{Comb Attachment for Hair Clippers Enabling to Adjust Length of Hair Cut}

The present invention relates to an extra blade used with a hair clipper.

Hair clippers, commonly called baricangs, are currently commonly used in beauty salons as well as in general homes. These hair clippers are usually used with an additional blade attached to prevent the length of hair left after a haircut from becoming too short.

Specifically, this additional blade is also called a clipper jack, which is added to the cutting blade portion of the clipper and allows the cutting blade of the clipper to be spaced a predetermined distance from the scalp. As a result, the length of hair remaining after a haircut, that is, the length from the scalp to the tip of the hair, is approximately the same as the height of the clipper blade.

According to this configuration of the clipper blade, when a hair designer wants to cut hair and leave only the desired length, he must separately provide an additional blade for the clipper with a height that exactly matches the length. Accordingly, most beauty salons are currently equipped with three or more blades for clippers, each with a different blade height. In addition, most of the extra blades for clippers currently on the market are sold as a series of more than five separate standard products with different heights.

According to this configuration, there is the inconvenience of having to frequently replace the blades of the appropriate size whenever the hair designer wants to change the length of the haircut. In addition, each time you replace an additional blade, you must first separate the inserted additional blade, and the additional blade may be easily damaged by dropping it during this separation process. On the other hand, since the blades are composed of multiple blades, users sometimes place the blades of a size that is less frequently used in a separate storage location, but there is also the problem of easily losing the blades of that size because they often forget where to store them.

The purpose of the present invention is to provide, in addition to the hair clipper, an extra blade for a hair clipper that allows the hair clipper to freely adjust the hair cutting length and cut without replacing the extra blade.

This is a drawing showing the blade 100 as seen from the front.

Referring to these drawings together, the extra blade 100 for a hair clipper includes a fixing unit 110 and an extra blade unit 150.

Here, the fixing unit 110 includes a plate 111, an attachment pad 113, an inner rail 115, and a fixing protrusion 117.

The plate 111 is fixed to the clipper (C). Specifically, the clipper (C) may be positioned on the main surface of the plate (111) so that its cutting blade (B) is exposed on the side of the leading edge area of the plate (111).

The attachment pad 113 is configured to secure the plate 111 to the clipper (C). Specifically, the attachment pad 113 is added to the main surface of the plate 111 and performs the function of attaching the plate 111 to the clipper (C). In addition to the attachment pad 113 shown in these drawings, another configuration for fixing the plate 111 to the clipper C may be applied to the fixing unit 110. As an example, a configuration in which the plate 111 is detachably fixed to the clipper C through a locking piece and an elastic bracket installed on the plate 111 may also be applied.

The inner rail 115 may extend along the longitudinal direction of the plate 111 on the main surface of the plate 111. The inner rail 115 may have an inverted trapezoidal cross-section protruding from the lower main surface of the plate 111 as shown in FIG. 4 .

A plurality of fixing protrusions 117 are arranged on the side of the plate 111 along the inner rail 115. The fixing protrusions 117 may be arranged at intervals of 2 mm to 5 mm.

Meanwhile, the extra blade unit 150 includes a body 151, wings 153, a fixing groove 155, an extra blade member 157, and an out rail 171.

The body 151 is located below the fixing unit 110.

Wing portion 153 extends from the side of body 151. Specifically, the wings 153 extend to face the side of the plate 111 and are spaced apart from the side of the plate 111 by a predetermined distance.

The fixing groove 155 is formed in the wing portion 153. The fixing groove 155 may have a shape corresponding to the fixing protrusion 117 so that the fixing protrusion 117 can be seated.

The extra blade member 157 is configured to guide the hair. The extra blade member 157 includes comb teeth 159 and comb grooves 161.

A plurality of comb teeth 159 each extend from the tip of the body 151 along the longitudinal direction of the body 151. In addition, each comb tooth 159 may have an approximately triangular shape. Through this appearance, the comb teeth 159 have a height that gradually decreases toward the end. In addition to this external shape, the comb teeth 159 may have an external shape in which the lower area is a convex curve.

The comb groove 161 is a groove formed between adjacent comb teeth 159 and is an area where hair guided by the comb teeth 159 gathers.

The out rail 171 is a configuration that allows the body 151 and the extra blade member 157 to move with respect to the fixing unit 110. The out rail 171 includes a main rail 173, a sub rail 175, and a stopper 177.

Through this configuration, the body 151 and the extra blade member 157 slide only forward and backward with respect to the fixing unit 110, and are prevented from moving or leaving in any other direction. In addition, due to the structure surrounding the inner rail 115 on three sides, the blade unit 150 is more firmly fixed to the fixing unit 110.

The sub rail 175 is formed at the top of the comb teeth 159. The sub rail 175 has the same height as the main rail 173 so that the main rail 173 and its main surfaces are located on one plane. Through this configuration, the inner rail 115 can slide beyond the body 151 to the comb teeth 159.

