Description:
FIELD OF THE INVENTION  
       [0001]     The present invention relates to a stand assembly, more particularly to a stand assembly that comes with an adjustable carrier stand for holding an electronic device and allows users to adjust the position of the stand to facilitate the access and operation of the electronic device.  
       BACKGROUND OF THE INVENTION  
       [0002]     Unlike the past, the present world has entered into a new era with blooming developments of science and technology, and various precision electronic products bring us tremendous convenience and improve our living quality, and thus the quality of these electronic products is indispensable with our life. For instance, a handheld electronic device such as a personal digital assistant (PDA) or a mobile phone not only features a small size and a light weight but also integrates the functions of notebook, calendar, database, game, telephone directory, English-Chinese dictionary, drawing and calculator, etc. Therefore, more and more people have high demand for this type of handheld electronic devices in recent years, and thus manufacturers and companies spare no effort to continuously research and develop this type of electronic devices and provide powerful functions for users in addition to making these electronic devices lighter, thinner, and smaller.  
         [0003]     Regardless of these handheld electronic devices being used as an information management tool, a game machine, a music player, or a navigation system, a user may want to install these handheld electronic devices in a motor vehicle to facilitate the use of these handheld electronic devices while driving a motor vehicle. A traditional automobile stand can be used to achieve the foregoing objective.  
         [0004]     Please refer to  FIG. 1  for a traditional automobile stand  10  which comprises a bendable extended tube  11  having a frame  14  at one end and an attached section  12  at the other end; an electronic device  15  being installed on a side of the frame with its back facing the extended tube  11 , so that the electronic device  15  can be mounted onto the automobile stand  10 ; a sucking disc  13  being disposed on the attached section  12  at the end away from the extended tube  11  for attaching the automobile stand  10  onto a flat surface (such as the control panel) inside a motor vehicle, so that a user in the motor vehicle can adjust the extended tube  11  to set the electronic device  15  to an appropriate position.  
         [0005]     Although the design of the foregoing extended tube allows users to adjust and fix the electronic device in an appropriate using position, the extended tube will be deformed because the extended tube itself will become inflexible after being used for a while or due to the vibration produced by the moving motor vehicle, and thus the electronic device will come off easily from its original position. A user has to readjust the extended tube, which causes tremendous inconvenience when the user uses the electronic device. Therefore, designing a stand assembly for mounting an electronic device in a motor vehicle without the need of frequently adjusting the position of the electronic device demands immediate attention and improvement.  
       SUMMARY OF THE INVENTION  
       [0006]     In view of the shortcomings of the traditional automobile stand, the inventor of the present invention based on years of experience in the related industry to conduct extensive researches and experiments to overcome the shortcomings of the prior art and finally invented a stand assembly in accordance with the present invention in hope of contributing the innovative idea and design to the general public.  
         [0007]     The primary objective of the present invention is to provide a stand assembly comprising: a base, having an attached section on one side and a first prop stand on another side, and another end of the first prop stand is pivotally coupled to a second prop stand, and a pivotal axle disposed between the second prop stand and the first prop stand is connected perpendicularly to a central axle perpendicular to the base, another end of the second prop stand is pivotally coupled to a rotary stand, and a pivotal axle disposed between the rotary sand and the second prop stand is connected perpendicularly to a central axle disposed between the second prop stand and the first prop stand; a carrier stand being pivotally coupled to another end of the rotary stand, and a pivotal axle disposed between the carrier stand and the rotary stand is connected perpendicularly to a central axle disposed between the rotary stand and the second prop stand; and an electronic device disposed on another end of the carrier stand, such that when the stand is fixed onto a flat surface by the attached section, a user can turn the carrier stand, the rotary stand and the second prop stand to adjust the carrier stand to an appropriate position and angle to facilitate operating or accessing the electronic device.  
         [0008]     The above and other objects, features and advantages of the present invention will become apparent from the following detailed description taken with the accompanying drawings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0013]     Please refer to  FIG. 2  for a stand assembly according to a preferred embodiment of the present invention, which comprises a base  21 , an attached section  4  disposed on a surface of the base  21  for being attached and fixed onto a flat surface (such as a control panel in a motor vehicle), and a first prop stand  22  being disposed on another surface of the first prop stand  22  and a second prop stand  23  being pivotally coupled to another end of the first prop stand  22 , and a pivotal axle  31  disposed between the second prop stand  23  and the first prop stand  22  is connected perpendicularly to a central axle perpendicular to the base  21 , such that the second prop stand  23  can be rotated on the first prop stand  22 ; a rotary stand  24  being pivotally coupled to another end of the second prop stand  23 , and a pivotal axle  32  disposed between the rotary stand  24  and the second prop stand  23  is connected perpendicularly to a pivotal axle  31  disposed between the second prop stand  23  and the first prop stand  22 , such that the rotary stand  24  can be rotated on the second prop stand  23 ; and a carrier stand  25  being pivotally coupled to another end of the rotary stand  24 , and a pivotal axle  33  disposed between the carrier stand  25  and the rotary stand  24  (as shown in  FIG. 3 ) is connected perpendicularly to a pivotal axle  32  disposed between the rotary stand  24  and the second prop stand  23 , such that the carrier stand  25  can be rotated on the rotary stand  24 .  
