DETAILED DESCRIPTION
Particular embodiments of an animated scissor holder will now be described in greater detail with reference to the figures.
FIG. 1 is a perspective view of a scissor holder 10 in a first position where a pair of scissors 14 are about to be inserted into an opening 24 in the holder 10 according to this subject disclosure. In this first position, a head 12 of the koala 17 is facing the opening 24.
For exemplary purposes, the scissor holder 10 resembles a koala 17 holding onto a tree 18. Although shaped as a koala 17 and a tree 18, it is to be understood that the scissor holder 10 can take a variety of different shapes. The housing 20 of the scissor holder is static, and the head 12 of the koala 17 is movable. For example, the scissor holder 10 may take the shape of other animals, vehicles, like a car, train, airplane, fire engine, raft, cruise ship, ferry boat, spaceship, rocket, stick of dynamite, cartoon bomb, a piece of fruit, a tree, a leaf, a globe and the like according to this subject disclosure.
FIG. 2 is a perspective view of the scissor holder 10 in an intermediate position with scissors 14 partially inserted into the opening 24 in the holder 10. In this intermediate position, the blade tip 16 of the scissors 14 have been inserted further into the opening 24 and the head 12 of the koala 17 has been partially turned from the first position in which the head 12 was facing the opening 24 of the housing 20.
FIG. 3 is a perspective view of the scissor holder 10 at a completely rotated second position with the scissors 14 fully inserted into the opening 24, and at rest within the scissor holder 10. In this second position, the head 12 of the koala 17 has turned approximately 90 degrees from the first position in which the head 12 was facing the opening 24 of the housing 20, into this final second position in which the head 12 of the koala 17 is turned sideways, facing forward.
FIGS. 4, 5 and 6 correspond to FIGS. 7, 8 and 9 respectively, and show rear views of the of the scissor holder 10 with a rear portion 22 of the housing 20 removed from the front portion 21. FIGS. 7, 8 and 9 show lower perspective views of rear views of the scissor holder 10 with a rear portion 22 of the housing 20 removed from the front portion 21. An animation gear assembly 25 is provided within the housing 20 to convert the linear motion of the insertion movement of the blade tips 16 into the sheath 26, into coordinated rotational motion through a drive gear 30 and a driven gear 50 to move the head 12 of the koala 17 from the first position (shown in FIG. 1), through the intermediate position (FIG. 2) and into to the second position (shown in FIG. 3) as will be described in more detail below.
In particular, FIGS. 4 and 7 show the blade tip 16 of the scissors 14 inserted into a guide or a sheath 26 and just beginning to engage an arm 32 of a drive gear 30. In this first position, the head 12 of the koala 17 is facing the opening 24 in the sheath 26.
FIGS. 5 and 8 shows the blade tip 16 of the scissors 14 inserted further into the sheath 26 at an intermediate position. In this intermediate position, the blade tips 16 of the scissors 14 have pressed against the arm 32 and caused it to rotate in a counterclockwise direction about a central pivot 34. The head 12 of the koala 17 is partially turned away from the first position in which the head 12 of the koala 17 was facing the opening 24 in the sheath 26.
FIGS. 6, 9 and 10 shows the blade tip 16 of the scissors 14 is fully inserted into the sheath 26. In this second position, the scissor 14 is in a storage position. That is, the blade tips 16 of the scissors 14 have pressed in as far as they can go within the sheath 26. The blade tips 16 press against the arm 32 causing it to rotate as far as it could in the counterclockwise direction about a central pivot 34 until the arm 32 engages the arm stop 38. In this second position shown in x-ray in FIG. 10, in which the face of the koala 17 is forward facing, the head 12 of the koala 17 is completely rotated and turned away from the first position at approximately 90 degrees from the first position which faced the opening 24 in the sheath 26.
As shown in FIGS. 4-5, a spring 42 is provided on the drive gear 30 and connected to the arm 32 and a projection 31 on the housing 20. Within the animated gear assembly 25, the spring 42 is positioned to provide a spring bias force to the arm 32 of the drive gear 30 so that when the weight of the scissors 14 pressing at the blade tips 16 onto the upper surface 33 of the arm 32 has been removed from the housing 20, the animated gear assembly 25 will return to its first position. That is, the driven gear 50 and the arm 32 on the drive gear 30 will rotate clockwise back from the second position into its first position, thereby returning the head 12 of the koala 17 back to its original direction in the first position.
