     DESCRIPTION OF EMBODIMENTS 
       [0047]    A first embodiment of the present invention will be described with reference to  FIGS. 1 to 8 . 
         [0048]    A transforming block toy A of the first embodiment changes into a shape of an automobile after transformation, and includes a base portion  1 , a wheel operating unit  2  accommodated in the base portion  1 , and a control unit  3  and an undulating unit  4  of a slide body provided above the wheel operating unit  2 . 
         [0049]      FIGS. 1 to 4  illustrate a state before transformation in which the transforming block toy A is blocked. In this state, a trigger  11  is accommodated in a front plate  10   a,  wheels  19  are accommodated in a circular notch portion  10   c  of left and right side plates  10   b,  an engagement portion  42  of a top plate  40  is engaged with an engagement portion  11   d  of the trigger  11 . Therefore, although this structure is a rectangular parallelepiped which is accommodated inside the transforming block toy A and does not protrude to the surface, by turning on the trigger  11 , the respective constituent parts move in cooperation with each other and are transformed as illustrated in  FIGS. 6 to 8 . Hereinafter, the first embodiment will be described in detail. 
         [0050]    In the base body  10 , eight engagement recessed portions  15  are formed in the bottom plate  10   d,  and the engagement recessed portions  15  are engaged with the engagement protruding portions of another block toy. 
         [0051]    The trigger  11  is formed on the front plate  10   a  of the front part (the left part in  FIG. 1 ) of the base body  10 . The trigger  11  has a substantially rectangular shape including a lower pressing unit  11   a  and an upper operating unit  11   b,  a shaft  14  is inserted through a shaft hole  11   c  provided at the center and is pivotally attached to the base body  10  by the shaft  14 . 
         [0052]    A spring  12  is interposed between the pressing unit  11   a  and a spring supporting portion  10 s of the front part of the base body  10  to always bias the pressing unit  11   a  forward. Therefore, the engagement portion  11   d  of the tip of the operating unit  11   b  is biased so as to always pivot backward and maintains an engaged state with an engagement portion  42  of a top plate  40  to be described later. 
         [0053]    The wheel operating unit  2  is formed in a lower part of the base body  10 . 
         [0054]    The wheel operating unit  2  is constituted by connecting a wheel mounting base  20  and a lifting body  29  with a link  22  via the spring  21 . Axles  18  are inserted through the bearings  20   a  at the front and rear ends of the wheel mounting base  20  to mount the wheels  19 . 
         [0055]    The link  22  includes a bearing  22   a  at the center and has an engaging hole  22   b  and an engaging hole  22   c  provided on both sides thereof. 
         [0056]    Two recessed portions  20   b  for accommodating the bearings  22   a  of the links  22  are formed on the upper surface of the wheel mounting base  20 , and protrusions  20   c  are formed at four locations on both side surfaces of the front part of the recessed portions  20   b,  respectively. Similarly, two recessed portions  29   b  for accommodating the bearings  22   a  of the links  22  are formed on the lower surface of the lifting body  29 , and protrusions  29   c  are formed at four locations on the both side surfaces of the rear part of the recessed portions  29   b.    
         [0057]    When the wheel operating unit  2  is assembled, the wheel mounting base  20  and the lifting body  29  overlap each other with the spring  21  interposed therebetween, and the two links  22  are combined with the recessed portion  20   b  of the wheel mounting base  20  and the recessed portion  29   b  of the lifting body  29  and are pinched therebetween. 
         [0058]    Further, the front engaging hole  22   b  of the link  22  is fitted to the protrusion  20   c  of the wheel mounting base  20 , and at the same time, the rear engaging hole  22   c  is fitted to the protrusion  29   c  of the lifting body  29 . Thereafter, the shafts  23  and  23  are inserted through the bearings  22   a  and  22   a  of the links  22  and  22  and are fixed to the base body  10 . 
         [0059]    The control unit  3  of the slide body is formed above the wheel operating unit  2 . 
         [0060]    The control unit  3  of the slide body includes an operation plate  30 , and an engaging member  44  engaged with a recessed portion  39  formed on the front part of the operation plate  30 . 
         [0061]    The engaging member  44  includes a seat plate  44   b  accommodated in the recessed portion  39 , and two pins  44   a  fixed to the seat plate  44   b.    
         [0062]    The pins  44   a  are movably mounted to two elongated holes  41   b  provided on the top plate  40 , and the upper ends of the pins  44   a  are fixed to mounting units  46  and  46  provided on the bottom portion of the slide body  45 . 
