Abstract
Description
[Technical Field]
[0001] The present invention relates to a comb with a handle that ensures the rigidity of the handle and improves the ease of holding the handle. [Background technology]
[0002] Conventionally, combs have been used for styling hair, such as combing hair with multiple comb teeth protruding from the spine-like back of the comb, but professional comb users such as hairdressers and barbers also use combs to trim hair with clippers. Users who use combs for trimming hair with clippers are often seen in Europe and other places, and combs with a structure suitable for trimming hair are generally called clipper combs.
[0003] Patent Document 1 below discloses an example of a comb used for trimming hair with clippers. Figures 7 and 8 of Patent Document 1 show an example of a comb being used for trimming hair with clippers. The comb is placed against the scalp at areas of the head where hair is to be trimmed, such as the neckline or temporal region, and the comb is moved from bottom to top to comb the hair with multiple teeth, ensuring that hair protrudes from between the teeth. The hair protruding from between the teeth is then trimmed with the clippers, thereby trimming the hair. In this process, the clippers are brought into contact with the multiple teeth and moved while sliding over these teeth, ensuring that the length of hair remaining after being cut with the clippers is uniform.
[0004] Other examples of combs suitable for trimming, known as clipper combs, include the type of comb with a handle (handled comb) shown in Patent Documents 2 and 3 below. Such handled combs have a handle that is specifically for gripping, so that trimming work with clippers can be performed while holding the handle, making them advantageous in that the comb can be easily maintained in a stable position even when the clippers are moved during trimming work. The combs shown in Patent Documents 2 and 3 were created by the same inventor as the present invention. [Prior art documents] [Patent documents]
[0005] [Patent Document 1] Special Publication No. 2013-539702 [Patent Document 2] Design Registration No. 1566291 [Patent Document 3] Design Registration No. 1648702 Summary of the Invention [Problem to be solved by the invention]
[0006] When using clippers with a comb to trim hair, the length of the hair remaining after trimming depends on the thickness of the comb, and it is physically impossible to trim the hair so that it is shorter than the thickness of the comb. Therefore, in order to shorten the trimmed length of the hair, it is necessary to reduce the thickness of the comb itself.
[0007] However, reducing the thickness of the comb itself reduces the rigidity of the comb. In particular, in the case of the handle combs shown in Patent Documents 2 and 3, the thickness of the handle also becomes thin and flimsy, reducing the rigidity of the handle, making the comb difficult to hold and making it difficult to stably perform hair cutting work using clippers.
[0008] Furthermore, with handled combs, there are various ways of holding the handle depending on the user. For example, some users hold the handle by pinching the contours of the upper and lower edges of the handle (for example, the periphery near the back of the comb) with their fingertips. For users who pinch the contours of the handle in this way, a thinner handle creates the problem of making it difficult to hold the comb in a stable position. Another way of holding the handle is by placing the thumb and index finger on the front and back surfaces of the handle. While there are various ways to hold the handle of a handled comb, it is common to place the rear end of the handle in the palm of the hand to stabilize the comb, regardless of the grip.
[0009] In response to the above-mentioned problem, it is conceivable to increase the thickness of only the handle portion rather than uniformly thinning the thickness of the entire comb, thereby ensuring the rigidity of the handle portion and preventing a decrease in the ease of gripping the handle portion. However, if only the handle portion is thickened in this way, the handle portion alone will become heavy, and the center of gravity of the comb as a whole will be closer to the handle, resulting in an imbalance in the center of gravity of the comb and making it difficult for users to use.
[0010] To provide a comb with a handle that is suitable for cutting hair with clippers, and that can prevent deterioration of the balance of the entire comb while ensuring the rigidity of the handle and also ensures good gripping of the handle, even when the hair can be cut short with clippers. [Means for solving the problem]
[0011] In order to solve the above problems, the handled comb of the present invention is a handled comb comprising a spine-shaped comb back, multiple comb teeth protruding from the comb back, and a long, plate-shaped handle extending from the rear end of the comb back, characterized in that the handle has thick frame portions formed on each of the opposing edges within the surrounding outline that are thicker than the comb back, and the handle is designed to become thinner toward the rear end of the handle.
[0012] In the present invention, thick frame sections are formed on both edges of the handle that face each other in the width direction, with the thick frame sections being thicker than the comb back section. This allows the thick frame sections to function like ribs, ensuring the required rigidity of the handle. Furthermore, by forming such thick frame sections, the area that the user's fingertips touch when gripping the handle is the thicker portion, ensuring the required contact area for the fingertips and making the handle easier to grip. It is preferable to form such thick frame sections in the repaired handle contour, including the area closer to the comb back section, which is the area that is easiest to grip when holding the handle.
[0013] Furthermore, the thickness of the handle gradually decreases toward the rear end, which suppresses an increase in the weight of the handle compared to when the thickness of the entire handle is uniformly increased. As a result, the center of gravity of the comb is prevented from being too close to the handle, preventing the weight distribution balance of the entire comb from becoming unbalanced, and maintaining the ease of use of the comb.
[0014] Furthermore, the comb with handle according to the present invention is characterized in that a border portion of a predetermined width is formed on the inner periphery of the thick frame portion, and the border portion includes a slope that is inclined so that the thickness dimension becomes thinner from the peripheral edge side of the handle toward the inside.
[0015] In the present invention, the thick frame portion is formed with a rim around the inner periphery of the thick frame portion formed around the periphery of the handle, and the rim portion is sloped so that its thickness decreases inward from the rim. Therefore, when a user holds the handle by pinching the front and back surfaces of the handle between their thumb and index finger, the rim acts as a guide for the fingers and also increases the grip of the fingers, improving the grip performance of the handle compared to conventional methods. In particular, when the user is a hairdresser, there are many situations where various liquid agents adhere to the fingers and make the fingertips slippery when holding the comb, so the rim acts as a slip prevention element, ensuring good usability.
[0016] The comb with handle according to the present invention is characterized in that the border portions of the thick frame portions formed on the opposing peripheries are spaced apart by a length that is at least 1 / 3 of the width dimension of the handle at the point where the border portions are spaced apart, and the handle surface at the point where the border portions of the thick frame portions are spaced apart is flat.
[0017] In this invention, the bordered portions of opposing edges are separated by a length equal to or greater than one-third of the width of the handle, and the handle surface between the bordered portions is flat, so that users who grip the handle by placing their fingertips against the handle surface have a flat surface on which to place their fingertips. Furthermore, because such a surface is sandwiched between the sloping bordered portions, the fingertips placed on the flat surface are supported or guided by the bordered portions on both sides, improving the ease of placement of the fingertips and the stability of the fingertips placed on the handle surface, thereby ensuring a good grip of the handle. In this invention, "having a flat handle surface" means that the basic configuration of the handle surface is flat. For example, even if holes are drilled in a flat handle surface, the handle surface remains flat. Furthermore, even if letters or patterns are formed on the flat handle surface so that they are raised, the handle surface remains flat.
[0018] Furthermore, by ensuring that the distance between opposing edging sections is at least one-third of the width of the handle, the thick frame section including the edging section does not become larger than necessary, thereby suppressing an increase in the weight of the handle and maintaining a good balance of the center of gravity of the comb. Note that the upper limit of the distance between edging sections is the length that allows each edging section to maintain its slope.
[0019] The handle comb of the present invention is characterized in that, within the peripheral contour of the handle, in the area where the thick frame portion is formed, concavely curved recessed portions and convexly curved protruding portions are formed, and the concave portions are located closer to the back of the comb than the protruding portions.
[0020] In the present invention, thick frame portions are formed at the concave and convex portions of the outline, and the concave portions are located closer to the back of the comb than the convex portions. Therefore, for a user who holds the comb by grasping the outline of the handle, the fingertips fit into the concave portions closer to the back of the comb, and the convex portions assist in positioning the fingers that fit into the concave portions. Furthermore, the thick frame portions ensure that these convex and concave portions have a wide contact area for the fingertips, making it even easier to grip the outline of the handle.
[0021] The comb with handle according to the present invention is characterized in that the edging portion is formed along the curved shapes of the concave and convex portions.
[0022] In the present invention, the edging of the thick frame is curved to follow the curved concave and convex parts of the peripheral contour, so that the edging matches the contour of the peripheral contour so that it matches the contour, ensuring a favorable grip when the user holds the handle with one finger (e.g., index finger) against the contour of the handle and another finger (e.g., thumb) against the surface of the handle. In other words, because the contour of the handle and the edging around the surface of the handle have similar contours, even when one finger (e.g., index finger) is placed against a concave part of the peripheral contour, the edging has a similar contour, ensuring a surface area of a predetermined width, and allowing the other finger to be placed nicely on the surface of the handle, resulting in a favorable grip of the handle.