         [0014]     Please refer to  FIG. 2  again. Since an electronic device (which is a handheld electronic device  15  such as a mobile phone or a personal digital assistant as shown in  FIG. 1  is installed, a user can turn the carrier stand  25 , the rotary stand  24  and the second prop stand  23  to adjust the carrier stand  25  into an appropriate direction to facilitate the operation and access of the electronic device when the stand  2  is mounted onto a flat surface by the attached section  4 .  
         [0015]     Please refer to  FIG. 4  for another preferred embodiment of the present invention. After the second prop stand  23  and the first prop stand  22  according to the aforementioned embodiment are separated, at least one extended stand  26  is pivotally connected onto the first prop stand  22 , and a pivotal axle  34  disposed between the extended stand  26  and the first prop stand  22  is connected perpendicularly to a central axle of the base, such that the extended stand  26  can be rotated on the first prop stand  22 . Another end of the extended stand is pivotally coupled to the second prop stand  23 , and a pivotal axle  36  disposed between the extended stand  26  and the second prop stand  23  is kept parallel with a pivotal axle  34  disposed between the extended stand  26  and the first prop stand  22 , such that the second prop stand  23  can be rotated on the extended stand  26 . Therefore, the second prop stand  23 , rotary stand  24  and carrier stand  25  are maintained at a specific distance away from (or proximate to) the base  21  by the structure and design of the extended stand  26 .  
         [0016]     Please refer to  FIGS. 2, 3  and  4  for each of the foregoing embodiment. The pivotal axles  31 ,  32 ,  33 ,  34 ,  36  comprises at least one elastic clip  35  for being clipped between each pivotal axle  31 ,  32 ,  33 ,  34 ,  36  and their corresponding base  21 , second stand  23 , rotary stand  24 , carrier stand  25  and extended stand  26  after the pivotal axles  31 ,  32 ,  33 ,  34 ,  36  are connected respectively to the corresponding base  21 , second stand  23 , rotary stand  24 , carrier stand  25  and extended stand  26 . Therefore, when the stand  2  is not turned, the structural design of the clip  35  makes the pivotal axles  31 ,  32 ,  33 ,  34 ,  36  to be engaged precisely with the corresponding base  21 , second stand  23 , rotary stand  24 , carrier stand  25  and extended stand  26 , such that the stand cannot be moved and turned freely.  
         [0017]     Please refer to  FIGS. 2, 3  and  4  again. When a user wants to turn the stand  2 , the elasticity of the clip  35  makes the clip  35  to produce a deformation at the turned portion as to release the each turned pivotal axle  31 ,  32 ,  33 ,  34 ,  36  from the corresponding base  21 , second prop stand  23 , rotary stand  24 , carrier stand and extended stand  26 , such that the stand  2  can be turned.  
         [0018]     Please refer to  FIG. 3 . The attached section  4  for each embodiment as shown in  FIG. 2  is a sucking disc  41 , and an insert member  42  is disposed at the center of the sucking disc  41 , and a through hole  43  is disposed at one end of the insert member  42  corresponding to the sucking disc  41 , and an accommodating section  44  of the insert member  42  is disposed on one side of the base  21  facing the attached section  4 ; and the accommodating section  44  is extended to a specific length in the direction away from the attached section  4  for accommodating the insert member  42 , and a sliding groove  45  corresponding to the through hole  43  is disposed on both sides of the accommodating section  44 , such that when the insert member  42  enters the accommodating section  44  to allow the sucking disc  41  to be placed adjacent to the base, both ends of the through hole  43  correspond to both sliding grooves  45  at the end away from the sucking disc  41 .  
         [0019]     Further, please refer to  FIG. 3  for the present invention again. The attached section  4  further comprises a turning section  46  having one end to be gripped by a user, and both sides of the other end having a latch plate  461 , and the external periphery of the accommodating section  44  can be accommodated precisely between the two latch plates  461 . A latch hole  462  corresponding to each of the two sliding grooves  45  is disposed on each of the two corresponding surfaces of the two latch plates  461  respectively, so that if the accommodating section  44  is accommodated between the two latch plates  461  and there is an insert member  42  accommodated in the accommodating section  44 , the two latch holes correspond to the two sliding grooves  45  respectively, and the two corresponding ends of the through hole  43  allow a positioning axle  47  to be extended into each latch hole  462 , sliding groove  45  and through hole  43  in sequence as to couple the sucking disc  41 , the base  21  and the turning section  46 .  
         [0020]     Please refer to  FIG. 3 . Since the external periphery of the sucking disc  41  is larger than the external periphery of the base  21  and the central position of the base  21  is protruded towards the first prop stand  22 , therefore the turning section  46  is turned towards one side to drive the positioning axle  47  away from the sucking disc  41  to produce a displacement in the sliding groove  45  while driving the insert member  42  to displace in the accommodating section  44 , and the external periphery of the sucking disc  41  is engaged with the external periphery of the base  21 , and a portion at the center of the sucking disc  41  produces a deformation along that direction. Therefore, when the base  21  is placed on a flat surface and the sucking disc  41  is in contact with the flat surface, the turning section  46  is turned to produce an attraction force between the sucking disc  41  and the flat surface as to attach the base  21  onto the flat surface.  
         [0021]     While the invention 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 invention set forth in the claims.