         [0063]    The spring  31  is interposed to the bearing  29   a  at the rear part of the lifting body  29  of the wheel operating unit  2 , and the shaft  32  is mounted to the inner side of the operation plate  30  through the bearing  30   a  of the operation plate  30 . By fixing the shaft  32  to the rear part of the base body  10 , the operation plate  30  is biased so as to always rotate upward about the shaft  32  by the resilient force of the spring  31 . 
         [0064]    The undulating unit  4  is formed above the control unit  3  of the slide body. 
         [0065]    The undulating unit  4  includes a top plate  40 , a slide body  45  and the like. 
         [0066]    A recessed portion  41  for accommodating the slide body  45  is formed on the upper surface of the top plate  40 , two rails  41   a  for causing the slide body  45  to slide are formed on the surface of the recessed portion  41 , and two elongated holes  41   b  for causing the pin  44   a  to penetrate and move along the slide body  45  are provided. 
         [0067]    The slide body  45  is stopped in a state of being always biased forward by the spring  43  in the recessed portion  41 . 
         [0068]    The rear end of the top plate  40  is pivotally supported on the base body  10  by inserting the shaft  34  into the bearing  40   a  via the spring  33  and by inserting the shaft  34  into the bearing  10   e  of the base body  10  at the same time, and the rear end of the top plate  40  is biased to always pivot upward about the shaft  34  by the spring  33 . 
         [0069]    The operation of the first embodiment configured as described above will be described. 
         [0070]    Although the upward rotational force is imparted to the top plate  40  by the spring  33 , since the engagement portion  42  at the tip is engaged with the engagement portion  11   d  of the trigger  11  in the block state, the pivoting of the top plate  40  is restricted. 
         [0071]    When the pressing unit  11   a  of the trigger  11  is pushed inward (to the right side in  FIG. 4 ), the operating unit  11   b  pivots outward to release the engaged state between the engagement portion  11   d  and the engagement portion  42  of the top plate  40 . Along with this, the top plate  40  pivots upward about the shaft  34  by the resilient force of the spring  33 . 
         [0072]    Along with this, since the upper end of the engaging member  44  is fixed to the mounting unit  46  of the bottom portion of the slide body  45 , the engaging member  44  rises together with the top plate  40  and is disengaged from the recessed portion  39  of the operation plate  30 , and at the same time, the engaging member  44  moves forward together with the slide body  45  by resilient force of the spring  43 . 
         [0073]    Simultaneously with the upward pivoting of the top plate  40 , the operation plate  30  pivots upward about the shaft  32  by the resilient force of the spring  31 . Accordingly, the lifting body  29  moves forward and upward by the resilient force of the spring  21  and the operation of the link  22 . 
         [0074]    Since the link  22  pivots about the shaft  23  at the same time, the wheel mounting base  20  and the wheel  19  move downward. A state in which the transforming block toy A is transformed into an automobile in this way is illustrated in  FIGS. 6 to 8 . 
         [0075]    The effect of the present embodiment which operates as described above is that, since the engaged state of each internal mechanism is released only by pushing the trigger  11 , each part moves, undulates, or slides by the force of the spring and the block itself is transformed, and since the block is transformed into a completely new shape such as an automobile which cannot be imagined from the block state, there is an interest that the block changes into an unexpected shape. 
         [0076]    Further, since the transforming block toy can be played by engaging with another block as a normal block in a non-transformed state, and can be played as an automobile toy after transformation, it is possible to enjoy a single block many times. 
         [0077]    A second embodiment of the present invention will be described with reference to  FIGS. 9 to 16 . 
         [0078]    A transforming block toy B of the second embodiment changes into the shape of elephant of an animal after transformation, and includes a cover member  90 , a base portion  5  accommodated in the cover member  90 , a leg operating unit  6  formed in the lower part, and a nose operating unit  7  and an ear operating unit  8  which are formed in the front part. 
         [0079]      FIGS. 9 to 11  illustrate a state before transformation in which the transforming block toy B is blocked. In this state, the leg operating unit  6  is accommodated in the lower part of the base body  50 , the nose operating unit  7  is accommodated in the front part (left part in  FIG. 11 ) of the cover member  90 , the ear operating unit  8  is accommodated in the front part of the cover member  90 , and the trigger  56  is accommodated in the rear plate  90   c.    
         [0080]    Therefore, although the internal structure is a rectangular parallelepiped that is accommodated in the transforming block toy B and does not protrude to the surface, by turning on the trigger  56 , the respective constituent parts move in cooperation with each other and are transformed as illustrated in  FIGS. 13 to 16 . Hereinafter, the second embodiment will be described in detail. 
