That is, Japanese Utility Model Registration No. 3023663 describes to the effect that, by inserting amain brush 110 and asub-brush 116 into afeeding bottle 150, rotating ahandle 114 as a main driving shaft, and as a result of the rotation being transmitted to a connectingmember 113 serving as a driven shaft, themain brush 110 and thesub-brush 116 rotate with the rotation of thehandle 114 to be able to clean the inside of thefeeding bottle 150. - However, the cleaning brush described in Japanese Utility Model Registration No. 3023663 is rotated with the handle gripped, and there has been a demand for a tool that allows rotating a brush or the like more simply, by only fingertips.
- The present invention has been made in view of the above, and an object thereof is to provide a rotary tool capable of easily causing a to-be-rotated body to rotate by only the fingertips.
- In order to achieve the object described above, a rotary tool of the present invention is a rotary tool including a first longitudinal member that is turnable in forward and reverse directions about a first axis substantially perpendicular to a plane on which a to-be-rotated body is disposed, a second longitudinal member that is turnable in forward and reverse directions about a second axis that is substantially parallel to or substantially the same as the first axis of turning of the first longitudinal member, and opposed to the first longitudinal member across a region in which a to-be-rotated body is disposed, a rotating means disposed between the first longitudinal member and the second longitudinal member, and for causing a to-be-rotated body to rotate with a turn of the first longitudinal member and a turn of the second longitudinal member, and an elastic member disposed between the first longitudinal member and the second longitudinal member, and attached to the first longitudinal member and the second longitudinal member, in which the rotating means is located on one side with respect to a boundary of the first axis or the second axis in a region between the first longitudinal member and the second longitudinal member, the elastic member is located on the other side with respect to a boundary of the first axis or the second axis in a region between the first longitudinal member and the second longitudinal member, and the first longitudinal member and the second longitudinal member turn so that the distance between each other's end portions present at the same side with respect to a boundary of the first axis or the second axis varies.
- Here, the first axis of turning of the first longitudinal member and the second axis of turning of the second longitudinal member are substantially parallel to or substantially the same as each other, the second longitudinal member is opposed to the first longitudinal member across a region in which a to-be-rotated body is disposed, and by the rotating means that is disposed between the first longitudinal member and the second longitudinal member, and causes the to-be-rotated body to rotate with a turn of the first longitudinal member and a turn of the second longitudinal member, the to-be-rotated body can be caused to rotate by only grasping by fingers and a thumb the first longitudinal member and the second longitudinal member.
- Moreover, the rotary tool of the present invention can be one including a rod-shaped to-be-rotated body to be caused to rotate by the rotating means, and having a plurality of projection portions at at least one end.
- Moreover, the rotary tool of the present invention can be one in which the rotating means is a first elastic that is attached to the first longitudinal member and the second longitudinal member, and wound around the to-be-rotated body, and the elastic member is a second elastic that is attached to the first longitudinal member and the second longitudinal member, and wound around the to-be-rotated body.
- In this case, when the distance between the first longitudinal member and the second longitudinal member is reduced by grasping by fingers and a thumb the first longitudinal member and the second longitudinal member, with respect to a boundary of the first axis or the second axis, at the side where the second elastic serving as an elastic member is attached, the distance between the first longitudinal member and the second longitudinal member, with respect to a boundary of the first axis or the second axis, at the side where the first elastic serving as a rotating means is attached increases, and the first elastic wound around the rod-shaped to-be-rotated body is accordingly pulled to cause the to-be-rotated body to rotate.
- Due to the rotation of the to-be-rotated body, the second elastic wound around the rod-shaped to-be-rotated body further winds around the to-be-rotated body, and a biasing force is further applied to the second elastic. Then, when the grasping force of the fingers and thumb that have grasped the first longitudinal member and the second longitudinal member at the side where the second elastic is attached is reduced, the second elastic tries to restore due to the biasing force, and the second elastic wound around the to-be-rotated body causes the to-be-rotated body to rotate.