FIGS. 11 and 12 illustrate front internal views of the scissor holder 10 within the front portion 21 of the housing 20. The head 12 of the koala 17 is in the first position facing the opening 24. The rear portion 22 of the housing 20 has been removed so that the internal structure of the scissor sholder 10 can be better viewed. FIGS. 11 and 12 shows the internal view of the scissor holder 10 in the first position with the head 12 of the koala 17 facing the opening 24 and with the scissors 14 disposed within the sheath 26.
As shown, the blade tip 16 of the scissors 14 has been inserted into the opening 24 of the sheath 26 sufficiently far enough to engage the arm 32. The arm 32 is configured as a circular drive gear 30 that rotates around the central pivot 34. Drive teeth 36 are disposed on peripheral surface of the drive gear 30. When the blade tip 16 comes into contact with an upper surface 33 of the arm 32 on the drive gear 30, the drive gear 30 rotates about the central pivot 34 in a clockwise direction and mates with a driven gear 50. The driven gear 50 is integrated onto a lower end of the head 12 of the koala 17. The driven gear 50 is radially positioned in a plane that is perpendicular to a rotating plane that the drive gear 30 turns within.
Referring back to FIGS. 11 and 12, within the animated gear assembly 25, the housing 20 has a pair of stops 40, 38 that are located at a predetermined position to prevent the blade tips 16 of the scissors 14 from travelling too far within the housing 12. Likewise, the length of travel of the blade tips 16 within the housing 20 corresponds to the rotational movement necessary to rotate the koala's head 12 from a first desired position (shown in FIGS. 1, 4 and 7), through the intermediate position (shown in FIGS. 2, 5 and 8), and into a final desired second position (shown in FIGS. 3, 6 and 9).
According to this subject disclosure, in the second position, the head 12 of the koala 17 is approximately 90 degrees from the first position. It is to be understood that the animated animal or object may be rotated at any preferred degree according to this subject disclosure.
As shown, the arm stop 38 is provided below the arm 32 a substantial distance and acts as a barrier stop when the arm 32 is rotated a predetermined rotational distance corresponding with turning the head 12 of the koala at approximately 90 degrees. A blade stop 40 is also provided within the housing. A combination of the positioning of the blade stop 20 and the arm stop 38 prevent the blade tips 16 from advancing further within the housing 20 at a predetermined distance within the housing 20 when a lower surface 35 of the arm 32 backs up against the arm stop 38. That is, the blade stop 40 and the arm sop 38 permits the blade tips 16 to be positioned within the housing 20 at an optimal depth to securely hold the blade tips 16 in place within the sheath 26. It is also to be understood that the pair of stops 40, 38 may be constructed in a variety of different ways as shown. It is also possible to configure the stops 40, 38 as a single integrated stop which can serve the same purpose.
In particular, in the animated gear assembly 25, the drive gear 30 is circular and has the arm 32 extending from one side of the drive gear 30 that engages the ends of the blade tips 16. An opposite side of the drive gear 30 has a plurality of drive gear teeth 36 on its periphery. The linear motion of the blade tip 16 of the scissors 14 being placed into the sheath 26 is converted into a rotational motion through the drive gear 30 around the central pivot 34. The drive gear teeth 36 engage the driven gear teeth 51 on the driven gear 50.
As shown in FIGS. 11, 12 and 13-14, the driven gear 50 rotates in a second plane perpendicular to a first plane in which the drive gear 30 rotates within. As shown in FIG. 13, the drive gear 30 rotates about a first axis X that is perpendicular to a second axis Y that the driven gear 50 rotates around. This rotational connection transfers the impact engagement of the blade tips 16 against the arm 32 to be transferred through the drive gear 30 around the first axis X into the driven gear 50 which rotates around the second axis Y. This translation of movement causes the head 12 of the animal to rotate from the first position, through the intermediate position and coming to a resting at the second position.
FIGS. 11-14 show the driven gear 50 having a set of driven gear teeth 51 attached to an axle 52 at a first end, and a key 54 attached to a second end of the axle 52. As best shown in FIG. 13, the key 54 is positioned and fixed within a receiving slot 13 constructed within the head 12. When the driven gear 51 is rotated (on the Y axis) by the drive gear 30 (rotating on the X axis), the axle 52 and the key 54 are moved from the first position through the intermediate position to the third position along the second rotational axis Y, which in turn turns the head 12 of the koala 17 when the blade tip 16 of the scissors 14 is completely inserted into the sheath 26.
FIGS. 11 and 13 more clearly illustrate various weights 28 that can be positioned within the housing 20. The weights 28 disposed in the housing 20 will secure the housing 20 in an upright position when the weight of the scissors 14 are inserted in the sheath 26. The weights 28 disposed at the lower end will prevent the upper end of the holder 10 from becoming too top heavy when the scissors 14 are inserted into the sheath 26.
