Description

Technical Field

[0001] This utility model relates to a handle comb that ensures the rigidity of the handle and improves the ease of gripping the handle. Background Technology

[0002] Traditionally, combs were generally used for styling hair by combing it with multiple teeth that protrude from the back of the comb, which is shaped like a ridge. However, as professional users, beauticians and hairdressers sometimes use combs when trimming hair with clippers. Thus, the use of combs in trimming with clippers is mostly seen in Europe and other regions. In addition, combs with structures suitable for trimming purposes are generally called razor combs.

[0003] Patent Document 1 below discloses an example of a comb used in hair clipping. In Patent Document 1... Figure 7 Figure 8 illustrates an example of using a comb in hair trimming with clippers. The comb is placed against the scalp at the collar, sides, or other areas where the hair is being trimmed. The comb is moved from bottom to top, using its multiple teeth to comb the hair, ensuring that hair is separated from the teeth. The clippers then trim this separated hair. During trimming, the clippers contact the multiple teeth and slide along them, ensuring that the remaining hair after cutting is of uniform length.

[0004] Furthermore, as another example of a comb suitable for trimming, known as a razor comb, there are handle-type combs (handled combs) as shown in Patent Documents 2 and 3. Such handle-type combs have a dedicated handle for gripping, thus allowing for trimming operations while holding the handle. Therefore, even when moving the clippers during trimming, it is easy to maintain the comb in a stable posture, which is preferable. Additionally, these combs shown in Patent Documents 2 and 3 were created by the same person as the designer of this utility model.

[0010] The problem to be solved by utility models

[0011] When using a hair clipper with the aforementioned comb to trim hair, the length of the remaining hair after trimming depends on the thickness of the comb. Physically, it is impossible to trim hair in a way that is shorter than the thickness of the comb. Therefore, in order to shorten the trimmed hair length, it is necessary to reduce the thickness of the comb itself.

[0012] However, if the thickness of the comb itself is reduced, the rigidity of the comb decreases. In particular, in the combs with handles shown in Patent Documents 2 and 3 above, the thickness of the handle is also reduced, and the rigidity of the handle is reduced. Therefore, the comb becomes difficult to hold, and there is a problem that it is difficult to perform hair trimming operations stably using the hair clipper.

[0013] Furthermore, in combs with handles, the way the handle is held varies depending on the user. For example, some users grip the upper and lower contours of the handle (e.g., the perimeter near the back of the comb) with their fingertips. For users who grip the handle by its contours in this way, if the thickness of the handle is too thin, it becomes difficult to maintain a stable grip on the comb. Other methods of holding the handle include placing the thumb and forefinger on the front and back surfaces of the handle. Thus, there are various ways to hold the handle of a comb, but regardless of the method, the rear end of the handle generally contacts the palm to stabilize the comb's position.

[0014] Furthermore, to address the aforementioned issues, one could envision not uniformly thinning the entire comb, but rather increasing the thickness of only the handle portion. This would ensure the handle's rigidity and prevent a decrease in ease of grip. However, if only the handle were thickened, it would become heavier, shifting the weight closer to the handle's center of gravity, resulting in poor balance and making the comb difficult for the user to use.

[0015] This utility model was made in view of the above situation, and its purpose is to provide a comb with a handle that is also suitable for trimming operations with a hair clipper. Even if the hair can be trimmed shorter with a hair clipper, the rigidity of the handle can be ensured while preventing the overall balance of the comb from deteriorating, and the handle can also be ensured to have good grip.

[0016] Solution for solving the problem

[0017] To address the aforementioned issues, Solution 1 of this utility model provides a comb with a handle, comprising a ridge-shaped comb back, multiple comb teeth protruding from the comb back, and a long plate-shaped handle extending from the comb back. The handle is characterized in that, on the handle, thick frame portions with a thickness larger than that of the comb back are formed at opposite peripheries in the surrounding contour, and the thickness of the handle thins towards the rear end of the handle.

[0018] In this invention, two opposing peripheries in the width direction of the handle are formed with thicker frame portions, the thickness of which is greater than that of the back of the comb. Therefore, these thicker frame portions function structurally like ribs, ensuring the required rigidity of the handle. Furthermore, by forming such thicker frame portions, the area in contact with the user's fingertips becomes a thicker section with a larger thickness when gripping, thus ensuring the required contact area relative to the fingertips and making the handle easier to grip. Preferably, these thicker frame portions are formed in the handle's contour, including a region near the back of the comb that facilitates gripping when holding the handle.

[0019] Furthermore, since the thickness of the handle gradually decreases towards the rear end, the weight increase of the handle is suppressed compared to increasing the overall thickness of the handle in the same way. As a result, the center of gravity of the comb is prevented from being extremely close to the handle, the overall weight distribution of the comb is prevented from deteriorating, and the ease of use of the comb is maintained.

[0020] Furthermore, the comb with a handle according to Scheme 2 of this utility model is characterized in that a edging portion of predetermined width is formed on the inner periphery of the coarse frame portion, the edging portion including a beveled surface that is inclined in such a way that the thickness dimension decreases from the periphery side of the handle to the inward side.

[0021] In this invention, regarding the thick frame portion, an edging portion is formed on the inner periphery of the thick frame portion that forms around the outline of the handle. This edging portion is formed as a sloped surface that thins from the outline inwards. Therefore, for users who grip the handle by pinching the front and back surfaces of the handle with their thumb and forefinger, the sloping edging portion functions as a finger guide and improves finger hooking. Thus, the gripping performance of the handle is improved compared to the past. Especially when the user is a beautician, various liquids adhere to the fingers, and the comb is often held in a state where the fingertips easily slip. Therefore, the edging portion acts as a non-slip part, ensuring good ease of use.

[0022] The comb with a handle according to Solution 3 of this utility model is characterized in that the edging portions of the thick frame portion formed on the opposite periphery are spaced apart from each other by a length of more than 1 / 3 of the width dimension of the handle in the portion where the edging portions are spaced apart from each other, and the handle surface of the portion where the edging portions of the thick frame portion are spaced apart is flat.

[0023] In this invention, the edging portions at opposite edges are separated by a length at least one-third of the handle's width, and the handle surfaces between the edging portions are flat. Therefore, for users who grip the handle by placing their fingertips on the handle surface, a flat surface for fingertip placement is ensured. Furthermore, this surface is held in place by the beveled edging portions, thus the fingertips positioned on the flat surface are assisted or guided from both sides by the edging portions, improving the ease of fingertip placement and the stability of the fingertips positioned on the handle surface, thereby ensuring good handle grip. In this invention, "flat" handle surface means that the basic structure of the handle surface is flat. For example, even if a hole is formed on the flat handle surface, the handle surface is still flat. Additionally, even if text, patterns, etc., are formed on the flat handle surface in a raised manner, the handle surface is still flat.

[0024] Furthermore, by ensuring that the spacing between the opposing edging portions is at least one-third the length of the handle in the width direction, the coarse frame containing the edging portions will not unnecessarily increase in size. This suppresses an increase in the weight of the handle and maintains the balance of the comb's center of gravity. In addition, the upper limit of the length of the spacing between the edging portions is the degree to which each edging portion can maintain a bevel.

[0025] The comb with a handle according to Scheme 4 of this utility model is characterized in that, in the outline around the handle, within the area where the thick frame portion is formed, a concave portion and a convex portion are formed, the concave portion being located near the back of the comb relative to the convex portion.

[0026] In this invention, since a thick frame is formed on the concave and convex parts of the outline, and the concave part is located closer to the back of the comb than the convex part, for users who grip the outline of the handle, their fingertips are accommodated in the concave part near the back of the comb, and the convex part assists in positioning the fingers accommodated in the concave part. Moreover, these convex and concave parts ensure a larger contact area relative to the fingertips through the thick frame, thus further improving the ease of gripping the outline of the handle.

[0027] The comb with a handle according to Solution 5 of this utility model is characterized in that the edging portion is formed along the curved shape of the concave portion and the convex portion.

[0028] In this invention, the edging portion of the thick frame is formed into a shape with curved concave and convex portions along the surrounding contour. Therefore, it is formed in a way that matches the concave and convex features of the edging portion to the surrounding contour. As a method of gripping the handle, this ensures a comfortable grip suitable for users who grip the handle by placing one finger (e.g., index finger) in contact with the contour of the handle and another finger (e.g., thumb) in contact with the surface of the handle. That is, the concave and convex features are the same for both the surrounding contour of the handle and the edging portion around the handle surface. Therefore, even when one finger (e.g., index finger) contacts the concave portion of the surrounding contour, the edging portion, through the same concave and convex features, ensures that a surface portion of a predetermined width can be properly supported by another finger on the handle surface, resulting in good handle grip.

