Abstract:
A ballpoint pen stand decorated with a movable ornament comprises a movable ornament, an ornament seat, a pen barrel, a pen cap, an ink cartridge, and a plurality of lead cords. When the writer takes off the pen cap, presses down the pen barrel, the top lid and the mount will come down too. It therefore shortens the distance between the top lid and the spring collar, the lead cords are loosened, rendering all limbs and joints of the ornament to sag. On the contrary, when the pressure is released, the lead cords are tightened up, the limbs and joints of the ornament recover to position. These successive action produce funny effect while writing with it.

Description:
BACKGROUND OF THE INVENTION 
     The prior art of ballpoint pen stand achieves the funny effect as usual by means of static sound or light, never presenting in dynamic mood. Nowadays, the such an action effect only takes place on the joint toys such as puppet toy having joints and limb assembled with pivot member and manually manipulated to dispose the toy at the desired position. However, most of them still lack interaction, least interesting at all. In addition the complicated structure of the joint toy renders high production cost. 
     SUMMARY OF THE INVENTION 
     A ballpoint pen stand decorated with a movable ornament in accordance with this invention comprises a movable ornament, an ornament base, a pen barrel under the ornament base, a pen cab sleeved on the end of the pen barrel, an ink cartridge placed in the center of the pen barrel, and a plurality of lead cords for controlling the movable ornament. The ornament base is further composed of a top lid, a spring, a spring collar and a mount where the mount holds the top end of the pen barrel, the top lid and the mount are joined together, in between there fills with a spring and a spring collar. The spring collar intimately pushes the top end of the ink cartridge and the spring sits between the top lid and the spring collar. The movable ornament consists of a plurality of limbs and point, inked together by a plurality of lead cords. The lead cords pass downward through the holes of the top lid and around the spring collar and finally to be tightened there. During the writing with such a ballpoint pen, pressing or retracting the lead cords will excite the movable ornament to ascent or descent for fun.

     DETAILED DESCRIPTION OF THE INVENTION 
     The invention will be explained in great detail with the aid of some embodiments of the drawings. 
     FIG. 1 shows the stereo disassembly of the funny ballpoint pen stand of the invention, displaying the composition of ballpoint ball stand  10 , which constitutes a movable ornament  1 , an ornament base  2  beneath the ornament, a pen barrel  3  under the ornament base  2 , a pen cap  31  under the pen barrel, an ink cartridge  32  placed in the hollow center of the pen barrel  3 , and a plurality of lead cords  4  which are employed to manipulate the movable ornament  1 . The complete assembled ball point pen stand is shown in FIG.  2 . 
     FIG. 3 illustrate the assembled section of the ballpoint pen stand of the invention. The ornament base  2  constitutes a to top lid  21 , a spring  22 , a spring collar  23  and a mount  24 . Beneath the top lid  21 , there provides a protruded round ring  211  and a go through hole  212 . The spring collar  23  has a raised rim  231 , two side grooves  232 , a projected chute  233  under the bottom and a slot  234  going through two sides of the projected chute  233 . The upper end of the spring  22  pierces into the protruded round ring  211  and the lower end perches on the outer edge of the raised rim  231 . The top lid  21  has a projected collar  213  on the bottom, and the mount  24  has inward round groove  241 . When the top lid  21  is pushed downward onto the mount  24 , the projected collar  213  will fix into the inward round groove  241  to provide sufficient space for housing both the spring  22  and the spring collar  23 . 
     The aforesaid mount  24  has a go through aperture  242  and an extended tube  243  which accommodates the upper end of the pen barrel  3 . The pen cap  31  installed at the end of the pen barrel  3  fits perfectly with the barrel head  33 . The ink cartridge  32  will pass the aperture  242  of the mount  24  and rests in the projected chute  233  of the spring collar  23 . 
     Please refer to FIGS. 3 and 4. FIG. 4 illustrates the complete assembly of movable ornament and lead cords and the relationship between the movable ornament  1 , a plurality of lead cords  4  and the spring collar  23 . Where the movable ornament  1  consists of a base plate  11 , two lower limbs  12 , a body composed of a front shell  13  and a back shell  14 , a neck joint  15 , a head  16 , two upper limb joints  17 , and two upper limbs  18 . 