- Moreover, the rotary tool of the present invention can be one in which the rotating means is a first elastic that is attached to the first longitudinal member and the second longitudinal member, and wound around the to-be-rotated body, the elastic member is a second elastic that is attached to the first longitudinal member and the second longitudinal member, and attached to the to-be-rotated body to be windable therearound, the first longitudinal member at a side where the second elastic is attached with respect to a boundary of the first axis is provided with a first finger hole to pass through fingers or a thumb, and the second longitudinal member at a side where the second elastic is attached with respect to a boundary of the second axis is provided with a second finger hole to pass through fingers or a thumb.
- In this case, because fingers and a thumb can be inserted into the first finger hole and the second finger hole, a force can be applied, by extending the fingers and thumb, also in a direction to separate the end portion of the first longitudinal member and the end portion of the second longitudinal member from each other.
- Moreover, the rotary tool of the present invention can be one including a turning support to which the first longitudinal member and the second longitudinal member are turnably attached and in which a through-hole is provided, in which the to-be-rotated body is inserted through the through-hole.
- The rotary tool according to the present invention is capable of easily causing the to-be-rotated body to rotate by only the fingertips.

FIG. 1 , therotary tool 1 of the present invention includes a firstlongitudinal member 2 and a secondlongitudinal member 3 opposed to the firstlongitudinal member 2 across a region in which a to-be-rotated body is disposed. - Moreover, both end portions of each of the first
longitudinal member 2 and the secondlongitudinal member 3 are curved toward the side opposite to the region in which a to-be-rotated body is disposed. As a result, a substantially central portion of each of the firstlongitudinal member 2 and the secondlongitudinal member 3 is a curved portion. - Moreover, the

first hook portion 6A and thesecond hook portion 6B has a structure in which two end portions located in directions different by 180° from each other are curved toward theturning support 11. - Moreover, the end portions of the
first hook portion 6A and the end portions of thesecond hook portion 6B are located in directions different by 90° from each other (i.e. located within two orthogonal planes). - Moreover, also at an outer peripheral surface of the rod-shaped portion of the rod-
shaped brush 6 that is located on the other side with respect to a boundary of thefirst axis 9 or thesecond axis 10 in the region between the firstlongitudinal member 2 and the secondlongitudinal member 3, athird hook portion 6C and afourth hook portion 6D are attached. - Here, each of the
third hook portion 6C and thefourth hook portion 6D has a structure in which two end portions located in directions different by 180° from each other are curved toward theturning support 11. - Moreover, the end portions of the
third hook portion 6C and the end portions of thefourth hook portion 6D are located in directions different by 90° from each other. - Moreover, the
rotary tool 1 of the present invention includes a first elastic (which is an example of a rotating means) 4 that is disposed between the firstlongitudinal member 2 and the secondlongitudinal member 3, and causes the rod-shaped brush 6 to rotate with a turn of the firstlongitudinal member 2 and a turn of the secondlongitudinal member 3. - Moreover, the first elastic 4 is located on one side with respect to a boundary of the
first axis 9 or thesecond axis 10 in the region between the firstlongitudinal member 2 and the secondlongitudinal member 3. - Here, the first elastic 4 consists of a first
elastic band 4A that is attached to one end of the firstlongitudinal member 2 and one end of the secondlongitudinal member 3 and caught on thefirst hook portion 6A to be wound around the rod-shaped brush 6, a secondelastic band 4B that is attached to one end of the firstlongitudinal member 2 and caught on thesecond hook portion 6B to be wound around the rod-shaped brush 6, and a third elastic band 4C that is attached to one end of the secondlongitudinal member 3 and caught on thesecond hook portion 6B to be wound around the rod-shaped brush 6. - Moreover, the