[0029] The comb with a handle according to Scheme 6 of this utility model is characterized in that the thick frame portion and the edging portion are formed around the entire circumference of the handle.

[0030] In this invention, because a thick frame and an edge portion are formed along the entire circumference of the handle, the overall rigidity of the handle is improved. Even when using the hair clipper for trimming, the grip on the comb remains stable, allowing the hair clipper to move steadily and facilitating effective trimming. In particular, regardless of how the user holds the handle, the rear end of the handle is designed to contact the palm. Therefore, even under loads generated by a certain gripping pressure, the thick frame and edge portion along the entire circumference ensure sufficient and continuous rigidity at the rear end of the handle, providing the user with a firm and stable grip.

[0031] Effects of the utility model

[0032] In this invention, since a thick frame portion is formed at the desired part of the handle outline, the rigidity of the handle can be ensured, and sufficient area can be ensured for the fingers to fit snugly when the handle outline is clamped and held, thereby providing good handle grip. In addition, since the thickness of the handle thins towards the rear end, the weight increase of the handle can be suppressed even with the formation of the thick frame portion, thus preventing the overall weight balance of the comb from deteriorating.

[0033] Furthermore, in this invention, a beveled edge portion is formed on the inner periphery of the thick frame portion. Therefore, when the surface of the handle is held with the fingertips, the beveled edge portion guides the fingers as a guide, making it easy to position the fingers to hold the handle. Moreover, once the handle is held with the fingers, the degree of hooking of the fingers on the edge portion is also increased, thus improving the gripping performance of the handle and ensuring good handle grip.

[0034] Furthermore, in this invention, since the opposing edging portions are separated from each other by a length of more than 1 / 3 of the width of the handle, and a plane is formed at the part between them, when the fingertips are held against the surface of the handle, the fingertips arranged on the surface of the handle can be stably arranged with a flat surface, and the thick frame portion including the edging portion will not become too large. Thus, the weight of the handle can be prevented from becoming too heavy, and the weight balance of the comb as a whole can be avoided.

[0035] Furthermore, in this invention, since a rough frame is formed on the concave and convex parts of the handle's outline, and the concave part is positioned closer to the back of the comb than the convex part, when the fingers are held on the outline of the handle, the convex part can be used to guide the fingertips to be placed in the concave part near the back of the comb. Moreover, if the fingertips are temporarily placed in the concave part, the convex part can be used to assist in preventing the fingers from moving. Therefore, the grip when holding the handle with the fingers on the outline of the handle can be further improved.

[0036] In this invention, since the edging portion of the thick frame is formed into a shape that bends along the concave and convex parts of the surrounding contour of the handle, it is possible to form a shape that connects and matches the concave and convex parts of the surrounding contour, thereby improving the grip on the surrounding contour of the handle and the surface of the handle.

[0037] In addition, in this invention, since a rough frame and an edge portion are formed around the entire circumference of the handle, the overall rigidity of the handle can be improved, and a rough gripping feel can be provided to the user when holding the handle. Attached Figure Description

[0064] [Example 1]

[0065] Figures 1 to 1 0 indicates the comb 1 with a handle according to the first embodiment of this utility model. The comb 1 with a handle of this utility model is a type of comb called a scraper comb, which is integrally molded from synthetic resin. As a general structure, the comb 1 has multiple comb teeth 3 protruding in a direction orthogonal to the length direction of the comb back 2, which is a ridge-shaped comb body. The first comb protection part 4 and the second comb protection part 5 extend parallel to the protruding direction of each comb tooth 3 from the front end side 2a (one end side) and the rear end side 2b (the other end side) of the comb back 2 in a manner that clamps the multiple comb teeth 3, thereby protecting the comb teeth 3. Furthermore, the handle 6 extends from the rear end side 2b of the comb back 2 along the length direction of the comb back 2.

[0066] in addition, Figure 1The X-axis shown is along the length of the comb back 2, which extends in a ridge-like shape. The Y-axis, orthogonal to the X-axis, is along the protruding direction of the comb teeth 3 (which also corresponds to the width direction of the handle 6). The Z-axis, orthogonal to both the X-axis and Y-axis, is along the thickness direction of the comb 1, the comb back 2, and the handle 6 (these directions are also the same in other figures). Furthermore, in Figure 1 In the diagram, the arrow representing the X-axis points from the rear end side 2b of the comb back 2 towards the front end side 2a, the arrow representing the Y-axis points in the direction in which the comb teeth 3 protrude from the comb back 2, and the arrow representing the Z-axis points from the back side of the comb 1 towards the front side (the orientation of each arrow is the same in other diagrams).

[0067] The comb 1 with a handle in the first embodiment can trim hair shorter through a hair clipper operation, thus its comb portion (comprising the comb back 2 and multiple comb teeth 3, etc.) is thinner than that of a regular comb. As a specific example, the thickness T1 of the comb back 2 in the first embodiment (refer to...) Figure 6 , Figure 7 The setting is approximately 2mm.

[0068] The back 2 of such a comb has multiple through holes 8 extending from its front side 2e to the opposite back side 2f along the Z-axis. These through holes 8 are elliptical in shape and are arranged in a straight line along the X-axis at predetermined intervals (see reference). Figure 1 , Figure 3 , Figure 5 (etc.). Additionally, such as Figure 1 As shown, the comb 1 has multiple comb teeth 3 protruding from the inner surface 2d of the back of the comb 2 on the side opposite to the back surface 2c, between the first comb protection part 4 and the second comb protection part 5. When viewed as a whole, these multiple comb teeth 3 form a structure in which they are connected and arranged in a planar shape, and the planar portion in which the multiple comb teeth 3 are connected is oriented parallel to the XY plane based on the X-axis and Y-axis.

[0069] The handle 6, extending along the X-axis from the rear end side 2b of the comb back 2, is a long, slender, plate-like shape. (Example) Figure 4 As shown, the handle 6 is connected to the rear end side 2b of the comb back 2 and also to the second comb protection part 5, making the width dimension (along the Y-axis direction) of the front end 6a of the handle, which is connected to the comb back 2 and the second comb protection part 5, the widest. Furthermore, in this embodiment, the second comb protection part 5... Figure 4 The area is defined as the region enclosed by a dashed rectangle.

[0070] In addition, such as Figure 2 , Figure 5As shown, the handle 6 has a total of three through holes 7a to 7c extending from the front 6e to the back 6f of the handle. The first through hole 7a, located on the side closest to the rear 6b ​​of the handle, is a combination of a semicircle and a pentagon. The second and third through holes 7b are heart-shaped. Each of the through holes 7a to 7c has a significantly larger opening ratio compared to the elliptical through hole 8 formed on the back 2 of the comb. Therefore, by forming these first through holes 7a to 7c, the weight of the handle 6 is reduced.

[0071] Furthermore, such as Figure 4 As shown, the handle 6 has multiple concave portions 30a, 30b, 32a-32d and convex portions 31a, 31b, 33a-33d formed on its surrounding contour in the front view (e.g., Figure 3 , Figure 4 The shape is curved downwards (as shown in the view direction).

[0072] Specifically, the handle 6, in its surrounding contour, on the side corresponding to the back of the comb 2 (bottom side), Figure 3 , Figure 4 On the back periphery 6c (the side below), starting from the front end 6a of the handle, a first back concave portion 30a, a first back convex portion 31a, a second back concave portion 30b, and a second back convex portion 31b are sequentially formed. Furthermore, on the side corresponding to the orientation of the tips of each comb tooth 3 (in... Figure 3 , Figure 4 The tooth lateral periphery 6d (which becomes the upper side) is formed sequentially from the front end 6a side of the shank, including the first tooth lateral concave portion 32a, the first tooth lateral convex portion 33a, the second tooth lateral concave portion 32b, the second tooth lateral convex portion 33b, the third tooth lateral concave portion 32c, the third tooth lateral convex portion 33c, the fourth tooth lateral concave portion 32d, and the fourth tooth lateral convex portion 33d.

