BACKGROUND ARTJapanese patent application publication No. 2006-524521A (United States patent application publication No. US2006/0271071, and PCT application publication No. WO2004/095973) discloses a conventional plucking cylinder of a depilatory device. The conventional depilatory device comprises a housing, the plucking cylinder, a pinching mechanism, and a plucking mechanism. The housing is formed at its one end with a head. The plucking cylinder is supported to the head. The plucking cylinder carries a plurality of pinching units. Each of the pinching units has a stationary blade and a movable blade. Each of the stationary blade and the movable blade has an inside surface. The movable blade is disposed to have its inside surface in an opposed relation to the inside surface of the stationary blade. The movable blade is configured to be movable toward and away from the stationary blade. Therefore, the movable blade is configured to be movable between a pinch position and an opened position. The movable blade in the opened position is spaced from the stationary blade to have a gap between the movable blade and the stationary blade. Therefore, the movable blade in the opened position is spaced from the stationary blade by a gap width W defined by the gap. The movable blade in the pinch position closes the gap. The pinching mechanism is configured to the move the movable blade between the opened position and the pinch position. Consequently, the inside surface of the movable blade in the pinch position is cooperative with the inside surface of the stationary blade to pinch the hair in the gap. The plucking mechanism is configured to rotate the plucking cylinder in order to rotate the stationary blade and the movable blade in the pinch potion. Consequently, the plucking cylinder plucks the hair between the stationary blade and the movable blade in the pinch position. In this manner, the depilatory device removes the user's hair from the user's skin.
Each of the pinching unit has a hair introducing direction. The hair introducing direction is perpendicular to the gap width and is perpendicular to a radial direction of the plucking cylinder. That is, the pinching unit is arranged to have the stationary blade and the movable blade with their lengths along the circumferential direction. Therefore, the pinching unit has a depilatory area having a width parallel to the axis of the plucking cylinder and a length parallel to the circumferential direction of the plucking cylinder. The gap between the stationary blade and the movable blade is narrow. Consequently, the conventional depilatory device is configured to pluck the user's hair in a narrow depilatory area defined by the gap along the circumferential direction of the plucking cylinder and the length of the first blade and the second blade. Therefore, there is a necessity to use the depilatory device many times in order to depilate the user's hair
DISCLOSURE OF THE INVENTIONThis invention is achieved to solve the above problem. An object in this invention is to provide a depilatory device which is configured to pluck the user's hair in a large depilatory area at one time.
In order to solve the above problem, the depilatory device for removal of human hairs in this invention comprises a housing, a plucking means, a pinching mechanism, and a plucking mechanism. The housing is formed at its upper end with a head. The plucking means includes a plucking cylinder which is supported to the head. The plucking cylinder is driven to rotate about a longitudinal axis of the plucking cylinder. The plucking cylinder carries a plurality of pinching units at a circumference surface of the plucking cylinder. Each pinching unit is composed of a first blade and a second blade which are arranged in an opposed relation with each other. At least one of the first blade and the second blade is movable toward and away from the other of the first blade and the second blade to move between an opened position and a pinch position. The first blade and the second blade in the opened position are configured to form a gap between the first blade and the second blade. The first blade and the second blade in the pinch position is configured to close the gap for pinching the hair in the gap between the first blade and the second blade. Each pinching unit has a hair introducing direction which is perpendicular to a gap width of the gap for introducing the hair between the first blade and the second blade. Each pinching unit has the hair introducing direction which is perpendicular to a radial direction of the plucking cylinder. A pinching mechanism is configured to move the at least one of the first blade and the second blade between the opened position and the pinch position. The plucking mechanism is configured to rotate the plucking cylinder for plucking the hair pinched to the first blade and the second blade. The pinching units are arranged to have their introducing directions. The hair introducing directions are inclined with respect to the longitudinal axis as well as a circumferential direction of the plucking cylinder.
