Description

Clipping device and comb unit {CLIPPING DEVICE AND COMB UNIT}

The present invention relates to a clipping device used for cutting hair, cutting a beard or pushing an animal's hair and a comb unit for such a clipping device.

Clipping devices are widely used to cut hair, especially short hair, hair around the ears, and to cut beards. For example, a dog or other animal such as a poodle can also be cut with the aid of a clipping device.

A commonly used clipping device has a cutting unit with two blades that are moved relative to each other with the aid of a motor. The cutting device is generally mounted on a case that houses a motor or a battery as a power source for the clipping device. To define the correct cutting length, the comb unit is mounted on a case covering the cutting unit. The actual cutting length is defined by the length of the teeth of the cutting unit. The hair length is equal to the blade's distance to the skin where the comb unit fixed on the case is applied for cutting.

Another important parameter is the cut width. The constant cutting width is limited by the width of the blades and is particularly suitable for cutting large areas such as the beard on both cheeks or the hair on top of the head. In some cases when cutting a mustache or hair around the ear, the cutting width may be too large for accurate cutting without risking plaque on the skin. Another case where a wider cutting width is rather inconvenient is when first testing whether the actual cutting length is appropriate.

US 6,378,210 B1 proposes a solution to this problem. A pattern designer shaver system is described that includes a base unit for many users to drive trimmers and shaver attachments that are removable by multiple users of varying widths. Each trimmer attachment has internal hair trimmer attachment screws that match well with conventional hair trimmer heads and base unit screws, which can be connected to an off-set output shaft by a bottom-shaped attachment slot. And a housing with a trimmer having a base unit coupling having an internal thread thereon. Trimmer attachments are practically identical except for the trimmer width.

The main drawback of this solution is the technically complex coupling of the trimmer attachment to the base unit, which tends not to move properly.

It is an object of the present invention to provide an improved clipping device and a comb unit for such a clipping device.

In a first aspect, the present invention relates to a case, a cutting unit at one end of a case comprising at least one cutting member that provides a given cutting width, and to the cutting member to cover the cutting member to reduce the cutting width. It provides a clipping device comprising a cover means to be mounted. The cover means may consist of a single part or a combination of other parts.

The clipping device according to the invention provides a wide range of possible applications, since the cutting width is varied with the aid of the cover means. Clipping devices equipped with cover means are particularly useful for removing a lot of hair or for testing the cutting length without trimming or cutting the hair, for example with high precision around the ear. The clipping device with the cover means removed allows the maximum cutting width. The reduced cutting width is achieved by the cover means without the need for complex trimming with various trimmer attachments as in the prior art.

In a preferred embodiment of the invention, the cover means is configured as a comb unit detachable to the case and / or the cutting unit. The cover means detachably connected to the comb unit can be replaced with a conventional comb unit if the maximum width is required. Preferably, the comb unit comprises a toothed portion in a closed gap covering the cutting member. This allows the hair to be cut to stand up and is actually achieved and cut by the cutting unit not only in the hair but also in the part of the comb unit with teeth with closed gaps.

The cover means may be removable or fixed to the cutting unit and / or the case. In a preferred embodiment, when the cover means is fixed, it can be moved between a position providing a given cutting width and a position providing a reduced cutting width. By fixing, the cover means cannot be lost or forgotten. It is then preferably integrated into the cutting unit, preventing damage to the cover means. The attached cover means has the advantage of low production costs and can be provided with various cover means of different sizes to define different cutting widths for one cutting unit.

In a preferred embodiment, the cover means can comprise two or more portions, the reduced cutting width being substantially equal to the distance between the two portions. By pushing, actuating or mounting the two parts, it is easily possible to switch between reduced and unreduced cutting widths.

In a preferred embodiment, the cover means comprise at least two parts which are independently movable in a direction perpendicular to the cutting member, each defining a reduced cutting width. This is particularly convenient when another user is using the same clipping device, some are left-handed, some are right-handed, or if the user wants to cut hair around one back and then hair around another ear. .