[0073] like Figure 4 As shown, in the back-side recesses 30a and 30b formed on the back-side periphery 6c of the handle 6, the first back-side recess 30a, which is closer to the back of the comb 2, has a shorter length along the extension direction of the handle 6 (along the X-axis direction) compared to the second back-side recess 30b, and is set to a size corresponding to a person's fingertip. Therefore, for users who hold the handle 6 in a certain shape, it is easy to place their fingers on the first back-side recess 30a.

[0074] Furthermore, among the tooth-side recesses 32a to 32d formed on the tooth-side periphery 6d of the handle 6, the fourth tooth-side recess 32d near the rear end 6b of the handle has a longer length dimension along the extension direction of the handle 6 (along the X-axis direction) compared to the other first tooth-side recesses 32a to third tooth-side recesses 32c. The remaining first tooth-side recesses 32a to third tooth-side recesses 32c are similarly set to a length dimension corresponding to the fingertip of a person, making it easy for the user's fingers to fit on these tooth-side recesses 32a to 32c.

[0075] Furthermore, the reason for providing three toothed recessed portions 32a to 32c on the toothed periphery 6d of the handle 6, which are easy to fit the fingers, is that when holding the outline of the handle 6, the user's index finger usually rests on one side of the toothed periphery 6d. The index finger is easier to move than the thumb. As such, the outline portion that is held by the fingers when holding the handle 6 varies greatly from user to user, thus accommodating various users' holding methods.

[0076] Furthermore, the first back-side recess 30a formed on the back-side periphery 6c and the first tooth-side recess 32a formed on the tooth-side periphery 6d are subtly offset in the X-axis direction (the first tooth-side recess 32a is formed slightly closer to the back of the comb 2 than the first back-side recess 30a). This is because, considering that when the user holds the handle 6 with their fingers, the positions of the thumb, which is close to the back-side periphery 6c, and the index finger, which is close to the tooth-side periphery 6d, are slightly different in the X-axis direction.

[0077] Furthermore, the number of concave portions 30a-30b, 32a-32d and convex portions 31a-31b, 33a-33d on the back periphery 6c and tooth periphery 6d of the handle 6 is different. As a result, the positions of the first back convex portion 31a on the back periphery 6c closest to the back of the comb 2 and the first tooth convex portion 33a on the tooth periphery 6d are also staggered in the X-axis direction.

[0078] That is, the number of protruding and concave portions on the toothed periphery 6d of the handle is greater than the number of protruding and concave portions on the back periphery 6c. Therefore, the first toothed protruding portion 33a of the toothed periphery 6d is formed in the X-axis direction closer to the back of the comb 2 than the first back protruding portion 31a of the back periphery 6c, and the first back protruding portion 31a of the back periphery 6c is formed closer to the second toothed concave portion 32b of the toothed periphery 6d. By arranging the protruding portions 31a-31b and 33a-33d in such a position, when the user places their fingers on the periphery of the handle 6, it is easy to guide the fingertips to the aforementioned concave portions 30a-30b and 32a-32d, and it helps to easily and stably maintain (hold) the fingertips stored in the concave portions 30a-30b and 32a-32d.

[0079] Furthermore, as a feature of this invention, the handle 6 has a thickness dimension T1 that is greater than the thickness dimension T1 of the comb back 2 in its surrounding contour, specifically on the back periphery 6c and the tooth periphery 6d, which are opposite each other along the Y-axis direction (see reference). Figure 6 , Figure 7 Large, thick frame parts 10 and 20.

[0080] Figure 9(a) shows that in Figure 4 The schematic cross-sectional view of the face of the handle 6 cuts through the most concave part of the first back-side recess 30a of the back-side periphery 6c by the line A1-A1 (a line parallel to the Y-axis direction). In FIG9(a), the back-side periphery 6c, which is the lower side, has a back-side rough frame portion 10 (first rough frame portion), and the tooth-side periphery 6d, which is the upper side, has a tooth-side rough frame portion 20 (second rough frame portion).

[0081] The part of the handle 6 at the cut surface in Figure 9(a) Figure 4 Within the range from the part shown by line A1-A1 to the first back side protrusion 31a, the thickness of the handle 6 is the greatest. The thickness dimension T2 of the part shown in Figure 9(a) can be considered to be set to about 6.2 mm as an example.

[0082] The length of the back side rough frame portion 10 along the Z-axis direction (thickness direction), from one end 10a of the back side frame that becomes the front side 6e of the handle to the other end 10b of the back side frame that becomes the back side 6f of the handle, is the thickness dimension T2. ​​The back side frame one end 10a and the other end 10b, which become the two ends in the thickness direction, are chamfered and the corners are rounded. The surface corresponding to the back side perimeter 6c near these two ends is flat.

[0083] Furthermore, the back side rough frame portion 10 forms a back side first edging portion 11 on the inner periphery of the handle front 6e side, and a back side second edging portion 12 on the inner periphery of the handle back 6f side. In detail, the back side first edging portion 11 is formed from one end 10a of the back side frame, which is one end in the thickness direction (Z-axis direction), toward the handle front 6e, which is the inner side of the handle 6, and the back side second edging portion 12 is formed from the other end 10b of the back side frame, which is the other end in the thickness direction (Z-axis direction), toward the handle back 6f, which is the inner side of the handle 6.

[0084] like Figure 3 , Figure 4 As shown, the first back edge portion 11 formed on the front side 6e of the handle has a predetermined width (referring to the width dimension along the Y-axis) on the inner periphery of the back frame portion 10, and becomes an edge shape that curves along the concave portions 30a, 30b and convex portions 31a, 31b of the back periphery 6c of the handle 6.

[0085] For example, the first back-side edging portion 11 corresponding to the first back-side concave portion 30a is bent into a concave shape along the back-side periphery 6c of the first back-side concave portion 30a, forming a convex edge shape that bends inward toward the handle 6. Similarly, the first back-side edging portion 11 corresponding to the first back-side convex portion 31a is bent into a convex shape along the back-side periphery 6c of the first back-side convex portion 31a, forming a convex edge shape that bends outward toward the handle 6. The structure involving such a predetermined width shape of the first back-side edging portion 11 is also present in the second back-side edging portion 12 formed on the back side of the handle back 6f.

[0086] It should be noted that the part shown in Figure 9(a) ( Figure 4 The predetermined width (width along the Y-axis) of the first edging portion 11 on the back side of the part shown by line A1-A1 in the figure can be set to about 7mm as an example.

[0087] In addition, such as Figure 4 , Figure 5 As shown, for example, the second back-side trim portion 12 corresponding to the first back-side concave portion 30a is also bent into a concave shape along the back-side periphery 6c of the first back-side concave portion 30a, similar to the first back-side trim portion 11 described above, and becomes a convex shape bent towards the inside of the handle 6. In addition, the second back-side trim portion 12 corresponding to the first back-side convex portion 31a is bent into a convex shape along the back-side periphery 6c of the first back-side convex portion 31a, and becomes a convex shape bent towards the outside of the handle 6.

[0088] Furthermore, as shown in Figures 9(a) and 9(b), the back-side first edging portion 11 is shaped as a sloped surface that tapers in thickness (dimension along the Z-axis) from the back-side frame end 10a, which forms the periphery of the handle 6, toward the handle front 6e, which forms the inner side of the handle 6. That is, the back-side first edging portion 11 is a sloped surface that has the greatest thickness at the back-side frame end 10a and the smallest thickness at the innermost back-side first edge end 11a, which forms the handle 6. Additionally, the slope of the back-side first edging portion 11 is not flat, but rather a slightly convex, raised surface.

[0089] Furthermore, in Figure 9(a), the second back-side edging portion 12 is symmetrical (reversed left and right) to the first back-side edging portion 11, and is shaped as a sloped surface that thins in thickness (dimension along the Z-axis) from the other end 10b of the back-side frame, which forms the peripheral edge 6c of the handle 6, toward the handle back 6f, which forms the inner side of the handle 6. Therefore, the second back-side edging portion 12 is also a sloped surface that is the thickest at the other end 10b of the back-side frame and the thinnest at the innermost second back-side edge 12a, which forms the handle 6. In addition, the sloped surface of the second back-side edging portion 12 is also a slightly curved, convex surface.

[0090] On the other hand, in Figure 9(a), the upper toothed rough frame portion 20 is a structure that makes the aforementioned back rough frame portion 10 vertically symmetrical (vertically reversed), but the angle of the slope of the shape itself is slightly different.