rotary tool 1 of the present invention includes a second elastic (which is an example of an elastic member) 5 that is disposed between the firstlongitudinal member 2 and the secondlongitudinal member 3, and attached to the firstlongitudinal member 2 and the secondlongitudinal member 3. - Moreover, the second elastic 5 is located on the other side with respect to a boundary of the
first axis 9 or thesecond axis 10 in the region between the firstlongitudinal member 2 and the secondlongitudinal member 3. - Here, the second elastic 5 consists of a fourth
elastic band 5A that is attached to the other end of the firstlongitudinal member 2 and the other end of the secondlongitudinal member 3 and caught on thefourth hook portion 6D to be wound around an end portion of the rod-shaped brush 6, a fifthelastic band 5B that is attached to the other end of the firstlongitudinal member 2 and caught on thethird hook portion 6C to be wound around the rod-shaped brush 6, and a sixth elastic band 5C that is attached to the other end of the secondlongitudinal member 3 and caught on thethird hook portion 6C to be wound around the rod-shaped brush 6. - Moreover, in
FIG. 1 , the first elastic 4 and the second elastic 5 are different from each other in winding direction, but are the same in the number of windings. -
FIG. 2 is a schematic view showing a state where the rotary tool shown inFIG. 1 rotates a rod-shaped brush in a forward direction. - Moreover,
FIG. 3 is a schematic view showing a state where the rotary tool shown inFIG. 1 rotates a rod-shaped brush in a reverse direction. - As shown in
FIG. 2 , when near the other end of the firstlongitudinal member 2 and the other end of the secondlongitudinal member 3 are grasped by fingers and a thumb, the firstlongitudinal member 2 turns about thefirst axis 9 and the secondlongitudinal member 3 turns about thesecond axis 10, so that the distance between the other end of the firstlongitudinal member 2 and the other end of the secondlongitudinal member 3 decreases. - Simultaneously therewith, the distance between one end of the first
longitudinal member 2 and one end of the secondlongitudinal member 3 increases, and the first elastic 4 (the firstelastic band 4A, the secondelastic band 4B, and the third elastic band 4C) wound around the rod-shaped brush 6 is accordingly pulled to cause the rod-shaped brush 6 to rotate in aforward direction 12. - At this time, due to the rotation of the rod-
shaped brush 6 in theforward direction 12, the second elastic 5 (the fourthelastic band 5A, the fifthelastic band 5B, and the sixth elastic band 5C) wound around the rod-shaped brush 6 further winds around the rod-shaped brush 6, and a biasing force is further applied to the second elastic 5 (the fourthelastic band 5A, the fifthelastic band 5B, and the sixth elastic band 5C). - Then, as shown in
FIG. 3 , when the grasping force of the fingers and thumb that have grasped near the other end of the firstlongitudinal member 2 and the other end of the secondlongitudinal member 3 is reduced, the second elastic 5 (the fourthelastic band 5A, the fifthelastic band 5B, and the sixth elastic band 5C) wound around the rod-shaped brush 6 tries to restore due to the biasing force, and the second elastic 5 (the fourthelastic band 5A, the fifthelastic band 5B, and the sixth elastic band 5C) wound around the rod-shaped brush 6 causes the rod-shaped brush 6 to rotate in areverse direction 13. - At this time, due to the rotation of the rod-
shaped brush 6 in thereverse direction 13, the first elastic 4 (the firstelastic band 4A, the secondelastic band 4B, and the third elastic band 4C) again winds around the rod-shaped brush 6 to return to the state as shown inFIG. 1 . - Thereafter, by again grasping by fingers and a thumb near the other end of the first
longitudinal member 2 and the other end of the secondlongitudinal member 3 as shown inFIG. 2 and reducing the grasping force of the fingers and thumb that have grasped near the other end of the firstlongitudinal member 2 and the other end of the secondlongitudinal member 3 as shown inFIG. 3 in the same way, the rod-shaped brush 6 can be repeatedly rotated in the forward and reverse directions. -
FIG. 4 is a schematic view showing a second embodiment of a rotary tool of the present invention. - Moreover.
