DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(MODE OF TRIMMER BLADE AND TRIMMER PROVIDED WITH THE SAME)

A trimmer blade according to an aspect of the present disclosure includes a movable plate and a fixed plate. The movable plate has a plurality of movable blades including a first movable blade, and a second movable blade adjacent to the first movable blade. The fixed plate has a plurality of fixed blades including a first fixed blade, and a second fixed blade adjacent to the first fixed blade with a fixed blade groove interposed between the second fixed blade and the first fixed blade.
When at least one part of the first movable blade is located on the fixed blade groove, the second movable blade comes into contact with the first fixed blade.
According to this aspect, entering of one of the movable blades into the fixed blade groove is suppressed, and a blade edge of the entered movable blade and a blade edge of each of the fixed blades are unlikely to interfere with each other.
In the trimmer blade according to the aspect of the present disclosure, when a blade edge of the first movable blade is located on the fixed blade groove, the second movable blade comes into contact with the first fixed blade.
According to this aspect, in a case where at least one of the blade edges of the first movable blade is located on the fixed blade groove, force applied to the first movable blade is received by the second movable blade and the first fixed blade that come into contact with each other. As a result, entering of the first movable blade into the fixed blade groove is suppressed.
In the trimmer blade according to the aspect of the present disclosure, a whole of the second movable blade comes into contact with the first fixed blade.
According to this aspect, in a case where the first movable blade is located on the fixed blade groove, an area where a load to the second movable blade is received is wider compared to a case where only one part of the second movable blade comes into contact with the first fixed blade. As a result, the movable blades or the fixed blades are unlikely to warp.
In the trimmer blade according to the aspect of the present disclosure, the movable plate further includes a third movable blade adjacent to the first movable blade, and the second movable blade comes into contact with the first fixed blade, and the third movable blade comes into contact with the second fixed blade.
According to this aspect, the second and third movable blades are unlikely to warp, and entering of the first movable blade into the fixed blade groove is suppressed.
In the trimmer blade according to the aspect of the present disclosure, a maximum blade width of each movable blade is narrower than a width of the fixed blade groove.
According to this aspect, it is possible to increase a number of the movable blades included in the movable plate, compared to a case where the maximum blade width of each movable blade is wider than the width of the fixed blade groove. Therefore, an amount of hairs that can be cut per single reciprocating motion of the movable plate is increased.
In the trimmer blade according to the aspect of the present disclosure, a blade width of each fixed blade is longer than a length obtained by adding an interval between two adjacent movable blades to a blade width of each movable blade.
According to this aspect, a number of the movable blades that can come into contact with the single fixed blade is increased compared to a case where the blade width of the fixed blades is smaller than the length obtained by adding the interval between the two adjacent movable blades to the blade width of each movable blade. Therefore, the movable blades or the fixed blades are further unlikely to warp.
A trimmer according to an aspect of the present disclosure includes the trimmer blade described in any of the above [1] to [6].
According to this aspect, the blade edge of each movable blade and the blade edge of each fixed blade in the trimmer blade are unlikely to interfere with each other, and therefore even when the trimmer is used for a long period, a cutting quality is unlikely to be lowered.

(EXEMPLARY EMBODIMENT)

