  The present invention relates to an electric clipper having a cutting head detachably attached to a front end of a main body case.

  An electric hair clipper in which a cutting head is detachably attached to the front end of the main body case is known in Japanese Patent Application Laid-Open No. 2003-122867. There, a cutting head incorporating a fixed blade and a movable blade is detachably attached to the main body case. On the front left and right of the main body case, and on the rear surface of the lower surface of the main body case, there are formed finger recesses. These finger hanging recesses are provided in order to fit the fingertips to the main body case according to the usage pattern of the clippers and make it easy to grip, and a switch knob is provided in one of the finger hanging recesses. A similar finger-hanging structure can also be seen in Patent Document 2, in which long bulging walls for dust prevention are provided on the front left and right of the main body case on the front and back, and an indented anti-slip part is formed near the rear. is doing.

  In the electric clipper of the present invention, the main body case and the head case attached to the main body case are unevenly bonded via a curved line-shaped bonding line. Such a bonding form is seen in the case structure of an electric razor. (Patent Document 3). In this case, a head frame having a pair of left and right side walls is bonded and fixed to the main body case. However, since both side walls of the frame are formed in a teardrop shape, both side walls and the main body case are joined in a curved line shape.

Japanese Patent Laid-Open No. 10-15263 (paragraph number 0014, FIG. 1) JP 2002-369882 (paragraph number 0027, FIG. 3) Japanese Patent No. 2838026 (paragraph number 0057, FIG. 15)

  In the electric clipper disclosed in Patent Document 1, the upper surface of the cutting blade unit is covered and concealed by a wall portion protruding from the main body case in a bowl shape. In the electric clipper of Patent Document 2, the upper case fixed to the main body case covers and conceals the upper surface of the cutting blade unit. When the upper surface of the clipper head is covered with the main body case or the upper case in this way, the longitudinal length of the main body case or the upper case becomes large, and the molding die is inevitably enlarged. By adopting a structure in which the clipper head part is covered with a dedicated head case made into an independent part, the molding die can be miniaturized and the main body case or the head case can be efficiently molded. However, there is a risk that the head case may vibrate or rattle due to the vibration of the cutting blade unit in use, so how can the head case made into an independent part be firmly attached and fixed to the main body case? Is a problem. With the conventional electric clipper with the cutting head removed, the upper surface of the cutting head is covered with the cover part, so that filings are likely to remain in the inner corner of the cover part, and it takes a lot of time for cleaning. There is room for improvement.

  An object of the present invention is to provide an electric hair clipper that can more firmly join and fix a head case as an independent part to a main body case and can be easily assembled. An object of the present invention is to provide an electric clipper that is easier to grip and use than a conventional electric clipper. The object of the present invention is to allow the head case covering not only the cutting head but also the periphery thereof to be easily removed from the main body case, so that the entire clipper head can be opened, and therefore the clipper head can be easily cleaned to every corner. It is to provide an electric clipper that can.

The electric clipper of the present invention includes a main body case 1 that is long in the front-rear direction, a drive unit 2 that is incorporated in the main body case 1, a cutting blade unit 3 that is detachably attached to the front portion of the main body case 1, and a main body case.

  The concavo-convex joint portion 50 is recessed toward the head case 24 corresponding to the joint projecting walls 51 and 53 projecting from the joint line S of the main body case 1 toward the head case 24 and the joint projecting walls 51 and 53. It is comprised by the junction recessed part 52 * 54 formed (Claim 2).

  Concave and convex portions 50 are formed at the front ends of the left and right side walls of the main body case 1, and concave portions 55 for hooking fingers are formed on the surface walls of the joint projection walls 51 of both the concave and convex portions 50.

  An uneven joint 50 is formed at the center of the front end of the upper wall of the main body case 1. The concavo-convex joint portion 50 includes a joint protrusion wall 53 that protrudes toward the head case 24 and a joint recess portion 54 that is recessed on the head case 24 side corresponding to the joint protrusion wall 53. Item 4). The outer shape of the joint projecting walls 51 and 53 in the uneven joint portion 50 is formed in a curved line shape (Claim 5).

