Description:
FIELD OF THE INVENTION  
         [0001]    This invention relates to an apparatus, disposed in a housing of a computer, for use in disassembling peripheral devices from a computer by one touch operation, and especially to a port replicator for being disassembled from a notebook PC by one touch operation.  
         BACKGROUND OF THE INVENTION  
         [0002]    A design for optionally changing the components of an apparatus by the user&#39;s individual opinion can increase the use scopes and the varieties of the functions of the apparatus effectively. They are popular designs such as changing the geometrical structures of a mobile latch and achieving the effects of releasing and ejecting by a spring. The designs had been applied in different fields, such as the fabricated toys, fabricated models, and the peripherals of computers. Because some components of the apparatus may be heavy, it&#39;s a focal point to provide a design with enough support abilities and easy-separated structures.  
           [0003]    Nowadays, in the design field about a notebook PC, for improving the portability ability and simplifying the structure of the notebook PC, the varieties and numbers of the connecting ports are not as great as a traditional desktop computer. Besides, the universal serial bus had gradually displaced the traditional parallel ports and serial ports in the connecting ports of a notebook PC. However, the connecting ports of the traditional peripherals of computers such as the monitors, printers, modems, scanners, and joysticks may be still parallel ports or serial ports. Therefore, a port replicator is used for connecting a notebook PC to the traditional peripherals. An ideal port replicator not only provides greater expanded abilities and expanded selectiveness for a notebook PC but also simplifies the procedures of rearrangements of the peripherals.  
           [0004]    In general, a notebook PC usually possesses a “docking” for connecting to an external port replicator. The capabilities of a notebook PC will be as great as a desktop computer while connecting to a port replicator. A number of strength appears in the connection between the docking and the port replicator. Because of the self-weight of a notebook PC and the strength of the connection, a port replicator usually has particular designs for supporting and stabilizing while disassembling. However, designs simultaneously own the abilities of supporting, stabilizing, releasing, and ejecting are still deficient. In general, the mechanisms for releasing and ejecting are controlled by different operative devices, such as keys. Once the operative devices can&#39;t be worked simultaneously or are operated imbalanced, it would be difficult to disassemble the notebook PC from the port replicator even cannot be disassembled. In addition, the mechanisms for releasing and ejecting are always achieved by springs. The elasticity of a spring decays as time goes, so that it is possible that the notebook PC will not be released and rejected from the port replicator.  
           [0005]    Because of the technical defects described above, the applicant keeps on carving unflaggingly to develop “ONE-TOUCH RELEASE APPARATUS” through wholehearted experience and research.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0035]    Please refer to FIG. 1 showing the appearance of the port replicator of the present invention. As shown in FIG. 1, a port replicator PR includes a base  1 , a removable cover  2 , two conducting terminals  8 , two ejecting pins  51 , two latch ends  611 , and the key  43 . Wherein the conducting terminal  8 , the ejecting pin  51 , and the latch end  611  are protruded from the removable cover  2 , and the key  43  is located at one side of the port replicator PR.  
         [0036]    Please refer to FIG. 2 showing a side view of the connection between a notebook PC and a port replicator. As shown in FIG. 2, the ejecting pin  51  will be pressed down by the weight of the notebook PC  3  while the notebook PC  3  is located on the removable cover  2 . Without limit from ejecting pin  51 , the latch end  611  will be combined to a latch notch  31  of the notebook PC  3  via a wheel  65 , and the notebook PC  3  is be stabilized by the port replicator PR. On the other hand, the ejecting pin  51  will be blocked by the latch end  611  of the mobile latch  61  and cannot be back to the original state before being pushed.  
         [0037]    Please refer to FIG. 3 showing a structural diagram of the reciprocating device according to a preferred embodiment of the present invention. As shown in FIG. 3, a reciprocating device  4  includes a reciprocating plate  41  and a reciprocating base  42 , which is fixed on the reciprocating plate  41  and includes two symmetrical portions. Each of the symmetrical portions has the same moving structures, which include a track  421 , a roller notch  422 , a first incline  423 , a first reciprocating plane  424 , a second incline  425 , and a second reciprocating plane  426 . The roller notch  422  is composed of a first push plane  4221 , a second push plane  4222 , and a holding plane  4223 .  
         [0038]    Please refer to FIG. 4 showing the structural diagram of the stabilizing device according to a preferred embodiment of the present invention. As shown in FIG. 4, the stabilizing device  6  includes a mobile latch  61 , a stabilizing base  62 , a rigid cover  63 , and a latch spring  64 . Two ends of the mobile latch  61  are the latch end  611  and the stabilizing end  612  respectively. The stabilizing base  62  further includes a beam  621  with a hole  6211 , wherein the hole  6211  can be passed through by the ejecting pin  51  (as show in FIG. 1). The cover  63  needs to be fixed on the stabilizing base  62  for ensuring the mobile latch  61  working normally. In addition, a roller  7  is located into the inclined roller track  622 , and the stabilizing end  612  of the mobile latch  62  is located between the latch spring  64  and the roller  7 .  
         [0039]    Please refer to FIG. 5 showing a structural diagram of the prop device according to a preferred embodiment of the present invention. As shown in FIG. 5, a prop device  5  is composed of an ejecting pin  51 , two ejecting springs  52 , and a latch holder  511 .  
