DETAILED DESCRIPTION

(14) Referring now to FIGS. 1-4, an electric hair clipper suitable for use with the present flip-comb mechanism is generally designated 10, and as is well known in the art, includes a clipper housing 12 enclosing a motor, power system such as a battery, and a moving blade power transmission mechanism (all not shown). A clipper bladeset 14 includes a stationary blade 16 secured to the housing, and a laterally reciprocating moving blade 18. The stationary blade 16 includes a blade base 20 and a plurality of cutting teeth 22.

(15) The bladeset 14 is secured to the housing 12 using a bladeset bracket 24. The bladeset bracket 24 is generally “U”-shaped when viewed from the rear. Such bladeset brackets 24 are slidably engaged on the housing 12, in a preferred construction with edges 26 engaged in grooves 28 on the housing.

(16) Attached to the stationary blade 16 is the present flip comb mechanism generally designated 30, featuring a mount suitable for mounting an attachment comb 42 as described below to the hair clipper 10, and more particularly to the stationary blade 16. While several examples of a mount are presented by the following disclosure, it is contemplated by the instant invention that a “mount” as used herein may be any mechanical structure suitable for connecting an attachment comb (e.g. attachment comb 42) to a bladeset (e.g. bladeset 14) which allows a user to transition the attachment comb from an operational position wherein it is adjacent the bladeset to a non-operation position where it is displaced from the bladeset.

(17) In the illustration of FIGS. 1-4, the mount is in the form of a hinged bracket 31, which is held to the stationary blade by a pair of fasteners 32. Preferably, the fasteners 32 also secure the stationary blade 16 to the bladeset bracket 24. Included on the hinged bracket 31 is a first opposed flap 34, which is located between the fasteners 30 and the stationary blade 16 and is intended to keep the hinged bracket in place upon the hair clipper 10. Preferably, the first opposed flap 34 has a first handle 36.

(18) In addition, the hinged bracket 31 has a second opposed flap 38, which is preferably connected to a second handle 40. The handles 36, 40 are used, once grasped by the user, to rotate the second opposed flap 38 of the hinged bracket 31. An attachment comb 42 having a comb base 44 and a plurality of comb teeth 46 is attached to the second opposed flap 34. Within the hinged bracket 31, a biasing element, 48, preferably a spring, biases the hinged bracket so that, in a rest position, the attachment comb 42 is biased into a position that is adjacent the stationary blade 16 in an operational position such that a first mating plane P.sub.1 defined by the stationary blade 16 faces a second mating plane P.sub.2 defined by the attachment comb 42. When the handles 36, 40 are activated by the user, by squeezing them together, thus overcoming the biasing force of the spring 48, the second opposed flap 38 rotates away from the first opposed flap 34 and away from the stationary blade 16, thereby putting the hair clipper 10 in a non-operational state wherein the first and second mating planes P.sub.1, P.sub.2 are non-parallel as is shown in FIG. 2. By releasing the handles 36, 40 the hinged bracket 31 and the attachment comb 42 return to the operational position.

(19) Referring now to FIG. 2, the hair clipper 10 is shown in a non-operational position. Specifically, a user engages the first and second handles 36 40, which cause the second opposed flap 38 and the attachment comb 42 to rotate or pivot away from the first opposed flap 34 and the stationary blade 16.

(20) Referring now to FIGS. 3 and 4, the operation of the hair clipper 10 is shown when hair has been collected. Specifically, FIG. 3 shows the hair clipper 10 in an operational position, where hair 50 has been collected between the comb 42 and the stationary blade 16. As seen from FIGS. 3 and 4, there is a significant amount of hair 50 trapped between the comb 42 and the stationary blade 16, meaning that the hair must be cleared from the hair clipper 10 before proper operation may resume. Accordingly, FIG. 4 shows the hair clipper 10 in the non-operational position, with the handles 36, 40 actuated. Because the hair clipper 10 is in the non-operational position, the hair 50 easily removed.

(21) Referring now to FIGS. 5-8, another embodiment of the present flip comb mechanism is generally designated 60. Components shared with the flip comb mechanism 30 are designated with identical reference numbers.