  The finger hanging concave portion 55 is formed so as to be inclined downward from the rear end side of the concave portion toward the protruding end side of the joint protruding wall 51. Thus, the finger hooking step portion 56 is formed along the periphery of the joint protruding wall 51 (Claim 6).

  The decorative panel 4 is arranged on the outer surface of the upper wall of the main body case 1 including the joint protruding wall 53. The joint recess 54 is received and engaged with the joint projection wall 53 and the peripheral surface of the decorative panel 4 (Claim 7).

  A teardrop-shaped land portion 5 is bulged and formed on the front portion of the decorative panel 4, and a switch knob 6 is disposed on the outer surface thereof. An anti-slip step portion 57 is formed at the rear edge of the land portion 5 (claim 8).

The head case 24 is formed in a cylindrical shape including upper and lower walls 38 and 39 and left and right walls 40 and 41.
The front end edge of the upper wall 38 is located closer to the front end of the electric clipper than the front end edge of the lower wall 39. An opening 42 is formed between the front edge of the upper wall 38 on the front surface of the head case 24 and the front edge of the lower wall 39. The opening surfaces of the opening 42 defined by the left and right end portions of the front end edge of the upper wall 38 and the left and right end portions of the front end edge of the lower wall 38 are formed so as to be inclined obliquely downward and rearward. The cutting blade unit 3 is configured to be swingable between a posture for preventing the opening 42 and a posture for opening the opening 42 (claim 9).

  A mounting portion 43 of the head case 24 and an attachment portion 32 of the cutting blade unit 3 are formed on the head base 19 fixed to the front portion of the main body case 1. The clipper head can be opened in a state where the cutting blade unit 3 and the head case 24 are separated from the head base 19 (claim 10).

  The head base 19 is provided with a pair of left and right mounting portions 32 and a mount plate 20. A pair of left and right mounting portions 32 are supported from the left and right by a notch 35 provided in the mount plate 20 (claim 11).

  The mount plate 20 is provided with a pair of capture springs 33 that hold and fix the cutting blade unit 3 in a use posture. A part of the cutting blade unit 3 is engaged and held by the head case 24 attached to the attachment portion 43 so that the catching spring 33 and the head case 24 cooperate to fix and hold the cutting blade unit 3 in the use posture. (Claim 12).

  In the present invention, the head case 24 attached to the attachment portion 43 of the main body case 1 covers the peripheral portion of the cutting blade unit 3 to prevent frays and the like from entering the cutting blade unit 3 and its drive portion. I did it. In addition, an uneven joint 50 is provided on at least a part of the joint line S between the head case 24 and the main body case 1 so that vibrations acting on the head case 24 when the electric clipper is used are alternately engaged. Since it is received and dispersed at 50, it can be well prevented that the head case 24 mounted on the mounting portion 43 is rattled by vibration. There is also an advantage that the head case 24 can always be properly attached and attached by attaching and mounting the head case 24 to the main body case 1 with the uneven joint 50 as a mark.

  Using the bonding line S between the main body case 1 and the head case 24 as a position reference, the bonding protrusion walls 51 and 53 projecting from the bonding line S to the head case 24 side, and the bonding recess 52 formed to be recessed on the head case 24 side. If the concave / convex joint portion 50 is configured with 54, there is no case strength reduction that is unavoidable when the concave joint portions 52/54 are formed in the main body case 1 side. Moreover, even if a large external force or impact is applied to the head case 24 due to falling on the floor surface, the external strength is received by the joint projecting walls 51 and 53 that are continuous with the main body case 1, and the structural strength is increased. Since it can escape to the large main body case 1 side, distortion of the mounting posture of the head case 24 due to a drop impact and separation from the mounting portion 43 can be well prevented. (Claim 2).

  According to the electric clipper in which the concave and convex joints 50 are formed on the left and right side walls of the main body case 1, the left and right walls 40 and 41 of the head case 24 can be received by the pair of concave and convex joints 50. Thus, the head case 24 can be more securely held and fixed to prevent rattling. When the concave portions 55 for hooking the fingers are formed on the surface walls of the joint projection walls 51 of the both concave and convex joint portions 50, the thumb and index finger fingers are placed on the left and right concave portions 55 in a state where the electric clipper is held with one hand. By supporting the electric clipper, the entire posture of the electric clipper can be tilted up and down with the thumb and index finger as fulcrums, so that the operability of the electric clipper can be improved, for example, the hair can be easily cut along the scalp. Item 3).