     The detail structure of the movable ornament is characterized in that: one long slot  111  on the base plate  11 , two small holes  121  through two lower limbs  12 , respectively. Above the lower limbs  12 , there are two lateral lock tubes  131  fastened on the opening of the raised frame  132  in the semi-circle front shell  13 . Two lateral lock rods  141  are fastened on the opening of frame groove (not shown) of the semi-circle rear shell  14 , so two shells  13  and  14  are fixed symmetrically by inserting the lock rods  141  into the lock tubes  131 . On the neck joint  15 , there are two rectangular tenons  153  on both sides and two go through holes  151 . On the head  16 , there provides a hollow cylinder  161  and two rectangular mortises  162  to receive the two tenons  153  the neck joint  15 . On each side of shell  13  and  14 , two small holes  171  are provided to connect to the two upper limb joints  17  individually. Each upper limb  18  has a hollow cylinder  181  inside. The joints are linked by means of several lead cords  4 . 
     As described above, the lock tube  131  in the front shell  13  receives the insert of the lock rod  141  of the back shell  14 , furthermore, the raised frame  132  fits into the frame groove  142  to form a toy body. The body periphery furnishes five guide holes, one neck guide hole  191 , two upper limb guide holes  192  and two lower limb guide holes  193 . Three lead cords  41  through  43  are used to link them together. The lead cord  41  is a leading cord, starting in the neck joint  15  with a knot  411 . Two lead cords  41  pass two guide holes  151 , entering successively the neck guide hole  191 , the lower limb guide hole  193 , the small hole  121  on the lower limbs  12 , the guide hole  111  on the base plate  11 , the small hole  211  on the top lid  21 , the side groove  232  on the spring collar  23 , finally turning around bottom projected chute  233  and the slot  234 . Finally pulling the lead cord very tightly, the tenons  153  fits in the mortises  162  and so the head  16  is secured steadfastly onto the neck joint  15 , the neck joint  15  onto the shells  13  and  14 , the shells  13  and  14  onto two lower limbs  12 , and two lower limbs  12  on the base plate  11 . 
     Other two lead cords  42  and  43  are auxiliaries. These two lead cords begin in the left and right upper limb joints  17  having individual knot  421  and  431  at each end, running in parallel downward through two small holes  171  on the upper limb joints  17 , the upper limb guide hole  192 , the lower limb guide hole  193 , the small hole  121  on the lower limb  12 , the guide hole  111  on the base plate  11 , the small hole  211  on the top lid  21 , the side groove  232  on the spring collar  23 , turning around the slot  234  of the projected chute  233 , finally pulling two lead cords  42  and  43  tightly, causing the upper limb joint  17  secured onto the shells  13  and  14 , and the upper limb joint  18  on the upper limb  17 . The assembly is well done. 
     As shown in FIG. 5, the ballpoint pen is under pressing. If the writer wants to use the ballpoint pen  10 , he has to take off the pen cap  31 , contacts the pen tip of the ink cartridge  32  on the surface of a piece of paper. At this moment, when the ballpoint pen  10  is pressed down and the pressure applied is greater than the resistance of the spring  22 , the spring is contracted and slid downward along with the top lid  21 , the mount  24 , the ornament  1  and the pen barrel  3  (similarly the ink cartridge  32  and the spring collar are uplifting.) Whereas the distance between the spring collar  32  and the top lid  21  is shortened, three lead cords  4  are thereby loosened, both the limbs and joints of the ornament will naturally sag down as shown in FIG.  6 . 
     FIG. 7 illustrates that the pressure applied to the ballpoint pen  10  is released. 
     Once the applied pressure is released, the spring  22  regains the elasticity and pushes the top lid  21  and the mount  24  along with the ornament  1  and the pen barrel  3  up, the lead cords are pulled straightly tight, all components return to the original positions as shown in FIG.  8 . 
     Repeated practice of such an action will make the ornament  1  on the ballpoint pen  10  movable. The ornament specified in the invention is not confined to a single pattern, it can be different animals or toys to make the funny effect changeable. Taking a bird for an example, with wings and face, by mechanical linkage, it produces a flying bird. Such a simple design change will render abundant derivatives. To an artist, such a design change is easy and very simple. The design and application of control cord to stir an action on an ornament belong to the scope of this invention. 
     The invention has achieved the following remarkable results. 
     1. The ballpoint pen stand serves as a writing tool and a decoration. 
     2. The interaction of the lead cord and the ornament will produce a wide variety of actions, such as jumping, swinging and quivering. 
     3. It requires no battery and circuit control and it presents no environmental nuisance. 
     4. Simplified structure, low cost and easy to produce for mass production. 
     5. The interaction of pen and ornament will invite the attention and curiosity from children who will consequently develop greater thinking.