The stopper 177 is located at the end of the sub-rail 175. The stopper 177 prevents the inner rail 115 from falling toward the end of the comb teeth 159.

Hereinafter, the operation method of the extra blade 100 for a hair clipper capable of adjusting the hair cutting length will be described in detail with reference to FIGS. 5 and 6.

FIG. 5 is an operating diagram showing the extra blade 100 for the hair clipper with adjustable hair cutting length of FIG. 1 as seen from above, and FIG. 6 shows the extra blade 100 for the hair clipper of FIG. 1 as seen from the side. It also works.

First, the blade unit 150 may be located at the first point P1 with respect to the fixing unit 110, as shown in FIGS. 5 and 6. In this way, when the extra blade unit 150 is located at the first point P1, the shortest distance from the cutting blade B to the lower end of the comb teeth 159 forms the first height H1.

When hair cutting is performed in this state, only the portion of the hair gathered in the comb groove 161 that protrudes above the comb teeth 159 is cut by the cutting blade B. The length of hair remaining after such cutting, specifically the length from the scalp to the tip of the hair, constitutes the first length. Here, the first length is equal to the first height H1, which is the shortest distance from the cutting blade B to the bottom of the comb teeth 159.

Meanwhile, the length of the first height H1 may vary depending on the position at which the cutting blade B is fixed to the plate 111. Specifically, when the cutting blade B of the clipper C is located as close as possible to the top of the comb teeth 159, which is the area of the sub rail 175, beyond the tip edge of the plate 111, the first height H1 is It may be equal to the length corresponding to the height H1 of the comb teeth 159 at the first point P1.

Therefore, the first length, which is the length of the hair remaining on the scalp when the blade unit 150 is located at the first point (P1), is a length corresponding to the height (H1) of the comb teeth 159 at the first point (P1). It may be the same as

Meanwhile, according to the extra blade 100 for a hair clipper capable of adjusting the hair cutting length according to an embodiment of the present invention, the extra blade unit 150 is configured to slide with respect to the fixing unit 110.

Specifically, when the user holds the blade unit 150 and pushes or pulls it with a predetermined force, the fixing protrusion 117 seated in the fixing groove 155 falls out from it. Thereafter, the extra blade unit 150 moves while sliding relative to the fixing unit 110 according to the rail directions of the inner rail 115 and the outer rail 171. Thereafter, when the extra blade unit 150 reaches the second point P2, which is the position desired by the user, another fixing protrusion 117 is seated in the fixing groove 155. As a result, the extra blade unit 150 is fixed to the second point P2.

On the other hand, since this sliding movement is achieved by the inner rail 115 and the outer rail 171 having an inverted trapezoidal cross-section, the blade unit 150 is fairly rigid without significant shaking relative to the fixed unit 110. moves to .

When the extra blade unit 150 slides along the inner rail 115 like this and is located at the second point (P2), the shortest distance from the cutting blade (B) to the bottom of the comb teeth (159) at this point is the second height ( H2) is achieved.

If hair cutting is performed in this state, the length remaining from the cutting from the scalp to the tip of the hair forms a second length. Here, the second length is the same as the second height (H2) as described above with respect to the first point (P1), and the second height (H2) also has the cutting blade (B) as described above. 159) When located as close to the top as possible, it may be equal to the length corresponding to the height (H2) of the comb teeth (159) at the second point (P2).

As a result, when the blade unit 150 is located at the second point P2, the second length, which is the length from the scalp to the tip of the hair, corresponds to the height H2 of the comb teeth 159 at the second point P2. This may be the way to go.

Here, the length corresponding to the height (H1, H2) of the comb teeth 159 at the first point (P1) and the second point (P2) is the same as the height of the comb teeth 159 at the corresponding point, as well as the comb teeth ( 159) refers to the length corresponding to the height and within a certain deviation range.

The blade unit 150 can be moved to another point through the above-described method. In this case, the length of the hair remaining after being cut at the corresponding point may be equal to the length corresponding to the height of the comb teeth 159 at the corresponding point, as described above.

Specifically, the extra blade unit 150 will be operated to move along the sliding direction (S) and be fixed at points where the heights of the comb teeth 159 at those points are 3 mm, 6 mm, 9 mm, 12 mm, 15 mm, 18 mm, and 21 mm, respectively. It may be possible. According to this configuration, there is no need to provide seven separate standard clipper jacks having the heights of the comb teeth 159 of 3 mm, 6 mm, 9 mm, 12 mm, 15 mm, 18 mm, and 21 mm, respectively.

Meanwhile, when the extra blade unit 150 moves all the way to the rear, the end of the sub-rail 175 comes into contact with the stopper 177. As a result, it is possible to prevent the extra blade unit 150 from moving excessively to the rear of the fixing unit 110 and unexpectedly falling out.