         [0081]    Eight engagement recessed portions  53  are formed in the bottom plate  50   d  of the base body  50 , and the engagement recessed portions  53  are engaged with engagement protruding portions of another transforming block toy.

         [0083]    On the inside of the base body  50 , a leg operating unit  6  including a leg connecting unit  60  and leg mounting units  61  and  61  are formed. The shaft  65  is inserted through the shaft hole  61   a  of the tip and the shaft hole  60   b  of the leg connecting unit  60 , and the leg mounting unit  61  is pivotally mounted to the leg connecting unit  60 . 
         [0084]    On the other hand, the leg mounting unit  61  is pivotally mounted to the base body  50  by inserting the shaft  66  into the bearing  61   b  of the tip. Reference numeral  54  denotes a pin which fixes the base body  50  and the cover member  90 . 
         [0085]    A nose operating unit  7  is provided in the front part of the base body  50 . 
         [0086]    The nose operating unit  7  represents a nose of an elephant, and includes a case  71  which is bent downward and has a hollow inside, a spring support rod  73  accommodated inside the case  71 , and a spring  72  wound around the spring support rod  73 . 
         [0087]    As illustrated in the drawings, in the block state, the case  71  of the nose operating unit  7  is placed on the slope  50   a  at the front end of the base body  50 , and the engagement portion  73   a  of the upper end of the spring support rod  73  is fixed to the upper end of the cover member  90 . 
         [0088]    At the same time, an upper end protrusion  71   a  of the case  71  is engaged with the engaging protrusion  60   a  of the tip of the leg connecting unit  60  to lock the case  71  inside the base body  50  against the resilient force of the spring  72 . 
         [0089]    A pair of ear operating units  8  is provided on both sides of the front end of the cover member  90 . 
         [0090]    The ear operating unit  8  includes ear portions  80  representing elephant&#39;s ears, and a spring  82  and a shaft  83  for pivotally mounting the ear portions  80  to the cover member  90 . 
         [0091]    The bearing  80   a  is formed on the inner side of the front end of the ear portion  80 , the engaging member  81  horizontally extends to the inner side of the ear portion  80 , and an engaging claw  81   a  facing downward is formed at the tip of the engaging member  81 .

         [0092]    The operation of the transforming block toy B configured as described above will be described. 
         [0093]    When the rear trigger  56  is pivoted upward about the shaft  59  from the block state of  FIGS. 9 to 11 , an abutting portion  60   c  of the leg mounting unit  60  on which the tip engaging claw  57  abuts is pushed downward. As a result, the leg connecting unit  60  moves backward and downward, while pivoting about the shaft  65 . 
         [0094]    Along with the backward movement of the leg connecting unit  60 , the leg portion  62  pivots downward about the shaft  66  and protrudes from the hole  53  of the bottom plate  50   d.    
         [0095]    Also, by the backward movement of the leg connecting unit  60 , the engagement between the upper end  71   a  of the case of the nose operating unit  7  and the engaging protrusion  60   a  of the tip of the leg connecting unit  60  is disengaged, and the case  71  moves downward by the resilient force of the spring  72 . 
         [0096]    Along with this, the engagement between the engaging claw  81   a  of the ear operating unit  8  and the engagement portion  61   c  of the leg mounting unit  61  is disengaged, and the ear portion  80  pivots outward by the resilient force of the spring  82 . In this way, the transforming block toy B enters the state illustrated in  FIGS. 13  to  16 . 
         [0097]    The effect of the present embodiment is that, since the engaged state of each internal mechanism is released only by pulling the trigger  56 , each part moves, slides or opens by the force of the spring, and the block main body is transformed into a shape that cannot be imagined at all such as animal which imitates an elephant, and thus, there is an interest that the block changes into an unexpected shape. Further, in a state in which the transforming block toy is not transformed, it is possible to play with the transforming block toy by engaging with other blocks as a normal block. 
         [0098]    A third embodiment of the present invention will be described with reference to  FIGS. 17 to 26 . 
         [0099]    A transforming block toy C of the third embodiment changes into the shape of an eagle of a bird after transformation and includes a base portion  100 , a body portion  120  provided on the base portion  100 , a head portion  140  and wing portions  160  and  160  provided on the body portion  120 . 
         [0100]    In the transforming block toy C, eight engagement protruding portions  200  are provided on the upper surface, and engagement recessed portions  201  are formed on the lower surface. 
