Abstract:
In order to provide a conjuring tool which prevents a viewer from recognizing the existence of a set thread and which is simple in construction and operation, there is proposed a conjuring tool comprising a case main body  20  having a single opening where a drawer  10  is accommodated and a thread  30  fixed at one end thereof to a single location either on the drawer  10  or on the case main body  20,  wherein the thread  30  is set so as to emerge from the inside of the case main body  20  to the outside thereof.

Description:
BACKGROUND OF THE INVENTION  
       [0001]     1. Technical Field  
         [0002]     The present invention relates to a box-like conjuring tool which can give a viewer not only a wonder that the conjuring tool moves and rises of itself on the hand of an operator but also a wonder that a drawer of the conjuring tool opens of itself for the viewer to find that some article exists in the drawer that was empty before.  
         [0003]     2. Description of the Related Art  
         [0004]     Conventionally, there have existed conjuring tricks that a matchbox moves and rises of itself on the hand by being manipulated with a thread.  
         [0005]     When a conjuring trick of this type is performed, firstly, as shown in  FIG. 14 ( a ), for example, an end of a thread is attached to an end portion of an outer box of a matchbox, and thereafter, a drawer is inserted in the outer box in this state together with the thread in a direction as indicated by an arrow in the drawing. Thus, the drawer is inserted into the outer box in such a manner that the thread ties around the drawing in a longitudinal direction, whereby a conjuring tool is assembled completely.  
         [0006]     Then, the thread is passed between the middle finger and the ring finger and the other end of the thread is fixed to a belt on a pair of trousers or a coat. As this occurs, as shown in  FIG. 14 ( b ), the thread extends towards the operator so as to pass through the interior of the outer box, is exposed vertically on part of the drawer facing the operator and then, extends away from the operator so as to pass through the interior of the outer box again in an opposite direction, whereby the thread is allowed to tie around the drawer in a longitudinal direction, the matchbox being then placed on the hand in this state.  
         [0007]     In a state in which the matchbox is set on the hand as has been described above, when the operator moves slowly the handforwards, since the matchbox is drawn forwards by the thread, the matchbox moves forwards on the hand. Then, when the matchbox moves near to a root position between the middle finger and the ring finger, the matchbox which is being drawn by the thread is caused to rise then on the hand, when continuing to be so drawn by the thread, the matchbox falls down on the hand, and when further continuing to be drawn by the thread, the drawer appears out of the outer box.  
         [0008]     Thus, a viewer can be given the wonder that the matchbox moves, rises and opens of itself.  
         [0009]     Note that the conventional conjuring tool that has been described above is disclosed in the following related-art document.  
         [0010]     Page 351 of “Encyclopedia of Impromputu Magic” written by Martin Gardner and published by Magic Inc. in 1978.  
         [0011]     However, when the matchbox is used in the conventional manner, since the thread passing between the middle finger and the ring finger is caused to exist on the viewer&#39;s side as shown in  FIG. 14 ( b ), there is caused an inconvenience that the thread is seen by the viewer.  
         [0012]     In addition, in the conventional conjuring trick using a matchbox, the matchbox only moves and opens, and no more wonder can be given to the viewer, and hence the conventional trick lacks the entertaining properties.  
       SUMMARY OF THE INVENTION  
       [0013]     Then, an object of the present invention is to provide a box-like conjuring tool which can give a viewer not only a wonder that the conjuring tool moves and rises of itself on the hand of an operator but also awonder that a drawer of the conjuring tool opens of itself for the viewer to find that some article exists in the drawer that was empty before, which can obviate a risk that a thread that is set accordingly is recognized by the viewer and which is simple in construction and operation.  
         [0014]     With a view to attaining the object, according to the present invention, there is provided a conjuring tool comprising a case main body having a single opening where a drawer is accommodated and a thread fixed at one end thereof to a single location either on the drawer or on the case main body, wherein the thread is set so as to emerge from the inside of the case main body to the outside thereof. According to this construction, since the opening where the thread is exposed in the conventional case is in a shielded state, the existence of the thread cannot be visualized by the viewer.  