(22) Attached to the stationary blade 16 is a mount in the form of a hinged bracket 62, which, like the bracket 31, is held to the stationary blade 16 by the pair of fasteners 32. The fasteners 32 also secure the stationary blade 16 to the bladeset bracket 24.

(23) Included on the hinged bracket 62 is the first opposed flap 34, which is located between, and vertically displaced from, the fasteners 32 and is intended to keep the hinged bracket 62 in place upon the hair clipper 10. In addition, the hinged bracket 62 has the second opposed flap 38, which is connected to the second handle 40. The handle 40, in conjunction with the handle 36 is used to rotate the second opposed flap 38 of the hinged bracket 62 away from the stationary blade 16.

(24) Referring now to FIG. 7, a main difference of the bracket 62 compared to the bracket 30 is a clip 64 is located on the second opposed flap 38 and one of a plurality of attachment combs 42 is removably attached to the clip 64. A variety of attachment formations is contemplated, including plug and opening, tongue and groove and the like as is well known in the art. In FIG. 7, the clip 64 is shown as a tongue 66, and the attachment comb 42 is provided with a socket 68.

(25) As is known in the art, attachment combs 42 are provided in a variety of sizes, each corresponding to a desired cutting length. The user can easily change the desired cutting length in the present clipper 10 by removing the comb 42 at the clip 64, and plugging in a new comb of a different size. Within the hinged bracket 62, the biasing element, 48, preferably a spring biases the hinged bracket 62 so that, in an operational position, the comb 42 is adjacent to, and depending upon the biasing force, optionally rests in contact with the stationary blade 16 such that the first mating plane P.sub.1 defined by the stationary blade 16 faces the second mating plane P.sub.2 defined by the attachment comb 42. When the handles 36, 40 are activated by the user and overcomes the biasing force of the spring 48, the second opposed flap 38 rotates away from the first opposed flap 34, thereby putting the hair clipper 10 in a non-operational state. In the non-operational state, the attachment comb 42 is held away from the stationary blade 16 such that the first and second mating planes P.sub.1, P.sub.2 are non-parallel as is shown in FIG. 8. Referring now to FIG. 8, in the non-operational or release position, any collected hair 50 obtained through the operation of the hair clipper 10 is easily removed by the user. By releasing the second handle 40, the hinged bracket 62 and the attachment comb 42 return to the operational position.

(26) Thus, by providing the present clip 64 and the hinged bracket 62, the present clipper 10 equipped with the flip comb mechanism 60 provides the user with the ability to rapidly removed collected hair and resume clipping. In addition, combs 42 are easily exchanged.

(27) Referring now to FIGS. 9-13, still another embodiment of the present flip comb mechanism is generally designated 70. Components shared with the mechanisms 30 and 60 are designated with identical reference numbers. A main distinctive feature of the flip comb mechanism 70 is the use of one or more magnetic elements to secure at least one and preferably both a hinged bracket and the attachment comb to the hair clipper 10, and more specifically, the stationary blade 16. These magnetic elements may take the form of any magnetic structure and may be designed to assume any shape to allow for mounting as described herein.

(28) Referring now to FIGS. 9 and 10, included on the mechanism 70 is a mount in the form of a hinged bracket 72 having a base plate 74 analogous to the first opposed flap 34, a hinge 76, and an attachment comb 78 with a base 79 analogous to the second opposed flap 38 which is connected to the base plate via the hinge. In other embodiments, it is contemplated that the hinged bracket 72 optionally includes other typical hair clipper attachments in lieu of the attachment comb 78, such as a blade guard (not shown). As is the case with the mechanisms 30 and 60, in the mechanism 70, the hinged bracket 72 is secured to the stationary blade 16 of the hair clipper 10. However, in a preferred embodiment of the mechanism 70, both the base plate 74 and the attachment comb 78 include magnets to removably couple to the stationary blade 16 of the hair clipper 10.

(29) More specifically, the base plate 74 has at least one and preferably a pair of base plate magnetic elements 80, also referred to as magnets, that releasably secure the hinged bracket 72 to the stationary blade 16. In FIG. 10, the attachment comb 78 is coupled to the stationary blade 16 in an operational position, with the base plate 74 uncoupled from the stationary blade and pivoted away from that blade about the hinge 76. It is preferred that the base plate magnets 80 project from an underside 82 of the base plate 74, however it is also contemplated that the magnets protrude through both sides of the base plate. It is also contemplated that the magnets 80 are embedded into the base plate 74 to be invisible to the user.