[0023] The comb with handle according to the present invention is characterized in that the thick frame portion and the edging portion are formed around the entire periphery of the contour of the handle.
[0024] In the present invention, the thick frame and edging are formed around the entire circumference of the handle, which improves the overall rigidity of the handle, making it easier to hold the comb when using clippers for trimming, and therefore allowing the clippers to be moved stably, making it easier to perform trimming work. In particular, regardless of how the user holds the handle, the rear end of the handle rests against the palm of the hand, which places a certain amount of pressure on the rear end of the handle. However, by forming the thick frame and edging around the entire circumference, the rear end of the handle is able to withstand the above-mentioned pressure, providing the user with a firm and stable grip. [Effects of the Invention]
[0025] In the present invention, thick frame portions are formed at required locations on the handle outline, which ensures the rigidity of the handle and also provides a sufficient area for fingers to place when pinching and gripping the handle outline, providing good gripping ability for the handle.In addition, since the handle becomes thinner towards the rear end, even if thick frame portions are formed, an increase in the weight of the handle can be suppressed, and deterioration of the weight balance of the entire comb can be prevented. Furthermore, in the present invention, a rimmed portion including a slope is formed on the inner periphery of the thick frame portion, so that when the surface of the handle is grasped with the fingertips, the rimmed portion with a slope acts as a guide to guide the fingers, making it easy to position the fingers that are about to grasp, and once the handle is grasped with the fingers, the rimmed portion also increases the grip of the fingers, improving the grip performance of the handle and thereby ensuring good grip of the handle.
[0026] Furthermore, in the present invention, the opposing edging portions are separated by a length that is at least one-third of the width dimension of the handle, and a flat surface is formed in the space between them.Therefore, when the fingertips are placed on the surface of the handle and the comb is held in place, the fingertips can be placed stably on the flat surface, and the thick frame portion including the edging portions does not become larger than necessary.This prevents the handle from becoming too heavy and avoids the weight balance of the entire comb being disrupted.
[0027] Furthermore, in the present invention, thick frame portions are formed at the concave and convex portions of the handle outline, and the concave portions are positioned closer to the back of the comb than the convex portions. Therefore, when holding the handle with your fingers placed against the handle outline, the convex portions can guide your fingertips so that they fit into the concave portions closer to the back of the comb, and once your fingertips are in the concave portions, the convex portions can assist in preventing your fingers from moving, thereby further improving the grip when holding the handle with your fingers placed against the handle outline.
[0028] In the present invention, the edging portion of the thick frame is curved along the uneven parts of the peripheral contour of the handle, so that the edging portion is linked to the unevenness of the peripheral contour and can be made into a matching shape, thereby improving the grip on the peripheral contour of the handle and the surface of the handle. Furthermore, in the present invention, a thick frame and a edging portion are formed around the entire contour of the handle, thereby improving the overall rigidity of the handle and providing the user with a firm grip when holding the handle.

DETAILED DESCRIPTION OF THE INVENTION [Example]
[0030] 1 to 10 show a handled comb 1 according to a first embodiment of the present invention. The handled comb 1 of the present invention is a type of comb known as a clipper comb, and is integrally molded from synthetic resin. The general configuration of the comb 1 is as follows: a plurality of comb teeth 3 protrude perpendicular to the longitudinal direction of the comb back 2, which forms the backbone-like main body of the comb; a first comb protection part 4 and a second comb protection part 5 extend parallel to the protruding direction of each comb tooth 3 from the leading end 2a (one end) and rear end 2b (the other end) of the comb back 2 in the longitudinal direction, sandwiching the plurality of comb teeth 3, thereby protecting the comb teeth 3; and a handle 6 extends from the rear end 2b of the comb back 2 along the longitudinal direction of the comb back 2.
[0031] 1 is the direction along the longitudinal direction of the comb back 2 extending like a spine, the Y axis perpendicular to the X axis is the direction along the protruding direction of the comb teeth 3 (which also corresponds to the width direction of the handle 6), and the Z axis perpendicular to the X axis and Y axis is the direction along the thickness direction of the comb 1, the comb back 2, and the handle 6 (these directions are the same in other figures). In FIG. 1 etc., the arrow indicating the X axis points from the rear end side 2b to the front end side 2a of the comb back 2, the arrow indicating the Y axis points in the direction in which the comb teeth 3 protrude from the comb back 2, and the arrow indicating the Z axis points from the back side to the front side of the comb 1 (the directions of these arrows are the same in other figures).
[0032] The handled comb 1 of the first embodiment has a thinner comb portion (the portion consisting of the comb back portion 2 and the multiple comb teeth 3, etc.) than a typical comb, so that it can be used to trim hair short when using clippers. As a specific example, the thickness T1 of the comb back portion 2 of the first embodiment (see FIGS. 6 and 7) is set to about 2 mm.
[0033] The comb back portion 2 has a plurality of through-holes 8 formed therein, penetrating along the Z-axis direction from its front surface 2e to its opposite back surface 2f. Each of these through-holes 8 is elliptical and linearly arranged at predetermined intervals along the X-axis direction (see Figures 1, 3, 5, etc.). As shown in Figure 1, etc., the comb 1 has a plurality of comb teeth 3 protruding from the inner surface 2d opposite the back surface 2c of the comb back portion 2, between the first comb protection portion 4 and the second comb protection portion 5. When viewed as a whole, these multiple comb teeth 3 are arranged in a continuous plane, and the plane where the multiple comb teeth 3 are arranged in a continuous line is oriented parallel to the XY plane defined by the X-axis and Y-axis.
[0034] The handle 6, which extends from the rear end 2b of the comb back portion 2 along the X-axis direction, has an elongated, long plate-like shape. As shown in Fig. 4, the handle 6 is connected to the rear end 2b of the comb back portion 2 and also to the second comb protection portion 5, and the width dimension (in the Y-axis direction) of the handle tip 6a, which is connected to the comb back portion 2 and the second comb protection portion 5, is the widest. In this embodiment, the second comb protection portion 5 is the area surrounded by a rectangular dashed line in Fig. 4.
[0035] 2, 5, etc., the handle 6 has a total of three through-holes, the first through third handle through-holes 7a through 7c, which penetrate from the handle front surface 6e to the handle back surface 6f. The first through-hole 7a, which is formed closest to the handle rear end 6b, has a shape that resembles a combination of a semicircle and a pentagon, while the second through-hole 7b and the third through-hole 7c have heart-shaped shapes. Each of the handle through-holes 7a through 7c has a significantly larger hole opening rate than the oval-shaped through-hole 8 formed in the comb back portion 2. Therefore, the weight of the handle 6 is reduced by forming these first through third handle through-holes 7a through 7c.
[0036] Furthermore, as shown in Figure 4, etc., the handle 6 has multiple concave portions 30a, 30b, 32a to 32d and convex portions 31a, 31b, 33a to 33d formed on its peripheral contour so as to have a curved shape when viewed from the front (for example, from the viewing direction shown in Figures 3 and 4).
[0037] Specifically, the handle 6 has, on its peripheral contour, a first back-side concave portion 30a, a first back-side convex portion 31a, a second back-side concave portion 30b, and a second back-side convex portion 31b formed in that order from the handle tip 6a side on the back-side edge 6c on the side corresponding to the back surface of the comb back portion 2 (the bottom side, the side that is the lower side in Figures 3 and 4), and further, on the tooth-side edge 6d on the side corresponding to the orientation of the tooth tips of each comb tooth 3 (the side that is the upper side in Figures 3 and 4), a first tooth-side concave portion 32a, a first tooth-side convex portion 33a, a second tooth-side concave portion 32b, a second tooth-side convex portion 33b, a third tooth-side concave portion 32c, a third tooth-side convex portion 33c, a fourth tooth-side concave portion 32d, and a fourth tooth-side convex portion 33d formed in that order from the handle tip 6a side.
[0038] 4, of the dorsal recesses 30a, 30b formed on the dorsal periphery 6c of the handle 6, the first dorsal recess 30a closer to the comb dorsal portion 2 has a shorter length in the direction along the extension of the handle 6 (the direction along the X-axis) than the second dorsal recess 30b, and is set to a dimension that corresponds to a person's fingertip. This makes it easier for a user who grips the outline of the handle 6 to place their finger on the first dorsal recess 30a.