In a preferred embodiment, the cover means is movable in a direction substantially parallel to the cutting member in order to change the position of the covered member of the cutting member with respect to the case. This embodiment is also particularly useful when another user uses the same clipping device, some are out-handed, some are right-handed, or the user cuts hair around one ear and hair around the other ear. It is convenient.

In another aspect, the invention provides a comb unit for a clipping device according to the invention, which can be detached to a case and / or to a cutting unit to cover a cutting member of one or more cutting units for reducing the cutting width. The invention includes a toothed portion with a closed gap covering the cutting member. This has the advantage that the comb unit according to the invention can be replaced with a conventional comb unit according to the required cutting width.

Preferred embodiments of the invention are described herein with reference to the drawings.

The case 2 houses the connection unit to the external power supply via the wire 6 (see FIG. 2) for supply to the motor and battery or motor. It may be a rechargeable battery unit. The motor drives the blade 31 of the cutting unit and is best seen in FIG. 2. Most clipping devices generally have two blades that are moved longitudinally relative to each other by a motor for cutting. The motor is switched on / off with the aid of the switch 5. It will be appreciated that the present invention can be applied to any clipping device regardless of the configuration of the cutting member (s) 31 of the cutting unit 3.

The length of the blade defines the maximum cutting width that can be reduced with the aid of the cover means 4. In the particular example shown in FIGS. 1 and 2, the cover means 4 are arranged as a comb unit 41. The comb unit 41 is attached, ie removably connected to the housing of the cutting unit 3. When the comb unit 41 is attached to the cutting unit 3, the comb unit is, in this case, with the aid of the left and right parts of the teeth 411 with the closed gap 412, the cutting unit 3. Cover the blade 31. The comb unit 41 stands up the hair to be cut, only the hair between the left and right sides of the comb unit 41 with the teeth 411 with the closed gap 412 being actually held by the blade 31. Will be reached and cut. Thus, the distance between the left and right portions of the comb unit 41 with the teeth 411 and the closed gap 412 defines a reduced cutting width.

The clipping device shown in FIGS. 1 and 2 is particularly useful for testing the cutting length without removing much hair. The actual cutting length depends on the position of the comb unit 41 relative to the blade 31. 1 shows the comb unit 41 in the position for the minimum cutting length, and FIG. 2 shows the comb unit 41 in the position for the maximum cutting length. After testing the cutting lengths of the various positions of the comb unit 41 and determining the cutting length to be advanced, the comb unit 41 is removed, the conventional comb unit is attached to the clipping device 1, and the conventional comb unit is Maximum cutting width is allowed.

An illustration of the comb unit 41 according to the invention is shown in more detail in FIGS. 3 and 4. 3 shows the inverted shape, ie the side touching the skin. 4 shows the same perspective view of FIGS. 1 and 2. It is to be noted that when the comb unit 41 is attached, the gap 412 between the teeth 411 on the left side and the right side is closed so that the blade 31 of the cutting unit 3 is covered. Attachment can be accomplished by a snapping mechanism. When the comb unit 41 is pressed over the cutting unit 3, the fixing part 413 is guided in a direction parallel to the case, and can be snapped at various positions along the direction, and each snapping position is arbitrary. Same as the cutting length. It will be appreciated that any known attachment method may be used to attach the comb unit 41 to the case 2 or the cutting unit 3.

A more preferred embodiment is shown in FIG. According to this example, the cover means consists of a shade 42 which is integral to the cutting unit 3. The shade 42 widens the opening of the cutting unit 3 next to the blade 31 in order to allow the maximum cutting width. If the user only wants to cut with a reduced cutting width, the shade 42 can be pushed in the direction perpendicular to the blade 31 and after use, can return to the cutting unit 3. The movement of the shade 42 can be controlled electrically or mechanically, for example using a small handle on the side of the cutting unit 3.

