Abstract:
A fixing seat includes a foundation bed and two clamping arms arranged on opposite sides of the bed, respectively. At least one of the clamping arms is movable transversely. A longitudinal slide channel is formed in each clamping arm to movably receive at least a protruding clamping portion that is movable along the slide channel, whereby the longitudinal and transverse distances between the clamping portions are both adjustable.

Description:
BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     The present invention relates to a fixing seat especially suitable for holding a small-size electronic product of various shapes and/or measurements decently.  
         [0003]     2. The Prior Arts  
         [0004]     To crop up as fast as the bamboo shoots after a spring rain, so many small-size electronic products, such as MP3 portable player, MP4 AV player, handy game player, cellular phone, and PDA, are presented to the market one after another. For easy holding in vehicle or another reason whatsoever, theoretically, an exclusive fixing seat made for a mating product, namely one for one, is preferred, however, for simplification, an average fixing seat is commonly configured such that an electronic product can be fixedly clamped by two clamping pieces having their width adjustable either by one single or two movable clamping wings. The clamping pieces of the fixing seat are such defective that they are immobile in longitudinal direction. It is all right for the clamping pieces to hold a cellular phone for example, because they are supposed to clamp at the phone on two sides in a middle portion; however, a lower half portion may be clamped this time in the case of a narrow long handy game player or other AV player that does not seem stable enough. Yet, a button disposed on a side surface of some electronic product for a special purpose may be triggered unexpectedly.  
       SUMMARY OF THE INVENTION  
       [0005]     The primary object of the present invention is to provide a fixing seat whose longitudinal clamping position is adjustable in addition to the adjustable transverse clamping position, so that an optimum clamping position is available for holding an electronic product of diversified shapes or different measurements.  
         [0006]     Another object of the present invention is to provide a fixing seat suitable to clamp more kinds of electronic product without causing impairments, in which the clamping position of clamping portions may be adjusted for clamping products of specific shapes; and it is possible to avert any accidental touch or damage to switches by adjusting the clamping portions in longitudinal direction.  
         [0007]     Yet, another object of the present invention is to provide a fixing seat with two rotatable stop blocks, which can be turned flat to enable the fixing seat to clamp an electronic product at its two sides of middle portion, and the foundation bed of the fixing seat may be turned from a usual longitudinal state into a transverse state to hence broaden the scope of usable products.  
         [0008]     In order to realize above objects, a clamping arm is arranged respectively on two corresponding sides of a foundation bed of the present invention, in which at least a clamping arm is movable transversely; a slide channel is provided to each clamping arm at an edge thereof longitudinally; at least a protruding clamping portion is formed slidable on the slide channel such that a user may change the clamping position in the longitudinal direction when necessary.  
         [0009]     For more detailed information regarding advantages or features of the present invention, at least one example of preferred embodiment will be described below with reference to the annexed drawings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0017]     As shown in  FIGS. 1 and 2 , a fixing seat of the present invention comprises a foundation bed  1  having a clamping arm  2 ,  3  disposed on each of two sides respectively. At least one clamping arm is movable transversely by means of a pushbutton  11  arranged on one side of the foundation bed  1  as well as the inside structure of the fixing seat such that the clamping arm(s) can be moved outwardly to change the distance between them for clamping an electronic product of different widths. In the present invention, since both the clamping arms  2 ,  3  are movable transversely, namely, a dual-side clamping way is taken as understood in a similar conventional interaction mechanism, hence it wouldn&#39;t be reiterated herein.  
         [0018]     Compared with a conventional fixing seat, each clamping arm  2 ,  3  is formed with a longitudinal slide channel  21 ,  31  having at least an upwardly protruded clamping portion, while there are two upwardly protruded clamping portions arranged on each clamping arm in this preferred embodiment, namely: the clamping portion  22 ,  23 ,  32 , and  33 . Every clamping portion can be moved longitudinally along the slide channel to which this clamping portion belongs in order to change the clamping position in the longitudinal direction so that a longer-size electronic product can be fastened stably, and an accidental touch to an ON/OFF switch or button can be thus averted effectively.  
         [0019]     As shown in  FIG. 3 , each pair of correspondent clamping portions  22 ,  23  or  32 ,  33  is arc-shaped, and is combined to form a semicircle. However, the shape of a clamping portion is not so limited, it may be formed in any shape whatever desired. Moreover, the surface of inner side of each clamping portion is attached with a shaped sponge  221 ,  231 ,  321 , and  331  for preventing a clamped object from being scratched. In addition, an inverted T-shaped check block  222 ,  322  is formed on the bottom end of each clamping portion  22 ,  32  (also, the same on the bottom end of the clamping portion  23 ,  33 ). To assemble, each check block is descended through a larger central opening  211 ,  311  then moved longitudinally and checked at the bottom end of a correspondent slide channel  21 ,  31  such that the check block is allowed to slide along the channel without departing from it.  
         [0020]     In this embodiment, two sides of the bottom edge of the foundation bed  1  are pivotally jointed with a rotatable stop block  5 , respectively, such that the stop blocks  5  are rotated upwardly to protrude over the top surface of the foundation bed  1  to prevent an electronic product held thereon from being slid down as shown in  FIG. 2 , or the stop blocks  5  may be rotated to lay horizontally as shown in  FIG. 1  for holding a long and narrow product. The detailed structure is shown in  FIG. 3 , where the bottom end of each stop block  5  is sheathed around a protruding pin  12  at the bottom edge of the foundation bed  1  through a spring  13 , and each stop block  5  is rotatably locked to the protruding pin  12  by means of a bolt  14 . Due to the interposed spring  13 , each the stop block  5  is fastened with a proper tension, so that it can be rotated and fixed then and there wherever desired.  
         [0021]      FIGS. 4 and 5  show another embodiment of the present invention for improving a stop block  6  at the bottom edge of the foundation bed  1 . In this embodiment, two stop blocks  6  are vertically disposed to protrude over the foundation bed  1 , and a support rod  61  arranged in the bottom end of the stop blocks can be plugged in the foundation bed  1  such that the stop blocks  6  can be moved outwardly a proper distance respectively according to requirements for holding an electronic product of different widths or specific shapes.  
         [0022]     An electronic product may be used in diversified forms. For example, it could be held vertically for normal use while transversely for viewing video images, or the length thereof may be far longer than the width. Referring to  FIG. 6 , a product  7  may be held by laying the stop blocks  5  flat, then, clamping the middle part of the product on two sides with the clamping portions  22 ,  23  of the clamping arm  2  and the clamping portion  32 ,  33  of the clamping arm  3 , and by so doing, it is possible to dodge some pushbuttons. If it is so required to handle the product transversely for appreciating video images, all a user has to do is turn the entire foundation bed to the direction where the clamping arm  2 ,  3  are located at a top and a bottom position, respectively, and of course, under this situation, the foundation bed  1  has to be fixed to a rotatable auxiliary sucker or any other auxiliary fixing supporter.  
         [0023]     In the above described, at least one preferred embodiment has been described in detail with reference to the drawings annexed, and it is apparent that numerous changes or modifications may be made without departing from the true spirit and scope thereof, as set forth in the claims below.