[0039] Furthermore, among the tooth side recessed portions 32a to 32d formed on the tooth side peripheral edge 6d of the handle 6, the fourth tooth side recessed portion 32d near the rear end 6b of the handle has a longer length dimension in the direction along the extension direction of the handle 6 (direction along the X-axis) than the other first tooth side recessed portions 32a to third tooth side recessed portions 32c, and the remaining first tooth side recessed portion 32a to third tooth side recessed portions 32c, like the above-mentioned first back side recessed portion 30a, are set to length dimensions corresponding to a person's fingertips, making it easier for the user to place their fingers on these tooth side recessed portions 32a to 32c.
[0040] The tooth side peripheral edge 6d of the handle 6 has three tooth side recesses 32a to 32c for easy finger placement. This is because when the contour of the handle 6 is grasped, the user's index finger is usually placed on the tooth side peripheral edge 6d side, and the index finger is easier to move than the thumb. Accordingly, the contour locations where the fingers are placed when grasping the handle 6 vary greatly from user to user, so this allows the handle to be adapted to various holding styles of users.
[0041] In addition, the first dorsal recessed portion 30a formed on the dorsal periphery 6c and the first tooth-side recessed portion 32a formed on the tooth-side periphery 6d are slightly offset in position in the X-axis direction (the first tooth-side recessed portion 32a is formed slightly closer to the comb dorsal portion 2 than the first dorsal recessed portion 30a). This is because, when the user grasps the contour of the handle 6 with their fingers, the positions of the thumb placed on the dorsal periphery 6c and the index finger placed on the tooth-side periphery 6d will be slightly different in the X-axis direction.
[0042] Furthermore, since the number of concave portions 30a-30b, 32a-32d and convex portions 31a-31b, 33a-33d differs between the back side peripheral edge 6c and the tooth side peripheral edge 6d of the handle 6, the positions in the X-axis direction of the first back side convex portion 31a on the back side peripheral edge 6c, which is closest to the comb back portion 2, and the first tooth side convex portion 33a on the tooth side peripheral edge 6d are also misaligned.
[0043] That is, because the tooth-side peripheral edge 6d of the handle has more convex and concave portions than the dorsal peripheral edge 6c, the first tooth-side convex portion 33a of the tooth-side peripheral edge 6d is formed in a portion closer to the comb dorsal portion 2 in the X-axis direction than the first dorsal convex portion 31a of the dorsal peripheral edge 6c, and the first dorsal convex portion 31a of the dorsal peripheral edge 6c is formed in a portion closer to the second tooth-side concave portion 32b of the tooth-side peripheral edge 6d. By arranging the convex portions 31a-31b and 33a-33d in such positions, when a user places their fingers on the peripheral contour of the handle 6, it becomes easier to guide their fingertips into the above-mentioned concave portions 30a-30b and 32a-32d and to stably maintain (hold) their fingertips in the concave portions 30a-30b and 32a-32d.
[0044] Furthermore, as a feature of the present invention, the handle 6 has thick frame portions 10, 20 formed on the back side peripheral edge 6c and the tooth side peripheral edge 6d, which are opposed to each other along the Y-axis direction within the peripheral outline, and which have a thickness dimension greater than the thickness dimension T1 of the comb back portion 2 (see Figures 6 and 7).
[0045] Figure 9(a) is a schematic cross-sectional view showing the handle 6 cut along line A1-A1 (a line parallel to the Y-axis direction) that passes through the deepest part of the first dorsal recessed portion 30a of the dorsal rim 6c in Figure 4. The dorsal rim 6c, which is the lower side in Figure 9(a), has a dorsal thick frame portion 10 (first thick frame portion), and the tooth side edge 6d, which is the upper side in Figure 9(a), has a tooth side thick frame portion 20 (second thick frame portion).
[0046] The thickness of the handle 6 is greatest in the range from the cut surface in Figure 9(a) (the area indicated by line A1-A1 in Figure 4) to the first dorsal convex area 31a, and the thickness dimension T2 at the area shown in Figure 9(a) can be set to approximately 6.2 mm, for example.
[0047] The back thick frame portion 10 has a thickness dimension T2 in the direction along the Z axis (thickness direction), from one end 10a of the back frame on the side of the front handle 6e to the other end 10b of the back frame on the side of the back handle 6f. The one end 10a and the other end 10b of the back frame, which are both ends in the thickness direction, are chamfered to have rounded corners, and the surface corresponding to the back periphery 6c except for the areas near these ends is flat.
[0048] Furthermore, the back-side thick frame portion 10 forms a back-side first edging portion 11 on the inner periphery on the handle front surface 6e side, and forms a back-side second edging portion 12 on the inner periphery on the handle back surface 6f side. Specifically, the back-side first edging portion 11 is formed from one end 10a of the back frame, which is one end side in the thickness direction (Z-axis direction), toward the handle front surface 6e, which is inside the handle 6, and the back-side second edging portion 12 is formed from the other end 10b of the back frame, which is the other end side in the thickness direction (Z-axis direction), toward the handle back surface 6f, which is inside the handle 6.
[0049] As shown in Figures 3 and 4, the first back edge portion 11 formed on the front side 6e of the handle has a predetermined width (meaning the width dimension along the Y-axis direction) on the inner side of the back thick frame portion 10, and has an edge shape that follows the curved shapes of the concave portions 30a, 30b and convex portions 31a, 31b of the back edge 6c of the handle 6 described above.
[0050] For example, the dorsal first edging portion 11 at a location corresponding to the first dorsal recessed portion 30a has an edge shape that is convexly curved inward of the handle 6 along the concavely curved shape of the dorsal peripheral edge 6c of the first dorsal recessed portion 30a, and the dorsal first edging portion 11 at a location corresponding to the first dorsal convex portion 31a has an edge shape that is convexly curved outward of the handle 6 along the convexly curved shape of the dorsal peripheral edge 6c of the first dorsal convex portion 31a. The configuration relating to the shape of the predetermined width of the dorsal first edging portion 11 is also the same for the dorsal second edging portion 21 formed on the handle back surface 6f side.
[0051] In addition, the predetermined width dimension (width dimension along the Y-axis direction) of the back first edging portion 11 at the location shown in Figure 9(a) (the location shown by line A1-A1 in Figure 4) can be set to approximately 7 mm, as an example.
[0052] 4 and 5, for example, the dorsal second edging portion 12 at the location corresponding to the first dorsal concave portion 30a, like the above-mentioned dorsal first edging portion 11, has a shape that is convexly curved inward toward the handle 6 along the concavely curved shape at the dorsal periphery 6c of the first dorsal concave portion 30a, and the dorsal second edging portion 12 at the location corresponding to the first dorsal convex portion 31a has a shape that is convexly curved outward toward the handle 6 along the convexly curved shape at the dorsal periphery 6c of the first dorsal convex portion 31a.
[0053] 9(a)(b), the dorsal first trimmed portion 11 has a shape including a slope that is inclined so that the thickness (dimension along the Z-axis direction) becomes thinner from the dorsal frame one end 10a of the dorsal peripheral edge 6c, which is on the peripheral side of the handle 6, to the handle front surface 6e, which is on the inside of the handle 6. That is, the dorsal first trimmed portion 11 has a slope that is inclined so that the thickness is greatest on the side of the dorsal frame one end 10a and is smallest at the dorsal first edge end 11a, which is on the inside of the handle 6. Furthermore, the slope of the dorsal first trimmed portion 11 is not flat, but is a curved surface that is slightly convex and bulges out.
[0054] 9(a), the dorsal second edging portion 12 has a shape that is bilaterally symmetrical (flipped left and right) to the above-described dorsal first edging portion 11, and has a shape that includes a slope that is inclined so that the thickness dimension (dimension along the Z-axis direction) becomes thinner from the dorsal frame other end 10b of the dorsal peripheral edge 6c, which is on the peripheral side of the handle 6, to the handle back surface 6f, which is on the inside of the handle 6. Therefore, the dorsal second edging portion 12 also has a slope that is inclined so that the thickness dimension is greatest at the dorsal frame other end 10b side and is smallest at the dorsal second edge end 12a, which is on the most inside of the handle 6, and the slope of the dorsal second edging portion 12 also has a curved surface that is slightly convex and bulges out.
[0055] On the other hand, in Figure 9(a), the upper tooth-side thick frame portion 20 is configured as a vertically symmetrical (upside-down) version of the above-mentioned back-side thick frame portion 10, but the shape itself has a slightly different angle of the slope.