[0091] Specifically, regarding the toothed rough frame portion 20, the length from one end 20a of the toothed frame that becomes the front side 6e of the handle to the other end 20b of the toothed frame that becomes the back side 6f of the handle is set as the thickness dimension T2. ​​The toothed frame that becomes the two ends in the thickness direction, one end 20a and the other end 20b, are chamfered and the corners are rounded. The surface corresponding to the toothed periphery 6d near these two ends is flat, and the structure near it is the same as that of the back rough frame portion 10 described above.

[0092] Furthermore, the toothed frame portion 20 also forms a first toothed edging portion 21 on the inner periphery of the front side 6e of the handle, and a second toothed edging portion 22 on the inner periphery of the back side 6f of the handle. In detail, the first toothed edging portion 21 is formed from one end 20a of the toothed frame toward the front side 6e of the handle, which is the inner side of the handle 6, and the second toothed edging portion 22 is formed from the other end 20b of the toothed frame toward the back side 6f of the handle, which is the inner side of the handle 6.

[0093] like Figures 3-5 As shown, the first toothed edge portion 21 formed on the front side 6e of the handle has a predetermined width (meaning the width along the Y-axis), forming an edge shape with curved portions 32a-32d and convex portions 33a-33d along the toothed periphery 6d of the handle 6. The structure involving this predetermined width shape of the first toothed edge portion 21 is also present in the second toothed edge portion 22 formed on the back side 6f of the handle. It should be noted that the portion shown in Figure 9(a)... Figure 4The predetermined width (width along the Y-axis) of the tooth-side first edging portion 21 of the part shown by line A1-A1 in Figure 9(a) can be set to about 5.8 mm, which is smaller than the predetermined width (about 7 mm) of the back-side first edging portion 11 of the part shown by line A1-A1 in Figure 9(a).

[0094] Furthermore, the tooth-side first edging portion 21 is shaped with a slope that is inclined in such a way that the thickness (dimension along the Z-axis) decreases from one end 20a of the tooth-side frame, which is the tooth-side periphery 6d, which is the peripheral side of the handle 6, toward the handle front 6e, which is the inner side of the handle 6. Such a slope is a slightly curved, convex surface. In addition, as described above, in the part shown in FIG9(a), the predetermined width of the tooth-side first edging portion 21 is smaller than the predetermined width of the back side first edging portion 11. Therefore, the angle of the slope of the tooth-side first edging portion 21 relative to the handle front 6e is larger than that of the slope of the back side first edging portion 11.

[0095] In addition, in Figure 9(a), the second edge portion 22 of the tooth side is a shape that makes the first edge portion 21 of the tooth side symmetrical (reversed left and right). It is a shape that includes a sloped surface that is thinned in a way that the thickness dimension (the dimension along the Z-axis direction) from the other end 20b of the tooth side frame that becomes the peripheral edge 6d of the tooth side of the handle 6 towards the back surface 6f of the handle that becomes the inner side of the handle 6. This sloped surface is a slightly curved and convex surface.

[0096] Furthermore, as described above, the back-side rough frame portion 10 and the tooth-side rough frame portion 20 shown in FIG9(a) are formed in Figure 4 The most concave part of the first back side recessed part 30a (the part shown by line A1-A1) has a back side perimeter 6c opposite to the tooth side perimeter 6d, but the back side first edging part 11 of the back side rough frame part 10 and the tooth side first edging part 21 of the tooth side rough frame part 20 are separated by a length of width dimension H2 (equivalent to the dimension from the back side first edge end 11a to the tooth side first edge end 21a in FIG. 9(a)).

[0097] Furthermore, the front surface 6e of the handle, corresponding to the dimension from the first edge end 11a on the back side to the first edge end 21a on the toothed side, is flat. This ensures a flat surface for the fingers to grip the handle 6 when they are placed on the front surface 6e. In such a front surface 6e, to ensure sufficient area for the fingers to grip, the width dimension H2, from the first edge end 11a on the back side to the first edge end 21a on the toothed side, is ensured to be at least one-third of the width dimension H1 of the handle 6 in the portion shown in FIG. 9(a) (the portion shown by line A1-A1). As a specific example, it is conceivable that the width dimension H1 is set to approximately 24 mm and the width dimension H2 to approximately 11 mm, but these values ​​are not strictly limited.

[0098] It should be noted that the structure relating to the spacing between the back side first edging portion 11 and the tooth side first edging portion 21 at the front of the handle 6e is also the structure relating to the spacing between the back side second edging portion 12 and the tooth side second edging portion 22 at the back of the handle 6f. That is, the back side second edging portion 12 of the back side rough frame portion 10 and the tooth side second edging portion 22 of the tooth side rough frame portion 20 are separated by a length of width dimension H2 (corresponding to the dimension from the back side second edge end 12a to the tooth side second edge end 22a in FIG. 9(a)). The back of the handle 6f, corresponding to the dimension from the back side second edge end 12a to the tooth side second edge end 22a, is flat. Moreover, the width dimension H2 from the back side second edge end 12a to the tooth side second edge end 22a is also more than 1 / 3 of the width dimension H1 of the handle 6.

[0099] Additionally, Figure 9(b) shows that in Figure 4 A schematic cross-sectional view of the surface of the shank 6 cut off by line A2-A2 (a line parallel to the Y-axis) at the portion between the first shank through hole 7a and the second shank through hole 7b. Figure 9(b) also shows the back-side rough frame portion 10 formed on the back-side periphery 6c and the tooth-side rough frame portion 20 formed on the tooth-side periphery 6d, but the shank 6 as a whole... Figure 6 , Figure 7 As shown, its thickness decreases towards the rear end 6b of the handle. Therefore, the portion shown in Figure 9(b) is closer to the rear end 6b of the handle than the portion shown in Figure 9(a). Consequently, the thickness T4 of the handle 6 shown in Figure 9(b) is thinner than the thickness T2 shown in Figure 9(a). However, the portion shown in Figure 9(b) also contains the back-side rough frame portion 10 and the tooth-side rough frame portion 20. Therefore, the thickness T4 is thinner than the thickness T3 of the handle 6 at the rear end 6b of the handle (see Figure 9(b)). Figure 6 , Figure 7 ) large (T2>T4>T3).

[0100] Furthermore, as described above, recessed portions 30a, 30b, 32a-32d and convex portions 31a, 31b, 33a-33d are formed on the periphery 6c and 6d of the handle 6. Therefore, the width dimension of the handle 6 and the spacing between the edging portions are sometimes slightly different values ​​in each part in the X-axis direction. Therefore, in FIG9(a), the width dimension of the handle 6 is represented by H1, and on the other hand, in FIG9(b), the width dimension of the handle 6 is represented by H1′. Similarly, in FIG9(a), the width dimension of the area encompassing the front 6e and back 6f of the handle is represented by H2, and on the other hand, in FIG9(b), the width dimension of the area encompassing the front 6e and back 6f of the handle is represented by H2′.

[0101] Moreover, such as Figure 6 , Figure 7 As shown in Figure 10, the back-side rough frame portion 10 of the back periphery 6c and the tooth-side rough frame portion 20 of the tooth-side periphery 6d are formed to extend to the rear end 6b of the handle, where they are connected. Thus, by connecting the back-side rough frame portion 10 and the tooth-side rough frame portion 20 at the rear end 6b of the handle, rough frames (back-side rough frame portion 10 and tooth-side rough frame portion 20) are formed around the entire circumference of the surrounding contour (the surrounding contour in the front view) of the handle 6. Furthermore, the back-side rough frame portion 10 and the tooth-side rough frame portion 20 are also formed to the front end 6a of the handle, but their thickness decreases towards the front end 6a (see Figure 10). Figure 6 , Figure 7 (Figure 10, etc.)

[0102] As described above, in the outline of the comb 1 with handle according to the present invention, the opposite peripheries (back periphery 6c and tooth periphery 6d) in the width direction (along the Y direction) of the handle 6 are respectively formed with the above-described coarse frame portions (back coarse frame portion 10 and tooth coarse frame portion 20). Therefore, such coarse frame portions with such thick dimensions function like ribs in structure, ensuring the required rigidity of the handle 6 even if the handle 6 has a thin basic thickness dimension, and preventing the handle 6 from becoming heavy compared to the case where the thickness of the handle 6 is increased uniformly.