         [0040]    Please refer to FIG. 6. FIG. 6 shows the assembly of the reciprocating device, the prop device, the stabilizing device, and the base according to a preferred embodiment of the present invention.  
         [0041]    Please refer to FIG. 7. FIG. 7 shows a combination diagram of the reciprocating device, the prop device, the stabilizing device, and the base according to a preferred embodiment of the present invention.  
         [0042]    As shown in FIGS. 6 and 7, the stabilizing base  62  needs to be fixed on the reciprocating plate  41  first. Before the stabilizing base  62  being fixed, it needs to be sure that the roller  7  is located into the roller notch  422  of the reciprocating base  42 , the beam  621  needs to be stretched over the track  421 , and the hole  6211  can be passed through by the ejecting pin  51 . Because the latch end  611  will be blocked by the latch holder  511 , the action of the mobile latch  61  will be controlled by the latch holder  511  of the ejecting pin  51 . The protruding pillars  12  are fixed on the base  1  for supporting the removable cover  2  (As shown in FIG. 1), and the protruding lumps  11  are fixed on the base  1  for maintaining the moving scopes of the reciprocating plate  41 .  
         [0043]    Please refer to FIGS. 1, 4,  5 , and  6 . The port replicator PR indeed includes a pair of prop devices  5  and a pair of stabilizing devices  6 . Because the mechanisms of the two prop devices  5  or the mechanisms of the stabilizing devices  6  are all the same, that the following descriptions of the action mechanisms about the prop device  5  and stabilizing device  6  are merely dependent on one device of each pair, respectively. Please refer to FIG. 7. During a releasing procedure, the key  43  will be pushed for sequentially forming two stage key displacements, the first key displacement and the second key displacement, by a two-stage force. By the time, two correspondingly reciprocating base displacements, the first reciprocating base displacement and the second reciprocating base displacement, of the reciprocating plate  41  and the reciprocating base  42  fixed on the reciprocating plate  41  will be formed in relation with the first key displacement and the second key displacement respectively.  
         [0044]    Please refer to FIG. 6. Because of the push of the first push plane  4221 , the roller  7  will be moved in the inclined roller tracks  622  (shown in FIG. 4) and a first roller displacement is formed. During the procedure of the first roller displacement, the mobile latch  61  will be moved from the latch notch  31  (shown in FIG. 2) while the stabilizing end  612  (shown in FIG. 4) being pushed by the roller  7 . Because the mobile latch  61  is moved from the latch notch  31 , the notebook PC is released.  
         [0045]    Please refer to FIG. 2. Because the mobile latch  61  is moved during the first roller displacement, the ejecting pin  51  will not be limited by the mobile latch  61 . Then, the ejecting pin  51  will be pushed upward by the elasticity of the ejecting spring  52 .  
         [0046]    Please refer to FIG. 7. During the second reciprocating base displacement, the ejecting pin  51  will be moved onto the second reciprocating plane  426  via the second incline  425 . By the time, the notebook PC  3  will gradually be moved upward by the support force provided by the second incline  425  and the second reciprocating plane  426  (as shown in FIGS. 2 and 7). At the moment, an action controlled by one touch operation for releasing and ejecting a notebook PC is achieved. In general, the elasticity of the ejecting pin  52  will decay as time goes, and thus it is possible the elasticity provided by the ejecting pin  52  is not strong enough for ejecting the notebook PC  3 . Nowadays, the present invention provides a new design with the physical support from the second incline  425  and the second reciprocating plane  426  for overcoming the elasticity-fatigue failure.  
         [0047]    Please refer to FIGS. 3 and 6. The roller  7  will be pushed onto the first reciprocating plane  424  via the first incline  423  while being moved in the inclined roller track  622 , then the roller  7  won&#39;t be pushed by the first push plane  4221  during the second reciprocating base displacement.  
         [0048]    Please refer to FIG. 6. Once the two-stage force is removed, a rebound movement of the reciprocating plate  41  is formed by the elasticity of the reciprocating spring  44 . During the rebound movement, the ejecting pin  51  is moved back to the original position from the second reciprocating plane  426 , and the roller  7  is moved back to the roller notch  422 . Then, the roller  7  will be pushed back by the second push plane  4222 . In addition, the mobile latch  61  will be rebounded by the elasticity of the latch spring  64 . On the other hand, as the ejecting pin  52  is in an ejecting state, the moving scope of the mobile latch  61  will be restrained by the latch holder  511 . At the moment, the whole action of releasing and ejecting is finished.  
         [0049]    As above-mentioned, the present invention provides a release apparatus controlled by one touch operation. It solves kinds of problems appeared in the conventional fabrication procedure of components. For example, the problems of time-consuming and manpower-consuming caused by pushing all the controlling buttons simultaneously and equally will be solved easily by the present invention. Even more, the present invention provides a design with support force from inclines and planes for solving the problem of the elasticity fatigue of the spring as time goes. Things like that, effectively improving the defaults of the prior arts and being worthy for the industries are the purposes of the present invention.  
         [0050]    While the invention has been described in terms of what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention needs not be limited to the disclosed embodiment. On the contrary, it is intended to cover various modifications and similar arrangements included within the spirit and scope of the appended claims which are to be accorded with the broadest interpretation so as to encompass all such modifications and similar structures.
