DETAILED DESCRIPTION OF THE INVENTION
Reference will now be made to various embodiments of the present invention, examples of which are illustrated in the accompanying drawings wherein like numerals indicate the same elements throughout the views. Referring to Fig. 1, an electric toothbrush 20 will now be described. The electric toothbrush 20 may comprise a handle 22, a neck 24, and a head 26. The neck 24 may be integrally formed with the handle 22 or may be provided as a separate component. The handle 22 may have a cap 28 that threadably engages a portion of the handle 22. An electric motor 30 may be disposed within the handle 22 along with a voltage source. The voltage source may be provided in the form of one or more batteries 32 which may be received in a cradle 34 that may be disposed within the handle 22. The motor 30 may have a rotatable output shaft and an output gear 38 attached to the rotatable output shaft. The output gear 38 may engage a driven gear 40 which in turn may be operatively connected to a shaft 42 having a coupling 44 with an elongated slot 45 that may engage an eccentric post 37 of the driven gear 40. The slot 45 may be aligned along the longitudinal axis 47 of the shaft 42. The shaft may include a bushing 46 that may be captured by the handle 22 or neck 24. The bushing 46 may be formed of any flexible material that allows the shaft 42 to pivot about the bushing 46. Suitable materials can include elastomeric polymers, such as natural or synthetic rubbers. The bushing 46 may act as a pivot about which the shaft 42 moves. The location of the bushing 46 may be varied along the length of the shaft 42 in order to achieve a desired amount of side-to- side motion at the end of the shaft 42 adjacent the head 26. As the driven gear 40 rotates, the shaft 42 may pivot about the bushing 46 in a side-to-side motion (see Fig. 2). The side-to-side motion of the shaft 42 may occur substantially or entirely in a single plane.
Further as shown in Fig. 1, the head 26 may be made up of a top housing 70 (see Fig. 8), a middle housing 72, and a bottom housing 74. The head 26 may have a first free end 48 and a second end 50 that engages the neck 24. The head may include one or more carriers. The electric toothbrush 20 may comprise one or multiple carriers. A first carrier 52 may be disposed adjacent the first end 48 and a second carrier 54 may be disposed adjacent the second end 50. As shown in Fig. 3, the first carrier may oscillate about an axis 56 that is substantially perpendicular to a longitudinal axis 58 of the head 26. A shown in Fig. 4, the second carrier 52 may reciprocate in a side- to-side direction or motion perpendicular to the longitudinal axis 58 of the head 26. While the side-to-side motion shown in Fig. 4 may be substantially perpendicular to the longitudinal axis 58 of the head 26, it is contemplated that other side- to-side motions of the second carrier 52 can be provided. For example, the second carrier 52 might swing or pivot about a pin or hinge 53. As shown in Fig. 5, the pin or hinge 53 could be provided at other locations on the second carrier 52, such as at either end or in the middle to provide different types of side-to-side motions.
As shown in Figs. 6 and 7, the end 66 of the shaft 42 may operatively engage a slot 68 of the first carrier 54 to move the first carrier 54 in an oscillating motion about the axis 56. As shown in Fig. 8, the shaft 42 may pass through cam followers 60 of the second carrier 52. The cam followers 60 may receive a portion of the shaft 42. The cam followers 60 may be received in the slot 64 of the head 26, such that the slot 64 generally guides the second carrier 54 in its side-to-side motion.
A portion of the slot 64 may be flanked by flexible walls 76. The flexible walls 76 may be oriented transverse to the longitudinal axis 58 of the head 26. The flexible walls 76 may allow for movement of the second carrier 54 in a motion along the longitudinal axis 58 of the head 26 when the second carrier 54 is subjected to user forces. That is, when a user turns the toothbrush 20 on, the second carrier 54 may only move from side-to-side. However, when the user brushes her teeth, she will likely introduce forces which manipulate the second carrier 54 in directions and motions beyond the side-to-side motion. These forces will likely include ones which move the second carrier 54 generally along the longitudinal axis 58 of the head 26. The flexible walls 76 will allow the second carrier 54, to a degree, to travel along the longitudinal axis 58 of the head 26 (see Fig. 9). The motion of the second carrier 54 when manipulated by the user may be in the motion of an oval 78, a circle, etc., as such is consistent with standard brushing motions. When the second carrier 54 is not confined to a first motion (e.g., side-to-side relative to the longitudinal axis of the head), the battery power of the brush is normally preserved because the manipulative or biasing forces of the user when brushing or flossing her teeth are transferred into a second motion (e.g., along or in-line with the longitudinal axis of the head) instead of working against the first motion. Simply put, user forces which once worked against the first motion are now used to create a second, third, fourth, etc. motion.