FIG. 5 is a schematic view showing a state where the rotary tool shown inFIG. 4 rotates a rod-shaped brush in a forward direction. - As shown in
FIG. 4 , in therotary tool 1 of the second embodiment of the present invention, a firstlongitudinal member 2 at a side where a second elastic 5 is attached with respect to a boundary of afirst axis 9 is provided with afirst finger hole 2B to pass through fingers or a thumb, and alongitudinal member 3 at a side where a second elastic 5 is attached with respect to a boundary of asecond axis 10 is provided with asecond finger hole 3B to pass through fingers or a thumb. - Moreover, near the
first finger hole 2B of the firstlongitudinal member 2, a first projection portion 2C projecting toward the secondlongitudinal member 3 is provided. - Moreover, near the
second finger hole 3B of the secondlongitudinal member 3, a second projection portion 3C projecting toward the firstlongitudinal member 2 is provided. - Moreover, similar to the first embodiment, at an outer peripheral surface of a rod-shaped portion of the rod-shaped
brush 6, afirst hook portion 6A, asecond hook portion 6B, athird hook portion 6C, and the fourth hook portion GD are attached, however, in the second embodiment, end portions of these hooks are all located in the same direction (within the same plane). - Moreover, the first elastic 4 consists of a first
elastic band 4A and a secondelastic band 4B. - The first
elastic band 4A is attached to one end of the firstlongitudinal member 2 and one end of the secondlongitudinal member 3, and caught on thefirst hook portion 6A to be wound around the rod-shapedbrush 6. - The second
elastic band 4B is attached to a substantially midpoint between one end of the firstlongitudinal member 2 and thefirst axis 9 and a substantially midpoint between one end of the secondlongitudinal member 3 and thesecond axis 10, and caught on thesecond hook portion 6B to be wound around the rod-shapedbrush 6. - Moreover, the second elastic 5 consists of a fourth
elastic band 5A and a fifthelastic band 5B. - Here, the fourth
elastic band 5A is attached to aseventh hook portion 6C attached to the inside of the firstlongitudinal member 2, that is, a side closer to the rod-shapedbrush 6 and an eighth hook portion 6H attached to the inside of the secondlongitudinal member 3, that is, a side closer to the rod-shapedbrush 6, and caught on thefourth hook portion 6D to be attached to the rod-shapedbrush 6 so as to be windable therearound. - Moreover, the fifth
elastic band 5B is attached to a fifth hook portion 6E attached to the inside of the firstlongitudinal member 2 and asixth hook portion 6F attached to the inside of the secondlongitudinal member 3, and caught on thethird hook portion 6C to be attached to the rod-shapedbrush 6 so as to be windable therearound. - The other aspects are the same as those of the first embodiment.
- As shown in
FIG. 5 , when fingers and a thumb are passed through thefirst finger hole 2B and thesecond finger hole 3B and the firstlongitudinal member 2 and the secondlongitudinal member 3 at the side where the second elastic 5 (the fourthelastic band 5A and the fifthelastic band 5B) is attached are moved so as to become close to each other, the firstlongitudinal member 2 turns about thefirst axis 9, and the secondlongitudinal member 3 turns about thesecond axis 10, so that the distance between the other end (the side where the second elastic 5 is attached) of the firstlongitudinal member 2 and the other end (the side where the second elastic 5 is attached) of the secondlongitudinal member 3 decreases. - Moreover, because there is provided a first projection portion 2C and a second projection portion 3C, a certain distance is maintained between the other end of the first
longitudinal member 2 and the other end of the secondlongitudinal member 3 even when the distance therebetween is minimized. - Simultaneously therewith, the distance between one end of the first
longitudinal member 2 and one end of the secondlongitudinal member 3 increases, and the first elastic 4 (the firstelastic band 4A and the secondelastic band 4B) wound around the rod-shapedbrush 6 is accordingly pulled to cause the rod-shapedbrush 6 to rotate in aforward direction 12. - At this time, due to the rotation of the rod-shaped
brush 6 in theforward direction 12, the second elastic 5 (the fourthelastic band 5A and the fifthelastic band 5B) attached to the rod-shapedbrush 6 so as to be windable therearound winds around the rod-shapedbrush 6, and a biasing force is applied to the second elastic 5. - That is, the second elastic 5 is wound around the rod-shaped
brush 6 in a winding direction different from the first elastic 4. - Then, when a force is applied to the first