With this configuration, each of the pinching units has a depilatory area along the circumferential surface of the plucking cylinder. The depilatory area is defined between the first blade and the second blade. The depilatory area has a pinching width along the longitudinal axis of the plucking cylinder, and has a pinching length along the circumferential direction of the plucking cylinder. The hair introducing direction is inclined with respect to the circumferential direction of the plucking cylinder as well as the longitudinal axis of the plucking cylinder. Therefore, the pinching width of the pinching unit in this invention is larger than the pinching width of the pinching unit which has pinching length parallel to the circumferential direction of the plucking cylinder. Therefore, with this configuration, the pinching unit is configured to pinch the hairs in the large width. Consequently, this configuration makes it possible for the depilatory device to pluck the hairs from a large width along the plucking cylinder.
It is preferred that the pinching units are arranged along a direction parallel to a longitudinal direction and spaced from each other in said longitudinal axis.
In this case, the pinching units are configured to receive the hairs from a broad length along the longitudinal axis of the plucking cylinder. Therefore, the depilatory device is configured to pluck a large amount of the hairs per one rotation of the plucking cylinder. Therefore, this configuration makes it possible to enhance an efficiency of plucking the hair from the skin in one rotation of the plucking cylinder.
It is preferred that each of the pinching units has a depilatory area which is defined between the first blade and the second blade and which extends along the circumferential surface so as to have a pinching width along the longitudinal axis within depilatory area. The plucking cylinder has a depilatory length along the longitudinal axis in the circumferential surface. The pinching units are arranged within the depilatory length. A sum of the pinching widths is equal to or larger than the depilatory length.
In this case, the pinching units are configured to receive the hair from a full depilation length along the longitudinal axis of the plucking cylinder. Therefore, the depilatory device is configured to pluck a large amount of the hair per one rotation of the plucking cylinder.
It is preferred that the pinching units are arranged in a plurality of rows spaced circumferentially of the plucking cylinder. Each row includes a plurality of the pinching units which are spaced from each other along the longitudinal axis.
It is also preferred that the pinching units in the row are staggered from the other pinching units in the other adjacent rows.
In this case, the depilatory device is configured to pluck a large amount of the hair per one rotation of the plucking cylinder.
It is preferred that at least one of said pinching units is disposed to have its hair introducing direction which is differently inclined with respect to that of the other pinching units in same row.
In this case, the pinching units are configured to pinch the hairs which are grown toward a various direction.
It is also preferred that at least one of the pinching unit is disposed to have its introducing direction which is oppositely inclined with respect to that of the other pinching unit in same row.
It is more preferred that the pinching units on opposite length ends in same row has their hair introducing directions which are oppositely oriented with respect to each other.
In this case, the pinching units stretch the user's skin according to the rotation of the plucking cylinder on the skin. Consequently, the hairs are erected according to the plucking cylinder which runs on the skin. As a result, the pinching units pinch the hairs easily. Therefore, this configuration makes it possible for the plucking cylinder to enhance efficiency of plucking the hairs.
It is preferred that the pinching units are composed of a set of first pinching units and a set of second pinching units. A set of the first pinching units is arranged in series with a set of the second pinching units. The first pinching units are arranged to have said hair introducing direction which is oppositely oriented with respect to said hair introducing direction of said second pinching units. The number of said first pinching units is equal to the number of said second pinching units.
It is more preferred that each said pinching units has a leading end with respect to a rotation direction of the plucking cylinder. The pinching units are disposed within each half length of the plucking cylinder to have the leading ends directed axially outwardly from the lengthwise center of the plucking cylinder.
In this case, the plucking cylinder stretches the skin axially outwardly of plucking cylinder. Therefore, the plucking cylinder is configured to stretch the skin uniformly such that the pinching units erect the hair of the skin. That is, this configuration also makes it possible for the plucking cylinder to enhance efficiency of plucking the hairs.
It is preferred that the plucking cylinder further carries a plurality of projections at the circumferential surface. The projections are arranged between the pinching units such that the pinching units and projections are arranged in the row. The projection has a projection length. The projection length extends along the circumferential surface, and is inclined with respect to the introducing direction of the adjacent pinching units in the same row.