         [0015]     In addition, in the conjuring tool constructed as described above, a rear wall of the drawer is constructed to slide upwardly, so that a gap is produced at a lower end of the rear wall by causing the rear wall to deviate upwardly, whereby one end of the thread may be fixedly held between the rear wall and a bottom surface of the drawer by lowering the rear wall that has so deviated upwardly with the one end of the thread being placed in the gap.  
         [0016]     Furthermore, in the conjuring tool constructed as described above, the drawer has a double drawer structure comprising an inner accommodating case for accommodating an article in advance and an outer drawer case for accommodating the inner accommodating case, so that the inner accommodating case can be slid to be drawn out from a rear of the outer drawer case, whereby when trying to draw the drawer case from the case main body, either an operation in which only the outer drawer case is drawn out of the case main body or an operation in which the outer drawer case is drawn out of the case main body together with the inner accommodating case which is being accommodated in the outer drawer case may be performed by an operation from a location outside the case main body.  
         [0017]     Moreover, in the conjuring tool constructed as described above, a rear wall of the drawer is constructed to slide upwardly, so that a gap is produced at a lower end of the rear wall by causing the rear wall to deviate upwardly, whereby one end of the thread may be fixedly held between the rear wall and a bottom surface of the drawer by lowering the rear wall that has so deviated upwardly with the one end of the thread being placed in the gap.  
         [0018]     According to the conjuring tool of the present invention, a viewer can be given not only a wonder that the matchbox moves and rises of itself on the hand of the operator but also a wonder the drawer opens of itself to show that some article is contained in the drawer that should have been empty.  
         [0019]     In addition, since the thread can be removed from the conjuring tool easily, the operator can allow the viewer to verify the conjuring tool after the thread has been removed from the conjuring tool so as to let the viewer have an impression that there has been set no trick on the conjuring tool, thereby making it possible to give the viewer a wonder more. Moreover, since there is no risk at all that the set thread is looked at by the viewer and the construction and operation of the conjuring tool is simple, there can be provided an advantage that even a child who has no skilled technique can perfomr a conjuring trick easily using the conjuring tool according to the present invention.

     DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0034]     Hereinafter, a conjuring tool according to an embodiment of the present invention will be described by reference to the accompanying drawings.  
         [heading-0035]     [Construction of Conjuring Tool] 
         [0036]     Firstly, the construction of a conjuring tool  1  according to an embodiment of the present invention will be described by reference to FIGS.  1  to  6 . A conjuring tool  1  according to an embodiment of the present invention includes a case main body  20  having a single opening where a drawer  10  is accommodated and a thread  30  (in this embodiment, the thread is taken up around a thread take-up device  31 ). Note that in this embodiment, a side of the conjuring tool  1  where the drawer  10  opens (a side of the case main body where the opening is provided) is defined as a “front” and a side of the conjuring tool  1  where the drawer  10  abuts when accommodated in the case main body  20  (an opposite side of the case main body) is defined as a “rear”.  
         [0037]     As shown in  FIG. 2 , the drawer  10  is constructed so as to have a double drawer structure including a inner accommodating case  11  and an outer drawer case  12  which accommodates the inner accommodating case  11 , whereby the inner accommodating case  11  is slid to be drawn from a rear of the outer drawer case  12 . In addition, a rear wall  13  of the inner accommodating case  11  is constructed so as to slide upwardly as shown in  FIG. 3  to thereby produce an opening there below. Furthermore, a bottom opening  14  is provided in a bottom surface of the outer drawer case  12  at a rear end thereof for allowing a projection  21  on the case main body  20  to be inserted there into as will be described later on, and furthermore, a stepped wall portion  15  is provided at a lower portion of the inner accommodating case  11  at a rear end thereof for engagement with the projection  21  on the case main body  20  as shown in  FIG. 4 . Note that this stepped wall portion  15  is set to a size which avoids a protrusion from a lower surface of the outer drawer case  12  when the inner accommodating case  11  is accommodated in the outer drawer case  12 .  