[0056] Specifically, the tooth side thick frame portion 20 has a thickness dimension T2, which is the length along the Z-axis direction (thickness direction) from one end 20a of the tooth side frame on the side of the handle front 6e to the other end 20b of the tooth side frame on the side of the handle back 6f, and the tooth side frame one end 20a and the tooth side frame other end 20b, which are both ends in the thickness direction, are chamfered to have rounded corners, and the surface corresponding to the tooth side peripheral edge 6d except for those near both ends is flat, and this configuration is the same as that of the back side thick frame portion 10 described above.
[0057] The tooth-side thick frame portion 20 also has a tooth-side first edging portion 21 formed on the inner periphery on the handle front surface 6e side, and a tooth-side second edging portion 22 formed on the inner periphery on the handle back surface 6f side. Specifically, the tooth-side first edging portion 21 is formed from one end 20a of the tooth-side frame toward the handle front surface 6e, which is on the inside of the handle 6, and the tooth-side second edging portion 22 is formed from the other end 20b of the tooth-side frame toward the handle back surface 6f, which is on the inside of the handle 6.
[0058] As shown in Figures 3-5 and other figures, the tooth-side first trimmed portion 21 formed on the handle front surface 6e has a predetermined width (meaning the width dimension along the Y-axis direction) and has an edge shape that follows the curved shapes of the recessed portions 32a-32d and the protruding portions 33a-33d of the tooth-side peripheral edge 6d of the handle 6. The configuration relating to the predetermined width shape of the tooth-side first trimmed portion 21 is also the same for the tooth-side second trimmed portion 22 formed on the handle back surface 6f. Note that the predetermined width (width dimension along the Y-axis) of the tooth-side first trimmed portion 21 at the location shown in Figure 9(a) (the location indicated by line A1-A1 in Figure 4) may be set to, for example, approximately 5.8 mm, which is smaller than the predetermined width (for example, approximately 7 mm) of the back-side first trimmed portion 11 at the location shown in Figure 9(a) described above.
[0059] The tooth-side first trimmed portion 21 has a shape including a slope that is inclined so that the thickness dimension (dimension along the Z-axis direction) becomes thinner from the tooth-side frame one end 20a of the tooth-side peripheral edge 6d, which is on the peripheral side of the handle 6, to the handle front surface 6e, which is on the inside of the handle 6, and such a slope is a curved surface that curves slightly convexly and bulges out. As described above, in the location shown in Figure 9(a), the predetermined width dimension of the tooth-side first trimmed portion 21 is smaller than the predetermined width of the back-side first trimmed portion 11, and therefore the angle of the slope of the tooth-side first trimmed portion 21 with respect to the handle front surface 6e is larger than the slope of the back-side first trimmed portion 11.
[0060] In addition, in Figure 9(a), the tooth side second edge portion 22 has a shape that is a left-right symmetrical (left-right reversed) version of the tooth side first edge portion 21, and has a shape that includes a slope that is inclined so that the thickness dimension (dimension along the Z-axis direction) becomes thinner from the other end 20b of the tooth side frame of the tooth side peripheral edge 6d, which is on the peripheral side of the handle 6, to the handle back surface 6f, which is on the inside of the handle 6, and the slope is a curved surface that is slightly curved and bulges out in a convex manner.
[0061] Furthermore, as described above, the back side thick frame portion 10 and tooth side thick frame portion 20 shown in Figure 9(a) are formed on the opposing edges of the back side peripheral edge 6c and tooth side peripheral edge 6d at the most recessed portion (the portion indicated by line A1-A1) of the first back side recessed portion 30a in Figure 4, but the back side first edging portion 11 of this back side thick frame portion 10 and the tooth side first edging portion 21 of the tooth side thick frame portion 20 are spaced apart by a width dimension H2 (corresponding to the dimension from the back side first edge end 11a to the tooth side first edge end 21a in Figure 9(a)).
[0062] The handle front surface 6e corresponding to the range of dimensions from the first back edge 11a to the first tooth side edge 21a is made flat, thereby ensuring a flat surface for placing fingers when gripping the handle 6 with fingers placed on the handle front surface 6e. To ensure an area for placing fingers on the handle front surface 6e, the width dimension H2, which is the dimension from the first back edge 11a to the first tooth side edge 21a, is set to be at least one-third of the width dimension H1 of the handle 6 at the point shown in Figure 9(a) (the point indicated by the A1-A1 line). As a specific example, it is assumed that the width dimension H1 is approximately 24 mm and the width dimension H2 is approximately 11 mm, but of course these values are not limited to these values.
[0063] The above-described configuration of the spacing between the first dorsal edge 11 and the first tooth-side edge 21 on the handle front surface 6e is also similar to the configuration of the spacing between the second dorsal edge 12 and the second tooth-side edge 22 on the handle back surface 6f. That is, the second dorsal edge 12 of the thick dorsal frame portion 10 and the second tooth-side edge 22 of the thick tooth-side frame portion 20 are spaced apart by a width H2 (corresponding to the dimension from the second dorsal edge 12a to the second tooth-side edge 22a in FIG. 9(a)), and the handle back surface 6f corresponding to the dimension range from the second dorsal edge 12a to the second tooth-side edge 22a is made flat. Similarly, the width H2 from the second dorsal edge 12a to the second tooth-side edge 22a is at least one-third of the width H1 of the handle 6.
[0064] 9(b) is a schematic cross-sectional view of the handle 6 taken along line A2-A2 (a line parallel to the Y-axis direction) passing through the area between the first handle through-hole 7a and the second handle through-hole 7b in FIG. 4. This FIG. 9(b) also shows the back-side thick frame portion 10 formed on the back-side periphery 6c and the tooth-side thick frame portion 20 formed on the tooth-side periphery 6d. However, as shown in FIGS. 6 and 7, the thickness of the handle 6 as a whole becomes thinner toward the handle rear end 6b. Therefore, the portion shown in FIG. 9(b) is closer to the handle rear end 6b than the portion shown in FIG. 9(a). Therefore, the thickness T4 of the handle 6 shown in FIG. 9(b) is thinner than the thickness T2 shown in FIG. 9(a). However, since the back side thick frame portion 10 and the tooth side thick frame portion 20 are present even at the location shown in Figure 9(b), the thickness dimension T4 is greater than the thickness dimension T3 of the handle 6 at the rear end 6b of the handle (see Figures 6 and 7) (T2>T4>T3).
[0065] As described above, the recessed portions 30a, 30b, 32a-32d and the raised portions 31a, 31b, 33a-33d are formed on the periphery 6c, 6d of the pattern 6, and therefore the width dimension of the pattern 6 and the spacing between the border portions may vary slightly depending on the location in the X-axis direction. For this reason, the width dimension of the pattern 6 is represented by H1 in Fig. 9(a), while the width dimension of the pattern 6 is represented by H1' in Fig. 9(b). Similarly, the width dimension covering the range of the pattern front 6e and the pattern back 6f in Fig. 9(a) is represented by H2, while the width dimension covering the range of the pattern front 6e and the pattern back 6f in Fig. 9(b) is represented by H2'.
[0066] 6, 7, 10, etc., the dorsal thick frame portion 10 of the dorsal rim 6c and the tooth side thick frame portion 20 of the tooth side rim 6d are formed to extend to the rear end 6b of the handle, where they are connected. By connecting the dorsal thick frame portion 10 and the tooth side thick frame portion 20 at the rear end 6b in this manner, a thick frame portion (the dorsal thick frame portion 10 and the tooth side thick frame portion 20) is formed around the entire periphery of the handle 6 (the periphery in a front view). Note that the dorsal thick frame portion 10 and the tooth side thick frame portion 20 are formed up to the handle tip 6a, but are formed so that the thickness decreases toward the handle tip 6a (see FIGS. 6, 7, 10, etc.).
[0067] As described above, the handled comb 1 of the present invention has thick frame portions (dorsal thick frame portion 10 and tooth side thick frame portion 20) of the above-mentioned configuration formed on each of the opposing edges (dorsal edge 6c, tooth side edge 6d) in the width direction (direction along the Y direction) of the handle 6 within the peripheral contour of the handle 6. Therefore, these thick frame portions with thick dimensions structurally function like ribs, and even if the handle 6 has a thin basic thickness dimension, the required rigidity can be ensured for the handle 6, and the handle 6 can be prevented from becoming heavy compared to when the thickness of the entire handle 6 is made uniformly large.