longitudinal member 2 and the secondlongitudinal member 3 by extending the fingers and thumb passed through thefirst finger hole 2B and thesecond finger hole 3B simultaneously with reducing the force of the fingers and thumb to bring the firstlongitudinal member 2 and the secondlongitudinal member 3 at the side where the second elastic 5 (the fourthelastic band 5A and the fifthelastic band 5B) is attached close to each other, the second elastic 5 (the fourthelastic band 5A and the fifthelastic band 5B) wound around the rod-shapedbrush 6 tries to restore due to the biasing force and the force in a direction to extend the fingers and thumb, and the second elastic 5 (the fourthelastic band 5A and the fifthelastic band 5B) wound around the rod-shapedbrush 6 causes the rod-shapedbrush 6 to rotate in a reverse direction. - Then, due to the rotation of the rod-shaped
brush 6 in the reverse direction, the first elastic 4 (the firstelastic band 4A and the secondelastic band 4B) again winds around the rod-shapedbrush 6 to return to the state as shown inFIG. 4 . - At this time, the distance between the other end of the first
longitudinal member 2 and the other end of the secondlongitudinal member 3 increases. Moreover, because fingers and a thumb pass through thefirst finger hole 2B and thesecond finger hole 3B, a force to keep apart from each other the firstlongitudinal member 2 and the secondlongitudinal member 3 at the side where the second elastic 5 (the fifthelastic band 5A and the fifthelastic band 5B) is attached can also be applied by extending the fingers and thumb. -
FIG. 6 is a schematic plan view showing a third embodiment of a rotary tool of the present invention. - Moreover,
FIG. 7 is a schematic front view showing a third embodiment of a rotary tool of the present invention. - In
FIG. 6 , therotary tool 1 of the present invention includes a firstlongitudinal member 2 and a secondlongitudinal member 3 opposed to the firstlongitudinal member 2 across a region in which a rod-shapedbrush 6 serving as a to-be-rotated body is disposed. - Moreover, the first
longitudinal member 2 and the secondlongitudinal member 3 cross each other three-dimensionally, and are turnably connected at this intersection point by across-connecting portion 14. - Further, the intersection point corresponds to a
first axis 9 of the firstlongitudinal member 2, and also corresponds to asecond axis 10 of the secondlongitudinal member 3. - Moreover, as shown in
FIG. 6 , one end of the firstlongitudinal member 2 and one end of the secondlongitudinal member 3 are opposed to each other, and have tabular fan shapes. - Moreover, the
rotary tool 1 of the present invention includes anouter frame 19 disposed so as to surround one end of the firstlongitudinal member 2 having a fan shape and one end of the secondlongitudinal member 3 having a fan shape. - Moreover, as shown in
FIG. 7 , therotary tool 1 of the present invention includes a gear wheel (which is an example of a rotating means) 16 disposed between the fan-shaped one end of the firstlongitudinal member 2 and the fan-shaped one end of the secondlongitudinal member 3, and as apparent also fromFIG. 6 , thegear wheel 16 is located on one side with respect to a boundary of the first axis 9 (or the second axis 10) in a region between the firstlongitudinal member 2 and the secondlongitudinal member 3. - Moreover, at a substantially center portion of the
gear wheel 16, a through-hole 16A through which the rod-shapedbrush 6 is inserted is provided. Moreover, because the inner diameter of the through-hole 16A is substantially the same as the outer diameter of the rod-shaped portion of the rod-shapedbrush 6, the rod-shapedbrush 6 rotates with a rotation of thegear wheel 16. - Moreover, in the third embodiment, at an outer peripheral surface of a rod-shaped portion of the rod-shaped
brush 6, no such hook portions as in the first embodiment and the second embodiment are provided. - Also, in
FIG. 7 , illustration of a rod-shaped brush is omitted. - Moreover, as shown in
FIG. 6 , the fan-shaped one end of the firstlongitudinal member 2 and the fan-shaped one end of the secondlongitudinal member 3 are located on one side with respect to a boundary of the first axis 9 (or the second axis 10) of thecross-connecting portion 14, and the other end of the firstlongitudinal member 2 and the other end of the secondlongitudinal member 3 are located on the other side with respect to a boundary of the first axis 9 (or the second axis 10) of thecross-connecting portion 14. - Moreover, a
lateral support bar 20 that penetrates through a space surrounded by theouter frame 19 in the lateral direction (width direction) and alongitudinal support bar 21 that penetrates through the space surrounded by theouter frame 19 in the longitudinal direction (height direction) are respectively, at their both ends, fixedly secured to theouter frame 19. - Also, in
FIG. 6 , illustration of an outer frame with the end portions of thelongitudinal support bar 21 fixedly secured is omitted. - Moreover, at an intersection point between the