The plucking cylinder with this configuration is urged to the skin through the pinching units and the projections. That is, the plucking cylinder applies the uniform pressure to an entire axial length of the plucking cylinder.
It is preferred that the plucking means includes a plurality of said plucking cylinders. The rotation mechanism is configured to rotate all cylinders in a same rotation direction.
It is preferred that the head includes a guard covering said plucking cylinder. The guard having an opening through which said cylinder is exposed.
It is more preferred that the opening is divided by a plurality of cross bars each of which extends in an inclined manner with respect to the longitudinal axis of the plucking cylinder as well as the circumferential direction of the plucking cylinder.
It is most preferred that the cross bars extends in parallel with the introducing direction of adjacent one of said pinching units.
In this case, the hairs which are inserted through the opening is directed by the cross bars along a direction which is parallel to the hair introducing direction of the pinching units. The hairs directed parallel to the hair introducing direction is easily pinched by the pinching units. Therefore, this configuration makes it possible for the depilatory device to enhance the efficiency of plucking the hairs.
It is more preferred that the pinching units in the row is composed of a set of first pinching units and a set of second pinching units. Each pinching unit has a leading end with respect to a rotation direction of the plucking cylinder. Each projection has a leading end with respect to the rotation direction of the plucking cylinder. Each of the first pinching units and the second pinching units are disposed to have their leading ends directed axially outwardly from a lengthwise center of the plucking cylinder. The projection between the first pinching units is directed axially inwardly from the lengthwise end of the plucking cylinder. The projection between the second pinching units is directed axially inwardly from the lengthwise end of the plucking cylinder.
In this case, the first pinching unit is cooperative with the projection between the first pinching units to stretch the skin. Similarly, the second pinching unit is cooperative with the projection between the second pinching units to stretch the skin. That is, the pinching units are cooperative with the projections to stretch the skin. Therefore, the hairs of the skin are erected according to the stretch of the skin. The erected hairs are easily pinched by the pinching units. In this manner, this configuration makes it possible for the plucking cylinder to enhance the efficiency of pinching the hairs.
The depilatory device in this invention is explained with attached drawings.
As shown in
The pinching units 300L are disposed at a left half of the plucking cylinder in
The stationary plate 210L includes a pair of stationary blades 23L, a coupling plate 22L, and guide plates 24L. The coupling plate 22L is formed into flat, is formed to have a parallelogram, and is formed with a hole 25. The coupling plate 22L has one side coupled to a bottom end of the stationary blade 23L, and has the other side opposite from the one side coupled to a bottom end of the stationary blade 23L. The stationary blade 23L is defined as a second blade. The stationary blade 23L has a length along the one side of the coupling plate, a thickness, and a height along a direction perpendicular to the coupling plate. The stationary blades 23L are formed into flat. Therefore, the stationary blade 23L has an inside face and an outside face which is in an opposite relation to the inside face. The stationary blade has one height end with an edge which is outwardly curved. The stationary blade 23L has one length end with a leading end 233L and the other length end with the trailing end 234L with respect to the rotation direction T of the plucking cylinder 16. The leading end 233L is coupled to the guide plate 24L which extends toward a direction inclined with respect to the length of the stationary blade 23L.