[0068] In particular, in terms of ensuring rigidity, in the case of the first embodiment, the thick frame portions 10, 20 and the edging portions 11, 12, 21, 22 are formed around the entire periphery of the outline of the handle 6, so that the entire periphery of the handle 6 has a ribbed configuration, and even if the inner thickness of the handle 6 is as thin as the back of the comb 2, the handle 6 can be made to have a solid and rigid feel overall. In addition, the overall thickness of the handle 6 is made thinner towards the rear end 6b of the handle, which also helps to reduce the weight of the handle 6 and prevents the center of gravity of the entire comb from becoming unbalanced.
[0069] Furthermore, the back side thick frame portion 10 and the tooth side thick frame portion 20 formed on the periphery 6c, 6d of the handle 6 are ensured to have a large thickness of thickness dimension T2 (see Figures 6 and 7), and therefore the surface of the periphery of the handle 6 on which such thick frame portions 10, 20 are formed is wider than that of a normal comb.As a result, for users who grip the periphery of the handle by pinching it with their fingers, there is a large area for their fingertips to rest on, making the handle 6 easier to hold.
[0070] Furthermore, the peripheral contour of the handle 6 is provided with concavely curved recessed portions 30a, 30b, 32a to 32d and convexly curved protruding portions 31a, 31b, 33a to 33d, and thick frame portions 10, 20 are formed in these concave and convex portions 30a to 33d. Therefore, when placing fingers on the periphery 6c, 6d of the handle 6, the fingertips are guided to the recessed portions 30a, etc. by the protruding portions 31a, etc., and once the fingertips are placed in the recessed portions 30a, etc., the position of the fingertips is stabilized by the concave curved shape and the protruding portions 31, etc., and this synergistic effect with the thick and thick frame portions 10, 20 contributes to making it easier to pinch the peripheral contour of the handle 6 with the fingers and grip it.
[0071] Furthermore, the thick frame portions 10, 20 formed on the handle 6 form edging portions 11, 12, 21, 22 that include slopes and have a predetermined width extending inward from the periphery 6c, 6d of the handle 6. For users who grip the handle by placing their fingers on the surface of the handle 6, these edging portions 11, 12, 21, 22 act as guides to guide the fingertips to the surface of the handle 6, and once the fingers are placed on the surface of the handle 6, these edging portions 11, 12, 21, 22 increase the grip of the fingers, thereby improving the grip of the handle.
[0072] Furthermore, as shown in Figure 9(a) etc., the distance between the edging parts 11, 21 that face each other on the handle front 6e and the edging parts 12, 22 that face each other on the handle back 6f ensures a width dimension H2 that is at least 1 / 3 (one-third) of the width dimension H1 of the handle 6, and the handle surface (handle front 6e and handle back 6f) within this width dimension H2 is made flat enough to easily press your fingers against, ensuring a flat area sufficient for your fingertips to rest against, and increasing stability when holding the handle 6 between your fingers placed against the handle surface, ensuring good grip of the handle 6.
[0073] The handled comb 1 according to the first embodiment is not limited to the above-described configuration, and various modifications are possible. For example, the thick frame portions 10, 20 may be formed only at required locations rather than around the entire periphery of the handle 6.
[0074] Regarding the required locations, when holding the peripheral contour of the handle 6 between the fingers, the fingers often rest on the area of the handle 6 closer to the comb spine 2. Therefore, it is conceivable to form the thick frame portions 10, 20 only in the area of the periphery 6c, 6d of the handle 6 closer to the comb spine. As an example of the area closer to the comb spine, the area indicated by the length dimension L2 from the handle tip 6a to half (1 / 2) of the overall length dimension L1 (the dimension along the X-axis) of the entire handle 6 shown in Figures 6 and 7 can be defined as the area closer to the comb spine 2. Forming the thick frame portions 10, 20 only in such a limited area (for example, the area indicated by the length dimension L2 in Figures 6 and 7) has the advantage of minimizing the increase in weight of the handle 6 due to the thick frame portions 10, 20.
[0075] Furthermore, the thick frame portions 10, 20 may be formed so that the thickness increases only on the side of the front handle 6e or only on the side of the back handle 6f, rather than being formed so that the thickness increases on both sides of the front handle 6e and the back handle 6f, with the other side remaining flat.
[0076] In the case of such a modified example, either the handle front 6e or the handle back 6f can be made flat (planar), so that when using clippers to trim, if such a flat surface is placed against the scalp, the handle comb 1 can be easily fitted to the scalp, and the weight increase can be suppressed compared to when the thick frame portions 10, 20 are formed so that the thickness increases on both the handle front 6e and the handle back 6f. Note that if the thick frame portions 10, 20 are formed so that the thickness increases only on the handle front 6e side or only on the handle back 6f side, it is possible to provide the comb as a comb for right-handed or left-handed users.
[0077] Furthermore, when simplifying the specifications, it is possible to omit the recessed portions 30a, 30b, 32a to 32d and the protruding portions 31a, 31b, 33a to 33d formed on the peripheral contour of the handle 6.
[0078] Furthermore, if it is difficult to provide a spacing of width H2, H2' (length dimension that is at least 1 / 3 of width H1, H1') between opposing border portions 11 and 21 (or 12 and 22) as shown in Figures 9(a) and (b) because the width dimensions H1, H1' of pattern 6 are not large, it is possible to shorten width dimensions H2, H2' to less than 1 / 3 of width dimensions H1, H1', or even to configure border portions 11 and 21 (or 12 and 22) so that there is no spacing between them.
[0079] Furthermore, in cases where the widths H1, H1' of the handle 6 are not large but it is desired to ensure large widths H2, H2' that cover the range of the handle front 6e and handle back 6f, it is possible to omit forming the edging portions 11, 12, 20, 21 from the thick frame portions 10, 20. In such a configuration where the edging portions 11, 12, 20, 21 are omitted, the thick frame portions 10, 20 have a wall-like shape that surrounds the inside of the handle with the peripheries 6c, 6d of the handle 6, making it possible to maximize the range of the handle front 6e and handle back 6f. [Example]
[0080] 11 to 18 show a handled comb 50 according to a second embodiment of the present invention. The handled comb 50 according to the second embodiment is also a type of comb known as a clipper comb, but is thicker overall than the handled comb 1 according to the first embodiment. While the basic configuration is the same as that of the handled comb 1 according to the first embodiment, the thick back frame 60 and thick tooth side frame 70 formed on the peripheral contour of the handle 56 are limited to required areas, and are not formed in the area near the rear end 56b of the handle.
[0081] Specifically, the handled comb 50 of the second embodiment has multiple comb teeth 53 protruding in a direction perpendicular to the longitudinal direction of the comb back 52, a first comb protective portion 54 and a second comb protective portion 55 extending from the front end side 52a and the rear end side 52b in the longitudinal direction of the comb back 52, and a handle 56 extending from the rear end side 52b of the comb back 52. The thickness dimension T11 (see Figures 14 and 15) of the comb portion (the portion consisting of the comb back 52 and multiple comb teeth 53, etc.) of the handled comb 50 is larger than the thickness dimension T1 (see Figures 6 and 7) of the comb back 2 of the first embodiment, and a specific numerical example of the thickness dimension T11 is set to approximately 4 mm, which is twice the thickness dimension T1 of the first embodiment.
[0082] The comb back portion 52 has a plurality of elliptical through-holes 58 formed at equal intervals, penetrating along the Z-axis direction from its front surface 52e to its back surface 52f. Furthermore, the handle 56, which has an elongated, long plate-like shape overall, is connected to the rear end side 52b of the comb back portion 52 and the second comb protection portion 55, as shown in Figures 11-13, and its width dimension (in the direction along the Y-axis direction) is widest at the handle tip 56a, which is the side connected to the comb back portion 52 and the second comb protection portion 55. The handle 56 has a total of three through-holes, a first through third handle through-holes 57a to 57c, penetrating from the handle front surface 56e to the handle back surface 56f.
[0083] Furthermore, as shown in Figure 12 etc., within the peripheral outline of the handle 56, the dorsal periphery 56c forms, in order from the handle tip 56a side, a first dorsal concave portion 80a, a first dorsal convex portion 81a, a second dorsal concave portion 80b, and a second dorsal convex portion 81b, and the tooth side periphery 56d forms, in order from the handle tip 56a side, a first tooth side concave portion 82a, a first tooth side convex portion 83a, a second tooth side concave portion 82b, a second tooth side convex portion 83b, a third tooth side concave portion 82c, a third tooth side convex portion 83c, a fourth tooth side concave portion 82d, and a fourth tooth side convex portion 83d.