lateral support bar 20 and thelongitudinal support bar 21, a through-hole (which is not shown) through which the rod-shapedbrush 6 is inserted is provided, and the through-hole is located on substantially the same axis as that of the through-hole 16A of thegear wheel 16, and has an inner diameter slightly larger than the inner diameter of the through-hole 16A. - Moreover, as shown in
FIG. 6 , in the fan-shaped one end of the firstlongitudinal member 2 and the fan-shaped one end of the secondlongitudinal member 3, a first through-hole 2A and a second through-hole 3A through which thelongitudinal support bar 21 is passed are provided, respectively. - Moreover, as shown in
FIG. 7 , at a surface of the fan-shaped one end of the firstlongitudinal member 2 that makes contact with thegear wheel 16, a firstuneven portion 17 that meshes with the teeth of thegear wheel 16 is provided, and at a surface of the fan-shaped one end of the secondlongitudinal member 3 that makes contact with thegear wheel 16, a seconduneven portion 18 that meshes with the teeth of thegear wheel 16 is provided. - Moreover, the
rotary tool 1 of the present invention includes a leaf spring (which is an example of an elastic member) 15 that is disposed between the firstlongitudinal member 2 and the secondlongitudinal member 3, and attached to the firstlongitudinal member 2 and the secondlongitudinal member 3. - Moreover, the
leaf spring 15 is located on the other side with respect to a boundary of thefirst axis 9 or thesecond axis 10 in the region between the firstlongitudinal member 2 and the secondlongitudinal member 3. - Then, when near the other end of the first
longitudinal member 2 and the other end of the secondlongitudinal member 3 are grasped by fingers and a thumb, the firstlongitudinal member 2 and the secondlongitudinal member 3 turn about the first axis 9 (or the second axis 10) of thecross-connecting portion 14, and the other end of the firstlongitudinal member 2 and the other end of the secondlongitudinal member 3 move in a first movingdirection 22A of the other end, so that the distance between the other end of the firstlongitudinal member 2 and the other end of the secondlongitudinal member 3 decreases. - At this time, the
leaf spring 15 is compressed, and a restoring force (biasing force) is applied to theleaf spring 15. - Simultaneously therewith, one end of the first
longitudinal member 2 and one end of the secondlongitudinal member 3 move in a first movingdirection 22 of one end. - Then, the teeth of the
gear wheel 16 and the firstuneven portion 17 provided at one end of the firstlongitudinal member 2 and the seconduneven portion 18 provided at one end of the secondlongitudinal member 3 mesh with each other, and thegear wheel 16 rotates in a firstrotating direction 24 to rotate the rod-shapedbrush 6 in the same firstrotating direction 24. - On the other hand, when the grasping force of the fingers and thumb that have grasped near the other end of the first
longitudinal member 2 and the other end of the secondlongitudinal member 3 is reduced, due to the biasing force of theleaf spring 15 that has been compressed, the firstlongitudinal member 2 and the secondlongitudinal member 3 turn about the first axis 9 (or the second axis 10) of thecross-connecting portion 14, and the other end of the firstlongitudinal member 2 and the other end of the secondlongitudinal member 3 move in a second movingdirection 23A of the other end, so that the distance between the other end of the firstlongitudinal member 2 and the other end of the secondlongitudinal member 3 increases. - Simultaneously therewith, one end of the first
longitudinal member 2 and one end of the secondlongitudinal member 3 move in a second movingdirection 23 of one end. - Then, the teeth of the
gear wheel 16 and the firstuneven portion 17 provided at one end of the firstlongitudinal member 2 and the seconduneven portion 18 provided at one end of the secondlongitudinal member 3 mesh with each other, and thegear wheel 16 rotates in a second rotating direction (direction opposite to the first rotating direction) 25 to rotate the rod-shapedbrush 6 in the same secondrotating direction 25. - Thereafter, in the same way, by grasping by fingers and a thumb near the other end of the first
longitudinal member 2 and the other end of the secondlongitudinal member 3 and reducing the grasping force of the fingers and thumb that have grasped near the other end of the firstlongitudinal member 2 and the other end of the secondlongitudinal member 3, the rod-shapedbrush 6 can be rotated in the first rotating direction and second rotating direction. - In the above examples, a description has been given of a rod-shaped brush raised as an example of a to-be-rotated body, but the to-be-rotated body is not necessarily a rod-shaped brush, and for example, a simple helicopter-like bamboo toy (Taketonbo) may be used as the to-be-rotated body, and the rotary tool of the present invention can also be used as a toy.