         [0038]     As shown in  FIG. 5 , the case main body  20  is constructed so as to be press deflected at a rear end on the bottom side thereof inwardly of the case main body  20  when a force is applied thereto in a direction indicated by an arrow in the drawing. In addition, the projection  21  is provided on an inner surface of the bottom side at the rear end of the case main body  20  so as to be inserted into the bottom opening  14  on the drawer  10  when the operator pushes upwardly the rear end of the bottom side of the case main body  20 .  
         [0039]     According to the construction that has been described heretofore, when the operator opens the drawer  10  while pushing upwardly the rear end of the bottom side of the case main body  20 , since the projection  21  enters the bottom opening  14  on the drawer  10  so as to be brought into engagement with the stepped wall portion  15 , the inner accommodating case  11  is allowed to remain within the case main body  20  as shown in  FIG. 6 ( a ), and only the outer drawer case  12  can be drawn out of the case main body  20 . On the other hand, when the operator opens the drawer  10  without pushing upwardly the rear end of the bottom side of the case main body  20 , the outer drawer case  12  is allowed to be drawn out of the case main body  20  while accommodating therein the inner accommodating case  11  as shown in  FIG. 6 ( b ).  
         [0040]     In addition, while the color of the case main body  20  and the color of the thread  30  of the thread take-up device  31  need to be the same in order to make it difficult for the viewer to visualize the existence of the thread  30 , by determining to use black as the colors thereof, the existence of the thread  30  can be made difficult to be visualized by the viewer.  
         [heading-0041]     [Procedure for Operating Conjuring Tool] 
         [0042]     Next, referring to FIGS.  7  to  13 , an example of a procedure for performing a conjuring trick using the conjuring tool  1  that is constructed as has been described above.  
         [0043]     Firstly, before starting to perform a conjuring trick, as shown in  FIG. 7 , the operator causes the rear wall  13  of the inner accommodating case  11  of the drawer  10  to deviate upwardly to produce a gap at a lower end of the rear wall  13 , place a distal end of the thread  30  on the thread take-up device  31  and lowers the rear wall  13  so as to hold the thread  30  in the gap. In addition, as this occurs, an article (an accommodated article) such as a piece of paper on which a message is written or a bank note is accommodated in the inner accommodating case  11  in advance. Then, the inner accommodating case  11  which is holding the thread  30  and accommodating the article therein is accommodated in the outer drawer case  12 , and thereafter, the outer drawer case  12  is accommodated in the case main body  20  as is shown in  FIG. 8 . Thus, the thread  30  fixed at one end thereof to the rear wall  13  of the drawer  10  passes under the drawer  10  and emerges from the interior of the case main body  20 .  
         [0044]     Following this, as is shown in  FIG. 9 ( a ), the operator fixes the other end of the thread  30  by placing the thread take-up device  31  in the pair of trousers and the like and rests the case main body  20  on the hand in such a manner that the thread  30  extends, as shown in  FIG. 9 ( b ), from the back to the palm of the hand by passing between the middle finger and the ring finger. As this occurs, since the thread  30  passes on the back of the hand and the arm, there is no case where the thread  30  is visualized by the viewer.  
         [0045]     From the state described above, the operator firstly opens the drawer  10  as shown in  FIG. 10  while pushing upwardly the rear end of the bottom side of the case main body  20  with the finger of the hand through which the thread  30  passes and allows the viewer to verify the interior of the drawer  10 . As this occurs, according to the principle illustrated in  FIG. 6 ( a )., the inner accommodating case  11  in which an article has been placed in advance remains within the case main body  20 , and only the outer drawer case  12  is drawn out of the case main body  20 , whereby the viewer recognizes that the drawer  10  is empty.  