The movable plate 220L has a movable blade 31L, a fulcrum plate 33L, and a guide plate 32L. The movable blade 31L is defined as a first blade. The movable blade 31L has a length, a thickness, and a height. The movable blade 31L is formed into flat. The movable blade 31L has an inside face and an outside face which is opposite to the inside face. The inside face of the movable blade 31L is formed with a groove which extends along a length of the movable blade. It is noted that the groove of the inside face of the movable blade 31L is not shown in the illustrations. However in
The holder 250L is disposed at the left half of the plucking cylinder shown in
The support plates 40 are formed into rectangular shape to have a length along the longitudinal axis of the plucking cylinder 16. The support plates 40 are disposed on the circumferential surface of the plucking cylinder 16 such that each of the support plate 40 covers the recess 46. Therefore, the support plate 40 is arranged along the circumferential surface of the plucking cylinder 16. The support plate 40 is provided for mounting the stationary plate 210L, 210R, the movable plate 220L, 220R and the holders 250L, 250C, 250R. The stationary blade 23L mounted on the support plate 40 is located in an opposed relation to the movable blade 31L. In addition, the pinching units are mounted on the support plate 40 and are arranged along the length of the support plate 40. Consequently, as shown in
The actuation bars 36a to 36f in
The actuation bars 36a to 36f are configured to receive pressure from rollers 9 which are disposed at a tip of the head 7. When the actuation bar 36a to 36f receives the pressure along the longitudinal axis, the actuation bar 36 is moved into the insertion hole 19. The actuation bars 36a to 36f are cooperative with the roller 9 to define a pinching mechanism.
Because the coupling plate 22L is formed to have the parallelogram, the stationary blades 23L have the pinching length along the circumferential surface of the plucking cylinder 16. In addition, because the coupling plate 22L is formed to have the parallelogram, the pinching length of the pinching unit 300L is inclined with respect to the circumferential direction of the plucking cylinder 16 as well as the longitudinal axis of the plucking cylinder 16. Meanwhile, it is preferred that the pinching unit is disposed to have the pinching length inclined at 12 degrees to 13 degrees with respect to the circumferential direction of the plucking cylinder 16. The gap between the movable blade 31L and the stationary blade 23L receives the hairs along the pinching length. Therefore, the length direction of the pinching length is defined as a hair introducing direction HD for introducing the hairs into the gap between the inside faces of the stationary blade 23L and the movable blade 31L. This hair introducing direction is perpendicular to the gap width of the gap between the stationary blade 23L and the movable blade 31L. The hair introducing direction which is parallel to the pinching length is inclined with respect to the circumferential direction of the plucking cylinder 16 as well as the longitudinal axis of the plucking cylinder 16. Therefore, the hair introducing direction is inclined at 12 degrees to 13 degrees with respect to the circumferential direction of the plucking cylinder 16. However, the inclination angle of the hair introducing direction with respect to the circumferential direction is not limited to 12 degrees to 13 degrees. It is preferred that the hair introducing direction is inclined at 30 degrees with respect to the circumferential direction of the plucking cylinder 16.
In addition, as shown in
Furthermore, the stationary blade 23L is cooperative with the movable blade 31L to define a depilatory area D therebetween in
The holder 250L is mounted on the support plate 40 such that the holder 250L is located between the stationary blades 23L. Consequently, the projection 28L, 28R and 28C are carried by the plucking cylinder 16 to be located on the circumferential surface of the plucking cylinder 16. In addition, the coupling plate 22L is interposed between the holder 250L and the support plate 40. The projection 28L is arranged between the pinching units 300L. Consequently, the projection 28L, 28C, 28R and pinching units 300L, 300R are arranged in the row. The projection 28L has the projection length which is inclined with respect to the hair introducing direction of the adjacent pinching units 300L. Therefore, the projection 28L is arranged to have a leading end 288L with respect to the rotation direction of the plucking cylinder 16. The projection 28L is arranged to have the leading end 288L which is directed axially inwardly from the lengthwise end of the plucking cylinder 16.
The holder 250C is mounted on the support plate 40. Consequently, the projection 28L is arranged between the pinching unit 300L and the pinching unit 300R. Therefore, the projection 28C has the projection length which is inclined with respect to the hair introducing direction of the adjacent pinching unit 300L and the adjacent pinching unit 300R. Subsequently, the fixing pin 44 is inserted through the plucking cylinder 16 such that the fixing pin 44 passes through the holes 34 and the holes of the leg 29L, 29C, 29R. Consequently, the movable blade 31L swings about a tip of the fulcrum plate 33L according to the movement of the actuation bar 36a. Consequently, the movable blade 31L swings about a tip of the fulcrum plate 33L according to the movement of the actuation bar 36a.