[0103] In particular, regarding ensuring rigidity, in the first embodiment, the rough frame portions 10 and 20 and the edging portions 11, 12, 21, and 22 are formed around the entire circumference of the handle 6. Therefore, the entire circumference of the handle 6 forms a rib structure, and even if the thickness of the inner side of the handle 6 is as thin as that of the comb back 2, the handle 6 can still have a strong and rigid feel overall. In addition, regarding the handle 6, the fact that the overall thickness thins towards the rear end 6b of the handle also helps to suppress the weight of the handle 6 and prevents the overall center of gravity of the comb from deteriorating.

[0104] Furthermore, the back-side rough frame portion 10 and the tooth-side rough frame portion 20 formed on the periphery 6c and 6d of the shank 6 ensure the thickness dimension T2 (see reference). Figure 6 , Figure 7 The relatively thick thickness ensures that the surface of the handle 6, which has such a thick frame 10, 20, is larger than that of a regular comb. Therefore, for users who hold the handle by pinching the periphery of the handle with their fingers, the larger area that is close to the fingertips increases the ease of holding the handle 6.

[0105] Furthermore, since concave portions 30a, 30b, 32a-32d and convex portions 31a, 31b, 33a-33d are provided in a curved shape on the periphery of the handle 6, and thick frame portions 10 and 20 are formed on these concave and convex portions 30a-33d, when the fingers are placed on the periphery 6c and 6d of the handle 6, if the fingertips are guided to the concave portions 30a by the convex portions 31a, etc., and the fingertips are temporarily accommodated in the concave portions 30a, etc., the concave curved shape and the position of the fingertips by the convex portions 31a, etc. are stabilized. Therefore, through the synergistic effect with the thick frame portions 10 and 20, it is easier to grip the periphery of the handle 6 with the fingers.

[0106] Furthermore, the rough frame portions 10 and 20 formed on the handle 6 have beveled edging portions 11, 12, 21, and 22 extending inward from the periphery 6c and 6d of the handle 6 with a predetermined width. Therefore, for users who hold the handle 6 by placing their fingers on the surface of the handle 6, such edging portions 11, 12, 21, and 22 serve as guides to guide the fingertips toward the surface of the handle 6. Once the fingers are placed on the surface of the handle 6, these edging portions 11, 12, 21, and 22 increase the degree of finger hooking, thus improving the grip performance of the handle.

[0107] Furthermore, as shown in Figure 9(a), the spacing between the edging portions 11 and 21 opposite to each other on the front side 6e of the handle and the edging portions 12 and 22 opposite to each other on the back side 6f of the handle ensures that the width dimension H2 is at least 1 / 3 (one-third) of the width dimension H1 of the handle 6. The handle surface (front side 6e and back side 6f) within the range of this width dimension H2 is formed into a plane that is easy to press with the fingers. Therefore, a sufficiently flat area for pressing against the fingertips can be ensured, which can improve the stability when the handle 6 is gripped with the fingers that are pressed against the handle surface and ensure good grip of the handle 6.

[0108] Furthermore, the comb 1 with handle according to the first embodiment is not limited to the above structure, and various modifications are conceivable. For example, the thick frame portions 10 and 20 are not formed around the entire circumference of the handle 6, but can be conceivable as being formed only in the required areas.

[0109] As required, when the handle 6 is held by fingers along its surrounding contour, since the area within the handle 6 where the fingers frequently come into contact with the back of the comb 2, it is considered to form a thick frame portion 10, 20 within the periphery 6c, 6d of the handle 6, specifically within the area close to the back of the comb. As an example of the area close to the back of the comb, relative to... Figure 6 , Figure 7The overall length L1 (dimension along the X-axis) of the handle 6 shown is defined as the range of the length L2, which is half (1 / 2) of the overall length L1, starting from the front end 6a of the handle, and is located near the back of the comb 2. If limited to such a defined range (e.g., in...), Figure 6 , Figure 7 If the thick frame portions 10 and 20 are formed within the range indicated by the length dimension L2, it has the advantage of being able to suppress the increase in weight of the handle 6 caused by the thick frame portions 10 and 20.

[0110] Alternatively, the thicker frame portions 10 and 20 may not be formed such that the thickness increases on both sides of the handle front 6e and handle back 6f, but rather the thickness increases only on the handle front 6e side or handle back 6f side, while the other side remains a flat surface shape.

[0111] In this modified example, since either the front side 6e or the back side 6f of the handle can be formed as a flat surface (plane), when using the hair clipper for trimming, if such a flat surface is placed on the scalp, it is easy for the comb 1 with the handle to follow the scalp precisely. Furthermore, compared to the case where the thicker frame portions 10 and 20 are formed with increasing thickness towards both the front side 6e and the back side 6f of the handle, the increase in weight can be suppressed, which is preferable. Moreover, if the thicker frame portions 10 and 20 are formed only on the front side 6e or only on the back side 6f of the handle with increasing thickness, it is considered that it could be provided as a comb for right-handed or left-handed users.

[0112] Furthermore, in order to simplify the specifications, it is also possible to consider making a structure in which the concave portions 30a, 30b, 32a to 32d and the convex portions 31a, 31b, 33a to 33d formed on the surrounding contour of the handle 6 are omitted.

[0113] Furthermore, in the case where the width dimensions H2 and H2′ (length dimensions more than 1 / 3 of the width dimensions H1 and H1′) are separated by the interval between the opposing edging portions 11 and 21 (or 12 and 22) as shown in Figures 9(a) and 9(b), if it is difficult to do so because the width dimensions H1 and H1′ of the handle 6 are not large, it is also conceivable to shorten the width dimensions H2 and H2′ to less than 1 / 3 of the width dimensions H1 and H1′, and then connect the edging portions 11 and 21 (or 12 and 22) without spacing.

[0114] Furthermore, although the width dimensions H1 and H1′ of the handle 6 are not large, the edging portions 11, 12, 21, and 22 formed from the thick frame portions 10 and 20 can be omitted when it is desirable to ensure a larger area encompassing the front 6e and back 6f of the handle. With the edging portions 11, 12, 21, and 22 omitted, the thick frame portions 10 and 20 become a wall shape where the inner side of the handle is surrounded by the periphery 6c and 6d of the handle 6, maximizing the area encompassing the front 6e and back 6f of the handle.

[0115] [Example 2]

[0116] Figures 11 to 1 8 indicates the comb 50 with a handle according to the second embodiment of this utility model. The comb 50 with a handle according to the second embodiment is also a type of comb called a scraper comb, but compared with the comb 1 with a handle in the first embodiment, it is a type with an overall increased thickness. The basic structure is the same as that of the comb 1 with a handle in the first embodiment. The characteristic is that the back side rough frame portion 60 and the tooth side rough frame portion 70 formed on the peripheral contour of the handle 56 are retained in the desired range, and the back side rough frame portion 60 and the tooth side rough frame portion 70 are not formed in the vicinity of the rear end 56b of the handle.

[0117] Specifically, in the second embodiment, the comb 50 with a handle has multiple comb teeth 53 protruding in a direction orthogonal to the length direction of the comb back 52. A first comb protection portion 54 and a second comb protection portion 55 extend from the front end side 52a and the rear end side 52b of the comb back 52 in the length direction, and a handle 56 extends from the rear end side 52b of the comb back 52. The thickness T11 of the comb portion of the comb 50 (the portion composed of the comb back 52 and the multiple comb teeth 53, etc.) is (refer to...). Figure 14 , Figure 15 The thickness T1 of the comb back 2 in the first embodiment is greater than that of the first embodiment (refer to...). Figure 6 , Figure 7 The thickness T11 is set to approximately 4 mm, which is about twice the thickness T1 of the first embodiment.

[0118] Furthermore, the back of the comb 52 has multiple elliptical through holes 58 formed at equal intervals, extending from its front side 52e to its back side 52f along the Z-axis. Additionally, the handle 56, with its overall slender, plate-like shape, is as follows... Figures 11-13 As shown, the handle front end 56a, which is connected to the rear end side 52b of the comb back 52 and the second comb protection part 55, has the widest width (along the Y-axis direction) on the side connected to the comb back 52 and the second comb protection part 55. Furthermore, the handle 56 forms a total of three first handle through holes 57a to third handle through holes 57c, extending from the handle front 56e to the handle back 56f.