(30) A projection or handle 84 is secured to the base plate 74 and allows for increased control of the base plate 74 when hingedly rotating the base plate about the hinge 76. In the current example, the projection 84 is centrally located on the base plate 74 on the underside 82, however other locations are contemplated, and in some cases, the projection is considered optional. The depicted placement of the projection 84 allows for enhanced torque to be applied to the base plate 74 during rotation about the hinge 76.

(31) Referring now to FIG. 11, the base plate 74 is shown coupled to the stationary blade 16, while the attachment comb 78 is not coupled to the stationary blade, and instead is projecting at an approximate 90° angle thereto. As shown, the attachment comb 78 is hingedly rotated about the hinge 76 with respect to the base plate 74. As a result, both the teeth 22 of the stationary blade 16 and comb magnets 86 are visible. The comb magnets 86 enable removable coupling of the attachment comb 78 from the stationary blade 16. In some examples, the preferred plurality of comb magnets 86 are embedded in the comb 78 and are not visible.

(32) The flip comb mechanism 70 as shown in FIGS. 9-13 is configured to be fully coupled to the stationary blade 16, partially coupled to the stationary blade, or fully uncoupled from the blade. FIG. 10 shows that the flip comb mechanism 70, shown in an operational position such that first and second mating planes P.sub.1, P.sub.2 (see FIG. 11) defined by stationary blade 16 and attachment comb 78, respectively, face one another, is configured to be partially coupled to the stationary blade 16 even though the base plate 74 is rotated about the hinge 76 while the attachment comb 78 is coupled to the stationary blade 16. Referring now to FIG. 11, the flip comb mechanism 70 is optionally partially coupled to the stationary blade 16 in a hair clearing position, when the attachment comb 78 is rotated about the hinge 76 approximately 90 degrees, while the base plate 74 is coupled to the stationary blade 16. As can also be seen in this view, the attachment comb 78 is in its non-operational position such that the first and second mating planes P.sub.1, P.sub.2 are non-parallel.

(33) Referring now to FIGS. 12 and 13, the flip comb mechanism 70 facilitates the quick removal of hair clogged in the attachment comb 78. For example, FIG. 12 shows a side view of the flip comb mechanism 70 with both the attachment comb 78 and the base plate 74 coupled to the stationary blade 16. Hair 50 is caught between the attachment comb 78, the stationary blade 16, and/or the moving blade 18. Using the hair clipper 10 with so much trapped hair 50 in this state is undesirable and inefficient.

(34) Accordingly, FIG. 13 shows the present flip comb mechanism 70 with the attachment comb 78 hingedly rotated such that the hair 50 is released. The attachment comb 78, rotated relative to the stationary blade 16 so that it is only partially coupled to the blade, allows for a quick removal of the hair 50 and a quick recoupling of the attachment comb. This increases the efficiency with which users can cut hair in spite of long hair typically becoming caught in the attachment comb 78 or between the comb and the stationary blade 16.

(35) In an alternative embodiment, the flip comb mechanism 70 is merely an attachment comb 78 having the base plate magnets 80 disposed along a base of the comb teeth 46 that, when the comb is rotated 90° or at some other angle to the stationary blade 16, retain the comb at an elevated position for clearing of hair 50. Additionally, the attachment comb 78 is removably coupled to the stationary blade 16 by the comb magnets 86 which are secured to the comb teeth as seen in FIG. 11.

(36) Accordingly, when a user clears the attachment comb 78 of hair 50, the user pivots the attachment comb from being coupled to the stationary blade 16 via magnets 86 to being coupled via magnets 80. When the attachment comb 78 is coupled to the stationary blade 16 via magnets 80 on the base plate 74, the hair quickly falls from the hair clipper 10.

(37) While a particular embodiment of the present flip comb mechanism has been described herein, it will be appreciated by those skilled in the art that changes and modifications may be made thereto without departing from the invention in its broader aspects and as set forth in the following claims.