A configuration of trimmer 1 is described with reference to FIG. 1 to FIG. 4.
As illustrated in FIG. 1, trimmer 1 includes body 10 housing a plurality of machine elements therein, and head unit 20 mounted on body 10.
Body 10 includes grip 11, power switch 12 that turns on or off power supply of trimmer 1, and battery case 13 housing a primary battery or a secondary battery therein. Head unit 20 includes trimming blade 30 that is to be abutted on a target region, and is detachably mounted on a front end part of body 10.
As illustrated in FIG. 2, body 10 includes, inside thereof, electric motor 14 electrically connected to the battery housed in battery case 13, and motion conversion mechanism 15 coupled to an output shaft of electric motor 14. Electric motor 14 is operated when power switch 12 is turned on, and electric motor 14 stops when power switch 12 is turned off. Motion conversion mechanism 15 converts rotary motion of the output shaft of electric motor 14 into translational motion.
As illustrated in FIG. 3, trimming blade 30 includes fixed plate 31 including a plurality of fixed blades 40 (refer to FIG. 4), and movable plate 33 including a plurality of movable blades 50 (refer to FIG. 4). Fixed plate 31 and movable plate 33 face each other.
Head unit 20 further includes frame 21 that fixes fixed plate 31, guide plate 22 that guides reciprocating motion of movable plate 33, and spring 24 for pressing movable plate 33 against fixed plate 31.
Frame 21 supports fixed plate 31 from a side opposite to a side where movable plate 33 is disposed, with respect to fixed plate 31, and holds fixed plate 31 such that fixed plate 31 is not displaced. Gide plate 22 supports movable plate 33 from a side opposite to a side where fixed plate 31 is disposed, with respect to movable plate 33, and holds movable plate 33 such that movable plate 33 is not displaced.
As illustrated in FIG. 4, guide plate 22 includes mounting part 23 for mounting head unit 20 on body 10 (refer to FIG. 1). Mounting part 23 is connected to motion conversion mechanism 15 (refer to FIG. 2), when head unit 20 is mounted on body 10.
Power by electric motor 14 (refer to FIG. 2) is converted into force in a width direction of head unit 20 by motion conversion mechanism 15. Therefore, movable plate 33 reciprocates in the width direction of head unit 20 through mounting part 23 and guide plate 22. The plurality of movable blades 50 reciprocate with respect to the plurality of fixed blades 40 along with movable plate 33, and hairs sandwiched between movable blades 50 and fixed blades 40 are cut.
Spring 24 is mounted on frame 21, and presses movable plate 33 against fixed plate 31 through guide plate 22, thereby bringing fixed blades 40 and movable blades 50 into contact with each other. Spring 24 is configured by, for example, a double torsion spring.
With reference to FIG. 5 to FIG. 8, a configuration of trimming blade 30 is described.
As illustrated in FIG. 5, fixed plate 31 includes base 32 configuring a body of fixed plate 31, the plurality of fixed blades 40 that protrude from base 32, and a plurality of fixed blade grooves 41 formed between adjacent fixed blades 40.
The plurality of fixed blades 40 are arranged at equal intervals in the width direction of head unit 20 (refer to FIG. 4). The plurality of fixed blades 40 include first fixed blade 40a, and second fixed blade 40b adjacent to first fixed blade 40a with one of fixed blade grooves 41 interposed between second fixed blade 40b and first fixed blade 40a.
Each fixed blade 40 includes contact part 42 that comes into contact with each movable blade 50, and blade edges 43 formed on a side facing movable blades 50 of contact part 42. Blade edges 43 are formed on both sides of each protruding fixed blade 40, and support hairs that enter fixed blade grooves 41.
Each fixed blade 40 further includes front end part 44 located on a side closer to a front end than contact part 42, and thick part 45 that is formed in front end part 44, and swells on a side opposite to movable blade 50.
Movable plate 33 includes base 34 configuring a body of movable plate 33, the plurality of movable blades 50 that protrude from base 34, and the plurality of movable blade grooves 51 formed between adjacent movable blades 50.
The plurality of movable blades 50 are arranged at equal intervals in the width direction of head unit 20. The plurality of movable blades 50 include first movable blade 50a, and second movable blade 50b adjacent to first movable blade 50a with one of movable blade grooves 51 interposed between second movable blade 50b and first movable blade 50a, and third movable blade 50c adjacent to first movable blade 50a with one of movable blade grooves 51 between third movable blade 50c and first movable blades 50a on a side opposite to second movable blade 50b.
Each movable blade 50 includes contact part 52 that comes into contact with fixed blades 40, and blade edges 53 formed on a side facing fixed blades 40 of contact part 52. Blade edges 53 are formed on both sides of each protruding movable blade 50, and cut hairs flowing in movable blade grooves 51 by the reciprocating motion of movable blades 50.