[0119] Furthermore, such as Figure 12 As shown, in the surrounding contour of the handle 56, a first back-side concave portion 80a, a first back-side convex portion 81a, a second back-side concave portion 80b, and a second back-side convex portion 81b are sequentially formed on the back-side periphery 56c from the front end 56a side of the handle, and 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 are sequentially formed on the tooth-side periphery 56d from the front end 56a side of the handle.

[0120] Additionally, in the surrounding contour of the shank 56, the back periphery 56c and the tooth periphery 56d, which are in a relative relationship along the Y-axis direction, respectively form a thickness dimension T12 (see reference). Figure 14 , Figure 15 The thickness of the comb back is 52 mm, dimension T11 (refer to). Figure 14 , Figure 15 Large, thick frame portions 60 and 70. However, in the second embodiment, these thick frame portions 60 and 70 are not formed to the rear end of the handle 56b.

[0121] Figure 17(a) shows that in Figure 12 The schematic cross-sectional view of the face of the shank 56 cuts through the most concave portion of the first back-side recess 80a of the back-side periphery 56c by the B1-B1 line (a line parallel to the Y-axis direction). In this figure 17(a), the back-side periphery 56c, which is the lower side, has a back-side rough frame portion 60 (first rough frame portion), and the tooth-side periphery 56d, which is the upper side, has a tooth-side rough frame portion 70 (second rough frame portion).

[0122] The back-side rough frame portion 60 has a thickness dimension T12 in the direction along the Z-axis (thickness direction), from one end 60a of the back-side frame that becomes the front side 56e of the handle to the other end 60b of the back-side frame that becomes the back side 56f of the handle. In the comb according to the second embodiment, at the portion from the cut surface in FIG17(a) ( Figure 12 The thickness of the handle 56 is also the greatest within the range from the part shown by line B1-B1 to the first back side convex part 81a.

[0123] Furthermore, as described above, the comb 50 with handle according to the second embodiment has a larger overall thickness than the comb 1 with handle according to the first embodiment. Therefore, this thickness T12 is a larger value than the thickness T2 of the back side rough frame portion 10 of the first embodiment shown in FIG. 9(a) (as an example of the actual value of the thickness T12, it is considered to be set to about 8.4 mm). It should be noted that the back side frame end 60a and the back side frame end 60b, which are the two ends in the thickness direction of the back side rough frame portion 60, are respectively chamfered and the corners are rounded, and the surface corresponding to the back side perimeter 56c near these two ends is flat.

[0124] Furthermore, the back-side rough frame portion 60 forms a back-side first edging portion 61 on the handle front 56e side of its inner circumference, and a back-side second edging portion 62 on the handle back 56f side. In detail, the back-side first edging portion 61 is formed from one end 60a of the back-side frame, which is one end side in the thickness direction of the handle 56, toward the handle front 56e, which is the inner side of the handle 56, and the back-side second edging portion 62 is formed from the other end 60b of the back-side frame, which is the other end side in the thickness direction of the handle 56, toward the handle back 56f, which is the inner side of the handle 56.

[0125] The first back-side edging portion 61 on the front side 56e of the handle has a predetermined width (meaning the width dimension along the Y-axis) of the curved shape of the concave portions 80a, 80b and convex portions 81a, 81b along the back-side periphery 56c of the handle 56. Furthermore, the first back-side edging portion 61 is formed to include a slope (a slightly convex, bulging curved surface) that tapers in thickness (dimension along the Z-axis) from one end 60a of the back-side frame on the periphery 56c of the handle 56 towards the front side 56e of the handle 56 on the inner side. It should be noted that the portion shown in Figure 17(a)... Figure 12 The predetermined width (width along the Y-axis) of the first edging portion 61 on the back side of the part shown by line B1-B1 in the figure can be set to about 7.5 mm as an example.

[0126] Furthermore, in FIG17(a), the second back edge portion 62 is symmetrical (reversed left and right) to the first back edge portion 61, and is shaped to include a slope (a slightly curved and convex curved surface) that is inclined in such a way that the thickness dimension (the dimension along the Z-axis direction) of the back frame 60b, which is the back edge 56c, which is the peripheral side of the handle 56, becomes thinner towards the handle back surface 56f, which is the inner side of the handle 56.

[0127] On the other hand, the toothed rough frame portion 70, which is the upper side in Figure 17(a), is symmetrical (reversed) to the back rough frame portion 60. The length from one end 70a of the toothed frame that is the front side 56e of the handle to the other end 70b of the toothed frame that is the back side 56f of the handle is set as the thickness dimension T12. The corners of the toothed frame that are the two ends in the thickness direction, one end 70a and the other end 70b, are chamfered and rounded. The surface corresponding to the toothed periphery 56d near the two ends is flat.

[0128] Furthermore, the toothed frame portion 70 also forms a first toothed edging portion 71 on the inner circumference of the handle front face 56e side and a second toothed edging portion 72 on the handle back face 56f side. Specifically, a first toothed edging portion 71 of predetermined width (width along the Y-axis) is formed from one end 70a of the toothed frame, which is one end in the thickness direction of the handle 56, toward the handle front face 56e, which is the inner side of the handle 56; and a second toothed edging portion 72 of predetermined width is formed from the other end 70b of the toothed frame, which is the other end in the thickness direction of the handle 56, toward the handle back face 56f, which is the inner side of the handle 56. It should be noted that the portion shown in FIG17(a) ( Figure 12 The dimensions of the predetermined width (width along the Y-axis) of the toothed first edging portion 71 and the second edging portion 72 (the portion shown by line B1-B1 in the diagram) are also, as an example, set to about 7.5 mm, similar to the back first edging portion 61 described above.

[0129] The first edging portion 71 of the tooth side is formed in a shape that includes a slope (a slope that is slightly curved into a convex shape and bulges out) that is inclined in such a way that the thickness (the dimension along the Z-axis) of the tooth side frame 50a, which is the peripheral side of the tooth side 56d, towards the handle front 56e, which is inside the handle 56, decreases. In addition, the second edging portion 72 of the tooth side, in FIG17(a), is formed in a shape that makes the first edging portion 71 of the tooth side symmetrical (reversed left and right), and is formed in a shape that includes a slope (a slope that is slightly curved into a convex shape and bulges out) that is inclined in such a way that the thickness (the dimension along the Z-axis) of the tooth side frame 50b, which is the peripheral side of the tooth side 56d, towards the handle back 56f, which is inside the handle 56, decreases.

[0130] Furthermore, as described above, the back-side rough frame portion 60 and the tooth-side rough frame portion 70 shown in FIG17(a) are formed in Figure 12The opposite back periphery 56c and the opposite tooth periphery 56d of the most concave part of the first back side concave part 80a (the part shown by line B1-B1) are separated by a width dimension H12 (equivalent to the dimension from the back side first edge end 61a to the tooth side first edge end 71a in FIG. 17(a)).

[0131] The handle front 56e, corresponding to the width dimension H12, is flat, making it easy to press the handle when the fingers are placed on it. Furthermore, to ensure sufficient area for the fingers to rest on the handle front 56e, the width dimension H12 is at least one-third the length of the width dimension H11 of the handle 56 in the portion shown in FIG. 17(a). Specifically, it is conceivable that the width dimension H11 is set to approximately 26 mm and the width dimension H12 to approximately 11.5 mm, but these values ​​are not strictly limited.

[0132] The structure involving the width dimension H12 is also the same in the structure involving the spacing between the back side second edging portion 62 and the tooth side second edging portion 72 on the back side of the handle back 56f. That is, the back side second edging portion 62 of the back side rough frame portion 60 and the tooth side second edging portion 72 of the tooth side rough frame portion 70 are separated by the length of the width dimension H12, and the handle back 56f corresponding to the width dimension H12 is also flat.

[0133] On the other hand, Figure 17(b) shows the application in Figure 12 A schematic cross-sectional view showing the surface of the handle 56 cut off by the B2-B2 line (a line parallel to the Y-axis) at the portion between the first handle through hole 57a and the second handle through hole 57b. In the handle comb 50 according to the second embodiment, since the aforementioned back side rough frame portion 60 and tooth side rough frame portion 70 are not formed near the rear end 56b of the handle, the back side rough frame portion 60 and tooth side rough frame portion 70 are not present at the portion involved in the B2-B2 line.