[0084] Furthermore, the handle 56 has thick frame portions 60, 70 formed on the back-side peripheral edge 56c and the tooth-side peripheral edge 56d, which face each other along the Y-axis direction within the peripheral outline, and which have a thickness T12 (see FIGS. 14 and 15) larger than the thickness T11 (see FIGS. 14 and 15) of the comb back portion 52. However, in the second embodiment, these thick frame portions 60, 70 do not extend to the handle rear end 56b.
[0085] Figure 17(a) is a schematic cross-sectional view showing the handle 56 cut along line B1-B1 (a line parallel to the Y-axis direction) that passes through the deepest part of the first dorsal recessed portion 80a of the dorsal periphery 56c in Figure 12. The dorsal thick frame portion 60 (first thick frame portion) is formed on the dorsal periphery 56c, which is the lower side in Figure 17(a), and the tooth side thick frame portion 70 (second thick frame portion) is formed on the tooth side periphery 56d, which is the upper side.
[0086] The back-side thick frame portion 60 has a thickness T12, which is the length along the Z-axis direction (thickness direction) from one end 60a of the back frame on the handle front surface 56e side to the other end 60b of the back frame on the handle back surface 56f side. In the comb according to the second embodiment, the thickness of the handle 56 is also greatest in the range from the cross section in Fig. 17(a) (the area indicated by line B1-B1 in Fig. 12) to the first back-side convex portion 81a.
[0087] As described above, the handled comb 50 according to the second embodiment has a larger overall thickness than the handled comb 1 according to the first embodiment, and therefore the thickness T12 is larger than the thickness T2 of the back thick frame portion 10 of the first embodiment shown in Fig. 9(a) (one example of the actual value of the thickness T12 is considered to be set to approximately 8.4 mm). Note that the back frame one end 60a and the back frame other end 60b, which are both ends in the thickness direction of the back thick frame portion 60, are each chamfered to round the corners, and the surface corresponding to the back periphery 56c except for the vicinity of these ends is flat.
[0088] The back-side thick frame portion 60 forms a first back-side edging portion 61 on the handle front surface 56e side on its inner periphery, and a second back-side edging portion 62 on the handle back surface 56f side. Specifically, the first back-side edging portion 61 is formed from one end 60a of the back frame, which is one end in the thickness direction of the handle 56, toward the handle front surface 56e, which is inside the handle 56, and the second back-side edging portion 62 is formed from the other end 60b of the back frame, which is the other end in the thickness direction of the handle 56, toward the handle back surface 56f, which is inside the handle 56.
[0089] The dorsal first edging portion 61 on the handle front surface 56e side has a border shape of a predetermined width (meaning the width dimension along the Y-axis direction) that follows the curved shapes of the recessed portions 80a, 80b and the protruding portions 81a, 81b of the dorsal periphery 56c of the handle 56. The dorsal first edging portion 61 has a shape that includes a slope (a curved slope that curves slightly convexly) that tapers in thickness (dimension along the Z-axis direction) from the dorsal frame end 60a of the dorsal periphery 56c, which is on the periphery side of the handle 56, to the handle front surface 56e, which is on the inside of the handle 56. The predetermined width (width dimension along the Y-axis direction) of the dorsal first edging portion 61 at the location shown in FIG. 17(a) (the location shown by line B1-B1 in FIG. 12) can be set to approximately 7.5 mm, for example.
[0090] In addition, in Figure 17(a), the second back edge portion 62 has a shape that is symmetrical (left-right reversed) of the above-mentioned first back edge portion 61, and has a shape that includes a slope (a curved slope that is slightly convexly curved and bulges) that is inclined so that the thickness dimension (dimension along the Z-axis direction) becomes thinner from the other end 60b of the back frame of the back edge 56c, which is on the peripheral side of the handle 56, to the handle back surface 56f, which is on the inside of the handle 56.
[0091] On the other hand, the tooth side thick frame portion 70, which is the upper side in Figure 17(a), has a shape that is vertically symmetrical (upside down) of the above-mentioned back side thick frame portion 60, and the length along the Z axis direction (thickness direction) from one end 70a of the tooth side frame on the side of the handle front surface 56e to the other end 70b of the tooth side frame on the side of the handle back surface 56f is the thickness dimension T12, and the tooth side frame one end 70a and the tooth side frame other end 70b, which are both ends in the thickness direction, are chamfered to round the corners, and the surface corresponding to the tooth side peripheral edge 56d except for those near both ends is flat.
[0092] The tooth-side thick frame portion 70 also has a tooth-side first edging portion 71 formed on its inner periphery on the handle front surface 56e side and a tooth-side second edging portion 72 formed on the handle back surface 56f side. Specifically, the tooth-side first edging portion 71 is formed with a predetermined width (meaning the width dimension along the Y-axis direction) from one end 70a of the tooth-side frame, which is one end in the thickness direction of the handle 56, toward the handle front surface 56e, which is inward of the handle 56, and the tooth-side second edging portion 72 is formed with a predetermined width from the other end 70b of the tooth-side frame, which is the other end in the thickness direction of the handle 56, toward the handle back surface 56f, which is inward of the handle 56. Note that the predetermined widths (width dimensions along the Y-axis direction) of the tooth-side first and second edging portions 71, 72 at the location shown in FIG. 17(a) (the location shown by line B1-B1 in FIG. 12) may be set to, for example, approximately 7.5 mm, similar to the above-described back-side first edging portion 61.
[0093] The tooth side first trimmed portion 71 has a shape that includes an inclined slope (a curved slope that bulges slightly convexly) that tapers in thickness (dimension along the Z-axis) from one tooth side frame end 70a of the tooth side peripheral edge 56d, which is on the peripheral side of the handle 56, to a handle front surface 56e inside the handle 56. The tooth side second trimmed portion 72 has a shape that is bilaterally symmetrical (left-right inverted) of the tooth side first trimmed portion 71 in Figure 17(a), and has a shape that includes an inclined slope (a curved slope that bulges slightly convexly) that tapers in thickness (dimension along the Z-axis) from the other tooth side frame end 70b of the tooth side peripheral edge 56d, which is on the peripheral side of the handle 56, to a handle back surface 56f inside the handle 56.
[0094] As described above, the back side thick frame portion 60 and tooth side thick frame portion 70 shown in Figure 17(a) are formed at the opposing back side periphery 56c and tooth side periphery 56d of the most recessed portion (the portion indicated by line B1-B1) of the first back side recessed portion 80a in Figure 12, and the back side first edging portion 61 of this back side thick frame portion 60 and the tooth side first edging portion 71 of the tooth side thick frame portion 70 are spaced apart by a width dimension H12 (corresponding to the dimension from the back side first edge end 61a to the tooth side first edge end 71a in Figure 17(a)).
[0095] The handle front surface 56e corresponding to the range of the width dimension H12 is made flat, which makes it easy to place and press the fingers against the handle front surface 56e when gripping the handle. To ensure an area for placing the fingers on the handle front surface 56e, the width dimension H12 is set to a length that is at least one-third of the width dimension H11 of the handle 56 at the location shown in Figure 17(a). As a specific example, it is envisioned that the width dimension H11 is set to approximately 26 mm and the width dimension H12 is set to approximately 11.5 mm, but of course these values are not limited to these values.
[0096] The configuration related to this width dimension H12 is also similar to the configuration related to the distance between the back-side second edging portion 62 and the tooth-side second edging portion 72 on the handle back surface 56f. That is, the back-side second edging portion 62 of the back-side thick frame portion 60 and the tooth-side second edging portion 72 of the tooth-side thick frame portion 70 are spaced apart by the length of the width dimension H12, and the handle back surface 56f corresponding to this width dimension H12 is also flat.
[0097] 17(b) is a schematic cross-sectional view showing the surface of the handle 56 cut along the line B2-B2 (a line parallel to the Y-axis direction) that passes through the point between the first handle through-hole 57a and the second handle through-hole 57b in Fig. 12. In the handled comb 50 according to the second embodiment, the back-side thick frame portion 60 and the tooth-side thick frame portion 70 are not formed near the rear handle end 56b, and therefore the back-side thick frame portion 60 and the tooth-side thick frame portion 70 are not present in the area along the line B2-B2.
[0098] 17(b), the handle 56 has a rectangular cross section with a constant thickness T14 between the handle front surface 56e and the handle back surface 56f from the lower back-side edge 56c to the upper tooth-side edge 56d. However, in the handled comb 50, the thickness of the handle 56 as a whole becomes thinner toward the handle rear end 56b as shown in FIGS. 14 and 15. Therefore, the thickness T14 at the point shown in FIG. 17(b) (the point along the B2-B2 line) is slightly larger than the thickness T13 at the handle rear end 56b (T14 > T13. For example, T14 can be set to approximately 4.5 mm and T13 to approximately 3.8 mm).