In trimming blade 30, blade width WA (refer to FIG. 8) of contact part 42 of each fixed blade 40, a width of each fixed blade groove 41, blade width WB (refer to FIG. 8) of contact part 52 of each movable blade 50, and a width of each movable blade groove 51 are set as shown in the following.
In a case where at least one of blade edges 53 of each first movable blade 50a is located on one of fixed blade grooves 41, second movable blade 50b adjacent to first movable blade 50a comes into contact with first fixed blade 40a.
For example, when movable blades 50 move in a direction from second fixed blade 40b to first fixed blade 40a, a whole of one of blade edges 53 located on a side in advancing direction of first movable blade 50a moves onto one of fixed blade grooves 41 from second fixed blade 40b, and then second movable blade 50b comes into contact with first fixed blade 40a.
Until one part of one of blade edges 53, on a side opposite to the advancing direction, of first movable blade 50a moves onto first fixed blade 40a, second movable blade 50b continues to be in contact with first fixed blade 40a.
Second movable blade 50b comes into contact with first fixed blade 40a. Third movable blade 50c comes into contact with second fixed blade 40b. Second movable blade 50b wholly comes into contact with first fixed blade 40a.
As illustrated in FIG. 6, length LA of thick part 45 in a longitudinal direction of each fixed blade 40 is shorter than length LB of front end part 44. Thickness TA of contact part 42 of each fixed blades 40 is substantially the same as thickness TB of contact part 52 of each movable blade 50, and is thin.
In a case where thickness TA of contact part 42 is thinner, when cutting is performed while a side of fixed blades 40 is abutted on a target region, hairs can be cut short. In a case where thickness TB of contact part 52 is thinner, when cutting is performed while a side of movable blades 50 is abutted on the target region, hairs can be cut short.
As illustrated in FIG. 7, each movable blade 50 is tapered, and a maximum blade width of each movable blade 50 is narrower than a width of each fixed blade groove 41. A width of thick part 45, which is a blade width of front end part 44 of each fixed blade 40, is wider than a blade width on a side of front end part 44 of contact part 42.
As illustrated in FIG. 8, blade width WA of contact part 42 of each fixed blade 40 is longer than a length obtained by adding interval P between two adjacent movable blades 50, which are movable blades 50a and 50b, to blade width WB of each movable blade 50.
With reference to FIG. 8 to FIG. 10, action of trimming blade 30 is described.
Trimmer 1 (refer to FIG. 1) is used without mounting of an attachment (not illustrated) on body 10 (refer to FIG. 1).
FIG. 9 is a sectional view illustrating a case where a user cuts hairs while making the side of fixed blades 40 of trimming blade 30 abut on skin 100. As illustrated in FIG. 9, when trimmer 1 (refer to FIG. 1) is operated while thick part 45 of each fixed blade 40 is abutted on skin 100, in a case where first movable blade 50a is located on one of fixed blade grooves 41 (refer to FIG. 8), force for warping fixed blades 40 is applied to fixed blades 40.
At this time, second movable blade 50b comes into contact with first fixed blade 40a. The force for warping fixed blades 40 is received by second movable blades 50b and first fixed blade 40a that come into contact with each other. Therefore, even when the above force is applied, fixed blades 40 are unlikely to warp.
As a result, entering of first movable blade 50a into one of fixed blade grooves 41, namely, a state illustrated by a two-dot chain line in FIG. 8 is suppressed, and blade edges 53 of movable blades 50 and blade edges 43 of fixed blades 40 are unlikely to interfere with each other.
FIG. 10 is a sectional view illustrating a case where the user cuts hairs while making the side of movable blades 50 of trimming blade 30 abut on skin 100. As illustrated in FIG. 10, when trimmer 1 (refer to FIG. 1) is operated while the side of movable blades 50 is abutted on skin 100, in a case where first movable blade 50a is located on one of fixed blade grooves 41 (refer to FIG. 8), force for warping movable blades 50 is applied to movable blades 50.
At this time, second movable blade 50b comes into contact with first fixed blade 40a. The force for warping movable blades 50 is received by second movable blade 50b and first fixed blade 40a that come into contact with each other. Therefore, even when the above force is applied, first movable blade 50a is unlikely to warp.
As a result, entering of first movable blade 50a into one of fixed blade grooves 41, namely, the state illustrated by the two-dot chain line in FIG. 8 is suppressed, and blade edges 53 of movable blades 50 and blade edges 43 of fixed blades 40 are unlikely to interfere with each other.
According to trimming blade 30, the following effects are further obtained.