[0134] Therefore, at the location along line B2-B2 shown in Figure 17(b), the handle 56 has a rectangular cross-section with a constant thickness T14 from the lower back periphery 56c to the upper tooth periphery 56d, forming the front and back sides of the handle 56e and the handle 56f respectively. However, the handle 56 of the comb 50 as a whole is as... Figure 14 , Figure 15As shown, its thickness decreases towards the rear end 56b of the handle. Therefore, the thickness T14 of the part shown in Figure 17(b) (the part along line B2-B2) is slightly larger than the thickness T13 at the rear end 56b of the handle (T14 > T13. As an example, T14 can be set to about 4.5 mm and T13 can be set to about 3.8 mm).

[0135] like Figure 14 , Figure 15 As shown, in the comb 50 with handle according to the second embodiment, the range in which the back-side rough frame portion 60 and the tooth-side rough frame portion 70 are formed is defined as the range shown by the length dimension L12, which is half (1 / 2) of the total length dimension L11 of the handle 56 (the dimension along the X-axis), starting from the front end 56a of the handle (corresponding to the range near the back of the comb), extending beyond dimension L13 towards the rear end 56b of the handle. The rough frame portion end 56g that becomes the end of this dimension L13 coincides with the end on the rear end 56b side of the handle 56 where the second through hole 57b is formed in the handle 56.

[0136] Therefore, in the second embodiment, the thickness of the back-side rough frame portion 60 and the tooth-side rough frame portion 70 of the comb 50 with handle decreases toward the front end 56a of the handle (see reference). Figure 14 , Figure 15 (Figure 18) The thickness dimension is the largest within the range including the part shown in Figure 17(a) above (the part shown by line B1-B1), and the thickness dimension gradually decreases from this range toward the end of the thick frame 56g.

[0137] Thus, the overall thickness of the comb 50 with handle in the second embodiment is larger than that of the comb 1 with handle in the first embodiment. Therefore, the range of the back side rough frame portion 60 and the tooth side rough frame portion 70 formed on the periphery of the handle 56 is also within the required range (the range of size L12 + size L13) mentioned above. This minimizes the increase in weight of the handle 56 caused by the rough frame portions 60 and 70. Furthermore, when the handle 56 is held by the fingers, the area with a larger thickness formed by the rough frame portions 60 and 70 is ensured in the area where the fingers are in close contact (the area near the back of the comb), thus ensuring good grip.

[0138] Furthermore, various modifications of the comb 50 with a handle according to the first embodiment can also be applied to the comb 1 with a handle according to the second embodiment. Additionally, in cases where a further reduction in the weight of the comb 50 with a handle is desired, the forming range of the thicker frame portions 60 and 70 can be limited to, for example, the aforementioned dimension L12 (see reference). Figure 14 , Figure 15 The area shown is the area near the back of the comb.

[0139] [Example 3]

[0140] Figures 19 to 2 6 indicates the comb 100 with a handle according to the third embodiment of this utility model. The comb 100 with a handle according to this third embodiment is also a type of comb called a scraper comb, similar to the first and second embodiments, but it is a type with a smaller overall size compared to the combs 1 and 50 with handles in the first and second embodiments, although its basic structure is the same as the comb 1 with handles in the first embodiment. The comb 100 with a handle according to the third embodiment is characterized in that the predetermined width (referring to the width dimension along the Y-axis direction) of each of the edging portions 111, 112, 121, and 122 formed on the back side of the peripheral contour of the handle 106 and on the inner periphery of the tooth side of the edging portion 120 is smaller than that of the combs 1 and 50 with handles in the first and second embodiments, and the angle of the bevel of each of the edging portions 111, 112, 121, and 122 is larger.

[0141] Specifically, in the third embodiment, the comb 100 with a handle has multiple comb teeth 103 protruding in a direction orthogonal to the length direction of the comb back 102. A first comb protection portion 104 and a second comb protection portion 105 extend from the front end side 102a and the rear end side 102b of the comb back 102 in the length direction, and a handle 106 extends from the rear end side 102b of the comb back 102. The thickness T21 of the comb portion (the portion composed of the comb back 102 and the multiple comb teeth 103, etc.) of the comb 100 (refer to...) Figure 22 , Figure 23 The thickness T1 of the back 2 of the comb in the first embodiment (refer to) Figure 6 , Figure 7 The same (for example, the thickness T21 is set to about 2mm).

[0142] Furthermore, the back of the comb 102 has multiple elliptical through holes 108 formed at equal intervals, extending from its front side 102e to its back side 102f along the Z-axis. Additionally, the handle 106, with its overall slender, plate-like shape, is as follows... Figures 19-21 As shown, the handle front end 106a, which is connected to the rear end side 102b of the comb back 102 and the second comb protection part 105, has the widest width (along the Y-axis direction) on the side connected to the comb back 102 and the second comb protection part 105. Furthermore, the handle 106 forms a total of three first handle through holes 107a to third handle through holes 107c, extending from the handle front 106e to the handle back 106f.

[0143] And, as Figure 20As shown, in the surrounding contour of the handle 106, a first back-side concave portion 130a, a first back-side convex portion 131a, a second back-side concave portion 130b, and a second back-side convex portion 131b are sequentially formed on the back-side periphery 106c from the front end 106a side of the handle. 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 are sequentially formed on the tooth-side periphery 106c from the front end 106a side of the handle.

[0144] Additionally, in the surrounding contour of the handle 106, the back periphery 106c and the tooth periphery 106d, which are relatively related along the Y-axis direction, respectively form a thickness dimension T21 that is greater than that of the comb back 102 (see reference). Figure 22 , Figure 23 Large thickness dimension T22 (refer to) Figure 22 , Figure 23 The coarse frame portions 110 and 120 of the comb with handle according to the third embodiment are not formed to the rear end 106b of the handle, but compared with the comb with handle according to the second embodiment, the coarse frame portions 110 and 120 are formed to the vicinity of the rear end 106b of the handle.

[0145] Figure 25(a) shows that in Figure 20 The schematic cross-sectional view of the face of the handle 106 cuts through the C1-C1 line (a line parallel to the Y-axis) of the most concave portion 130a of the first back-side recess 106c. In Figure 25(a), a back-side rough frame portion 110 (first rough frame portion) is formed on the lower back-side periphery 106c, and a tooth-side rough frame portion 120 (second rough frame portion) is formed on the upper tooth-side periphery 106d.

[0146] The length of the back side rough frame portion 110 from one end 110a, which becomes the front side 106e of the handle, to the other end 110b, which becomes the back side 106f of the handle, along the Z-axis direction (thickness direction), is a thickness dimension T22 (as an example of the actual value of the thickness dimension T22, it is considered to be set to about 4.7 mm). In addition, the back side frame ends 110a and 110b, which become the two ends in the thickness direction of the back side rough frame portion 110, are chamfered and the corners are rounded, and the surfaces corresponding to the back side perimeter 106c near these two ends are flat.

[0147] Furthermore, in the comb with a handle according to the third embodiment, in Figure 20In the middle, the most protruding part of the first back side convex part 131a of the back side periphery 106c has the largest thickness in the area in front and behind it in the X-axis direction (as an example of the thickness of the most protruding part of the first back side convex part 131a, it is considered to be about 5 mm larger than the aforementioned thickness T22 example of about 4.7 mm).

[0148] Furthermore, the back side rough frame portion 110 forms a back side first edging portion 111 from one end 110a of the back side frame that is one end side in the thickness direction toward the front side 106e of the handle that is the inside of the handle 106, and forms a back side second edging portion 112 from the other end 110b of the back side frame that is the other end side in the thickness direction toward the back side 106f of the handle that is the inside of the handle 106.

[0149] The first edging portion 111 on the back side of the handle front 106e side is an edge shape with a predetermined width (referring to the width dimension along the Y-axis direction) of the curved shape of the concave portions 130a, 130b and convex portions 131a, 131b along the back periphery 106c of the handle 106, but the proportion of this width dimension along the Y-axis direction in the width dimension of the handle 106 is smaller than that of the combs 1, 50 with handles involved in the first and second embodiments. Specifically, the portion shown in FIG25(a) ( Figure 20 The predetermined width (width along the Y-axis) of the first edging portion 111 on the back side of the part shown by line C1-C1 in the figure is set to about 3.6 mm as an example.