Hereinafter, an additional blade for a hair clipper capable of adjusting the hair cutting length according to another embodiment of the present invention will be described in detail with reference to FIGS. 7 and 8.

Figure 7 is an operational diagram of an extra blade 100' for a hair clipper capable of adjusting the hair cutting length according to another embodiment of the present invention.

The fixing pin 183 is located within the through hole 181.

The knob 185 is formed at the end of the fixing pin 183 located on the outside of the body 151.

The upper support piece 187 is installed on the fixing pin 183.

The lower support piece 189 is formed on the inner peripheral surface of the through hole 181.

The spring 191 is installed so that both ends are supported on the upper support piece 187 and the lower support piece 189, respectively.

The operating method of the extra blade 100' for a hair clipper configured as above is as follows.

First, when the blade unit 150 is located at the first point P1, the fixing pin 183 is inserted into the fixing groove 119 and locked by the elastic restoring force of the spring 191. By this, the extra blade unit 150 is firmly fixed to the fixing unit 110. In this state, the first length of the hair remaining after being cut is equal to the length corresponding to the height H1 of the comb teeth 159 at the first point P1, as described above with reference to FIGS. 5 and 6.

If hair cutting of a length different from the first length is required, the user may move the blade unit 150. To do this, the user first pulls the knob 185. As a result, the fixing pin 183 is separated from the fixing groove 119 and unlocked. In this unlocked state, the blade unit 150 can move to the second point P2 along the sliding direction S with respect to the fixed unit 110.

When the blade unit 150 reaches the second point (P2), the user can release the knob 185, whereby the fixing pin 183 receives the elastic restoring force of the spring 191 and returns to another fixing groove 119. ) can be locked. At this time, the second length of the hair remaining after being cut by the extra blade 100' for the hair clipper is also equal to the length corresponding to the height H2 of the comb teeth 159 at the second point P2.

Figure 8 is an operational diagram of an extra blade (100") for a hair clipper capable of adjusting the hair cutting length according to another embodiment of the present invention.

Referring to this drawing, the extra blade 100" for a hair clipper according to this embodiment has a structure in which the extra blade unit 150 moves by dial-type rotation.

Specifically, the fixing unit 110 may further include a rotating shaft 121, a circular chip 123, a fixing protrusion 125, an elastic protrusion 127, and a tooth 129.

The rotation axis 121 is installed on the side of the plate 111. Specifically, the rotation axis 121 is installed on the side of the plate 111 to face a direction perpendicular to the slide direction of the blade unit 150.

The circular chip 123 is rotatably installed on the rotation shaft 121.

A plurality of fixing protrusions 125 are arranged along the circumferential direction on the circumferential surface of the circular chip 123, respectively.

The elastic protrusion 127 is located on the side of the plate 111.

A plurality of teeth 129 are formed along the circumferential direction on the main surface of the circular chip 123 facing the elastic protrusion 127.

Meanwhile, the extra blade unit 150 includes a wing portion 193 and a fixing groove 195.

The wing portion 193 extends along the sliding direction (S) to the body 151.

A plurality of fixing grooves 195 are each concavely formed along the sliding direction (S) at the top of the wing portion 193. Specifically, the fixing groove 195 has a shape corresponding to the fixing protrusion 125 so as to engage with the fixing protrusion 125, respectively.

The operation method of the extra blade (100") for a hair clipper with adjustable hair cutting length configured as above is as follows.

First, when the extra blade unit 150 is located at the first point (P1), the elastic protrusion 127 comes into contact with the teeth 129 to provide a predetermined fixing force to the circular chip 123, thereby )'s rotation is slightly limited. In addition, since the rotation of the fixing protrusion 125, which is integral with the circular chip 123, is also restricted, the movement of the extra blade unit 150 is also restricted due to the configuration of the fixing groove 195 engaged with the fixing protrusion 125. In this way, when the blade unit 150 is fixed at the first point (P1), the first length of the hair remaining after being cut is equal to the height (H1) of the comb teeth 159 at the first point (P1) as described above. It is the same as the corresponding length.

If hair cutting of a length different from the first length is required, the user can move the extra blade unit 150 by turning the circular chip 123. In this case, due to the rotation of the circular chip 123, the elastic protrusion 127 taps the sawtooth 129, thereby generating a signal such as a click sound. Through these signals, the user can easily recognize the moving distance of the blade unit 150.

When the extra blade unit 150 moves along the sliding direction S and reaches the second point P2, the elastic protrusion 127 comes into contact with the teeth 129 again to provide a predetermined fixing force to the circular chip 123. And, as a result, the blade unit 150 is also fixed to the second point (P2). At this time, the second length of the hair remaining after being cut by the extra blade 100" for the hair clipper is also equal to the length corresponding to the height H2 of the comb teeth 159 at the second point P2.