         [0046]     Next, the operator closes the drawer  10  (in reality, the outer drawer case  12 ) and pulls the thread  30  by extending the arm forward or moving the waist backward in a state where the case main body  20  is being placed on the hand as shown in  FIG. 9 ( b ). Then, the case main body  20  starts to move forward on the hand by virtue of the tension of the thread  30 , whereby the viewer feels a wonder that the case main body  20  has started to move of itself.  
         [0047]     Following this, as shown in  FIG. 11 ( a ), when the operator puts the case main body  20  at a more forward portion of the hand and pulls the thread  30  in a similar manner to that described above, the case main body  20  slowly rises on the hand as shown in  FIG. 11 ( b ) by virtue of the tension of the thread  30 , whereby the viewer feels a wonder that the case main body rises of itself.  
         [0048]     Furthermore, when the operator puts the case main body  20  on the hand in such a manner that the case main body  20  falls down towards the operator on the hand as shown in  FIG. 12 ( a ) and then pulls the thread  30  in the similar manner to that described above, the drawer  10  is opened by virtue of the tension of the thread  30  as shown in  FIG. 12 ( b ). As this occurs, since there is no force applied to the rear end of the bottom side of the case main body  20  which attempts to push upwardly the relevant location of the case main body  20 , due to the principle illustrated in  FIG. 6 ( b ), the outer drawer case  12  is drawn out of the case main body  20  in a state where the inner accommodating case  11  in which the article has already been placed is accommodated in the outer drawer case  12 , whereby the viewer feels at the same time not only a wonder that the drawer  10  opens of itself but also a wonder that the article appears all of sudden in the drawer  10  that has been confirmed empty before.  
         [0049]     Lastly, as shown in  FIG. 13 , the operator draws the drawer  10  from the case main body  20  completely, and asks the viewer to verify the case main body  20  and the drawer  10 . As this occurs, the end of the thread  30  is removed from the rear wall  13  of the drawer  10  by strongly pulling the thread  30 , and the thread  30  so separated from the trousers is allowed to be suspended in front of the trousers, whereby the viewer comes to recognize that any trick like one using a set thread is provided neither on the case main body  20  nor on the drawer  10 . Thus, the viewer cannot understand what type of trick is set on the matchbox and hence comes to feel more wonder.  
         [0050]     Note that while in the embodiment, only the outer drawer case  12  is drawn out of the case main body  20  or the outer drawer case  12  which is accommodating therein the inner accommodating case  11  is drawn out of the case main body  20  due to the principles illustrated in  FIG. 6 , any construction may be applied to the conjuring tool  1  of the present invention as long as the construction allows only the outer drawer case  12  to be drawn out of the case main body  20  or the outer drawer case  12  which is accommodating therein the inner accommodating case  11  to be drawn out of the case main body  20 , so that the wonder can be given to the viewer that an article appears all of sudden in the drawer  10  that has been confirmed empty before.  
         [0051]     Note that the thread may be fixed at one end thereof to a location below the rear wall of the drawer, passed under the drawer in the same manner as that described above and allowed to emerge from the interior of the case main body without using the double drawer structure. In this case, by performing the aforesaid operations, the wonder can be given to the viewer that the case main body moves and rises of itself on the hand and furthermore the drawer opens of itself on the hand without the viewer recognizing the existence of the thread.  
         [0052]     In addition, without using the double drawer structure but using the construction in which the rear wall of the drawer is allowed to slide upwardly, the thread may be fixedly held by the lower end of the rear wall of the drawer at one end thereof as has been described above, passed under the drawer as has been described above, and eventually caused to emerge from the inside of the case main body. In this case, by strongly pulling the thread so as to draw the drawer completely out of the case main body, the viewer can be made to recognize strongly that any trick such as one using a thread is set neither on the case main body nor on the drawer, thereby making it possible to make the viewer feel the wonder more.  
         [0053]     Note that the present invention is identical to what is described in Japanese Patent Application No. 2003-313832.