[0150] It should be noted that the first back edge portion 111 has a shape that includes a beveled surface that is thinner in thickness (dimension along the Z-axis) from one end 110a of the back frame that becomes the peripheral edge 106c of the handle 106 towards the handle front 106e that becomes the inner side of the handle 106. This is the same as the combs 1 and 50 with handles involved in the first and second embodiments. However, as mentioned above, since the width dimension along the Y-axis is small, the angle of the beveled surface relative to the handle front 106e is larger than that in the first and second embodiments.

[0151] Furthermore, in FIG. 25(a), the second back-side edging portion 112 is symmetrical (reversed left and right) to the aforementioned first back-side edging portion 111, and has a shape that includes a beveled surface that is thinner in thickness (dimension along the Z-axis direction) from the other end 110b of the back-side frame that forms the peripheral edge 106c of the handle 106 towards the handle back face 106f that forms the inner side of the handle 106. As described above, the required width (width dimension along the Y-axis direction) of these first back-side edging portions 111 and second back-side edging portions 112 is smaller than that of the edging portions 11, 12, 61, 62 of the combs 1, 50 with handles according to the first and second embodiments, so the angle of the beveled surface relative to the handle front face 106e is larger than the angle of the beveled surfaces of these edging portions 11, 12, 61, 62.

[0152] On the other hand, the toothed rough frame portion 120, which is the upper side in Figure 25(a), is a structure that is symmetrical (reversed) to the back rough frame portion 110, but the angle of the slope of the shape itself is slightly different. The toothed rough frame portion 120 has a thickness dimension T22, which is the same as that of the back rough frame portion 110, from one end 120a of the toothed frame that is the front side 106e of the handle to the other end 120b of the toothed frame that is the back side 106f of the handle. The corners of the toothed frame that are the two ends in the thickness direction, one end 120a and the other end 120b, are chamfered to make the corners rounded, and the surface corresponding to the toothed periphery 106d near the two ends is flat.

[0153] Furthermore, the toothed frame portion 120 also forms a first toothed edging portion 121 of a predetermined width (width along the Y-axis) from one end 120a of the toothed frame toward the front side 106e of the handle 106, which is the inner side of the handle 106, and a second toothed edging portion 122 of a predetermined width (width along the Y-axis) from the other end 120b of the toothed frame toward the back side 106f, which is the inner side of the handle 106. The edging portions (first toothed edging portion 121 and second toothed edging portion 122) of the toothed frame portion 120 are slightly smaller in predetermined width (width along the Y-axis) than the edging portions (first back edging portion 111 and second back edging portion 112) of the back frame portion 110. As a specific example, it can be considered to be about 3.2 mm.

[0154] The first edging portion 121 of the tooth side has a shape that includes a bevel (a slightly curved, convex surface) that slopes in a manner that thins from one end 120a of the tooth side frame toward the inner side of the handle 106e (handle surface) of the handle 106 in the Z-axis direction. The second edging portion 122 of the tooth side, as shown in FIG25(a), has a shape that makes the first edging portion 111 of the tooth side symmetrical (reversed left and right), and has a shape that includes a bevel (a slightly curved, convex surface) that slopes in a manner that thins from the other end 120b of the handle tooth side frame toward the inner side of the handle 106f of the handle 106 in the Z-axis direction.

[0155] The required width (width dimension along the Y-axis) of these tooth-side first edging portions 121 and back-side second edging portions 122 is also smaller than that of the edging portions 21, 22, 71, 72 of the combs 1, 50 with handles involved in the first and second embodiments. Therefore, the angle of the bevel relative to the back of the handle 106f is larger than the angle of the bevel of these edging portions 21, 22, 71, 72.

[0156] Furthermore, as described above, the back-side rough frame portion 110 and the tooth-side rough frame portion 120 shown in FIG25(a) are formed in Figure 20 The most concave part of the first back side recessed part 130a (the part shown by line C1-C1) is opposite to the back side perimeter 106c and the tooth side perimeter 106d, but the back side first edging part 111 of the back side rough frame part 110 and the tooth side first edging part 121 of the tooth side rough frame part 120 are separated by a width dimension H22 (equivalent to the dimension from the back side first edge end 111a to the tooth side first edge end 121a in FIG. 25(a).

[0157] The handle front 106e, corresponding to the width dimension H22, is flat, thus making it easy to press the handle front 106e with fingers when gripping it. Furthermore, to ensure sufficient area for fingers to rest on the handle front 106e, the width dimension H22 has a length that is at least one-third the width dimension H21 of the handle 106 shown in FIG. 25(a).

[0158] As a specific example, consider setting the width dimension H21 to approximately 23.5 mm and the width dimension H22 to approximately 17.2 mm. With such numerical settings, the proportion of width dimension H22 within the width dimension H21 of the handle 106 is the largest in the third embodiment (from the first to the third embodiments). This is because combs with reduced overall size are generally difficult to hold stably. Therefore, even in the smaller handle comb 100 of the third embodiment, the proportion of width dimension H22 is increased to ensure stable grip, thus widening the flat handle front 106e. Furthermore, the aforementioned values ​​for width dimensions H21 and H22 are merely examples and are not limited to these values.

[0159] The structure involving the width dimension H22 is also the same in the structure of the spacing between the back side second edging portion 112 and the tooth side second edging portion 122 on the back side of the handle back 106f. That is, the back side second edging portion 112 of the back side rough frame portion 110 and the tooth side second edging portion 122 of the tooth side rough frame portion 120 are separated by the length of the width dimension H22, and the area of ​​the handle back 56f corresponding to the width dimension H22 is also flat.

[0160] On the other hand, Figure 25(b) shows the application in Figure 20 A schematic cross-sectional view of the surface of the shank 106 cut off by the C2-C2 line (a line parallel to the Y-axis direction) at the portion between the first shank through hole 107a and the second shank through hole 107b. Figure 25(b) also shows the back-side rough frame portion 110 formed on the back-side periphery 106c and the tooth-side rough frame portion 120 formed on the tooth-side periphery 106d, but the shank 106 as a whole... Figure 22 , Figure 23 As shown in Figure 26, its thickness becomes thinner towards the rear end 106b of the handle. Therefore, the thickness T24 of the handle 106 shown in Figure 25(b) is smaller than the thickness T22 shown in Figure 25(a).

[0161] However, in the part shown in Figure 25(b) Figure 20 The area shown by line C2-C2 has a back-side rough frame portion 110 and a tooth-side rough frame portion 120. Therefore, the thickness dimension T24 is greater than the thickness dimension T23 of the shank 106 at the rear end 106b of the shank (refer to...). Figure 22 , Figure 23 (Figure 26) Larger (T22 > T24 > T23).

[0162] Furthermore, since the aforementioned recessed portions 130a, 130b, 132a-132d and convex portions 131a, 131b, 133a-133d are formed on the periphery 106c and 106d of the handle 106, the width dimension of the handle 106 and the spacing between the edging portions are sometimes slightly different values ​​in each location. Therefore, in FIG. 25(a), the width dimension of the handle 106 is represented by H21, and in FIG. 25(b), the width dimension of the handle 106 is represented by H21′. Similarly, in FIG. 25(a), the width dimension of the area encompassing the front 106e and back 106f of the handle is represented by H22, and in FIG. 25(b), the width dimension of the area encompassing the front 106e and back 106f of the handle is represented by H22′.

[0163] In addition, such as Figures 20-23 As shown in Figure 26, the comb 100 with a handle according to the third embodiment does not form a thick frame portion 110, 120 near the rear end 106b of the handle; it is formed only by the thickness of the handle 106 itself. The formation of the thick frame portion 110, 120 is limited to a portion that is half the size of the first handle through hole 107a in the X-axis direction, and the thick frame portion 110, 120 is not formed in the range from this portion to the rear end 106b of the handle.

[0164] Thus, the comb 100 with handle according to the third embodiment is characterized in that, since the overall size is smaller than that of the combs 1 and 50 with handle according to the first and second embodiments, the inclination of the bevel 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 of each edging portion relative to each other (for example, the width dimension H22 shown in FIG. 25(a)) is increased, ensuring a wider range of flat handle surface, and even with a smaller size, it is easy to place fingers on the handle surface.

[0165] Furthermore, in the comb 100 with handle according to the third embodiment, various modifications of the combs 1 and 50 with handle according to the first and second embodiments can also be applied, and the structure of the combs 1 and 50 with handle according to the first and second embodiments can also be applied to the comb 100 with handle according to the third embodiment.

[0166] Industrial application potential