In this manner, the pinching units 300L, 300R are disposed on the circumferential surface of the plucking cylinder 16. In particular, a set of the pinching units 300L is disposed on the left half of the circumferential surface of the plucking cylinder 16. A set of the pinching units 300R is disposed on the right half of the circumferential surface of the plucking cylinder 16. As shown in
The gears 6 are provided for rotation of the plucking cylinder 16. In particular, as shown in
The drive source 4 is provided for rotating one of the gears 17. The drive source 4 is such as a motor and a battery. The drive source 4 is started upon the switch 3 being pressed.
The depilatory device 1 is operated as follows. To begin with, the plucking cylinders 16 are urged against the user's skin through the opening of the guard 10 of the head 7. Consequently, the hairs are inserted into the head 7 through the opening with the cross bars. Subsequently, the switch 3 is pressed. Upon the switch 3 is pressed, the battery starts supplying electrical power to the motor 4. When the motor 4 is energized by the battery, the motor 4 rotates one of the gears 6 through a connecting shaft 400. Therefore, rotation movement of the gears 6 is transmitted to the plucking cylinders 16 through the gears 6. Accordingly, the plucking cylinders 16 are rotated in the rotation direction T shown in
At this moment, the rollers 9 continuously apply the pressure along the longitudinal axis to one of the pads 39 of the actuation bars 36a to 36f which is located at the tip of the head 7. According to the pressure from the rollers 9, the actuation bar 36a is moved toward the inside of the plucking cylinder 16 along the insertion hole 19. Upon the actuation bar 36a moving toward the inside of the plucking cylinder 16, the movable blade 31L is swung about the lower end of the fulcrum plate 33L. Therefore, according to the movement of the actuation bar 36 toward the inside of the plucking cylinder 16, the movable blade 31L is moved toward the stationary blade 23L such that the gap between the movable blade 31L and the stationary blade 23L is closed. That is, the movable blade 31L is moved into the pinch position. Therefore, the hairs in the gap are pinched by the stationary blade 23L and the movable blade 31L.
The motor 4 continuously rotates the plucking cylinder 16 along the rotation direction T. Therefore, the pinching units 300L carried by the plucking cylinder 16 are rotated about the shaft 47 while pinching the user's hairs within the depilatory area. Consequently, the plucking cylinder 16 plucks the user's hairs. When the plucking cylinder 16 is rotated along the rotation direction while the pinching unit 300L pinching the user's hairs, the actuation bar 36a is moved from a tip of the head to the lower end of the head 7. Therefore, according to the rotation of the plucking cylinder 16, the pressure applied to the actuation bar 35a from the rollers 9 is removed. Therefore, the spring 45 applies the spring biases to the actuation bar 36a so that the actuation bars 36a is moved toward an outside of the plucking cylinder along the longitudinal axis. Upon the actuation bars 36a to 36f are moved toward the outside of the plucking cylinder 16 along the longitudinal axis, the movable blade 31L is moved away from the stationary blade 23L. That is, the movable blade 31L is moved into the opened position. Consequently, the pinching units 23L release the user's hair. In this manner, the rollers 9 apply the pressure to the actuation bars 36a to 36f in order, and the plucking cylinder continuously plucks the user's hairs. In addition, this plucking cylinder 16 has the pinching units. The pinching units 300L, 300R are arranged in rows 20 which are arranged along the circumferential direction. Therefore, the depilatory device 1 is configured to pluck the hairs many times per one rotation. Consequently, the depilatory device 1 is configured to pluck a large amount of the hairs per one rotation of the plucking cylinder 16.
The depilatory device 1 in this invention has the pinching units 300L which has a large pinching width.