[0099] 14 and 15, the range forming the back-side thick frame portion 60 and the tooth-side thick frame portion 70 in the handled comb 50 according to the second embodiment is the overall length L11 (dimension along the X-axis) of the entire handle 56, and extends from the handle tip 56a to the handle rear end 56b by a dimension L13 beyond the range indicated by a length dimension L12 (corresponding to the range closer to the comb back) that is half (1 / 2) of the overall length L11. The end 56f of the thick frame portion, which is the end of dimension L13, is aligned with the end of the second through-hole 57b formed in the handle 56 on the handle rear end 56b side.
[0100] Therefore, the thickness of the back side thick frame portion 60 and the tooth side thick frame portion 70 of the handled comb 50 of the second embodiment decreases toward the handle tip 56a (see Figures 14, 15, and 18), reaching a maximum in the range including the point shown in Figure 17(a) described above (the point indicated by the B1-B1 line), and gradually decreasing from that range toward the thick frame end 56f.
[0101] As such, the handled comb 50 of the second embodiment has a larger overall thickness dimension than the handled comb 1 of the first embodiment, and therefore the range of the back side thick frame portion 60 and the tooth side thick frame portion 70 formed around the peripheral contour of the handle 56 is also limited to the required range described above (the range of dimension L12 + dimension L13), minimizing the increase in weight of the handle 56 due to the thick frame portions 60, 70. At the same time, when the fingers grip the periphery of the handle 56 with their fingers, the area where the fingers are placed (the area near the back of the comb) is provided with a wide thickness dimension by the thick frame portions 60, 70, ensuring good gripping ability.
[0102] The various modifications described for the handled comb 1 according to the first embodiment can also be applied to the handled comb 50 according to the second embodiment. Furthermore, when further reducing the weight of the handled comb 50, the formation range of the thick frame portions 60, 70 may be limited to the range indicated by the above-mentioned dimension L12 (see Figures 14 and 15) (the range closer to the back of the comb), for example. [Example]
[0103] 19 to 26 show a handled comb 100 according to a third embodiment of the present invention. Like the handled combs 1 and 50 of the first and second embodiments, the handled comb 100 according to the third embodiment is a type of comb known as a clipper comb. However, while it is smaller overall in size than the handled combs 1 and 50 of the first and second embodiments, its basic configuration is similar to that of the handled comb 1 of the first embodiment. The handled comb 100 according to the third embodiment is characterized in that the widths (meaning the width dimension along the Y-axis) of the edging portions 111, 112, 121, and 122 formed on the inner peripheries of the back-side thick frame portion 110 and the tooth-side thick frame portion 120 that form the peripheral contour of the handle 106 are smaller than those of the handled combs 1 and 50 according to the first and second embodiments, and the slope angles of the edging portions 111, 112, 121, and 122 are larger.
[0104] Specifically, the handled comb 100 of the third embodiment has multiple comb teeth 103 protruding in a direction perpendicular to the longitudinal direction of the comb back portion 102, a first comb protection portion 104 and a second comb protection portion 105 extending from the front end side 102a and the rear end side 102b in the longitudinal direction of the comb back portion 102, and a handle 106 extending from the rear end side 102b of the comb back portion 102. The thickness dimension T21 (see Figures 22 and 23) of the comb portion (the portion consisting of the comb back portion 102 and multiple comb teeth 103, etc.) of the handled comb 100 is set to be the same as the thickness dimension T1 (see Figures 6 and 7) of the comb back portion 2 of the first embodiment (as an example, the thickness dimension T21 is set to be approximately 2 mm).
[0105] The comb back portion 102 has a plurality of elliptical through-holes 108 formed at equal intervals, penetrating from its front surface 102e to its back surface 102f along the Z-axis direction. Furthermore, the handle 106, which has an elongated, long, plate-like shape overall, is connected to the rear end side 102b of the comb back portion 102 and the second comb protection portion 105, as shown in Figures 19-21, and its width dimension (in the Y-axis direction) is widest at the handle tip 106a, which is connected to the comb back portion 102 and the second comb protection portion 105. The handle 106 has a total of three through-holes, a first through third handle through-hole 107a, which penetrate from the handle front surface 106e to the handle back surface 106f.
[0106] Furthermore, as shown in Figure 20, etc., the handle 106 has, within its peripheral contour, a first dorsal concave portion 130a, a first dorsal convex portion 131a, a second dorsal concave portion 130b, and a second dorsal convex portion 131b formed on the dorsal edge 106c in that order from the handle tip 106a side, and a first tooth side concave portion 132a, a first tooth side convex portion 133a, a second tooth side concave portion 132b, a second tooth side convex portion 133b, a third tooth side concave portion 132c, a third tooth side convex portion 133c, a fourth tooth side concave portion 132d, and a fourth tooth side convex portion 133d formed on the tooth side peripheral edge 106d in that order from the handle tip 106a side.
[0107] Furthermore, the handle 106 has thick frame portions 110, 120 formed on the back-side peripheral edge 106c and the tooth-side peripheral edge 106d, which face each other along the Y-axis within the peripheral outline, and which have a thickness dimension T22 (see FIGS. 22 and 23) that is larger than the thickness dimension T21 (see FIGS. 22 and 23) of the comb back portion 102. In the handled comb 100 according to the third embodiment, these thick frame portions 110, 120 do not extend to the rear end 106b of the handle. However, compared to the handled comb 50 according to the second embodiment described above, the thick frame portions 110, 120 extend to the vicinity of the rear end 106b of the handle.
[0108] Figure 25(a) is a schematic cross-sectional view showing a surface of the handle 106 cut along line C1-C1 (a line parallel to the Y-axis) passing through the deepest part of the first dorsal recessed portion 130a of the dorsal periphery 106c in Figure 20. The dorsal thick frame portion 110 (first thick frame portion) is formed on the dorsal periphery 106c, which is the lower side in Figure 25(a), and the tooth side thick frame portion 120 (second thick frame portion) is formed on the tooth side periphery 106d, which is the upper side.
[0109] The back-side thick frame portion 110 has a thickness dimension T22, which is the length from back-side frame one end 110a, which is on the handle front face 106e side, to back-side frame other end 110b, which is on the handle back face 106f side, in the direction along the Z axis (thickness direction) (an example of the actual value of thickness dimension T22 is considered to be set to about 4.7 mm). In addition, back-side frame one end 110a and back-side frame other end 110b, which are both ends in the thickness direction of the back-side thick frame portion 110, are each chamfered to round the corners, and the surface corresponding to the back-side peripheral edge 106c except for the vicinity of these ends is flat.
[0110] In the handle comb according to the third embodiment, the thickness dimension is greatest at the most convex point of the first dorsal convex portion 131a of the dorsal periphery 106c in FIG. 20 and in the range immediately before and after that in the X-axis direction (one example of the thickness dimension at the most convex point of the first dorsal convex portion 131a is set to approximately 5 mm, which is larger than approximately 4.7 mm, which is an example of the thickness dimension T22 described above).
[0111] Furthermore, the back side thick frame portion 110 forms a back side first edging portion 111 from the back side frame one end 110a, which is one end side in the thickness direction, toward the handle front surface 106e, which is inside the handle 106, and forms a back side second edging portion 112 from the back side frame other end 110b, which is the other end side in the thickness direction, toward the handle back surface 106f, which is inside the handle 106.
[0112] The back-side first edging portion 111 on the handle front surface 106e side has an edge shape of a predetermined width (meaning the width dimension along the Y-axis direction) that follows the curved shapes of the recessed portions 130a, 130b and the protruding portions 131a, 131b of the back-side periphery 106c of the handle 106, but the proportion of this width dimension along the Y-axis direction to the width dimension of the handle 106 is smaller than that of the handled combs 1, 50 according to the first and second embodiments. Specifically, the predetermined width (width dimension along the Y-axis direction) of the back-side first edging portion 111 at the location shown in Fig. 25(a) (the location shown by line C1-C1 in Fig. 20) may be set to about 3.6 mm, for example.