- As in the above, according to the rotary tool of the present invention, the first axis of turning of the first longitudinal member and the second axis of turning of the second longitudinal member are substantially parallel to or substantially the same as each other, the second longitudinal member is opposed to the first longitudinal member across a region in which a to-be-rotated body is disposed, and by the rotating means (such as a gear wheel or a first elastic) that is disposed between the first longitudinal member and the second longitudinal member, and causes the to-be-rotated body (such as a rod-shaped brush) to rotate with a turn of the first longitudinal member and a turn of the second longitudinal member, the to-be-rotated body can be caused to rotate by only grasping by fingers and a thumb the first longitudinal member and the second longitudinal member.
- Therefore, the rotary tool of the present invention is capable of easily causing the to-be-rotated body to rotate by only the fingertips.
- Moreover, the first elastic serving as a rotating means is located on one side with respect to a boundary of the first axis or the second axis in the region between the first longitudinal member and the second longitudinal member, and the second elastic serving as an elastic member is located on the other side with respect to a boundary of the first axis or the second axis in the region between the first longitudinal member and the second longitudinal member, and thus, when the distance between the first longitudinal member and the second longitudinal member is reduced by grasping by fingers and a thumb the first longitudinal member and the second longitudinal member, with respect to a boundary of the first axis or the second axis, at the side where the second elastic is attached, the distance between the first longitudinal member and the second longitudinal member, with respect to a boundary of the first axis or the second axis, at the side where the first elastic is attached increases, and the first elastic wound around the rod-shaped brush is accordingly pulled to cause the rod-shaped brush to rotate.
- Due to the rotation of the rod-shaped brush, the second elastic wound around the rod-shaped brush further winds around the rod-shaped brush, and a biasing force is further applied to the second elastic. Then, when the grasping force of the fingers and thumb that have grasped the first longitudinal member and the second longitudinal member at the side where the second elastic is attached is reduced, the second elastic tries to restore due to the biasing force, and the second elastic wound around the rod-shaped brush causes the rod-shaped brush to rotate.
- Thereafter, by only repeatedly grasping by fingers and a thumb the first longitudinal member and the second longitudinal member at the side where the second elastic is attached and reducing the grasping force, the rod-shaped brush can be continuously rotated.
- Moreover, because the rotary tool of the second embodiment of the present invention provided with a first finger hole and a second finger hole allows inserting fingers and a thumb into the first finger hole and the second finger hole, a force can be further applied, by extending the fingers and thumb, also in a direction to separate the end portion of the first longitudinal member and the end portion of the second longitudinal member from each other.
- Moreover, similarly in the rotary tool of the third embodiment of the present invention including a gear wheel and a leaf spring, by only grasping by fingers and a thumb the first longitudinal member and the second longitudinal member at the side where the leaf spring is attached and reducing the grasping force, the gear wheel is rotated in the first rotating direction and the second rotating direction so that the rod-shaped brush can be continuously rotated.
