DETAILED DESCRIPTION OF THE INVENTION
The structural features and the effects to be achieved may further be understood and appreciated by reference to the presently preferred embodiments together with the detailed description.
Firstly, referring to FIG. 2, is a three-dimensional view of a preferred embodiment of the present invention. The support comprises a platform 24, a bracket 22, a joint module 26, a sleeve 28, a crooked shaft 29, and a base 27. The Base 27 is locked and fixed on an object 275, such as a stationary frame, a suspensory arm, or a table, and further, the base 27 can slip over an end of the crooked shaft 29, such that the crooked shaft 29 can be rotated with free angle for adjusting positions. An opened end of the sleeve 28 can be slipped over another end of the crooked shaft 29, and the closed end thereof can be connected to the joint module 26. The bracket 22 is connected to the joint module 26, and locked the platform 24 fixedly by a lock module 21, thus, the platform can be used for supporting the keyboard.
The joint module 26 can be used for providing the platform 24 to be adjusted in up/down angle. According to the coordination of the crooked shaft 29 and the sleeve 28, the sleeve 28 can be rotated to adjust the waving angle of the platform 24. And, the slipped section of the crooked shaft 29 and the base 27 can be rotated to adjust the positions. Surely, regarding to above mentioned adjustment, the platform 24 can be easily adjusted in any positions and up/down angle for preventing the waving of the platform 24, such that two ends thereof can be with one horizontal, since which is under operation.
The joint module 26 comprises a joint set 260 and a hinge 236, wherein the joint set 260 is connected with the closed end of the sleeve 28, and the hinge 263 is slipped within the joint set 260. One end of the bracket 22 can be linked with the hinge 263 by the connecting hole 267 provided on the hinge 263. The hinge 263 within the joint set 260 can be rotated with the bracket 22 and the platform 24 following for adjusting the up/down angle of the platform 24.
The joint module 26 further comprises a spiral rod 265, which is pierced through the hole 261 of the joint set 260 and locked with the closed end of the sleeve 28. Besides, The strength of locking the spiral rod 265 can be used to clip the hinge 263 after adjusting the angle of joint set 260. The spiral rod 265 can be selected to be as a quick release spiral rod for conveniently releasing and adjusting the angle, and further quickly clipping.
The joint module 26 further comprises a first position limiting member, which comprises a first position limiting hole 264 provided on the predetermined of the joint set 260, and a first position limiting pillar 262 provided on the corresponding position of the hinge 263. The size of the first position limiting hole 264 is used to limit the space of the first position limiting pillar 262 for limiting the up/down angle of the platform 24 within a general used or reasonable adjustment range, such that can prevent the platform 24 falling from the improper adjustment or the accidentally drop. And, the first position limiting pillar 262 can be presented as a screw.
The sleeve 28 is slipped over an end of the crooked shaft 29, which can be as an axis for being rotate to adjust the waving angle of the platform 24, and further, the slipped length of which can be used to adjust the distance between the platform 24 and the base 27. After finishing the adjustment, the opened end of the sleeve 28 can clip the crooked shaft 29 fixedly according to a clipping member 281. The clipping member 281 can be selected to be as a quick release clipper for conveniently releasing and adjusting the angle and distance, and further quickly clipping.
Besides, a second position limiting hole 285 (referring to FIG. 3B) is provided on the predetermined position of the sleeve 28, and a second position limiting pillar 286 is provided on the corresponding position of the crooked shaft 29, such that is as a second position limiting member. The second position limiting member is also with the same function of limiting the space of the first position limiting pillar 286 for limiting the waving angle of the platform 24 and the position adjustment range according to he size of the second position limiting hole 285, such that can prevent the platform 24 falling or the sleeve 28 accidentally dropping. And, the second position limiting pillar 286 can be presented as a screw.
The lock module 21 used to link up the bracket 22 and the platform 24 comprises various types. Referring to FIG. 3A, is as an operation view of a preferred embodiment of the present invention according to FIG. 2. When the spiral rod 265 is loosened, the hinge 263 is movable, therefore, the hinge 263 cab be rotated with the bracket 22 and the platform 24 following for adjusting the up/down angle of the platform 24, or providing the adaptable storage angle for the support 20.
Referring to FIG. 3B and FIG. 3C, are respectively as other operation views of a preferred embodiment of the present invention according to FIG. 2. When the lock spiral rod 211 is loosened, the position of the platform 24 can be adjusted by user, as shown on FIG. 3B, or the angle of which can be adjusted, as shown on FIG. 3C, therefore, the platform 24 can be rotated and shifted, and after finishing the position adjustment, the lock spiral rod 211 has to be fastened. By the way, once the clipping member 281 is released, the sleeve 28 can be shifted in front or rear direction for adjusting the position of the platform 24.
Referring to FIG. 3D, regarding to adjust the waving angle of the platform 24, the clipping member 281 should be to released, the sleeve 28 can be rotated with the platform 24 along the axis (a1) of the crooked shaft 29, and after finishing the angle adjustment, the clipping member 281 has to be clipped, such that can improve the adaptability with respect to the operation of the support 20. During adjusting, the second position limiting hole 285 of the second position limiting member (referring to FIG. 3B) can be used to limit the space of the second position limiting pillar 286 in a reasonable range, such that can prevent the sleeve 28 accidentally dropping from taking off the crooked shaft 29, or prevent the platform 24 turned upside down due to the lager waving.
The crooked shaft 29 can be rotated by user along the axis (a2) of the base 27 for adjusting the position of the support 20 since the crooked shaft 29 and the base 27 are slipped. And the slipped section of which can be locked by a fixer 25 and the crooked shaft 29 for enhancing the linked of the crooked shaft 29 and the base 27.
Finally, referring to FIG. 3E, is a three-dimensional view of another preferred embodiment of the present invention. An end of the crooked shaft 29 can be pierced through the base 27 with the predetermined length to be as a plug rod 291 for being set with respect to other devices. For example, a screen 251 can be set on the plug rod 291, such that the support 20 can be used to support the keyboard and the screen 251 with following, thus, more convenient operation will be provided for users. Of course, according to the plugging of the screen 251 and the plug rod 291, the screen 251 can be rotated along the axis (a3) of the plug rod 291 for adjusting the direction of that, as well as, more convenient operation is provided for users.
The foregoing description is merely one embodiment of present invention and not considered as restrictive. All equivalent variations and modifications in process, method, feature, and spirit in accordance with the appended claims may be made without in any way from the scope of the invention.