         [0101]    As illustrated in  FIGS. 22, 24 , and the like, the base portion  100  is provided with a mounting unit  105  of the body erected on the rear portion of the base body  101 , and a bearing  106  of a shaft  119  formed on the upper portion of the mounting unit  105  of the body. 
         [0102]    Further, two triggers  102  imitating legs of an eagle protrude from both sides of the front part of the base body  101 . A gap  109  is formed between the two triggers  102 . The head portion  140  is accommodated in the gap  109  in a block state, and the protrusion  151  of the head portion  140  comes into contact with the base body  101  (see  FIG. 21 ). 
         [0103]    The body portion  120  includes a lower member  121  and an upper member  131 . 
         [0104]    The lower member  121  is provided with support bases  122  on both sides, and the support bases  122  are connected with a connection plate  123  to form an H shape, and a bearing plate  126  is erected on the front and rear parts of the support base  122 . The bearing plate  126  is provided with a bearing  127  through which a shaft  172  is inserted. 
         [0105]    The upper member  131  has four engagement protruding portions  200  formed on the upper plate  132 , and side plates  133  are provided on both sides of the upper plate  132 . Four bearing plates  137  protrude outward and are mounted to both sides of the front end and the rear end of the side plate  133 . The bearing plate  137  is provided with a bearing  138  through which the shaft  172  is inserted. 
         [0106]    The head portion  140  has a beak  144  formed at the tip of the head main body  141 , and the engagement portion  150  is accommodated in the inner part  143  of the head main body  141 . 
         [0107]    The engagement portion  150  includes a protrusion  151  at the tip, and a spring  153  wound around a support rod  152  provided inside. 
         [0108]    Reference numeral  142  denotes a bearing through which the shaft  129  is inserted with the spring  128  interposed therebetween, and the head portion  140  is pivotally supported inside the upper member  131  by the shaft  129 . 
         [0109]    The wing portion  160  includes left and right wing portions mounted to both sides of the body portion  120 , but since the shapes are objects, the same members are denoted by the same reference numerals. 
         [0110]    The wing portion  160  includes a mounting unit  161  to the body portion, and a tip portion  181  pivotally mounted to the mounting unit  161 . 
         [0111]    The mounting unit  161  is divided into two members, an engaging protrusion  200  is formed on the upper surface, a bearing  162  for being pivotally mounted to the body portion  120  is formed on one side, and a bearing  164  for being pivotally mounted to the tip portion  181  is formed on the other side. 
         [0112]    The mounting unit  161  is disposed inside the bearing plate  137 , and the shaft  172  is mounted by being inserted into the bearing  162  and the bearing  138  via the spring  171 . 
         [0113]    The tip portion  181  has a hollow inside to accommodate the engagement portion  183 , and a bearing  182  is provided at an end portion. The shaft  174  is inserted through the bearing  182  and the bearing  164  of the mounting unit  161  via the spring  173  and is pivotally mounted to the mounting unit  161 . 
         [0114]    The engagement portion  183  includes a protrusion  184  of the tip, and a spring  186  wound around a support rod  185  provided inside, and a covering body  187 . The protrusion  184  is in contact with and engaged with the recessed portion  104  provided on both side portions of the base body  101 . 
         [0115]    The operation of the transforming block toy C configured as described above will be described. 
         [0116]    When the front trigger  102  pivots downward about the shaft  119  from the block state of  FIGS. 17 to 21 , the protrusion  151  of the head portion  140  separates from the base body  101  and pivots upward by the resilient force of the spring  128 , and the body portion  120  undulates. 
         [0117]    At the same time, the mounting unit  161  is pivoted outward by the resilient force of the spring  171 , the engagement portion  183  is subsequently separated from the recessed portion  104  of the base body  101 , and the tip portion  181  is pivoted outward by the resilient force of the spring  173 , and the transforming block toy C enters the state of  FIGS. 23 to 26 . 
         [0118]    Further, the body portion  120  pivotally supported by the shaft  119  can be further manually undulated. 
         [0119]    The effect of the present embodiment is that, since the engaged state of each internal mechanism is released only by pulling the trigger  102  downward, each part moves, undulates or opens by the force of the spring, and since the block main body is transformed into a shape which cannot be imaged at all such as an animal imitating the eagle, there is an interest that the black changes into an unexpected shape. Further, in a state in which the transforming block toy is not transformed, it is possible to play with the transforming block toy by engaging with other blocks as a normal block.