  According to the electric clipper in which the concave / convex joint 50 is formed on the upper wall side of the main body case 1 in addition to the concave / convex joint 50 on the left and right side walls of the main body case 1, the concave / convex joint 50 provided at three locations is used for the head case 24. Since the movement is restricted in the vertical and horizontal directions, the vibration can be more effectively distributed to prevent the head case 24 from rattling, and the mounting posture of the head case 24 can be distorted or separated when subjected to a drop impact. Can be surely stopped. Since the three portions of the left and right side walls 40 and 41 and the upper wall 38 are engaged and captured by the uneven joint portion 50, the head case 24 can be firmly connected to the main body case 1. Since the head case 24 can be mounted on the mounting portion 43 with the concave-convex joint 50 provided on the upper wall side of the main body case 1 as a mark, the mounting direction of the head case 24 is not mistaken (claim 4).

  If the outer shape of the joint projecting walls 51 and 53 in the concavo-convex joint portion 50 is formed in a curved line shape, vibrations in all directions around the curved line can be evenly distributed. For example, the joint projecting walls 51 and 53 are formed in a rectangular shape. As compared with the case, the vibration and rattling of the head case 24 accompanying the reciprocating vibration of the cutting blade unit 3 can be effectively eliminated. (Claim 5).

  When the finger hanging concave portion 55 is formed to be inclined downward toward the protruding end side of the joint projecting wall 51 and the finger hanging step portion 56 is formed along the peripheral edge of the joint projecting wall 51, the fingertip applied to the concave portion 55 is pointed to the fingertip. It is possible to prevent the fingertip from protruding from the concave portion 55 by being received by the hanging step portion 56, and therefore, when using the electric clipper, the fingertip can always be fitted in a suitable use position specified by the concave portion 55 (Claim 6). ).

  According to the concavo-convex joint 50 in which the decorative panel 4 is arranged on the outer surface of the upper wall of the main body case 1 including the joint projecting wall 53 and receives and engages the joint recess 54 on the peripheral surface of the joint projecting wall 53 and the decorative panel 4. Since the movement of the head case 24 can be restricted by the cooperative action of the joint projection wall 53 and the decorative panel 4, the vibration restricting action can be further improved, and even when a large external force acts on the head case 24, the head case 24. It is possible to prevent well the distortion of the mounting posture and separation from the mounting portion 43 (Claim 7).

  When the teardrop-shaped land portion 5 is formed to bulge in the front portion of the decorative panel 4 and the switch knob 6 is disposed on the outer surface thereof, and the step portion 57 for preventing slipping is formed on the rear edge of the land portion 5, The land 5 where the switch knob 6 is disposed and the other surface of the decorative panel 4 can be clearly distinguished, and the step 57 can receive the fingertip and restrict the inadvertent movement of the fingertip. 6 can be prevented from being operated (claim 8).

  If the head case 24 is formed in a cylindrical shape including the upper and lower walls 38 and 39 and the left and right walls 40 and 41, the structural strength of the head case 24 can be increased, and the entire cylindrical wall constituting the head case 24 can be attached to the mounting portion 43. By fitting, the head case 24 can be more firmly connected to the main body case 1. When an oblique opening 42 is provided on the front surface of the head case 24 and the cutting blade unit 3 is exposed from the opening 42, the cutting blade unit 3 is opened and swung as necessary to clean fuzz and lubricate. Care can be easily performed (claim 9).

  A mounting portion 43 of the head case 24 and an attachment portion 32 of the cutting blade unit 3 are formed on the head base 19 fixed to the front portion of the main body case 1, and the cutting blade unit 3 and the head case 24 are attached to the head base 19. According to the electric clipper in which the hair clipper head can be opened in a state separated from the head base 19, the cutting blade unit 3 and the head case 24 removed from the head base 19 can be easily cleaned, as well as the head base 19 and the mounting plate. 20 and the shavings adhering to the drive shaft 18 or the like can be completely removed to keep the hair clipper head clean.