As above mentioned, plucking cylinder 16 has the pinching units which includes the stationary blade 23L, and the movable blade 31L. Each of the stationary blade 23L and the movable blade 31L are arranged in an opposed relation to each other such that the stationary blade 23L has the inside face which is faced with the inside face of the movable blade 31L. Therefore, the stationary blade 23L is cooperative with the movable blade 31L to define the depilatory area. The depilatory area has the pinching length and the pinching width. The pinching length is defined as the hair introducing direction for introducing the hair into the gap between the stationary blade 23L and the movable blade 31L. The pinching width is defined by a distance between the leading end 233L of the stationary blade 23L and the trailing end 244L of the movable blade 31L. The hair introducing direction is inclined with respect to the circumferential direction of the plucking cylinder 16 and the longitudinal axis of the plucking cylinder 16. Therefore, the pinching width with this configuration is larger than the pinching width of the pinching unit which has a stationary blade and a movable blade which are parallel to the circumferential direction of the plucking cylinder 16. Therefore, the depilatory device 1 in this invention is configured to pluck the hairs from a large width along the plucking cylinder 16.
Furthermore, each of the pinching units of the depilatory device 1 in the present invention has the depilatory area along the circumferential surface so as to have a pinching width along the longitudinal axis within the depilatory area. The plucking cylinder 16 has the depilatory length along the longitudinal axis. The pinching units are disposed within the depilatory length. A sum of the pinching widths of all the pinching units 300L, 300R is equal to or larger than said depilatory length. Consequently, the depilatory device 1 in the present invention is configured to pluck the hair over an entire length of the depilation length. Therefore, there is no possibility for the depilatory device 1 in this invention to leave the hairs of the skin where the plucking cylinder rolls.
In addition, the pinching units 300L, 300R in the row are staggered from the other pinching units 300L, 300R in adjacent rows. Therefore, the depilatory device 1 in the present invention is configured to pluck the hair over an entire length of the depilation length.
Further, the pinching units 300L have the leading end with respect to a rotation direction T. The pinching units 300L is disposed within the left half length of the plucking cylinder 16 to have the leading end directed axially outwardly from the lengthwise center of the plucking cylinder. The pinching units 300R are disposed within the right half length of the plucking cylinder 16 to have the leading end directed axially outwardly from the lengthwise center of the plucking cylinder 16. Therefore, according to the rotation of the plucking cylinder 16, the user's skin is stretched by the pinching units 300L and the pinching units 300R. When the skin is stretched by the pinching units 300L and 300R, the hairs are erected. The erected hair is easily inserted into the gap of the pinching units 300L, 300R. Therefore, the plucking cylinder 16 is configured to pluck the erected hairs easily.
Furthermore, the plucking cylinder 16a is supported to the head with a predetermined mounting angle which is angularly displaced from a mounting angle of plucking cylinder 16b. In particular, the plucking cylinder 16a is supported to the head with a mounting angle which is angularly displaced at 30 degrees from the mounting angle of the plucking cylinder 16b. Consequently, this configuration makes it possible for the depilatory device 1 to pluck the hair many times.
In addition, the head includes a guard which covers the plucking cylinder. The guard has an opening through which the cylinder is exposed. The opening is divided by a plurality of cross bars. Each of the cross bars is inclined with respect to the longitudinal axis of the plucking cylinder, and also is inclined with respect to the circumferential direction of the plucking cylinder 16. That is, the cross bars is not parallel to the circumferential direction of the plucking cylinder 16. Therefore, the cross bars never cover the same portion of the skin continuously according to the movement of the depilatory device 1. Furthermore, it is preferred that the cross bars extends in parallel with the hair introducing direction of adjacent one of the pinching units. Consequently, the pinching units 300L, 300R easily pinch the hairs which are directed by the cross bars 12 of the guard 10.
In addition, the pinching units 300L has the leading end 243L which is directed axially outwardly from the lengthwise center of the plucking cylinder 16. On the other hand, the projection 28L is disposed between the pinching units 300L and has the leading end 288L which is directed axially inwardly from the lengthwise end of the plucking cylinder 16. Therefore, the projection 28L is cooperative with the pinching units 300L to stretch the skin. Consequently, the projection 28L is cooperative with the pinching units 300L to erect the hair of the skin, thereby the pinching units easily pinching the erected hair.