The flexible walls 76 may not bias the second carrier 54 until user forces move the second carrier 54 against the flexible walls 76. This may be accomplished by orienting the flexible walls 76 immediately adjacent the second carrier 54, such that there is no room for the second carrier to float between the flexible walls. Also, a desired amount of space between the second carrier 54 and the flexible walls 76 may be left. Further, it may be desirable to use a single flexible wall 76, providing a more limited pathway for the second carrier 54 to travel upon when subjected to user forces.
It is also contemplated that the cam followers 60 may be fully surrounded by flexible walls 76, such that even the first motion of the second carrier 54 may be complemented by user forces, such that the side-to-side motion of the second carrier 54 may be widened by user forces.
Rather than making a part of the structure of the housings (e.g., 70, 72, and 74) of the head 26 flexible, like dynamics may be realized by making at least a portion of the cam follower 60 flexible. The cam follower 60 may comprise suitable materials including elastomeric polymers, such as natural or synthetic rubbers.
As shown in Fig. 10, the electric toothbrush 20 may comprise only a single carrier 80 which reciprocates along the longitudinal axis 58 of the head 26. The head 26 may comprise a main housing 82 having an elongated slot 64 running along its longitudinal axis 58. The slot 64 may have grooves 84 which receive tabs 86 of the receiving end 88 of the neck 24. The main housing 82 may also have a ball joint 90 which is received in an opening 92 of the neck 24. The carrier 80 may have an arm 90 which is fixed or operably connected to a spring clip 94.
The carrier 80 may be reciprocated along the elongated slot 64 by the shaft 42', and thus along or in-line with the longitudinal axis 58 of the head 26. As the carrier 80 moves in a motion along the elongated slot 64, the spring clip 64 may ride along a left side wall 96 and a right side wall 98 of the neck 24 such that a left leg 100 and a right leg 102 of the spring clip 94 is biased against the left side wall 96 and right side wall 98. Alternatively, the spring clip 64 may float between the right and left sidewalls 96 and 98.
The spring clip 64 may allow for movement of the carrier 80 in a motion transverse to the longitudinal axis 58 of the head 26 when the carrier 80 is subjected to user forces. That is, when a user turns the toothbrush 20 on, the carrier 80 may only move along the longitudinal axis 58 of the head 26. However, when the user brushes her teeth, likely manipulating the motion of the carrier 80 generally transverse to the longitudinal axis 58 of the head 26, the spring clip 64 may allow the carrier 80, to a degree, to travel transverse to the longitudinal axis 58 of the head 26. Thus, as the carrier 80 is moving along the longitudinal axis 58 of the head 26, it may also be moved transverse to the longitudinal axis 58 of the head 26. As the carrier 80 is subjected to user forces it may be pivoted around the arm 90. Thus, as shown in Figs. 11 and 12, as a front portion 104 of the carrier 80 is moved transverse to the longitudinal axis 58 of the head 26 in one direction, a back portion 106 of the carrier 80 is moved transverse to the longitudinal axis 58 of the head 26 in the opposite direction. The carrier 80 may be pivoted such that a longitudinal axis 116 of the carrier 80 is from about 5 to about 50 degrees, from about 15 to about 30 degrees, or from about 20 to about 25 degrees from a longitudinal axis 114 of the main housing 82 (el), whereas when the carrier 80 is not pivoted, its longitudinal axis 116 is generally in-line with the longitudinal axis 114 of the main housing 82, and thus generally in-line with the longitudinal axis 47 of the shaft 42'.
The spring clip 94 may bias the carrier 80 only slightly when no user forces are present, and more greatly once the carrier 80 encounters user forces. Alternatively, when no user forces are present, the spring clip 94 may float between the sidewalls 96 and 98 of the neck 24, such that the spring clip 94 does not bias the carrier 80 until user forces are present, forcing the spring clip 94 against a sidewall 96 or 98 of the neck 24, and thus biasing the carrier 80. As shown in Figs. 13 and 14, the carrier 80 may receive attachable/detachable bristle plates 108 or attachable/detachable floss plates 110.