(1) In a case where one part of first movable blade 50a is located on one of fixed blade grooves 41, and the other part of first movable blade 50a is located on second fixed blade 40b, even when the one part of first movable blade 50a is supported by second fixed blade 40b, there is a fear that the other part of first movable blade 50a enters one of fixed blade grooves 41 depending on magnitude of load applied to first movable blade 50a.
According to trimming blade 30, in a case where at least one of blade edges 53 of first movable blade 50a is located on one of fixed blade grooves 41, force applied to first movable blade 50a is received by second movable blade 50b and first fixed blade 40a that come into contact with each other, and therefore a fear that first movable blade 50a enters one of fixed blade grooves 41 is further reduced.
(2) According to trimming blade 30, a whole of second movable blade 50b comes into contact with first fixed blade 40a. Therefore, in a case where first movable blade 50a is located on one of fixed blade grooves 41, an area where load to second movable blade 50b is received is wide compared to a case where only one part of second movable blade 50b comes into contact with first fixed blade 40a. Therefore, movable blades 50 or fixed blades 40 are further unlikely to warp.
(3) In a case where first fixed blade 40a and second fixed blade 40b are different in surface roughness, in a case that second movable blade 50b and third movable blade 50c which are in a state where one of or both of second movable blade 50b and third movable blade 50c are warped come into contact with fixed blades 40, there is a fear that first movable blade 50a then enters one of fixed blade grooves 41.
On the other hand, there is a case where each surface roughness, of fixed blades 40, on contact surfaces with movable blades 50 is different from one another. Herein, when an arbitrary one of fixed blades 40 is assumed as a reference fixed blade, fixed blades 40 which are positionally closer to this reference fixed blade are likely to have surface roughness similar to the same of the reference fixed blade.
According to trimming blade 30, second movable blade 50b comes into contact with first fixed blade 40a, and third movable blade 50c comes into contact with second fixed blade 40b, and therefore those movable blades 50 are unlikely to warp. Therefore, the fear that first movable blade 50a enters one of fixed blade grooves 41 is further reduced.
(4) According to trimming blade 30, the maximum blade width of each movable blade 50 is narrower than the width of each fixed blade groove 41. Therefore, it is possible to increase a number of movable blades 50 included in movable plate 33, compared to a case where the maximum blade width of each movable blade 50 is wider than the width of each fixed blade groove 41. Therefore, an amount of hairs that can be cut per single reciprocating motion of movable plate 33 is increased.
(5) According to trimming blade 30, blade width WA of contact part 42 of each fixed blade 40 is longer than the length obtained by adding interval P between two adjacent movable blades 50 to blade width WB of each movable blade 50. Therefore, a number of movable blades 50 that can come into contact with single fixed blade 40 is increased compared to a case where blade width WA of each fixed blade 40 is smaller than the length obtained by adding interval P between two adjacent movable blades 50 to blade width WB of each movable blade 50. As a result, movable blades 50 or fixed blades 40 are further unlikely to warp.
(6) According to trimming blade 30, thick part 45 is formed in front end part 44 of each fixed blade 40, and therefore blade edges 43 of each fixed blade 40 are unlikely to come into contact with skin 100 in a case where the user makes the side of fixed blades 40 abut on skin 100. Therefore, skin 100 is unlikely to be stimulated.
(7) According to trimming blade 30, thick part 45 swells on the side opposite to movable blades 50 of front end part 44. Therefore, when a surface, on the side of movable blades 50, of each fixed blade 40 is subjected to finish-machining, thick part 45 does not prevent operation of a tool that performs the finish-machining. As a result, the surface, on the side of movable blades 50, of each fixed blade 40 is easily subjected to the machining, and machining accuracy of the surface is improved, compared to a case where thick part 45 swells on the side of movable blades 50 of front end part 44.
(8) According to trimming blade 30, length LA of thick part 45 is shorter than length LB of front end part 44. Therefore, a length of each hair after cutting in a case where cutting is performed while the side of fixed blades 40 is abutted on the target region is determined by thickness TA of contact part 42. Therefore, in a case where cutting is performed while the side of fixed blades 40 is abutted on the target region, each hair can be cut short.
(9) According to trimming blade 30, the width of thick part 45, which is the blade width of front end part 44 of each fixed blade 40, is wider than the blade width, on the side of front end part 44, of contact part 42. Therefore, movement of hairs flowing in movable blade grooves 51 to outside is easily prevented by thick part 45 formed on each fixed blade 40. As a result, hairs moving to the outside are easily entered movable blade grooves 51 again, and then an amount of hairs that can be cut by movable blades 50 is increased.
(10) According to trimming blade 30, thickness TA of contact part 42 is substantially the same as thickness TB of contact part 52. Therefore, a length of each hair after cutting in a case where the cutting is performed while the side of fixed blades 40 is abutted on the target region, and a length of each hair after cutting in a case where the cutting is performed while the side of movable blades 50 is abutted on the target region are unlikely to vary.
(11) In a case where thickness TA of contact part 42 of each fixed blade 40, and thickness TB of contact part 52 of each movable blade 50 are further reduced, when a load is applied thereto, the fixed blades and the movable blades are easily warped. However, according to trimming blade 30, as described in above (1), second movable blade 50b, third movable blade 50c, first fixed blade 40a and second fixed blade 40b receive the load, and therefore even when fixed blades 40 or movable blades 50 are pressed against the target region, fixed blades 40 or movable blades 50 are unlikely to warp.
Thus, according to trimming blade 30, even when thickness TA of contact part 42 of each fixed blade 40, and thickness TB of contact part 52 of each movable blade 50 are further reduced, it is possible to reduce a fear that blade edges 53 of movable blades 50 and blade edges 43 of fixed blades 40 interfere with each other.
(12) Movable blades 50 are pressed against fixed blades 40 by spring 24. Therefore, even when a load is applied to movable blades 50 reciprocating, movable blades 50 are unlikely to be separated from fixed blades 40. Therefore, for example, even in a case where a large amount of hairs are cut, stable performance for cutting hairs is maintained. The higher a spring constant of spring 24 is, the more easily this effect is obtained.