Another preferred embodiment is shown in FIG. 6. According to this example, the cover means 4 are arranged as a cover 43. This cover 43 can be partially attached to the cutting unit 3 covering the blade 31 when necessary. Preferably, the shade 43 is attached using a snapping mechanism. However, of course, it can also attach by other attachment methods using a magnet or the like. More preferably, the attachment is in the direction parallel to the blade 31 so that the shade 43 changes the position of the reduced cutting width from the side to the left side of the right part of the cutting unit 3 or vice versa (see arrow). It is made so that it can be moved. It is particularly convenient when another user uses the same clipping device, some are left-handed, some are right-handed, or if the user wants to cut around one ear and the other to cut hair around the other ear. In another preferred embodiment, the shade 53 may not be movable, but may move in a direction parallel to the blade 31.

The preferred embodiment shown in FIGS. 5 and 6 is particularly convenient when trimming and cutting hair with high precision. One advantage of the example shown in FIG. 5 is that the cover means 4 are not lost and cannot be lost. An advantage of the example shown in FIG. 6 is that the cost of production is less than most other embodiments, and various covers 43 of different sizes are provided to define different cutting widths for one cutting unit 3 and The side of the blade 31 with reduced cutting width can be freely selected.

7 and 8 schematically illustrate a variant of the embodiment of FIG. 5. The first shader 421 and the second shader 422 widen the cutting unit 3 under the blade 31 and allow for a maximum cutting width defined by the length of the blade 31. In addition, the conventional comb unit 7 is attached to the cutting unit 3. It should be understood that all embodiments can be used in combination with conventional comb units, unlike embodiments with cover means arranged as a comb unit.

If the user wants to use only a reduced cutting width, he pushes both shades 421 and 422 with the help of pushing means 423. The distance between the shade 421 and the shade 422 defines the cutting width. Preferably, the shades 421 and 422 are inside the cutting unit 3 to prevent damage to the shades 421 and 422. The pushing means 423 can be actuated by the user from the outside with the aid of the grip 424. It will be appreciated that the pushing means 423 can also be operated in other ways, such as, for example, electricity.

9 and 10 schematically show a second variant of the embodiment shown in FIG. 5. Again, there is a first shade 421 and a second shade 422 widened in the cutting unit 3. However, in this variant, the two shades 421 and 422 can be moved independently of one another as shown in FIG. 10. Each shade 421, 422 can be moved separately with the aid of a respective grip 424. Instead of manually moving the shades 421, 422 with the aid of the grip 424, they can be electrically operated, for example, with the aid of a switch. 9 and 10 cause the position of the reduced cutting width to change from left to right or vice versa of the cutting unit. Symmetrical shades 421 and 422 can be used to provide different cutting widths on both sides.

It will be appreciated that there may be simpler variants with only one shade or more complex variants with more shades than two shades. All embodiments may be varied for the number of parts of the cover means.

11-13 schematically illustrate a more preferred embodiment of the present invention based on a single shade 44. This shade 44 can be attached to the cutting unit 3 and can also be exchanged with other shades of different sizes, or can be fixed, for example, to the cutting unit 3 in a non-removable manner. The shape of the single shade 44 and the guidance 442 in which the single shade slides are adapted to each other so that the single shade 44 can be in three separate positions: the three positions are on the right side of the cutting unit 3. The position for the reduced cutting width, the position for the reduced cutting width on the left side of the cutting unit 3, the position for the maximum cutting width. In this example, triangular shade 44 that is aligned with triangular guidance 442 is selected, resulting in an overall movement that is substantially parallel to blade 31. The user can grip the grip 441 and manually move the single shade 44 by pushing the shade 44 in the desired direction. As with other embodiments, other methods of operating and moving the shade 44 are possible.

It will be appreciated that in all embodiments based on the shade, the shade can be mounted outside or inside the cutting unit 3. There may be shades on either or both sides of the cutting member. Preferably the shade should be positioned so as to be between the cutting member and the hair to be cut when in operation.
