hanging device once the smart phone is switched to a navigation mode for providing guiding information or the traveling route.
It is noted that the majority of presently available assistive tools each provides a single function only. In other words, each assistive tool fails to provide multiple functions, like taking one's own photo, supporting the smart phone at a desired angle to facilitate watching by the user or sticking the smart phone on a windscreen of a car for serving as navigation system.
To be more specific, the conventional phone photo-taking selfie includes a single retractable rod such that the retractable rod can not hold the smart phone at a horizontal position. In addition, the retractable rod is mounted at a rear side surface of the clamping member and in case the rear side surface thereof is formed with an engagement groove, the retractable rod may cover the engagement groove and may prevent mounting of the suction cup in the groove such that the smart phone cannot be fixed on the suction cup.
In the event that the retractable rod is mounted to the base member, the former fails to provide the supporting function. Moreover, if an engagement groove is formed on the rear side surface of the clamping member, a fixed angle will be formed between the base member and the clamping member owing to integrally formation between the two, in which, the base member prevents attachment of the hook and the suction cup with respect to the engagement groove. Under this condition, the suction cup cannot be press-fitted onto the windscreen of a car.
Whether a retractable rod is disposed at the rear side surface of the clamping member or a base member is attached to a lower portion of the clamping member, said retractable rod or said base member prevents attachment of the hook and the suction cup with respect to the engagement groove, which in turn, causes the suction cup unable to be press-fitted onto the windscreen of a car.
A primary objective of the present invention is to provide a clamping device having a telescopic structure provided with auxiliary functions, such as support and retractable-extending features so as not to interfere with the hanging member fixed to a suction cup and the hook member of a clamp seat, thereby facilitating the user in taking a photo by himself.
A clamping device with auxiliary functions of the present invention according includes a pivot seat, a clamp seat and a telescopic structure.
The clamp seat is used for clamping an object thereon and is formed a hook member, and has a lower portion connected pivotally to the pivot seat.
The telescopic structure is disposed behind the clamp seat, defines a hollow space corresponding to the hook member of the clamp seat, and includes two retractable rod units. Each retractable rod unit includes a first retractable rod having a first end connected pivotally to the pivot seat and a second retractable rod connected movably to the first retractable rod such that the second retractable rod is movable relative to the first retractable rod between a retractable position, in which, the first retractable rods are accommodated within the second retractable rods and an extended position, in which, the first retractable rods are exposed at least partially to exteriors of the second retractable rods.
In one embodiment of the present invention, the clamp seat includes a primary plate, a clamping block, a back plate and a spring. The primary plate has a front side surface formed with two support stubs projecting frontward and a rear side surface formed with the lower portion and two pivot lugs projecting rearward for connecting pivotally to the pivot seat. The clamping block includes a movable plate disposed movably between the primary plate and the back plate and a clamping plate disposed atop the movable plate in such a manner to extend transversely, frontwardly beyond a top end of the primary plate. The back plate has a rear side surface formed with the hook member. The spring is disposed between the movable plate and the back plate, and has two opposite ends respectively connected to the movable plate and the back plate. Preferably, the rear side surface of the primary plate is formed with an insert hole. The back plate has a front side surface formed with an insert stick for extending into the insert hole in the primary plate. The movable plate has a rear side surface formed with a hook for engagement with one end of the spring while another end thereof is engaged to the insert stick of the back plate. To be more specific, the movable plate has a lower portion formed with an opening to permit extension of the insert stick of the back plate while the movable plate is disposed movably between the primary plate and the back plate. The clamp seat further includes four cushioning pads, one is disposed on the front side surface of the primary plate, two are disposed on the support stubs of the primary plate while one is disposed at a lower surface of the clamping plate in front of the movable plate.
According to the present invention, the hook member of the back plate is configured as an engagement channel. The engagement channel preferably includes a dented potion and an opening portion connected spatially to the dented portion and extending through the back plate. The opening portion has a dimension smaller than the dented portion such that the dented portion and the opening portion are configured as T-shape.
In one embodiment of the present invention, each of the two second retractable rods defines a first-rod reception channel such that when the second retractable rods are moved to the retractable position, the first retractable rods are accommodated within the first-rod reception channels in the second retractable rods and that when the second retractable rods are moved to the extended position, the first retractable rods are exposed at least partially to the exteriors of the second retractable rods. Each retractable rod unit further includes a third retractable rods connected telescopically to the first and second retractable rods. To be more specific, each of the two third retractable rods defines a second-rod reception channel such that when the second and third retractable rods are moved to the retractable position, the first retractable rods are accommodated within the second-rod reception channels in the third retractable rods while the third retractable rods are accommodated with the first-rod reception channels in the second retractable rods, and when the second and third retractable rods are moved to the extended position, the first retractable rods are exposed at least partially to the exteriors of the third retractable rods while the third retractable rods are exposed at least partially to the exteriors of the second retractable rods.
According to an embodiment of the present invention, the telescopic structure further includes a handgrip defining two parted rod-reception channels for receiving the two second retractable rods therein. Preferably, the handgrip includes a handgrip body formed with the two parted rod-reception channels and the hollow space, two covers respectively covering the two parted rod-reception channels and formed with two positioning holes, and two fasteners extending through two positioning holes in the two second retractable rods and the two positioning holes in the two covers, thereby fixing the two second retractable rods in the two parted rod-reception channels.