On the other hand, there is a fear that the force applied to movable blades 50 by spring 24 warps movable blades 50. The higher the spring constant of spring 24 is, the stronger this tendency is likely to become. However, according to trimming blade 30, as described in above (1), second movable blade 50b, third movable blade 50c, first fixed blade 40a, and second fixed blade 40b receive the load, and therefore warp of movable blades 50 caused by the force of spring 24 is unlikely to be caused.
Thus, according to trimming blade 30, it is possible to reduce a fear that blade edges 53 of movable blades 50 and blade edges 43 of fixed blades 40 cause interfere with each other. As a result, the spring constant of spring 24 can be set to be high.

(MODIFICATIONS)

Specific modes which the trimmer blade according to this exemplary embodiment can take are not limited to the above exemplary embodiment. The trimmer blade according to this exemplary embodiment can take various modes different from the above exemplary embodiment. The following modification is an example of the various modes which the trimmer blade can take.

A relation between thickness TA of contact part 42 and thickness TB of contact part 52 is arbitrarily changeable. For example, thickness TA of contact part 42 is thinner than thickness TB of contact part 52.
According to fixed blades 40 of the modification, a blade width of front end part 44 is substantially the same as a blade width, on a side of front end part 44, of contact part 42. According to fixed blades 40 of another modification, a blade width of front end part 44 is narrower than a blade width, on the side of front end part 44, of contact part 42.
According to movable blades 50 of the modification, a blade width, on a side of front end, of contact part 52 is wider than a blade width on an intermediate or root side thereof. Therefore, movement of hairs flowing in movable blade grooves 51 to outside is easily prevented by the blade width, on the front end side, of contact part 52. As a result, hairs flowing in movable blade grooves 51 are easily cut by movable blades 50.
Formation of thick part 45 in front end part 44 of each fixed blade 40 is arbitrarily changeable.
A maximum number of movable blades 50 that can come into contact with single fixed blade 40 is arbitrarily changeable. For example, the maximum number of movable blades 50 that can come into contact with single fixed blade 40 is either one or at least three.
A width of each fixed blade groove 41 is arbitrarily changeable.
A width of each movable blade groove 51 is arbitrarily changeable.
A maximum blade width of each movable blade 50 of the modification is substantially the same as the width of each fixed blade groove 41. A maximum blade width of each movable blade 50 of another modification is wider than the width of each fixed blade groove 41.
In a case where first movable blade 50a is located on one of fixed blade grooves 41, an area of second movable blade 50b that comes into contact with first fixed blade 40a is arbitrarily changeable. For example, in a case where first movable blade 50a is located on one of fixed blade grooves 41, one part of second movable blade 50b comes into contact with first fixed blade 40a.
Blade width WA of contact part 42 of each fixed blade 40, the width of each fixed blade groove 41, blade width WB of contact part 52 of each movable blade 50, and the width of each movable blade groove 51 are arbitrarily changeable. According to trimming blade 30 of the modification, in a case

where movable blades 50 are operated, the above four widths are changed so as to obtain the following relation.
According to trimming blade 30 of the modification, for example, in a case where a center line in a short side direction of first movable blade 50a is located on one of fixed blade grooves 41, second movable blade 50b comes into contact with first fixed blade 40a.
According to trimming blade 30 of another modification, for example, in a case where one part of first movable blade 50a is located on one of fixed blade grooves 41, second movable blade 50b comes into contact with first fixed blade 40a.
In this case, when the one part of first movable blade 50a moves onto one of fixed blade grooves 41 from second fixed blade 40b, second movable blade 50b comes into contact with first fixed blade 40a. Until a whole of first movable blade 50a moves onto first fixed blade 40a, second movable blade 50b continues to be in contact with first fixed blade 40a.