[0113] The first back edge portion 111 has a shape including a sloped surface that is inclined so that the thickness dimension (dimension along the Z-axis direction) becomes thinner from one end 110a of the back frame of the back periphery 106c, which is on the periphery side of the handle 106, to the handle front surface 106e, which is on the inside of the handle 106, similar to the handled combs 1 and 50 of the first and second embodiments. However, since the width dimension along the Y-axis direction is smaller as described above, the angle of the slope relative to the handle front surface 106e is larger than in the first and second embodiments.
[0114] 25(a), the back-side second edging portion 112 has a shape that is bilaterally symmetrical (flipped left and right) to the above-described back-side first edging portion 111, and has a shape that includes a slope that is inclined so that the thickness dimension (dimension along the Z-axis direction) becomes thinner from the other end 110b of the back-side frame of the back-side peripheral edge 106c, which is on the peripheral side of the handle 106, to the handle back surface 106f, which is on the inside of the handle 106. As described above, the required widths (width dimension along the Y-axis direction) of the back-side first edging portion 111 and the back-side second portion 112 are smaller than those of the edging portions 11, 12, 61, and 62 of the handled combs 1 and 50 according to the first and second embodiments, and therefore the angle of the slope with respect to the handle front surface 106e is larger than the angle of the slope of each of these edging portions 11, 12, 61, and 62.
[0115] 25(a), the tooth side thick frame portion 120 is configured as a vertical mirror image (upside down) of the above-mentioned back side thick frame portion 110, but the angle of the slope is slightly different. The tooth side thick frame portion 120 has a length from one tooth side frame end 120a on the handle front face 106e side to the other tooth side frame end 120b on the handle back face 106f side, which is the same thickness dimension T22 as the back side thick frame portion 110. The tooth side frame one end 120a and the tooth side frame other end 120b, which are both ends in the thickness direction, are chamfered to round the corners, and the surface corresponding to the tooth side peripheral edge 106d except for the vicinity of these ends is flat.
[0116] The tooth side thick frame portion 120 also forms a tooth side first edging portion 121 of a predetermined width (meaning the width dimension along the Y axis direction) extending from one tooth side frame end 120a toward the handle front surface 106e, which is inside the handle 106, and forms a tooth side second edging portion 122 of a predetermined width (meaning the width dimension along the Y axis direction) extending from the other tooth side frame end 120b toward the handle back surface 106f, which is inside the handle 106. The edging portions of the tooth side thick frame portion 120 (the tooth side first edging portion 121 and the tooth side second edging portion 122) have a slightly smaller predetermined width (meaning the width dimension along the Y axis direction) than the edging portions of the above-mentioned back side thick frame portion 110 (the back side first edging portion 111 and the back side second edging portion 112); a specific example of this is about 3.2 mm.
[0117] The tooth side first trimmed portion 121 has a shape that includes a slope (a curved slope that bulges slightly convexly) that is inclined so that the thickness dimension (dimension along the Z axis) becomes thinner from one end 120a of the tooth side frame to the handle front surface 106e (handle surface) inside the handle 106. The tooth side second trimmed portion 122 has a shape that is bilaterally symmetrical (left-right inverted) of the tooth side first trimmed portion 111 in Figure 25(a), and has a shape that includes a slope (a curved slope that bulges slightly convexly) that is inclined so that the thickness dimension (dimension along the Z axis) becomes thinner from the other end 120b of the handle tooth side frame to the handle back surface 106f inside the handle 106.
[0118] The required width (width dimension along the Y-axis direction) of these tooth-side first edge portion 121 and back-side second portion 122 is smaller than that of each edge portion 21, 22, 71, 72 of the handle combs 1, 50 of the first and second embodiments, and therefore the angle of the slope relative to the handle back surface 106f is larger than the angle of the slope of each of these edge portions 21, 22, 71, 72.
[0119] As described above, the back side thick frame portion 110 and the tooth side thick frame portion 120 shown in Figure 25(a) are formed at the opposing back side periphery 106c and tooth side periphery 106d of the most recessed portion (the portion indicated by line C1-C1) of the first back side recessed portion 130a in Figure 20, and the back side first edging portion 111 of this back side thick frame portion 110 and the tooth side first edging portion 121 of the tooth side thick frame portion 120 are spaced apart by a width dimension H22 (corresponding to the dimension from the back side first edge 111a to the tooth side first edge 121a in Figure 25(a)).
[0120] The handle front surface 106e corresponding to the range of the width dimension H22 is made flat, which makes it easy to place and press the fingers against the handle front surface 106e when gripping the handle. In order to ensure an area for placing the fingers on the handle front surface 106e, the width dimension H22 is set to be at least one-third of the width dimension H21 of the handle 106 at the location shown in Figure 25(a).
[0121] As a specific example, it is assumed that the width dimension H21 is set to approximately 23.5 mm and the width dimension H22 is set to approximately 17.2 mm. The reason for setting these numerical values is that the proportion of the width dimension H22 to the width dimension H21 of the handle 106 is the largest among the first to third embodiments for the handled comb 100 of the third embodiment. This is because a comb with a smaller overall size is generally difficult to hold securely. Therefore, to ensure a stable grip even with the small-sized handled comb 100 of the third embodiment, the proportion of the width dimension H22 is increased, thereby widening the flat handle surface 106e. Note that the above numerical values for the width dimensions H21 and H22 are merely examples and are not limited to these numerical values.
[0122] The configuration related to this width dimension H22 is also similar to the configuration related to the distance between the back-side second edging portion 112 and the tooth-side second edging portion 122 on the handle back surface 106f. That is, the back-side second edging portion 112 of the back-side thick frame portion 110 and the tooth-side second edging portion 122 of the tooth-side thick frame portion 120 are spaced apart by the length of the width dimension H22, and the range of the handle back surface 56f corresponding to this width dimension H22 is also made flat.
[0123] On the other hand, Figure 25(b) is a schematic cross-sectional view showing the surface of the handle 106 cut along the C2-C2 line (a line parallel to the Y-axis direction) that passes through the point between the first handle through-hole 107a and the second handle through-hole 107b in Figure 20. Figure 25(b) also shows the back-side thick frame portion 110 formed on the back-side peripheral edge 106c and the tooth-side thick frame portion 120 formed on the tooth-side peripheral edge 106d, but as shown in Figures 22, 23, 26, etc., the thickness of the handle 106 as a whole becomes thinner toward the handle rear end 106b, so the thickness T24 of the handle 106 shown in Figure 25(b) is smaller than the thickness T22 shown in Figure 25(a) described above.
[0124] However, at the location shown in Figure 25(b) (the location indicated by line C2-C2 in Figure 20), since the back side thick frame portion 110 and the tooth side thick frame portion 120 are present, the thickness dimension T24 is greater than the thickness dimension T23 of the handle 106 at the rear end 106b of the handle (see Figures 22, 23, and 26) (T22>T24>T23).
[0125] Note that, since the recessed portions 130a, 130b, 132a-132d and the raised portions 131a, 131b, 133a-133d described above are formed on the periphery 106c, 106d of the pattern 106, the width dimension of the pattern 106 and the spacing between the bordered portions may vary slightly from one portion to another. For this reason, the width dimension of the pattern 106 is represented by H21 in Fig. 25(a), while the width dimension of the pattern 106 is represented by H21' in Fig. 25(b). Similarly, the width dimension covering the range between the pattern front 106e and the pattern back 106f in Fig. 25(a) is represented by H22, while the width dimension covering the range between the pattern front 106e and the pattern back 106f in Fig. 25(b) is represented by H22'.
[0126] 20-23, 26, etc., the handled comb 100 according to the third embodiment does not have thick frame portions 110, 120 near the rear handle end 106b, but is formed only by the thickness of the handle 106 itself. The thick frame portions 110, 120 are formed only up to a point that is half the dimension of the first handle through-hole 107a in the X-axis direction, and the thick frame portions 110, 120 are not formed in the range from that point to the rear handle end 106b.
[0127] As described above, the handled comb 100 of the third embodiment is smaller in overall size than the handled combs 1 and 50 of the first and second embodiments, and therefore is characterized by the fact that the inclination of the slope of each edging portion of each thick frame portion 110 and 120 relative to the handle surface is increased, and the proportion of the width dimension between the edging portions (for example, the width dimension H22 shown in Figure 25(a)) is increased, ensuring a wide area of the flat handle surface and making it easier to place fingers on the handle surface even with a small size.
[0128] In addition, the various modified examples described for the handled combs 1 and 50 of the first and second embodiments can also be applied to the handled comb 100 of the third embodiment, and the configurations applied to the handled combs 1 and 50 of the first and second embodiments can also be applied to the handled comb 100 of the third embodiment. [Industrial Applicability]
